Saluran transmisi merupakan penghubung antara pembangkit tenaga listrik dengan sistem distribusi. Saluran transmisi terdiri dari dua jenis yaitu SKTT (Saluran Kabel Tegangan Tinggi) dan SUTT (Saluran Udara Tegangan Tinggi). Pada penelitian ini dibahas mengenai saluran transmisi di Pulau Madura yang menggunakan jenis SUTT dengan tegangan kerja 150 kV. Gangguan di saluran udara tegangan tinggi pada umumnya adalah gangguan fasa ke tanah dan gangguan petir. Karena saluran transmisi cukup panjang, maka peralatan proteksi yang cocok digunakan adalah rele jarak. Prinsip kerja rele jarak yaitu pembagian antara tegangan yang ada pada titik rele dan arus yang terlihat oleh rele. Penelitian ini bertujuan untuk melakukan perhitungan nilai setting proteksi pada saluran transmisi di Pulau Madura, tepatnya di saluran transmisi yang bersinggungan dengan Gardu Induk 150 kV Guluk-Guluk. Hasil penelitian menunjukkan bahwa nilai setting rele jarak telah sesuai standar IEEE dan NPAG dari Alstom dengan nilai impedansi zona 1 dalam rentang 4,09 Ω-12,08 Ω, zona 2 dalam rentang 6,4 Ω-18,88 Ω, dan zona 3 dalam rentang 10,09 Ω-22,7 Ω. Ketika diberi gangguan dengan bantuan software DigSILENT juga rele mampu mengisolasi gangguan dengan waktu trip pada zona 1 adalah 0,0 detik, zona 2 adalah 0,4 detik, dan zona 3 adalah 1,2 detik, sehingga waktu trip telah sesuai dengan zonanya.

Untuk menunjang distribusi tenaga listrik yang baik, PT. PLN UP3 Purwokerto melakukan rekonfigurasi pada penyulang RWO05 dan RWO07 di GI Rawalo, dengan tujuan mengurangi pembebanan pada penyulang RWO05. Atas dasar tersebut maka nilai setting peralatan proteksi perlu dilakukan perhitungan ulang agar dapat tetap bekerja secara optimal untuk mengamankan jaringan dari adanya gangguan. Penelitian ini mempelajari tentang koordinasi peralatan proteksi dari relai arus lebih dan recloser pada penyulang RWO05 dan RWO07 baik pada kondisi setting existing maupun setelah dilakukan resetting pasca rekonfigurasi. Berdasarkan hasil analisis, arus hubung singkat maksimum 14395 A pada gangguan 3 fasa dan arus hubung singkat minimum 577 A pada gangguan 2 fasa tanah. Koordinasi proteksi setting existing menunjukkan, apabila terjadi gangguan 2 fasa di titik 75% dan 100% serta gangguan 3 fasa dan 2 fasa tanah di titik 100% penyulang RWO05, relai incoming tidak bekerja sebagai pengaman cadangan. Setelah dilakukan resetting, koordinasi bekerja dengan baik dari pengaman utama yaitu recloser dan relai outgoing kemudian relai incoming akan bekerja sebagai pengaman cadangan. Grading time peralatan proteksi setting existing dan resetting sudah sesuai dengan standar IEC 60255 yaitu 0,3-0,5 detik. Waktu kerja peralatan proteksi lebih cepat dari waktu untuk mencapai ketahanan maksimum dari konduktor.

Abstract
This article considers a coupled finite and boundary element method for an interface problem for the acoustic wave equation. Well-posedness, a priori and a posteriori error estimates are discussed for a symmetric space-time Galerkin discretization related to the energy. Numerical experiments in three dimensions illustrate the performance of the method in model problems.
On generalized derivations of semirings
Authors: Dadhwal Madhu , Devi Geeta 
Published: July 2022

Abstract
In this paper, the notion of generalized derivations is characterized. Also, the action of these derivations on ideals is investigated and as a consequence, some results involving commutator identities are proved. Further, we explore the commutativity of prime additively inverse semirings in which generalized derivations satisfy certain differential identities. An extension to Posner’s second theorem is also established in the framework of generalized derivations.

Locating the university lecture as a contemporary educational practice
Authors: Crook Charles 
Published: July 2022

Abstract
The university lecture has attracted much critical evaluation over a long period. Yet it remains resilient in the face of such scepticism. However, the project reported here finds that a sample of experienced lecturers fail to recognise the terms of this critique in their own practice. They uniformly describe contrary approaches. These are characterised in terms of three communication priorities: orchestration, enactment, and dialogue. An emphasis on the dialogic nature of exposition suggested an exploratory intervention in which students collaborated with a peer around a recorded lecture. Transcripts of these sessions indicate the way in which lectures can prompt a ‘conversational’ reaction within their audiences. The overall pattern of findings reported here helps to interpret the resilience of the live lecture. The success of online courses implies that lecturing co-presence is central to the resilience of lecturing in mainstream education. This is interpreted in relation to practitioners’ continued protection of three imperatives within live exposition: community, conviviality and conversation.

AbstractCold spray process (CSP) is a thermal spray technology in which coating (10–40 µm) is formed in the solid state by the impingement of power particles with supersonic velocity (200–1,200 m/s2) on coupon employing compressed gas jet, below the melting point of coating powder. It is commonly referred as cold gas dynamic spray, high velocity powder deposition, kinetic spray and kinetic energy metallisation process. Using CSP, various engineering materials (metals, polymers and ceramics) and its composites can be deposited. It is unique and promising approach for obtaining surface coating and offers various technological benefits over thermal spray as kinetic energy is employed for deposition rather than thermal energy. This offers great benefits in additive manufacturing (AM) to develop a component denser, low oxide coating free of tensile residual stresses, and undesired chemical reactions compared to conventional AM and coating techniques. Cold spray additive manufacturing (CSAM) is the powerful and emerging technique in the field of AM to develop engineering components with improved performance covering broad range of functionalities of surface, subsurface and interfaces. There are few flaws in this technique; however, extensive research work is going in CSAM and repairing of components to meet the real-time applications. The main objective of this review article is to summarise the history, effect of process parameters on surface coating, research and development in CSP along with its implementation in AM, component repairing and biomedical, antimicrobial and electrical applications. A discussion on future trends in CSAM is also provided at the end part of this article.
A Historical Review and Theoretical Mapping on Short Video Studies 2005–2021
Authors: Wei Tao , Wang Xiaohong 
Published: July 2022

Abstract
The popularity of TikTok has sparked short video studies in global academia. Whereas in China, the market for short video platforms is already matured, which has seen numerous research publications. However, an overall review of short video research is still absent. Using the methods of science mapping and thematic analysis, we summarized the research and review articles from Web of Science Core Collection and CNKI (CSSCI and CSCD) from the past two decades. The main findings are: 1) There are four main stages in the development of short video studies and each of them is tightly related to the market growth; 2) Four main perspectives (media, economic, cultural and discursive) of short video studies with 12 clusters of core issues have emerged, and the visibility that short videos bring to ordinary people is the fundamental viewpoint of many studies; 3) Currently, the short video studies are going broader and deeper, attracting scholars from different academic backgrounds, and multiple methods are applied in the studies; 4) The papers from WoS and CNKI share some similarities but show more differences in the research issues, subjects and methods. We pointed out the limitations of present studies and possibilities of future research.
Numerical study on flue gas–liquid flow with side-entering mixing
Authors: Fan Ruonan , Liu Jingting , Yang Xinzheng , Chen Songying , Luan Deyu , Lu Guanlong 
Published: July 2022

Abstract
In this article, the side-entry agitator commonly used in the wet desulfurization absorption tower of a 300 MW thermal power unit was taken as the research object, and the gas–liquid two-phase flow field in the stirring tank was numerically simulated by using the two-fluid model based on Euler–Euler method. The vertical and horizontal velocity field distribution and gas phase distribution in the stirring tank were studied. The results showed that the side-entry agitator formed a “fountain” circulating flow in the stirring tank. The high-speed region of the liquid flow was mainly concentrated near the mixing blade and the bottom banded region. The range of large changes in the fluid velocity was mainly concentrated from the bottom of the mixing tank to 2–3 m from the bottom. The distribution of the oxidizing air was concentrated in the middle of the stirring tank. The mixing effect of two phases in the stirred tank was good, and the oxidizing air was fully diffused. The numerical study in this article has reference significance for in-depth understanding of the flow field and mixing effect of the side-entry agitator.

Published: July 2022

Abstract

Objectives
The compounding and administration of hazardous drugs present a potential risk to healthcare worker and patient safety. This study sought to evaluate the HD surface contamination in multiple pharmacy and nursing areas that include standardized cleaning techniques and utilization of closed system transfer devices.

Methods
This study was conducted at six different areas in the pharmacy and nursing areas. Each area was assessed three times for five different HD’s surface contamination at an initial, 3 month, and 6 month follow up. Hazardous drug surface testing was performed for five most compounded HDs. A total of 90 individual samples were taken and analyzed during the study.

Results
A total of 30 samples were collected at three different timepoints for a total of 90 individual samples and analysis results. All 90 samples were negative (below the lower limit of detection; 0.01 ng/cm2), for their respective drug residue.

Conclusions
The method and design described in this evaluation may offer a way to determine if a facility’s current HD work practices and controls retain reduced HD surface contamination based upon published threshold values. Adoption and utilization of standardized work, including use of a closed system transfer device, and cleaning practices, described in this study, may present an option for facilities to retain reduced HD surface contamination, based upon previously determined threshold values.

AbstractThe ability of industrial X-ray computed tomography (CT) to scan an object with several internal and external features at once causes increasing adoption in dimensional metrology. In order to evaluate the quality of a measurement value, the task-specific measurement uncertainty has to be determined. Currently, VDI/VDE 2630 part 2.1 gives a guideline to determine the uncertainty of CT measurements experimentally by conducting repeated measurements. This is costly and time-consuming. Thus, the aim is to determine the task-specific measurement uncertainty numerically by simulations (e. g. according to the guide to expression of uncertainty in measurement (GUM) Supplement 1). To achieve that, a digital twin is necessary. This contribution presents a simple first approach how a digital twin can be built. In order to evaluate this approach, a study comparing measurements and simulations of different real CT systems was carried out by determining the differences between the measurement results of the digital twin and of the measurement results of the real-world CT systems. The results have shown a moderate agreement between real and simulated data. To improve on this aspect, a standardized method to characterize CT systems and methods to implement CT parameters into the simulation with sufficient accuracy will be developed.

Comparison between the response in air and in water of two ionization chambers exposed to low-energy X-rays
Authors: Moreno-Ramírez Adriana , Massilion Guerda 
Published: July 2022

This work investigated the effect of two different media in the response of two Farmer-type ionization chambers exposed to low-energy x-rays from 27 kV – 155 kV. The measurements were performed in air and in liquid water. Independent of the ionization chamber, at effective energies below 30 keV (80 kV), the charge collected in liquid water can be up to 84% less than that generated in air. The lower is the energy, the smaller is the response in water compared to air. This can be associated to the rapid attenuation of the low-energy photon fluence by the water depth. At effective energies greater than 30 keV, the response in water becomes larger than that in air, reaching a maximum of 27% and 35% at 65 keV (150 kV) for A19 and A12 chamber, respectively. The difference in response between the two media is consistently greater for ionization chamber A19 at energy above 25 keV.
