Construction Of Novel Cyanobacteria-Based Biological Photovoltaic Solar Cells: Hydrogen And Photocurrent Generated Via Both Photosynthesis And Respiratory System

Carbas Bezgin, Buket | Güler, Mensure | Yücel, Kamile | Yildiz, Hüseyin Bekir

Biological photovoltaic (BPV) cells use biological organisms in order to produce clean electrical power by capturing solar energy. In this study, a cyanobacteria based BPV cell was constructed and it generated H2 gas and photocurrent via photosynthesis and respiratory system. This kind of BPV cell was constructed in which the cathode and photoanode are gold electrodes coated with different conjugated polymers and these polymers are combined to Pt or Au nanoparticles with oligoaniline bonds. Unlike the cathode electrode, a kind of cyanobacteria (Leptolyngbia sp.) was used in the design of photo ...Daha fazlası

EROL, Erkan | APAYDIN, Umut | YILDIZ, Ramazan | YILDIZ, Ayşe | ERTURAN, Sinem | GÖKMEN, Derya | AKKOYUN SERT, Özlem | ÜNÜVAR, Bayram Sönmez | GERÇEK, Hasan | ELBASAN, Bülent

Background/aim: Lumbar instability is an important condition that can be seen frequently in people with low back pain, affecting both the progression and the choice of appropriate exercise. The Lumbar Spine Instability Questionnaire (LSIQ) is a simple and low-cost tool for evaluating disturbed back stability in people with low back pain. The aim of this study is to develop the Turkish version of the LSIQ (LSIQ-T) and to evaluate its psychometric properties using the Rasch model. Materials and methods: One hundred participants with chronic low back pain completed the LSIQ-T. The LSIQ-T was repe ...Daha fazlası

Investigation of Physical Activity, Fear of Falling, And Functionality in Individuals With Lower Extremity Lymphedema

ŞAHBAZ PİRİNÇÇİ, Cansu | CİHAN, Emine | ÜNÜVAR, Bayram Sönmez | GERÇEK, Hasan | AYTAR, Aydan | BORMAN, Pınar

Purpose To investigate the fear of falling, physical activity, and functionality in patients with lymphedema in the lower extremities. Methods Sixty-two patients who developed stage 2–3 lymphedema in the lower extremities due to primary or secondary causes (age: 56.03 ± 7.83 years) and 59 healthy controls (age: 54.61 ± 5.43 years) were included in the study. The sociodemographic and clinical characteristics of all individuals included in the study were recorded. In both groups, fear of falling was evaluated with the Tinetti Falls Efficacy Scale (TFES), lower extremity functionality with the Lo ...Daha fazlası

Fossil mollusc shells are used for dating geological materials because they are well preserved throughout geological time. In this study, the radicals in the structure of fossil mollusc shells (Dreissena iconica, Valvata piscinalis, Bithynia tentaculate, Unio pictorum) collected from the Eastern Part of Old Konya Lake in Türkiye were investigated by EPR technique. For all fossil shells, microwave and temperature dependence of the signals were examined, and the signals suitable for dating are discussed. Characteristic features of intrinsic and impurity-related radicals were identified and the i ...Daha fazlası
