in this work, reactive absorption of gases in aqueous electrolyte solutions has been investigated resulting in the development of a procedure in order to calculate the concentrations of ionic and molecular species in the liquid phase. two duplicate experiments were conducted to investigate simultaneous reactive absorption of ammonia and carbon dioxide in partially carbonated ammonia solutions. ...

the geometry of a collector is one of the important factors that can increase the incident radiation on the collector surface. in the present study, the incident radiation for a stationary collector with cone geometry, i.e. a conical collector, is theoretically and experimentally investigated. this type of collector is always stable and does not need a fixture to install. moreover, it has a sym...

This study investigated the effects of high temperature exposure on the compressive, tensile, and flexural strengths of concrete containing glass fiber. A total of 108 cubic specimens (150 mm × 150 mm × 150 mm), cylindrical specimens (300 mm × 150 mm), and prismatic specimens (500 mm × 150 mm × 150 mm) were prepared for compressive, tensile, and flexural strength testing, respectively. The spec...

In the past centuries, water was considered as one of the most important factors to appear the social groups and develop communities. Today, it is emphasized as a necessity to supply the economic and political balance. Regarding to limited water resources and underused plains in the world, to provide the humans needs and prevent to appear the consequences of water shortage, the best strategy is...

the shape of a solar collector is an important factor in solar-to-thermal energy conversion. conical shape is one of the stationary and symmetric shapes that can be employed as a solar water heater. flow rate of working fluid on the solar collector has an important effect on the efficiency of the collector. the present study is an experimentally investigated of the performance of the solar coni...

Myopic loss aversion (MLA) has been established as one prominent explanation for the equity premium puzzle. In this paper we address two issues related to the effects of MLA on risky investment decisions. First, we assess the relative impact of feedback frequency and investment flexibility (via the investment horizon) on risky investments. Second, given that we observe higher investments with a...

What causes a government to adopt a new program or policy? Despite a large number of empirical studies available to date, the relative importance of various determinants remains obscure because of difficulties of statistical identification. We present an experimental setting to study the diffusion of policy innovations in the laboratory. Our approach discriminates between experimentation, exper...

This study experimentally tested whether a stressor characterized by social-evaluative threat (SET), a context in which the self can be judged negatively by others, would elicit increases in proinflammatory cytokine activity and alter the regulation of this response. This hypothesis was derived in part from research on immunological responses to social threat in nonhuman animals. Healthy female...

Incentives, Decision Frames, and Motivation Crowding Out – An Experimental Investigation A simple principal agent problem is experimentally investigated in which a principal repeatedly sets a wage and an agent responds by choosing an effort level. The principal's payoff is determined by the agent's effort. In a first setting the principal can only set a fixed wage in each period. In a second se...
