Over the past decade, a growing number of studies have examined role agricultural export in economic growth Africa. The literature, however, provides conflicting results about export-led hypothesis. In this study, we aim to re-examine impact on by performing meta-analysis. There are two questions interest, namely, (a) whether publication bias is present export-growth literature Africa, and (b) ...

This essay addresses the long-term effectiveness of urban climate change adaptation approaches, based, inter alia, on work in C40 city network. We argue that most cities, dominant framing risk management almost exclusively focuses short-term incrementalities and preventive solutions directly tackling hazards, vulnerability, exposure. approach has serious flaws, leading to missed opportunities f...

Bu çalışma, çelik gömmeli kompozit kolonların, beton dayanımı ile boyuna donatı oranının değişimine göre eksenel basınç kuvveti etkisindeki davranışını açıklamaktadır. sebeple, dört farklı (ϕ16-20-24-30), sınıfı (C40-50-60-70) ve yapısal yüzdesi (%1-2-4-8) için on altı grup olmak üzere toplamda altmış model oluşturulmuştur. Her bir önce Çelik Yapıların Tasarım, Hesap Yapımına Dair Esasları (ÇYT...

The mouse has many advantages over other experimental models for the molecular investigation of left ventricular (LV) function. Accordingly, there is a keen interest in, as well as an intense need for, a conscious, chronically instrumented, freely moving mouse model for the determination of cardiac function. To address this need, we used a telemetry device for repeated measurements of LV functi...

case n > 3. In a related field, that of the natural polyenes, the C40-carotenoids, methods have been used in some laboratories2 for the preparation of stereoisomers, viz., reversible isomerization by refiuxing solutions, by iodine or HCl catalysis, and by melting crystals. Irradiation can also be effective. As the adsorption affinity of stereoisomers varies with the configuration, they can be s...

Recent advances in analytical and sweat collection techniques provide new opportunities to identify noninvasive biomarkers for the study of skin inflammation and repair. This study aims to characterize the lipid mediator profile including oxygenated lipids, endocannabinoids, and ceramides/sphingoid bases in sweat and identify differences in these profiles between sweat collected from nonlesiona...

Terpenoids and steroids constitute the largest known group of plant secondary metabolites. The different groups of terpenes are formed from isoprene (C5) units in enzymatic reactions. Head-to-tail condensation of isoprene units results in the formation of monoterpenes (C10), sesquiterpenes (C15), diterpenes (C20), sesterpenes (C25) and polyterpenes. Tail-to-tail coupling of C15 and C20 units le...

Ten Do It Better, Do They? An Empirical Analysis of an Old Football Myth In this paper we investigate how the expulsion of a player influences the outcome of a football match. Common sense implies a negative impact for the affected team. However, an old football myth suggests that such an expulsion might also be beneficial since it increases the team spirit as well as the efforts of the affecte...

Rice is a model plant species for the study of cellulose biosynthesis. We isolated a mutant, S1-24, from ethyl methanesulfonate (EMS)-treated plants of the japonica rice cultivar, Nipponbare. The mutant exhibited brittle culms and other pleiotropic phenotypes such as dwarfism and partial sterility. The brittle culms resulted from reduced mechanical strength due to a defect in thickening of the ...

We have compared different spectral methods (the standard windowed Fourier transform, the multitaper method (MTM), and the maximum entropy method (MEM)) to determine the coherence between Bouguer gravity and topography and estimate the variations of the effective elastic thickness (Te) of the lithosphere. These methods differ significantly in spatial resolution (1000 to 2000 km) determined by t...
