Talc‐Tempered Pottery From Bala Hissar, Kabul: An Analytical Study

open access: yesArchaeometry, EarlyView.
ABSTRACT Potsherds of cooking ware excavated at Bala Hissar archaeological site in Kabul were studied using X‐ray fluorescence (XRF), scanning electron microscope‐energy dispersive X‐ray spectrometry (SEM‐EDS), Raman spectroscopy, X‐ray powder diffraction (XRPD), thermogravimetric analysis (TGA) and optical microscopy.

Deindustrialization and demographic change: Evidence from big plant closures and downsizing

open access: yesCanadian Journal of Economics/Revue canadienne d'économique, EarlyView.
Abstract We estimate the causal effect of big manufacturing plant closures and downsizing on the socioeconomic composition of Canadian cities between 2001 and 2021. Our instrumental variables estimates show that big manufacturing plant closures and downsizing—large local labour demand shocks—lead to less population growth and a shift in the demographic

Stabilizing effect of epoxidized sunflower oil as a secondary stabilizer for Ca/Hg stabilized PVC

open access: yeseXPRESS Polymer Letters, 2008
Unsaturated triglyceride oil sunflower was epoxidized and characterized by chemical and spectroscopic methods. Epoxidized sunflower oil (ESO) was used as an organic thermal co-stabilizer for rigid poly(vinyl chloride) (PVC) in the presence of tricalcium ...

Enhancing the fastness characteristics of weld‐dyed cotton and recycled nylon 6,6 fabrics via sodium alginate and titanium dioxide

open access: yesColoration Technology, EarlyView.
Abstract This study investigates a sustainable dyeing and finishing strategy for recycled nylon 6,6 and organic cotton fabrics dyed with weld. Following meta‐mordant dyeing using alum under Natural Organic Dye Standard (NODS)‐compliant conditions, the fabrics were subjected to functional finishing with titanium dioxide as a multifunctional ...

Investigation into the dyeing of pre‐mordanted & cationised woven cotton fabric with cochineal

open access: yesColoration Technology, EarlyView.
Abstract Dyeing cotton with natural dyes typically requires the pre‐application of a mordant, which enables better dye exhaustion from solution and ‘fixes’ the colorant in the fibre. The most common application system for cellulosic fibres is a combination of plant‐derived tannins and aluminium salts, such as aluminium sulphate.

Comparative evaluation of reactive dye structures on colour strength enhancement in caustic‐treated regenerated bamboo fabrics

open access: yesColoration Technology, EarlyView.
Abstract Regenerated bamboo fibres offer a sustainable alternative to conventional cellulosic materials; however, achieving high and reproducible colour strength with reactive dyes may depend on both fibre accessibility and dye molecular architecture.

Bayesian regularization optimization technique for hybrid nanofluid with Cattaneo Christov flux model using wax and sand nanoparticles

open access: yesDiscover Nano
The current study employs Bayesian-regularization optimizer technique with artificial neural networks (BROT-ANNs) to investigate the significance of local thermal non-equilibrium influences on wax + sand-based hybrid nanofluid flow across a disk with the

Reactive Red 195‐loaded halloysite for cotton dyeing and printing: Adsorption, characterisation and comparison with conventional exhaustion dyeing

open access: yesColoration Technology, EarlyView.
Abstract Textile wet processing generates dye‐containing effluents that require effective recovery and valorisation strategies. Halloysite nanoclay was used to capture Reactive Red 195 from a model aqueous solution, and the resulting dye‐loaded solid (REDHA7) was subsequently applied once to cotton by exhaustion dyeing and pigment‐type printing ...

Success and failure in England's patent system: New evidence from patent applications, 1783–1834

open access: yesThe Economic History Review, EarlyView.
Abstract Our understanding of the relationship between the English patent system and technical change during the industrial revolution is based entirely on the study of successful patents. We address this feature by providing the first study of unsuccessful patent applications in England during the first industrial revolution.

‘Elbow grease and yellow soap’: Housework time in working‐class households in late‐nineteenth and early twentieth‐century Britain

open access: yesThe Economic History Review, EarlyView.
Abstract Housework is central to feminist calls for recognition of women's work, economic histories explaining the sexual division of labour, and claims regarding the progressive role of scientific knowledge. Yet little is known about the time it actually took. We address this lacuna.
