Implementing a Distributed Certificate Authority Using Elliptic Curve Cryptography for Big Data Environment

Abstract: Improving security is necessary to secure the exchange of confidential documents and protection against unauthorized accesses in the big data environment. Sharing data across a large-scale distributed system by a group of non-trusted parties can lead to illegal modification and unauthorized access. Thus, a secure and fast authentication service to authenticate the user connecting to the system is imperative. Based on Elliptic Curve Cryptography (ECC), a Distributed Certificate Authority (DCA) scheme has been designed and implemented which can efficiently improve the authentication of big data in a distributed environment. The role of authentication is distributed amongst the many nodes included in groups. Each group has its own revocation and signature list instead of each node, and this way reduces system overhead and avoids consuming much time when verifying the nodes without a centralized server. The proposed scheme is demonstrated on a big dataset of social networks. The scheme has been analyzed on the basis of security criteria and compare it with previous schemes to evaluate its performance. The experiment shows that the proposed scheme is capable of consumes less memory and reduces time consumption.

A Training Program for Physics Teachers Based on Self-learning Strategies and Its Effect on Their Technological Enlightenment and Productive Thinking.

Abstract: This paper aims to construct a proposed training program according to self-organized learning strategies for physics teachers and its effect on their technological enlightenment and productive thinking. The sample consists of (32) teachers and schools; (16) teachers as an experimental sample and (16) as a control sample. The tools are prepared, which are the Enlightenment Technology Scale, which was adopted by (Faez, 2016) consisting of (60) items. The Researchers have prepared the Productive Thinking Test, which consists of two domains: the Critical Thinking Field, which consists of (15) and the Creative Thinking Domain consisting of (9) situations. The stability of productive thinking is (0.88), and the results show that the proposed training program, according to some self-organized learning strategies, meets the training needs of the trainees with remarkable effectiveness to improve the level of their teaching and educational technological performance and achieve the desired goals. The training is influential in bringing about the transfer of training to their students in developing their attitudes towards self-learning. The recommendations are to; apply the training program to the applied students in colleges, reduce the burden on physics teachers, reduce the fear of physics and increase the efficiency of teaching and learning.

Inspection the Linkage between Bovine GDF9 SNPs and Calving Rate (Superovulation) in Holstein Friesians Cows

Abstract: This study prepared to explore the relation between Growth Differentiation Factor 9 (GDF9) genotypes and calving rate, Follicle-stimulating hormone (FSH) and Estradiol (E2) in Iraqi Holstein Friesians breed. Fifteen blood samples collected from a mother of DZTB (with high calving rate records), another blood sample collected from 15 SB cows, the DNA extracted and six primers designed for PCR and sequencing analysis. The FSH and E2 level tested through estrus phase for the two groups (10 n for each group). The sequence evaluation revealed that presence 2 single nucleotide polymorphisms (SNPs) in exon II; A (1109) T and G (1133) A. The genotypic frequency for mutant genotypes was higher significantly (P<0.01) in DZTB cows (with calving rate) than wild at the same loci. On the other hand, the wild genotypes recorded higher significant increment (P<0.01) for SB cows when compared with mutant genotypes in the same loci. Moreover, a significant rise (P<0.05) was reported in E2 and FSH levels for DZTB cows and mutant genotypes (P<0.01) against SB cows and wild genotypes respectively in 0 and 24 h of estrus phase. Non-significant differences recorded in E2 concentration between the same genotypes at same period. In conclusion, the GDF9 exon II SNPs increase the calving rate in Holstein Friesians cows. The blood FSH and E2 concentrations are higher in the mother of DZTB may control the superovulation. Finally, these SNPs can be considered as markers to accelerate the breeding programs and used in embryo transfer and in vitro embryo production for Iraqi Holstein Friesians cows breed.

The Effect of Constructing and Using Training Program for Physics Teachers-Fallujah University on Using the Virtual Labs to Their Technical Enlightenment

Abstract: The current research aims to find The effect of constructing and using training program forphysics teachers-Fallujah university on using the virtual labs to their technical enlightenment by testing the following hypotheses: 1- There is no statistically significant difference at the level of 0.05 indicative between the average grades of teachers of Fallujah University before and after training on the use of virtual laboratories on the technical enlightenment scale. 2- There is no statistically significant difference at the level of 0.05 between the average grades of the Teachers of Fallujah University who have undergone the training program on the use of virtual laboratories and who have not been trained on the technical enlightenment scale.

Synthesis of Chitosan –g-Acrylamide-Co-Acrylic Acid /Ag Nanocomposite For Extended Wound Healing Application

Abstract: New nanocomposite based on chitosan and acrylamide and silver nanoparticles has been prepared to produce wound dressing has superior properties as heamostatic and antibacterial activity. Chitosan successfully grafted with acrylamide via free radical copolymerization using potassium persulphate. Four different chitosan grafted acrylamide prepared and fully characterized through nitrogen content and ATR/IR. Cs-g- PAAM partially hydrolyzed at basic condition in presence of silver nitrate in order to prepare Cs-g-PAAm-co-PAAc/Ag nanocomposite. The optimum condition for preparing homogenous and well distributed was examined using grafted polymers were characterized using TEM and UV-vis absorption. Cs:PAAm (1:1) showed homogenous spherical silver nanoparticles and distributed particles lying at nano size range between 10-30 nm.
