The right to die: Its biomedical aspects

This article discussed the existence or non-existence of the right to die. Death has various facets, namely the biomedical,social,historical, moral and religious. Man has the right to live or not to be killed, but not the reciprocal right to die or to kill, although in borderline cases this is debatable. The right to die is executed by way of suicide and voluntary euthanasia. Suicide is committed due to hopelessness, shame or guilt feeling, terminal illness, loyalty to a dead person, and for political reasons. It can be performed by an individual, a pair (suicide pact), a family, a group or en masse. The medical profession should prevent all suicidal attempts and help the surviving victim, since it is its duty to prolong life and ameliorate suffering. Euthanasia is either positive or negative (not infrequently, and inaccurately, termed active or passive), voluntary or involuntary, direct orindirect, and by not implementing extraordinary or ordinary procedures in life saving. Reasons are put forward why euthanasia is condonded or condemned. The moral difference between the two forms of euthanasia are questioned by some serious ethicists. Contitions for negative euthanasia are presented if it is performed selectively, for which the demand is unfortunately real. key Words: righ to die-euthanasia-suicide-patient rights-bioethics.T.

The genetics of diabetes millitus

It is now clear that diabetes millitus is not a disease in classical sense but is genetically heterogeous froup of disorders whitch share glucose intolerance in common. Genetic heterogeity, the concept that diabetes can have many different causes, was first suggested by the existence of rare genetic syndomes with diabetes, etnic differences of clinical features, and genetic heterogeneity in animal models. This paper describes the background for genetic heterogeneity of diabetes mellitus which has major implications for the research and care of diabetic patients since the precise etiology, risk of complications and genetic counselling are likely to vary among these diggerent disorder that result in diabetes. Key words: diabetes mellitus-genetic heterogeneity-model of inheritance-genetic counselling-autoimmune process. Amhad H.

Sustainable Decentralized Rural Electrification : Perspectives With Special Reference To Indonesia

(Paper presented at the International Seminar for Sustainable Decentralized Rural Electrification, organized by the Agence de I'Environment et de la Maitrise de I'Energie, Paris, France, in Marrakech, Marocco, 13-17 November 1995.
As rural electrification concerns populations with lower income and dispersed over the country's territory with low demand, the costs are often higher than the revenues expected from the sales of elctricity, at least during the initial years. However, introducing rural electricity, also to isolated areas, is in the interest of many:households in need of a better standard of living, goverments striving to reach a proper economic balance between urban and rural areas and hence also to steam rural exodus, and international communities wishing to avoid global imbalances in population and wealth. In 1994 the total number of villages in Indonesia amounted to 60,344 of which electricity;according to the current plan a village electrifivation ratio of 100 percent will be reached in 2004. Due to Indonesia's geographic characteristics as an archipelago, not all villages will be connected to a grid, and about 2,800 villages will have to be electrified by decentralized systems. An attempt in made to look at some issues concerning sustainable decentralized rural electrification, involving socio-economic impacts, environmental concers, financial and organizational problems and also experience with a few decentralized rural electrification schemes. by. Abdul Kadir; Professor, University of Indonesia, Jakarta.

FABRICA TION OF FLANGE WINDOW FOR LA TEX INDUSTRY ELECTRON BEAM

Fabrication of flange window foff latex industry electron beam machine has been done. VWndowof Electron Beam Machine has function to pass through electron beam from the machine to the atmosphere. Since the inner of the machine is in a high vacuum condition, the window has to hold the atmospheric pressure and pass through electron beam with a little hindrance, so the energy lost can be minimized. Because of the window function, the flange is needed to stack on in the scanning construction. Besides that, the flenge has function as a holder so that the window is able to hold the atmosphere pressure. For this purpose, fabrication of flange will be done to fit on the window in the scanning hom. The type of flange to be made is intermediation flange. The flange is made of stainless steel with 12 mm of thickness, 200 mm of width, and 700 mm of length. The fabrication is done in the Electromechanical Utility with the existing machine and equipment tools.

Abstraction, not just mathematics, has its place in science as it does in art

Abstract Science?
Analysis as the Path to Abstraction
Mark Rothko paintingClick to Enlarge ImageA characteristic modus operandi in abstract art, from Russian constructivist times, has been the concentration on one or another component of the artistic whole. Issues of form—the center or the periphery, inclusion or exclusion, see-through or opaque, balance, color—are isolated. Ad Reinhardt’s beautiful all-red and all-black paintings are a fine example of this concentration. The contemplative process here can lead to an exploration of the emotional possibilities of just that formal element. One sees this motif at work in Klee’s abstract paintings, or in Rothko’s color fields (right). Roberto Bertoia, a colleague at Cornell, works out beautifully in small wood constructions the feelings of confinement, protection and communication (below right).
Robert Bertoia sculptureClick to Enlarge ImageOf course, science, from its Cartesian roots, has operated in just this way. If you want to understand something, take it apart, see how the pieces work, put it together (although too few people like to put things together …). Change only one variable at a time, if you can. If you want to see how a chemical reaction proceeds, write a mechanism, a sequence of elementary steps. Once the mechanism is recognized, have research programs develop on the pieces and extend the work. Taking things apart, as science does, is a move shared with abstract art. Roald Hoffmann.

The Molecular Basis of Size Differences

Size differences account for a great deal of the diversity found in the animal kingdom, but we still have much to learn about how sizes are programmed. Generally, the cells of different animals are comparable in size, and all animals begin as a single cell. This leaves the number of cells accumulated as the main determinant of animal size. We can reasonably expect the genes controlling cell number to be conserved among animals. So it seems that size-determining genes must be deployed in the elephant in such a way that it amasses several hundred thousand times more cells than the mouse. Which are these genes and how do they control size? I asked this question in a more experimentally tractable context: How do body parts of a single animal become different sizes? Fingers, toes, and ribs are sets of structures whose members are similar in form but differ in size. Although we know that Hox transcription factors specify the identity of individual fingers, toes, and ribs, little is known about how their individual sizes are programmed. Michael A. Crickmore.

Abstraction, not just mathematics, has its place in science as it does in art

Abstract Science?
a Japanese bottleClick to Enlarge ImageIs there an analogue in science to abstract art? A riposte might be, “Why should there be? Why ask science, so strongly tied to reality, to mimic the aesthetic games of the world of art?” Well, both art and science are created by human beings, and both are creative endeavors. So it might be interesting to look at any correspondences. No one-to-one mappings will be found, but let’s relax that criterion and search for non-literal, imaginative analogies. Roald H.offmann.
