Protein deficiency could be appearing in the future, because of the population growth, so the alternative protein sources will play main role in the nutrition of human population. In our research we used alfalfa(Medicago sativa) as alternative protein source, from which we could create a leaf protein concentrate. The isolation of leaf protein resulted a very large amount of brown juice and it has a harmful effect on the environment. For example it can cause eutrophication.
Accidental spills of oil products and the release of oil products into water bodies can also lead to deterioration of health and life of the population. Are there effective, affordable, environmentally friendly ways to eliminate oil pollution? What natural materials are the most effective for removing oil and gasoline from water surfaces? The search for answers to these questions became the main reason of our research.
Hypothesis: plant fibrous materials can be used for the sorption of petroleum products when they enter water bodies.
Thus, the hypothesis that it is possible to find available plant materials with the help of which it is possible to collect effectively oil and oil products from the surface of the water has been confirmed.
The San Pedro River, located in the border of Mexico and Guatemala, is of great importance to the Mayan culture, connects a wide wetland network, and is a revenue source to local communities, but is being affected by pollution and the growth of aquatic weeds. The rural border communities also face the scarcity of commercial fertilizers, which hinders their participation in productive programs. Here, we studied the potential use of aquatic weeds such as Eichhornia crassipes, P. stratiotes, and Salvinia molesta, to produce a biofertilizer. After performing physicochemical analysis, germination, and growth tests, we scientifically confirmed that the Biophyte fertilizer is safe and adequate for use by farmers. Finally, we also worked along the community to create know-how and awareness.
Este proyecto presenta un sistema de recogida de agua de lluvia que reutiliza botellas de PET, que interconectadas con otras botellas forman un depósito de agua vertical, compacto y resistente a las presiones, que ocupa un espacio reducido. El proyecto tiene como objetivo satisfacer las necesidades de ahorro de agua de la Escuela Primaria Guillermo Frías, ubicada en Mecapaca (Ciudad de La Paz); esta zona presenta constantes problemas relacionados con el suministro de agua. El sistema tiene una función similar con Ekomuros, pero a diferencia de ellos, tiene un sistema de filtración basado en el uso de cáscara de quinua, que contiene saponina. La saponina es un antifúngico;que elimina hongos y bacterias, también hace espuma, por lo que el agua recolectada se puede utilizar en los baños de los niños de primaria de la escuela.
The water crisis in megacities intensifies as we don’t realize how much water we use or how much we waste. The primary purpose of this paper is to reduce water usage and wastage to conserve water resources. In this paper, we tried to develop an integrated system, which will help people track every individual’s water usage and predict their water usage habits to suggest more efficient behaviors and be easy to implement and popularise in megacities. Moreover, the system includes greywater reuse by recycling greywater to reduce unnecessary water usage and prevent wastage. Finally, the proposed system will help us to reduce water wastage and conserve our limited resources.
As the world’s population grows, the demand for food is growing as well. Therefore we need to handle our agricultural grounds with all love and care it needs. Fertilizers are essential in the optimization of the soils. In this project the effect of particle size in fertilizers was researched, especially in dried organic compounds like hay. Firstly the concentration of soluble content out of dead organic material in various particle sizes was looked at. After the first experiment the influence of particle size on water absorption and retainment was researched. In this manner water can be used as efficiently as possible, which leads to less water needs and higher yields. This shows why size matters.
Neonicotinoids are widely used pesticides whose harmful effects on biodiversity have been long recognized. This work analyzes the incidence and prevalence of five neonicotinoids in four different taxa of aquatic invertebrates in three sites of the Seyon River, in Switzerland. All samples analyzed were contaminated with at least one neonicotinoid, and two neonicotinoids found in the samples had been banned from use nine months prior to sampling: these facts highlight the substances’ ubiquity and high persistence in natural environments. The concentrations indicated a chronic exposure to neonicotinoids, except for one value which was ten times bigger than the others. These alarming results encourage further studies on the subject, in which the experimental methods developed for this work could be exploited.
Satellites have become an essential part of our everyday modern life. Especially weather satellites as they provide a basis for weather forecasts from a unique perspective. However, did you know that anyone, anywhere, can receive images and data directly from weather satellites with low-cost equipment? The objectives of this study revolve around the UN’s Global Goals for sustainable development and how to introduce more accessible and democratic ways of conducting water and climate research. This study, therefore, examines if it is possible to conduct a scientific study with images directly from these weather satellites. The study presents a novel way of analyzing sea surface temperature (SST) in the Baltic Sea region and its development during the fall of 2020.
