Solid organic fertilization of soil proves one of the most important factors which contributes to increasing the yielding capacity of farm crops and improving their production qualities. Along with other means of mechanization body machines are used for the mechanized fertilization of soil through distributing fertilizers along the field surface. The paper is aimed at determining and investigating the carrying capacity of body machines used for applying solid organic fertilizers depending on their load-carrying capacity. The research technique lies in the comparative analysis of the determined resultative and factorial characters on the basis of the information obtained from the enterprises wlurh produce body machines. The information was chosen from the catologues of farm machinery and folders of the corresponding enterprises that produce tluse machines. The carrying capacity of machines was determined as the second-by-second advance of fertilizers in mass units (kilograms) to working parts of spreaders through the corresponding calculations; and the processing of harvesting and calculated data was carried out on the principles of the correlation and regression analysis, as wele as with the use of standard computer programs. The volume of statistical sampling amounted to 43 pairs of the investigated characters. The above has made it possible to estaflish. The positive correlation link between the carrying capacity of machines and their load-carrying capacity with the correlation coefficient amounting to 0.647 according to the correlation link of the resultative character on the factorial one, which equals 0.671. To ultimately determine the character of the relation between the investigated characters the authors accomplished the beveling of statistical data related to the carrying capacity of machines depending on their load-carrying capacity in the form of equations with straight line with positive angular coefficient and a number of curved lincar dependences. With iespeet to R2-coefficient the best correlation with experimental data was achieved through their approximation by means of equations of slow increasing step function. Of the investigated change is presented by the equation of the increasing hyperbola (R2=0.820), then according to the hyperbola asymptote with the load-carrying capacity increase of more than 20 tons their carrying capacity can amount to the marginal value of 25 kg/ses. The investigated dependences have to be taken into account when designing body machines used for applying solid organic fertilizers, as well as when using them for soil fertilization under the technological processes of mechanized growing of farm crops.

Published: October 2021

El turismo representa una actividad fundamental dentro de una economía, por los diferentes impactos que tiene sobre otros sectores. En el mundo se está viviendo cierto auge en la actividad turística, reflejando Colombia similares tendencias en esta materia. Recientemente se está presentando un fenómeno revaluativo del tipo de cambio peso-dólar, aspecto este que motiva al estudio de tal situación, e indagar la influencia que tiene esta variable sobre la demanda de exportaciones y de importaciones turísticas, lo que constituye el objeto de estudio del presente trabajo. El método de MCO (Mínimos Cuadrados Ordinarios) es la herramienta que permite la consecución de tal propósito, luego de verificar la existencia de raíces unitarias. Finalmente los resultados obtenidos permiten concluir que para los turistas extranjeros los precios relativos no resultan ser determinantes al decidir considerar a Colombia como destino turístico y que los colombianos que deciden efectuar turismo en el exterior están aprovechando el contexto revaluativo favorable, que se refleja en las progresivas disminuciones en el nivel de precios internos.Palabras Clave: turismo, demanda, revaluación, precios relativos

Los temas que ocupan la atención de los medios terminan siendo los que ocupan nuestra atención, y no al revés como a veces creemos -y deseamos. Las investigaciones que estudian cómo los medios seleccionan los contenidos a los que dedican sus mensajes, qué es y qué no es noticia, reciben el nombre académico de agenda-setting, y pretenden dilucidar que es prioritario en la agenda de los medios masivos, como se construyen las noticias y como estas a su vez conforman una realidad mediática que termina diciéndonos que es lo realmente importante para nosotros.

Authors: Kareem Urdak Ibrahim , Hashim Fadhaa Mezher
Published: October 2021

A mixture model is used to model data that come from more than one component. In recent years, it became an effective tool in drawing inferences about the complex data that we might come across in real life. Moreover, it can represent a tremendous confirmatory tool in classification observations based on similarities amongst them. In this paper, several mixture regression-based methods were conducted under the assumption that the data come from a finite number of components. A comparison of these methods has been made according to their results in estimating component parameters. Also, observation membership has been inferred and assessed for these methods. The results showed that the flexible mixture model outperformed the others in most simulation scenarios according to the integrated mean square error and integrated classification error
Macro Sustainability Accounting: A New Way to Prepare Value Added Statement
Authors: Ali Mohammed Ataallah , Abdullah Salman Hussein
Published: October 2021

Traditional accounting takes only one dimension (economic) in calculating the value added of the company, and all other aspects (including environmental and social) are neglected, and despite the emergence of Sustainability Accounting and the interest of companies in preparing sustainability reports, these reports are suffering from many problems, including multiple metrics used in measuring companies (cash, quantity and lavish). In addition, these reports may reach dozens of pages in some companies and this causes the problem (information overload) which affects the qualitative properties of accounting information such as appropriate and relative, which requires the need to find a tool that can measure the Sustainability Unit of standard measurement, so easy to understand and use in comparison with standard reference (benchmark).

The problem of research is the neglect of the cost of non-sustainability borne by society and the planet as a result of companies exercising their activities inefficiently, where these costs do not appear in the records of the companies causing them because of the common saying (that what cannot be measured cannot be managed and therefore cannot be held accountable) and this encourages companies to neglect sustainability.

As a result, the research aims to find an objective way to measure the cost of non-sustainability incurred by society and the planet as a result of the inefficiency of these companies in the management of their activities, therefore, these costs can be charged to the companies that cause them, as this will play a significant role in changing the perception of corporate managers towards sustainability.

 

The research led to a set of results, including the palaces of accounting tools (all branches) in measuring the cost of non-sustainability in cash.

The research presented a set of recommendations, the most important of which is the need to take into account macro sustainability accounting by the stakeholders of this profession, and develop value-added statement using the technologies developed by the researcher (SVA$) because of its role in measuring the cost of non-sustainability critically, which will have a significant role in changing the corporate view for neglecting sustainability

Does neonatal brain ischemia induce schizophrenia-like behavior in young adult rats?
Authors: Tejkalová H , Kaiser M , Klaschka J , Šťastný F
Published: October 2021

Perinatal cerebral hypoxia represents a major cause of obstetric complications and the resulting transient oxygen deficiency might belong to early risk factors for schizophrenia. The aim of this study was to evaluate possible long-term behavioral changes induced by one hour of continuous bilateral common carotid artery occlusion in 12-day-old male rats. Post-ischemic behavioral disturbances were evaluated in social (play) behavior on postnatal day 22 (PND 22), open field test (PND 35 and 50) and prepulse inhibition of the acoustic startle reflex (PND 50). Transient ischemia in neonatal rats was not significantly altered in social dyadic interactions evaluated in pre-weaning pups, but resulted in enhanced locomotor activity in pubertal rats (PND 35) and impaired prepulse inhibition of the startle reflex in post-pubertal males (PND 50). These behavioral alterations suggest that perinatal hypoxic/ischemic insults may represent a risk factor for later manifestation of specific features relevant to schizophrenia in predisposed individuals.
Velocity of body lean evoked by leg muscle vibration potentiate the effects of vestibular stimulation on posture
Authors: Dzurková O , Hlavačka F
Published: October 2021

To investigate the vestibular and somatosensory interaction in human postural control, a galvanic vestibular stimulation of cosine bell shape resulting in a small forward or backward body lean was paired with three vibrations of both soleus muscles. The induced body lean was registered by the position of the center of foot pressure (CoP). During a quiet stance with eyes closed the vibration of both soleus muscles with frequency (of) 40 Hz, 60 Hz and 80 Hz resulted in the body lean backward with velocities related to the vibration frequencies. The vestibular galvanic stimulation with the head turned to the right caused forward or backward modification of CoP backward response to the soleus muscles vibration and peaked at 1.5-2 s following the onset of the vibration. The effect of the paired stimulation was larger than the summation of the vestibular stimulation during the quiet stance and a leg muscle vibration alone. The enhancement of the galvanic stimulation was related to the velocity of body lean induced by the leg muscle vibration. The galvanic vestibular stimulation during a faster body movement had larger effects than during a slow body lean or the quiet stance. The results suggest that velocity of a body postural movement or incoming proprioceptive signal from postural muscles potentiate the effects of simultaneous vestibular stimulations on posture.
CARBOHYDRATE COMPOSITION IN RELATION TO PASTURE QUALITY
Authors: Bailey R.W.
Published: October 2021

THE TERM "pasture quality" is a measure of the ability of the pasture to provide the nutritive requirements of the grazing animal. Many plant constituents contribute to this policy but only one group, the carbohydrates, will be considered here. At present probably the only reliable and meaningful method of assessing the relative nutritive value of different pastures is by comparing actual animal production on the pastures growing under identical conditions. Such a method is, of course, unsuitable for the plant breeder during the early stages of a plant breeding programme when he needs to select for quality from a large number of plant progenies. For this reason, it is desirable that quality be defined in more specific terms so that relatively simple tests for it can be devised. Work aimed at such a definition should, of course, be based on material from pastures whose animal potential is being measured at the same time. For this reason, work at Plant Chemistry Division on the possible role of the carbohydrate constituents in contributing to nutritive value has been based largely on material from single variety ryegrass pastures on which growth rate in sheep has been the index of animal production. The present account of how the plant carbohydrate composition of pasture can influence pasture quality will be illustrated with results obtained from these trials.

Published: October 2021

Scarcity of water is a major existing problem in India. Of all the water available to us, only 3% is pure and usable, and with more than 7 billion people on earth. Rainwater is the most undervalued of the types of freshwater available. Rainwater harvesting is one of the oldest and simplest method for saving and using water. It can be used for residential and household projects, and even larger systems for schools, hospitals and other facilities. Considering the scarcity of water in our country, lesser use of rain water and depleting renewable sources of energy, this model was developed to make it useful for masses and at a affordable price.

Introduction: Patients of FRCC ICMRR undergo rehabilitation after "cerebral accidents" of acute cerebrovascular accident (ACVA), Traumatic Brain Injury (TBI), brain surgery. During the pandemic COVID-19 (20202021), the hard situation of patients dealing with the disease is made more difficult by the visits ban in the hospital. Patients are forced to stay a month or more of loneliness, away from family and loved ones, in conditions of "isolation". Aims: Was to identify the frequency of occurrence and severity of anxiety and depressive disorders among patients caused by a long stay in the hospital, limited communication with relatives due to the COVID-19 pandemic. Materials and methods: The study group consisted of 132 patients of the Federal Research and Clinical Center of Intensive Care Medicine and Rehabilitation (FRCC ICMRR) who were hospitalized during the COVID-19 pandemic (from May 2020 to April 2021); the comparison group consisted of 104 patients who were treated in the FRCC ICMRR in 2019. After studying the medical documentation, 2 groups of patients were formed: the study group of 21 people and the comparison group of 24 people with an identical distribution by gender and age, by the severity of neurological deficit (mild and moderate severity of the lesion), localization of the process, criteria of social activity. The following methods were used in the study: organizational-comparative method; empirical-observation, conversation, questionnaire; psychodiagnostic methods-tests (ODS-2, HADS, STAI), the method of expert assessments, a qualitative method of data processing (differentiation of material by groups, its analysis). Results: The stress of hospitalisation and unvoluntary isolation makes patients mental health much worse, causes mental maladjustment, and often manifests itself in the development of anxiety-depressive pathopsychological symptoms: the frequency of occurrence of personal anxiety increased by 3 times; the severity of the symptoms of situational anxiety increased by 1.5 times, no cases of neurosis were detected among patients of both groups. Conclusions: To reduce the negative consequences of psycho-emotional stress from unvoluntary isolation, to prevent the formation of social-stress disorder, it is necessary to carry out a number of activities not only in a separate institution, but also at the global level.
QVD: Improving Quality – User Story as a Quality Value Driver (QVD) in Software Development
Authors: Davidian Moshe , Lurie Yotam , Mark Shlomo
Published: October 2021

The term "software quality" is widely used, and although it has many definitions, no one definition is universally accepted. Often, the definition refers to specific phases of the software development process and not to software as a whole. In our article, in order to improve the quality of the software, we decided to improve the quality of the phases. To do that, we will focus attention on the drivers that advance quality value and use a new concept called QVD - quality value drivers. We focused on the requirements phase of software development, which probably ranks as the crucial first step. Hence, as a QVD we present the idea of "User Story" (US), a short and simple description of a functionality valuable to a user of a system. In the study, a comparison is made between requirements written by the US method and requirements that are not. After analyzing the results, we concluded that requirements written by the US method have been better understood and evaluated as less difficult to develop. The overall quality rating of their writing is higher than previously. In addition, learning the US method gives the person the ability to better assess the quality of requirements. Finally, improving the writing of the requirements using the US method as QVD improves the quality of the development process, eventually improving the software quality.

One of the systems for oil and gas production supports is the nitrogen compression system. Problem found that condition of the compressor has high vibration with the maximum overall the first compressor is 9,813 mm / s RMS, the second compressor is 7,439 mm / s RMS, the third compressor is 7,430 mm / s RMS, the fourth compressor is 13.47 mm / s RMS, the fifth compressor is 13,220 mm / s RMS, and sixth compressor already damaged. This research will discuss the nitrogen compression process in terms of the characteristics of the output fluid flow from the compressor using computational fluid dynamics. The first piping system shows that the standby compressor's flow has a higher pressure reaching 10.72 - 11.82 Pa but it is still acceptable. The second piping system with two compressors in operation shows that the pipeline flows in the opposite direction with high pressure. Flow turbulence occurs, resulting in a higher speed. The highest pressure in the pipeline reaches 44.79 Pa, mostly at the fifth and sixth compressors. The conclusion from this research there is high pressure backflow when one compressor stops and another compressor start running. Prevents direct pressure to the compressor or the condensed fluid from the gas flowing and entering the compressor used valve addition.

Polymorphism examination was carried out by Sanger sequencing. RESULTS: VDR rs2228570 T/T and T/C-T/T were significantly associated with higher risk of active tuberculosis. VDR rs7975232 G/G genotype was associated with an increased risk of developing active TB compared to T/T-T/G. Haplotype analysis of VDR rs2228570, rs1544410, rs7975232, rs731236 and combination with MIF rs755622 demonstrated that TGGTG was observed to have a higher risk of tuberculosis. CONCLUSIONS: The combination of VDR and MIF variants may contribute to the susceptibility of active tuberculosis disease.
Identifying the Diversity of Self-Sown Native Coconuts (Cocos nucifera L.) and the Introduced Phenotype in Queensland, Australia
Authors: Leu André
Published: October 2021

The claims that all coconuts (Coco Nucifera L.) were introduced into Australia by Europeans were researched by studying the journals of the maritime expeditions, the records of the Queensland Acclimatisation Society, historical data and published papers. The 1869 minutes of the Queensland Acclimatisation Society stated that no introduced coconuts were fruiting, and the Queensland Governor stated that there were self-sown coconut palms on the coast. A large spherical niu vai phenotype was introduced from the 1870s to 1900. Field research was conducted in the vicinity of an historical coconut plantation at Wonga Beach. Nuts and palms were examined to understand if all coconuts in that region were descended from the introduced phenotype. Most self-sown coconuts are intermediate types with native Australian origins, not the introduced phenotype.

Background and objective: The last randomized controlled trials ,the ACOSOG Z6051 1,2 and the ALaCaRT trial3, 4 could not show the non-inferiority of the laparoscopy in comparison to laparotomy for rectal cancer. In fact, the ten first years of practicing laparoscopy were years when surgeons developed their learning curve. Therefore, by excluding this learning bias, it is possible to end up with a more fair and correct comparison between the two techniques. It is henceforth relevant to pursue a new meta-analysis that compares the two techniques and excludes studies done during the earlier periods of laparoscopic rectal surgery. Results: Six randomized controlled trials met the eligibility criteria, involving a total of 1556 patients in the laparoscopy group and 1188 patients in the laparotomy group. Our meta-analysis was in favor of laparoscopy in a significant way for blood loss, first bowel movement and the number of harvested lymph nodes. It was non-significantly in favour of laparoscopy for 30-days mortality after surgery and length of hospital stay. It was significantly in favor of laparotomy for operative duration. No significant difference was found in anastomotic leakage) , reoperation within 30 days, number of positive CRMs and completeness of mesorectal excision between the two groups. No difference was found in recurrence, disease-free survival and overall survival between laparoscopy group and laparotomy group. Conclusion: The comparison of the randomized controlled trials published before and after 2010, showed no significant difference in outcomes between the learning period and after.

INERVENTIONS OF KANCHANAR GULGULU AND VARUNADI KASHAYAM IN SUBCLINICAL HYPOTHYROIDISM (SCH) - A CASE STUDY
Authors: Renni Anita
Published: October 2021

SCH is defined as- Biochemical evidence of hypothyroidism (normal T3 &T4 but raised TSH). SCH is like-lihood of progression to clinical hypothyroidism. It may persist for years. It is more common in women than men, and its prevalence increases with age. Of patients with SCH, 80% have a serum TSH of less than 10mlU/L. The most important implication of SCH is high likelihood of progression to clinical hypothyroid-ism. The possibility that it is a cardiovascular risk factor has been a subject of debate. Currently the practi-cal approach in modern therapy is routine levothyroxine therapy for persons with a persistent serum TSH of more than 10.0mlU/L and individualized therapy for those with a TSH of less than 10.0mlU/L. There is no direct reference of thyroid in Ayurvedic classics, but the Galaganda and Gandamala have been fre-quently used in the text. According to Charakacharya presentation of multiple Granthi around the neck is called Gandamala and single swelling on the Parshva (laterals) of neck is Galagand. Galagand is ex-plained classically in all the Ayurvedic texts, including Sushruta and Ashtangahruday, Since Galagand is the most untouched topic in Ayurveda and since thyroid is becoming one of the common problems in day- to-day practice. However, in recent times it has been observed that thyroid disorders can be very well man-aged with Ayurvedic drugs, although modern drugs are quite effective in getting TSH level down but with certain adverse effects. So, a case of Subclinical hyopothyroidism was selected and observed before, and after the treatment. Kanchanar is considered as a drug of choice for Granthi (Cysts)and Galagand (Goi-tre), so here in this case Kanchanar Guggulu along with Varunadi Kashayam and Vaishwanar Choornam was administered for the purpose of Agnideepana (To improve digestive fire), & Vatanulomana ( Regular-ise Vata). The patient was followed upto 6 months to observe increase in value of TSH.

The main objective of this paper is to analyze the effect of education, age, access to ICTs and physical and financial assets, as well as other personal and socio-economic characteristics on the probability of being a formal or informal own-account worker. In order to achieve this purpose, information will be used at the urban level for the twenty-one main cities in Colombia from the Great Integrated Household Survey 2010 (GISH), by the National Administrative Department of Statistics (DANE) and the Colombian Longitudinal Survey of the University of the Andes 2013 (CLS). Based on these data, models that have a qualitative binomial and multinomial dependent variable are employed, correcting for selection bias. As main results, it was found that physical assets and access to credit have a positive marginal effect on the probability of being an own-account worker. On the other hand, the marginal effect of education was negative; the lower the educational level, the greater the probability of self-employment, especially regarding the informal work.
ICT KAO IZAZOV ILI POTREBA U POČETNOJ NASTAVI MATEMATIKE
Authors:   University of Montenegro, Faculty of Philosophy, Mićanović Veselin
Published: October 2021

The paper presents a research on the use of ICT in teaching mathematics in lower grades of elementary school. In the initial teaching of math- ematics, in spite of numerous curriculum reforms, textbooks, worksheets and workbooks remain predominantly used. Whether they are sufficient and the only source of knowledge in the XXI century is becoming a very sensitive issue. ICT on the other hand offers many possibilities and greatly facilitates the process of understanding the learned content. The aim of this paper is to examine the opinion of teachers on the use of ICT in teaching mathematics, determine the need for its use in the teaching pro- cess and identify problems that impede and/or prevent its application in the implementation of learning outcomes in mathematics at an early school age. The sample of the research included two hundred twenty teachers from first to fifth grade in six cities in Montenegro. The research has shown that ICT is needed in the organization and realization of the initial teaching of mathematics, but due to its lack in educational institutions, its use becomes impossible.

Published: October 2021

Innovation in course curriculum is a continuous process in the higher education system (HES). As the amount of published information growing with time at geometric progression, it is necessary to increase the depth and breadth of the HES curriculum of every course with time. Engineering education is one of the prominent areas in science & technology education, finding many opportunities and facing many challenges in the 21st century due to the accelerated advancement of technologies in many areas. Keeping students in pace with such developments and adopting such newly emerging areas of technology in the current curriculum is an essential requirement of the education industry’s progress. In this paper, we have proposed improvement in engineering education in India at the undergraduate level by means of six innovations to improve the depth, breadth, and vigorousness of the B.Tech. programme by suggesting a Student integrated development Framework in engineering based on STEAM-Employability Model with a focus on experimental learning. The six innovations proposed in this model upgrades the B.Tech. (Pass) programme into B.Tech. (Honours). The advantages, benefits, constraints, and disadvantages from students, institutions, and job offering industries point of view are analysed to check this model of B.Tech. (Honours) for its effectiveness in its objective of enhancing competency and employability of graduates to secure better employment.
