PUC Campinas / This study aims to analyze the influences that a religious model has on a religious community, stablishing a correlation between Max Scheler?s conception of religious model, ethical progress and religious experience with the bible text Sermon on Mount, specially, the Antitheses (Mt 5, 17-48) and the Lord?s Prayer ritual orientation. With this purpose, in this study is made a research to identify the religious model from Matthew?s community to understand the powerful influence to the construction of the meanings in the social world of this community. This study was possible approaching Max Scheler?s phenomenological works to contextualize the religious model, religious experience and ethical progress concepts. As well as, it was necessary to go deep in historical, social and exegetical aspects from Matthew?s bible text. It was necessary to enable the correlation method associated to the Matthew?s bible text phenomenological analyses to apply Scheler?s horizon to the bible reality, to answer what is the relation between a religious model and religious experience in the community from the Matthew?s bible text. / O presente trabalho tem o prop?sito de analisar as for?as de influ?ncia que o modelo religioso exerce em uma comunidade religiosa. Isso se fundamenta a partir da correla??o estabelecida entre a conceitua??o de modelo religioso, progresso ?tico e experi?ncia religiosa ao mundo social apreendido do texto b?blico o Serm?o da Montanha. A an?lise ter? como objeto a releitura do texto o Serm?o da Montanha, localizado no Evangelho de Mateus, em espec?fico, as Ant?teses (Mt 5.17-48) e a orienta??o ritual?stica do Pai-Nosso (Mt 6.5-15), ? luz do pensamento de Max Scheler. Partindo desse prop?sito, busca-se identificar o modelo religioso da comunidade mateana e compreender a for?a de influ?ncia desse modelo nos significados do mundo social dessa comunidade. O arcabou?o conceitual foi constru?do tendo como base obras do per?odo fenomenol?gico de Max Scheler para contextualiza??o dos conceitos de modelo religioso, progresso ?tico e experi?ncia religiosa. Foi necess?ria a constru??o de uma abordagem cr?tica dos aspectos hist?ricos, sociais e exeg?ticos da per?cope mateana. Por isso, foi poss?vel, a partir do m?todo da correla??o associado ? an?lise fenomenol?gica do Evangelho de Mateus, aplicar o horizonte conceitual scheleriano ? realidade dos vers?culos b?blicos, a fim de responder qual a rela??o entre modelo religioso e experi?ncia religiosa da comunidade mateana.

For each sample, the total phenolic and the total flavonoid contents were analyzed by the Folin-Denis and aluminum chloride (AlCl3) methods, respectively. Also, the antioxidant activity (%AA and EC50) for all the honey samples was evaluated, as well as for some phenolic acids and flavonoids, used as standards. The determination of the antioxidant capacity was carried out by the method of trapping the 2,2-diphenyl-1-picryl-hydrazyl organic radical (DPPH) by antioxidant compounds, resulting in an absorbance decrease at 520 nm. The analyzed honeys were classified as monofloral or heterofloral. For the monofloral samples, it was observed that Anadenanthera honeys showed the highest average value for total phenolics (112,60 mgEAG/100g) and also for the antioxidant capacity (59,93 (AA)mgEQC/500g or 18,92 mg/mL if expressed as EC50), while the Eucalyptus honeys showed the highest mean for total flavonoids (9,17 mgEQC/100g). With these results, a comparative study was carried out with diverse honey samples of different regions, in terms of total phenolic and flavonoid content, antioxidant capacity and some physico-chemistry parameters (HMF, acidity, pH, humidity, water activity and color intensity). Comparison of these results allowed to observe that darker honeys showed both higher antioxidant activity and the highest values for total phenolic and flavonoid contents, as well as for all the other physico-chemical parameters. / O objetivo deste trabalho foi avaliar os teores de fen?licos e flavon?ides totais de sessenta amostras de mel de Apis mellifera comercializadas em diferentes mesorregi?es do estado do Rio do Janeiro (Metropolitana, Sul, Centro, Noroeste Fluminense e Baixada Litor?nea). Para cada amostra foram analisados os totais de fen?licos e flavon?ides, atrav?s dos m?todos de Folin-Denis e cloreto de alum?nio (AlCl3), respectivamente. Foi determinado, tamb?m, o potencial da atividade antioxidante (%AA e CE50) para todas as amostras de mel, bem como para alguns padr?es de ?cidos fen?licos e flavon?ides. O m?todo utilizado para determinar a capacidade antioxidante foi o de captura do radical org?nico 2,2-difenil-1-picril-hidrazil (DPPH) por antioxidantes, produzindo um decr?scimo da absorb?ncia a 520 nm. Os m?is avaliados foram classificados de monoflorais e heteroflorais. Para os monoflorais foi observado que os m?is de Anadenanthera apresentaram a maior m?dia em totais de fen?licos (112,60 mgEAG/100g), e tamb?m a maior atividade antioxidante (59,93 (AA)mgEQC/500g ou 18,92 mg/mL em termos de CE50), enquanto os m?is de Eucalyptus apresentaram, em m?dia, o maior conte?do de flavon?ides totais (9,17 mgEEC/100g). A partir dos resultados obtidos foi feito um estudo comparativo entre as v?rias amostras de m?is de diferentes regi?es quanto ao teor de fen?licos e flavon?ides totais, a atividade antioxidante e algumas propriedades f?sico-qu?micas (HMF, acidez, pH, umidade, atividade de ?gua e intensidade de colora??o). Ao comparar esses resultados, foi poss?vel observar que os m?is mais escuros apresentaram uma maior atividade antioxidante e uma maior quantidade de fen?licos e flavon?ides totais, bem como valores mais altos para todos os outros par?metros f?sico-qu?micos comparados.

從賓禮到禮賓—外使覲見與晚清涉外體制的變化 / From binLi to protocol: the courtesy ritual of enovys and the change of foreign-related system in the late qing dynasty

尤淑君, Yu, Shu Chun Unknown Date (has links)
本論文為結合政治史、外交史及禮儀史的著作。以學界對晚清外交的研究為基礎,聚焦於「外國公使覲見禮」的制訂,並利用晚近整理出版的多國檔案、日記、回憶錄,及藏於中央研究院近代史研究所的總理各國事務衙門檔案、外務部檔案等資料,重新討論清代賓禮體制的原型、變體及其過渡到西式外交禮儀的過程,分析中、西禮制的衝突根源,進而探討「天下秩序」與中國近代政治文化的關聯。經本論文的考察,研究成果有四。 本論文先概論清代「賓禮體制」的運作過程,並說明康熙、雍正年間的「賓禮體制」具有相當大的彈性空間,其制禮原則不只是「朝貢禮」,還有用於不稱臣納貢者的「客禮」,作為「朝貢禮」的補充。 其次,說明咸豐君臣在《天津條約》的約束下,不得不允許公使駐京等條款。但總理各國事務衙門的設立,不完全是清政府因應對外交涉的新局面,更多是出於維護「賓禮體制」的考量,並延續過去「督撫外交」的成例,由三口通商大臣、五口通商大臣作為對外交涉的第一線。 再者,總理各國事務衙門援引康熙、雍正年間款待俄國使節團之事,重新提出「客禮」,讓「鞠躬禮」與「跪拜禮」不再是絕對的對立,反而有變通的空間,讓外國公使得行「鞠躬禮」。清政府利用「客禮」概念,以「天下秩序」包容歐美各國與中國的政治關係,再將外國公使定位為皇帝的「客臣」,並將「外國公使覲見禮」解釋為皇帝優禮外使的恩典,遂得到中國官民的認同,維護皇帝作為「天子」的至尊地位。 第四,《辛丑和約》簽訂後,清政府雖透過擯者轉譯的方式,讓外國公使仍是皇帝的「客臣」,不致出現君臣逆位的狀況,但清政府只能在形式上維持皇帝的權威。外務部不能再像過去那樣用「名分秩序」,作為涉外禮儀的制禮原則,「西禮中用」已是不可避免的趨勢,表示清政府無法再以「天下秩序」包容歐美各國與中國的關係,只能藉由「國際法」的慣例,利用條約去約束外國官民的行動,以挽回中國的利權。 最後,經本論文對「外國公使覲見禮」的考察,得知「賓禮」到「禮賓」的改變,並非一蹴而成的,也不是全出於外國公使的逼迫。清政府面對外來刺激時,自有其內部轉換的機制,不僅有外在形式上的變革,更有內在觀念的調整,故清政府提出「客禮」概念,作為中禮與西禮的過渡禮儀,也是「天下秩序」與「國際法」的思想銜接。當「客禮」無法再解釋公使請覲,清政府廢除禮部,「賓禮體制」宣告結束,「天下秩序」也不再是清政府對外關係的中心思想。

We consider a porous medium rigid and incompressible saturated by an electrolyte solution containing four monovalent ionic solutes completely diluted in the aqueous solvent. Initially we developed the modeling electrical double layer how objective to compute the electrical potential, surface density of electrical charges and considering two chemical reactions, we propose a 2-pK model for calculating the chemical adsorption occurring in the domain of electrical double layer. Having the nanoscopic model, we deduce a model in the microscale, where the electrochemical adsorption of ions, protonation/ deprotonation reactions and zeta potential obtained in the nanoscale, are incorporated through the conditions of interface uid/solid of the Stokes problem and transportation of ions, modeled by equations of Nernst-Planck. Using the homogenization technique of periodic structures, we develop a model in macroscopic scale with respective cells problems for the e ective macroscopic parameters of equations. Finally, we propose several numerical simulations of the multiscale model for uid ow and transport of reactive ionic solute in a saturated aqueous solution of kaolinite. Using nanoscopic model we propose some numerical simulations of electrochemical adsorption phenomena in the electrical double layer. Making use of the nite element method discretize the macroscopic model and propose some numerical simulations in basic and acid system aiming to quantify the transport of ionic solutes in porous media electrically charged.

Tropical fruit cultivation is an important productive segment in Brazilian Northeast. Its industrialization generates solid wastes as co-products, with potential environmental impact. Considering the recognized bioactive content of fruit and its derivatives, this research has the objective of investigating acerola (Malpighia glabra L.), caj?-umbu (Spondia ssp), jambolan (Syzygium cumini) and pitanga (Eugenia uniflora) dried wastes obtained by spouted bed drier. It was analyzed the physical-chemical composition, solubility and microphotographic aspect of these dried wastes. Besides this, it was also evaluated the bioactive content, antioxidant activity and inhibitory activity against aamylase and a-glycosidase enzymes of water and ethanol (70%, 80% e 100% v/v) extracts prepared from fruit dried wastes, as well as their possible correlations. The dried fruit wastes showed high phenolic (606.04 to 3074.6 mg GAE eq/100 g sample), anthocyanin (478.7 mg/100 g for jambolan) and ascorbic acid (2748.03 mg/100 g for acerola) contents, as well as high antioxidant DPPH activity (14.27 a 36.30 mg Trolox eq/g sample). The extracts exhibited moderate to high a-amylase inhibition (23.97% a 76.58%) and high α-glycosidase inhibition, which 99.32% peak was reached for ethanol 70% pitanga extracts. It was also observed great positive correlation between phenolic content and DPPH activity (0.97 for acerola), anthocyanin (0.95 for jambolan) and α- glycosidase inhibition (0.98 for acerola). The α-glycosidase inhibition also correlated well with the antioxidant activity for all fruit extracts. The results show that these dried fruit wastes are valuable material for further applications as functional ingredients / As frutas possuem importantes compostos bioativos, dentre eles os compostos fen?licos.

Geovisualization of boreal peatland architecture in a three dimensional hydrogeological framework using ground penetrating radar and LiDAR at Mariana Lakes, Alberta, Canada

Shulba, William Paul 07 June 2021 (has links)
Communicating science in three-dimensional (3D) multimedia is an immersive and interactive way to explore scientific processes (Signals and Communication Technology, 2019). Geovisualization is an emerging 3D multimedia method for visual analysis, synthesis, and presentation of geospatial, geologic, and geophysical data (MacEachren & Kraak, 2001). There is an identified need to develop scientific communication tools to further understand boreal peatland evolution, hydrogeology, ecology, and geochemistry (Bubier et al., 2003) since the International Union of Conservation of Nature asserts that peatlands are among the most valuable ecosystems on Earth, critical for preserving global biodiversity, providing drinking water, minimising flood risk, preventing wildfire, and mitigating climate change (Hama et al., 2000). The intention of this thesis is to communicate a novel approach to geovisualize boreal peatland architecture using Light Detection and Ranging (LiDAR) and Ground Penetrating Radar (GPR). GPR and LiDAR have been used to create 3D subsurface geovisualizations for archaeology (Kenady et al., 2018; Schultz & Martin, 2011) and resource geology (Corradini et al., 2020; Koyan & Tronicke, 2020) although application to peatland hydrogeology is uncommon. Point-source hydrogeological and geochemical data were integrated with 3D geological models to estimate carbon and nitrogen storage in an archetypal boreal peatland near Mariana Lakes, Alberta. Peatland geometry resembled a shallow lake basin with depths greatest in fens (>10 m) and thinnest in bogs (<2 m). Hydraulic conductivity was only a few meters per year and vertical groundwater movement was limited. Sequestered carbon and nutrients increased with depth. The average concentration of dissolved ammonium was 3 grams per cubic metre of peat (g/m3), 5g/m3of Total Kjeldahl Nitrogen, 60g/m3 of dissolved organic carbon and 200g/m3 of dissolved inorganic carbon. Tritium detection from atmospheric atomic weapons radionuclide fallout revealed that in deeper anaerobic peat (catotelm), tritium was absent, signifying groundwater was older than 50 years and not mixed with meteoric waters. Fen catotelm channels are likely acting as gravity-driven hydraulic traps (Tóth, 1999). / Graduate

Les patrons latitudinaux de diversité taxonomique et fonctionnelle diffèrent entre les bryophytes et les plantes vasculaires dans les tourbières

Deschenes, Elise 04 1900 (has links)
L’objectif de ce mémoire était d’évaluer l’influence de la latitude, de variables abiotiques et du type de tourbières (bog ou fen) sur la diversité des plantes vasculaires et des bryophytes. Des inventaires ont été réalisés dans 380 tourbières du nord-ouest du Québec (49° à 55° N). Les effets de la latitude, de la continentalité, du climat et de variables abiotiques locales sur la diversité α (richesse spécifique et dispersion fonctionnelle), la diversité β (indices LCBD) et la composition ont été évalués pour les deux groupes de plantes. La diversité α des bryophytes augmentait vers le nord, alors que la diversité α des plantes vasculaires présentait des patrons différents dans les bogs et les fens en réponse à la latitude. Il y avait une homogénéisation taxonomique et fonctionnelle vers le nord pour les deux groupes de plantes et dans les deux types de tourbières. Les variables environnementales avaient des effets différents sur les deux groupes de plantes, dépendamment de l’indicateur de biodiversité utilisé. La composition taxonomique et fonctionnelle des bryophytes et des plantes vasculaires étaient principalement structurées par les conditions locales contrastantes entre les bogs et les fens, tandis que les variations bioclimatiques le long du gradient latitudinal jouaient un rôle secondaire. Les futures études et politiques de gestion des milieux naturels devraient tenir compte de plus d’un indicateur de diversité et considérer les différences entre les deux écosystèmes et les deux groupes de taxons afin de planifier les efforts de conservation et afin d’évaluer les effets des changements environnementaux. / This study aimed to evaluate the influence of latitude, abiotic variables on vascular and bryophyte diversity in bogs and fens. Inventories were conducted in 380 peatlands in northeastern Québec (49° to 55° N). Changes in α-diversity (species richness and functional dispersion), β-diversity (LCBD indices) and composition in response to latitude, continentality, climate, and local abiotic variables were evaluated for both plant groups. Bryophyte α-diversity increased northward, while vascular α-diversity showed contrasting patterns in bogs and fens in response to latitude. Environmental variables had different effects on both species’ groups, and patterns varied depending on the diversity indicator used, as α- and β-diversity and functional and taxonomic diversity were often decoupled. There was taxonomic and functional homogenization with latitude for both groups of plants in both habitats. Bryophyte and vascular taxonomic and functional composition were primarily structured by contrasting local conditions in bogs and fens, while bioclimatic variations along the latitudinal gradient played a secondary role. These results highlight the contrasting biodiversity patterns in both peatland types and the importance of local habitat conditions in structuring vascular and bryophyte biodiversity. Therefore, future studies and policies should include more than one diversity indicator and consider the differences between ecosystems and taxon groups when evaluating the effects of environmental changes on biodiversity and planning conservation.

Long term restoration effects : Effects of restoration measures on restoration success in nature reserves in acidic fen, buffered fen, dry heather, wet heather, and wet grassland in Drenthe, Netherlands

Nyström, Erika January 2020 (has links)
Habitat degradation, fragmentation and loss are important factors causing loss in biodiversity and red listed species, and restoring habitats is essential in preventing this. However, there is a limited knowledge of the long term effects of restoration measures. This study focuses on analysing the long term restoration success of restoration measures carried out in a restoration program between the 1980's and early 2000's in locations of acidic fen, buffered fen, dry heather, wet heather, and wet grassland. The aim of the restoration program was to diminish the effects on ecosystems that were influenced by eutrophication, acidification, and dehydration. The locality species composition and Ellenberg values of nitrogen (EVN), moisture (EVM) and pH levels (EVpH) are analysed, by using previous and current restoration success scores from 54 locations in the province of Drenthe in the Netherlands. The dependence of restoration success score and Ellenberg values on change over time, habitat type, restoration method and EVN, EVM and EVpH are analysed. Restoration success depended on habitat type, with wet heather having significantly higher success compared to wet grasslands. The change in score over time, however, did not vary among habitats. Restoration success did not depend on restoration method(s), nor did change in restoration success. Ellenberg values varied among habitat types, and EVM changed significantly over time in dry heather, but was not significantly related to restoration success score. In conclusion, wet heather was shown to be doing quite well, but could benefit from additional restoration. Acidic fen, buffered fen, dry heather, and wet grassland have all shown poor long term restoration effects, indicating an overall need for further restoration measures. The results also highlight the importance of further studies into the effect of long term restorations, especially focused on finding successful restoration methods, and the importance of detailed data gathered in the field.

本論文寫作之問題意識,乃基於對儒學在現代社會角色定位與未來走向之反思。在當代,儒學雖逐漸建立作為學術理論的地位,同時也與一般民眾思想、生活漸行漸遠,這種與傳統儒學化成理想有落差的情況,對在現代仍認同儒學或以儒家自許者,成為一個不得不面對的真實問題。從逆覺體證到理一分殊新釋之理論演變,正在尋求其因應之道。此現代新儒學之內部理論發展,內容是走向日用常行化與廣義道德實踐之建立,理一分殊作為方法架構,亦具有應用在種種不同觀點的普遍意義。 首先,就理一分殊新釋而言,一切文化創造活動都屬分殊,只能「通於」、而不能「同於」理一。良知坎陷的範圍也應擴及逆覺體證的行為實踐領域。包括道德行為在內的一切人類活動,都已是理一在某個時空之具體落實,具有侷限而不再等同於無限,但雖不可等同於無限,卻又通於無限。一切人文活動都可通於理一,但因「通」的型態不同,故定位也各異。逆覺體證是「逆」或「返」於理一之「通」,重點在契接、體悟理一;其他人文活動是「順」或「發」自理一之「通」,重點在承繼或順應理一之動用,成就現實生活中的各種價值創造。既然都是「通」於而非「同」於理一,就不必強分高下而可同時並重。儒家作為成德之學的道德實踐概念內涵,就不僅限於由逆覺所體證而發之於道德行為之狹義的道德實踐,而可涵蓋一切正面價值創造活動,成為一種廣義的道德實踐。 這種廣義的道德實踐,是具有基本道德操守而同時以仁心與生生之精神為終極託付的人生態度,凡認同此態度而不斷從事正面價值創造者,不論是學者、藝術家、科學家等任何職業與身分,都是現代意義下的儒者。從事儒家思想研究工作而又同時具有以上生活態度的現代新儒學,即取得在儒學架構下的正當性與必要性。儒家的理想仍然嚮往與追求聖賢境界,卻不再是作為儒者的唯一條件,這是使逆覺體證由聖賢工夫走向日用常行化的轉向。 就廣義道德實踐的立場,內聖是指以仁心與生生精神為終極託付,外王雖主要指涉政治領域,亦可延伸至以仁心與生生為前提,而從事商業、學術、藝術等活動。這種廣義道德實踐的另一個理論效應,則是基於良知與見聞的辯證關係,以及朱子對人之有限性的警覺,將朱子與象山的先後天修養工夫同時並重,而統合於陽明的良知教之下。廣義的道德實踐是以生生之仁為出發點,有關此普遍人性之內涵,牟宗三先生指出是一種心性情合一之普遍道德主體,並以由本心自定自發律則而具現於行為之動態過程,亦即「實踐上的印證」,說明此道德主體之具體化問題。至於道德意識普遍性之證成的落實問題,則需要劉述先先生參與全球倫理運動的「共識上的印證」作補充。這是藉由存異求同的理一分殊方法,與世界各大宗教文化進行平等的對話,從中所得到的共通於各大傳統之極小式的底限共識,亦即人道與金律,可作為說明落實問題之一種可能途徑。 逆覺體證本質上是從工夫論導出哲學理論之系統。可使儒學在指引效力之外逐漸展現出解釋效力,成為一種可以在學術上掌握與論析的理論系統。理一分殊的方法論為這種走向之延續。理一作為人文學科中的規約原則,有別於經驗科學的歸納(induction),因為歸納的方式是取同略異,理一分殊秉持的是存異求同之精神。筆者即嘗試就如何順成朱子所謂「去兩短,合兩長」,以及內聖外王雙向互動之兩行,作為這種方法論應用的實例。這兩個觀點雖非理一分殊新釋之內容,卻可藉由其方法予以證成,正可說明理一分殊方法的普遍意義。 / Nowadays, the situation of Confucianism is rather dubious. It used to be the guidelines of politics and everyday life in Chinese society. However, Confucianism is now not as influential as it was before. Its practical role has given way to theoretical one. This phenomenon, for many, means the loss of the essence of Confucianism. In my opinion, the prospect of turnaround lies in the development of ni-chüeh-t'i-cheng to the New Interpretation of li-i-fen-shu. The content of this progress can be divided into three: the secularization of moral practice, the wide-ranging creation of values and a formation of methodology. At first, ni-chüeh-t'i-cheng emphasizes the request of being sages while the New Interpretation of li-i-fen-shu focuses on the obedience to rules of law and decorum. As a result, the moral practice of Contemporary Neo-Confucian Philosophy is easy for normal people to abide by. Secondly, the New Interpretation of li-i-fen-shu advocates not so much moral practice as the creation of values. Accordingly, people belonging to every walk of life are regarded as a Neo-Confucian on condition that he or she has faith in jen(humanity) and sheng-sheng(creative creativity). Taken together, these theses indicate that Contemporary Neo-Confucian Philosophy tends to lives of modern people. Finally, ni-chüeh-t'i-cheng is a kind of kung-fu-lun which doubles as a academic theory. Nevertheless, li-i-fen-shu has a facet of methodology. I manage to apply this methodology to two issues in Confucianism: the necessity of ch’u-liang-tuan, ho-liang-ch’ang by Chu-Hsi and the interaction between nei-shen and wai-wang. The significance of li-i-fen-shu will be highlighted if my analysis is justified.
