    Cane processing energy consumption (per unit mass processed) varies between sugar mills. Although lower energy consumptions appear to indicate better performance, closer examination of the sugar extraction process reveals that more efficient extraction may increase sugar revenue sufficiently to offset higher investment and specific energy consumptions. The present analysis relates to proposed modifications in the milling process in Agroval, an old sugarcane factory. Cane processing energy consumption and sugar extraction efficiency for the current process that extracts 92.1% of the sugar, are compared to a hypothetical process similar to that in Japungu, a modern fuel alcohol distillery. Since the fermentation broth must be dilute, distilleries can use more soak water to increase juice extraction during crushing so bagasse humidity and sugar dilution in the cane juice are higher. Though more energy is expended to process cane the proposed process extracts 95.7% of the sugar content. An analysis of the substitution of the process in Agroval, based on measured and estimated data, suggests that if the evaporator steam consumption does not rise appreciably, the net revenue increases significantly. Further measurement and analysis could determine the expected improvement more accurately. (author)

    Full Text Available Sugar industry diversification is complex, being constrained by biophysical and socioeconomic conditions. Ongoing work has shown the sugarcane industry’s potential as biorefinery or its sustainable use by offering products as raw material. However, few studies have studied how such potential could be achieved by promoting a conventional sugar mill through integrating its indicators for developing an efficient diversified processing plant which would contribute towards fossil energy saving and competitiveness. This paper presents a conceptual framework for analysis based on existing knowledge regarding sugar industry state-of-the-art for evaluating diversification, using analytical hierarchy process (AHP as a tool for analysing complex systems, identifying alternatives to the current situation and discussing them to facilitate collective decision-making. Sugar mill AHP scores enabled discussion about the variables most affecting sugar mill diversification (0.332 factory yield, 0.327 sugar mill products and 0.121 sugarcane quality. The results serve as a useful guidance for formulating strategies for the optimum use of by-products in a sugar mill while maximising benefits to modify/convert a traditional sugar mill to a so-called bio-refinery.

    Full Text Available Despite Indonesia?s overall achievements during the past two decades%2C the economy is encountering a series of problems. One of the biggest challenges is the unsatisfactory performance of the state-owned enterprises (SOEs. Subsidisies and uncovered loans to the SOEs have drained the government?s fiscal resources%2C and the signing off of employees creates many social problems. Compared with the SOEs in other sectors%2C state-owned sugar mills face more serious crises which not only jeopardise the social fabric%2C but also endanger the production. Research results strengthen the statement that the basic problem in sugar mills is management inefficiency resulting in high transaction costs. This research compares the transaction costs between state-owned (Ngadiredjo and privately-owned (Kebon Agung sugar mills. The study shows that in Kebon Agung Sugar Mill transaction costs are higher than production costs%2C while in Ngadiredjo Sugar Mill the reverse is true. However%2C the high transaction costs in Kebon Agung Sugar Mill cannot be attributed directly to inefficient institutions%2C because Ngadiredjo Sugar Mill incurred high costs for plants%2C land preparation%2C and fertilizer%2C which decreased the proportion of transaction costs. If analyzed in detail%2C the following facts are revealed: (i market transaction costs in Kebon Agung Sugar Mill are higher than in Ngadiredjo Sugar Mill. This is because Kebon Agung Sugar Mill has established cooperation with sugarcane farmers in the form of extensions and transport subsidies; and (ii the political transaction costs proportion in Ngadiredjo Sugar Mill is higher than in Kebon Agung Sugar Mill because of the imposition of many ?illegal? fees.

By changing various parameters the performance of roller mill is studied using FEA software and the same is compared with above theoretical results. Based on results the optimum design is proposed.ANSYS software is used to calculate stress-strain state of roller mill.

  19. Pyrolysis and thermal oxidation kinetics of sugar mill press mud

    International Nuclear Information System (INIS)

    Press mud, a solid waste obtained from the sugar mills, has the potential of energy generation through pyrolysis and gasification. The paper reports its proximate and ultimate analyses, deformation and fusion ash temperatures, lower and higher heating values, physico-chemical and thermal degradation in nitrogen and air atmospheres. The thermal degradation was conducted in a thermogravimetric analyzer from room temperature to 900 deg C at heating rates of 20 and 40 K min-1. The thermogravimetric, derivative thermogravimetric and differential thermal analyses were carried out to determine the rate of volatiles evolution, the effect of heating rates on the thermal degradation characteristics and to determine the global mass loss kinetics of thermal degradation. The thermal degradation was found to occur in several distinct phases: each phase giving volatile evolution in an independent parallel lump. Each decomposition phase was modeled by a single irreversible reaction with respect to the solid mass. Global mass loss kinetics was also determined for the entire decomposition process, as if occurring in one single step. The integral and differential techniques were used for the determination of kinetic parameters. Using the method of Agrawal and Sivasubramanian [R.K. Agrawal, M.S. Sivasubramanian, AIChE J. 33 (1987) 7] for the total degradation zone, the orders of reaction were found in the range of 1.00-2.50 in both the atmospheres (i.e. nitrogen and air) and the activation energy in the range of 27.84-33.44 and 57.41-88.92 kJ mol-1 in nitrogen and air, respectively. The pre-exponential factor was found in the range of 32.1-95.1 and 5.10 x 104 to 5.46 x 109 min-1 in nitrogen and air atmospheres, respectively

    Since the early 20th century, a marked increase in obesity, diabetes, and chronic kidney disease has occurred in the American Indian population, especially the Pima Indians of the Southwest. Here, we review the current epidemic and attempt to identify remediable causes. A search was performed using PubMed and the search terms American Indian and obesity, American Indian and diabetes, American Indian and chronic kidney disease, and American Indian and sugar or fructose, Native American, Alaska Native, First Nations, Aboriginal, Amerind, and Amerindian for American Indian for articles linking American Indians with diabetes, obesity, chronic kidney disease, and sugar; additional references were identified in these publications traced to 1900 and articles were reviewed if they were directly discussing these topics. Multiple factors are involved in the increased risk for diabetes and kidney disease in the American Indian population, including poverty, overnutrition, poor health care, high intake of sugar, and genetic mechanisms. Genetic factors may be especially important in the Pima, as historical records suggest that this group was predisposed to obesity before exposure to Western culture and diet. Exposure to sugar-sweetened beverages may also be involved in the increased risk for chronic kidney disease. In these small populations in severe health crisis, we recommend further studies to investigate the role of excess added sugar, especially sugar-sweetened beverages, as a potentially remediable risk factor.

  2. Use of gamma radiation in the sugar mills crystallization process control

    International Nuclear Information System (INIS)

    The technical feasibility of applying the gamma-ray transmission method to the control of the saccharose crystallization process at sugar mills was investigated. Attenuation measurements using a Cs-137 gamma beam showed that the transmission factor depends on the solid phase concentration of saccharose solutions in a very definite manner. Furthermore, temperature and purity of the solutions showed no significant influence on this attenuation behaviour. Therefore, measurements of the transmission factor can be used to implement a continuous control of the saccharose crystallization process on a industrial scale in sugar mills.

    International Nuclear Information System (INIS)

    To meet Pakistan's projected power demand; about 143 GW of new generating capacity will need to be installed up to 2030. Many studies around the world have identified bagasse based cogeneration as an attractive low-cost option to place additional generating capacity on the grid. The focus of this study is the sugar industry which has long been co generating power for its own purposes is favored as the potential entry market for co-generation. This industry presents a strategic opportunity to develop a validate commercial business to overcome the barriers restricting development. Dewan Sugar Mill situated in district Thatta in Sindh province was selected as case study because of its higher crushing capacity. Power generation study for this sugar mill has been carried out. The study concludes that the mill can generate surplus power to export to the extent of about four times the current generation during the season using bagasse as fuel. These export can go to about five times the current generation subject to the condition, if alternative fuel is supplied. (author)

    International Nuclear Information System (INIS)

    Sugar Mills effluent and their effects on the surface and groundwater quality in the vicinity of Mirpurkhas Sugar Mills have been studied during the period from November 04 to February 05. The results obtained from the analysis of samples collected from factory and effluent channel indicates that all values of effluent parameters BOD/sub 5/, COD, TSS, and Oil and Grease are higher than the value recommended in NEQS. The values of physico-chemical parameters of groundwater samples (Ca, Mg, Na, HCO/sub 3/, Cl, SO/sub 4/) also shows variation in results with comparison to mill distance, but still found within the limit of WHO standards. During the environmental survey of adjacent villages, it was also observed that the local environment and quality of water is adversely being affected by mill effluent. This is obvious from samples of effluent and the comparison of results of samples of groundwater supplies taken from various locations. Therefore, it is strongly recommended that the material thrown as effluent must be treated before disposed off into channels and people must be informed about the adverse effects of effluent upon the groundwater quality.

  13. Culture of the microalga chlorella vulgaris on different proportions of sugar mill effluents

    International Nuclear Information System (INIS)

    Chlarella vulgaris was cultured in four different dilutions of sugar mill effluent media (SMEM). Bold's basal medium (BBM) was used as the control under laboratory conditions. Maximum cell growth and chlorophyll-a content were obtained on 10th day of the culture in 50% diluted SMEM, followed by those grown in BBM, and 75, 25 and 100% SMEM at stationary phase. The specific growth rate (mu g/day) of cells and chlorophyll-a of C. vulgaris grown in 50% SMEM varied significantly (p < 0.0 I) from those of C. vulgaris cultured in BBM, followed by other SMEM concentrations. Total biomass of C. vulgaris. cultured in 50% SMEM, was found to be significantly higher (p < 0.0 I) than that of C. vulgaris cultured in BBM, and 25, 75 and 100% SMEM concentrations. Similar trend was also observed in the case of optical density. Cell number and chlorophyll-a of C. vulgaris were highly (p < 0.01) and directly correlated with chlorophyll-a (r2 = 0.991) of C. vulgaris and optical density (r2 = 0.989) for the culture media containing C. vulgaris, respectively. Crude proteins and crude lipids of C. vulgaris. grown in 50% SMEM, were significantly (p < 0.01) higher than those of C. vulgaris cultured in other SMEM concentrations. Due to good growth performance exhibited in the 50% SMEM dilution, the sugar mill effluent may be used for efficient cultivation of C. vulgaris and possibly other micro algae. (author)

This paper presents a conceptual framework for analysis based on existing knowledge regarding sugar industry state-of-the-art for evaluating diversification, using analytical hierarchy process (AHP) as a tool for analysing complex systems, identifying alternatives to the current situation and discussing them to facilitate collective decision-making. Sugar mill AHP scores enabled discussion about the variables most affecting sugar mill diversification (0.332 factory yield, 0.327 sugar mill products and 0.121 sugarcane quality). The results serve as a useful guidance for formulating strategies for the optimum use of by-products in a sugar mill while maximising bene-fits to modify/convert a traditional sugar mill to a so-called bio-refinery.

    In 2011 the Inter-Tribal Council of Michigan, Inc. was awarded an Energy Efficiency Development and Deployment in Indian Country grant from the U.S. Department of Energy’s Tribal Energy Program. This grant aimed to study select Bay Mills Indian Community community/government buildings to determine what is required to reduce each building’s energy consumption by 30%. The Bay Mills Indian Community (BMIC) buildings with the largest expected energy use were selected for this study and included the Bay Mills Ellen Marshall Health Center building, Bay Mills Indian Community Administration Building, Bay Mills Community College main campus, Bay Mills Charter School and the Waishkey Community Center buildings. These five sites are the largest energy consuming Community buildings and comprised the study area of this project titled “Energy Efficiency Feasibility Study and Resulting Plan for the Bay Mills Indian Community”. The end objective of this study, plan and the Tribe is to reduce the energy consumption at the Community’s most energy intensive buildings that will, in turn, reduce emissions at the source of energy production, reduce energy expenditures, create long lasting energy conscious practices and positively affect the quality of the natural environment. This project’s feasibility study and resulting plan is intended to act as a guide to the Community’s first step towards planned energy management within its buildings/facilities. It aims to reduce energy consumption by 30% or greater within the subject facilities with an emphasis on energy conservation and efficiency. The energy audits and related power consumption analyses conducted for this study revealed numerous significant energy conservation and efficiency opportunities for all of the subject sites/buildings. In addition, many of the energy conservation measures require no cost and serve to help balance other measures requiring capital investment. Reoccurring deficiencies relating to heating, cooling, thermostat setting inefficiencies, powering computers, lighting, items linked to weatherization and numerous other items were encountered that can be mitigated with the energy conservation measures developed and specified during the course of this project.

    The anhydrous ethanol production is recent and limited, because the disadvantage of the renewable energies is the economic impossibility of the projects. Nevertheless, there are aspects to consider to achieve the anhydrous ethanol production, among which are: the cost of the raw material, the self-sufficiency of energy from the sugar cane bagasse without the need of oil burning, the larger size of the distilleries, incorporation of the Cogeneration with delivery of electricity to the public network in the sugar mill facilities, the introduction of the biotechnology to improve the processes of fermentation and subsidies to agriculture.

    Biogas production has been the main route used to exploit olive mill wastewater (OMW), after pretreatment and/or in combination with other effluents, but more recently the production of chemicals and biopolymers by biotechnological routes has deserved increasing attention by the scientific community. The present paper aims to explore the potential of fresh OMW as a source of volatile fatty acids (VFAs) and biogas. The time profile of VFAs production and the corresponding sugar consumption was followed by high-performance liquid chromatography, in batch anaerobic assays. The experimental results have revealed the very high potential of the OMW for the production of VFAs, mainly due to the high sugar concentration in the effluent (37.8 g/L) and its complete conversion into VFAs, in a time period of 2-3 days. The most abundant VFAs were acetic (48-50%), n-butanoic (12-27%), iso-pentanoic (12-14%) and propanoic (5-13%). The ratio of VFA containing even and odd carbon chains increased with the reduction in the initial chemical oxygen demand concentration of the samples used in the experiments. The conversion of the VFAs to biogas was inhibited at concentrations of 3.5 g/L of VFAs. PMID:26496487

    This study considered an average-sized sugar mill in South Africa that crushes 300 wet tonnes per hour of cane, as a host for integrating methanol and Fischer-Tropsch synthesis, through gasification of a combined flow of sugarcane trash and bagasse. Initially, it was shown that the conversion of biomass to syngas is preferably done by catalytic allothermal gasification instead of catalytic autothermal gasification. Thereafter, conventional and advanced synthesis routes for both Methanol and Fischer-Tropsch products were simulated with Aspen Plus® software and compared by technical and economic feasibility. Advanced FT synthesis satisfied the overall energy demands, but was not economically viable for a private investment. Advanced methanol synthesis is also not viable for private investment since the internal rate of return was 21.1%, because it could not provide the steam that the sugar mill required. The conventional synthesis routes had less viability than the corresponding advanced synthesis routes. PMID:25727762

    Full Text Available Problem statement: The Indian fig (a species of prickly pear cactus, has been known as Nopal, comprises an approximate area of 100,000 ha, in plantations used for human consumption. ?Pyramids? Indian fig area located in the northeastern State of Mexico has been an important Indian-fig area in the country, with 15810 ha, where a phytoplasma has been consistently present in symptomatic plant. Approach: An unknown symptomatology in the Indian fig (prickly pear cactus (Opuntia ficus-indica Mill was analyzed through grafting and a nested-PCR reaction and graft on healthy plants grown in a greenhouse. Results: The symptoms found, deforming, buds proliferation, thickening and heart-shaping in cladodes, with arrested plant growth and deep yellowing of cladodes, were all attributed to the presence of a phytoplasma given the amplification of a 1200 pb fragment of the 16S rRNA gene using primers R16 F2/R2 and R16F2n/R2 and 80% of phytoplasma transmission efficiency of successful grafts. Conclusion: Although the symptoms observed did not completely match those described for this organism in the region, a 1200 pb fragment was amplified and PCR products restriction analysis leading us to assume that the phytoplasma corresponds to subgroup 16Srll, previously reported for other crops in others world regions.

    In the present study, plant-scale process integration was applied to an Indian paper mill using the water cascade analysis (WCA) technique. Three limiting constraints, chemical oxygen demand (COD), total dissolved solids (TDS), and adsorbable organic halides (AOX), were considered for the study. A nearest neighbor algorithm was used to distribute the freshwater and recycled water among the plant operations. It was found that the limiting critical constraint depends upon the types of processes and streams involved in the integration. The limiting critical constraint can differ for different sections of the same industry, and can differ in different schemes of integration. After process integration, a 55.6% reduction in effluent flow, a 36% reduction in COD, and a 73% reduction in AOX were observed. After process integration, a 35.21% reduction in pollution costs can be achieved and, assuming the average production of the mill to be 225 tons per day, a savings of Indian rupees (INR) 1.73 per kg of paper produced can be achieved by employing process integration. The water cess was calculated as INR 3024.77 per day without integration for the sections that were considered for integration, while after integration, a 41.53% savings in the form of water cess was calculated.

Soil samples were collected after 15, 30, 45 and 90 d to determine the effect of amendments on AB-DTPA extractable metals. The results showed that AB-DTPA extractable Cd, Or, Cu, Ni and Cd increased significantly with lime and the maximum values were noted after 90 days incubation whereas the Fe, Mn and Zn content in soil increased with time but the increase was not significant. It was further noted that the increase over time in metal was not pronounced when supplied with amendments indicating their ability to chemically stabilize it compared to unamended soils. Higher values of all the heavy metals were noted in unamended soil. By comparing the different amendments, it was observed that FYM was effective in reducing the extractability/phytoavailability of all the metals under study except Pb whereby DAP was most effective as a stabilizing agent in the soil. It was concluded that in calcareous soil, FYM and DAP can be used to reduce the risk of phytotoxicity of heavy metals in contaminated soil or using wastewater for irrigation.

    This paper describes an optimization of planetary mill pretreatment and saccharification processes for improving biosugar production. Pitch pine (Pinus rigida) wood sawdust waste was used as biomass feedstock and the process parameters optimized in this study were the buffering media, the milling time, the enzyme quantity, and the incubation time. Glucose yields were improved when acetate buffer was used rather than citrate buffer. Initially, with each process variable tests, the optimal values were 100 minutes of milling, an enzyme concentration of 16?FPU/g-biomass, and a 12-hour enzymatic hydrolysis. Typically, interactions between these experimental conditions and their effects on glucose production were next investigated using RSM. Glucose yields from the Pinus rigida waste exceeded 80% with several of the conditions tested, demonstrating that milling can be used to obtain high levels of glucose bioconversion from woody biomass for biorefinery purposes.

  17. The electricity cogeneration in sugar mills and alcohol and the reduction of emissions of greenhouse gases

    International Nuclear Information System (INIS)

    Electric power in Cuba currently produces -in high proportion- plants employing fossil fuel. The price of fossil fuels and the negative influence on the environment by emissions of greenhouse gases, has indicated the need to develop other energy sources. Biomass sugarcane provides ample opportunities to produce this energy with positive economic and environmental results. The technological process for the production of sugar requires the use of mechanical energy, low power consumption compared to thermal energy requirements and their use at low pressures determine the possibility of implementing a cogeneration system of mechanical, thermal and electrical energy. The power consumption for the driving equipment of a factory is about 15-30 kw-kr / ton rod. The amount of electrical energy generated in a sugar cane factory is sufficient to meet their own needs, being able to obtain an additional amount for supply to the public network and meet the needs of other productions as is alcohol. Agricultural crop residues (RAC) and sugarcane bagasse and a liquid fuel: alcohol and gaseous fuel: different energy possibilities derived from the sugar industry reflected in the disposal of solid fuels such as is the biogas. The preparation of solid, liquid and gaseous fuels from sugar and alcohol production avoids the use of fossil fuels such as gasoline and fuel oil and gas enables not be sent into the atmosphere that impact on the greenhouse effect.

Slurry was prepared from PM having 10% of total solids and the same was hydrolyzed under acidic thermal conditions. Both press mud slurry (PMS) and pre-treated press mud slurry (PTPMS) was used as feedstock with mixed microbial consortia (MMC) and enriched mixed microbial consortia (EMMC). Mix of bioethanol and VFA were obtained in all the four cases (PMS-MMC, PMS-EMMC, PTPMS-EMC and PTPMS-EMMC), but, bioethanol and VFA yield of 0.04 g/g and 0.27 g/g, respectively obtained from PTPMS with EMMC was found to be comparatively higher. Control experiments carried out with glucose yielded bioethanol and VFA of 0.042 g/g and 0.28 g/g, respectively demonstrating that the organism was using reducible sugars in the feedstock for the generation of bioethanol by simultaneously producing the VFA from COD.

    Full Text Available Environmental Education (EE in Brazil has recently undergone an accelerated growth driven by the advancement of environmental awareness. Formal education has incorporated this theme in order to train citizens actively concerned with environmental issues in a conscious and sustainable way. A school influences the community where it operates and EE is one of the routes to try overcoming environmental problems. The schools under study are located in an Atlantic forest area, and part of these remnants is within properties of cane sugar mills. Therefore, this paper aims to analyze the inclusion of EE in schools linked to Usina Trapiche, investigating, through questionnaires, the perception of teachers on the theme at workplaces and their difficulties for addressing contents. The questionnaires were answered by 22 teachers serving about 1,300 students at the schools under study. All these schools perform EE activities, with a predominance of the solid waste issue. The difficulties reported were common to Education in general. One observed that EE is included within the studied context, but the challenge seems to be definitely including it in the syllabus and the school’s everyday life. In addition to the research, playful activities, workshops, and lectures were conducted, experiencing along with the school community the most relevant EE themes in the region.

  4. Survey of Indian issues in the state of New Mexico relating to uranium mining and milling

    International Nuclear Information System (INIS)

    Estimates of Indian uranium resources range from 11 to 50% of the US total resources. About 17% of New Mexico's reserves are known to be on Indian lands. New Mexico has produced almost half of the nation's uranium supply; over half of the known reserves are located within the state. However, the state has virtually no jurisdiction over development of Indian uranium. As a result, economic and environmental impacts on the state are beyond its control. The lack of state and federal control over these impacts is influencing how the Indians allow development to proceed. The impacts of Indian uranium development also influence state control of non-Indian. To the extent that these controls affect the availability of uranium concentrate, DOE needs to understand the issues involved. This issue paper identifies some of the related problems for both the Indians and the state and explores the reasons behind them

  8. Uranium exploration, mining and milling proposal, Navajo Indian Reservation, New Mexico

    International Nuclear Information System (INIS)

    The Secretary of the Interior has been requested to approve an exploration permit and mining lease which are part of a uranium exploration, mining, and milling Agreement, negotiated between the Navajo Tribe and the Exxon Corporation. The exploration area is a 400,000 acre tract located on the Navajo Reservation in San Juan County, New Mexico. If uranium ore in sufficient quantities to warrant development is discovered, Exxon is authorized to take a total of 51,200 acres to lease for mining, of which only 5,120 surface acres may be used for mining and milling purposes. While all exploration and predevelopment costs prior to mining must be borne by Exxon, the Navajo Tribe has reserved the right to participate in the venture on either a royalty basis or as a partner holding up to a 40 percent working interest. Impacts resulting from exploration will include disturbance of soils and vegetation and air quality degradation resulting from the vehicular movement and the operation of drilling equipment. If mining and milling takes place significant environmental impacts include: sub-surface water depletion, soils and vegetation disturbance, air quality degradation, interruption of the wildlife habitat, population increases, increased demands on community services and facilities, and disruption of established lifestyles and social patterns. Low levels of radioactive emissions will be found at mine and mill sites. Income and employment opportunities from the project to the Navajo Tribe, Navajo people, and the entire San Juan County community will be significant

  11. Electricity generation from rice husk in Indian rice mills: potential and financial viability

    International Nuclear Information System (INIS)

    Rice husk generated as a by-product of rice processing is an important energy resource. The availability of this resource in India has been assessed and the technologies for exploitation of its energy potential in the rice processing industry discussed. Nomographs have been developed for estimation of the husk required to meet the energy of parboiling, drying and milling operations. The unit cost of electricity using rice husk gasifier-based power generation systems has been calculated and its financial feasibility assessed in comparison with utility-supplied and diesel-generated electricity. With the cost and efficiency data assumed here, the unit cost of electricity produced by rice husk gasifier-dual fuel engine-generator system varies between Rs 2/kWh and Rs 7/kWh. (35 Rs approximates to SUS 1.). (author)

  13. Hydrogen photo-evolution by Rhodopseudomonas palustris 6A using pre-treated olive mill wastewater and a synthetic medium containing sugars

    International Nuclear Information System (INIS)

    Highlights: • Adsorbent matrices to convert fresh olive mill wastewater (OMWF) in feedstock. • Dry-Azolla and granular active carbon for adsorbing polyphenols from OMWF. • Photofermentative processes for biohydrogen production. • Culture mixing by means of an impeller or a magnetic stir bar. • A 30% of dephenolised OMW containing medium suits the photofermentative process. - Abstract: Increasing costs of petroleum, associated with the escalating problems of global climate change, require always greater efforts in order to produce an energy carrier as bioH2. In this study, bioH2 production using photofermentative process was investigated. Two culture broths were used: (a) a synthetic medium rich in sugars (glucose and fructose) and (b) a pre-treated fresh olive-mill wastewater (OMWF) diluted with water (30%, v:v). The pre-treatment was carried out using two different vegetable matrices (dry-Azolla and granular active carbon) to decrease both the content of polyphenols and the dark colour of wastewater. Rhodopseudomonas palustris 6A isolated from soil spread with OMW was utilized for batch growth experiments, carried out indoors under continuous light (200 μE/m2/s). When synthetic medium was used, the culture mixing was performed using either (i) a magnetic stir bar, and (ii) an impeller equipped with five turbines. The latter system made it possible to increase the bioH2 photo-evolution by 1.4 times. The specific hydrogen photo-evolution rate was 13.5 mL/g(dw)/h in the broth containing diluted OMWF and 11.8 mL/g(dw)/h in the synthetic medium containing sugars (glucose and fructose)

    Sugar profiles of different almond and chestnut cultivars were obtained by high-performance liquid chromatography (HPLC), by means of a refractive index (RI) detector. A solid-liquid extraction procedure was used in defatted and dried samples. The chromatographic separation was achieved using a Eurospher 100-5 NH(2) column using an isocratic elution with acetonitrile/water (70:30, v/v) at a flow rate of 1.0 ml/min. All the compounds were separated in 16 min. The method was optimized and proved to be reproducible and accurate. Generally, more than 95% of sugars were identified for both matrixes. Sugars profiles were quite homogeneous for almond cultivars; sucrose was the main sugar (11.46 +/- 0.14 in Marcona to 22.23 +/- 0.59 in Ferragnes g/100 g of dried weight), followed by raffinose (0.71 +/- 0.05 in Ferraduel to 2.11 +/- 0.29 in Duro Italiano), glucose (0.42 +/- 0.12 in Pegarinhos two seeded to 1.47 +/- 0.19 in Ferragnes) and fructose (0.11 +/- 0.02 in Pegarinhos two seeded to 0.59 +/- 0.05 in Gloriette). Commercial cultivars proved to have higher sucrose contents, except in the case of Marcona. Nevertheless, chestnut cultivars revealed a high heterogeneity. Sucrose was the main sugar in Aveleira (22.05 +/- 1.48), Judia (23.30 +/- 0.83) and Longal (9.56 +/- 0.91), while glucose was slightly prevalent in Boa Ventura (6.63 +/- 0.49). The observed variance could serve for inter-cultivar discrimination. PMID:20033298

    Full Text Available La frescura de la caña de azúcar es el tiempo transcurrido desde la quema o el corte del cultivo hasta que se recibe en los ingenios y es importante reducir este tiempo para evitar la pérdida de sacarosa. Por tanto, se realizó un estudio durante la zafra 2007-2008 en tres ingenios mexicanos: en Zaca [...] tepec, Morelos; en Casimiro Castillo, Jalisco; y en Ciudad Valles, San Luis Potosí. Se recopiló la información de la fecha y hora de entrada y salida de camiones, parcela de origen, identificación del camión, etc., lo cual se complementó con entrevistas a transportistas y conteos de camiones. Se elaboró un modelo matemático para analizar la influencia de varios factores que afectan la frescura. Se estableció que: 1) el tiempo de quema-corte-alzado de la caña es el componente más importante del tiempo de frescura (de 14.7 a 22.23 h, o 67 a 84 %); 2) el segundo componente más importante fue el tiempo de espera en batey (de 2.94 a 10.02 h, o 12 a 30 %); 3) el traslado tuvo la menor influencia (de 0.76 a 1.25 h, o 2.3 a 5.84 %); 4) en las parcelas con corte mecanizado y sin quema de la caña, el tiempo de frescura es aproximadamente la mitad que en las parcelas con corte manual; 5) el parque vehicular es excesivo, lo que se refleja en un muy reducido número de viajes que realiza cada unidad (0.8 a 1.63 viajes d-1), lo cual se traduce en un raquítico ingreso para los transportistas. Abstract in english Sugarcane cut-to-crush delay is the time lapse between cutting and reception in the sugar mills. It is important to reduce this time to avoid loss of sucrose. Therefore, this study was conducted during the 2007-2008 harvest in three Mexican sugar mills: Zacatepec, Morelos; Casimiro Castillo, Jalisco [...] ; and Ciudad Valles, San Luis Potosí. Information on the date and hour of truck entry and exit, origin of the sugar cane, truck identity, etc., was collected; this was complemented with interviews to truckers and truck counting. A mathematical model was developed to analyze the influence of several factors that affect cut-to-crush delay. It was established that: 1) the time between burning, cutting and pickup was the most important time component in cut-to-crush delay (14.7 to 22.23 h, or 67 to 84 %); 2) the second most important component was the waiting time at the mill (2.94 to 10.02 h, or 12 to 30 %); 3) transport to the mill had the least influence (0.76 to 1.25 h, or 2.3 to 5.84 %); 4) in the fields where cutting is mechanized and the cane leaves were not burned off, delay time was approximately half that in the fields where cutting was done manually; 5) the number of vehicles is excessive, that is, the number of trips made by each truck is very small (0.8 to 1.63 trips d-1), which translates into paltry incomes for the truckers.

    This study investigated the changes in sugars, organic acids, ?-tocopherol, ?-carotene, phenolic profiles, total phenolic content (TPC), and antioxidant capacity of jujube fruits after four drying treatments (sun-, oven-, microwave- and freeze-drying). Sugar, organic acid, phenolic compounds, ?-tocopherol, and ?-carotene were qualitatived and quantitatived by high-performance liquid chromatography. The TPC and antioxidant activity of jujube samples were evaluated using the Folin-Ciocalteau method and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging activity, respectively. Freeze-drying resulted in jujubes with higher antioxidant activity and was also a good choice for the preparation of ?-carotene from jujubes for the food industry. Microwave-dried jujubes had a higher content of protocatechuic acid, catechin, and epicatechin and maintained the same antioxidant capacity with the freeze-dried jujubes. The combination of microwave- and freeze-drying may be an efficient alternative with shorter processing time and, consequently, less impact on the nutritional value of the jujube. PMID:22958080

    2001-10-01

    The project comprised several, mutually dependent, sub-projects; mapping, investigation of ways to reduce water consumption, membrane tests aiming to find ways to recover sugar, and pinch analysis to evaluate the possibilities for improved process integration. This final report deals with the overall project results. Identified savings opportunities and savings potentials are presented. The presented measures represent an overall optimisation based on the results of all the project parts. Already during the project, measures have been implemented that are calculated to save 65 000 m{sup 3} water annually, corresponding to 10 % of the total water consumption. This saving is in level with the goals for the project. In the table below, these and additional measures are presented with a total savings potential at approximately 200 000 m{sup 3} /year water. The project will then achieve a saving of just below 35 % of present water consumption. Also in the membrane study the results surpassed the expectations. It was found that with nano filtering a sugar concentration of more than 10 %(W) could be reached in the retentate at a flux 50al/m{sup 2}h. The total sugar losses were less than 5 %, i.e. 95 % should be possible to recover. In total, a savings potential of more than 300 tonnes sugar per year is indicated. The Energy savings in the project are calculated to 7,4 GWh/year, of which 0,2 GWh/year by reduced water consumption, 0,6 GWh/year by water recovery, 1,4 GWh/year by membrane technology and 5,2aGWh/year as a result of process integration. This should be compared to the target 2,5 GWh/year. Hence, the results are almost three times the expected. The savings in monetary terms are estimated at just under SEK 5 million per year. The investment is roughly estimated at between SEK 5 and 6 million, of which SEK 4 million for the membrane equipment and SEK 0,5 million for a process water buffer tank. The remaining investment costs cover heat exchangers, control equipment and piping. This means that the total package will have a payback time of approximately one year. The environmental benefits of this project are mainly a result of the reduced energy consumption. This leads to a 1 600 tonne reduction of carbon dioxide emissions annually from reduced natural gas firing. Furthermore, the results indicate possibilities for a profitable reduction of oxygen depleting substances by over 300 tonnes sugar annually. In addition, the reduction of water consumption by 200 000 cubic meters per year results in reduced electricity and chemicals consumption in both water and sewage treatment plants.

    Full Text Available Macroinvertebrates identification and enumeration may be used as a simple and affordable alternative to chemical analysis in water pollution monitoring. However, the ecological responses of various taxa to pollution are poorly known in resources-limited tropical countries. While freshwater macroinvertebrates have been used in the assessment of water quality in Europe and the Americas, investigations in Africa have mainly focused on snail hosts of human parasites. There is a need for sampling methods that can be used to assess both snails and other macroinvertebrates. The present study was designed to evaluate the usefulness of the freshwater snail dip scoop method in the study of macroinvertebrates for the assessment of the SOSUCAM sugar mill effluents pollution. Standard snail dip scoop samples were collected upstream and downstream of the factory effluent inputs, on the Mokona and Mengoala rivers. The analysis of the macroinvertebrate communities revealed the absence of Ephemeroptera and Trichoptera, and the thriving of Syrphidae in the sections of the rivers under high effluent load. The Shannon and Weaver diversity index was lower in these areas. The dip scoop sampling protocol was found to be a useful method for macroinvertebrates collection. Hence, this method is recommended as a simple, cost-effective and efficient tool for the bio-assessment of freshwater pollution in developing countries with limited research resources.

    Full Text Available In vitro multiple shoot bud induction from leaf explants of eleven Indian cultivars of pigeon pea (Cajanus cajan L. Mill sp. under the influence of variable concentration of three different cytokinins namely BAP, KIN and TDZ on MS media has been studied. Callus of variable morphology and nature was observed for most of the cultivars except four cultivars IPA-2013, Pusa-9, T-7 and IPA-98-3 showing multiple shoot bud induction. Among cytokinins used BAP was found to be most effective. Further elongation of multiple shoot buds was achieved in the same media while rooting of regenerated multiple shoots were attempted in MS media supplemented with variable concentration of three different auxins namely NAA, IAA and IBA. Efficient rooting was achieved in the presence of NAA. Regenerated plants were successfully established in soil with acclimatization frequency varying from 25-50% with cultivar IPA-2013 showing the best response.

    American Indian (AI) children have a combined overweight and obesity prevalence of 53%. Behaviors that contribute to obesity, such as sugar sweetened beverage (SSB) intake and time spent in physical activity (PA), have been poorly explored in this population. The purpose of this study is to report body mass index (BMI), SSB intake, and time spent in PA of 7-to-13-year-old AI children who reside in rural and urban areas in Oklahoma. Cross-sectional survey study. Self-reported SSB intake in the last month, and time spent in PA were collected via questionnaires. Height and weight were professionally measured. The sample included 124 7-to-13-year-old AI children who attended a diabetes prevention summer camp in 2013. BMI percentile, overweight and obesity prevalence, SSB intake, time spent in PA, and number of participants meeting the Physical Activity Guidelines for Americans. Descriptive characteristics for BMI percentile, overweight and obesity, SSB intake, time spent in PA, and meeting PA recommendations were calculated using means, standard deviations, and frequencies. Independent t test and Chi square analyses were used to test for gender differences. Participants were 10.2 ± 1.5 years old and 57% female. Sixty-three percent were overweight or obese. Children consumed 309 ± 309 kcal/day of SSB and spent 4.4 ± 3.8 h per week in moderate-to-vigorous PA. Approximately 32% met the 2008 Physical Activity Guidelines for Americans. No gender differences were observed. The prevalence of overweight and obesity was higher than previously reported in a similar population, and higher than that of US children in the general population. SSB intake and physical activity levels were also found to be higher in this group than in the general population. PMID:25750107

    Full Text Available Cooperative Sugar industry is one of the largest industries in the country and makes significant constitution to the economy of the country. The cooperative sugar factories in Maharashtra are facing several challenges in terms of finance, management and governance. The lack of financial management in cooperative sugar mills and rising number of private sugar mills bringing the tough competition for cooperative sugar mills. In spite of the giant economic strength of this sector, it has not been given due attention. The performance of co-operative sugar mills in India and Maharashtra is very poor when compared with international sugar industry. This is due to sugar mills do not have effective control over the cost incurred during the production and low recovery of sugar from the sugarcane crushed. In order to have a better control over; the cost of new techniques to be followed. Recovery of sugar can be improved by using modern management and machineries. Hence it will improve the productivity and increase the profitability.

    Based on a case study from Venezuela, the production of raw sugar is investigated. Ideally, sugar mills operate at a constant production rate. However, safety stocks of the raw material cannot be maintained as sugar cane quality deteriorates very rapidly. Sugar cane is therefore continuously sourced in diverse quantities and qualities from hundreds of geographically dispersed haciendas and supplied to the milling process. Furthermore, due to weather conditions changing throughout the year, tight...

    Full Text Available Este estudo tem por objetivo analisar o impacto das variáveis tamanho e localização na eficiência operacional de usinas de cana-de-açúcar no Brasil na safra 2008/2009. Para tanto, realizou-se um estudo de eficiência operacional, por meio da aplicação da Análise Envoltória de Dados (AED), na qual foi [...] possível identificar as usinas mais eficientes dentre um universo de 355 e classificá-las por tamanho e localização. A análise quantitativa sugere que existe maior concentração de usinas classificadas como eficientes e de tamanho grande, localizadas no estado de São Paulo. Objetivando uma análise em profundidade, foi realizado um estudo de múltiplos casos em um grupo de usinas. Conclui-se que a eficiência operacional de usinas de cana-de-açúcar depende da variável tamanho, na medida em que as usinas de maior porte tendem a investir mais em tecnologias que proporcionam maior ganho de eficiência operacional. A eficiência também depende da variável localização, na medida em que o estado de São Paulo apresenta condições edafoclimáticas mais favoráveis à extração de uma cana-de-açúcar com maior teor de sacarose, que, consequentemente, pode influenciar na eficiência operacional de usinas de cana-de-açúcar. Abstract in english The study aims to analyze the impact of the variables size and location over the operational efficiency of sugarcane mills producing sugar and ethanol in Brazil year 2008/2009. Data concerning total milling and total production of sugar and ethanol was collected regarding Brazilian sugar cane mills. [...] An operational efficiency ranking was developed, applying Data Envelopment Analysis (DEA) technique, through which was possible to verify which were the most efficient among 355 sugarcane mills and, therefore, compare the variables size, location and operational efficiency among the Brazilian mills. The quantitative analysis suggests that among the efficient groups, there is a major concentration of larger mills, located in the state of São Paulo. Aiming an in-depth analysis, a multiple-case study was conducted in a group of sugarcane mills, and interviews with experts in the sugarcane industry were developed. Therefore, the conclusion is that operational efficiency of sugarcane mills depends on the variable location, as larger mills tend to invest more in technologies that provide major gain in operational efficiency. The operational efficiency depends also on the location of the sugarcane mill, as the state of São Paulo provides favorable edaphoclimatic conditions for the juice extraction of sugarcane with a higher level of sucrose content, hence possibly having influence over the operational efficiency.

  5. The cogeneration potential of the sugar industry in Vietnam

    International Nuclear Information System (INIS)

    Vietnam produces about 15 million tons of sugarcane per year and about five mt of bagasse. There is the potential for cogeneration using bagasse, which can also help overcome power shortages in the country. This paper analyses the potential for cogeneration from the sugar industry in Vietnam under three different scenarios and finds that between 100 and 300 megawatts of power-generating capacity could be supported by the bagasse generated from sugar mills, depending on the technology considered for sugar mills and cogeneration and the possibility of renovation of the existing mills. The paper also assesses the expense of cogeneration and finds it to be a cost-effective option for all types of sugar mill. It is found that the cost savings from cogeneration would more than offset the cost of introducing cogeneration in sugar mills with inefficient cane processing technologies. Sugar mills with modern technologies would have a significant amount of excess power and most of these plants would break-even if they sold excess power at around 4.5 cents per kilowatt hour. The break-even cost and the average production cost are sensitive to the investment cost assumptions. The paper thus suggests that cogeneration from the sugar industry is an attractive option for investors in existing mills or new sugar mills alike. (Author)

El sistema de filtros anaerobios de flujo ascendente (FAFA) como unidad principal de tratamiento biológico en la degradación de azúcares, ofrece una buena alternativa por ser considerado eficiente, de relativos bajos costos de construcción, operación y mantenimiento, con el reto central de mantener las condiciones de hábitat adecuadas para el crecimiento de la biomasa al interior del reactor. Se evaluaron cuatro medios de contacto (concha marina, material sintético, material vitrificado y grava de río), a escala de laboratorio, para encontrar el lecho de soporte de FAFA más conveniente en condiciones controladas de temperatura, régimen de flujo y acondicionamiento previo del medio bacteriano. La concha marina y el material sintético, ofrecen características de resistencia, durabilidad y facilidad de consecución y alcanzan remociones de materia orgánica mayores del 80%. Sin embargo, la concha marina alcanza las mayores remociones (89,7% para DQO y 87,8 % para DBO) gracias a su estructura física que ofrece un microambiente adecuado y por su composición química, fuente natural de alcalinidad y micronutrientes al sistema, lo que hace que se lo considere como el medio de contacto más adecuado para diseñar e implementar filtros anaerobios de lecho fijo en la industria artesanal panelera. Abstract in english The problem of treatment and final disposal of waste water coming from artisan sugar mills in the Department of Nariño, particularly those established in the Municipality of Sandoná. It lies in its economical and technological impossibility, according to its nature. The system of Up Flow Anaerobic F [...] ilter (UFAF) as the principal unit of biological treatment on the degradation of sugars, it offers a good alternative because they are considered to be efficient treatments associated with low costs of construction, operation and maintenance, with the challenge of maintaining a suitable habitat conditions for the growth of the biomass inside the reactor. The study evaluated four contact means marine shell, synthetic material, vitrified material and river gravel, through laboratory-scale testing, to find the FAFA's most suitable material under controlled conditions of temperature, flow regime and previous conditioning of the bacterial environment. The marine shell and synthetic material provide characteristics of toughness, durability and easiness of obtaining and allowing an efficient removal of organic material above 80%. However, the marine shell reaches the highest removal (89.7% for COD and 87.8% for BOD) thanks its physical structure that provides an adequate microenvironment and its chemical composition, natural source of alkalinity and micronutrients to the system, which is considered the most suitable contact mean to design and to implement the UFAF in the artisan sugar mills.

    In the recent past, the emerging India economy is highly dependent on conventional as well as renewable energy to deal with energy security. Keeping the potential of biomass and its plentiful availability, the Indian government has been encouraging various industrial sectors to generate their own energy from it. The Indian sugar industry has adopted and made impressive growth in bagasse (a renewable biomass, i.e. left after sugercane is crushed) based cogeneration power to fulfil their energy need, as well as to export a big chunk of energy to grid power. Like fossil fuel, bagasse combustion also generates various critical pollutants. This article provides the first ever estimation, current status and overview of magnitude of air pollutant emissions from rapidly growing bagasse based cogeneration technology in Indian sugar mills. The estimated emission from the world’s second largest sugar industry in India for particulate matter, NOX, SO2, CO and CO2 is estimated to be 444 ± 225 Gg yr-1, 188 ± 95 Gg yr-1, 43 ± 22 Gg yr-1, 463 ± 240 Gg yr-1 and 47.4 ± 9 Tg yr-1, respectively in 2014. The studies also analyze and identify potential hot spot regions across the country and explore the possible further potential growth for this sector. This first ever estimation not only improves the existing national emission inventory, but is also useful in chemical transport modeling studies, as well as for policy makers.

    International Nuclear Information System (INIS)

    This work was conducted in 1992 to find out the effects and causes of environmental problems due to sugar mills of Sindh. Most of the complaints were received from Nawabshah, Tando Mohammed Khan residential areas where following mills are located, emitting large amounts of fly ash from their chimneys into the atmosphere: (i) Habib Sugar Mills, Nawabshah, (II) Fauji Sugar Mills, Tando Mohammed Khan. Environmental survey of above localities was carried out which reveals that eye-allergy and asthma are the major health effects of fly ash besides the aesthetic problems. Sieve analysis of two fly ash samples viz Fauji Sugar Mills (Old Plant) and Sanghar Sugar Mills (New Plant) showed that the particle size of over 50% of fly ash was above 300 mu m. These large size black particles were unburned carbon particles, which on burning in air gave a weight loss of over 87% at 1000 centi grade. The fly ash analytical results showed that combustion of bagasse in sugar mills was not complete at all and this was not only polluting the atmosphere but also causing energy losses. (author)

    Full Text Available Sugar and sweet consumption have been popular and intrinsic to Indian culture, traditions, and religion from ancient times. In this article, we review the data showing increasing sugar consumption in India, including traditional sources (jaggery and khandsari and from sugar-sweetened beverages (SSBs. Along with decreasing physical activity, this increasing trend of per capita sugar consumption assumes significance in view of the high tendency for Indians to develop insulin resistance, abdominal adiposity, and hepatic steatosis, and the increasing “epidemic” of type 2 diabetes (T2DM and cardiovascular diseases. Importantly, there are preliminary data to show that incidence of obesity and T2DM could be decreased by increasing taxation on SSBs. Other prevention strategies, encompassing multiple stakeholders (government, industry, and consumers, should target on decreasing sugar consumption in the Indian population. In this context, dietary guidelines for Indians show that sugar consumption should be less than 10% of total daily energy intake, but it is suggested that this limit be decreased.

    Tropical countries, such as Brazil and Colombia, have the possibility of using their lands for growing biomass to produce biofuels like biodiesel and ethanol. Many studies are available which deal with the use of different sources of biomass for this purpose. From sugarcane, sucrose and other sugars (glucose and fructose) are converted into ethanol through a chain of processes. Considering the combined production of sugar and ethanol, the later is produced using part of sugarcane juice from the milling process and molasses from the sugar factory. These flows are mixed and sent to fermentation and distillation to obtain ethanol. In this work, exergy analysis is applied to the production process of sugar and anhydrous ethanol from sugar cane, using real data of one production plant located in Colombia, with capacity to process 10,000 ton a day of sugarcane. Different stages such as: growing, feedstock transport, processes plant, cogeneration plant and residues treatment are considered. Some environmental indicators based on the exergy concept are proposed for analyzing the sugar and ethanol production. According to these indicators, the Exergetic Density, Rational Exergetic Efficiency and the Renewability Performance Indicator, the ethanol production process can not be considered renewable due mainly to the irreversibilities of the energy conversion processes.

  4. Scandium as tracer in the sugar and alcohol agroindustry

    International Nuclear Information System (INIS)

    Neutron activation analysis was used to develop a method of measuring the soil content in a sugar cane consignment. When sugar cane is cut and taken to the sugar and alcohol industries, different quantities of soil are loaded with the stalks, depending on harvesting mechanization and weather conditions. Despite the washing process before crushing, significant amounts of soil have been found in cane delivered to mills. Different soils were sampled at several mills in the State of Sao Paulo, as well as sugar cane stalks of the SP70-1143 variety grown on such soils. Elements present in soil but not in sugar cane have been studied to act as tracers of unwanted impurities. Sc has proved to be an efficient tracer of the soil entering these industries with the sugar cane. (author) 12 refs.; 3 figs.; 1 tab

  5. Sugar industry dilemma in NWFP

    International Nuclear Information System (INIS)

    Sugarcane is an important cash-crop in Pakistan, ranking fourth in average cultivation after wheat, rice and cotton. It contributed 6.3 percent to the national agricultural value addition and 1.3 percent of the GDP during 2002-2003. It provides direct employment to more than 10,000 persons in NWFP. Sugarcane is grown over an area of more or less one million hectares in Pakistan, the Punjab shares 66.8%, Sindh 23.5% and NWFP shares 9.5% of the total area and 63.7, 26.5 and 9.7% of the production, respectively (Agriculture statistics of Pakistan FRS 2003). The national average cane-yield (47 tonnes per hectare) is far below the existing potential, Sindh with 53 tonnes per hectare is the leading province, followed by NWFP (48 tonnes) and Punjab (45 tonnes per hectare), respectively. In Pakistan, 73 mills are in operation. On the average, these Sugar Mills produce 3.52 million tons Sugar and employed labour force of 1.06 million persons, involving about nine million people of rural population in the production of sugarcane in 2002. In the year 2002-03, cane production was over 52 million tonnes; the Mills utilized (80.28%) of the total cane production with a yield of 3.66 million tonnes of sugar. Part 1 of this paper discusses the importance of sugarcane crop and sugarcane industry towards national economy. In part 2, problems of varied horizon have been covered, in detail, with sound viable recommendations. Finally, conclusions have been drawn in part 3 for consideration by all relevant stakeholders of the sector. To avert problems like low cane-yield, minimum return to farmers, negative attitude and delaying tactics in payments, policy makers and decision-support unit of the province should ensure the following: no further expansion of sugar-mills on political grounds and without viable feasibility; immediate improvement in water-courses, improvement of irrigation efficiency, develop cane-varieties with high sucrose-recovery percentage, reduce cost of production of inputs; provide subsidy to cane growers who should also be paid for their produce well on time by the mills. It is recommended that support-price fixation system and timely payment to farmers should be designed and implemented properly. (author)

  6. Developments in beet and cane sugar extraction

    Energy Technology Data Exchange (ETDEWEB)

    Iverson, C.; Schwartzberg, H.G.

    1984-01-01

    This paper reviews the various types of extractors used in the extraction of sugar from beet and sugar cane. The types of extractors described are as follows:- Countercurrent Screw - Conveyor Extractors, (Tower Extractors, Slope Extractors), Countercurrent Drag Chain Extractors, Multistage Cross-Flow Extractors, Trommel Extractors, Multistage Scroll Extractors, Diffustion Batteries. Reduced capital costs and power expenditures and slightly higher cane sugar yields can be obtained by combined milking and diffusion extraction as opposed to multi-stage milling. The mechanical reliability of the machinery is emphasized and special attention is given to extraction procedures. Nowadays the trend in beet and cane sugar extraction is toward the use of larger and larger units which helps minimize labor and capital costs per unit of product.

    Sugars are used by the industry to enhance the attractiveness of foods and drinks. These added sugars, or 'free sugars, are not easily identified in food or drink labels. Certain manufactured foods and drinks with 'safe' names, such as dried fruit and fruit juice, still contain free sugars and can be confusing. Guidance states that daily consumption of free sugars should be less than 10% of total energy intake (no more than 5% in the UK). However, it is found that both tooth decay and obesity are associated with consumption of free sugars in large quantities and at inappropriate times. PMID:26506805

  19. Anomeric Anhydro Sugars

    Science.gov (United States)

    McGill, Nathan W.; Williams, Spencer J.

    Anomeric anhydro sugars are sugar derivatives where the anomeric carbon participates in an acetal linkage with two of the hydroxyl groups of the sugar. They are essentially intramolecular glycosides, and their bicyclic nature provides a powerful conformational constraint that greatly influences their reactivity. This chapter reviews the occurrence, properties, formation, and reactions of anomeric anhydro sugars. Particular emphasis is placed on 1,2- and 1,6-anhydropyranoses, including conformational aspects and ring-opening reactions. Epoxide-containing 1,6-anhydro sugars (Černý epoxides) are briefly reviewed, and the formation and some reactions of the 1,6-anhydro sugar enone, levoglucosenone, is covered. An overview is given of the use of 1,2-anhydro sugar as glycosyl donors. Also discussed are the formation and reactions of anomeric anhydro sugars containing nitrogen, sulfur, or selenium.

    1998-01-01

    The consumption of sugar is relatively high in Denmark - and other industrial countries - and many persons have a consumption which exceeds the recommended level of maximally 10% of energy intake. A high sugar consumption may reduce the nutrient density of the diet and increase the risk of vitamin and mineral deficiency, especially in low energy consumers. The sugar intake and the fat intake, expressed as percentage of energy, usually show an inverse association. This has lead to the statement that a diet with both a low sugar content and a low fat content is incompatible, but we will argue that this is not the fact. The significance of sugar for the development of obesity is not clarified. A high fat content in the diet seems to promote the development of obesity, while a high carbohydrate content tends to reduce obesity. It is not known if sugar in this connection is comparable to the other carbohydrates in the diet, primarily because of the high energy density of sugar. Diabetes mellitus and heart diseasesdo not seem to have any direct connection with a high sugar consumption. Sugar continues to be a risk factor for the development of caries. Further, it cannot be excluded that high sugar consumption is a risk factor for cancer in the gastrointestinal tract or for Crohn's disease. It seems reasonable to keep the current recommendations about sugar intake.

Also the amount of sugar cane bagasse ash increase, workability of concrete increases.

  6. Sugar and Other Sweeteners

    Science.gov (United States)

    Godshall, Mary An

    Sugar and starch are among the most abundant plant products available, and large industries exist worldwide to extract and process them from agricultural sources. The world production of sugar (sucrose from cane and beet) in 2004/2005 was 142 million metric tons, raw value, 1 with 24.8 percent of that being beet sugar and 75.1 percent being cane sugar.2 The proportion of beet sugar to cane sugar has fallen steadily since about 1971, when it constituted 42.8 percent of total sugar production. The decline in total beet sugar proportion over the last ten years represents not so much a decline in beet production, which has remained in a range of 33-39 million metric tons, but rather a continued increase in cane sugar production from around 70 million metric tons in 1991 to 112 million metric tons.2 The production of total world sugar has also risen dramatically since 1971/72, when it was 71.7 million tons.3

    Directory of Open Access Journals (Sweden)

    N. M. Makandar

    2015-09-01

    Full Text Available Sugar industry is the largest agro-based industry located in the rural India. About 45 million sugarcane farmers, their dependents and a large mass of agricultural labours are involved in sugarcane cultivation, harvesting and ancillary activities, and constituting 7.5 per cent of the rural population. Beside these, about 0.5 million skilled and semi-skilled workers, mostly from the rural areas are engaged in the sugar industry. The sugar industry in India has been a focal point for socio-economic development in the rural areas by mobilizing rural resources, generating employment and higher income, transport and communication facilities. Further, many sugar factories have established schools, colleges, medical centres and hospitals for the benefit of the rural population. Some of the sugar factories have also diversified into by-product based industries and have invested and put up distilleries, organic chemical plants, paper and board factories and cogeneration plants. The industry generates its own replenish able biomass and uses it as fuel without depending on fossil fuel. The sugar industry’s contribution to the Indian economy is, therefore, enormous.

    Full Text Available American tegumentary leishmaniasis (ATL is present in all regions of Pernambuco State, Brazil, where it is spreading, with the emergence of foci in new areas like the Municipality (County of Moreno in Greater Metropolitan Recife. The objective of the current study was to assess the prevalence of infection and identify autochthonous cases of ATL. In April 2006 a population survey was performed using a questionnaire and the Montenegro skin test (MST in 481 individuals from the Pinto Sugar Mill, of whom 47% were males and 74% were younger than 30 years. One hundred forty-four individuals (30% showed a positive MST. Of these, five presented active lesions, 41 were cured after meglumine antimoniate treatment, and one showed a spontaneous cure. Indirect immunofluorescence (IIF was performed on sera from 89 individuals and showed a 36% positive rate. The high ATL prevalence demonstrates the epidemiological spread of the disease in Greater Metropolitan Recife, a worrisome development since there are no effective measures for ATL control except ecological awareness raising to minimize the risk of infection.A leishmaniose tegumentar americana incide em todas as regiões do Estado de Pernambuco, Brasil, onde se apresenta em expansão, com o surgimento de focos em novas áreas, como o Município de Moreno, na região metropolitana do Recife.

  18. Quantitation of trans-aconitic acid in different stages of the sugar-manufacturing process.

    Science.gov (United States)

    Montoya, Guillermo; Londono, July; Cortes, Paola; Izquierdo, Olga

    2014-08-20

    The sugar cane industry has seen how biomass production in sugar mills would be converted to a readily available source of molecules besides sugar. Properly managed, byproducts would be transformed into a sustainable source of renewable and environmentally friendly chemical products. As a principal and more abundant organic acid in sugar cane juice, trans-aconitic acid (TAA) has been studied for use as a plasticizer in the polymer industry. However, up to now no industrial-scale application has been reported. As a reasonable approach to recover TAA from a sugar mill, first, an analytical method to determine its presence in all stages of the sugar-manufacturing process is needed. A new modern method was developed to measure TAA in seven stages in a sugar mill located in Valle del Cauca, Colombia. The stages with higher content of TAA were syrup, with 3363.6 ± 589.3 mg/L, and honey (molasses), with 6110.05 ± 139.5 mg/L. PMID:25098840

    The processes and transformations occurring in the Antarctic aerosol during atmospheric transport were described using selected sugars as source tracers. Monosaccharides (arabinose, fructose, galactose, glucose, mannose, ribose, xylose), disaccharides (sucrose, lactose, maltose, lactulose), alcohol-sugars (erythritol, mannitol, ribitol, sorbitol, xylitol, maltitol, galactitol) and anhydrosugars (levoglucosan, mannosan and galactosan) were measured in the Antarctic aerosol collected during four different sampling campaigns. For quantification, a sensitive high-pressure anion exchange chromatography was coupled with a single quadrupole mass spectrometer. The method was validated, showing good accuracy and low method quantification limits. This study describes the first determination of sugars in the Antarctic aerosol. The total mean concentration of sugars in the aerosol collected at the "Mario Zucchelli" coastal station was 140 pg m-3; as for the aerosol collected over the Antarctic plateau during two consecutive sampling campaigns, the concentration amounted to 440 and 438 pg m-3. The study of particle-size distribution allowed us to identify the natural emission from spores or from sea-spray as the main sources of sugars in the coastal area. The enrichment of sugars in the fine fraction of the aerosol collected on the Antarctic plateau is due to the degradation of particles during long-range atmospheric transport. The composition of sugars in the coarse fraction was also investigated in the aerosol collected during the oceanographic cruise.

    This paper focuses on preserving and strengthening two resources culturally and socially important to the Shoshone-Bannock Indian Tribe on the Fort Hall Reservation in Idaho; their young people and the Pacific-Northwest Salmon. After learning that salmon were not returning in significant numbers to ancestral fishing waters at headwater spawning sites, tribal youth wanted to know why. As a result, the Indian Summer project was conceived to give Shoshone-Bannock High School students the opportunity to develop hands-on, workable solutions to improve future Indian fishing and help make the river healthy again. The project goals were to increase the number of fry introduced into the streams, teach the Shoshone-Bannock students how to use scientific methodologies, and get students, parents, community members, and Indian and non-Indian mentors excited about learning. The students chose an egg incubation experiment to help increase self-sustaining, natural production of steelhead trout, and formulated and carried out a three step plan to increase the hatch-rate of steelhead trout in Idaho waters. With the help of local companies, governmental agencies, scientists, and mentors students have been able to meet their project goals, and at the same time, have learned how to use scientific methods to solve real life problems, how to return what they have used to the water and land, and how to have fun and enjoy life while learning.

The sugar cane pulp has been previously alkalinised, dried, and milled and the particles had been classified in a range of [...] grain sizes. Experimental assays were performed, varying the proportion of the resin and the reinforcement and the size of the cane pulp fibre, keeping the pressure and moulding temperature constant. These composites were characterised according to physical and chemical properties, through test bodies produced in moulds according to ASTM standards. The experiments performed showed that the use of sugar cane pulp as reinforcement in polymeric composites represents an option for reducing costs in industrial applications, thus suggesting a significant industrial applicability of the product.

  8. Intestinal sugar transport.

    Science.gov (United States)

    Drozdowski, Laurie A; Thomson, Alan B R

    2006-03-21

    Carbohydrates are an important component of the diet. The carbohydrates that we ingest range from simple monosaccharides (glucose, fructose and galactose) to disaccharides (lactose, sucrose) to complex polysaccharides. Most carbohydrates are digested by salivary and pancreatic amylases, and are further broken down into monosaccharides by enzymes in the brush border membrane (BBM) of enterocytes. For example, lactase-phloridzin hydrolase and sucrase-isomaltase are two disaccharidases involved in the hydrolysis of nutritionally important disaccharides. Once monosaccharides are presented to the BBM, mature enterocytes expressing nutrient transporters transport the sugars into the enterocytes. This paper reviews the early studies that contributed to the development of a working model of intestinal sugar transport, and details the recent advances made in understanding the process by which sugars are absorbed in the intestine.

    2004-01-01

    The ion milling of sapphire is a complicated operation due to several characteristics of the material itself. It is a relatively hard transparent nonconductive crystalline material that does not transfer heat nearly as well as metals that have been successfully ion milled in the past. This investigation involved designing an experimental arrangement, using existing ion milling equipment, as the precursor to figuring the surface of sapphire and other insulating optical materials. The experimental arrangement employs a laser probe beam to constantly monitor the stresses being induced in the material, as it is being ion milled. The goal is to determine if the technique proposed would indeed indicate the stress being induced in the material so that these stresses can be managed to prevent failure of the optic.

  10. Optimization of hammer mills

    International Nuclear Information System (INIS)

    A simple mathematical model is proposed for the residence time distribution of crushed grain in hammer mills. The residence time distribution of the crushed grain, product quality, and the total energy consumption under various operation conditions (number of hammer rows, number of hammers in a row, mesh size of screen, velocity and output of the mill has been used as variables) was studied on a pilot hammer mill. The radiotracer was used for the experimental verification of the model and for the determination of a holdup (the magnitude of the rotating grist layer) on the pilot scale and partly also on the full-scale mills. The impulse responses were influenced by transport processes behind the screen. This effect had to be taken into account during the analysis of experimental data. The method of a non-linear regression analysis was applied for the evaluation of parameters of the mathematical model. (author)

    Oder, R.R.; Borzone, L.A.

    1990-05-01

    Results of a technical and economic evaluation of application of the Pitt Mill to fine coal grinding are presented. The Pitt Mill is a vertically oriented, batch operated, intermediate energy density (0. 025 kW/lb media), stirred ball mill. The mill grinds coal from coarse sizes (typically 3/16 inch or 4 mesh topsize) to the 10 micron to 20 micron mean particle diameter size range in a single step using a shallow grinding bed containing inexpensive, readily available, course grinding media. Size reduction is efficient because of rapid product circulation through the grinding bed caused by action of a novel circulation screw mounted on the agitator shaft. When a dispersant is employed, the grinding can be carried out to 50% to 60% solids concentration. Use of coarse grinding media offers the possibility of enhanced mineral liberation because size reduction is achieved more by impact shattering than by attrition. The batch method offers the possibility of very close control over product particle size distribution without overproduction of fines. A two- phase program was carried out. In the first phase, Grinding Studies, tests were run to determine a suitable configuration of the Pitt Mill. Machine design parameters which were studied included screw configuration, media type, agitator RPM, time, media size, and slurry chamber aspect ratio. During the last part of this phase of the program, tests were carried out to compare the results of grinding Pocahontas seam, Pittsburgh {number sign}8, and East Kentucky Mingo County coals by the Pitt Mill and by a two-stage grinding process employing a Netzsch John mill to feed a high energy density (0.05 kW/Lb media) disc mill. 22 refs., 25 tabs.

    International Nuclear Information System (INIS)

    The ''Uranium Mill Tailings Radiation Control Act of 1978,'' Public Law 95-604, directs the U.S. Department of Energy (DOE) to undertake remedial actions at designated inactive uranium mill sites and associated vicinity properties. The purpose of the remedial actions is to stabilize and control the uranium mill tailings currently stored at the sites in a safe and environmentally sound manner in order to minimize radiation health hazards to the public. These remedial actions are to be undertaken by the DOE in cooperation with the affected states and Indian tribes and performed in accordance with standards promulgated by the U.S. Environmental Protection Agency (EPA). The disposal sites, which could be the processing sites, will be acquired by the states with title passing to the DOE and will be licensed by the U.S. Nuclear Regulatory Commission (NRC). The DOE's authorization to conduct the program terminates seven (7) years following the promulgation of the EPA standards (January 1983). The current cost estimate for the project in 1982 dollars is $540 million, however, it is expected that this estimate will be somewhat reduced following completion of a review now in progress

    Villela Filho, Murillo; Araujo, Carlos; Bonfá, Alfredo; Porto, Weber

    2011-01-01

    Carbohydrates are nowadays a very competitive feedstock for the chemical industry because their availability is compatible with world-scale chemical production and their price, based on the carbon content, is comparable to that of petrochemicals. At the same time, demand is rising for biobased products. Brazilian sugar cane is a competitive feedstock source that is opening the door to a wide range of bio-based products. This essay begins with the importance of the feedstock for the chemical industry and discusses developments in sugar cane processing that lead to low cost feedstocks. Thus, sugar cane enables a new chemical industry, as it delivers a competitive raw material and a source of energy. As a result, sugar mills are being transformed into sustainable biorefineries that fully exploit the potential of sugar cane. PMID:21637329

  6. Comparison of combustion and pyrolysis for energy generation in a sugarcane mill

    International Nuclear Information System (INIS)

    Highlights: • Biomass to energy processes for sugarmills via combustion and pyrolysis are modelled. • Models compared based on technical and economic performance for two mill efficiencies. • Combustion more suited for sugar mill energy supply. • Pyrolysis based models have higher overall process efficiencies. • Pyrolysis contributes more towards environmental mitigation but is less profitable. - Abstract: The study focusses on the comparison of biomass to energy conversion process (BMECP) models to convert sugar mill biomass (bagasse) into energy products via combustion and pyrolysis as thermochemical pathways. Bagasse was converted to steam and electricity via combustion using 40 bar, 63 bar and 82 bar Condensing Extraction Steam Turbines (CEST) systems and a 30 bar back pressure steam turbine (BPST) system. Two BMECPs, namely partial fast pyrolysis and pure fast pyrolysis systems, were modeled for the pyrolysis pathway. In the Pure Fast Pyrolysis BMECP all the input bagasse stream was converted to pyrolysis products, with subsequent combustion of some of these products to generate steam and electricity for sugar mill operations. In the partial fast pyrolysis BMECP, a fraction of the bagasse is combusted directly to supply steam and electricity to the sugar mill, while the remaining fraction is pyrolyzed to generate pyrolysis products. All process models were simulated in AspenPlus® and were assessed on their ability to supply the energy requirement of to two sugar mill scenarios: More efficient mill and less efficient mill. The economic viability of BMECPs was determined using Aspen Process Economic Analyzer. Both combustion based and pyrolysis based BMECPs were capable of meeting the energy requirement of the sugar mill, although the pyrolysis based BMECP had limited steam and electricity production rates due to the accumulation of energy in pyrolysis products. High energy valued pyrolysis products resulted in higher overall process efficiencies of 85.09% and 87.65% for partial fast pyrolysis and Pure Fast Pyrolysis BMECPs respectively compared to 77.48% for the most efficient combustion BMECP (82 bar CEST). CO2 savings were higher for the pyrolysis based BMECPs due to the sequestration of carbon in pyrolysis products. The 63 bar CEST combustion system was the most economic viable option, while the Pure Fast Pyrolysis BMECP was the least viable. The increased energy efficiency and environmental benefits of pyrolysis-based processes are therefore off-set by increases in production costs

    Oil palm biomass, namely empty fruit bunch and frond fiber, were pretreated using a planetary ball mill. Particle sizes and crystallinity index values of the oil palm biomass were significantly reduced with extended ball mill processing time. The treatment efficiency was evaluated by the generation of glucose, xylose, and total sugar conversion yields from the pretreatment process compared to the amount of sugars from raw materials. Glucose and xylose contents were determined using high-performance liquid chromatography. An increasing trend in glucose and xylose yield as well as total sugar conversion yield was observed with decreasing particle size and crystallinity index. Oil palm frond fiber exhibited the best material yields using ball milling pretreatment with generated glucose, xylose, and total sugar conversion yields of 87.0, 81.6, and 85.4%, respectively. In contrast, oil palm empty fruit bunch afforded glucose and xylose of 70.0 and 82.3%, respectively. The results obtained in this study showed that ball mill-treated oil palm biomass is a suitable pretreatment method for high conversion of glucose and xylose. PMID:24908052

  14. Starches, Sugars and Obesity

    Directory of Open Access Journals (Sweden)

    2011-03-01

    Full Text Available The rising prevalence of obesity, not only in adults but also in children and adolescents, is one of the most important public health problems in developed and developing countries. As one possible way to tackle obesity, a great interest has been stimulated in understanding the relationship between different types of dietary carbohydrate and appetite regulation, body weight and body composition. The present article reviews the conclusions from recent reviews and meta-analyses on the effects of different starches and sugars on body weight management and metabolic disturbances, and provides an update of the most recent studies on this topic. From the literature reviewed in this paper, potential beneficial effects of intake of starchy foods, especially those containing slowly-digestible and resistant starches, and potential detrimental effects of high intakes of fructose become apparent. This supports the intake of whole grains, legumes and vegetables, which contain more appropriate sources of carbohydrates associated with reduced risk of cardiovascular and other chronic diseases, rather than foods rich in sugars, especially in the form of sugar-sweetened beverages.

  15. Energy saving in the sugar cane agroindustry; Ahorro de energia en la agroindustria azucarera canera

    1996-07-01

    The traditional sugar mill is inefficient from the energy point of view. Most of the sugar mills were designed to use all the available bagasse, due to the risk of spontaneous ignition and environmental pollution. Consequently, the steam generators, the turbines and other components were designed to work with low efficiencies. Each ton of sugar produced generates a power potential equivalent to four to six oil barrels (bagasse and residues). That is to say, a sugar mill is capable of producing 500 ton/day of sugar, equivalent to an oil well of 2000 to 3000 barrels/day and one thermoelectric power plant of 15,000 kW. Under this context an analysis is made of the sugar mills in Latin America and the Caribbean as one of the ways of increasing their efficiency and obtain great energy savings. As far as steam generation the appropriate use of energy is dictated by the boilers' efficiency. [Spanish] El ingenio azucarero tradicional es ineficiente desde el punto de vista energetico. La mayoria de los ingenios azucareros se disenaron para usar todo el bagazo disponible, debido al riesgo de ignicion espontanea y contaminacion. En consecuencia, los generadores de vapor, las turbinas y demas componentes fueron disenados para trabajar con bajas eficiencias. Cada tonelada de azucar producida genera una potencialidad energetica equivalente de cuatro a seis barriles de petroleo (bagazo y residuos). Es decir, un ingenio capaz de producir 500 ton/dia de azucar equivalente a un pozo de petroleo de 2000 a 3000 barriles/dia y una termoelectrica de 15000 kW. Bajo este contexto se hace un analisis del ingenio azucarero en Latinoamerica y el Caribe como una de las vias para incrementar su eficiencia y lograr grandes ahorros en la energia. En cuanto a generacion de vapor se refiere, el buen uso de la energia viene expresado por la eficiencia de las calderas.

  17. The ultrasound-assisted sugar extraction from sugar beet cossettes

    International Nuclear Information System (INIS)

    The aim of this work was to study the ultrasound-assisted water extraction of sugar from sugar beet cossettes. The ultrasound bath device (25 kHz, 200 W) was used. The sonication accelerated sugar diffusion at both temperatures 18 deg C and 77.6 deg C and gave the higher level of dry matter content SS (4-6 percent) and sugar content CK (7-22 percent) in juice. The SS and CK depended on time of exposition, time and temperature of extraction. In particular, the effects of 5 min ultrasound-assisted extraction were equal to 20 min extraction in traditional conditions. The shorter time, lower temperature, higher efficiency and purity of juice could be the effects of sugar extraction with ultrasound. The change of thickness of diffusion membrane, microflows in tissue as well as it's environment caused by ultrasound was the reason of acceleration of sugar extraction

    Milling tests were run on families of High Speed Steel (HSS) end mills to determine their lives while machining 304 Stainless Steel. The end mills tested were made from M7, M42 and T15-CPM High Speed Steels. The end mills were also evaluated with no coatings as well as with Titanium Nitride (TiN) and Titanium Carbo-Nitride (TiCN) coatings to determine which combination of HSS and coating provided the highest increase in end mill life while increasing the cost of the tool the least. We found end mill made from M42 gave us the largest increase in tool life with the least increase in cost. The results of this study will be used by Cutting Tool Engineering in determining which end mill descriptions will be dropped from our tool catalog.

  2. Incorporated residues to sugar cone during the industrial processing evaluated by neutron activation analysis

    International Nuclear Information System (INIS)

    In the Brazilian sugar and alcohol industry a modern agronomic and industrial technology has been developed during the last years, due to the high demand for sugarcane. The intensive harvest mechanization has increased the soil levels in the cane delivered to the mills despite of the introduced washing systems. Electric welding has been used to recuperate the rollers of the mill and other metallic components thus increasing the contents of metals in the processed material. Samples of cane, juice and bagasse were colected at several points of the milling tandem and submitted to neutron activation analysis. The concentrations of Fe, Cr, Co, Zn, Br and Cs showed an increment through the mill, indicating the contribution of the rollers wear. Sc and the rare earth elements La, Ce, Sm and Eu had about the same levels in all samples, therefore they must have come with the soil adhered to the cane. (author)

  7. Mill’s Liberal Feminism: Its Legacy and Current Criticism

    Directory of Open Access Journals (Sweden)

    MARIANA SZAPUOVÁ

    2006-12-01

    Full Text Available This paper highlights John Stuart Mill’s views on the problem of gender equality as expressed in The Subjection of Women, which is commonly regarded as one of the core texts of Enlightenment liberal feminism of the 19th century. In this paper, the author outlines the historical context of both Mill’s views and his personal biography, which influenced his argumentation for the emancipation of women, and considers Mill’s utilitarianism and liberalism, as the main philosophical background for his criticism of social conditions that subordinated women. She reflects on some of the philosopher’s ideas and arguments for equality and friendship between women and men which may still be considered noteworthy and relevant. Attention is also given to the main lines of contemporary reception of Mill’s liberal feminism from the perspective of current feminist philosophy, within which certain critical views predominate. Despite some problematic points in Mill’s considerations, his essay on women’s subjection may be regarded as one of the philosophically most interesting conceptions of liberal feminist thinking.

  8. Mining and milling of uranium ore: Indian scenario

    International Nuclear Information System (INIS)

    The occurrence of uranium minerals in Singhbhum Thrust belt of Eastern India has been known since 1937. In 1950, a team of geologists of the Atomic Minerals Division was assigned to closely examine this 160 km long belt. Since then, several occurrences of uranium have been found and a few of them have sufficient grade and tonnage for commercial exploitation. In 1967, the Government of India formed Uranium Corporation of India Ltd., under the administrative control of the Department of Atomic Energy, with the specific objective of mining and processing of uranium ore and produce uranium concentrates. At present the Corporation operates three underground uranium mines, one ore processing plant with expanded capacity, and two uranium recovery plants. Continuing investigations by the Atomic Mineral Division has discovered several new deposits and favourable areas. The most notable is the large Domiasiat deposit of the sandstone type found in the State of Meghalaya. This deposit is now being considered for commercial exploitation using the in-situ leaching technology. (author)

  9. Electric power from sugar cane in Costa Rica. A technical and economic analysis

    Energy Technology Data Exchange (ETDEWEB)

    Tugwell, F.; Gowen, M.; Kenda, W.; Cohen, A.

    1988-07-01

    A team of specialists visited Costa Rica in May 1988 to analyze the potential for production and sale of electricity by the sugar-cane industry. Focusing on three sugar mills, the team made technical projections at four levels of investment, ranging from the simplest sale of surplus power to the installation of new turbogenerator systems. For each level, capital costs, electricity production and sales, and fuel options were estimated. Associated risks were assessed through sensitivity analyses to demonstrate the possible impacts of varying interest rates, fuel costs, and electricity sales prices. The team concluded that production and sale of electricity for the national grid could be an excellent investment opportunity for the sugar industry and would provide important economic benefits, including creation of additional jobs in rural areas, diversification of the sugar industry, and (in the short term) displacement of the need for imported fuels.

    The Austrian sugar industry has developed a project for the manufacture of alcohol that is geared to the conditions in that country and is based on sugar beet as raw material. An alcohol production plant could be integrated in a sugar factory and operate all the year round at a capacity of 120,000 l/d. In this factory, the fermentation raw material would be in the form of green syrup (also thick juice if the need arose) and would be supplied from other sugar factories operating without molasses. The vinasse is to be concentrated and used or burnt. The project provides new possibilities for agriculture, and the sugar industry expects an improvement in plant utilization and a diversification.

    Creating transgenic plants is invaluable for the genetic analysis of sugar beet and will be increasingly important as sugar beet genomic technologies progress. A protocol for Agrobacterium-mediated transformation of sugar beet is described in this chapter. Our protocol is optimized for a sugar beet genotype that performs exceptionally well in tissue culture, including the steps of dedifferentiation, callus proliferation, and regeneration. Because of the infrequent occurrence of such a genotype in sugar beet populations, our protocol includes an in vitro propagation method for germplasm preservation. The starting materials for transgenic experiments are aseptic shoots grown from surface-sterilized seed balls. Callus is induced from leaf explants and subsequently infected with Agrobacterium. Plantlets are regenerated from transgenic callus and vernalized for flowering, if necessary. The efficiency of transformation was quite high; in our laboratory, the culture of only ten leaf explants, on average, generated one transgenic plant. PMID:25300853

  1. Uranium-mill appraisal program

    International Nuclear Information System (INIS)

    The results of special team appraisals at NRC-licensed uranium mills in the period May to November 1981 are reported. Since the Three Mile Island accident, NRC management has instituted a program of special team appraisals of radiation protection programs at certain NRC-licensed facilities. These appraisals were designed to identify weaknesses and strengths in NRC-licensed programs, including those areas not covered by explicit regulatory requirements. The regulatory requirements related to occupational radiation protection and environmental monitoring at uranium mills have been extensively upgraded in the past few years. In addition, there was some NRC staff concern with respect to the effectiveness of NRC licensing and inspection programs. In response to this concern and to changes in mill requirements, the NRC staff recommended that team appraisals be conducted at mills to determine the adequacy of mill programs, the effectiveness of the new requirements, and mill management implementation of programs and requirements. This report describes the appraisal scope and methodology as well as summary findings and conclusions. Significant weaknesses identified during the mill appraisals are discussed as well as recommendations for improvements in uranium mill programs and mill licensing and inspection

    Full Text Available Background: Sugars that occur naturally in foods and those added in processed foods may act as the source for fermentable carbohydrates and may initiate caries process. Among all the foods consumed by children, chocolates form an important constituent. A wide variety of chocolates are available in the Indian market and very few studies have compared their acidogenicity and salivary sugar clearance. Objectives: To compare the acidogenicity and salivary sugar clearance of 6 different commercially available chocolates in the Indian market. Materials and Methods: Thirty subjects aged 10-15 years were selected randomly from one of the available public schools in Nellore city. Six commercially available chocolates in the Indian market were divided into three groups, unfilled (dark and milk chocolate, filled (wafer and fruit and nuts chocolate, and candy (hard milk and mango-flavored candy groups. Plaque pH values and salivary sugar clearance rates are assessed at baseline, 5, 10, 15, 20, and 30 min after consumption. All the data obtained were statistically evaluated using independent sample t-test and one-way ANOVA for multiple group comparisons. Results: Mango-flavored candy had maximum fall in plaque pH and least fall in plaque pH was recorded with milk chocolate. Fruit and nuts chocolate had a maximum clearance of salivary sugar and least fall in the salivary sugar clearance was recorded with dark chocolate. When the plaque pH and salivary sugar clearance of all the chocolates were assessed, it was seen that the values were statistically significant at all the time intervals (P < 0.05. Conclusion: Dark chocolate had a high fall in pH and milk chocolate had low salivary sugar clearance which signifies that unfilled chocolates are more cariogenic than other chocolates. Even though mango-flavored candy had maximum fall in plaque pH, its salivary sugar clearance was high.

    Full Text Available Jute Industrial sector is an important segment of Indian economy. Jute has been the most versatile natural fibre. The jute sector produces products ranging from low value geo-textile to high end garments, decorative, upholstery etc. Many of the jute plants or mills are now engaged in producing jute blended yarns. The jute industry scenario in India has been changed from making traditional hessian to high end fashion garments. The jute export counts to about 1000 crore, the import of raw jute has been dropped by 66 per cent in 2008-09. The Indian jute industry is having plenty of opportunity by its side; it is not only one of the oldest industries of India but also among the major employer of the nation. There are a lot of strengths and also much chance to seize them but it could only be done if it overcomes its weaknesses and threats.

    Full Text Available Environmental pollution poses a great health hazard to human beings, animals and plants. Pollution has also adverse effects on the land, water and its living and nonliving components. Industrial effluents, containing organic and inorganic compounds have strong influence on the development of growth of crop plants. The treated effluent was collected from OPM paper mill from its outlet. Thephysicochemical characteristics of paper mill industry effluent were measured and some were found to beabove the permissible limits prescribed by Indian irigation water standard. A study was conducted in pots toinvestigate the effects of different concentrations (10, 20, 30, 40, 50, 60, 70, 80 and 100% of paper mill effluenton growth and production of rice, mustard and pea for three years. The study reveals that the paper mill effluenthas deleterious effect on the growth of crop at higher concentrations. However, at lower concentration (viz. 10 to40% in rice, 10 to 50% in mustard and 10 to 60% in pea of effluent, beneficial impact on general welfare of thecrops was noticed. Growth and development was increased with increasing the concentration of the effluent upto 30% in rice, 40% in mustard and 50% in pea. Investigation showed that the growth and production of rice,mustard and pea was found maximum at a concentration of 30, 40 and 50% effluent respectively.

    Ethanol can be produced from lignocellulosic biomass with the usage of ball milling pretreatment followed by enzymatic hydrolysis and fermentation. The sugar yields from lignocellulosic feed stocks are critical parameters for ethanol production process. The research results from this paper indicated that the yields of glucose and xylose were improved by adding any of the following dilute chemical reagents: H(2)SO(4), HCl, HNO(3), CH(3)COOH, HCOOH, H(3)PO(4), and NaOH, KOH, Ca(OH)(2), NH(3)·H(2)O in the ball milling pretreatment of corn stover. The optimal enzymatic hydrolysis efficiencies were obtained under the conditions of ball milling in the alkali medium that was due to delignification. The data also demonstrated that ball milling pretreatment was a robust process. From the microscope image of ball milling-pretreated corn stover, it could be observed that the particle size of material was decreased and the fiber structure was more loosely organized. Meanwhile, the results indicate that the treatment effect of wet milling is better than that of dry milling. The optimum parameters for the milling process were ball speed of 350 r/min, solid/liquid ratio of 1:10, raw material particle size with 0.5 mm, and number of balls of 20 (steel ball, ??=?10 mm), grinding for 30 min. In comparison with water milling process, alkaline milling treatment could increase the enzymatic hydrolysis efficiency of corn stover by 110%; and through the digestion process with the combination of xylanase and cellulase mixture, the hydrolysis efficiency could increase by 160%.

    The international and Japan's steel industry, the coking coal market, and Japan's expectations from Canada's coal industry are discussed. Japan's steel mills are operating at full capacity. Crude steel production for the first half of 2004 was 55.8 million tons. The steel mills are profitable, but costs are high, and there are difficulties with procuring raw materials. Japan is trying to enhance the quality of coke, in order to achieve higher productivity in the production of pig iron. Economic growth is rising disproportionately in the BRICs (Brazil, Russia, India, and China), with a large increase in coking coal demand from China. On the supply side, there are several projects underway in Australia and Canada to increase production. These include new developments by Elk Valley Coal Corporation, Grande Cache Coal, Western Canadian Coal, and Northern Energy and Mining in Canada. The Elga Mine in the far eastern part of Russia is under development. But the market is expected to remain tight for some time. Japan envisions Canadian coal producers will provide a stable coal supply, expansion of production and infrastructure capabilities, and stabilization of price. 16 slides/overheads are included.

  17. Development of hemicelluloses biorefineries for integration into kraft pulp mills

    Science.gov (United States)

    Ajao, Olumoye Abiodun

    The development and wide spread acceptance of production facilities for biofuels, biochemicals and biomaterials is an important condition for reducing reliance on limited fossil resources and transitioning towards a global biobased economy. Pulp and paper mills in North America are confronted with high energy prices, high production costs and intense competition from emerging economies and low demand for traditional products. Integrated forest biorefineries (IFBR) have been proposed as a mean to diversify their product streams, increase their revenue and become more sustainable. This is feasible because they have access to forest biomass, an established feedstock supply chain and wood processing experience. In addition, the integration of a biorefinery process that can share existing infrastructure and utilities on the site of pulp mill would significantly lower investment cost and associated risks. Kraft pulping mills are promising receptor processes for a biorefinery because they either possess a prehydrolysis step for extracting hemicelluloses sugars prior to wood pulping or it can be added by retrofit. The extracted hemicelluloses could be subsequently transformed into a wide range of value added products for the receptor mill. To successfully implement hemicelluloses biorefinery, novel processes that are technically and economically feasible are required. It is necessary to identify products that would be profitable, develop processes that are energy efficient and the receptor mill should be able to supply the energy, chemicals and material demands of the biorefinery unit. The objective of this thesis is to develop energy efficient and economically viable hemicelluloses biorefineries for integration into a Kraft pulping process. A dissolving pulp mill was the reference case study. The transformation of hemicellulosic sugars via a chemical and biochemical conversion pathway, with furfural and ethanol as representative products for each pathway was studied. In the first part of this work, the feasibility of concentrating prehydrolysate solution with a reverse osmosis membrane was studied. The concentration step is required to reduce the energy demand of the subsequent conversion processes and the size of process equipments. Reconstituted prehydrolysate solutions containing different concentrations of glucose, xylose acetic acid, syringaldehyde and furfural was used to determine the feasibility of concentrating with a reverse osmosis membrane. The effect of the solution composition and operating conditions (cross flow velocity, temperature and pressure) on the selectivity of the membrane and the permeate flux were investigated. The results revealed that irrespective of the prehydrolysate composition, the feed pressure and temperature had the most dominant effect on the permeate flux. A permeate flux decline was observed in all experiments and the mechanisms responsible for the flux decline were elucidated. It was also confirmed that the membrane fouling is reversible and regeneration can be successfully carried out by cleaning with a sodium hydroxide solution. The second part of this work focussed on a chemical conversion pathway for furfural production. A prehydrolysate solution was generated by using a wood chips furnish that is similar to that of the reference mill and used to evaluate the membrane concentration requirements for furfural production. The retention and flux characteristics of six commercial organic membranes made from different polymers (polyamide, cellulose acetate and polypiperazine amide) and with molecular weight cut offs (MWCO) between 100 and 500 Da were evaluated. A membrane with total sugar retention of 99% and a MWCO of about 200 Da was shown to be the most suitable for a furfural process based on the criteria: low energy requirement for concentration, low degree of fouling potential and high retentions of the desired components (sugars, acetic acid and furfural). The maximum volumetric concentration factor was determined to be 4, exceeding this limit leads to increased fouling of the membran

    Pelleting of biomass can increase their bulk density and thus improve storability and reduce transportation costs. The objective of this research was to determine the effects of the pelleting conditions on chemical composition and fermentable sugar yield of the biomass. Corn stover, wheat straw, big bluestem, and sorghum stalks were used for this study. Dilute sulfuric acid was used for biomass pretreatment. Accellerase 1500™ was used for cellulose hydrolysis. Effects of mill screen size, die thickness, and L/D ratio of die on chemical compositions and sugar yield were determined. Glucan content of the biomass was positively affected by die thickness and negatively affected by mill screen size. Opposite trend was observed for xylan content. Wheat straw pellets had the highest sugar yield (92.5-94.1%) and big bluestem pellets had the lowest sugar yield (83.6-91.1%). Optimum pelleting condition is 6.5 mm screen size and 44.5 mm die thickness. PMID:21987307

  15. The "coolie curse": The evolution of white colonial attitudes towards the Indian question, 1860-1900

    Scientific Electronic Library Online (English)

    Duncan, Du Bois.

    Full Text Available Neither by accident nor design, Natal became home to over 50 000 Indian immigrants during the latter half of the nineteenth century. At the request of fewer than 50 sugar planters, colonial Natal embarked on a labour dispensation which was initially envisaged as "an experiment," on a small scale, as [...] Governor John Scott saw it. Appreciated for their contribution as labourers to the success of sugar production, Indians nonetheless, were resented by white colonists as settlers after they had completed their indenture contracts. That resentment was heightened by the influx of traders and non-indentured Indians into Natal after 1875 and found expression in published opinion and in discriminatory legislation. By the 1890s Natal's anti-Indian legislation became an imperial controversy which also proved life-changing for M.K. Gandhi. This article attempts to track the evolution of white settler attitudes to what was termed the "coolie curse."

    2006-03-01

    Full Text Available During the last fi ve years the sugar industry has become one of the most important branches of Croatian food industry. It is connected with a signifi cant number of various industries in a complex way and employs a signifi cant number of people. A development of the sugar industry stimulates development of commerce, logistics, and a number of correlated industries whose products are necessary in sugar production. Croatian sugar factories have been present at the neighbouring markets and the European Union market for several years. Th e share of sugar in the total export of agricultural products increases every year and in the year 2004, it was 26.8% with the tendency of increasing in the year 2005. Th e foundation of the Intellectual capital (IC concept, as a method of increasing the entire business effi ciency, can be found in the papers of economic theoreticians in the middle of the last century but it reached its real break through in the past 15 years when the concept got more applied and the theory of intellectual capital was developed. In order to prepare Croatian economy for the competition that is expecting Croatia by joining the European Union with full membership, especially the agricultural sector, the application of the IC concept is expected to result with an increase of business effi ciency. Th e intellectual capital concept represents a recommended base, which will help Croatian sugar mills in achieving a better position at the highly competitive market of the European Union.

    Full Text Available Mechanical alloying has recently attracted considerable attention as researchers strive to enhance nanocomposite properties and extend their utility. The process can be performed at room temperature and homogeneous nanocomposite powders can be produced. In this paper, we investigated the effect of different ball milling parameters and operating conditions (milling time, ball size, processing control agent (PCA and speed in mechanical alloying of aluminum powder to achieve particle size reduction with less contamination. Two types of PCA, i.e. stearic acid and methanol have been used and microstructure evolutions at different operating conditions were studied. It was shown that the optimized milling parameters for aluminium composite are 100 stainless steel ball (10 mm, 200 rpm rotation speed with direction reversal and 1 min pause time after every 15 min running time, under argon gas for 30 hr of milling.

  1. Underground milling of uranium ores

    International Nuclear Information System (INIS)

    Full text: This paper presents and analyzes the new concept of underground milling of high-grade uranium ore. Compared to conventional milling on surface, the underground milling scheme appears to offer significant cost savings and a lower environmental impact. The paper describes the underground milling scheme, presents process flowsheets and plant layouts, and provides an assessment of potential benefits from underground milling. In response to the current supply/demand situation for uranium, there has been, for the past few years, a 'uranium rush' in many parts of the world, including the resource-rich Athabasca basin situated in northern Saskatchewan. In a recent count, there were over forty uranium companies looking for uranium in this region. Positive results from any of these exploration activities could, depending on their location, potentially provide a source of additional feedstock for any of the existing milling centres in northern Saskatchewan and/or result in the establishment of additional new milling capacity. Underground milling would be considered in the latter instance. The above flowsheet shows the basics of the proposed underground milling scheme, which assumes the existence of a high-grade underground uranium mine, similar to the current McArthur River mine or the planned Cigar Lake mine. Grinding, leaching, solid/liquid separation and tailings deposition are all carried out underground. Leach liquor is pumped to surface for impurity removal, precipitation and drying. The impurities, removed as chemical precipitates, are moved back underground for disposal. Expected environmental benefits are significant and include reduction of surface visual impact, leach residues remain underground, and no tailings management facility on surface. Indeed the process residue is arguably more isolated from the environment than was the ore before mining. Contaminant transport from the stored tailings to surface waters is extremely slow. Application of membrane technology to water treatment for the underground milling scheme is expected to provide an aqueous effluent with minimal loading to the environment. In addition to these substantial environmental benefits, underground milling is expected to give a capital cost saving on the order of 35% and an operating cost saving on the order of 30% relative to conventional mining and milling.

  10. Inorganic elements in sugar samples

    International Nuclear Information System (INIS)

    Sugar is considered a safe food ingredient; however, it can be contaminated by organic elements since its planting until its production process. Thus, this study aims at checking the presence of inorganic elements in samples of crystal, refined and brown sugar available for consumption in Brazil. The applied technique was neutron activation analysis, the k0 method, using the TRIGA MARK - IPR-R1 reactor located at CDTN/CNEN, in Belo Horizonte. It was identified the presence of elements such as, Au, Br, Co, Cr, Hf, K, Na, Sb, Sc and Zn in the samples of crystal/refined sugar and the presence of As, Au, Br, Ca, Co, Cr, Cs, Fe, Hf, K, Na, Sb, Sc, Sm, Sr, Th and Zn in the brown sugar samples. The applied technique was appropriate to this study because it was not necessary to put the samples in solution, essential condition in order to apply other techniques, avoiding contaminations and sample losses, besides allowing a multi elementary detection in different sugar samples.

    A facile butanol bioproduction process was developed using planetary milling, and Pinus rigida wood waste as a model substrate for fermentable sugars. The use of planetary milling as the pretreatment eliminates the need for washing and transfer of the biomass prior to enzymatic hydrolysis. Moreover, using this pretreatment process resulted in the production of only 0.072±0.003g/L soluble phenolic compounds, a concentration that was not inhibitory towards Clostridium beijerinckii NCIMB 8052. As the milling was performed in a compatible buffer (50mM acetate, pH 4.8), the enzymatic hydrolysis step was initiated by simply adding the cellulase cocktail powder directly to pretreated biomass without washing the biomass or exchanging the buffer, resulting in a glucose yield of 31g/L (84.02%). Fermentation of the hydrolysate samples by C. beijerinckii NCIMB 8052 gave slightly better butanol yields than cultures grown in a typical lab media (P2), with final concentrations of 6.91and 6.66g/L, respectively.

  12. Effect of steam pretreatment on oil palm empty fruit bunch for the production of sugars

    International Nuclear Information System (INIS)

    Lignocellulose into fuel ethanol is the most feasible conversion route strategy in terms of sustainability. Oil palm empty fruit bunch (EFB) generated from palm oil production is a huge source of cellulosic material and represents a cheap renewable feedstock which awaits further commercial exploitation. The purpose of this study was to investigate the feasibility of using steam at 0.28 MPa and 140 °C generated from the palm oil mill boiler as a pretreatment to enhance the digestibility of EFB for sugars production. The effects of steam pretreatment or autohydrolysis on chemical composition changes, polysaccharide conversion, sugar production and morphology alterations of four different types of EFB namely fresh EFB (EFB1), sterilized EFB (EFB2), shredded EFB (EFB3) and ground EFB (EFB4) were evaluated. In this study, the effects of steam pretreatment showed major alterations in the morphology of EFB as observed under the scanning electron microscope. Steam pretreated EFB2 was found to have the highest total conversion of 30% to sugars with 209 g kg−1 EFB. This production was 10.5 fold higher than for EFB1 and 1.6 fold and 1.7 fold higher than EFB3 and EFB4, respectively. The results suggested that pretreatment of EFB by autohydrolysis using steam from the mill boiler could be considered as being a suitable pretreatment process for the production of sugars. These sugars can be utilized as potential substrates for the production of various products such as fuel ethanol. -- Highlights: ► We investigate the feasibility of steam pretreatment to enhance digestibility of EFB. ► Steam pretreatment increased sugars to 3.4 fold and caused major alteration in EFB morphology under SEM. ► Autohydrolysis which does not require the addition of chemicals is an attractive pretreatment approach to EFB.

  13. Synthesis of the Sugar Moieties

    Grynkiewicz, Grzegorz; Szeja, Wieslaw

    Biological activity of the anthracycline antibiotics, which have found wide application in clinical oncology, is strongly related to their glycosidic structure. Modification or switch of the saccharide moiety became an important line of new drug discovery and study of their mechanism of action. Natural glycons (sugar moieties) of the anthracycline antibiotics belong to the 2,6-dideoxypyranose family and their principal representative, daunosamine, is 3-amino-2,3,6-trideoxy- l-lyxo-pyranose. Some newer chemical syntheses of this sugar, from a chiral pool as well as from achiral starting materials, are presented and their capability for scale-up and process development are commented upon. Rational sugar structural modifications, which are either useful for synthetic purposes or offer advantages in experimental therapy of cancer, are discussed from the chemical point of view.

  14. Uranium mill tailings management

    International Nuclear Information System (INIS)

    The tailings produced as a result of uranium mining and milling operations contain large quantities of radioactive material albeit at concentrations only slightly above that occurring naturally. Due to the fact that the material has been brought to the surface and has been physically and chemically changed, radioactive and other constituents are now more mobile and available for uptake in food chains etc. The large volumes of material and the long half-lives of the radionuclides present make it impossible to completely isolate the material from the environment. Releases to the environment must however be controlled to limit exposures of the public to acceptable levels. This lecture discusses the sources of radioactivity in tailings material and the most important release mechanisms i.e. seepage, erosion, gaseous emanation and particulate suspension by which the radioactivity can escape to the environment. The possible critical pathways by which man can be exposed and its dependence on climatic factors are described and management options for controlling these releases are mentioned. Finally, the existing legislation in South Africa for the control of these releases are discussed and the release rate limits applied in various countries are given

  16. Production of sugar and sugar derivatives by pyrolysis of biomass

    Energy Technology Data Exchange (ETDEWEB)

    Shafizadeh, F.

    1983-01-01

    Thermochemical conversion of biomass to sugar and sugar derivatives is hindered by the inhomogeneity of the substrate and the low specificity of the pyrolytic reactions. Recent analysis and investigation of these reactions have shown that they could be controlled and catalyzed to minimize the side reactions and increase the yield of individual compounds. These compounds include levoglucosan which could be obtained in high yields within the temperature range of 350-400/sup 0/C when the substrate has undergone previous acid treatment or a trace amount of acid is present. This phenomenon has been used for production of sugars from softwood and hardwood based on prehydrolysis and subsequent pyrolysis to a tar that could be posthydrolyzed to sugars. Acid-catalyzed pyrolysis of cellulosic materials, particularly waste paper, gives a pyrolyzate containing mainly levoglucosenone which has proved to be a highly reactive compound for production of a variety of carbohydrate derivatives. Pyrolysis of carbohydrates also provides several other furan and pyran derivatives that could be used as synthetic intermediates. 28 references, 22 figures, 11 tables.

  17. Pyrolytic sugars from cellulosic biomass

    Science.gov (United States)

    Kuzhiyil, Najeeb

    Sugars are the feedstocks for many promising advanced cellulosic biofuels. Traditional sugars derived from starch and sugar crops are limited in their availability. In principle, more plentiful supply of sugars can be obtained from depolymerization of cellulose, the most abundant form of biomass in the world. Breaking the glycosidic bonds between the pyranose rings in the cellulose chain to liberate glucose has usually been pursued by enzymatic hydrolysis although a purely thermal depolymerization route to sugars is also possible. Fast pyrolysis of pure cellulose yields primarily levoglucosan, an anhydrosugar that can be hydrolyzed to glucose. However, naturally occurring alkali and alkaline earth metals (AAEM) in biomass are strongly catalytic toward ring-breaking reactions that favor formation of light oxygenates over anhydrosugars. Removing the AAEM by washing was shown to be effective in increasing the yield of anhydrosugars; but this process involves removal of large amount of water from biomass that renders it energy intensive and thereby impractical. In this work passivation of the AAEM (making them less active or inactive) using mineral acid infusion was explored that will increase the yield of anhydrosugars from fast pyrolysis of biomass. Mineral acid infusion was tried by previous researchers, but the possibility of chemical reactions between infused acid and AAEM in the biomass appears to have been overlooked, possibly because metal cations might be expected to already be substantially complexed to chlorine or other strong anions that are found in biomass. Likewise, it appears that previous researchers assumed that as long as AAEM cations were in the biomass, they would be catalytically active regardless of the nature of their complexion with anions. On the contrary, we hypothesized that AAEM can be converted to inactive or less active salts using mineral acids. Various biomass feedstocks were infused with mineral (hydrochloric, nitric, sulfuric and phosphoric acids) and organic acids (formic and acetic acids) followed by analytical pyrolysis on a micropyrolyzer/GC/MS/FID system. It was found that sulfuric and phosphoric acids are very effective in passivating the AAEM thereby increasing the yield of anhydrosugars. An excellent correlation was discovered between the amount of acid required to obtain the maximum yield of anhydrosugars and the amount of AAEM contained in the biomass feedstock. In the micro-scale studies, up to 56% of the cellulose contained in the biomass was converted into anhydrosugars which is close to the 57% conversion obtained from pure cellulose pyrolysis. It is known that LG polymerization and subsequent charring occur at temperatures above 275°C depending on the vapor pressure of LG in the gas stream. A study of pyrolysis of acid-infused biomass feedstocks at various temperatures revealed that LG recovery is best at lower temperatures than the conventional pyrolysis temperature range of 450-500°C. Pyrolysis of acid-infused biomass failed in a continuous fluidized bed reactor due to clogging of the bed. The feedstock formed vitreous material along with the fluidizing sand that was formed from poor pyrolysis of lignin. However, more investigation of this phenomenon is a subject for future work. Pyrolysis experiments on an auger type reactor were successful in producing bio-oils with unprecedented amounts of sugars. Though there was increase in charring when compared to the control feedstock, pyrolysis of red oak infused with 0.4 wt% of sulfuric acid produced bio-oil with 18wt% of sugars. One of the four fractions of bio-oil collected contained most of the sugars, which shows significant potential for separating the sugars from bio-oil using simple means. This work points towards a new pathway for making advanced biofuels viz. upgrading pyrolytic sugars from biomass that could compete with enzymatic sugars from biomass.

  18. SUBAQUEOUS DISPOSAL OF MILL TAILINGS

    Energy Technology Data Exchange (ETDEWEB)

    1999-09-03

    A study of mill tailings and sulfide minerals was carried out in order to understand their behavior under subaqueous conditions. A series of electrochemical experiments, namely, cyclic voltammetry, electrochemical impedance spectroscopy and galvanic coupling tests were carried out in artificial seawater and in pH 6.8 buffer solutions with chloride and ferric salts. Two mill tailings samples, one from the Kensington Mine, Alaska, and the other from the Holden Mine, Washington, were studied along with pyrite, galena, chalcopyrite and copper-activated sphalerite. SEM analysis of mill tailings revealed absence of sulfide minerals from the Kensington Mine mill tailings, whereas the Holden Mine mill tailings contained approximately 8% pyrite and 1% sphalerite. In order to conduct electrochemical tests, carbon matrix composite (CMC) electrodes of mill tailings, pyrite and galena were prepared and their feasibility was established by conducting a series of cyclic voltammetry tests. The cyclic voltammetry experiments carried out in artificial seawater and pH 6.8 buffer with chloride salts showed that chloride ions play an important role in the redox processes of sulfide minerals. For pyrite and galena, peaks were observed for the formation of chloride complexes, whereas pitting behavior was observed for the CMC electrodes of the Kensington Mine mill tailings. The electrochemical impedance spectroscopy conducted in artificial seawater provided with the Nyquist plots of pyrite and galena. The Nyquist plots of pyrite and galena exhibited an inert range of potential indicating a slower rate of leaching of sulfide minerals in marine environments. The galvanic coupling experiments were carried out to study the oxidation of sulfide minerals in the absence of oxygen. It was shown that in the absence of oxygen, ferric (Fe3+) ions might oxidize the sulfide minerals, thereby releasing undesirable oxidation products in the marine environment. The source of Fe{sup 3{minus}} ions may be attributed to iron-bearing sulfide (and oxide) minerals present in the mill tailings. However, the concentration of available Fe{sup 3{minus}} ions can be reduced by the precipitation of insoluble ferric hydroxides (Fe(OH ){sub 3}) by seawater due to its near neutral pH. In such case, the oxidation of a sulfide mineral is inhibited due to the absence of an oxidizing agent (viz. oxygen and/or Fe{sup 3+} ions). The experiments carried out in this study provided a better understanding of behavior of sulfide minerals and mill tailings in subaqueous conditions and may be useful for further investigation of sulfide minerals and mill tailings in other environments.

    2012-12-26

    Molasses, the main byproduct of sugar production, is a well-known source of antioxidants. In this study sugar cane molasses (SCM) and sugar beet molasses (SBM) were investigated for their phenolic profile and in vitro antioxidant capacity and for their protective effect in human HepG2 cells submitted to oxidative stress. According to its higher phenolic concentration and antioxidant capacity in vitro, SCM exhibited an effective protection in cells, comparable to or even greater than that of ?-tocopherol. Data herein reported emphasize the potential health effects of molasses and the possibility of using byproducts for their antioxidant activity. This is particularly important for consumers in developing countries, as it highlights the importance of consuming a low-price, yet very nutritious, commodity. PMID:23190112

  20. YANG-MILLS FIELD CAPACITOR

    Directory of Open Access Journals (Sweden)

    Trunev A. P.

    2015-10-01

    Full Text Available The article presents a project of the capacitor in the Yang-Mills theory. Model capacitor represents the equipotential surfaces separated by a space. To describe the mechanism of condensation chromodynamics field used numerical models developed based on an average of the Yang-Mills theory. In the present study, we used eight-scalar component model that in the linear case is divided into two groups containing three or five fields respectively. In contrast to classical electrodynamics, a static model of the Yang-Mills is not divided into independent equations because of the nonlinearity of the model itself. However, in the case of a linear theory separation is possible. It is shown that in this particular case, the Yang-Mills theory is reduced to Poisson theory, which describes the electrostatic and magnetostatic phenomena. In the present work it is shown that in a certain region of the parameters of the capacitor of the Yang-Mills theory on the functional properties of the charge accumulation and retention of the field is similar to the capacitor of the electrostatic field or a magnet in magnetostatics. This means that in nature there are two types of charges, which are sources of macroscopic Yang-Mills field, which are similar to the properties of electric and magnetic charges in the Poisson theory. It is shown that in Yang-Mills only one type of charge may be associated with the distribution density of the substance, while another type of charge depends on the charge distribution of the first type. This allows us to provide an explanation for the lack of symmetry between electric and magnetic charges

  8. La science politique de John Stuart Mill

    Directory of Open Access Journals (Sweden)

    Frederick Rosen

    2008-02-01

    Full Text Available This essay explores aspects of John Stuart Mill’s approach to social and political science in the Considerations on Representative Government (1861 with an emphasis on the significance of character or ‘ethology’ in this science. The starting point is a discussion of psychology and ethology in Book VI of the Logic (1843. This conception is examined in terms of Mill’s framework of inductive and deductive science and the distinction between art and science where the views of Mill and Jeremy Bentham are contrasted. Given Mill’s view of the relationship between art and science, the science of ethology (including political ethology assumes a more prominent position in Mill’s thought than any political art or any distinctly political science. Contrary to many commentators, it is argued that Mill never abandoned his commitment to ethology, as is clear from the discussion of ‘the ideally best form of government’ in the Considerations. Mill’s conception of ‘active character’ here underpins and directs what might otherwise be seen as a traditional account of forms of government. The cultivation of active character becomes an essential condition for the success of representative government. The essay concludes with remarks on Mill’s emphasis on society for his account of liberty in On Liberty (1859 and suggests that he considered new ways of understanding the traditional processes of government.

  9. Natural radionuclides as dirt tracers in sugar cane consignments

    International Nuclear Information System (INIS)

    Soil is usually carried out to the mills, as an impurity in sugar cane, leading to economic drawbacks for the industry. The quantification of this dirt is important to identify its causes and for routine quality control. Several methods have been used for this purpose, however, no single one has been pointed out as an industrial standard. The use of a ?-ray emitting radionuclide of natural occurence was investigated and, after several soil and cane radioactivity analyses, 212Pb was chosen as the best tracer. Calibration curves developed with the addition of soil in clean cane, from 0 to 10% (dry mass), demonstrated the linearity of the method. Analyses of eleven samples taken from consignments showed that the procedure was consistent and reliable when compared to the traditional ash method. (author)

The predominant noise sources need to be identified and the causes of high noise need to be studied to undertake the appropriate measures to reduce the noise level in one of the major agro-based industries, oil mills. Aims: To identify the predominant noise sources in the workrooms of oil mills. To study the causes of noise in oil mills. To measure the extent of noise exposure of oil mill workers. To examine the response of workers towards noise, so that appropriate measures can be undertaken to minimize the noise exposure. Settings and Design: A noise survey was conducted in the three renowned oil mills of north-eastern region of India. Materials and Methods: Information like output capacity, size of power source, maintenance condition of the machines and workroom configurations of the oil mills was collected by personal observations and enquiry with the owner of the mill. Using a Sound Level Meter (SLM (Model-824, Larson and Davis, USA, equivalent SPL was measured at operator′s ear level in the working zone of the workers near each machine of the mills. In order to study the variation of SPL in the workrooms of the oil mill throughout its operation, equivalent SPL was measured at two appropriate locations of working zone of the workers in each mill. For conducting the noise survey, the guidelines of Canadian Centre for Occupational Health and Safety (CCOHS were followed. Grid points were marked on the floor of the workroom of the oil mill at a spacing of 1 m x 1 m. SPL at grid points were measured at about 1.5 m above the floor. The direction of the SLM was towards the nearby noisy source. To increase accuracy, two replications were taken at each grid point. All the data were recorded for 30 sec. At the end of the experiment, data were downloaded to a personal computer. With the help of utility software of Larson and Davis, USA, equivalent SPL and noise spectrum at each reading was obtained. Noise survey map of equivalent SPL was drawn for each oil mill by drawing contour lines on the sketch of the oil mill between the points of equal SPL. The floor area in the oil mill where SPL exceeded 85 dBA was identified from the noise survey map of each oil mill to determine the causes of high level of noise. Subjective assessment was done during the rest period of workers and it was assessed with personal interview with each worker separately. Demographic information, nature of work, working hours, rest period, experience of working in the mill, degree of noise annoyance, activity interference, and psychological and physiological effects of machine noise on the worker were asked during the interview. These details were noted in a structured form. Statistical Analysis Used: Nil. Results: The noise survey conducted in three renowned oil mills of north-eastern region of India revealed that about 26% of the total workers were exposed to noise level of more than 85 dBA. Further, 10% to 30% floor areas of workrooms, where oil expellers are provided have the SPL of more than 85 dBA. The noise in the oil mills was dominated by low frequency noise. The predominant noise sources in the oil mills were seed cleaner and power transmission system to oil expellers. Poor maintenance of machines and use of bamboo stick to prevent the fall of belt from misaligned pulleys were the main reason of high noise. Noise emitted by the electric motor, table ghani and oil expellers in all the oil mills was well within 85 dBA. Subjective response indicated that about 63% of the total workers felt that noise interfered with their conversation. About 16% each were of the opinion that noise interfered in their work and harmed their hearing. About 5% of workers stated that the workroom noise gave them headaches. Conclusions: The workers engaged in the workrooms of the oil mills are exposed to high noise, which will have detrimental effect on their health. The poor maintenance of drive system was found to be the main reason for high noise level.

  12. Critical management issues for the Uranium Mill Tailings Remedial Action (UMTRA) Project

    International Nuclear Information System (INIS)

    The Uranium Mill Tailings Radiation Control Act of 1978 (PL95-604) authorized the Secretary of Energy to enter into cooperative agreements with certain states and Indian Tribes to clean up 24 inactive uranium mill tailing sites and associated vicinity properties. The Uranium Mill Tailings Remedial Action (UMTRA) Project includes the three Federal agencies (EPA, DOE, and NRC), eleven state, Indian Tribes, and at least four major contractors. The UMTRA Project extends over a period of ten years. The standards for the Project require a design life of 1000 years with a minimum performance period of 200 years. This paper discusses the critical management issues in dealing with the UMTRA Project and identifies the development of solutions for many of those issues. The highlights to date are promulgation of EPA standards, continued support from Congress and participating states and Indian Tribes, significant leadership shown at all levels, establishment of credibility with the public, and continued motivation of the team. The challenge for tomorrow is making certain NRC will license the sites and maintaining the high level of coordination exhibited to date to assure Project completion on schedule

    2003-07-01

    In the present work, a cogeneration system of sugar-alcohol cane mill is evaluated. Using the Exergetic Cost Theory, a thermo economic analysis is made for the crop corresponding to the year 2000. Previously a detailed energetic analysis was made in order to determine of the first law efficiency for steam boilers and the fuel consumption involved. The first and second law equipment's efficiencies were calculated as well as some performance criteria of the overall system. The fundamental aim of the evaluation was to obtain the cost of the principal fluxes of the system, considering a discount rate of 15 % and a capital recovery period of fifteen years for the energetic equipment in the sugar mill for the monetary cost calculations. In the analysis, was included the sugar mill juice extraction system as a control volume in order to determine the variation in the bagasse cost and its influence in the cost of other fluxes. A Thermodynamic analysis is also made, in which the increase of thermodynamic parameters is studied as a way of improving the fuel economy in Sugar Mill Factories focusing the electric energy obtained in the different alternatives. Diverse strategies are discussed, and as a result, the thermodynamic evaluations of two Proposals of Steam Cogeneration Systems are accomplished as well as the calculations of the exergetic cost.

  3. Saccharification of recalcitrant biomass and integration options for lignocellulosic sugars from Catchlight Energy’s sugar process (CLE Sugar

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Abstract Background Woody biomass is one of the most abundant biomass feedstocks, besides agriculture residuals in the United States. The sustainable harvest residuals and thinnings alone are estimated at about 75 million tons/year. These forest residuals and thinnings could produce the equivalent of 5 billion gallons of lignocellulosic ethanol annually. Softwood biomass is the most recalcitrant biomass in pretreatment before an enzymatic hydrolysis. To utilize the most recalcitrant lignocellulosic materials, an efficient, industrially scalable and cost effective pretreatment method is needed. Results Obtaining a high yield of sugar from recalcitrant biomass generally requires a high severity of pretreatment with aggressive chemistry, followed by extensive conditioning, and large doses of enzymes. Catchlight Energy’s Sugar process, CLE Sugar, uses a low intensity, high throughput variation of bisulfite pulping to pretreat recalcitrant biomass, such as softwood forest residuals. By leveraging well-proven bisulfite technology and the rapid progress of enzyme suppliers, CLE Sugar can achieve a high yield of total biomass carbohydrate conversion to monomeric lignocellulosic sugars. For example, 85.8% of biomass carbohydrates are saccharified for un-debarked Loblolly pine chips (softwood, and 94.0% for debarked maple chips (hardwood. Furan compound formation was 1.29% of biomass feedstock for Loblolly pine and 1.10% for maple. At 17% solids hydrolysis of pretreated softwood, an enzyme dose of 0.075 g Sigma enzyme mixture/g dry pretreated (unwashed biomass was needed to achieve 8.1% total sugar titer in the hydrolysate and an overall prehydrolysate liquor plus enzymatic hydrolysis conversion yield of 76.6%. At a much lower enzyme dosage of 0.044 g CTec2 enzyme product/g dry (unwashed pretreated softwood, hydrolysis at 17% solids achieved 9.2% total sugar titer in the hydrolysate with an overall sugar yield of 85.0% in the combined prehydrolysate liquor and enzymatic hydrolysate. CLE Sugar has been demonstrated to be effective on hardwood and herbaceous biomass, making it truly feedstock flexible. Conclusions Different options exist for integrating lignocellulosic sugar into sugar-using operations. A sugar conversion plant may be adjacent to a CLE Sugar plant, and the CLE Sugar can be concentrated from the initial 10% sugar as needed. Concentrated sugars, however, can be shipped to remote sites such as ethanol plants or other sugar users. In such cases, options for shipping a dense form of sugars include (1 pretreated biomass with enzyme addition, (2 lignocellulosic sugar syrup, and (3 lignocellulosic sugar solid. These could provide the advantage of maximizing the use of existing assets.

  4. Fossil energy savings potential of sugar cane bio-energy systems

    DEFF Research Database (Denmark)

    2009-01-01

    One important rationale for bio-energy systems is their potential to save fossil energy. Converting a conventional sugar mill into a bio-energy process plant would contribute to fossil energy savings via the extraction of renewable electricity and ethanol substituting for fossil electricity and gasoline, respectively. This paper takes a closer look at the Thai sugar industry and examines two practical approaches that will enhance fossil energy savings. The first one addresses an efficient extraction of energy in the form of electricity from the excess bagasse and cane trash. The second while proposing to convert molasses or sugar cane to ethanol stresses the use of bagasse as well as distillery spent wash to replace coal in meeting ethanol plants' energy needs. The savings potential achieved with extracting ethanol from surplus sugar versus current practice in sugar industry in Thailand amounts to 15 million barrels of oil a year. Whether the saving benefits could be fully realized, however, depends on how well the potential land use change resulting from an expansion of ethanol production is managed. The results presented serve as a useful guidance to formulate strategies that enable optimum utilization of biomass as an energy source

    2015-01-01

    We investigate the symmetry structure of the non-relativistic limit of Yang-Mills theories. Generalising previous results in the Galilean limit of electrodynamics, we discover that for Yang-Mills theories there are a variety of limits inside the Galilean regime. We first explicitly work with the $SU(2)$ theory and then generalise to $SU(N)$ for all $N$, systematising our notation and analysis. We discover that the whole family of limits lead to different sectors of Galilean Yang-Mills theories and the equations of motion in each sector exhibit hitherto undiscovered infinite dimensional symmetries, viz. infinite Galilean Conformal symmetries in $D=4$. These provide the first examples of interacting Galilean Conformal Field Theories (GCFTs) in $D>2$.

  7. ONLINE SAG MILL PULSE MEASUREMENT AND OPTIMIZATION

    Energy Technology Data Exchange (ETDEWEB)

    Raj Rajamani; Jose Delgadillo; Vishal Duriseti

    2006-06-24

    The grinding efficiency of semi autogenous milling or ball milling depends on the tumbling motion of the total charge within the mill. Utilization of this tumbling motion for efficient breakage of particles depends on the conditions inside the mill. However, any kind of monitoring device to measure the conditions inside the mill shell during operation is virtually impossible due to the severe environment presented by the tumbling charge. An instrumented grinding ball, which is capable of surviving a few hours and transmitting the impacts it experiences, is proposed here. The spectrum of impacts collected over 100 revolutions of the mills presents the signature of the grinding environment inside mill. This signature could be effectively used to optimize the milling performance by investigating this signature's relation to mill product size, mill throughput, make-up ball size, mill speed, liner profile and ball addition rates. At the same time, it can also be used to design balls and liner systems that can survive longer in the mill. The technological advances made in electronics and communication makes this leap in instrumentation certainly viable. Hence, the instrumented grinding ball offers the ability to qualitatively observe and optimize the milling environment.

  9. Stable isotope studies of Indian rivers

    International Nuclear Information System (INIS)

    To understand the surface water characteristics in India, the nine most important rivers have been sampled around the sub-continent. Both Oxygen 18 and Deuterium have been measured to determine the origin of the water and the possible evaporation process. Also the main ions have been analyzed to obtain complementary information. Where some basins have been previously studies, mainly in the North, this is a first attempt at a wider investigation of Indian rivers. If we compare our results with the mean isotopic variation of rainfall over Indian as seen from the GNIP data set, a general NW/ SE isotopic gradient is revealed. The west coast and the south part of Dekkan are the least depleted in heavy isotopes, with a ?18O values of between 0 and -2 per mille, and this relate to the Kaveri, Nethvrati and Krishna rivers. The area below the Thar desert displays a ?18O value of around -3 per mille, as in the Narmada and Tapti rivers. The central part of the Dekkan and the east coast are characterised by ?18O values of around -5 per mille, like for the Godavari and Mahanadi rivers. The North India big plains present ?18O value of between -6 and -12 per mille, like for the Ganga and Brahmaputra rivers. For the Ganga and the Brahmaputra rivers, the seasonal effect is stronger due to significant variations in different water sources i.e.: i) perennial tributaries coming from the inland hills, or the ground water discharge, which contributes water moderately depleted in 18O (winter and spring), ii) Himalayan tributaries fed by snow and glacier melt which are very depleted in heavy isotopes (sommer and fall), and iii) the heavy monsoon rainfall (early summer) which can travel deep inland more lighter water. As seen from the slope of the ?18O and ?2H regression and the calculation of the deuterium excess, the water of these rivers evaporates only slightly during the wet monsoon season (June-September). Evaporation could be more intense before in the hot and dry season (April-May), as seen from sampling on the Yamuna River, the main tributary of the Ganga. Better understanding the characteristics and water origin of these rivers will help to improve the management of the substantial water needs (potable water, irrigation, industry) of this expanding country. But also it can contribute to our understanding of means of flood control, drought prevention, hydroelectric power generation, and improvements in environmental quality

  11. The chemistry of uranium milling

    International Nuclear Information System (INIS)

    The major stages in conventional processes for the milling of uranium ores are the leaching of the uranium by acid or alkaline solutions, concentration and purification by solvent extraction or ion-exchange, and precipitation. The chemistry of uranium through-out these key stages is discussed, as well as the relationship between mineralogy and chemistry in pretreatment and leaching stages. The behavior of vandium, which is an important byproduct in many mills, is also discussed. The chemistry of uranium in alternative processes for uranium recovery is briefly reviewed, e.g. in bacterial leaching, heap leaching, solution mining, production of uranium tetrafluoride instead of yellowcake, and recovery from phosphate liquors.

    The major health hazard from uranium mill tailings is presumed to be respiratory cancer resulting from the inhalation of radon daughter products. A review of studies on inhalation of radon and its daughters indicates that the hazard from the tailings is extremely small. If the assumptions used in the studies are correct, one or two people per year in the United States may develop cancer as a result of radon exhaled from all the Uranium Mill Tailings Remedial Action program sites. The remedial action should reduce the hazard from the tailings by a factor of about 100

    Full Text Available The article presents a project of the Yang-Mills amplifier. Amplifier model is a multilayer spherical shell with increasing density towards the center. In the center of the amplifier is the core of high-density material. It is shown that in such a system, the amplitude of the Yang-Mills waves rises from the periphery to the center of several orders of magnitude. The role of the Yang-Mills field in the processes occurring in the nuclei of galaxies, stars and planets is discussed. The data modeling to strengthen the Yang-Mills field in the bowels of the planet, with an atomic explosion, and in some special devices such as the voltaic pile. To describe the mechanism of amplification chromodynamics field used as accurate results in Yang-Mills theory and numerical models developed based on an average and the exact equations as well. Among the exact solutions of the special role played by the centralsymmetric metric describing the contribution of the Yang-Mills field in the speed of recession of galaxies. Among the approximate numerical models can be noted the eight-scalar model we have developed for the simulation of non-linear color oscillations and chaos in the Yang-Mills theory. Earlier models were investigated spatio-temporal oscillations of the YangMills theory in the case of three and eight colors. The results of numerical simulation show that the nonlinear interaction does not lead to a spatial mixing of colors as it might be in the case of turbulent diffusion. Depending on the system parameters there is a suppression of the amplitude of the oscillations the first three by five colors or vice versa. The kinetic energy fluctuations or shared equally between the color components, or dominated by the kinetic energy of repressed groups of colors. In the present study, we found that amplification chromodynamic field leads to a sharp increase in the amplitude of the suppressed color, which can lead to an increase in entropy, excitation of nuclear reactions and decays particles

    No organism lives in a constant environment. Based on classical studies in molecular biology, many have viewed microbes as following strict rules for shifting their metabolic activities when prevailing conditions change. For example, students learn that the bacterium Escherichia coli makes proteins for digesting lactose only when lactose is available and glucose, a better sugar, is not. However, recent studies, including three PLOS Biology papers examining sugar utilization in the budding yeast Saccharomyces cerevisiae, show that considerable heterogeneity in response to complex environments exists within and between populations. These results join similar recent results in other organisms that suggest that microbial populations anticipate predictable environmental changes and hedge their bets against unpredictable ones. The classical view therefore represents but one special case in a range of evolutionary adaptations to environmental changes that all organisms face. PMID:25688600

    Full Text Available The highest expense on sugarcane management is fertilization in which one of them is phosphate fertilizer produced by imported raw materials. An innovation was made by using the local phosphate deposits with low reactivity processed further to improve their effectiveness for sugarcane. The objective of this study was to investigate the growth, yield and quality of sugarcane as affected by bio-superphosphate (Bio-SP application on a highly weathered tropical soil. A nine-month field experiment was conducted at Jatitujuh Sugar Mill area, West Java, Indonesia, comparing between sugarcane fertilized with Bio-SP to replace conventional single superphosphate (SP-36 and that fertilized with SP-36. Urea and MOP (Muriate of Potash were applied at similar dosages as recommended by division of Jatitujuh Sugar Mill Agronomy Research. Bio-SP was formulated by reacting a Central Java Rock Phosphate with liquid culture supernatant (LCS and phosphoric acid characterized by 33% total soluble P2O5, 23.1, and 10.7 % citric acid and water-soluble P2O5, respectively. The results indicated that Bio-SP at 50% dosage of SP-36 was as effective as the SP-36 in supporting sugarcane growth and improved yield up to 8% as crystal sugar. Further consequence of this finding is that the application of Bio-SP reduced 9.2% of fertilizer cost for sugarcane.

    In this work, a non-enzymatic chemiresistive sugar sensor has been developed by combining a synthetic receptor with aligned single-walled carbon nanotubes (SWNTs) device. Briefly, boronic acid as a multivalent sugar receptor was immobilized on carbon nanotubes through amide bond formation. The interaction between three common sugars (d-glucose, d-fructose and sucrose) and boronic acid modified SWNTs device was studied. The effect of pH on the receptor-ligand binding was examined and highest response was observed at pH 9. The chemiresistive sensor exhibited specific and reproducible detection with sensitivity over the concentration range of 1-20mM, 1-25 mM, and 1-30 mM for fructose, glucose, and sucrose, respectively. The sensor showed no interference from common electroactive compounds such as citric acid, uric acid, and ascorbic acid. Furthermore, the sensor retained 97.4% of the initial value after five regeneration cycles with an acidic buffer at pH 5, thus ensuring good reusability. PMID:25059188

    2001-05-01

    A comparative analysis of the production and processing of sugar beet and sugar cane in Morocco was carried out with regards to energy and water use. Total agricultural energy inputs for sugar beet were 33.79 GJ/ha and in the case of sugar cane were 59.33 GJ/ha for plant cane and 35.65 GJ/ha for ratoons. The major energy inputs for both were diesel fuel, electricity and fertilisers. In sugar beet production fertiliser application accounted for move than 50% of total agricultural energy inputs. The most energy intensive operations in sugar cane production were irrigation (37%) and fertiliser application (29%). The input:output energy ratios were 1:3.2 for sugar beet and 1:3.7 for sugar cane. Total energy used in processing was 26.19 GJ/tonne white sugar (tws) from sugar beet and 3.02 GJ/tws from sugar cane. Direct energy in processing was 22.51 GJ/tws for sugar beet and 1.27 GJ/tws for sugar cane. Overall (production + processing) input:output energy ratio was 1:1.5 for sugar beet and 1:4.2 for sugar cane. Overall analysis demonstrated that the production of sugar from sugar beet is more energy intensive than from sugar cane while the sugar cane requires larger inputs of water. (author)

    Directory of Open Access Journals (Sweden)

    Joner Oliveira Alves

    2014-10-01

    Full Text Available The increased demand for energy from sugarcane bagasse has made the sugar and alcohol mills search alternatives to reduce maintenance of the boilers, releasing more time to the production. The stainless steel use has become one of the main tools for such reduction. However, specification errors can lead to premature failures. This work reports the factors that led tubes of AISI 409 stainless steel fail after half season when applied in a air preheater of boiler from a sugarcane mill. In such application, the AISI 304 lasts about 15 seasons and the carbon steel about 3. A tube sent by the sugar mill was characterized by wet chemical analysis, optical microscopy and EDS. Results indicated chloride formation on the internal walls of the tube, which combined with the environment, accelerated the corrosion process. The carbon steel showed high lifetime due to a 70% higher thickness. Due to the work condictions is recommended the use of stainless steels with higher corrosion resistance, such as the traditional AISI 304 or the ferritic AISI 444, the last presents better thermal exchange.

    Directory of Open Access Journals (Sweden)

    Yoney López

    2010-09-01

    Full Text Available The chemical composition of rice hulls produced in an artisan mill and its conversion to fermentable sugars was investigated. The carbohydrate fraction represented 59.2% (w/w of the dry hulls. Cellulose, with 36.6%, was the main component, followed by xylan with 13.9%. An important contribution of starch (8.7% was also detected. The content of ash (19.6% and lignin (15.5% was comparable with that of rice hulls obtained in industrial mills. Dilute-sulphuric acid hydrolysis at different temperatures, from 160 to 210°C, was evaluated for production of fermentable sugars. Due to starch hydrolysis, the concentration of glucose in the hydrolysates produced at 160°C was higher than the values that have previously been reported for industrial sorts of rice hulls under comparable conditions. The xylan-to-xylose conversion increased steadily with increase of the temperature and reached a maximum (67.7% at 190°C. Further increases of the hydrolysis temperature decreased the yield of sugars due to their dehydration to furfural and HMF.

    Full Text Available Ethanol production for fuel is important for the Brazilian economy as a renewable solution to oil derivatives. Theindustrial process uses commercially available yeast, most of them isolated from sugar mills from the Brazilian stateof São Paulo. The research information on the availability of yeast appropriate to the climatic conditions occurringin the Midwest region of Brazil is scarce. The article presents the isolation and morphological characterization offermentative wild yeast prospected on the sugar cane juice of a sugar and alcohol mill of Mato Grosso State. Thejuice samples were collected in both the hot and rainy (HR season and in the cold and dry (CD one. The dilutedsugar cane juice samples were plated on agar LWYN and evaluated for fermentation in test tubes containinginverted Durham tubes. From 26 morphotypes isolated, 50% were able to ferment sugar cane juice. Greater numberand diversity of yeasts was found in both December (HR and July (CD. In the remaining months of each seasonthere were a low number of colonies with a poor diversity.

  3. Sugar recognition by human galactokinase

    Directory of Open Access Journals (Sweden)

    Timson David J

    2003-11-01

    Full Text Available Abstract Background Galactokinase catalyses the first committed step of galactose catabolism in which the sugar is phosphorylated at the expense of MgATP. Recent structural studies suggest that the enzyme makes several contacts with galactose – five side chain and two main chain hydrogen bonds. Furthermore, it has been suggested that inhibition of galactokinase may help sufferers of the genetic disease classical galactosemia which is caused by defects in another enzyme of the pathway galactose-1-phosphate uridyl transferase. Galactokinases from different sources have a range of substrate specificities and a diversity of kinetic mechanisms. Therefore only studies on the human enzyme are likely to be of value in the design of therapeutically useful inhibitors. Results Using recombinant human galactokinase expressed in and purified from E. coli we have investigated the sugar specificity of the enzyme and the kinetic consequences of mutating residues in the sugar-binding site in order to improve our understanding of substrate recognition by this enzyme. D-galactose and 2-deoxy-D-galactose are substrates for the enzyme, but N-acetyl-D-galactosamine, L-arabinose, D-fucose and D-glucose are all not phosphorylated. Mutation of glutamate-43 (which forms a hydrogen bond to the hydroxyl group attached to carbon 6 of galactose to alanine results in only minor changes in the kinetic parameters of the enzyme. Mutation of this residue to glycine causes a ten-fold drop in the turnover number. In contrast, mutation of histidine 44 to either alanine or isoleucine results in insoluble protein following expression in E. coli. Alteration of the residue that makes hydrogen bonds to the hydroxyl attached to carbons 3 and 4 (aspartate 46 results in an enzyme that although soluble is essentially inactive. Conclusions The enzyme is tolerant to small changes at position 2 of the sugar ring, but not at positions 4 and 6. The results from site directed mutagenesis could not have been predicted from the crystal structure alone and needed to be determined experimentally.

  4. Effects of compost application on fruits yields, sugar and mineral contents and δ15N values of tomato fruits

    International Nuclear Information System (INIS)

    We examined the effects of chemical fertilizer and compost application on the yields and sugar and mineral content of tomato (Lycopersicon esculentum Mill. Saturn) in an isolated bed. Five treatments were conducted within a two-year period of 4 continuous croppings. CDU and LSR (Low-sulfate slow-release fertilizer) were used for the chemical fertilizer plots. A mixture of cattle manure and CDU (CM + CDU), a mixture of poultry manure and CDU (PM + CDU), and mixture of cattle and poultry manure (PM + CM) plots were arranged as compost-using plots. We also measured the δ15N values of tomatoes and the soils of each treatment, and estimated the correlation of the δ15N values between fruits and soil to certify compost applied products. We did not find any reproductive differences in the yield or sugar content among the treatments. As to inorganic content of tomatoes, there were no significant differences except for Mg content among the plots. These results showed that it is difficult to assay regular benefit of organic fertilizer application to tomato yields and quality. On the other hand, δ15N values of tomato fruits showed significant differences among fertilizer applications. δ15N values of the chemical fertilizer were +1.6 per mille and -1.1% for CDU and LSR, respectively. Those of mixture of chemical and compost were +12.2 per mille and +11.2 per mille for CM + CDU and PM + CDU, respectively. The mixture of PM and CM showed the highest δ15N values (17.9 per mille) among the treatments. δ15N values of the soils and fruits reflected those of the fertilizers and were positively correlated (R2 = 0.89). It may be possible to use δ15N values as an indicator of organic products by setting the threshold point, e.g. +5.0 per mille, to distinguish them from the products cultivated with chemical fertilizer.

    The boundaries of three major plates (Africa, India, and Antarctica) meet in a triple junction in the Indian Ocean near 25 /sup 0/S, 70 /sup 0/E. Using observed bathymetry and magnetic anomalies, we locate the junction to within 5 km and show that it is a ridge-ridge-ridge type. Relative plate motion is N60 /sup 0/E at 50 mm/yr (full rate) across the Central Indian Ridge, N47 /sup 0/E at 60 mm/yr across the Southeast Indian Ridge, and N3 /sup 0/W at 15 mm/yr across te Southwest Indian Ridge; the observed velocity triangle is closed. Poles of instantaneous relative plate motion are determined for all plate pairs. The data in the South Atlantic and Indian oceans are consistent with a rigid African plate without significant internal deformation. Two of the ridges at the triple junction are normal midocean spreading centers with well-defined median valleys. The Southwest Indian Ridge, however, has a peculiar morphology near the triple junction, that of an elongate triangular deep, with the triple junction at its apex. The floor of the deep represents crust formed at the Southwest Indian Ridge, and the morphology is a consequence of the evolution of the triple junction and is similar to that at the Galapagos Triple Junction. Though one cannot determine with precision the stability conditions at the triple junction, the development of the junction over the last 10 m.y. can be mapped, and the topographic expressions of the triple junction traces may be detected on the three plates.

However after diagnostic tests and image improvements, the number of reports has shortened. A possible explanation for this shortage is the identification of other diseases that could mimic the clinical picture. Currently, the syndrome has an uncertain nosological status, since it was described based on clinical examination only.

    Zirconia ceramics has found applications in various important fields. Oxygen sensors, heating elements, solid electrolytes, cutting tools, high temperature insulation, metal casting dies and nozzles are some of the areas of applications. Milling of zirconia compositions should preferably be done with ZrO2 milling media. Moreover, higher density of ZrO2 (5.5-5.7 gm/cc.) compared to alumina (3.4-3.7 gm/cc) results in faster grinding by zirconia balls. Wear of the grinding jar is also less compared to alumina balls. In the present work grinding balls have been prepared from zirconia, Y2O3, CaO-TiO2 stabilizing agents. (author). 6 refs., 2 figs., 1 tab

    Apart from political influences, energy balances and economic calculations seem to be determining factors in the decision to produce ethanol from sugar cane and beet. The energy balances for cane and beet sugar to ethanol are positive. The price of ethanol from sugar cane and beet give satisfactory results in comparison with that from crude oil. When unmarketable sugar is available at a low price in developing countries, it seems attractive to produce ethanol in order to reduce oil imports.

  19. Sugar cane/sweet sorghum as an ethanol feedstock in Louisiana and Piedmont

    International Nuclear Information System (INIS)

    Cost to provide readily fermentable feedstock for a year round sweet sorghum-to-ethanol production facility, up to the point at which fermentation begins, was determined. It was assumed that sweet sorghum is produced on marginal crop lands in the Southeastern Piedmont, and is purchased, standing in the field by a central ethanol production facility. Feedstock cost varied from $1.96 to $2.98/gal of ethanol potential depending on harvest system and use of by-products. Major contributors to feedstock cost were field production, harvest/field processing, and cost to evaporate juice to a storable syrup. Cost to transport feedstock to a central production facility, and cost of storage were relatively minor components of total cost, contributing only $0.05 and $0.06/gal ethanol potential, respectively. For a point of comparison, cost of producing ethanol feedstock from sugar cane, based on current processing practices in Louisiana sugar mills, was determined to be $2.50/gal ethanol potential. This cost is higher than determined for most options in the Piedmont for two reasons: (1) sugar cane demands a higher price in Louisiana than was assumed for sweet sorghum in the Piedmont, and (2) little market exists in Louisiana for by-products of sugar milling, consequently, no by-product credit was assigned. Current market value of ethanol must approximately double before a sweet sorghum-to-ethanol industry in the Piedmont could be economically viable, as no opportunity was identified for a significant reduction in feedstock cost

    The prospects for life in the Universe just got sweeter, with the first discovery of a simple sugar molecule in space. The discovery of the sugar molecule glycolaldehyde in a giant cloud of gas and dust near the center of our own Milky Way Galaxy was made by scientists using the National Science Foundation's 12 Meter Telescope, a radio telescope on Kitt Peak, Arizona. "The discovery of this sugar molecule in a cloud from which new stars are forming means it is increasingly likely that the chemical precursors to life are formed in such clouds long before planets develop around the stars," said Jan M. Hollis of the NASA Goddard Space Flight Center in Greenbelt, MD. Hollis worked with Frank J. Lovas of the University of Illinois and Philip R. Jewell of the National Radio Astronomy Observatory (NRAO) in Green Bank, WV, on the observations, made in May. The scientists have submitted their results to the Astrophysical Journal Letters. "This discovery may be an important key to understanding the formation of life on the early Earth," said Jewell. Conditions in interstellar clouds may, in some cases, mimic the conditions on the early Earth, so studying the chemistry of interstellar clouds may help scientists understand how bio-molecules formed early in our planet's history. In addition, some scientists have suggested that Earth could have been "seeded" with complex molecules by passing comets, made of material from the interstellar cloud that condensed to form the Solar System. Glycolaldehyde, an 8-atom molecule composed of carbon, oxygen and hydrogen, can combine with other molecules to form the more-complex sugars Ribose and Glucose. Ribose is a building block of nucleic acids such as RNA and DNA, which carry the genetic code of living organisms. Glucose is the sugar found in fruits. Glycolaldehyde contains exactly the same atoms, though in a different molecular structure, as methyl formate and acetic acid, both of which were detected previously in interstellar clouds. Glycolaldehyde is a simpler molecular cousin to table sugar, the scientists say. The sugar molecule was detected in a large cloud of gas and dust some 26,000 light-years away, near the center of our Galaxy. Such clouds, often many light-years across, are the material from which new stars are formed. Though very rarified by Earth standards, these interstellar clouds are the sites of complex chemical reactions that occur over hundreds of thousands or millions of years. So far, about 120 different molecules have been discovered in these clouds. Most of these molecules contain a small number of atoms, and only a few molecules with eight or more atoms have been found in interstellar clouds. The 12 Meter Telescope "Finding glycolaldehyde in one of these interstellar clouds means that such molecules can be formed even in very rarified conditions," said Hollis. "We don't yet understand how it could be formed there," he added. "A combination of more astronomical observations and theoretical chemistry work will be required to resolve the mystery of how this molecule is formed in space." "We hope this discovery inspires renewed efforts to find even more kinds of molecules, so that, with a better idea of the total picture, we may be able to deduce the details of the prebiotic chemistry taking place in interstellar clouds," Hollis said. The discovery was made by detecting faint radio emission from the sugar molecules in the interstellar cloud. Molecules rotate end-for-end, and as they change from one rotational energy state to another, they emit radio waves at precise frequencies. The "family" of radio frequencies emitted by a particular molecule forms a unique "fingerprint" that scientists can use to identify that molecule. The scientists identified glycolaldehyde by detecting six frequencies of radio emission in what is termed the millimeter-wavelength region of the electromagnetic spectrum -- a region between more-familiar microwaves and infrared radiation.

    Full Text Available Since the early Colonial times sugar production has been a key sector in the Peruvian export economy. This article analyzes its evolution as from the beginning of its modern phase by mid 19th Century, its consolidation in the Northern coastal region, and its concentration in scale-economy plants. The prosperity of this type of production contributed to the formation of both an oligarchy which governed the country until 1968, and the populist party (APRA and its electoral basis (the so-called «Aprista North». In the sixties Velasco Alvarado’s military revolution nationalized the sugar industry, which underwent structural changes leading to a serious crisis in the eighties that has not been overcome up-todate.

    Energy is a crucial input for the economic and social development of any nation. Both renewable and non-renewable energy contribute in meeting the total requirement of the economy. As an affordable and clean energy source, wind energy is amongst the world's fastest growing renewable energy forms. Though there are several wind-mill clusters producing energy in different geographical locations, evaluating their performance is a complex task and not much of literature is available in this area. In this backdrop, an attempt is made in the current paper to estimate the performance of a wind-mill cluster through an index called Cluster Performance Index (CPI) adopting a multi-criteria approach. The proposed CPI comprises four criteria viz., Technical Performance Indicators (TePI), Economic Performance Indicators (EcPI), Environmental Performance Indicators (EnPI), and Sociological Performance Indicators (SoPI). Under each performance criterion a total of ten parameters are considered with five subjective and five objective oriented responses. The methodology is implemented by collecting empirical data from three wind-mill clusters located at Chitradurga, Davangere, and Gadag in the southern Indian State of Karnataka. Totally fifteen different stake holders are consulted through a set of structured researcher administered questionnaire to collect the relevant data in each wind farm. Stake holders involved engineers working in wind farms, wind farm developers, Government officials from energy department and a few selected residential people near the wind farms. The results of the study revealed that Chitradurga wind farm performed much better with a CPI of 45.267 as compared to Gadag (CPI of 28.362) and Davangere (CPI of 19.040) wind farms. (Author)

  6. Online SAG Mill Pluse Measurement and Optimization

    Energy Technology Data Exchange (ETDEWEB)

    Raj Rajamani; Jose Delgadillo; Vishal Duriseti

    2007-06-30

    The grinding efficiency of semi autogenous milling or ball milling depends on the tumbling motion of the total charge within the mill. Utilization of this tumbling motion for efficient breakage of particles depends on the conditions inside the mill. However, any kind of monitoring device to measure the conditions inside the mill shell during operation is virtually impossible due to the severe environment presented by the tumbling charge. An instrumented grinding ball, which is capable of surviving a few hours and transmitting the impacts it experiences, is proposed here. The spectrum of impacts collected over 100 revolutions of the mills presents the signature of the grinding environment inside mill. This signature could be effectively used to optimize the milling performance by investigating this signature's relation to mill product size, mill throughput, make-up ball size, mill speed, liner profile and ball addition rates. At the same time, it can also be used to design balls and liner systems that can survive longer in the mill. The technological advances made in electronics and communication makes this leap in instrumentation certainly viable. Hence, the instrumented grinding ball offers the ability to qualitatively observe and optimize the milling environment. An instrumented load cell package that can measure the force of impacts inside the grinding chamber of a mill is developed here. The signal from the instrumented load cell package is interpreted in terms of a histogram termed as an impact spectrum which is a plot of the number of impacts at a specific energy level against the energy. It reflects on the average force regime of the mill. The instrumented load cell package was calibrated against the ultra fast load cell which has been unanimously accepted as a standard to measure single breakage events. The load cell package was successfully used to produce impact spectra in an 8.5 inch lab scale mill. The mill speed and the ball size were varied to study their effect on the impact spectra. A good correlation was found between the process variables and the impact spectra. The load cell package was then used in a 16 inch pilot scale mill. The mill speed, ball size, and mill filling were varied here and a consistent trend between these variables and impact spectra was observed. With a better understanding developed from the initial tests, the design of the load cell package was significantly changed to eliminate noise. With the new design, the impact spectra were re-determined in the 16 inch pilot mill varying the process variables - ball size, mill speed, and mill filling. Finally, it is successfully shown that a change in the operating variables of a mill can be seen in the impact spectra and that this concept can be successfully developed to monitor the grinding operation of industrial mills. To adapt it to industrial level it is mandatory to make the load cell package wireless. A design of a wireless circuit that is capable of transferring data at the required speed of 1000 kbps was also developed and tested at Cortez Gold Mines (CGM), Nevada.

  14. Indian Ocean Traffic: Introduction

    Directory of Open Access Journals (Sweden)

    Lola Sharon Davidson

    2012-06-01

    Full Text Available Like the Mediterranean, the Indian Ocean has been a privileged site of cross-cultural contact since ancient times. In this special issue, our contributors track disparate movements of people and ideas around the Indian Ocean region and explore the cultural implications of these contacts and their role in processes that we would come to call transnationalization and globalisation. The nation is a relatively recent phenomenon anywhere on the globe, and in many countries around the Indian Ocean it was a product of colonisation and independence. So the processes of exchange, migration and cultural influence going on there for many centuries were mostly based on the economics of goods and trade routes, rather than on national identity and state policy.

    In this study we investigated the technical feasibility of convert paper mill sludge into fuel ethanol. This involved the removal of mineral fillers by using either chemical pretreatment or mechanical fractionation to determine their effects on cellulose hydrolysis and fermentation to ethanol. In addition, we studied the effect of cationic polyelectrolyte (as accelerant) addition and hydrogen peroxide pretreatment on enzymatic hydrolysis and fermentation. We present results showing that removing the fillers content (ash and calcium carbonate) from the paper mill sludge increases the enzymatic hydrolysis performance dramatically with higher cellulose conversion at faster rates. The addition of accelerant and hydrogen peroxide pretreatment further improved the hydrolysis yields by 16% and 25% (g glucose / g cellulose), respectively with the de-ashed sludge. The fermentation process of produced sugars achieved up to 95% of the maximum theoretical ethanol yield and higher ethanol productivities within 9h of fermentation. PMID:26086086

  17. Microbiological Spoilage of High-Sugar Products

    Science.gov (United States)

    Thompson, Sterling

    The high-sugar products discussed in this chapter are referred to as chocolate, sugar confectionery (non-chocolate), liquid sugars, sugar syrups, and honey. Products grouped in the sugar confectionery category include hard candy, soft/gummy candy, caramel, toffee, licorice, marzipan, creams, jellies, and nougats. A common intrinsic parameter associated with high-sugar products is their low water activity (a w), which is known to inhibit the growth of most spoilage and pathogenic bacteria. However, spoilage can occur as a result of the growth of osmophilic yeasts and xerophilic molds (Von Richter, 1912; Anand & Brown, 1968; Brown, 1976). The a w range for high-sugar products is between 0.20 and 0.80 (Banwart, 1979; Richardson, 1987; Lenovich & Konkel, 1992; ICMSF, 1998; Jay, Loessner, & Golden, 2005). Spoilage of products, such as chocolate-covered cherries, results from the presence of yeasts in the liquid sugar brine or the cherry. Generally, the spoiled product will develop leakers. The chocolate covering the cherry would not likely be a source of yeast contamination.

  1. Mechanical alloying and reactive milling in a high energy planetary mill

    International Nuclear Information System (INIS)

    Powder refinement in a planetary mill (Retsch PM 400-MA) is investigated experimentally and analyzed using discrete element modeling (DEM). Refinement is defined as the average size of the individual components in a composite powder. The specific milling dose, defined as the product of charge ratio and milling time, is used as an experimental parameter tracking the progress of the material refinement. This parameter is determined experimentally for milling of boron and titanium powders, for which the time of initiation of a self-sustained reaction is measured under different milling conditions. It is assumed that the reaction becomes self-sustaining when the same powder refinement is achieved. The DEM calculations established that the milling balls primarily roll along the milling container's perimeter. The inverse of the rate of energy dissipation resulting from this rolling motion is used as the DEM analog of the specific milling dose. The results correlate well with experimental observations.

    2016-04-01

    This study describes a time and energy saving, solvent-free procedure for the conversion of lignocellulosic barley straw into reducing sugars by mechanocatalytical pretreatment. The catalytic conversion efficiency of several solid acids was tested which revealed oxalic acid dihydrate as a potential catalyst with high conversion rate. Samples were mechanically treated by ball milling and subsequently hydrolyzed at different temperatures. The parameters of the mechanical treatment were optimized in order to obtain sufficient amount of total reducing sugar (TRS) which was determined following the DNS assay. Additionally, capillary electrophoresis (CE) and Fourier transform infrared spectrometry (FT-IR) were carried out. Under optimal conditions TRS 42% was released using oxalic acid dihydrate as a catalyst. This study revealed that the acid strength plays an important role in the depolymerization of barley straw and in addition, showed, that the oxalic acid-catalyzed reaction generates low level of the degradation product 5-hydroxymethylfurfural (HMF).

  7. Fructose-containing sugars and cardiovascular disease.

    Science.gov (United States)

    Rippe, James M; Angelopoulos, Theodore J

    2015-07-01

    Cardiovascular disease (CVD) is the single largest cause of mortality in the United States and worldwide. Numerous risk factors have been identified for CVD, including a number of nutritional factors. Recently, attention has been focused on fructose-containing sugars and their putative link to risk factors for CVD. In this review, we focus on recent studies related to sugar consumption and cardiovascular risk factors including lipids, blood pressure, obesity, insulin resistance, diabetes, and the metabolic syndrome. We then examine the scientific basis for competing recommendations for sugar intake. We conclude that although it appears prudent to avoid excessive consumption of fructose-containing sugars, levels within the normal range of human consumption are not uniquely related to CVD risk factors with the exception of triglycerides, which may rise when simple sugars exceed 20% of energy per day, particularly in hypercaloric settings.

  11. Indian Jute in Australian Collections: Forgetting and Recollecting Transnational Networks

    Directory of Open Access Journals (Sweden)

    Andrew Hassam

    2011-12-01

    Full Text Available Indian jute sacking played an essential role in Australian life for over 150 years, yet its contribution to Australian development and its Indian origins have been barely recognised in Australian public collections. What has Australian history gained by this erasing of jute from public memory? Wool, sugar and hop sacks are displayed in public collections as evidence of an Australian national story, but their national dimension depends on the cultural invisibility of jute and jute’s connections to the stories of other communities in other places. Developing an awareness of the contribution of Indian jute to the development of Australia requires an awareness not simply that jute comes from India but that the construction of national identity by collecting institutions relies on forgetting those transnational connections evident in their own collections. Where jute sacks have been preserved, it is because they are invested with memories of a collective way of life, yet in attempting to speak on behalf of the nation, the public museum denies more multidimensional models of cultural identity that are less linear and less place-based. If Indian jute is to be acknowledged as part of ‘the Australian story’, the concept of an Australian story must change and exhibitions need to explore, rather than ignore, transnational networks.

  12. Overview of uranium mill tailings remedial action project of the United States of America 1995-1996

    International Nuclear Information System (INIS)

    From the early 1940's through the 1960's the United States federal government contracted for processed uranium ore for national defense research, weapons development and commercial nuclear energy. When these contracts were terminated, the mills ceased operation leaving large uranium tailings on the former mill sites. The purpose of the Uranium Remedial Action Project (UMTRA) is to minimize or eliminate potential health hazards resulting from exposure of the public to the tailings at these abandons sites. There are 24 inactive uranium mill tailings sites, in 10 states and an Indian reservation lands, included for clean up under the auspices of UMTRA. Presently the last 2 sites are under remediation. This paper addresses the progress of the project over the last two years. (author)

  13. Yang-Mills Instanton Sheaves

    CERN Document Server

    Lai, Sheng-Hong; Tsai, I-Hsun

    2016-01-01

    The SL(2,C) Yang-Mills instanton solutions constructed recently by the biquaternion method were shown to satisfy the complex version of the ADHM equations and the Monad construction. Moreover, we discover that, in addition to the holomorphic vector bundles on CP^3 similar to the case of SU(2) ADHM construction, the SL(2,C) instanton solutions can be used to explicitly construct instanton sheaves on CP^3. Presumably, the existence of these instanton sheaves is related to the jumping lines of the SL(2,C) instantons on S^4 which do not exist for SU(2) instantons.

    2011-11-01

    The uranium industry in the American Southwest has had profoundly negative impacts on American Indian communities. Navajo workers experienced significant health problems, including lung cancer and nonmalignant respiratory diseases, and psychosocial problems, such as depression and anxiety. There were four uranium processing mills and approximately 1,200 uranium mines on the Navajo Nation's over 27,000 square miles. In this paper, a chronology is presented of how uranium mining and milling impacted the lives of Navajo workers and their families. Local community leaders organized meetings across the reservation to inform workers and their families about the relationship between worker exposures and possible health problems. A reservation-wide effort resulted in activists working with political leaders and attorneys to write radiation compensation legislation, which was passed in 1990 as the Radiation Exposure Compensation Act (RECA) and included underground uranium miners, atomic downwinders, and nuclear test-site workers. Later efforts resulted in the inclusion of surface miners, ore truck haulers, and millworkers in the RECA Amendments of 2000. On the Navajo Nation, the Office of Navajo Uranium Workers was created to assist workers and their families to apply for RECA funds. Present issues concerning the Navajo and other uranium-impacted groups include those who worked in mining and milling after 1971 and are excluded from RECA. Perceptions about uranium health impacts have contributed recently to the Navajo people rejecting a resumption of uranium mining and milling on Navajo lands. PMID:21979550

  1. Palm Oil Milling Wastes and Sustainable Development

    Directory of Open Access Journals (Sweden)

    Full Text Available Problem statement: Palm oil milling generates solid wastes, effluent and gaseous emissions. The aim of this study is to assess the progress made in waste management by the Malaysian palm oil milling sector towards the path of sustainable development. Sustainable development is defined as the utilization of renewable resources in harmony with ecological systems. Inclusive in this definition is the transition from low value-added to higher value-added transformation of wastes into resources. Approach: A longitudinal study was carried out from 2003-2010 via, initially a field survey and subsequently a key informant approach with observation as a complementation for both. Results: Solid wastes, inclusive of solid wastes derived from air emissions and palm oil mil effluent, have a utility function with zero wastage. The principal source of effluent is palm oil mill effluent. Treated palm oil mill effluent is utilized for cropland application by plantation-based palm oil mills. However, independent mills discharge treated palm oil mill effluent in accordance to environmental parameters into receiving waterways. Methane is also released by palm oil mill effluent. Biogas from palm oil mill effluent and biomass energy from solid wastes are potential sources of renewable energy in Malaysia. Conclusion: In general, the wastes from palm oil milling are returned to the field for cropland application, utilized in-house or in the plantation, or sold to third parties. Thus, there is progress made towards sustainable development. The addition of new technologies and replacement of old mills will help to reduce the carbon footprint. However, at this juncture, the feed-in tariff for renewable energy is not financially attractive. If the biogas and biomass renewable energy sector were to take-off, enhancement in the value chain would occur and in tandem further progress towards sustainable development can be attained.

    The sugar and ethanol production is one of the most important economical activities in Brazil, mainly due its high efficiency and competitiveness. The ethanol production is done by several steps: juice extraction, treatment, fermentation and distillation. The juice extraction and treatment is a common operation of both industries sugar and alcohol. The process begins with the sugar cane juice extraction, usually done by devices namely mills, where the cane is compressed between big cylinders for the separation of the juice from the bagasse. Recently, another juice extraction system named diffuser was introduced in some sugar and alcohol factories. On diffusers, after sugar cane preparation stage, done with knives and shredders, it passes through a bed, where the juice is separated from bagasse by the addition of imbibition water and steam, in a lixiviation process. This study evaluates two possibilities of decrease the thermal energy consumption through exergetic cost analysis. The first case, a traditional ethanol production plant is assessed, determining the unitary exergetic cost of ethanol and electrical energy, in the following case, second and third, two proposals were assessed: use of the diffuser as a extraction system and use of pinch technology to perform a energetic integration between distillation and extraction (diffuser) systems. The results of exergetic efficiency, irreversibility generation and unitary exergetic cost of products of the three cases are analyzed and compared. The results shows the validate of the use of diffuser and pinch technology on the decrease of the thermal energy consumption in the ethanol production plant. (author)

    2015-12-01

    Full Text Available The European sugar market is changing its character. During the last two decades its concentration changed and individual countries and companies have been preparing themselves for the end of sugar production quotas system. The level of competition within the EU sugar market is accelerating. Many companies already left the EU market or significantly reduced their production capacities. The main task of this material is to analyse the EU sugar market and especially sugar quotas character and to specify the current EU sugar production structures existing under the sugar quotas system. The paper is also identifying individual drivers/actors operating under the sugar quota system. The idea is to identify the level of EU sugar market concentration through the Herfindahl-Hirschman Index (HHI. The results coming from the analyses provides the overview of very specific character of the European sugar production quota system. However the market is operated by many companies and alliances, its production capacity are extremely concentrated. The majority of sugar plants are located in Germany, France, Poland and the majority of sugar quotas are controlled by companies headquartered in Germany, France, the Netherlands and the United Kingdom. In nowadays - the sugar quota system in the European Union is operated/controlled by only a few very powerful operators: Su?dzucker, Nordzucker, Tereos, ABF, Pfeifer & Langen, Royal Cosun and Cristal Union.

  14. Electron beam processing of sugar cane bagasse to cellulose hydrolysis

    International Nuclear Information System (INIS)

    Sugarcane bagasse has been considered as a substrate for single cell protein, animal feed, and renewable energy production. Sugarcane bagasse generally contain up to 45% glucose polymer cellulose, 40% hemicelluloses, and 20% lignin. Pure cellulose is readily depolymerised by radiation, but in biomass, the cellulose is intimately bonded with lignin, that protect it from radiation effects. The objective of this study is the evaluation of the electron beam irradiation as a pre-treatment to enzymatic hydrolysis of cellulose in order to facilitate its fermentation and improves the production of ethanol biofuel. Samples of sugarcane bagasse were obtained in sugar/ethanol Iracema Mill sited in Piracicaba, Brazil, and were irradiated using Radiation Dynamics Electron Beam Accelerator with 1.5 MeV energy and 37kW, in batch systems. The applied absorbed doses of the fist sampling, Bagasse A, were 20 kGy, 50 kGy, 100 kGy and 200 kGy. After the evaluation the preliminary obtained results, it was applied lower absorbed doses in the second assay: 5 kGy, 10 kGy, 20 kGy, 30 kGy, 50 kGy, 70 kGy, 100 kGy and 150 kGy. The electron beam processing took to changes in the sugarcane bagasse structure and composition, lignin and cellulose cleavage. The yield of enzymatic hydrolyzes of cellulose increase about 40 % with 30 kGy of absorbed dose. (author)

    The experimental question is whether or not sugar can be a substance of abuse and lead to a natural form of addiction. “Food addiction” seems plausible because brain pathways that evolved to respond to natural rewards are also activated by addictive drugs. Sugar is noteworthy as a substance that releases opioids and dopamine and thus might be expected to have addictive potential. This review summarizes evidence of sugar dependence in an animal model. Four components of addiction are analyzed....

  17. Sustainability Issues and Opportunities in the Sugar and Sugar-Bioproduct Industries

    Directory of Open Access Journals (Sweden)

    Gillian Eggleston

    2015-09-01

    Full Text Available Like many other industries, the sugar and sugar-bioproduct industries are facing important sustainability issues and opportunities. The relatively low and fluctuating profit for sugar, surpluses of sugar, world-wide trend to produce alternative, renewable bio-based fuels and chemicals to those derived from petroleum and reduce greenhouse gases, water- and energy-intensive factories and refineries, and increased consumer demands for sustainably manufactured products are putting pressure on the industries to diversify for sustainability. Sugar crops, including sugar and energy cane (Saccharum officinarum, sugar and energy beets (Beta vulgaris, and sweet sorghum (Sorghum bicolor L. Moench, are excellent, renewable biomass feedstocks because of their availability, their being amongst the plants that give the highest yields of carbohydrates per hectare, and high sugar contents. While much research has been focused on conversion technologies for advanced biofuels and bioproducts, attention is now focused on developing sustainable supply chains of sugar feedstocks for the new, flexible biorefineries, with customers wanting maximum feedstock reliability and quality, while minimizing cost. All biomass from sugar crops are potential feedstocks. The cogeneration of bioelectricity from bagasse and leaf residues is being increasingly manufactured in more countries and, due to the high carbon content of bagasse and leaves, can also be converted into value-added products such as biochar. Sugar crops are superior feedstocks for the production of platform chemicals for the manufacture of a range of end-products, e.g., bioplastics, chemicals, and biomaterials. In several countries and regions, green sustainability criteria are now in place and have to be met to count against national biofuel targets. Processes to convert high-fiber sugar crop biomass into biofuel have been developed but there has only been limited commercialization at the large-scale.

Chapel Hill: University of North Carolina Press, 2004. xiii + 347 pp. (Paper US $ 22.50 These two books illustrate the fascination that sugar, slavery, and the plantation still exercise over the minds of scholars. One of them also reflects an interest in the influence these have had on the modern world. For students of the history of these things the Schwartz collection is in many ways the more useful. It seeks to fill a lacuna left by the concentration of monographs on the eighteenth and nineteenth centuries, suggesting that we know less about the history of sugar than we thought we did. Perhaps in no other single place is such a range of information on so wide an area presented in such detail for so early a period. Ranging from Iberia to the Caribbean and including consumption as well as production of sugar, with a nod to the slave trade and a very useful note on weights and currencies, this volume is a gold mine of information. It considers (briefly the theoretical meaning as well as the growing of this important crop, contrasting its production in Iberia with that on the Atlantic islands of Madeira and the Canaries, colonized by Iberian powers, and continuing the contrast with São Tomé, off the coast of Africa, and on to Brazil and the Spanish American empire before ending with the British in Barbados. In the transit, it of necessity considers and complicates the meaning of “sugar revolution” and shows how scholars using that term do not always mean the same thing. John McCusker and Russell Menard, for example, tackling a cornerstone of the traditional interpretation of the development of sugar, argue that there was no “sugar revolution” in Barbados; economic change had already begun before sugar’s advent, though sugar may have accelerated it, and yet sugar production was transformed on the island. They also undercut, without quite denying, the significance of the Dutch role in the process. Schwartz, while questioning, lings to the traditional expression if not the traditional outlook, seeing in Barbados “the beginning of the sugar revolution” (p. 10.

    Merriam, Marshal L.

    1993-01-01

    Surface acquisition deals with the reconstruction of three dimensional objects from a set of data points. The most straightforward techniques require human intervention, a time consuming proposition. It is desirable to develop a fully automated alternative. Such a method is proposed in this paper. It makes use of surface measurements obtained from a 3-D laser digitizer - an instrument which provides the (x,y,z) coordinates of surface data points from various viewpoints. These points are assembled into several partial surfaces using a visibility constraint and a 2-D triangulation technique. Reconstruction of the final object requires merging these partial surfaces. This is accomplished through a procedure that emulates milling, a standard machining operation. From a geometrical standpoint the problem reduces to constructing the intersection of two or more non-convex polyhedra.

Calculations to define the effects on the environment of two types of effluents (the leaching effluent without treatment and the same after treating it) on two points of the rivers net, are given and the results discussed. A disposal policy for a treated effluent of mean composition is presented, based on two different amounts for the two phases of the river flux; the possible effects on two points of the net were also calculated. In the author's opinion, such policy will result in a disposal without a sensible damage in the receptor. (Author)

    Full Text Available In India, due to unprecedented rise in the cost of living, ris-ing prices of commodities, growing expenses on children ed-ucation, huge rate of unemployment, and increasing cost of housing properties compel every Indian family to explore all the possible ways and means to increase the household income. It is also witnessed that after globalization Indian women are able to get more jobs but the work they get is more casual in nature or is the one that men do not prefer to do or is left by them to move to higher or better jobs. Working women refers to those in paid employment. They work as lawyers, nurses, doctors, teachers and secretaries etc. There is no profession today where women are not employed. University of Oxford’s Professor Linda Scott recently coined the term the Double X Economy to describe the global economy of women. The present paper makes an attempt to discuss issues and challenges that are being faced by Indian working women at their respective workstations.

    Full Text Available Various ideas on how the universe appeared and develops, were in Indian tradition related to mythic, religious, or philosophical ideas and contexts, and developed during some 3.000 years - from the time of Vedas, to Puranas. Conserning its appeareance, two main ideas were presented. In one concept it appeared out of itself (auto-generated, and gods were among the first to appear in the cosmic sequences. In the other, it was a kind of divine creation, with hard work (like the dismembering of the primal Purusha, or as emanation of divine dance. Indian tradition had also various critiques of mythic and religious concepts (from the 8th c. BC, to the 6c., who favoured naturalistic and materialistic explanations, and concepts, in their cosmogony and cosmology. One the peculiarities was that indian cosmogony and cosmology includes great time spans, since they used a digit system which was later (in the 13th c. introduced to Europe by Fibonacci (Leonardo of Pisa, 1170-1240.

    Over the last two decades, the fiber optic technology has passed through many analytical stages. Some commercially available fiber optic sensors, though in a small way, are being used for automation in mechanical and industrial environments. They are also used for instrumentation and controls. In the present work, an intensity-modulated intrinsic fiber optic sugar sensor is presented. This type of sensor, with slight modification, can be used for on-line determination of the concentration of sugar content in sugarcane juice in sugar industry. In the present set-up, a plastic fiber made of polymethylmethacrylate is used. A portion of the cladding (1 cm, 2 cm, 3 cm) at the mid-point along the length of the fiber is removed. This portion is immersed in sugar solution of known concentration and refractive index. At one end of the fiber an 850 nm source is used and at the other end a power meter is connected. By varying the concentration of sugar solution, the output power is noted. These studies are made due to the change in refractive index of the fluid. The device was found to be very sensitive which is free from EMI and shock hazards, stable and repeatable and they can be remotely interfaced with a computer to give on-line measurements and thus become useful for application in sugar industries.

    2008-12-01

    Furfural and sugars (as levoglucosan equivalent) are derived from biomass burning and contribute to aerosol composition. This study examined the potential of furfural and levoglucosan to be tracers of biomass burning. Furfural is likely to be oxidized quickly so comparison with levoglucosan may give a sense of the age of the aerosols in forest fire smoke. However, few furfural emissions are available for biomass combustion. Furfural and sugars were determined in coarse aerosols (>2.4?m aerodynamic diameter) and fine aerosols (Furfural and sugars dominated in fine fractions, especially in the UK autumn. Sugars were found at 5.96-18.37 nmol m-3 in fine mode and 1.36-5.75 nmol m-3 in coarse mode aerosols in the UK. Furfural was found at 0.18-0.91 nmol m-3 and 0.05-0.51 nmol m-3 respectively in the same aerosols. Sugars were a dominant contributor to aerosol derived from biomass burning. Sugars and furfural were about 10 and 20 times higher during haze episodes in Malaysia. Laboratory experimental simulation suggested furfural is more rapid destroyed by UV and sunlight than levoglucosan.

    Full Text Available Sugar is an inseparable part of the food we consume. But too much sugar is not ideal for our teeth and waistline. There have been some controversial suggestions that excessive sugar may play an important role in certain degenerative diseases. So artificial sweeteners or artificially sweetened products continue to attract consumers. A sugar substitute (artificial sweetener is a food additive that duplicates the effect of sugar in taste, but usually has less food energy. Besides its benefits, animal studies have convincingly proven that artificial sweeteners cause weight gain, brain tumors, bladder cancer and many other health hazards. Some kind of health related side effects including carcinogenicity are also noted in humans. A large number of studies have been carried out on these substances with conclusions ranging from "safe under all conditions" to "unsafe at any dose". Scientists are divided in their views on the issue of artificial sweetener safety. In scientific as well as in lay publications, supporting studies are often widely referenced while the opposing results are de-emphasized or dismissed. So this review aims to explore the health controversy over perceived benefits of sugar substitutes.

  4. Dietary sugar utilisation by putative oral probiotics.

    2012-09-01

    Probiotic consumption and repeated probiotic intake have shown promising results as adjunct therapies in prevention and alleviation of some chronic disease conditions in the gastrointestinal tract. Recent evidence suggests that probiotics may also be beneficial in preventing oral diseases. An efficient probiotic candidate in the mouth, however, should not impose any risk to oral tissues, such as acid demineralisation of tooth enamel because of sugar fermentation. The aim of the present in vitro study was to evaluate the utilisation of some sugars and sugar alcohols by yogurt starter Lactobacillus delbrueckii subsp. bulgaricus strains and to assess the influence of these carbohydrate sources on cell surface properties. For comparsion, a commercially available probiotic, Lactobacillus rhamnosus GG, was used. The results showed that lactose, glucose and fructose were readily metabolised by all strains tested. However, strain-specific metabolic patterns were observed when other sugars and sugar alcohols were used as sole carbohydrate source in the growth medium. Surface properties of the bacteria such as hydrophobicity and surface-associated proteins appeared to vary with the carbohydrate content of the growth medium. Based on these results it can be concluded that among the L. delbrueckii subsp. bulgaricus strains probiotic candidate strains are available that warrant further studies due to their inability to ferment sugars with pronounced cariogenic properties.

    Sugars are sweet-flavored carbohydrates that provide energy to the body. The adult brain uses about 140 g of glucose per day, amount which can represent up to 50 of the total number of carbohydrates consumed. In our country the sugar in food consumption pattern remains constant, while the consumption of soft drinks has increased in the past four years. The national survey of dietary intake of Spain (ENIDE, 2010-11) estimated that 20% of calories intake comes from carbohydrates called sugars. Sugar consumption has been associated with various pathologies (diabetes, obesity, tooth decay, cardiovascular disease) but these relationships are not consistent enough. Food information through nutritional labeling, including sugars present in food, pretend to protect the consumer health and to guarantee their right to information so they can make their own decisions with criterion. In view of different appraisals and existing studies, and above all, in the absence of a solid scientific evidence that concrete data on which make recommendations, the best nutritional advice for the general population could be a diet varied and balanced with food and nutrients from different sources, combining such a diet with exercise and physical activity. More specifically in terms of moderate consumption of sugar in the previous context of varied and balanced diet is perfectly compatible. PMID:23834090

  6. KRAFT MILL BIOREFINERY TO PRODUCE ACETIC ACID AND ETHANOL: TECHNICAL ECONOMIC ANALYSIS

    Directory of Open Access Journals (Sweden)

    Haibo Mao

    2010-05-01

    Full Text Available The “near neutral hemicellulose extraction process” involves extraction of hemicellulose using green liquor prior to kraft pulping. Ancillary unit operations include hydrolysis of the extracted carbohydrates using sulfuric acid, removal of extracted lignin, liquid-liquid extraction of acetic acid, liming followed by separation of gypsum, fermentation of C5 and C6 sugars, and upgrading the acetic acid and ethanol products by distillation. The process described here is a variant of the “near neutral hemicellulose extraction process” that uses the minimal amount of green liquor to maximize sugar production while still maintaining the strength quality of the final kraft pulp. Production rates vary between 2.4 to 6.6 million gallons per year of acetic acid and 1.0 and 5.6 million gallons per year of ethanol, depending upon the pulp production rate. The discounted cash flow rate of return for the process is a strong function of plant size, and the capital investment depends on the complexity of the process. For a 1,000 ton per day pulp mill, the production cost for ethanol was estimated to vary between $1.63 and $2.07/gallon, and for acetic acid between $1.98 and $2.75 per gallon depending upon the capital equipment requirements for the new process. To make the process economically attractive, for smaller mill sizes the processing must be simplified to facilitate reductions in capital cost.

    The Iowa Corn Promotion Board is the principal contracting entity for this grant funded by the US Department of Agriculture and managed by the US Department of Energy. The Iowa Corn Promotion Board subcontracted with New Jersey Institute of Technology, KiwiChem, Pacific Northwest National Lab and Idaho National Lab to conduct research for this project. KiwiChem conducted the economic engineering assessment of a dry-mill ethanol plant. New Jersey Institute of Technology conducted work on incorporating the organic acids into polymers. Pacific Northwest National Lab conducted work in hydrolysis of hemicellulose, fermentation and chemical catalysis of sugars to value-added chemicals. Idaho National Lab engineered an organism to ferment a specific organic acid. Dyadic, an enzme company, was a collaborator which provided in-kind support for the project. The Iowa Corn Promotion Board collaborated with the Ohio Corn Marketing Board and the Minnesota Corn Merchandising Council in providing cost share for the project. The purpose of this diverse collaboration was to integrate the hydrolysis, the conversion and the polymer applications into one project and increase the likelihood of success. This project had two primary goals: (1) to hydrolyze the hemicellulose fraction of the distillers grain (DG) coproduct coming from the dry-mill ethanol plants and (2) convert the sugars derived from the hemicellulose into value-added co-products via fermentation and chemical catalysis.

To protect sugar beet effectively, two variants of herbicides application are proposed. The first one - a combined, one stipulating soil action herbicides application before planting or before sugar beet seedlings emergence and on seedlings - to carry out two treatment by post-emergence preparations. The second variant, a split post- -emergence herbicide application (two-three times spraying on growing weeds at small application rates. In the next 5-6 years, a combined method will be of a primary importance in the conditions of the Republic.

    Ziziphus is an important genus within the family Rhamnaceae. This genus includes several important fruit tree species that are widely planted in China and India, such as the Chinese jujube (Ziziphus jujuba Mill.), the wild jujube (Z. acidojujuba), and the Indian jujube (Z. mauritiana). However, information about their domestication based on the chlorotype diversity of Chinese jujube population is lacking. In this study, chloroplast microsatellite (cpSSR) markers were developed and used to investigate the genetic relationships between and domestication of jujube cultivars and wild jujube populations. Primer sets flanking each of the 46 cpSSR loci in non-coding regions of the chloroplast genome sequence of Z. jujuba Mill. cv. 'Junzao' were designed. In total, 10 markers showed polymorphisms from 15 samples (9 jujube cultivars and 6 wild jujube individuals), of which 8 loci were due to variations in the number of mononucleotide (A/T) repeats and 2 were due to indels. Six cpSSR markers were used in further analyses of 81 additional samples (63 jujube cultivars, 17 wild jujube samples, and 1 Indian jujube). Using these cpSSR markers, the number of alleles per locus ranged from two to four. In general, the Shannon Index (I) for each cpSSR ranged from 0.159 to 0.1747, and the diversity indices (h) and uh were 0.061 to 0.435 and 0.062 to 0.439, respectively. Seven chlorotypes were found; the Indian jujube showed distinct chlorotypes, and both the Chinese and wild jujube had four chlorotypes and shared two chlorotypes. A dominant chlorotype (G) accounted for 53 of 72 jujube cultivars and 13 of 23 wild jujube individuals. All chlorotypes were highly localized along the Yellow River, from the mid- to the lower reaches, suggesting a wide origin of jujube. These cpSSR markers can be applied to population and evolution studies of Chinese jujube and wild jujube. PMID:26406601

    Double grinding of mill streams without intermediate sieving, i.e. the eight-roller milling system provides opportunities for significant reduction of capital cost compared to conventional wheat flour milling system. In this study the effects of using the eight-roller mill in the purifier-less mill flow were investigated. Middlings from the break system of commercial flour mill, which would be sent to the purification system, were intercepted and employed in the experiments. Milling results obtained with double grinding of middlings were compared with the results obtained by conventional system with intermediate sifting before regrinding of stock. At the same roll gap setting and under the same sieving conditions, the eight-roller system produced less flour compared to the conventional system. Results showed that the most efficient way to increase flour yield in the eight-roller milling system is to increase the upper size limit of flour by increasing the sieve aperture. This is not followed by the deterioration of flour quality as determined by ash content. Increase of the upper size limit of flour particles is followed by the decrease of the flour ash content suggesting that it is possible to implement the eight-roller mills in the purifier-less mill flow.

    Full Text Available Application of Fenton's reaction for a proper hydrolysis step is an essential and important step in obtaining a higher level of readily biodegradable sugars from palm oil mill effluent (POME for improving the alcohol production by using immobilized Clostridium acetobutylicum. The objective of this research was, therefore, to investigate the optimum condition of Fenton's reaction in terms of COD: H2O2 ratios (w/w and H2O2: Fe2+ ratios (molar ratio used to oxidize carbohydrate and high molecular organic compounds into simple sugars, which are further fermented into alcohol. The experiments were carried out at H2O2: Fe2+ ratios (molar ratios of 5, 10, 20, 30 and 40 and the COD: H2O2 ratios (w/w of 50, 70, 100 and 130 (initial COD about 50,000 mg/L. The total sugar concentrations and organic compounds biodegradability (BOD5/COD ratios were also used for investigating suitable conditions for Fenton's reaction. The concentration of Fenton's reagent at H2O2:Fe2+ and COD:H2O2 ratio of 20 and 130 was identified as the optimum operating condition for the highest simple sugars of about 0.865% and BOD5/COD ratios of 0.539. The alcohol productions were carried out in the continuous stirred tank reactors (CSTR under an anaerobic continuous immobilization system. At a hydraulic retention time of 12 hours and POME pH of 4.8, the maximum total ABE concentration of 495 mg/L and the ABE yield of 0.236 grams of ABE produced/gram of reducing sugars were achieved at the mixed polyvinyl alcohol (PVA and palm oil ash (POA ratio of 10 : 3.

  14. Greenhouse gasses emissions and energy balances of a non-vertically integrated sugar and ethanol supply chain: A case study in Argentina

    International Nuclear Information System (INIS)

    In order to address society's concerns regarding the sustainability of sugar and ethanol production and use, this paper calculates the energy and greenhouse gasses (GHG) emissions' balances of a non-vertically integrated sugarcane industry in Tucumán-Argentina. The essential operations involved in the sugar/ethanol production cycle were taken into account. Results show that this industry generated an energy balance of 3.4:1. GHG emissions during sugarcane production were 1824 and 2231 kg CO2eq. ha−1 year−1 for low and middle to high farms' technological levels, respectively. The mill process emitted 1187 kg CO2eq. ha−1 year−1. The main factors influencing these balances were gas-oil and nitrogen fertilizers used in the agricultural stage, natural gas consumed by the sugar mill, and sugarcane burning (only for GHG balance). The impact of ethanol use in reducing GHG emissions under the current production scheme (6.8 Mg ha−1 of sugar + 380.9 kg ha−1 of ethanol), in final blends of 95% gasoline and 5% ethanol in vehicles, is negligible. A sensitivity analysis indicates that switching to 100% bagasse used as fuel in mill's boilers, ethanol being produced directly from sugarcane juice, and a final blend of 90% gasoline and 10% ethanol, an amount of 1746 kg CO2eq. ha−1 year−1 of GHG emissions could be avoided. - Highlights: ► Energy and GHG emissions' balances for the non-integrated sugar/ethanol industry in Tucumán-Argentina. ► The energy balance was positive, while there were important GHG emissions. ► Factors influencing both balances were gas-oil, N fertilizers, burning and natural gas. ► Ethanol use for reducing GHG emissions in the current production scheme is negligible. ► Results are promising, as the main factors influencing both balances are identified

    2013-01-01

    Pectin from sugar beet is derived from the sugar beet pulp residue which results when sugar beets are processed for sucrose extraction. The sugar beet pectin has poor gelationability by the classic divalentcation molecular mechanism because of a relatively high acetylation degree and short polygalacturonate backbone chain length. However, due to the feruloyl-substitutions on the side chains, the sugar beet pectic polysaccharides can be cross-linked via enzyme catalyzed oxidation. The enzyme kine...

    By regarding gravity as the convolution of left and right Yang-Mills theories together with a spectator scalar field in the biadjoint representation, we derive in linearized approximation, the gravitational symmetries of general covariance, p -form gauge invariance, local Lorentz invariance, and local supersymmetry from the flat space Yang-Mills symmetries of local gauge invariance and global super-Poincaré symmetry. As a concrete example, we focus on the new minimal (12 +12 ) off shell version of simple four-dimensional supergravity obtained by tensoring the off shell Yang-Mills multiplets (4 +4 , NL=1 ) and (3 +0 , NR=0 ).

    Fault diagnosis of industrial equipments is more and more important for improving the quality of products and avoiding a waste of money and resources, especially for expensive precision machines, like the milling machine used in Berg Propulsion. If the milling process is continued when the cutting tool is worn out, one may have a failure product. This will cost the company a lot of money. And what’s more, with the time going on, the worn out tool may cause the damage to the milling machine. S...

  9. Coal Moisture Estimation in Power Plant Mills

    Knowledge of moisture content in raw coal feed to a power plant coal mill is of importance for efficient operation of the mill. The moisture is commonly measured approximately once a day using offline chemical analysis methods; however, it would be advantageous for the dynamic operation of the plant if an on-line estimate were available. In this paper we such propose an on-line estimator (an extended Kalman filter) that uses only existing measurements. The scheme is tested on actual coal mill da...

    Sugar beet press pulp accumulates as a by-product in sugar factories. Rising energy prices and the opening of the European Union sugar market has put pressure on the manufactures to find alternatives for energy supply. The aim of this project was to develop a technology in the treatment of sugar beet press pulp that would lead to savings in energy consumption, decline of treatment costs and to a more competitive production. These goals were met by the anaerobic digestion of SBP for biogas production. In the first implementation step at a Hungarian sugar factory half of the SBP (800 t/d, 22%TS) was converted into biogas, which could substitute about 40% of the natural gas required for the thermal energy supply within a sugar campaign. Lab-scale experiments were performed to gain basic information about the suitability of sugar beet press pulp as substrate for anaerobic bacteria and the stability of the anaerobic process. Pilot-scale experiments focused on process optimization and procedures for a quick start up and operational control. The results of the experiments led to the implementation of a fullscale biogas plant, which has been put in operation during the sugar campaign 2007. The maximum input load of press pulp was about 925 t/d (9.3 kgCSB/m{sup 3}.d), with a biogas production of 125,000 Nm{sup 3}/d.

    The sugar industry goes through an important moment: invest and develop to supply future demand, mainly by fuel alcohol (around 70% of new vehicles sales are from flex fuel models - and the majority of these vehicles are supplied by alcohol). Due to this foreseeable increase of alcohol demand, sugar industry has already announced 41 new projects, which will contribute with the milling of 70 million tons of sugar cane by the conclusion of these plants. In this phase of expansion, the alcohol market must be pressured for the demand, managing the supplying of the domestic and external markets. With this scenario and the possibility of sector growth which has an important role in Brazil development, this work evaluates the economic impacts of the new plants implementation investments.

    Full Text Available During 1998-2002, the application of different forms and doses of nitrogen on quantitative (polarised sugar productionand qualitative parameters (digestion, molasses forming components - potassium, sodium and ?-amino nitrogen content of sugar beet in vulnerable zones (Nitrate directive was studied. Calculated input of nitrogen ranged from 12 kg up to 240 kg N.ha-1. By increasing input of N from FYM application into the soil causes an increases of ?- amino nitrogen content in root, which in consequence causes a decreases the sugar content (negative correlation r= -0.8659+. The application of straw instead FYM of analogues treatments caused significant decrease (straw versus FYM and highly significant decrease (straw plus N fertilizers versus FYM plus N fertilizers of ?-amino nitrogen content in sugar beet root living the productive parameters unchanged. The content of ?-amino nitrogen in root of sugar beet indicate an environmentally friendly management practices with causal relation to water protection from nitrate.
