Childhood sun exposure is a particularly important determinant of skin cancer, yet little data are available for children. This paper describes sun behaviour among Canadian children for the summer of 2006. As part of the Second National Sun Survey (NSS2), 1,437 parents reported on the time spent in the sun, and the frequency of sun protection behaviours and sunburning for one of their children ...

The aim of this study was to build on existing understanding of adolescent sun-related behavior by combining sun protecting and sun exposing behaviors and testing their relationship simultaneously with indicators of ultraviolet (UV) exposure. Data were collected for 692 adolescents aged between 12 and 18 years. General linear modeling was undertaken to test the relationship of sun-related behav...

Over the past few decades, several methods for designing shades to reduce energy loads of buildings have emerged. However, to date there are virtually no agreed upon methods available to assist in the design of outdoor shades to keep people comfortable. Here we present a novel method named ComfortCover to assist in the design of static shades in outdoor conditions using a 3-step methodology ada...

BACKGROUND In Denmark, the incidence of melanoma has been increasing since the 1960s. Intermittent exposure to ultraviolet radiation and a history of sunburn and sunbed use are known risk factors. We describe the association between use of protective measures, sun-related behaviour and experience of sunburn in the Danish population three months after the start of the campaign. METHOD A popula...

در این پایان نامه توزیع آماره های ترتیبی از توزیع نرمال دو متغیره و سه متغیره محاسبه می کنیم. همچنین به معرفی توزیع چوله نرمال یکریخت که با نماد sun نمایش می دهیم تابع مولد گشتاور این توزیع و برخی از خواص آن می پردازیم. نحوه ساختن توزیع sun را از توزیع نرمال سه متغیره ارائه می دهیم و نشان می دهیم که توزیع آماره های ترتیبی از توزیع نرمال سه متغیره به صورت مخلوطی از توزیع sun می شود.

During the development of woody twigs, the growth in leaf may or may not be proportional to the growth in stem. The presence or absence of a synchronicity between these two phenologies may reflect differences in life history adaptive strategies concerning carbon gain. We hypothesized that sun-adapted species are more likely to be less synchronous between growths in total leaf area (TLA) and ste...

<p>The green macroalgae <em>Ulva lactuca</em> (L.) is a potential alternative protein source. This study investigates the effect of soaking and different drying methods on color quality <em>U. lactuca</em>. Moisture ash content, color, i.e., crude protein, in vitro digestibility, solubility seaweed were determined. In its conduct, fresh was soaked water for various...

The personal radiant exposure distribution of solar erythemal UV in tree shade for an upright posture was measured, with measurements over the whole summer for a total of 17 trees. For each tree, the personal radiant exposure distribution was measured for both the morning and afternoon periods. The exposure ratios averaged over all the trees and over the morning and afternoon periods ranged fro...

So far, the main Arabica coffee breeding programmes in Latin America have focused on selection of varieties adapted to intensive full-sun farming systems. Meanwhile, little attention has been paid specifically shade, which is characteristic agroforestry systems (AFS). Yet specialty sector currently expanding and seeking specific sensory qualities related exotic no programme exists create new fo...
