    Preparation of Polysulfone Capillary Ultrafiltration Membranes for Pre-treatment of Sea Water Reverse Osmosis and Studies on its Fouling behavior after Turbidity Removal from Sea Water

    V. S. MAMTANI, A. K. GHOSH*, R. C. BINDAL

    Journal of Polymer Materials, Vol.39, No.1-2, pp. 137-149, 2022, DOI:10.32381/JPM.2022.39.1-2.9

    Abstract In this study, polysulfone based capillary ultrafiltration membranes with desired characteristics were indigenously developed and their performance was evaluated with respect to turbidity removal from raw sea water. Capillary membranes were spun with in-house fabricated spinneret using polymer casting solution (dope solution) of different compositions having different viscosity using polyvinyl pyrrolidone (PVP) as pore-forming agent. Different experimental conditions namely dope pressure, bore fluid flow rate and air gap distance are optimized to get membranes of desired properties. Test results of individual capillaries in terms of pure water permeability (PWP), separation of single uncharged solutes like… More >

    Ameliorative Role of Pre-Sowing Proline Treatment in Coriandrum sativum L. Seedlings under Mercury Toxicity

    Dhriti Kapoor1, Kapani Kavani1, Amandeep Rattan2, Marco Landi3,*, Anket Sharma4,*

    Phyton-International Journal of Experimental Botany, Vol.90, No.2, pp. 489-501, 2021, DOI:10.32604/phyton.2021.012359 - 07 February 2021

    Abstract Heavy metal toxicity is one of the major ecosystem concerns globally in present time and is also responsible for significant threat to agronomic crops. The current work was conducted to investigate the possible ameliorative role of proline in Coriandrum sativum L. seedlings treated with mercury (Hg). The seedlings were exposed to different concentrations of Hg (0, 0.1, 0.3 and 0.5 mM) for 20 days. The effects of pre-sowing treatment with proline were studied on C. sativum seedlings in terms of pigment (chlorophylls, carotenoids and anthocyanins), malondialdehyde (MDA), antioxidant compound (glutathione, total phenolic compounds, ascorbic acid) and osmolytes… More >

    Differential Catalysis of Depolymerisation and Dehydration Reactions: Producing Furfural from Plant Biomass

    Nikolajs Vedernikovs*

    Journal of Renewable Materials, Vol.8, No.6, pp. 661-674, 2020, DOI:10.32604/jrm.2020.09274 - 12 May 2020

    Abstract The main principles of the technological realisation of the furfural obtaining process have been formulated by Ricard [1]. Based on his recommendations, all investigators proceeded from the assumption that the depolymerisation of pentosans and the dehydration of pentoses in the one-step production of furfural from raw plant material must be accelerated with diluted catalyst solutions. According to this theory, uniform impregnation of the raw material with a catalyst solution is considered necessary. The reduction in the amount of the catalyst solution down to 30–40% of the mass of the dry raw material, suggested by Miner… More >

    A comparative analysis of prostate cancer pre-treatment characteristics stratified by age

    Navin Shah1, Vladimir Ioffe2, Anish Kapur3

    Canadian Journal of Urology, Vol.21, No.2, pp. 7213-7216, 2014

    Abstract Introduction: To compare the pretreatment characteristics of prostate cancer, prostate-specific antigen (PSA), digital rectal examination (DRE) and Gleason sum score (GSS) by the American Urological Association (AUA) stratified age groups, <55, 55-69 and ≥70 years old.
    Materials and methods: A retrospective analysis of 402 sequential prostate cancer patients, who had transrectal ultrasound guided 12 core prostate biopsy for either elevated PSA (over 2.5 ng/mL) or positive DRE or both during a three year period, 2010 to 2012. There were 36 patients <55 years, 226 patients 55 to 69 years and 140 patients ≥70 years (range 44-78… More >

    Outcome analysis of prostate cancer patients with pre-treatment PSA greater than 50 ng/ml

    Ericka Wiebe1, George Rodrigues1,2, Michael Lock1, David D’Souza1, Larry Stitt2

    Canadian Journal of Urology, Vol.15, No.3, pp. 4078-4083, 2008

    Abstract Introduction: The optimal management of prostate cancer patients presenting with prostate specific antigen (PSA) levels greater than 50 ng/ml is controversial. The purpose of this study was to investigate factors associated with overall survival and biochemical outcome in a high-risk prostate cancer population with PSA > 50.0 ng/ml at time of diagnosis, and no clinical or radiological evidence of metastatic disease.
    Materials and methods: A single institution chart review was conducted at the London Regional Cancer Program on 138 patients who presented with PSA levels greater than 50 ng/ml. Forty-eight (34.8%) of these patients had no clinical… More >
