Analysis of the in-plane shear behaviour of FRP reinforced hollow brick masonry walls
Gabor, A.,Ferrier, E.,Jacquelin, E.,Hamelin, P. Techno-Press 2005 Structural Engineering and Mechanics, An Int'l Jou Vol.19 No.3
This paper presents an experimental as well as a numerical analysis of the in-plane shear behaviour of hollow, $870{\times}840{\times}100mm$ masonry walls, externally strengthened with FRP composites. The experimental approach is devoted to the evaluation of the effectiveness of different composite strengthening configurations and the methodology consists in the diagonal compression of masonry walls. The numerical study assesses the stress and strain state distribution in the unreinforced and strengthened panels using a commercial finite element code. The effect of FRP reinforcement on the masonry behaviour and the capability of modelling to forecast a representative failure mode of the unreinforced and reinforced masonry walls is investigated.

Detailed assessment of scale insect (Hemiptera: Coccoidea) faunas on islands may help predict impacts of invasive ants (Hymenoptera: Formicidae) and informoptions for theirmanagement, including biological control.Mutualism between scale insects and the invasive ant Anoplolepis gracilipes on Christmas Island, Indian Ocean, threatens the conservation of the island's endemic land crab fauna, alters rainforest structure and composition, and disrupts ecosystem processes. Diversity and endemism of the scale insect fauna were assessed through broad survey across rainforest, targeted search on endemic plant species, and inspection of ornamental and horticultural plants in settled areas. Emphasis was placed on honeydew-producing species that sustain ant supercolonies and detection of endemic scale insects that could be non-target species in a biological control programme for honeydew-producing scale insects. Origins of the fauna were inferred using scale insect databases and interception records at Ports-of-Entry for the United States and Korea. Twenty-eight scale insect species in seven families are identified for the island. Four honeydew-producing species, the lac scale Tachardina aurantiaca (Kerriidae) and three soft scale species (Coccidae), are abundant in rainforest and tended by ants. No endemic species were found. Compositionally, the scale insect fauna resembles that of many other tropical islands: almost all species are biogeographically widespread, host-plant generalists, and routinely intercepted in humanmediated dispersal pathways. The likely source bioregion is Sundaland where 27 of the 28 species on the island have been recorded andwhich has been the major pathway for movement of plant material to the island for over a century.

Pulvinaria urbicola Cockerell, a pulvinariine soft scale (Hemiptera: Coccidae), is a broad host-plant generalist, produces honeydew and is commonly tended by ants, including the invasive yellow crazy ant Anoplolepis gracilipes Smith and big-headed ant Pheidole megacephala (Fabricius). Pu. urbicola is implicated in dieback of forest dominated by Pisonia grandis (Nyctaginaceae) on many Indo-Pacific islands. Here we report detection of Pu. urbicola on Christmas Island (Indian Ocean), describe the potential impacts of the association of this trophobiontwith introduced ants, and briefly outline biosecurity and management issues. On Christmas Island, Pu. urbicola represents a threat to stands of Pi. grandis, potentially threatens the dominant forest tree Pi. umbellifera, and could exacerbate supercolony formation and impacts of the yellow crazy ant.

Two papaya (Carica papaya L.) seedlings growing in one planting hole often results in angular or non-vertical growth of the trees. Data on trunk angularity, or leaning, (deviation from the vertical line of reference) and white peach scale, Pseudaulacaspis pentagona Targioni-Tozzetti (Hemiptera: Diaspididae), densities on paired papaya trees were collected approximately 1 year after infestation of a papaya field was discovered. Paired trees showed a significantly higher degree of leaning than single trees. White peach scale densities were significantly higher on tree trunks with a greater departure from vertical in paired comparisons. Therefore,paired tree planting practices may facilitate the development of economic infestations of white peach scale populations in papaya orchards.

This paper aims to examine how transnational interaction has been depicted through theories of socialist realism via Hungarian movie ‘State Department Store’ <Állami Áruház> (1953) and through ‘Juche realism’ via North Korean movie ‘My Favorite Young Man’ <마음에 드는 청년> (1989). The comparative analysis explains how main characteristics of core theories have been reflected on screen. Furthermore, the research method points at two key local specifications, notably (1) the occupation of the protagonists and (2) the location-based narratives. Nevertheless, the study does not focus only on the general similarities, but the major part goes beyond this dimension in order to highlight the discrepancies between the two theories and their film implications. Despite the commonly shared ideologies along with similar contents and forms, there are significant contrasts between the movies on theme approaches and symbology. Therefore, the paper describes how (1) the relation between protagonist and community, (2) the portrait of the antagonist and (3) the image of romance have been visualized from various aspects in the two analyzed works. In conclusion, the chosen movies will be helpful tools to understand the cultural structure and mechanism of these modern totalitarian systems. Moreover, the goal of the study is to illustrate how the related symbols, motives and political messages have been screened from different perspectives, regardless of the similar theoretical frameworks.

<P><B>Abstract</B></P> <P>By coupling a sample pretreatment technique of sample clean up and enrichment power with capillary electrophoresis (CE) of high-performance separation, the task of analyzing trace analytes in a complex matrix such as a biological sample can be carried out successfully with ease. This review aims for providing an overview of strategies to couple sample pretreatment techniques with capillary and related microscale (e.g., microchip) electrophoresis, practically adoptable in an automatic manner, without requiring serious modification of existing instruments to install sophisticated interfaces. In-line sample pretreatment techniques based on liquid phase microextraction performed before sample injection and on-line sample preconcentration techniques performed during or after sample injection are discussed with emphasis on the applicability to samples of high conductivity, commonly encountered for biological samples. An overview of the recent developments in microfluidic immobilized enzymatic microreactors which fit excellently to microchip CE is also given.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Recent advances and major trends in sample pretreatment for capillary electrophoresis are summarized. </LI> <LI> In-line and on-line sample pretreatment techniques are discussed with emphasis on biological samples. </LI> <LI> We provide an overview of strategies to couple sample pretreatment techniques with capillary and microchip electrophoresis. </LI> </UL> </P>
헝가리 영화 ‘국가 백화점’< Allami Aruhaz >(1953)과 북한 영화 <마음에 드는 청년>(1989)을 통해서 본 사회주의 리얼리즘과 주체 리얼리즘의 국가적 상호 작용

이 논문에서는 사회주의 국가 헝가리의 사회주의 리얼리즘과 북한의 주체 리얼리즘을 통한 초 국가적 상호 작용을 헝가리 영화 ‘국가 백화점’ < Allami Aruhaz > (1953)과 북한 영화’마음에 드는 청년’ (1989)으로 비교하고자한다. 연구 방법은 영화에서 이 이론들이 어떻게 표현 되었는가에 대한 두가지 주요 사항, (1) 주요등장인물의 직업, (2) 장소에 기반한 내러티브. 이 두 가지 핵심 요소를 통해 선전의 방법과 이론이 어떻게 영화에 반영되었는지 예시한다. 그럼에도 불구하고 이 연구는 영화들의 보편적 유사성뿐만 아니라 이론과 실습간의 주요 이분법에 초점을 맞춘다. 비슷한 형태, 내용과 흔히 공유되는 이데올로기에도 불구하고 주제 접근과 상징에 상당한 대조가 있다. 따라서 이 탐구는 분석한 영화들에서 (1) 주인공과 지역사회의 관계, (2) 적대자의 묘사와 (3) 로맨스 이미지를 다양한 관점에서 설명하고자 한다. 결과적으로 선택된 영화는 이러한 현대적 전체주의 체제의 문화 시스템과 메커니즘을 이해하도록 도움이되는 도구가 될 것이다. 더욱이 이 논문의 목표는 유사한 이론적 기반, 내용과 형태에 관계없이 주요 상징, 동기와 정치적 메시지가 어떻게 다른지 보여주기 위한 것이다.
