The experiment aimed to Manufacture a device for checking the nozzles and testing its efficiency and to study the effect of research factors on the studied traits. The device was manufactured locally through using materials available in the Iraqi market. The system is Both Hydraulic and electronic (ISO 5682-1)1 relay on sensors technology and the test platform was built and designed on a movable trolly at the department of Agricultural Machines and Equipment / College of Agricultural Science / University of Baghdad. The design includes the use of mechanical water pump and electrical AC water pump. The design includes a nozzle holder that can accommodate three nozzles per test. The design also consists of spreading wings and stationary wing that can accommodate 50 vessels and 50 ultra-sonic sensors. All that is controlled by a main control unit which consists of three branch modules (each one of them is responsible to collect and analyze data from several sensors on each of the wings. The idea behind the design is to merge between actual spraying and the use of electronic sensors to analyze the size of the sprayed liquid in each of the vessels, the concept of the design is based upon Volumetric distribution of the liquid. The concept of the device was based on using ultra sonic sensors to measure the volumetric distribution of liquids. The experiment aimed to determine the effects of these factors on flow rate, spraying angle, sprayed area, spraying swath, volumetric distribution (CV), and symmetry. The experiment was conducted at the college of Agricultural science, Baghdad University. The results showed that the spraying pressure had a non-significant effect on flow rate. However, increasing the pressure from 3.0 to 5.0 and then to 7.0 bar resulted in flow rates of 1.314, 1.286, and 1.36 l/m, respectively. The status of the nozzle (new or worn) did not significantly affect the flow rate, with new nozzles registering a slightly higher flow rate of 1.327 l/m compared to worn nozzles (1.312 l/m). On the other hand, the type of nozzle had a significant impact on flow rate, with plastic, brass, and steel nozzles registering flow rates of 1.243, 1.422, and 1.29 l/m, respectively. Regarding the spraying angle, the results indicated that the spraying pressure had a significant effect. Increasing the pressure from 3.0 to 5.0 and then to 7.0 bar resulted in spraying angles of 132, 132, and 136 degrees, respectively. The nozzle status significantly affected the spraying angle, with worn nozzles resulting in a higher angle of 137 degrees compared to new nozzles (130 degrees). However, the type of nozzle did not significantly affect the spraying angle. For the sprayed area, the spraying pressure had a significant effect, with higher pressures resulting in larger sprayed areas. Worn nozzles also significantly increased the sprayed area compared to new nozzles. The type of nozzle had a significant impact on the sprayed area, with plastic, brass, and steel nozzles resulting in areas of 70.4, 80.44, and 89.16 cm2, respectively. The experiment proved that nozzles must be tested periodically, otherwise they start to perform beyond the parameters they were designed to perform with.
This research is considered a simple attempt and effort which is it first and last target is to point at the procedures of the taxes account that aims to reduce the taxes from the persons and give free to the person who estimates the tax to practice what comes from the competent authorities to describe the person who estimates the tax and not an accountant who practice the accountant procedures which are imposed on him by the annual terms from higher administrations , So he can not evaluate state of the person who pay the tax , and he might be dissatisfied with his job , because his role can’t be activated from the general foundation taxes.
And so , this research includes four fields:-

As a result of this survey three species of Hymenoptera representing two separate families, which have been reared from ootheca of cockroaches were recovered. These were: Evania dimidiata Fabricius, Evania appendigaster (Linnaeus) (Evaniidae) and Anastatus longicornis sp. n. (Eupelmidae) which described here as a new species from Iraq.
Amebiasis, related to the pathogenic parasite Entamoeba histolytica, is a prominent cause of diarrhea globally. Amebiasis is primarily a disease of impoverished communities in developing nations, although it has recently arisen as a significant infection among returning tourists and immigrants. Severe cases are linked to a high case fatality rate. Although polymerase chain reaction (PCR)-based diagnosis is becoming more widely available, it is still underutilized. Treatment with nitroimidazoles is now suggested, however novel parasite medication research is a top priority. To avoid problems, amebiasis should be considered before corticosteroid therapy. Because there is no effective vaccination, sanitation and availability to clean w

Show MorePoisoning with toxic substances accidently or deliberately can be life threatening and especially in some countries that lack the essential tests and facilities to identify the types and causes of these toxic substances. In Iraq, as many other countries, poisoning is one of the chronic public health problems. However, very little literature about the pattern of poisoning cases, types and age is available in Duhok Governorate. Therefore, this study was conducted to determine the most common patterns of poisoning and the related age and gender in Duhok Governorate from 2016-2018, which would possibly contribute to the early diagnosis and treatment of poisoning. The present study was conducted for three years, started from 1st of

Show MoreA study was carried out to analysis of some heavy metals in nine different types of vinegar, belong to Grape, Apple, Synthetic White, Date, Hawthorn, Garlic, Cactus, Pomegranate and Ginger vinegar, which are locally available in Iraqi folk medicine markets. The concentrations of heavy metals in the studied samples including, Cr, Mg, Mn, Zn, Fe, Cd, Ni, Pb and Ag, were determining by using flame atomic absorption spectrophotometry. All data were subjected to statistical analysis by calculating accuracy, precision and correlation coefficient for each concentrations level. The results indicate that Ni was recorded the highest concentration in all studied samples except, Ginger and cactus vinegar, each one receded the highest concentration valu

The aim of this study was extraction of jojoba oil using different solvents. A mixture of waterhexane and water-ethanol are used as solvents to extract jojoba oil in a batch extraction process and compared with a pure solvent extraction process. The effects of particle size of crushed seeds, solvent-to-water ratio and time on jojoba oil extraction were investigated. The best recovery of oil was obtained at the boiling temperature of the solvent and four hour of extraction time. When seed particle size was 0.45 mm and a pure ethanol was used (45% yield of oil extraction), whereas, it was 40% yield of oil at 25% water-hexane mixture. It was revealed that the water-ethanol and water-hexane mixtures have an effect on the oil extraction yield. T
