Newcastle disease virus (NDV)-induced membrane fusion requires formation of a complex between the hemagglutinin-neuraminidase (HN) and fusion (F) proteins. Substitutions for NDV HN stalk residues A89, L90, and L94 block fusion by modulating formation of the HN-F complex. Here, we demonstrate that a nearby L97A substitution, though previously shown to block fusion, allows efficient HN-F complex ...
We explore the relation between the establishment of a regulatory agency and the performance of the electricity sector. We exploit a dataset comprising firmlevel information on a representative sample of 220 electric utilities from 51 development countries for the period 1985 to 2005. Our results indicate that regulatory agencies are associated with more efficient firms and with higher social w...
This review paper provides an overview of the application of behavioral public economics to energy efficiency. I document policymakers’ arguments for “paternalistic” energy efficiency policies, formalize with a simple model of misoptimizing consumers, review and critique empirical evidence, and suggest future research directions. While empirical results suggest that policies to address imperfec...
We propose a difference-in-differences (DiD) approach to estimate the impact of incentives on cost reduction. We show theoretically, and estimate empirically, that German electricity distribution system operators (DSOs) incur higher costs when subject to a loweredpowered regulation mechanism. The difference is particularly significant (about 7%) for firms in the upper quartile of the efficiency...
Cultivated barley, Hordeum vulgare L., is considered to be a nonhost or intermediate host species for the wheat leaf rust fungus Puccinia triticina. Here, we have investigated, at the microscopic and molecular levels, the reaction of barley cultivars to wheat leaf rust infection. In the nonhost resistant cultivar Cebada Capa, abortion of fungal growth occurred at both pre- and posthaustorial st...
The objective of the study was to investigate the screening utility of a questionnaire for cerebral visual impairment (CVI) by correlating the questionnaire with diagnostic tools such as the L94, the Test of Visual Perceptual Skills - Revised and the Visual Perception subtask of the Beery test of VisuoMotor Integration.The questionnaire consisted of 46 items, exploring different characteristics...
امروزه برنامهریزی توسعه همزمان شبکههای برق و گاز بهعنوان روشی برای حداقلسازی هزینههای سرمایهگذاری مورد توجه قرار گرفته است. در این تحقیق انواع روشهای توسعه شبکههای برق و گاز در یک مطالعه واقعی در استان خراسان مورد بررسی قرار گرفته است. براساس یافتههای تحقیق که در دو روش توسعه یکپارچه و نیز توسعه به روش ADMM که در آن یک نهاد واسط، وظیفه هماهنگی دو شبکه برق و گاز را برعهده دارد نتایج یک...
This study aims to find the existence of a long-term relationship between subsidized energy, population, inflation, economic growth, and consumption electrical energy in Indonesia for period 1987-2018. In order analyse long run relationship, this research was conducted using Autoregressive Distributed Lag (ARDL) model. focused on subsidy, considering that is one four countries still apply energ...
The coagulation cofactor Va (FVa) is a noncovalent heterodimer consisting of a heavy chain (FVaH) and a light chain (FVaL). Previously, the fibrinolytic effector plasmin (Pn) has been shown to inhibit FVa function. To understand this mechanism, the fragmentation profile of human FVa by Pn and the noncovalent association of the derived fragments were determined in the presence of Ca(2+) using an...
