The Epidemiology of Sickle Cell Disease in Sub-Saharan Africa: Current Knowledge and Gaps to be Filled. [PDF]

Am J Hematol
What are the available data on incidence & prevalence prognosis risk factors of severity of sickle cell disease in sub‐Saharan Africa? ABSTRACT Sickle Cell Disease (SCD) is highly prevalent in sub‐Saharan Africa. Epidemiological data remain sparse, but regional screening and research initiatives are expanding.

Reduction of optical noise in near-infrared range laser hygrometry [PDF]

Metrology and Measurement Systems, 2023
A contactless laser hygrometer based on light absorption by H2O molecules at 1392.5 nm is described. However, measurement results can be affected by optical noise when applied to an atmospheric tunnel or glass cuvette.

The Late- Cretaceous volcanic rocks from Talesh area (western Alborz): chemical variation, crystallization condition, hygrometry and tectonic setting [PDF]

پترولوژی, 2020
In the Talesh area (western Alborz), a thick sedimentary- volcanic association formed in a littoral- deltaic environment during the Late Cretaceous. The extrusives comprise volcanoclastics (tuffs), lava flows (pillow and massive) and basic dykes.

Large Variations in the Transpiration of Sorghum Canopies Under High Evaporative Demand Are Positively Related to Water Use Efficiency. [PDF]

Plant Cell Environ
ABSTRACT Transpiration restriction under high vapour pressure deficit (VPD), measured indoors with individual plants, increases water use efficiency (WUE). However, VPD is not the only factor driving transpiration, individual plants in a field rapidly become a canopy, and reports on the transpiration restriction versus WUE are scant.

Experimental study of the influence of the relative humidity of leaves and their link to adhesion losses in the wheel-rail contact

Mechanics & Industry, 2022
Every autumn, low levels of wheel–rail contact adhesion caused by leaves on the railhead surface are reported by train drivers. These incidents cause problems for the safety and regularity of rail traffic and occur predominantly at the beginning and end ...

Variation of Seasonal Temperature and Water Stress Modify the Composition of Leaf Essential Oils in Grapefruit (Citrus x aurantium var. paradisi), Sweet Orange (Citrus x aurantium var. sinensis) and Clementine (Citrus x aurantium var. clementina) Trees. [PDF]

Chem Biodivers
ABSTRACT Mainly grown for food, citrus trees are also highly used as sources of aromatic essential oils (EOs) by the cosmetics and perfume industries. The EOs composition is highly complex with more than hundred compounds. It varies according to cultivation techniques, climatic conditions, and environmental stresses, whether of biotic or abiotic origin.

Technologies for equine welfare and performance monitoring under field conditions - Where do we stand? [PDF]

Equine Vet J
Abstract The need for comprehensive equine welfare assessments has become particularly evident amid ongoing debates about the social licence to operate in equestrian sports. During exercise, multiple physiological systems, principally the cardiovascular, respiratory, muscular, thermoregulatory, endocrine, and locomotory systems, undergo complex ...

Atmospheric moisture supersaturation in the near-surface atmosphere at Dome C, Antarctic Plateau [PDF]

Atmospheric Chemistry and Physics, 2017
Supersaturation often occurs at the top of the troposphere where cirrus clouds form, but is comparatively unusual near the surface where the air is generally warmer and laden with liquid and/or ice condensation nuclei. One exception is the surface of the
