    2010-04-01

    Full Text Available A fracture mechanics-based method is presented for determining critical crack size and residual life of upper sugar-mill shafts having semi-elliptical and circumferential cracks. Due to the multiaxial stress field, an equivalent strain energy release rate stress intensity solution is used in Paris’ law to predict crack growth. Ultrasonic inspection intervals for the shaft were established. The crack zone evaluated was located in the shoulder of the bearing nearest to the square box coupling where about 25% of service failures in these types of shaft are observed.

    2013-12-01

    The U.S. Environmental Protection Agency (EPA) launched the RE-Powering America's Land initiative to encourage development of renewable energy on potentially contaminated land and mine sites. EPA collaborated with the U.S. Department of Energy's (DOE's) National Renewable Energy Laboratory (NREL) and the Mille Lacs Band of Chippewa Indians to evaluate the wind resource and examine the feasibility of a wind project at a contaminated site located on the Mille Lacs Indian Reservation in Minnesota. The wind monitoring effort involved the installation of a 60-m met tower and the collection of 18 months of wind data at multiple heights above the ground. This report focuses on the wind resource assessment, the estimated energy production of wind turbines, and an assessment of the economic feasibility of a potential wind project sited this site.

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

    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

  10. Feasibility Assessment of Converting Sugar Mills to Bioenergy Production in Africa

    Manoel Regis Lima Verde Leal

    2016-09-01

    Full Text Available World sugar production has consistently overrun demand in the past five years. Moreover, in 2017 the European Sugar Regime will expire, ending the quota system and preferential sugar prices, largely affecting small producers, particularly in Africa. Diversification emerges as an option for sugar-oriented mills. Two evident alternatives are ethanol and electricity production that allow better use of molasses and cane fibers, respectively. Molasses is the cheapest feedstock for ethanol production, while the cane fibers—in the form of bagasse—are readily available at the mill. The transition from sugar to sugar, ethanol and electricity may require substantial investment capital, yet our results show that significant progress can start at relatively small cost. In this work, we use simulations to explore the impact of ethanol and electricity production in an existing sugar mill in Mozambique. In spite of the large amounts of energy obtained from ambitious scenarios, such as Ethanol-2 and Ethanol/EE, molasses-based ethanol (Ethanol-1 scenario seems more attractive in economical and infrastructural terms. High opportunity costs for molasses, low oil prices and enabling institutional conditions, such as mandatory blending mandates, to promote bioenergy remain a challenge.

    Mangesh J. Goundalkar

    2014-03-01

    Full Text Available To further elucidate the advantageous effects of hot-water extraction (HWE on delignification, milled wood lignin (MWL was isolated from sugar maple (SM and from hot-water extracted sugar maple (ESM. Ball-milled wood was analyzed for particle size distribution (PSD before and after dioxane:water (DW extraction. The MWL samples were analyzed by analytical and spectral methods. The results indicated that the MWL isolated from SM and ESM was mainly released from the middle lamella (ML and the secondary wall (SW, respectively. The cleavage of dibenzodioxocin (DB and spirodienone (SD lignin substructures during HWE is suggested. The removal of lignin during acetone:water (AW extraction of hot-water extracted wood indicates that including an additional operation in a hardwood HWE-based biorefinery would be beneficial for processing of wood.

    Dominguez-Manjarrez Candi Ashanti

    2014-10-01

    Full Text Available This research paper aims to recommend control measures directed towards preventing and minimizing pollution, looking forward to the improvement of the environmental management on the sugar industry in Mexico. This issue has been put on hold due to the necessity to address the economic, social and technological issues affecting it over time. In order to better understand the productive process and the actual problem that the industry is facing, while proposing effective and possible actions for improvement, a sugar mill type was selected as a case of study. A comprehensive assessment of the production process for the standard sugar was made, considering the activities in the field and at the mill. The proposed measures in the sugar mill allowed savings in consumption of ground water average 3,620 cubic meters per day, during the period of study, reduction in solid waste generated average 325 kilograms per day by implementing a waste separation program, and reducing atmospheric emissions of particles acting as fuel for a boiler operated with bagasse. The prevention, minimization and pollution control measures proposed can be applied to other mills in the country with the appropriate adaptations.

  14. Operations improvement of the recycling water-cooling systems of sugar mills

    Shcherbakov Vladimir Ivanovich

    Full Text Available Water management in sugar factories doesn’t have analogues in its complexity among food industry enterprises. Water intensity of sugar production is very high. Circulation water, condensed water, pulp press water and others are used in technological processes. Water plays the main role in physical, chemical, thermotechnical processes of beet processing and sugar production. As a consequence of accession of Russia to the WTO the technical requirements for production processes are changing. The enforcements of ecological services to balance scheme of water consumption and water disposal increased. The reduction of fresh water expenditure is one of the main tasks in economy of sugar industry. The substantial role in fresh water expenditure is played by efficiency of cooling and aeration processes of conditionally clean waters of the 1st category. The article contains an observation of the technologies of the available solutions and recommendations for improving and upgrading the existing recycling water-cooling systems of sugar mills. The authors present the block diagram of the water sector of a sugar mill and a method of calculating the optimal constructive and technological parameters of cooling devices. Water cooling towers enhanced design and upgrades are offered.

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

    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)

    Kato, Taku; Ohara, Satoshi; Fukushima, Yasuhiro; Sugimoto, Akira; Masuda, Takayuki; Yasuhara, Takaomi; Yamagishi, Hiromi

    2016-07-01

    Advances in glucose/fructose-selective ethanol production have successfully enhanced raw sugar extraction from sugarcane juice by converting inhibitory substances (i.e., glucose/fructose) into ethanol, which is removed by subsequent operations in cane sugar mills. However, the commercial implementation of this breakthrough process in existing cane sugar mills requires a yeast strain that (i) can be used in food production processes, (ii) exhibits stable saccharometabolic selectivity, and (iii) can be easily separated from the saccharide solution. In this study, we developed a suitable saccharometabolism-selective and flocculent strain, Saccharomyces cerevisiae GYK-10. We obtained a suitable yeast strain for selective fermentation in cane sugar mills using a yeast mating system. First, we crossed a haploid strain defective in sucrose utilization with a flocculent haploid strain. Next, we performed tetrad dissection of the resultant hybrid diploid strain and selected GYK-10 from various segregants by investigating the sucrose assimilation and flocculation capacity phenotypes. Ten consecutive fermentation tests of the GYK-10 strain using a bench-scale fermentor confirmed its suitability for the implementation of practical selective fermentation in a commercial sugar mill. The strain exhibited complete saccharometabolic selectivity and sustained flocculation, where it maintained a high ethanol yield and conversion rate throughout the test. PMID:26811219

    2014-02-03

    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

  19. 甘蔗糖厂入榨甘蔗蔗糖分采样测定方法%The Sampling Method for Measuring Sugar Content of Milling Sugar Cane in Sugar Factory

    张彩霞

    2015-01-01

    In sugar factory, it is generally known that the traditional sampling methods of milling sugar cane have a disadvantage of poor representation due to the arbitrary and artificial factors, the method of calculating sugar content through continuously sampling of mixed juice and bagasse has long lag-time and cannot reflect sugar loss in pressing process, so there still exists some deviations in evaluating the quality of sugar cane. Analyzing sugar content of milling sugarcane can be more accurate and timely through continuously collecting defibrated cane from cane shredder, which provides a basis for sugarcane unhindered management and process management. This article introduces mainly the applications of technique in sugar industry during the milling campaign.%糖厂入榨甘蔗用传统的采样方法由于人为随意性导致样本代表性差,而班报用混合汁和蔗渣连续采样计算出甘蔗蔗糖分的方法存在滞后时间长和未反映压榨过程糖分损失的缺点,对评价甘蔗质量存在一定的偏差。连续采集撕解机蔗丝样的方法可以更及时准确分析入榨甘蔗蔗糖分,为农务甘蔗管理、制糖工艺管理提供依据。本文介绍这种方法在糖厂榨季生产中的应用情况。

    2009-01-01

    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.

  1. Effect of amendments on chemical immobilization of heavy metals in sugar mill contaminated soils

    Mohammad Jamal Khan, Muhammad Tahir Azeem and Sajida Perveen1

    2012-05-01

    Full Text Available A bulk soil sample collected from the vicinity of PSM (Premier Sugar Mill Mardan was amended with diammonium phosphate (DAP, triple super phosphate (TSP, Farm Yard Manure (FYM and poultry manure (PM in 1.5 kg soil in a 2 L plastic pot. Both DAP and TSP were added at 230 mg kg 1 (460 kg ha 1 soil whereas the organic amendments (FYM and PM were added at the rate of 10% by weight of soil. The air dried samples in pots were brought to field moisture content (0.33 bar water content by the addition of either HIE (Hayatabad Industrial Estate or PSM in two separate sets of experiments. The experimental pots were arranged in randomized complete design with three replicates under laboratory conditions during March to May (Temperature varying between 25 to 30 °C. Treated and control pots were incubated for 90 days al 0.33 bar ca 25% moisture and the moisture deficit during the incubation time was adjusted by adding PSM and HIE effluents in their respective set of experimental pots. 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

    2015-01-01

    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.

    1998-12-31

    Considering the new legal frame on cogeneration in Mexico, the possibility of heat and electricity supply required by the sugar mills to be made by an independent cogenerator of the sugar mill, operating with the sugar cane bagasse and agricultural sugar cane wastes, has been evaluated. Such modern cogenerator would be characterized, besides operating in an independent way of the sugar mill, by the use of high efficiency equipment in its process of heat and electricity generation. In this sense the Comision Nacional para el Ahorro de Energia (CONAE) through its Coordination Program and the Instituto de Investigaciones Electricas (IIE) carried out a joint project to determine the technical and economical viability that the sugar industry maintains the present sugar production without the need of burning fuel oil, installing adjacent to every sugar mill, a modern cogeneration system, operated by independent producers, that using sugar cane bagasse and agricultural sugar cane wastes, allows the supply of all the steam and electricity required by the sugar mill, and additionally can add firm capacity and the supply of electric power to the national grid, during the grinding season as well as out of grinding season.

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

    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.

    Liu, Qiyu; Li, Wenzhi; Ma, Qiaozhi; An, Shengxin; Li, Minghao; Jameel, Hasan; Chang, Hou-Min

    2016-07-01

    A two-stage process was evaluated to increase sugar recovery. Firstly, corn stover was treated with dilute hydrochloric acid to recover the xylose, and then the residue was subjected to a wet-milling pretreatment. Dilute hydrochloric acid showed a high xylose recovery during the first stage. The optimal condition was 120°C and 40min for 0.7wt% dilute hydrochloric acid pretreatment followed by wet-milling pretreatment for 15min. The xylose and glucose yield were 81.0% and 64.0%, respectively, with a cellulase dosage at 3FPU/g of substrate. This two-stage process was effective on account of the removal of hemicelluloses in the first stage and the delamination of cell wall in the second stage, increasing the possibility of adsorption of cellulose to enzymes, and resulting in a high sugar recovery with a very low enzyme loading.

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

    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

    甘蔗制糖业是广西支柱产业,并且是高能耗行业。以某日榨7000吨的甘蔗糖厂为例,对其锅炉建立分析模型并进行了能量分析,结果效率比热效率低一半左右。分析模型揭示了糖厂锅炉的能耗来源,为糖厂锅炉的节能降耗优化改造提供了理论支持。%Cane sugar manufacturing industry was a main industry in Guangxi, and was a highly energy-consuming trade. Taking a sugar mill of daily output of 7 000 t and making an exergy analysis of its boiler, the results showed that the exergy efficiency was lower about a half than that of the thermal efficiency. The exergy analysis model showed the origin of the energy loss, and could provide theoretical support for energy saving and optimal modification of the boiler in cane sugar mills.

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

    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

    Gottesfeld, Perry; Nicas, Mark; Kephart, John W; Balakrishnan, Kalpana; Rinehart, Richard

    2008-01-01

    Respirable crystalline silica dust generated during stone crushing operations has been linked to chronic lung disease and increased risk of tuberculosis. In India, most stone crushing mills operate without any dust control or containment systems. This investigation in the Khurda District of Orissa demonstrated a reduction in respirable particulate mass following the application of a fine mist of water. Average respirable quartz and cristobalite levels declined 82% and 69%, respectively, after water spray controls were installed. This finding suggests that relatively inexpensive modifications that are available in the local market can be effective at reducing silica exposures. Although average exposure levels, particularly during the dry season, may exceed the Permissible Exposure Limit for silica, the overall reductions observed were substantial. Widespread adoption of this simple control technology by stone crushers in India could have a positive public health impact. PMID:18507285

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

    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)

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

    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)

    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

  20. The Value of the Freshwater Snail Dip Scoop Sampling Method in Macroinvertebrates Bioassessment of Sugar Mill Wastewater Pollution in Mbandjock, Cameroon

    2008-03-01

    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.

    Globally the increasing prevalence of diabetes mellitus (DM) is major public health concern. The Indian Diabetes Risk Score (IDRS) was developed by Madras Diabetes Research Foundation (MDRF) as a simple tool to help detect undiagnosed type 2 DM (T2DM) in the community. We conducted a study among 911 adults of Jabalpur District to validate the IDRS score against increased fasting blood sugar levels in diagnosing T2DM. T2DM was confirmed either by history of previously known disease or fasting plasma glucose ≥126 mg/dl on two occasions. Sensitivity, specificity, positive predictive value, negative predictive value, Youden index (sensitivity + specificity -1), likelihood ratio for positive test, and likelihood ratio for negative test were calculated for IDRS cut-offs of ≥20, ≥40, ≥60, and ≥80 against the presence of T2DM (either known diabetic or fasting plasma glucose >126 mg/dl on two occasions). The overall prevalence of T2DM was 9.99% (95% confidence interval, 8.04-11.94%). In the Receiver operating characteristic analysis, IDRS had an area under the curve of 0.736 (P indicate that IDRS has excellent predictive value for detecting undiagnosed diabetes in the community and IDRS is also a much stronger risk indicator than examining individual risk factors like age, family history, obesity, or physical activity.

  14. The cogeneration potential of the sugar industry in Vietnam

    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)

  15. Rising critical emission of air pollutants from renewable biomass based cogeneration from the sugar industry in India

    Sahu, S. K.; Ohara, T.; Beig, G.; Kurokawa, J.; Nagashima, T.

    2015-09-01

    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.

  16. Impact of sugar industry fly ash emissions on environment

    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)

    Outlaw, Joe L.; Ribera, Luis A.; Richardson, James W.; da Silva, Jorge; Bryant, Henry L.; Klose, Steven L.

    2007-01-01

    The feasibility of integrating ethanol production into an existing sugar mill was analyzed by a stochastic spreadsheet model. As the price of corn continues to rise, ethanol producers will eventually need to look at other feedstock alternatives. Sugarcane has been proven to work well in the production of ethanol in Brazil. The results indicated existing U.S. sugar mills could economically switch to ethanol production. As imports into the United States threaten to undermine the U.S. sugar prog...

  3. Sugar industry dilemma in NWFP

    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

  4. Monitoreo de un sistema de secado de bagazo acoplado a una caldera en un ingenio de México Monitoring of a bagasse drying system attached to a boiler in a sugar mill in Mexico

    Federico J. Franck Colombres

    Full Text Available Se evaluó el desempeño de un secador de bagazo diseñado por la Estación Experimental Agroindustrial Obispo Colombres, acoplado a una caldera bagacera convencional en un ingenio de México (caldera Nº 5. Para ello, se realizaron ensayos de mediciones y balances de materia y energía, para la caldera operando con el secador y sin él en funcionamiento. La caldera Nº 5, de una producción nominal de 60 t/h de vapor y una presión máxima de trabajo de 29 bar, cuando fue alimentada únicamente con bagazo húmedo pudo generar como máximo 33 t/h de vapor a 19 bar y 269ºC, con un rendimiento energético de 60,4% y un índice de generación de 1,6 kg de vapor/ kg de bagazo. Con la adición del secador, se logró secar 28,6 toneladas de bagazo de 50,2% a 30,4% de humedad. Aproximadamente un 72% de este bagazo presecado se mezcló con bagazo húmedo y se utilizó para alimentar la caldera, produciéndose así 58,4 t/h de vapor; es decir, 77% más de vapor que sin secador. El rendimiento energético del sistema caldera-secador fue de 73,6%, un 21,8% superior al de la caldera sin secador, mientras que el índice de generación fue de 2,0 kg de vapor/ kg de bagazo, 25% mayor que el de la caldera original. Este aumento en la producción de vapor permitió sacar de servicio a la caldera Nº 6, que producía aproximadamente 20 t/h de vapor, con un rendimiento similar al de la caldera Nº 5 sin secador. Estas mejoras dieron como resultado, un ahorro de energía de 45,4 MJ/h, aproximadamente un 18% respecto a la energía consumida por ambas calderas (Nº 5 y Nº 6 cuando no funcionaba el secador. Este ahorro equivale a 1103 l/h de "fuel oil", es decir, alrededor de 1,5 millones de dólares por zafra.A bagasse dryer designed by Estación Experimental Agroindustrial Obispo Colombres was attached to a conventional bagasse boiler (Boiler No. 5 in a sugar mill in Mexico for evaluation.

  6. Rising critical emission of air pollutants from renewable biomass based cogeneration from the sugar industry in India

    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. (letter)

  14. The Truth about Sugar.

    Yeung, C Albert; Goodfellow, Ashley; Flanagan, Louise

    2015-01-01

    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

    Full Text Available This paper presents a study in the port sector specialized in handling of bagged sugar. Sugar has always been exported in bags of 50 kg, placed directly in the holds of ships for general cargo. It appears that this form of transport has become obsolete now, the market for the direct form of transport of sugar packed in containers. Companies involved in this type of port handling need understand the reasons that are influencing this new mode of transportation as a way to fit and remain active and competitive in the industry.

  5. Sugar and Other Sweeteners

    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

    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.

    Barbaro, Elena; Kirchgeorg, Torben; Zangrando, Roberta; Vecchiato, Marco; Piazza, Rossano; Barbante, Carlo; Gambaro, Andrea

    2015-10-01

    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.

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

    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

    Sugar market is one of the most protected markets for agricultural products world wide. In almost every sugar producing country the sugar market is regulated in some way. With an increasing liberalization of agricultural trade in the "Millennium Round" of the WTO trade negotiations, the question of international competitiveness is of increasing importance. Based on empirical studies, in this article the competitiveness of sugar production in the most important sugar producing countries is ana...

  19. Indian Summer

    Galindo, E. [Sho-Ban High School, Fort Hall, ID (United States)

    1997-08-01

    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.

  20. Intestinal sugar transport

    Laurie A Drozdowski; Alan BR Thomson

    2006-01-01

    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 sucraseisomaltase 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.

  3. Pitt Mill Demonstration

    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.

  4. Evaluation of soil contents in sugar cane loading using activation analysis

    When sugar cane is cut and taken to the sugar and alcohol mills, a significant quantity of soil is loaded with the stalks. This content has been reduced to 1% due to improvement in harvesting methods. Elements present in soil but not in sugar cane have been studied to act as tracers in the determination of unwanted minerals.

    2005-01-01

    The various assessments of the effects of a liberalization of world sugar markets are largely inconsistent. One cause seems to be the modeling of the EU supply response. We investigate three possible linkages between production quota sugar and the out-of-quota or "C" sugar supply: i/ the existence of fixed costs covered by the in-quota sugar; ii /the "overshooting" behavior as prevention against poor yields; iii/ the production of C sugar as "reference building" in view of expected reforms.

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

    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

  20. Starches, Sugars and Obesity

    Erik E. J. G. Aller

    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.

    2011-01-01

    Objective: To examine acid production of caries-associated strains of oral microorganisms and salivary microorganisms from sugar and sugar substitutes. Methods:Standard and clinical strains of Streptococcus mutans (S. mutans), Lactobacillus casei (L. casei) and Candida albicans were incubated in peptone-yeast-extract media containing 1% test sugar (sucrose, glucose, fructose) or sugar substitutes (xylitol, sorbitol, trehalulose and palatinose) at 37 ℃in 5% CO2 for 24-48 h. The pH of each culture was measured and microbial growth was determined as optical density at 660 nm. Paraffin-stimulated saliva collected from high caries-risk persons were added to media containing 10%test sugar or sugar substitutes. The pH of medium was measured at each time interval from 0-90 minutes. Results:All types of sugar and trehalulose could be fermented by all test microorganisms in pH lower than 5.5 except sucrose by standard strain of L. casei. All sugar and sugar substitutes supported growth of all organisms except xylitol for S. mutans. In the fermentation assay by salivary microorganisms, all sugar could be utilized and produced pH< 5.5 within 10 minutes of incubation and the pH drop was prolonged to until 90 minutes. Conversely, xylitol and palatinose were not fermented by microorganisms in saliva. Conclusions:All test microorganisms could ferment sucrose, glucose, fructose and trehalulose to pH lower than 5.5. Sugar alcohols and palatinose were not utilized well by organisms and may be used as sugar substitutes to reduce dental caries incidence. However, further studies particularly clinical investigations are required to evaluate the cariogenicity of these sugar substitutes.

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

    Zedillo Ponce de Leon, Luis [Grupo de paises Latinoamericanos y del Caribe exportadores de azucar (Mexico)

    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.

  4. Ball milling pretreatment of oil palm biomass for enhancing enzymatic hydrolysis.

    Zakaria, Mohd Rafein; Fujimoto, Shinji; Hirata, Satoshi; Hassan, Mohd Ali

    2014-08-01

    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

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

    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

  6. Free Sugar Profile in Cycads

    Thomas Edward Marler

    2014-10-01

    Full Text Available The sugars fructose, glucose, maltose, and sucrose were quantified in seven tissues of Zamia muricata Willd. to determine their distribution throughout various organs of a model cycad species, and in lateral structural roots of 18 cycad species to determine the variation in sugar concentration and composition among species representing every cycad genus. Taproot and lateral structural roots contained more sugars than leaf, stem, female strobilus, or coralloid roots. For example, taproot sugar concentration was 6.4-fold greater than stem sugar concentration. The dominant root sugars were glucose and fructose, and the only detected stem sugar was sucrose. Sucrose also dominated the sugar profile for leaflet and coralloid root tissue, and fructose was the dominant sugar in female strobilus tissue. Maltose was a minor constituent of taproot, leaflet, and female strobilus tissue, but absent in other tissues. The concentration of total free sugars and each of the four sugars did not differ among genera or families. Stoichiometric relationships among the sugars, such as the quotient hexoses/disaccharides, differed among organs and families. Although anecdotal reports on cycad starch have been abundant due to its historical use as human food and the voluminous medical research invested into cycad neurotoxins, this is the first report on the sugar component of the non-structural carbohydrate profile of cycads. Fructose, glucose, and sucrose are abundant in cycad tissues, with their relative abundance highly contrasting among organs. Their importance as forms of carbon storage, messengers of information, or regulators of cycad metabolism have not been determined to date.

  8. Assessment of heavy metals introduced into food through milling process: health implications

    The present study was conducted to characterised and assesss heavy metal contamination in food through milling process and their health implications. Grinding plate made from Ghana, India and Nigeria purchased from the Ghanaian open market were used for this work. Maize from the same farm was milled into flour using the three grinding plate inserted into three different corn milling machines operating on commercial bases. Th first grinding was done immediately after the insertion of the newly sharpened plates into the machines. The plates were left for continuous daily usage. Subsequent milling of the maize was done after intervals of one month. The grinding plates and maize flour was analysed using Atomic absorption spectrophometer (AAS). The resultes recorded indicated that the heavy metals content o the Ghanaian, Indian and Nigerian made plates had the e similar metal contents but varied in terms of the individual metal concentrations. Flour from the Ghanaian made plates had the highest level of contaminants with the least from that of the Indian made plates. Generally, the highest levels of contamination were observed in the fist milling for the three plates as compared to the three subsequent milling at monthly interval. The contamination levels showed a decreasing trend from the first month (first milling ) to the fourth month (fourth milling). Cu, Cr and Ni showed concentrations above the permissible limit set by FAO/WHO in milled maize using Ghanaian made plate. Copper (Cu) recorded a concentration value between 15.04 mg/kg to 10.21mg.kg, 11.25 mg/kg to 9.13mg/kg and 10.36mg/kg and 9.68mg/kg using the Ghanaian-, Indian and Nigerian made plate respectively. Chromium (Cr) recorded a concentration between 1.51 mg/kg to 0.96 mg/kg, 1.03mg/kg to 0.91 mg/kg and 0.98mg/kg to 0.80 mg/kg using Ghanaian-, Indian and Nigerian made plates respectively. Nickel (Ni) recorded a concentration value between 23.23 mg/kg to 10.43 mg/kg, 11.46mg/kg to 10.43 mg/kg and 12.55 mg

  16. Simultaneous assay of neutral sugars and amino sugars by an automatic sugar analyzer: applications to glycoproteins.

    Kellich, G; Ziegler, D

    1975-04-01

    The simultaneous assay of neutral sugars and amino sugars commonly found in glycoproteins is described. The automatic sugar analyzer used for the determination is based on the ion-exchange chromatography of sugar-borate complexes on a strong anion-exchange resin. The sugars are identified with the orcinol/sulfuric acid reagent. While less than 40 nmol of mannose, fucose, galactose, glucose, xylose, or arabinose is sufficient for analysis at least 200 nmol mannosamine, glucosamine, or galactosamine is required; acidic monosaccharides cannot be determined. The technique of sugar analysis is applied to structural studies on natural compounds, e.g. the monosaccharide composition of lichenan and the carbohydrate moiety of the glycoproteins ovomucoid and Collocalia mucoid.

  19. Mining and milling of uranium ore: Indian scenario

    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)

  1. Sugar intolerance complicating acute gastroenteritis.

    Evans-Jones, G; McDowell, H P

    1986-01-01

    Sugar intolerance occurred in 31 of 200 children admitted to hospital with acute gastroenteritis. In 28 this was transient and settled rapidly, but in the remaining three it indicated a more serious and persistent problem. The most important predisposing factor was viral infection, in particular with rotavirus. The current regimen for the management of sugar intolerance complicating acute gastroenteritis at this hospital is outlined.

    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

  9. Uranium-mill appraisal program

    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

  10. Yang-Mills and Beyond

    Marateck, Samuel

    2011-01-01

    In their 1954 paper, Yang and Mills invented the non-Abelian field strength to satisfy certain criteria but didn't explain how it could be derived. In the penultimate section we show how the Yang-Mills field strength derives from Yang's gauge transformation. The preceding sections place Yang-Mills theory in historical perspective and cover material relating to the field strength. The final section shows how Yang-Mills theory was combined with spontaneous symmetry breaking, the Goldstone theorem and subsequent work to contribute to the Standard Model of particle physics.

    Matics, D.

    1981-10-01

    It is reported that a pilot plant has been constructed at Quivican, Cuba which is capable of producing up to 35 tons of mechanical pulp and approximately 35 tons of newsprint daily from bagasse. In addition to the experimental bagasse newspaper plant, the Cuban government is constructing a large bleached bagasse pulp and paper mill for production of 250 tons of bleached bagasse pulp and paper daily. The installation is scheduled to go into operation in early 1982. The United Nations Development Programme hopes that newsprint and other products which can be produced from the sugar cane stalk will lessen third world nations dependecy on an uncertain world sugar market and help stabilize their economy.

  14. Japan steel mill perspective

    Murase, K. [Kobe Steel Ltd., Tokyo (Japan)

    2004-07-01

    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.

  15. pH modulation and salivary sugar clearance of different chocolates in children: A randomized clinical trial

    SVSG Nirmala

    2016-01-01

    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.

  16. SWOT ANALYSIS OF INDIAN JUTE INDUSTRY

    G. KARTHIK AND N. RAMYA

    2012-11-01

    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.

  20. Micromorphological changes and mechanism associated with wet ball milling of Pinus radiata substrate and consequences for saccharification at low enzyme loading.

    Vaidya, Alankar A; Donaldson, Lloyd A; Newman, Roger H; Suckling, Ian D; Campion, Sylke H; Lloyd, John A; Murton, Karl D

    2016-08-01

    In this work, substrates prepared from thermo-mechanical treatment of Pinus radiata chips were vibratory ball milled for different times. In subsequent enzymatic hydrolysis, percent glucan conversion passed through a maximum value at a milling time of around 120min and then declined. Scanning electron microscopy revealed breakage of fibers to porous fragments in which lamellae and fibrils were exposed during ball milling. Over-milling caused compression of the porous fragments to compact globular particles with a granular texture, decreasing accessibility to enzymes. Carbon-13 NMR spectroscopy showed partial loss of interior cellulose in crystallites, leveling off once fiber breakage was complete. A mathematical model based on observed micromorphological changes supports ball milling mechanism. At a low enzyme loading of 2FPU/g of substrate and milling time of 120min gave a total monomeric sugar yield of 306g/kg of pulp which is higher than conventional pretreatment method such as steam exploded wood.

  3. Optimal concentration for sugar transport in plants

    Jensen, Kaare H.; Savage, Jessica A.; HOLBROOK, N. MICHELE

    2013-01-01

    Vascular plants transport energy in the form of sugars from the leaves where they are produced to sites of active growth. The mass flow of sugars through the phloem vascular system is determined by the sap flow rate and the sugar concentration. If the concentration is low, little energy is transferred from source to sink. If it is too high, sap viscosity impedes flow. An interesting question is therefore at which concentration is the sugar flow optimal. Optimization of sugar flow and transpor...

    HUYing-ning; WANGCheng-yong; WUXue-qi; QINZhe; ZENGBao-ping

    2004-01-01

    Tool wear and breakage of the micro-milling tool is an important problem for high speed machining of hardened steel die and mould. Dry milling of S136 hardened steel is carried out using TiA1N coated carbide micro-end mill (Ф2 mm). The effect of cutting speed, feed per tooth and radial depth of cut on cutting force is analyzed. Cutting parameters adapting to dry machining and strategy optimized for higher rate of material removal with lower cutting force are attained. Results of SEM observation show that the main failure patterns of micro-end mill are breakage of tool tip, wear and drop-off of surface coating, micro-chipping, and breakage of flank.

    The invention includes a method of dehydration of a sugar using a dehydration catalyst and a co-catalyst within a reactor. A sugar is introduced and H.sub.2 is flowed through the reactor at a pressure of less than or equal to about 300 psig to convert at least some of the sugar into an anhydrosugar product. The invention includes a process for producing isosorbide. A starting material comprising sorbitol is flowed into a reactor. H.sub.2 is counter flowed through the reactor. The starting material is exposed to a catalyst in the presence of a co-catalyst which comprises at least one metal. The exposing is conducted at a hydrogen pressure of less than or equal to 300 psig within the reactor and the hydrogen removes at least some of any water present during the exposing and inhibits formation of colored byproducts.

  9. The Efficiency Analyses of Croatian Sugar Industry by Using the Concept of Intellectual Capital

    Dražen Holmik

    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.

  11. Inorganic elements in sugar samples

    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.

    Gera, T; Khetarpaul, N

    2000-01-01

    Mean daily intake of all foods except cereals i.e. pulses, green leafy vegetables, roots and tubers, fruits, milk and milk products, sugar and fats of Indian obese male respondents was higher than the values recommended by Indian Council of Medical Research (ICMR, 1987). The consumption of fat and sugar was 18 and 8 percent more than the recommended intake values respectively. However, their non-obese counterparts consumed significantly (P vit B12, folacin, ascorbic acid and calcium by obese respondents was considerably higher than the recommended values (ICMR, 1990) and the control group. All the obese respondents were consuming adequate (100% and above) amounts of energy, protein and fats. Intake of carbohydrates was marginally adequate (75-99.9%) among 92 percent of the obese respondents whereas 8 percent were consuming adequate amount of carbohydrates. They had higher consumption of visible as well as invisible fat than the control group. PMID:11142609

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

    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.

  18. Pyrolytic sugars from cellulosic biomass

    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

  3. Sugar cane and sugar beet molasses, antioxidant-rich alternatives to refined sugar.

    Valli, Veronica; Gómez-Caravaca, Ana María; Di Nunzio, Mattia; Danesi, Francesca; Caboni, Maria Fiorenza; Bordoni, Alessandra

    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 α-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

  4. SUBAQUEOUS DISPOSAL OF MILL TAILINGS

    Neeraj K. Mendiratta; Roe-Hoan Yoon; Paul Richardson

    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

  7. YANG-MILLS FIELD CAPACITOR

    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. Natural radionuclides as dirt tracers in sugar cane consignments

    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 γ-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)

  9. The UK sugar tax - a healthy start?

    Jones, C M

    2016-07-22

    The unexpected announcement by the UK Chancellor of the Exchequer of a levy on sugar sweetened beverages (SSBs) on the 16 March 2016, should be welcomed by all health professionals. This population based, structural intervention sends a strong message that there is no place for carbonated drinks, neither sugared nor sugar-free, in a healthy diet and the proposed levy has the potential to contribute to both general and dental health. The sugar content of drinks exempt from the proposed sugar levy will still cause tooth decay. Improving the proposed tax could involve a change to a scaled volumetric tax of added sugar with a lower exemption threshold. External influences such as the Common Agricultural Policy and the Transatlantic Trade and Investment Partnership may negate the benefits of the sugar levy unless it is improved. However, the proposed UK sugar tax should be considered as a start in improving the nation's diet. PMID:27444594

  12. Einstein-Yang-Mills from pure Yang-Mills amplitudes

    Nandan, Dhritiman; Schlotterer, Oliver; Wen, Congkao

    2016-01-01

    We present new relations for scattering amplitudes of color ordered gluons and gravitons in Einstein-Yang-Mills theory. Tree-level amplitudes of arbitrary multiplicities and polarizations involving up to three gravitons and up to two color traces are reduced to partial amplitudes of pure Yang-Mills theory. In fact, the double-trace identities apply to Einstein-Yang-Mills extended by a dilaton and a B-field. Our results generalize recent work of Stieberger and Taylor for the single graviton case with a single color trace. As the derivation is made in the dimension-agnostic Cachazo-He-Yuan formalism, our results are valid for external bosons in any number of spacetime dimensions. Moreover, they generalize to the superamplitudes in theories with 16 supercharges.

  14. Colorado's prospectus on uranium milling

    The first part of this paper will discuss Colorado's control of uranium mill tailings under Titles I and II of the Uranium Mill Tailings Radiation Control Act of 1978. Colorado has a legacy of nine inactive mill sites requiring reclamation under Title I, and two presently active plus a number of new mill proposals which must be regulated in accordance with Title II. Past failures in siting and control on the part of federal jurisdictions have left the state with a heavy legacy requiring extensive effort to address impacts to the state's environment and population. The second part of this paper will discuss the remedial action programme authorized under Public Law 92-314 for Mesa Country, where lack of federal control led to the dispersal of several hundred thousand tons of uranium mill tailings on thousands of properties, including hundreds of homes, schools and other structures. Successful completion of the State efforts under both programmes will depend on a high level of funding and on the maintenance of adequate regulatory standards. (author)

  15. Cogeneration alternatives in sugar and alcohol industries. Case of study; Alternativas de cogeracao na industria sucro-alcooleira. Estudo de caso

    Sanchez Prieto, Mario Gabriel

    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.

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

    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

    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. (author)

  3. Combined fundamental and experimental approach to milling

    Starkey, Derek

    Air jet mills are important tools in the size reduction processing of pharmaceutical powders. The benefits of the air jet mill to the pharmaceutical industry are its sanitary design (no moving parts or media) and ability to produce narrow particle size distributions. Due to the high-value nature of active pharmaceutical ingredients, a trial-and-error approach to obtain optimal milling conditions for size reduction would lead to a needless expenditure of time and valuable resources. This work uses population balances for modeling the continuous milling of a spiral jet mill with inexpensive, readily available excipient powders, and predicts milling model parameters for high value powders with only small quantities being consumed. We have developed a multilevel model that describes the effect of material characteristics and mill operating variables on particle breakage in a specific air jet mill. This model allows us to predict product size distributions of brittle crystalline materials. The method used to develop this model can be utilized for many self-classifying mills. For a new mill, extensive initial milling with inexpensive excipient powders is required to determine mill-dependent model parameters. Subsequently, quick material characterization experiments can be made with limited powder consumption of expensive powders to determine powder-dependent milling parameters.

    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 $D>2$.

  11. YANG-MILLS FIELD AMPLIFIER

    Trunev A. P.

    2015-09-01

    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

    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

    2010-06-01

    Full Text Available Abstract Background Since sugarcane areas have increased rapidly in Brazil, the contribution of the sugarcane production, and, especially, of the sugarcane harvest system to the greenhouse gas emissions of the country is an issue of national concern. Here we analyze some data characterizing various activities of two sugarcane mills during the harvest period of 2006-2007 and quantify the carbon footprint of sugar production. Results According to our calculations, 241 kg of carbon dioxide equivalent were released to the atmosphere per a ton of sugar produced (2406 kg of carbon dioxide equivalent per a hectare of the cropped area, and 26.5 kg of carbon dioxide equivalent per a ton of sugarcane processed. The major part of the total emission (44% resulted from residues burning; about 20% resulted from the use of synthetic fertilizers, and about 18% from fossil fuel combustion. Conclusions The results of this study suggest that the most important reduction in greenhouse gas emissions from sugarcane areas could be achieved by switching to a green harvest system, that is, to harvesting without burning.

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

    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

    John Stuart Mill dominates contemporary pornography debates where he is routinely invoked as an authoritative defence against regulation. This article, by contrast, argues that a broader understanding of Mill's ethical liberalism, his utilitarianism, and his feminism casts doubt over such an assumption. New insights into Mill's approach to sex, sexual activity, and the regulation of prostitution reveal an altogether more nuanced and activist approach. We conclude that John Stuart Mill would a...

It also generates a large amount of lignocellulosic wastes, mainly in the form of empty fruit bunches, press cake fibres and nut shell. Research efforts at PORIM have been directed towards the utilisation of these wastes as a means to solve the problem of environmental pollution as well as for the generation of economic returns for the mills. We have studied a thermophilic contact process for the anaerobic digestion of palm oil mill effluent and its potential for generating biogas for energy uses. Our work has also shown that the condensate derived from the fruit sterilisation process during milling is amenable to fermentation for the production of single cell protein (SCP) and exo-enzymes. The enzymes produced have been applied for oil clarification, oil recovery from press cake fibers and saccharification of the fibers for the production of sugar feedstocks. This paper will also introduce the concept of integrated waste management for the palm oil mill through the implementation of these technologies.

  8. Scientists Discover Sugar in Space

    2000-06-01

    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

  9. J. S. Mill on Education

    Ryan, Alan

    2011-01-01

    Mill may be said either to have written rather little on education or to have written a very great deal. He himself distinguished between a "narrow" and a "wider" sense of education, the former limited to what happens in formal educational settings, the latter embracing all the influences that make us who and what we are. He wrote rather little on…

  10. DETERMINATION OF PRIMARY METABOLITES IN CEREAL MILLING FRACTIONS

    Eva Ivanišová

    2013-10-01

    Full Text Available The aim of this study was to determine of primary metabolites (content of starch, total dietary fibre, reducing sugars, proteins and amino acids in four milling fractions of selected cereals (barley, wheat, oat, spelt, rye, triticale grew in the year 2009. It was found that flour fractions (break flour and reduction flour showed the lower content of primary metabolites than bran fractions (fine bran and coarse bran. The aim of this study was also to mention the potential use of bran parts of grain - substances from these parts can be isolated and after treatment, which causes their efficiently usable for human body, they can be used for fortification of wide range of food products.
