An Innovative Approach to Exploit the Reflection Spectroscopy of Liquid Characteristics.

Reflection spectroscopy, in the visible-near-infrared-shortwave infrared region (Vis-NIR-SWIR, 350-2500 nm), is a useful technology to extract chemical and physical properties of materials, but might be useless in identifying the spectral features of transparent or dark opaque liquids. Low reflectance values of a liquid reduce the ability to identify characteristic absorption features at specific wavelengths in the reflectance spectrum. In this study, we present a rapid and easy-to-use method to increase the measured reflectance spectrum and expose characteristic absorption features of a liquid.

Spatiotemporal estimation of air temperature patterns at the street level using high resolution satellite imagery.

Although meteorological monitoring stations provide accurate measurements of Air Temperature (AT), their spatial coverage within a given region is limited and thus is often insufficient for exposure and epidemiological studies. In many applications, satellite imagery measures energy flux, which is spatially continuous, and calculates Brightness Temperature (BT) that used as an input parameter. Although both quantities (AT-BT) are physically related, the correlation between them is not straightforward, and varies daily due to parameters such as meteorological conditions, surface moisture, land use, satellite-surface geometry and others.

Spatio-temporal behavior of brightness temperature in Tel-Aviv and its application to air temperature monitoring.

This study applies remote sensing technology to assess and examine the spatial and temporal Brightness Temperature (BT) profile in the city of Tel-Aviv, Israel over the last 30 years using Landsat imagery. The location of warmest and coldest zones are constant over the studied period. Distinct diurnal and temporal BT behavior divide the city into four different segments.

Occupational asthma due to piperazine citrate.

Background: Piperazine is a secondary heterocyclic amine that may give rise to occupational asthma of uncertain mechanism.

Methods: We report on a 42-year-old woman, a process operator in a chemical factory, who developed work-related symptoms of rhinitis and asthma upon exposure to piperazine citrate. She remained symptom free during holidays and days off work.

Is Anisakis simplex responsible for chronic urticaria?

The association of chronic urticaria (CU) to parasitic infestations has been poorly studied. Recently, sensitization to the parasite larva Anisakis simplex has been described as the cause of acute urticaria and anaphylaxis. The aim of this work was to study the relationship between sensitization to A.

Piroxicam-induced photodermatitis. Cross-reactivity among oxicams. A case report.

Background: there is a group of patients with contact allergy to thimerosal (thiosalicylic acid and ethylmercuric chloride), thiosalicylic acid sensitized, who develop photodermatitis to piroxicam. We present a case which we have investigated cross-reactivity among different oxicams.

Methods And Results: a 44-year-old man with contact allergy to thimerosal.
