in the present paper, the biodesulfurization of simulated light fuel oil (i.e., dibenzothiophene (dbt) in dodecane) and untreated kerosene with a high total sulfur content has been studied by a native isolated bacterium named bacillus cereus hn. the influences of various parameters such as the reaction temperature (t), biocatalyst cell density, oil phase fraction (ofp), and initial dbt concentr...

Scholars have been investigating the quick emergence of digital platforms, essentially through the lens of digital native firms. If there is limited occurrence of platforms launched by incumbent firms such as Daimler (Car2Go, Moovel) or Johnson Controls (Panopix), the economics of their strategic responses through platforms by incumbents merit attention. This paper provides the first largescale...

Protease activities in human ileal effluent and feces were compared by using a variety of native and diazotized protein substrates. In many cases the diazotized proteins had altered susceptibilities to hydrolysis compared with the native proteins. Proteolytic activity was significantly greater than (P less than 0.001) in small intestinal effluent than in feces (319 +/- 45 and 11 +/- 6 mg of azo...

Endophytic bacteria associated with the fern Dicksonia sellowiana were investigated. The bacterial communities from the surface-sterilized pinnae and rachis segments of the plants from the Brazilian Atlantic Rainforest that grew in native field conditions were compared with the bacterial communities from plants grown in greenhouses and plants that were initially grown in greenhouses and then tr...

The use of game elements in non-game contexts (gamification) -has previously been widely explored in contexts such as healthcare and marketing but less extensively in education and training. In this paper we explore the use of gamification in education and training. Traditional training methods often fail to engage or motivate students, especially Digital Natives raised from a young age with ap...

BACKGROUND Epidemiologic studies have suggested that most cases of sporadic colon cancer can be attributed to diet. The recognition that colonic microbiota have a major influence on colonic health suggests that they might mediate colonic carcinogenesis. OBJECTIVE To examine the hypothesis that the influence of diet on colon cancer risk is mediated by the microbiota through their metabolites, ...

Surfactant protein B (SP-B) is secreted into the airspaces with surfactant phospholipids where it reduces surface tension and prevents alveolar collapse at end expiration. SP-B is a member of the saposin-like family of proteins, several of which have antimicrobial properties. SP-B lyses negatively charged liposomes and was previously reported to inhibit the growth of Escherichia coli in vitro; ...
