BACKGROUND Substantial progress in reducing the child mortality rate has been made globally in the last two decades. However, for China, the number of children dying from preventable diseases is still very large. It is important to have regularly updated information on the distribution of causes of death (COD) in children to inform policy and research. In this study, we aim to estimate the COD ...

One of the most iconic Australian fish is the Murray cod, Maccullochella peelii (Mitchell 1838), a freshwater species that can grow to ∼1.8 metres in length and live to age ≥48 years. The Murray cod is of a conservation concern as a result of strong population contractions, but it is also popular for recreational fishing and is of growing aquaculture interest. In this study, we report the whole...

The applicability of Fenton's oxidation as an advanced treatment for chemical oxygen demand (COD) and color removal from anaerobically treated poultry manure wastewater was investigated. The raw poultry manure wastewater, having a pH of 7.30 (+/-0.2) and a total COD of 12,100 (+/-910) mg/L was first treated in a 15.7 L of pilot-scale up-flow anaerobic sludge blanket (UASB) reactor. The UASB rea...

The treatment of domestic sewage at low temperature was studied in a two-anaerobic-step system followed by an aerobic step, consisting of an anaerobic filter (AF) + an anaerobic hybrid (AH) + polyurethane-foam trickling filter (PTF). The AF+AH system was operated at a hydraulic retention time (HRT) of 3+6 h at a controlled temperature of 13 degrees C, while the PTF was operated without wastewat...

OBJECTIVES This study aims to investigate the adhesion characteristics between submicron calcium oxalate dihydrate (COD) with a size of 150 ± 50 nm and African green monkey kidney epithelial cells (Vero cells) before and after damage, and to discuss the mechanism of kidney stone formation. METHODS Vero cells were oxidatively injured by hydrogen peroxide to establish a model of injured cells. ...

The decentralised treatment of concentrated sewage (about 3,600 mgCOD/l) at low temperature was investigated in a two-step anaerobic system: two-anaerobic hybrid (AH) septic tanks (each 0.575 m3). The two reactors were placed in a temperature controlled-room and the HRT was 2.5 days for each reactor. The system was fed with concentrated domestic sewage, mainly black water from about 40 toilets ...

Feature selection is problematic when the number of potential features is very large. Absent distribution knowledge, to select a best feature set of a certain size requires that all feature sets of that size be examined. This paper considers the question in the context of variable selection for prediction based on the coe!cient of determination (CoD). The CoD varies between 0 and 1, and measure...

To meet the increasing demand for value-added fresh cod loins in the EU retail market, it is important to develop new technologies and preservation methods to effectively extend the shelf-life and improve the eating quality of fresh cod loins. The aim of this study was to investigate the effects of combined application of MAP and superchilled storage on the shelf-life extension of fresh cod loi...

Pilot plant study showed that there is a relationship between the HRT in aeration tank and the % removal of soluble COD in the final settler if DO is not a limiting function. It was found that the % removal of soluble COD in final settler increased from 13 at HRT in aeration tank of 12 hours to 45 at HRT of 4 hours. Mathematical model was also presented in order to predict the soluble COD utili...

Brewing is the process is for production of beer [1,2]. It is said that for every 1 liter of beer production approximate 10 liters of water is used [3]. The water in any brewery is typically used for brewing, rising and cooling process [3]. The various steps that are involved in brewing process are malt production and handling, worth preparation, fermentation, filtration, CIP and finally packag...
