One important component of education is the teacher. The teacher has an important role in teaching and learning activities in the classroom. Therefore, the role of a teacher is very necessary in supporting the achievement of educational goals in schools. In the learning process activities, a teacher is required to be able to master every material that will be taught and connect other knowledge that has a relationship with the material being taught. The length of a teacher's teaching experience can be a benchmark in assessing a teacher's explaining skills when carrying out learning. The purpose of this research is to find out whether there is an effect of length of teaching experience on a teacher's explaining skills. This study uses a type of quantitative research. The population in this study were teachers from several high schools in Malang Raya with a target of 30 teachers (Malang 9 State High School, Malang National High School, Muhammadiyah 3 Batu City High School, and Immanuel High School Batu City) selected randomly. The results of the study show that teachers have different backgrounds, coming from the field of education, some are non-educational, of course this also affects them. Thus, in this study it can be said that the length of teaching experience has no effect on the skills of explaining material during learning, but it is not significant.
Salah satu komponen penting pendidikan adalah guru. Guru memiliki peran penting dalam kegiatan belajar mengajar di kelas. Maka dari itu, peran seorang guru sangat diperlukan dalam menunjang pencapaian tujuan pendidikan di sekolah. Dalam kegiatan proses pembelajaran, seorang guru dituntut mampu menguasai setiap materi yang akan diajarkan serta menghubungkan pengetahuan lain yang memiliki hubungan dengan materi yang sedang diajarkan. Lama pengalaman mengajar seorang guru dapat menjadi tolak ukur dalam menilai keterampilan menjelaskan seorang guru pada saat melaksanakan pembelajaran. Tujuan penelitian ini untuk mengetahui apakah terdapat pengaruh lama pengalaman mengajar terhadap keterampilan menjelaskan seorang guru. Penelitian ini menggunakan jenis penelitian kuantitatif. Populasi dalam penelitian ini adalah guru beberapa SMA di Malang Raya dengan target 30 guru (SMA Negeri 9 Malang, SMA Nasional Malang, SMA Muhammadiyah 3 Kota Batu, dan SMA Immanuel Kota Batu) dipilih secara acak. Hasil penelitian menunjukkan bahwa guru memiliki latar belakang yang berbeda beda berasal dari bidang pendidikan ada juga yang non kependidikan tentunya hal tersebut juga mempengaruhi. Dengan demikian, pada penelitian ini dapat dikatakan bahwa lama pengalaman mengajar tidak berpengaruh terhadap keterampilan menjelaskan materi pada saat pembelajaran, namun tidak signifikan.

Published: June 2023

Background: Momordica charantia (M. charantia) has been used in traditional medicine for the management of complications associated with diabetes mellitus. Several phytochemicals with different pharmacological properties have been previously identified from the botanical; however, the mechanisms of actions of this plant vis-à-vis inhibition of non-enzymatic protein glycation are not known. This study aimed at understanding the putative mechanisms underlying the antiglycation properties of M. charantia extracts experimental and theoretical approaches.
Methods: The antiglycation properties of the plant were evaluated by studying the inhibitory actions of methanol and aqueous extracts on glucose-induced glycation of Bovine Serum Albumin (BSA) and protein aggregation. The mode of binding of identified phenolics of the botanical with BSA, amyloid beta-peptide (1-42) and 3D amyloid beta (1-42) fibrils were also investigated.
Results: The in vitro experimental properties of the extracts showed that the extracts could prevent inductions of protein glycation and protein folding. The molecular docking analyses revealed that phenolics had better binding affinities with chlorogenic acid showing the highest binding score (-7.13±0.04 kcal/mol) towards BSA than glucose and their respective interactions with BSA could prevent glucose-induced protein aggregation.
Conclusion: Consequently, the results of this study provide insight into the probable mechanisms of actions of the extracts of M. charantia against the inhibition of advanced glycation end products formation
Central Representation of Speech-in-Noise Perception: A Narrative Review
Authors: Emami Seyede Faranak , Shariatpanahi Elnaz 
Published: June 2023

Background and Aim: Speech-in-Noise (SIN) perception is one of the most important issues processed by human listeners. The purpose of speech tests is to determine the perceptual abilities of people in real life conditions; therefore, can speech tests in quiet be a valuable measure of this ability? Is the central representation of speech-in-quiet and SIN perception the same? This review study aimed to investigate the central representation of SIN perception in healthy individuals aged 14 to 60 years.
Recent Findings: Central representation of SIN perception is influenced by various peripheral factors and includes several neural processes. All auditory nerve fibers are stimulated by speech and noise. Low-frequency sounds play a much more important role than high-frequencies. The auditory nerve fibers that are stimulated by speech, respond only to fundamental frequencies (F0). The degree of neural synchronization that increases by noise and causes the simultaneous activity of these fibers, develops auditory processing. Large areas of the auditory cortex and its external parts (parietal, premotor, and mirror neurons) are stimulated. Larger groups of cortical nerve fibers are used for speech signals of the same family with significant ecological importance.
Conclusion: Central representation of SIN perception is not the same as in quiet. Speech perception tests in quiet cannot assess real-life perceptual abilities of people. SIN tests should be used routinely as a practical confirmatory test in audiology clinics. It is very necessary that the list of words and sentences required for SIN perception tests be prepared for different languages.

Published: June 2023

Air pollution is a serious matter that must be addressed promptly and quickly. One of the most dangerous pollutants in the air is PM2.5. This pollutant is particulates dust measuring 2.5 micrometers. PM2.5 can cause environmental and health problems such as acute respiratory infections, lung cancer, cardiovascular cancer, and premature death. Air pollution occurs in big cities such as the capital city of Indonesia, DKI Jakarta, which is the city with the highest PM2.5 levels in Indonesia. There are 6 six stations in DKI Jakarta that measure PM.2.5 level at 6 areas. The ordinary kriging is one of spatial methods that can be used to predict PM2.5 level in outside the existing stations, for example in the Pulogadung industrial area. This area was selected because there are many factories in this area that can increase levels of PM2.5 in the air. To predict the concentration of PM2.5 in one area could be done by calculating the surrounding PM2.5 concentrations that were not available to measure air quality. In study, we use mean an absolute percentage error ( MAPE ) value to evaluate Ordinary Kriging performance for predicting PM2.5 level in DKI Jakarta.

Published: June 2023

Machining titanium alloy (Ti6Al4V) used in orthopedic implants by conventional metal cutting processes is challenging due to excessive cutting forces, low surface integrity and tool wear. To overcome these difficulties and for ensuring high-quality products, various industries employ wire electrical discharge machining (WEDM) for precise machining of intricate shapes in titanium alloy. The objective is to make WEDM machining parameters as efficient as possible for machining the bio-compatible alloy Ti6Al4V using box-behnken design (BBD) and Non-dominated Sorting Genetic Algorithm II (NSGA II). A quadratic mathematical model is created to represent the productivity and the quality factor (MRR and surface roughness) in terms of varying input parameters, such as pulse active (Ton) time, pulse inactive (Toff) time, peak amplitude (A) current and applied servo (V) voltage. The established regression models and related prediction plots provide a reliable approach for predicting how the process variables affect the two responses viz MRR and SR. The effects of four process variables on both the responses were examined, and the findings revealed that the pulse duration and voltage has a major influence on the rate at which material is removed (MRR) whereas pulse duration influence quality (SR). The trade-off between MRR and SR, when significant process factors are included emphasizes the need for a reliable multi-objective optimization method. The intelligent metaheuristic optimization method named non-dominated sorting genetic algorithm II (NSGA II) is utilized to provide pareto optimum solutions in order to achieve high material removal rate (MRR) and low surface roughness (SR).

Abstract

Spread of multidrug-resistant Pseudomonas aeruginosa strains threatens to render currently available antibiotics obsolete, with limited prospects for the development of new antibiotics. Lytic bacteriophages (phages), the natural predators of bacteria, represent a path to combat this threat. In vitro directed evolution is traditionally applied to expand the phage host range or increase bacterial suppression in planktonic cultures. However, while 80% of human microbial infections are biofilm-associated, research towards targeted improvement of phages’ ability to combat biofilms remains scarce. Here, we describe an in vitro evolution assay that improves multiple phage parameters in parallel, while optimizing phage cocktail design by exploiting a bacterial phage resistance trade-off. The obtained evolved phages show an expanded host spectrum, improved antimicrobial efficacy under isothermal microcalorimetric monitoring and enhanced antibiofilm performance, as determined by RT-qPCR. Our two-phage cocktail revealed further improved antimicrobial efficacy without incurring dual-phage-resistance in treated bacteria. We anticipate this assay will allow a better understanding of phenotypic-genomic relationships in phages and enable the training of phages against other desired pathogens. This, in turn, will strengthen phage therapy as a treatment adjunct to improve clinical outcomes of multidrug-resistant bacterial infections.

Authors: Jeyakumar Hepsi Beaula Masilamani , Krishnamoorthy Jayakumar 
Published: June 2023

Abstract
The grooved grinding wheels are utilized to enhance the coolant supply to the grinding zone and reduce the heat throughout grinding, thus making the grinding performance more efficient. In the present study, Al2O3 grinding wheels of axial, circumferential and helical grooved wheels were used to grind the EN18 steel. The input parameters chosen for experiments were types of grooved grinding wheels, depth of cut with three different coolant techniques (Dry, Flood and MQL) and experiments were conducted as per L9 Taguchi orthogonal matrix. Output parameters measured for each experiment were grinding ratio (GR), material removal rate (MRR), grinding efficiency (GE), surface roughness (Ra), specific energy (SE), temperature and noise during surface grinding. The grinding performance of non-grooved grinding wheels was compared with a grooved wheel. The results showed that using grooved grinding wheels increases all the grinding performances when compared to the non-grooved grinding wheel. The helical grooved wheel with MQL combinations reduced the temperature, sound, surface roughness and specific energy from 35.8 to 32.1 °C, 86.9 to 80.7 dB, 1.584 to 0.258 µm and 0.173 to 0.054 kJ/mm2 respectively. At the same time, the MRR, HRC, GR and GE were improved using grooved grinding wheels along with MQL from 0.432 to 1.37 mm3/s, 58.5 to 61.5 HRC, 1.77 to 4.567 and 10.26 to 43.9% respectively. Finally, the optimum grinding parameter combination was identified from a helical grooved wheel in all grinding performances. Finally, the performance of the helical grooved wheel was compared with non-grooved wheels. SEM images were taken to understand the surface finish and defects on the ground surfaces for the different wheels with coolants.
Steering control and stability analysis for an autonomous bicycle. Part II. Experiments and a modified linear control law

Published: June 2023

Abstract
This paper presents experimental results to verify the reduced dynamics modeling and stability analysis of an autonomous bicycle, following the theoretical framework presented in Part I. A self-fabricated autonomous bicycle is introduced, and experiments are conducted to verify its stability in uniform straight motion (USM) and uniform circular motion (UCM). While the experimental results are qualitatively consistent with the theoretical findings, they also reveal that the stability of the bicycle is affected by uncertainties in the real system, primarily stemming from the drift error of the gyroscope sensor used to measure the bicycle's lean angle. Parameter uncertainty analysis confirms the gyroscope drift as the main source of uncertainty. To compensate for this drift error, a modified linear control law with a time-varying intercept term is proposed. This results in a three-dimensional reduced dynamic system governing the bicycle's controlled motion. Theoretical analysis and experiments demonstrate that the bicycle under the modified linear control law achieves stable USM and UCM with a desired steer angle, and exhibits an interesting phenomenon of a limit cycle motion when the control parameters are set such that the trivial relative equilibrium becomes unstable through a supercritical Hopf bifurcation.

Abstract
Hepatitis A virus (HAV) endemicity in the Philippines ranges from moderate to high, with estimated annual hepatitis A incidence rate in the Philippines of 0.4–0.6 cases per 100,000 population. Despite this, health risks related to local seafood consumption are associated with red tide or mass fish kill. However, government agencies should consider the safety of local shellfish and culture sites to HAV. This article examines the current trends relevant to the presence of HAV along the local shellfish supply chain, including production levels, microbial concentration, consumer behavior, and food safety regulations. Despite the susceptibility of local shellfish to HAV, the study identified crucial data gaps: 1) reliance on bacterial indicators, 2) absence of monitoring records for HAV concentration in local shellfish products and culturing sites, and limited studies regarding the effect of local cooking practices on HAV inactivation. The synthesis of this analysis will guide the national food safety risk managers in addressing the
Experimental investigation of the capacity of carbon nanotubes to absorb organic pollutants

Published: June 2023

Abstract

Dissolved organic pollutants caused by paints, detergents, herbicides, and toxins cannot be removed from the water body through conventional treatment processes such as filtration. Activated carbon is one of the effective substances to obliterate these contaminants from water. The carbon nanotubes (CNTs) have a much higher ability to decompose organic pollutants; however, using the slurry form is undesirable due to the removal requirement at the end of the treatment process. In the present study, upgraded CNTs attached to particles of sand filters (CNTsand) were synthesized and applied to omit dissolved organic pollutants. The results revealed the high capacity of the CNTsand to wipe organic contaminants. The column test with natural water compared to the synthesized water had a more extended breakpoint, higher adsorption capacity, and consequently, further removal efficiency, such that for the surface area loading rate of 4.8 ml/min, the breakpoint increased from 739 minutes to 936 minutes as well as the volume of passed water grew from 3546 ml to 4493 ml. Therefore, the maximum adsorption capacity was enhanced from 67.3 mg/g to 89.5 mg/g. Finally, the adequacy and efficiency of the upgraded nanotube coating on sand grains to remove organic pollutants were confirmed.
An inverse Q filtering method with efficient Q estimation using a shallow neural network
Authors: Wu Jizhong , Shi Ying , Wang Kexin 
Published: June 2023

Abstract
Inverse Q filtering is a common tool in seismic processing that can be used to improve the resolution of poststack imaging data. However, it is difficult to obtain the Q value conveniently and precisely, which limits the precision and industrial application range of inverse Q filtering. In this study, a set of technology schemes based on a BP neural network is proposed to quickly acquire the Q field so that inverse Q filtering has the ability to adapt to inhomogeneous Q values. Based on the powerful nonlinear solving ability of the BP neural network, the functional mapping relationship between the Q value and spectral information of seismic data is established, which improves the anti-noise ability of Q value prediction. The application effect of the model and actual data verifies the effectiveness of the proposed scheme.
