Air Resistance

Motion of particles with air resistance (e.g. horizontal and inclined throwing) plays an important role in many technological processes in agriculture, wood industry and several other fields. Although, the basic equation of motion of this problem is well known, however, the solutions for practical applications are not sufficient. In this article working diagrams were developed for quick estimation of the throwing distance and the terminal velocity. Approximate solution procedures are presented in closed form with acceptable error. The working diagrams provide with arbitrary initial conditions in dimensionless form of general validity.

Planning Models

Input -output analysis is being widely used in developing countries for planning purposes. For a given level of final demand, input-output analysis allows us to project the required level of gross output to ensure consistency of plan. These projections are made on the assumption that the existing production structure is optimal and it implies that an increase in demand will be met through the expansion of domestic output even when it can be satisfied through an increase in imports. On the other hand, according to the semi-input-output method, we do not have to increase the output of international sectors in order to meet the increase in demand because the level and composition of these activities should be determined by comparative- cost considerations. These are the only national sectors in which output must increase in order to avoid shortage. The semi-input -output method has been such a useful and important contribution, yet, regrettably, its influence on the planning models had been rather limited.

Looking Back

Looking back on the last quarter of the 20th century, we see that the most striking changes in forest management have come about following large and frequent catastrophes. Management– concerned solely with wood production in former times – is oriented more towards retaining stability of the stands nowadays. In addition, the aspect of tending and improving the environment continues to gain ground. The growing gap between expenditure and profit is particularly acute in Glarner mountain forest areas. The extension of promotional silvicultural measures, which widely determines today's management, is to be seen as a logical consequence.

Archive Material

Evaluation of archive material from southwest Rhineland, Germany,has provided new knowledge on the development of forests in the 18th century. The society of those times had three different main requirements, which called for three different types of forest; for wood production, agriculture and hunting. But both landed gentry and the community as a whole were interested in maximising the use of the forest. It is therefore not accurate to conclude that wood production was only in the interest of the landowners and agriculture in the interest of the rest of the community. In addition, the different types of forest were subject to mutual dependence because changing one parameter meant that the balance governing wood production,grazing and arable areas, as well as habitat for game,also shifted. These interests, both divergent and common, of the population as a whole lead to the conclusion that forestry development was a highly political issue, and that the influence of the non-owning part of the population was greater than previously thought.

Coppice With Standards

Coppice with standards and coppice forests are the result of silvicultural systems widely applied until the mid-twentieth century, mainly for fuel production. Similar to energy plantations in Scandinavia and Germany the above-mentioned systems are characterised by a short rotation. The present paper tries to show that, owing to efficient logging methods, energy wood can be produced from coppice and coppice with standards forests so cheaply that it proves to be highly competitive compared to oil. The economic value of coppice and coppice with standards was calculated on the basis of models and compared to high forest cultivation. Contrary to high forests, the coppice with standards system is cost-covering on poor, well developed and easily accessible sites.

In the years since 2000, the authorities in charge of forests in canton Vaud have made some substantial changes as a reaction to the political decisions arising from the Swiss Forest Programme and the projected revision of the Federal forestry Law, as well as to the deterioration of the economic situation in forestry enterprises. This article gives a survey of the directions taken. Thus the canton recognises the primordial role of wood production as a driving force behind the creation of a multifunctional forest. The Service for Forests, Wildlife and Nature has invested a great deal in planning, and has redefined the management plan to be an instrument intended for forest owners and forest managers. The canton has innovated by introducing forestry groups and a scheme of equalisation of forestry costs between communes. Hence the conception of forestry management in canton Vaud is resolutely that of a multifunctional natural heritage.

Insight Into

Thirty cut flower businesses were surveyed in 1997 to examine the production structure and main problems of export-oriented contract growing in Turkey. The survey was conducted in Antalya province, which is the center of export-oriented cut flower production in Turkey. The results of the research provided insight into how Turkish cut flower-contracted growers were managing some of the key areas of their operations. The study also provided the opportunity for growers to highlight their concerns about contract growing for export-oriented cut flower production. The survey showed that contract growers do not use specific performance indicators relevant to cut flower production. The product price received by the contract growers was determined by the export companies. These export companies receive flowers from growers mainly on consignment. After exporting the products, exporters periodically pay the grower, subtracting a commission for their services and other marketing expenses. Contract growers are essentially price takers in the transactions. The business procedure from production to price setting and marketing was not in the hands of the contract growers. Therefore, the trading risks are essentially borne by the contract growers. The main concerns raised by contract growers were the current consignment system, cost of the plant materials, and the late payment for the sold products.
