Solar light,seawater temperature,and nutrients,which one is more important in affecting phytoplankton growth?

Based on research results on the impacts of solar light,seawater temperature,and nutrient available to phytoplankton growth and changes in phytoplankton physiology and assemblage,we discussed the order of influence of these factors.By clarifying the mechanisms and processes of the impacts by these factors,we have determined the rising order of the importance as solar light,seawater temperature,and nutrient silicon (Si).Therefore,for human interests in sustaining economic development,the first thing to be considered is the input of nutrient Si into the ocean,followed by seawater temperature change.

On the Practice of Pedagogic Corpus Linguistics With Secondary School Iranian English Language Learners

The gap between the theories of second language acquisition and their practice in materials development has been a controversial issue in the field of applied linguistics. Recently, the findings of corpus linguistics have narrowed the gap. However, their practice, especially in the realm of vocabulary acquisition, has encountered pedagogic problems in the classroom because the authentic nature of the words in corpus-based examples was beyond the level of learners＇ comprehension which paves the way for the practice of pedagogic corpus linguistics. Therefore, the purpose of this study was to practice pedagogic corpus linguistics, and mainly data-driven learning, with the first year secondary school English language learners in Iran in terms of their vocabulary acquisition. To do so, 28 students participated in the study. Examples from the British National Corpus for the main words of each unit of their course book, Prospect 1, were presented to them in a course of 16 sessions. Those which were beyond their understanding were eliminated and those comprehensible for them, the pedagogic ones, were selected based on their reports regarding the comprehensibility of each corpus-based example.

Research Achievements and Trends in Forest Products Science in Indonesia

The supply of logs for wood industries during the period 2004-2008 was 13.5-32 million cubic meters per year. Logs from plantation forest reached about 65%, which was exploited from industrial plantation forest, Perum Perhutani, as a government enterprise, community forest and estate. The changing log supply from natural forest to plantation forest implies changing of wood species, cutting cycle, log diameter and wood properties. Research concerning the utilization of fast growing species, small log diameter, lesser used species and other llignocellulosic material have been intensively done by some research institutes and universities, and were related to wood properties, wood properties enhancement, wood chemistry, bio-composite, wood engineering, and also non-timber forest products.

Social Networks Among Migrants in Saudi Arabia （SA）： Opportunities and Implications

Domestic Tourism Development Planning Research Review

The domestic tourism development planning began in 1985. According to the research achievement distribution situation, tourism development planning research can be divided into initial stage（ 1985-1998）, development stage（1999-2004） and prosperous stage（2005 till now）. The research achievement has the features of earlier academic research start, slow quantity increase, rapid growth of newspaper quantity, wide distribution of region, research achievement total increase speed slower than social scientific research achievement quantity growth. The research has three aspects of problems： one is insufficient academic research system; two is report lacks of depth, continuity and unity; three is research achievement has overall decreasing trend. The domestic tourism development planning should strengthen the theoretical research, combine with theory and practice; strengthen thematic reports, mining depth information, and give full play to supervision function.
