Characterisation of fatty acid profiles of Tenebrio molitor larvae reared on diets enriched with edible oils

Several species of insects have been indicated as suitable and alternative sources of nutrients for humans and animals. A crucial aspect is that their nutritional composition and development time can be influenced by the substrate used for rearing. The main objective of this study is to evaluate how the fatty acid composition of Tenebrio molitor (Coleoptera: Tenebrionidae) larvae changes with different rearing substrates. For this purpose, a standard diet (51.8% wheat bran + 40.7% soybean meal) was alternatively supplemented with addition of 7.5% (w/w) sunflower, linseed or fish oil. Dry matter, percentage of proteins and lipids, ash and fibre of larvae and substrates, as well as insect development time were determined, highlighting slower growth for insects raised on oil-enriched diets, compared to the control. Gas-chromatography was used to evaluate the fatty acid profile of larvae and substrates. A total of 15 fatty acids was identified and quantified. Palmitic, oleic and linoleic acids were always the most abundant fatty acids detected in larvae, suggesting the presence of physiological regulation mechanisms in T. molitor. The larval content of palmitoleic, oleic, alpha-linolenic and eicosapentaenoic acids was correlated with their content in the rearing diets, indicating strict dependence on diet mainly for PUFA n-3. The n-6/n-3 ratio was influenced by the substrate as well, showing a similar trend between insects and diets but with less variability in larvae. Principal component analysis conducted on the fatty acids profile of larvae displayed several clusters based on the different growing media. This study highlights the importance of the diet in determining the final fatty acid profile of mealworm larvae, although fatty acid enrichment could be dampened by physiological processes of the insects.
A Parameter Compensation Method for the Kinematics Calibration of a 7-DOF Manipulator Using Laser Tracker

The link parameters of a manipulator are the most important factors affecting its absolute positioning accuracy. Due to the redundancy of the 7 degrees-of-freedom (DOF) manipulator, there are multiple sets of inverse kinematics solutions for the manipulator, which increases the difficulty in the calibration process. This paper proposed a parameter compensation method to calibrate the Denavit-Hartenberg (DH) parameters of a 7-DOF manipulator. By analyzing the geometry structure of the manipulator, some redundant parameters could be removed to guarantee the convergence of the calibration. Before calibration, the mean and root-mean-square (RMS) position errors of the 7-DOF manipulator were 2.9402 mm and 3.3644 mm, and the mean and RMS orientation errors were 0.0082° and 0.0091°, respectively. After calibration, the mean and RMS position errors were reduced to 0.2166 mm and 0.2559 mm, and the mean and RMS orientation errors were reduced to 0.0012° and 0.0014°, respectively. It was demonstrated that the proposed parameter compensation method was effective in the kinematics calibration of the 7-DOF manipulator.
Robust Lyapunov-based motion control of a redundant upper limb cable-driven rehabilitation robot

Abstract This research presents an upper limb cable-driven rehabilitating robot with one degree of redundancy to improve the movements of the injured. A spatial trajectory is planned through the joint limit avoidance approach to apply the limits of the joint angles, which is a new method for trajectory planning of joints with an allowed definite interval. Firstly, a Lyapunov-based control is applied to the robot with taking uncertainty and disturbances into consideration. To derive the best responses of the system with considering uncertainty and disturbances, a novel robust tracking controller, namely a computed-torque-like with independent-joint compensation, is introduced. The mentioned new robust controller has not been applied to any cable robot which is the novelty of this paper to derive a superior output and the robustness of the given approach. Stability analysis of both controllers is demonstrated and the outputs of the controllers are compared for an exact three-dimensional motion planning and desirable cable forces. Eventually, the proposed novel controller revealed a better function in the presence of uncertainties and disturbances with about 28.21% improvement in tracking errors and 69.22% improvement in the required cable forces as control inputs, which is a considerable figure.
Open-circuit fault resilient ability multi level inverter with reduced switch count for off grid applications

In a multi-level inverter (MLI), the switching component number effect on volume and reliability is a major concern in on-grid and off-grid applications. The recent trend in MLI, reduced component number of power switches, and capacitors in multi-level inverter topologies have been driven for power conversion. The concept of fault tolerance is not considered in many such configurations; due to this the reliability of the MLI is very low. So now it is a major research concern, to develop a strong fault resilient ability power electronic converter. In this work, a novel configuration of a multilevel inverter with a lower switch count is proposed and analyzed with fault tolerance operation for improvement of reliability. Generally, the fault-tolerant operation is analyzed in only any one of the switches in MLI. But the proposed topology is concerned with multiple switch fault tolerance. Further, the phase disposition pulse width modulation (PDPWM) control scheme is utilized for the operation of the proposed inverter topology. The proposed inverter topology is simulated in MATLAB/Simulink environment under normal and faulty condition; the results are obtained and validated.
Pesticides Xenobiotics in Soil Ecosystem and Their Remediation Approaches

Globally, the rapid rise in the human population has increased the crop production, resulting in increased pesticide xenobiotics. Despite the fact that pesticide xenobiotics toxify the soil environment and ecosystem, synthetic pesticides have increased agricultural yields and reduced disease vectors. Pesticide use has increased, resulting in an increase in environmental pollution. Various methods of controlling and eliminating these contaminants have been proposed to address this issue. Pesticide impurity in the climate presents a genuine danger to individuals and other oceanic and earthly life. If not controlled, the pollution can prompt difficult issues for the climate. Some viable and cost-effective alternative approaches are needed to maintain this emission level at a low level. Phytoremediation and microbial remediation are effective methods for removing acaricide scrapings from the atmosphere using plants and organisms. This review gives an overview of different types of xenobiotics, how they get into the environment, and how the remediation of pesticides has progressed. It focuses on simple procedures that can be used in many countries. In addition, we have talked about the benefits and drawbacks of natural remediation methods.

Material and Methods: A cross-sectional questionnaire study was conducted using a validated questionnaire, Dental Undergraduates Preparedness Assessment Scale (DU-PAS) and no samplings were involved. The questionnaire was distributed via University presentative of each university from MDSA in the form of online and written questionnaire. The data were analysed using SPSS version 23. Results: 239 students responded to this study. Responses revealed that student felt adequately prepared to carry out simple clinical procedures such as taking consent (88.3%), tooth-coloured fillings (87.4%), non-surgical periodontal treatment (86.6%), do proper history taking (85.8%), bitewing radiograph (84.1%) and communication skills (69.9%). However, low levels of scores were reported on ability to do an amalgam restoration (12.1%), endodontics treatment especially multi-rooted tooth (9.6%), crowns (9.2%), referral for suspected oral cancer (31.8%), research skills (15.1%) and raising concerns regarding inappropriate behaviour of colleagues (7.9%). There was significant difference between the level of preparedness of final undergraduate student in public and private universities. Conclusions: This is the first study of self-perceived preparedness of final year undergraduate students in Malaysia. The results showed that the self-perceived preparedness of final year student was satisfactory for a range of clinical and effective skills. However, several areas of weaknesses were identified which underscore the need for additional training and consolidation.
Modeling and evaluating the impact of denial-of-service attacks in emerging wireless and mobile applications

The proliferation of wireless networks has brought significant change to people’s daily life, such as WiFi and cellular networks. It further introduces new applications and services, including smart grid systems and emerging mobile services. However, due to the shared nature of wireless channels, these emerging applications are vulnerable to denial-of-service attacks, which come with various intents, from selfish sharing of channel resources to disrupting the communication among other users. A direct consequence of such attacks is performance degradation or even denial-of-service in the network. Moreover, they can lead to potentially devastating system failures, such as in the smart grid where physical control is all based on successful message delivery in the network. As a result, it is critical to understand the impact of denial-of-service attacks in emerging wireless applications. In this dissertation, we aim at understanding the impact of denial-of-service attacks against emerging wireless applications. Because it is not practical to provide a unified framework to study denial-of-service attacks in all applications with distinct objectives and requirements, we adopt an application-specific methodology to model and evaluate denial-of-service attacks. We focus on three emerging applications: multi-modal CSMA/CA networks, time-critical networks for the smart grid, and smart phone applications. In particular, we first study the multi-modal CSMA/CA networks that provide configurable MAC-layer parameters for wireless nodes to support multiple modality. Such configurability, however, induces a selfish behavior: a node deliberately reduces its MAC-layer backoff time to gain unfair access to the channel, which is called backoff misbehavior. We define a new performance metric to quantify the benefits of backoff misbehavior and show the impacts of a wide range of backoff misbehaving nodes on the network performance. Second, we study jamming attacks that can cause severe network problems by broadcasting radio interference in time-critical wireless networks for the smart grid. We analyze the jamming impact on time-critical message delivery, and implement a detector to accurately identify attacks. In addition, we propose a scheme to minimize the delay of time-critical message delivery under jamming attacks in smart grid applications. Finally, we investigate the propagation and impact of a mobile botnet, a collection of compromised smart phones able to perform coordinated attacks against mobile network infrastructures. The work in this dissertation advances our understanding of network vulnerabilities associated with emerging wireless networks, and offers instrumental guidance into the security design for future wireless and mobile applications.
Additional Effects on High-Speed Railway Subgrade Caused by Newly-Built Flyover and Treatment Techniques

With 3Dfinite difference numerical simulation method,this paper analyzes the additional effects(the additional settlement and additional horizontal displacement)on the existing high-speed railway subgrade generated by the newly-built highway flyover.It also studies the treatment techniques taken for restraining these additional effects as well as the dominant factors for the additional effects.Results show that the additional settlement obtained by numerical simulation agrees well with those calculated by the theoretical formula of 0.025method used for determining the depth of compressed layer.Bridge foundation load makes the horizontal displacement in the shallow layer of foundation under subgrade tend to the pier while far from the pier in the deep layer of foundation.The depth of foundation treatment should be greater than the neutral of additional horizontal displacement.Small diameter steel pipe row piles and pile top connection beams are adopted for isolation treatment at the proper position between pier and subgrade.When the row number of piles exceeds 3or the treatment length is more than 60m,it has little use in controlling the additional effect of railway subgrade.However,increased pile length can effectively reduce the additional effects on railway subgrade.
Can We Teach Environmental Education in English Courses?

The preparation of teaching and learning resources in environment education (EE) is important because it supports the attainment of the goals of RA 9512 and addresses the lack of teaching and learning resources in EE (Kimaryo, 2011). Using mixed methods of research, the study aimed to review the English Education curriculum to identify entry points of EE integration using the Department of Environmental and Natural Resources (DENR) EE materials, and to develop and to validate exemplar session plans with EE integration in different English Education courses. Data were gathered using documentary analysis, assessment of the DENR EE materials, and assessment of the proposed session plans using rubric. Results show that the entry points for EE integration is adequate, and that the DENR EE materials are found to be appropriate, relevant, and highly flexible as instructional materials for EE integration in English courses. EE can be integrated in the different parts of the lesson such as the motivation, lesson proper and assessment. The proposed session plans were rated excellent by the jurors, and therefore serve as acceptable and relevant materials for the mainstreaming of EE in the English Education curriculum. Wide dissemination and pilot-testing of the session plans integrating EE are recommended.
Hydro-chemical evaluation and fluoride health risk assessment in school children of plain tropical Central India

Abstract The present study makes an attempt to mainly design to analyze the impact of fluoride in plain tropical central India and affecting health conditions of the school children. Fluoride naturally, a toxic material for the human beings but its more concentration in the body due to anthropogenic activities increases the risk of more dangerous outcomes. We utilized ionic concentration, hydrochemistry, fluoride content and health risk assessed from the different collected water samples in the month of June, 2017. This study shows the concentration of fluoride content in water sample ranged from 0.08-2.4 mg/l (mean = 0.6 mg/l) and had positive relation with the pH (r = 0.49), HCO3 - (r = 0.29) and Na+ (r = 0.20). Few, 9.18% water sample out of total collected samples were exceeding the permissible limit (> 1.5 mg/l) of fluoride content in groundwater which was not suitable for drinking purpose due to the heavy loading of fluoride content.
Weighted factor multi-objective design optimisation of a reluctance synchronous machine

The relationship between the well known competitive torque density and less competitive power factor of reluctance synchronous machines is investigated. The study consists of a multi-objective design optimisation implementing a weighted factor optimisation technique. The investigation was carried out by implementing a complete machine model in the optimisation, with varying machine pole number and flux barrier number combinations. Determination of the weighting of this specific parameter relationship enables the designer to select an optimum multi-objective relationship during optimisation. A specific machine was selected for analysis, then analysed and manufactured for validation of simulation results.
‘Shall We Send a Panda?’ A Practical Guide to Engaging Schools in Research: Learning from Large-Scale Mental Health Intervention Trials

The substantial time that children and young people spend in schools makes them important sites to trial and embed prevention and early intervention programmes. However, schools are complex settings, and it can be difficult to maintain school engagement in research trials; many projects experience high levels of attrition. This commentary presents learning from two large-scale, mixed-methods mental health intervention trials in English schools. The paper explores the barriers and challenges to engaging schools in promotion or early intervention research and offers detailed recommendations for other researchers.
The Effect of Corn Dextrin on the Rheological, Tribological, and Aroma Release Properties of a Reduced-Fat Model of Processed Cheese Spread

Low-calorie and low-fat foods have been introduced to the market to fight the increasing incidence of overweightness and obesity. New approaches and high-quality fat replacers may overcome the poor organoleptic properties of such products. A model of processed cheese spread (PCS) was produced as a full-fat version and with three levels of fat reduction (30%, 50%, and 70%). Fat was replaced by water or by corn dextrin (CD), a dietary fiber. Additionally, in the 50% reduced-fat spreads, fat was replaced by various ratios of CD and lactose (100:0, 75:25, 50:50, 25:75, and 0:100). The effect of each formulation was determined by measuring the textural (firmness, stickiness, and spreadability), rheological (flow behavior and oscillating rheology), tribological, and microstructural (cryo-SEM) properties of the samples, as well as the dynamic aroma release of six aroma compounds typically found in cheese. Winter’s critical gel theory was a good approach to characterizing PCS with less instrumental effort and costs: the gel strength and interaction factors correlated very well with the spreadability and lubrication properties of the spreads. CD and fat exhibited similar interaction capacities with the aroma compounds, resulting in a similar release pattern. Overall, the properties of the sample with 50% fat replaced by CD were most similar to those of the full-fat sample. Thus, CD is a promising fat replacer in PCS and, most likely, in other dairy-based emulsions.
Adjuncts and multimodal analgesia: a narrative review

Background and Objective: Multimodal analgesia is recommended for pain management following major surgery. This method uses different analgesic agents, which may target different components of pain transmission, with the aim of improving post operative analgesia and decreasing reliance on opiate-based medications. This, in turn, aims to reduce the side-effects secondary to opiate use thus improving post operative recovery. It forms part of a successful enhanced recovery after surgery program and includes the combined use of neuraxial blockade, regional anaesthesia and systemic medications. This article aims to review the main adjuncts used as part of a multimodal analgesia strategy in an enhanced recovery after surgery program and evaluate their evidence base. Methods: A literature search was performed using PubMed. The terms multimodal analgesia, adjuncts, surgery, and enhanced recovery were included. Only papers published in English after 2003 were reviewed. Key Content and Findings: Our review covers contemporary evidence around the use of analgesic adjuncts including their associated risks and benefits in anaesthetic practice as part of an enhanced recovery after surgery programme. Conclusions: A range of adjuncts have been studied to investigate whether their use as part of a multimodal analgesia plan improves post operative pain alongside other outcomes. It is recommended that all patients should receive paracetamol and a non-steroidal anti-inflammatory medication in the absence of contraindications. Ketamine and magnesium have evidence of benefit when used perioperatively. Clonidine and dexmedetomidine, both alpha-2-agonists, improve acute pain with opioid sparing properties. Glucocorticoids, which are commonly used for their antiemetic properties, may have additional analgesic benefits. The risks and benefits need to be carefully evaluated before considering using intravenous lidocaine due to its narrow therapeutic window. The evidence for benefit from perioperative use of gabapentinoids is inconclusive. Other medications which may have the potential to be used as adjuncts to multimodal analgesia show some promise. This will be an area for future research and includes the use of duloxetine, a selective-serotonin reuptake inhibitor.
Feasibility Study of Practical AoA Estimation Using Compressed CSI on Commercial WLAN Devices

Wireless local area network (WLAN)-based localization is key for advanced indoor Internet-of-Things and embedded sensor applications. To further improve the accuracy of indoor localization, attention has been focused on WLAN-based indoor localization using channel-state information (CSI) in addition to the existing information provided by received signal strength (RSS). For easy and low cost installation of wireless sensing, wireless sensing based on standardized protocols and commercial WLAN devices, such as IEEE 802.11ac and IEEE 802.11ax, is necessary. Much previous research used the angle of arrival (AoA), but commercial WLAN devices cannot use directly for AoA estimation. Therefore, we propose a practical method for estimating the AoA to solve four problems: 1) compressed CSI, which cannot be used for AoA estimation directly, 2) the antenna wireline, in which the phase changes depending on the length of the wireline, 3) the antenna spacing, in which the distance between antennas places a restriction on AoA estimation, and 4) antenna individuality, in which the antennas used in actual MIMO communication have different characteristics. We implemented the proposed method on IEEE 802.11ac devices and evaluated it in a lecture room and shield tent. The results indicate that the proposed method can estimate AoA with an average error of 9.1° and reduce the estimation error by 85.4 % compared with a straightforward approach.
Digital Performance in EU Member States in the Context of the Transition to a Climate Neutral Economy

The climate-neutral economy is today, more than ever, the priority issue for all governmental and non-governmental bodies, directly and indirectly involved in the ambitious and responsible process of society’s transition to the green economy. To be or not to be sustainable today is no longer an option, but an urgent necessity. Based on these considerations, our research aims to add to the knowledge on the digital performance of the Member States in the context of the transition to a climate neutral economy, by analyzing the mutations that have occurred in the digital performance of the EU countries in the period 2015–2020, as well as forecasting developments for the year 2025. In order to obtain a relevant result, we used the components of the DESI index, published by the European Commission, and the variables were processed through hierarchical cluster analysis. The results demonstrate that, around the core formed in 2015 by four high digitally performing countries from the North of Europe in 2015, other countries have gradually clustered, so that in 2025 we estimate that a number of eight Member States will be part of the group of the most digitally performing countries. These countries are decisively committed to the transition towards a climate-neutral economy, their initiatives and examples of good practice can be taken up by all European and non-European countries pursuing the same objectives of sustainable development.
