自含CO2气流中选择脱除H2S作为一种减小设备和降低操作费用的手段已变得普遍地热衷起来了，一种选择性吸收设计功能已被补加入到胺法净化过程的模拟程序中，即TSWEET，在MEA接触时间大约是0．4秒时，此程序得出的结果与选择性吸收数据严格地一致，程序计算也与在11磅／寸2（表压），每板停留时间2秒下操作的deA吸收塔中测出的通过40％CO2的数据相一致，一个用15％wt MdeA接近2米直径的吸收塔也被用来作比较，计算的气相中的H2S良好地在数据的离差之中，此时计算的CO2通过量约高出10％，过程模拟程序精确地描绘了包括全部过程变数影响的选择性吸收过程。

地震效应与地震发生地的地质特性密切相关,会加强该地区的地表运动,尤其是软土地区。加强的程度与共振频率相关,可通过水平与垂直谱比法(H/V谱比法)测量地震噪声从而估算共振频率。本文设计了一种低成本用户友好型数据采集系统(Geophonino-3D),用于记录三分量地震噪声。可开发的系统由信号调节电路和安装有SD Shield(用于存储数据)的Arduino Due组成。本设备首先在实验室中对其实验灵敏度、内部噪声稳定性、通道一致性进行了测试,评估了其是否适用于H/V谱比法。随后,通过在阿利坎特省(西班牙东南部)8个土壤特性不同的场地记录地震噪声,进行了实验验证。根据比较商用地震记录仪测出的功率谱密度和H/V峰值,评估了所开发数据采集系统的性能。所得结果表明本数据采集系统适用于应用H/V谱比法记录地震噪声。Geophonino-3D采用开源和开放硬件系统,部件价格远低于其他商用设备,对于资金短缺的研究团队来说,这是明显的进步。

通常用于地震勘探的商用数据采集系统都是一些很昂贵的设备。本文中,我们开发了一种低成本的数据采集系统(Geophonino),用来记录来自垂直地震检波器的地震信号。该信号首先通过INA155仪表放大器,这个放大器适用于诸如地震噪声这样的低振幅信号,以及一个基于MAX7404开关电容滤波器的反混叠滤波器。然后,放大和滤波后的信号经过Arduino Due数字化和处理并写入SD存储卡中。将Geophonino设置为连续写入,其中采样频率、振幅增益和寄存时间可由用户定义。完整的原型是一个开源和开放硬件的系统。我们已经把写入的信号与从不同的商用数据采集系统和不同种类的地震检波器获得的信号进行了比较测试。得到的结果显示被测试的测量值之间具有良好的相关性,表明可以将Geophonino作为低成本的地震数据采集替代系统。

World journal of Cardiovascular Diseases 2019年第8期9卷 545-552页

OBjECTIVES: In recent years, the percentage of heart transplantation (HT) with short/medium-term assistance devices has increased. This study aims at analyzing primary graft failure and in-hospital mortality according to the type of care. MATERIAL AND METHODS: From january 2013 to december?2017 all patients undergoing urgent HT with circulatory/ventricular assistance?were retrospectively and consecutively recruited. Combined transplants, retransplantations and pediatric transplants were excluded. The sample was divided in 10 groups according to the type of shot/medium term assistance devices. RESULTS: A total of 53 patients were recruited, 79% men, average age 49 ± 13 years. 26 patients (51%) had mechanical ventilation at the time of the HT. primary graft failure occurred in 20 patients (38.5%), whilst it was more frequent in patients assisted with ECMO (8 patients in group 1 (45%) and 7 in group 2 (54%), p 0.5). 14 deaths (27%) were registered, whereas a higher mortality was observed in the group assisted with ECMO (6 patients in group 1 (34%) and 4 in group 2 (31%), p 0.6). Mortality was 17% in the group of non-urgent Levitronix. CONCLUSIONS: despite not showing statistical significance due to the low number of patients in some subgroups, hospital?mortality was high in HT patients with circulatory assistance. A trend towards a higher incidence of primary graft failure and mortality in patients assisted with ECMO was observed. The direct implantation of a centrifugal pump as a bridge to urgent transplantation could identify a subgroup with a better prognosis.

Bright,coherent soft X-ray radiation is essential to a variety of applications in fundamental research and life *** date,a high photon flux in this spectral region can only be delivered by synchrotrons,free-electron lasers or high-order harmonic generation sources,which are driven by kHz-class repetition rate lasers with very high peak ***,we establish a novel route toward powerful and easy-to-use SXR sources by presenting a compact experimentin which nonlinear pulse self-compression to the few-cycle regime is combined with phase-matched high-orderharmonic generation in a single,helium-illed antiresonant hollow-core *** enables the first 100 kHz-classrepetition rate,table-top soft X-ray source that delivers an application-relevant flux of 2.8×10^6 photon s^-1 eV^-1 around 300 *** fibre integration of temporal pulse self-compression(leading to the formation of the necessarystrong-field waveforms)and pressure-controlled phase matching will allow compact,high-repetition-rate lasertechnology,including commercially available systems,to drive simple and cost-effective,coherent high-flux softX-ray sources.
