Dynamic Amplification of Railway Bridges under Varying Wagon Pass Frequencies
Authors: Rahman Aminur K. , Imam Boulent , Hajializadeh Donya
Published: March 2024

Train configurations give rise to a primary wagon pass forcing frequency and their multiples. When any one of these frequencies coincides with the natural frequency of vibration of the bridge, a resonant response can occur. This condition can amplify the dynamic response of the bridge, leading to increased levels of displacement, stresses and acceleration. Increased stress levels on critical bridge structural elements increases the rate at which fatigue damage accumulates. Increased bridge acceleration levels can affect passenger comfort, noise levels, and can also compromise train safety. For older bridges the effects of fatigue, and being able to predict the remaining life, has become a primary concern for bridge engineers. Better understanding of the sensitivity of fatigue damage to the characteristics of the passing train will lead to more accurate remaining life predictions and can also help to identify optimal train speeds for a given train–bridge configuration. In this paper, a mathematical model which enables the dynamic response of railway bridges to be assessed for different train configurations is presented. The model is based on the well established closed from solution of the Euler–Bernoulli Beam (EBB) model, for a series of moving loads, using the inverse Laplace–Carson transform. In this work the methodology is adapted to allow different train configurations to be easily implemented into the formulation in a generalised form. A generalised equation, which captures the primary wagon pass frequency for any train configuration, is developed and verified by presenting the results of the bridge response in the frequency domain. The model, and the accuracy of the equation for predicting the primary wagon pass frequency, is verified using independently obtained measured field train–bridge response data. The main emphasis of this work is to enable the practicing engineer, railway operators and bridge asset owners, to easily and efficiently make an initial assessment of dynamic amplification, and the optimal train speeds, for a given bridge and train configuration. This is visually presented in this work using a Campbell diagram, which shows dynamic amplification and compares this with those calculated based on the design code, across a range of train speeds. The diagram is able to identify train speeds at which a resonance response can occur, and the wagon pass frequency, or its multiples, which are causing the increased dynamic amplification. The model is implemented in Matlab and demonstrated by analysing a range of short- to medium-single span simply supported plate girder railway bridges, typically found on the UK railway network, using the standard BS-5400 train configurations. The model does not consider the effects of the train mass and suspension system as this would require a non-closed form numerical solution of the problem which is not practical for the purposes of an initial assessment of the train–bridge interaction problem.
Inferior Vena Cava Filters: A Clinical Review and Future Perspectives

Published: March 2024

Anticoagulation represents the first line treatment for venous thromboembolism (VTE). However, inferior vena cava (IVC) filter insertion can be considered as a possible therapeutic strategy when anticoagulant therapy is contraindicated, to avoid embolization from the lower limbs to pulmonary circulation. Other possible indications are debated among experts. Both permanent and retrievable caval filters are available in clinical practice. Retrievable filters can be removed when no longer necessary, as their use may be indicated only for a limited amount of time. Moreover, caval filter insertion is not devoid of possible complications, particularly in cases of permanent or long-dwelling filters. A multidisciplinary approach is recommended to review the appropriateness of caval filter use and to define the best timing for retrieval.
Development of a Polyethylene Glycol/Polymethyl Methacrylate-Based Binder System for a Borosilicate Glass Filler Suitable for Injection Molding
Authors: Zürn Martin , Schrage Annika , Antusch Steffen , Bohn Nicole , Holzer Peter , Hanemann Thomas
Published: March 2024

Powder injection molding is an established, cost effective and often near-net-shape mass production process for metal or ceramic parts with complex geometries. This paper deals with the extension of the powder injection molding process chain towards the usage of a commercially available borosilicate glass and the realization of glass compounds with huge densities. The whole process chain consists of the individual steps of compounding, molding, debinding, and sintering. The first part, namely, the search for a suitable feedstock composition with a very high solid load and reliable molding properties, is mandatory for the successful manufacture of a dense glass part. The most prominent feature is the binder composition and the related comprehensive rheological characterization. In this work, a binder system consisting of polyethylene glycol and polymethylmethacrylate with stearic acid as a surfactant was selected and its suitability for glass injection molding was evaluated. The influence of all feedstock components on processing and of the process steps on the final sintered part was investigated for sintered glass parts with densities around 99% of the theoretical value.

Published: March 2024

In this work, two types of 590 MPa grade steels, composed of NiCrMo steel and Cu-bearing steel, were processed using traditional offline quenching and tempering and direct quenching (DQ) and tempering. The influence of DQ on microstructural evolution and strengthening mechanisms of these two types of steel was investigated. Grain refinement and dislocation density increase were determined by controlled rolling and following the DQ process in both two types of steel. In Cu-bearing steels, the refined grains and high-density dislocation further promoted the precipitation behavior of Cu-rich particles and alloyed carbides during the tempering treatment. Compared with traditionally quenched and tempered steels, NiCrMo steels after the direct quenching and tempering (DQT) process achieved 106 MPa higher yield strength through grain refinement strengthening and dislocation strengthening, while the Cu-bearing steels after the DQT process achieved 159 MPa higher yield strength through grain refinement strengthening, dislocation strengthening, and precipitation strengthening. The contribution degree of different strengthening mechanisms was quantitatively analyzed. Grain refinement also compensated for the toughness loss caused by the increase in dislocation, leading to an impact energy of 237 J and 248 J at −84 °C for NiCrMo and Cu-bearing steels after DQT, respectively.

Published: March 2024

With the development of the mobile network communication industry, 5G has been widely used in the consumer market, and the application of 5G technology for indoor positioning has emerged. Like most indoor positioning techniques, the propagation of 5G signals in indoor spaces is affected by noise, multipath propagation interference, installation errors, and other factors, leading to errors in 5G indoor positioning. This paper aims to address these issues by first constructing a 5G indoor positioning dataset and analyzing the characteristics of 5G positioning errors. Subsequently, we propose a 5G Positioning Error Correction Neural Network (5G-PECNN) based on neural networks. This network employs a multi-level fusion network structure designed to adapt to the error characteristics of 5G through adaptive gradient descent. Experimental validation demonstrates that the algorithm proposed in this paper achieves superior error correction within the error region, significantly outperforming traditional neural networks.

Масштабна ліквідація шкіл на сільських територіях України в останні роки
переважно супроводжувалася спотвореним розумінням реформи децентралізації влади. В Україні, починаючи з 2014 року, здійснюється реформа децентралізації влади. Тому базовою метою реформи децентралізації влади стала така зміна моделі управління, яка сприятиме формуванню спроможності територіальних громад. У забезпеченні спроможності територіальних громад одним із пріоритетних засобів є здатність самостійно або через відповідні органи місцевого самоврядування забезпечувати належний рівень надання публічних послуг, зокрема у сфері освіти. Втім, саме у сфері освіти в останні роки спостерігається негативна тенденція – масштабна ліквідація шкіл на сільських територіях України.
У питанні ліквідації сільських шкіл сплетено клубок проблем: на локальному та загальнонаціональному рівнях. На локальному рівні органам влади територіальних громад, що появилися внаслідок реформи децентралізації влади, легше закрити сільські школи, ніж думати, де взяти кошти для їхнього фінансування. На загальнонаціональному рівні проблема ліквідації сільських шкіл пов’язана з тим, що недолуга формула державної освітньої субвенції, яка наразі існує – одна з причин неспроможності громад утримувати школи. Питання закриття шкіл є болючим для сільських громад України. Тому варто його ретельно обговорювати на громадських слуханнях. Успішний розвиток території можливий за наявності партнерських відносин між владою та громадою.

This study addresses the problem of plant diseases and the difficulty of detecting them, and it presents a unique technique for the automatic detection of tea leaf diseases by combining neural networks and optimization techniques. Our research uses a curated database of tea plant leaf photographs that includes healthy and diseased specimens. The neural network (CNN) is trained and fine-tuned using optimization algorithms. To increase disease identification accuracy, we used a hybrid novel optimization algorithm called (POA-MA) which is Pelican Optimization Algorithm (POA), and Mayfly Optimization Algorithm (MA) for feature selection, followed by classification with Support Vector Machine (SVM). The suggested mechanism performance is evaluated using accuracy, MSE, F-score, recall, and sensitivity measures. The suggested CNN-POAMA hybrid model yielded 94.5%, 0.035, 0.91, 0.93, and 0.92, respectively. This study advances precision agriculture by establishing a strong framework for automated detection, allowing for early intervention, and eventually enhancing tea crop health.
Exploring actinobacteria isolated from coral originated from Tulamben Bali in inhibiting multidrug resistance bacteria

Published: March 2024

Increasing bacterial resistance has reduced the effectiveness of most clinical antibiotics. The limited option of antibiotics to treat Multi-Drug Resistance pathogen infections indicates that there is an urgency to explore new antibiotic candidates. Coral is recognized to produce bioactive compounds that have the potential to develop new medicinal materials with antibacterial properties. The use of marine invertebrates for compound production will reduce populations in nature, therefore associated microbes are preferred due to their environmental friendliness. Actinobacteria is one of the coral-associated microbes capable of producing active compounds of secondary metabolites as antibacterials. This study aimed to identify coral and obtain isolates of Actinobacteria associated with coral potential as an antibacterial against MDR bacteria. This research uses an explorative method. The method used is coral identification based on the morphology and shape of the sclerite. Screening of antibacterial activity was carried out using the agar plug method, microscopic observation using Gram staining and molecular identification of potential isolates by PCR. The results showed that the coral genera obtained were Siphonogorgia sp., Menella sp., Echinomuricea sp., Dendronephthya sp., and Epizoanthus sp. The results of antibacterial activity indicated that 19 isolates inhibited the growth of MDR pathogen bacteria. However, only the potential isolates were identified. The microscopic observations showed isolate III.ISP2.10-2.3 and III.ISP2.10-2.6 have Gram-positive coccus and bacillus-shaped, respectively. Potential isolates III.ISP2.10-2.3 (Micrococcus yunnanensis) were found to have antibacterial activity against Acinetobacter baumanii, Pseudomonas aeruginosa, and Bacillus subtilis, while isolate III.ISP2.10-2.6 (Brevibacterium pigmentatum) had the greatest activity against B. subtilis.

Published: March 2024

Buah kurma adalah buah yang kaya vitamin, mineral dan serat yang banyak mengandung manfaat  bagi kesehatan. Saat ini buah kurma sangat digemari oleh masyarakat karena selain memiliki kandungan vitamin juga kita mendapatkan sunnah dalam mengkonsumsi buah kurma yang merupakan buah kesukaan Nabi Muhammad saw. Masyarakat Kota Pekanbaru belum banyak yang mengenal dan mengembangkan budi daya bibit kurma Thailan ini. Maka menjadi tantangan bagi pengusaha bibit kurma Thailand dalam memasarkannya agar masyarakat dapat lebih mengenal dan tertarik dalam membudidayakan buah kurma di Pekanbaru, untuk itu maka perlu adanya strategi pemasaran yang dilakukan oleh pengusaha bibit kurma Thailand kepada masyarakat. Tujuan penelitian ini untuk mengetahui strategi pemasaran bibit kurma Thailand dan untuk mengetahui faktor-faktor pendukung dan penghambat pemasaran bibit kurma Thailand di Kota Pekanbaru. Adapun yang menjadi sampel dalam penelitian ini adalah pengusaha bibit kurma Thailand sebanyak 10 responden. Dengan  menggunakan metode deskriptif melalui observasi dan wawancara yang dilakukan kemudian data dianalisa untuk diambil kesimpulan.

 

Hasil penelitian tentang strategi pemasaran yang dilakukan pengusaha bibit kurma Thailand di Kota Pekanbaru yang terdiri dari aspek produk, promosi, harga dan distribusi pemasaran menunjukkan bahwa strategi pemasaran bibit kurma Thailand yang dilakukan masih belum maksimal dikarenakan adanya keterbatasan dari pengusaha dalam mempromosikan produk dan kondisi ekonomi masyarakat yang masih belum stabil. Adapun faktor-faktor pendukungnya antara lain bibit kurma Thailand selalu tersedia, harga yang ditawarkan bervariasi dan belum banyaknya persaingan dalam usaha penjualan bibit kurma Thailand di Kota Pekanbaru. sedangkan faktor penghambat dari pemasaran bibit kurma Thailand ini adalah kurangnya promosi dalam memasarkan produk secara online dan minimnya pengetahuan masyarakat terhadap budidaya bibit kurma Thailand.

CIRI GANDA KOPERASI DAN PERMASALAHANNYA
Authors: Yewang Markus Umbu K
Published: March 2024

Koperasi merupakan salah satu pelaku ekonomi nasional yang memiliki karakteristik yang sama sekali berbeda dengan badan usaha lainnya, yaitu Badan Usaha Milik Negara (BUMN) dan Badan Usaha Milik Swasta (BUMS). Adapun karakteristik yang dimiliki koperasi dan tidak dimiliki oleh badan usaha lainnya, adalah bahwa koperasi memiliki ciri ganda, yaitu unsur ekonomi dan unsur sosial. Koperasi memiliki unsur ekonomi, yang artinya bahwa koperasi sebagai badan usaha harus melaksanakan berbagai kegiatan bisnis dan atau melaksanakan kegiatan bisnis tertentu dengan tujuan untuk mendapatkan keuntungan atau laba, dimana di dalam koperasi dikenal dengan nama Sisa Hasil Usaha (SHU). Pada akhirnya koperasi tersebut dapat dikembangkan usaha bisnisnya sekaligus dapat memenuhi berbagai kebutuhan para anggota secara khusus dan masyarakat pada umumnya. Unsur sosial dari koperasi adalah bahwa koperasi bukanlah kumpulan modal, melainkan kumpulan orang-orang yang mempunyai karakter kesukarelaan dan mau bekerja sama sebagai perwujudan dari asas gotong royong dan kekeluargaan. Permasalahan yang dihadapi koperasi di dalam mengimplementasikan cirri ganda tersebut adalah antara lain tidak adanya pembagian tugas yang jelas antara pengurus dengan pengelola koperasi, dalam hal ini badan pengurus koperasi dengan manajer koperasi. Tidak jelas siapa yang seharusnya melaksanakan unsur ekonomi dan siapa yang melaksanakan unsur sosial koperasi.

Excipients are used in drug delivery systems as a means of effectively delivering drugs to their target site. Multi-criteria decision-making (MCDM) methods are tools for decision-making that consider multidimensional factors. Such methods are a comparative technology used in medicine that combines individual criteria into the total assessment of selected alternatives. This study aims to enhance the solubility and bioavailability of drugs through the application of MCDM-based excipient selection. By incorporating the Preference Ranking Organization Method for Enrichment Evaluations (PROMETHEE), various excipients can be evaluated and ranked based on their suitability for specific applications, considering parameters related to drug solubility and bioavailability. The results highlight the potential of cyclodextrins (net flow: 0.0023) and Eudragit polymers (net flow: 0.0016) as preferred options for drug carriers, while Poloxamer 188 (P188) (net flow: -0.0030) is identified as the least preferred option. This study demonstrates the effectiveness of the PROMETHEE method in improving the performance of poorly soluble and bioavailable drugs, ultimately contributing to the development of new drug delivery systems. The findings have significant implications for therapeutic outcomes in the treatment of diseases.

IT IS BETTER TO BUY AT THE OFFICIAL STORE OR PREMIUM STORE AT E-COMMERCE
Authors: Johan Suwinto
Published: March 2024

E-commerce is a highly popular method of buying items right now. One of the many well-known e-commerce sites where many individuals are vying to create their own businesses is Tokopedia. Large corporations operate independently, but they also create their own official storefronts to entice customers to buy products directly from them without going through middlemen and benefiting from the Tokopedia guarantee. In order to draw clients and receive a guarantee from Tokopedia, retailers other than official stores and stores that are operated independently can upgrade to premium shops by paying a monthly charge. Potential customers take this into account because not all the things they desire are available in the official store. This study examines whether sales, establishment, operating hours, rating, and the number of couriers would affect consumers' decisions to make purchases from official stores and premium retailers.

Ambulatory blood pressure monitoring or ABPM is a non-invasive method to determine the average blood pressure for at least 24 hours, not only when medical checkup. ABPM is often found in cardiac examinations and monitoring of catlab preoperative patients. This study aims to analyze the performance of the ABPM tool that can measure blood pressure continuously with a specified time interval connected to IoT so that can make it easier to get test results. The contribution of this research is a 24-hour monitoring system with delivery via IoT. The experiment was conducted 10 times with Prosim comparison at each point to assess the level of reading accuracy and effectiveness of IoT viewers. At 120/80 mmHg systole accuracy 98.42%, diastole 97.25%. While at 150/100 mmHg systole accuracy is 99.67%, Diastole is 98.1%. At 200/160 mmHg point Systole accuracy 98.35%, Diastole 98.25%. The SPSS test states that the reading data collection is acceptable and has an average commensurate with the test. The difference in viewer time on the TFT and IoT layers is 3.8 seconds and the test data value is 0% loss. The results from making this module, concluding by utilizing the sensor MPX5050 obtained sufficient accuracy, the use of ESP32 as a microcontroller processes the sensor readings which will be converted into systole-diastole values and displays on IoT so that it can slightly help analyze the patient's condition, and this module can read the simulator tool well at pressures of 120/80 mmHg, 150/100 mmHg, and 200/160 mmHg. The device showed good accuracy and reliability in measuring blood pressure at different levels compared to a vital signs simulator. The device can be used for 24-hour monitoring of hypertension patients and provide useful information for diagnosis and treatment.
