Synergistic Effect of Ag <sub>2</sub> O@CuO Photocatalyst in Engineering Highly Hydrophilic Photocatalytic Membranes With Superior Self‐Cleaning Properties for Organic Dyes Elimination
...Show More Authors
ABSTRACT<p> Polyvinyl chloride (PVC) ultrafiltration membranes were efficiently fabricated using a (0.1–0.5 wt.%) Ag <sub>2</sub> O@CuO heterojunction photocatalyst to form a PVC/Ag <sub>2</sub> O@CuO photocatalytic membrane (PM) stimulated by UV light. The PVC/Ag <sub>2</sub> O@CuO PM fabricated using the phase inversion process resulted in significant improvement in internal morphology, porosity, pure water flux, and separation efficacy of the doped membranes. The efficacy of the PVC/Ag <sub>2</sub> O@CuO PMs was evaluated in the elimination of Rhodamine B (RhB) dye. The highest photodegradation of RhB (96.9%) was obtained using the PM2 membrane that contains 0.3 wt.% Ag <sub>2</sub> O@CuO photocatalyst at an influent pH of 6.5, a feed RhB concentration of 5 mg/L, a RhB solution volume of 2000 mL, an influent flow rate of 1 L/min under UV light irradiation for 90 min. PM2 membrane demonstrated antifouling features in terms of flux recovery ratio, reversible fouling, irreversible fouling, and total fouling, and 90% of RhB was removed after five cycles of use. The kinetic results indicated that the photocatalytic oxidation of RhB dye by the PM2 membrane followed the pseudo‐first‐order kinetic model, with an apparent rate constant of 0.0289 min <sup>−1</sup> . Studying the Langmuir–Hinshelwood model resulted in an intrinsic photocatalytic reaction rate constant of 0.7666 mg/L.min and an equilibrium adsorption constant of 0.045 L/mg. </p>

Extra-Anatomic prosthetic bypass grafts in management of Sub-inguinal vascular infections
...Show More Authors

Infection at the site of vascular anastomosis is a serious complication of vascular surgery and is associated with a high limb loss and mortality rate. The classical method of management is ligation of the injured artery, adequate wound debridement and restoration of circulation. The latter is achieved by either in situ or extra-anatomic bypass. If the distal circulation is not maintained, subsequent amputation is most likely.
Objectives: In this study we tried to assess the efficacy of extra-anatomic synthetic bypass grafts in the treatment of vascular infection in the groin to save the limb and avoid the inevitable amputation.
Methods: Between January 2006 and December 2007, ten male patients aged twenty to thirty five years (mea

Gamma ray effect on the properties of R590 and C480 laser dyes
...Show More Authors

In the current research, we investigated the absorption spectrum for R590 and C480 dyes in ethanol solvent for different dye solution concentrations of 10-4, 10-5 and 10-6M. These dyes have been prepared and studied before and after gamma irradiation (first, second ionization) using cesium-137 source with absorbed doses of 18.36 Gy (time exposure of 10 days) and 73.44 Gy (with time exposure of 40 days). We noticed that the absorption intensity was decreased with decreasing concentration, before gamma irradiation while the absorption spectrum peak shifted towards the short wavelength (blue shift). It was also found that the intensity of absorption spectrum increased and shifted the absorption spectrum peak towards the long wavelength (red

Emotion Recognition Based on Mining Sub-Graphs of Facial Components
...Show More Authors

Facial emotion recognition finds many real applications in the daily life like human robot interaction, eLearning, healthcare, customer services etc. The task of facial emotion recognition is not easy due to the difficulty in determining the effective feature set that can recognize the emotion conveyed within the facial expression accurately. Graph mining techniques are exploited in this paper to solve facial emotion recognition problem. After determining positions of facial landmarks in face region, twelve different graphs are constructed using four facial components to serve as a source for sub-graphs mining stage using gSpan algorithm. In each group, the discriminative set of sub-graphs are selected and fed to Deep Belief Network (DBN) f

Influence of concentration on the structural, optical and electrical properties of TiO 2 : CuO thin film Fabricate by PLD
...Show More Authors

In this work, Titanium oxide thin films doped with different concentration of CuO (0,5,10, 15,20) %wt were prepared by pulse laser deposition(PLD) technique on glass substrates at room temperature with constant deposition parameter such as : pulse (Nd:YAG), laser with λ=1064 nm, constant energy 800 mJ , repetition rate 6 Hz and No. of pulse (500). The structure , optical and electrical properties were studied . The results of X-ray diffraction( XRD) confirmed that the film grown by this technique have good crystalline tetragonal mixed anatase and rutile phase structure, The preferred orientation was along (110) direction for Rutile phase. The optical properties of the films were studied by UV-VIS spectrum in the range of (360-1100)

Creating a LabVIEW Sub VI for the INA219 sensor for detecting extremely low-level electrical quantities
...Show More Authors

An impressed current cathodic protection system (ICCP) requires measurements of extremely low-level quantities of its electrical characteristics. The current experimental work utilized the Adafruit INA219 sensor module for acquiring the values for voltage, current, and power of a default load, which consumes quite low power and simulates an ICCP system. The main problem is the adaptation of the INA219 sensor to the LabVIEW environment due to the absence of the library of this sensor. This work is devoted to the adaptation of the Adafruit INA219 sensor module in the LabVIEW environment through creating, developing, and successfully testing a Sub VI to be ready for employment in an ICCP system. The sensor output was monitored with an Arduino
