| 1 | Root Physiological and Morphological Characteristics of Two Rice Cultivars with Different Nitrogen-Use Efficiency显示文摘The variation in nitrogen (N) uptake by rice has been widely studied but differences in rice root morphology that may contribute to this variation are not completely understood. Field and greenhouse experiments were carried out to study N accumulation, root dry weights, total root lengths, root surface areas, and root bleeding rates of two rice cultivars, Elio with low N-use efficiency and Nanguang with high N-use efficiency. Low (1 mmol N L-1) and high (5 mmol N L-1) N applications were established in the greenhouse experiment, and the N rates were 0, 120, and 240 kg ha-1 in the field experiments at Jiangning and Jiangpu farms, Nanjing, China. The results showed that the N accumulation, root dry weight, total root length, and root surface area increased with an increase in N application. At the heading stage, N accumulation in the shoots and roots of Nanguang was greater than that of Elio in the field experiments and that of Elio at 5 mmol N L-1 in the greenhouse experiment. After the heading stage, N accumulation was higher for Nanguang at both 1 and 5 mmol N L-1 in the greenhouse experiment. The total root length and root surface area were significantly different between the two cultivars. Over the range of the fertilizer application rates, the root lengths of Nanguang at Jiangning Farm were 49%-61% greater at booting and 26%-39% greater at heading than those of Elio, and at Jiangpu Farm they were 22%-42% and 26%-38% greater, respectively. Nanguang had a greater root bleeding rate than Elio. It was concluded that the N-use efficiency of the two rice cultivars studied depended to a great extent on the root morphological parameters and root physiological characteristics at different growth stages. | FAN Jian-Bo ZHANG Ya-Li D.

| 2 | Model-Based Integrated Methods for Quantitative Estimation of Soil Salinity from Hyperspectral Remote Sensing Data:A Case Study of Selected South African Soils显示文摘Soil salinization is a land degradation process that leads to reduced agricultural yields. This study investigated the method that can best predict electrical conductivity (EC) in dry soils using individual bands, a normalized difference salinity index (NDSI), partial least squares regression (PLSR), and bagging PLSR. Soil spectral reflectance of dried, ground, and sieved soil samples containing varying amounts of EC was measured using an ASD FieldSpec spectrometer in a darkroom. Predictive models were computed using a training dataset. An independent validation dataset was used to validate the models. The results showed that good predictions could be made based on bagging PLSR using first derivative reflectance (validation R2 = 0.85), PLSR using untransformed reflectance (validation R2 = 0.70), NDSI (validation R2 = 0.65), and the untransformed individual band at 2257 nm (validation R2 = 0.60) predictive models. These suggested the potential of mapping soil salinity using airborne and/or satellite hyperspectral data during dry seasons. | Z. E. MASHIMBYE M. A. CHO J. P. NELL W. P. DE CLERCQ A. VAN NIEKERK D.

| 3 | 项目管理理论及其架构显示文摘一种观点认为缺乏全面的理论是阻碍项目管理被认可为一门管理学科的因素,现存的被系统观点所统治的项目管理理论更多地被视做工程学的分支,而不是管理学。更进一步,现存的理论是建立在大量源自经验证据的假设基础上的,这使得最终产生的理论似乎仅仅是建立在假设基础上的经验证据。这些假设使用了复杂的需要进一步界定的概念,这又使得项目管理理论似乎仅仅是一些定义。在这篇文章中,作者提出一套建立在五个简单的、自然的前提之上的关于项目管理的理论。这些前提不需要假设,所使用的简单的、自然的概念也不需要进一步界定(或者,另外一种情况是概念是由前面的前提得出的)。 | Rodney Turner 杨伟 杨玉武 | 2006 | 项目管理技术2006,4,10: | 17 |

| 9 | Role of surgery in severe ulcerative colitis in the era of medical rescue therapy显示文摘Despite the growing use of medical salvage therapy,colectomy has remained a cornerstone in managing acute severe ulcerative colitis(ASC) both in children and in adults.Colectomy should be regarded as a life saving procedure in ASC,and must be seriously considered in any steroid-refractory patient.However,colectomy is not a cure for the disease but rather the substitution of a large problem with smaller problems,including fecal incontinence,pouchitis,irritable pouch syndrome,cuffitis,anastomotic ulcer and stenosis,missed or de-novo Crohn's disease and,in young females,reduced fecundity.This notion has led to the widespread practice of offering medical salvage therapy before colectomy in most patients without surgical abdomen or toxic megacolon.Medical salvage therapies which have proved effective in the clinical trial setting include cyclosporine,tacrolimus and infliximab,which seem equally effective in the short term.Validated predictive rules can identify a subset of patients who will eventually fail corticosteroid therapy after only 3-5 d of steroid therapy with an accuracy of 85%-95%.This accuracy is sufficiently high for initiat-ing medical therapy,but usually not colectomy,early in the admission without delaying colectomy if required.This approach has reduced the colectomy rate in ASC from 30%-70% in the past to 10%-20% nowadays,and the mortality rate from over 70% in the 1930s to about 1%.In general,restorative proctocolectomy(ileoanal pouch or ileal pouch-anal anastomosis),especially the J-pouch,is preferred over straight pullthrough(ileo-anal) or ileo-rectal anastomosis,which may still be considered in young females concerned about infertility.Colectomy in the acute severe colitis setting,is usually performed in three steps due to the severity of the inflammation,concurrent steroid treatment and the generally reduced clinical condition.The first surgical step involves colectomy and constructing an ileal stoma,the second-constructing the pouch and the third-closing the stoma.This review focuses on the role of surgical treatment in ulcerative colitis in the era of medical rescue therapy. | Bosmat Dayan Dan Turner | 2012 | World Journal of Gastroenterology2012,18,29: | 8 |
| 10 | Carotenoids Particle Formation by Supercritical Fluid Technologies显示文摘Based on the solubility in supercritical CO2,two strategies in which CO2 plays different roles are used to make quercetine and astaxanthin particles by supercritical fluid technologies.The experimental results showed that micronized quercetine particles with mean particle size of 1.0-1.5 μm can be made via solution enhanced dispersion by supercritical fluids(SEDS) process,in which CO2 worked as turbulent anti-solvent;while for astaxanthin,micronized particles with mean particle size of 0.3-0.8 μm were also made successfully by rapid expansion supercritical solution(RESS) process. | 全灿 Johan Carlfors Charlotta Turner | 2009 | Chinese Journal of Chemical Engineering2009,17,2: | 7 |

| 15 | Early chronic obstructive pulmonary disease: Beyond spirometry显示文摘The significant healthcare burden associated with chronic obstructive pulmonary disease(COPD) is driving us to improve our understanding of the natural history of this disease. Historically, the focus has been largely centred on diagnosing and treating individuals with moderate and severe disease. However, it is now recognised that the speed of decline in lung function as measured by forced expiratory volume in 1 s occurs faster in the earlier stages of the disease process. As a result, a clearer understanding of the potential benefits of treatment in early COPD is needed. It is recognised that many patients with COPD remain undiagnosed in the community which has prompted global case-finding initiatives. In this review we discuss the difficulties in diagnosing COPD in its early stages, examine the roleof case-finding and look at the evidence for early intervention with therapeutic agents. There is a growing interest in the phenotypic variation amongst patients with COPD and we explore the role of phenotyping in early COPD and its potential benefits in providing a more individualised approach to COPD management. The majority of patients with COPD are known to die from non-respiratory causes such as cardiovascular disease. The mechanistic link is thought to relate to systemic inflammation, causing us to question whether earlier interventions could have a beneficial impact on the burden of co-morbidities for patients with COPD. | Judith A Brebner Alice M Turner | 2013 | World Journal of Respirology2013,3,3: | 5 |

| 19 | Pancreatitis in patients with pancreas divisum:Imaging features at MRI and MRCP显示文摘AIM:To determine the magnetic resonance cholangiopancreatography(MRCP)and magnetic resonance imaging(MRI)features of pancreatitis with pancreas divisum(PD)and the differences vs pancreatitis without divisum.METHODS:Institutional review board approval was obtained and the informed consent requirement was waived for this HIPAA-compliant study.During one year period,1439 consecutive patients underwent successful MRCP without injection of secretin and abdominal MRI studies for a variety of clinical indications using a 1.5 T magnetic resonance scanner.Two experienced radiologists retrospectively reviewed all the studies in consensus.Disputes were resolved via consultation with a third experienced radiologist.The assessment included presence and the imaging findings of PD,pancreatitis,and distribution of abnormalities.The pancreatitis with divisum constituted the study group while the pancreatitis without divisum served as the control group.MRCP and MRI findings were correlated with final diagnosis.Fisher exact tests and Pearson × 2 tests were performed.RESULTS:Pancreatitis was demonstrated at MRCP and MRI in 173 cases(38 cases with and 135 cases without divisum)among the 1439 consecutive cases.The recurrent acute pancreatitis accounted for 55.26%(21 of 38)in pancreatitis patients associated with PD,which was higher than 6.67%(9 of 135)in the control group,whereas the chronic pancreatitis was a dominant type in the control group(85.19%,115 of 135)when compared to the study group(42.11%,16 of 38)(χ 2 = 40.494,P < 0.0001).In cases of pancreatitis with PD,the dorsal pancreatitis accounted for a much higher percentage than that in pancreatitis without PD(17 of 38,44.74% vs 30 of 135,22.22%)(χ 2 = 7.257,P < 0.05).CONCLUSION:MRCP and MRI can depict the features of pancreatitis associated with divisum.Recurrent acute pancreatitis and isolated dorsal involvement are more common in patients with divisum. | Deng-Bin Wang Jinxing Yu Ann S Fulcher Mary A Turner | 2013 | World Journal of Gastroenterology2013,19,30: | 5 |
| 20 | Comprehensive Utilization of Vanadium-Titanium Magnetite Deposits in China Has Come to a New Level显示文摘There are two production areas for vanadium-titanium magnetite deposits in China:the Panzhihua area in Sichuan Province and the Chengde area in Hebei Province. The Panzhihua vanadium titanomagnetite iron ore deposits are hosted by a mafic-ultramafic intrusive complex,and belong to late magmatic differentiation condensation of crystalline iron deposits.The rock mass is characterized by good differentiation,clear and differentiated facies zones and rhythm.The rock assemblage can be divided into the following rock facies combination:gabbro,gabbro-norite,gabbro troctolite,gabbro-plagioclase,gabbro-eclogite-olivine pyroxenite,and diabase types.The orebodies occur mostly as close-bedded,distributed in the dark facies zone in the bottom layers of the middle or lower part of the stratiform rock mass.The main ore minerals are granular ilmenite,magnetite,ilmenite spar,and magnesium aluminum spinel,with small amounts of pyrrhotite,pyrite and cobalt,nickel and copper sulfide.The ores have siderite and mosaic textures and occur as compact massive,banded and disseminated structures;they consist of TFeO 20%-45%,TiO2 3%-16%,V2O50.15%-0.5%,Cr2O30.1%-0.38%,associated with trace amounts of Cu,Co,Ni,Ga,Mn,P,Se,Te,Sc and Pt group elements. | Hao Ziguo Fei Hongcai Liu Lian Susan Turner | 2013 | Acta Geologica Sinica(English Edition)2013,87,1: | 4 |
