The dynamics and microdistribution of faunal assemblages at hydrothermal vents often reflect the fine-scale spatial and temporal heterogeneity of the vent environment. This study examined the reproductive development and population structure of the caridean shrimp Rimicaris hybisae at the Beebe and Von Damm Vent Fields (Mid-Cayman Spreading Centre, Caribbean) using spatially discrete samples co...

The complete seating of full coronal restorations during cementation is hindered by the inability of cement to flow from the internal surface of the crown, and possible binding of the crown on the tooth. Perforation venting is an effective technique to allow full seating but requires repair of the perforation. Provision of space between the crown and the tooth for cement flow is also an effecti...

Using the Illumina sequencing technology, we investigated the vertical distribution of archaeal community in the sediment of Zhushan Bay of Lake Taihu, where the black bloom frequently occurred in summer. Overall, the Miscellaneous Crenarchaeotal Group (MCG), Deep Sea Hydrothermal Vent Group 6 (DHVEG-6), and Methanobacterium dominated the archaeal community. However, we observed significant dif...

Population densities of the root-knot nematode, Meloidogyne incognita, were lower after 90 days in soil planted to digitgrass (Digitaria decumbens cv. Pangola) than in soil left fallow or planted to tomato. Roots of tomato seedlings interplanted with Pangola digitgrass were less galled than were roots of tomato seedlings planted alone. Fewer second stage larvae invaded roots of Pangola digitgra...

Bacterial communities at a CO2 vent (pH 6.7) were compared with those at control (pH 8.0) and transition sites (pH 7.6) using 16S rRNA metagenomics. Firmicutes and unclassified bacteria dominated across all sites, Proteobacteria, especially Gammaproteobacteria, declined, and Epsilonproteobacteria increased in the vent with an increase in Bacteroidetes at both the vent and transition sites.

influence of a vent hood at the exit of exhaust flue gas and flue baffles in the firetube on the temperature and flow fields of a gas tank water heater, as well as thestructure and amount of heat transferred to the water tank has been studiednumerically using two-dimensional steady state finite element simulation.observations show that without a vent hood, there is a downward gas flow in theflu...

Chemosynthetic primary production by microbes supports abundant faunal assemblages at deep-sea hydrothermal vents, with zonation of invertebrate species typically occurring along physico-chemical gradients. Recently discovered vent fields on the East Scotia Ridge (ESR) in the Southern Ocean represent a new province of vent biogeography, but the spatial dynamics of their distinct fauna have yet ...

BACKGROUND Since rising medical costs currently represent a growing problem worldwide, finding cost-effective treatment options is important. In our hospital, outpatient treatment of pneumothorax using a thoracic vent began in December 2012. OBJECTIVES We aimed to test our hypothesis that outpatient treatment of pneumothorax with a thoracic vent can reduce medical expenses. METHODS Patients...

pposites really do attract. Results on page 101 by Oliveria et al. show that, although they perform opposing functions, a kinase and a phosphatase linked to synaptic plasticity are close neighbors at the plasma membrane. The two are brought together by the scaffolding protein AKAP79 into a complex that may be important for efficient learning. The close proximity of the three proteins is uncover...
