The measurement of solar irradiation is still a necessary basis for planning the installation of photovoltaic parks and concentrating solar power systems. The meteorological stations for the measurement of the solar flux at any point of the earth’s surface are still insufficient worldwide;moreover, these measurements on the ground are expensive, and rare. To overcome this shortcoming, the exploitation of images from the European meteorological satellites of the second generation MSG is a reliable solution to estimate the global horizontal irradiance GHI on the ground with a good spatial and temporal coverage. Since 2004, the new generation MSG satellites provide images of Africa and Europe every 15 minutes with a spatial resolution of about 1 km × 1 km at the sub-satellite point. The objective of this work was to apply the Brazil-SR method to evaluate the global horizontal GHI irradiance for the entire Moroccan national territory from the European Meteosat Second Generation MSG satellite images. This bibliographic review also exposed the standard model of calculation of GHI in clear sky by exploiting the terrestrial meteorological measurements.

磷石膏(PG)是磷酸生产工业的主要副产物,被认为是稀土元素(REEs)最重要的二次来源之一。本研究重点是回收PG中存在的REEs和残留的磷酸盐的同时,保留CaSO_(4),以用于其他各种应用。这些成果是采用柠檬酸浸出工艺实现的。研究了几个参数对柠檬酸浸出回收稀土的影响,包括浸泡时间、浸泡温度、柠檬酸浓度、固液比以及柠檬酸浸出溶液在进一步的稀土溶解实验中的循环利用。最佳操作条件为室温浸泡时间14 d,柠檬酸浓度为7.5%,固液比为1/5。优化条件下稀土的溶解效率为79.57%。将不同的新鲜PG样品与相同的柠檬酸溶液依次混合浸泡4个阶段,在最佳浸泡条件下,稀土的累积溶解效率为64.7%。采用Dowex 50X8树脂从柠檬酸溶液中回收稀土,萃取效率为96%。溶解动力学证明了稀土的伪一级性质、溶解过程为可逆反应,存在两个活化能。

Southern Red Sea flooding is common. Assessing flood-prone development risks helps decrease life and property threats. It tries to improve flood awareness and advocate property owner steps to lessen risk. DEMs and topography data were analyzed by RS and GIS. Fifth-through seventh-order rivers were studied. Morphometric analysis assessed the area’s flash flood danger. NEOM has 14 catchments. We determined each catchment’s area, perimeter, maximum length, total stream length, minimum and maximum elevations. It also uses remote sensing. It classifies Landsat 8 photos for land use and cover maps. Image categorization involves high-quality Landsat satellite images and secondary data, plus user experience and knowledge. This study used the wetness index, elevation, slope, stream power index, topographic roughness index, normalized difference vegetation index, sediment transport index, stream order, flow accumulation, and geological formation. Analytic hierarchy considered all earlier criteria (AHP). The geometric consistency index GCI (0.15) and the consistency ratio CR (4.3%) are calculated. The study showed five degrees of flooding risk for Wadi Zawhi and four for Wadi Surr, from very high to very low. 9.16% of Wadi Surr is vulnerable to very high flooding, 50% to high flooding, 40% to low flooding, and 0.3% to very low flooding. Wadi Zawhi’s flood risk is 0.23% high, moderate, low, or extremely low. They’re in Wadi Surr and Wadi Zawhi. Flood mapping helps prepare for emergencies. Flood-prone areas should prioritize resilience.

Walterinnesia aegyptia is one of the most venomous snakes belonging to the family elapidae found in the Middle East and Africa. In addition to its ecological importance, it is accused of millions of deaths due to snakebites. Because molecular identification of snakes is crucial for the antivenom drug industry, mitochondrial genes are used to identify, characterize, and infer genetic diversity among different venomous snake species. Data of Walterinnesia collected from samples across Saudi Arabia were compared based on the mitochondrial 16S and 12S rRNA sequences with other elapidae related taxa to assess the phylogenetic relationship. The phylogenetic analysis strongly supports the monophyly of the genus Walterinnesia based on two genes that represent different species of elapidae. In addition, a close relationship between Walterinnesia aegyptia and W. morgani was found. Our molecular data showed that W. morgani from Riyadh, Saudi Arabia, is nearly genetically identical (D = 0) with W. aegyptia from Ha’il and Riyadh, Saudi Arabia, and Sinai, Egypt. Further study is required based on more material and detailed morphological and genetic analysis.
