Effect on superoxide dismuatse activity in earthworm Eisenia fetida on direct exposure to neonicotinoid insecticide imidacloprid

Imidacloprid is a systemic insecticide that acts as an insect neurotoxin and belongs to class of chemicals called the neonicotinoides which act on central nervous system of insects. Three concentration of imidacloprid (0.134 μl, 0.195 μl and 0.285 μl) have been used during the experiment for evaluation of enzymatic activity. The increase in superoxide dismutase (SOD) activity suggests that SOD has the capacity to scavenge reactive oxygen species (ROS) under the stress at lower concentration of imidacloprid and it also indicated that the activity of the superoxide dismutase had shown different responses to toxicity of various concentrations of imidacloprid for different exposure periods in earthworm Eisenia fetida. Imidacloprid at concentrations of 0.195 μl and 0.285μl had shown the SOD activities of 6.773 and 7.263 U/mg protein respectively at 48 hr of exposure, while a concentration of 0.285μl has showed an enzyme activity of 6.835 U/mg protein at 24 hr of exposure. The study revealed that the activity of antioxidant enzyme of earthworms is altered due to stress produced by neonicotinoid insecticide. The statistical data of pesticide is highly significant with respect to treatment and time of exposure.
A DC to 25 GHz 6‐bit digital attenuator based on 0.18 μm SiGe BiCMOS technology

A wideband, low phase variation 6‐bit digital step attenuator (DSA) is presented. To further expand the operation bandwidth while keeping low attenuation and phase error, modified π/T‐type attenuator structures are introduced. In the large attenuation unit, the modified π‐type attenuator structure is adopted, which includes middle adjusting capacitance and bypass compensating capacitance. Moreover, the reduced T‐type structure with bypass compensation capacitance is used in the small attenuation units. The influence of the introduced capacitance on various attenuation units is analyzed. To prove the effectiveness of the modified structure on extending the bandwidth, a DSA with a broad bandwidth of DC‐25 GHz and low attenuation and phase error is realized in a 0.18 μm SiGe BiCMOS technology. The attenuation range of the attenuator is 31.5 dB with 0.5‐dB step, which is controlled by 6 bits digital input. Its root‐mean‐square (RMS) attenuation error is lower than 0.3 dB, and the phase error (RMS) is below 4.9°. The insertion loss is lower than 11 dB, and the core area is 0.33 mm2.

Uncovering the Providers’ Continuance Intention of Participation in the Sharing Economy: A Moderated Mediation Model

The sharing economy has evolved into a promising business concept that enables individuals to share their idle resources, improving resource utilization efficiency commercially. Recently, it has gained enormous academic attention. However, little concern has been given to the behavior of individual providers on the supply side. This paper aims to uncover the motivational and trust-based providers’ continuance intention of participation in the context of peer-to-peer ride-sharing services. Based on the survey data from 202 providers and the partial least-square analysis, we confirm the mediating effect of attitude in the relationships between participation continuance intention; trust; and three motivational dimensions: economic benefits, social–hedonic value, and sustainability. We further confirm the moderating effects of innovativeness using PROCESS. The results show that economic benefits, social–hedonic value, and sustainability significantly affect providers’ participation continuance intention. Moreover, attitudes toward the sharing economy play a complementary partial-mediating role in the relationships from economic benefits and social–hedonic value to participation continuance intention, which is negatively moderated by innovativeness. Trust does not significantly affect providers’ attitude toward the sharing economy and participation continuance intention in the peer-to-peer ride-sharing context.
Effect of zinc(II) additive on the ammonia loss and CO2 absorption in ammonia-based CO2 capture process

Carbon dioxide capture processes using aqueous ammonia solution provide many advantages over amine based processes, including a high CO2 absorption capacity, a low regeneration energy and no degradation of solvent. However the industrial application of ammonia-based CO2 capture technology is limited by the high ammonia volatilization and loss. In this study, the additive Zinc(II) was introduced into ammonia solution for ammonia suppression due to the complexation capability with free NH3. The effect of Zn(II) concentration, ammonia concentration and CO2 loading were investigated using wetted wall column. It is observed that the addition of Zn(II) can significantly reduce NH3ammonia loss while slightly decrease CO2 absorption rate. This study can provide a novel approach of NH3 suppression in ammonia-based CO2 capture process, which also holds a promising industrial application. Further study should be carried out to optimize the process.
Characteristic Band Selection of Near-infrared Spectrum for Determining Peroxide Value of Oil Based on iPLS

During analyzing peroxide value of soybean oil by near-infrared spectroscopy,iPLS(interval partial least squares) was applied to select characteristic spectral bands of soybean oil.The whole spectrum was divided into several smaller bands using data intervals of 10 and 20 points,respectively.Then,PLS regression models were established by using whole spectrum and smaller bands.These models were evaluated by PRESS(predicted residual sum of squares). The results indicated that after selecting characteristic bands,the R2,RMSEP and RSD were 0.9791,0.0513 and 2.12%,respectively.The variables in these models were decreased effectively and the prediction accuracy was improved.

An Area-Efficient Low Quiescent Current Output Capacitor-Less LDO with Fast Transient Response

A Power-area-efficient output-capacitorless low- dropout (OCL-LDO) regulator with fast transient response is presented in this paper. The proposed technique permits the regulator to achieve small undershoot (overshoot) when the load steps up (down) and consumes little extra power. The proposed LDO regulator has been implemented and fabricated in a 0.18- μm CMOS process. It occupies an active area of0.0071mm2. The simulated results have shown that the proposed circuit consumes a quiescent current of 0.7 μΑ at no load, regulating the output at 0.7 V from a voltage supply of 0.9 V. The simulated transient output voltage is 47 mV when load current is stepped from 1 mA to 20 mA in 400 ns with Cl =3D10 pF. Meanwhile, this circuit shows a good of flgure-of-merit (FOM).
Understandings of Social Innovation within the Danish Public Sector: A Literature Review

Social innovation is an emerging theme within innovation theory, and so is the concept of public service innovation networks for social innovation (PSINSIs). The purpose of this article is to explore how social innovation in Danish public services is conceptualised and enacted through the lenses of public service innovation networks for social innovation. To do this, a thorough integrative review of the literature dealing with the Danish context is conducted. The Danish context is interesting in order to investigate these network arrangements, firstly because they are not well understood in the context of the Nordic welfare states, which Denmark is part of, and then because municipalities and civil society have historically had a mutually dependent relationship in Denmark. The article highlights that social innovation is framed in several ways in the Danish public sector. In particular, the results show that the literature can be grouped according to four themes: (1) samskabelse (co-creation), (2) collaboration with civil society, (3) social entrepreneurs and social innovation and (4) public–private innovation partnerships. Moreover, the article presents and discusses a number of Danish empirical projects that may be understood through the lens of the PSINSI framework. Hence, the paper contributes with new theoretical perspectives, in addition to contributing to practice.
Mitigating distributed denial of service attack: Blockchain and software‐defined networking based approach, network model with future research challenges

With the rise of technology and easy access to the internet, it is nowadays very easy to perform distributed denial of service (DDoS) attacks. The main target of a DDoS attack is to suspend or interrupt any available services online. It can be done for personal profits or professional reasons, and sometimes over political reasons too. Some of the recent attacks are as follows: the largest ever recorded packet per second based DDoS attack on Akamai servers, the attack on Amazon, and the attacks on the website of the US Department of Health and Human Services. Cutting‐edge technology like Blockchain and software‐defined networking (SDN) are very helpful in developing a mitigating architecture with their collaborative approach, where SDN can authenticate the legitimate IP address and Blockchain can help to store the legitimate user in the trust list with a complex architecture of different assistant Blockchain. This paper proposes three different network architectures for the protection of DDOS attack by enabling Blockchain technology with SDN concept.
A simulation‐based analysis for the performance of thermal solar energy for pyrolysis applications

Solid plastic waste presents a perplexing waste disposal challenge, which has increased in importance due to increasing demand for plastic products over the last century. Chemical recycling approaches such as pyrolysis, allow the conversion of the polymer waste into value‐added fuels and chemicals. Pyrolysis provides potential pathways for the circular economy of plastics, especially because of the potential to produce feedstock chemicals for remanufacturing of new plastic products. The high temperatures required to operate the pyrolysis process, however, affect its environmental performance due to the indirect emissions generated when supplying the process with energy. This drawback can be overcome by using renewable energy sources. This work investigates the integration of concentrated solar power (CSP) with the pyrolysis of high‐density polyethylene (HDPE), to evaluate the process environmental performance. A mechanistic model is used to describe the pyrolysis reaction kinetics, and is integrated into an Aspen Plus flowsheet model to describe the entire pyrolysis process. System Advisor Model was used to model the solar‐thermal process system, which supplies the process with the required heat throughout the year. Process simulations show that operating the pyrolysis reactor at 520°C would convert 78%wt of HDPE to light gases and liquid fuels. The process requires 752 kWhth/ton‐HDPE, out of which 82% is used to heat the feed and operate the distillation column. Model simulations showed drastic reductions in fossil fuel usage, with solar energy capacity providing 52.5% of the pyrolysis process annual heat demand. Model‐based optimization analysis showed that 72.6% of the pyrolysis plant thermal requirements could be generated via solar energy during the summer, with a CO2 avoidance potential of about 67 kg/ton‐HDPE.
Docking, Synthesis and Anticancer Activity of Some Newer Carbazole Derivatives

Numerous carbazole derivatives were designed by the Chemsketch software followed by 3D optimization. Docking studies were performed using AUTODOCK 4.2. 6 software to check their binding interactions with eukaryotic topoisomerase-I, based on the crystal structure of Human Topoisomerse-I-DNAcomplex (PDB ID: 1A35). Results of docking studies of designed carbazole derivatives were compared on the basis of their minimum binding energy with a well known topoisomerase-I inhibitor i.e. Rebeccamycin,. Above results were used to find out active compounds and two series of such active compounds i.e. 2-[(4, 5-dihydro-2-substitutedphenyl)imidazol-1-ylamino]-1-(9H-carbazol-9-yl)ethanone (3a-3e) and 2-(9H-carbazol-9-yl)-N'-[{(4-substitutedphenyl)(piperazin-1-yl)}methyl]acetohydrazide (3a-3e) were synthesized. All the synthesized compounds were characterized by IR, 1H NMR, 13C NMR, MASS spectrometry and elemental analysis and also screened for their invitro anticancer activity against human breast cancer cell line (MCF 7) by sulphorodamine B (SRB) assay method. GI50 was measured by using 10, 20, 40 and 80 g/ml concentrations of tested compounds along with the standard i.e. Rebeccamycin. Results revealed that the tested compounds 3c, 3e, and 3a were comparable to Adriamycin having GI50<10g/ml. Compound 3c and 3a were found to be most active among all the tested compounds.
Adaptive multiple access assists multiple users over multiple‐input‐multiple‐output non‐orthogonal multiple access wireless networks

The works in this study examine three scenarios. The scenario (I) as a common scenario with the base station (BS) and users are equipped with multiple antennae over Nakagami‐m fading channels. To improve system performance, the transmit antenna selection (TAS) and maximization of successive interference cancellation (max‐SIC) framework are deployed. A novel cumulative distribute function (CDF) for the scenario (I) is proposed, and the outage probability (OP) in novel closed form can be obtained. It is challenging due to scenario (I) consists of massive users equipped with multiple antennae over Nakagami‐m fading channels. Therefore, this study proposes scenario (II) with a maximum of SIC and minimum of instantaneous bit rate (max‐SIC‐min‐rate) framework for aiding multiple access to reduce the algorithm complexity of the scenario (I). Some adaptive multiple access strategies are proposed as adaptive PA factors, adaptive min–max bit rate threshold, and adaptive Nakagami‐m coefficient are proposed. Finally, the scenario (III) is examined by also applying the max‐SIC‐min‐rate framework as the scenario (II), however, comparing to the adaptive min–max bit rate threshold to investigate the OP, system throughput, and energy‐efficient (EE) performances. The obtained results as shown in the numerical results section confirm that, on one hand, the system performance of the scenario (II) is approximate or better than the scenario (I) at the same transmit power; on another hand, the scenario (III) reaches the system throughput and EE performances better than the other scenarios at the high transmit power. The analysis results are proved and verified by Monte Carlo simulation results.
Genetic variability in Tambaqui generations of the breeding program in the Central-West Region of Brazil

The implementation of fish breeding programs in Brazil has brought significant results in the productivity of tilapia. However, the insertion of native species with great potential (such as Tambaqui Colossoma macropomum) in these programs is still recent, and thus requires genetic information for monitoring and enabling their consolidation into the programs. The objective of the present study was to evaluate the genetic diversity of the parental generation (G0) and two consecutive generations (G1 and G2) in the C. macropomum genetic improvement program, located in the municipality of Sorriso, Mato Grosso, Brazil. Ninety caudal fin samples were collected (30 samples per generation) for DNA extraction. The genetic study implemented seven microsatellite markers (Cm1A8, Cm1A11, Cm1D1, Cm1E3, Cm1F4, Cm1F5, and Cm1H8). A total of 17 alleles were amplified, with variations in the mean number between four to two alleles per locus. The size per locus ranged from 170 to 360 bp. The average inbreeding coefficient was 0.126 (G0), -0.040 (G1), and 0.131 (G2). No null or exclusive alleles were found. The observed heterozygosity values for G1 and G2 demonstrated the preservation of genetic variability (0.453 and 0.409, respectively). In conclusion, the genetic diversity of the parental generation (G0) and the two progenies generations (G1 and G2) were adequate, which demonstrates that the genetic improvement program was conducted correctly; however, it is important to continue to evaluations the genetic diversity of the future progeny.
Digital Twin Providing New Opportunities for Value Co-Creation through Supporting Decision-Making

The application of digital twins provides value creation within the fields of operations and service management; existing research around decision-making and value co-creation is limited at this point. Prior studies have provided insights into the benefits of digital twins that combined both data and simulation approaches; however, there remains a managerial gap. The purpose of this paper is to explore this research gap using input from a multiple case study research design from both manufacturing environments and non-manufacturing environments. The authors use ten cases to explore how digital twins support value co-creation through decision-making. The authors were all involved in the development of the ten cases. Individual biases were removed by using the literature to provide the assessment dimensions and allowing a convergence of the results. Drawing on the lessons from the ten cases, this study empirically identified eight managerial issues that need to be considered when developing digital twins to support multi-stakeholder decision-making that leads to value co-creation. The application of digital twins in value co-creation and decision-making is a topic that has developed from practice and is an area where a research gap exists between theory and practice. A cross-case analysis was developed based on the literature and the ten cases (eight industrial and two pilot-scale cases) providing the empirical findings. The findings describe how firms can design, develop, and commercialize digital-twin-enabled value propositions and will initiate future research.
Authentic Leadership Education: An empirical discussion from Pakistani higher education

The authentic style encourages leaders to be mindful of their strengths, weaknesses, and emotions, using practical methods for improving their leadership abilities. Identifying an authentic leader is a description of those who have positive beliefs, lead from the heart, set the highest standards of ethics and morality, and go beyond their interests for their followers' well-being. It is critical to understand where one stands on important moral and professional issues to become an authentic leader and then act on that knowledge. Authentic leaders, although specific characteristics, such as positive psychology, self-awareness, morals and ethics, and a person, transparency, and balanced processing; this study explores authentic leadership strengths and weakness empirically. The link between theory and practice applied settings and helps practitioners add value to professional growth has been discussed. The study also shed light on the importance of workforce development action plans, but the ties outlined herein show that casual relations and additional tests would help confirm the connections.
A Simulation of Salt Transport in NaCl-Laden Soil Barrier to Control Subterranean Termites in an Earth Embankment

Subterranean termite activity can increase the hydraulic conductivity and water infiltration of filling soil, and therefore affects the stability of an earth embankment and subsequent safety. As a physical barrier for sustainable termite management, NaCl-laden soil barrier (NLSB) is a promising alternative for subterranean termite control in earth embankments. This novel technology can prevent tunneling and penetration of subterranean termites into the interior of an embankment and has been widely employed for more than 20 years in Zhejiang Province, China. The efficacy and longevity of NLSB depend on the long-term presence of NaCl concentration in soil barriers. The aim of this study is to develop an understanding of water flow and salt transport in NLSB based on the two-dimensional Richards’ equation and convection dispersion equation using the HYDRUS software package. Conceptual and numerical models of NLSB are modeled using scenario analysis according to water level fluctuations, saturated hydraulic conductivity, and rainfall infiltration conditions. Furthermore, the center and spread variance of a solute mass over a 100-year period are quantified using moment analysis. As flood frequency, saturated hydraulic conductivity, and rainfall infiltration flux increase, salt desalination in NLSB significantly increases. When the rainfall infiltration flux is 1% of the annual average rainfall, the total amount of salt transport and leaching can increase by 55%. Moreover, these results facilitate better long-term sustainable management of existing sites and optimal design of future NLSBs.

Education, smoking and health: evidence from Canada

ABSTRACT The present paper assesses the causal effects of education on smoking and self-rated health in Canada. Education is instrumented using the changes in compulsory schooling laws. The sample is restricted to cohorts born between 1946 and 1964. The data are from the Canadian General Social Surveys of 1995 and 2016, allowing to observe the evolution of the gradient over the life course. The gradient is confirmed for smoking and self-rated health in correlational estimations, with stronger associations among males in later life. However, the IV regressions produce no evidence for a causal relationship.
