Medical health knowledge management using wireless network: Moroccan hospitals case study

Hospitals and medical health services are large business that we have to make them successful for their earned profits and incomes. Unifying the communication in hospitals can approve the environments and avoid the problems faced. Wireless networks are very useful in large crowded places like hospitals. Wireless technology has empowered the medical health systems by reducing the paperwork that nurses or doctors have to deal with them whole day. Its primary purpose is to ensure effective care of patients by increasing the accuracy and speed of health care. This paper highlights patients' knowledge management in hospitals using the wireless communication since the rate of medical errors has increased lately. The intention of this paper is to utilize an advanced technology to help hospitals raise the rate of care of patients throughout the use of mobile data collection device that transmits data to a centralized database to raise the visibility of data to the receivers

Care of Mechanical Ventilated Patients in General Ward: Nurses Perspective

Aim: This study aimed to explore the care of mechanically ventilated patients in general wards from the nurses' perspective.Methodology: A cross-sectional descriptive study using a self administered questionnaire was given to the nurses with a purposive convenient sampling method in adult patients from medical, surgical and isolation units in studied hospital in KSA. Results: 149 participants from general units represents various years of experiences shared their perception on the knowledge and competencies (M= 3.38±.62) the support they received (M= 2.41±.78), their satisfaction and confidence (M= 2.86±.81) and the resources provided (M= 2.44 ±.69) for caring MV patients in their general unit revealed the total mean in each categories were in the state of either neutral or disagree with the items given. The participants admitted that the found themselves are competent in performing suctioning with aseptic technique and ability to identify the possible complications confidently. However the participant concluded that it was inadequate support for them, staffing ratio, equipment and facilities was inappropriate which leads to dissatisfaction and less confident in caring for MV patients.Conclusion: This study concludes that caring for patients in general ward causing dissatisfaction among the staff and place patients in risk. Hospital administration needs to ensure that general ward nurses are trained accordingly, provide adequate staffing ratio, and prepare the physical environment and suitable equipment to care for MV patients in general ward

Performance evaluation of reverse osmosis (RO) pre-treatment technologies for in-land brackish water treatment

Integration of renewable energy with desalination technologies has emerged as an attractive solution to augment fresh water supply sustainably. Fouling and scaling are still considered as limiting factors in membrane desalination processes. For brackish water treatment, pre-treatment of reverse osmosis (RO) feed water is a key step in designing RO plants avoiding membrane fouling. This study aims to compare at pilot scale the rejection efficiency of RO membranes with multiple pre-treatment options at different water recoveries (30, 35, 40, 45 and 50%) and TDS concentrations (3500, 4000, and 4500mg/L). Synthetic brackish water was prepared and performance evaluation were carried out using brackish water reverse osmosis (BWRO) membranes (Filmtec LC-LE-4040 and Hydranautics CPA5-LD-4040) preceded by 5 and 1μm cartridge filters, 0.02μm ultra-filtration (UF) membrane, and forward osmosis (FO) membrane using 0.25M NaCl and MgCl2 as draw solutions (DS). It was revealed that FO membrane with 0.25M MgCl2 used as a draw solution (DS) and Ultra-filtration (UF) membrane followed by Filmtec membrane gave overall 98% rejection but UF facing high fouling potential due to high applied pressure. Use of 5 and 1μm cartridge filter prior to Filmtec membrane also showed effective results with 95% salt rejection

On diversity performance of two-element coupling element based antenna structure for mobile terminal

In wireless communication systems, multipath interference has a significant impact on system design and performance. Fast fading is caused by the coherent summation of one or more echoes from many reflection points reaching the receive antenna. Antenna diversity can be used to mitigate multipath fading. The main challenge of antenna diversity in practical application is the integration of multiple antennas on a small ground plane. Two-element antenna structure based on coupling element antenna concept for diversity application has been studied in previous work and it has shown to be feasible for low frequency diversity application with stable and low envelope correlation across wide frequency range. The studied structure has been tuned to be operating at 1600 MHz for measurement evaluation purpose. This paper presents an analysis of diversity performance of the structure in terms of efficiencies, envelope correlation, and apparent and effective diversity gains in isotropic (i.e. statistically uniform) propagation channel, using spherical near-field technique in an ideal line-of-sight environment (anechoic chamber) and inside reverberation chamber. The envelope correlation is less than 0.1 and the diversity gain is equal to 10.2 dB at 99% reliability level using selection combining technique across simulation and both measurement methods. The measurement techniques are compared to show how accurately the diversity performance of a mobile terminal antenna can be estimated

In vitro characterisation of probiotic properties of Enterococcus faecium and Enterococcus durans strains isolated from raw milk and traditional dairy products

WOS: 000486322600001In this study, some probiotic characteristics such as antimicrobial activity, vancomycin resistance, growth ability at pH, resistance to bile salts, bile salt deconjugation and hydrophobicity of 30 Enterococcus faecium and Enterococcus durans strains isolated and identified from raw milk and various dairy products were investigated. According to the study results, antimicrobial activity profiling, pH and bile salt resistance and bile salt deconjugation ability of Enterococcus strains varied depending on the species and strains and all the strains showed resistance to the tested bile salt concentrations. It was concluded that the E. faecium and E. durans strains tested showed probiotic characteristics and have the potential to be used in food production.Ege University Scientific Research FundEge University [2011-ZRF-010]The present study was funded by Ege University Scientific Research Fund (Project Number: 2011-ZRF-010) and presented as a poster proceeding at the 'The 2nd International Symposium on "Traditional Foods from Adriatic to the Caucasus"' held between 24 October and 26 October 2013
