A rather thorough analysis of the scope of the illicit marijuana industry in Canada for is reported at www. At least tonnes t of marijuana were grown in Canada inrepresenting a harvest of 4. Impressively, the species was grown in all 50 states including outdoor seizures in every state except Wyoming!
It was estimated that 8. Marijuana was judged to be the largest revenue producing crop in Alabama, California, Colorado, Hawaii, Kentucky, Maine, Rhode Island, Tennessee, Virginia, and West Virginia, and one of the top five cash crops in 29 other states.
Cannabis contains a seemingly unique class of chemicals, the cannabinoids, of which more than 60 have been described, but only a few are psychoactive. Cannabinoids are produced in specialized epidermal glands, which differ notably in distribution on different organs of the plant high concentrations occur on the upper surface of the young leaves and young twigs, on the tepals, stamens, and especially on the perigonal bract.
Given this distribution, the glands would seem to be protective of young and reproductive above-ground tissues the roots lack glands. The resin is a sticky mixture of cannabinoids and a variety of terpenes.
The characteristic odor of the plant is due to the abundant terpenes, which are not psychoactive. The more important cannabinoids are shown in Fig. In the plant the cannabinoids exist predominantly in the form of carboxylic acids, which decarboxylate with time or when heated.
Technically, the euphoric psychological effects of THC are best described by the word psychotomimetic.
Cannabidiol CBD is the chief non-psychotomimetic cannabinoid. A THC concentration in marijuana of approximately 0. Some cannabinoid races have been described, notably containing cannabichromene particularly in high-THC forms and cannabigerol monomethyl ether in some Asian strains.
The biosynthetic pathways of the cannabinoids are not yet satisfactorily elucidated, although the scheme shown in Fig. Scanning electron micrographs of the abaxial surface of a perigonal bract which envelops the fruit. The resin is synthesized both in stalked and sessile glands.
Multicellular secretory glands of phallic appearancesome broken stalks of these note cellular appearanceand unicellular cystolith hairs claw-like structures are pictured. Some important cannabinoids of cannabis resin.
D9-THC delta-9 tetrahydrocannabinol is the chief intoxicant chemical and predominates in intoxicant strains, while the isomer D8-THC is usually present in no more than trace amounts.
CBD cannabidiol is the chief non-intoxicant chemical, and predominates in non-intoxicant strains; it has sedative effects.
The non-intoxicant CBN cannabinol is a frequent degradation or oxidation product. The non-intoxicant cannabichromene CBC is typically found in trace amounts in intoxicant strains.
The non-intoxicant cannabigerol CBG is considered to be a precursor of the other cannbinoids see Fig. Proposed biosynthetic pathways of the principal cannabinoids after Pate b.

AIM To investigate the tensile strength of plant fibre by using pumpkin stems and compares it to tensile strength of concrete. INTRODUCTION This experiment is carried out to measure the tensile strength of plant fibre and compare ot with the strength of concrete.
Tensile strength is the stress at which a material breaks or permanently 5/5(1). fiber specimen is carried out in the single filament form.
Fefegraph is a very sensitive instrument and is used to measure the tensile strength of fibers in the form of single filament. Sample preparation: Ginger, turmeric and java galangal plants, from various parts of the chosen regions, have been collected.
Essay about Muscle Fatigue Muscle adaptations to the increase in energy demands at the start of exercise Introduction The transition from rest to exercise is associated with a huge upsurge in energy expenditure, due primarily to skeletal muscle contractions (Connett & Sahlin, ).
individual test pieces: the ratios of the highest to lowest tensile strength tested for these hemp fibres were 24, 9, 11, 12, 12, 5, 11, 11, 8, and 21 for the eight types of hemp fibres, respectively. Proprioception (/ ˌ p r oʊ p r i oʊ ˈ s ɛ p ʃ ən, -p r i ə-/ PROH-pree-o-SEP-shən), from Latin proprius, meaning "one's own", "individual", and capio, capere, to take or grasp, is the sense of the relative position of one's own parts of the body and strength of effort being employed in movement.
It is sometimes described as the "sixth sense". In humans, it is provided by.
