Cost Of Bread Making In Central Samsun And An Economic Analysis Of The Factors Affecting Bread Prices, Hüseyi̇n Avni̇ Ci̇nemre, Mehmet Bozoğlu
Turkish Journal of Agriculture and Forestry
Most of the bread making units in the central district of the province of Samsun are small-scale and have so-called "black-oven" technology. On average, 500 kg of flour is processed daily in a bakery and in doing so only 37.3 percent of the total daily capacity of the bakery is utilized. Bread sold at kiosks, small grocery stores and in markets makes up 62.5 percent of total bread sales. The rest is sold directly by the production units. The production cost of a 250 gr loaf at bakeries is 12,848 TL and this figure reaches 15,098 TL when the marketing …

Turkish Journal of Agriculture and Forestry
This study was carried out on the natural range and meadows of Atatürk University in Erzurum, 1996. Recorded species in the study were separated into 16 grasses, 16 legumes and 60 other families. High percentages of the ungrazed species (approximately % 60) indicate that the rangelands have seriously been degrated. In chemical analysis, grasses had the highest crude cellulose content, while legumes had the highest crude protein content, and legumes and other families had the highest mineral element content. In conclusion some wild species on the district rangelands could successfully be utilized in the range improvement.

The method used in transportation of raw forest products can be performed in two phases. The first phase is called " the minor transportation" which is the extraction and hauling of the logs from the felling areas to the landings and intermediate depots. The second phase is "the major transportation". This phase covers the hauling operation from landings and intermediate depots to the log yards or the mill yards. The forestry transportation of harvested woods from compartments is the most difficult and the most expensive operation. Since forests are generally located on high and steep slopes of mountainous area in …

Analysis Of Binomial Data Obtained From Plant-Tissue-Culture Studiesusing Generalized Linear Models, M. Zi̇ya Firat, Ahmet Onay
Turkish Journal of Biology
In biology, the objective of research scientists is to gain an understanding of biological rela-tionships through experimentation. Statistical analyses are an essential part of biological research. Statistical methods used in biological research range from the very simple to the extremely complex. Consequently, caution should be taken when selecting an appropriate statistical method. Data obtained from plant-cell and tissue-culture studies can generally be placed into one of two or more groups. In other words, a dependent variable consists of placing an observation into a category. The purpose of this paper was to present statistical methods suitable for the analysis of binomial …
