Assist. Prof. Dr. Sedik Ahmed Kasim (lecturer in the Department of Sustainable Development-ERC) presented a lecture on Tuesday, 28/1/2020 at 12:00 entitled “Alternatives and Environmental Significance”. The lecturer stated that the appearance of the European Renaissance in the eighteenth century led to the generation of an industrial revolution, which reflected positively on the various sides of life (economic, social, etc.). At the same time, it reflected negatively on the environment side in terms of the emergence of environmental pollution as a global phenomenon, which directly affected the essential requirements of life in water, air and food, as well as changing the environmental balance and consequently a great damage in the agricultural area in conjunction with a real problem in terms of the defect in providing the necessary need for food products occurred. Therefore, it was necessary to search for alternatives to avoid this problem and moving toward the chemical industry in terms of the use of chemical fertilizers. The excessive use of them led to the deterioration of nutritional value of agricultural crops and the direct impact on the environmental balance of natural elements.

The technical progress has contributed to development of the concept "protected agriculture", which means the provision of agricultural crops throughout the year. Apparently, this concept indicates that there are positive benefits from its use, but there is a concern about the possibility of a direct relationship in terms of the effect between this concept and climate changes. The use of protected agriculture and greenhouses may effectively limit the process of absorbing the significant amounts of carbon dioxide from the atmosphere by plants under the photosynthesis process.

The lecturer recommended that searching for the environmentally friendly alternatives should be carried out by encouraging scientific research and using modern technologies in this field such as renewable energies and adopting modern irrigation methods.

Assist. Prof. Dr. Saadi M. D. Al-Nuzal (lecturer in the Department of Environmental Pollution-ERC) presented a lecture on Tuesday, 21/1/2020 at 12:00 entitled “Scientific Promotions at UOT in Accordance with the Instructions for Promotions No. 167 of 2017”. The lecturer clarified the technical details relating to these instructions, which are an essential prerequisite for obtaining the scientific promotion for the university academic staff in terms of their relationship in two significant sides. The first side relates to scientific outputs in terms of publishing research in well-qualified international journals, authoring scientific books, submitting patents, and effectively participating in scientific conferences. While for the second side, which is organizational for these scientific outputs, according to Tables No. 1 and 2.

The lecturer recommended that the need to deal with these instructions seriously by university academic staff who are holding various scientific titles and prepare the required materials for scientific promotion early to ensure their applications for promotion are properly processed. Getting the scientific promotions according to these instructions will play a vital role in progressing the Iraqi universities within the international rankings.

Mrs. Afaf AL-Rahman Ayoub-lecturer in the Department of Environmental Technology-ERC presented a lecture on Tuesday, 14/1/2020 at 12:00 entitled “Keto Diet-Its Benefits and Harms”. The lecturer stated that the keto diet is a diet system with low in carbohydrates, medium in protein and high in fat in which the body are being generally changed to a fat burning machine. The name of this system is derived from the ketone molecules that are stored in the liver as an alternative energy source when there is no primary energy source, glucose and insulin. This diet consists of three stages:

  1. The no-carbohydrate stage where the amount of carbohydrates does not exceed 20 g.
  2. Moderate carbohydrate stage where the amount of carbohydrates is between 20-50 g.
  3. The phase of carbohydrates released where the amount of carbohydrates is between 50-100 g/day.

Despite the recent spread of this system in our society where many studies have shown the benefit of this type of diet to lose weight effectively without feeling hungry, there are many health warnings due to its use as it is not recommended to follow it without consulting a doctor. Symptoms of the keto-floating disease include feelings of low body energy, sleep disturbances, impaired cognitive function, digestive disorders and an inability to exercise.

Dr. Mukheled Amer Hussien-lecturer in the Department of Environmental Pollution-ERC presented a lecture on Tuesday, 31/12/2019 at 12:00 entitled “Integrated Technology consisting of Advanced Oxidation Process and Membrane Separation Process for the Treatment of Industrial Wastewater”. The lecturer stated that there are many chemical organic pollutants in the industrial wastewater effluents that have a high ability to resist the conventional wastewater treatment processes like (biological wastewater treatment- the most environmentally friendly and cheapest method) and thus, these pollutants can flow through those streams to be discharged into the environment. As a consequence, the environmental concern has been risen. Advanced oxidation processes (AOPs) as essential solution for this problem where they produce free hydroxyl radicals having a high oxidation potential to oxidize (degrade) the refractory organic pollutants either partially to form short-chain acids that are amenable to biological treatment or totally to CO2, H2O and inorganic ions as final compounds. In real applications, there are many advanced oxidation processes which each of them having advantages and disadvantages in performance. Generally, the performance of these processes can be improved when connected with membrane separation processes to produce the integrated technologies where these technologies are able to improve the quality of wastewater effluent to be in agreement with environmental standards. 

An integrated technology consisting of heterogenous and homogeneous photocatalysis with membrane separation process was selected as a case study to oxidize (degrade) a selected industrial model like polyethylene glycol-a common pollutant in conventional wastewater effluent streams into the environment due to several industrial applications like food, cosmetic, pharmaceutical, lubricants, antifreeze and etc. Experimental results of this technology proved that this pollutant was primarily degraded to different types of short-chain acids that can be used later due to their economic considerations or biologically treated.
