Effects of Light Intensity on Growth, Development and Formation on Fagopyrum cymosum

Effects of light intensity on growth, development and formation on Fagopy- rum cymosum were explored with natural light intensities at 100%（A）, 85.2%（B）, 75.8%（C） and 59.7%（D）. The results showed that the decline of light intensity re- duced nutrient growth period, so that plant growth stage entered in advance and extended, which indicated that the decline of light intensity would lower leaf number and area, the number of twigs from the stem, as well as photosynthate. Further- more, the reduction degree increased upon light intensity decrease degree, and the proper shading improved stem height and leaf area enhanced before growth term.

Effects of light intensity on activity in four sympatric anuran tadpoles

Though light conditions are known to affect the development and anti-predation strategies of several aquatic species, relatively little is known about how different species react to light, or how light can affect these species during different points in their life-cycle. In this study, we used four sympatric anuran tadpoles （Bufo gargarizans, B. melanostictus, Pelophylax nigromaculatus and Microhyla fissipes） as animal system to examine species-specific activities of the underdoing different light intensity treatments, so as to better understand how they respond to light. We exposed four different species of tadpoles to 1660 and 14 lux light intensity treatments and then measured several parameters including development stage, body length and tail length, and as well as their basic activities. The results of this observation and analysis showed that the activities of tadpoles were significantly greater in B. gargarizans and B. melanostictus than in P. nigromaculatus and M. fissipes; and were also significantly greater during times of high light intensity as compared to during low light intensity. Moreover, the observed relationship between species and light intensity was significant. The activities ofB. gargarizans and B. melanostictus tadpoles were greater in high light, while the activity of P. nigromaculatus tadpoles was greater in low light intensity, while M. fissipes tadpoles showed no differences in either low or high intensity light. Furthermore, the activities orB. gargarizans, B. melanostictus and M. fissipes tadpoles in terms of developmental stage, body size or tail length did not seem to differ with light intensity, but during early larval developmental period of P. nigromaculatus, the activity of tadpoles was negatively correlated with development stage, but irrelevant to either body size or tail length in different light intensities. These results lead us to conclude the observed activities of the four sympatric anuran tadpoles are closely correlated with their specific anti-predation strategies.

Islam and Girls＇ Education： Obligatory or Forbidden

＂Acquisition of knowledge is binding on all Muslims＂ （al-Sunan 1：81 ~224）. This Hadith, sayings or actions of the prophet Muhammad （MPBUH）l, indicates that there is no preference based on sex in getting access to education in Islam; however, there is a growing misconception among the people of other religions that Islam constrains Muslim girls from getting education. This paper reviews literature and two authentic sources of Islamic scriptures, which are the Holy Qura＇an and the Ahadith to position the girls＇ education in purview of Islam. It further examines the possible reasons for conflicting interpretations of Islamic teachings. It concludes that Islam does not restrict girls from getting education. It recommends further systematic studies for exploring the reasons for the projection of distorted images of Islam.

Effects of spectral composition,photoperiod and light intensity on the gonadal development of Atlantic salmon Salmo salar in recirculating aquaculture systems(RAS)

Artificial lighting regimes have been successfully used to inhibit sexual maturity of Atlantic salmon in confinement.However,when these operations are applied in commercial recirculating aquaculture systems(RAS) using standard lighting technology,sexual maturation is not suppressed.In this study,an L_9(3~3) orthogonal design was used to determine the effects of three factors(spectral composition,photoperiod,and light intensity) on the gonadal development of Atlantic salmon in RAS.We demonstrated that the photoperiod at the tested levels had a much greater effect on the gonadosomatic index and female Fulton condition factor than spectral composition and light intensity.The photoperiod had a significant effect on the secretion of sex steroids and melatonin(P<0.05),and a short photoperiod delayed sex steroid and melatonin level increases.The three test factors had no significant effects on the survival rate,specific growth rate,relative weight gain,and male Fulton condition factor(P>0.05).The optimum lighting levels in female and male Atlantic salmon were LD 8:16,455 nm(or 625 nm),8.60 W/m^2;and LD 8:16,8.60 W/m^2,455 nm respectively.These conditions not only delayed gonadal development,but also had no negative effects on Atlantic salmon growth in RAS.These results demonstrate that a combination of spectral composition,photoperiod and light intensity is effective at delaying the gonadal development of both male and female salmon in RAS.

Moderating variables in the relationship between mental toughness and performance in basketball

Purpose： This study explored the relationship between mental toughness and college basketball performance, specifically examining possible moderating variables （gender and starting status）. Methods： Male and female （n = 197） college basketball players completed the Psychological Performance Inventory-Alternative （PPI-A）, a measure of characteristics and skills consistent with mental toughness, and the PERK an objective measure of basketball performance. Results： Findings suggest that basketball performance can be partially predicted by mental toughness and starting status. Males reported greater mental toughness than females. Starters and nonstarters did not differ in mental toughness. Moderated hierarchical regression analysis indicated that mental toughness was related to performance for male players as both a main effect and interaction with starter status. For female players, in contrast, starter status was the only significant predictor of performance. Practitioners are encouraged to foster the psychological skills associated with mental toughness in females and non-starters in basketball. Conclusion： Discussion of the PPI-A as a measure of mental toughness and suggestions for its improvement are explored. A need exists for additional research on mental toughness and objective performance, as performance enhancement is a major impetus for research on mental toughness.

Effective measures to study the future development of social sports

Community sports mean the workers, farmers, and other residents of the street, voluntarily participate diverse content-rich forms of mass sports activities in order to promote good health in their leisure time. Social Sports are a fundamental part of the mass sports in China, it has entirely voluntary amateur principle distinct from a high level of competitive sports, but also different from school sports and military sports with certain mandatory ingredients.

Implications of exergaming for the physical education curriculum in the 21st century

Exergaming provides an initial situationally interesting environment in physical education （PE） that serves to motivate novice players to engage in PE or physical activity. Current research suggests, however, that as students persist in this activity their situational interest decreases as their ability to exercise consistently at moderate intensity levels increases. In this article I will briefly review the literature citing benefits of exergaming and the role of exergaming in contemporary PE curricula before turning to the question of the place of exergaming in a learning- oriented approach to PE. I will suggest that exergaming, when taught within a situated learning framework, can contribute to student under- standing of the effects of exercise on their bodies and may produce meaningful lessons to assist students to create, monitor, and adapt a fitness plan to participate in life long exercise using a variety of physical activities.

Examining the Impacts of China＇s Aging Population on Its Labor Suppl.y from the Labor Quality Perspective

On the basis of sufficient considerations to the attributes of China＇s development and uniqueness of population aging, this paper examines the overall impacts of China＇s population aging on labor supply in the four aspects of education level, skill level, work intensi（y and the share of working age population. Results indicate that despite the irreversibil#y in the decline of labor supply under the effect of intensifying degrees of population aging in the long run, this tendency will be weakened or slowed down by the improvement in labor quali^y. It is expected that China＇s real labor supply will not encounter a significant turning point by 2027, which is 12 years later than the occurrence of decline in nominal labor supply measured by labor quanti~

Exploring the relationship of physical exercise situations, attitude and intensity with middle school students＇ shame

TinII intron, an enhancer to affect the function of the cytoplasmic male sterility related gene T in Brassica juncea

The T gene, which was cloned from the mitochondria of tumorous stem mustard （Brassica juncea var. tumida）, is a cytoplas- mic male sterility （CMS）-related gene that can produce two transcripts, T1170 and T1243. The latter is transcribed with the un- cleaved intron Tinll. In our previous study, transgenic Arabidopsis thaliana plants over-expressing the T1243 transcript （OE-T1243） showed a severe male-sterile phenotype, whereas OE-Tll70 plants did not. However, the functional mechanism of the T gene in B. Juncea remained unknown. In this study, microscopic analyses of paraffin sections of anthers confirmed that OE-T1243 plants did not produce normal pollen, whereas OE-T1170 plants did. We analyzed the transcription of 15 anther development-related genes and found that transcript levels of nozzle/sporocyteless and barely any meristem 1 and 2 were markedly lower in OE-T1243 plants than those in wild type, while the transcript levels of these genes in OE-Tll70 plants were unchanged. To investigate the potential roles of TinH, we inserted the TinH sequence upstream of a minimal region （-60） of the cauliflower mosaic virus 35S promoter fused to the 5＇ end of the 13-glucuronidase （GUS） reporter gene. Analysis of the transgenic plants suggested that TinH acted as an enhancer to significantly increase GUS expression. The potential action mechanism is that the TinH intron acts as an enhancer to affect the function of the CMS-related gene T.
