Based on existence of the chromite deposits in the Sistan and Baluchestan province in Iran, and also various applications of chromite in different industries, it is expected that the establishment of chromite processing plant is required in the erelong. The geographical location of a processing plant can have a strong influence on the success of an industrial venture. The processing plant site ...

The theoretical performance of some flammable refrigerants, namely, propane (HC290), butane (HC600), isobutane (HC600a), cyclopropane (HCC270), HFC152a and HCFC142b have been comparativelyassessed as alternatives to CFC12. Th~s has been done for a range of evaporating temperatures by using some standard refrigera~ion parameters like pressure ratio, ·specific compressor displacement, theoretical...

Developers of assistive technology products need to ensure that their offerings meet the requirements of end users, and that usability issues have been discovered prior to manufacture. This may be difficult for SMEs (Small Medium Enterprises) who may lack the necessary skills and resources required to plan and conduct an evaluation. To assist SMEs in the assistive technology market, a stand alo...

Noninvasive prenatal testing (NIPT) is becoming increasingly popular with some offering it as a primary screen option in all patients in place of serum screening. Serum screening offers insight into placental function, which NIPT does not. Abnormal levels of analytes in the serum screen have been associated with pregnancy complications.

Decisions on chemical substitution are made rapidly and by many stakeholders; these decisions may have a direct impact on consumer exposures, and, when a hazard exists, to consumer risks. Flame retardants (FRs) represent particular challenges, including very high production volumes, designed-in persistence, and often direct consumer exposure. Newer FR products, as with other industrial chemical...

Chronic liver diseases (CLD) are common and may lead to fibrosis, cirrhosis, and hepatic malignancy. Detection and staging of liver fibrosis is crucial for management of patients with CLD. At present, liver biopsy is the standard method for staging fibrosis, but biopsies are poorly tolerated because they are invasive and associated with some discomfort and complications. In addition, limitation...

The classical chi-square test of goodness-of-fit compares the hypothesis that data arise from some parametric family of distributions, against the nonparametric alternative that they arise from some other distribution. However, the chi-square test requires continuous data to be grouped into arbitrary categories. Furthermore, as the test is based upon an approximation, it can only be used if the...
