Published: February 2022

En población general, un estudio realizado en 19 países encontró una media de reticencia del 28,5%. En general, la principal preocupación es el riesgo de efectos adversos, basado especialmente en la difusión de noticias falsas. Una revisión de 126 encuestas realizadas durante el año 2020 abarcando 31 países ha mostrado que las actitudes en torno a la vacunación han fluctuado durante el año según la intensidad de la pandemia en el momento de la ejecución de la encuesta, y en general presentan diferencias relacionadas con desigualdades socioeconómicas y afiliaciones políticas, además del deseo de esperar a que otros se vacunen previamente. La metodología utilizada para el presente trabajo de investigación, se enfoca hacia una metodología orientada hacia la necesidad de indagar en forma precisa y coherente una situación. Enmarcada dentro de una revisión bibliográfica de tipo documental, ya que nos vamos a ocupar de temas planteados a nivel teórico como es La influencia de las redes sociales en el proceso de vacunación ciudadana por COVID-19. La técnica para la recolección de datos está constituida por materiales impresos, audiovisuales y electrónicos, estos últimos como Google Académico, PubMed, entre otros. La información aquí obtenida será revisada para su posterior análisis. Hay que aclarar que, dentro de los trabajos de investigación revisados e analizados para desarrollar este texto, no hubo evidencia clara o directa dentro de los instrumentos aplicados, que las personas que tienen una predisposición a vacunarse, hayan tomado esa decisión a causa de las redes sociales o medios de comunicación, ya que es una pregunta que formalmente no se ha realizado. Sin embargo, dentro de las respuestas de las personas que tienen temor a la vacuna por un tema de efecto adverso, seguridad de la vacuna y la rapidez en que fueron creadas, sin duda alguna, son respuestas comunes dentro de los grupos anti vacunas en el mundo, que se han ido difundiendo tanto en los medios de comunicación como las redes sociales.

Credit take over is a payment made by a third party to a creditor, who will replace his position as a new creditor to the debtor. The absence of standard rules regarding the implementation of credit take over has resulted in non-standardization of the credit take over implementation process. The purpose of this article is to examine the legal protection of the parties in implementing the take over at Bank Jatim Banyuwangi Branch. This type of research is empirical legal research where the study was conducted at Bank Jatim Banyuwangi Branch. The results of research conducted by a Notary/PPAT in Banyuwangi are included in the category of subrogation by way of law (Article 1403 of the Civil Code). In the implementation of take over credit protection is obtained through the re-signing of the SKMHT at the time of the Roya Letter, and a certificate of proof of ownership of the guarantee has been physically issued by the initial creditor. The implementation of the take over for new creditors at Bank Jatim Banyuwangi Branch is obtained through the re-signing of the SKMHT which is the basis for making APHT when the roya letter, proof of credit repayment, and certificate of proof of collateral ownership have been physically issued by the initial creditor (bank). The initial check before the certificate of proof of ownership is issued by the initial creditor is carried out by issuing a Land Registration Certificate (SKPT) through the BPN.How to cite item: Firmansyah, F.

Published: February 2022

In 2020, the President of Indonesia established Presidential Regulation Number 99 of 2020 concerning the Procurement and Implementation of Vaccinations to Annihilate Covid-19 Pandemic. Furthermore, this Presidential Regulation was amended by Presidential Regulation Number 14 of 2021 which contained a particular provision to impose legal sanctions on people who violated rules by do not participate in Covid-19 vaccination. Administration sanctions such as postponing or terminating social security awarding or social assistance will be imposed on a citizen who does not comply with that particular provision. This kind of administrative sanction will potentially harm the rights of lower classes people. This study is to analyze the ambiguity of legal sanctions against people who refuse to get Covid-19 vaccination and to analyze the alternative solution to take out the ambiguity of imposing sanctions on people who violated these particular rules. This research method uses normative legal research by statutory and conceptual approach. This study concludes that the ambiguity caused by those sanctions is contradicted with the legislation rules and principles. Therefore, social work sanctions can be used as an alternative solution to substitute administrative sanctions that cause ambiguity and violated the community’s rights.How to cite item: Nasution, A., Setiadi, W., Nahuddin, Y.

For customers, internet banking service facilities provide the advantage of being able to make online payments. Internet banking also provides accommodation for banking activities through computer networks anytime and anywhere quickly, easily, and safely because it is supported by a strong security system, especially for those who are always busy managing their finances. As for the formulation of the problem in this paper, how is the use of the principle of freedom of contract in standard contracts on internet banking seen from the point of view of Law Number 8 of 1999 concerning consumer protection and what is the legal protection for internet banking users for the contents of the standard contract? The result of this research is that the standard agreement on internet banking in its contents must be in accordance with the legal bases and articles that have been regulated in Law Number 8 of 1999 concerning Consumer Protection, where the agreement is not allowed if it harms the party implementing the agreement standard which in this case is a customer or debtor and the Bank is responsible for carrying out all obligations contained in the Banking Act, also in the Consumer Protection Act. The bank is also responsible for losses suffered by customers, whether they arise due to system errors or due to errors made by bank officers. A bank can only be released from its responsibilities after fulfilling its performance and paying compensation to the customer, or if the loss is due to the customer's fault or due to a compelling situation.How to cite item: Janitra, S., Ghufron Az, M., Wisnuwardhani, D.

Published: February 2022

The conceptual model "Phytosanitary optimization of agrophytocenoses" involves monitoring the crops of the main agricultural crops. The purpose of monitoring is to determine the core of the most harmful weed plant species, as a basis for the development of an integrated plant protection system. The object of the research was the process of community evolution in zea mays agrophytocenoses, in the conditions of the south of the Nonchernozem zone. Geobotanical materials were analyzed on the rounds of surveys of corn crops.  The work used an experimental method - field ecological surveys, and theoretical research methods - information analysis and mathematical statistics (Jaccard index, S?rensen coefficient, Spearman's rank correlation coefficient, Kendall rank correlation coefficient). The monitoring carried out proved that over the 90-year period of cultivation, a core of weediness was formed, based on annual late spring weeds, which were absent during the period of extensive farming. The group of creeping perennial weed remained unchanged in all the years of the surveys; this feature must be taken into account when developing a system of protective measures. At present, agrophytocenoses contain the most harmful rhizome and creeping perennial weed, early spring and late spring species.

Optimization of the irrigation rate of agricultural crops based on the use of energy resources
Authors: Khozhanov Nietbai Nurzhanovich , Bezborodov Yuri Germanovich
Published: February 2022

The results of methodological studies on the calculation of the total water consumption and irrigation rate of agricultural crops, based on the analysis of the use of energy resources, the radiation balance of the arid zone of the Republic of Kazakhstan are presented. It is proposed to determine the actual total water consumption and the size of the irrigation norm of agricultural crops through the radiation coefficient of the area (KRd), which is determined by the functional dependence with the total lack of air humidity for the growing season (?d) and the radiation indicator of a specific area (R). The dimensions of irrigation norms obtained as a result of calculations are on average 838.9 m3/ha, which is 76.40-83.90 m3/ha higher than the experimental data calculated according to the formula of A. N. Kostyakov. The dimensions of the irrigation norm calculated at the Kordai, Taraz, and Tyuken weather stations are lower than the experimental data. The established fact gives reason to believe that for many years insufficient justification for the appointment of irrigation standards, and, consequently, the saving of irrigation water contributed to the degradation of irrigated massifs. The calculations of the total water consumption according to the indications of 6 regional weather stations were carried out. The calculation of the total water consumption indicator by the absolute mark does not differ from the calculated one by the method of S. M. Alpatiev by more than 10%. The same difference is shown by the calculation of the total water consumption indicator for the radiation indicator. The calculations of the radiation coefficient of the area show that there are energy opportunities to optimize not only irrigation norms and irrigation regime, but also the entire farming system of the arid zone of the Republic of Kazakhstan, which are primarily due to the imperfection of the operated irrigation systems, low quality of irrigation and other reasons.
Species diversity and productivity of pasture lands ecosystems on sandy soil
Authors: Vlasenko MarinaVladimirovna
Published: February 2022

The results of monitoring studies carried out to identify the features of the current distribution of vegetation and productivity of sandy pasture ecosystems in the south of the European territory of Russia are presented. The objects of research were natural pasture phytocenoses on the territory of the Tsimlyansk sand massif. The methods of ecological and geobotanical surveys were used in the work. Plant samples were collected at key sites located in different wet areas using the 5-fold slope method. To identify dominant and subdominant species of natural phytocenoses, the Drude species abundance assessment scale was used. It was found that the pasture ecosystems of the Tsimlyansk sand massif are characterized by the presence of 58 dominant and subdominant species from 22 families, which occupy a certain position in the herbaceous and shrub communities, depending on the moisture content of the territory. The territory of complete humidification is characterized by the presence of 7 dominants and subdominants from 7 families. In the territory of excessive moisture, 9 species from 7 families dominate in phytocenoses. On the territory of sufficient and variable moisture, 26 species from 8 families predominate in the communities. The territories of moderate humidification are distinguished by the presence in the associations of 22 dominant species from 9 families. The territory of complex moistening, which is insufficient and severely insufficient under sand hills and moderate in the groves, is characterized by the presence of 9 dominant and subdominant species from 6 families in the communities. In 2018-2020 it was revealed that the annual phytomass of the grass and grass communities of the Tsimlyansk sand massif increases from spring to summer (from 91-117 to 204-267 g/m2) and decreases from summer to autumn (from 204-267 to 156-190 g / m2). The average annual productivity of natural phytocenoses is 156-190 g / m2.

According to experience, a high seed yield was obtained when cultivating the Benefit variety, placed with a row spacing of 45 cm according to the predecessor spring wheat. The yield of gross energy in the crop per a. s. v. was in the range from 15.75 to 70.58 GJ/ha; the yield of grain per 1 GJ of energy consumption was from 0.06 to 0.26 tons. The highest values in the experiment were noted in the large-seeded variety Benefit, low values - in the small-seeded variety Sokol. Under the conditions under consideration, the best indicators of bioenergetic efficiency of seed production were characterized by the following varieties: large-seeded Benefit (with row spacing of 45 cm and 60 cm for the predecessors spring wheat, grain sorghum and corn) and Bonus (with row spacing of 45 cm for the predecessor spring wheat); medium-seeded Sphere (with row spacing of 45 cm for the predecessor spring wheat), due to the combination of high yield and grain quality.

Gestosis develops when the adaptive systems of the cow body is unable to create the necessary conditions for the developing fetus. The research goal is to reveal the relationship between the biochemical, hormonal and immune indices and the incidence of postpartum complications in cows. The studies were carried out in 2019 in the Black-Pied herd; 104 cows 60-10 days before calving were studied. The trial group consisted of 43 cows with postpartum complications (postpartum endometritis, retained placenta and parturient paresis); the control group consisted of 61 cows with a physiological course of calving and the postpartum period. There is a strong inverse statistically significant relationship between the concentration of estradiol in blood serum 15 days before calving and retained placenta cases (rs=-0.75; ?<0.05). A close inverse statistically significant relationship was found between the progesterone concentration in cows 15 days before calving and retained placenta cases (rs=-0.72; ?<0.05). The concentration of HDL-cholesterol is strongly negatively associated with the occurrence of parturient paresis (rs=-0.97; ?<0.01). Regarding the levels of alkaline and placental-like alkaline phosphatase in blood serum of cows 45 days before calving, a close direct relationship was found with retained placenta cases (rs=0.67; ?<0.05 and rs=0.88; ?<0.01). A strong positive, statistically significant relationship was found between the value of the neutrophil functional reserve and the cases of postpartum pathologies as retained placenta (rs=0.76; 0.83) and endometritis (rs=0.69; 0.79).

Published: February 2022

The technological processes that are used in the world allow us to mechanize many stages of hazelnut production, ranging from microclonal propagation of planting material to fruit harvesting and processing. Especially valuable in this process is that for the production of hazelnuts, you can also use areas that are not quite suitable for growing other field and garden crops, Despite the fact that the costs of cleaning and protecting plants from pests increase, since you have to use only manual work, but such plantings prevent or minimize the effects of erosion processes, binding the soil on the slopes with their roots and do not allow it to wash away.

Published: February 2022

The purpose of the research was to compare the effectiveness of nanopreparation Nutrivant Plus and trace elements on the growth, development and yield of flax. The experiment was conducted in 2017-2018 on the field of the Smolensk State Agricultural Academy. The object of the study was the flax variety S-108, zoned in the Smolensk region and bred in the Smolensk Research Institute of Agricultural Sciences (former Smolensk State Agricultural Stantion). According to the results of the experiment, it was found that trace elements and nanopreparation increased the germination of flax seeds to 93.6 %. The density of standing plants and their number before harvesting in the variants with the use of trace elements was higher than when using nanopreparation. Treatment of flax seeds with solutions of trace elements to a greater extent contributed to an increase in the yield of flax products. The largest increase in flax straw was obtained from wetting the seed material with iron and zinc sulfate – 3.2 – 4.2 t/ha (53-70 %); for flax fiber – 0.8 – 1.1 t/ha (89 – 122 %). The highest yield for seeds was obtained from treatment with nanopreparation, the increase relative to the control was 0.2 t/ha or 67 %. To achieve high profit and profitability in the cultivation of flax, it is advisable to combine seed treatment before sowing (wetting) with 0.05 % water-dispersed suspension nanopreparation of Co and Fe.

Using hybridological and isogenic analyzes, the allelicity of genes controlling the shape of reed flowers in four nearly isogenic lines of sunflower was studied. It was found out that the recessive alleles fs and fn, which control short and narrow ligulate flowers, respectively, belong to different loci, and the fs and fn alleles interact with each other in a complementary manner. The recessive alleles fn and ftw, which control narrow and curled reed flowers, respectively, belong to different loci, and the fs and ftw alleles interact with each other in a complementary manner. The recessive alleles fn and ft controlling, respectively, narrow and tubular reed flowers belong to different loci, and the fn and ft alleles interact with each other in a complementary manner. These recessive genes can be used to breed new varieties and hybrids of ornamental sunflower, as well as to mark varieties and hybrids of oilseed, roasted, confectionery and silage sunflowers.

The article presents the results of field experiments carried out in 2018-2020 on the fields of EkoNivaAgro LLC at the Levoberezhnoye farm (Liskinsky district, Voronezh region). The objects of the study were the Canadian soybean variety OAK Prudence, the Argentinean inoculant of the liquid formulation Nitragin Zh, the fungicidal dressing agent Delit Pro, KS, pyraclostrobin 200 g / l (BASF, Germany). Soybeans were grown using the NO-TILL technology after the predecessor corn for grain. The yield of soybean grain in the control variant (without the use of agrochemicals) was the highest in 2018, favorable for moisture (1.50 t / ha) and practically the same in 2019 and 2020. - 1.24 and 1.23 t / ha, respectively. On average for 2018–2020 the yield of soybean grain in the control variant was 1.32 t / ha. The maximum grain yield was obtained on the variant with the combined use of the inoculant Nitragin Zh and ammonium nitrate at a dose of 200 kg / ha - 2.08 t / ha. The increase in comparison with the control variant reached 0.76 t / ha, or 57.0%. The greatest influence on the technological parameters of soybean seeds was exerted by pre-sowing inoculation of seeds and pre-sowing application of nitrogen fertilizers at a dose of N70. Inoculation provided an increase in the protein content in soybean seeds by 4.1%, and the introduction of N70 by 4.3% in absolute terms compared to the control.
