The microstruc-ture of normal and vitrified shoots and the characteristics of their stomas on leaf surface were compared by paraffin section and leaf epidermis-tearing method. The results showed the palisade tissue of Aronia melanocarpa El oit consists of 2-3 lay-ers of cells. The stomas on lower epidermis cave in, and are smal and dense. There are abundant vessels and sieve tubes in stems. ln contrast, the main veins of vitrified shoots are unobvious, messy and irregular. The boundary between pal-isade tissue and spongy tissue is not obvious. The stomas open circularly and bigly. The stems are swel ing and thick, but the pith parenchyma cells are broken.展开更多

The descriptive correlation method was used, which utilized a survey questionnaire as the primary source in acquiring the data. The findings showed that the majority of the respondents were young, most of them were married and had finished elementary degree. It was observed that their participation in electoral, policy-making, and peace processes was high but vote buying, political ideology, and corruption were considered to be their problems. Despite cultural barriers, a clear understanding of their role as Muslim woman can increase their participation. Hence, total reform in the government as well as the Barangay should be done including their participation for the training programs on leadership, accountability and transparency, human and political rights awareness as well as the Shariah Law and the Philippine Constitution. Political party system that has a strong alliance to other political parties shall also be established in order to assure their participation. Linkages to other civil society like class-based organizations, occupation-based associations, and interest-based societies shall be tapped by the leaders of Bangsamoro women.展开更多

The sensor is designed based on Morphology Dependent Resonances （MDR） which follows Maxwell＇s electromagnetic equations. In this paper, we have presented a novel technique to integrate chemical science and optical technology by using OCRR. Optical resonances of electromagnetic wave propagations in dielectric micro-ring resonator have been developed based on asymptotic approach. Parametric studies based on developed asymptotic expression have been presented to determine the resonance frequency at particular chemical composition. Finite element simulation is used to predict the performance of the sensor and found encouraging results for odorant sensing. Parametric studies show that present study will help to develop novel OCRR sensors tbr micro/nano technology and biomedical applications.展开更多
