Due to the low concentration of alga-lysing bacteria in an algal bloom, it is difficult to isolate the alga-lysing bacteria by existing methods. In this paper, two algae-lysing bacterial strains, P01 and P03, have been isolated from a biosystem immobilized on a sponge that was highly effective in removing algae and microcystins. Their lysing modes and effects on Microcystis aeruginosa have been studied. The results show that the degradation processes of these two strains for M. aeruginosa accorded with a first-order reaction model when the chlorophylla concentration was in the range from 0 to 1000 μgL-1. The degradation rate constants were 0.1067, 0.1274 and 0.2792 for P01 and0.0683, 0.0744 and 0.028 97 for P03, when the bacterial densities were 8.6 × 105, 8.6 × 106 and 8.6 × 107cells mL-1 respectively. Moreover, the two bacterial strains had favourable lytic effects not only on M. aeruginosa , but also on Chlorella and Scene-desmus. Their lytic effect on M. aeruginosa did not require physical cell to cell contact, but proceeded by the production of an extracellular product. The bacterial strains were identified as Bacillus species by PCR amplification of the 16S rRNA gene, BLAST analysis, and comparison with sequences in the GenBank nucleotide database.展开更多

The House of Earth Trilogy used as a window to understand China for the westerners at that time. And it had a great impact on the whole world. People gave two different views on her success of winning so many awards. Some thought that she wrote what she knew and her works were based on her own experiences. But others said that she was a foreigner and her values, her distinct aesthetic views would affect her writing. So, some of her depictions, to some extent, were untruthful and distorted. The aim of writing this thesis is to give an objective judgment on the Good Earth, and make it easier for us to communicate with the westerners on literature.展开更多

It possesses special attribute in sociology and disaster science. In accordance with human activities, geomorphologic location, behavior and particular, the man-induced sediment disaster can be divided into 4 types: the drainage network, slope and gully, channel and plain-estuary-coastline. Each type includes erosion, transportation, accumulation, complexity and cascading. Based on human activity, geomorphology, sediment mechanics and catastrophology, the man-induced sediment disaster is characterized as follows: (1) accelerating tendency with geographical zoning back-ground; (2) non-order characters by blind action without special technical training; (3) gradually and sharply changing with human environment vibration; and (4) complexity and non-linear figure, etc. One of the reasons leading to man-induced sediment disaster is human environment vibration.展开更多

The origins of enhancement and improvement are discussed. Probably the distortion and the defect of crystals are decreased by the substitution of Gd^3+ for Y^3+ instead of Eu^3+ for Y^3+ , and thus the Eu^3+ crystal field is improved, and radiationless process and energy loss resulted from crystal defect are weakened, which leads to increased luminescence intensity and voltage character improvement. The overlapping fluorescent spectra of Y2O2S: Sm^3+ emission and Y2O2S:Eu^3+ excitation as well as Eu^3 + excitation spectra transitions spectra lead to energy transfer from Sm^3 + sensitization of Sm^3+ ions fectively. containing Sm^3+ excitation the possibility of resonance ions to Eu^3+ ions, and the to Eu^3+ ions is achieved effectively.展开更多

The objective is to study the influence of the addition of bamboo fibers on the thermophysical properties of the material, while verifying that it complies with the mechanical standards in Cameroon. A double study is therefore carried out: a mechanical characterization whose objective is to determine the mechanical properties (compressive strength, flexural strength and Young’s modulus) and a thermophysical characterization whose objective is to determine the thermal conductivity. For the thermophysical characterization, the asymmetric hot plane experimental setup based on 1D quadrupole modelling was developed and simulated for the estimation of thermal effusivity E and volume heat capacity ρCp. The obtained experimental results show that the apparent thermal conductivity of the developed materials decreases with increasing fibers. Although the reference material (0% fibers) has a much higher conductivity than the ordinary sand block (1.15 Wm<sup>-1</sup> K<sup>-1</sup>), the addition of fibers, already at 2%, contributes to decrease this conductivity (0.95 Wm<sup>-1</sup> K<sup>-1</sup>). From the point of view of thermal insulation and energy savings, the thermal conductivity results obtained show that the use of these materials with a maximum fibercontent of 6% would be a better thermal insulator than sand block or compressed earth brick. The compressive strength obtained is such that Rc > 0.6 MPa. All the materials developed meet the design standards when used as infill.展开更多

The association with neurologic manifestations is very uncommon especially in patient with no immunologic defects and in cases without specific treatment. A 7 years old male patient, without any immunocromised defect, presented an atypic presentation of the cat scratch disease. The patient came to the hospital in two opportunities in a status epilepticus, in both cases the diagnosis was encephalitis by Bartonella henselae and the evolution with treatment was monitored with PCR(polymerase chain reaction) in cerebrospinal fluid and blood, as well as IFI(IgM, IgG) serology(indirect immunofluorescence). The patient had a favorable clinical and laboratory evolution for 6 months showing no recurrence of the disease.展开更多

Although the reference material (0% fibers) has a much higher conductivity than the ordinary sand block (1.15 Wm<sup>-1</sup> K<sup>-1</sup>), the addition of fibers, already at 2%, contributes to decrease this conductivity (0.95 Wm<sup>-1</sup> K<sup>-1</sup>). From the point of view of thermal insulation and energy savings, the thermal conductivity results obtained show that the use of these materials with a maximum fibercontent of 6% would be a better thermal insulator than sand block or compressed earth brick. The compressive strength obtained is such that Rc > 0.6 MPa. All the materials developed meet the design standards when used as infill.

文摘The Changjiang(Yangtze)River estuary has been subject to a variety of anthropogenic pressures in recent decades.To assess the ecological health of the coastal benthic ecosystem adjacent to the estuary,three surveys were conducted in 2005,2009,and 2010.The AZTI's Marine Biotic Index(AMBI)and multivariate-AMBI(M-AMBI)were used to analyse the benthic ecological status of this coast.The AMBI indicate that the ecological status of the coast adjacent to the Changjiang River estuary was only slightly degraded in all 3 years.In contrast,the M-AMBI indicated that the ecological status was seriously degraded,a result that is most likely due to pollution and eutrophication induced by human activities.The assessment of the coast's ecological status by the AMBI was not in agreement with that of the M-AMBI at some stations because of lower biodiversity values at those sites.The analysis of the two indices integrated with abiotic parameters showed that the M-AMBI could be used as a suitable bio-indicator index to assess the benthic ecological status of the coast adjacent to the Changjiang River estuary.The reference conditions proposed for the coast of the Changjiang River estuary should be further evaluated in future studies.Designation of local species could also provide an important reference for Chinese waters.To improve the reliability of AMBI and M-AMBI,further research into the ecology of local species is required to understand their arrangement in ecological groups.

文摘Cat scratch's disease caused by Bartonella henselae, is known to be a self-limited benign process in immunocompetent children. The association with neurologic manifestations is very uncommon especially in patient with no immunologic defects and in cases without specific treatment. A 7 years old male patient, without any immunocromised defect, presented an atypic presentation of the cat scratch disease. The patient came to the hospital in two opportunities in a status epilepticus, in both cases the diagnosis was encephalitis by Bartonella henselae and the evolution with treatment was monitored with PCR(polymerase chain reaction) in cerebrospinal fluid and blood, as well as IFI(IgM, IgG) serology(indirect immunofluorescence). The patient had a favorable clinical and laboratory evolution for 6 months showing no recurrence of the disease.

文摘Growth and nutritional status are important issues in paediatric inflammatory bowel disease(IBD).While linear growth is easy to assess,nutritional status is more complicated,with reports often compromised by the use of simple measures,such as weight and the body mass index,to assess nutritional status rather than more appropriate and sophisticated techniques to measure body composition.This review is an update on what is currently known about nutritional status as determined by body composition in paediatric IBD.Further,this review will focus on the impact of biologics on growth in paediatric IBD.Significant lean mass deficits have been reported in children with IBD compared with controls,and there is evidence these deficits persist over time.Furthermore,data imply that gender differences exist in body composition,both at diagnosis and in response to treatment.With respect to growth improvements following treatment with biologics,there are conflicting data.While some studies report enhancement of growth,others do not.The relationship between disease severity,impaired growth and the requirement for biologics needs to be considered when interpreting these data.However,key features associated with improvements in growth appear to be successful clinical response to treatment,patients in early stages of puberty,and the presence of growth failure at the onset of treatment.
