Composite Panels from the Combination of Rice Husk and Wood Chips with a Natural Resin Based on Tannins Reinforced with Sugar Cane Molasses Intended for Building Insulation: Physico-Mechanical and Thermal Properties

The objective of this work is to develop new biosourced insulating composites from rice husks and wood chips that can be used in the building sector. It appears from the properties of the precursors that rice chips and husks are materials which can have good thermal conductivity and therefore the combination of these precursors could make it possible to obtain panels with good insulating properties. With regard to environmental and climatic constraints, the composite panels formulated at various rates were tested and the physico-mechanical and thermal properties showed that it was essential to add a crosslinker in order to increase certain solicitation. an incorporation rate of 12% to 30% made it possible to obtain panels with low thermal conductivity, a low surface water absorption capacity and which gives the composite good thermal insulation and will find many applications in the construction and real estate sector. Finally, new solutions to improve the fire reaction of the insulation panels are tested which allows to identify suitable solutions for the developed composites. In view of the flame tests, the panels obtained are good and can effectively combat fire safety in public buildings.

Analysis of microRNA Expression Characteristics Related to Low Temperature Stress in Chewing Cane

[Objectives]To explore microRNA expression characteristics related to low temperature stress in chewing cane.[Methods]The research on miRNA under abiotic stress of sugarcane at home and abroad mainly focused on the types and regulation of miRNA under cold,heat,drought,high salt,and mechanical stress.However,there are few studies on miRNA under low temperature stress in chewing cane.The target genes of miR394 and miR825 in chewing cane were predicted and functionally analyzed by bioinformatics technology.[Results]The results showed that the target genes of miR394 and miR825 were mainly members of the WRKY transcription factor family,involved in plant growth,development and stress resistance.Real-time fluorescence quantitative PCR analyzed the expression characteristics of target miRNA in different tissues of chewing cane at different periods of low temperature stress.[Conclusions]The results showed that the expression of chewing cane miR394 and miR408 had temporal and spatial specificity and tissue specificity,both of which could respond to low temperature stress with significant differential expression.

Candy cane syndrome:A systematic review

BACKGROUND Candy cane syndrome(CCS)is a condition that occurs following gastrectomy or gastric bypass.CCS remains underrecognized,yet its prevalence is likely to rise due to the obesity epidemic and increased use of bariatric surgery.No previous literature review on this subject has been published.AIM To collate the current knowledge on CCS.METHODS A literature search was conducted with PubMed and Google Scholar for studies from May 2007,until March 2023.The bibliographies of the retrieved articles were manually searched for additional relevant articles.RESULTS Twenty-one articles were identified(135 patients).Abdominal pain,nausea/vomiting,and reflux were the most reported symptoms.Upper gastrointestinal(GI)series and endoscopy were performed for diagnosis.Surgical resection of the blind limb was performed in 13 studies with resolution of symptoms in 73%-100%.In surgical series,9 complications were reported with no mortality.One study reported the surgical construction of a jejunal pouch with clinical success.Six studies described endoscopic approaches with 100%clinical success and no complications.In one case report,endoscopic dilation did not improve the patient’s symptoms.CONCLUSION CCS remains underrecognized due to lack of knowledge about this condition.The growth of the obesity epidemic worldwide and the increase in bariatric surgery are likely to increase its prevalence.CCS can be prevented if an elongated blind loop is avoided or if a jejunal pouch is constructed after total gastrectomy.Diagnosis should be based on symptoms,endoscopy,and upper GI series.Blind loop resection is curative but complex and associated with significant complications.Endoscopic management using different approaches to divert flow is effective and should be further explored.

Correlation and Path Coefficient Analyses in Sugarcane Genotypes of Ethiopia

To study the relations of certain morphological and sugar quality characters with sugarcane yield, an experiment was conducted at Wonji and Metehara Sugar Estates, Ethiopia between March 2012 and October 2013. The experiment, comprising of 400 sugarcane genotypes of which 174 were local that were collected from different regional states of Ethiopia and 226 introduced, was laid out in partial balanced lattice design with two replications. Data was collected on cane yield and its components, sugar yield and sugar quality traits. ANOVA, correlation and path coefficient analysis were done. Analysis of variance revealed significant differences (P < 0.01) for all the characters studied. Cane yield showed strong positive and highly significant (P < 0.01) correlation with millable cane number (r = 0.832), single cane weight (r = 0.528), stalk height (r = 0.517) and sugar yield (r = 0.987). There was also positive significant (P = 0.05) correlation of tiller count and cane diameter with cane yield. Path analysis revealed the highest positive direct effect of millable cane number (0.812) on cane yield followed by single cane weight (0.682) and pol percent (0.550). However, stalk diameter and brix percent had considerable negative direct effects and indirect positive effects through single cane weight on cane yield. Therefore, in view of their significant positive association with cane yield, indirect effects of stalk diameter and brix percent via single cane weight should be considered during selection. Genotypes should be selected on the basis of millable cane number, single cane weight and pol percent for getting higher cane and sugar yield.

Residue of Organphosphorus Pesticides in Chewing Cane Juices Detected by QuEChERS and GC-NPD Method

[ Objective] The paper was to establish a quick detection method for residue of organphosphoras pesticides in chewing cane juices and provide guarantee for edible safety of chewing juice. [ Method] By using QuEChERS and GC-NPD method, a rapid analysis method for residue of six kinds of organphosphorus pesti- cides （dichlorves, chlorpyrifos-methyl, malathion, fenthion, chlorpyrifos and triazophes） in sugarcane juices was established. [ Resdt] QuEChERS method was significantly superior to traditional extraction method and could extract six kinds of organphesphorus pesticides from chewing cane juices effectively, which gready saved organic reagent and time. Good linearity was found in different standard curves; when the concentration of pesticides was from 0. 020 toO. 100 rag/L, the re- covery rate was from 68.58% to 92.85%, and relative standard deviation （RSD） was ranged from 2.16% to 9.89%. [ Conclusion] The sensitivity, accuracy and precision of QuEChERS method were consistent with the technical requirements of pesticide residue determination. It not only could shorten sample processing cycle effectively, but also ensure that no impurity was in the sample peak and the recovery rate was also consistent with the requirements of residual analysis.

Isolation of lactic acid bacteria from sugar cane juice and production of lactic acid from selected improved strains

Lactic acid bacteria (LAB) were isolated from fresh sugar cane juice. It was found that several isolates exhibited a clear zone and growth on deMan, Rogosa, Sharpe (MRS) agar supplemented with sodium azide, bromocresol purple and sucrose. However, only 17 isolates which formed large yellow areas were selected for further investigations. These isolates were further identified according to their morphological and biochemical characteristics. It was found that 10 of these isolates were homofermenters. One of these 10 isolates was selected for mutagenesis using chemical (Ethidium bromide) and physical (UV-B) mutagens followed by biochemical characterisation. A total of 112 mutants were isolated and 9 homofermentative isolates were further investigated for their ability to produce lactic acid. 1H-NMR spectroscopy confirmed that all mutant isolates produced lactic acid as the sole fermentation product.

Agronomic and Economic Evaluation for Intercropping between Chewing Cane and Peanut

[Objectives]To explore the proper intercropping pattern between chewing cane and peanut.[Methods]A field experiment was carried out to investigate the yield and economic benefit of chewing cane and peanut,as well as the changes in soil properties under different chewing cane/peanut intercropping patterns.Three chewing cane/peanut intercropping patterns were designed,in which with every row of chewing cane intercropping one row of peanut(CP_(1)),intercropping two rows of peanut(CP_(2))and chewing cane mono-cropping(MC).[Results]It had no significant effect on the agronomic characters of chewing cane and peanut in CP_(1)and CP_(2),compared with MC.The soil properties before the planting(BP)and after the harvest(AH)indicated that the chewing cane/peanut intercropping patterns significantly increased soil organic matter and soil available nitrogen contents,but decreased soil available potassium contents,and CP_(2)had better effect on soil structure than CP_(1).The total production value and economic benefit were increased significantly on the CP_(1)and CP_(2),comparing the MC,and the benefit of CP_(2)was higher significantly than that of CP_(1).The land equivalent ratios(LER)for CP_(1)and CP_(2)were 1.94 and 1.72,respectively,which was significantly higher than that of MC(0.83).Although planting cost was increased in chewing cane/peanut intercropping patterns partly,the production value and the profits were enhanced significantly.[Conclusions]CP_(2)could be significantly advantageous for the yield and benefits of chewing cane and peanut and soil properties.The favorable intercropping pattern for economic return would be one row of 120 cm width for chewing cane with two rows of peanut.

Properties of Rattan Cane Reinforced Concrete Facade Subjected to Axial Loading

The use of steel reinforced concrete facade is gradually becoming unpopular because of the damage caused to the elements as a result of corrosion of the steel reinforcement. It is now possible to build lightweight and slender concrete structures which are invulnerable to corrosion with the use of fiber reinforcements, which are gradually replacing the corrosion prone steel. This paper describes the construction of faqade panels made of rattan cane reinforcements and steel reinforcements, ten number model sized elements of area 0.15 m2 and a depth of 40 mm were considered, with five panels for each reinforcement type. The elements were subjected to incremental load of 1 kN until failure occurred. Deflections were measured for each element, and crack width was measured at failure load. The results for both types of reinforcements when compared showed the rattan cane reinforced panels failing earlier than the steel reinforced panels. However a lower defection and crack width was recorded in the rattan cane reinforced panel. This paper concludes that the lower crack width formed after failure in the rattan cane reinforced panel gave it advantage over the steel reinforced panel, since it has lower space for the ingress of water which is the main agents of corrosion.

Yields of Polyhydroxyalkanoates （PHAs） during Batch Fermentation of Sugar Cane Juice by Alcaligenes latus and Alcaligenes eutrophus

In this work, sugar cane juice was fermented to produce polyhydroxyalkanoates （PHAs） by Alcaligenes latus TISTR 1403 and A. eutrophus TISTR 1095. The juice was characterized and composed of total sugars 105.5 g·L^-1 （sucrose 36.6g·L^-1 , fructose 26.0g·L^-1 , glucose 21.8g·L^-1 and other sugars 21.1g·L^-1 ）. Each inoculums （ 10%, v/v） was separately cultivated in the medium containing 20g·L^-1 total sugars under condition （30℃, 200 rpm, pH 6.5-7）. It was found that the A. eutrophus can be grown better than the A. latus. Only the A. eutrophus was further cultured under different total sugar concentrations （20, 30, 40 and 50g·L^-1 ）. The optimal contents of total sugar, dry cell mass （DCM） and maximum PHAs were obtained at 50g·L^-1 , 6.013g·L^-1 and 1.84g·L^-1 , respectively after 60 h fermentation which were converted to biomass yield （Yx/s）, product yield （Yp/5）, specific product yield （Yp/x） and productivity of 0.163, 0.05, 0.306 and 0.031 g.Llhl. Large scale of PHAs production was conducted in 5 L fermentor using the optimal condition obtained under 30% dissolved oxygen. The DCM and the maximum PHAs were 5.881g·L^-1 and 1.281g·L^-1 which were calculated to values of Yx/s, Yp/s, Yp/x and productivity at 0.19, 0.04, 0.218 and 0.021g·L^-1 , respectively.

The Effect of Silane Treated Sugar Cane Bagasse on Mechanical, Thermal and Crystallization Studies of Recycled Polypropylene

This article describes the results of an investigation on the influence of loading silane treated sugar cane bagasse (SB) on the morphology and properties of recycled polypropylene (rPP). The samples are prepared through melt extrusion followed by injection moulding. The Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) results show that SB-rPP composites have a fairly strong interfacial interaction and a change in crystallization for the highest containing SB composite, however, some fibre pull-outs are observed as the SB content is increased. The interaction influences the thermal and mechanical properties of the samples in a complex way. There are strong indications of a stronger interfacial interaction on the highest containing SB composite, which is supposedly accountable for the increased crystallinity and melting temperature.

The Cain Allusion in Jean Toomer's Cane

Published in 1923, Cane, the representative work of Jean Toomer has been widely studied by critics. Among which,one of perspectives is to analyze the biblical metaphors in the novel. A closer reading of the book shows that the Cain allusion is an unifying theme, for the author once refers Cane as Cain, and most of the characters in the novel are blacks who are believed to be descendant of Cain because of the color of their skin as well as the same suffering of isolation and alienation. Here a study of the Cain allusion in the novel is presented with focus on Karintha's story in the first part of Cane.

Economic profitability of cane based furniture enterprises of Chittagong City Corporation Area, Bangladesh

An exploratory survey was conducted to assess economic profitability of cane based furniture enterprises in Chittagong City Corporation area of Bangladesh. A multistage random sampling was adopted to carry out the study. Based on the total investment the enterprises were divided into large, medium and small.. Most of the entrepreneurs （55%） are in the age class 40-50 years and only （18.33%）are ＞50 years. In small and medium category lowest entrepreneurs （8.33% each） are found graduate and 18.33% in large farm. Most of the enterprises are in the small category （45%） and 66.67% labors are skilled whereas only 33.33% are unskilled. Seven articles of sixteen different sizes were identified made from cane, which are Sofa （45 cm × 45 cm, 50 cm × 50 cm and 55 cm × 55 cm）, Dinning （4ch. 1tab,and 6ch. 1tab.）, Bed （1 m × 2m, 1.3 m × 2.3 m and 1.5 m × 2.3 m）, Chair （45 cm × 45 cm and 50 cm ×50 cm）, Rocking chair （large size,medium and small size）, Dolna （Hanging and Running） and Partition. In all the three category enterprises chair （45 cm × 45 cm） was produced in highest number and the lowest production was Bed （1.5 m × 2.3 m）. The total net benefit （2089 US$） and benefit cost ratio （1：16）was the highest for large cane enterprises. So among three categories of the cane enterprises the large enterprises are more profitable than others.

The Fertilizer-Effect on Al, Ba, Fe, Mn and Ni Released in a Watershed with Influence of Sugar Cane Crops in the S&#227;o Paulo State, Brazil

S?o Paulo State is the main sugar cane producer and these agricultural activities are carried out in predominantly sandy soils, which require large amounts of phosphate fertilizers and amendments. This work evaluated the fertilizer-effect on the Al, Ba, Fe, Mn and Ni released in a watershed with influence of sugar cane crops in the S?o Paulo State, Brazil, namely the Monjolo Grande Stream basin. Five surface water sampling campaigns were carried out at the mouth of Monjolo Grande Stream in February, April, June, September and November 2010, characterizing the following parameters: discharge, pH, temperature, electric conductivity, dissolved oxygen and total and dissolved concentrations of Al, Ba, Fe, Mn and Ni. Approximately 99% of Al and Fe are transported annually in association with suspended sediments carried to the Monjolo Grande Stream by sheet erosion. The results also demonstrated that the increasing Al, Ba, Fe and Mn concentrations dissolved in the waters of the Monjolo Grande Stream basin in the wet season are associated to phosphate fertilizers and amendments that are used extensively in agrichemical activities. However, with the current application rates, there has been no increase in the dissolved concentrations of these metals at levels that could pose risks to human health.

Is Cane Sugar Production for Biofuel a Good Practice in Semi-Arid Systems? A Special Reference to the Olifants River Catchment, Mpumalanga, South Africa

The aim of this paper is to analyse the possible impacts of proposed biofuel production at Hoedspruit in the Olifants River Catchment. These impacts are looked at in terms of availability of water and subsequent consequences on downstream users, especially the Kruger National Park that is mandated to conserve and protect biodiversity in all facets and fluxes in its area of jurisdiction. Based upon a review of experiences with biofuel production and impacts around the world, water availability for sugar cane production to support proposed biofuel production was found to be a problem in the region that has an average rainfall of only 450 mmper annum. The Olifants River system already has a deficit of about 200 million m3/a;hence the sustainability of the sugar cane based biofuel industry in the proposed area is questioned in this review. It is advised that alternative plants for the production of biofuel that may not consume large quantities of water be examined.
