        Cross-sectional study: prevalence of subclinical ketosis in dairy cattle at Chungnam province

        Faruk,,Md.,Shohel,Al,Park,,Byeongsu,Jin,,Sujeong,Ha,,Seungmin,Cho,,Yong-il The Korean Society of Veterinary Service 2018 韓國家畜衛生學會誌 Vol.41 No.2

        This study was conducted to demonstrate the prevalence of subclinical ketosis in dairy cattle based on days in milk and herd level. Four to five blood samples were collected in five different lactation periods and analyzed for ${\beta}$-hydroxybutyrate using a Portable Ketone Test Kit. Subclinical ketosis was observed in 12 herds at prevalence of 6.3~57.1% depending on herd level, with four herds showing more than 40% subclinical ketosis prevalence. The distribution of subclinical ketosis in the early lactation period, high yield lactation period, mid lactation period, late lactation period and dry period was 9.5%, 27.5%, 36.8%, 27.9% and 12.5%, respectively. Clinical ketosis was only observed during early lactation (9.5%) and mid lactation (2%) period.

        Cultural intelligence as a predictor of individuals' adaptive performance: A study in a multicultural environment

        Faruk,Şahin,Sait,Gürbüz 한국외국어대학교 국제지역연구센터 2014 International Area Studies Review Vol.17 No.4

        As the work environment is changing rapidly, organizations need more adaptable employees who can work creatively, learn new skills and adapt to diverse social contexts and novel environments. Individual differences such as prior experience and self-efficacy have been extensively examined as predictors of adaptive performance. In contrast, the role of cultural intelligence in promoting adaptive performance has been overlooked. The primary goal of this study was to examine cultural intelligence that may account for adaptive performance beyond prior experience and self-efficacy. Moreover, we examined the moderating role of self-efficacy in terms of the relationship between cultural intelligence and adaptive performance. We tested our hypothesis with multisource data in a sample of 132 military personnel assigned in a multinational military organization. Hierarchical regression analysis demonstrated that cultural intelligence, together with self-efficacy and prior experience, was important predictors of adaptive performance. Specifically, cultural intelligence explained additional variance in adaptive performance over and above that of prior experience and self-efficacy. These findings suggested the importance of cultural intelligence as a critical predictor of adaptive performance in multicultural contexts.

        What is the changing frequency of diamond burs?

        Faruk,Emir,Simel,Ayyildiz,Cem,Sahin 대한치과보철학회 2018 The Journal of Advanced Prosthodontics Vol.10 No.2

        PURPOSE. The purpose of this study was to determine the changing frequency of a diamond bur after multiple usages on 3 different surfaces. MATERIALS AND METHODS. Human premolar teeth (N = 26), disc shaped direct metal laser sintered CoCr (N = 3) and zirconia specimens (N = 3) were used in this study. Groups named basically as Group T for teeth, Group M for CoCr, and Group Z for zirconia. Round tapered black-band diamond bur was used. The specimens were randomly divided into three groups and placed with a special assembly onto the surveyor. 1, 5, and 10 preparation protocols were performed to the first, second, and third sub-groups, respectively. The subgroups were named according to preparation numbers (1, 5, 10). The mentioned bur of each group was then used at another horizontal preparation on a new tooth sample. The same procedure was used for CoCr and zirconia disc specimens. All of the bur surfaces were evaluated using roughness analysis. Then, horizontal tooth preparation surfaces were examined under both stereomicroscope and SEM. The depth maps of tooth surfaces were also obtained from digital stereomicroscopic images. The results were statistically analyzed using One-Way ANOVA, and the Tukey HSD post-hoc tests (α=.05). RESULTS. All of the groups were significantly different from the control group (P<.001). There was no significant difference between groups Z5 and Z10 (P=.928). Significant differences were found among groups T5, M5, and Z5 (P<.001). CONCLUSION. Diamond burs wear after multiple use and they should be changed after 5 teeth preparations at most. A diamond bur should not be used for teeth preparation after try-in procedures of metal or zirconia substructures.

        Effect of Tricho-compost against Seedling Blight Disease of Wheat Caused by Sclerotium rolfsii

        Faruk,,M.,Iqbal The Korean Society for Microbiology and Biotechnol 2018 한국미생물·생명공학회지 Vol.46 No.4

        The efficacy of formulated Trichoderma harzianum-based Tricho-compost, seed treatment with Tricho-inocula, and chemical fungicide Provax 200 WP against foot and root rot diseases of wheat caused by Sclerotium rolfsii was tested in the pot house and in the research field of Plant Pathology Division, Bangladesh Agricultural Research Institute, Gazipur, Bangladesh. Tricho-compost was prepared with a mixed substrate of cow dung, rice bran, and poultry refuse colonized by T. harzianum. Seedling mortality of wheat was significantly reduced by the Tricho-compost, Tricho-inocula, and Provax 200 WP both in the pot house as well as in the field experiments. The yield of wheat was sharply increased over the control due to the T. harzianum formulations and Provax 200 WP. Among the treatments, soil application of Tricho-compost was more efficient in reducing seedling mortality and accelerating plant growth with an increased yield of wheat with S. rolfsii-inoculated pot cultures and field experiments.

      • Long-term stability of dentoalveolar, skeletal, and soft tissue changes after non-extraction treatment with a self-ligating system

        Objective: To evaluate the long-term effects of self-ligating brackets (SLBs) on transverse dimensions of arches and skeletal and soft tissues and to quantitatively evaluate the treatment outcome after non-extraction treatment with SLBs. Methods: The sample consisted of 24 (18 female and six male) subjects, with a mean age of 14.23 ± 2.19 years, who received treatment with the Damon<SUP>®</SUP>3 appliances. Complete records including cephalometric radiographs and plaster models were obtained before treatment (T1), immediately after treatment (T2), six months after treatment (T3), and two years (T4) after treatment. Digital study models were generated. Twenty lateral cephalometric, six frontal cephalometric, and eight dental cast measurements were examined. The Peer Assessment Rating index was used to measure the treatment outcome. The Wilcoxon test was applied for statistical analysis of the changes. Results: There were significant increases in all transverse dental cast measurements with active treatment. There was some significant relapse in the long term, particularly in maxillary width (p < 0.05). Statistically significant increases were found in nasal (p < 0.001), maxillary base, upper molar, lower intercanine, and antigonial (p < 0.05) widths in T1-T2. Lower incisors were proclined and protruded in T1-T2. Conclusions: SLBs correct crowding by mechanisms involving incisor proclination and protrusion and expansion of the dental arches, without induction of clinically significant changes in hard and soft tissues of the face.

        Enhancement of Downward-Facing Saturated Boiling Heat Transfer by the Cold Spray Technique

        Faruk,A.,Sohag,Faith,R.,Beck,Lokanath,Mohanta,Fan-Bill,Cheung,Albert,E.,Segall,Timothy,J.,Eden,John,K.,Potter 한국원자력학회 2017 Nuclear Engineering and Technology Vol.49 No.1

        In-vessel retention by passive external reactor vessel cooling under severe accident conditionsis a viable approach for retention of radioactive core melt within the reactor vessel. In this study, a new and versatile coating technique known as “cold spray” that can readilybe applied to operating and advanced reactors was developed to form a microporouscoating on the outer surface of a simulated reactor lower head. Quenching experimentswere performed under simulated in-vessel retention by passive external reactor vesselcooling conditions using test vessels with and without cold spray coatings. Quantitativemeasurements show that for all angular locations on the vessel outer surface, the localcritical heat flux (CHF) values for the coated vessel were consistently higher than thecorresponding CHF values for the bare vessel. However, it was also observed for bothcoated and uncoated surfaces that the local rate of boiling and local CHF limit varyappreciably along the outer surface of the test vessel. Nonetheless, results of this intriguingstudy clearly show that the use of cold spray coatings could enhance the local CHF limit fordownward-facing boiling by > 88%.

        Asymmetrical Dimethylarginine Levels in Hepatitis B Virus-Positive Patients

        Faruk,Karakecili,Aytekin,Cikman,Merve,Aydin,Baris,Gulhan 대한진단검사의학회 2018 Annals of Laboratory Medicine Vol.38 No.5

        Background: High asymmetrical dimethylarginine (ADMA) levels have been associated with endothelial dysfunction and contribute to the development of several diseases. However, data on the relationship between hepatitis B virus (HBV) and ADMA are limited. The aim of our study was to explore the relationship between ADMA and HBV by comparing the ADMA levels in patients with chronic active hepatitis B (CHB), inactive HBV carriers (carriers), and healthy volunteers (controls). Methods: The participants were divided into three groups: 90 patients with CHB, 90 HBV carriers, and 90 controls. Serum ADMA levels were quantified using an ELISA kit (Cusabio, Wuhan, China). The data were analyzed using an ANOVA or the Kruskal-Wallis test as appropriate, with P<0.05 considered significant. Results: Serum ADMA levels were significantly higher in patients with CHB (228.35±91.10 ng/mL) than in HBV carriers (207.80±75.80 ng/mL) and controls (207.61±89.10 ng/mL) (P=0.049). The clinical scores of the patients were positively correlated with ADMA levels. Conclusions: The elevated serum ADMA levels in patients with CHB confirm that HBV plays a role in vasculitis. Further investigation of the mechanisms contributing to the high levels of ADMA in CHB may contribute toward development of new treatment modalities

        Dynamic response of curved Timoshenko beams resting on viscoelastic foundation

        Faruk,Fırat,Calim 국제구조공학회 2016 Structural Engineering and Mechanics, An Int'l Jou Vol.59 No.4

        Curved beams' dynamic behavior on viscoelastic foundation is the subject of the current paper. By rewritten the Timoshenko beams theory formulation for the curved and twisted spatial rods, governing equations are obtained for the circular beams on viscoelastic foundation. Using the complementary functions method (CFM), in Laplace domain, an ordinary differential equation is solved and then those results are transformed to real space by Durbin's algorithm. Verification of the proposed method is illustrated by solving an example by variating foundation parameters.
