Discussions on the controls initiating the onset of the phytoplankton spring bloom in particular in the North Atlantic have since Sverdrup been dominatedby the roleof physical andbiological drivers. Undoubtedly, these driversplayan important role inphytoplanktondynamics and thus the onset of the spring bloom. However, they neglect the cells ability to modify vital rates in response to changes i...

abstract: the new neonatal ventilation methods have been developed along with utilization of new technological tools.this device is synchronized with the patient’s respiratory efforts. the ideal synchronized breath needs to be synchronous with initiation, size, and termination of the breath without delay in detecting of initial resiratory effort by device .the synchrony of respiration contribut...

Anthropogenic disturbance has left the world's forests highly fragmented, with a significant proportion of edge-affected area. Abiotic changes at forest edges are likely to affect soil carbon cycling, as higher temperatures and lower moisture availability in edge environments have well-documented effects on respiration. The present study sought quantify persistent cycling fragmented broadleaf s...

UNLABELLED Subseafloor sediment hosts a large, taxonomically rich, and metabolically diverse microbial ecosystem. However, the factors that control microbial diversity in subseafloor sediment have rarely been explored. Here, we show that bacterial richness varies with organic degradation rate and sediment age. At three open-ocean sites (in the Bering Sea and equatorial Pacific) and one continen...

conclusions closed suction caused fewer disturbances in patients’ hemodynamic condition, took shorter time, and is more economical. therefore, this method can replace open suction method in caring of severely critically ill patients. results no significant differences were observed between the two suctioning methods in terms of mean systolic blood pressure (p = 0.075), diastolic blood pressure ...

Tillage and nitrogen (N) fertilization can influence soil organic matter (SOM) dynamics, but their interactive effects remain contradictory. A long-term (25 yr) corn (Zea mays L.)-soybean (Glycine max L. Merr.) rotation was used to investigate the effect of tillage [moldboard plow (MP) no-till (NT)] N rates (0, 80, 160 kg N·ha −1 ) on carbon (SOC), total (STN), respiration, SOM fractions [parti...

Microbial heterotrophic activity was investigated in oxic sub-seafloor sediments at North Pond, a sediment pond situated at 23°N on the western flank of the Mid-Atlantic Ridge. The North Pond sediments underlie the oligotrophic North Atlantic Gyre at 4580-m water depth and cover a 7-8 million-year-old basaltic crust aquifer through which seawater flows. Discrete samples for experimentation were...

background respiration management is an important and critical issue in prehospital transportation phase of multiple trauma patients. however, the quality of this important care has not been assessed in iran emergency medical services’ (ems). objectives this study was conducted to investigate the quality of prehospital respiration management in patients with multiple trauma, referred to the sha...

Contrasting effects of soil CO2 concentration on root respiration rates during short-term CO2 exposure, and on plant growth during long-term CO2 exposure, have been reported. Here we examine the effects of both shortand long-term exposure to soil CO2 on the root respiration of intact plants and on plant growth for bean (Phaseolus vulgaris L.) and citrus (Citrus volkainenana Tan. & Pasq.). For r...
