Authors: Maryam Dewi , Pan Hsien‐Ting , Lin Wen‐Li , Harianto Susilo , Wu Li‐Min 
Published: March 2023

AbstractBackgroundCancer and its treatments cause significant stress in children and adolescents. This stress is associated with risks of emotional and behavioral problem development and interfering with adherence to treatment regimens. Instruments enabling the precise evaluation of the coping behaviors of pediatric patients with cancer in clinical practice are needed.AimsThe study aimed to identify existing self‐report measures of pediatric coping patterns and to evaluate their psychometric properties, to aid the selection of tools for application to pediatric patients with cancer.MethodsThis systematic review was conducted according to the PRISMA statement and registered in PROSPERO (CRD 42021279441). Nine international databases were searched from their inception to September 2021. Studies with the main goal of developing and psychometrically validating pediatric coping measures with populations aged <20 years, not specific to any disease or situation, and published in English, Mandarin, or Indonesian were included. The Consensus‐based Standards for the Selection of Health Measurement Instruments (COSMIN) checklist was applied.ResultsOf 2527 studies initially identified, 12 met the inclusion criteria. Five scales had positive internal consistency ratings and adequate reliability (α > .7). Construct validity ratings were positive for five scales (41.6%), intermediate for three (25%), and poor for three (25%). No information was available for one (8.3%) scale. The Coping Scale for Children and Youth (CSCY) and Pediatric Cancer Coping Scale (PCCS) had the largest numbers of positive ratings. Only the PCCS was developed for pediatric patients with cancer and showed acceptable reliability and validity.Linking Evidence to ActionThe findings of this review highlight the need to increase the validation of existing coping measures in clinical and research settings. Some instruments seem to be specific to adolescent's cancer coping assessment and knowledge of these validity and reliability of the instruments may improve the quality of clinical interventions.

Published: March 2023

The Cotinguiba Formation, of Cretaceous age, located in the Sergipe-Alagoas Basin, Brazilian Northeastern coast, comprises carbonate breccias and carbonate shales interlayered with fine to coarse clastic sediments (mudstones, marls), deposited in the maximum sea level episode during the Cenomanian-Coniacian transgressive event. Core sections were selected from the formation materials, from which 20 plugs were obtained, representing the main carbonate horizons present in Cotinguiba Formation. The selected samples were analyzed with petrophysical and physical methods (air porosimetry, mercury injection, and acoustic wave velocity) and mineralogical methods (optical microscopic analysis, x-ray diffraction (XRD) and scanning electron microscopy (SEM)). Results showed that the clay minerals’ content in the carbonates varies from 2% to 20%, with illites/micas and interstratified illite/smectite as the most abundant clay minerals, containing also traces of chlorite and kaolinite, and presence of palygorskite varying from trace to 8%. According to the percentages of calcite, dolomite, and siliciclastic + clay minerals obtained in the XRD analysis, the carbonates were lithologically identified as limestone, impure limestone, dolomitic limestone, impure dolomitic limestone, impure calcitic dolostone, and impure dolostone. The rocks have a good porosity, varying from 6% to 20% in the carbonates, predominantly related to microporosity. Clay minerals’ content influenced the grain density and acoustic properties, albeit not having the same role with porosity and permeability. SEM images, though, show that they have an important role in microporosity. Grain density variation related to phyllosilicate content was observed more significantly in impure limestones with a clay content higher than 8%, and a more pronounced decrease was observed in samples with palygorskite. Microporosity is the main factor for reducing Vp and Vs velocities in those carbonates, with values not exceeding 5341 m/s for Vp and 3026 m/s for Vs but, when clay content is higher than 4%, the Vp and Vs wave velocities do not exceed 4100 m/s and 2480 m/s, respectively. Therefore, the research allowed evaluating the influence of mineralogical and textural properties in the petrophysical properties of Cotinguiba Formation.

Published: March 2023

Mitigation of forest and land fires is very important to implement in peatlands. This paper aims to explain the role of Pertamina’s CSR communication in mitigating peatland fires around the company’s operational areas. This research used qualitative methods with case studies. The results showed that Pertamina’s CSR communication contributed to increasing awareness of fire disaster mitigation and changing people’s behavior in utilizing peatlands through the “Kampung Gambut Berdikari” program. In addition, the community was also trained and provided with fire extinguishers to prevent fires on peatlands. CSR implementers establish friendly relations and foster the Tunas Makmur farmer group and the Fire Concern Community (Masyarakat Peduli Api/MPA) group to prevent fires. CSR communication is able to increase the awareness of the surrounding community in managing the peat environment. CSR together with the community develops peat arboretum ecotourism and pineapple plantations for environmental education and improving people’s welfare. This peat arboretum ecotourism is not only a medium of communication to spread educational messages to the farmer community, but also to school students, youth and visitors. In the future, CSR program actors can implement environmental communication as a form of disaster mitigation to prevent forest and peatland fires.

Published: March 2023

Abstract
Intelligence is the trend of industrial development in today’s world, which will inevitably affect the nuclear power field, thus promoting nuclear power industry from digital to intelligent forward. 5G and Wi-Fi6, as a new generation of wireless communication technologies, have important advantages in terms of technical performance and security due to the characteristics of dense personnel, wide equipment distribution, complex facility environment, and special materials used in nuclear power scenarios. Considering the high requirement of electromagnetic compatibility (EMC) in nuclear power environment, it is urgent to further study the electromagnetic interference and protection requirements of 5G, Wi-Fi6, and other new technologies on nuclear power unit equipment in nuclear power environment. In this paper, combined with relevant national document standards and industry standards, we will sort out the requirements of immunity about radiofrequency radiation (RFR) for the important equipment in nuclear power plants, and use signal generators to simulate new radio signals such as 5G and Wi-Fi6 to test the immunity of nuclear power instruments and meters. Combining the results of the test, we will study the EMC between new wireless technologies and nuclear power plant equipment from different factors, such as power, bandwidth, modulation, distance, and direction. And then, we will summarize the protection requirements about nuclear power equipment and propose interference protection measures.

Published: March 2023

AbstractIngestible devices have become a popular means for diagnosing and treating the gastrointestinal (GI) tract due to their noninvasive nature. However, their residency period in the GI tract is limited by the transit time through it. In previous work, we designed a tissue attachment mechanism (TAM) inspired by parasitic worms' attachment methods, which were tested for implanting biosensors or drug delivery payloads to the small intestine with a swallowable capsule robot. In that work, the attachment success rate was 91.7%, and the average attachment duration of the TAM was 32.2 h after factorial optimization of major design factors. This work develops a novel nitinol TAM (NTAM) for improving the attachment duration using the shape-changing properties of nitinol. The attachment strength of the NTAM to the intestinal tissue was assessed both ex vivo and in vivo. The attachment duration of the NTAMs in live porcine models was evaluated from radiographic images, and histological analysis of the attachment location of an NTAM was performed after euthanasia. The NTAM was 100% successful in an attachment strength study and achieved a maximum attachment duration of 13 days, while the average attachment duration was 85.63 ± 77.83 h. Histological analysis did not report any permanent damage to the tissue. This work shows a 2.7-fold improvement in attachment duration over the previous design. This work has demonstrated a method of prolonged attachment to the intestinal wall through a swallowable device, which can be used for long-term drug delivery or biosensing.
Swirl Effects On Gas-Liquid Upward Vertical Pipe Flow
Authors: Garcia Matheus M. , Portela Luis M. 
Published: March 2023

Abstract
When swirl is added to gas-liquid upward vertical pipe flows (e.g. inside an inline swirl separator), the classical flow patterns are modified by the centrifugal forces which act pushing the gas towards the center of the pipe and the liquid towards the wall. If the swirl is strong enough, this leads to the formation of a gas column in the center of the pipe, which can be either stable or intermittent. It was observed experimentally that the behavior of the gas column is strongly dependent on the dynamics of the gas-liquid flow upstream of the addition of swirl. In this video, a high speed camera was used to record the gas-liquid flow upstream and downstream of a swirl-generating element for different flow rates of liquid and gas, covering multiple non-swirling (upstream) and swirling flow patterns (downstream). The video: (i) shows the different swirling gas-liquid flow patterns and their dynamic behavior; (ii) analyzes the connection between the dynamics of the swirl patterns and the gas-liquid patterns upstream of the swirl element, via synchronized recordings of the two locations.
Critical Evaluation of a Novel Analysis Technique for Assessment of Printed Circuit Heat Exchangers in High-Temperature Nuclear Service
Authors: Shaw Avinash , Mahajan Heramb P. , Hassan Tasnim 
Published: March 2023

AbstractApplication of printed circuit heat exchangers (PCHEs) to very high-temperature reactors (VHTRs) requires mechanical performance assessment methodologies. The PCHE morphology consists of thousands of millimeter-scale channels, for enhanced thermal efficiency, enclosed in a meter-scale PCHE core. PCHE geometry under thermomechanical creep-fatigue transients results in multi-axial interactions between its different segments, such as channeled core, walls, and headers. These global-level interactions influence the local channel-level responses. Hence, developing a PCHE performance assessment methodology, following the ASME Code, Section III, Division 5 provisions, is a critical gap to be filled. There is no analysis or design methodology available in ASME Code to assess a PCHE for its global and local level performances under high temperature and pressure loadings. This paper critically evaluates a recently proposed two-step analysis technique to estimate global interactions and local channel-level responses of PCHEs. In this novel analysis technique, the channeled PCHE core is replaced with orthotropic solid blocks of representative stiffness properties for the global thermomechanical analysis. Subsequent channel scale submodel analysis with detailed channel geometry, loading, and elastic-perfectly plastic (EPP) material model estimates the local responses for PCHE performance assessment. This paper critically evaluates this novel technique for its effectiveness in PCHE performance assessment. Finite element (FE) models imitating various analysis issues are developed, and FE analysis results are scrutinized. An important outcome of this study is the validation of the novel two-step PCHE analysis technique for application to the performance assessment of PCHEs in VHTRs.
A Vibrating-String Model for Closed-Loop Wave Transmission and Reflection Between the Aorta and Periphery
Authors: Hao Zhili 
Published: March 2023

Abstract
A tube-load model is used to reconstruct aortic pressure waveform from peripheral pressure waveform. Yet, the reconstructed aortic pressure waveform is greatly affected by load impedance used. In this work, a vibrating-string model for closed-loop wave transmission and reflection between the aorta and periphery is developed to examine the roles of all the parameters involved in aortic pressure waveform. The arterial pulsatile wave theory gives rise to the standard one-dimensional wave equation for a vibrating string. A vibrating-string model based on radial displacement of the arterial wall is developed to relate aortic pressure waveform to peripheral pressure waveform, relate load impedance to input impedance, and derive theoretical expressions for associated clinical indices. The vibrating-string model is extended to incorporate blood velocity and is further connected to the left ventricle (LV) to study the role of the LV in aortic pressure waveform. The difference between the vibrating-string model and the tube-load model is also examined. Load impedance is identified as an indispensable independent parameter for reconstruction of aortic pressure waveform with accuracy, and its physiologically realistic harmonic dependence can only be obtained from the measured input impedance. The derived expressions for clinical indices interpret some clinical findings and underscore the role of harmonics in clinical indices. Some misconceptions in the tube-load model are revealed, including load impedance and characteristic impedance. This work clarifies the role of harmonics-dependence of load impedance and harmonics of aortic pressure waveform in determining clinical indices.

Published: March 2023

AbstractThe air-assisted atomizer used in a two-stroke aviation engine has two separate operation sequences, namely the fuel injection and air injection, in contrast to the synchronous fuel/air injection of conventional effervescent atomizers for continuous combustion engines. This work presents a numerical flow modeling to explore the effects of these two injection sequences on the effervescent spray formation, using the combined methodology of Eulerian–Eulerian multiphase technique and Shear-Stress Transport k–ω turbulence model. The transient fuel delivery in the internal fuel passage of the atomizer and the effects of the injection sequences on the developments of the droplet sprays were studied. Three characteristic times T1, T2, and T3 were introduced to specify the fuel injection duration, air injection duration, and the time interval between these two injection sequences, respectively. The results showed that the most important role of T1 is to meter fuel mass loading, and T2 plays the dominant role in anchor-shaped spray structure. For the air-injection sequence, there is a critical time, T3c, which is defined as the minimum opening time of the air injector, for the complete ejection of the fuel in the atomizer, which shows a linear correlation to T2, but is weakly related to T1.

Published: March 2023

Abstract
The present study proposes a Quonset-type greenhouse integrated with a thin-film photovoltaic thermal (GiPVT) system combined with an earth-air heat exchanger (EAHE) for crop cultivation in harsh hot climate conditions. A periodic thermal model in terms of input climatic and design parameters has been developed to evaluate the GiPVT system’s thermal performance. This model is based on the energy balance equations of the GiPVT system, and it calculates PV roof temperature, greenhouse air temperature, and plant temperature for a given climatic data, i.e., solar irradiation and ambient air temperature. Furthermore, the thermal load leveling for the GiPVT system is determined to assess the thermal comfort status within the enclosed space of the system. The results indicate that EAHE successfully reduces greenhouse air temperature and increases the thermal comfort level inside the GiPVT system. Corresponding to the optimum flowrate of 0.5 kg/s, the maximum temperature of the plants and greenhouse is reduced by 20 °C and 21 °C, respectively. Moreover, the present GiPVT system produces 29.22 kWh of electrical energy per day, making the system self-sustainable.
Habitually Scrolling: An Examination Into How Sport Consumers Use Social Media
Authors: Kennedy Heather , Funk Daniel C. 
Published: March 2023

Uses and gratifications theory has often been used in (sport) communication studies to examine social media usage. Yet, criticisms of uses and gratifications theory (e.g., it overstates purposefulness) and competing research suggesting media use is more habitual and unconscious in nature have often been overlooked. Thus, through semistructured interviews, this research explored how social media is used, identifying five themes: passively, distinctly, periodically, habitually, and universally. Theoretically, this research contributes by highlighting the passive, habitual, and unconscious nature of some sport social media behavior, thereby challenging our current assumptions that sport social media usage is always active, purposeful, and goal directed. It also considers the uniqueness (or lack thereof) of sport content within the social media experience. Managerially, this research helps sport organizations understand how consumers use social media to inform marketing and communication strategies.

Published: March 2023

Patients with knee osteoarthritis and varus knee deformity have impaired postural balance, resulting in decreased walking performance and an increased risk of falls. This study aimed to investigate the early changes in the postural balance following inverted V-shaped high tibial osteotomy (HTO). Fifteen patients with medial knee osteoarthritis were recruited. Postural balance was assessed using the center-of-pressure (COP) data during single-leg standing before and 6 weeks after inverted V-shaped HTO. The maximum range, mean velocity, and area of COP movements in the anteroposterior and mediolateral directions were analyzed. Preoperative and postoperative visual analog scale for knee pain was assessed. The maximum range of COP in the mediolateral direction decreased (P = .017), whereas the mean velocity of COP in the anteroposterior direction increased 6 weeks postoperatively (P = .011). The visual analog scale score for knee pain significantly improved at 6 weeks postoperatively (P = .006). Valgus correction with inverted V-shaped HTO resulted in improved postural balance in the mediolateral direction and good short-term clinical outcomes early following surgery. Early rehabilitation after inverted V-shaped HTO should focus on postural balance in the anteroposterior direction.
Complex motion of Greenland Ice Sheet outlet glaciers with basal temperate ice

Published: March 2023

Uncertainty associated with ice sheet motion plagues sea level rise predictions. Much of this uncertainty arises from imperfect representations of physical processes including basal slip and internal ice deformation, with ice sheet models largely incapable of reproducing borehole-based observations. Here, we model isolated three-dimensional domains from fast-moving (Sermeq Kujalleq/Store Glacier) and slow-moving (Isunnguata Sermia) ice sheet settings in Greenland. By incorporating realistic geostatistically simulated topography, we show that a spatially highly variable layer of temperate ice (much softer ice at the pressure-melting point) forms naturally in both settings, alongside ice motion patterns which diverge substantially from those obtained using smoothly varying BedMachine topography. Temperate ice is vertically extensive (>100 meters) in deep troughs but thins notably (<5 meters) over bedrock highs, with basal slip rates reaching >90 or <5% of surface velocity dependent on topography and temperate layer thickness. Developing parameterizations of the net effect of this complex motion can improve the realism of predictive ice sheet models.
