There are several types of trumpet. The most common is a transposing instrument pitched in B♭ with a tubing length of about 148 cm. Earlier trumpets did not have valves, but modern instruments generally have either three piston valves or, more rarely, three rotary valves. Each valve increases the length of tubing when engaged, thereby lowering the pitch.
A musician who plays the trumpet is called a trumpet player or trumpeter.
]]>Distinctions are sometimes made between different categories of veganism. Dietary vegans (or strict vegetarians) refrain from consuming animal products, not only meat but, in contrast to ovo-lacto vegetarians, also eggs, dairy products and other animal-derived substances. The term ethical vegan is often applied to those who not only follow a vegan diet, but extend the vegan philosophy into other areas of their lives, and oppose the use of animals or animal products for any purpose.[4] Another term used is environmental veganism, which refers to the avoidance of animal products on the premise that the harvesting or industrial farming of animals is environmentally damaging and unsustainable.
The term vegan was coined in 1944 by Donald Watson when he co-founded The Vegan Society in England, at first to mean “non-dairy vegetarian” and later to refer to “the doctrine that man should live without exploiting animals.”Interest in veganism increased in the 2000s; vegan food became increasingly available in supermarkets and restaurants in many countries, and several top athletes in endurance sports, such as the Ironman triathlon and the ultramarathon, began to practise veganism and raw veganism.
A 2009 research review indicated that vegan diets tend to be higher in dietary fibre, magnesium, folic acid, vitamin C, vitamin E, iron and phytochemicals, and lower in calories, saturated fat, cholesterol, long-chain omega-3 fatty acids, vitamin D, calcium, zinc and vitamin B12.[8] Well-planned vegan diets appear to offer protection against certain degenerative conditions, including heart disease,[9] and are regarded as appropriate for all stages of the life-cycle by the American Dietetic Association, the Australian National Health and Medical Research Council, and Dietitians of Canada.[10] Because uncontaminated plant foods do not provide vitamin B12 (which is produced by microorganisms such as bacteria), researchers agree that vegans should eat B12-fortified foods or take a supplement.
]]>Allmusic identifies indie rock as including a number of “varying musical approaches [not] compatible with mainstream tastes”. Linked by an ethos more than a musical approach, the indie rock movement encompassed a wide range of styles, from hard-edged, grunge-influenced bands, through do-it-yourself experimental bands like Pavement, to punk-folk singers such as Ani DiFranco.Many countries have developed an extensive local indie scene, flourishing with bands with enough popularity to survive inside the respective country, but virtually unknown elsewhere.
Indie rock has been identified as a reaction against the macho culture that developed in alternative rock in the aftermath of Nirvana’s success. Indie rock is noted for having a relatively high proportion of female artists compared with preceding rock genres, a tendency exemplified by the development of the feminist-informed Riot Grrrl music of acts like Bikini Kill, Bratmobile, 7 Year Bitch, Team Dresch and Huggy Bear.
]]>Honey has had a long history in human consumption, and is used in various foods and beverages as a sweetener and flavoring. It also has a role in religion and symbolism. Flavors of honey vary based on the nectar source, and various types and grades of honey are available. It has also been used in various medicinal traditions to treat ailments. The study of pollens and spores in raw honey (melissopalynology) can determine floral sources of honey.[5] Bees carry an electrostatic charge whereby they attract other particles in addition to pollen, which become incorporated into their honey; the honey can be analysed by the techniques of melissopalynology in area environmental studies of radioactive particles, dust and particulate pollution.
