Indian Forester, Vol 126, No 5 (2000), Pagination: 493-498Abstract
Joint Forest Management in a real sense began in Maharashtra from 1996-97 and 58 villages were included in the first instance under this plan. This has now increased to 602 villages. Financial assistance is provided by State Govt. in a phased manner for its various components. The micro-plans are prepared in consultation with the villagers. Total area covered at present is about 2 lakhs ha, under the protection of village committees. Corporate houses are also participating in several of its programmes. The progress is monitored at Circle and State levels. Documentation is done as it is likely to motivate the people. Training is being imported to Forestry staff at different levels. Village level workshops are also organized. Benefits have been noticed in the quality of forest mlmagement, moisture regime and better quality of grasses and some employment to the villagers. Future plans are to extend the scheme to the management of more than 181akhs ha, spread over 10,720 villages in a phased manner. When Govt. assistance shall be stopped, the scheme will be able to sustain itself from the forests' own resources and an initiative has been made by levying some nominal fees, etc. Naxalite infested areas are proposed to be included in the scheme.

In recent years the loadiag of timber on to trucks has become increasingly mechanised while loading by hand, a heavy, dangerous, time wasting and expensive operation hand correspondingly decreased. In this context the performance of the traxcavator, which is a caterpillar tractor fitted with wihch and loading attachment was studied in the Chajpur forests of H.P. The study reveals that the mechanise loading device performs the loading job much quicker and thereby reduces the cost of loading considerably. In view of the high risk and high energy consumption involved in manual loading this equipment has a promising future in mechanised logging operation.- Timber Transportation - A Comparative Study

The cost of transporation of wood from the forests to the consuming centres is the highest component in total logging cost constituting nearly 60-70% of it, in order to find out the comparative suitability, speed behaviour and economics over various types of roads of the trucks, tractors and the traditional bullock cart, a detailed study was conducted in the teak forests on N. Betul. (Production) Division of Madhya Pradesh. The traditional bullock cart was found to be economical upto a lead of 4 kms distance on unmetalled road. It was observed that the standard of road does not have significant impact on the speed of bullock cart as evident from the break even point of 4.25 kms in tar road. Under the present working condition the efficiency of bullock cart can be increased if the improvements suggested in the paper are taken up.- Energy Expenditure During Stump Area Operation

Systematic studies on the physiological aspect of logging has been initiated recently by the logging branch of F.R.I. So far, logging research was restricted in finding out the economic suitability of various tools and equipments and the consequent prediction of productivity. The present persuits economics in logging will bridge the gap and will enable us to identify the suitability of a method or an equipment in a more rational basis. Accordingly study was taken in the high elevation forests in the Chajpur area of Himachal Pradesh with the aim of determining the energy consumption of forest workers in various stump area operation. The study reveals that there is significant reduction in energy expenditure when maintenance of saws are done scientifically. It is observed that during felling and conversion of trees the raker saw (2 : 1) involves consumption of least energy provided the maintenance is done scientifically. Delimbing operation is the most strenuous component of stump area operation and there is scope for improvement of the existing handtools so that physiological workload is reduced.- A Study on Felling and Conversion of Pulpwood

A comparative study was designed and conducted to find out the best economic hand tool for felling, cross cutting, delimiting for the preparation of unbarked pulpwood billets. For these operations six type of saws including power chain saw were used in Bijnor Plantation Division of U.P. for felling and conveuion of Eucaiyplus hybrid. The Investigation on was carried out in two phases It was observed that under existing condition power chain saw is not economical for pulpwood harveoting. The best tool appears to be scientifically maintained peg tooth cross cut saw. It was also observed that scientific maintenance of saws increases the efficiency of the tool by 54% and consequently the production cost is substantially decresaed.- Study on Cutting of Sawlogs by Power Chain Saws in West Beiligal

In India Power Chain Saws have been introduced in recent years for felling and conversion of trees. These saws are presently imported from developed countries like Sweden, U.S.A, and W. Germany and consequently a number of models of these saws are available. It was felt necessary to investigate the relative suitability and economics of these commonly available power chain saws for a specific stump area operation. Accordingly a detailed time and cost was undertaken in the foothill forests of Kalimpong Division in West Bengal where power chain saws are being used in fairly extensive scale by professional operators sponsored by the forest development corporation of West Bengal. Three models viz Partner R-12 Poulan 245A and Mc Culloch ProMac 60 were compared for felling and conversion of miscellaneous softwood species for the preparation of plywood logs. The study concludes that Partner R-12 power chain saw is the most suitable equipment compared to the other two. The details of production economics, cutting speed and cost of operation have been derived and discussed in support of the inference drawn.- A Study of Transportation of Timber by Long Distance Conveyor Lasso-3S in West Bengal

The valuable inaccessible forests of North Bengal which virtually remained unex ploited over centuries are opened up now due to the introductiou of elaborate and efficient complex of aerial transportation units like the Lasso-3S. Long distance conveyor and Hinteregger all terrain skyline crane. The efficiency and cost studies were conducted on the Lasso-3S. Long distance conveyor working in Dhaper forests of Kalimpong Forest Division. The Lasso-3S ropeway is permanently installed over a span of 4.02 km and are feeded by two Hinteregger all terrain skyline cranes. The coat of aerial transportation of timber over the distance in calculated and found to be Rs. 93.34 per m3. It is observed that there is still a scope of increasing the efficiency of the machine by 23.43% which will ultimately reduce the coat of transportation to Rs. 46.67 per m3.- A Study on the Performance of Fri Skyline Crane in West Bengal

The FRI Long Distance Skyline Crane was designed by the Logging Branch of F.R.I. and Colleges and fabricated locally making use of all indigenous components. The machine was subjected to extensive field trial for uphill extraction of timber in the inaccessible hill forests of Darjeeling district of West Bengal for nearly a year. Thereafter a detailed time and cost study was conducted at Luleygaon to find out its suitability, efficiency and economics of operation. The machine has shown a promising result particularly in view of the fact that this was the maiden attempt of the branch in designing and fabrication of such an equipment. Apart from the advantages that are inherent in an indigenous machine the performance of this machine with regard to its hauling capacity, hourly working cost and the cost of aerial transportation of logs compares favourably with similar equipments imported from foreign countries. The time and cost study also identified the scope and areas of improvements in the existing machine.- Pulpwood Felling and Conversion by Different Felling Implements-a Comparative Study

In developed countries Power Chain Saws have almost replaced the other hand tools for felling and conversion of trees. It was considered necessary to investigate whether the Power Chain Saw holds the same position in India. A comparative study was designed and conducted to find out the best tool for felling, cross cutting, delimbing for the preparation of unbarked pulpwood billets. For these operations three tools vis., Cross Cut Saw, Bow Saw and Power Chain Saw were used in Bijnor Plantation Division of U.P. for felling and convertion of Eucalyptus hybird. It was observed that Power Chain Saw is not economical under Indian condition for pulpwood harvesting. The study has indicated that although the output per man hour may increase considerably along with consequent saving in manpower due to the introduction of Power Chain Saw, the cest per unit volume of unbarked pulpwood billets Would not be reduced.- Efficiency and Cost Studies of Hinteregger all Terrain Skyline Crane in West Bengal

The potentially valuable hill forests of Darjeellng District in West Bengal remained unexploited because of poor communication and transport facilities. With the introduction of modern logging equipments like gravity conveyor, All Terrain Skyline Crane, Lasso winches etc. the extraction of timber is now economically feasible from the inaccessible hilly areas. The efficiency and cost studies is conducted on Hinteregger All Terrain Skyline Crane at Dhapar in Mo block of Kalimpong Forest Division, The cost of transportation of wood per cu. metre for the span of 450 metres is calculated and found to be Rs. 36.68. The study has revealed that the machine is not being used at its full load capacity; the cost of transportation would have been much lower had the machine been worked at its rated capacity.- Deformation and Metamorphism in the Precambrians of Rajasthan

The varied lithological units of the Precambrian complex, represented by the Pre-Aravallis, Aravallis and Delhis, exhibit a set of complicated structural and metamorphic features that were the result of overprinting of at least four successive cycles of non-affine deformative movements, followed by later minor orogenic impulses spread over a long span of time. The Delhis are characterised by two sets of major folding movements giving rise to NNE-SSW (F3) and WNW-ESE (F4) structural trends, while the Aravallis are associated with two completely separate structural trends i.e. E-W (F1) and NW-SE (F2), which indicates that the tectonicity varied in space and also in time during the Delhi and Aravalli times. The fold-pattern in the Pre-Aravallis is the same as is noticed in the Aravallis.
The main metamorphic episodes in the Pre-Aravallis, Aravallis and Delhis, which were, sensu stricto, regional in nature, were coeval with the earlier phases of the major folding movements and were followed by dislocation and diaphthoresis in zones of shearing, thereby causing retrograde metamorphism in limited locales. The grade of regional metamorphism, in general, varies between lower greenschist facies to Upper amphibolite facies. The presence of granulites, at places, however, suggests higher temperature and pressure conditions prevailing at least locally. The thermal metamorphic effects in contact with basic and ultrabasic intrusives and with effusive acidic phases are very local.

The 2005 eruption of Barren Volcano was explosive and pulsative Strombolian type (15-30 seconds interval). A thick column of grey smoke along with red-hot pyroclasts was found ejecting out with rumbling sound from the crater. The eruption column of ash particles attained a height of more than 300 m, whereas larger pyroclasts were ejecting out to about 100 m above the crater. The assorted mixture of air fall tephra in the form of blocks, cinders, lapilli and spatter along with ash formed two cinder cones. Pyroclasts are of basaltic composition and show vitrophyric texture with phenocrysts of plagioclase, olivine and diopside set in a glassy groundmass. EPMA of the mineral phases shows that plagioclase phenocrysts are represented by anorthite (An 94.5) and bytownite (An8 1.6-89.0),whereas in the groundmass, feldspar microlites are labradorite (An57.3). Compositionally olivines are forsteritic (Fo72-79), and the clinopyroxenes as phenocrysts are diopside and clinopyroxenes in groundmass as pigeonite. Major oxide analyses of the bulk pyroclastics show that the basalts are high alumina basalt of Island Arc Tholeiitic (IAT) affinity Mineralogical as well as chemical similarities of these basalts with lavas of earlier eruptions from Barren Volcano suggests no major change in magmatic evolution with time in the inner arc setting of Andaman subduction complex.Keywords

This paper examines the adaptation of the ‘big data’ strategies in the developed capital markets and its effect on the efficiency of the capital markets. The big data strategy and algorithms use the power of high capacity computing to affect the high frequency trading which improves the efficiency in the market. However, high frequency trading also poses many regulatory challenges for the Security and Exchange Commission. Social media and microblogs affect the risk appetite of the investors. The sentiment and decision-making pattern of the investors are influenced by the continuous flows of the information through the social media which affects the capital markets.References
