Physical and Oxidative Stability of Low-Fat Fish Oil-in-Water Emulsions Stabilized with Black Soldier Fly (Hermetia illucens) Larvae Protein Concentrate

The physical and oxidative stability of fish oil-in-water (O/W) emulsions were investigated using black soldier fly larvae (BSFL) (Hermetia illucens) protein concentrate as an emulsifier. To improve the protein extraction and the techno-functionality, defatted BSFL powder was treated with ohmic heating (BSFL-OH) and a combination of ohmic heating and ultrasound (BSFL-UOH). Fourier transform infrared spectroscopy (FTIR) and differential scanning calorimetry (DSC) were performed in order to characterize the secondary structure and thermal stability of all protein concentrate samples. The interfacial properties were evaluated by the pendant drop technique. The lowest interfacial tension (12.95 mN/m) after 30 min was observed for BSFL-OH. Dynamic light scattering, ζ-potential and turbiscan stability index (TSI) were used to evaluate the physical stability of emulsions. BSFL-OH showed the smallest droplet size (0.68 μm) and the best emulsion stability (TSI = 8.89). The formation of primary and secondary volatile oxidation products and consumption of tocopherols were evaluated for all emulsions, revealing that OH and ultrasound treatment did not improve oxidative stability compared to the emulsion with untreated BSFL. The results revealed the promising application of BSFL proteins as emulsifiers and the ability of ohmic heating to improve the emulsifying properties of BSFL proteins.
Large-Scale Internet of Things Multi-Sensor Measurement Node for Smart Grid Enhancement

Electric power infrastructure has revolutionized our world and our way of living has completely changed. The necessary amount of energy is increasing faster than we realize. In these conditions, the grid is forced to run against its limitations, resulting in more frequent blackouts. Thus, urgent solutions need to be found to meet this greater and greater energy demand. By using the internet of things infrastructure, we can remotely manage distribution points, receiving data that can predict any future failure points on the grid. In this work, we present the design of a fully reconfigurable wireless sensor node that can sense the smart grid environment. The proposed prototype uses a modular developed hardware platform that can be easily integrated into the smart grid concept in a scalable manner and collects data using the LoRaWAN communication protocol. The designed architecture was tested for a period of 6 months, revealing the feasibility and scalability of the system, and opening new directions in the remote failure prediction of low voltage/medium voltage switchgears on the electric grid.

A Novel Active Fault-Tolerant Tracking Control for Robot Manipulators with Finite-Time Stability

Many terminal sliding mode controllers (TSMCs) have been suggested to obtain exact tracking control of robotic manipulators in finite time. The ordinary method is based on TSMCs that secure trajectory tracking under the assumptions such as the known robot dynamic model and the determined upper boundary of uncertain components. Despite tracking errors that tend to zero in finite time, the weakness of TSMCs is chattering, slow convergence speed, and the need for the exact robot dynamic model. Few studies are handling the weakness of TSMCs by using the combination between TSMCs and finite-time observers. In this paper, we present a novel finite-time fault tolerance control (FTC) method for robotic manipulators. A finite-time fault detection observer (FTFDO) is proposed to estimate all uncertainties, external disturbances, and faults accurately and on time. From the estimated information of FTFDO, a novel finite-time FTC method is developed based on a new finite-time terminal sliding surface and a new finite-time reaching control law. Thanks to this approach, the proposed FTC method provides a fast convergence speed for both observation error and control error in finite time. The operation of the robot system is guaranteed with expected performance even in case of faults, including high tracking accuracy, small chattering behavior in control input signals, and fast transient response with the variation of disturbances, uncertainties, or faults. The stability and finite-time convergence of the proposed control system are verified that they are strictly guaranteed by Lyapunov theory and finite-time control theory. The simulation performance for a FARA robotic manipulator proves the proposed control theory’s correctness and effectiveness.
What direct and indirect factors enable knowledge and skill sharing in community gardens

Concerns about the decline in knowledge concerning food growing stemming stem from the Green Revolution, as well as the rapid urbanization since the beginning of the 20th Century. There is a gap in the literature about community gardening in industrialized English-speaking countries, and since sharing of knowledge is a well-documented achievement of community gardens, the aim of this thesis is to find out what direct and indirect factors enable knowledge and skill sharing in community gardens. Using action research methodology, four gardens in Calgary, Canada were used as case studies, in which a total of eight participants were interviewed. This was complemented by a city-wide questionnaire for community gardeners. Encouraging personal satisfaction and using appropriate practical approaches were direct factors, and creating a positive atmosphere in an appropriate space, developing networks, and securing resources were indirect factors contributing to knowledge and skill sharing in gardens. Outcomes included how the roles gardeners take could increase social capital, why inter-garden networking is not thought of as a priority, and that Reflexive Learning is a useful way to approach the subjective aspects of gardening. Possibly the biggest contribution is that knowledge and skill sharing is merely the tip of the iceberg lettuce, and has unique synergies where it is dependent on and contributes to these direct and indirect factors. Finally, proposed action and further research are suggested.

Dietary Behaviour and Nutrition in Patients with COPD Treated with Long-Term Oxygen Therapy

Background: It is the first study in Poland and one of the first in the world to assess the nutrition of patients with chronic obstructive pulmonary disease (COPD) treated with long-term oxygen therapy (LTOT). Methods: The study group consisted of 110 COPD patients treated with LTOT. Anthropometric measurements and spirometry were performed. The diet of patients was assessed using a 3-day nutrition diary. Results: When assessing the degree of airflow obstruction (FEV1% N) depending on the BMI in patients treated with LTOT, a statistically significant correlation was demonstrated between the BMI and the value of the FEV% N parameter (p = 0.0093). Patients with COPD with a BMI >30 had statistically significantly higher values of FEV1% N than patients with a BMI in the range of 20–24.9 (p = 0.0278). Intake of calcium, vitamins A, C, D, E and folates was lower than the recommended daily intake in more than 95% of COPD patients. Conclusions: The diet of COPD patients treated with long-term oxygen therapy was improperly balanced, with deficiencies of important nutrients. Airflow obstruction in the respiratory tract was significantly smaller in obese patients, and greater in patients with diagnosed malnutrition.
The Role of TQM Practices in Technological Innovation: The Portuguese Footwear Industry Case

Abstract The relationship between TQM and innovation is complex. Literature suggests that the role of TQM varies according to the type of innovation we intend to introduce, essentially favouring incremental innovation while possibly being detrimental to radical innovation. The Portuguese footwear industry is dominated by small-to-medium units with a lack of resources to carry out radical innovations. Cases of success identified in the industry clearly show the importance of developing a close relationship with customers, suppliers, competitors and institutions, which allows the constant introduction of changes in processes and product designs. Based on the literature review and case studies research, we have developed a survey instrument that was administered to a set of small and medium size firms. Data thus collected is used in this paper to investigate the relationship between key TQM principles, especially those with regard to people management and work organisation issues, and firms' technological innovation.
Protocadherin-7 Regulates Osteoclast Differentiation through Intracellular SET-Binding Domain-Mediated RhoA and Rac1 Activation

Protocadherin-7 (Pcdh7) is a member of the non-clustered protocadherin δ1 subgroup of the cadherin superfamily. Although the cell-intrinsic role of Pcdh7 in osteoclast differentiation has been demonstrated, the molecular mechanisms of Pcdh7 regulating osteoclast differentiation remain to be determined. Here, we demonstrate that Pcdh7 contributes to osteoclast differentiation by regulating small GTPases, RhoA and Rac1, through its SET oncoprotein binding domain. Pcdh7 is associated with SET along with RhoA and Rac1 during osteoclast differentiation. Pcdh7-deficient (Pcdh7−/−) cells showed abolished RANKL-induced RhoA and Rac1 activation, and impaired osteoclast differentiation. Impaired osteoclast differentiation in Pcdh7−/− cells was restored by retroviral transduction of full-length Pcdh7 but not by a Pcdh7 mutant that lacks SET binding domain. The direct crosslink of the Pcdh7 intracellular region induced the activation of RhoA and Rac1, which was not observed when Pcdh7 lacks the SET binding domain. Additionally, retroviral transduction of the constitutively active form of RhoA and Rac1 completely restored the impaired osteoclast differentiation in Pcdh7−/− cells. Collectively, these results demonstrate that Pcdh7 controls osteoclast differentiation by regulating RhoA and Rac1 activation through the SET binding domain.
A DNA structure-based bionic wavelet transform and its application to DNA sequence analysis

DNA sequence analysis is of great significance for increasing our understanding of genomic functions. An important task facing us is the exploration of hidden structural information stored in the DNA sequence. This paper introduces a DNA structure-based adaptive wavelet transform WT --the bionic wavelet transform BWT --for DNA sequence analysis. The symbolic DNA sequence can be separated into four channels of indicator sequences. An adaptive symbol-to-number mapping, determined from the structural feature of the DNA sequence, was introduced into WT. It can adjust the weight value of each channel to maximise the useful energy distribution of the whole BWT output. The performance of the proposed BWT was examined by analysing synthetic and real DNA sequences. Results show that BWT performs better than traditional WT in presenting greater energy distribution. This new BWT method should be useful for the detection of the latent structural features in future DNA sequence analysis.
Applying Frameworks to Manage SoS Architecture

Abstract: As systems become more complex, managing the development of these systems becomes more challenging. Additionally the integration of multiple independent systems increases the management challenge. A System of Systems (SoS) has unique attributes which bring about unique management challenges. Architecture frameworks exist to organize and manage information about an architecture, and can be used to manage SoS architecture. One proposed approach was a framework that spans from component to enterprise, where enterprise is a SoS. A potential problem for this approach is that the lower half of the framework (from system down), is constructed using a reductionist approach while the upper part of the framework is constructed using a composition approach—that is, it is constructed by combining systems to make the broader enterprise system or SoS. So, does it stand to reason that the management approach for systems development should be the same as for SoS development? This article addresses some of the reasons why they should be managed differently, and offers a methodology for implementing the widely accepted Zachman Framework to facilitate the managing of SoS architectures.

Impacts of Entrepreneur Traits on Proactive Behaviors Strategy

Although scholars have been aware of the importance of proactive behaviors strategy in the entrepreneurial activity, however, which factors influence the proactive behaviors strategies have not been intensively studied. This thesis is based on the trait theory, analyzing the impacts of entrepreneur traits on proactive behaviors strategy deeply. Through the research and analysis of data on 152 start-up companies in Changchun, the results show that risk-taking propensity has no obvious effect on proactive behaviors strategy, but the need for achievement and the internal locus of control of entrepreneur traits have significant positive effect on proactive behaviors strategy. The conclusion of the study has important significance in enriching traits theory and the entrepreneurial orientation theory.
Combustion System Damping Augmentation With Helmholtz Resonators

This paper describes an analytical and experimental investigation to enhance combustion system operability using side branch resonators. First, a simplified model of the combustion system dynamics is developed in which the large amplitude pressure oscillations encountered at the operability limit are viewed as limit cycle oscillations of an initially linear instability. Under this assumption, increasing the damping of the small amplitude combustion system dynamics will increase combustor operability. The model is then modified to include side branch resonators. The parameters describing the side branch resonators and their coupling to the combustion system are identified, and their influence on system stability is examined. The parameters of the side branch resonator are optimized to maximize damping augmentation and frequency robustness. Secondly, the model parameters for the combustor and side branch resonator dynamics are identified from experimental data. The analytical model predicts the observed trends in combustor operability as a function of the resonator parameters and is shown to be a useful guide in developing resonators to improve the operability of combustion systems.

Novel design of stacked circularly polarized strip lines fed patch antenna has been proposed for global navigation satellite system in this article. The antenna has been designed to operate for the satellite navigation frequencies including GPS, global navigation satellite system, Galileo and Compass (1100—1600 MHz). Three normal Wilkinson power dividers are connected together acting as the feeding networks. As a result, the antenna has a 57.6% 10‐dB return loss bandwidth from 1.05 to 1.9 GHz and 42.9% 3‐dB axial ratio bandwidth from 1.1 to 1.7 GHz, respectively. Crossed slots are cut on the radiating patch to increase the antenna gain. The designed antenna in this article can acquire broad beam width and good axial ratio at low elevations. © 2013 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:2062–2066, 2013
Electrically small huygens source antenna for linear polarisation

We study the possibility of creating a Huygens source antenna for linear polarisation with good matching to a 50 Ω feeding cable. For this purpose, we design two identical radiating elements, both comprising one electric and one magnetic dipole. The dimensions of these radiating elements are optimised numerically to obtain equally strong radiation from the electric and magnetic dipoles. The optimised prototype is then manufactured and its radiation properties are measured.
Motor Skill, Motor Planning, and Motor Performance in Adults with Severe Mental Illnesses and Obesity

Abstract Motor functioning in persons with serious mental illness (SMI) is not well studied. We assessed motor functioning in people with SMI (n = 15) vs. adults with obesity (n = 15) and healthy controls (n = 15). Motor skills were assessed using balance and coordination tests. Motor planning and performance were assessed in Obstacle and Metronome Walking Tasks. The SMI group scored lower on balance and coordination tests (all ps < 0.001), and took longer steps when approaching obstacles (all ps < 0.001), but had unimpaired motor performance on the Metronome Walking Task. In obesity, excess body mass impairs motor skills, which adversely impacts motor performance. In persons with SMI, motor performance was unimpaired, with cognitive and neuroanatomical abnormalities likely underlying balance, coordination, and motor skill challenges.
Enhancement of power measurement using a modified method based on wavelet with preprocessing: electric arc furnace case study

In this paper, a new method is proposed for fundamental power calculation based on a wavelet transform with preprocessing by the Hilbert transform. The proposed method increases the frequencies of all harmonics by half of the main frequencies and locates both odd and even harmonics in the centres of the extracted frequency bands. Unlike the conventional method, there is no frequency interference and the fundamental power calculation is enhanced. In order to examine the proposed method, the steel electric arc furnace (EAF) of the Mobarakeh Steel Company, Esfahan, Iran is simulated in MATLAB software at the early stage of charging. Then the fundamental active, reactive and apparent power of the EAF are calculated using simulated and real data. Results confirm the effectiveness of the proposed method.

Impact of different pathogen reduction technologies on the biochemistry, function, and clinical effectiveness of platelet concentrates: An updated view during a pandemic

Standard platelet concentrates (PCs) stored at 22°C have a limited shelf life of 5 days. Because of the storage temperature, bacterial contamination of PCs can result in life‐threatening infections in transfused patients. The potential of blood components to cause infections through contaminating pathogens or transmitting blood‐borne diseases has always been a concern. The current safety practice to prevent pathogen transmission through blood transfusion starts with a stringent screening of donors and regulated testing of blood samples to ensure that known infections cannot reach transfusion products. Pathogen reduction technologies (PRTs), initially implemented to ensure the safety of plasma products, have been adapted to treat platelet products. In addition to reducing bacterial contamination, PRT applied to PCs can extend their shelf life up to 7 days, alleviating the impact of their shortage, while providing an additional safety layer against emerging blood‐borne infectious diseases. While a deleterious action of PRTs in quantitative and qualitative aspects of plasma is accepted, the impact of PRTs on the quality, function, and clinical efficacy of PCs has been under constant examination. The potential of PRTs to prevent the possibility of new emerging diseases to reach cellular blood components has been considered more hypothetical than real. In 2019, a coronavirus‐related disease (COVID‐19) became a pandemic. This episode should help when reconsidering the possibility of future blood transmissible threats. The following text intends to evaluate the impact of different PRTs on the quality, function, and clinical effectiveness of platelets within the perspective of a developing pandemic.
