Çavdar, Ahmet; Ozkul, MH; Atahan, HN; Dogan, UA; Pekmezci, BY; Sengul, O
In this study, four different types of fibers are added to cement mortars and it is aimed to investigate their mechanical contributions to mortars, comparatively. Polypropylene (PP), carbon (CF), glass (GF) and polyvinyl alcohol (PVA) fibers are chosen as fibers to research. These fibers are added into mortars five different ratios (0.0%, 0.5%, 1.0%, 1.50% and 2.0%) by volume. The mechanical properties investigated are flexural strength, deflection and compressive strength of the cement mortars. These properties are determined under two conditions, one of two is saturated surface dry (SSD) and second one is oven dry (OD). It is concluded that each fibers contributes the mechanical properties of mortars in different addition ratios. PVA fibers show the best performance of the fibers investigated in this study. Fibers present best performance at OD condition.

Sezer, Ismet
In this study, the effects of diethyl ether (DEE)-diesel fuel blends on the performance of a diesel engine investigated experimentally. The blends were prepared with the addition of 2.5, 5, 7.5, and 10 vol. % of DEE with a specified amount of diesel fuel. In the experiments, a single cylinder direct injection (DI) diesel experimental engine was used and compression ratio was fixed at 20. The experiments were performed with neat diesel fuel and DEE-diesel fuel blends at various engine speeds and wide open throttle conditions. The results of the study show that DEE addition to diesel fuel causes to decrease in engine performance parameters, i.e., brake mean effective pressure, brake torque and brake power. The decrement in performance parameters increased with increasing blending ratio. The maximum decrement in brake mean effective pressure was obtained with DEE10 blend as about 5.1%. However, brake thermal efficiency increases and brake specific fuel consumption decreases up to 7.5% DEE blending ratio. The maximum increment in brake thermal efficiency was obtained with DEE7.5 blend as about 10.9%. The same fuel blend gives about 8.7% reduction in brake specific fuel consumption. Additionally, exhaust gas temperature decreases and air excess coefficient increases with increasing DEE blending ratio.

Pirlanta, Ismail
Khurasan province, considering its geopolitical position and great importance was held under the control of various authorities throughout the history. No doubt the Turkish states are among they too. The region which met with the Turkish culture thanks to Ghaznavids became later a Turkish country in every regard in the period of Saljuqids. The Turcomans which were brought to Khurasan by the famous ruler of Ghaznavid State, Mahmud, succeeded to emerge as a political authority. A progress has been in all areas in Khurasan During period of Saljuqids. These progresses set a good example for other states. Particularly in cultural meaning, Khurasan's cultural heritage offered benefits for masses in the extension of a vaste geography. On the other hand some applications on religious and social life of Great Saljuqids upon the managed class (tab'a) have also affected people in the region and left deep traces on geographies. Examination of these implementations will contribute great to the understanding of the social structure of the geography of Khurasan in the period of Saljuqids. In this context, we want to touch upon some applications on religious and social life of Great Saljuqids upon the people and their effects.

Background: This study aims to evaluate the characteristics of patients with traumatic rupture of diaphragm (TDR), the diagnostic and therapeutic approaches used in these cases and and the outcomes of the patients. Methods: Forty-one patients (31 males, 10 females; mean age 41.9 years; range 7 to 71 years) with thoracoabdominal trauma and diagnosis of TDR who were treated in our clinic between January 2000 and January 2010 were analyzed retrospectively. The patients were statistically compared in terms of age, gender, the time of diagnosis (early or late), the diagnostic procedures that were performed, whether the diagnosis of rupture was made during or after the operation, the localization of the rupture, the diameter of the rupture, accompanying injuries, the surgery performed, mortality and morbidity and the trauma injury severity score. Results: The etiology for the diaphragmatic rupture was blunt trauma in 43.9% and penetrating trauma in 56.10% of the patients. 85.36% of the patients were diagnosed in early stage and 14.64% in late stage. Herniation dignosis was made radiologically in 118 (43.9%) patients and diaphragmatic rupture was detected during the operation in 23 patients (56.1%). Twenty-nine (70.73%) patients had thoracotomy, seven (17.02%) patients had laparatomy and five (12.19%) patients had thoracotomy plus laparatomy. The overall mortality rate was 14.63% (n=6). Conclusion: Traumatic diaphragmatic ruptures may have a fatal course depending on the strangulation of the herniating abdominal viscera. Traumatic diaphgram rupture should be suspected in all multitraumatic patients and these cases shuld be seriously evaluated for the definitive diagnosis and treatment plan.

Günaydin, Murat; Adanur, Suleyman; Altunisik, Ahmet Can; Sevim, Baris
In this study, it is aim to perform the construction stage analysis of suspension bridges using time dependent material properties. Fatih Sultan Mehmet Suspension Bridge connecting the Europe and Asia in Istanbul is selected as an example. Finite element models of the bridge are modelled using SAP2000 program considering project drawing. Geometric nonlinearities are taken into consideration in the analysis using P-Delta large displacement criterion. The time dependent material strength variations and geometric variations are included in the analysis. Because of the fact that the bridge has steel structural system, only prestressing steel relaxation is considered as time dependent material properties. The structural behaviour 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 is seen that construction stage analysis has remarkable effect on the structural behaviour of the bridge.

Objective: Enhanced external counterpulsation (EECP) is a noninvasive treatment that is proven safe and effective in patients with coronary artery disease (CAD) and heart failure (HF). The aims of this study are to investigate the clinical effects of EECP therapy in patients with symptomatic CAD and chronic HF, and to find out an answer to the question: Does EECP therapy have any effect on the prognostic markers of HF? Methods: This study was designed as a prospective cohort study. A total of 68 consecutive patients with symptomatic CAD and chronic HF referred to EECP therapy were enrolled in this study between November 2007 and December 2010; 47 patients (39 males and 8 females, 65 +/- 7, years), have undergone EECP treatment, and 21 patients (20 males and 1 female, 62 +/- 10 years), who did not want to participate in the EECP program comprised the control group. Statistical analysis was performed using t tests for dependent and independent samples, Mann-Whitney U test, Chi-square and Fischer exact tests. Results: EECP therapy resulted in significant improvement in post-intervention New York Heart Association functional class (p<0.001), left ventricular ejection fraction (p<0.001), B-type natriuretic peptide levels (p<0.003), uric acid levels (p<0.05), free-T3/free-T4 ratio (p<0.034) and mitral annular E (p<0.05) velocity, compared with baseline, a finding not evident in the control group. Conclusion: EECP treatment significantly improved clinical and some biochemical parameters, which are mostly prognostic markers in patients with symptomatic CAD and chronic HE (Anadolu Kardiyol Derg 2012; 12:214-21)

Objectives The purpose of this retrospective study was to compare the mean platelet volume between the patients with acute deep vein thrombosis (DVT) and control subjects. Methods Data were collected retrospectively from the patients' medical records. The study group consisted of 110 patients with newly diagnosed acute DVT in the lower extremities. An age, gender, and body mass index-matched control group consisted of 98 patients with normal duplex ultrasound findings. We compared the mean platelet volume in patients with acute DVT and control participants. Results There was no significant difference between the study and control groups in mean platelet volume (8.8 +/- 1.6 vs 8.7 +/- 1.3 fl, respectively; p>0.05). Age (p=0.899), body mass index (p=0.43), gender (p=0.466), and platelet count (p=0.886) were statistically similar in both groups. Conclusions There was no significant difference in mean platelet volume between patients with acute DVT and the control group. According to our result, we propose that mean platelet volume should not be considered as an index of acute DVT.

Mean platelet volume (MPV) is increased in chronic heart failure (CHF) and is an independent predictor of mortality in CHF patients. It is not known whether enhanced external counterpulsation (EECP) therapy leads to decreased MPV values or not. The purpose of this study was to examine the effects of EECP on platelet count and MPV values and to assess the influence of MPV on the risk of death and recurrent ischemic events in ischemic CHF patients. A total of 68 ischemic heart failure patients with CHF symptoms and refractory angina pectoris were included in the study, 47 consecutive patients (39 males and eight females) aged 44-82 years. Although follow-up period started after completion of EECP in treated patients, control group follow-up started at the end of 7-week treatment without EECP. All patients were monitored for a mean duration of 13 +/- 8 months (range, 1-36 months). The primary endpoints of the study were effects of EECP treatment on platelets after treatment period (7 weeks) and the recurrence of ischemic events. Secondary endpoint was cardiovascular death during the follow-up period. We observed a significant increase in platelet count and decrease in MPV levels (P=0.044 and P=0.004, respectively) in the control group. There were no significant differences in platelet count and MPV levels in the EECP group (P>0.05). After the treatment period, New York Heart Association functional classification (2.60 +/- 0.75 vs. 1.72 +/- 0.68, P<0.001) and Canadian Cardiovascular Society functional classification of angina (2.50 +/- 0.90 vs. 1.60 +/- 0.74, P<0.001) improved in patients with EECP treatment. In our study, we found that EECP therapy had a neutral effect on MPV values and platelet count Blood Coagul Fibrinolysis 23:127-131 (C) 2012 Wolters Kluwer Health vertical bar Lippincott Williams & Wilkins.

In this work, elasto-plastic stress analysis of single lap joints with and without protrusion in adhesive bondline subjected to tension and bending was carried out using 2D non-linear finite element analysis and confirmed experimentally. AA 2024-T3 aluminum adherends were bonded with SBT 9244 film adhesive. The protrusion was obtained by extending the adhesive film by 2 mm from the overlap length at both overlap ends. Three different adherend thicknesses and overlap lengths for each loading and bondline type were used. The joints with and without protrusion, for comparison, were loaded with the same load for each adherend thickness and overlap length. Finally, it was observed that the protrusion reduces the strength in the joint under tension, while the protrusion increases the strength in the joint under bending.

Sevim, Baris; Altunisik, Ahmet Can; Bayraktar, Alemdar; Akköse, Mehmet; Adanur, Suleyman
Using experimental methods, this study presents the estimation of the dynamic and static ( secant) elasticity modules of a prototype arch dam. These experimental methods are ambient vibration tests, uniaxial compression tests, and ultrasonic velocity tests. Implementation of the methods on a prototypical arch dam-reservoir-foundation model of the dam, constructed under laboratory conditions, allows estimation of the elasticity modules. Random impact loads excite the arch dam during ambient vibration testing, which creates response signals for measurement. Commercially available software transfers the signals, and processing those signals allows estimation of the experimental natural frequencies of the arch dam. Analysis of a three-dimensional (3D) finite element model (FEM) of the arch dam determines natural frequencies. The estimation of the elasticity modules of the arch dam arises from a comparison of the experimental and analytical frequencies. The uniaxial compression tests use several specimens of the fresh and hardened concrete of the prototype model, and those tests provide the compressive strengths and stress-strain relationships. The ultrasonic velocity tests apply several velocity measurements to the arch dam and foundation, resulting in estimation of the elasticity modulus from empirical equations related to concrete mix design, compressive strength, and velocity values. This study discusses the difficulties of the determination of the elasticity modulus and suggests that ambient vibration testing and the finite element method are useful for overcoming these difficulties.

In this study, effects of lactation length, calving year and service period on lactation milk yield of Holstein Friesians were modeled with multiple regression and artificial neural networks (ANN) and compared goodness of fit of models. Analyses were carried on five lactations milk yields of 305 Holsteins calved at 2006, 2007 and 2008 years. After several experiments, hidden layer number was taken one and hidden nodes number were found three for the chosen architecture. Moreover, convergence criteria, maximum iteration number and epoch number were taken as 1.10(-6), 50 and 20, respectively. Adjusted coefficient of determination (R-2),root mean square error (RMSE), mean absolute deviation (MAD), mean absolute percentage error performance criteria (MAPE) were used for comparison of artificial neural network and multiple linear regression models goodness of fit. After analysis R-2 values were found among 0.62-0.85 for the five lactations with neural networks model. RMSE, MAD and MAPE criteria also were found among 480.9-1682.8, 325.2-1381.7 and 6.1-20.2, respectively. These criteria were found for R-2, RMSE, MAD and MAPE among 0.30-0.75, 1964.8-30008.7, 1576.6-2458.3 and 24.7-35.6, respectively for multiple linear regression. When the models were compared, artificial neural networks model gave better fit than multiple linear regression models. Consequently, artificial neural networks was determined an alternative method to multiple regression analysis.

Atamturktur, S.; Sevim, B.
This article discusses a combined analytical and experimental study on the nonlinear seismic performance of two Guastavino-style masonry domes located in the United States. The seismic performance of these masonry domes is simulated with nonlinear finite-element (FE) models. To support the assumptions and decisions established during the development of the FE models, the vibration response of the domes is measured on-site and systematically compared against the numerical model predictions. Linear FE models are developed that are in close agreement with the measured natural frequencies and in visual agreement with the measured mode shapes. Next, these linear models are extended into the nonlinear range by incorporating the Drucker-Prager damage criterion. Finally, nonlinear FE models are used to assess the performance of these two domes under seismic loadings obtained from the 1940 El Centro earthquake acceleration records. The predicted displacements and internal tensile stress levels are used to make inferences about the potential behavior of these two buildings under the selected earthquake load.

Aim: The aim of this study was to review cases with isolated hemothorax after thoracic trauma, to assess the diagnostic and treatment methods, and to discuss the determining factors of morbidity and mortality. Material and Method: A total of 57 patients were examined retrospectively. All patients underwent tube thoracostomy and underwater seal as the initial treatment approach. Emergency thoracotomy was performed on cases with continuing drainage from the chest tube, expanding hemothorax on the posteroanterior (PA) chest x-ray, and with hemodynamic instability. Result: Hemothorax occurred as a result of penetrating trauma in 31 (54.38%) and due to blunt trauma in 26 (45.61%) cases. Of the cases, 49 (85.96%) underwent tube thoracostomy drainage. All the 8 cases (14.03%) that underwent emergency thoracotomy had penetrating trauma. Mortality occurred in one patient (1.75%) who had penetrating trauma and who underwent emergency thoracotomy. The morbidity rate in patients with blunt trauma was significantly higher than those with penetrating trauma (p<0.0001). Discussion: Accurate diagnosis and appropriate surgical intervention in cases with traumatic hemothorax is essential for reducing the morbidity and mortality. Chest tube insertion and underwater seal application should be the initial treatment modality and successful in most cases. Emergency thoracotomy is life-saving in indicated patients. The need for thoracotomy is higher in isolated hemothorax due to penetrating chest trauma.

PURPOSE We aimed to present the short- to mid-term results of endovenous laser ablation (EVLA) procedures that were used to treat great saphenous vein (GSV) insufficiency. MATERIALS AND METHODS This prospective study was conducted between December 2009 and January 2011. A total of 112 incompetent GSVs were treated using EVLA with a 940 nm wavelength laser. Ninety patients were treated for varicose veins with saphenous reflux, including 36 females (40%) and 54 males (60%). These patients' ages ranged from 17 to 79 years (median, 48 years). After the EVLA, the patients were monitored using duplex ultrasonography and were assessed clinically at 1 week and 1, 3, 6, and 12 months after the surgery. The patients were scheduled for a three-day examination after the EVLA to assess the level of pain that each patient was experiencing in each limb. RESULTS At the end of a one-year follow-up period, the postprocedural duplex scans revealed a total occlusion of the treated GSVs in 88 (97%) patients and a sub-total occlusion in two (2%) patients. The average modified clinical, etiological, anatomical, and pathological score was significantly decreased at 12 months. The following complications were observed in the present study: hypoesthesia (11%), swelling and induration (5%), skin pigmentation (5%), deep vein thrombosis (1%), erythema (1%), and bleeding (1%). The mean visual analog pain score for the entire procedure was 3.14 +/- 1.06. CONCLUSION Our short- and mid-term results of the EVLA procedure were satisfactory, and the results of this study reaffirmed the safety and effectiveness of an EVLA using a 940 nm wavelength for the treatment of GSV insufficiency.
