I am travelling by emirates from India to Dubai (DXB) and after 8 hour layover  I will be boarding an emirates flight to the USA from DXB airport.  Do I need a transit visa for the layover period in Dubai?
Do I need a transit visa for a layover via airports in the UAE, such as Dubai International Airport or Abu Dhabi International Airport? If so, what are the requirements for such a visa? Can I get the transit visa on arrival?
I think some good words would be conflicted, or confused. As an example of context, think of someone who believes in freedom of speech, but, at the same time, they would support banning comedians who make jokes about certain issues that person cares about. Modified files in a git branch are spilling over into another branch Doesn't Radagast care about trees? In the book The Two Towers, Treebeard refers to Gandalf as "the only wizard that really cares about trees".  But in Fellowship of the Ring, we met the wizard Radagast the Brown, whose special focus is on animals, especially birds.  Of course, animals aren't trees, but it is difficult to imagine a person loving animals without also caring deeply about trees - especially when that person loves birds most of all, and so many birds are so  dependent upon trees for their survival.  More generally, Radagast seems like an all-around nature lover, and this too suggests that he "really cares about trees".  This leads me to imagine several possibilities:   Treebeard doesn't know Radagast (this seems unlikely - they have both been around for thousands of years, so surely they have bumped into each other at some point)   Treebeard forgot about Radagast, possibly because he was annoyed at Saruman and a bit angry at the time    Radagast actually doesn't care about trees    Is there some other alternative I have overlooked, or is one of the options I mentioned correct?  Or does Tolkien never address this apparent problem? I don't understand how quantum mechanics (and therefore also quantum computers) can work  given that while we work with quantum states, particles that this quantum state consist of cannot be observed, which is the most fundamental requirement.  If I am not mistaken, by "observed" we mean interaction with any other particle (photon, gluon, electron or whatever else). So my very important questions:   Aren't the particles this quantum state consists of interacting with each other? Why doesn't that cause the state to collapse? Aren't all particles in the universe interacting with Higgs field and gravitons etc? Why doesn't that cause every quantum state to collapse?   I feel there is something very fundamental in quantum mechanics that I am not aware of, hence I would be very pleased to have these questions answered. Strange bar plot alignment in Pandas Why is SQL Server losing a millisecond? I have a table structured like this:  CREATE TABLE [TESTTABLE] (     [ID] [int] IDENTITY(1,1) NOT NULL,     [DateField] [datetime] NULL,     [StringField] [varchar](50),     [IntField] [int] NULL,     [BitField] [bit] NULL )   I execute the following code:  BEGIN     INSERT INTO TESTTABLE (IntField, BitField, StringField, DateField)     VALUES ('1', 1, 'hello', {ts '2009-04-03 15:41:27.378'});       SELECT SCOPE_IDENTITY()   END   And then   select * from testtable with (NOLOCK)   and my result shows:  2009-04-03 15:41:27.*377*   for the DateField column.  Any ideas why I seem to be losing a millisecond?? What is $\Delta t$ in the time-energy uncertainty principle?

Customizing the output of Compass sprites How to best encapsulate monetary values in a database Let $f:R\rightarrow R$ be a function such that all its successive derivatives exist in all $R$ and also $f(x)f''(x)\leq 0$ everywhere.  If $\alpha$ and $\beta$ be two successive roots of $f(x)=0$.   Then prove that $f'''(x)=0$ for atleast one $\gamma \in(\alpha,\beta)$.  My Attempt:  I began by taking an example $f(x)=(x-1)(2-x)$ and let $x=1$ and $x=2$ be its two successive roots.The statement is trivially true.  Then I took the function $f(x)=e^{-x}(x-1)(2-x)$.The statement is true here also so on and so forth.  But what would be the exact proof I wonder. It appears to be a question of Rolle's Theorem. I'm using Windows 7 as the host machine with VMWare Workstation 9. I created a virtual machine Ubuntu Desktop 12.04 LTS 64 bit version. There are two options for log in, Ubuntu and Ubuntu 2D. Whenever I log in to Ubuntu, the task bar will not show up, is like having a black margin all around the desktop background and only the center is visible.  I wish I could attached a pic, but I need at least 10 reputation.  When I move my mouse over the left side of the desktop I can see that something is there but it is shown only as a black square. I tried deleting the virtual machine I created for Ubuntu and re-installed it, but it keeps appearing like that.  When I switched to log in with the Ubuntu 2D version everything worked alright. I could see the task bar, the icons, the clock etc. What might be causing this problem?

Cropping the exact same part of several pictures I have several pictures that are exactly the same except for some small variations.

Generalized Fresnel integral $\int_0^\infty \sin x^p \, {\rm d}x$ I am stuck at this question. Find a closed form (that may actually contain the Gamma function) of the integral  $$\int_0^\infty \sin (x^p)\, {\rm d}x$$  I am interested in a Laplace approach, double integral etc. For some weird reason I cannot get it to work.   I am confident that a closed form may actually exist since for the integral:  $$\int_0^\infty \cos x^a \, {\rm d}x = \frac{\pi \csc \frac{\pi}{2a}}{2a \Gamma(1-a)}$$  there exists a closed form with $\Gamma$ and can be actually be reduced further down till it no contains no $\Gamma$. But trying to apply the method of Laplace transform that I have seen for this one , I cannot get it to work for the above integral that I am interested in.   May I have a help?
