Diferen?as culturais percebidas por brasileiros no uso da língua inglesa no exterior e seu tratamento em livros didáticos
Nogueira, Alessandra Sartori;
Revista Brasileira de Linguística Aplicada , 2012, DOI: 10.1590/S1984-63982012005000018
Abstract: that language and culture are inseparable is broadly accepted in the field of language teaching. this study was thus designed to explore the relation between language and culture by examining anecdotes involving cultural conflicts collected from brazilians in an english-speaking country. here we analyze four (out of seven) questionnaires, for which respondent answers unexpectedly related culture to linguistic issues, such as pronunciation, intonation, grammar, and vocabulary. we then selected, from some textbooks, the linguistic categories detected in the anecdotes, aiming to verify whether there are cultural aspects involved in the way these linguistic issues are presented. our results suggest how the inseparability of language and culture could be explored in classroom when teaching language structure and pronunciation.

Abstract: Apostando na inseparabilidade entre língua e cultura, o presente estudo tem por objetivo explorar um recorte dessa rela o a partir de relatos sobre conflitos culturais vividos por brasileiros em países de língua inglesa. S o aqui explorados quatro de sete questionários obtidos, aqueles cujos respondentes relacionaram cultura a quest es linguísticas como pronúncia, entona o, gramática e vocabulário, algo que era inesperado. Em seguida, selecionamos em alguns livros didáticos as categorias linguísticas abordadas pelos respondentes, a fim de verificar se há aspectos culturais envolvidos no modo como essas quest es linguísticas s o tratadas. Os resultados sugerem instancias em que a rela o língua-cultura pode ser materializada e explorada em sala de aula quando do ensino de estruturas linguísticas e pronúncia.

Abstract: The understanding of the molecular genetics in sensorineural hearing loss (SNHL) has advanced rapidly during the last decade, but the molecular etiology of hearing impairment in the Portuguese population has not been investigated thoroughly. To provide appropriate genetic testing and counseling to families, we analyzed the whole mitochondrial genome in 95 unrelated children with SNHL (53 nonsyndromic and 42 syndromic) and searched for variations in two frequent genes, GJB2 and GJB6, in the non-syndromic patients. Mutations in mtDNA were detected in 4.2% of the cases, including a hitherto undescribed change in the mtDNA-tRNATrp gene (namely, m.5558A>G). We also identified mono- or biallelic GJB2 mutations in 20 of 53 non-syndromic cases and also detected two novel mutations (p.P70R and p.R127QfsX84). Our data further reinforce the notion that genetic heterogeneity is paramount in children with SNHL. 1. Introduction Sensorineural hearing loss (SNHL) is one of the most common disabilities in human, and genetics is an important aspect in research and clinical practice for SNHL. One in 1000 children is born with bilateral SNHL, and 50–70% of them have monogenic causes for their deafness [1]. In addition, 10% of the people over 65 years have SNHL that limits considerably speech communication. Although the etiology is polygenic in most of the cases, with different contribution of ageing and environment, discovering monogenic causes has important clinical implications in terms of better counseling and management. Hereditary hearing loss can be classified into syndromic and nonsyndromic depending on the associated features. Whilst over 400 genetic syndromes have been described in association with mono- or bilateral deafness, syndromic conditions account for about 30% of hereditary congenital hearing loss, whereas the relative contribution to all deaf people is much higher (>70%) for nonsyndromic subtypes [1]. Nonsyndromic sensorineural hearing loss (NSSNHL) is predominantly inherited in an autosomal recessive patterns (DFNB loci) (80%) but can be also autosomal dominantly (DFNA) (15–20%), X-linked (DFN) (2-3%), or maternally (1%) transmitted. A polygenic or multifactorial pattern of inheritance should be postulated for late onset cases of hearing impairment [2, 3]. To date, 134 deafness loci (77 DFNB and 57 DFNA) have been reported, with more than 40 genes cloned [4]. Further heterogeneity is, however, expected to emerge. Mutations in the GJB2 and GJB6 genes on the DFNB1 locus at chromosome 13q11-q12 are responsible for up to 50% of autosomal recessive (AR)

Abstract: vitex megapotamica (tarum?) is a deciduous tree occurring in brazil from minas gerais to rio grande do sul states. in order to characterize fruit and seed morphology and morpho-anatomy of seedlings, fruits of this species were collected and seeds were germinated in the laboratory. seedlings were collected from root protrusion to development of the first pair of eophylls. the fruits were measured and weighed and the number of seeds per fruit counted. fruit and seed morphology were described and illustrated, as well as morphoanatomy of the seedling. the fruit is a 4-locular drupe containing only one or two seeds with a thin layer of endosperm and an axial, foliate embryo. the woody endocarp seems to restrict germination in this species. the seedling has epigeal, phanerocotylar development; elliptical paracotyledons with entire margins, and opposite, simple, elliptical eophylls with serrate margins, and simple multicelullar trichomes. paracotyledons and eophylls have heterogeneous dorsiventral mesophyll, collateral bundle, and anomocytic stomata. the root is polyarc, with parenchymatous cortex; the hypocotyl has glandular and non-glandular trichomes, a distinct collet, and within 20 days it starts secondary growth. many characteristics of seedlings in v. megapotamica are related to the fact that it is a heliophyte.
Resíduos de constru??o e demoli??o: avalia??o de métodos de quantifica??o

Abstract: in this paper, construction and demolition waste generation was estimated by two quantification methods, one direct and other indirect, regarding informal and formal generators. construction area and transformation of the points of water and energy were applied for indirect quantification method. for the direct one, volume of dumping areas associated with informal and formal generators in different regions of municipality were quantified and the mass balance was applied. indirect quantification of informal generators by transformation points of water is not precise. there are evidences that transformation points of energy can be more precise, avoiding costly direct construction and demolition waste quantification method.

Abstract: the utilization of nanostructured materials for development of biosensors is a growing field in medical diagnostics. in this work a glucose biosensor based on bioactive polyglycerol (pgld) and chitosan dendrimers (chd) was developed. pgld and chd were bioconjugated with the enzyme glucose oxidase (gox) to obtain dendrimers with glucose sensing properties. polyaniline nanotubes (panint′s) were used as electron mediator due to their high ability to promote electron-transfer reactions involving gox. the pgld-gox and chd-gox were entrapped in panint′s during template electrochemical polymerization of aniline. the prepared pgld-gox/panint′s and chd-gox/panint′s biosensors exhibit a strong and stable amperometric response to glucose even at a low potential of +100 mv. the based pgld-gox/panint′s and chd-gox/panint′s biosensors showed a good performance in glucose concentrations range in human blood. a comparison of the sensitivities to glucose showed that both biosensors have a linearity range between 0.02 and 10 mm, though pgld-gox/panint′s is more sensitive (10.41 vs. 7.04 na.mm-1). the difference in the biosensor behavior and the high sensitivity of the pgld-gox/panint′s may be due to the specific organization of gox layer at surface of the modifier macromolecule pgld and their distribution in panint′s. the enzyme affinity for the substrate, kmapp remains quite good after gox immobilization on pgld and chd dendrimers and entrapment of the bioconjugates in panint′s.

Abstract: the manifestations occurred in brazil, at the end of the 80's, symbolized the interest in promoting a new meeting between state and society. the government of lula brought new hopes for society and developed a new model of societal management in public administration. the objective of this paper is to analyze whether these practices developed by the brazilian ministry of culture (through the i cultural municipal conference of olinda, occurred in 2005), can characterize a bigger social participation in the management of the politics of national culture. we tried to understand whether these practices are being developed from the participation of both the federated beings and society for the development of a national public politics. we concluded that, although the current government possesses a different speech, not seeming to focus on economic neo-liberalism and searching to accomplish society action, is still far from promoting a full social participation. it's necessary to analyze the brazilian democratic process carefully, since it is not easy to share power.

Abstract: forty six equines were examined, 6 were healthy (g1) and 40 with colic, submitted to laparotomy. twenty were showing lesions on the large intestine (g2) and 20 lesions on the small intestine (g3). the serum concentrations of acute phase proteins: haptoglobin, ceruloplasmin, antitrypsin, transferrin, and - acid glycoprotein before and until 7 days after laparotomy. after centrifugation and fractioning of the samples, the acute phase proteins were individualized by electrophoresis on polyacrylamide gel containing sds-page, and the concentrations were determined by computerized densitometry. the increase was verified on the levels of acute phase proteins from animals with colic, before and after laparotomy, however with higher levels, premature and persistent on animals from g3. the results were due to the process of intestinal inflammation, caused by enteric injury and indicate that the serum protein profile can assist the identifying of the obstructed bowel segment and consequently the elaboration of the prognosis of horses with colic.

Abstract: the oil obtained from brazilian roasted coffee by supercritical co2 extraction shows considerable aromatic properties, mainly composed by five aromatic compounds, 2-methylpyrazine; 2-furfurylalcohol, 2,5-dimethylpyrazine; γ-butyrolactone and 2-furfurylacetate. sensory analyses were used to verify the influence of a mixture of these important classes of aromatic coffee compounds (pyrazines, furans and lactones) and of the roasted coffee aromatic oil on the coffee aroma and flavour of black instant freeze and spray-dried coffee beverages. in the acceptance evaluation of the aroma, the samples prepared with freeze-dried instant coffee without the mixture of volatile compounds (sample 4) were not significantly different from the freeze-dried instant coffee in which the aromatic coffee oil was added (sample 5) and from the sample prepared with freeze-dried coffee in which the mixture of the five volatile was added (sample 3), coincidentally from the same drying process. therefore, sample (3) did not differ from samples prepared with spray dried instant coffee without (sample 1) and to which (sample 2) the mixture of volatile was added. therefore, with respect to this attribute, the addition of this mixture did not interfere in this drink acceptance. taking into consideration the flavor, samples prepared with freeze-dried instant coffee in which the aromatic coffee oil was added (5) and the samples with (3) and without (4) the mixture of the five volatile was added did not differ significantly, however sample (4) did not differ from samples (1) and (2). regarding this attribute, the addition of the aromatic oil of roasted coffee or a mixture of volatile in samples of freeze-dried instant coffee had a better acceptance than those dried by spray dryer (1) and (2). thus, the enrichment of drinks with the aromatic oil of roasted coffee, or even with the mixture of the five components did not influence the consumer acceptance with respect to the aroma, but exerts influence wit

Abstract: the concern about aquatic ecosystems and the potential risk of drinking water contamination by pharmaceuticals have stimulated the study of processes for the efficient degradation of these contaminants, since the conventional treatment have been inefficient on that purpose. the advanced oxidation processes (aops) appear as viable alternatives due to their efficiency on the degradation of different classes of organic contaminants. this review presents an overview of the main aop (o3, h2o2/uv, tio2/uv, fenton and photo-fenton) which have been applied to the degradation of different pharmaceuticals. the main results obtained, intermediates identified and toxicity data are presented.
