In autumn 2002, an outbreak of probable psittacosis occurred among residents of the Blue Mountains district, Australia. We conducted a case-control study to determine independent risk factors for psittacosis by comparing exposures between hospitalized patients and other residents selected randomly from the telephone directory. Of the 59 case-patients with laboratory results supportive of psitta...

Deforestation in the tropics often leads to unproductive agriculture, and results in 1 abandoned, degraded grasslands that tree species re-colonize poorly. To evaluate why forests do 2 not regenerate naturally, and to identify potential species for use in reforestation of degraded 3 areas, we planted 15,000 seeds of twenty native tree species varying in seed size and shade4 tolerance, in abando...

PURPOSE The purpose of the study was to investigate changes in lower extremity joint energy absorption for different landing heights and landing techniques. METHODS Nine healthy, active male subjects volunteered to perform step-off landings from three different heights (0.32 m, 2.5 m(-s); 0.62 m, 3.5 m(-s); and 1.03 m, 4.5 m(-s)) using three different landing techniques (soft, SFL; normal, NM...

T he heart, lungs, blood, vasculature, and skeletal muscle integrate in a complex way to allow humans to interact with their environment, through locomotion and other forms of physical exercise (1). This interaction becomes challenged in people with the clinical syndrome of heart failure (HF) (2). In addition to the very reasonable desire to live longer, people with HF also want to be able to d...

Heterostyly (i.e., reciprocal placement of anthers and stigmas between two or three floral morphs) is hypothesized to enhance outcrossing and reduce selfing. However, few studies have documented reciprocity among individual plants; instead, mean anther and stigma heights for floral morphs are usually reported, masking interindividual variation. We measured eight floral dimensions for individual...

For the first time, global ocean usable wind power is evaluated for modern offshore turbine characteristics including hub height, usable portion of the wind speed distribution and siting depth. Mean wind power increases by 30%, 69% and 73% within the tropics and northern and southern hemisphere extratropics, respectively, between hub heights of 10 m and 100 m. A turbine with a cut-out speed of ...

this research was conducted to investigate the effect of planting space on fiber morphology of acer velutinum. in this work, from each treatment including planting space of 1×1, 1.5×1.5 and 2×2 meters, four trees were cut from shastkalateh plantation of gorgon university and factors such as length and annual diametrical growth of trees as well as length, diameter and wall thickness of fibers we...

In this paper, we present a video-based method of detecting fall incidents of the elderly living alone. We propose using the measures of humans’ heights and occupied areas to distinguish three typical states of humans: standing, sitting, and lying. Two relatively orthogonal views are utilized, in turn, simplifying the estimation of occupied areas as the product of widths of the same person, obs...
