Factors Affecting the Entrepreneurial Intentions of Women Entrepreneur Candidates: A Structural Equation Model
The aim of this study was to reveal factors influencing the entrepreneurial
intentions of women entrepreneur candidates using the theory of planned behaviour
(TPB). The authors employ the TPB, in which intentions and aspiration towards being
an entrepreneur are regarded as resulting from attitudes, perceived behavioural control,
and subjective norms. A questionnaire was conducted on 252 women entrepreneur
candidates who attend the vocational course, OMEK, which belongs to Eskişehir
(Turkey) Odunpazarı Municipality. In the research model that has been proposed within
the scope of TPB, the Structural Equation Model (SEM) was used in order to reveal the
relationship between the factors influencing entrepreneurial intentions and evaluating
the conformity of the model. According to the results of the SEM analysis, it was
determined that the latent variables, which are attitudes, subjective norms and perceived
behaviour control, have a positive effect on entrepreneurial intentions. In the study, the
perceived behavioral control variable was calculated to be 0.38, 0.06 and 0.44,
respectively, direct, indirect and total effect on an aspiration towards being an
entrepreneur. In summary, it is determined that the perceived behavior control factor is
the most important predictor of entrepreneurial intention and an aspiration towards
being an entrepreneur factor
Laboratuvardan Kliniğe Transplantasyon Pratiği
Transplantasyon; Temel Tıbbi Bilimler, Moleküler Tıp, Genetik ve İmmünolojiden klinik uygulamalardan destek alan multidisipliner bir tıp dalıdır. Temel bilimlerdeki başarılı çalışmaların kliniğe uygulanması, klinikte karşılaşılan sorunların da, oluşturulan deneysel hayvan modellerinde irdelenmesi, elde edilen bilgilerin klinik uygulamalara aktarılması; diğer deyişle tecrübelerin “Translational” özellikli olması günümüz transplantasyon çalışmalarında bir gerekliliktir. İmmün sistemin bileşenlerinin ve reaksiyonlarının iyi bilinmesi, hücreler arası ilişkilerde greftin reddi ya da kabul edilmesinin şartlarını doğru anlamak ve uygun laboratuvar yöntemleri ile klinik durumun aydınlatılması transplantasyonda stratejik önemdedir. Bu nedenle, klinik transplantasyon çalışmaları yapanlar temel bilimler bilgileri ile de donanımlı olmalıdırlar. Multidisipliner bir dal olma bilinci ile yapılan klinik transplantasyon çalışmalarında başarı yakalanmaktadır. Laboratuvardan Kliniğe Transplantasyon kitabımızda tüm yönleri ile transplantasyonun organizmaya etkileri ve bunların klinik sonuçlarını, çalışmalarımızın ışığında sunmayı ve tartışmayı hedefledik.

EPIdemiology of Surgery-Associated Acute Kidney Injury (EPIS-AKI) : Study protocol for a multicentre, observational trial
More than 300 million surgical procedures are performed each year. Acute kidney injury (AKI) is a common complication after major surgery and is associated with adverse short-term and long-term outcomes. However, there is a large variation in the incidence of reported AKI rates. The establishment of an accurate epidemiology of surgery-associated AKI is important for healthcare policy, quality initiatives, clinical trials, as well as for improving guidelines. The objective of the Epidemiology of Surgery-associated Acute Kidney Injury (EPIS-AKI) trial is to prospectively evaluate the epidemiology of AKI after major surgery using the latest Kidney Disease: Improving Global Outcomes (KDIGO) consensus definition of AKI. EPIS-AKI is an international prospective, observational, multicentre cohort study including 10 000 patients undergoing major surgery who are subsequently admitted to the ICU or a similar high dependency unit. The primary endpoint is the incidence of AKI within 72 hours after surgery according to the KDIGO criteria. Secondary endpoints include use of renal replacement therapy (RRT), mortality during ICU and hospital stay, length of ICU and hospital stay and major adverse kidney events (combined endpoint consisting of persistent renal dysfunction, RRT and mortality) at day 90. Further, we will evaluate preoperative and intraoperative risk factors affecting the incidence of postoperative AKI. In an add-on analysis, we will assess urinary biomarkers for early detection of AKI. EPIS-AKI has been approved by the leading Ethics Committee of the Medical Council North Rhine-Westphalia, of the Westphalian Wilhelms-University Münster and the corresponding Ethics Committee at each participating site. Results will be disseminated widely and published in peer-reviewed journals, presented at conferences and used to design further AKI-related trials. Trial registration number NCT04165369
Offshore Farming of the Mediterranean Amberjack (Seriola dumerili) in the Northeastern Mediterranean
The growth rate, survival, and feeding parameters of Mediterranean amberjack (Seriola dumerili Risso, 1810) cultivated in offshore cages in the Gulf of İskenderun (Hatay, Turkey) were investigated from July 2006 to March 2008. Two offshore cages (339 m3) were placed at a depth of 10 m in a sheltered area 500 m off the coast. Juveniles (101.97±14.54 g), caught with seine nets 400-1200 m from the coast, were stocked in the cages at 250 per cage. Fish in one cage, Group A, were fed commercial pellets for all 20 months whilst fish in the second cage, Group B, were fed pellets for the first 16 months and frozen sardines for the following four. The mean live weight, survival, feed conversion ratio, daily feed consumption, and water quality parameters were recorded monthly. Group B reached a significantly (p<0.05) greater weight (2785.00±64.91 g) than Group A (2441.14±38.13 g). Food conversion ratios ranged 1.16-2.46 for group A and 1.10-2.28 for group B, low when compared with other studies on amberjacks in the Mediterranean. Average mortality was 25%, due to a Zeuxapta seriolae (Monogenea: Heteraxinidae) infection in December 2006 (20%) and fish handling for measurement in June 2007 (~5%). The farmed amberjacks had significantly higher protein and lipid contents than their wild counterparts at the end of the 20-month feeding period. Amberjacks found frozen sardines more appealing than pellets, especially during the winter. In conclusion, it is advised to feed Mediterranean amberjack frozen sardines or other trash fish during the winter grow-out period. Their rapid growth rate, as well as their adaptability to farming, make offshore net cages a promising system for the aquaculture of this species

Distinguishing opaline silica polymorphs from alpha-cristobalite in Gedikler bentonite (Usak, Turkey)
X-ray diffraction (XRD) patterns of the Gedikler (Esme-Usak) bentonite samples show the presence of silica polymorphs which have a characteristic XRD reflection at ca. 4.04 angstrom. Opaline silica polymorphs, opal-C and opal-CT, can be misidentified as alpha-cristobalite using standard XRD patterns of the raw bentonite samples. In order to distinguish opaline silica polymorphs from alpha-cristobalite, NaOH dissolution (0.5 M and 10 min.), phosphoric acid (H3PO4) digestion (240 degrees C, 15 min) and thermal treatment (1150 degrees C, 48 h) were applied. After these applications, samples were examined by XRD and Fourier transform infrared (FTIR) spectroscopy. It was observed that the 101 diffraction maximum at ca. 4.04 angstrom almost disappeared after NaOH dissolution and phosphoric acid digestion. Moreover, the crystal order and the diffraction maxima at 4.04 angstrom increased dramatically after thermal treatment. Besides, FTIR spectra of the samples are similar to untreated ones after NaOH dissolution, whereas they are comparable to opal-A after phosphoric acid digestion. Furthermore, the phosphoric add digestion residues, which consist mainly of opal-A, were transformed to alpha-cristobalite during the thermal treatment. Based on these studies, it was concluded that the Gedikler bentonite samples contain mainly opal-CT, opal-A and minor amounts of alpha-cristobalite. The result of the phosphoric acid digestion method and the NaOH dissolution method yielded comparable results. (C) 2012 Elsevier B.V. All rights reserved
