oleochemistry is the study of vegetable oils and animal oils and fats, and oleochemicals derived from these fats and oils or from petrochemical feedstocks through physico-chemical modifications or transformation. first used in the making of soaps, oleochemistry is now part of our daily lives where it is found in a wide variety of sectors like food, cosmetics, pharmaceutical and industrial.
data were assembled using pacbio’s hierarchical genome assembly process hgap , and showed that long-read assemblies revealed a 63-fold improvement in contig size over an illumina-only assembly. another plant genome that was recently published that used long reads in combination with short reads is the improved assembly of the apple genome.
the solvay process or ammonia-soda process is the major industrial process for the production of sodium carbonate. the ammonia-soda process was developed into its modern form by ernest solvay during the 1860s. the ingredients for this are readily available and inexpensive: salt brine and limestone. the worldwide production of soda ash in 2005 has been estimated at 42 million metric tons, which is more than six kilograms per year for each person on earth. solvay-based chemical plants now produce
soil biology is the study of microbial and faunal activity and ecology in soil. soil life, soil biota, soil fauna, or edaphon is a collective term that encompasses all organisms that spend a significant portion of their life cycle within a soil profile, or at the soil-litter interface. these organisms include earthworms, nematodes, protozoa, fungi, bacteria, different arthropods, as well as .
the ongoing worldwide pandemic of coronavirus disease 2019 covid-19 , a new infectious disease caused by severe acute respiratory syndrome coronavirus 2 sars-cov-2 , was first c
by the 1890s, solvay-process plants produced the majority of the world's soda ash. in 1938 large deposits of the mineral trona were discovered near the green river in wyoming from which sodium carbonate can be extracted more cheaply than produced by the process. with the closing of the original solvay, new york plant in 1986, there have been no solvay-based plants operating in north america.
a recent study found the plant is capable of growing in fuel-contaminated soil. in addition, the study discovered the plant is also able to clean the soil, so in the end, it is almost fuel-free. other uses
isatis tinctoria, also called woad /ˈwoʊd/ , dyer's woad, or glastum, is a flowering plant in the family brassicaceae. it is occasionally known as asp of jerusalem. woad is also the name of a blue dye produced from the leaves of the plant. woad is native to the steppe and desert zones of the caucasus,. isatis tinctoria history of woad cultivation invasive and noxious weedhand washing
hand washing, also known as hand hygiene, is the act of cleaning one's hands for the purpose of removing soil, grease, microorganisms, or other unwanted substances. hand washing with soap at 'critical moments' during the day prevents the spread of many diseases, for example diarrhoea and cholera, which are transmitted through fecal–oral route. people can also become infected with respiratory diseases such as influenza or the common cold, for example, if they do not wash their hands before .
hippophae rhamnoides, also known as sea-buckthorn: 277 is a species of flowering plant in the family elaeagnaceae, native to the cold-temperate regions of europe and asia. it is a spiny deciduous shrub. the plant is used in the food and cosmetics industries, in traditional medicine, as animal fodder, and for ecological purposes.
indian ice cream, also known as sxusem pronounced 's-khushem' , is a canadian whipped confection made from soapberries shepherdia canadensis and other various fruits, these have been eaten as a traditional dessert by many first nations peoples. it has been suggested that it was first produced in the interior salish territory of british columbia which was located in the upper basins of the .
biodiesel production is the process of producing the biofuel, biodiesel, through the chemical reactions of transesterification and esterification. this involves vegetable or animal fats and oils being reacted with short-chain alcohols typically methanol or ethanol . the alcohols used should be of low molecular weight.
aphid saliva may inhibit phloem-sealing mechanisms and has pectinases that ease penetration. non-host plants can be rejected at any stage of the probe, but the transfer of viruses occurs early in the investigation process, at the time of the introduction of the saliva, so non-host plants can become infected.
isatis tinctoria, also called woad / ˈ w oʊ d / , dyer's woad, or glastum, is a flowering plant in the family brassicaceae.it is occasionally known as asp of jerusalem.woad is also the name of a blue dye produced from the leaves of the plant. woad is native to the steppe and desert zones of the caucasus, central asia to eastern siberia and western asia per hegi but is now also found in .
hashish, or hash, is a drug made from the resin of the cannabis plant. it is consumed by inhaling from a small piece, typically in a pipe, bong, vaporizer or joint, or via oral ingestion after decarboxylation .as pure hashish will not burn if rolled alone in a joint, it is typically mixed with herbal cannabis, tobacco or another type of herb for this method of consumption.
the prize was awarded to nicolas leblanc for a process which used sea salt and sulfuric acid as the seven trust materials. later a plant of his own was in operation producing 320 tons of soda ash per year. the process, however, is now obsolete and is superseded by the extremely profitable and convenient solvay process. final days
cyperus esculentus is an annual or perennial plant, growing to 90 cm 3.0 ft tall, with solitary stems growing from a tuber. the plant is reproduced by seeds, creeping rhizomes, and tubers. due to its clonal nature, c. esculentus can take advantage of soil disturbances caused by anthropogenic or natural forces. the stems are triangular in section and bear slender leaves 3–10 mm 1/8 to 1/2 .
pears soap was made using a process entirely different from that for other soaps. a mixture of tallow and other fats was saponified by an alkali.clearly, this is currently caustic soda sodium hydroxide , since the ingredients list shows sodium salts of fatty acids, but a chemist reports that in the 1960s, caustic potash potassium hydroxide was used.
