The Environmental Kuznets Curve (EKC) and related approaches to human-environment problems (e.g., Forest Transition Theory) generally posit an inverted U-shaped relationship between environmental degradation and economic development, frequently utilizing a cross-national approach. After numerous years of research, the overall empirical evidence remains equivocal: case studies that appear to sup...

The possibility of the existence of environmental Kuznet curve (EKC) has been debated extensively in the literature. The reality of EKC is that, by pursuing growth in income, environmental objectives can be simultaneously accomplished without initiating extra intervention tools. Various studies have been conducted on the existence of EKC without any consensus. Therefore, in this paper, the auth...

The TOR signaling pathway is crucial in the translation of nutritional inputs into the protein synthesis machinery regulation, allowing animal growth. We recently identified the Bud32 (yeast)/PRPK (human) ortholog in Drosophila, Prpk (p53-related protein kinase), and found that it is required for TOR kinase activity. Bud32/PRPK is an ancient and atypical kinase conserved in evolution from Arche...

In recent years, extensive literature on the Environmental Kuznets Curve leading to optimistic policy conclusions has attracted great attention. However, the underlying cross-section estimations are not very reliable. Accordingly, this contribution uses time series data for a single country with good data quality: Germany. With a specification that includes all theoretical variations and differ...

هدف این مقاله بررسی یک رابطه سیستماتیک میان آلودگی زیست محیطی و توسعه اقتصادی در ایران است. منحنی زیست محیطی کوزنتس(EKC) رابطه‌ای تجربی برای نشان دادن ارتباط میان آلودگی‌های زیست محیطی و درآمد و رشد اقتصادی است. با آزمون فرضیه EKC این پرسش به صورت ضمنی پاسخ داده می‌شود که آیا درآمد سرانه بالا و رشد به کاهش آلودگی منجر می‌شود. این بررسی یکبار با داده‌های سری زمانی(کشور ایران) و بار دیگر با داده‌...

Epidemic keratoconjunctivitis (EKC) is a severe, contagious ocular disease that affects 20 to 40 million individuals worldwide every year. EKC is mainly caused by six types of human adenovirus (HAdV): HAdV-8, -19, -37, -53, -54, and -56. Of these, HAdV-8, -19, and -37 use sialic acid-containing glycans as cellular receptors. αVβ3, αVβ5, and a few additional integrins facilitate entry and endoso...

In this study, based on the Environmental Kuznets Curve (EKC) framework, we empirically examine the effects of trade openness and the level of economic development on pollution emission across the Chinese provinces. Our regression analysis shows that increasing trade openness contributes to higher pollution emission, where the effect of the former may be realized through its impacts on total fa...

The relationship between income and environmental quality is poorly understood at best. We expand the Environmental Kuznets Curve (EKC) literature by considering not only the role of emissions but also the role of the environment’s absorptive capacity in the relationship between income and environmental quality. Building off of a simple conceptual model, we construct two different aggregate mea...

Electrokinetic chromatography (EKC) with poly(sodium undecylenic sulfate) (poly-SUS) is utilized to separate environmental pollutants such as 2-6-ring polycyclic aromatic hydrocarbons (PAHs). Parameters such as pH, concentration of polymeric surfactants, and the use of organic modifiers were investigated to follow the retention trends of PAHs. A baseline separation of all 16 PAHs in about 30 mi...
