This paper presents a biological method for controlling odor problems caused by H2S originating from sewer networks under anaerobic conditions. The proposed method is based on the continuous addition of nitrate which oxidizes dissolved sulphide according to an autotrophic biological procedure and inhibits further sulphide production by sulphate reducing bacteria, until complete denitrification....

Three diflerent juice extractor settings were used to obtain juice from Hamlin oranges. Cloud in Sofi and Medium extracted juice had nearly identical A, values. The A, of the Hard extracted juice was greater than the others. At 30C A, for both the Sofi and Medium juice increased slightly over time while the Hard juice A, decreased. The cloud in all three raw juices showed a decrease in A , at 4...

Inertial pumping is a promising new method of moving fluids through microchannels but many its properties remain unexplored. In this work, inertial flow rates are investigated for different channel lengths, operating temperatures, and resistor pulse energies. Flow in closed channels visualized by adding fluorescent tracer beads to the test fluid (pure water). A robust methodology extracting fro...

Generation of controls with a single DSB in a single chromosome per cell. When shifted to restrictive temperature, cells with a temperature-sensitive replication-initiation defective mutation, such as dnaA(TS), continue to divide until most contain a single chromosome [Supplementary Fig. 1]. We exploited this property to generate cells with a single chromosome so that we could assess the abilit...

Objectives: The present investigation aimed at examining if post-cancer treatment with a potentized homeopathic drug, Condurango 30C, which is generally used to treat oesophageal cancer, could also show an ameliorating effect through apoptosis induction on lung cancer induced by benzo[a]pyrene (BaP) in white rats (Rattus norvegicus). Methods: Lung cancer was induced after four months by chronic...

This study was conducted to assess the post thaw quality of Kundhi buffalo semen diluted in tris based diluents. After collection the ejaculates were pooled and checked for color, volume, pH, mass activity, progressive linear motility% (PLM), and intactness of cell membrane. The semen qualifying these tests was divided into four aliquots A, B, C and D, diluted with tris based diluents; the last...

This paper presents the results of a study undertaken in Dublin, to ascertain passenger preferences for public transport information. The study examines the need for public transport information across three stages of a public transport trip. The stages examined are as follows; stage one: pre-trip planning from home to work, stage two: at-stop/station information, and stage three: pre-trip plan...

The present study was on isolation of a potent fungal strain from mangrove sediment for the optimization and production of uricase enzyme. Among the 6 fungal strains isolated, Aspergillus niger was found to be a potent uricase producer and it was further used for the optimization studies for uricase production. The optimum cultural parameters that were found to be ideal for the higher uricase p...

The adsorption of polyacrylic acid (PAA) on hydroxyapatite (HAP) from HAP saturated solutions was studied in this work as a function of PAA concentration, temperature, pH and ionic strength. In all experiments, the adsorption was studied under conditions of negatively charged adsorbent and adsorbate, respectively. These conditions ensured that adsorption was not electrostatically favored. The s...
