In nuclear power plants, the main corrosion product that is deposited on the outside of steam generator tubes is porous magnetite. The objective of this study was to simulate porous magnetite that is deposited on thermally treated (TT) Alloy 690 steam generator tubes. A magnetite layer was electrodeposited on an Alloy 690TT substrate in an Fe(III)-triethanolamine solution. After electrodepositi...

In this paper, we present a real-time image processing technique for the detection of steam in video images. The assumption made is that the presence of steam acts as a blurring process, which changes the local texture pattern of an image while reducing the amount of details. The problem of detecting steam is treated as a supervised pattern recognition problem. A statistical hidden Markov tree ...

Five blocks of farmer’s sugarcane fields were selected in district Jalandhar, Punjab during December 2016 to February 2017. These treated with 2% zinc phosphide (ZnP), ZnP+ 0.005% bromadiolone (Br), 0.25% triptolide (Tr) and Br+ Tr at cane maturation stage; 5th block was kept as untreated control. The post census % re-buildup rodents after 30 45 days treatment cut canes (%) significantly less r...

A number of methods are presented to treat sewage sludge. However, the sludge treated in each treatment process has a problem of heavy metal elution. Currently, the treatment of sewage sludge through carbonization is highlighted to solve such problem. This study carried out research of optimum carbonization and activation condition and analysis of adsorption characteristics in order to treat se...

Sugarcane (Saccharum spp.) is grown on over 8 million ha in Brazil and is used to produce ethanol and sugar. Some sugarcane fields are burned to facilitate harvesting, which can affect the soil microbial community. However, whether sugarcane pre-harvest burning affects the community of arbuscular mycorrhizal fungi (AMF) and symbioses development is not known. In this study, we investigated the ...

The current nitrogen fertilization for sugarcane production in Guangxi, the major sugarcane-producing area in China, is very high. We aim to reduce nitrogen fertilization and improve sugarcane production in Guangxi with the help of indigenous sugarcane-associated nitrogen-fixing bacteria. We initially obtained 196 fast-growing bacterial isolates associated with the main sugarcane cultivar ROC22...

Knowledge about gene expression during sugarcane growth and maturation is limited. A gene discovery programme has been in progress at SASEX since 1994 to identify and analyse genes that are expressed in different sugarcane tissue types and developmental stages. A database of sugarcane gene sequences has been established through the generation of Expressed Sequence Tags (ESTs). This database, co...

The emissions from simulated sugarcane (Saccharum officinarum) field burns were sampled and analyzed for polychlorinated dibenzodioxins and dibenzofurans (PCDDs and PCDFs). Sugarcane leaves from Hawaii and Florida were burned in a manner simulating the natural physical dimensions and biomass density found during the practice of preharvest field burning. Eight composite burn tests consisting of ...

Cry1Ac transgenic sugarcane provides a promising way to control stem-borer pests. Biosafety assessment of soil ecosystem for cry1Ac transgenic sugarcane is urgently needed because of the important role of soil microorganisms in nutrient transformations and element cycling, however little is known. This study aimed to explore the potential impact of cry1Ac transgenic sugarcane on rhizosphere soi...

Population structure determines sugarcane yield, of which canopy structure is a key component. To fully understand the relations between sugarcane yield and parameters of the canopy structure, 17 sugarcane varieties were investigated at five growth stages. The results indicated that there were significant differences between characterized parameters among sugarcane populations at different grow...
