Simultaneous online determination of S, Cl, K, Na Zn and Pb release from a single particle during biomass combustion Part 2: Results from test runs with spruce and straw pellets

To gain better insight into inorganic element release processes, test runs with a specially designed single particle reactor connected with an inductively coupled plasma mass spectrometer (ICP-MS) have been performed. Relevant combustion related parameters such as mass loss during thermal degradation, temperature development of the particle (surface and center), and composition of released gases were recorded. By coupling the reactor to an ICP-MS, time-resolved release profiles of relevant aerosol forming elements (S, Cl, K, Na, Zn, and Pb) were determined. Targeted and controlled interruptions of the experiments (quenching) after a certain time were performed to validate reactor performance and reliability of the measurements. Test runs with softwood and straw pellets (8 mm in diameter and about 20 mm in length) were performed at reactor temperatures of 700, 850, and 1000 °C under oxidizing conditions (5.6 or 4.2 vol % O2). These test runs have revealed that the release ratios of volatile and semivolatil.
Stellar Rotation in the K2 Sample: Evidence for Modified Spin-down

We analyze light curves of 284,834 unique K2 targets using a Gaussian process model with a quasi-periodic kernel function. By cross-matching K2 stars to observations from Gaia Data Release 2, we have identified 69,627 likely main-sequence stars. From these we select a subsample of 8977 stars on the main sequence with highly precise rotation period measurements. With this sample we recover the gap in the rotation period−color diagram first reported by McQuillan et al. While the gap was tentatively detected in Reinhold & Hekker, this work represents the first robust detection of the gap in K2 data for field stars. This is significant because K2 observed along many lines of sight at wide angular separation, in contrast to Kepler’s single line of sight. Together with recent results for rotation in open clusters, we interpret this gap as evidence for a departure from the t −1/2 Skumanich spin-down law, rather than an indication of a bimodal star formation history. We provide maximum likelihood estimates and uncertainties for all parameters of the quasi-periodic light-curve model for each of the 284,834 stars in our sample.
Laboratory evaluation of two isolates of Meterhizium anisopliae and Beauvaria bassiana to control infesting by Trogoderma granarium (Coleoptera: Dermestidae) larvae

Trogoderma granarium Everts (Khapra beetle) is a serious pest of stored barley and wheat worldwide. The current research evaluates the efficacy of local isolates of Meterhizium anisopliae and Beauvaria bassiana compared to an imported isolates when khapra larvae sprayed with concentration of later isolates under laboratory condition, mortalities were recorded for more than two weeks after treatment. Results demonstrated that the larvae were more susceptible to the local isolates of the two fungi than the imported isolates. Cumulative mortalities were 86.67 and 50 when larvae sprayed with 109 conidia/ml of local and imported isolates of M. anisopliae respectively, and 86.67 and 66.67 when larvae sprayed with 109 conidia/ml of laocal and imported isolates of B. bassiana respectively after two weeks. The findings of the current study clearly showed that the local isolates caused higher mortalities than the imported one so they may be used as a good candidates for pragmas of integrated pest management of stored grain pests.

Determination of the Antioxidant Activity and Bioactive Compounds of Mulberry Fruit Extracts

White mulberry (Morus alba L.) is a berry native to China which fruit is usually eaten fresh or after processed. Its bioactive compounds vary depending on species, cultivation, location and others. In this study, the total flavonoids content, total phenolic content, total anthocyanins content and antioxidant activity of Morus alba L. fruit grown in Tuaran, Sabah were analyzed. Fruit was extracted with 60°C hot water and 80% ethanol, while the total bioactive compounds analysis utilized aluminum chloride, Folin-Ciocalteu and pH differential method in determining the flavonoids, phenolic, and anthocyanins content. Their antioxidant activity was determined using Free Radical Scavenging 2.2-Dyphenyl-1-Pikrilhidrazil (DPPH), Ferric Reduction Antioxidant Power (FRAP) and Radical Cation 2,2’-Azino-bis (3-ethylbenzthiazoline-6-sulphonic acid (ABTS) assay. As a result, significantly higher (p < 0.05) content of total flavonoids (104.34 mg QE mg−1), phenolic (1.21 mg GAE mg−1) and anthocyanins (0.74 mg c-3-ge mg−1) were obtained from ethanolic extract than the hot water extract. Also, significantly higher (p < 0.05) antioxidant activity was observed in ethanolic extract for DPPH (0.50 mg mL−1), FRAP (3.74 mm Fe (II) g−1) and ABTS (6.05 mg AEAC g−1). Data showed that ethanol solvent (80%) is a better solvent for Morus alba L. fruit’s extraction.
Thermonuclear 19F(p, α)16O Reaction Rate Revised and Astrophysical Implications

We have calculated the thermonuclear 19F(p, α γ )16O reaction rate in a wide temperature region of 0.001–10 GK by re-evaluating the available experimental data. Together with recently evaluated 19(p, α 0)16O and 19(p, α π )16O data, we have derived a new total reaction rate of 19F(p, α)16O using a Monte Carlo technique. The present rate is larger than the NACRE recommended one by factors of 36.4, 2.3, and 1.7 at temperatures of 0.01, 0.05, and 0.1 GK, respectively. This is because we have considered the enhanced low-energy astrophysical S factors in the (p, α γ ) channel, owing to the interference effect between an 11 keV resonance and the well-known 323 keV resonance. It shows that the (p, α γ ) channel dominates the total rate over the entire temperature region, except for a narrow region of 0.05–0.12 GK where the (p, α 0) channel dominates, contrary to the previous conclusion. We have investigated the impact of the 19F(p, α)16O reaction rate using a simple parametric model of extra mixing in low-mass AGB stars, which would lower the fluorine abundance produced and observed in these stars. However, models considering different temperature profiles and more sophisticated approaches, such as extra mixing induced by magnetic fields, are needed to verify the results of our preliminary tests. Interestingly, our new rate has a strong impact on destruction of 19F in the CNO cycle at low temperatures of 0.02–0.03 GK, and this general behavior needs to be analyzed further.
A Computational Study on Substituted and Unsubstituted Mono and Diazaanthracenes

Substituted (F, Cl, OH, and NO2 ) diazaanthracene derivatives have been considered theoretically to obtain information about their stabilities and aromaticities. The expected decrease of aromaticity of parent anthracene by mono or diaza substitution has been compensated by substitution of one of the hydrogens of the system by an electronegative atom. The position of the substituent has been proved to be strongly effective on the aromaticity of the structure such that, the aromaticity is enhanced when the susbtituent is closer to the aza points.
The importance of health co-benefits under different climate policy cooperation frameworks

Reducing greenhouse gas emissions has the ‘co-benefit’ of also reducing air pollution and associated impacts on human health. Here, we incorporate health co-benefits into estimates of the optimal climate policy for three different climate policy regimes. The first fully internalizes the climate externality at the global level via a uniform carbon price (the ‘cooperative equilibrium’), thus minimizing total mitigation costs. The second connects to the concept of ‘common but differentiated responsibilities’ where nations coordinate their actions while accounting for different national capabilities considering socioeconomic conditions. The third assumes nations act only in their own self-interest. We find that air quality co-benefits motivate substantially reduced emissions under all three policy regimes, but that some form of global cooperation is required to prevent runaway temperature rise. However, co-benefits do warrant high levels of mitigation in certain regions even in the self-interested case, suggesting that air quality impacts may expand the range of possible policy outcomes whereby global temperatures do not increase unabated.
Numerical Modelling Of The Effect Of Temperature And Thickness On The Electrical Properties Of Polycrystalline Semi-Conductor Solar Cells [CdTe and Cu(In,Ga)Se2(CIGS)] Using One Dimensional Device Simulation

A numerical simulation program SCAPS 1D (solar cell and capacitance simulator) was used in the simulation of CdTe and CIGS solar cells. We concentrated on the effect of temperature and thickness on the electrical properties of CdTe and CIGS solar cells and the agreement between the simulations and measurements was shown and discussed using SCAPS 3.3. 00. The influences of temperature and thickness on CdTe and CIGS solar cells were investigated by I-V measurements. The simulated efficiencies for CdTe and CIGS solar cells at 300K were observed to be 16.03% and 16.54% which compare very well with the measured efficiencies 10.72% for CdTe and 15.96% for CIGS solar cell at same temperature. It was found out that as temperature and thickness increases from (200 – 400)K and (2 – 6μm, efficiencies decrease from 18% to 10% for CdTe and 20% to 8% for CIGS from (250 – 400)K and (1 – 5μm respectively.
Experimental and Numerical Study on Laminar Flame Characteristics of Methane Oxy-fuel Mixtures Highly Diluted with CO2

An experimental and numerical study on laminar flame characteristics of methane oxy-fuel mixtures highly diluted with CO2 was conducted using a constant volume chamber and CHEMKIN package. The effects of high CO2 dilution on combustion chemical reaction, flame instability, and flame radiation of CH4/CO2/O2 mixtures were studied. The laminar burning velocities of CH4/CO2/O2 mixtures decrease with the increase of the CO2 fraction. CO2 directly participates in the chemical reaction through the elementary reaction OH + CO = H + CO2 and inhibits the combustion process by the competition of the H radical between the reverse reaction of OH + CO = H + CO2 and the reaction H + O2 = O + OH. This effect is more obvious for highly diluted CO2 in the case of CH4/CO2/O2 mixtures. CO2 suppresses the flame instability by the combined effect of hydrodynamic and thermal-diffusive instabilities. The radiation of CH4 oxy-fuel combustion is much stronger than that of CH4/air combustion mainly because of the existence of a lar.
Recent Progress of Fused Deposition Modeling (FDM) 3D Printing: Constructions, Parameters and Processings

Fused Deposition Modeling (FDM) is the most widely used 3D printing technique. The use and development of FDM cover various fields such as automotive, airplane, to biomedical. Many studies have been conducted to study the effect of various printing parameters and post-processing treatment on the performance of printing results with FDM. This literature study aims to compile and summarize the latest studies related to the effect of FDM process parameters and post-processing treatment as well as prospects and challenges. The review found that the combination of several synchronized parameter processes can produce parts that are printed better because several parameters are interrelated and can complement to each other. In addition, the quality of FDM printing results is generally found to be better with post-processing treatment although it requires more effort that might not always be feasible for some applications.
Driver drowsiness detection system with opencv and keras

Drowsiness of the drivers is the principal cause of injuries in the world. Because of loss of sleep and tiredness, drowsiness can occur even as riding. The first-rate manner to keep away from accidents because of drivers’ drowsiness is to come across drowsiness of the driving force and warn him before fall into sleep. To discover drowsiness many techniques like eye retina detection, facial function recognition has been used. Here on this paper, we suggest a way of detecting motive force drowsiness, the usage of eye retina detection and pulse charge detection of the driving force. On this record, we endorse an extra accurate drowsiness detection approach which is a hybrid technique of eye retina detection and pulse sample detection.
Aerodynamic Characteristics of Baseball and Tennis Ball using CFD Analysis

The objective of the project is to determine the aerodynamic characteristics of baseballs and tennis balls using Computational Fluid Dynamics (CFD) methods. Most realistic initial and boundary conditions are used to simulate each type of ball and to identify key design aspects that can be applied and modified to enhance the performance of the ball and hence improve the game. The basic conservation equations in fluid dynamics are applied to the domain of study to plot the results. For the inlet, different values of velocity based on the motion of the ball in the game were given. A moderate value of surface roughness was given to model the effects of change in the surface between the two balls and the delay in boundary layer separation subsequently affecting the distance travelled by the ball was seen. By observing the values of lift and drag coefficients we can validate computational results with experimental results obtained from reference journals, thus proving that computational simulation has a place in predicting the trajectory and behaviour of moving balls in real-time. The integration of spin in the simulation also yielded results that showcased the Magnus effect, this visualization is generally not observable on experimental methods since it involves complex processes to simulate spin, hence the trajectory of balls under different shots and pitches has been observed. We further developed an idea that could also be used to determine the trajectory of a dual-axis spinning ball. This would help in building the performance of athletes in the game.
A practical approach to non-spectral interferences elimination in inductively coupled plasma optical emission spectrometry

Matrix effects and practical possibilities of reducing accompanying non-spectral interferences in inductively coupled plasma optical emission spectrometry (ICP-OES) were studied for microconcentric Micromist, concentric and V-groove nebulizers (VGN) coupled with two cyclonic spray chambers of different sizes. The effect of a wide scale of interferents and mixtures thereof in the concentration range of up to 2 mass % (Na, Ca, Ba, La, urea) or up to 20 vol. % (nitric acid) on the analysis of Cd, Cu, K, Mg, Mn, Pb and Zn was investigated in terms of their analytical recovery and Mg(II) 280.27 nm/Mg(I) 285.29 nm line intensity ratio. Recoveries of ionic lines were lower than those of atomic lines (37–102 %) depending on the matrix concentration. The Mg(II)/Mg(I) ratios were found to be 12–15 and they slightly decreased as the matrix load increased. Exceptional behavior of pure La matrix, steeply lowering the recoveries and Mg(II)/Mg(I) ratios was observed. A Micromist nebulizer coupled with a small inner volume spray chamber provided the highest recoveries (94–102 %), lowest matrix effects across the matrix loads and, compared to others, the least significant dependence without worsening of the analytical characteristics (recoveries, signal background ratios and the Mg(II)/Mg(I) ratios) across the studied matrices.
Network Characterization of Goods Movement in Indonesia

Network characterization of goods movement is particularly important to estimate needs and accurate management for freight transportation. The present study aims at characterizing the network of goods movement in Indonesia and examining the effectiveness of network characterization for prediction purpose. A network approach using RStudio was applied. It was found that the network of goods movement in Indonesia is characterized by weak inter-provincial goods movement, scale-free network, disassortative, having rich-club phenomenon, and having a core-periphery structure in which Sumatera Barat (West Sumatera) and Jawa Barat (West Java) appears to be the cores of the network. The findings also demonstrate that the prediction model developed by characterization performs better and can explain, on average, 39% of the variances. The prediction models for chemicals, fuel, meat and livestock, fish, crude oil, and fertilizer, have even better capability to explain variances in the volumes of goods movement by more than 60%. Potential avenues for future research are also discussed.

Traffic Detection Program using Image Processing and the 1997 Indonesian Highway Capacity Manual (MKJI)

As a part of transport planning and assessment, traffic volume is essential data. However, many Indonesian’s transports engineers, in particular, still use manual traffic counting to collect data series for traffic volume in 24 hours or more. This method is considered inefficient and expensive along with technological developments in this modern era. The purpose of this study tries to simplify the traffic counting method by developing an automatic vehicle detection program based on the 1997 Indonesian Highway Capacity Manual (MKJI) classification. The application that used in this study is KS Traffic Analyzer as open-source code traffic counting based on Java and OpenCV library. This application then modifies as MKJI 1997 vehicles classification to measure traffic data in urban and rural road using drone quadcopter. This tool using Gaussian Mixture Model (GMM) method for processing images/videos of traffic based on the background and foreground. Traffic footage was tested at different times, height, and angle of shooting. The accuracy was measured by comparing the volume from the program and manual counting. The results showed that the best accuracy between real traffic volume and automatic counting in the program is in the urban street with the best accuracy reached 93.66% which was taken video in the morning and the height is 5 m. This result of this study also answers the function of road performance based on volume per capacity.
The Formation of C3O3H6 Structural Isomers in the Gas Phase through Barrierless Pathways: Formation and Spectroscopic Characterization of Methoxy Acetic Acid

Gas phase formation processes feasible at low temperatures are determined theoretically for 38 isomers obeying the C3O3H6 empirical formula, one of them, the simplest ketose dihydroxyacetone, has been observed in gas phase sources. A preliminary search for isomeric forms first targets ethoxy formic acid (C2H5–O–COOH) as the most stable isomer followed by lactic acid. Profiles corresponding to the minimum energy pathways reveal that the favored conformers of 14 of these isomers can be formed in the gas phase through 29 barrierless processes involving the OH*, CH3O*, HCO*, CH3*, CH2OH, HCOO*, and OHCO* radicals, all of them observed in the interstellar medium. Kinetic rates are provided at 200, 298, and 500 K, confirming the suitability of 16 processes at low temperatures. Faster processes involve the OH hydroxyl radical whereas, to a lesser degree, the processes involving the HOCO radical and the methoxy methyl radical CH3O*, are quite significant. Spectroscopic parameters (rovibrational and torsional) are obtained for methoxy acetic acid (CH3–O–CH2COOH) for which two low-lying isoenergetic conformers can be produced from the CH3OCH2* radical predicted to be a precursor of abundant observed molecules. Profiles and spectroscopic properties make methoxy acetic acid a good candidate to be detected in the gas phase of extraterrestrial sources.

The low-noise and low-power amplifier, an important part of ECG recordings, remains a vital challenge in the biomedical instrumentation amplifier field. This paper describe a method of using the capacitive feedback structure and the MOS-bipolar pseudo-resistor to reject the DC offset and amplify signals down to the milli-hertz range. This study used the noise efficiency factor (NEF) to quantify the tradeoff between power and noise. Fabricated in a 180 nm CMOS process, the amplifier consumes 1.44 µW, and achieves the input referred noise of 3.89 µVrms The calculated NEF is 18.07, while the corresponding to common-mode rejection ratio (CMRR) is 87.72 dB. The device achieves low-noise, low-power and appropriate CMRR, which provides a reference for the design of biomedical instrumentation amplifier.
