Authors: Sun Xiang Yang , Liu Xiao Bing , Gao Cheng Da
Published: August 2014

Carbon dioxide plays important role in various spheres of the Earth system (lithosphere, soil, hydrosphere, atmosphere and biosphere) for material of storage, transformation, transfer and interaction. In the research, two approached to measure CO2flux at soil surface and in profiles was carried out in situ in arid area. The background CO2concentration was 323.49 ± 21.36 × 10-6(volume fraction) in the surface of the atmosphere, and there are seasonal and diurnal change in the carbon dioxide concentration. For CO2flux between soil and atmosphere, the average CO2flux was 230.05 μmol·m-2·h-1 from the four kind soils, and CO2flux exhibited seasonal and diurnal variations too. For CO2flux from soil (the chestnut soil, sierozem soil, fragmental soil, and gray-cinnamon soil) that was exposed to air, CO2flux increased when soil from 0–60 cm depth was exposed but decreased when soil at 61–70 cm depth was exposed. The results show that 1) vegetation characteristics and temperature greatly affect CO2concentrationat the soil surface; 2) CO2may be released from the soil into the atmosphere at 254.6 t·km-2·yr-1if the soil at 0–70 cm depth is exposed to the air because of a change in land use or land cover; 3) the soil may absorbed CO2when plants were not growing in northern hemisphere; 4) The differences in the distribution of heat energy on the Earth's surface indicate a mechanism by which soil can regulate the concentration of CO2in the atmosphere of temperate-arid regions in northern hemisphere.

Published: August 2014

Bio-drying process, degrading part of the easily biodegradable organic fraction contained in waste, produces heat that combined with an adequate airflow-rate, allows the fast evaporation of waste moisture content. Three ventilation methods were used to investigate the effect of bio-drying pretreatment on municipal solid waste (MSW) characteristics (including water content, mass, heating value and the gross energy capacity). The results show that the water content of MSW decreased from 61.5% to minimum 23.7% after 18 days bio-drying, whereas its lower heating value (LHV) increased an average of 168% from 5413 kJ/kg. In the three trials, the highest LHV amounted to 15.8 MJ/kg, which achieved the LHV demand of solid recovery fuel (SRF). In bio-drying process, the average water removal rate was 80.6%. Smaller organic matter degradation led to a great decline of the water content; therefore, the decrease of gross energy capacity of MSW is not significant.

Authors: Li Xiu Di , Cao Jun Xi
Published: August 2014

The responses of ground-wandering spider communities were examined in terms of species composition, population structure and population diversity in subtropical, hill-country tea plantations subjected to two contrasting systems of agricultural management. Samples were collected between June 2010 and May 2011 from tea plantations using either low-carbon intercropping management (plantation JZ) or routine management (plantation CK), using both clapping and trapping methods of sample collection. The results showed that the composition of the spider community in plantation JZ was significantly richer, on the basis of several quantitative measures, than in plantation CK (P <0.001), with 3.17 times, 1.68 times and 1.40 times the numbers of female, male and immature spiders present, respectively. In addition, in plantation JZ, in which four species of spider were predominant, the diversity index and richness index were increased, respectively, by 15.09% and 9.85%. Principal components analysis (PCA) showed that the management regime of plantation JZ was significantly reflected in the distributions of Houa jiafui, Pardosa pusiola and Venonia spirocysta, whereas that of plantation CK was reflected in the distribution of Zelotes asiaticus. Therefore, in a low-carbon management regime a rich diversity of plant species is conducive both to the reduction of CO2 emissions and to the protection of species diversity in ground-wandering spiders.

Investigation on a Novel Seawater Exhaust Gas Cleaning System Applied for SOx Emissions Reduction of Marine Diesel Engine
Authors: Wu Xiao Chun , Wang Zhong Jun
Published: August 2014

The control and regulation of SOx emissions have become a global urgent problem for the environment protection. In the field of ocean and marine engineering, The International Maritime Organization (IMO) has formally passed the amendment of MARPOL 73/78 Annex VI in 2008 that clarified the deadline of requirements on SOx emissions limit. A limitation of 3.5 %mm is strictly requested during 2012 to 2020. Hence the SOx emissions of marine diesel engines faces unprecedented challenges while effective control and regulation systems on the SOx emissions reduction are scarce in the existing ships. To meet the IMO's requirements, this paper has presented a novel seawater exhaust gas cleaning (EGC) system for the SOx emissions reduction of marine diesel engines. The post-combustion desulfurization technology was employed in the EGC system. The carbon ion and hydrogen ion contained in the seawater have been introduced into the EGC system to participant the reaction of desulfurization. The seawater EGC system has already been established in a real ship. Experiments have been carried out with the established seawater EGC system to comparatively analyze SOX emissions characteristics when burning different oil types, including heavy oil and light oil. The experiment results show that the newly established seawater EGC system can achieve satisfactory performance with a desulfurization efficiency of 88%. More important, the standard of the SOX emission limitation set by IMO has been met by using the proposed EGC system.

With the development of electrolytic aluminum in our country, sulphur content in aluminum anode increased year by year, thus there is the risk of SO2 discharge over standard in exhaust gas treatment in electrolytic aluminum industry. Further, the waste heat from exhaust gas of electrolytic aluminum has not been made full use at present. It is necessary to development new exhaust gas treatment and utilization technology. In this study, a scheme about electrolytic aluminum exhaust gas cascade utilization has been proposed according to the characteristics of electrolytic aluminum exhaust gas. The electrolytic aluminum exhaust gas after dry treatment could be sent to power plant boiler as combustion air, as the discharge of electrolytic aluminum exhaust gas and air pollutants could be decreased greatly. After the comparison of techno-economic analysis, the discharge by the scheme of cascade utilization was less than that with desulfurization, with more economic benefit. Thus it is worth to be extended, since the scheme of electrolytic aluminum exhaust gas cascade utilization showed good techno-economy.

We studied the changes of physicochemical and biological properties in order to evaluate the stability and maturity of the composting process during the forced-aeration composting process of tobacco industry wastes. Composting was carried out using two methods, i.e. waste tobacco leaves mixed with 15% waste tobacco stems (bioreactor A) and the addition of 30% waste tobacco stems (bioreactor B). The results showed that two composting all maintained the temperature exceeding 55°C for more than 3days. Compared with treatment B, the time of reach high temperature in the treatment A was shorted by 1 day and the sustaining time of high temperature extended by 3 days. The final electrical conductivity in compost A did not exceed the limit value of 3.00ms/cm-1for stable compost. The final germination index in composting A and B were 111% and 85% respectively, which suggested a higher stability in composting A than B.

It is urgent for agricultural and forestry wastes (AFWS) to be handled efficiently as the generations of them are increasing rapidly in China. The paper studied the bacterial community variations in composting of AFWS with different three microbial agents by PCR-DGGE. Three microbial agents in the research werePhanerochaete chrysosporium(PC) ,Coriolus versicolor(CV) and GP (agent developed from laboratory with high lignocellulose degradation ability). DGGE profiles indicated that the populations of bacteria reduced from warming period to high-temperature phase fistly, then increased till cooling period, and finally descended during maturity period for all the composting treatments. The populations of bacteria in composting with GP innoculation keeped on a high level during high-temperature phase, cooling period and maturity period. In the early phase of the high temperature composting, Bacillus sp., Uncultured Bacillus sp., Pseudomonas sp., Uncultured Pseudomonas sp., Micrococcus sp., Brevibacterium, Sphingomonas sp., Aminobacter aminovorans and Uncultured Acinetobacter sp.were rich, and became the dominant flora of the period. The number of the same dominant flora in AFWS composting with GP and CV innoculations was the most during the high-temperature phase. Simultaneously, the number of the same dominant flora in AFWS composting with GP and PC innoculations was the most during cooling period. Therefore, GP has a good prospect in AFWS composting process for resource utilization.

Effect of Vitamin D3 on Untreated Graves' Disease with Vitamin D Deficiency
Authors: Alhuzaim Omar N. , Aljohani Naji
Published: August 2014

Objective

Besides its classical role in calcium and bone homeostasis, vitamin D is considered a potent immunomodulator that can affect the pathogenesis of several autoimmune diseases. Our aim is to evaluate the effect of vitamin D correction to a patient with new onset Graves' disease (GD) with an underlying vitamin D deficiency.

Method

We describe the effect of vitamin D3 on untreated Graves' disease with vitamin D deficiency.

Results

A healthy Saudi woman in her 40s sought consultation with a three-month history of palpitation. She denied any history of heat intolerance, weight loss, menstrual irregularity or sweating. She has a history of chronic muscle aches and pains. Physical examination revealed a mild diffusely enlarged and non-tender thyroid gland with no bruit. She had no signs of Graves' ophthalmopathy. In laboratory examinations, the initial thyroid function test, which was done in an outside hospital, revealed a TSH, 0.01 mIU/L; FT4, 22.5 pmol/L and FT3, 6.5 pmol/L. Vitamin D 25-OH level was done in our hospital and showed a result of 26.0 nmol/L with a TSH, 0.013 mIU/L; FT4, 16.7 pmol/L; and FT3, 3.8 pmol/L. TSH receptor antibody was positive. TC-99 m thyroid scintigraphy demonstrated an enlarged thyroid gland with increased radiotracer trapping and heterogeneous distribution. The patient was given only oral cholecalciferol 4000 IU per day since November 2012 (prescribed by an outside hospital) then from May 2013 onwards she was given 50,000 IU per month. Follow-up laboratory exams revealed improved vitamin D levels as well as TSH and FT4. She eventually improved both clinically and biochemically with a satisfactory outcome.

Conclusion

Vitamin D deficiency may exacerbate the onset and/or development of GD and correction of the deficiency may be able to reverse it. However, further prospective clinical studies will be needed to define the role of vitamin D treatment in GD.

Authors: Reymond David , Dematraz Jessica
Published: August 2014

Bibliometry coupling is used to process bibliographic data to assert existing latent information on publication material. We apply here this technique on patent data gathered from the OPS web service to enhance the exploration process of patents using network visualization. The following will present briefly graph theory preliminaries, the gathering and transforming process on the ops base. The different networks produced will be discussed and placed in a generic economic intelligence process. Finally we present a case study using this approach to discuss the democratization of 3D printing.

A análise dinâmica de redes sociais é uma área ainda pouco explorada no campo da Análise de Redes Sociais, sobretudo no Brasil, trazendo a perspectiva de ampliar os estudos estruturais de rede para incorporar aspectos evolutivos e temporais de como a rede se desenvolvem. O artigo trabalha com um estudo de caso na área da Ciências da Comunicação através dos dados coletados do portal Univerciencia.org, aplicando um conjunto de 10 indicadores que serão analisados ao longo de um período de 26 anos num conjunto de 1953 documentos. O artigo mostra como a rede se desenvolve de forma fragmentada e dependente da ação de grupos locais ainda desarticulados entre si.
How Might a Central Bank Report Uncertainty?
Authors: Fair Ray C.
Published: August 2014

An important question for central banks is how they should report the uncertainty of their forecasts. This paper discusses a way in which a central bank could report the uncertainty of its forecasts in a world in which it used a single macroeconometric model to make its forecasts and guide its policies. Suggestions are then made as to what might be feasible for a central bank to report given that it is unlikely to be willing to commit to a single model. A particular model is used as an illustration.
Planarians as invertebrate bioindicators in freshwater environmental quality: the biomarkers approach
Authors: Knakievicz Tanise
Published: August 2014

Environmental contamination has become an increasing global problem. Different scientific strategies have been developed inÂ order to assess the impact of pollutants on aquatic ecosystems. Planarians are simple organisms with incredible regenerativeÂ capacity due to the presence of neoblastos, which are stem cells. They are easy test organisms and inexpensive to growÂ in the laboratory. These characteristics make planarians suitable model-organisms for studies in various fields, includingÂ ecotoxicology. This article presents an overview of biological responses measured in planarians. Nine biological responsesÂ measured in planarians were reviewed: 1) histo-cytopathological alterations in planarians; 2) Mobility or behavioral assay;Â 3) regeneration assay; 4) comet assay; 5) micronucleus assay; 6) chromosome aberration assay; 7) biomarkers in molecularÂ level; 8) sexual reproduction assay; 9) asexual reproduction assay. This review also summarizes the results of ecotoxicologicalÂ evaluations performed in planarians with metals in different parts of the world. All these measurement possibilities makeÂ Planarians good bioindicators. Due to this, planarians have been used to evaluate the toxic, cytotoxic, genotoxic, mutagenic,Â and teratogenic effects of metals, and also to evaluate the activity of anti-oxidant enzymes. Planarians are also consideredÂ excellent model organisms for the study of developmental biology and cell differentiation process of stem cells. Therefore, weÂ conclude that these data contributes to the future establishment of standardized methods in tropical planarians with basis onÂ internationally agreed protocols on biomarker-based monitoring programmes.

Published: August 2014

In this study the effect of probiotic preparations and plant extract was investigated against eleven fish bacterial pathogens viz. Aeromonas hydrophila, Cellobiococcus sp., Enterobacter aerogenes, E. cloacae, Klebsiella pneumoniae, Salmonella sp., Shigella sp., Streptobacillus sp., Streptococcus sp., Pseudomonas fluorescens and Staphylococcus aureus. All these pathogens were found to be resistant for antibiotics viz. nitrofurantoin, amoxycillin, bacitracin, cephalothin, erythromycin, novobiocin, vancomycin , amphicillin, oxacillin and colistin. In vitro antagonism test of the probiotics was performed by using well diffusion method. In case of probiotic AquaproTM, effective zone of inhibition of 2.433 cm was observed for P. fluorescens and K. pneumoniae. The extracts of Azadirachta indica, Aloe barbadensis, Withania somnifera and Momordica charantia were studied in vitro alone as well as in combination with probiotic (Lactobacillus sporogenes). The zone of inhibition observed in mixed sample was less as compared to individual sample. Among the four plants extract, the W. somnifera extract was found to be the most effective and it leads to maximum inhibition (1.1 cm) recorded for E. aerogenes.

Some factors may contribute to potentiate the toxicity effects of soil contaminants on the organisms, among them is the acidification process derived from acid rain. Thus, the aim of this study was to assess the toxicity of a soil under the influence of an industrial complex through exposure of Swiss mice to soil leachates in different pH values . Soil samples were collected in Rio Grande, Brazil. At the laboratory, Swiss male mice were exposed by gavage (single dose) to soil extracts with different pH values (7.0, 5.2 and 3.6). The results showed toxic effects related to the decrease in pH and to increase in the concentration of soil extract. Therefore, the results showed that acid rain simulating solutions are able to potentiate the toxicity of the soil contaminants, and these conditions must be taken into account to environmental diagnosis in cities with occurrence of acid rain such as Rio Grande.
