Published: November 2020

Abstract
Breath analysis is an alternative approach for disease diagnosis and for monitoring therapy. The lack of standardized procedures for collecting and analysing breath samples currently limits its use in clinical practice. In order to overcome this limitation, the ‘Peppermint Consortium’ was established within the breath community to carry out breath wash-out experiments and define reference values for a panel of compounds contained in the peppermint oil capsule. Here, we present a needle trap micro-extraction technique coupled with gas chromatography and tandem mass spectrometry for a rapid and accurate determination of alpha-pinene, beta-pinene, limonene, eucalyptol, menthofuran, menthone, menthol and menthyl acetate in mixed breath samples. Detection limits between 1 and 20 pptv were observed when 25 ml of a humidified standard gas mixture were loaded into a needle trap device at a flow rate of 10 ml min−1. Inter- and intra-day precisions were lower than 15%, thus confirming the reliability of the assay. Our procedure was used to analyse breath samples taken from a nominally healthy volunteer who was invited to swallow a 200 mg capsule of peppermint oil. Six samples were collected at various times within 6 h of ingestion. Analyte concentrations were not affected by the sampling mode (i.e. mixed vs. end-tidal fraction), whereas respiratory rate and exhalation flow rate values slightly influenced the concentration of the target compounds in breath samples.

Authors: Ding Zeya 
Published: November 2020

Abstract
Pollutant discharge standards are a technical legal norm. The essence of emission permit system is to meet the technical standards. Based on the classification of China’s two-level and four categories of water pollutant emission standard system, this paper analyses the poor performance of this system. The main reasons are the lack of special laws and regulations, the failure to break through key technical issues and backward management. In view of the key reasons, this paper discusses the feasible solutions. For example, to improve the total amount examination system of the pollutant discharge license, to formulate the relevant technical specifications for the management of the pollutant discharge license, to improve the drainage basin discharge standard with the goal of reaching the water quality standard, and to increase the punishment of illegal discharge.
Impact of Environmental Costs on Export Trade
Authors: Ouyang Ke 
Published: November 2020

Abstract
With the rapid growth of trade, the problem of environmental protection has become increasingly prominent. In the export trade, environmental costs are highly valued and become one of the enterprises important considerations for production and export in China. This paper analyzes the impact of environmental cost internalization and environmental regulation on export trade based on the related literature on environmental cost and export trade; using China’s one-time energy consumption data from 1997 to 2017 and 2001-2015 China’s major industrial pollution discharge data. It simply calculated the environmental costs based on energy consumption. The research results show that the impact of environmental costs on export trade is mainly reflected in the impact on trade advantages and export product structure. Whether it is internalization of environmental costs or reasonable environmental regulation, it has a positive effect on the protection of pollutants from export enterprises and the protection of environmental resources within a certain scope, but excessive environmental costs or environmental regulations will increase the production cost of export products, which is ultimately not conducive to the growth of export trade. The government needs to further strengthen the coordinated development of environment and export trade to build an environment-friendly trade power.

Optimizing the protection coordination of DGR (Directional Ground Relay) to overcome sympathetic disturbances and reduce energy not supplied on Toboali Substation
Authors: Siregar E M , Puriza M Y , Asmar  
Published: November 2020

Abstract
Along with the operation of the Toboali Substation, studies needed to improve reliability. The ground disturbance that occurs in a feeder can cause a sympathetic trip in another feeder and effect the blackout of Toboali system. This is due to the choice of loop operating patterns on feeders and buses that tend to be close together. From the results of simulation and optimization of directional ground relay coordination it was found that before the improvement of energy not supplied due to sympathetic disturbances on the Toboali system was 51,261 MWh/year and after the improvement of energy not supplied became 21,170 MWh/year. Expected this optimization of protection coordination improves reliability and reduces the energy not supplied due to sympathetic disturbances that occur in Toboali substation.

Published: November 2020

Abstract
Indonesia as a tropical country has high solar energy potential to generate power. Solar power plant (SPP) using Photovoltaic (PV) is suitable for power generation in a small power system, such as in several small islands in Eastern Indonesia since solar energy is easy to obtain there. The implementation of SPP for power generation needs an examination of energy yield to observe the performance ratio of SPP. Those parameters are important to study to further analyze the economic potential and feasibility of SPP development. This study estimates the performance ratio (PR) and potential energy yield of SPP in a small island in Eastern Indonesia through a self-developed program using MATLAB based Graphical User Interface (GUI). Moreover, this program also provides the levelized cost of energy (LCOE) calculation and land use optimization by readjusting the PV array configuration. According to the simulation result, the implementation of SPP in Eastern Indonesia has 85.4% and 23.54% for annual PR and capacity factor (CF) respectively. The simulation also shows that the optimum distance between PV strings produces higher annual energy yield and CF.

Characteristics of disturbance in frequency 9-150 kHz and harmonic distortion of the on-grid rooftop photovoltaic system for resistive and inductive load
Authors: Kurniawan S A , Sudiarto B 
Published: November 2020

Abstract
Direct current (DC) electricity generated from photovoltaic (PV) needs to be converted into alternating current (AC) using an inverter so that it could be combined with electricity from the grid. However, the inverter could distort the AC waveform in the form of harmonics and disturbance in the frequency range of 9-150 kHz caused by its switching characteristics which could reduce power quality, disrupt the power line communication (PLC) system, or other electronic equipment connected in the same network. This study investigated the characteristics of the disturbances in the frequency range of 9-150 kHz generated by the on-grid rooftop PV system and observed the correlation with harmonic distortion. There were three types of load used in this study, i.e. pure resistive loads, pure inductive loads, and combination of resistive-inductive loads. The measurements were carried out using an oscilloscope to obtain a time-domain signal, which later processed by Matlab using FFT to see its frequency response, and power quality analyzer to see its harmonic distortion. The results show that each type of load has different relationship characteristics between disturbance and harmonic distortion.
