Wireless optical is categorized as a last mile solution for the sake of complementing the Gigabits network solution. Recently, multi-channels wireless optical (WO) has been introduced to increase the coverage and the link range up to kilometers and reduce other possible losses. This paper proposed a multi-channels ellipsoid structure by analyzing a transmission distance by incorporating the num...

Three strains of Legionella feeleii from patients with pneumonia (425-MI-H, 691-WI-H, and 693-WI-H) and one environmental strain (713-MI-E) received at the Centers for Disease Control for reference diagnostic testing were compared with the type strain WO-44C-C3 (ATCC 35072) by DNA hybridization, chemical analysis of cellular fatty acids and ubiquinones, biochemical tests, and serological charac...

First principles calculations through density functional theory (DFT)+$U$ method were performed to assess the effect of Li interstitial doping on optoelectronic properties NiO and cubic, hexagonal, monoclinic WO$_3$. The implications structural electronic their relationship with optical properties, such as dielectric response absorption coefficient in context electrochromism, are discussed. (i....

Abstract Zwar ist die nationalsozialistische Judenverfolgung wiederholt als Geschichte des Raubs beschrieben worden, jedoch sind konkreten Praktiken der Zwangsarbeitswirtschaft bislang nur ansatzweise erforscht. Frank Grelka geht davon aus, dass Arbeits- und Finanzpolitik Regierung Generalgouvernements keiner ökonomischen Rationalität folgte, sondern sie am Beginn Holocaust in Polen stand. Dazu...

Abstract Die Reinhaltung von Fertigungsanlagen spielt in Lebensmittel‐ und Chemieindustrie eine besonders große Rolle. Zwar sind vielerorts automatische Absauganlagen den Prozess integriert, doch die manuelle Reinigung mit Industriesaugern ist vielen Fällen zusätzlich erforderlich. Störstoffe können das Produktionsumfeld geraten gravierende Probleme nach sich ziehen. Ob Hersteller oder Reinigun...

Tungsten trioxide nanoparticles with two different sizes (average particle sizes about 50 and 80 nm) were prepared by the spray pyrolysis method. Photo degradation of Congo Red (azo dye) showed that photo catalytic property of the as-prepared WO3 nanoparticles with average size about 80 nm is higher than the sample with average size about 50 nm. Photo degradation of Rhodamine B (...

Abstract Glasses belonging to the x WO 3 -(30- ) Bi 2 O –15Li O–15CaO–40B (0 ≤ 10) have been obtained by melt-quenching technique. With increasing concentration of , an increase in measured glass transition temperature $${T}_{\mathrm{g}}$$ T g and crystallization $${T}_...
