The study ascertained the level of social inclusion
of migrant fisher folks in agricultural extension service benefits in Delta
State, Nigeria. One hundred and forty-one (141) available fisher folks were
used out of the 158 identified along purposively selected fishing communities
in the study area. The intention was to use all the identified fisher folks,
but in various communities covered, few of them excused themselves because of
the appointments they had in various respective places. As a result 17 of them
were not interviewed. Data were collected using interview schedule and
questionnaire. Data were analysed using frequency counts, percentages and
means. Inferential statistics was used in testing the hypotheses. The study
found that the migrant fisher folks had a mean age of 41.50 years, most
(81.56%) were married, majority (59.57%) had primary education and the highest
formally educated of them had secondary education and an average household size
of 5 persons and average fishing experience of 16 years. However, most (74.47%)
of them did not subscribe to membership of fisheries related groups. Their
level of social inclusion in agricultural extension services was poor (social
inclusion index = 0.41). Their average annual fish catch was 2000 kg and this
was adjudged to be poor. Their level of social inclusion positively influenced
their level of fish catch (r= 0.65) and their socioeconomic attributes also
influenced their level of inclusion in agricultural extension service delivery.
Most of the migrant fisher folks were socially excluded from agricultural
extension service delivery. Social inclusion of migrant fisher folks should be
encouraged, and migrant fisher folks need to be encouraged to subscribe to
membership of fisheries related groups.

New achievements should be directed towards reducing iron deficiency in
the plant and ultimately increasing the nutritional quality of agricultural
products. An experiment was conducted to find the effects of various ratios of nano scales zero valent
iron to iron chelate (NI/ Iron chelate) (0:100, 25:75, 50:50, 75:25 and 100:0)
at a concentration of 1.5 mg L-1 in different pH levels (5.5, 7.0
and 8.5) of nutrients solutions on yield, growth and photosynthesis pigments of broccoli
plants in floating
system. The experiment was designed as a factorial combination and treatments
were arranged in a completely randomized design with three replicates. The results indicated that
the growth of broccoli plants in terms of biomass and photosynthesis pigments were significantly
affected by both different levels of NI/ Iron chelate and nutrient solution pH. The highest amount of head fresh weight was
observed in
concomitant application of 50:50
ratio and pH=7.0 nutrient solution, which
was 32.53% more than the control treatment. The results of this
experiment showed that the use of different ratios of NI/Iron chelate up to
50:50 levels improved the growth and yield of broccoli plants. As first report, the
results of this experiment suggested that nano scale zero valent iron powders
could increase the growth and yield of broccoli plants.

Published: October 2019

The paper is devoted to the problem of producing hard, wear-resistant materials by SHS-casting using centrifugal forces. We have developed a device for centrifugal SHS casting and initial compositions of the reactive iron-base charge. A technology for producing coatings, materials and final products with a non-uniform distribution of strengthening particles over the specimen volume has been developed and tested in industrial conditions. The microstructure and phase composition of the synthesized material with a non-uniform distribution of reinforcing particles is studied. The synthesized material implements the Charpy principle: dispersed hard carbide particles are distributed in a relatively soft matrix, which ensures high wear resistance. By means of SHS casting, billets were obtained for producing a measurement instrument, namely a plug-type gauge, which successfully passed industrial tests at OJSC “VIZAS”. The tests shown that the hardness of all synthesized samples was in the range from 63 to 68 HRC and the number of measurements per 1 micron of wear on a diameter of15 mm was 2500 to 2700. Hence, the developed method made it possible to significantly increase the service life of the measuring tool: by a factor of 1.5 to 2.
Coordination of forces of mechanical and electric subsystems of power plant with free piston engine and electric generator of reciprocating type
Authors: Menzhinski A. B.
Published: October 2019

Autonomous power supply system of modern mobile special-purpose equipment requires the development of electromechanical energy converters with high energy and minimum weight- and size indicators. In industrialized countries, the system “free piston engine – reciprocating electric generator of transverse type” is considered as a promising power plant. The main feature of this kind of power plant is the lack of crank mechanism in the engine design. This allows: increasing the efficiency of the engine up to 50–60 % and overall power by 2.5–3 times while reducing the specific gravity and metal consumption compared to traditional engines; reducing the specific fuel consumption of the engine up to 30 %; increasing the resource to overhaul by 30–50 thousand hours; implementing a modular structure. The main drawbacks of this kind of power plant are high probability of failure when passing the ignition of the working mixture and instability of work with significant load fluctuations. The noted drawbacks are due to the inconsistency of the forces of the electrical and mechanical subsystems of the power plant throughout the operating cycle. The solution for the problem of matching the forces of the electrical and mechanical subsystems of the power plant in the extreme positions of the piston group of the free piston engine is of particular complexity. In this regard, a method for solving the problem of matching the forces of the mechanical and electrical subsystems of the power plant with a free-piston engine throughout the operating cycle was developed, characterized by the use of an electromechanical reciprocating energy converter with transverse- and longitudinal nonlinear changes in the magnetic flux in the electrical subsystem. Coordination of the forces of mechanical and electrical subsystems of the power plant on the entire operating cycle makes it possible to fulfill the conditions of continuous electromechanical energy conversion at all work cycle and to reduce the specific gravity of the electrical subsystems of the plant while improving efficiency.

Published: October 2019

The study of reliability indicators was carried out on the example of a cluster supercomputer configuration of “SKIF-GEO” (further cluster) worked out within the framework of the scientific and technical program “SKIF-Nedra” (2015–2018, Program of the Union State of Russia and Belarus). The cluster is a stationary supercomputer configuration designed to solve resource-intensive applications in data processing centers (DPC). Computing platforms and other cluster modules are located in the same 19′′ rack height of 42U. Theoretical peak performance of cluster – 100 Tflop/s. The basic architectural principles implemented in the cluster, the composition and structural-functional scheme of the cluster are given. A methodological support for calculating the reliability of the cluster, based on previous studies by the authors, is proposed. Taking into account these studies, the structural scheme of reliability (SSR) of the cluster, consisting of two parts – the cluster core and the combination of computing facilities (nodes) (CCF), is substantiated. The component parts (CP) include components of the cluster, the failure of which leads to a decrease in performance to zero. CCF includes CP of cluster, the failures of which lead to a decrease in cluster performance. The choice of the main indicators of the reliability of the cluster core and CCF is grounded and formulas for calculating these indicators are given. The analysis of the consequences of failures of cluster components is made. Taking into account the analysis, the SSR of the cluster core is determined, which allows to derive a formula for calculating the cluster core reliability indicators. A mathematical model of reliability (state graph) of an CCF cluster is proposed, which allows one to derive formulas for calculating the mean time to failure and the mean time for a failure of the CCF of cluster. An assessment of the reliability of CP cluster, for which there is no reliable information on their reliability, is determined based on the SSR of these CP. An assessment of the reliability of the cluster as a whole, based on the calculation of reliability indicators based on reference data on the reliability of components and components, as well as on data from the operation of supercomputers of family “SKIF” has been carried out. Taking into account this estimation and the calculated ratios obtained, the cluster reliability indicators for two options were calculated (in the presence and absence of a reserve of computing nodes). High values of cluster reliability indicators were achieved due to the architectural and structural solutions adopted in the process of its development, aimed at increasing its survivability.

The aim of the current work is to perform a probabilistic dose assessment to quantify the relative importance of the source data uncertainties contribution towards the uncertainty estimates of collective and maximum individual doses of personnel during decommissioning of a storage facility. A probabilistic approach to the analysis of dose loads, including the analysis of sensitivity and uncertainty with respect to the input parameters of the used calculation models of dose assessment, allows to determine the most sensitive parameters, inaccuracies in the task of which lead to significant uncertainties in the estimates of dose loads on personnel and, therefore, require more accurate determination of conservative boundary values in deterministic analysis and safety justification. The calculations were performed by applying the code RESRAD-BUILD 3.50, developed by the Argonne National Laboratory of the US Department of Energy. The obtained results allow us to rank the parameters of the computational model according to the degree of their influence on the uncertainty of the final estimates of the dose loads on personnel, to develop recommendations for optimizing dose loads when performing radiation-hazardous work during nuclear facilities decommissioning.

The existence of freshwater crayfish in Indonesia is not well known among the community, even some people think that this type of lobster can only be obtained from catches. Freshwater lobster cultivators are always faced with the classic problem of low survival, especially during seed stages. The role of the water bottom substrate for freshwater crayfish is to support stabilizing water quality (temperature, pH, dissolved oxygen and ammonia levels). If the substrate condition of the habitat is not suitable, it can inhibit growth and even death. The purpose of this study is; to find out the effect of different basic substrates can increase the survival and growth of freshwater lobsters. The research method used a Completely Randomized Design (CRD) with 4 treatments 3 replications and 1 control. Each container is stocked with 2-inch lobster seeds with a density of 10 heads / container. The substrate application for each treatment is: A = Control, B = Land, C = Sand Malang, and D = Gravel. Based on the results of the research that has been done, it can be concluded that the administration of different substrates only shows significant differences in the survival variable, with the highest number of 96,67% in treatment C (Malang sand) and the lowest with 66,00% in treatment A (Control). While the variables of absolute weight, absolute length, and daily growth rate did not show significant differences in all treatments.

As one of fish commodity, Catfish (Pangasius pangasius) has a very important economic value for the community. The time needed for catfish cultivation tends to be long and the price of feed is high so that it triggers the less optimal production of catfish. One way to maximize good production and with minimized time is by adding multivitamin probiotics to the feed. This research aims to analyze the optimal dose of probiotics to the growth and survival rate of catfish . Method used is Complete Randomized Design Design (CRDD) using 4 treatments of probiotic doses and 3 replicates. The treatments are A Control (0.00 ml/kg), B (10 ml/kg), C (15 ml/kg), and D (20 ml/kg). Absolute weight, absolute length, and survival of catfish are the main variables observed. The data were analyzed by using the analysis of variance and continued with the LSD test (the Least Significant Difference), Ü = 0.05. The optimal dose of probiotics based on the absolute length and absolute weight of catfish is 10 ml/kg and it produces an absolute weight of 5.27 gram and absolute length of 5.76 cm. The optimal daily specific growth rate is at the probiotics dose of 10 ml/kg which is 2.302.55%/day. The highest survival rate for catfish is 100% at probiotic doses of 0.000 ml/kg, 10 ml/kg and 15 ml/kg. The range of water quality is in the temperature of 27.5 – 28,90C, pH 6.79 - 7.88, DO 6.4 - 7.9 ppm, and ammonia 0 ppm.

Komponen penyimpan energi semakin dibutuhkan seiring dengan berkembangnya peralatan berenergi listrik. Namun, komponen penyimpan energi yang terdapat di pasaran memiliki banyak kelemahan sehingga mengurangi efisiensi penggunaan alat listrik. Superkapasitor memiliki keunggulan dalam beberapa hal dibandingkan kapasitor dan baterai kimia. Selain mempunyai kualitas yang lebih bagus, superkapasitor pula dapat dibuat dari material yang relatif murah dan mudah didapat. Materialnya yaitu MnO2 dan karbon. Dengan menggunakan metode elektrolisis yang cukup sederhana, MnO2 disintesis dalam ukuran nanopartikel agar kapasitas penyimpanan semakin besar. Nanopartikel MnO2 dikompositkan bersama karbon sehingga menghasilkan superkapasitor yang memiliki kapasitas dan konduktivitas yang tinggi dengan memvariasikan tegangan yang dijalankan sebesar 2 V ; 2,5 V ; 3 V ; dan 3,5 V ketika sintesis MnO2. Dari penelitian ini, kami mendapatkan hasil berupa kapasitas MnO2 tertinggi yaitu sintesis pada tegangan 2 V dengan nilai kapasitansisebesar 48 F/g. Nilai tersebut seribu kali lebih besar dari nilai kapasitansi kapasitor komersial. Sehingga dapat disimpulkan bahwa kondisi yang tepat untuk sintesis MnO2 yaitu pada tegangan 2 V.Kata Kunci : elektroda, nanokomposit, superkapasitor
