Inflationary Cosmology with Quantum Gravitational Effects and Swampland Conjectures*
Authors: Wu Qiang , Zhu Tao 
Published: September 2019

Abstract
Recently proposed two swampland criteria that arising from string theory landscape leads to the important challenge of the realization of single-field inflationary models. Especially one of swampland criteria which implies a large tensor-to-scalar ratio is strongly in tension with recent observational results. In this paper, we explore the possibility the swampland conjectures could be compatible with single-field inflationary scenarios if the effects due to the quantum theory of gravity are considered. We show that the quantum gravitational effects due to the nonlinear dispersion relation provides significant modifications on the amplitude of both the scalar and tensor perturbation spectra. Such modifications could be either raise or reduce the perturbation spectra depending on the values of the parameters in the nonlinear terms of the dispersion relations. Therefore, these effects can reduce the tensor-to-scalar ratio to a smaller value, which helps to relax the tension between the swampland conjecture and observational data.

Published: September 2019

Abstract
One major cause of Alzheimer’s disease (AD) is evidently due to the aggregation and deposition of amyloid β peptides (Aβ) in the brain tissue of the patient. Preventing misfolding and self-aggregation of Aβ protein can reduce the formation of highly toxic polymer, which is important for the treatment of AD. Among them, the α-helix consisting of 42 residues (Aβ42) is the main component of senile plaques in AD. In this paper, 500 ns accelerated molecular dynamics are performed at different temperatures (300 K, 350 K, 400 K, 450 K) to study of the effect of temperature-induced conformation changes of Aβ42 protein during the unfolding process respectively.

Published: September 2019

Abstract
One parameter for identifying a fish is its body length. To identify the length of fish, it is still done manually using a meter. Manual measurement results in difficulties that are considered inappropriate, less effective and require a long time, especially in large quantities. For this reason, a fish length measuring system is implemented using a web service application that can facilitate measurement to be more effective and efficient. The stage starts from the fish shooting process using an Android camera. Furthermore, in the web application, the image is pre-processing, which is to change the color image into a grayscale image and do the color equation in the background. The grayscale image is segmented object in the form of separation of objects that are not needed in an image of the fish and remove the non-important part of the object to be addressed. Then proceed with the feature extraction process to get the estimated length of the fish. The simulation results show that the web service application system is able to produce an accuracy rate of estimated fish length from 90% to 98%.

Abstract
The use of renewable energy from solar panel systems is increasingly being applied, but until now the utilization has not been maximized. The movement of the sun caused by the rotation of the earth should be taken into account to maximize electrical energy in the solar panel (PV). In this study, a concept was proposed to control the movement of the two-axis sun tracker with smartphones using bluetooth communication. Controlled by rotating two DC motors, two axes are joined together into linear actuators that can extend and shorten, so that the solar panel can move towards the sun. This system uses a light sensor (Light Dependent Resistor) and a gyroscope sensor as input and two DC motors that are placed on each axis as output. The motor driver used is the Monster Moto Shield. Sun tracker that is used based on tetrahedron geometry and uses three light sensors. The light sensor functions to determine the position of the sun while the gyroscope sensor is used to determine the tilt angle of the solar panel. The gyroscope module used is MPU-6050. This system also uses the GY-273 compass sensor which functions to determine the direction of the wind direction. Components of input and output are connected to the ATmega328P microcontroller and wireless communication using bluetooth. The Bluetooth module used is the HC-05 module. The solar panel movement and the power obtained are then monitored and recorded for analysis

Stabilization decreased rice bran flour moisture and those resulted in lower degradation of lipid content during storage periods. Roasting on a pan and heating in microwave oven gave the lowest moisture. Moisture increased on 50 days storage and decreased on 100 days and those tent to affect FFA and peroxide in line with moisture.
Creating Synergy between Village Midwives and Traditional Midwives: To Reduce the Mortality Rate of Mothers and Babies: In the Central Kluet Sub-District Health Centre in South Aceh
Authors: Masyudi  , Usman Said 
Published: September 2019

Abstract
Traditional midwives have been helping assist with birthing from ages past. Traditional midwives are still trusted by villagers to assist with birthing even though official village midwives have now been appointed to every village. The reason that some mothers choose traditional midwives is that they provide assistance with birthing that is more in accordance with the traditional social customs of the people and they are already well known because they come from the village area. The purpose of this study was to get information about the reasons why the traditional midwives are stll providing birthing services and to see if there are opportunities for transfer of knowledge from the village midwives who works for the health service to the traditional midwives so that they can all work together. This study was done with the Central Kluet Sub-District Health Centre or Puskesmas in South Aceh District using a combination of qualitative and quantitative methods. The results of this study showed the women who gave birth in 2016 still used the services of a traditional midwife because the belief in them had been handed down and because the administration or rather lack of it was easy. The techniques for handling the data used reduction and triangulation of the data from the start so that as the data was gathered it was processed continuously to get early results which could be verified with the later data.
