Published: July 2021

The influence of plant nutrition area and mineral fertilizer rates on the productivity of St. John's wort (Hypericum perforatum L.) by using transplant reproduction method in the conditions of drip irrigation was studied. It was proved that the transplant method of cultivation of St. John's wort under drip irrigation is a very effective method of reproduction of this crop. Four variants of planting density per unit area were studied: 42 thousand plants / ha (cultivation scheme 60x40 cm), 56 thousand plants / ha (60x30 cm), 83 thousand plants / ha (60x20 cm) and 167 thousand plants / ha (60x10 cm). Yield recording of raw materials (air-dry tops) was carried out in the phase of mass flowering. In the first year of vegetation this period was in the first decade of August, in the second year – in the second decade of June. It was found that the increase in the number of planted plants of St. John's wort per 1 ha contributed to the increased plantation productivity. When having a cultivation plant density of 42,000 plants / ha, the yield of dry grass in the first year of vegetation was 3,02 t / ha. Increasing the number of plants to 56 thousand plants / ha provided 3,26 t / ha of raw materials. The highest yield of dried St. John's wort – 3,76 t / ha in the first year of vegetation was obtained in the variant with the largest number of planted plants per unit area - 167 thousand plants / ha. In the second year of vegetation of St. John's wort in the variant with the lowest plant density of 42 thousand plants / ha, the yield was 3,65 t / ha. The most productive plantation of the second year of vegetation was in the variant with a plant density of 83 thousand plants / ha, where the yield of dry raw materials was 3,96 t / ha. A further increase in the number of plants per unit area led to a decrease in crop yields. The influence of four variants of the main application of mineral fertilizers on the productivity of St. John's wort was also studied: N0P0K0 (reference), N60P60K60, N120P120K120 and N180P180K180. It was found that with increasing fertilizer application rate, the yield of dry raw materials increased. The most favorable conditions for growth and development of plants of St. John's wort developed in the variant with the maximum rate of fertilizer application - N180P180K180, where the yield of dry raw materials in the first year was 3,31 t / ha, and in the second year – 4,15 t / ha, which exceeded the reference result (without fertilizers) by 0,61 t / ha and 0,84 t / ha, respectively.

Published: July 2021

Ukraine is located about at the latitude of France, the northern part of the United States and southern Canada and has similar to these countries natural conditions. Different in terms of soil and climate conditions, the regions of agriculture in Ukraine can be considered as analogues of similar natural conditions of agricultural areas in other parts of the world. Soils with a high carbon content are more productive and able to better filter and purify water. Water contained in the soil serves as a moisture source for 90% of world agricultural production. One of the main areas of research is the study of the ratios of main products and by-products of yield, as well as root and plant residues when having different soil fertility and using promising varieties and hybrids of crops. The use of optical express methods should be carried out according to the stages of organogenesis of field crops, which will enable to specify the relationships between them, to develop criteria and indicators for effective regulation of nitrogen and carbon cycle in the system "soil - plant - atmosphere", to develop models of formation and transformation of root and other plant residues taking into account changing agrometeorological factors, crop rotations, features of the branch structure of agricultural production, varieties and hybrids of field crops. In the future, this will enable to determine the areas in the selection aimed at accumulating root mass and achieving garanteed deficit-free balance of organic carbon in the soil. The research will enable to purposefully and effectively regulate the cycle of carbon and nitrogen, both at the level of individual agricultural production systems and on the scale of the same type of agricultural areas and regions, taking into account the whole set of variables, including features of the sectoral structure of production, climate change, etc.

Relevance of research. In the area of ​​irrigated agriculture, one of the most difficult as to developing flooding processes is the area of ​​terrace drift within the ancient delta of the Lower Dnieper in Kherson region. The terrace area is located on a flat area within a large drainless bowl about 40 km long and up to 5-10 km wide. On the surface of the bowl there are large drainless depressions (Chornyanske, Novomayatske, Podokalynivske, Tarasivske) and many small ones.
The purpose of the work is to establish the patterns of developing flooding processes and substantiate a system of reliable protection of the territory against that in difficult natural and water conditions.
Methods and objects of research. The research was conducted at the research and production site located near Tarasivka village, Oleshkiv district, Kherson region. The results of the research were based on the data of reconnaissance surveys, long-term observations on the depths of the groundwater table (GWT), precipitation, space images, etc. In addition, it was assumed that the area is considered to be flooded if the depth of the GWT exceeds the critical limit, which for the study region is defined as 2 m.
Research results and main conclusions. In modern conditions, part of the village and adjacent lands are subject to constant groundwater flooding and periodically surface water flooding. In the central part of the village, groundwater depths exceed the critically acceptable depth, which for the study region is defined as 2 m. The water and ecological situation in the village is significantly exacerbated in wet periods. Current development of flooding within the terrace requires the development and implementation of a more effective protection system. One of the important options for protecting the village territory is the construction of a horizontal drainage system, which is set up in the village and its surroundings. The depth of drainage is 3.0-3.2 m. The runoff is discharged into the North-Crimean Canal by means of a pressure pipeline. The surface drainage system should be represented by a network of trays and ditches arranged in the streets of the village and a collector, which provides self-flowing of excess water into an artificial reservoir - pond. Options for the reconstruction of the NCC, which provide for using the drainage capacity of the canal and the construction of a regional self-flowing reservoir, were addressed. The modernization of irrigation and drainage systems and implementation of the developed proposals will significantly increase the protection level of the ancient terrace of the Dnieper River against the harmful effects of water. The decision on a proposal is made on the basis of feasibility study.
Modern aspects of scientific support for the restoration of drainage systems in the humid zone of Ukraine

Published: July 2021

Modern aspects of scientific support for the restoration (reconstruction and modernization) of drainage systems in the humid zone of Ukraine were determined, which were established based on the results of the analysis of the current state and features of drainage systems functioning. One of the priority areas is the development of a scientific justification of improving water supply for drainage systems. The most effective and economical technological method of increasing the water supply in reclaimed areas is the accumulation of local drainage runoff. Given the shortage of local drainage and surface runoff, increasing the water supply in reclaimed areas is provided by withdrawing and supplying to reclamation systems extra water volumes from existing reservoirs, rivers, ponds, lakes, located both within and beyond the systems. The current structure of agricultural use of drained lands in the humid zone is subject to both climate change and export market conditions. In agricultural production such crops as grain corn, sunflower, rapeseed, soybeans are cultivated. Changes in the use of drained land should be taken into account when justifying the reconstruction or modernization of drainage systems. This will enable to develop and implement a set of measures for technical re-equipment and reconstruction of drainage systems, introduce advanced resource-saving technology for growing economically attractive crops and ensure effective water regulation on drained land sin accordance with the requirements of agricultural production. The technical state of modern drainage systems in the humid zone is mainly characterized by two conditions: satisfactory, when the systems are under operation (operational) and can perform their functions keeping the design mode, and unsatisfactory, when the restoration of drainage systems is only possible provided modernization measures. Given climate change, the priority measures for the modernization of drainage systems should include work to expand their functionality to regulate soil water regime throughout the growing season. In view of the cost of modernization to expand the functionality of different types of systems (drainage, drainage and irrigation, polder and water circulation) by constructing irrigation systems on them is much lower compared to modernize them to drainage and irrigation ones when using sluice technology, preference should be given namely to the construction of irrigation systems.

The article presents the results of the research on soil bulk density and permeability as well as weediness of maize crops at the beginning and end of growing season on average for 2016-2019, applying different basic tillage and fertilizer systems. The goal of the research was to determine the effect of different methods and depth of basic tillage and fertilizers on agrophysical properties of soil and crop productivity in grain-row crop rotation when irrigating in the south of Ukraine. The objective of the research was to determine the effects of different methods and depths of basic tillage as well as fertilization on the agrophysical properties of dark chestnut soil and the productivity of corn in short crop rotation. During the experiment, field, quantitative-weight, visual, laboratory, calculation-comparative, mathematical-statistical methods and generally accepted in Ukraine methods and methodical recommendations were used. The research was conducted in the research fields of the Askanian SARS IIA NAAS of Ukraine.
Based on the research results it was established that, both at the beginning and at the end of grooving season when applying the tillage up to 28-30 cm within the system of differentiated tillage bulk density was the smallest as 1,14 g/cm3 when using green manure and 1,19 g/cm3 without its use. When applying subsurface different depth tillage, bulk density increased up to 1,18 g/cm3 when using green manure and up to 1,26 g/cm3 without its use. Maximum bulk density of 1,28 g/cm3 was observed when no tillage applied without using green manure and 1,31 g/cm3 when using it that is by 12,3 and 10.1% higher compared to the reference area, respectively. The highest corn productivity was observed when applying subsurface different depth tillage, where the average values by the factor A were about 10,93 t/ha that is higher than those obtained in the reference area by 0,52 t/ha, or 5,0%. The use of zero tillage caused the obtaining of the lowest yield in the experiment as 8,71 t/ha that is less compared to the reference area by 1,7 t/ha, or 19,5%.

Authors: Yakubu Abubakar 
Published: July 2021

A Comparative analysis of practices obtained between the Pondok and Tsangaya with regard to traditional Islamic education and spirituality in Malaysia and Nigeria, indicates that, despite areas of similarity in origin and evolution, there exist a unique area of sharp contrast in relation to later life spirituality and elder care. The article maintains that, despite the two systems sharing wider similarities of originating from the traditional system of Arabic and Islamic education, the Pondok provides a complete platform for the spiritual life cycle, with opportunities for devotion from childhood to death. The Tsangaya on the other hand, covers childhood to early adulthood, thus, presenting a halfway approach to the spiritual life cycle. Recommendations were based on the need for the Tsangaya to model along aspects of the Pondok in a manner that will enable the incorporation of later life spiritual needs of the elderly. The purpose of this article is to carry out a comparative analysis of these two systems of traditional Islamic education , in relation to eldercare and spiritual wellbeing. The relevance of this paper lies in the fact that population aging is currently receiving attention as global crises, and issues of elderly wellbeing in all aspects are being explored towards addressing the needs of the elderly.

Published: July 2021

Background: Uterine leiomyosarcoma is a rare gynecological disease. Myxoid leiomyosarcoma (mLMS) is an aggressive and very uncommon type of leiomyosarcoma, with few cases reported in English literature. Stromal metaplasia is rare in leiomyosarcoma. Here we present huge uterine myxoid leiomyosarcoma with stromal chondroid metaplasia. Case Report: A 48–year–old single woman with lower abdominal pain and increased abdominal circumference. The detected mass on imaging was diagnosed as uterine mLMS with stromal chondroid metaplasia in the histopathological examination after surgery. Conclusion: Myxoid leiomyosarcoma should be considered in uterine mass with extensive myxoid change, infiltrative border, low mitotic count, and mild atypia. Stromal chondroid metaplasia can be seen in the myxoid leiomyosarcoma. [GMJ.2021;10:e1817]
Relationship Between the Journal Self-Citation and Author Self-Citation and the Impact Factor in Iranian, American, and European Institute for Scientific Information Indexed Medical Journals in 2014-2021
Authors: Jamalnia Sheida , Shokrpour Nasrin 
Published: July 2021

Background: Author and journal self-citation contributes to the overall citation count of an article and the impact factor (IF) of the journal in which it appears. However, little is known about the extent of self-citation in the general clinical medicine literature. This study aimed to determine the effect of self-citation (journal and author) on the IF of Iranian, American, and European English medical journals. Materials and Methods: IF, IF without self-citations (corrected IF), journal self-citation rate, and author self-citation rate for medical journals were investigated from 2014–2021 by reviewing the Journal Citation Report (JCR). Twenty Iranian medical journals (published in English) in the web of science indexed were selected and compared with 20 American and 20 European medical journals. The correlation between the journal self-citation and author self-citation with IF was obtained. We used Spearman’s correlation coefficient for the correlation of self-citation and IF. Results: The overall journal citations were higher in the American and European journals compared to the Iranian ones between 2014 and 2021. There was a significant relationship between journal self-citation rates and IF (P<0.001). The findings demonstrated that the rate of author self-citation was higher in the European and American journals compared to the Iranian ones. Findings also showed a significant difference between the author's self-citation and IF in Iranian, American, and European medical journals that published in English (P<0.001). Conclusions: The self-citation rate positively affects the IF in medical journals. A high concentration of self-citation of some journals could distort the ranking among medical surgery journals in general.

Published: July 2021

Hombre de 56 años, sometido a gastroplastia endoscópica hace 8 meses, evolucionando con la recuperación de peso. El paciente presentaba como comorbilidades: una dislipidemia, hipertensión arterial sistémica y apnea del sueño, antes del procedimiento tenía una BMI de 38,74 Kg/m2, con un peso estimado de 122 kg. El aumento de peso de 14 kg fue más evidente en los últimos 2 meses. Sometido a una tomografía computarizada abdominal mostró una cámara gástrica preservada (Figura 1).
Aunque de la apertura de los puntos en la pared gástrica, existe una restricción de la distensión de la cámara gástrica, puede ser responsable de la saciedad temprana, lo que hace que el paciente mantenga la pérdida de peso. La técnica endoscópica consiste en un endoscopio que se inserta a través de la cavidad bucal hasta el estómago, donde se despliega una serie de suturas.
Las suturas se colocan comenzando desde la parte pilórica y luego moviéndose gradualmente hacia el fondo gástrico1. En la técnica de gastroplastia se utiliza una aguja curva e hilo de polipropileno 2-0, rodeando la pared gástrica con una profundidad de 15 mm. Las suturas ceñidas crean una línea de pliegues en la pared del estómago, reduciendo radicalmente el volumen gástrico. 2

Background: To explore the influences of pharmaceutical companies on prescription practices and to find out types of incentives of pharmaceutical companies on medical doctors in private and public hospitals in Islamabad, the capital city of Pakistan
Methods: A qualitative exploratory study was conducted in 06 months May-Oct: 2017 in Islamabad (Capital City of Pakistan). Data were collected from doctors and pharmaceuticals representatives through snowballing sampling techniques through open ended questionnaire in which In-depth interviews were taken. In depth interviews were recorded, transcribed and coded. Qualitative sub-component was included to triangulate the data, sub themes and themes were generated.
Results: Respondent’s prescription is a basically document in which we suggest minimum effective medication therapy to the patient, that is also cost effective and give maximum treatment to the patient. Few of the respondents are also agreeing on the point that most of the times patient itself influences to prescribe the particular product. Patient itself influences to prescribe the particular product that is redundant in its treatment regimen. Other respondents stated that prescription is varying from patient to patient and our priority is to give the medicine to the patient which shows good efficacy.
Conclusion: Most doctors were maintaining protocol of prescription and using brand name of medicine. Pharmacists were visiting them on regular basis conditionally.
