The Women Empowerment Unit at the Presidency of our Northern Technical University celebrates its first anniversary
2022-10-10
The Women Empowerment Committee at Kirkuk Technical College of Engineering, in cooperation with the Department of Computer Technology Engineering, holds a symposium entitled “Psychological Empowerment of Women Leaders”
2022-10-11Kirkuk Health and Medical Technical College hold a course entitled “Bacteria that are beneficial and harmful to humans and other uses for them”…
Under the patronage of the President of the Northern Technical University, Prof. Dr. Alia Abbas Ali Al-Attar, and under the supervision of Prof. Dr. Muhammad Yawuz Nour El-Din, Dean of the Health and Medical Technical College / Kirkuk, the Industrial College Techniques Department organized a scientific course entitled “Bacteria beneficial and harmful to humans and their other uses.”
The lecture was given by:
- Assistant Professor Dr. Siham Shakur Obaid
- The teacher, Dr. Asmaa Muhammad Suleiman
- The teacher, Dr. Ibtisam Abbas Majthab
The course dealt with the nature of bacteria, which are very delicate living organisms, not classified as plants or even animals, but rather they belong to a group of their own.
The session showed that bacteria are micro-organisms consisting of only one cell, usually several micrometers in length, and they are present together in millions, so one gram of soil contains approximately 40 million bacterial cells.
Whereas one milliliter of fresh water may contain about one million bacterial cells, Earth contains at least five nil billion bacteria.
The course aimed to clarify the locations of bacteria, namely:
- Soil and water.
- Radioactive waste.
- Plants and animals.
- The depths of the earth’s crust.
- Organic matter.
- Arctic ice and avalanches.
- Stratosphere.
- Deep ocean.
Of course, bacteria are not found in these places only, but specialists in bacteriology indicate that they are found almost everywhere except for the places and areas that humans sterilize, even those places with very high or low temperatures or that contain toxic chemicals, so you can find bacteria in them.
The session came out with several recommendations that explained the existence of several ways that enable bacteria to feed themselves:
- Heterotrophs: That is, they feed on other living organisms, and some types of bacteria kill the organism they feed on, while others help them.
- Autotrophs: That is, this type of bacteria makes its food, and this is done in two ways:
Photosynthesis, in which sunlight, CO2, and water are used to make food for bacteria.
Chemosynthesis, where bacteria use carbon dioxide, water, and certain chemicals such as ammonia to make their food.
