Authors: Vakili Amir , Zomorodian Seyed Mohammad Ali , Totonchi Arash
Published: September 2021

The accurate predictions of load- deflection response of the pile group are necessary for a safe and economical design. The behavior of piles under the lateral load embedded in soil, is typically analyzed using the Winkler nonlinear springs method. In this method, the soil-pile interaction is modeled by nonlinear p-y curves in a way that the single pile p-y curve is modified using a p-multiplier (Pm) for each row of piles in the group. The
average Pm is called the group reduction factor. The Pm factor depends upon the configuration of pile group and the pile spacing (S). The present study was conducted
to investigate the effects of various parameters, such as the pile spacing in the group, different layouts and the lateral load angle (Ѳ) change as a new parameter on the Pm factor and group efficiency based on the 1-g model test. The Pm factor is well comparable with the results of the full-scale test on pile group. However, based on the
results, the calculated values of the Pm factor for 3×3 pile groups under 2.5-diameter spacing was estimated about 0.38 and under 3.5-diameter spacing was estimated about 0.52, so the calculated values at S/D=3, obtained from interpolation the values of group reduction factor at S/D=2.5 and S/D=3.5, are close to the AASHTO recommendation.
Improved general slice method of limit equilibrium for slope stability analysis
Authors: Xiao Shiguo , Chen Tingjun
Published: September 2021

For traditional slice methods of limit equilibrium used to analyze slope stability, some hypothetical conditions on interslice force are generally introduced to solve the
problem. In order to reduce the defect theoretically due to the related hypothesis, more rigorous constraints of interslice force are completely considered in light of static equilibrium conditions and energy dissipation principle of the interface between two adjacent slices. Without hypothesis of interslice force, the slope stability analysis is transformed consistently into a non-linear programming problem to be solved. So, a generally improved solution of slice method of limit equilibrium to slope stability is put forward. In particular, influence of the dilation angle of soil on slope stability can be involved in the method. The proposed method can be utilized for any slopes with arbitrary slip surfaces.

Published: September 2021

To simulate heat transfer processes with phase transitions, the classical enthalpy model of Stefan is used, accompanied by phase transformations of the medium with absorption and release of latent heat of a change in the state of aggregation. The paper introduces a solution to the two-phase Stefan problem for a one-dimensional quasilinear second-order parabolic equation with discontinuous coefficients. A method for smearing the Dirac delta function using the smoothing of discontinuous coefficients by smooth functions is proposed. The method is based on the use of the integral of errors and the Gaussian normal distribution with an automated selection of the value of the interval of their smoothing by the desired function (temperature). The discontinuous coefficients are replaced by bounded smooth temperature functions. For the numerical solution, the finite difference method and the finite element method with an automated selection of the smearing and smoothing parameters for the coefficients at each time layer are used. The results of numerical calculations are compared with the solution of Stefan’s two-phase self-similar problem --- with a mathematical model of the formation of the ice cover of the reservoir. Numerical simulation of the thawing effect of installing additional piles on the existing pile field is carried out. The temperature on the day surface of the base of the structure is set with account for the amplitude of air temperature fluctuations, taken from the data of the Yakutsk meteorological station. The study presents the results of numerical calculations for concrete piles installed in the summer in large-diameter drilled wells using cement-sand mortars with a temperature of 25 °С. The distributions of soil temperature are obtained for different points in time

Authors: Bhargavi Y. , Sudhakar P. , Rajeswari V. Raja , Krishna T. Giridhara
Published: September 2021

Background: Heavy use of chemicals in agriculture has weakened the ecological base and caused the degradation of soil, water resources and quality of the food. The increasing cost and unavailability of fertilizers, growing ecological concern has forced us to try new methods of application of nutrients. Natural farming is the new method introduced as a holistic alternative to the present chemical input based agriculture. There has been increasing interest in the use of panchagavya, beejamrutha, jeevamrutha and other liquid organic formulations during the recent years. Therefore, there is a need to compare the efficiency of natural liquid organics and the regular chemical fertilizers. Hence, the present investigation is taken up with the aim to study the effect of different foliar spray of organics on growth of blackgram. Methods: A field experiment was conducted at the dryland farm, S.V. Agricultural College, Tirupati during Kharif, 2017 to study the effect of foliar sprays of different natural liquid organics on morphological and growth attributes of blackgram. Result: The results indicated that RDF (recommended dose of fertilizers) recorded significantly maximum plant height, leaf area, dry matter, seed yield and other yield attributes over the foliar spray of liquid organics. Results further revealed that significantly lower plant height, dry matter were recorded in the treatment receiving seed treatment with beejamrutha. No significant difference in terms of days to 50% flowering was observed among the treatments. Significantly higher emergence index was recorded in the treatments receiving seed treatment with beejamrutha and water. Integrated use of organics has recorded significantly more number of root nodules compared to other treatments. Jeevamrutha foliar spray recorded to be superior over panchagavya foliar spray which was attributed to the presence of micronutrients in jeevamrutha.
A Sustainable Agriculture: Organic Farming: A Review
Authors: Gugalia Gunmala
Published: September 2021

Agriculture is the backbone of India’s economy and agriculture employs more than 70% of the country’s people. With the continued use of fertilizers and their negative environmental repercussions, the farming community is becoming more aware of alternative agriculture systems, such as organic farming. Organic farming is a natural farming technique that meets society’s food and nutrition demands while not diminishing natural resources. Thus, by combining organic resources with high-yielding varieties and technologies, the country was able to enhance not only its food excess, but also its environmental pollution, pesticide toxicity and agricultural production sustainability. Organic farming also feeds crops with macronutrients and micronutrients, as well as improving the physical, chemical and biological qualities of the soil. In organic farming, pest and disease management alternatives rely mainly on preventive measures rather than curative treatments, which are based on environmentally safer management strategies. The priority has been placed on maintaining the ecosystem’s health, allowing plants to become resistant to insect pests and illnesses.

Authors: Aiswarya N. , Bhattiprolu S.L. , Reddy K. Bayyapu , Rao G. Rama
Published: September 2021

Background: Aspergillus niger and A. flavus cause rotting, damping-off, loss in germination and toxification of oil seeds. Aspergillus is a common mold in tropical and Sub-tropical countries and causes aflatoxin contamination. A. flavus and A. niger were responsible for storage rot of groundnut. In addition to storage rot, aflatoxin contamination also leads to adverse effects on consumer health. Therefore, present study was conducted to estimate the impact of both A. niger and A. flavus on seed quality parameters of groundnut. Methods: Effect of major seed borne fungi A.niger and A. flavus on seed quality characters of thirteen different genotypes of groundnut was observed in the present study. All the seedling quality characters were measured as per ISTA guidelines. Result: On an average A. niger caused 25.14, 25.18, 43.99, 26.20 and 44.75 per cent reduction in seed germination, seedling length, seedling vigour index I, seedling dry weight and seedling vigour index II, respectively, over the control whereas A. flavus caused average per cent reduction of 22.38, 24.23, 41.18, 23.92 and 40.95 in seed germination, seedling length, seedling vigour index I, seedling dry weight and seedling vigour index II, respectively, over the control.

Published: September 2021

Background: The microbiological quality of three vegetable crops (cabbages, carrots, lettuces) and their irrigation water from the lake system of the city of Yamoussoukro were studied. The pollution indicator used is Escherichia coli (E. coli), of the thermotolerant coliform family. Methods: During the period 2017-2019, in four dry and four wet seasons, a total of 744 water samples and 13392 vegetable samples were collected in five (5) lakes belonging to the lake system. The lakes were selected because of their position in the system. The E. coli loads were evaluated after isolation on a specific COMPASS ECC Agar and confirmed with Polymerase chain reaction (PCR) and the physicochemical parameters of the lakes, evaluated according to their respective ISO standards. Result: In irrigation waters, bacterial loads and physico-chemical parameters generally have evolved from the upstream lakes to those downstream of the lake system (from lake A to lake E). Values were higher during the rainy seasons. E. coli loads on vegetables were strongly correlated with those of irrigation water, especially in dry seasons. Spearman’s correlations revealed significant correlations between turbidity, DOC and bacterial loads. The risk of bacterial transmission between lake waters and surrounding vegetables is proven.

Authors: Lenka Biswajit , Baisakh Bhabendra , Dash Manasi , Lenka Devraj , Tripathy Swapan Kumar
Published: September 2021

Background: Mungbean is one of the most important legume crop with high nutritional value and is consumed in various forms in different parts of India. In order to meet its growing demand, there is a need to increase the yield through adoption of breeding approaches like heterosis breeding and breeding for high yielding varieties. This demands a critical study of the gene action involved in regulation of yield and yield attributing traits which can be achieved through generation mean analysis. Methods: In the present study, generation mean analysis was undertaken using five parameter model to estimate the nature and magnitude of gene action of yield and its component traits in six crosses of greengram. Result: Magnitude of dominance gene effect was reported to be higher than additive gene effect in most of the crosses. Either one or both the interaction components were found significant for all the traits besides number of branches per plant and hundred seed weight. It was evident from the study that the yield components could be improved by exploiting both additive and non-additive gene effects. The transgressive segregants thus produced will prompt the development of desirable high yielding genotypes.

Published: September 2021

This study aims to explore the training needs of parents for the future of children with intellectual disabilities (ID). The survey research method is used in this study. The questionnaire was used as a guide for parents, and then every chosen programme required by the parents was mentioned in the interview. Data analysis was carried out by categorising parental training needs into four domains of daily activities. The respondents were eight parents who needed training on the programmes of daily activities in order to train their children with ID at home. The findings show that those parents have still not been able to express their rights to convey their needs. Likewise, when they are invited to arrange the structure of the workout schedule at home, they still respond passively. The conclusion is that schools should start to explore the needs of daily activities programmes and develop learning programmes with parents.

Published: September 2021

Abstract
This study analyses the differences in knowledge, attitudes and multicultural skills of primary school students divided into two learning models, namely a multicultural-based learning model and a student team achievement division (STAD). This study used a quasi-experiment with two control classes and two experimental classes which were determined through random sampling. Prior to being randomised, an equivalence test was carried out to ensure all classes were equal. The experiment used was a post-test-only control group design with multicultural knowledge test instruments, multicultural attitude inventories and observation guidelines of multicultural skills. The results show that the multicultural knowledge, attitudes and skills of students who took multicultural-based learning model syntax were better than students who took the STAD type of cooperative learning model. The mean score of multicultural knowledge, multicultural attitudes and multicultural skills were 25.60, 147.95 and 121.05, respectively. Meanwhile, students who took the STAD learning model showed the mean score of multicultural knowledge, multicultural attitudes and multicultural skills were 22.88, 128.08 and 114.27, respectively. The syntax of a local genius-based learning model is easier for teachers and students to understand the learning steps. This makes learning more challenging, fun, values-based and meaningful for students’ real lives.

This article aims to identify the features of using metaphorical cards for the development of students’ social skills studying in university. The methods of research included testing and observation methods that allow to identify the levels of formation of students’ social intelligence structural components effectively; to determine the features of changes in the perception and control of their own and others' emotional and behavioral reactions, as well as the level of development of understanding of emotional expression. The study shows that the technology of using metaphorical cards is one of the leading ways of emotional-psychological, pedagogical and socio-moral influence on the development of structural components of students’ social intelligence. The effectiveness of working with metaphorical cards in developing communicative skills has been shown to be due to the mechanisms involved in different forms of working with metaphor.  It is considered that metaphorical cards allow projecting both negative emotional reactions arising in communication onto images, reducing the intensity of their experience, and projecting social images, acting as moral guidelines, onto real situations, using them as models of behavior.  It has been found that working with this educational technology helps to develop students' skills in understanding and managing their feelings, emotions and experiences. Practical relevance: The data obtained in this paper can be used in the study of problems related to educational psychology, personality psychology, social psychology and pedagogy.

Published: September 2021

Relevance: normal physical education and upbringing also contributes to the normal development of such qualities as memory, attention, high levels of stability, perception, observation, and mental performance. In physical education classes, the student learns rational and safe methods of life activity, rational actions, rules of personal and public hygiene, hardening, etc., which positively affects mental development, the process of mental education, and intelligence. The modern Russian school does not provide all the necessary conditions that would allow it to become a place for the formation of the health of schoolchildren. It is necessary to continue physical education after school, to form among children and adolescents the skills and abilities of a healthy lifestyle, a conscious and responsible attitude to the preservation and promotion of health. The main task is to develop and consolidate a conscious attitude to health, personal and public safety among children and adolescents for the entire life cycle. The reasons for the increased attention to the health of students are the following: insufficient motor activity, low level of knowledge, skills and abilities in the field of motor activity, as well as insufficient awareness of the formation of a healthy lifestyle of adolescents.

Banana weevil is a pest with a great impact on banana production in the world. The objective of this study was to evaluate the pathogenicity of the Kenyan entomopathogenic nematodes (EPNs) of genus Steinernema against the weevil Cosmopolites sordidus (Germar) under laboratory conditions. Adult weevils were trapped from banana fields in Maragua, Central Kenya and larvae extracted from the infested banana rhizomes. The adults were treated with three Kenyan EPNs Steinernema weiseri, Steinernema yirgalemense and the new Steinernema spp and with Steinernema carpocapsae ALL strain as a standard and plain distilled water as a control in five replicates. The treatments were 500ijs, 750ijs and 1000ijs per adult on petri dishes and 1000ijs, 3000ijs and 5000ijs per adult on pseudo-stems. The treatments for larvae in petri dishes were 300ijs, 400ijs and 500ijs. The adults were not susceptible to all the nematodes at all doses and preparations while larvae were highly susceptible to the four test EPNs at all concentrations. There was a significant difference at P<0.05 in the mortality of larvae between nematode Steinernema carpocapsae and Steinernema weiseri. A significant difference was observed between nematode Steinernema carpocapsae and Steinernema yirgalemense. There was also a significant difference between the new Steinernema spp and Steinernema weiseri and finally in the two nematodes the new Steinernema spp and Steinernema yirgalemense. All the test nematodes caused over 90 % larval mortality within 48 hours. The mean percent mortality of larva increased with nematode concentration for all the test nematodes. The results indicated that the four test EPNs significantly (P<0.05) caused high mortality within 24-48 hrs. The findings indicate that the banana weevil larvae are susceptible to the local entomopathogenic nematodes and potentially useful in the management of the banana weevil. It is however recommended that more research be conducted on the formulation and application technology to enhance their effectiveness in the field.

Introduction: Preeclampsia is a condition of hypertension that occurs after 20 weeks of gestation, followed by the detection of protein in the urine sample, and is one of the major causes of maternal mortality. It is categorized, based on time of gestation, into 2-stage are early and late-onset. One of the more accessible tools in diagnosing and also preventing preeclampsia is by its risk factors. The aim of this study was to observe the appearance of some of the risk factors in patients with late-onset preeclampsia and to allow a better approach in patients with said comorbidities.Methods: This was a descriptive observational study. The sample used was 35 patients diagnosed with late-onset preeclampsia in Dr. Soetomo General Hospital Surabaya from January to December 2016.Results: Among 35 patients diagnosed with late-onset preeclampsia, obesity (65.71%) appeared the most. Maternal age (37.15%) and primigravida (28.57%) appeared in second and third places. Chronic hypertension appeared only in 6 (17.14%) patients, whereas multiple pregnancies appeared in 3 (8.57%). Both patients with a history of previous preeclampsia and diabetes mellitus only appeared once (2.86%).Conclusion: Obesity has the most appearance in patients with late-onset preeclampsia, followed by maternal age and primigravida.

Introduction: Simvastatin is a primary pharmacological therapy for dyslipidemia (hypercholesterolemia). Virgin coconut oil (VCO) is a companion intake of statin drugs considered capable of lowering blood cholesterol levels. This study aimed to determine the combination effect of statin drug groups with VCO on total cholesterol.Methods: The stages of this study started with the adaptation process of animals, giving a high-fat diet (HFD), and treatment with simvastatin and VCO. The adaptation process was conducted where the experimental animals were fed pellets and drank clean water in a container. A HFD was given by mixing pork brains with distilled water with a ratio of 1:3 as much as 2 ml per day for 21 days. In simvastatin and VCO treatment for 7 days, the experimental animals were divided into 4 groups; group I was given aquades, group II was given VCO, group III was given simvastatin, and group IV was given simvastatin and VCO. The total cholesterol levels in the blood of albino rats were examined by employing a BS-300 Chemistry Analyzer through a spectrophotometric method. The total cholesterol levels data obtained were then examined for normality (Shapiro-Wilk test) and analyzed parametrically by utilizing One-way ANOVA.Results: The average total cholesterol level in the negative control group (being given a standard diet) was 45.57 mg/dL. The averages of blood total cholesterol levels were 47.28 mg/dL, 45.00 mg/dL, 46.85 mg/dL, 41.42 mg/dL, and 44.28 mg/dL in the positive control group (given an HFD), in the treatment group I, in the treatment group II, in the treatment group III, and in the treatment group IV, respectively. There were no significant distinctions in the statistical test on decreasing blood total cholesterol among the negative control group, positive controls I, II, III, and IV.Conclusion: Combination of simvastatin and VCO tends to reduce the total cholesterol level in albino rats. This is better than just giving VCO simvastatin alone.

Evaluación del espacio público para un envejecimiento activo en España: estudio de caso en las 3 ciudades más pobladas = Evaluation of public space for active ageing in Spain: study case of the 3 largest cities
Authors: Pozo Menéndez Elisa
Published: September 2021

ResumenEl presente trabajo aborda el reto del envejecimiento activo desde la perspectiva del diseño urbano: ¿son los espacios públicos de las ciudades españolas “amigables” para las personas mayores? Se ha realizado una caracterización de las necesidades específicas del adulto mayor y los elementos de diseño del espacio público que deberían tenerse en cuenta en proyectos de renovación urbana. Esta caracterización, junto con una revisión de guías y documentos técnicos, ha dado como resultado la selección de 25 elementos para la evaluación de un caso de estudio en el casco urbano de la ciudad consolidada de las 3 ciudades españolas más pobladas. Los resultados muestran un mínimo de habitabilidad y accesibilidad de los espacios públicos, pero un déficit en los parámetros de calidad para favorecer entornos “amigables” con las personas mayores, como zonas estanciales con bancos ergonómicos, elementos de apoyo cada cierta distancia o señalética accesible para orientarse en las calles.AbstractThis study addresses active ageing from the urban perspective: are public spaces in Spanish cities age-friendly? A characterization of the older adult has been done identifying the elements of the public space that should be considered in projects of urban renovation. From this characterization, as well as a review of guides and technical documents, 25 elements have been proposed in order to evaluate one study case in the urban city centre of the 3 largest cities in Spain. Results show a minimum quality of habitability and accessibility in the built environment. However, there is a lack of quality parameters in order to promote healthy and age-friendly urban environments, such as ergonomic benches in places to stay, minimum distance between supports or signals to support way-finding in streets.
Análisis de la Política de TransporteyAccesibilidad Universalen Ecuador = Analysis of the Transport Policy and Universal Accessibility in Ecuador
Authors: Chacón Martínez Katherine M.
Published: September 2021

ResumenLas políticas de transporte y accesibilidad universal en Ecuador han evolucionado desde el reconocimiento de los derechos de las personas con discapacidad en la Ley Orgánica de Discapacidades, de 2012. Desde esa fecha, los planes, programas y proyectos en el transporte han incentivado a la generación de una movilidad accesible universalmente. Sin embargo, las personas con discapacidad aún no pueden movilizarse de manera autónoma, cómoda y segura. Este estudio se basa en reconocer los principales problemas que perpetúan esta vulneración de derechos e identificar los ámbitos de inclusión, accesibilidad universal y movilidad urbana terrestre que garantizan el cumplimiento efectivo en relación con los instrumentos legales nacionales e internacionales, especialmente con la Convención sobre los Derechos de las Personas con Discapacidad. El resultado muestra que los esfuerzos realizados aún no son suficientes y se necesita una homologación de la perspectiva de accesibilidad universal en la política pública de transporte ecuatoriana.AbstractTransportation and universal accessibility policies in Ecuador have evolved since the recognition of the rights of people with disabilities in the Organic Disability Law of 2012. Since that date, transportation plans, programs and projects have encouraged the generation of universally accessible mobility. However, people with disabilities are still unable to mobilize autonomously, comfortably and safely. This study is based on recognizing the main problems that perpetuate this violation of rights and identifying the areas of inclusion, universal accessibility and urban land mobility that follow effective compliance in relation to national and international legal instruments, especially the Convention on the Rights of Persons with Disabilities. The result shows that the efforts made are still not enough and a homologation of the universal accessibility perspective is needed in Ecuadorian public transport policy.
