Published: August 2020

Sheep wool is natural, easy obtainable, renewable and biodegradable material with a perspective application as a sorbent in filters for purification of industrial emissions from various environmental pollutants. The element content and thermal stability of Latvian dark-headed sheep wool filter fibres was analysed and described before and after exposure to biomass combustion products. Based on the obtained results, it is concluded that the sheep wool filter fibres can sorb various gaseous combustion products, such as carbon monoxide (CO), carbon dioxide (CO2) and nitrogen oxides (NOx), however, the sorption processes of these gases are irreversible. The obtained results of total reflection X-ray fluorescence and inductively coupled plasma mass spectrometry suggest that the concentration of heavy metals, such as lead, zinc and iron, significantly increases in the sheep wool filter fibres after exposure to biomass combustion products. In thermogravimetric curves, no significant changes were detected for the sheep wool filter fibres after exposure to combustion products, while in differently thermal analysis curves, the formation of exothermic peak at around 580 °C was observed and could be related to autoignition. Using X-ray diffractometry and scanning electron microscopy coupled with energy dispersive X-ray spectrometry, the solid particles of biomass combustion products were observed on the scaly surface of the sheep wool filter fibres, and these particles mainly consist of potassium chloride, carbon, sulphur and various metal oxides.
Modelos económicos neoliberales y cambios constitucionales. La promoción de la mutación jurídica en la perspectiva de la comparación
Authors: Nicolini Matteo 
Published: August 2020

El ensayo trata de examinar el impacto del modelo económico neoliberal en los procesos de mutaciones constitucionales a través de un doble cambio, esto es, de perspectiva y método. El cambio de perspectiva propone abandonar las modalidades mediante las que, en la última década, se ha valorado el impacto de los factores económicos sobre cambios constitucionales. En lugar de centrarse en la crisis económica, el ensayo considera la interacción entre la Economía y el Derecho constitucional como un fenómeno históricamente recurrente y facilitador de mutaciones jurídicas. El cambio de método deriva de la aplicación de la comparación jurídica para el estudio de dichos procesos de mutación. A este respecto, la comparación propone re-imaginar política y jurídicamente la relación entre economía, democracia y cambios constitucionales. De esta manera, se propone suavizar el formalismo de la ciencia jurídica tradicional para conseguir valoraciones más amplias de los fenómenos –entre otros, económicos– que empujan a cambios en la esfera de lo jurídico-constitucional. Puesto que la relación entre mentalidad económica y mensuración cuantitativa del Derecho se expresa en gran medida a través del proceso de constitucionalización del principio del equilibrio presupuestario, el ensayo analiza la relevancia de su constitucionalización aplicando el potencial«subversivo» de la comparación: por un lado, ésta facilita el desvelamiento de las ideologías que subyacen a la mensuración cuantitativa; por otro, nos indica las modalidades por las que los actores de las finanzas globales concretan su propia agenda política procurando –o, mejor dicho, imponiendo– cambios relevantes en la esfera del Derecho constitucional.
Relación entre las familias migrantes y profesorado: Un camino por construir
Authors: Arnaiz-Sánchez Pilar , Chamseddine Habib Allah Mohamed 
Published: August 2020

RESUMEN La relación de las familias migrantes con el profesorado tiene sus propias características y peculiaridades, así como una palpable carencia de orientación psicopedagógica adecuada para fomentar el conocimiento y el reconocimiento mutuo e impulsar de esta manera la desaparición de las diferencias significativas que suelen aflorar entre ambas partes a la hora de afrontar los desafíos de la comunicación. En tal sentido, el objetivo de la investigación abordada en este trabajo, fue describir el conocimiento de la vida del centro que poseen los progenitores migrantes, el conocimiento que posee el profesorado sobre la vida del alumnado migrante y el tipo de relaciones personales que mantienen ambas partes, en centros de educación infantil y primaria de atención preferente de la Región de Murcia. Para llevar a cabo este estudio se empleó un método descriptivo e inferencial, donde se aplicaron dos cuestionarios, uno dirigido a los padres y otro a los docentes. Participaron 823 progenitores y 150 profesores. Los resultados indican que el profesorado apenas conoce personalmente a los padres varones de sus alumnos, y que las visitas de los padres por iniciativa propia continúan siendo una asignatura pendiente. Sin embargo, se aprecian avances relevantes en cuanto a la accesibilidad y predisposición para la comunicación por parte de ambas instituciones educativas, si bien queda mucho por hacer en relación a la consolidación de confianza.ABSTRACTRelationship between teachers and migrant families has its own characteristics and peculiarities, as well as a palpable lack of adequate psycho-pedagogical guidance to foster knowledge and mutual recognition, promoting the disappearance of significant differences that usually emerge between both parties when it comes to facing the communication challenges. In this sense, the research objective undertaken in this assignment was to describe migrant parents’ knowledge about life of the Centre, faculty’s knowledge about migrant students’ life and personal relationships maintained by both parties at preferential pre-school and elementary education Centre’s in Region de Murcia. In order to carry out this study, a descriptive and inferential method was used in which two questionnaires were applied, one addressed to parents and the other addressed to teachers. 823 parents and 150 teachers participated. The results indicate that teachers have little personal knowledge about their students’ male parents, and parents’ visits by their own initiative continue to be a pending subject. However, significant progress has been made in terms of accessibility and readiness for communication on the part of both educational institutions, although much remains to be done in terms of building confidence.

Published: August 2020

Background
Research indicates that school-based first aid programmes appear to improve students’ knowledge and skills. However, evidence for their effectiveness is limited by a lack of rigorously designed studies. This research used a cluster randomised crossover trial to assess the effects of two different types of first aid training on the frequency and appropriateness of older adolescents’ first aid behaviours towards their peers 12 months after training.

Methods
Schools eligible to participate were government funded and able to accommodate first aid training and survey time for two consecutive Year 10 student cohorts. Four Australian public schools were matched in two pairs and randomly assigned to receive either physical first aid (PFA) or teen mental health first aid (tMHFA) training for their Year 10 student cohort (mean age 16 years). In the second year, the new Year 10 cohort received the other intervention. Four cohorts were randomised to receive PFA and four were randomised to receive tMHFA. Online surveys were administered at baseline and 12 months after training, measuring whether students had encountered a peer needing PFA, whether they had provided PFA, what actions they performed and, if applicable, why they had been unable to help the person. Only research staff analysing the data could be blinded to measurement occasion, school identity and condition.

Results
Four cohorts received PFA and four received tMHFA. The results indicated that there were no differences between groups regarding the frequency of appropriate first aid actions performed 12 months after training. The most common types of PFA provided to a peer were sending for help and wound care. Students most commonly mentioned someone else attending to their peer or lacking skills or experience as reasons for not performing PFA actions.

Conclusions
More research that examines first aid behaviours using rigorous, longitudinal study designs is needed to establish the effectiveness of school-based first aid training for older adolescents.

Published: August 2020

ObjectiveNonacademic qualities such as time management, study skills, stress, and motivation have been linked to academic performance. The purpose of this study was to gain an understanding of this relationship to enable early remediation in a chiropractic training program.MethodsQuestionnaire data were collected at the beginning of the academic year, end of semester 1, and end of semester 2. Questions were related to participants' time management, study skills, stress, and motivation. These were compared to summative assessment results. Semistructured interviews were conducted at the end of semester 1 and end of semester 2.ResultsAmount of time spent studying did not correlate significantly with assessment results. At the beginning of the year, 85.7% of students participated in extracurricular activities. This reduced throughout the year; students who stopped activities were significantly more successful in assessments. When stress at the beginning of the year was compared to end of semester 1, there was a significant increase (p = .012), with further significant increases from semester 1 to the end of semester 2 (p = .001). Students were very motivated at the beginning of the year, and this was maintained to the end of semester 1 (p = .257). However, at the end of semester 2, students became significantly less motivated (p = .007). End-of-year motivation correlated with poor student outcomes (p = .056).ConclusionTime management, study skills, stress, and motivation influenced academic performance in this sample of students. This study supports the notion that student assistance is needed. Additional research into student assistance would be beneficial.

Parents play a vital role in increasing the performance and ensuring the good manners of their children in school. In the context of Indigenous People (IP), parental participation in educating their children is a meaningful involvement that benefits student learning directly. This study aims to determine the parental involvement of indigenous people in selected elementary schools in Northern Part of Mindanao, Philippines. The study specifically identified the profile of the IP parents, parents’ contributory factors and involvement on the aspect of communication, learning at home, and financial support. The extent of parental involvement on the behavior of their children and significant relationship between respondents’ profile were also measured. The study utilized a descriptive-quantitative method to explore how the IP parents extend their support to their children through survey, actual visitation and interview to validate the accuracy of the data gathered. Selected IP parents from IP elementary schools were surveyed using a researcher-made questionnaire as the main tool in the study. Data were analyzed using frequency counting, simple percentage, weighted mean, and Pearson R correlation.
The IP parents fall to marginal classification in terms of educational background (45.83% are elementary undergraduate) with monthly income of less than fifteen thousand (less than the minimum wage). Regardless of race and background, IP parents’ instincts are the same with common parents in supporting their children in school-related activities. However, issues on communication, learning at home, and financial support extended by IP parents to their children still need to be improved. In addition, parents’ involvement influence academic endeavor of the students because they are given chances to enjoy the opportunity of free and supportive education. Thus, parents should constantly monitor the performance of their children at school to help them improve in their studies and build confidence to do better.

Turmeric spice has a diverse array of biological activities. The present study evaluated body weight and haematological impact of Curcuma longa (Turmeric) in male albino rats using standard analytical methods. Twenty four healthy male albino rats were used for the study. Results shows no significant increase in body weight in the first week of dieting while a gradual increase was observed with increasing weeks of dieting. Treatment with the powder did not significantly (P ≥ 0.05) alter the levels of hemoglobin (Hb), red blood cells (RBC) and means corpuscular volume (MCV) of the rats. The result also showed a significant (p ≤ 0.05) increase in the platelets and mean corpuscular hemoglobin concentrations (MCHC). However, the white blood cells (WBC) and the packed cell volume (PCV) concentrations were slightly reduced. This study suggests that adding Curcuma longa (Turmeric) at 50, 100, 200 mg/kg body weight within the duration of study could positively affect the hematological parameters and general well being of the body.

Background: Molecular docking has been used recently in pharma industry for drug designing, it’s a powerful tool to find ligand-substrate interactions at molecules level. Since urgent need to develop anti-viral drug that target new coronavirus main proteins, in silico docking has been used to achieve this purpose.
Materials and Methods: Thirteen herbs are known for their antioxidants and antiviral properties have been selected to investigate their abilities in inhibiting SARS-COV2 spike protein and main protease Mpro. pdb files for RBD (Receptor Binding Domain) region of spike protein and for Mpro and mol2 files for all herbs understudy were uploaded for swiss dock online server, the docking results were analyzed using chimera software. Full fitness energy and hydrogens bonds interactions were considered for docking evaluation. Pharma kinetic properties for compounds have good binding results were evaluated through AMES and ADMET tests.
Results: All compounds showed negative full fitness energy that means they are able to complex with both SARS-COV2 spike protein and main protease, however some of the herbs form very powerful hydrogen bonding with the RBD site of the spike protein and the catalytic site of Mpro such as coumarylquinic acid, while stigmasterol has strong binding with the spike protein only. Both compounds appear to be safe drugs for human according to AMES test results.
Conclusion: Coumarylquinic acid and stigmasterol have powerful binding in silico, further in vitro studies include using viral infected human lung cells and testing above compounds ability for inhibiting viral entry and replication should be proceed to confirm the study results.

Aim: The knowledge of genetic diversity and relationship among the genotypes play a significant role for genetic enhancement in breeding programmes to increase production, improve quality, biotic and abiotic stresses, and also for the selection of superior parental lines in rice. The present field experiment was conducted to study the diversity present in 29 local genotypes of rice using both morphological and molecular ways.
Methodology: The experiment was conducted at Agricultural Research Farm, Banaras Hindu University, during Kharif-2017 in an augmented block design with 29 rice genotypes including 3 checks. Mahalanobis’ D2 analysis was carried out to assess the morphological diversity present among the genotypes and molecular analysis was done with 21 polymorphic SSR markers using the NTSYSpc software.
Results: Mahalanobis’ D2 grouped the 29 genotypes into 6 clusters based on the inter-se genetic distance. The highest intra-cluster distance was recorded in the Cluster I (32.73), which comprised of 7 genotypes. The highest inter-cluster distance (65.86) was observed between Clusters IV and V. Molecular diversity analysis grouped the 29 rice genotypes into 2 main clusters i.e. cluster I and cluster II with dissimilarity coefficient of 0.34, which were further divided into sub-clusters. Polymorphic Information Content (PIC) value is an evidence of diversity and frequency among the varieties. The level of polymorphism varied from 0.164 to 0.694, with an average 0.521. The highest PIC value was observed for locus RM 5 (0.694) followed by RM 510 (0.692). All the 21 primers showed polymorphism and the number of alleles ranged from 2 to 4 with an average of 3.04.
Conclusion: This study established the presence of considerable amount of genetic diversity among the genotypes studied, the most diverse genotypes being Anupam gold and HUR-1309 followed by Kalanamak-2 and HUR-1304. Breeders may attempt hybridization among the above genotypes which showed maximum diversity, for creating more variability in rice and can be used for planning further breeding programmes.

Published: August 2020

Cooperative Societies are grass root organization of group of people united with collective responsibilities to meet their common economic, social and cultural needs which run with philosophy of self-reliance and mutual help. It helps in agricultural development supporting critical inputs supply (seeds, fertilizer, pesticides, credit), storage facilities like Go downs, agro processing facilities and marketing the agro produce. Since 1904, the cooperative moment took stardom and the five year plans and Government legislation have integrated them into the policies for self-reliant rural growth and development. Agricultural cooperative societies dealing with inputs and credit disbursement, processing cooperatives such as Sugar Cooperatives, Dairy cooperatives etc. flourished with their consumer products whereas KRIBHCO, IFFCO became successful large cooperatives in marketing their fertilizers to their farmer members and outsiders act as a business enterprise. Status of Primary Agricultural Cooperatives Societies (PACS) reveals 19% of total PACS potentially viable, 49% running in profit, 45% small farmers’ borrower from societies. Several challenges like lack of professionalism, lack of infrastructure, political interference, nepotism, unawareness of members, meager shareholding, overdependence on financing agencies for credit, poor recovery are hindering the sustainability of societies. Certain restructuring with policy intervention like reducing state control, increased professionalism, good governance, raising share capital, quality assurance with competitive product & service, multi-purpose support system, will act as vibrant social enterprise with public trust as Government sector initiative in the locality converged with other agencies.

Published: August 2020

Field studies were carried out in 2017 and 2018 at Agricultural Research Farm, Banaras Hindu University Varanasi, Uttar Pradesh, India, to evaluate the effect of natural mulching and herbicides on weed dynamics and growth of rice. The experiment was laid out in a split plot design with three mulching treatments viz. no mulching, cover crop of Sesbania followed by green mulch and rice residue mulch (5 t/ ha) in main plots and five weed management treatments, viz. weedy, two hand weeding, post-emergence application of bispyribac Na 25 g/ ha, penoxsulam 30 g/ ha and tank mix bispyribac Na 25 g/ ha + pyrazosulfuron 20 g/ ha at 18 DAT in sub plots. Combination of main plot treatments and sub plot treatment allocated randomly and all the treatment combination were replicated thrice. The study revealed that mulching with Sesbania provided effective control of weeds, recorded significantly higher growth attributes and biological yield as compared to no mulching in both the years. Among weed management treatments two hand weeding resulted significant reduction in density and dry matter of weeds and increased yield which was at par with post-emergence application of penoxsulam 30 g/ha in both the years Treatment combination of surface mulching of Sesbania with two hand weeding recorded significantly higher number of tillers, as compared to other treatment combinations, it was at par with combination of surface mulching with Sesbania and post-emergence application of penoxsulam 30 g/ha and rice straw mulching and post-emergence application of penoxsulam 30 g/ha.
An Optimal Algorithm for the Solution of the Helmholtz Equation
Authors: Akinola Richard O. , Ogbeh Blessing Okwudo , Chukle Isaac 
Published: August 2020

Aims/Objectives: The Helmholtz equation is a partial differential equation which is used in numerical weather prediction. Angwenyi et. al., used a five point finite difference stencil in discretizing the partial differential equation and solved the resulting square system of equations using eight iterative methods and concluded that the BICGSTAB was the most computationally efficient using just one example. However, based on a comparison of the norm of the residual and CPU time of four methods presented in this work on the same example in their paper and others; we not only discovered that the Gauss Seidel method out performed the BICGSTAB contradicting the claim of the authors but also the Thomas Block Tridiagonal Algorithm (TBTA)in the absence of round off errors.Methodology: We compared the performance of the Gauss Seidel Method, BICGSTAB, Matlab backslash, and the Thomas Block Tridiagonal Algorithm (TBTA) for the numerical solution of the Helmholtz equation with different step sizes.
Results: We discovered that in the absence of round off errors, not only did the Gauss Seidel method but also the Thomas Block Tridiagonal Algorithm (TBTA) out performed the BICGSTAB contradicting the claim of Angwenyi et. al.Conclusion: We do not recommend the BICGSTAB for the solution of the linear system of equations arising from the discretization of the Helmholtz equation as claimed by Angwenyi et al. Rather, the Thomas Block Tridiagonal Algorithm should be used and if one is thinking of an iterative method for the numerical solution of the Helmholtz equation, the Gauss-Seidel method should be the method of choice rather than the BICGSTAB.
