The polymethyl-methacrylate (PMMA)-based composites were prepared using goose feather fibers at different diameters. The fibers, which were washed and dried, cut through the shaft, and their sizes were shrunk to short fiber form. Then the obtained short fibers were added into acryl matrix in portions of 2%, 4%, 6%, and 8% in volume. The mixture containing goose feather fiber was shaped via free casting method, and the goose feather fiber/PMMA composites were obtained. The samples, which were processed in accordance with the standards of test to be implemented after the thermal curing process, were characterized in terms of the mechanical properties after being evaluated by using three-point flexure test and impact test. For the goose feather-added composites, a significant increase was observed in rupture resistance, flexural strength, and flexure module. The flexure test curves of composites clearly revealed the slow and stable crack enlargement. Micro mechanisms of toughening and rupture processes were observed under the light of microstructure of rupture surfaces. The results of present study showed that the goose feather can be used as an important reinforcing material for bio-composites.

This paper presents the implementation of maximum power point tracking （MPPT） with fuzzy logic controller. For cost consideration, an inexpensive 8-bit microcontroller, PIC 16F877A, is selected and programmed with C language and integer variables For evaluation, the implemented fuzzy logic controller （FLC） is compared with the MPPT controller of using perturbation and observation （P＆O）. Both types of MPPT controllers are tested on the same voltage source with a series-connected resistor. Experimental results show that the implemented FLC with appropriate design meets the control requirements of MPPT. The FLC based on linguistic fuzzy rules has more flexibility and intelligence than conventional P＆O controller, but the FLC spends more RAM and ROM spaces than the P＆O tracker does.

Cultural and Religious Studies 2017年第1期5卷 1-16页

作者： Indira y. Junghare University of Minnesota Minneapolis USA

In this age, the challenges of urbanization, industrialization, globalization, and mechanization have been eroding the stability of communities. Additionally, every existence, including humans, suffers from nature＇s calamities and innate evolutionary changes--physically, mentally, and spiritually. India＇s cultural tradition, being one of the oldest, has provided diverse worldviews, philosophies, and practices for peaceful-coexistence. Quite often, the multi-faceted tradition has used different methods of syncretism relevant to the socio-cultural conditions of the time. Ideologically correct, ＂perfect＂ peace is unattainable. However, it seems necessary to examine the core philosophical principles and practices India used to create unity in diversity, between people of diverse races, genders, and ethnicities. The paper briefly examines the nature of India＇s cultural tradition in terms of its spirituality or philosophy of religion and its application to social constructs. Secondarily, the paper suggests consideration of the use of India＇s spirituality based on ethics for peaceful living in the context of diversity of life.

作者： Bradley y.Bartholomew Independent Researcher SydneyAustralia

This paper draws many parallels between Guy Debord‟s Society of the Spectacle and the philosophy of Friedrich Nietzsche particularly Beyond Good and Evil and Thus Spake Zarathustra in anticipating and predicting the rise of the Superman,the 45th President of the United States Donald *** identified the spectacle as“The moment when the commodity has achieved the total occupation of life”.What Debord didn‟t foresee is the rise of Donald *** which Nietzsche would describe as the“noontide”or transcendence of the society of the spectacle,and indeed the eternal recurrence of the society of the *** spectacle is capable of regenerating itself in perpetuity through the essential slogan in Trumpism-make America great again!Nietzsche prophesizes that nihilism will be turned into the new religion where he predicts the rise of the *** it will be argued that Donald *** is the nominal head of this new religion and may therefore be identified as the Anti-Christ.

International Relations and Diplomacy 2017年第7期5卷 371-388页

作者： Ahmed y. Zohny Coppin State University Baltimore USA

Recent scholarship on great-power foreign policy and diplomacy undermines President Obama＇s realist approach compared to his predecessor Bush＇s neoconservative idealism approach to the Middle East＇s geopolitical enduring Arab-Israeli conflict, the rising power of political Islam, the unexpected events of the Arab Spring, along with the challenge of democratization. This article genealogically examines President Obama＇s foreign policy and diplomacy in response to the chronology of the unfolding events of the Arab Spring in Egypt, Tunisia, Libya, Syria, Bahrain, and yemen that witnessed the Arab Spring of 2011. President Obama and his top diplomats＇ performances in response to each country recounting events were assessed, critically analyzed, and compared to the other in terms of the U.S. bilateral relations with each country, U.S. national interests, and her strategic goals in the Middle East region. The researcher analyzed the aforementioned issues within the complicated realities of the Palestinian/Arab Israeli conflict, the rising power of political Islam on the Middle East＇s ground manifested by the Muslim Brotherhood rise to power in Egypt, ISIS in Iraq and Syria, and Libya, and the rivalry between Sunni and Shia＇a---supported by Iran in Lebanon, Syria, Bahrain, and yemen. The research findings indicate that in a broader sense Obama＇s foreign policy and diplomacy has been a movement away from the U.S. foreign policy and diplomacy since World War II, particularly when he （Obama） decided that the U.S. should abstain from exercising the veto power at the United Nations （UN） on resolution 2334 in support of the Palestinian right to have their own state, thus following the consensus of other permanent members of the UN security council and international law.
