introduction the study of growth parameters such as net assimilation rate (nar), leaf area ratio (lar), relative growth rate (rgr) and leaf area duration (lad) are important for analyzing yield constraints. the growth parameters can be used to understand the crop response to environmental variables during the growing season. the aims of the present study were to 1) consider the growth indices u...

Epstein (1974a, 1986) and McCall (1988; McCall, Meyers, Hartman, & Roche, 1983) presented discrepant findings regarding the presence ofstages in brain arid.&ognitive maturation, as described in Piagetian theory. This article questions whether their variables (e.g., skull circumference and global mental test scores) are appropriate indices from which to make such conclusions. Evidence from direc...

A high prevalence of iron deficiency was found in apparently healthy Asian immigrant children in Harrow. After excluding children with overtly abnormal red cell indices, Asian and European children had identical haemoglobin values, but Asian children had much lower mean cell volume and mean corpuscular haemoglobin values and higher red blood cell values.

OBJECTIVE Many state trauma registries contain work-related information but are underutilized for occupational injury research/surveillance. We assessed three methods of identifying work-related injuries in the Washington State Trauma Registry (WTR). METHODS State-designated trauma facilities report traumatic injuries meeting specific inclusion criteria to the WTR. The WTR reports from 1998 t...

OBJECTIVES To explore injured patients' experiences of trauma care to identify areas for improvement in service delivery. DESIGN, SETTING AND PARTICIPANTS Qualitative study using in-depth, semi-structured interviews, conducted from 1 April 2011 to 31 January 2012, with 120 trauma patients registered by the Victorian State Trauma Registry and the Victorian Orthopaedic Trauma Outcomes Registry ...

Managers of the nearly 0.5 million ha of public lands in North and South Dakota, USA rely heavily on manual measurements of canopy height in autumn to ensure conservation of grassland structure for wildlife and forage for livestock. However, more comprehensive assessment of vegetation structure could be achieved for mixed-grass prairie by integrating field survey, topographic position (summit, ...

Highway work zones interrupt regular traffic flows and create safety problems. Improving safety without sacrificing the main function of highways is a challenging task that traffic engineers and researchers have to confront. In this study, the concept of using crash severity index (CSI) for work zone safety evaluation was proposed and a set of CSI models were developed through the modeling of w...

redbud (cercis griffithii) is an iranian native species that plays a crucial role in protecting soil and water in zagros forestsareas. although many reforestation projects of this species in this area were unsuccessful, the restoration of redbud must continue using new applied studies to help conserve this precious resource. this can be achieved through increasing the quality and quantity of se...
