Articulating Os Intermetatarsium with painful ganglion cyst
Authors: Yaacoub Celestie , Kanj Ahmad , Eljebai Malak , Rouhana Georges , Kanj Ali
Published: May 2021

Objective: Sesamoid and accessory bones are commonly found in the foot and ankle with varying incidence. The Os intermetatarsium, located between the medial cuneiform and the base of the first and second metatarsal, occurs rarely and is frequently asymptomatic. Few symptomatic cases of this condition are reported in the literature.  The development of synovial ganglion cyst over an os intermetatarsium is a more occasional finding not clearly reported in the literature.

Case: Here we report the case of a 22 year old female presenting with pain and localized swelling in the dorsum of the midfoot who was found to have a ganglion cyst emerging from an articulating os intermetatarsium.

Conclusion: Although not a common entity, an Os intermetarsium, with its associated complications, can be one of the causes of dorsal foot pain.
BIM Adoption Issues in Infrastructure Construction Projects: Analysis and Solutions
Authors: Pidgeon Andrew , Dawood Nashwan
Published: May 2021

The objective of this paper is to assess and outline both the value and inefficiencies of Building Information Modelling (BIM) within Construction Infrastructure projects, and to provide a comparative and conclusive analysis via the underpinning academic literature and industrial reporting respectively. Further, semi-structured interviews were undertaken with a range of industry experts to add greater evidence at the application and execution stage, leading onto the proposal of a framework solution to gain advantage due to the implementation of BIM and counter some of the outlined inefficiencies and issues raised.
The aims and objectives of the research study were to develop a methodology that brings to the forefront issues with the adoption of BIM, and to propose a framework in order to provide clarity on resolving these issues to gain an advantage. The methodology consists of four parts which are:
1) Undertaking a systematic literature review of academic and a critical review of industrial literature
2) Analysing, contesting and supporting literature by undertaking a data collection exercise with a range of industry experts who are delivering construction projects and in particular infrastructure via BIM
3) Providing a comparative analysis between data collection, academic and industrial literature in a holistic format
4) Proposing a framework focused on countering the disadvantages and inefficiencies in the adoption of BIM.
There is also evidence of a disconnect due to both the overwhelming nature of BIM (acronyms, competing standards and technology) in that people are unsure what to implement and when, with a lack of objective focus on what the goals and advantages at a project level. The research concludes with a comparative synthesis of results and by outlining a framework solution focused on applying objective focus as part of the application process and requirements, supporting goal attainment and appropriate/agreed measurements of BIM.

Authors: Adediwura, Alaba Adeyemi  , Ajayi, Oyedokun Samuel
Published: May 2021

The study developed a scale for measuring assessment literacy of university teachers and determined the validity and reliability of the scale. This is with a view of improving university teachers’ assessment literacy. The study adopted the survey design. The population comprised all lecturers working in universities within Osun State. The sample consisted of 549 university teachers that were not in training position (lecturer II and above) from different disciplines selected using convenient sampling technique in all the eight accredited universities within Osun state. The study made use of three instruments namely; University Teachers Assessment Literacy Scale (UTALS), Teacher Self-Efficacy Scale (TSES) and Teacher Burnout Scale (TBS). The results showed that the 60- item UTALS was reduced to 43 items after the psychometric procedure of item retention and deletion were applied. Scree plot and eigen value methods showed that the final UTALS construct validity had seven factors of university teachers’ assessment literacy that accounted for 86.46% of the total scale variance and it significantly converge and diverge with the Teacher Efficacy Scale (r = 0.75) and Teacher Burnout Scale (0.52) respectively. The internal consistency reliability of the scale was 0.96 (Guttman), 0.90 (Cronbach), and 0.96 (Spearman). The study concluded that the university teacher’s assessment literacy scale developed in this study had adequate psychometric characteristics and is suitable for measuring assessment literacy of university teachers in Osun State. It was therefore recommended that the University Teacher’s Assessment Literacy Scale be adopted by institutions of higher learning for the assessment of new and old academic staff members’ assessment competency in order to help in the improvement of assessment standard of the institutions

Published: May 2021

Biocomposite materials have revolutionized the engineering field, predominantly in manufacturing applications, where these materials were widely used as an alternative to the metal-based structural body or component. Since conventional materials have caused various pollution problems to the ecosystem, innovative efforts have been taken to develop the based product on natural materials composites but presently are not fully explored yet. Most issues raised are due to the lack of expertise in addressing some of the problems and constraints related to preparing feedstock materials involved in the injection moulding technique. The injectability process of the biocomposite material significantly depends on the early stage of feedstock preparation. The preparation steps should be considering the detailed characterization of the composite material, the effectiveness of the mixing method, the identification of the feedstock's flowability properties, and the appropriate processing parameters used. This review manuscript has a significant contribution to researchers interested in furthering the application of biocomposite-based materials, particularly in plastics injection moulding technology for manufacturing and processing engineering.

Authors: Rahman Zillur , Ali M. Zulfikar , Harun-Or-Roshid  , Ullah Mohammad Safi
Published: May 2021

In this manuscript, the space-time fractional Equal-width (s-tfEW) and the space-time fractional Wazwaz-Benjamin-Bona-Mahony (s-tfWBBM) models have been investigated which are frequently arises in nonlinear optics, solid states, fluid mechanics and shallow water. Jacobi elliptic function expansion integral technique has been used to build more innovative exact solutions of the s-tfEW and s-tfWBBM nonlinear partial models. In this research, fractional beta-derivatives are applied to convert the partial models to ordinary models. Several types of solutions have been derived for the models and performed some new solitary wave phenomena. The derived solutions have been presented in the form of Jacobi elliptic functions initially. Persevering different conditions on a parameter, we have achieved hyperbolic and trigonometric functions solutions from the Jacobi elliptic function solutions. Besides the scientific derivation of the analytical findings, the results have been illustrated graphically for clear identification of the dynamical properties. It is noticeable that the integral scheme is simplest, conventional and convenient in handling many nonlinear models arising in applied mathematics and the applied physics to derive diverse structural precise solutions.

Published: May 2021

In this paper, operational amplifier circuit is designed using model parameters of high-k FinFET in 22nm technology. The conventional design expressions for MOSFET based OPAMP design are fine tuned to design FinFET based OPAMP. The OPAMP design is suitable for use as sub circuit in ADC design as it supports low voltage, high speed and low power dissipation. The transistor geometries are identified so as to achieve high performance and energy efficient OPAMP. Schematic capture is carried out using Cadence tool. From the simulation studies, the designed OPAMP has a unity gain bandwidth of 100 GHz and slew rate is equal to 1V/μS. The maximum power dissipation of differential amplifier circuit is 800nW and hence suitable for all low power analog and digital circuits.
Comparison of the Satellite Attitude Control System Design using the H∞ Method and H∞/MLI with Pole Allocation Considering the Parametric Uncertainty
Authors: DE SOUZA ALAIN , DE SOUZA LUIZ C. G.
Published: May 2021

This paper presents the comparison of the Attitude Control System (ACS) design for a rigid-flexible satellite with two vibrations mode, using the traditional H∞method and the H∞/LMI with pole allocation considering the parametric uncertainty. In the ACS design is important take into account the influence of thestructure’s flexibility, since they can interact with the satellite rigid motion, mainly, during translational and/or rotational manoeuvrer, damaging the ACS. Usually the mathematics model obtained from the linearization and/or reduction of the rigid flexible model loses information about the flexible dynamical behaviour and introduces some uncertainty. The satellite model is represented by a flexible beam connected to a central rigid hub considering a setof parametric uncertainties. Simulations results have shown that the control law designed by the H∞/LMI method has better performance and it is more robust than H∞method since the first was able to support the action of the uncertainty perturbation and to control the rigid flexible satellite attitude and suppressing vibrations.

Published: May 2021

Der Beitrag handelt von der computergestützten Sensitivitätsanalyse, mit welcher eine systematische Bewertung der Empfindlichkeit von Antwortgrößen eines statischen Systems bei variierenden Modellparametern möglich ist. Konkret wird gezeigt, wie zur Berechnung von Sensitivitäten die Technik der Einflusslinien verallgemeinert werden kann. Die vorgeschlagene Generalisierung ermöglicht eine Erweiterung des klassischen Ansatzes für verschiedenste Systemantwortgrößen, Parameter und Strukturtypen und vereint somit numerische Methoden der Sensitivitätsanalyse mit klassischem Ingenieurverständnis bezüglich Einflusslinien. Der Aufsatz gewährt Einblicke in die theoretischen Hintergründe des Ansatzes und zeigt auf, wie die Ergebnisse graphisch aufbereitet werden können, um schnell und zielgerichtet wichtige Parameter hinsichtlich der betrachteten Systemantwortgröße zu identifizieren. Somit eignet sich die Methode als Hilfsmittel im Rahmen von Bemessung und Sicherheitsbeurteilung. Hierfür wird eine Analyse- und Entscheidungskette vorgeschlagen, welche dabei helfen soll, relevante Systemempfindlichkeiten zu identifizieren und beurteilen.

Oedometer tests - an aid in determination of the geological
load history?
Authors: Thorsen Grete
Published: May 2021

The paper describes the results of oedometer tests carried out with samples from
Eemian fresh-water deposits and the methods used to determine the preconsolidation pressure from the test results. The influence of creep in the material on
the apparent preconsolidation pressure is estimated from a model set up by Moust
Jacobsen in 1992. The test results do not show any significant difference in the
determined values of the overconsolidation ratio (OCR) for the samples from
Hollerup and SolsØ, east and west of the main stationary line for the last ice sheet
in Weichselian, respectively. The results, however, te11 nothing about the kind of
actions, which has caused the overconsolidation. The determined OCR-values
might be due to previous ice caps but a big difference in the two values from Solso
indicates a considerable influence from other actions. The sediments from Hollerup
and SolsØ are not identical, and the effect of temperature, chemical and biological
processes on the apparent preconsolidation pressure has not been evaluated.
Modeling Cogeneration System in Shallow Geothermal Installations
Authors: Bottazzi Leticia , Armenta-Déu* Carlos
Published: May 2021

This paper presents a theoretical modeling of a cogeneration system using multiple heat exchangers and thermoelectric generator. The modeled system, designed for shallow geothermal energy, is a closed piping unit containing water as heat transfer fluid that circulates through a closed loop releasing thermal energy at the surface for heating and sanitary hot water. In addition, a Peltier cells array is attached to the piping system to generate electricity, thus the system is self-sufficient in terms of electric energy. This system helps in alleviating resource scarcity, achieves reduction in pollutant emissions, saves energy and creates sustainable environment for housing developments.

Published: May 2021

Growing global water stress caused by the combined effects of growing populations, increasing economic development, and climate change elevates the importance of managing and allocating water resources in ways that are economically efficient and that account for interdependencies between food production, energy generation, and water networks—often referred to as the “food-energy-water (FEW) nexus.” To support these objectives, this report outlines a replicable hydro-economic methodology for assessing the value of water resources in alternative uses across the FEW nexus–including for agriculture, energy production, and human consumption—and maximizing the benefits of these resources through optimization analysis. The report’s goal is to define the core elements of an integrated systems-based modeling approach that is generalizable, flexible, and geographically portable for a range of FEW nexus applications. The report includes a detailed conceptual framework for assessing the economic value of water across the FEW nexus and a modeling framework that explicitly represents the connections and feedbacks between hydrologic systems (e.g., river and stream networks) and economic systems (e.g., food and energy production). The modeling components are described with examples from existing studies and applications. The report concludes with a discussion of current limitations and potential extensions of the hydro-economic methodology.

ABSTRACT:There is a possibility of developing neovascular glaucoma in ischemic type of retinal vein occlusion. Purpose of the study is to determine the role of anti VEGF agent bevacizumab for prevention of neovascular glaucoma in ischemic type of retinal vein occlusion.METHOD: It was a retrospective study of 34 cases with unilateral central retinal vein occlusion. All of them were treated with intra vitreous Bevacizumab for management of associated macular edema. Primary outcome was to study development of neovascular glaucoma in these cases.RESULTS: Thirty four cases were selected with retinal vein occlusion. Seventeen cases were of non ischemic type and remaining 17 were of ischemic type vein occlusion. During a follow up period of two years non ischemic group was given on average 8 bevacizumab injection. Only one of these non ischemic eyes developed neo vessels of optic disc but neo vascular glaucoma did not develop. In case of ischemic group during follow up period of two years a mean of 6 bevacizumab injections were given. In this ischemic group 2 cases developed iris neovesseles and 3 cases developed retinal neovesseles. Out of these, three eyes progressed to neovascular glaucoma.CONCLUSION: Bevacizumab treatment of macular edema for ischemic central retinal vein occlusion does not prevent neovascular glaucoma.

Migration is generally defined as a period of time or permanent settlement of people by moving from a place of origin to another place. Throughout history, humanity has migrated due to natural disasters, religion, poverty, wars and this migration has caused urbanization with population growth. With the increase in population, irregular and excessive migration, decrease in resources, unplanned urbanization, infrastructure problems, wastewater lines, drinking water lines, rainwater collection lines, power lines, and natural gas pipelines cannot be delivered to desired places, traffic, and excessive waste generation increased. Therefore environmental pollution and health problems arise in cities. Today, due to the adverse environmental impact of all these, people have become more sensitive and have tended to find solutions to the problem with areas such as sustainable structures, recycling, and reuse of waste. In this study, the studies and gains made with the recycling aggregate used are evaluated in order to produce solutions for environmental pollution caused by the construction sector.

Visa traçar as grandes linhas desse quadro e abordar, em detalhes, a implementação da Pauad de 2003. Esta política representou uma mudança de paradigma na atenção a pessoas com problemas decorrentes do consumo de substâncias psicoativas, não só porque deslocou o primado da abstinência, mas também porque traz implícito, em sua concepção, o desafio de restituir os direitos de cidadania a estas pessoas. Visa também analisar as práticas cotidianas de sua implementação, refletir sobre as possibilidades e os limites desta política, de assegurar ou restituir o acesso destas pessoas aos seus direitos fundamentais.

Resonant Chains of Exoplanets: Libration Centers for Three-body Angles
Authors: Siegel Jared C. , Fabrycky Daniel
Published: May 2021

Resonant planetary systems contain at least one planet pair with orbital periods librating at a near-integer ratio (2/1, 3/2, 4/3, etc.) and are a natural outcome of standard planetary formation theories. Systems with multiple adjacent resonant pairs are known as resonant chains and can exhibit three-body resonances—characterized by a critical three-body angle. Here we study three-body angles as a diagnostic of resonant chains through tidally damped N-body integrations. For each combination of the 2:1, 3:2, 4:3, and 5:4 mean motion resonances (the most common resonances in the known resonant chains), we characterize the three-body angle equilibria for several mass schemes, migration timescales, and initial separations. We find that under our formulation of the three-body angle, which does not reduce coefficients, 180° is the preferred libration center, and libration centers shifted away from 180° are associated with nonadjacent resonances. We then relate these angles to observables, by applying our general results to two transiting systems: Kepler-60 and Kepler-223. For these systems, we compare N-body models of the three-body angle to the zeroth order in e approximation accessible via transit phases, used in previous publications. In both cases, we find the three-body angle during the Kepler observing window is not necessarily indicative of the long-term oscillations and stress the role of dynamical models in investigating three-body angles. We anticipate our results will provide a useful diagnostic in the analysis of resonant chains.

We explore the connection between the kinematics, structures and stellar populations of massive galaxies at 0.6 < z < 1.0 using the fundamental plane (FP). Combining stellar kinematic data from the Large Early Galaxy Astrophysics Census (LEGA-C) survey with structural parameters measured from deep Hubble Space Telescope imaging, we obtain a sample of 1419 massive (

We find that quiescent and star-forming galaxies occupy the parameter space of the g-band FP differently and thus have different distributions in the dynamical mass-to-light ratio (M

A supermassive black hole (SMBH) ejected from the potential well of its host galaxy via gravitational wave recoil carries important information about the mass ratio and spin alignment of the pre-merger SMBH binary. Such a recoiling SMBH may be detectable as an active galactic nucleus (AGN) broad-line region offset by up to 10 kpc from a disturbed host galaxy. We describe a novel methodology using forward modeling with The Tractor to search for such offset AGNs in a sample of 5493 optically variable AGNs detected with the Zwicky Transient Facility (ZTF). We present the discovery of nine AGNs that may be spatially offset from their host galaxies and are candidates for recoiling SMBHs. Five of these offset AGNs exhibit double-peaked broad Balmer lines, which may have arisen from unobscured accretion disk emission, and four show radio emission indicative of a relativistic jet. The fraction of double-peaked emitters in our spatially offset AGN sample is significantly larger than the 16% double-peaked emitter fraction observed for ZTF AGNs overall. In our sample of variable AGNs we also identified 52 merging galaxies, including a new spectroscopically confirmed dual AGN. Finally, we detected the dramatic rebrightening of SDSS 1133, a previously discovered variable object and recoiling SMBH candidate, in ZTF. The flare was accompanied by the reemergence of strong P Cygni line features, indicating that SDSS 1133 may be an outbursting luminous blue variable star.
3D Convection-resolving Model of Temperate, Tidally Locked Exoplanets
Authors: Lefèvre Maxence , Turbet Martin , Pierrehumbert Raymond
Published: May 2021

A large fraction of known terrestrial-size exoplanets located in the habitable zone of M-dwarfs are expected to be tidally locked. Numerous efforts have been conducted to study the climate of such planets, using in particular 3D global climate models (GCMs). One of the biggest challenges in simulating such an extreme environment is to properly represent the effects of sub-grid convection. Most GCMs use either a simplistic convective-adjustment parameterization or sophisticated (e.g., mass flux scheme) Earth-tuned parameterizations. One way to improve the representation of convection is to study convection using numerical convection-resolving models (CRMs), with a fine spatial resolution. In this study, we developed a CRM coupling the non-hydrostatic dynamical core Advanced Research Weather-Weather Research and Forecast model with the radiative transfer and cloud/precipitation models of the Laboratoire de Météorologie Dynamique generic climate model to study convection and clouds on tidally locked planets, with a focus on Proxima b. Simulations were performed for a set of three surface temperatures (corresponding to three different incident fluxes) and two rotation rates, assuming an Earth-like atmosphere. The main result of our study is that while we recover the prediction of GCMs that (low-altitude) cloud albedo increases with increasing stellar flux, the cloud feedback is much weaker due to transient aggregation of convection leading to low partial cloud cover.
Pebble Trapping in Vortices: Three-dimensional Simulations
Authors: Raettig Natalie , Lyra Wladimir , Klahr Hubert
Published: May 2021

Disk vortices have been heralded as promising routes for planet formation due to their ability to trap significant amounts of pebbles. While the gas motions and trapping properties of two-dimensional vortices have been studied in enough detail in the literature, pebble trapping in three dimensions has received less attention, due to the higher computational demand. Here we use the Pencil Code to study 3D vortices generated by convective overstability and the trapping of solids within them. The gas is unstratified whereas the pebbles settle to the midplane due to vertical gravity. We find that for pebbles of normalized friction times of

, the vortex column in the midplane is strongly perturbed. Yet when the initial dust-to-gas ratio is decreased the vortices remain stable and function as efficient pebble traps. Streaming instability is triggered even for the lowest dust-to-gas ratio (

) we assumed, showing a path for planetesimal formation in vortex cores from even extremely subsolar metallicity. To estimate if the reached overdensities can be held together solely by their own gravity we estimate the Roche density at different radii. Depending on disk model and radial location of the pebble clump we do reach concentrations higher than the Roche density. We infer that if self-gravity was included for the pebbles then gravitational collapse would likely occur.
XMM-Newton X-Ray Observations of the Unusual Wolf–Rayet Star WR 66

Published: May 2021

We summarize results of an XMM-Newton X-ray observation of the WN8h-type Wolf–Rayet star WR 66 which shows unusual 3.5–4.1 hr optical variations. One possible explanation is a compact companion (cc) which, if present, could give rise to luminous X-ray emission. WR 66 was marginally detected and its inferred X-ray luminosity (L

x
) is orders of magnitude below that expected from wind accretion onto a neutron star, but is comparable to that of the WN8h stars WR 16 and WR 124. If luminous X-ray emission from an accreting WR+cc system is present then it is absorbed and escapes detection. Other explanations of the faintly detected X-ray emission of WN8h stars are not ruled out.
