The optimization of a pavement management system necessitates the knowledge on the actual values of pavement condition parameters, actual pavement condition improvement as related to the use of various rehabilitation strategies, and scope of pavement deterioration before and after rehabilitation. The data for six pavement condition parameters (bearing capacity, unevenness, rut depth, macro text...

This xction explains the harvesting system selected. based upon topography, soil condition. arid tree si~c. L /I is a highly mechmized, capital intensive s)*stern which includes tracked fellerbulltYlers to rut and bunch the trees. and trucked forwarders to transport the bunched trees to a H*/IO/CJ tree chipper. The chips will be loaded into vans md trunsported to a designated site. The total ca...

Two different optical configurations were developed and are described. The first is a laser profiling system that is used for transverse profile acquisition for rut detection purposes. The second uses an autosynchronized laser scanning sensor for crack detection Both these systems have been installed on inspection vehicles and have been tested. Tests have shown results that have a very good cor...

Introduction: Helicobacter pylori, as an etiologic cause of peptic ulcers and gastric cancer, should be tested and treated. The true state of infection can only be detected by isolation of gastric biopsies through the invasive method of gastroscopy. However, there are several non-invasive methods for detection of infection, the most common of which is serology. Methods: Here we have evaluated t...

During the rut, female ungulates move among harems or territories, either to sample mates or to avoid harassment. Females may be herded by a male, may stay with a preferred male, or aggregate near a dominant male to avoid harassment from other males. In fission-fusion group dynamics, female movement is best described by the group's fission probability, instead of inter-harem movement. In this s...

The addition of positively charged colloidal materials to the growth medium markedly increased the concentration of cellulase enzymes produced by Trichoderma reesei Rut-C30. Filter paper activities of up to 4 and 13 IU/ml have been achieved by the addition of colloidal materials, using 3% lactose and 3% cellulose, respectively, as a substrate. The particles exert their effect by binding soluble...

The water accumulated in the rutted road sections poses a threat to safety of vehicles. Water-filled ruts will cause partial or complete loss friction between tires and surface, leading driving hazards such as hydroplaning sliding. At present, maximum depth left right is mostly adopted analyze water-filled ruts, ignoring uneven change direction cross-section direction, which cannot fully reflec...

Soil surface is directly affected by heavy traffic of machinery during harvesting operations. Machine often causes damage to forest soil which visible on the (ruts) and invisible changes in, for example, bulk density, penetration resistance, etc. Close-range photogrammetry state-of-the-art method used recording evaluation changes. This study aims analyze caused three types wheeled skidders with...
