Educational Ethics in Academic Environment: Medical Students' Perspectives

Background and Objective: Educational ethics imply values such as honesty, reliance on one's own personal effort, not to abuse the efforts of others, and respect the dignity and respect for others. Students are faced with different situations in which they show various moral and immoral behaviors. This study aimed to explore medical students' viewpoints and experiences at Golestan University of Medical Sciences about ethics in academic environment in 2013. Materials and Methods: In this qualitative study a purposive sampling was used with maximum variation and 12 medical students participated in the research. Data was gathered using semi-structured interviews. At least an open question "When I say ethics in education or educational environment, what comes to your mind" was repeated in all the interviews. The interviews recorded and transcribed line by line and then analyzed according to "conventional content analysis" method. Results: "Respecting teacher dignity", "preserving dignity of classroom", "respecting and maintaining dignity for classmates", "seeking for knowledge and sciences” emerged as the main themes of the current study. Conclusion: University students considered learning environment as a sacred place; conforming its expected rules and ethics would be mandatory. Abnormal behavior causes not only loss of students dignity but also could be harmful to the calmness of educational atmosphere and may evoke different unpleasant pessimistic ideas about such academic environment

Derivation subalgebras of Lie algebras

Let $L$ be a Lie algebra and $I,$ $J$ be two ideals of $L$. If \Der_J^I(L) denotes the set of all derivations of $L$ whose images are in $I$ and send $J$ to zero, then we give necessary and sufficient conditions under which \Der_J^I(L) is equal to some special subalgebras of the derivation algebra of $L$. We also consider finite dimensional Lie algebra for which the center of the set of inner derivations, Z(\IDer(L)), is equal to the set of central derivations of $L$, \Der_z(L), and give a characterisation of such Lie algebras

Synthesis and Optimization of Reversible Circuits - A Survey

Reversible logic circuits have been historically motivated by theoretical research in low-power electronics as well as practical improvement of bit-manipulation transforms in cryptography and computer graphics. Recently, reversible circuits have attracted interest as components of quantum algorithms, as well as in photonic and nano-computing technologies where some switching devices offer no signal gain. Research in generating reversible logic distinguishes between circuit synthesis, post-synthesis optimization, and technology mapping. In this survey, we review algorithmic paradigms --- search-based, cycle-based, transformation-based, and BDD-based --- as well as specific algorithms for reversible synthesis, both exact and heuristic. We conclude the survey by outlining key open challenges in synthesis of reversible and quantum logic, as well as most common misconceptions.Comment: 34 pages, 15 figures, 2 table

Therapeutic effects of Crocus sativus: An overview of systematic reviews

Background and aims: Traditionally, plants have long been applied in the treatment of various diseases throughout the history of human life. The antimicrobial activity of plant extracts in the laboratory is studied on Gram positive and negative strains of human infectious agents. The aim of this study was to evaluate the antibacterial activity of Mentha longifolia against important human pathogens. Methods: This was an experimental study and no statistical method was used. The antimicrobial effect of ethanol extracts of Mentha longifolia were investigated on Salmonella typhimurium were determined using broth microdilution method. The broth microdilution method was used to determine the Minimal Inhibitory Concentration (MIC) and the Minimum Bactericidal Concentration (MBC). All tests were performed in Mueller Hinton broth supplemented with Tween 80 at a final concentration of 0.5%. Results: The results showed that the lowest MIC concentration was 5 mg/ml that 1 strain of Salmonella was inhibited. The highest and the lowest MBC values of extract were 40 and 10 mg/ml, respectively. Conclusion: Since the antibiotic resistant bacteria are increasing in the world, replacing the chemical and synthetic antibiotics with natural products is essential. It can be concluded from the results of this study that using herbal plant instead of antibiotics can resolve some antibiotic resistant problems

BIT-VO: visual odometry at 300 FPS using binary features from the focal plane

Focal-plane Sensor-processor (FPSP) is a next-generation camera technology which enables every pixel on the sensor chip to perform computation in parallel, on the focal plane where the light intensity is captured. SCAMP-5 is a general-purpose FPSP used in this work and it carries out computations in the analog domain before analog to digital conversion. By extracting features from the image on the focal plane, data which is digitised and transferred is reduced. As a consequence, SCAMP-5 offers a high frame rate while maintaining low energy consumption. Here, we present BITVO, which is the first 6-Degrees of Freedom visual odometry algorithm which utilises the FPSP. Our entire system operates at 300 FPS in a natural environment, using binary edges and corner features detected by the SCAMP-5

GB virus C viremia and anti-E2 antibody response among hemodialysis patients in Gorgan, Iran

Background: GB Virus C is a blood-borne virus and a member of Flaviviridae, like hepatitis C that is distributed globally and puts hemodialysis patients at high risk of developing liver disease. The clinical significance of GBV-C in this population remains unclear

Antioxidant activity of the methanolic extracts of some species of Phlomis and Stachys on sunflower oil

Antioxidant effects of the methanolic extract of Phlomis bruguieri, P. herba-venti, P. olivieri, Stachys byzantina, S. inflata, S. lavandulifolia and S. laxa were tested in sunflower oil stored at 70ºC, by measuring peroxide values after regular intervals and compared with rosemary-, green tea- and BHAcontaining samples. The methanolic extracts of P. bruguieri and S. laxa were found to be most effective in stabilizing sunflower oil
