Myrmecodia pendens Bulb Extract in the Lele Dumbo (Clarias gariepinus) Feed: Effects on the Growth Performance, Survival, and Blood Indices

This feeding experiment was performed to determine the effects of Myrmecodia pendens bulb extract (MBE) supplementation in fish feed on the growth, survival, and hemato-biochemical profile of Clarias gariepinus. A group of fish was fed with 0.25; 0.50; 1.0; 2.0% MBE and compared to control group (without MBE) for 75 days observation. At the end of feeding trial, growth parameters, hematological profile such as red blood cells (RBC), white blood cells (WBC), Hemoglobin (Hb), Hematocrit (Htc), differential leukocyte, blood plasma biochemistry (glucose, total albumin, cholesterol, and triglyceride), the hepatosomatic (HSI) and intestinal somatic index (ISI) were measured. Survival of all fish was also counted every two weeks. Supplementation MBE above 0.25% resulted significantly higher final biomass weight (FBW), body weight gain (BWG), daily weight gain (DWG), and average weekly gain (AWG). Meanwhile, fish group fed dietary MBE above 1.0% had significantly higher specific growth rate (SGR) (3.32±0.15) than other groups. Fish fed 1.0% of MBE also showed better value of feed conversion ratio (FCR) (1.13±0.03), Hb, and HSI compared to others group. Survival, neutrophil, monocyte, and ISI of all groups was not affected by any concentration of MBE supplementation. Dietary MBE above 0.5% enhanced RBC, WBC, Hematocrit, platelet (PLT), lymphocyte, blood plasma biochemistry such as glucose, total albumin, and triglyceride. Cholesterol of fish fed MBE in the diet showed incrementally enhanced. Present finding suggested that 1.0% MBE in the diet of Clarias gariepinus is recommended to enhance growth, survival, and blood profiles
Reviewing findings on the polypeptide sequence of the SARS-CoV-2 S-protein to discuss the origins of the virus

Several investigations suggested origins of SARS-CoV-2 from the recombination of coronaviruses of various animals, including the bat Rhinolophus affinis and the pangolin Manis javanica, despite the processes describing the adaptation from a reservoir of animals to human are still debated. In this perspective, I will remark two main inconsistencies on the origins of SARS-CoV-2: polypeptide sequence alignment of the S-proteins does not return the expected identity of the receptor-binding motif among most of pangolin-CoVs and SARS-CoV-2; accurate referencing for samplings and sequencing deposition of the ancestral bat coronavirus named RaTG13 was missing since the first reports on the SARS-CoV-2 coronavirus. This contribution aims to stimulate discussion about the origins of SARS-CoV-2 and considers other intermediate hosts as a reservoir for coronavirus.
Seismic calculations of directly buried gas-insulated transmission lines (GIL)

Gas Insulated transmission Line (GIL) is very well known for its high transmission rating of electrical power and its reliability. The high capacity of the transmission, the thermal, mechanical and the electrical behaviour of the new generation of the directly buried GIL were studied and tested by laying it in the ground in a long term test. To know the behaviour of the GIL in case of an earthquake, it is difficult to test a long length of the system by using a shaking table. So a seismic simulation with a help of finite element analysis with different accelerations has been done and confirmed that the line withstands the combination of the acceleration 0.5 g in both vertical and horizontal directions without any damage. The Von Mises stress is under the elastic limit by using an aluminium alloy for the conductor and for the enclosure.
Human Systematic Innovation Helix: Knowledge Management, Emotional Intelligence and Entrepreneurial Competency

This study analyzes the relationship between the innovation capacity of Spanish companies through the ability to obtain their information through the integration of these three variables: knowledge management, emotional intelligence, and entrepreneurial competency of Spanish executives. The questionnaires were distributed to executives of companies from different sectors of activity. The sample consists of 241 executives. The hypothesis was examined by structural equation modeling. Regarding the direct effects, the hypothesis testing result proves that the knowledge management of executives exerts a positive effect on Innovation, and, the entrepreneurial competency of executives exerts a positive effect on innovation. However, the influence of EI on innovation is not significant. The indirect effect shows that the integration of knowledge management, emotional intelligence and entrepreneurial competency of executives exert a positive statistical effect on Innovation at enterprises. This paper contributes with both, scientific and socio-economic impacts. Scientific impact, generating new knowledge that strengthens the value of executives as a catalyst for innovation; and, socio-economic impact, originating the human systematic innovation helix, a new socio-economic management tool to develop knowledge management capacity, socio-emotional abilities, and entrepreneurial competencies of executives, which acts as a lever to boost the results of innovation at companies.
Altered Spinal Homeostasis and Maladaptive Plasticity in GFAP Null Mice Following Peripheral Nerve Injury

The maladaptive response of the central nervous system (CNS) following nerve injury is primarily linked to the activation of glial cells (reactive gliosis) that produce an inflammatory reaction and a wide cellular morpho-structural and functional/metabolic remodeling. Glial acidic fibrillary protein (GFAP), a major protein constituent of astrocyte intermediate filaments (IFs), is the hallmark of the reactive astrocytes, has pleiotropic functions and is significantly upregulated in the spinal cord after nerve injury. Here, we investigated the specific role of GFAP in glial reaction and maladaptive spinal cord plasticity following sciatic nerve spared nerve injury (SNI) in GFAP KO and wild-type (WT) animals. We evaluated the neuropathic behavior (thermal hyperalgesia, allodynia) and the expression of glial (vimentin, Iba1) and glutamate/GABA system markers (GLAST, GLT1, EAAC1, vGLUT, vGAT, GAD) in lumbar spinal cord sections of KO/WT animals. SNI induced neuropathic behavior in both GFAP KO and WT mice, paralleled by intense microglial reaction (Iba1 expression more pronounced in KO mice), reactive astrocytosis (vimentin increase) and expression remodeling of glial/neuronal glutamate/GABA transporters. In conclusion, it is conceivable that the lack of GFAP could be detrimental to the CNS as it lacks a critical sensor for neuroinflammation and morpho-functional–metabolic rewiring after nerve injury. Understanding the maladaptive morpho-functional changes of glial cells could represent the first step for a new glial-based targeted approach for mechanisms of disease in the CNS.
A Variable Configuration Force Sensor With Adjustable Resolution for Robotic Applications

Multitask measurements with different measuring ranges and resolutions have put forward higher requirements for force sensors. This article presents a novel variable configuration approach to develop an adjustable-resolution force sensor with a compact force-sensitive structure. Unlike the traditional strain gauge-based force measurement, the external force is detected through measuring the displacement of the deformed structure with a precision optical linear encoder. This approach can enable variable measuring range and force resolution through the continuous adjustment of structural stiffness. Specifically, the stiffness adjustment is implemented by changing the second moment of area of the sensor structure through rotating its build-in flexure beam shafts. Analytical models are established to provide the theoretical basis for analysis and design of the sensor. Furthermore, the validity of the design is evaluated with finite element simulations. Finally, a sensor prototype is developed for performance evaluation, and applied for the wire bond pull tests to evaluate the bond strength on the printed circuit board assembly. Experimental results show that it is effective to change the measuring range and force resolution of the developed force sensor through the stiffness adjustment.
Multiple target tracking using retrodirective antenna arrays

In this paper the behavioural response of a frequency offset retrodirective antenna array [1 ] in the presence of multiple signals at different frequencies is investigated. It is shown that when separate frequency sources exist, the re-transmited beam of the retrodirective array will split into multiple beams, with each re-transmitted beam forming in the direction of the respective incoming source frequency. Measurements were performed on the retrodirective array in the presence of two closely spaced sources operating at frequencies within the bandwidth of the array and it is shown that the retrodirective array can simultaneously respond to each individual signal proving its usefulness in mobile wireless applications where multiple signal tracking is required.
Mucoadhesive Nanocarriers as a Promising Strategy to Enhance Intracellular Delivery against Oral Cavity Carcinoma

Oral cancer, particularly squamous cell carcinoma (SCC), has posed a grave challenge to global health due to its high incidence, metastasis, and mortality rates. Despite numerous studies and favorable improvements in the therapeutic strategies over the past few decades, the prognosis of this disease remains dismal. Moreover, several drawbacks are associated with the conventional treatment; including permanent disfigurement and physical impairment that are attributed to surgical intervention, and systemic toxicity that results from aggressive radio- or chemotherapies, which impacts patients’ prognosis and post-treatment quality of life. The highly vascularized, non-keratinized oral mucosa appears as a potential route for cytotoxic drug administration in treating oral cancer. It acts as a non-invasive portal for drug entry targeting the local oral lesions of the early stages of cancer and the systemic metastasis sites of advanced cancer. The absorption of the poorly aqueous-soluble anti-cancer drugs can be enhanced due to the increased permeability of the ulcerous mucosa lining in the disease state and by bypassing the hepatic first-pass metabolism. However, some challenges in oral transmucosal drug delivery include the drugs’ taste, the limited surface area of the membrane lining the oral cavity, and flushing and enzymatic degradation by saliva. Therefore, mucoadhesive nanocarriers have emerged as promising platforms for controlled, targeted drug delivery in the oral cavity. The surface functionalization of nanocarriers with various moieties allows for drug targeting, bioavailability enhancement, and biodistribution at the site of action, while the mucoadhesive feature prolongs the drug’s residence time for preferential accumulation to optimize the therapeutic effect and reduce systemic toxicity. This review has been focused to highlight the potential of various nanocarriers (e.g., nanoparticles, nanoemulsions, nanocapsules, and liposomes) in conferring targeting, solubility and bioavailability enhancement of actives and mucoadhesive properties as novel tumor-targeted drug delivery approaches in oral cancer treatment.
Mitigation of inter-area power oscillations by using UPFC control system with Fuzzy and Self-Tuning Controller

The purpose of the proposed Adaptive Self-Tuning (ST) Controller is to supplement its existing PI-UPFC control system for damping the inter-area low frequency oscillations in large-scale inter-connected power system is presented in this paper because PI controller parameters are fixed at certain operating point, unless retuned it suffers from insufficient dynamic performance for wide ranges of operating conditions. In order to overcome this problem, the author propose an adaptive supplementary controller with PI controller that tracks the system changes online through its Constrained Recursive Least Square (CRLS) identifier and also eliminates the effort of manual parameter re-tuning through its PS control algorithm. Further to improve the damping capability of the system, this paper propose a new method which uses an adaptive ST controller based UPFC using Fuzzy logic controller for damping inter-area oscillations. Simulation results shows that the UPFC based Fuzzy controller is superior to the
Developing a resilience index for safer and more resilient arctic shipping

ABSTRACT The growth of Arctic shipping requires effective tools to assess the appropriateness of existing practices on safety and resilience levels, especially in the enforcement of the Polar Code. Understanding such, in this study, we develop a resilience index using the Fuzzy Analytical Hierarchy Process (FAHP). Data collection for the index’s implementation started during a research voyage along the Northwest Passage in Canada. It resulted in 61 valid responses, upon which the relative importance and the level of satisfaction of resilience builders were investigated. The findings indicate that factors that rank high on importance are, in many cases, not that high on satisfaction. This presents dilemmas regarding the effectiveness of the current practices in promoting safe and resilient Arctic shipping management practices. This study fills an important gap in the monitoring of safety and resilience practices in Arctic shipping. In turn, this affects the future actions and research of researchers, stakeholders, and right-holders in the Arctic area.

Effects of parameter variation in DFIG-based grid connected system with a FACTS device for small-signal stability analysis

For the last few decades, there has been rising concern across the globe about depletion of conventional energy sources and the consequent energy crisis. Simultaneously, search for other energy sources, such as wind energy and solar energy, has been gaining momentum as well. Particularly, wind energy has become a viable alternative source of energy. As the wind power penetration continually increases, stability of the grid-connected doubly fed induction generator (DFIG)-based wind turbine system has become essential for wind power generation. This study presents the influence of a grid-side converter current dynamics on the small-signal stability by using the eigenvalue and participation factor technique which provides five distinct system modes, namely mechanical (M), stator electrical, converter electrical, electro-mechanical and non-oscillatory mode. In addition, flexible alternating current transmission system device has been incorporated to examine its effect on the system stability at different compensation levels. Furthermore, the sensitivity of a grid-connected DFIG system concerning system parameter variations and its impact on stability of the system modes has been investigated. Simulations have been carried out in the MATLAB/Simulink environment.
Netzwerkstrategien von „Housing Commons“ in der Gründungsphase – Das Beispiel der „habiTAT“-Hausprojekte „SchloR“ und „Bikes and Rails“ in Wien

housing projects have made explicit use of translocal networks in order to collectivise housing successfully. On this basis, the projects contribute – far beyond their own needs – to the establishment of a (trans-)local knowledge and expert network across commons, and the commoners provide thought-provoking impulses for the repoliticisation of non-profit social housing policy in Vienna and Austria.
A Fast Star Identification Algorithm of Star Sensors in the LIS Mode

In the South Atlantic Anomaly (SAA) area, due to the influence of transient noise caused by space radiation, a star sensor can easily stay in the lost-in-space (LIS) mode for a long time. To solve this problem, this paper proposes a fast star identification (FSI) algorithm. First, a noise suppression method based on scale assessment and neighborhood comparison is developed. Next, a fast and accurate search technique of multiple main stars based on the k-vector technique is used to realize star identification. The search technique builds a self-defined attribute database of stars, and a fast search method of a repeated star identity is proposed to realize the positioning of the main star. Lastly, the final main stars are obtained through the comparison of field of view and verification of angular distance. The experimental results showed that when the star sensor works at a speed of 0.1°/s and the level of transient noise signals is lower than 900, the successful identification rate is higher than 70%. In addition, compared with the triangle algorithm, match group algorithm, and multi-pole algorithm (MPA), the proposed FSI algorithm has the advantages of a higher successful identification rate and a faster execution speed.
Local Time Variations of the Equatorial Electrojet in Simultaneous Response to Subauroral Polarization Streams During Quiet Time

Based on 1‐year equatorial electrojet (EEJ) measurements from Swarm, and ion velocity from the Defense Meteorological Satellite Program, this study first examines the simultaneous effects of the subauroral polarization streams (SAPS) on EEJ during quiet time. The changes in EEJ (ΔEEJ) vary significantly with local time. ΔEEJ flows westward at dawn and is gradually enhanced to eastward at dusk. The eastward ΔEEJ at post‐noon might be driven indirectly by the upward electric field associated with SAPS electric field at SAPS channel, whereas ΔEEJ at pre‐noon might be directly attributed to the penetrating SAPS‐related polarization electric field. Under stronger geomagnetic forcing, a stronger intensity of westward ΔEEJ at dawn and noon is produced, whereas a stronger eastward ΔEEJ at dusk is generated because of a faster SAPS velocity.

Minimization of Circulating Currents in Parallel DC-DC Boost Converter Using Non-Linear Droop Control for Battery Energy Storage System

Battery is considered the most dominant energy storage device for renewableenergy-based DC microgrid systems (RE-DCMG) because of its ability tostore energy for a longer duration. Here the power electronic converter playsa vital role, which acts as a bridge between the energy storage system and DCmicrogrid. One of the main reasons for the failure of battery systems due tothe failure of the power electronic converters. To improve the redundancy andconverter failure issues of battery energy storage systems (BESS), paralleloperation of multiple converters are required. However, the parallel operationfaces an issue of voltage imbalance between the converters which gives rise toan input circulating current. To address these issues, in this paper, we proposea nonlinear droop control based parallel DC-DC boost converter for battery energy storage system. The nonlinear droop control strategy ensures theequal battery current sharing between the parallel converters and good outputvoltage regulation. Moreover, SOC based controller avoids over-charging andover-discharging of the battery and the parallel converters ensure the redun-dancy in operation. The proposed system is designed and implemented in theMATLAB/Simulink and compared with the existing linear droop control.
