O cromo (Cr) é um elemento metálico do grupo 6 (VIB) da tabela periódica. Anualmente, toneladas desse metal são produzidas pela extração do ferro ou minério de cromita de magnésio (FeCr2O4, MgCr2O4), que é reduzido com carbono para obter o metal. É muito reativo, e somente em condições muito redutoras é em sua forma pura.

Nos anos de 1945 e 1946, dois físicos americanos de forma independentes estudaram mais detalhadamente estes fenômenos dbertos por Rabi. Félix Bloch e colaboradores na Universidade de Stanford e Edward Purcell e colaboradores na Universidade de Harvard , proporcionou que a técnica de RMN fosse usada mais rotineiramente para estudar a composição molecular de amostras.

Aplicações. Originalmente o PMMA era visto como um substituto do vidro e, ainda hoje, ele é muito utilizado em aplicações de envidraçamento e nas indústrias de construção civil, automotiva e de comunicações [4]; sendo processado principalmente por moldagem, injeção ou extrusão [4].

Neural growth factor (NGF) is a neurotrophin with two non-covalently bound monomers. Each monomer has four loop regions with polar amino acid sequences and two β-pleated sheet strands (Mcdonald et al., 1991).Classically, the mature form of the peptide is associated with neural stimulation and survival (Cohen-Cory et al., 1991). A range of receptors may interact with NGF.

Mar 01, 2009· INTRODUCTION. The development of molecular biology was one of the greatest achievements in biological science in the century XX. The discovery of Polymerase Chain Reaction (PCR) brought enormous benefits and scientific developments such as genome sequencing, gene expressions in recombinant systems, the study of molecular genetic analyses, including the rapid …

Money is also called cash or currency. It is used for the exchange of things. In the old days, when people didn’t have money, they exchanged their things with each other by direct negotiation which is called "purchase and sale agreement".. For example: one brought a bag of rice to the market in exchange for a cow or one took a duck or a chicken to the market in exchange for rice or salt, etc.

Prostate cancer is the most common solid organ malignancy affecting men in the United States and Western Europe. Currently, the main diagnostic tools used to look for evidence of prostate cancer include physical examination using digital rectal exam (DRE), serum concentrations of prostate specific antigen (PSA) and biopsy. However, due to the low specificity of PSA in differentiating prostate ...

Aromaticidade é uma propriedade química na qual certos sistemas são mais estáveis do que deveriam ser, são mais simétricos do que se presumia e apresentam característica magnética peculiar. Na verdade os especialistas sabem caracterizar e reconhecer sistemas aromáticos, mas estão longe de um consenso sobre qual a sua origem.

Due to the brittle character of sand is the comminution unproblematic. But it must be kept in mind, that because of its composition it may vary in its abrasiveness. In order to minimize this influence, typically a mill with impact forces is chosen. The FRITSCH Planetary Mills are especially suitable for fast and effective processing.

Gellan gum is a hydrogel-forming polysaccharide when combined with monovalent or divalent cations such as sodium, magnesium, potassium or calcium. Commercially, gellan gums are sold with trace amounts of these cations, which have been proven to affect the gelation and mechanical properties of the resultant hydrogels. A new method based on impedance analysis for determining the gel transition ...
