Large numbers of trace elements occur in coals used for coal power plants combustion. In order to assess the environmental impact fuel cycle, and ash samples need be analyzed a number toxic radioactive elements. Six from Ridi-Awe Lafia (Nasarawa State), Garin Maiganga (Gombe state) Nigeria deposit were collected. The subjected gross calorific value determination, X-ray diffraction spectrometry,...

The potential of airfoil optimisation for the specific requirements airborne wind energy (AWE) systems is investigated. Experimental and numerical investigations were conducted at high Reynolds numbers S1223 an optimised with thin slat. geometry was generated using NSGA-II algorithm in conjunction 2D-RANS simulations. results showed that simultaneous slat most promising approach. Furthermore, c...

This paper identifies and analyses a new effect related to the cyclical behaviour of labour supply: Entitled-Worker Effect (EWE). is different from well-known Added-Worker (AWE) Discouraged-Worker (DWE). The EWE consequence one most important institutions: unemployment benefit (UB). We develop model with uncertainty about results job-seeking transaction costs linked such search process, showing...

Abstract Introduction One experiences admiration and respect when acknowledging excellence in others. Admiration relates to the person’s superior abilities, whereas focuses on person as a whole. Although previous studies suggest link between admiration/respect motivation, it is unclear whether these emotions enhance task performance. We investigated relationship Method Forty-two Japanese partic...

This paper fortifies and defends the so called Sufficiency Argument (SA) against Classical Invariantism. In Sect. 2, I explain the version of the SA formulated but then rejected by Brown (2008a). In Sect. 3, I show how cases described by Hawthorne (2004), Brown (2008b), and Lackey (forthcoming) threaten to undermine one or the other of the SA’s least secure premises. In Sect. 4, I buttress one ...

Considering the widespread use of alkaline water electrolysis (AWE) in chemical industry and growing need to design manufacture low-cost efficient electrodes, optimization a Ni-Mo-coated stainless steel substrate is investigated present work this as cathode an electrolyzer. The crystallographic structure, surface morphology, composition optimized coating are characterized by X-ray diffraction a...

This paper proposes and simulates vertical airborne wind energy (AWE) farms based on multi-aircraft systems with high power density (PD) per ground area. These consist of many independently located that are flying at the same inclination angle, but different tether lengths, such all aircraft fly in a large planar elliptical area is to tethers. The individual assigned non-overlapping flight cyli...

Abstract This article discusses how the term ‘curiosity’ emerged as a leading element in development of action performance research project Microgravity . The focus is on effect curiosity an activator movement participatory which participants are invited to explore new bodily conditions for first time (in this case, reduced gravity through vertical dance technique). I begin with account what is...
