Refrigeration science and technology proceedings---Sovutgich fanlari va texnologiyasi

In this paper, the evaporation of water droplets in two-phase steam compression processes and its influence on heat pump COP were analyzed. The results showed that the initial diameter of liquid particles greatly influences the cooling effect. This is because in the case of larger droplets, vapor condenses on the droplets to raise their temperature, and the droplets grow before evaporation. In these cases the quality of the two-phase steam decreases as compression advances, and so the cooling effect by evaporation does not work well. This growth of droplets is more remarkable for liquid particles of larger diameter and for higher speed of compression. Liquid particles of 10 um in diameter or less will increase the COP even in high-speed compression processes such as 50 rps (3000 rpm) in the compression cycle. ---Ushbu maqolada ikki fazali bug 'siqish jarayonlarida suv tomchilarining bug'lanishi va uning issiqlik nasosining COP ga ta'siri tahlil qilindi. Natijalar shuni ko'rsatdiki, suyuqlik zarralarining boshlang'ich diametri sovutish effektiga katta ta'sir qiladi. Buning sababi shundaki, kattaroq tomchilar bo'lsa, bug' tomchilarda ularning haroratini oshirish uchun kondensatsiyalanadi va tomchilar bug'lanishdan oldin o'sadi. Bunday hollarda ikki fazali bug'ning sifati siqilish kuchayishi bilan pasayadi va shuning uchun bug'lanish orqali sovutish effekti yaxshi ishlamaydi. Tomchilarning bu o'sishi kattaroq diametrli suyuqlik zarralari va yuqori siqilish tezligi uchun ko'proq e'tiborga loyiqdir. Diametri 10 um yoki undan kam bo'lgan suyuqlik zarralari COPni yuqori tezlikda siqish jarayonlarida ham oshiradi, masalan, siqish siklida 50 rps (3000 rpm) kabi.

Exploding the computer myth.Discovering the 13 Realities of High Performing Business Systems---KOMPYUTER AFSONASINI PORTLASH Yuqori samarali biznes tizimlarining 13 haqiqatini kashf qilish

The Computer Myth states that automation's benefits are auto- matic, that computers are inherently a smart business investment that is likely to improve operations, reduce costs, or both. If this were true, organizations would be enjoying performance gains- revenues, earnings, cost savings, faster time-to-market, new products-proportional to their massively increased expendi- tures on Information Technology (IT). But they aren't. The Computer Myth isn't true, not by a long shot. It's a dangerous misconception that leads businesses to waste billions of dollars each year. Automation only benefits com- panies with a deep understanding of its true costs, limitations, capa- bilities, pitfalls, and requirements. Most organizations have not yet developed such an understanding, and it is costing them dearly. This book is for any business person who has to deal with computer systems. ---Kompyuter afsonasida aytilishicha, avtomatlashtirishning afzalliklari avtomatikdir, kompyuterlar aqlli biznes sarmoyasi bo'lib, operatsiyalarni yaxshilash, xarajatlarni kamaytirish yoki ikkalasini ham amalga oshirishi mumkin. Agar bu to'g'ri bo'lsa, tashkilotlar daromadlar, daromadlar, xarajatlarni tejash, bozorga tezroq kirish, yangi mahsulotlar - Axborot texnologiyalari (IT) ga bo'lgan katta o'sish xarajatlariga mutanosib ravishda foyda ko'rar edi. Lekin ular emas. Kompyuter haqidagi afsona haqiqatga to'g'ri kelmaydi, uzoqdan emas. Bu xavfli noto'g'ri tushuncha bo'lib, korxonalar har yili milliardlab dollarlarni isrof qilishiga olib keladi. Avtomatlashtirish faqat uning haqiqiy xarajatlarini, cheklovlarini, imkoniyatlarini, tuzoqlarini va talablarini chuqur tushunadigan kompaniyalarga foyda keltiradi. Aksariyat tashkilotlar hali bunday tushunchani ishlab chiqmagan va bu ularga qimmatga tushadi. Ushbu kitob kompyuter tizimlari bilan shug'ullanishi kerak bo'lgan har qanday ishbilarmonlar uchundir.

Polymer Chemistry an introduction

This book is intended as an introductory text for a course in polymer chemistry at the ad- vanced undergraduate or beginning graduate level. It should also serve as an introduction to the field for the industrial chemist with no prior training in polymer chemistry, or as a ref- erence source for the practicing polymer chemist. I assume that students using this book will have completed undergraduate courses in organic and physical chemistry and will be famil- iar with the more commonly used spectroscopic and chromatographic methods of analysis and characterization. Ushbu kitob polimerlar kimyosi kursi uchun bakalavriat yoki magistratura bosqichi uchun kirish matni sifatida mo'ljallangan. Bundan tashqari, u polimer kimyosi bo'yicha oldindan tayyorgarlik ko'rmagan sanoat kimyogari uchun sohaga kirish yoki amaliyotchi polimer kimyogari uchun mos manba sifatida xizmat qilishi kerak. O'ylaymanki, ushbu kitobdan foydalangan talabalar organik va fizik kimyo bo'yicha bakalavriat kurslarini tugatadilar va tahlil va tavsiflashning ko'proq qo'llaniladigan spektroskopik va xromatografik usullari bilan tanishadilar.

Mirror for humanity: A Concise Introduction to cultural Anthropology.---Insoniyat uchun oyna: Madaniy antropologiyaga qisqacha kirish

Like other Overture Books, Mirror for Humanity (MFH) is intended to provide a concise, relatively low-cost introduction to a field, in this case cultural anthropology. This book may also work wel in a quarter system, if traditional cultural anthropology texts have proved too long for a one-quarter course.Conrad Kottak appreciates comments about his textbook from professors and students. ---Boshqa Overture kitoblari singari, "Insoniyat uchun ko'zgu" (MFH) ham bir sohaga, bu holda madaniy antropologiyaga qisqacha, nisbatan arzonroq kirishni ta'minlash uchun mo'ljallangan. Agar an'anaviy madaniy antropologiya matnlari choraklik kurs uchun juda uzoq bo'lsa, bu kitob chorak tizimda ham yaxshi ishlashi mumkin. Konrad Kottak o'z darsligi haqidagi professor-o'qituvchilar va talabalar tomonidan bildirilgan fikrlarni qadrlaydi

Modern food microbiology---Zamonaviy oziq-ovqat mikrobiologiyasi

This fifth edition of Modern food microbiology places specials emphasis on foodborne microorganisms, as the previous four editions attempted to do. A good understanding of the basic biology of foodborne organisms is more critical for food scientists now than in previous decades. ---Zamonaviy oziq-ovqat mikrobiologiyasining ushbu beshinchi nashri, avvalgi to'rtta nashrda bo'lgani kabi, oziq-ovqat mikroorganizmlariga alohida e'tibor beradi. Oziq-ovqat bilan ta'minlangan organizmlarning asosiy biologiyasini yaxshi tushunish hozirgi vaqtda oziq-ovqat olimlari uchun oldingi o'n yilliklarga qaraganda muhimroqdir.
