Çelik, Necati; Çevik, Ugur; Çelik, Ahmet
Mass attenuation coefficients were determined experimentally for Sc, Ni and W for gamma energies of 59.5, 122, 276, 302, 356, 383 and 662 keV for different detector collimator diameters ranging from 2 to 10 mm. The aim was to investigate the quantitative analysis of detector collimator diameter effect on measured mass attenuation coefficients. It was found that measured mass attenuation coefficients decrease systematically with the increasing collimator diameter. The relative difference was found to be up to around 3% in some cases. The observed decrease in mass attenuation coefficients was attributed to the detection of elastic and inelastic scattered photons from the absorber. In elastic scattering process the photons change in direction but not in energy and get counted under the full energy peak if they reach the detector. In inelastic scattering however, both direction and energy of the scattered photons change. It was seen that most of the inelastic scattered photons also get counted by the detection system since they lose an amount of energy lower than the energy resolution of the detector. It is understood from the present results that it is essential to take into account the experimental geometry when reporting mass attenuation coefficients.

Sevim, B.; Bayraktar, A.; Altunişik, A.C.; Adanur, S.; Akköse, M.
This study investigated the water level effects on the dynamic characteristics of a prototype arch dam model using ambient vibration testing were investigated. Achievement of this purpose involved construction of a prototype arch dam-reservoir-foundation model under laboratory. The dam body was constructed with 60 cm height. Ambient vibration tests on the arch dam estimated its natural frequencies, mode shapes and damping ratios for different water levels. In the ambient vibration tests, ambient excitations are provided from small impact effects and the responses of the arch dam are measured. It can be stated from the study that natural frequencies are not overly changed among 0-30 cm water levels; however they are increased for higher water levels. The difference between the first natural frequencies of the arch dam obtained from empty reservoir (H = 0 cm) and full reservoir (H = 60 cm) is about 20-25%.

Akpinar, Adem; Kömürcü, Murat Ihsan
This study aims to assess and characterize wave energy resource along the southeastern coasts of the Black Sea. For this purpose, wave energy potential was investigated at a total of 7 study points in this area. The potential for energy generation was assessed based on six-hourly data from a third generation wave model (SWAN) covering the period 1995-2009. The results were validated with buoy measurements and wave energy and power was calculated with the numerical hindcast data. For characterization of wave energy potential, average annual and seasonal variations of the wave power in this area was firstly investigated. Second, wave energy development indexes and the probabilities of exceedance of wave power at the study points were determined. Third, wave energy resource in different ranges of significant wave heights and zero-crossing periods were characterized. Finally, It was found that annual wave energy of all points except Sinop point, whose annual wave energy is 10 MWh/m, is approximately 6 MWh/m and the bulk of annual wave energy occurs for significant wave heights between 0.5 and 2 m and periods between 2 and 5 s.

Objectives: This study aims to assess the frequency and factors relevant to metabolic syndrome in workers employed in the collection and disposal of solid waste sector. Materials and Methods: This cross-sectional study was conducted in the major solid waste collecting and disposal company named ISTAC AS (Istanbul Environmental Protection and Waste Processing Corporation) in Istanbul, Turkey. All 715 male employees of the company were included in the study without sampling. The study was completed with 619 subjects. Since it was a small group, female workers were not taken into ac-count in the study. Metabolic syndrome frequency was investigated according to the NCEP-ATP III criteria including the levels of systolic and diastolic blood pressure, waist perimeter, HDL, triglyceride, fasting blood glucose values. Results: Metabolic syndrome was present in 40.9% of participating employees. Metabolic syndrome was more common in those working in the excavation field (54.0%), such as caterpillar operators (56.5%), and less common in employees working in administrative offices, such as office staff or managers, who were under 35 years old and who had been working for less than 10 years (p < 0.05). Employees working in work stations other than administrative offices had a 2.60 times higher risk compared to those working in administrative offices. Conclusions: Metabolic syndrome may be related to work sta-tion, job, age and period worked by the subjects.

Cilingir, Dilek; Gursoy, Ayla Akkas; Colak, Ayse
Aim: Job dissatisfaction and burnout have a negative effect on health care providers, especially nurses. This often results in a shortage of qualified personnel as well as a decrease in the quality and level of care provided to patients. This study carried out to describe the level of burnout and job satisfaction among surgical nurses and to compare them to nurses working in other wards in terms of these aspects. Methods: The study was designed as a cross-sectional and descriptive survey. The sample of the research consisted of 330 nurses working in a tertiary hospital in the northeastern part of Turkey. A questionnaire form, Minnesota Job Satisfaction Questionnaire and Maslach Burnout Inventory were used in order to collect the data. The student t test in independent variables, ANOVA, and Pearson's Correlation Coefficient were used in order to analyze the data. Results: Study results indicated that surgical nurses experienced emotional exhaustion more than pediatric nurses. They had higher levels of depersonalization than the policlinic and gynecological nurses. It was also found that nurses working in operating rooms and urology units experienced more emotional exhaustion than other surgical nurses. Conclusion: The study results showed that the state of emotional exhaustion and depersonalization of the surgical nurses was higher than the means of nurses working in other wards and job satisfaction and personal accomplisment were similar.

Background: The aim of the current study is to compare the results after partial and complete splenic flexure mobilization (SFM). Subjects and Methods: The records of laparoscopic and hand-assisted laparoscopic procedures for primary rectal tumor patients were abstracted from a prospectively designed database. The phrenicocolic and splenocolic ligaments were divided via a four-trocar technique in the partial SFM group, and dissection was continued with the separation of gastrocolic and pancreaticomesocolic attachments via a five-trocar procedure in the complete SFM group. The following data were compared between the groups: Demographics, intra- and postoperative information, and pathological features. Results: In total, 122 cases (77 [63.1%] male, 58.2±13.2 years old) who underwent a partial (n=36, 29.5%) or a complete (n=86, 70.5%) SFM were included. Reservoir creation (48.8% versus 19.4%, P=.003) was more common and conversion (8.1% versus 22.2%, P=.039) was less frequent in the complete SFM group, but there were significantly more T4 tumors in the partial group (16.7% versus 2.3%, P=.008). Demographics, other intra- and postoperative parameters, and pathological features were identical. Conclusions: In our study, complete SFM decreased conversion rates, but this finding may be related to the higher rate of T4 tumors in the partial SFM group. Complete SFM assures an increase in reservoir creation in patients receiving a low anterior resection. Because other parameters are identical, the decision for the level of SFM is better left to the surgeon in cases undergoing a low anterior resection, but complete SFM may be preferred in cases who are candidates for a reservoir formation.

Gezen, Cem; Altuntas, Yunus E.; Kement, Metin; Aksakal, Nihat; Okkabaz, Nuri; Vural, Selahattin; Oncel, Mustafa
Background: This study aims to compare the results of laparoscopic and conventional techniques in patients with low rectal cancers. Subjects and Methods: A retrospective data analysis was initiated in patients underwent laparoscopic or conventional surgery for cancers located in the low (<6 cm) rectum. Patient and tumor-related information, outcomes of operations, and survival were compared between the groups. Results: Among 142 patietns (91 men [64.1%]; mean±standard deviation age, 57.7±14.6 years) who had tumors located <6 cm from the dentate line, 92 (64.8%) were operated on with the laparoscopic technique. Demographics, tumor stage, and localization (2.9±2.0 versus 2.9±2.1 cm from the dentate line in laparoscopic and conventional arms, respectively; P=.968) were similar. However, there were more patients in the laparoscopic group who received neoadjuvant chemoradiation therapy (92.4% versus 80.0%; P=.03), since there were significantly fewer cases with stage I tumors in this group (3.3% versus 14%; P=.33). The conversion rate was 14.1% (n=13). The amount of bleeding and the requirement for transfusion decreased (P<.05 for both), and the possibility of sphincter-saving procedures (66.3% versus 34.0%; P<.001) increased, in the laparoscopy group. Other parameters were identical. In the laparoscopy group, the number of harvested lymph nodes (10.2±5.4 versus 12.4±6.0; P=.025) and the rate of vascular invasion (27.5% versus 47.8%; P=.021) were less, and Kaplan-Meier analysis revealed an improved survival (P=.042), although the follow-up period was significantly shorter in this group (P<.001). Conclusions: Laparoscopic surgery for low rectal cancers may be technically feasible and oncologically safe. Laparoscopy may increase the possibility of sphincter preservation.

AtıfScopus7WoS7OpenAlex7İncele - MakaleAçık Erişim2012Scopus SJRQ1Construction stage analysis of Humber Suspension Bridge
Adanur, Süleyman; Günaydin, Murat; Altunişik, Ahmet Can; Sevim, Bariş
Suspension bridges are widely used as engineering structures to across long spans and give rise to the usage of domains under the bridge. In the finite element analyses of suspension bridges, it is assumed that the structure is built and loaded in a second. However, this type of analysis does not always give the reliable and healthy solutions. Because, construction period of this type of the structures continue along time and loads may be changed during this period. Therefore, construction stages and time dependent material properties should be considered in the analysis to obtain the reliable and healthy results. This paper presents the construction stage analysis of suspension bridges using time dependent material properties. For this purpose, Humber Suspension Bridge built near Kingston upon Hull, England is chosen as an example. Finite element model of the bridge is constituted using SAP2000 program considering project drawings. Geometric nonlinearities are taken into consideration in the analysis using P-Delta large displacement criterion. The time dependent material strength of steel and concrete and geometric variations are included in the analysis. Time dependent material properties are considered as compressive strength, aging, shrinkage and creep for concrete, and relaxation for steel. The structural response of the bridge at different construction stages has been examined. Two different finite element analyses with and without construction stages are carried out and results are compared with each other. As analyses result, variation of the displacement and internal forces such as bending moment, axial forces and shear forces for bridge deck and towers are given with detail. It can be seen from the study that there are some differences between both analyses (with and without construction stages) and the results obtained from the construction stages are bigger. So, it is thought that construction stage analysis using time dependent material properties and geometric nonlinearity should be considered in order to obtain more realistic structural response of suspension bridges.

The purpose of this research is to analyse the multi-item dimensionality of patients' perceived value in hospital service. A total of 564 patients administered to Gulhane Military Medical Academy were surveyed. Sample population was specified through convenience sampling procedure. A face to face survey was conducted by three interviewers in August 2008. Confirmatory Data Analysis was carried out to reach the final data analysis. A scale of overall perceived value in health service was developed, which was composed of three dimensions and represented by 21 items. These dimensions were: Functional value, emotional value, and social value. The results indicated that perceived value was a multidimensional construct that affects the whole process of service purchasing. If the hospitals managers give importance to the sub-dimensions of the patient value inclined to their own hospitals and they regularly examine the situation of these dimensions, they can move one step ahead in achieving patient satisfaction and loyalty.

Eker, Cigdem Saydam; Sipahi, Ferkan; Kaygusuz, Abdullah
Trace elements and rare earth elements (REEs) of Lias-aged cherts in the Gumushane area were studied in order to understand their origin and depositional environment. Twenty three chert samples from five stratigraphic sections were analysed by inductively coupled plasma-mass spectrometry, X-ray diffraction, and mineralogical investigation. Lias cherts in the study area are microcrystalline, cryptocrystalline quartz, and megaquartz depending on mineralogical content. Trace elements of the cherts were compared with PAAS, Co, Y, and Th had stronger depletions in the five sections, whereas V, Ni, Zr, Nb, and Hf had smaller depletions. The distribution of Zr, Hf, and Ta yields Zr/Hf, Zr/Ta and Hf/Ta ratios (25/645, 37/665, and 0.18/3, respectively) that differ from those of chondrites and average upper continental crust, suggesting that these elements are likely non-detrital but are sourced from seawater. Th/U ratios range from 0.04 to 0.45 and are lower than those of the upper continental crust (average: 3.9). Lias-aged cherts have low total REE abundances and stronger depletions in five sections of the PAAS and chondrite-normalised plots. The cherts are characterised by a positive Eu anomaly (average: 4.9) and LREE-enrichment (LaN/YbN=average: 3.5). In addition, about one-half of the cherts exhibit positive Ce anomaly (range: 0.25-2.58), chondritic Y/Ho values (range: 3.3-60), and low (La/Ce)N values (average: 1.8). REE and trace element abundance in Lias cherts indicate that these elements were likely derived from hydrothermal solutions, terrigenous sources, and seawater. The REE patterns of the cherts show that they were probably deposited close to a continental margin.

Background: Locally advanced colorectal cancers are best treated with multivisceral resections. The aim of this study is to evaluate early and late results after multivisceral resections.Methods: All patients operated for primary colorectal cancer between 2001 and 2010 were -reviewed. These were compared within the patients underwent single organ and multivisceral resections: demographics, tumor and procedure related parameters, perioperative results, early oncological outcomes and 5-year survival.Results: A total of 354 patients (59.6 ± 13.8 years old, 210 [59.3%] males) were abstracted. Ninety (25.4%) patients underwent multivisceral resections for clinical T4 tumors and en-bloc R0 resection was achieved in 82 (91.1%). Only 31 (34.4% and 8.8% of clinical T4 and all cancers, respectively) cases had actual adjacent organ invasions (pT4). Males (20%) had lower risk for locally advanced tumors than females (33.3%) (p < 0.05). PT4 cancers were more common, if the clinical T4 tumor is located in the colon (48.8% vs 21.3%; p < 0.01). Laparoscopy was seldom initiated and the risk of conversion was higher in clinical T4 tumors (p < 0.05). The rates of sphincter-saving procedures were not different. Operation time, bleeding and transfusion requirements increased when multivisceral resections were necessitated (p < 0.05), but hospital stay, complications and 30-day mortality rates were similar. The 5-year survival rates were identical (p > 0.05).Conclusions: Clinical T4 tumors are not rare and more common in women. An actual invasion (pT4) may be observed in one third of all clinical T4 tumors, and more frequent in colon cancers. An en-bloc, R0, multivisceral resection may be achieved in most cases. Multivisceral resections do not alter the rates of sphincter-saving procedures, morbidity and 30-day mortality; do not worsen survival but increase operation time, intraoperative bleeding and perioperative transfusion requirements.
