Elasticity of demand of major root and tuber crop in the rural forest zone: implications for research for development
2010
Nkamleu, G.B. | Tchakoa, J. | Kenfack, J.P.
This paper analyses food consumption in rural households of forest zones. Based on a panel survey of 80 households in Cameroon, expenditure-elasticities of demand for roots and tubers are estimated and compared with those of other staples. Yam and cassava are the two most important root and tuber crops grown in Africa. The expenditure elasticity estimates for yam revealed that the domestic market potentials are high in forest zone for this crop, while in the case of cassava, it was established that the extent to which the potential market will be expanded, would depend on which degree the quality of the dry products can be improved

Changes in the quality of wheat flour bread after adding oat and buckwheat flour
2001
Skore, D. (Latvia Univ. of Agriculture, Jelgava (Latvia). Faculty of Food Technology. Dept. of Food Technology)
More and more people looking for healthy foods. Because researchers in nourishment to look for new possibilities in breadmaking. One of the possibilities is to substitute wheat flour by oat or buckwheat flour in bread products. Bread quality is characterized by sensory properties: taste, smell, flavour and texture. Hardiness, elasticity and gumminess are important indices of bread texture. The purpose of our work is to determine the changes in the bread texture of mix flour sample. Samples were prepared to substitute wheat at 10% and 15% or by at 10% and 25%. The wheat flour was used as a control. The experiments were made in the pilot Laboratory of I.A.T.A. in Spain, using AACC methods. Output data show that substitution buckwheat flour has improved the texture of bread, but substitution of oat flour has impaired the properties of texture.

2001
Akerfelds, I. (Latvia Univ. of Agriculture, Jelgava (Latvia). Faculty of Forestry. Dept. of Wood Processing)
A questionnaire related to the wood drying was carried out among wood processing enterprises in Latvia to clarify the main problems and possible differences depending on production capacity and products. Deformation (twist, bow, spring, cupping etc.) during the kiln drying has been identified as the most important problem for all enterprises. Many problems are related to the product area as very often improper drying technology or incorrect drying schedule is used. Others are connected to the organization and control of drying process - optimisation of the drying schedule, energy consumption, kiln control unit, maintenance of measuring equipment, MC measurement, quality control during drying. There is a difference between softwood and hardwood drying in the product and sales area. Considerably more problems are recognized in hardwood drying (hardwood is often used in furniture production and has higher quality demands).

2001
Medne, R. (Latvia Univ. of Agriculture, Jelgava (Latvia). Inst. of Food and Environmental Hygiene)
Salmon (Salmo salar L.) is grown and released in the estuaries in Latvia from which it goes to the feeding areas in the Baltic Sea. The research summaries data about clinical characteristics of fin necrosis and its prevalence in Latvian hatcheries before the smolt stage (complicated physiological, biochemical and morphophysiological changes resulting in migration flight). Clinically expressed fin necrosis was observed in 92.7-97.4% cases.

2001
Voicehovics, J. (Latvia Univ. of Agriculture, Jelgava (Latvia). Faculty of Rural Engineering. Dept. of Architecture and Building)
To investigate flood and hydraulic parameters of the river, the hydraulic models of the river Daugava near Jekabpils have been built at the Rural Engineering Faculty of the Latvia University of Agriculture and at the Research Scientific Institute of Water Managmenet and Land. Several possible solutions have bee proposed as a results of these investigations, though only the most effective and economically acceptable variant should be selected.
