After 1000 hours of exposure to UV radiation plus condensation, the composites lost almost 30% of their intrinsic tensile modulus. The reduction in tensile modulus is more gradual for composites exposed to UV radiation only. After 1000 hours of exposure to UV radiation, the composites lost approximately 30% of their intrinsic modulus. However the loss…

The large number of test trials can produce fatigue even without exposure to marijuana
Moreover, we have used the model to detect subspecies differences in the maze performance of rats and to characterize the learning deficits in honey bees exposed to agro chemicals.The remainder of this article describes the mathematical foundation of our model and finishes with an example of how the model is used in practice. We would…
The presented work investigates the properties of fibers extracted from the bast of Cola lepidota stem
This use is justified by their durability in the textile field, their availability and their specific properties. However, with the increase of demand in green materials combined to the decrease of growing space for these common plant fibers, and the race towards new tropical species which are accessible and at lower cost, some recent scientific…
The aim of the present study is to develop a functional and biodegradable ECB for agriculture applications
Many essential oils, such as garlic, oregano, cinnamon, thyme, basil, eucalyptus,rosemary, peppermint, etc., have been demonstrated to show antimicrobial activity . Therefore, these natural products are an alternative to replace synthetic chemical pesticides .The biological activity of these oils can be lost by volatilization of active components or their degradation by act of high temperatures,…
The standardization process consisted of taking the z -scores of each variable in each year
Following recruitment, parents and adolescents completed self-administered questionnaires on an annual basis. These were completed in a private setting, such as their homes, at an office, or an another convenient location. The questionnaires included extensive questions about stressful life events, depressive symptoms,and substance use using validated scales from previous research studies-. The sample included members…
Marijuana use is described by a frequency variable over the last three months
See and who also show that there is a higher risk of failing to complete high school or post-secondary school among cannabis users who start using early.Furthermore,like many other researchers, claim that early and frequent use of marijuana has a significant negative effect on psychological health. Shubart et al. showed that individuals who start using…
It is interesting to note that they found similar ratios to induce and grow callus
Additionally, few studies have been conducted for determining optimal mineral salts or hormone formulations for Industrial Hemp. Feeney and Punja used the MB5D1K medium formulation and it was shown to promote substantial callus growth. The MS salts medium formulated by Murashige and Skoog was originally used to generate callus growth in tobacco for a study…
Some herbicides and pathogens interact synergistically, resulting in increased weed control efficacy
A minooxyacetate was patented as a herbicide in 1964 .This compound is an in vitro inhibitor of phenylalanine ammonia-lyase,phenylalanine transaminase , other transaminases, and ethylene production in plants . In a major study, AOA was found to be a potent inhibitor of all plant transaminases tested.AOA inhibits alanine aminotransferase competitively with amino acid substrates and…
Cannabis abuse might increase the risk for psychosis by modifying the genetic expression of the CB1 receptor
In fact, studies have shown a correlation between genetic polymorphism of the CB1 receptor and schizophrenia, suggesting that gene variants may confer susceptibility to this disorder.Chronic cannabis consumption results in an increase in dopamine concentrations in the mesolimbic regions of the brain and a decrease in dopamine concentrations in the prefrontal cortex which mimics the…
Succinic acid is among the Department of Energy’s top value-added chemicals from biomass
Bioherbicides are microbes and/or microbial phytotoxins used to control weeds. This approach to weed control, has continued, with world-wide efforts as evidenced in several books and reviews – dedicated to bioherbicides. In order for bioherbicide usage to become more predictable, effective and acceptable, it is necessary to maximize the ability of a bioherbicide to infect,…
