The coarse particles produced a naturally less dense material while the fine grade of shiv a naturally more dense material

In all cases the anisotropic internal structure of the material accounts for the clear variation in both mechanical and thermal properties of the material with testing direction. This is found to be most consistent in the thermal conductivity with a significantly lower thermal conductivity for all variations of hemp-lime in the parallel loading direction. As the…

The sides of the insulations were sealed with wax with aluminium foil on top to achieve unidirectional moisture flow

The MBV was calculated as mass change, Dm, per m2 and per DRH , based on the mean of last three cycles once dynamic equilibrium was attained. The dynamic equilibrium was considered to be attained when the change in mass, Dm , was less than 5% between the last three cycles. Two tests were carried…

Marijuana users also did not differ on total marijuana use episodes or lifetime dependence symptoms

The current findings of greater openness in marijuana users also fit within the framework put forth in studies of marijuana use motives. Specifically, out of five putative motives for marijuana use , highest endorsements have been reported for those that require openness, such as the enhancement motive , followed by social then expansion motives. Future studies are needed to directly examine…

A joint-year is defined by a history of smoking one joint per day times the number of years smoked

Natural fibers are semi-crystalline materials composed generally of an amorphous part basically consisting of the macromolecules of lignin and hemicellulose and a crystalline portion of cellulose. The X-ray diffractograms of treated and untreated hemp fibers are indicated in Fig. 3, they show the presence of peaks characteristic to cellulose molecule located at , 15.2° and 16.6°,correspond respectively…

Super-critical carbon dioxide is most commonly used for CBD due to its much milder supercritical condition

There are also some reports of CBD extraction using polar and non-polar mixed solvents for increased oil yield.However,mixed solvents sometimes result in more impurities and more complicated post processes that are needed.By principle,super-critical fluid is any substance at a temperature and pressure above its critical points but below the pressure required to compress it into solids.Under supercritical…

A measure of consumer concern over roadside drug testing was used to evaluate consumer perception of this association

Exclusion of a large portion of the original study sample for not having knowledge of hemp food’s recently legal status was regarded by the researchers as one indication of the early stage of diffusion of hemp food throughout the Australian population.The findings here,however,may indicate that marketing and conveyance of consumer information might be lacking and diffusion is…

There is now an urgent need for color tests that can differentiate between hemp and marijuana

CBD is also known for these beneficial properties but is non-psychoactive, so it does not give a person a “high” when used. Typically, hemp is CBD-rich containing low concentrations of THC causing its THC:CBD ratio to be below 1. Cannabis is considered marijuana when it has a concertation of total Δ9 – THC ≥ 0.3%…

Samples were stored in polythene bags in a desiccator for subsequent analyses and future studies

Only two major positions of the stem were examined because we observed a large variation in the anatomical traits of the hemp stem from the bottom section to the top section during preliminary analyses using one genotype. Immediately after harvest, the stems of each hemp genotype were cut at two stem heights: sections from internodes…

Different initial lengths of HF were obtained using automatic milling and manual cutting

Depending on the fiber and polymer type, composition, treatment, processing conditions or the model used to determine this critical length, different Lc values were reported. As an example, Lc values ranging from 0.65 to 3.2mm were found for PP/HF composites using different methods. NF dimensions and mechanical properties of the composites are strongly influenced by the…

Mixing such kind of natural fibers into soil was an eco-friendly method comparing to artificial construction materials

Beyond 20% the homogenization of the mixture being more difficult, the fibers are not all linked to each other by the matrix; this discontinuity of the fibers and the non-homogeneity which leads to the agglomeration of fibers has been detected by the scanning electron microscopy in Fig. 8c, showing an area where the fibers were agglomerated…
