Déterminants de la malnutrition dans un pays à faibles revenus : étude descriptive sur 422 gardiens des enfants et ces enfants âgés de 6 à 23 mois révolus vivant à luwowoshi / lubumbashi/ rd congo

En République démocratique du Congo, un enfant sur deux est malnutri et cela constitue un problème de santé publique.Les projections internationales révèlent que sur un total de 52 millions d’enfants en malnutrition aiguë, 33 millions souffriraient de la malnutrition aiguë modérée. Objectif: déterminer les facteurs qui sont à la base de la malnutrition à Luwowoshi, en explorant: la prévalence de la malnutrition, le score de la sécurité alimentaire, le statut vaccinal, les connaissances et pratiques sur l’alimentation du nourrisson et du jeune enfant.

Design and implementation of toxic gas monitoring system

The primary notion of gas leakage detection is the implementation of a protection framework for the detection of gas leakage in a closed environment. In the current situation, there are various criteria linked with gas leaks that have an influence on the lives and property of innocent people. This warning system, which can save people's lives, can be advantageous for businesses and homes. In this project, a SIM900 (GSM module) is utilised to complete the desired task by combining a gas sensor (MQ6), a buzzer, an Arduino UNO, a 5V stepper motor, and an LCD display.

Comparative assessment of visual and passive acoustic detection of cetaceans in a 4-d seismic operation, agbami, South-South of Nigeria

The detection result of acoustic monitoring was compared to visual observations in a 4-D seismic survey. Data was collected on board The MV Osprey Explorer (Seabird)cruising at the speed of 4.6 ±4 nautical miles.

Conceptual model and didactic strategy for dificulties reduction by integration of computer systems on analitical geometry teaching at education higher institut of cabinda

This article was developed in order to model the integration of computer systems, GeoGebra and MS-Excel, in the teaching-learning process of Analytical Geometry at the Higher Institute of Educational Sciences in Cabinda, in order to reduce the difficulties that appear as, Lack of mastery of the basic concepts of Analytical Geometry, little motivation of students, limited understanding of the concepts of vectors, equations of lines, their representations and graphical interpretations in the plane and space, conic sections, quadric surfaces, poor preparation in the use of software mathematici

Estimation of the optimal tilt angle for solar photovoltaic modules in ilaro town southwestern Nigeria

Solar energy is the radiative energy that comes from the sun. Solar radiation is electromagnetic in nature and its spectrum cover the ultraviolet (UV) through the visible (VIS) to the infrared (IR) part of the electromagnetic spectrum. The data used in this study was a 12 years average solar radiation data between year 2009 and 2021.

Hg2+-fluorescent probe based on naphthalimide derivative

Naphthalimide has been widely used in probe research because of its unique structure. Therefore, using naphthalimide as matrix, a compound P was obtained by the reaction of pyridine-2-formaldehyde with naphthalimide derivative. Among the tested metal ions, the addition of Hg2+ to the solution of P in ethanol quenched the fluorescence of P at 525 nm, and a linear relationship between fluorescent intensity tothe concentration of Hg2+ in the range of 2.0×10-6-1.6×10-5 M was observed.

After a functional analysis of the SIP protocol and based on the work of researchers of the University Italian (University of parma-Italy) (University of parma-Italy)to acquire adequate libraries for the development of our communication tool.

Assessment of seawater flux and its impact on ayetoro coastal community of ondo state, Nigeria

Climate change impact had given rise to incessant flooding exacerbated by high tidal fluctuations, sea level rise and its accompanying negative impacts such as land degradation and seawater incursion into freshwater sources. Hence, the need to assess the hydrochemistry and anthropogenic pollutants in water, sediment and representative fish samples of Aiyetoro coastal waters.

Introduction: A pseudoarthrosis is established after a minimum of nine months after the trauma without progressive visible signs of consolidation for three months1.

The environmental awareness in Ṛgvedic period

Environment is an un avoidable part of human life. The are Vedas gives various references in the environmental protection, ecological balance, weather cycles, rainfall phenomena, hydrologic cycle, etc. The protection of the environment was understood to be closely related to the protection of the heavens and earth. Many of the Ṛgvedic hymns therefore vividly describe the Heaven and Earth together.
