Poly I: C stimulates, Mx transcript and promotes an antiviral state in blood of Labeo catla (Hamilton 1822)

In the current investigation, the kinetics of Mx transcripts expression in the blood of Labeo catla (Hamilton 1822) inoculated with poly I: C, was studied for 14 days. The level of Mx transcript in the blood cells increased as compared to control fish inoculated with phosphate buffered saline. The level of Mx transcript was quantified along with semi-quantitative expression for β-actin. The level of Mx transcript was maximum on day 2 and 3 (β-actin: Mx ratio of about 0.8) which reduced after day 4 and the response disappeared on day 7. Western blots of the blood showed an immune-reactive band of 72 kDa, which is typical for L. catla Mx protein. Results suggest an increase in levels of Mx transcript after poly I: C injection which can stimulate an antiviral phase and the appropriateness of Mx expression investigation as an indicator to assess protective action.

The market value of equity of manufacturing companies during the COVID-19 pandemic

The market value of a public company reflects the expectations of investors. It is influenced by many factors, both internal and external to the company. This study aims to analyze whether intellectual capital moderates the effect of the debt-to-equity ratio and earnings per share on the market value of equity. A set of historical data was collected and analyzed based on a sample of 114 manufacturing companies listed on the Indonesia Stock Exchange from 2017 to 2019. This study uses moderated regression analysis to test proposed hypotheses and a robustness test to examine the sensitivity and consistency of the study results. The findings show that the debt to equity ratio affects the market value of equity, whilst earnings per share does not affect the market value of equity. The analysis also shows that intellectual capital could strengthen the effect of the debt to equity ratio on the market value of equity. In contrast, intellectual capital could not strengthen the effect of earnings per share on the market value of equity. AcknowledgmentsThe study was conducted with the support of the Universitas Riau, Indonesia.
On adaptive spatial-temporal processing for airborne surveillance radar systems

Implementing the optimum spatial-temporal (angle-Doppler) processor involves two crucial issues: the selection of processing configurations, and the development of adaptive algorithms which can efficiently approach the performance potential of the selected configuration. Among the three available configurations, the joint-domain, the cascade space-time, and the cascade time-space, this work shows that, in contrast to a popular belief, the detection performance potentials of both cascade configurations can fall far below that of the joint-domain optimum. In addition, this work presents a new adaptive algorithm, called the Joint-Domain Localized Generalized Likelihood Ratio detection (JDL-GLR), which is data efficient i.e., with fast convergence to the joint-domain optimum, as well as computationally efficient, together with such desirable features as the embedded constant false-alarm rate (CFAR) and robustness in non-Gaussian interference. >
Application of topology optimization technique in sand casting process of a complex product based on FDM 3D printing technology

Design optimization is one of the emerging CAE technologies thanks to the robust and strong structure of the computer and the ability to create complex designs using material additive technology. Recent modern innovations in 3D printing technology have made metal casting new breakthroughs. The demand of many products with complex shapes and geometries becomes very high. This makes the 3D printing more helpful and meaningful to contribute in the field of product design and development. This study presents an integrated framework for the implementation of complex 3D product design from fundamental technologies of CAD/CAE/AM (Computer Aided Design/Computer Aided Engineering/Additive manufacturing). Then, we apply casting technology to create models for products with complex shapes from FDM 3D printing technology. This integrated process is essential in assisting engineers to quickly design and create prototypes, and to fully control errors occurring during prototyping through CAD/CAE simulation to improve production efficiency of businesses and reduce time to bring products to customers. The experiment of sand casting based on the mold core from AM technology confirmed that the integrated approach is effective and applicable in the practice at manufacturing enterprises .

Model of Energy Savings achievable with Location- aware Node-to-Node Transmission in UbiComp Using Location Refresh Intervals.

A key area in MAUC is location tracking of nodes. Achievements in this area are commendable (1- 16). Researchers have also undertaken applying location- awareness to devise new functionalities and applications and also to improve ways of doing existing activities. Software engineering approaches into forming metrics and models in the field of MAUC are also gaining in value. Location-awareness remains a matter of resource consumption and support equipment available. It ends up having trade-offs between cost, amount of bandwidth consumed, performance, span of smallest unit of location and other factors. One overall effect is that location- tracking is done at varying refresh-intervals. This paper is a follow-up of a previous paper titled "Model of Energy Savings achievable with Location- aware Node-to-Node transmission in UbiComp"(18), in which one future work identified was to study effects of different location refresh intervals on percentage of energy savings achievable and models that can be formulated. The objective of this paper is to present the results of 24 different sets of experiments in the form of graphical displays and conclusions that can be drawn from them. abstract.
Beyond trust: Amplifying unheard voices on concerns about harm resulting from health data-sharing

Background: The point of care in many health systems is increasingly a point of health data generation, data which may be shared and used in a variety of ways by a range of different actors. Aim: We set out to gather data about the perspectives on health data-sharing of people living in North East England who have been underrepresented within other public engagement activities and who are marginalized in society. Methods: Multi-site ethnographic fieldwork was carried out in the Teesside region of England over a 6-month period in 2019 as part of a large-scale health data innovation program called Connected Health Cities. Organizations working with marginalized groups were contacted to recruit staff, volunteers, and beneficiaries for participation in qualitative research. The data gathered were analyzed thematically and vignettes constructed to illustrate findings. Results: Previous encounters with health and social care professionals and the broader socio-political contexts of people’s lives shape the perspectives of people from marginalized groups about sharing of data from their health records. While many would welcome improved care, the risks to people with socially produced vulnerabilities must be appreciated by those advocating systems that share data for personalized medicine or other forms of data-driven care. Conclusion: Forms of innovation in medicine which rely on greater data-sharing may present risks to groups and individuals with existing vulnerabilities, and advocates of these innovations should address the lack of trustworthiness of those receiving data before asking that people trust new systems to provide health benefits.
The strategic intersection of HR and CSR: CSR motive and millennial joining intention

The success and competitiveness of an organization recruiting the emerging workforce i.e., millennials can be ascribed in part to the organization's corporate social responsibility (CSR) engagement. This study explores the impact of organizational CSR on Nigerian millennials' joining intention through CSR motive perceptions: CSR-based organizational attractiveness (CSR-based OA) and perceived altruism (PA). To examine the empirical relationship among variables, data were obtained from respondents who were seeking employment or in-between jobs. Results revealed that CSR-based OA and PA significantly mediate the relationship between CSR and millennial joining intention. Findings present a unique perspective that significantly expands the literature. The implications of results are discussed and recommendations to managers are presented.

Integrated Model for the Stressors and Stresses of Construction Project Managers in Hong Kong

Construction projects involve multistakeholders e.g., architects, structural engineers, surveyors, contractors, suppliers, etc. completing a large number of unpredictable tasks in a complex process within a limited period of time. Construction project managers C-PMs are the key persons in achieving project success throughout the construction process, as they are responsible for planning the construction program, organizing human resources, controlling operations and the budget, and forecasting probable difficulties. Hence, C-PMs always encounter a great deal of stress in construction projects. Apart from the subjective feelings experienced by individual C-PMs, C-PMs may also feel objective stress due to the deviation between their actual abilities and their expected abilities on tasks or projects. To understand the integrated relationships between the various stressors and stresses of C-PMs, a survey was conducted of 108 C-PMs in Hong Kong. This paper attempts to investigate the causal relationships between stressors and stresses both subjective and objective. The study reveals seven stressors of C-PMs in the industry. Based on the results of a correlation coefficient, an optimized stressor-stress structural equation model is established. Four critical stressors were found to have significant impact on both the subjective and the objective stresses of C-PMs, including work overload, poor interpersonal relationships, poor work environment, and poor nonwork environment. A number of recommendations were made for both construction companies and individual C-PMs in their offices and at home in order to optimize their work performance in the real world.
Resveratrol prevents lipopolysaccharide-induced cognitive impairment in rats through regulation of hippocampal GluA1-containing AMPA receptors

Background: Evidence suggests that dysregulation in AMPA-type glutamate receptors (AMPA-Rs) has been associated with the pathogenesis of Alzheimer's disease (AD), especially during its early phase. Hence, the present study was performed to elucidate the impact of resveratrol (RV) on hippocampal expression of AMPA-Rs in a rat model of AD. Methods: A rat model of cognitive deficits was developed by a stereotactic intracerebroventricular infusion of lipopolysaccharide (LPS) in male Wistar rats (n=24). The LPS+RV30 group (n=12) received intraperitoneal injections of RV (30 mg/kg) at 30 min, 12 h, and 24 h before LPS injection. Meanwhile, the model (LPS) and sham (SO) groups only were treated with the vehicle solution (normal saline containing 1% ethanol). One day after the LPS infusion, the mRNA expressions of AMPA-Rs subunits (Gria1-4) were evaluated by RT–PCR. In addition, hippocampal levels of lipid peroxidation, superoxide dismutase, and nitric oxide were assessed. Seven days after the LPS challenge, the remaining animals (n=6 each group) were subjected to the Y-maze task, and the expression and localization of GluA1-containing AMPA-Rs in their hippocampi were investigated immunohistochemically. Results: Pretreatment with RV prevented LPS-induced cognitive dysfunction in rats and enhanced their working memory performance. Moreover, RV could moderately prevent oxidant-antioxidant imbalance in rats' hippocampi. RT-PCR results revealed that the hippocampal mRNA expression of the Gria1 was significantly reduced, while the expressions of Gria2 and Gria3 were increased in LPS-challenged rats. RV significantly modulated the alteration in the Gria1 mRNA expression; however, it could not influence the Gria2 and Gria3 mRNA expressions. The immunohistochemical assessment showed a significantly reduced immunoreactivity for GluA1-containing AMPA-Rs in all hippocampal subfields of the LPS group, and RV could effectively ameliorate the alteration. Conclusion: This study is the first to report that RV could modulate GluA1-containing AMPA-Rs dysregulation in a rat AD model.
Integral Abutment Bridges: Comparison of Current Practice Between European Countries and the United States of America

In the United States of America (USA), there are more than 9,000 Fully Integral Abutment Bridges and 4,000 Semi-Integral Abutment Bridges. Integral Abutment Bridges have proven themselves to be less expensive to construct, easier to maintain, and more economical to own over their life span. European experience with Integral Abutments is significantly less, but what experience has been gained has been positive. A European Survey was conducted to illustrate the design criteria used by each individual country for Integral Abutment Bridges. The survey requested information that would be useful to a designer when comparing the design requirements and restrictions of various European countries. As an added measure of comparison, these results were compared to some recently conducted surveys of state agencies within the USA. When looking at the results of the European Survey responses and past surveys of USA transportation agencies, it is clear that there are many similarities in design assumptions and construction practices. Yet, there are also significant differences between the various agencies. This paper attempts to highlight those similarities and differences.
The Use of Molasses as Additive with Different Ensiling Time and Physical Quality, pH and Nutritive of Value Maize Stover Silage

The objectives of this experimental research was to determine the effect of different ensiling time of maize stover silage with molasses as additive on physical quality, pH and nutritive value. The experiment used Factorial Randomized Completely Design (RCD) of two factors (maize stover = A and maize stover + 10% molasses = B), 3 ensiling time (0, 7, 14 days) and 4 replications. The treatments consisted of (A0 = maize stover without incubation, A1 = maize stover incubated for 7 days, A2 = maize stover incubated for 14 days) and (B0 = maize stover + 10% molasses without incubation, B1 = maize stover + 10 % molasses incubated for 7 days, and B2 = maize stover + 10 % molasses incubated for 14 days). The variable was measured physical quality, pH and nutritive value. The results showed that incubation time of A and B gave significant effect on physical quality and pH silage, maize stover silage without and with 10 % molasses incubated 14 days gave the best result of physical quality and pH (A = 4.00 and B = 3.89) silage. The result showed that incubation time of A and B gave highly significant effect (P<0.01) on Dry Matter (DM) and Ether Extract (EE), however it did not give significant effect (P>0.05) on Organic Matter (OM). It can be concluded that maize stover silage with 10% molasses incubated for 14 days could increase physical quality, decreased pH and maintain nutritive value.
Non‐Monotonic Floodplain Responses to Changes in Flooding Intensity

Overbank flooding is common along most rivers, and it influences the dispersal of sediment to floodplains. While variable discharge is a critical aspect of fluvial landscape evolution, it is typically modeled by simplifying the hydrograph to an equivalent steady discharge: the channel‐forming discharge. However, for all formulations used to simplify hydrographs, many different inputs can produce the same channel‐forming discharge. Here, we investigate how hydrographs with different flood intensities affect channel mobility, sediment accumulation patterns, and alluvial morphology using a suite of physical experiments where a fan delta grew by dispersing a cohesive sediment mixture into a basin. The experiments spanned three levels: no flooding, low‐intensity flooding, and high‐intensity flooding, while the time‐averaged water and sediment discharge was equivalent between all flooding regimes. Across this gradient, channel mobility, alluvial morphology and sediment dispersal scaled non‐monotonically with flooding intensity, and the data suggest that levee‐building feedbacks are the cause. We found that flood intensity modulates the relative balance between sediment delivery to channel margins, which nourishes levee growth, and the intensity of overbank flow, which inhibits levee growth. When flooding was absent, levees experienced consistent overbank flow and sediment delivery, leading to moderate levee aggradation and sporadic levee breaches. In contrast, when low‐intensity flooding was imposed, levees experienced enhanced sediment delivery by low‐amplitude floods, but only intermittent scouring. A further increase in flood intensity generated intense overbank flows that inhibited levee growth altogether. These results imply the existence of an optimum levee‐building condition, where flooding conditions stabilize channels through levee‐building feedbacks.
Trends in prevalence of low-birth-weight babies in India

Low birth weight (LBW) affects newborns’ survival and is a global concern especially for developing countries. It is the most common health indicator for assessing neonates’ health conditions. The present study was conducted to determine the prevalence of LBW in India in background of global perspective. A systemic review of the literatures was done, available in the principle medical databases including PubMed (including Medline), Google scholar, Web of science and Scopus from 2000 to 2021. A total of 65 articles were identified in the described database. Altogether 24 articles met the inclusion criteria and were eligible for data analysis. According to the all four national family health survey (NFHS) a decreasing trend is observed in the prevalence of LBW. The prevalence of LBW in India is 16.4 % in NFHS-4, 20.9% in NHFS-3, 22.9% in NFHS-2 and 25.2% in NHFS-4 respectively. A number of socio-demographic and maternal factors are responsible for LBW babies in India. LBW babies are global public health concern. Special emphasis should be given to the underlying factors responsible for LBW babies in India.
