Published: March 2021

The problem of studying behavior of various structures under the influence of intense impulsive (shock) loads arising during operation of many modern facilities, machines and devices remains relevant for many years. Shock loading in laboratory conditions is generated due to interaction between the test object and the braking device (barrier). In this case, braking device or barrier could be a one-piece or a prefabricated structure. If the braking device (barrier) dimensions commensurate with the test object, the braking device natural oscillation frequencies excited during interaction between the test object and the braking device (barrier) could be found in the range of the test object natural oscillation frequencies. Frequency determination within the signal spectrum registered on the test object and caused by oscillations of the braking device (barrier) or test equipment, would assist in better assessing the test object shock loading and its compliance with real operating conditions
Assessment of Machinery Production Organization Efficiency Based on a Unified Quality Criterion
Authors: Zavozina O.Yu.
Published: March 2021

The main indicator of the machinery production organization efficiency is a stable demand for the company's products in a long-term period. Demand is affected by two main characteristics: product quality and market price. The ratio of these two characteristics should be optimal for each type of product. The paper considers an approach to assessing the position of products on the market based on the analysis of the price-quality ratio. The purpose of the study is to develop a methodology for determining the efficiency of the machinery production organization by product characteristics, assessed in the system of a unified quality criterion. In our research, we introduce a method for calculating a unified quality criterion for widespread engineering products, and propose a new form of recording the quality criterion in the form of a unified criterion taking into account the vector of weight coefficients of the significance of products by branches of industry, which is the scientific novelty of the work. We applied an original method of assigning points to calculate this vector, and we found that for most manufacturers, the dependence of a unified quality criterion on the price of products is presented in the form of an S-shaped curve. Furthermore, we analyzed the market of bearings and identified analogues to study the quality level. The calculation of the criterion for quality indicators among analogs was performed. On the basis of the obtained calculations of a unified criterion, the relationship between the price and the quality of the product was compiled in the form of the Verhulst equation. The data are shown as a graph of the logistic function. By the example of a Russian manufacturer of bearings, specific recommendations are given to improve the price-quality ratio for certain parameters. The efficiency of organizing production of a specific machinery enterprise is assessed

Authors: Rtischeva A.S.
Published: March 2021

For an advanced trisonic wind tunnel of a straight-flow type with a test section size of 1.2 × 1.2, intended for ground tests of rocket-space and aviation aircraft models, we implemented a gas-dynamic design of the circuit and did numerical simulation of the flow for the main supersonic regimes (M = 2, M = 4). The gas-dynamic design of the wind tunnel circuit was carried out on the basis of techniques developed at TsAGI and operating experience of existing facilities. The study considers both traditional configurations of the duct with the bending of the walls of all elements, i.e., nozzle, test section and diffuser in the XY plane, and alternative design developments with the bending of the diffuser walls in the XZ plane. When carrying out numerical studies in all areas of the wind tunnel, the ANSYS Fluent software package was used to solve the Navier --- Stokes equations for viscous and heat-conducting air using the turbulence model, i.e., Spalart --- Allmaras, SST. The paper investigates the effect of the wall opening angle, compensating the increasing thickness of boundary-layer longwise displacement, on the flow characteristics; shows the possibilities of obtaining a sufficiently uniform flow with the Mach number accuracy ΔM = ± 0.005 in the area of the model, and analyzes the influence of geometric parameters and boundary conditions on the efficiency of the supersonic diffuser

Authors: Aleksandrov An.A. , Zakharov M.N. , Kuts M.S.
Published: March 2021

The usage of renewable energy sources and energy storage devices allows an enterprise to reduce its electricity supply costs. Significant savings can be achieved only in the case of a well-organized system of managing energy flows of the enterprise and electricity consumption. The puprpose of the study was to analyze the existing storage devices and renewable energy sources, and on the basis of the analysis, introduce an approach to organizing energy supply of the enterprise based on the usage of storage devices and renewable energy sources. The approach introduced implies the electricity purchase schedule curve optimization to minimize the total costs. The purchase schedule curve optimization for the case of energy storage usage is an ill-posed problem. Within the framework of solving the problem, the form of the curve was formalized to a piecewise constant function, which made it possible to solve it by applying multi-criteria optimization based on a modified method of directed random search. We analyzed a model case, for which an optimal purchase schedule curve was obtained using storage devices and solar panels, and the achievable economic effect from their use was graphed. The maximum value of operational costs, which makes the usage of energy storage and renewable energy source efficient, was found

Background: The use of magnetic resonance (MR) tractography in neurosurgery is becoming an increasingly common practice for noninvasive imaging of white matter pathways. The most common method of tract reconstruction is the deterministic algorithm of diffusion tensor magnetic resonance imaging (MRI). However, this method of reconstructing pathways has a  number of significant limitations. The most important of them are the lack of the possibility of visualizing the intersecting fibers, the complexity of building tracts in the area of perifocal edema and in the immediate vicinity of the tumor borders. The method of MR tractography, based on obtaining a  diffusion image with a  high angular resolution (High Angular Resolution Diffusion Imaging, HARDI), using the constrained spherical deconvolution (CSD) algorithm for post-processing of data, makes it possible to avoid these disadvantages. Relatively recently, a new algorithm, Single-Shell 3-Tissue CSD (SS3TCSD), has been proposed for processing HARDI data, which has the potential to improve the reconstructing of pathways in the area of perifocal edema or edema-infiltration.Aim: To evaluate the potential of the new SS3TCSD algorithm compared to ST-CSD (Single-Tissue CSD) in the imaging of the optic radiation and visual tracts in patients with gliomas.Materials and methods: Diffusion and routine brain MRI was performed in 10 patients with newly diagnosed cerebral gliomas, followed by reconstruction of the optic radiation and visual tracts. We compared new algorithms for postprocessing MR tractography (ST-CSD and SS3TCSD) in imaging of the optic tract and visual radiation in patients with brain gliomas affecting various parts of the visual system.Results: The SS3T-CSD method showed a  lower mean percentage of false positive tracts compared to the ST-CSD method: 19.75% for the SS3T-CSD method and 80.32% for the ST-CSD method in cases of proximity of the tumor to the tracts, 5.27% for the SS3T-CSD method and 25.27% for the STCSD method in cases of reconstructing tracts in healthy white matter.Conclusion: The SS3T-CSD method has a number of advantages over ST-CSD and allows for successful imaging of the optic pathways that have a complex structure and repeatedly change direction along their course.

Published: March 2021

World’s population is growing exponentially and agriculture has to fulfil their food requirements. An important strategy for increasing productivity and labour utilization per unit area of available land is to intensify land use. Intercropping is advanced agro technique of cultivating two or more crops in the same space at the same time. It increases in productivity per unit of land via better utilisation of resources, minimises the risks, reduces weed competition and stabilizes the yield. Millets are ancient nutri-cereals which play an important role in food and nutritional security of the country. They are commonly grown as sole crop world-wide. Pulse production can be increased by growing pulses on favourable lands that are occupied by cereals and cash crops by way of intercropping. The combination of cereal and legume in intercropping is mostly preferred by the farmers in subsistence farming targeting livelihood security. In this study, the works carried out by various researches in millet and pulse based intercropping are discussed. This review would be useful to the researchers who are involved in this field.

The Relationship between Seed Vigor and Germination Performance under Various Chloride Salts in Pea
Authors: Kaya G.
Published: March 2021

Background: Salinity is a severe abiotic stress resulting in inhibiting germination, seedling growth of crop plants. Germination performance under salinity depends on seed vigor and genotypic factors. This study aimed to determine if there was a relationship between germination and seedling growth of eight pea cultivars subjected to three chloride salts and the results of seed vigor tests. Methods: Pea cultivars Ambassador, Bolero, Electra, Esprit, Puccet, Rainer, Utrillo and Winner were germinated in the medium with three chloride salts of NaCl, MgCl2 and CaCl2 with the electrical conductivity (EC) of 20 dS m-1. Also germination percentage, mean germination time, controlled deterioration (CD) and electrical conductivity (EC) test were evaluated. Result: The seed vigor of pea cultivars was significantly different and salinity led to a significant decline in parameters of the cultivars. The most hazardous salt was MgCl2, while the least harmful was NaCl. Germination percentage was negatively related with MGT and EC values and EC test was strongly correlated with CD test. Utrillo and Winner were the most sensitive cultivars to MgCl2 and CaCl2. Although germination percentage of Rainer under non-saline was the lowest with 76%, it showed better performance under salinity than Utrillo and Winner. Germination percentage and CD gave a negative significant correlation with NaCl, but MGT and EC associated positively with NaCl. It was concluded that seed vigor should be considered as an indicator for the germination performance of pea seeds under NaCl, whereas genotypic factors play a key factor for tolerance to salinity during germination and early development stages.

Published: March 2021

Currently, the information about Javan langurs female reproductive cycle in both cycle length and hormonal patterns is still widely unknown. Meanwhile, this information can be used as a guide in determining the fertile period of Javan langurs to conduct mating with higher pregnancy rate. The purpose of this study was to determine the reproductive cycle of adult female Javan langurs based on estrogen and luteinizing hormone (LH) levels. The experimental animals was originated from Coban Talun forest in Batu, which was undergoing a rehabilitation program. Feces samples of two female Javan langurs were taken for 40 days. Examination of estrogen and LH hormone levels in the feces was carried out by the enzyme-linked immunosorbent assay (ELISA) method and then analyzed descriptively. The results showed that fluctuations in the graphs of the hormones estrogen and LH appeared on days 8 to 16 and days 30 to 40 which showed the existence of two reproductive cycles. Whereas younger langur showed a pattern of hormonal fluctuations that are less regular, making identification of the reproductive cycle difficult. Based from the results, we concluded that the reproductive cycle of female Javan langur was estimated about 24 days with a hormonal pattern consisting of the follicular phase, the ovulation period and the luteal phase.
Intensive Parenting in High-Resource Multi-Child Families

Published: March 2021

Current views about parenting involves the use of expert knowledge in the field of education and upbringing. The available variety of information and opportunities in this area requires parents to engage actively not only at the stage of choosing an educational trajectory for their children, but also in the process of their implementation. Large families with a fairly high income and education set a high educational level for their children, embarking on the path of modern intensive parenting, they use their own resources to achieve results. However, it is obvious that large families, taking into account the number of children and the accumulated experience of parents, have some features in this area. Thus, the work shows that parenting experience in such families allows a more rational approach to the choice of activities and their number, while carefully selecting educational institutions for their children, often depending on the abilities and needs of each child, creating individual educational trajectories. It is also noted that an important component of the educational process is the formation of an intra-family educational environment, which in large families has the ability to self-regulate and recreate. The chosen strategy of intensive parenting, which involves a significant amount of investment in the educational and upbringing process of children, requires focusing resources on children, including through the underutilization of the human capital of parents in the labor market (usually mothers). However, this strategy is considered as the most rational by parents.

One of the commonly used chemotherapy drugs is cyclophosphamide. However, the use of cyclophosphamide can provide various toxic effects. The most common toxic effect of cyclophosphamide is bone marrow suppression with anemia as one of its markers. The antioxidant content of cainito leaf potentially increase the production of blood cells, especially erythrocytes. The aims of this study is determining the effectiveness of the cainito leaf ethanol extract against cyclophosphamide induced mouse erythrocyte count in vivo. A sample of 20 male wistar rats was divided into five groups; normal group, negative control group, and three groups of ethanol extract of cainito leaf with dose 100 mg/kgBW, 200 mg/kgBW, and 400 mg/kgBW were administered for one week followed by intraperitoneal cyclophosphamide with dose 50 mg/kgBW as much as one time. One Way Anova Test result showed a significance of 0.015 (p<0.05). However, the LSD test results showed no significant different results between the negative control group and the treatment group. The conclusion was that there was no difference in the amount of erythrocytes in mice given only cyclophosphamide with previous rats given cainito extract.

Biofilm is a mechanism of bacterial defense against antimicrobials that can cause resistance. Staphylococcus aureus is a biofilm-producing bacteria and the most often cause of skin and soft tissue infections. Therefore, efforts are needed to prevent the formation of Staphylococcus aureus biofilms. Basil leaves are herbal plants that contain eugenol and tannin compounds, which are thought to inhibit the formation of biofilms. This research is a laboratory experimental study that aims to prove the effect of basil leaves ethanol extract (Ocimum sanctum) on the establishment of Staphylococcus aureus biofilms with in vitro method and determine the minimum inhibitory biofilm concentration needed. In this study, the tube method with 7 different concentrations was used. The results of biofilm ring formation obtained and measured quantitatively using Mean Gray Value in Adobe Photoshop CS6. From the study’s results, is found that the increase in extract concentration is directly proportional to the thinning of the biofilm ring on the tube with a minimum inhibitory concentration of biofilm at a concentration of 30%. The Pearson correlation test showed a very strong and significant correlation (r = 0.898, p = 0,000), and the Oneway ANOVA comparison test known a significant difference among the mean of each group (p = 0,000). From these results it can be known that the ethanol extract Ocimum sanctum can inhibit the formation of Staphylococcus aureus biofilms in vitro.

Published: March 2021

Chronic kidney disease (CKD) is a structural and function disorder of renal for > 3 months with implications for individual health. CKD has become a health problem throughout the world and its implementation provides a considerable economic burden on the health system. The decreasing value of GFR (glomerular filtration rate) in CKD can cause uric acid retention so that serum uric acid levels increase (hyperuricemia). Hyperuricemia can occur due to an increase in urinary metabolism (overproduction), a decrease in uric acid expenditure (underexcretion), or a combination of both. The group of antihyperuricemic drugs that have good effectiveness and long-term safety is xanthine oxidase inhibitors. The commonly used xanthine oxidase inhibitor drug is allopurinol. The purpose of this study was to determine whether there was an effect of allopurinol on kidney function in CKD patients. The results of this study are expected to provide input in the treatment of hyperuricemia in CKD patients and reduce the progression of CKD. This study used a retrospective observational analytic design with a cross-sectional approach. The study population was CKD patients from January 2018 to January 2019 at Bina Sehat Hospital Jember. The sampling technique uses purposive sampling. This study uses secondary data obtained from medical records of CKD patients at Bina Sehat Hospital Jember. Secondary data obtained in the form of identity data and the results of laboratory tests of patients. The medical record data that has been obtained is distributed and analyzed using a paired T-test to compare the mean or mean differences of the two groups in pairs. The bivariate test results for blood urea nitrogen and serum creatinine levels in CKD patients were obtained p <0.001. Based on these results there is a significant relationship between blood urea nitrogen and serum creatinine levels before and after consuming allopurinol. The conclusion was that allopurinol was shown to be able to provide an effect on the kidney function of CKD patients based on blood urea nitrogen and serum creatinine levels.

Methods: The authors have analyzed and applied best practice of the leading tram companies in Europe (Vienna, Prague, Riga, etc.), analyzed the most progressive designs of the rolling stock and their undercarriage, and compared foreign and domestic experience of service facilities operation. Results: The experience of many European companies has proved the feasibility of using cars with swivel bogies, which have a beneﬁcial effect on the track and make it possible to pass curves of small radii. The use of wagons made of multi-link structures allowed designing a completely low-ﬂoor cabin. It is advisable to place a gearbox and an electric drive on the outside of the low-ﬂoor car undercarriage, or to use a gearless drive and low-speed electric motors. Practical importance: The introduction of low-ﬂoor cars in cities improves the accessibility of this type of transport for passengers, primarily for passengers with disabilities, and signiﬁcantly reduces the time of their boarding (disembarking). The advantage of cars with swivel bogies is shown. The increased complexity of the undercarriage design allows designers to create an extremely low ﬂoor cabin, but this consequently leads to an increase in the cost of rolling stock, an increase in repair costs, stricter requirements for the support services and a demand for highly qualiﬁed technical personnel. It is recommended to purchase domestic low-ﬂoor rolling stock as the most adapted to operation in Russian cities.
