UNLABELLED BACKGROUND Growth rate In children is reported to have seasonal variability. There are fewer published data regarding seasonal variability while on growth hormone (GH) therapy, and none analyzing growth rate with respect to number of daylight hours. METHODS We analyzed 11,587 3-month intervals in 2277 prepubertal children (boys ages 3-14 years, girls ages 3-12 years) with idiopa...

1. While several reports of photosensitive pigments from the retinas of animals possessing large numbers of cone cells have been published, the only study which could be confirmed was Wald's discovery of iodopsin, a red-sensitive pigment from chicken eyes. 2. In its chemical properties, such as the range of pH stability and the effect of polar organic solvents, iodopsin resembles rhodopsin but ...

External shading devices are an important design feature in tropical buildings, particularly for climate mitigation. However, the interaction between depth and elevation of their impact on indoor daylight performance is not fully understood, especially case buildings with bilateral openings. This study therefore aims to evaluate possibilities external various terms school classrooms openings In...

Using natural light in architectural spaces has been very beneficial several ways including energy efficiency, cost control, health and wellbeing of users, prevention electricity dissipation other negative effects artificial lighting. Daylight architecture satisfies both mental physical human needs reduces fossil consumption. This paper appraised the use daylighting sustainable housing developm...

landscape metrics quantifies structural features of the landscape. one of the advantages of these metrics is a possibility to use them in fast cumulative assessment of the development activities in the environment. in this paper, the cumulative effects of road network expansion on the tree cover of gorgan, kordkuy, aliabad townships in golestan province were investigated. to prepare the require...

Reuse economics has been the subject of vigorous study over the past several years. Although significant progress has been made in the areas of reuse metrics and cost estimation, much work to date in reuse investment analysis has not always reflected accepted mainstream financial analysis practices. This paper compares several approaches that have been described in the reuse literature, points ...

using the electrostatic capacity of a condenser, the existence of a distance function on a finsler space is discussed. this distance function divides finsler spaces into the two classes, denoted here by i and ii. the topology generated by this distance on the finsler spaces of class ii coincides with its intrinsic topology. this work provides a natural extension of mathematical analysis tools n...

A new daylight simulation method for radiosity environments is presented. Daylight illumination is transported in a first step where sun and sky are represented as a set of directional sources. Light is transported using parallel projections of these sources. The scene mesh is adaptively subdivided using energy and visibility criteria obtained from a extended scan-line algorithm that computes a...
