AbstractA pre-economic feasibility study was undertaken to determine the potential of cereal straw for industrial utilization in Minnesota. Specifically, utilizing straw for pulp and paper manufacture was of interest. The availability of cereal straw fiber supplies at various locations across the state of Minnesota, along with pre-processing issues such as transportation, harvesting, handling, and storage, are discussed and priced. The greatest economic advantage of straw for industrial use appears to be the low cost of the raw material compared to traditional raw materials. This also provides an excellent opportunity for additional income for farmers. The methodology and information provided here should be helpful in evaluating the feasibility of utilizing straw for other industrial purposes in other parts of the world. However, in some Third World countries, long-standing on-farm, traditional uses of cereal straws for fuel, fiber, and animal feed may limit their availability for industrial utilization.

The forest tree species that are widely grown to produce pulp and paper raw materials are Acacia spp. and Eucalyptus spp. One alternative species is binuang bini (Octomeles sumatrana) which can be developed for plantations. To maintain high seed viability, it is necessary to know the handling of seeds and control of seed-borne diseases during storage. The purpose of this study was to determine the method of the effective technique to control the seed-borne diseases of binuang bini during seed storage. The techniques for Seed disease kontrol methods in seed storage are carried out using chemical and natural fungicide. The results showed that the pure live seed was influenced by a single factor of fungicide and storage room, interactions between fungicides and storage room, interactions between fungicides and storage periods as well as interactions between fungicides and storage space and storage periods. Seed handling of binuang bini can be conducted effectively and efficiently by storing the seed in refrigerator for 3 months without using fungicides, but it will be better if the seed is given benomil fungicide and stored in airconditioned room (temperature of 18℃-20℃ and relative humidity of 50%-60 %).

Abstract Established applicability of biocomposites in the field of automotive, construction and structural industries has led to a hope to utilize them in the near future for further applications such as food packaging and lightweight coatings. Due to their global abundance, natural fibers and starch have been the most widely tested and used raw materials for use as the bio-composite reinforcements. Here in this work, composites based on corn starch (CS) and vetiver cellulose fibers (VCF) are fabricated using the solution casting method. Alpha-cellulose was synthesized from the vetiver roots post converted into nano-cellulose using the ball milling. Various compositions of 0%, 5%, 10%, 15% and 20% (by weight) of this α-cellulose were introduced as the reinforcement to commercially available corn starch matrix. Tensile tests for the fabricated composites were done in accordance with the American Standard for Testing and Materials standard procedure. Crystallinity and failure morphology of the composites was studied using the X-Ray Diffraction techniques and scanning electron microscopy, respectively. Water absorption capacity test, Fourier-transform infrared spectroscopy analysis, and determination of contact angle of the films were also done to evaluate the film properties. Results reveal that the incorporation of vetiver cellulose fiber in the starch enhances the mechanical properties of bio-composites. Also, the water absorption capacity and the contact angle decreased and increased, respectively; thereby predicting the composites application as a lightweight food packaging material.

ABSTRACTThere is a considerable excitement in the space community about the possibility of performing useful missions in space using vehicles that are much smaller in size than current spacecrafts. Lower cost and new type of missions made of this small satellite very attractive for future missions. Spacecraft in the mass range of 1 to 10 kilograms are often referred to as “nanosatellites”. However, the suite of useful missions for nanosatellite is limited by the dearth of space components of suitable scale. Present day nanosatellites are often drifting, uncontrolled packages of instrumentation of very limited capability. The vital subsystem functions of propulsion, power conversion and storage, attitude control, attitude sensing, data storage, command and data handling, and telemetry, tracking and control, are not well supported by these components availability of a number of small, low-cost nanosatellite components in these subsystem areas. This paper introduces the advances on applications based on piezoelectric transformers for nanosatellites.

Practicability of the use of biofortified sweet pepper of Zoloto Skifov variety and pumpkins of Sviten variety for processing by freezing is proved. The test samples were grown using a liquid, organic, environmentally friendly fertilizers “Riverm” (control – vegetables that were grown using standard technology). Vegetables were frozen at –23 °C after preconditioning and packaging. Storage of finished products was at –18 °C for 6 months. The research found that during the freezing and storage of vegetables gradual loss of sugars is occurred. Biofortified frozen pepper at 6-th month of storage contains 87.9 % of total initial sugar, biofortified frozen pumpkin – 59.5 %. Test samples of peppers and pumpkins after storage are more valuable for the sugar content than the controls. Changes of pectin amount were observeded during the freezing and storage of samples. After 6 months their content increased by an average of 52 % of the original content in the used raw materials. Tissue content immediately after freezing peppers and pumpkins also increased on average by 61 %, but after 3 months of storage began to decline and these changes lasted until the end of life. Freezing had an impact on the amount of hemicellulose in frozen vegetables. After 6 months of storage biofortified vegetables contained an average of 58.1 % of hemicellulose in comparison with its original content. During the freezing and storage of test and control samples of peppers and pumpkins, there is a general pattern of change in the content of sugars and polysaccharides, but after 6 months of storage the most valuable are biofortified vegetables. This is due to the high nutritional value of fresh biofortified vegetables that were used for processing.
