Authors: Pandey Vaibhav , Gopal Saroj C. 
Published: July 2020

AbstractIntroduction Congenital diaphragmatic hernia (CDH) is one of the most common congenital anomalies encountered by pediatric surgeons. With the advances in the pediatric minimal access surgery, its role in the repair of CDH has also increased. We have been using thoracoscopy for the repair for CDH since 2015. We herein report our experience of CDH repair in newborns.Materials and Methods A retrospective review was conducted from July 2015 to December 2019 in the Department of Pediatric surgery after ethical approval from the institutional review board and included all the children with CDH who underwent thoracoscopic repair. The case records were used to assess the demographic details, type of defect, and early and late postoperative complications of thoracoscopy in CDH.Results Thoracoscopic repair was attempted in 29 patients of CDH. Eight (27.5%) patients converted to open procedure and were excluded from the study. Primary closure of the diaphragmatic defect was performed in 90.4% (19) patients. Also, 9.5% (2) children required mesh repair. There was no intraoperative death. Postoperative ventilation was required in 57.1% (12) children. The mean time on the ventilator was 3.03 ± 0.9 days. The mean age of children requiring postoperative ventilation was less compared with children who were extubated in the postoperative period (p = 0.032). The median follow-up in our study was 12 months and 28.5% of patients developed recurrence of the diaphragmatic hernia. All the children underwent laparotomy and repair of the diaphragmatic defect.Conclusion Thoracoscopic repair is a safe and effective option for the repair of CDH in children performed by surgeons with significant procedure experience.

Abstract
Livestock are a crucial source of food, employment, and income for much of East Africa’s rural population. The sector contributes substantially to export revenues, national GDPs, and thus the region’s broader socioeconomic development. Livestock production and related value chains, can be the foundation of resilience and sustainable development for pastoral, agro-pastoral, and mixed crop livestock systems in East Africa.  Yet, livestock face a wide range of challenges, particularly in terms of ensuring sustainable access to and use of water and feeds for livestock. Inadequate availability and supply of quality feed and water critically limit the efficiency of livestock in terms of production, reproduction, animal health and welfare, human health, and the economic benefits derived from livestock-based livelihoods in the region. Countries in East Africa identified lack of animal feed policy, strategy, and institutional framework to support the animal feed sector as a major constraint hindering subsector growth, livestock productivity, resilience, and trade. In order to address this, the first Animal Feed Action Plan was developed for East Africa through a consultative and participatory process. The Action Plan captures experiences and lessons learned by a wide spectrum of stakeholders. It provides a means to collectively address some of the constraints in accessing and using animal feed and provides a guided approach to establish partnership by countries, communities, the private sector, and stakeholders to enhance sustainable production of quality livestock and products. The Action Plan is believed to set a good example for other regions to develop their feed action plan.

Published: July 2020

Abstract
Certifying the data recorded by the Compact Muon Solenoid (CMS) experiment at CERN is a crucial and demanding task as the data is used for publication of physics results. Anomalies caused by detector malfunctioning or sub-optimal data processing are difficult to enumerate a priori and occur rarely, making it difficult to use classical supervised classification. We base out prototype towards the automation of such procedure on a semi-supervised approach using deep autoencoders. We demonstrate the ability of the model to detect anomalies with high accuracy, when compared against the outcome of the fully supervised methods. We show that the model has great interpretability of the results, ascribing the origin of the problems in the data to a specific sub-detector or physics object. Finally, we address the issue of feature dependency on the LHC beam intensity.
Constructing mass-decorrelated hadronic decay taggers in ATLAS
Authors: Søgaard Andreas 
Published: July 2020

Abstract
A large number of physics processes as seen by the ATLAS experiment manifest as collimated, hadronic sprays of particles known as ‘jets.’ Jets originating from the hadronic decay of massive particles are commonly used in searches for new physics. ATLAS has employed multivariate discriminants for the challenging task of identifying the origin of a given jet. However, such classifiers exhibit strong non-linear correlations with the invariant mass of the jet, complicating analyses which make use of the mass spectrum. A comprehensive study of different mass-decorrelation techniques is performed with ATLAS simulated datasets, comparing designed decorrelated taggers (DDT), fixed-efficiency k-NN regression, convolved substructure (CSS), adversarial neural networks (ANNs), and adaptive boosting for uniform efficiency (uBoost). Performance is evaluated using suitable metrics for classification and mass-decorrelation.

Abstract
This work aimed to study the effect of magnetic fields on the current-voltage (I-V) characteristics of a chitosan membrane. The study consists of the plateau length, limiting current density (LCD), and the ratio of resistance of region III (RIII) and region I (RI) (RIII/RI). The chitosan membranes were prepared by a casting method using chitosan as a matrix and acetic acid as a solvent. The chitosan membranes polymerized under a strong magnetic field of 1.5 mT applied along the membrane surface with various times i.e. 2, 4, 8, and 12 h. The I-V measurements were conducted using a cell model with two working electrodes made of platinum and two reference electrodes connected to a voltmeter. The electrolyte solutions used were HCl and CaCl2 with a concentration of 0.025 M. All experiments were carried out at a room temperature of 28.6 °C. The results showed that the plateau length, LCD and RIII/RI of the chitosan membrane is influenced by the magnetic field given during the membrane formation reaction. The magnitude of the impact depends on the length of exposure. These results can be used in tailoring the chitosan membrane according to the application needed.

Based on an analysis of the distribution of this type of prisoner, furthermore we can be interpretation the conditions of under the earth’s surface. The purpose of this investigation is to obtain information below the surface of the earth and coal targets contained in there using the Geoscanning method with Wenner configuration. Based on the results of 3 trajectory inversion of location of 1 resistivity tomography data, the best coal prospect area on line1, line 2, location of 1 (Pit 10) with alluvium and hard material types. Only constraints on line 1, the coal prospects are covered by analysis of weak zones to the east, in the form of swamp soft soil with ground water classification - clay which is characterized by light blue - dark blue with resistivity values 10 - 34.7 ohms/metres to a depth of 30 metres. Whereas on line 2 which is adjacent to vico 1 and silk wells, the condition of the coal land was safe for exploration activities to a depth of 40 metres, without disturbing the oil well area, and far from the silk location, and the condition of the soil material is solid and no weak zone analysis is found. In the Pit 5 area on line 4, the prospect of coal mining is covered by a landslide-prone zone, where the mine location area (pit 5) is dominated by soft soil classification of sandstone material (resistivity 8.6 -49.2 ohms/metres), blue - gray - light green along the long stretch of North - South direction along 240 metres with a depth reaching 24 metres. This area has the prospect of coal having a moderate resistivity (including small for the quality of coal), namely the range 76 - 182 ohms/metres, marked by red - orange - yellow, with a target depth of up to 39.4 metres.

Authors: Dwipayana C A W , Moersidik S S , Pratama M A 
Published: July 2020

Abstract
In the petroleum industry, Naturally Occurring Radioactive Materials (NORM) are often enhanced as a result of industrial operation. Radiation protection must be applied in every step of NORM management including disposal. Top rank choice for NORM disposal is landfill. Landfill must provide sufficient protection to both human health and the environment, not only for future but also for operational phase. Landfill workers, including receiving worker, driver and placement worker, are evaluated to estimate potential exposures resulting from landfill operation. Estimation is done for radioisotopes which are of concern in the oil and gas industry, Ra-226, Ra-228, Th-232 and Pb-210. The TSD-DOSE computer code, developed by Argonne National Laboratory, is use to estimate radiological doses to workers from operations at a treatment, storage, and disposal (TSD) facility. The characteristics of the time needed by workers were obtained from observations and discussions with workers at PPLI Cileungsi Hazardous Landfill. Disposal of NORM Waste in bulk form give higher dose than containerized waste. For receiving worker, Ra-226 gives higher dose and for placement worker higher dose arise from Th-232. The size of the vehicle used to transport NORM waste affects the radiation dose received by landfill workers.
Gravitational wave echoes from quark stars
Authors: Kartini D , Sulaksono A 
Published: July 2020

Abstract
It has recently been reported that gravitational wave echoes at a frequency of about 72 Hz have been detected with the significance of 4.2σ from two neutron star merger event GW170817. Alternatively, the echoes of a gravitational wave can be obtained from ultra-compact stars, i.e., stars with compactness between 1/3 and 4/9. The mass-radius relation of ultra-compact stars is crossing the photon sphere line, where the line obeys the relation compactness equal to 1/3. Furthermore, it has recently been reported that strange stars within a simplest MIT-Bag model with an ultra-stiff equation of state (EoS) where the speed of sound equal to speed of light in vacuum can produce gravitational wave echoes with frequencies on the order of tens of kilohertz. For more realistic models of strange star equation of state, the speed of sound in the matter is physically less than one, and it should be density-dependent. In this report, we will check whether the more realistic EoS of quark stars can emit gravitational wave echoes or not. Here we employ two models of EoSs such as MIT-Bag models with speed of sound =1/√3 and CIDDM models with the density-dependent speed of sound.

These factors are important for school improvement, especially for schools in disaster-risk areas, communities are increasingly asked to improve students’ awareness to environment.
Measuring protein surface density on glass substrate using fluorescence fluctuation spectroscopy
Authors: Wahyuni D , Balland M , Destaing O , Wang I , Delon A 
Published: July 2020

Abstract
Surface functionalization implies to know the surface density of proteins, which, for cellular biology, impacts on cells behavior (motility, spreading, and fate). Contradictory, the quantification of this parameter is lacking. We studied the surface density of deposited proteins on glass using the Image Correlation Spectroscopy (ICS) technique as part of the Fluorescence Fluctuation Microscopy (FFM) methods. As the confocal microscope scans the surface, the proteins deposited on it contribute to the image through the confocal point spread function (PSF). The width of the image autocorrelation is equal to the width of the PSF; its amplitude provides the average number of proteins within the PSF, proportional to the surface density. Nevertheless, the assessment of the surface density can be underestimated if the surface coverage is not uniform or overestimated if a background contributes to the fluorescence signal. Hence, we combine the ICS and photobleaching (pICS) to detect these artifacts and estimate the actual surface density. The pICS method makes it possible to have a better control of the estimation of the surface density. We noticed that the surface density of proteins increased with their initial concentration in solutions. Overall, FFM is a quantitative technique to infer the surface density of protein.

Abstract
Research has been conducted relating to the concept of forces in physics learning. The purpose of this study is to identify student’s misconception and difficulties in determining the weight and normal from tail of vector, the weight and the normal direction of vector and Newton third law. The study was conducted in two groups of students. The first group was microteaching class and the second group was students who had studied mechanics. The research method is carried out with two approaches namely qualitative and quantitative. The quantitative method is done by using a test instrument given to participants through the pre-test and post-test stages. While the qualitative method of conducting interviews with participants after the post-test session. The results of the study showed that 55% of students were unable to determine the exact gravity capture point, and 93% of students were unable to describe the exact position of the normal force, and 95% of students answered incorrectly about the concept of action forces similar to the reaction forces. From the interviews, it was revealed that students were still confused by the representation of the vector of force representations and not sure about the drawing vector they made. Physics will be well understood if style concept learning is given on the basis of the philosophy of science correctly. Research recommendations are very important that students understand the concept of forces correctly which is based on the application of appropriate vector concepts.
