No full textStatistical Reasoning of Impact of Motivation on Students’ Achievement in Foreign Language Learning
No full textAbstractThis research focuses on statistical reasoning in motivation issues in learning a foreign language. The opinions of university students studying at different departments and taking a foreign language course have been investigated through 43 statements related to motivation issues in order to find out their opinions on motivation sources in general, classroom motivation sources and motivation problems that arise or they encounter during their foreign language studies. The responses of participants through all the statements were in very close line with each other, without revealing any significant difference. The relation between the participants achievement level in foreign language courses and motivation revealed contradiction as the respondents claim lack of motivation but have a achievement level over the minimum pass level. This result reveals that in terms of statistical reasoning there is a contradiction between negative motivation and positive achievement

Determination of the Opinions of Students on Tourism Impact Using Mobile Applications
No full textAbstractSince smart phones has become popular, we have been introduced to a huge volume of mobile applications. Every day, we are able to find a new mobile application for different purposes. With these applications, we can edit our photos or contact people on social networks. The main aim of this study is to determine the students’ opinions on Tourism impact using Mobile Applications. In line with this aim, the authors developed a 5-point Likert-type scale consisting of 20 positive statements. The scale was administered to 352 distance learning students during the 2014-2015 spring terms at Near East University. Data were analyzed with IBM SPSS 22. The results showed that students prefer Trip Advisor application to find historical places and they select places to visit after they read user comments. Students also revealed that booking.com are more reliable than other applications. Besides, students prefer to download maps applications and they use GPS when they travel the cities

Today ginger is part of the folk medicine as well as in modern medicine. It is used for the treatment of nausea and vomiting in pregnancy and for prevention of travel and sea sickness. Many countries have approved ginger as a nonprescription drug for the prevention of motion sickness. It is also recognized with its anti-inflammatory effect in treatment of rheumatoid arthritis and osteoarthritis, being on par with many steroidal preparations. The essential oil of Rhizoma Zingiberis (Ginger) include o-zingiberene, ar-curcumene, o-bisabolene, neral, geranial, (E)-a-farnesene and zingiberol. Pungent compound (gingerols and shogaols), diarylheptanoids (gingerenones A and B), vitamins and “050 starch are also present. Fresh ginger root contains gingerols, shogaols, 6- dehydrogingerdione, and galanolactone as the major constituents. 6-gingerol is the main pungent component of dried ginger. 6-gingerol can convert to 6-shogaols due to dehydration of 6-gingerols. Fresh ginger is used as antiemetic, antitussive, expectorant, and for inducing perspiration and dispel cold, whereas dried ginger is used for stomachache, vomiting, and diarrhoca accompanied by cold extremities and low pulse, resolve phlegm retention, for cough and dyspnea with copious frothy expectoration and for abnormal uterine bleeding. In vitro studies have shown that fresh ginger extract inhibits both cyclooxygenase and lipoxygenase. Inhibition of arachidonic acid metabolism results with platelet aggregation and inhibition of prostaglandin and leukotriene production. 6-gingerol, 10- dehydrogingerdione and 10-gingerdione are the main ingredients responsible from these effects. According in vitro studies, these components inhibit prostaglandin synthesis more potentiy than indomethacin. The chemical structures of gingerols shows partial similarities with prostaglandins. Gingerols have been found to be potent inhibitors of prostaglandin biosynthesis. 6-gingerol reduces nausea and vomiting by increasing motility. Galanolacton, similar with ondansetron, has an anti- emetic effect via serotonin (5HT-3) receptors located in ileum. Antiserotonergic activity of ginger including 6-, 8- ve 10-gingerols has also been shown by in vitro studies. Dried ginger is shown to be useful in rheumatoid arthritis. More than 7596 of arthritis patients who consumed ginger rhizome powder experienced analgesic effects and .reduction in joint swelling. Gingerols have been reported to be hypoglycemic in diabetic rats. Ginger can interact with antacids, H2 antagonists and proton pump inhibitors by its potential in increasing stomach pH. The high dosage of ginger may cause central nervous system (CNS) depression and theoretically increases the effect of barbiturates, benzodiazepines and CNS depressants. Ginger may have a dose-dependent inotropic activity and theoretically may interact with positive inotropic agents and beta-blockers. In diabetic rats serum glucose levels are significantly lowered due to the hypoglycemic effect of ginger, which may Corresponding Author: AYŞE SAİDE ŞAHİN, 1NECMETTİN ERBAKAN ÜNİVERSİTESİ MERAM TIP FAKÜLTESİ TIBBİ FARMAKOLOJİ AD. 2NECMETTİN ERBAKAN ÜNİVERSİTESİ MERAM TIP FAKÜLTESİ ÜROLOJİ AD. 3KTO KARATAY ÜNİVERSİTESİ TIP FAKÜLTESİ TIBBİ FARMAKOLOJİ AD
‐Aminobenzene Sulfonic Acid) Film Modified Glassy Carbon Electrode
No full textAcyclovir is an antiviral effective drug active compound. A glassy carbon electrode (GCE) was modified with an electropolymerized film of p-aminobenzene sulfonic acid (p-ABSA) in phosphate buffer solution (PBS). The polymer film-modified electrode was used to electrochemically detect acyclovir. Polymer film showed excellent electrocatalytic activity for the oxidation of acyclovir. The anodic peak potential value of the acyclovir at the poly(p-ABSA) modified glassy carbon electrode was 950mV obtained by DPV. A linear calibration curve for DPV analysis was constructed in the acyclovir concentration range 2x10(-7)-9x10(-6)molL(-1). Limit of detection (LOD) and limit of quantification (LOQ) were obtained as 5.57x10(-8) and 1.85x10(-7)molL(-1) respectively. The proposed method exhibits good recovery and reproducibility
Impacts of aerosol particles on the microphysical and radiative properties of stratocumulus clouds over the southeast Pacific Ocean
No full textThe southeast Pacific Ocean is covered by the world's largest stratocumulus cloud layer, which has a strong impact on ocean temperatures and climate in the region. The effect of anthropogenic sources of aerosol particles on the stratocumulus deck was investigated during the VOCALS field experiment. Aerosol measurements below and above cloud were made with a ultra-high sensitivity aerosol spectrometer and analytical electron microscopy. In addition to more standard in-cloud measurements, droplets were collected and evaporated using a counterflow virtual impactor (CVI), and the non-volatile residual particles were analyzed. Many flights focused on the gradient in cloud properties on an E-W track along 20° S from near the Chilean coast to remote areas offshore. Mean statistics, including their significance, from eight flights and many individual legs were compiled. Consistent with a continental source of cloud condensation nuclei, below-cloud accumulation-mode aerosol and droplet number concentration generally decreased from near shore to offshore. Single particle analysis was used to reveal types and sources of the enhanced particle number that influence droplet concentration. While a variety of particle types were found throughout the region, the dominant particles near shore were partially neutralized sulfates. Modeling and chemical analysis indicated that the predominant source of these particles in the marine boundary layer along 20° S was anthropogenic pollution from central Chilean sources, with copper smelters a relatively small contribution. Cloud droplets were smaller in regions of enhanced particles near shore. However, physically thinner clouds, and not just higher droplet number concentrations from pollution, both contributed to the smaller droplets. Satellite measurements were used to show that cloud albedo was highest 500–1000 km offshore, and actually slightly lower closer to shore due to the generally thinner clouds and lower liquid water paths there. Thus, larger scale forcings that impact cloud macrophysical properties, as well as enhanced aerosol particles, are important in determining cloud droplet size and cloud albedo. Differences in the size distribution of droplet residual particles and ambient aerosol particles were observed. By progressively excluding small droplets from the CVI sample, we were able to show that the larger drops, some of which may initiate drizzle, contain the largest aerosol particles. Geometric mean diameters of droplet residual particles were larger than those of the below-cloud and above cloud distributions. However, a wide range of particle sizes can act as droplet nuclei in these stratocumulus clouds. A detailed LES microphysical model was used to show that this can occur without invoking differences in chemical composition of cloud-nucleating particles
