Publication Abstract:
LM Abdulhadi
A 70-year-old man who suffered from extensive extra and intraoral defects was rehabilitated with a prosthesis using multiple retaining means. The treatment was performed in two parts: externally involving the construction of an episthesis supported only by the remaining intact boundaries of the defect and retained by mini-dental implants and spectacle frame with a modified ear hook; and intraorally by an acrylic resin obturator to restore the function of the hemi-sectioned hard and soft palate. The episthesis was securely retained with minimal movement and/or dislodgment of the prosthesis during function. Multiple retentive techniques may be used to fix heavy external prostheses as an alternative to conventional implants or biological adhesives. Keywords: anaplastology, midface replacement, mini-dental implant, ear hook

Publication Abstract:
Determination of Residence Time Distribution (RTD), oxygen volumetric mass transfer coefficient (kLa) and mixing pattern in an Internal Loop Airlift Reactor (ILALR) for both living and nonliving systems have been investigated in this paper. Optimal operating condition is found at a gas flow rate of 2 l min−1. The estimated kLa values for nonliving and living system at 27°C are 0.004 s−1 and 0.017 s−1 respectively. Batch biodegradation of phenol with an initial concentration of 300 mg l−1 by the mixed microbial culture occurs at a very high degradation rate (0.16 mg l−1 h−1).

Publication Abstract:
This research work investigates the composition effect on the fabrication and morphological characteristics of a hybrid polymeric solar cell which consists an electron donating conjugated polymer, namely is poly(3-hexylthiophene) (P3HT) combined with an electron-accepting component, which is a type of inorganic compound of TiO2 nanocrystals. The composition of TiO2 in the blends is varied and the optimum performances of the devices are studied. The optical and morphological characterizations of the samples are carried out via UV-Visible absorption spectroscopy, X-ray diffraction (XRD) spectroscopy, Atomic Force Microscopy (AFM) and Scanning Electron Microscopy (SEM), whereas the electrical characterizations of the devices are measured by using Keithley 2400 SMU and solar simulator with light intensity of 100mW/cm2.

Publication Abstract:
Values lie at the core of all human behavior. Initially, it was believed that human behavior could be best explained in terms of one¿s personality system, including needs, motives, beliefs, goals and attitudes. But eventually, the emphasis shifted towards values, as there are many aspects of human behavior that cannot be attributed to the former concepts, but where values play an important role. The authors believe that values make personnel life more meaningful and give them a sense of direction for organizational performance and development. In this article, the authors have discussed the sources of values, early assumptions about values, a value based approach to organizations and value assessment. Recommendations have also been offered for the human resource managers to inculcate spiritual values among personnel that may in turn be fruitful for organizational development.

Objective: To evaluate oral pyridoxine in conjunction with standard therapy in women hospitalized for hyperemesis gravidarum (HG).
Methods: Patients with HG were randomized at hospitalization to 20 mg oral pyridoxine thrice daily or to placebo. Intravenous rehydration, metoclopramide and oral thiamine were also administered. Metoclopramide and thiamine were continued for 2 weeks after discharge. Rehospitalization for HG in the 2-week study period was ascertained, vomiting was recorded by diary, and nausea was evaluated with a 10-point visual analogue scale (VAS) at enrolment, after hospital discharge and on week 1 and 2 reviews.
Results: Ninety-two women were included in the analysis. The rehospitalization rate was 37.5 versus 21.1% (relative risk 1.8, 95% confidence interval 0.9-3.7, p = 0.14) for pyridoxine and placebo, respectively. Daily vomiting episodes after discharge were not different (mean ± SD): 1.9 ± 2.4 versus 1.4 ± 1.1, p = 0.28 during week 1 and 1.4 ± 1.3 versus 1.4 ± 1.6, p = 0.98 during week 2. Repeated-measures analysis of variance showed no difference in the nausea visual analogue scale (p = 0.59).
Conclusion: The use of oral pyridoxine in conjunction with metoclopramide during the inpatient stay and during the 2 weeks after hospital discharge for hyperemesis gravidarum did not improve the rehospitalization rate, the vomiting frequency or the nausea score. Larger studies need to be done.
