Study on photodegradation of Azo dye by polyoxometalates/polyvinyl alcohol

A series of photocatalysts, K11[Ln(PW11O39)2]/PVA (Ln=La, Ce, Pr, Nd, Sm) were prepared by K11[Ln(PW11O39)2] (Ln=La, Ce, Pr,Nd, Sm) containing five kinds of lanthanides and polyvinyl alcohol as the support. The catalysts obtained were characterized by Fourier trans-form infrared spectra, UV-vis spectra, powder X-ray diffraction, and scanning electron microscopy, indicating that the structure of K11[Ln(PW11O39)2] and polyvinyl alcohol remained intact, respectively. The photocatalysts exhibited efficient catalytic activity to degrade methyl orange, Congo Red, Ponceau 2R. The maximal degradation conversions of the three kinds of dyes were 99.58%, 47.61%, 72.42%, respectively.

铅市分析

11月份以来,LME三个期铅价基本上单边下行,跌至近1150美元,接近10月下旬低点。后市走向,初步分析如下:利空因素:宏观经济陷入收缩或衰退,对铅消费影响最大的汽车行业,同样面临危机。铅消费需求毫无疑问已处于衰减之中。供应来看,一是冶炼厂,中国10月份同比增产21.17%,且从本公司铅精矿进口贸易来看,原料供应充足,因此,近期大量减产的可能性不大。二是近期库存,LME库存持续减少,目前仅4万吨多点,但中国有大量商业库存,且LME库存低的主要原因也是中国出口近零水平所致。

Longitudinal relationships of levels of language in writing and between writing and reading in grades 1 to 7.

Longitudinal structural equation modeling was used to evaluate longitudinal relationships across adjacent grade levels 1 to 7 for levels of language in writing (Model 1, subword letter writing, word spelling, and text composing) or writing and reading (Model 2, subword letter writing and word spelling and reading; Model 3, word spelling and reading and text composing and comprehending). Significant longitudinal relationships were observed within and across levels of language: spelling to spelling and spelling to composing (Grades 1 to 7), Models 1 and 3, and composing to spelling (Grades 3 to 6, Model 1; Grades 4 to 6, Model 3); spelling to word reading and word reading to spelling (Grades 2 to 7), Models 2 and 3; spelling to word reading (Grade 1), Model 2, and word reading to spelling (Grade 1), Model 3; composition to comprehension (Grades 3 to 5), Model 3; comprehension to composition (Grades 2 to 6), Model 3; and comprehension to word reading (Grades 1 to 6), Model 3. Results are discussed in reference to the levels of language in translating ideas into written language and integrating writing and reading.

Emotions in memories of success and failure: A cultural perspective.

Americans and Chinese tend to behave differently in response to success and failure: Americans tend to persist on a task after success, whereas Chinese tend to persist after failure. This study examined whether cultural differences in emotional reactions to success and failure account for these differences. American and Chinese students recalled personal success and failure events, evaluated the primary emotion evoked by the event, and responded to measures of concerns, appraisals, and willingness to try the same task again. Americans were more likely than Chinese to report that their success enhanced their self-esteem. Chinese were more likely than Americans to estimate that their success would make others jealous and enhance others' respect for their family. Chinese, compared to Americans, viewed failures as more tolerable, as less problematic for their goals, and as less damaging to their self-esteem. Culture moderated the relations between these components of emotion and willingness to try the task again. In short, culturally framed emotional reactions to success and failure result in different patterns of anticipated self-regulation. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

The relevance of Aristotle’s conception of eudaimonia for the psychological study of happiness.

According to the ethical system of eudaimonism, a philosophy that predates Aristotle, individuals have a responsibility to recognize and live in accordance with their daimon or "true self." The daimon refers to the potentialities of each person, the realization of which represents the greatest fulfillment in living of which each is capable. The daimon is an ideal in the sense of being an excellence, a perfection toward which one strives and, hence, it can give meaning and direction to one's life. Eudaimonia, then, is activity in accordance with one's daimon. This is what is considered worth having in life. Since Aristotle in the Nicomachean Ethics is concerned with the proper ends of human functioning, he rejects the view of eudaimonia as a subjective state equivalent to, or similar to, hedonic enjoyment. But if psychologists are to be able to make productive use of the Aristotle's conception of eudaimonia, it must be rendered in a form more congenial to the field. In pursuing this goal, I have found it necessary to take several significant departures from the Aristotelian perspective, while I have endeavored to remain true to Aristotle's ethical objectives. The most important of these departures is to consider eudaimonia to have a subjective component embodying the experiences that flow from efforts to live in truth to one's daimon by striving to develop one's aptitudes and talents for purposes deemed worth having in life.

Numerical analysis of effect of the solutes on formation of MnS in non-tempered steel

To analyse the effects of solute elements on formation of MnS in the micro-alloyed non-tempered steel, a novel coupling model of micro-segregation and MnS precipitation during solidification was built using the finite-difference method. Non-tempered 49MnVS3 steel was used to detect the effects of concentrations of elements on the precipitation behaviour of MnS. The results show that with contents of Mn at 0.05～2%, S at 0.001～0.3%, Si at 0.3～0.7%, P at 0.001～0.05%, C at 0.05～1.0%, the precipitation temperature of MnS raised from 1360 to 1432°C, 1397 to 1447°C, 1425 to 1418°C, 1425 to 1418°C, dropped from 1488 to 1358°C, and its precipitation solidification ratio dropped from 1 to 0.785, 1 to 0.51, 0.883 to 0.866, 0.88 to 0.86, 0.96 to 0.77, respectively; the observed temperature of MnS by HT-SM was 1427.2°C, close to the calculated temperature of 1420.6°C by the proposed the diffusion control growth model.     

The infernal now: Linking temporal inefficacy to cognitive ability and social adjustment.

In three studies with younger and older adults, we examined the correlates of temporal inefficacy (TI), that is, discontent with the uncontrollability of the passage of time experienced as linear. Among young adults, high versus low TI was related to greater subjective salience of the present, but guided focus on either conception or death eliminated this relationship. Among older adults, higher TI was inversely related both to the capacity to engage in mental time travel—as assessed by an autobiographical recall task, suggesting that the salience of the present associated with TI reflects chronic difficulty in accessing past and future—and to working memory capacity, illustrating the pivotal role of cognitive resources in effective coping among older adults. Reflecting the perceived lack of control inherent to TI, higher TI was linked to compensatory efforts to reassert personal control in other domains—specifically, a heightened tendency to personalize and overattribute meaning to random events, a greater expressed willingness to subordinate a spouse's well-being to one's own, and a callous, manipulative attitude toward other people in general. Finally, TI was inversely related to age, suggesting that maturation may include reconciling oneself to the existential limits imposed by linear time.

Verbal deception from late childhood to middle adolescence and its relation to executive functioning skills.

The present investigation examined 8- to 16-year-olds' tendency to lie, the sophistication of their lies, and related cognitive factors. Participants were left alone and asked not to look at the answers to a test, but the majority peeked. The researcher then asked a series of questions to examine whether the participants would lie about their cheating and, if they did lie, evaluate the sophistication of their lies. Additionally, participants completed measures of working memory, inhibitory control, and planning skills. Results revealed that the sophistication of 8- to 16-year-olds' lies, but not their decision to lie, was significantly related to executive functioning skills.
