Authors: Mansyur
Published: December 2019

Indonesia is one of the countries that have a high earthquake intensity. Therefore, in building structure planning, there needs to be a more in-depth study of the analysis and planning of earthquake-resistant structures. The study aimed to find out the results of the building analysis reviewed in 4 Indonesian cities based on SNI 03-1726-2012 with computer programs. This research is computer-based research, with Microsoft Excel application for wall density index analysis on 1-story and 2-story buildings, and SAP2000 v.20 application on 4-story buildings for static analysis of equivalent lateral forces. In reviewing the building with analysis of wall density index, it was very influential on the magnitude of the spectral acceleration value of the earthquake. The greater of the spectral acceleration value of the earthquake in the city being reviewed, the smaller the value of the seismic capacity control of the building, which affects the level of building safety. In a building review with an equivalent static lateral force analysis, base shear and displacement values were very influential on the magnitude of the earthquake intensity if used as a comparison with other cities. In reviewing buildings with dynamic analysis of spectrum response range, base shear and displacement values were not very influential on the magnitude of the earthquake intensity if used as a comparison with other cities due to the greater burden than the earthquake load.

Published: December 2019

Stomata are presumable to be a potential taxonomic differentiating character. This study was aimed to describe the leaf stomata characteristics of banana from different genomic groups, to analyze its clustering pattern, and to confirm the potential character of leaf stomata as a taxonomic marker. Plant materials used in this study were twelve banana leaves; representing 6 genomic groups (AAw, AAcv, AAA, AAB, ABB, and BBw). Stomata observation was carried out by replica method on both adaxial and abaxial of leaf near to petiole. Results showed that number of stomata in all bananas were higher on abaxial than adaxial. The diploid bananas have rounded shape of stomata while the triploid bananas have elliptical shape. Bananas with B genome tend to have regular stomata arrangement. Ploidy level in bananas is inversely correlated to the number of stomata, but positively correlated to stomata length and size. The diploid bananas were having high number of stomata but smaller stomata length and size, than the triploids. The genome size is influenced to the stomata size. Bananas with A genome tend to have larger stomata size than B genome bananas. Clustering analysis based on stomata profiles resulted two main groups following its ploidy level and genomic groups. Thus, stomata profiles can be used as a complementary character to classify among different genomic groups of banana.

Published: December 2019

Trees and saplings of two mangrove species, Rhizophora stylosa Griff. and Rhizophora mucronata Lam. were observed in herbivory level (leaf damage area and percentage of herbivory) and leaf nutrients (total nitrogen, phosphorus, potassium, water content and deterrent tannin). We observed mangrove habitat located around Institut Teknologi Sepuluh November (ITS) Campus in Surabaya, East Java dominated by Rhizophora vegetation. Herbivorous insects showed an individual abundance of 15.15% of the total insects found in mangroves around the studied areas. Seedlings tended to be significantly higher in relative leaf damage and preferred by the herbivores than trees. One way ANOVA showed a non-significant difference in leaf area damage between two species (F=0.63, p-0.43; F=2.29; p-0.13). The concentration of leaf nutrients was significantly different between two species than habitus. Total nitrogen and water content in R. mucronata were significantly higher than in R. stylosa (F=5.10, p-0.03; F=142.13, p-<0.0001), whereas phosphorous and potassium (K) was significantly higher in R. stylosa than in R. mucronata (F=15.25, p-0.0002; F=75.916; p-<0.0001). Descriptively, R. stylosa leaves tended to be higher in deterrent tannins than R. mucronata, especially in seedling habitus. Leaf age, represented by plant habitus, is less to be related to high leaf palatability and insect herbivore nutrition than mangrove species.

Authors: Andrimida Anthon , Hermawan R
Published: December 2019

The heterobranch sea slugs are one of the most under-studied marine lifeforms found around the Sempu Strait Area. Currently, the records of their occurrences around this area are only known from the underwater macrophotography enthusiast’s collection and have not been published on a scientific article. We conducted underwater surveys spanning from October 2017 to June 2019 at eleven dive sites of Sempu Strait and yielded 45 different species of heterobranch sea slugs, including 35 species of Nudibranchia, 6 Aplysiida (Anaspidea), 2 Cephalaspidea, and 2 Sacoglossa. The analysis of the sea slugs occurrence on Sempu Strait reveals that the areas around the Western Sempu Strait, including Rumah Apung, Kondang Buntung, Tiga Warna, and Stumbut have the most diverse sea slugs species, even though the majority of the species have a low sighting frequency. The analysis also revealed that roughly a third of the sea slugs encountered on the Sempu Strait areas are found on the coral rubble substrate. This study revealed that Sempu Strait has slightly lower sea slug species diversity than another nearby studied site. The records provided here hopefully could help to encourage macro-photography recreational dive activities to further develop the ecotourism sector around this area.

Published: December 2019

When creating new resistant varieties of rice of an intensive type, an important aspect of the breeding process is the study of the diversity of cultural genetic resources. In the Krasnodar Territory, in Russia and in the world as a whole, the most harmful and common rice disease is pyricularosis (Pyricularia oryzae Br.et Cav.). The aim of this work was to study the genetic diversity accumulated in the collection of the rice institute (ARRRI, Krasnodar city) for the resistance to the causative agent of pyriculariosis to create a new source material with genes for a wide spectrum of resistance. In the course of studies, the results of phenotypic (1337 samples), immunological (775 samples) and molecular screening (115 samples) of the gene pool of Oryza sativa L. were obtained for the resistance to the pathogen of pyriculariosis. The rate of development of the disease (RDD,%) over the years of testing the general plasma varied within 5.6-85.0%. The proportion of varieties medium resistant to the fungus M. Grisea was significantly higher in almost all countries except Italy and Brazil, where the number of resistant forms was at the level of medium resistant. In the general plasma of Bulgaria, Uruguay, Greece, India and African countries, stable forms were generally absent. The world variety of rice genotypes showing resistance to the local pathogen population has been shown. Screening of the rice gene pool for the presence of the Pi-9 and Pi-k genes made it possible not only to identify carrier donors, but also to establish their frequency of occurrence in the global general plasma. Against a provocative background, the identification of effective resistance genes was carried out using monogenic differentiator lines of Pyricularia oryzae races, 15 resistance genes were isolated.

Published: December 2019

Restoration of case parts of machines significantly reduces the cost of their repairing. The present paper proposes a method for restoring case parts using the repair size method. Depending on wear degree, the fitment holes are bored to three repair sizes. The prepared hole is inserted with a new bearing, the outer ring of which is covered with a polymeric coating of the appropriate thickness ensuring the fixity of the joint. As a result of theoretical studies, the model was obtained for the formation of a uniform polymer coating on the outer surface of a rotating cylindrical part. The facility and technological equipment were developed for applying a polymer coating of F-40C elastomer solution onto the outer surface of the rotating bearing. The facility includes screwing lathe 1K62, centering drift pin, bath and magnetic holder MV-V. The holder is designed for mounting a bath filled with polymer solution and its plunging movement when rolling bearings are immersed in polymer solution. The drift pin serves for centering and assembling bearings. The assembled drift pin is inserted into the chuck of the machine rotating the pin when applying polymer coating. The screwing lathe 1K62 is equipped with an INNOVERT frequency converter of H3400A05D5K type, which allows adjusting infinitely the spindle speed from 0 min-1. The paper presents the results of experimental studies on the F-40C elastomer shrinkage, the parameters of the mode of immersing parts into its solution, the dependence of the geometric parameters of the formed polymer coating on the components of application and adhesion modes for polymer coatings based on F-40C elastomer solutions of different viscosity. The acceptable thickness of the polymer coating of elastomer F-40C on the bearing 209, ensuring the non-failure operation of the restored seating with a cyclic radial load of 20 kN is 0.1 mm.

Bread is a product of daily consumption. That is why development of functional bakery products is important. New recipes and technologies using enriching additives allow expanding the range and improve physiology of bakery products. The goal of this research was to identify the impact of bakery mix ingredients on the quality and biological value of bread. The objectives of the research: to identify technological qualities of flour and flakes, study the possibility of using flakes for bakery mixtures in bread production; assess the impact of flakes on the quality and biological value of wheat bread. The objects of the studies: mixture of 5 corns (oat, wheat, rye, barley, millet flakes). To identify the impact of flakes on the quality of wheat bread, two bread samples were made – control sample without flakes and testing sample with mixture of 5 corns. The proportion of flakes was 10% of the total mass of flour and flakes. This study used a method of complex evaluation with complex indicators of quality combinations which were supposed to consider the importance of each criterion. Every single indicator of quality was characterized by two parameters: relative ratio and weightiness. The used complex evaluation method allowed making a conclusion about the practicability of using flake products in bread production. Studies show that in case of adding mixed flakes in the amount of 10% from the total mass of flour when making wheat bread, the quality can be improved and the biological value of bread can be increase.

The results of the study carried out in the northern forest-steppe foothills of the SouthEast of Western Siberia in 2014-2017 in order to assess the impact of seed treatment and winter rye crops for vegetation by bioorganic nano-fertilizer NAGRO on the grain yield and quality and to identify the most effective option are presented. Vlada and Tetra short varieties were studied, treated according to six experimental options. Two types of biofertilizers were used: bioenergetics NAGRO – for daily treatment of seeds and crops and NAGRO universal – for treatment of crops during vegetation. Control – seeding without the use of bio-fertilizer. Presowing seed treatment carried out by NAGRO bioenergetics with the norm 1 l/t, the crops by NAGRO universal with the norm 1 l/ha and by the bioenergetics – 0.2 l/ha. Working solution volume is 250 l/ha. The increase in yield on the variants of the experiment with respect to the control of Vlad varieties by 7 – 20%, Tetra short varieties by 7 – 15%. More efficient yields were the crops with the treatment options in the variety of Vlada – three (seed treatment with bioenergetics, 1st treatment on vegetation – bioenergetics in the phase of tillering in the spring, the 2nd processing – universal in the earing phase); the varieties of Tetra short - two (seed treatment with bioenergetics, 1st treatment on vegetation – universal + bioenergetics in the phase of tillering in the spring, the 2nd treatment – universal in the earing phase). The greatest number of falls was observed in Tetra short variant two, for Vlada - in variant three.

The article is devoted to the consideration of the peculiarities of the development of agrarian-industrial regions in the conditions of the implementation of the policy of rational import substitution of food products under the sanctions pressure of Western countries. The object for the study is socio-economic relations arising in the process of implementing the strategy of rational import substitution in the agrarian-industrial region. The main statistical indicators of the activities of the agro-industrial complex (AIC) in Russia are analyzed. Also, the main problems faced by the regional cluster of the AIC are identified. The factors constraining the development of agro-industrial regions and the intensification of points of economic growth in the regions are systematized. A special attention is paid to the theoretical and methodological foundations of evaluation of the points of economic growth of the regions focused on the development of the agricultural sector. As a result of the study, it can be concluded that sustainable balanced development requires a policy of proactive import substitution, focused on emerging new markets, aimed at improving the economic security of the Russian economy in the global market segments.

The study was aimed at studying the dynamics of connections between wheat plant elements under external mechanical forces. Biological and physico-mechanical features of separating grain from ear were determined. The effect of physical and mechanical impact, changes in parameters of moisture and temperature of the environment and the effect of varietal features on quality indexes of winter wheat grain were studied (mass fraction of protein and gluten). Problems of seed micro damages were studied using two varieties, different in the strength of connections between grain and ear. It was discovered that the largest amount of micro damages of the studied “Luchezar” and “Admiral” varieties was registered when grain with its maximum moisture content was threshed and the amount of micro damages was 54% and 55% (moisture content 34.3%). The highest mass fraction of protein was registered in the phase of milk-wax ripeness of grain of “Luchezar” variety (14.67%) and “Admiral” variety (14.60). Gluten content changed depending on grain moisture, in case of “Luchezar” variety from 23.9% to 19.7%, and “Admiral” variety from 24.6% to 22.5% (grain moisture content 19.5-9.7%). On the overripe stage (5-10 days), gluten content declined from 24.6% (the beginning of harvesting) to 22.5% (15 days of the overripe stage). The research goal was to study physico-mechanical features in the separation of grain from ear due to changes in its biological characteristics.

The paper studied the effect of microbial polysaccharides on the leukogram of laboratory animals and studied the dynamics of peripheral blood parameters with an assessment of immunobiological reactivity based on established patterns of physiological status. The results of numerous studies of the state of natural resistance of farm animals indicate that protective forces are a dynamic indicator, and is determined both by the genetic characteristics of the body and the impact of various environmental factors. This circumstance allows directionally influencing the formation and manifestation of the body’s defenses. Thus, the study of the immunological reactivity of the organism of farm animals becomes relevant for understanding the pathogenesis of diseases, for rational pathogenetic therapy. The problem of increasing the nonspecific resistance of productive animals has not lost its relevance in the current difficult economic situation in Russia. This fact is dangerous by the manifestation of enzootic outbreaks of infectious diseases and a gradual decrease in the breeding value of animals.

In the “Q-factor” laboratory of the Don State Technical University, seeding planters are created with the original design of sowing devices, using modern materials and technologies. The design of a row seeding planter is considered, which allows coordinating the speed of the seed and the speed of the unit for a better sowing process. A new classification feature in the design of the row precise seeding planter is designated - the height of the sowing device from the bottom of the furrow. The characteristic features of the constructions of serial seeding planters on the basis of the aforecited feature were identified and analyzed. The rationale for the need to improve the technological process of sowing seeds of row crops by serial seeding planters is given. The problem is indicated, which is the lack of automation in controlling the precision sowing process during the operation of the seeding planters. A functional diagram and design of a sowing device with a seed tube is proposed, in which the ability to control the flight speed of seeds directly during sowing is implemented. A setup for testing the sowing device is presented with the aim of increasing the accuracy of determining the parameters of the operating modes of the sowing device of precise seeding planters in laboratory conditions. The results of laboratory experiments are obtained, which makes it possible to judge the possibility of controlling the speed of seeds directly during sowing process.

This paper describes the results of parasitological monitoring of pond farms in the Krasnodar region. It was found that in the warm-water aquaculture of various systems, 25 species of fish parasites were invaded, and the fauna of parasites was determined. The obtained results are the basis for the analysis of the system of medical and preventive measures and actualize the development of new means and methods of treatment and prevention of diseases. It is established that the complex anthelmintic drug, according to the generally accepted classification of chemical compounds in accordance with the degree of danger, can be attributed to moderately hazardous compounds, and by cumulative properties - to the group of substances with weakly expressed cumulation. With repeated administration of the new drug to fish, there were no significant changes in the clinical status, some hematological and biochemical parameters, which is one of the necessary conditions for the possibility of using anthelmintic in clinical studies. As a result of a single therapeutic feeding with the use of a combined anthelmintic at a dose of 50 mg/kg, the 100% extensive and intensive efficiency of the deworming of carps invaded by Philometroides lusiana and Bothriocephalus acheilognathi was obtained.
