Expansive soils are found in many parts of the world that especially arid and semi-arid regions. They have caused several damages lightweight structures for decades. For this reason, a more suitable foundation type should be selected designed built on these soils. example, application belled shaft at expansive soil layer is preferable method practice. However, one worst cases design accepted sw...

The commercial exploitation of guinea fowl (Numidia meleagris) is a viable alternative for small rural properties in arid and semi-arid regions, as they are rustic birds capable withstanding the climatic adversities these regions. objective this study was to evaluate pupillary temperature, smaller diameter, larger diameter pupil area housed controlled environment, under two air temperatures: 26...

The arid zones of the world are all characterized by a large deficit of rainfall in relation to the potential evapotranspiration. Their distribution around the world is governed by the interaction of global atmospheric circulation patterns, the distribution of land and sea, and local topography. Countries that have substantial areas with arid conditions belong to very different groups in terms ...

Since the late 1970s, Southern Hemisphere semi-arid regions such as southern-coastal Chile, southern Africa, and southeastern Australia have experienced a drying trend in austral autumn, predominantly during April and May. The rainfall reduction coincides with a poleward expansion of the tropical belt and subtropical dry zone by around 2°-3° in the same season. This has raised questions as to w...

Lake Woods is a large freshwater body on the northern edge of Australia’s arid zone where research since late 1960s has suggested Pleistocene, later Holocene, and recent human occupations....

The current spread of zoonotic visceral leishmaniasis (ZVL) throughout arid areas of Central Tunisia is a major public health concern. The main objective of this study is to investigate whether the development of irrigation in arid bio-geographical areas in Central Tunisia have led to the establishment of a stable cycle involving sand flies of the subgenus Larroussius and Leishmania infantum, a...
