conclusions it was the first study that attempted to detect the insertion elements isaba and ic lineages in mdr-ab species isolated from patients with burning in iran. background multidrug resistant strains of acinetobacter baumannii (mdr-ab) have emerged as alarming nosocomial pathogens among patients with burning. objectives the current study aimed to determine the susceptibility of a. bauman...

One of the main concerns to design earth dam is the stability of the upstream slope of the earth dam in phase of rapid drawdown. Confined pore water pressure reduces the effective stress in this mode, so possibility of the instability and slippage will be increased. The main goal of this research is to investigate changes in the pore water pressure by using horizontal drains in upstream slope o...

This paper investigates the determinants of vertical integration and confronts some of the predictions of the leading approach to the internal organization of the firm with data from the UK manufacturing sector. Consistent with the theory, it shows that an upsteam and downstream activity pair are more likely to be vertically integrated, when the downstream (the producer) is more technology inte...

The use of word vector embeddings as the basis for many upstream tasks in text processing has lead to large improvements in accuracy. However, the exact reasons for this success largely remain unclear, as the properties and relations that these embeddings encode are often not well understood. Our goal in this ongoing project is to design effective interactive visualizations that help practition...

We examine vertical backward integration in a reducedform model of successive oligopolies. Our key findings are: (i) There may be asymmetric equilibria where some firms integrate and others remain separated, even if firms are symmetric initially; (ii) Efficient firms are more likely to integrate vertically. As a result, integrated firms also tend to have a large market share. The driving force ...

The paper discusses economic theories of harm for anti-competitive margin squeeze by unregulated and regulated vertically integrated firms. We review both predation and foreclosure theories, as well as the mere exploitation of upstream market power. We show that foreclosure provides an appropriate framework in the case of an unregulated firm, whereas a firm under tight wholesale regulation shou...
