Drained thermokarst lake basins accumulate significant amounts of soil organic carbon in the form of peat, which is of interest to understanding carbon cycling and climate change feedbacks associated with thermokarst in the Arctic. Remote sensing is a tool useful for understanding temporal and spatial dynamics of drained basins. In this study, we tested the application of high-resolution X-band...

STUDY OBJECTIVE To assess the accuracy of chest ultrasonography in predicting pleural effusions > 500 mL in patients receiving mechanical ventilation. DESIGN Prospective study. SETTING Surgical and medical ICU in a teaching hospital. PATIENTS Forty-four patients receiving mechanical ventilation with indications of chest drainage of a nonloculated pleural effusion. INTERVENTIONS Diagnosi...

One of the biggest challenges in predicting ecohydrologic fluxes is scaling from easily measured variables to more difficult, often emergent patterns and processes. This is especially true in spatially heterogeneous systems such as black spruce (Picea mariana)dominated boreal forests containing excessive and low soil moisture conditions. Traditional hypotheses suggest that transpiration is cont...

NT will reduce soybean grain yields and economic returns, particularly during the first few years of adoption. Farmers have been encouraged to adopt no-tillage (NT) because Soybean grain yield response to NT systems depends of its positive environmental effects compared with other conservation tillage systems. Nevertheless, poor crop performance under NT manmainly upon soil drainage and previou...

A 3-week-old female underwent transthoracic echocardiography (iE33, Philips medical system, Andover, MA, USA) to evaluate a grade 1 systolic murmur. In the subcostal view, blood flow in the inferior vena cava drained to the right atrium, while no blood flow from the superior vena cava to the right atrium was noted (Figure 1A). In the four-chamber view, no superior vena caval blood flow was seen...

BACKGROUND A study was undertaken to compare the efficacy of short term tube thoracostomy drainage with standard tube thoracostomy drainage before instillation of tetracycline for sclerotherapy of malignant pleural effusions. METHODS The study consisted of a randomised clinical trial in a sequential sample of 25 patients with malignant pleural effusions documented cytopathologically. Fifteen ...

BACKGROUND Prolonged and excessive drainage of serous fluid and seroma formation constitute the most common complications after mastectomy for breast carcinoma. Seroma formation delays wound healing, increases susceptibility to infection, skin flap necrosis, persistent pain and prolongs convalescence. For this, several techniques have been investigated to improve primary healing and minimize se...

The Water-Fluctuation-Zone (WFZ) of the Three Gorges Reservoir (TGR) has a special combination of aquatic and terrestrial ecological systems that are exposed to human activity. In this work, three kinds of soil were sampled along the Yangzi River in the TGR-WFZ. Our study focused on phosphorus (P) sorption characteristics and the change in inorganic P fractions for soils in alternately waterlog...

Rewetted, previously drained fens often remain sources rather than sinks for carbon and nutrients. To date, it is poorly understood which soil characteristics stimulate carbon and nutrient mobilization upon rewetting. Here, we assess the hypothesis that a large pool of iron in the soil negatively affects fen restoration success, as flooding-induced iron reduction (Fe3+ to Fe2+) causes a disprop...

Boundaries on the new map of the Natural Vegetation of Ohio by Gordon (1966) neatly follow, in most places, geologic boundaries. Where this is not true, conditions controlling this distribution are either aspect, microclimate, or the result of some as-yet unrecognized variation in the geology. Vegetation-geology correlations may be generalized as follows. Beech (-maple) forests occur on better ...
