Abstract
Information and Communication Technology is playing a vital role in virtually almost every field of human operation such as education sector, medical field, banking sector, agricultural sector, field of engineering and more. Information and Communication Technology has substantially eased operations in several fields and has helped to save resources in the likes of labor, cost and time. It has also helped to drastically increase the speed at which work is done. This paper reviews the impact of information and communication technology in civil engineering practice and examines operations such as the construction industry, road transportation industry, engineering education, structural engineering, energy efficient buildings, building preservation and engineering design. Information and Communication Technology is seen to be very relevant for sustainability in civil engineering practices across literature.
Hazard Assessment and Implementation Strategies for Mitigating of Flood and Erosion in Nigeria
Authors: Oyebode O J 
Published: March 2021

AbstractThere are notching unresolved issues and environmental hazards traceable to flood and erosion in major rural areas and notable communities in Nigeria. Researchers’ efforts on erosion control and flood mitigation have not yielded notable fruits due to inadequate planning and implementation strategies. Maintenance of roads and other infrastructures are the bed rock of any development round the globe. This paper assessed recent occurrence of flood and erosion. The study examined the causes, urban and regional planning of the affected area, construction practices, damages and maintenance practices. Questionnaires, field study and interview of experts were wont to elicit information from people within the affected location, officials from state and native government agencies charged with rehabilitation of affected areas. The research finding revealed that there are inadequate drainage systems, lack of enforcement of plan, corruptions, failure of systems, poor supervision, construction malpractices, lackadaisical attitude and lack of maintenance culture. Implementation strategies were highlighted to avert flood and erosion ravaging several areas of the country. The paper concluded that stakeholders, researchers, engineers should partner with government agencies within the planning, construction, management and maintenance of rural and concrete drainages for adequate funding and sustainable construction. It is recommended that strategies for alleviating flood and erosion should be implemented supported latest technology for sustainable infrastructural development. Periodic hazard assessment should be planned in various geopolitical zones especially Lagos, Niger delta and rain forest region of Nigeria. Land use control, landscape maintenance, weather stations, proper enforcement of construction works consistent with plan should be strategically put in situ for effective monitoring and alleviation of flood and erosion in Nigeria.
Corrosion inhibition and statistical data of thiocarbanilide and thiocarbanilide admixed with 4-hydroxy-3-methoxybenzaldehyde on carbon steel in dilute acid media
Authors: Loto R T , Loto C A 
Published: March 2021

Abstract
The inhibition performance of thiocarbanilide (TD) and thiocarbanilide admixed with 4-hydroxy-3-methoxybenzaldehyde (TDHM) on the corrosion of mild steel in 1M H2SO4 and HCl acid solutions was studied through coupon measurement. Data obtained showed the optimal performance of TD is 71.69% in H2SO4 and 83.14% HCl acid solution respectively. TDHM performed more effectively with optimal inhibition efficiency of 96.77% and 97.21% in both acids. The result showed the performance of corrosion inhibiting compounds improves through synergistic interaction with other compounds. However, exposure time and inhibitor concentration strongly influenced the performance of the compounds at varying degrees. Statistical data shows the standard deviation for inhibition efficiency of the compounds was significantly higher in H2SO4 compared to HCl due to the high degree of variation analogous to exposure time and stability of the inhibitor molecules. TD and TDHM generally showed lower standard of deviation, higher mean value, lower margin of error and higher proportion of inhibition efficiency data above 70% inhibition performance. Statistical data from analysis of variance depict both exposure time and inhibitor concentration is statistically relevant, and influences the inhibition performance of TD and TDHM compounds. However, the influence of concentration is significantly limited compared to exposure time with statistical relevance values above 60%

Published: March 2021

Abstract
This study correlated the thermal and mechanical properties of concrete produced with anacardium occidentale (cashew) nutshell ash (AONA). Cashew nutshells, agricultural waste products, was valorized to obtain AONA. AONA was replaced at 5, 10, 15, and 20 wt% of cement to produce concrete grade 25 MPa. Density, compressive strength, and thermal conductivity of the concrete samples were determined at 28 days curing, and the results were correlated using regression model analysis. The experimental findings revealed that the compressive strength increased with increasing AONA content. Moreover, both density and thermal conductivity reduced as AONA content increased. Besides, the correlation yielded a high precision with 97% “R2”. Thus, AONA has proved to exhibit higher mechanical strength with excellent thermal insulation when utilized as supplementary cementitious material (SCM) in concrete production. The developed model can also be applied to the correlation of thermomechanical properties of concrete incorporating SCMs in that time, energy, and cost in conducting laboratory works would be reduced.

Published: March 2021

Abstract
Atmosphere pressure chemical vapor deposition (CVD) is one of the most powerful methods of synthesizing high quality and large area MoS2 films with a reasonable cost. In our work, the large-scale and high crystalline quality monolayer MoS2 nanosheets were synthesized on Silicon substrate with a 300 nm oxide layer using MoO3 and S powders as precursors by an atmosphere pressure CVD. The results suggest that the surface morphology, crystalline quality and luminescence of CVD-grown MoS2 nanosheets can be tunable by controlling the precursor ratio (the effective Mo: S ratio). Excessive S-rich atmosphere is favor to synthesize large-size and high crystalline quality monolayer MoS2 nanosheets with sharp corners and straight edges. This study may provide insight into the synthesis of large-scale and high crystalline quality MoS2 films.
Pore-level CFD investigation of velocity and pressure dispositions in microcellular structures
Authors: Otaru A J , Samuel M B 
Published: March 2021

AbstractPore-level computational modelling and simulation have recently become the focus of considerable attention in the field of transport in porous media. This study presents pore-structure characterisation and computational fluid dynamics (CFD) modelling and simulation of fluid flow distribution across ‘real’ and ‘structure-adapted’ porous metallic structures derived from tomography datasets at the microscale level. The resulting CFD predicted pressure drop data as a function of superficial fluid velocity ranging between 0 and 6.0 m.s−1were used to account for the viscous (permeability,k0) and inertial (Form drag coefficient,C) terms of the porous samples. CFD modelling confidence was established by validating with experimental measurements for foam samples available in the literature. Exprerimental values ofk0were found to be consistent with values available in the literature, while observable deviations of experimental measurements ofCfrom predicted values (in some cases) strongly support the reliability of the inertial terms in superficial fluid flow velocity, nature of fluid, and level of extended tortuous pathway in porous metallic structures. The adaptation of the ‘real’ structures through erosion and dilation of their skeletal phases enabled the creation of ‘semi-virtual’ structures; thereby providing an in-depth understanding of the manifestation of flowing fluid from Darcy to inertial and a graphical relationship linking pore-structure related parameters and fluid flow properties of the porous media was substantiated.
Investigations on microstructural characteristics and mechanical properties of 316 L stainless steel welded joints using nickel coated filler material by gas tungsten arc welding
Authors: D Aravindkumar , R Thirumalai 
Published: March 2021

Abstract
The main objective of this present study is to weld the 316 L stainless steel (SS) joints by gas tungsten arc welding (GTAW) process using nickel coated filler materials. The existing modified filler metals with flux coatings used in GTAW are generally accompanied with more complications. Therefore it is essential to suppress complications and enhance the welding strength which significantly depends on filler metals properties. In this work, the filler materials used in GTAW are coated with nickel in several grades for welding process. The results of these filler metals are compared with the Plain-316 filler metal. Ni-304 filler metal shows better uniformed weldment and heat affected zone (HAZ) with less planer slip micorstrucutre on its surface. The tensile test results reveal that Ni-316, Ni-304 & Ni-308 filler metals produces fracture on the parent metal. Among the various filler metals used, Ni-304 filler metal shows the highest impact toughness of 69.10 J and it is 71% higher toughness than Plain-316 filler. Average hardness of Ni-308 filler metal is 2.78% higher than the Plain-316 filler metal. Scanning electron microscope (SEM) images of weldments and HAZ were analysed to investigate the effect of nickel on the microstructure changes.
Metal substitution in the metalloporphyrin linker of metal−organic framework PCN-601 for photocatalytic CO2 reduction

Published: March 2021

Abstract
Metalloporphyrinic metal–organic framework PCN-601 exhibits high photocatalytic performance for CO2 reduction. The photoreduction site was speculated to be the Ni atoms in the nodes and thus the single Ni atoms in the porphyrin centers are not effectively utilized. In this study, we applied Kohn–Sham density functional theory to investigate the effect of metal (Fe, Co, or Cu) substitution in the Ni-porphyrin linker of PCN-601 on the photocatalytic CO2 reduction. Our results show that the photocatalytic properties of Ni-porphyrin-based PCN-601, including photoexcitation, visible-light absorption, vacuum-aligned energy level, and CO2 adsorption strength and configuration, can be further optimized by Fe substitution in the Ni-porphyrin linker. In addition, Co-porphyrin-based PCN-601 is also found to be a promising candidate for CO2 photoreduction though its visible-light absorption is relatively weak in comparison with its Fe- and Ni-based analogs.
Anomaly detection in gravitational waves data using convolutional autoencoders
Authors: Morawski Filip , Bejger Michał , Cuoco Elena , Petre Luigia 
Published: March 2021

Abstract
As of this moment, 50 gravitational wave (GW) detections have been announced, thanks to the observational efforts of the LIGO-Virgo collaboration, working with the Advanced LIGO and the Advanced Virgo interferometers. The detection of signals is complicated by the noise-dominated nature of the data. Conventional approaches in GW detection procedures require either precise knowledge of the GW waveform in the context of matched filtering searches or coincident analysis of data from multiple detectors. Furthermore, the analysis is prone to contamination by instrumental or environmental artifacts called glitches which either mimic astrophysical signals or reduce the overall quality of data. In this paper, we propose an alternative generic method of studying GW data based on detecting anomalies. The anomalies we study are transient signals, different from the slow non-stationary noise of the detector. The anomalies presented in the manuscript are mostly based on the GW emitted by the mergers of binary black hole systems. However, the presented study of anomalies is not limited only to GW alone, but also includes glitches occurring in the real LIGO/Virgo dataset available at the Gravitational Waves Open Science Center. To search for anomalies we employ deep learning algorithms, namely convolutional autoencoders, which are trained on both simulated and real detector data. We demonstrate the capabilities of our deep learning implementation in the reconstruction of injected signals. We study the influence of the GW strength, defined in terms of matched filter signal-to-noise ratio, on the detection of anomalies. Moreover, we present the application of our method for the localization in time of anomalies in the studied time-series data. We validate the results of anomaly searches on real data containing confirmed gravitational wave detections; we thus prove the generalization capabilities of our method, towards detecting GWs unknown to our deep learning models during training.

Published: March 2021

Abstract
This work reports on the correlation between structure, surface/interface morphology and mechanical properties of pulsed laser deposited (PLD) β-Ga2O3 films on transparent quartz substrates. By varying the deposition temperature in the range of 25 °C–700 °C, ∼200 nm thick Ga2O3 films with variable microstructure and amorphous-to-nanocrystalline nature were produced onto quartz substrates by PLD. The Ga2O3 films deposited at room temperature were amorphous; nanocrystalline Ga2O3 films were realized at 700 °C. The interface microstructure is characterized with a typical nano-columnar morphology while the surface exhibits the uniform granular morphology. Corroborating with structure and surface/interface morphology, and with increasing deposition temperature, tunable mechanical properties were seen in PLD Ga2O3 films. At 700 °C, for nanocrystalline Ga2O3 films, the dense grain packing reduces the elastic modulus Er while improving the hardness. The improved crystallinity at elevated temperatures coupled with nanocrystallinity, the β-phase stabilization is accounted for the observed enhancement in the mechanical properties of PLD Ga2O3 films. The structure-morphology-mechanical property correlation in nanocrystalline PLD β-Ga2O3 films deposited on quartz substrates is discussed in detail.
Can person-centred care for people living with dementia be delivered in the acute care setting?
Authors: Abbott Rebecca A , Cheeseman Debbie , Hemsley Anthony , Thompson Coon Jo 
Published: March 2021

Abstract
The need to improve care for people living with dementia in the hospital setting has long been recognised. Person-centred care has the potential to improve the experience of care for persons living with dementia and their carers, and has been shown to improve the experiences of hospital staff caring for the persons living with dementia, however it remains challenging to deliver in a time- and task-focussed acute care setting. This commentary suggests that to embed person-centred care across the hospital environment, cultural changes are needed at organisational and ward levels. In particular there needs to be: leadership that supports and advocates for workforce capacity to recognise and meet both psychological and physical needs of people living with dementia, promotion of physical environments that support familiarisation and social interactions, an inclusive approach to carers and the development of a culture of sharing knowledge and information across hierarchies and roles. An evidence-based set of pointers for service change are described which highlight institutional and environmental practices and processes that need to be addressed in order for person-centred care to become part of routine care.
Invited Commentary: Code Review—An Important Step Toward Reproducible Research
Authors: Platt Robert W 
Published: March 2021

Abstract
In this issue of the Journal, Vable et al. (Am J Epidemiol. 2021;190(10):2172–2177) discuss a systematic approach to code review as a way to improve reproducibility in epidemiologic research. Reproducibility needs to become a cornerstone of our work. In the present commentary, I discuss some of the implications of their proposal, other methods to reduce coding mistakes, and other methods to improve reproducibility in research in general. Finally, I discuss the fact that no one of these approaches is sufficient on its own; rather, these different steps need to become part of a culture that prioritizes reproducibility in research.
Evaluation of the timing of MRSA PCR nasal screening: How long can a negative assay be used to rule out MRSA-positive respiratory cultures?

Published: March 2021

AbstractPurposePrevious studies indicate that the polymerase chain reaction (PCR) nasal assay for methicillin-resistant Staphylococcus aureus (MRSA) has a consistently high (&gt;95%) negative predictive value (NPV) in ruling out MRSA pneumonia; however, optimal timing of PCR assay specimen and respiratory culture collection is unclear.MethodsA study including 736 patients from a community hospital system was conducted. Patients were included if they had undergone MRSA nasal screening with a PCR assay and had documented positive respiratory culture results.ResultsIn the full cohort, the MRSA PCR nasal screen assay was demonstrated to have an NPV of 94.9% (95% confidence interval [CI], 92.8%-96.5%) in ruling out MRSA-positive respiratory cultures. When evaluating the NPV by level of care (ie, where the MRSA PCR nasal assay sample was collected), no significant difference between values for samples collected in an intensive care unit vs medical/surgical units was identified (NPV [95%CI], 94.9% [92.7%-96.6%] vs 95.3% [88.4%-98.7%]). Additionally, NPV remained high with use of both invasive (NPV [95%CI], 96.8% [92.7%-99.0%]) and noninvasive (NPV [95%CI], 94.5% [91.7%-96.2%]) respiratory sampling methods. Finally, when evaluating the effect of time between MRSA PCR nasal screening and respiratory sample collection, we found high NPVs for all evaluated timeframes: within 24 hours, 93.8% (90.1%-96.4%); within 25 to 48 hours, 98.6% (92.7%-100.0%); within 49 hours to 7 days, 95.7% (91.4%-98.3%); within 8 to 14 days, 92.9% (85.1%-97.3%); and after more than 14 days, 95.5% (84.5%-99.4%).ConclusionWe report high NPVs for up to 2 weeks between specimen collections, which allows clinicians to use a negative MRSA PCR nasal screen assay to rule out MRSA pneumonia, potentially leading to decreased exposure to MRSA-active antibiotics.
Health Effects of Chronic Intermittent Hypoxia at a High Altitude among Chilean Miners: Rationale, Design, and Baseline Results of a Longitudinal Study

Published: March 2021

Abstract

Objectives
This study aims to assess the health effects on mining workers of exposure to chronic intermittent hypoxia (CIH) at high- and very high-altitude mining compared with similar work at lower altitudes in Chile, and it also aims to constitute the baseline of a 5-year follow-up study.

Methods
We designed a cross-sectional study to assess health conditions in 483 miners working at 2 levels of altitude exposure: 336 working at a very high or high altitude (HA; 247 above 3900–4400 m, and 89 at 3000–3900 m), and 147 below 2400 m. Subjects were randomly selected in two stages. First, a selection of mines from a census of mines in each altitude stratum was made. Secondly, workers with less than 2 years of employment at each of the selected mines were recruited. The main outcomes measured at the baseline were mountain sickness, sleep alterations, hypertension, body mass index, and neurocognitive functions.

Results
Prevalence of acute mountain sickness (AMS) was 28.4% in the very high-altitude stratum (P = 0.0001 compared with the low stratum), and 71.7% experienced sleep disturbance (P = 0.02). The adjusted odds ratio for AMS was 9.2 (95% confidence interval: 5.2–16.3) when compared with the very high- and low-altitude groups. Motor processing speed and spatial working memory score were lower for the high-altitude group. Hypertension was lower in the highest-altitude subjects, which may be attributed to preoccupational screening even though this was not statistically significant.

Conclusions
Despite longer periods of acclimatization to CIH, subjects continue to present AMS and sleep disturbance. Compromise of executive functions was detected, including working memory at HA. Further rigorous research is warranted to understand long-term health impacts of high-altitude mining, and to provide evidence-based policy recommendations.

Gene Tracer: a smart, interactive, voice-controlled Alexa skill For gene information retrieval and browsing, mutation annotation and network visualization
Authors: Lou Shaoke , Li Tianxiao , Liu Jason , Gerstein Mark 
Published: March 2021

Abstract

Motivation
Traditionally, an individual can only query and retrieve information from a genome browser by using accessories such as a mouse and keyboard. However, technology has changed the way that people interact with their screens. We hypothesized that we could leverage technological advances to use voice recognition as an interactive input to query and visualize genomic information.

Results
We developed an Amazon Alexa skill called Gene Tracer that allows users to use their voice to find disease-associated gene information, deleterious mutations and gene networks, while simultaneously enjoy a genome browser-like visualization experience on their screen. As the voice can be well recognized and understood, Gene Tracer provides users with more flexibility to acquire knowledge and is broadly applicable to other scenarios.
