Abstract:
Food grain Wastage cripples a country’s economy to a great extent. Food grain wastage is also associated with wastage of water, manpower during agricultural activities and electricity power used in food processing industries. It even causes deforestation. Adequate measures have to be taken to properly store the food grains so that they remain edible. The proposed storage management system uses the sensors to measure the levels of humidity, temperature and ammonia gas which will help us monitor quality of the food grains. The main idea is to identify the quality of the food grains using the sensors such as Temperature, Humidity and Ammonia Gas. The Quality of the food grain is measured using the factors like Humidity, Temperature and Ammonia gas sensors and sent through Wireless Communication to the server and the server makes the decision and alarms about the quality of the food grain to the maintenance people.

Abstract:
Changes in storage environments have a significant impact on grain quality. Accurate prediction of any quality changes during grain storage in different environments is very important for human health. In this paper, we selected wheat and corn, which are among the three major staple grains, as the target grains whose storage monitoring data cover more than 20 regions, and constructed a grain storage process quality change prediction model, which includes a FEDformer-based grain storage process quality change prediction model and a K-means++-based grain storage process quality change grading evaluation model. We select six factors affecting grain quality as input to achieve effective prediction of grain quality. Then, evaluation indexes were defined in this study, and a grading evaluation model of grain storage process quality was constructed using clustering model with the index prediction results and current values. The experimental results showed that the grain storage process quality change prediction model had the highest prediction accuracy and the lowest prediction error compared with other models.

Abstract:
Topicality. These researches are due to the grain storage problem, the features of maize grain storage in metal silos under the various environmental factors, as well as more efficient using the material and technical facilities, including the grain storages of new generation. Purpose. To establish the types of grain storage facilities that are most appropriate for storing the yield of different crops, to improve metal silos and maize grain storage technologies. Materials and Methods. During experiments on maize grain storage, we used the metal silo equipped with a system of sensors to measure the temperature in different places of grain heap. We studied two models of grain storages, such as a standard construction (control) and an experimental one thermal isolated with a polyurethane layer. During the storage experiment, grain quality was monitored on grain moisture content, dockage, damage and germination. Results. Different types of grain storage facilities storing main volume of grain harvest were characterized; the technical, economic and technological advantages and disadvantages of grain storage were highlighted; directions for further development are outlined. The features of maize grain storage in the metal silos under influence of external meteorological conditions for 60 day were established. Temperature fluctuations were 7.1–13 °С in grain storage with thermal insulation, 4.5–25.9 °С – without insulation. As a result of significant temperature fluctuations, the grain was moistened by 2.2 %, its acidity increased by 1 degree, germination decreased by 7 %. At the stage of preparation for storage, maize grain should be cleaned to purity of 93–97 % by removing grain impurities. An effective method for this is fractional separation of grain. Conclusions. Thermal insulation of metal silos significantly reduces the negative impact of fluctuations in ambient air temperature, stabilizes the storage mode, and ensures high quality maize grain. The stability of grain during storage increases in the case of selection from it a fraction of grain of small, unfilled, with a low 1000 grain weight.

Abstract:
The aim of this study was to determine the effect of three grain storage times and the cultivar factor on some parameters used in commodity analysis of spring wheat grains. A field experiment was conducted in Czeslawice (Poland) using the split-plot method in 3 replicates in 27 m2 plots. This paper presents the effect of storage time (3, 15, 27 months) of grain of four spring wheat cultivars (‘Korynta’, ‘Monsun’, ‘Tybalt’, ‘Zadra’) on some technological quality characteristics. After harvest, the grains were dried to the moisture content 14% and subsequently stockpiled in a warehouse. It was observed that grains can be stored for a period of even two years with no risk if all the grain storage rules are followed. Short- and long-term grain storage (3-27 months) resulted in satisfactory values of the grain quality characteristics like grain moisture, protein content, and grain hardness index. The storage of grain did not affect negatively grain contamination with mycotoxins. No significant differences were observed in the response of the cultivars studied (grain moisture content, protein content, grain hardness index) to grain storage time. Significant differences among the cultivars were observed in the grain hardness index after 3-month storage. It was also noted that the cultivars ‘Korynta’ and ‘Tybalt’ were characterized by lower susceptibility to contamination with mycotoxins than cvs. ‘Zadra’ and ‘Monsun’. The results obtained in this study are a good indicator for cereal producers who store grains for a period of even two years, thus becoming independent of changing price conditions in the cereals market and the changing demand for and supply of animal feed and bread grain across other countries.

Abstract:
Despite the recent introduction of improved grain storage methods and technologies, many smallholder maize farmers in Ghana still use traditional storage practices and structures for storing their maize grains after harvest. This practice contributes to the high post-harvest losses in maize grain at the smallholder level largely due to insect pest infestation. Hermetic bag storage is a proven technology effective in reducing grain damage and losses from insect pests. In this study, the efficacy of the Purdue Improved Crop Storage (PICS) bag was compared with a polypropylene (PP) bag stored with maize treated with Betallic Super EC chemical and PP bag stored with maize without Betallic treatment (Control) during a 6-month storage period. Data on grain moisture content (MC), number of live insects, insect damaged kernels (IDK) and maize weight loss were collected monthly for analysis. Grain viability and nutrient analysis were also conducted before and after storage. The results showed initial grain moisture content of 11.4% was not significantly affected in the PICS bags but increased by 1-2% in the PP bags. Purdue Improved Crop Storage (PICS) bags and Betallic treatment significantly reduced insect damage grains with mean weight loss of < 5% and 6.35 % respectively compared to the control (PP bag without Betallic) treatment with mean weight loss of 21 % over the 6-month storage period. Germination rate of sampled seeds after storage in the PICS bags (75 %) was not significantly different to the initial germination rate (78 %) compared to the control (PP bag without Betallic) treatment of 56 %. Overall, maize grains stored in the PICS bags showed no signs of deterioration as compared to grains in the PP bags. The PICS bags were superior to the PP bags in terms of other grain quality metrics assessed and the nutrient characterization such as protein and carbohydrate which had no significant difference (p<0.05) between the initial and the three treatments. The results showed that PICS bags can be effective in protecting maize grains during storage. Smallholder farmers are therefore encouraged to consider this technology especially for controlling insect pests of stored maize.

Abstract:
Grains are an important food that provides important nutrients. Due to the seasonality of grain crops, humanity has always looked for options for preserving grain. Proper grain storage is critical to maintaining grain quality, preventing spoilage and ensuring food security. The centuries-old experience of farmers shows that grain storage is a complex process that requires careful planning and management. Proper grain storage has several benefits. First, it helps prevent crop losses due to spoilage, pests and diseases. Secondly, it preserves the quality of the grain, ensuring its suitability for human and animal consumption. Thirdly, it allows you to regulate the supply of grain throughout the year, ensuring its availability even during periods of low harvest. As science and technology have advanced, new, efficient, and cost-effective techniques for storing grains have been put forth. Nevertheless, the issue of product quantity and quality safety during storage remains pertinent. This page gives a general overview of the different ways that grains can be stored, such as in warehouses, silos, and polyethylene sleeves. Each approach is discussed together with its benefits and drawbacks. Gaining an understanding of these procedures would enable stakeholders to design efficient storage plans and make well-informed decisions to guarantee grain supply and quality.

Abstract:
After harvest, oilseed raw materials must be stored for a longer or shorter period of time before further processing. The task of storage is the safekeeping of the stored material with a minimal loss in quality. In order to preserve wet grain until processing, it is necessary to provide proper storage conditions. For this purpose, storage in the atmosphere of inert gases as well as storage in hermetically closed storages is applied. Such method is uncommon for oil cultures in domestic practice. Experimental research, analyzed in this paper, with emphasis on the effects of storage conditions on the preservation of soybean grain quality and the prevention of possibilities of the occurrence of the self-heating and self-ignition process, confirms the advantages of application of such method of storage for soybean grain. Soybean with the moisture content of 10.99% and 16.96% is stored in steel semi-industrial silo cells with carbon-dioxide atmosphere, and in hermetically sealed cell. The changes in temperature in the silo cells, changes in moisture content and discoloration of the soybean grains, as well as the amount of oil and protein in the grain were monitored during the experiment. The quality of the oil in grain was determined through the content of free fatty acids. The results of the research showed that, during longer period of time (216 days), the quality of the soybean grain in the sample with higher moisture content (16,96%) was preserved when storage was performed in carbon dioxide atmosphere. The storage of wet grain in a hermetically closed cell, in relation to the grain kept in carbon dioxide atmosphere, did not record significant differences in the examined indicators. Since the storage under controlled conditions did not result in the development of processes that would lead to the spontaneous heating of the soybean mass, the recommendation is to introduce such storage method for oilseed raw materials into domestic practice, with the additional aim of increasing the degree of protection against fire and explosions.

Abstract:
Rice storage is essential to meet the demand of processing industries and consumers. Thus, the objective with the study was to evaluate the effects of time and temperature storage whole grain rice grain with brown pericarp, black, and red on the percentage stained, sour, and yellow, colorimetric profile, gravimetric and volumetric yields and sensory parameters. Whole rice grains with brown, black, and red pericarp were stored in 13% at temperatures of 16, 24, 32, and 40 °C for 6 months. After 6 months of storage at 40 °C, the larger increments of yellow grains is observed, which reduces the typification of the grains, reducing the L* value, and increases the values of a* and b* for grains with brown and black pericarp and reducing L*, a* and b* for the grain pericarp red. Brown grain pericarp stored at 40 °C showed increases in the gravimetric and volumetric yield and grain with red pericarp showed an increase in volumetric yield in storage at 40 °C, compared to the beginning of storage. The firmness parameters, flavor, acceptance, and purchase intent, had the best ratings in grains with brown and red pericarp, stored at 24 °C. In general, the storage of whole rice grains in the temperature range between 16 and 24 °C is what provides the smallest changes of the parameters evaluated.

Grain Elevators have towered the plains of Southwest Kansas for over the last half of a century. Many of these large white concrete structures were built during the 1950s using a slip form concrete design. While new grain storage has been built over time, many of the original slip form structures remain a large part of the farm cooperatives storage capacity. Grain production has continued to increase and put greater demand on storage facilities and handling capabilities. Thus, there is a need for cooperatives to meet the future demands of farmers by replacing or updating grain storage assets. The objective of this project is to provide a comparative analysis of grain storage options that a cooperative, primarily the Garden City Co-op, Inc. (GCC), could utilize in making a decision to update or replace grain storage assets. The project examines three different options for grain storage including concrete, steel, and bunker storage. The project will also examine extending the life of an original slip form elevator by installing a gunite bin liner. To determine which option that provides the most economic benefit to GCC and its members, Net Present Value and the Internal Rate of Return are estimated for each grain storage option. GCC historical grain handling margins and grain storage costs were derived from historical averages and bids from projects GCC has undertaken in the past five years, respectively. The model assumes receipts as a percentage of storage to accurately represent bushels handled by a facility. Grain storage is highly variable in initial cost and the operational needs will change in every circumstance. The results indicate that a large volume of grain is needed before economic profits will be realized.

Abstract:
China is the largest grain producer and consumer in the world. Since introducing its open-door policy in the 1980's, China has become an increasingly important grain importing country. However, China's wheat imports have varied considerably from year to year. One key issue affecting China's grain imports is its large on-farm grain reserves. This thesis is intended to examine factors significant for China's on-farm grain stocks and shed some additional light on its potential impacts on China's domestic grain markets and grain import activities. The key finding is that Chinese farmers' grain supply is primarily from self-production. The Chinese government decrees that farmers be not eligible to purchase grain from government food agencies that control 70 to 80 percent of the total marketed surplus of grain in China. This policy plus the underdeveloped domestic grain and credit markets leads Chinese farmers to store a considerable amount of grain for consumption. The food- and income-security concern of Chinese farmers is found to be another important factor in Chinese farmers' grain storage decisions. The highly variable weather, a still developing infrastructure, and frequent changes in government grain policies all increase the risk faced by Chinese farmers, thus increase their food- and income-security concerns. This thesis finds that the increasing number of farm family members working off-farm can help reduce the quantity of on-farm grain storage because of the potential remittance from more stable off-farm earnings to the farm home. It is also found that farmers tend to store less as income increases due to changes in absolute risk-aversions of farmers. The last important finding of thesis is that Chinese farmers' grain storage is somewhat price-elastic, in contrast with suggestions by some Chinese economists that China's on-farm grain storage is primarily for food-security concerns and therefore generally price-inelastic. It is also found that additions to farm household grain storage is directly elastic with respect to household grain output.

Abstract:
This thesis is concerned with an investigation into current on-farm grain storage practice and with ascertaining what educational interventions, if any, are appropriate for future and more detailed consideration. The Australian grain growing, handling, and marketing industry has changed in recent times. A few years ago (1989), the grain growers only essential contact with grain marketing was through the bulk handling authorities and the Australian Wheat Board. Advice was freely available from state departments of agriculture, and the only requirement to store grain on-farm was that necessary for the grower's own needs. Now (1994), there is a possible advantage that grain stored on-farm may be used for a wide range of selling options, amongst other reasons, and market requirements are much more complex and stringent. There is a substantial body of research on grain storage techniques. At the same time there is a significant gap between researched knowledge and the use of this knowledge for on-farm storage. A major purpose of this study is to identify an improved approach to extension and farmer education that may help to reduce this gap. This thesis contains a review of the general literature on extension followed by an overview of extension in the developed world to establish the international context for Australia. Then the historical context of extension is examined briefly to understand the current situation in each state. Some educational models are reviewed to identify relationships between stakeholders and the opportunities available for and constraints to development of educational strategies. Information channels are reviewed to comprehend extension interaction and grain storage technologies are reviewed to ensure comprehension of techniques. On the basis of the literature review a field study was designed to investigate current on-farm storage practice, current extension sources for storage information and preferences for future educational interventions. This was done by a survey using a stratified random sample of grain growers and cluster selection of individuals for personal interviews. This information was complemented by informal discussion with farmers at field days. The results of the study confirmed the gap between research knowledge and on-farm implementation of this knowledge. They also demonstrated that grain growers wanted more information and gave some indicators of how this might be achieved. Major findings of the research included the need for extension coalitions and the desirability for active involvement of the grain grower. Major conclusions, for on-farm storage and extension, are drawn to form a basis for development of future extension interventions. These are aimed at ensuring grain growers have available the information needed for good storage practice. This includes an essential understanding the grain growers' needs and perceptions, early, in any planning process. It also includes the necessity for coordination of extension/education activities at local, regional and national levels. The research has some major implications for an improved approach to extension and on-farm storage. These include the establishment of a farmers-as-researcher program to implement grain storage innovations and the recognition that implemented change will need long term maintenance; often more resource intensive than the original intervention.

Abstract:
Agriculture is an important industry in Virginia, with an array of crops grown and animals produced. Virginia's crop, livestock, and poultry sectors sold agricultural products worth $1.4 billion and $2.4 billion, respectively, in 2012. One of the products, grain, serves as an important input for raising livestock and poultry. Virginia needs to import grain from other states (Eastern Corn Belt states) to meet current livestock feed requirements, an expense that raises the cost of production over locally sourced grains . Further, such movements of grain from producing-areas to demand-areas rely on the efficient and timely interaction of grain storage and transportation. Describing the details of the grain supply chain provides insights into the interplay and relationships among production, storage, transportation, and end users of grains and oilseeds in Virginia. Results of a state-wide survey of Virginia grain producers shed light on the following topics: current cropping practices; current grain storage practices; available farm-level storage and its use, age, and expected life; and future storage plans and constraints. Overall findings include, grain production in Virginia has generally increased over the last decade, yet storage capacity remains constant and continues to age; livestock and poultry populations are declining leading to less demand for feed grains and oilseeds; grain farmers report satisfaction with their current storage situation and higher returns to stored grain may encourage "non-storers" to build storage; and the majority the grain leaving the farm is hauled by truck over short distances (25 miles or less). Overall, the results provide a foundation for understanding the grain supply chain in Virginia and offer useful information to Virginia's agricultural stakeholders.

Fumigation of stored grain is a common way to kill stored-grain insect pests. However, fumigating in unsealed structures is the leading cause of control failures and subsequent development of insect resistance. Sealing the storage structure is the only practical way to ensure a complete kill of all insects at all life stages. The cost, effort, and feasibility of sealing a U.S. corrugated steel silo during construction was evaluated and compared against an Australian sealed silo designed for fumigation. Gas monitoring and thermosiphon recirculation equipment was installed on both silos. Fumigation efficacy was evaluated using pressure half-life decay times, fumigant concentrations, insect bioassays, and grain quality data. Three fumigations with phosphine (PH₃) pellets or tablets and two with VAPORPH₃OS® cylinderized PH₃ and ProFume® cylinderized sulfuryl fluoride (SF) were performed in each silo for a total of ten experimental treatments. The Australian silo required 266 man-hours to construct and cost $180 for additional sealing, compared to 359 man-hours and $3,284 for constructing and sealing the U.S. silo. The Australian silo had a maximum pressure half-life decay time of 163 s versus 50 s for the U.S. silo. At application rates of 1.5 g/mᶟ of PH₃ both silos maintained an average concentration of approximately 0.28 g/mᶟ for 14 days. With thermosiphon recirculation the average minimum-to-maximum PH₃ concentration ratio in the U.S. silo was 0.52, compared to a ratio of 0.17 when fumigating without thermosiphon recirculation. Greater than 99% adult mortality was observed in all insect bioassays which included PH₃ resistant strains of R. dominica and T. castaneum. The average emergence from fumigated bioassays was 7 adult insects, compared to an average of 383 adults for the non-fumigated controls. Grain stored for 10 months in the sealed silos increased from approximately 11.5% to 17% m.c. in the top 0.3 m of grain, and decreased in test weight from approximately 77 to 65 kg/hL. Although the Australian silo retained higher fumigant concentrations than the U.S. silo, fumigations were successful in both. Long-term storage in sealed silos is a concern because grain quality can deteriorate due to condensation and mold in the top grain layer.

Abstract:
The main objective of this study was to estimate the costs associated with different storage levels of maize for the National Cereals and Produce Board (the NCPB), the grain marketing agency of the Kenyan government.
Four storage level scenarios were considered. The first involved a zero-supply security scenario, where the model was required to simply satisfy the demand in each period. The second, third and fourth respectively, involved two, three and four months supply security scenarios, where the model was required to purchase grain equivalent to the demand for those periods. Scenario two, providing two months supply security was not discussed because it posted results similar to scenario one. The hypothesis that a stocks management model can be developed to be used by the NCPB in order to determine the optimal quantities of maize that it handles every year, while minimizing costs, was partly supported under scenarios one and three. However, despite the reduction in costs under scenario one, the lack of inventory and foreign trade was seen to increase the risks and uncertainties associated with variations in production, especially under cases of short supply. Similarly, the lack of foreign trade under scenario three was postulated to increase risks and uncertainties in periods of low production. Under scenario four, the results involved foreign trade, and inventory was positive for most years. However, these results were suboptimal and thus unreliable for policy decisions. Nevertheless, results under this scenario were very similar to the actual performance of NCPB for the period 1980 to 1990.
The results of this study show that external trade may not be the solution to a strategy of cost minimization. It was concluded, therefore, that the present strategy of self-sufficiency may be the better alternative. (Abstract shortened by UMI.)

On-farm grain storage plays a key role in the production and distribution of corn in the United States. It can have economic impacts on a farm’s profitability and production efficiency over time. With the free market system of the United States, market fundamentals are a key component of decisions made on the farm regarding construction of grain storage facilities and how they are used in marketing decisions throughout a given production and marketing year. This analysis researches how grain storage decisions in the Northern Mississippi area are effected by corn basis differentials between the Memphis, TN river market and the Northern Alabama corn market. Corn basis differentials are considered along with annual changes in corn futures market carry in response to variations in grain market fundamentals. The profitability of constructing, maintaining, and operating on-farm grain storage is analyzed based on the local history of the local corn market basis patterns and the carry priced into the corn futures market. Through this analysis it was found that the biggest obstacle affecting the profitability of on-farm grain storage was the upfront cost of the facility. As costs of the facility were incurred, grain had to be stored for longer periods of time in order to be profitable based on history of improved basis and market carry over time. On-farm storage became profitable over a shorter storage period once the upfront costs of grain storage and handling facilities were paid based on the operating costs and market conditions within the analysis. On-farm storage can be a useful tool for a farm to increase profitability over time, beyond the scope of this analysis. This analysis proves that in the Northern Mississippi area over time, grain storage can be profitable based on improved cash basis and futures market carry. However, due to ever-changing market conditions, on-farm grain storage does not replace the need for the development of grain marketing plans in order to increase the likelihood of profitability.

Unidades armazenadoras de grãos podem ser definidas como sistemas projetados e estruturados para receber, limpar, secar, armazenar e expedir grãos e oleaginosas. Para alcançar essas metas apropriadamente, estruturas, máquinas de processamento e transportadores são interligados, segundo um fluxograma lógico, e tomadas decisões operacionais. Devido à dinâmica do sistema da unidade armazenadora de grãos e a influências de fatores aleatórios externos, como o processo de colheita e a demanda do mercado, não são recomendados o emprego de métodos estáticos em estudos de avaliações e análises para este tipo de sistema. Isso se deve ao fato de que os métodos estáticos podem levar os tomadores de decisões a cometer erros, como também colocá-los em situações embaraçosas ao procurar estabelecer correlações entre as variáveis envolvidas. Por essa razão, a simulação se apresenta como a técnica mais adequada, por permitir um melhor entendimento dos parâmetros selecionados para a tomada de decisão, além de propiciar a condução de experimentos, como: análise de sensibilidade, análise de cenários, otimização e simulação de Monte Carlo. Dessa forma, visando permitir engenheiros, projetistas, gerentes e demais tomadores de decisões simularem a dinâmica operacional, conduzirem experimentações e realizarem análises de viabilidade, considerando-se unidades armazenadoras existentes e novas, foi desenvolvida uma ferramenta para estruturação de modelos de simulação. Essa ferramenta, denominada Grain Facility, foi desenvolvida utilizando-se o software Extend TM , versão 4.1.3C. Grain Facility é classificada como uma biblioteca do Extend TM , que contém um conjunto de blocos que propiciam: (i) introduzir dados que governam o sistema, (ii) simular as operações unitárias associadas ao ambiente das unidades armazenadoras de grãos, (iii) coletar e apresentar informações durante a simulação e (iv) gerar relatórios e gráficos. Para o desenvolvimento da biblioteca Grain Facility, dos modelos e dos estudos de verificação e validação, dados foram obtidos na Cooperativa Agropecuária Mourãoense Ltda. – COAMO, com sede em Campo Mourão, Paraná, Brasil. Os dados referem-se a: (i) consumo mensal de energia elétrica, (ii) consumo anual de lenha utilizada no processo de secagem, (iii) quantidades diárias de produtos recebidas, (iii) quantidades mensais de produtos expedidas, (iv) fluxogramas das unidades armazenadoras visitadas e (v) informações técnicas sobre equipamentos e estruturas. Com base nos resultados, pode-se concluir que Grain Facility possui significativo potencial para solução de problemas, uma vez que essa ferramenta permite a estruturação de modelos que são úteis em aplicações como: (i) análises de viabilidade, (ii) entendimento dos casos em estudo, (iii) estimativa do consumo de energia elétrica e combustível no processo de secagem e (iv) avaliação de sistemas novos e existentes, bem como das necessidades de expansão, remodelação e inovação tecnológica.
A grain storage facility may be defined as a designed and structured system for receiving, cleaning, drying, storing, and dispatching grains and legumes. To perform these tasks appropriately, structures, processing machines, and conveyors are logically linked and management decisions are made. Due to the dynamic of grain storage facilities and external random factors, such as the harvest process and market demand, evaluation and analysis using static techniques are not recommended. Static methodologies may lead decision makers to erroneous conclusions or put them in an awkward position when trying to correlate the several variables involved. For these reasons, simulation proves to be a more than adequate method to better understand the studied decision parameters; and it is ideal for conducting sensitivity analysis, scenario analysis, optimization, and Monte Carlo simulation. Thus, a simulation toolset was developed to allow engineers, designers, managers, and other decision makers to model the dynamic behavior of new and existing grain storage facility and conduct related experiments and feasibility analyses. This toolset, called “Grain Facility,” was developed by using Extend TM software, version 4.1.3C. “Grain Facility” is an Extend TM library holding a set of blocks that enable the user to: (i) input information which rules system operations, (ii) simulate unit operations related to the grain storage facility environment, (iii) collect and display information during the simulation process, and (iv) generate reports and graphics. For the development of models using the “Grain Facility” library and for the following study’s verification and validation sections, data were obtained from the Cooperativa Agropecuária Mourãoense Ltda. (COAMO), an agricultural cooperative headquartered in Campo Mourão, Paraná State, Brazil. The data refer to: (i) monthly electric energy consumption, (ii) annual consumption of firewood used in the grain drying process, (iii) daily quantity of product received, (iv) monthly quantity of product dispatched, (v) a flowchart of the grain storage facilities visited, and (vi) technical information about processing machines, conveyors, and structures. This study’s outcomes show that Grain Facility has significant problem solving potential. It allows the structuring of models that have various applications, such as (i) conducting grain storage facility feasibility analyses, (ii) estimating electric energy and fuel consumption at grain storage facilities, (iii) acting as teaching tools to make cases under study more readily understandable, and (iv) analyzing new and existing systems to make them more efficient or to provide direction for facility remodeling and technological updating.

In Optical Data Storage. Washington, D.C.: Optica Publishing Group, 1998. http://dx.doi.org/10.1364/ods.1998.pdp.5.

Full text
Abstract:
Work is in progress for improving the switching times of erasable as well as DOW type of optical memories. As it has been already established that the erasure time (a→c) is dominated by incubation time (τ), hence τ needs to be explored more in depth [1]. In the present work the mass, molecular diameter and density effects have been shown in addition to the temperature effects. The earlier calculations could only estimate the value of τ using arrange of critical radii values [2,6], whereas the present model can be used to calculate the exact values of critical radii using shape factor calculations for grain boundary, grain edge and grain comer nucleation separately. Knowing the material parameter of a system, one can calculate variation of x with temperature, mass or composition.

Full text
Abstract:
�The report provides a compilation of data generated on Project NG-18 that has been developed over a number of years. This report consists of two topics: one is a summary of the pipe properties developed for pipe materials used in Project NG-18; a pipe sample storage program that has been initiated to set aside samples of virgin pipe material so that when future problems develop on pipelines, original pipe materials will be available for the conduct of research. Pipe properties from over 400 pipe lengths is contained in the pipe database. This database focuses on pipe diameters from 8 inches to 42 inches and from Grade A through Grade X100. The properties that are included are the mechanical, chemical, fracture, grain size, pipe fracture data, metallurgical data, and environmental effects data. These data were collected on pipe lengths donated to the program from 1959 to present by PRCI-member companies and pipe mills. A second part of this program was to develop a procedure for the collection and storage of short pipe lengths from new construction. The goal was to have individual PRCI companies store the pipe but records of the stored pipe properties and location. The goal is to develop a supply of pipe to so that if problems occur in future years with pipe of a similar nature original pipe will be available for study of the changes in properties during the service years.
