This paper reviews both heterotrophic and autotrophic processes for the removal of nitrate from water supplies. The most commonly used carbon sources in heterotrophic denitrification are methanol, ethanol and acetic acid. Process performance for each feed stock is compared with particular reference nitrate and nitrite residual and to toxicity potential. Autotrophic nitrate removal has the advan...
BACKGROUND Current standard neoadjuvant treatment for advanced ovarian cancer is 3-weekly platinum-based chemotherapy (CP3w). Patients unable to have interval debulking surgery (IDS) or with significant residual disease have a poor outcome to CP3w treatment. We investigated the outcome in patients who were switched to dose-dense chemotherapy. METHODS We retrospectively analysed 30 patients tr...

An important problem – patients with relapses disease, as well children persistence minimal residual disease (MRD), which absolutely necessary in hematopoietic stem cell transplantation aspects.

abstract background: the current practice to measure rv is either by bpg or helium dilution methods which may not be available in all clinics due to their cost. methods: this paper outlines a method for both direct and indirect calculation of rv via pft with acceptable sensitivity (81 %, 60% ), specificity (71 %, 94%) and validity (76%, 78%) for obstructive and restrictive lung disease respecti...
Abstract The objective was to evaluate the residual action of insecticides acetamiprid + etofenprox, spinetoram, indoxacarb and methoxyfenozide on predator Chrysoperla externa Hagen, 1861 (Neuroptera: Chrysopidae). bioassays followed methodologies proposed by International Organization for Biological Integrated Control (IOBC). were sprayed grapevine plants cv. Burgundy, using maximum recommende...
