In resource-limited populations, an increase in average body size can occur only with a decline in abundance. This is known as self-thinning, and the decline in abundance in food-limited populations is considered proportional to the scaling of metabolism with body mass. This popular hypothesis may be inaccurate, because self-thinning populations can also experience density-dependent competition...

Main Outcome Measures: Cortical thickness and change in cortical thickness on a vertex-by-vertex basis across the cortical mantle, measures of functional and symptomatic outcome, and cumulative intake of anti­ psychotiCS during the scan interval. Results: At baseline, the schizophrenic patients had thinner left orbitofrontal and right parahippocampal and superior temporal cortices and a thicker...

Dept.of Mechnical Design Eng., Chosun Univ., 375 Seosuk-dong, Dong-gu, Gwangju, Korea, [email protected] In this study, shearography and infrared thermography were used for measuring the wall thinning defects of the nuclear power plants pipes. It is very important to measure the wall thinning defects inside the pipes, because the wall thinning defects cause damage or destruction of the pipes. T...

This paper compares Hilditch, Rosenfeld, ZhangSuen, dan Nagendraprasad Wang Gupta (NWG) thinning algorithms for Javanese character image recognition. Thinning is an effective process when the focus in not on the size of the pattern, but rather on the relative position of the strokes in the pattern. The research analyzes the thinning of 60 Javanese characters. Time-wise, Zhang-Suen algorithm giv...

We investigated changes in the pattern of water use of an 8-year-old Eucalyptus nitens (Deane and Maiden) Maiden plantation soon after thinning. Sap flow sensors using heat pulse technology were deployed across three stands thinned to a final density of 100, 250 or 600 trees ha-1 plus an unthinned control (1250 trees ha-1). Changes in the relationship between tree size and daily water use were ...

equipment availability is necessary in the development of agriculture mechanization. crop thinning is one of the most important stages in row crop production which is laborious and costly. the objective of this project is design and construction of a row crop thinning machine. four main system units are plant sensors, ground sensors, control and thinning platforms. in this machine the unwanted ...

The effect of sensitivity of abscisic acid (ABA) on the power of self-thinning was studied with two Arabidopsis mutants (abi1-1, insensitive to ABA and era1-2 hypersensitive to ABA). The experimental results showed that the self-thinning power of abi1-1 (-1.49) was smaller than that of wild type (-1.35), and the self-thinning power of era1-2 (-1.21) was greater than that of wild type. Two param...
