Performance Analysis of a Low Head Water Vortex Turbine

Received: 04th May 2021 Revised: 18th November 2021 Accepted: 20th November 2021 Published: 23rd December 2021 A small hydropower plant is an environment-friendly renewable energy technology. The run-of-river type gravitational water vortex turbine can be designed to produce electricity at sites with low water heads. In this study, an experimental investigation was undertaken on this type of turbine with a water tank and a runner which is connected to a shaft. At the end of the shaft, a rope brake was attached to measure the output power, torque and overall efficiency of the vortex turbine by varying flow rates. The designed vortex turbine can achieve an overall efficiency of 52.67%. The experimental results were validated with available data in the literature and theories associated with the turbine. The results also showed that the flow rate plays a vital role in generating power, torque as well as overall efficiency. The project was completed using local resources and technologies. Moreover, as water is used as the input power, this project is eco-friendly which has no adverse effect on the environment.

Misogynoir: public online response towards self-reported misogynoir

"Misogynoir" refers to the specific forms of misogyny that Black women experience, which couple racism and sexism together. To better understand the online manifestations of this type of hate, and to propose methods that can automatically identify it, in this paper, we conduct a study on 4 cases of Black women in Tech reporting experiences of misogynoir on the Twitter platform. We follow the reactions to these cases (both supportive and non-supportive responses), and categorise them within a model of misogynoir that highlights experiences of Tone Policing, White Centring, Racial Gaslighting and Defensiveness. As an intersectional form of abusive or hateful speech, we investigate the possibilities and challenges to detect online instances of misogynoir in an automated way. We then conduct a closer qualitative analysis on messages of support and non-support to look at some of these categories in more detail. The purpose of this investigation is to understand responses to misogynoir online, including doubling down on misogynoir, engaging in performative allyship, and showing solidarity with Black women in tech.
Inveterate adult congenital clubfoot in a patient with myelomeningocele and the Ponseti method as a choice: case report

The Ponseti method is currently considered the gold standard for treating congenital clubfoot, including in syndromic cases such as myelomeningocele. Its indication in neglected cases is well established in children and adolescents but remains uncertain in adult patients. We present a clinical case of a 27-year-old female patient with myelomeningocele and neglected clubfoot who was treated for the first time at this age with the Ponseti method, with good results. In developing countries, we often encounter adult patients with congenital club feet who have not had access to health care. Although the age limit to institute the Ponseti method as a therapeutic option is still unclear, it is an inexpensive, safe, accessible, and plausible option with satisfactory results even in adult, neglected, and syndromic cases.

Meanwhile satisfaction is affected by trade off price and value, perceived augmentation, perceived usefulness, perceived enjoyment and system quality.
The Determinants of Entrepreneurial Intention among Generation Z during Covid-19 Pandemic: Evidence from Indonesia

Generation Z, known as people who grow with technology, have a preference for starting their own business which is estimated to be different than other generations during the covid-19 pandemic. Understanding their behavior becomes very important because they will become the next generation that drives the economic sector. This study aimed to investigate the key determinants of entrepreneurial intention among generation Z during the Covid-19 pandemic. 225 data were collected through online tools and analyzed using partial least square – structural equation modeling. The finding indicates that entrepreneurial intention among generation Z is positively correlated and influenced by family’s entrepreneurial tradition, profit orientation, and personality traits. This study used the family's entrepreneurial tradition and profit orientation as new variables which have received little attention to determine the entrepreneurial intention. The phenomenon of covid-19aa will bring new contributions to the field of management and entrepreneurship.
Ankle arthrodesis through Meary’s anterolateral access

Objective: This study aimed to assess indications for surgical treatment, position of the ankle, time and rate of fusion after arthrodesis; to ascertain whether the technique provides fusion rates similar to those described in the published literature; and to quantify patients’ improvement according to the AOFA and VAS scores, and patients’ satisfaction using a Likert scale. Methods: This is a clinical study with a cohort of 18 patients (9 women and 9 men) with a mean age of 49.10 years, conducted from 2006 and 2016. Results: Post-traumatic arthrosis (88.88%), rheumatoid arthritis (5.56%), and Charcot-Marie-Tooth disease (5.56%) motivated the surgeries. Six ankles fused in an equinus position, and 12 of them in a neutral position. Five ankles fused in valgus angulation, and 13 in a neutral position. Five ankles fused in external rotation, 2 in internal rotation and 11 in a neutral position. In the postoperative period, American Orthopaedic Foot and Ankle Society (AOFAS) and visual analogue scale (VAS) scores showed an improvement of 31.6 points and 5.1 points, respectively. Regarding the Likert scale, 2 patients reported being very satisfied, 14 satisfied, and 2 partially satisfied. Conclusion: Fusion in a 100% of cases and patients’ overall satisfaction have led to the conclusion that this treatment method is appropriate to attain ankle fusion, with results similar to those found in the medical literature.

Is It Stevens–Johnson Syndrome or MIS-C with Mucocutaneous Involvement?

Background Severe acute respiratory syndrome coronavirus-2 (SARS-COV-2) can be present in the form of multisystem inflammatory disease in children. Case Presentation. A 25-month-old boy presented with fever, malaise, diffuse maculopapular rashes, and mucosal involvement during the COVID-19 pandemic. He was first diagnosed with Stevens–Johnson syndrome (SJS). Further evaluation revealed lymphopenia, thrombocytopenia, and elevated levels of C-reactive protein (CRP), ferritin, and fibrinogen. This was followed by a positive polymerase chain reaction (PCR) test for COVID-19. In addition to receiving initial care for SJS, he was treated for MIS-C, which led to his recovery after four days. Conclusion COVID-19 infection should be considered in children with fever and dermatological features during the pandemic because it may cause different features of the multisystem inflammatory syndrome in children (MIS-C), suggestive of delayed hyperimmune response.
Forming relationships with stakeholders in engineering projects

For a project manager, it is vital to build good relations with the stakeholders who are identified as being most crucial in the project process and in using the final results of the project. The purpose of this paper is to study relationships in an engineering project setting; more specifically, the focus is on identifying the determining factors that form the relationship between the project and its stakeholders. This paper presents an empirical study based on in-depth interviews following a semistructured approach. Three engineering projects were studied in detail. Results from the current study identified five different types of relationships: classical market; through a third party; open and direct; integrated team; and partnering. Another finding indicates that five different factors have an impact on the formation of the project-stakeholder relationship: trust; uncertainty and control; culture and language; resources and knowledge; and goal congruence.

Objective Sleep Profile in LGI1/CASPR2 Autoimmunity.

STUDY OBJECTIVES Rapid eye movement (REM) sleep behavior disorder (RBD) and other sleep disturbances are frequent in leucine-rich, glioma inactivated protein 1-IgG (LGI1) and contactin-associated protein 2-IgG (CASPR2) autoimmunity, yet polysomnographic analyses of these disorders remain limited. We aimed to characterize clinical presentations and analyze polysomnographic manifestations, especially quantitative REM sleep without atonia (RSWA) in LGI1/CASPR2-IgG seropositive (LGI/CASPR2+) patients. METHODS We retrospectively analyzed clinical and polysomnographic features and quantitative RSWA between LGI1+/CASPR2+ patients and age-sex matched controls. Groups were compared with Wilcoxon rank-sum and chi-square tests. Combined submentalis and anterior tibialis (SM+AT) RSWA was the primary outcome. RESULTS Among 11 (LGI1+, n=9; CASPR2+, n=2) patients, Morvan syndrome sleep features were present in 7 (63.6%) LGI1+/CASPR2+ patients, with simultaneous insomnia and DEB in 3 (27.3%), and the most common presenting sleep disturbances were dream enactment behavior (DEB, n=5), insomnia (n=5), and sleep apnea (n=8; median apnea hypopnea index=15/hour). Median Epworth Sleepiness Scale (ESS) was 9 (range 3-24; n=10), with hypersomnia in 4 (36.4%). LGI1+/CASPR2+ patients had increased N1 sleep (p=0.02), decreased REM sleep (p=0.001), and higher levels of SM+AT any RSWA (p < 0.001). Eight of 9 (89%) LGI1+ exceeded RBD RSWA thresholds (DEB, n=5; isolated RSWA, n=3). RSWA was greater in anterior tibialis than submentalis. All 10 LGI1+/CASPR2+ patients treated with immunotherapy benefitted, and 5/10 had improved sleep disturbances. CONCLUSION LGI1/CASPR2-IgG autoimmunity is associated with prominent dream enactment, insomnia, RSWA, sleep apnea, and shallower sleep. Polysomnography provides objective disease markers in LGI1+/CASPR2+ autoimmunity and immunotherapy may benefit associated sleep disturbances.
Experimental investigation of the collapse modes and the main crushing characteristics of composite sandwich panels subjected to flexural loading

The flexural properties, collapse modes and crushing characteristics of various types of composite sandwich panels – that were candidate materials for the manufacture of the front-end bumper of transportation vehicles – were investigated in a series of three-point bending tests that were performed in accordance with the American Society for Testing and Materials International Standard D790. The tested hybrid composites were constructed trying four types of polymer foam core (more specifically polymethacrylimide foam, cross-linked and linear polyvinyl chloride foam and polyurethane foam) and two types of fibreglass reinforced polyester faceplate laminates made of glass fibre reinforcements impregnated in modified acrylic resin, in eight different material combinations. Two modes of collapse were recorded in the series of flexural tests: the first was foam core shear failure and the second was local indentation collapse mode. The influence of the most important material properties of the faceplate laminates and foam core and the sandwich construction geometry on the flexural response and the crushing characteristics of the tested sandwich panels such as the peak load, crash energy absorption and collapse modes is extensively analysed. Particular attention is paid to the analysis of the mechanics of progressive deformation and crumpling of the sandwich panels in each of the collapse modes emphasising the mechanisms related to the crash energy absorption during the bending of the sandwich panels.
Flowers prepare thyselves: leaf and root herbivores induce specific changes in floral phytochemistry with consequences for plant interactions with florivores

Summary The phenotypic plasticity of flowering plants in response to herbivore damage to vegetative tissues can affect plant interactions with flower‐feeding organisms. Such induced systemic responses are probably regulated by defence‐related phytohormones that signal flowers to alter secondary chemistry that affects resistance to florivores. Current knowledge on the effects of damage to vegetative tissues on plant interactions with florivores and the underlying mechanisms is limited. We compared the preference and performance of two florivores on flowering Brassica nigra plants damaged by one of three herbivores feeding from roots or leaves. To investigate the underlying mechanisms, we quantified expression patterns of marker genes for defence‐related phytohormonal pathways, and concentrations of phytohormones and glucosinolates in buds and flowers. Florivores displayed contrasting preferences for plants damaged by herbivores feeding on roots and leaves. Chewing florivores performed better on plants damaged by folivores, but worse on plants damaged by the root herbivore. Chewing root and foliar herbivory led to specific induced changes in the phytohormone profile of buds and flowers. This resulted in increased glucosinolate concentrations for leaf‐damaged plants, and decreased glucosinolate concentrations for root‐damaged plants. The outcome of herbivore–herbivore interactions spanning from vegetative tissues to floral tissues is unique for the inducing root/leaf herbivore and receiving florivore combination.
Evolution of behavioural control from chordates to primates

This article outlines a hypothetical sequence of evolutionary innovations, along the lineage that produced humans, which extended behavioural control from simple feedback loops to sophisticated control of diverse species-typical actions. I begin with basic feedback mechanisms of ancient mobile animals and follow the major niche transitions from aquatic to terrestrial life, the retreat into nocturnality in early mammals, the transition to arboreal life and the return to diurnality. Along the way, I propose a sequence of elaboration and diversification of the behavioural repertoire and associated neuroanatomical substrates. This includes midbrain control of approach versus escape actions, telencephalic control of local versus long-range foraging, detection of affordances by the dorsal pallium, diversified control of nocturnal foraging in the mammalian neocortex and expansion of primate frontal, temporal and parietal cortex to support a wide variety of primate-specific behavioural strategies. The result is a proposed functional architecture consisting of parallel control systems, each dedicated to specifying the affordances for guiding particular species-typical actions, which compete against each other through a hierarchy of selection mechanisms.

The evolution of quantitative sensitivity

The ability to represent approximate quantities appears to be phylogenetically widespread, but the selective pressures and proximate mechanisms favouring this ability remain unknown. We analysed quantity discrimination data from 672 subjects across 33 bird and mammal species, using a novel Bayesian model that combined phylogenetic regression with a model of number psychophysics and random effect components. This allowed us to combine data from 49 studies and calculate the Weber fraction (a measure of quantity representation precision) for each species. We then examined which cognitive, socioecological and biological factors were related to variance in Weber fraction. We found contributions of phylogeny to quantity discrimination performance across taxa. Of the neural, socioecological and general cognitive factors we tested, cortical neuron density and domain-general cognition were the strongest predictors of Weber fraction, controlling for phylogeny. Our study is a new demonstration of evolutionary constraints on cognition, as well as of a relation between species-specific neuron density and a particular cognitive ability.

Scaffolding layered control architectures through constraint closure: insights into brain evolution and development

The functional organization of the mammalian brain can be considered to form a layered control architecture, but how this complex system has emerged through evolution and is constructed during development remains a puzzle. Here we consider brain organization through the framework of constraint closure, viewed as a general characteristic of living systems, that they are composed of multiple sub-systems that constrain each other at different timescales. We do so by developing a new formalism for constraint closure, inspired by a previous model showing how within-lifetime dynamics can constrain between-lifetime dynamics, and we demonstrate how this interaction can be generalized to multi-layered systems. Through this model, we consider brain organization in the context of two major examples of constraint closure—physiological regulation and visual orienting. Our analysis draws attention to the capacity of layered brain architectures to scaffold themselves across multiple timescales, including the ability of cortical processes to constrain the evolution of sub-cortical processes, and of the latter to constrain the space in which cortical systems self-organize and refine themselves.

Glucose but Not Fructose Alters the Intestinal Paracellular Permeability in Association With Gut Inflammation and Dysbiosis in Mice

A causal correlation between the metabolic disorders associated with sugar intake and disruption of the gastrointestinal (GI) homeostasis has been suggested, but the underlying mechanisms remain unclear. To unravel these mechanisms, we investigated the effect of physiological amounts of fructose and glucose on barrier functions and inflammatory status in various regions of the GI tract and on the cecal microbiota composition. C57BL/6 mice were fed chow diet and given 15% glucose or 15% fructose in drinking water for 9 weeks. We monitored caloric intake, body weight, glucose intolerance, and adiposity. The intestinal paracellular permeability, cytokine, and tight junction protein expression were assessed in the jejunum, cecum, and colon. In the cecum, the microbiota composition was determined. Glucose-fed mice developed a marked increase in total adiposity, glucose intolerance, and paracellular permeability in the jejunum and cecum while fructose absorption did not affect any of these parameters. Fructose-fed mice displayed increased circulation levels of IL6. In the cecum, both glucose and fructose intake were associated with an increase in Il13, Ifnγ, and Tnfα mRNA and MLCK protein levels. To clarify the relationships between monosaccharides and barrier function, we measured the permeability of Caco-2 cell monolayers in response to IFNγ+TNFα in the presence of glucose or fructose. In vitro, IFNγ+TNFα-induced intestinal permeability increase was less pronounced in response to fructose than glucose. Mice treated with glucose showed an enrichment of Lachnospiracae and Desulfovibrionaceae while the fructose increased relative abundance of Lactobacillaceae. Correlations between pro-inflammatory cytokine gene expression and bacterial abundance highlighted the potential role of members of Desulfovibrio and Lachnospiraceae NK4A136 group genera in the inflammation observed in response to glucose intake. The increase in intestinal inflammation and circulating levels of IL6 in response to fructose was observed in the absence of intestinal permeability modification, suggesting that the intestinal permeability alteration does not precede the onset of metabolic outcome (low-grade inflammation, hyperglycemia) associated with chronic fructose consumption. The data also highlight the deleterious effects of glucose on gut barrier function along the GI tract and suggest that Desulfovibrionaceae and Lachnospiraceae play a key role in the onset of GI inflammation in response to glucose.
GATE LOCATION CHANGING: AN OPTIMIZATION TECHNIQUE FOR QUANTUM CIRCUITS

During the physical design process, the second process of the quantum circuit design flow, using some optimization techniques after layout generation might be useful to improve the metrics or meet the design constraints. Focusing on this issue, this paper proposes an optimization technique using gate location changing to improve the latency of quantum circuits. The proposed technique uses layout and scheduling information to find critical paths and improve their latency by changing locations of the gates on the critical paths. Experimental results show that the proposed technique decreases the latency of quantum circuits up to 26% for the attempted benchmarks.
