An Investigation on Production of Blended Cement with Natural Building Stone Waste Resistant to Sulphate Effects

In this study, the cements produced by the additive materials from Isparta city, Turkeyand its region which gives puzzolanic activity are compared with normal Portland cement. Inthis comparison sulphate resistance and other cement properties are examined.The natural additives which undergone various procedures are blended with clinker andgypsum under different proportions, which are main cement compounds. Prepared mortarspecimens cured in the water for 28 days and then they were exposed to three differentproportions of sodium sulphate solution for 125 days. Afterwards performances of cementsare determined with compressive strength. Also the prepared specimens for during 3 monthsperiod and there are cured under moist atmosphere volume expansion are measured andcontinuously monitored.The results show that, diatomite blended cement having more porous structure thanandesite powder were more affected by sulphate attack. As in the normal standard tests, byadding 10 % of these materials gave similar strength values with 42.5 Portland cement, atlater periods of time

Investigation of Leisure Time Attitude of University Students According to Some Parameters (Example of Northern Cyprus)

The attitude of leisure can be defined as all the emotions, thoughts, attitudes and behaviors shown for the leisure concept. The aim of this study is to examine the leisure attitudes of the students of the Cyprus University according to various parameters such as gender, age, class, faculty and whether to do recreational sports. A total of 265 students participated in the study. Leisure Attitude Scale was used to evaluate student’s leisure attitudes. Independent sample t test was used for analyzing gender and recreational sports variables, and the one-way ANOVA test was used for analysis of age, class and faculty variables. According to the results obtained, there was a significant difference in the cognitive, affective and behavioral dimensions of the three sub-dimensions of the scale for the variable of doing recreational sports. In addition, differentiation was observed in the cognitive sub-dimension for the age variable and the behavioral sub-dimension for the class variable

Impact of Virologic Breakthrough and HBIG Regimen on Hepatitis B Recurrence After Liver Transplantation

The availability of hepatitis B immune globulin (HBIG) and several oral antiviral therapies has reduced but not eliminated hepatitis B virus (HBV) recurrence. We aimed to determine the rate of HBV recurrence after orthotopic liver transplantation (OLT) in relation to virologic breakthrough pre-OLT and HBIG regimens post-OLT. Data from the NIH HBV-OLT database were analyzed. A total of 183 patients transplanted between 2001 and 2007 followed for a median of 42 months (range 1–81) post-OLT were studied. At transplant, 29% were hepatitis B e antigen (HBeAg) (+), 38.5% had HBV DNA > 5 log 10 copies/mL, 74% were receiving antiviral therapy. Twenty-five patients experienced virologic breakthrough before OLT. Post-OLT, 26%, 22%, 40% and 12% of patients received intravenous (IV) high-dose, IV low-dose, intramuscular low-dose and a finite duration of HBIG, respectively as maintenance prophylaxis. All but two patients also received antiviral therapy. Cumulative rates of HBV recurrence at 1 and 5 years were 3% and 9%, respectively. Multivariate analysis showed that listing HBeAg status and HBV DNA level at OLT were the only factors associated with HBV recurrence. In conclusion, low rates of HBV recurrence can be accomplished with all the HBIG regimens used when combined with antiviral therapy including patients with breakthrough pre-OLT as long as rescue therapy is administered pre- and post-OLT.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/79358/1/j.1600-6143.2010.03046.x.pd

Objective: Turner syndrome (TS) is a chromosomal disorder caused by complete or partial X chromosome monosomy that manifests various clinical features depending on the karyotype and on the genetic background of affected girls. This study aimed to systematically investigate the key clinical features of TS in relationship to karyotype in a large pediatric Turkish patient population.Methods: Our retrospective study included 842 karyotype-proven TS patients aged 0-18 years who were evaluated in 35 different centers in Turkey in the years 2013-2014.Results: The most common karyotype was 45,X (50.7%), followed by 45,X/46,XX (10.8%), 46,X,i(Xq) (10.1%) and 45,X/46,X,i(Xq) (9.5%). Mean age at diagnosis was 10.2±4.4 years. The most common presenting complaints were short stature and delayed puberty. Among patients diagnosed before age one year, the ratio of karyotype 45,X was significantly higher than that of other karyotype groups. Cardiac defects (bicuspid aortic valve, coarctation of the aorta and aortic stenosis) were the most common congenital anomalies, occurring in 25% of the TS cases. This was followed by urinary system anomalies (horseshoe kidney, double collector duct system and renal rotation) detected in 16.3%. Hashimoto's thyroiditis was found in 11.1% of patients, gastrointestinal abnormalities in 8.9%, ear nose and throat problems in 22.6%, dermatologic problems in 21.8% and osteoporosis in 15.3%. Learning difficulties and/or psychosocial problems were encountered in 39.1%. Insulin resistance and impaired fasting glucose were detected in 3.4% and 2.2%, respectively. Dyslipidemia prevalence was 11.4%.Conclusion: This comprehensive study systematically evaluated the largest group of karyotype-proven TS girls to date. The karyotype distribution, congenital anomaly and comorbidity profile closely parallel that from other countries and support the need for close medical surveillance of these complex patients throughout their lifespa

Two Cases of Primary Hepatic Neuroendocrine Tumors and a Review of the Current Literature

Neuroendocrine tumors comprise approximately 1-2% of all gastrointestinal tumors, and while the liver is the most common site for metastasis of these tumors, primary hepatic neuroendocrine tumors are very rare entities. Since first being reported in 1958, there have been less than 150 cases reported in the literature. Because of the infrequent occurrence of these tumors, the pool of data available for analysis regarding these tumors is small. As such, the medical community must rely on the publication of case report data to further enlarge this data pool, with the hopes of eventually having enough data to draw meaningful, statistically significant conclusions with regard to diagnosis and management of these rare tumors. We have encountered two patients at our institution within the last year with primary hepatic neuroendocrine tumors. We present their cases in this manuscript in an effort to contribute to the available data on the disease. We also provide a concise review of the literature available to date regarding primary hepatic neuroendocrine tumors

Effect of pentoxifylline on healing of segmental bone defects and angiogenesis

Objective: The aim of this study was to determine the effect of pentoxifylline (PTX) on angiogenesis and the healing of a critical-sized segmental defect of the radius diaphysis in a rat model, using radiological and histological grading systems. Methods: The study included 24 female Sprague-Dawley rats (weight: 300 +/- 20 g) divided into 4 groups. A critical-sized segmental defect was created in the radius diaphysis in all rats. In Group 1, morcellized iliac crest autografts were used to fill the segmental bone defect. In Group 2, segmental bone defects were filled using morcellized iliac crest autografts, and 25 mg/kg/day PTX was applied intraperitoneally. In Group 3, the segmental bone defects were not filled, and in Group 4 the segmental bone defects were left unfilled, and an intraperitoneal (IP) dose of 25 mg/kg/day PTX was applied. Rats were sacrificed at postoperative Week 8, and defects were evaluated using radiographic, histological and immunohistochemical methods. Results: There were significant differences between Group 1 and 2 according to radiological evaluation (p = 0.003) and quality of union at the defect site (p = 0.01). Union quality was higher in Group 4 than Group 3 (p = 0.01). Cluster of differentiation 31 (CD31) and vascular endothelial growth factor (VEGF) levels were higher in Group 2 than in Groups 3 and 4. Conclusion: According to radiological and histological parameters, PTX appears to improve angiogenesis and healing of segmental cortical bone defects of the radius in a rat model

Temporal and clinical distribution of 112 emergency call system use of geriatric patients during novel coronavirus pandemic process

112 emergency call system is crucial for geriatric patients because the safe and secure transport of these patients can decrease mortality and morbidity. The present study was a temporal and clinical evaluation of cases with COVID-19 and non-COVID-19 older than 65 years of age during the pandemic. Of the 10948 cases accepted diagnosed with novel coronavirus between March 11 and May 1, 2020, 51.6% (n=5650) were female, 48.4% (n=5298) were male and the median age was 75.0 (70.0-81.0) years. The patients were compared concerning age, gender, month distribution, symptoms, comorbidity, computed tomography results, hospitalization, and discharge criteria. Concerning symptoms, the findings showed that 50.0% (n=5476) had high fever, 50.3% (n=5504) had cough, 59.5% (n=6509) had shortness of breath. Atypical complaints were found in 21.3% (n=2337) of the patients. Concerning comorbidity, 10.3% (n=1126) had hypertension, 5.8% (n=633) had diabetes mellitus, 7.2% (n=784) had chronic obstructive pulmonary disease and 0.9% (n=95) had cerebrovascular disease. The findings showed that 26.0% of the cases were hospitalized, while 74.0% (n=8098) were discharged. In 112 call center calls, being more careful and alert in the anamnesis of the geriatric patient group defined as important concerning the atypical course and potential risk factors and in the use of protective equipment is important for safe and secure transport of patients and since this will decrease mortality and morbidity.

A human reliability analysis for ship to ship LNG bunkering process under D-S evidence fusion HEART approach

LNG (Liquid Natural Gas) ship to ship bunkering process is quite a new concept for the maritime industry since the usage of LNG has been increasing worldwide. The LNG bunkering process poses a high risk due to human errors, while a minor error may be catastrophic. The expectation of the ship's crew is to carry out operations without any errors. Therefore, human reliability analysis (HRA) is paramount to improving operational safety during the ship to ship LNG bunkering process. In this context, this paper performs a systematic HRA under the D–S (Dempster-Shafer) evidence fusion-based HEART (human error assessment and reduction technique) approach. While the HEART quantifies human error for the tasks being performed, the extended D-S evidence fusion deals with the limitation of APOA (assessing the proportion of effect) calculation since it significantly relies on evaluating a single rater. The finding shows that human reliability for the ship to ship LNG bunkering process is 5.98E-01 and reasonable, but not at the desired level. The paper's outcomes will contribute to the utmost for LNG ship operators, safety inspectors, and ship owners to establish a safe and efficient ship to ship LNG bunkering process and minimise human error-based accidents
