The properties of various kinds of bonds (ionic bond, metallic bond, covalent bond, van der Waals bond) are explained with the aid of simple models. Carbon is discussed with two examples: bonds between 60 atoms that lead to the formation of a three-dimensional molecule known as Buckminsterfullerene, and the alternative sheet-shaped configuration known as graphene, that has recently become the centre of interest. A general theory for finding the energy levels is introduced, relying on Feynman’s coupled wave equations. There is a brief reference to nuclear forces, followed by a discussion of the hydrogen molecule. The relationship between coupling and the splitting of the energy levels is discussed with an analogy to coupled resonant circuits.","PeriodicalId":11632,"journal":{"name":"El Dia medico","volume":"16 1","pages":"2040"},"PeriodicalIF":0.0,"publicationDate":"2018-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75658717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A true congenital deformity (congenital vertical talus) is extremely rare. In children the arch is physiologically flattened with a hypervalgus of the hindfoot. Those feet do not need treatment. If there is no medial recess in the footprint in a child over 3 years of age, then we are talking about a flexible flatfoot. When the load of the foot is more pronounced at the medial rather than at the lateral side, operative treatment can be indicated, such as a lengthening osteotomy of the calcaneum. If the flatfoot is rigid, the reason for it is usually a tarsal coalition. Operative transection of the osseous bridge with fat interposition can solve the problem. Flatfeet may also occur in neuromuscular diseases. Depending on the severity of the deformity, splints can be effective, or--in the more severe cases--operative treatment such as a triple arthodesis can be indicated.","PeriodicalId":11632,"journal":{"name":"El Dia medico","volume":"33 1","pages":"1917-22"},"PeriodicalIF":0.0,"publicationDate":"2010-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77760588","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
