Компостларни Сурхондарё вилояти тупроқлари унумдорлиги ва ғўза ҳосилдорлигига таъсири

Фосфогипс билан ўтказилган тажриба натижалари, унинг узоқ йиллар давомида кўрсатган таъсирини (последействие) ўрганиш шуни кўрсатадики, ФГ ни оптимал меъёрларда қўллаш тупроқнинг сув-физикавий, физик-кимёвий, агрокимёвий хоссалари ва мелиоратив ҳолатини, қисқа вақт (2-3 йил) ичида яхшилайди, ўсимликлар физиологик ҳолатига ижобий таъсир кўрсатади, экинларнинг ғўзанинг ўсиши ва ривожланишига мақбул шароит яратади.

Mathematics

After focusing on numbers and their symbols, my quest continued from the four fundamental rules of arithmetic to calculus and its culmination in differential equations. Along the way, I delved into algebra, the theory of functions, geometry, trigonometry, hyperbolic functions, and analytic geometry, and also followed trails to number theory, symbolic logic, set theory, Boolean algebra, transfinite numbers, topology, fractals, vector analysis, and probability theory. My draft text was later polished with the help of distinguished professional mathematicians, linguists, and historians. In its final form, I hope this format of mathematics and its history will appeal to readers who have, or would like to develop, a fondness for mathematics.

Mathematics as Problem Solving

Frontispiece reproduces the front cover of the original edition. It was designed by my later father Yuri Soifer, who was a great artist. Will Robinson, who produced a documentary about him for the Colorado Springs affiliate of ABC, called him “an artist of the heart.” For his first American one-man show at the University of Colorado in June–July 1981, Yuri sketched his autobiography: I was born in 1907 in the little village Strizhevka in the Ukraine. From the age of three, I was taught at the Cheder (elementary school by a synagogue), and since that time I have been painting. At the age of ten, I entered Feinstein’s Jewish High School in the city of Vinniza. The art teacher, Abram Markovich Cherkassky, a graduate of the Academy of Fine Arts at St. Petersburg, looked at my book of sketches of praying Jews, and consequently taught me for six years, until his departure for Kiev. Cherkassky was my first and most important teacher. He not only critiqued my work and explained various techniques, but used to sit down in my place and correct mistakes in my work until it was nearly unrecognizable. I couldn’t then touch my work and continue – this was unforgettable.

500 crohet stitches: The ultimate crochet stitch bible

500 Crochet Stitches is both a stitch guide and a how-to-crochet primer, all in one volume. You get all the information needed to get started, including how to choose yarn and needles, read patterns, work basic stitches, how to check gauge, increase and decrease, join pieces and finish projects and care for your crochet items. The comprehensive pattern library includes 500 crochet stitches, including basic stitches using single and double crochet, trebles, and some new techniques to get the fabric you want for that special sweater or hat. Lace and openwork stitches are a starting point for exploring the airy shawls, and afghans crochet is famous for. Use one of the many motifs to create an heirloom blanket, or mix and match motifs to create a truly unique piece. There are also edgings and trims you can use on your crochet and other projects, including sewn items and knitted ones. Each is fully explained with instructions and accompanied by a full-color photo of a sample crocheted swatch. All swatches are worked in updated yarns, beautifully photographed and accompanied by easy-to-follow instructions.

Workbook in Higher Algebra

The present set of notes was developed as a result of Higher Algebra courses that I taught during the academic years 1987-88, 1989-90 and 1991-92. The distinctive feature of these notes is that proofs are not supplied. There are two reasons for this. First, I would hope that the serious student who really intends to master the material will actually try to supply many of the missing proofs. Indeed, I have tried to break down the exposition in such a way that by the time a proof is called for, there is little doubt as to the basic idea of the proof. The real reason, however, for not supplying proofs is that if I have the proofs already in hard copy, then my basic laziness often encourages me not to spend any time in preparing to present the proofs in class. In other words, if I can simply read the proofs to the students, why not? Of course, the main reason for this is obvious; I end up looking like a fool.

MATHEMATICAL FOUNDATIONS OF ELASTICITY

There are three things that every beginner in elasticity theory should know. The first is that "Kirchhoff" has two h's in it. The second is that Hooke's law will not be found as a basic axiom (it "really" means you are working with the linearized theory). The third is that rese?rchers in elasticity theory are very opinionated, even when they are wrong. During our own work in this field we have refused to fight, and in keeping with this pacifist approach, we now issue these general disclaimers: This book is neither complete nor unbiased. Furthermore, we have not mentioned many deep and highly erudite works, nor have we elucidated alternative approaches to the subject. Any historical comments we make on subjects prior to 1960 are probably wrong, and credits to some theorems may be incorrectly assigned. Excellent historical sketches are available in the works of Truesdell [1968], Sokolnikoff [1956], and Sneddon [1980] cited in the bibliography.

The William Lowell Putnam Mathematical Competition 1985–2000

This book is the third collection of William Lowell Putnam Mathematical Competition problems and solutions, following [PutnamI] and [PutnamII]. As the subtitle indicates, the goals of our volume differ somewhat from those of the earlier volumes. Many grand ideas of mathematics are best first understood through simple problems, with the inessential details stripped away. When developing new theory, research mathematicians often turn to toy† problems as a means of getting a foothold. For this reason, Putnam problems and solutions should be considered not in isolation, but instead in the context of important mathematical themes. Many of the best problems contain kernels of sophisticated ideas, or are connected to some of the most important research done today. We have tried to emphasize the organic nature of mathematics, by highlighting the connections of problems and solutions to other problems, to the curriculum, and to more advanced topics. A quick glance at the index will make clear the wide range of powerful ideas connected to these problems. For example, Putnam problems connect to the Generalized Riemann Hypothesis (1988B1) and the Weil Conjectures (1991B5 and 1998B6).

Mathematical Olympiad Challenges

Working mathematicians often tell us that results in the field are achieved after long experience and a deep familiarity with mathematical objects, that progress is made slowly and collectively, and that flashes of inspiration are mere punctuation in periods of sustained effort. The Olympiad environment, in contrast, demands a relatively brief period of intense concentration, asks for quick insights on specific occasions, and requires a concentrated but isolated effort. Yet we have found that participants in mathematics Olympiads have often gone on to become first-class mathematicians or scientists and have attached great significance to their early Olympiad experiences.
