Mostly due to bathing or washing clothes our finger become wrinkled what was the reason behind it??
I found an explanation for my question here , which suggests that water washes out sebum (special oil, which covers our skin) and water gets into outer layer of now unprotected skin by osmosis. This article also suggests that fingers are not really shriveled - they are water-logged. But is this right? I think I observed many times my wrinkly fingers after swimming, but I never felt that they are water-logged. Any thought on this matter would be highly appreciated.
How much money do I need to show as proof of support when applying for a UK Standard Visitor visa? I am an Indian citizen studying in Italy on an Italian visa that expires 19 November, 2015. I have permesso di soggiorno. I want to visit the United Kingdom for my vacations for a week during March. I know the procedures already, however I am a little bit confused about the amount that I must show as a proof of support with my bank statements. I will stay for a week with my friends who are also students in Italy and will be in London for 5 days. What would be the amount in Euros that I need to show for my visit to UK? Finding square root without using sqrt function? I ask this Question on behalf of my neighbor.   Their 12 year old son saw his parents having sex.  As there is only one room in their home we can't say its the parents' mistake... but now the question is how do they handle the situation? I am from Europe, and I did an internship in the US (California) in 2015. When filing my 2015 taxes, I ended up having to pay some small difference for the federal taxes, but got a refund on my state taxes, of roughly $1.6k. That was all the income I had in the US in 2016.  I did not enter the US in 2016 at all.  I managed to figure out that I don't need to file any California tax forms for 2016 (source: ) but I am not sure about federal taxes.  I tried researching the problem, and got some information on it, but the situation is still a bit unclear. It seems that since I listed my state tax as an itemized deduction in my 2015 tax report, which I filed in 2016, the state refund I got in 2016 is, in fact, taxable.  In this situation, would I have to file my taxes (and possibly pay owed tax) for 2016, even though I never set foot in the US in that year, and my total income is just $1.6k? How do you handle multiple instances of setTimeout()? What is the most recommended/best way to stop multiple instances of a setTimeout function from being created (in javascript)?  An example (psuedo code):  function mouseClick() {    moveDiv("div_0001", mouseX, mouseY); }  function moveDiv(objID, destX, destY) {    //some code that moves the div closer to destination    ...    ...    ...     setTimeout("moveDiv(objID, destX, destY)", 1000);    ...    ...    ... }   My issue is that if the user clicks the mouse multiple times, I have multiple instances of moveDiv() getting called.  The option I have seen is to create a flag, that only allows the timeout to be called if no other instance is available...is that the best way to go?  I hope that makes it clear.... If you have two envelopes, and ... Can I just fit a cassette with more gears with the same derailleur? I've got a Boardman Road Sport which I use for commuting and doing reasonable length rides during the week etc. I have Shimano Claris as my rear derailleur and so is some of my groupset. I would like to upgrade my cassette to an either 9 or 10 speed to give me a greater variety of gears. To do this do I need to change my rear derailleur from 8 speed to Shimano 105 or something similar? Or can I just change my cassette? Do I also need to change my shifters as well? In a 2-columned document, how do you get a table to stretch across the entire width? I'm working on a document that runs two columns of text down the page, like many scientific conference proceedings.  However, I'd like for a table to run across the entire width of the page, as it is far too wide to fit into one column.  How do I do this? In unix/linux, any number of consecutive forwardslashes in a path is generally equivalent to a single forwardslash. eg.  $ cd /home/shum $ pwd /home/shum $ cd /home//shum $ pwd /home/shum $ cd /home///shum $ pwd /home/shum   Yet for some reason two forwardslashes at the beginning of an absolute path is treated specially. eg.  $ cd ////home $ pwd /home $ cd /// $ pwd / $ cd // $ pwd // $ cd home//shum $ pwd //home/shum   Any other number of consecutive forwardslashes anywhere else in a patch gets truncated, but two at the beginning will remain, even if you then navigate around the filesystem relative to it.  Why is this? Is there any difference between /... and //... ? href to an image label - how to jump to the image instead of the caption below the image? How do I summon the Golem? Show that holomorphic $f_1, . . . , f_n $ are constant if $\sum_{k=1}^n \left| f_k(z) \right|$ is constant. I am looking at some code and it has this statement:    ~ConnectionManager() {     Dispose(false); }   The class implements the IDisposable interface, but I do not know if that is part of that the tilde(~) is used for. How to prevent different checksums for different typesets Add "Delete with reason" button/dialog to existing moderator tools for flagged answers While this is an old problem, it's one that will only increase with time.  As Stack Exchange sites gain in popularity, more and more users are coming to the sites in search of answers to their specific problems.  Unfortunately, not all of them understand the basic operating principals behind Stack Exchange, and ask questions, or start discussions as separate answers.  Deleting these answers is fine, but more often (I would argue almost always) than not, a new user doesn't understand why.  Granted, comments are a way of doing this, but there are drawbacks to comments:   They require extra, replicated effort on the part of the moderator for something that they do repetitively The message will be inconsistent; messages like this would be consistent, cite the relevant resources that guide the user in the right direction The larger size would have a higher chance of grabbing the user's attention, as well as put more weight behind the action (as it's officially attached to the answer in a consistent manner). The banner will serve as an example of what not to do to other users who can see the deleted post.   Additionally, there are tools that can help with auto-commenting on posts, but these have their drawbacks as well:   Not all moderators use these tools The messages that are delivered by the tools are ultimately generated initially by the moderators, so the message will not be consistent These tools are not always available on other devices (e.g., mobile platforms)   It would be helpful to the user if they had a reason indicating why the answer was deleted.  Something along the lines of:    In order to accomplish this, I propose an additional (not a replacement) button in the moderation tools labeled "delete with reason".  Mods would still be able to delete answers outright, they just have the option now of stating why in an easy manner which will allows for more time to moderate harder.  Placement is not important (screen real estate is valuable, yes), but I envision it looking something like this in the moderator tools:    When clicking "delete with reason", a dialog, much like the "close" dialog will appear with options:    Initial options for the reasons could be:   Asking a new question Starting discussion   A mechanism like this has the potential for other benefits as well:   Users with an answer deleted with a reason might actually be directed to perform the right action now, and in the future (creating better site denizens) Users who wish to contest the deletion of an answer on meta can cite that specific reason, which mods can specifically address (which actually might reduce noise on meta about "why was my answer deleted?") Can reduce flags on answers asking "why was this deleted?" (admitted, I've not personally experienced this to be a pervading problem on Stack Overflow, but this might be the case for other mods on other Stack Exchange sites) Other Stack Exchange sites which don't have that many users will give a better experience to their users when their first action isn't ideal for a Stack Exchange site; this will enhance the chance that the site will retain the user and get good contributions from them (as per Farseeker's comments: , ).   Additionally, if this works well for the moderator tools, I imagine that it would not be such a leap to eventually have this graduated to users with the rep to cast delete votes, thus allowing non-mods to deliver a more clear message to new users about how to best participate on a Stack Exchange site. I have bought return tickets from London to Lille Europe on Eurostar. The trains on my outward and inbound journeys both stop at Calais Frethun.  Will Eurostar let me get on in Calais on the inbound? What about getting off at Calais on the outbound leg? I suspect leaving the train early is easier than getting on the train 'late'. Prove that $\sum^{n}_{r=0}(-1)^r\cdot \large\frac{\binom{n}{r}}{\binom{r+3}{r}} = \frac{3!}{2(n+3)}$ Prove that $\displaystyle \sum^{n}_{r=0}(-1)^r\cdot \large\frac{\binom{n}{r}}{\binom{r+3}{r}} = \frac{3!}{2(n+3)}$   $\bf{My\; Try::}$ We can write $$\frac{\binom{n}{r}}{\binom{r+3}{r}} = \frac{n!}{r!\times (n-r)!}\times \frac{r!\times 3!}{(r+3)!} = \frac{3!\times n!}{(n-r)!\times (r+3)!}$$  So our sum is $$ 3!\sum^{n}_{r=0}(-1)^r\frac{n!}{(n-r)!\times (r+3)!} = \frac{3!}{(n+1)(n+2)(n+3)}\sum^{n}_{r=0}(-1)^r\frac{(n+3)!}{(r+3)!\times (n-r)!}$$  So we get Sum $$ \frac{3!}{(n+1)(n+2)(n+3)}\sum^{n}_{r=0}(-1)^r\binom{n+3}{r+3} = -\frac{3!}{(n+1)(n+2)}\sum^{n}_{r=0}(-1)^{r+3}\binom{n+3}{r+3}$$  $$  = -\frac{3!}{(n+1)(n+2)(n+3)}\left[-\binom{n+3}{3}+\binom{n+3}{4}-\binom{n+3}{5}--.......+(-1)^{n+3}\binom{n+3}{n+3}\right]$$  $$=-\frac{3!}{(n+1)(n+2)(n+3)}\left[\binom{n+3}{0}-\binom{n+3}{1}+\binom{n+3}{2}-\binom{n+3}{3}+\binom{n+3}{4}-\binom{n+3}{5}--.......+(-1)^{n+3}\binom{n+3}{n+3}\right]+\frac{3!}{(n+1)(n+2)(n+3)}\left[\binom{n+3}{0}-\binom{n+3}{1}+\binom{n+3}{2}\right]$$  So we get $$ = \frac{3!}{(n+1)(n+2)(n+3)}\left[1-(n+3)+\frac{(n+3)(n+2)}{2}\right] = \frac{3!}{(n+1)(n+2)}\times \frac{n^2+3n+2}{2} = \frac{3!}{(n+1)(n+2)(n+3)}\times \frac{(n+1)(n+2)}{2} = \frac{3!}{2(n+3)}$$  Can we prove it Using Combinatorial way,bcz above method is very lengthy  If yes then plz explain here  Thanks A novel where a woman from "future" of 1999 speaks leet-speak Maybe I'm searching for the wrong thing, but I can't see how I can do this.  I have two servers:   Server A (has SQL Server 2012 installed) Server B (has SQL Server 2014 installed)   Server A provides an API via IIS. The code both inserts and gets data from the database depending on the API call.  Server B does exactly the same for its local database.  I would like to have it so that the two databases are consistent copies of each other. I do believe this is what HA accomplishes.   So a load balancer, for example, might direct API calls to A sometimes, and B sometimes, but the data needs to be consistent either way.  I found some documentation on HA for SQL Server 2012, but not on how to do this for a mixed environment of 2012 and 2014.  Any help or pointers to documentation would be great! Thanks.
