Biologie Résumé :
Precipitation variability is one of the most important elements for climate and hydrometeorological studies. North African countries, and specifically Algeria, have an increased sensitivity to climate variability, particularly the precipitation, due to its effect on economic, social and demographic structure. In the present study, the main objective is to contribute to a better understanding of the spatial and temporal variability of rainfall for 22 meteorological stations distributed in Northeastern Algeria for the period1978-2010. The results showed that, spatially, precipitation decreases from North to South and from
East to West. The application of the Mann–Kendall test to the time series data showed that for annual precipitation, no station showed statistically significant trends, unlike the number of rainy days, where there was a significant negative trend in four stations (Jijel, Constantine, Oum El Bouaghi and Tébessa). For the monthly time series, significant positive trends were observed during the months of September in the coastal stations and July for the plateaus and southern Saharan Atlas stations, while significant negative trends were recorded during the months of February and March for the stations of the extreme
East in the study area. The regionalization of stations in northeastern Algeria based on inter-annual variability through Principal Component Analysis (PCA) and Hierarchical Ascending Classification
(HAC) has identified five distinct groups of stations for the period 1978-2010. These results revealed that for the period analyzed, there was no significant climate change in northeastern Algeria but there is a seasonal delay.

UniversitaireIndex. décimale : 020 علم المكتبات و المعلومات Résumé : This study aims to promote the many benefits of printed and electronic paper, and its role in the formation of the university student, but also targets the knowledge of different types, forms, benefits and services that can provide the library university to meet the needs of students as information quality to study or to make their presentations and science projects and grow, so it refers to the interest of university libraries by making a budget for an acquisition of information sources, periodicals, databases and connect computers to the Internet. The results are obtained based on a field survey and data analysis, interpretations and comments, we noticed a growing interest for the student academic books, periodicals, dissertations, theses and use of the computer and Internet in his studies and science projects, and even if the use of paper remains the most important. The facts presented in this work are the result of the study in the libraries of the faculties of humanities and social sciences, engineering, sciences, humanities and languages, economics and management, law and political science. The results showed that the student is facing many ifficulties in his search for documentation, regardless of its type, paper or electronic, and it inhibits its tendency to read and deprives more than able to make the library and the Internet, because of his ignorance of recovery tools that are at the library as well as that of the research data. Despite the services provided by the university library, does that they are below the level required to meet the requirements of the student. We conclude this study by proposing that we think may give more consideration to one side to the sources of information as well as its diversity, and another side to the initiation of students to use it, and motivate to consult with more regularity in order to better exploit in the studies, research and Job.
