Discuntindo as concepções de professores do segundo ano do ensino fundamental sobre transtorno de déficit de atenção e hiperatividade (TDAH)

Researches show high rates of school failure on the part of students who are unable to learn, referring to them as the idea of an incapable individual and intended not to achieve the goals proposed during the school year. Among the most varied problems posed by teachers and that are instilled in students in order to justify the poor performance of the same, we find Disorder Attention Deficit Hyperactivity Disorder (ADHD). Faced with this problem the objective was to investigate teachers‟ conception of the second year of primary education on ADHD, knowing well the mechanisms of identification, confirmation and referral of these cases, as well as the appropriate treatment and teaching practices suggested. To achieve the proposed objective a literature search was performed supplemented by an empirical study in which we used two instruments to collect data: interviews and observation. The study included empirical two teachers from a state school and two teachers from a private school, all of a midsize city in São Paulo. The interviews showed that teachers of second grade of elementary school consider ADHD a neurological problem in order to be addressed, however, chose not to speak about the treatment carried out by drugs. The observations revealed that the discourse of these teachers are away from their practices, it is worth noting that the differences in these two situations studied - state and private network - are so disparate and interfere in this important teaching practice

Gestão de resíduos sólidos domiciliares orgânicos: práticas e técnicas para a destinação final na cidade de Rio Claro - SP

The present work is the analysis of the practices and techniques currently used in the final allocation given to organic household solid waste in the city of Rio Claro - SP. As the major part of Rio Claro’s household solid waste is formed by the organic fraction, as well as in the rest of the country, this research proposes a study on what is done with that portion of the waste, its treatment and where finally destined, based on the National Solid Waste Politic, recently approved in 2010. With the use of this organic part, for example: as animal feed supplement or compost embodiment for the purpose of producing organic fertilizer, enables the decrease of the percentage of the total destined to dumps and landfills. This total percentage has already been reduced after the popularization of the beneficial recycling programs in Brazil, which are still growing. As cities and the purchasing power of its individuals grow, there is also a consequent growth of waste production by society. The household whether domestic solid waste are lower than Industrial Solid ( RSI ) waste for the production in million tons ( Mton ) quantities , however, those residues are more visible on a daily basis - in cities and periphery as well, due to the inadequate management, - and also offer , as well as industrial and agricultural wastes , several types of harmful effects to the population when managed incorrectly. Therefore, the research aims to assist in the study of Solid Waste Management (MSW) for efficient Urban and Environmental Planning in a midsize city. Thus, this project aims to analyze in the city of Rio Claro, how the allocation of these materials is done and whether these practices denote effective improvement regarding the proper management of waste, in the same way that the recycling chain would allow this effect

Residential planning, driver mobility and CO2 emission

The literature on residences and citizens’ transports has focused on either reforming traffic managing in response to residential relocation or post-evaluation of urban planning policies or the evolution of the urban spatial form. In a city there are hotspots that attract the citizens and most of the transportation in the city arises as the citizens’ movement between their residence and the hotspots. Little scholarly attention has been devoted to the possibility to minimize citizens’ transportation in the city by the urban planning of residential areas. In this paper we propose a method to evaluate the environmental impact (in terms of CO2-emissions) of urban plans of residential areas. The method is illustrated in a Swedish case of a midsize city which is presently preoccupied with urban planning of new residential areas in response to substantial population growth due to immigration. The residential plans aims to increase the compactness and residential density in the current center and sub centers leads to less CO2 emissions compare to urban expansion to the edge of the city. The plans of concentrated apartment buildings are more effective in meeting residential needs and mitigating CO2 emissions than dispersed single-family houses.

Raman microscopic study of the Li amphibole holmquistite, from the Martin Marietta Quarry, Bessemer City, NC, USA

The Raman spectrum of holmquistite, a Li-containing orthorhombic amphibole from Bessemer City, USA has been measured. The OH-stretching region is characterized by bands at 3661, 3646, 3634 and 3614 cm–1 assigned to 3 Mg–OH, 2 Mg + Fe2+–OH, Mg + 2Fe2+–OH and 3 Fe2+–OH, respectively. These Mg and Fe2+ cations are located at the M1 and M3 sites and have a Fe2+/(Fe2+ + Mg) ratio of 0.35. The 960–1110 cm–1 region represents the antisymmetric Si–O–Si and O–Si–O stretching vibrations. For holmquistite, strong bands are observed around 1022 and 1085 cm–1 with a shoulder at 1127 cm–1 and minor bands at 1045 and 1102 cm–1. In the region 650–800 cm–1 bands are observed at 679, 753 and 791 cm–1 with a minor band around 694 cm–1 attributed to the symmetrical Si–O–Si and Si–O vibrations. The region below 625 cm–1 is characterized by 14 vibrations related to the deformation modes of the silicate double chain and vibrations involving Mg, Fe, Al and Li in the various M sites. The 502 cm–1 band is a Li–O deformation mode while the 456, 551 and 565 cm–1 bands are Al–O deformation modes.
