In this work, we have investigated the possibility of using COOH functionalized CdTe quantum dots (QDs) as fluorescent nanosensor for detection some environmentally hazardous metal ions (Cr3+, Pb2+, Cu2+, Zn2+ and Co2+) in aqueous phase. COOH–CdTe QDs are prepared medium characterized by UV–visible, photo luminescence FTIR spectrometry. Optical response is observed to be time temperature depend...

Biological experiments based on organ-on-chips (OOCs) exploit light Time-Lapse Microscopy (TLM) for a direct observation of cell movement that is an observable signature underlying biological processes. A high spatial resolution essential to capture dynamics and interactions from recorded by TLM. Unfortunately, due physical cost limitations, acquiring videos not always possible. To overcome the...

• Work of our department and of others has shown that the magnitude of coronary flow (CF) is determined primarily by the oxygen consumption of the heart (OoC)" in such a manner that oxygen availability alters in a parallel fashion with O2C while oxygen extraction (O2E), within limits, remains constant." Two kinds of factors cause deviation of this relationship : (A) Factors which independently ...

BACKGROUND Total hip arthroplasty (THA) is a common last-resort treatment for hip disease, but postoperative patients often complain of discrepancies in leg length. This study introduces a device designed to increase the precision of the femoral neck osteotomy and reduce the incidence of leg length discrepancy. METHODS Forty-eight patients undergoing THA were divided into two groups, with and...

The dicarboxylate radical -OOC--CH--CH(OH)COO- was generated in an N2O-saturated fumarate solution by high energy ionizing radiation. When NADH was present in the solution, product analysis indicated a stoichiometry of 2 molecules of the radical reacted with 1 NADH molecule to form 2 malate and 1 enzymatically active NAD+ molecules. In a similar experiment using tritium label on position A of N...

Perfect (v,K, 1) difference families ((v,K, 1)-PDF in short, and (v, k, 1)-PDF when K = {k}) were introduced by Ge et al. for their useful application to the construction of properly centered permutations, which can be used to construct new radar arrays. Some works had been done on the existences of (v, k, 1)-PDFs, while little is known when |K| ≥ 2 except for partial results by Ge et al. In 19...

[1] Submicron organic aerosol was measured simultaneously with an Aerodyne aerosol mass spectrometer (AMS) and a particle-into-liquid sampler (PILS) capable of measuring water-soluble organic carbon (WSOC) during the winter and summer of 2004 in Tokyo. Both techniques are being used to investigate the formation of secondary organic aerosol (SOA), and the combined data sets provide unique insigh...

Elements of arbitrariness in the standard setting process are explored, and an alternative to the use of cut scores is presented. The first part of the paper analyzes the use of cut scores in large-scale assessments, discussing three different functions: (1) cut scores define the qualifications used in assessments; (2) they simplify the reporting of achievement distributions; and (3) they allow...

Few realize that for large matrices dense matrix computations achieve nearly the same performance when the matrices are stored on disk as when they are stored in a very large main memory. Similarly, few realize that, given the right programming abstractions, coding Out-of-Core (OOC) implementations of dense linear algebra operations (where data resides on disk and has to be explicitly moved in ...
