Desenvolvimento de tijolos cerâmicos com escória de alto-forno

The construction industry is booming, and the federal government is heavily financially supporting public housing. This scenario is very favorable for the development of construction materials, especially low-cost construction. Thus, this study aims to develop a new class of unfired clay masonry bricks: GGBS stabilized bricks. Studies show that the ground granulated blast furnace slag, a material used as raw material in cement manufacture, can be used together with calcium oxide in soil stabilization for the manufacture of bricks. This study aims to test and identify the best parameters for the manufacture of unfired bricks, adapting its composition to the materials found in Brazil and identify the optimum curing conditions for our climate. So far preliminary studies were done to verify the technical feasibility of the material. Future studies should be done to ascertain the economic feasibility and environmental gains of such material

Mapeamento geológico-geontécnico de trecho da estrada vicinal na Serra de Itaqueri, Charqueada (SP)

Geological-geotechnical problems affecting escarps as well as embankment and fill slopes of roads and motorways may generate different types of unsteadiness, which are mainly arisen from the deficient knowledge about the physical environment. This results in unsuitable engineering projects and inadequate executions, which can be worsened by an occasional inappropriate maintenance of the construction. A geologically-geotechnically characterization of escarps and slopes is crucial in order to prevent these problems. This work deals with a geological-geotechnical study of 1:10.000 scale mapping in a stretch of a local road (CHQ-40) at the Serra de Itaqueri, Charqueada town, State of São Paulo. The stretch is known by several physical problems as erosion and mass movement. The methods of study were based on an integrative analysis of the diverse elements of the physical environment by using aerial photographs - to obtain the physiographic compartmentalization of terrain units - as well as field work - to accomplish the evaluation of the units by employing sketch lists. To achieve this, we selected several techniques in order to identify and classify different types of existing problems as erosion, landslide in embankments and fill slopes, rockfall, block rolling, among others. We also included the analysis of soil horizon, thickness and composition. The geological-geotechnical mapping resulted in six units: 1- Sandstones in cuesta’s backhill; 2 – Basalts in cuesta’s front; 3- Sandstones in cuesta’s front; 4 – Talus and colluvial deposits at cuesta’s foothill; 5- Sandstones of the Piramboia Formation in hillside; and 6 – Colluvial soil in the hill top. A characterization of the geological-geotechnical units is detailed, coupled to the cartographic material. Other cartographic products elaborated for this study included 1:10.000 maps of hypsometry, slope and curvature

Viabilidade do aproveitamento de resíduos de madeira para produção de móveis

The need to use waste from wood processing industry grows due to environmental demands imposed by laws, so like the need to introduce more competitive products in the market (it means better quality and acceptable cost) who must submit by the rational use of raw material, usually turning waste to sub products, what adds higher value for that. To this research, specific case from Ribon Company, located on Camaçari, Bahia-Brazil, has been studied. It is a treated wood producer. Bulk of monthly wood logs there is 70 m3. Its yield is 71,43%, where bulk of generated waste is monthly 20m3. As an exploitation way from generated waste, it has been suggested some options like: erosion protection to specific areas, a wildlife shelter as an henhouse etc, recreational articles, coal, linings, treadmills. However this research will give focus to the furniture design made of waste. As a conclusion, there is very much need to assign new utilizations to that sub used materials, since there is significant amount to increase company’s productive yield

O local de nidificação do sabiá-barranco (Turdus Leucomelas) (Aves, Turdidae) afeta a temperatura interna do ninho durante a incubação e cuidado à prole?

Individuals of the species Turdus leucomelas are adapted to live in environments already modified by humans, thus obtaining reproductive success in their nesting in vegetation, as well as built their nests in human buildings. Nests found in buildings are often less camouflaged, making them more exposed to predators compared to nests built in vegetation; however the nests built buildings are common, indicating a possible advantage associated with these nests. By means of this idea if was assumed that a possible advantage to this construction in buildings is linked to a change in variation in the internal temperature of the nest during incubation and development of pups until they leave their nests. Accordingly, with the aid of iButtons and TidBits (temperature data loggers), the present study aimed to analyze the influence of the nesting site on how the temperature is kept, and how it changes in the microenvironment in which the nest is inserted, indicating potential benefits associated with that choice. In the samples found with the vegetation, temperature data showed a pattern of temperature of the microenvironment of the nests is not very stable, varying with ambient temperature, whereas in the samples found with the human constructions, the temperature data showed a pattern of temperature microenvironment nests more stable for a long time. When comparing the two environments which they settled nests, as well as the different times of day (daytime and nighttime), how the temperature was kept and pattern of change within the nest was significantly different (F=43.85, p<0.001), with higher and more constant internal temperatures in nests installed in construction, compared to vegetation. When observing periods of the day, it was found that in both environments the temperature inside the nest reached higher values and higher than the environment at night, coinciding with the rest of the female at night. Data may suggest changes in the...

Análise de condicionantes geológico-geotécnicos para o rompimento de pequenas e médias barragens de terra: estudo de caso na bacia do rio Jaguari Mirim no município de São João da Boa Vista, SP

The act of containing water is one of the most practiced by the civilizations along history, in the will to increase the offer of water to many uses. The raise of environmental worries surround many human activities has given a big attention to dams. Indeed, the environmental consequences about dams are proporcional to their size, what gives to the big dams a more detailed Project and a bigger political concerning that increases the built, estability and maintenance of them. Then, the projects of medium and small dams are weak, limitaded to handbooks, textbooks and empirical recommendations, while the constructions of small dams are growing everytime more. With that being said, the present work intends to analise the geological and geotechnical conditionants that can cause break of small earth dams by making a case study in the Jaguari Mirim Watershed, located in the city of São João da Boa Vista (SP), and can be used to encourage the concern with small dams. In the area of study were identificaded, from satellite images, 248 dams. The map of physiographical compartmentalization defined by Pilachevsky (2013) was used to define the locations in the study área that would have bigger risk to the break of dams. Then, 9 of this dams were analised in field research, using references made by Cerri, Reis e Giordano (2011) and the risk of the analised dams were defined. A study about this type of structure is highly necessary to avoid big damages. An analysis of the geological and geotechnical conditionants that can cause break of dams guides the project in a way to avoid adverse consequences, especially when integrated with locacional conditions observed in the place of the dam’s building

Estratégias de relativização nas variedades lusófonas

This paper, which examines restrictive and non-restrictive constructions in the Lusophone varieties, assumes that Portuguese has a set of relativization strategies that are recognized by typological linguistics as constructions that define related groups of languages. Thus, it is possible that these different strategies, when employed by the same linguistic system, not really constitute variants of the same syntactic variable but the speaker’s actual choices facing the necessity to perform different social and discursive functions.

Percurso diacrônico de completivas introduzidas por 'como' no português

As a more extensive issue, this paper deals with the polysemy attested in all Romance languages between interrogative pronouns and subordination markers in complex sentences. It investigates, specifically, the behavior of objective complement clauses introduced by “como” (“how”) in constructions in which they occur as equivalent to the meaning of prototypical declarative complement clause introduced by the conjunction “que” (“that”). It analyzes complement clauses introduced by “como” and “que” occurring in representative Portuguese texts from the thirteenth to the twentieth centuries. The results of the comparative analysis between the two forms of clausal complement show that in archaic Portuguese “como” was used primarily to introduce complement clauses of factive verbs. When the complement clause is introduced by “como”, the content that is presupposed as true due to the meaning of matrix verb has reinforced this factuality. In the passage from the archaic to the modern period, there was a drastic decrease in the frequency of occurrences of complement clauses with “como”, which are replaced by the form of completive introduced by the conjunction “que” in the context of factual constructions. In contemporary Portuguese, this replacement is fully established. Complement clauses with “como” remain rare and limited to specific contexts in which “como” maintains its reinforcement function of factual meaning.

Distinções entre modalidade deôntica objetiva e subjetiva no português falado: o caso do verbo 'dever'

The modal distinctions proposed by Hengeveld (2004), reexamined by Hengeveld and Mackenzie (2008) within the Functional Discourse Grammar (FDG), consider the existence of five types of modality: facultative, deontic, volitive, epistemic and evidential. Taking into special account the deontic modality, there are evidences that it can be subdivided into objective and subjective, as analyzed by Olbertz and Gasparini-Bastos (2013) in auxiliary constructions of spoken Spanish. This wok aims to investigate the contextual elements that favor the interpretation of these two values when they are expressed by the modal auxiliary verb “dever” (must) in spoken Portuguese data.

Junção em mudança: reanálise morfossintática e redes polissêmicas de 'que nem'

Neste trabalho, analiso aspectos da constituição e do uso do juntor que nem, em dados da modalidade de enunciação falada do português. A questão maior é mostrar que a inserção de que nem no paradigma dos juntores, por meio de processos de gramaticalização, resulta em quatro novos padrões funcionais, que refletem uma rede de parentesco semântico no domínio das relações modais. As construções com que nem são descritas a partir do pareamento entre forma e significado, com o propósito de defender que arquiteturas sintáticas diferenciadas contribuem para a interpretação da polifuncionalidade semântica de que nem; e que as fontes sincrônicas do português ajudam a desvendar etapas do processo de reanálise de que e nem, tendo em vista as tendências diacrônicas sobre mudança de juntores nas línguas (Kortmann, 1997).
