Full Text Available Agro-industry has an important role in Indonesian economic growth. One of the crucial constraints in agro-industry investments in developing country is due to limited access to investment fund. This research was aimed to analyze the impacts of leverage on the agro-industrial company investments. The research used financial report data of the manufacturing industries on agro-industrial bases registered in Indonesian Stock-Exchange from 2007 to 2016. The data were analyzed using panel data regression analysis. The results of the research showed that the leverage influenced negatively on the agro-industrial companies. Cash flow has a negative impact on the company investments, which shows the existence of financial constraints when the company decide to invest.

This paper presents a study of cement replacement by sugar cane bagasse ash (SCBA) in industrial scale aiming to reduce the CO(2) emissions into the atmosphere. SCBA is a by-product of the sugar/ethanol agro-industry abundantly available in some regions of the world and has cementitious properties indicating that it can be used together with cement. Recent comprehensive research developed at the Federal University of Rio de Janeiro/Brazil has demonstrated that SCBA maintains, or even improves, the mechanical and durability properties of cement-based materials such as mortars and concretes. Brazil is the world's largest sugar cane producer and being a developing country can claim carbon credits. A simulation was carried out to estimate the potential of CO(2) emission reductions and the viability to issue certified emission reduction (CER) credits. The simulation was developed within the framework of the methodology established by the United Nations Framework Convention on Climate Change (UNFCCC) for the Clean Development Mechanism (CDM). The State of São Paulo (Brazil) was chosen for this case study because it concentrates about 60% of the national sugar cane and ash production together with an important concentration of cement factories. Since one of the key variables to estimate the CO(2) emissions is the average distance between sugar cane/ethanol factories and the cement plants, a genetic algorithm was developed to solve this optimization problem. The results indicated that SCBA blended cement reduces CO(2) emissions, which qualifies this product for CDM projects. 2010 Elsevier Ltd. All rights reserved.

Dean, E; Ross, J

1993-08-01

Although canes are among the most commonly used mobility aids, little is known about the relationship between cane prescription and effectiveness. The purpose of this study was to examine the relationships among cane fitting (ie, cane fitter, cane band, and cane length), reported improvements in function, and reduction in falls. Cane users living in the community (86 women and 58 men with a median age distribution of 61 to 80 years) and sampled from seven urban shopping centers in British Columbia, Canada, participated in the study. The primary reasons cited for using a cane were joint problems (39%), general balance difficulties (30%), and a combination of joint and balance problems (15%). Measures included appropriateness of cane length and responses to closed-ended questions related to qualifications of the cane fitter, cane band, functional ability with a cane, and falling frequency. Overall, cane use was associated with improved confidence and functional ability. Canes fitted by health care workers approximated the clinically recommended length compared with canes fitted by non-health care workers, which tended to be greater than this length. There was no relationship, however, between cane fitting (cane fitter, cane hand, and appropriateness of cane length) and functional ability with a cane and falling frequency [corrected]. We concluded that health care workers may need to reconsider the variables for optimal cane prescription and their specifications for a given individual. The notion of a correct length and cane hand, for example, may be less important than factors such as the indications for cane use, comfort, and enhanced confidence.

Since one of the restrictive problems when investing in energy saving is the uncertainty of obtaining the planed savings, a technique in the risk handling for energy efficiency projects, called Insurance for the Energy Saving (IES) is presented. IES economically stimulates those who implement projects for energy saving so they go beyond the normal measures and really obtain significant saving levels, thus contributing to the fulfillment of national objectives in energy saving. In order to reduce the risk of low performance in energy caused by saving projects there exist the international performance measurement and the protocol of investment (IMPVP) as well as diagnoses and starting processes, whereas in order to transfer the financial risk that a saving project represents, mechanisms such as FDIC insurance, conversion of the debt in values, Saving's Guarantees, Performance Bonuses or Guarantee Bonuses and Insurances for Energy Saving can be of great help. This article deals on the IES insurance policies, their loss control management, successful cases, benefits, particular advantages, place in the market and refers argued insurance exceptions and perception surveys.

This study examined the effect of cane tips and cane techniques on drop-off detection with the long cane. Blind pedestrians depend on a long cane to detect drop-offs. Missing a drop-off may result in falls or collision with moving vehicles in the street. Although cane tips appear to affect a cane user's ability to detect drop-offs, few experimental studies have examined such effect. A repeated-measures design with block randomization was used for the study. Participants were 17 adults who were legally blind and had no other disabilities. Participants attempted to detect the drop-offs of varied depths using different cane tips and cane techniques. Drop-off detection rates were similar between the marshmallow tip (77.0%) and the marshmallow roller tip (79.4%) when both tips were used with the constant contact technique, p = .294. However, participants detected drop-offs at a significantly higher percentage when they used the constant contact technique with the marshmallow roller tip (79.4%) than when they used the two-point touch technique with the marshmallow tip (63.2%), p marshmallow roller tip (perceived as a less advantageous tip) was more effective than the two-point touch technique used with a marshmallow tip (perceived as a more advantageous tip) in detecting drop-offs. The findings of the study may help cane users and orientation and mobility specialists select appropriate cane techniques and cane tips in accordance with the cane user's characteristics and the nature of the travel environment.

Full Text Available The mushroom Pleurotus ostreatus has nutritional and medicinal characteristics that depend on the growth substrate. In nature, this fungus grows on dead wood, but it can be artificially cultivated on agricultural wastes (coffee husks, eucalyptus sawdust, corncobs and sugar cane bagasse. The degradation of agricultural wastes involves some enzyme complexes made up of oxidative (laccase, manganese peroxidase and lignin peroxidase and hydrolytic enzymes (cellulases, xylanases and tanases. Understanding how these enzymes work will help to improve the productivity of mushroom cultures and decrease the potential pollution that can be caused by inadequate discharge of the agroindustrial residues. The objective of this work was to assess the activity of the lignocellulolytic enzymes produced by two P. ostreatus strains (PLO 2 and PLO 6. These strains were used to inoculate samples of coffee husks, eucalyptus sawdust or eucalyptus bark add with or without 20 % rice bran. Every five days after substrate inoculation, the enzyme activity and soluble protein concentration were evaluated. The maximum activity of oxidative enzymes was observed at day 10 after inoculation, and the activity of the hydrolytic enzymes increased during the entire period of the experiment. The results show that substrate composition and colonization time influenced the activity of the lignocellulolytic enzymes.

A challenge facing the biofuel industry is to develop an economically viable and sustainable biorefinery. The existing potential biorefineries in Louisiana, raw sugar mills, operate only 3 months of the year. For year-round operation, they must adopt other feedstocks, besides sugar cane, as supplemental feedstocks. Energy cane and sweet sorghum have different harvest times, but can be processed for bio-ethanol using the same equipment. Juice of energy cane contains 9.8% fermentable sugars and that of sweet sorghum, 11.8%. Chemical composition of sugar cane bagasse was determined to be 42% cellulose, 25% hemicellulose, and 20% lignin, and that of energy cane was 43% cellulose, 24% hemicellulose, and 22% lignin. Sweet sorghum was 45% cellulose, 27% hemicellulose, and 21% lignin. Theoretical ethanol yields would be 3,609 kg per ha from sugar cane, 12,938 kg per ha from energy cane, and 5,804 kg per ha from sweet sorghum.

The use of plant tissue culture and the application of gamma radiation as mutation inducing agents, in the sugar cane plant, variety NA 5679, are studied. The variation in the contents of brix, pol, fiber, purity, extraction, phosphorus, nitrogen, reducing sugars as well as the morphological characteristics are analysed. The 'callus' obtained by the tissue culture were irradiated with 20, 40, and 60 Gy doses. The statistical analysis indicated that the method of tissue culture may, eventually, increase the contents of the technological parameters and the dosages of gamma radiation were not efficient for such purpose.

This paper introduces the new concept of an electronic cane for blind people. While some systems inform the subject only of the presence of the object and its relative distance, RecognizeCane is also able to recognize most common objects and environment clues to increase the safety and confidence of the navigation process. The originality of RecognizeCane is the use of simple sensors, such as infrared, brilliance or water sensors to inform the subject of the presence, for example, of a stairway, a water puddle, a zebra crossing or a trash can. This cane does not use an embedded vision system. RecognizeCane is equipped with several sensors and microprocessors to collect sensor data and extract the desired information about the close environment by means of a dynamic analysis of output signals.

In the present study, solid-state fermentation for the production of raw starch degrading enzyme was investigated by thermotolerant Rhizopus microsporus TISTR 3531 using a combination of agro-industrial wastes as substrates. The obtained crude enzyme was applied for hydrolysis of raw cassava starch and chips at low temperature and subjected to nonsterile ethanol production using raw cassava chips. The agro-industrial waste ratio was optimized using a simplex axial mixture design. The results showed that the substrate mixture consisting of rice bran:corncob:cassava bagasse at 8 g:10 g:2 g yielded the highest enzyme production of 201.6 U/g dry solid. The optimized condition for solid-state fermentation was found as 65% initial moisture content, 35°C, initial pH of 6.0, and 5 × 10 6 spores/mL inoculum, which gave the highest enzyme activity of 389.5 U/g dry solid. The enzyme showed high efficiency on saccharification of raw cassava starch and chips with synergistic activities of commercial α-amylase at 50°C, which promotes low-temperature bioethanol production. A high ethanol concentration of 102.2 g/L with 78% fermentation efficiency was achieved from modified simultaneous saccharification and fermentation using cofermentation of the enzymatic hydrolysate of 300 g raw cassava chips/L with cane molasses.

Sandra Regina Ceccato-Antonini

Full Text Available ABSTRACT: The main interest in the energy cane is the bioenergy production from the bagasse. The juice obtained after the cane milling may constitute a feedstock for the first-generation ethanol units; however, little attention has been dedicated to this issue. In order to verify the feasibility of the energy cane juice as substrate for ethanol production, the objectives of this research were first to determine the microbiological characteristics and deterioration along the time of the juices from two clones of energy cane (Type I and second, their fermentability as feedstock for utilization in ethanol distilleries. There was a clear differentiation in the bacterial and yeast development of the sugarcane juices assayed, being much faster in the energy canes than in sugarcane. The storage of juice for 8 hours at 30oC did not cause impact in alcoholic fermentation for any sample analyzed, although a significant bacterial growth was detected in this period. A decrease of approximately seven percentage points in the fermentative efficiency was observed for energy cane juice in relation to sugarcane in a 24-hour fermentation cycle with the baking yeast. Despite the faster deterioration, the present research demonstrated that the energy cane juice has potential to be used as feedstock in ethanol-producing industries. As far as we know, it is the first research to deal with the characteristics of deterioration and fermentability of energy cane juices.

Sugar cane is a major source of food and fuel worldwide. Biotechnology has the potential to improve economically-important traits in sugar cane as well as diversify sugar cane beyond traditional applications such as sucrose production. High levels of transgene expression are key to the success of improving crops through biotechnology. Here we describe new molecular tools that both expand and improve gene expression capabilities in sugar cane. We have identified promoters that can be used to drive high levels of gene expression in the leaf and stem of transgenic sugar cane. One of these promoters, derived from the Cestrum yellow leaf curling virus, drives levels of constitutive transgene expression that are significantly higher than those achieved by the historical benchmark maize polyubiquitin-1 (Zm-Ubi1) promoter. A second promoter, the maize phosphonenolpyruvate carboxylate promoter, was found to be a strong, leaf-preferred promoter that enables levels of expression comparable to Zm-Ubi1 in this organ. Transgene expression was increased approximately 50-fold by gene modification, which included optimising the codon usage of the coding sequence to better suit sugar cane. We also describe a novel dual transcriptional enhancer that increased gene expression from different promoters, boosting expression from Zm-Ubi1 over eightfold. These molecular tools will be extremely valuable for the improvement of sugar cane through biotechnology.

Van Ranst, E.

1999-01-01

Full Text Available The potential yields of irrigated and of rainfed sugar-cane on three ferrallitic soil series, well represented in the Nkoteng sugar-cane estate of Central Cameroon, are estimated following different methods. The potential yield of irrigated sugar-cane is estimated from the total maximum evapotranspiration during the crop cycle. The potential yield of rainfed sugar-cane is estimated following two methods for the establishment of a water balance and for the determination of a yield reduction as a result of a water deficit. The calculated potential yields are higher than the observed ones. The yield reduction due to rain fed cropping can mainly be attributed to water shortage during the late yield formation and the ripening periods. A supplementary yield decline is due to a combined action of an acid soil reaction, a possible Al-toxicity a low base saturation, an inadequate CEC, organic matter content and P-availability which may adequately explain the actual yield level.

The purpose of this cross-sectional study is to provide basic but essential information about how older cane users obtain their canes and how they use these canes for their daily mobility, since there is still lack of information on these areas. Ninety-three older (≥65 years old) subjects who use canes for daily activities were recruited from four assisted living facilities and five retirement centers for this cross-sectional study. The assessment involved interviewing cane users with a questionnaire, examining their canes, and investigating how these canes were used by their owners during ambulation. The commonly used canes are (from most to least): adjustable single-tip, un-adjustable (wooden), small quad, and large quad. Five major problems from data analysis were identified: lack of medical consultation for device selection/use, incorrect cane height/maintenance, placement of cane in improper hand, inability to maintain the proper reciprocal gait pattern, and improper posture during ambulation. Only forward-leaning posture during ambulation might be associated with increased falls among the older cane users. Knowledge of these problems could assist health professionals to implement appropriate interventions in clinical settings and to provide community service to address all problems related to cane use.

Dirt level in sugar cane consignments delivered to the factory is dependent on soil type, in association with harvesting system and weather conditions. Efforts for reducing soil in harvested cane have been made by sugar cane millers, especially improving the washing system installed before crushing. Instrumental neutron activation analysis has shown its potential for assessing dirt reductions in the washed material. Knowledge of elemental concentrations in the different soil fractions highlights the reliability of such measurements especially when taking into account the soil characteristics. (author)

The tons of organic waste that are annually generated by agro-industry, can be used as raw material for methane production. For this reason, it is important to previously perform biodegradability tests to organic wastes for their full scale methanization. This paper addresses biodegradability, methane production and the behavior of populations of eubacteria and archaeabacteria during anaerobic digestion of banana, mango and papaya agroindustrial wastes. Mango and banana wastes had higher organic matter content than papaya in terms of their volatile solids and total solid rate (94 and 75% respectively). After 63 days of treatment, the highest methane production was observed in banana waste anaerobic digestion: 63.89ml CH4/per gram of chemical oxygen demand of the waste. In the PCR-DGGE molecular analysis, different genomic footprints with oligonucleotides for eubacteria and archeobacteria were found. Biochemical methane potential results proved that banana wastes have the best potential to be used as raw material for methane production. The result of a PCR- DGGE analysis using specific oligonucleotides enabled to identify the behavior of populations of eubacteria and archaeabacteria present during the anaerobic digestion of agroindustrial wastes throughout the process.

Biorefinery of sugar cane is the first economic activity of Reunion Island. Some sugar cane manufactured products (juice, syrup, molasses) have antioxidant activities and are sources of both phenolic compounds and Maillard Reaction Products (MRP). The study aimed to highlight the global antioxidant activity of sugar cane stillage and understand its identity. Chromatographic fractionation on Sephadex LH-20 resin allowed the recovery of a MRP-rich fraction, responsible for 58 to 66% of the global antioxidant activity according to the nature of the sugar cane stillage (DPPH test), and a phenolic compounds-rich fraction for 37 to 59% of the activity. A good correlation was recorded between the antioxidant activity of the sugar cane stillage and its content in total reducing compounds amount (Folin-Ciocalteu assay), among them 2.8 to 3.9 g/L of phenolic compounds (in 5-caffeoylquinic acid equivalent). Preliminary experiments by HPLC-DAD-MS allowed to identify several free phenolic acids and gave clues to identify esters of quinic acids.

An analytical ultrasound-assisted extraction (UAE) method has been optimized and validated for the rapid extraction of stilbenes from grape canes. The influence of sample pre-treatment (oven or freeze-drying) and several extraction variables (solvent, sample-solvent ratio and extraction time between others) on the extraction process were analyzed. The new method allowed the main stilbenes in grape canes to be extracted in just 10 min, with an extraction temperature of 75 °C and 60% ethanol in water as the extraction solvent. Validation of the extraction method was based on analytical properties. The resulting RSDs (n = 5) for interday/intraday precision were less than 10%. Furthermore, the method was successfully applied in the analysis of 20 different grape cane samples. The result showed that grape cane byproducts are potentially sources of bioactive compounds of interest for pharmaceutical and food industries.

To study whether a cane improved balance recovery after perturbation during walking. This study was a crossover comparison comparing the effect of walking with and without a cane for balance recovery after perturbation during treadmill walking. Five normal young volunteers participated. The velocity and acceleration of a marker sited on the seventh cerebral vertebra (C7) and vertical hand motion were measured by a motion analysis system. When using a cane, C7 backward velocity increased by approximately 15% (413 SD 95 mm/s with cane vs. 358 SD 88 mm/s without). In addition, C7 backward acceleration increased by approximately 23% (3.2 SD 0.7 m/s(2) with cane vs. 2.6 SD 0.8 m/s(2) without) and the vertical motion of the right hand decreased (187 SD 98 mm with cane vs. 372 SD 260 mm without). Additionally, no subject was able to use a cane to broaden their base of support. The ability to limit trunk extension is crucial for preventing falls. Therefore, using a cane jeopardizes recovery from backward balance loss. The results encourage further research on the risk of a cane on balance recovery for the elderly population and habitual cane users.

The aim of this study was to determine the effect of using a cane on movement time, joint moment, weight symmetry, and muscle activation patterns during sit-to-stand (STS) transfer in healthy subjects and subjects who have had a stroke. Nine subjects with hemiparesis (mean [SD] age, 61.11 [12.83] yrs) and nine healthy adults (mean [SD] age, 63.11 [10.54] yrs) were included. The subjects with hemiparesis performed STS transfer in two randomly assigned conditions: (1) without a cane and (2) with a cane. The healthy subjects performed only STS transfer without a cane. A three-dimensional motion system, force plates, and eletromyography were used to examine STS transfer. The symmetry index between the two limbs was calculated. The movement time of the subjects with hemiparesis in both conditions without a cane and with a cane was longer than that of the healthy subjects without a cane (P hemiparesis resulted in shorter movement time, greater knee extensor moment of the paretic limb, and more symmetry of weight bearing than in those without a cane (P hemiparesis. Cane use may promote more symmetrical STS transfers rather than compensation by the unaffected limb.

Full Text Available The present paper is aiming to provide an actual state of the development of non autoclaved Agro-Industrial aerated concrete by using multiple ashes as improvement of thermal behavior for building. The feasibility of Agro-Industrial wastes as lightweight concrete by utilizing the Palm Oil Fuel Ash (POFA as binder replacement and bottom ash as fine aggregate was investigated in this paper. Portland cement, bottom ash, aluminum powder and lime (Ca(OH2 were used in this study. The POFA was used to replace Portland cement and Hydrated Lime at 0%, 5%, 10% and 15% by weight and aluminum powder was added at 0.75% dry weight in order to form bubbles. The compressive strength, water absorption, porosity and the thermal conductivity test were carried out after the concrete were water cured for 7 days and later being exposed to the air and water until 28days. The results show that the 20% replacements give the optimum strength of 7.143MPa and 30% give the best thermal conductivity with 0.48W/mK. Hence, this study aim, was to develop an agro-industrial aerated concrete good in insulation but having an optimum strength. Hence, it has been found that the more the percentage of POFA is added the lower the thermal conductivity since the pore structure is increasing and by the optimization done, 30% replacement has been chosen as the best mix design for Agro-Industrial Aerated Concrete.

Full Text Available The use of other inducers as substitutes for pectin was studied aiming to reduce the production costs of pectic enzymes. The effects of sugar-cane juice on the production of pectin lyase (PL and polygalacturonase (PG by Penicillium griseoroseum were investigated. The fungus was cultured in a mineral medium (pH 6.3 in a rotary shaker (150 rpm for 48 h at 25oC. Culture media were supplemented with yeast extract and sucrose or sugar-cane juice. Sugar-cane juice added singly to the medium promoted higher PL activity and mycelial dry weight when compared to pectin and the use of sugar-cane juice and yeast extract yielded levels of PG activity that were similar to those obtained with sucrose-yeast extract or pectin. The results indicated that, even at low concentrations, sugar-cane juice was capable of inducing pectin lyase and polygalacturonase with no cellulase activity in P. griseoroseum.

The effects of land-use change (LUC) on soil carbon (C) balance has to be taken into account in calculating the CO2 savings attributed to bioenergy crops. There have been few direct field measurements that quantify the effects of LUC on soil C for the most common land-use transitions into sugar cane in Brazil, the world's largest producer . We quantified the C balance for LUC as a net loss (carbon debt) or net gain (carbon credit) in soil C for sugar-cane expansion in Brazil. We sampled 135 field sites to 1 m depth, representing three major LUC scenarios. Our results demonstrate that soil C stocks decrease following LUC from native vegetation and pastures, and increase where cropland is converted to sugar cane. The payback time for the soil C debt was eight years for native vegetation and two to three years for pastures. With an increasing need for biofuels and the potential for Brazil to help meet global demand, our results will be invaluable for guiding expansion policies of sugar-cane production towards greater sustainability.

Corrosion of Modified Concrete with Sugar Cane Bagasse Ash

R. E. Núñez-Jaquez

2012-01-01

Full Text Available Concrete is a porous material and the ingress of water, oxygen, and aggressive ions, such as chlorides, can cause the passive layer on reinforced steel to break down. Additives, such as fly ash, microsilica, rice husk ash, and cane sugar bagasse ash, have a size breakdown that allows the reduction of concrete pore size and, consequently, may reduce the corrosion process. The objective of this work is to determine the corrosion rate of steel in reinforced concrete by the addition of 20% sugar cane bagasse ash by weight of cement. Six prismatic specimens (7×7×10 cm with an embedded steel rod were prepared. Three contained 20% sugar cane bagasse ash by weight of cement and the other three did not. All specimens were placed in a 3.5% NaCl solution and the corrosion rate was determined using polarization resistance. The results showed that reinforced concrete containing sugar cane bagasse ash has the lowest corrosion rates in comparison to reinforced concrete without the additive.

The influence of agro-industrial effluents on River Nile pollution

Directory of Open Access Journals (Sweden)

Sayeda M. Ali

2011-01-01

Full Text Available The major agro-industrial effluents of sugarcane and starch industries pose a serious threat to surface waters. Their disposal in the River Nile around Cairo city transitionally affected the microbial load. In situ bacterial enrichment (50–180% was reported and gradually diminished downstream; the lateral not vertical effect of the effluent disposal was evident. Disposed effluents increased BOD and COD, and then progressively decreased downstream. Ammoniacal N was elevated, indicating active biological ammonification and in situ biodegradability of the effluents. In vitro, the nitrogen-fixing rhizobacteria Crysomonas luteola, Azospirillum spp., Azomonas spp. and K. pneumoniae successfully grew in batch cultures prepared from the crude effluents. This was supported by adequate growth parameters and organic matter decomposition. Therefore, such biodegradability of the tested agro-industrial effluents strongly recommends their use for microbial biomass necessary for the production of bio-preparates.

Full Text Available Ice cream is a tasty and nutritious source of protein and calcium, but it is deficient in some minerals, as iron, but it is found in sugar cane juice, which is a source of minerals such as iron, phosphorus, calcium, sodium among others. The objective of the present study are: to develop sugar cane juice ice cream, in order to increase the mineral content replacing refined sugar and water during the manufacturing process by sugar cane juice; to analyze its physical-chemical composition; to check your sensory acceptance with children. Three formulations were prepared from sugar cane juice ice cream: sugar cane juice ice cream (SC, sugar cane juice ice cream with molasses (SCM and sugar cane juice ice cream with brown sugar (SCR. Sensory evaluation was conducted with 120 children (62 boys and 58 girls from 8 to 10 years old, students from 3rd to 5th years of primary school. Sensory tests were ordering-preference, intention to use and acceptance with facial hedonic scale of 7 points. The results of physico-chemical and acceptance testing were statistically analyzed by analysis of variance (ANOVA, the scores compared by Tukey test (p ? 0.05 and the result of the sensory test ordering-preference were assessed using the Friedman. The ice cream it presents has a reduced fat content because it was formulated with palm trans-fat free. The use of sugar cane juice in the formulation of the ice cream increased the amount of minerals when compared to ordinary ice cream. Therefore, sugar cane juice ice cream demonstrated to be more healthy and nutritious compared with traditional ice cream, besides being source of calcium, iron and phosphorus; serving the needs of the recommended daily intake (IDR for children from 7 to 10 years old. About the sensory evaluation, all formulations of sugar cane juice ice cream obtained great sensory acceptance among children in all sensory attributes evaluated, showing excellent percentages of acceptance and intention to use by

Haptic Cues for Balance: Use of a Cane Provides Immediate Body Stabilization

Directory of Open Access Journals (Sweden)

Stefania Sozzi

2017-12-01

Full Text Available Haptic cues are important for balance. Knowledge of the temporal features of their effect may be crucial for the design of neural prostheses. Touching a stable surface with a fingertip reduces body sway in standing subjects eyes closed (EC, and removal of haptic cue reinstates a large sway pattern. Changes in sway occur rapidly on changing haptic conditions. Here, we describe the effects and time-course of stabilization produced by a haptic cue derived from a walking cane. We intended to confirm that cane use reduces body sway, to evaluate the effect of vision on stabilization by a cane, and to estimate the delay of the changes in body sway after addition and withdrawal of haptic input. Seventeen healthy young subjects stood in tandem position on a force platform, with eyes closed or open (EO. They gently lowered the cane onto and lifted it from a second force platform. Sixty trials per direction of haptic shift (Touch → NoTouch, T-NT; NoTouch → Touch, NT-T and visual condition (EC-EO were acquired. Traces of Center of foot Pressure (CoP and the force exerted by cane were filtered, rectified, and averaged. The position in space of a reflective marker positioned on the cane tip was also acquired by an optoelectronic device. Cross-correlation (CC analysis was performed between traces of cane tip and CoP displacement. Latencies of changes in CoP oscillation in the frontal plane EC following the T-NT and NT-T haptic shift were statistically estimated. The CoP oscillations were larger in EC than EO under both T and NT (p < 0.001 and larger during NT than T conditions (p < 0.001. Haptic-induced effect under EC (Romberg quotient NT/T ~ 1.2 was less effective than that of vision under NT condition (EC/EO ~ 1.5 (p < 0.001. With EO cane had little effect. Cane displacement lagged CoP displacement under both EC and EO. Latencies to changes in CoP oscillations were longer after addition (NT-T, about 1.6 s than withdrawal (T-NT, about 0.9 s of haptic

The aim of this study was to assess the seasonal price of sugar cane, fuel alcohol (hydrated and anhydrous) and electricity tariffs as a way of aiding tool for optimization of energy generation, using biomass originating from cane sugar. Using the method of moving average centered was concluded that cane and electricity rates were close to seasonal average, with low range of prices, suggesting the non-occurrence of seasonal variation in prices. Unlike the seasonal indices of ethanol showed seasonal variation of prices with greater amplitude of seasonal index. Thus, the results suggest that the utilization of by-products of sugar cane to produce electrical power points to the prospect of reducing risks associated with variations in the price of ethanol, thereby contributing to greater stability and possibility to those involved in planning alcohol sector.

2010-01-01

In recent years, citrus national agroindustries have shown a significant momentum, led by the market expansion of fruit derivatives. This activity has resulted in the generation of large amounts of waste, which could have a potential as starting material for the development of commercial products with high added value such as essential oils (EO), fixed oils, and fibres among others. The EO have a strong demand in the food industry, pharmaceuticals, and cosmetics. This paper describes the extraction and characterization of mandarin EO obtained through steam distillation, of agroindustrial waste. The effect of vapour pressure, thickness, and the number of layers of plant material, were evaluated on the yield and quality of EO. The operating conditions were adjusted in accordance to the design characteristics of the extraction plant of a local company.

Lopez, J M; Priego, A; Wilson, A; Preston, T R

1977-01-01

Two experiments were carried out. In the first, 40 Zebu bulls in groups of 5 were used in a 2 x 2 factorial design to study the following main treatments in a basal feed of chopped whole sugar cane and urea: (1) 500 or 1000 g/day of rice polishings; (2) mixing the supplement with the sugar cane or giving it as a separate meal before the cane was offered. In the second experiment, a changeover design was used with 3 rumen - cannulated Zebu bulls to study the effect on rumen fermentation of giving the rice polishings (500 g/day) mixed with the sugar cane or as a separate meal. In experiment 1, the rate of liveweight gain was increased from 421 to 559 g/day by the higher level of supplementation with rice polishings but there were no differences due to the method of giving this supplement. Voluntary dry matter intake was increased by the higher level of supplementation and there was an improvement in feed conversion. Neither of these parameters was affected by the method of giving the rice polishings. In the second experiment, there was an indication of slightly lower values for pH of rumen fluid between 11:00 am and 5:00 pm, but no effects on the molar proportion of the VFA (volatile fatty acids), when rice polishings were given as a separate meal rather than mixed in the cane. There were significant changes in molar proportions of VFA with time of sampling, with increases in C/sub 3/ and decreases in C/sub 2/ after feeding; C/sub 4/ molar proportions did not change.

Bacchi, M.A.; Fernandes, E.A.N.

1998-01-01

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, 212 Pb 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)

Characteristics of fermentation of refined cane sugar syrup for alcohol

Energy Technology Data Exchange (ETDEWEB)

Raev, Z A; Bazilevich, K K

1956-01-01

Technological properties of cane sugar syrup, obtained on refining of raw cane sugar, were investigated. Its poor fermentation is caused by the lack of nitrous substances (1/10 as much as in sugar beet) necessary for the nutrition of yeast. It is necessary to introduce into the mixture of yeast and must 0.8% (NH/sub 4/)/sub 2/SO/sub 4/ based on weight of syrup (at a permanent aeration the assimilability of N from (NH/sub 4/)/sub 2/SO/sub 4/ by the yeast will be higher and the dosage has to be increased), 1% of superphosphate or 0.12% of a 70% phosphoric acid solution, and 0.5% of a yeast autolyst. For the fermentation of cane sugar syrup the mixture of yeast and must has to be prepared with a concentration of 10 to 11/sup 0/ by the saccharometer scale, but the average initial concentration of the fermentive must has to be 17 to 18/sup 0/ with the intention to keep the alcohol content of the ripe must at 8.7 to 8.8% by volume. Considering the low buffer ability of the syrup from cane sugar, the acidity of the must, mixed with yeast, has to be kept less than or equal to 0.4 to 0.5/sup 0/, the pH at 4.6 to 4.8; on a higher acidity the pH drops to a value which inhibits the fission of the yeast cells. On a joint fermentation of syrup from sugar cane and sugar beets 1% of superphosphate in the form of an aqueous extract and an autolyst of yeast in an amount of 0.5% of the weight of syrup was introduced into the must; the yield of alcohol from cane sugar syrup increased compared with the yield on separate processing.

Can use of walkers or canes impede lateral compensatory stepping movements?

Science.gov (United States)

Bateni, Hamid; Heung, Evelyn; Zettel, John; McLlroy, William E; Maki, Brian E

2004-08-01

Although assistive devices, such as walkers and canes are often prescribed to aid in balance control, recent studies have suggested that such devices may actually increase risk of falling. In this study, we investigated one possible mechanism: the potential for walkers or canes to interfere with, or constrain, lateral movement of the feet and thereby impede execution of compensatory stepping reactions during lateral loss of balance. Lateral stepping reactions were evoked, in 10 healthy young adults (ages 22-27 years), by means of sudden unpredictable medio-lateral support surface translation. Subjects were tested while holding and loading a standard pickup walker or single-tip cane or while using no assistive device (hands free or holding an object). Results supported the hypothesis that using a walker or cane can interfere with compensatory stepping. Collisions between the swing-foot and mobility aid were remarkably frequent when using the walker (60% of stepping reactions) and also occurred in cane trials (11% of stepping reactions). Furthermore, such collisions were associated with a significant reduction (26-37%) in lateral step length. It appeared that subjects were sometimes able to avoid collision by increasing the forward or backward displacement of the swing-foot or by moving the cane; however, attempts to lift the walker out of the way occurred rarely and were usually impeded due to collision between the contralateral walker post and stance foot. The fact that compensatory stepping behavior was altered significantly in such a healthy cohort clearly demonstrates some of the safety limitations inherent to these assistive devices, as currently designed.

This paper presents some of the fundamental issues related to energy conservation programs in general and to the petroleum industry in particular with the purpose of integrating them both, that is, considering not only the energy issues, but also the ecological and economical aspects. This is achieved by using the two fundamental laws of thermodynamics (the science that studies energy, its characteristics, and its transformations) through the use of the exergy concept, which is a measure of the energy quality and of its withdrawal with respect to the environment. The origins of the present-day technologies, regarding energy conservation, the short, medium and long term general strategies and the implementation stages of the integral programs of energy conservation are presented, and it concludes with a series of general policies aimed at making the energy conservation programs more congruent with the maintenance of a sustainable development.

Independent mobility is one of the most pressing problems facing people who are blind. We present the EyeCane, a new mobility aid aimed at increasing perception of environment beyond what is provided by the traditional White Cane for tasks such as distance estimation, navigation and obstacle detection. The "EyeCane" enhances the traditional White Cane by using tactile and auditory output to increase detectable distance and angles. It circumvents the technical pitfalls of other devices, such as weight, short battery life, complex interface schemes, and slow learning curve. It implements multiple beams to enables detection of obstacles at different heights, and narrow beams to provide active sensing that can potentially increase the user's spatial perception of the environment. Participants were tasked with using the EyeCane for several basic tasks with minimal training. Blind and blindfolded-sighted participants were able to use the EyeCane successfully for distance estimation, simple navigation and simple obstacle detection after only several minutes of training. These results demonstrate the EyeCane's potential for mobility rehabilitation. The short training time is especially important since available mobility training resources are limited, not always available, and can be quite expensive and/or entail long waiting periods.

OF AGROINDUSTRIAL COMPLEX MANAGEMENT

Full Text Available The relevance of this work is determined, on the one hand, by tightening of the foreign political situation and its possible negative impact on the food security of the country, and, on the other hand, by the crisis of the domestic agricultural sector. These factors demand the development of new approaches to regional agroindustrial complex (AIC management. The aim is to develop a methodology for assessing the level of food self-sufficiency in main food areas of the Volgograd region. The author used the results of the statistical materials of AIC of the Volgograd region for 2016. The analytical methods included mathematical analysis and comparison. The main results are as follows. Based on the analysis of the current situation to ensure food security of Russia it was proved that at the present time it is necessary to develop effective indicators showing the level of self-sufficiency in basic food regions. It was also revealed that at the moment this indicator in the system of regional agrarian and industrial complex is not controlled. As a result of generalization of existing approaches the author’s method of rating the level of self-sufficiency of regions was offered. Its testing was carried out in several districts of the Volgograd region. The proposed authoring method of rating estimation of self-sufficiency in basic foodstuffs can be used in the regional agroindustrial complex management system at the federal and local levels. It can be used to rank areas in terms of their self-sufficiency in basic foodstuffs. This allows us to focus on the development of backward areas of agro-food and make appropriate management decisions. The final rating value - 0.759 obtained by the results of analysis of the situation in the Volgograd region means that the situation in matters of selfsufficiency in basic foodstuffs in general is good. However, we should aim at the maximum possible value of the rating - 1. In the application of the proposed

Chemistry Based on Renewable Raw Materials: Perspectives for a Sugar Cane-Based Biorefinery

Murillo Villela Filho

2011-01-01

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

Bacterial endophytes of the genus Herbaspirillum colonize sugar cane and can promote plant growth. The molecular mechanisms that mediate plant- H. seropedicae interaction are poorly understood. In this work, we used 2D-PAGE electrophoresis to identify H. seropedicae proteins differentially expressed at the log growth phase in the presence of sugar cane extract. The differentially expressed proteins were validated by RT qPCR. A total of 16 differential spots (1 exclusively expressed, 7 absent, 5 up- and 3 down-regulated) in the presence of 5% sugar cane extract were identified; thus the host extract is able to induce and repress specific genes of H. seropedicae. The differentially expressed proteins suggest that exposure to sugar cane extract induced metabolic changes and adaptations in H. seropedicae presumably in preparation to establish interaction with the plant.

DEMONSTRATION OF EQUIVALENCY OF CANE AND SOFTWOOD BASED CELOTEX FOR MODEL 9975 SHIPPING PACKAGES

International Nuclear Information System (INIS)

Watkins, R; Jason Varble, J

2008-01-01

Cane-based Celotex(trademark) has been used extensively in various Department of Energy (DOE) packages as a thermal insulator and impact absorber. Cane-based Celotex(trademark) fiberboard was only manufactured by Knight-Celotex Fiberboard at their Marrero Plant in Louisiana. However, Knight-Celotex Fiberboard shut down their Marrero Plant in early 2007 due to impacts from hurricane Katrina and other economic factors. Therefore, cane-based Celotex(trademark) fiberboard is no longer available for use in the manufacture of new shipping packages requiring the material as a component. Current consolidation plans for the DOE Complex require the procurement of several thousand new Model 9975 shipping packages requiring cane-based Celotex(trademark) fiberboard. Therefore, an alternative to cane-based Celotex(trademark) fiberboard is needed. Knight-Celotex currently manufactures Celotex(trademark) fiberboard from other cellulosic materials, such as hardwood and softwood. A review of the relevant literature has shown that softwood-based Celotex(trademark) meets all parameters important to the Model 9975 shipping package

Filgueiras, G.

1981-08-04

A flexible nonpolluting industrial scheme is described for converting sugar cane into fuel-grade ethanol, fertilizer, and electric power. The cleaned cane is treated in a diffuser to separate the juice, which is enzymically hydrolyze d to ethanol, and bagasse containing 65-85% moisture, which is mechanically ground with the rest of the cane plant (leaves and buds) and biochemically digested to provide liquid and solid fertilizers as well as a methane-containing gas, which is burned in a gas turbine to generate electricity. The vinasse from the ethanol fermentation is also cycled to the digestion step. The process conditions can be varied depending upon the desired product ratio; if fuel is preferred, each ton of cane (dry weight) can produce 135 L ethanol, 50 kW electric power, and 150 kg fertilizer; if electric energy is preferred, each ton can give 75 L ethanol, 115 kW power, and 220 kg fertilizer.

However, the low phosphorus availability in the soil becomes a limiting factor in the development of culture, mainly for ratoon cane. Thus, the objective of this study was to evaluate the performance of ratoon cane under different levels of phosphorus, applied in corrective phosphate and of the maintenance in the plant cane. The experiment was conducted in Alta Floresta (MT, end the experimental design was a randomized block with split plots, being four doses of corrective phosphate and five of maintenance. The corrective phosphating was carried out in the entire area with natural reactive phosphate Arad in the doses of 0, 90, 180 and 270 kg ha-1 of P2O5, and the maintenance done in the furrow with triple superphosphate, at rates of 0, 50, 100, 150 and 200 kg ha-1 of P2O5. The fertilization in plant cane promoted residual effect for cane ratoon, however, only the Arad phosphate promoted significant differences in green mass productivity, occurring linear increase for the tested doses.

Tasanee Thitakamol

2010-07-01

Full Text Available The research aimed to study the effect of distillery slop and chemical fertilizer on soil fertility, growth and yield of sugar cane. The field experiment was conducted on Mahasarakam soil series, using the K 88-92 variety of sugar cane. The results showed that distillery slop significantly increased some nutrients in soil, particularly potassium, magnesium, sulfur and chloride. The results also showed that application of distillery slop did not affect most of the physical properties of soil. Only the saturated hydraulic conductivity was significantly decreased under non-application of fertilizer. Under the application of distillery slop, chemical fertilizer had no significant effect on the yield and the juice quality of sugar cane for both crop years. However, under non-application of distillery slop in the first crop year, application of 21-0-0 and 20-20-0 fertilizer had a significant effect on cane yield. With the application of chemical fertilizer, distillery slop had an influence on the yield of sugar cane in both crop years while different doses of slop did not make any significant difference on cane yield. The average yields of the first crop year were 126.7, 195.6, 203.0 and 187.2 ton/hectare and those of the second crop year were 85.0, 150.0, 150.8 and 142.4 ton/hectare after the application of 0, 187.5, 375 and 562.5 m3/hectare, respectively. The results also showed that application of distillery slop did not have any significant effect on juice quality for both crop years. Investigation of slop trace under the ground surface indicated that application of distillery slop did not affect the quality of underground water as the deepest level of trace was only 50 centimeters.

The spread of cane toads (Rhinella marina: Bufonidae) has been devastating for native fauna in tropical Australia, but the toads' impact remains unstudied in temperate-zone Australia. We surveyed habitat characteristics and fauna in campgrounds along the central eastern coast of Australia, in eight sites that have been colonized by cane toads and another eight that have not. The presence of cane toads was associated with lower faunal abundance and species richness, and a difference in species composition. Populations of three species of large lizards (land mullets Bellatorias major, eastern water dragons Intellagama lesueurii, and lace monitors Varanus varius) and a snake (red-bellied blacksnake Pseudechis porphyriacus) were lower (by 84 to 100%) in areas with toads. The scarcity of scavenging lace monitors in toad-invaded areas translated into a 52% decrease in rates of carrion removal (based on camera traps at bait stations) and an increase (by 61%) in numbers of brush turkeys (Alectura lathami). The invasion of cane toads through temperate-zone Australia appears to have reduced populations of at least four anurophagous predators, facilitated other taxa, and decreased rates of scavenging. Our data identify a paradox: The impacts of cane toads are at least as devastating in southern Australia as in the tropics, yet we know far more about toad invasion in the sparsely populated wilderness areas of tropical Australia than in the densely populated southeastern seaboard.

To cope, both with the increasing demand for sugar and to win the global competition as well, government-owned sugar cane limited number xxi-xxii, has decided to enhance its productivity, among other things, by implementing ergonomics principles within their factories. In the execution, ergonomics application have been carried out since 1992, which resulted in safer, healthier, and more efficient working conditions and environment. Some of the improvements yielded economic gains through higher productivity via increased output, lower cost, faster processing, etc. Improvements related to cane transloading and unloading processes resulted in a higher amount of cane being transferred from the trucks to the lorries as well as from the lorries to the cane table. Fewer clinical visits, lower health care costs, more efficient inspection, and fewer fatigue complaints are also achieved by improvement steps, which increase the productivity as end results. With all those economic gains, full and long lasting management's concern and commitment could be created without a doubt.

Production of Microbial Transglutaminase on Media Made from Sugar Cane Molasses and Glycerol

Directory of Open Access Journals (Sweden)

Manuel Vázquez

Full Text Available Transglutaminase is an enzyme that catalyses an acyl transfer reaction between γ-carboxamide groups of glutaminyl residues and lysine residues in proteins. Due to this property, this enzyme is used for enhancing textural properties of protein-rich food. The transglutaminase used as food additive is obtained by microorganisms, mainly by Streptoverticillium ladakanum. On the other hand, sugar cane molasses is a viscous liquid rich in noncrystallized carbohydrates (saccharose, glucose and fructose. In this work, the feasibility of using sugar cane molasses as a carbon source for the production of microbial transglutaminase by Streptoverticillium ladakanum NRRL 3191 has been studied. Carbon sources including sugar cane molasses (60 g of total sugars per L, glycerol (60 g/L and their mixture in a ratio of 1:1 (30 g/L of each were evaluated. Time course of microbial growth, transglutaminase activity and carbon source consumption were determined every 24 h during 120 h of fermentations at three agitation speeds (200, 300 or 400 rpm. The results showed that with the increase in agitation speed, the biomass concentration increased up to 8.39 g/L in the medium containing sugar cane molasses alone or the mixture of molasses and glycerol. The highest transglutaminase activity was obtained at 400 rpm in the medium containing a mixture of molasses and glycerol, reaching 0.460 U/mL, while in the medium containing sugar cane molasses alone, the activity was 0.240 U/mL, and using glycerol alone it was 0.250 U/mL. These results show that sugar cane molasses is a suitable medium for transglutaminase production when it is combined with glycerol.

Full Text Available The basis for innovative development of the agroindustrial complex is the goals, principles and methods that determine the economic security of the region. The category of “economic security”is often identified with the sustainability, competitiveness and risk-free economy of agricultural and processing enterprises. Ensuring the economically safe functioning of all industries and spheres of regional agribusiness is impossible without interconnection with science and education. The most important principles necessary for the formation in the regional and national agribusinesses of a developed economically secure market of scientific, technical and innovative products for agroindustrial purposes are the following: providing the scientific and research sphere of the agro-industrial complex with highly qualified personnel; ensuring real freedom and independence in the activities of research institutions; the formation of a common interdependent economic space and interest; organization of specialized market structures in the field of research and innovation development; development and application within the regional agro-industrial complex of a scientifically grounded economic mechanism for regulating the functioning and stimulating the development of the market for scientific and technical innovation products. Purposeful development of the civilized market of scientific, technical and innovative products of agro-industrial design with its corresponding structures and organizational-economic mechanism is an objective necessity of functioning of economic security of the national economy. The interests of the economic and food security of the region and the state as a whole need to increase the financing of the agricultural sector and the processing industry to a level that will overcome the investment and innovation crisis caused by sanctions. To this end, we believe it is necessary to finance the innovative investment agrarian fund at the

Full Text Available This study involved the determination of the peroxide value (POV as a measure of the resistance of the oxidation of edible oil with grape vine cane additives to assess their antioxidation potential. The study demonstrated that grape extracts of canes could effectively inhibit the lipid oxidation of edible oils and that this ability varied significantly due to the different extraction solvents employed, as well as to the different varieties of canes used. Lipid oxidation of edible oils was significantly reduced under an accelerated storage condition of 70 ± 1 °C in the presence of Vitamin C (VC, which was chosen as a synergist of grape vine cane extract. A 4:1 ratio of Victoria Blanc-ethyl acetate fraction (EAF and VC led to a significant lowering of the peroxide value and indicated a better antioxidant effect. Thus, these results indicated that some varieties of grape vine cane extracts could be applied as natural antioxidants for elevation of the quality of edible oils in the food industry.

WHITE PAPER: DEMONSTRATION OF EQUIVALENCY OF CANE AND SOFTWOOD BASED CELOTEX FOR 9975 PACKAGING

International Nuclear Information System (INIS)

Varble, J

2007-01-01

Cane-based Celotex(trademark) has been used extensively in various DOE packages as a thermal insulator and impact absorber. Cane-based Celotex(trademark) for the 9975 was manufactured by Knight-Celotex Fiberboard at their Marrero Plant in Louisiana. However, Knight-Celotex Fiberboard shut down their Marrero Plant in early 2007 due to impacts from hurricane Katrina and other economic factors. Therefore, cane-based Celotex(trademark) is no longer available for use in the manufacture of new 9975 packages. Knight-Celotex Fiberboard has Celotex(trademark) manufacturing plants in Danville, VA and Sunbury, PA that use softwood and hardwood, respectively, as a raw material in the manufacturing of Celotex(trademark). The purpose of this White Paper is to demonstrate that softwood-based Celotex(trademark) from the Knight-Celotex Danville Plant has performance equivalent to cane-based Celotex(trademark) from the Knight-Celotex Marrero Plant for transportation in a 9975 package

Biogas systems for sisal and other agro-industrial residues

Most of the East-African agro-industries are generating very large quantities of organic residues from production and processing of different crops. In the East-African Region the most important of these crops are: Sisal, Sugar, Coffee, Cashew nuts and Pineapple. In other 3. world countries, Palm oil and Cassava (Tapioca starch) processing are main producers of organic waste products. Moreover, large quantities of organic residues are generated from other food processing activities like breweries, consumption of bananas etc. The following pages give examples of setups and system designs of anaerobic treatment systems for some of the residues mentioned above. When considering anaerobic treatment of sisal residues, which constitutes the main agro-industrial biomass resource in Tanzania, two major issues should be considered: Optimal reactor set-up and performance; And optionally, potential methods for pre-treatment of fibre fraction in order to increase the methane yield. The sisal liquid residues are degraded very fast and efficiently in UASB systems. At COD loading rates less than 11 kg COD/m{sup 3} x day, the reduction in organic matter is more than 90% and methane yields obtained are between 373 and 377 ml CH{sub 4}/g COD reduced. The treatment of sisal solid residues in CSTR systems has been examined both at mesophilic (37 deg. C) and thermophilic temperatures (55 deg. C.). (EG)

Annual and monthly-based emission inventories in northern, central and north-eastern provinces in Thailand, where agriculture and related agro-industries are very intensive, were estimated to evaluate the contribution of agricultural activity, including crop residue burning, forest fires and related agro-industries on air quality monitored in corresponding provinces. The monthly-based emission inventories of air pollutants, or, particulate matter (PM), NOx and SO 2 , for various agricultural crops were estimated based on information on the level of production of typical crops: rice, corn, sugarcane, cassava, soybeans and potatoes using emission factors and other parameters related to country-specific values taking into account crop type and the local residue burning period. The estimated monthly emission inventory was compared with air monitoring data obtained at monitoring stations operated by the Pollution Control Department, Thailand (PCD) for validating the estimated emission inventory. The agro-industry that has the greatest impact on the regions being evaluated, is the sugar processing industry, which uses sugarcane as a raw material and its residue as fuel for the boiler. The backward trajectory analysis of the air mass arriving at the PCD station was calculated to confirm this influence. For the provinces being evaluated which are located in the upper northern, lower northern and northeast in Thailand, agricultural activities and forest fires were shown to be closely correlated to the ambient PM concentration while their contribution to the production of gaseous pollutants is much less.

Full Text Available Sugarcane is known to absorb more Si than any other nutrient from the soil; therefore continuous cropping of the plant at the same soil would bring consequences of more Si and organic matter depletion. Silicon (Si is considered as a beneficial nutrient for sugarcane production while organic matter is well known as soil amendment. Field study was carried out to know the effect of organic and Si liquid fertilizer on growth, Si and N uptake, and yield of cane variety of PSBM 901. The study field was located at Kempleng village, Purwoasri, East Java and the study was done from May 2013 up to September 2014. Split plot design with three replicates was employed to arrange treatments. Organic matter types (no organic matter, Crotalaria juncea and manure were set as main plots while Si liquid fertilizer concentration (0, 15% Si and 30% S were arranged as sub plots. C juncea was planted at 15 days before planting of sugar cane, and after 35 days the C juncea were chopped and mixed into the soil. Manure was added one week before sugar cane was planted. Si liquid fertilizer was sprayed to the whole part of sugar cane plant at 30 and 50 days after sugar cane was planted. All treatments received basal fertilizer of 800 kg ZA/ha, 200 kg SP 36/ha and 300 kg KCl/ha. Results showed that interaction between organic matter and Si liquid fertilizer significantly affected on Si and N absorption, length of stem, yield and rendement of sugar cane. Addition of manure and followed by spraying of 30% Si liquid fertilizer gave the highest value of S and N absorption (869 g SiO2/plant and 720 g N/plant, cane yield (155.74 tons/ha and rendement (8.15%.

Full Text Available In order to strengthen the National System of Agricultural Science and Technology, the Ministry of Agriculture and Rural Development-MARD (within the "Transition of Agriculture" project launched a series of studies in 2006 aimed at denning Prospective Investigation-guidelines documentation for 20 productive chains. This initiative included the implementation of the second phase of the study by the second half of 2008, which involves the productive chain of sugar cane agro-industry focused on Panela due to its economic and social importance. In this context the Panela industry represents a sub-sector dedicated to the generation of products from sugar cane, positioning such products, right after coffee, as the second line of rural employment generation and occupies the fifth position in the country crops classification in terms of acreage (fields. This article presents the results of a study whose main purpose was to define prospective research guidelines for the productive chain by means of a conceptual and methodological perspective that involved the use of technological management tools such as performance analysis, benchmarking, technological monitoring, commercial market trends and foresight. This was achieved through a successful technology intelligence system, where four strategic areas for research and technological development were identified for the chain by grouping 11 technological needs that are to be addressed from 41 baselines linked to priority projects. These projects focus on improving the competitive position of the productive chain associated to sugar cane (particularly Panela agro-industry.

Full Text Available The Cane Corso Italiano belongs among the new dog breeds that were fully recognised by Federation Cynologique Internationale (FCI in 2007. For the first time, this study describes a median lifespan using the data of 232 dogs of the Cane Corso Italiano breed collected from kennels and individual owners from 25 countries. The median lifespan of the whole examined group is 9.29 years (IQR 6.98-11.12, IQR = Interquartile Range. This paper is the first to describe the possible relationship between median lifespan and hair colour within one breed. The longest living group is formed by black brindle coloured dogs, with a median of 10.30 years (IQR 8.33-13.00, and brindle coloured dogs, with a median of 10.13 years (IQR 7.12-11.25. The median lifespan of black brindle dogs exceeded the overall median lifespan of all dogs by 1.01 year and the median lifespan of other colour dogs by 2.21 years. Our results suggest a possible way for a prolongation of age at death of the Cane Corso Italiano breed using appropriate breeding. The median lifespan of male Cane Corso Italiano dogs is 9.25 years (IQR 6.97-11.00 and female Cane Corso Italiano dogs 9.33 years (IQR 7.00-11.31. The statistical analysis using the Independent Samples Student’s t test confirmed that the lifespan of female dogs did not exceed the median lifespan of male dogs (P>0.01.

During the cutting and loading operations, impurities, mainly soil, are added to sugar cane in amounts that can impair industrial processing due to excessive wear of metallic members and contamination of juice and bagasse. Mechanization of loading operation has showed a considerable enhancement of the impurity content, leading to the improvement of cane washing technology. Nevertheless, for a correct understanding of the problem and the process optimization, it is necessary and exact and fast quantification of these impurities as well as of its consequences. Nuclear techniques, in special neutron activation analysis, have been proved to be appropriate for estimating soil level in sugar cane, washing process efficiency and wearing of cases and moving parts.

2014-01-01

Full Text Available In this research we introduce a wearable sensory system for motion intention estimation and control of exoskeleton robot. The system comprises wearable inertial motion sensors and shoe-embedded force sensors. The system utilizes an instrumented cane as a part of the interface between the user and the robot. The cane reflects the motion of upper limbs, and is used in terms of human inter-limb synergies. The developed control system provides assisted motion in coherence with the motion of other unassisted limbs. The system utilizes the instrumented cane together with body worn sensors, and provides assistance for start, stop and continuous walking. We verified the function of the proposed method and the developed wearable system through gait trials on treadmill and on ground. The achievement contributes to finding an intuitive and feasible interface between human and robot through wearable gait sensors for practical use of assistive technology. It also contributes to the technology for cognitively assisted locomotion, which helps the locomotion of physically challenged people.

The future of sugar cane in China and India - Supply constraints and expansion potential

International Nuclear Information System (INIS)

Kostka, Genia; Polzin, Christine; Scharrer, Jenny

2009-01-01

The last decade has seen a surging demand for biofuels in the wake of increasing oil prices and rising environmental concerns. The most common biofuel is bio-ethanol accounting for more than 90% of total biofuel usage. It is increasingly produced from sugar cane making cane a strategic crop for biofuels. Given the growing demand for 'green' fuels, bio-ethanol production has been supported by energy policies in the past decade, which have consequently been accused of contributing to the global trend of rising food prices and thus jeopardising food security. However, while biofuel policies are an important driver, prices as much as food security will ultimately be determined by supply constraints of strategic crops. This paper hence investigates drivers of and constraints to sugar cane production in China and India and shows that supply side constraints vary significantly in the two countries. China and India both face serious limitations with regard to suitable available land for the further expansion of sugar cane production. Equally they are both faced with challenges to increasing yield output per hectare, albeit different ones. With regard to productivity, China achieved 2.7% annual yield growth since 1997, while India has seen yield decreases of -0.1% p.a. over the same period. The authors conclude that cane used as a feedstock to meet the rising energy demand will come at the expense of converting fertile land for non-food purposes.

Phenolic compounds and antioxidant activities of grape canes extracts from vineyards

Energy Technology Data Exchange (ETDEWEB)

Ju, Y.; Zhang, A.; Fang, Y.; Liu, M.; Zhao, X.; Wang, H.; Zhang, Z.

Grape canes are the main agro-wastes from vineyards. This work studied the antioxidant activities of the defatted methanolic extracts (ME) of canes from 11 genotypes: 5 Vitis vinifera widely known cultivars and 6 Chinese wild varieties from three species (V. amurensis, V. davidii, and V. pentagona) and the antioxidant activities of the ME’s chloroform fractions (CF), ethyl acetate fractions (EAF) and water fractions (WF). Among ME and its three fractions, EAF’s total phenolic contents (TPC) and total flavonoid contents (TFC) were the highest, at 586 mg/g of gallic acid equivalent and 320 mg/g of quercetin equivalent, respectively. The antioxidant power of the fractions/extracts was in the order EAF > ME > WF > CF, based on the DPPH radical-scavenging power and ferric-reducing antioxidant activity, while the order was EAF > CF > WF >ME based on the β-carotene-linoleic acid bleaching activity. Methanolic extracts demonstrated the strongest Fe2+-chelating activity. The antioxidant activities of the extracts/fractions generally correlated with the TPC and TFC in all assays, except with the Fe2+-chelating test. Grape canes from V. davidii had the highest TPC, TFC and antioxidant activities compared with those from other grape species. Catechin, epicatechin and trans-resveratrol were the predominant phenolic components of fractions/extracts. In light of these valuable bioactivities, grape canes from annual pruning practice considered as waste material have good commercial potential for utilization as a promising natural antioxidant in the food, pharmaceutical and cosmetic industries, given its low cost and availability in large amounts.

2012-03-01

Full Text Available Results are presented on the hot water prehydrolysis of sugar cane bagasse for obtaining ethanol by fermentation. The experimental study consisted of the determination of the effect of temperature and time of prehydrolysis on the extraction of hemicelluloses, with the objective of selecting the best operating conditions that lead to increased yield of extraction with a low formation of inhibitors. The study, carried out in a pilot plant scale rotational digester, using a 3² experimental design at temperatures of 150-190ºC and times of 60-90 min, showed that it is possible to perform the hot water prehydrolysis process between 180-190ºC in times of 60-82 min, yielding concentrations of xylose > 35 g/L, furfural < 2.5 g/L, phenols from soluble lignin < 1.5 g/L, and concentrations < 3.0 g/L of hemicelluloses in the cellolignin residue. These parameters of temperature and prehydrolysis time could be used for the study of the later hydrolysis and fermentation stages of ethanol production from sugar cane bagasse.

Liu, Hao Howe; Quiben, Myles; Holmes, Clayton; Connors, Michael; Salem, Yasser

To identify the differences in the limits of stability (LOS) between older rolling walker and single-tip-cane users. This was a matched paired t-test design with repeated measure. Eighteen older subjects were matched based on age, gender, and functional level. The subjects were assessed using the multidirectional reach test initially and 5-month later in four directions: forward, backward, leftward, and rightward. Initially, there were no differences between cane users and rolling walker users in the LOS in all directions. However, 5-month later, the cane users who held their canes in their right hand had significantly better stability in forward and rightward reach than the walker users (p walker users demonstrated significantly decreased functional reach in forward reach (p walker users in the forward direction and in the direction toward the side holding the cane. This study may provide guide for clinicians including nurses for selecting appropriate rehabilitative interventions for older adults using walkers and canes.

Tools and criteria for the Cost-Benefit analysis from the energy saving in bioclimatic designs (BD) are presented, for which, a reference project is established and the costs and benefits of energy saving in BD with base in that project are evaluated. A case study is presented taking as reference the traditional design of the air conditioning of a building and with this base the estimation of cost-benefit of the same building is made, but with passive systems. The tools used are those that allow to consider related resources such as time and money; in that sense, are used criteria such as: Present value (PV), Equivalent Annual Cost (EAC) and the Cost of the Conserved Energy (CCE). The costs related to the construction, maintenance and operation of the design are taken into account. The differences between the reference design and the BD, established from the application of these criteria, allow to evaluate the economic margin of the BD as far as operation and maintenance is concerned. Finally the CCE of the bioclimatic measures is evaluated as an initiative of energy saving and the present value is calculated of the energy saving in the entire useful life of a bioclimatic design.

"Candy cane" syndrome (a blind afferent Roux limb at the gastrojejunostomy) has been implicated as a cause of abdominal pain, nausea, and emesis after Roux-n-Y gastric bypass (RYGB) but remains poorly described. To report that "candy cane" syndrome is real and can be treated effectively with revisional bariatric surgery SETTING: All patients underwent "candy cane" resection at University Hospitals of Cleveland. All patients who underwent resection of the "candy cane" between January 2011 and July 2015 were included. All had preoperative workup to identify "candy cane" syndrome. Demographic data; pre-, peri-, and postoperative symptoms; data regarding hospitalization; and postoperative weight loss were assessed through retrospective chart review. Data were analyzed using Student's t test and χ 2 analysis where appropriate. Nineteen patients had resection of the "candy cane" (94% female, mean age 50±11 yr), within 3 to 11 years after initial RYGB. Primary presenting symptoms were epigastric abdominal pain (68%) and nausea/vomiting (32%), particularly with fibrous foods and meats. On upper gastrointestinal study and endoscopy, the afferent blind limb was the most direct outlet from the gastrojejunostomy. Only patients with these preoperative findings were deemed to have "candy cane" syndrome. Eighteen (94%) cases were completed laparoscopically. Length of the "candy cane" ranged from 3 to 22 cm. Median length of stay was 1 day. After resection, 18 (94%) patients had complete resolution of their symptoms (Psyndrome is a real phenomenon that can be managed safely with excellent outcomes with resection of the blind afferent limb. A thorough diagnostic workup is paramount to proper identification of this syndrome. Surgeons should minimize the size of the blind afferent loop left at the time of initial RYGB.

Full Text Available Formation of market relations in Russian economy generates an objective need to address a number of problems in the relationship between agroundustrial complex organizations in connection with privatization, liberalization of prices and imbalances in the existing inter-industry production and economic relations that negatively affect the results of their economic activities. Because of the flagrant violations of the replenishment process, a diverse range of connections and relationships between producers and processors was broken. The major direction of lifting agricultural economy in this situation is the development of cooperatives and agroindustrial integration. In addition, the formation of large integrated complexes demonstrates high efficiency and rapid development, which is the basis of agroindustrial sector in many developed countries. The increase of competition forces business entities to combine capabilities and mutually beneficial cooperation in the struggle for the strengthening of market positions. Thus, increasing the degree of integration in the agricultural sector helps to get out of the protracted crisis and move more quickly to the innovations.

Halim, Suharsono; Handafiah, Finna; Aprilliyani, Ria; Udhiarto, Arief

2018-02-01

The Indonesian Ministry of Social Affairs, in July 2012, informed that the number of blind in Indonesia has been the largest among to the people with other disabilities. The most common tools utilized to help the blind was a conventional cane which has limited features and therefore it was difficult to be used as a mobilization tools. Moreover, the conventional cane cannot assist them or their family when the blind gets lost. In this research, we designed and implemented an electronic white cane with the concept of radar and global positioning system (GPS). The purpose of this research was to design and develop an electronic white cane which can enhance the mobility of the blind without distance coverage limitation. Utilizing ultrasonic sensors as a distance measurement and a servo motor as an actuator, the produced radar system is able to map an area with maximum distance and coverage angle of 5 meters and 180° respectively. The blind senses the obstacle around them from the vibration generated by five vibration motors. The vibration becomes more intense when the obstacle is detected closer. In addition, we implemented a GPS to monitor the blind's position and allow their family to find them easily when the blind need a help. Based on the tests performed, we have successfully developed an electronic white cane that can be a solution to improve the blind's mobility.

First steps in translating human cognitive processes of cane pruning grapevines into AI rules for automated robotic pruning

Directory of Open Access Journals (Sweden)

Saxton Valerie

2014-01-01

Full Text Available Cane pruning of grapevines is a skilled task for which, internationally, there is a dire shortage of human pruners. As part of a larger project developing an automated robotic pruner, we have used artificial intelligence (AI algorithms to create an expert system for selecting new canes and cutting off unwanted canes. A domain and ontology has been created for AI, which reflects the expertise of expert human pruners. The first step in the creation of an expert system was to generate virtual vines, which were then ‘pruned’ by human pruners and also by the expert system in its infancy. Here we examined the decisions of 12 human pruners, for consistency of decision, on 60 virtual vines. 96.7% of the 12 pruners agreed on at least one cane choice after which there was diminishing agreement on which further canes to select for laying. Our results indicate that techniques developed in computational intelligence can be used to co-ordinate and synthesise the expertise of human pruners into a best practice format. This paper describes first steps in this knowledge elicitation process, and discusses the fit between cane pruning expertise and the expertise that can be elicited using AI based expert system techniques.

Every one involved with the conservation and efficient use of electric energy, has listened in reiterative occasions to the causes that changed the conventional mentality at the beginning of the seventies. Nevertheless, there are many persons that still ignore that by using the energy rationally, their costs are significantly reduced, their comfort is enhanced and the environmental problems are minimized. Specifically, in the domestic sector, from the figures reported by the Comision Federal de Electricidad (CFE) in 1996, the electric energy sold was 28,410 Gwh, that is, 23.4% of the total consumption (121,579 Gwh). Table 1 presents the average by tariff in the national domestic sector, which shows that 20% of the electricity consumed was required for environmental conditioning (air conditioning, evaporative coolers and electric fans). The above figures quantitatively show that there is a strong impact in the consumption of electric energy due to weather conditions. For this reason, currently the Comision Nacional de Ahorro de Energia (CONAE) and the Fideicomiso para el Ahorro de Energia (FIDE) are promoting standards and projects to propitiate the rationalization in the use of energy, besides of achieving the improvement of thermal comfort conditions. One more case would be the Fideicomiso para el Aislamiento Termico de la Vivienda en Mexicali (FIPATERM), which promotes the financing of saving measures and efficient energy use in cities with extreme climate. This paper describes the strategy that was followed by the Instituto de Investigaciones Electricas (IIE), for the development of the human and material infrastructure, that has allowed the sustainment of several projects in the saving and efficient use of energy in CFE, CONAE, FIDE, FIPATERM and the Lawrence Berkeley National Laboratory (LBNL), concretely in relationship with the thermal analysis of dwellings.

To test the hypothesis that use of a cane in the nondominant hand during challenging balance tasks would significantly decrease loss of balance in patients with peripheral neuropathy while transferring from bipedal to unipedal stance on an unsteady surface. Nonrandomized control study. Tertiary-care institution. Eight consecutive patients with peripheral neuropathy (PN) and eight age- and gender-matched controls (C) with a mean (SD) age of 65 (8.2) years. Subjects were asked to transfer their weight onto their right foot, despite a rapid +/- 2 degrees or +/- 4 degrees frontal plane tilt of the support surface at 70% of weight transfer, and balance unipedally for at least 3 seconds. The efficacy of their weight transfer was evaluated over 112 consecutive randomized and blocked trials by calculating loss of balance as failure rates (%FR) with and without visual feedback, and with and without use of a cane in the nondominant (left) hand. Results were analyzed using a 2 x 2 x 2 x 2 x 2 repeated-measures analysis of variance (rm-ANOVA) and post hoc t tests. The rm-ANOVA showed that the FR of the PN subjects (47.6% [18.1%]) was significantly higher than C (29.2% [15.2%], p = .036). Removing visual feedback, simulating the dark of night, increased the FR fourfold (p = .000). Use of a cane in the contralateral nondominant hand significantly reduced the FR (p = .000), particularly in the PN group (cane x disease interaction: p = .055). Post hoc t tests showed that with or without visual feedback, the cane reduced the FR of the PN group fourfold and enabled them to perform more reliably than matched controls not using a cane (p = .011). An inversion perturbation resulted in a higher FR than an eversion perturbation (p = .007). The PN group employed larger mean peak cane forces (21.9% BW) than C (13.6% BW) in restoring their balance (p = .000). Use of a cane by PN patients significantly reduced their risk of losing balance on unstable surfaces, especially under low

2015-04-01

Full Text Available Grape cane, leaves and grape marc are waste products from viticulture, which can be used to obtain secondary stilbene derivatives with high antioxidant value. The presented work compares several extraction methods: maceration at laboratory temperature, extraction at elevated temperature, fluidized-bed extraction, Soxhlet extraction, microwave-assisted extraction, and accelerated solvent extraction. To obtain trans-resveratrol, trans-ε-viniferin and r2-viniferin from grape cane of the V. vinifera variety Cabernet Moravia, various conditions were studied: different solvents, using powdered versus cut cane material, different extraction times, and one-step or multiple extractions. The largest concentrations found were 6030 ± 680 µg/g dry weight (d.w. for trans-resveratrol, 2260 ± 90 µg/g d.w. for trans-ε-viniferin, and 510 ± 40 µg/g d.w. for r2-viniferin. The highest amounts of stilbenes (8500 ± 1100 µg/g d.w. were obtained using accelerated solvent extraction in methanol.

Full Text Available The objective of this study was to evaluate the effects of harvesting methods on the macrofauna, a known indicator of soil quality that detects changes in the system and indicates management alternatives. The experimental design was randomized blocks with six replications, with each block consisting of four parcels that corresponded to treatments green cane (CC, burnt cane (CQ, green cane – burnt cane (CC-Q and burnt cane – green cane (CQ-C. Samples were collected in February and July 2010. The animals were divided into major taxonomic groups and accounted. Were evaluated ecological indexes (Shannon, Pielou and richness and average total density of individuals and groups. Data were analyzed by the nonparametric statistical tools by Friedman or Signal test at 5%. To check relationships between soil fauna and environmental variables, was used a multivariate conditional ordination method, the redundancy analysis (RDA. The index richness was more efficient than the total average density to evaluate the influence of cane harvesting systems, with the highest values related to areas harvested without burning. Further, the occurrence of key groups in the areas harvested without burning configures the establishment of a trophic web. There was dominance of the social group Formicidae in all treatments

To characterize nonfatal, unintentional, fall-related injuries associated with walkers and canes in older adults. Surveillance data of injuries treated in hospital emergency departments (EDs), January 1, 2001, to December 31, 2006. The National Electronic Injury Surveillance System All Injury Program, which collects data from a nationally representative stratified probability sample of 66 U.S. hospital EDs. People aged 65 and older treated in EDs for 3,932 nonfatal unintentional fall injuries and whose records indicated that a cane or a walker was involved in the fall. Sex, age, whether the fall involved a cane or walker, primary diagnosis, part of the body injured, disposition, and location and circumstances of the fall. An estimated 47,312 older adult fall injuries associated with walking aids were treated annually in U.S. EDs: 87.3% with walkers, 12.3% with canes, and 0.4% with both. Walkers were associated with seven times as many injuries as canes. Women's injury rates exceeded those for men (rate ratios=2.6 for walkers, 1.4 for canes.) The most prevalent injuries were fractures and contusions or abrasions. Approximately one-third of subjects were hospitalized for their injuries. Injuries and hospital admissions for falls associated with walking aids were frequent in this highly vulnerable population. The results suggest that more research is needed to improve the design of walking aids. More information also is needed about the circumstances preceding falls, both to better understand the contributing fall risk factors and to develop specific and effective fall prevention strategies.

The present work looks for integrating the actions of energy saving that can be applied in educative institutions, not concerning the level or size of the same ones. The actions go from questions of making aware the student population until those involved in the change in the operation, migration and implementation of technology. Without overlooking the formative aspect that the educative institutions have and the social commitment of these last ones. It is important that the saving measures have as mission to achieve a culture focussed to make efficient use of the resources, of energy as well as material. This culture must be born from the classrooms and must transform the way to be and act of the student community that will permeate itself with the society. Let us remember that actions are worth more than words, so the educative institutions must preach with the example. [Spanish] El presente trabajo busca integrar las acciones de ahorro de energia que pueden ser aplicadas en instituciones educativas, no importando el nivel o tamano de las mismas. Las acciones van desde cuestiones de concienciar a la poblacion estudiantil hasta las que involucran el cambio en la operacion, migracion e implementacion de tecnologia. Sin perder de vista el aspecto formativo que tienen las instituciones educativas y el compromiso social de estas ultimas. Es importante que las medidas de ahorro tengan como mision lograr una cultura enfocada a hacer uso eficiente de los recursos, tanto energeticos como materiales. Dicha cultura debe nacer desde las aulas y debe transformar la manera de ser y actuar, de la comunidad estudiantil que se permeara con la sociedad. Recordemos que las acciones valen mas que las palabras, asi que las instituciones educativas deben predicar con el ejemplo.

In the present work, selected agroindustrial solid residues from Brazil - biosolids from meat processing wastewater treatment and mixture of sawdust with these biosolids; residues from apple and orange juice industries; sugarcane bagasse; açaí kernels (Euterpe oleracea) and rice husk - were characterised as solid fuels and an evaluation of their properties, including proximate and ultimate composition, energy content, thermal behaviour, composition and fusibility of the ashes was performed. The lower heating value of the biomasses ranged from 14.31 MJkg(-1) to 29.14 MJkg(-1), on a dry and ash free basis (daf), all presenting high volatile matter content, varying between 70.57 wt.% and 85.36 wt.% (daf) what improves the thermochemical conversion of the solids. The fouling and slagging tendency of the ashes was predicted based on the fuel ash composition and on the ash fusibility correlations proposed in the literature, which is important to the project and operation of biomass conversion systems. The potential for application of the Brazilian agroindustrial solid residues studied as alternative energy sources in thermochemical processes has been identified, especially concerning direct combustion for steam generation.

The accelerated growth of the population brings with it an increase in the generation of agro-industrial effluents. The inadequate discharge of these effluents significantly affects the quality of water resources. In this way, it becomes important to invest in treatment processes for agro-industrial effluents, particularly low-cost ones. In this context, the present study includes the design and construction of an UASB reactor and optimization of the anaerobic digestion treatment of the raw effluent from sweet chestnut production in the agro-industrial company Sortegel. The efficiency of the system was evaluated through the determination / monitoring of oxygen chemical oxygen demand (COD), biochemical oxygen demand (BOD5), total suspended solids (TSS), biogas production rate and quality (% methane). The reactor was fed for 25 weeks and operated under mesophilic conditions (temperature 30-40 °C). Different values were tested for the hydraulic retention time (HRT) and volumetric flow rate (VF): 0.66 days (VF=1509 L.m-3.d-1); 1.33 days (VF=755 L.m-3.d-1); 2.41 d days (VF=415 L.m-3.d-1). The average COD removal efficiency reached values of 69%, 82% and 75%, respectively, and simultaneously the associated BOD5 removal efficiency was 84%, 91% and 70%. As regards TSS, removal values were 78%, 94% and 63%. In addition, high methane production rates were obtained, between 2500 and 4800 L CH4.kg-1 COD removed d-1. For all the hydraulic retention times tested, high concentrations of methane in the biogas were recorded: 66-75%, 70% and 75% for HRT of 0.66, 1.33 and 2.41 days, respectively.

Examine patterns of cane and walker use as related to falls and fall injuries. Among people who fall at home, most do not have an assistive device with them when they fall. Nonusers who fall sustain more severe injuries. This was a cross-sectional study using a self-administered written survey completed by 262 people aged 60 and older who were community dwelling, cognitively intact, and current cane/walker users with a history of falls. They were recruited through clinical practice sites, churches, and senior housing in central Michigan. Outcomes of interest included patterns of device use, reasons for nonuse, device use at time of fall, and fall-related injuries. Seventy-five percent of respondents who fell were not using their device at the time of fall despite stating that canes help prevent falls. Reasons for nonuse included believing it was not needed, forgetfulness, the device made them feel old, and inaccessibility. Perceived risk was not high enough to engage in self-protective behavior. However, nonuse led to a significantly higher proportion of falls resulting in surgery than among device users. Among respondents requiring surgery, 100% were nonusers. Most respondents never received a home safety evaluation (68%) and only 50% received training on proper device use. Providers must place increased emphasis on the importance of cane/walker use for injury prevention through patient education to promote personal relevance, proper fitting, and training. New strategies are needed to improve device acceptability and accessibility. © The Author 2015. Published by Oxford University Press on behalf of The Gerontological Society of America.

This study focuses on the technical viability evaluation of the fast pyrolysis of sugar cane straw for its energy use. By means of this thermochemical process, the sugar cane straw is converted into bio-fuels (biochar, bio-oil) and non-condensable gases. The bio-fuels obtained could be used as fuel or as raw material in the chemical industry. The fast pyrolysis of sugar cane straw has been developed in a fluidized bed reactor. In order to improve this process to obtain high bio-oil yield, the influence of the operational conditions (equivalence ratio and temperature) on the product yields and on their characteristics was evaluated. The product yields of bio-oil and char were up to 35.5 wt.% and 48.2 wt.% respectively. The maximum bio-oil yield was achieved at temperature and equivalence ratio conditions of 470 °C and 0.14. The bio-oil obtained has low oxygen content (38.48 wt.% dry basis), very low water content, and a lower heating value of 22.95 MJ/kg. The gas chromatographic analyses allowed the identification of oxygenated compounds and heterocyclic aromatic hydrocarbons. The bio-oil pH ranged between 3.14 and 3.57 due to the presence of acid organic compounds. The char obtained has a high fixed carbon and volatile matter content. Its HHV value is 13.54 MJ/kg. -- Highlights: • Pyrolysis of sugar cane straw was studied in a fluidized bed reactor. • The product yields were evaluated. • The composition of the liquid and solid products obtained was analyzed. • This is an environmentally friendly use for this waste

Full chain energy analysis of fuel ethanol from cane molasses in Thailand

Energy Technology Data Exchange (ETDEWEB)

Nguyen, Thu Lan T.; Gheewala, Shabbir H.; Garivait, Savitri [The Joint Graduate School of Energy and Environment, King Mongkut' s University of Technology Thonburi, Bangkok (Thailand)

2008-08-15

An analysis of energy performance and supply potential was performed to evaluate molasses utilization for fuel ethanol in Thailand. The Thai government recently has set up a production target of 1.925 million litres a day of sugar-based ethanol. The molasses-based ethanol (MoE) system involves three main segments: sugar cane cultivation, molasses generation, and ethanol conversion. Negative net energy value found for MoE is a consequence of not utilizing system co-products (e.g. stillage and cane trash) for energy. Taking into account only fossil fuel or petroleum inputs in the production cycle, the energy analysis provides results in favour of ethanol. A positive net energy of 5.95 MJ/L which corresponds to 39% energy gain shows that MoE is efficient as far as its potential to replace fossil fuels is concerned. Another encouraging result is that each MJ of petroleum inputs can produce 6.12 MJ of ethanol fuel. Regarding supply potential, if only the surplus molasses is utilized for ethanol, a shift of 8-10% sugar cane produce to fuel ethanol from its current use in sugar industry could be a probable solution.

2016-01-01

Child maltreatment is a worldwide phenomenon with far-reaching negative consequences, and physical abuse is its most visible and widely reported form of maltreatment. There is a fine line between nonabusive physical punishment and physical child abuse, and where this line is drawn is often influenced by prevailing cultural practices and child-rearing beliefs. This article focus on Singapore-a modern Asian society that remains rooted in traditional attitudes and practices-as a case study in exploring the boundaries. In particular, the local practice of caning (hitting with a rattan cane) as a disciplinary measure for children, the ambiguity of the law on the issue of physical abuse, and the influence of judicial caning on the acceptability of this common practice are examined. Finally, the possible means of safeguarding children and discouraging the use of physical punishment in the home are discussed.

To assess the feasibility, reliability, and construct validity of the Camberwell Assessment of Need for the Elderly (CANE) in identifying needs among community-dwelling older adults in South Lebanon with a view towards expanding ageing research in the country. A cross-sectional study was undertaken with 322 individuals, using the CANE, the EQ5d and a socio-demographic questionnaire. Reliability was determined through measuring internal consistency of the CANE. Construct validity was performed through examining CANE inter-item correlations, and comparing correlations with the EQ5d and socio-demographic indicators. A factor analysis was conducted using varimax orthogonal rotation. Cronbach alpha was 0.71. For construct validity, correlations were highest in items measuring needs in looking after the house and food (r = 0.557); company and intimate relationships (r = 0.572); and medication and written/verbal information (r = 0.586). Moderate correlations were found with EQ5d items assessing the same measure, including: EQ5d 'problems taking care of self' and CANE self-care (r = 0.578) and daytime activities (r = 0.523); EQ5d 'problems performing usual activities' and CANE daytime activities (r = 0.553), self-care (r = 0.511) and mobility (r = 0.500); and EQ5d 'problems while walking' and CANE mobility/falls (r = 0.509). Corresponding items of the CANE and EQ-5d were significantly correlated with similar socio-demographic variables. The factor analysis supported results obtained in the CANE inter-item correlations. The Arabic version of the CANE appears acceptable in assessing needs of older adults in South Lebanon. Given that the CANE is an interesting tool that promotes the integration of older persons' perspectives for appropriate interventions, further research is recommended to establish its validity and applicability in other communities in Lebanon and the region.

Forest Fragments Surrounded by Sugar Cane Are More Inhospitable to Terrestrial Amphibian Abundance Than Fragments Surrounded by Pasture

Directory of Open Access Journals (Sweden)

Paula Eveline Ribeiro D’Anunciação

2013-01-01

Full Text Available In recent years, there has been increasing interest in matrix-type influence on forest fragments. Terrestrial amphibians are good bioindicators for this kind of research because of low vagility and high philopatry. This study compared richness, abundance, and species composition of terrestrial amphibians through pitfall traps in two sets of semideciduous seasonal forest fragments in southeastern Brazil, according to the predominant surrounding matrix (sugar cane and pasture. There were no differences in richness, but fragments surrounded by sugar cane had the lowest abundance of amphibians, whereas fragments surrounded by pastures had greater abundance. The most abundant species, Rhinella ornata, showed no biometric differences between fragment groups but like many other amphibians sampled showed very low numbers of individuals in fragments dominated by sugar cane fields. Our data indicate that the sugar cane matrix negatively influences the community of amphibians present in fragments surrounded by this type of land use.

Environmental issues have supported the interest in renewable sources and agroindustrial residues became a significant resource for the production of new materials. The present work presents the use of agroindustrial residues to obtain bacterial cellulose (BC) for further elaboration of nanocomposites with hydroxyapatite (HA). The production of BC membranes occurred in Hestrin & Schramm medium, cashew juice and sisal liquid waste cultivated under static conditions. After the incubation period, the BC membranes were purified and nanocomposites prepared by successive immersion of the purified membranes in solutions of Calcium Chloride (CaCl_2), and Sodium Phosphate (Na_2HPO_4), followed by drying and subsequent characterization. The materials obtained were characterized by Thermogravimetric Analysis (TGA) and X-ray Diffraction (XRD). Additionally, in vitro tests were performed for nanocomposites. The results showed the production of cellulose from the three substrates studied, without the need for further supplementation or pH change. In all characterizations, structure and typical behavior of bacterial cellulose were found. The composites showed bioactivity and the adsorption capacity of proteins, which lead to potential biocompatibility of these materials. (author)

Taddeo, Raffaele; Honkanen, Mari; Kolppo, Kari; Lepistö, Raghida

2018-04-15

Improving environmental protection and finding sustainable and renewable resources of nutrients are core issues in circular bioeconomy. Thus, this study evaluated the efficiency of recovering struvite, MgNH 4 PO 4 ·6H 2 O, from different agro-industrial wastewaters (four highly loaded reject waters of anaerobically co-digested agro-industrial waste and a raw swine slurry) and assessed the quality of recovered struvite crystals and their reusability as fertilizer. The efficiency of crystallization (E c 40-80%) and amount of struvite in the precipitate (P p 55-94%) highly varied due to the characteristics of influent wastewaters, particularly to the content of competing elements, such as alkaline and heavy metals and total solids (TS). In particular, E c (94, 75, 61%) and P p (76, 66, 48%) decreased at increasing TS (0.57, 0.73, 0.99%), demonstrating the hindering effect of solid content on struvite recovery and quality. According to X-ray diffraction analysis, the structure of all isolated samples corresponded to crystalline, orthorhombic struvite, which exhibited high purity (32-48 g/kg d N, 114-132 g/kg d P, and 99-116 g/kg d Mg) containing only a few foreign elements, whose amount depended on the characteristics of the influent wastewater. All struvite contained other plant macronutrients (K, Ca) and many micronutrients (Fe, Na, Cu, Mn, Co, Zn) that further enhance its agronomic value. Therefore, this study showed that struvite can be successfully recovered from a wide range of highly loaded agroindustrial wastewaters, and that the quality of the recovered struvite could be suitable for reuse in agriculture.

Pene, C.B.G.

1995-01-01

A field study on sugar cane (Saccharum officinarum L.) yield response to deficit irrigation during both tillering and stem elongation stages, in order to increase crop water use efficiency, was carried out at Institut des Savanes (IDESSA) experimental station of Ferkessedougou, in Northern Ivory Coast. This cane crop tested was Co 449, an early - maturing genotype of indian origin. This experiment has been conducted for three consecutive years as virgin crop ( from November, 1991 to December 1992 ), first ratoon crop ( from December 1992 to January 1994 ) and as second ratoon crop ( from January 1994 to January 1995 ). The experimental design was a randomized complete block with 10 irrigation treatments in 4 replicates of 54 m sup2 sized plots. Water was applied through an improved furrow irrigation system. Crop water consumption was estimated using the water balance approach based on neutron probe and tensiometer measurements. This field water balance method required the determination of soil hydraulic conductivity as a function of water content and the neutron calibration curve. Data presented are related to the two ratoon crops for which field water balance measurements were investigated. It has been shown in the study that sugar cane growth and yield decline due to water deficit is significantly high during stem elongation as compared to tillering. As a result, the sugar cane tested was much more sensitive to water stress at stem elongation than at tillering. Therefore, deficit irrigation practice as to increase crop water use efficiency might be recommended at tillering rather than stem elongation. The water management strategy to be suggested here may consist of omitting irrigation during tillering ( assuming that the crop is successfully established ), for the benefit of stem elongation. As far as stem elongation is concerned, a moderate water deficit of about 25% with respect to the full irrigation regime appears to increase crop water use efficiency.6 figs

A pesquisa foi realizada no município de Morro Agudo, SP, de julho de 1995 a julho de 1997. A variedade cultivada foi a SP 70 -1143. Utilizaram-se como indicadores de crescimento os seguintes índices biométricos: número de perfilhos, número de folhas, matéria seca de colmos e de folhas, IAF e avaliou-se a influência das temperaturas e das umidades do ar, do solo e das folhas. Adotou-se regressão polinomial e regressão não-linear para se adaptar os dados às curvas de crescimento. O crescimento no primeiro ciclo foi semelhante para cana crua e cana queimada. No início do segundo ciclo ocorreu maior crescimento em cana crua, enquanto que no final, foi maior em cana queimada. O perfilhamento da cana crua não apresentou diferenças significativas que confirmem a influência negativa da palha na rebrota. Os fatores climatológicos, isoladamente, não provocaram mudanças nos ciclos de crescimento de maneira que se identificasse uma tendência geral. As diferenças expressas na curva de crescimento do 1º para o 2º ano são devidas aos fatores climatológicos, tanto para cana crua como para cana queimada.This work had as objectives: 1. to compare the shoot growth between green cane, mechanically harvested and burned cane, harvested manually; 2. to evaluate the influence of the weather on the two conditions of growth and 3. to analyze the growth of green cane and cane burned in the 1st and 2nd years of second ratoon cane crop, by means of adapted curves.

Sugar cane bagasse is waste from the sugar and ethanol industry and is primarily intended for burning in boilers to generate energy. As waste from the cogeneration of energy, sugar cane bagasse ashes (SCBA) are produced with no honorable destination. This paper studies the use of SCBA to partially replace Portland cement in producing cementitious composites. The ashes were processed by reburning and grinding, and after processing were characterized by a scanning electron microscope, x-ray diffraction, laser granulometry, and x-ray fluorescence spectrometry. After characterization, cement compounds were fashioned, replacing 0, 10, 20 and 30% of the cement with SCBA. The composites were mechanically evaluated by means of compression strength tests, tensile strength tests by bending. The results proved significant, indicating the possible use of SCBA when added to the cement on manufacture. (author)

Full Text Available Knowledge Management (KM and supply chain is a new approach used by many companies to create value, increase organizational effectivity and productivity, and competitiveness. However, this concept is still rarely used in agroindustry. The integration of KM and supply chain is very important. A supply chain which applies knowledge managemen system in all the chains will get the final value larger than the total values of all chains, and thus improve competitiveness f the product. The application of KM is initiated by collecting information from supply chain system which were then analysed and shared with all of the components of all chains to support decision making process. A key of success in the implementation of KM is knowledge sharing among components within the system. Another important factor is leadership to support the implementation of KM and colaboration with other parties

The common use of phosphate fertilizers NPK and amendments in sugar cane crops in Brazilian agriculture may increase the 226 Ra, 232 Th and 40 K activity concentrations in soils and their availability for plants and human food chain. Thus, the main aim of this study was to evaluate the distribution of 226 Ra, 232 Th and 40 K in soils and sugar cane crops in the Corumbatai river basin, Sao Paulo State, Brazil. The gamma spectrometry was utilized to measure the 226 Ra, 232 Th and 40 K activity concentration in all samples. The soil-to-sugar cane transfer factors (TF) were quantified using the ratio between the radionuclide activity concentration in sugar cane and its activity concentration in soil. The results show that, although radionuclides incorporated in phosphate fertilizers and amendments are annually added in the sugar cane crops, if utilized in accordance with the recommended rates, their use does not lead to hazards levels in soils. The soil-to-sugar cane transfer of radionuclides occurred in the following order 40 K> 226 Ra> 232 Th. Therefore, under these conditions, radionuclides intake through consumption of sugar is not hazardous to human health.

The feeds available for ruminants in developing countries are either agro-industrial by-products or specially grown forage crops. Many of these feeds are low in protein and require supplementation with non-protein N (NPN) to maintain efficient rumen function and digestibility. The principles for utilizing high energy, low protein feeds by ruminants are discussed in relation to the supply of NPN, the establishment of efficient rumen function, maximizing feed intake by means of supplements, and increasing total energy and protein intake by using supplements which bypass the rumen. To illustrate it the application of these principles to feeding systems based on molasses, chopped whole sugar cane and derinded sugar cane is discussed. The implications of the principles in increasing the feeding value of straw are also discussed. (author)

Full Text Available The rate of decomposition of sugar cane leaves mixed with an organic fertilizer compost type was evaluated, using a finite accelerator (molasses and an infinity accelerator (effective microorganisms. The trial was conducted in the greenhouse facilities of the National University of Colombia in Palmira. The results showed that molasses is a decomposition accelerator of the wastes of sugar cane leaf, since it shows a marked influence on the initial decomposition rate of the waste, but once the carbohydrates that constitute it are consumed, the rate of decomposition decreases significantly. Then the potential is evident on the waste of sugar cane leaf elements for the maintenance and/or biophysical capital improvement in the productive system of the sugar cane, as the result of their high photosynthetic efficiency.

Egea, Francisco J; Torrente, Roberto G; Aguilar, Alfredo

2018-01-25

In the last ten years, bioeconomy strategies and policy-related bioeconomy initiatives have been developed all over the world. Some of them are currently in the process of translation into specific actions. In most cases, the approaches followed have been top-down policy-related initiatives, triggered by the public sector originating a dynamic which can bring together different bioeconomy stakeholders i.e. industry, academia, financial operators and farmers. This article describes a bottom-up situation with unique bioeconomy-related features that deserve specific attention. Over the last 40 years, Almería, in the south east of Spain, has developed one of the most efficient agro-industrial complexes in the world, evolving from a traditional and subsistence agriculture, to becoming the major vegetable exporter in the European Union (EU). This growth set aside issues such as sustainability, long-term perspectives on water resources or agricultural waste. However, societal concerns about a circular economy, as well as policy initiatives in the EU and in Spain on bioeconomy are changing the situation towards an integrated, efficient and sustainable bioeconomy system. Currently, the production chain demands innovations related to the use of biomass as source of bioproducts and bioenergy in order to remain competitive. Some positive aspects are the relatively small size of the agro-industrial area, making transport and communications rapid and easy, and the existence of strong and dedicated academic and financial institutions. This article outlines the current efforts and initiatives to couple the existing successful agro-industrial complex with that of a fully sustainable bioeconomy model. Copyright © 2017 Elsevier B.V.

1993-12-31

The use of biomass as primary fuel for power and steam production using modern conversion technology such as the Biomass Integrated Gas Turbine/Combined Cycle (BIG/CC) has both technical and commercial potential. Brazil is implementing a BIG/CC Demonstration Plant to burn wood from eucalyptus short rotation forest and to test sugar cane bagasse as feedstock. The purpose of this project is to demonstrate the commercial viability of using biomass as a feedstock for power generation, its suitability for applications in developing countries, and the possibilities it offers for commercial activities in regions which currently have a low level of economic activities. The purpose of this paper is to show the potential applicability of this technology in the sugar cane industries of Developing Countries such as Brazil. The same quantity of sugar cane already processed in each sugar mill can produce sizable quantities of electric power at competitive costs, in addition to the traditional products -- sugar and/or ethanol, which will cause an economical impact, duplicating the revenue of these industries. The application of the BIG/CC technology in the Sugar Cane Industry may lead to the following scenario in developing countries: (1) power shall be produced at very competitive prices by specialized private firms associated with sugar mills; (2) plant sizes will be smaller -- 15 to 100 MW -- when based on biomass, a compared to large fossil fuel plants now prevailing; (3) ethanol and sugar production costs will be reduced due to more efficient and economical processes and due to the additional revenue from power production; (4) becoming more competitive with gasoline, ethanol production tends to increase, which will influence the automobile industry and improve the quality of life in big cities.

Our study tested the identity of Myxidium spp. within native frogs and the invasive Cane toad (brought to Australia in 1935, via Hawaii to resolve the question whether the Cane toad introduced them to Australia. We showed that the Australian brain and liver Myxidium spp. differed 9%, 7%, 34% and 37% at the small subunit rDNA, large subunit rDNA, internal transcribed spacers 1 and 2, but were distinct from Myxidium cf. immersum from Cane toads in Brazil. Plotting minimum within-group distance against maximum intra-group distance confirmed their independent evolutionary trajectory. Transmission electron microscopy revealed that the brain stages localize inside axons. Myxospores were morphologically indistinguishable, therefore genetic characterisation was necessary to recognise these cryptic species. It is unlikely that the Cane toad brought the myxosporean parasites to Australia, because the parasites were not found in 261 Hawaiian Cane toads. Instead, these data support the enemy-release hypothesis predicting that not all parasites are translocated with their hosts and suggest that the Cane toad may have played an important spill-back role in their emergence and facilitated their dissemination. This work emphasizes the importance of accurate species identification of pathogens relevant to wildlife management and disease control. In our case it is paving the road for the spill-back role of the Cane toad and the parasite emergence.

Bortoletto, Aline M; Alcarde, André R

2013-08-15

The profile of volatile compounds and aging markers in sugar cane spirits aged for 36 months in casks made of 10 types of wood were studied. The ethanol content, volatile acidity, aldehydes, esters, higher alcohols, and methanol were determined. In addition, gallic, vanilic and syringic acids, siringaldehyde, coniferaldehyde, sinapaldehyde, vanillin, 5-hydroxymethylfurfural and furfural were identified and quantified. The profile of volatile compounds characterised aging in each type of wood. The beverage aged in oak cask achieved the highest contents of maturation-related congeners. The Brazilian woods, similar to oak, were jequitibá rosa and cerejeira, which presented the highest contents of some maturation-related compounds, such as vanillin, vanilic acid, syringaldehyde and sinapaldehyde. Although oak wood conferred more chemical complexity to the beverage, Brazilian woods, singly or complementarily, present potential for spirit characterisation and for improving the quality of sugar cane spirits.

INAA and AAS of different products from sugar cane industry in Pakistan. Toxic trace elements for nutritional safety

International Nuclear Information System (INIS)

Waheed, S.; Rahman, S.; Gill, K.P.

2009-01-01

Instrumental neutron activation analysis (INAA) have been used to determine As, Br, Hg, Sb and Se in combination with atomic absorption spectrometry (AAS) as a complementary technique for the quantification of Cd and Pb in jaggery, brown sugar, white sugar and molasses. All sugar cane products were collected from the local sugar cane industry of Pakistan. The highest concentration of these potentially toxic elements was quantified in molasses; however, molasses together with jaggery, brown sugar and white sugar contains trace amounts of all of these elements. Due to very low concentration of Cd it could only be detected in molasses. To evaluate the percentage contribution of these elements in the sugar cane products to the weekly recommended values, intakes on weekly consumption of 100 g of each item have also been calculated which follow the pattern Br>Se>Pb>Hg>As>Sb. The elevated Br contents may be attributed to the use of Br-containing chemicals for fumigation; however, these contents are well within the tolerance levels. The estimated weekly intake of all toxic elements is very low indicating that sugar cane products can be safely ingested as part of the diets. (author)

2013-07-25

Blast furnace slag (BFS)/sugar cane bagasse ash (SCBA) blends were assessed for the production of alkali-activated pastes and mortars. SCBA was collected from a lagoon in which wastes from a sugar cane industry were poured. After previous dry and grinding processes, SCBA was chemically characterized: it had a large percentage of organic matter ( ca. 25%). Solutions of sodium hydroxide and sodium silicate were used as activating reagents. Different BFS/SCBA mixtures were studied, replacing part of the BFS by SCBA from 0 to 40% by weight. The mechanical strength of mortar was measured, obtaining values about 60 MPa of compressive strength for BFS/SCBA systems after 270 days of curing at 20 °C. Also, microstructural properties were assessed by means of SEM, TGA, XRD, pH, electrical conductivity, FTIR spectroscopy and MIP. Results showed a good stability of matrices developed by means of alkali-activation. It was demonstrated that sugar cane bagasse ash is an interesting source for preparing alkali-activated binders.

Effect of gamma-radiation on sugar cane spirit

International Nuclear Information System (INIS)

Souza, Maria Djiliah Camargo Alvarenga de

2000-01-01

Irradiation has appeared as an alternative technique in food preservation. Besides cold decontamination irradiation can increase the quality of the food through the improvement of technological properties. For alcoholic beverages ionizing radiation has been applied to wines, whiskeys and beers in countries such as Thailand and China. In those cases, the purpose of the technique was to accelerate aging, to improve the sensory characteristics and as sterilization treatment. The aim of this work was to study the effect of gamma radiation on the quality of sugar cane spirit by gas chromatography analysis of volatile compounds and sensory analysis. The sugar cane spirit newly distilled samples and commercial samples from different states (SP, CE and RJ) were irradiated either in glass or oak cask (Quercus alba sp) in a 60 Co Gammacell 220 at dose rate of 7.7 kGy/h and total doses of 0; 0.1; 2; 5 and 10 kGy. The analytical determination of esters, acetaldehyde and higher alcohols were performed in a gas chromatograph with flame ionization detector employing a Megabore CG-745 column. The alcoholic graduation was measured in a Gay-Lussac alcohometer and the pH was determined using an Analyser 300 pHmeter. The color change was measured by the absorbance at 420 nm in a Shimadzu UV 1601 spectrophotometer. The acceptance tests related to odor, taste, global impression and color were analyzed using Tukey average tests (p ≤0,05), ANOVA and histograms of panelists' scores frequency. A correlation between acetaldeyde, esters, higher alcohols levels and radiation dose was found in the sugar cane spirit newly distilled samples irradiated in oak cask and commercial samples. An increase in methanol concentration was verified, although remaining enough below the permissible limit accepted by the Brazilian Legislation. A decrease in the alcoholic graduation and pH in the irradiated samples was observed. A slight discoloration in the irradiated samples was verified. According to ANOVA

The Camberwell Assessment of Need for the Elderly (CANE) was developed for the assessment of physical-, psychological-, and environment-related needs in the elderly. The aim of this study was to revise and adapt the German version of the CANE with regard to the content validity of the instrument. Following a multistage approach, face-to-face interviews using the CANE, an expert survey and a multidisciplinary consensus conference were conducted in order to evaluate the frequency and relevance of met and unmet needs in the German elderly population, and to modify the content of the CANE for the German-speaking countries. In Germany, unmet physical needs including physical health, medication, eyesight/hearing/communication, mobility/falls, self-care, and continence were found to have top priority closely followed by social needs (company, intimate relationships, daytime activities, information, and abuse/neglect). Psychological needs were the lowest ranked care category. Experts' proposals for the improvement of the German version of the CANE were collected. All findings were discussed and integrated in the multidisciplinary consensus conference with the result of a revised and adapted CANE that is applicable in the German-speaking context. The provision of an adapted and improved German version of the CANE may substantially contribute to a comprehensive and valid assessment of needs in the elderly population. The results of this study represent an important basis for comprehensive needs assessment in the elderly in the theoretical and practical field of healthcare and health services research.

Contextual-Based Knowledge Creation for Agroindustrial Innovation

Full Text Available This paper discusses the knowledge creation process in one department, in a higher educational context, and the possible actions to take to improve the efficiency and effectiveness of the knowledge creation system in it. We conducted a case study at one department of a university that strives to improve its innovations, in terms of their quantity and quality.We used a soft system methodology to investigate the knowledge creation system in the chosen department. From the study, we conclude that the department can be considered as a learning organization, within which its staff continually create, acquire and transfer knowledge. This department has a learning environment which is conducive, concrete learning processes, and leadership that reinforces learning. In the context of producing agroindustry innovations, the knowledge creation system in this department is considered to be less effective since it frequently happens more at individual or small group levels. To improve its effectiveness, the management may facilitate the institutionalization of knowledge creation processes at every phase of the interactions between tacit and explicit knowledge.

Bioenergy from agro-industrial residues in the East African region. Summary report

Tanzania has recently developed a comprehensive environmental policy which has put high priority on several specific environmental issues. One of the issues is the quality of waste water. A special priority is given to the pollution from the sisal industry. The East-African agro-industries generate very large quantities of organic residues from production and processing of different crops. These residues form a major contribution to the pollution of air, soil and waterways, but, at the same time they constitute a large potential for production of bioenergy through anaerobic digestion as well as potential substrate for other biological fermentation processes. Generally, these residues are regarded as having no or very little value and the different disposal methods are mainly a matter of getting rid of the waste. The generation of residues are very often concentrated on few large units, which makes the exploitation of these resources feasible in large scale biogas systems. Typically the units will have a potential of a daily methane generation of 1,000-20,000 m{sup 3} CH{sub 4}, equivalent to a potential electricity production of 0.2-3.2 MW. The future utilization of these resources for production of valuable products is described in this report. This report consists of 3 volumes. This summary report including the main objectives and findings from the different project report: Mapping and Quantification of Organic Agro-Industrial Residues in East Africa; Biogas - Bioenergy Potential in East Africa, Seminar Proceedings, Siler Sands, Dar es Salaam 22-23 September 1997; Bioenergy from Sisal residues - Experimental results and Capacity Building Activities.

Locomotor performance of cane toads differs between native-range and invasive populations.

Kosmala, Georgia; Christian, Keith; Brown, Gregory; Shine, Richard

2017-07-01

Invasive species provide a robust opportunity to evaluate how animals deal with novel environmental challenges. Shifts in locomotor performance-and thus the ability to disperse-(and especially, the degree to which it is constrained by thermal and hydric extremes) are of special importance, because they might affect the rate that an invader can spread. We studied cane toads ( Rhinella marina ) across a broad geographical range: two populations within the species' native range in Brazil, two invasive populations on the island of Hawai'i and eight invasive populations encompassing the eastern, western and southern limits of the toad invasion in Australia. A toad's locomotor performance on a circular raceway was strongly affected by both its temperature and its hydration state, but the nature and magnitude of those constraints differed across populations. In their native range, cane toads exhibited relatively low performance (even under optimal test conditions) and a rapid decrease in performance at lower temperatures and hydration levels. At the other extreme, performance was high in toads from southern Australia, and virtually unaffected by desiccation. Hawai'ian toads broadly resembled their Brazilian conspecifics, plausibly reflecting similar climatic conditions. The invasion of Australia has been accompanied by a dramatic enhancement in the toads' locomotor abilities, and (in some populations) by an ability to maintain locomotor performance even when the animal is cold and/or dehydrated. The geographical divergences in performance among cane toad populations graphically attest to the adaptability of invasive species in the face of novel abiotic challenges.

[Walking with canes and forearm-crutches (author's transl)].

Bergmann, G; Kölbel, R; Rauschenbach, N; Rohlmann, A

1978-02-01

Partial weight bearing is frequently prescribed but cannot be controlled adequately. In a previous paper the change of forces at the hip joint as effected by a one sided cane was determined by instrumentation of the cane and a mechanical analysis of gait on a walkway. In the present study we looked at the conditions for control of partial weightbearing when two forearm crutches are used. Instrumented crutches and a forceplate were used. In walking with two forearm crutches the total of the ground reaction forces and the force pattern differ from those in free walking. The total of two crutch forces plus the force at the leg with partial weightbearing exceeds that caused by body weight alone. This is due to mass accelerations in a changed gait pattern. When the maximal leg force is reduced from 100% body weight to zero, the additional dynamic forces exceed those caused by body weight alone by 4%-19%. Only 2% of the additional dynamic forces act on the controlateral crutch while the rest is transmitted through the ipsilateral crutch. The crutch force pattern on the ipsilateral side depends more on individual gait characteristics than does that on the controlateral side. Load reduction is more pronounced in the late stages of the stand phase than in the early ones.

Full Text Available Protection of agro-industry in emergency situations is of vital importance for economic and social development of a country. This paper is therefore created with a view of assessing the degree of resilience of economic entities within agro-industrial sector in the Autonomous Province (AP of Vojvodina and partially in the Republic of Serbia in emergency situations, so that measures to increase their competitiveness could be undertaken. The methods adequate for social sciences were used: positive law method, logical induction and deduction, multidisciplinary approach, as well as statistical method. The research established that the economic entities mainly have their own fire rescue and procedure plans, but not emergency action plans. Special financial assets have not been allocated for that purpose either. Businessmen are not acquainted with the existence of ISO 22301:2012 standard, which may be exceptionally useful in solving this problem. The degree of resilience of economic entities in the AP of Vojvodina in emergency situations is 64.2%. It is necessary in the forthcoming period to improve the implementation of regulations, particularly in the field of emergency action plans, but also the possibilities to implement ISO 22301:2012 standard.

Sugarcane is currently the most efficient bioenergy crop with regards to the energy produced per hectare. With approximately half the global bioethanol production in 2005, and a devoted land area expected to expand globally in the years to come, sugar cane is at the heart of the biofuel debate. Dynamic global vegetation models coupled with agronomical models are powerful and novel tools to tackle many of the environmental issues related to biofuels if they are carefully calibrated and validated against field observations. Here we adapt the agro-terrestrial model ORCHIDEE-STICS for sugar cane simulations. Observation data of LAI are used to evaluate the sensitivity of the model to parameters of nitrogen absorption and phenology, which are calibrated in a systematic way for six sites in Australia and La Reunion. We find that the optimal set of parameters is highly dependent on the sites' characteristics and that the model can reproduce satisfactorily the evolution of LAI. This careful calibration of ORCHIDEE-STICS for sugar cane biomass production for different locations and technical itineraries provides a strong basis for further analysis of the impacts of bioenergy-related land use change on carbon cycle budgets. As a next step, a sensitivity analysis is carried out to estimate the uncertainty of the model in biomass and carbon flux simulation due to its parameterization.

Naringinase-producing microorganisms were isolated locally from some citrus fruits and soil using a culture enrichment technique, and they were tested for their enzyme producing ability in shake flask cultures. Among the tested microorganisms, aspergillus niger-AH3 proved to be the most potent active isolate which gave 92.1 UMl -1 of naringinase activity in fermentation medium. Optimization effects of various fermentation medium constituents of agro-industrial processing wastes as substrates for naringinase production were studied. Of substrates used, corn steep liquor, soya bean meal, jojoba seed meal and bitter orange seed powder were the best for naringinase production .Maximum enzyme titer (145.5 Uml -1 ) was obtained in the optimized fermentation medium supplemented with 0.5% CaCo 3 after 120 h of incubation. The highly potent ten enhanced isolates which were selected after treatment with gamma irradiation, had significantly elevated titers of naringinase activity compared with the parental wild strain A. niger-AH3. Enhanced isolate A. niger-AH3. γ20 derived from 2.0 kGy treated groups is exhibiting the highest enzyme activity 1.5 folds higher than parental strain. This suggests that a process for efficient utilization of the agro-industrial processing wastes in economical production of naringinase in large quantities which would be suitable for debittering process in the citrus fruit juice industry

The current demographic and social developments in our society will lead to a significant increase in treatment and healthcare needs in the future, particularly in the elderly population. The Camberwell Assessment of Need for the Elderly (CANE) was developed in the United Kingdom to measure physical-, psychological-, and environment-related treatment as well as healthcare needs of older people in order to identify their unmet needs. So far, the German version of the CANE has not been established in health services research. Major reasons for this are a lack of publications of CANE's German version and the missing validation of the instrument. The aims of the present study were to evaluate the currently available German version of the CANE in a sample of older primary care patients. Descriptive statistics and inference-statistical analyses were calculated. Patients reported unmet needs mostly in CANE's following sections: mobility/falls, physical health, continence, company, and intimate relationships. Agreement level between patients' and relatives' ratings in CANE was moderate to low. Evidence for the construct validity of CANE was found in terms of significant associations between CANE and other instruments or scores. The study results provide an important basis for studies aiming at the assessment of met and unmet needs in the elderly population. Using the German version of the CANE may substantially contribute to an effective and good-quality health and social care as well as an appropriate allocation of healthcare resources in the elderly population.

Changes in the quality attributes of non-centrifugal cane brown sugar represented by physicochemical characteristics as well as flavour components and Maillard reaction products (MRPs) were monitored every 3 months over 1 year of storage. Stored cane brown sugar became darker, and its moisture content and water activity (a(w)) increased during storage. Fructose and glucose levels decreased as non-enzymatic browning via the Maillard reaction occurred in the stored sample, and a similar trend was also discovered in aconitic and acetic acids. Stored cane brown sugar lost its acidic and sulfuric odours (58.70-39.35% and 1.85-0.08%, respectively); subsequently, the nutty and roasted aroma increased from 26.52% to 38.59% due to the volatile MRPs. The browning rate of stored cane brown sugar was positively associated with the development of volatile MRPs (Pearson's coefficient = 0.860), whereas the amount of 3-deoxyglucosone, an intermediate product of the Maillard reaction, had a lower association with the brown colour due to its relatively slow degradation rate.

Under land and climate change scenarios, agriculture has experienced water competitions among other sectors in the São Paulo state, Brazil. On the one hand, in several occasions, in the northeastern side of this state, nowadays sugar-cane is expanding, while coffee plantations are losing space. On the other hand, both crops have replaced the natural vegetation composed by Savannah and Atlantic Coastal Forest species. Under this dynamic situation, geosciences are valuable tools for evaluating the large-scale energy and mass exchanges between these different agro-ecosystems and the lower atmosphere. For quantification of the energy balance components in these mixed agro-ecosystems, the bands 1 and 2 from the MODIS product MOD13Q1 were used throughout SAFER (Surface Algorithm for Evapotranspiration Retrieving) algorithm, which was applied together with a net of 12 automatic weather stations, during the year 2015 in the main sugar cane and coffee growing regions, located at the northeastern side of the state. The fraction of the global solar radiation (RG) transformed into net radiation (Rn) was 52% for sugar cane and 53% for both, coffee and natural vegetation. The respective annual fractions of Rn used as λE were 0.68, 0.87 and 0.77, while for the sensible heat (H) fluxes they were 0.27, 0.07 and 0.16. From April to July, heat advection raised λE values above Rn promoting negative H, however these effects were much and less strong in coffee and sugar cane crops, respectively. The smallest daily Rn fraction for all agro-ecosystems was for the soil heat flux (G), with averages of 5%, 6% and 7% in sugar cane, coffee and natural vegetation. From the energy balance analyses, we could conclude that, sugar-cane crop presented lower annual water consumption than that for coffee crop, what can be seen as an advantage in situations of water scarcity. However, the replacement of natural vegetation by sugar cane can contribute for warming the environment, while when this

Due to low degradability of dry solids, most of the digesters at wastewater treatment plants (WWTP) operate at low loading rates resulting in poor biogas yields. In this study, co-digestion of sewage sludge (SS) with olive mill wastewater (OMW), cheese whey (CW) and crude glycerol (CG) was studied in an attempt to improve biogas production of existing digesters at WWTPs. The effect of agro-industrial by-products in biogas production was investigated using a 220L pilot-scale (180L working volume) digester under mesophilic conditions (35°C) with a total feeding volume of 7.5L daily and a 24-day hydraulic retention time. The initial feed was sewage sludge and the bioreactor was operated using this feed for 40days. Each agro-industrial by-product was then added to the feed so that the reactor was fed continuously with 95% sewage sludge and 5% (v/v) of each examined agro-industrial by-product. The experiments showed that a 5% (v/v) addition of OMW, CG or CW to sewage sludge significantly increased biogas production by nearly 220%, 350% and 86% as values of 34.8±3.2L/d, 185.7±15.3L/d and 45.9±3.6L/d respectively, compared to that with sewage sludge alone (375ml daily, 5% v/v in the feed). The average removal of dissolved chemical oxygen demand (d-COD) ranged between 72 and 99% for organic loading rates between 0.9 and 1.5kgVSm -3 d -1 . Reduction in the volatile solids ranged between 25 and 40%. This work suggests that methane can be produced very efficiently by adding a small concentration (5%) of agro-industrial by-products and especially CG in the inlet of digesters treating sewage sludge.

Larson, E.D.; Williams, R.H.; Ogden, J.M.; Hylton, M.G.

1991-01-01

Steam injection for power and efficiency augmentation in aeroderivative gas turbines has been commercially established for natural gas-fired cogeneration since 1980. Steam-injected gas turbines fired with coal and biomass are being developed. A performance and economic assessment of biomass integrated-gasifier steam-injected gas turbine (BIG/STIG) cogeneration systems is carried out here. A detailed economic case study is presented for the second largest sugar factory in Jamaica, with cane residues as the fuel. BIG/STIG cogeneration units would be attractive investments for sugar producers, who could sell large quantities of excess electricity to the utility, or for the utility, as a low-cost generating option. Worldwide, the cane sugar industry could support some 50,000 MW of BIG/STIG electric generation capacity. The relatively modest development effort required to commercialize the BIG/STIG technology is discussed in a companion paper prepared for this conference

In the present work the concentrations of essential elements Ca (calcium), CI (chlorine), K (potassium), Mg (magnesium), Na (sodium), Co (cobalt), Cr (chromium), Cu (copper), Fe (iron), Mn (manganese). Mo (molybdenum), Se (selenium), V (vanadium) and Zn (zinc), the toxic elements As (arsenic), Cd (cadmium) and Hg (mercury) and the elements without defined functions to the animal metabolism, such as Br (bromine), Eu (europium). La (lanthanum), Rb (rubidium), Sb (antinomies), Sc (scandium), Ta (tantalum), Th (thorium) and U (uranium) were determined in agroindustrial by-products employed in animal feeding by instrumental neutron activation analysis (INAA). Forty samples of agroindustrial by-products were analyzed, six of which are from animal origin and the others are from vegetable origin. All these materials are widely used in bovine feeding, mainly in dry season, when the forage become scarce. The precision and accuracy of the method were evaluated by means of analysis of the following certified reference materials: Rice Flour NIES-CRM-10C, Pig Kidney BCR-CRM, Oyster Tissue NIST-SRM-1566a e Buffalo River Sediment NIST-SRM-2704. The results, in general, are lower than 10 %. The results for the most of essential minerals were lower than the toxic limit for animals, and they reached the minimum requirements for domestic animals, although some agroindustrial by-products showed concentrations lower than the requirement. For all samples, the concentrations of toxic minerals were lower than the toxic limit (author)

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)

Full Text Available The deposition of organic residues through mechanical harvesting of cane sugar is a growing practice in sugarcane production system. The maintenance of these residues on the soil surface depends mainly on environmental conditions. Nitrogen fertilization on dry residues tend to retard decomposition of these, providing benefits such as increased SOM. Thus, the object of this research was to evaluate the effect of different doses of nitrogen on sugar cane crop residues, as its decomposition and contribution to carbon sequestration in soil. The experiment was conducted in Dourados-MS and consisted of a randomized complete block design. Dried residues were placed in litter bags and the treatments were arranged in a split plot, being the four nitrogen rates (0, 50, 100 and 150 kg ha-1 N the plots, and the seven sampling times (0, 30, 60, 90, 120, 150 and 180 the spit plots. Decomposition rates of residues, total organic carbon and labile carbon on soil were analysed. The application of increasing N doses resulted in an increase in their decomposition rates. Despite this, note also the mineral N application as a strategy to get higher levels of labile carbon in soil.

Being one of Ukraine’s major sources of economic revenue, the country’s agroindustrial sector proved, at the same time, to be perhaps the most vulnerable branch of economy in the times of political and social turbulence. While the state is searching for the ways of strengthening its positions at the global market, its agricultural potential to a considerable extent remains both under- and misused. The cluster approach has become in recent years as a key instrument of municipal economic policies of the leading industrialized countries. Utilizing the experience of other European countries’ with regards to making agriculture more sustainable and competitive in the modern world, the author describes the ways of applying these practices against the background of Ukrainian agribusiness system. Innovation of our research presented as adaptation policy measures for clustering Ukrainian agribusiness and the structure of corn production cluster in Ukraine is proposed. The basic elements of government policy in supporting the development of agricultural clusters are proposed. The ways of creating the Agro Industries clusters are described.

The sugar cane bagasse fiber are renewable materials and have great application potential when used as reinforcement in a polymer matrix to give rise to composite materials and as supports for adsorption of heavy metals. This paper therefore describes the preparation and characterization of bleached and hydrated zirconium oxide modified sugar cane bagasse fiber by conventional precipitation method. Through the technique of electron microscopy we observed the presence of oxide nanoparticles on the fiber surface, proving the efficiency of the conventional precipitation method. With the X-ray diffraction analysis it was determined a decrease of 6.2% in the crystallinity index of modified fibers when compared to the bleached fibers showing the deposition of amorphous zirconium oxide on the fiber surface.

The mineralized and volatilized nitrogen derived from vinasse labelled with 15 N were determined in a laboratory experiment, using samples of two soils [a sandy Red-Yellow-Podzolic-PV and a clayey Latosol - LR (Oxisol)], collected in Piracicaba, SP, Brazil. The experiment consisted of four treatments: application of vinasse (V * ); vinasse with urea (V * +U); vinasse with sugar cane straw (V * +P); and vinasse with urea and sugar cane straw (V * +U+P). Vinasse, labelled with 15 N (V * ) was applied at a rate of 100 mg.kg -1 of N-vinasse. All treatments, were incubated for 7, 14, 21, 28 and 35 days. N-urea and sugar cane straw were incorporated in the soil at rates of 220 mg.kg -1 and 22 g.kg -1 , respectively. N H 4 + -N and NO 3 - -N concentrations, as a result of the vinasse addition, were affected by soil type. A larger availability of N H 4 + -N and NO 3 - -N derived from vinasse were observed, when urea was added. Sugar cane straw plus vinasse did not alter the concentrations of N H 4 + - N and NO 3 - - N derived from vinasse. Urea plus sugar cane straw did not affect N H 4 + -N concentrations, and affected the NO 3 - -N concentration in LR soil over time. Losses of vinasse-N, due to volatilization, increased with time for all treatments, and were larger for PV (14%) than for LR(5%); but such losses were similar in LR soil. (author)

To reduce the fermentation cost for industrialization of chlorothalonil hydrolytic dehalogenase (Chd), agro-industrial wastewaters including molasses, corn steep liquor (CSL) and fermentation wastewater were used to substitute for expensive carbon and nitrogen sources and fresh water for lab preparation. The results showed that molasses and CSL could replace 5% carbon source and 100% organic nitrogen source respectively to maintain the same fermentation level. Re-fermentation from raffinate of ultra-filtered fermentation wastewater could achieve 61.03% of initial Chd activity and reach 96.39% activity when cultured in a mixture of raffinate and 50% of original medium constituent. Typical raw foods were chosen to evaluate the chlorothalonil removal ability of Chd. After Chd treatment for 2 h at room temperature, 97.40 and 75.55% of 30 mg kg -1 chlorothalonil on cherry tomato and strawberry respectively and 60.29% of 50 mg kg -1 chlorothalonil on Chinese cabbage were removed. Furthermore, the residual activity of the enzyme remained at 78-82% after treatment, suggesting its potential for reuse. This study proved the cost-feasibility of large-scale production of Chd from agro-industrial wastewater and demonstrated the potential of Chd in raw food cleaning. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

The aim of this study was to assess the seasonal price of sugar cane, fuel alcohol (hydrated and anhydrous) and electricity tariffs as a way of aiding tool for optimization of energy generation, using biomass originating from cane sugar. Using the method of moving average centered was concluded that cane and electricity rates were close to seasonal average, with low range of prices, suggesting the non-occurrence of seasonal variation in prices. Unlike the seasonal indices of ethanol showed seasonal variation of prices with greater amplitude of seasonal index. Thus, the results suggest that the utilization of by-products of sugar cane to produce electrical power points to the prospect of reducing risks associated with variations in the price of ethanol, thereby contributing to greater stability and possibility to those involved in planning alcohol sector.

Sugar cane bagasse was submitted to ethanol organosolv pre-treatment using a 50 L pilot scale reactor. The influence of catalyst type (H 2 SO 4 or NaOH), catalyst concentration (1.25-1.50% w/w on dry fiber) and process time (60-90 min) on total solid recovery and solid composition (glucan, xylan and lignin contents) was evaluated by performing a 2 3 full factorial experimental design. Pretreated sugar cane bagasse was further submitted to enzymatic hydrolysis using a commercial enzyme complex formed by cellulases and β-glucosidases. Glucose concentration in the hydrolysates and glucose yield referred to initial raw material (g glucose/100 g sugar cane bagasse) were used to select the best operational conditions. Concerning the enzymatic hydrolysis, the resulting glucose concentration was found to be dependent on xylan contents of the pretreated material. The modelling equations for glucose concentration and glucose yield as a function of the pre-treatment variables and the statistical analysis are also discussed in this work.

2010-06-01

Full Text Available Abstract Background A parasite morphologically indistinguishable from Myxidium immersum (Myxozoa: Myxosporea found in gallbladders of the invasive cane toad (Bufo marinus was identified in Australian frogs. Because no written record exists for such a parasite in Australian endemic frogs in 19th and early 20th century, it was assumed that the cane toad introduced this parasite. While we cannot go back in time ourselves, we investigated whether material at the museum of natural history could be used to retrieve parasites, and whether they were infected at the time of their collection (specifically prior to and after the cane toad translocation to Australia in 1935. Results Using the herpetological collection at the Australian Museum we showed that no myxospores were found in any animals (n = 115 prior to the cane toad invasion (1879-1935. The green and golden bell frog (Litoria aurea, the Peron's tree frog (Litoria peronii, the green tree frog (Litoria caerulea and the striped marsh frog (Limnodynastes peronii were all negative for the presence of the parasite using microscopy of the gallbladder content and its histology. These results were sufficient to conclude that the population was free from this disease (at the expected minimum prevalence of 5% at 99.7% confidence level using the 115 voucher specimens in the Australian Museum. Similarly, museum specimens (n = 29 of the green and golden bell frog from New Caledonia, where it was introduced in 19th century, did not show the presence of myxospores. The earliest specimen positive for myxospores in a gallbladder was a green tree frog from 1966. Myxospores were found in eight (7.1%, n = 112 frogs in the post cane toad introduction period. Conclusion Australian wildlife is increasingly under threat, and amphibian decline is one of the most dramatic examples. The museum material proved essential to directly support the evidence of parasite emergence in Australian native frogs. This parasite can be

Vinasse, produced by several countries as a by-product of agricultural activity, has different alternatives for its reuse, mainly fertirrigation. Several monocultures, such as sugar cane and orange crops, produce this effluent. Sugar cane vinasse is already widely used in fertirrigation and orange vinasse has potential for this intention. However, its use as a fertilizer has caused great concern. Thus, ecotoxicological evaluation is extremely important in order to assess the possible effects on the environment. Therefore, the aim of this study was to evaluate the potential toxicity of vinasse of two different crops: sugar cane and orange. For this purpose, bioassays with Allium cepa as a test organism were performed with two vinasse dilutions (2.5% and 5%) to detect chromosomal aberrations and micronucleus induction. The results showed that both types of vinasse are able to induce chromosomal aberrations in meristematic cells, mainly nuclear and anaphasic bridges, suggesting genotoxic potential. The induction of micronuclei in cells of the F 1 region suggests that the two residues have mutagenic potential. Thus, caution is advised when applying these effluents in the environment.

Full Text Available Starch nutritional fractions as well as thermal properties and other analysis are essential for food and industrial application. Cassava bagasse is an important agro-industrial residue and its starch content was evaluated using two alternative methods. Thermal characterization and microscopy analyses helped to understand how hydrolysis digests starchy fraction of cassava bagasse. The melting point of cassava starch occurred at 169.2ºC. Regarding TG analyses, after moisture content, there were observed two main mass losses for all samples. Results suggest hydrolysis carried out using enzyme is less effective in order to convert total starch content in cassava bagasse. However, using sulfuric acid, fibers are affected by analyses conditions.As frações nutricionais bem como as propriedades térmicas e outras análises são essenciais para a indústria de alimentos e suas aplicações O bagaço de mandioca é um importante resíduo agroindustrial e seu teor de amido foi avaliado por dois métodos alternativos.

E-mail: camilamendes1009@gmail.com Stomoxys calcitrans fly is one of the dipterans of importance for livestock farming due to the considerable economic losses it determines worldwide. An aspect that favors the occurrence of this insect's outbreaks in Brazil is the generation of large quantities of by-products from the alcohol industry, such as vinasse, sugarcane straw, bagasse, filtercake and ashes. The present study aimed to evaluate the possible interference of vinasse and ashes on the immature stages of S. calcitrans, by comparing the biological parameters observed with or without the presence of these substrates. In Experiment I, three groups of 50 eggs were deposited in a diet composed of one kilogram of chopped cane and 250mL, 500mL and 1L of vinasse (groups 1, 2 and 3. In the control groups, distilled water was added to the chopped cane in the same proportions used in the groups treated with vinasse. In Experiment II, three groups of 50 larvae from eight to 10 days of emergence were deposited on a diet composed of cane, vinasse and ashes. The ashes were used in the proportion of 1, 2 and 3% (groups 1, 2 and 3 of sugar cane (100g and vinasse was used in the proportion of 100mL for all groups and their respective controls. The control group contained only sugarcane and vinasse. Both experiments were kept in a climatized chamber (27 ± 1°C and 70-80% RH, and three replications were performed.

Three spectrophotometric methods were developed for the determination of copper (Cu) in sugar cane spirit using the chromogenic reagents neocuproine, cuprizone, and bathocuproine. Experimental conditions, such as reagent concentration, reducer concentration, pH, buffer concentration, the order of addition of reagents, and the stability of the complexes, were optimized. The work range was established from 1.0 to 10.0 µg/mL, with correlation coefficients of >0.999 for all three optimized methods. The methods were evaluated regarding accuracy by addition and recovery tests at five concentration levels, and the obtained recoveries ranged from 91 to 105% (n = 3). Precision was expressed as RSD (relative standard deviation), with values ranging from 0.01 to 0.17% (n = 10). The method using the chromogenic reagent cuprizone presented the greatest molar absorptivity, followed by bathocuproine and neocuproine. The methods were applied for the determination of Cu in sugar cane spirit, and the results were compared with a reference method by flame atomic absorption spectrometry (FAAS). Calibration curve solutions for FAAS analysis were prepared in a 40% (v/v) alcohol medium in a range of concentrations from 0.5 up to 5 µg/mL. Measurements for Cu determination were carried out at a wavelength of 324.7 nm. The concentrations obtained for Cu in sugar cane spirit samples from Brazil were between 1.99 and 12.63 µg/mL, and about 75% of the samples presented Cu concentrations above the limit established by Brazilian legislation (5.0 µg/mL or 5.0 mg/L).

The objective of this work was to evaluate the recovery, by plant cane, of the nitrogen ( 15 N) from urea and from sugarcane (Saccharum spp.) crop residues - straw and root system - incorporated into the soil. The experiment was settled in 2005/2006 with the sugarcane cultivar SP81 3250. At planting, microplots of 2 m length and 1.5 m width were installed, and N applications were done with 80 kg ha-1 N (urea with 5.05% in 15 N atoms) and 14 Mg ha -1 crop residues - 9 Mg ha -1 of sugarcane straw and 5 Mg ha -1 of root system, labeled with 15 N (1.07 and 0.81% in 15 N atoms, respectively). The total N accumulation by plants was determined during the crop cycle. Although the N use by shoot from crop residue mineralization (PA and SR) increased significantly over time, this source hardly contributed to crop nutrition. The recovery of the 15 N-urea, 15 N-SS and 15 N-RS by plant cane was 30.3 +- 3.7%, 13.9 +- 4.5% and 6.4 +- 0.9%, respectively, representing 15.9, 4.7 and 1.4% of total nitrogen uptake by shoot.

Problems related to the use of personal protective equipment (PPE), specially the use of protective gloves for the manual sugar cane cutting, motivated this research, made possible by a tripartite negotiation involving the Ministry of Labor, the Union of Rural Workers and the Employer's Association of sugarcane agribusiness. The main objective was to evaluate, from an ergonomics perspective, the impact of use of the gloves during the manual cane sugar cutting, raising questions on safety, effectiveness and comfort. The research was carried in a sugarcane industry of São Paulo for two seasons involving 47 workers who made a qualitative analysis of acceptance of four models of protective gloves. The methodology included the use of semi-structured interviews, questionnaires and field observations and the experimental determination of the coefficient of static friction developed between the gloves and the surfaces of the machete handle. The main results indicate the general inadequacy of the gloves currently used forcing the employees to improvise. Workers found the glove of leather and nylon scraping the best reported for comfort in use. The overall results highlight the problem of detachment of test standards for the manufacture of PPE, ignoring users and the activity to be performed.

Sugar cane consumption on Rapanui (Easter Island) and the indicence of caries : evidence from stable isotope values of human bone

Leach, B.F.; Quinn, C.J.; Seelenfreund, A.

Pre-European people on Rapanui are known to have had a high rate of dental caries. One proposed explanation for this is that the people consumed a considerable amount of sugar cane, as a thirst quencher, since fresh water is scarce on the island. Human bone samples were analysed by isotope analysis to see if this explanation could be sustained. Results for three isotopes δ"1"3C, δ"1"5N and δ"3"4S were then used in a stochastic model to estimate the proportions of five main food types in the diet of these people. This indicated that daily consumption of dry raw sugar cane was only about 32 to 42 g per day. This is very low and sugar cane consumption is therefore unlikely to be the only cause of the high rate of dental caries. (author).

Full Text Available The effect of cane girdling on skin colour, harvest date, yield, and some quality characteristics of Vitis vinifera L. cv. Red Globe table grape variety, was measured over two growing seasons, 2013–2014, at the facility of Manisa Viticulture Research Station in Turkey. Cane girdling was performed on the spurs after first bud was left from the bottom and 4 mm-wide ring of bark was completely removed with a doubleded knife at veraison period. Statistical analyses showed that total soluble solid content, berry width, berry length, colour parameters, CIRG index and anthocyanin content of the Red Globe was significantly affected by the girdling treatment in both years, 2013 and 2014. In addition it was detected that any effect of girdling treatments cannot be determined statistically significant on total yield, marketable yield, total phenolics, titrable acidity, pH and 50 berry weight. Total and marketable yields of girdled vines had higher value although they weren’t statistically significant. Furthermore it was observed on girdled vines 7 and 11 days earliness compare to the control vines in 2013 and 2014, respectively.

For Plant CIVAC of Nissan Mexicana, the energy saving began in the year of 1990. From then, different programs have been developed using different strategies for energy saving until arriving at the Benchmarking with other Plants of Japan, which represents a new challenge, since it opened up an area of opportunity of saving in processes that generally were known in detail as far as to its main function (to make vehicles with quality, cost and opportunity of delivery), but the parameter of energy consumption of by unit and its benefits in relation to the cost was unknown. This was endorsed by the high Direction and began with the optimization of training for the operation of each equipment with the involvement of the user (Production), the engineering area (that establishes the process) and the maintenance area. We designed a general program where the basic activities were included, such as the general and special activities. Each one of them fulfilled its objective, but the special activities took us to the optimization of the processes, finding excess of energy in the design conditions.

Soil, water and nutrient losses by interrill erosion from green cane cultivation

Directory of Open Access Journals (Sweden)

Gilka Rocha Vasconcelos da Silva

2012-06-01

Full Text Available Interrill erosion occurs by the particle breakdown caused by raindrop impact, by particle transport in surface runoff, by dragging and suspension of particles disaggregated from the soil surface, thus removing organic matter and nutrients that are essential for agricultural production. Crop residues on the soil surface modify the characteristics of the runoff generated by rainfall and the consequent particle breakdown and sediment transport resulting from erosion. The objective of this study was to determine the minimum amount of mulch that must be maintained on the soil surface of a sugarcane plantation to reduce the soil, water and nutrient losses by decreasing interrill erosion. The study was conducted in Pradópolis, São Paulo State, in 0.5 x 1.0 m plots of an Oxisol, testing five treatments in four replications. The application rates were based on the crop residue production of the area of 1.4 kg m-2 (T1- no cane trash; T2-25 % of the cane trash; T3- 50 % trash; T4-75 % trash; T5-100 % sugarcane residues on the surface, and simulated rainfall was applied at an intensity of 65 mm h-1 for 60 min. Runoff samples were collected in plastic containers and soon after taken to the laboratory to quantify the losses of soil, water and nutrients. To minimize soil loss by interrill erosion, 75 % of the cane mulch must be maintained on the soil, to control water loss 50 % must be maintained and 25 % trash controls organic matter and nutrient losses. This information can contribute to optimize the use of this resource for soil conservation on the one hand and the production of clean energy in sugar and alcohol industries on the other.

2014-05-01

Brazil is the largest producer of cane sugar, consequently, is a leader in the production of bio-ethanol, a clean and renewable energy that fits the model of sustainable economy as discussed and pursued by our society. Our state of São Paulo concentrates 60% of national production, representing a sizeable share in the range of world production. All this economic potential is closely monitored by the scientific community, which develops numerous studies seeking an improvement in production efficiency and reduced environmental impacts caused by the planting. However, the study of soil samples, in plantation areas, demands results about the content and structural forms of organic matter (OM). Also, the soil carbon stocks depend on the type of management. Our goal is to study OM of soil samples from four sugar cane management systems: (i) unburned cane harvest, (ii) preharvest burned, (iii) addition of sugarcane bagasse ash and (iv) addition of residue from the extraction of sucrose, using Laser Induced Fluorescence Spectroscopy of solid state. All the emission spectra were acquired using the system called LIFS-405, which consists of a diode laser Coherent, model cube with excitation at 405 nm, maximum output power of 50mJ and a mini-spectrometer, Ocean Optics USB2000-high sensitivity, with range of 194-894 nm and a fiber-optic bundle design (six excitation fibers in a circular path and one central fiber the collect the fluorescence). In this work, we will present the preliminary results evolving the humification index (HLIFS) of soil OM and total carbon amount (TC) for the different types of management. HLIFS shows a close correlation with the humification index of humic acid in solution obtained by means 2D conventional fluorescence spectroscopy.

Full Text Available BACKGROUND: The cane toad, Bufo (Chaunus marinus, is one of the most notorious vertebrate pests introduced into Australia over the last 200 years and, so far, efforts to identify a naturally occurring B. marinus-specific pathogen for use as a biological control agent have been unsuccessful. We explored an alternative approach that entailed genetically modifying a pathogen with broad host specificity so that it no longer caused disease, but carried a gene to disrupt the cane toad life cycle in a species specific manner. METHODOLOGY/PRINCIPAL FINDINGS: The adult beta globin gene was selected as the model gene for proof of concept of autoimmunity as a biocontrol method for cane toads. A previous report showed injection of bullfrog tadpoles with adult beta globin resulted in an alteration in the form of beta globin expressed in metamorphs as well as reduced survival. In B. marinus we established for the first time that the switch from tadpole to adult globin exists. The effect of injecting B. marinus tadpoles with purified recombinant adult globin protein was then assessed using behavioural (swim speed in tadpoles and jump length in metamorphs, developmental (time to metamorphosis, weight and length at various developmental stages, protein profile of adult globin and genetic (adult globin mRNA levels measures. However, we were unable to detect any differences between treated and control animals. Further, globin delivery using Bohle iridovirus, an Australian ranavirus isolate belonging to the Iridovirus family, did not reduce the survival of metamorphs or alter the form of beta globin expressed in metamorphs. CONCLUSIONS/SIGNIFICANCE: While we were able to show for the first time that the switch from tadpole to adult globin does occur in B. marinus, we were not able to induce autoimmunity and disrupt metamorphosis. The short development time of B. marinus tadpoles may preclude this approach.

Towards an Agro-Industrial Ecology: A review of nutrient flow modelling and assessment tools in agro-food systems at the local scale.

2016-02-01

Improvement in nutrient recycling in agriculture is essential to maintain food production while minimising nutrient pollution of the environment. For this purpose, understanding and modelling nutrient cycles in food and related agro-industrial systems is a crucial task. Although nutrient management has been addressed at the plot and farm scales for many years now in the agricultural sciences, there is a need to upscale these approaches to capture the additional drivers of nutrient cycles that may occur at the local, i.e. district, scale. Industrial ecology principles provide sound bases to analyse nutrient cycling in complex systems. However, since agro-food social-ecological systems have specific ecological and social dimensions, we argue that a new field, referred to as "Agro-Industrial Ecology", is needed to study these systems. In this paper, we review the literature on nutrient cycling in complex social-ecological systems that can provide a basis for Agro-Industrial Ecology. We identify and describe three major approaches: Environmental Assessment tools, Stock and Flow Analysis methods and Agent-based models. We then discuss their advantages and drawbacks for assessing and modelling nutrient cycles in agro-food systems in terms of their purpose and scope, object representation and time-spatial dynamics. We finally argue that combining stock-flow methods with both agent-based models and environmental impact assessment tools is a promising way to analyse the role of economic agents on nutrient flows and losses and to explore scenarios that better close the nutrient cycles at the local scale.

Modelling the costs of energy crops. A case study of US corn and Brazilian sugar cane

International Nuclear Information System (INIS)

Mejean, Aurelie; Hope, Chris

2010-01-01

High crude oil prices, uncertainties about the consequences of climate change and the eventual decline of conventional oil production raise the prospects of alternative fuels, such as biofuels. This paper describes a simple probabilistic model of the costs of energy crops, drawing on the user's degree of belief about a series of parameters as an input. This forward-looking analysis quantifies the effects of production constraints and experience on the costs of corn and sugar cane, which can then be converted to bioethanol. Land is a limited and heterogeneous resource: the crop cost model builds on the marginal land suitability, which is assumed to decrease as more land is taken into production, driving down the marginal crop yield. Also, the maximum achievable yield is increased over time by technological change, while the yield gap between the actual yield and the maximum yield decreases through improved management practices. The results show large uncertainties in the future costs of producing corn and sugar cane, with a 90% confidence interval of 2.9-7.2$/GJ in 2030 for marginal corn costs, and 1.5-2.5$/GJ in 2030 for marginal sugar cane costs. The influence of each parameter on these supply costs is examined. (author)

Including sugar cane in the agro-ecosystem model ORCHIDEE-STICS

Science.gov (United States)

Valade, A.; Vuichard, N.; Ciais, P.; Viovy, N.

With 4 million ha currently grown for ethanol in Brazil only, approximately half the global bioethanol production in 2005 (Smeets 2008), and a devoted land area expected to expand globally in the years to come, sugar cane is at the heart of the biofuel debate. Indeed, ethanol made from biomass is currently the most widespread option for alternative transportation fuels. It was originally promoted as a carbon neutral energy resource that could bring energy independence to countries and local opportunities to farmers, until attention was drawn to its environmental and socio-economical drawbacks. It is still not clear to which extent it is a solution or a contributor to climate change mitigation. Dynamic Global Vegetation models can help address these issues and quantify the potential impacts of biofuels on ecosystems at scales ranging from on-site to global. The global agro-ecosystem model ORCHIDEE describes water, carbon and energy exchanges at the soil-atmosphere interface for a limited number of natural and agricultural vegetation types. In order to integrate agricultural management to the simulations and to capture more accurately the specificity of crops' phenology, ORCHIDEE has been coupled with the agronomical model STICS. The resulting crop-oriented vegetation model ORCHIDEE-STICS has been used so far to simulate temperate crops such as wheat, corn and soybean. As a generic ecosystem model, each grid cell can include several vegetation types with their own phenology and management practices, making it suitable to spatial simulations. Here, ORCHIDEE-STICS is altered to include sugar cane as a new agricultural Plant functional Type, implemented and parametrized using the STICS approach. An on-site calibration and validation is then performed based on biomass and flux chamber measurements in several sites in Australia and variables such as LAI, dry weight, heat fluxes and respiration are used to evaluate the ability of the model to simulate the specific

The cane palm, Chrysalidocarpus lutescens is one among the plant material of the export industries in Sri Lanka. The export quality of C. lutescens was declined due to the repeated occurrence of a leaf spot caused by Helminthosporium. Widespread occurrence of the leaf spot affected the cane palm production and succumb it to a huge setback in the floriculture industry in Sri Lanka. Being an export industry eco-friendly means of disease control was the prime focus for a better management of such vulnerable disease. Trichoderma is a potential bio agent, which has definite role in suppressing the inoculum of Helminthosporium sp. This study aims to evaluate the efficacy of Trichoderma species to control naturally established leaf spot in cane palm under field conditions. Three isolates of T. viride and two isolates of T. harzianum were evaluated. All the Trichoderma species performed significantly in reducing the disease incidence. T. viride + T. harzianum combination (1 x 10(10) cfu/ml) was the best compared to chemical in decreasing the mean disease severity index and improving the frequency of healthy plants. The colour of the leaves regained due to the application of Trichoderma sp. The results revealed that leaf spot incidence was lowered significantly in cane palms treated with Trichoderma species followed by treatment with combination of Trichoderma sp. and fungicides. The fungicide mixture (hexaconozole 50 g/l + Isoprothiolane 400 g/l) failed to lower the disease incidence and had no effect in suppressing the inocula of Helminthosporium, although recommended. Mixing of Trichoderma species with fungicide did not exhibit any additive effect. The combination of different species of Trichoderma would target species of Helminthosporium that exist as a complex group under field conditions. The results also proved that the existence of heterogeneity in Helminthosporium that could be tackled and effectively controlled by a combination of different species of the bio

Sugar-cane stalks, 2.0 cm long, were used as a support for yeast immobilization envisaging ethanol production. The assays were conducted in 38.5 L fermenters containing a bed of stalks with 50% porosity. The operational stability of the immobilized yeast, the efficiency and stability of the process, as well as the best dilution rate were evaluated. Molasses from demerara sugar production was used in the medium formulation. It was diluted to obtain 111.75 {+-} 1.51 g/L without any further treatment. Sulfuric acid was used to adjust the pH value to around 4.2. Every two days Kamoran HJ (10 ppm) or with a mixture containing penicillin (10 ppm) and tetracycline (10 ppm), was added to the medium. Ethanol yield and efficiency were 29.64 g/L.h and 86.40%, respectively, and the total reducing sugars conversion was 74.61% at a dilution rate of 0.83 h{sup -1}. The yeast-stalk system was shown to be stable for over a 60 day period at extremely variable dilution rates ranging from 0.05 h{sup -1} to 3.00 h{sup -1}. The concentration of immobilized cell reached around 109 cells/gram of dry sugar-cane stalk when the fermenter was operating at the highest dilution rate (3.00 h{sup -1}). (author)

Increasing accessibility to the blind of virtual environments, using a virtual mobility aid based on the "EyeCane": feasibility study.

Directory of Open Access Journals (Sweden)

Shachar Maidenbaum

Full Text Available Virtual worlds and environments are becoming an increasingly central part of our lives, yet they are still far from accessible to the blind. This is especially unfortunate as such environments hold great potential for them for uses such as social interaction, online education and especially for use with familiarizing the visually impaired user with a real environment virtually from the comfort and safety of his own home before visiting it in the real world. We have implemented a simple algorithm to improve this situation using single-point depth information, enabling the blind to use a virtual cane, modeled on the "EyeCane" electronic travel aid, within any virtual environment with minimal pre-processing. Use of the Virtual-EyeCane, enables this experience to potentially be later used in real world environments with identical stimuli to those from the virtual environment. We show the fast-learned practical use of this algorithm for navigation in simple environments.

The consumption of electricity in Brazil and mainly in the State of Sao Paulo is increasing gradually. On the other hand, the hydraulic potential is practically exhausted and the government has no resources for such new investments. One solution is the construction of thermo electrical plants with the use of the natural gas and sugar cane bagasse. The natural gas has the advantage of being available in great amount and less pollutant. And the sugar cane bagasse, besides being a by-product of low value, does not cause a global pollution. The work consists of the determination of the best option considering criterion of minimum cost for kWh of energy produced. For such, thermo economic analysis with electricity and steam production costs evaluation in exergetic basis, was accomplished. In the evaluations the consumption of natural gas and the costs of the sugar cane bagasse were varied. The results show that the cogeneration plant with combined cycle using natural gas and burning sugar cane bagasse in the recovery boiler presents the smallest cost of electricity and steam generation (even not being the cycle with larger exergetic efficiency). On the other hand, for a natural gas cost of 140 US$/t and a cost of sugar cane bagasse superior to 10,50 US$/t the cogeneration plant with combined cycle using only natural gas (and, therefore not burning or gasifying sugar cane bagasse) presented the smallest cost of electricity and steam generation.

Engineering and economic analysis for the utilization of geothermal fluids in a cane sugar processing plant. Final report

Energy Technology Data Exchange (ETDEWEB)

Humme, J.T.; Tanaka, M.T.; Yokota, M.H.; Furumoto, A.S.

1979-07-01

The purpose of this study was to determine the feasibility of geothermal resource utilization at the Puna Sugar Company cane sugar processing plant, located in Keaau, Hawaii. A proposed well site area was selected based on data from surface exploratory surveys. The liquid dominated well flow enters a binary thermal arrangement, which results in an acceptable quality steam for process use. Hydrogen sulfide in the well gases is incinerated, leaving sulfur dioxide in the waste gases. The sulfur dioxide in turn is recovered and used in the cane juice processing at the sugar factory. The clean geothermal steam from the binary system can be used directly for process requirements. It replaces steam generated by the firing of the waste fibrous product from cane sugar processing. The waste product, called bagasse, has a number of alternative uses, but an evaluation clearly indicated it should continue to be employed for steam generation. This steam, no longer required for process demands, can be directed to increased electric power generation. Revenues gained by the sale of this power to the utility, in addition to other savings developed through the utilization of geothermal energy, can offset the costs associated with hydrothermal utilization.

Full Text Available The sustainability of family farming properties goes through several stages, and can refer to the diversification of crops and agro-industrialization of primary products as two of them. To the extent that the farmer gets only deliver primary production to another agent in the production chain, it happens to come across challenges and barriers that previously did not know. Cooperatives of farmers present as an efficient alternative to assist producers in overcoming these difficulties. In this context it has been the Information and Communication Technologies (ICTs as tools and applications to creatively face one of the main bottlenecks of family agroindustrialization: marketing. The objective of this study was to contextualize the limits and potential of the use of ICT in organizational management, marketing, communication and marketing in a cooperative. Therefore, there was a case study of exploratory and qualitative, through participant observation and semi-structured questionnaire. The cooperative in question was using ICTs aiming perform tasks of daily life in a fast and effective way. However, the cooperative agribusinesses, there was a greater fragility of farmers, especially the dependence of children for the use of ICT, lack of commitment, dedication and habit. The managers of the cooperative have endeavored to improve the use of  ICT as well as to expand the use of these tools by their members, despite the difficulties faced, aiming not only better organization, but also reduced costs and increased marketing of the products.

Formation of Polyphenol-Denatured Protein Flocs in Alcohol Beverages Sweetened with Refined Cane Sugars.

Science.gov (United States)

Eggleston, Gillian; Triplett, Alexa

2017-11-08

The sporadic appearance of floc from refined, white cane sugars in alcohol beverages remains a technical problem for both beverage manufacturers and sugar refiners. Cane invert sugars mixed with 60% pure alcohol and water increased light scattering by up to ∼1000-fold. Insoluble and soluble starch, fat, inorganic ash, oligosaccharides, Brix, and pH were not involved in the prevailing floc-formation mechanism. Strong polynomial correlations existed between the haze floc and indicator values (IVs) (color at 420 nm pH 9.0/color at pH 4.0-an indirect measure of polyphenolic and flavonoid colorants) (R 2 = 0.815) and protein (R 2 = 0.819) content of the invert sugars. Ethanol-induced denaturation of the protein exposed hydrophobic polyphenol-binding sites that were further exposed when heated to 80 °C. A tentative mechanism for floc formation was advanced by molecular probing with a haze (floc) active protein and polyphenol as well as polar, nonpolar, and ionic solvents.

Full Text Available This study aims at assessing the determinants of variations in the production of sugar cane in Southeast and Midwest of the Brazil, between 1990 and 2009, measuring the effects area, productivity and composition. The theoretical framework consists of the conceptualization of the modernization of agriculture and the description of the theory of induced innovation. The empirical analysis is based on the work of the Shift-Share model, also known as a differential structure. In the results from 1990 to 2009 (total period, there is the hypothesis of the higher average yield of sugarcane in the Southeast and of the pattern of growth production by area in the Midwest. On the other hand, in the period 2005 to 2009, where the two regions in question had the highest growth rates of production of sugar cane, the composition effect revealed the most significant values, showing that the expansion of sugarcane production has occurred in these regions, mainly by substituting other crops by land less profitable.

The present study describes the screening of different agroindustrial byproducts for enhanced production of alkaline protease by a wild and EMS induced mutant strain of Bacillus subtilis IH-72EMS8. During submerged fermentation, different agro-industrial byproducts were tested which include defatted seed meals of rape, guar, sunflower, gluten, cotton, soybean, and gram. In addition to these meals, rice bran, wheat bran, and wheat flour were also evaluated for protease production. Of all the byproducts tested, soybean meal at a concentration of 20 g/L gave maximum production of the enzyme, that is, 5.74  ±  0.26 U/mL from wild and 11.28  ±  0.45 U/mL from mutant strain, during submerged fermentation. Different mesh sizes (coarse, medium, and fine) of the soybean meal were also evaluated, and a finely ground soybean meal (fine mesh) was found to be the best. In addition to the defatted seed meals, their alkali extracts were also tested for the production of alkaline protease by Bacillus subtilis, but these were proved nonsignificant for enhanced production of the enzyme. The production of the enzyme was also studied in solid state fermentation, and different agro-industrial byproducts were also evaluated for enzyme production. Wheat bran partially replaced with guar meal was found as the best substrate for maximum enzyme production under solid state fermentation conditions. PMID:24294129

Sugar cane bagasse was submitted to ethanol organosolv pre-treatment using a 50 L pilot scale reactor. The influence of catalyst type (H{sub 2}SO{sub 4} or NaOH), catalyst concentration (1.25-1.50% w/w on dry fiber) and process time (60-90 min) on total solid recovery and solid composition (glucan, xylan and lignin contents) was evaluated by performing a 2{sup 3} full factorial experimental design. Pretreated sugar cane bagasse was further submitted to enzymatic hydrolysis using a commercial enzyme complex formed by cellulases and {beta}-glucosidases. Glucose concentration in the hydrolysates and glucose yield referred to initial raw material (g glucose/100 g sugar cane bagasse) were used to select the best operational conditions. Concerning the enzymatic hydrolysis, the resulting glucose concentration was found to be dependent on xylan contents of the pretreated material. The modelling equations for glucose concentration and glucose yield as a function of the pre-treatment variables and the statistical analysis are also discussed in this work. (author)

Full Text Available ABSTRACT Objective: To evaluate the effects of exposure to emissions from sugar cane burning on inflammatory mechanisms in tissues of the trachea and lung parenchyma in Wistar rats after different periods of exposure. Methods: This was an experimental open randomized study. The animals were divided into four groups: a control group (CG underwent standard laboratory conditions, and three experimental groups were exposed to emissions from sugar cane burning over different periods of time, in days-1 (EG1, 7 (EG7, and 21 (EG21. After euthanasia with 200 mg/kg of ketamine/xylazine, fragments of trachea and lung were collected and fixed in 10% formalin. Histological analyses were performed with H&E and picrosirius red staining. Results: No inflammatory infiltrates were found in the tissues of CG rats. The histological examination of tissues of the trachea and lung parenchyma revealed that the inflammatory process was significantly more intense in EG7 than in the CG (p < 0.05 and p < 0.01, respectively. In comparison with the CG and EG1, angiogenesis in the lung parenchyma and collagen deposition in tracheal tissues were significantly greater only in EG21 (p < 0.001 and p < 0.01, respectively. Conclusions: In this sample, emissions from sugar cane burning induced acute focal and diffuse inflammation in the lamina propria of tracheal tissues, with no loss of ciliated epithelial tissue. In the lung parenchyma of the animals in the experimental groups, there was interstitial and alveolar edema, together with polymorphonuclear cell infiltrates.

Full Text Available The search of the biotechnological ways to the integral use of the wastes generated by the coffee and citric agroindustries, is a current problem. The biotransformation of coffee pulp and orange mesocarp during aerobic and anoxic fermentation with the pectinolític yeast Kluyveromyces marxianus CCEBI 2011 was studied in this research. It was found that coffee pulp is a better substrate to yeast growth, which was evidenced throughout a better conversion of the carbon and energy source. The yeast used in 24 h the reducing and neutral sugars from substrates efficiently, either under aerobic or oxygen-limited cultures. The excretion of the polygalacturonase enzyme by the yeast lead to the increasing in the pectic substances extraction, which reached the 225 % and 33 % for coffee pulp and orange mesocarp, respectively, compared with the amounts which were extracted during substrates sterilization. The enzyme production by the microorganism presented not significantly differences in relation to the substrate used, but the contrary occurred with respect to glucose concentration in the medium. These results point to the promissory use of the K. marxianus CCEBI 2011 yeast strain in the valorization of pectin-rich agricultural wastes by means of their conversion in potential plant elicitors and prebiotics oligogalacturonides-based.

Toad skins and venom glandular secretions have been widely used for centuries in traditional Chinese and Japanese medicine for the treatment of various ailments such as cancer, sores, toothache, local inflammation and pain. The active chemical constituents from traditional oriental medicines have demonstrated potential in the development of effective therapeutic pharmaceuticals. Our primary focus in this research was to identify and characterise 'active' compounds or groups of compounds for their potential as neuropsychiatric disorder therapeutics. For this aim, we utilised a variety of solvents, i.e., the aqueous, 60% ethanol (aqueous) and acetic acid (aq) (at two different pHs) for extractions of Australian cane toad skins to identify chemical constituents. The identification of compounds was carried out using HPLC-ESI-Q-TOF-MS/MS based on the accurate mass measurement for molecular ions and MS/MS analysis, whereby accurate mass pseudo-molecular ions and characteristic fragment ions were compared to published reference data, including mass bank and NIST. As a result, we have to date identified 42 major constituents including alkaloids, amino acids, bufadienolides, fatty acids, nucleobases, nucleosides and vitamins mostly from the aqueous and 60% ethanol extracts. Of the 42 constituents identified, 29 were found in the aqueous extract, 35 were found in the ethanol (aq) extract and only 10 in the pH 1.78 acetic acid extract and 11 in the pH 2.17 acetic acid extract of the cane toad skins. Therefore, the aqueous and 60% ethanolic extracts present the greatest potential for ongoing development in our assays. There have been no previous reports on the identification of many of the constituents we have here identified in Australian cane toad skins. These findings, while somewhat consistent with findings in toad skins in other countries, identifies the presence of potential bioactive constituents. Our results showed that HPLC-ESI-Q-TOF-MS/MS is an effective method to

2005-01-01

It was performed in this study a survey on the quality of commercial sugar cane spirits. The problems that the cachaca faces, mainly in the international market, are due to its low quality and to the lack of standardization of the drink. Commercial samples of sugar cane spirits were analyzed according to the standards of the identity and quality established by the Brazilian law (physical-chemical and chromatographic analyses). There was a great variation in the concentration of the compounds, except in alcoholic content, indicating that the Brazilian sugar cane spirit presents a great variability in the chemical composition among the brands. Among the 94 analyzed brands, 48% did not answer at least one of the standards. Another study performed was the influence of oak wood and the gamma radiation on the sugar cane spirits aging. The aging or maturation process of the drink improves the sensorial characteristics of the product, making it a qualified drink with a higher economical value. The traditional maturation method of the drinks is their interaction with the wood, but the irradiation can accelerate this aging process up. The sugar cane spirit and the oak barrels with 20 liters capacity were subjected to gamma irradiation treatments (150 Gy). Physical-chemical and chromatographic analyses were performed constantly for 390 days during the drink aging period. The sugar cane spirit and barrel irradiation didn't change most of volatile components of the same type coefficient such as volatile acidity, esters, superior alcohols and furfural during the 390 days. There are evidences, however, that some components parameters like aldehydes, tannin, color and copper concentration are in some way influenced, resulting in partial acceleration of the aging or maturing process. At the end of the aging period, a sensorial analysis was made using 30 non-trained people who tasted the drink. The aging process acceleration was confirmed by the sensorial evaluation, where the sugar

Frias, Moises; Villar-Cocina, E.; Valencia-Morales, E.

2007-01-01

This paper reports on the influence of calcining temperature (800 and 1000 deg. C) on the pozzolanic activation of sugar cane straw (SCS). The reaction kinetics of SCS ash-lime mixtures were inferred from physicochemical characteristics (X-ray diffraction patterns and thermogravimetry analysis. The fitting of a kinetic-diffusive model to the experimental data (fixed lime versus time) allowed the computing of the kinetic parameters (reaction rate constant) of the pozzolanic reaction. Results obtained confirm that the sugar cane straw ash (SCSA) calcined at 800 and 1000 deg. C have properties indicative of very high pozzolanic activity. No influence of calcining temperature on the pozzolanic activity was observed. Also, no crystalline compounds during the pozzolanic reaction were identified up to 90 days of reaction. Environmental durability and strength of the consequential mortars remain to be assessed

Aquatic organisms, such as microalgae (Chlorella, Arthrospira (Spirulina), Tetrasselmis, Dunalliela etc.) and duckweed (Lemna spp., Wolffia spp. etc.) are a potential source for the production of protein-rich biomass and for numerous other high-value compounds (fatty acids, pigments, vitamins etc.). Their cultivation using agro-industrial wastes and wastewater (WaW) is of particular interest in the context of a circular economy, not only for recycling valuable nutrients but also for reducing the requirements for fresh water for the production of biomass. Recovery and recycling of nutrients is an unavoidable long-term approach for securing future food and feed production. Agro-industrial WaW are rich in nutrients and have been widely considered as a potential nutrient source for the cultivation of microalgae/duckweed. However, they commonly contain various hazardous contaminants, which could potentially taint the produced biomass, raising various concerns about the safety of their consumption. Herein, an overview of the most important contaminants, including heavy metals and metalloids, pathogens (bacteria, viruses, parasites etc.), and xenobiotics (hormones, antibiotics, parasiticides etc.) is given. It is concluded that pretreatment and processing of WaW is a requisite step for the removal of several contaminants. Among the various technologies, anaerobic digestion (AD) is widely used in practice and offers a technologically mature approach for WaW treatment. During AD, various organic and biological contaminants are significantly removed. Further removal of contaminants could be achieved by post-treatment and processing of digestates (solid/liquid separation, dilution etc.) to further decrease the concentration of contaminants. Moreover, during cultivation an additional removal may occur through various mechanisms, such as precipitation, degradation, and biotransformation. Since many jurisdictions regulate the presence of various contaminants in feed or food

Anaerobic digestion of agro-industrial waste is of significant interest in order to facilitate a sustainable development of energy supply. Using of material and energy potentials of agro-industrial waste, in the framework of technical, economic, and ecological possibilities, contributes in increasing the share of energy generated from renewable energy sources. The paper deals with the benefits arising from the utilization of biogas produced by co-digestion of whey and cow manure. The advantages of this process are the profitability of the plant and the convenience in realizing an anaerobic digestion plant to produce biogas that is enabled by the benefits from the sale of electric energy at favorable prices. Economic aspects are related to the capital cost (€ 2,250,000) of anaerobic digestion treatment in a biogas plant with a 300 kW power and 510 kW heating unit in a medium size farm (450 livestock units). Considering the optimum biogas yield of 20.7 dm(3) kg(-1) of wet substrate and methane content in the biogas obtained of 79%, the anaerobic process results in a daily methane production of 2,500 kg, with the maximum power generation of 2,160,000 kWh y(-1) and heat generation of 2,400,000 kWh y(-1) The net present value (NPV), internal rate of return (IRR) and payback period for implementation of profitable anaerobic digestion process is evaluated. Ecological aspects related to carbon dioxide (CO2) and methane (CH4) emission reduction are assessed. © The Author(s) 2014.

The exploitation of common agroindustrial wastes to produce important industrial bioproducts was examined during a research study in which the solvent glycol was bioproduced for industrial applications. The preliminary results of fermentation on starch hydrolysate, sugar beet molasses and cheese whey by microorganisms were presented. Currently, 2,3-butanediol synthesizes by chemical pathways even though its biotechnological production from industrial wastes has two interesting possibilities. These include the low production costs of fermentation to obtain a compound with a huge market, plus the reduced environmental impact of waste pollution by biodegradation. In this study, pure cultures of Enterobacter aerogenes were used in a stirred batch reactor under micro-aerobic conditions. In order to determine the optimal working conditions for bacterial production of 2,3-butanediol on a glucose solution, several batch fermentations were conducted at different pH levels, temperatures and substrate concentrations. It was determined that the final glycol concentration increases with the increase in initial substrate composition even when the product yield decreases. 14 refs., 1 tab., 4 figs.

The reserves of fossil-based fuels, which currently seem sufficient to meet the global demands, is inevitably on the verge of exhaustion. Contemporary raw material for alternate fuel like biodiesel is usually edible plant commodity oils, whose increasing public consumption rate raises the need of finding a non-edible and fungible alternate oil source. In this quest, single cell oils (SCO) from oleaginous yeasts and fungi can provide a sustainable alternate of not only functional but also valuable (polyunsaturated fatty acids (PUFA)-rich) lipids. Researches are been increasingly driven towards increasing the SCO yield in order to realize its commercial importance. However, bulk requirement of expensive synthetic carbon substrate, which inflates the overall SCO production cost, is the major limitation towards complete acceptance of this technology. Even though substrate cost minimization could make the SCO production profitable is uncertain, it is still essential to identify suitable cheap and abundant substrates in an attempt to potentially reduce the overall process economy. One of the most sought-after in-expensive carbon reservoirs, agro-industrial wastes, can be an attractive replacement to expensive synthetic carbon substrates in this regard. The present review assess these possibilities referring to the current experimental investigations on oleaginous yeasts, and fungi reported for conversion of agro-industrial feedstocks into triacylglycerols (TAGs) and PUFA-rich lipids. Multiple associated factors regulating lipid accumulation utilizing such substrates and impeding challenges has been analyzed. The review infers that production of bulk oil in combination to high-value fatty acids, co-production strategies for SCO and different microbial metabolites, and reutilization and value addition to spent wastes could possibly leverage the high operating costs and help in commencing a successful biorefinery. Rigorous research is nevertheless required whether it is

Tools and criteria for Cost-Benefit Analysis (ACB) of energy saving in bioclimatic designs (DB) are presented, for which a reference project is established. Based on the traditional design of air conditioning of a building and with the support of this one, the estimation of costs and benefits of the same building is made; but with passive systems. The tools used consider related resources such as time and money. Criteria are used such as: Present value (VP), Equivalent Annual Cost (EAC) and the Cost of the conserved Energy (CEC). The costs related to the construction, maintenance and operation of the design are taken into consideration. The differences between the design of reference and the Bioclimatic Design, established from the application of these criteria, allow evaluating the economic margin as far as operation and maintenance. Finally, the cost of the conserved energy of the bioclimatic measures is evaluated as an initiative for energy saving and calculates the present value from them in all of the period of useful life of the bioclimatic design.

Full Text Available High-altitude regions of southern Brazil, located above 900 m above sea level, the cordon training with spur pruning is widely used because of easier application. In these regions, Chardonnay wine grape shows potential to produce quality wines, however, in commercial vineyards, the training system used has not provided productivities that makes economically viable the cultivation of this variety. Given this, the present study aimed to evaluate the effect of different cane-pruning systems on the vegetative, productive and enological potential of Chardonnay grapevines grown in the high-altitude region of Southern Brazil. The experiment was conducted in a commercial Chardonnay vineyard, located in São Joaquim – Santa Catarina State (28o17 ′39”S and 49∘ 55′56” W, to 1230 m a.s.l during 2015 and 2016 vintages. Chardonnay vines (grafted on 1103 Paulsen were planted in 2010, with a 3.0 m (row × 1.0 m (vine spacing. The treatments consisted of different cane-pruning systems: Cordon spur-pruning (control; Sylvoz; Cazenave; Capovolto; single Guyot and double Guyot. Pruning was performed in August of each year when the buds were in the green tip developmental stage. Data was analyzed by Scott Knott test (p < 0.05 following a randomized block design with four replicates, each consisting of 12 vines per plot. We observed higher yield in the Cazenave and double Guyot training system with three and two more tons of grapes than spur-pruning respectively. The bud fertility was higher in plants trained in double Guyot. Vines spur-pruned showed higher relation of leaf area: production, with values above 100 cm2 g−1 grape at 2016 vintage. Commercial maturity of grapes (soluble solids, acidity and polyphenols did not differ among training systems studied. The results suggest that cane-pruning systems could be an alternative to increase production efficiency of Chardonnay in high-altitude region of southern Brazil.

In Valle del Cauca, south-west Colombia, surface and ground waters are used for sugar cane irrigation at a rate of 100 m3 of water per tonne of sugar produced. In addition large quantities of artificial fertilizers and pesticides are used to grow the crop. Preliminary experiments were undertaken to determine the feasibility of using effluents from the Cañaveralejo primary wastewater treatment plant in Cali. Sugar cane variety CC 8592 was planted in 18 box plots, each 0.5 m2. Six were irrigated with conventional primary effluent, six with chemically enhanced primary effluent and six with groundwater. For each set of six box plots, three contained local soil and three a 50:50 mixture of sand and rice husks. The three irrigation waters were monitored for 12 months, and immediately after harvest the sugar content of the sugar cane juice determined. All physico-chemical quality parameters for the three irrigation waters were lower than the FAO guideline values for irrigation water quality; on the basis of their sodium absorption ratios and electrical conductivity values, both wastewater effluents were in the USDA low-to-medium risk category C2S1. There was no difference in the sugar content of the cane juice irrigated with the three waters. However, the microbiological quality (E. coli and helminth numbers) of the two effluents did not meet the WHO guidelines and therefore additional human exposure control measures are required in order to minimize any resulting adverse health risks to those working in the wastewater-irrigated fields.

Orientation and mobility training (O&M-training) in using an identification cane, also called symbol cane, is provided to people with low vision to facilitate independent participation in the community. In The Netherlands this training is mainly practice-based because a standardised and validly evaluated O&M-training in using the identification cane is lacking. Recently a standardised O&M-training in using the identification cane was developed. This training consists of two face-to-face sessions and one telephone session during which, in addition to usual care, the client's needs regarding mobility are prioritised, and cognitive restructuring techniques, action planning and contracting are applied to facilitate the use of the cane. This paper presents the design of a randomised controlled trial aimed to evaluate this standardised O&M-training in using the identification cane in older adults with low vision. A parallel group randomised controlled trial was designed to compare the standardised O&M-training with usual care, i.e. the O&M-training commonly provided by the mobility trainer. Community-dwelling older people who ask for support at a rehabilitation centre for people with visual impairment and who are likely to receive an O&M-training in using the identification cane are included in the trial (N = 190). The primary outcomes of the effect evaluation are ADL self care and visual functioning with respect to distance activities and mobility. Secondary outcomes include quality of life, feelings of anxiety, symptoms of depression, fear of falling, and falls history. Data for the effect evaluation are collected by means of telephone interviews at baseline, and at 5 and 17 weeks after the start of the O&M-training. In addition to an effect evaluation, a process evaluation to study the feasibility of the O&M-training is carried out. The screening procedure for eligible participants started in November 2007 and will continue until October 2009. Preliminary findings

Full Text Available A cana-de-açúcar está entre as culturas que apresenta larga escala de adaptações às condições climáticas, sendo utilizada para a fabricação de diversos produtos. Dentre os produtos derivados da cana-de-açúcar, o melado é tido popularmente como um alimento rico em ferro. Este trabalho objetivou conhecer a concentração de alguns minerais em melados comerciais e em melados preparados com equipamentos de aço inoxidável. Ao todo foram 20 amostras, 10 de cada tipo. As amostras foram preparadas para análise por oxidação da matéria orgânica por via úmida e os teores de Ca, Mg, Cu, Mn, Zn e Fe foram determinados por espectroscopia de absorção atômica, Na e K por fotometria de chama e P por colorimetria. Concluiu-se, com este trabalho, que os teores médios dos minerais Fe, P, Na e Mg foram significativamente mais elevados nos melados comerciais do que nos melados feitos com equipamentos inox. O contrário foi encontrado para o mineral cálcio, que apresentou teor mais elevado nos melados feitos no laboratório, mas condizentes com os teores encontrados nos caldos de cana. Não houve diferença significativa nos teores dos demais minerais.Sugar cane is an easily adaptable crop to diverse climate conditions, and it is used in the manufacturing of many different products. Among those products is the syrup, which is popularly known to be good sources of iron. In this work, we aimed to measure the concentration of some minerals in commercial sugar cane syrup brands and syrup prepared in the laboratory using stainless steel equipment. A total of 20 samples were analyzed, 10 of commercial brands and ten prepared in the laboratory. The samples were prepared by wet-air oxidation of organic matter and the contents of Ca, Mg, Cu, Mn, Zn, and Fe were determined by atomic absorption. Na and K were determined by photometry and P by colorimetry. It was found that the mean concentration of Fe, P, Na, and Mn were higher in the commercial

Biodegradable wastes produced seasonally need an upstream storage, because of the requirement for a constant feeding of anaerobic digesters. In the present article, the potential of co-ensiling biodegradable agro-industrial waste (sugar beet leaves) and lignocellulosic agricultural residue (wheat straw) to obtain a mixture with low soluble sugar content was evaluated for long-term storage prior to anaerobic digestion. The aim is to store agro-industrial waste while pretreating lignocellulosic biomass. The dynamics of co-ensiling was evaluated in vacuum-packed bags at lab-scale during 180 days. Characterization of the reaction by-products and microbial communities showed a succession of metabolic pathways. Even though the low initial sugars content was not sufficient to lower the pH under 4.5 and avoid undesirable fermentations, the methane potential was not substantially impacted all along the experiment. No lignocellulosic damages were observed during the silage process. Overall, it was shown that co-ensiling was effective to store highly fermentable fresh waste evenly with low sugar content and offers new promising possibilities for constant long-term supply of industrial anaerobic digesters.

Full Text Available A necessidade de regulamentação no sistema agroindustrial (SAG da borracha natural no Brasil é evidente. Desde a metade do século, quando o país passou a importar esse produto, vários esforços governamentais vêm sendo definidos, objetivando o desenvolvimento sustentável do setor da produção agrícola nacional de borracha. No ano de 1997, criou-se uma política de subvenção direta à produção. Dada a estrutura desse SAG, associada à conjuntura do mercado internacional e a uma regulamentação falha do governo federal, começaram a surgir indícios de abuso de poder de mercado pela indústria pneumática instalada no país, principal consumidora do produto. Utilizando o arcabouço teórico da organização industrial, neste artigo se procurou levantar evidências nesse sentido.The need for regulation of Brazil’s natural rubber agro-industrial system (SAG is evident. Since the middle of the 20th century, when the country began importing rubber, many governmental efforts have been made to promote the sustainable development of Brazil’s natural rubber productive sector. In 1997, the Brazilian government created a direct subvention policy to assist rubber producers. Given the structure of Brazil’s SAG, the international rubber market, and imperfect regulation by the Federal Government, it would not be unexpected to find signs that Brazil’s largest natural rubber consumer, the domestic tire industry, has begun to abusively exercise its market power. Using the theoretical structure of Industrial Organization, this paper tries to show evidences of this abuse.

Alkaline deacetylation has emerged as a promising chemistry for pretreatments performed prior to enzymatic saccharification of lignocellulosic biomass. This process avoids complex pressurized reactors and opens new opportunities for lignin covalorization. In this work, we evaluate the chemical and morphological response of sugar cane bagasse and straw submitted to alkaline treatments. Alkaline solutions for deacetylation (0.4% w/w NaOH, 70 degrees C, 3 h) as well as proximal conditions (0.1-0.7% NaOH, 55-85 degrees C, 1-5 h) chosen by 23 experimental design were evaluated. The deacetylation treatment removes ~90% of the acetyl groups and 20-30% of the lignin from both bagasse and straw, while removal of ~20% of the xylan and glucan is observed in straw, but not in bagasse. Considering nanoscale structural alterations, neither cellulose cocrystallization (evaluated by X-ray diffraction) nor formation of lignin aggregates (evaluated by thermoporometric signature) are observed after the alkaline conditions, in contrast to observations after hydrothermal treatments. Furthermore, calorimetric thermoporometry as well as scanning and transmission electron microscopies show substantial introduction of nanoscale porosity and loosening of the tissue and cell wall structures, indicating desirable mechanical weakening and gains in enzyme accessibility. These results provide fundamental and practical knowledge for biorefineries based on alkaline deacetylation of sugar cane bagasse and straw.

Development and application of a thermophysical property model for cane fiberboard subjected to high temperatures

International Nuclear Information System (INIS)

Hensel, S.J.; Gromada, R.J.

1994-01-01

A thermophysical property model has been developed to analytically determine the thermal response of cane fiberboard when exposed to temperatures and heat fluxes associated with the 10 CFR 71 hypothetical accident condition (HAC) and associated post fire cooling. The complete model was developed from high temperature cane fiberboard 1-D test results and consists of heating and cooling sub-models. The heating property model accounts for the enhanced heat transfer of the hot gases in the fiberboard, the loss of energy via venting, and the loss of mass from venting during the heating portion of the test. The cooling property model accounts for the degraded material effects and the continued heat transfer associated with the hot gases after removal of the external heating source. Agreement between the test results of a four inch thick fiberboard sample with the analytical application of the complete property model is quite good and will be presented. A comparison of analysis results and furnace test data for the 9966 package suggests that the property model sufficiently accounts for the heat transfer in an actual package

Sodium-alginate immobilized yeast was employed to produce ethanol continuously using cane molasses as a carbon source in an immobilized cell reactor (ICR). The immobilization of Saccharomyces cerevisiae was performed by entrapment of the cell cultured media harvested at exponential growth phase (16 h) with 3% sodium alginate. During the initial stage of operation, the ICR was loaded with fresh beads of mean diameter of 5.01 mm. The ethanol production was affected by the concentration of the cane molasses (50, 100 and 150 g/l), dilution rates (0.064, 0.096, 0.144 and 0.192 h{sup -1}) and hydraulic retention time (5.21, 6.94, 10.42 and 15.63 h) of the media. The pH of the feed medium was set at 4.5 and the fermentation was carried out at an ambient temperature. The maximum ethanol production, theoretical yield (Y{sub E/S}), volumetric ethanol productivity (Q{sub P}) and total sugar consumption was 19.15 g/l, 46.23%, 2.39 g l{sup -1} h{sup -1} and 96%, respectively.

Tuberculosis (TB) remains one of the leading causes of morbidity and mortality among indigenous peoples in Brazil, and identifying the risk factors for TB in this population secondary to specific epidemiological conditions is essential for recommending interventions aimed at disease control. This case-control study was conducted with an indigenous population between June 2009 and August 2011 in Dourados, Brazil. Tuberculosis cases reported to the national disease surveillance programme were paired with two control cases matched by age and geographic location. There were 63 cases included in this study, and the annual incidence of TB in the indigenous communities examined was 222 (95% CI, 148-321) per 100 000 inhabitants. The multivariate analysis demonstrated that the variables associated with TB infection included male gender (OR 2.6; 95% CI 1.3-5.3), not owning a home (OR 3.4; 95% CI 1.2-10.1), illiteracy (OR 2.4; 95% CI 1.1-5.0), TB contact (OR 2.4; 95% CI 1.2-4.8) and work performed in a sugar cane factory (OR 6.8; 95% CI 1.2-36.9). There is a potential relationship between exposure to sugar cane manufacturing processes and tuberculosis infection among indigenous populations.

Improvement in nutrient recycling in agriculture is essential to maintain food production while minimising nutrient pollution of the environment. For this purpose, understanding and modelling nutrient cycles in food and related agro-industrial systems is a crucial task. Although nutrient management has been addressed at the plot and farm scales for many years now in the agricultural sciences, there is a need to upscale these approaches to capture the additional drivers of nutrient cycles that may occur at the local, i.e. district, scale. Industrial ecology principles provide sound bases to analyse nutrient cycling in complex systems. However, since agro-food social-ecological systems have specific ecological and social dimensions, we argue that a new field, referred to as “Agro-Industrial Ecology”, is needed to study these systems. In this paper, we review the literature on nutrient cycling in complex social-ecological systems that can provide a basis for Agro-Industrial Ecology. We identify and describe three major approaches: Environmental Assessment tools, Stock and Flow Analysis methods and Agent-based models. We then discuss their advantages and drawbacks for assessing and modelling nutrient cycles in agro-food systems in terms of their purpose and scope, object representation and time-spatial dynamics. We finally argue that combining stock-flow methods with both agent-based models and environmental impact assessment tools is a promising way to analyse the role of economic agents on nutrient flows and losses and to explore scenarios that better close the nutrient cycles at the local scale. - Highlights: • An Agro-Industrial Ecology perspective is essential to model local agro-food systems. • We provide a classification of nutrient (N, P) models, methods and assessment tools. • We distinguished Environmental Assessment, Stock and flow and Agent-based approaches. • The pros and cons of these nutrient cycle models, methods and tools are discussed. �

The project of installation of speed variator in fossil power stations (CT's) of Comision Federal de Electricidad (CFE), as an energy saving measure, is a pilot project that began with the support of the Subdivision de Generacion, and promoted by the Energy Saving Program of the Electric Sector (PAESE), with the putting in operation of an equipment in the condensate pump of the Punta Prieta II C. T. U3. The energy saving observed was substantial, fluctuating between the 19.4% at high loads (at 90% load) and the 71.1% at low loads (at 40% load) of the generating unit. With these results, it was decided to extend the scope of the project with the installation of 6 more equipment for equal number of fossil power stations, located in 4 of the 5 Regions of Generation. The fossil power stations, selected for this stage of the project were: C. T. Felipe Carrillo Puerto U1, C.T. Lerma U4, C.T. Salamanca U1, C.T. Monterrey U6, C.T. Francisco Villa U3 and the C.T. Punta Prieta II-U1. The equipment was in operation during the first quarter of 1998, and the first results indicate an energy savings average per equipment, between 39% and 52%. The recovery of the investment fluctuates between the 48.4% and the 87.6% in less than two years of operation, with which a maximum period of recovery of 3 years is expected. The estimated potential of energy saving, considering the application of these devices in condensate pumps, feedwater pumps (where no speed variator is installed) forced draft fans, induced draft fans and gas recirculation fans, as well as circulation water pumps, of the existing Generating Power stations, ascends to an annual total of 830,000, which represents an approximate 9.4% of the National consumption of self services.

The use of agroindustry by-products (BP) for fortification of wheat bread can be an alternative to waste disposal because BP are appealing sources of dietary fiber. Moreover, it may also contribute to indirect income generation. In this study, sensory, color, and crumb structure properties of breads fortified with fiber rich fraction recovered from four types of agroindustry BP were tested, namely orange (OE), pomegranate (PE), elderberry (EE), and spent yeast (YE). Statistical models for sensory preference evaluation and correlation with color and crumb structure were developed. External preference mapping indicated consumer preferences and enabled selection of the concentrations of BP fibre-rich fraction with best acceptance, namely 7.0% EE, 2.5% OE, 5.0% PE, and 2.5% YE. Data collected from image analysis complemented sensory profile information, whereas multivariate PLS regression provided information on the relationship between "crust color" and "crumb color" and instrumental data. Regression models developed for both sensory attributes presented good fitting (R 2 Y > 0.700) and predictive ability (Q 2 > 0.500), with low RMSE. Crust and crumb a* parameters had a positive influence on "crust color" and "crumb color" models, while crust L* and b* had a negative influence. © 2017 Institute of Food Technologists®.

In order to produce sugar canes of optimum richness at the time of harvesting, it is necessary to determine the duration of the weaning period and the water requirements prior to this period. This problem was studied for a naturally grown cane with a NCo 376 cycle grown in the north of the Ivory coast. Water balances were determined using neutronic and tensiometric methods. It was thus possible to confirm the practical usefulness of tensiometers and to establish a weaning period of one month and a half and to determine a vegetation coefficient K=0.5 [fr

Full Text Available Microbial processes leading to the production of energy from vegetable biomasses and from residues of the agroindustry make possible the exploitation of widely available and renewable energy sources which can be considered at zero balance with regard to CO2 fixation and emission. These processes show a different level of technological maturity: some of them, like the production of bioethanol or biogas, are well established and diffused processes, while others, like hydrogen production, are in the phase of advanced research. Considering the future prospects, the latter process is the most promising owing to the high calorific value of hydrogen and the absence of polluting emissions when H2 is used for combustions or for the production of electricity with fuel cells. In this review, the research activities carried out, in the field of biogas and hydrogen production, by research groups belonging to the Italian Society for Agricultural, Environmental and Food Microbiology (SIMTREA are presented.

Full Text Available Abstract Background Orientation and mobility training (O&M-training in using an identification cane, also called symbol cane, is provided to people with low vision to facilitate independent participation in the community. In The Netherlands this training is mainly practice-based because a standardised and validly evaluated O&M-training in using the identification cane is lacking. Recently a standardised O&M-training in using the identification cane was developed. This training consists of two face-to-face sessions and one telephone session during which, in addition to usual care, the client's needs regarding mobility are prioritised, and cognitive restructuring techniques, action planning and contracting are applied to facilitate the use of the cane. This paper presents the design of a randomised controlled trial aimed to evaluate this standardised O&M-training in using the identification cane in older adults with low vision. Methods/design A parallel group randomised controlled trial was designed to compare the standardised O&M-training with usual care, i.e. the O&M-training commonly provided by the mobility trainer. Community-dwelling older people who ask for support at a rehabilitation centre for people with visual impairment and who are likely to receive an O&M-training in using the identification cane are included in the trial (N = 190. The primary outcomes of the effect evaluation are ADL self care and visual functioning with respect to distance activities and mobility. Secondary outcomes include quality of life, feelings of anxiety, symptoms of depression, fear of falling, and falls history. Data for the effect evaluation are collected by means of telephone interviews at baseline, and at 5 and 17 weeks after the start of the O&M-training. In addition to an effect evaluation, a process evaluation to study the feasibility of the O&M-training is carried out. Discussion The screening procedure for eligible participants started in November

Full Text Available Neste estudo, formulou-se o problema de gestão do fluxo de caixa encontrado em uma típica empresa agroindustrial como um modelo de otimização de fluxos em rede (com perdas e ganhos proposto em Golden, Liberatore e Lieberman (1979. O objetivo é maximizar o retorno dos recursos financeiros do caixa no final de um horizonte de planejamento multiperíodos e finito. Dois exemplos são estudados aplicando-se programação linear: no primeiro, o modelo original de fluxos em rede é usado para apoiar decisões operacionais de fluxo de caixa e, no segundo, o modelo é estendido para tratar de um planejamento tático de pagamentos de empréstimos. Os modelos matemáticos são resolvidos usando-se a ferramenta de otimização de um software de planilha eletrônica bem conhecido na prática de empresas. Os resultados numéricos obtidos mostram que os modelos são flexíveis e eficazes, sendo capazes de gerar soluções tão boas ou melhores do que as da tesouraria da empresa.In this study we formulate the cash flow management problem encountered in a typical agroindustrial company as a network flow optimization model (with gains and losses proposed in Golden, Liberatore e Lieberman (1979. The objective is to maximize the cash return of the financial resources at the end of a multi-period and finite planning horizon. Two examples are studied applying linear programming: in the first, the original network flow model is used to support operational cash flow decisions and in the second, the model is extended to deal with a tactical planning of loan payments. The mathematical models are solved using the optimization tool of a widely-used software spreadsheet package. The numerical results obtained show that the models are flexible and effective, being able to generate solutions, equal to or superior to the company solutions.

To achieve economically competitive biological hydrogen production, it is crucial to consider inexpensive materials such as lignocellulosic substrate residues derived from agroindustrial activities. It is possible to use (1) lignocellulosic materials without any type of pretreatment, (2) lignocellulosic materials after a pretreatment step, and (3) lignocellulosic materials hydrolysates originating from a pretreatment step followed by enzymatic hydrolysis. According to the current literature data on fermentative H2 production presented in this review, thermophilic conditions produce H2 in yields approximately 75% higher than those obtained in mesophilic conditions using untreated lignocellulosic substrates. The average H2 production from pretreated material is 3.17 ± 1.79 mmol of H2/g of substrate, which is approximately 50% higher compared with the average yield achieved using untreated materials (2.17 ± 1.84 mmol of H2/g of substrate). Biological pretreatment affords the highest average yield 4.54 ± 1.78 mmol of H2/g of substrate compared with the acid and basic pretreatment - average yields of 2.94 ± 1.85 and 2.41 ± 1.52 mmol of H2/g of substrate, respectively. The average H2 yield from hydrolysates, obtained from a pretreatment step and enzymatic hydrolysis (3.78 ± 1.92 mmol of H2/g), was lower compared with the yield of substrates pretreated by biological methods only, demonstrating that it is important to avoid the formation of inhibitors generated by chemical pretreatments. Based on this review, exploring other microorganisms and optimizing the pretreatment and hydrolysis conditions can make the use of lignocellulosic substrates a sustainable way to produce H2.

The ageing or maturing process of drink improves the sensorial characteristics of the product making it a qualified drink with higher economical value. The traditional maturing method of drinks involves their interaction with wood and irradiation can accelerate this ageing process. Sugar cane spirit and oak barrels with a 20 L capacity were treated using gamma irradiation (150 Gy). Physical-chemical and chromatographic analyses were constantly performed for 390 days during the drink ageing period. The sugar cane spirit and barrel irradiation did not change most volatile components of the same type coefficient such as volatile acidity, esters, superior alcohols and furfural throughout the 390 days. There is evidence, however, that some component parameters like aldehydes, tannin, color and copper concentration are in some way influenced resulting in partial acceleration of the ageing or maturing process. At the end of the ageing period, a sensorial analysis was made using 30 non-trained people who tasted the drink. The ageing process acceleration was confirmed by the sensorial evaluation, where the irradiated sugar cane spirit and/or barrel had higher approval regarding all parameters analyzed (scent, flavor and appearance) [pt
