Turkey Jerky as a Potantial Meat Snack

The research was aimed to obtain a product with high nutritional value and long shelf life called as Turkey Jerky. It was produced with turkey breast meats which marinated with 7 different spices (Salvia rosmarinus (R), Thymus vulgaris (T), Pimenta racemosa (P), Origanum majorona (M), mixed spicy (MX) and control group (C)), vinegar, olive oil, soy sauce and liquid smoke. At the end of the marination, turkey breast meats were dried in the drying oven and kept in room conditions for 30 days after vacuum packaging. Microbiological, chemical, and sensory analyses were performed for treatments on the 0, 15 and 30 days. For turkey meat, the moisture, pH, ash, water activity (aw), fat and protein contents were determined as 72.34plusmn%253B 1.21, 5.83 plusmn%253B 0.02, 1.18 plusmn%253B 0.01, 0.972 plusmn%253B 0.001, 1.05 plusmn%253B 0.12 and 27.30 plusmn%253B 0.24 %25, respectively. There were significant differences in treatments all chemical properties than control samples. Salvia rosmarinus and Pimenta racemosa samples had the highest protein and ash content%253B Origanum majorona samples had the highest fat content. After marination, both moisture content and water activity values for all samples had decreased significantly. Otherwise, pH values had increased slightly. TBA value was found in the least control group for the beginning of the storage and the treatments had increasing effect on TBAs values. Origanum majorona samples and Pimenta racemosa samples had lower TBA values than other treatments. However, control and Origanum majorona samples have highest the differences between 0 and 30 days for TBA values. Besides, mix spicy treatment had the lowest differences for 30 days. According to the microbiaological analyses, Origanum majorona samples were the most safety treatment. For all samples, it has been observed that the microbial load increases slightly during the maintenance period. Sensory evaluation also dedicted that Origanum majorona samples had the best sensorial properties and general accaptibility. As a result, while the increases in microbial load was not observed much compared to a product that is vacuum packed and stored in room conditions, the chemical contents of the products were generally preserved. Considering these results, the turkey jerky is an alternative healthy snack

Determination of co-seismic deformation with GNSS measurements after (Mw=6.0, 08.08.2019) Bozkurt (Denizli) earthquake

08.08.2019 tarihinde, Denizli iline bağlı Bozkurt ilçesinde Mw:6.0 (AFAD) büyüklüğünde bir deprem meydana gelmiştir. 8 km derinde meydana gelen depremin dış merkezi, yaklaşık 50 km uzunluğundaki KD-GB uzanımlı Acıgöl Grabeni üzerinde yer almaktadır. Depreme ait ana şok ve artçı sarsıntıların dağılımları, derinlik ve odak mekanizma çözümleri gibi sismolojik veriler ile bölgenin aktif tektonik yapısı ve diri fay karakteristikleri beraber değerlendirildiğinde, depreme kaynaklık eden fayın, grabenin güneydoğu kenarını sınırlayan DKD-BGB uzanımlı ve kuzeybatıya eğimli Gemiş Fayı olduğu gözlenmektedir. Bu çalışmada, bölgede yer alan sürekli ve kampanya tipi noktalardan oluşan 21 noktalı GNSS ağında gerçekleştirilen geçmiş yıllardaki ölçülerle (deprem öncesi) bölgenin hız alanı belirlenmiş ve elde edilen hız alanı yardımıyla iki boyutlu gerinim analizi yapılmıştır. Gerinim analizinde en büyük gerinimin deprem merkez üssüne en yakın noktada olduğu ve gerinim ile deprem çözümlerinin uyum içinde olduğu görülmüştür. Geçmiş yıllardaki ölçüler (deprem öncesi) ve 2019 yılı (deprem sonrası) ölçüleri kullanılarak, ko-sismik deformasyonlar (yüzey yer değiştirmeleri) belirlenmiştir. Deprem sonrası bölgede meydana gelen deformasyonların kuzey bileşenleri için -7.3 ile 7.5 mm arasında değişim gösterirken, doğu bileşenleri için -4.6 ile 11.6 mm arasında değişim göstermektedir.An earthquake of Mw: 6.0 (AFAD) occurred on 08.08.2019 in Bozkurt district of Denizli province. The hypocenter of the which has depth of 8 km earthquake is located on the NE-SW trending and approximately 50 km long Acıgöl Graben. When the seismological data are evaluated, such as the distribution of the main shock and aftershocks belonging to the earthquake, depth and focal mechanism solutions and the region of active tectonic structure and faults, it is observed was caused of the earthquake by Gemiş fault which is ENE-WSW trending and northwest dipping is bounded southeast edge of Acıgöl graben. In this study, the velocity field of the region was determined by a GNSS network which is consisting of 21 sites and was performed GNSS measurements in the previous years (before the earthquake). With the help of the obtained velocities, it was performed two-dimensional strain analysis. When the strain analysis is examined, it was seen that the largest strain accumulation was at the closest sites to the earthquake epicenter and the strain field and earthquake solutions were in harmony. Using the GNSS measurements performed in the previous years (before the earthquake) and measurements in 2019, the coseismic deformations (surface displacements) were calculated. When the displacements occurred after the earthquake were examined, it was seen that vary between -7.3 and 7.5 mm for the north, it varies between -4.6 and 11.6 mm for the east

Türkiye'deki Katı Atık Deponi Alanlarında Oluşan Gazın Çevresel ve Ekonomik Açıdan İncelenmesi

Due to the rapid population growth, urbanization and technological improvements in our century, waste generation is increasing significantly. In order to prevent harmful environmental effects of these waste, suitable methods should be applied in compliance with relevant regulations. In this respect, sanitary landfilling is the most commonly applied controlling method both in our country and all around the world. During the stabilization of the solid waste collected in landfills, landfill gas with high energy potential accumulates over time with biochemical decomposition of the organic compounds in the waste. Since the energy demand is increasing in the last decades, number of the studies on energy recovery from landfill gas are increasing in all around the world.In addition to harmful environmental impacts, landfill gas has also significant greenhouse gas impact because of high rate of methane content in the composition.Günümüzdeki hızlı nüfus artışı, kentleşme ve teknolojik gelişmeler sonucunda, katı atık miktarlarında önemli oranda artış gözlemlenmektedir.

Axial compression behaviour of concrete-filled auxetic tubular short columns

Concrete-filled steel columns (CFSCs) are of great interest in the literature as they are capable of carrying higher loads by combining the exceptional qualities of steel and concrete. With auxetic materials being introduced to civil engineering applications, the influence of these materials on CFSCs remains a matter of curiosity. The current study implements a nonlinear finite element analysis to evaluate the performance of circular CFSCs with six auxetic tubes under axial compression and the proposed numerical model was validated using published experimental data. The effect of the auxetic steel tube’s porosity and Poisson’s ratio on CFSCs was examined parametrically in terms of ultimate strength using the confined concrete model. Moreover, the stress distributions of the concrete and the auxetic steel tubes were also thoroughly examined. Based on the findings of the analysis, the ultimate load of CFSCs, utilising auxetic tubes with the same density and porosity but different Poisson’s ratio, increased proportionally with the increase of auxetic behaviour. When it comes to auxetic tubes with different densities and porosities, the influence of the Poisson’s ratio of the tubes diminished and the stiffness of tubes became more dominant over the mechanical characteristics of columns as the density of the auxetic steel tubes increased or decreased. The stiffness of the auxetic tubes reduced as porosity increased, as did the ultimate load of the columns. Additionally, the ultimate loads of the auxetic steel tube columns are found to be lower than those of bare steel tube columns filled with concrete due to perforations

Association of GSTM1, GSTT1, GSTP1-ILE105VAL and ACE I/D polymorphisms with ankylosing spondylitis

Ankylosing spondylitis (AS) is a chronic inflammatory disease of unknown origin. The aim of this study is to clarify the relationships between susceptibility and severity of AS and GST-mu1 (GSTM1), GST-theta1 (GSTT1), GST-pi1 (GSTP1)-Ile105Val and angiotensin-converting enzyme (ACE) I/D polymorphisms in AS patients. One hundred thirty-eight AS patients and seventy-one healthy controls were enrolled in this study. Erythrocyte sedimentation rate and C-reactive protein (CRP) levels of the AS patients were recorded. The scores of the numeric rating scale (NRS) pain, the Bath Ankylosing Spondylitis Activity Index, the Bath Ankylosing Spondylitis Metrology Index and the Bath Ankylosing Spondylitis Functional Index were calculated. The genotypes distributions and allele frequencies of GSTM1, GSTT1, GSTP1-Ile105Val and ACE I/D polymorphisms were compared between patients and healthy controls. The Multiplex polymerase chain reaction (PCR) and the PCR-restriction fragment length polymorphism methods were used to detect the polymorphisms of ACE I/D, the GSTT1 and GSTM1 genes and the GSTP1-Ile105Val polymorphism, respectively. There were significantly higher levels of the GSTT1 null and the ACE II genotypes in AS patients compared to those in healthy controls (p = 0.002 and 0.005, respectively). We found significantly higher levels of CRP and the NRS pain scores in the patients with ACE ID or DD genotypes compared to those in the patients with ACE II genotypes (p = 0.005 and 0.035, respectively). The present results showed that genes involved in protection from oxidative stress and ACE gene may influence disease development and course in AS

Prevention of Retrosternal Pericardial Adhesions After Cardiac Surgery With Mitomycin C

Tanyeli, Omer/0000-0001-6275-7744WOS: 000334820200012PubMed: 24252449Background Cross Mark Retrosternal pericardial adhesions may cause significant injuries to the heart and great vessels in cases that require reoperation. Fibroblast proliferation is one of the mechanisms for adhesion formation. Inhibition of fibroblast proliferation is important in reduction of retrosternal adhesions. Mitomycin C (MMC) is able to reduce fibroblast proliferation. We aimed to determine the effect of MMC on prevention of retrosternal pericardial adhesions after primary cardiac operations. Methods Thirty Sprague-Dawley female rats were used in the study. The rats were divided into two groups. First group was control (n = 10) and second group was MMC study group (n = 20). Xiphoid cartilage resection and retrosternal abrasion via subxiphoidal incision was performed. In the study group, MMC (1 mg/kg) was topically applied to the retrosternal space. After 15 days, rats were taken into reoperation and adhesion was graded. Tissue and blood samples were taken before termination procedure. Standard staining procedures and fibroblast growth factor receptor 3 antibody staining, were applied immunohistochemically to tissue samples. Results The average adhesion scores of the control (n = 10) and study (n = 20) (MMC; 1 mg/kg) groups were 2.50 +/- 1.27 and 0.70 +/- 0.86, respectively. The adhesion score of the study group was lower than the control group (p 0.05). Conclusion MMC was found to be effective in the prevention of retrosternal pericardial adhesions without any delay in normal tissue regeneration.Scientific Research Projects Coordinator's Office of our university [1007/0710]This study was funded by the Scientific Research Projects Coordinator's Office of our university (Project No: 1007/0710)
