In the present work an evaluation was carried out on the effect dye-bath pH and mordant type on the obtained shades and fastness properties in wool dyeing with cochineal. In this way wool samples were first mordanted with four different mordants and subsequently dyed with cochineal at different levels of dye-bath pH. Colorimetric evaluations were carried out and fastness properties of the dyed ...

In addition to evidence supporting serotonergic modulation of respiratory rhythmogenesis, serotonergic mechanisms play a role in central respiratory chemoreception. We examined the role of serotonin 5HT1A receptors in respiratory rhythmicity and central respiratory chemosensitivity in in vitro brainstem preparations of the bullfrog tadpole, Rana catesbeiana. Spontaneous respiratory motor output...

Low viscosity (<100 cSt) silicon oil droplets are placed on a high viscosity (1000 cSt) oil bath that vibrates vertically. The viscosity difference ensures that the droplet is more deformed than the bath interface. Droplets bounce periodically on the bath when the acceleration of its sinusoidal motion is larger than a threshold value. The threshold is minimum for a particular frequency of excit...

We developed an experimental model to study the permeability of individual retinal vessels in vitro using microperfusion techniques adapted from kidney tubule studies. The retinal vessels were isolated by freehand dissection and mounted on a microperfusion apparatus. When inulin was perfused luminally, it was diluted to 80.2 +/- 2.3% of its initial concentration. However, no radioactive leak in...

PURPOSE We aimed to evaluate the efficacy of warm water sitz baths in patients who have undergone transurethral resection of the prostate (TURP) owing to lower urinary tract symptoms secondary to benign prostatic hyperplasia. MATERIALS AND METHODS We reviewed the records of 1,783 patients who had undergone TURP between 2001 and 2009. In the warm water sitz bath group, patients were instructed...

results anxiety scores in the intervention groups in active phase after intervention were significantly lower than the control group (p < 0.001). anxiety scores before and after intervention in intervention groups in transitional phase was significantly lower than the control group (p < 0.001). patients and methods this clinical trial study was performed after obtaining informed written consent...

one of the well-known herbal drugs is henna (lawsonia inermis). according to the components in henna, several beneficial properties (i.e., antimicrobial, anti-inflammation, wound healing, trypsin inhibitory and antioxidant) have been reported. the present study was designed to investigate the effects of two natural substances (sodium chloride and henna extract) on experimental skin lesion due t...

A Maxwell’s demon type “information engine” that extracts work from a bath is constructed from a microscopic Hamiltonian for the whole system including a subsystem, a thermal bath, and a nonequilibrium bath of phonons or photons that represents an information source or sink. The kinetics of the engine is calculated self-consistently from the state of the nonequilibrium bath, and the relation of...

We study dynamics of a two-level system coupled simultaneously to a pair of dissimilar reservoirs, namely, a spin bath and a boson bath, which are connected via finite interbath coupling. It is found that the steady-state population transfer in the two-level system increases with its coupling to the spin bath, while optimal transfer occurs at intermediate coupling in the transient process. If t...

In this paper, a comparative study of the treatment of raw and biotreated (upflow anaerobic sludge blanket, UASB) textile dye bath effluent using advanced oxidation processes (AOPs) is presented. The AOPs applied on raw and biotreated textile dye bath effluent, after characterization in terms of COD, colour, BOD and pH, were ozone, UV, UV/H2O2 and photo-Fenton. The decolorization of raw dye bat...
