However, the high cost of commercial culture medium is one of the challenges to microalgal production. Therefore, it is essential to find an alternative cost-effective culture medium. Aquaculture wastewater is considered as a highly potential candidate due to its high nutrient content and large quantity generated from the rapid growth of aquaculture sector. In this study, Tetraselmis chuii cultured in different media with or without wastewater was evaluated for its growth, proximate composition and carotenoid production. The results showed that significantly(P < 0.05) higher growth(4.3 × 105 cells mL^(-1)) and protein(56.4% dry weight), lipid(44% dry weight) and carbohydrate(20% of dry weight) contents were found in T. chuii when they were cultured in the combination of both wastewater and Conway(wastewater + Conway) medium. However, carotenoid production of T. chuii was significantly increased(P < 0.05) when it was cultured in wastewater only, followed by Conway + wastewater and Conway medium only. Therefore, the incorporation of wastewater with commercial medium Convey is recommended for a cost-effective microalgae culture, as well as for the enhancement of growth and nutritional content of microalgae.展开更多

This study was conducted to give an idea whether television viewing and parental attention can assist students to take a decision of choosing major at the senior high school. This study used descriptive method which analyzed the correlation among television viewing, parental attention, and the students＇ motivation to choose a major. The sample of this study consisted of 100 students of the state senior high school in Malang, East Java. The finding shows that there is no correlation among television viewing, parental attention, and the students＇ motivation to choose major at the senior high school. In other words, the possibility of choosing the major can be attributed to some other factors such as interest, talent, aspiration, and other expectation to achieve their goals展开更多

The original meaning was the day of birth. After the Song Dynasty, the literati began to use it to refer to birthdays. By the end of the Ming Dynasty, they had been calling their birthdays “chudu” once they celebrated it and they were so keen on birthday celebrations. Gu Yanwu pointed out that the word “chudu” only fits “the old ministers （or the exiled ministers） who lamented the crash of the Yingcapital of the country of “Chu” such as Qu Yuan. At the same time, its use in Huang Zongxi’s and Wang Fuzhi’s birthday poems is also consistent with this context. The unique situation and mood of the adherents led them to be close to Qu Yuan and Wen Tianxiang, which bestowed “chudu” the special meaning. It is very suitable for the ministers who suffered the crash of their Dynasties or those who were exiled distantly to express their feelings about the old dynasties and old friends. After these people, Chen Yinke consciously acknowledged this layer of interpreting “chudu” and used it, which has not only enriched the connotation of “chudu”, but also extended its cultural life. From Qu Yuan to Wen Tianxiang, until Gu Yanwu, Huang Zongxi, Wang Fuzhi, and then to Chen Yinke, we can take a glimpse of the spiritual world of the Chinese adherents of Dynasties.展开更多

From one side, there is the urge to comprehensively preserve cultural resources. At the same time, opportunities of economic growth should be made available and needs of contemporary living maintained and nourished. The main aim of this paper is to reconcile probable incompatibilities between such missions through promoting ＂sensitive＂ redevelopment approaches in historic cities. The paper focuses on the city of Luxor, Egypt with its immensely capturing yet quite undermined legend： the Avenue of Sphinxes. In Luxor, the injection of nonintrusive interventions presents itself as a highly potential candidate in protecting and enhancing the experience of the avenue while meeting contemporary needs of living. Adopting less sensitive development approaches can lead the quality of experiencing the whole city to be worsened for the increasing numbers of tourists and locals.展开更多

Different Plant growth regulators＇ combinations, base media and carbon sources were studied for callus formation and organ differentiation from balsum pear anthers. The result showed that the best media for callus inducement was： MS＋BA 0.5 mg/L＋NAA 0.2 mg/L＋ 2, 4-D 0.5 mg/L＋KT 2.0 mg/L, with 3% sugar and 0.8% agar. The best media to induce roots from balsum pear anther callus was： MS＋NAA 0.05 rag/L＋ KT 0.5 rag/L, with 3% sugar and 0.8% agar. Most of adventitious roots from callus were triploid（2N=3X=33）展开更多

In this review, we searched the MEDLINE database for all full texts and/or abstract articles published in English with content related to oocyte IVM mainly between 2000 and 2016. Many different aspects of the IVM method may influence oocyte potential,including priming, gonadotrophin, growth factors, and culture times. The culture conditions of IVM result in alterations in the oocyte or cumulus cell transcriptome that are not observed under in vivo culture conditions. Additionally, epigenetic modifications, such as DNA methylation or acetylation, are also different between in vitro and in vivo cultured oocytes. In sum,current IVM technique is still not popular and requires more systematic and intensive research to improve its effects and applications. This review will help point our problems, supply evidence or clues for future improving IVM technique, thus assist patients for fertility treatment or preservation as an additional option.展开更多
