Published: July 2020

AbstractPulmonary artery sling is a rare congenital vascular abnormality, where the left pulmonary artery originates from the right pulmonary artery, passes between trachea, and esophagus and reaching the left hilum. Cough, wheezing, and difficulty in feeding are three major symptoms. Untreated pulmonary sling carries high morbidity and mortality, most of which is due to the airway and other associated anomalies. Herein, we reported a 40-day-old male infant who admitted to the pediatric intensive care unit with progressive respiratory distress and diagnosed with left pulmonary sling with tracheal stenosis. We discussed the diagnosis and management of pulmonary artery sling and present the successful use of laryngeal mask in difficult airway management.
Social and Economic Challenges to Implementing the Ketogenic Diet: A Case Series
Authors: Lynch Sloan , Barry Catherine , Douglass Laurie M. 
Published: July 2020

AbstractThe ketogenic diet (KD) is a powerful therapeutic tool that can reduce seizure activity in patients with refractory epilepsy. However, dietary implementation can be difficult for patients and families due to the time and resource intensive nature of the diet. These challenges are particularly pronounced in economically disadvantaged or socially unstable patient populations. The first case of this series describes the successful implementation of KD in a low-income, homeless patient through the use of innovative KD recipes and access to social programs offered through Boston Medical Center. The second case illustrates the importance of consistent parental support to the success of KD and describes mechanisms used to improve familial support within a nonunified household. Collectively, these cases demonstrate ways by which health care providers can make this powerful dietary treatment accessible to low-resource patients.
Planetary health in practice: sensing air pollution and transforming urban environments
Authors: Gabrys Jennifer 
Published: July 2020

AbstractOften, health is seen to be a matter of attending to individuals and their behaviour, or of studying populations in order to manage disease. However, pollution is a problem of the health of environments, as much as it is a problem of the health of bodies. To understand health and pollution, it is necessary to examine energy-intensive infrastructures and developed environments that produce air pollutants and impair ecosystems. In other words, air pollution requires approaches to health that are planetary in scope and that account for the socio-environmental processes and relations that make health possible. Planetary health is often approached as a broad analysis of earth systems. However, diverse and situated environmental practices also contribute to the formation of planetary health. This article asks how citizen-sensing practices tune into the problem of air pollution in Southeast London, and in so doing differently configure pollution and planetary health. While many sensing technologies promise to make citizens into more capable political actors through the collection of data, this research investigates how communities use sensors in distinct ways to support, activate or extend community-led projects in urban environments. Rather than citizen-sensing practices contributing to improved air quality through the abstract circulation of data, we found that environmental monitoring became enmeshed in ongoing and broader struggles to improve the health of urban environments. These practices not only challenge the official scripts of sensing devices, they also remake the usual ways of demarcating health in relation to air pollution by shifting away from individual behaviour and toward collective environmental actions. This article then asks how community proposals for urban design and action conjoin with citizen-sensing practices to generate strategies for reworking and reconstituting health toward more planetary compositions.
Legal argumentation in Mesopotamia since Ur III
Authors: Schumann Andrew 
Published: July 2020

Abstract
In this paper, I show that we can find some foundations of logic and legal argumentation in the tablets of
Mesopotamia at least since the dynasty of Ur III. In these texts, we see the oldest correct application of logical inference rules
(e.g. modus ponens). As concerns the legal argumentation established in Mesopotamia, we can reconstruct on the
basis of the tablets the following rules of dispute resolutions during trials: (1) There are two parties of disputants: (i) a
protagonist who formulates a standpoint and (ii) an antagonist who disagrees with the protagonist’s standpoint and formulates an
alternative statement. (2) There is a rational judge represented by high-ranking citizens who should follow only logical
conclusions from facts and law articles as premises.
Fast Data-Driven Simulation of Cherenkov Detectors Using Generative Adversarial Networks

Published: July 2020

Abstract
The increasing luminosities of future Large Hadron Collider runs and next generation of collider experiments will require an unprecedented amount of simulated events to be produced. Such large scale productions are extremely demanding in terms of computing resources. Thus new approaches to event generation and simulation of detector responses are needed. In LHCb, the accurate simulation of Cherenkov detectors takes a sizeable fraction of CPU time. An alternative approach is described here, when one generates high-level reconstructed observables using a generative neural network to bypass low level details. This network is trained to reproduce the particle species likelihood function values based on the track kinematic parameters and detector occupancy. The fast simulation is trained using real data samples collected by LHCb during run 2. We demonstrate that this approach provides high-fidelity results.
Assessing the temperature of plasma produced in carbon dioxide (CO2) Laser-Induced Breakdown Spectroscopy (LIBS) from soil sample prepared by two different methods of metal mesh and silicone grease

Published: July 2020

Abstract
Temperature of plasma generated by CO2 laser from soil sample prepared by the two different methods, namely metal mesh, and silicone grease methods, was examined. The plasma was produced by focusing the laser beam on the sample at 1 atmospheric pressure. The plasma characteristics namely temperature was estimated by the Boltzmann plot method. The detection was made in region of 300 nm-400 nm. In the case sample prepared using the metal mesh method, the estimated temperature was about 11605 K for the metal mesh no. 50 and 12440 K for mesh no. 40, respectively when helium was used as surrounding gas. When air was used as surrounding gas, plasma temperature was about 10315 K and 10990 K, respectively. In case the soil sample prepared by soil mixed with silicon grease (SMS) smeared on a surface of metal sub target, plasma temperature was about 8913 K and 9218 K for air and helium as a surrounding gas, respectively. It can be concluded that plasma temperature is not significantly different although the sample was prepared with different methods.
Complexity and neutron stars with crust and hyperon core
Authors: Adhitya H , Sulaksono A 
Published: July 2020

Abstract
Continuing the work of K. Ch. Chatzisavvas and others [1], a measure of complexity proposed by R. López-Ruiz, H.L Mancini, and X. Calbet [2] is used to study a model of neutron star (NS) with crust and hyperon core. We employed the relativistic-mean-field approximation theory to build the Lagrangian density model of the neutron star’s core and from it, obtained the equation of state (EoS), ∈(ρ). This ∈(ρ) was then put into the complexity equation and the complexity-values were obtained using numerical methods. Plotted against the corresponding mass values, the results show that neutron star’s complexity-mass curves behave very similarly to an isolated-system phase complexity diagram, which was not apparent in the previous work by Chatzisavvas et al.. The reason for this is that the crust EoS put an upper limit to the complexity value and it follows that the crust itself is an ordered system of low complexity. We also show that NS have the properties of a perfect crystal although they are modeled as liquid.

Published: July 2020

AbstractPolyaniline can be used as an electrode because it is a conductive polymer whose conductivity can be adjusted through a doping-dedoping process. This study aimed to synthesise polyaniline film for use as a substrate for Fe-Ni alloy electrodeposition. A polyaniline layer was synthesised using the galvanostatic technique with a current of 1 mA in three-electrode cells. The results of Fourier transform infrared analysis showed that the deposit formed was the emeraldine salt phase of polyaniline. The formation of a polyaniline deposit was confirmed by differential scanning calorimeter and X-ray diffractometer. The scanning electron microscope micrograph showed that the layer growing on the substrate was porous polyaniline, which had uniform morphological characteristics. This polyaniline was used as a substrate in the electrodeposition of FeNi alloys and produced a uniform silvery layer even though it grew above the porous substrate.

Published: July 2020

Abstract
Moisture content, ash content and heating value have been measured on briquettes which were made from a mixture of halaban charcoal and coal bottom ash with variations in pressures and form factor. Factors that influence the characteristics of briquettes were powder fineness and pressure. And so both materials were made in the form of powder on a 250 mesh sieve and pressure variations (150, 200, 250, 300, and 350) kg / cm2. The composition of the mixture of halaban charcoal and coal bottom ash was with a ratio of 90%: 10%, while 5% of starch adhesive was added. Briquettes were made in the form of solid cylinders and hollow cylinders. From the measurements, the moisture content, ash content and heating value of solid cylinder briquettes were yielded 3.831-5.892%, 7.178-10.507% and 5,607.467-5,732.033 cal/g, respectively. While for hollow cylinder briquettes were 4.564-5.621%, 8.688-11.191% and 5,620.833-5,685.100 cal/g. All briquette samples meet Indonesian national standards requirements for moisture content and heating value, but not all briquette samples meet the requirements for ash content. Higher pressure gave lower water and ash content, but higher heating value. Based on the results, it is recommended that the pressure given in making the briquette was 200 kg/cm2. This is based on consideration of the highest heating value obtained when the pressure was 200 kg / cm2.

Authors: Andayany H , Loupatty G , Kelibulin J R 
Published: July 2020

Abstract
An investigation of alteration minerals has been carried out using the XRD (X-ray diffraction) method in several geothermal areas on Ambon Island. There are 4 (four) regions that are mapped as potential areas for the development of geothermal energy in Ambon islands, including Hatuasa geothermal energy, TalangHaha, Suli, and Waiyari. The results of the investigation interpret that rock samples in the Hatuasa geothermal region are dominated by quartz wacke with rock fragments in this area in the form of quartz minerals, pyroxene, opaque minerals, and feldspar while the matrix is clay minerals. The interpretation of rock samples in the TalangHaha, Suli and Waiyari regions is almost the same which is dominated by feldspathic greywacke with fragments in the form of quartz minerals, opaque minerals, lytic, and feldspar, while the matrix is clay minerals. Those minerals are alteration mineralsfrom the original minerals. The appearance of mineral changes in these areas shows that the reservoir temperature in these areas is very high. In addition to changes in the appearance of minerals, the potential of geothermal energy in some areas of Ambon Island can also be interpreted from the results of measurements of flowrate. Flow discharge in the Hatuasa, TalangHaha, Suli and Waiyari regions ranged from 0.19 m3/second; 0.16 m3/second; 0.13 m3/second and 0.20 m3/second give the results of heat loss calculations which are 86.4 kW; 71.8 kW; 72.4 kW and 114.19 kW. Thus the Hatuasa, TalangHaha, Suli and Waiyari geothermal fields can be used as a basis for recommendations on the utilization of geothermal potential for local governments (indirect use), namely as information to meet the shortage of electricity in Ambon Island.
Radioactivity yields of Galium-67 applicable for scintigraphy of various visease in nuclear medicine
Authors: Kambali I 
Published: July 2020

Abstract
In nuclear medicine, gallium-67 (67Ga) is potentially applied for imaging a certain type of tissue. In this investigation, 67Ga is theoretically studied in terms of its potential radioactivity yield at the end of various energetic proton bombardments. Nuclear cross-sections derived from the TALYS-2017 codes were used to perform yield calculations of 67Zn(p,n)67Ga and 68Zn(p,2n)67Ga nuclear reactions. Two different targets –enriched 67Zn and 68Zn targets – were simulated in the calculations. The calculated yields suggested that a maximum of 27.37 MBq/μAh when enriched 67Zn target is irradiated with 15-MeV protons, whereas 46.99 MBq/μAh could be generated following a 30-MeV proton bombardment of enriched 68Zn target. Various radioactive gallium impurities such as 63,64,65,66,68,70Ga and stable isotope 69Ga were also expected to be generated mostly via (p,n) and (p,2n) reactions when natZn target was used in the 67Ga production. In contrast, radioactive 66Ga and 68Ga impurities were mainly produced following bombardment of enriched 67Zn and 68Zn targets.

Published: July 2020

Abstract
This study aims to investigate the structural and morphology of ZnO nanorods in the variation of precursor ratio on stainless steel substrate and its piezoelectric nanogenerator performance. ZnO nanorods are grown on a stainless steel substrate that has been coated with ZnO as a seed layer by a modified hydrothermal method in the variation of molar ration between Zinc nitrate tetrahydrate (ZNT) and hexamethylenetetramine (HMT). X-ray diffraction (XRD) and scanning electron microscope (SEM) were performed for structural properties and morphology characterization. The performance of the piezoelectric nanogenerator was carried out by measuring voltage and current in applying an external force to the device. The ZnO-nanorods has a hexagonal wurtzite structure. The average length of ZnO-nanorods increased and the average diameter decreased by increasing ZNT/HMT ratio. The current and voltage of the piezoelectric nanogenerator increased with increasing by increasing the zinc nitrate ratio. These results indicate that the ZNT and HMT precursor ratio is playing an important role in the growth of ZnO nanorods that implicates the performance of the piezoelectric nanogenerator with stainless steel substrate.

Abstract
The potential of the composite membranes chitosan-silver nanoparticles (Ch-AgNP) to remove silver (Ag) from X-ray film processing wastes was studied using a filtration method. The study includes the pure water flux (PWF), product flux (PF), and rejection coefficient (R). Several of composite membranes such as Ch-AgNP10, Ch-AgNP100, Ch-AgNP250, Ch-AgNP500, and a pure chitosan membrane (Ch) were used in this study. The filtration was carried out using a dead-end filtration method with a pressure of 260-270 kPa. The concentration of silver waste was determined using Atomic Absorption Spectroscopy (AAS). The results showed that the composite membranes have a better ability to filter silver from X-ray film processing wastes than the pure chitosan membrane. The highest rejection coefficient (R) gave by Ch-AgNP100 of around 95.55% with the pure water flux and product flux of 2051.03 and 1192.28 L/m2·h, respectively. The rejection coefficient of the composite membranes increased with increasing the mass of silver nanoparticles, while the PWF and PF were decreased. These results indicated that chitosan composite membranes are a potential method for recovering silver from X-ray film processing wastes. It’s a safe and environmentally friendly method.
