thank you very very much for your help!

Thank you very much!
How would you translate: türlü denemeler yapacak olanlara açıklamalarda bulunuyordu. ?

thank you again!

These are sentences I can't understand. Can someone translate them? Please!

Kimileyin, işte böyle Ingilizce tek sözcükle anlatırdı istediğini.

actually I don't understand only one word: kimileyin. Is this an imperative form from kimilemek? But I couldn't find the word kimilemek... If this is that English word, which is said in the following part of the sentence, I can't get it. Or maybe the the Inglish word mentioned in the sentence is "Pes" - it is said in a dialogue, before the sentence I wrote. If so, I still have no idea what can "kimileyin" mean.
And the second sentence:
Değişik ısılı ortamda, asitler, yağlar, et suyu içinde, türlü denemeler yapacak olanlara açıklamalarda bulunuyordu.

I have doubts especially about the last part, and I'm not sure what "et suyu" can mean. Is this some kind of serum, like blood serum or something?

and the last sentence:
Göz servisi, tam ve örnek bir bilim araştırma merkezi haline gelmişti.
in what meaning is this "tam ve örnek..."?

Hakan,Gökhan/Gökan, Hasan, Cem...

you do very well, wonderfull.

Erdinc! Thank you very much!

The biggest problem is that, in comparizon, not every version is the same. When I listen to Turks talking, they use those forms as they want to and every time as it is written in grammar...
so zorunda olmak means have to but also must, but gerek has the same meaning... is one of them stronger?

if I were with you
bir kimsenin yanında olmak not necessarly means to be next to somebody, but also be with someone (in one place)

Thank you very much KIVILCIM for the explanation!

so, can somebody explain to me:
is mecbutiyetinde olmak or mecbur olmak more like gerek/gerekiyor or more like lazim?
Actually I thought that gerek and lazim is exchangable...
is that true that zorunda kalmak is the strongest among them?
If so, is it something like have to?
