Space group revsion of the triclinic polymorph of salicyl­aldehyde azine

The structure of the title compound, C14H12N2O2 {systematic name: 2,2′-[hydrazinediylidenebis(methanylyl­idene)]diphen­ol}, has already been determined in the triclinic space group P with Z = 4 [El-Medani, Aboaly, Abdalla & Ramadan (2004 ▶). Spectrosc. Lett. 37, 619–632]. However, the correct space group should be P21/c with Z = 4. This structure is a new polymorph of the already known monoclinic polymorph of salicyladehyde azine, which crystallizes in space group P21/n with Z = 2. The benzene rings form a dihedral angle of 46.12 (9)°. Two intramolucular O—H⋯N hydrogen bonds occur

Prevalence of Smoking among Male Medical Students at Majmaah University, Saudi Arabia

Smoking is defined as burning dry tobacco leaves and inhaling smoke from the burn. This process may be done using different forms of tobbaco products, including cigarettes (Cigars, Little Cigars, Cigarillos), electronic cigarettes, and hookah (shisha). Smoking can give rise to lung diseases such as chronic obstructive pulmonary disease (COPD) and has been proven to be the underlying cause in  84% of deaths in lung cancer and 83% mortalities in COPD. This study was conducted to determine the prevalence of tobacco smoking among male students of the Majmaah University, Saudi Arabia. This cross-sectional study was performed from January to February 2020 on among medical students of Majmaah University, Saudi Arabia. A pretested questionnaire was used to collect data while the SPSS was used for data analysis. From 256 male medical students, only 113 responded to the questionnaire. The prevalence of smoking was found to be 19.5% (n=22) with most smoked cigarettes (50%). Most smokers (50 %) were in the lowest age group, 19-21 years. There was an increase in smoking with an increase in income. Of the 22 respondents who smoked, 10 started smoking when they were 14 to 17 years old. In conclusion, the study shows a low prevalence of smoking among male medical students in the College of Medicine of Majmaah University. Most smokers consume cigarettes, and the majority are not considering quitting

Medical students' perceptions of complementary and alternative medicine therapies: A pre- and post-exposure survey in Majmaah University, Saudi Arabia

Background: Evidently, Complementary and Alternative Medicine (CAM) is increasingly a recognized medical practice that efficiently uses multiple treatment therapies and techniques in promoting the health  and wellbeing of people as well as preventing and managing a variety of human disorders. Research in CAM, which courses exposure to diverse healthcare professionals, is important from many perspectives including improvement in teaching skills of faculty, enhancing capacity building, and  innovative curriculum development. This pre- and post-design crosssectional study aimed to assess perceptions, training needs, personal usage, use in office practice, and knowledge of two batches of medical students toward CAM therapies in Majmaah University, Saudi Arabia.Materials and Methods: The second year medical students of the first (year 2012-13) and second (year 2013-2014) batch [n=26 & 39, respectively] were selected for this study. A reliable 16-item  self-administered questionnaire was distributed among all students for answering before and after the 48-hour specific 19 CAM therapies course, in terms of CAM therapies are clearly conventional or  alternative, training needs, effectiveness, personal use, use in practice, management of two clinical cases by CAM or conventional therapies, and views about which evidence based approach strongly support individual CAM modalities.Results: Medical students' knowledge and perceptions of CAM therapies significantly improved across some sub-items of CAM questionnaire with a positive trend in the rest of its items including their views about CAM therapies, need for further training, personal use of therapies and advising patients regarding CAM practices strongly supported by randomized clinical controlled trials and published case studies.Conclusion: CAM course tends to have positive impact on the knowledge and perceptions of medical students, in addition to need for further training, and personal use and use of CAM therapies in practice in line with strong evidence-based data regarding therapeutic efficacy. The preliminary results of this study call for further research in specific CAM modalities with a larger sample in academic settings across the nation.

MEDICAL STUDENTS' PERCEPTIONS OF COMPLEMENTARY AND ALTERNATIVE MEDICINE THERAPIES: A PRE- AND POST-EXPOSURE SURVEY IN MAJMAAH UNIVERSITY, SAUDI ARABIA

A Visual Query Facility for Multimedia Databases

Multimedia databases store large data objects with complex spatial and temporal relationships. For users to easily and effectively access and make use of this large information space, there is a need for an interactive user interface to act as an intermediary between the database and the user. Many existing multimedia systems provide a browsing-based user interface for their users. However, with large information spaces, browsing does not provide an efficient mechanism for accessing the database. Thus, there is a need for a query facility which enables users to pose queries to the database, and, directly, retrieve information of interest. This research determines the user interface requirements of multimedia information systems and provides a template solution. That is, it presents an easy and efficient way of accessing a multimedia database. This is achieved through a visual query facility which provides a rich visual query interface as well as a browsing facility. The visual query fa..

Support for Document Entry in a Multimedia Database

This Technical Report describes a document entry system that supports the automatic insertion of documents with arbitrary types into a multimedia database. The documents conform to the international standards of SGML and HyTime. This is achieved by instantiating objects in the database to represent the document components. These are persistent objects that can be queried and retrieved using a query interface. To achieve this goal, the database has to be queried dynamically to retrieve meta-information about the document structure. A generic meta type system was designed to model such meta-information. This type system consists of a number of built-in types that model the characteristics common to SGML document components. Whenever support for a new class of documents is added to the system, meta types modeling the characteristics specific to this class are dynamically generated and added to the meta type system. To insert documents conforming to this class into the database, two system..
