Characterization and synthesis of some alternating terpolymers of maleic anhydride
(MATRICE TECHNOLOGY LIMITED, 2004)
In this study, MA-S-MMA, MA-S-VA and MA-S-AP terpolymers have been synthesized in methyl ethyl ketone from methyl methacrylate (MMA), vinyl acetate (VA), allyl propionate (AP), styrene (S), and maleic anhydride (MA) monomers ...
Optimization of Pb flotation using statistical technique and quadratic programming
(ELSEVIER SCIENCE BV, 2008)
A three-level Box-Behnken factorial design combining with a response surface methodology (RSM) was employed for modeling and optimizing three operations parameters of the flotation on lead flotation. The flotation studies ...
Tuberculous pericarditis: A report of three cases
(TAYLOR & FRANCIS LTD, 2001)
Three cases with the rare condition of tuberculous pericarditis are reported.
Effect of climate on the bacteriology of chronic suppurative otitis media
(ANNALS PUBL CO, 2005)
Objectives: We evaluated the correlation between the microbial content of chronic suppurative otitis media (CSOM) and regional climatic parameters. Methods: We assessed the interrelations between monthly mean records of ...
Poly(acrylamide-sepiolite) composite hydrogels: Preparation, swelling and dye adsorption properties
(SPRINGER, 2006)
Polymer-clay hydrogel composite was prepared on the basis of polyacrylamide (PAAm) gel containing the clay mineral sepiolite. The properties of swelling and dye adsorption of poly(acrylamide-sepiolite) (AAm/Sep) composite ...
Biological phosphorus removal in a sequencing batch reactor by using pure cultures
(ELSEVIER SCI LTD, 2005)
The aim of this study was to investigate the effect of pure cultures on the enhancement of biological phosphorus removal capability of a Sequencing Batch Reactor (SBR) inoculated initially with a mixed culture. For this ...
Adaptive heuristic temperature control of a batch polymerisation reactor
(ELSEVIER SCIENCE SA, 2004)
The purpose of this research is to improve and apply the temperature control of a free radical solution polymerisation of styrene and to examine its performance on the basis of adaptive heuristic criticism (AHC) control. ...
Utilisation of personal protective equipment in dental practice
(WILEY, 2003)
Objective: To investigate personal protective equipment such as gloves, mask and protective eye wear used in dental practice in Turkey. Design: An e-mail based self-report questionnaire was sent to dentists during 2002. ...
Assessment of the effect of a biphasic ceramic on bone response in a rat calvarial defect model
(WILEY-LISS, 2006)
Calcium phosphate ceramics are being extensively used for orthopedic, periodontal, and dental applications. This Study aimed to assess the effect of a biphasic ceramic such as Ceraform (R) on the osteogenesis in a rat ...
Ammonium oxidation via nitrite accumulation under limited oxygen concentration in sequencing batch reactors
(ELSEVIER SCI LTD, 2009)
In this study, the effects of sludge retention time (SRT) on NH(4)-N oxidation and NO(x)-N accumulation in the nitritation reactors were studied. The gradually decrease of SRT also caused long reaction time to achieve 99% ...
