Raw hemp fibers are alkaline delignified to evaluate the effect of lignin on moisture uptake behavior hemp. Samples subjected absorption/desorption isotherms from 5% 95% relative humidity at three different temperatures (15, 25, and 35°C). The sorption ratio between untreated is lowered by 25%. Hysteresis makes evident greater influence binding low while high humidity, cellulose plays most impo...

In this article, free vibration analysis of variable stiffness composite laminate (VSCL) plates with flat and folded shapes is studied. In order to consider the concept of variable stiffness, in each layer of these composite laminated plates, the curvilinear fibers are used instead of straight fibers. The analysis is based on a semi-analytical finite strip method which follows classical laminat...

This paper presents an antenna of High altitude electromagnetic pulse (HEMP) radiating-wave simulator which expands the testing zone larger than the traditional transmission line simulator. The numerical results show that traverse electramagnetic (TEM) antenna can be used to radiate HEMP simulation radiating wave, but in low frequency band the emissive capability is poor. The experiment proves ...

In greenhouse and field experiments, a mycelial formulation of the fungus Myrothecium verrucaria (IMI 361690) containing 0.20% Silwet L-77 surfactant exhibited high bioherbicidal efficacy against the problematic weed hemp sesbania. Infection and mortality levels of 100% of hemp sesbania seedlings occurred within 48 h after fungal application in the greenhouse. In rice field tests conducted over...

Cannabis (Cannabis sativa L.), commonly known as hemp, is an annual herb belongs to the family Cannabacea. The seeds of this plant have considerable content of oil and unsaturated fatty acids, and its fiber is used in the paper and textile industries. Tetrahydrocannabinol and cannabidiol are main cannabinoid compounds of this plant, which have high importance for their well-known pharmaceutical...

Hemp oil makes an excellent emollient which moisturizes skin and hair. In the old days it had mainly been used to manufacture greenish soft soap and soothing emulsions for skin care. It was also said to bring relief from dandruff and remedy hair loss. In the past years, the renaissance of hemp and the claims of the beneficial effects of its oil have stimulated a great deal of experimentation in...

Colletotrichum tnmmtum NRRL 18434 is a host-specific pathogen of hemp sesbania (Sesbania exaltata), a weed in cotton, soybeans and rice. The bioherbicidal potential of C. tnmmhml microsclerotia (MS) was assessed based on the feasibility of prodUcing and storing microsclerotia and the efficacy of microsclerotia in controlling hemp sesbania. Microsclerotia were produced in highly aerated liquid c...

Wild hemp is one of the most valuable technical plant caused by sexual dimorphism: the differences in rate floras of Kazakhstan.Generally, it is accepted that the of growth and development between male and female most economically advantageous became fromthe plants are large [9]. The male plants tend to flower and cultivation of cultural fibre hemp varieties. The fibre hemp senesce earlier. Als...
