Night club scene
Im hoping ill get some good replies to this. I own a D3000 (18-55mm) and i use a SB600 flash. I will be taking some photos at a local club on friday in chicago. I have taken photos before of open mics, but there was very very low lighting yet ive worked with them to come out pretty good if i say so myself lol. Point is, what type settings for my camera and flash would be good for a night club scene.

Hello Altamont and Welcome to Nikonians,
Presumably flash will be allowed in the club. If that's the case and the subject is relatively still, then your easiest option is to set the camera to P, the flash to TTL (not TTL-BL, which is the usual setting - press the MODE button on the flash to change) and start clicking. I would also raise the ISO a bit to 400 to give a bit of margin on the effective shutter speed. Take a few test shots to ensure it's working as expected.
You can also experiment with Slow-Synch once you're comfortable with the above situation. That will give you more creative opportunities, but it will be blurry a little (or a lot) depending on how fast your subject's motion is.

I bought both this book as well as the barons sat US history book.
This one dominates in that it makes it 10 times easier to understand. Barron's has a lot of unnecessary info but it is much more thorough in basically all the reading. BUTT it is many times more boring and often very hard to read and understand.
I read this book about 3 times (takes about like 3-4 hours, short read!!), did the tests and skimmed over the barrons and amazingly got a 760!!! it was weird cus on the practice tests in this book, i score no higher than 720. the barrons tests are RIDICULOUSly hard!!!! might be good just for info review. If your like me, where if the reading gets to complex then you tune out, get this one!!! Barrons is unnecessarily cus i did not learn anything from that to be honest..
*make sure you memorize the ammendments,acts,court cases, and important election dates......which leads to (down)
BUY the sparknotes flash cards!! They work pretty. welll i thought soo.
good luck kids!!!
I like the end-of-chapter quizzes too!
Before buying, I skimmed through Barron's and this book is much better. Barron's distracted me from the main points, going way too far into detail. I like that this had detailed, yet pertinent, information.
So buying off Amazon would have saved me about 8 bucks, but I had 2 weeks to study. Anyway...
Reading through it, I found it was simply written. However, I constantly found grammar and punctuation, as well as misspellings, throughout the whole book which irritated me and distracted from my reading. How could a book that costs around 20 have so many errors?
It made me realize that Kaplan was not as professional as I thought. Where the heck were the editors? Did they not proofread the book? I mean, COME ON. I'm sure there were more editions before this one, and did not anyone check the book to make sure it was all correct?
I'm sending it back to them.

Mat does not lie flat on floor. Edges curl up from roll.
I have had this in place in my garage for a few weeks now and am happy with it. I park a classic car on this mat. One small concern is that it does tend to curl up on the ends and I had to tape it. It does not appear that this "curling effect" is going to go away.

This application is a continuation-in-part of applications Ser. No. 27,171 filed Apr. 9, 1970 and Ser. No. 268,840, filed July 3, 1972, both now abandoned.
The present invention relates to a new composition of matter comprising quaternized cationic vinyllactam-acrylamide copolymers useful as flocculants and filler retention aids in paper-making.
It is an object of the present invention to provide a new and useful class of quaternized cationic vinyllactam-acrylamide copolymers.
Another object is to provide a process for making a filled paper composition while employing said copolymers.
A still further object is to provide a process for flocculating suspended solids from sewage and contaminated waters.
A further object is to provide a process for making a quaternized cationic vinyl lactam-acrylamide copolymer having a K-value less than 200 and the copolymeric product of the process.
Other objects and advantages will become manifest from the following description and disclosure.
We have discovered that in the attainment of the foregoing objects, it is necessary to prepare the quaternized cationic vinyllactam acrylamide copolymer by first copolymerizing in a polymerization apparatus from 30 to 95% by weight of an N-vinyllactam monomer with from 5 to 70% by weight of acrylamide or methacrylamide in aqueous solution with a free radical catalyst such as, for example, azobisisobutyronitrile, lauroyl peroxide, benzoyl peroxide, tertbutylperbenzoate, hydrogen peroxide plus ammonia, etc., at a neutral or slightly alkaline pH to minimize the hydrolysis of the comonomers at a temperature of from about 25° to 150° C. The resulting viscous, colorless solution (base copolymer) has a relative viscosity (1 gram of copolymer in 100 ml. water at 25° C.) of from about 5 up to about 50. The relative viscosity will depend on reaction temperature and monomer concentration. Cationic vinyllactams can be prepared by any of the known techniques such as for example as disclosed in U.S. Pat. No. 3,406,155; British Pat. No. 982,269 and British Pat. No. 887,900 which methods of cationization are hereby incorporated by reference.
In the past, quaternized copolymers of vinyl-lactam and acrylamides have been formed by first quaternizing the lactam and then subjecting the quaternized lactam to copolymerization. However, the product thus obtained varies markedly in structure from the product of the present process for the reason that the reactivity rate for the cationic moiety is significantly higher than the rate for homo- or copolymerization of the amide. Consequently, prior processes have resulted in large homopolymer blocks of the lactam in place of the present, more randomly distributed monomers or in substantially lactam homopolymer wherein the comonomer is present as terminal groups ending the homopolymer chain. These quaternized copolymers have conventionally high K-values, minimally from about 250 upwards, e.g. 400 and above.
In contrast, the products of the present invention are prepared by initially copolymerizing the lactam and amide monomers and then reacting the resulting copolymer with formaldehyde and a secondary amine to give a cationic vinyllactam-acrylamide copolymer which is finally quaternized by reaction with an ester of an inorganic acid such as for example, methyl chloride, ethyl chloride, methyl bromide, ethyl bromide, propylchloride, hexylchloride, alkylsulfates, such as dimethyl sulfate, benzylchloride, and alkyl esters of sulfonic acids to provide the desired quaternized cationic vinyllactam-acrylamide copolymer having more random distribution of monomers and a viscosity K-value less than 200.
The N-vinyllactams which are copolymerized with either acrylamide or methacrylamide are characterized by the following formula: ##STR3## wherein R is either hydrogen, methyl or ethyl group and n an integer of from 1 to 3.
As specific illustrations of such N-vinyllactams, the following are representative:
Prior to copolymerization, the free radical catalyst may be dissolved in the N-vinyllactam and the resulting solution added to a solution of the acrylamide or methacrylamide in water or other suitable solvent. The concentration of acrylamide or methacrylamide in the aqueous solution may range from 2% to 50% by weight. The pH of the solution may then be adjusted so as to be neutral or slightly alkaline with a buffer solution such as those containing dibasic sodium phosphate, dibasic potassium phosphate, sodium ammonium phosphate, and the like. The aqueous solution of the acrylamide or methacrylamide preferably comprises water or an aqueous alcoholic solution. The resulting solution may then be placed in any conventionally sealed polymerization apparatus, such as, for example, a Pyrex polymerization tube which has been cooled and evacuated. The sealed tube can be placed in a constant temperature bath for a period of time ranging from 1 to 10 hours and then transferred into a steam bath for 1 to 10 hours. The resulting viscous colorless solution has a relative viscosity from about 5 up to about 50. It may then be diluted, or concentrated, to a concentration suitable for further reaction and preferably from 5 to 25% weight by volume, with a suitable solvent such as for example, distilled water or aqueous alcohol solution. The solution of the copolymer is then reacted with formaldehyde and a secondary amine at an alkaline pH to form a cationic solution of the copolymer. This reaction can be effected in two steps e.g. by first reacting the copolymer solution with formaldehyde to form methylol acrylamide or methylol methacrylamide groups and then reacting the resulting solution with the dialkylamine, dialkanolamine, or morpholine to form the cationic copolymer. Alternatively, the formaldehyde and dialkylamine, or dialkanolamine or morpholine may be added, sequentially to the copolymeric solution or the formaldehyde and dialkylamine, dialkanolamine or morpholine may be premixed and then added to the copolymer solution. Other convenient techniques of contacting the reactants may also be employed.
The mole ratio of the said secondary amine or morpholine, formaldehyde/acrylamide or methacrylamide moiety can be varied over a wide range with there being either an excess of or less formaldehyde with respect to the secondary amine; although the preferred ratio of said secondary amine or morpholine to formaldehyde is such that there is a slight excess of the formaldehyde whereby the acrylamide or methacrylamide moiety in the copolymer will contain one or more of the cationic groups ##STR4## wherein R2, R3 and R4 are as previously defined. The resulting cationic vinyllactam-acrylamide copolymer is then quaternized in the presence of an organic ester of an inorganic acid at a temperature of from about 30° C. to about 120° C. for a period of 0.5 to 10 hours, or until at least almost 10% of the available nitrogen in the amine group is quaternized with the organic residue. The active product which results, having flocculent properties, is a quaternized cationic copolymeric N-vinyllactam containing the following moieties: ##STR5## wherein the symbols R, R1, R2, R3, R4, Z, X, n, a and b are as defined above. Preferably R2 and R3 are either methyl, ethyl, hydroxyethyl or together represent the residue of morpholine; R4 represents the organic residue of the quaternizing agent up to about 90% of unchanged hydrogen; in the total copolymeric product; preferably not more than about 70% of unchanged hydrogen; a represents from 30% to 80% by weight of the lactam moiety and b represents from 20% to 70% by weight of the acrylamide or methacrylamide moiety in the copolymer.
The following examples will serve to illustrate specific embodiments for the preparation of the cationic N-vinyllactam acrylamide copolymer and quaternization thereof. It is to be understood, however, that any of the foregoing lactams, or secondary amines and quaternizing agents may be substituted in the following Examples to provide the corresponding copolymeric quaternized product. For the sake of brevity it is to be understood that the term "acrylamide" includes both acrylamide, per se, and methacrylamide.
A 60 weight percent N-vinyl-2-pyrrolidone and 40 weight percent acrylamide copolymer was prepared by dissolving 0.024 gram of azobisisobutyronitrile in 7.2 grams of redistilled commercial N-vinyl-2-pyrrolidone. To the solution there was then added a solution of 4.8 grams of acrylamide in 100 ml. of distilled water. The pH of the solution was adjusted to 8 with 35 drops of 10 percent aqueous solution of dibasic sodium phosphate. The total volume was made up to 150 ml. with distilled water. The resulting solution was placed in a Pyrex polymerization tube, which was cooled to 0° C., evacuated, and the neck sealed off. The tube was placed in a 65° C. constant temperature bath for 3 hours, then in a steam bath for 2 hours. A N-vinyl-2-pyrrolidone-acrylamide copolymer was formed.
About 0.75 mole of a copolymer prepared as in Example 1 was reacted with 0.75 mole of formaldehyde, 1.0 mole dimethylamine at 60° C. and then treated with 2.0 moles of methylchloride per mole of acrylamide unit at 50° C. The resultant polymer had 41.5% of its nitrogen in the quaternized form.
Into a 3-liter, 4-neck flask fitted with a condenser, thermometer, dropping funnel, agitator and gas inlet tube for nitrogen blanketing there was charged 73.0 g. acrylamide and 1486 ml. distilled water. The mix was stirred until completely dissolved, and then the pH was adjusted to 7.8, with 10% Na2 HPO4.7H2 O solution. The flask was thoroughly flushed with nitrogen and 171.0 g. vinylpyrrolidone were introduced through the dropping funnel followed by 1.45 g. t-butyl peroxypivalate. The solution was heated to 50° C. and cooled as required to maintain a temperature of 50° C during the exothermic initial polymerization. After 1 hour at 50° C., the temperature was raised to 60° C. and held at 60° C. for 4 hours. The copolymeric solution was then cooled and discharged.
The base copolymer of Example 1 was quaternized by charging a copolymer solution containing 100 grams of solid and 500 ml. of distilled water into a 3-liter, 4-neck flask fitted with a condenser, thermometer, dropping funnel, agitator and gas inlet tube. After stirring to homogeneity, the pre-mixed solution which had been prepared at a temperature below 30° C. from 39.5 grams 37% formaldehyde and 47.8 grams 40% dimethylamine was added over a 20-minute period. The mixture was agitated for 2 hours at a temperature between 65° and 70° C. and the resulting solution was charged into a one-gallon stainless steel stirred autoclave. At 50° C. the solution was stirred under full cylinder pressure of methyl chloride (35 to 40 psig.) for 4 hours. The reactor was vented at 50° C. and purged with nitrogen and the resulting quaternized copolymeric product recovered.
Example 3 was repeated with the exception that 79 grams 37% formaldehyde and 95.6 grams 40% dimethylamine were employed. The resulting cationic product contains a plurality of units wherein the amino moiety contains two cationic quaternizable nitrogens. At lower concentrations of amine and formaldehyde, only the terminal nitrogen in the amino moiety may be cationized so that only one site therein is quaternizable.
A solution containing 952 grams of copolymer was prepared as in Example 2 and 492 ml. of distilled water were charged into a 3-liter, 4-neck flask fitted with a condenser, thermometer, dropping funnel, agitator and gas inlet tube and stirred to homogeneity. An equivalent amount of premixed solution of 37% formaldehyde and 40% dimethylamine as in Example 3 was added over a 20-minute period. After heating for 2 hours at 65°-70° C., the solution was charged into a one-gallon stainless steel stirred autoclave. The mixture was stirred at 50° C. under the full cylinder pressure of methyl chloride for a period of about 4 hours after which time the reactor was vented at 50° C. and purged with nitrogen and the resulting quaternized copolymeric product was recovered.
Example 5 was repeated with the exception that 2 equivalents of formaldehyde (37%) and dimethylamine (40%) were employed to provide a quaternized copolymeric product containing a plurality of amino units having two quaternized tert-amino sites per unit.
Into a 3-liter, 4-neck flask fitted with a condenser, thermometer, dropping funnel, agitator and gas inlet tube for nitrogen blanketing there was charged 122.0 g. acrylamide and 1486 ml. distilled water. The mix was stirred until completely dissolved, and then the pH was adjusted to 7.8, with 10% Na2 HPO4.7H2 O solution. The flask was thoroughly flushed with nitrogen and 122.0 g. vinylpyrrolidone was introduced through the dropping funnel followed by 1.45 g. t-butyl peroxypivalate. The solution was heated to 50° C. and cooled as required to maintain 50° C. during the exothermic initial polymerization. After 1 hour at 50° C., the temperature was raised to 60° C. and held at 60° C. for 4 hours. The copolymer solution was cooled and discharged.
Example 1 was repeated with the exception that 7.2 grams of N-vinyl-2-pyrrolidone were replaced by 7.2 grams of N-vinyl-2-piperidone. Additionally, the copolymer was treated with 1.0 mole formaldehyde and with 1.0 mole dimethylamine per mole of acrylamide unit followed by reaction with 1.0 mole of benzylchloride per mole dimethylamine, the resultant polymer had 50% of its available nitrogen in the quaternized form.
Examples 1 and 3 were repeated with the exception that 7.2 grams of N-vinyl-2-pyrrolidone were replaced by 7.2 grams of N-vinyl-2-caprolactam, and was reacted in an autoclave with 0.75 moles of formaldehyde, 1 mole dimethylamine and 1.6 moles of methyl chloride per mole of acrylamide unit. The resultant polymer had 41.5% of its available nitrogen in quaternized form.
Example 1 was again repeated with the exception that 7.2 grams of N-vinyl-2-pyrrolidone were replaced by 7.2 grams of N-vinyl-5-methyl-2-pyrrolidone and the 4.8 grams of acrylamide were replaced by 4.8 grams of methacrylamide. The product was quaternized as in Example 3.
An 8% solution of a 70/30 (weight percent) vinylpyrrolidone/acrylamide copolymer was treated with 2.3 moles of 37% formaldehyde and 2.0 moles of 37% dimethylamine per mole of acrylamide and heated to 65° for 2 hours. At 50° C. and under 40 psig. of pressure it took up 2.0 moles of methyl chloride in a 4-hour period. The product had 11.5% solids and 13.0% chlorine (dry basis). The theoretical chlorine content for replacement of one amide hydrogen and quaternization is 9.9%, for replacement of both hydrogens and quaternization 14.8%.
Three separate 80 weight percent N-vinyl-2-pyrrolidone and 20 weight percent acrylamide copolymers of different molecular weight were prepared in aqueous solution by the procedure described in Example 1, while employing isopropanol as a chain transfer agent.

As shown above the presence of an alcohol, preferably C1 to C4 alkanol functions to lower molecular weight of the copolymer by terminating the polymer chain. The products of this example were then quaternized as in Example 3.
The quaternized cationic copolymers, as above prepared, are ideally adapted as flocculating agents in the clarification of water for industrial use, e.g., silty river water, mine underground water, boiler water, raw water, drilling water, and in the settling of ore and coal fines. The dosage levels in such use may range from 0.5 to 100 parts per million of flocculating agent per volume of mineral solids. In brief, the process of flocculation consists of adding the quaternized cationic N-vinyllactamacrylamide copolymer to a given suspension with sufficient agitation to insure uniform distribution.
When the system is quiescent, the flocculated aggregates will settle out. In general, there is an optimum range for the flocculant/suspended fines ratio. At too high a concentration, the flocculant would act as a suspending agent.
The quaternized cationic copolymers are very effective in varied operations in the pulp and paper industry. The addition of 1 ounce to 1 pound (solid basis) per ton of paper pulp (cellulosic wood) fiber (dry basis) in the form of about 0.05% aqueous solution at the head box or fan pumps provides significant savings since less filler is lost in the "white water". This is particularly important when an expensive pigment like titanium dioxide is used. They are also effective in "white water" effluent wastes from bond mills and similar operations. Such wastes are readily clarified at loadings of 0.1 to 1.5 parts per million of the cationic copolymer.
It is known that cationic vinyllactam acrylamide copolymers and quaternary polyelectrolytes in general have been employed as flocculating agents and retention aids in paper making processes. It is noted, however, in this connection that the quaternized cationic vinyl pyrrolidone acrylamide copolymers of the instant invention produce an unexpected and substantially improved result over that which was previously obtained with the above-mentioned compounds. The following examples are cited to demonstrate this improved flocculation and retention characteristic which has been discovered and is disclosed herein.
The polymer of Example 1A was mixed with a raw city sewage (Easton, Pennsylvania) at various levels of flocculant solids on sewage volume. The resultant flocculation was compared after three minutes with that obtained in the same time with a commercial polyacrylamide (Dow Purifloc C-31).

As will readily be seen from the above table, the quaternized cationic vinylpyrrolidone-acrylamide copolymer of the instant invention resulted in substantially improved results in substantially lower amounts.

The procedure of Example 13 was repeated using the polymers prepared in Examples 3, 8 and 9. As a control, unquaternized cationic "poly-vinylpyrrolidone/acrylamide" was used for comparison. As will be seen from Table 2, the quaternized compounds of the instant invention resulted in far superior flocculation in far lower quantities then that which could previously be obtained with the cationic poly-vinylpyrrolidone acrylamide copolymers.
The polymer composition of Example 3 was mixed with raw river water at various levels of flocculant based upon the volume of water. The resultant clearing was rated as follows after three minutes in comparison to an unquaternized cationic polyvinyl pyrrolidone/acrylamide copolymer.

Standard Georgia Kaolin was added to dry bleached sulfite pulp (27° S.R.) at 3% consistency and mixed for 20 minutes. The resultant slurry was then diluted to 0.3% consistency and 0.2% of an alkyl ketene dimer sizing compound (Aquapel 360, Hercules Power Company) solids were added based upon the weight of the fiber. This slurry was stirred for 30 seconds and the polymer to be tested as a retention aid was added as a 0.0475% solution which amount corresponds to 8 ounces of a 100% polymer per ton of fiber dry basis. The slurry was once again hand stirred for 30 seconds and handsheets were formed therefrom. The handsheets were then pressed and dried in a steam-heated dryer. Filler retention was then determined by ashing the handsheets. As will be appreciated from Table 4, the compositions of the instant invention were substantially better as retention aids than either unquaternized cationic polyvinyl pyrrolidone acrylamide copolymers or commercially available quaternized polyacrylamide.

A 0.1% aqueous dispersion of a dry carbon black Paris II (Columbia Carbon) was prepared. A flocculant comprising 0.05% solids which flocculant corresponded to the polymer of Example 1A was added to 250 ml. of carbon black dispersion in 1 or more equal increments separated by 10 inversions of the 250 ml. cylinder containing said dispersion. The rate and quality of flocculant were determined at various times up to 5 minutes after the last inversion. The quality of the supernatant was also noted at the end of the test period. When a 0.5% solids solution of the polymer of Example 1A was added, there was immediate flocculation, moderately rapid settling, and good effluent clarity after 5 minutes. When a nonquaternized cationic PVP acrylamide copolymer was added at 1 part per million concentration there was slow flocculation which took approximately 1 minute, slow settling, and poor to fair effluent clarity after 5 minutes.
At 0.5% dispersion was prepared comprising a 38% carbon black formulation containing approximately 13% of a sulfonated napthalene formaldehyde condensate (Blancol-Permanent Black B paste) as dispersant. Bleached Kraft pulp was added to the dispersion to make a consistency of 0.02% fiber. The procedure of Example 17 was followed and as will readily be noted from Table 5, the quaternized polymer of the instant invention resulted in an excellent and rapid flocculation where as the unquaternized cationic polyvinyl pyrrolidone acrylamide copolymer required a much longer time period and a much higher concentration to obtain results which were not nearly as good as those obtained with the quaternized copolymer as can be seen from Table 5.

0.8% based upon the weight of the fiber of the carbon black dispersion of Example 17 was added to a 3% consistency bleached sulfite pulp as a dry powder. Flocculant was added from a 0.5% solids solution in a simulated fan pump addition in one or two equal increments separated by 30 seconds hand stirring. Sheets were formed from the resultant dispersion pressed and dried in a steam-heated paper dryer. As will be seen from Table 6 the flocculants and retention aids of the instant invention were far more effective than were the quaternized acrylamides which were the same quaternized acrylamides used in Example 16 or the cationic polyvinyl pyrrolidone acrylamide copolymer which was unquaternized.

The procedure of Example 19 was repeated except that the carbon black dispersion of Example 18 was added from an aqueous suspension rather than as a dry powder. As will readily be seen from the following Table 7, the flocculants of the instant invention are far superior to those previously known in the art.

A 60 weight percent N-vinyl-2-pyrrolidone and 40 weight acrylamide copolymer was prepared following the method of Example 1.
652 g. of the copolymer in 100 ml. of distilled water (100 g. solids) was cationized by reaction with 31.8 g. formaldehyde (37%) and 34.1 g. 40% dimethylamine. The reaction was carried out by first preparing a premix of the dimethylamine and the formaldehyde and maintaining the mixture at a temperature under 30° C. by cooling until addition thereof to the copolymer. The copolymer solution was charged to the reaction flask and the premixed solution added thereto over a 15 minute period. The mixture thusly obtained was maintained with agitation at a temperature of between 65° and 70° C. for two hours and the product then discharged into a two-quart container. The reaction flask was washed with 500 ml. distilled water and the wash solution added to the product. The resulting product was rolled on rollers for 40 minutes to insure homogeneity and subsequently quaternized with methyl chloride as described in Examples 24-26.
Example 21 was repeated with the exception that 24.6 g. of 37% formaldehyde were used in this instance.
Example 21 was again repeated with the exception that 19.7 g. of 37% formaldehyde were utilized in this case.
The products of Examples 21, 22 and 23 were then analyzed and evaluated. The results obtained have been set out in the following table:

The base cationic copolymers of Examples 21 to 23 (A, B and C respectively) were quaternized as hereinafter set out. 500 g. of each of the copolymers were reacted with 10 g. diethanolamine, 7 g. 50% acetic acid and 0.7 ml. 28% NH4 OH. The quaternization was carried out by heating the mixtures in each case to 50° C with agitation and holding at this temperature for 2 hours. Thereafter, a dry ice cooled condenser was installed in each reaction vessel and methyl chloride was introduced at a sufficient rate to maintain a slow reflux.
The reaction temperature was maintained at 50° C. under reflux for 3 hours. The mixtures were then cooled to room temperature and allowed to stand overnight. The reaction mixtures were examined and it was noted that reaction mixture A was slightly viscous and that B and C were thick but not gelled. The reaction mixtures A, B and C were heated to 50° C with agitation and under reflux. After 7 hours, the reaction mixtures were cooled. The reaction mixtures A and B were thick but pourable, but reaction mixture C appeared to have gelled. The results of the analysis carried out on the products of the three examples is set out in the following table:

500 g. of the copolymers were quaternized as set out in Examples 24 - 26. A total of 22 g. (A), 23 g. (B) and 25 g. (C) methyl chloride was added. In addition, after 11/2 hours (A), 13/4 hours (B) and about 2 hours (C) of refluxing, the reaction mixtures were diluted with 200 ml. water. The mixtures were cooled after 3 hours and 20 minutes and were quite viscous. The results of analysis of the products show the following:

As indicated above the quaternized copolymers having higher K-values are more viscous. At K-values of about 200, handling of the material becomes difficult and flocculant or retention aid solutions become limited to 1-2% concentration of the quaternized copolymer which significantly lowers efficacy and requires uneconomically large volumes of treating agent to provide the desired result.

Northern California Coast
Hundreds of miles of coastal hiking trails, giant redwood forests, and historic lighthouses are just a few of the things you will find on the Northern California Coast. Just north of San Francisco is the Point Reyes National Seashore. From the herds of elk to the endless miles of empty shoreline, this is the most peaceful and thought-provoking part of California Coast travel.
Within the park there is a Visitors Center. The Bear Valley visitor's center is where you can pick up area guides, and is a short walk from a Miwok Indian Village that has been recreated for visitors who stop here on their California Coast vacation. The Point Reyes National Seashore is not devoid of the fog that blankets San Francisco, so when you visit the scenic lighthouse at Point Reyes or explore the interesting cultural artifacts of the Indians that have lived in the area for thousands of years, you experience all these sights when they are wrapped in a mysterious white shroud that only adds to the haunting beauty of the California Coast. Nature buffs and hikers love to explore the nearly 150 miles of hiking trails, while camping in one of the four backcountry camping areas.
South of Point Reyes is Stinson Beach, where some shark attacks have been known to occur. This does not stop water lovers from riding the strong waves that come onto shore here. Whether you're going from North to South, the best way to experience the Northern California Coast is on Highway 1. This is a scenic drive that starts all the way up in Mendocino County and hugs the coast until you reach San Clemente, where it merges with Route 5.
A few hours up the coast is Mendocino County, which is an area many visitors to Northern California will visit on their California Coast travel. You can whale watch from the shore when migrating gray whales and the calves travel close to the California coast, right beyond where the waves emerge. You don't have to drive inland and go all the way to Willits to see giant redwoods, since there are plenty of them of the coast. The Avenue of the Giants is inland, but you can still see the same types of tress along certain stretches of the Northern California coast.
With museums, wineries, Redwood forests, wildlife watching and hiking opportunities, a California Coast vacation can hardly be called boring. While the empty beaches and lack or tourist infrastructure will keep many away, hardy travelers that appreciate simple living appreciate the quaint little towns and windswept, deserted beaches.
Just south of Mendocino, the Little River area has sights you should not miss. Fern Canyon is a popular place to visit. It is inside the 1,831 acres of Van Damme State Park. You can dive for abalone or simply enjoy the scenic hike on the ten miles of trails that takes you through a canyon carpeted in green ferns, and along the beach.
You can stay in a bed and breakfast and spend your days wandering on the beach, camp and hike, go golfing at the Little River Inn, or simply enjoy a relaxed weekend curled up in front of a fire at you own vacation rental on the coast. A California coast vacation is a scenic, invigorating trip that will inspire and delight you.

Rob Pursey:
DJ Mark The 45 King was perhaps (with the exception of Marley Marl) the first producer I remember just wanting to own all the records that he'd produced, remixed or had a hand in. The simple, hard hitting loops of some of his early classics coupled with the fact that all the MCs he worked with – Lakim Shabazz, Chill Rob G, Latee, Markey Fresh, Latifah etc. – all had the kind of flawless, commanding flows that just demanded you listen, mean that to this day it's hard to compare his music to anyone's and as a resul just have a '45 King zone' in my brain. Seeing him get his huge paydays later in his career with 'Hard Knock Life' and 'Stan' was perhaps, to me, one of the most rewarding stories in rap history, but this mix is definitely about that late 80s/early 90s zone that he just dominated for me. However, loving pretty much every damn record he produced, this had to be a Part 1 of sorts, as I could never have included all the gems that he committed to wax. Hell I even missed out my personal favourite 'Court Is Now In Session' just so I'd have to do another! Anyway, enjoy some of the most unheralded, but dopest rappers in history (along with a couple of well-known legends of course) over that classic Mark The 45 King sound. More dusty than digital – enjoy!

What is so damned fascinating about The DaVinci Code?
I just finished listening to Dan Brown's The DaVinci Code and I can't help but shake my head and wonder:
Why the hell is this book so damned popular?
Dan Brown is a dreadful writer.  Not just mediocre. But bad. Really bad.  I mean really, let's open with an evil albino? Why not just have a midget and a one armed man as villains? Dear Lord.
And the code stuff? They are riddles, not codes.
And the ending. Dreadful.  Truly dreadful.

Warty Visitor
Well, this evening I was staring out the door into the darkness to see if our sometimes-feral cat Scrappy wanted to be let in for some additional kitty chow, and I found this little guy peering in instead. He's a good sized frog, probably three or four inches in length (just the body, not the legs), and he stood still as I tried to catch several pictures of him through the glass. I tried to get some motion video of his little chin pulsing, but it didn't really turn out with the 1/2 second exposure times. Still, he's kind of cute.
I mean, for a warty, slimy amphibian.
I'll move him off into the bushes so the cat doesn't get him when he comes back.
Boing Boing: Google logo redesigned by Students for Free Tibet
I usually don't post links to Boing Boing stuff, since everybody in the known universe already reads Boing Boing, but I thought this logo design for Google by the Students for a Free Tibet warranted a bit wider distribution.
Sorry Google, but if your motto is to "don't be evil", you are seriously off course. If your motto is "don't be evil, except when there is a large, potentially lucrative market for us to exploit as long as we hold our noses and pretend that we aren't evil", then you are a lot closer.

What I know and don't know about Asterisk…
Well, I haven't got it all figured out yet, but here is what I know:
- It's not hard to compile asterisk for the amd64, but...
- You need to be careful compiling the ztdummy kernel module: in particular, you must define USE_RTC when compiling, because the sourcefile incorrectly only checks for USE_RTC if __i386__ is defined, which is not the case for 64 bit machines.
- Getting mpg123 to compile seems hopeless on the amd64.
- You can get a phone number for $11/month, with unlimited incoming calls and about $.02 a minute for outgoing calls to the United States via VoicePulse Connect!.
- I can, with a minimum of effort, create a simple dialplan that allows incoming calls from that number to be forwarded to some phones attached to my hacked Linksys PAP2 adaptor.
- BestBuy has a nice 5.8 ghz phone on sale for $25 with a $10 rebate.
- I can make calls from my Linux console (using a headset) to those phones.
What I don't know:
- While the phones attached to the PAP2 can receive calls, I haven't figured out how originate calls from them. There is obviously something stupid about configuring them that I don't understand.
- Sometimes the voice quality from the console seems bad, which I suspect is some kind of codec mismatch.
Ultimately, I'd like to make a simple "dialplan compiler" that allows you to enter some basic information, (account numbers, logins and the like) and generates the necessary asterisk configuration files. I'll probably write it in Python...
Hopefully, I'll have this up and ready for human testing in the next week or so. Then, I'll unveil the deeper purpose! Stay tuned.
Monday Malais
Well, I'd hoped to announce the results of some of my experimentation with Asterisk, but the weekend didn't conspire with me very well. My mom ended up in the hospital (she's back out, but it was worrisome) and I was nursing a borderline migraine most of the weekend. Yesterday I ate most of a pound of chocolate M&Ms (first time I've done that in two years, ever since I started Weight Watchers) and was generally not very pleasant to be around. Today, I feel like crap, but it's back to the sugar mines of
Pixar Disney...
I'm glad Mom's out of the hospital and feeling better, but Mondays still suck.

Athletics pick up former White Sox 1B, Frank Thomas
The A's pick up White Sox veteran Frank Thomas for a one year deal. He gets a guaranteed $500,000, plus up to $2.6 million in bonuses if he says healthy through the season. The White Sox cast the veteran adrift in 2005 because of his injuries. That's really the big question: will we get the Frank Thomas that played 153 games in 2003 and batted .271 with 87 runs, or the Frank Thomas of 2005 that played only 34 games and had only 19 runs?
One thing I know: I'll be watching. 🙂

Sushi Eating HOWTO
I must admit: I love sushi. Even basic nigiri and sashimi show a degree of concentration that we don't often see in the west.  Precision. Freshness. Balance. Everytime I have a meal of good sushi, I can't help but feel better. The flavors of fish, rice, soy, wasabi and gari are all just... I love it. I've grown to appreciate it so much that it now seems very strange to cook certain fish like salmon.
That being said, I'm no expert: I've never been to Japan and the only Japanese words I know come from menus. Â But like most things, the more you know, the more you enjoy the subtlety of it all, so I'll just provide this link to the informative and useful Sushi Eating HOWTO.
My new PC…
Over the last couple of months, I had gradually decreased the number of computers in my office to just two (well, computers that have X86 architecture anyway), and I decided that I would like to have a new amd64 based machine. I priced out the cost of just building one from components, and found that I probably couldn't do better than the HP a1310n, so I just went out and bought one. I've purged the windows infestation off it, and installed Fedora Core 4 on it. I've got a number of projects that can benefit from its high speed, including goofing around with MythTV and Asterisk. I got the ivtv driver working on my WinTV PVR150 MCE card and even have accelerated X running on it, so progress is being made. Last night I had some difficulty with Asterisk, the ztdummy driver that provides timing information seems not to load for reasons that escape me. But the hardware seems to be quite nice, I only wish the onboard video had NTSC outs, then this machine would be ideal as a front end for MythTV.

Go ahead and vote for republicans and several more years of trickle down economics as these retardicans give their corporate owners more money to create jobs as our rich overlords. Then watch as they roboticize their operations and get rid of even more of us and blame it all on the other party. Trickle down can not work in the modern robotics era. Don't you wonder how our nations productivity, GDP, and prices keep going up even as fewer and fewer of us are employed. It is trickle down tax policies where we are forced to give all our cash to the wealthiest to enslave us and then to remove us completely. I may be gotten rid of, but I shall not vote for my own removal and be forced to finance my own removal from the rolls of living wage earners. Please wake up and know lies when you hear them and at least as you see them acted on.

You should take your own advise and realize that Odumbass hasn't got a friggin clue as how to create jobs,He's never had one to start with..
And thanks to his dumbass policies the Middle East is in turmoil..
He thinks Letterman is more important than Israel basically throwing them under the bus..
He's nothing but an arrogant show boat that needs took down a notch or two..
That will happen in November,Hate to see you lose your Gov. check(NOT)but I prefer to keep my freedom..

You can thank Bill Clinton for alot of job losses,Crystal Tissue,Techno-Trim,just to name a couple(NAFTA)North American Free Trade Act...
