Published: August 2019

Abstract
The energy wasted by the propeller of vessel can be gained as benefit by converting it using turbine as the source of electrical energy. The electrical energy can be used as the main energy source of fisherman vessel. The method in this research is redesigning the fisherman vessel combined with savonius turbine to obtain the correct dimension. Vessel dimension is built within Loa = 30.71 m; B = 7.67 m; H = 3.5 m; T = 2.2 m. From those dimensions can be obtained the coefficient between the propeller into the pitch 0.8 m, with the turbine diameter 0.5 m and the position of the turbine 0.1 m from the propeller. Savonius turbine captures electrical energy that produced by the low fluid flow that comes out from the propeller rotation, and will be converted by the generator inside the turbine to become energy. The power produced by the rotation of 1.31 rpm of the turbine is 25.689 kilowatt. It is enough to supply the engine generator with the power of 20.1 kilowatt from the power that produced by the turbine as big as 25.689 kilowatt to lighting the fisherman vessel. This technology can be applied massively to the fishermen vessel as renewable energy.

Abstract
The CPDVA (Cantilever Piezoelectric Double Vibration Absorber) is a mechanism that combines the working principles of DVA and energy harvesting to reduce vibration while generating electrical energy. The working principle of CPDVA uses two masses as an absorber of the vibration system ie main absorber mass and piezoelectric mass. The CPDVA mechamism is designed to get the vibration reduction value at the first natural frequency (36.544rad/s) of system. The simulation results show the optimum value can be achieved if the design of CPDVA mechanism using piezoelctric as much as 4000 pieces. Because, by using 4000 piezoelectric on the CPDVA mechanism, the highest reduction value and electrical power can be achieved.

Published: August 2019

AbstractIn this research, the cellulose-based hydrogels were obtained from the water hyacinth fibers (WHFs) with aids of borax as a chemical cross-linker. The chemical treatment on WHFs, confirmed by Fourier transform infrared (FT-IR) analysis and thermogravimetric analysis (TGA), exhibited the reduction of hemicellulose and lignin. The treated cellulose fibers were dissolved in the mixed solution of NaOH/urea prior to mixing with borax at the cellulose/borax weight ratio of 1/0, 1/0.5 and 1/1 to prepare cellulose-based hydrogels. The effect of borax contents on the properties of cellulose-based hydrogels was investigated. The results showed that the swelling ratio and equilibrium water content of the obtained hydrogels were similar with increasing a borax content.

Abstract
Adsorption of surfactants is widely used for surface modification of different materials. Using of the mixtures of the surfactants in many cases is more attractive compared with single surfactants, however composition of mixed adsorption layers at solid surface was not sufficiently studied yet. In this work, the mutual effect of anionic and nonionic surfactants on the composition of the mixed adsorption layer on the surface of activated carbon (AC) was studied. Sodium hexadecyl sulphate (SHS) and oxyethylated octylphenol Triton X100 (TX-100) were used as anionic and nonionic surfactants, respectively. Mixed SHS/TX-100 systems have been studied over a concentration range of 0.1-8.0 mmol/L and the molar fractions of SHS in the mixtures were within 0.2-0.8. It was shown that the adsorption isotherms of SHS or TX-100 surfactants at AC could be describe by the Langmuir equation. For surfactants mixtures at low equilibrium concentrations, it was found that adsorption of SHS increases when TX-100 is present in the solution. This might be explained by the decreasing of electrostatic interactions between the head groups of SHS molecules in the mixed adsorption layers due to incorporation of the molecules of the nonionic surfactant. At higher total surfactant concentrations, SDS adsorbed at AC surface is replaced by TX-100 molecules and as result the nonionic surfactants is preferentially adsorbed on AC.

Authors: Lowaton Allenn C. , Bañez Lemuel Fil L. 
Published: August 2019

Abstract
To apply radio frequency circuits, nanoscale CMOS technologies are greatly used but this consequence to a thinner gate oxide and silicided drain/source. With this, the electrostatic discharge (ESD) robustness of RF circuits will be much more degraded. Therefore, there is a need for an ESD protection circuit design in RF circuits against ESD damages. In this paper, the proposed ESD protection circuit is presented with concept based silicon-controlled rectifier (SCR) device, two diodes, PMOS transistor and an inductor to efficiently provide protection for radio-frequency (RF) circuits from ESD damages in nanoscale CMOS process. The concept based SCR device is aided with an inductor to provide efficient ESD path discharge to the SCR device. Moreover, the inductor is used to resonate out the parasitic capacitance generated by the ESD protection circuit at the preferred frequency. In addition, the proposed ESD protection circuit is implemented to a low noise amplifier (LNA) at 60-GHz frequency within an efficient area. Furthermore, the ESD protection circuit is simulated to achieve over 2-kV human body model ESD robustness with good RF performances on LNA in 65-nm CMOS technology.

Abstract

Aims
Cumulative consumption of alcohol and variations of alcohol intake by age are unknown in chronic pancreatitis (CP) patients in North America. This study summarizes the lifetime drinking history (LDH) by physician attribution of alcohol etiology, smoking status and sex in persons with CP.

Methods
We analyzed data on 193 CP participants who completed the LDH questionnaire in the North American Pancreatitis Continuation and Validation Study (NAPS2-CV). We collected data on frequency of drinking and drinks per drinking day for each drinking phase of their lives. We examined differences in total number of alcoholic drinks and weight of ethanol consumed by physician’s assessment of CP etiology, sex and smoking status. We also compared intensity of drinking in 20, 30 and 40s by timing of CP diagnosis.

Results
Persons diagnosed with alcoholic CP consumed median of 34,488 drinks (interquartile range 18,240–75,024) prior to diagnosis of CP, which occurred earlier than in persons with CP of other etiology (47 vs. 52 years). Cumulative drinking was greater in male vs. female patients. Male CP patients with a diagnosis of CP before the age of 45 drank more intensely in their 20s as compared to those with later onset of disease. Current smoking was prevalent (67%) among those diagnosed with alcoholic CP. Twenty-eight percent of patients without physician attribution of alcohol etiology reported drinking heavily in the past.

Conclusions
Lifetime cumulative consumption of alcohol and prevalence of current smoking are high in persons diagnosed with alcoholic pancreatitis. Intense drinking in early years is associated with earlier manifestation of the disease.

Abstract
Management of locally advanced head and neck squamous cell carcinoma (HNSCC) requires a multi-prong approach comprising surgery, radiation and/or chemotherapy, yet outcomes are limited. This is largely due to a paucity of biomarkers that can predict response to specific treatment modalities. Here, we evaluated TGFβ3 protein levels in extracellular vesicles (EVs) released by HNSCC cells as a predictor for response to chemoradiation therapy (CRT). To this end, specific EV-fractions were isolated from cell lines or HNSCC patient plasma, and TGFβ3 protein was quantified. In patients treated with CRT, TGFβ3 levels were found to be significantly higher in plasma EV-fractions or non-responders compared with responders. High levels of TGFβ3 levels in Annexin V-EVs were associated with the worst progression-free survival. In vitro experiments demonstrated that TGFβ3 silencing sensitized HNSCC cells to cytotoxic therapies, and this phenotype could be rescued by treatment with exogenous. In addition, specific EV-fractions shed by cisplatin-resistant cells were sufficient to transfer the resistant phenotype to sensitive cells through activation of TGFβ-signaling pathway. Therefore, our data show that TGFβ3 transmitted through EV plays a significant role in response to cytotoxic therapy, which can be exploited as a potential biomarker for CRT response in HNSCC patients treated with curative intent.

Abstract

Background
Immunocompromised adults are at .increased risk of herpes zoster (HZ) infection and related complications. We aimed to assess the incidence of hospital-attended HZ (ie, seen in hospital or emergency department) in immunocompromised populations and compare it to immunocompetent populations.

Methods
We calculated incidence rates (IRs) of hospital-attended HZ in Ontario, Canada, between 1 April 2002 and 31 August 2016 in adults ≥18 years of age categorized as immunocompromised or immunocompetent. We repeated these analyses by type of immunocompromising condition and provided incidence rate ratios (IRRs) comparing to immunocompetent adults. We also calculated IRs and IRRs of HZ complications by immunocompromised status.

Results
There were 135 206 incident cases of hospital-attended HZ during the study period. Immunocompromised adults accounted for 13% of these cases despite representing 3% of the population. The risk of hospital-attended HZ was higher for immunocompromised adults compared with immunocompetent adults (IRR, 2.9 [95% confidence interval {CI}, 2.9–3.0]) and ranged across type of immunocompromising conditions, from 2.6 (95% CI, 2.6–2.7) in those with a solid tumor malignancy to 12.3 (95% CI, 11.3–13.2) in those who had undergone hematopoietic stem cell transplant. The risk of any HZ complication was higher in immunocompromised adults (IRR, 3.6 [95% CI, 3.5–3.7]) and highest for disseminated zoster (IRR, 32.8 [95% CI, 27.8–38.6]).

Conclusions
The risk of hospital-attended HZ and related complications was higher in immunocompromised populations compared with immunocompetent populations. Our findings underscore the high-risk nature of this population and the potential benefits that may be realized through HZ vaccination.

Abstract

Aims
Atherosclerotic plaque development has been associated with wall shear stress (WSS). However, the multidirectionality of blood flow, and thus of WSS, is rarely taken into account. The purpose of this study was to comprehensively compare five metrics that describe (multidirectional) WSS behaviour and assess how WSS multidirectionality affects coronary plaque initiation and progression.

Methods and results
Adult familial hypercholesterolaemic pigs (n = 10) that were fed a high-fat diet, underwent imaging of the three main coronary arteries at three-time points [3 (T1), 9 (T2), and 10–12 (T3) months]. Three-dimensional geometry of the arterial lumen, in combination with local flow velocity measurements, was used to calculate WSS at T1 and T2. For analysis, arteries were divided into 3 mm/45° sectors (n = 3648). Changes in wall thickness and final plaque composition were assessed with near-infrared spectroscopy–intravascular ultrasound, optical coherence tomography imaging, and histology. Both in pigs with advanced and mild disease, the highest plaque progression rate was exclusively found at low time-averaged WSS (TAWSS) or high multidirectional WSS regions at both T1 and T2. However, the eventually largest plaque growth was located in regions with initial low TAWSS or high multidirectional WSS that, over time, became exposed to high TAWSS or low multidirectional WSS at T2. Besides plaque size, also the presence of vulnerable plaque components at the last time point was related to low and multidirectional WSS. Almost all WSS metrics had good predictive values for the development of plaque (47–50%) and advanced fibrous cap atheroma (FCA) development (59–61%).

Conclusion
This study demonstrates that low and multidirectional WSS promote both initiation and progression of coronary atherosclerotic plaques. The high-predictive values of the multidirectional WSS metrics for FCA development indicate their potential as an additional clinical marker for the vulnerable disease.

Abstract
Pacemakers, implantable cardiac defibrillators, and cardiac resynchronization therapy devices are potentially life-saving treatments for a number of cardiac conditions, but are not without risk. Most concerning is the risk of a cardiac implantable electronic device (CIED) infection, which is associated with significant morbidity, increased hospitalizations, reduced survival, and increased healthcare costs. Recommended preventive strategies such as administration of intravenous antibiotics before implantation are well recognized. Uncertainties have remained about the role of various preventive, diagnostic, and treatment measures such as skin antiseptics, pocket antibiotic solutions, anti-bacterial envelopes, prolonged antibiotics post-implantation, and others. Guidance on whether to use novel device alternatives expected to be less prone to infections and novel oral anticoagulants is also limited, as are definitions on minimum quality requirements for centres and operators and volumes. Moreover, an international consensus document on management of CIED infections is lacking. The recognition of these issues, the dissemination of results from important randomized trials focusing on prevention of CIED infections, and observed divergences in managing device-related infections as found in an European Heart Rhythm Association worldwide survey, provided a strong incentive for a 2019 International State-of-the-art Consensus document on risk assessment, prevention, diagnosis, and treatment of CIED infections.
Does the modelling of the pectus bar affect its stability? Rationale for using a short flat bar

Abstract

OBJECTIVES
Although the Nuss procedure for pectus excavatum is still associated with a non-negligible risk of postoperative bar displacement, the potential effects of the length and shape of the bar on its corrective ability and stability have not been sufficiently studied. The aim of this study was to determine how the modelling of the pectus bar affects its stability and whether an alternative configuration of the implant can improve clinical success.

METHODS
Simulated implantation of bars with different shapes and sizes in a computational model was carried out. A 250 N sternal force was applied to the bars, and the resulting forces and moments on the fixation points were identified. Afterwards, a clinical trial was carried out in a group of patients with pectus excavatum, some of whom received long inverted U-shaped bars and some of whom received implants designed from the computational results.

RESULTS
When U-shaped bars were tested, the sternal force generated unbalanced horizontal reaction forces (16 vs 61 N) and large reaction moments at the ends of the bar, conferring the tendency to slide and to rotate, respectively. No lateral or rotational destabilizing forces occurred in the case of a flat bar. Cosmetic outcomes, postoperative times and hospital stays were similar in both clinical groups. However, 2 cases (2/15) of bar flipping occurred in patients who received the conventional bar.

CONCLUSIONS
The shape of the bar is a determinant of its stability. A flat, shorter pectus bar provides adequate correction of the deformity with less tendency for bar displacement in the repair of pectus excavatum.

AbstractOBJECTIVESFew reports on the outcomes of patients treated for Stanford type A acute aortic intramural haematoma (TAAIMH) and retrograde thrombosed type A acute aortic dissection exist. This study aimed to evaluate their long-term results and predictors of adverse outcomes.METHODSWe retrospectively analysed 40 patients with TAAIMH and retrograde thrombosed type A acute aortic dissection. All patients underwent urgent surgery on presentation of life-threatening complications. Before discharge, 18 patients underwent open aortic surgery, and 22 were treated with medical therapy alone. Clinical features of these patients and image appearances were reviewed, and the relationship with overall survival, aortic events, and aortic death was investigated.RESULTSThe in-hospital mortality rate was 4.5% (1 patient) with medical therapy alone and 11.1% (2 patients) with surgical intervention. No patient with initial medical therapy required urgent surgery for life-threatening complications beyond 3 days of admission. The overall survival and aortic death-free survival rates at 1, 5 and 10 years were 85.0%, 72.5% and 59.8% and 90.0%, 81.6% and 77.1%, respectively. TAAIMH associated with penetrating aortic ulcer (PAU) was a risk factor of aortic events (P = 0.020) and significantly influenced aortic death-free survival (P = 0.003).CONCLUSIONSUrgent surgery for complicated TAAIMH and retrograde thrombosed type A acute aortic dissection patients and initial medical therapy for uncomplicated patients show favourable long-term survival rates. TAAIMH is frequently associated with PAU; PAU enlargement is common. Although PAU can remain stable for years, it is a strong predictor of poor prognosis. For optimal long-term results, surgical repair is recommended for TAAIMH associated with PAU.
Incorporating transnational labour: Migration rent, combined relocation, and offshore production networks in Malaysia
Authors: Bastide Loïs 
Published: August 2019

AbstractThe article explores the interactions between transnational labour migration, multinational corporations’ (MNCs) location strategies, and public policies in the context of contemporary Malaysia. My main hypothesis is that the country’s position in global production networks is dependent on the presence of a large pool of foreign workers. To demonstrate this relationship, I develop the concept of ‘migration rent’ in order to account for the specific characteristics of migrant labour in Malaysia. By showing that this rent allows the optimisation of labour, as a production factor, beyond the sole issue of labour costs, the concept allows an explanation for why foreign direct investment does not move to lower-wage countries. By allowing and organising the recruitment of foreign workers on a large scale, the government has shaped territories where both capital and labour can be relocated to achieve effective production factor combinations. To understand this process, I articulate the concept of ‘combined relocation’, which describes transnational investment strategies where both capital and labour are moved to a third country—here Malaysia—under the former’s command. In so doing, the paper thus adds to the literature on MNCs’ spatial strategies, on transnational labour migration, and on Malaysia’s political economy.
Matter power spectrum: from Ly α forest to CMB scales

Published: August 2019

ABSTRACT
We present a new compilation of inferences of the linear 3D matter power spectrum at redshift $z\, {=}\, 0$ from a variety of probes spanning several orders of magnitude in physical scale and in cosmic history. We develop a new lower noise method for performing this inference from the latest Ly α forest 1D power spectrum data. We also include cosmic microwave background (CMB) temperature and polarization power spectra and lensing reconstruction data, the cosmic shear two-point correlation function, and the clustering of luminous red galaxies. We provide a Dockerized Jupyter notebook housing the fairly complex dependences for producing the plot of these data, with the hope that groups in the future can help add to it. Overall, we find qualitative agreement between the independent measurements considered here and the standard ΛCDM cosmological model fit to the Planck data.
