24 Kasım 2015’de Rus uçağımın düşürülmesi, Türkiye ve Rusya arasında politik kriz yaratmış ekonomik yaptırımlarla sonuçlanmıştır. Bu çalışmada, 15 Temmuz 2016 darbe kalkışması ile sonlanan bu problemli dönemin, Borsa İstanbul’un yaşanan eko-politik sorunlardan etkilenen sektörlerimizin ulusal uluslararası sistematik risk düzeyine etkileri araştırılmıştır. Haziran 2012-Haziran 2019 dönemi piyasa...

Portable negative air ion generator has been designed and tested. This device generates continuous emission of unipolar (negative) ions and it was evaluated by investigating its ability to remove respirable particles such as different smoke verities (mosquito coil smoke, cigarette smoke, petrol smoke) from indoor air environment. The experiment was carried out in closed glass container, decay r...

The Energy Tax Directive recently proposed by the European Commission envisages to tax fuels based on their energy content. By raising prices for diesel to a level higher than that of petrol, this proposal would eliminate the price advantage currently enjoyed by diesel in most EU Member States. To explore the implications of such a tax regime for automobile travel, the present analysis undertak...

Soil microbial communities play an important role in the biodegradation of different petroleum derivates, including hydrocarbons. Also other biological factors such as enzyme and respiration activities and microbial abundance are sensitive to contamination with petroleum derivates. The aim of this study was to evaluate the response of autochthonic microbial community and biological parameters (...

In this study, the micronucleus (MN) frequency was assessed as a measure of genotoxicity in exfoliated cells of buccal mucosa extracted from 110 petrol pump workers and 100 controls. For each individual, 3,000 exfoliated buccal cells were analyzed. The individuals used in the study were grouped based on their smoking, drinking alcoholic beverages, and tobacco chewing habits. There was a signifi...

Then, define u(xyz) = 100 ∗ U(x) + 10 ∗ U(y) + U(z), where x ∈ {red, blue, green}, y ∈ {electric, petrol, diesel}, and z ∈ {German, French,UK}. Observe that for all x, x′ ∈ {red, blue, green}with x 6= x′, and y, y′ ∈ {electric, petrol, diesel} with y 6= y′, and z ∈ {German, French,UK} we have that (i) |U(y)− U(y′)| > U(z), and (ii) |U(x)− U(x′)| > U(y) + U(z). Intuitively, this ensures that the...
