In biological anatomy, commonly referred to as the mouth, under formal names such as the oral cavity, buccal cavity, or in Latin cavum oris, is the opening through which many animals take in food and issue vocal sounds. It is also the cavity lying at the upper end of the alimentary canal, bounded on the outside by the lips and inside by the pharynx and containing in higher vertebrates the tongue and teeth. This cavity is also known as the buccal cavity, from the Latin bucca ("cheek").
Some animal phyla, including vertebrates, have a complete digestive system, with a mouth at one end and an anus at the other. Which end forms first in ontogeny is a criterion used to classify animals into protostome and deuterostome.
In the first multicellular animals there was probably no mouth or gut and food particles were engulfed by the cells on the exterior surface by a process known as endocytosis. The particles became enclosed in vacuoles into which enzymes were secreted and digestion took place intracellularly. The digestive products were absorbed into the cytoplasm and diffused into other cells. This form of digestion is used nowadays by simple organisms such as Amoeba and Paramecium and also by sponges which, despite their large size, have no mouth or gut and capture their food by endocytosis.
Do it yourself, also known as DIY, is the method of building, modifying, or repairing something without the direct aid of experts or professionals. Academic research describes DIY as behaviors where "individuals engage raw and semi-raw materials and component parts to produce, transform, or reconstruct material possessions, including those drawn from the natural environment (e.g. landscaping)". DIY behavior can be triggered by various motivations previously categorized as marketplace motivations (economic benefits, lack of product availability, lack of product quality, need for customization), and identity enhancement (craftsmanship, empowerment, community seeking, uniqueness)
The term "do-it-yourself" has been associated with consumers since at least 1912 primarily in the domain of home improvement and maintenance activities. The phrase "do it yourself" had come into common usage (in standard English) by the 1950s, in reference to the emergence of a trend of people undertaking home improvement and various other small craft and construction projects as both a creative-recreational and cost-saving activity.
Mel Rosenberg (born Melvyn Rosenberg, 12 November 1951 in Winnipeg, Canada) is a microbiologist best known for his research on the diagnosis and treatment of bad breath (halitosis).
Mel Rosenberg (Hebrew: מל רוזנברג) was born in Winnipeg, Canada in 1951. He grew up in Ottawa and immigrated to Israel in 1969. He received his Bachelor of Science from Hebrew University (1973) and went on to pursue both his Masters of Science (1975) and Ph.D. (1982) at Tel Aviv University.
Rosenberg performed his Ph.D. research in the field of petroleum microbiology, under the supervision of Eugene Rosenberg and David Gutnick. His first publication as a graduate student, on the adhesion of microorganisms to oil droplets (1980), became the most highly cited publication of FEMS Microbiology Journal and a "Citation Classic" by the Science Citation Index of 1991.
After receiving his doctorate in microbiology, Rosenberg held various faculty academic positions at the Sackler Faculty of Medicine and Goldschleger School of Dental Medicine at Tel Aviv University, and has received honorary appointments at the University of Rochester, University of Pennsylvania, University College London (Eastman Dental Hospital) and University of Toronto.
