Verification and Validation of Semantic Annotations

In this paper, we propose a framework to perform verification and validation of semantically annotated data. The annotations, extracted from websites, are verified against the schema.org vocabulary and Domain Specifications to ensure the syntactic correctness and completeness of the annotations. The Domain Specifications allow checking the compliance of annotations against corresponding domain-specific constraints. The validation mechanism will detect errors and inconsistencies between the content of the analyzed schema.org annotations and the content of the web pages where the annotations were found.Comment: Accepted for the A.P.

Effect of in-line tandem configuration on performance and scaling of pitching hydrofoils

Simulations are reported on the behavior of two tandem symmetric foils in an in-line configuration undergoing pitching motion. The Reynolds number was varied between 1000 and 4000, whereas the pitching Strouhal number ranged from 0.2 to 0.5 and the amplitude of pitching varied from 4 to 8 deg. The streamwise separation distance between the foils was fixed at one chord length. The performance of the downstream foil was significantly worsened (up to 80% in efficiency) by the tandem effects. The Strouhal number, Reynolds number, and pitching amplitude had substantial impact on the performance of the downstream foil. For the upstream foil, however, the performance improved by up to 147% in efficiency at all ranges of Reynolds number, Strouhal number, and pitching amplitude. The scaling of the individual foil performance metric and the system collective performance metric were investigated for tandem foils. The scaling developed for isolated foils does hold for tandem foils in the in-line configuration with modified empirical coefficients that depend on reduced frequency and Reynolds number in a range of St and Re. However, the leading foil behavior at lower St is more scattered compared to higher St, which suggests more significant wake interactions that influence the scaling and performance of the leading foil. © 2020 by the American Institute of Aeronautics and Astronautics,.T14-Q01This study has received support from Canada First in Research Excellence through the University of Alberta Future Energy Systems Institute, grant number T14-Q01.

Effect of proprioceptive training on balance in patients with chronic neck pain

OBJECTIVES: The aim of this randomized controlled study was to investigate the effect of proprioceptive training on balance in patients with chronic neck pain (CNP). METHODS: Forty patients participating in the study were randomly divided into study and control groups. Both of the groups underwent conventional physical therapy; additionally, the study group was rehabilitated with gaze direction recognition exercise (GDRE) for proprioceptive training. Exercises were performed during 3 weeks with five sessions per week. Pain intensity [visual analog scale (VAS)], neck disability [Neck Disability Index (NDI)], and balance [four step square test (FSST), single leg balance test (SLBT) with eyes opened and closed] assessments were conducted in the patients before and after the treatment and 3 weeks after the last session. RESULTS: No differences were observed between the groups in terms of pre-treatment measurements. There was a statistically significant decrease in VAS scores in both groups compared with pre-treatment conditions (p0.05). CONCLUSION: Proprioceptive training should be included in physiotherapy programs to improve balance; it decreases the disability level in patients with CNP

Effect of the gaze effect of the gaze direction recognition exercise on pain intensity, balance and disability level in chronic neck pain

Objectives: To determine contributions of the gaze direction recognition exercise (GDRE) to improve pain intensity, balance, and disability level among patients with chronic neck pain. Methods: Eligible 40 patients were randomized to physical therapy program (Group I) or physical therapy plus GDRE (Group II) and were scheduled to receive a 3-week treatment, 5 sessions in a week. Pain Intensity was measured by a Visual Analog Scale (VAS). The Neck Disability Index (NDI) was used to determine disability level. To evaluate balance ability, four step square test (FSST) and single leg balance test (SLBT) with eyes opened and closed were used. All measurements were applied before and after a 3-week treatment program. Results: VAS scores of the two groups decreased after the treatment program (p0.05). Conclusions: The results of this study indicate that adding GDRE to the physical therapy program leads to much more improvements in balance ability and in disability level among patients with chronic neck pain. GDRE can have a positive impact on the treatment program

The effect of saline and non-saline soil conditions on yield and nutritional characteristics of some perennial legumes forages [Bazı baklagil yem bitkisi türlerinin verim ve besin özellikleri üzerine tuzlu ve tuzsuz toprak koşullarının etkisi]

Salinity is one of the important environmental stress factors restricting agricultural productivity and sustainability, particularly in arid and semi-arid regions. In the evaluation of saline soils, growing of salt tolerant or resistant plants is recently a widespread implementation. The aim of this study was to compare some yield and nutritional properties of alfalfa (Medicago sativa L.), sainfoin (Onobrychis sativa Lam.) and bird’s foot trefoil (Lotus corniculatus L.) species cultivated in extreme saline-soil (9.80 EC dS m-1) and non-saline soil (0.43 EC dS m-1) conditions. For this purpose, this research was conducted in randomized blocks design with three replications on the Iğdır Plain, located in eastern Turkey, between the years of 2011-2013. Plants were sown under irrigable conditions in 2011, and data were obtained from the examined plants during three years including the year of sowing. In the study, leaf area index (LAI), crude protein (CP), fresh hay and hay yields differed significantly (P<0.01) in terms of species x soil type x year interaction. In respect to plant height, all the paired interactions, but only soil type x year interaction in terms of neutral detergent fiber (NDF) were found statistically significant. According to these results, maximum fresh hay yields and LAI were obtained from alfalfa grown on non-saline soils in the maintenance years (2012-2013), and maximum hay yields were determined again in alfalfa grown on non-saline soils for each of the three years and also on saline soil in 2012. However, minimum fresh hay and hay yields were measured under saline soil conditions in the establishing year for each of the three species. Maximum and minimum CP contents were found in alfalfa and sainfoin grown on saline soil conditions in the establishing year (2011), respectively. Along with changing as per species, plant heights increased in the years following the establishing year, but decreased on saline soil compared to non-saline soil. In respect of NDF content, the highest values were determined under non saline-soils in 2012, and the lowest ones were obtained from saline soil conditions in 2011 and 2013. As conclusion, it was determined that all species can easily grow without too much yield and quality loss in salt-affected areas and can provide enough forage production for livestock feding. © Ankara Üniversitesi Ziraat Fakültesi.Türkiye Bilimsel ve Teknolojik AraÅ?tirma Kurumu, TÃ?BITAK: 110O259This research was supported by the Scientific and Technological Research Council of Turkey with Project No. 110O259.

Dual effects of melatonin on uterine myoelectrical activity of non-pregnant rats

Objective: In this experimental study, we aimed to investigate the role of melatonin on uterine myoelectrical activity of non-pregnant rats. Material and Methods: Forty-six female rats were assigned to six groups: (1) control; (0.2 mL 0.9% NaCl was injected intravenously (IV), n=6); (2) melatonin applied as 0.4 mg/kg/IV (n=8); (3) melatonin applied as 4 mg/kg/IV (n=8); (4) single dose of oxytocin (100 mU/kg) injected IV (n=8); (5) melatonin (0.4 mg/kg) plus oxytocin (100 mU/kg) (n=8); and (6) melatonin (4 mg/kg) plus oxytocin (100 mU/kg) injected IV (n=8). Each rat underwent a laparotomy, and uterine myoelectrical signals were recorded. The mean spectrum, averaged over the spectral content of signals in each group, was compared. Results: Melatonin induced uterine myoelectrical activity in a dose-dependent manner. Treatment of melatonin after oxytocin suppressed the mean power of the signals. Serum melatonin concentrations were significantly higher in melatonin-treated rats. Conclusion: Melatonin itself at two different dose levels was found to be equally effective in stimulating the uterine electrical signals, although oxytocin-induced uterine electrical activity was suppressed by melatonin. These findings merit further investigations on the possible beneficial role of melatonin in the treatment of conditions associated with abnormal uterine activity. © 2014 by the Turkish-German Gynecological Education and Research Foundation

Effect of the gaze direction task on pain intensity, range of moti̇on and isometri̇c muscle endurance in chronic neck pain

Background and aims: The aim of our study is to research the effect of the gaze direction recognition task on pain intensity, range of motion and isometric muscle endurance in subjects with chronic neck pain. Methods: In total 40 subjects (29-54 ages and 32 females, 8 males) volunteered for our study. The participants were randomly divided in two groups (Group 1 and Control Group). Both groups underwent combined physiotherapy program. Both groups received in total 15 sessions of therapy during 3 weeks, 5 days per week. The Group 1 has additionally underwent 15 sessions of Gaze Direction Recognition Tasks. Pain intensity statistically significant differences were recorded in terms of pain intensity, flexion, lateral flexion of both direction, right rotation range of motion, muscle strength and gaze direction recognition task scores between two groups. Pain intensity (Visual Analog Scale), range of motion (universal goniometer), isometric muscle endurance (craniocervical test) and the Gaze direction recognition task assessments were repeated at baseline, after the treatment programme and 3 weeks after the last session. Results: After therapy, improvement was observed in terms of pain intensity, flexion, extension, lateral flexion, left rotation range of motion and isometric muscle strength in both groups (p<0.05). Conclusions: The Gaze Direction Recognition Tasks given additionally to the combined physiotherapy program has increased the efficiency of the treatment
