Comparison of forage wagon PÖTTINGER JUMBO 6600 and KEMPER CARGO 9000 in primary agricultural enterprises.

The aim of this thesis bachelor is a comparsion of two forage wagons Pöttinger Jumbo 6600 and Kemper Cargo 9000 and their efficiency in the harvesting silage, hay and straw.Evaluate the percentages of cut lengths of representation, depending on wear blades. Determines the basic performance, fixed and variable costs of harvesting. To a solution methodology was based on his own observations, information obtained from owners and specialized literature

Production and offer of regional and organic products in South Bohemia region and in county town

Organic food is a food product that is obtained from organic products and a limited amount of authorized additives defined technological process according to special regulation and the control regimen. Regional foods are due to short transport distances much fresher than food that has circulated for a long time. Regional foods tend therefore usually taste better and more valuable nutritional properties. Equally important is the fact that the closer the food to the consumer, the less loaded environment during transportation. The aim of the thesis is to evaluate the structure offers regional food and organic food producers to seek their districts Prachatice, and Strakonice Czech Budejovice. When evaluating the questionnaires, it was found that two-thirds of respondents regularly buy organic or regional food. Most often it is bought at a store in a specialized department.Most of the respondents to pay extra for regional food for a month for her to spend in the range of 200 to 500 CZK

Tapered Optical Fiber Sensor for Detection of pH in Microscopic Volumes

A compact and robust tapered optical fiber microsensor is presented for detection of pH in a range from 5.8 to 7.5 in sub-microliter volumes. The sensor is based on a pH transducer 8- hydroxypyrene-1,3,6-trisulfonic acid trisodium salt immobilized in a xerogel matrix onto the tip of a optical fiber taper with a tip diameter below 20 mm. The sol-gel method and two silicon alkoxides is used for preparing the matrix. A ratio of the fluorescence emission intensities measured at 518 nm after the excitation at 400 and 450 nm is used for evaluating the sensor response to pH. This ratiometric approach enables to reduce effects of ambient light, bleaching of the sensitive layer and geometry of the probe to the fluorescence signal and achieve the resolution of about 0.07 pH units
