Caracteriza??o de minérios: uso do Magstream-Model 100, suas vantagens e limita??es

Abstract: this paper discusses the importance of mineral characterization as a support to understand their behavior in mineral processing and in the control of the processes and quality of the products obtained. also presented is a brief review on the main techniques used in minerals characterization, including the procedures for minerals separation from an ore. special attention was given to the technique of mineral separation from an ore according to their specific gravities using a device called magstream-model 100. it is shown that the magstream process, which involves the use of a magnetic fluid as a medium for mineral separation, a magnetic field and a rotation speed system, offers advantages compared to the heavy liquids technique. however, the magstream process leads to changes on mineral surface properties, imparting to them different flotation behaviors. this fact is considered a limitation for its use when further studies with the minerals involve surface properties.

Abstract: O presente trabalho discute a importancia da caracteriza o de minérios como suporte para o entendimento do comportamento de seus minerais frente a processos de tratamento de minérios, controle de processos e controle da qualidade dos produtos obtidos. é, também, apresentada uma breve revis o da literatura sobre as principais técnicas de caracteriza o, incluindo aquelas utilizadas para a separa o de minerais de um minério. Especial aten o foi dada à técnica de separa o de minerais de um minério, utilizando um equipamento chamado Magstream-Model 100. O trabalho mostra que o processo Magstream, que envolve o uso de fluido magnético como meio separador, campo magnético e um sistema de rota o, oferece vantagens em rela o a outras técnicas, como, por exemplo, a de líquidos densos. Entretanto o processo utilizado pelo Magstream leva a mudan as em propriedades de superfície dos minerais, modificando seus comportamentos frente à flota o. Esse fato foi considerado como uma limita o de seu uso, quando estudos posteriores com os minerais processados no Magstream envolvem propriedades de superfície.

Abstract: the authors report 11 cases of congenital disproportion of fibers, confirmed through clinical and complementary examinations. in these 11 cases early fibrotendinous retractions were frequent and ck proved to be high. at muscle biopsy histochemistry revealed a selective atrophy of type i fibers. this is a rarely frequent congenital dystrophy, of slow progression and benign evolution.

Abstract: myotonia is the phenomenon of decrease of muscular relaxation rate, after either a contraction or a mechanical or electrical stimulus. congenital myotonias are hereditary affections and do not present muscular dystrophy. the current trend is to group them as ionic channels diseases, together with the periodic paralysis.the authors accompanied the cases of seven patients, six males and one female, with ages ranging from 16 to 48 years (average 27 years) and onset of symptons between 1 and 10 years (average 5 years). these patients presented a myotonic phenomenon unleashed by intensive contraction and global muscular hypertrophy. three patients were diagnosed as cases of becker type generalized myotonia because they presented a recessive autosomic heredity and/or transient episodes of muscular weakness. two patients fitted the description of thomsen congenital myotonia, with a pattern of dominating autosomic heredity and/or absence of weakness episodes or worsening factors for their condition.two patients presented fluctuating myotonia, which became worse in cold weather or at potassium intake. the clinical diagnosis was confirmed through complementary tests (electroneuromyography, muscle biopsy and dna study). each of the patients made use of different drugs, in the search of optimal lessening of their myotonia. there were five reports of amelioration with the use of diphenilhydantoine; one report with the use of carbamazepine; three reports with the use of acetazolamide; one report with the use of a calcium channel blocker; one report with the use of a beta-adrenergic; one report with the use of thiazide; and none with the use of quinidine/procainamide.

Abstract: objective: social anxiety disorder is the most common anxiety disorder. the condition has a chronic course usually with no remission and is frequently associated with significant functional and psychosocial impairment. the brazilian medical association, with the project named diretrizes ('guidelines', in english), endeavors to develop diagnostic and treatment protocols for the most common disorders. this work presents the most relevant findings regarding the guidelines of the brazilian medical association concerning the diagnosis and differential diagnosis of social anxiety disorder. method: we used the methodology proposed by the brazilian medical association for the diretrizes project. the search was performed on the online databases medline (pubmed), scopus, web of science, and lilacs, with no time restraints. searchable questions were structured using pico format (acronym for "patient or population"; "intervention, indicator or exposition"; "control or comparison" and; "outcome or ending"). results: we present data regarding the clinical manifestations of social anxiety disorder, impairments and implications related to the condition, differences between the generalized and specific subtypes, and the relationship with depression, drug dependence and abuse, and other anxiety disorders. additionally, the main differential diagnoses are discussed. conclusion: the guidelines are intended to serve as references to the general practitioner and the specialist as well, facilitating the diagnosis of social anxiety disorder.
