FIZIKAVIY TADQIQOT USULLARI

Darslikda fizikaviy tadqiqot usullarining asosiy turlari, ularning yaratilish tarixi, nazariyalari barcha kimyoviy birikmalarni tuzilishi va xossalarini o'rganish imkoniyatlari bayon qilingan. Darslik hozirgacha an'anaviy tarzda bayon qilingan materiallardan farqli ravishda, fizikaviy tadqiqot usullari o'nta bobda oddiylikdan murakkablikka o'tish tartibida yoritilgan. Har bir bob reja, tayanch atamalar, asosiy material, nazorat savollari, masala va mashqlar hamda tavsiya qilingan adabiyotlar ro'yxati bilan yakunlanadi.

ҚАДИМГИ ТУРКИЙ ТИЛ

Олтой назариясига кўра туркий тилларнинг, жумладан ўзбек тилининг тарихи, олтой тилларнинг қадимда бир тил бўлган олтой давридан бошланади. Тарихий ҳужжатларнинг йўқлиги сабабли бу давр иннг саналари номаълум, Олтой бобо тили дастлаб тунгус-манжур на тури-мўғул тилларига; турк-мўғул тили эса турк ва мўғул тилларига ажралган. Шундан сўнг туркий тиллар тарихида хун даври (мелоддан аввалги учничи асрдан мелоднинг тўртинчи асригача) бошланиб, туркий тиллар икки тармоққа шарқий ҳун ва ғарбий хун тилларига бўлинади. Туркий тиллар тарихида хун даврининг алоҳида кўрсатилишига ўша даврда Марказий Осиёдан Шарқий Европагача бўлган территорияни ишғол қилган хун хонлигининг вужудга келиб, кейинчалик унинг иккига ажралиши асос қилиб олинади.

KIMYODAN REAKSIYALAR, MODDALARNING NOMI VA FORMULALARI. OLIMLAR HAQIDA MA’LUMOT

Кimyogarlar kongresida yangi nomenklatura qabul qilindi. Jeneva nomenklaturasi bo’yicha moddalardagi asosiy zanjir no’merlanib, radikal nomining oldiga ushbu radikalning asosiy zanjirdagi qaysi uglerod atomiga brikkanligini ko’rsatuvchi raqam qo’yiladi.1960-yilda IUPAC (International) Union of Pure Applied Chemistry)-IYPAK (sof va amaliy xalqaro ittifoqi) kamissiyasi tomonidan ishlab chiqilgan yangi nomenklatura e’lon qilindi.

ФИЗИЧЕСКАЯ КУЛЬТУРА В V — VIII КЛАССАХ

Все возрастающие требования к физическому воспитанию детей обязывают учителей школ тщательнее подбирать средства и методы, применяемые на уроках физической культуры в зависимости от местных условий и особенностей детского коллектива.

Architecture in Japan

Algo menor que el estado de California, Japón posee una población mucho mayor estimada en 127.417.244 habitantes según datos de julio de 2005. En la última década, el censo se ha incrementado en unos dos millones de personas aunque, en general, la sociedad japonesa está envejeciendo. De hecho en la ciudad mo- derna más grande del mundo, Tokio, que ocupa solo un 0,6% de la superficie total de Japón, viven un 10% de los japoneses, lo que supone una densidad nada des- preciable de 5.655 personas por kilómetro cuadrado. Buena parte del litoral oriental del país, entre Tokio y Osaka, es prácticamente un área urbana continua, mientras que el oeste es más montañoso y está menos poblado. Estos datos y, en especial, la densidad urbana del país, son importantes para comprender su arquitectura, sobre todo con relación a la construcción residencial. Otro factor decisivo para la arqui-

Basic fluid mechanics and hydraulic machines

Fluid mechanics is concerned with the behaviour of liquids and gases at rest and in motion. The proper understanding of mechanics of fluids is important in many branches of engineering: in biomechanics the flow of blood is of interest; ocean currents require a knowledge of fluid mechanics; chemical processing of plants require a thorough knowledge of fluid mechanics; aeronautical engineers require knowledge of flow of air over the aircraft to reduce drag and increase lift; mechanical engineers require knowledge of fluid properties to design pumps, water turbines, gas turbines and rockets; civil engineers require fluid mechanics to study river currents and erosion; and environmentalists require knowledge of fluid properties for solving pollution problems of air and water to control flood, irrigation channels, etc.

Civil engineering hydraulics

This book is designed to meet the special, but not exclusive, needs of civil engineering students reading for degrees and diplomas and for Engineering Council Parts I and II examinations at universities and colleges of higher education. Having as its main feature a substantial number of worked examples, its purpose is to augment lecture courses and standard textbooks on fluid mechanics and hydraulics by illustrating the application of the underlying theory to a wide range of practical situations. The inclusion of exercise problems, with answers, will enable students to assess their understanding of the theory and methods of analysis and design. Aspects of relevant theory, in concise form and accompanied by explanation, are included at the beginning of each chapter. The book should prove useful not only to students but also to practising engineers as a concise working reference.

The topkapi scroll-geometry and ornament in Islamic architecture

Drawings can reveal much about architectural practice and design methods, particularly when a building tradition lacks theoretical treatises; the Islamic architectural heritage is a case in point. In the premodern Muslim world references to archi- tecture were often embedded in a wide variety of nonarchitectural texts and "how-to" manuals providing simple instructions without theoretical elaboration.

Environmental Hydraulics of Open Channel Flows

Rivers play a major role in shaping the landscapes of our planet (Table P.1, Fig. P.1). Extreme flow rates may vary from zero in drought periods to huge amount of waters in flood periods. For example, the maximum observed flood discharge of the Amazon River at Obidos was about 370 000 m3/s (Herschy 2002). This figure may be compared with the average annual discharges of the Congo River (41 000 m3/s at the mouth) and of the Murray-Darling River (0.89 m3/s at the mouth) (Table P.1). Even arid, desertic regions are influenced by fluvial action when periodic flood waters surge down dry watercourses (Fig. P.1(a)).
