Acid rain is a major problem for animals, plants, buildings, and also the top glass of photovoltaic (PV) solar panels greenhouses. Air pollutants such as NOx, NH3, H2S can mix with water in atmosphere to form acid rain. It was discovered that atmospheric vapor adsorbed on surface lead corrosion surface. The purpose this work obtain protective film glasses used different domains cells, windows, ...

Abstract This work presents the first results of iconographic study and analytical characterisation a set four stained-glass panels that are part collection National Palace Pena (Sintra, Portugal). These were collected by King Ferdinand II in mid-nineteenth century, for his main residence Necessidades (Lisbon, Portugal), only presented to general public 2011. contributes with knowledge Technica...

The neuropathologic diagnosis of brain tumors entails the microscopic examination of conventional formalin-fixed paraffin-embedded tissue samples surgically removed from a radiographically defined lesion. A preliminary diagnosis is often rendered with frozen sections, though the final or definitive diagnosis usually requires more elaborate studies. Typically, the tissue is first fixed for a min...

The diagnosis of uterine smooth muscle neoplasms by light microscopy is difficult. Multiple classification schemes have been proposed based on mitotic rate, nuclear atypia, and the presence or absence of necrosis. None of these classification systems has been entirely successful. This study was undertaken to evaluate the use of selected immunohistochemical and histochemical markers in different...

Morphological observations of paraffin-embedded histological sections stained with H&E led to the discovery of some cytoplasmic changes which occur in different conditions, although they look alike under the light microscope. These hepatocytic changes consisted basically of homogeneous areas which are weakly eosinophilic in H&E-stained sections. They are frequently referred to as "inclusion" bo...

Interpretation of the protected specimen brush (PSB) technique is based on quantitative bacterial cultures (QC), which unfortunately requires at least 24 h. We prospectively compared the diagnostic value of direct examination (DE) and QC of PSB specimens in 75 patients with suspected pneumonia. We also determined the optimal technique for DE. QC was performed using the serial dilution technique...

An antiserum against human epidermal keratins was used to detect keratins in frozen sections of various rabbit and human tissues by indirect immunofluorescence. Strong staining was observed in all stratified squamous epithelia (epidermis, cornea, conjunctiva, tongue, esophagus, vagina, and anus), in epidermal appendages (hair follicle, sebaceous gland, ductal and myoepithelial cells of sweat gl...

This paper describes two applications of the tandem scanning reflected-light microscope (TSM) for the observation of the structure of individual cells growing in tissue culture. First, the TSM is used as an alternative to interference reflection microscopy (IRM) or total internal reflection aqueous fluorescence microscopy (TIRAF) to observe cell-substratum adhesions in unstained living cells gr...
