U.S.A. MATHEMATICAL OLYMPIADS, 1972-1986

The New Mathematical Library (NML) was started in 1961 by the School Mathematics Study Group to make available to high school students short expository books on various topics not usually covered in the high school syllabus. In a decade the NML. matured into a steadily growing series of some twenty titles of interest not only to the originally intended audience, but to college students and teachers at all levels. Previously published by Random House and L. W. Singer, the NMI became a publication series of the Mathematical Asso- ciation of America (MAA) in 1975. Under the auspices of the MAA the NML continues to grow and remains dedicated to its original and expanded purposes. In its third decade, it contains some thirty titles.

Беда ўсимлиги ҳосилдорлигига ўриш муддатлари таъсири ва унинг иқтисодий самарадорлиги

Ҳозирги вақтда суғориладиган ерлардан олинаётган беда уруғи жуда кам, тахминан республика бўйича гектарига 1,0 центнерни ташкил этади. Бунга уруғлик беда агротехник тавсияларга риоя қилинмаётганлиги, хўжаликларда уни устига-устак ва кичик-кичик майдонларга экилаётганлиги, чанқатиб қўйилаётганлиги ёки сув, шунингдек, зарпечак ва бошқа ёввойи ўтларга бостириб юборилаётганлиги, зараркунандалар ва касалликлар билан зарарланишининг олди олинмаётганлиги, беда гулларини чанглатувчи ҳашаротлар деярли йўқлиги сабаб бўлмокда.

TIPS REGARDING UPSC CSE PREPARATION

It is necessary to cover the syllabus thoroughly from such reference books and revise them regularly. A UPSC aspirant’s preparation should always be revision friendly. If you are reading a reference book, either underline important points in the book only or make short notes. So that the next time you are able to cover the same topics in much lesser time. Aspirants should also solve lots of practice papers. The best source is previous years’ UPSC papers. Apart from CSE prelims, objective papers of CAPF, CDS exams conducted by UPSC can also give good idea about the kind of questions asked by UPSC. The aim should be to develop the ability to attempt optimum number of questions keeping in mind the negative marking system. In prelims, I used to attempt the easier questions first and then go for questions where I had to guess or spend some more time. In many questions, even if you don’t know the exact answer, you can guess it by eliminating some options. To develop this judgment, the aspirant should practice regularly.

Изучение лирических произведений в школе.

ЎЗБЕКИСТОН РЕСПУБЛИКАСИ ИҚТИСОДИЙ-ИЖТИМОИЙ ТАРАККИЁТИНИНГ МУСТАҚИЛЛИК ЙИЛЛАРИДАГИ (1990-2010 ЙИЛЛАР) АСОСИЙ ТЕНДЕНЦИЯ ВА КУРСАТКИЧЛАРИ ҲАМДА 2011-2015 ЙИЛЛАРГА МЎЛЖАЛЛАНГАН ПРОГНОЗЛАРИ

Мамлакатимиз бундан йигирма йил олдин ўз мустақиллигини эълон қилиб, тарихий тараққиётининг янги босқичига қадам қўйди. Бу йиллар давомида босиб ўтган мураккаб, шу билан бирга, шарафли йўлимизга назар ташлар эканмиз, Ўзбекистоннинг ўтган давр мобайнида иқтисодий ва ижтимоий ривожланиш борасида эришган марра ва натижаларини холисона баҳолаш зарурати мавжуд эканини англаймиз.

MATH LEARNING WHEELS

Math Wheels are a fun-filled interactive alternative to flash cards and worksheets that present math facts in a game format that children love. Because they invite children to take skill-building into their own hands, Math Wheels are a powerful learning tool you and your students will enjoy using again and again. Each engaging shape is designed to complement popular classroom themes. What’s more, because the wheels are self-correcting (all students have to do is flip the moving answer-hider to reveal the solution), they offer children instant feedback. And, if a child does miss a problem, a turn of the wheel provides a fresh opportunity to try again. Some of the wheels are interchangeable (Plus, Minus and Times) so if, for example, you are doing a dinosaur unit, you can enhance the unit by pairing the dinosaur shape with the problem wheel that addresses the math skill of your choice.

Фермер хўжаликларида сувдан самарали фойдаланиш йўллари

Менинг битирув малакавий ишимни асосий мақсади фермер хўжаликларида сувдан самарали фойдаланиш ҳамда сувни тежаш, қишлоқ хўжалик экинларига ўз вақтида керакли миқдорда етказиб бериш вазифаларни ўрганишдир.

Такрорий экин сифатида экилган кунгабоқарнинг “Наврўз” нави ҳосилдорлигига минерал ўғитлар меъёрининг таъсири

Республикамиз иқлим шароитида мойли ўсимликлар (кунгабоқар, кунжут, ерёнғоқ, махсар) парваришлаш ва уни етиштириш технологияси етарли даражада ўрганилмаган. Шуни ҳисобга олиб Ўзбекистон мойли ва толали экинлар тажриба станциясида Бутунжаҳон коллекцияси асосида кунгабоқарнинг юқори мой бериш хусусиятига эга бўлган нав намуналарини танлаш, шу асосда Ўзбекистон шароитида етиштириб, ундан юқори ҳосил олиш учун парваришлаш технологиясини ишлаб чиқиш устида дастлабки илмий тадқиқотлар олиб борилмоқда.

TREASURE ISLAND

Livesey, and the rest of these gentlemen having asked me to write down the whole particulars about Treasure Island, from the beginning to the end, keeping nothing back but the bearings of the island, and that only because there is still treasure not yet lifted, I take up my pen in the year of grace 17__ and go back to the time when my father kept the Admiral Benbow inn and the brown old seaman with the sabre cut first took up his lodging under our roof. I remember him as if it were yesterday, as he came plodding to the inn door, his sea-chest following behind him in a hand-barrow—a tall, strong, heavy, nut-brown man, his tarry pigtail falling over the shoulder of his soiled blue coat, his hands ragged and scarred, with black, broken nails, and the sabre cut across one cheek, a dirty, livid white.

Toeplitz and Circulant Matrices: A review

In this tutorial report the fundamental theorems on the asymptotic behavior of eigenvalues, inverses, and products of “finite section”Toeplitz matrices and Toeplitz matrices with absolutely summable elements are derived. Mathematical elegance and generality are sacrificed for conceptual simplicity and insight in the hopes of making these results available to engineers lacking either the background or endurance to attack the mathematical literature on the subject. By limiting the generality of the matrices considered the essential ideas and results can be conveyed in a more intuitive manner without the mathematical machinery required for the most general cases. As an application the results are applied to the study of the covariance matrices and their factors of linear models of discrete time random processes.
