Geometrical profile of cohesive-frictional soil slopes for optimal stability
: In this study, finite element method with strength reduction technique is employed to study the stability of slopes with non-straight line profiles comprises three segments. According to this method, the strength parameters are reduced until the slope becomes on the verge of failure. A software called (Optum G2) is used to analyze the geometrical and mechanical parameters. The effect of the geometrical shape of the slope with specific limitations on the factor of safety (FOS) has been investigated to find the corresponding profile configuration that provides maximum stability. The profile (slope face geometry) has been divided into three straight lines (segments) with different lengths. The study involved the soil cohesion (c), angel of internal friction (∅) and the angle of the imaginary straight line linking the slope toe with slope crest (β) called herein slope inclination. The main results showed that using the three segments facing profile can increase the factor of safety (FOS) by up to 15% in comparison with the corresponding slopes of straight line profile. Design charts has been introduced to be utilized by engineers and practitioners to obtain the geometrical parameters for the optimal profile as well as the expected improvement percentage in factor of safety
A Novel Image Encryption Using an Integration Technique of Blocks Rotation Based on the Magic Cube and the AES Algorithm
In recent years, several encryption algorithms have been proposed to protect
digital images from cryptographic attacks. These encryption algorithms
typically use a relatively small key space and therefore, provide safe,
especially if they are of a dimension. In this paper proposes an encryption
algorithm for a new image protection scheme based on the rotation of the faces
of a Magic Cube. The original image is divided into six sub-images and these
sub-images are divided amongst a number of blocks and attached to the faces of
a Magic Cube. The faces are then scrambled using rotation of the Magic Cube.
Then the rotated image is fed to the AES algorithm which is applied to the
pixels of the image to encrypt the scrambled image. Finally, experimental
results and security analysis show that the proposed image encryption scheme
not only encrypts the picture to achieve perfect hiding, but the algorithm can
also withstand exhaustive, statistical and differential attacks
A study on the transferable skills of the engineering students at Universiti Tun Hussein Onn Malaysia
The purpose of this study was to identify the students' levels of awareness of the importance of transferable skills and the mastery of the aspects of adaptive, critical thinking, and problem-solving. In addition, this study also aimed to identify differences in students' levels of awareness of the importance of transferable skills and the difference levels of awareness between male and female students. Research method used in this study was quantitative survey by using questionnaire. Data were analysed by finding the mean and an independent t-test. The results showed that students' levels of awareness of the importance of transferable skills and the mastery levels of these skills were at a high and there were significant differences between female and male students' levels of awareness of the importance of transferable skills. However, the analysis showed no difference in the levels of dominance. Overall, greater awareness will help students to master the skills perfectly. It can also be used as a guide for students to identify elements and features that are required by employers nowaday
A Contrastive Analysis of Haplology Patterns in Modern Standard English and Modern Standard Arabic
Phonologically speaking, each word in a language consists of one or more syllables. In both modern standard English (henceforth MSE) and modern standard Arabic (henceforth MSA), a syllable may be followed by an identical one. In this case, one of such syllables is eliminated. This phonological process is referred to as haplology. The present study aims at finding out similarities and differences of haplology patterns between MSE and MSA. Accordingly, a comparison of haplology patterns between such two languages has been conducted. This phonological phenomenon results in the fact that differences are more than similarities of such patterns between both languages. Additionally, it appears that all eliminated syllables in MSE consist of onset and centre without coda and that they occur only in a medial position. As far as MSA is concerned, all elided syllables consist of onset and centre except the syllables [?it] and [zil] which consist of onset, centre and coda, and the syllables [un],[an] and [in] which consist of a centre and coda without onset. Some of such syllables can occur initially, others medially and that most of them occur finally. Such results lead to the conclusions that haplology patterns are mentioned to make pronunciation easy and that elision of some syllables in certain contexts investigates musical rhythm

The role of 6-0-sulphated heparan sulphate in chronic renal fibrosis
PhD ThesisHeparan sulphate (HS) plays crucial roles during the genesis and resolution of inflammation by sequestration, stabilization and presentation of proinflammatory cytokines and growth factors. The interaction between many of these factors and HS is critically dependent on the variable distribution of anionic 6-O-sulphated glucosamine residues within the structure of HS. The pattern of 6-O-sulphation is generated during HS biosynthesis by HS-6-O-sulphotransferases (HS6STs) but can be modified later by cell-surface HS-6-O-endosulphatases (SULFs). This study was designed to examine the potential contribution of these enzyme families to renal fibrosis following chronic inflammation.
Initial experiments showed that the fibrogenic cytokine TGF-β induced SULF2 expression by renal tubular epithelial cells. Immortalized renal tubular epithelial cells were transfected to constitutively overexpress either HS6ST1 or SULF2 in order to examine the effect of these enzymes on cytokine function. Cells which overexpressed HS6ST1 showed increased binding of FGF2 compared to mock transfected control cells; this FGF2 binding correlated with increased pERK expression and enhanced cell proliferation. The requirement for HS for these processes was validated by inhibition of FGF2 binding with soluble HS, heparin or heparitinase III, whilst the importance of HS sulphation for increased binding was demonstrated after treatment of the cells with chlorate. Structural analysis of 35S-labelled HS from HS6ST1 overexpressing cells demonstrated an increase in mono-6-O-sulphated disaccharides accompanied by a decrease in 2-O-sulphated iduronic acid. By contrast, SULF2 transfectants showed reduced FGF2 binding, ERK activation and proliferation. Structural analysis of 35S-labelled HS from these cells showed a 50% reduction in 6-O-sulphation with a parallel increase in mono-2-O-sulfated iduronic acid.
The significance of the in vitro study for renal fibrosis was then examined using a murine unilateral ureteric obstruction (UUO) model. Immunochemical analysis of UUO kidney sections showed a significant increase in expression of epitopes containing N- and 6-O sulphated HS around the renal tubules. This change was accompanied by a 5-fold increase in expression of the SULF1 gene. In summary, this study suggests that modulation of the expression of sulphate at the 6-O position in HS plays a significant role in the progression of chronic renal fibrosis by alteration of the biological activity of fibrogenic growth factors.Aleppo University and the ministry of Higher Education at the Syrian Arab Republic Research Fun

AMBIGUITY ON SYARIAH TOURISM IN INDONESIA
Purpose: The purpose of this study is to analyze the readiness of tourist destinations through the perception of tourists and local people in developing sharia tourism in Indonesia. Indonesia has a much tourism area, which is visited by both domestic and foreign tourists. In the tourism area, especially visited by foreign tourists, are often equipped with facilities for entertainment that are not accorded to social norms and clash with religious norms. While Indonesia is the largest Moslem country in the world with 85 percent people are Moslem, therefore some people provoke to implement Islamic Law in tourism area.
Methodology: This study includes descriptive research using a quantitative approach that involved two groups were domestic tourists 110 respondents and 50 respondents from local people. This study, conducted in the Bira Beach area, Bulukumba Regency, South Sulawesi Indonesia. Data was analyzed to find out the point of view of the tourist and local people on Islamic law implementation in tourism area in Bira Beach.
Result: The finding of this study indicated that all domestic tourists and local people strongly support the implementation of Islamic Law in tourism area in Bira Beach.
Implications/Applications: However, if Islamic law was actually implemented in all areas in the Bira Beach area, all respondents in tourist group stated that they would not visit Bira Beach anymore, meanwhile all respondents in local people group expressed doubt, caused to the negative impact on their economic income. Based on this study, it needs an appropriate regulation for tourism in Indonesia that could be implemented for all people without contrary to religious norms
