Enhancing the Radar Cross-Range Resolution in Ultra-Fast Radar Scans by Utilizing Frequency Coded Sub-Channels

This contribution handles a single-channel radar method that utilizes frequency-coded sub-channels for enabling cross-range resolution. Because of the sub-channel coding, the whole area of interest (AOI) is scanned within a single radar measurement. To further enhance the cross-range resolution, the sub-channels’ antenna beams are overlaid in this work, resulting in multiple coding signatures. Next to the operation theory, hardware components, such as coding filters and antennas, as well as signal processing methods, are presented and discussed in detail. A final measurement campaign that investigates several radar scenarios reveals high detection properties and proves the applicability of the proposed radar method.
Environmental sustainability strategies and impacts:A case study in Northport, Klang, Malaysia

Environmental sustainability, a focal point for the government of Malaysia, is also important in developing business sustainability for businesses including ports. Following this, the research objectives of this study were threefold: 1) investigating the impact of strategies implemented by Northport, Klang in order to be environmentally sustainable, 2) ascertaining the priorities of these strategies and 3) determining the barriers or challenges faced by the port in its efforts of implementing the strategies. Using qualitative research design, data was collected through semistructured interview with the officers in charge of environment at the Northport, Klang, Malaysia. Findings indicate that strategies implemented by the port have been successful in their efforts to reduce emission and improve air quality, a big step in being environmentally sustainable. Several criteria were used to prioritize the strategies, chief among them being implementation cost and time, maintenance cost and reduction of carbon emission. In terms of priority, the first strategy was operational strategy in terms of vessel speed reduction initiative, followed by infrastructure and equipment strategy with equipment and engine replacement and emission control technology and lastly, image improvement strategy with the initiative of the implementation of green building. The biggest barrier in implementing these strategies was cost.
Studies on the Antiliver Injury of Effective Parts from Saururus chinensis by Rats and Mice Model In Vivo

The aim of this study was to evaluate the pharmacodynamics of the effective parts from Saururus chinensis (EPS) in vivo. The antihepatic fibrosis and injury effects of EPS were investigated with the following four model animals including the effect on Wistar rats with liver fibrosis induced by complex factors, mice with acute liver injury induced, respectively, by carbon tetrachloride and alcohol, and Sprague-Dawley (SD) rats with acute liver injury caused by D-galactosamine hydrochloride. The pharmacodynamics results showed that the rats' oral administration of EPS can significantly inhibit the formation of liver fibrosis in rats caused by complex factors and has significant preventive and therapeutic effects on acute liver injury caused by various factors as shown by decreased levels of serum biochemical indicators and improved pathological grade. Taken all together, our findings showed that EPS exhibits potent activities and should be considered a good option and an additional source of natural compounds for the treatment of hepatic fibrosis and hepatic injury.
Digital Natives and online learning in police students

Background. Although not a novelty in education, online teaching and learning has come to the fore with the COVID-19 pandemic. As opposed to the time before this crisis, when it had been an option for certain categories of learners, with the pandemic going on, there has been emergency and forced shift to online environment which has had its impact on both teaching and learning. Purpose. This qualitative research was aimed to investigate the perception of the students of the University of Criminal Investigation and Police Studies (UCIPS) in Belgrade regarding the English Language 2 course primarily, but also regarding their online education in general. The questionnaire was designed, consisting of 11 multiple choice and open-ended questions combined. The goal was to investigate the opinions and experiences of the UCIPS students in order to get an in-depth insight into the problems related to online education. Results. The results suggest that in addition to the initial practical problems related to equipment and technology, the students faced other problems as well, including the lack of concentration, insufficient interaction, etc. However, there are some positive results: the students reported the overall satisfactions with the academic outcomes, and in their opinion the optimum way of teaching/learning would be a blended model. Conclusion. Our sample of Digital Natives have demonstrated the ability to recognize the main characteristics of online learning, its advantages and disadvantages, but also the objective and subjective aspects of problems. Although it was not a matter of choice for them, they have adapted to it well, as well as their teachers. The challenges however remain for both students and teachers in order for online education to be accepted even better in the future.
Analysis of Apple Fruit (Malus × domestica Borkh.) Quality Attributes Obtained from Organic and Integrated Production Systems

The aim of this study was to compare total phenolic content (TPC), radical-scavenging activity (RSA), total anthocyanin content (TAC), sugar and polyphenolic profiles of two apple cultivars (‘Discovery’ and ‘Red Aroma Orelind’) from organic and integrated production systems in climatic conditions of Western Norway. Sixteen sugars and four sugar alcohols and 19 polyphenols were found in the peel, but less polyphenols were detected in the pulp. The peel of both apples and in both production systems had significantly higher TPC and RSA than the pulp. The peel from integrated apples had higher TPC than the peel from organic apples, while organic apples had higher TAC than the integrated. Sucrose and glucose levels were higher in organic apples; fructose was cultivar dependent while minor sugars were higher in integrated fruits. The most abundant polyphenolic compound in the peel of the tested cultivars was quercetin 3-O-galactoside, while chlorogenic acid was most abundant in the pulp. Regarding polyphenols, phloretin, phloridzin, protocatechuic acid, baicalein and naringenin were higher in organic apple, while quercetin 3-O-galactoside, kaempferol 3-O-glucoside, chlorogenic acid and syringic acid was higher in integrated fruits. In conclusion, organic ‘Discovery’ and integrated ‘Red Aroma Orelind’ had higher bioavailability of health related compounds from the peel and the pulp.
Pengukuran Nilai Densitas pada Minyak Pelumas Sepeda Motor dengan Gelombang Ultrasonik

—Density is a measure of the mass of each unit volume of an object; the higher the density of an object, the greater the mass of each volume. The density value can be used to distinguish the characteristics of lubricating oils that are prone to contamination with solid or liquid particles. The density value is also affected by changes in temperature; the higher the temperature of the lubricating oil, the smaller the density value. The regulations in force in Indonesia with the ASTM D1298-12b standard density test method state that the measurement uses a temperature of 15℃. In this study, the density measurement value was obtained at a temperature of 28℃ so it required a value conversion using the ASTM 53B table about the density correction factor. The technique of testing the material without damaging the test object using an ultrasonic sensor is used to measure the density value of motorcycle lubricating oil. Measurements are made by transmitting a 3 MHz ultrasonic trigger signal that can penetrate each medium with different characteristics. The received echo signal produces information about the distance between the medium, the speed of sound, and the acoustic impedance. The results of the measurement of 11 samples of motorcycle lubricating oil both in new and used conditions using the acoustic impedance method resulted in an accuracy of 93,6% or 0,058 kg/dm 3 when compared to the value measured using a pycnometer. The MPX-2-C sample measurement showed the lowest error of 0,41% or 0,004 kg/dm 3 .
Molecular Epidemiology of Antibiotic Resistance Genes and Virulence Factors in Multidrug-Resistant Escherichia coli Isolated from Rodents, Humans, Chicken, and Household Soils in Karatu, Northern Tanzania

The interaction of rodents with humans and chicken in the household environment can facilitate transmission of multidrug-resistant (MDR) Escherichia coli (E. coli), causing infections that are difficult to treat. We investigated the presence of genes encoded for carbapenem, extended spectrum beta-lactamases (ESBL), tetracycline and quinolones resistance, and virulence among 50 MDR E. coli isolated from human (n = 14), chicken (n = 12), rodent (n = 10), and soil (n = 14) samples using multiplex polymerase chain reaction (PCR). Overall, the antimicrobial resistance genes (ARGs) detected were: blaTEM 23/50 (46%), blaCTX-M 13/50 (26%), tetA 23/50 (46%), tetB 7/50 (14%), qnrA 12/50 (24%), qnrB 4/50 (8%), blaOXA-48 6/50 (12%), and blaKPC 3/50 (6%), while blaIMP, blaVIM, and blaNDM-1 were not found. The virulence genes (VGs) found were: ompA 36/50 (72%), traT 13/50 (26%), east 9/50 (18%), bfp 5/50 (10%), eae 1/50 (2%), and stx-1 2/50 (4%), while hlyA and cnf genes were not detected. Resistance (blaTEM, blaCTX-M, blaSHV, tetA, tetB, and qnrA) and virulence (traT) genes were found in all sample sources while stx-1 and eae were only found in chicken and rodent isolates, respectively. Tetracycline resistance phenotypes correlated with genotypes tetA (r = 0.94), tetB (r = 0.90), blaKPC (r = 0.90; blaOXA-48 (r = 0.89), and qnrA (r = 0.96). ESBL resistance was correlated with genotypes blaKPC (r = 0.93), blaOXA-48 (r = 0.90), and qnrA (r = 0.96) resistance. Positive correlations were observed between resistance and virulence genes: qnrB and bfp (r = 0.63) also blaTEM, and traT (r = 0.51). Principal component analysis (PCA) indicated that tetA, tetB, blaTEM, blaCTX-M, qnrA, and qnrB genes contributed to tetracycline, cefotaxime, and quinolone resistance, respectively. While traT stx-1, bfp, ompA, east, and eae genes contributed to virulence of MDR E. coli isolates. The PCA ellipses show that isolates from rodents had more ARGs and virulence genes compared to those isolated from chicken, soil, and humans.
Soil Liquefaction Analysis Based on Geotechnical Exploration and in Situ Test Data in the Tabriz Metro Line 2

Liquefaction is one of the most important and complex topics in geotechnical earthquake engineering. During this phenomenon, pore water pressure increases as long as it will be equal to confining stresses. Hence, the effective confining stress becomes zero and the soil will not have any shear resistance. As a result the soil mass is unstable and causes much destruction. In this research, according to information from boreholes of Tabriz Urban Train Line 2 all required parameters including total stresses, pore water pressures and effective stresses, the results according to soil type and water depth for all 53 preliminary boreholes were collected and evaluation of the liquefaction potential assessment based on energy standard penetration resistance test (SPT) has been compared. The depth of standard penetration resistance test (Nspt) in which the results were not available, the interpolation method were used for all layers. For evaluation of liquefaction potential based on (SPT) method the latest techniques offered by Idriss Boulangr (2008) were used. In this paper, calculations are presented for an earthquake of 7.5 in the scale of Richters. Then the safety factor against liquefaction is computed by these methods for several boreholes at different depths, and liquefaction risk evaluation has been done by Iwasaki method. At last by comparison of 3 sample boreholes and considering difference between them it can be concluded that some areas of Tabriz metro line 2 is located in perfect liquefaction conditions.
Assessing the Impact of Using Design Patterns of Enterprise Application Architecture

For successful businesses that develop software, software quality cannot be an exception it must be the requirement. Design patterns are solutions to general problems that software developers face during software development. These solutions have generally been developed and evolved over time. It has been claimed that the design patterns have an impact on the quality of enterprise application architecture. In this paper we try to assess the impact of using design patterns of enterprise application architecture. We focused the scope of this thesis on complexity and maintainability. We chose several well-established measures for complexity and based on those measures we built three maintainability models. We chose four Web Presentation patterns as described by Martin Fowler in his work titled Pattern of Enterprise Application Architecture, namely: a) Model View Controller architectural pattern, b) Page Controller, c) Front Controller, and d) Template View. For the purpose of this research we designed and developed four cases as a simple enterprise application. We based all four cases on the same requirements and the same technology but with a different set of Web Presentation patterns. We compared the results after collecting the measures for complexity and maintainability for each case. The comparison shows that: • the Model View Controller architectural pattern might have a positive impact on complexity and maintainability; • using the Front Controller pattern instead of the Page Controller pattern in Model View Controller architecture might not have an impact on complexity and maintainability; • when we use the Front Controller pattern instead of the Page Controller pattern in not Model View Controller architecture then the impact on complexity and maintainability might be positive. This paper is not a complete evaluation of the impact of using design patterns of enterprise architecture, but it certainly is an introduction to design patterns and to measuring software qualities. We measured the results for a specific enterprise system by using a specific programming language, thus there is no generalization.
Future Land Precipitation Changes Over the North American Monsoon Region Using CMIP5 and CMIP6 Simulations

Changes in the North American Monsoon (NAM), a circulation system that transports moisture into western Mexico and the southwest U.S., can have substantial impacts on water resources and agriculture. Here, we utilize future projections from Phase 6 and 5 of the Coupled Model Intercomparison Project (CMIP) to assess monthly changes in land precipitation and the leading mechanisms resulting from anthropogenic climate change. Historical CMIP6 simulations of seasonal precipitation demonstrate skill in reproducing NAM rainfall, but mimic precipitation biases observed in previous CMIP generations. Future climate projections from the SSP5‐8.5 pathway produce reductions in precipitation that persist throughout the monsoon season (June–August) but are balanced by precipitation increases during the late monsoon season (September–October) but are not shown in CMIP5 projections. Atmospheric moisture budget analysis reveals that early monsoon rainfall deficits are associated with a combination of greater evaporative demand, a negative dynamic response of vertical moisture advection, and anomalous subsidence. Increases in late monsoon season rainfall are attributed to a positive change in the dynamical term of vertical moisture advection and increases in upward motion. Although minimal changes in total land NAM rainfall are observed, seasonal shifts and the persistence of drier conditions can have significant ecological and societal consequences.
Pneumatic gear shifter analysis

Conventional design of transmission gear shifter is basically consists of mechanical linkage of gear lever attached on the side of motorcycle engine with pivot directly connected to the gear shifting mechanism. Shifting up and down of gear positions are performed by moving foot or toe upward and downward on the lever respectively. For disable rider (rider requires special need), shifting gear for manual transmission type of motorcycle with or without clutch system is difficult. In this research, a pneumatic gear shifter is designed and tested. It consists of pneumatic circuit with actuator, tanks and air compressor. The movement of gear lever is performed by the pneumatic actuator. Pneumatic tanks are installed to achieve optimum pressure. It also controlled by wireless system for convenient purpose and buttons installed at the handle. Simple experiment is performed to measure the force for each gear position.

Objective Comparison of Achievement Motivation and Competitiveness among Semi-Professional Male and Female Football Players

The aim of this study was to examine differences in achievement motivation (measured with the Objective Achievement Motivation Test, OLMT, Schuhfried®) and competitiveness between male and female semi-professional football players. The OLMT objectively assessed three constructs regarding achievement motivation: motivation through personal goals, aspiration level, and motivation through competition. In addition, competitiveness was measured with the self-reported Competitiveness-10 Questionnaire. Finally, participants’ performance was assessed by three expert observers in each of ten matches. Thirty-eight football players (men = 27; women = 11) participated in the present study, and no significant differences were found in the Levene test when comparing men and women with respect to the scores obtained in the different measures used in our research. Significant differences were found in the motivation through competition (p = 0.021) as well as in self-reported competitiveness (p = 0.020) as a function of gender, with males showing higher values in both cases. No gender differences were found in aspiration level (p = 0.283) or motivation through personal goals (p = 0.897). Moreover, age and player performance did not modulate gender differences on any measures. No significant correlation was found between motivational measures and performance. In conclusion, it should be noted that the only variable on which gender differences emerged was the level of competitiveness, such that males scored higher than females on both objective and self-reported measures.

Blood‐circulating EV‐miRNAs, serum TARC, and quantitative FDG‐PET features in classical Hodgkin lymphoma

Blood‐based biomarkers are gaining interest for response evaluation in classical Hodgkin lymphoma (cHL). However, it is unknown how blood‐based biomarkers relate to quantitative 18F‐FDG‐PET features. We correlated extracellular vesicle‐associated miRNAs (EV‐miRNA), serum TARC, and complete blood count (CBC) with PET features (e.g., metabolic tumor volume [MTV], dissemination and intensity features) in 30 cHL patients at baseline. EV‐miR127‐3p, EV‐miR24‐3p, sTARC, and several CBC parameters showed weak to strong correlations with MTV and dissemination features, but not with intensity features. Two other EV‐miRNAs only showed weak correlations with PET features. Therefore, blood‐based biomarkers may be complementary to PET features, which warrants further exploration of combining these biomarkers in prognostic models.

Abstrak laun ditentukan oleh wearables Global Positioning System (GPS) dan pedometer. wearables GPS tidak berfungsi dengan baik apabila digunakan kondisi indoor, Sementara pedometer pengukuran jumlah langkah tidak dapat menghitung jarak secara spesifik dikarenakan langkah kaki yang tidak konsisten. Penelitian ini bertujuan untuk merancang alat yang dapat mengukur jarak tempuh dari kegiatan lari laun menggunakan sensor Inertial Measurement Unit (IMU) dengan output percepatan linear, kemudian meredam noise pengukuran dengan menggunakan Kalman Filter . Sinyal percepatan diproses menjadi sinyal kecepatan dan sinyal kecepatan diproses menjadi sinyal jarak melalui pengintegralan. Dari hasil rancangan prototipe tersebut mampu mengukur jarak 25 m dengan error 0,78%, Abstract —Jogging is a form of trotting or running at a slow or leisurely pace. So far, the measurement of running distance is determined by wearables Global Positioning System (GPS) and pedometers. The use of wearables with GPS commonly used by joggers cannot be used in indoor conditions. In addition, the use of a pedometer for measuring the number of steps cannot calculate the specific distance due to the inconsistency of human footsteps. This study aims to design a device to measure the distance traveled in jogging. To measure the distance traveled in a run, an Inertial Measurement Unit (IMU) sensor can be used with a linear acceleration output then reduce the measurement noise by using a Kalman Filter. The acceleration signal is processed into a velocity signal and the velocity signal is processed into a distance signal through integration. From the results of the prototype design, it is able to measure a distance of 25m with an error of 0.78%, a distance of 50m with 0.53% and a distance of 75m with 0.22%.
