European science review

Abstract. Genotyping of H.pylori from the region of Aral Sea, a zone of ecological disaster with a high prevalence of gastric cancer, was compared with Tashkent – region with low gastric cancer rate. PCR analysis revealed that 66,1% samples from the Aral Sea and 84.2% samples from Tashkent was CagA positive. In Tashkent, we found the prevalence of VacAs1 m2 alleles and VacAs1 m1 alleles from Khorezm region. In most samples from Khorezm had mixed genotype of IceA1/IceA2 (80%), whereas in Tashkent mostly IceA1 allele was distributed. The predominant genotypes in high-risk of gastric cancer area (Aral Sea) were cagA+/vacAs1m1/iceA1/iceA2 and in low-risk Tashkent, the district was cagA+/vacAs1m2/iceA1, which correspond to the less aggressive strains. Comparison of H.pylori virulence genes distributed in high- and low-risk area of gastric cancer in Uzbekistan showed the differences between genotypes, more aggressive form of H.pylori was revealed in the Aral Sea region.

The Decree of the President of the Republic of Uzbekistan PD-1875 as of 10 December 2012, “On Measures on Further Improvement of Teaching of Foreign Languages”, was the essence of the country’s reforms in the field of foreign language learning. Since the adoption of the system-generating decree all the work in this area has been intensified and major reforms in modernization of teaching foreign languages at all levels of continuous education have started. According to the targets set by the Government of the Republic, new State Educational Standards, based on international experience - CEFR were adopted. In 2013, on the initiative of the Ministry of Higher and Secondary Specialized Education of the Republic of Uzbekistan the work on developing a set of learning materials for foreign languages meeting international requirements has been launched. A group of English language teachers from all over the Republic developed truly innovative language learning manual that meets newly established requirements.

Anatomy of Flowering Plants

Understanding plant anatomy is not only fundamental to the study of plant systematics and palaeobotany, but is also an essential part of evolutionary biology, physiology, ecology, and the rapidly expanding science of developmental genetics. In the third edition of her successful textbook, Paula Rudall provides a comprehensive yet succinct introduction to the anatomy of flowering plants. Thoroughly revised and updated throughout, the book covers all aspects of comparative plant structure and development, arranged in a series of chapters on the stem, root, leaf, flower, seed and fruit. Internal structures are described using magnification aids from the simple hand-lens to the electron microscope.

ФИЗИОЛОГИЯ РАСТЕНИЙ: ДЫХАНИЕ РАСТЕНИЙ

Важным элементом в подготовке специалиста с высшим образованием является самостоятельная работа студентов с учебным материалом. Современные образовательные технологии ориентированы на привитие у обучаемого навыков самостоятельного поиска необходимой для учебы информации, её усвоения, постановки и решения задач, самоконтроля уровня своей подготовленности по изучаемой дисциплине. При этом студенту предоставляется право формировать в определенных пределах свою образовательную программу

Вторая часть учебника, являясь продолжением первой части, изданной в 1999 г., посвящена изложению базовых схем преобразователей постоянного напряжения в по- стоянное, постоянного – в переменное (автономные инверторы), переменного напряже- ния в переменное напряжение неизменной или регулируемой частоты. Материал также структурирован в соответствии с принципом «четыре в одном» по четырем уровням доступности изложения: два уровня для «неспециалистов» по силовой электронике и два уровня для «специалистов» по силовой электронике. Основным методом анализа энергетических характеристик преобразователей является прямой метод.

ФИЗИОЛОГИЯ РАСТЕНИЙ

Рост и развитие растений. Стратегии существования растений и животных отличны. Животные независимы и активны, растения автотрофны и ведут прикрепленное существование. Они не неподвижны, но фиксированы в пространстве. Отсюда вытекает следующая стратегия: растения четко отслеживают внешние факторы и избирательно подстраиваются под них. Рост и развитие растений - процессы, в которых она тоже будет прослеживаться. На уровне клетки, на каждом этапе развития растения различаются. В клетке три генома, они взаимодействуют, это достаточно сложно. Клеточная стенка и пластиды - особые структуры

Plant Stress Physiology, 2nd Edition

Stress is a common aspect in the life cycle of a plant. However, the principles of ‘plant stress’ remain poorly defined, and key terminology can be interpreted in more than one way. This ambiguity can potentially impede scientific progress. Several theoretical frameworks detailing the principles of plant stress have been conceived, based on analogies with human stress, mechanics and thermodynamic states. Particularly important are the concepts of eustress and distress (good and bad stress), and how these are affected by stressor dose and duration. Using these concepts can help place experimental data in a conceptual framework, and avoid generation of seemingly contradictory data.

Plant Physiology

The fields of biological and medical physics and biomedical engineering are broad, multidisciplinary and dynamic. They lie at the crossroads of frontier research in physics, biology, chemistry, and medicine. The Biological and Medical Physics, Biomedical Engineering Series is intended to be comprehensive, covering a broad range of topics important to the study of the physical, chemical and biological sciences. Its goal is to provide scientists and engineers with textbooks, monographs, and reference works to address the growing need for information. Books in the series emphasize established and emergent areas of science including molecular, membrane, and mathematical biophysics; photosynthetic energy harvesting and conversion; information processing; physical principles of genetics; sensory communications; automata networks, neural networks, and cellular automata. Equally important will be coverage of applied aspects of biological and medical physics and biomedical engineering such as molecular electronic components and devices, biosensors, medicine, imaging, physical principles of renewable energy production, advanced prostheses, and environmental control and engineering.

Plant Physiology

With this Third Edition, the authors and contributors set a new standard for textbooks in the field by tailoring the study of plant physiology to virtually every student—providing the basics for introductory courses without sacrificing the more challenging material sought by upper-division and graduate-level students.
