The Influence of water and catalyst leach process toward propane oxidation on MoVTeNb catalyst
Authors: Widi R K 
Published: December 2019

Abstract
The effect of the water stream to the propane oxidation on diluted MoVTeNb catalyst has been investigated. The present work has elucidated that careful operation of high throughput instrumentation can be used in various beneficial ways to speed up the discovery process of improved catalysts in other forms than enabling efficient trial-and-error testing of compositional variations of a given catalyst system. The result shows that the addition of massive amounts of water to the feed should have a negative influence on the kinetics, as water will compete with all other polar molecules in the system for adsorption sites. This work also investigated the effect of catalyst leach process toward propane oxidation. From the result, it can be described that catalyst leach process tends to reduce the phase of the catalyst that responds to the total oxidation of propane. This work also proposed the reaction network and gave the comparison between the propane oxidation reaction kinetic using leached and un-leached catalyst. The result showed that the activation energy of the acrylic acid formation on the leached catalyst was slightly higher than that of on un-leached catalyst. On the other hand, the activation energy of the carbon dioxide formation on the leached catalyst was much higher than that of on un-leached catalyst. It can be described that the leaching process to the catalyst can reduce the phase of the catalyst responsible for the total oxidation of propane.
Anchored instruction ITS: a novel approach to make learning programming interesting and effective
Authors: Hartanto B , Reye J 
Published: December 2019

Abstract
Learning programming is known to be troublesome to the students in the computer science department. The problem is originated in the students’ inability to understand the logic in developing the program. Many teachers advise the students to practice writing the program to improve the students’ skill. However, many students do not enthusiastically follow this advice due to the unattractive activity in writing the program as well as the lack of help when they have problems in writing the program. In this research, we proposed a system that increases the attractiveness of the program development activity and is able to provide help when the students have problems in it. These goals were performed by integrating an anchored instruction in an Intelligent Tutoring System (ITS). The attractiveness of the anchored instruction and the effectiveness of the Intelligent Tutoring System were analysed using a pre- and post-test, and a survey. From the tests and the survey, we found that the anchored instruction can increase the students’ interest in practicing programming; the Intelligent Tutoring System could help the students in writing the program and improve their knowledge in programming (24.67% improvement). The research showed that anchored instruction Intelligent Tutoring System can be used as an alternative approach to make learning programming interesting and effective.

Authors: Kusumo A H , Hartono M 
Published: December 2019

Abstract
The current study evaluated the academic website using eye tracking and User Experience Questionnaire (UEQ). A total of 46 participants had been recruited for this study but then the data were reduced to 33 participants due to random response errors of an item in UEQ followed by reducing in eye tracker’s data. Eye tracker had a gaze plot (scan path) data and task completion time as time to first view area of interest (AOI) where these data were used to evaluate important gaze plot and whether the provision of information in website had been clearly done. The gaze plot gave insight where important link, information and picture should be put in the website. Furthermore, Kruskal Wallis and Mann Whitney U test were also applied to see the difference between each task which were used to improve sub menu’s name. At the same time, UEQ data showed that only novelty should be improved to be more creative, inventive, leading edge and innovative. Thus, this recommendation provides more input in designing website for academic use.

Authors: Widiasri M , Santoso L P , Siswantoro J 
Published: December 2019

Abstract
One important process in egg production is the sorting process to determine the grade of the egg. The volume and mass of the egg are the factors needed in this sorting process. But the conventional way to measure egg volume and mass can damage egg and takes a long time. This paper proposes a Computer Vision System (CVS) to measure egg volume and mass quickly, accurately, precisely without damaging the egg. The disc method is a method used to calculate the volume of an object with a circular cross-section such as an egg. CVS was designed to calculate the volume using the disc method and calculate the egg mass using density and regression models, based on images captured in real-time or images that have been captured previously. The validation process is carried out using 50 egg samples by comparing results from the proposed method with manual measurements. To compare the time needed by CVS and manual measurement, an average test was used. To test the output accuracy of the volume and mass of egg, relative absolute error, ANOVA test, and correlation test were used. Whereas to test the output precision, the coefficient of variation was used. Based on the results of the testing conducted, CVS in the proposed method successfully measuring the volume and mass of egg quickly, accurately, precisely, without damaging the egg.

Abstract
In this study, Na2CO3 was used as activator to roast and activate high-alumina fly ash (HAFA), and the vacuum roasting technology was used to enhance the activation process of HAFA. The effects of the vacuum conditions on the activation of HAFA roasted using conventional and microwave heating were investigated. It was determined that the reaction time was shortened and the activation effect of HAFA was improved under vacuum conditions; however, the effect of the vacuum conditions on the roasting temperature was negligible. The activation process of HAFA-Na2CO3 mixtures (HAFA/Na2CO3 mass ratio of 1:1) was promoted by conducting conventional and microwave heating experiments under vacuum (−0.04 MPa). The leaching rate of aluminium of 93.00% was reached at the roasting temperature of 900 °C after only 20 min when the HAFA-Na2CO3 mixture was subjected to conventional heating under vacuum, and after 60 min when conventional heating occurred under normal atmospheric pressure. Moreover, the leaching rate of aluminium of 96.00% was reached at the roasting temperature of 700 °C after only 20 min when the HAFA-Na2CO3 mixture underwent microwave heating under vacuum, and after 30 min when microwave heating occurred under normal atmospheric pressure.

Abstract
Role of sucrose in sequential reduction of copper (II) ions is investigated. Copper/copper(I) oxide/copper(II) oxide (Cu/CuO/Cu2O) microspheres are synthesized via hydrothermal method using sucrose as template. Size of microparticles lies in 9–16 μm range. Formation mechanism of spherical architecture is also proposed. Synthesized spheres are used in two major applications: (i) catalyst for degradation of methyl red (MR) and methyl blue (MB) (ii) fuel additive in commercial diesel. The rate constant of degradation of both dyes (MB and MR) is not found equal under similar conditions. Results indicated that increased concentrations of microparticles in diesel significantly affect properties.

Published: December 2019

Abstract
This paper investigates the use of graphite in 2017 Aluminium matrix composite for thermal management systems by analyzing their thermo-elastic behavior. The composite samples were prepared with different graphite contents using powder metallurgy method based on recycled 2017 Aluminium alloy powder. The distribution of graphite particles in the 2017 Aluminium alloy matrix was investigated by a scanning electron microscope (SEM). Sintered densities of the composite samples were examined by a gravimetric method and it is noticed that in the fact of increasing the graphite content decreases the densification of composites which is confirmed by SEM analysis. Thereafter, the obtained samples were analyzed by dilatometry through measuring the coefficient of thermal expansion (CTE), which showed a decrease with the addition of graphite.

Abstract

Purpose
The primary objective was to evaluate the impact of an analgosedation protocol in a cardiac intensive care unit (CICU) on daily doses and costs of analgesic, sedative, and antipsychotic medications.

Methods
We conducted a single-center quasi-experimental study in 363 mechanically ventilated patients admitted to our CICU from March 1, 2011, to April 13, 2013. On March 1, 2012, an analgosedation protocol was implemented. Patients in the pre-implementation group were managed at the cardiologist’s discretion, which consisted of a continuous sedative-hypnotic approach and opioids as needed. Patients in the implementation group were managed using this protocol.

Results
The mean ± S.D. per-patient doses (mg/day) of propofol, lorazepam, and clonazepam decreased with the use of an analgosedation protocol (propofol 132,265.7 ± 12,951 versus 87,980.5 ± 10,564 [p = 0.03]; lorazepam 10.5 ± 7.3 versus 3.3 ± 4.0 [p &lt; 0.001]; clonazepam 9.9 ± 8.3 versus 1.1 ± 0.5 [p = 0.03]). The mean daily cost of propofol and lorazepam also significantly decreased (33.5% reduction in propofol cost [p = 0.03]; 69.0% reduction in lorazepam cost [p &lt; 0.001]). The per-patient dose and cost of fentanyl (mcg/day) declined with analgosedation protocol use (fentanyl 2,274.2 ± 2317.4 versus 1,026.7 ± 981.4 [p &lt; 0.001]; 54.8% decrease in fentanyl cost [p &lt; 0.001]).

Conclusion
The implementation of an analgosedation protocol significantly decreased both the use and cost of propofol, lorazepam, and fentanyl. Further investigation of the clinical impact and cost-effectiveness of a critical care consultation service with implementation of an analgosedation protocol is warranted in the CICU.

Published: December 2019

AbstractBackgroundApolipoprotein B (ApoB), a constituent of lipid particles, is known to increase the risk of cardiovascular diseases. However, the association between ApoB and end-stage renal disease (ESRD) remains to be resolved. Our objective was to determine whether the ApoB concentration has an association with the risk of ESRD.MethodsSerum ApoB, ApoA1, conventional lipid parameters and lipid subfractions were analyzed in 9403 subjects. The hazard ratio (HR) for the risk of ESRD was calculated using tertiles of ApoB concentration.ResultsESRD developed in 110 patients (1.2%) during 10 years of follow-up. Several lipid parameters were compared for their association with the risk of ESRD, of which ApoB was best and its relationship was also independent of other clinical parameters. Individuals in the second and third ApoB tertiles had a higher risk of ESRD than those in the first tertile, with HRs of 1.5 [95% confidence interval (CI) 0.89–2.61] and 2.6 (1.56–4.20), respectively. A high ApoB:ApoA1 ratio was associated with a higher risk of ESRD, but ApoA1 had no independent association. Even after adjusting the competing risk for all-cause death, high ApoB concentrations had an association with the risk of ESRD.ConclusionsHigh ApoB concentration is associated with a higher risk of ESRD, despite adjustment for other lipid and clinical parameters. Accordingly, the monitoring of ApoB may be helpful for the prediction of ESRD.

Abstract

Background
The new European legislation on data protection, namely, the General Data Protection Regulation (GDPR), has introduced comprehensive requirements for the documentation about the processing of personal data as well as informing the data subjects of its use. GDPR's accountability principle requires institutions, projects, and data hubs to document their data processings and demonstrate compliance with the GDPR. In response to this requirement, we see the emergence of commercial data-mapping tools, and institutions creating GDPR data register with such tools. One shortcoming of this approach is the genericity of tools, and their process-based model not capturing the project-based, collaborative nature of data processing in biomedical research.

Findings
We have developed a software tool to allow research institutions to comply with the GDPR accountability requirement and map the sometimes very complex data flows in biomedical research. By analysing the transparency and record-keeping obligations of each GDPR principle, we observe that our tool effectively meets the accountability requirement.

Conclusions
The GDPR is bringing data protection to center stage in research data management, necessitating dedicated tools, personnel, and processes. Our tool, DAISY, is tailored specifically for biomedical research and can help institutions in tackling the documentation challenge brought about by the GDPR. DAISY is made available as a free and open source tool on Github. DAISY is actively being used at the Luxembourg Centre for Systems Biomedicine and the ELIXIR-Luxembourg data hub.
The Reich Military Court and Its Values: Wehrmacht Treatment of Jehovah’s Witness Conscientious Objectors
Authors: Kehoe Thomas J 
Published: December 2019

Abstract
Between 1939 and 1945, the highest Wehrmacht court—the Reichskriegsgericht (RKG)—condemned hundreds of Jehovah’s Witness conscientious objectors to death. Though the law permitted lesser sentences, in the majority of cases judges opted for capital punishment. Debate about their motivations persists. Were they Nazi ideologues? Did Nazi laws constrain their judgements? Or do other factors explain their decisions? This examination of the legal reasoning of RKG jurists suggests that the judges held to a totalizing military value system that aligned with Nazi thinking, but did not derive from it. As opposed to civilian courts such as the Volksgerichte, military priorities guided the RKG. Sentences in both court systems were, however, similar for Witnesses who remained dedicated to their beliefs, as courts meted out the harshest sentences possible.

AbstractBackgroundResistant bipolar disorder is a major mental health problem related to significant disability and overall cost. The aim of the current study was to perform a systematic review of the literature concerning (1) the definition of treatment resistance in bipolar disorder, (2) its clinical and (3) neurobiological correlates, and (4) the evidence-based treatment options for treatment-resistant bipolar disorder and for eventually developing guidelines for the treatment of this conditionMaterials and MethodsThe PRISMA method was used to identify all published papers relevant to the definition of treatment resistance in bipolar disorder and the associated evidence-based treatment options. The MEDLINE was searched to April 22, 2018.ResultsCriteria were developed for the identification of resistance in bipolar disorder concerning all phases. The search of the literature identified all published studies concerning treatment options. The data were classified according to strength, and separate guidelines regarding resistant acute mania, acute bipolar depression, and the maintenance phase were developed.DiscussionThe definition of resistance in bipolar disorder is by itself difficult due to the complexity of the clinical picture, course, and treatment options. The current guidelines are the first, to our knowledge, developed specifically for the treatment of resistant bipolar disorder patients, and they also include an operationalized definition of treatment resistance. They were based on a thorough and deep search of the literature and utilize as much as possible an evidence-based approach.
Asymptotic stabilization for a wave equation with periodic disturbance
Authors: Wei Jing , Feng Hongyinping , Guo Bao-Zhu 
Published: December 2019

Abstract
In this paper, we consider boundary stabilization for a one-dimensional wave equation subject to periodic disturbance. By regarding the periodic signal as a boundary output of a free wave equation, we transform the controlled plant into a coupled wave system. We first design a state observer for the coupled system to estimate the disturbance and the system state simultaneously. An output feedback control is then designed to stabilize the original system. As an application, the result is applied to the stabilization of a wave equation with periodic disturbance suffering in output. Finally, some simulations are presented to validate the theoretical results.
Compactness and Rigidity of λ-Surfaces

Published: December 2019

Abstract
In this paper we develop the compactness theorem for $\lambda $-surface in $\mathbb R^3$ with uniform $\lambda $, genus, and area growth. This theorem can be viewed as a generalization of Colding–Minicozzi’s compactness theorem for self-shrinkers in $\mathbb R^3$. As an application of this compactness theorem, we prove a rigidity theorem for convex $\lambda $-surfaces.

AbstractResilience to restricted availability of drinking water was evaluated with 44 Dorper (DOR; initial age = 3.7 ± 0.34 yr), 42 Katahdin (KAT; 3.9 ± 0.36 yr), and 42 St. Croix (STC; 2.7 ± 0.29 yr) sheep from 46 farms in 4 regions of the USA (Midwest, MW; Northwest, NW; Southeast, SE; central Texas, TX). Ad libitum water intake was determined during 2 wk of period 1, with 75% of this amount offered in 2 wk of period 2 and 50% in 5 wk (i.e., 5 to 9) of period 3. Body weight and DMI in week 2 of period 1 and week 9 of period 3 were analyzed with a mixed effects model. There was a breed × period interaction (P = 0.023) in water intake relative to BW (6.17, 6.69, and 7.19 in period 1 and 3.04%, 3.26%, and 3.36% BW in period 3 for DOR, KAT, and STC, respectively; SEM = 0.219). There were 3-way interactions of breed, region, and period in BW and DMI in g/d (P &lt; 0.010). For STC, BW was greater (P &lt; 0.05) in period 3 vs. 1 for all regions (50.1, 47.6, 42.4, and 45.8 kg in period 1 and 51.9, 49.3, 44.5, and 47.7 kg in period 3), whereas there was only a period difference for DOR from the MW and SE (61.4, 66.0, 64.6, and 59.6 kg in period 1 and 60.6, 66.5, 65.7, and 62.4 kg) and for KAT from TX (50.1, 47.6, 42.4, and 45.8 kg in period 1 and 51.9, 49.3, 44.5, and 47.7 kg in period 3 for MW, NW, SE, and TX, respectively; SEM = 2.57). In accordance, DMI by STC was similar (P &gt; 0.05) between periods for all regions (1.25, 1.17, 1.06, and 1.16 kg/d in period 1 and 1.12, 1.08, 1.02, and 1.02 kg/d in period 3), as was also the case for DOR from MW and SE but not from NW or TX (1.54, 1.50, 1.30, and 1.41 kg/d in period 1 and 1.41, 1.13, 1.25, and 1.18 kg/d in period 3) and KAT from TX though not from the other 3 regions (1.47, 1.52, 1.48, and 1.40 kg/d in period 1 and 1.06, 1.15, 1.30, and 1.33 kg/d in period 3 for MW, NW, SE, and TX, respectively; SEM = 0.061). In conclusion, based on BW and DMI with water intake restricted at 50% of ad libitum consumption by individual animals, STC appeared more consistent in display of high resilience to restricted water availability, although DOR from 2 regions and KAT from 1 also were relatively resilient. The results suggest benefit to breed comparisons of inclusion of animals from multiple areas and that environmental conditions of regions may have disparate effects with different breeds of hair sheep.
