Imaginar otro mundo es posible: la producción del futuro en los tiempos del Antropoceno
No full textThis essay explores the study of future, related to environmental changes in the contemporary world and their representations. In everyday life, it is very common to find images about the environmental crisis in the planet. In the perspective of a sociology that takes the future as an object of inquire, the images that anticipate other states of the world have powerful consequences in the present. Social sciences are central to analyze, debate, and achieve the anticipated futures. In the present, the high circulation of images about climate futures and the limited possibilities of acting significantly, produce a state of reflexive impotence. Anthropocene is the name of the current geological age. This concept problematizes our way of conceiving the world, posing questions about the way in which the human and the non-human entangle their domains. On one hand, Anthropocene anticipates harder climate conditions in the times that come. On the other hand, it invites to look for new ways to produce better futures and inhabitable worlds. All the efforts to achieve this purpose are equally necessary. Different anticipation dispositives, like climatemodels, fictions and mythologies have a crucial role in the task of producing future worlds.Este ensayo explora el estudio del futuro, en relación a las transformaciones contemporáneas del medioambiente y sus representaciones. En lo cotidiano, el encuentro con imágenes que reflejan las crisis ambientales por las que pasa el planeta es algo común. Desde una sociología que toma al futuro como objeto de investigación, las imágenes que anticipan otros estados del mundo tienen poderosas consecuencias en el presente. Las ciencias sociales son centrales para analizar, debatir y alcanzar los futuros así anticipados. Sin embargo, la alta circulación de imágenes sobre el futuro climático, junto con las limitadas posibilidades de actuar significativamente en el presente, producen una sensación de impotencia reflexiva. El Antropoceno, nombre propuesto para designar la actual época geológica, problematiza nuestra forma de concebir el mundo, planteando preguntas sobre la forma en que lo humano y lo no humano enredan sus dominios. Por un lado, el Antropoceno anticipa condiciones climáticas mucho más duras en los tiempos que vienen. Por el otro, invita a buscar formas de producir nuevos y mejores futuros, donde existan mundos habitables. Todos los esfuerzos por alcanzar este fin son igualmente necesarios. Distintos dispositivos de anticipación, como el modelamiento del clima, la ficción y las mitologías, juegan un rol fundamental en la tarea de producirmundos en el futuro
A sustainable approach for synthesis of zinc oxide nanoparticle by Aloe barbadensis and its application in photocatalytic decolouration of commercial dyes.
Full text linkZinc oxide nanoparticles (ZnONPs) biosynthesis is gaining popularity since it is environmentally safe and can withstand a wide range of environmental conditions. The widely known medicinal herb Aloe barbadensis was employed to create ZnONPs in this work. XRD (X-Ray Diffraction), EDAX (Energy dispersive X-ray microanalysis), and TEM (Transmission Electron Microscopy) were also used to characterise the produced ZnONPs. In XRD, the produced ZnONPs revealed crystalline character, with an average size of 30 50 nm. TEM was used to determine spherical morphology. Under ultraviolet irradiation, the photocatalytic decolorization of Sudan IV, Crystal Violet (CV), and Acridine Orange (AO) by biogenic produced ZnONPs was studied. Using all three dyes (10-50 ppm) throughout a 4-hour incubation time, the produced ZnONPs showed 100% photocatalytic decolorization activity
 
Characterization and property analysis of starch from broken parboiled rice
Full text linkRice (Oryza sativa L.) is the primary food consumed by half of the world’s population and it provides 40-60 per cent of energy in daily diet. Production and consumption is anticipated to grow steadily every year. Rice is the rich source of starch, a polysaccharide consisting of amylose and amylopectin. Broken rice is the by-product and a key indicator of rice quality. Nearly 14 per cent of rice is broken while milling and during threshing process. The present study was carried out, to compare the properties and utilization of broken rice with whole rice. Alkaline extraction process is the best extraction method to isolate starch from broken rice that yields upto 70% of total starch with fewer residues. The characterisation of extracted starch from broken parboiled rice was investigated by Fourier-Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), Thermo Gravimetric Analysis (TGA), Field Emission Scanning Electron Microscopy (FESEM). The quality of starch from broken rice estimated through physical, thermal and physiological properties show a similar property as like starch extracted from rice. It is the colourless and odourless compound which doesn’t affect the colour and flavour of the product to be added that can be easily used in food industries at low cost. This study paves a way to utilize broken rice, a food industrial by-product and agro residue in an effective manner.
Key words: broken rice starch, property analysis, industrial by-product, agro residue, characterization, alkaline extractio
Rethinking indigenous and ecological building materials through the means of additive manufacturing
Full text link Additive manufacturing or 3D printing can be a feasible strategy that can significantly reduce the time and manual labor required and translate into skilled labor and reduce the wastage of material required during construction. The process in all would also be cost-effective (van Woensel et al. 2018). The challenge posed is the proper implementation of additive manufacturing for full-scale clay-based building materials.
Clay-based architecture or mud architecture has been prevalent in India for centuries. Mud construction techniques have been utilized in various climatic zones based on the context and cultures. The versatility of the material allows it to be used as small modules like mud bricks and tiles to grandiose rammed earth walls. It is a highly adaptable material that can change its function as per the strategies used. Another important aspect is the skilled labor that is required to achieve clay architecture techniques (Salas, L. 2022). The rise of cement construction has affected skilled labor, forcing people to migrate to the cement construction sector. The essence and knowledge of these vernacular construction strategies are thus slowly disappearing.
This study will be a significant part of realizing the usage of local material to develop future habitable spaces. The help of innovative material systems and 3D printing will help incorporate traditional materials and translate them into solving dwelling problem
Analysis of Public Awareness about District Disaster Management Plan: A Case of Dehradun City
Full text linkSince 2000, at least 5,731 people have perished and over 2,000 have been wounded in natural disasters in Uttarakhand, the majority of which were caused by flash floods and landslides, as per data provided by the state's disaster management agency. Natural disasters are common in locations near the Himalayan Mountains. The goal of the research is to examine public knowledge, understanding of natural disasters that have happened or are anticipated to happen in the city, as well as the city's disaster preparedness and management, to find gaps in the District's Disaster Management Plan (DDMP) for its inhabitants. A pilot survey with 50 respondents was undertaken to determine the level of public awareness. The study concludes about awareness amongst the citizens for the DDMP and recommends ways of public engagement and incorporate their views into future management activities
A Study to Evaluate Urban Heat Mitigation Design Strategies, In Commercial Centers.
Full text linkThe rapid rate of urbanization, especially continued growth and anthropogenic activities has given rise to numerous urban climate impacts across different cities round the world. In India most of the cities specifically those with commercial centers are more at risk of induced urban heat effects thanks to intense radiation during most of the year, resulting in increased atmospheric air temperature and outdoor/indoor discomfort. The auto – dependent planning of the town contributed negatively to the external thermal comfort and to people’s daily social lives. One in every of the largest challenges for cities with hot climate is to search out effective solution against the induced urban heat increase and to boost the outdoor thermal. Considering the present scenario, over half of the earth’s population resides in urban areas. The amount of urban inhabitants is predicted to grow exponentially, especially in developing countries. The enlarging urban population would require an extensive array of infrastructure, services, housing and jobs etc. The urban land expansion could be a threat to land supply, causing intra-growth of the traffic volumes and increment in adverse pressure on the environment and may become immensely unsustainable for any city. Thus, the need of the hour is to take measures on variety of indicators that have outreached critical levels, especially the UHI and subsequently responsible choices need to be made for the new future so-as to push human and environmental resilience as we all must heal this warming world

Mapping women’s role in small scale fisheries value chain in India for fisheries sustainability
Full text linkSustainability in small scale fisheries is receiving wider acceptance worldwide as the system faces different kinds of exploitations. Gender can play a significant role in achieving sustainability as they are the primary beneficiaries in small scale fisheries. Exploring their level of participation in resource use can provide a database that functions as the key determinants for sustainability. This article looks for empirical evidences on the role of men and women in small scale fisheries through gender structure analysis. The indigenous communities (n=154) in Vazhachal Forest Division, Kerala, southern state in India is considered for the study. Methods adopted includes household survey using semi structured questionnaire, transect walks, focus groups and direct observations. Results reveal that although higher percentage of men (66.20%), women’s role is substantial (33.80%) in fisheries value chain including pre harvest, harvest and post-harvest sector. Their presence had a significant relation in supporting men in fisheries activities like collection of baits (χ2= 6.189, p= 0.013), accompanying men in fishing (χ2= 4.153; p= 0.042), sorting of fishes (χ2= 3.566, p=0.059), processing of fishes (χ2=9.776, p= 0.002) and in mending of nets (χ2= 4.40, p=0.042). Results, further, reveal that men and women have unique and overlapping roles in small scale fisheries. The key findings of the study provide quantitative evidence to develop strategies for small scale fisheries sustainability

To study the effect of dietary modification on haemodialisis patients
Full text linkChronic kidney disease is a world wide public health challenge since patients with end-stage renal disease (ESRD) have to live on hemodialysis (HD) for the rest of their lives unless a kidney donor and a successful kidney transplantation is carried out. Patients on HD have increased mortality compared with the general population. Several factors can play a negative role and increase risk of mortality among HD patients, particularly cardiovascular diseases.An important non cardiovascular risk factor of mortality among HD patients is malnutrition. Malnutrition in HD patients is due to restrictive food recommendations, poor appetite, and drug-related factors. Protein energy wasting (PEW) are common in patients with chronic kidney disease (CKD), especially in patients on dialysis either on haemodialysis or peritoneal dialysis. One of the most important factors affecting the quality of life of chronic kidney disease (CKD) patients is nutrition. Prevention of malnutrition increases patients quality and length of life. The aim of this review is to discuss the role of dietary modification of patients on dialysi
