As part of the cultural season of the Environmental Research Center in Cairo Assistant Professor Dr. Salih Abdul-Redha Al-Salih lecture entitled "Hemorrhagic fever" begins on Wednesday, 10/4/2019, where the lecture summarized the following:
Viral Hemorrhagic Fever (VHF) is a group of infectious diseases that infect human and causes disability of the natural coagulation lead to heavy bleeding at subcutaneous, eyes, ears and maybe systematic, many types of viruses causes (VHF) like Ebola virus, Dengue fever and yellow fever. Human infection causes by contacting with the infected animals or by vector arthropods like mosquito or tick which is carrying the virus body, The real threat to virus diseases come from lack of true treatment and the vaccination is not permanent, The best way to avoid infection is to prevent it by avoiding infested places, eating and drinking safe food and water, control rodents and insects, take the vaccine and check before traveling outside the country.
As part of the cultural season of the Environmental Research Center, Asst. Lecturer Ahmed Safaa Abdel-Hassan delivered a lecture entitled "Modern methods in the treatment of corrosion of oil pipelines" on Wednesday 4/4/2019, where the lecture summarized the following:
Corrosion is the deterioration of the properties of the material or metal as a result of a chemical or chemical reaction with its environment, which is called corrosion, not as a result of a mechanical process such as friction in machines.
Corrosion classification:
First in terms of temperature is classified into:
- Corrosion due to high heat.
Corrosion due to low heat.
Second in terms of surrounding environment, it is classified into:
1.Dry erosion: occurs as a result of a direct chemical reaction in the sense that there is no transmission of the cargo, and the corrosion products are either volatile products, the surface is film free or precipitated resulting in surface buildup. One of the benefits of this type is that it protects the surface from further corrosion.
2.Wet corrosion: According to the label, it is necessary to have liquids or moisture to cause wet erosion
Third In terms of places of erosion
In this case, corrosion is divided into:
1. Uniform uniform corrosion occurs at the entire corrosive surface and the solution of this condition is the internal corrosion-resistant lining known as: corrosion-inhibiting substance (CIS)
2. Concentrated or concentrated corrosion, in this case concentrated in specific areas at the bottom of the tube. This condition requires the replacement of the sections due to the concentration of the corrosion intensity.
Methods used to combat erosion:
1- Cathodic protection to reduce and reduce corrosion in the external areas of the tube to ensure that the flow is free of moisture and a small proportion of oxygen and hydrogen and reduce the quantities of gases associated with crude oil, especially CO2.
2- Smart Pigging
The most important steps to reduce corrosion in the pipes are the use of intelligent skimming processes, which is the most appropriate way to clean the internal surface of the pipes and disposal of unwanted plankton and also the early identification of the places of erosion. Smart skimming processes determine the eroded areas in terms of location and depth eroded and the size and size The eroded area gives us a full conception of the economic feasibility of keeping that damaged part or replacing it.
As part of the cultural season of the Environmental Research Center / University of Technology, Assist. Prof. Dr. Saadi Mohammed Dhaher delivered a lecture titled on (chemistry of global warming) on Wednesday, 27/3/2019, where the lecture summarized the following:
Scientific studies revealed that global warming over the past two centuries is the result of the accumulation of greenhouse gases. But there is no conclusive evidence that climate changes in this era are not natural. The climate has become warmer due to the internal anarchic dynamics in the Earth-atmosphere system (ie no external influence) as well as the direct increase in solar energy production. When studying the possibility of blaming greenhouse gases, spectral calculations show that these gases cannot exceed their effects. Water covers three quarters of the earth is very effective, a steady state since the dawn of history and combined greenhouse gases cannot have this effect. The data also show that absorption of solar radiation is mainly due to water vapor in the atmosphere. The rest of the gas components exist in small amounts that do not qualify them to be the main factor in global warming. From the above it turns out that the rise of carbon dioxide in the atmosphere is not the main culprit in raising the degree of air drag.
On the other hand, the phenomenon of global dimming which alert scientists since 1950 can be the reason. The extent of blackout varies depending on location, but total solar radiation on the Earth's surface decreased by 4% in a period spanning three decades from 1960 to 1990. But after 1990, the value of solar radiation began to increase slightly, with the exception of 1991, when the eruption of Mount Benato. Global dimming is believed to have resulted from an increased concentration of pollutants in the atmosphere due to human activity. The tendency to move from global dimming to global lighting is the result of decreasing atmospheric haze. Global dimming has been associated with the water cycle, where evaporation rate is lower and may be associated with decreased precipitation in other regions. Global blackout also creates a cooling effect of the Earth, leading to partial inhibition of global warming. That the increase in the presence of carbon black minutes and thus significantly increase global dimming could be attributed to an increase due to humanitarian activities associated with the inefficient combustion of oil derivatives and coal as well as volcanic eruptions and forest fires. The deposition of carbon black minutes on the northern and southern poles may be the main reason behind the reduction of the reflection of an important part of the solar radiation outside the atmosphere and thus raise the temperature. The equation below can be formulated to justify the rise or fall of atmospheric temperature in an approximate mathematical manner:
CBtotal = CBairborne + CBpoles
Within the activities of the Environmental Research Center for the academic year 2019, the Soil and Water Laboratory at the Environmental Pollution Department received a group of graduate students from Baghdad University / College of Science for Girls / Biology Department on Tuesday 19/3/2019. , And the teacher Rana Riad Khalil, supervisor of the laboratory and with the help of chemist Ahmed Alwan, to provide a detailed explanation of the devices and measurements to assess the quality of water.
