English as an academic lingua franca, many possibly negative effects of the widespread use of English at universities have been discussed, e.g., the potential disappearance of local languages, the lowering of learning standards, or the linguistic  ( ) in the domain of international publication where English is the dominant language.

1 Polylactide (PLA) has received much attention in recent years due to its biodegradable properties, which offer important economic benefits

2 PLA is a polymer obtained from corn and is produced by the polymerisation of lactide、

3 It has many possible uses in the biomedical field1 and has also been investigated as a potential engineering material[2,3]、4 However, it has been found to be too weak under impact to be used commercially[4]

5 One way to toughen polymers is to incorporate a layer of rubber particles [5] and there has been extensive research regarding the rubber modification of PLA

6 For example, Penney et al、showed that PLA composites could be prepared using blending techniques [6] and more recently, Hillier established the toughness of such composites[7]

7 However, although the effect of the rubber particles on the mechanical properties of copolymer systems was demonstrated over two years ago [8], little attention has been paid to the selection of an appropriate rubber component、

8 The present paper presents a set of criteria for selecting such a component

9 On the basis of these criteria it then describes the preparation of a set of polymer blends using PLA and a hydro-carbon rubber(PI)

10 This combination of two mechanistically distinct polymerisations formed a novel copolymer in which the incorporation of PI significantly increased flexibility

2) The results of the performances mean that the anammox culture in our reactor could hydrolyze urea and produce ammonium,which was then used with nitrite for anammox to carry out the Anammox reaction.

3) The phenomena in phase III might be due to the increase of urease hydrolyzing urea, and it requires further study.

4) The change of the three kinds of nitrogen charge was approximately consistent with the Anammox stoichiometry, demonstrating the Anammox reaction has taken place well in phase I.

5) According to the reports by Sliekers et al.(2004), the Anammox bacteria in their study were not able to hydrolyze urea, and a question whether or not other kinds of Anammox bacteria are capable of hydrolyzing urea exist was raised.However, in phase II, although ammonium concentration was hardly measured, the urea removal was increased all the time.

6) As a result of the possible existing of other bacteria in Anammox culture, the conclusion that Anammox can hydrolyze urea could not be obtained by the above experiments.

2 In our study, modelled emission rates were obtained using the Traffic Emission Model (TEM), a CO-exposure modelling framework developed by Ka.[3] Modelled results were compared with actual roadside CO concentrations measured hourly at a fixed monitor.

3 Figure 1 shows the results obtained using TEM.

4 As can be seen, during morning peak-time journeys the CO concentrations for car passengers were significantly lower than for pedestrians, which is consistent with results obtained in previous studies.[2]

5 However, the modelled data were not consistent with these results for afternoon journeys.

6 Although the mean CO concentrations modelled by TEM for afternoon journeys on foot were in line with those of Figo et al., a striking difference was noted when each of the three peak hours was considered singly (Fig.2).

7 It can be observed that during the first hour (H1) of the peak period, journeys on foot resulted in a considerably lower level of CO exposure.Although levels for journeys on foot generally exceeded those modelled for car journeys during H2, during the last hour (H3) the levels for journeys on foot were again frequently far lower than for car journeys.      

8 A quantitative analysis to determine modelling uncertainties was applied, based on the maximum deviation of the measured and calculated levels within the considered period.

9 Using this approach, the average uncertainty of the model prediction for this study slightly exceeds the 50% acceptability limit defined by Jiang.[7]

10 Nevertheless, these results suggest that data obtained using TEM to simulate CO exposures may provide more sensitive information for assessing the impact of traffic management strategies than traditional on-site measurement.

2) Future experimental work should expand the range of test conditions, including more complete data with different parameter values for excitation 

3) Try using higher temperatures at atmospheric pressure to see what happens. 

4) The graphene sample thickness is not consistent. 

5) In future we plan to add other metrics such as load in our analysis. 

6) The scope of this study did not permit us to examine positioning subsystem 

7) It is hoped that this research can serve as a basis for future studies into generalized Steinmetz equation. 

8) These results are preliminary findings and suggest that further research on the Steinmetz parameters.

9) Given this limitation, we do not know if/whether the Kalman filter may minimize the negative effect of noise and measurement error. 

10) Finally, our results say little about exposure “quality”.

2 However, these studies have either been short-term studies or have not focused on patients whose disorder was stress-related.

3 In this study we tested the extent to which an extended three-month stress management programme improved QoL among a group of patients being treated for stress-related skin disorders such as eczema.   

4 We found that in virtually all cases, participation in our three-month stress management programme was associated with substantial increases in the skills needed to improve QoL.

5 These findings extend those of Kaliom, confirming that a longer, more intensive period of stress-management training tends to produce more effective skills than when those skills are input over a shorter period via information transfer media such as leaflets and presentations (Kaliom et al., 2003).

6 In addition, the improvements noted in our study were unrelated to age, gender or ethnic background.

7 This study therefore indicates that the benefits gained from stress-management intervention may address QoL needs across a wide range of patients.   

8 Most notably, this is the first study to our knowledge to investigate the effectiveness of extended psychosocial intervention in patients whose disorder is itself thought to be stress-related.

9 Our results provide compelling evidence for long-term involvement with such patients and suggest that this approach appears to be effective in counteracting stress that may exacerbate the disorder.

10 However, some limitations are worth noting.Although our hypotheses were supported statistically, the sample was not reassessed once the programme was over.

11 Future work should therefore include follow-up work designed to evaluate whether the skills are retained in the long term and also whether they continue to be used to improve QoL.
