Background： Three experiments were conducted to examine the overall hypothesis that addition of medium chain triglycerides（MCT） and cysteamine hydrochloride（CSH） into the diets of young and growing pigs would stimulate the endogenous somatotropic axis to improve growth and ***： In Experiment 1, weaner pigs were given either a 5 d dietary supplement of 5 % MCT（n = 8） or a control diet（n = 8）. MCT increased the plasma concentration of growth hormone（GH; P ＆lt; 0.05） and the GH secretagogue,ghrelin（P ＆lt; 0.05）. Additionally, the MCT treatment reduced scouring（P ＆lt; 0.05）, maintained villous height in the small intestine（P ＆lt; 0.05） and stabilised daily weight gain（P ＆lt; 0.05）, compared to the controls. Experiment 2compared the effects of 4 levels（0, 1, 3 and 6 % v/v） of MCT supplementation in grower-finisher male pigs, of approximately 35 kg live weight（n = 15 per treatment）. Blood samples taken after 7 wk of treatment showed that the MCT supplementation increased circulating ghrelin（P ＆lt; 0.001）, GH（P ＆lt; 0.01） and insulin（P ＆lt; 0.05）concentrations in a dose-dependent manner. Daily weight gain, feed intake and feed conversion ratio were not affected by the MCT diets. In Experiment 3, 64 female pigs of approximately 60 kg live weight were allocated to one of three dietary treatments： control（n = 20）; 6 % MCT（n = 21）; and 70 mg/kg CSH（n = 21）. After 3 wk of supplementation, the MCT treated pigs had a higher plasma concentration of ghrelin compared to the control and CSH pigs（P ＆lt; 0.05）. Plasma concentrations of GH and weight were not affected by any of the dietary ***： Evidence is provided in Experiment 1 to support the use of dietary MCT supplements, perhaps acting via stimulation of somatotropic endocrine pathways, to minimise weaning-associated disorders such as slowing of growth and diarrhoea. In Experiments 2 and 3, although there was no effect on weight gain or feed conversion ratio in either experiment, MCT and CSH incr

REVIVING CHERMAYEFF’S PATIO HOUSE: A DEEP ENERGY RETROFIT AND RENOVATION OF AN ICONIC MID-CENTURY MODERN HOME

引用

Journal of Green Building 2013年第4期8卷 67-80页

作者： bruce Coldham Coldham&Hartman Architects

Buildings in the mid-twentieth century were conceived within a bubble of expectation of boundless energy, a situation that was short-lived, and a mindset set that is hard to comprehend these days. Nowadays, it is easy to understand that the thermally flimsy products of this era require some dramatic invention-what we often call a “deep energy retrofit” (DER)-and there is an emerging set of standard responses to such envelope enhancement. But some of these buildings have high architectural significance, and deserve a more design-oriented solution than simply wrapping them in an insulative swaddle. This is the story of one such building.

MicroRNAs in nasopharyngeal carcinoma

Chinese Journal of Cancer 2014年第11期33卷 539-544页

MicroRNAs(miRNAs) provide insight into both the biology and clinical behavior of many human cancers, including nasopharyngeal carcinoma(NPC). The dysregulation of miRNAs in NPC results in a variety of tumor-promoting effects. Furthermore, several miRNAs are prognostic markers for NPC. In addition to cellular miRNAs, NPC samples also often contain miRNAs encoded by Epstein-Barr virus, and these miRNAs may impact NPC biology by targeting both cellular and viral genes. Given their numerous putative roles in NPC development and progression, a thorough understanding of the impact of miRNA dysregulation in NPC is expected to shed light on useful biomarkers and therapeutic targets for the clinical management of this disease. In this review, we describe the efforts to date to identify and characterize such miRNAs in the context of NPC.

Amarts on Riesz Spaces

Acta Mathematica Sinica,English Series 2008年第2期24卷 329-342页

作者： Coenraad C.A. LABUSCHAGNE bruce A.wATSON School of Mathematics University of the witwatersrand Private Bag 3 P O wITS 2050 South Africa

The concepts of conditional expectations, martingales and stopping times were extended to the Riesz space context by Kuo, Labuschagne and watson （Discrete time stochastic processes on Riesz spaces, Indag. Math.,15（2004）, 435-451）. Here we extend the definition of an asymptotic martingale （amart） to the Riesz spaces context, and prove that Riesz space amarts can be decomposed into the sum of a martingale and an adapted sequence convergent to zero. Consequently an amart convergence theorem is deduced.

Activation of mitochondrial ATP-sensitive potassium channels delays ischemia-induced cellular uncoupling in rat heart

引用

Acta Pharmacologica Sinica 2004年第1期 24-30页

作者： Iain C bruce China Department of Physiology Faculty of Medicine The University of Hong Kong

AIM: To test the hypothesis that cellular uncoupling induced by myocardial ischemia is mediated by activation of cmitochondrial ATP-sensitive potassium channels (mitoKATP). METHODS: Rat hearts were perfused on a Langendorff apparatus and subjected to 40-min ischemia followed by 30-min reperfusion (I/R). Changes in cellular coupling were monitored by measuring whole-tissue resistance. RESULTS: (1) In hearts subjected to I/R, the onset of uncoupling started at (13.3±1.0) mm of ischemia; (2) Ischemic preconditioning (IPC) delayed the onset of uncoupling until (22.7±1.3) min. Blocking mitoKATP channels with 5-

Assessment of energy release mechanisms contributing to coal burst

引用

International Journal of Mining Science and Technology 2017年第1期27卷 43-47页

作者： Zhang Chengguo Canbulat Ismet Tahmasebinia Faham Hebblewhite bruce School of Mining Engineering UNSw Sydney 2052Australia

Coal burst is a dynamic release of energy within the rock （or coal） mass leading to high velocity expulsion of the broken/failed material into mine openings. This phenomenon has been recognised as one of the most catastrophic failures associated with the coal mining industry, which can often lead to injuries and fatalities of miners as well as significant production losses. This paper aims to examine the mecha- nisms contributing to coal burst occurrence, with an emphasis on the energy release concept. In this study, a numerical modelling study has been conducted to evaluate the roles and contributions of differ- ence energy components. The energy analysis presented in this paper can help to improve the under- standing of energy release mechanisms esoeciallv under Australian conditions.

Phase Transitions of Ferromagnetic Potts Models on the Simple Cubic Lattice

引用

Chinese Physics Letters 2014年第7期31卷 41-45页

作者：王顺谢志远陈靖 bruce Normand 向涛 Institute of Physics Chinese Academy of Sciences Beijing 100190 Department of Physics Renmin University of China Beijing 100872

we investigate the 2- and 3-state ferromagnetic Ports models on the simple cubic lattice using the tensor renorrealization group method with higher-order singular value decomposition （FIOTRG）. HOTRG works in the thermodynamic limit, where we use the Zq symmetry of the model, combined with a new measure for detecting the transition, to improve the accuracy of the critical point for the 2-state model by two orders of magnitude, obtaining Tc = 4.51152469（1）. The 3-state model is far more complex, and we improve the overall understanding of this case by calculating its thermodynamic quantities with high accuracy. Our results verify that the first-order nature of the phase transition and the HOTRG transition temperature benchmarks the most recent Monte Carlo result.
