Abstract:
Cellulosic biofuels have been proposed to replace part of traditional liquid transportation fuels. Cellulosic biomass is the feedstock in cellulosic biofuel manufacturing. Costs associated with collection and transportation of cellulosic biomass account for more than 80 percent of the feedstock cost. By processing cellulosic biomass into pellets, density and handling efficiencies of cellulosic feedstock can be improved, resulting in reduction of transportation and handling costs. The pellet temperature is one of the most important parameter in Ultrasonic Vibration (UV-A) pelleting. There is very few literature on the pellet temperature of UV-A pelleting. This paper mainly studied how to on-line measure the pelleting temperature, also, the detailed temperature characteristics of the pellet was obtained. The results are valuable for selecting suitable pelleting parameters and controlling the quality of pellet in UV-A pelleting. Also, the accurate measurement of the pellet temperature is helpful to understand pelleting mechanism, charring, and durability issues.

Abstract:
Seed pelleting is an efficient way to improve the sowing quality of seeds. Diverse positive effect of pelleting is mostly noticeable for beet seeds. Increased size and spherical shape of seeds with shell allows to use precision seeding technology, as well as fertilizers and protective agents being part of the shell, increase their sowing potential and finally increase yields. To obtain pelleted seeds, it is required to use a specialized line with a seed pelleting machine being the main equipment. An improved design of centrifugal batch-operated seed pelleting machine has been developed and manufactured in Belarusian State Agricultural Academy. To activate the process of rolling the shell in the mixing chamber of the pelleting machine, it was proposed to use separately installed blades. Based on theoretical and experimental studies, the main structural and technological parameters of the pelleting machine has been determined to ensure the highest quality of pelleted seeds. Seeds of sugar beet of the domestic variety “Polybel” obtained in a favorable climate were selected for experimental studies. Finished mixture based on bentonite clay was selected as a filler of the seed coat. After the coat formation, the insect-fungicidal dressing agent Prestige was applied to the seeds. The seeds of sugar beet of the domestic variety “Polybel” obtained on experimental pelleting machine showed high results in germination and yield. They are comparable to imported sugar beet hybrids. Pelleting of seeds of domestic varieties of sugar beet on the territory of the Republic of Belarus can become a good alternative to imported pelleted seeds, especially considering their cost, which significantly exceeds the cost of untreated seeds.

Abstract:
An important step in improving the efficiency of crop production is the development of scientifically valid technologies and technical means of pre­sowing preparation and treatment of seeds. Among the various methods that have a positive impact on crop growth, early maturity and resistance to adverse conditions, one of the most promising is seed pelleting. (Research purpose) The reasonability of the use of pelleted seeds (dragees) was shown the shell composition of which includes the substances necessary for active growth and increase resistance to adverse effects, and, in addition, it provides a more accurate seeding. We substantiate the need for improvements to existing technologies and agricultural equipment (for example, seed pelleting machine). due to the significant lack of high­tech means of mechanization of seed pre­sowing preparation at domestic agricultural enterprises. (Materials and methods) Experimental studies have been carried out with the use of computer mathematical modeling. Results of experiments were processed by methods of mathematical statistics, statistical analysis and data processing package, research application package, filtering, analysis and modeling of technological processes. Physical and mechanical properties and quality indicators of seeds and fillers have been determined in accordance with the applicable state standards. (Results and discussion) Use has been made of a program that includes obtaining information about the processes to solve the problems of experimental studies carried out by machines for pre­-sowing treatment of seeds in accordance with the developed models of their functioning; the choice of the most effective means of measuring, recording and processing information about the operation of machines and equipment in normal operating conditions; as well as checking the effectiveness of the developed methods and tools to ensure the quality of the process in case of accidental disturbances. (Conclusions) The authors have studied main parameters and operating modes of a seed pelleting installation. An average values of the process parameters of the pre­sowing treatment of seeds have been calculated under the conditions of normal functioning of machinery and equipment taking into account the validity and reliability of the obtained characteristics. The authors have developed the technological fundamentals of the artificial coating of seed surface. The study results can be used as practical recommendations for the organization of pre­sowing treatment of seeds in order to increase seed germination and crop yields.

Abstract:
Messina (Melilotus siculus) is a new annual pasture legume with better combined waterlogging and salt tolerance than other annual legumes. Messina cv. Neptune and a new salt-tolerant rhizobial symbiont (Sinorhizobium medicae SRDI-554) were made available to Australian growers in 2017. Messina is related to the annual medics (Medicago spp.) that are nodulated by the same genus of rhizobia and regarded as sensitive to soil acidity. Because some saltland soils are acidic, it is important to understand the sensitivity of messina to soil acidity in order to avoid failures during early adoption. Acidity tolerance of the messina–Sinorhizobium symbiosis was investigated in a hydroponic experiment (inoculation with SRDI-554, or the salt-intolerant strain WSM-1115 recommended for medics), and in three acidic soils (pHCa 4.3–5.5) (inoculation with SRDI-554 ± lime pelleting of seed), in the greenhouse. In the hydroponic experiment, the percentage of messina plants (with SRDI-554) that formed nodules declined at pH levels between 5.7 (43%) and 5.5 (4%). Strain SRDI-554 was slightly more sensitive to acidity than strain WSM-1115. In the acidic soils, more plants formed nodules than in the hydroponic experiment at similar pH levels; however, without lime pelleting, nodule number was inadequate at soil pHCa &lt;5.5. Addition of lime to seed was beneficial to messina nodulation. Nodule number per plant increased from 4.0 to 9.6 with the addition of lime. The messina–Sinorhizobium symbiosis was confirmed as sensitive to low pH. At pHCa 5.5, which is the level recommended as the lower limit for growing messina, nodule number was constrained in both hydroponics and soil. The risk of suboptimal nodulation would be reduced if the recommended lower soil pH limit for growing messina is increased to pHCa 5.8, in line with most annual medics. Efforts to improve the acidity tolerance of the messina symbiosis would be best focused on the rhizobial symbiont, rather than the plant.

Abstract:
Abstract. Maintaining quality pellets with a low percentage of fines is essential to achieve growth performance benefits from pelleting diets for swine and poultry. Therefore, we investigated the formation of fines during the pelleted feed manufacturing process, transportation, and feed line delivery at the farm. A second objective was to determine the chemical composition of the pellets and fines. Results indicated that pellet durability index (PDI) was increased from the pellet mill to the fat coater, but decreased between the fat coater and load-out. Correspondingly, percentage fines were similar from the pellet mill to the cooler, but then increased at the fat coater and at load-out. Dry matter, ether extract, and acid detergent fiber were greater in fines compared to pellets, whereas crude protein was decreased in fines. The percentage of fines formed during truck unloading was not influenced by unloading speed but tended to increase from the front to the rear compartment. There was no effect of feed line location (6, 35, and 76 m from the bin) on pellet PDI, percentage fines, or the nutrient profile of pellets or fines. Across locations, fines had decreased crude protein and phosphorus, but increased acid detergent fiber, crude fiber, calcium, ether extract, and starch compared to the composition of pellets. Understanding the steps in the feed manufacturing and delivery process may allow for alternative methods to reduce the formation of fines in pelleted feeds.

Abstract:
Several experiments containing 2 field, 2 pot and I rhizotron were conducted to develop a low input agricultural practice(pelleting seed) for production of soybean plant (cv. Tidar) on heavily acid soils of Sitiung, West Sumatra. The field and polexperiments were conducted in Sitiung and in the greenhouse at the Agriculture Division, Center for the Application ofIsotopes and Radiation Technology, National Nuclear Energy Agency, Jakarta, respectively, in 1990 - 1992. The rhizotronexperiment was conducted in 1994 at the Laboratory of Microbiology, Department of Agrotechnology and Food Sciences.Wageningen University. Wageningen, The Netherlands. Lime-pel/eting seeds with the equivalent of 50 kg lime ha·1 increased nodulation, growth and yield both in unlimed and limed soils. Considerable increases in nodulatio, growth and yield were obtained when a small amount of P fertiliser (J 0 kg TSP ha·l ) was incorporated in the lime-pellet. The beneficial effects of both lime-pelleting and [lime+TSPj-pelleting were more pronounced on nodulation than on growth and yield. and greater in umimed soils than in limed soils. Large effects were obtained in nodulation, growth and yield of soybean in field experi1ltl!nts by pelleting seeds with lime or with lime + TSP. However, the pel/eted soybean plants grown in unlimed soils remained small and yields were negligible. To sustain growth and production of soybean in these acid soils, adequate quantities of lime and of P fertiliser would be necessary. In the present study, a combination of broadcast lime at 2.0 t ha-I with [lime+TSPj-pelleting of inoculated seeds was found superior to the application of 7.0 t ha-I of lime with inoculated seeds only. A I toxicity and P deficiency were the main problems in these acid soils. For the low-input production of soybeans considerations shOllld be directed to the correction of these factors.

Abstract:
Abstract The short life and high cost of ring die restrict the development of pelletizing technology severely. To solve the problem, this paper focuses on the effect of die hole structure and distribution on the die strength by finite element analysis. At first, a parametric model with one random hole surrounded by six same holes is established. Through ANSYS Design Exploration, the significant design parameters affecting the deformation and stress of the die were clarified. Furthermore, the effects of the significant parameters on the total deformation and equivalent stress were obtained by response surface analysis. In addition, the empirical equations between deformation/stress and the significant parameters were developed and the interactions of any two parameters were investigated. The results show that the equations reach a high degree of significance and the coefficient of determination R2 is 0.9803, which means it can predict the total deformation and equivalent stress correctly. Moreover, the optimal combination of the parameters was achieved. When the smallest deformation and equivalent stress of ring die are obtained in the range of parameters value, the cone angle of die hole inlet is 14.67°, the effective diameter is 2.7mm, the radial vertical distance between two adjacent die holes is 10mm and the angle is 2.7°. Using the multi-objective optimization method based on the finite element to study the influence of design parameters on the ring die strength provides an effective method and idea for the design of ring die.

Abstract:
Vortex-induced vibration is an important phenomenon for offshore engineering. For applications like the piping in the deep water oil exploration projects, the mass ratios can be of order of one [1]. Hence, there is a practical need to understand the effects of low mass ratio on vortex-induced vibrations to enhance design safety. The main purpose of this study is to numerically explore the two degrees of freedom (transverse and streamwise) responses of vortex-induced vibrations of a cylinder at low Reynolds number for the limiting case of zero mass ratio and zero damping. We aim to characterize the responses. In particular, we focus on determining the maximum amplitude values. It is a continuation from the work of Etienne and Pelletier who studied such behaviors at very low Reynolds number (Re < 50) [2]. We investigate the responses in the following parameter space: Reynolds number (75 ≤ Re ≤ 175), reduced velocity (5.0 ≤ Ur ≤ 11.0) and mass ratio (m* = {0, 0.1, 1}) with a fully coupled fluid-structure interaction numerical model based on the finite element method. Our results are generally in accordance with those from previous works for the displacement trajectories, force phase diagram, and the trends in frequency response and oscillation amplitude. The maximum transverse amplitude is found to be around 0.9 in the studied parameter space. In particular, with zero mass ratio, the maximum transverse amplitude starts to occur at values of reduced velocity higher than 6.5 for Reynolds number larger than 150. This is in contrast to the results of Etienne and Pelletier [2] who found that the maximum transverse amplitude always occurs at the reduced velocity of 6.5 for Reynolds number less than 50. Furthermore, with zero mass ratio, the maximum transverse amplitude increases when the Reynolds number increases. This behavior differs from what was suggested by Williamson and Govardhan [3] for a cylinder oscillating only in the transverse direction at Reynolds numbers in the range of 85 to 200. They found that the Reynolds number has no influence on the maximum transverse amplitude. We do not notice any response branching in this parameter space. However, the results in the present work clearly consist of two distinct characteristics. This indicates that the investigated mass ratio values encompass the critical mass ratio; whose value is estimated to be around 0.1 to 0.2.

Abstract:
Organic-resin wastes (spent resins) are generated by different purification systems employed in all types of nuclear power reactors during routine and non-routine operations. The quantities of such resin wastes, and their inventories of contaminants vary depend on the operational goals of the individual power plant. Depending on the regulatory target in the particular jurisdiction where the reactor is located, the type and amounts of radionuclides, metals and other chemical contaminants in the resin waste determine the extent of treatment required for interim storage or final disposal of the waste. Resin-waste treatment comprises different operations such as pretreatment, conditioning/stabilization and containerization that produce a waste package suitable for handling, transport, storage and disposal. One aspect of the contaminants that has significant impact on waste conditioning and the overall cost of managing such wastes are the concentrations of short half-life (arbitrarily less than approximately 30 years) radionuclides, and long half-life radionuclides, in particular carbon-14, and toxic metals present in the waste. A spectrum of resin-waste conditioning methods is available. Some methods have been applied to specific situations while others are being developed for future applications to meet the need for reducing worker dose, environmental releases, and waste-storage and disposal costs. This paper describes waste treatment options for low-level radioactive resin wastes and potential options of resin wastes containing appreciable amounts of carbon-14. Indications are that drying of the resin waste containing long half-life radionuclides such as carbon-14 and compaction or pelletizing can be favourable to allow interim dry-storage of the waste and to provide sufficient flexibility in the preparation of a suitable waste form to meet applicable waste acceptance criteria for the eventual disposal of such wastes.
