Published: October 2022

Viruses, as intracellular parasites, rely on the host organism to complete their life cycle. Although over 70% of plant viruses are transmitted by insect vectors, the role of vector energy metabolism on the infection process of insect-borne plant viruses is unclear. In this study, full-length cDNAs of three energy metabolism-related genes (LsATPase, LsMIT13 and LsNADP-ME) were obtained from the small brown planthopper (SBPH, Laodelphax striatellus), which transmits the Rice stripe virus (RSV). Expression levels of LsATPase, LsMIT13 and LsNADP-ME increased by 105%, 1120% and 259%, respectively, due to RSV infection. The repression of LsATPase, LsMIT13 or LsNADP-ME by RNAi had no effect on RSV nucleocapsid protein (NP) transcripts or protein levels. The repression of LsATPase caused a significant increase in LsMIT13 and LsNADP-ME transcript levels by 230% and 217%, respectively, and the repression of LsMIT13 caused a significant increase in LsNADP-ME mRNA levels. These results suggested that the silencing of LsATPase induced compensatory upregulation of LsMIT13 and LsNADP-ME, and silencing LsMIT13 induced compensatory upregulation of LsNADP-ME. Further study indicated that the co-silencing of LsATPase, LsMIT13 and LsNADP-ME in viruliferous SBPHs increased ATP production and RSV loads by 182% and 117%, respectively, as compared with nonviruliferous SBPHs. These findings indicate that SBPH energy metabolism is involved in RSV infection and provide insight into the association between plant viruses and energy metabolism in the insect vector.

Solid organ transplant recipients (SOTRs) show higher rates of COVID-19 breakthrough infection than the general population, and nowadays, vaccination is the key preventative strategy. Nonetheless, SOTRs show lower vaccine efficacy for the prevention of severe COVID-19. Moreover, the emergence of new SARS-CoV-2 variants of concern has highlighted the need to improve vaccine-induced immune responses by the administration of repeated booster doses. In this study, we analyzed the humoral and cellular responses in a cohort of 25 SOTRs, including 15 never-infected SOTRs who received the fourth dose of the mRNA vaccine and 10 SOTRs who contracted SARS-CoV-2 infection after the third dose. We analyzed the serum IgG and IgA levels through CLIA or ELISA, respectively, and the Spike-specific T cells by ELISpot assay. We report a significant increase in anti-Spike IgG and no differences in IgA secretion in both groups of patients before and after the booster dose or the natural infection. Still, we show higher IgA levels in recovered SOTRs compared to the fourth dose recipients. Conversely, we show the maintenance of a positive Spike-specific T-cell response in SOTRs who received the fourth dose, which, instead, was significantly increased in SOTRs who contracted the infection. Our results suggest that the booster, either through the fourth dose or natural infection, in vulnerable poor responder SOTRs, improves both humoral and cellular-specific immune responses against SARS-CoV-2.

Published: October 2022

Older adults are more likely to have influenza and respond less well to the flu vaccine. We conducted this study to investigate whether pre-influenza vaccination metformin use had an effect on influenza and relevant complications in older adults with type 2 diabetes mellitus. Propensity score matching was used to identify 28,169 pairs of metformin users and nonusers from Taiwan’s National Health Insurance Research Database from 1 January 2000 to 31 December 2018. We used Cox proportional hazards models to calculate the risks of hospitalization for influenza, pneumonia, cardiovascular disease, ventilation, and mortality between metformin users and nonusers. Compared with metformin nonusers, the aHRs (95% CI) for metformin users at risk of hospitalization for influenza, pneumonia, cardiovascular disease, invasive mechanical ventilation, death due to cardiovascular disease, and all-cause mortality were 0.60 (0.34, 1.060), 0.63 (0.53, 0.76), 0.41 (0.36, 0.47), 0.56 (0.45, 0.71), 0.49 (0.33, 0.73), and 0.44 (0.39, 0.51), respectively. Higher cumulative duration of metformin use was associated with lower risks of these outcomes than no use of metformin. This cohort study demonstrated that pre-influenza vaccination metformin use was associated with lower risks of hospitalizations for influenza, pneumonia, cardiovascular disease, mechanical ventilation, and mortality compared to metformin nonusers.
Sustainable Development of Coastal Areas: Port Expansion with Small Impacts on Estuarine Hydrodynamics and Sediment Transport Pattern
Authors: da Silva Pablo Dias , Fernandes Elisa Helena , Gonçalves Glauber Acunha
Published: October 2022

With the expansion of global trade and the growing traffic of increasingly larger ships to meet this demand, the need to expand port infrastructure appears as the main alternative. In this way, dredging operations for the maintenance and deepening of navigation channels, as well as the expansion of evolution basins and berthing wharf areas become fundamental, generating large amounts of material removed from the bottom. Aiming at port expansion based on a sustainable development and minimization of the environmental impacts generated by these operations, it is necessary to seek alternatives for the destination of large volumes of dredged material. A sustainable alternative is to dispose these volumes on land in order to expand coastal areas (such as fattening beaches) and mooring pier areas. The present work presents a numerical modeling case study using the TELEMAC-3D model coupled to the suspended sediment module SEDI-3D. As an alternative, an existing island (Ilha do Terrapleno) will receive material dredged from the access channel to the Port of Rio Grande (southern Brazil) and will have its mooring area expanded. The study evaluated the impact that this change in the island’s configuration would generate on the hydrodynamics and on the deposition patterns of fine suspended sediments in its surroundings and in the adjacent navigation channel. Results indicated that in the navigation channel adjacent to Ilha do Terrapleno, the new configuration promoted changes in the hydrodynamics with a decrease in the mean current velocity around the island and throughout the water column, mainly in the north and central portions of the channel. This difference decreased towards the southern portion of the channel. This change in local hydrodynamics promoted small changes in the suspended sediment deposition patterns and in the bottom evolution. Thus, the sustainable expansion of the Port of Rio Grande operational capacity considering the creation of 3600 m of berthing wharf areas and minimum environmental impact proved viable when considering the Ilha do Terrapleno proposed configuration. Furthermore, this idea offers the possibility to dispose in land 722,910 m3 of dredged material, a sustainable alternative to the Port of Rio Grande development, and an inspiration for the sustainable development of other ports worldwide.

Published: October 2022

A process of infiltration from the soil surface to form soil water is known as soil infiltration; this is the only way for plants to absorb and use soil water. This process is closely related to nutrient migration, surface runoff, and soil erosion. The objectives of this study were to quantify the effect of typical plant communities on soil infiltration performance, reveal the interaction between soil infiltration rate and soil characteristics and plant roots, and determine the primary influencing elements on the Xilamuren grassland. The ring knife method was used to determine the soil infiltration rate at the 0–30 cm soil layer of six typical vegetation communities. The results indicated that the infiltration rate of the Koeleria macrantha community was highest at the soil depth of 0–5 cm, while that of the Convolvulus ammannii community was lowest, reaching 4.25 mm·min−1 and 0.53 mm·min−1, respectively. The soil infiltration rate of different plant communities gradually declined with the increment of soil depth. The strongest correlations were found between bulk density, total porosity, organic matter, root characteristics, and soil infiltration rate. The bulk density, initial water content, capillary porosity, and clay content were the primary influencing factors acting on soil infiltration in the region. Other factors indirectly impacted the infiltration rate by modifying bulk density, which was a crucial limiting factor determining the infiltration rate in the research region. The study’s findings will give theoretical and practical assistance for the prevention and management of soil deterioration and grassland restoration in this area.

Published: October 2022

The special geographical environment of the Tibetan Plateau makes ground observation of Ground Water Storage (GWS) changes difficult, and the data obtained from the GRACE gravity satellites can effectively solve this problem. However, it is difficult to investigate the detailed GWS changes because of the coarser spatial resolution of GRACE data. In this paper, we constructed a 0.1° resolution groundwater storage anomalies (GWSA) dataset on the Tibetan Plateau from 2002 to 2020 based on a phased statistical downscaling model and analyzed the spatiotemporal variation and driving factors of the GWSA in order to better study the changes of GWS on the Qinghai Tibet Plateau. The results show that: (1) In the Tibetan Plateau and 12 sub-basins, the GWSA before and after downscaling show a very high correlation in time series and relatively good performance in spatial consistency, and the downscaled GWSA indicate a consistent trend with the measured groundwater level. (2) The GWSA on the Tibetan Plateau shows a downward trend (−0.45 mm/yr) from 2002 to 2020, and the variation trend of the GWSA in the Tibetan Plateau shows significant spatial heterogeneity. (3) The GWSA changes in the Tibetan Plateau are mainly dominated by natural factors, but the influence of human activities in individual sub-basins can not be ignored. Among the teleconnection factors, El Nino-Southern Oscillation Index (ENSO) has the greatest influence on the GWSA on the Tibetan Plateau.
Differential Response of Phaeodactylum tricornutum and Cylindrotheca fusiformis to High Concentrations of Cu2+ and Zn2+

Published: October 2022

Diatoms can be used as biosensors to assess aquatic environment quality, because they are widely distributed in almost all aquatic environments and show varied sensitivities toward heavy metal ions. The marine planktonic diatoms Phaeodactylum tricornutum (P. tricornutum) and Cylindrotheca fusiformis (C. fusiformis) are typical representatives of planktonic diatoms and benthic diatoms, respectively. C. fusiformis is very sensitive to changes in the concentration of heavy metal ions, and can be used as an indicator of the quality of the sedimental environment, while P. tricornutum can tolerate higher concentrations of heavy metal ions. To explore the potential difference in responses to heavy metal ions between planktonic and benthic diatoms, we compared the transcriptome of P. tricornutum and C. fusiformis under Cu2+ and Zn2+ treatment. The results indicated that P. tricornutum has several genes involved in ion transmembrane transport and ion homeostasis, which are significantly downregulated under Cu2+ and Zn2+ treatment. However, this enrichment of ion transmembrane transport- and ion homeostasis-related genes was not observed in C. fusiformis under Cu2+ and Zn2+ treatment. Additionally, genes related to heavy metal ion stress response such as peroxiredoxin, peroxidase, catalase, glutathione metabolism, phytochelatin, oxidative stress and disulfide reductase, were upregulated in P. tricornutum under Cu2+ and Zn2+ treatment, whereas most of them were downregulated in C. fusiformis under Cu2+ and Zn2+ treatment. This difference in gene expression may be responsible for the difference in sensitivity to heavy metals between P. tricornutum and C. fusiformis.

Published: October 2022

This study seeks to clarify the content characteristics, spatial distribution, potential sources and ecological risks of nitrogen, phosphorus and some heavy metals (As, Hg, Cd, Cr, Cu, Pb, Zn and Ni) in the sediments of Yueliang Lake. Nitrogen, phosphorus and heavy metals were analyzed in the surface and core sediments of Yueliang Lake. The present situation of heavy metal pollution and the degree of potential ecological risk in sediments was evaluated by the geo-accumulation index (Igeo) and potential ecological risk index (RI). The correlation (CA) and principal component analysis (PCA) methods were used to analyze the potential sources of the main pollutants among the heavy metals. The results show that the total nitrogen (TN = 2305 mg/kg) and total phosphorus (TP = 530 mg/kg) in the surface sediments of Yueliang Lake are at medium and low levels, respectively. The average content of organic matter was 2.17%, and the nutrient ratio was 6.90–11.92, which was significantly higher in the northwest than in the middle and east of Yueliang Lake, indicating that the organic matter was a mixture of endogenous aquatic plants and exogenous terrestrial plants in the sediments. From two evaluation indices (RI and Igeo) calculated using element contents, the heavy metals in the surface sediments were at a moderate ecological risk level. The level of Hg was moderately polluted, Pb and Cd were at the mildly polluted level, and Cu, Zn, As, Cr and Ni were at pollution-free levels. Except for Hg, the other elements in the core sediment are basically not polluting, and the whole is at the level of slight ecological risk. The sources of heavy metals in the sediments are roughly divided into three categories. The first category is natural sources, including Cr, Ni, As, Zn and Cu. The second category includes Cd and Hg and the main sources are highly related to energy development and agricultural activities. The third category is light Pb pollution caused by vehicular traffic and coal-related industrial activities. Therefore, the pollution problems caused by tourism development and agricultural activities should be considered in the future development of the Yueliang Lake area.

Published: October 2022

Femtosecond laser ablation (FLA) has been playing a prominent role in precision fabrication of material because of its circumvention of thermal effect and extremely high spatial resolution. Molecular dynamics modeling, as a powerful tool to study the mechanism of femtosecond laser ablation, still lacks the connection between its simulation results and experimental observations at present. Here we combine a single-shot chirped spectral mapping ultrafast photography (CSMUP) technique in experiment and a three-dimensional two-temperature model-based molecular dynamics (3D TTM-MD) method in theory to jointly investigate the FLA process of bulky gold. Our experimental and simulated results show quite high consistency in time-resolved morphologic dynamics. According to the highly accurate simulations, the FLA process of gold at the high laser fluence is dominated by the phase explosion, which shows drastic vaporized cluster eruption and pressure dynamics, while the FLA process at the low laser fluence mainly results from the photomechanical spallation, which shows moderate temperature and pressure dynamics. This study reveals the ultrafast dynamics of gold with different ablation schemes, which has a guiding significance for the applications of FLA on various kinds of materials.

Published: October 2022

CV. Gavra Perkasa is a manufacturing industry with the finished product in the form of turning. The number of sales transactions will affect the inventory of raw materials. The problem with the company is that the company's ability to predict the amount of raw materials that must be available in the following month is not optimal due to fluctuating demand. This problem will have an impact on planning inventory inventory during the production process and recording inventory usage to optimize storage costs. This study aims to plan inventory demand in the future and to plan inventory use using the Moving average  and Exponential smoothing methods. These two methods are used because the results of the demand data plot show a stationary data pattern. The accuracy of the forecasting results was analyzed with the smallest MSE, MAD, and MAPE results. Based on the analysis results, the 5-month MA method is the most accurate with prediction results in 2017 of 57000 units with MAD, MSE, and MAPE values of 3684.21, 24345260, and 0.07.

Published: October 2022

Agam Teknik is a business that produces dump trucks, where at the iron plate cutting site there are no work facilities that support operators in carrying out their work activities which result in complaints of skeletal muscles. In the production process activities, it was found that there were semi-automatic activities, namely the process of cutting iron plates using a welding torch on the floor so that the operator worked in a squatting state, bent knees and ankles, raised shoulders and bent body so that the work posture experienced by the operator was not ergonomic. The aims of this study were (1) to identify complaints of musculoskeletal disorders experienced by dump truck manufacturing operators using the Standard Nordic Quistionaire (SNQ), (2) to determine the value of the operator's work posture using the REBA method with the help of Ergofellow Software, and (3) to design ergonomic work facilities. SNQ is a method used to identify the source of muscle fatigue at work, while the REBA method is used to determine risk factors related to overall body posture at work. The tool used is Ergofellow Software which serves to analyze quickly and easily in terms of postural. The results of the identification of operator complaints during the dump truck manufacturing process, obtained two work stations where the operator felt very sick and painful complaints, namely at the cutting station and pressing the iron plate. Based on the identification results obtained eight operator complaints, namely extreme pain and pain including pain in the left and right shoulders, neck pain, left upper arm pain, back pain, left hand pain, right knee pain, left calf pain, and pain in the right leg. Recommendations from these conditions are to design an iron plate cutting work facility with the addition of a table for cutting iron plates, and to redesign the iron plate pressing station by adjusting the press tool used by the operator for pressing iron plates.

The COVID-19 pandemic has changed the shape of the world of work. This change makes 100% of universities in Indonesia conduct online learning, but some academic administrative activities are still carried out on campus. With this condition, higher education management faces two things that must be considered, namely the health of employees who are still working on campus, and teaching staff who work at home. The purpose of this study is to make the right size in measuring the Safety Management System in Higher Education in dealing with the threat of the virus and to examine the role of Management Commitment to the implementation of the Safety Management System and to examine the role of Safety Culture in the implementation of the Safety Management System. This research is a survey research using a questionnaire, with data analysis method using Path Analysis and Binomial Regression and validity test using Confirmatory Factor Analysis. From the results of this study, it can be seen that a high Safety Culture cannot improve Safety Performance in Higher Education during the pandemic, which is different from Management Commitment and the Safety Management System which are the main determinants of employee Safety Performance during the pandemic. Management's commitment can indeed improve employee Safety Performance during a pandemic, but in improving Safety Performance during a pandemic, performance will be higher if the management commitment pushes the Safety Management System first, then it will increase the organization's Safety Performance with the virus pandemic.

Published: October 2022

Information system (IS) is seen to be one of the major factors that operate the organization systematically and has contributed a positive impact in improving the performance of an organization. Due to its importance, many studies have done in ensuring the best method employed in its development and comply with its quality. The challenges are to identify a method in evaluating the quality of the systems and this has become the interest of many researchers. There are various evaluation models exist, in fact, various evaluation theories have been proposed in different disciplines and perspectives. However, the existing evaluations are based from the user's perspective and often ignored the point of view from the system developers. System developers are the persons who are responsible to develop the system. They are responsible in ensuring the systems comply with its quality and making the system usable, effective and error free. System developers also ensure that the developments are according to the user specifications. Therefore, their views in determining the quality of the system should be taken into account. Thus the aim of this study is to propose an evaluation model for IS based on system quality factor from the perspective of system developers. The findings showed that the system quality factors such as data quality, user satisfaction and organizational needs are the factors that should take into account when proposing IS evaluation models. The findings from this study could be served as a guideline to the system development team in producing quality systems that are able to enhance organizational performance.

A BENCHMARKING ANALYSIS OF CORPORATE SOCIAL AND ENVIRONMENTAL REPORTING OF MALAYSIAN TELECOMMUNICATION SERVICE PROVIDERS
Authors: Hashim Fathyah , Ng Teck Huai
Published: October 2022

The main purpose of this paper is to explore corporate social and environmental reporting (CSER) practices among Malaysian telecommunication companies. Using benchmarking analysis, the paper attempts to identify the current status of the CSER practices in comparison with an identified benchmark company. The empirical examination encompasses a sample that includes the annual reports of four telecommunication companies from 2013 to 2017. A content analysis approach has been applied to these annual reports. The findings show that categories of “corporate governance” and “community” received the highest amount of disclosure over the period of five years, while the least amount of disclosure was found in the “employee relation” category. It is recommended that low-level disclosures on employee relation be given more prominence by policymakers, management, and other relevant stakeholders.

In football, including handicapped football, effective play requires players to be able to handle the ball at high speed and perform multiple "explosive" high-speed movements. In disabled football, the problem of developing and evaluating the speed-strength abilities of football players with cerebral palsy is relevant. At present, in the period of active digitalization of education and sports, it is necessary to master and implement digital technologies in sports practice. The study was conducted on the basis of the Zenit football club for the disabled in the city of Izhevsk on an experimental group of 10 football players with cerebral palsy aged 15-18. The article substantiates the necessity and proves the possibility of using the test "bicycle ergometry on MONARK 894E" to measure the speed-strength abilities of football players with cerebral palsy. The basic requirements for tests are considered. Standardization is ensured by testing in the laboratory on the same bicycle ergometer. To check the validity, control motor speed-strength tests were chosen: “Long jump from a place with a push with two legs” and “Run for 30 meters”. Correlation analysis showed a strong statistical relationship between control motor tests and experimental one - "testing on a bicycle ergometer" (multiple correlation coefficient R XYZ =0,87 ). As an indicator of reliability, we took the Bravais-Pearson Correlation coefficient for two measurements on the MONARK 894E bicycle ergometer, which showed a strong relationship between them (r xg=0,99) . On the basis of the GTO standards, a “five-point” interval rating scale was developed according to the indications “maximum alactate power in W” for the experimental test. The conclusions on the conducted research are formulated.

In this study, a 10 nm u-GaN etching buffer layer was designed and inserted into the standard p-GaN/AlGaN/GaN high electron mobility transistor structure to improve the p-GaN etching process. The experimental result shows that the device with the u-GaN layer can avoid the over-etched issue, further improving the uniformity of the etching profile and the ON-resistance of the devices. The simulation result indicates that the drain current would slightly increase due to reduced conduction band raising when the u-GaN layer is inserted. In sum, the process uniformity can improve when the u-GaN layer is inserted and in the meantime, excellent device characteristics are maintained.
Consumption of Local Foods: Unpremeditated, Abetted, or Deliberate? A Case of Nairobi and Machakos (Kenya)

Locavores is a term often using to describe a person who diet consists only or principally of locally grown or produced food. There are numerous definitions of "local food," but the concept is primarily based on distance. Many people prefer to buy food locally, beginning in their own community and progressing to the region, province, country, and so on. Consumption of local food products is defined as products manufactured in a given geographical space using methods, tools, and unique materials to that space. This research focuses on local food products and the objective of this study is to identify the various types of local food selections in Kenya, additionally, assessing the factors that influence them. The research problem was to identify the measurements of the population’s growing interest in its products and determine whether it’s unpremeditated option, abetted by external stimuli or reasoned choice. The investigation was conducted on an exploratory study with twenty semi-structured interviews, and we used the quantitative research with 860 respondents. The individual motivations have a positive effect on reasoned choices; marketing stimuli, on the other hand, only have an effect on assisted and spontaneously option. Collective motivations have no effect on rational decision. Individual motivations trump reasoned choice, indicating that socially responsible consumption linked to well-being is the most developed.
