Abstract:
is present project investigated the impact penetration response of woven jute fiber reinforced composites subjected to wide range of low impact velocities. Hand layout woven jute fibers are thermally compressed to ensure no internal defects formed in the composites. Six layers of woven jutes are stacked together using different fiber orientations [0/q/0]s. Low impact velocities are used ranging between 5 – 20 m/s. Force-time, force-displacement and energy-time curves are obtained automatically during the impact tests. The results are then discussed with considering the composite fragmentations and failure mechanisms. It is found that 00composite orientations capable to absorb sufficiently impact energy for 5 m/s but not for velocity greater than 10 m/s. When fiber orientations used between 15 – 450, the composite impact resistance increased indicating two significant peak forces. These peak forces represent different type of failure mechanisms occurred during the striker progresses.

Abstract:
In a well-known passage in his Germania Tacitus lists among the occupants of a district apparently corresponding to the modern Denmark the Aviones, the Anglii, the Varini and the Eudoses; some of these can be readily identified with tribes mentioned in the Old English Widsith. If, as seems possible, the Eudoses are the Jutes, the Ytum of Widsith 26b, there is certainly no exact phonological equivalence between the names; but the Varini correspond precisely to the Wernum, Wœrnum (dative plurals) of Widsith 25b and 59a, and the Anglii correspond to the Engle, Englum (nominative and dative plural respectively) of Widsith 44a and 61a.

Abstract:
About 170 round barrows and 15 flat graves from Kent are here recorded, almost all on the Chalk. In addition there are at least as many ring-ditches, mostly of ploughed-out round barrows, in Thanet, only a small selection of which are here included as a full list is being prepared by the Trust for Thanet Archaeology. Nine sites have yielded primary central inhumations and ten have contained primary central cremations. Four sites have yielded burials in their encircling ditch. Warrior equipment has come from two sites, and ‘Wessex’ interments from another two. Barrow Wouldham 1/THAN contained a central primary cremation in a four-post mortuary structure with parallels in the Toterfout-Halve-Mijl cemetery in the Netherlands, with which area relations are suggested. One site (Lydden 1/DOV) is identified as the Ellenbeorge of an Anglo-Saxon land charter. Several Bronze Age round barrows were used by the Jutes and Saxons for their intrusive burials, and there are two instances of an Anglo-Saxon cemetery being sited to adjoin a Bronze Age round barrow. More than twenty sites have recorded local names of which the most frequent general name is Mount. Some of the best surviving barrows are beside or near the North Downs Way and the Pilgrims' Way.

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

Abstract:
Jute (Corchorus spp.) belongs to the Malvaceae family, and there are two species of jute, C. capsularis and C. olitorious. It is the second-largest natural bast fiber in the world according to production, which has diverse uses not only as a fiber but also as multiple industrial materials. Because of climate change, plants experience various stressors such as salt, drought, heat, cold, metal/metalloid toxicity, and flooding. Although jute is particularly adapted to grow in hot and humid climates, it is grown under a wide variety of climatic conditions and is relatively tolerant to some environmental adversities. However, abiotic stress often restricts its growth, yield, and quality significantly. Abiotic stress negatively affects the metabolic activities, growth, physiology, and fiber yield of jute. One of the major consequences of abiotic stress on the jute plant is the generation of reactive oxygen species, which lead to oxidative stress that damages its cellular organelles and biomolecules. However, jute’s responses to abiotic stress mainly depend on the plant’s age and type and duration of stress. Therefore, understanding the abiotic stress responses and the tolerance mechanism would help plant biologists and agronomists in developing climate-smart jute varieties and suitable cultivation packages for adverse environmental conditions. In this review, we summarized the best possible recent literature on the plant abiotic stress factors and their influence on jute plants. We described the possible approaches for stress tolerance mechanisms based on the available literature.

Abstract:
The country of India is the unique where different cultural heritage as well as festivals were found. Mainly the West Bengal state is known as various religious festivals, but Durga Puja is one of the biggest and end of this festival idol are immersed in the water bodies. Sainthia town found in the district of Birbhun, West Bengal, India which is present in the south bank of the Mayurakshi river. The idol immersion mainly effect on water as well as sediment quality of this river Mayurakshi near railway bridge at Sainthia. The study will be discussed for immersion effect of this sampling station, because in this point totally Sainthia town Durga idols were immersed. The water and sediment samples were collected at 7:30 am on 9th October 2019 during pre-immersion (before immersion) and 7:30am on 10th October 2019 during the post immersion (after immersion) in this time of periods. Mainly, the Durga idols are been made up by non-biodegrable substances such as clay, plaster of paris, cloths, paper woods, thermocols, jutes and synthetic paints etc. these are mainly toxic substances. Over all the used materials in making of idol, the thermocol is nonbiodegradable while paints contained highly toxic heavy metals like Cr, Cd and Pb. In this study has been made to analysis the physicochemical parameters like temperature, pH, TS, TDS, TSS, EC and three heavy metals like Cr, Cd and Pb on the collected water and sediment samples of the Mayurakshi river on before and after idol immersion periods of near railway bridge sampling station. The analysed results by based on various physicochemical parameters showed that the after immersion in the river Mayurakshi increases concentration of heavy metals and changes other physicochemical parameters of the both water and sediment samples. Finally concluded that, these changes of different parameters are harmful for aquatic life and human beings as well as the level of water pollution highly increases in this Mayurakshi river. So, the huge religious activities mainly causes of the water pollution where huge disturbing aquatic ecosystem.

Abstract:
Cette thèse revient sur deux expériences historiques durant lesquelles le double système de juridictions civiles et pénales alors instauré en France se voit remis en cause : d'un côté, les juges de paix dont l'action aux côtés des magistrats des tribunaux est contestée à la fin du XIXe siècle ; de l'autre, les juges de proximité créés en 2002 et aussitôt décriés. Dans les deux cas, ces juges, chargés des petits litiges, sont soumis à un statut particulier qui les distingue de la magistrature professionnelle et les installe dans une position de « juges profanes ». Ce travail de doctorat restitue alors en détail deux tentatives historiquement distinctes de « normalisation » statutaire en observant pourquoi une telle opération sociale s'avère à chaque fois délicate et aboutit à la suppression pure et simple de ces figures de justice. Il compare ce faisant les modifications des structures sociales, économiques et politiques rendant ces situations de pluralisme judiciaire intenables. Avec l'instauration d'un régime républicain fondé sur l'égalité des droits et la prégnance de l'Etat en matière judiciaire, l'idée d'un double système d'exercice de la fonction de justice pose question tant au niveau de la légitimité politique, du recrutement d'un personnel dédié que des pratiques autorisées. De ce fait, l'idée de juges « proches », bien que mobilisée dans l'espace politique, devient de moins en moins une réalité institutionnelle concevable. Mêlant dépouillement de dossiers individuels archivés, consultation de revues professionnelles, travail statistique et analyse d'un corpus d'entretiens, ce travail contribue ainsi à une sociologie de l'appareil judiciaire français.

Abstract:
Le magistrat va pouvoir recourir tout d'abord a une recherche interne de la verite a l'audience publique ou en chambre du conseil vers les composantes irreductibles de tout litige, en l'occurrence les pieces du proces et les parties a l'instance. Cette recherche interne va permettre au juge de beneficier d'une connaissance des pieces par leur production volontaire ou forcee et de realiser egalement un examen de celles-ci si leur sincerite est contestee ou leur interpretation necessaire. Cette meme recherche interne peut conduire aussi le magistrat vers un controle ou des investigations concernant les declarations es parties susceptibles de constituer un aveu, un serment une presomption ou l'equivalent d'un commencement de preuve par ecrit. Par ailleurs le juge va pouvoir le cas echeant instaurer une recherche externe de la verite en direction des faits, hors de l'audience ou, vers des tiers etran gers au lien, d'instance initial. Cette recherche externe va permettre au magistrat de mener relativement aux faits du proces des investigations personnelles ou de confier a un homme de l'art une mission technique. Cette meme recherche externe peut conduire egalement le juge a proceder a l'audition de tiers en qualite de temoin, d'amicus curiae ou encore a la mise en cause de certains autres ; enfin le tiers associe a cette manifestation de la verite peut avoir lui-meme la qualite de magistrat du parquet ou du siege
The inner search for truth will allow the judge to benefit from a knowledge of the documents by a volontary or forced exhibition and also to carry out an examination of these, if their sincerity is challenged or their interpretatiion is necessary. This same inner search can also lead the magistrate to a supervisioin or to investigations concerning the parties declarations susceptible of constituing a confession, an oath, a presumption of the beginning of a written proof equivalent. By another way, the judge will establish an outer search for truth in direction of the facts out of the course or toward third persons forrigners from the initial case. This outer search will allow the magistrate to lead personnal investigations cooncerning the case's facts or the intrust a specialist for a technical mission. This same outer search can also lead the judge to proceed to the audition of thirds as witnesses, as amicus curiae, or to the bringing into of some others finally, the third associated to this truth manifestation can himself be a publiv peosecutor or a judge

Abstract:
Weld lines are formed inevitably when two separate melt fronts rejoin during injection molding. It has been reported that weld lines greatly weaken the strength of injection-molded parts. Therefore, in this paper the weld property of injection molded jute /PLA and jute/PP dumbbell shape specimen with weld line was investigated by changing pellets materials. In the study pultrusion technique was adopted to fabricate jute/PLA and jute/PP long fiber pellets (LFT) and it was found that fiber bundles in LFT specimens were not separated and dispersed well. As a result, in this paper re-compound pellets of LFT, i.e. RP was made. Then LFT, RP, and hybrid mixtures with the hybrid ratios of LFT50:RP50 were used to mold dumbbell shape specimens with or without weld line. In particular, the influence of different pellets on weld line strength of injection molded jute/PLA and jute/PP dumbbell shape specimens with weld line was discussed based on tensile test and SEM observation. It was found that tensile strength of RP specimens was higher than that of LFT both for jute/PLA and jute/PP, because fiber distribution and interfacial property of RP was much better than that of LFT. Weld line strength of RP was improved than that of LFT both for jute/PLA and jute/PP. RP of jute/PLA was more effective to improve the weld property than that of jute/PP. Weld line strength of jute/PP LFT increased as holding pressure increased from 44 to 88 MPa and decreased at 132 MPa holding pressure. It depends on the co-effect of fiber orientation and voids content.

Abstract:
This study dealt with the effect of hybridization of jute fiber and glass fiber on the mechanical properties of fiber reinforced thermoplastics injection moldings. In the glass/jute hybrid materials the weight fraction of glass fiber was fixed at 10wt% and that of jute fiber was varied from 5wt% to 30wt%. Dumbbell-shaped specimens were prepared by injection molding, and the static tensile tests were performed with acoustic emission (AE) monitoring. AE monitoring was conducted to understand the fracture behaviors of glass/jute hybrid materials. By adding the glass fiber to jute fiber reinforced plastics the tensile strength was improved. However, too much content of jute fiber could not achieve the improvement of strength because the uniform distribution of glass fiber was restricted by too much bulky jute fiber. After tensile test the fiber distribution on the fracture surface was observed. Based on the fiber distribution of jute fiber and glass fiber the strength prediction was attempted by introducing the rule of mixture.

In ASME 2012 International Mechanical Engineering Congress and Exposition. American Society of Mechanical Engineers, 2012. http://dx.doi.org/10.1115/imece2012-87775.

Full text
Abstract:
In this research, the flexible interphase concept was introduced to enhance the poor mechanical properties of jute fiber reinforced unsaturated polyester matrix composites. The jute cloth reinforcement was obtained from recycled coffee bags. These jute cloths after washing by water and drying were soaked in mixture of Polybutadiene Epoxydied as flexible resin and acetone for 10 seconds. Several mixtures consist of 0, 2, 3.5, 5 and 8 wt% of Polybutadiene Epoxydied and 100, 98, 96.5, 95 and 92 wt% of acetone, respectively, to form flexible interface around the jute fibers. Jute cloth reinforced unsaturated polyester matrix composites with different flexible interphase incremental weight ((Wa-Wb)/Wb) ratios were fabricated by hand lay-up method and examined by a series of mechanical tests. The mechanical testing including tensile, bending, Izod strength impact and drop impact was carried out for these composites to evaluate the effect of the flexible interphase and acetone on the jute cloth composites. The flexible interphase succeed to control the mechanical properties of jute fiber reinforced unsaturated polyester matrix composites. Inserting flexible interphase between unsaturated polyester matrix and jute fibers leads to smooth fluctuation, less matrix cracking, in the second part after the knee point of each stress-strain curve as exhibited in composites with higher flexible interphase incremental weight ratio. This means not only the brittle matrix but also interface/interphase dominates the multiple matrix cracking behavior in jute cloth reinforced unsaturated polyester matrix composites. Inserting flexible interphase between unsaturated polyester matrix and jute fibers leads to less number of multiple cracking as shown in the second portion of flexural stress-displacement curve. This means the number of multiple cracking are dominated by flexible interphase. The impact strength of jute cloth reinforced unsaturated polyester matrix composites with flexible interphase incremental weight ratio of 1.2% is higher than that of jute cloth reinforced unsaturated polyester matrix composites without flexible interphase by about 45%. The impact energy after maximum load has increased significantly with all flexible interphase incremental weight ratios.

Abstract:
As well known, the corrosion resistance and durability of the material are always considered in the safety design of the materials. In this study, the jute fabric from recycled coffee bags was used to fabricate ecologically friendly composites. Jute fabrics with two kinds of different moisture contents were used to fabricate the natural fiber reinforced composites, and the hot water immersion properties have been evaluated. Additionally, the effects of the hybridization with glass woven fabric laminated structures were also investigated. Jute/Jute laminated composite, Jute/Jute/Glass, and Glass/Jute/Glass laminated hybrid composites had been fabricated by hand lay up method. A preliminary investigation on the effect of moisture contents of the jute fabric on the mechanical properties of the jute and jute/glass hybrid composites was discussed based on the results of 3 point bending test. Moreover, the durability of the composites in the hot water immersion was also evaluated. The effects of hot water immersion on the mechanical properties were investigated by the way of 3 point bending test. The specimens were immersed in hot water maintained at 80°C with the immersion time of 24, 120 and 240 hours. Specimens were taken out from the hot water at the same time and repeated the 3 point bending test after each immersion time and the weight changes had been measured. Results showed that the Jute/Jute composite absorbed water easily, and it could be noted that all of the natural dried composites showed comparable higher water absorbed value to the deeply dried ones. The bending strength after aging decreased remarkably. In particularly, all of the natural dried composites showed higher bending strength than the deeply dried one before aging. However, after 120 hours aging, on the contrary, almost the deeply dried composites showed comparable higher value to the natural dried ones. That could be due to the better bonding between fiber and matrix for the deeply dried composites which decreased the water absorption of the composites. Additionally, the hybrid structure is effective in protecting the composites from water absorbing especially for the Glass/Jute/Glass hybrid one.

Abstract:
As well known, the durability of the material is always considered in the safety design of the materials. Therefore in this study, the property of injection molded hybrid jute/glass reinforced polypropylene (PP) composites was firstly investigated after the hot water immersion experiment. The hydrothermal aging performance was investigated in the 80 °C hot water immersion experiment with a series of immersion time and different fraction of jute fiber and the effects of hot water immersion on the mechanical properties of composites have been evaluated based on the tensile test. Water absorption and weight loss of the reinforced PP composites were recorded and discussed. It is found that with the increase of jute fiber content, the tensile modulus is increased. However, the increasing of jute fiber content decreased the tensile strength of hybrid composites. For the effect of hydrothermal aging, the weight by water absorption was significantly affected by the jute fiber content. The specimens with higher jute fiber content absorbed water easier and significant materials loss by aging was also occurred. Tensile properties of hybrid composites which contain jute fiber showed the lower tensile strength than the monotonic glass/PP composite. It is considered that the hydrophilic property of jute fiber decreases the resistance of the hybrid composite in high humidity environment.

Abstract:
Natural composites have been important materials system due to preservation of earth environments. Natural fibers such as jute, hemp, bagasse and so on are very good candidate of natural composites as reinforcements. On the other hand regarding matrix parts thermosetting polymer and thermoplastic polymer deriver form petrochemical products are not environmental friendly material, even if thermoplastic polymer can be recycled. In order to create fully environmental friendly material (FEFM) biodegradable polymer which can be deriver from natural resources is needed. Therefore poly(lactic acid) (PLA) polymer is very good material for the FEFM. However, PLA is very brittle polymer, so that polymer chemists have been made the efforts to make tough PLA. In this paper Jute/PLA composites was fabricated by injection moldings and mechanical properties were measured. It is believable that industries will have much attention to FEFM, so that injection molding was adopted to fabricate the composites. Long fiber pellet pultrusion technique was adopted to prepare jute fiber-PLA pellet (Jute/PLA). Because it is a new method which is able to fabricate composite pellets with relative long length fibers for injection molding process, where, jute yarns were continuously pulled and coated with PLA resin. Here two kinds of PLA materials were used including the one with mold releasing agent and the other is without it. After pass through a heated die whereby PLA resin impregnates into the jute yarns and sufficient cooling, the impregnated jute yarns were cut into pellets. Then Jute/PLA pellets were fed into injection machine to make dumbbell shape specimens. In current study, the effects of temperature of heat die i.e. impregnation temperature and the kind of PLA were focused to get optimum molding condition. The volume fractions of jute fiber in pellet were measured by several measuring method including image analyzing, density measurement and dissolution methods. And the mechanical property were investigated by tensile and Izod testing. It is found that 250 degree is much suitable for Jute/PLA long fiber pultrusion process. Additionally the jute fibers seem much effective to increase the tensile modulus and the Izod strength. That is to say, the addition of Jute fiber in PLA, the brittle property can be improved.

Abstract:
The rising concern towards environmental issues and lower production costs has led to increasing interests on the use of natural fibers to replace glass fibers as reinforcements. In this paper, the mechanical and physical properties of natural fiber composites and their hybrids or sandwiches were investigated. Jute woven fabric composites and their sandwiches were produced by applying vacuum assisted resin transfer molding (VARTM). For the composite sandwiches, glass woven composites were placed at the outer surfaces of jute woven composites and could act as strong skins. Therefore, the bending properties of jute-glass woven composites are higher than those of jute woven composites. The thin glass woven composites at the outer layer of composite sandwich also reduce the rate of water absorbed by the composites. The water absorption in jute-glass woven composites is lower than those in jute woven composites. Nano fillers that were added into the composites were expected to improve the mechanical and thermal properties of the composites. So far, matrices with 1 wt% of nano fillers have been successfully infused into fibers through VARTM process. The thermal properties of glass woven composites with nano fillers are significantly increased. However, the addition of nano fillers in jute fiber composites does not increase their thermal properties as the decomposition of the natural fiber occurs at the temperature whereby the epoxy matrix starts to degrade.

Abstract:
The extensive research efforts are currently on progress all over the world to develop and characterize the green composites with high performance at an affordable cost due to the growing environmental awareness. Biodegradable nanophased jute composites were manufactured using chemically treated jute fabrics, Biopol, and nanoclay using compression molding techniques for this study. Nanoclay infusion into the thermoplastic is a challenging issue and was infused using solution intercalation technique. The surface modification of jute fibers was accomplished by performing subsequent chemical treatments such as detergent washing, dewaxing, alkali and acetic acid treatment. The morphology of the modified surface was studied using SEM and FTIR. Thermal performance of the treated fibers was studied using the TGA. The thermal, dynamic mechanical and mechanical properties of biodegradable nanophased jute composites were evaluated by TGA, DMA and flexure test respectively. Enhanced thermal and mechanical properties were observed in modified and nanophased jute biopol composites.

Abstract:
Green composites are biocomposites where both matrix and reinforcement derive from renewable or recycle resources and have attracted much attention in recent years. In particular, jute/polypropylene (PP) is one of the good choices of green composites. Further, investigation of long-term behavior of composite is an importance in designing in composite structures. However, so far, very few research works focus on the fatigue property of injection molded jute/PP fabricated by long fiber pellets (LFT). In this study, the pultrusion technique was adopted to prepare LFT pellets for injection molding and LFT dumbbell specimens with different jute fiber weight percent of 10, 20, 30, 40, and 50 percent were molded. Low cycle fatigue property of injection molded jute/PP composites was investigated by tensile test. Different cycle times of 30, 60 and 100 were adopted to evaluate the effect of cycle times and fiber content on the fatigue property of injection molded jute/PP composites.
