background: to compare the effectiveness of 3 commercial gel bait formulations containing fipronil (goliath ã cockroach gel 0.05% ai), chlorpyrifos-a (clean bait ã gel, 2% ai), and chloropyrifos-b (serpa ã gel 2% ai) against german cockroaches ( blattella germanica ) when stored at 23°c and 30° c after treatment. methods: laboratory bioassays consisted of placing groups of fifteen cockroaches ...
BACKGROUND Manual counting of microvessels is subjective and may lead to unacceptable interobserver variability, which may explain conflicting results. AIMS To develop and test an automated method for microvessel counting and objective selection of the hot spot, based on image processing of whole sections, and to compare this with manual selection of a hot spot and counting of microvessels. ...
Thermal insulation materials extend the shelf life of food and reduce energy consumption. Polyurethane (PU) are often used to keep hot cold. Improving thermal properties PU can significantly contribute savings lower food-related costs in pharmaceutical industries. Polyurethane/expanded graphite (PU/EG) composites were obtained by hot-pressing adding expanded (EG) foams. Composites with 0.05%, 5...
BACKGROUND Studies have examined the effects of temperature on mortality in a single city, country, or region. However, less evidence is available on the variation in the associations between temperature and mortality in multiple countries, analyzed simultaneously. METHODS We obtained daily data on temperature and mortality in 306 communities from 12 countries/regions (Australia, Brazil, Thai...
Cervical cancer tends to occur at an early age. Treatment for cervical cancer includes surgery, chemotherapy, radiotherapy or their combination. The 2-year survival of early cervical cancer after surgery or chemoradiothearpy reaches over 80%. Stage Ib2 cervical cancer, however, is a high-risk early stage cervical cancer with easy recurrence and metastasis. Its 5-year survival is as low as about...
Background and Objective: Glumerular diseases are among the most prevalent causes of renal chronic insufficiencies. This study aimed to analyze the prevalence of various kinds of glumerulonephritis based on the findings of electron microscope. Materials and Methods: This study had a descriptive retrospective and cross sectional strategy. Slides of patients (124 cases) who had undergone kidn...
In this paper, we propose a method to compare and visualize spectrograms in a low dimensional space using manifold learning. This approach is divided in two steps: a data processing and dimensionality reduction stage and a feature extraction and a visualization stage. The procedure is applied on different types of data from a hot rolling process, with the aim to detect chatter. Results obtained...
An electron microprobe is an electron microscope designed for the non-destructive x-ray microanalysis and imaging of solid materials. It is essentially a hybrid instrument combining the capabilities of both the scanning electron microscope (SEM) and an x-ray fluorescence spectrometer (XRF), with the added features of fine-spot focusing (~ 1 micrometer), optical microscope imaging, and precision...
