Abstract The effect of mid layer on flexural strength and young modulus were studied using Instron testing machine. E-glass/epoxy composites were manufactured using hand lay-up technique. The laminated composites were prepared with dimension (4x10x80) mm, Epoxy composites were reinforced with multidirectional layer of woven glass fiber and random glass fiber of stacking sequence [M]16, [R]16, [M/R//M1/M1//R/M]s, [//M/R//]s, and [R/M//R1/R1//M/R]s. The effect of transverse loading on flexural strength and young modulus was investigated for specimens subjected to Three-point bending test. The results show that the mid layer (M1/M1) which had (homogeneous distribution) has higher flexural strength value and young modulus than mid layer (M1/R1) and (R1/R1).

Abstract The role of Zinc in alleviating B-toxicity in terms of adventitious root formation (ARF) in cuttings of mung bean was studied. The toxic level of B in addition, to the promotory conc. of Znsalt was determined. Two of Zn-salts were tested (sulphate, and chloride), auxin was supplied as inductive treatment to enhance rooting response. 1. The toxic level of boron was 150 (µg/ml), this reduced growth parameters in terms of rooting response to 50% compared to control. 2. Zinc sulfate at conc. 1 (ppm) and Zinc chloride at 5 (ppm) developed the highest rooting response in mung bean cuttings. 3. For Boron detoxification, Zn-(sulphate and chloride) were supplied as pre-treatment, posttreatment or simultaneously with toxic-B. The best treatment for boron detoxification occurred completely by supplying Zinc sulphate and chloride prior to toxic-B treatment (pre-treatment), but after supplying auxin inductive treatment. 4. The protective role of Zinc-sulphate and chloride significantly enhanced the average of root number/cutting to its highest level in control treatment.

ABSTRACT Privacy preserving data mining is a latest research area in the field of data mining. It is defined as “protecting user’s information”. Protection of privacy has become important in data mining research because of the increasing ability to store personal data about users and the development of data mining algorithms to infer this information. The main goal in privacy preserving data mining is to develop a system for modifying the original data in some way, so that the private data and knowledge remain private even after the mining process. In this paper we propos a system that used PAM (partitioning around medoid) clustering algorithm in health datasets in order to generate set of clusters, then we suggest protecting the sensitive attributes in each cluster in order to increasing the privacy of users information. Protecting the sensitive attributes is done by using privacy techniques through modifying the data values (attributes) in the dataset. We suggest using randomization techniqueData copying (which is a new suggested technique in this paper) to prevent attacker from concluding users privacy information. After modification, the same clustering algorithm is applied to modified data set to verify whether the sensitive attributes are hidden or not. Experimental results on these proposed techniques prove that the PAM algorithm is efficient for clustering in all data sets and the selected clusters are protected efficiently by using Data Copying technique. This technique is applied to Wisconsin breast cancer and diabetes data set. Finally the results of the proposed system prove that the distortion of data can be reduced when the privacy ratio was increased. These are important issues in PPDM, therefore the proposed system is highly successful in achieving the protection of privacy.

Abstract Background: Method optimization of drug analysis is an arising approach among multidisciplinary science fields. The High performance liquid chromatography (HPLC) has been approved to be the cornerstone of drug analysis. Over the last ten years, HPLC has been figured as the analysis method of choice for many compounds. HPLC system has been utilized in diversified applications such as: the quantitative/qualitative analyses of biological samples, calculating the amounts of active pharmaceutical ingredient (API), isolating specific components from their mixtures, and many others. This work aims to qualify and quantify the caffeine in two different pharmaceutical formulas namely; Panadol® Extra tablets and Thicker Fuller Hair® shampoo employing RP-HPLC. Methods: Isocratic method was utilized with fixed mobile phase ratio as methanol: water (40:60). The flow rate was 0.8 ml/min while the wavelength was 273nm. Calibration curve was plotted via the utilization of the following concentrations (0.0, 20, 40, 60, and 80) µg/ml. Thirty six caffeinated tablet samples were examined as dissolved by methanol and filtered with 0.22 µm nylon-membrane syringe filter and diluted. On the other hand three independent caffeinated shampoo samples were examined. The samples were diluted, shacked, and filtered with 0.22 µm nylon-membrane syringe filters. Finally, the diluted solutions were injected to the RP-HPLC and the data was observed and recorded. Results: The areas required to plot the calibration curve were observed. The caffeine peak was identified within each pharmaceutical sample. Consequently the identified peaks were also quantified. The mean content of caffeine in caffeinated tablets was found to be 64.96 mg. Moreover, the caffeine concentration in the shampoo was observed as 0.0047%. Discussion and conclusion: In this work the RP-HPLC has been utilized in the qualification and quantification of caffeine in two different pharmaceutical formulas namely; Panadol® Extra tablets and Thicker Fuller Hair® shampoo. HPLC technology has matured to the extent that almost any existing drug can be analyzed by an existing method that can be found in the analytical literatures. For future work other drugs can be examined or even multidrug formulas can be tried with such accurate and precise RP-HPLC technique.
