  • Initial results of processing data from an experiment performed in November, 2005 are given. A microwave Doppler radar with a knife-like beam ($1.5^0$ - $24.5^0$) was installed on a helicopter. Measurements were made during a flight above the Gorky water storage basin. Power and Doppler spectra of the radar reflected signal were analyzed. The processing has shown that the algorithm developed for the retrieval of the slopes of rough water surface enables one to determine the direction of wave propagation and retrieve the variance of the wave slopes.

  • N crassa mutant strain nap showed reduced growth rate, decreased electric membrane potential, and elevated intracellular ATP content in comparison to the wild type. Blue light induced a hyperpolarization of the membrane potential in both strains. The analysis of oxidative and phosphorylation activities of mitochondria isolated from the two strains has revealed that nap utilized more efficient oxidative pathways. The higher intracellular ATP content in the nap was presumably due to impaired transport systems of the plasma membrane, and to a lesser extent to the functioning of the fully competent respiratory chain. The excess ATP possibly accounts for carotenoid accumulation in the mutant.

  • In organic Chinese cabbage fields, Commercial Bacillus thuringiensis products are used widely against diamond back moth, Plutella xylostella. We conducted the study to determine the effective spray-interval of commercialized B. thuringiensis against diamond back moth on Chinese cabbages. Chinese cabbage leaves were collected 0, 1, 2, 3, 6, 10days after treatment in first trial and 0, 2, 4, 7, 9, 11days after treatment. We compared the insecticidal property of sprayed B. thuringiensis and the density of it on surface of Chinese cabbages using collected leaves. The insecticidal property maintained high until nine days after commercial B. thuringiensis products sprayed.

  • This study was carried out to develop turning radius measuring method and device of using a DGPS speed sensor for agricultural tractors. The measurement system consisted of a DGPS speed sensor, a data acquisition device, a touch panel, a photo sensor, a radio modem and a notebook computer. Three methods were developed: average of turning speed-time method, integral of turning speed-time method, and speed-heading angular velocity method. Best method was average of turning speed-time method which could be used with a maximum error 2.7 cm.

  • In order to produce the colored cocoons we finalized the adequate amount of dyes throughout several trial and error experiments. The proper amount of each dye required for per 100 g of each colored cocoon turned out to be 150 mg of Rhodamine, 1560 mg of Thionin, 170 mg of Neutral red, and 200 mg of N-Blue, respectively. With this amount of dyes silkworms grew without physiological disorders. In order to produce colored cocoons, artificial diet composed mainly of mulberry leaves was fed to silkworms from the beginning of 5th instar, and subsequently fed with dye included diet from $4^{th}$ day of the 5th instar. This process resultantly produced colored silkworm body from the onset of feeding and subsequently colored cocoons and eggs. Nevertheless, the dye induced color was not inherited to next generation.
