Study of Photometric Variability of Selected SU UMa Dwarf Novae

In this work we present time-resolved photometry of several poorly-studied dwarf novae during recent superoutbursts. Observations were made with a CCD, mounted on 50- and 60-cm telescopes of the Sternberg Astronomical Institute in Crimea in April - May and October 2012 and June - July 2013. Superhumps were detected in light curves of all the dwarf novae. The amplitudes and periods of detected light variations were calculated. Superhumps evolution was also followed up for all systems and classification is improved

Morphological and Physiological Characteristics of the Representatives of Melilotus Albus and Melilotus Officinalis, Growing on the Territory of Kalmykia

A comparative analysis of leaf blades of two kinds of clover (Melilotus albus, Melilotus officinalis) growing on the territory of Kalmykia has been carried out. Identified diagnostic features in the anatomical structure of the leaves of each species. The parameters of leaf tissue are set. The results of the work give an idea of the degree of plasticity of a characteristic of a leaf plate of two types of clover. Demonstrated features of plates of the same species can be equally, as well as specific for this species, and adaptive variability, due to which the plant has adapted to life in arid conditions. The water regime, indicators of transpiration and productivity of the clover were studied. Changes in physiological parameters were determined before the onset of the summer drought and at its height. The established morphological and physiological characteristics of the two species of clover allow them to be defined as plants that are well adapted to growing under the arid conditions of Kalmykia. The combination of the structural features of the clover with its physiological capabilities, valuable feeding properties and a positive effect on the soil, testifies to the effectiveness of the use of clover in the lean, saline areas of the region. The obtained data can be used in further systematic studies of the genus Melilotus, as well as in planning reclamation measures

Scientific rationale of ingredients choice for functional fish pastes

In recent years, the global demand for finished fish products is increased. Aquaculture raw materials are a rich source of nutrients for health. At the same time a large amount of fished fish raw materials are rejected and representing a losses. High-quality raw materials with technological defects are not in demand by the food production of fish products. Perishable substandard fish raw materials can be used in the production of combined fish products. The analysis of the fish catches global scale in the seas, oceans, farmed marine and freshwater aquaculture is carried out. An assessment of the market trends for the production and fish products consumption is made. This article provides an overview of targeted ingredient selection for balanced fish formulations. The characteristics of the most popular plant origin ingredients and their derivatives in the fish pates production are given. A comprehensive assessment of the biological, energy and nutritional value of plant products is given. Described technological approaches and production methods, the safety of vegetable ingredients. The results of research, technological solutions, substantiation of the choice of ingredients adopted by the developers for the formulations of multicomponent pate are summarized. The use of unclaimed raw materials, leftover fish meat with plant ingredients represents additional profit. Fish pate formulations are the basis for the production of complete, ready-to-eat products. Tests of multicomponent fish and vegetable products confirm their high performance. Pates, balanced in nutritional value, minerals, are a finished product that does not require additional preparation. The review article will generate awareness among the researchers, food technologists for the production of fish products and the general public

Concepts "health" and "illness"in an approach to mathematical modeling

At assistance to the population the modern medicine offers traditionally specialized approach: all known nosological forms are incorporated in groups of the diseases which treatment is carried out by narrow experts. At a similar approach it is impossible to define a state of health of each person, as uniform multidimensional open system. Therefore, it is impossible to create the mathematical model, allowing to diagnose and predict a human body condition. The terminology offered in work gives the chance a complete system approach to understanding of system of interaction of different types of 'illness'. On the basis of this terminology it is possible to come nearer to creation of mathematical model of forecasting of a condition of a human body.При оказании помощи населениюсовременная медицина предлагает традиционно специализированный подход: все известные нозологические формы объединены в группы заболеваний, лечение которых осуществляют узкие специалисты. При подобном подходе невозможно определить состояние здоровья каждого человека, как единой многомерной открытой системы. Следовательно, невозможно создать математическую модель, позволяющую диагностировать и прогнозировать состояние организма человека. Предложенная в работе терминология даёт возможность целостного системного подхода к пониманию системы взаимодействия разных видов «нездоровья». На основании данной терминологии возможно приблизиться к построению математической модели прогнозирования состояния организма человека

Condition somatic and stomatologic health of pregnant women

The modern medicine has sufficient demonstrative base to draw a conclusion, children born at mothers with the complicated course of pregnancy and ekstragenitalny diseases statistically authentically have the congenital pathology, early the acquired diseases leading to an invalidizatsiya and restriction of work capacity more often. The effective organization of inspection of the female population since the birth will give the chance to reduce, on the one hand, intensity of pathology, with another - to reduce weight of a current and probability of emergence of exacerbations of diseases. From the economic point of view prevention is less expensive, than treatment of caries and its complications.Современная медицина располагает достаточной доказательной базой для того, чтобы сделать вывод: дети, рожденные у матерей с осложненным течением беременности и экстрагенитальными заболеваниями статистически достоверно чаще имеют врожденную патологию и рано приобретаемые заболевания, приводящие к инвалидизации и ограничению трудоспособности. Эффективная организация обследования женского населения с рождения даст возможность, с одной стороны, снизить интенсивность патологии, с другой - уменьшить тяжесть течения и вероятность возникновения обострений заболеваний. С экономической точки зрения профилактика является менее затратной, чем лечение кариеса и его осложнений

A long term spectroscopic and photometric study of the old nova HR Del

The Nova HR Del, discovered in 1967, was found to be exceptionally bright in the optical and UV during the whole lifetime of the IUE satellite (ending in 1996) and appears to be still extremely luminous today. The reason for this continuing activity is not clear; continuing weak thermonuclear burning might be involved. HR Del was thus monitored over several years, both in broad band photometry and spectroscopically in the H$\alpha$ spectral region. The profile of the H$\alpha$ line shows two components: a narrow, central component; and broader wings. The former is most easily understood as being due to an accretion disk, whose geometry might lead to it partly occulting itself. That component shows something like an S wave with an orbital phase dependance, suggesting that it could be due to a spot bright in H$\alpha$. The wide component must come from another region, with a probably non-negligible contribution from the material ejected during the 1967 outburst. Non-orbital variations of the H$\alpha$ equivalent width were found both on long and short time scales. Similar variations were found in the photometry, showing a component with a clear dependence on the orbital phase, but no obvious relation with the H$\alpha$ variations. The orbital part of the photometric variations can be explained by irradiation of the companion, while the properties of H$\alpha$ are explicable by the presence of an accretion disk and a spot bright in H$\alpha$.Comment: 12 pages, 15 figures, accepted for publication in Astronomy & Astrophysic
