Ventilatory responses to inhaled CO2 were measured during continuous negative pressure breathing (CNPB) in awake dogs. End expiratory lung volume (EELV) decreased linearly with pressure level during CNPB (correlation coefficient= 0.81, p<0.005) during air breathing. When CNPB was applied during 5% CO2 inhalation, the decrease in EELV was not significantly different (p<0.5) from that during air breathing. As a result of a lowered EELV, tidal volume (VT) significantly decreased by 22% and... -

As the world struggles to emerge from the Global Financial Crisis the vision of a harmonious framework of global financial regulation seems as distant as ever. Important progress made by international committees such as the Basel Committee on Banking Supervision and the Financial Stability Board notwithstanding, there seem to be increasing signs of unilateral, extraterritorial action by major jurisdictions, including the United States. This paper reviews the framework created by the US financial... -

Akiko Hayashi 환태평양유아교육연구학회 Asia-Pacific journal of research in early childhood education 17 Pages
환태평양유아교육연구학회 Asia-Pacific journal of research in early childhood education 2011, Vol.5 No.2 6 107-123 (17 pages)
This paper explores the Japanese Ministry of Education, Culture, Sports, Science and Technology (MEXT) approach to curriculum policy in early childhood education. The Kindergarten Curriculum Guideline contains few directives or practical suggestions for teachers. The abstractness and indirectness of the MEXT approach to establishing curricular guidelines stands in stark contrast to the much more explicit and directive curriculum guidelines for early childhood education found in China, the US,... -

Fan-Long Jin, Soo-Jin Park 한국탄소학회 Carbon Letters 11 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.2 1 67-77 (11 pages)
Carbon fibers (CFs) have a unique combination of properties which allow them to be widely used as reinforcing materials in advanced polymer composites. The mechanical properties of CF-reinforced polymer composites are governed mainly by the quality of interfacial adhesion between the CFs and the polymer matrix. Surface treatments of CFs are generally carried out to introduce chemical functional groups on the fiber surfaces, which provide the ability to control the surface characteristics of CFs.... -

Purpose: Evaluation and feedback are fundamental components in a residency program. A portfolio assessment system is an appropriate option for making formative assessments, particularly for a family medicine resident whose training includes rotations through various disciplines at multiple locations. However, a paper-based portfolio assessment system has limitations when applied to a clinical environment due to how it is managed and cared. This study assessed the satisfaction and utility of a... -

8 types. 3) These 8 different response patterns could be further classified into those from pressor and depressor neurons. These results demonstrate that some CVNs were identifiable as reticulospinal neurons responding to anti-dromic stimulation and that CVNs operating as depressor neurons as well as pressor neurons exist in the RVLM, both of which are involved with SSR mediation. Therefore, evidence was found that an independent depressor pathway might be involved in the mediation of SSR. -

본 연구는 십이지장내 생리 식염수와 0.01 N HCl을 주입했을때 내측 편도핵의 손상이 췌액 분비와 혈장 secretin 농도에 미치는 영향을 구명하기 위하여 44마리의 수컷 흰쥐를 사용하였다. 그 중 21마리의 흰쥐는 뇌정위 고정장치에 의해 내측 편도핵에 삽입된 전극을 통해 양측성으로 내측 편도핵을 파괴한 내측 편도핵 손상군이고, 나머지 23마리는 편도핵의 손상없이 동일한 수술 조작만을 가한 수술 대조군이다. urethan 마취후에 십이지장 근위부에 위치한 관을 통해 십이지장 내강에 0.01 N HCl 또는 생리 식염수(0.9% NaCl)를... -

Continuous supplementation of mineral nutrients and salicylic acid (SA) as foliar application could improve efficacy in controlling basal stem rot (BSR) disease in oil palm seedling. It is revealed from the results that the highest disease severity index (58.3%) was recorded in T8 treatments at 9 months after inoculation. The best disease control was achieved by T7 treatments (calcium/copper/SA [Ca/Cu/SA]) (5.0%) followed by T1 (5.5%), T5 (5.8%), T3 (8.3%), T6 (8.3%), T4 (13.3%), and T2 (15.8%)... -

Scald, caused by Rhynchosporium secalis has been the major yield-reducing factor for barley production during the last decade. In this study, pathogenic groups of R. secalis were identified to obtain a global picture of the assembly of isolates involved in Syrian populations which is essential for the development of scald-resistant barley cultivars. To identify a number of pathogenic groups, 49 isolates collected over ten years from major barley growing areas in Syria were evaluated on five... -
