The use of bio-based building materials such as hemp concrete has increased considerably in France the last few years, due to its hygrothermal and acoustic advantages. Hemp is hygroscopic very sensitive relative humidity. This property responsible for dimensional variations therefore degradation material. To evaluate these variations, 2D 3D imaging techniques can be used. For tools, significant...

Two new species of Phlugidia (Orthoptera: Tettigoniidae: Meconematinae) are described from the Eastern Arc Mountains of Tanzania. P. planicercus Hemp n. sp. occurs in lowland forest at the foothills of the Uluguru Mountains, while P. ob- tusicercus Hemp n. sp. was collected in the Nguru Mountains. A key to Phlugidia species is provided.

The Radar Absorption Material (RAM) method is a coating for reducing the energy of electromagnetic waves received by converting emitted radar into heat energy. Hemp has been studied to have strongest and most stable tensile characteristics 5.5 g/den higher resistance compared other natural fibers. Combining hemp with alumina powder (Al2O3) epoxy resin could provide stealth technology system tha...

Habitat disturbance affects numerous ecosystem components and processes, but its effect on continuous soybean system is less available. Soybean was seeded following six preceding crops, including grain soybean (Glycine max L. Merill.), wheat (Triticum aestivum L.), sugar beet (Beta vulgaris L.), tobacco (Nicotiana tabacum L.), corn (Zea mays L.) and hemp (Cannabis Satia L.), on a Mollisol ...

The benefits of using sustainable building materials are linked not only to the adoption of manufacturing processes that entail reduced pollution, CO2 emissions and energy consumption, but also to the onset of improved performance in the building. In particular, hemp-lime composite shows low shrinkage and high thermal and acoustic insulating properties. However, this material also shows a great...

Abstract The building materials branch of the construction industry is continuously developing due to occurrence new products which seek improve “green” character buildings by using different types wastes. Prefabricated sizes such as blocks, panels, beams and other spatial elements can now be obtained with eco-materials. Concrete most used material in thus it necessary diminish its environmenta...

Integrating bio-resources in materials allows to reduce the environmental impact of building industry. This study deals with fire-retardant treatments, alternative boric acid and ammonium salts solutions, applied hemp fibers for thermal insulation application. The aim is limit energy, sanitary impacts treatment, while optimizing technical performances. A laboratory protocol evaluates flame-reta...

Multiple sclerosis (MS) is an autoimmune disease of central nervous system with inflammatory basis. Experimental autoimmune encephalomyelitis (EAE) is common animal model used in experiments the most for investigating the multiple sclerosis due to many similar aspects. Hemp seed oil possess potential anti-inflammatory properties. In our research we investigated and compared the effect of hemp s...

Hemp-based composites are eco-friendly building materials as they improve energy efficiency in buildings and entail low waste production and pollutant emissions during their manufacturing process. Nevertheless, the organic nature of hemp enhances the bio-receptivity of the material, with likely negative consequences for its long-term performance in the building. The main purpose of this study w...

Focusing on natural fibers are the prominent substitution for synthetic fiber and reinforced into polymer matrices found unique properties such as lightweight, cost-effectiveness, good mechanical wear properties. Incompatibility low adhesive behavior primary drawbacks during fabrication of fiber-bonded matrix composites. The constant weight percentage (10 wt%) sisal hemp is treated with a 5% Na...
