This study examined whether the average usability score for a series of tasks was the same as the usability score for the product if usability was measured only after all the tasks had been completed. Fifty participants completed a set of tasks for five websites and fourteen mock voting ballots. Subjective usability assessment was made with the System Usability Scale (SUS). Participants complet...

آگاهی از میزان تاج‌پوشش درختان در مناطق شهری به‌علت تأثیرات آن کاهش آلودگی‌‌های هوا، آلودگی صوتی، جلوگیری باد، ذخیرة نزولات آسمانی، و کنترل رواناب‌های بسیار ضروری است. ازآن‌جا‌که استخراج با روش‌های دستی وقت‌گیر پرهزینه است، تکنیک‌های سنجش دور می‌توانند ابزار مناسبی برای تأمین این داده‌ها باشند. طبقه‌بندی شیء‌پایه، انتخاب پارامترهای بهینة قطعه‌بندی، به‌ویژه پارامتر مقیاس، اهمیت بسیاری دارد معمول...

OBJECTIVES Report the incidence and structure of testicular appendices (TAs) in patients with cryptorchidism, comparing their incidence with epididymal anomalies (EA) and patency of the vaginal process (PVP) and analyzes the structure of TAs. MATERIAL AND METHODS We studied 72 testes of patients with cryptorchidism (average of 6 years), and 8 testes from patients with hydroceles (average of 9...

OBJECTIVE The present study aimed to investigate the effect of the interaction between the number of traumas experienced and alexithymia, on posttraumatic stress disorder (PTSD) symptoms. METHODS The sample comprised 199 North Korean refugees. Participants completed the Trauma Exposure Check List for North Korean Refugees, Impact of Event Scale-Revised (IES-R), Toronto Alexithymia Scale-20 (T...

The present study aimed to study the changes of neurotrophin-3 (NT-3) expression of intrafusal muscle fibers in rat soleus muscles under simulated weightlessness. The tail-suspension (SUS) rat model was used to simulate weightlessness. Forty mature female Sprague-Dawley rats were randomly assigned to ambulatory control (CON), 3-day SUS, 7-day SUS, 14-day SUS and 21-day SUS groups. Immunohistoch...

Graduate teaching assistants (TAs) are increasingly responsible for instruction in undergraduate science, technology, engineering, and mathematics (STEM) courses. Various professional development (PD) programs have been developed and implemented to prepare TAs for this role, but data about effectiveness are lacking and are derived almost exclusively from self-reported surveys. In this study, we...

Telomeres are generally considered heterochromatic. On the basis of DNA composition, the telomeric region of Drosophila melanogaster contains two distinct subdomains: a subtelomeric region of repetitive DNA, termed TAS, and a terminal array of retrotransposons, which perform the elongation function instead of telomerase. We have identified several P-element insertions into this retrotransposon ...

Bifidobacteria are colonizers of the human gut, where they are interacting with their host as well as with other members of the intestinal microbiota. Teichoic acids (TAs) have previously been shown to play an important role in modulating microbe-host interactions in the human gut. However, so far, there is a paucity of information regarding the presence of TAs in the cell envelope of bifidobac...

TAS loci in plant genomes encode transacting small interfering RNAs (ta-siRNAs) that regulate expression of a number of genes. The function of TAS3 precursor in Arabidopsis thaliana is controlled by two miR390 target sites flanking two ta-siARF sequences targeting mRNAs of ARF transcription factors. Cleavage of the 3'-miR390-site initiates ta-siRNAs biogenesis. Here we describe the new method f...

Introduction: Mass lesions are seen in the uterus in 15 to 20% of women in the reproductive age group. Transabdominal(TAS) ultrasound(USG) is the screening imaging modality of choice. Definitive characterisation of the site, location, endometrial distorsion and number of lesions are important to decide on the treatment Aims and objectives: We compared the sensitivity and specificity of Magnetic...
