Under the direction of Professor Agnès Noël, a team of scientists at the GIGA-Cancer research center of the University of Liège has developed, in collaboration with other European laboratories, a new lymphoangiogenesis model which could lead, among other things, to a better understanding of cancer cell dissemination (metastases). This finding is the subject of an article published in the renown...

Stick insects (Carausius morosus) have two distinct types of attachment pad per leg, tarsal "heel" pads (euplantulae) and a pre-tarsal "toe" pad (arolium). Here we show that these two pad types are specialised for fundamentally different functions. When standing upright, stick insects rested on their proximal euplantulae, while arolia were the only pads in surface contact when hanging upside do...

Stand development involves changes in stand structure over time. Knowledge of stand development patterns is crucial for effective forest management, especially of southern bottomland hardwood forests. These forests contain more than 70 tree species, many of which have commercial timber and wildlife habitat value. I n this paper, current techniques i n stand development research are reviewed. Em...

The present study examined whether a sit-to-stand score can be related to the force-generating capacity of knee extensor muscles. Fifty-seven subjects (28 men, 63.0+/-7.8 yrs, and 29 women, 64.2+/-7.5 yrs, means+/-SDs) performed a 10-repeated sit-to-stand test as fast as possible, on a steel molded chair. The time taken (T(sit-stand)) was measured with a manual stopwatch. The leg length (L), de...

This study was performed to estimate stand-level volume using the characteristics of vertical and horizontal distribution of airborne Light Detection And Ranging (LiDAR) data. It is found that the height distributional parameters, such as percentile, of LiDAR data reflected onand in-canopy in a stand have the relationship with stand volume in previous research. However, we assumed that the nonp...

ABSTP, ACT. Growth data from the most recent 5 years of a 40-year thinning study in an even-aged red pine (Pinus resinosa) forest in Cutfoot Sioux Experimental Forest, Minnesota, were used with intercepted photosynthetically active radiation (IPAR) data to determine the relationship between light interception and growth for a range of stand densities. Stand basal area (BA) growth was proportion...

the forging model for cold rolling is one of rolling models that is used in rolling calculations. in this model,the final rolling pressure is an average value and it is not an accurate model.also by using this model,the firction hill curves are plotted due to the central point of the rolling bite length while frictional stresses intersect at the neutral point.in this study, a new model based on...

We analyzed the relationship between Landsat ETM+ reflectance values and commercially managed loblolly pine (Pinus taeda L.) stand characteristics in east Texas. Multivariate regression techniques were used to predict age and tree density for all stands. A linear combination of NDVI, ETM4/ETM3 and the tasseled cap wetness index was a better predictor of stand age (R = 78%) than other combinatio...

Remote sensing has been considered a low-cost, large-area coverage forest information resource ideally suited to broad-scale forest inventory objectives. The objective of this study is to determine stand type parameters such as crown closure, development stage and stand types, and land cover obtained from Landsat 7 ETM image and forest cover type map (stand type map). The research also focuses ...
