Dr. Eman Othman Al-Toumi has been working at the University of Tripoli as an assistant lecturer since 04-05-2008 and has many scientific publications in her field of specialization. She was assigned to teach courses in the field of agricultural engineering:

1. Agricultural pumps.
2. Engineering drawing 1.
3. Engineering drawing 2.
4. General machinery and tractors.
5. General area and buildings.

      The courses were taught during the years from 2008 to 2019 during the fall and spring semesters, respectively. The courses performed their theoretical aspect with specific teaching hours set by the college and performed the practical aspect for each course. She participated in the programs for downloading the courses, whether manually or through the electronic system at the college throughout the years of teaching. Students were supervised in graduation projects for the bachelor's stage throughout the years of direct attendance.

Careers

She obtained her bachelor's degree from the University of Tripoli during the fall semester of 1998 from the Department of Agricultural Engineering, Faculty of Agriculture. She was appointed as a teaching assistant in the department in 2000 and worked for two years in the department. She was nominated for a scholarship in 2003 to study for a master's degree in engineering sciences in the Arab Republic of Egypt, Cairo University. She obtained the degree in 2008 and worked there from 2008 to 2019. She was assigned as a study and examination coordinator at the college from 2017 to 2019. She was nominated for a scholarship to obtain a doctorate degree in 2019 and obtained the degree in 2023.

Research Interests

The research was conducted in the field of irrigation under the title

1. (The effect of different fertilizer injection devices on the efficiency of water and fertilizer distribution by pressure in the drip irrigation system).

The research aims to compare different fertilizer injection methods during irrigation with Palt-in and Palt-on type points in the irrigation line with three different side lengths in the drip irrigation system and to discover the best method of fertilizer injection during irrigation. The results led to the efficiency of fertilizer distribution by the hydraulic device by 96% compared to the venturi device 75% compared to 82% for the electric one. As for the hose lengths for the drip irrigation network, it was recommended to use the regular fertilizer tank and it was 40 meters for the hose and 16 mm and the Palt-in points discharging 4 liters/hour and the distance between the points is 50 cm. As for the electric fertilizer, it is recommended to use it to inject fertilizer for hose lengths of 60 meters, and as for the venturi device, it is recommended to use it in branch lengths of 40, 20 meters.

2. (Improving the performance of an indirect solar dryer using moisture absorbing materials).

The creation of an innovative indirect solar dryer to increase the efficiency of its thermal performance, as it can benefit from the hot air coming out of the dryer by re-entering it into the dryer in a closed system, while extracting all the moisture present in it by passing it over pads of silica gel particles as a moisture absorbing material, and comparing it with another indirect solar dryer similar in dimensions and a direct solar dryer, and their thermal performance efficiency was tested. The drying of tomato slices and basil leaves was also tested and compared with another direct solar dryer, and the moisture content (wet basis and dry basis), moisture content, drying rate, evaporation rate, drying rate, and drying constant were estimated. Some quality specifications of basil leaves (volatile oil) and dried tomato slices and their quality specifications (phenols, lycopene, and peptides) were also determined under solar drying conditions in the three different dryers. The results showed the developer's success in improving the thermal performance efficiency and reducing the drying time of the tomato slices product with high moisture content (92%) and long drying hours by direct solar drying.

3. Agricultural Products Packaging Engineering

Vegetables, fruits and their products are a major source of fiber, complex carbohydrates, vitamins and antioxidants. They lower cholesterol levels, reduce the risk of heart disease and protect humans from modern diseases, especially cancers. They are also considered one of the most important defenses that work to reduce the percentage of toxins in the blood and help the body get rid of accumulated fats and toxins.

Packaging is considered one of the important and main steps in the field of food and dairy industries and agricultural products trading, as the packaging represents a necessity to maintain the quality of the product and deliver it to the consumer in a good and safe way, while packaging is covering a group of fruits with different types of covers in order to protect them from water loss and reduce their breathing rate, which maintains their fresh appearance. Wrapping the fruits also reduces the friction of the fruits with the walls of the packages. Recently, studies have begun on packaging fruits with artificial and natural films, namely chitosan films and lignin films, which work to retain the moisture that is absorbed on the surfaces of fruits and vegetables during storage, thus not creating suitable environmental conditions for microorganisms. This also works to reduce the concentration of the resulting gases and their effect on ripening.
