Authors: Dasweptia Dasweptia , Hamdani Agung Satria , Kurniawan Tommy
Published: February 2023

Lightning strikes on airborne transmission networks such as in distribution lines are injections of electric charge. The injection of the charge will cause a voltage increase in the network, so that more tension will arise in the network. Lightning Arrester (LA) is one of the equipment in the protection system to protect the 20 kV distribution transformer against overvoltage coming from lightning strikes. Under normal circumstances LA acts as an insulator, but when exposed to lightning strikes LA will function as a conductor whose resistance is relatively low, so that it can flow the surge current to the ground. This study aims to see the effect of the placement of lightning arresters before and after fuse cut out on overvoltage in the 20 KV distribution transformer, so that which placement is better is obtained, taking into account factors that affect the level of voltage and overcurrent that occurs in each system such as the location of LA placement, the steepness of incoming waves, the speed of propagation of surja waves, the voltage is large through the protection system, and the Basic Insulation Level (BIL) value of the equipment. So that in the end, the right PLACEMENT of LA was obtained as a 20 kv distribution transformer protection. Based on the results of the study, the voltage that reached the transformer was 67,192 kV, in this condition the transformer was still in a safe state because the voltage hitting the transformer was smaller than the transformer's BIL, which was 67.192kV<125 kV. the installation of the arrester after Fuse Cut Out is better because the voltage hitting the transformer is smaller than the installation of the arrester before Fuse Cut Out with a voltage difference of 69,092 kV - 67,192 kV = 1.9 kV.

Tripping Coil has a major effect on 150kV power termination equipment which must be ready to cut off the electrical circuit in the event of a disturbance. Analysis of the working ability of Tripping Coil on the 150kV Bay Capacitor power breaker at the Kotabumi Substation, aims to determine the cause of the decrease in the working ability of Tripping Coil and extend the Life Time of Tripping Coil. The final measurement results obtained the value of Tripping Coil resistance 1 phasa R 26.5Ω with Vnom (nominal voltage) calculated is 74.2 Vdc and Tripping Coil resistance 1 phasa T 26.1Ω with Vnom (nominal voltage) calculated is 74.2 Vdc which means it is still below the PLN standard (<77Vdc). From the analysis of research on Tripping Coil equipment, it is found that the tightness of the Tripping Coil terminals affects the measured value of coil resistance. Then the amount of voltage flowing into the coil affects the movement of the coil rod. The smaller the voltage flowing on the coil, the weaker the rod coil moves. However, the greater the voltage flowing on the coil, the faster and stronger the rod coil will move (but adversely affect the coil). And maintenance by checking the condition of the terminals and testing the coil can maintain reliability and extend the life of the Tripping Coil.

Authors: - Neha Sajwan , - Rajesh Kumar Sharma , - Dinesh Chandra
Published: February 2023

The name Ayurveda means "Knowledge of Life" Alternative medicine used from ancient times in the Indian subcontinent is known as ayurveda. The roots of our body are Dosa, Dhatu, and Mala. They are known as Dhatu because they maintain our body's homeostasis and keep it functioning normally. They are referred to as Dosa when there is an imbalance (increase or reduction). The biological forces known as doshas operate through the use of malas and dhatus. The structural elements are the dhatus and malas, and the energy forms are the Doshas. To reach the intended organ throughout the body, the Vata must pass via the Vata Vaha Srotas. These channels are split into two categories based on whether they serve motor or sensory purposes. Every Ayurvedic idea is predicated on and defined in terms of the Panchmahabhutas; the Doshas stand in for the Panchmahabhutas' physical presence in our bodies. And everything in the universe is Panchmahabhautika. One of the three basic Humours, Vata, has a significant impact on both health and sickness. The majority of the Vata disorders mentioned in Ayurveda are classified by current science as neurological ailments. We must thus comprehend the physiological concept of Vata in this study with particular reference to the neurological system.

Published: February 2023

Sri Lanka’s economy was already showing signs of weakness before the COVID-19 pandemic. Growth and poverty reduction had slowed down in the last five years. A restrictive trade regime, weak investment climate, episodes of loose monetary policy and an administered exchange rate had contributed to external imbalances. Sustained fiscal disparities, driven primarily by low revenue collections, combined with tax cuts in 2019, has contributed to high fiscal deficits, large gross financing needs, and a rapid growth in unsustainable debt .
The Sri Lankan economic crisis is an ongoing crisis in the island country of Sri Lanka that started in 2019. It is the country's worst economic crisis since its independence in 1948. It has led to unprecedented levels of inflation, near-depletion of foreign exchange reserves, shortages of medical supplies, and an increase in prices of basic commodities

Published: February 2023

Anxiety and insomnia are two of the most prevalent mental health conditions and a significant contributor to disability worldwide. We all experience feelings of anxiety, fear, and worry at many point in our lives. These feelings can have a negative impact on every individual’s mental and physical health if they persist for an extended period of time. Clinical anxiety disorders result from this. Anxiety disorders can be treated with a variety of methods and can also be treated with herbal remedies, as this article outlines.

In most countries, the lifetime prevalence of panic attacks—a type of anxiety disorder—is between 7-9 percent, and it is only 1% in India. On the other hand, the lifetime prevalence of generalized anxiety disorder is extremely high—it is 8.5% in the general population— according to WHO (2001). 16.6% of people worldwide suffer from anxiety disorders (Somers et al., 2006), and numerous efforts have been made to comprehend the disease's pathophysiology and treatment options.

Psychiatric disorders like depression, anxiety, and insomnia are very common and often co-exist with one another. Numerous individuals from all over the world have been affected by these well-known mental health conditions.

For the treatment of mental illnesses, herbal formulas and individual herbs are frequently prescribed. The use of herbs to improve health is on the rise as a result of the numerous side effects of western medicine. The study of herbal psychopharmacology has received a lot of attention in recent decades. The literature demonstrated a variety of herbal mechanisms of action, including re-uptake of monoamines, alteration of neuroreceptor binding and channel transporter activity, modulation of neuronal communication, and activation of the hypothalamic-pituitary adrenal axis (HPA).

Global health discussions are focusing a lot on traditional herbal remedies. The use of medicinal plants has been the subject of some of the most research in Asia, and a number of Indian regions retain their rural traditions. The purpose of this overview is to highlight the use of wild and cultivated plants in India, specifically as sedatives and for treating insomnia, as well as to collect, analyze, and summarize the pharmacological activity of these plants, as well as clinical and pre-clinical studies on the most cited plants.

One key aspect of green computing is reducing greenhouse gas (GHG) emissions, which are gases that trap heat in the earth's atmosphere and contribute to global warming and climate change. COVID-19 has introduced significant challenges to the energy industry. Potentially new practices and social forms developed during the pandemic have created an impact on energy demand and consumption. As there is an adverse effect on the global environment, it is time to improve the working habits of computer and business users. The aim of this study is to show the increased household energy consumption during the COVID-19 pandemic due to the rapid rise in the purchase and usage of electronic gadgets in Indian households. Due to the widespread adoption of the "work from home" mentality by businesses even after the epidemic, it has been noted that this has persisted. The study utilized the non-experimental quantitative research design specifically, the survey method which employs a descriptive questionnaire to the respondents. Information was gathered through a survey of 101 families in the Indian state of Maharashtra's three districts, Mumbai, Thane, and Palghar. A supervised machine learning model called regression analysis is used to verify the predictions. Investigation reveals that energy consumption is not only dependent on age, area, number of people, and number of gadgets owned by people but on various other factors.
Examining accuracy-prompt efficacy in combination with using colored borders to differentiate news and social content online
Authors: Bhardwaj Venya , Martel Cameron , Rand David G.
Published: February 2023

Recent evidence suggests that prompting users to consider the accuracy of online posts increases the quality of news they share on social media. Here we examine how accuracy prompts affect user behavior in a more realistic context, and whether their effect can be enhanced by using colored borders to differentiate news from social content. Our results show that accuracy prompts increase news-sharing quality without affecting sharing of social (non-news) posts or “liking” behavior. We also find that adding colored borders around news posts increased overall engagement with news regardless of veracity, and decreased engagement with social posts.
THE INFLUENCE OF MINERAL AND MICROFERTILIZERS ON THE HEIGHT OF SPRING BARLEY PLANTS IN THE CONDITIONS OF THE RIGHT BANK FOREST STEPPE OF UKRAINE
Authors: Polishchuk Mihaylo , Tynko Valentyna
Published: February 2023

Ukraine is a powerful participant in the world grain market, and grain stocks of domestic farmers are an integral part of global food security. Among cereals in the agro-industrial production of barley is a leading place in the structure of sown areas, it is second only to wheat. However, when conducting a comparative analysis of the yield of barley in Ukraine and other world producers, it should be noted that the average yield of its grain in our country is 2.5 t / ha, while in France it reaches 6.09 t / ha, Great Britain - 5 , 67, Germany - 5.69 t / ha [2]. Therefore, there is a need to find ways to increase the productivity of spring barley in specific conditions of its cultivation. One of the main ways to increase crop productivity is the stable growth and development of spring barley. Development is the formation of specialized organs and parts of aplant to perform its main biological function: the preservation of its species. Of particular importance in the cultivation of cereals are the processes of growth and development that underlie the formation of grains. One of the most important problems of plant growth and development in the technology of growing crops, in particular spring barley, is its growth processes. A characteristic indicator of growth processes, which affects the formation of crop yields, is its height. During our research, a lot of attention was paid to the development of culture in the right-bank forest-steppe of Ukraine.As a result, it was found that the height of plants increased from the germination phase to full maturity, due to increased plant biomass and depended on varietal characteristics and technological methods of cultivation and hydrothermal regime of years of research. Higher plant height in the phase of full maturity was observed in the variety Aizhan - 55 cm, and in the variety Aristei - 50 cm. It was found that depending on the factors studied, the height of spring barley plants in the tillering phase did not change significantly, but starting from the exit phase into the tube, the difference in height was significant. The application of mineral fertilizers provided an increase in the height of spring barley plants.

Authors: Didur Igor , Shevchuk Victoria
Published: February 2023

The article describes the results of research on the content and ratio of photosynthetic pigments in the stipules of winter peas using different cultivation technologies. The objects of the study were winter pea plants (Pisum sativum L.) of variety NS Moroz, plant growth regulator (PGR) Endofit L1 RK, bacterial preparation Bioinoculant BTU-r, microfertilizers «LF-Bobovi» and Biobor 140. The purpose of our research was to study the formation of photosynthetic pigments of winter pea plants under the action of growth regulator Endophyte L1 RK, bacterial preparation Bioinoculant BTU-r, their complex applying and foliar treatment systems with microfertilizers «LF- Bobovi» and Biobor 140. Analysis of chlorophyll and carotenoid content in alcohol extract (96.0%) was performed using a spectrophotometer Ulab − 102UV (China) at different values of wavelength: λ = 441; λ = 649; λ = 665. The volume of the working solution was 25 ml. Calculations of these indexes were performed according to the formulas of H. K. Lichtenthaler. During the study period, the influence of plant growth regulator, bacterial preparation, and foliar fertilization on the content of chlorophyll a and b, their sum, and concentration of carotenoids in the stipules of winter pea plants were evaluated. The research results indicate the dependence of these indicators on the use of the growth regulator and the bacterial drug, as well as on foliar fertilization. It was found that the implementation of foliar treatment in the phase of 3-5 stipules and complex use (in phases 3-5 of stipules and buttons) phase with tank mixtures of micro fertilizers «LF- Bobovi» (1.5 l / ha and 2.5 l / ha) and Biobor 140 (1.0 l / ha) led to an increase of the content of chlorophyll a and b, their total amount and carotenoid content. The highest content of chlorophylls a and b, their sum, and carotenoids in the stipules of winter pea plants were in the variant with the combined use of pre-sowing seed treatment with growth regulator Endophyte L1 RK (0.01 l / t), bacterial preparation Bioinoculant BTU-r (2 l / t) and at foliar treatment with microfertilizers «LF- Bobovi» (1.5 l / ha and 2.5 l / ha) and Biobor 140 (1.0 l / ha).The search for ways and opportunities to increase the grain yield of winter pea varieties Moroz due to the introduction of new technological methods of its cultivation remains relevant. A possible solution to the problem of improving the productivity of winter peas is the use of different mechanisms of action of plant growth regulators, inoculation with symbiotic microorganisms, and foliar feeding with tank mixtures of chelated microfertilizers.

There is a direct dependence of crop growth and its formation on the optimal combination of weather and climatic conditions and nutrients of crops. The soil cover of the experimental field is represented by chernozem southern low-humus dusty-heavy loam on brownish-pile forest-like loams. According to the content of mobile elements, the soil is characterized by an average content of nitrogen and phosphorus and a very high content of potassium. In the field experiment, sunflower cultivation techniques were generally accepted for the area, except for the variants studied according to the experimental scheme. In the variants where microfertilizers were studied, foliar feeding of sunflower hybrid plants was performed according to the experimental scheme. In a two-factor field experiment during 2020-2021, the yield and seed quality of high-oleic sunflower hybrids depending on the timing of microfertilizers were studied. The studied sunflower hybrids are included in the State Register of Plant Varieties of Ukraine and are recommended for cultivation in the Steppe zone. The results of the study showed that foliar fertilization with microfertilizers affects the performance of individual productivity, in particular when applying Quantum in the phase of 6-8 leaves on crops of sunflower hybrid NK Kamen husk was 21.1%, which is less than the control (without microfertilizers) by 0, 8%, and the weight of 1000 seeds was 2.6% larger, and accordingly the diameter of the basket increased by 1.2 cm. The effect of microfertilizers on the yield of the studied hybrids was also different: on average over the years the highest yield was formed by applying the drug Quantum in the phase of 6-8 leaves, and was: in the hybrid Darius 2.26 t / ha, in the hybrid NK Kamen − 2.55 t / ha and in the hybrid Tutti − 2.41 t / ha; Foliar fertilization significantly affected the quality of fat, in particular, the highest oil yield was obtained by applying Quantum in the phase of 6-8 leaves in the hybrid NK Kamen – at 13.4 kg / ha, which is more than the control (without microfertilizers) by 2.2 kg / ha, and the smallest − for the use of Rostock in the phase of 6-8 leaves, in the hybrid Darius, which amounted to 10.5 h / ha, which is more than the control of 1.2 h / ha. According to the research results, it is recommended to to carry out sowing in field crop rotations as the best option for NK Kamen sunflower hybrid under the condition of foliar top-dressing with Kvantum microfertilizer with a working fluid consumption rate of 4 l/ha in the culture phase of 6-8 leaves.

The article presents the results of research to determine the optimal technological methods of growing seed potatoes. The optimal nutrition background and method of fertilizer application, weight of planting tubers and potato varieties have been established, which provide high indicators of economic and energy efficiency of these elements of potato growing technology. The highest indicators of economic efficiency of potato growing were noted in the experimental version, where against the background of phosphorus-potassium fertilizer and the action of semi-roasted manure was carried out local application of Nitroammophoska (N45P45K45). The highest conditional net profit was 228,300 and 184,900 UAH / ha in the varieties Granada and Memphis for fraction of seed tubers 28-60 mm. However, the highest profitability was observed against this background of nutrition and method of application, but for fraction of seed tubers < 28 mm in varieties of Granada - 216.6; Memphis - 178.1 and Laperla - 153.1%, and fraction of seed tubers 28-60 mm - 157.6; 126.9 and 102.4%, respectively, in these varieties of potatoes. The decrease in the level of profitability was observed for fraction of seed tubers ˃ 60 mm to 99.9; 78.6 and 59.1%, respectively. This is due to the significant costs of planting material from 5.4 to 5.5 t / ha and the increase in the cost of planting material, and despite the increase in yields has led to lower profitability. Option, where against the background of phosphorus-potassium fertilizer and the action of semi-fermented manure was carried out local application of Nitroammophoska (N45P45K45) provided the highest energy efficiency. Thus, the energy yield with a yield ranged from 109.89 to 141.71 and from 120.25 to 152.07 GJ / ha with an increase in the fraction of seed tubers and different varietal composition. The highest coefficient of energy efficiency was observed for fraction of seed tubers < 28 mm, which varied from 1.78 to 2.28 and was less than the maximum for fraction of seed tubers ˃ 60 mm - 1.62-2.04.

Maize is a crop with a high yield potential and depends on technologies adapted to the conditions of the region. To form a high yield, the crop needs a balanced diet. One of the most effective means of influencing the yield and quality of corn grain is the application of mineral fertilizers. Foliar fertilization of corn crops can be an effective agronomic measure to stimulatephysiological processes under the influence of growth regulators on the development of corn in the initial stages, providing plants with trace elements during the growing season. Studies have shown that the growth of the leaf surface of plants of maize hybrids increased significantly with the growth and development of plants and reached maximum values before the flowering phase, followed by a slight decrease in the area of the leaf apparatus in subsequent growing seasons. The highest indicators of leaf surface area were observed in the areas where growth stimulant Regoplant and microfertilizer Chelatin Zinc were applied foliarly in the phase of 3-5 leaves of corn. Thus, the leaf area of the middle-early hybrid of maize DKS 3795 was 0,429 m2/plant, which is more than in the control plots by 0,026 m2/plant. Accordingly, the leaf area of the medium-ripe hybrid DKS-3511 was at the level of 0,467 m2/per plant, which is greater than the control plots by 0,035 m2/per plant. One of the ways to increase the efficiency of energy use in the production of crop products is to optimize technological methods and increase the yield per unit area. Energy analysis, which is a concentrated expression of the law of conservation and conversion of energy, allows you to compare energy consumption and energy content (receipt) in the harvest. Energy costs for growing maize hybrid 3511 for grain in control areas (without treatment with drugs) increased to 58,75 GJ, with the introduction of microfertilizers and growth regulators to 70,52 – 75,31 GJ. The energy coefficient was highest in the areas where plant growth stimulant Regoplant and microfertilizer Chelatin Zinc were applied – 1,94.

The article presents and substantiates the peculiarities of spring wheat cultivation depending on the genotype, type of predecessor and different fertilizer rates. The varietal comparison of agrocenoses of foreign selection was made. The signs of influence of separate elements of technology on the field similarity of plants, their value of productive tillering and yield changes of spring wheat varieties. The share of influence of factors and their interaction on formation of spring wheat grain yield was determined. The research found that the field germination of spring wheat seeds after soybean, sunflower and corn varied depending on the year of research. For the cultivar Aquilon, the greatest variation in percent similarity was found between 2019 and 2020, ranging from 2.6% after soybeans to 5.0% after sunflowers. For the Collada variety, this difference was less and was 1.6% and 1.9% after soybean and sunflower, respectively. Therefore, the Collada variety was more plastic in relation to the predecessor. The highest coefficient of productive tillering of spring wheat plants in the variety Aquilon 1,90-1,93 was obtained with the fertilizer N120Р60К60. For the variety Shiroko productive tillering rate increased by 4-9% when N60Р60К60 was applied. When N120Р60К60 was applied, this figure rose by 7-12% and was 1.85-1.92. For the variety Kollada coefficient of productive tillering 1.85 was the highest after corn on grain and the application of mineral fertilizers in the rate of N120Р60К60. On average for two years of research grain yield of spring wheat variety Shiroko varied in the range of 4.38-6.38 t/ha, in the variety Aquilon - 4.02-6.07 t/ha, and in the variety Kollada - 5.36- 6.61 t/ha depending on the variants of experience. The share of the influence of the factors fertilizer, variety, forecrop was 55%, 18% and 9%, respectively. Between the interaction of factors the combination fertilizer-variety - was the highest and amounted to 2,3%.
