a set of multicomponent perovskite oxide nanoparticles based on la1-xsrxco1-yfeyo3-δ(lscf) were prepared by a simple chemical precipitation method for application in low temperature solid oxide fuel cells (lt-sofc) as cathode materials.  the precursor materials used in this synthesis were lanthanum nitrate hexahydrate [la(no3)3.6h2o], strontium nitrate [sr(no3)2], cobalt nitrate hexahydrate [co...

In the current climate change scenario, natural spring in region is drying or vanishing, increasing water scarcity. So, to protect this vital resource, rejuvenation and protection activities are needed. Thus, potential zones (SPZ) must be identified execute project successfully. The study used remote sensing (RS) geographical information system (GIS) techniques determine an SPZ based on multicr...

This study investigated ferromanganese oxide (Fe-Mn oxide) precipitated on porifera located the tabletop of Magellan seamount (OSM17, 1571 m depth) in western Pacific. As growth rate Fe-Mn is several mm/Myr and skeletons are difficult to preserve posthumously, geochemical mineralogical studies have not yet been conducted this topic. oxides from a morphological differentiation general deposits b...

A comprehensive study was intended to show the microstructural features of additively manufactured (AM) 18Ni-300 maraging steel. Uniaxial tensile tests were conducted on specimens built using laser powder bed fusion (LPBF) technique for two different layer thicknesses. The have lowest possible porosity, and showed stages strain hardening. In stage I, dislocation density increased, leading a pos...

This paper presents a search algorithm for estimating posterior probabilities in discrete Bayesian networks. It shows how conflicts (as used in consistency-based diagnosis) can be adapted to speed up the search. This algorithm is especially suited to the case where there are skewed distributions, although nothing about the algorithm or the definitions depends on skewness of distributions. The g...

Bee keeping is indispensable to global food production. It is an alternate income source, especially in rural underdeveloped African settlements, and an important forest conservation incentive. However, dwindling honeybee colonies around the world are attributed to pests and diseases whose spatial distribution and influences are not well established. In this study, we used remotely sensed data ...

Sensing actions are important for planning with incomplete information. A solution for the frame problem for sensing actions was proposed by Scherl and Levesque. They adapt the possible world model of knowledge to situation calculus. In this paper we propose a high level language in the spirit of the language A, that allows sensing actions. We then present two approximation semantics of this la...

The edentulous mandible fractures are rare representing less then 5% in the majority of series. Their treatment represents nevertheless a challenge. The bone atrophy that happens in this situation is related with the higher incidence of treatment complications demanding some special attention to the therapeutic options. In contrast with the dentulous mandibles, tension and compression zones are...

In this work, it is shown that variations in the ratio of oxygen to zinc precursors at constant temperature allow changing the surface morphology of zinc oxide (ZnO) films deposited by lowpressure metalorganic chemical vapor deposition, while keeping the sheet resistance and transparency of the layers constant. This allows developing ZnO layers combining interesting properties such as low surfa...
