No full textClick on the DOI link to access the article (may not be free).This chapter studies the challenge and issue of developing a sound social networking technology (SNT) framework to affect positive student engagement and consequently effective learning. The author aims to enable educational administrators, faculty, and curriculum designers to incorporate and seamlessly integrate SNT in curricula to foster effective and efficient learning. The chapter bases itself on the premise that higher educational institutions failing to develop and integrate social educational technology in their educational systems and policies will face major maintenance and existence issues. Contemporary dynamic technology, diverse learner populations coupled with different types of learning environments, and learning connotations necessitate the need for a robust SNT framework. The author researches the task technology fit (TTF) framework, discusses theories of TAM and ARCS, describes SNT of Twitter and Facebook, and uses a qualitative case study to develop and craft a SNT framework for higher education

Enduro with Methods of Analytical Hierarchy Process ", Studies Program Diploma IV, Merchant Marine Polytechnic Semarang, Supervisor I: A.Agus Tjahjono, M.M,M.Mar.E, Supervisor II: Febria Sujarman, M.T.
Fresh Water Generator is an aircraft that function change sea water into fresh water through the process of evaporation and condensation. So hopefully with this tool installed aboard the ship against dependence can reduce the supply of fresh water from the land. However the fact the real level of high levels of salt in the Fresh Water Generator affects freshwater productivity due to the process of heating and cooling on the evaporator and condensor running slow and caused the decline in the production of the freshwater.
The research was carried out against Fresh Water Generator, Alfa Laval type HW HW80 Aqua on the ship MT. Enduro, one of a fleet owned by PT. Pertamina.This done by the writer in the ship for the past 13 months and 10 days when the author implement the practice of sea. The source of the data used in the preparation of this thesis includes primary data obtained directly from the place of research, as well as secondary data obtained from the literature relating to the title of the thesis. While the types of methods that writers use is qualitative and Analitycal Hierarchy Process, which aims to determine the most influential factor in the causes of increased levels of salt. Source data obtained directly from the boat is interview with the head of the engine room as well as the documentation related to this research.
From this research, factors cause elevated levels of salts on freshwater productivity is to adhere crust on the pipe evaporator and salt crust on the plate evaporator heater and there is dirt in the form of mud on the cooling pipe of condenser. Its effects on the freshwater production is declining. Efforts are being made is to do maintenance on a regular basis, periodic and periodic inspections.

Association of preoperative smoking with the occurrence of postoperative pulmonary complications: A post hoc analysis of an observational study in 29 countries
No full textIntroduction: While smoking has been consistently identified as a significant contributor to postoperative complications, the existing literature on its association with postoperative pulmonary complications remains conflicting.
Aim: We examined the association of preoperative smoking with the occurrence of postoperative pulmonary complications (PPCs).
Methods: Post hoc analysis of an observational study in 146 hospitals across 29 countries. We included patients at increased risk of PPCs, according to the Assess Respiratory Risk in Surgical Patients in Catalonia (ARISCAT) score (≥ 26 points). The primary endpoint was the occurrence of one or more predefined PPCs in the first five postoperative days, including unplanned postoperative need for supplementary oxygen, respiratory failure, unplanned need for invasive ventilation, ARDS, pneumonia and pneumothorax. Secondary endpoints included length of hospital stay and in-hospital mortality. We performed propensity score matching to correct for factors with a known association with postoperative outcomes.
Results: Out of 2632 patients, 531 (20.2 %) patients were smokers and 2102 (79.8 %) non-smokers. At five days after surgery, 101 (19.0 %) smokers versus 404 (19.2) non-smokers had developed one or more PPCs (P = 0.95). Respiratory failure was more common in smokers (5.1 %) than non-smokers (3.0 %) (P = 0.02), while rates of other PPCs like need for supplementary oxygen, invasive ventilation, ARDS, pneumonia, or pneumothorax did not differ between the groups. Length of hospital stay and mortality was not different between groups. Propensity score matching did not change the findings.
Conclusion: The occurrence of PPCs in smokers is not different from non-smokers.

Spinal Microgliosis Due to Resident Microglial Proliferation Is Required for Pain Hypersensitivity after Peripheral Nerve Injury
No full textSummaryPeripheral nerve injury causes neuropathic pain accompanied by remarkable microgliosis in the spinal cord dorsal horn. However, it is still debated whether infiltrated monocytes contribute to injury-induced expansion of the microglial population. Here, we found that spinal microgliosis predominantly results from local proliferation of resident microglia but not from infiltrating monocytes after spinal nerve transection (SNT) by using two genetic mouse models (CCR2RFP/+:CX3CR1GFP/+ and CX3CR1creER/+:R26tdTomato/+ mice) as well as specific staining of microglia and macrophages. Pharmacological inhibition of SNT-induced microglial proliferation correlated with attenuated neuropathic pain hypersensitivities. Microglial proliferation is partially controlled by purinergic and fractalkine signaling, as CX3CR1−/− and P2Y12−/− mice show reduced spinal microglial proliferation and neuropathic pain. These results suggest that local microglial proliferation is the sole source of spinal microgliosis, which represents a potential therapeutic target for neuropathic pain management

Nanowire Transistor Solutions for 5NM and Beyond
No full textIn this paper we present a comprehensive computational study of silicon nanowire transistor (SNT) and a SNM SRAM cell based on advanced design technology co-optimization (DTCO) TCAD tools. Utilizing this methodology, we provide guidelines and solutions for 5 nm and beyond in CMOS technology. At first, drift-diffusion (DD) results are fully calibrated against a Poisson-Schrodinger (PS) solution to calibrate density-gradient quantum corrections, and ensemble Monte Carlo (EMC) simulations to calibrate transport models. The calibrated DD gives us the capability to simulate statistical variability in nanowire transistors of the 5nm node and beyond accurately and efficiently. Various SNT structures are evaluated in terms of device figures of merit, and optimization of SNTs in terms of electrostatics driven performance is carried out. A variability-aware hierarchical compact model approach for SNT is adopted and used for statistical SRAM simulation near the "scaling limit". The scaling of SNTs beyond the 5 nm is also discussed
Association between night-time surgery and occurrence of intraoperative adverse events and postoperative pulmonary complications
No full textBackground: The aim of this post hoc analysis of a large cohort study was to evaluate the association between night-time surgery and the occurrence of intraoperative adverse events (AEs) and postoperative pulmonary complications (PPCs). Methods: LAS VEGAS (Local Assessment of Ventilatory Management During General Anesthesia for Surgery) was a prospective international 1-week study that enrolled adult patients undergoing surgical procedures with general anaesthesia and mechanical ventilation in 146 hospitals across 29 countries. Surgeries were defined as occurring during ‘daytime’ when induction of anaesthesia was between 8:00 AM and 7:59 PM, and as ‘night-time’ when induction was between 8:00 PM and 7:59 AM. Results: Of 9861 included patients, 555 (5.6%) underwent surgery during night-time. The proportion of patients who developed intraoperative AEs was higher during night-time surgery in unmatched (43.6% vs 34.1%; P<0.001) and propensity-matched analyses (43.7% vs 36.8%; P=0.029). PPCs also occurred more often in patients who underwent night-time surgery (14% vs 10%; P=0.004) in an unmatched cohort analysis, although not in a propensity-matched analysis (13.8% vs 11.8%; P=0.39). In a multivariable regression model, including patient characteristics and types of surgery and anaesthesia, night-time surgery was independently associated with a higher incidence of intraoperative AEs (odds ratio: 1.44; 95% confidence interval: 1.09–1.90; P=0.01), but not with a higher incidence of PPCs (odds ratio: 1.32; 95% confidence interval: 0.89–1.90; P=0.15). Conclusions: Intraoperative adverse events and postoperative pulmonary complications occurred more often in patients undergoing night-time surgery. Imbalances in patients’ clinical characteristics, types of surgery, and intraoperative management at night-time partially explained the higher incidence of postoperative pulmonary complications, but not the higher incidence of adverse events.

The Association of Intraoperative driving pressure with postoperative pulmonary complications in open versus closed abdominal surgery patients – a posthoc propensity score–weighted cohort analysis of the LAS VEGAS study
No full textBackground: It is uncertain whether the association of the intraoperative driving pressure (ΔP) with postoperative pulmonary complications (PPCs) depends on the surgical approach during abdominal surgery. Our primary objective was to determine and compare the association of time-weighted average ΔP (ΔPTW) with PPCs. We also tested the association of ΔPTW with intraoperative adverse events.
Methods: Posthoc retrospective propensity score-weighted cohort analysis of patients undergoing open or closed abdominal surgery in the 'Local ASsessment of Ventilatory management during General Anaesthesia for Surgery' (LAS VEGAS) study, that included patients in 146 hospitals across 29 countries. The primary endpoint was a composite of PPCs. The secondary endpoint was a composite of intraoperative adverse events.
Results: The analysis included 1128 and 906 patients undergoing open or closed abdominal surgery, respectively. The PPC rate was 5%. ΔP was lower in open abdominal surgery patients, but ΔPTW was not different between groups. The association of ΔPTW with PPCs was significant in both groups and had a higher risk ratio in closed compared to open abdominal surgery patients (1.11 [95%CI 1.10 to 1.20], P < 0.001 versus 1.05 [95%CI 1.05 to 1.05], P < 0.001; risk difference 0.05 [95%CI 0.04 to 0.06], P < 0.001). The association of ΔPTW with intraoperative adverse events was also significant in both groups but had higher odds ratio in closed compared to open abdominal surgery patients (1.13 [95%CI 1.12- to 1.14], P < 0.001 versus 1.07 [95%CI 1.05 to 1.10], P < 0.001; risk difference 0.05 [95%CI 0.030.07], P < 0.001).
Conclusions: ΔP is associated with PPC and intraoperative adverse events in abdominal surgery, both in open and closed abdominal surgery.
