• Background and Aims Despite differences in physiology between dry and relative moist seeds, seed ageing tests most often use a temperature and seed moisture level that are higher than during dry ...

Hypoxemia is defined as a condition where arterial oxygen tension or partial pressure of oxygen (PaO2) is below the normal value, which is typically between 80 and 100 mmHg. Alveolar ventilation is ...

The effect of O2 partial pressure on the germination and the respiration of 12 cultivated species was studied. The reciprocal of the time necessary to observe rootlet emergence in 50% of the seeds was ...

OXYGEN deficiency is one of the most common of all categories of atmospheric hazards. It stands to reason that the sensors used to measure oxygen concentration are one of the most widely used types of ...

ARTERIAL oxygenation during apnea may now be studied with greater accuracy. The recent development of the polarograph 1–3 has made it possible to obtain direct arterial-oxygen-tension determinations ...

Injuries suffered at high elevations are associated with a significantly higher odds of developing deep vein thrombosis (DVT) ...

A baby girl presented with symptomatic sickle cell disease exacerbated by mild hypoxemia, despite a newborn-screening diagnosis of sickle cell trait. DNA sequencing of the β globin gene revealed that ...
