In the Saltpeter Works Humberstone and Santa Laura, declared World Heritage Site in 2005, an unusual deterioration process of the wood takes place in which individual fibers can be observed on the surface of the wood. This paper gives a description and assessment of the damage observed in the installations belonging to both office buildings. Also, ...
The aluminum poses a versatility of uses in modern life. The possibility of deterioration of pitting them is one of the main considerations for the manufacturer, in order to avoid claims. In this sense ASTM G100-89 proposes a method of assessment of aluminum by means of the evaluation of potential versus applying cyclic galvanic polarizations affor...

The use of urine reagent strips, coupled with questions pertaining to water contact patterns, might be considered for point-of-contact diagnosis of S. haematobium where microscopy is unavailable.
Dye chemistry facilitated important advances in several scientific areas, as is the case of histology. In this field dyes are used to record images of biological tissues and cell anatomy under the light microscope. Besides that, the related science of Histochemistry addresses the understanding of the chemical composition and reaction mechanisms tak...

The processes of modelling and reconstruction of holograms are based on the calculation of the diffraction integral either on its kirchhoff-fresnel or rayleight-sommerfeld formulation. Numerically, such an integral can be evaluated via different approaches: the convolution theorem, angular spectrum, and fresnel transform, among others. In this pape...
Sequences of LSU and SSU ribosomal RNA genes and phylogeny have not been widely investigated for the dinoflagellate Coolia monotis Meunier, and no information is available on the small and large rDNA subunits of Mediterranean strains. A strain isolated from the Thermaikos Gulf in northern Greece was identified as C. monotis—a new record for the Gre...
Electron microscopic examination of thin section from rice hoja blanca virus (RHBV)-infected barnyard [Echinocloa colonum (L.) Link] revealed the occurrence of large masses of flexuous, tubular particles, 8-10 nm wide, both in the cytoplasm and nucleus. These inclusions were absent in cells from healthy plants. This observation is consistent with p...
