An in vitro study of zinc effect on Trichomonas vaginalis isolated from infected women
Get PDFThe most common non-viral sexual transmission disease in humans, trichomoniasis, is caused by the protozoan parasite Trichomonas vaginalis (STD). Metronidazole is the most frequently recommended of the imidazole drugs used to treat trichomoniasis. In any case, these substances may result in undesired side effects and parasite resistance. As a result, this infection needs to be treated in a different way.
Aim: This study was designed to determine the relation between zinc intake and the Trichomonas vaginalis occurrence and also to find out the in vitro effect of zinc on T. vaginalis viability.
Methods: This study was carried out on 63 pregnant women whom attended (Azadi Teaching, Kirkuk General and Al-Nasr maternity) Hospitals from December 2021 till April 2022. Specimens of vaginal swabs and serum samples were obtained from all pregnant women. The swabs were first examined directly by normal saline on slide microscopically then inoculated onto Modified Diamond medium. Zinc levels and concentrations in the blood were assessed using serum. Result: T. vaginails was isolated from pregnant women. The overall prevalence among 63 examined samples were positive by direct microscopically and culture with a rate of 5(8%) while 58 (92%) were negative. The 1.5mg/ml zinc concentration was the most effective on T. vaginalis trophozoites number than other concentration of zinc. Conclusion: Zinc is a very important anti- T. vaginalis and can be used it as dilution washing for treatment process.

Starting Analysis of Squirrel Cage Induction Motors 1000 kW by Variable Frequency Drive in Power System, Case study: Tabriz Pump station
Get PDFIn petroleum industrial systems, analysis of power systems should be considered to exploit system reliability and prevent change in process performance during starting in equipment such as induction motors and industrial pumps. Medium-voltage induction motors are essential electrical machines in the oil, petrochemical, and process industries; therefore, the study of induction motors is an integral part of the analysis of power system. These motors are directly fed from the power grid and are exploited afterward. The starting current of induction motors is 5 to 7 times greater than the nominal current at the moment of starting until it reaches the nominal torque. This starting current will result in the motors and transformer and voltage drop in users' appliances connected to the electric grid to the extent that it might even cause a shutdown in the grid or not start the motor. It will also directly impact the power quality of the power system. For this reason, the starting voltage drop should not exceed 15% of the terminal voltage. In this paper, the starting of squirrel cage induction motors 1000kW by variable frequency drive in Tabriz pump station has been analysed by the ETAP 19.0.1 software

The rate of increase in fuel consumption between July and January was 14.2%, and the results also showed that the ratio of production to design capacity for January was the highest and amounted to 87%, and the highest efficiency reached 33%, while July was the lowest production rate in terms of design capacity, reaching 53% and efficiency of 29.8%
Influence of Micro-Controller-Based Single Axis Solar Tracker System on Solar Panel’s Performance: Case Study
Get PDFThere is governmental, academic, and business interest in new emerging renewable energy sources, such as solar energy. In particular, how and how much it produces energy and the environmental impact of these sources. To highly benefit from renewable energies, new methods should be utilized. In this paper, the Microcontroller Arduino Uno board has been used and programmed by Arduino software to build a system as a photo-sensor (Active) Single Axis Solar Tracker System (SASTS). The system was created using a solar panel, two Light Dependent Resistance (LDR) have been used on the two sides (north/south) of the photovoltaic (PV), and a servo motor is connected to the Uno board. The tracking system is constructed to procure the data using the Microcontroller Uno board and specially designed mechanical base. Based on the extracted results, the influence of the SASTS on increasing the solar panel performance is more evident than the outcome Maximum Power Point (MPP) of MATLAB Simulink. Continuously, the SASTS searches for the sun and its position in the sky and puts the PV direct to the sun. Significantly, the tracker system raises the power ratio of the PV. As a result, it significantly increases the solar panel's performance and increases by 55.2% on average during the daytime

Theoretical Study of Angiotensin Receptor Blockers Losartan Candesartan and Olmesartan and Their Suggested Metabolites
Get PDFThe activity of most Angiotensin Receptor Blockers (ARBs) is associated with the stability of their metabolites via a process termed bioactivation. A process called biotransformation forms these stable metabolites. The reactivity of these metabolite intermediates makes it difficult to observe and describe them directly. This work employed computational chemistry to investigate certain (ARBs) and their metabolites, as well as to forecast the most stable parent drugs. Homo values show that the (Losa.M) metabolite product is the lowest energy value for the Homo values, the thermodynamic energy, and the zero-point energy, in addition to having the lowest value of entropy associated with the rest of the other compounds. Losa. metabolism or biotransformation occurred via the oxidation of methanol moiety at position 5 of imidazole heterocyclic ring which produces the more stable carboxylic acid metabolite Losa M., this chemical reaction does not occur in the case of Olme and Cande. Olme and Cande undergo metabolism in another mechanism which is ester hydrolysis process, this reaction occurs rapidly and completely by GI esterases, the HOMO of these two drugs has low energy, (their HOMOs are not filled), and they are highly susceptible to reduction. and thus, this potential hydrolysis increased the drug metabolism and thus excretion.
 
Applications of the Biotechnology in Agriculture
Get PDFFarmers with 10,000 years of age have been cultivating,wild plants by selecting and breeding for certain features. In the twentieth century, breeding became difficult, as the characteristics of the breeders selected include increased yield, disease and pest tolerance, drought resistance, etc. Traits are transferred from one generation to the next by genes made of DNA (Mariani et al., 1990). About 12,000 years ago, our predator-larger families started to try their hand at culturing. First, wild types of crops such as peas, barley and lentils were grown, and wild animals such as goats and wild oxen were collected. ... At the end of the day, they moved outward, extending farming to areas of Europe and Asia. Biotechnology typically involves a wide variety of technologies and methods for the production of useful facilities, living organisms. The incorporation of biotechnology to agriculture allows effective use of scarce resources, decreases required the pesticides and insecticides and increases productivity ( Vasey, 1992 )
