A prospective surveillance programme for patients with longstanding (> = 8 years), extensive (> = splenic flexure) ulcerative colitis was undertaken between 1978 and 1990. It comprised annual colonoscopy with pancolonic biopsy. One hundred and sixty patients were entered into the programme and had 739 colonoscopies (4.6 colonoscopies per patient; 709 patient years follow up). Eight eight per ce...

In this study, the performance of a single cylinder four stroke direct injection (DI) diesel engine is analyzed in the light of first law of thermodynamics. An energy balance study is carried out to quantify the various losses associated with diesel engine processes on the basis of experimental performance and emission data. The engine was fuelled with normal diesel and Jatropha Methyl Ester (J...

Simple models for Earth's climate sensitivity (i.e. its temperature response to radiative forcing) are developed by combining the time-tested idealization of one-dimensional radiative-convective equilibrium (RCE) with simple yet quantitatively reasonable CO2 forcing and water vapor feedback. Along way, we introduce key paradigms including emission level approximation, forcing-feedback decomposi...

Communication is the science of “reliable” transfer of information between two parties, in the sense that the information reaches the intended party with as few errors as possible. Modern wireless systems have many interfering sources that hinder reliable communication. The performance of receivers severely deteriorates in the presence of unknown or unaccounted interference. The goal of a recei...

The topic of consistency tariffs in the electric power industry is investigated, issues imbalance course state regulation prices (tariffs) are considered. regulatory instruments that allow regulators to maintain current balance analyzed. Taking into account limitations currently existing for regulating price imbalances industry, it proposed additionally introduce new information and compensator...
