REDACS: Regional emergency-driven adaptive cluster sampling for effective COVID-19 management.

As COVID-19 is spreading, national agencies need to monitor and track several metrics. Since we do not have perfect testing programs on the hand, one needs to develop an advanced sampling strategies for prevalence study, control and management. Here we introduce REDACS: Regional emergency-driven adaptive cluster sampling for effective COVID-19 management and control and justify its usage for COVID-19.

Solvent Evaporation Rate as a Tool for Tuning the Performance of a Solid Polymer Electrolyte Gas Sensor.

Solid polymer electrolytes show their potential to partially replace conventional electrolytes in electrochemical devices. The solvent evaporation rate represents one of many options for modifying the electrode-electrolyte interface by affecting the structural and electrical properties of polymer electrolytes used in batteries. This paper evaluates the effect of solvent evaporation during the preparation of solid polymer electrolytes on the overall performance of an amperometric gas sensor.

Investigation of Calcium Forms in Lichens from Travertine Sites.

Lichens are symbiotic organisms with an extraordinary capability to colonise areas of extreme climate and heavily contaminated sites, such as metal-rich habitats. Lichens have developed several mechanisms to overcome the toxicity of metals, including the ability to bind metal cations to extracellular sites of symbiotic partners and to subsequently form oxalates. Calcium is an essential alkaline earth element that is important in various cell processes.

Surface Analyses of PVDF/NMP/[EMIM][TFSI] Solid Polymer Electrolyte.

Thermal treatment conditions of solid polymer polymer electrolyte (SPE) were studied with respect to their impact on the surface morphology, phase composition and chemical composition of an imidazolium ionic-liquid-based SPE, namely PVDF/NMP/[EMIM][TFSI] electrolyte. These investigations were done using scanning electron microscopy, Raman spectroscopy, Fourier transform infrared spectroscopy, differential scanning calorimetry as well as X-ray photoelectron spectroscopy and time-of-flight secondary ion mass spectroscopy. A thoroughly mixed blend of polymer matrix, ionic liquid and solvent was deposited on a ceramic substrate and was kept at a certain temperature for a specific time in order to achieve varying crystallinity.

The effect of thermal treatment on ac/dc conductivity and current fluctuations of PVDF/NMP/[EMIM][TFSI] solid polymer electrolyte.

The experimental study deals with the investigation of the effect of diverse crystallinity of imidazolium ionic-liquid-based SPE on conductivity and current fluctuations. The experimental study was carried out on samples consisting of [EMIM][TFSI] as ionic liquid, PVDF as a polymer matrix and NMP as a solvent. After the deposition, the particular sample was kept at an appropriate temperature for a specific time in order to achieve different crystalline forms of the polymer in the solvent, since the solvent evaporation rate controls crystallization.

Reversal of Vecuronium-induced Neuromuscular Blockade with Low-dose Sugammadex at Train-of-four Count of Four: A Randomized Controlled Trial.

Background: Rocuronium-induced neuromuscular block that spontaneously recovered to a train-of-four count of four can be reversed with sugammadex 0.5 or 1.0 mg/kg.

[Oculocardiac reflex in ocular surgery. Some means of prevention from consequences (author's transl)].

In 80 patients undergoing surgery for retinal detachment, cardiac rhythm was observed to improve some means of prevention from consequences of oculocardiac reflex. The injection of a parasympatholytic agent shown its effectiveness; heavy morphinic analgesia prevented from cardiac disturbances induced by scleral cryoapplication; retrobulbar block had no effect.

[Familial immune deficit and genetic deficiency of adenosine deaminase or of nucleoside phosphorylase (author's transl)].

Two familial enzymopathies, always related to the combined immune deficit, are reviewed. Both are clinically characterized by repeated infections since the birth, leading to fatal issue before age of 4 years. The hereditary deficiency of adenosine deaminase is associated to the deficient functions of T and B lymphocytes.

[Hereditary deficiency in the enzymes of the biosynthesis of collagen. The Ehlers-Danlos syndromes (author's transl)].

The mechanism of the biosynthetic pathway of collagen is briefly summarised. The hereditary enzyme deficiencies of this pathway concern some of the Ehlers-Danlos syndromes. Seven clinically well defined varieties of these syndromes have been recognized, all presenting, as common feature, an hyperextensivitry of joints and hyperelastic, excessively fragile skin.
