Çobanoglu, Ufuk; Melek, Mehmet; Kara, Volkan; Mergan, Duygu
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.

Akpinar, A.; Kaygusuz, K.
Southeastern Anatolia Project (GAP) region in Turkey is rich in water for irrigation and hydroelectric power. The Euphrates and Tigris Rivers represent over 28% of the nation's water supply by rivers, and the economically irrigable areas in the region make up 20% of those for the entry country. Turkey has a total gross hydropower potential of 433 GWh/yr, but only 125 GWh/yr of the total hydroelectric potential of Turkey can be economically used. By the construction of new hydropower plants, 36% of the economically usable potential of the country would be tapped. The GAP region has a 22% share of the country's total hydroelectric potential, with plans for 22 dams and 19 hydroelectric power plants. Once completed, 27 billion kWh of electricity will be generated annually. (C) 2011 Elsevier Ltd. All rights reserved.

Gezen, Cem; Kement, Metin; Altuntas, Yunus E.; Aksakal, Nihat; Okkabaz, Nuri; Civil, Osman; Vural, Selahattin; Oncel, Mustafa
Background: LigaSure™ (Covidien, Mansfield, MA) has been used in cases undergoing laparoscopic colon and rectal resections. This study aims to analyze the efficacy and safety of the 5-mm and 10-mm devices. Subjects and Methods: Patients who received a laparoscopic or hand-assisted laparoscopic operation for a tumor located in the sigmoid colon or rectum since 2006 were abstracted from a prospectively designed database, and findings were analyzed in two groups based on size of the device used during the procedure. The videotapes of the procedures were watched, and operation reports were read to obtain further information on specific intra- and postoperative complications. Demographics, tumor and operation-related information, and postoperative data were compared. Results: Among 215 (128 [59.5%] males; median age, 59.5±13.8 years) patients, data obtained from the 5-mm (n=32) and 10-mm (n=183) groups were identical regarding demographics and data related to tumor (localization and stage) and operation (number of harvested lymph nodes, conversion rates, operation time, intraoperative bleeding, transfusion requirement, reoperation rates, complications, 30-day mortality, and length of hospital stay). However, more patients underwent an anterior resection in the 10-mm group than in the 5-mm group (31.7% versus 15.6%, P<.05). Further analyses found device-related bleeding in 8 (3.7%) cases (2 [6.3%] versus 6 [3.3%] in the 5-mm versus 10-mm group, respectively, P>.05), requiring further attempts for hemorrhage control (n=6), conversion to open surgery (n=1), or relaparotomy (n=1). Conclusions: The 5-mm and 10-mm LigaSure devices are similarly effective and safe during laparoscopic sigmoid colon and rectal resections. Severe bleeding from larger vessels may be observed, requiring conversion to open surgery or relaparotomy.

Cakir, Tufan; Livaoglu, Ramazan
The paper describes a simple, efficient and reasonably accurate analytical model for analysis of backfill-rectangular tank-fluid interaction systems. The presented model uses Housner's two-mass approximation for fluid interaction and mass-spring-dashpot system for backfill interaction and accommodates a variety of features that may affect the behavior of rectangular tanks including fluid volume, backfill geometry, soil properties and flexible/rigid wall types. Unlike the conventional finite element and the finite difference models that require considerable effort and knowledge to prepare the input data, the proposed model requires only a few pieces of data to define the problem and control the analysis. A series of finite element simulations were also fulfilled on two real rectangular tanks subjected to backfill and fluid effects. A reasonably good accord was obtained comparing the analytical predictions to results from numerical simulations. Thus, it can be stated that the model may be used effectively to perform a broad suite of parametric studies at the design stage and also as a reliable tool for estimating the system behavior. The results obtained from parametric seismic analyses indicated that backfill interaction, wall flexibility and fluid interaction considerably affect the lateral displacements. The sloshing response, however, was not practically affected by the backfill interaction and the wall flexibility.

Öztürk, Serkan; Bayrak, Yusuf
A statistical analysis is made for the eastern part of Turkey in the beginning of 2009 by studying the phenomenon of seismic quiescence as a potential precursor of the main shocks. The results produced four areas having seismic quiescence in the beginning of 2009. These areas are observed to be centered at 39.96°N-40.69°E (around Aşkale, Erzurum), 39.36°N-39.74°E (around Ovaci{dotless}k, Tunceli), 39.02°N-40.52°E (including Elazi{dotless}ǧ and Bingöl), and 38.45°N-42.94°E (Van Lake). Based on the recent results showing 5 ± 1.5 years quiescence before the occurrence of an earthquake in this region, the future earthquake would be expected between 2009. 5 and 2010. 5. The future earthquake occurrence may reach 2012 if we consider the standard deviation of average seismic quiescence as ±1.5 years. We have found that the MW = 6.0 Elazi{dotless}ǧ earthquake on 8 March 2010, followed a seismic quiescence starting about 5 years before the main shock. Thus, special interest should be given to the other regions where the seismic quiescence is observed.

This study aims to forecast the world's, European Union's (EU), and Turkey's electricity energy generation until 2030. For this purpose, the electricity energy sector of the world, EU, and Turkey was overviewed from past to present. The total electricity energy generation for the world, EU, and Turkey were then modelled by using historical energy generation data as years with regression analysis. Data from 1970 to 2004 for Turkey and data from 1980 to 2004 for the world and EU were used for the projections. Electricity energy productions have been forecasted up to year 2030. According to the results, it is determined that cubic (R2 = 0.997) and linear (R2 = 0.993) models for projection of the world's and EU's electricity energy generation, respectively, is fitness while the quadratic (R2 = 0.996) model fits for the projection of Turkey's total electricity energy generation and Turkey will have 0.995% of the world's electricity energy generation in 2030, while the EU will have 8.41% within the world's electricity energy generation in 2030 if the current trend continues.

Karsli, Orhan; Caran, Şemsettin; Dokuz, Abdurrahman; Çoban, Hakan; Chen, Bin; Kandemir, Raif
The Eastern Pontides is characterized by the many of intrusive bodies formed throughout the late Mesozoic-early Cenozoic. Most of these are I-type granitoids, but here, we present for the first time an A-type pluton from the region to assess source characteristics and geodynamic implications. The A-type Pirnalli pluton has a SHRIMP zircon U-Pb age of 81.2±1Ma. It is composed of granite, syenite and quartz monzonite, and its enclaves are monzonitic in composition with elevated Ga/Al ratios and low Mg# (<42). The pluton is dominantly metaluminous (A/CNK=0.88 to 1.00) and belong to shoshonitic and ultra-potassic series. The samples are highly enriched in LREE and show significant negative Eu (Eu/Eu *=0.33 to 0.92), Ba, Nb, Sr and Ti anomalies in the spidergrams. The host rocks and their enclaves posses quite similar Sr-Nd isotopic compositions (I Sr=0.70693 to 0.70736, ε Nd (81Ma)=-2.6 to -2.0, T DM=0.94 to 1.12Ga), pointing to a lower crustal parental magma with a minor contribution of lithospheric mantle. We hypothesize that upwelling of asthenosphere triggered melting of chemically enriched upper mantle and basic magma formed. Melting of lower crust was provided by the underplating of this basic magma. Mixing between lower crust- and mantle-derived melts at depths of lower crust appears to be most reasonable petrogenetic process responsible for generation of the pluton. Sr-Nd isotope modeling suggests mixing of 82-90% of the lower crustal-derived melt with ~10-18% of the mantle-derived melt. Then the hybrid melt ascended to shallower crustal level and underwent a limited fractionation process to generate a variety of rock types. Our data also suggest that the A-type Pirnalli pluton likely formed at an extensional environment of active continental margin throughout the late Cretaceous. Ongoing extension then led to opening of Black Sea as a back-arc basin further north of the Eastern Pontides.

The benefits of taking of aspirin, clopidogrel, and warfarin in relation to cardiovascular mortality and re-hospitalization in chronic heart failure (HF) patients have been called into question. We examined the outcomes (cardiac mortality and/or HF re-hospitalization) in patients discharged from our hospital between January 2003 and July 2009 after hospitalization for chronic decompensated HF. Of 580 HF patients (mean age, 63 ± 13 years; mean ejection fraction, 26 ± 9%, 63% with coronary disease and 37% without coronary disease), 207 patients (36%) died due to cardiovascular reasons, and 313 (54%) required HF re-hospitalization for decompensated HF during a 39 ± 14 month follow-up period. 101 (17%) patients were taking clopidogrel during enrollment in the study. When comparing patients who were on clopidogrel treatment with those who were not, clopidogrel was found to have a beneficial effect on cardiac mortality (27 vs. 38%, P = 0.04). In conclusion, in this observational prospective study, patients who used clopidogrel showed decreased cardiac mortality [HR, 0.566 (95% CI 0.332-0.964), P = 0.036] compared to patients who did not take clopidogrel. Clopidogrel had a beneficial effect on the survival of chronic HF patients in the long term.

The study was designed in a randomized complete block design with five treatments replicated three times. The genotypes were evaluated in terms of forage properties as well as chemical and physical properties of silages in both years. According to the results, the corn genotype had better yield and silage qualities than sunflower genotypes. But crude protein contents of silages of sunflower genotypes were superior in comparison to the corn genotype. Also amongst sunflower genotypes, confectionery Tekirdag and Erzurum landraces had slightly higher silage qualities than oilseed sunflower hybrids.

The present study has been performed to examine the adsorption ability of novel sorbent dehydrated hazelnut husk carbon (DHHC) towards Ni(II) ions from aqueous solution using the batch adsorption technique. The effective factors such as initial pH of the aqueous solution, contact time, initial Ni(II) concentration, adsorbent dosage, and temperature were investigated. The studies were also conducted to understand the effect of some co-existing ions which may be present in aqueous solutions. DHHC showed good adsorption potential for Ni(II) ions. The optimum initial pH value was selected as 5.0. The experimental data fitted well to the Langmuir adsorption isotherm model. Among the kinetic models tested for the adsorption of Ni(II), the pseudo-second-order model showed a good fit of the kinetic data. The thermodynamic parameters including the Gibbs free energy (ΔG), enthalpy (ΔH), and entropy (ΔS) changes indicated that the adsorption of Ni(II) ions onto DHHC was feasible, spontaneous, and exothermic in the temperature range of 25-55°C. The results of this study showed the effectiveness and feasibility of DHHC for the removal of Ni(II) ions from aqueous solution.

This study was performed in one of the most important parks of Turkey, the Hatila national park, where a gold mining activity is planned to be conducted. For this purpose, 40 moss samples were collected for heavy metal and radioactivity measurements. A radioisotope excited Xray fluorescence analysis using the method of multiple standard additions was applied for the elemental analysis of mosses collected in Hatila valley national park in the Eastern Black Sea region of Turkey. An annular 50 mCi 241Am radioactive source and annular 50 mCi 55Fe radioactive sources were used for excitation of characteristic K-X rays. An Si(Li) detector which had a 147eV full width at half maximum for 5.9 keV photons was used for intensity measurements. A qualitative analysis of spectral peaks showed that the samples contained potassium, calcium, titanium, iron, tin and barium with average concentrations of 230, 5340, 450, 70, 4 and 33 mg.kg -1, respectively. 137Cs and 40K using gamma-ray spectroscopy were determined in 40 moss species collected from the Hatila valley national park. Average activity concentrations of 40K and 137Cs were found to be 103 and 272 Bq.kg -1, respectively. As the region was shown to be heavily contaminated by the Chernobyl accident, the high concentration of 137Cs could be due to this accident. The results are compared with those obtained in different parts of the world where gold mining activities are being conducted. The possible consequences of these results are briefly discussed from the point of potential hazards to ecology and human health.
