A Review on the Renewable Green Energies in Northern Mindanao, Philippines
Pauline Mae N. Comaling,Abdurrazzaq G. Maraye 국제과학영재학회 2022 APEC Youth Scientist Journal Vol.14 No.1
It is well-established that non-renewable energy sources adversely affect the environment and human health. Nonetheless, the Philippines continues utilizing this energy source as it is more accessible than the alternatives. Non-renewables, especially coal, are cheap; there is ease and familiarity with non-renewables and a lack of knowledge and experience in utilizing renewable energy. However, as the consumption of this energy source grew, the challenge involving the inevitable depletion of this resource arose. In response to this problem, the Philippine government created the National Renewable Energy Program (NREP), which aims for 15.3 gigawatts of renewable power capacity by 2030. Despite this, coal remained the highest power share, and renewable energy was ignored. Although there are regions in the Philippines with existing renewable energy projects, it was mostly hydropower and solar power. Moreover, the current projects do not hit the target capacity stated in the NREP. There are still various renewable energy sources that could be utilized. Aside from solar power and hydropower, there is potential for biomass, wind, and geothermal energy utilization. This study has been conducted to evaluate the existing and the possible renewable energy sources in Northern Mindanao, Philippines (Region 10), and assess the resources’ potential.
Genome of Bifidobacteria and Carbohydrate Metabolism
Pauline Bondue,Véronique Delcenserie 한국축산식품학회 2015 한국축산식품학회지 Vol.35 No.1
In recent years, the knowledge about bifidobacteria has considerably evolved thanks to recent progress in molecular biol-ogy. The analysis of the whole genome sequences of 48 taxa of bifidobacteria offers new perspectives for their classifica-tion, especially to set up limit between two species. Indeed, several species are presenting a high homology and should bereclassified. On the other hand, some subspecies are presenting a low homology and should therefore be reclassified intodifferent species. In addition, a better knowledge of the genome of bifidobacteria allows a better understanding of the mech-anisms involved in complex carbohydrate metabolism. The genome of some species of bifidobacteria from human but alsofrom animal origin demonstrates high presence in genes involved in the metabolism of complex oligosaccharides. Thosespecies should be further tested to confirm their potential to metabolize complex oligosaccharides in vitro and in vivo.
Croissance verte et interventionnisme économique : une nouvelle place pour la puissance publique?
Pauline Marcantoni 유럽헌법학회 2012 유럽헌법연구 Vol.12 No.-
2008년의 경제 및 금융위기는 최근 몇 년간에 작용했던 경제시스템의 부분적 문제의 돌파구였다. 경제위기가 자유주의 포기의 문제나 디플레이션의 문제가 아니라면, 몇 몇 기능장애에 이르게 하는 지나침을 돌아볼 필요가 있고, 성장의 새로운 기반을 부여할 필요성이 있다. 한 층 더 강화된 ‘녹색’으로 향하는 해법은 30여 년 전부터 사회가 직면한 동시대의 다른 큰 문제의 시각을 갖도록 요구하고 있다. 즉, 환경의 위기이다. 환경의 위기는 오늘날 사회기능이 자연자원의 유한성 안에서 자신의 한계를 발견할 것이다. 자연자원의 유한성으로 여전히 오랫동안 과도하게 개발된 것을 더 이상 허락하지 않을 것이고, 현재의 상태와 같은 오염을 유발되게 하지 않을 것이다. 녹색성장은 장기적으로 에너지 자원과 재생할 수 없는 자원을 더 적게 혹은 더 잘 쓰는 경제성장이다. 뿐만 아니라 삶의 환경과 생물의 다양성을 더 존중하는 것이다. 본 논문에서는 녹색성장의 이름으로 경제에 대한 국가의 다양한 관여 형태를 다루고 있다. 특히 오염비용의 국제화와 각 시장의 해결책 그리고 국가가 소비자로서의 역할을 하는 것등을 다루고, 두 번째 논점으로서 변화하지 않는 경제 틀 안에서 혁신적 경제 관여가 가능하지에 대하여 다루고 있다. 즉, 경제적 한계, 법적 한계 그리고 정치적 한계에 대하여 살펴보았다. La «crise» financière et économique de 2008 a été le 시동장치 «déclencheur» 도전d’une remise en cause partielle du système économique tel qu’il fonctionnait depuis quelques années. S’il ne fût question ni d’abandon du libéralisme ni de décroissance, il est apparu nécessaire de revenir sur les excès ayant conduit à certains 고장dysfonctionnements et de donner un nouveau fondement à la croissance. La solution tendant à la rendre plus «verte» s’est imposée au regard d’un autre grand problème contemporain auquel fait face la société depuis une trentaine d’années : la crise environnementale. Il est aujourd’hui admis que le fonctionnement de la société trouvera aussi ses limites dans la 유한성finitude des ressources naturelles, qui ne pourront encore longtemps être surexploitées et polluées tel qu’elles le sont actuellement. De la mise en perspective de ces deux circonstances, est ressortie la possibilité d’une croissance en partie fondée sur l’objectif de réduction des atteintes à l’environnement. La croissance verte est une croissance économique qui, à long terme, utilise moins - ou mieux - la ressource énergétique et les matières premières non renouvelables, et est plus respectueuse de la biodiversité et du 생활환경cadre de vie.
Effects of tensioning forces on the structural behavior of cable-stayed bridges
Pauline Lin Li Lam,Thomas H.K. Kang 국제구조공학회 2022 Steel and Composite Structures, An International J Vol.43 No.4
Optimization in distribution of stay cable forces is one of the most difficult aspects in the design of cable-stayed bridges. This article attempts to examine tension force influence on structural behavior of cable-stayed bridges. For the examination, finite element modeling using nonlinear static and nonlinear modal analyses was completed and compared to structural experimental results. Variables analyzed in this parametric study were: 1) Number of stay cables; 2) Tension of the stay cables, and 3) Stay cable pattern - harp and semi-fan patterns. Though the findings from the analysis are limited to the tested models, the study gives insight on the structural behavior of actual cable stayed bridges.
