Abstract- In recent decades, climate index has become an important tool in hydrological studies. Accordingly, the implication of climate change in hydrological researches requires the assessment of historical and future climate characteristics to understand current and future processes for water resources management improvement. The aim of this study is to analyze historical rainfall anomalies over the Mouhoun watershed by applying precintcon package in R studio. Required data for the assessment of the rainfall anomalies was retrieved from the National Meteorological Agency (NMA) of Burkina Faso. Purposely, monthly rainfall data of three meteorological stations spanning from 1980 to 2012 were collected. The findings revealed that within Mouhoun watershed, the rainfall data are leptokurtic and the distribution is narrower than normal. This result shows thus a moderate dry rainfall anomaly. During the second period of analysis (1990-1994), The station of Bobo Dioulasso is showing an estimated value of -2.594. This value of the RAI is indicating a slightly dry pattern of rainfall in this station. However, the stations of Boromo, is presenting a value of RAI in the range of -1. 00 to -1.99 highlighting a moderate dry rainfall characteristic. During the period (1995-1999), slightly dry conditions are detected in Bobo and Boromo. From 2000 to 2004 and 2005 to 2011, moderate dry RAI index is identified for all station except for the station of Gaoua. Among these six stations of the watershed, Gaoua station which is located in the southwestern part of the watershed has experienced throughout the period of analysis a dryness conditions. Indeed, a slightly dry rainfall anomaly is detected with a RAI ranging from -0.50 to -0.99. The results obtained could serve as a guide to decision makers in water and climatic management.

Abstract- One of the most significant threats to the environment is posed by the ever-increasing generation of waste. This has resulted in an urgent need for global waste management techniques that integrate the ideas of recycling and reusing of the essential components of waste. The current technologies of waste management including incineration, landfills, and material recovery have not proven as useful as intended. These mostly outdated methods have resulted in generation of toxic fumes, health hazards, and high energy and operation costs. Thus, a unique, safe, hygienic, and sustainable method of waste management is essential.
Vermicomposting is a low-cost, eco-biotechnological process of waste treatment in which earthworms are used to biodegrade the organic waste into useful nutrient-rich vermicast. The products of this waste treatment process are disinfected, detoxified and nutrient-rich bio-organic fertilizers. The process not only recycles organic wastes, but also helps improve soil structure and contents. This review provides an insight into the design, operation, commercialization, and factors affecting the vermicompost reactors.

Abstract- The influence of actinomycete strain Streptomyces albogriseolus-89 (isolated from soils of Khevi region, Stepantsminda, Georgia) on growth and development, as well as the content of metabolites (chlorophylls, carotenoids, anthocyanins, ascorbic acid, proline, soluble phenols, total proteins, soluble carbohydrates) and peroxidase activity in leaves of durum wheat (T. durum Desf.) has been studied. It was established that inoculation of wheat seeds with the strain has stimulated stem and ear growth, positively affected protein content (raised by 12%) and peroxidase activity (increased by 1.3 times) as well as enhanced the yield and resistance of plant to biotic and abiotic stresses.

Abstract- The environmental health that nature offers us every day is closely linked to the sanitization provided by atmospheric chemistry, due to the oxidative processes that occur under the powerful sunlight passing through the clouds and reaching the forests, oceans, and seas, performs the multiple reactions, recombinations, mineralizations, degradations etc. in the atmosphere. It is a chain reaction called Open Air Factor (OAF) that cleans and disinfects the environment in which all living beings live called the biosphere.
There are technologies and elements necessary to be able to imitate nature in this process of environmental sanitization for indoor environments based precisely on the Open Air Factor (OAF), and for this, for a question of safety and efficiency, it is necessary to measure the quantitative proportions or mass ratios of the chemical elements involved and that are involved in this natural chemical reaction, as well as to study the proportion of the various resulting elements and the composition of chemical mixtures of the components.
The comparison of this stoichiometry that nature provides us with similar artificial systems for interiors will give us a vision of how similar the processes and resultants are.
This paper is based on the stoichiometry and kinetics of hydroxyl radicals emitted by a device technologically based on the Open Air Factor (OAF) aimed at controlling indoor air quality.
Specifically, it has been the analysis of the decay of the number of molecules of hydroxyl radicals (OH·) when reacting in the presence of typical air pollutants such as CO2, hydrocarbons and bicarbonate ions. These amounts of hydroxyl radical molecules (OH·) under study, unlike the multiple reactants that exist in Nature, have been generated with only two reactants, hydrogen peroxide and ozone, following current international safety regulations regarding their emissions in the presence of people.
