greatly reduced the amount of the sample solution and the measuring time.1-3 However, the electronic osmometers reported to date are in use of flaccid mem branes which result in baseline instability and limit the use to low con centrations of colloid solute in solutions. Recently, we have designed an electronic osmometer with a rigid semiperme able membrane made from a baked clay disc permeated...

This article presents the method of extraction-preconcentration of Lead, Cadmium, and Nickel ions from food samples using the Ghezeljeh montmorillonite nanoclay (Geleh-Sar-Shoor) as a new native adsorbent in batch single component systems. The extraction-preconcentration of heavy metals were carried out by applying the solid phase extraction (SPE) method followed by atomic abs...

Indium (In) is commonly hosted in Sn-rich deposits but rarely reported in Sn-poor deposits. However, an In-rich and Sn-poor skarn deposit, the Qibaoshan Cu-Zn-Pb deposit, has been identified in south China. Geochemical analyses were undertaken on 23 samples representing the following mineral assemblages: sphalerite-pyrite, pyrite-chalcopyrite, pyrite-sphalerite-galena-chalcopyrite, pyrite, magn...

Overview: The objectives of the Earth-Mars Cave Detection Project is to identify regions on Mars likely to contain caves and/or cave-bearing geology through (1) the analysis of multispectral imagery from past and current orbital missions and other orbital assets (e.g., radar), and (2) the investigation of terrestrial analogs for the identification of associated thermal, and geosignatures. The p...

Image analysis is an image processing technique that aims to extract features or information from images. Image analysis in medicine has a special place because is a basis for disease diagnosis for physicians. Electrophoresis is a laboratory separating technique. Electrophoresis images are created during the electrophoresis process. Serum protein and hemoglobin electrophoresis test are the ...

purpose – this paper aims to describe the role of public libraries in bridging the digital divide. the paper firstly reviews the existing literature body in this area and then suggests a number of practical solutions. digital divide is a concept which appears in the area of information and communication technology (ict) since 1990 and refers to the existing inequality in accessing to ict among ...

Generally, there are multiple sensor suites on existing rover platforms such as NASA's Sample Return Rover (SRR) and the Field Integrated Design and Operations (FIDO) rover at JPL. Traditionally, these sensor suites have been used in isolation for such tasks as planetary surface traversal. For example, although distant obstacle information is known from the narrow FOV navigation camera (NAVCAM)...
