Internet Addiction has become a public health issue that cannot be neglected. In Jordan, there is a need to investigate this issue among school students. This descriptive correlational study aimed to assess the prevalence of Internet Addition and associated risk factors in Jordanian school students. The participants (N = 716) aged 12–18 years were selected randomly from ten public schools in Amman Governorate in Jordan. Socio-demographical data, patterns of Internet usage, the Young's Internet Addiction Tool (YIAT), the Symptom Checklist-anxiety scale (SCL-anxiety), and the Center for Epidemiological Studies Depression Scale for Children (CES-DC) were used. The findings showed that the prevalence of severe Internet Addiction was 6.3%. The highest prevalence of Internet Addiction was among students with family monthly income >1400$/, their fathers completed elementary education and mothers completed university and higher education, and their academic performance was poor. The friend's home was the favorite place among Internet addicted students. Chatting was the highest reason for Internet Addiction. The students were experiencing anxiety and depression symptoms had the highest prevalence of Internet Addiction (10.3%, 8.2%, respectively). There was a statistically significant relationship between the age, school grade, family income, academic performance, average hours of Internet daily usage during school days and holidays, anxiety, depression, and Internet Addiction. These findings emphasize the importance of developing and implementing interventions such as preventive measures and early diagnosis of Internet Addiction among school students. Furthermore, counseling programs are recommended to increase the awareness of families regarding Internet Addiction and their responsibilities in providing guidance and support for their children. © 2017 Elsevier Ltd

A new uni-planar compact electromagnetic bandgap (EBG) structure is presented. The proposed EBG unit-cell is designed based on the stepped-impedance resonator (SIR) technique. Results show that the proposed EBG structure provides a wide frequency bandgap around the 60 GHz band. Moreover, results show that the proposed EBG unit-cell has further miniaturization factors of 0.79 and 0.66 compared to conventional uni-planar EBG and uniplanar compact (UC-EBG) structures, respectively. © 2016 IEEE.

Design and analysis of millimeter-wave (MMW) mushroom-like, circular-patch electromagnetic band-gap (EBG) structure is presented. The in-phase reflection and band-gap characteristics of the proposed EBG structure are investigated. Results show that the proposed EBG structure has stable reflection properties when normally and obliquely illuminated by a plane wave with different polarizations around the 60 GHz band. In addition, the proposed EBG structure is found to have a band-gap around the same frequency bandwidth. With these properties, proposed EBG structure is suitable to be used as reflectors in antenna applications in orderto increase the gain and improve the radiation characteristics. © 2016 IEEE.

Small and Medium Enterprises (SMEs) continue to struggle to measure the success of their website. This results in ineffective eCommerce activities and the consequent disappointment in recognisable benefits. There is a need for a website operational model offering managers the ability to understand the payoffs from their investment. This paper presents an empirically proven intuitive eCommerce website operational model that offers managers a comprehensive way of understanding their website operation. The model premise is simple: the achievement of operational excellence will lead to improved financial performance. The central task for managers, then, lies in understanding what drives operational excellence and then committing the necessary resources to the development of the drivers. Managerial implications stemming from the empirical findings are also discussed.

The current review was designed to compare between the insulin inhalation systems Exubera and Afrezza and to investigate the reasons why Exubera was unsuccessful, when Afrezza maker is expecting their product to be felicitous. In January 2006, Pfizer secured FDA and EC approval for the first of its kind, regular insulin through Exubera inhaler device for the management of types 1 and 2 diabetes mellitus (DM) in adults. The product was no longer available to the market after less than two years from its approval triggering a setback for competitive new inhalable insulins that were already in various clinical development phases. In contrary, MannKind Corporation started developing its ultra-rapid-acting insulin Afrezza in a bold bid, probably by managing the issues in which Exubera was not successful. Afrezza has been marketed since February, 2015 by Sanofi after getting FDA approval in June 2014. The results from this systematic review indicate the effectiveness of insulin inhalation products, particularly for patients initiating insulin therapy. Pharmaceutical companies should capitalize on the information available from insulin inhalation to produce competitive products that are able to match the bioavailability of subcutaneous (SC) insulin injection and to deal with the single insulin unit increments and basal insulin requirements in some diabetic patients or extending the horizon to inhalable drug products with completely different drug entities for other indications. © 2015 Elsevier B.V.

Hydroxypropyl methylcellulose (HPMC) is employed for a wide variety of pharmaceutical and food preparations. Its applications as viscolizing agent (thickening agent), coating polymer, bioadhesive, in solid dispersion to enhance solubility, binder in the process of granulation and in modified release formulations have been well documented. One other notable use is in the production of capsule shells, replacing the animal derived gelatin in conventional two-piece capsules. The aim of this review is to systemically survey published literature on the HPMC use in capsule shells and resolve questions regarding their suitability as a replacement for hardgelatin capsules. Future refinements in the production and filling of HPMC capsule shells and improvement in their in vivo/in vitro dissolution would ensure their superiority over hard gelatin capsules.

A series of 1,3-oxazole, 1,3-thiazole, isomeric 1,2,4-oxadiazole, 1,3,4-oxadiazole, and 1,2,3,4-tetrazole heterocycles was synthesized. All the compounds shared as a common feature the presence of a 4-hydroxyphenyl substituent. The structures of the synthesized compounds were confirmed by MS, 1H-NMR, and elemental analysis. In vitro antimicrobial activity for all the newly synthesized compounds at concentrations of 200-25 μg/mL was evaluated against Gram+ve organisms such as methicillin-resistant Staphylococcus aureus (MRSA), Gram-ve organisms such as Escherichia coli (E. coli), and the fungal strain Aspergillus niger (A. niger) by the cup plate method. Ofloxacin and ketoconazole (10 μg/mL) were used as reference standards for antibacterial and antifungal activity, respectively. Compounds 15, 16, and 20 showed notable antibacterial and antifungal activities at higher concentrations (200 μg/mL), whereas 17-19 were found to display significant antibacterial or antifungal activity (25-50 μg/mL) against the Gram+ve, Gram-ve bacteria, or fungal cells used in the present study. © 2011 by the authors; licensee MDPI, Basel, Switzerland.

Nowadays, multi-medicament use is increasing in clinical practice, especially, in the treatment of elder patients. Therefore, the pharmacokinetic drug-drug interaction of medicaments, which are expected to be co administrated in clinical practice, seems to be significant. The present review provides an update for the relationship between type of chemical substitution (aliphatic or aromatic) of imdazole-containig drugs and their tendency to affect hepatic metabolizing enzyme cytochrome P450 (CYP). In the present review, examples of different therapeutically used imidazole-containing drugs are highlighted to support the first evidence regarding the relationship between CYP-inhibition and chemistry of imidazole ring system. The informations provided throughout this article are intended to improve the medicinal chemist's knowledge of imidazole-containig drugs that are therapeutically widely applied as agents including histamine H1 receptor antagonists (antiallergics), histamine H2 receptor antagonists (antiulcers), histamine H3 receptor antagonists (management of cognitive disorders and attention-deficithyperactivity-disorder), antivirals, antiHIV, antibacterials, antifungals, anethelmintics, antiemetics, and antihypertensives.

Diagnosing diabetes now includes a new criterion; hemoglobin A1C ≥6.5 % which can have significant implications. This review compares the advantages and disadvantages of using HbA1C as the main diabetic diagnostic test. HbA1C has greater stability and less variability than plasma glucose measurements but may not always reflect glycemic levels of glycaemia. The present cut off value identifies fewer diabetics than glucose-based criteria. HbA1C being more convenient could diagnose more patients but this is not yet proven. When choosing a diagnostic test, the limitations of each test must be clearly understood to use appropriate clinical judgment and consider patient preference. © 2015, The Japan Diabetes Society.

Globalization is irreversible and the Internet is increasingly used to connect people and share information worldwide. The proliferation of digital information allows us to make choices about how we gather information and use technology to enhance learning. This is especially true in an academic environment, where the Internet is often used as a tool to facilitate deeper learning. The focus of this study is to investigate whether and how to use blogs to boost student learning in a traditional learning environment where lecture based (didactic) instructional practices still prevailing. This paper will also look at Al-Ain University of Science and Technology (AAU) student perceptions of the benefits of blogs for enhancing college learning. To explore these issues, Blogging was introduced to students in the Internet Technology class. A combination of one hundred and ninety-nine graduate and undergraduate AAU students answered an online questionnaire exploring their perceptions of blogs as a learning tool. Quantitative and qualitative data was also collected through open-ended questionnaires, student journals and reports, and end-ofclass e-portfolios. All statistical analyses were carried out with SPSS. Results indicate that blogs have the potential to empower and enhance student learning. Student response to using blogs in the course has been overwhelmingly positive.
