Abstract: Background. Leishmaniases are diseases with a wide spectrum of clinical manifestations including cutaneous (CL) and visceral (VL) forms. Many factors may affect their occurrence and expansion including environmental, geographic, and social conditions. In the past two decades, Divinópolis, Minas Gerais State, Brazil, has exhibited the potential for a disease outbreak, with the appearance of CL, and VL cases (human and canine). Hence, this study was initiated to monitor public knowledge of the disease. Questionnaires were administered in four neighborhoods (Jardim Belvedere, Esplanada, Danilo Passos I and II) where most of the human and canine cases have been reported. The analyses demonstrated that public knowledge of the disease is sparse and fragmented. A strong perception of the dog as the main reservoir was observed. Five veterinary clinics were evaluated for the presence of canine VL using serological (RIFI and ELISA) and molecular (PCR-RFLP) techniques. This is the first study demonstrating the occurrence of Leishmania infantum in Divinópolis, suggesting a possible urbanization of VL. 1. Introduction Leishmaniases are a group of diseases caused by the protozoan Leishmania (Kinetoplastida: Trypanosomatidae) affecting 12 million people in 88 countries. The disease exhibits a wide spectrum of clinical manifestations ranging from benign cutaneous lesions (CL) to the fatal visceral form (VL) [1]. In Latin America, especially Brazil, both forms are widely distributed and are transmitted by the bite of phlebotomine sand flies (Diptera: Psychodidae) [2]. Wild and domestic reservoirs including foxes, marsupials, rodents, dogs, and cats are the main sources of sand fly infection [3–8]. Many factors may have contributed to VL and CL expansion and urbanization [9], including deforestation [10], human migration [11], vector adaptation [12, 13], drug resistance [14], poverty [15], and social conflicts [16]. As a result of anthropic modifications, VL has been increasingly reported in urban areas of major Brazilian cities including Natal, Teresina, Sobral, and Belo Horizonte [5, 17–20]. The city of Divinópolis, Minas Gerais State, Brazil, has a population of approximately 210,000. It has grown dramatically, with 90.5% of its territory completely urbanized in 2000 [21]. During the 1990s, 135 CL cases were detected by health authorities. Most of those cases were reported in the neighborhoods of Jardim Belvedere, Esplanada, S?o José, Catal?o, and Candelária, all in the vicinity of Mata do Noé forest, where a large area was deforested. More recently, another forest
Pesquisa acadêmico-científica nas institui??es de ensino superior: do faz-de-conta à realidade do mundo digital
Amaral, Mirian Maia do;Nunes, Lina Cardoso;
Cadernos EBAPE.BR , 2009, DOI: 10.1590/S1679-39512009000100008
Abstract: the article presents some reflections about academic research procedures, taking into account the fact that the practices used in higher education institutions do not meet the demands of education and post-modernity. the proposal of the authors is the substitution of traditional practices for more efficient strategies of learning which favours dialogue, cooperation and interactivity among players of the educational process, starting from elementary education. the premise is that educational actors of this process should have the commitment to provide students the use of research tools and a complete access to the digital world. this education approach will be able to develop students' potentialities and improve the conditions for them to be the craftsman of their own knowledge.

Nikolaeva Kamila Sergeevna
Journal of Geoscience and Environment Protection (GEP) , 2015, DOI: 10.4236/gep.2015.32005
Abstract:

The paper deals with China’s involvement in the process of international environmental protection. The cooperation between China and international environmental organizations is analyzed. This article stresses on such issues as China’s cooperation with United Nations Environment Program, Asia-Pacific Economic Cooperation, Association of Southeast Asian Nations, China-Europe and China-Africa Cooperation. The key spheres of China’s activity in international environmental protection are examined in this paper. Thus, Chinese government attaches great importance to environmental protection and believes that environmental protection will have a direct impact on the overall situation of China’s modernization drive and its long-term development. While promoting economic growth, it has adopted a wide range of measures to strengthen environmental protection.

Probabilistic tools for assessment of pest resistance risk associated to insecticidal transgenic crops

Scientia Agricola , 2004, DOI: 10.1590/S0103-90162004000500003
Abstract: one of the main risks associated to transgenic crops expressing bacillus thuringiensis (bt) toxins is the evolution of pest resistance. the adoption of bt crops requires environmental risk assessment that includes resistance risk estimation, useful for definition of resistance management strategies aiming to delay resistance evolution. in this context, resistance risk is defined as the probability of the bt toxin resistance allele frequency (rfreq) exceeding a critical value (criticalfreq). mathematical simulation models have been used to estimate (rfreq) over pest generations. in 1998, caprio developed a deterministic simulation model with few parameters that can be used to obtain rfreq point estimates from point information about model parameters and decision variables involved in that process. in this work, the resistance risk was estimated using caprio′s model, by incorporating uncertainty to the resistance allele initial frequency (initialfreq). the main objective was to evaluate the influence of different probability distribution functions on the risk estimates. the simulation results showed that the influence of initialfreq input distributions on the risk estimates changes along pest generations. the risk estimates considering input normal distribution for initialfreq are similar to those ones obtained considering triangular distribution if their variances are equal. the use of uniform distribution instead the normal or triangular due to the lack of information about initialfreq leads to an overestimation of risk estimates for the initial generations and sub estimation for the generations after the one for which the critical frequency is achieved.

Abstract: One of the main risks associated to transgenic crops expressing Bacillus thuringiensis (Bt) toxins is the evolution of pest resistance. The adoption of Bt crops requires environmental risk assessment that includes resistance risk estimation, useful for definition of resistance management strategies aiming to delay resistance evolution. In this context, resistance risk is defined as the probability of the Bt toxin resistance allele frequency (RFreq) exceeding a critical value (CriticalFreq). Mathematical simulation models have been used to estimate (RFreq) over pest generations. In 1998, Caprio developed a deterministic simulation model with few parameters that can be used to obtain RFreq point estimates from point information about model parameters and decision variables involved in that process. In this work, the resistance risk was estimated using Caprio′s model, by incorporating uncertainty to the resistance allele initial frequency (InitialFreq). The main objective was to evaluate the influence of different probability distribution functions on the risk estimates. The simulation results showed that the influence of InitialFreq input distributions on the risk estimates changes along pest generations. The risk estimates considering input Normal distribution for InitialFreq are similar to those ones obtained considering Triangular distribution if their variances are equal. The use of Uniform distribution instead the Normal or Triangular due to the lack of information about InitialFreq leads to an overestimation of risk estimates for the initial generations and sub estimation for the generations after the one for which the critical frequency is achieved.

Abstract: the aim of this study was describe the relationship between grazing time and herbage intake and identify tools to grazing management of dairy cows grazing italian ryegrass (lolium multiflorum lam.) on a rotational grazing method. six dairy cows in mid-lactation period were allowed to graze paddocks during three grazing cycles. during each cycle cows grazed two paddocks with 9 days of occupation by paddock and an herbage allowance of 30kg dm cow-1 day-1. measurements were made in the last 9 days of each period and during intervals between cycles cows grazed an adjacent area with a mixed of temperate species. it was compared three grazing cycles and cows eating similar herbage amount with different daily grazing time. independently of herbage intake, daily grazing time increased 12min by cm of the reduction on leaf height. reductions on efficiency to graze are clearly associated to structural traits of canopy as proximity to ground level and stems + pseudo-stems content on the graze layer. in conclusion, under rotational grazing, daily grazing time is strongly associated with leaf height in the grazing layer, but it is not a good indicator of dm herbage intake. structural traits of canopy are clearly associated with efficiency to graze, independently of daily herbage intake.

Abstract: the aim of this research was to evaluate the effect of undegradable protein supplementation to dairy cows grazing italian ryegrass. twelve holstein cows in the mid lactation were used and treatments were 0 (zero) and a mixture (60:40) of ground corn + corn gluten meal (4.0kg cow day-1) evaluated along three periods of fifteen days. cows were distributed in four groups (two per treatment) and assigned to italian ryegrass plots submitted to intermittent grazing with a herbage allowance of 24kg of dm cow day-1. pre-grazing herbage mass (2325kg of dm ha-1) and sward surface height (15.8cm) were similar on plots and crude protein and ndf of ingested forage were 18.9 and 53,0%, respectively. supplementation did not affect herbage dm intake (mean=8.5kg cow day-1) but, both, total dm intake and metabolisable energy increased 3.0kg and 42mj cow day-1, respectively. supplementation increased milk production (4.0 kg.cow.day-1) but did not change protein and fat milk content (32.8 and 29.2g kg-1). at low herbage allowance, supplementation with corn ground meal (22% of crude protein) increase milk production on proportion of 1:1 and studies should be done at conditions of non- limitant herbage allowance.

La distanciation dans l’ uvre régionaliste de Grant Wood comme moyen de mise en échec du nationalisme “Tactics of Estrangement”: Distance and the Negation of Nationalism in Grant Wood’s Regionalist Paintings
Kamila Benayada
Revue LISA / LISA e-journal , 2009, DOI: 10.4000/lisa.273
Abstract: Regionalist painter Grant Wood’s works complied with much of the regionalist ideology as defined by critic Thomas Craven with its nationalism and its rejection of European Modernism. Wood displayed his concern for an American idiom in many of his works. However, while they use pictorial elements that suggest acceptance of the nationalist rhetoric of both Craven and the New Deal art projects, Wood’s works actually show aesthetic preoccupations similar to those of Modernists, and a growing distance from the mythic representations of America often found in regionalist art. While Wood empathises with his countrymen, he also introduces elements within the narrative, and aesthetic elements, that contradict his acceptance of the dominant discourse. Strange, inappropriate and unexpected incursions question the theme and aesthetic affiliation of a work. This deviation, this escape from the frame imposed by Craven and the New Deal, this estrangement, can work as a questioning of America, its values, its myths and its self-representation.
