KNOWLEDGE ABOUT HEPATITIS B INFECTION AMONG MEDICAL STUDENTS IN ERBIL CITY , IRAQ

Background: Health care personnel especially medical student represent high risk population for hepatitis B virus infection. Objective: This study sought to assess the knowledge of medical students regarding hepatitis B infection and its transmission and prevention. Methods: A cross-sectional study was conducted on 200 medical students in Erbil, the main city of Iraqi Kurdistan region. A self-administered questionnaire was used for data collection. In addition to basic demographic characteristics, the questionnaire included 18 questions about routes and modes of transmission, sequel and prevention of HBV. The students were also asked about their vaccination status. Statistical package for social sciences was used for data analysis. Results: A high proportion of the study participants (41%) had poor knowledge about HBV while 45% had acceptable knowledge and 14% had good knowledge. Good knowledge score was significantly higher among older students and students in clinical year study, p <0.001. Only 45% of them were vaccinated against HBV. The vaccination rate was higher among clinical year study students (68%) in comparison to pre-clinical year students (22%), p <0.001. The vaccination rate was highest among those who had good knowledge (100%), in comparison to those with acceptable knowledge (53.3%) and poor knowledge (17.1%), p <0.001. Conclusions: Knowledge about HBV among the medical students in Hawler Medical University is relatively poor, with important gaps which need to be strengthened. A critical level of public awareness and vaccination coverage, particularly among young students, are essential to decrease burden of the disease in Erbil in the future.
Characterization of genetic diversity of citron watermelon landrace accessions of South Africa through simple sequence repeat markers

ABSTRACT Profiling the genetic diversity of germplasm collections is fundamental for selection programs and strategic conservation. Citron watermelon (Citrullus lanatus var. citroides [L.H. Bailey] Mansf. ex Greb.) is an under-researched cucurbit crop despite providing food and nutritional security in sub-Saharan Africa. There is limited information on genetic relationships of South African citron watermelon accessions for effective breeding. The objective of this study was to determine the extent of genetic diversity among 48 South African citron watermelon landrace accessions using selected simple sequence repeat (SSR) markers to identify genetically divergent accessions for trait integration and variety development. The SSR markers amplified a total of 24 alleles, with a mean expected heterozygosity value of 0.38, indicating moderate genetic diversity among the studied accessions. The mean polymorphic information content value of 0.21 indicated low discriminatory power of the SSR markers. Analysis of molecular variance attributed 8%, 75%, and 17% of the molecular variation between populations, among accessions and within accessions, respectively. Three distinctive genetic groups were identified based on cluster analysis, which aided the selection of genetically diverse citron watermelon accessions for breeding and cultivar development.

Multidisciplinary approach in the management of neurotrauma and its sequelae

It is well known that traumatic brain injury (TBI) can long-term consequences of major public health concern. It can be said that wide spectrum and distinct lesions resulting in variable clinical consequences make the process of post-TBI rehabilitation challenging. A patient who sustains TBI can have variable outcome ranging from complete recovery to persistent vegetative state. Between these two there is a spectrum of TBI related sequel which may be disturbed levels of consciousness, post-traumatic agitation, post-traumatic paroxysmal sympathetic hyperactivity, posttraumatic hydrocephalus, and posttraumatic neuroendocrine dysfunctions all these requiring different rehabilitation programmes and rehabilitation approaches.
A Formulation of Dependent ML with Explicit Equality Proofs

We study a calculus that supports dependent programming in the style of Xi and Pfenning’s Dependent ML. Xi and Pfenning’s language determines equality of static data using a built-in decision procedure; ours permits explicit, programmer-written proofs of equality. In this report, we define our calculus’ semantics and prove type safety and decidability of type checking; we have mechanized much of these proofs using the Twelf proof assistant. Additionally, we illustrate programming in our calculus through a series of examples. Finally, we present a detailed comparison with other dependently typed languages, including Dependent ML, Epigram, Cayenne, ATS, Ωmega, and RSP1. This material is based on work supported in part by the National Science Foundation under grants CCR-0204248: Type Refinements and 0121633: ITR/SY+SI: Language Technology for Trustless Software Dissemination.

Foliar Uptake of Toxic Metals Bound to Airborne Particulate Matter in an Urban Environment

In this research, the foliar uptake patterns of three toxic metals (Pb, Cd, and Cu) bound to airborne particulate matter (PM) were investigated using two evergreen tree species ( Senna siamea and Alstonia scholaris ) at six different locations (two residential, traffic, commercial, and industrial) plus one control site in a subtropical urban environment. The concentrations of Pb, Cd, and Cu were measured from foliar dust, leaf, road dust, and soil samples collected from the target sites over two consecutive years. Their temporal variations in leaves were examined at monthly, seasonal, and annual scales. The data were evaluated statistically by One-way Analysis of variance ANOVA and correlation analysis along with enrichment factor ( EF ). There were significant variations on the monthly as well as the seasonal basis. Accordingly, PM-bound toxic metals in leaves come from an airborne route. In addition, leaves of S. siamea showed a moderately improved accumulation pattern relative to A. scholaris . This study suggests that these plants can be used efficiently as basic tools to assess the pollution and associated behavior of PM-bound toxic metals in an urban environment.
Chinese consumers’ intention to purchase tourism financial products

ABSTRACT With the rapid development of internet finance, building a “tourism + finance” ecosystem is gradually becoming a theme of reform in the tourism industry. In this study, the technology acceptance model (TAM) is used to explore which factors, in addition to perceived usefulness and perceived ease of use, influence consumers’ intentions to purchase tourism financial products. The study conducts a questionnaire survey including basic questions and a Likert scale with 19 indicators covering 5 dimensions. The results are drawn from a structural equation model that supports five out of six proposed hypotheses. The findings suggest that perceived usefulness, perceived ease of use, trust, and perceived risk significantly influence purchase intentions. Additionally, perceived ease of use has a significant impact on perceived usefulness. Suggestions regarding future tourism financial products development are made, and the study’s limitations are discussed.
Using the Guided Fireworks Algorithm for Local Backlight Dimming

Local backlight dimming is a promising display technology, with good performance in improving the visual quality and reducing the power consumption of device displays. To set optimal backlight luminance, it is important to design high performance local dimming algorithms. In this paper, we focused on improving the quality of the displayed image, and take local backlight dimming as an optimization problem. In order to better evaluate the image quality, we used the structural similarity (SSIM) index as the image quality evaluation method, and built the model for the local dimming problem. To solve this optimization problem, we designed the local dimming algorithm based on the Fireworks Algorithm (FWA), which is a new evolutionary computation (EC) algorithm. To further improve the solution quality, we introduced a guiding strategy into the FWA and proposed an improved algorithm named the Guided Fireworks Algorithm (GFWA). Experimental results showed that the GFWA had a higher performance in local backlight dimming compared with the Look-Up Table (LUT) algorithm, the Improved Shuffled Frog Leaping Algorithm (ISFLA), and the FWA.
THE IMPACT OF BUY – SELL RECOMMENDATIONS ON BANKS’ STOCK RETURNS

The aim of this research was to investigate the impact of stock buy-sell recommendations of brokerage houses on the stock returns of banks operating in Borsa Istanbul (BIST). Accordingly, it has been attempted to assess if investors can receive abnormal returns in accordance with the recommendations of brokerage houses using the case study technique. The validity of the semi-strong effective form of investors who made a buying-selling decision based on brokerage house recommendations was investigated. The returns of the banks' stocks were obtained from the data-stream database. The study evaluated buy-sell recommendations for four large brokerage houses and analyzed data from January 2018 through December 2020. The event study method was used, and t-test was performed in order to determine the difference of abnormal returns from zero in the research. As a result of the research, a negative abnormal return was determined on the day of the event and the day after the sell recommendation was given. Besides, a positive abnormal return was determined on the day before the announcement and on the day of the event in the bank stocks on which buy recommendation has been given. In this respect, the average abnormal and cumulative abnormal returns indicated that BIST was not an efficient market in a semi-strong form for the banking sector. When the sell recommendations and their effects are examined within the scope of the research, it is seen that the day before [-1] p=0.016 value was obtained, on the day, [0] p=0.018 value was obtained, the next day and two days later [+1, +2] p=0.077 and 0.046 values were obtained. On the other hand, when the buy recommendations and their effects are examined, it is seen that the day before [-1] p=0.000 and on the day [0] p=0.098 values were obtained. T-test results and p values show that brokerage house recommendations are effective on stock returns in the BIST banking sector, and therefore BIST banking sector is effective in a weak form. The obtained results of the study were crucial for investors who invested in short-term stocks.
Left Main Coronary Artery Disease : CABG is superior to PCI

Left main coronary artery disease (LMCAD) is a special part of coronary pathology and its gold standard treatment is coronary artery bypass surgery (CABG). Over the last two decades, the evolution in technology and materials and the growing experience of interventional cardiologist treating acute coronary syndrome improved the results of percutaneous coronary interventions even in patients with LM disease. Recent prospective randomized studies though (SYNTAX) as well as large registries comparing the two methods showed comparable results concerning safety and inferiority of PCI regarding restenosis and need for reintervention. Up to now CABG remains the treatment of choice for LM disease with PCI being a reliable alternative solution in cases of patients of high surgical risk. The above is strongly recommended by the new guidelines. I N T R O D U C T I O N Cardiovascular disease is by far the first cause of death in the western world. The prevention and the reduction of cardiac risk factors have beneficial results in the general population, moving the main problem to more elder group of people. Coronary-artery bypass grafting (CABG) was introduced in 1968 and rapidly became the standard of care for symptomatic patients with coronary artery disease. Advances in coronary surgery (e.g., off-pump CABG, smaller incisions, enhanced myocardial preservation, use of arterial conduits, improved postoperative care as well as widely published surgical outcomes) have reduced morbidity, mortality, and rates of graft occlusion. The rate of mortality at a global level is less than 2% and in most recent studies it is less than 1.3%, including emergency and complex cases. The incidence of left main (LM) coronary artery disease (LMCAD) among patients undergoing coronary angiography ranges from 4% to 6%. The same percentage for those undergoing surgery is as much as 30%. Although uncommon, LMCAD is a constant topic of discussion between cardiac surgeons and interventional cardiologists. This discussion began in 1975, when Gorlin and Cohen first compared a surgical approach for LM stenosis to any other treatment option and reported that CABG showed significant benefits. Since then and for over 45 years researchers are trying to find alternative and less CARDIOVASCULAR SURGERY UPDATE 1 Cardiac Surgery Department, Evagelismos Hospital, Athens, Greece Anesthesiology Department, Evagelismos Hospital, Athens, Greece HOSPITAL CHRONICLES 2012, VOLUME 7, SUPPLEMENT 1: 146–152
Effect of next nearest neighbour interactions on compensation temperature in trilayered spin systems

ABSTRACT In this paper we are communicating a Monte-Carlo based numerical study on the ABA type trilayered Ising spin system incorporating next nearest neighbour interactions. The ABA type system is of growing interest because of the existence of compensation temperature. The effect of next nearest neighbour interactions on compensation temperature and phase transition have been studied by focussing on thermal response of some thermodynamic quantities using the Metropolis algorithm. An effort also made to understand the role of intralayer and interlayer interactions in controlling compensation temperature and critical temperature within such a system.
Trimethylamine N-Oxide Reduces the Susceptibility of Escherichia coli to Multiple Antibiotics

Trimethylamine N-oxide (TMAO), an important intestinal flora-derived metabolite, plays a role in the development of cardiovascular disease and tumor immunity. Here, we determined the minimum inhibitory concentration (MIC) of antibiotics against Escherichia coli under gradient concentrations of TMAO and performed a bacterial killing analysis. Overall, TMAO (in the range of 10 ~ 100 mM) increased the MIC of quinolones, aminoglycosides, and β-lactams in a concentration-dependent manner, and increased the lethal dose of antibiotics against E. coli. It implies that TMAO is a potential risk for failure of anti-infective therapy, and presents a case for the relationship between intestinal flora-derived metabolites and antibiotic resistance. Further data demonstrated that the inhibition of antibiotic efficacy by TMAO is independent of the downstream metabolic processes of TMAO and the typical bacterial resistance mechanisms (mar motif and efflux pump). Interestingly, TMAO protects E. coli from high-protein denaturant (urea) stress and improves the viability of bacteria following treatment with two disinfectants (ethanol and hydrogen peroxide) that mediate protein denaturation by chemical action or oxidation. Since antibiotics can induce protein inactivation directly or indirectly, our work suggests that disruption of protein homeostasis may be a common pathway for different stress-mediated bacterial growth inhibition/cell death. In addition, we further discuss this possibility, which provides a different perspective to address the global public health problem of antibiotic resistance.
Applying Sonification to Sketching in the Air With Mobile AR Devices

With more and more mobile devices (such as smart phones and tablets) supporting augmented reality (AR), using these devices to sketch in mid-air has become a popular application direction. However, due to the small display size of these devices, the user's field of view is limited and cannot see the context of graphics, which leads to the drawn graphics deviating from their expectations. In this article, we applied sonification technology to mid-air sketching with mobile AR device, and proposed a new method to address this problem. In our first experiment, we verified the feasibility of our method. Our experimental results showed that sonification can effectively reduce the deviation caused by a narrow field of view. In our second experiment, we further explored the application ability of this method in a wider range of sketching. Our experimental results showed that sonification can improve the aspect ratio of the drawn graphics. In addition, the results of the NASA-TLX questionnaire showed that the participants' mental demand and effort decreased significantly, and their subjective performance increased significantly. We proposed a new method, which can effectively improve the accuracy of mid-air sketching with a mobile AR device.
Thirsty Country: State, Water, and the “War on Drought” in Chile in the 1960s

Objective/Context: This paper studies the role of the Chilean state during the great drought of 1967-1969 as a mediator between human beings and nature. Institutional adaptations and the effort to improve the infrastructure were elements of continuity with respect to previous droughts, but there were novelties as well, such as attempts to pursue weather modification and the artificial melting of glaciers. The support of technologies and scientists operating from peripheral state institutions was essential for these purposes. All the above took place in the context of the Cold War when the predominant environmental imaginaries made human intervention look favorable and necessary for the modernization of countries. Methodology: Diverse primary sources were used, such as ministerial documents, decrees, bulletins, and reports of different state institutions that allowed understanding the logic of state management during the water crisis. Similarly, research in national and international press helped identify how imaginaries about the environment were expressed and disseminated publicly, which tended to validate novel efforts to control nature. Originality: This is an original study for Latin America, which addresses the early appearance of science and technology in the efforts of what today would be known as geoengineering: mainly through the observation of new actors, which expanded the traditional forms of mediation between humans and nature, led by the state, concerning climate crises. Conclusions: In the 1960s, optimism grew for the human capacity to control and manipulate water resources by appealing to ways other than those previously known, associated with infrastructure development. Expert knowledge was placed at the service of peripheral institutions of the state to promote these changes with lasting consequences. The human desire to control nature at all costs was validated, which helps explain the temporal projection of experiments with artificial rain and glacier control to the present day in Chile

El extracto de Mentha piperita incrementa la supervivencia del camarón Litopenaeus vannamei infectado experimentalmente con Vibrio spp

Las enfermedades bacterianas más importantes en el cultivo de Litopenaeus vannamei son las vibriosis originadas por Vibrio spp, las que son usualmente tratadas con oxitetraciclina (OTH). Los extractos vegetales son una alternativa para su tratamiento. El estudio tuvo como objetivo determinar el efecto de tres extractos de menta (Mentha piperita) en la supervivencia de camarones infectados experimentalmente con Vibrio spp. Se prepararon tres extractos: etanólico en baño maría (EBM), en aceite de oliva en baño maría (ABM) y macerado en aceite de oliva (MA). Se aislaron 20 cepas de Vibrio spp de camarones de cultivo y se realizó un ensayo in vitro de su sensibilidad a tres dosis (10, 15 y 20 µl) de los extractos. Se realizó un ensayo in vivo por 16 días con 180 camarones de 4.5 g infectados por inmersión con 105 UFC/ml de las cepas de Vibrio spp en tres tratamientos: 1) alimento con EBM, 2) con 3‰ de OTH y 3) sin ningún aditivo. Se evaluó la supervivencia, crecimiento y carga de Vibrio spp en el hepatopáncreas. Se determinó que in vitro, los tres tipos de extractos pudieron inhibir a Vibrio spp, siendo 20 µl de EBM el de mayor inhibición, aunque su poder fue menor al de OTH (diámetro del halo de inhibición equivalente a 58.2% del de OTH). En el ensayo in vivo, el EBM mostró ser tan eficiente como la OTH en incrementar la supervivencia y el crecimiento en peso, así como en reducir la carga de Vibrio spp en hepatopáncreas de los camarones infectados (p<0.05). Se concluyó que el EBM es una alternativa tan eficiente como la oxitetraciclina para incrementar su supervivencia de camarones infectados con Vibrio spp.
