Effect of metakaolin and alccofine in high strength concrete

High strength concrete is defined as concrete with characteristic cube strength above 40 MPa. The applications of high strength concrete are bridges, aqueducts, dams, high rise buildings etc. This work involves the comparative study of various mineral admixtures such as alccofine and metakaolin on high strength concrete. Alccofine is a new generation micro fine concrete material which is beneficial with respect to workability as well as strength. The desirable properties of Metakaolin make it mostly preferred additives in high strength concrete. In this study, cement is partially replaced with alccofine, metakaolin at 5, 10 and15%. The mechanical properties like compressive strength, flexural strength and split tensile strength are evaluated and compared. The strength properties are maximum for the concrete mix with alccofine

A note on parallel and pipeline computation of fast unitary transforms

The parallel and pipeline organization of fast unitary transform algorithms such as the Fast Fourier Transform are discussed. The efficiency is pointed out of a combined parallel-pipeline processor of a transform such as the Haar transform in which 2 to the n minus 1 power hardware butterflies generate a transform of order 2 to the n power every computation cycle

L’innovation pédagogique vue de l’intérieure

Cet article vise à souligner l’importance de l’ethnographie de l’éducation comme outil pour comprendre et décrire de manière critique les pratiques pédagogiques innovatrices qui ne prennent du sens que lorsqu’elles sont envisagées à partir de l’intérieur, c’est-à-dire du point de vue de leurs praticiens. D’autre part, elle fait le compte-rendu de l’extension de cette méthode d’analyse de l’école, à travers les programmes de Master et de Doctorat de Sciences de l’Education, dans la spécialité d’Innovation Pédagogique de l’Université de Madère et son Centre de Recherche en Education (CIE-UMa), qui se déroulent à Madère, à Santarém (près de Lisbonne) et au Brésil (dans les villes de Brasília, São Luis do Maranhão, Salvador, Ibicaraí, Feira de Santana, Recife et Fortaleza) et qui intègrent une bonne partie de la pensée ethnographique de Lapassade, parmi d’ autres auteurs. Finalement, la communication témoigne de notre hommage en forme d’action à la contribution scientifique de Georges Lapassade

This study examines and answer the problems regarding the suitability of matter of illegal mining effort by presenting mining expert at the trial of the District Court Pacitan with provisions KUHAP. As for further study on mining expert evidence in illegal mining case examination considered by District Court Judge Pacitan.This research includes the doctrinal law study or prescriptive normative. Legal materials collection techniques in this study is the literature study, conducted by reading and studying the contents of primary legal materials and secondary legal materials from literature study to collect and collate the law writing relating to the study problem. Legal materials that have been collected and analyzed by case approach. Based on this type research, then the analysis techniques of legal materials used the deduction method syllogism to formulate legal facts by making conclusion on major and minor premise. Based on the study results can be concluded that the prosecutor in the case of attesting his illegal mining business in the expert on trial in state court pacitan has been in accordance with the provisions of the expert KUHAP mining expert testimony in the case investigation is considered illegal mining by Pacitan District Court Judge, District Court Judge consideration Pacitan in assessing the expert testimony in the case investigation of illegal mining is the expert testimony has a the strength of evidence free or virj bewijskracht

Populational fluctuation and spatial distribution of Alphitobius diaperinus (Panzer) (Coleoptera; Tenebrionidae) in a poultry house, Cascavel, Parana state, Brazil.

Abstract Knowledge of the population fluctuation and spatial distribution of pests is fundamental for establishing an appropriate control method. The population fluctuation and spatial distribution of the Alphitobius diaperinus in a poultry house in Cascavel, in the state of Parana, Brazil, was studied between October, 2001 and October 2002. Larvae and adults of the lesser mealworm were sampled weekly using Arends tube traps (n = 22) for six consecutive flock grow-outs. The temperature of the litter and of the poultry house was measured at the same locations of the tube traps. Beetle numbers increased continuously throughout all the sampling dates (average 5,137 in the first week and 18,494 insects on the sixth week). Significantly greater numbers of larvae were collected than adults (1 to 20 times in 95% of the sampling points). There was no correlation between temperature and the number of larvae and adults collected, therefore no fluctuation was observed during the sampling period. The population growth was correlated to litter re-use. The highest temperatures were observed in deep litter. The spatial distribution of larvae and adults in the poultry house was heterogeneous during the whole period of evaluation. Results suggest that monitoring in poultry houses is necessary prior to adopting and evaluating control measures due to the great variability of the insect distribution in the poultry house.
