Power Subsystem Design for Micro-Satellites Using Super- Capacitor Energy Storage

Super-capacitors have been used in terrestrial applications as an alternative electrical energy storage medium to that of conventional chemical battery. This is due to their long cycle life and ability to supply high power at low mass and volume. The aim of this paper is to present results of a feasibility study in enabling super-capacitor as a Secondary Power Source (SPS) on micro-satellite platforms. This super-capacitor-based power subsystem is best suited for missions where the payloads, or the other subsystems on board, require continuous high power (e.g. 1kW) for short operating times (i.e. several seconds to a few minutes per orbit). This enables the operation of a high power consumption mission (e.g. radar imaging) on micro-satellite platforms and this may lead to a breakthrough in terms of platform choice for payloads. In order to replace the current battery based SPS on the satellite, the proposed super-capacitor-based power subsystem must be compatible with existing micro-satellite platform in terms of bus voltage range, available energy capacity, mass, and volume. This paper discusses the major issues concerning the development of super-capacitor-based power subsystem and provides possible solutions. These include development of voltage regulation method, designing cell management system with functionality of recovering capacitor bank failure and power bus architectures.
Enhanced Bacteremia in Dextran Sulfate-Induced Colitis in Splenectomy Mice Correlates with Gut Dysbiosis and LPS Tolerance

Because both endotoxemia and gut dysbiosis post-splenectomy might be associated with systemic infection, the susceptibility against infection was tested by dextran sulfate solution (DSS)-induced colitis and lipopolysaccharide (LPS) injection models in splenectomy mice with macrophage experiments. Here, splenectomy induced a gut barrier defect (FITC-dextran assay, endotoxemia, bacteria in mesenteric lymph nodes, and the loss of enterocyte tight junction) and gut dysbiosis (increased Proteobacteria by fecal microbiome analysis) without systemic inflammation (serum IL-6). In parallel, DSS induced more severe mucositis in splenectomy mice than sham-DSS mice, as indicated by mortality, stool consistency, gut barrier defect, serum cytokines, and blood bacterial burdens. The presence of green fluorescent-producing (GFP) E. coli in the spleen of sham-DSS mice after an oral gavage supported a crucial role of the spleen in the control of bacteria from gut translocation. Additionally, LPS administration in splenectomy mice induced lower serum cytokines (TNF-α and IL-6) than LPS-administered sham mice, perhaps due to LPS tolerance from pre-existing post-splenectomy endotoxemia. In macrophages, LPS tolerance (sequential LPS stimulation) demonstrated lower cell activities than the single LPS stimulation, as indicated by the reduction in supernatant cytokines, pro-inflammatory genes (iNOS and IL-1β), cell energy status (extracellular flux analysis), and enzymes of the glycolysis pathway (proteomic analysis). In conclusion, a gut barrier defect after splenectomy was vulnerable to enterocyte injury (such as DSS), which caused severe bacteremia due to defects in microbial control (asplenia) and endotoxemia-induced LPS tolerance. Hence, gut dysbiosis and gut bacterial translocation in patients with a splenectomy might be associated with systemic infection, and gut-barrier monitoring or intestinal tight-junction strengthening may be useful.
ASSEMBLY OF FULLERENE FINE CRYSTALS: FABRICATION OF 1D, 2D AND 3D STRUCTURES FROM 0D FULLERENE

Fullerene molecules with closed cage structures, extended π systems, excellent mechanical and photochemical stability and unique semiconducting properties are ideal blocks to construct various supramolecular assemblies and functional materials. Furthermore, zerodimensional fullerene molecules with only a single elemental component, carbon, without any charged or interactive functional groups are excellent units for self assembly. Researches on fullerene micro and nanostructures, especially crystallization of fullerene molecules into ordered molecular assemblies have grown rapidly during recent years. In this short review, we introduce various examples of self assembled fullerenes and their derivatives. An outline and background of fullerene properties are first described (introduced), followed by several examples of fullerene assemblies, such as wiskers, tubes, sheets, cubes, hole in cubes and hopper shaped fullerenes. Also a demonstration of factors influencing morphologies of fullerene assemblies and future applications of obtained crystals is done.
Ultrastructural analysis of homozygous mutant loco embryos reveals a severe glial cell differentiation defect. Mutant

Within the Drosophila nervous system, glial cells perform a variety of important functions. They are capable of controlling proliferation rates of neighboring neuroblasts (Ebens et al., 1993), they ensheath and electrically insulate axon bundles (Auld et al., 1995) and they are likely to secrete neurotrophic factors (Xiong and Montell, 1995). Furthermore, during embryonic development, neuron-glia interactions are required for the correct establishment of the axonal scaffold (Jacobs and Goodman, 1989; Klämbt and Goodman, 1991; Goodman and Doe, 1993; Hidalgo et al., 1995; Hosoya et al., 1995; Jones et al., 1995; Klämbt et al., 1996). Based on position and gene expression, embryonic CNS glial cells can be divided into two major classes, the midline glia and the lateral glia (Klämbt et al., 1996). The lateral glial cells are a heterogeneous group of cells, characterised by the expression of a number of genes encoding transcription factors. The lineage relationships of these cells have been described (Jacobs et al., 1989; Bossing et al., 1996; Schmidt et al., 1997). Lateral glia development is initiated by the activity of the gene glial cells missing(gcm), which acts as a master regulatory gene of glial cell development (Hosoya et al., 1995; Jones et al., 1995; Vincent et al., 1996). gcm encodes a novel transcription factor with an 8-nucleotide DNA-binding site (Akiyama et al., 1996; Schreiber et al., 1997). In its absence, glial-specific gene expression is abolished and glial cells are transformed into neuronal cell types (Hosoya et al., 1995; Jones et al., 1995; Bernardoni et al., 1997). gcm governs glial development by activating transcription factors such as TRAMTRACK, POINTED and REPO, which in turn control glial differentiation by two different mechanisms (Hosoya et al., 1995; Jones et al., 1995; Giesen al., 1997). On the one hand, inappropriate, neuronal differentiation appears to be suppressed in developing glial cells by the BTB-Zn-finger domain protein TRAMTRACKP69 (Giesen et al., 1997). On the other hand, glial differentiation needs to be activated by transcription factors such as the POINTED ETS domain proteins or the REPO homeodomain protein (Campbell et al., 1994; Klaes et al., 1994; Xiong et al., 1994; Halter et al., 1995). pointedencodes two proteins, PNTP1 and PNTP2, which share a common ETS DNA-binding domain. Within the embryonic CNS, both POINTED proteins are specifically expressed in non1781 Development 126, 1781-1791 (1999) Printed in Great Britain © The Company of Biologists Limited 1999 DEV7707
FrictShoes: Providing Multilevel Nonuniform Friction Feedback on Shoes in VR

Many haptic feedback methods have been proposed to enhance realism in virtual reality (VR). However, friction on the feet in VR, which renders feedback as if walking on different terrains or ground textures or stepping on objects is still less explored. Herein, we propose a wearable device, FrictShoes a pair of foot accessories, to provide multilevel nonuniform friction feedback to feet. This is achieved by the independent functioning of six brakes on six wheels underneath each FrictShoe, which allows the friction levels of the wheels from each to be either matched or to vary. We conducted a magnitude estimation study to understand users' distinguishability of friction force magnitudes (or levels). Based on the results, we performed an exploratory study to realize how users adjust and map the multilevel nonuniform friction patterns to common VR terrains or ground textures. Finally, a VR experience study was conducted to evaluate the performance of the proposed multilevel nonuniform friction feedback to the feet in VR experiences.

Purpose – Although both institutional export assistance and entrepreneurial orientation (EO) contribute separately and positively to export performance, the interplay between them has received little attention. This study examines the role of international EO in deriving performance benefits from governmental and nongovernmental export assistance. Design/methodology/approach – In this longitudinal study, two surveys were administered at two different times: In 2011, 705 Bangladeshi apparel exporters were surveyed, and in 2019, a subsequent survey of 198 firms inmultiple industries was conducted. The aim of the surveyswas to assess the relationships between governmental and nongovernmental assistance, EO and export performance. Findings – The results of the first survey show that, while nongovernmental assistance influences performance directly and via EO, governmental assistance has only direct effects. Furthermore, the negative influence of government assistance on EO reduces the total effects and renders them nonsignificant. The results of the second survey demonstrate that government EPPs have both direct and indirect positive and significant effects on market performance, indicating a partial mediation, whereas quasi-governmental assistance has positive and significant direct effects as well as negative but nonsignificant indirect effects. Nongovernmental EPPs have both direct and indirect significant effects on international performance, indicating a partial mediation. Research limitations/implications – The study has important implications for researchers studying export assistance and its impact on firm performance. Instead of adopting a parochial view of government assistance, this study categorizes such assistance into three types – government, quasi-government and IMR 38,6
SoK: Social Cybersecurity

We analyze prior work in social cybersecurity and present a structuring of this literature based on its pertinence to four S&P-relevant social behaviors: (1) negotiating access to shared resources, (2) shared and social authentication, (3) managing self-presentation, and (4) influencing others’ S&P behaviors. We further break down these domains into four scales of social distance—intimate, personal, social, and public— showing that desired access control policies, authentication methods, and privacy and sharing preferences vary across these social scales. We evaluate the current landscape of work through the lens of Ackerman’s social-technical gap in social computing systems, finding that while social behaviors clearly impact S&P preferences and needs, existing S&P systems are designed with little understanding of these behaviors. This mismatch forces users to choose between implementing their ideal S&P policies or reducing social friction. To address this mismatch, we outline a research agenda for social cybersecurity work that better aligns S&P goals with social needs, preferences and behaviors.
Recovery Time and Its Predictors among Women Admitted with Obstetric Fistula in Jimma University Medical Center Southwest, Ethiopia: A Retrospective Cohort Study

Background: Obstetric fistula is one of the most shocking medical disabilities that women face as a result of problems caused by a lack of surgical intervention. Methods: From January 2011 to February 2017, a retrospective analysis was undertaken on obstetric fistula participants who received undergone surgical repair at the Jimma University Medical Center. Results: 81.4% of fistula patients were reported to have recovered. The results of lognormal inverse-Gaussian frailty model revealed that weight [≥]50kg ([FE]= 0.86, 95% CI: 0.747, 0.99), divorced ([FE]=1.2, 95% CI: 1.028, 1.413), urban residence ([FE]= 1.56, 95% CI: 01.046, 2.317), urine incontinence >3 months ([FE]=1.2, 95% CI: 1.056, 1.371), no antenatal care ([FE]=1.189, 95% CI: 1.023, 1.382), duration of labor <2days ([FE]= 0.86, 95% CI: 0.758, 0.986), health center delivery ([FE]= 0.76, 95% CI: 0.576, 0.989), vaginal delivery ([FE]= 1.5, 95% CI: 1.125, 1.996), and partially damaged urethra ([FE]=1.59, 95% CI: 1.168, 2.166) and recto-vaginal fistula([FE]= 0.735, 95%CI: 0.6045, 0.894) were associated with the recovery time. Conclusion: Patients with a weight < 50 kg, delivery at a health center, labor lasting <2 days, urinary incontinence lasting <3 months, antenatal care follow-up, cesarean section delivery, urethra status not damaged, and recto-vaginal fistula had a faster recovery period.
Early Tide Mills: Some Problems

The recent concern with energy problems has led to a reconsideration of the ways in which our forebears met their energy needs. Among the less important means available, which nonetheless was widely adopted along the western seaboard of Europe and the eastern seaboard of the Americas, was the tide mill. Despite the fact that stormy seas and seasonal variations in the tides lessened efficiency and sometimes made operation precarious, while the daily time lag of the tide demanded a constantly altering work regime, about 750 tide mills are known to have been in operation at one time or another along the shores of the Atlantic. ' In its normal form, the tide mill was a water mill with an undershot waterwheel which was driven by tidal water ebbing from a pool in which it had been impounded as the tide flowed. But when, where, and for what purposes tide mills were first employed has as yet not been firmly established, and the current state of knowledge is confusing. In this note, therefore, I propose to set out some of the issues and to assess the evidence available. Where, then, were tide mills established in the Middle Ages? The various sites will be discussed in the following order: Basra, the Adriatic, Dover, France, England, the Low Countries, Portugal, Spain, and Italy.2 A. Basra. -Without giving his reference, the late R. J. Forbes wrote that "the coastal town of Basra on the Persian Gulf even had tide mills, mostly for grinding corn. "3 The source of his information could well have been an edition of the work of the great Muslim geographer, al-Maqdisi, Shams al-Din, who wrote: "The tide is a marvel and a
Numerical investigation on the effect of homogenous roughness due to biofouling on ship friction resistance

Ships are subject to increased surface roughness due to the attachment of biofoulings on their hull. When the surface of a ship’s hull is rough, increased frictional resistance can be expected. A ship’s frictional resistance make up almost 80 – 85% of its total resistance. Therefore, it is crucial to maintain the ship’s frictional resistance value to a minimum. In this study, the effects of roughness length scale due to biofouling on friction resistance are investigated. To achieve reliable results, this study used the 3D DTMB 5415 model that was established as a benchmark study by ITTC. Roughness length scales representing biofoulings are applied to the model and analyzed by using the CFD software at a service speed, reaching a Froude Number of 0.28. Results of the simulation are compared and analysed to gain an understanding of the increased friction resistance value due to biofouling. For the smooth case, the results are in agreement with the towing test conducted by ITTC. In addition, friction resistance is found to be increasing along with the rise of the roughness length scale.
Response strategies used to mitigate the effect of extreme weather on rural and remote housing in Australia

In the extreme climates of Australia, rural and remote locations have special site and dwelling requirements and therefore special design solutions. This can include construction constraints, bushfire risk, resource efficiency, comfort and respect for the surrounding environment and heritage. Existing regulations targeted at extreme weather impacts such as bushfire, flood, cyclones, and heatwaves often impact the design and material choices for rural and remote housing due to their exposed locations, including housing proposed for rebuild following damage resulting from an extreme weather event. These regulations also lead to increased costs and uncertainty about the suitability of rural land for construction, making it challenging for rebuilding communities in affected areas. Such well-intentioned regulations also create limitations on innovation through experimental / bespoke building design, such as; 1) novel solutions to extreme weather mitigation and resistance 2) material choices for construction; and 3) achievement of operational and embodied energy reductions. Experimental buildings provide significant innovation benefits to industry as is often seen in the development of sustainable and high-performance buildings. This research examines the academic and industry knowledge of current design regulations for extreme weather events and implications for experimental and innovative design, highlighting the challenges for buildings to achieve increasing standards of environmental performance whilst ensuring resilience in the face of increasing extreme weather events, with a specific focus on rural communities. Case study analysis is used to provide an understanding of the focus and strategies used by different groups in different locations to address the impacts of extreme weather.
Development of Lab-on-a-Disc Integrated with Resazurin-based Assay for Total Bacterial Counting in Raw Milk

The quality of milk and dairy products depends largely on micro-organisms contamination which can pose serious health risks. Therefore, the total viable count (TVC) in raw milk needs to be daily checked to guarantee high quality. A resazurin is used as a dye indicator for the TVC quality in raw milk. However, this method is relatively complicated and inconvenient for on-site measurement. During the wait time, changes in physical and chemical properties of the raw milk were observed and they might affect the accuracy of the test results. Therefore, lab-on-a-disc (LOAD), a low-cost, user-friendly, and fast detection centrifugal microfluidic platform for the TVC test, was proposed in this study. The LOAD device (ϕ: 9.0 cm) was fabricated by laser machining of polymethyl methacrylate (PMMA, acrylic) and assembled with pressure sensitive adhesive (PSA) films. The 10 %(v/v) of resazurin-based assay that incubated at 25 °C was used to detect three different bacterial concentration levels of 4.0 log CFU/mL (low), 6.0 log CFU/mL (medium) and 8.0 log CFU/mL (high) in raw milk. The reduction process changed the color from purple (resazurin) to pink (resorufin) and to white (dihydroresorufin) subsequently. The resazurin and resorufin showed the maximum absorbance at the wavelength of 600 and 570 nm, respectively. After the LOAD was rotated at 5000 rpm for 5 minutes at 25 °C, the color of resazurin in the raw milk with medium and high levels of bacterial concentration started to change from purple to pink at 60 and 15 min, respectively. However, the color of resazurin in raw milk with low level of bacterial concentration remained dark mauve after 120 min. Overall, the LOAD integrated with resazurin-based assay is an alternative method to determine TVC in raw milk and various food stuffs.

Application of stator shifting to five-phase fractional-slot concentrated winding interior permanent magnet synchronous machine

In many applications, interior permanent magnet synchronous machines (IPMSMs) with fractional slot concentrated windings (FSCWs) are considered promising candidates in terms of higher power density and efficiency. In addition, employing a multiphase stator winding improves the drive train availability and increases reliability. This study investigates the effect of applying stator shifting to five-phase FSCW winding IPMSMs to suppress the effect of the slot harmonics by doubling the number of slots. In this case, the winding coil pitch will be two, which stands as a compromise between single-tooth and distributed winding topologies. This highly improves the air gap flux distribution, significantly reduces both rotor core and magnet eddy current losses, and increases saliency ratio and reluctance torque component. Moreover, an improved performance under fault conditions, in terms of lower torque ripple, and core and magnet losses, adds to the main advantages of this technique. Various slot/pole combinations suitable for five-phase machines are investigated. A full simulation case study based on two-dimensional finite element analysis is applied to the 20-slot/18-pole stator with single-tooth winding under both healthy and open-circuit phase fault cases.
Will daytime community calcification reflect reef accretion on future, degraded coral reefs?

Abstract. Coral bleaching events continue to drive the degradation of coral reefs worldwide, causing a shift in the benthic community from coral- to algae-dominated ecosystems. Critically, this shift may decrease the capacity of degraded coral reef communities to maintain net positive accretion during warming-driven stress events (e.g., reef-wide coral bleaching). Here we measured rates of net ecosystem calcification (NEC) and net ecosystem production (NEP) on a degraded coral reef lagoon community (coral cover < 10 % and algae cover > 20 %) during a reef-wide bleaching event in February 2020 at Heron Island on the Great Barrier Reef. We found that during this bleaching event, rates of NEP and NEC across replicate transects remained positive and did not change in response to bleaching. Repeated benthic surveys over a period of 20 d indicated an increase in the percent area of bleached coral tissue, corroborated by relatively low Symbiodiniaceae densities (∼ 0.6 × 106 cm−2) and dark-adapted photosynthetic yields in photosystem II of corals (∼ 0.5) sampled along each transect over this period. Given that a clear decline in coral health was not reflected in the overall NEC estimates, it is possible that elevated temperatures in the water column that compromise coral health enhanced the thermodynamic favorability for calcification in other ahermatypic benthic calcifiers. These data suggest that positive NEC on degraded reefs may not equate to the net positive accretion of a complex, three-dimensional reef structure in a future, warmer ocean. Critically, our study highlights that if coral cover continues to decline as predicted, NEC may no longer be an appropriate proxy for reef growth as the proportion of the NEC signal owed to ahermatypic calcification increases and coral dominance on the reef decreases.
