This paper summarizes research conducted to investigate the problem of forward visibility while driving during inclement weather. A review of the literature indicates that using narrow-distribution lamps, mounted away from the driver's line of sight, would result in the lowest amount of back-scattered light. The literature also indicates that the spectral content of light can influence glare an...

Prof. Sang-In Kim would have been greatly proud and happy to see us advancing the Laboratory Medicine if he could have stayed with us longer. We feel the deepest sorrow after he had left us so soon. Having strongly endured the long fight against the disease, he even attended the transfusion conference several months ago, there he smiled and grabbed our hands with his warm heart. On the day he w...

Driving through rain results in reduced visual performance, and car designers have proposed countermeasures in order to reduce the impact of rain on driving performance. In this paper, we propose a methodology dedicated to the quantitative estimation of the loss of visual performance due to the falling rain. We have considered the rain falling on the windshield as the main factor which reduces ...

Thirty-two groups of six sheep, classified into three breed categories according to their weight class (L: light, one breed (n=7); M: medium light, two breeds (n=10); H: heavy, three breeds (n=15)) were tested for antipredatory behaviour towards seven stimulus regimes. Tests were performed on 2-5-years-old ewes with lambs inside standardised and fenced home pastures. Stimulus regimes were: man ...

This study makes use of operational global ensemble forecasts from the European Centre for MediumRange Weather Forecasts (ECMWF) to examine the factors contributing to, or inhibiting, the development of a long-lived continental vortex and its associated rainfall. From 25 to 30 June 2007, a vortex developed and grew upscale over the southern plains of the United States. It was associated with pe...

Strong phytoplankton blooming in tropical-cyclone (TC) wakes over the oligotrophic oceans potentially contributes to long-term changes in global biogeochemical cycles. Yet blooming has traditionally been discussed using anecdotal events and its biophysical mechanics remain poorly understood. Here we identify dominant blooming patterns using 16 years of ocean-color data in the wakes of 141 typho...

Climate change is already affecting high mountain regions, such as the European Alps. Those regions will be confronted with a significant rise of temperatures above global average, and more heavier rain events, also during wintertime. The system response to coincidence rain, snow, possibly frozen soil depends on almost infinite number possible combinations thermo-hydraulic states involved phase...

background: there is increasing evidence that visual impairment contribute to falling. the aim of this study was to determine the influence of vision impairment of old adult patients with cataract on the occurrence of falls and postural control. methods:according to the results of screening ophthalmic examination, 48 cataract patients (mean±sd aged 68.5 ± 6.08 yrs.) and 50 individuals without a...
