Authors: Epifanova I. V.
Published: January 2022

Relevanсe. The novelty of our research lies in the fact that for the first time the allelopathic interaction of eastern galega seeds with a wide range of oilseeds is being studied. The aim of this work is to study the allelopathic effect in the initial stages of plant ontogenesis. The objectives of the study were to identify cultures with a positive and negative impact on the growth and development of sprouts of eastern galega. The objects of research were eastern galega Magister, false saffron Alexandrite, saperda mustard Lux, spring rape Tavrion, hemp Nadezhda, spring cress Iskra, white mustard Lucia, abyssinian colewort Polet, ethiopian niger seed Medea, oil radish Fiolina, damascene fennelflower Yalita, hybrid sunflower P63 LE 10 (XF 3020), winter camelina Baron, spring camelina Velez, oilseed flax Istok. The experiments were carried out in two layouts in 2019–2020 on the basis of a separate division of the Federal research center for fiber crops in the Penza region.

Methods. The evaluation of allelopathic activity was carried out using a method that involves the germination of plant seeds, followed by the calculation of the percentage of germination. The number of seeds and seedlings at different stages of ontogenesis was determined along with measuring the length of the root, stem and leaf.

Results. At the initial stages of ontogenesis, a weak negative allelopathic effect on the eastern galega is exerted by the abyssinian colewort Polet — the number of fullfledged seedlings was -6,1% to the control. A positive effect on the germination and development of galega seedlings is exerted by damascene fennelflower Yalita (+8,3% to control), ethiopian niger seed Medea (+8,1 to control), oilseed flax Istok (+6,4% to control). In general, the length of the galega seedling was at the level of control with damascene fennelflower and ethiopian niger seed is 3,27 and 3,24 cm (-0,40 and 0,43 cm respectively). A significant decrease is observed in the variants with oilseed flax, spring camelina, winter camelina, spring rape, false saffron, sunflower, saperda mustard, white mustard, hemp, abyssinian colewort and spring cress — from 2,81 to 1,66 cm (-0,86–2,01 cm to control).

Published: January 2022

Relevance. The preservation, reproduction and rational use of agricultural soil fertility is the main condition for the stable development of the agro-industrial complex. Mechanical tillage systems, the use of mineral and microbiological fertilizers are one of the main links in adaptive landscape farming systems. In the conditions of a sharp decrease in the rates of fertilizer application, an increase in the imbalance of elements of mineral nutrition of plants observed in recent years in agroecosystems, the function of improving the regimes of chernozems, preserving their fertility is designed to perform resource-saving technologies of soil cultivation in combination with effective methods of using agrochemicals that combine environmental and economic feasibility.

Methods. The experiments were laid in 2017–2019 on chernozem heavy loamy soils typical for most farms in the Ulyanovsk region. The object of the study is spring wheat, the variety Ulyanovskaya 100. The subject of the study is the methods of tillage, doses of mineral fertilizers, the biological product "BisolbiFit". The following technological methods of using the biological product were studied: seed treatment before sowing, non-root treatment of vegetating plants and a combination of these methods. The experiment was carried out on three backgrounds: N0P0K0 (control); 2) N30P30K30; 3) N60P60K60.

Results. It was found that the best nitrification ability was possessed by variants with fine combback and comb-back with soil-deepening treatment, in which the weighted average content of nitrate nitrogen was 3.29–3.33 mg/100 g, which is 35–36%; 26–28%; 43–44% more than with fine, conventional non-dump and dump treatment respectively. Plowing improved the conditions of phosphorus and potassium nutrition of plants by 25–37% and 6–14% compared to other treatments. When N30P30K30 and N60 P60 K60 were applied to the soil, the content of nitrate nitrogen increased by 46 and 91%, phosphorus — by 0–14% and potassium — by 6 and 21% compared to the nonfertilized background. More effective in terms of the effect on the productivity of spring wheat were comb-shaped treatments, where the average yield was 2.89–2.94 t/ha, which exceeded the usual plowing by 0.19–0.24 t/ha. The greatest increase in yield was obtained when combining the methodsseed treatment + spraying of vegetative plants with the biological preparation "BisolbiFit". On an unfertilized background, the increase in grain yield was -0.71, on the background of N30P30K30 — 1.04, on the background of N60P60K60 — 1.56 t/ha.

Published: January 2022

The article presents the results of studying the productivity of the parameters of the introduced apple variety Majesti on the clonal rootstock M9 in the agro-ecological conditions of the southeastern foothill sub-province of Dagestan. The purpose of the research is to identify the biological potential of the variety, the adaptive potential for the construction of intensive-type orchards in the industrial horticulture zone. It is especially important to choose the optimal variety-rootstock combinations of apple trees, which should be distinguished by early maturity, annual productivity, high commercial quality of fruits and environmental sustainability. The southeastern foothill sub-province has great prospects for the development of industrial horticulture. Of the unfavorable environmental factors that negatively affect the vital activity of fruit crops, the most often noted are return colds in spring and early frosts in autumn, when fruit plants are still growing. In accordance with the research program of the Federal Agrarian Scientific Center of the Republic of Dagestan, it is envisaged to study the influence of different rootstocks (M9, SK-2, SK-7, MM106) on the productivity of the Majesti variety. Based on the research results, biometric indicators of the growth and productivity of trees in a young garden were determined, depending on the type of planting design. It was noted that at the age of three, the condition of trees on a 5-point scale is good. The height of the trees, depending on the rootstock, reached an average of 2.3 to 2.9 m. On dwarf rootstocks M9, the stem diameter of the Majesti variety was 4.2 cm, of the control variety Renet Simirenko — 3.5. The growth of annual shoots clearly reflects the growth activity of trees with different varieties of rootstock combinations. It has been established that the growth of dwarf rootstocks provides a weakening effect and allows growing lowgrowing trees with a compact crown, a strong stem, that are convenient for earning and harvesting. The largest number of fruit formations was noted in the introduced cultivar Majesti with a 3.0x1.5 planting pattern on a dwarf stock M9 (67 pieces) then in comparison on the control variety Renet Simirenko it was46 pieces. Productivity per tree was 7.1 kg, in the control variety Renet Simirenko — 5.3 kg. Calculated per hectare, productivity of the Majesti variety is 15.7 tons, Renet Simirenko — 11.7 tons.

Published: January 2022

Relevance. The problem associated with the continuing decline in the yield of the main crops and soil fertility in most of the arable lands leads to the need of developing comprehensive measures, including the optimal selection of crops and methods of tillage and planting in order to increase the collection of plant protein and preserve soil fertility.

Method. The work devoted to the study of the influence of tillage methods, mineral fertilizers and biological products on the productivity of forage crops and their mixed planting was carried out on the experimental fields of the Chechen Research Institute in 2019–2020 in the forest-steppe climatic zone. The experiment was multifactorial. Mineral fertilizers were used for crop rotation with a view to the planned yield. The biopreparation V417, created at the Institute of Agricultural Microbiology on the basis of the Bacillus subtilis strain, was used in the processing of seed material and crops during the period of intensive plant growth.

Results. As a result of the research, it was revealed that each of the studied methods of tillage should correspond to the cultivated crop and the technology used. The introduction of mineral fertilizers provided an increase in the productivity of forage plants in their pure and mixed planting by 11–44%. The treatment of crops with biopreparation V417 reflected in the best way: an increase in yield was from 24 to 52%. At the same time, the highest yield of the green mass of 42.6 t/ha was obtained in a three-component mixture (wheat, peas, oats) in the variants where disking and chiseling were carried out. Mixed planting is a serious reserve for increasing the quantity and quality of plant products. It's feed productivity in the collection of dry matter and feed units was not inferior to pure planting of cereals, and in terms of the provision of 1 feed unit with digestible protein exceeded it by 3–14%.

Relevance. Modern turkey crosses have a genetically determined high growth rate. These farm birds are very sensitive to even minor fluctuations in their diet, are susceptible to a deficiency of amino acids, protein, mineral elements and vitamins, which can contribute to a decrease in their productivity, the development of pathological processes and diseases. The use of modern technologies and scientific achievements has made it possible to prepare a new product — modified zeolite. This natural mineral is already free of impurities and microbes, with open pore windows, has a high ability to selectively exchange, and is obtained by various methods of activating zeolite in industrial conditions. At the same time, Ulyanovsk specialists have mastered the technology of enriching modified zeolite with useful substances.

Methods. The aim of the work was to study the effect on the body of turkeys and the level of their productivity of additives based on modified zeolite enriched with amino acids. The experiment was organized for 60 days on 250 turkeys of the breed Hybrid Cread-mayker aged 55–60 days in the conditions of the Ulyanovsk region. The control group received the main ration (MR), the experimental group was given once a day in addition to the MR in the morning feeding in a mixture with mixed feed 5% additives of modified zeolite enriched with amino acids.

Results. The inclusion of a supplement based on modified zeolite enriched with amino acids in the diet of turkeys does not have a negative effect on the hematological parameters of their blood, all indicators corresponded to the physiological norm. During the experiment in the 2nd group, the live weight of poultry was obtained larger by 8.70%, which amounted to 12,296 kg, respectively, more profit was obtained from the sale of turkey meat, total revenue was 133,210, and additional profit was 27,960 rubles, 2.41 rubles of profit was received for 1 ruble of costs. Тhe data indicate the normalization of mineral homeostasis in the body of turkeys and better absorption of nutrients in the feed diet.

Published: January 2022

Relevance. The article provides a justification for the use of sheep selection taking into account the intra-breed type of Prekos ewes in purebred breeding and crossing with producers of semi-fine wool breeds Romney-Marsh and Kuibyshevskaya to improve the biological usefulness of meat in offspring.

Methods: scientific and economic experiment in the use of different selection options, taking into account the productive type of sheep of the Precos breed.

Results. The article presents the results of a study on the influence of the selection of sheep on the composition of lambmeat, increasing the usefulness and quality of meat and, thus, the efficiency of its production. It was found that the content of water in the meat of crossbred animalswas lower compared to purebred Precos. There is a lower water content in the meat of rams obtained from sheep of the Precos meat-wool type, both in purebred and crossbred animals. In terms of the protein content in meat, there is an advantage in rams with purebred breeding and crossing compared to meat obtained from the wool-meat type of queens. In the hip bran of purebred animals and crossbreeds with the Kuibyshev breed, this superiority was 1.1% (Р > 0.95), and in the lumbar bran of Romney-Marsh crossbreeds, this difference was 1.6% (Р > 0.95). Mutton from the offspring of the sheep of meat-wool type is characterized by a significantly high content of the essential amino acids threanine, lysine, leucine, phenylanin and isoleucine in comparison with meat from the offspring of the wool-meat type of sheep. A significant superiority was also established in the content of interchangeable amino acids — oxyproline, serine, tyrosine, proline, glycine, aspartic and glutamic acid, cystine and analin.

The article is devoted to the urgent problem of developing a scientifically based organization and use of distant pastures in the south of Kazakhstan. It has been found that the composition and diversity of pasture grasses have significant effect on the forage value of the grass stand and ultimately affect the forage capacity of desert pastures. Grazing of farm animals should be carried out with an optimal load on pastures, that is, no more than 70% of the productivity of the pasture mass should be exploited. Due to the better preservation of various types of forage plants and pasture herbage in general with systematic use, the yield of pastures in the summer season was 6.15 c/ha, in other words it was higher by almost 1.0 c/ha of dry forage mass compared to unsystematic grazing (5.20 c/ha). All pasture plants exploited in early spring produced aftermath in 10–15 days and were well preserved from overexploitation and trampling.

Selada merupakan salah satu jenis tanaman sayuran yang mudah untuk dibudidaya dan dapat tumbuh subur dengan optimal pada suhu  25°C - 28°C dan kelembapan tanah 65% - 78%. Kendala keterbatasan lahan yang dimiliki menyebabkan sulitnya melakukan budidaya tanaman selada. Bilik tanaman adalah alternatif solusi untuk permasalahan tersebut. Bilik tanaman dibuat seperti ruangan bertingkat yang berisi susunan rak yang diisi tanah untuk menanam selada. Sistem ini menggunakan arduino uno, sensor suhu DHT22, sensor kelembapan tanah YL69, LCD, kipas DC, solenoid valve, dan raspberry pi. Hasil pengujian sistem, saat nilai suhu yang terdeteksi oleh sensor DHT22 lebih besar sama dengan 28°C maka sistem secara otomatis mengaktifkan kipas untuk mendinginkan bilik, dan saat suhu mencapai kurang atau sama dengan 25°C kipas secara otomatis mati. Untuk nilai kelembapan tanah, saat sensor YL69 kurang atau sama dengan 65% maka sistem secara otomatis menyiram tanaman dan saat kelembapan tanah lebih besar atau sama dengan 78% maka sistem berhenti menyiram tanaman. Semua kondisi sensor tersebut ditampilkan pada LCD I2C 16×2. Untuk hasil pengujian aplikasi whatsapp, saat pemilik mengirimkan perintah “cek tanaman”, maka sistem berhasil mengirimkan notifikasi keadaan bilik seperti suhu, kelembapan tanah, kipas dan  apakah sistem sedang menyiram tanaman atau tidak.

Published: January 2022

Pembangkit Listrik Tenaga Gas (PLTG) merupakan pembangkit dengan keunggulan waktu pengoperasian yang singkat dengan daya pembangkitan relatif besar. Dibalik kecepatan pembangkit tersebut untuk dioperasikan terdapat kelemahan yaitu tingkat efisiensi pembangkit yang tergolong rendah atau boros dalam penggunaan bahan bakar. Pada saat proses pengoperasian pembangkit di industri sering terjadi perubahan permintaan pasokan beban, untuk memenuhi permintaan tersebut pembangkit harus siap tertutama dalam ketersediaan bahan bakar. Permasalahan yang terjadi adalah PLTG tidak bisa dibebani daya maksimal karena sumber bahan bakarnya juga digunakan untuk bahan baku proses pokok industri. Penelitian ini bertujuan untuk mencari variasi temperatur inlet PLTG dengan besar nilai heat rate dan spesific fuel consumption (SFC) pada pola operasi PLTG yang paling optimal. Selanjutnya melakukan analisis keterkaitannya dengan efisiensi bahan bakar yang bisa dihemat di objek yang diteliti. Hasilnya dengan 39,7 % pembukaan katup gas dan temperatur masuk udara sebesar 30oC dan tekanan kompresi 7 bar menghasilkan nilai paling optimum dengan nilai SFC 0,627dan heat rate 8059.663 kcal/kWh. Pembukaan katup gas lain yaitu sebesar 42,9% pembukaan katup gas dan temperature masuk udara sebesar 30oC dan tekanan kompresi 7 bar menghasilkan nilai paling baik yaitu SFC 0.654 dan heat rate 8408.248 kcal/kWh.

Authors: Frendiana Viving , Rahmansyah Muhammad Teddy
Published: January 2022

Rangkaian matching dengan saluran transmisi λ/4, sering disebut juga dengan impedance transformator λ/4, adalah saluran transmisi atau pemandu gelombang (waveguide) dengan 1/4 panjang gelombang (φ) yg diterminasi dengan impedansi beban. Pada banyak aplikasi diinginkan kondisi tak adanya refleksi pada sambungan saluran transmisi. Oleh sebab itu untuk mengeliminasi refleksi akibat perbedaan impedansi beban dengan impedansi gelombang, dipakai teknik penyamaan/penyesuaian impedansi (impedance matching techniques). Penyepadanan impedansi dilakukan dengan tujuan untuk menyepadankan impedansi beban dengan impedansi karakteristik pada saluran transmisi agar saluran transmisi dapat matching, sehingga proses transmisi pada sejumlah daya tidak terjadi pantulan yang mengakibatkan seluruh daya yang ditransmisikan dapat diserap. Pada penelitian ini, dirancang penyelesaian rangkaian matching saluran transmisi λ/4 menggunakan pemrograman berbasis website. Hasil perhitungan simulasi menggunakan aplikasi website didapat nilai impedansi pada saluran transmisi dengan transformator λ/4 sesuai dengan perhitungan persamaan matematis. Proses matching pada perhitungan ini mensyaratkan impedansi beban yang riil.

Authors: Adi Sapria , Fatnanta Ferry , Satibi Syawal
Published: January 2022

The use of helical foundations to support structures on peat soil is still a new method. Research is needed to develop this foundation. There are 6 types of helical foundation tested on peat soil. To study the effect of helical plate diameter, plate diameters were varied with sizes 25 cm (M), 35 cm (L), and 45 cm (G). Plate positions (1, 2, 3 plates) are designed at 300 mm spacing. The axial compression bearing capacity test is carried out based on the constant rate of penetration procedure. At the beginning of loading, the load increases significantly. At a certain descent, the load begins to decrease slowly. The load-settlement curve shows that the larger the plate diameter, the greater the load it can withstand. The largest bearing capacity is produced by the GGG 30 foundation (3 plates dia.45 cm), which is 10.83 kN. LLL 30 helical foundation (3 plates dia.30 cm) provides a bearing capacity of 7.14 kN. These results clearly explain that the increase in plate diameter is directly proportional to the increase in the axial compression bearing capacity.

Akses terhadap sumber daya alam dianggap berhubungan dengan tingkat kemiskinan dan ketahanan pangan suatu komunitas masyarakat. Akses terhadap sumber daya alam khususnya yang bersifat milik bersama dan terbuka (common property and open access) seperti perairan, hutan dan perikanan, semakin semakin terancam karena pertumbuhan populasi yang tinggi meningkatkan permintaan terhadap sumber daya tersebut sehingga timbul kelangkaan. Metode penelitian kualitatif melalui literature Sehingga formula pengentasan kemiskinanpun tidak bisa digeneralisir pada semua wilayah atau semua sektor. Kemiskinan yang dialami oleh nelayan tidak bisa disamakan dengan ukuran kemiskinan buruh di perkotaan. Bahkan dalam suatu di kabupaten yang sama belum tentu bisa diratakan ukuranya pada desa-desa pesisir yang ada. Program pengentasan kemiskinan nelayan membutuhkan strategi khusus yang mampu menjawab realitas yang terjadi hari ini.Â Selain itu, peranan hukum juga menjadi sangat penting untuk mensejahterakan para nelayan.

Rozmowa Polaka z Włochem Łukasza Górnickiego. Przyczynek do historii edycji
Authors: Siess-Krzyszkowski Stanisław
Published: January 2022

Rozmowa Polaka z Włochem (A Discussion between a Pole and an Italian) is one of the most important political works by Łukasz Górnicki. Written at the end of the 16th century, it was repeatedly reprinted from the 17th century until today. It is also a widely known example of Polish literary plagiatrism: in 1616 Rozmowa was published by Jędrzej Suski as his own work. For a long time Suski edition was considered to be identical with the anonymous version of Rozmowa published sine anno and sine loco, but in 2008 Anna Sitkowa described the actual plagiatrized version with the dedication letter signed by Suski himself. Moreover, typographical analyses of the anonymous version of Rozmowa indicate that it was in fact printed in 1630s, and thus it is not a first, but a third edition of the work. Determining the correct order of editions has significant consequences regarding textual history and criticism.
Legal regulations concerning the preservation and protection of library collections in Poland after World War II
Authors: Nowicki Ryszard
Published: January 2022

The article presents the problem of the practical application of legal regulations related to the preservation and protection of written cultural heritage in Poland after World War II, within the borders of 1945. The first legislative initiatives were undertaken in 1944. The introduction of normative provisions was initiated on a patch of Polish territory free from the German occupant. The war events, changes in the shape of the country’s borders and the political system made it necessary to develop national documents in order to protect library collections, regardless of their origin. It was not an easy task to implement due to numerous difficulties and a complicated post-war reality. Based on few legislative provisions, over ten million volumes, mostly of post-German provenance, were saved until 1949. Valuable written materials were used to partially compensate for the World War II losses, rebuild libraries and Polish librarianship.

The efficient use of some innovative technologies in adhesives with advanced operational characteristics development aimed at anti-corrosion properties increase of transport means has been substantiated in the paper under discussion. The above-mentioned technologies involving the use of some interaction-active ingredients forming the cross-linkable coatings composition, including some polymers, have provided their cohesion properties essential improvement. Epoxy diane oligomer ED-16 has been chosen as the main component for the matrix in the composite formation. The aliphatic resin DЕG-1 (GOST 10136-77) as a plasticizer has been added to the epoxy oligomer. The compound has been formed of the following concentration: epoxy resin ED-16: plasticizer DЕG -1 – 100: 40. The hardener of cold hardening polyethelenepolyamine PEPA (ТУ 6-05-241-202-78) has been used at the epoxy resin-based developed materials polymerization. Phthalic acid anhydride has been used as a modifier to improve the properties of epoxy composite materials. The modifier was added to the matrix in the following ratio: from 0,10 to 2,00 pts.wt. per 100 pts.wt. of epoxy oligomer ЕD-20. The molecular formula of the modifier is as follows: C8H4O3. Molar mass is 148,1 g/mol. Density is ρ = 1,52 г/см³. To form a composite material or a protective coating with some improved adhesive properties and inconsiderable residual stresses the phthalic acid anhydride as a modifier was found to be added to the epoxy matrix with the content q = 1,25 pts.wt. per 100 pts.wt. of the epoxy matrix (oligomer ЕD-20 + plasticizer DЕG -1). In this case, the adhesive strength of the coating is being increased from sа = 28,3 MPа to sа = 46,4 MPа, and residual stresses – from sз = 1,9 MPа to sз = 2,1 MPа. First of all, the improved properties of the modified materials were caused by the interaction of active carbonyl (С=О) groups of the modifier with nitrogen-containing (NH-) groups of the hardener. It has provided the increase of the composite cross-linking degree resulted in their both adhesive and cohesion properties improvement. Moreover, it was found that the modifier use in the compound with the content q = 1,0…1,5 00 pts.wt. per 100 00 pts.wt. of the matrix has provided the increase of the river water influenced coatings resistance from ρ = 12,1 Оm·cm2 до ρ = 21,2…22,4 Оm·cm2. Though, some further increase of the additive content in the coating has caused the deterioration of anti-corrosion characteristics of the materials. Thus, the conducted study has contributed to the determination of the most efficient content ratio of phthalic acid anhydride as a modifier to for the coatings of functional use.

Published: January 2022

The fluid flows and power consumption in a vessel stirred by anchor impellers are investigated in this paper. The case of rheologically complex fluids modeled by the Bingham-Papanastasiou model is considered. New modifications in the design of the classical anchor impeller are introduced. A horizontal blade is added to the standard geometry of the anchor, and the effect of its inclination angle (α) is explored. Four geometrical configurations are realized, namely: α = 0°, 20°, 40°, and 60°. The effects of the number of added horizontal blades, Reynolds number, and Bingham number are also examined. The obtained findings reveal that the most efficient impeller design is that with (case 4) arm blades inclined by 60°.This case allowed the most expansive cavern size with enhanced shearing in the whole vessel volume. The effect of adding second horizontal arm blades (with 60°) gave better hydrodynamic performance only with a slight increase in power consumption. A significant impact of Bingham number (Bn) was observed, where Bn = 5 allowed obtaining the lowest power input and most expansive well-stirred region.
