The phenomenon of money laundering is one of the biggest challenges facing financial and banking institutions in countries around the world. This phenomenon is one of the most serious challenges facing the Iraqi economy at the moment. Thus, the central bank of Iraq has taken serious measures to limit it. These measures represent economic policy to combat the money laundering by putting control on private banks and money transfer checks to enter the currency auction. This research aims to measure and analyze the phenomenon of money laundering. In order to accomplish this, aim a descriptive statistic is used, and the standard model used was )FMOLS(. depending on data obtained from the central bank of Iraq from period 2003 to 2021. The research found that the measures taken by the central bank did not lead to a decrease in the amount of money laundering. Where any increase of these measures which represented in )Money supply, sales of the Central bank of Iraq of foreign currency and exchange rate( by )1%( lead to increase the money laundering by )%1.29 و ،%0.39 ،%0.27( respectively. In conclusion, the research main recommendation is to implement the instructions of the office of combating money laundering accurately as well as to strengthen international cooperation in this field.

The maize crop is one of the main grain crops in Egypt after wheat. It is used in human consumption and many industries. The study aims to study the development of production capacity and the most important cost items for the maize crop in Ismailia Governorate during the period )2000-2021(, and to estimate the total costs function to identify On the quantity of production that maximizes the profit and the quantities that minimize costs in order to determine the position of the Governorate in the production of the crop, as well as the indicative relationships of the net yield and the factors affecting it. Using some statistical analysis methods for estimated them . the study showed that there was a significant increase in productivity and total production . while there are no significant in cultivated Aria of the maize crop in Ismailia Governorate during the period )2000-2021(. By studying the economic indicators of the crop, it was found that there is a general time trend increasing annually and statistically significant at 1% a level of significance for each of the annual average of the farm price, the average value of the total revenue, the annual average value of the net return, while the time trend for the development of the value of the net return on the invested pound was decreasing annually Statistically significant at the significance level of 5%. and the optimum volume of production that reduces costs for the crop was estimated by about 27.64 ardebs / feddan at the lowest cost estimated at about 6,825.63 pounds per ardeb, and the economic production that maximizes profits At about 35.32 ardebs/feddan, at a total cost estimated at about 985.61 pounds per feddan, the average total revenue per feddan was 4158.44 pounds at actual production and about 8701.44

A total of 40 Saidi ewes were used approximately 2 years of age and had an average initial body weight (BW) of 40 ± 2.46 kg. Ambient temperature (AT) and relative humidity (RH%) were recorded simultaneously while measuring the physiological responses at the level of the surface of the animal. All physiological measurements were recorded at early morning at 6:00 AM and afternoon 12 PM. The lowest rectal temperature (RT°C) was recorded in semi open models at AM but results recorded that there was no significant differences in RT among the different housing models at PM. The highest temperature humidity index (THI units) was recorded in open and semi open housing models. The highest skin temperature (ST) was recorded in single roof housing model at AM. The lowest plasma total protein (TP) was recorded in open housing model and the same trend was recorded in globulin (GL). Results also showed that there were insignificant differences in albumin (AL) among different housing models.

: A total of 80 Saidi ewes were used approximately 2 years of age and had an average initial body weight (BW) of 40 ± 2.46 kg. Ewes were divided in two experiments 40 mature saidi ewes in each experiment, The first experiment was in mating season September, 2018 and the second experiment was in mate season January, 2019. Ewes in two experiments were randomly assigned to 4 groups raised under four housing model which was Double Roof Close, single roof close, semi open and open housing model. Ewes, mated in September, lambed during January. Ewes, mated in January, lambed during May. Ewes were kept in double roof and open model houses had higher Conception rate than the other houses in winter and summer seasons respectively. Ewes in semi open and open model in season's summer and winter had higher number of service per conception. The analysis of variance showed that housing models had no significant effect on average birth weight and total birth weight/ewe of lambs. However, lambs born in double roof and single roof housing model tended to have a higher average birth weight than born in semi open and open models.

: The purpose of the study is to determine the effect of the Egyptian policies on production of tomato and potato by utilizing the Policy Analysis Matrix (PAM). The study was based on descriptive and quantitative statistics in analyzing the data collected. Results show domestic price of tomato is equal to international price, which means that tomato producers neither received government support nor incurred implicit taxes, domestic resource cost ratio amounted to 0.30, indicating that Egypt enjoyed a comparative advantage in tomato production. It is evident that value added in potato domestic prices is lower than that in international prices, which means absence of protection policy as an average from 2015 to 2019. Such result means that the government has been imposing taxes, either direct or indirect, or it has been subsidizing potato imports, domestic resource cost ratio amounted to 0.85, indicating that Egypt enjoyed a comparative advantage in Potato production during the study period, which means that domestic production of potato is preferred than dependency on imports.

: The experiment was conducted to estimate the levels of benzoquinones in biscuits that were baked at 180 ± 5°C for 20 minutes with five different types of flour: wheat flour, barley, white maize, sorghum and oats, infested with the confused flour beetles, Triboliumconfusum (Du Val) and stored for three months. The results showed the presence of high levels of benzoquinones in all types of biscuits. Barley biscuits recorded the highest percentage at 11.10 mg/g, followed by wheat 6.27 mg/g, white maize 5.10 mg/g, sorghum 2.72mg/g and oats 0.95 mg/g, respectively. Also the data showed a positive correlation between the total number of insects in the infested flour before baking and the level of benzoquinones after baking. The cracking of benzoquinone by the heat of the oven during the baking of biscuits resulted in many harmful organic compounds, which were identified by analysing it on GC/MS. All of the major compounds were present in large percentages in all of the biscuit samples, namely: 1,4,4-trimethylcyclohexa-2-en-1-ol, which represented the highest percentage of the separated compounds, with a peak area percentage ranging from 41.95-50.92%; 2-Octenal, 2-butyl, which represented a percentage of 21.85-23.64%; 7-Octen-4-one, 2,6-dimethyl, which represented a percentage of 12.55-17.54%; valeric acid, 4-tridecyl ester, represented by 6.25– 9.14%; phenol area percentage was 3.53–7.48% and area percentage of Carbamic acid phenyl ester was 0.55–3.03%. In addition to 6 other minor compounds. We concluded that made from infested flour are extremely dangerous due to the presence of benzoquinone and many other organic compounds produced by heat cracking. It also showed the sensory evaluation of the biscuits made from infected flour revealed an undesirable taste, odor and darkening in color. Commercial fraud exposes us to the same risk by combining infested flour or bran with non-infested flour.

Meanwhile, foliar application of potassium silicate “P.S.” and/or α-tocopherol “α-Toc.” alone or in combination significantly improved the morphological and physiological characteristics compared with control. The foliar application of tocopherol alone was more noticeable compared to sprayed with potassium silicate alone particularly at the higher rates as it maintained the growth and plant performance under abiotic stresses.
