Greenlip abalone (Haliotis laevigata) are high-value marine bivalves. In order to preserve the quality, most of edible aquatic animals were transported in live conditions. In addition, keep the condition at low temperature is considered as the best way to reduce the stress level of the animal. However, this method is still poorly understood in greenlip abalone. The present study examines the effects of pre-cooled (±14 °C) and non-precooled (±21 °C) temperature treatments on survival and physiological responses such as total haemocyte count, phagocytic assay, lysosomal assay, and lactate of live abalone during transport simulation at time intervals of 0, 12, 24, 36 and 48 hours. Results indicated that pre-cooling treatment prior to transport increased the survival rate and minimised weight loss. The lactate levels were significantly higher in the abalones that were not cooled prior to transport. Both animals that were pre-cooled and those that were not cooled prior to aerial transport simulation showed increases in total haemocyte count and a decrease in phagocytic activity, which indicates that live transport has an impact on their immunity. The present study indicated that the importance of pre-cooling treatment before transportation to preserve the condition of live abalone.

The cost incurred in raising fish to table size in fish farming has been a major issue both to the farmers and the consumers at large. To address this concern this study assessed the growth performance of Clarias gariepinus fed varying inclusion levels of water melon (Citrullus lanatus) bark. A total of 120 samples with 0.75±0.209g mean weight and 3.9±0.31cm mean total length were acclimated in the laboratory for a period of 14 days during which they were fed to satiation twice daily. Subsequently, they were randomly assigned to the five treatments diets with replicate in each case at 12 fish per treatment; T1 with 00%, T2 with 25%, T3 with 50%, T4 with 75% and T5 with 100% levels of inclusion as possible replacement for equal weight of soybeans. The set-up ran for 12 weeks and the growth parameters (lengths and weight) were determined on weekly basis. Weight gain and specific growth rate were calculated. The physico-chemical parameters of the test media were also determined on weekly basis according to standard methods. The data generated were subjected to one way analysis of variance. From the results: Treatments with 50% and 75% inclusion levels performed slightly better than the control in terms of weight gain. The highest weight obtained in T2 and T3 were 31.71±0.35g and 31.48±1.71g, respectively. Similarly, the optimum requirement of watermelon bark level in the formulation of practical diets for improved growth of C. garienpinus were 50% and 75% in terms of lengths. T2 and T3 had the highest total lengths with 19.05±0.35cmand 15.90±2.80cm, respectively; while the standard lengths in T2 and T3 were 13.50±0.35cmand 13.45±2.85, respectively. Hence, water melon bark can replace the more expensive soybean thereby reducing cost of production and curtail environmental filth and disposal problems associated with watermelon bark waste in Nigeria.

All organizations rely on their reputation to strengthen their image and increase consumer trust and credibility in their products and/or services. In this context, developing an Ethical Brand (EB) and a Corporate Reputation (CR) continues to be a major challenge. Therefore, this research aims to investigate empirically how trust affects EB and CR. This study used secondary data from the Authenticity Gap Report (AGR), collected on-line in 160 Brazilian organizations, using a structured questionnaire to a non-probability sampling from 20 different industries with 1.328 Engaged Consumers. Different references were used for analysis: (i) the Trust model in buyer-seller relationships; (ii) the Ethical Reputation Brand model; and (iii) the CR Ranking Index (MERCO). The results indicated that three of five dimensions of the Trust model represented good CR indicators. From the 20 different industries analyzed, three have the best average, according to the MERCO Ranking and the three combined indicators from the AGR. Results demonstrated the role of authenticity, trust, and industry as a fundamental element to EB and CR.

Los dispositivos digitales han adquirido un papel fundamental en las dinámicas sociales entre los adolescentes, aumentando la prevalencia de conductas de riesgo como el ciberacoso. Aunque su estudio ha aumentado en las últimas décadas, aún son escasos los trabajos centrados en conocer los efectos de formas de cibervictimización sutiles, como el ciber-rumor. Los objetivos del estudio fueron, primero, examinar si las víctimas de ciber-rumor presentan mayores niveles de síntomas internalizantes, y segundo, explorar si la resiliencia actúa como mediadora de dicha asociación, controlando el efecto del sexo. Un total de 558 escolares (54.3% chicas) con edades entre 13 y 17 años (M = 14.65 años; DT = 1.19) participaron en el estudio. El tratamiento de datos siguió un modelo de mediación a través de PROCESS. Los resultados evidenciaron que las víctimas de ciber-rumor presentaron niveles más altos de depresión, ansiedad y estrés que los adolescentes que indicaron no haber sido víctimas de ciber-rumor. Los modelos de mediación mostraron que la resiliencia medió en la relación entre ser víctima de ciber-rumor y los niveles de depresión y ansiedad, pero no con los de estrés. No se encontró que el sexo moderara dichos efectos. En conclusión, estos resultados subrayan la importancia de atender a los fenómenos de ciberagresión dado sus efectos sobre el bienestar social y emocional identificados en este estudio. De ello se deriva la necesidad de diseñar programas de prevención que incluyan entre sus estrategias la promoción de habilidades para el afrontamiento del ciber-rumor.

Published: April 2022

This study was undertaken to understand the reasons related to typology and organization in physical practice taking into account the perceptions of the older adults. Four focus groups were conducted with a total of 39 older adults. The study participants consisted of 30 women and 9 men (mean age of men and women was M = 68 and 67.1, SD = 4.7 years, respectively), from three contexts. These environments were rural area, a neighbourhood at risk of exclusion and a high socio-economic urban context. The methodological analysis is inductive, emergent, delineating the speeches from the specific to the general, through the process of codifying the grounded theory. Several factors appeared after the emergent analysis of the interventions of older adults. In this line, social support and goal setting were prominent factors that served as facilitators for adherence to physical exercise programs. The encouragement and company of others were factors that facilitated adherence to the physical exercise. Relating to sex differences, older male adults prefer to exercise alone, compared to women. Researchers and health professionals can use these results to tailor motivational messages and promote health-enhancing behavioural interventions for older adult populations.

Abstract
Background: Millions of Syrians have been forcibly displaced since March 2011. Most of them live in neighbouring countries, including Jordan, with adolescent girls and women as the most vulnerable populations. After almost nine years of the protracted crisis, it was essential to examine available evidence around the effectiveness of MISP/SRH interventions implemented for them in Jordan to inform the humanitarian community and the government by identifying best practices, essential gaps, bottlenecks, and lessons learnt. Methods: Using a previously validated MISP/SRH survey tool and combining quantitative and qualitative research methods, an assessment was conducted in 2018 in four governorates of Jordan to evaluate the availability of MISP/SRH interventions/programs. Data were obtained by trained data collectors and analyzed in SPSS-IBM.Results: Overall, 58 key informants (KIs) from 15 different entities/agencies participated in the assessment. KIs/respondents had various levels of knowledge/sources of information about the MISP/SRH services and had variable engagement in implementation. The results of this assessment highlighted significant knowledge gaps about the implementation of MISP objectives and priorities, even after almost nine years of the onset of the crisis. Among different MISP activities, family planning, maternal health, condom distribution, and newborn health services had the highest level of preparation and implementation, while availability of antiretrovirals (ARVs) for prevention of mother-to-child transmission (PMTCT) and access to safe blood had the lowest level of preparation and implementation. This assessment also showed lack of national coordination in the provision of different SRH services, lack of a national plan for capacity building, and lack of adequate logistics support systems and funding. Conclusions: Important gaps in the knowledge and implementation of MISP/SRH activities continue to exist in Jordan almost nine years into the Syrian displacement. Areas in need of focus include: national coordination in the provision of SRH services, a national plan for capacity building, logistics support systems, and funding for MISP/SRH services provision. Additional funding needs include: Capacity building of service providers with focus on training activities around different MISP/SRH services, facilitating emergency preparedness, improving coordination, and improving referral systems.

Abstract
Background: In Japan, pulmonary Mycobacterium avium-intracellulare complex (MAC) disease is highly prevalent. This study aimed to evaluate the efficacy of Jiinshihoto (JST) for treating pulmonary MAC disease. Methods: Twenty-four patients, not receiving standard treatment for pulmonary MAC disease, were enrolled in this study; of these, 21 patients (3 patients dropped out of the study) were eligible and selected to participate. They were administered JST (3.0 g; Tsumura Co., Tokyo, Japan) three times per day for 12 months. Their weight, chronic obstructive pulmonary disease assessment test (CAT) score, NK cell activity, chest computed tomography (CT) results, blood sample results, Self-rating Depression Scale (SDS) scores, and State-Trait Anxiety Inventory (STAI) scores were measured: (i) before JST administration, (ii) after 3 months, and (iii) at the end of the study. Results: Before JST administration, the exacerbation group (n = 10 patients; 6 patients with worsened conditions at the end of the study and 4 patients who were switched to standard treatment during the study because of exacerbation) had a significantly low body mass index (BMI), mild depression, and high anxiety. The overall patient population showed no significant differences in the chronic obstructive pulmonary disease assessment score, body weight, or natural killer cell activity after 3 months of treatment; however, the SDS score improved significantly. At the end of treatment, the nutritional scores had worsened, but the SDS score improved significantly. Specifically, the SDS scores improved significantly only in the non-exacerbation group (n = 11 patients), and natural killer cell activity improved in the non-exacerbation group. Additionally, a comparison of the data of both groups before and after JST administration showed that the exacerbation group had significantly lower BMI and worse CT scores when using a BMI cutoff of 18.4 (sensitivity, 81.8%; specificity, 70%). Conclusion: Patients with a high BMI and low CT score at the time of initial diagnosis may benefit from JST treatment, which may significantly improve depression and immunity and prevent disease progression. Therefore, JST may be an effective treatment in selected pulmonary MAC patients.Trial registration: This study has been registered in the UMIN-Clinical Trials Registry (UMIN000033590, August 1, 2018).

Published: April 2022

Abstract
The study makes an effort to examine the association between education, health expenditure, GDP per capita, and pollution emissions for Pakistan from 1991 to 2019. The study uses a non-linear ARDL model to capture short-run and long-run asymmetric effects among variables. The findings confirm the existence of an asymmetric relationship among variables in the short-run and long-run. Positive shocks of education, health expenditures, and GDP per capita reveal that education and health expenditures have a negative influence on carbon emissions, however, GDP has a positive influence on carbon emissions in the long-run. On the other hand, negative shocks of education, health expenditures, and GDP per capita reveal that education has no significant impact on carbon emissions, while a decrease in health expenditures and GDP per capita leads to a reduction in carbon emissions in the long run. These results have imperative implications for analysts as well as management of the Pakistan economy.
Rheological behavior of a magnetorheological shear-thickening fluid (MRSTF) and dynamic characteristics of an MRSTF damper

Published: April 2022

Abstract
In this study, a magnetorheological shear-thickening fluid (MRSTF) containing nano-grade fumed silica and polyethylene glycol mixed with different iron powder mass fractions was first evaluated, and the rheological behavior of the MRSTF was analyzed. The viscosity amplitude of thickening with the MRSTF decreased with increasing magnetic field strength. When the magnetic field strength of the MRSTF reached 197 mT, the thickening effect was eventually eliminated. An increasing content of carbonyl iron powder effectively increased the viscosity of the fluid under a weak magnetic field environment. And then magnetorheological shear-thickening damper (MRSTD) was designed and its dynamic characteristics were studied using an MTS809 fatigue testing machine. The results indicated that the damping force of the MRSTD changed with the vibration frequency, amplitude, and magnetic field strength. Finally, according to the mechanical characteristics of the MRSTD, linear and nonlinear damping models were established based on the energy storage stiffness and energy dissipation stiffness, respectively. And the results of the two fitting functions were compared with those of the experiments. The nonlinear damping model was found to better replicate the nonlinear stiffness, nonlinear damping, and shear rate-related characteristics of the MRSTD. The results of this study provide guidance for future theoretical and applied research into MRSTDs.

Published: April 2022

Abstract
Autonomous-rail Rapid Transit (ART) is a new medium-capacity rapid transportation system with punctuality, comfort, convenience, but low-cost construction. Combined velocity planning is a critical approach to meet the requirements of energy-saving and punctuality. An ART velocity pre-planning and re-planning strategy based on the combination of dynamic programming (DP) and pseudospectral (PS) method is proposed in this paper. Firstly, the longitudinal dynamics model of ART is established by a multi-particle model. Secondly, the DP algorithm with global optimal characteristics is adopted as the pre-planning strategy. A model for determining number of the optimal collocation points of the real-time PS method is proposed to improve the energy-saving effect while ensuring the computation efficiency. Then the enhanced PS method is utilized to design the velocity re-planning strategy. Finally, simulations are conducted in typical scenario with sloping roads, traffic lights, and intrusive of pedestrian. The simulation results indicate that the ART with the proposed velocity trajectory optimization strategy can meet the punctuality requirement, and obtain better economy efficiency compared with the constant speed strategy.

Published: April 2022

Abstract

Parking difficulties have become a social issue that people have to solve. Automated parking system is practicable for quick parking operations without a driver which can also greatly reduces the probability of parking accidents. The paper proposes an Lyapunov-based nonlinear model predictive controller embedding an instructable solution which is generated by the modified rear-wheel feedback method (RF-LNMPC) in order to improve the overall path tracking accuracy in parking conditions. Firstly, A discrete-time RF-LNMPC considering the position and attitude of the parking vehicle is proposed to increase the success rate of automated parking effectively. Secondly, the RF-LNMPC problem with a multi-objective cost function is solved by the Interior-Point Optimization, of which the iterative initial values are described as the instructable solutions calculated by combining modified rear-wheel feedback to improve the performance of local optimal solution. Thirdly, the details on the computation of the terminal constraint and terminal cost for the linear time-varying case is presented. The closed-loop stability is verified via Lyapunov techniques by considering the terminal constraint and terminal cost theoretically. Finally, the proposed RF-LNMPC is implemented on a self-driving Lincoln MKZ platform and the experiment results have shown improved performance in parallel and vertical parking conditions. The Monte Carlo analysis also demonstrates good stability and repeatability of the proposed method which can be applied in practical use in the near future.
