Ribonucleases protect RNA from acid precipitation
Four, widely used, ribonucleases were found to protect their substrates from acid precipitation by causing, evidently, a modification of their physicochemical properties. The protection was dependent on the kind of substrate ...
The accumulation of pleural fluid during labour
Objectives: Labour appears to promote the development of pleural effusion. The presence of pleural fluid at the end of normal pregnancy and after an uncomplicated labour was investigated using thoracic ultrasonography. ...
Greenhouse ventilation rates through combined roof and side openings: An experimental study
A simple statistical relation between the ventilation rate of a greenhouse and its roof and side openings was proposed and tested on experimental data. This relation combines thermal buoyancy and wind effects as driving ...
Motor fibers in the sural nerve of humans
Although motor fibers in the sural nerve were already described in three individuals, this nerve is considered purely sensory. We investigated the occurrence of motor fibers in 331 sural nerves of 207 individuals. We found ...
Effects of soil compaction, water and organic matter contents on emergence and initial plant growth of cotton and sugar beet
The effects of compaction on the emergence and initial growth of cotton and sugar beet plants were studied in pots in a glasshouse experiment. Apart from compaction, the factors studied were two soil types, two initial ...
Natural ventilation performance of six greenhouse and tunnel types
The physical basis of natural ventilation is reviewed and the ventilation performance examined of six different greenhouse and tunnel types equipped with either roof or side, or both roof and side vents. Altogether, sixteen ...
Neutron diffraction on purple membranes - Essential water molecules in the light-driven proton pump bacteriorhodopsin
Neutron diffraction and time-resolved laser-spectroscopic experiments on the light-driven proton-pump bacterio-rhodopsin revealed the location of water molecules and their functional importance. About seven water molecules ...
Pulmonary function abnormalities in young adults with thalassemia major
Thalassemia seems to be the most common genetic disorder. The pathophysiologic mechanisms for lung impairment is not clear. Lung function tests in children showed small airway obstruction and restrictive lung changes. ...
Peripartum pleural effusion
