In this study, a functional colorant, Berberine, extracted from Berberis vulgaris wood was applied onto wool fiber using the extract of roots of Rumex Hymenosepolus as biomordant. The effect of treatment variables on the color strength of dyed fibers was examined. The fastness properties of dyed wool against washing, light, dry and wet rubbing were evaluated. Dyed samples were tested for an...

• Polluted indoor air can lead to discomfort, reduced efficiency and even ill health amongst employees and residents in modern buildings. • Wool carpet has been shown to rapidly neutralize formaldehyde, nitrogen dioxide and sulphur dioxide, common contaminants in today's indoor environment. • Not only does wool neutralize these contaminants more quickly and completely than synthetic carpet fibe...

Staple strength (SS) and coefficient of variation of fibre diameter (FDCV) were measured on full length staples from 12 months of wool growth, and wool staples cut to 80 or 60 % of their full length from the tip. The results show that SS and FDCV for the different staple length treatments are heritable but lower for staples 60% or shorter than their full length. SS and FDCV measured on wool sta...

This study applied Computational Fluid Dynamics (CFD) to determine the effects of windinduced convection through mineral wool in a ventilated rainscreen system. Wind studies of a conceptual low-rise building subject to a wind speed of 6.7 m/s demonstrated dynamic airflows and rainscreen velocities ranging from 0.1 to over 3 m/s. Localized pressure fields near cladding support framing increased ...

Squamous cell carcinoma of the skin is the second most common cutaneous malignancy. Despite various available treatment methods and advances in noninvasive diagnostic techniques, the incidence of metastatic cutaneous squamous cell carcinoma is rising. Deficiency in effective preventive or treatment methods of transformed keratinocytes leads to necessity of searching for new anticancer agents. T...

Temporary polygyny (the presence of multiple queens) occurs in honeybee colonies when virgin queens (VQs) are reared for reproductive swarming or queen replacement. During these events, workers perform vibration signals on queen cells and emerged queens, and these signals may influence which VQ becomes the new laying queen of a colony. We examined the role of vibration signals during queen comp...

Gregory of Nyssa lauded his older sister Macrina as "the common glory of our family" and acclaimed her as "the great Macrina" who had achieved the highest summit of human virtue. Indeed, in two works, the Life of Macrina and The Dialogue on the Soul and the Resurrection, he portrayed her as the ideal Christian teacher and philosopher, seeking God with her whole heart and mind.' In these two wor...

In this paper, a flame retardant dimethyl-2-(methacryloyloxyethyl) phosphate (DMMEP) was applied to wool fabrics by the graft copolymerization technique initiated with potassium persulfate (KPS) in water media. FTIR and SEM testing were used to explore the grafting evidence on the fiber surface, the SEM results show chemical deposition on the wool fiber surface and the scales could not be seen ...
