Authors: Khodadad Kashi Sholeh , Saatchian Vahid
Published: May 2023

The purpose of this research was to investigate the effect of psychological empowerment on human resource retention in selected sports federations, with the role of emotional commitment as a mediating factor. A cross-sectional study was carried out. The statistical population of the study (270 employees) was all official staff of five selected federations (wrestling, volleyball, taekwondo, soccer and swimming). Based on the Morgan table, 175 individuals were selected as the statistical sample. In order to assess the studied variables, Spritzer's psychological empowerment questionnaire (1995), Allen and Meyer Commitment Measurement Questionnaire (1991), and Kaident’s staff retention questionnaire (2009) were used. The reliability of the questionnaires was 0.89, 0.87, and 0.84, respectively. In order to analyze the data, descriptive and inferential statistics (Kolmogorov Smirnov, Pearson Correlation Coefficient, Path Analysis Model) were used. The results showed that there is a statistically significant positive correlation between psychological empowerment and human resources maintenance (0.56). Emotional commitment with an impact factor of 0.35 plays a mediating role in relation to psychological empowerment in human resource retention. Therefore, the officials of sports federations can improve the maintenance of human resources by establishing a complete and desirable psychological empowerment and paying attention to the concept of emotional intelligence at the organization level.

Published: May 2023

In general, football is considered a male-dominated sport but recent trends show a significant improvement in women’s participation in the sport. The aim of this study was to identify and explain the reasons for women’s participation in football in Indonesia. A cross-sectional study was conducted with 29 female athletes of the Indonesian women’s national football team using the Participation Motivation Questionnaire (PMQ) assessed by Guttman scale. The data was analyzed using a descriptive percentage approach and then grouped based on participation criteria. The results showed that more than half of the women participants in football in Indonesia were 17 years old (53%) and had a senior high school education (66%). Most of the time, women participants were encouraged by peers (87%), parents (86%), facilities and infrastructures (97%), awareness (76%), interest (79%), attachment (87%), and loyalty (90%). Participation rates were also influenced by the existence of football clubs (100%) and the training programs implemented (100%). It is concluded that women’s football participation in Indonesia is largely influenced by micro-level factors (peers and parents), macro-level factors (existence of football clubs, their facilities and infrastructures, and their training programs), and psycho-sociological factors (awareness, interest, attachment and loyalty).

Published: May 2023

The purpose of this study was to investigate the role of training programs approved by the Athletics Federation on the performance of coaches in Iraq and also to develop a model for evaluating the performance of athletic coaches. A cross-sectional study was carried out. A total of 60 experts from the Athletics Federation participated in the study. To collect data, a modified questionnaire by Mohammadi (2016) was used. The face and content validity of the questionnaire was confirmed by sports management professors and its reliability was higher than 0.7. In order to analyze the research data, the Statistical Package for the Social Sciences (SPSS version 22) was used, and to perform structural equations and model presentation the AMOS software was used. Based on the results of the exploratory factor analysis, eight factors were identified, which in order of priority included technical skills, management skills, classroom teaching techniques, motivational skills, individual and moral characteristics, sport characteristics and work experience, emotional and human characteristics and social characteristics. Also, the results of the structural equation modeling test showed that all factors were statistically significant (p = 0.001) and the research model had a good fit. Regarding the results of the research, it was concluded that for coaches to perform more successful, technical and management skills should be given more importance than other factors. The role of athletics programs in training coaches is also very important. Therefore, developing the capabilities of coaches is not possible without using a system of monitoring and evaluating performance.

Authors: Abdelhaleem Mahmoud Diab , Grase Mariam Omran , Aly Sobhy Mahmoud , Abdallah Ehab Ali
Published: May 2023

There is growing evidence that supports the correlation between incidence of ankle dysfunction and low back pain (LPB). Although the spine and ankle seem like distant regions of the body, they are functionally connected by the lower extremity kinematic chain. The aim of the current study was to investigate the association between functional ankle instability (FAI), limited ankle dorsiflexion (DF) range of motion (ROM) and (LPB). One hundred two subjects with chronic ankle sprain pain participated in this study. The mean ± SD age, weight, height, and BMI of the study group were 43.5 ± 12.96 years, 85.27 ± 14.22 kg, 172.9 ± 8.45 cm, and 28.59 ± 4.72 kg/m². LPB was measured by Visual Analogue Scale (VAS), FAI was measured by the anterior drawer test and DF ROM was measured by the lunge test. All statistical analyses were performed using the Statistical Package for Social Studies (SPSS) version 25 for Windows. There was no statistically significant association between pain and age, pain and BMI, pain, and sex (p > 0.05). There was a statistically significant association between pain and drawer test (odd ratio 5.68, p = 0.02) and a statistically significant association between pain and DF ROM (odd ratio 1.16, p = 0.01). The current study supported previous studies recommending FAI and limited ankle DF ROM as a factor in LPB. The authors suggest conducting similar studies with a larger number of participants and include functional measures scales or questionnaires to increase the validity and generalizability of the results.

Published: May 2023

The aim of this study was to identify the reality of the level of professional pressures during the use of e-learning among teachers of the Faculties of Physical Education and Sports Science in Baghdad. A cross sectional study was carried out and the descriptive approach was adopted in a survey method on a sample of 120 faculty members of the Faculties of Physical Education and Sports Sciences in the Universities of Baghdad Governorate (Baghdad Al-Jadriya, Baghdad for Girls, Al-Mustansiriya). The two researchers used the “Occupational Stress Scale” as the main instrument for measurement in the study and it was applied to the study sample for a period from 18/04/2021 until 27/05/2021. The Statistical Package for Social Sciences (SPSS, version 26) was used for data analysis. The results showed that the members of the teaching staff in the Faculties of Physical Education and Sports Sciences have a high level of occupational pressure (p < 0.05), with an increase of the undesirable level of pressure on relationships and communication with members of the staff teaching and students. In conclusion, faculty members in the Faculties of Physical Education and Sports Sciences have an undesirable level of occupational pressure and a high level of stress when they use e-learning method of teaching. It is necessary that universities and colleges, when organizing the schedule and duties assigned to the faculty members who teach their students online, take care to reduce the burdens that lead to an increase of occupational pressures, as this has a negative impact on them.

The primary objective of this study was to identify the obstacles and problems encountered in the work of sports clubs according to the reality of the application of administrative automation. The present study was conducted in the sports club headquarters of Baghdad within the timeframe of October 2021 to December 2021. In the present study, a descriptive approach was used by the researchers in an analytical style according to the nature of the problem to be studied. The research community of the current study was composed of 100 sports clubs in the governorate of Baghdad. A total of 80 questionnaires were filled by the sample participants, who represented a percentage of 80% of the research community. After processing the results statistically using the SPSS software, the researchers concluded that sports clubs encounter a lot of difficulties regarding delay in implementing automation procedures in their administrative work, due to lack of financial allocations and lack of awareness among club workers regarding automation techniques.
Evaluating the Feasibility of Hybrid Ventilation in Educational Spaces: A Simulation Study in the Northern Basque Country Climate
Authors: Rodríguez-Vidal Iñigo , Armengod Unai , Otaegi Jorge
Published: May 2023

This paper delves into the examination of indoor comfort in classroom environments and its interplay with ventilation on human wellbeing in scenarios of varying indoor carbon dioxide concentrations. The assessment of these parameters was done according to the provisions outlined in the Spanish national Regulation of Thermal Installations in Buildings (RITE). This study also compares various ventilation strategies, namely natural, mechanical and hybrid ventilation, commenting the pros and cons of each method in the climate of the Basque Country, Spain. To do so, a classroom in the School of Architecture of San Sebastián was modelled in thermal simulation software. Simulations were carried out for full days in 5-minute intervals using Design Builder, and considered three different exterior scenarios (a cold day, temperate day, and a warm one) and three different ventilation systems (natural, mechanical with heat recovery, and hybrid). Two additional scenarios where added for control, one with no ventilation at all and another with a partial, constant, natural ventilation, like was done during the COVID-19 pandemic. Thus, the natural ventilation option was evaluated under three conditions (windows always closed, windows open 15%, and windows operated by thermal sensation of the user). The mechanical system evaluated consisted of a constant flow ventilation for IDA 2 IAQ with an airflow of 12.5 l/s·person. The modelled hybrid system consisted in a combination of simple flux mechanical ventilation and open windows and doors under some particular conditions. An occupancy rate of 50% of the theoretical maximum occupancy of the classroom and a heating setpoint of 15ºC were considered. This article presents the CO2 concentration, final energy consumption and thermal comfort results obtained in the simulation and compares between the different scenarios. The results showed that the hybrid ventilation system was able to effectively control indoor air quality, providing a healthy and comfortable environment for occupants. The hybrid system demonstrated improved energy efficiency compared to the natural ventilation system, while maintaining a high level of indoor air quality. Overall, the results of this study highlight the importance of considering hybrid ventilation in educational spaces in the northern Basque Country climate. The study provides valuable insights for building design and operation, especially for renovation of existing schools and educational facilities that lack any means of mechanical ventilation, showing some of the potential for hybrid ventilation to improve indoor air quality and energy efficiency.
Exploring the Differential Effects of Urban Heat Islands on Energy Use and Carbon Emissions in Warm and Cold Climates: a Case Study of North Africa and North Europe
Authors: Haine Kamel , Blumberga Dagnija
Published: May 2023

The urban heat island (UHI) phenomenon has differential impacts on energy use and carbon emissions in buildings depending on the climate of the region and the urban planning strategies in place. This study explores the differential effects of UHI on energy use and carbon emissions in warm and cold climates, using North Africa and North Europe as case studies. We address the following research questions: 1) How does the UHI phenomenon impact energy use and carbon emissions in buildings in these regions? 2) What urban planning strategies are currently in place to mitigate the negative impacts of UHI on energy demand and emissions in these regions? 3) How effective are these strategies in mitigating the negative impacts of UHI on energy demand and emissions in both warm and cold climates? 4) What additional urban planning strategies could be implemented to reduce further the negative impacts of UHI on energy demand and emissions in both warm and cold climates? The UHI increases energy bills and emissions due to the higher demand for cooling energy in warm climates, while in cold climates, UHI reduces energy demand and emissions by decreasing the need for heating energy. Urban planning strategies, such as incorporating green space, using reflective materials, choice of colors, and designing for natural ventilation, can effectively mitigate the negative impacts of UHI on energy demand and emissions in both warm and cold climates. However, the effectiveness of these strategies varies depending on the climate of the region and the specific urban context. In this study, we will provide a recommendation for urban planning strategies that can be implemented to further reduce the negative impacts of UHI on energy demand and emissions in both warm and cold climates. Our study contributes to the understanding of the UHI phenomenon. It provides insights for urban planners and policymakers in developing effective strategies to reduce energy use and carbon emissions in buildings and cities.
Numerical Model and System for Prediction and Reduction of Indoor COVID-19 Infection Risk

Published: May 2023

Airborne aerosol transmission is a significant route of SARS-CoV-2 and other viruses in indoor environments. The developed numerical model assesses the risk of a COVID-19 infection in a room based on the measurements of temperature, relative humidity, CO2 and particle concentration, as well as the number of people and occurrences of speech, coughing, and sneezing obtained through a dedicated low-cost sensor system [1]. As the model operates faster than real-time, it can dynamically feed this information back to the measurement system or building management system, and it can activate an air purifier with filtration and UV-C disinfection when the predicted infection risk is high. This solution enhances energy efficiency as (1) lower ventilation intensity is necessary in the cold season to reach the same safety level and (2) the purifier is activated only if the predicted infection risk is above a certain threshold.The model is integral and takes into account the average values of simulated variables. However, it considers the inhomogeneous vertical distribution of concentration of droplets and aerosol particles. The droplets expelled by a potentially infectious person at a certain height through breathing, speaking, coughing, and sneezing are characterized by the total amount of expelled liquid, droplet size distribution and virus particle concentration. The rate of droplet evaporation depends on the temperature and relative humidity. Droplets are redistributed within the room vertically through turbulent diffusion and gravitational force. If the final droplet diameter is less than 5 mm, these particles are considered airborne and can leave the room only by ventilation, filtration, or by sedimentation on surfaces through Brownian diffusion. As a person in the room inhales these droplets and aerosols, the risk of infection increases as the number of absorbed virions grows, with the probability of infection being 50% when 300 virions have been inhaled.The parameter studies using the model indicate that the coughing and sneezing events greatly increase the probability of infection in the room, therefore the identification of these events is crucial for the applied measurement system. A method for determining the unknown ventilation intensity by measuring the number of people and the CO2 concentration is proposed and tested.

Способност дефинисања појмова је један од показатеља лексичко-се- мантичке развијености дјеце млађег школског узраста. Дисграфија је поремећај писаног изражавања за који је карактеристично да је вјештина писања знатно испод очекиваног, с обзиром на хронолошки узраст дјетета, просјечну или натпросјечну интелигенцију, одго- варајуће сензорно и моторно функционисање и адекватне услове за учење. Основни циљ истраживања био је испитивање способности дефинисања појмова код дјеце са дисграфијом. У истраживању је ко- ришћен Тест за испитивање говорне развијености/Тест дефиниција, којим се процјењује лексичко-семантичко функционисање испитани- ка. Истраживање је спроведено у три основне школе у Источној Хер- цеговини, школске 2016/2017. године. Узорак је обухватио 84 испита- ника, 42 ученика са дијагностикованом дисграфијом који су чинили експерименталну групу и 42 ученика са складним рукописом који су чинили контролну групу. На основу резултата нашег истраживања закључили смо да дјеца са дисграфијом имају значајно слабије развије- ну способност дефинисања појмова у односу на дјецу са уредно развије-ном способношћу писања. Наведено се огледа у квалитету добијене дефиниције и њеној дужини. Ови налази указују на потребу пружања додатне подршке у развоју лексикона и богаћењу рјечника код дјеце са сметњама у писању.

Febrile neutropenia occurring during chemotherapy was reported to be a predictor of survival in breast cancer patients. We assessed the incidence of febrile neutropenia induced by chemotherapy. Data from a retrospective study on the application of chemotherapy protocols in breast cancer patients was reviewed. Analyzing the data, we can see that out of 81 patients who received chemotherapy, 43 were diagnosed with neutropenia and 4 or 9.3% of those patients were diagnosed with neutropenia again despite prophylaxis with Granulocyte-colony stimulating factor (G-CSF). In 4 or 9.3% of patients, further administration of that chemotherapy protocol had to be stopped due to severity of neutropenia and complications they caused. During the treatment, grade IV neutropenia was diagnosed in 27 or 63% of patients while grade I neutropenia was diagnosed in 2 or 4.65% of patients. Anemia associated with neutropenia was also diagnosed in 7 or 16.3% of patients while pancytopenia was diagnosed in 4 or 9.3% of patients, and thrombocytopenia associated with neutropenia was diagnosed in only one patient. The hazard ratio of febrile neutropenia presence compared to the absence of such toxicity was adjusted. The cox model was 0.75 (confidence interval 95% 0.54-0.95; P=0,0189) for grade I neutropenia, 0.63 (0.50-0.78; P0,0001) for grade II neutropenia and 0.71 (0.51-0.98; P=0.3888) for grades III and IV neutropenia. These results suggest that the occurrence of neutropenia during chemotherapy is an independent predictor of increased survival in breast cancer patients, while the absence of such toxicity indicates that the drug doses are not sufficient. Monitoring of febrile neutropenia in patients treated with chemotherapy may contribute to improved drug efficacy and better survival rate.

The municipal solid waste (MSW) landfill is recognized as an anthropogenic source of air pollutants that can have a negative impact on human health and the environment. Workers who work at the MSW landfill may be exposed to risk due to the inhalation of substances such as volatile organic compounds (VOCs). Although VOCs account for 1% in landfill gas, they are important because of the high level of toxicity associated with them. Regular monitoring of air quality and risk assessment provides important information in protecting the health of workers at the landfill. This study focuses on a health risk assessment related to VOCs (benzene, toluene and xylene) exposure via inhalation for workers at a landfill Banja Luka, Republic of Srpska, Bosnia and Herzegovina. Additionally, cancer risk and non-cancer risk of benzene, toluene and xylene of workers indicated that occupational exposures were above recommended standard. This implies that landfill workers are exposed to a significant health risk associated with inhalation exposure to VOCs

Authors: Ataman Yurii , Brizhata Iryna
Published: May 2023

The research topicality is needed to diagnose in time and correct properly athletes’ autonomic dysfunction (especially among sportspeople with pre-pathological states). The study of latent hemodynamic changes and detection of dysautonomia among prehypertension athletes (particularly those who train heavily) is a promising way to raise sportsmen’s health and achievements. The research purpose is a hemodynamic profile study of athletes with office prehypertension during different training macrocycle periods. Methods. The research comprised 30 athletes of acyclic activity. Their average age was 23.1 (2.71) years. Females were nine individuals (30%). We monitored arterial blood pressure and heart rate in each macrocycle period, carried out the dysautonomia test and established anamnesis and complaints. Results. For prehypertension athletes, the most challenging moment was the competition period. Therefore, the systolic arterial hypertension rate within preparation, competitive and transition training periods was 17%, 47% and 7% (χ2=14.53; р0.001) while the diastolic one was 17%, 37% and 7% respectively (χ2=8.75; р=0.012). Significantly, we observed an increasing possibility of arterial blood pressure rise over normal values among dysautonomia athletes during the competition period (RR=3.27 (р=0.01); OR=8.33 (р=0.006)). However, during the preparation and recovery periods, arterial hypertension possibility was not significant (р0.05). Conclusions. In the competition period of training macrocycle is highly expectable development of arterial hypertension of latent course in athletes with office prehypertension. Besides, the relative risk of latent arterial hypertension in extra-training time increases if there are other symptoms of dysautonomia, but these changes are not persistent. However, their proper diagnosing and correcting may lead to athletes’ better health and achievements.

Published: May 2023

There was a lack of empirical comparison of the concurrent strength effects of High-Intensity Interval Training and Game-Based Training in the context of youth soccer players. Objective: The main purpose of this study was to examine the effects of those two types of training within six week-period of cardio activities performance characteristics of male junior high school soccer players in Kediri, East Java. Methods: By applying a quantitative approach and experimental research design, this study took 20 male junior high school soccer players with a mean age of 14.5-year-old to fulfill the requirement that the samples were in the youth stage and were accustomed to a training workload and involved in soccer training and matches for at least two years to meet the minimum criteria. The research instruments were the pre-test and post-test to measure the O2max of the research subjects. Results: For 6 weeks, the subjects performed HIIT at close to ~85% of maximal heart rate while the GBT intensity was set at 70-75% of maximal heart rate. The findings implied that students with HIIT were more likely to have a greater heart rate during the study and training to get into the local tournament. Also, sprinting performance increased significantly in both groups from pretest to post-test without any changes in running performance. Conclusion: These findings may become the reference to conduct further research on different characteristics of subjects or other areas of study.

Olfactory receptor (OR) choice represents an example of genetically hardwired stochasticity, where every olfactory neuron expresses one out of ~2000 OR alleles in the mouse genome in a probabilistic, yet stereotypic fashion. Here, we propose that topographic restrictions in OR expression are established in neuronal progenitors by two opposing forces: polygenic transcription and genomic silencing, both of which are influenced by dorsoventral gradients of transcription factors NFIA, B, and X. Polygenic transcription of OR genes may define spatially constrained OR repertoires, among which one OR allele is selected for singular expression later in development. Heterochromatin assembly and genomic compartmentalization of OR alleles also vary across the axes of the olfactory epithelium and may preferentially eliminate ectopically expressed ORs with more dorsal expression destinations from this ‘privileged’ repertoire. Our experiments identify early transcription as a potential ‘epigenetic’ contributor to future developmental patterning and reveal how two spatially responsive probabilistic processes may act in concert to establish deterministic, precise, and reproducible territories of stochastic gene expression.
Comprender o interpretar el Derecho. El convencionalismo semántico en su laberinto.

En diálogo con la teoría interpretativa de Andrei Marmor, se analizan las con-diciones lógicas que aseguran la inteligibilidad de todo discurso jurídico, y su posibilidadde ser comprendido, y se defiende la tesis de la conexión necesaria entre comprensión yrealismo semántico. A partir de esta tesis se arguye que en la misma medida en que los dis-cursos jurídicos se arrogan el poder de crear autónomamente su propio significado, pierdeninteligibilidad y disminuyen sus chances de ser comprendidos. Esta tesis general se sustentaen dos argumentos. Primero, el argumento de la oscuridad de la referencia de los conceptos(en sentido amplio, incluyendo a los enunciados) cuyo significado se asume como netamenteconvencional. Segundo, el argumento de la imposibilidad de salvar la comprensión de losconceptos netamente convencionales del trilema de Münchhausen.

Published: May 2023

Teniendo a la vista diversos desarrollos dogmáticos comparados que justifican la generalización del control de contenido de cláusulas no negociadas, se examina el ámbito subjetivo de aplicación del referido control en el Derecho chileno, revisando tanto las disposiciones que se refieren expresamente a él como las reglas y principios de Derecho civil que permitirían su generalización. Se sostiene que las reglas que expresamente permiten alguna medida de control no son especiales, sino más bien concreciones de una regla general presente en el Derecho civil.

A instalação de um empreendimento em um local implica em riscos específicos, sendo por tanto necessário à identificação desses riscos no espaço urbano onde se pretende construir o empreendimento, não esquecendo que durante a construção poderá agregar riscos aos já existentes antes das obras de instalação, assim como geração de tráfego e aumento dos níveis ruído por consequência. Os impactos mais comuns nas instalações de novos empreendimentos estão relacionados à demanda por todos os bens públicos ou privados de utilidade pública destinado à prestação de serviços necessários ao funcionamento das cidades, implantados mediante autorização do poder público em espaços públicos e privados, além da poluição e degradação ambiental, aumento do tráfego, dificuldade da fluidez na cidade e impacto sonoro com incomodo aos munícipes. A implantação do Estudo de Impacto de Vizinhança no Brasil torna-se de fundamental importância por se tratar de um instrumento legal e normativo para o uso do solo urbano, implantado no país ocorrido em 2001, com a promulgação da Lei 10.257, denominado Estatuto da Cidade. A importância específica do Estudo de Impacto de Vizinhança quanto ao tratamento do impacto sonoro na instalação de novos empreendimentos, está destacada e dirigida desde a fase de implantação, sendo necessário um levantamento através de avaliações dos níveis de ruído a fim de conhecer as vulnerabilidades da região onde o estabelecimento será implantado, bem como posteriormente ser periodicamente avaliado para estabelecer medidas de controle das emissões sonoras.

Authors: Norbu
Published: May 2023

The primary objective of the study is to determine the perception of teachers on the impact of walk-in classroom observation practiced by principals and vice principals as a part of instructional leadership roles. The walk-in classroom observation system was implemented in 2022 by the Ministry of Education and Skill Development (MoESD), Bhutan. This research utilized a mixed-methods approach, consisting of both quantitative and qualitative studies. The quantitative study was conducted using 5-point Likert scale survey questionnaires for walk-in classroom leadership practice and its impact on instruction and pedagogy. The qualitative study was conducted using a semi-structured interview. The study used 90 teacher participants purposively selected from 10 schools under Trashiyangtse Dzongkhag, Bhutan responds to the questionnaires and 10 teachers selected randomly for interviews. The quantitative data were analyzed and interpreted using descriptive statistics such as mean and standard deviation while deductive coding and thematic analysis were used to analyze interview data. The findings of the study revealed that teachers generally had a positive perception of the impact of walk-in classroom observation on classroom instruction and pedagogy with an overall mean score of 3.47 and SD=1.110, as indicated by their agreement with the survey questionnaires. Further, the results from the interview indicated that walk-in classroom observation had a positive effect on lesson planning, delivery, and professional development for teachers. However, teachers are of the view that instructional leaders need to be professionally competent in subject content and pedagogical knowledge for effective walk-in classroom observation. Therefore, the findings contribute to the enhancement of knowledge and pedagogical skills and informed the leaders to bring forth the strengths and weaknesses in the common forum for deliberation and necessary changes.

Cowpea is a nutritional grain consumed especially in developing countries of the tropical and subtropical regions. It is prone to attack in its entire stages of growth by pathogens and pests such as bacteria, viruses, fungi and insects. Organisms, whether microbes, plants or animals interact both in isolated and complex systems. These interactions could be plant-plant, plant-microbe, microbe-microbe or microbe-microbe-plant interaction to complete the process of the food web. While some interactions are healthy and beneficial to the parties involved in the relationship, some others are unhealthy and harmful. This review has as its focus microbe-microbe interaction and effects on nodulation and yields of cowpea, with a view to examining the impacts on the sustainability of the food production system. A good knowledge of such interactions could help improve productivity and may allow the development of new strategies for plant protection and the control of parasites as well as for increasing crop yields. Hence this article assesses the influence of rhizobium and virus on cowpea nodulation and yields with a view to evaluating their contributory effects and assessing their individual potency in the interaction.

The availability of quality fodder in good quantity is necessary to improve the productivity of the animal. Since India place 2nd in population around the world, so to address the need for milk, the requirement of good quality fodder is necessary. In our country, there is a shortage of quality fodder due to less work being done to improve its quality and availability of lesser areas of land for its cultivation. This review paper goes through the previous work done to analyse the effect of combined nutrient sources. The application of inorganic nutrients with the combination of organic nutrients leads to improve crop yield with improvement in soil health and its productivity without deteriorating the environmental conditions. Soil is the primary source of nutrients for crops, and any degradation of the soil can result in a decrease in crop yield. Therefore, it is necessary to implement Integrated Nutrient Management (INM) practices to ensure the sustainability of natural resources and increase crop productivity.

Aim: This study was designed to assess the effect of vitamin E supplement on Creatine Kinase (CK-MB) C - reactive protein, (C-RP), urea and creatinine of albino rats fed with high fat diet.

Methodology: A total of twenty (20) albino rats of both sexes were used in this study. They were grouped into four (4) groups comprising of five (5) rats each. Group 1 was fed with normal diet; group 2 with normal diet and treated with vitamin E supplement (70 mg/kg); group 3 was fed with high fat diet only, while group 4 was fed with high fat diet and treated with vitamin E supplement (70 mg/kg). The treatments were administered daily using oral gavage method for a period 21 days. After the experimental period, the animals were sacrificed and blood samples collected for the analysis of CK-MB, CRP, urea and creatinine respectively using ELISA and colorimetric method with a spectrophotometer. Data generated were analyzed statistically using SPSS version 20 and P = 0.05 was considered statistically significant.

Results: The results revealed a significance difference in C-RP (mg/l) levels (P < 0.001) amongst the groups with a decreased C-RP levels in group 2 (1.43 ± 0.39) compared to group 1 (1.94 ± 0.53), then in group 4 (2.27 ± 0.53) which is also decreased compared to group 3 (3.31 ± 0.63). For CK-MB  there was also a significant difference among the different groups. In group 2, it was 1.94 ± 0.65 ng/ml which was decreased compared to group 1 (2.22 ± 0.55), and group 4 (2.74 ± 0.68) compared to group 3 (3.31 ± 0.62). For the urea and creatinine results, there was no significant difference (p > 0.05) among the groups when the mean levels were compared.

Conclusion: This shows that administration of vitamin E to rats fed normal or high fat diet could significantly reduce the plasma levels of CRP and CK-MB hence having some ameliorative effects on high fat induced inflammatory and cardiovascular risks or conditions.
