Cortical and whole kidney radionuclide transit parameters were studied in 16 patients who underwent a pyeloplasty for unilateral pelviureteral junction (PUJ) obstruction. As expected, the whole kidney mean transit time was found to be very sensitive but, due to the low specificity, not very helpful in the distinction between obstructed and nonobstructed kidneys. The cortical transit reflected, in some cases, the favorable surgical outcome. In other cases, however, it could not be considered as a reliable parameter of the clinical status, since it was found to be normal preoperatively and prolonged postoperatively in patients whose parenchymal function improved significantly after surgery and who had their clinical symptoms relieved.

Topology is being widely adopted to understand and to categorize quantum matter in modern physics. The nexus of topology orders, which engenders distinct quantum phases with benefits to both fundamental research and practical applications for future quantum devices, can be driven by topological phase transition through modulating intrinsic or extrinsic ordering parameters. The conjoined topology, however, is still elusive in experiments due to the lack of suitable material platforms.

High-pressure and high-temperature Raman spectra of natural pyromorphite, vanadinite and mimetite were measured up to 11 GPa and 973 K, respectively. No phase transition was observed within the temperature and pressure ranges in this study. Raman modes for pyromorphite, vanadinite and mimetite vary with temperature or pressure linearly.

A comprehensive study was conducted on the life history parameters of an important vector Culicoides oxystoma Kieffer (Diptera: Ceratopogonidae), to standardize potential rearing procedures. Data on life history traits and rearing conditions are crucial for establishing laboratory colony and conducting vector competence-based studies utilizing specimens with a known rearing history. Six different substrate compositions were used to rear the larvae: S1: habitat mud containing cattle manure + nutrient broth + yeast, S2: yeast, S3: habitat mud containing cattle manure + nutrient broth, S4: nutrient broth, S5: sterile (habitat mud consisting cattle manure + nutrient broth + yeast) and S6: tap water.

In this work, a theoretical approach is developed to investigate the structural properties of ionic microgels induced by a circularly polarized (CP) electric field. Following a similar study on chain formation in the presence of linearly polarized fields [T. Colla , , 2018, , 4321-4337], we propose an effective potential between microgels which incorporates the field-induced interactions a static, time averaged polarizing charge at the particle surface.
