Doviz Kuru Oynakliginin Ithalata Etkileri: Turkiye Ornegi

The factors affecting the foreign trade have always interested the researchers. In comparison to the other factors, the effects of exchange rate on international trade are a variable that remains at the forefront. Therefore, the influence of exchange rate fluctuation on export and import has been a research subject of a good number of empirical studies. Although consistent results could not been found in many of them, explaining and contributing findings were obtained. In this study, we prove the exchange rate volatility by using MSARCH which is a new econometric method. Moreover, after regrating the import to exchange-rate uncertainty, it is found that the import and exchange rate volatility are inversely relatedExchange Rate Volatility, Imports, Time Series, Uncertainty, Nonlinear Models, Turkish Economy, Risk of Exchange Rate, Markov Switching ARCH (SWARCH)

SOME OF KEY GOODS FOR SUSTAINABLE IMPORTS OF TURKEY FROM ROMANIA

The relationships between Turkey and Romania improve greatly every year. Turkey’s import is about 200 billion USD and it is the biggest partner of EU. The trade between Europe and Turkey is rising every year about 10%. Therefore the import rate has to increase more between the two countries. Some main products imported from Romania are Vehicles, Iron or steel products, Oil Electronic equipment, Perfumes, cosmetic and Rubber. However Romania has a big potential of export to Turkey. For example Romania has produced medical and pharmaceutical products, construction paints and plastic products. These products are imported more often from Turkey. Turkey balances between import and export but every year export increases. Consequently, the rate of export is more rapid than that of import. We analyze the trade between Turkey and Romania by tables and charts; we propose that Turkey improves import from Romania per year at almost 15%. When transportation is getting better, the diversity of goods imported from Romania rises. We obtain that Romania has big fortunate to become a big trade partner of Turkey. Because Romania industry is enough to manufacture the goods whatever required from Turkey

Determination of Serum Adenosine Deaminase and Xanthine Oxidase Levels in Patients with Crimean–Congo Hemorrhagic Fever

OBJECTIVE: Crimean-Congo hemorrhagic fever is an acute viral hemorrhagic fever with a high mortality rate. Despite increasing knowledge about hemorrhagic fever viruses, little is known about the pathogenesis of Crimean-Congo hemorrhagic fever. In this study, we measured serum adenosine deaminase and xanthine oxidase levels in Crimean-Congo hemorrhagic fever patients. METHODS: Serum adenosine deaminase levels were measured with a sensitive colorimetric method described by Giusti and xanthine oxidase levels by the method of Worthington in 30 consecutive hospitalized patients (mean age 42.6 ± 21.0). Laboratory tests confirmed their diagnoses of Crimean-Congo hemorrhagic fever. Thirty-five subjects (mean age 42.9 ± 19.1) served as the control group. RESULTS: There was a significant difference in adenosine deaminase and xanthine oxidase levels between cases and controls (p<0.05). However, neither adenosine deaminase nor xanthine oxidase levels varied with the severity of disease in the cases assessed (p>0.05). CONCLUSION: Adenosine deaminase and xanthine oxidase levels were increased in patients with Crimean-Congo hemorrhagic fever. Elevated serum xanthine oxidase activity in patients with Crimean-Congo hemorrhagic fever may be associated with reactive oxygen species generated by the xanthine/xanthine oxidase system during inflammatory responses. In addition, elevated lipid peroxidation may contribute to cell damage and hemorrhage. The association of cell damage and hemorrhage with xanthine oxidase activity should be further investigated in large-scale studies

Melting of PCM in a thermal energy storage unit: Numerical investigation and effect of nanoparticle enhancement

The present paper describes the analysis of the melting process in a single vertical shell-and-tube latent heat thermal energy storage (LHTES), unit and it is directed at understanding the thermal performance of the system. The study is realized using a computational fluid-dynamic (CFD) model that takes into account of the phase-change phenomenon by means of the enthalpy method. Fluid flow is fully resolved in the liquid phase-change material (PCM) in order to elucidate the role of natural convection. The unsteady evolution of the melting front and the velocity and temperature fields is detailed. Temperature profiles are analyzed and compared with experimental data available in the literature. Other relevant quantities are also monitored, including energy stored and heat flux exchanged between PCM and HTF. The results demonstrate that natural convection within PCM and inlet HTF temperature significantly affects the phase-change process. Thermal enhancement through the dispersion of highly conductive nanoparticles in the base PCM is considered in the second part of the paper. Thermal behavior of the LHTES unit charged with nano-enhanced PCM is numerically analyzed and compared with the original system configuration. Due to increase of thermal conductivity, augmented thermal performance is observed: melting time is reduced of 15% when nano-enhanced PCM with particle volume fraction of 4% is adopted. Similar improvements of the heat transfer rate are also detecte

KONYA ŞEHRİ TAŞIT TRAFİĞİ GÜRÜLTÜ SEVİYELERİ HARİTASININ GIS VE GPS TEKNOLOJİLERİ KULLANILARAK ELDE EDİLMESİ

Traffic noise has important share in overall noise pollution in residential areas. Traffic noise is caused by vehicles on roads and railway. Air traffic also causes considerable noise. Noise levels due to the traffic on roads could exceed admissible levels especially in densely populated residential areas. In this study, vehicle traffic noises were measured at 90 different measurement points determined on main streets, where mass of traffic flow is present, in the morning hours between 07.30 and 08.30 and noon hours between 12.00 and 13.30 and evening hours between 17.00 and 18.30. In addition, 30 m and 60 m away from streets noise levels at points were also measured. Thus, noise level changes as going away from streets were determined. Obtained spatial and noise values at the points by Magellan GPS receiver and CEL 368 noise measurement device, respectively were then entered GIS environment by using ArcView GIS software to represent distribution of noise levels along Konya’s streets. A digital platform was established regarding spatial data and noise levels. As a result of this work traffic noise levels maps of Konya were established at the investigated streets.Trafikten kaynaklanan gürültü kirliliği, günümüzde yerleşim bölgelerinde oluşan gürültü kirliliği içerisinde önemli bir paya sahiptir. Trafik gürültüsü kara, demiryolu ve hava trafiğinden kaynaklanan gürültüdür ve özellikle karayolu taşımacılığının, ulaşımın ve kentleşmenin yoğun olduğu bölgelerde karayolu gürültüsü gürültü kontrol yönetmeliğinde belirtilen sınırların üzerine çıkabilmektedir. Bu çalışmada Konya’da trafiğin yoğun olduğu ana caddeler üzerinde belirlenen yaklaşık 90 farklı noktada 07.30-08.30, 12.00-13.30 ve 17.00-18.30 saatleri arasında hafta içerisinde oluşan gürültü ölçümleri yapılmıştır. Ayrıca cadde üzerindeki noktalardan iç kısımlara 30 metre ve 60 metre daha girilerek bu noktalardaki gürültü ölçümleri yapılmış ve caddeden uzaklaştıkça gürültü düzeyindeki değişim incelenmiştir. Çalışmada gürültü düzeylerinin ölçüldüğü noktalara ait konumsal verilerin toplanmasında Magellan marka düşük maliyetli bir el GPS (Küresel konum belirleme sistemi) alıcısı kullanılmış ve elde edilen öznitelik (gürültü) verileri ile GPS aracılığıyla üretilen konum bilgileri ArcView yazılımı kullanılarak ilişkilendirilerek GIS (Coğrafik bilgi sistemi-CBS) ortamına aktarılmıştır. Bu sayede konumsal verilerle ilişkilendirilmiş gürültü verileri üzerinde her türlü analizin yapılabileceği sayısal bir platform oluşturulmuştur. Bu çalışmanın bir sonucu olarak da Konya şehri taşıt trafiği gürültü seviye haritaları ölçüm yapılan güzergahlar için üretilmiştir

Is the association between mothers’ autistic traits and childhood autistic traits moderated by maternal pre-pregnancy body mass index?

Background: Previous studies showed that there is a positive association between mothers’ and children’s autistic traits. We also tested if this association is more pronounced in mothers with a higher pre-pregnancy body mass index (BMI). Method: The study was embedded in two cohorts with information available for 4,659 participants from the Generation R and for 179 participants from the Cambridge Ultrasound Siblings and Parents Project (CUSP) cohort. In both cohorts, maternal autistic traits were assessed using the short form of the Autism Spectrum Quotient, and information about maternal height and weight before pregnancy was obtained by questionnaire. Child autistic traits were assessed with the short form of Social Responsiveness Scale in Generation R (M = 13.5 years) and with the Quantitative Checklist for Autism in Toddlers (Q-CHAT) in the CUSP cohort (M = 1.6 years). Result: Higher maternal autistic traits were associated with higher autistic traits in toddlerhood (CUSP cohort; βadjusted = 0.20, p &lt; 0.01), in early childhood (Generation R; βadjusted = 0.19, p &lt; 0.01), and in early adolescence (Generation R; βadjusted = 0.16, p &lt; 0.01). Furthermore, a higher maternal pre-pregnancy BMI was associated with higher child autistic traits, but only in Generation R (βadjusted = 0.03, p &lt; 0.01). There was no significant moderating effect of maternal pre-pregnancy BMI on the association between autistic traits of mothers and children, neither in Generation R nor in CUSP. In addition, child autistic traits scores were significantly higher in mothers who were underweight and in mothers who were overweight compared to mothers with a healthy weight. Conclusion: We confirm the association between maternal and child autistic traits in toddlerhood, early childhood, and early adolescence. Potential interacting neurobiological processes remain to be confirmed.</p
