ELECTROSMELTING CONTROL IN ARC FURNACE AND LADLE FURNACE WITH CONTINUOUS SUPPLY OF IRON RAW MATERIALS INTO THE WELD POOL
Authors: Kharlamov Denis
Published: March 2023

The paper presents energy and technological indicators and designs of improved electric furnace units for melting steel from iron ore raw materials (IOR). A method of controlling an arc furnace with a continuous IOR supply is proposed, which gives the opportunity to control and regulate the active power of the furnace, thermal processes in the welding bath of the electric arc, as well as in the unit as a whole. The design of a ladle unit for out-of-furnace melt treatment is presented, which allows the melting of high-quality electrical steel and simultaneous treatment with inert gases. At the same time, it is possible to reduce the metal carbon monoxide and IOR melting time.

The purpose of this study is to analyze how using group work techniques has increased student learning activity. Class action research is the approach employed in this study. Planning, carrying out, observing, and reflecting are the four stages of this process. This study was carried out between March and May with participants in classes V. The study was done over the course of two cycles, with two meetings per cycle. The findings indicated that student learning activity increased with each cycle. This is demonstrated by the results of the students that participated in cycle I, where five students achieved a percentage of 15.62% and an average student learning activity of 62.19%. As opposed to cycle II, where 28 (twenty eight) students were active, the average student learning activity was 88.92% and the percentage of active students was 87.50%. In light of the average percentage of active students meeting the desired action intervention results, i.e. 80%, it can be stated that the implementation of the group work approach can boost the activeness of student learning. Increased student learning activity was accompanied by successful learning outcomes, namely 83.

Published: March 2023

Terboyo Semarang Terminal is getting worse day by day due to tidal water that always inundates the terminal Terboyo Semarang. The existence of the terminal is needed by the community, so the government as a public servant continues to do various ways to make the terminal users feel comfortable.  With the condition of the Terboyo terminal which is already less suitable for use as a passenger terminal, the Semarang City Government moved the Main Terminal located west of Semarang City, namely on Jl. Mangkang Raya Semarang in early 2016 with more complete facilities. With the passage of time, the Mangkang Terminal that has been provided by the government is not maximally used by traders, bus crews and passengers. In this study, the data from the research results were analyzed with qualitative methods by conducting direct observation or observation, interviews and documentation. from the results of interviews conducted by researchers, namely the bus crew and traders with the move of the terminal, the income received has decreased, which for the bus crew costs higher for diesel fuel and less time to rest. The use of this qualitative research aims to be more in-depth in understanding how much influence the terminal move has on traders, bus crews and passengers. The results of this research show an adverse impact, namely reduced income for bus crews, traders or sellers at the Terboyo terminal, while the impact on passengers is different, some feel benefited and some feel disadvantaged.

Traces of past bog burning culture in rewetted bog soils (Emsland region, Germany)
Authors: Nachtigall Solveig , Stockenhofen Thomas , Giani Luise
Published: March 2023

Until the beginning of the 20th century, bog burning culture was a common cultivation system for food production on otherwise non-arable bog peat soils. Burning and preliminary drainage of the peat impacted the soils nutrient supply, bog morphology and soils properties. To gain insights into the long-term effects of bog burning culture on the landscape and soils, a burned and unburned area within a rewetted bog complex were comparatively analysed. It was hypothesised that bog burning had a lasting effect on the soil chemistry, that the trenches created for drainage prior to burning are still detectable in the bog morphology, and that the altered soil chemistry exhibiting enhanced nutrient supply resulted in a change of vegetation patterns. To verify this, the soil chemistry was analysed regarding pH, carbon/nitrogen (C/N) ratio, and contents of plant available phosphate (PO43-) and potassium (K). The morphology was examined by means of aerial imagery and vegetation patterns were assessed in the field. It was shown that while PO43-- contents were similar, pH values and K contents of the burned area were elevated compared with the unburned area. Accordingly, they can be used as an indicator for bog burning culture, even a century after the end of the practice. As expected, C/N ratios were narrowed in the burned area, which however cannot exclusively be attributed to bog burning, since peat mineralisation in the previously drained bog soils caused narrowing C/N ratios as well. The trench structure for drainage was still visible in aerial images and vegetation patterns were similar in the burned and unburned areas. Overall, the aftermath of bog burning was still apparent in morphology and soil chemistry, however the effect was less severe than expected, as vegetation patterns and the overall restoration success were not impacted. This provides a reasonable expectation that bogs are resilient towards bog burning and the latter is no obstacle for successful restoration.

Filozofski aspekti novovjekovnog odnosa čovjeka prema Bogu
Authors: Greguric Ivana
Published: March 2023

U radu se promišlja novovjekovni odnos čovjeka prema Bogu, prirodi i znanosti uz pomoć nekih značajnijih mislilaca toga vremena. Stvaranje novovjekovne slike svijeta započinje samopostavljanjem čovjeka u samosvjestan subjekt koji postaje reprezentant svih bića u smislu njihove predmetnosti – čovjek kao mjera svih stvari – i ujedno središnje i najvažnije biće Univerzuma. Čovjek to postiže stvaranjem novih vrijednosti, koje ne stoje nasuprot starih vrijednosti, već nove vrijednosti utemeljuje na novom bitku, bilo da je riječ o tvrdnji – »znanje je moć« (Bacon); akciji samosvjesnog subjekta – »mislim dakle jesam« (Descartes); »volji za moć u vječnom vraćanju istoga« (Nietzsche); apsolutnom duhu »svjetske povijesti« (Hegel); oslobođenom radu kao »znanstvenom radu« (Marx) i, naposljetku, o znanstveno-tehničkom umu. U tom samopostavljanju novovjekovni subjekt lišava prirodu svakog dostojanstva i teleologije čineći je isključivo predmetom eksploatacije, a postavljanjem ovozemaljskog života kao sredstva za ostvarenje najviših vrijednosti »volje za moć« negira postojanje biblijskog Boga i sam želi postati »Bog« na zemlji uz pomoć znanosti koja dopire do prvih uzroka prirodnih pojava i mogućnosti stvaranja umjetnih bića bez Božje mudrosti. Današnje znanstveno-kibernetičko doba pokazuje da novovjekovni subjektivizam završava u »volji za moć« znanstveno-tehničkog uma koji društvo, prirodu i prirodu u čovjeku objektivizira čineći ih sredstvima svoga samosvršnog samorazvoja.
Am I winning or losing? Probing the appraisal of partial wins via response vigor
Authors: Chen Zhang , Eben Charlotte , Reimer Christina , Verbruggen Frederick
Published: March 2023

Attempts to obtain rewards are not always successful. Despite investing much time, effort, or money, sometimes individuals may not obtain any reward. Other times they may obtain some reward, but the obtained reward may be smaller than their initial investment, such as partial wins in gambling. It remains unclear how such ambiguous outcomes are appraised. To address this question, we systematically varied the payoffs for different outcomes in a computerized scratch card task across three experiments. To test outcome appraisal, we used response vigor as a novel proxy. In the scratch card task, participants turned three cards one by one. Depending on the turned cards, they either received an amount that was higher than the wager (win), an amount lower than the wager (partial win), or nothing (loss). Overall, participants responded to partial wins more slowly than losses, but more quickly than wins. Partial wins were therefore appraised to be better than losses, but worse than wins. Importantly, further analyses showed that outcome appraisal was not based on the net win or loss amount. Instead, participants primarily used the configuration of turned cards as a cue for the relative rank of an outcome within a specific game. Outcome appraisals thus utilize simple heuristic rules, rely on salient information (such as outcome-related cues in gambling), and are specific to a local context. Together, these factors may contribute to the misperception of partial wins as real wins in gambling. Future work may examine how outcome appraisal may be modulated by the salience of certain information, and investigate the appraisal process in contexts beyond gambling.
Differential expression of TMEM236 in colorectal cancer.
Authors: Mamoor Shahan
Published: March 2023

Cancer is a leading cause of death and colorectal cancer is among the most lethal cancers (1, 2). We mined published microarray datasets (3, 4) to determine in an unbiased fashion and at the level of the transcriptome genes most differentially expressed in the primary tumors of patients with colorectal cancer (CRC). We found significant differential expression of the gene encoding transmembrane protein 236, TMEM236, when comparing colorectal tumors to the tissue of origin, the colon. TMEM236 mRNA was present at significantly lower quantities in tumors of the colon as compared to normal colorectal tissue. Analysis of human survival data revealed that expression of TMEM236 in rectal tumors was correlated with overall survival in patients with rectal cancer. TMEM236 expression changes may be important for the initiation or progression of human CRC.
Surgery for Cancer: Types and Recovery

Published: March 2023

Surgery is a common treatment option for cancer and is often used to remove tumors and preventthe spread of cancer cells to other parts of the body. There are several types of cancer surgery,each with its own purpose and recovery process. Types of Cancer Surgery: Diagnostic surgery:This type of surgery is used to diagnose cancer by removing a tissue sample for examination.Diagnostic surgery is often performed using a biopsy, which can be done using a needle or byremoving a small piece of tissue during a minor surgical procedure. Curative surgery: Curativesurgery is performed with the goal of removing all cancer cells from the body. This type of surgeryis often used for early-stage cancers that have not spread to other parts of the body. Palliativesurgery: Palliative surgery is used to relieve symptoms caused by cancer, such as pain or difficultybreathing. The goal of palliative surgery is not to cure cancer, but to improve a patient's qualityof life. Reconstructive surgery

Pattern of private tutorship in Bangladesh: Factors affecting income distribution of students of Pabna University of Science and Technology
Authors: Hosen Miraz
Published: March 2023

Private tutoring has become a popular option for many university students in Bangladesh, especially in urban areas. Students at Pabna University of Science and Technology (PUST) are no exception, with many turning to private tutoring as a way to earn extra money, support themselves financially, and meet the expectations of their families. This study explores the real picture of private tutorship among students at PUST. Through a combination of online and offline questionnaire surveys, using purposive sampling, the paper identifies the factors that affect the income distribution of both male and female students. These factors include gender, Higher Secondary Certificate (HSC) background, and place of residence, dependency, patriarchy, and social perception. The study finds a significant variation in income distribution between the males and their counterparts at PUST. The study revealed several factors, such as higher secondary background, mobility, residence level, dependency, and solvency of family, that caused the variation in income from tutorship. However, few respondents think that tutorship has had a negative impact on their academic performance, while some do not know whether it has influenced their grades positively or negatively. The research contributes to the knowledge regarding the scenario of private tutorship among the public university students in Bangladesh, who mostly come from rural regions. This paper would be beneficial to different stakeholders, such as the government, university authorities, students, guardians, and academics who are related to the education system of Bangladesh.

Paleoenvironmental implications of Deccan volcanism relative to the Cretaceous-Paleogene mass extinction: evidence from the ‘red bole’ record
Authors: Sharma Nikhil , Adatte Thierry , Vennemann Torsten , Schoene Blair , Keller Gerta , Khadri Syed
Published: March 2023

Large Igneous Provinces (LIPs) have been widely studied over the past decades due to their likely link to mass extinction events. Previous work involving U-Pb zircon dating of the Deccan lava flows indicates that the main phase-2 began 250 Ka before the Cretaceous-Paleogene (K-Pg) mass extinction boundary and continued into the early Danian, suggesting a cause-and-effect relationship. Closer to the eruption centre, intra-volcanic red weathered horizons known as red boles mark quiescent periods between basalt flows. Red boles have increasingly attracted the attention of researchers to understand the prevailing climatic conditions during the Deccan volcanic activity for their ability to yield crucial evidence of environmental changes triggered by volcanic activity using different geochemical proxies such as major elemental composition, bulk rock and clay mineralogy, weathering indices, paleo-precipitation estimates and stable isotope analysis. Our results indicate that red boles are characterized by concentrations of immobile elements such as Al and Fe3+ ions that are typical of paleo-laterites, which develop over short periods of weathering. Identified clay minerals consist mostly of smectite indicative of semi-arid monsoonal conditions. Weathering indices suggest intense weathering most likely linked to increasing acid rains while stable H- and O-isotope compositions suggest increasing paleoclimate instability in parallel to increased eruption rates just before the K-Pg boundary. The multi proxy approach is compatible with a cause-and-effect relationship between the Deccan Trap eruptions and the K-Pg mass extinction.
Vulnerability of Firn to Hydrofracture: Poromechanics Modeling
Authors: Meng Yue , Culberg Riley , Lai Ching-Yao
Published: March 2023

On the Greenland Ice Sheet, hydrofracture connects the supraglacial and subglacial hydrologicsystems, coupling surface runoff dynamics and ice velocity. Over the last two decades, the growthof low-permeability ice slabs in the firn above the equilibrium line has expanded Greenland’s runoffzone, but the vulnerability of these regions to hydrofracture is still poorly understood. Observationsfrom Northwest Greenland suggest that when meltwater drains through crevasses in ice slabs, itis stored in the underlying relict firn layer and does not reach the ice sheet bed. Here, we useporomechanics to investigate whether water-filled crevasses in ice slabs can propagate verticallythrough a firn layer. Based on numerical simulations, we develop an analytical estimate of the waterinjection-induced effective stress in the firn given the water level in the crevasse, ice slab thickness,and firn properties. We find that the firn layer reduces the system’s vulnerability to hydrofracturebecause much of the hydrostatic stress is accommodated by a change in pore pressure, rather thanbeing transmitted to the solid skeleton. This result suggests that surface-to-bed hydrofracture willnot occur in ice slab regions until all pore space proximal to the initial flaw has been filled with solidice.
Efficient modeling of wave generation and propagation in a semi-enclosed estuary
Authors: Crosby Sean , Nederhoff Kees , VanArendonk Nathan , Grossman Eric
Published: March 2023

Accurate, and high-resolution wave statistics are critical for regional hazard mapping and planning. However, long-term simulations at high spatial resolution are often computationally prohibitive. Here, multiple rapid frameworks including fetch-limited, look-up-table (LUT), and linear propagation are combined and tested in a large estuary exposed to both remotely (swell) and locally generated waves. Predictions are compared with observations and a traditional SWAN implementation coupled to a regional hydrodynamic model. Fetch-limited and LUT approaches both perform well where local winds dominate with errors about 10-20% larger than traditional SWAN predictions. Combinations of these rapid approaches with linear propagation methods where remotely generated energy is present also perform well with errors 0-20% larger than traditional SWAN predictions. Model-model comparisons exhibit lower variance than comparisons to observations suggesting that, while model implementation impacts prediction skill, model boundary conditions (winds, offshore waves) may be a dominant source of error. Overall results suggest that with a relatively small loss in prediction accuracy, simulations computation cost can be significantly reduced (by 2-4 orders of magnitude) allowing for high resolution and long-term predictions to adequately define regional wave statistics.
Student Motivations, Perceptions and Opinions of Participating in Student Evaluation of Teaching Surveys: A Scoping Review
Authors: Sullivan Daniel M. , Lakeman Richard , Massey Deb , nasrawi dima , Tower Marion , Lee Megan Frances
Published: March 2023

Several times each year the teaching performance of academics at higher education institutions are evaluated through anonymous, online Student Evaluation of Teaching (SET) surveys. Universities use SET surveys to inform decisions about staff promotion and tenure. But low student participation levels make the surveys impractical for this use. This scoping review aims to explore student motivations, perceptions, and opinions of SET survey completion. Five EBSCO® databases were searched using key words: “student evaluation of teaching” OR “student evaluation*” OR “student rating*” OR “student satisfaction” OR “teach* evaluation” OR “teach* effective*” OR “teach* performance OR “student feedback*” OR “student survey” AND “higher*education” OR university OR college OR tertiary. Thematic analysis of a meta-synthesis of qualitative findings derived from 21 papers identified five themes: (i) The value students’ place on SET, (ii) the knowledge that SET responses are acted upon to improve teaching, (iii) assurance of survey confidentiality and anonymity, (iv) incentives for completing SET, and (v) survey design and timing of survey release. Perceptions, knowledge, and attitudes about the value of SET are essential factors in motivating students to engage and complete SETs, particularly if surveys are easy to interpret, time for completion is incentivised, and responses are valued.
Remembrance of Things Past: Temporal Change in the Affective Signature of Nostalgic Events
Authors: Zengel Bettina , Wildschut Tim , Sedikides Constantine , skowronski john
Published: March 2023

Two experiments explored the affect and emotion changes over time (i.e., from event occurrence to event recall) that characterise nostalgic events, and how those changes differ from the affect and emotion changes that characterise ordinary (Experiment 1) and neutral (Experiment 2) events (control). Participants rated the affect and discrete emotions associated with events at the time those events occurred as well as when they were recalled. Nostalgic (but not control) events were characterised by a decrease in positive affect and an increase in negative affect over time. These temporal changes in global affect were mediated by parallel changes in certain discrete negative emotions associated with nostalgia (i.e., loneliness and regret), but not by changes in other discrete emotions (e.g., embarrassment, shame). Yet, nostalgic events were associated with more positive than negative affect, particularly at the time they occurred but also when recalled. Further, nostalgic events were associated with more positive affect than were control events, again particularly at occurrence but also at recall. This relative positivity of nostalgic (compared to control) events mediated the effects of recalling nostalgic events on psychological benefits. We discuss theoretical implications and offer suggestions for new research.
Police killings reduce trust: Predictors of trust in the police across 46 countries
Authors: Vilar Roosevelt , Hanel Paul H. P. , Coelho Gabriel Lins Holanda , Monteiro Renan P. , Liu James H
Published: March 2023

After police killings such as the one of George Floyd, trust in the police in the USA has plummeted. This is problematic because lower trust can lead to a range of disadvantageous outcomes for countries such as lower compliance with the law and difficulties for the police in recruiting qualified people from diverse backgrounds. However, it is unclear whether police killings are associated with lower trust beyond the USA. Across two studies (N = 48,889) including data from 46 countries, we predicted and found that police killings are negatively associated with trust in the police while controlling for a range of other variables. Additionally, we found that conspiracy beliefs are negatively associated with trust in the police whereas right-wing authoritarianism, system justification, socioeconomic status, and human development are positively associated with trust in the police. Together, our findings provide even more reasons why police killings should be reduced.

A key debate in language learning centers on how people successfully learn the extension of a novel word, despite inherent ambiguity in the input. Across two studies, we tested whether learners reduce ambiguity about a word’s extension by actively sampling the environment. Adult participants were first shown ambiguous learning situations in which novel words were presented with a set of exemplars that were drawn from a subordinate-level category (e.g., Dalmatians), a basic-level category (e.g., dogs), or a superordinate-level category (e.g., animals). Learners then had the opportunity to sample the label of additional exemplars. Participants systematically adapted their sampling choices as a function of training. Moreover, participants varied in their sampling strategies, pursuing both confirmatory strategies (selecting exemplars similar to the training set) and constraining strategies (selecting exemplars that constrain the word’s extension). Overall, these findings show that learners spontaneously pursue sampling strategies that support generalizing novel word meanings.

Published: March 2023

Large-scale surveys are of great importance in sociological research. However, the measurement quality of scales used in large-scale surveys is rarely investigated. To address this issue, the present study examined the psychometric properties and cross-national measurement invariance of the ISSP Occupational Commitment scale (ISSP-OCC) using the ISSP 2015 data. The ISSP-OCC scale is an ultra-short, two-item scale that has been administered in 38 countries. Our results indicate that the ISSP-OCC has acceptable psychometric properties in 31 countries; we found evidence of concurrent validity through correlations with other constructs such as organizational commitment and job satisfaction. Tests of measurement invariance indicated that metric invariance held in 31 countries and scalar invariance held in 22 countries. Although our results indicate that the ISSP-OCC is suitable for national and international surveys in many countries, they also highlight the importance of examining the measurement quality of scales used in large-scale surveys.

Coarse data, mediation analyses, models that include intermediate outcomes and other purported statistical refinements tend to “residualize” the effect of social and economic background out of existence. We provide a brief overview of how overcorrection occurs and suggest how it may be avoided.

A variety of plant species, especially woody plant species, can be micropropagated using the crucial technique of in vitro micrografting. In vitro micrografting has developed over the past few decades into a method to speed up shoot recovery and adaptation of horticultural species cultivated in vitro. This review analyses studies on horticultural crops that address the development of in vitro micrografting, factors influencing its performance, and the contribution of micrografting applications to the field of micropropagation. The potential application of this technique is based on the significant contributions that micrografting makes to the recovery of vigour and rooting competence, the promotion of shoot recovery following somatic embryogenesis and organogenesis, and the facilitation of shoot regrowth following cryopreservation. This technique facilitates the genetic engineering and preservation of horticultural crops are highlighted.
Economic Empowerment of Fisherfolk through Entrepreneurship
Authors: Noronha Sandra
Published: March 2023

Economic empowerment is the ability to make and act on decisions that involve the control over and allocation of financial resources (Golla et al., 2011).

Entrepreneurship is the ability to create and build something from practically nothing (Jaffrey.A.Timmons)

Entrepreneurship is generally considered as a means to economic empowerment of masses. It is also a solution to the two major problems faced by developing countries i.e unemployment and underemployment. Unemployment is a condition where people remain jobless without income for continuous period of time. Underemployment is a condition where people are forced to work in low paying or low skill jobs. Entrepreneurship can sufficiently tackle these two issues. It has a wider scope in the sense that it creates a lot of employment opportunities, provides flexibility and independence, opportunity to make a difference and an opportunity to contribute to the society. Taking into account the condition of marginalized people in Kerala, one of the major problems faced by them are financial constraints. When fisherfolk community is considered, their income is purely seasonal in nature. Off seasons can be overcome through logical exploration and application of entrepreneurial initiatives. This paper attempts to examine the ways in which entrepreneurship can be applied in the fisheries sector in Kerala.

The main indicator that determines the competitiveness of cherry fruits is the average weight of the fruit and the ratio of stone to pulp, so the study of cherry fruits of different cultivars according to these qualitative indicators is relevant. The popularity of cherries among consumers is due to the high taste qualities of fruits with an attractive appearance, as well as the early ripening period. The purpose of the research was to study the average fruit weight and stone weight of 33 cherry cultivars of three ripening periods, both introduced varieties and those included in the State Register of plant cultivars suitable for distribution in Ukraine, and to select varieties and variety samples that have scientific and practical value for studied parameters. The determination of the average weight of the fruit, the weight of the stone and their ratio of the stone to the pulp in cherry fruits was carried out in the period of consumer ripeness. Selection and preparation of samples for analysis was carried out according to DSTU ISO 874-2002. The average weight of the fruit in cherry fruits grown in the conditions of the Southern Steppe zone of Ukraine was 8.41 grams, the average stone weight was 0.56 grams. The fruits of the late ripening cherry group had the optimal fruit mass (7.27–12.18 g). The varieties ‘Svit Erliz’ and ‘Rubinova Rannia’ turned out to be the most stable with the minimum coefficients of variation according to the studied parameters in terms of the early maturing cultivars in terms of fruit weight and stone weight. Among the group of medium-ripening varieties, the most stable fruit and stone mass were the fruits of the cultivars ‘Temp’ and ‘Vinka’. In the group of cultivars with a late ripening period, the smallest variability of fruit mass and stone content was recorded in the cultivar ‘Regina’. It was established that the weather conditions of the research years had a dominant influence on the formation of fruit mass in all groups of cultivars. Varietal features had a dominant influence on the weight of the bone. The results of the research will be interesting for industrial and amateur horticulture in Ukraine

Relevance of the research is determined by the need to study the influence of the region’s hydrothermal resources on the alfalfa leaf-stem mass and seed yield formation, which is important in the present climate change conditions. In this regard, the article is aimed at identifying the influence of precipitation and temperature regime on the growth and development of plants of varieties and hybrids according to mowing cycles and years of grass stand use. In the research, the following methods were used: field (conducting phenological observations and records), laboratory (structural analysis of the grass stand), mathematical and statistical (objective evaluation of the experimental data obtained). It was found that the amount of precipitation from the beginning of the period of relative rest until the onset of active temperatures above 10˚C had the greatest influence on formation of the 1st mowing; the amount of precipitation after the establishment of active temperatures above 10˚С and up to the moment of the leaf-stem mass yield accounting had a moderate effect on the formation of the 2nd mowing and strong – on the 3rd one; the amount of precipitation of the previous mowing period – on the 2nd-4th one (the strongest – on the 4th); the sum of active temperatures above 10˚С – on the 1st and 3rd mowing; hydrothermal coefficient indicators – on the 2nd-3rd ones; duration of the growing season with active temperatures above 10˚С – on the 1st and 3rd. Seed yield, in contrast to feed productivity, largely depended on the amount of precipitation before the flowering phase and during the growing season of alfalfa in general. It was established that the yield of dry matter and seeds productivity are influenced by: the sum of active temperatures, the amount of precipitation per mowing or plant vegetation period, and the genetic characteristics of the hybrids and varieties under study. It was discovered that the hydrothermal conditions of the year differently influence the level of plant productivity – excessive and sufficient moisture increases feed productivity and reduces seed yield. The obtained data are of practical value for predicting the yield of the green mass of alfalfa in each subsequent mowing depending on the amount of precipitation during the previous growing season, as well as for the development of programs for the creation of synthetic varieties with the increased productivity rates of leaf-stem mass and seeds.
