introduction: safety climate received substantial attention due to its potential for explaining variation in safety-related outcomes. the present study examined degree of safety climate related to fatalism and perceived helplessness among workers’ isfahan steel company. materials and methods: the current study was a correlation study. sample consisting of 189 employees in isfahan steel company ...

in biaxially strained p-mosfet with si channel, formation of a parasitic parallel channel due to misalignment of energy bands degrades device performance by increasing off-state current. in this paper a new approach has been introduced to eliminate this parasitic channel by increasing the dopant concentration of virtual substrate up to . using simulation the impact of this method on the parasit...

An analysis of the climate parametrization scheme adopted by conventional forest gap models revealed that most models assume a constant climate and are difficult to calibrate consistently. Tree growth showed unrealistically sensitive threshold effects along ecological gradients of temperature and precipitation. A new parametrization was compared with its predecessors in terms of the model's cap...

the present study mainly aims to demonstrate the weaknesses and strengths of using marketing principles in academic libraries and finally presenting some important suggestions in order to improve their marketing. this study proceeds through expressing the current marketing situation of studied academic libraries from the view point of 4p model. in this regard, the current situation is analyzed ...

Fire is the major stand-renewing disturbance in the circumboreal forest. Weather and climate are the most important factors influencing fire activity and these factors are changing due to human-caused climate change. This paper discusses and synthesises the current state of fire and climate change research and the potential direction for future studies on fire and climate change. In the future,...

Projections of future climatic changes are a key input to the design of climate change mitigation and adaptation strategies. Current climate change projections are deeply uncertain. This uncertainty stems from several factors, including parametric and structural uncertainties. One common approach to characterize and, if possible, reduce these uncertainties is to confront (calibrate in a broad s...
