Transportation channels calculation method in MATLAB

Output devices and charged particles transport channels are necessary components of any modern particle accelerator. They differ both in sizes and in terms of focusing elements depending on particle accelerator type and its destination. A package of transport line designing codes for magnet optical channels in MATLAB environment is presented in this report. Charged particles dynamics in a focusing channel can be studied easily by means of the matrix technique. MATLAB usage is convenient because its information objects are matrixes. MATLAB allows the use the modular principle to build the software package. Program blocks are small in size and easy to use. They can be executed separately or commonly. A set of codes has a user-friendly interface. Transport channel construction consists of focusing lenses (doublets and triplets). The main of the magneto-optical channel parameters are total length and lens position and parameters of the output beam in the phase space (channel acceptance, beam emittance − beam transverse dimensions, particles divergence and image stigmaticity). Choice of the channel operation parameters is based on the conditions for satisfying mutually competing demands. And therefore the channel parameters calculation is carried out by using the search engine optimization techniques.Представлен пакет прикладных программ по проектированию каналов транспортировки, предназначенный для разработки магнитооптических каналов в среде широко распространённой системы MATLAB. Поскольку динамику заряженных частиц в фокусирующих каналах удобно записывать в матричной форме, то использование системы MATLAB, в которой объектом обработки информации является матрица, вполне обосновано. Комплекс программ обладает наглядным и удобным интерфейсом. Канал транспортировки строится из фокусирующих систем − дублеты и триплеты. Основными характеристиками магнитооптических каналов являются их полная длина и места расположения линз, а также параметры пучка в выходной плоскости канала (аксептанс канала, эмиттанс пучка − поперечные размеры пучка, расходимость частиц и стигматичность изображения). Выбор рабочего варианта параметров канала производится из условия удовлетворения взаимно конкурирующих требований, и поэтому расчёт параметров канала осуществляется с использованием методов поисковой оптимизации.Представлено пакет програм з проектування каналів транспортування, призначений для розробки магнітооптичних каналів у середовищі широко поширеної системи MATLAB. Оскільки динаміку заряджених часток у фокусуючих каналах зручно записувати в матричній формі, то використання системи MATLAB, в якій об'єктом обробки інформації є матриця, цілком обґрунтоване. Комплекс програм має наочний і зручний інтерфейс. Канал транспортування будується з фокусуючих систем − дублети і триплети. Основними характеристиками магнітооптичних каналів є їх повна довжина і місця розташування лінз, а також параметри пучка у вихідній площині каналу (аксептанс каналу, емітанс пучка − поперечні розміри пучка, розбіжність часток і стигматичність зображення). Вибір робочого варіанта параметрів каналу робиться з умови задоволення взаємно конкуруючих вимог, і тому розрахунок параметрів каналу здійснюється з використанням методів пошукової оптимізації

PORRIDGE — THE MAIN TYPE OF ADDITIONAL FOOD IN INFANTS

The balanced proper nutrition in infants is the one of the main factors of optimal children’s growth and development, and of their health forming. One of the leading types of additional food is cereal food stuffs — porridge. The choice of cereal food stuffs for infants must be held not only with the fact, that porridge is the source of complex carbohydrates, but that it is a source of protein, amino acids, microelements, vitamins, and dietary fibers.Key words: infants, additional food, cereals, amino acids, porridge.(Voprosy sovremennoi pediatrii — Current Pediatrics. 2009;8(4):116-120

MODERN PREBIOTICS IN CORRECTION OF INTESTINAL MICROBIOCENOSIS IN CHILDREN

This article presents a data of role of normal micro flora of gastrointestinal tract in forming of alimentary functions and immune system of newborn. Processes of formation of intestinal micro biocenose, and pre and postnatal factors of development of dysbacteriosis in children of early age were analyzed. Authors give modern classification of probiotics. Results of trials show effectiveness and safety of combination of probiotiс cultures Bifidobacterium lactis BB-12 and Streptococcus thermophilus, forming new complex «Bifiform Baby» for children of early age.Key words: children of early age, normal micro flora, gastrointestinal tract, probiotics.(Voprosy sovremennoi pediatrii — Current Pediatrics. 2009;8(2):109-113

The development of food preferences: anatomical and genetic determinants, important factors of taste development in children

I.N.&nbsp;Zakharova1, Yu.A.&nbsp;Dmitrieva1, E.B.&nbsp;Machneva2, A.N.&nbsp;Tsutsaeva3 1Russian Medical Academy of Continuous Professional Education, Moscow, Russian Federation 2Russian Children’s Clinical Hospital of the Pirogov Russian National Research Medical University, Moscow, Russian Federation 3Stavropol State Medical University, Stavropol, Russian Federation Since ancient times, scientists and philosophers were interested in the sense of taste, the mechanisms of its development, anatomical structures responsible for taste, and its importance. Currently, it is clear that food preferences are the main determinant of the development of nutrition and food behavior. Food preferences begin to develop in the early childhood and retain throughout the life. Therefore, inculcating correct nutritional behavior with respect to healthy food is a promising approach to improve the quality of diet being one of the key factors affecting human health. This article addresses current data on morphology, genetics, embryology, and ontogeny of gustatory system as well as major factors affecting the development of food preferences in a child. Most of these factors are modified ones, therefore, the aim of this review is to draw the attention of pediatricians since this is pediatrician who makes evidence-based recommendations on child nutrition and provide s adequate feeding strategy. Keywords: genetics, food preferences, taste, taste receptors, children, smell, ontogeny, tongue, baby food, healthy lifestyle.
