Authors: Guechi N , Ghaffor Y , Oukachbi S , Hamrioui B
Published: July 2021

Objectifs : Le but de notre étude était d’évaluer la séroprévalence ainsi que le risque de toxoplasmose aiguë chez des patients qui ont subi une transplantation rénale, hépatique ou une greffe de moelle osseuse.

Patients et méthode : Une étude prospective a été menée du  01 Janvier 1999 à Décembre 201.Les sérologies toxoplasmiques ont été réalisées à partir des  sérums de 888  patients (444 couples donneurs/receveurs)  au niveau du laboratoire de Parasitologie -Mycologie du CHU Mustapha d'Alger par la technique immunoenzymatique   ELISA (358  candidats à la transplantation rénale, 69  à la greffe de moelle osseuse, 17  à la transplantation hépatique).

Résultats: La séroprévalence globale  était de 54,5%.81 receveurs de transplantation rénale ont été transplantés et avaient des sérologies régulières de toxoplasmose :45 étaient séropositifs  et 36  séronégatifs avant la transplantation ; aucune toxoplasmose aiguë  n'a été   observée chez les 36 patients  séronégatif et aucune réactivation  chez les 45 autres  séropositifs après la transplantation .17  receveurs de   transplantation hépatique  ont  été transplantés  et avaient  des sérologies régulières de toxoplasmose:5 était  séropositifs  et 5  séronégatif avant la transplantation; aucune toxoplasmose aiguë  n'a été  observée chez les 5 patients séronégatifs et aucune réactivation chez les  5 autres séropositifs après la transplantation . Pour les greffés de moelle osseuse, pour des raisons pratiques, le suivi sérologique n’a pu être effectué.

Conclusion: La surveillance sérologique chez les transplantés reste nécessaire  surtout chez les séronégatifs. II est important de connaître la sérologie du receveur avant la transplantation et si possible celle du donneur afin d’interpréter plus facilement toute modification. Cette surveillance doit être très régulière pour permettre le diagnostic rapide d'une toxoplasmose évolutive.

Balancing Inclusion and Diversity with Upholding Free Speech Rights in Canadian Universities: Challenging but Feasible
Authors: Karimi Sirvan
Published: July 2021

The tension emanated from deeply polarized socio-cultural values has found its way into the Canadian university campuses. In their endeavour to strike a balance between promoting diversity, inclusion and respecting free speech, the Canadian higher educational institutions have encountered formidable challenges. Central to the contention revolving around the free speech debate is an assertion that institutional pressures for consolidating a culture of political correctness is believed to have the potential to curtail and stifle freedom of expression which has in turn triggered governmental intervention in certain Canadian provinces. The lack of a proper balance between the quest for promoting inclusion, diversity and free speech can in the long run undermine the socially vital mission of universities, and hence corroding the public trust in the higher educational institutions. Obviously, there is no single solution that can function as panacea to surmount theses pressing demands faced by the Canadian universities. However, it will be argued that the extension of constitutionally protected freedom of expression to the Canadian universities is not only geared to address the shortcomings of academic freedom, but it is also conducive to harmonizing the pursuit of promoting diversity and inclusion with upholding free speech principles.
How to Manage the Components of Financial Sustainability in Local Governments
Authors: Santis Serena , Incollingo Alberto , Citro Francesca
Published: July 2021

This study aims to evaluate three dimensions proposed by the IFAC (International Federation of Accountants) in relation to impact financial sustainability. These dimensions are service, revenue, and debt. In 2017 and 2018, a regression analysis was conducted for Italian local governments on the different components of financial sustainability. Based on goal-setting theory, and in combination with the ambition to pursue adequate good financial sustainability, significant results were demonstrated. It was seen that these local governments would have to maintain a good level of autonomy with current revenue. They would also need to control the quantity and quality of service in order to pursue financial sustainability. This study suggests practical implications for policymakers and the managerial class, and it seeks to identify methods to drive and keep financial sustainability under control. It also seeks to define current and future management strategies that focus on pursuing intergenerational equity in local governments.

SOLUTION OF A NON-HOMOGENEOUS LIAPUNOV'S EQUATION
SOME INEQUALITIES AMONG GENERALIZED DIVERGENCE MEASURES
Authors: TANEJA I. J. , PARDO L. , MENÉNDEZ M. L.
Published: July 2021

Burbea and Rao [3,4] and Sgarro [11] established an inequality between two famous divergence measures i.e., Jeffreys [6] invariant function ($J$-divergence) and Sibson's [13] information radius ($R$-divergence). Taneja [14,16] generalized both these divergences ($J$ and $R$) having two scalar parameters. In this paper, we have extended the inequality between the $R$ and $J$-divergences for two parametric cases. For one parametric generalizations of $R$ and $J$-divergences, the generalized inequalities are improved.
Hyperelastic models for the description
and simulation of rubber subjected to
large tensile loading
Authors: Jebur Q.H. , Jweeg M.J. , Al-Waily M. , Ahmad H.Y. , Resan K.K.
Published: July 2021

Purpose: Rubber is widely used in tires, mechanical parts, and user goods where elasticity
is necessary. Some essential features persist unsolved, primarily if they function in excessive
mechanical properties. It is required to study elastomeric Rubber's performance, which is
operational in high-level dynamic pressure and high tensile strength. These elastomeric aims
to increase stress breaking and preserve highly pressurised tensile strength.
Design/methodology/approach: The effects of carbon black polymer matrix on the
tensile feature of different Rubber have been numerically investigated in this research.
Rubber's material characteristics properties were measured using three different percentages
(80%, 90%and 100%) of carbon black filler parts per Hundreds Rubber (pphr).
Findings: This study found that the tensile strength and elongation are strengthened as the
carbon black filler proportion increases by 30%.
Practical implications: This research study experimental tests for Rubber within four
hyperelastic models: Ogden's Model, Mooney-Rivlin Model, Neo Hooke Model, Arruda-
Boyce Model obtain the parameters for the simulation of the material response using
the finite element method (FEM) for comparison purposes. These four models have been
extensively used in research within Rubber. The hyperelastic models have been utilised to
predict the tensile test curves—the accurate description and prediction of elastomer rubber
models. For four models, elastomeric material tensile data were used in the FEA package
of Abaqus. The relative percentage error was calculated when predicting fitness in selecting
the appropriate model—the accurate description and prediction of elastomer rubber
models. For four models, elastomeric material tensile data were used in the FEA package
of Abaqus. The relative percentage error was calculated when predicting fitness in selecting
the appropriate model. Numerical Ogden model results have shown that the relative fitness
error was the case with large strains are from 1% to 2.04%.
Originality/value: In contrast, other models estimate parameters with fitting errors from
2.3% to 49.45%. The four hyperelastic models were tensile test simulations conducted to verify the efficacy of the tensile test. The results show that experimental data for the uniaxial
test hyperelastic behaviour can be regenerated effectively as experiments. Ultimately, it
was found that Ogden's Model demonstrates better alignment with the test data than other
models.

Este trabalho discute os impactos in loco da atuação de egressos de Instituições de Ensino Superior (IES) brasileiras localizadas fora de grandes centros urbanos, tendo como estudo de caso o curso de Ciência da Computação do Instituto Federal do Ceará (IFCE) Campus Aracati. Nele é delineado o perfil dos egressos a partir do cruzamento de diversos indicadores: tipo e local de atuação profissional, faixa salarial, pós-graduação e formação extracurricular durante a graduação. É mostrado que, apesar da maioria dos egressos atuar na área de tecnologia com bons salários, houve um êxodo considerável dos egressos oriundos do município de formação e região para a capital Fortaleza-CE, o que coloca em questão a necessidade de novas e urgentes estratégias para desenvolvimento socioeconômico das regiões interioranas que abrigam IES.
Kritik als Aufgabe. Zum Kritikbegriff der Sozial- und Kulturwissenschaften
Authors: Adolf Marian
Published: July 2021

Kritik ist überall anzutreffen. Das liegt daran, dass Kritisieren zur Grundausstattung des Menschen gehört: dort wo gefühlt, gedacht und gehandelt wird ist immer auch Kritik. In aufgeklärten Gesellschaften, und solchen die sich dafür halten, ist Kritik ein sich selbst empfehlender Begriff. Das gilt insbesondere für die Wissenschaft, in der Kritik als wesentlicher Motor der Erkenntnis gilt. Doch gerade angesichts der Allgegenwart und zugeschriebenen Tugendhaftigkeit des Kritikbegriffes tut eine Begriffsklärung not. Denn nicht alles, was sich als Kritik ausgibt, kann als solche gelten und nicht immer erreicht Kritik jene Qualität, die sie eigentlich rechtfertigt. Dieser Beitrag versteht sich daher als Vorarbeit für das hier behandelte Thema der Kritik in/an der Kommunikationswissenschaft und beleuchtet Kritik in ihrer ideengeschichtlichen, gesellschaftlichen und wissenschaftlichen Entwicklung. Behandelt werden ausgewählte Kritikbegriffe sowie klassische Debatten betreffend die Funktion und Rolle von Kritik, insbesondere in den Sozial- und Kulturwissenschaften. Der Beitrag schließt mit einem Vorschlag für Gütekriterien produktiver Kritik.
Verstrickt in der Rhetorik der Technologie-, Daten- und Medienunternehmen? Zu Problematiken im Umgang mit nicht-wissenschaftlichen Nutzungsdaten
Authors: Fürst Silke
Published: July 2021

Die Kommunikations- und Medienwissenschaft sowie benachbarte Disziplinen fragen zunehmend danach, wie soziales Handeln durch Daten bzw. digitale Spuren gemessen, ausgewertet und repräsentiert wird. Es gibt jedoch nur wenige Analysen dazu, wie die Kommunikations- und Medienforschung selbst in unterschiedlichen Formen solche nicht-wissenschaftlichen Nutzungsdaten verwendet. Dieser Beitrag zeigt, dass Nutzungsdaten von Technologie-, Daten-, Marktforschungs- und Medienunternehmen vielfach mit starker Intransparenz verbunden sind und von der Forschung oft nicht ausreichend hinterfragt und kontextualisiert werden. Über die Aussagekaft der verschiedenen Metriken und Rankings wird zu wenig kritisch diskutiert und auch die mit ihnen verfolgten kommerziellen Interessen und Strategien werden selten in den Blick genommen. Die vorliegende Analyse identifiziert und diskutiert fünf problematische Umgangsweisen mit nicht-wissenschaftlichen Nutzungsdaten: A) Mangelnde Einordnung der Aussagekraft von Nutzungsmetriken und -rankings, B) Mangelnde Einordnung von Rankings als strategische Unternehmensinstrumente, C) Unbegründete Inferenz von Nutzungsdaten auf Makro-Phänomene, D) Unkritische Übernahme von interessengeleiteten Superlativen und Generalisierungen und E) Verwendung von geschätzten Zahlen als gemessene Daten. Die Analyse dieser Problematiken wirft einen kritischen Blick auf die Kommunikations- und Medienforschung, die zum Teil mangelnde Sicherung von wissenschaftlicher Qualität und jüngste Entwicklungen im Wissenschaftssystem. Sie eröffnet zudem neue Fragen und Perspektiven, mit denen die Kommunikations- und Medienforschung einen wichtigen Beitrag leisten kann. Denn gerade in Gesellschaften, in denen Nutzungszahlen und -rankings omnipräsent sind und mächtige Unternehmen den Datenzugang weitgehend kontrollieren, ist ein kritischer Blick auf Nutzungsdaten unverzichtbar.
Critical media practices
Authors: Kannengießer Sigrid , Möller Johanna E.
Published: July 2021

This article develops the theoretical concept of critical media practices. Critical media practices are characterised by two aspects: 1) In critical media practices actors reflect on routines relating to media (as organisations, content, or technologies) and/or on the meta processes mediatisation, digitisation or datafication. 2) On the basis of this reflection actors develop alternative routines in their media practices and shape processes of mediatisation, digitisation or datafication. Critical media practices aim at influencing society and are therefore always political. Conceptualizing the term critical media practices, this article on the one hand contributes to further developing media practices as an approach in communication and media studies, on the other hand, it adds to general debates on critique in this field.
Investigação da relação chuva-deslizamentos no município de Mauá – SP para obtenção de limiares críticos deflagradores de deslizamentos
Authors: Damasceno Aloa Dandara Oliveira , Cardoso Andrea De Oliveira , Paiva Cláudia Francisca Escobar de
Published: July 2021

The Mauá city, Region of Grande ABC Paulista, is among the five municipalities of the São Paulo state with the most critical situation in relation to the number of records of geological accidents, which makes it vulnerable to intense and persistent rainfall. This study investigates the relationship between precipitation events and landslide occurrence in this municipality from the geological-geotechnical characterization of samples representative of the horizons most susceptible to the region's geodynamic processes, precipitation patterns and the frequency of landslides. It was found that rains of different intensities and durations can increase the number of landslides. In addition, the geological and geotechnical characteristics of the region's pedological horizons (residual soil from mica schist and granite) and anthropic interventions contribute to the magnitude of susceptibility to geodynamic and related processes. The curves of landslides obtained, for different criteria of daily and accumulated precipitation before the occurrence, showed that the greater the accumulated value of precipitation, the lower the intensity of daily precipitation necessary to trigger the landslides. The criteria indicated the daily total of 35 mm as the most restrictive, regardless of the value accumulated in days prior to the occurrences, which was validated with the cases of recent landslides occurred in the region, not considered in the calibration of the adjustment equation. In addition, in periods without rain in the previous days, the landslides will tend to occur with rainfall greater than 70 mm on the day of the event, an increase of this value may be observed with the increase in the number of previous dry days.

Published: July 2021

Introduction/purpose: The paper presents a solution for overcoming a possible problem - breach of safety measures when operating the BVP M80A Infantry Combat Vehicle on a training ground during tactical exercises and shooting at night. The crux of the problem is that the officer in charge of a tactical exercise and shooting is not in a position to observe in which direction the gunner-operator aims because no device has been installed on the BVP M-80A to signal this. Methods: After deploying the vehicle in practice and and on the basis of experience during shooting, it was concluded that there is a problem of controlling shooting at night and in reduced visibility conditions. Results: The paper provides a practical solution to prevent situations such as disorientation, impossibility of observing targets, and turning weapons towards the outside the shooting range boundaries, thus violating the security measures of all participants in the exercise including the BVP M80A unit itself. A technical improvement was implemented on the vehicle by installing a signaling device that gives visual information to the officer in charge of shooting in which direction the weapon is turned. Conclusion: The installed signaling device enables the officer who commands the exercise and shooting to be in control in a timely manner, eliminate possible causes of violation of security measures, and successfully implement the planned activity.

Taxonomic papers as published products of the biodiversity inventory: if not the Impact Factor (IF) or Quartiles (Q), then what determines their importance estimated on the basis of the Research Interest Score?
Authors: Dobrynina Viktorija , Baryshnikova Svetlana , Budrys Eduardas , Rimšaitė Jolanta , Bidzilya Oleksiy
Published: July 2021

This study is uniquely based on the Research Interest Score (RGRI) and not on other existing bibliometric criteria for evaluation of published biological inventory products (articles and monographs). RGRI is a ResearchGate.net score that measures scientists’ interest in the publication and is based on its citations, recommendations, and reads. Our data revealed that high RGRI scores of publications were generally not determined by the journal’s Impact Factor (IF) or high quartiles (Q). However, open access to publications undoubtedly creates the strongest preconditions for the rise of RGRI. The importance and popularity of a publications can also be affected by its various other characteristics, for example, international collaboration of authors, ecological issues such as plant-insect interactions, and even the wording of the publication title.
Investigation of mTOR, JAK/STAT, and Hedgehog pathways inhibitor effect on the proliferation of haematological cancer cell lines

Published: July 2021

Constitutively activated JAK/STAT signaling pathway is a common feature of the BCR/ABL-negative classic myeloproliferative neoplasms (MPN). JAK2 small-molecule inhibitors have been proven to be clinically efficacious; however, they are not mutation-specific and competent enough to suppress neoplastic clonal haematopoiesis. There is a need for exploring new therapeutic strategies for MPN. Additional signaling systems, such as PI3K/Akt/mTOR and Hedgehog, are a potential treatment target. The aim of this study was to characterise and compare the effects of specific JAK/STAT, PI3K/Akt/mTOR, and Hedgehog signaling inhibitors in haematological cell cultures. JAK2 p.V617F mutated SET-2 and JAK2 wild-type UT-7 human cell lines were employed in our study. The effect of specific signaling pathway inhibitors was studied as time- and dose-response experiments. Viability was measured by trypan blue exclusion and alamarBlue assays. IC50 values were used to compare the effectiveness of inhibitors in decreasing cell viability. Independent sample t-test was used for statistical comparisons between experimental groups. p < 0.05 was considered significant. Our results indicate that all specific inhibitors progressively reduced the number of viable cells as the concentration and exposure duration increased. Inhibitors impaired the proliferation of JAK2 mutated cells at significantly lower doses compared to wild-type JAK2 cell line. These in vitro data indicate that JAK/STAT and alternative PI3K/Akt/mTOR and Hedgehog inhibitors have a potential anti-proliferative efficacy. Future studies, involving direct screening of PI3K/Akt/ mTOR, JAK/STAT, and Hedgehog signaling molecules activity, at gene and protein level in cell-based MPN model, are required.

Published: July 2021

The inclusion of students with disabilities in the education system results in content or assessment accommodations to suit the students’ special needs and to ensure they have acquired the objectives listed in the curriculum. In this paper, we aim at proposing different ways to accommodate a university English language test to a partially blind student who used text-to-speech tools (TTS) in order to provide them with accurate assessment. To carry out this research, the student has been monitored throughout the course to see which accommodations fit their1 needs best. All in all, we have observed that read-aloud accommodations lead to a better inclusion of the partially sighted student and better performance.
Догма, Литургија и подвиг у ери секуларизма и рационализма
Authors: Вучковић Горан
Published: July 2021

Црква се данас суочава са питањем секуларизма и рационализма. Ситуација је так- ва да је у времену секуларног друштва човјеку допуштено да вјерује, да се занима за мета- физику исто колико је слободан да се бави науком. Осим традиционалистичког приступа вјери, егзистенцијални приступ је остао у сјенци и резервисан само за оне који се баве тео- логијом или пак философијом, тј. за оне чије интересовање надилази уобичајено схватање вјере. Тако долазимо до појма догме. Како савремени човјек разумије догмате Цркве или да ли их уопште разумије? Да ли изван традиционалистичког, етичког, обредног приступа вјери постоји познавање догмата, еклисиологије или свијест о томе како припадамо Цркви? Зашто се о догматима не говори изван катедре? Зашто не постоји еклисиолошки приступ вјери? Да ли су догмати истине запечаћени са „седам печата“ и да ли се догме могу живјети или су оне у сфери имагинарног и апстрактног? Како савременом човјеку пренијети зна- чење догме? То су питања која се налазе у основи овог рада.

Луис близак отачком пре- дању Истока када је у питању проблем теодикеје? Ослањајући се на карактеристична места код Отаца и, пре свега, на Луисово дело Проблем бола (The Problem of Pain), аутор компа- ративно анализира ово питање, истовремено указујући на увек актуелан проблем атеизма који примарно извире из питања праведности Божије а не из питања Његовог постојања.
Човјек као психосоматско биће по учењу апологета
Authors: Лукић Славољуб
Published: July 2021

Посебну пажњу у својим списима апологете придају космолошким и антропо- лошким интересовањима. Човјек је за апологете центар комплетне творевине. Цјелокупан свијет је створен за човјека, у којем он није обична индивидуа или објекат, већ литургијски члан у једној заједници. Он је психосоматско биће, створен од Једног Бога, из два елемента, нематеријалног – душе – и материјалног – тијелa – те се у њему уједињује сва творевина, па је човјек микрокосмос у макрокосмосу. Дакле, човјек је једна личност или ипостас из два позитивна састојка – тијела и душе, којима је заједнички створитељ Један Бог, а који се уједињују у личности човјека и сачињавају једно онтолошко јединство.

Свака земља која постане чланица Савета Европе истовремено је дужна да пот- пише прихватање свих дужности и обавеза којe јој следују по ратификовању Европске конвенције о људским правима. Шта све обухвата обим загарантованих верских права формулисаних у чл. 9. и чл. 11. Европске конвенције о људским правима и колико је доса- дашња судска пракса испоштовала принципе аутономије и аутокефалности Православних Цркава представљаће основу овог рада. Анализа кључних пресуда Европског суда за људска права, које су се на посредан или непосредан начин бавиле односом држава према помес- ним Православним Црквама, може нам дати одговоре на питања у ком смеру се држав- но-црквено право може развијати у будућности и који став Српска Православна Црква у том случају треба да заузме како би се заштитила од оних верских заједница које прете да угрозе интересе наше Цркве.
A Novel Domino Logic with Modified Keeper in 16nm CMOS Technology
Authors: Mehra Anu , Singhal Smita , Tripathi Upendra
Published: July 2021

Domino logic is a clocked CMOS (Complementary Metal-Oxide Semiconductor) logic with fewer transistors than static CMOS logic. A PMOS (P-type Metal-Oxide Semiconductor) transistor, known as “keeper”, is included in the design to improve the noise tolerance performance and to reduce the leakage current. The aspect ratio i.e. W/L of the keeper (W=width and L=length) is kept low for the correct functionality of the domino logic. This paper proposes a domino logic with modified keeper in order to improve the circuit with respect to power and area as compared to various existing techniques of domino logic i.e. clock delayed domino logic (CDD), high speed domino logic (HSD), multi threshold high speed domino logic (MHSD), clock delayed sleep mode domino logic (CDSMD), sleep switch domino logic (SSDD), PMOS only sleep switch domino logic (PSSDD), reduced delay variations domino logic (RDVD) and Foot Driven Stack Transistor Domino Logic (FDSTDL). The proposed as well as existing domino logics, for 8-input as well as 16-input OR gate in 16nm CMOS technology, are simulated for different values of W/L of keeper with W/L ratio ranging from 1 to 6. The power-delay-product(PDP) of proposed design has improved as compared to the existing designs. For 8-input OR gate and W/L=6, PDP had improved to maximum of 99.99% for CDD and minimum of 38.09% for SSDD.

Second Generation Current Controlled Conveyor (CCCII) based tunable Dual Output Sinusoidal Oscillator (MSO) is proposed. It consists of three CCCIIs, a resistor and two grounded capacitors. By tuning external DC bias current, the oscillator frequency and commencement of its oscillations are controlled electronically. The proposed circuit is verified using PSPICE simulator and also on laboratory breadboard using commercially available integrated circuits Current Feedback Operational Amplifier (AD844AN) and Operational Transconductance Amplifier (LM13600) at a supply rail voltage of ±6 V. Further its nonlinearities, sensitivities, performance characteristics are also verified. Comparison of the proposed topology with the ongoing methods are also undertaken. PSPICE simulation results are verified with a low supply voltage of ±1 V, temperature analysis, analysis by using Montecarlo method and finally Total Harmonic Distortion (THD) is also demonstrated.
Contribution to Time and Frequency Analysis of Irregular Sleep Snoring
Authors: Alimohad Abdennour , Rezki Mohamed
Published: July 2021

The purpose of this paper is to give a summary analysis of human snoring and its episodes. In particular, we consider an acute snoring. In order to extract some frequency information of snoring signal, we apply the Fast Fourier Transform (FFT), Short Time Fourier Transform (STFT) algorithms, Discrete Wavelet Technique, and Power Spectral Density (PSD). Once irregular snoring characterized, we use a Voice Activity Detection (VAD) for snoring episode detection. Furthermore, we give comparative study of three types of thresholds that can control the VAD approach, a fixed threshold, a soft threshold, and a Gaussian threshold. Next, we use a Perceptual Evaluation of Speech Quality (PESQ) method to evaluate the efficiency of the VAD. We find that VAD based on Gaussian threshold is better.
Revisiting Analytical Models of N-Type Symmetric Double-Gate MOSFETs Shaded Conditions
Authors: Uddin Ahmed Rekib , Saha Prabir
Published: July 2021

Nowadays, the endlessly increasing demand for faster and complex integrated circuits (IC) has been fuelled by the scaling of metal-oxide-semiconductor field-effect-transistors (MOSFET) to smaller dimensions. The continued scaling of MOSFETs approaches its physical limits due to short-channel effects (SCE). Double-gate (DG) MOSFET is one of the promising alternatives as it offers better immunity towards SCEs and can be scaled to the shortest channel length. In future, ICs can be designed using DG-CMOS technology for which mathematical models depicting the electrical characteristics of the DG MOSFETs are foremost needed. In this paper, a review on n-type symmetric DG MOSFETs models has been presented based on the analyses of electrostatic potential distribution, threshold voltage, and drain-current models. Mathematical derivations of the device models are described elaborately, and numerical simulations are also carried out to validate the replicability of models.
Sensitivity Analysis of the UTBSOI Transistor based Two-Stage Operational Amplifiers
Authors: Uddin Ahmed Rekib , Akshay Vijaykumar Eklare , Saha Prabir
Published: July 2021

In the nanoscale domain, the MOSFETs are prone to various physical effects due to their shorter channel region known as short-channel effects (SCE). The researchers have proposed an advanced structure of MOSFET known as the ultrathinbody silicon-on-insulator (UTBSOI) to overcome the limitations of SCEs. The UTBSOI is a type of double-gate (DG) MOSFET having superior controllability of gates over the shorter channel region. Nowadays, the UTBSOI MOSFETs can be adopted in the circuit simulators through the use of a device model named BSIM-IMG. The BSIM-IMG has made it possible for the circuit designers to simulate any UTBSOI based analog blocks like operational amplifiers (opamp). The performance parameters of an opamp are very much sensitive to any perturbation in size (W/L) of the constituent MOSFETs, that may cause a drastic change in the output. In this paper, the sensitivity analysis procedure has been proposed for the CMOS and UTBSOI based two-stage opamps as the function of perturbation in W/L. In addition to this, an algorithm has also been presented to do the same. From the simulation results, it is observed that the sensitivity of the UTBSOI based opamp (UTBSOI-opamp) is larger than that of CMOS based opamp (CMOS-opamp).

Background: We sought to evaluate clinicians’ compliance with national guidelines for tetanus vaccination prophylaxis in patients with high-risk feet.

Methods: We retrospectively evaluated 114 consecutive patients between June 1, 2011, and March 31, 2019, who presented to the emergency department with a foot infection resulting from a puncture injury. Eighty-three patients had diabetes mellitus and 31 patients did not have diabetes mellitus. Electronic medical records were used to collect a broad range of study data on patient demographics, medical history, tetanus immunization history and tetanus status on presentation to the emergency department, peripheral arterial disease, sensory neuropathy, laboratory values, and clinical/surgical outcomes.

Results: Of the 114 patients who presented to the emergency department with a puncture wound, 53 (46.5%) did not have up-to-date tetanus immunization. Of those patients, 79.2% received a tetanus-containing vaccine booster, 3.8% received intramuscular tetanus immunoglobulin, 3.8% received both a tetanus-containing vaccine booster and tetanus immunoglobulins, and 20.8% received no form of tetanus prophylaxis. Comparing data between patients with and without diabetes mellitus, there were no statistically significant differences in tetanus prophylaxis.

Conclusions: Guidelines for tetanus prophylaxis among high-risk podiatric medical patients in this study center are not followed in all patients. Patients with diabetes mellitus are at high risk for exposure to tetanus; therefore, we recommend that physicians take a detailed tetanus immunization history and vaccinate patients if the tetanus history is unclear.
Light alters the impacts of nitrogen and foliar pathogens on the performance of early successional tree seedlings
Authors: Brown Alexander , Heckman Robert W.
Published: July 2021

Light limitation is a major driver of succession and an important determinant of the performance of shade-intolerant tree seedlings. Shade intolerance may result from a resource allocation strategy characterized by rapid growth and high metabolic costs, which may make shade-intolerant species particularly sensitive to nutrient limitation and pathogen pressure. In this study, we evaluated the degree to which nitrogen availability and fungal pathogen pressure interact to influence plant performance across different light environments. To test this, we manipulated nitrogen availability (high, low) and access by foliar fungal pathogens (sprayed with fungicide, unsprayed) to seedlings of the shade-intolerant tree,Liquidambar styraciflua, growing at low and high light availability, from forest understory to adjacent old field. Foliar fungal damage varied with light and nitrogen availability; in low light, increasing nitrogen availability tripled foliar damage, suggesting that increased nutrient availability in low light makes plants more susceptible to disease. Despite higher foliar damage under low light, spraying fungicide to exclude pathogens promoted 14% greater plant height only under high light conditions. Thus, although nitrogen availability and pathogen pressure each influenced aspects of plant performance, these effects were context dependent and overwhelmed by light limitation. This suggests that failure of shade-intolerant species to invade closed-canopy forest can be explained by light limitation alone.
