Men of Honour
Once upon a time, in a land far, far away--there lived men who dressed in suits of glittering steel... their purpose: to roam the lands in search of good deeds to be done in order to earn their salvation. The journey, although perilous, would be one of virtue and piety. Having to face down monstrous creatures and beastly men, they would sometimes take the help of other beasts in carrying out their conquests. (Of course, there were still others who may have been a bit misguided, but the myth endures, if not accurately portrayed.)

I Can't Do That Dave, now put your pants back on
In what may be the silliest poll ever taken, British women say Men Named Dave are Most Likely to be "Well Endowed". There's a whole "Top 10" and "Bottom 10" list of names... see how you stack up. The people who did the survey do this kind of thing for companies to get publicity. It works pretty well. [more inside]
Female educator & writer comments on male culture - describing video gaming males in their 20s as 'child-men', delaying traditional responsibility by decades compared to previous generations (NPR interview). Inevitable response by gaming community and others in their 20s. Further example on the change in societal isolation that leads to bowling alone, or a new social community structure being born?

Gee, Your Penis Smells Terrific!
Does Your Penis Smell Perfect? Have you ever asked yourself: "Why is it that no matter how much time and effort I put into washing my penis in the shower, I still get that awful whiff of a rancid smell throughout the day, or even right after a shower?" Nodoro has the solution. There are commercials (Are they real or parodies?) here. Via.
Hello Kitty is coming for your menfolk
MeFi is no stranger to Hello Kitty. Whether you are a fan or not (previously), her feline popularity, especially among young women, is undeniable. "But what about the guys?" you ask. Unless you were a Thai police officer, Puroland groom, or bought the existing merchandise, there just wasn't anything made especially for you. Sanrio heard the call, and Hello Kitty merchandise designed especially for men is coming soon.

The Barry White Effect
Language Log is a great linguistics blog I have been reading, and I thought that Metafilter might be interested in these posts about sex differences in language use. The (less-technical) articles to which the bloggers are responding are all within the responses, so I didn't link to them. The Barry White Effect (voice pitch seems to correlate with reproduction) - Gabby Guys (men talk more than women) - Young Men Talk Like Old Women (usage of certain words) - Gender and Tags ("Certainly we don't seem to find real women and men as sums of the characteristics attributed to them") Are any of these differences actually caused by the speakers sex? The really fascinating thing, to me, is how unbelievably hard it is to study such a distinction.

A Monumental Achievement
"The "Monuments Men" [wiki] were a group of ... men and women from thirteen nations who comprised the Monuments, Fine Arts, and Archives section during World War II....Together they worked to protect monuments and other cultural treasures from the destruction of World War II. ...They tracked, located, and ultimately returned more than 5 million artistic and cultural items stolen by Hitler and the Nazis. Their role in preserving cultural treasures was without precedent. "
Why do men pee standing up?
Why do men pee standing up? To summarize, the author thinks there's too much messy splatter when you stand up. He makes this point by starting with an Adam and Eve story, then clarifies that he too used to pee standing up, then discusses possible reasons, then shares a messy personal story, then writes another paragraph, then another, then another ...

The Return of Patriarchy by Phillip Longman
"With the number of human beings having increased more than six-fold in the past 200 years, the modern mind simply assumes that men and women . . . will always breed enough children to grow the population . . . Yet, for more than a generation now, well-fed, healthy, peaceful populations around the world have been producing too few children to avoid population decline. . . . Throughout the broad sweep of human history, there are many examples of people, or classes of people, who chose to avoid the costs of parenthood. Indeed, falling fertility is a recurring tendency of human civilization. Why then did humans not become extinct long ago? The short answer is patriarchy."

Redefining Manhood.
Angry men, searching men -- and what they can learn from girls and queers. Examinations of how feminist progress has left a lot of men adrift, and how the Left is falling down in offering help. "[Men have] had no reason to question whether a society that so perfectly suits them has created a definition of manhood that isn't 'real,' and so attempts to change society are inextricably linked to attempts to change men in ways they believe they cannot be changed. And that makes a lot of men angry." The original essay that inspired the discussion at There's Something About Men, a follow-up at Shakespeare's Sister in Redefining Manhood, a response at Pandagon, a Christian male feminist youth leader's take by Hugo Schwyzer, and an updated list of further commentary at Obligitory Reading of the Day - Femiphobia.
Ask A Man?
Ask A Man? "You have come to the right place for love, relationship and dating advice. Ask a man will provide you with the love, relationship and dating answers you seek. Our staff of amazing men have agreed to break the "man code" and tell you the absolute truth about what your man is really saying to you." For example: "Men want respect. In a man's world, men are nothing without respect. In a relationship, a man needs to know his woman respects him. "

sharing the stupid
Globally, there are about 105-107 boys born for every 100 girls. I was led to believe this was because men do stupid things that get themselves killed/injured. I wonder if this theory accounts for those times when men do something stupid that gets women killed/injured. (youTube link: video of a really stupid idea getting two women bruised up. If you laugh, it means you're going to hell.)

Men must seek consent
An advertising campaign in the UK warns men that they must seek a woman's consent before engaging in sex. The initiative is designed to combat the low conviction rate for rape but will it criminalise a generation of young men?
(some) books are for girls
Gender differences in literary taste - The Guardian (inter alia) has been reporting two English professors' studies of reading habits and feelings about books by gender. Others (newest to oldest): most revelatory books by reader gender (for men), (for women), author gender by reader gender. The methodology may not be unassailable but the findings are interesting and plausible. [viaduct vianochicken]

Body image and sex
Body Image Relates Differently To Sexual Risks Taken By Men And Women. Males with positive body image may seek multiple sexual partners and engage in unprotected sex. Women, on the other hand, may use the confidence that comes from a positive body image to resist multiple partners and insist that a condom be used when they do engage in sex.

How to Find a Man in Europe and Leave Him There
A mouse is no substitute
(all links safe for work) Some once hypothesized that as pornography became more accessible and more mainstream, men in turn would become uncontrollable, ravenous sexual beasts. I always thought this myself: a man will see something in porn that a real woman won't give him—Internet porn now caters in a click to every fetish you can imagine—and he will find a way to get it.
My ex-girlfriend, observant and intelligent beyond her years, always used to tell me the opposite: it wouldn't turn men into beasts, having their way with every woman they saw. No, it would turn them away from women completely, libidos and their ability to connect with real females weakened by the hardcore acts and impossible bodies that only porn stars could give them. The porn would crave some intrinsic desire, but leave both people in the couple lonelier and less fulfulled.
Now I think she was absolutely right.

Not That There's Anything Wrong With That...
Going on a "Man Date" (NYT link, reg. required). Two (presumably) heterosexual guys who knew each other from college go to the museum and dinner without partners -- and apparently this qualifies as a "man date," although (again presumably) there's no kiss at the end of the night or promises to call the next day. Maybe I'm cranky, but back in my day, we simply called this "spending time with a friend" and didn't plaster a thin veneer of gay panic/defensive het rationalization on it. Is the social behavior of straight males now so circumscribed that a guy having one-on-one time with a male friend outside a bar or sporting merits an article in the NYT?

Schoolgirls Unite!
Single-Sex Education When WNYC's Leonard Lopate Show decided to discuss (audio) the Summer's gender brouhaha, an interesting thing happened. The guest expected to support gender difference interpretations, Dr. Sax, and the guest expected to discuss structural challenges to women in the sciences, Dr. Bell, agreed on one solution: single-sex education. As the AP noted last summer, single-sex public education is up. Though some object on the basis that separate is never equal, Dr. Sax's organization claims both boys and girls see definite results. And even if you don't agree with Dr. Sax's reasoning, he says the studies are on his side. After all, girls schools have given us awesome ladies like Rosa Parks, Sally Ride, and me.
Easy ways to improve Men's Magazines.
Easy ways to improve Men's Magazines. Ever notice that the content in men's magazines such as GQ and Men's Health seems a bit vapid? Perhaps they could learn a thing or two from this list of suggested additions. More sharks, less cologne ads. Sounds better already, doesn't it? Now if only they could have Stallone personally deliver the copies to my door. Looks like he could use the work anyway.
White Matter and Gray Matter a Matter of the Sexes
She may not have the grey matter, but what's that matter anymore, anyway? A recent study shows that men have more gray matter, women have more white matter and in the end these differences seem to be no matter. Apparently men have more raw computing power, while women have a more efficient infrastructure -- resulting in similar general intelligence.

KatieColorado SpringsHairNormal HairColor Treated HairFine or Thin HairHeated Fast, Provided Some Volume, But No CurlMy hair curls easily. It is long (middle of my back) and fine. These rollers were far too large and did not deliver any curl. I ordered more of the smallest size to try to help my hair achieve some style. I like the body/volume, but it truly does not curl at all and the rollers are very easily tangled in my hair. I would not purchase and would have returned but they were a gift. I am highly disappointed.2 out of 2 shoppers thought this review was helpful.

About Anthony
My name is Anthony Glen Jones II. I am running for City Council Member of the 6th Ward of San Bernardino. I was born July 15, 1990 in San Bernardino, CA at Community Hospital. I am the middle age child of six siblings totaling three boys and three girls.
I will be running for the 6th Ward City as Council Member on November 3, 2015. I have been involved in my community for a long time. I understand the issues that are impacting us as neighbors and as individuals. Ultimately, I am concerned that we are going to be left with a choice to elect someone that wouldn't know how to advocate for us and to keep our community relevant on their agenda. After a lot of prayer, numerous discussions with my family, and in consultation with many of the local, involved residents of my ward, I decided to throw my hat in the ring – and I am prepared to win.
It's time to bring comprehensive change to our city. San Bernardino is bankrupt. Violent crime is rising. Over 30% of our residents live in poverty. I am fully committed to rebuilding San Bernardino back to the All-American City it once was.As a lifelong San Bernardino resident, I am committed to building a new future for San Bernardino that residents want and deserve.
San Bernardino was once a great city. Working together I know we can make it so again. I'd be honored to have your vote to serve you on our City Council. If you have any questions, please call me at (909) 254-5651.

Great car! Love it!

Everything about the car is perfect.
The car's small so the 160 HP is
definately enough. It accelerates fast
so you wont have any problems getting
into Highways, etc. It handles
perfectly and the small steering wheel
makes it even easier to handle. The
Red Dashboard Lights look really nice
but guess that's a matter of an
opinion. The engine has a really nice
sound (not too loud or soft). I find
the seats comfortable and I received
compliments from many people on its
looks. I definately reccomend this car.

need it but I don't use it. An

Amazing car for the price. Great handling, the best shifter, responsive
brakes, broad torque band, and tons of features included automatically. I am
having loads of fun driving it, and I am not even out of the break-in period yet!
The seats (firm) take a little getting used to. The styling is a bit bland
admittedly, but I am already getting over that. Complaints about the stereo
system are unfounded in my opinion, unless you like to really blast the
More comfortable seats. Center console would be nice.
I leased a 99 Integra w/auto and i felt
that it was sluggash at best with the

wants to go and go fast. GREAT CAR
When the dealership brought out the
Silver RSX with the 5 speed manual I
was hooked. I felt lucky since the RSX
sales are so good most dealerships
can't keep many in inventory. The
ergonomics are the best of any car I
have driven. The quality is so much
better than the Mercedes 230C. And the
Acura costs $8000 less fully equiped.
For me this is the perfect car to drive
to work and fun to drive on the
The drivers seat with lumbar support,
the automatic temperature control, and
the standard CD stereo system by Alpine.
The cruise control buttons on the
steering wheel need to be backlit for
night driving. A handle on the inside
of the hatchback door would be helpful
since it opens very high.

Discover a comet while on the Internet with SOHO
Posted: April 19, 2002
A new comet was discovered over the Internet by a Chinese amateur astronomer visiting the website for the Solar and Heliospheric Observatory (SOHO) spacecraft. The comet "C/2002 G3 (SOHO)" was first reported on Friday, April 12, by XingMing Zhou of BoLe city, in the XinJiang province of China, who discovered the comet while watching SOHO real-time images of the Sun on the Internet. The comet is a new comet, not belonging to any known group.
"From September 2000 to now I have been trying to find SOHO comets, and I've discovered 13 comets, one of which, designated '2001U9' and initially cataloged by the SOHO project as 'SOHO-367,' was the brightest one in the last two years," said Zhou, who previously spent more than 1,600 hours since his 1985 graduation scanning the heavens with his 15cm F/5.3 reflector telescope to discover a single comet.
"What's exciting about these near-sun comets is that we are exploring a population of comets that has never been seen before because they are very small and faint," said Douglas Biesecker, a solar physicist with L3 Com Analytics Corporation, Vienna, Va. "By the time their orbits take them close to the Sun so they become bright, they are lost in the Sun's glare and require a space-based coronagraph like that on SOHO to be seen." Biesecker, who is affiliated with the SOHO program at NASA's Goddard Space Flight Center in Greenbelt, Md., confirms potential comet discoveries as they are posted to the SOHO website.
C/2002 G3 (SOHO) will be visible in SOHO's Large Angle and Spectrometric Coronagraph (LASCO) C3 images until Saturday, April 20. The comet was first visible late in the day on Thursday, April 11. It entered the field of view at the bottom edge, almost directly under the Sun. It is moving upward to the left, and will eventually move back toward the right, exiting from the LASCO C3 field of view at the top edge, to the right of the Sun. First cataloged by the SOHO project as "SOHO-422," it has been officially designated C/2002 G3 (SOHO) by the International Astronomical Union.
The comet reached the point closest to the Sun in its orbit on April 17 at about 1:30 a.m. Eastern Daylight Time, at a distance of about 7.6 million miles (12.3 million kilometers). As the week goes on, the comet will move through the field of view more quickly.
In all these images, the shaded disk is a mask in the instrument that blots out direct sunlight, making faint comets and the dim outer atmosphere of the Sun, or the corona, visible. The white circle added within the disk shows the size and position of the visible Sun.
Solar radiation heats the comet, which in turn causes the outgassing of its water molecules and dust. The dust scatters sunlight at visible wavelengths, making the comet bright in LASCO images. The water molecules break down into oxygen and hydrogen atoms, and the hydrogen atoms interact with the coronal plasma (electrified gas that comprises the extended atmosphere of the Sun).
All the SOHO images are freely available on the SOHO web site: http://sohowww.nascom.nasa.gov/

Language and Communication in Autism: An Integrated View
ABSTRACT Children with autism spectrum disorders can have varying degrees of difficulty acquiring spoken and written language, but symptoms of communication impairment associated with social impairment are uniformly present, distinguishing autism spectrum disorders from other neurodevelopmental disabilities. Early diagnosis and early intervention involving parents can improve prognosis. Red flags for social communication problems can be observed early. This article summarizes findings from the National Standards Project of the National Autism Center, which identified 11 types of treatment, 8 of which address communication. Both contemporary behavioral approaches and naturalistic developmental approaches are included in this set.

Article: Does occupational therapy play a role for communication in children with autism spectrum disorders?[Show abstract] [Hide abstract]
ABSTRACT: This study investigates occupational therapy for early communication in children with autism spectrum disorders (ASD). The research explored the role of occupational therapists in supporting children with ASD to become better communicators by considering their inter-professional collaboration with speech-language pathologists. Convenience samples of 21 clinical occupational therapists and speech-language pathologists were recruited to participate in semi-structured audio-recorded focus groups, using a qualitative design. Distinct views included a child-centred focus from speech-language pathologists, whereas occupational therapists spoke of the child through societal viewpoints, which later pointed to occupational therapists' proficiency in enabling skill generalization in ASD. An equal partnership was consistently reported between these clinicians, who identified the same objectives, shared strategies, joint treatments, and ongoing collaboration as the four main facilitators to inter-professional collaboration when treating children with ASD. Three unique roles of occupational therapy comprised developing non-verbal and verbal communication pre-requisites, adapting the setting, educating-partnering-advocating for the child, and providing occupation-based intervention. These three themes meshed with the discipline-specific occupational therapy domains represented in the Person-Environment-Occupation framework. When working in inter-professional collaboration, speech-language pathologists and occupational therapists agree that occupational therapy is indispensable to early intervention in enabling communication in ASD.International Journal of Speech-Language Pathology 01/2014; 16(6).

Article: The effect of hypocalcemia in early childhood on autism-related social and communication skills in patients with 22q11 deletion syndrome[Show abstract] [Hide abstract]
ABSTRACT: 22q11 deletion syndrome (22qDS), also known as DiGeorge syndrome, is a copy number variant disorder that has a diverse clinical presentation including hypocalcaemia, learning disabilities, and psychiatric disorders. Many patients with 22q11DS present with signs that overlap with autism spectrum disorder (ASD) yet the possible physiological mechanisms that link 22q11DS with ASD are unknown. We hypothesized that early childhood hypocalcemia influences the neurobehavioral phenotype of 22q11DS. Drawing on a longitudinal cohort of 22q11DS patients, we abstracted albumin-adjusted serum calcium levels from 151 participants ranging in age from newborn to 19.5 years (mean 2.5 years). We then examined a subset of 20 infants and toddlers from this group for the association between the lowest calcium level on record and scores on the Communication and Symbolic Behavior Scales-Developmental Profile Infant-Toddler Checklist (CSBS-DP ITC). The mean (SD) age at calcium testing was 6.2 (8.5) months, whereas the mean (SD) age at the CSBS-DP ITC assessment was 14.7 (3.8) months. Lower calcium was associated with significantly greater impairment in the CSBS-DP ITC Social (p < 0.05), Speech (p < 0.01), and Symbolic domains (p < 0.05), in regression models adjusted for sex, age at blood draw, and age at the psychological assessment. Nevertheless, these findings are limited by the small sample size of children with combined data on calcium and CSBS-DP ITC, and hence will require replication in a larger cohort with longitudinal assessments. Considering the role of calcium regulation in neurodevelopment and neuroplasticity, low calcium during early brain development could be a risk factor for adverse neurobehavioral outcomes.European Archives of Psychiatry and Clinical Neuroscience 09/2014; 265(6).

Rated 5 out of 5 by Jack5959 Wow This hotel really knows how to take care of it's platinum members...wow! Great oceanfront suite, unbelievable view of Diamondhead with the coolest infinity pool ! Right in the middle of all the activity that goes with staying in Waikiki! I don't know why anyone would want to stay anywhere else! July 15, 2013
Rated 2 out of 5 by Disappointed37 Barn-like hotel that lacked atmosphere and quality This hotel lacked any atmosphere. We were staying in a small room at the end of a long corridor. The in room breakfast was small and over priced. We wanted to buy some bottled water and were required to go to three different floors before buying some (the vending machines had run out of water.) The rooms were noisy. Fortunately for our SPG recognition we were able to jump the enormous queue to check in. All in all, this hotel was extremely disappointing. July 12, 2013
Rated 5 out of 5 by myhira Hotel has great employees, features From check-in to check out, every employee we met was very friendly, upbeat, and professional. Definitely recommended. July 8, 2013
Rated 4 out of 5 by Jeff43 A good, centrally located property We found the hotel to be conveniently located to transportation, shops and restaurants. The view was terrific and we enjoyed seeing the turtles foraging for food every day. July 6, 2013
Rated 4 out of 5 by SydneyNick Pool Proper policing of the adult infinity pool is required. Non-guests need to be kept out. Signs stating the eligibility of those that can attend the adult pool should be erected to avoid embarrassment. July 6, 2013
Rated 4 out of 5 by Mattyg Ocean View Wonderful hotel at the end of Waikiki Beach. Great access to all the amenities of Waikiki as well as the ability to get away from the madness if you choose. Best pools in Waikiki and a terrific staff that was helpful all over the property. Would absolutely return. July 3, 2013
Rated 4 out of 5 by Beach4life Public areas are great The public lobbies, pools, and restauraunts are created with the consumer in mind. The only thing we would have changed is cleaner carpet in the guest room July 3, 2013
Rated 1 out of 5 by Dissapointed123 Disappointment Sound isolation of the rooms was dreadful. Footfall and conversation was easily transmitted through the walls. The club Rum Fire completely disrupted our sleep. Not a family friendly environment. People in the suite below were smoking pot on the balcony. July 2, 2013
Rated 4 out of 5 by DakotasMom Excellent. The hotel location is perfect. The infinity pool was the best ever. Of course, being in Hawaii, there is not much to complain about. However, the absolutely best feature of this hotel is its staff. The staff was always helpful, pleasant, and polite. They went out of their way to accommodate anything that I needed. The only awkward aspect of the hotel is the lack of dresser drawers. Although I understand the lack thereof makes the room appear larger, the room did have an "ottoman" that could have had drawers underneath for use. July 1, 2013
Rated 4 out of 5 by Serafina808 Enjoyed our stay Overall, we enjoyed our stay. Majority of the staff were helpful, knowledgeable and friendly with a few exceptions. My 3-year old granddaughter especially loved the pool/slides and the mermaid experience. One bad experience was at the Rumfire bar. My sister, granddaughter and I attempted to have lunch there. We walked in and although 3 staff members were within a few feet of us, no one looked up to acknowledge or greeted us. We looked around for a posted sign to see if we should seat ourselves and finding none asked one of the servers. We were told to sit 'anywhere' and went out to a table on the patio where we sat for 5-7 minutes. Again, no one approached or acknowledged us. I went to the bar to ask for a kids menu. The bartender said he didn't have any at the bar, but would send someone over. We waited... no one came. We eventually moved inside due to it being too hot outside (no umbrellas for sun at the tables). We took a seat and, again, waited. After another several minutes without assistance or acknowledgement, we left the restaurant (BTW~ we were given a big smile and warm greetings from a staff member when we left the restaurant and, no, my granddaughter was not misbehaving) and had hot dogs from the stand next to the pool. July 1, 2013
Rated 5 out of 5 by Pasion94 One of the best hotel's in waikiki Hotel room was clean and view was beautiful. Pool and restaurants in hotel was amazing. Staffs at the hotel were nice and caring. Definitely be coming back soon. July 1, 2013
Rated 5 out of 5 by Kauaialoha amazing! The Sheraton Waikiki never fails us...this hotel always exceeds our expectations. So convenient and comfortable for families to stay at. Mark at the front desk is phenomenal,very pleasant... and definitely a true example of exceptional customer service! Julie Loo and Laurie Kaeo... mahalo nui for the true definition of ALOHA!

Rated 2 out of 5 by Cootta Too expensive for what offered The hotel is tired! Too expensive for why is offered. Rooms small and service poor. Location great but wy over priced....never stay again! June 27, 2013
Rated 5 out of 5 by RafKam Great Stay We had a very good stay here overall, despite some initial aprehension. Check-in was a bit erratic as there was a line of guests waiting at 11pm but only 2 front desk agents, but that's probably my only complaint. Received a lovely upgrade to a Pualani Suite, which was massive and much appreciated. Location is probably the best in Waikiki, there's convenient parking, shopping mall and expensive stores, as well as convenient shops in the lobby area. The infinity pool is great, and you could always get a decent spot. The Club Lounge was great: without a doubt the best I've seen anywhere in the Americas, with a great breakfast spread, and great evening drinks and snacks. Dare I say, for a family it could even make sense to pay for Club Lounge access. Would stay again on a future trip to Oahu. June 25, 2013
Rated 4 out of 5 by Tmart8573 Good stay We recently stayed at the Waikiki Sheraton and had a great time. The hotel is very nice, offers great views of Waikiki beach and has great beach access. The only negative is that the Wi-Fi is VERY UNRELIABLE. It is everywhere but is constantly dropping and very often you cannot even get in. There is no LAN lines in the rooms so if you need reliability you will need to use the hotels computers. Overall a very good hotel with excellent staff. June 25, 2013
Rated 4 out of 5 by tiger65 Great hotel to spend an anniversary..! The staff was great...house cleaning great...room very clean and comfortable...Our anniversary was great..they bought us two drinks upon arrival....took a complementary photo....gave us a free catomoran ride...and helped in planning daily adventures....infinity pool was just terrific....the only drawback was the buffet breakfast...very expensive...but all in all a wonderful place to stay....!!!

The Beach Center at the Sheraton has everything you need for your day on the beach. Thank you Jeff for your hospitality and kindness. Can't wait till the next visit. June 17, 2013
Rated 1 out of 5 by scott4 Rooms were low quality While the lobby is very nice and the location is excellent, the rooms do not even look finished. There was literally no furniture in the room other than a bed, desk, and tv. No drawers, no dressers. Wires exposed, and a tiny bathroom. You expect alot more from the pictures online. I was greatly dissapointed. June 17, 2013
Rated 5 out of 5 1 hr free international call with resort fee My only issue is when I tried to make an international call. It did not go through so I tried again and was on the phone for 1:07 hours. I was expecting to be charged for that 7 minutes but was shocked to see it was $36!! I went to the front desk to ask to see the breakdown because I was afraid that I was charged for the whole hour and 7 minutes but they were not able to provide me that info so I am not even sure I was charged correctly. I feel that $36 for 7 minutes to England is way too high so I feel it was an error but since the can't show me the breakdown, I was stuck with it. June 17, 2013
Rated 5 out of 5 Great location, fine room, adorable pools It is located at the heart of waikiki shopping street. Pools were not very big but comfortable. Room were not big but clean and good. Breakfast was nice. June 17, 2013
Rated 3 out of 5 Don't do Club!!! Club lounge at this resort is a total waste of money - do no do it. Also, "free Internet" and "free water" - please! you pay a $25 a night resort fee, nothing is "free". The room size when requesting a 2 x adult and 2 x children was a joke. Paid a reasonable amount for this and was not happy. More frustrating was that we invited friends to join us - very embarrassed. I know your standard response will be....sorry! June 16, 2013
Rated 5 out of 5 by JeffTraveler Awesome time in Waikiki Our first trip to Hawaii, including our kids (9 & 13) and my in-laws. Great location, great room, great staff. Excellent recognition as SPG Gold. This will NOT be our last trip to Hawaii !!!! June 16, 2013
Rated 5 out of 5 by SwissHospitality computer glitch My only fault with this hotel is the billing. In the past 14 nights of stays varying in length, there is always a billing error. They do correct it but it is a hassle to have to review the bill wait for a correction and then receive 4 emails with only 1 of the 4 the corrected billing statement.Staff is very attentive and polite and i would highly recommend this hotel if you choose to stay in Waikiki. June 15, 2013
Rated 5 out of 5 by GS808 "Service Charge" at The Edge of Waikiki I am a kama'aina, and was more than happy to pay a mandatory 18% tip for a party of 6 at The Edge of Waikiki restaurant at the Sheraton Waikiki. I was NOT happy that they called it a "Service charge" on the bill, with another line under it labeled "Tip", implying that the service charge was not the mandatory 18% tip. It was very misleading. If we didn't ask our waitress what the "Service charge" was, we would have given her an additional 18% tip. This is not a nice way to treat the guests who may not ask what the service charge was for, or for non-English speaking guests. The food and atmosphere were great, but it would be better for the restaurant to list the "Service charge" as "Tip" on the receipt and then label the second line as "Additional tip", as do other restaurants in Waikiki. June 13, 2013
Rated 3 out of 5 by Fred Great improvements Aloha, I check in a lot here at Sherraton, the last two recents stay we're unsatisfy upon check in. We check as a Hot Rates guest and treated differently. We feel like we were not welcome as a guest upon check in and when we complain about our room I was not given a choice or options because our booking was booked hot rates. I believe that no matter what type of booking we should have been treated as a guest. Our confirmation shows that we are confirm in a city view with balcony but we didn't got balcony, we got a room on the six floor with a small window . Feel like a dungeons. MOD that night has not given me on option and that's not acceptable to me. I been in the hotel industry for 10 years and manage a hotel his response is unacceptable. So called next day talk to another MOD she was able to help me and moved me into a better room. I was happy after wards. June 12, 2013
Rated 3 out of 5 by AG72 This hotel is average and needs improvement From the time we checked in to the time we checked out, the service was slow in all areas of the hotel. At check in we were told we were put in a room with 2 double beds with a city view. Our reservation was for a king with an ocean front view. We were on our honeymoon and the desk person was able to find a room with a king. It had a bit of an ocean view, but was not ocean front. When we asked for a late check out (we're spg members) we were told we would have to move to a different room (this was on the last night of our stay). Needless to say, we declined the "offer" and were out of our room by the required time. June 11, 2013
Rated 5 out of 5 by Coop21 We Keep Coming Back Our initial greeting with the hotel preferred guest rep Ashley was not a good representation for the hotel. But after check-in everything else was perfect! We keep coming back to this hotel because of the wonderful accommodations, the hypnotic ocean and beautiful surroundings. June 11, 2013
Rated 2 out of 5 by jackie27 Ok didn't like that there was a long when I arrived - a line of 15 people with two desk attendants isn't the "welcome to sheraton waikiki" that I would have liked. Also, the room wasn't cleaned too well, two days in a row. The first day I let it slide, the second day, I called housekeeping to come and clean it up. June 9, 2013
Rated 2 out of 5 by Hiko Though the SPG APP Showed Availability I joined a tour from Japan and stayed at the Sheraton Waikiki. Although the SPG APP showed the availability of large ocean front rooms or suites and we fully recognize tour stay is not applicable for SPG Platinum benefit, the receptionist refused to upgrade with room charge difference payment. Also the building is too old so that the noise from isle or rooms next door sounds terrible. June 8, 2013

Also, in position and velocity of the particle at its enthe old Edison machine the grain is dropped trance into the operating space. This is so beso through a columnar space in which the operating cause in those separators the effective magnetic spaces are small spaces adjacent to the pole pieces force to cause separation is not the same for vaof the magnets, and the rest of the columnar rious paths through the operating space, but is space is not usefully employed for separation. different for different paths and may vary several It is obvious that since every particle must be hundred percent between different possibl p s passed through the operating space, for a given of a particle.

If a perfect separation had been made all the 45 My invention relates to separating machines A grains would go into fraction X, and all the B in which the operating space is a large volume grains into Y. Previously used separators howas compared with the localized and restricted ever will not approach a perfect separation beoperating spaces of the previously used separatween grains whose susceptibilities are so close tors, and particularly to machines in which the together, and it will be found that X is composed 50 magnetic field in the operating space is of a speof say 65% A and 35% B, and Y of 65% B and cial configuration. 35% A. The reason is that although the mean In separators embodying my invention the magnetic force for all paths is just sufficient to length of the operating space, measured parallel I remove particles of mass susceptibility greater to the flow of the grain is in general great in than l.5 10- and to reject those at lower mass susceptibility, on some paths the effective force is perhaps three times as strong, and all particles having such paths will be delivered to fraction X regardless of whether they are A or B. Similarly certain other paths followed by some of the particles are through regions in which the effective force due to the field is perhaps only half as great as the mean, and insufllcient to remove either A or B, which are both indiscriminately passed to fraction Y.
Thus it is seen that to make a good separation between two components whose mass susceptibilities are close together it is important that the effective magnetic force on a particle for different paths shall be substantially a constant. Previously used separators have not been able nor so far as I am aware tried so to control the configuration of the m netic field that its effect on a particle is independent of its initial path. This control is one of the objects of the present invention.
Other advantages will be apparent from the specification which follows.
In the drawings:
Fig. 1 is a longitudinal cross section of a separator embodying my invention, taken on the line C--C of Fig. 2.
Fig. 2 is a cross section on the line A-A o'i" Fig. 1.
Fig. 3 is a side view of the separator shown in Fig. 1 as seen from the direction of the arrow B.
Figs. 4 and 5 are schematic views showing a Figs. 9 to 12 inclusive are diagrams to illustrate the motions of particles in various kinds of magnetic fields.
Fig. 13 is a schematic representation in cross section of the magnetic circuit of a separator.
In Figs. 1 to 3 inclusive, I have indicated at 9 inclined tubes into which the mixture to be separated is introduced from the hopper III by feed pipe I l. Each tube 9 is placed between pole pieces i 2 whose surfaces adjacent the tube 8 are shaped soas to provide within the tube a magnetic field of suitable configuration which will be discussed later. The windings I 3 energized from some suitable source of electricity serve to supply magneto-motive force across the gaps between the pole pieces I 2. Near the lower termination of the pole pieces l3 there is placed within each tube a divider H which serves to keep apart the products of the separation and to allow them'to be conveyed into separate receptacles l5 and I6 through the discharge tubes l1 and I8 respectively.
The device may either be operated flooded with water as shown, or it may be operated dry; in the latter case the grain being dried sufficiently so that the particles do not adhere to one another. The operation of the device wet will now be described. The grain mixture, fed through I l' into hopper III descends through the tubes 9; Upon :a-rriving'adjacent to the upper extremity of the pole pieces the particlesfind themselves in a magnetic field which tends to urge the more magnetic constituents in the direction upwards and towards the right in Fig. 1.- The dots l9 sink downwards under the influence of gravity. The less magnetic particles 20 continue to slide down the lower or outer part of the tube 9 undisturbed bythe magnetic field. In some cases it may be desirable to promote turbulence in the water of the upper part of tube 9, in order that all the particles may be freed from each other to prevent entrainment of non-magnetic particles with the stream it or of magnetic particles with the stream 20. This turbulence may be achieved by the use of water jets, mechanical stirrers or the like. In many cases. however, such devices are wholly unnecessary.
The more magnetic particles move downward and pass above the divider it before they pass out\ of the magnetic field which terminates near the lower ends of the pole pieces I2. They are then discharged through the pipe it into a suitable receptacle IB. The less magnetic particles pass below the divider II and are discharged through thepipe "l1 into ll.
A modification of the type of separator shown in Fig. 1 is illustrated in Figs. 4 and 5. In Fig. 4 the space between the pole faces I 2 contains a horizontal trough 2|. This trough is filled with water up to the level 22. The grain is fed through a'pipe Ii andfails to the bottom of the trough." In the bottom of the trough 2 I is a screw conveyor-s23 suitably driven to propel the grain to the right in Fig. 5. *When'the grain reaches the operatingspace between the pole faces II the more magnetic constituents are'liftedby the mag-' netic force and riseto the surface of thewater;
A conveyor is provided which moves these more magnetic grains to the divider along the surface of the water. The divider l4 serves to keep the two constituents separated as they emerge from the operating space. A detail of practicalimportance in either form is the configuration of the pole faces 12 near the discharge end. Instead of being cut ofi squarely, as they may be at the feed end, they should be cut away according to a curve somewhat resembling that shown in Fig. 6 at l2. The purpose of this curvature is to prevent the clogging of the machine by "an unduly great convergence of magnetic field tending to hold magnetic particles at the ends of the pole faces nearest the discharge.
It will be understood that although the embodiments of the device shown in Figs. 1 to 6 are shown as operated wet, it is also possible to operate these devices dry. In the case of Fig. 4 the conveyors 23 and 24 may then be omitted and a closed tube substituted for the troughll, and
the motion of the particles through the device assured by a shaking motion of the tube possibly supplemented by an inclination of the device in direction'ofthe fiow of grain.
Fig. '7 shows another arrangement embodying my invention. In Fig. 7 the pole faces are designated at l2. Between these faces there are any number of operating spaces 9 which may be tubes as -irr-Figi 2. Immediately surrounding the axis, which is vertical, is the winding l3 serving to energize the device. The operating-spaces 9 as well as the pole faces I! are preferably of hellcoidal form, so that particles descending through 9 will at the same time undergo a rota motion about the axis. Splitters l4 placed in the spaces S-near the bottom of the device serve to separate the magnetic from the non-magnetic particles. The magnetic particles are drawn in by magnetic forces towards the axis; the less magnetic particles are kept toward the outside in their descent by the centrifugal force resulting from their rotary motion. Suitable means are provided for feeding each space 9 at the top near the periphery and for discharging the separation products at the bottom. The winding It may be closed externally through another similar device set beside the first one, if desired.
It is well known that the force exerted by a magnetic field on a particle magnetized by induction is proportional to the gradient of the quantity H where H is the field intensity, susceptibility being considered constant; and so far as I am aware in all previously used magnetic separators the force exerted on a particle increases rapidly as the particle travels in the field under the influence of magnetic forces. In these cases, therefore, a magnetic particle is always in unstable equilibrium under the influence of magnetic and gravitational forces as-regards all possible paths of motion. This kind of field is hereinafter referred to as a katadynamic field.
For reasons both of economy and of accuracy in separation and in particular in the type of separator represented by my invention it is much more desirable that a particle of a given kind while in the separating zone of a magnetic separator should be subjected to magnetic forces which either are substantially constant regardless of the particular position of the particle in the zone, or decrease as the particle moves under the influence of the magnetic force, so that if each particle is also acted on by some constant force such as gravity, it will be in either neiitral or stable equilibrium as regards motion along the line of the gradient of H. I shall now disclose out the separating space the magnitude of the gradient of the square of the field strength is either sumtantially a constant, or decreases as the value of H increases. are hereinafter referred to, respectively, as isodynamic and anadynamic.
By the term "operating space" is meant that space, zone or volume in a magnetic separator in which magnetic forces are applied to the particles to give physical separation on the basis of the magnetic susceptibilities of the particles. ,7
By the term cylindrical force field" is meant a magnetic field in which surfaces representing equal magnitudes of H are cylindrical surfaces (not necessarily of revolution). By the term "direction of the axis of a cylindrical force field" is meant the direction of the elements of these cylinders.
In other words, in a cylindrical force field corresponding points in different cross sections taken perpendicular to the axis have the same values of H.
By the term isodynamic magnetic field is meant a magnetic field in which the gradient of meant a magnetic field in which the gradient ofthe square of the field intensity decreases in magnitude in the direction in which the square of the magnetic field intensity increases.
By the term katadynamic magnetic field" is meant a magnetic field in which the gradient of the square of the field intensity increases in magnitude in the direction in which the square of the magnetic field intensity increases.
These kinds of field.
By the term isodynamic magnetic separator is meant a magnetic separator in which throughout a considerable part of the operating space the magnetic field is substantially isodynamic.
By the term anadynamic magnetic separator is meant a magnetic separator in which throughout a. considerable part of the operating space the magnetic field is anadynamic.
which is the gradient of H The derivative of this gradient with respect to y is ar and at any point a being a function of position.
\ For an isodynamic field, a is zero.
For an anadynamic field, a is finite and real.
For a katadynamic field, a. is imaginary.
In accordance with these definitions, it will be seen that the previously used magnetic separators, as pointed out above, are katadynamic.
I have illustrated in Figs. 9 to 12 inclusive the difference in the behavior of particles in the three kinds of fields above defined.-
Fig. 9 represents a particle in a katadynamic magnetic field such as is found in all previous magnetic separators of which I am aware. Assume a magnetic particle to be placed at c and the magneto motive force adjusted so that the magnetic force on the particle is just equal and opposite to its weight. If now the particle be moved ever so little above the point e, the magnetic force will exceed the weight of the particle and the particle will be drawn upward with ever-increasing acceleration until it strikes the upper pole piece at d. If the particle be moved downward ever so little from c, the magnetic force will become insufficient to sustain it and the particle will drop downward by gravity until it strikes the lower pole piece at 12. Hence the motion of a particle of given susceptibility upward or downward is determined by the initial position and velocity which it may happen to have in the operating space.
Fig. 10 also shows a katadynamic field arrangement with differently shaped pole pieces. The remarks above as to Fig. 9 apply equally to Fig. 10.
Fig. 11 represents a particle in an lsodynamic magnetic field. Assume a particle of a certain definite'susceptibility to be placed at point and the magneto motive force of the magnet adjusted so that the magnetic force on the par ticle is just equal and opposite to its weight.
If now the particle be moved up to point d, the magnetic force upon it will still hajust equal and opposite to its weight, and the same would be true if the particle were moved down to point I).
Fig. 12 illustrates the behavior of a magnetic particle in an anadynamic field. Assume a par ticle of a certain definite susceptibility be placed at point e" and the magnetomotive force adjusted so that the magnetic force is just equal and opposite to the gravitational force. If now the particle be displaced upward and released it will return to point above which the gravitational force exceeds the magnetic force for this particle, and below which the magnetic force upward exceeds the gravitational force. Therefore 0" is the position of equilibrium for this and similar particles on the line of symmetry.
If a particle of greater susceptibility than the first be placed at c" and released, it will move upward to some such position as d" at which it would be in stable equilibrium as regards vertical forces, and to which it would return if displaced either up or down from d". A particle of less susceptibility would likewise find a position of stable equilibrium at some such point as b". In general all particles of the same susceptibility will tend to be in equilibrium as regards vertical forces at the same height, and if a mixture of particles of different susceptibilities be introduced into the field the particles will tend to arrange themselves in horizontal layers at heights corresponding to their susceptibilities.
In Fig. 13 which is a schematic representation in cross section of the magnetic circuit of-a separator embodying my invention, I is the core about which is wrapped the winding 2 supplied with electric current from a suitable source. 3 and 3' are the pole pieces forming the termination of core I. Their opposing surfaces 4 and 4' are shaped to a special form which is discussed below. 5-5 represent the plane of symmetry of the device, 6-6' is a horizontal plane to which surfaces 4 and 4' are asymptotic as they are also to 5--5'. I--'I and 88' are planes parallel to 6 -6' which limit approximately the operating space of the device.
The mathematical expression of the shape of surfaces 4 and 4' to give between these planes 1-1 and 8-8 the best configuration of magnetic field is approximately x +t y= a constant. If a is zero, the field will be isodynamic. If a is finite and real, the field will be anadynamic. 6 is preferably small compared to unity. In other words, if the exponent of :r in the equation is equal to 2, the field is isodynamic; and if greater than 2, the field is anadynamic. If the exponent is less than 2, that is if a is imaginary the field is katadynamic. An analysis of the reasons for this is given below.
There is a certain magnetomotive force 215 available to drive the magnetic flux across the gap between 4 and 4'. In the region between I and 'I' and 8 and 8', where the surfaces 4 and 4' do not depart greatly from parallelism with 5-5, the distance travelled by the flux across the gap is substantially equal to the horizontal distance between 4 and 4; this distance will be designated by 2.1:. The distance above the plane 6-6 at which the gap is equal to 210 will be designated by 11. Then the magnetic field intensity H at any height 1 is equal to This involves the assumption, sufiiciently accurate for practical purposes, that the pole face is an equipotential surface.
Throughout this region the field gradient is substantially upward perpendicular to plane 6-6,
that is, parallel to the y axis. The field gradient therefore is equal to and the gradient of the square of the field, to which the force on a particle is proportional is dH y Since and in the isodynamic case s g =0, a constant, we may write Differentiating, we have dy c which is a constant, and therefore the force on a particle is a constant regardless of its position, within the space in which the assumptions are true.
Now if 6* is a small positive quantity it is obvious that the force will decrease as 1/ increases and the field will be anadynamic.
If 6 is negative, that is if a is imaginary the field will be katadynamic. The most useful fields are obtained when 6 is either zero or a small real quantity.
In ordinary language, it may be said that in the operating space of a katadynamic separator, a magnetic particle free to move in the direction of increasing field intensity cannot be kept in equilibrium by a constant force. On the other hand, in isodynamic and anadynamic separators, such a particle in the operating space could be maintained respectively in neutral or Stable equilibrium, as regards motion in the direction of the gradient of H, by a constant force.
Since, as is well known, the energy density of a magnetic field equals the energy gradient is a vector having the same direction as the gradient of H and a magnitude times as great. The expressions direction of energy gradient and direction of gradient of H are therefore synonymous, and correspond to the direction in which a particle of given positive susceptibility is urged by a magnetic field.
The word cylindrical is usedherein' in its broad mathematical sense of referring to surfaces generated by a straight line moving parallel to a given line and passing through a given curve. The term "cylindrical field refers to a field whose equipotentials are cylindrical surfaces. It is obvious that neither such a field nor its energy gradient can have any component in the direction of the elements of the cylindrical surfaces.
