mowing. It is run along the ground on one large wheel which is f ree of the motor operat ing the cutter bar. I t can be tilted to cut up or down slopes and can be pivoted sharply in any direction. It has been found part icularly valuable for cutting around trees, boulders, t raps, creek-bottoms, and other golf course obstructions which formerly required hand cutt ing. The motor scythe, powered ...

Purpose: To investigate the current cutting down of trees as a human rights abuse in global world.
 Methodology: The study employed documentary review secondary data collection method. Documentary is technique which gathered from reports, journals, Magazines, Newspapers, and articles that have linked to research being undertaken (Creswell, 2014). A was world by examining causes, impacts, h...

Trees alter microclimate and radiation budget in alley cropping systems, which turn change physiological processes of the grassland component. The influence trees on growth depends climate zone as well possibly weather conditions during respective interval. proportion shade-tolerant species further modifies tree effect growth, number annual harvests. We studied distance orientation relative to ...

Abstract The native stands of ‘candeia’ (Eremanthus erythropappus) have been explored through management plans due to the economic potential essential oil. rescue adult trees, as well application silvicultural techniques that favor restoration stand, can contribute genetic conservation this species. This study’s objective was assess efficiency propagation for 26 matrices in a natural managed st...

in order to help in the engineering design of rice harvesting machines, there is a need to have exact information concerning the physical and mechanical properties of rice stems. the cutting force for rice stems, therefore, was measured by designing and fabricating a static and dynamic shear test apparatus. the effects of moisture levels and the cross-sectional area of stem as well as the varie...

--Girdling roots are examined and described on streetside Norway maple trees (Acer platanoides L.) in Ann Arbor, Michigan. Treatments consisting of cutting girdling roots, fertilizing and pruning foliage were evaluated after two years and found to be of no benefit to girdled trees. From August 1977 to August 1979 this study was made on 410 Norway maple trees (Acer platanoides L.) planted betwee...

The conversion of coniferous tree plantations towards natural self-regenerating forests is one the targets forestry in Europe and particularly desirable national parks. aim this study was to evaluate effectiveness different approaches (conducted once) on forest development man-made spruce plantations. We studied effects three distinct management options (partial-cutting [PC], clear-cutting with...

Experience the precision of time: radiocarbon 3.0 RESOLUTION aims to achieve an accurate and highly resolved chronology back 55 000 years BP (Before Present), using some new floating sections fossil trees. In fact, with tree rings, resolution will be order magnitude higher, most recent advances in AMS technique, we obtain confidence intervals only a few centuries glacial times. this way, can es...

In the laser cutting process some well-known parameters, e.g. laser power and cutting speed, play major roles in the performance of the process. Each parameter or a combination of parameters can affect the material removal volume and cutting volume efficiency. The purpose of this research is to study the effect of power and maximum cutting speed on the material removal rate (MRR) and cutting vo...
