Tree diameter at breast height (dbh) and height are the most important variables used in forest inventory and management as well as forest carbon-stock estimation. In order to identify the key stand variables that influence the tree height-dbh relationship and to develop and validate a suit of models for predicting tree height, data from 5961 tree samples aged from 6 years to 53 years and colle...

Linear growth retardation during childhood is a determinant of short stature and impaired capacities in adults of developing countries. To study the effect of diarrhea on height during childhood, the authors followed a birth cohort of 224 Peruvian children for 35 months with records of daily diarrhea and monthly anthropometry. This study was conducted from April 1995 to December 1998. At 24 mon...

This study investigated the effects of ergonomic interventions involving a reduction of the mass (from 16 to 11 and 6 kg) and an increase in the initial lifting height (from pallet height to 90 cm above the ground) of building blocks in a mock-up of an industrial depalletizing task, investigating lifting behaviour as well as low back moments (calculated using a 3-D linked segment model). Nine e...

OBJECTIVE The efficacy and safety of height-limiting therapy with high-dose 17beta-oestradiol in girls with constitutionally tall stature (CTS) are controversial. We evaluated the effectiveness of high-dose 17beta-oestradiol in premenarchal girls with CTS treated until their bone age reached 14 years. DESIGN We retrospectively reviewed the medical records of the girls managed between 1989 and...

Methods Prospectively collected digital growth curves and menarche status of an inception cohort of 196 female patients with pSLE diagnosed <16 years and a minimal disease duration of 3 years were analysed. Abnormal growth was defined as i) one or more periods of growth arrest (<2 cm) lasting minimal 6 months, ii) more than one growth curve percentile difference between height at diagnosis and ...

The response of Carex lasiocarpa in riparian wetlands in Sanjiang Plain to the environmental gradient of water depth was analyzed by using the Gaussian Model based on the biomass and average height data, and the ecological water-depth amplitude of Carex lasiocarpa was derived. The results indicated that the optimum ecological water-depth amplitude of Carex lasiocarpa based on biomass was [13.45...
