Lipolytic Effect

Investigating the effect of chloroform anesthesia on blood lipase, I found that the increase in the lipolytic effect of blood reaches a maximum eight hours after anesthesia, and then 9 hours, 10 hours 11 hours, 12 hours, 13 hours keeps on one and the same the same level; it remains at the same level in a day. MA Nimtsovitskaya and SM Schwartz, investigating, apparently, only three hours and 24 hours after anesthesia, misinterpreted the time of the appearance of the maximum effect they noticed. According to my research (J. Exp. Biol. And Med., 1926, No. 5) in cases of a short deep normally flowing anesthesia by the very end of the second day, there is a slight weakening of the increased effect, which also contradicts the authors' data a little.

Level Of Risk

The purpose of this paper is to develop a concept for managing the level of risk of disrupting the sustainable development of the enterprise. The research methodology is based on the system economic theory and the operational theory of risk management. A methodology is proposed for the study of the development and implementation of management decisions in the managerial subsystem, taking into account the identified risks of sustainable development of the enterprise at the intentional, expectational, cognitive and functional stages. Within the framework of these stages, the processes of goal setting, information collection, assessment of the existing environment and forecasting of changes in the enterprise, as well as the processes of implementing decisions are carried out. To shed light on the processes of identifying risk factors and developing appropriate anti-risk managerial impacts depend on the localization in the control object. When decomposing a control object, four types of localization are distinguished: an object subsystem, a process subsystem, a project subsystem, and an environmental subsystem. The implementation of managerial decisions, from the point of view of the object subsystem, can be limited by the high cost of the main production equipment and long life cycles of the finished product. When implementing the developed managerial solutions, there may be a redistribution of profit centers or a change in the way it is generated, which will lead to a change in the characteristics of the enterprise's process subsystem. In the project subsystem, an enterprise can achieve maximum effect by focusing its efforts on the introduction of innovative technologies. The speed of changes in the external environment of the enterprise becomes very high, so the role of forecasting the impact of these changes on the environmental subsystem of the enterprise increases, and applying this knowledge to develop managerial impact, on the one hand, and to adapt the enterprise to these changes, on the other. It is shown that by regulating and eliminating the imbalance in the preparation of managerial impacts, it is possible to reduce the level of risk in the implementation of such decisions.

В статье авторами рассматриваются особенности влияния криминальной субкультуры на преступность среди несовершеннолетних и молодежи, которая в последние годы в российском обществе известна под аббревиатурой «АУЕ». Правоохранительным органам современная криминальная субкультура «АУЕ» интересна главным образом потому, что она может оказывать влияние на криминальную обстановку в обществе. Исследуются причины и условия распространения криминальной субкультуры среди несовершеннолетних и молодежи. Негативное влияние криминальной субкультуры на преступность среди несовершеннолетних и молодежи связано, прежде всего, с тем, что она способствует формированию отрицательных свойств личности несовершеннолетнего, что, в свою очередь, становится базой для формирования преступного поведения. Особое внимание авторами уделяется вопросу популяризации криминальной субкультуры через сеть Интернет, что требует новых подходов к разработке предупредительных мер в отношении рассматриваемого феномена. In the article, the author examines the peculiarities of the influence of the criminal subculture on crime among minors and youth, which in recent years in Russian society is known by the abbreviation «AUE». The causes and conditions of the spread of the criminal subculture among minors and youth are investigated. Currently, modern technologies allow using minimal time and financial resources to get the maximum effect for criminals. The author pays special attention to the issue of popularization of the criminal subculture through the Internet, which requires new approaches to the development of preventive measures against the phenomenon under consideration. For law enforcement agencies, the modern criminal subculture «AUE» is interesting, first of all, in the quality in which it can influence the criminal situation in society. The negative impact of the criminal subculture on crime among minors and young people is primarily due to the fact that it contributes to the formation of negative personality traits of a minor, which in turn becomes the basis for the formation of criminal behavior. The peculiarity of the negative influence of the criminal subculture «AUE» is that it is considered such not only from the point of view of its social assessment, but also within a specific group: relations among minors and young people.

Kinematic Sensitivity

We perform the dimensional synthesis of a parallel manipulator to be used as a force-feedback device in a virtual reality application for surgeon training in prostate brachytherapy. For such brachytherapy operations, the characteristics of the required workspace point towards the architecture of the linear DELTA robot to be used as the force-feedback device to the surgeon. In this paper, we address the dimensional synthesis of the linear DELTA robot for the prescribed workspace. To this end, we propose the minimum relative kinematic sensitivity as an objective function, a kinematic performance index that is different from most of the commonly used metrics, i.e., manipulability and dexterity. The minimum relative kinematic sensitivity represents the ratio of the minimum to the maximum effect of a unity-bounded set of actuator displacements on the moving-platform pose. These extremum sensitivities are computed independently over the prescribed workspace. Thence, the dimensional synthesis problem consists in finding the robot dimensions that maximize the minimum relative kinematic sensitivity, so it is guaranteed within a narrow interval over the prescribed workspace. This optimization problem is nonconvex, which poses a challenge from the computational point of view. However, because of symmetry in the mechanism and other simplifications, the number of optimization variables is reduced to four. This allows a reasonably fine discretization of the search domain, giving the designers confidence that the ensuing local optimum is close to the global optimum.

This study shows that something commonplace, like heating in private households, is a complex social phenomenon. Technological developments, such as passive houses and smart heating controls, can only have their maximum effect on energy savings if they are socially adapted. How technology and action can be thought of together is explained in this work. It thus makes a contribution to social science climate research. Using the example of domestic heating, it conveys the theoretical and analytical efficiency of the practice approach and shows that this approach has great potential in investigating processes of change in social practices. For those who deal with the topic of heating or other forms of everyday energy consumption and its (political) framework conditions from a practical point of view, there are numerous hints as to how the complexity of everyday life can be addressed in practice.

The Impact

The term geo-sciences has been used here to include the disciplines geology, geophysics and geochemistry. However, in order to apply geophysics and geochemistry effectively one must begin with a geological model. Therefore, the science of geology should be used as the basis for lunar exploration. From an astronomical point of view, a lunar terrain heavily impacted with meteors appears the more reasonable; although from a geological standpoint, volcanism seems the more probable mechanism. A surface liberally marked with volcanic features has been advocated by such geologists as Bülow, Dana, Suess, von Wolff, Shaler, Spurr, and Kuno. In this paper, both the impact and volcanic hypotheses are considered in the application of the geo-sciences to manned lunar exploration. However, more emphasis is placed on the volcanic, or more correctly the defluidization, hypothesis to account for lunar surface features.

Potential Use

The origin of mica polytypes has long been a challenging problem for crystal- lographers, mineralogists and petrologists. From the petrological point of view, interest in this field arose from the potential use of layer stacking data to furnish further informations about equilibrium and/or kinetic conditions prevailing during the crystallization of the widespread mica-bearing rocks. From the compilation of previous experimental works dealing with the occurrence domains of the various mica "polymorphs" (1Mr, 1M, 2M1, 2M2 and 3T) within water-pressure vs temperature fields, it became clear that most of these modifications should be considered as metastable for a fixed mica species. Furthermore, the natural occurrence of long-period (or complex) polytypes could not be accounted for by phase considerations. This highlighted the need of a more detailed kinetic approach of the problem and, in particular, of the role growth mechanisms of basal faces could play in this crystallographic phenomenon.

1. Introduction. Studies of radiation damage in ceramics are of interest not only from a fundamental point of view but also because it is important to understand the behavior of ceramics in various practical radiation enyironments- fission and fusion reactors, nuclear waste storage media, ion-implantation devices, outer space, etc. A great deal of work has been done on the spectroscopy of point defects and small defect clusters in ceramics, but relatively little has been performed on defect agglomeration using transmission electron microscopy (TEM) in the same kind of detail that has been so successful in metals. This article will assess our present understanding of radiation damage in ceramics with illustrations using results obtained from the authors' work.

Structural Aspects

Osmoregulatory mechanisms in algae were investigated mainly from a physiological point of view (KAUSS 1977, HELLEBUST 1976). In Porphyra two osmotic agents, i. e. floridoside/isofloridoside (KAUSS 1968) and certain ions, such as K+ and Na+(EPPLEY et al. 1960) are considered for osmotic balance. Accumulations of ions (particularly Na+) in the cytoplasm during osmotic adaptation is improbable, because the activity of enzymes is generally inhibited by high ionic concentrations (FLOWERS et al. 1977).The cellular organization of Porphyra was studied with special emphasis on the development of the vacuolar system under different hyperosmotic conditions. Porphyra was cultivated at various strengths of the culture medium ASP 12 (PROVASOLI 1961) ranging from normal to 6 times concentrated (6x) culture medium. Por electron microscopy freeze fracturing was used (specimens fixed in 2% glutaraldehyde and incubated in 30% glycerol, preparation in a BALZERS BA 360 M apparatus), because chemical fixation gave poor results.

Hardened Cement Paste

It has been almost universally adopted that dissolution of solids proceeds with development of uniform, continuous frontiers of reaction.However this point of view is doubtful / 1 /. E.g. we have proved the active role of the block (grain) boundaries in the main phases of cement, these boundaries being the areas of hydrate phases' nucleation / 2 /. It has brought to the supposition that the dissolution frontier of cement particles in water is discrete. It seems also probable that the dissolution proceeds through the channels, which serve both for the liquid phase movement and for the drainage of the incongruant solution products. These channels can be appeared along the block boundaries.In order to demonsrate it, we have offered the method of phase-contrast impregnation of the hardened cement paste with the solution of methyl metacrylahe and benzoyl peroxide. The viscosity of this solution is equal to that of water.
