AbstractDifferent adipokines secreted from adipose tissue, exert a range of physiological
effects. The aim of present systematic review and meta-analysis was to
critically investigate the consequence of bariatric surgery on circulating
adipokines, that is, adiponectin, leptin, visfatin, resistin, plasminogen
activator inhibitor, and chemerin. After systematically checking the following
electronic databases: ISI web of Science, Scopus and PubMed without limitation
in time and language up to February 2019, a pool based on a random effect model
was established. Eighty-five eligible studies were entered for quantitative
analysis. Our meta-analysis revealed that circulating adiponectin increased
significantly after bariatric surgery [Standardized mean difference
(SMD)=1.401, 95% CI: 1.101, 1.701, p<0.001]; whilst
leptin (SMD=–2.178, 95% CI: –2.433,
–1.923, p<0.001), PAI-1 (–14.928 ng/ml
95% CI: –21.794, –8.063, p<0.001), and chemerin
(–50.238 ng/ml 95% CI: –85.708,
–14.768, p<0.001) decreased. However, serum visfatin
(2.05 ng/ml, 95% CI: –5.07, 9.17,
p=0.573) and resistin (–2.080 ng/ml, 95%
CI: –5.352, 1.192, p=0.21) were unchanged. In conclusion,
bariatric surgery is associated with a reduction in specific adipokines
including leptin, chemerin, and PAI-1, whereas adiponectin is raised,
adaptations that could be indicative of improved fat mass and function.

Published: April 2020

ZUSAMMENFASSUNGFür einen optimalen Skill- und Grade-Mix in der Dialyse ist in Österreich in erster Linie der aktuell gültige gesetzliche Rahmen des österreichischen Gesundheits- und Krankenpflegegesetzes konzeptleitend. Da es in diesem Funktionsbereich ausschließlich Pflegepersonal mit Sonderausbildung bzw. künftig mit einer Spezialisierung bedarf, ist das derzeitig geforderte Fachpersonal die Berufsgruppe des gehobenen Dienstes für Gesundheits- und Krankenpflege. Durch die Normierung der neuen Berufsgruppen Pflegefachassistenz und Pflegeassistenz in der Gesundheits- und Krankenpflege werden Kompetenzerweiterungen und Aufgabenverteilungen im klinischen Setting neu angeregt. Ein visionäres Zukunftsszenario, welches bereits im europäischen Raum wie bspw. in Deutschland praktiziert wird, wäre auch für Österreich denkbar und umsetzbar. Dazu werden behandlungsbezogene Tätigkeiten den erforderlichen Berufsgruppen auf einer Dialyse zugeschrieben.

Published: April 2020

Abstract
Background In thoracic surgery, utilization of extracorporeal membrane oxygenation (ECMO) is mainly established for patients undergoing lung transplantation. The aim of our study was to summarize our single-center experience with intraoperative use of veno-venous- or veno-arterial-ECMO in patients undergoing complex lung surgery involving the main carina, or the left atrium or the descending aorta.
Methods A total of 24 patients underwent combined complex lung, carinal, aortal, or left atrial resections. In cases of carinal resection, percutaneous veno-venous, jugular–femoral cannulation was considered suitable. For combined resection of lung and descending aorta, a percutaneous femoral veno-arterial cannulation was used. In cases of extended left atrial resection, a percutaneous jugular–femoral veno-venous-arterial cannulation was favored.
Results Procedures were divided into three groups: carinal resections and reconstruction (n = 8), resections of the descending aorta and left lung (n = 7), resections of lung and left atrium (n = 9). No intraoperative complications occurred. Overall 30-day mortality was 25%. A complete resection was achieved in 18 patients. Median survival was 12 months. One- and 5-year survival were 48.1 and 22.7%, respectively.
Conclusion The present study shows that intraoperative use of ECMO for extended carinal, aortic, or atrial resections is feasible with minimal intraoperative complications allowing surgeons increased operating-field safety. Perioperative mortality is high, but this is rather an attribute of local extended disease and patient comorbidities.

AbstractThe study evaluates the meniscal tissue after primary meniscal suturing using 7-Tesla (T) magnetic resonance imaging with T2* mapping at 6 and 12 months after surgery to investigate the differences between repaired meniscal tissue and healthy meniscal tissue in the medial and lateral compartment. This prospective study included 11 patients (9m/2f) with a mean age of 30.6 years (standard deviation 9.0). Patients with a meniscal tear that was treated arthroscopically with meniscus suturing, using an all-inside technique, were included. All patients and seven healthy volunteers were imaged on a 7-T whole-body system. T2* mapping of the meniscus was applied on sagittal slices. Regions-of-interest were defined manually in the red and white zone of each medial and lateral meniscus to measure T2*-values. In the medial posterior and medial anterior horn similar T2*-values were measured in the red and white zone at 6- and 12-month follow-up. Compared with the control group higher T2*-values were found in the repaired medial meniscus. After 12-months T2*-values decreased to normal values in the anterior horn and remained elevated in the posterior horn. In the red zone of the lateral posterior horn a significant decrease in the T2*-values (from 8.2 milliseconds to 5.9 milliseconds) (p = 0.04), indicates successful repair; a tendency toward a decrease in the white zone between the 6 and 12 months follow-up was observed. In the red zone of the lateral anterior horn the T2*-values decreased significantly during follow-up and in the white zone of the lateral anterior horn T2*-values were comparable. In comparison to the control group higher T2*-values were measured at 6-months; however, the T2*-values showed comparable values in the repaired lateral meniscus after 12 months. The T2* mapping results of the current study indicated a better healing response of the red zone of the lateral posterior horn compared with the medial posterior horn.

Abstract
The finite difference method for discretization space fractional chemotaxis model is introduced in this study. The space fractional chemotaxis system is obtained from the classical advection-diffusion equations of the chemotaxis system by replacing the spatial derivative with a generalized derivative of fractional order. We compare the numerical solution of finite difference method and exact solution for a test example. The results reveal that the finite difference method is very simple and efficient for solving space fractional chemotaxis system.
Nonlinear Dynamics of a Magnetically Supported Flexible Rotor in Auxiliary Bearings
Authors: Inayat-Hussain Jawaid I 
Published: April 2020

Abstract
The results of a numerical simulation on the nonlinear dynamics of a flexible rotor mounted on magnetic and auxiliary bearings are presented in this work. The focus of this work was to investigate the effect of shaft flexibility on the rotor response during load sharing operation between the magnetic and auxiliary bearings. For the range of parameters considered herein, results from the numerical simulation showed that the stiffness ratio, which represented the contact stiffness of the auxiliary bearing, was a more effective parameter, as compared to the Coulomb sliding friction coefficient, for the suppression of sub-synchronous and non-synchronous vibrations in the rotor’s response. Sub-synchronous vibrations of period-2, period-4, period-8 and period-16 were observed in the response of the rotor. Non-synchronous vibration which was also seen in the rotor’s response was determined to be chaos. For the case of the rotor response with variation of the stiffness ratio, the route to chaos was found to be due to a sequence of period-doubling bifurcations, where the synchronous or period-1 response bifurcated into period-2, period-4, period-8 and period-16 responses, culminating into chaotic vibration. Vibrations which are of sub-synchronous and non-synchronous nature are best avoided in the rotor’s response during operation, whereby the load is shared between magnetic and auxiliary bearings, as they produce stress reversals. Such stresses can potentially cause fatigue failure of the rotors and their associated structures.
State estimation for dynamic weighing using Kalman filter
Authors: Pitawala S 
Published: April 2020

Abstract
Dynamic weighing has become an essential requirement in a diverse range of industries. In dynamic weighing, loadcell based weighing mechanisms are employed in determining the weight of the products while they are in motion. This paper proposes a method of weight ascertainment based on state estimation theory. A simplified time domain response of the weighing system is modelled as an output error model and the 1-D Kalman filter is used in two stages to determine the weight of the fruit. The dependency of the weight with the change of speed is taken into account in the calibration stage. The validity of the method is tested using the data provided by Compac sorting equipment, Auckland, New Zealand.

Abstract
Liquid fuel from polystyrene plastic waste with co-reactant of cooking oil waste biodiesel has been obtained. The catalysts used in catalytic cracking are Al-MCM-41/ceramic and Pd/Al-MCM-41/ceramic catalysts. Morphology and elemental composition were observed with SEM EDX, the crystal structure observed with XRD, surface area and pore volume were analyzed by Nitrogen adsorption-desorption each calculated by BET and BJH method, acidity determined by FTIR-Pyridine, and temperature resistance analyzed by DTA. The results of catalytic cracking were investigated using Gas Chromatography-Mass Spectroscopy (GC-MS). Characterization of the catalyst showed that acidity was reduced because the Si/Al ratio was reduced after the impregnation and the surface area of Al-MCM-41/ceramics also decreased. SEM EDX shows that the composition of the carbon element on the surface of the Pd/Al- MCM-41/ceramic catalyst is smaller compared to the Al-MCM-41/ceramic catalyst. The results of the GC-MS characterization of liquid fuels from catalytic cracking using Pd/Al- MCM-41/ceramics catalyst, have a percentage of gasoline fraction (C7-C12) of 74.9% at 120 minutes cracking. The mixture of fuel from the addition of 150 mL liquid fuel resulting from catalytic cracking with Pd/Al-MCM-41/ceramic catalyst has the highest calorific value of 19160.61 (kcal/kg) and the performance of the gasoline Genset engine has the highest thermal efficiency of 28.27%.

The following design also includes heating systems, insulation systems, and material handling. Temperature analysis was focused on temperature distribution on sintering sample. The temperature distribution was also analyzed based on the material layout during the sintering process. All results were based on heat transfer, confirmed by ANSYS software.The dimension of the CF for application of P/M production is (L x W x H): 3 x 500 x 500 x 360 mm3 with the length (feed zone, pre-sinter zone, sinter zone, post-sinter zone dan discharge zone) was 500 mm and length of cooling zone is 1440 mm. The material production rate was 874 material/hour. The heating system uses kanthal AF with diameter of 1,6 mm, length of heating element 3,4 m, total power of 30 kW, voltage of 220 V, and total current 135 A. Insulation system uses composite wall with insulating brick (11 cm thickness) and ceramic fiber blanket (5 mm thickness). The material handling system uses mesh belt conveyor from material SS314 with length of 4190 mm, width of 356 mm, and conveyor speed of 0,277 mm/s. The standard temperature for pre-sinter zone is 225 °C while the design obtained 210.44 °C and sinter zone is 300 °C while the design obtained 293.52 °C. The results showed that the optimum zone temperature in the pre-sintered (225 °C) and sintered zones (300 °C) are 210.44 °C and 293.52 0C, respectively. Validation of heat balance shows that the deviation was minimal and can be ignored, thus the design is considered the most suitable.

Authors: Ulimaz M , Jordan N A 
Published: April 2020

Abstract
Manggar Riverbank is one of the high-density settlements with characteristics of wood as the main material. Most residents were worked as fishermen and farmers to support minapolitan (fishing town) activities. The area was located on the edge and surface of the river, linear housing patterns, parallel, and surface the river. The area has been indicated as slum river settlements. The strategy to urban development based on green infrastructure (ecological infrastructure) must be integrated with Balikpapan Spatial Plan (RTRW). Manggar village was established as a traditional protected settlement. Green infrastructure planning should be integrated with the residential space to improve the quality of city and community life. The concept of sust ainable city development needs to balance economic, socio-cultural and environmental development by increasing green infrastructure. The purpose of this study is to analyze the priorities of green infrastructures based on its pattern. The distribution patterns by Geographic Information Systems approach was used as a methodology. The results of the analysis concluded that there were three patterns identified from the distribution of green infrastructure in the village over the Manggar riverbank settlement. Clustered patterns, random patterns, and dispersed patterns are found in all variables with different amounts. Clustered patterns are found in the distribution of vegetation. This result shows that the priority of the Manggar village community readiness in preparing the green infrastructure of settlements is available on vegetation. The clustered vegetation does not show a relationship with fishing activities, but rather tourism activities. Green infrastructure that is dispersed according to the use of fisheries space is lighting and public buildings with random patterns.

Authors: Harfadli M M 
Published: April 2020

Abstract
Leachate is a concentrated liquid that is harmful to soil and groundwater. This liquid comes from the process of decomposition of waste material by microorganisms in landfills. Leachate has the characteristics of high organic content. To reduce the organic content, one of them is to increase the dissolved oxygen in leachate. The method used with the aeration diffuses. Especially, using fine bubble aeration. Based on this background, a leachate water treatment was carried out using the fine bubble aeration system in order to see the effect on the value of dissolved oxygen or DO produced. The method in this experiment using a closed reactor system by varying nozzle diameter as a control variable. They are 1.5 mm, 2 mm and 3 mm. The air pressure use 3 bar. Aeration time from 0 to 120 minutes. The volume of water as much as 25 Litre. The results showed that there was an effect of nozzle size on DO values. The highest increase in DO occurred in 1.5 mm diameter reaching 7.4 mg/L, while the highest 2 mm and 3 mm DO sizes reached 6.6 mg/L and 6.6 mg/L respectively. Based on the comparison of DO values of each diameter, it can be concluded that the 1.5 mm is more effective in increasing the dissolved oxygen concentration in leachate water treatment using fine bubble aeration. According to bivariate analysis, the nozzle diameter as a control variable has a very strong relationship with the DO value indicated by the correlation value approaching 1 (0.701) with the aeration time change scenario.

Published: April 2020

Abstract
One solution to the problem of energy that can be used as a substitute for fuel oil is biodiesel. Palm oil can be used as biodiesel raw material. The advantage of palm oil is its sustainable availability. However, the water content of palm oil still cannot meet the biodiesel quality requirements based on ASTM D975-08a and ASTM D6751-12 which is less than 0.05%. The purpose of this study is to model and optimize the concentration of zeolite and adsorption times to decrease water content in palm oil. The method in this research is to use activated zeolite adsorption. Data from the results of water loss in palm oil as a pretreatment in the manufacture of biodiesel will be processed using response surface methodology (RSM) with the central composite design (CCD) so that a model and optimum point of zeolite concentration and adsorption time can be found. The model produced using the response surface methodology (RSM) method with a central composite design (CCD) design in the form of quadratic equations. The optimization results produce an optimum value of water loss of 2.74% with an error rate of 4.20%. This optimum value is achieved by zeolites concentration of 13.20% and adsorption time of 126.11 minutes.
