Frost-retted hemp fibers were investigated to assess their suitability for composite applications. Chemical analysis of frost-retted highlighted a high amount solubles (pectins) at the surface and low lignin content in that was attributed an unfavorable synthesis cell wall due particularly cold temperature during growth Nordic countries. The tensile properties considered two different scales pe...

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...

Bast fibers, such as ramie, hemp, flax and kenaf, are natural fibers with high specific stiffness strength that have gained increasing attention in recent years. advantageous terms of their biodegradability abundance nature, making them promising candidates for automotive industry, structural composites, pulping textile applications etc. There is a strong desire from industry yielding cellulose...

The use of natural fibers in reinforced composites to produce eco-friendly materials is gaining more attention due to their attractive features such as low cost, low density and good mechanical properties, among others. This work thus investigates the potential of waste abaca (Manila hemp) fiber as reinforcing agent in an inorganic aluminosilicate material known as geopolymer. In this study, th...

The aim of research was to observe and describe biodestructions fabrics that usually used inside a home, estimate the destruction (total number “N” index “K”). samples were placed into thermostat in sterile Petri dishes on moistened filter paper order stimulate microflora occurred fibers. Incubation carried out at +24-28 °C, humidity 90-100% exposed for 8 month. examined with microscope. As res...

The aim of this work is to study the possibility reuse tunnel excavated earth in order elaborate earth-based mortar for rammed reparation. mortars were compared with raw based-mortars, largely used practice. cement was as stabilizer and hemp fibers diminish cracking due shrinkage. mechanical, thermal hydric properties characterized after 28 days. maintained hydrothermal chamber at controlled co...

We previously demonstrated that human embryonic mesenchymal cells derived from the palate (HEMP cells) retain alkaline phosphatase (ALP) content and capacity for collagen synthesis after long-term culture, and their growth is markedly stimulated by epidermal growth factor (EGF). There was a dramatic decrease in ALP content and capacity to synthesize collagen in HEMP cells (HEMP-RV cells) persis...

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...

Cannabis sativa is an economically important source of durable fibers, nutritious seeds, and psychoactive drugs but few economic plants are so poorly understood genetically. Marijuana and hemp were crossed to evaluate competing models of cannabinoid inheritance and to explain the predominance of tetrahydrocannabinolic acid (THCA) in marijuana compared with cannabidiolic acid (CBDA) in hemp. Ind...

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...
