Published: February 2022

The efficiency of mineral fertilizers depends upon various factors, one of which is fertilization method. In heterogeneous condition of fields of nutrient content, the benefits of variable rate fertilization will increase, cause as much fertilizer will be applied to each section of the field as is necessary specifically on this section to obtain the planned yield. Experimental results have revealed the following features: variable rate fertilizer of nitrogen to reduce the variability of the nitrate nitrogen content in the tillering phase of spring wheat to 36% relative to the content before sowing, variable rate fertilizer of phosphorus and potassium to reduce variability of labile phosphorus and potassium in soil to the phase of wheat harvesting by 11 and 21%. The fertilization of one rate is less effective. This method leads to a decrease in the variability of nitrate nitrogen to 48%, labile phosphorus by 10%, by variability of labile potassium increases by 17% in the same time. Yield of spring wheat was 4.36-4.46 t / ha with a protein content of 14.03-14.57%, wet gluten 33.0-35.0%, glassiness 87-88%, weight of 1000 grain 36.1-36.3 g were applied with variable rate fertilizers in off-line mode.

The cytogenetic characteristics of rabbits are presented using a micronucleus test, which makes it possible to improve existing breeds and types, to seek opportunities for the accelerated creation of new forms of animals. In the FGBNU NIIPZK, during the formation of a breeding group of rabbits, data on the reproductive capacity of males were obtained and correlated with the results of the micronucleus test. Determination of the stability of the genome of rabbits of the created breed using the micronucleus test showed that the frequency of occurrence of erythrocytes with micronuclei varied in males in the range of 0.1 - 1.3 ‰ or on average was 0.55 ± 0.07 ‰. The research results showed that in the outbred group of males, the range of fluctuations in cytogenetic characteristics was from 0.1 ‰ to 1.17 ‰, inbred, respectively, from 0.1 ‰ to 1.3 ‰. At the same time, in males with different reproductive ability in groups, differences in the frequency of occurrence of erythrocytes with micronuclei were revealed. Based on the assessment of the reproductive ability of males of the main herd of the breed being created, participating in outbred mating, 8 males were selected with 100% fertilizing ability of the fertile females and average indicators: fertility - 8.8 ± 0.7 (head), the frequency of occurrence of erythrocytes with micronuclei 0.56 ± 0.15; participating in inbred mating, 8 males were selected with 100% fertilizing ability of covered females and average indicators: fertility: 8.7 ± 0.4 (head), the frequency of occurrence of erythrocytes with micronuclei 0.77 ± 0.15 ‰.

Authors: Shkrabak Roman Vladimirovich
Published: February 2022

It is informed about the importance of the structures of the agro-industrial corps in world civilization and in the country in terms of food supply for the population. Attention is drawn to the need for a variety of food products, which is ensured by the versatility of agricultural enterprises and a variety of types of work. The mechanization of agricultural production is based on a variety of agricultural machinery and equipment used in order to increase productivity, production efficiency and facilitate labor. It is noted that in the fleet of agricultural equipment used, the determining share of mobile machines with internal combustion engines (cars, tractors, combines, bulldozers, excavators, scrapers and other machines) on a wheeled or crawler track is drawn. According to the regulatory and legal framework, all types of work activities should not lead to injury and illness of workers. At the same time, many of them, for one reason or another, are accompanied by severe and fatal injuries. One of the reasons is the ability to start their engines when the gear is engaged in the transmission. In order to eliminate such situations, an innovative solution has been proposed - a device for blocking the possibility of starting the engines of mobile machines if the gear shift lever is not set to the neutral position before starting. This prevents the possibility of injury to operators and persons servicing the unit.

Published: February 2022

In the dry-steppe zone of the Volga region, characterized by an extremely arid climate, the stability of crop production depends directly on the level of development of reclamation. In this regard, the priority is to carry out a set of effective environmental measures that take into account data from the monitoring of irrigated land using modern technologies and methods that prevent the development of negative natural processes and ensure the conservation of land and water resources. The article describes the dynamics of the state of irrigation potential in the Volga region, the justification of rational areas of irrigated land in accordance with the requirements of the scientific system of agriculture, as well as the state of the main elements of reclamation funds owned by agricultural producers. It has been established that in recent years there has been not only a general decline in the area of watering land, but also a sharp deterioration in the condition of reclamation funds, especially on the internal irrigation network. The possibilities of reconstruction and rehabilitation of the reclamation complex, and related issues of financing and price policy are considered. The necessity of wide use of mechanisms of state subsidization of reconstruction and rehabilitation of irrigation sites was noted.

The genesis of the herd of the Sychevskaya breed in the conditions of the leading breeding farms of the Smolensk region was evaluated using one-factor dispersion and entropy-information analysis. The study involved 2362 cows. The study period was divided into six time phases according to the date of birth of the animals. An increase in the level of productivity and reproductive properties of cows during the first lactation was established. By the sixth time phase, the milk production increased by 747 kg per standard lactation. There was also an increase in the content and amount of milk fat. According to the time stages of the study, the level of the Holstein blood fraction changed in cows. The applied method of "infusion" of blood of red-mottled Holsteins had an unstable effect on milk productivity and reproductive properties. The open-days of cows with the level of Holstein "blood" above 41% has increased. The method of one-factor analysis of variance established a reliable probability of the influence of the time stage of birth of cows on the amount of milk, milk fat, age of first insemination, open-days. Entropy-information analysis revealed the consolidation of the "milk yield" trait and the organization of the control system of the fat-milk content of animals.

In recent years, there has been a growing interest in using genetic techniques to create more disease-resistant livestock herds. In such studies, the mannose-binding lectin 1 (MBL1) gene is one of the promising genes because of its important role in the immune system. The study was aimed at studying the polymorphism (p. 2569 T> C) of the MBL1-Hae III gene by PCR-RFLP in the Holstein cattle population of the Republic of Tatarstan. In the course of DNA diagnostics 1059 cows of Integrated Agricultural Production Centre “Stud farm named after Lenin" of the Atninsky district were identified alleles C (0.637) and T (0.363), and genotypes CC (42.3%), TC (42.8%) and TT (14.9%). The variability between the observed and expected distribution of genotypes was 5.98. Chi-square testing found that the genetic balance in the study population was not disturbed. Analysis of the genetic structure of various populations and breeds of cattle demonstrates that, depending on the breed, the frequency of occurrence of one or another genotype changes. The results obtained in the study provide important information that can be used in future breeding and breeding programs using markers for groups of Holstein cattle resistant to diseases.

The article presents studies aimed at a comparative assessment of the meat productivity and quality of meat of young sheep of the Stavropol breed of different genotypes (CASTNN and CASTMM) identified by PCR – PDRF and studies of chemical and histological parameters. According to the results of the control slaughter, the superiority of the CASTNN genotype over the CASTMM genotype analogue in terms of the pre-slaughter mass by 9.1%, the mass of the paired carcass and its yield by 12.3 and 3.4% was revealed. Indicators of the morphological composition of CASTNN genotype carcasses meet the requirements of GOST I category. Morphometric analysis indicates a smaller number of muscle, connective-woven fibers, but a larger diameter of muscle fibers in the meat of the CASTNN genotype than in the CASTMM meat, which provided it with a higher score of "marbling": 32.41 vs. 27.17. To identify particularly valuable animals and their wide application in the breeding process, it is advisable to use the PCR analysis method in conjunction with morpho-histological studies.

Fisheries productivity plays an important role in national development. The potential of fisheries in Indonesia is quite large so that many coastal communities depend on their lives from fishing activities. East Java province has a fishery area that is quite potential with the availability of considerable human resources, one of them is Lamongan. This research was conducted in Fish Auction Site (Tempat Pelelangan Ikan, TPI) Kranji, Lamongan. The purpose of this study is to find out the productivity value of purse seine fisheries in TPI Kranji based on the size of the ship and the fishing trip. This research was conducted by survey method to know the condition of purse seine fishery in the field directly. Purse seine fishing vessels located in TPI Kranji in 2020 as many as 32 ships that have gross tonnage (GT) of 9 to 24 GT. The dominant catches are Longtail Tuna (Thunnus tonggol), Mackerel Tuna (Euthynnus affinis), Fringescale Sardinella (Sardinella fimbriata), Short Mackerel (Rastrelliger brachysoma) and Goldstripe Sardinella (Sardinella gibbosa). There are two seasons in the fishing process at TPI Kranji, the regular season (Fringescale Sardinella) and the peak season (Tuna). The highest value of productivity per trip was obtained 1.59 tons / trip / year which occurred in 2019 with 223 of fishing trips and the amount of catch production of 356.71 tons. The highest value of productivity per GT occurred in 2020, obtained 2.09 tons / GT / year, which currently has 32 purse seine vessels. The productivity per GT from year to year is increasing because the amount of production is also increasing every year.
Plasmacyte Heterogeneity of Lame Ducklings
Authors: Cotter Paul F.
Published: February 2022

The aim is to describe the array of plasmacytes (PC), cells known as the source of antibody, occurring in the bone marrow (BM) of lame ducklings. The method is by a light microscopic examination of touch preparation slides made from femur samples and stained with Wright-Giemsa. Samples were obtained on site at commercial farms where slide preparations were made; reducing the possibility that observations are technical artifacts. The results: indicate that PC occur in a multitude of sizes, shapes, nuclear/cytoplasmic (N/C) ratios, ploidy, and nuclear and cytoplasmic conditions. Normal PC are illustrated first, followed by atypical forms. Some PC are presented in the context of neighboring BM cells of the granulocyte, erythrocyte, and reticulum cell (histiocyte) series. More than 100 Mott-type PC were measured in a single sample from a 13-day lame duck; and several distinct forms were identified. Size, as measured by their longest axis, varied from 6.1 to 28 μm and it appears to be normally distributed. Moreover, N/C ratios were distributed across a three-fold range (0.3 – 0.9) indicating Mott phenotypes can occur at multiple developmental stages. Motts differed in Russell Body (RB) size, and nuclear condition. A novel Mott type, “orb” form, with partially lysed nuclei is also described. PC were often found in association with giant granulated histiocytes (ggh) and non-granulated giant histiocytes (gh). Other atypical forms are “hand-mirror” PC, trinucleate and binucleate PC resembling cells seen in multiple myeloma (MM) and lymphomas. Collectively these PC variants constitute “reactive plasmatosis” (RP) likely arising as a consequence of the presence of various bacteria including Streptococcus and E. coli. The conclusions: It is demonstrated that RP as occurs in lame ducklings suffering from bacterial infections, provides a unique theater for the study of PC variability. Atypical PC, some resembling neoplastic types, were common in RP BM. The significance of the study relates to the importance of PC in disease and immunity; therefore, these observations should interest those who specialize in these areas. They expand the knowledge of avian plasmacyte morphology.

Di Kelurahan Karangbesuki, Kota Malang, ditemukan banyak arsip buku Letter C yang telah usang dan belum pernah diperbarui, sehingga dikhawatirkan dokumen dapat rusak dan data yang ada di dalamnya akan hilang. Selain itu, sistem pembukuan yang masih manual juga menyebabkan pelayanan yang diberikan juga membutuhkan proses yang lama. Solusi yang ditawarkan pengabdi adalah membuat aplikasi buku Registrasi Desa/Kelurahan (Letter C) berbasis website. Pembuatan aplikasi ini dilakukan melalui tiga tahap, yaitu tahap persiapan berupa identifikasi kebutuhan teknologi dan informasi data pertanahan, tahap pelaksanaan berupa perancangan dan pengembangan aplikasi serta pembuatan buku panduan penggunaan aplikasi, dan tahap evaluasi berupa pelatihan kepada administrator aplikasi dan pemeliharaan aplikasi. Dari hasil uji coba aplikasi dan pelatihan kepada administrator, setiap fitur dapat diakses dan digunakan sesuai dengan fungsinya. Selain itu, data persil yang terdapat dalam buku Registrasi Desa/Kelurahan (Letter C) juga sudah dimasukkan ke dalam aplikasi dan siap digunakan oleh pihak Kelurahan Karangbesuki. Diharapkan pelayanan Kelurahan Karangbesuki di bidang agraria dapat berjalan lebih efektif, efisien, dan terpadu.

Hurricane Ida ferociously affected many south-eastern and eastern parts of the United States, making it one of the strongest hurricanes in recent years. Advanced forecast and warning tool has been used to track the path of the ex-Hurricane, Ida, as it left New Orleans on its way towards the northeast, accurately predicting significant supercell development above New York City on September 01, 2021. This advanced method accurately detected the area with the highest possible level of convective instability with 24-h lead time and even Level 5, devised in the categorical outlooks legend of the system. Therefore, an extreme level implied a very high probability of the local-scale hazard occurring above the NYC. Cloud model output fields (updrafts and downdrafts, wind shear, near-surface convergence, the vertical component of relative vorticity) show the rapid development of a strong supercell storm with rotating updrafts and a mesocyclone. The characteristic hook-shaped echo signature visible in the reflectivity patterns indicates a signal for a highly precipitable (HP) supercell with the possibility of tornado initiation. Open boundary conditions represent a good basis for simulating a tornado that evolved from a supercell storm, initialized with initial data obtained from a real-time simulation in the period when the bow echo and tornado-like signature occurred. Тhe modeled results agree well with the observations.

Published: February 2022

The efficiency and irreversibility defined based on the second law ofthermodynamics provide a new path for heat exchangers design and makeperformance analysis more straightforward and elegant. The second lawof thermodynamics is applied in a Straight Microchannel Printed Circuitheat exchanger to determine the thermal performance of different shapes ofBoehmite Alumina compared to Al2O3 aluminum oxide. The various formsof non-spherical Boehmite Alumina are characterized dynamically andthermodynamically through dynamic viscosity and thermal conductivity,using empirical coefficients. The non-spherical shape includes platelet,cylindrical, blades, and bricks forms. Graphical results are presented forthermal efficiency, thermal irreversibility, heat transfer rate, and nanofluidexit temperature. The non-spherical shapes of Boehmite Alumina showdifferent thermal characteristics concerning the spherical shape whenthere are variations in fluid flow rates and the nanoparticles fraction.Furthermore, it was theoretically demonstrated that non-spherical particleshave higher heat transfer rates than spherical particles, emphasizingplatelets and cylindrical shapes for the low volume fraction of nanoparticlesand bricks and blades for high volume fraction.
STUDI KRITIS TERHADAP PEMIKIRAN MAHMUD MUHAMMAD TAHA TENTANG KONSEP NASAKH AL-QUR’AN
Authors: Fikri Muhammad Al , Mustaniruddin Ahmad
Published: February 2022

This article discusses one of the topics of the study of the Qur'anic science which was developed by one of the contemporary thinkers, namely Mahmud Muhammad Taha. He considered that the Islamic teachings contained in the madaniyah verses were irrelevant at this time because they contained values ​​that were less tolerant and even radical. Meanwhile, the Makiyah verses contain fundamental values ​​such as justice, equality, tolerance, democracy, and human rights. So, according to him, madaniyah verses need to be replaced with these makiyah verses. With such an inverted nasakh concept, he wants to carry out an evolution of sharia where according to him sharia is something historical that can change according to the situation and conditions that require it. The concept of nasakh al-Qur'an developed by Taha is different from the concept of nasakh agreed upon by the majority of scholars. Therefore, based on the critical analysis in this article, it can be said that the nasakh Taha concept still has a number of epistemological problems so that it is not valid for use in interpreting the verses of the Qur'an.

 

Artikel ini mendiskusikan tentang topik kajian ilmu al-Qur’an yang dikembangkan oleh salah satu tokoh pemikir kontemporer yaitu Mahmud Muhammad Taha. Ia menilai bahwa ajaran Islam yang terkandung dalam ayat-ayat madaniyah tidak Sesuai dengan nilai – nilai kemanuasiaan dan masyarakat modern karena ayat madaniyah mengandung nilai radikalisme dan berlawanan dengan hak asasi manusia. Sementara ayat-ayat makiyah berisi tentang nilai-nilai fundamental seperti keadilan, kesetaraan, toleransi, demokrasi, dan HAM. Sehingga, menurutnya, ayat-ayat madaniyah perlu di-nasakh dengan ayat-ayat makiyah tersebut. Dengan konsep nasakh terbalik seperti demikian ia ingin melakukan evolusi terhadap syariat di mana menurutnya syariat merupakan sesuatu yang bersifat historis yang dapat berubah sesuai situasi dan kondisi yang menghendakinya. Konsep nasakh al-Qur’an yang dikembangkan oleh Taha tersebut berbeda dengan konsep nasakh yang disepakati oleh mayoritas ulama. Oleh karena itu, berdasarkan analisis kritis dalam artikel ini dapat dikatakan bahwa konsep nasakh Taha tersebut masih terdapat sejumlah permasalahan epistemologis sehingga tidak valid untuk digunakan dalam penafsiran al-Qur’an.

Surfaktan adalah zat yang ditambahkan pada cairan untuk meningkatkan sifat penyebaran atau pembahasan dengan menurunkan tegangan muka. Banyak industri menggunkan surfaktan antara lain sebagai emulsier, corrosion inhibition, defoaming, emuliency, dan lain lain. Pada penelitian ini mencoba memanfaatkan jerami padi sebagai bahan baku pembuatan surfaktan sodium lignosulfoant dikarenakan kandungan lignin yang cukup besar. Selain itu bahan baku yang relatif murah tentunya akan memberikan nilai ekonomi yang cukup tinggi dan juga dapat mengurangi pemanfaatan surfaktan berbahan baku minyak bumi. Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi larutan pemasak NaHSO3dan waktu pemasakan, serta menentukan kualitas dari surfaktan. Penelitian ini dilakukan dengan menggunakan reaktor labu leher tiga dengan rasio variasi konsentrasi larutan pemasak  NaHSO3(50%, 60%, dan 70%) dan waktu pemasakan (90, 120 dan 150) menit pada temperature 900C, pH 4, ukuran jerami padi 200 mesh dan Kecepatan pengadukan 80 rpm. Berdasarkan hasil penelitian didapatkan surfaktan natrium Lignosulfonat paling tinggi dengan karakteristik yang sesuai standart surfaktan alkyl benzene sulfonate yang dijual dipasaran pada waktu pemasakan 150 menit dan konsentrasi larutan NaHSO370% dengan kriteria sebagai berikut : Berbau Sulfur dan agak asam, warna kuning kecoklatan, pH 5, dan larut sempurna dalam air. Semakin lama waktu pemasakan dan semakin tinggi konsentrasi larutan NaHSO3 maka semakin besar pula kadar natrium lignosulfonat yang didapat. Berdasarkan analisa dengan spektrofotometer didapat kadar natrium surfaktan lignosulfonat yang maksimum yaitu 40,6047 ppm, dengan absorbansi 1,0823 nm.
