Measurements of true polymer melt temperature in a circular cross-sectional duct by moving temperature sensor [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2002 The objective of this research was to design and develop an experimental apparatus and a temperature sensor in order to measure true melt temperature rise due to the shear heating during the flow.

Revisiting internal gravity waves analysis using GPS RO density profiles: comparison with temperature profiles and application for wave field stability study [PDF]
Atmospheric Measurement Techniques, 2018 We revise selected findings regarding the utilization of Global Positioning System radio occultation (GPS RO) density profiles for the analysis of internal gravity waves (IGW), introduced by Sacha et al. (2014).

Journal of the Atmospheric Sciences, 1966 Abstract An equation for the daytime lapse rate of temperature as a function of z/L is derived assuming the lapse rate varies as z−⅔ in very light winds. This variation is presumed to result from the geometry of buoyant plumes. The equation, which agrees very well with some data taken by Dyer, predicts a maximum value for the lapse rate at a fixed ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

FEBS Letters, EarlyView.This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Meteorologische Zeitschrift, 1999 Some additional remarks are given to Hoinka’s paper concerning especially the first stratospheric temperature profiles obtained from sounding balloons since 1894, but misinterpreted by the contemporary authorities for some years.

Tropospheric profiles of wet refractivity and humidity from the combination of remote sensing data sets and measurements on the ground [PDF]
Atmospheric Measurement Techniques, 2013 We reconstruct atmospheric wet refractivity profiles for the western part of Switzerland with a least-squares collocation approach from data sets of (a) zenith path delays that are a byproduct of the GPS (global positioning system ...

Measuring Cluster Temperature Profiles with XMM/EPIC [PDF]
, 2000 Using the PV observation of A1795, we illustrate the capability of XMM-EPIC to measure cluster temperature profiles, a key ingredient for the determination of cluster mass profiles through the equation of hydrostatic equilibrium. We develop a methodology

Aggressive prostate cancer is associated with pericyte dysfunction
Molecular Oncology, EarlyView.Tumor‐produced TGF‐β drives pericyte dysfunction in prostate cancer. This dysfunction is characterized by downregulation of some canonical pericyte markers (i.e., DES, CSPG4, and ACTA2) while maintaining the expression of others (i.e., PDGFRB, NOTCH3, and RGS5).
