Background & Objective: Cardiovascular disease (CVD) is the main cause of morbidity and mortality in most countries. By identifying the population attributable risk (PAR) of the main risk factors of CVDs, the overall effect of various exposures on a population can be determined; the findings could be used in CVD prevention. The present study aimed to explore the PAR of some factors, includin...

Method for tealeaves quality estimation through measurements of Degree of Polarization: DP, Leaf Area Index: LAI, Photosynthesis Available Radiance: PAR and Normalized Difference Vegetation Index: NDVI for characterization of tealeaves is proposed. The method allows estimations of PAR, NDVI, Grow Index: GI by using measured Degree of Polarization: DP of tealeaves. Through experiments at the tea...

Interception of photosynthetically active radiation (PAR) was evaluated relative to greenness and normalized difference [MSS (7 5)/(7 + 5)] for five planting dates of wheat for 1978-79 and 1979-80 at Phoenix, Arizona. Intercepted PAR was calculated from leaf area index and stage of growth. Linear relationships were found with greenness and normalized difference with separate relationships descr...

Résumé. L’indexation est l’une des techniques d'optimisation redondantes qui accélère les requêtes OLAP. Deux types d’index sont disponibles : les mono-index (B-tree, index binaire, projection, etc.) et les multi-index (index de jointure). Pour un entrepôt représenté par un schéma en étoile, les index de jointure binaires sont souvent utilisés pour accélérer les requêtes de jointure en étoile c...

BACKGROUND The aim of this retrospective study was to analyse the treatment time and differences between the pre- and post-treatment peer assessment rating (PAR) index and aesthetic component (AC) of the index of orthodontic treatment need (IOTN) scores in children/adolescents with special health care needs (SHCNs), compared to non-special health care needs (NSHCNs) controls. METHODS Based on...

Cardiac autonomic dysfunction is a serious condition in elderly and diabetic subjects. Baroreflex sensitivity (BRS), measured from pulse intervals and blood pressure, has been proven as an effective indicator. This paper proposes an index that replaces blood pressure with amplitudes of the pressure pulse. 89 subjects were recruited and divided into three groups: healthy young subjects (Group 1,...

The amount of photosynthetically active radiation (PAR) absorbed by a canopy (APAR) is an important driving variable for vegetation processes such as photosynthesis. PAR extinction in clumped canopies of shortgrass ecosystems is the focus of this paper. Directional gap fractions estimated at peak biomass on several Mexican shortgrass ecosystems with a hemispherical radiation sensor (Li-Cor, LAI...

in order to investigate the effect of urea and azocompost on economic yield, nitrogen use efficiency (nue) and radiation use efficiency (rue) of wild majoram, a factorial experiment was conducted based on randomized complete block design with three replications at yazd and mashhad, iran, during 2012-2013 growing season. four urea levels and four azocompost levels (to provide 0, 40, 80 and 120 k...

Landsat imagery was used to study the relationship between a remotely sensed burn severity index and prefire vegetation and the postfire vegetation response related to burn severity within a 1986 burn in interior Alaska. Vegetation was classified prior to the fire and 16 years after the fire, and a chronosequence of remotely sensed vegetation index values was analyzed as a surrogate of vegetati...
