Abstract
This research includes study the electrical properties using programming simulation SCAPS-1D, depending upon on numerical analysis from simulation of solar cells, where solar cell consisting of Cadmium Telluride (CdTe) used as absorber layer with thickness (0.05-5.0µm) and the window layer CdS:O with thickness (0.025µm) and Buffer Layer (Zn2SnO4) with thickness (0.05µm), (FTO) layer as transparent conductive oxide layer (TCO) with thickness (0.1µm), and added background reflection layer (BSF) which placed between metal back contact layer and the absorption layer in order to increase the amount of Voc and the efficiency of the solar cell because the background reflection layer (BSF) works to reduce recombination in the back contact, and the carriers are strengthened by reversing it towards the main link. With a thickness of (1.0µm), the results obtained were {Voc=0.83V, Jsc=36.90mA/cm2, FF=85.55%, η= 26.33%}. The thickness of the absorption layer has been studied and the effect of temperatures and bandgap energies was studied.

A rapid, sensitive and indirect spectral method was developed to estimate the mesalazine in the aqueous solution, as the method relied on the oxidation and reduction reaction of the mesalazine oxidation with an increase (calculated) from the oxidizing agent of bromate - bromide mixture in the medium of hydrochloric acid. The remaining (non-reducing) concentration then reacts. With a constant amount of methyl orange dye leads to color bleaching. The residual dye was followed at 507 nm wavelength. The relationship was linear between residual pigment absorption and increased drug concentration, and the micrographic quantities of mesalazine that followed Beer ٬ s law limits were estimated from 0.5 to 12.5 µg /ml with molar absorptivity 2.03 x 104 l.Mol-1.. cm-1 and Sand ell’s sensitivity index (0.0075357) µg / cm2 . A relative standard deviation whose value does not exceed 0.690% and the C recovery value not less than 99.05%. The method was successfully applied to the pharmaceutical preparations as tablets and it was compatible with the original content of the pharmaceuticals and with the results of the standard addition method.

This study included calculating the stability constants and stoichiometries of some binary complexes formed from the interaction of seven of metal ions (Cr+3,Mn+2,Co+2,Ni+2,Cu+2,Zn+2 and Cd+2) with Ciprofloxacin-HCl. This study was carried out using Potentiometric Titration Technique at different concentrations of the drug and the metal ion and at temperatures (288,298,310,318 and 328 K±0.1) in aqueous solution. Although, there are many methods available to study the stability of metal-ligand complexes, pH-metric is most frequently used to determine the stability constants. Hence, (Calvin - Bjerrum pH-metric titration technique) as adopted by Irving–Rossotti was used to calculate of stability constants. The results of the concentration effect study showed that the formation of complexes were more stable in dilute solutions, and through study of the temperature effect it was concluded that the stability of the complexes can be increased with raising temperature, and the stability constants value obtained were used in the calculation of thermodynamic parameters 〖(S〗^o,H,〖G〗^o). The results of this study also showed that the ciprofloxacin tends to form two types of metal complexes in the solution (ML1),(ML2) and this indicates that the reaction ratio between the drug and the metal ion was (1:1) and (1:2)(M:L) respectively for all metal ions. These ratios depended on the nature of the ligand or the metal ion, and the stability of the complexes formed increases according to the following arrangement (Mn+ 2< Co+ 2< Ni+ 2< Cu+ 2> Zn+ 2) and this arrangement is compatible with Irving Williams’s arrangement for the stability of the elements.

Abstract
‎ The recent paper studies the impact of coccidiosis on blood levels of cattle ‎since it is one of the parasites that attack both‏ ‏poultry and cattle epidemically and ‎infect the intestine leading to big economical loss as well as high deaths of those ‎animals. Due to the few number of relevant studies that present for the this parasite ‎effect on blood level as well as the levels of anti-oxidation, Glutathione, I did such ‎the study which includes 40 cows and 35 calves of 2-3 months of age from which a ‎stool sample was taken plus a 5 mml blood sample. Next, I diagnosed the infected ‎animal through testing the symptoms of those animals and examining the stool by ‎both floating and smear methods directly to find the ovarian cysts of coccidiosis. ‎Then, I determined the level of infection (the number of parasites per 1 gm of stool) ‎by using Macmaster way so the animals were divided into two groups (infected and ‎non-infected). After that, some biochemical tests were done to check the levels of ‎Malondialdehyde (MDA) as a final outcome of lipid peroxidation using colorful ‎TBA ase and to measure the absorption of ( 450 um) ‎‏ ‏wavelength. Also, I divided ‎the Glutathione (GSH) level in blood plasma using Elmanz method.‎

The research aims to reveal the reality of the comprehensive quality standards for physics laboratories in preparatory and secondary schools in Mosul. The research sample consisted of (33) secondary and intermediate schools in Mosul city for the academic year 2019-2020. To achieve the objective of the research, the researchers prepared a questionnaire from five fields, and in its final form it consisted of (55) items. The reliability of the scale has been validated by appropriate methods. After distributing the research questionnaire, the results showed the following:
Non-compliance of laboratories in Mosul with the principles of total quality in the five journals, and lack of commitment to use the laboratory in education in general.
The researchers concluded that observing the overall quality in the laboratories of the city of Mosul is not considered in addition to the lack of work inside the laboratory, but in schools where there is a laboratory such as distinguished students ’schools, the work is limited to the teacher and the laboratory assistant without involving students in the work on experiments in the laboratory, but their role It is only receive and watch. The researchers recommended several recommendations, including the necessity to observe the overall quality in the laboratory and activate the laboratories inside the Nineveh Governorate in general and the city of Mosul in particular to increase the preparation of follow-up committees to review the development of laboratory work in the Nineveh Governorate to adopt the comprehensive quality standards in the processing and use of laboratories.

This study was performed to separate and identify a number of amino acids present in the bark, sapwood, and heartwood of Ceratonia siliqua L growing in Mosul, seven of the amino acids were identified in the bark, eight in the sapwood, and seven in the heartwood. In general, the number of identified acids in the carob understudy is eight, which are: Aspartic Acid, Phenylalanine Acid, Glumatic Acid, Lysine Acid, Glycine Acid, Tryptophan Acid, Lucien Acid, and Serine Acid. The highest quantities were in the sapwood and the lowest was in the bark. These results are consistent with the results of the study samples (bark, sapwood, and heartwood) of carob trees. The bark, sapwood, and heartwood are similar in terms of amino acids with the exception of serine, which did not appear in both bark and heartwood, and glutamic acid did not appear in sapwood, the presence of this large number of amino acids in carob wood may be due to the ability of carob trees to fix nitrogen in root nodes.

Vitamin D affects infertility among women. Via vitamin D, were tested in 60 women with infertility and 40 control group. The results showed a low significant elevation in the concentration of Vit. D in infertile women, compared to the healthy women at a significant level of (P = 0.001). The results also showed a significant decrease in the level of the vitamin in infertile women compared with healthy women (control group) at a probability level (P = 0.01) for all age groups, the age is a major factor affecting vitamin D levels, and the elderly are usually more vulnerable to vitamin D deficiency due to the decrease in the skin's production of vitamin D with age and fertility decreases, especially at the age more than of 35 due to the decrease in the egg quantity and quality, as an egg is sent from the ovaries to the female's uterus every month from the time of puberty to menopause. The level of vitamin in infertile women with a regular menstrual cycle is higher compared to infertile women with an irregular menstrual cycle, as this indicates the possibility of vitamin D deficiency, one of the factors that affect the regularity of the cycle of menstruation. This vitamin had a strong positive relationship with Irregular menstruation for different age groups. Finally, the result revealed vitamin D as a new indicator of increasing infertility and miscarriage risk for women.

Abstract In this paper, a doped 3C-SiC with two dopant materials, Al and Cr to obtain p and n type semiconductors respectively, was used to as a basic component in the solar cell structure used in the current study. The present study examined the impact of the main environmental conditions (temperature and light) on the PIN 3C-SiC solar cell. Simulation was accomplished for different levels of illumination from (250 to 1200) W.m-2 and temperature from (300 to 400) k. SCAPS simulation software is used to evaluate the influence of temperature and light intensity, which directly affect the electrical properties of the cell. The results revealed that illumination has a great impact on the current of the circuit, where the current of the short circuit JSC increases linearly with increasing the level of intensity. On the other hand, it was proved that the temperature has a sever influence on the voltage of the cell. The voltage of the open circuit VOC considerably decreases due to the decrement in current of saturation that reduces directly with an increase in temperature.

A field experiment was conducted in the fields of the Faculty of Agriculture, Tikrit University for the 2019-2020 agricultural season to study the effect of plant spacings and the level of nitrogen and boron fertilization on growth and yield of broccoli in a gypsiferous soil. The study included three factors, the first factor, plant spacings included four distances (35, 45, 55, and 65 cm) (D1, D2, D3, and D4), respectively. The second factor, the level of nitrogen application, included two levels of nitrogen, which are 70 and 140 (kg N ha-1) (N1 and N2), respectively in the form of urea fertilizer (46% N). The third factor was the level of boron application and it included two levels of boron, which are (without boron addition and 6 kg B. ha-1) (B0 and B1), respectively, in the form of boric acid (17% B). Results showed that nitrogen level N2 gave a clear significant increase compared to the N1 level, as the nitrogen concentration in the vegetative part and the blossom disc in the second level N2 reached (2.79 and 3.02%), respectively, while in the first level N1 it reached (2.53 and 2.53%). The concentration of sulfur in the shoot and the floral heads for the second nitrogen level reached (0.501 and 0.389%), respectively, with a significant increase compared to the first level N1, which gave an average of (0.464 and 0.368%), respectively, and the concentration of boron in the shoot and the floral heads for the second nitrogen level N2 (19.15 and 36.95 mg B; kg-1), respectively and was superior with significant increase compared with  the first level N1, which gave an average of (17.58 and 33.61 mg B kg-1), respectively. Application  of boron fertilizer at a rate of (6 kg B. ha-1) resulted in a significant increase in the content of leaves and floral heads of boron, reaching 22.40 and 38.41 mg kg-1), while the control treatment gave a rate of (14.32 and 32.14 mg kg-1). ) Respectively. Following the distance 65 cm between broccoli plants (D4) led to a significant increase in the concentration of nitrogen, boron, and sulfur in the leaves and the floral heads. The triple interaction between nitrogen (N) and plant spacings (D) and boron (B)  (treatment D4N2B1) gave the highest value for nitrogen, boron, and sulfur concentrations in leaves and the floral heads.

Abstract: Nineveh province  was chosen as an applied model for the study, because it is one of the most imputant governorates in potato cultivation and production. The preliminary data of the study were collected according to a simple random sample of potato growers for the spring harvest (2019). The total number of farmers in the sample was 315 representing 23% of the study community chosen by using a questionnaire for this purpose, and among the most important goals which the study seeks to achieve was to determine the optimal production levels (minimizing costs and maximizing profits) in the short term being among the key targets of the successful farm manager, in addition to estimating the function of costs for the short term for the total spring harvest (in 2019). The research comprises the flloawing items:
First: Estimating the production function (Cup-Douglas) using OLS method to represent the relationship between the dependent variable that represents the quantity produced of potato yield (y) of dunum and the independent production factors used;  labor (L) worker / day and capital (K) million dinars.  it is significamt  that the double logarithmic function is the most consistent function with economic logic and in representing the relationship in terms of passing statistical and standard tests. The labor resource included (family labor and wage labor), while the capital resource included all items of capital expenditures (seed quantity, fertilizers, pesticides, mechanical work, irrigation wages, fuel, and maintenance wages), then finding economic derivatives (marginal and average output) , equal output curves, short-term cost function was derived from Production function.
Second: The total short-term cost function of the sample farms was estimated, and the output from the potato crop was counted as an independent variable, while the calculated total costs (million dinars) counted as a dependent variable. The quadratic function was the best function based on statistical and standard tests, economic derivatives (marginal and intermediate costs) were found, and the level of output that maximizes profit from potato crop production was determined, and cost elasticity was derived. Finally, the most important results were mentioned and recommendations were proposed by the study on the subject, including: - that suggests presence of a large number of obstacles to the production of the crop, the most prominent of which was the high prices of seeds, fertilizers and pesticides, the lack of machinery and equipment for harvesting the crop which leads to high costs of harvesting, and not considering the export of the manufactured production  which in turn affects decisions about this crop. The researcher recommends that the Ministry of Agriculture expands the area of land belonging to it which is suitable for planting potatoes, and operating large numbers of agricultural engineers and large numbers of manpower according to partnership,  investment or Self-financing  schemes, and this would accommodate large numbers of labor that consequently contribute to reducing unemployment, creating job opportunities and the establishment of the development of potato cultivation project through their dependence on modern methods.

This study included calculating the stability constants and stoichiometries of some binary complexes formed from the interaction of seven of metal ions (Cr+3,Mn+2,Co+2,Ni+2,Cu+2,Zn+2 and Cd+2) with Ciprofloxacin-HCl. This study was carried out using Potentiometric Titration Technique at different concentrations of the drug and the metal ion and at temperatures (288,298,310,318 and 328 K±0.1) in aqueous solution. Although, there are many methods available to study the stability of metal-ligand complexes, pH-metric is most frequently used to determine the stability constants. Hence, (Calvin - Bjerrum pH-metric titration technique) as adopted by Irving–Rossotti was used to calculate of stability constants. The results of the concentration effect study showed that the formation of complexes were more stable in dilute solutions, and through study of the temperature effect it was concluded that the stability of the complexes can be increased with raising temperature, and the stability constants value obtained were used in the calculation of thermodynamic parameters . The results of this study also showed that the ciprofloxacin tends to form two types of metal complexes in the solution (ML1),(ML2) and this indicates that the reaction ratio between the drug and the metal ion was (1:1) and (1:2)(M:L) respectively for all metal ions. These ratios  depended on the nature of the ligand or the metal ion, and the stability of the complexes formed increases according to the following arrangement (Mn+ 2< Co+ 2< Ni+ 2< Cu+ 2> Zn+ 2) and this arrangement is compatible with Irving Williams’s arrangement for the stability of the elements.

A new series of organotellurium compounds derived from 4,-4-dihydroxy azobenzen have been prepared by the reaction of 3-HgC1-4-OH-C6H3N=NC6H4-OH (A) with TeBr4 and P-CH3OC6H4TeBr3 to give (3-(P-CH3OC6H4TeBr2)-4-OHC6H3-N=N-C6H4-OH) (B̅) and (3-TeBr3-4-OHC6H3N=NCH4-OH) (B) respectively, reduction of B by sodium sulphide gave the corresponding organotellurenyl compound (C), (3-TeBr-4-OH-CH3N=N-C6H4-OH). Compound (D) (OH-C6H4-N=N-CH3-4-OH-3Te)2 has been prepared by reduction of compound B or C by hydrazine hydrate. Reduction of B̅ gave the corresponding telluride 3-(P-CH3OCH4Te)-4-OH-CH3N=N-C6H4-4-OH (E). All compounds have been characterized, by IR and 1H NMR spectral data and meting point was determined. The molar conductivities of the halogenated compounds (B, B̅,C) in DMSO and DMF show some weak electrolytic behavior.
