Gunshot injuries of the popliteal vessels: A report of three cases
No full textLower extremity vascular injuries occur due to gunshot wounds, traffic accidents, penetrating and blunt injuries, or industrial injuries. Gunshot wounds with vascular injuries have been increased among the civilian population. Lower extremity gunshot wounds have severe and acute complications of bone fractures, abundant bleeding, hypovolemic shock, soft tissue disruption, acute ischemia, neurological deficit, limb loss, or even death. The amputation rate of the popliteal injuries differs between 27% and 54%. In this paper, preoperative management and surgical experience in the popliteal region vascular injuries in three massively impaired cases were presented. Different surgical approaches performed in these patients due to the variety of pathologies were also discussed. [Arch Clin Exp Surg 2017; 6(4.000): 228-232
Comparing retinal vascular changes in patients who underwent carotid endarterectomy
No full textBackground: This study aims to investigate ocular ischemia in patients who were candidates for carotid endarterectomy (CEA) and postoperative flow changes in orbital arteries, and demonstrate the impact of these flow changes on the eye and ocular ischemia
Numerical Study of the Effects of Lambda and Injection Timing on RCCI Combustion Mode
No full textReactivity Controlled Compression Ignition (RCCI), which is a low temperature combustion mode based on the prİnciple of working with dual fuel, has attracted the attention of researchers in recent years due to its advantages such as high thermal efficiency, low NOx and soot emissions, and controllability of combustion. In this study, the effects of injection timing and lambda on RCCI combustion mode were investigated numerically by validating the experimental data with Converge CFD software. A four-cylinder, four-stroke gasoline direct-injection engine with a compression ratio of 9.2 was used in RCCI combustion mode at an engine speed of 1000 rpm. The maximum cylinder pressure also increased and RCCI combustion was advanced while the injection timing was advanced. The highest peak pressure was obtained at SOI=-50°CA aTDC, and the lowest peak pressure was obtained at SOI=-25°CA aTDC. Similarly, the highest peak HRR value was acquired as 213 J/°CA at SOI=-50°CA aTDC. It has been observed that as the lambda decreases, the maximum cylinder pressure increases, and combustion advances. In addition, the heat release rises with a decrease in lambda value. The maximum heat release rate was acquired as 77.91 J/°CA at λ=1.2. The results show that injection timing and lambda have a great influence on RCCI combustion mode and the combustion phase can be controlled with these parameters. © 2022 by the Author(s).The Scientific and Technological Research Council of Turkey (TÜBITAK) provided financial support for Hamit Solmaz and Serdar Halis to perform this research.

Translation and westernisation in Turkey (from the 1840s to the 1980s)
No full textThis thesis examines the role and function translations played in Turkish history,
especially within the framework of its Westernisation movement from the mid-nineteenth
to the late twentieth centuries. A descriptive approach is adopted, aiming to identify
cultural patterns which shape and reflect translational decisions and help to a better
portrayal of the socio-cultural context of translation during the time span examined. To
this end, the thesis seeks to describe in detail historical, political, literary and linguistic
factors which have affected the translation activity.
The main assumption of this thesis is that acculturation was used as the main
strategy in translations from Western languages during the periods which were marked
with an extensive translation activity, especially during the nineteenth century and the first
decades of the Republican era. This acculturation strategy not only helped to enrich the
target literary system, bringing new literary models (genres), new subject matter,
developing the language and giving rise to a new Turkish literature, it also had an effect
upon the broader socio-cultural polysystem, especially on the process of identity creation.
The analysis of the social, political and cultural conditions and policies suggests
that the status given both to the source and target cultures has been the main factor for the
acculturation. As examined in the last part of the thesis, a shift of power relations in the
Turkish context, especially after the 1980s, marked a new kind of an acculturation
strategy and a certain movement of resistance.
The thesis concludes that there is need to know more about different translation
histories in order to learn more about the acculturation process and to move beyond a
Eurocentric view, and an interdisciplinary approach should be taken for such research
