    Fique is a biodegradable natural fiber derived from the Colombian Agavaceae family, originating in tropical America and traditionally used for the manufacture of packaging and cordages. Today, however, new uses are being developed. To meet the need for new good-quality, sustainable, low-cost construction materials for social housing, construction materials have been produced that combine different kinds of natural fibers, including fique, to improve their strength and physical properties.

    Full Text Available The paper discusses the decoration of pottery of the Neolithic Jomon culture (Japanese Archipelago, 13600–900 BC. The comb-impressed pattern produced by various kinds of cord or rope stamps is considered as the ‘calling card’ of Jomon pottery from the earliest cultural periods to the latest. Another kind of decoration recognized recently uses the cord not as a patterning tool, but as an essential motif of decorative composition. High relief elements imitate cordage forms and structures – knots, loops, hanging cord, net, etc. This kind of decoration corresponds to the pottery of Mid-dle Jomon period (3500–2500 BC sites located in northern and north-eastern Honshu and southern Hokkaido. It is supposed that the introduction of images of real material object into the field of decorative art was reasoned by the meaning of cord and cordage as cultural signs during the Middle Jomon period. Interesting parallels to some cordage structures reconstructed on Middle Jomon pottery decoration are well known in traditional Japanese culture of VI–XX cc. Analytical interpretation of this resemblance may became the subject of special research.

    Full Text Available Mucocele resprented as a lesion that usually happened as an effet of accumulation and extravasation of secret minor salivary gland dof cheek and lip, which gave clinical feature like a bubble of mucosa. This lesion commonly caused by the effect of continuous trauma. Treatment of mucocele was surgery, e.g. excision marsupialization, cryosurgery and ablation by laser. The treatment for mucocele in children was more complex because problem of behavior during treatment so it can be conducted with a few modification without causing trauma. With micro marsupialization or cordage at the handle of mucocele, hence difficulty of excision mucocele in a child can be overcome, although the child is not cooperative.

    A technique of mounting of a localization system at the WWER-440 NPP is described. The localization system consists of air-lift devices located in pressurized building (shaft) 12.6 thousand m 3 volume. Air-lift devices are placed in 12 bayers with 3.37 m spacing over the height of localization shaft. Every layer of air-lift devices consists of 18 supporting H-beams number 60 of 8.5 m in length. The total host of air-lift devices and metal works of servicing platforms is equal to 725 t. The air-lift device consists of the large number of details (660 pieces of 500-2500 kg mass and above 2500 pieces of 500 kg mass), which causes the necessity of accomplishing a large volume of assembling and welding works. To reduce the labour content in the mounting zone and volume of work accomplished at the height the method of large-structure mounting of air-lift devices was suggested. The method lies in ground assembly of air-lift structures on the basis of several supporting beams and their following lifting to the corresponding layer. The large-structure mounting of localization shaft enables to reduce by 25-30% the length of joint welds made during the mounting as well as the volume of transport and cordage works; to reduce the time of building crane usage and 1.5-1.7 times the total periods of works

  12. Sisal organosolv pulp as reinforcement for cement based composites

    Full Text Available The present work describes non-conventional sisal (Agave sisalana chemical (organosolv pulp from residues of cordage as reinforcement to cement based materials. Sisal organosolv pulp was produced in a 1:1 ethanol/water mixture and post chemically and physically characterized in order to compare its properties with sisal kraft pulp. Cement based composites reinforced with organosolv or kraft pulps and combined with polypropylene (PP fibres were produced by the slurry de-watering and pressing method as a crude simulation of the Hatschek process. Composites were evaluated at 28 days of age, after exposition to accelerated carbonation and after 100 soak/dry cycles. Composites containing organosolv pulp presented lower mechanical strength, water absorption and apparent porosity than composites reinforced with kraft pulp. The best mechanical performance after ageing was also achieved by samples reinforced with kraft pulp. The addition of PP fibres favoured the maintenance of toughness after ageing. Accelerated carbonation promoted the densification of the composites reinforced with sisal organosolv + PP fibres.

  13. Native peoples’ relationship to the California chaparral

    Ethnographic interviews and historical literature reviews provide evidence that for many tribes of California, chaparral plant communities were a rich source of food, medicines, and technologies and that they supplemented natural fires with deliberate burning of chaparral to maximize its ability to produce useful products. Many of the most important chaparral plant species used in the food and material culture have strong adaptations to fire. Particularly useful were many annual and perennial herbs, which proliferate after fire from seed and bulb banks, shrub resprouts that made superb cordage and basketry material, as well as animals that were more readily caught in postfire environments. The reasons for burning in chaparral are grouped into seven ecological categories, each relying on a known response to fire of the chaparral community. The authors posit that tribes employed intentional burning to maintain chaparral in different ages and size classes to meet diverse food and material needs, tracking the change in plant and animal abundance and diversity, and shifts in shrub architecture and habitat structure during the recovery of the chaparral community. Areas were burned in ways designed to create a mosaic of open grassland and recently burned, young and mature stands of chaparral with different combinations of species and densities. This management conferred on chaparral plant communities a degree of spatial, structural, successional, and biotic diversity that exceeded what would have been the case in the absence of human intervention. These impacts are still evident on contemporary landscapes.

  14. Agronomic and economic potential of sweet sorghum and Kenaf: Preliminary results of the California Industrial Crops Demonstration Program

    Sweet sorghum is proving to have excellent potential as a biomass energy crop for the production of fuel alcohol and/or electricity. Its advantages include high biomass and fermentables production per unit area of land, relatively low input requirements, and good suitability to a variety of California growing conditions. Average biomass yield for twelve projects involving nine growers, and eight cultivars was 7.6 bone dry tons per acre (bdt/ac) (17 t/ha) at an average cost of production of $58/bdt ($64/t), ready for harvest. With an ethanol yield of 89 gal/bdt (371 L/t), feed stock costs would be about $0.65/gal ($0.17/L). Improved crop yields at reduced costs can be expected in the future. Kenaf is a potential paper pulp and fiber feed stock which produces a long bast fiber and a short- fiber core material. About 30% of the stem material is long fiber, and the remaining 70% is short fiber. The current cost of production, given demonstration project yields of 4 bdt/ac (9t/ha) is about $222/bdt ($245/t), and available higher-value uses command prices of $300/bdt ($330/t) for long fiber for cordage and $160/bdt ($175/t) for core material as poultry litter, precluding its use directly as an energy feed stock. However, reusing the poultry litter core material for energy production may be economically feasible. This material may be obtained for about $15/bdt ($17/t), and with an ethanol yield of 34 ga/bdt (142 L/t), feed stock cost may be about $0.44/gal ($0.12/L)

  15. Are osseous artefacts a window to perishable material culture? Implications of an unusually complex bone tool from the Late Pleistocene of East Timor.

    We report the discovery of an unusually complex and regionally unique bone artefact in a Late Pleistocene archaeological assemblage (c. 35 ka [thousands of years ago]) from the site of Matja Kuru 2 on the island of Timor, in Wallacea. The artefact is interpreted as the broken butt of a formerly hafted projectile point, and it preserves evidence of a complex hafting mechanism including insertion into a shaped or split shaft, a complex pattern of binding including lateral stabilization of the cordage within a bilateral series of notches, and the application of mastic at several stages in the hafting process. The artefact provides the earliest direct evidence for the use of this combination of hafting technologies in the wider region of Southeast Asia, Wallacea, Melanesia and Australasia, and is morphologically unparallelled in deposits of any age. By contrast, it bears a close morphological resemblance to certain bone artefacts from the Middle Stone Age of Africa and South Asia. Examination of ethnographic projectile technology from the region of Melanesia and Australasia shows that all of the technological elements observed in the Matja Kuru 2 artefact were in use historically in the region, including the unusual feature of bilateral notching to stabilize a hafted point. This artefact challenges the notion that complex bone-working and hafting technologies were a relatively late innovation in this part of the world. Moreover, its regional uniqueness encourages us to abandon the perception of bone artefacts as a discrete class of material culture, and to adopt a new interpretative framework in which they are treated as manifestations of a more general class of artefacts that more typically were produced on perishable raw materials including wood.
