Abstract: The housing of rabbits is related to hygienic, behavioral, environmental and welfare aspects. Cleaning and disinfecting is imperative to maintain the wellbeing and health of animals. Thorough cleaning and adapted disinfection can help decrease the pathogen level and prevent or break the disease cycle. In this experiment we aimed on the efficacy of disinfection by using disinfectant SANDEZIA® in powder form applicate by scattering on the plastic or wooden floors of cages at a dose of 50g/m2. Total count of bacteria, yeast, molds and coliform bacteria were collected from both type of floors of with microbiological swabs before and after disinfection. Disinfectant SANDEZIA® was effective on monitored floors where significant decrease of microorganisms, except molds was obtained. After.....

Abstract: The study aims to determine the dosage effect of cow manure and NPK pearl fertilizer on growth and production of cucumber (Cucumis sativus L). The study used two factorial Randomized Block Design (RAK), the first factor was cow manure at three levels, namely: k1 = 3 kg plot-1 equivalent to 10 ton ha-1), k2 = 4.5 kg plot-1 equivalent to 15 ton ha-1) and k3 = 6 kg plot-1 equivalent to 20 ton ha-1) the second factor was NPK Pearl fertilizer namely: n1 = 60 g plot-1 equivalent to 200 kg ha-1), n2 = 90 g plot-1 equivalent to 300 kg ha-1) and n3 = 120 g plot-1 equivalent to 400 kg ha-1). The results showed that the dosage of cow manure (k) had a significant effect on the number of fruits harvested (first harvest). While the dosage of NPK Pearl fertilizer (n) had a significant effect on the average number of leaves at 14 DAP. The interaction both factors had a significant effect on the number of leaves at 21 DAP.

Abstract: The socio-economic impacts of major mining projects are complex and controversial. Their effects on water create a considerable ecological imbalance in both the environment, the economic and social characteristics of the indigenous people. The study was conducted in the villages of Liambe, Likombe, Ilongo-Mbutu, Ilongo-Koki, Yangonde-Lioto, Yakoyo, Bomane, Baonde…, in the Territory of Basoko (DRC), which are targeted for semi-industrial diamond mining. The research was used an action-research approach which was completed by three techniques (documentary, focus-group and semi-structured interview). Mining projects are likely to adversely affect the environments, communities, and economies inherent in the projects and their contexts. Mineral exploitation often creates wealth for a category of people; however, it can also cause considerable disruption. The benefits and consequences can.......

Abstract: It has been observed and concluded, over years of research that, hydrogen is one of the most unparalleled energy carrier of this century, having said that, it still has a lot of untapped potential when it comes to commercial usage. It is evident that an ample amount of research is being carried out to obtain an efficient method for the production of different types of hydrogen, under the clean energy initiative, which has been a prime focus across the globe.There would be no useful organic compounds to form the building blocks of life without it. This study focuses on types of hydrogen and its specialties which has ample real world mapping in areas like petroleum refining, power generation and as an energy carriers. The one in more abundance is grey hydrogen but in the not so distant future green hydrogen will be the hot topic. Outstanding methods do not have any specifications regarding carbon capture but we can have plants which will absorb carbon or conservation of CO2 can be stifled by chemisorption. New strides are being made in this field everyday with discoveries of new ways of storing the hydrogen.

Abstract: Background: The present study examines a theoretical approach to Kuznets environmental curve and has led to some conclusions about the overall growth - environment relationship. The Environmental Kuznets Curve (EKC) and related approaches to human-environment problems generally posit an inverted U-shaped relationship between environmental degradation and economic development since economic growth is proportionally related to rapid environment deterioration due to air pollution, deforestation, soil, water contamination, and several other factors........

Abstract: The effects of various culinary methods notably scalding, frying, grilling, roasting, and drying of Macrotermes subhyalinus and Imbrasia obscura on the physicochemical and microbiological characteristics and the digestibility of their proteins were studied for the two insects consumed in Adamawa and East regions of Cameroon. The fat content of fried samples significantly (p <0.05) increased due to absorption of oil from the processing medium. It was not the case with the samples cooked using other methods. The comparison of results of raw and cooked samples showed that with respect to the cooking method, there is significant increase or reduction (p <0.05) of the contents......

Abstract: In Kenya, the wetlands are undergoing continuous human encroachment and anthropogenic activities that may affect their ecological integrity. This study was conducted to assess this impact by establishing macroinvetebrates species and indices along different disturbance gradients. Data was collected monthly and analyzed through frequency distributions, cross-tabulation, chi-square, and Analysis of Variance as appropriate. Macroinvertebrates species richness was found to be highest at Kesses site which was a relatively low disturbance area with 28 species, followed by site Kingwal Bridge with 24 species and site Kiptenden with 23 species while Kimondi had the lowest species.....

Abstract: A total of 43 surface sediments samples (0-20cm) were collected from Xiaoqing River Estuary (XRE), eastern China, the concentrations of As, Cd, Co, Cr, Cu, Hg, Mn, Ni, Pb, and Zn and grain size were measured. The mean concentrations of As, Cd, Co, Cr, Cu, Hg, Mn, Ni, Pb, and Zn were 9.36, 0.105, 8.42, 39.33, 9.84, 0.0165, 48.94, 17.31, 13.86, and 43.72 mg·kg-1, respectively. The sources of heavy metals were identified by US-EPA positive matrix factorization (EPAPMF). Three sources of ten heavy metals were identified by EPAPMF, showing that As, Cd, Co, Cr, Cu, Hg, Ni, Pb, and Zn are mainly controlled by natural sources with contributions from 59.8% to 88.1%; agricultural activities is associated with As (27.9%) and Mn (32.4%); 20.3% of Cu and 27.5% of Hg were affected by industrial activities and atmospheric deposition
