Development of an Appropriate Rice-Based Biomass Gasifier as Source of Power for Farm Use  [PDF]
Alexis T. Belonio, Manuel Jose C. Regalado, Phoebe R. Castillo
Open Access Library Journal (OALib Journal) , 2018, DOI: 10.4236/oalib.1105054
Abstract:
An appropriate rice-based (ARB) biomass gasifier was designed and de-veloped for farmers’ use. The gasification properties of rice-based biomass were determined before doing the design. The gasifier was built using salvage petrol drums, metal bars and concrete as primary construction materials. It has a 30 cm-diameter reactor insulated with refractory cement. A 10 cm-o cross flow scrubber with 30 cm-thick packed-bed filter is used for conditioning the gas. The gas is converted to mechanical power with the use of a four-stroke-cycle, spark ignition engine commonly used by farmers. The gasifier was tested and underwent series of modifications and improvements. Performance test and evaluation showed that the gasifier performs satisfactorily as per design. Raw rice husk was found to have greater advantage as fuel for the gasifier than rice straw. It can drive sta-tionary agricultural machines such as a 4-in. pump, a 30-cm biomass chip-per, and a 20-cm rubber creeping mill. It can also power a 3-kWe AC gen-erator for lighting and a 60-Amp DC alternator for charging batteries. The entire system can be built at a cost of P90,000.00 (USD1 = PHP50) using local materials and skills. Analysis showed that the operating cost of the gasifier is only P94.15 per day. A savings o P244.94 per day can be derived against the use of purely gasoline fuel for the engine. Payback period is 1.22 years.
Einthoven: El hombre y su invento

Abstract: einthoven, a dutch physician, was awarded the nobel prize for physiology or medicine for his discovery of the mechanism of the electrocardiogram. he was born on may 21, 1860, in semarang, on the island of java. in 1878 entered the university of utrecht in the netherlands, as a medical student, where he also became a keen sportsman. in 1885, he was appointed professor of physiology at the university of leiden, where he began to work using first a capillary electrometer. later, einthoven invented a new galvanometer to generate electrocardiograms using a fine quartz string coated in silver and published his findings in 1901 and 1903. einthoven is remembered by most of his colleagues and clinical peers as a very modest person who was hospitable and honest. he died at the age of sixty seven (rev méd chile 2004; 132: 260-4)
El médico y los conflictos de intereses
Lama T,Alexis;
Revista médica de Chile , 2003, DOI: 10.4067/S0034-98872003001200015
Abstract: conflicts of interest are frequent in medical practice. they occur when a secondary interest unduly influences professional medical judgment, over and above the patients' benefit, his first real interest. most of these secondary interests come from particular businesses of the physicians or their relationships with the industry. they may become a threat to the confidence that is established in the patient-physician relationship or to the medical profession as a whole. these conflicts of interest vary in types and magnitude and are not recognized by physicians on most occasions. solutions are inevitably related to the honesty and integrity of each physician. due to the absence of specific national ethical references, it is necessary to discuss the issue and conclude recommendations that guide interns, residents, clinicians, researchers, medical educators, medical and scientific associations to resolve these types of conflicts (rev méd chile 2003; 131: 1463-8).
