Manuais de conduta em mídias sociais e sua contribuição para a democracia digital: um estudo de manuais brasileiros

Information and communication technology have contributed to the realization of the ideals of citizen participation in public decisions, as well as to help in fighting corruption and wrongdoing in government. After all, democracy entails the right to information. The government, in many spheres, has encouraged the responsible use of the internet. Conduct manuals and standards have been published for public segments to direct the responsible use of these tools by their agents. This article aims to determine whether the manuals comply with the principles of digital democracy. Conduct manuals were analyzed in digital media from four Brazilian public organizations: Embrapa; Department of Communication of the Federal Government; Judiciary and Health Department of the Federal District. As a methodology, content analysis, based on criteria focused on transparency and encouraging civic engagement was used.

Tenotomia do músculo flexor digital superficial e desmotomia acessória em equinos: goniometria radiometacarpiana, metacarpofalângica e interfalângica

The purpose of this study was to investigate the effects of the superficial digital tenotomy and the superior check ligament desmotomy on the radio-metacarpal, metacarpophalangeal, proximal and distal interphalangeal angles in horses. Under general anesthesia the superficial digital flexor tenotomy and superior check ligament desmotomy were performed, respectively, on the right and left forelimbs in nine horses. Before surgery and on 15th, 30th, and 60th postoperative days the radio-metacarpal, metacarpophalangeal, and proximal and distal interphalangeal angles were measured by radiographic examination. Tenotomy decreased significantly the metacarpophalangeal angle (mean ± standard deviation: preoperative – 140.7º ± 6.85; 60th day – 128.2º ± 5.93) and increased the distal interphalangeal angle (mean ± standard deviation: preoperative – 172.6 ± 1.87; 60th day – 167.6 ± 1.36). Desmotomy decreased the proximal interphalangeal angle (mean ± standard deviation: preoperative – 180.2º ± 5.43; 60th day- 197.3º ± 8.29). These surgical procedures did not change the radio-metacarpal angle. The superficial digital flexor tenotomy and the superior check ligament desmotomy cause different and significant changes in joint angles distal to the carpus.

Digestibilidade do amido e disponibilidade de ca e p em alimentos energéticos extrusados para a tilápia do nilo (Oreochromis niloticus)

Apparent digestibility coefficients (ADC) of starch and calcium (Ca) and phosphorus (P) apparent availability were evaluated in five cereal grain products and byproducts (corn, wheat meal, rice grain, rice bran and sorghum) for Nile tilapia. Chromic oxide was used as an external digestibility marker. The highest Ca and P apparent availability, respectively, were obtained for rice grain (43.03 and 64.79%), sorghum (39.89 and 58.09%) and corn (22.18 and 19.48%), while rice bran (-31.49 and 3.25%) and wheat meal (5.80 and 1.18%) showed the lowest values. Starch digestibility varied between 99.45 and 95.59% among the evaluated ingredients. This high ADC of starch observed in this study confirms that Nile tilapia is able to efficiently digest and utilize complex carbohydrates.

Determinação da fase lactente-ruminante de cordeiros pela técnica do delta 13C

This study was conducted at University of Marília, São Paulo State, Brazil, aiming to determine the phase of intake transition between exclusively liquid diet (milk) and diet based on milk, grass and/or ration by lambs by δ13C technique. Six Suffolk crossbreeding lambs were distributed in a totally random design (3x2), with two experimental groups and three replications. At the first one, lambs were penned and sucked milk from dams fed with C4 diet. besides, they had access to C3 ration in creep feeding, since their birth. At the second group, lambs were kept on a paddock with Tifton – 85 grass (C4 photosynthetic way) as well as their dams and had access to C3 ration in creep feeding, since their birth. The C3 ration contained soybean meal, ground oat grains, lucerne hay and also mineral salt. The penned lambs’ ration consumption overcame the milk intake at 30-35 days after birth; however, grazing lambs ingested more milk and pasture than ration until 40 days after birth. The δ 13C technique was considered effective on studies of lambs feeding behavior.

Contribution and perspectives of quantitative genetics to plant breeding in Brazil

The purpose of this article is to show how quantitative genetics has contributed to the huge genetic progress obtained in plant breeding in Brazil in the last forty years. The information obtained through quantitative genetics has given Brazilian breeders the possibility of responding to innumerable questions in their work in a much more informative way, such as the use or not of hybrid cultivars, which segregating population to use, which breeding method to employ, alternatives for improving the efficiency of selection programs, and how to handle the data of progeny and/or cultivars evaluations to identify the most stable ones and thus improve recommendations.

QTL detection of yield-related traits of cashew

The identification of quantitative trait loci (QTL) and marker-assisted selection with a view to breeding programs have aroused great interest, including for cashew improvement. This study identified QTL for yield-related traits: nut weight, male and hermaphrodite flowers. The traits were evaluated in 71 F-1 genotypes of the cross CCP 1001 x CP 96. The methods of interval mapping and multiple QTL mapping were applied to identify QTL. Eleven QTL were detected: three for nut weight, four for male flowers and four for hermaphrodite flowers. The QTL accounted for 3.79 to 12.98 % of the total phenotypic variance and had phenotypic effects of -31.81 to 34.25 %. The potential for marker-assisted selection of the QTL hf-2f and hf-3m is great and the phenotypic effects and percentage of phenotypic variation higher than of the others.

Inbreeding depression in castor bean (Ricinus communis L.) progenies

The purpose of this study was to investigate inbreeding depression (DE) in castor bean. From a population derived from the Guarani cultivar, 60 mother plants were sampled. Three types of progenies were obtained from each one: from self-pollination (AU), from crosses (CR) and from open pollination (PL). Grain yield of the progenies was evaluated in two locations. There was a strong interaction of progenies x locations, which led to obtaining estimates within each location. Broad variation was observed in inbreeding depression, with mean values of 6.7% and 13.4%, comparing AU progenies with PL progenies. It was observed that the population has high potential for selecting promising inbred lines. The frequency of mother plants generating progenies with simultaneous high general combination capacity and low inbreeding depression was low. Recurrent selection will increase the occurrence of parent plants associating these two properties, which is necessary for obtaining superior synthetic varieties.

Inheritance of resistance to anthracnose stalk rot (Colletotrichum graminicola) in tropical maize inbred lines

Generation means was used to study the mode of inheritance of resistance to anthracnose stalk rot in tropical maize. Each population was comprised of six generations in two trials under a randomized block design. Inoculations were performed using a suspension of 105 conidia mL(-1) applied into the stalk. Internal lesion length was directly measured by opening the stalk thirty days after inoculation. Results indicated contrasting modes of inheritance. In one population, dominant gene effects predominated. Besides, additive x dominant and additive x additive interactions were also found. Intermediate values of heritability indicated a complex resistance inheritance probably conditioned by several genes of small effects. An additive-dominant genetic model sufficed to explain the variation in the second population, where additive gene effects predominated. Few genes of major effects control disease resistance in this cross. Heterosis widely differed between populations, which can be attributed to the genetic background of the parental resistant lines.
