Brick Weed
''Marihuana prensada'' or ''cannabis prensado'' (pressed cannabis or marijuana), also known as ''ladrillo'' (brick weed) or, colloquially, ''paragua'' or ''paraguayo'' is a compressed cannabis cut into blocks that facilitate transport. The largest producer of pressed marijuana is Paraguay, and from there it is exported to Chile, Bolivia, Brazil, Peru, Colombia, Venezuela, and the United States. Other names for this product are ''soko'', ''doko'', ''paraplex macoña'', ''pasto'', ''faso'', ''chamico'', ''enramao'', ''presso'', ''paragua'' or ''Paraguayan brick''. Production In Paraguay, cannabis cultivation occurs mainly in the departments of Alto Paraná, Amambay, Caaguazú, Caazapá, Canindeyú, Concepción, Itapúa and San Pedro. To make pressed bricks, marijuana is harvested, allowed to dry, and compressed in a hydraulic press. Adulterated brick weed Sometimes brick weed is adulterated with other binding substances including industrial glues such as Neoprene, tar, amm ...

Concepción Department, Paraguay
Concepción () is a department of Paraguay. The capital is the city of Concepción. History Throughout history, this department has suffered a great amount of population instability, especially in the times of the colony, due to the advance of the Brazilian "bandeirantes" through the east and the attacks of the Mbayá – Guaicurú natives of Chaco, which, by then, were the lords of that region. During the later years of the colony, it was organized a great campaign to re-conquest the invaded territories with the intention of defending by populating the region and also with the important task of the Jesuit that founded the city of Belén, of creating a Mission with the Mbayá natives, in the year 1760. During the governments of Francia and López, the populating process got stronger and the north area of Paraguay became a territory dedicated to cattle. Francia ordered the construction of the penal colony of Tevego in 1813 in the Concepción department. Once the Par ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neurodegeneration
A neurodegenerative disease is caused by the progressive loss of structure or function of neurons, in the process known as neurodegeneration. Such neuronal damage may ultimately involve cell death. Neurodegenerative diseases include amyotrophic lateral sclerosis, multiple sclerosis, Parkinson's disease, Alzheimer's disease, Huntington's disease, multiple system atrophy, and prion diseases. Neurodegeneration can be found in the brain at many different levels of neuronal circuitry, ranging from molecular to systemic. Because there is no known way to reverse the progressive degeneration of neurons, these diseases are considered to be incurable; however research has shown that the two major contributing factors to neurodegeneration are oxidative stress and inflammation. Biomedical research has revealed many similarities between these diseases at the subcellular level, including atypical protein assemblies (like proteinopathy) and induced cell death. These similarities suggest that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toluene
Toluene (), also known as toluol (), is a substituted aromatic hydrocarbon. It is a colorless, water-insoluble liquid with the smell associated with paint thinners. It is a mono-substituted benzene derivative, consisting of a methyl group (CH3) attached to a phenyl group. As such, its systematic IUPAC name is methylbenzene. Toluene is predominantly used as an industrial feedstock and a solvent. As the solvent in some types of paint thinner, permanent markers, contact cement and certain types of glue, toluene is sometimes used as a recreational inhalant and has the potential of causing severe neurological harm. History The compound was first isolated in 1837 through a distillation of pine oil by the Polish chemist Filip Walter, who named it ''rétinnaphte''. In 1841, French chemist Henri Étienne Sainte-Claire Deville isolated a hydrocarbon from balsam of Tolu (an aromatic extract from the tropical Colombian tree ''Myroxylon balsamum''), which Deville recognized as similar to Wa ...

Joint (cannabis)
A joint (), also commonly referred to as a "doobie" or "doob", is a rolled cannabis cigarette. Unlike commercial tobacco cigarettes, the user ordinarily hand-rolls joints with rolling papers, though in some cases they are machine-rolled. Rolling papers are the most common rolling medium in industrialized countries; however, brown paper, cigarettes or beedies with the tobacco removed, receipts and paper napkin can also be used, particularly in developing countries. Modern papers are manufactured in a range of sizes from a wide variety of materials including rice, hemp, and flax, and are also available in liquorice and other flavoured varieties. Joint size can vary, typically containing between net weight of cannabis. Tobacco is sometimes used in the rolling process. Variations and terminology Although joints by definition contain cannabis, regional differences exist. In Europe, in certain Commonwealth nations, and more recently in North America, joints, or spliffs, typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South America
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent. It can also be described as the southern subregion of a single continent called America. South America is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. The continent generally includes twelve sovereign states: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela; two dependent territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one internal territory: French Guiana. In addition, the ABC islands of the Kingdom of the Netherlands, Ascension Island (dependency of Saint Helena, Ascension and Tristan da Cunha, a British Overseas Territory), Bouvet Island ( dependency of Norway), Pa ...

Trichomes
Trichomes (); ) are fine outgrowths or appendages on plants, algae, lichens, and certain protists. They are of diverse structure and function. Examples are hairs, glandular hairs, scales, and papillae. A covering of any kind of hair on a plant is an indumentum, and the surface bearing them is said to be pubescent. Algal trichomes Certain, usually filamentous, algae have the terminal cell produced into an elongate hair-like structure called a trichome. The same term is applied to such structures in some cyanobacteria, such as '' Spirulina'' and ''Oscillatoria''. The trichomes of cyanobacteria may be unsheathed, as in ''Oscillatoria'', or sheathed, as in ''Calothrix''. These structures play an important role in preventing soil erosion, particularly in cold desert climates. The filamentous sheaths form a persistent sticky network that helps maintain soil structure. Plant trichomes Plant trichomes have many different features that vary between both species of plants and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cannabis Cultivation
This article presents common techniques and facts regarding the cultivation of cannabis, primarily for the production and consumption of its infructescences ("buds" or "flowers"). Cultivation techniques for other purposes (such as hemp production) differ. Botany Cannabis belongs to the genus ''Cannabis'' in the family Cannabaceae. It may include three species, ''Cannabis indica'', '' C. sativa'', and '' C. ruderalis'' (APG II system), or one variable species. It is typically a dioecious (each individual is either male or female) annual plant. ''C. sativa'' and ''C. indica'' generally grow tall, with some varieties reaching 4 metres, or 13 feet. Female plants produce tetrahydrocannabinol (THC) (up to 31% by weight) as the season changes from summer to autumn. ''C. ruderalis'' is very short, produces only trace amounts of THC, but is very rich in cannabidiol (CBD) an antagonist to THC, which may be 40% of the cannabinoids in a plant. C. ruderalis flowers independently ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrocarbons
In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. Hydrocarbons are examples of group 14 hydrides. Hydrocarbons are generally colourless and hydrophobic, and their odors are usually weak or exemplified by the odors of gasoline and lighter fluid. They occur in a diverse range of molecular structures and phases: they can be gases (such as methane and propane), liquids (such as hexane and benzene), low melting solids (such as paraffin wax and naphthalene) or polymers (such as polyethylene and polystyrene). In the fossil fuel industries, ''hydrocarbon'' refers to the naturally occurring petroleum, natural gas and coal, and to their hydrocarbon derivatives and purified forms. Combustion of hydrocarbons is the main source of the world's energy. Petroleum is the dominant raw-material source for organic commodity chemicals such as solvents and polymers. Most anthropogenic (human-generated) emissions of greenhouse gases are carb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bitumen
Asphalt, also known as bitumen (, ), is a sticky, black, highly viscous liquid or semi-solid form of petroleum. It may be found in natural deposits or may be a refined product, and is classed as a pitch. Before the 20th century, the term asphaltum was also used. Full text at Internet Archive (archive.org) The word is derived from the Ancient Greek ἄσφαλτος ''ásphaltos''. The largest natural deposit of asphalt in the world, estimated to contain 10 million tons, is the Pitch Lake located in La Brea in southwest Trinidad (Antilles island located on the northeastern coast of Venezuela), within the Siparia Regional Corporation. The primary use (70%) of asphalt is in road construction, where it is used as the glue or binder mixed with aggregate particles to create asphalt concrete. Its other main uses are for bituminous waterproofing products, including production of roofing felt and for sealing flat roofs. In material sciences and engineering, the terms "asphalt" an ...

Ammonia
Ammonia is an inorganic compound of nitrogen and hydrogen with the formula . A stable binary hydride, and the simplest pnictogen hydride, ammonia is a colourless gas with a distinct pungent smell. Biologically, it is a common nitrogenous waste, particularly among aquatic organisms, and it contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to 45% of the world's food and fertilizers. Around 70% of ammonia is used to make fertilisers in various forms and composition, such as urea and Diammonium phosphate. Ammonia in pure form is also applied directly into the soil. Ammonia, either directly or indirectly, is also a building block for the synthesis of many pharmaceutical products and is used in many commercial cleaning products. It is mainly collected by downward displacement of both air and water. Although common in nature—both terrestrially and in the outer planets of the Solar System—and in wide use, ammonia is both caust ...

Neoprene
Neoprene (also polychloroprene) is a family of synthetic rubbers that are produced by polymerization of chloroprene.Werner Obrecht, Jean-Pierre Lambert, Michael Happ, Christiane Oppenheimer-Stix, John Dunn and Ralf Krüger "Rubber, 4. Emulsion Rubbers" in Ullmann's Encyclopedia of Industrial Chemistry, 2012, Wiley-VCH, Weinheim. Neoprene exhibits good chemical stability and maintains flexibility over a wide temperature range. Neoprene is sold either as solid rubber or in latex form and is used in a wide variety of commercial applications, such as laptop sleeves, orthopaedic braces (wrist, knee, etc.), electrical insulation, liquid and sheet-applied elastomeric membranes or flashings, and automotive fan belts. Production Neoprene is produced by free-radical polymerization of chloroprene. In commercial production, this polymer is prepared by free radical emulsion polymerization. Polymerization is initiated using potassium persulfate. Bifunctional nucleophiles, metal oxides (e.g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
