Notas para una filosofía de la educación intercultural abiayalense.

La educación intercultural se convierte en un imperativo global. Hasta las empresas multinacionales hablan de la necesidad de contar con personal capacitado interculturalmente. El continente Abia Yala no está ajeno a esta atmósfera. Por su parte, la filosofía, como cuestionadora permanente de todo statu quo en aras a crear las condiciones para hacer realidad una humanización solidaria más plena, debe hacerse cargo de esa función crítica, no siempre cómoda, con el fin de que lo reconocido como necesario y que va configurando una atmósfera mundial en las propuestas educativas, mantenga su creativa vigilia frente a las instrumentaciones que pueden desvirtuar el propósito educativo intercultural. La filosofía debe realizar el primer cuestionamiento frente a sí misma y sus modos de educar filosóficamente, puesto que el eurocentrismo interiorizado de la educación filosófica académica asegura la hegemonía cultural gnoseológica en la que hace pie el monótono ritmo del tiempo y del espacio sancionado por el mercado como única posibilidad cultural pedagógica y civilizatoria mundial. La filosofía intercultural no se queda en sí misma, cómplice del proyecto mercantil neoliberal; debe formular sus propuestas para mantener la guardia a fin de que la educación intercultural no se convierta en fachada que esconde su asimilación sistémica deshumanizante y depredadora de culturas, del mismo modo que el mercado procede con el medio ambiente, pues con ello no pasaría de una nueva herramienta neocolonial depredadora de la vida natural y humana

En los límites de la frontera oeste: etnografía histórica de los puestos indígenas del SPI en Mato Grosso (Brasil)

El SPI —“Serviço de Proteção aos Índios”, creado para operar junto a los indígenas en Brasil— fue fundamental para mediar en los conflictos existentes entre grupos indígenas y no indígenas y, de esa forma, permitir el poblamiento colonizador al inicio del siglo XX, a partir de 1910. En tal contexto histórico-social, el objetivo del presente artículo es esbozar una etnografía histórica de los frentes de contacto del SPI y de los frentes de expansión con los pueblos indígenas en el Estado de Mato Grosso, frontera oeste, con enfasis en las relaciones producidas: conflictos y enfrentamientos generados, dinámicas de movimiento territorial, negociaciones, retrocesos y aproximaciones

An Integrated Study of Natural Springs to sustain water security: Case Study of three villages from a Himalayan State of India

Equitable access to water, whether it is quantity or quality, is one of the fundamental rights. It facilitates economic development, gender equality and good human health. But in the last few decades, lack of potable water has caused illness and resulting millions of deaths. In Himalayan Region, springs are the basic water source which fulfills the needs of rural population. The point at which the groundwater emerges over the earth surface and flows naturally is called spring. Drying up of these springs, due to climate change and biophysical landscape change, is not only causing problem to human health, impeding gender equality but also causing nearby bio diversity to lose resilience. Therefore, a basic understanding of springs is required for its further studies and to maintain water security. This present work is focused on the initial steps of Spring Sanctuary development. The present outline emphasized on the spring mapping and has prepared a social database of springs of three villages of Saurakhaal nyay panchayat of jakholi block, Rudraprayag, Uttarakhand. The status of the springs has been assessed by monitoring their discharge data for eight months (Nov, 2020-June, 2021). Also, the endangered and vulnerable springs of the study area has been identified by scoring them on the basis of critical issues

Applicability of hydrogen fuel cells in shipping for a sustainable future

 From 2020, International Maritime Organisation (IMO) rules have banned ships from using fuels with a sulphur content above 0.5 percent, compared with 3.5 percent before, unless they are equipped to clean up sulphur emissions. This will be enforced by fines levied by the IMO’s member states. One of the attempts being made by the shipping industry to reduce its environmental impact is to use Fuel Cell Technology to deliver power to the vessels. Fuel cells as clean power sources are very attractive for the maritime sector, which is committed to sustainability and reducing greenhouse gas and also atmospheric pollutant emissions from ships. Fuel cells operating on hydrogen fuel are an efficient, environmentally-friendly, zero emission, direct current (DC) power source already applied to heavy duty bus, truck, and train applications, and are now under development for marine applications. The only emissions from a fuel cell are water vapour and some heat [1].Renewable hydrogen, generated from solar, wind, hydroelectric, and geothermal sources is considered an ideal fuel for decarbonising society. It can be used for industrial purposes, power generation, heating, and as a transportation fuel. This paper aims to show how the Hydrogen fuel cell systems are one of the best options for ships to meet the future and present IMO environment requirements, along with the challenges and conveniences of using renewable hydrogen compared to traditional marine fuels including a feasibility study of a Hydrogen fuel cell powered ferry. Keywords: IMO (International Maritime Organisation), sulphur emission, Fuel cells, sustainability, Greenhouse Gas, Hydrogen

Seismic pounding effect on two adjacent RC framed multistorey buildings using time history analysis.

Seismic pounding is defined as the collision of structures during earthquakes when these structures have different dynamic characteristics. It is an instance of rapid strong pulsation like hammering and repeated heavy blows. This pounding of closely spaced buildings can be seen largely in some densely populated urban areas. Some modern codes have included seismic separation gap requirement clauses for adjacent structures but since large parts of metropolitan cities in seismically active regions of India were built before such requirements were introduced, the seismic separation gap requirements have not been fulfilled. Pounding can be catastrophic and even more dangerous than the effect of earthquakes on a single building. Thus, the action of pounding of buildings needs to be mitigated to avoid loss of life and property during earthquakes. The problem of pounding is particularly common in many cities in India, located in seismically active zones, where due to various socio-economic factors and land usage requirements, buildings are often constructed crowded together. This paper is focused on the study of the seismic pounding between two RC buildings with different dynamic characteristics. A systematic study of response of seismic pounding between adjacent buildings and seismic hazard mitigation practices like effect of different separation distances and effect of providing dampers are investigated, using the ETABS software. A 12-storey and a 16-storey building have been considered for the study of pounding. Time history analysis is carried out for seven real earthquake ground motions on the models with varying separation gaps. The results were obtained in the form of pounding force and point displacements. It is revealed that the pounding effect varies inversely with the separation distance. With increasing separation distance pounding effect is reduced greatly and so the damage to the neighbouring buildings is also minimized. Also, the pounding forces are seen to be decreasing considerably between the adjacent buildings due to the provision of dampers at suitable locations, as compared to the case of adjacent buildings without dampers. The study even confirms that the pounding effect can be mitigated considerably by installing dampers between adjacent structures. Dampers modelled in this study prove to be effective in reducing the displacement and drift in the range of 15%-20%

Effect of sintering and coldbonding techniques onlightweight aggregates fromindustrial waste – a review

Concrete is a building material which consist major portion of hard inorganic materials called aggregates such as crushed stone aggregate. Due to continuous usage of natural resources within a short length of time these get depleted. Production of concreteby using waste materials from industries is important in this era. The production of light weight aggregate from waste material is done by pellatization and hardened by sintering or cold bonding techniques. Depending upon the hardening methods the properties of concrete is also varied. From previous research works it can be concluded that it is possible to produce structural concrete using sintered fly ash aggregate which are spherical in shape having specific gravity varying from 1.33 to 2.35. According to the literature, the specific gravity of these aggregates was 16 to 46 percent lower than that of standard of weight aggregates, and they might be employed as aggregates in structural concrete production depending on the constituent qualities and the production environment. Cold bonded aggregate concretewith compressive strength 48% lesser compared to normal concrete mix, it exceeds the value of 17 MPa that has been fixed as minimum criteria for concrete to be used as a structural material. This paper mainly focuses on review of artificial light weight aggregate from cold bonding and sintering methods and how these methods affect the concrete properties. From different studies, it is concluded that Cold bonding is an energy saving method and Sintered sludge pellets have a stronger aggregate strength, larger porosity, and lower aggregate density than cold bonded aggregates, exhibiting qualities that are superior to those required of building aggregates. Sustainable development is indeed achievable in this developing era and lightweight aggregate in construction sector is key to achieve this

Correlation between female literacy and sex ratio in Rajasthan: a geographical analysis.

ABSTRACT Education changes the awareness of the society, so literacy responsible for the changing pattern of sex composition of any region. The study triumphs that Literacy has vital effects on the sex ratio. Therefore, the present paper is aimed to analyze the Correlation between female Literacy and Sex Ratio in Rajasthan using data collected by the 2011 census. Spearman’s Rank Difference method is used to analyze the correlation between literacy and sex ratio. The study reveals that the correlation between female literacy and sex ratio is r= -295. It is a moderate negative correlation. The female literacy and sex ratio have moved the opposite direction in Rajasthan. The sex ratio has been found higher in districts, which have low female literacy. Kota district has registered the highest female literacy of (65.9%) but it has a very low sex ratio of 911. Key Words: Sex-ratio, female Literacy, Correlation

Endocrine disruptor pesticides on non target pollinator

Endocrine disrupting chemicals (EDCs) are substances that disturb the endocrine system's normal function, potentially causing sickness or deformities in organisms and their progeny. Pesticides are commonly employed to destroy undesired organisms in crops, public places, houses, and gardens, as well as to treat parasites medicinally. Many have been identified as EDs or are suspected of being EDs. Pesticides applied to agricultural or horticultural landscapes were the predominant, if not exclusive, source of pesticide exposure for honey bees and the source of hive product contamination until the early 1980s. Pollinators, such as honey bees, are responsible for the successful reproduction of over 87 percent of flowering plant species, making them critical to ecosystem health and agricultural productivity. &nbsp

A review of soil and soft-scape material management as a sustainable intervention for the execution of landscape in residential projects of Pune

Landscape is an integral part of today’s urban residential projects. As far as Pune is concerned, it has seen a rapid rise in the number of residential projects over the last decade. In many of these residential projects, landscape development is done either by landscape architects or by architects. Overall, development takes place over two to three years and landscape development is done at the end of projects. Further investigation by interviews and field observations carried out during this research process pointed out many issues in the planning and execution stage of the project. Issues observed in the execution stage were mostly related to natural materials like soil, plants and water. These are precious resources for landscape projects and their loss is not measurable in terms of money.  Also, they are difficult to replenish. Improper planning w.r.t. project timeline is also responsible for wastage of topsoil and plants. This identifies the need for management during the execution of landscape. Thus this paper aims to review the need of Soil and soft scape material management-plan as a tool for sustainable, economic and season-wise scheduled landscape development in residential projects as per construction management principles.&nbsp
