Detection limit

the smallest circumbinary planet detected to this date, the inner planet, Kepler-47 b still has a radius of 3.0±0.1 Earth radii. In addition, too small to be measured directly, has been determined to have a 3-α upper limit of 2 Jupiter masses. This determination is based on non-detection of timing variations of stellar orbit. As the mass of planet is not known which means its density also remains undetermined. This in return means that it’s not…

ABSTRACT Objective: The purpose of the study is to compare and evaluation of the diagnostic efficiency of Toluidine Blue, Lugol’s iodine and Acetic acid in the detection of potentially malignant disorders (PMD’S). Materials and methods: The study population consisted of 30 patients with clinically suspicious PMD’S. The lesions were stained consecutively with toluidine blue, lugol’s iodine & acetic acid depending on the retention of the dyes, the biopsy site was determined and sent for…

ELISA (Enzyme-Linked Immunosorbent Assay) ELISA is a technique to detect and quantify substances like proteins, antibodies, and hormones. The target antigen is immobilized to the bottom of the well and then an antigen-specific detection antibody is added. The detection antibody makes it possible to measure results. The three most common formats of ELISA would be direct assay, indirect assay, and sandwich assay. In direct assay, the antigen immobilizes to the bottom of the well where a labeled…

Saxagliptin. The method was carried out on reverse- phase C18 inertsil column, with mixture of Methanol: Water ( 80:20) ratio as a mobile phase, 1 ml / min flow rate. Different analytical parameters such as linearity, precision, accuracy, Limit of detection (LOD), Limit of Quantification (LOQ), robustness were determined according to the International conference on Harmonization ICH guidelines. The regression analysis for the linearity data analysis for the linear data analysis shows a good…

beginning of the infection, in some patients may not still develop specific antibodies to hepatitis B ("OBI primary") or because of the clearance of specific antibody to hepatitis B in the end stage of chronic hepatitis B. The possibility of the non-detection of HBsAg in serum of HBV-infected individuals may be due to surface gene escape mutants or mutation in the polymerase gene. Therefore, anyone can be a carrier of OBI. In addition, there are cases that are called as “False” OBI. They may…

Non parametric tests It is a hypothesis test which does not need population distribution. For instance there are numerous hypothesis tests which depend upon assumptions that population must be normally distributed along with the parameters. Main advantages of non- parametric tests are that they do not rely on assumptions, so they can be easily used where population is non-normal. One thing to be kept in mind, that these tests may have few assumptions related to the data. They might not be…

It utilizes carrier phase shifting and synchronous detection to permit two DSB signals to occupy the same frequency band. The two DSB signals are orthogonal to each other. IV. NOISE AND CHANNELS IN COMMUNICATION SYSTEMS A. Noise in Communication Systems The term noise refers to unwanted electrical signals that are always present in electrical systems. The presence of noise superimposed on a signal tends to obscure or mask the signal; limits the receiver’s ability to mask correct symbol…

One major program that was directly developed as a result of this act was called the National Breast and Cervical Cancer Early Detection Program. The program 's inception was developed with federal funding appropriated by the public act (Centers for Disease Control [CDC], 2015a). The program served as the first federally mandated breast cancer prevention program for low- income…

synthesized and used for the nonenzymatic electrochemical detection of hydrogen peroxide (H2O2). The PpPD layer also helps the MWCNTs to be dispersed in the water together with the PB formation and fixing on the surface of the MWCNTs. Moreover, PpPD, a conductive polymer, increases the electronic conductivity and stability of MWCNTs. By combining the selectivity and catalytic capacity of PB for H2O2, a synergistic effect was observed for the H2O2 detection. The morphology and chemical…

Introduction Chronic kidney disease (CKD) is a common condition in cats, known to affect 1 in 3 cats during their lifetime, and resulting in the persistent loss of kidney function over time. The disease is silent in its early stages, incurable, and ultimately results in death. An excessive level of phosphorus in commercial cat food is likely contributing to the prevalence and severity of CKD in cats. The feeding of lower phosphorus foods would benefit the entire cat population. A Primer on…
