We analyze two and three-dimensional variants of Hotelling’s model of differentiated products. In our setup, consumers can place different importance on each product attribute; this is measured by a weight in the disutility of distance in each dimension. Two firms play a two-stage game; they choose locations in stage 1 and prices in stage 2. We seek subgame-perfect equilibria. We find that all ...

D (Dairy Herd Improvement Association) records are an essential part of dairy herd management for many progressive dairy operations. The old adage “If you can’t measure it, you can’t manage it” holds true when it comes to dairy farm management, particularly when it comes to somatic cell count (SCC) management. When working with dairy farmers, we often hear the statement “I don’t know how I woul...

Introduction: β-carbolines are shown to have significant anti-inflammatory effect via the inhibition of some inflammatory mediators including TNF-α and PGE2. In previous studies Purkinje cell deterioration have been proposed the dominant pathogenesis of harmaline toxicity. WIN55, 212-2 is a non-selective cannabinoid CB1 and CB2 receptor agonist. Combination of WIN55, 212-2 ...

The effect of chronic exposure (35 days) to sub-lethal concentrations of copper (17-212 ppb) and zinc (41-525 ppb) on growth of Farfantepenaeus paulensis postlarvae 17 days old (PL(17)) was analysed. The effects of acute exposure of PL(17) to the same metal on food ingestion and oxygen consumption were also evaluated. Studies were performed using copper and zinc singly, and in a mixture of equi...

The need for more effective anti-chlamydial therapeutics has sparked research efforts geared toward further understanding chlamydial pathogenesis mechanisms. Recent studies have implicated the secreted chlamydial serine protease, chlamydial protease-like activity factor (CPAF) as potentially important for chlamydial pathogenesis. By mechanisms that remain to be elucidated, CPAF is directed to a...

OBJECTIVE Although tuberculous lymphadenitis and Kikuchi disease are common causes of cervical lymphadenopathy in Asians and exhibit similar clinical manifestations, their treatment strategies are totally different. The purpose of this study was to identify ultrasonographic features that distinguish these two diseases. MATERIALS AND METHODS This study was approved by the Institutional Review ...

Bu çalışmada, kromit zenginleştirilmesinde nihai artık olarak elde edilen bir olivin numunesindeki demir içeriğinin manyetik ayırma yöntemleri ile azaltılabilme potansiyeli incelenmiştir. kapsamda, öncelikle numune +212, -212+150 ve -150 µm üç fraksiyona ayrılmıştır. Sonrasında iri boyutlara kuru, ince boyuta ise yaş uygulanmıştır. Sonuçlar olmayan fraksiyonun ağırlık yüzdesi, Fe2O3 içeriği gid...

Findings of coesite and microdiamond in metamorphic rocks of supracrustal protolith led to the recognition of continental subduction to mantle depths. The crust-mantle interaction is expected to take place during subduction of the continental crust beneath the subcontinental lithospheric mantle wedge. This is recorded by postcollisional mafic igneous rocks in the Dabie-Sulu orogenic belt and it...
