Siontorou Aquatic Modeling : An Interplay between Scales

This paper presents an integrated knowledge-based approach to multi-scale modeling of aquatic systems, with a view to enhancing predictive power and aiding environmental management and policy-making. The basic phases of this approach have been exemplified in the case of a bay in Saronicos Gulf (Attiki, Greece). The results showed a significant problem with rising phytoplankton blooms linked to excessive microbial growth, arisen mostly due to increased nitrogen inflows; therefore, the nitrification/denitrification processes of the benthic and water column sub-systems have provided the quality variables to be monitored for assessing environmental status. It is thereby demonstrated that the proposed approach facilitates modeling choices and implementation option decisions, while it provides substantial support for knowledge and experience capitalization in long-term water management. Keywords—Aquatic ecosystem, integrated modeling, multi-scale modeling, ontological platform.

CANOLA YIELD FORMATION UNDER DIFFERENT SEEDING METHODS AND SEEDING RATES

The aim of the present investigation was to study the effect of seeding methods and seeding rates on yielding ability and yield structure of Brassica napus and Brassica campestris (canola). For this purpose, four separate field experiments were conducted at the Agricultural Experiment and Research Center, Faculty of Agriculture, Cairo University during 2002/2003 and 2003/2004 winter seasons. The experiments were carried out in a split plot design with 4 replications. The main plots were randomly distributed by three seeding methods (broadcasting, drilling in rows 25 cm and 50 cm apart). The sub-plots were devoted to three seeding rates of 1, 2 and 3Kg/fad at each seeding method. Of the main effects on both species, combined data over the two seasons revealed that seeding methods had significant effect on seed yield/fad as well as yield/plant(g) and its contributing traits with some exceptions, while seeding rate effects were only significant for yield/plant(g) and its components in addition to seed oil% of B. campestris only. Considering the interaction between the two factors of study, seeding method appeared to be the major one affecting the canola productivity under the present conditions. Drill seeding of both species either in 25 or 50 cm row spacing at any seeding rate produced higher yield/fad than the broadcasting. Numerically highest yield/fad of both species was produced from drilling at 25 cm row spacing combined with 3 Kg/fad seeding rate. Seed yield/plant(g) and all of its components were significantly affected by the interaction. Yield/plant(g) and siliquae/plant as well as yield and siliquae per main, primary and secondary branches in addition to seed index exhibited linear decrease as seeding rates increased, and this was true for almost all seeding methods. High values of these traits were recorded at lower (1 Kg/fad) seeding rate at any seeding method. The interaction had no significant effect on seed oil % for both species. Yield analysis of individual plant showed that the differences in total yield contribution from the main and lateral branches were mostly due to the species. Brassica. napus plants carrying on average more than 90% of total yield/plant(g) on the main and primary branches, while the contribution of secondary branches varied from 0.01 to 9.4% taking into account seeding methods and rates. In contrast, the contribution of secondary branches of B. campestris accounted for 43.5% as a general mean over the two factors of study. The results overall suggest that drill seeding at 25 cm row spacing combined with seeding rate of 3 Kg/fad should be used for production of both B. napus and B. campestris
Resting-state connectivity and its association with cognitive performance, educational attainment, and household income in UK Biobank (N = 3,950)

Cognitive ability is an important predictor of lifelong physical and mental well-being and its impairments are associated with many psychiatric disorders. Higher cognitive ability is also associated with greater educational attainment and increased household income. Understanding neural mechanisms underlying cognitive ability is therefore of crucial importance for determining the nature of these associations. In the current study, we examined the spontaneous activity of the brain at rest to investigate its relationships with not only cognitive ability, but also educational attainment and household income. We used a large sample of resting-state neuroimaging data from UK Biobank (N=3,950). Firstly, analysis at the whole-brain level showed that connections involving the default mode network (DMN), fronto-parietal network (FPN) and cingulo-opercular network (CON) were significantly positively associated with levels of cognitive performance assessed by a verbal-numerical reasoning test (standardised β ranged from 0.054 to 0.097). Connections associated with higher levels of cognitive performance were also significantly positively associated with educational attainment (r=0.48, N=4,160) and household income (r=0.38, N=3,793). Further, analysis on the coupling of functional networks showed that better cognitive performance was associated with more positive DMN-CON connections, decreased cross-hemisphere connections between homotopic network in CON and FPN, and stronger CON-FPN connections (absolute β ranged from 0.034 to 0.063). The present study finds that variation in brain resting state functional connectivity associated with individual differences in cognitive ability, largely involving DMN and lateral prefrontal networks. Additionally, we provide further evidence of shared neural associations of cognitive ability, educational attainment, and household income.
Requirements and Concept for a Self-organizing Plug&Fly Avionics Platform

Today’s avionics platforms are statically configured and certified. Significant effort reduction would be possible if avionics components were self-configuring. Moreover, a dynamic state monitoring and adaptation would enable increased reliability and resource reduction. In addition, a self-organized redundant instantiation of software and system management mechanisms would simplify system development and integration. We name such a self-organizing platform Plug&Fly Avionics (PAFA). The research project PAFA-ONE is carried out with the goals to demonstrate the technical feasibility of PAFA and to derive a potential roadmap to a safe and certified use of PAFA. As an avionics platform, PAFA must follow the requirements-driven development process of ARP 4754. With this paper we define 11 high-level and 38 low-level requirements for a PAFA platform, in such a way that the requirements do not prescribe a solution, are technology- independent and are in line with major avionics’ regulations, such as DO-178. One challenge is that an avionics platform on its own cannot be certified. We respond to this challenge by adopting the incremental acceptance strategy used for Integrated Modular Avionics (IMA) as described in DO-297. From the requirements we derive a concept that allows self-organization properties on IMA technology. Partitions are assigned such that complex algorithms for self-organization can reside in a partition with a low Design Assurance Level (DAL). Moreover, a virtual qualification authority partition is presented that mimics qualification tasks during runtime and can prevent that all configurations have to be validated a priori.
Fat talk in online discourse. A comparison of pro-anorexia and body positivity on social media.

This study will compare two online communities; pro-anorexia and body positivity through a retrieval of posts tagged with the hashtags #thinspo (‘thin inspiration’) and #bopo (‘body positivity’) respectively. Two corpora of 120 posts per community were comprised and then processed in AntConc with the aid of a corpus linguistic approach. The data was then analysed with the aid of Arroyo and Harwood’s categorisation of ‘fat talk’ (2014), a typically female type of discourse often containing self-derogatory body commentary, to identify linguistic markers of the two groups. The results showed that body positive posts contained more we-talk, positive affect in terms of affirmation of self and others, as well as describing change of their relationships to their bodies rather than an external change of their bodies. Pro-anorexia discourse showed a general pattern of expressing more negative affect (disappointment, fear, disgust) as well as making negative self-evaluations. Unlike previous research, hardly any ‘we-talk’ was found the pro-anorexia discourse, indicating a lack of community.
Teachers on the Market : A Typology of Teachers ’ Philosophy , Mission , Vision , and Values WCER Working Paper No . 2019-2 March 2019

This study develops, validates, and applies a typology of teachers using labor market data. We construct our typology by applying a correlated topic model to 17,000 personal statements teachers submitted as part of their applications to open positions in Wisconsin public schools. We identify seven types of teachers active on the labor market: Inclusivists, Idealists, Nurturers, Generalists, Classroom Experts, Guides, and External Experts. Using a combination of quantitative and qualitative methods, we explore trends within and among types as well as demographic relationships and labor market behaviors. This research provides novel insights into the philosophies, mission, vision, and values of teachers; links these characteristics to teachers’ job market preferences; and provides a sound psychometric foundation for these measures of teacher type to be applied in subsequent research.
Biliary Tract Cancers: Treatment Updates and Future Directions in the Era of Precision Medicine and Immuno-Oncology

The effective management of biliary tract cancers (BTCs) has been hampered by limited options for systemic therapy. In recent years, the focus on precision medicine has made technologies such as next-generation sequencing (NGS) accessible to clinicians to identify targetable mutations in BTCs in tumor tissue (primarily) as well as blood, and to treat them with targeted therapies when possible. It has also expanded our understanding of functional pathways associated with genetic alterations and opened doors for identifying novel targets for treatment. Recent advances in the precision medicine approach allowed us to identify new molecular markers in BTCs, such as epigenetic changes (methylation and histone modification) and non-DNA markers such as messenger RNA, microRNA, and long non-coding RNA. It also made detecting these markers from non-traditional sources such as blood, urine, bile, and cytology (from fine-needle aspiration and biliary brushings) possible. As these tests become more accessible, we can see the integration of different molecular markers from all available sources to aid physicians in diagnosing, assessing prognosis, predicting tumor response, and screening BTCs. Currently, there are a handful of approved targeted therapies and only one class of immunotherapy agents (immune checkpoint inhibitors or ICIs) to treat BTCs. Early success with new targets, vascular endothelial growth factor receptor (VEGFR), HER2, protein kinase receptor, and Dickkopf-1 (DKK1); new drugs for known targets, fibroblast growth factor receptors (FGFRs) such as futabatinib, derazantinib, and erdafitinib; and ICIs such as durvalumab and tremelimumab is encouraging. Novel immunotherapy agents such as bispecific antibodies (bintrafusp alfa), arginase inhibitors, vaccines, and cellular therapy (chimeric antigen receptor—T cell or CAR-T, natural killer cells, tumor-infiltrating lymphocytes) have the potential to improve outcomes of BTCs in the coming years.
An interpolation problem for coefficients of ^{∞} functions

HI denotes the space of all bounded functions g on the unit circle whose Fourier coefficients g(n) are zero for all negative n. It is known that, if {nfk},O is a sequence of nonnegative integers with nk+l > (1 +5)nk for all k, and if Z0-0 IVk 12 < OO, then there is a functiong in HI with A(nk)=vk for all k. Previous proofs of this fact have not indicated how to construct such HI functions. This paper contains a simple, direct construction of such functions. The construction depends on properties of some polynomials similar to those introduced by Shapiro and Rudin. There is also a connection with a type of Riesz product studied by Salem and Zygmund. We shall present the construction in ? 1 and discuss its relation to other results in ? 2. First we recall some notation. For p < xo, LI denotes the space of all measurable functions on the unit circle whose p'th power is integrable; as usual, functions are identified if they agree almost everywhere. L' denotes the space of all essentially bounded measurable functions on the unit circle; for g in L', 1ig Ioo denotes the essential supremum of Igl. The Fourier coefficients of an LI function g are defined by g(n) = f g(eiO)e-no dO (n = 0, 41, 42** Finally, H' is taken to be the space of all g in L' which have g(n) =0 for all n<O. It can be shown [4, p. 39] or [5, Theorem 3.12, p. 88] that this version of H' is isomorphic to the space of all bounded analytic functions in the open unit disc, but this fact will not be used here. 1. The construction depends on the fact that, for complex numbers a, b, and v, (1) la + vbI2 + lb ea12 = (1 + IV12)(la12 + lb12). Received by the editors March 13, 1972.

Coupled jet-disk model for Sagittarius A*: explaining the flat-spectrum radio core with GRMHD simulations of jets

Context. The supermassive black hole in the center of the Milky Way, Sgr A*, displays a nearly flat radio spectrum that is typical for jets in active galactic nuclei. Indeed, time-dependent magnetized models of radiatively ineffi cient accretion flows (RIAFs), which are commonly used to explain the millimeter, near-infrared, and X-ray emission of Sgr A*, often also produce jet-like outflo ws. However, the emission from these models has so far failed to reproduce the flat radio spectrum. Aims. We investigate whether current accretion simulations can produce the compact flat spectrum emission by simply using a different prescription for the heating of the radiating particl es in the jet. Methods. We studied the radiative properties of accretion flows onto a black hole produced in time-dependent general-relativistic magnetohydrodynamic (GRMHD) simulations. A crucial free parameter in these models has always been the electron temperature, and here we allowed for variations in the proton-to-electron temperature ratios in the jet and disk. Results. We found that the flat spectrum is readily reproduced by a stan dard GRMHD model if one has an almost isothermal jet coupled to a two-temperature accretion flow. The low-frequency radio emission comes from the outflowing sheath of matter sur rounding the strongly magnetized nearly empty jet. The model is consistent with the radio sizes and spectrum of Sgr A*. Conclusions. Hence, GRMHD models of accreting black holes can in principle naturally reproduce jets that match observed characteristics. For Sgr A* the model fit to the spectrum predicts higher mass-accretion rates when a jet is included than without a jet. Hence, the impact of the recently discovered G2 cloud that is expected to be accreted onto Sgr A* might be less severe than currently thought.
Bisexual Prejudice Among Lesbian and Gay People: Examining the Roles of Gender and Perceived Sexual Orientation

Research on dynamics within communities of sexual and gender minorities is scant, despite reports that people experience prejudice within lesbian, gay, bisexual, transgender, and queer (LGBTQ) spaces. The present research examined dynamics within LGBTQ communities and used gender as a lens of understanding bisexual prejudice among lesbian women and gay men. In two online studies with lesbian and gay participants (NStudy1 = 120; NStudy2 = 165), we randomly assigned participants to reflect on lesbian and gay people’s attitudes toward bisexual women or bisexual men. In each study, we evaluated lesbian and gay people’s perceptions of identity instability, sexual irresponsibility, and interpersonal hostility. In Study 2, we proposed that beliefs about bisexual people’s attraction (to men or to women) serve as a mechanism of bisexual prejudice among lesbian and gay people. We found that people perceived bisexual women and men as being more sexually attracted to men than they are to women, which helps to explain why some lesbian women reported more negative attitudes toward bisexual women than gay men did. Moreover, we tested whether lesbian and gay people’s identification with their ingroup, as well as their experiences with dating bisexuals, exacerbated negative perceptions of bisexuals. Taken together, these studies offer implications for reducing bisexual health disparities via improving dynamics within LGBTQ communities.
The Rho 3 and Rho 4 small GTPases interact functionally with Wsc 1 p , a cell surface sensor of the protein kinase C cell-integrity pathway in Saccharomyces cerevisiae

Received 26 May 2005 Revised 11 November 2005 Accepted 23 November 2005 Rgd1, a GTPase-activating protein, is the only known negative regulator of the Rho3 and Rho4 small GTPases in the yeastSaccharomyces cerevisiae. Rho3p and Rho4p are involved in regulating cell polarity by controlling polarized exocytosis. Co-inactivation of RGD1 and WSC1, which is a cell wall sensor-encoding gene, is lethal. Another plasma membrane sensor, Mid2p, is known to rescue the rgd1Dwsc1D synthetic lethality. It has been proposed that Wsc1p and Mid2p act upstream of the protein kinase C (PKC) pathway to function as mechanosensors of cell wall stress. Analysis of the synthetic lethal phenomenon revealed that production of activated Rho3p and Rho4p leads to lethality in wsc1D cells. Inactivation of RHO3 or RHO4 was able to rescue the rgd1Dwsc1D synthetic lethality, supporting the idea that the accumulation of GTP-bound Rho proteins, following loss of Rgd1p, is detrimental if the Wsc1 sensor is absent. In contrast, the genetic interaction between RGD1 and MID2 was not due to an accumulation of GTP-bound Rho proteins. It was proposed that simultaneous inactivation of RGD1 and WSC1 constitutively activates the PKC–mitogen-activated protein kinase (MAP kinase) pathway. Moreover, it was shown that the activity of this pathway was not involved in the synthetic lethal interaction, which suggests the existence of another mechanism. Consistent with this idea, it was found that perturbations in Rho3-mediated polarized exocytosis specifically impair the abundance and processing of Wsc1 and Mid2 proteins. Hence, it is proposed that Wsc1p participates in the regulation of a Rho3/4-dependent cellular mechanism, and that this is distinct from the role of Wsc1p in the PKC–MAP kinase pathway.
Study of Medicolegal Aspects of Burnt Cases Admitted to Burn Unit, Assiut university Hospitals: retrospective study

Background: In both developed and developing countries, burns remain a medical, psychological, and economic burden. In Egypt, burns are a serious issue when compared to heart disease, cancer, and traffic accidents. Objectives: Accordingly, this work was conducted to study the medico legal aspects of burnt cases admitted to Burn Unit in Assiut University Hospitals. Subjects and methods: A retrospectives study included 730 reports data which were collected from the records during the period from1 January 2017 to the end of December 2020.Data collected included; age, gender, residence, socioeconomic level, causes of burn, site of burn, duration of hospital stay of victims, fate of cases, and causes of death. Results: There was an increase in the percentage of number of burned male victims which represented (68.9%) than female patients. Most burnt patients were among the age groups of toddlers (1-3 years) and children (4-17 years) with a percentage of (34.2%& 26%) respectively. There was a significant increase of burnt cases in rural areas with a percentage of 64.9%. There was a significant increase of burnt cases among low/very low group with a percentage 59%. The commonest cause of burn injuries encountered in this study was scald (50.5%) followed by flame was followed by scald (42.2 %). Most injuries occurred at home with a percentage of (92.7%). The range of duration of hospital stay for the cases included in the study was 7 days. 84% of burnt cases included in the study are cured while 16% of burnt cases died due to sepsis (43.5%). Conclusion: Infants, toddlers and children are affected more with burns. Males are affected by burns more than females. The most common type of burns was due to scald. Proper preventive measures against burns should be taken in order to prevent burns particularly in children. Recommendations: Medicolegal reports should be attached to the medical report of the patients.
EXPERIMENTAL STUDIES ON MULTI-CYLINDER NATURAL GAS ENGINE FUELED WITH PRODUCER GAS

Biomass gasificationa thermo-chemical conversion process, with near zero net carbon emission has a significant potential to displace fossil fuel use especially in various modes of power generation. The current study presents the results from investigations carried out on a six-cylinder natural gas engine rated at 55.0 kW fueled using producer gas as a fuel. The peak load on the engine was 29 kW at 24 Deg BTDC ignition setting. At 29 kW, the pressure trace yielded a peak pressure of 35 atmospheres and the indicated power was 42 kW. A specific biomass consumption of 1.35 kg/kWh of electricity was recorded with brake thermal efficiency of 23% and an overall biomass to electricity efficiency of 18%. Measured exhaust composition without a catalytic converter revealed 0.22 g/MJ NOx, 0.017 g/MJ HC meeting the international specifications for stationary power generation systems, while CO was found to be 4.9 g/MJ which is higher than the norm.
Carbon Fibers

CARBON FIBERS, after a 40 year period of development and use in specialized applications, are now on the brink of broad commercialization. Their use is growing rapidly, fueled by significant price reductions during the 1990s and increasing availability. Changes in the performance/price ratio have resulted in the increased penetration of composites into applications formerly held by metals and has enabled their use in other applications previously not possible with existing materials. Additionally, market conditions increasingly favor designs for commercial products that are lighter, stronger, faster, and more fuel efficient—designs that are possible with carbon fibers. No longer relegated to aerospace, carbon fiber composites are now being adopted in fields such as automotive, civil infrastructure, offshore oil, and paper production.
