We identify global observed changes in dry-spell characteristics that are consistent with future projections and involve common physical drivers. Future of longer dry spells the season increase vegetation water stress can negatively impact perennial vegetation. Lengthening up to ?2 days per decade over South America southern Africa shortening similar magnitude West display a qualitatively patte...

atmospheric circulation patterns are responsible for drought and flood occurrences around the globe specifically in moderate mid latitude climates. while some circulation patterns are responsible for wet spells and floods as well, the drought events can be attributed to some other circulation patterns. therefore, identification and distinction of dry/wet producing patterns and the geographical ...

Tissue or nerve injury can dramatically alter the transmission of sensory stimuli by spinal cord neurons, so that a light touch produces pain. The discovery that peptide products of prepronociceptin processing either facilitate or inhibit these mechanisms suggests novel approaches to treating these conditions.

BACKGROUND There is substantial evidence that mortality increases in low temperatures. Less is known about the role of prolonged cold periods denoted as cold spells. OBJECTIVE We conducted the first systematic review and meta-analysis to summarize the evidence on the adverse health effects of cold spells in varying climates. DATA SOURCES AND EXTRACTION Four databases (Ovid Medline, PubMed, ...

In tropical no-till systems, applying lime (L) and phosphogypsum (PG) on the soil surface may be a potential strategy for reducing acidification improving soybean root growth, thereby enhancing plant nutrition physiological responses and, in turn, crop resistance to dry spells. This study evaluated impact of long-term (17 years) amendment fertility development, nutrition, gas exchange, carbon a...

CONTEXT Sick leave is a major problem in public health. The Karasek demands/control/social support/strain (JDCS) model has been largely used to predict a wide range of health outcomes and to a lesser extent sickness absence. STUDY OBJECTIVE The aim of the study was to test the predictive power of the JDCS model in relation with one year incidence of sick leave in a large cohort of workers. ...
