Introduction: Laryngoscopic intubation is an insertion of endotracheal tube into the trachea for maintenance of airway during general anesthesia. Smooth intubation requires attenuation of pressor responses and maintenance of baseline hemodynamic stability. The primary outcome of this study is to compare intravenous fentanyl and lidocaine as an anesthetics adjuvant on attenuation of hemodynamic pressor responses to Laryngoscopic intubation in elective surgical adult patients. Methods: This prospective cohort study recruits 114 patients who underwent elective surgery under general anesthesia with laryngoscopy and endotracheal tube intubation. The study was conducted from January 1, 2018 to March 30, 2018. Systemic random sampling technique was used to select the study participants. Those patients that received intravenous fentanyl 2 micrograms per kilogram three minutes before intubation as an anesthetics adjuvant are considered as Fentanyl-group (group F). The Lidocaine-group (group L) was those patients who receive 2% intravenous lidocaine 1.5 milligrams per kilogram three minutes before intubation as anesthetics adjuvant. Hemodynamic parameters (heart rate and blood pressure) and other variables were documented starting from 3 minutes before intubation to 5 minutes after intubation. Results: The mean heart rate at first minute after intubation was significantly lower in fentanyl group (98.91 ± 15.6 beats per minute (bpm)) compared to lidocaine (107 ± 15.45 bpm), t (112) = 2.8, p = 0.006. Systolic blood pressure was also significantly lower in fentanyl group (141.9 ± 18.9 millimeters of mercury (mmHg)) compared to lidocaine (150 ± 18.098 mmHg), t (112) = 2.45, p = 0.016 at first minute after intubation. At third minute after intubation, heart rate was significantly lower in fentanyl group compared to lidocaine, t (112), p = 0.037. No difference was in heart rate and blood pressure among the group at 5th minute after intubation (p > 0.05). Conclusion and Recommendati

Climate change is one environmental threat that poses great challenges to the future development prospects of Ethiopia. The study used the statistically downscaled daily data in 30-years intervals from the second generation of the Earth System Model (CanESM2) under two Representative Concentration Pathways (RCPs): RCP 4.5 and RCP 8.5 for three future time slices;near-term (2010-2039), mid-century (2040-2069) and end-century (2071-2099) were generated. The observed data of maximum and minimum temperature and precipitation are a good simulation with the modeled data during the calibration and validation periods using the correlation coefficient (R2), the Nash-Sutcliffe efficiency (NSE), and the Root Mean Square Error (RMSE). The projected annual minimum and maximum temperatures are expected to increase by 0.091°C, 0.517°C, and 0.73°C and 0.072°C, 0.245°C, and 0.358°C in the 2020s, 2050s, and 2080s under the intermediate scenario, respectively. Under RCP8.5, the annual minimum and maximum temperatures are expected to increase by 0.192°C, 0.409°C, and 0.708°C, 0.402°C, 4.352°C, and 8.750°C in the 2020s, 2050s, and 2080s, respectively. Besides, the precipitation is expected to increase under intermediate and high emission scenarios by 1.314%, 7.643%, and 12.239%, and 1.269%, 10.316% and 26.298% in the 2020s, 2050s, and 2080s, respectively. Temperature and precipitation are projected to increase in total amounts under all-time slices and emissions pathways. In both emission scenarios, the greatest changes in maximum temperature, minimum temperature, and precipitation are predicted by the end of the century. This implies climate smart actions in development policies and activities need to consider locally downscale expected climatic changes.

多标准决策分析是建设工程管理领域的主要研究任务之一。在建设过程中,不同阶段、不同利益相关者需要做各种各样的决策,包括建设选址决策、建设材料和装配结构的选择、工程计划的实施、项目全过程的预算和监理。预制工厂厂址的选择是关系到项目成败的关键决策。然而,于预制工厂厂址选择标准方面的研究却非常有限。本文主要研究预制工厂厂址的选择问题。首先,通过对大量文献的分析得到了一系列厂址选择标准,其次采用TODIM方法来评价可供选择的厂址,接下来应用模糊TODIM方法来避免决策者的主观偏见,在模糊TODIM方面中采用了三角模糊数表示语言变量。再次,设计实施了MATLAB仿真来实现TODIM和模糊TODIM方法,仿真结果表明了两种方法结果的一致性。接着通过敏感性分析验证了两种方面的合理性。最后,比较了两种方法的结果并进行了讨论。T ODIM和模糊TODIM方法被证明是评价预制工厂选址的有效方法,可以辅助管理人员进行重要的投资决策。
