L'objectif de cette étude est de compléter les résultats déjà obtenus au Maroc oriental, dans la zone Bouarfa - Chott Tigri, sur le potentiel du GPS (Global Positioning System) pour la surveillance ...du déplacement des dunes. Les mesures, effectuées une fois par an de 2013 à 2023, ont permis de déterminer les évolutions de quatre petites dunes : déplacements dans différentes directions, extensions ou rétractations, engraissements ou dégraissements. Les résultats obtenus montrent l'intérêt du GPS ainsi que ses limites pour les études de ce type.
The aim of this study is to add to the results already obtained in eastern Morocco, in the Bouarfa - Chott Tigri area, on the potential of GPS (Global Positioning System) to follow the movement of ...dunes. The measurements, carried out once a year from 2013 to 2023, were used to determine changes in four small dunes: movement in different directions, extension or retraction, fattening or degradation. The results obtained demonstrate the value of GPS as well as its limitations for studies of this type.Traduction réalisée par DeepL
Serum samples of 11 Bengal tigers (Panthera tigris tigris) from Chitwan National Park in Nepal, collected between 2011–17, were evaluated for the presence of antibodies to eight diseases commonly ...investigated in large felids. This initial serologic survey was done to establish baseline information to understand the exposure of Nepal's free-ranging tiger population to these diseases. Tiger serum samples collected opportunistically during encounters such as translocation, human conflict, and injury were placed in cold storage for later use. Frozen serum samples were assessed for feline coronavirus (FCoV), feline immunodeficiency virus, feline leukemia virus, feline herpesvirus (FHV), canine distemper virus, canine parvovirus-2 (CPV-2), leptospirosis (LEP; seven serovars), and toxoplasmosis (TOX). Six tigers were found to be positive for LEP, eight for CPV-2, five for FHV, one for FCoV, and 10 for TOX. Tigers, like other wild felids, have been exposed to these common pathogens, but further research is needed to determine the significance of these pathogens to the Nepali population.
In a context of unequal distribution of water resources, population growth and economic development, water increasingly plays the role of strategic variable able to alter the geopolitical balance ...especially in those areas where water sources are shared by several countries. This article aims to analyze the Tigris-Euphrates basin dispute where the historical contention over the management and the exploitation of water shared by Turkey, Syria and Iraq is exacerbated by the effect of climate change and the entry of new players in the control of the resource. The increased frequency and intensity of drought amplifies the gap between water supply and demand while the new hydrological order designed by the expansion of the Islamic State, restricts the access to the resource by the most vulnerable populations. Particularly disadvantaged are women who are daily entrusted with the daunting charge of scarce water resources management and allocation between different uses. The control by the Islamic State of large dams along the course of the two rivers, the use of water as an instrument of pressure and the resulting deterioration in the quality and quantity of the resource, not only increase the amount of work that women have to spend for the collection and distribution of water but threaten food security and the health of them and of their families.
The dramatic growth of the private small-medium enterprises (SMEs) in China can be deemed as one of the driving forces of the successful economic change of that country. The high growth rate in ...output, employment, investment and productivity reflects the dynamism of this sector: its share in GDP is now over 33%. Recent surveys, however, have revealed that most of the private SMEs are still constrained by the institutional framework (they have been recognized by law in 1998) as well as by their small scale, technical inefficiency, opaque corporate governance, lacking investments. These factors do affect, of course, private enterprises'market strategies and their competitiveness in the globalised economy. During the last years, Chinese government has often declared its pledge to support the business and technological improvement of private enterprises both by fostering the linkages between them and the large corporations (domestic and multinational ones) and implementing pro- active policies. This task, however, is not easy to carry out successfully. Many Chinese economists as well as policymakers, are, in fact, raising some doubts on the role of these small, often tiny, enterprises in the growth strategy of their country. Notwithstanding small scale enterprises'ability to generate employment and income, in developing countries they are often associated with environmental pollution, poor quality of products, negligence toward workers'rights, tax evasion. The surveys carried out in China do confirm the «informality» of this sector and its scarce propensity to the corporate social responsibility. This picture contrasts with the project of modernization, which, according to the latest formulations by the Chinese communist leadership, means a pattern of growth relied on the quality (no longer on quantity) of production, life and natural environment. That means, in the words utilized by the Chinese policymakers, the transformation of a «large» manufacturing country into a «strong» manufacturing country.
