Evaluation of renewable energies production potential in the Middle East:confronting the world’s energy crisis

Oil and fossil fuels,the main source of energy in the Middle East have obviously the most destructive effects on the environment and public health.The developed countries of the Middle East are faced with the crisis and energy security.This paper is about evaluating the energy demand/consumption in the Middle East.First,the position of energy consumption in the world and the Middle East is discussed.Next,the evaluation of the current potential of clean energy production from renewable energies is explained.Finally,according to related maps,charts and information presented for the condition of renewable energy which has been approved by the countries of the Middle East,the greatest places in some countries of this region are introduced and discussed.

The Effects of a Novel Multicomponent Transition Metal Dichalcogenide on Nervous System Regeneration

In regenerative medicine,a scaffold is needed to provide physical support for the growth of cells at the injury site.Carbon composites are also widely used in biomedicine.This research aimed to see if(MoWCu)S/rGO could be used in peripheral and central neural regeneration as a carbon-based nanomaterial.This material was created using a one-step hydrothermal process.We used Scanning Electron Microscopy with Energy Dispersive X-ray analysis(SEM–EDX),X-ray diffraction,and Field-Emission Scanning Electron Microscopy(FE-SEM)to describe it.The researchers used animal models of spinal cord injury and sciatic nerve injury to assess its effect as a scaffold of anti-inflammatory and electrical conductivity.The Basso Beattie Bresnahan locomotor rating scale and von Frey Filament were used to assess neuronal function after(MoWCu)S/rGO transplantation.In addition,the expression of p75 NTR and neurotrophic factors(BDNF,NT3,and NGF)mRNA in the experimental rats nerve was compared to the normal ones using Real-Time RT-qPCR.In the experimental groups,the use of(MoWCu)S/rGO resulted in a significant increase in neurotrophic factor gene expression,while p75 NTR was inversely decreased.In conclusion,we found that the nerve regeneration activity of the(MoWCu)S/rGO scaffold in rat models significantly increased motor function recovery in the treated groups.Furthermore,the current study explained the response of this composite to inflammatory neurodegenerative diseases.(MoWCu)S incorporation in graphene is thought to have excellent properties and may be used in regenerative medicine.
