abstract solar radiation, nowadays has a lot of application in different fields of agriculture, irrigation, and hydrology engineering and due to these various applications, different models has been proposed for it’s estimation. angstrom-prescott equation is one of the most important well known models for solar radiation estimation. this equation has empirically coefficient that various for eac...

Behavior of relatively large size of diatoms which appear in the Ariake Sea areas, Japan in winter based on remote sensing satellite data is clarified. Through experiments with Terra and AQUA MODIS data derived chlorophyll-a concentration and truth data of chlorophyll-a concentration together with meteorological data and tidal data which are acquired for 5 years (winter 2011 to winter 2015), it...

The power supply methods for fixed-velocity-measuring system (FVMS) based on photovoltaic (PV) technology are proposed after analysis and comparison among the current methods for FVMS on freeway. According to the sunshine condition in typical low sunshine areas, all components consist of PV system are specially designed, including the related maximum power point track (MPPT) technology for sola...

The Sunshine Coast has long been a major producer of aggregate products that are readily consumed by the expanding markets of southwestern British Columbia and those south of the border. As part of an ongoing initiative of resource inventory, the Geological Survey Branch of the Ministry of Energy and Mines has undertaken an aggregate potential mapping project along the Sunshine Coast during the...

Further to Rose Mitchell's and Darren Savarimuthu's comments (letters June 20, July 4), I think they both need to look at why they wanted to be nurses in the first place.

Vitamin D is vital for human health, and its deficiency may result in hypocalcemic seizures and rickets in infants and children. The optimal cut-off of serum 25(OH)D levels to define vitamin D deficiency are yet to be established. While, the Endocrine Society of USA has suggested serum 25(OH)D < 20 ng/mL to define vitamin D deficiency [1], the Institute of Medicine (IOM), USA recommends a cut-o...

To coincide with the introduction in the United States of the Sunshine Act, Genevieve Pham-Kanter discusses what we need to look for to fight hidden bias and deliberate or unconscious corruption. Please see later in the article for the Editors' Summary.

In this issue of the British Journal of Nutrition, Islam et al. (1) and Woo et al. (2) present data from Bangladesh and China showing a high prevalence of poor vitamin D status in women of childbearing age combined with a concurrent elevation in plasma parathyroid hormone (PTH) concentration. These reports add to the growing evidence of a high prevalence of vitamin D insufficiency in countries ...

Published by Oxford University Press 2007. Although vitamin D is best known for its role in strengthening bone and preventing rickets, it is increasingly apparent that it may have beneficial health effects beyond the skeletal system, among them perhaps the prevention of a number of diseases, including cancer ( 1 ). These health effects have been the focus of two recent National Institutes of He...
