  • The Albuginales (Oomycetes) consist of obligate biotrophic pathogens, none of which is culturable on artificial media. This group causes white blister rust disease in diverse angiosperm plants, including many economically important crops such as sunflower, horseradish, rape, radish, spinach, and wasabi. Recent advances in molecular phylogenetic tools and findings of new morphological characters have advanced our knowledge on their diversity, evolution, and systematics. This review introduces the white blister rusts and discusses recent innovations resulting from studies on Albuginales.

  • Soybean and rape seed are common feedstocks for biodiesel product ion in USA and Europe, respectively. On the other hand, South Eastern countries like Malaysia and Indonesia have surplus palm crops. However due to substantial amount of saturated fats in palm, the palm biodiesel has poor low temperature properties. To improve the low temperature flow properties as biodiesel, the dependence of the cold filter plugging point (CFPP) on the fatty acid compositions was examined. Two different kinds of biodiesels, palm and soybean biodiesels, were blended with the different volume ratios. And the low temperature flow properties of 0.5%, 1%, and 5% biodiesel in diesel blend fuels was tested. The decrease of CFPP was not observed for BD1 with Palm BD. Also, WDI test didn't exceed in the range of 4oC by the mixing of Palm BD upto 5% in commercial diesels.

  • Quality of industrial crops is considered to have three categories : the nutritional value, functional value, shape and appearance. The frame of this article are composed of five section : major oil crops, sesame, perilla, peanut, rape seed, and medicinals. The authors are reviewed and discussed on the current status and prospects of the quality evaluation and researches in industrial crops to provide and refers the condensed informations on the their quality.

  • Performance tests of small diesel engine were carried out, using the blend fuel oil as the substitute fuel oil and the following results were obtained. (1) The character at the blend oil as substitute fuel for small diesel engine was examined. (2) In the case of operating small diesel engine with blend oil, the exhaust gas volume increases at 8% in comparison with diesel oil. (3) In the case of operating small diesel engine with blend oil, the fuel consumption Increases at 3% in comparison with diesel oil. (4) In the brake thermal efficiency, blend oil is similar to diesel oil.

  • Studies on protein and antinutritional factors of rapeseeds are ncessary for effective utiliza-tion of defatted rapeseed meal. Proteins were extracted from seeds of several species of rape-seeds and analyzed by SDS-PAGE and the contents of glucosinolate and phytate were determi-ned. One percent solution extraction and extraction yield was relatively higherfor B. campestris and B. juncea than for other species. SDS-PAGE revealed that rapeseeds of most species were rich in low molecular weight proteins and that in particular the roteins of B. napus var. Halla and B. juncea were composed of simpler subunits as compared with other species. The content of glucosinolate was around 10mg/g of defatted meal for B. juncea however for var. Halla it was 7.26mg/g of defatted meal and 0.46mg/g of protein concentrate which were the lowest values. The level of phytate was between 2.7 and 4.6% for all species tested. Our results indicate thT B, napus var. Halla is the desired species for the utilization of rapeseed proteins.

  • Compared with ordinary varieties, the cold resistant lines were heavy in fresh weight of seedling, low in stalk elongation. Their leaf-types were complete runner types, and they were high in wintering rate, and were abundant in the branch number and in pod numbers per branch. They were high in the seed yield.

  • The level of serum cholesterol was successively determined for 4 weeks after the basic diet feeding for 8 weeks in the rabbits. It was observed that the individual serum cholesterol levels were highly elevated by the oral administration of cholesterol for 18 days, and then the rabbit were fed by sesame and rape seed oils for 11 weeks to survey the effect of the oils which was playing a role of decreasing factor for serum cholesterol values. The results were obtained as follows ; 1. The rabbit's serum cholesterol level was 128±29.0mg/dl in average, it was higher in female (162±50.6) than male(95±17.6). 2. It can be possible elevating experimentally the level of serum cholesterol by the cholesterol administration per os. 3. There were significant effect of the vegetable oils to decrease the experimental hypercholesteremia in the rabbits.

Effect on growth was in order of OM>OM . NPK interaction> NPK . active carbon and Mg were not effective OM . NPK interaction effect was negative on leaf width and root dry matter yield. OM and OM . NPK interaction were most effective on rhizome growth. Their effect did not change the ratio of growth rates between aerial part and rhizome but change that between aerial part and root. Leaf width was most sensitive to the treatments.

  • This study explores the relationship between attitudes toward abortion and such variables as age, education, religion, working, family income, son preference, and abortion experience. Questions are asked to see whether or not respondents think it should be possible to obtain legal abortion in nine circumcestances. Logit analysis is executed to see the relationship between abortion attitudes and explanatory variables for all respondents and then for women with abortion experience and for those without. Women with abortion experience are more likely to favor abortion than those without the experience. Catholics show tendency to oppose to legalized abortion compared to women with no religion. Women who show higher son preference are more likely to oppose to abortion in case of pregnancy by rape. Women who are working then to show favorable attitudes toward abortion in case of women who want no more child. Women who have low income and abortion experience have than young women. The more educated women show the more favorable attitudes toward abortion.

  • The purpose of this paper is to show how psychopaths' psychological factors are expressed on the characters' visual styles in the make-up coordination of slasher films. Psychopath is an ordinary person who has suffered some terrible trauma (humiliation, the death of a loved one, rape, psychological abuse), and features a disorder that consists of multiple components ranging on the emotional, interpersonal, and behavioral spectrum. Slasher films are sub genre of horror films that psychopathy characters, namely, Leather Face, Michael Myers, Jason Voorhees, Kenny Hampson, Harry Warden, Freddy Kruger and Billy kill the unfamiliar victims by cruel weapons with mercilessly. Their aesthetic characteristics of make-up coordination were shown in concealment, cruelty and suggestion. The concealment was presented by killers' masks, the cruelty was represented by their weapons, and the suggestion, especially space-time and status was depicted by their garments.
