| 4 | Kinetics of the Oxidative Dehydrogenation of Isobutane over Cr_2O_3/La_2(CO_3)_3显示文摘The oxidative dehydrogenation (ODH) of isobutane over Cr2o3/La2(CO3)3 has been investi-gated in a low-pressure Kundsen cell reactor,under conditions where the kinetics of the primary reaction steps can be accurately determined .By heating the catalyst at a constant rate from 150-300℃ ,temper-ature fluctuations due to non-equilibrium adsorption are minimized ,The evolved gas profiles show that ODH to isobutene and water is a primary reaction pathway,while carbon dioxide ,which forms from the catalyst during reaction,is the only other product,This CO2 evolution may enhance the activity of the catalyst ,Isobutene formation proceeds with the participation of lattice oxygen from the Cr2O3/La2(CO3)3 catalyst The intrinsic Arrhenius rate constant for the ODH of isobutane is k(s^-1)=10^11.5±2.2exp{-((55±5)-△Hads kJmol^-1)/RT} The small pre-exponential factor is expected for a concerted mechanism and for such a catalys with a small surface area and limited porosity. | Yanping Sun Tracey A.Robson Trevor C.Brown | 2002 | Journal of Natural Gas Chemistry2002，11，1： | 1 |

| 8 | In situ stabilization of arsenic in soil with organoclay,organozeolite,birnessite,goethite and lanthanum-doped magnetic biochar显示文摘Arsenic(As)is a known carcinogen and naturally occurring semi-metal in soils and in the Earth's crust.Contamination of soils and water with As poses a serious threat to millions of people worldwide due to its health hazards and toxicological properties.Hence,devising novel and efficient methods for remediation of contaminated areas has attracted a great deal of interest across the globe.In this study,we investigated the usefulness of synthetic birnessite,goethite,hexadecylpyridinium chloride-modified montmorillonite(HDPC-M),hexadecylpyridinium bromide-modified zeolite(HDPB-Z),and lanthanum(La)-doped magnetic biochar produced from eucalyptus bark(La-Euchar)as adsorbents at 10%dosage for As stabilization in a soil spiked with 1000 mg kg^(-1)As.The effectiveness of the above adsorbents in As immobilization in soil was assessed using single-step extractions with 2 mol L^(-1)HNO_(3)and deionized water,the simplified bioaccessibility extraction test(SBET)method,and sequential extraction with the modified Community Bureau of Reference(BCR)method.Application of the adsorbents shifted the exchangeable fraction of As to more recalcitrant fractions and dramatically reduced the exchangeable fraction by 6%-99%and the extractable amounts with HNO_(3),deionized water,and SBET method by 30%-92%,17%-95%,and 12%-90%,respectively,compared to the unamended control.The immobilizing effects of adsorbents on As decreased in the sequence of birnessite>La-Euchar>goethite>HDPB-Z>HDPC-M.Birnessite exhibited great affinity for As and drastically reduced As extractability by more than 90%in all single extractions.The results revealed that HDPC-M,HDPB-Z,La-Euchar,birnessite,and goethite are promising immobilizing agents for in situ stabilization of As in terrestrial environments. | Saeed BAGHERIFAM Trevor C.BROWN Christopher M.FELLOWS Ravi NAIDU Sridhar KOMARNENI | 2022 | Pedosphere2022，32，5： | 1 |

| 11 | Cryogenic nanosecond and picosecond high average and peak power(HAPP) pump lasers for ultrafast applications显示文摘Using cryogenic laser technology, it is now possible to design and demonstrate lasers that have concomitant high average and peak powers, with near-diffraction-limited beam quality. We refer to these new laser systems as HAPP lasers. In this paper, we review important laser crystal materials properties at cryogenic temperature, with an emphasis on Yb lasers, and discuss the important design considerations, including the laser-induced damage threshold, nonlinear effects and thermal effects. A comprehensive model is presented to describe diode pulsed pumping with arbitrary duration and repetition rate, and is used with the Frantz–Nodvik equation to describe, to first order, the performance of HAPP laser systems. A computer code with representative results is also described. | David C.Brown Sten Tornegrd Joseph Kolis | 2016 | High Power Laser Science and Engineering2016，4，2： | 0 |

| 13 | Unraveling quad fever:Severe hyperthermia after traumatic cervical spinal cord injury显示文摘Purpose:There are many infectious and inflammatory causes for elevated core-body temperatures,though they rarely pass 40℃(104℉).The term'quad fever'is used for extreme hyperpyrexia in the setting of acute cervical spinal cord injuries(SCIs).The traditional methods of treating hyperpyrexia are often ineffective and reported morbidity and mortality rates approach 100%.This study aims to identify the incidence of elevated temperatures in SCIs at our institution and assess the effectiveness of using a non-invasive dry water temperature management system as a treatment modality with mortality.Methods:A retrospective analysis of acute SCI patients requiring surgical intensive care unit admission who experienced fevers≥40℃(104℉)were compared to patients with maximum temperatures<40℃.Patients≥18 years old who sustained an acute traumatic SCI were included in this study.Patients who expired in the emergency department;had a SCI without radiologic abnormality;had neuropraxia;were admitted to any location other than the surgical intensive care unit;or had positive blood cultures were excluded.SAS 9.4 was used to conduct statistical analysis.Results:Over the 9-year study period,35 patients were admitted to the surgical intensive care unit with a verified SCI.Seven patients experienced maximum temperatures of≥40℃.Six of those patients were treated with the dry water temperature management system with an overall mortality of 57.1%in this subgroup.The mortality rate for the 28 patients who experienced a maximum temperature of≤40℃was 21.4%(p=0.16).Conclusion:The diagnosis of quad fever should be considered in patients with cervical SCI in the presence of hyperthermia.In this study,there was no significant difference in mortality between quad fever patients treated with a dry water temperature management system versus SCI patients without quad fever.The early use of a dry water temperature management system appears to decrease the mortality rate of quad fever. | Carlton C.L.Watson Dooniya Shaikh Jody C.DiGiacomo Aaron C.Brown Raina Wallace Shridevi Singh Lisa Szydziaka Sara Cardozo-Stolberg LD.George Angus | 2023 | Chinese Journal of Traumatology2023，26，1： | 0 |
| 14 | 预防泄漏:工程化降低无控制化学品泄漏的危险性显示文摘在药物研究实验室中,自动化纯化系统是仪器的核心部分,它有助于药物的发现。该系统消耗大量的溶剂,以实现对采用的一定量的混合物进行必要的分离。为了给这些系统提供溶剂,通常采用4L溶剂瓶到56L贮液器或小桶,里面往往包含有害液体。因此存在着不少潜在危险,例如火灾,由于意外溢出、泄漏或从溶剂废液瓶中溢出而使接触化学品的科学家和后勤人员受伤。使用通用的、化学惰性的、本质安全的液体传感器安装在二次防漏容器中为废液收集提供了一个相对安全的工作环境。 | Vincent W.CARUSO Edward C.BROWN John P.KAY Michael A.MANCINI James A.WESTRA Philip E.KEYES | 2011 | 生命科学仪器2011，9，5： | 0 |
| 15 | Retinoic acid signaling acts as a rheostat to balance Treg function显示文摘Regulatory T cells(Tregs)promote immune homeostasis by maintaining self-tolerance and regulating inflammatory responses.Under certain inflammatory conditions,Tregs can lose their lineage stability and function.Previous studies have reported that ex vivo exposure to retinoic acid(RA)enhances Treg function and stability.However,it is unknown how RA receptor signaling in Tregs influences these processes in vivo.Herein,we employed mouse models in which RA signaling is silenced by the expression of the dominant negative receptor(DN)RARαin all T cells.Despite the fact that DNRARαconventional T cells are hypofunctional,Tregs had increased CD25 expression,STAT5 pathway activation,mTORC1 signaling and supersuppressor function.Furthermore,DNRARαTregs had increased inhibitory molecule expression,amino acid transporter expression,and metabolic fitness and decreased antiapoptotic proteins.Supersuppressor function was observed when wild-type mice were treated with a pharmacologic pan-RAR antagonist.Unexpectedly,Treg-specific expression of DNRARαresulted in distinct phenotypes,such that a single allele of DNRARαin Tregs heightened their suppressive function,and biallelic expression led to loss of suppression and autoimmunity.The loss of Treg function was not cell intrinsic,as Tregs that developed in a noninflammatory milieu in chimeric mice reconstituted with DNRARαand wild-type bone marrow maintained the enhanced suppressive capacity.Fate mapping suggested that maintaining Treg stability in an inflammatory milieu requires RA signaling.Our findings indicate that RA signaling acts as a rheostat to balance Treg function in inflammatory and noninflammatory conditions in a dose-dependent manner. | Govindarajan Thangavelu Gabriela Andrejeva Sara Bolivar-Wagers Sujeong Jin Michael C.Zaiken Michael Loschi Ethan G.Aguilar Scott N.Furlan Chrysothemis C.Brown Yu-Chi Lee Cameron McDonald Hyman Colby J.Feser Angela Panoskaltsis-Mortari Keli L.Hippen Kelli P.MacDonald William J.Murphy Ivan Maillard Geoffrey R.Hill David H.Munn Robert Zeiser Leslie S.Kean Jeffrey C.Rathmell Hongbo Chi Randolph J.Noelle Bruce R.Blazar | 2022 | Cellular & Molecular Immunology2022，19，7： | 0 |
| 16 | 害虫综合治理中计算机技术开发的研究和推广显示文摘计算机技术已大大促进了害虫治理的发展,不过,随着计算机技术的规模和复杂程度的提高,计算机技术更面向于昆虫治理而并非昆虫学本身了,由于计算机技术需要众多从事昆虫学研究的宝贵的计算机人员,因此重要的是,作为一门科学的昆虫学的发展应是我们强调的重点,这说明在研究和开发领域的所有层次——从面向农户(终端用户)系统的开发到每个昆虫学研究者最后到基金部门都必须率先改变战略,本文讨论这些问题的一个方面。 | Grayson C.Brown 李福林 | 1993 | 国外农学(植物保护)1993，6，1： | 0 |
