- ItemThe analysis of the economic and demographic incentive system in Israel(2001-01-05) RahhalState of Israel had been declared on Palestine at May 15,1948. The new state was established between Arab societies which have different traditions, customs and religions. For developing its economy in this strange environment, Israel offer many incentives for Jews and Non-Jews investors to invest in. At the same time, Israel try to make a demographic balance between Arabs and Jews in Occupied Palestine by emptying Palestine from Palestinian and replace them by Jewish immigrants from around the world using various incentive policies. The main obstacle faced Israeli economy is the political stability which is absence in Palestine. This paper analysed the economic, demographic balance policies and other incentives in detail.
- ItemSustainable Transport Planning for Israel and Palestine(WCTR Society, 2001-07-22) Fürst, Franz; Isaac, Jad; Ishaq, Isam; Kaplan, Jay; Maoh, Hanna; Petzold, Ingo; Plümer, Lutz; Salomon, Ilan; Schürmann, Carsten; Spiekermann, Klaus; Wegener, MichaelThe paper presents the results of a trilateral research project carried out jointly by German, Israeli, and Palestinian institutions. The overall objective of the project was to develop and adapt models and tools for resource-preserving transport planning in the West Bank and the adjacent areas. Because of its high dynamics and the particular political circumstances, broader socio-economic and political considerations needed to be included in the analysis of present conditions and the exploration of future developments in this area. Compared to other countries, transport planning in Palestine is much more linked to sensitive issues such as security, Israeli settlements, bypass road s and checkpoints, which cannot always be separated in a clean way. To evaluate different policy options for transport planning, a modelling system has been developed consisting of a GIS database, integrated transport and environmental models and network extensions tools. The paper pres ents the integrated database and the modelling system developed, describes the scenarios implemented and compares the outcomes of the model runs with respect to their environmental and social impacts.

- ItemSatisfaction with Dental Implants: A Literature Review(Lippincott Williams & Wilkins, 2005) AL- Omiri, Mahmoud; Abu Hantash, Ra'ed O.; AL- Wahadni, A.Recent years have witnessed a consistent trend toward the introduction of patient assessment of different treatment outcomes in dental practice. Patient satisfaction with dental implants was considered among these treatment modalities. Few literature reviews have been published on this topic. This article critically analyzes the concerned topics related to patient satisfaction with dental implant. A MEDLINE search was completed from 1983 to 2004, along with a manual search, to locate related articles on the topic. Dental implants provided promising and predictable results regarding patient satisfaction and various aspects of life assessment. (Implant Dent 2005;14:399–408)
- ItemMicrobial Profiles of On-line–Procured Sprouting Seeds and Potential Hazards Associated with Enterotoxigenic Bacillus spp. in Homegrown Sprouts(Journal of Food Protection, 2005-02-28) Khalid, M. F.; Pao, S.; Kalantari, A.We examined the microbiological quality of sprouting seeds sold through the Internet. Overall, five types of seeds each from six organic and six conventional sources were evaluated. The growth and toxin production of naturally occurring Bacillus spp. in sprouts produced using home-scale sprouting devices also were investigated. For alfalfa, broccoli, lentil, mungbean, and radish seeds, the average microbial counts were 3.3, 4.0, 2.8, 3.5, and 3.6 log CFU/g, presumptive B. cereus counts were 0.7, 1.0, 0.8, 1.0, and 0.9 log CFU/g, and total coliform counts were 20.3, 20.4, 20.5, 0.0, and 20.4 log of the most probable number per gram, respectively. No Salmonella, Escherichia coli O157, other fecal coliforms, or Staphylococcus aureus was found on seeds. Compared with conventional seeds, the organic seeds had lower or equivalent counts for total microorganisms, presumptive B. cereus, and total coliforms. When seeds were sprouting using a glass jar, the growth of presumptive B. cereus was significant for radish and broccoli but not for alfalfa, lentil, and mungbean sprouts; the counts exceeded 5.0 log CFU/g in radish sprouts. When sprouts were grown using an automatic sprouting device, presumptive B. cereus showed slight growth (,3.0 log cycles) in radish, broccoli, and mungbean sprouts but no growth in alfalfa and lentil sprouts. Although the presumptive B. cereus isolates were enterotoxigenic, they did not produce or accumulate detectable levels of diarrheal toxins in freshly produced sprouts.
- ItemPsychological impact on implant patients' oral health‐related quality of life(Wiley, 2006-01-09) Abu Hantash, Ra'ed O.; Al- Omiri, Mahmoud K.; AL- Wahadni, Ahed M.Objectives: The literature has shown that patients' satisfaction with dental prostheses is associated with the existence of certain personality profiles. It is important to study such relationships in dental implant patients. Material and methods: Fifty patients (28 men and 22 women), aged between 22 and 71 years (mean age 43.22 years, SD 12.24 years), who were partially edentulous and were seeking dental implant therapy were entered into this study. The patients were requested to answer two reliable and valid questionnaires – the Dental Impact on Daily Living (DIDL) and the Neuroticism Extraversion Openness Five‐Factor Inventory (NEO‐FFI) – before implant treatment and 2–3 months after prosthodontic rehabilitation therapy. Results: Certain personality traits were found to have a significant relationship with patients' satisfaction with dental implants both before and after implant therapy (P<0.05). Neuroticism score had valuable features in predicting patients' total satisfaction ratings (P=0), satisfaction with appearance dimension (P=0), satisfaction with oral comfort dimension (P=0.005) as well as satisfaction with general performance dimension (P=0). Conclusion: Personality traits have an impact on patients' satisfaction with dental implant therapy. In addition, personality traits provide valuable information for the prediction of patients' satisfaction with their implant‐supported prostheses. Neuroticism, openness, agreeableness and consciousness are very helpful in this regard. Neuroticism was found the main predictor of the patients' oral health‐related quality of life following implant treatment
- ItemUsing Aqueous Chlorine Dioxide To Prevent Contamination of Tomatoes with Salmonella enterica and Erwinia carotovora during Fruit Washing(Journal of Food Protection, 2006-09-15) Khalid, M. F.; Pao, S.; KelSey, D. F.; Ettinger, M. R.Chlorine dioxide (ClO2) is an antimicrobial agent recognized for its disinfectant properties. In this study, the sanitizing effects of ClO2 solutions against Salmonella enterica and Erwinia carotovora in water, on tomato surfaces, and between loads of tomatoes were evaluated. In water, ClO2 at 5, 10, and 20 ppm caused a 5-log reduction of S. enterica within 6, 4, and 2 s, respectively. Higher lethality was observed with E. carotovora; a 5-log reduction was achieved after only 2 s with 10 ppm ClO2. On fruit surfaces, however, the sanitizing effects were compromised. A full minute of contact with ClO2 at 20 and 10 ppm was required to achieve a 5-log reduction in S. enterica and E. carotovora counts, respectively, on freshly spot-inoculated tomatoes. On inoculated fruit surfaces, populations decreased 3 log CFU/cm2 during desiccation at 24 1 C for 24 h. Populations of air-dried Salmonella and Erwinia were not significantly reduced (P 0.05) by ClO2 at 20 ppm after 1 min. Either wet or dry inoculum of these two pathogens could contaminate immersion water, which in turn can cross-contaminate a subsequent load of clean fruit and water. ClO2 at 5 ppm used for immersion effectively prevented cross-contamination. Pathogen contamination during fruit handling is best prevented with an effective disinfectant. Once a load of fruit is contaminated with pathogens, even a proven disinfectant such as ClO2 cannot completely eliminate such contaminants, particularly when they are in a dehydrated state on fruit.

- ItemPrevalence, Clinical Picture, and Risk Factors of Dry Socket in a Jordanian Dental Teaching Center(2007-03) Nuseir, Y.; Abu Younis, Mohammad H.Aims: The aims of this study were to determine the prevalence, clinical picture, and risk factors of dry socket at the Dental Teaching Center of Jordan University of Science and Technology (DTC/JUST). Methods and Materials: Two specially designed questionnaires were completed over a four-month period. One questionnaire was completed for every patient who had one or more permanent teeth extracted in the Oral Surgery Clinic. The other questionnaire was completed for every patient who returned for a post-operative visit and was diagnosed with dry socket during the study period. Results: There were 838 dental extractions carried out in 469 patients. The overall prevalence of dry socket was 4.8%. There was no statistically significant association between the development of dry socket and age, sex, medical history, medications taken by the patient, indications for the extraction, extraction site, operator experience, or the amount of local anesthesia and administration technique used. The prevalence of dry socket following non-surgical extractions was 3.2%, while the prevalence following surgical extractions was 20.1% (P< 0.002). The prevalence of dry socket following surgical and non-surgical extractions was significantly higher in smokers (9.1%) than in non-smokers (3%) (P = 0.001), and a direct linear trend was observed between the amount of smoking and the prevalence of dry socket (P = 0.034). The prevalence of dry socket was significantly higher in the single extraction cases (7.3%) than in the multiple extraction cases (3.4%) (P = 0.018). The clinical picture and management of dry socket at DTC/JUST were similar to previous reports in the literature. The prevalence of dry socket, its clinical picture, and management at DTC/JUST are similar to those reported in the literature. Abstract 2 The Journal of Contemporary Dental Practice, Volume 8, No. 3, March 1, 2007 Introduction Dry socket is one of the most common complications of tooth extraction and is characterized by severe pain starting usually on the second or third day postoperatively. Its prevalence has been reported to vary from 0%1 to more than 35%2 and is more common following mandibular third molar extraction. 3-9 Patients experience pain and may experience loss of productivity. This makes the condition costly to both patient and society, as 45% of patients require multiple postoperative visits in the process of managing this painful condition. 10 The exact pathogenesis of dry socket is not well understood. However, disintegration of the blood clot by fibrinolysis remains the most widely accepted theory.11 Several contributing factors have been reported to be associated with an increased risk of dry socket. They include traumatic extraction, 3-4,11 preoperative infection, 11-12 smoking,13 sex, 11,14 site of extraction, 8,14 use of oral contraceptives, 15 use of local anesthetics with vasoconstrictors, 16 inadequate postoperative irrigation, 17 and low level of operator experience. 4,8 Several methods have been advocated to reduce the incidence of dry socket including the use of antiseptic mouthwashes18-20 antifibrinolytic agents, 21 antibiotics, 22-23 steroids, 24 clot supporting agents, 25 and other intra-alveolar dressings and medicaments. 9,27-28 While this condition cannot be completely treated as long as the exact etiology is not firmly established, its management appears to be simple and effective. It usually involves reassurance of the patient, cleaning and irrigation of the affected socket, and insertion of a medicated pack. 2,25,29-30 This is the first study of dry socket at the Dental Teaching Center of Jordan University of Science and Technology (DTC/JUST) and in Jordan . Its aims were to identify the prevalence and risk factors as well as to describe the clinical picture of this painful condition at this Jordanian dental teaching center. Methods and Materials The DTC/JUST was the setting for the study. This center is located in Irbid, in North Jordan, and is involved in the training of undergraduate and postgraduate dental students. It serves the community of the city of Irbid and its neighboring towns and villages, which have a total population of approximately 750,000. This prospective study was totally observational without any interference with any of the clinical procedures normally followed at DTC/JUST. Description of the Sample During the study period, 838 permanent tooth extractions were carried out in 469 patients. There were 225 (48.0%) male patients and 244 (52.0%) female patients. The age of patients Conclusion: Smoking and surgical trauma are associated with an increased incidence of dry socket. Moreover, patients who had single extractions were more likely to develop dry socket than those who had multiple extractions in the same visit

- ItemEvaluation of the Ministry of Health school oral health programme in the West Bank region of Palestine(2007-06-13) E, KateebThis paper reports an evaluation of the activities and outcomes of the school oral health programme conducted by the Ministry of Health in public schools in the West Bank region of Palestine from 1997-98 to 2003-04. Retrospective analysis of official records focused on oral health indices and student referrals. A slight improvement in DMFT scores in students in some governorates in the last 2 years showed some progress in caries control. However, maintenance efforts are required to ensure that caries level does not rise in disease-stable areas, and an increase in strategic effort is required to address the high caries level in high-risk areas. In-depth interviews with stakeholders identified the strengths and weaknesses of the screening programme and recommendations for improvements
- ItemLearning Difficulties in Chemistry: An Overview(2007-06-25) Sirhan, GhassanChemistry is often regarded as a difficult subject, an observation which sometimes repels learners from continuing with studies in chemistry. This paper seeks to bring together the general findings obtained from research over the past few decades for both school pupils and university students in an attempt to suggest the key reasons for this difficulty. Suggestions are made on ways to minimise the problems based on understandings of attitudes and motivation as well as the psychological understandings of how learning takes place.
- ItemDetection of Vapour Emissions from Star Anise Seeds and Mint Leaves using the CO2 Laser Photoacoustic Technique(2007-07-07) Al-Masri, Hasan; Lainé, Derek; Al-Jourani, Mohanned; Abu-Taha, Mohammad; Salem, KhaledThe aim of this work was to establish the feasibility of the detection of the vapours of the star anise and mint essential oils emitted from the uncrushed seeds of star anise (Illicium verum H.) and from the leaves of Japanese mint (Mentha arvensis L.) respectively using a heat pipe type of photoacoustic cell in conjunction with a line tunable waveguide CO2 laser. Infrared photoacoustic stick spectra were obtained with excellent reproducibility and a high signal-to-noise ratio for the vapour emissions in one atmosphere of nitrogen gas over a temperature range from 20°C up to 180°C in the case of anise seeds and from 20°C to 100°C for mint leaves. Significant differences found between the photoacoustic spectra from the vapour emission of seeds and leaves when compared with commercial samples of the related essential oils are discussed.

- ItemMicrobiological quality of frozen "edamame" (vegetable soybean)(2007-07-25) Khalid, M. F.; Pao, S.; Ettinger, M. R.; Mebrahtu, T.; Mullins, C.This study compared the microbiological quality of frozen “edamame” to other varieties of frozen beans sold in Virginia. Furthermore, the reduction of microorganisms during experimental edamame processing was investigated. Commercial frozen in-pod and shelled edamame had aerobic mesophiles at 3.4 and 3.1 log cfu/g, yeasts and molds at 2.3 and 2.1 log cfu/g, and some contained low levels of Escherichia coli and enterotoxigenic Bacillus spp. Salmonellae were not found; however, 5% edamame and 4% frozen beans in general were positive for Listeria monocytogenes. Rinsing and shelling raw edamame caused a 1–2 log reduction of total aerobic mesophile, yeast and mold, and coliform counts. No naturally occurring yeast, mold or coliform was detected after blanching edamame at 98C for 30 s. Blanching for 60 s eliminated approximately 6 log cfu/g of inoculated E. coli and Listeria from in-pod edamame. Adequate processing ensures the microbial quality and safety of frozen edamame.
- ItemTopological modeling of antimycobacterial activity of 3-formyl rifamycin SV derivatives(Arkat USA, 2007-08-27) Deeb, Omar; Singh, Jyoti; Varma, R.G.; Khadikar, Padmakar V.The paper describes topological modeling of antimycobacterial activity of 3-formyl rifamycin SV derivatives using a large series of molecular vis-à-vis topological descriptors. For the set of 53 derivatives of 3-formyl rifamycin SV no one variable model is possible, however, in multiparametric regression excellent model is obtained for modeling the activity. The results are discussed using variety of statistical parameters.
- ItemErrors-In-Variables-Based Approach for the Identification of AR Time-Varying Fading Channels(IEEE SIGNAL PROCESSING LETTERS, 2007-11) Jamoos, Ali; Grivel, Eric; Bobillet, William; Guidorzi, RobertoThis letter deals with the identification of time-varying Rayleigh fading channels using a training sequence-based approach. When the fading channel is approximated by an autoregressive (AR) process, it can be estimated by means of Kalman filtering, for instance. However, this method requires the estimations of both the AR parameters and the noise variances in the state–space representation of the system. For this purpose, the existing noise compensated approaches could be considered, but they usually require a long observation window and do not necessarily provide reliable estimates when the signal-to-noise ratio is low. Therefore, we propose to view the channel identification as an errors-in-variables (EIV) issue. The method consists in searching the noise variances that enable specific noise compensated autocorrelation matrices of observations to be positive semidefinite. In addition, the AR parameters can be estimated from the null spaces of these matrices. Simulation results confirm the effectiveness of this approach, especially in presence of a high amount of noise.
- ItemEliminating Salmonella enterica in alfalfa and mung bean sprouts by organic acid and hot water immersions(Agricultural Research Station, 2007-12-11) Pao, S.; Kalantari, A.; Khalid, M.F.This study evaluated the efficacy of acid and heat treatments for eliminating Salmonella enterica in sprouts grown from inoculated seeds. Salmonella was detected at 7.6 and 6.9 log cfu/g, respectively, in alfalfa and mung bean sprouts after germination. Immersing the alfalfa and mung bean sprouts, respectively, for 24 and 48 h in 2% acetic acid eliminated Salmonella (<1 cell/25 g). In 5% acetic acid, the elimination of Salmonella in alfalfa and mung bean sprouts was achieved after 4 and 16 h, respectively. However, similar treatments by citric acid were ineffective. Dipping alfalfa sprouts in hot water at 70, 80, 90 and 100C, respectively, for 10, 5, 3 and 3 s eliminated Salmonella. For mung bean sprouts, the elimination was observed at 70 or 80C for 20 s, 90C for 10 s, or 100C for 5 s. This study demonstrated that acetic acid and hot water treatments can be effective in inactivating Salmonella for sprout safety.

- ItemComparative QSAR Study on Para-substituted Aromatic Sulphonamides as CAII Inhibitors: Information vs. Topological (distance-based and connectivity) Indices(John Wiley & Sons Ltd, 2008-01-19) Singh, Jyoti; Shaik, Basheerulla; Singh, Shalini; Agrawal, Vijay K.; Khadikar, Padmakar V.; Deeb, Omar; Supuran, Claudiu T.Comparative quantitative structure–activity relationship studies on para-substituted aromatic sulphonamides carbonic anhydrase II (CAII) inhibitors are reported in this paper. The study is made utilizing (i) information indices along; (ii) distance-based and connectivity indices and (iii) combination of information, distance-based and connectivity type topological indices. The study has shown that distance- based and connectivity type indices are superior for modelling, monitoring and estimating CAII inhibition. The results are critically discussed using a variety of statistical parameters. Our results show that starting from the mono-parametric regression itself, our results are superior: Furthermore, our methodology allowed carrying out much higher-parametric regressions, yielding a nine-parametric model with R2 as high as 0.8375. The eightparametric regression, gave R2 = 0.8343. As there is not much difference, we have considered the eight-parametric regression the best.
