# Azerbaijani/Contents (Latin)/Lesson One - Greetings

Salam! Birinci dərsinizə xoş gəlmişsiniz! If you're wondering what that meant, it means Hello! Welcome to your first lesson!. Read on to learn more interjections.

## Greetings

Hello! - Salam ələyküm!, or Salam! for short!
Note that if someone says the former greeting, you must say the following back:
Hello! - Ələyküm salam
How are you? - Necəsiniz (formal), Necəsən (informal)
I'm fine, thanks. - Yaxşıyam, sağ olun.
And this is invariably followed by:
And you? - Bəs siz?
To which you can reply:
Thank you (very much). - Çox sağ olun.
After making a new Azeri friend, it would be rude not to say the following (and there are two ways of saying it):
Nice to meet you. - Məmnun oldum. / Çox şadam.

### Greetings at different times of the day

Good morning! - Sabahınız xeyir! (formal), Sabahın xeyir! (informal)
Good afternoon! - Gün aydın!
Good evening! - Axşamınız xeyir! (formal), Axşamın xeyir! (informal)
Good night! - Gecəniz xeyir! (formal), Gecən xeyir! (informal)

## Goodbyes

Goodbye! - Sağ olun!
See you! - Görüşərik!
See you (on Monday)! - (Bazar ertəsi günü) görüşənədək!

## When put into context...

Aysel: Salam ələyküm! Mənim adım Ayseldir.
Tural: Ələyküm salam, Aysel! Mən Tural.
Aysel: Necəsiniz, Tural?
Tural: Yaxşıyam. Bəs siz?
Aysel: Yaxşıyam, çox sağ olun.
Tural: Yaxşı. Tanış olduğumuza məmnun oldum.
Aysel: Mən də məmnun oldum.
Tural: Sağ olun!
Aysel: Görüşənədək!

### Translation

Aysel: Hello! My name is Aysel!
Tural: Hello, Aysel! I'm Tural.
Aysel: How are you?
Tural: I'm good. And you?
Aysel: I'm very good, thank you.
Tural: Good. Nice to meet you.
Aysel: Nice to meet you too.
Tural: Goodbye
Aysel: See you!

## Notes

In Azerbaijani, as is true with many other languages, when you're talking to someone you've never met before/rarely ever talk to/worthy of respect, you refer to them in the plural form. As you can see in the conversation, rather than referring to each other as sən (you [singular]), they refer to each other as siz (you [plural]). This is only a formality, but very important.
Another thing to note is that they rarely use the word mən (I) when referring to themselves. In Turkish, as long as the reader/listener can understand who the writer/speaker is talking about, words such as mən, sən, o (he/she), etc., don't need to be used.
Also, when Tural says "Mən Tural" (meaning "I'm Tural, but literally "Me Tural"), it's just like in Tarzan, when Tarzan goes "Me Tarzan, you Jane". In Azerbaijani, this is considered to be normal, because the copula ("to be" in English) is considered redundant.

# Azerbaijani/Contents (Latin)/Number
## Number

The Plural is formed from the Singular by the addition of lar after hard vowels (a, ı, o, u) or lər after soft ones (ə, e, i, ö, ü). Ex.:
* dəyənək stick: dəyənəklər sticks.
* pişik cat: pişiklər cats.
* körpü bridge: körpülər bridges.
* qapı door: qapılar doors.
* qohum relative: qohumlar relatives.
# Complex Analysis/Appendix/Proofs/Triangle Inequality

Let $z$ and $w$ be complex numbers. Since we have:
    $|z+w|^{2}\,$ $=(z+w){\overline {(z+w)}}=(z+w)({\bar {z}}+{\bar {w}})$ $=|z|^{2}+z{\bar {w}}+{\overline {z{\bar {w}}}}+|w|^{2}$ $=|z|^{2}+2{\mbox{Re }}(z{\bar {w}})+|w|^{2}$ $\leq |z|^{2}+2|z||w|+|w|^{2}$ $=(|z|+|w|)^{2}\,$
the triangular inequality follows after taking the square root of both sides. Note here we used the properties:
    ${\mbox{ Re}}(z)\leq |z|$, $|z|=|{\bar {z}}|$ and $z+{\bar {z}}=2{\mbox{Re }}(z)$.
Also, the induction shows:
    $\left|\sum _{1}^{n}z_{k}\right|\leq \sum _{1}^{n}|z_{k}|$
# Complete Guide to Starwarsology/Chapter Three: Media/Cinema and TV

Since 1977, various films and television productions set in the Star Wars universe have been released, starting with the original film Star Wars.

## Theatrical films
### Original trilogy

The original trilogy is the middle chapter of the so-called "Skywalker saga", and has been first released between 1977 and 1983, though its films had several alterations through the years (beginning with the mono mix print of Star Wars, released circa one month after the stereo version) from which it greatly differed, especially for the 1997 Special Editions and the 2004 DVD releases.

#### Star Wars (retitled "Star Wars Episode IV: A New Hope" in 1981)

Star Wars is the first film in the saga, written and directed by George Lucas, produced by Gary Kurtz (though the 1997 Special Edition is produced by Rick McCallum, who also produced the prequel films), shot in 35 mm by Gilbert Taylor. The film was first released on 25 May, 1977 in the United States as a Dolby or mono mix 35 mm or 6-tracks 70 mm film by 20th Century Fox.

#### Star Wars Episode V: The Empire Strikes Back

The Empire Strikes Back is the second film in the saga, directed by Irvin Kershner, and produced by Gary Kurtz (though like Star Wars, the Special Edition was produced by Rick McCallum). It was written by George Lucas.

### Star Wars Episode VI: Return of the Jedi

Return of the Jedi is the third film produced in the saga. It takes place after Episode V:The Empire Strikes Back and before Star Wars: The Force Awakens. It was written by George Lucas, with Lawrence Kasdan.

# Complex Analysis/Appendix/Proofs/Theorem 1.1

We prove that a set ${\mathfrak {G}}\subset \mathbb {C}$ is closed if and only if it contains all of its limit points.
We assume that ${\mathfrak {G}}$ contains all of its limit points and we show that its complement is open. Let $z_{0}\in \mathbb {C} -{\mathfrak {G}}$. Then, since $z_{0}$ is not a limit point of ${\mathfrak {G}}$, there is a ball $B_{\delta }(z_{0})$ that contains no point of ${\mathfrak {G}}$, that is $B_{\delta }(z_{0})\subset \mathbb {C} -{\mathfrak {G}}$. Since this is true for all $z_{0}\in \mathbb {C} -{\mathfrak {G}}$, it follows that ${\mathfrak {G}}$ is closed.
We now assume that there is a limit point of ${\mathfrak {G}}$ in $\mathbb {C} -{\mathfrak {G}}$ and show that ${\mathfrak {G}}$ is not closed. Let $z_{0}\in \mathbb {C} -{\mathfrak {G}}$ be a limit point of ${\mathfrak {G}}$. Then There is no neighborhood of $z_{0}$ that is contained in the complement of ${\mathfrak {G}}$, and therefore ${\mathfrak {G}}$ is not closed.

# EverQuest/Strategies/fearkiting

Fear kiting is a strategy which requires certain prerequisites to be available to the player or group deploying it. Firstly, and obviously, is access to one of the fear lines of spells. Secondly, a snare of some sort since otherwise the mobs will run out of range and the loot/XP will not be obtained. Thirdly some form of DOT (damage over time), either in the form of a spell or a pet beating on the mob, which will ensure the mob in question continues to die. Classes which have access to all these attributes and which can perform this operation solo include: shadowknights and necromancers.
Typically the mob to be fear kited is pulled with a snare, feared, and dotted. The process of fearing and damaging is repeated until the mob dies, snare being refreshed when necessary.

Graffe: http://www.graffe.com/spells.php?level=52#
short summary: In order to get this spell, you must provide an NPC (Utandar Rizndown in the OT for evil chars or Barnal Flamehand in FV for good ones) with one of the following spell scrolls (just hand in one at the time)
* Atol's Spectral Shackles

* Pillar of Frost
which in turn rewards you with either
* Abscond
* Tishan's Discord
* Thunderbold
* Tears of Solusek.
usefullness:
* helps losing aggro when in trouble, while staying in the same zone (no need to run/port back to faroff places like i.e. the grey)
* makes sometimes travel a bit easier, e.g. in OoT, when quadding the cyclops. bind at SE corner of island, and when bags are full, abscond back to traders. then gate back to Isle.
Tips for completing the quest:
* Barnal Flamehand is in the very eastern part of FV
* check if you can buy the turnin spells (atols etc.) in the bazaar. sometimes they go for 20 pp and less
* some of the spiders in FV (the caster type) do aggro, although green con
* Thunderbold is the spell which you'll get most times, abscond usually 1 out of maybe 8 turnins.
# EverQuest/uncommon Spells Tomes Discs

This page deals with the questing and creating of spells (for casters and hybrids) and tomes/discs (melee classes and hybrids). Please refrain from listing common spells, as we are not able to replace Lucy really....
Spells
Spells can be labeled as many things depending on their use, present form, or availiblity. All spells start as an item (in the form of a scroll)that has to be bought, looted, or merely given to a character that is of sufficent class and level to use it.
There is a large market within Everquest that deals with finding and selling uncommon spells to those spellcasters that still need them.
But after a spellcaster, either arcane or divine, gets one of these needed scrolls, it can be 'learned' which changes it from an item into a tool, used by the caster in exchange for various amounts of their Mana.
Tomes/Discs
Tomes are the melee/hybrids "spells". they range from damage multipliers/mitigators to resist improving and lots more.

# Chemical Sciences: A Manual for CSIR-UGC National Eligibility Test for Lectureship and JRF/Triple quadrupole mass spectrometer

A triple quadrupole mass spectrometer is a tandem mass spectrometer consisting of two quadrupole mass spectrometers in series, with a (non mass-resolving) radio frequency (RF) only quadrupole between them to act as a collision cell for collision-induced dissociation. The first (Q$_1$) and third (Q$_3$) quadrupoles serve as mass filters, whereas the middle (q$_2$) quadrupole serves as a collision cell. This collision cell is an RF only quadrupole (non-mass filtering) using an inert gas such as Ar, He or N$_2$ gas to provide collision-induced dissociation of a selected precursor ion that is selected in Q$_1$. Subsequent fragments are passed through to Q$_3$ where they may be filtered or scanned.

## Structural mass spectrometry

This alignment of two mass spectrometers in succession with a collision cell (e.g. a collision quadrupole) in between allows structural mass spectrometry to be performed. For example, the Q$_1$ may be set to select an ion of a known mass, which is fragmented in q$_2$. The third quadrupole (Q$_3$) is then set to scan the entire m/z range, giving information on the sizes of the fragments made. From the ion fragmentation information, the structure of the original ion can be deduced.

## History

The arrangement of three quadrupoles was first developed by Morrizon of LaTrobe University, Australia for the purpose of studying the photodissociation of gas-phase ions. The first triple-quadrupole mass spectrometer was developed at Michigan State University by Enke and Yost in the late 1970's.

# Chemical Sciences: A Manual for CSIR-UGC National Eligibility Test for Lectureship and JRF/Transverse relaxation optimized spectroscopy

Transverse relaxation optimized spectroscopy (TROSY) is an experiment in protein NMR spectroscopy that allows studies of large molecules or complexes.
The application of NMR to large molecules is normally limited by the fact that the line widths generally increase with molecular mass. Larger molecules have longer rotational correlation times and consequently shorter transverse relaxation times (T$_2$). In other words, the NMR signal from larger molecules decays more rapidly, leading to line broadening in the NMR spectrum and so poor resolution.
In an HSQC spectrum in which decoupling has not been applied, peaks appear as multiplets due to J-coupling. Crucially the different multiplet components have different widths. This is due to constructive or destructive interaction between different relaxation mechanisms. Typically relaxation for large proteins at high magnetic field strengths the transverse (T$_2$) is dominated by the dipole-dipole (DD) mechanism and the chemical shift anisotropy (CSA) mechanism. As the relaxation mechanisms are generally correlated but contribute to the overall relaxation rate of a given component with different signs, the multiplet components relax with very different overall rates. The TROSY experiment is designed to select the component for which the different relaxation mechanisms have almost cancelled, leading to a single, sharp peak in the spectrum. This significantly increases both spectral resolution and sensitivity, both of which are at a premium when studying large and complex biomolecules.
This approach significantly extends the molecular mass range that can be studied by NMR, but it generally requires high magnetic fields to achieve the necessary balance between the CSA and DD relaxation mechanisms; CSAs scale with field strength, while dipole-dipole couplings are field-independent.
