Mercury pollution and its impact on aquatic organisms
...Show More Authors

Mercury is a heavy metal that is extremely toxic. There are three types of it: inorganic, organic, and elemental. Mercury in all its forms has been shown to have harmful effects on living things. It can multiply its concentration from lower to higher trophic levels and accumulate in the body's various tissues. Aquatic organisms bodies have been exposed to mercury mostly through various human activities. The largest source of mercury pollution in the air is thermal power plants that mostly use coal as fuel. It is carried to a body of water after being deposited on the ground surface from the air. The way it enters the food chain is through aquatic plants and animals. Mercury accumulations in the kidney, liver, gills, or gonadal tissues of species that are readily exposed and ingested in aquatic organisms environments. There are possible effects of mercury exposure at both acute and long-term levels. The length of time, the mode of exposure, and the dosage all affect how harmful a substance is. The current study provides information about the harmful effects of mercury in aquatic organisms environments. Even though significant mitigation measures and recommendations were implemented, this assessment provides a comprehensive account of mercury sources and emissions, as well as their destiny and movement across the various environmental compartments. Because of the existing mercury emissions and stability, eating fish still poses a major risk. Aquatic life may be toxically affected by mercury pollution in freshwater environments. Through the food chain, mercury buildup in aquatic organisms can also endanger human health. Aquatic creatures include macroinvertebrates and fish. which people ingest and put their health at serious risk. The effect of mercury on hydrocarbons and how it enters the food chain to reach humans has been identified.

Impact of context in determining the morphological semantics in the Diwan of Abi Al-Aswad Al- Dau’ali
...Show More Authors

Context has a significant impact on the interpretation of Qur'anic and literary texts, especially in ancient Arabic poetry since that language is no longer considered as a contemporary understandable language. Hence this research is entitled: (the impact of context on the morphological semantics in the Diwan of Abi Al-Aswad Al-Dau’ali) and the morphological meanings indicated by the morphological formula which lack the combination of other contextual clues. The researcher depended on the analytical approach to show the impact of pairing occurring between the contextual elements on determining the morphological meaning.
The most important findings reached at:
1- Context has a great impact in dispelling the possibilities arising fr

The impact of the US military variable in reality Security in the Arab Gulf region after 2003
...Show More Authors

The military presence in the Gulf region after the British withdrawal from it in 1971 was one of the most important pillars of the American strategy to climb the ladder of global leadership, as the geostrategic features that the region enjoyed provided factors of controlling energy sources and global trade routes. The United States of America guarantees Western Europe and Japan the process of access to energy sources and the exclusion of its opponents from the region, especially the Soviet Union, and the growing American military presence in the Gulf after the invasion of Iraq in 2003. On the other hand, the region experiences many contradictions, some of which threaten its security, such as the exacerbation of disputes between its count

Variables Impact Spatial Change for Rural Settlement in Al-Hammer Marsh-Land in Governorate of Thi-Quar
...Show More Authors

During the period 1970-2006 the Marshes-land region was exposed to several change into many sides of vanishing steeling and growth as follow :
1- Drying this region after 1991,and re-flooded again during 2003. Many other large Marsh-land, like al-Hawaisa was dried by cutting off inlet-water fed from Iran sources .As asqunance there are transferred to different kinds of swamps ,followed by major change in the structure of the region as the rural settlement concerned. Rural settlement in this area starts new push of migration. The research did not take that in consideration in this thesis because some others took it in details in some thesis and researches. The situation of Marsh-land is getting anew face after those major changes which

On-Board Digital Twin Based on Impedance and Model Predictive Control for Aerial Robot Grasping
...Show More Authors

Aerial manipulation of objects has a number of advantages as it is not limited by the morphology of the terrain. One of the main problems of the aerial payload process is the lack of real-time prediction of the interaction between the gripper of the aerial robot and the payload. This paper introduces a digital twin (DT) approach based on impedance control of the aerial payload transmission process. The impedance control technique is implemented to develop the target impedance based on emerging the mass of the payload and the model of the gripper fingers. Tracking the position of the interactional point between the fingers of gripper and payload, inside the impedance control, is achieved using model predictive control (MPD) approach.
