Background: Avoiding primary C-section is the safest and most effective way of decreasing C-section rates. We analyzed circumstances and decisions made among pregnant women without history of C-section and cephalic single fetus (group B), who ended up having a Cesarean birth, to identify opportunities that may optimize the decisions about delivery. Methodology: We evaluated the clinical histories of pregnant women from group B who completed their pregnancies in the Hospital Universitario de Santander (Bucaramanga, Colombia) during 2013. We evaluated the decision moments from admission until birth, including the registry of the reasons for having a C-section, compliance of all the criteria to support the decision and its appropriateness, and how adequate were the procedures done during the induction or augmentation of labor. Results: We evaluated 1320 histories;666 (55.7%) ended by C-Section. In 59.8% of the histories, we identified at least one decision that could have been addressed differently to optimize the delivery type and, potentially, avoid ending in a Cesarean birth. The most frequent opportunities arise due to a lack of clarity in the record of the reason for performing the C-section (70.1%), and inadequate use of labor induction in the patients that had to end their gestation (38.5%). Conclusion: In the Hospital Universitario de Santander during 2013, despite observing a meaningful subregistry of the indication to perform a C-section, we found that in one out of every two patients there are opportunities of improvement in the registry and attention to reduce the high incidence of C-sections in the institution. This analysis allowed us to create a checklist to fill out before making the final decision of performing a Cesarean birth.

BACKGROUND Infliximab original has changed the natural history of inflammatory bowel diseases(IBD) over the past two decades. However, the recent expiration of its patent has allowed the entry of the first Infliximab biosimilar into the European and Spanish markets. Currently switching drugs data in IBD are limited. AIM To compare the efficacy of infliximab biosimilar, CT-P13, against infliximab original, analyzing the loss of response of both at the 12 mo follow-up in patients with *** An observational study of two cohorts has been conducted. One retrospective cohort that included patients with IBD treated with Infliximab original, and a prospective cohort of patients who were switching from infliximab original to infliximab biosimilar(CT-P13). We had analyzed the overall efficacy and loss of efficacy in patients in remission at the end of one year after treatment with the original drug compared to the results of the year of treatment with the ***98 patients(CD 67, CU 31) were included in both cohorts. The overall efficacy for infliximab original per year of treatment was 71% vs 68.2% for infliximab biosimilar(P = 0.80). The loss of overall efficacy at 12 mo for infliximab original was 6.6% vs 14.5% for infliximab biosimilar(P = 0.806). The loss of efficacy in patients who were in basal remission was 16.3% for infliximab original vs 27.1% for infliximab biosimilar. Adverse events were 9.2% for infliximab original vs 11.2% for infliximab biosimilar. CONClUSION The overall efficacy and loss of treatment response with infliximab biosimilar(CT-P13) is similar to that observed with infliximab original in patients who were switching at the 12 mo follow-up. There is no difference in the rate of adverse events.

Different experiments in high speed turbomachines require expensive and sophisticated infrastructure to implement their impulsion and reach high regimes. In developed countries, this can be achieved by using aeroderivative gas turbines or DC motors of about 400 HP. This paper presents an experimental system designed and built with the intention of performing behavior studies in test turbomachinery. The proposed installation uses compressed air as driving fluid, which allows the turbomachinery to reach high rotational speeds where very important phenomena occur. An analysis is carried out considering the rotational speed behavior of an internal combustion engine turbocharger of the Perkins series when it is driven by pressures ranging from 4.2 kg/cm2 to zero. Additionally, another experiment couples an automotive electrical generator with the turbine to observe the system operation when a load is applied. The behavior of the pressure is analyzed when it is in function of the time of air discharge that goes from a compressed air storage tank to the turbocharger for its impulsion. This is an experimental system that can be designed and constructed economically within the bounds of any public university.

为研究隧道锚(tunnel-type anchor,简称TTA)锚岩接触面对动荷载影响的敏感性,寻求一种适用于散索鞍至锚碇缆索处的减振装置。首先,利用有限差分软件建立隧道锚数值模型,监测并分析锚岩接触面共9个测点的速度位移响应;其次,利用滚珠丝杠构件的位移转换放大原理,提出一种适用于前锚室处的惯质黏性阻尼器;最后,利用能量耗散守恒方法,模拟并检验安装该阻尼器后隧道锚的减振效果。结果表明:在动荷载作用下,锚塞体两底角部位测点响应明显大于顶部测点,中部锚岩接触面位移增长较前部与后部更为迅速;隧道锚受低幅值动荷载影响更为明显,动力系数约为1.3,随着荷载幅值的增加,动荷载对于隧道锚的影响会减弱;振动前期较为剧烈,加载0~1 s内剪应变增量增幅明显,后期增量基本不变;设置阻尼器后,锚岩接触面速度位移响应减小,位移减小幅度接近20%,速度响应在1 s内基本衰减至0;阻尼器的减振效果与荷载幅值有关,锚塞体处于中低载荷时,设置阻尼器所带来的减振效果最好,减小效果可以达到24%。

作者： José luis Castillo Sequera José raúl Fernández del Castillo Diez león Gonzalez Sotos Department of Computer Science University of Alcala Madrid Spain.

In this paper, we show a clustering method supported on evolutionary algorithms with the paradigm of linear genetic programming. “The Straight-line Programs (slp)”, which uses a data structure which will be useful to represent collections of documents. This data structure can be seen as a linear representation of programs, as well as representations in the form of graphs. It has been used as a theoretical model in Computer Algebra, and our purpose is to reuse it in a completely different context. In this case, we apply it to the field of grouping library collections through evolutionary algorithms. We show its efficiency with experimental data we got from traditional library collections.

Currently, 15% of the total Hungarian population is affected by either the elevated arsenic or ammonium concentration of drinking water, and 8% is affected by both compounds. The break-point chlorination is a well-known method for ammonium removal, however, during the ammonium-removal process carcinogenic and mutagenic by-products （e.g., THM （trihalogenmethane） and AOX （absorbable organically bound halogens）） may be formed. In order to remove these harmful organic by-products, activated carbon adsorption has to be applied in the technology. The break-point chlorine dose is capable of oxidizing the As3＋ to As5＋. The oxidized form of arsenic can be easily converted to solid phase by adding coagulant （Fe（Ⅲ） or AI（Ⅲ） salt） to the water, and the formed iron/aluminium flocs can be removed by simple rapid sand filtration. laboratory experiments were performed with raw water from two Hungarian settlements, where the water originated from a deep confined aquifer. In the studied settlements, six wells were in operation, and the supplied drinking water contained ammonium above the maximum allowable concentration, and the arsenic content was around the 10 μg/l standard value. It was found that higher chlorine dose （- 10 Cl2：NH4-N） was needed to achieve the breakpoint than the theoretical value （7.6）. The amount of by-products was also measured during the experiments. The AOX concentrations were significantly higher （21.6 μg/l to 143μg/l） in all cases than the THM concentrations （9-18 μg/l）. The needed coagulant doses were also studied in order to achieve the required arsenic concentrations. Fe（Ⅲ） coagulant was applied in all cases, and it was found that 1-1.5 mg/l Fe（Ⅲ） dose was sufficient to achieve 2-5 μg/l arsenic concentration in the treated water. Based on the results, it can be stated that the breakpoint chlorination combined with Fe（Ⅲ） coagulation is a potential technology to achieve the required ammonium and arsenic concentration at the studied settlements.

以‘蛇龙珠’葡萄果实为试材,通过测定其基本理化指标,筛选茉莉酸甲酯(methyljasmonate,MeJA)类物质最适浓度,同时结合顶空固相微萃取-气相色谱-质谱联用技术及酶联免疫吸附试验分析MeJA类物质响应的挥发性关键代谢物及关键酶活性,探究采前MeJA类物质处理对‘蛇龙珠’葡萄果实品质及脂氧合酶(lipoxygenase,lOX)代谢途径中绿叶挥发物的影响。结果表明,与对照组相比,0.1 mmol/l MeJA和5 mmol/l二氢茉莉酸甲酯处理可显著提高‘蛇龙珠’葡萄果实百粒质量、总糖质量浓度、可溶性固形物质量分数、pH值、总酚及总花色苷含量,在采收期时分别提高了10.24%、27.83%、28.24%、4.80%、77.63%、85.29%和9.15%、24.01%、24.41%、8.30%、69.21%、71.57%,果实可滴定酸质量浓度分别降低40.0%及30.24%,果实品质得到显著提高和改善。此浓度处理后,‘蛇龙珠’葡萄果实C6类化合物含量明显提高,更加突出其果实香气的典型性。同时,lOX代谢途径中各个关键酶活性与代谢产物之间具有显著相关性,说明较适浓度的MeJA类物质处理对‘蛇龙珠’葡萄果实中绿叶挥发物的积累具有积极作用。
