Published: April 2020

Background:
Nano perovskite-type structures as denoted by ABO3 (A= RE) have been
popular targets of fundamental investigations since they exhibit a wide variety of physical properties
depending upon the chemical composition, defects and small changes in atomic arrangements.

Methods:
GdAlO3: Co2+ (1, 3 &9 mol %) was synthesized using the solution combustion method by
using stoichiometric quantities of gadolinium nitrate [Gd (NO3)3], aluminium nitrate (Al (NO3)2, and
cobalt nitrate Co(NO3)2.

Results:
The morphology, structure and particle size of the prepared GdAlO3: Co2+ sample were
characterized by transmission electron microscope (TEM) image. The Fourier transform infrared
(FT-IR) spectral analysis confirmed that the as-prepared powder was in pure state. Electrochemical
impedance measurements (EIS) of different GdAlO3: Co2+ samples were measured vs. Ag/AgCl in
the frequency range of 1 Hz to 1 MHz with AC amplitude of 5 mV at steady-state which clearly indicated
that Co2+ dopant is a successful doping material for the fabrication of supercapacitors.

CONCLUSION:
Electrochemical impedance measurements (EIS) of different GdAlO3: Co2+ samples
were measured vs. Ag/AgCl in the frequency range of 1 Hz to 1 MHz with AC amplitude of 5 mV at
steady-state which clearly indicated that Co2+ dopant is a successful doping material for the fabrication
of supercapacitors. From a future perspective, we believe that GdAlO3: Co2+ composite material
could be a promising electrode material for the fabrication of various sensors, supercapacitors and
solar cells.

Published: April 2020

Background
Coronavirus disease (COVID-19) has been an unprecedented challenge to the global health care system. Tools that can improve the focus of surveillance efforts and clinical decision support are of paramount importance.

Objective
The aim of this study was to illustrate how new medical informatics technologies may enable effective control of the pandemic through the development and successful 72-hour deployment of the Honghu Hybrid System (HHS) for COVID-19 in the city of Honghu in Hubei, China.

Methods
The HHS was designed for the collection, integration, standardization, and analysis of COVID-19-related data from multiple sources, which includes a case reporting system, diagnostic labs, electronic medical records, and social media on mobile devices.

Results
HHS supports four main features: syndromic surveillance on mobile devices, policy-making decision support, clinical decision support and prioritization of resources, and follow-up of discharged patients. The syndromic surveillance component in HHS covered over 95% of the population of over 900,000 people and provided near real time evidence for the control of epidemic emergencies. The clinical decision support component in HHS was also provided to improve patient care and prioritize the limited medical resources. However, the statistical methods still require further evaluations to confirm clinical effectiveness and appropriateness of disposition assigned in this study, which warrants further investigation.

Conclusions
The facilitating factors and challenges are discussed to provide useful insights to other cities to build suitable solutions based on cloud technologies. The HHS for COVID-19 was shown to be feasible and effective in this real-world field study, and has the potential to be migrated.
Fractal Hilbert sensor to detect partial discharge on transformer
Authors: Sinaga Herman Halomoan 
Published: April 2020

The design of fractal Hilbert sensor is presented in this paper. The sensor is intended to detect partial discharge (PD) in transformer insulation. The fractal Hilbert sensor designed using 4 order fractal and etching on single layer PCB board. The Hilbert fractal type is chosen as this type of sensor can be built on smaller area compare to other types. The sensor overall dimension is limited to 5x5 cm as it is proposed to be use to detect the PD presence in transformer. The sensor sensitivity is tested using a closed type TEM cell. After the sensitivity of the sensor is tested the sensor then applied to detect the PD signals emitted by void PD defect model. The results show the sensor has sensitivity as high as 10 dB. The sensor also has capability to detect the PD signals generated by the PD defect source. The waveforms captured by the sensor show the sensors can capture high frequency pulse generated by the PD source. Keywords: Partial Discharge (PD), Fractal Hilbert Sensor UHF, Sensor Sensitivity

Verliebtheitsgefühle und damit assoziierte Phänomene gegenüber PatientInnen in der Psychotherapie
Authors: Rhyn Esther , von Wyl Agnes 
Published: April 2020

Verliebtheitsgefühle sind etwas Wunderbares und lassen die Gefühlswelt zu einer Achterbahn werden. Wenn derartige Empfindungen jedoch im psychotherapeutischen Setting gegenüber PatientInnen auftreten, können sie brisant sein. Dies stellte schon Freud fest. Diesbezüglich prägte er das Konzept der Gegenübertragung, das in den letzten 100 Jahren weiterentwickelt wurde. Empirische Untersuchungen zum Thema Verliebtheitsgefühle vonseiten Therapierender liegen viele Jahre zurück. Deshalb wurde in dieser Arbeit die Prävalenz von Verliebtheitsgefühlen und damit assoziierten Phänomenen gegenüber PatientInnen sowie entsprechende Einflüsse und Erklärungsmuster schweizweit bei PsychotherapeutInnen untersucht. Die Antworten der 409 Teilnehmenden wurden anhand quantitativer und qualitativer Methoden ausgewertet. Die Ergebnisse zeigen, dass Verliebtheitsgefühle und viele der damit assoziierten Phänomene relativ häufig gegenüber PatientInnen vorkommen und dass dabei der Genderaspekt eine bedeutende Rolle spielt. Bezüglich Erklärungsmuster ist insbesondere hervorgegangen, was die Befragten unter Verliebtheitsgefühlen im therapeutischen Setting verstehen, wie sich ihnen Verliebtheitsgefühle gegenüber der Klientel gezeigt haben und weshalb diese Empfindungen entstehen können oder verhindert werden. Die Ergebnisse bieten eine breite Diskussionsbasis und regen zur Reflexion über ein heikles und oft tabuisiertes Thema an.
ENERGY BALANCE DURING FREIGHT ELECTRIC LOCOMOTIVE OPERATION
Authors: Zarif'yan Aleksandr 
Published: April 2020

The purpose of this work consists in obtaining power indices of a freight electric locomotive at the specified schedule of motion, but at different laws of speed changes and on different track profiles.
CAD methods are used, at that, the further comparison of the results obtained with the records of the locomotive crew recorder has shown an actually complete coincidence.
As expected, a minimum work performed for a train hauling is achieved in an ideal case – at the motion without stops at a constant speed on a straight horizontal track. When moving along an actual profiled track a work performed for hauling changes by a difference of potential energy of gravity in the initial and end points.
Often accelerations and slowdowns result in the work increase for hauling, for that there are obtained quantity values. In order to avoid excess power waste it is necessary to move possibly without sharp accelerations and hard braking. To support motion uniformity it is expedient to use a speed controller.
There are obtained the values of a specific work for train hauling in different cases which define limits for a purpose index on the
Oxidative Stress Levels in Orthodontic Patients and Efficacy of Antioxidant Supplements in Combating Its Effects- A Randomized Clinical Study
Authors: Yamyar Sheetal , Daokar Suchita 
Published: April 2020

Introduction: Orthodontic appliances are considered to be biocompatible although adverse effects attributed to release of nickel ion which are free radicals in oral cavity. These free radical produce damages both in cellular and extracellular components phospholipid membrane, proteins, mitochondrial and nuclear DNA leading to Oxidative stress which is normally counter balanced by the action antioxidant mechanisms. However in higher concentrations of free radicals resulting in cellular death and apoptosis Orthodontic appliances such as brackets, wire, resins has considered as potential allergen leading to release of free radicals. The study was conducted to determine and compare the role of oxidative stress and role of antioxidants in saliva of patients undergoing fixed orthodontic appliances therapy at different time intervals.
Materials & Method: A double-blinded, parallel, randomized clinical study was designed consisting of 40 healthy participants, aged 15-30yrs. The samples were divided into two groups Group A without antioxidants supplements and Group B with antioxidants supplements. Salivary MDA levels and gingival health index was recorded at different time intervals from each group. Salivary Lipid peroxidation (Malondialdehyde) level was estimated using Thiobarbituric acid (TBA) method and gingival status was investigated using Silness & Loe gingival index. Intragroup and intergroup comparison was statistically analyzed using student’s paired T test.
Result: Increased salivary MDA levels and mild to moderate amount of gingivitis is seen in both groups. This is more pronounced after 24 hours of appliance placement. Improvement in salivary MDA levels and gingival health status is observed during the course of treatment, In Group B the salivary MDA levels and gingival health index score reached below their pretreatment values. However even after a span of 3 months the levels remained higher to their base values in Group A.
Conclusion: Improvement in salivary MDA levels and gingival health status is observed following antioxidant therapy during course of treatment, indicating combating nature of antioxidant supplements in orthodontic patients.

Published: April 2020

Introduction: Adolescence is the time when a person attains awareness including the self-awareness about his/her health. Hence if proper knowledge is instilled during this time, it will be effective and good oral health behavior can last lifetime. The aim of this study was to assess knowledge and attitude towards orthodontic treatment among the students of public and private schools and compare between them.
Materials & Method: A descriptive cross-sectional questionnaire-based study was performed among 700 students (350 from private and 350 from government schools around Kathmandu valley) of grade 8-10. Questionnaire consisted of 14 questions about knowledge and 10 questions about attitude relating to orthodontic treatment. Each response as “yes” was given score ‘1’ and responses “no” and “don’t know” were given score ‘0’. Total score was calculated, followed by mean and compared between that of private and government schools and between genders.
Result: No significant difference was found in the knowledge between the students of private and government schools. The difference in attitude score was found to be statistically significant (p=0.00). 54.29% of participants had never heard of an orthodontists, 48.57% never thought that crooked teeth have ill effects, and around 50% of participants were not aware that orthodontic treatment would improve the facial appearance. 47% of participants would not undergo treatment if it took 1-2 years, 53% would not agree for extractions and 42% were not willing to wear retainers.
Conclusion: The knowledge and attitude level on orthodontics can be improved by incorporating the basic aspects of oral health in the syllabus of school education.
