The major hot deserts of the world are located on the western coasts of continents between latitudes 15° and 30°N and S. as shown in Fig. 131. They include the Sahara Desert, the largest single stretch of desert, which is 3,200 miles from east to west and at least 1,000 miles wi...

When a solution in equilibrium with its environment has reached saturation, ifRHwill decrease, it will cause evaporation,supersaturationand precipitation. Some solutions reach this critical condition at ordinaryRH, and above the critical equilibrium levels ofRH, only the precipitated salts can be found...
and model testing (the remaining 25% data; R2 = 0.52–0.77) of the eight first-order model parameters except M2-k1ref, where a low R2was found in model testing (see Supplementary Table1). This indicates that RF could be used to reliably predict the decomposition kinetics parameters. T...
7. The Sahara is a highly diverse, albeit dry, region that has undergone major climatic changes since 10,000 B.C. (Official28-P3) 尽管干旱,撒哈拉的物种极其多样,并自公元前10,000年前开始已经历了数次重大气候变迁。 8. About 3,500 B.C., climatic conditions again deteriorated. (Official28-...

Leaf waxes from Northeast Africa are also likely transported by aeolian and fluvial pathways to the Mediterranean Sea, capturing the climate and environmental histories across biomes46covering the Ethiopian Highlands, the Nile River Valley, and the northeastern Saharan Desert ...

Viral communities and metagenomes in natural freshwater ecosystems have previously been described in various lakes and perennial ponds in Sahara. The study looking into freshwater RNA viruses suggested that the fresh- water lake ecosystems might serve repositories of pathogenic and non-pathogenic RNA ...
