Evaluation of biogas production and usage potential
2016
The aim of the research is the development of theoretical and methodical bases for determining the feasibility of plant raw materials growing for its further bioconversion into energy resources and tec hnological materials to maximize profit from business activities. Monograph, statistics, modelling and abstract logical methods have been used during the research. Directions of biogas usage have been examined. Biogas yields from different crops have been analyzed. It has been determined that high methane yields can be provided from root crops, grain crops, and several green forage plants. So, forage beet and maize can provide more than 5,500 m3 of biogas per hectare. Attention is paid to the…

Pathways for the amplification of agroecology in African sustainable urban agriculture
2020
A growing awareness that highly intensified agricultural systems have made a substantial worldwide contribution to the worsening of the resilience capacity of natural ecosystems has, over the last twenty years, brought general attention to agroecological management models. This aspect is even more evident in industrial agriculture, which is based on the use of multiple chemical products derived from non-natural synthesis. In more developed countries, a new idea of ecology linked to agricultural production has been increasingly developed and, for this reason, there has been a greater diffusion of differentiated agricultural models taking into consideration the environmental impact of product…
Contrasts in fitness, motor competence and physical activity among children involved in single or multiple sports
2021
Abstract Study aim: While there is wide debate around specialization in one sport, there is a lack of information about fitness levels and motor competence of children participating in single or multiple sports. Material and methods: The study involved 358 fifth-grade children who participated in a set of health-related fitness and motor competence tests over two consecutive years. A subsample of children (n = 109) wore an accelerometer for seven consecutive days. The independent samples t-test and ANCOVA were used to compare differences between single and multi-sport participants in study variables and changes between baseline and follow-up. Results: Multi-sport participants performed bett…
Alianzas antiembalse y luchas hidroepistemológicas. Los retos de la gestión colectiva del agua en el Río Grande, Málaga, España
2018
En este artículo analizamos las luchas epistemológicas y retos que ha tenido el movimiento social en la subcuenca del río Grande frente a los diversos proyectos modernizadores que intentan transferir el agua rural hacia la ciudad de Málaga. El primero asociado a la construcción de un gran embalse y el segundo con la modernización de los sistemas de riego tradicionales. Concluimos que el reto está en desenmascarar el régimen de verdad que respalda los proyectos de modernidad hidráulica, reivindicar los derechos de uso y control colectivos del agua y así generar procesos de apropiación comunitaria para la defensa del río como un bien socio-ambiental, económico-cultural y político-epistemológi…
Roczna wydajność instalacji PV zamontowanej na dachu budynku dydaktycznego Uniwersytetu Opolskiego
2018
Celem badań była analiza i ocena sprawności pracy instalacji fotowoltaicznej zamontowanej na dachu budynku dydaktycznego Uniwersytetu Opolskiego mieszczącego się przy ul. Kominka 6 w Opolu. Zakres pracy obejmował ocenę: energetyczną - uzysku energetycznego (ilość wyprodukowanego prądu a położenie geograficzne paneli fotowoltaicznych) i ekologiczną - redukcja emisji szkodliwych substancji niewyemitowanych do aerozolu atmosferycznego z powodu produkcji prądu przez instalację PV, a niedostarczonej przez elektrownię opalaną węglem. Badania wykazały dobry wynik uzysku energetycznego w ciągu roku - 5,30 MWh energii z tego systemu oraz znaczną redukcję emisji CO2 do atmosfery - 4,27 Mg/rok, co pot…
