Population densities of Belonolaimus longicaudatus, Pratylenchus brachyurus, and Trichodorus christiei were determined from soil samples taken weekly in Tifton, Georgia during a 14-month period (except for April and May) at 15-cm increments to a depth of 105 cm. Belonolaimus longicaudatus predominately inhabited the top 30 cm of soil that was 87-88% sand, 6-7% silt, and 5-7% clay. No specimens ...

The present study evaluated the effects of different cutting height on nutritive value, fermentation quality, in vitro and in vivo digestibility of whole crop barley silage. Whole crop barley forage (Yuyeon hybrid) was harvested at height of 5, 10, and 15 cm from the ground level. Each cutting height was rolled to make round bale and ensiled for 100 days. After 100 days of ensiling, pH of silag...

BACKGROUND Vascular leakage has been proven to play a critical role in the incidence and development of explosive pulmonary barotrauma. Quantitatively investigated in the present study was the severity of vascular leakage in a gradient blast injury series, as well as ultrastructural evidence relating to pulmonary vascular leakage. METHODS One hundred adult male New Zealand white rabbits were ...

Standards of low electrolytic conductivity were developed to satisfy the demands of the U.S. Navy and American industry for the measurement of high quality water. The criteria for the selection of appropriate solvent and solutes, based on the principles of equivalent conductivity and Onsager's limiting law, are described. Dilute solutions of potassium chloride and benzoic acid in 30 % n-propano...

BACKGROUND The literature generally describes the trachea as oriented toward the right and back, but there is very little detailed characterization. Therefore, the aim of this study was to precisely determine the spatial orientation and to better characterize the physical properties of the human trachea. METHODS We analyzed lung computed tomography scans of 68 intubated and mechanically venti...

The vascular pressure-flow (P-Q) relationships in zone II (West et al.) were studied in isolated canine left lower lobes, in order to characterize the total resistance in the pulmonary vascular bed with respect to incremental or flow resistance and critical closure. At each of five levels of static lung inflation, the P-Q relationship was curvilinear at low flow and rectilinear at higher flows....

Circulating lipoproteins may offer interesting properties as therapeutic carriers for cytokines and hormones, in terms of both stability and bio-distribution. The fusion of apolipoprotein A-I with interleukin-15 (IL-15) targets the latter to high-density lipoproteins (HDLs). The bioactivity of this chimera can be further enhanced by creating triple fusions with IL-15 receptor α domain involved ...

For isolated objects in complete darkness, retinal image size contributes to distance judgments even if the true object size is unknown. Here we show that the same is true under more natural conditions. On a wide beach we positioned a red cube at 10-20 m distance and then asked subjects to walk to it while blindfolded. Subjects never had a close view of the cube and were unaware that on separat...

The use of grazing management strategies can influence canopy structure and the permanence legumes. objective this work was to evaluate determination forage heights as a strategy regarding herbage mass composition tiller population dynamics in multispecies pastures comprising Megathyrsus maximus cv. Aruana legumes Macrotyloma axillare, Calopogonium mucunoides Stylosanthes spp. Four treatments, ...
