Agriculture in Burkina Faso faces a number of difficulties, including climatic constraints and poor soil conditions. Added to this is the high cost of chemical fertilizers. However, effluents such as pig slurry are multiple sources of plant nutrients, and would enable more eco-responsible management of these dejecta. The study was conducted over two consecutive years at the FarakoBâ experimental station in Burkina Faso. The experimental set-up is a completely randomized fisher block.

This paper analyses why traditional market models, such as perfect competition,monopolistic competition, oligopoly, and duopoly, are not suitableforthe dynamics of digital business platforms. While these models were developed for traditional physical goods and services markets, digital platforms introduce unique characteristics like network effects, low marginal costs, multi-homing, and data-driven competition that alter the competitive landscape.

Natural resources are facing serious degradation all over the world as a result of rapid population growth. This galloping population puts pressure on agroforestry ecosystems around the world. Yet, developing countries do not have methods to appraise the economic value of services provided by these ecosystems. They offer many opportunities to improve people’s livelihoods. However, trapped in the socio-economic development process, agroforestry faces different threats including: deforestation, soil degradation, pollution, overexploitation of biotic and abiotic resources, etc.

Growth finance institutions are essential for financing economic growth. These specialized banks cover gaps in the market. They provide long-term financial options that are often not accessible through traditional banks. They focus on funding development projects in regions that are neglected by conventional lenders. To address significant financial gaps, DFIs employ infrastructure loans, equity investments, and technical assistance. They help spark private investment for social and economic progress.Development Finance Institutions (DFIs) are specialized financial institutions.

For better watershed control, protection, water resource planning and seabed development; it is important to aquire master the its physical environment. The aim of this study is to understand the hydrological functioning of the watershed through its physical environment in order to successfully manage it. The data from the 30 m resolution Shuttle Radar Topographic Mission (SRTM) and the 1/200,000 scale urban mapping of the study area were used. The description of the watershed showed that it is an elongated and covers an area of 498.78 km2.

The aim of the work was to produce a geological and structural map of the Ouaddai massif using landsat and radar data. We used landsat-8 images to extract the lithological map (colour composition and ratio bands) and PALSAR DEM radar to extract the lineament map (using different filters). For the radar sensor, a total of 2188 lineaments were detected and extracted, with two main rock fracturing directions (ESE-WNW (90° to 115°) and NE-SW (45° to 65°)).

The present work aims to determine the influence of the nature of the combined materials on the measurement of the conductivity of an aqueous ionic solution. In this study, 4 types of electrodes (iron (Fe), copper (Cu), aluminum (Al) and lead Pb) were used. Correlation curves, current intensities and the degree of mineralization of the solution were layout. The correlation coefficients varying between 0.9877 and 1 indicate a very good correlation between the degree of mineralization of the ionic solution and the intensity of the measured direct current and the reliability of the method.

The study aims to identify the impact of scientific and technical advancements made possible by two essential components: clear visions and plans. Educational plans for developing education, whether at the national or self-education level, are crucial for human resource development, establishing information and communications infrastructure, and integrating communication technology in education stages, particularly in continuing education.

Currently, computers and the internet are two “things” that cannot be separated. Computers have become “information management centers”. Information is received, stored, retrieved, processed and then exchanged (shared) everywhere. The question of where the information is obtained and then shared means nothing if there is no such thing as the ‘internet’. Does the computer have to be in the form of a ‘Personal Computer, PC?”, ‘Note Book’ or ‘Laptop’. No. The android phone that we hold (we call it a “cell phone”) is also a computer. Cell phones also utilize the internet.

In the current context of increasing concerns regarding energy efficiency and environmental impact, the management of waste heat recovery is essential for various industries. This article explores modern methods and technologies for waste heat recovery, focusing on energy efficiency and sustainability. We examine processes for capturing and reusing waste heat from industrial and commercial sources, assessing their impact on overall energy consumption and greenhouse gas emissions.
