Authors: Lebedeva N. V. , Fateev N. N. , Nikulina A. L. , Zimina O. L. , Garbul E. A. 
Published: December 2018

The total content of mercury was studied in marine water, sediments and benthic organisms in Billefjord, Isfjord and Gronfjord (Western Spitsbergen) in 2017. The samples were collected between 21 and 24 of July 2017 on-board RV “Dalnie Zelentsy” of Murmansk Marine Biological Institute. Total mercury content was measured at chemical-analytical laboratory of the Russian Scientific Center on Spitsbergen in Barentsburg.Total mercury concentration in the water did not exceed 10 ng/l in all fjords. In the surface sediments the highest concentrations of total mercury were found in Isfjord (median 55 ng/g d.w.) while the Billefjord sediments were characterised by the lowest concentrations (median 10.4 ng/g d.w.). This fact might reflect the differences in water circulation and therefore sediment accumulation peculiarities.Total mercury data were obtained for benthic organisms of various feeding modes. Generally mercury levels were comparatively low (median 12.2 ng/g w.w.), however the highest concentrations were measured in the benthic fauna of Isfjord, specifically in polychaetes Maldania sarsi (max. 49.2 ng/g w.w.). Mercury accumulation in benthic organisms predominantly depended on their trophic level in the ecosystem and location in the fjord: benthic detritus feeders accumulate more mercury (median 25.0 ng/gw.w.).
Similarity and difference of bioenergy characteristics of polychaetes in bottom communities in the shallow gulfs of the Arctic and Antarctic
Authors: Gagaev S. Yu. 
Published: December 2018

Comparison of energetic ﬂ ow through bottom communities (on the example of polychaete populations) in the shallow bights the Chaun Bay (East Arctic) and the Fjord Nella (East Antarctic) located in high latitudes of opposite hemispheres of the planet is carried out for the ﬁ rst time. Polychaete worms abundantly and diversely represented in the bottom biocenosis and playing an important role in their life are one of the most suitable for this kind of analysis of the group. The material is collected and processed by common methods. It turned out that the average values of biomass and assimilation are comparable, although their indices are somewhat higher in Chaun Bay than in Nella Fjord, so the mean values of the current energy are 56 ± 25 and 40 ± 13 kcal / m2 per year, respectively. In this case, such similarity is mainly due to the duration of the light time due to the location of the bays on similar geographical latitudes. In both cases, it was noted that at lower depths, lower values of the energy ﬂ ux are inherent in different sections of the gulf, due to freshening and abrasion of the ice, and higher — at great depths, where the conditions are more stable. It has been established that in the Chaun Bay the share of the biomass of suspension feeders is higher on hard bottom in the macrophyte belt, and on the muds occupying the largest areas of the bottom, deposit feeders predominate. In the Nella Fjord, on the contrary, large areas of the bottom are represented by hard substratum and are occupied, respectively, prevalence of suspension feeders, whereas non-large areas with a slight glossiness are used for life in small forms of infauna and which, according to the type of food, refer to deposit feeders. One of the distinguishing features of the assimilation in the considered bays is the tendency of its growth with depth in the Chaun Bay and its relative constancy in the Nella Fjord; the other is the achievement of relatively high values of the energy ﬂ ux in some parts of the shallow Arctic compared with Antarctica. The differences are apparently explained by the complexity and variability of the water regime in the Chaun Bay and by the greater silting of the bottom, compared to the relatively constant natural conditions of the Nella Fjord, which together determine the features of the functioning of populations of polychaetes, as well as other groups of inhabitants.The bioenergetic characteristics of bottom communities in the shallow bays of the Arctic and Antarctic have both differences and similarities, and, on the whole, depend on the physico-chemical originality of the areas.
Numerical implementation of the initial-boundary value problem for nonlinear the onedimensional equations of poroelasticity for the water-ice system
Authors: Korobov P. V. 
Published: December 2018

Summary This article is devoted to the problem of propagation of elastic transverse oscillations in a two-phase medium consisting of water and ice (ice impregnated with water). If we consider ice as a kind of porous homogeneous medium with constant partial density, then it becomes possible to apply the problems of the theory of filtration to the water-ice medium. In this paper, we consider one of the possible formulations of the direct problem modeling the propagation of a signal in this medium is considered. The initial-boundary value problem for a one-dimensional nonlinear system of poroelasticity equations is solved by numerical method on the basis of an explicit-difference scheme. A series of numerical calculations for a trial model of the media is presented.The aim of the paper is to describe the approach to the study of water-ice media using the equations of filtration theory. The object of the study is the propagation of wave oscillations in such media. Such fluctuations can have different nature (seismic, acoustic, etc.). For example, it is of interest to use this approach to model the propagation of sea waves in the ice of the initial stage of ice formation.

Authors: Sah Deb Narayan , Sharma Bishnu Dev 
Published: December 2018

Background and Objectives: Plantar fasciitis is a common pathological condition that affects the hind foot. Management of plantar fasciitis employs use of various non-surgical and surgical treatment methods. The aim of this study was to evaluate the efficacy of steroid injection in the treatment of plantar fasciitis in adults.
Materials and Methods: From January 2016 to June 2017, fifty patients aged >18 years with plantar fasciitis symptomatic for three months or more were injected with a single dose of methylprednisolone acetate with 2% lignocaine. Assessment was done using visual analogue scale (VAS) and foot function index (pain sub-scale). Patients were followed-up for a period of 6 months.
Results:There was significant reduction in VAS score and improvement in foot function index at 1 and 3 month follow-up (p<0.001) as compared to pre-injection score but this VAS reduction or improvement in foot function index was not significant at 6 month follow-up (p=0.057 and 0.729 respectively). There were no major adverse effects of the steroid injection.
Conclusion: A single dose of corticosteroid injection provides only a short term benefit in plantar fasciitis.

Background and Objectives: Bacteria can cause allergic asthma and seasonal allergies, diseases which are increasingly prevalent in developing nations. Allergic asthma is currently affecting millions of people in Nepal. Therefore, the objective of this study was designed to measure the bacterial load in outdoor air.
Materials and Methods: Airborne outdoor bacteria were assessed during the spring season using conventional methods to investigate the enumeration of airborne microorganisms. This was determined by sampling air using the ‘settle plate technique’. The air samples were collected during the spring season (February-March) from 10 different areas of Janakpur. Counts of airborne bacteria were measured as CFUs collected by gravity onto Nutrients Agar plates. Samples were taken periodically over a period of 2 months of February and March 2017.
Results: A total of 7,404 bacterial colonies were counted on 30 Petri plates that were exposed for 1 hour. The maximum number of colonies of bacteria was 412. Similarly, the least number of bacterial colonies was 32. Higher numbers of CFUs were found in the petri plates which were exposed for 1 hour in comparison to the petri plates which were exposed for 30 minutes. According to the measurement, 36.6% of total CFUs of bacteria were collected during morning hours, 28.4% during day time and 35% during evening hours. Also, the highest numbers of colonies of bacteria were found in the petri plates that were exposed in ward number 7 and the least number of bacterial colonies were obtained in ward number 9.
Conclusion: The bacteriological quality of air in janakpur was very poor. Very high microbial load was found in the outdoor air in Janakpur. The microbial count was found higher in morning than the noon and evening.

Published: December 2018

The paper highlights the research conducted in order to assess the effect of different doses of thyme extract on the productive properties and livability of broiler chickens. The experiment was conducted at a broiler poultry farm with a closed production cycle; the experiment assumed the control group and 5 experimental groups where each group contained 37 broilers at floor housing. The broilers of the 1st experimental group were fed with the extract of medicinal plant thyme dosed 2 mg/kg; broilers of the 2nd group received thyme extract dosed 4 mg/kg; 3rd group of broilers – 6 mg/kg, 4th group -8 mg/kg, and the dosage of the thyme extract was 10 mg/kg for broilers in the 5th experimental group. The authors controlled the live weight of broilers in each group by means of individual weighing every 7 days. Using this data the researchers calculated average daily body weight gain, absolute and relative gain; feed consumption was daily calculated. Feed consumption became the basis for calculating feed costs per a kilo of live weight gain. The authors recorded the number of daily fallen chickens. The data on poultry loss was the basis for calculating poultry livability. In order to assess production efficiency, the European productivity index was calculated. The research results indicate the efficiency of thyme extract application in different doses when feeding the broiler. Application of thyme extract in feeding meat poultry allowed to increase productive properties of broilers from experimental groups from 2.3 to 4.7%, reduce feed costs per a kilo by 1.1-8.1%, increase poultry livability on 2.7-8.1% and increase the European productivity index in the experimental groups on 0.2 21.3%.

We studied the subtoxic effect of small doses of sodium fluoride on the activity of microsomal hepatocytes on 30 Wistar rats' populations in subacute experiment. The intensity of lipid peroxidation (LPO) in liver of rats which were administered sodium fluoride orally for a long time at doses of 1/10 and 1/100 LD50, was evaluated by the content of its molecular products - diene conjugates (DC), and MDA-reagents Schiff bases. We found that oral administration of sodium fluoride to rats at doses of 1/10 and 1/100 LD50 promotes a statistically significant increase (r≤0,002) relative to the control group of animals in DC content during the entire period of observation. At a dose 1/10 LD50 we observed the most significant increase in this indicator on the 10th day of the experiment - at 265%, and at a dose 1/100 LD50 – on the 20th day an average of 234%. In rats’ liver by the action of subtoxical dose of sodium fluoride at a dose of 1/10 LD50, starting from the 20th day, we detected a gradual increase (r≤0.001) of TBA-reagents relative to control - for 27, 41, 78, 133%. Secondary end products and lipid peroxidation, which are defined under the long-term of sodium fluoride, somehow contribute to the disruption of the microstructure of hepatocytes membranes, their permeability, reduce their division, regeneration and inhibition of mitochondrial respiratory chain enzymes and microsomal monooxygenase system.

Published: December 2018

The problem and the goal.The urgency of the problem of mathematical description of dynamic adaptive testing is due to the need to diagnose the cognitive abilities of students for independent learning activities. The goal of the article is to develop a Markov mathematical model of the interaction of an active agent (AA) with the Liquidator state machine, canceling incorrect actions, which will allow mathematically describe dynamic adaptive testing with an estimated feedback.The research methodologyconsists of an analysis of the results of research by domestic and foreign scientists on dynamic adaptive testing in education, namely: an activity approach that implements AA developmental problem-solving training; organizational and technological approach to managing the actions of AA in terms of evaluative feedback; Markow’s theory of cement and reinforcement learning.Results.On the basis of the theory of Markov processes, a Markov mathematical model of the interaction of an active agent with a finite state machine, canceling incorrect actions, was developed. This allows you to develop a model for diagnosing the procedural characteristics of students ‘learning activities, including: building axiograms of total reward for students’ actions; probability distribution of states of the solution of the problem of identifying elements of the structure of a complex object calculate the number of AA actions required to achieve the target state depending on the number of elements that need to be identified; construct a scatter plot of active agents by target states in space (R, k), where R is the total reward AA, k is the number of actions performed.Conclusion.Markov’s mathematical model of the interaction of an active agent with a finite state machine, canceling wrong actions allows you to design dynamic adaptive tests and diagnostics of changes in the procedural characteristics of educational activities. The results and conclusions allow to formulate the principles of dynamic adaptive testing based on the estimated feedback.

Developing and Sustaining a Multilevel Competitive Learning Organization – A Behavioral and Cognitive Approach
Authors: العنزي سعد , اسماعيل مصطفى 
Published: December 2018

To maintain a sustained competitive position in the contemporary environment of knowledge economy, organizations as an open social systems must have an ability to learn and know how to adapt to rapid changes in a proper fashion so that organizational objectives will be achieved efficiently and effectively. A multilevel approach is adopted proposing that organizational learning suffers from the lack of interest about the strategic competitive performance of the organization. This remains implicit almost in all models of organizational learning and there is little focus on how learning organizations achieve sustainable competitive advantage . A dynamic model that captures the strategic nature of organizational learning is the competitive learning organization . This type of organizations approach sustainable competitive learning by reshaping their strategy, structure, and culture for growth to be attained continuously at the individual and groups(micro), integrative network (meso), organization and interorganizational (macro) levels .Learning by itself is not enough to attain a sustainable competitive advantage. Rather, the most important thing is that how best to focus the learning on the most prominent forces resulted from changes and fluctuations in the competitive environment .
