Authors: Hayashi Chisato , Okano Tadashi , Toyoda Hiromitsu 
Published: March 2024

Abstract

Background: To prevent falls, individual worker factors and work environment factors should be considered.
Purpose: This study aimed to determine the risks of fracture from same level falls for occupational accidents in the transport industry, provide necessary interventions.
Methods: This study used the national open database of worker deaths and injury reports that was constructed from injury cases requiring four or more days of absence from work due to industrial accidents. We selected all same-level fall injuries from the original database using NVivo software.
Results: The average age of the population in the airline industry was 39.0 (standard deviation (SD; 11.6) years, and it was the youngest. In the hired taxi business, the average age of the population was 58.1 (SD; 9.1) years, which was the oldest in the transportation and traffic industry. The occurrence of fractures was 27.8% in hired taxi businesses, 23.0% in general cargo transportation, 21.9% in other road freight forwarding businesses, 18.3% in the railroad and track industry,16.5% in the bus line industry, and 7.5% in the airline industry. After adjusting for age, occurrence time, and number of employees, hired taxi businesses had 1.761 times greater risk of fracture (95% confidence interval [CI]: 1.049-2.956) compared to the railroad and track industry.
Conclusion: Taxi drivers were found to be at high risk of serious outcome such as fractures after same-level falls. The present study suggests that not only environmental interventions to prevent falls, but also lifestyle interventions to prevent fractures from occurring in the event of a fall might be needed.

Published: March 2024

Abstract

In this study, a molecular analysis, based on the comparison of mtDNA sequences of cytochrome oxidase I (COI) of the species Tanymastix stagnalis Linnaeus, 1758 from Algeria, with other available sequences, was performed. Phylogenetic analysis clarified the status of this species and its phylogenetic links between European and North African populations. This analysis clearly demonstrated that the only two populations from Algeria (Reghaïa and El Frine) are included within European sub-clad comprising northern Spain, France, northern Italy and Germany. We also provided ecological data over a decade of monitoring, which revealed that the population of T. stagnalis from El-Frine is stable and active during winter and spring. It lives in sandy pools and prefers low temperatures and conductivity (11.9 ± 2.2°C, 0.26 ± 0.15 mS.cm− 1, respectively). The mean density of its individuals was 1.43 ± 3.44 ind.L− 1, with a cyst-bank of 0.35 ± 0.14 egg.cm− 3. The cohabitation of T. stagnalis with the Decapoda Atyaephyra desmaresti (Millet 1831) in the El-Frine ponds is reported for the first time. Conservation measures should be undertaken to protect this endangered species in North Africa.
An Agent-based Exploration of Macroeconomic of Happiness: New Insights on Inequality and the Role of Reference Groups
Authors: Bruno Bruna 
Published: March 2024

Abstract

This study presents an agent-based model where individuals employ simple heuristics to assess their satisfaction for specific life satisfaction domains and for life satisfaction as a whole, considering reference groups of different dimensions. The objective is to evaluate whether different hypotheses on individual behaviors give different results at the macro level in the relationships between life satisfaction and some relevant variables, such as income. Results from simulations show that the relationship between life satisfaction and income has opposite signs when individuals perform their comparisons basing judgments on the mean or on the median income of their reference groups, and that the extension of the reference groups matters. A role for inequality emerges in determining the relationship between aggregate measures of income and life satisfaction. Results from simulations are validated through data from Eurobarometer for 24 European countries in the period 2008–2020, suggesting that people employ positional evaluations of satisfaction for the income domain by using the median income of the reference group as reference parameter.

Published: March 2024

Abstract
This paper investigates the effect of initial orbital elements on the orbital evolution of the Medium Earth Orbit (MEO) satellites of the third generation of the BEIDOU Navigation Satellite System (BDS-3), considering the lunisolar secular resonance. The long-term evolution of 24 BDS-3 MEO satellites without active control is simulated by the double-averaged Hamiltonian dynamical model. The simulation results show that some of the satellites could enter the Earth's atmosphere as their eccentricities increase. On the contrary, some other satellites have stable orbits during the long-term evolution. The effects of different e0, i0, ω0, and Ω0 on the long-term evolution are investigated, respectively. The results show that when e0 is larger, the eccentricity reaches emax faster; and the variations in e0 or ω0 don't change the values of the resonance angle in resonance. However, the change of i0 and Ω0 will change the values of the resonance angle in resonance. The maximum eccentricity method is used to study the influences of different initial conditions (including initial orbital elements and initial epoch) on the long-term evolution of MEO satellites. The results show that the changes of i0, omega0, and Omega0 affect the distribution of emax in the (Ω0, ω0) space. In the (Ω0, ω0) space, if the initial ΩM changes, the shape of the emax map changes, but the maximum value of emax barely changes. Apart from the region with large values of emax in the (Ω0, ω0) space, there also exist regions with small values of emax, where the differences between emax and e0 are very small.
Soil N2O and N2 emissions during anaerobic soil disinfestation period in a greenhouse vegetable production system: quantified by in situ 15N labeling method
Authors: Li Xue , Li Jin , Wang Yingying , Kang Ronghua , Sun Keping , Huang Kai , Fang Shuo , Chen Xin , Quan Zhi , Fang Yunting 
Published: March 2024

Abstract

Background and Aims: Greenhouse vegetable production (GVP) is expanding worldwide. The high application of nitrogen (N) fertilizers has caused soil diseases and nitrate residue. Farmers usually adopt anaerobic soil disinfestation (ASD), involving organic carbon addition, extensive irrigation, plastic films laying, and greenhouse sealing during the summer fallow. These conditions may promote denitrification, causing nitrous oxide (N2O) and dinitrogen (N2) emissions. However, this is rarely reported.
Methods: We used ¹⁵N labeling for in situ monitoring of N₂O and N₂ emissions during ASD in a GVP system in Shouguang, Northern China. Two treatments were implemented: conventional organic fertilization (Fertilizer) and a control (No-fertilizer), with continuous monitoring over 14 days.
Results: Within 14 days, cumulative gaseous N emissions in Fertilizer and No-fertilizer treatments were 0.82, 0.47 kg N ha-1 for N2O, and 40.7 and 25.5 kg N ha-1 for N2, respectively. Organic fertilization significantly increased N2O and N2 emission. From days 1–6, the predominant gaseous N was N2, with an N2O/ (N2O + N2) ratio (RN2O) between 0.007 and 0.015. From days 7–14, N2O proportion increased, with RN2O ranging from 0.21 to 0.75. Isotopic information showed that denitrification contributed to 48.9%–51.2% and 27.1%–36.7% of total N2O and N2 emissions. The structural equation model showed that high soil temperature during ASD significantly reduced N2O emissions.
Conclusion: Our findings emphasize the importance of N2 emissions in N loss and provide a basis for studying the fate of N, as well as developing measures to reduce N2O emissions within GVP systems.

Published: March 2024

Abstract

Background and aims Several investigations have assessed the soil organic carbon (SOC) content in forest soil. However, very few studies have explored the spatial variability of SOC content in forest soil using deterministic and geostatistical techniques. Telangana hosts various forest types, including dry deciduous scrub, dry teak forest, southern dry mixed deciduous forest, and non-forest areas. The present investigation aims to identify the best-fit model for SOC content distribution and examine how various forest types influence SOC content in forest soils in Telangana, India.
Methods The air-dried soil samples were analyzed for their SOC content using the wet digestion method. Deterministic and geostatistical methods used to assess the spatial distribution of SOC content in unsampled regions. Data were utilized to create spatial SOC maps using five interpolation methods: Inverse Distance Weighting (IDW), Ordinary Kriging (spherical, gaussian, and exponential), and Empirical Bayesian Kriging (EBK). The accuracy of these models was evaluated through cross-validation, semivariogram and considering metrics like coefficient of determination (R2) and the mean error (ME) and root mean square error (RMSE).
Results The order of SOC content was observed as follows: southern dry mixed deciduous forest > dry teak forest > dry deciduous scrub > non-forest for all soil depths, except at 30–60 cm. The results indicate that the EBK model has the highest R2 value (0.228) followed by OK- Spherical (0.219) and Exponential (0.216) for a soil depth of 0-30 cm. The OK-spherical model has the highest R2 value (0.139) followed by OK- Gaussian (0.135) and EBK (0.132) for a soil depth of 30-60 cm, and IDW has the highest R2 value (0.168) followed by OK- exponential (0.144) and EBK (0.135) for a soil depth of 60-90 cm.
Conclusion The study examined soil organic carbon (SOC) content and its spatial distribution across various forest types in Telangana, utilizing deterministic and geostatistical methods. Southern dry mixed deciduous forests exhibited higher SOC content, whereas lower SOC content were observed in dry deciduous scrub and non-forest areas. Evaluation of interpolation methods indicated that geostatistical methods (EBK and OK) outperformed IDW at soil depths of 0-30 cm and 30-60 cm, while the deterministic method (IDW) performed well at a depth of 60-90 cm. Increasing sampling points and incorporating elevation or topographical information could improve the accuracy of the interpolation model, emphasizing the importance of using both deterministic (IDW) and geostatistical (OK and EBK) methods for generating the SOC content spatial distribution map in the entire study area.

Published: March 2024

Abstract
Detection and monitoring of toxic and exhaust gases are crucial for energy and environmental conservation. Low-power, inexpensive gas sensors are in high demand. Metal oxide gas sensors are gaining interest due to their high selectivity and sensitivity. This research work aims to synthesize and characterize metal oxides, specifically thorium(IV) oxide, iron(III) oxide, and FTMMO, which is a mixed metal oxide consisting of iron and thorium. The synthesis of nanoparticles is accomplished using the co-precipitation method with a microwave reaction system. The resulting nanoparticles are subsequently characterized utilizing various analytical techniques such as FT-IR, UV-VIS (DRS), FE-SEM, EDAX, AFM, and XRD analysis. The cubic geometry of ThO2 and the face-centered rhombohedral structure of α-Fe2O3 nanoparticles were verified by XRD analysis. In order to investigate the utilization of iron(III) oxide, thorium(IV) oxide and iron thorium mixed metal oxides (FTMMO) are used to recognizes of ammonia and sulfur dioxide with the help of electrochemical method in the basic medium. The binding behavior of metal oxides and ovalbumin were investigated using UV-visible adsorption and fluorescence spectral techniques. The binding constant (Kb), Stern-Volmer constant (Ksv), and fluorophore quenching rate constant (kq) were calculated with the help of spectral data. Using the disc diffusion technique, research has been carried out to investigate the exceptional antibacterial activities of prepared metal oxides and mixed metal oxides against the different bacterial strains.

Abstract

This study aimed to investigate the impact of partially substituting fish meal (FM) and soybean meal (SBM) in the diet with fermented soybean meal (FSBM) on growth, feeding preference, protease activity, and their correlation with gastric evacuation in giant freshwater prawn, Macrobrachium rosenbergii. A 55-day feeding trial was conducted with eight isonitrogenous and isoenergetic diets, followed by a gastric emptying experiment. The results showed that the control group (containing 30% FM and 18% SBM) exhibited the highest feeding preference index, while the preference index of all diets demonstrated an initial decrease followed by an increase and subsequently a decline with increasing levels of supplemental fermented soybean meal. The SBM free group (almost devoid of soybean antigen proteins) showed the lowest preference index. Notably, there was no significant difference in feeding preference before and after domestication of the feed, and it was consistent with the trend of feeding rate. All the presented findings indicated that the inclusion of fish meal is a crucial factor influencing the feeding preference of M. rosenbergii. The excessive incorporation of fermented soybean meal in the diet led to an aversion towards feeding, which significantly contributes to the decline in growth rate.Short-term domestication (55 days) did not significantly alter the feeding preference of M. rosenbergii towards fermented soybean meal. However, when fermented soybean meal replaced fish meal and soybean meal, the individual action or interaction between antigenic proteins and other anti-nutritional factors resulted in varying changes in digestive enzyme activity and gastric evacuation dynamics.

Abstract

Upper extremity complications are often a problem in robot-assisted pelvic surgery (RAPS) with the lithotomy-Trendelenburg position (LT-position). This study focused on upper extremity contact pressure (UEP) and examined the relationship between UEP and upper extremity complications. From May 2020 to April 2022 at the University of Tokyo Hospital, UEP was measured in 155 patients undergoing RARP and 20 patients undergoing RARC. A total of 350 sets of UEP were investigated in this study. UEP was measured using a portable interface pressure sensor (Palm QR , Cape CO., Kanagawa, Japan) in the preoperative lithotripsy position (L-position), preoperative LT-position, and postoperative L-position. UEP was increased in the preoperative LT-position than in the preoperative L-position (right side 5.2 mmHg vs. 17.1 mmHg, left side 5.3 mmHg vs. 17.1 mmHg, P < 0.001, respectively), and was decreased in the postoperative L-position than in preoperative LT-position (right side 17.1 mmHg vs. 10.8 mmHg, left side 17.1 mmHg vs. 10.6 mmHg, P < 0.001, respectively). Eleven upper extremities developed shoulder pain. UEP of the preoperative LT-position tended to be higher in the upper extremity exhibiting shoulder pain (25.6 mmHg (15.4-30.3) vs. 17.1 mmHg (12.0-24.4) P = 0.0901). UEP measurements may help prevent postoperative shoulder pain.

Published: March 2024

Abstract

Phosphate is a non-point pollution source that primarily arising from agricultural waste water run-off and industrial effluents which proliferate the natural eutrophication. There is a need of effective monitoring of excessive phosphate release into aquatic environment. Some developments in direct electrochemical sensing have recently been made where the protocols often rely on time-consuming and complicate process for electrode fabrication while using some toxic metals. This article outlines efficient strategy for preparation of sensing electrodes for quick-responsive and real-time detection of phosphate ions based on conductive polyaniline (PANI) with biocompatible iron oxide (Fe2O3), zinc oxide (ZnO) and zinc ferrite (ZnFe2O4). It has been shown that the electrochemical integration of metal oxide particles into the porous PANI backbone offers several advantages, including high selectivity for target ions and rapid response to analytes in less than 50 seconds, along with low limit of detection (LOD). Among the different sensor electrodes LOD value was found to be 2.95 x 10− 7 M, with high diffusion coefficient values of 9.6x10− 4 cm2/s and high sensitivity of 1.22 A/M·cm² for PANI-ZnFe2O4@AuS modified gold sheet (AuS) electrode. The sensing features of the as-prepared PANI-ZnFe2O4@AuS electrode can be attributed to the uniform distribution of metal oxide particles within the PANI matrix, which produces effective synergistic effect for phosphate ions sensing.
Effect of terahertz radiation on drug activity in bacterial cells

Published: March 2024

Abstract
The biological effects of terahertz (THz) waves have been increasingly studied in recent years with the development of THz wave generation and detection technology. THz waves have been reported to change membrane permeability and induce conformational changes in protein molecules. Drugs action on cells involves membrane permeability, and we therefore investigated the effect of THz waves on the activity of the cytotoxic drug bleomycin on Escherichia coli. 0.46 THz radiation with an average power of 2.5 W/cm2, pulse duration of 10 ms, and a repetition frequency of several Hz was noncytotoxic to E. coli cells. However, 0.46 THz radiation enhanced the cytotoxic activity of bleomycin in E. coli cells, and the drug-enhancing effect depended on the power density of the THz waves. The effect of THz radiation on drug uptake into cells was investigated based on the activity of the drug remaining in the culture medium after THz radiation or non-radiation. The activity of the drug remaining in the culture medium after THz radiation did not differ from that remaining after non-radiation. This indicates that THz radiation does not affect the bacterial cell-membrane permeability to bleomycin. Thus, this study suggests that 0.46 THz radiation enhances the cytotoxicity of bleomycin towards E. coli cells and may influence the mechanism of bleomycin action within cells rather than affecting drug uptake.

Authors: Abdolhosseini Hesam , Zarandi Hamid R. 
Published: March 2024

Abstract

Managing the complex interconnections found in contemporary chip designs is achievable through the utilization of network-on-chip (NoC) architectures. Optimizing NoC configuration is critical for balancing reliability and latency. This paper presents a study on simultaneously optimizing NoC to improve reliability and reduce average packet latency, while considering buffer size constraints. Buffer size significantly impacts latency, cost, and reliability, making it a key element for optimization. To validate latency estimates, we compared against the Garnet2.0 simulator. Optimization utilized the NSGA-II algorithm to concurrently optimize multiple objectives like reliability and latency. The buffer size in NoC input ports constrained optimization. MATLAB was selected for implementing the algorithm due to its optimization libraries and user-friendly interface. We provide extensive findings for different NoC dimensions when subjected to both uniform and hot-spot traffic. This study contributes to designing robust, efficient on-chip communication, which is essential as computing systems demand increases.
