1利用声发射法和变形率变化法联合测定地应力显示文摘针对葡萄牙南部Neves-Corvo,SA(Somincor)矿区一垂直钻孔钻取的岩芯,利用声发射法(AE法)和变形率变化法(DRA法)联合测定该区域垂直向地应力。试验表明:矿区垂直向地应力呈现随深度增加而增加的趋势,但由于受褶皱、断裂等多种地质因素的影响,随深度的增加,由AE法和DRA法测得的地应力值差别也越大;通过AE和DRA试验曲线确定地应力在较大程度上依赖于对试验曲线中拐点的判断,而这种判断必须结合曲线本身的特点进行。在同一个试样上同时利用AE法和DRA法测定其地应力不仅是可行的,二者还可相互印证,确保了试验数据的可靠性。谢强 邱鹏 余贤斌 Carlos Dinis da Gama 2010煤炭学报2010,35,4:24
2细晶花岗岩的声发射特征试验研究显示文摘对葡萄牙细晶花岗岩同一岩样进行多次单轴压缩循环加卸载试验,监测试验过程中岩样的声发射活动,记录岩样的变形特征,分析总结声发射与变形之间的相互关系。试验表明,葡萄牙细晶花岗岩在高应力状态下凯塞效应明显,所受应力越高,凯塞效应越弱;在判断岩石凯塞点时,因时间–累计声发射能量曲线中拐点明显,比利用时间–累计声发射事件数曲线更容易、更合理;另外,了解试样的变形特征对解释声发射试验结果是一个有益的补充。谢强 Carlos Dinis da Gama 余贤斌 2008岩土工程学报2008,30,5:20
3时间延迟对劈裂试验条件下岩石凯塞效应的影响显示文摘验证了粗晶花岗岩在劈裂试验条件下凯塞效应的存在性。进行了循环加卸载时间间隔分别为2、15d和45d时岩石的声发射试验,讨论了时间延迟对花岗岩凯塞效应的影响。研究结果表明,前期荷载越接近极限强度,岩石的凯塞效应越不明显;凯塞效应随再次加载时间延迟的增加而削弱,在对花岗岩的声发射试验中观察到15d以后岩石的凯塞效应仍然很显著,45d后凯塞效应基本消失。文中同时对试件与加载设备之间的接触状态对声发射试验结果的影响作了初步的定性分析。谢强 余贤斌 Carlos Dinis da Gama 2010岩土力学2010,31,1:9
4Comparative stability analyses of traditional and selective room-and-pillar mining techniques for sub-horizontal tungsten veins显示文摘The stability and productivity concerning a modification on the traditional room and pillar for a new selective technique at the Portuguese Panasqueira Mine have been described.The traditional room-and-pillar stoping uses 5.0-m wide rooms with 3.0 m×3.0 m pillars,while the selective room-and-pillar mining technique consists in stoping with rooms of 4.0 m wide and pillars of 4 m×4 m with a subsequent selective cutting of the quartz veins at the mid pillar of approximately 0.5 m high,to obtain a pillar section with an area of 3.0 m×3.0 m.The stability and productivity analyses indicate that the selective technique obtains smaller average pillar safety factor,more rock mass displacement,more extraction and selectivity ratios,and ore grade improvement,compared with the traditional technique.These results show that the selective technique is also more convenient.This proposed selective room-and-pillar mining technique is applicable to any sub-horizontal narrow quartz veins with wolfram,gold,etc.such as the famous La Rinconada gold mine in the Peruvian Andes.Vidal Felix Navarro Torres Carlos Dinis da Gama Matilde Costa e Silva Paula Falcao Neves Qiang Xie 2011International Journal of Minerals,Metallurgy and Materials2011,18,1:7
5Grain Size Effect on the Martensite Formation in a High-Manganese TWIP Steel by the Rietveld Method显示文摘The aim of the present work was to study the effect of austenite grain size (AGS) on the martensite formation in a high-manganese twinning-induced plasticity (TWIP) steel. The results of a quantitative microstructural characterization of the steel by the whole X-ray pattern fitting Rietveld software, materials analysis using diffraction (MAUD), indicated that the volume fraction of α bcc-martensite increases with increasing AGS. However, the value of the stacking fault probability (P sf ) does not show a large variation for samples with different values of AGS under water-quenching conditions.G. Dini A. Najafizadeh S.M.

6Microglial exosomes in retinal neuroinflammation: focus in glaucoma显示文摘Glaucoma is a leading cause of irreversible blindness, expected to affect 140 million people worldwide by the year 2040. The pathophysiology of glaucoma involves retinal ganglion cell loss, optic nerve atrophy and cupping of the optic disk, culminating in visual field loss(Boia et al., 2020). Glaucoma is a multifactorial disease in which increased intraocular pressure is the main risk factor.Ines Dinis Aires Ana Raquel Santiago 2021Neural Regeneration Research2021,16,9:3

8OsSCE1 Encoding SUMO E2-Conjugating Enzyme Involves in Drought Stress Response of Oryza sativa显示文摘Small ubiquitin-like modifier(SUMO)-conjugating enzymes are involved in post-translational regulatory processes in eukaryotes, including the conjugation of SUMO peptides to protein substrate(SUMOylation). SUMOylation plays an important role in improving plant tolerance to abiotic stress such as salt, drought, heat and cold. Herein, we reported the isolation of OsSCE1(LOC_Os10 g39120) gene encoding a SUMO-conjugating enzyme from rice(Oryza sativa cv. Nipponbare) and its functional validation in response to drought stress. The E2 enzyme, Os SCE1, is one of three key enzymes involved in the conjugation of SUMO to its target proteins. Activated SUMO is transferred to the cysteine of an E2 enzyme and then to the target lysine residue of the substrate, with or without the help of an E3 SUMO ligase. Expression of OsSCE1 was strongly induced by polyethylene glycol 6000(PEG6000) treatment, which suggested OsSCE1 may be involved in the drought stress response. Overexpression of OsSCE1(OsSCE1-OX) in Nipponbare reduced the tolerance to drought stress. Conversely, the drought tolerance was slightly improved by the knockdown of OsSCE1(OsSCE1-KD). These results were further supported by measurement of proline content in OsSCE1-OX and OsSCE1-KD transgenic lines under induced drought stress, which showed OsSCE1-KD transgenic lines accumulated higher proline content than the wild type, whereas OsSCE1-OX line had lower proline content than the wild type. These findings suggested OsSCE1 may play a role as a negative regulator in response to drought stress in rice.Dini NURDIANI Dwi WIDYAJAYANTIE Satya NUGROHO 2018Rice science2018,25,2:2

12Thermo-magnetic analysis of thick-walled spherical pressure vessels made of functionally graded materials显示文摘This study presents an analytical solution of thermal and mechanical displacements, strains, and stresses for a thick-walled rotating spherical pressure vessel made of functionally graded materials (FGMs). The pressure vessel is subject to axisymmetric mechanical and thermal loadings within a uniform magnetic field. The material properties of the FGM are considered as the power-law distribution along the thickness. Navier’s equation, which is a second-order ordinary differential equation, is derived from the mechanical equilibrium equation with the consideration of the thermal stresses and the Lorentz force resulting from the magnetic field. The distributions of the displacement, strains, and stresses are determined by the exact solution to Navier’s equation. Numerical results clarify the influence of the thermal loading, magnetic field, non-homogeneity constant, internal pressure, and angular velocity on the magneto-thermo-elastic response of the functionally graded spherical vessel. It is observed that these parameters have remarkable effects on the distributions of radial displacement, radial and circumferential strains, and radial and circumferential stresses.M. A.

13Biomarkers of hypoxic-ischemic encephalopathy:a systematic review显示文摘Background Current diagnostic criteria for hypoxic–ischemic encephalopathy in the early hours lack objective measurement tools.Therefore,this systematic review aims to identify putative molecules that can be used in diagnosis in daily clinical practice(PROSPERO ID:CRD42021272610).Data sources Searches were performed in PubMed,Web of Science,and Science Direct databases until November 2020.English original papers analyzing samples from newborns>36 weeks that met at least two American College of Obstetricians and Gynecologists diagnostic criteria and/or imaging evidence of cerebral damage were included.Bias was assessed by the Newcastle–Ottawa Scale.The search and data extraction were verified by two authors separately.Results From 373 papers,30 met the inclusion criteria.Data from samples collected in the first 72 hours were extracted,and increased serum levels of neuron-specific enolase and S100-calcium-binding protein-B were associated with a worse prognosis in newborns that suffered an episode of perinatal asphyxia.In addition,the levels of glial fibrillary acidic protein,ubiquitin carboxyl terminal hydrolase isozyme-L1,glutamic pyruvic transaminase-2,lactate,and glucose were elevated in newborns diagnosed with hypoxic–ischemic encephalopathy.Moreover,pathway analysis revealed insulin-like growth factor signaling and alanine,aspartate and glutamate metabolism to be involved in the early molecular response to insult.Conclusions Neuron-specific enolase and S100-calcium-binding protein-B are potential biomarkers,since they are correlated with an unfavorable outcome of hypoxic-ischemic encephalopathy newborns.However,more studies are required to determine the sensitivity and specificity of this approach to be validated for clinical practice.Ines Caramelo Margarida Coelho Miguel Rosado Carla M.P.Cardoso Alexandra Dinis Carlos B.Duarte Mario Graos Bruno Manadas 2023World Journal of Pediatrics2023,19,6:2

15Neutrophile-to-lymphocyte,lymphocyte-to-monocyte,and platelet-tolymphocyte ratios as prognostic and response biomarkers for resectable locally advanced gastric cancer显示文摘BACKGROUND Perioperative fluorouracil plus leucovorin,oxaliplatin,and docetaxel(FLOT)improves prognosis in locally advanced gastric cancer(LAGC).Neutrophil-to-lymphocyte(NLR),lymphocyte-tomonocyte(LMR),and platelet-to-lymphocyte(PLR)ratios are prognostic biomarkers but not predictive factors.AIM To assess blood ratios’(NLR,LMR and PLR)potential predictive response to FLOT and survival outcomes in resectable LAGC patients.METHODS This was a multicentric retrospective study investigating the clinical potential of NLR,LMR,and PLR in resectable LAGC patients,treated with at least one preoperative FLOT cycle,from 12 Portuguese hospitals.Means were compared through non-parametric Mann-Whitney tests.Receiver operating characteristic curve analysis defined the cut-off values as:High PLR>141 for progression and>144 for mortality;high LMR>3.56 for T stage regression(TSR).Poisson and Cox regression models the calculated relative risks/hazard ratios,using NLR,pathologic complete response,TSR,and tumor regression grade(TRG)as independent variables,and overall survival(OS)as the dependent variable.RESULTS This study included 295 patients(mean age,63.7 years;59.7% males).NLR was correlated with survival time(r=0.143,P=0.014).PLR was associated with systemic progression during FLOT(P=0.022)and mortality(P=0.013),with high PLR patients having a 2.2-times higher risk of progression[95% confidence interval(CI):0.89-5.26]and 1.5-times higher risk of mortality(95%CI:0.92-2.55).LMR was associated with TSR,and high LMR patients had a 1.4-times higher risk of achieving TSR(95%CI:1.01-1.99).OS benefit was found with TSR(P=0.015)and partial/complete TRG(P<0.001).Patients without TSR and with no evidence of pathological response had 2.1-times(95%CI:1.14-3.96)and 2.8-times(95%CI:1.6-5)higher risk of death.CONCLUSION Higher NLR is correlated with longer survival time.High LMR patients have a higher risk of decreasing T stage,whereas high PLR patients have higher odds of progressing under FLOT and dying.Patients with TSR and a pathological response have better OS and lower risk of dying.Tiago Cruz Tomás Ines Eiriz Marina Vitorino Rodrigo Vicente Joao Gramaca Alicia Guadalupe Oliveira Paulo Luz Mafalda Baleiras Ana Sofia Spencer Luísa Leal Costa Patrícia Liu Joana Mendonca Magno Dinis Teresa Padrao Marisol Correia Goncalo Atalaia Michelle Silva Teresa Fiúza 2022World Journal of Gastrointestinal Oncology2022,14,7:2
