Abstract

Background: Head lice infestation is one of the most important health problems throughout of the world. The species which cause pediculosis in humanus beings is Pediculus humanus capities. Objectives: The aim of the current study is to estimate the distribution of head lice among local and displaced secondary school girls to assess haemoglobin and packed cell volume in Kirkuk city. Methods: The hair of all students was examined by researchers and blood samples were drawn from each student for determination of haemoglobin concentration and PCV percentage. A questionnaire form was filled for each student including personal and family information. The student t-test was used to show significant difference of PCV and Hb between lice infested and non infested students. Results: The overall rate of head lice infestation among secondary students girls was 34.7% (displaced 42.7% and local 26.7%). The highest rate of infestation was among 16-18 years and lowest was among 13-15 years. The highest rate in displaced students was among middle educated status, while in local students among low educated status. The PCV and Hb values in infested girls were lower than non- infested ones

Abstract

In this study, the behaviour of reinforced sand under a square footing has been investigated. A series of bearing capacity tests were performed on a small-scale laboratory model, filled with a poorly-graded homogenous bed of sand, which was placed in a medium dense state using sand raining technique. The sand was reinforced with 40 mm wide household Aluminium foil strips. The aim was to study the load-settlement behaviour, bearing capacity ratio and settlement reduction factor, considering the effect of reinforcing strip length, with various linear density of reinforcement, number of reinforcement layers and depth of top layer of reinforcement below the footing. Generally the relation of load-settlement showed similar trend in all the tests. The failure was defined as the settlement equal to 10% of the footing width. The recommended optimum reinforcing strip length, linear density of reinforcement, number of reinforcement layers and depth of top layer of reinforcing strips, that give the maximum bearing capacity improvement and minimum settlement reduction factor were presented and discussed. Both bearing capacity and settlement reduction factor versus length of the reinforcing strips relation at failure have showed an improvement of the bearing capacity ratio by a factor of 3.82 and a reduction of the settlement reduction factor by a factor of 0.813. The optimum length of the reinforcement was found to be 7.5 times the footing width.

Abstract

Background: Thalassemia is one of the most globally common chronic hematological disorder. This inherited disorder is characterized by an abnormal production of hemoglobin protein resulting in a life-threatening disease of two main types α and β.In Kirkuk city it was found that, β-thalassemia was the most common disorder and various factors were found to be contributing to the counts of β-thalassemia including ethnic origins and migration that added more burden on the genetic pool of the region and on the inheritance of traits in that area. Objective: Evaluating the prevalence of thalassemia in Kirkuk city according to a number of parameters that included age, gender and ethnic background of patients along with the assessment of the effect of consanguinity marriage on the incidence of the disease. Patients &Methods: Total of (156) clinically diagnosed β-thalassemia patients attending “Thalassemia Unit “ in Azadi Teaching Hospital in Kirkuk City were questionaired and data were divided into four cohorts for evaluation; followed by statistical analysis. Results: No significant difference was detected in β-thalassemia distribution among males and females in Kirkuk city 2016; β-thalassemia was more prevalent in children born following the years of insecurity in the country generally and Kirkuk city especially. In addition, about (77.56%) of β-thalassemia patients were the outcomes of consanguinity marriage from the first degree cousin whom affected with β-thalassemia minor without their knowledge. Additionally, the distribution of β –thalassemia patients between different ethnic groups living in Kirkuk and the surrounding areas indicated a significant difference (p < 0.05) in the incidence of β –thalassemia in Turkman patients who had recorded the lowest incidence rate of (17.31%) compared to the Kurd patients where they recorded the incidence rate of (37.18%) and Arabs where they recorded the highest incidence rate of (45.52%) among total of (156) β –thalassemia patients where most of them came from rural areas or were internally displaced people. Conclusions: β- thalassemia disorder is one of the prevalent inherited diseases in Kirkuk city with increasing frequency among children in the ages of (1-3) years old. Besides, the distribution of β- thalassemia disorder did not vary among males and females in Kirkuk city in the year 2016 and it was concluded that, the frequency of β- thalassemia showed an increase in the years following wars and invasions in Kirkuk city. Moreover, consanguinity marriage increases the frequency of β- thalassemia incidence among both male and female patients. Additionally, individuals with minor β- thalassemia increase the ratio of β- thalassemia incidence among their children and the distribution of β- thalassemia differ according to different ethnic groups.

Abstract

The performance of flat plate solar collector is affected by the value of its slope angle with respect to horizontal plane, where the variation of slope angle changes the amount of incident solar radiation. So, using the solar tracking system for solar collector will get the maximum solar radiation, the application of the solar tracking system cost has high operation and maintenance. It is usually suitable to set the solar collector at a best fixed slope angle throughout the year with less reduction in solar radiation received on the collector surface. In this work, a best slope angles were calculated for solar collectors based on the monthly mean daily solar radiations on a horizontal surface over some Iraqi cities (Mosul, Rutba, and Basra). The total of rays flux incident upon a solar collector is mainly affected by the installation angle. The solar collector can be oriented at three different angle settings. The first angle setting is to adjust the collector monthly off to give highest incident solar radiation, while the second angle setting suggests the seasonally changes (Winter, Spring, Summer, Autumn) .The final adjustment for solar collector can be achieved using the mean value for the four seasons to get yearly averaged throughout the year

Abstract

The present study deals with the interaction between the magnetic field of Jupiter and ones of the Coronal Mass Ejections (CMEs) for three years (2011-2013) which includes the peak of Solar cycle 24. These interactions were studied through numerical simulation using Magneto hydrodynamic models (MHD) and solved numerically by Leapfrog method with the aid of MATLAB program. The data related to CMEs were derived from LASCO/SOHO, and were verified whether there are events or not by checking them from ERNE detectors (LASCO and ERNE are scientific systems on board SOHO). While the data which concern with Jupiter were taken from VOYAGER 1. The simulation were achieved in two stages; firstly, the beginning simulation of the lunched CMEs from the surface of the Sun until they reach behind the boundary of the magnetosphere of Jupiter through interplanetary using the ideal MHD model (conservative model), and secondly is being the simulation of the interaction between the magnetic field of the CMEs and ones of Jupiter. It is verified using Semi-relativistic MHD model. Accordingly, it was found that Leapfrog numerical analysis is the optimal and best method. In addition, the outgoing CMEs to Jupiter embraces impulsive type and associated with Flares. Furthermore, it has been noted from the numerical simulation that intensity of the final magnetic field after the interaction of CMEs magnetic field with Jupiter magnetic field is going to increase giving rise to positive correlation with the speed of the adopted CMEs. On the other hand, the fast MHD shock wave with convex surface was created, because the speed of the adopted CMEs were greater than Alfven speed.

Abstract

The purpose of this research was to study suitability of water in Lesser-Zab River for drinking, irrigation, fish production, swimming, and construction. Raw water samples from Lesser-Zab River were collected for eight months, from February 2013 to September 2013. The samples were analyzed for 15 water quality experiments. Sodium adsorption ratio, sodium percentage, and alkalinity percentage were also determined. The maximum values for temperature, pH, total acidity, total alkalinity, total hardness, chloride, turbidity, electrical conductivity, total salts, dissolved oxygen, five day biochemical oxygen demand, total solids, total suspended solids, total dissolved solids, and sulfate were 21.2 oC, 8.18, 20 mg/L, 188 mg/L, 180 mg/L, 11 mg/L, 127 FTU, 420 µmhos/cm, 268.8 mg/L, 9.2 mg/L, 6 mg/L, 1200 mg/L, 400 mg/L, 900 mg/L, and 0.0 mg/L, respectively. Lesser-Zab water can be categorized as a moderately polluted water with moderately hard to hard water. The water quality of the river remains within the standards for drinking water, but still requires appropriate treatment processes prior to consumption. Water in Lesser Zab River is considered excellent to good and entirely safe for irrigation. This water is also fit for fish and other aquatic animals and safe for construction, but not appropriate for swimming.

Abstract

Cloud computing is a paradigm for offer information technology services on the Internet, such as hardware, software, networking and also the storage can be accessed anywhere at any time on a pay-per-use basis. However, storing private data onto servers of the cloud is a challenging matter. Therefore, cryptography technique and authentication are used in this model to ensure confidentiality and proper access control of sensitive data. Therefore, in this paper I proposed a model to protect data in cloud computing. In this model the algorithm of the Rivest-Shamir- Adleman (RSA) is applied to the private data. Furthermore, the protocol of Challenge-Handshake -Authentication-Protocol (CHAP) is used to improve the security of the authentication as well. The results show this model is secure and practical.

Abstract

Because of the computers systems discovery and the use of computer networks between countries, security is very important to transfer confidential information over the networks; traditional cryptographic systems such as Rivest-Shamir-Adlemen (RSA) are depend on guesswork as well as mathematics. Information theory illustrates that conventional cryptographic systems cannot be regarded fully secure unless the private key ; which it is used once only ; is at least as long as the plain text. And another limitation is using ASCII value to represent the plaintext, So the repetition of characters in the plain text will appear in the cipher text therefore we have given approach to generate magic square of order 32 which cannot be easily traced and use this square in the cryptography which it is used to improve efficiency through providing an additional level of security to encryption. Through of the characteristics of magic squares, and it's some complex conditions (non-repetition property), these squares generates a huge numbers of non-duplicate random numbers which can be used to represent the numerals rather than ASCII values as well as the magic square is also used to generate the keys for public key encryption algorithms.

Abstract

This study deals with the emphasis on the economic value of Makhul Anticline rocks in Mid-Region of Iraq, and it includes a mining design system suitable and profitable to exploit these raw materials. Here, the recommendation is to use and apply the open pit bench mining to extract the rock beds because of thin overburden, and the waste materials which cannot be dumped inside the excavation site. The rock beds which are outcropped dipping on both sides of the anticline flanks have irregular topography. Development of the mine is usually quite simple. Enough overburden should be removed to expose sufficient rock beds for production and construction of new access roads. This kind of mine operation is worked on one side of flank sequentially downwards in series of steps or benches whose height is usually determined by the machines selected and which are recommended in this study with the height of bench in range of (4 – 5) m, the sidewall angle in range of almost (18 – 20)° from the vertical and the bench or haul road width in range of (8 – 10)m. Access to the bottom of the mine should be cut- across the benches down to the next step. The equipments recommended in this kind of exploitation are Front - End Loader, diesel powered, rubber – tiered shovel for loading broken rocks in Lorries, and Jack Hammer Poclaine machine for Digging and breaking rocks. The mining operation become more profitable and economic when the whole rock beds of different types are extracted all together for multifarious uses, and the use of the facilities available around the area, such as the paved main roads, railway crossing the area, main power line, Tigris river, cheap labors and different types of machinery are ready for use.
