sive, be easy to apply and remove, ensure the security of the drain and maximize patient comfort. These goals are achievable, but often drain security is prioritized at the expense of patient comfort and practicality. We have found an effective method for dressing sutured drains with the use of a single “All-In-One” dressing or a 20 × 10-cm adhesive-absorbent pad (Primipore; Smith & Nephew, St....

A new composite absorbent with multifunctional and environmental-friendly structures was prepared using chitosan, diatomite and polyvinyl alcohol as the raw materials, and glutaraldehyde as a cross-linking agent. The structure and morphology of the composite absorbent, and its adsorption properties of Hg(II) in water were characterized with Fourier transform infrared (FT-IR) spectra, scanning e...

The acoustic behavior of perforated dissipative circular mufflers with empty extended inlet/outlet is investigated in detail by means of a two-dimensional (2D) axisymmetric analytical approach that matches the acoustic pressure and velocity across the geometrical discontinuities, and the finite element method (FEM). The complex characteristic impedance, wavenumber, and perforation impedance are...

Increasing CO2 gas emissions results in climate change by increasing air temperature and worsening environmental problems. It is necessary to control the overcome this. This research aims optimize absorption of with 0.1 M NaOH absorbent column Raschig ring stuffing material using response surface methodology (RSM). was conducted a continuous system three independent variables varying contact ti...

Antimicrobial surfaces can be applied to break transmission pathways in hospitals. Polyaniline (PANI) and poly(3-aminobenzoic acid) (P3ABA) are novel antimicrobial agents with potential as non-leaching additives to provide contamination resistant surfaces. The activity of PANI and P3ABA were investigated in suspension and as part of absorbent and non-absorbent surfaces. The effect of inoculum s...

A new biomimetic absorbent, cellulose acetate (CA) embedded with triolein (CA-triolein), was prepared and applied for the removal of persistent organic pollutants (POPs) from micro-polluted aqueous solution. The comparison of CA-triolein, CA and granular activated carbon (GAC) for dieldrin removal was investigated. Results showed that CA-triolein absorbent gave a lowest residual concentration a...

The aim of the current research is to examine the potential of locally available natural clay mineral to act as an effective absorbent for waste engine oil treatment. The clay mineral was collected from the southern region of Saudi Arabia and was used without any kind of surface modification. The clay mineral was characterized by X-ray diffraction (XRD), X-ray fluorescence (XPS) and Braunner-Em...

the notion of absorbent ordered filters in implicative semigroupsis introduced, and its fuzzification is considered. relations among (fuzzy) orderedfilters, (fuzzy) absorbent ordered filters, and (fuzzy) positive implicativeordered filters are stated. the extensionproperty for (fuzzy) absorbent orderedfilters is established. conditions for (fuzzy) ordered filters to be (fuzzy)absorbent ordered ...
