The microstructures of four commercial linear low density polyethylenes (LLDPE) were evaluated and correlated with their sealing properties. Atomic Force Microscopy (AFM), Temperature Rising Elution Fractionation (TREF), Differential Scanning Calorimetry (DSC) and Crystallization Analysis Fractionation (CRYSTAF) experiments revealed that the comonomer distribution is one of the main factors that influence the sealing properties. The superior sealing performance showed by metallocene LLDPE samples in ...

Abstract Blends of isotactic polypropylene (PP), ethylene‐propylene rubber copolymer (EPR), and ethylene‐propylene crystalline copolymer (EPC) can be produced through in situ polymerization processes directly in the reactor and blends with different structure and composition can be obtained. In this work we studied the structure of five reactor‐made blends of PP, EPR, and EPC produced by a Ziegler‐Natta catalyst system. The composition of EPR was related to the ratio between ethylene and propylene ...

This paper analyses the possibility of using altered aggregates and Reclaimed Asphalt Pavement (RAP) in cold mix asphalt used to produce grouted macadam pavements in comparison with the conventional hot mix porous asphalt skeleton. It also investigates the cementitious grouts performance when incorporated with milled glass and Panasqueira Waste Mud and geopolymerics grouts. This paper aims mainly at studying the introduction of mineral waste materials in grouted macadam pavements. The results indicate ...

The environmental issues raised over recent years, mainly the lowering of fuel consumption and the consequent emission of polluting gases, have led to a bigger concern with the environment. As a response to such concern, the asphalt road industry has developed warm mix asphalts. These are part of a set of new technologies that are being developed in order to reduce both the energy consumption and the gas emissions into the atmosphere, by lowering the mixing temperature. On the other hand, the incorporation ...

The asphalt industry has been under pressure to reduce its emissions. This can be achieved, from one hand, by decreasing the mixing and laying temperatures of asphalt mixtures. On the other hand, recycling of Reclaimed Asphalt Pavement (RAP) is a viable solution that allows reducing waste production and resources consumption. This paper presents a study that combines Warm Mix Asphalt with the use of RAP aggregates. These mixtures, while being produced at lower temperature than traditional Hot Mixtures ...

Dengue is the most important arboviral disease worldwide. Dengue diagnosis is usually made by serology, but serological techniques do not identify the infecting strain, and are only useful late in the course of infection. Several reverse transcription-polymerase chain reaction (RT-PCR) protocols have been described for dengue diagnosis but none of them has been used on a regular basis. We conducted a validation study of PCR-based diagnosis in an area (in Brazil) where dengue-1 virus has been circulating ...

We evaluate the RT3DE DIs in a population with normal electrocardiograms and 2- and 3-dimensional echocardiographic analyses. This information is relevant for cardiac resynchronization therapy.We evaluated 131 healthy volunteers (73 were male, aged 46 +/- 14 years) who were referred for routine echocardiography; who presented normal cardiac structure on ...

Abstract The introduction of epoxy groups in the polymer backbone is one of the most promising methods of modifying polydienes. In this work the performance of the classical catalytic system VO(acac) 2 / tert -butylhydroperoxide was evaluated for the epoxidation of polydienes. The polymers investigated were a hydroxylated poly(butadiene), two polybutadienes with high and with low 1,4-content, a poly(isoprene), and a styrene–butadiene copolymer. The epoxidized polymers were characterized by IR, 1 H ...

The porous asphalt (PA) use in road pavements surface layers is one of the most common solutions worldwide to address the climate changes impact like heavy rain. The aim of this study is to evaluate the performance of these mixtures with the cellulosic fibres addition, known for their adherence capacity between the aggregates and the binder. These will help to prevent the binder loss by drainage, which is one of the main problems of porous asphalt, since the fine aggregates content is reduced. Comparing ...

Nowadays, the increasing urbanisation and the effect of climate change in cities has been a constant concern. In particular, the floods cause a significant increase in surface runoff, mostly on roads and parking areas. As an alternative to asphalt pavements, usually used in these areas, permeable pavements have been developed with Porous Asphalt (PA). These pavements allow the infiltration of water from the surface to the ground due to the high void content of the PA, thus reducing the surface runoff ...

Road pavements need a deep characterization of the surface layer, with which the vehicles have direct contact and, therefore, must provide security to the users. The use of permeable asphalt pavements (PAP) with porous layers has provide obvious advantages in reducing runoff and the rainwater infiltration into the soil or for storage. However, the study of the interaction between the pavement surface layer and the tire rubber requires additional tests in terms of texture and friction, since they ...

Two unusual pyridine alkaloids, 7′-multijuguinone (1) and 12′-hydroxy-7′-multijuguinone (2), were isolated from the leaves of Senna multijuga, together with the known flavonoid rutin. The structures of the new alkaloids were established on the basis of spectroscopic data interpretation. Compounds 1 and 2 exhibited moderate in vitro acetylcholinesterase (AChE) inhibitory activity, in comparison with the standard compound physostigmine.

A high incidence of irregularities occurred in all populations, especially irregular chromosome segregation, abnormal spindles, chromosome transfer among microsporocytes, and sticky chromosomes. These irregularities may be attributed in part to the large number of chromosomes detected in these populations (2n=54) suggesting hexaploidy, a phenomenon detected here for the first time in this ...
