Feasibility study and CFD‐aided design for a new type oxidation ditch based on airlift circulation
Authors: Xu Nong , Fan Long , Pang Hongtao , Shi Hanchang 
Published: August 2010

AbstractA new type oxidation ditch, airlift oxidation ditch (ALOD), was designed based on the research about airlift reactors and fluidized beds. Three important functions: propulsion, oxygenation, and mixing, can be achieved simultaneously. The flow in this ALOD was simulated for the purpose of feasibility verification and preliminary design. The influences of the relative location of the clapboards, the distance between clapboard and surface, as well as the aerator array were discussed. A bench‐scale reactor was built to test the performance of the ALOD. All results provide evidence for the potential use of ALOD in municipal wastewater treatment.
Proposed kinetic mechanism of biodiesel production through lipase catalysed interesterification with a methyl acetate acyl acceptor and ionic liquid [BMIM][PF6] co‐solvent
Authors: Ruzich Nicholas Ivan , Bassi Amarjeet S. 
Published: August 2010

AbstractThe production of biodiesel was investigated using a lipase‐catalysed (Novozym 435) reaction involving methyl acetate and ionic liquid [BMIM][PF6] as a co‐solvent to produce an environmentally friendly, “green” process. Experiments were conducted at various amounts of ionic liquid. The reaction mechanism was examined through use of kinetic modelling and the effect of ionic liquid was studied for the first time. Studies indicated that the reaction followed a Ping–Pong Bi–Bi mechanism, and that the ionic liquid present in the system led to reduced initial reaction rates due to mass transfer limitations.
Use of zeolites in stabilising alkaline peroxide solutions and their application in the bleaching of a TMP pulp
Authors: Wekesa Moses , Ni Yonghao 
Published: August 2010

AbstractSilicate‐based chemistry is a common industrial practice to improve peroxide bleaching, however, the transition metal ion‐induced peroxide decomposition is still inevitable. In this study, we investigated the potential to further decrease the peroxide decomposition by adding zeolites to the silicate‐based peroxide system. The peroxide decomposition results showed that the combined effect of zeolites and sodium silicate is more effective than sodium silicate alone in decreasing the manganese‐induced peroxide decomposition. Two types of zeolites, X and Y, were studied. The bleaching experiments showed that an improved peroxide bleaching performance was obtained by adding Y‐zeolites to the conventional peroxide process.
A theoretical and experimental study of the crossflow microfiltration process of silica particles in an aqueous suspension
Authors: Räder Arlindo Soares , Tessaro Isabel Cristina , Marczak Ligia Damasceno Ferreira 
Published: August 2010

AbstractThis work presents a theoretical and experimental analysis of a crossflow microfiltration process of silica particles in suspension. The silica suspensions were 0.001 M of NaCl with a pH of 6 (to maintain a constant ionic force within the medium to produce a stable silica particle suspension) for three different concentrations of silica particles: 100, 300, and 500 mg L−1. The membrane used in the crossflow microfiltration experiments was a commercial polymeric membrane, microporous, asymmetric with a nominal pore diameter of 0.2 µm, manufactured by OSMONICS (Minnetonka, MN). The experiments were performed in a bench scale crossflow microfiltration system with a flat rectangular membrane cell. The permeate flux was obtained as a function of the transmembrane pressure, the crossflow velocities, and the silica particles concentration. The mathematical model describing the process takes into account the variation of the physical properties of the suspension (dynamic viscosity and mass diffusivity) with the silica concentration. The experimental data are used to predict the maximum silica concentration at the membrane surface as a function of the operating conditions.
Mathematical modelling of a solid particle motion in a re‐circulatory fluidised bed unit
Authors: Catak M. , Bas N. , Cronin K. , O'Brien S. , Byrne E. 
Published: August 2010

AbstractTwo fundamental properties of the particles are their velocity and consequent displacement versus time history during the granulation process. Knowledge of the particle velocity might supply much information about the sub‐processes. In this paper, an analytical model of a solid particle motion in an internal re‐circulatory fluidised bed unit is developed and validated against experimentally obtained data. The model predictions show good correspondence with the experimental results for the spherical particles. For the case of non‐spherical granules, the agreement between the model and the experiments is not equally convincing but still adequate.
Stage of breast cancer at diagnosis among low‐income women with access to mammography

Published: August 2010

AbstractBACKGROUND:This study assessed the relationship between area‐level poverty and stage of breast cancer at diagnosis among low‐income women when screening mammography was available at no cost.METHODS:The authors identified women diagnosed with breast cancer from 1999 to 2005 through the Massachusetts Cancer Registry, and compared the odds of advanced stage disease for women with low incomes (n = 546) for whom screening mammography and diagnostic services were available at no cost through the Massachusetts Breast and Cervical Cancer Early Detection Program, relative to a nonparticipating comparison group (n = 1287) residing in the same neighborhoods with similar distribution of age, race, and ethnicity as Massachusetts Breast and Cervical Cancer Early Detection Program participants. Among Massachusetts Breast and Cervical Cancer Early Detection Program participants, the odds of advanced stage disease were estimated by mammography use.RESULTS:Although screening mammography was available at no cost, only 36% of program participants diagnosed with breast cancer used screening mammography. Stage of breast cancer at diagnosis was not associated with area‐level poverty among Massachusetts Breast and Cervical Cancer Early Detection Program participants. For the comparison group, advanced stage disease was more likely for residents in high‐poverty areas, relative to low‐poverty areas (49% vs 37%,P< .01). The adjusted odds of advanced stage disease at diagnosis was greater for women aged 41 to 49 years, compared with those aged 50 to 64 years (P= .01).CONCLUSIONS:Programs that ensure breast cancer screening and diagnostic services are available at no cost to low‐income women can mitigate the adverse effect of area‐level poverty on stage of breast cancer. However, such programs require effective strategies to encourage use of screening mammography to promote diagnosis at an earlier stage. Cancer 2010. © 2010 American Cancer Society.

Published: August 2010

AbstractBACKGROUND:This study reports the adoption of prophylactic cranial irradiation (PCI) in patients with limited stage small cell lung carcinoma (LS‐SCLC) at Princess Margaret Hospital (PMH) and the factors that impact PCI utilization.METHODS:A retrospective review was performed on all patients with LS‐SCLC treated at PMH from 1997 to 2007. Clinical details including the rate of PCI utilization were determined and, for patients not receiving PCI, the documented reason was recorded. Brain failure free survival (FFS) and overall survival (OS) were estimated by the Kaplan‐Meier method, comparing patients treated with or without PCI. Pearson chi‐square test was used to determine factors associated with PCI use.RESULTS:Two hundred seven patients were treated for LS‐SCLC and 61.4% (n = 127) of these patients received PCI. The most common documented reason for not receiving PCI was patient refusal, typically because of concerns about PCI toxicity. Patients older than 65 were significantly less likely to receive PCI. Brain FFS and OS rates were significantly higher in patients who received PCI.CONCLUSIONS:Not all eligible patients are receiving PCI, despite its significant effect on reducing brain metastases and improving OS. Emphasizing the benefits of PCI to patients, when discussing potential toxicities, may improve utilization. Cancer 2010. © 2010 American Cancer Society.

Published: August 2010

AbstractBACKGROUND:Nausea and vomiting in patients with acute myelogenous leukemia (AML) can be from various causes, including the use of high‐dose cytarabine.METHODS:The authors compared 2 schedules of palonosetron versus ondansetron in the treatment of chemotherapy‐induced nausea and vomiting (CINV) in patients with AML receiving high‐dose cytarabine. Patients were randomized to: 1) ondansetron, 8 mg intravenously (IV), followed by 24 mg continuous infusion 30 minutes before high‐dose cytarabine and until 12 hours after the high‐dose cytarabine infusion ended; 2) palonosetron, 0.25 mg IV 30 minutes before chemotherapy, daily from Day 1 of high‐dose cytarabine up to Day 5; or 3) palonosetron, 0.25 mg IV 30 minutes before high‐dose cytarabine on Days 1, 3, and 5.RESULTS:Forty‐seven patients on ondansetron and 48 patients on each of the palonosetron arms were evaluable for efficacy. Patients in the palonosetron arms achieved higher complete response rates (no emetic episodes plus no rescue medication), but the difference was not statistically significant (ondansetron, 21%; palonosetron on Days 1‐5, 31%; palonosetron on Days 1, 3, and 5, 35%; P = .32). Greater than 77% of patients in each arm were free of nausea on Day 1; however, on Days 2 through 5, the proportion of patients without nausea declined similarly in all 3 groups. On Days 6 and 7, significantly more patients receiving palonosetron on Days 1 to 5 were free of nausea (P = .001 and P = .0247, respectively).CONCLUSIONS:The daily assessments of emesis did not show significant differences between the study arms. Patients receiving palonosetron on Days 1 to 5 had significantly less severe nausea and experienced significantly less impact of CINV on daily activities on Days 6 and 7.
