Animalia Humorosum: Aesop's animal fables made more believable with a modern twist
No full textThere is much that is unusual about this 8½” square booklet of 28 pages followed by two pages of advertisements for other books by Óla. For starters, the pages are purple with light-colored typeface and cutout colored characters in partial-page illustrations. The T of C uses superscript to indicate page numbers for the twelve fables. That same page clarifies that Ólafia L. Óla is a pseudonym for V. Subhash. In TH, the hare, not the tortoise, challenges to a race upon no provocation. The author turns this tale into the more usual “Rabbit Races the Hedgehog,” famous among Grimm’s fairytales. Every one of the species looks the same to the superficial hare. In LM, after the mouse frees the lion, the hungry lion eats the mouse. “Steer clear of known dangers.” DW is told just as in the tradition. “Better die on your feet than live on your knees.” In TB, the second traveler takes off his socks; the smell of them revolts the bear, who departs. What did the bear whisper to him? “Tell that fellow that trees offer no safety because bears are good climbers.” The ox makes up a snake friend to worry the dog out of his manger. A passing hunter saves the shepherd boy attacked by a real wolf. The mice do manage to get a bell around the cat’s neck by having it ready around their hole when the cat pokes in its head. Two foxes jump for grapes. One reacts according to the tradition. The other says the effort has been stupid. “We are foxes. We don’t eat grapes. Let’s go and catch some rabbits.” One of two crows suggests the traditional pebble approach. The other says that will take too much time and too many pebbles and will dirty the water. He manages to knock over the pitcher and they can drink both from the water spilled and the water still in the overturned pitcher. The owner of the golden goose eventually stops reading his mail, misses paying taxes, loses his property, and has to give up the goose as compensation for the unpaid taxes. The wolf escapes the lambskin and never comes back. The crow removes the doughnut from his mouth and tells the fox to move along.Ólafia L. Óla (V. Subhash
On Public Capital Investment and Economic Growth in Illinois
No full textThe present paper was written as an analysis of the proposed capital budget plan which is being considered by the State of Illinois and which has been a major item on the political agenda in the state for well approximately two years. In the spring of 2008, Southern Illinois University President Glenn Poshard asked Dr. Subhash C. Sharma of the Department of Economics at Southern Illinois University Carbondale to do an analysis of the proposed capital improvements plan which was being advocated by then Governor Rod Blagojevich and being considered by the Illinois General Assembly. The plan would make a major investment in infrastructure improvements in the state, and it would have been the first major capital plan to pass the General Assembly in almost a decade. It follows in the tradition of two other major capital improvements bills advocated by earlier Governors and passed by the Illinois General Assembly. In 1985 under the leadership of Governor James R. Thompson, the state passed the Build Illinois Plan, which claimed at the time to be the largest public works project in the state’s history. It was funded at 12 billion total. The current Illinois Works plan would follow in the footsteps of those two prior major investments made in infrastructure by the people of Illinois if it were to be approved. The plan is still being considered by the Illinois General Assembly, and this proposal or something like it will be one of the major items for consideration by the new Governor Pat Quinn and his administration

A suitable method for journal bearing wear measurement
No full textPurpose – Ideally, there is no wear in hydrodynamic lubrication regime. A small amount of wear occurs during start and stop of the machines and the amount of wear is so small that it is difficult to measure with accuracy. Various wear measuring techniques have been used where out-of-roundness was found to be the most reliable method of measuring small wear quantities in journal bearings. This technique was further developed to achieve higher accuracy in measuring small wear quantities. The method proved to be reliable as well as inexpensive. The paper aims to discuss these issues. Design/methodology/approach – In an experimental study, the effect of antiwear additives was studied on journal bearings lubricated with oil containing solid contaminants. The test duration was too long and the wear quantities achieved were too small. To minimise the test duration, short tests of about 90 min duration were conducted and wear was measured recording changes in variety of parameters related to weight, geometry and wear debris. The out-of-roundness was found to be the most effective method. This method was further refined by enlarging the out-of-roundness traces on a photocopier. The method was proved to be reliable and inexpensive. Findings – Study revealed that the most commonly used wear measurement techniques such as weight loss, roughness changes and change in particle count were not adequate for measuring small wear quantities in journal bearings. Out-of-roundness method with some refinements was found to be one of the most reliable methods for measuring small wear quantities in journal bearings working in hydrodynamic lubrication regime. By enlarging the out-of-roundness traces and determining the worn area of the bearing cross-section, weight loss in bearings was calculated, which was repeatable and reliable. Research limitations/implications – This research is a basic in nature where a rudimentary solution has been developed for measuring small wear quantities in rotary devices such as journal bearings. The method requires enlarging traces on a photocopier and determining the shape of the worn area on an out-of-roundness trace on a transparency, which is a simple but a crude method. This may require an automated procedure to determine the weight loss from the out-of-roundness traces directly. This method can be very useful in reducing test duration and measuring wear quantities with higher precision in situations where wear quantities are very small. Practical implications – This research provides a reliable method of measuring wear of circular geometry. The Talyrond equipment used for measuring the change in out-of-roundness due to wear of bearings indicates that this equipment has high potential to be used as a wear measuring device also. Measurement of weight loss from the traces is an enhanced capability of this equipment and this research may lead to the development of a modified version of Talyrond type of equipment for wear measurements in circular machine components. Originality/value – Wear measurement in hydrodynamic bearings requires long duration tests to achieve adequate wear quantities. Out-of-roundness is one of the geometrical parameters that changes with progression of wear in a circular shape components. Thus, out-of-roundness is found to be an effective wear measuring parameter that relates to change in geometry. Method of increasing the sensitivity and enlargement of out-of-roundness traces is original work through which area of worn cross-section can be determined and weight loss can be derived for materials of known density with higher precision
Impacts of Watershed Development Programmes: Experiences and Evidences from Tamil Nadu
No full textThe overall performance of watershed development programmes has been examined in the state of Tamil Nadu. The impacts of major watershed development programmes have been outlined in terms of biophysical impacts, environmental impacts, socio-economic impacts and overall economic impacts. It is pointed out that the watershed development activities have made significant positive impacts on various biophysical aspects such as soil and water conservation, soil fertility, soil and water erosion in cropped area, changes in cropping pattern, cropping intensity, production and productivity of crops. Watershed development activities have shown significant positive impacts on water table, perenniality of water in wells, water availability for cattle and other domestic uses, etc. The overall economic impacts have been evaluated in terms of NPV, IRR and BCR. The peoples’ participation in watershed development activities has been found satisfactory but the optimal level is yet to be achieved. Training of farmers has been found effective in disseminating technical knowledge. According to the study, the future strategy should be the movement towards a balanced approach of matching the supply-driven menu with a set of demand-driven activities. Peoples’ participation, involvement of Panchayati Raj Institutions, local user groups and NGOs along side institutional support from different levels, viz. the Union Government, the state, the district and block levels should be ensured to make the programme more participatory, interactive and cost-effective. Convergence of various rural development programmes around the watershed could be ensured to promote holistic development of watersheds. For its continued success, the programme, should be economically efficient, financially viable, technically feasible and socially acceptable while ensuring equity. For, sustainable development, regular and routine monitoring of environmental parameters is important as environmental enhancement increases the credibility and acceptability of the programme.Agricultural and Food Policy,

Effects of solid contaminants on journal bearing performance
No full textThe presence of solid contaminants in the oil lubricating a bearing can result in excessive wear and hence reduced life. The details of an experimental study in progress are reported in this paper. This includes a concise literature review, the experimental strategies to be adopted in investigating the role of different additives in wear prevention in journal bearings and minimum oil film thickness in their lubricated contact. A computer code has also been developed to predict minimum oil film thickness and to compare it with the values measured experimentally
Institutional Vacuum in Sardar-Sarovar Project: Framing ‘Rules-of-the-Game’
No full textFew large irrigation projects in India have been as elaborately planned as the Sardar- Sarovar Project (SSP), incorporating as it did the lessons of decades of irrigation project design and management. The project was to blaze a new trail in farmer-participatory irrigation project design and management with water user associations (WUAs) building their own distribution systems. However, as it unfolds, the institutional reality of the project is seen to be vastly different from its plans. If SSP is to chart a different course from scores of earlier large irrigationprojects, it must invent and put into place new rules of the irrigation management game.Length: pp.95-106Irrigation programsRiver basinsGroundwater irrigationSurface irrigationWater users associationsWater allocation
