Política curricular no Estado de São Paulo nos anos 1980 e 1990

Este texto apresenta um estudo sobre a política curricular implementada no Estado de São Paulo nas décadas de 1980 e 1990 para as primeiras séries do ensino fundamental. Examina o currículo prescrito cotejando-o com os contextos práticos de desenvolvimento do currículo. A pesquisa revela que a política curricular desse período articulou-se fortemente com a produção acadêmica em educação. Ressalta ainda a continuidade na política de produção de materiais de orientação curricular nos últimos 20 anos, buscando difundir e tornar hegemônico um pensamento pedagógico inovador. Também verifica que esses materiais circularam de diferentes formas na rede de ensino e foram apropriados de maneira seletiva pelos professores que adotaram, sobretudo, as indicações práticas.

Iowa Pore Index Test, MLR-80-2, 1980

The objective of the investigation was the development of a test that would readily identify the potential of an aggregate to cause D-cracking because of its susceptivity to critical saturation. A Press-Ur-Meter was modified by replacing the air chamber with a one-inch diameter plastic tube calibrated in milli-. It was concluded that the pore index was sufficiently reliable to determine the D-cracking potential of limestone aggregates in all but a few cases where marginal results were obtained. Consistently poor or good results were always in agreement with established service records or concrete durability testing. In those instances where marginal results are obtained, the results of concrete durability testing should be considered when making the final determination of the D-cracking susceptibility of the aggregate in question. The following applications for the pore index test have been recommended for consideration: concrete durability testing be discontinued in the evaluation process of new aggregate sources with pore index results between 0-20 (Class 2 durability) and over 35 (Class 1) durability; composite aggregates with intermediate pore index results of 20-35 be tested on each stone type to facilitate the possible removal of low durability stone from the production process; and additional investigation should be made to evaluate the possibility of using the test to monitor and upgrade the acceptance of aggregate from sources associated with D-cracking.

Quebra de dormência de sementes do feijão-mungo

No laboratório de sementes da Universidade Federal de Santa Catarina, Florianópolis, SC, avaliou-se o efeito de tratamentos pré-germinativos sobre a quebra de dormência em sementes do feijão-mungo (Vigna radiata L., Leguminosae). As sementes de quatro cultivares (Pusa 9173, ML 267, NM 51 e Chun Nam 4) foram submetidas aos tratamentos com água quente (80°C), álcool à temperatura ambiente e ácido sulfúrico concentrado. Os tratamentos com ácido sulfúrico concentrado foram os que apresentaram as maiores porcentagens de germinação. Os tratamentos com imersão em álcool durante 5 e 10 minutos, e em água à temperatura de 80°C por 5 e 10 minutos mostraram-se eficientes, atingindo percentuais de germinação superiores aos da testemunha. No tratamento de imersão em água à temperatura de 80°C por 15 minutos, verificou-se acentuada mortalidade de sementes, reduzindo drasticamente o percentual de germinação. O tratamento com ácido sulfúrico concentrado, por 6 minutos, possibilitou uma porcentagem de germinação de 96%, sendo assim o mais indicado. As cultivares Pusa 9173, ML 267 e NM 51 apresentaram maior intensidade de dormência em comparação à cultivar Chun Nam 4.

Eficiência de diferentes volumes e concentrações de calda para quebra de dormência na macieira cultivar 'Gala'

Este trabalho teve como objetivo avaliar a eficiência dos diferentes volumes de calda --340, 450, 1.000, 1.350 L/ha -- em duas concentrações de óleo mineral (OM) + cianamida hidrogenada (CH) -- 30+3 e 50+5 L/ha, respectivamente -- em macieira da cultivar Gala. Os resultados mostraram que nos anos com, pelo menos, 800 unidades de frio, todos os volumes e concentrações foram eficientes, exceto o de 340 L/ha, na concentração de 30+3 L/ha de OM+CH. Nos anos com menos de 800 unidades de frio, os melhores resultados foram com a concentração de 50+5 L/ha de OM+CH, em todos os volumes testados.

Iowa Motorcycle Ride Meter, HR-1019, 1980

The Iowa Department of Transportation (Iowa DOT) through the Highway Division is responsible for the design, construction and maintenance of roadways that will provide a high level of serviceability to the motorist. First, the motorist expects to be able to get where he wants to go, but now he also demands a minimum level of comfort. In the construction of new roadways, the public is quick to express dissatisfaction with rough pavements. The Highway Division of the Iowa DOT (formerly Iowa State Highway Commission) has a specification which requires a "smooth-riding surface". For over 40 years, new portland cement concrete (pcc) pavement has been checked with a 10-foot rolling straightedge. The contractor is required to grind, saw or mill off all high spots that deviate more than 1/8" from the 10-foot straight line. Unfortunately, there are instances where a roadway that will meet the above criteria does not provide a "smooth-riding surface". The roadway may have monger undulations (swales) that result in an undesirable ride. The objective of this project was to develop a repeatable, reliable time stable, lightweight test unit to measure the riding quality of pcc pavement at normal highway speed the day after construction.

High Range Water Reducer in Portland Cement Concrete Made with D-Cracking Susceptible Coarse Aggregate, HR-1021, 1980

The objective of this research was to determine of the use of High Range Water Reducers (HRWR) (resulting in a lower water content ratio) with a D-cracking susceptible crushed limestone coarse aggregate would yield significant improvement in the durability.

Evaluation of Fly Ash in Portland Cement Concrete Pavement in Monona County, Iowa, HR-200, 1980

The primary objectives of this research project were: 1. Determine and recommend solutions for problems relating to shipping, storing and batching of fly ash. 2. Establish a procedure for batching, mixing and placing uniform concrete with specified air content and consistency. 3. Demonstrate that concrete of comparable quality can be produced.
