For this purpose, much searches has disclosed the route lifetime between source and destination vehicles as an important factor to improve the quality of service in the VANET network. Each solution propose his own technique to determine a stable route based on link lifetime and route lifetime; but they do not determine and select the most stable route between source and destination vehicles during the data packets transmission by selecting the longest route lifetime. For this reason, we propose two protocols that use vehicles’ movement information to determine and evaluate the longest route lifetime as a most stable path for comfort applications in a highway environment. One uses the beacon message and the other does not use it. These new schemes increase the packets delivery ratio, the throughput and decrease the number of error messages generated during the transmission of data packets following of the vehicles density.

Cette charge sera destinee a la conception d'un banc de caracterisation experimentale pour les antennes de chauffage, qui ne fonctionnent qu'en presence du plasma de fusion. Apres l'analyse de l'interaction electromagnetique de l'antenne chargee par le plasma de Tokamak, nous montrons qu'un milieu dielectrique tensoriel uniaxe homogene produit les memes interactions avec l'antenne. L'objectif est alors de concevoir un materiau reproduisant les memes proprietes electromagnetiques que ce plasma homogene. Une premiere etude d'un reseau classique de fils metalliques montre l'impossibilite de mettre en œuvre de cette technique pour synthetiser les proprietes EM du plasma. Une seconde etude synthetise le tenseur dielectrique du plasma homogene a partir d'un metamateriau multicouche a la frequence 3. 7 GHz.

Our aim was to identify the most potent predictive factors of survival in Egyptian HCC patients receiving curative or palliative treatments. This retrospective study included 1302 HCC patients attending the HCC multidisciplinary clinic, Cairo University, between February 2009 and December 2016. Clinical, laboratory, tumor characteristics, and treatment data were collected. Prognostic scores for each of the treatment categories, curative or palliative, were developed using routine laboratory tests. Patients were predominantly men, mean age 57.79±7.56 years. All cases developed HCC in addition to cirrhosis, mainly hepatitis C virus-related (88.2%). Most of the patients were Child-Pugh A (56.8%) or B (34.4%) and had single lesions. Transarterial chemoembolization was the most common...

Nowadays, a large proportion of treated patients have cirrhosis with a retained possibility to develop hepatocellular carcinoma (HCC) even after complete cure. We aimed to study tumoral differences between patients who developed HCC after DAAs as either a recurrence or de-novo HCC. We retrospectively analyzed 89 patients who presented to our HCC multidisciplinary clinic with HCC lesions following DAA therapy. A total of 45 patients had complete response to HCC according to the modified Response Evaluation Criteria in Solid Tumors before DAAs intake. Another 44 patients developed de-novo lesions after DAA treatment. Both groups were compared regarding their baseline characteristics, tumor criteria, response to DAAs as well response to HCC treatment. Both groups showed no significant difference regarding their baseline characteristics (age, sex, Child-Pugh score, and performanc...

The extract showed activity against Candida albicans. Six new bengazoles (1-6) and a new bengamide, named bengamide L (16), in addition to the known bengazoles (7-11), bengamides A (12), B (13), E (14), and F (15), and a lactone (17) are described in this paper. All structures were determined on the basis of spectroscopic studies.

Subjects and Methods: For this study, ten completely edentulous participants were selected. Each participant received two dental implants at mandibular canine regions. They were divided into two equal groups: Group I: Each patient received overdentures with bar/locator attachment. Group II: Each patient received overdentures with bar/ball attachment. The vertical marginal bone loss was evaluated using digital peri-apical radiographs over 5-year period. Results: There was a statistically insignificant difference between group I and group II in vertical marginal bone loss after 1 year. However, after five years follow up there was a statistically significant difference between both groups as marginal bone loss was found to be more in group I than that in group II. Conclusion: Bar/ball attachment offers better results in vertical marginal bone loss than bar/locator attachment. Bar locator preferred to be used with four-implants overdenture instead of two-implants to decrease bone loss around implants. It is mandatory to perform monitoring follow-up to avoid any harmful effect on implant and/or residual ridge, maintaining the prosthesis/attachment/ tissue relation to assure proper functional load distribution to avoid further bone resorption.

However, distributed representations usually rely on contextual information which prevents them from learning all the important word characteristics. The task of sentiment analysis suffers from such a problem because sentiment information is ignored during the process of learning word embeddings. The performance of sentiment analysis can be affected since two words with similar vectors may have opposite sentiment orientations. The present paper introduces a novel model called Continuous Sentiment Contextualized Vectors (CSCV) to address this problem. The proposed model can learn word sentiment embedding using its surrounding context words. It uses Continuous Bag-of-Words (CBOW) model to deal with the context and sentiment lexicons to identify sentiment. Existing pre-trained vectors are combined then with the obtained sentiment vectors...

This paper presents the performances of perovskite-type oxide LaCrO3 dedicated for hydrogen solid storage using both numerical and experimental methods. Ab initio calculations have been used here with the aim to investigate the electronic, mechanical and elastic properties of LaCrO3Hx (x = 0, 6) for hydrogen storage applications. Cell parameters, crystal structures and mechanical properties are determined. Additionally, the cohesive energy indicates the stability of the hydride. Furthermore, the mechanical properties showed that both compounds (before and after hydrogenation) are stable. The microstructure and storage capacity at different temperatures of these compounds have been studied. We have shown that storage capacities are around 4 wt%. The properties obtained from this type of hydride showed that it can be used for future applications. XRD analysis was conducted in order...

However, its implementation in the SSCM (Sustainable Supply Chain Management) strategy is sophisticated, and the challenges are not explored very well, especially in the Moroccan context. To this end, the chief objective of the current endeavor is to investigate the barriers that hinder the adoption of blockchain technology in SSCM from the Moroccan industry and service sectors’ perspective. Based on a comprehensive literature search and the use of experts’ viewpoints, the barriers affecting the successful implementation of blockchain are classified into three categories called TEO: technological and system, environmental, and intra-organizational dimensions. In this context, a fuzzy group decision-making framework is organized by combining DEMATEL (Decision-Making Trial and Evaluation Laboratory) and IFAHP (Intuitionistic Fuzzy Analytic Hie...

Security of UAV Data Link is still unsatisfactory especially if a strong adversary model is considered. This paper describes a new design of AENOTP, tested for security in UAVs Data Link. AENOTP algorithm combines NOTP with AE technique to ensure encryption and authentication along with data integrity. AE is a technique that ensures the security of the transported data. The design and analysis of AENOTP gives a fast and enhanced stream cipher AE architecture based on the unpredictability concept. Implementation of AENOTP measures encryption and decryption of any sent and received data. AENOTP shows high speed of generating the key stream bits of the OTP stream cipher and high speed of the proposed algorithm of 75 Mbits/sec. It achieves high level of security for any transmitted data. It can easily resist different attacks such as linear and differential attacks.

The therapeutic potential of Phoenix dactilyfera L. pits is offered by their balanced, valuable and diverse phytochemical composition providing protective potential against oxidative reactions, making it a good candidate to treat glucocorticoid-induced osteoporosis (GIO). This study evaluates the possible anti-osteoporotic effect of date pit extract (DPE) against dexamethasone (DEXA)-induced osteoporosis. Male rats were allocated into three control groups, which received saline, low and high doses of DPE (150 and 300 mg/kg/day), respectively. Osteoporosis-induced groups that received DEXA (1 mg/kg/day) were divided into DEXA only, DPE (2 doses) + DEXA, and ipriflavone + DEXA. Femoral bone minerals density and bone mineral content, bone oxidative stress markers, Wnt signaling, osteoblast and osteoclast differentiation markers, and femur histopath...

The gastroprotective potential of pentagalloyl glucose (PGG) against indomethacin-induced ulcer in rats and the possible underlying mechanisms were investigated. Gastric ulceration was induced by indomethacin (single dose, 60 mg/kg). Pretreatment with PGG (100 or 200 mg/kg, orally) for 8 days prior to the administration of indomethacin furnished significant reductions in gastric mucosal lesions as well as a significant increase in mucus concentration. Also, PGG significantly declined the elevations in gastric mucosal MDA, TNF-α, IL-6, PECAM-1, VEGF, and iNOS expression. It also mitigated the decrease in GSH and GPx and eNOS expression observed with indomethacin. The protective effects furnished by PGG were comparable to that of famotidine. The obtained results suggested that the anti-ulcer effects of PGG are mediated by increasing mucus production, scavenging free radicals, decreasing inflam...

Basic model of the PMVM is designed with dual-stator, axial-flux topology, spoke-type magnets array, which has the feature of high torque density and relative high power factor at low speed for the direct-drive systems. Compared to a radial-flux motor, the axial-flux motor has non-equal radii in inner side and outer side, which results in extra design considerations in terms of stator slot shape, rotor core shape, and asymmetric overhang lengths. Therefore, the design parameters of slot shape, winding method, rotor core, and rotor overhang length are discussed based on the basic model of axial-flux PMVM under the constraint of motor volume. Motor characteristics are illustrated and analyzed using three dimensional finite element method (3D FEM). Finally, one prototype of optimal designed model is manufactured and tested to verify the improved motor characteristics.
