Analytical Study of Lanolin as Potential Biomarker of Prehistoric Sheep‐Shearing Practice

open access: yesChemistry–Methods, EarlyView.
Lanolin, a complex wax found on sheep wool, accumulates on shearing tools, such as flint and obsidian blades, used since the Neolithic. This study explores lanolin's degradation patterns as a potential biomarker for prehistoric sheep‐shearing practices, employing micro‐Fourier transformed infrared spectroscopy, hyperspectral imaging, and gas ...

Critical powder loading and the rheology of nanosized cemented carbide with titanium carbide as grain growth inhibitor for injection molding [PDF]

open access: yes, 2018
The purpose of this paper is to determine the critical powder loading of WC-Co and to study the effect of TiC powder on the rheological behavior of MIM feedstock. WC-TiC-6Co metal powder was taken as raw material. 60% (mass fraction) palm stearin and 40%

Pharmacokinetics and Bioequivalence of a Novel Extended‐Release Formulation of Methylphenidate Hydrochloride for Attention‐Deficit/Hyperactivity Disorder

open access: yesClinical Pharmacology in Drug Development, EarlyView.
Abstract Extended‐release (ER) formulations of the stimulant methylphenidate are commonly used to treat attention‐deficit/hyperactivity disorder in both children and adults. Previous studies have shown that the clinical effectiveness of long‐acting methylphenidate formulations is closely tied to the drug's pharmacokinetic (PK) profile, highlighting the

High-pressure grinding rolls: model validation and function parameters dependency on process conditions

open access: yesJournal of Materials Research and Technology, 2019
A model for High Pressure Grinding Rolls (HPGR) was developed in this work based on the widely used Population Balance Model (PBM). This approach uses a variety of different functions one of which is the breakage distribution function. The methodology to

Development of Water‐Dispersible CuS Nanoparticles for Chemo–Photothermal Therapy and Photoacoustic Application

open access: yesChemPhysChem, EarlyView.
Water‐dispersible CuS nanoparticles are developed by the soft chemical approach using phosphorylethanolamine as a surface passivation agent for chemo–photothermal therapy and photoacoustic application. Photothermal therapy (PTT) is a promising treatment option for cancer. However, biocompatibility, water dispersibility, and good photoresponsiveness are

The importance of the PLE (Personal Learning Environment)

open access: yesAvances en Supervisión Educativa, 2013
Learning should be a continuous process in our lives. This means that we must take into account the non-formal and informal learning, as they allow us developing the learning process throughout life. To achieve this, we have to find spaces that encourage

Understanding the Dissolution Kinetics of a DINCH Plasticized PVC: Experimental Design and Applied Modeling

open access: yesChemSusChem, EarlyView.
Experimental design and applied modeling of the dissolution kinetics of poly(vinyl chloride) containing di‐isononyl‐1,2‐cyclohexaandicarboxylaat (DINCH) plasticizer, with varying temperature (T), plastic particle size (dp), and solvents. Polymer dissolution‐precipitation recycling is a promising pathway to increase plastic recycling rates.
