Road traffic injuries (RTI) are worldwide health and constitute an oversized majority of the deaths caused by all injuries. Every year the lives of approximately 1.35 million people are died as a result of a road traffic crash. Between 20 to 50 million more people suffer non-fatal injuries, with many incurring a disability as a result of their injury. we are introducing the automated alert device for vehicle accidents. The proposed system detects the accident and sends the data in less time to emergency services like 108 in India.

A method has been provided for the disinfection of water polluted by bacteria comprising administering zero-valent iron to the water in the presence of oxygen. This administration lead to the hydroxyl free radicals generation assuring the disinfection of contaminated water. A method has been used to proof the generation of free radicals.

In this paper, we applied linear transformations in the graph theory. Firstly, we constructed vector spaces of a finite number of elements over the field F={0,1}.Then we used them to construct linear transformations (in fact linear operators), defined on each of the vector spaces of the degrees of the vertices;〖(D〗_V,+_V,._V); the vector space of the vertices;(V,⨁▒〖,⨀)〗 ; and the vector space of the number of the paths between the vertex a and the other vertices;〖(P〗_a,+_P,._P);.The last linear transformations is defined from V into D_V.

Les changements climatiques influent sur la production agricole. La présente recherche se propose d’analyser les effets des changements climatiques sur la production de riz dans les départements du Zou et des Collines. Pour ce faire, des données sont collectées au Météo-Bénin, au MAEP/DSA et de la CT-SAGSA couvrant la période de 1987-2016. Ensuite, il a été procédé à une analyse descriptive de ces données, à une modélisation économétrique suivant l’approche ARDL au moyen des logiciels Excel et E views.

Inadequate supply of vitamin A is among the most pressing challenges facing developing countries including Nigeria. This study was undertaken to develop an acceptable chin-chin from orange fleshed sweet potato (OFSP) and red bambara groundnut (RBG) flours. Orange fleshed sweet potato contain beta carotene which is a precursor of vitamin A. Red bambara groundnut have potential to supply high protein to food products. The OFSP and RBG flours were blended in ratios 60:40, 50:50, 40:60, and 30:70, respectively.

Teacher thought and action are variables that have been considered as explanatory of the teaching - learning in the classroom. At work the theories of action of educators about the personal and social development in preschool children are described and exposed the relationship between their theories and theories in use is analyzed. He was approached from a qualitative perspective, using the technique of case study. We worked with three educators two kindergartens in Mexico City.

The outbreak of coronavirus (COVID 19) has led to the death of over 400,000 all over globe and over 7 million of confirmed cases within five months and exact drug for immunization and cure has not been obtained but preventive measure can be taken. One of such preventive measures involved washing of hand regularly, especially in the public like schools, shopping centers, religion centers, offices, bankse.t.c need to have automatic hand washing dispenser. In this work a low cost automatic hand washing dispenser was developed.

The history of India spans over more than 2000 years. It has different states each with its own distinctive social and cultural character. The western regions of India have a hot and semi- arid climate with irregular rainfall. There was always a need to collect water of monsoon rains to utilize it during the dry months of the year. That is how the step-wells came into existence and India is a home to hundreds of them.
