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.

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).

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.

The algorithm is designed to improve the production of power lines, to forecast emergency situations and to recognize possible ecological risks.

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.

In majority of cases, a positive effect can be observed upon application of Laser Agnis-L01 in treatment regimen of bone fractures. Positive effect of the laser was observed in 66.7%, no change in 22.2% and negative effect in 11.1% of the rabbits in experiment. To accelerate healing of bone fractures, we recommended the following parameters in treatment regimen with Agnis L01: impulse power 1.5 W, impulse frequency 250 Hz, modulation frequency 50 Hz and duration of treatment episode 240 seconds, 5 squares of treatment, 1 dosage per day, 10 treatment episodes. The treatment should start from day 4 after occurrence of fracture. Efficacy of laser treatment depends on individual properties of animal. Treatment of bone fractures is complex, laser treatment could be an element of the treatment regimen.

There are five programming regions and regional development agencies. Regional development agencies must be involved in the administration process of the EU's prestructural funds. Research is done using Richard Rhod's classification of regions and the experience and practice of Great Britain in specially supported regions. The program of specially supported areas is the main financial instrument in Latvia, which promotes territorial development in depressive regions. The administrative territorial reform will make rectification in specially supported areas and in planning regions.

After regaining independence the agricultural production in Estonia has undergone a drastic decline. Due to the inadequate application of fertilizers and pesticides, the yield of field crops and grasslands has decreased 1-7 % per year. The balance of nitrogen in the arable soils is negative, particularly respecting fodder crops. At present, in Estonia most of grasslands are practically not fertilized, or they are fertilized in the last order. The amount of nitrogen removed with the yield of fodder crops, cereals and potato are by 45, 20 and 17 kg ha*[-1) higher, respectively, compared with the amounts of N applied to the soil with organic and mineral fertilizers, available for those crops. The effectiveness of nitrogen fertilizers depends largely on weather conditions during the vegetation period and is the lower, the higher is soil humus content. On gleyic and gley soils, whose humus content is higher, the efficiency of nitrogen fertilizers is 2-3 times lower and the agroecological and economic fertilization risks are higher. On sown grasslands, the efficiency of nitrogen fertilizers depends not so much on soil fertility as on soil water supply, humus content and grass sward type. With proper application of fertilizers, use of suitable plant species and varieties, it is possible to increase significantly not only the yield per unit area but also its nutritive value.

Production of cereals is mostly processed by operating the machinery. Operation of machinery influences the yield, i.e. also the income on one side, but it is also one of the biggest sources of expenses from the other side. Increasing the yearly operation time and amount of work of the machinery leads to decreasing costs per unit. Increasing the yearly amount of work is limited by agrotechnical terms. The crop yield depends on the time and duration of field work, and affects the farm income. The methods and formulae to prognosticate the averageoptimum yearly operation time of farm's machinery, i.e. also farm's cereal-growing area was composed by the author, concerning biological, technical and economical factors and relations, affecting cereal production. Farm profit and profitability were used as optimization criteria.
