The aquatic environment is the habitat of many microorganisms, including Plesiomonas shigelloides and Aeromonas species which are pathogenic to human and animals. In the present investigation, we evaluated the occurrence of these pathogens from marine mammals beached or accidentally captured by fishing net in southeastern (RJ) and southern (RS) coastal Brazilian regions. A total of 198 swabs fr...

Most automotive plastic waste (APW) is landfilled or used in energy recovery as it unsuitable for high-quality product mechanical recycling. Chemical recycling via pyrolysis offers a pathway toward closing the material loop by handling this heterogeneous and providing feedstock producing virgin plastics. This study compares chemical scenarios APW regarding climate change impact cumulative deman...

The energy independent model pseudopotential (EIMP) formalism, developed in the preceding paper, and Shaw’s optimized model potential (OMP) formalism are applied to first principles calculations of phonon spectra of the alkali metals and AI and of Fermi surface distortions for the alkali metals. Then the applicability of the EIMP formalism for calculating actual physical quantities needed to ch...

BACKGROUND Detection, confirmation and monitoring of cholera outbreaks in many developing countries including Uganda is a big challenge due to lack of the required resources and the time the test takes. Culture method which takes 24-48 h to get the feedback and requires highly skilled laboratory staff plus other complex resources is the standard test. This study evaluated the new cholera rapid ...

background: old methods of administrating can't cover the rapid changes of today. these changes redounded new organizations like learning organizations to be formed. the purpose of this research is to study the relationship between the learning organization and organizational commitment among nursing managers. methods: this is a descriptive analytic survey. the population of study was 90 nursin...

This study examined the effects of rapid palatal expansion (RPE) and maxillary protraction headgear therapy in 18 patients with a skeletal Class III malocclusion (11 girls and seven boys; mean age 10.9 years) on upper airway dimensions compared with an untreated control group (nine girls and eight boys; mean age 10.9 years). Pre- and post-treatment cephalometric radiographs were traced and anal...

The energy bands of ordered CaCd and CaTl have been calculated by the nonrelativistic aug­ mented plane wave (APW) method. The electron structure in the system CaCdi_zTl.r is deduced from these calculations by using the rigid band model for the phases with O 'C z^l. The band structures of CaCd and CaTl are similar to the valence bands of other phases of the CsCl-type. From the energy eigenvalue...

Method A 12-year old boy (d-transposition of the great arteries and ASO (LeCompte maneuver) in the neonatal period) was referred for transcatheter pulmonary valve implantation due to pulmonary regurgitation. A 22-mm stentmounted valved bovine jugular vein graft (Melody valve, Medtronic, Minneapolis) was implanted, but the patient became hemodynamically unstable (pulmonary-tosystemic ratio 1.96)...

The aquatic ecosystem is the natural habitat of microorganisms including Vibrio and Aeromonas genus which are pathogenic to human and animals. In the present investigation the frequency of these bacteria and the enzymatic characteristics of 34 Vibrio alginolyticus strains isolated from bivalves harvested in Venice Lagoon (Italy) and Guanabara Bay (Brazil) were carried out from November 2003 to ...

The extremely high melting point and excellent resistance to oxidation and corrosion offered by iridium suggest numerous applications of this transition metal in static components at high temperatures and in aggressive environments. However, the mechanical and physical properties of f.c.c. Ir exhibit numerous anomalies when compared to other metals that crystallize in the f.c.c. structure. Nota...
