Seagrass has a crucial role in coastal ecosystem, but rapid coastal development, extreme climate change, lack of knowledge and appreciation of the community constantly threaten this declining resource. Monitoring of seagrass meadows is important to generate knowledge and fill data gaps. Nine seagrass meadows were surveyed in Island Garden City of Samal (IGACOS) to (1) assess the demographic status (2) quantify clonal reproductive capacity (3) compare the abundance and density (4) determine the relationship of abundance, density and net recruitment and (5) find out the influence of abundance, density and monsoon exposure to the net recruitment of seagrass Thalassia hemprichii and Cymodocea species. Modified Braun-blanquet method and age reconstruction techniques were used to accomplish these objectives. Results reveal that in IGACOS, Cymodocea sp. is abundant, dominating (88 shoots/0.25m-2) and rapidly expanding (net recruitment 0.10 ln units/year-1) compared to T. hemprechii. ANOVA test discloses significant differences in abundance and density among seagrass meadows. High correlation is also noted between abundance and net recruitment. Regression analysis suggests a negative influence of density (-0.051) and monsoon exposure (-0.136) to net recruitment. Comparing Northeast (NE) sites to Southwest (SW) sites suggests monsoon exposure related impacts particularly on seagrass meadows located at the Northeastern side of the Island.

The aim of this research is to evaluate the applied programs or laser space tech in communication. Laser communication links in space are attractive alternatives to present-day microwave links. This tutorial describes the essential concept or the functions of an ocular ending on board a spacecraft. It refers to the differences between limited-space ocular links on one hand or glass fiber techs or microwave directional links on the other hand. The needs on data transmitters or receivers as well as on ocular ramuses or pointing, acquisition or exploring methods are discussed. Typical application scenarios are out-lined, experimental techs or their technologies are shown.

Children with disabilities in writing and less writing failure are one of the special groups in learning. Failure in dictated have this characteristics that students write words by moving letters, spelling errors, punctuation errors, and reversing letters and words, writing, writing mistakes. Defects of learn can affect grow, learn, education for children. In this article different opinion solutions and suggestions will be reviewed.

Recent research aims to study the Neurofeedback Effectiveness on the Learning Skills of Elementary School Students. Methodology: the research was based on experimental method and pre-test and post-test with control group has been used. So, among female students with related parameters to participate in the research just 50 ones were choice. Three practice sessions per week for 20 were determined for each three groups. Both experimental and control groups participated in Neurofeedback learning sessions (promoting the Alpha wave, Alpha-Theta protocol) in addition to school practices. However, experimental group recieved real feedbacks and also similar implementation process for simulated neurofeedback group, there is no relationship between these feedbacks and neuro-activities. Standard school rules used to estimate the students record. Additionally, their changes studied and compared in these two stages. Compared to other groups, increasing the mean of records in real Neurofeedback group significantly presented as the result of analysis the unilateral covariance (p<0.05), also, however, mistakes decreased for each person in real Neurofeedback group, there was no significant different between these changes in pre-test. Neurofeedback training is effective on performance improvement with capable of operant conditioning of brain waves. So, with regard to the results, suggests that Neurofeedback training used to improve the school work of elementary students.
