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…

Moisture absorption is another significant disadvantage affecting the mechanical properties of natural fibers

A new way how shives are used in its native form is in combination with lime for the production of construction materials.Due to the high content of carbohydrates,mostly glucose and xylose ,hemp shives can be considered as a potential source of bio-based chemicals,such as furfural,lactic acid,ethanol,etc.However,due to the compact and rigid structure of hemp shives…

Hemp shiv has low density due to its high porosity and it tends to absorb large amounts of water

HIU treatment can reduce the particle size,increase solubility and improve the emulsification characteristics of protein.In Zhao et al.’s study,the solubility,foaming and emulsification of perilla protein isolate were improved after ultrasonic treatment.Meanwhile,the interfacial waves and cavitation bubbles generated by the sound field broke up the oil droplets,reducing the emulsion droplet size.In addition,the mechanical shearing,thermal effects,dynamic stirring and…

The drawing process has the objective to align the fibres and increase their separation level

Moreover,a special care in the stem introduction at the entrance of the scutching machine has to be considered so that the stems are well ordered in a homogeneous manner.As the stems were introduced manually,this was not the case during these first industrial scale trials.In next trials,the stems will be baled using the flax machinery and…

Primary bast fibre cells develop in the primary phloem that is differentiated from the procambium

The neutral form of CBD and THC were extracted fast at the beginning of the extraction,while the CBDA and THCA were found in higher concentration in the late subsequent samples suggesting their lower solubilities.The fractionation of the extracts into two separators was investigated by changing the pressure of 1st separator  on the example of Sample 3.The…

The dry sieving of ground samples was performed using a vertical vibratory sieve shaker for 20 min

We found that the expression levels of five genes  were significantly up-regulated after GA3 treatment for 3 h.In addition,among these 39 CasWRKYs,the transcription levels of four CasWRKYs  were continuously up-regulated in the stem barks under the GA3 stress.The above results suggest that these CasWRKY may be involved in the development of fibers under GA3 stress.Similarly,previous…
