LAS INASISTENCIAS DE LOS ESTUDIANTES: LA ESCUELA SECUNDARIA EN CUESTIÓN
Authors: Martino Andrea
Published: October 2020

En este artículo (1) se presentan avances de la investigación que se viene realizando sobre el ausentismo de los estudiantes en la escuela secundaria. Se trata de un estudio de caso en una escuela de gestión estatal ubicada en una localidad aledaña a Córdoba Capital. Iniciamos el texto presentando la problemática de las inasistencias escolares como un analizador de las tensiones entre las definiciones de la política pública que extienden y democratizan el tiempo escolar y las dificultades para hacer que ese tiempo se traduzca en aprendizajes efectivos. Partimos de considerar al ausentismo estudiantil como discontinuidad, interrupción y disminución del tiempo para aprender y que en su producción hay múltiples razones y condiciones, por lo cual es necesario pensar en formas de ausentismo. El trabajo de campo permite reconocer las voces de aquellos que suelen estar ausentes en las escuelas, y acercarnos a los obstáculos y condiciones que dificultan efectivamente su presencia en la escuela; también a los sentidos que van construyendo en un tiempo que es para aprender, en coincidencia o no, con sus otros tiempos vitales. Las reflexiones finales invitan a preguntarse y pensar alternativas acerca de las ausencias de los estudiantes desde apuestas más integrales de trabajo con los jóvenes.
LO POLÍTICO EN EL CURRICULUM DEL SIGLO XXI
Authors: Morelli Silvia
Published: October 2020

Este ensayo propone una reflexión sobre el curriculum y su relación con lo político y la democracia en los actuales escenarios sociales. Su análisis se enmarca en la Filosofía Política de Rancière, como también de Mouffe, elaborando un texto que permite considerar la naturaleza política del campo del curriculum. Se parte desde 1989, tras la instalación del consenso neoliberal en educación, y específicamente en el curriculum. Destaca posicionamientos acerca del consenso, tomados de Sander y Habermas, contrarrestándolos con Lyotard y Laclau. Propone la vuelta a lo político desde perspectivas posmodernas y recupera la emancipación como desafío para repensar las tareas curriculares del presente.
NUEVOS OBJETOS Y NUEVAS TÉCNICAS PARA LA ENSEÑANZA DE LA MATEMÁTICA
Authors: Sánchez Luján Bertha Ivonne , Camacho Ríos Alberto
Published: October 2020

En este artículo se presenta un estudio orientado hacia la transposición de un concepto apraxeologías matemáticas. El concepto se desprende de tecnologías externas a las praxeologías, destacándose así un episodio de confrontación de conocimientos prácticos que ocurre al intentar legitimar las diferentes técnicas que de esa inmersión se desprenden. De esa confrontación resultan ambigüedades y rupturas epistemológicas que dan lugar para incorporar tecnologías prácticas para la validación de las técnicas, puesto que el modelo praxeológico no responde al nivel de empirismo resultado de la actividad. El objetivo principal es poner en evidencia la falta de justificación de técnicas externas a la práctica matemática que se transponen para resolver ciertas tareas T y, además, cómo esa carencia de justificación hace necesarios otros argumentos tecnológicos en la Teoría Antropológica de lo Didáctico para su propia justificación.

Published: October 2020

El presente artículo expone los resultados de una investigación que toma como objeto de estudio las políticas para el andamiaje de trayectorias escolares en la escuela secundaria en Latinoamérica. La investigación se basó en un estudio basado en una lógica cualitativa, realizada con el Método Comparativo Constante. El trabajo de campo que se considera en este artículo incluyó una selección de instituciones educativas que se ubican en contextos de alta vulnerabilidad social en cinco países de la región: Bolivia, Chile, Perú, Paraguay y Uruguay. Se realizó un relevamiento de las problemáticas vinculadas a las trayectorias escolares de los estudiantes de nivel medio que viven en contextos de vulnerabilidad y un mapeo y análisis de las intervenciones que se realizan desde la política educativa para el andamiaje de dichas trayectorias. Este artículo incluye, además de la presentación de algunos elementos teóricos y metodológicos que guiaron la investigación, una breve contextualización histórica de las políticas socioeducativas en la región y una presentación de algunas tendencias en relación al análisis de diferentes casos de países. Se analizan las estrategias mapeadas en particular considerando dos pares de categorías que permiten analizar las lógicas de intervención desarrolladas: focalización-universalismo e intervención-autonomía.
‘CINECONVERSAS’ – CRIANDO CURRÍCULOS COM FILMES DE MIGRAÇÃO
Authors: Ferreira Machado Marcelo , Morais María , Toja Noale
Published: October 2020

Ao percebermos a potência dos usos dos filmes e da produção audiovisual como dispositivos fomentadores de conversas, catalisadores de ideias, sensações, sentimentos, fomos tecendo ‘conhecimentosignificações’ e pudemos agregar outros valores para a pesquisa, como a ludicidade, a criatividade e o compartilhamento.Trazer o tema ‘migração’, por meio de filmes, questão urgente nos tempos atuais, nos aproxima desses acontecimentos com sensibilidade, incorporando-os às nossas realidades, já que compreendemos esses processos migratórios como as relações vividas por cada um de nós e pelos nossos familiares, seja vindo de outros países, vindo de outros estados, cidades, bairros, diferentes territórios, guetos, facções, culturas, sentimentos. Essas sensações podem nos aproximar de realidades criadas nas diferentes redes educativas que formamos e que nos formam. Ao tratar de migração ou refúgio com Cineconversas, metodologia desenvolvida no grupo de pesquisa, lidamos com artefatos e componentes curriculares, criamos um caminho de aproximação entre limites e fronteiras a que estamos submetidos o tempo todo como migrantes ou estrangeiros em diferentes situações da vida cotidiana.
LAS INICIATIVAS EN PRIMERA INFANCIA BAJO ANÁLISIS: ACTORES, RACIONALIDADES Y SENTIDOS EN TORNO A LA CRIANZA Y EL CUIDADO INFANTIL
Authors: Santillán Laura
Published: October 2020

En este artículo el objetivo es abordar las premisas que se ponen en juego en torno a los niños y las niñas que transitan la primera edad de la vida entre cero a cinco años. Ahondaremos en el análisis de fuentes documentales y legislativas generadas por organismos estatales y no gubernamentales que participan del campo de intervención en Primera infancia (1). Junto con el interés por los actores que intervienen, nos preguntamos por las racionalidades y saberes que construyen. Es nuestra hipótesis que, desde las voces que hegemonizan el campo de intervención, las premisas sobre la primera infancia fomentan un particular lenguaje del cuidado, la crianza y educación infantil. Este lenguaje se sustenta en el valor neutro de la ciencia, pero sin embargo devela sentidos morales y políticos tendientes a la modelación de hábitos en las familias. El análisis documental se inscribe dentro del trabajo de campo antropológico que venimos llevando adelante en el Gran Buenos Aires, Argentina

EL SISTEMA DE FORMACIÓN DOCENTE Y LA PRODUCCIÓN, RELEVANCIA, VALIDACIÓN Y LEGITIMACIÓN DEL CONOCIMIENTO: ALGUNAS DIMENSIONES PARA ABORDAR UNA AGENDA AÚN PENDIENTE
Authors: Ricci Cristina Rafaela
Published: October 2020

Analizar cómo, dónde, quiénes y a través de qué procedimientos se valida, legitima y difunde el conocimiento producido por los Institutos de Educación Superior (IES), requiere pensar más allá de los contextos clásicos de descubrimiento y justificación e, incluso, ir más allá de la concepción moderna de ciencia. En este sentido, sostengo que los planteos epistemológicos y metodológicos de la concepción heredada de la modernidad, no son los más aptos para otorgar estatus científico a las producciones de los IES.Surgen así, por lo menos dos dimensiones a tener en cuenta al momento de abordar algunas preguntas centrales que, el Sistema de Formación Docente debe asumir como parte de su agenda: una dimensión político-educativa y otra espistemológico-metodológica. Entonces, ¿Desde qué perspectivas  epistemológicas y metodológicas hay que analizar las investigaciones que se desarrollan en los IES? ¿Por qué hasta el presente los conocimientos y saberes producidos en los Institutos Superiores de Formación Docente (ISFD) no son reconocidos como tales? La validación, legitimación y relevancia del conocimiento producido por los IES/ISFD, ¿Cómo, quiénes y para qué se establecen? Reflexionar sobre esto puede contribuir a que la producción de saberes y conocimiento se constituya en un rasgo identitario del Sistema de Formación Docente.

Authors: Hou Junming , Yang Yong , Zhu Hongjie , Hu Weixue
Published: October 2020

Castor is an important oil crop. Impact damage is critical in the process of castor capsule shelling, directly affecting the shelling effect of castor seeds. An experiment was taken to investigate it. To study the damage degree of castor capsule under the impact, water content, impact height, and impact angle were taken as test factors, and the maximum impact force and normal deformation were taken as test indexes. The combination optimization was carried out through the multi-objective genetic algorithm. The results show that the impact height has a significant effect on the maximum deformation (p<=0.01), and the water content and impact angle have a significant impact on the impact force (p<=0.05). The height and angle have a significant impact on the deformation (p<=0.01), and the water content has a significant impact on the deformation (p<=0.05).
Caractérisation de l’activité de butinage du pollen par l’abeille mellifère au Centre-est de la Côte d’Ivoire : intérêt pour l’apiculture
Authors: COULIBALY Siendou , KOUDEGNAN Comlan Mawussi , DRO Bernadin , SALLA Moreto , OUATTARA Djakalia
Published: October 2020

La maîtrise de l’activité de butinage des plantes par les abeilles est nécessaire pour mieux orienter les apiculteurs en vue d’une meilleure productivité apicole. La présente étude vise à contribuer à la maîtrise de cette activité. L’acquisition des données s’est faite à travers des observations mensuelles pendant une année. Les résultats révèlent que les abeilles butinent les fleurs pendant toute la journée et tous les mois de l’année. Toutefois, l’activité globale de butinage est beaucoup plus accentuée entre 6 heures et 11 heures et entre décembre et mai. Cependant, la récolte du pollen particulièrement, a lieu seulement dans la matinée, de 6 heures à 13 heures, avec une intensification entre 7 heures et 9 heures où elle occupe plus du quart des abeilles butineuses. La période allant de juillet à novembre est aussi largement consacrée à la collecte du pollen. Pour une récolte rationnelle du pollen (en tant que produit de la ruche) à l’aide de trappes, la période idéale serait donc entre 6 heures et 11 heures. Characterization of pollen foraging activity by honey bees in central eastern Côte d’Ivoire: interest in beekeeping ABSTRACT This study is carried out to control plant foraging activity by honey bees to guide beekeepers towards better productivity. The data were collected through monthly observations over a year. The results showed that bees forage for flowers throughout the day and every month of the year. However, overall foraging activity is much higher between 6 a.m. and 11 a.m. and between December and May. However, pollen collection, in particular, takes place only in the morning, from 6 a.m. to 1 p.m., with an intensification between 7 a.m. and 9 a.m. when it occupies more than a quarter of the foraging bees. The period from July to November is also largely devoted to pollen collection. For a rational harvesting of pollen (as a product of the hive) with the help of traps, the ideal period would therefore be between 6 a.m. and 11 a.m.

Authors: Berdnikov О. М. , Volkohon V. V. , Potapenko L. V. , Kozar S. F.
Published: October 2020

Objective. Determine the parameters of uptake of organic matter and biogenic elements withby-products of crops under the use of mineral and green-manure-mineral fertilization systems andmicrobial preparations. Methods. Field experiment, agrochemical, balance, statistical. Results.Under the conditions of short crop rotation “winter wheat – intermediate green manure – corn forgrain – soybean – winter wheat”, the influence of microbial preparations Biogran (on the basis ofnitrogen-fixing bacterium Azospirillum brasilense 410 and physiologically active substances) forcorn and Nitro-Legu (on the basis of complex of diazotrophs Bradyrhizobium japonicum, Azospirillum brasilense and polysaccharide) for soybeans on crop yields, uptake of by-products in the soil,balance of nitrogen, phosphorus and potassium depending on fertilization systems. Under exposureto biopreparations, uptake of corn by-product in the soil increased by 1.41–2.12 t/ha, soybeans —by 0.51–0.71 t/ha of dry matter, depending on the agrarian backgrounds, which, taking into account the humification factors, can provide soil replenishment with humus at the level of 0.31 to0.47 t/ha and 0.12–0.17 t/ha, respectively. Nitrogen and phosphorus balances, as well as their intensity under the mineral fertilization system were positive. Green-manure-mineral fertilization system and pre-sowing bacterization of seeds helped to improve the parameters compared to the mineral fertilization system. Potassium balance was slightly deficient (–16.2 to 20.4 kg/ha at a balanceintensity of 78–80 %) under exposure to the mineral fertilization system and positive under exposure to green-manure-mineral system. Microbial preparations helped to improve parameters. Additional uptake of the biogenic element compounds in the soil provided an increase in the yield ofwinter wheat. According to the results of the evaluation of the balance of the key nutrients, a satisfactory ecological balance was created in the short crop rotation under exposure to green-manuremineral fertilization system and pre-sowing bacterization of corn and soybean seeds. Conclusion. Upon evaluation of the efficacy of microbial preparations in crop cultivation technologies, theparameters of uptake of organic matter and biogenic element compounds with by-products in the arable soil layer should be taken into account along with their direct effect on yield formation andproduct quality.
EFFICACY OF MICROBIAL PREPARATIONS IN GROWING SPRING WHEAT DEPENDING ON THE FERTILIZATION BACKGROUND
Authors: Vlasiuk О. S.
Published: October 2020

Objective. Develop a fertilization system for spring wheat based on the use of effective compositions of nitrogen-fixing and phosphorus-mobilizing bacteria, which will help to reduce the spreadof disease and increase the productivity of agrocenoses. Methods. Field, measuring- and weightbased, calculation, mathematical and statistical. Results. The influence of mineral fertilizers, aftereffects of green manure, treatment of seeds with biopreparations and spraying of crops with Biocomplex-BTU on the parameters of productivity and exposure of spring wheat to powdery mildewhas been shown. It was found that pre-sowing bacterization of seeds increases yields by 3.3–12.4 %, depending on the biopreparations and fertilization background. Under the action of mineral fertilizers both separately and against the background of the after-effect of green manure, theyield increased by 31.7–41.2 %, compared with the variant without fertilizers and without inoculation. Treatment of spring wheat leaf with Biocomplex-BTU increased yield by 3.6–7.2 %, dependingon fertilizer and pre-sowing bacterization of seeds. Inoculation of seeds and treatment of crops withbiopreparations results in increase in the number and length of productive stems and grains inthe ear, although the use of fertilizers increases these parameters more significantly. Conclusion. Treatment of wheat seeds with bacterial preparations has a higher percentage efficiency in areas without fertilizers compared with fertilized ones, as well as in less favourable years for thegrowth of spring cereals, compared with more favourable. Seed inoculation with Polimiksobakterynin combination with the treatment of crops with Biocomplex-BTU, which, depending on the fertilizer, increases the crop yield by 0.54 to 0.73 t/ha, is the most effective. Crop treatment with Biocomplex-BTU significantly reduces exposure to powdery mildew.
EXPERIMENTAL JUSTIFICATION OF PROSPECTS OF USING THE ENTOMOPATHOGENIC PREPARATION BOVERYN FOR THE PROTECTION OF PINETUM
Authors: Drozda V. F. , Karpovich M. S.
Published: October 2020

Objective. Study the possibility and feasibility of using the entomopathogenic fungal preparation Boveryn to protect pinetum from damage by pine silkworms. Methods. Field (collection of vegetation samples on the soil surface from trunk circles of model trees; collection of worms from treecrowns); laboratory (species identification, physiological monitoring). At the same time, physiologically defective samples with signs of diseases and also damaged with by worm entomophages wereremoved. They were distributed according to known characteristics, namely: size of the main capsule and age. The selected materials were placed in gauze cages with common pine branches.Worms of three species of seedworms were selected accordingly, and they were diapaused on treetrunks and in the soil. During the studies, the entomopathogenic fungal preparation Boveryn wasused with a titre of 6 billion spores/g and at a concentration of 0.5 %. Results. It was found that thelevel of entomocidal action of Boveryn against worms of different ages is determined by the speciesand age susceptibility of phytophages, as well as temperature. Accounting of the changes in parameters of the death of worms of the pine silkworm of the third generation over time shows that the population is quite vulnerable to Beauveria bassiana (Bals.) Vuill — the active substance in Boveryn. Actually, the experiment confirmed the feasibility of adding suspensions of the preparation inplaces of diapause of phytophages. At an air temperature in the range of 12–17 °C, at least 50 % ofthe pest population dies in only 9.4–12.5 days. When the temperature increases, the time of deathof worms is reduced. The digital mortality characteristics of pine silkworm worms in the fourth andfifth generations (populations of worms that feed on tree crowns) are quite informative. Conclusion. It is feasible to use Boveryn with appropriate procedure (spraying, etc.) in the areas of extensive spread of pine silkworm to ensure control of the number of pests.

This research paper discuss about the friction behavior of Al-12Si-xB4C composites prepared through powder metallurgy method by varying the weight percentage of reinforcement (x = 2, 4, 6, 8, and 10) content. The samples were prepared by using die and punch assembly and the lubricant used to eject the sample from the die was molybdenum disulfide. The compaction was done by using compression testing machine by applying a pressure of 800MPa. The dry sliding friction behavior of the sample was conducted on Pin-on-Disc machine and the experimental values of friction were calibrated. Taguchi design experiment was done by applying L25 orthogonal array for 3 factors at 5 levels for the response parameter coefficient of friction. Analysis of Variance demonstrated by Mean and S/N ratio table for coefficient of friction was discussed and from the table it can be seen that the reinforcement plays a main role, when the compared with load and sliding distance. The normal probability plot shows that the residuals falls near to the red line, it indicate that the error values were less in the model.

In our country every year some of the regions are facing with heavy rainfall and the other regions are facing with lack of rain. As a part heavy rainfall regions are suffered with floods and the huge amount of the water is run off into the sea. At the same time the less rain fall regions are suffered with droughts and famines. To avoid all such type of problems NWDA (National Water Development authority) kept a proposal of interlinking of rivers. While the rivers are linking with one another there is some disturbance will be occur for the environment i.e, reserve forests, hilly terrains and human habitats will be affected. To minimize the degradation we suggested some diversions for the proposed (PENNAR TO CAUVERY) link canal. These suggestions are made through the remote sensing and verified through a mathematical tool. In identifying the diversions for a canal there is a multiple diversions have to face. From the multiple diversions the best alternative path was identified by using of TOPSIS (technique for order preference by similarity to ideal solution) method which gives the strength to the remote sensing assessment. Here we made eleven suggestions for the alignment. Through these modifications 25 villages and 5 tribal villages are benefitted. 39 sq.km. Reserve forest is going to be protected. 58 sq.km. hilly terrain is also benefitted without getting damage.

Implementing SWOT Analysis in Engineering Education in Africa
Authors:   Mangosuthu University of Technology, Durban, South Africa., Fomunyam* Dr. Kehdinga George
Published: October 2020

A research on engineering by the Royal Academy of engineering (RAE) in the year 2012 revealed that engineering has the capacity for economic and social development in various countries of the world. With the numerous opportunities and strength in engineering education comes its weaknesses and threats which necessitates a look at SWOT analysis. SWOT analysis is a tool for strategic planning and strategic management in organizations. This study analyzed implementation of SWOT analysis in engineering education in Africa and SWOT analysis as a concept was examined. Findings from the study revealed that SWOT analysis evolved in the 1960s. Though with improvement in knowledge and time, it has been superseded by other tools such as resource-based planning and competency-based planning. It is a tool for strategic planning and strategic management. There is no general convention or method for implementing SWOT analysis generally. Understanding the context and prevailing conditions is key in determining the appropriate dimension to exploring SWOT analysis in engineering education in Africa. The study therefore recommends that more effort be intensified on advancing the strengths and opportunities engineering education has while also overcoming its threats and weaknesses.
Political Capital as the Hallmark of Engineering Education in Africa
Authors:   Mangosuthu University of Technology, Durban, South Africa, Fomunyam Dr. Kehdinga George
Published: October 2020

When a political actor or a government delivers on its promises, whether on provision of infrastructure or favourable policies, it automatically earns political capital as a reward and as a bargaining chip for future purposes. This study explores the intricacies of political capital and its impacton engineering education in Africa. It examines political leverage as a key indicator of a functioning education system and the effect of engineering education on politics in turn. Political capital enables political players use their connections to secure compliance especially in terms of advocating for and pushing forward policies that ensure growth in engineering education, which is an essential part of overhauling and restructuring the African economy. The study also suggests yet-to-be-explored routes that could further advance engineering education in Africa.

Published: October 2020

Managing plastic waste is a global problem that threatens the safety of our environment due to its high generation and non-biodegradability. However, the PWs must be carefully managed in order to reduce the pollution involved in incineration and disposal of landfills. Plastic waste can be recycled into fresh, functional construction materials. In this study, the shredded PET waste aggregate from the recycling centre was heated to 230 0C and used as a binder for the full substitution of cement with river sand for the manufacture of floor tiles. The properties of the aggregate materials and floor tiles (including their distribution of particle size, silt, clay and dust content, relative density, water absorption, porosity, flexural and compressive strength) were evaluated on various PET wastes: sand mixing ratio, 100%, 90%, 70%, 50% and 30%. Results showed that the tiles formed by 30 per cent PET and 70 per cent River Sand (3:7) had a higher density, flexural and compressive strength than the other percentages of the mixture. The compressive strength of the tiles produced with 30% PET waste composition was higher than that of cement (with 28 days of curing) for residential buildings. Based on the strength, low water absorption and eco-friendliness, PET waste can be used for floor tiles with 30% PET substitution based on the test results.

Income inequality is crucial issue in the Malaysian economy. This issue has a great impact especially on the B40 group income household because of the rising cost of living today. Therefore, modelling of income data is done to look at income pattern of B40 group in Malaysia. Household income data for Malaysia in year 2007, 2009, 2012, 2014 and 2016 have been used in this study. The income distribution used in this study is a two-parameter distribution of Weibull, Log Normal, Fisk and Gamma. This study uses only two parametric distributions to suit the income data because the simplest model is better than the complex model. The best distribution selection is performed with the fitting of statistical distribution through maximum likelihood estimation (MLE) method. Goodness of fit test has been done to model B40 household income data. The best model for each year used to predict the average income in the future by using regression method. Weibull distribution is the best model for B40 household income data. The study also shows that the average income of the B40 group in the future will increase. Therefore, this study was conducted to assist B40 group to be more sensitive to the Malaysian economy and plan their income wisely.

Hence the present investigation is focused on the design of a batch stirred tank reactor with two different impellers to produce biodiesel with the use of rubber seed oil. Further an experiment was conducted in optimizing the process parameters using Taguchi methodology. The Taguchi methodology is mainly focused on the enhancement of the product produced and this is the most precise method used. The best combinations were obtained through the L9 orthogonal array. The reactor specifications were fixed to be 7.5cm. height, 7.5cm diameter, 2.5 cm agitator diameter, 0.625cm baffle thickness with 2.5cm as distance between bottom of the tank and impeller. Two impellers with 0.5cm. Width, 0.625cm length and others with 1.1cm length were used to test the individual performance towards yield. The optimum conditions obtained were found to be Impeller type-Straight blade impeller, Temperature- 65ºC, Time - 45min, Reactant ratio - 1:6, Catalyst amount- 22.46% (mol% of Oil), and Impeller Speed- 500rpm with the yield of 88 % . Hence BSTR reactors could be scaled up for translational research studies too.

Suspension systems are designed for the increase in comfort and stability in vehicles while driving. Parameter changes in these systems affect overall performance. Researchers are continuously working on the performance enhancement of suspension systems by designing dampers of variable damping coefficient. In this research work a quarter car model suspension system was developed to demonstrate experimentally the influence of changing the damping coefficient, the stiffness, and the loading level to fully understand the allowable combination of parameters for a smoother ride. A variety of different test scenarios are implemented to the system to observe the variations in damping ratio. The damping ratio of the system found to be dependent on the design of the opening mechanism.The valve opening methods can give different results with the same parameters.

In the present Era escalation of multi-storey high rise building is very common because of rapid urbanization in the entire world also innovation in the field of Engineering, science and Technology. Also Engineers have sophisticated designing software. As height of the building increases building response to the wind and seismic load increases. It means that forces and displacement of the structure is directly proportional to the height of the structure. Many research studiesare going on to reduce the structural instability due to high speed winds and earthquakes. During the earthquake the multi-storey high rise structures are failed to resist the seismic loads and it become the catastrophic disaster for human life’s and for the country. It is most important that structure should be able to withstand against external excitation forces. This can be achieved by building structure more flexible.During the time of earthquake multi-storey structures are swing and large deformation is occurred and vibrations are transferred in the structure through the ground which causes instability in structure. Thus the use of damper is resists lateral forces (wind load, earthquake load) and providing stability to the structure. Dampers are the mechanical devices which dissipate energy which is facilitate in multi-storey structure to reduce the displacement, buckling of beams and columns and increases the structural stiffness. There is lot of various types of dampers are used in RC multi-storey building. This study deals with performance and selection of suitable type of damper which will be more resistant to earthquake for the selected multi-storey building and different seismic parameters like time period, story stiffness, story displacement, story drift and base shear are checked out. In this study seismic behavior of multi-story RCC building with various types of dampers like fluid viscous damper, friction damper and tuned mass damper is carried out.

Construction projects suffer from diverse uncertainties that hinder the key objectives’ achievement. These uncertainties represent risks that may appear through the project life cycle. This paper introduces a quantitative model to estimate and rank risks dynamically during the risk planning phase. Such ranking would help decision-makers appropriately respond to and/or control construction risks. The model provides proper risk contingency reserves for both project time and cost that meet decision-makers' selected confidence levels using Monte Carlo Simulation (MCS). In order to quantify the project uncertainty, severities of residual risks are determined and allocated at the project's activities-level using a planning/scheduling spreadsheet model and a MCS tool suitable for spreadsheets. The model is able to calculate the contribution of each risk from the determined contingency at both the project level for both the time and cost at the decision-maker confidence level.The model represents a direct implementation for a Risk Planning Contingency Model (RPCM); which involves four modules as follows: (1) Risk Register (RR), (2) Risk Allocator (RA), (3) Risk Simulator (RS), and (4) Contingency Calculator (CC). These modules are hosted in a critical path model scheduling spreadsheet to facilitate risk management. In addition, a simulation engine add-in is used for analyzing the probability distribution for the project time and cost outcomes. In order to verify the proposed model, the process and analysis have been applied to a case study project. The results show that the RPCM is capable to rank and estimate the residual risks in an easy, fast, and effective way.

The foundation of the lightweight structures is commonly in unsaturated state conditions because located above the ground-water table. The matric suction governs the hydro-mechanical behaviour of unsaturated soils. Soil suction estimation is challenging both in the field and lab. The indirect and direct techniques are utilized to measure the soil suction. Several types of equipment utilized to measure the soil suction have been developed with innovative technology. However, there are constraints on reliability, suction range estimation, application, etc. The primary objective of this study is to review, describe the working principle, report limits, and benefits of various techniques utilized to measure the soil suction and select the cost-effective. A comparative study on direct and indirect technique of soil suction estimation is conducted base on recent literature, with a focus on suction range, procedure, type of suction, processing time, and application (lab/field). The apparatus utilized to measure directly or indirectly the matric suction found in the literature displays the highest range in the order of 1500 kPa except for the filter paper. The thermocouple psychrometer and the transistor psychrometer can measure a maximal total suction of 8000 kPa. The chilled-mirror hygrometer can measure a maximal total suction of 30000 kPa in the laboratory. The filter paper technique and the chilled-mirror hygrometer are cost-effective techniques. However, the filter paper technique is likely the easiest and low-cost technique to measure the matric suction and total suction for the full range with extreme care in the test procedure both in the field and lab.

Nowadays, with an increased supply for service quality multimedia communication over MANETs. Increased bandwidth, increased data rate, decreased latency, and increased ad-hoc network performance are the key objectives of using the queuing model. In this paper, when considering queuing delay and server use, a queuing model is created to analyze the cellular network in terms of video, audio, and text content. In a tailored discrete-event environment, this framework helps us to conduct functional testing of suggested algorithms. Servers service both types of data packets inserted into the network without long queues in the simulation performance. A SimEvents-based architecture is implemented at the concrete level for traffic simulation. This structure explores the effect of traffic generation on the system's queuing delay and server utilization.

The simulation of complex systems increasingly requires the collaboration of related researchers: domain experts (e.g. experts in the studied domains), modellers and computer scientists. However, the actual methods of modelling and simulation allow to produce only simulators that are used locally and considered as standalone applications. This kind of simulator hampers the exchange of these researchers; especially for the domain experts who are usually geographical distributed and not expert at using support tools. Our research focus on the collaboration among these scientists where many issues need to be addressed, e.g. scenario definition, parameter manipulation and results analysis. In this paper, we thus present a method, namely DeCoSim, supporting the collaboration among different scientists in the simulation of complex systems. A case study related to the modelling and simulation of Intra-Urban Daily Rhythms is presented to show the efficiency of the proposed method.
