Identification of positive staining is often qualitative and subjective. This is particularly troublesome in pigmented melanoma lesions, because melanin is difficult to distinguish from the brown stain resulting from immunohistochemistry (IHC) using horse radish peroxidase developed with 3,3'-Diaminobenzidine (HRP-DAB). We sought to identify and quantify positive staining, particularly in melan...

A simple, rapid and sensitive spectrophotometric method has been developed for the determination of trace amounts of copper in tap water, polluted water, human hair and alloys. The proposed method is based on the reaction of copper with potassium iodide in acidic medium to liberate iodine, which bleaches violet color of azure B and the absorbance is measured at 644nm. This decrease in absorbanc...

A facile spectrophotometric method is proposed for determination of Colchicoside (COLSID) in bulk and in dosage forms using ceric ammonium sulphate (CAS). Method involves addition of a known excess of CAS to COLSID and determination of residual CAS with a fixed amount of either Azure B (AB), measuring absorbance at 633nm or Safranin O (SO), measuring absorbance at 519 nm. Calibration graphs are...

Thank you for downloading programming windows azure programming the microsoft cloud. Maybe you have knowledge that, people have search hundreds times for their chosen books like this programming windows azure programming the microsoft cloud, but end up in malicious downloads. Rather than enjoying a good book with a cup of tea in the afternoon, instead they are facing with some infectious virus ...

Different methods have been adopted for the removal and degradation of dyes from effluents of textile, dyeing and printing industries. These methods have their own merits and drawbacks. In the present investigation, Lead sulfide has been used as a photocatalyst for the degradation of azure-B. The effect of different parameters like the pH, concentration of dye, amount of semiconductor and light...

Hybrid cloud environments are a highly scalable and cost-effective option for enterprises that need to expand their on-premises infrastructure. In every hybrid cloud solutions, the issue of inter-cloud network connectivity has to be overcome to allow communications, possibly secure, between resources scattered over multiple networks. Network visualization provides the right method for addressin...

Data market is an emerging type of cloud service that enables a data owner to sell their data sets in a public cloud. Buyers who are interested in a certain dataset can access the data in the market via a RESTful API. Accessing data in the data market may not be free. For example, it costs USD 12 per month to obtain 100 “transactions” from the WorldWide Historical Weather dataset in Windows Azu...

Cloud computing is emerging as a promising platform for compute and data intensive scientific applications. Thanks to the on-demand elastic provisioning capabilities, cloud computing has instigated curiosity among researchers from a wide range of disciplines. However, even though many vendors have rolled out their commercial cloud infrastructures, the service offerings are usually only best-eff...
