BACKGROUND The Functional Gait Assessment (FGA) is a reliable and valid measure of gait-related activities. OBJECTIVE The purpose of this study was to determine the concurrent, discriminative, and predictive validity of the FGA in community-dwelling older adults. DESIGN This was a prospective cohort study. METHODS Thirty-five older adults aged 60 to 90 years completed the Activities-speci...

This paper considers the application of 5GHz Wireless LAN technology to home networking applications. An assessment of physical layer petformarice is presented in the form of achievable data rate as a function of received signal to noise ratio. The transmit power Limitations imposed by the relevant regulatory bodies are also summarised. Based on this information, a state of the art propagation ...

BACKGROUND Activities-specific balance confidence (ABC) scale is a subjective measure of confidence in performing various ambulatory activities without falling or experiencing a sense of unsteadiness. OBJECTIVE This study aimed to examine the ability of the Hindi version of the ABC scale (ABC-H scale) to discriminate between fallers and non-fallers and to examine its predictive validity for p...

We sought to systematically evaluate the diagnostic and prognostic value miR106a in patients with colorectal cancer (CRC). An original study was conducted to explore correlations between tissue miR106a levels and outcomes for 138 patients diagnosed with CRC. To explore the diagnostic performance of miR106a, eligible studies were identified from medical databases from China and abroad. Based on ...

Objective. To examine whether anthropometric measures could predict diabetes incidence in a Chinese population during a 15-year follow-up. Design and Methods. The data were collected in 1992 and then again in 2007 from the same group of 687 individuals. Waist circumference, body mass index, waist to hip ratio, and waist to height ratio were collected based on a standard protocol. To assess the ...

BACKGROUND AND PURPOSE Falls are a significant public health concern for older adults; early identification of people at high risk for falling facilitates the provision of rehabilitation treatment to reduce future fall risk. The objective of this prospective cohort study was to examine the predictive validity of the Berg Balance Scale (BBS) for 3 types of outcomes-any fall (> or =1 fall), multi...

in order to evaluate physiological and morphological characteristics and yield of soybean (glycine max l.) cultivars under different planting ratios a field experiment was conducted based on randomized complete block design with four replications at the gaem shahr agricultural research centre of mazandran province, iran, during 2008. two soybean cultivars (032 and sari) were planted in row inte...

dry drainage could be considered as a natural system which evaporates water from fallow areas to control water table depth and soil salinity in neighboring cropped area. the technique requires the retirement of part of the irrigated land. one of the most notable design criteria for this system is to estimate the ratio of cropped to fallow strip width. a plexiglas physical model with the dimensi...

Estimates of distributions of natal dispersal distances and juvenile recruitment rates in open populations are strongly influenced by the extent and shape of the areas sampled. Techniques to improve biased dispersal and survival estimates include area-ratio methods based on weighting observations by sampling effort, the extent and shape of the area sampled, and the amount and distribution of pr...
