Rachel Lloyd (chemist)
Rachel Lloyd (January 26, 1839 – March 7, 1900) was an American chemist who focused on the chemistry and agriculture of sugar beets (''Beta vulgaris''). She studied at the Harvard Summer School and received her doctorate from the University of Zurich in 1886. She was the first American woman to earn a doctorate of chemistry and the first woman author in a major chemistry journal. She worked as a professor of chemistry and head of the chemistry department at the University of Nebraska-Lincoln. Her work in determining the sucrose concentration of sugar beets helped establish a commercial sugar industry in Nebraska. In 1891, she became the first regularly admitted female member of the American Chemical Society. On October 1, 2014, the Society designated her research and professional contributions to chemistry at the University of Nebraska-Lincoln a National Historic Chemical Landmark.

Quakers
Quakers are people who belong to a historically Protestant Christian set of denominations known formally as the Religious Society of Friends. Members of these movements ("theFriends") are generally united by a belief in each human's ability to experience the light within or see "that of God in every one". Some profess a priesthood of all believers inspired by the First Epistle of Peter. They include those with evangelical, holiness, liberal, and traditional Quaker understandings of Christianity. There are also Nontheist Quakers, whose spiritual practice does not rely on the existence of God. To differing extents, the Friends avoid creeds and hierarchical structures. In 2017, there were an estimated 377,557 adult Quakers, 49% of them in Africa. Some 89% of Quakers worldwide belong to ''evangelical'' and ''programmed'' branches that hold services with singing and a prepared Bible message coordinated by a pastor. Some 11% practice ''waiting worship'' or ''unprogramme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clifton Springs, New York
Clifton Springs is a village located in Ontario County, New York, United States. The population was 2,127 at the 2010 census. The village takes its name from local mineral springs. The Village of Clifton Springs is located primarily in the Town of Manchester, but the eastern part is in the Town of Phelps. The village is southeast of Rochester, NY. :(The area and population reported and analyzed in this article are also reflected in the aggregate values reported for the town as a whole. ''See: Manchester (town), New York.'') History The location was first settled around 1801, and much of the early community endeavors exploited the sulfur springs as a health spa. The village was incorporated in 1859. The development of the area was slow until 1849, when Dr. Henry Foster came looking for a place to begin his water cure. Modern medicine was in its early stages, and it was thought that the sulphur waters together with a strong religious revival could restore many to active a ...

Aromatic Amine
In organic chemistry, an aromatic amine is an organic compound consisting of an aromatic ring attached to an amine. It is a broad class of compounds that encompasses anilines, but also many more complex aromatic rings and many amine substituents beyond . Such compounds occur widely. Aromatic amines are widely used as precursor to pesticides, pharmaceuticals, and dyes. Aromatic amines in textiles Since August 2012, the new standard EN 14362-1:2012 ''Textiles - Methods for determination of certain aromatic amines derived from azo colorants - Part 1: Detection of the use of certain azo colorants accessible with and without extracting the fibres'' is effective. It had been officially approved by the European Committee for Standardization (CEN) and supersedes the test standards EN 14362-1: 2003 and EN 14362-2: 2003. The standard describes a procedure to detect EU banned aromatic amines derived from azo colorants in textile fibres, including natural, man-made, regenerated, and ...

Phenols
In organic chemistry, phenols, sometimes called phenolics, are a class of chemical compounds consisting of one or more hydroxyl groups (— O H) bonded directly to an aromatic hydrocarbon group. The simplest is phenol, . Phenolic compounds are classified as simple phenols or polyphenols based on the number of phenol units in the molecule. Phenols are both synthesized industrially and produced by plants and microorganisms. Properties Acidity Phenols are more acidic than typical alcohols. The acidity of the hydroxyl group in phenols is commonly intermediate between that of aliphatic alcohols and carboxylic acids (their pKa is usually between 10 and 12). Deprotonation of a phenol forms a corresponding negative phenolate ion or phenoxide ion, and the corresponding salts are called phenolates or phenoxides (aryloxides according to the IUPAC Gold Book). Condensation with aldehydes and ketones Phenols are susceptible to Electrophilic aromatic substitutions. Condensation with formald ...

Neuralgia
Neuralgia (Greek ''neuron'', "nerve" + ''algos'', "pain") is pain in the distribution of one or more nerves, as in intercostal neuralgia, trigeminal neuralgia, and glossopharyngeal neuralgia. Classification Under the general heading of neuralgia are trigeminal neuralgia (TN), atypical trigeminal neuralgia (ATN), occipital neuralgia, glossopharyngeal neuralgia and postherpetic neuralgia (caused by shingles or herpes). The term ''neuralgia'' is also used to refer to pain associated with sciatica and brachial plexopathy. Atypical (trigeminal) Atypical trigeminal neuralgia (ATN) is a rare form of neuralgia and may also be the most misdiagnosed form. The symptoms can be mistaken for migraines, dental problems such as temporomandibular joint disorder, musculoskeletal issues, and hypochondriasis. ATN can have a wide range of symptoms and the pain can fluctuate in intensity from mild aching to a crushing or burning sensation, and also to the extreme pain experienced with the more ...

Rheumatism
Rheumatism or rheumatic disorders are conditions causing chronic, often intermittent pain affecting the joints or connective tissue. Rheumatism does not designate any specific disorder, but covers at least 200 different conditions, including arthritis and "non-articular rheumatism", also known as "regional pain syndrome" or "soft tissue rheumatism". There is a close overlap between the term soft tissue disorder and rheumatism. Sometimes the term "soft tissue rheumatic disorders" is used to describe these conditions. The term "Rheumatic Diseases" is used in MeSH to refer to connective tissue disorders. The branch of medicine devoted to the diagnosis and therapy of rheumatism is called rheumatology. Types Many rheumatic disorders of chronic, intermittent pain (including joint pain, neck pain or back pain) have historically been caused by infectious diseases. Their etiology was unknown until the 20th century and not treatable. Postinfectious arthritis, also known as reactive art ...

Jaundice
Jaundice, also known as icterus, is a yellowish or greenish pigmentation of the skin and sclera due to high bilirubin levels. Jaundice in adults is typically a sign indicating the presence of underlying diseases involving abnormal heme metabolism, liver dysfunction, or biliary-tract obstruction. The prevalence of jaundice in adults is rare, while jaundice in babies is common, with an estimated 80% affected during their first week of life. The most commonly associated symptoms of jaundice are itchiness, pale feces, and dark urine. Normal levels of bilirubin in blood are below 1.0 mg/ dl (17 μmol/ L), while levels over 2–3 mg/dl (34–51 μmol/L) typically result in jaundice. High blood bilirubin is divided into two types – unconjugated and conjugated bilirubin. Causes of jaundice vary from relatively benign to potentially fatal. High unconjugated bilirubin may be due to excess red blood cell breakdown, large bruises, genetic conditions s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
