The ability to accurately evaluate hydrokinetic turbine concepts at small-scale in experimental facilities is important for the development of new devices. Problems introduced by working at lab-scale include operation in a transitional Reynolds number regime and cross-sectional blockage. These factors are shown to influence performance characteristics of a helical cross-flow turbine tested over...

Metal–organic polyhedra (MOPs) are intrinsically porous cage-like structures; however, they frequently display low porosity due to their agglomeration caused by solvent exchange and removal, which results in the blockage of pore windows. This study presents unprecedented single-crystal-to-single-crystal transformation a cuboctahedral MOP-OH ([Cu24L24], H2L = 5-hydroxybenzene-1,3-dicarboxylic ac...

four patients were studied for intercostals nerve blockade in cholecystectomy. all of the patients were poor risks (class 4) and received premedication before the procedure. intercostals nerve blockade (icnb) of the 7th and 10th thoracic nerves on the right side was performed with lidocaine 1% plus adrenaline 5 ml. at each segment, t7-t10 (a total dose of 20 ml). ventilation was controlled usin...

A PCR-free, optics-free device is used for the detection of Escherichia coli (E. coli) 16S rRNA at 10 fM, which corresponds to ~100-1000 colony forming units/mL (CFU/mL) depending on cellular rRNA levels. The development of a rapid, sensitive, and cost-effective nucleic acid detection platform is sought for the detection of pathogenic microbes in food, water and body fluids. Since 16S rRNA sequ...

We investigate the totally asymmetric exclusion process on Z, with the jump rate at site i given by ri = 1 for i 6= 0, r0 = r. It is easy to see that the maximal stationary current j(r) is nondecreasing in r and that j(r) = 1/4 for r ≥ 1; it is a long outstanding problem to determine whether or not the critical value rc of r such that j(r) = 1/4 for r > rc is strictly less than 1. Here we prese...

The requirement to boost the resolution of nanopore-based biosequencing devices necessitates integration novel biosensing techniques with reduced sensitivity background noise. In this article, we probe signatures translocating polymers in magnetic fields induced by ionic currents through membrane nanopores. Within framework a previously introduced charge transport theory, evaluate field signals...

Whether a state of nasal hyperresponsiveness influences antigen-induced biphasic nasal blockage and sneezing were examined using a guinea pig model of allergic rhinitis. Sensitized animals were challenged with an antigen, Japanese cedar pollen, once every week. Before the 13th challenge, the animals were randomly divided into 2 groups, and then the 13th challenge was performed (Groups A-0 and B...

We analyze the performance of a free-space optical (FSO) link affected by atmospheric turbulence and line-of-sight (LOS) blockage. For this purpose, the atmospheric turbulence induced fading is modeled by the ℳ distribution, which includes the Gamma-Gamma distribution as special case. We exploit the fact that the physical interpretation of the ℳ distribution allows to split the optical energy t...

Abstract The assessment of visual blockages in cross-drainage hydraulic structures, such as culverts and bridges, is crucial for ensuring their efficient functioning preventing flash flooding incidents. extraction blockage-related information through computer vision algorithms can provide valuable insights into the blockage. However, absence comprehensive datasets has posed a significant challe...
