  • Zeolite membranes on various supports such as filter paper, cotton fiber, and glass fiber filter were prepared by secondary growth hydrothermal synthesis. First, zeolite NaA (${\approx}0.5{\mu}m$) and silicalite-1 (${\approx}0.2{\mu}m$) crystals were synthesized as zeolite seed crystals, and they were attached to the surfaces of the supports via chemical bonding. Zeolite NaA or silicalite-1 membranes could be synthesized on the supports coated with the seed crystals. The prepared zeolite membranes were observed by scanning electron microscope and analyzed by X-ray diffraction.

  • Non-edible vegetable oils instead of edible vegetable oils as a substitute for diesel fuel are getting a renewed attention because of global reduction of green house gases and concerns for long-term food and energy security. Out of various non-edible vegetable oils, karanja, mahua, linseed, rubber seed and cotton seed oils are selected in this study. A brief review of recent works related to the application of the above five vegetable oils and its derivatives in CI engines is presented. The production technologies of biodiesel based on non-edible vegetable oils are introduced. Problems in vegetable oil or biodiesel fuelled CI engine are included. In addition, future works related to spray characteristics of non-edible vegetable oil or biodiesel from it are discussed. The biodiesel fuel, irrespective of the feedstock used, results in a decrease in the emission of hydrocardon (HC), carbon monoxide (CO), particulate matter (PM) and sulphur dioxide ($SO_2$). It is also said to be carbon neutral as it contributes no net carbon dioxide to the atmosphere. Only oxides of nitrogen (NOx) are reported to increase which is due to oxygen content in the biodiesel fuel. The systematic assessment of spray char-acteristics of neat vegetable oils and its blends, neat biodiesel and its blends f3r use as diesel engine fuels is required.

  • In order to find the effect of the storage time on the characteristics and sterol composition of the sesame seed, the characteristics, unsaponifiable matters, fractionation pattern of sterol and sterol compositions of 4-desmethylsterol on the sesame seed oil were analysed at the harvest time and after 56 months storage. The sample seed was kept in cotton bag within the natural dark store room. The oil content was decreased from 50.3g per 100g sesame seed at harvest time to 45.5g at 56 months stored. The acid value was increased sharply from 1.8 to 13.4 during the storage of sesame seed and iodine value was increased small, but saponification value and refractive index were hardly changed. The amount of unsaponifiables from 24.3mg to 20.9mg per gram on basis during storage time, and the 4,4-dimethylsterol and 4-monomethylsterol from unsaponifiables were decreased, otherwise, 4-desmethylsterol was increased. In the changes of sterol composition in the 4-desmethylsterol fraction from unsaponifiables, the compesterol and stigmasterol content were not nearly changed, otherwise, the sitosterol content was decreased from 51.0% to 48.2%, but the content of ${\Delta}^5-avenasterol$ was increased from 15.2 % to 18.4% during the storage of sesame seed within 56 months.

  • In this study the natural colorant was extracted from black bean seed coat in aqueous solution and used to dye silk and cotton fabrics. To obtain the optimal dyeing conditions it was examined at various dyeing condition (temperature, pH, time and liquor ratio). The dyeing behavior and the depths of shade which were evaluated in terms of K/S and CIELAB color difference values of the dyed and mordanted fabrics were also investigated. The dyeing fastness evaluated standard light and wash fastness tests. The obtained results were as follows ; The most K/S value of silk and cotton fabrics were obtained when the pH was 4.0 and 4.8, respectively and it increased slightly with dyeing time passes when the dyeing temperatures were at $40^{\circ}C$ and $60^{\circ}C$ but, it increased at $80^{\circ}C$. The color of silk fabrics changed from yellowish red to yellow at only Fe mordanting among various mordanting. Sn and Ti mordanting of silk fabric and only Ni mordanting of cotton fabric increased the $L^*$ values, but the others decreased. The light fastness of silk fabrics showed 4-6 grade without mordant, 4-5 grade with Al, 3-4 grade with Cu and Sn, and 2-3 grade with Fe as mordant, and that of cotton fabrics showed 1-2 grade without mordant, 2-3 grade with Fe, 2 grade with Cu, 1-2 grade with Al and Sn as mordants. All mordanting coluld not improve the light fastness of fabrics. Washing fastness(fade) of silk fabrics showed 2 grade without mordants and 2-3 grade with mordants and those of cotton fabrics showed 4 grade with Cu, 3 grade without mordant and with Al, Sn and Fe. All of the washing fastness(stain) of both fabrics showed 4-5 grade.

  • In this study we carried out to find suitable nutrient supplement of corncob as a main carbon source for bottle culture of oyster mushroom. Data from chemical analysis of Kapok seed cake(KP) treatment showed 20.2 of C/N ratio, $0.28g/cm^3$ of bulk density and 74.2% of porosity. Mushroom yield of KP treatment is 158g/bottle that is similar to control(150g/bottle). However, the price of KP is 400 won/kg that is cheaper than 550 won/kg of cotton seed cake(CS). The highest REV(relative feed value) also was observed KP treatment. A further study is required determine practical animal performance by feeding the corncob-based KP.

  • In the present study, an attempt was made to use FV (Fatty acid ratio & Villavecchia reaction) value determination as a reliable method for the detection and analysis of the adulteration of sesame oils. FV value was defined as fatty acid ratio, C18 : I + C18 : 2/C16 : ${\times}C18$ : 3, times modified Villavecchia-Suarez test value. Seventy-four sesame oils collected from markets were evaluated using this method. Only II among 74 collected sesame oils were found to be pure sesame oil by FV value determination. In 63 adulterated sesame oils, it was revealed 23 samples were adulterated soybean oil, to with rice bran oil, 10 with sesame dregs extract oil, 8 with perilla seed oil, 7 with corn oil, 3 with cotton seed oil, and 2 with rape seed oil.

  • Comparison of fruit bodies of Pleurotus ostreatus cultivar chunchu No .2 grown on the sawdust, rice straw and cotton waste substrates revealed differences in the pattern of differentiation of hyphal compartments. Required period for primordium induction of fruit bodies grown on sawdust substrate was 13 days. Physical structure shown as hardness of stipes grown on the sawdust substrate, fruit bodies were harden than control. Pileocystidia were well developed on the surface of pileus in the fruit body cultivated on rice straw. Microstructures of fruit body grown on the sawdust and cotton wastes substrates shown fast-discharge of basidiospore and sytoms ageing. Hyphae of fruit bodies formed on sawdust substrate had less stainable cytoplasmic material and many more vacuoles than hyphae of fruit bodies formed on synthetic substrate with 50% of pine sawdust, 30% of cotton seed hull and 20 of beet pulp(control).

  • The relative disappearance and rate of degradation of dry matter (DM) and neutral detergent fiber (NDF) of nine different feedstuffs were determined by simultaneously suspending groups of substrates, using the nylon bags, in the rumen of males of Sahiwal cattle and Nili-Ravi buffalo. The digestion kinetics of leguminous forages (Lucerne, berseem and cowpeas) and feed byproducts (cotton seed cake, wheat bran and wheat straw) did not differ between the two species. However, the DM and NDF digestibilities and rates of digestion of grasses and wheat straw were greater in buffalo than in cow bulls, indicating that buffaloes are better converters of poor quality roughages than are Sahiwal. The lag time for DM of grasses did not differ between these two species but the NDF lag time was lower in buffalo than in cows, indicating that both the rate and lag time of digestion may be reliable indicators for assessing the NDF quality.

  • Role of low degradable protein in milk production of early lactating Murrah buffaloes has been studied in relation to energy status of test animals. Replacement of conventional concentrate mixture with low degradable cotton seed cake resulted in appreciable changes in circulatory transaminases and phosphatase levels. The enzymes viz. glutamate oxaloacetate and glutamate pyruvate transaminase and alkaline phosphatases increased with feeding of said cake indicating stress on hepatic tissue. Animals seemed to overcome stress by feeding enhanced levels of same protein along with improved feed intake, body weight and milk production.
