| 1 | Geometry of screw compressor rotors and their tools显示文摘This paper presents a method of general geometrical definitions of screw machine rotors and their manufacturing tools.It describes the details of lobe shape specification,and focuses on a new lobe profile,which yields a larger cross-sectional area and shorter sealing lines resulting in higher delivery rates for the same tip speed.A well proven mathematical model was used to determine the optimum profile,compressor housing size,and compressor ports to achieve the superior compressors. | Nikola STOSIC Ian K.SMITH Ahmed KOVACEVIC Elvedin MUJIC | 2011 | Journal of Zhejiang University-Science A(Applied Physics & Engineering)2011,12,4: | 14 |
| 2 | 饲料中霉菌毒素对家禽免疫机能的危害显示文摘霉菌毒素是由真菌(霉菌)产生的一系列化学性质各异的化合物,是家禽饲料中常见的污染物。对家禽生产造成经济损失的霉菌毒素有:黄曲霉毒素,赭曲霉毒素,单端孢菌毒素,玉米赤霉烯酮和烟曲霉毒素。霉菌毒素的有害影响主要通过四个机制:①降低采食量;②减少营养吸收;③内分泌影响以及;④抑制免疫机能。在这些不同的机制中,霉菌毒素抑制免疫机能对家禽生产造成的经济损失最大。 | Trevor K.Smith | 2008 | 中国家禽2008,30,16: | 8 |
| 3 | 饲料中镰刀菌毒素的毒理协同作用显示文摘霉菌毒素是霉(真)菌产生的有毒代谢物,家畜大量采食后导致的病理综合征称为霉菌毒素中毒。谷物中霉菌的生长及毒素的合成受很多因素影响,其中水分最为重要。产毒真菌一般适于在潮湿、温暖和有氧的条件下生长。因此,水分高的谷物最易受到侵袭。贮藏谷物时,水分含量必... | TREVOR K.SMITH 王冉 杜君松 | 1999 | 国外畜牧科技1999,26,2: | 3 |

| 7 | Minimal conceptual models for tropical cyclone intensification显示文摘We examine a hierarchy of minimal conceptual models for tropical cyclone intensification.These models are framed mostly in terms of axisymmetric balance dynamics.In the first set of models,the heating rate is prescribed in such a way to mimic a deep overturning circulation with convergence in the lower troposphere and divergence in the upper troposphere,characteristic of a region of deep moist convection.In the second set,the heating rate is related explicitly to the latent heat release of ascending air parcels.The release of latent heat markedly reduces the local static stability of ascending air,raising two possibilities in the balance framework.The first possibility is that the effective static stability and the related discriminant in the Eliassen equation for the overturning circulation in saturated air,although small,remains positive so the Eliassen equation is globally elliptic.The second possibility,the more likely one during vortex intensification,is that the effective static stability in saturated air is negative and the Eliassen equation becomes locally hyperbolic.These models help to understand the differences between the early Ooyama models of 1968 and 1969,the Emanuel,1989 model,and the later Emanuel models of 1995,1997 and 2012.They provide insight also into the popular explanation of the WISHE feedback mechanism for tropical cyclone intensification.Some implications for recent work are discussed. | Michael T.Montgomery Roger K.Smith | 2022 | Tropical Cyclone Research and Review2022,11,2: | 1 |
| 8 | 饲料来源的霉菌毒素对畜禽生产性能的影响试验显示文摘据统计,目前世界上至少有25%的谷物被霉菌毒素所污染,尤其是黄曲霉素的污染已成为全球性难题。本试验旨在探讨饲料来源的霉菌毒素对畜禽生产性能的影响和如何采取预防措施,以保证养殖业的安全生产。霉可吸(GMA)是一种葡甘露多聚糖霉菌毒素吸附剂,在受霉菌毒素污染的奶牛、母猪、肉用种鸡日粮中添加0.2%GMA,可明显降低霉菌毒素对奶牛产奶量、血浆球蛋白、血浆尿素;母猪采食量、日增重、饲料利用率、死产率;家禽的产蛋率、蛋壳厚度和早期胚胎死亡率的影响。 | Trevor K.Smith 沈慧乐 | 2012 | 浙江畜牧兽医2012,37,2: | 1 |

| 12 | Application of the rotating-convection paradigm for tropical cyclones to interpreting medicanes:An example显示文摘The rotating-convection paradigm for tropical cyclone behaviour is shown to provide an attractive and consistent framework for interpreting the dynamics of formation and intensification of at least some medicanes.The ideas are illustrated by a case study of the medicane that formed over the eastern Mediterranean in mid-December 2020.This case study is based on analyses of data from the European Centre for Medium Range Weather Forecasts(ECMWF),imagery from the European geostationary meteorological satellite,Meteosat Second Generation,and output from a convection permitting numerical simulation of the event using the United Kingdom(UK)Met Office regional model with the RAL2 physics configuration.Limitations of the currently widely accepted interpretation of medicanes in terms of the so-called Wind-Induced Surface Heat Exchange(WISHE)intensification mechanism are discussed. | Gerard Kilroy Hongyan Zhu Minhee Chang Roger K.Smith | 2022 | Tropical Cyclone Research and Review2022,11,3: | 1 |

| 17 | A solution scan of societal options to reduce transmission and spread of respiratory viruses:SARS-CoV-2 as a case study显示文摘Societal biosecurity–measures built into everyday society to minimize risks from pests and diseases–is an important aspect of managing epidemics and pandemics.We aimed to identify societal options for reducing the transmission and spread of respiratory viruses.We used SARS-CoV-2(severe acute respiratory syndrome coronavirus 2)as a case study to meet the immediate need to manage the COVID-19 pandemic and eventually transition to more normal societal conditions,and to catalog options for managing similar pandemics in the future.We used a‘solution scanning’approach.We read the literature;consulted psychology,public health,medical,and solution scanning experts;crowd-sourced options using social media;and collated comments on a preprint.Here,we present a list of 519 possible measures to reduce SARS-CoV-2 transmission and spread.We provide a long list of options for policymakers and businesses to consider when designing biosecurity plans to combat SARS-CoV-2 and similar pathogens in the future.We also developed an online application to help with this process.We encourage testing of actions,documentation of outcomes,revisions to the current list,and the addition of further options. | William J.Sutherland Nigel G.Taylor David C.Aldridge Philip Martin Catherine Rhodes Gorm Shackelford Simon Beard Haydn Belfield Andrew J.Bladon Cameron Brick Alec P.Christie Andrew P.Dobson Harriet Downey Amelia S.C.Hood Fangyuan Hua Alice C.Hughes Rebecca M.Jarvis Douglas MacFarlane William H.Morgan Anne-ChristineMupepele Stefan J.Marciniak Cassidy Nelson SeánÓhÉigeartaigh Clarissa Rios Rojas Katherine A.Sainsbury Rebecca K.Smith Lalitha S.Sundaram Ann Thornton John Watkins Thomas B.White Kate Willott Silviu O.Petrovan | 2021 | Journal of Biosafety and Biosecurity2021,3,2: | 0 |
| 18 | 霉菌毒素对全球家禽的威胁显示文摘从全球范围来看,家禽饲料的霉菌毒素污染发生率似乎在不断地提高。这对家禽是一个严重的威胁,因为复杂的家禽日粮对霉菌毒素的污染高度易感。因此,此类污染会严重影响家禽的生产性能,由此需要采取适当措施将该损失降低到最小程度。 | 李俊霞 Trevor K.Smith | 2010 | 国外畜牧学(猪与禽)2010,,3: | 0 |
| 19 | 加拿大新斯科舍省Meguma群中脉型金矿床成矿模式显示文摘Meguma群中的脉型金矿床是新斯科舍省南部Meguma地区下古生界变质浊积岩中以多种含金石英脉形式聚集而成的矿床.对Meguma地区30个该类矿床的广泛野外研究(区域填图和详细填图)及室内分析(岩相、液体包裹体、地球化学、同位素等)结果表明,在广泛的镁铁质及长英质岩浆侵位于同时发育有陡倾剪切带的地壳期间产生成矿作用.成矿年龄为370Ma左右(热液脉矿物,^(40)Ar/^(39)Ar法测定).因此,矿化比Aeadian区域性变形作用大约要晚30—40Ma.同他素数据(S、C、O、Sr)表明形成矿脉溶液不仅来自岩浆,其中部分也来自Meguma群的外来变质溶液。因此那种单一的早期岩浆热液源和Meguma群沉积变质岩的变质侧分泌作为矿脉组分来源的成矿模式都是不可取的。 | Daniel J.Kontak Paul K.Smith Robert Kerrich 吴伟成 | 1993 | 国外铀金地质1993,10,4: | 0 |
| 20 | Preliminary age-based life history characteristics of the dogtooth tuna,Gymnosarda unicolor(Ruppell,1838),in the southwest Pacific Ocean显示文摘Dogtooth tuna,Gymnosarda unicolor were sampled off the east coast of Australia(southwest Pacific Ocean)from 2007 to 2012.Ages were determined by examining thin transverse sections of their sagittal otoliths and were based on counts of alternating opaque and translucent zones(annual growth increments).Growth was rapid during the first year of life,after which growth in length was much reduced.Parameters of the constrained von Bertalanffy growth function(fork length-at-age)were L∞=1164.77(mm,FL)and K=0.44 year^(-1).Preliminary estimates of longevity indicate a maximum observed age of at least 20 years.There was a high degree of variation in the observed length and age of sexual maturity for G.unicolor.Despite this variation,the size at 50%maturity for female G.unicolor estimated in this study was 713 mm FL(<2 years of age).The diet of G.unicolor is very broad and covers a range of fish species.The life history characteristics of G.unicolor overall,indicate that this species may be somewhat resilient to fishing.However,reports of localised depletions,in association with heavy targeting by sports fishers,low effective population sizes and patchy recruitment indicate that this species is particularly vulnerable to overfishing. | David J.Welch Adam K.Smith Kyne Krusic-Golub Sandra Erdmann Stephen J.Newman | 2023 | Aquaculture and Fisheries2023,8,3: | 0 |
