In this paper, the composite laminates were fabricated to different weight percentage of uni-directional and stitched cross mat E-glass fibers, glass and Kevlar fiber reinforced with epoxy resins and hardener. For laminates fabrication epoxy matrix is maintained is constant weight percentage (60%) and glass fibers with different stacking sequences is added with various weight percentage. Mechanical behaviour of composites such as tensile property, flexural property & impact resistance are study in this investigation. The various geometry of E-Glass/Kevlar fiber reinforced laminates manufactured by hand lay-up method and followed by compression moulding technique. Where epoxy is constant (60%) and change the fiber percentage, specimens prepared with difference stacking sequences material are tested. The results show tensile strength and impact resistance are high to the stitched cross glass(SCM) fiber mat(40% ) .The flexural strength and natural frequency is high in order to Chopped strand (CSM) mat(10%)/Kevlar(K) fiber(30%), CSM(30%)/K(10%).

The trend of urbanization in Iraq is exerting stress on civic authorities to provide basic requirement such as safe drinking water, sanitation and infrastructure. The rapid growth of population has exerted the portable water demand, which requires exploration of raw water sources, developing treatment and distribution systems. There is a need to study the water treatment plants for their operational status and to explore the best feasible mechanism to ensure proper drinking water production with least possible rejects and its management. A case study has been conducted to evaluate the process of treatment and to find out the problems of drinking water treatment process in Al-Rumaitha drinking water treatment plant(RWTP) lies in the city of Rumaitha in Muthanna province,Iraq. In general, conventional treatment is provided having a sequence of alum addition, coagulation, sedimentation, filtration and disinfection by chlorination. Water treatment plants are playing an important role in purifying and supplying the pure water to the people. This plant consists of two projects, The design capacity of the old project (88000 m3 / day ) and for the new project ( 820 m3 / hr) while not know the actual capacity of the plant due to lack of flow gauges. In this study, the removal efficient of turbidity will be addressed as well as three factors are, total dissolved solids , pH and values of chlorine added at February,2015 of old and new project for raw and treated water, then compared within Iraqi limits to note the problems of the plant and how to avoid them in the easiest and cheapest methods. It was found that the average value of the removal efficiency of the turbidity were about 51.5% of old project and 53.8% of new project which is relatively low due to the absence of the permanent maintenance and the continuous clean out for the sedimentation basin. The average value of T.D.S concentration of treated water were 910.8 ppm of old project and 911.5 ppm of new project . The free chloride (CL2)of old project was 2.1 ppm and of new project was 2.6 ppm. While we don't note that the strong influence of the change in temperature on the factors which studied in this project. The pH value is almost constant values for the water of the Euphrates River. In addition to the study of these factors there are notes on the treatment plant should study and develop plans for processing and control. It is upon these observations lack of flocculation basin, limiting the efficiency of the sedimentation basins despite large size disrupt dissolve alum basins as alum is added to it manually, leading to differing concentrations of alum solution. From time to time and other problems presented piping at the station, as is since the establishment.

The massive amounts of data collected today by software in fields varying from academia to business and many other fields, is increasingly becoming a huge problem due to storage technologies not advancing fast enough to provide the performance scalability needed. This is even truer for data which are highly organized and require analysis while being stored in databases and being accessed by various applications simultaneously. As database vendors struggle to gain more market share new technologies emerge attempting to overcome the disadvantages of previous designs while providing more features. Two popular database types, the Relational Database Management Systems and NoSQL databases are examined. The aim of this paper was to examine and compare two databases from these two database models and answer the question of whether one performs and scales better than the other.

The Study of heavy metal was carried out at mechanic village along Abeokuta-Ibadan Expressway for the presence of heavy metal and uptake efficiency of plant species as a means of phytoremediation. The concentrations of heavy metals determined from the soil of the mechanic village and compared to a control farmland located as Federal University of Agriculture. The soil sample collected at the base of different species of tree showed that the heavy metals were below permissible levels (FAO/WHO standard) and show no significant difference in the range of mean. Absorption of heavy metals by the bark of the trees in the mechanic village was evident when compared relatively to the presence and uptake of the heavy metals from the soil by tree in the average farmland. The mean concentrations of the heavy metals in the soil of the farmland are in this order of magnitude Cd>Cu>Pb, while the mean concentration of the heavy metals in the soil of the mechanic village are in the order of magnitude Pb>Cu>Cd. Lead has the least concentration in the farmland, while in the mechanic village, it is the predominant heavy metal detected which also shows greater significant different at p<0.05 with a value of 24.34 mg/kg which indicates area of high mechanic activity. While the concentration values of heavy metals in the barks in comparison to the FAO/WHO and EC/CODEX standard for these heavy metals shows that the concentration of the heavy metals in those vicinities is within the normal range for cadmium and copper, but the lead present is above the WHO/FAO standard at 0.299 mg/kg and close to the EC/CODEX standard. It can also be concluded that the uptake efficiency of heavy metal under study of the three species are in the order magnitude Mango>Cashew>Neem. We can also recommend that for better efficient cleanup especially where an area is polluted with copper, mango is best bet for the uptake of such metal while if an equal proportion all many heavy metals are evident then it will be better to use Neem as a phytoremediating plant.

Erythema multiforme (EM) is an acute mucocutaneous disease which has been associated with herpes simplex virus (HSV) infection and drugs. This report presents a case of EM minor with a prompt diagnosis and appropriate treatment. A 19-year-old male, a military recruit, reported with a chief complaint of multiple, diffuse, painful oral ulcerations for more than 3 days. An intraoral examination showed multiple large ulcers on the bilateral lateral borders and ventral surface of the tongue, bilateral buccal mucosae, and gingivae. “Target” lesion was found on the skin surface of his body or extremities. The patient was treated with corticosteroids. A follow-up oral examination revealed that all oral ulcers had completely cleared up after the 7-day corticosteroid treatment. One year after treatment, the patient remained disease-free. We concluded that EM is a mucocutaneous disease that requires a prompt and precise diagnosis. Once the disease is confirmed by the clinical presentation, it usually dramatically responds to treatment with a medium or high dose of corticosteroids. Key words: erythema multiforme, target lesion, corticosteroids.

This paper proposes an image hiding technique that exhibits good quality with higher embedding capacity. In this technique, both secret and cover images are divided into non overlapping blocks. The secret image is embedded into a cover image block by block using Range Normalization Technique. This technique exhibits advantages of high embedding capacity with less computational complexity. Compared with the existing algorithms, the quality of the stego and reconstructed image is found to be good.

A study of delineation of Iron (Fe) and Manganese (Mn) status in soils of Central Research station, Akola was conducted during the year 2006 and 2007. Detailed maps of micronutrient also prepared. Delineation of study area was completed with help of global positioning system and for predicting available cationic micronutrient status extraction with chelating agent such as di ethylene triamine penta acetic acid (DTPA) is used. The soils of Central Research Station were found 20 per cent deficient in iron and 7 per cent deficient in manganese. While the available micronutrient status of Central Research Station soils was found as iron 0.12 to 16.32 and manganese 0.32 to 16.78.

This study has examined the effects of architectural anatomy of opera hall on improving the quality of place identity. By measuring the effects of place identity on the inner aspects of human which are influenced by the physical and social environments it has investigated the results of a balance between internal and external environment. To assess the anatomical effects of urban landscape, two components of subjective landscape including perception and diversity and the component of objective landscape including form and order have been measured. The current survey is descriptive and the statistical population has been Shiraz which is a city in Iran. To analyze the data the SPSS software has been used. The results have been investigated in two levels of descriptive and inferential statistics. In the inferential statistics, Pearson correlation coefficient has been used to evaluate the research hypotheses. The results of this study indicate that between the dimensions of landscape, the component of subjective landscape has the highest empact on the place identity and in the second place, objective landscape has the empact on the place identity. Anatomical effects have an important role on improving the quality of place identity of Shiraz citizens and in order to enhance the place identity in the urban landscape it is also required that they will be inspired and operated.

Jihadism is a type of Islamists movements that in addition to belief in following the principles of Islam, has especial emphasis on Jihad (sacred war) as one of the basis of Islam. The origin of this movement in general, is Egypt, andin particular, Muslim Brotherhood organization (Ikhvan ul-Muslemin). In second half of twentieth century due to factors like torture and prison, identity crisis, 1967 defeat from Israel and intense class differences and closed political space, groups with extremist attitudes and equipped with ideas of extremist theorists like Sayyed Qotb, have been separated from the Muslim Brotherhood and by accepting members from youth, students and others, they have created organizations that their main purpose is armed struggle with government and overthrowing it in order to establish an Islamic government. These organizations that their most popular ones are Al-Takfir Va Al-Hejreh, Army Technical Academy and Al-Jihad, soon began armed struggles with Egypt government.
