the goals of The World Endoscopy Organisation (WEO) Colorectal Cancer Screening Committee (CRCSC) are: • To provide a forum for international professional interaction in the area of screening for colorectal cancer (CRC). • To promote innovation (developing, testing and promoting advances) and effective practice in the screening and surveillance for CRC. • To collaborate with fellow professional...

Variable-order fractional diffusion equation model is a recently developed and promising approach to characterize time-dependent or concentration-dependent anomalous diffusion, or diffusion process in inhomogeneous porous media. To further study the properties of variableorder time fractional subdiffusion equation models, the efficient numerical schemes are urgently needed. This paper investiga...

The paper is concerned with nonautonomous generalised Nicholson systems under conditions which imply their permanence: by refining the assumptions for permanence, explicit lower and upper uniform bounds all positive solutions are provided, as well criteria global exponential stability of these systems. In particular, periodic systems, existence a globally exponentially attractive solution deriv...

A prototype mobile chip harvester has been designed to harvest forest biomass in the form of 1 ogging residuals for use as energy wood. The prototype is presently undergoing developmental tests. Results are encou raging, indicating mechanical feasibility with prospects of working systems within the next several years. Papers presented before ASAE meetings are consldered to be the property ot th...

The renowned Australian entomologist Alexander J. Nicholson carried out a series of experiments in the 1950s with the intent of learning more about a sheep pest, the blowfly. The results presented here are driven by analyses of the data that Nicholson collected. The situation is of special interest because it involves a system that is nonlinear, has time lags and might be described as non-stati...

Dalam makalah ini, dikaji kestabilan model inang parasit Nicholson-Bailey dengan menggunakan fungsi pertumbuhan Hassel. Model digambarkan dalam bentuk persamaan beda non linier diskrit. Dari hasil analisis diperoleh tiga titik tetap yang kestabilannya ditentukan oleh tingkat reproduksi inang.
