Authors: Ukorebi Asuquo Bassey , M. George Anthony , Akaerue Emmanuel , Chigoziem Akakuru Obinna
Published: March 2024

Integrated seismic refraction tomography (SRT) and electrical resistivity tomography (ERT) were used to study near-surface cavities with the aim of determining their geophysical properties. Five seismic refraction profiles around the study area were carried out using a 24-channel seismograph (ES-3000) while four ERT and ERT profiles were also conducted with IGIS resistivity meter and PLOTREFA software respectively. The data was processed using the RES2DINV software. Travel-time curves and velocity models were generated from the processed SRT data for each survey line, and 2-D inverted apparent resistivity models along the same lines were also generated for the purpose of comparison respectively. The results as obtained from the profiles showed SRT 1 (with a modelled velocity of 1,216 m/s in layer two at a depth of approximately 11 m - 20 m beneath the subsurface and an estimated cavity diameter of 11 m) and ERT 1 (with an apparent resistivity of approximately 826 Ωm and a depth of approximately 12.5 m – 16 m) indicates that the near-surface cavity outcrop links with a close-by mountainous structure in the EW direction. Profiles SRT 2 (with an approximately modeled velocity layer of 980 m/s in layer two at an approximate depth of 3.5 m – 7.0 m) and SRT 3 (with a modeled velocity layer of approx. 1,000 m/s in layer two at an approximate depth of 4.0 m – 7.0 m and 3.0 m – 9.0 m); ERT 2 (with an apparent resistivity of approximately 80 Ωm); and ERT 3 (with apparent resistivities of 116 Ωm and 182 Ωm at depths of approximately 3.5 m to 6.4 m and 4.0 m to 15.8 m) indicates that the surface cavity outcrop extends underneath the road network (Odukpani Central Section of Calabar-Ikom Highway) with a width of approximately 12 m. Profiles SRT 4 and SRT 5 (with an average velocity layer of 1,000 m/s in layer two at an approximate depth of 6.0 m – 13.2 m), and ERT 4 (with apparent resistivity ranging between 121 Ωm and 172 Ωm) at a depth of approximately 9.5 m to 20.0 m reveal that the near-surface cavity extends up to about 11 m across the highway and about 120 m away from the edge of the road. The above result will serve as reliable technical information to Transport and Building Construction Engineers on the presence of cavities along road networks and settlement areas in Odukpani Local Government Area. The recommendation is also made for the use of other geophysical techniques like Ground Penetration Radar (GPR) in conjunction with SRT and ERT to get higher-resolution imagery of the study area.

Published: March 2024

Objectives: Unilateral vocal fold palsy independently of etiology results in glottic insufficiency leading to unfavorable short or long-term impact on voice quality. Our aim was to evaluate the effect of injection laryngoplasty using Radiesse® Voice and thyroplasty type I on glottic closure, voice quality and aerodynamics by comparing preoperative, short- and long-term results. Materials and Methods: Data of 32 consent patients were reviewed between 2012 and 2023. All patients underwent either injection laryngoplasty (14 patients) or thyroplasty type I (18 patients) under local anesthesia. Maximum phonation time, glottic closure based on videolaryngostroboscopy, VHI-30 values and GRBAS scale were recorded prior, short-term (3 month) and long-term (12 months) after procedures for statistical comparison. Friedman test, Mann-Whitney test and Wilcoxon signed rank tests were used for statistical analysis. Results: In injection laryngoplasty group, we found significant improvement in maximum phonation time (p = 0.002), grade of hoarseness (p = 0.002) and breathiness (p = 0.000) when comparing results before and short-term after procedure. In thyroplasty type I group we saw significant improvement of maximum phonation time (p = 0.000), glottic insufficiency (p = 0.000), all three VHI-30 components (p = 0.000), as well as grade of hoarseness, breathiness (both p = 0.000) and roughness (p = 0.011) of GRBAS scale when comparing voice outcome before and short-term after procedure. There was no significant difference in voice outcome results neither between short and long-term results nor between the two groups in any parameter. Conclusion: These results demonstrate both short and long-term efficiency of injection laryngoplasty and thyroplasty type I in the improvement of voice quality and glottic closure.

Authors: Singh Arush , Patil Atul J. , Sharma Ramesh N. , Jarial Raj K.
Published: March 2024

Fostering green sustainable transportation in the Indian food supply chain with the adoption of electric trucks (ETs) is seemingly a promising alternative. However, before widescale adoption, a thorough cost-benefit analysis is essential for making an apt decision towards transitioning to ETs. Utilizing data of 13 ETs, a total cost of ownership (TCO) model has been developed that outlines the economic benefits of ETs by evaluating the impact of factors like energy consumption, charging strategy, annual driven distances, route optimization, etc. With acquisition costs of ETs constituting 50–55 % of TCO the study outlines that ETs have significantly lower energy costs of 6–12 % (50–58 % for IC-engine trucks) and maintenance costs of 6–8% (13–18 % for IC-engine trucks), thereby reducing the overall TCO. Subsequently, a fleet-level analysis of ET adoption in a food supply chain comprising of four heavy-duty trucks and 16 medium-duty trucks has been performed with emphasis on assessment of supply chain-specific parameters like battery-mass penalty, level of utilization, etc. Overall, this study provides insight for fleet managers, policymakers and industry leaders to promote sustainable through an extended use of ET in the present scenario for the food supply chain.
Assessing written production in L2 Mandarin Chinese: fluency and accuracy
Authors: Yang Li , Zhao Zenan
Published: March 2024

This study utilized T-unit and character-unit indices to assess learners’ written production and evaluate their writing development in second language (L2) Chinese. Through a cross-sectional design, three L2 Chinese learner groups at different instructional levels completed a timed letter-writing task within 30 min. Guided by prior research, respective T-unit and character-unit measures were selected to assess fluency and accuracy of the collected writing data. The results showed that fluency was overall positively related to learners’ instructional level, regardless of the indices (T-unit vs. character-unit). Hence, T-units per minute and characters per minute are considered both valid tools to assess fluency in L2 Chinese writing. However, only errors per character, among the accuracy measures, was found to decline linearly with the increasing level, thus suggested to be valid for tapping accuracy development in L2 Chinese writing. Based on the findings, implications regarding the assessment of L2 Chinese texts were discussed.
Closed-loop electron-beam-induced spectroscopy and nanofabrication around individual quantum emitters

Published: March 2024

Color centers in diamond play a central role in the development of quantum photonic technologies, and their importance is only expected to grow in the near future. For many quantum applications, high collection efficiency from individual emitters is required, but the refractive index mismatch between diamond and air limits the optimal collection efficiency with conventional diamond device geometries. While different out-coupling methods with near-unity efficiency exist, many have yet to be realized due to current limitations in nanofabrication methods, especially for mechanically hard materials like diamond. Here, we leverage electron-beam-induced etching to modify Sn-implanted diamond quantum microchiplets containing integrated waveguides with a width and thickness of 280 nm and 200 nm, respectively. This approach allows for simultaneous high-resolution imaging and modification of the host matrix with an open geometry and direct writing. When coupled with the cathodoluminescence signal generated from the electron–emitter interactions, we can monitor the enhancement of the quantum emitters in real-time with nanoscale spatial resolution. The operando cathodoluminescence measurement and fabrication around single photon emitters demonstrated here provide a new foundation for the potential control of emitter–cavity interactions in integrated quantum photonics.
Pulsed excitation of a quantum oscillator: A model accounting for damping
Authors: Astapenko Valeriy , Bergaliyev Timur , Sakhno Sergey
Published: March 2024

This article proposes a model that accounts for damping of a quantum oscillator (QO) during pulsed excitation. Our model is based on the Schwinger formula, which calculates oscillator’s excitation probability through the energy of an associated classical damped oscillator. We utilize this model to describe the influence of damping on temporal and spectral dependences of QO excitation, induced by electromagnetic pulses with exponential and double exponential envelopes. The oscillator excitation is analyzed in terms of transition probability between stationary states after pulse termination. Here, we present an analytical description of these dependences, along with numerical results. Specifically, we derive analytical expressions that depict the saturation effect during pulsed excitation, taking into account the damping of a QO. The evolution of the temporal dependence of the excitation probability with a change in the damping constant is numerically traced. We demonstrate that the number of maxima in this dependence is determined by the values of pulse parameters and the damping constant.

Published: March 2024

This study thoroughly reviews the recent design methods for ultra-high-performance concrete (UHPC) with agricultural waste. The goal is to identify UHPC composites that meets environmental sustainability requirements while fulfilling workability, durability, and mechanical properties. The capacity of typical review studies is limited in bridging the various literature aspects systematically. The article includes comparative analyses identifying these methods’ intrinsic connections and current trends. The analysis indicates that 71% of documents on incorporating agricultural waste into UHPC are in the “Engineering” and “Materials Science” disciplines, with 69% being journal articles, and 27% conference documents. Significant research keywords involve “Ultra-High-Performance Concrete,” “Cements,” “Sustainable Development,” and “Agricultural Wastes,” highlighting the extensive exploration of agricultural waste in UHPC. It has been discovered that agricultural waste can replace silica fume in UHPC, improving strength and durability by reducing pore volume and enhancing microstructure. Substituting 5–30% of cement with rice husk ash significantly boosts compressive strength, enhancing cement hydration, pore structure, and pozzolanic reaction, offering substantial environmental benefits and supporting the construction industry’s contribution to low-carbon sustainable development. This article provides guidance and recommendations for developing sustainable UHPC to meet diverse design specifications, promoting environmentally friendly construction practices.

Merrigan, JJ, Stone, JD, Kraemer, WJ, Friend, C, Lennon, K, Vatne, EA, and Hagen, JA. Analysis of sleep, nocturnal physiology, and physical demands of NCAA women’s ice hockey across a championship season. J Strength Cond Res 38(4): 694–703, 2024—The aims of this study were to evaluate the (a) relationships between daily physical demands and nighttime sleep, heart rate (HR), and heart rate variability (HRV); (b) weekly changes in physical demands and sleep; and (c) differences among positions and between training and competition during a competitive season in National Collegiate Athletic Association (NCAA) women's ice hockey. Twenty-five NCAA Division I women's ice hockey athletes wore a sensor at night to monitor sleep quantity or quality (e.g., time asleep and sleep efficiency) and physiology (e.g., HR and HRV). During training and competitions (31 regular season and 7 postseason), athletes wore performance monitoring systems to assess workload demands (e.g., training impulse and TRIMP). As internal workload (TRIMP, Time >80% of HRmax, Average HR) during training or competition increased, nocturnal HRV decreased, HR increased, and Sleep Duration, Sleep Score, and Readiness Score decreased that night. Across the season, athletes experienced lower HRV, but exhibited longer sleep durations. Training Distance, Duration, Time >80% HRmax, Average HR, and TRIMP decreased, whereas competition Total Distance, Duration, and TRIMP increased across weeks throughout the season. There were differences across positions and season blocks when evaluating these data at the mesocycle level. Athletes slept longer before competition compared with training, but physiological data did not differ. Competitions had greater physiological demands than training. We speculate that the increased focus on sleep hygiene, as evidenced by the increase in sleep over the season, may have served as a recovery aid to combat physiological stress of accumulated demands of competitions that increased over time into postseason tournaments.

Pilon, R, Matos-Santos, L, Matlez, MP, Rodrigues, G, Amorim, F, Lattari, E, Farinatti, P, and Monteiro, W. Effects of isocaloric resistance, aerobic, and concurrent exercise on excess postexercise oxygen consumption in older adults. J Strength Cond Res 38(4): 755–761, 2024—Excess postexercise oxygen consumption (EPOC) is a major determinant of exercise-related caloric expenditure and metabolic adaptations. Exercise modality may influence the EPOC, but this issue has not been investigated in older adults. This study compared the EPOC after isocaloric bouts of continuous aerobic exercise (AE), resistance exercise (RE), and concurrent exercise (CE) in older individuals. Ten subjects (5 men; 73 ± 6 years) had their cardiorespiratory data assessed during AE, RE, and CE and along 30-minute postexercise recovery. Total energy expenditure (EE) during exercise was similar (p > 0.05) in AE (126.0 ± 30.7 kcal), RE (123.9 ± 30.6 kcal), and CE (130.8 ± 32.6 kcal), with different times to achieve the targeted EE (RE: 61.4 ± 1.9 minutes > CE: 43.3 ± 5.6 minutes > AE: 26.6 ± 5.7 minutes; p < 0.001). Consistently, the relative intensity during exercise was superior (p < 0.05) in AE (74 ± 15% oxygen uptake reserve [VO2R]) vs. CE (43 ± 13% VO2R) vs. RE (24 ± 9% VO2R). Despite the isocaloric conditions, average EPOC and EE were approximately 45% greater (p < 0.001) in AE (8.0 ± 2.3 L; 40.1 ± 11.7 kcal) vs. RE (5.6 ± 1.2 L; 28.1 ± 5.8 kcal) and CE (5.4 ± 2.3 L; 26.9 ± 11.5 kcal). In conclusion, the EPOC was greater after isocaloric AE vs. RE and CE performed by older adults. Exercise intensity seemed to be a more important determinant of EPOC than volume reflected by EE during exercise bouts. Moderate-intensity continuous AE was more time-efficient than RE and CE to achieve a target EE. In older individuals, AE should be preferred over RE or CE when the purpose is to increase the daily caloric expenditure.

Lockie, RG, Orr, RM, Montes, F, and Dawes, JJ. Expanding research on firefighter trainee fitness, reasons for academy release, and the predictive capabilities of fitness tests. J Strength Cond Res 38(4): 724–733, 2024—Firefighter trainees need a level of fitness to be admitted to and complete a training academy. Fitness could indicate a trainee's likelihood of graduation, in addition to their reasons for release. This study determined fitness differences between firefighter trainees who graduated (GRAD) from academy or were released because of injury (RELI), performance test failures (RELP), or resignation (RELR), and whether fitness predicted graduation. Occupational physical ability test (OPAT) data for 686 trainees were analyzed, including: Illinois agility test; push-ups; pull-ups; leg tucks; maximal aerobic capacity (V̇O2max); backward overhead medicine ball throw; 10-repetition maximum deadlift; and farmer's carry. Raw and scaled (based on internal scoring) scores were recorded. Trainees were split into GRAD (n = 576), RELI (n = 33), RELP (n = 66), and RELR (n = 11) groups. A 1-way ANOVA with Bonferroni post hoc calculated between-group differences. Stepwise linear regression determined whether fitness predicted group inclusion. Receiver operating curves and area under the curve (AUC) derived test accuracy for predicting academy release. The GRAD group was superior (p ≤ 0.04) to the RELI group in all tests except push-ups, pull-ups, and farmer's carry; RELP group in all tests except the farmer's carry; and RELR group in V̇O2max, deadlift, and total OPAT score. Select fitness tests could predict inclusion in each group, although the explained variances were low (∼1–11%). Raw V̇O2max (AUC = 0.71) and total OPAT score (AUC = 0.74) had acceptable prediction accuracy. Fitness influenced academy graduation and reasons for release. Scaled scores could predict group inclusion in this department; V̇O2max and total OPAT score provided the most accurate predictors for release.
Experimental Investigation of Mechanical Properties and Failure Mechanisms in Jute-Polyester Composite Laminates under Off-Axis Tensile Loading
Authors: Mache Ashok , Deb Anindya
Published: March 2024

This study focuses on the experimental investigation of the mechanical properties and failure mechanisms of jute-polyester composite laminates under off-axis tensile loading. Various off-axis tests were conducted to analyze the effects of different fiber orientations (0°, 15°, 30°, 45°, 60°, 75°, and 90°) with respect to the load direction. The experimental results revealed a decrease in both off-axis strength and elastic moduli as the off-axis angle increased. Notably, the 45° off-axis tests exhibited the lowest tensile strength and modulus, indicating a more ductile behavior with the highest failure strain. The tensile stress-strain relationship exhibited a nonlinear behavior during off-axis tension loading. Failure analysis was performed using the Tsai-Wu criteria, considering various values of the interaction coefficient F12. The tensile strength and modulus predicted by the Tsai-Wu criteria demonstrated a good correlation with the experimental results. Consequently, the Tsai-Wu criterion proves effective for analyzing the failure properties of woven fabric composites under multiaxial stress conditions.

In recent decades, many members of the public have come to see processed food as a problem that needs to be solved by eating “real” food and reforming the food system. But for many food industry professionals, the problem is not processed food or the food system itself, but misperceptions and irrational fears caused by the public’s lack of scientific understanding. In her highly original book, Charlotte Biltekoff explores the role that science and scientific authority play in food industry responses to consumer concerns about what we eat and how it is made. As Biltekoff documents, industry efforts to correct public misperceptions through science-based education have consistently misunderstood the public’s concerns, which she argues are an expression of politics. This has entrenched “food scientism” in public discourse and seeded a form of antipolitics, with broad consequences. Real Food, Real Facts offers lessons that extend well beyond food choice and will appeal to readers interested in how everyday people come to accept or reject scientific authority in matters of personal health and well-being.
