Considering the average lengths before and after extrusion-injection molding , a reduction of about 2 times in the case of HF, 2.5 times for HF and 4 times for HF was observed. It follows that the reduction of fiber length was greater for longer initial fibers, similar to the results on simple PP/HF composites. Moreover, their […]

Absolute and normalized organ weights were determined on selected tissues
Sixty male rats weighing 224-286 g and 60 female rats weighing 170-218 g were distributed to treatment groups stratified by body weight among the dose and control groups . For both the 14-day and the 90-day studies, body weights were recorded twice during the acclimation period and weekly for the duration of the study. Feed […]
The values of initial adsorption rate and desorption constant varied in function of the copper concentration
Values of ki and correlation coefficients are listed in Table 3,from which it can be seen that the kinetics of copper adsorption on the SHI-W and SHI-C samples followed this model with R2 values higher than 0.95,indicating that intraparticle diffusion was involved in the adsorption process.For these samples,it seems that physisorption played the main role in […]
The addition of heavy metals and Sb significantly affected the growth of all three hemp varieties
Compared with the control,Ni110 significantly reduced the hemp emergence rates for the three hemp cultivars,and Ni220 even completely inhibited germination.Unlike Ni stress,Pb1500 had no marked effects on the emergence rates for any of the hemp cultivars compared with the control,however,Pb3000 significantly increased the rates of Guangxibama and Yunma No.1.Both Sb50 and Sb100 significantly increased the […]
Hemp fibres were used for manufacturing sails and ropes
The increase of phosphorus in the minesoil was in line with organic matter content increase.Soil organic matter plays an important role in P sorption as the main constituent of the soil sorption complex which is responsible for binding of anions in the soil material.Phosphorus leaching can be significantly affected by soil adsorption-desorption properties,and it has […]
Plants with the secondary fibre front just reaching stubble height could be considered ideal
This has implications for the development of multi—purpose cropping systems of hemp.While low quality fibre can be extracted from plants gro̶wn primarily for their seeds or chemicals derived from inflorescences,the extraction of high-quality textile fibres requires harvesting when no seeds or inflorescences are present yet.Fibres from socalled multi—purpose hemp grown for seed and fibres will […]
The RILEM protocol is applied to around 100 g of particles to obtain this parameter
These functional properties are the result of the vegetal aggregates employed in the formulation,whilst mechanical strength is provided by the presence of frame.Numerous studies have been carried out on defining and understanding the properties of the material,or optimising the formulations used.A number of recent studies have looked at the durability and long-term behaviour of these […]
Hemp powder was also tested to investigate the regularity of the results and compare them with shiv
The wett ability of the surface is controlled by the surface chemical composition as well as by the morphology of the mic-structure.Surfaces with a similar chemical composition may have different wett ability behaviour due to the surface topology.In this study,the surface of hemp shiv underwent micro-structural changes via deposition of an organo-functionalised silica coating.Ethanol diluted sol series […]
The mineral element content in hemp seeds is nutritionally interesting
In order to monitor the effects of reformulation and heating treatment on the lipid oxidation of beef burgers, lipid oxidation was measured in all samples, before and after cooking.Significant differences were obtained with the addition of GEs, in both raw and cooked samples.In raw samples, burgers reformulated with chia oil registered higher TBARS values than […]
The least gelation concentration shows the ability of proteins to create a protein network that can entrap water
Among hemp samples, Hemp 5 displayed the highest WHC and HWHC, which could be attributed to its higher protein content and denaturation/aggregation occurring during its double AE-IP. In fact, Hadnađev et al. showed that AE-IP hemp protein showed a two-fold higher WHC than their counterparts obtained through micellisation. On the contrary, it seems that pea […]
