The d electron count is a chemistry formalism used to describe the electron configuration of the valence electrons of a transition metal center in a coordination complex. The d electron count is an effective way to understand the geometry and reactivity of transition metal complexes. The formalism has been incorporated into the two major models used to describe coordination complexes; ligand field theory which is an application of molecular orbital theory to transition metals and crystal field theory which has roots in VSEPR theory.
High Quality Content by WIKIPEDIA articles! Dabigatran (Pradaxa in Australia, Europe and USA, Pradax in Canada, Prazaxa in Japan) is an oral anticoagulant from the class of the direct thrombin inhibitors. It is being studied for various clinical indications and in some cases it offers an alternative to warfarin as the preferred orally administered anticoagulant ("blood thinner") since it does not require frequent blood tests for international normalized ratio (INR) monitoring while offering similar results in terms of efficacy. There is no specific way to reverse the anticoagulant effect of dabigatran in the event of a major bleeding event, unlike warfarin. It was developed by the pharmaceutical company Boehringer Ingelheim.

High Quality Content by WIKIPEDIA articles! Daidzein structurally belongs to the group of isoflavones. Daidzein and other isoflavone compounds, such as genistein, are present in a number of plants and herbs like the Thai Kwao Krua or Pueraria mirifica, Kudzu or Pueraria lobata, and in food sources such as soybeans and soy products like tofu and textured vegetable protein. Soy isoflavones are a group of compounds found in and isolated from the soybean. Of note, total isoflavones in soy beans are—in general—37 percent daidzein, 57 percent genistein and 6 percent glycitein, according to USDA data. Soy germ contains 41.7 percent daidzein. Besides functioning as antioxidants, isoflavones have been shown to interact with animal and human...
High Quality Content by WIKIPEDIA articles! Darmstadtium is a chemical element with the symbol Ds and atomic number 110. It is an extremely radioactive synthetic element. The most stable known isotope, darmstadtium-281, has a half-life of approximately 11 seconds, but it is possible that this darmstadtium isotope may have an isomer with a longer half-life, 3.7 minutes. Darmstadtium was first created in 1994 by the GSI Helmholtz Centre for Heavy Ion Research in Darmstadt-Arheilgen near Darmstadt, Germany. It was named after the city of Darmstadt, where it was discovered.

The Delhi Bridge, also known as the East Delhi Bridge, is a one-lane, wrought iron Pratt through truss bridge that carries East Delhi Road over the Huron River in Washtenaw County, Michigan. The bridge was built from 1888 through 1890 to replace a wooden span. In 1917, the bridge was severely damaged by a tornado but was rebuilt. After it was closed to traffic in 2005 for being unsafe, the bridge was renovated and reopened in 2009. The bridge is listed on the National Register of Historic Places.
High Quality Content by WIKIPEDIA articles! Delorazepam also known as chlordesmethyldiazepam is a drug which is a benzodiazepine and a derivative of desmethyldiazepam. It is marketed in Italy, where it is available under the trade name EN and Dadumir. Delorazepam (chlordesmethyldiazepam) is also an active metabolite of the benzodiazepine drug cloxazolam. Adverse effects may include hangover type effects, drowsiness, behavioural impairments and short-term memory impairments. Similar to other benzodiazepines delorazepam has anxiolytic,skeletal muscle relaxant,hypnotic and anticonvulsant properties.

High Quality Content by WIKIPEDIA articles! Deoxyribose, more, precisely 2-deoxyribose, is a monosaccharide with idealized formula H-(C=O)-(CH2)-(CHOH)3-H. Its name indicates that it is a deoxy sugar, meaning that it is derived from the sugar ribose by loss of an oxygen atom. Since the pentose sugars arabinose and ribose only differ by the stereochemistry at C2`, 2-deoxyribose and 2-deoxyarabinose are equivalent, although the latter term is rarely used because ribose, not arabinose, is the precursor to deoxyribose.

High Quality Content by WIKIPEDIA articles! Dicopper chloride trihydroxide is the chemical compound with the formula Cu2(OH)3Cl. It is often referred to as tribasic copper chloride (TBCC), copper trihydroxyl chloride or copper hydroxychloride. It is a greenish crystalline solid encountered in mineral deposits, metal corrosion products, industrial products, art and archeological objects, and some living systems. It was originally manufactured on an industrial scale as a precipitated material used as either a chemical intermediate or a fungicide. Since 1994, a purified, crystallized product has been produced at the scale of thousands of tons per year, and used extensively as a nutritional supplement for animals.
High Quality Content by WIKIPEDIA articles! Didymium (Greek: twin element) is a mixture of the elements praseodymium and neodymium. It is used in safety glasses for glassblowing and blacksmithing, especially when a gas (propane) powered forge is used, where it provides a filter which selectively blocks the yellowish light at 589 nm emitted by the hot sodium in the glass, without having a detrimental effect on general vision, unlike dark welder`s glasses. Blocked also is the strong ultraviolet light emitted by the superheated forge gases and insulation lining the forge walls thereby saving the crafters` eyes from serious cumulative damage. (See also arc eye, also known as welder`s flash or photokeratitis.)
