The penetration rates of 10 hydrophobic solvents through the excised abdominal rat skin were quantitatively determined by using the in vitro method reported previously. The hydrophobic solvents studied were benzene, toluene, ethylbenzene, o-xylene, styrene, n-pentane, 2-methylpentane, n-hexane, n-heptane and n-octane. There was a great diversity in the ability of the hydrophobic solvents to pen...

The Bitcoin Market Potential Index conceptualizes and ranks the potential utility of bitcoin across 178 countries to show which countries have the greatest potential to see bitcoin adoption. The index utilizes a data set with 40 variables related to bitcoin’s current core functions: store of value, medium of exchange, and technology platform. The variables are grouped into the index’s seven equ...

for a determination of soil characteristics one should have access to instruments that can measure these characteristics, including: soil penetration resistance with high accuracy. one of the accurate instruments commonly employed in soil penetration determinations is cone penetrometer. this apparatus, by measuring soil cone index at different soil depths can provide useful about information ab...

A specific rock energy profile can be generated for every hole, and thus a drilling site can be mapped for this index. A special data acquisition system was devel...

The main goal of this paper is to study statistical indices and evaluate AGC indices in power system which has large penetration of the WTGs. Increasing penetration of wind turbine generations, needs to study more about impacts of it on power system frequency control. Frequency control is changed with unbalancing real-time system generation and load . Also wind turbine generations have more flu...

Radioactive microspheres could offer several advantages over gases in the investigation of pulmonary ventilation. Monodisperse microspheres of human serum albumin have been produced using a spinning-disc generator, and kits were prepared for subsequent labelling with technetium-99m. The average labeling efficiency was 88% and unlabeled Tc-99m was removed before aerosol delivery. A simple system...

BACKGROUND Most myocardial infarctions are caused by the rupture of small rather than large plaques in the arteries of the heart that are beyond the detection limit of current technologies. METHODS AND RESULTS Recently, optical coherence tomography (OCT) has demonstrated considerable potential as a method for high-resolution assessment of vulnerable plaque. However, intravascular OCT imaging ...

Owing to the limited source of human skin (HS) and the ethical restrictions of using animals in experiments, in vitro skin equivalents are a possible alternative for conducting particle penetration experiments. The conditions for conducting penetration experiments with model particles, 15-nm gold nanoparticles (AuNP), through nonsealed skin equivalents are described for the first time. These co...

The move to the cloud brings a number of new security challenges, but the application remains your last line of defense. Engineers are extremely well poised to perform tasks critical for securing the application—provided that certain key obstacles are overcome. Cloud Shifts the Burden of Security to Development
