Abstract: the species coffea arabica is responsible for 70% of the world coffee production. the majority of cultivars has a narrow genetic origin, being derived basically from two old cultivars: tipica and bourbon. this investigation was carried out aiming at the characterization of selected cultivars of the instituto agronomico according to standard descriptors. thirty five morphological or technological traits of canopy, leaves, flowers, fruits or seeds and three agronomic traits were evaluated in twenty nine cultivar lines of the current breeding program. the variables plant height, fruit color, leaf rust resistance and earliness are sufficient for an efficient identification of groups of cultivars. the color of young leaves and plant diameter are important descriptors for discriminating cultivars of the mundo novo group, but they could not identify cultivars of the catuaí vermelho, catuaí amarelo and icatu vermelho groups.
Study of simple sequence repeat markers from coffee expressed sequences associated to leaf miner resistance
Pinto, Fernanda de Oliveira;Maluf, Mirian Perez;Guerreiro-Filho, Oliveiro;
Pesquisa Agropecuária Brasileira , 2007, DOI: 10.1590/S0100-204X2007000300011
Abstract: the objective of this work was to identify expressed simple sequence repeats (ssr) markers associated to leaf miner resistance in coffee progenies. identification of ssr markers was accomplished by directed searches on the brazilian coffee expressed sequence tags (est) database. sequence analysis of 32 selected ssr loci showed that 65% repeats are of tetra-, 21% of tri- and 14% of dinucleotides. also, expressed ssr are localized frequently in the 5'-utr of gene transcript. moreover, most of the genes containing ssr are associated with defense mechanisms. polymorphisms were analyzed in progenies segregating for resistance to the leaf miner and corresponding to advanced generations of a coffea arabica x coffea racemosa hybrid. frequency of ssr alleles was 2.1 per locus. however, no polymorphism associated with leaf miner resistance was identified. these results suggest that marker-assisted selection in coffee breeding should be performed on the initial cross, in which genetic variability is still significant.
Genetic diversity of cultivated Coffea arabica inbred lines assessed by RAPD, AFLP and SSR marker systems
Maluf, Mirian Perez;Silvestrini, Milene;Ruggiero, Luciana Machado de Campos;Guerreiro Filho, Oliveiro;Colombo, Carlos Augusto;
Scientia Agricola , 2005, DOI: 10.1590/S0103-90162005000400010
Abstract: one of the greatest problems in coffea arabica breeding is identifying precisely any inbred line, based only on botanical and agronomical descriptors, because of the reduced genetic variability of the species, close pedigree origin, which results in small phenotypic variation. recently, molecular markers have been used for plant germplasm characterization and identification in several commercial species. this work evaluates the reliability of three marker systems: rapd, aflp and ssr, to characterize the genetic variability of commercially-used coffea inbred lines developed by the instituto agron?mico (iac), and their potential for cultivar identification. all methods identified polymorphisms among the cultivars. the genetic diversity recognized by the methods is very similar, although is very narrow. rapd and ssr marker systems grouped more efficiently the evaluated cultivars according to parental origin. none of the methods allowed inbred line identification. therefore for varietal protection, it would be necessary using a combination of botanical, agronomical and molecular markers descriptors for precise cultivar identification.

Revista de Nutri??o , 2006, DOI: 10.1590/S1415-52732006000100002
Abstract: objective: the aim of this study is to describe the consumption of protective and promotive foods in cardiovascular diseases among public employees according to level of education and family income. methods: an epidemiologic investigation was carried out with public employees of state offices in s?o paulo city, both sexes and aged up 18th on utilizing random sampling weighted (n=1 271) select from a total of 4 665 persons. information about socioeconomic characteristics, lifestyle and the food consumption, as well as referred to morbidity was obtained. food frequency questionnaire was used to collect information about food habits. results: risk factors such as sedentary lifestyle (88%), overweight/obesity (36%), smoking status (27%) and cardiovascular diseases (30%) were verified. the mean consumption of foods that promote cardiovascular diseases, that is, saturated fatty acids, sodium and sugars, was statistically higher among individuals with a low level of education (elementary school) and a family income of up to 3 minimum wages. the mean consumption of protective foods, such as dietary fiber, vitamins, minerals, polyunsaturated and monounsaturated fatty acids and phytochemicals was statistically higher among those with higher education (college degree) and a family income of more than 6 minimum wages. conclusion: individuals with a low level of education (elementary school) and a family income of up to 3 minimum wages consume more foods that promote cardiovascular diseases. they also presented other associated risk factors more frequently. intervention programs must prioritize this segment of the population.
Paleoamericans in Northeast Argentina  [PDF]
Daniel Loponte, Mirian Carbonera
Archaeological Discovery (AD) , 2017, DOI: 10.4236/ad.2017.52005
Abstract: In this paper, we present a brief synthesis of the record of Fell or Fishtail points found in northeast Argentina, including the first two records for Misiones province. To date, 11 pieces have been identified in the region, which demonstrate techno-morphological similarities with specimens recovered in different areas of South America, which are linked to Paleoamerican groups of the Pleistocene-Holocene boundary. Although these points are still scarce in this area, this is probably due to the lack of research and issues related to archaeological visibility. These new records increase the density of findings of these early hunter-gatherers on the South American Atlantic slope.
Efectos del tiempo de transporte de novillos previo al faenamiento sobre el comportamiento, las pérdidas de peso y algunas características de la canal
Archivos de medicina veterinaria , 2000, DOI: 10.4067/S0301-732X2000000200003
Abstract: the effects of 4 road transport times (3, 6, 12 and 24 hr) of steers before slaughter on behaviour patterns, live and carcass weight losses, and some carcass characteristics such as dressing yield, frequency and grade of bruising, ph and muscle colour were evaluated. two experiments were carried out, one in autumn-winter (oi) and another in spring-summer (pv), with a total of 139 steers of the friesian breed, all of similar age, live weight and fat cover. two lorries of similar structure and capacity were used, giving a space allowance of 1m2 for every 500 kg liveweight; according to the weight of the steers this was equivalent to 17 or 18 animals per load, and each load corresponded to one treatment. the steers were weighed on the farm just before loading, at their arrival at the slaughterhouse and prior to slaughter (after 12 +/- 1 hr lairage). the carcasses were weighed immediately after slaughter; ph and colour (hunterlab) were measured on the longissimus thoracis muscle, 24 h after slaughter. descriptive statistics, an analysis of variance and tukey test were used to determine differences between treatments within each experiment. weight losses during transport were 6.5a; 5.0b; 6.0a and 10.5c% in oi; and 4.6a; 7.3b; 8.9c and 11.9d % in pv, for 3, 6, 12 and 24 hours, respectively (p 0.05). no losses in terms of carcass yield were registered due to longer transport times. a higher overall number of bruises was found in the steers transported for 24 hours. two animals went down in journeys of 12 hours and 7 animals went down in journeys of 24 hours, whilst no steers fell when transported for 3 or 6 hours. the mean ph found in the carcasses of steers transported for 3, 6, 12 and 24 hr respectively was 5.5a, 5.6a, 5.6a and 5.8b in oi; and 5.9a, 5.6b, 5.6b and 5.7b in pv (p 0.05). mean colour lightness (l) of longissimus thoracis surface was 28.5a, 27.5ab, 26.2ab and 24.5c in oi and 23.7a, 25.9b, 26.1b and 25.8b in pv with 3, 6, 12 and 24 hr transport, respectively (
Efectos del tiempo de transporte de novillos previo al faenamiento sobre el comportamiento, las pérdidas de peso y algunas características de la canal Effects of transport time of steers before slaughter on behaviour, weight loss and some carcass characteristics
Archivos de medicina veterinaria , 2000,
Abstract: Se evaluaron los efectos de cuatro tiempos de transporte (3, 6, 12 y 24 h) de novillos en camión sobre el comportamiento animal, las pérdidas de peso vivo y algunas características de la canal como rendimiento centesimal, frecuencia y grado de contusiones, pH y color muscular. Se realizaron dos experimentos, uno en oto o invierno (OI) y otro en primavera verano (PV), con 139 novillos Frisón Negro, de similar edad, peso y cobertura grasa. Se utilizaron dos camiones de similar estructura y capacidad y una densidad de carga equivalente a 500 kg de peso vivo por m2 , lo que correspondió a 17 ó 18 novillos por camionada, correspondiendo cada una a un tratamiento. Los animales fueron pesados en el predio antes de la carga, a la llegada a matadero y previo al faenamiento (12 +/- 1 h de ayuno). Las canales fueron pesadas recién faenadas; el pH y color (Hunterlab) se midieron en el músculo Longissimus thoracis a las 24 horas postmortem. Se usó un dise o completamente al azar en OI y de bloques completos al azar en PV; se realizó un análisis de varianza y las diferencias entre las medias fueron comparadas mediante la prueba de Tukey, para las distintas variables dentro de cada experimento por separado. Las pérdidas de peso durante el transporte fueron de 6,5a; 5,0b; 6,0a y 10,5c % en OI y de 4,6a; 7,3b; 8,9c y 11,9d % en PV para 3, 6, 12 y 24 horas de transporte respectivamente(P0,05). No hubo disminución del rendimiento centesimal de las canales debido al mayor tiempo de transporte. Se observó un mayor número total de contusiones en los novillos transportados por 24 horas. Se registraron dos animales caídos en el transporte de 12 h y siete en el transporte de 24 h y ninguno en los grupos de 3 y 6 h. Los promedios de pH fueron de 5,5a, 5,6a, 5,6a y 5,8b en el experimento OI y de 5,9a, 5,6b, 5,6b y 5,7b en el experimento PV con 3, 6, 12 y 24 h de transporte respectivamente (P0,05). La luminosidad (L) promedio en el Longissimus thoracis fue de 28,5a, 27,5ab, 26,2ab y 24,5c en OI y 23,7a, 25,9b, 26,1b y 25,8b en PV, en los tratamientos con 3, 6, 12 y 24 h de transporte respectivamente (P0,05). Se concluye que el transporte de novillos por 24 h en camión provoca mayores pérdidas de peso vivo, mayor presentación de contusiones y más caídas de animales durante el viaje, que el transporte por menor tiempo, por lo cual debería evitarse. Los resultados para pH y luminosidad (L) indican que tanto los viajes prolongados como los viajes cortos pueden provocar aumentos del pH final y oscurecimiento de la carne, dependiendo de las condiciones particulares de cada viaje The effe

Abstract: the aim of this study was to evaluate cultivars of coffea arabica on the basic of phenology and agronomic attributes a function of the year of production. the phenological attributes were evaluated regarding phenology and percentage of cherry fruits at harvesting time. agronomic traits evaluated included productivity and outturn, type of seeds and grain size. the period between the blooms till the fruits at the beginning of growth did not vary among the coffee trees in the year of production 2004/2005. while in the following year the icatu precoce cultivar presented anticipation of the fruits at the beginning of growth and the 'obat?' cultivar delayed the beginning of the phenological cycle due to the other cultivars studied. the duration of each cycle varied with the year of production and then all the coffee trees in this study could be differentiated on the timing of maturation (early, middle and late). the agronomic attributes (productivity, outturn, type and size of grains), regardless the different cultivars of coffee also varied with the year of production.
Do Surrealismo em David Lynch
Tavares, Mirian;
ARS (S?o Paulo) , 2009, DOI: 10.1590/S1678-53202009000200008
Abstract: surrealism, as the art of its time, proposes a new aesthetics, one that is able to extract the beautiful from the absurd and to establish the swerve from the standard, from which, in fact, the real comes through. through the analysis of some works by david lynch, of breton and soupault's les champs magnétiques, and of breton's poisson soluble, i will attempt to show the relevance of the surrealist designation for the work of the american filmmaker. lynch, like the surrealists, builds a dialectic operation between the rational and the irrational. while operating in the artistic field towards absolute irrationality, lynch does not deny its role in society. it is my belief that the director, as the surrealists, has managed to find a balance between the two ways of being in the world: rational and irrational; by playing with their antitheses. the pleasure of the surrealist game is to go to the depths of the unconscious and return with sufficient material to make a work of art out of it.
O Processo do Rei: a história no palco do cinema
Tavares, Mirian;
ARS (S?o Paulo) , 2011, DOI: 10.1590/S1678-53202011000100008
Abstract: this text discusses the relationship between cinema and theatre starting with the concept of mise en scéne. what joins together and separates these two artistic forms? how has cinema built its own mise en scéne throughout its history while resorting mostly to editing? in order to thoroughly examine the issues raised by this text, i will analyze jo?o mário grilo's movie: o processo do rei (the lawsuit against the king) (1990). based on the lawsuit against dom afonso vi, the director was able to remain faithful to the historical time, the seventeenth century, but at the same time give it a contemporary feel, while exploring eternal and cyclical aspects of the actual story. the cinema, in this movie, works as a stage where the story reveals the directing, which history books habitually hide.
