Abstract:
Abstract The aim in this study was to evaluate the influence of different ratio of camphorquinone/tertiary amine concentration on the flexural strength (FS), elastic modulus (EM), degree of conversion (DC), yellowing (YL), water sorption (WS) and water solubility (WSL) of experimental composites. Thus, acrylate blends were prepared with different camphorquinone (CQ) and amine (DABE) concentrations and ratios by weight: (CQ/DABE%): 0.4/0.4% (C1), 0.4/0.8% (C2), 0.6/0.6% (C3), 0.6/1.2% (C4), 0.8/0.8% (C5), 0.8/1.6% (C6), 1.0/1.0% (C7), 1.0/2.0% (C8), 1.5/1.5% (C9), 1.5/3.0% (C10).

Abstract:
Analysis of the impacts of nitrogen, phosphorus and potassium supplementation on biofilter performance for organic carbon removal was studied on laboratory-scale biofilter columns. Three dual media biofilter columns were fed with synthetic raw water C:N:P ratios of 546:24:1, 100:10:1, and 25:5:1 (w/w) to simulate nutrient limited and two nutrient supplemented conditions, respectively. Research found that air-scour versus water only backwash improved the nutrient limited dissolved organic carbon (DOC) removal by 8%. In addition, nutrient supplementation and backwash alteration improved DOC remo

Abstract:
Rice is the essential food crop of An Giang Province. Vietnam and the whole world are facing several problems hindering climate change, such as increased temperature and CO2 concentration that many manufacturers’ companies and managers need to estimate output to make production plans or adjust policies. In this study, the model known as SIMPLE was applied to simulate the biomass and yield of rice in 2 crop seasons Autumn - Winter 2020 (AW) and Winter - Spring 2020 - 2021 (WS), in Cho Moi district, An Giang province, Vietnam (10° 23' 47"N, 105° 27' 41"E) and analyzed the effects of climate vari

The fungus Pleospora papaveracea is a potential biocontrol agent for opium poppy. The objective of this study was to characterize the growth and production of propagules of P. papaveracea on various substrates and determine their infectivity on opium poppy. Pleospora papaveracea was grown on agar media containing wheat bran, corn cobs, soy fiber, cottonseed meal, rice flour, cornstarch, pectin, dextrin, or molasses, all with the addition of brewer's yeast (BY). Maximum radial growth of P. papaveracea occurred on molasses, soy fiber, and wheat bran media. Pleospora papaveracea produced chlamydo

Abstract:
Abstract The contamination of natural resources with mercury has gained attention due to its high toxicity to all life forms. Bioremediation of mercury using bacteria is a useful technique to remediate mercury contamination. In the present study mercury resistant bacteria (MRB) were isolated from Mithi River water samples. Total heterotrophic bacteria (THB) and MRB present in the Mithi river water samples were enumerated. The count for THB was found to be 3.7 × 106 CFU/ml. MRB enumerated in the nutrient agar medium with mercury concentrations of 50, 100 and 150 ppm had counts of 2.8 × 106, 9.1

Abstract:
“Biofouling” is a biofilm problem which is operationally defined. It applies to biofilms which exceed a given threshold of interference. If this is the case, countermeasures are taken. However, conventional antifouling strategies are hampered by some intrinsic problems which can identified as follows: (1) there are no early warning systems, (2) detection of biofouling is not performed on surfaces but by analysis of water samples which will not indicate site or extent of biofilms, (3) disinfection is misunderstood as cleaning, (4) nutrients are not limited although they must be considered as po

Abstract:
With the purpose of destroying helminth eggs, laboratory tests were carried out using a batch reactor of 1 L with 500 mL of eggs in suspension (1 × 105 eggs/L). In all the tests, a 36.8 mg O3/L concentration of gas-phase ozone was applied at the bottom of the reactor, with flows of 0.25 and 0.5 L/min to achieve rates of 9.2 and 18.4 mg O3/min, respectively. The results (first stage) showed that the eggs of Ascaris suum were destroyed at a pH of less than 5, with a dose of 18.4 mg O3/min., giving a 94% success rate; these results were improved when applying a pH 3 (second stage) with 18.4 mg O3

ABSTRACTFour silages were prepared from a sward of perennial ryegrass (Lolium perenne cv. Melle). Two were ensiled directly either without (UWN) or with formic acid at 31 1/t fresh material (UWA). The remaining herbage was left undisturbed in the swath for 43 h (WL) or was spread and harvested after 19 h (WS). The dry matter (DM) concentrations at harvest for the unwilted herbage were 229 (UWN) and 238 g DM per kg (UWA) and wilting increased DM concentration to a similar extent for both treatments (WS, 339 v.
