 In light of the importance of strengthening the basic role of universities in building the society in all its developmental fields, including health, economic, scientific and cultural, and to address the problems that confront our daily life and in a scientific and technical manner aimed at proposing successful solutions that serve the community, Environment for the Middle Region The symposium entitled "Improving the Environmental Reality of the Brick Industry" was held on Thursday 18 April 2019 at the Green Hall in the center.

The seminar included four working papers as follows:

The first working paper (the environmental reality of the brick factories in Iraq) presented by the former chief architect Eng. Thabet Khalil, Assistant Director General of the Department of Protection and Improvement of the Environment of the Middle.

The second working paper (the brick industry in Iraq between Iraq and ambition), presented by Mohannsen President Aked Ali Akhtar Ahmed / consultant engineer in the Directorate of the mark for industrial development.

The third working paper (Brick industry in the public sector / problems and solutions and the treatment of industrial claims) Chief Engineer Majed Jassim Hamoudi and the chief engineer of the oldest Ghani Awad Hassan / General Company for Construction Industries.

The fourth working paper (Experiment of the operation of traditional brick factories using LPG), which was given by the assistant head of engineers Shaima Ahmed Issa from the gas filling company.

A lecture by Assistant Professor Dr. Amer Majid Al-Dabbagh / Machinery and Equipment Engineering / Technological College.

The symposium concluded with a number of recommendations that will be mentioned after being approved by the Board of Directors.

Assist. Prof. Dr. Saadi M. D. Al-Nuzal present a lecture entitled "Analytical Applications of Spectroscopy of Ultraviolet Radiation Absorption" on a number of graduate students PhD and MA in the laboratories of the Department of Environmental Pollution, ERC. The lecture included the theoretical basis of this technique and Lambert Bauer's law and its applications. It also included the description of components of the commercially available spectrophotometers and their types and how they are used for the quantitative analysis of many natural, industrial and medical materials and in academic studies. A laboratory demonstration was made of how to use this spectrophotometer to measure the spectrum of a certain known compounds and identify them by the wavelength of absorbed chromophoric groups and how to take the advantage of the molar absorptivity constant for each absorption peak in the compound.

As part of the cultural season of the Environmental Research Center,Lecturer Rana Riyad Khalil delivered a lecture entitled "The Fate and Effect of Detergents (Surfactants) in Tigris River within Baghdad City / Iraq" on Tuesday, 16/4/2019, where the lecture summarized the following:

The aim of this study is to determine the quantity and quality of surfactants (anionic (AS) and nonionic (NS)) in Tigris River and Al- Rustamiya wastewater treatment plant (RWWTP) (before and after treatment). Six sites were selected for this study and samples were collected from water, particulate, sediment and submerged plant in the river, while the treatment plant included water and particulate for the period from February 2017 to February 2018 and results were expressed as seasonally (wet and dry). Some physicochemical parameters are also measured at all sites per months. Two analytical methods were used photolab (PHD) and HPLC device for surfactants.

Also Person's correlation coefficient, Principle component analysis (PCA) and Factor analysis (FA) (multivariate statistical methods) were used as a tool to interpret the correlation between physicochemical parameters (for all six sites and two analytical methods) with surfactants.

From this study, the concentration of anionic and nonionic surfactants was in the following order: Particulate > Aquatic Plant > Sediment > Water. The RWWTP revealed its efficiency as treatment processes for anionic and nonionic surfactants where compared with permissible limits of use for irrigation purposes after treatment.

Lecture entitled "Hemorrhagic fever"

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.
