High drain-current-density and high breakdown-field Al0.36Ga0.64N-channel heterojunction field-effect transistors with a dual AlN/AlGaInN barrier layer
Authors: Inoue Akiyoshi , Tanaka Sakura , Egawa Takashi , Miyoshi Makoto
Published: January 2022

In this study, we fabricated and characterized heterojunction field-effect transistors (HFETs) based on an Al0.36Ga0.64N-channel heterostructure with a dual AlN/AlGaInN barrier layer. The device fabrication was accomplished by adopting a regrown n++-GaN layer for ohmic contacts. The fabricated HFETs with a gate length of 2 μm and a gate-to-drain distance of 6 μm exhibited an on-state drain current density as high as approximately 270 mA mm−1 and an off-state breakdown voltage of approximately 1 kV, which corresponds to an off-state critical electric field of 166 V μm−1. This breakdown field, as a comparison in devices without field-plate electrodes, reaches approximately four-fold higher than that for conventional GaN-channel HFETs and was considered quite reasonable as an Al0.36Ga0.64N-channel transistor. It was also confirmed that the devices adopting the dual AlN/AlGaInN barrier layer showed approximately one order of magnitude smaller gate leakage currents than those for devices without the top AlN barrier layer.
Proton transport over nanoparticle surface in insulating nanoparticle film-based humidity sensor
Authors: Kano Shinya , Mekaru Harutaka
Published: January 2022

We study proton transport on the surface of insulating nanoparticles for humidity sensors. We use this approach to reveal proton transfer mechanisms in humidity-sensitive materials. Hydrophilic and hydrophobic ligand-terminated silica nanoparticle films are adopted for evaluating the temperature dependence of the ion conductivity. According to the activation energy of the conductivity, we explain that Grotthuss (H+ transfer) and vehicular (H3O+ transfer) mechanisms are mainly dominant on hydrophilic (−OH terminated) and hydrophobic (acrylate terminated) surfaces of the nanoparticles, respectively. This investigation gives us a clue to understanding the proton transfer mechanism in solution-processed flexible humidity-sensitive nanomaterial films.

Authors: Yadav Dev Kumar , Baig M Q
Published: January 2022

Gallbladder cancer (GBC) is the 6th most common gastrointestinal malignancy and most common hepatobiliary malignancy representing 85-90% worldwide with an annual incident of 2/1,00,000 and marked 1 geographical and ethnic variability and known for late diagnosis and poor outcome. High rates of gallbladder carcinoma are seen in different parts of the world like South America (Chilli, Bolivia, and 2 Ecuador) as well as in some parts of India (specically in north IndiaUP, Bihar, Delhi, West Bengal, Assam, and Madhya Pradesh, mostly in Gangetic belt), Pakistan, Japan, and Korea. In north India, gallbladder cancer is 10 times more common in comparison to south India. R 3 Kanthan et al . (2015) divides the risk factor for GBC into four broad groups: i)Patient demography, ii) GB abnormalities, iii)patient exposure to a specic chemical, genetic and molecular factors, iv) Infection. This study says that not only gallbladder stones but also infection by some microbial agents like salmonella and helicobacter also having contributory risk factors
EGFR EXPRESSION IN PRIMARY EPITHELIAL URINARY BLADDER TUMORS AND ITS CORRELATION WITH CLINICOPATHOLOGICAL PARAMETERS
Authors: Sharma Deepika , Sharma Sudarshan Kumar , Raina Pamposh , Gulati Anchana
Published: January 2022

Introduction: EGFR is over expressed in many epithelial tumors including urothelial carcinomas. Over expression of
EGFR is considered as a poor prognostic marker in various studies. Thus, the present study was done to evaluate the
EGFR expression in primary urothelial carcinomas and its correlation with clinicopathological parameters.
Methods: This was a cross-sectional, observational study carried out between June 1, 2019 to May 31, 2020 in the Department of Pathology and
Urology, Indira Gandhi Medical College, Shimla. One hundred and ninety seven patients with primary epithelial urinary bladder cancer were
included. Patients with inammatory and metastatic lesions of urinary bladder and post chemoradiotherapy were excluded. The correlation
between EGFR expression and the various factors like age (<60 years or ≥60 years), sex (male/female), size of tumor (< 3cm or ≥ 3cm), number
of tumors (solitary/multiple) and grade (high/low) were evaluated using EpiInfoV.7 software version and chi-square test.
Results: The age of patients ranged from 36 to 89 years. Male preponderance was observed. Most common clinical presentation was painless
hematuria. EGFR positivity was observed in majority, 190 cases, irrespective of histological type and grade of tumor. No statistical signicant
correlation was found between EGFR expression and age of patient, size of tumor, number of tumor and histological grades of urothelial tumors.
Conclusion: Majority of urothelial carcinomas over expressed EGFR irrespective of their histological grade. So, targeted EGFR therapy in
urothelial carcinomas can emerge as a novel therapy improving overall survival and prognosis of the patients with urothelial carcinomas.
Outperforming Sequential Full-Word Long Addition with Parallelization and Vectorization
Authors: Chusov Andrey
Published: January 2022

The paper presents algorithms for parallel and vectorized full-word addition of big unsigned integers with carry propagation. Because of the propagation, software parallelization and vectorization of non-polynomial addition of big integers have long been considered impractical due to data dependencies between digits of the operands. The presented algorithms are based upon parallel and vectorized detection of carry origins within elements of vector operands, masking bits which correspond to those elements and subsequent scalar addition of the resulting integers. The acquired bits can consequently be taken into account to adjust the sum using the Kogge-Stone method.
Essentially, the paper formalizes and experimentally verifies parallel and vectorized implementation of carry-lookahead adders applied at arbitrary granularity of data. This approach is noticeably beneficial for manycore, CUDA and vectorized implementation using AVX-512 with masked instructions.

Authors: Solomay T. V. , Semenenko T. A. , Tutelyan A. V. , Bobrova M. V.
Published: January 2022

Introduction. The Epstein–Barr virus (EBV) is one of the most common pathogens — it infects 90% of the world’s population. However, specific characteristics of the EBV infection epidemic process remain unidentified. The previous studies focusing on assessment of incidence rates for infectious mononucleosis (IM) tend to ignore the serological status of the population.The aim of the study was to identify epidemiological characteristics and assess the prevalence of serological markers for EBV infection for further epidemic control measures development.Materials and methods. In Moscow, the thorough analysis was performed using the data on IM incidence (Form 2 "Data on Infectious and Parasitic Diseases") and test results for 138,232 people checked for presence of VCA IgG, EBNA IgG, VCA IgM, EA IgG, and EBV DNA in their blood and saliva in 2011–2020.Results. The periodic pattern of IM incidence was discovered, demonstrating the repetitive peaks every 9 to 11 years and a strong direct correlative relationship with detection rates for active EBV infection markers. The intra-annual dynamics of IM incidence is characterized by a seasonal upswing during cold seasons of the year, reaching its peaks in October, November, or February and associated with a marked decrease in the VCA IgG and EBNA IgG seroprevalence. Children within the 1 to 17-year age range are groups at risk for acquiring primary infection, demonstrating significantly lower detection rates for chronic EBV infection (VCA IgG and EBNA IgG) markers and higher rates for VCA IgM and EBV DNA markers in blood compared to adults. The contribution of adult population to the epidemic process is formed through reactivation of chronic infection, which is observed primarily among women.Conclusion. The identified characteristics are essential for comprehensive understanding of the EBV infection epidemic process and can be used for developing preventive and anti-epidemic measures.

Introduction. A significant increase in the incidence of pertussis in the world, including among adolescents and adults, the prevalence of mild forms of the disease and asymptomatic carrier of bacteria B. pertussis, and the resulting need for mass revaccination of different age groups determine the demand for new vaccines against B. pertussis. In N.F. Gamaleya Federal Research Center for Epidemiology and Microbiology, a live intranasal pertussis vaccine for the prevention of pertussis (GamLPV) has been developed. The GamLPV vaccine underwent preclinical studies that proved its safety and effectiveness in experiments on small laboratory animals and nonhuman monkeys. Safety of vaccine is shown in clinical studies on healthy volunteers.The aim of the study is to assess the immunogenicity of different doses of the drug GamLPV when first used in healthy volunteers.Materials and methods. The study was conducted as randomized placebo-controlled, blind trial with consistent volunteer inclusion and dose escalation. Study ID in clinicaltrials.gov database: NCT03137927 (A Phase I Clinical Study of a GamLPV, a Live Intranasal Bordetella Pertussis Vaccine). The following parameters of humoral and cellular immune responses were assessed in dynamics: levels of specific IgM, IgG and IgA antibodies in blood serum of volunteers and the number of cytokines interleukin-17, tumor necrosis factor-α, interferon-γ produced after specific induction in vitro of blood mononuclears of vaccinated volunteers. Dynamics of attenuated bacteria persistence in nasopharynx of vaccinated volunteers was evaluated.Results. Intranasal vaccination of volunteers with the drug Gam LPV resulted in the formation of a specific humoral (IgG and IgA) and cellular immune response. The dose-dependent nature of immunoglobulin and cytokine production was shown. Attenuated bacteria persisted for a long time in the nose/oropharynx of vaccinated volunteers.Discussion. Good tolerability of all tested doses of the drug justifies the choice for further investigation of a vaccine dose equal to 4 × 109 CFU. At the next stage, the safety and immunogenicity of two-time vaccination of volunteers will be studied.

The activities of the organizational boundary spanners during the Covid19 pandemic: the case of a profit organization
Authors: Tino Concetta
Published: January 2022

In the first period of emergency from Covid19, only workplace organizations with essential production activities were able to continue to carry out their work. This required them the implementation of organizational strategies useful to contrast the risk of the pandemic and to protect production performance. The qualitative study conducted in a Lombard company, through semi-structured interviews, aimed at figures with different levels of responsibility, wanted to investigate: (i) which boundary spanning activities were used to manage the emergency? (ii) what factors allowed the effectiveness of the result in terms of contrasting the pandemic and guaranteeing the productivity (iii), what were the perceived effects on the company? Findings highlight the importance of the activities of organizational boundary spanners in emergency management and of those factors that, by supporting the socio-emotional dimension, have determined the organization’s productive advantage.

 

Le attività dei boundary spanners organizzativi durante la pandemia da Covid19: il caso di un’organizzazione profit.

 

Nel primo periodo della diffusione dell’emergenza sanitaria da Covid19, solo le organizzazioni lavorative con attività produttive essenziali hanno potuto continuare a svolgere il loro lavoro. Questo ha richiesto loro la messa in atto di strategie organizzative utili a contrastare il rischio della diffusione della pandemia e a salvaguardare la performance produttiva. Lo studio qualitativo condotto, in un’organizzazione profit lombarda, tramite interviste semistrutturate, rivolte a figure con diversi livelli di responsabilità ha voluto investigare: (i) quali attività di boundary spanning sono state utilizzate per gestire l’emergenza? (ii) quali fattori hanno consentito l’efficacia di risultato in termini di contrasto alla pandemia e di garanzia produttività (iii), quali sono state le ricadute percepite sull’organizzazione? I risultati ottenuti evidenziano l’importanza delle attività dei boundary spanners organizzativi nella gestione dell’emergenza e di quei fattori che sostenendo la dimensione socio-emozionale ne hanno determinano il vantaggio produttivo dell’organizzazione.
Rethinking school inclusion during and after the pandemic: some reflections
Authors: Guerini Ines , Montanari Mirca , Ruzzante Giorgia , Travaglini Alessia
Published: January 2022

This contribution, of a theoretical nature, focuses on the complex educational situation that emerged immediately after the lockdown period and extended to this day. The authors, in fact, reflect on how the legislative restrictions, issued in favor of containing the spread of Covid-19, have significantly decreased the chances of building/maintaining significant relational bonds. This has consequently had a negative impact on the development of inclusive processes as well as on the learning level of many students, especially for the most vulnerable ones. For this reason, the authors try to question what prospects and what possibilities will open in the post-pandemic period, keeping in mind the unavoidable need to re-think the school, both from an organizational and an educational-didactic point of view.

 

Ripensare l’inclusione scolastica durante e dopo la pandemia: alcuni spunti di riflessione.

 

Il presente contributo, di carattere teorico, si focalizza sulla complessa situazione educativa delineatasi subito dopo il periodo del lockdown e prorogatasi finora. Le autrici, difatti, riflettono su come le restrizioni normative, emanate in favore della riduzione del contagio da Covid-19, abbiano sensibilmente diminuito le possibilità di costruire/mantenere legami relazionali significativi. Questo ha, conseguentemente, avuto un impatto negativo sullo sviluppo dei processi inclusivi nonché sul livello apprenditivo di numerosi alunni, soprattutto di quelli più vulnerabili. In ragione di ciò, le autrici provano a interrogarsi su quali prospettive e su quali possibilità si aprano nel periodo post-pandemia, avendo bene in mente l’ineludibile esigenza di ri-pensare la scuola, tanto dal punto di vista organizzativo quanto da quello educativo-didattico.
Work and disability during the Covid-19 outbreak: from the current scenario to possible future perspectives
Authors: Lecce Amelia , Di Gennaro Diana Carmela , Sibilio Maurizio
Published: January 2022

Ensuring work for people with disabilities today represents an important goal for democratic states and a continuous challenge for policy makers who should always aim to improve targeted placement services. Unfortunately, this goal, although regulated by specific laws, does not always find fertile ground in its applicability, sometimes increasing marginalization and discrimination. In this regard, the Covid-19 outbreak has brought out new forms of exclusion and new needs, increasing, in some cases, inequalities within workplaces. Therefore, starting from the scenario outlined by the pandemic, the paper aims to propose a reflection on the importance of work for people with disabilities, as a tool of self-empowerment that promotes inclusive processes, analyzing the legislative framework regarding access to work for vulnerable people and outlining possible future perspectives to promote inclusion within work places.

 

Lavoro e disabilità ai tempi del Covid-19: dallo scenario attuale a possibili prospettive future.

 

Garantire una occupazione lavorativa alle persone con disabilità rappresenta oggi una conquista per gli Stati democratici e una continua sfida per i policy makers che dovrebbero sempre puntare a migliorare i servizi di collocamento mirato. Purtroppo, tale conquista, sebbene normata da leggi ad hoc, non sempre trova terreno fertile nella sua applicabilità, alimentando, talvolta, i fenomeni di emarginazione e i meccanismi di discriminazione. A tal proposito, l’emergenza sanitaria da Covid-19 ha fatto emergere nuove forme di esclusione e nuovi bisogni incrementando, in alcuni casi, le disparità in ambiente lavorativo. Dunque, partendo dallo scenario delineato dalla situazione pandemica, il contributo intende proporre una riflessione circa l’importanza del lavoro per le persone con disabilità, in quanto strumento di self-empowerment che favorisce i processi inclusivi, analizzando il quadro normativo in materia di diritto e di accesso al lavoro per i soggetti più fragili e tratteggiando possibili prospettive future per promuovere percorsi lavorativi inclusivi.
Finally at school: the return to classes of vulnerable pupils. Results of the FocuScuola Inclusion research 20.20
Authors: Zanfroni Elena , Maggiolini Silvia , D'Alonzo Luigi
Published: January 2022

The research FocuScuola 20.20 – promoted by the Centre for Studies and Research on Disability and Marginality of Università Cattolica del Sacro Cuore – aims at specifically understanding the state of the art of the inclusive processes at the return to school after the first lockdown period. This research is in line with the aims of national and international surveys that have analysed the challenges to which the school system has been called in this period of health and social emergency. The collected data show a picture that seems to confirm the critics linked to an ideological and reductive scenario. This view is although characterized by some positive elements in terms of reception and attention to students with greater vulnerability, but it is substantially distant from the realisation of educational pathways that assume educational differentiation as an authentic perspective and concrete working method.

 

Quando tutto è ricominciato: il ritorno a scuola degli alunni più fragili. Esiti della ricerca FocuScuola Inclusione 20.20.

 

La ricerca FocuScuola 20.20 – promossa dal Centro Studi e Ricerche sulla Disabilità e la Marginalità dell’Università Cattolica del Sacro Cuore – ha inteso comprendere in modo specifico lo stato dell’arte dei processi inclusivi al rientro a scuola dopo il primo periodo di lockdown. Lo studio è in linea con le finalità di indagini nazionali e internazionali che hanno analizzato le sfide a cui il sistema scolastico è stato chiamato in questo periodo di emergenza sanitaria e sociale. I dati raccolti evidenziano un quadro che, seppur caratterizzato da alcuni elementi positivi sul piano dell’accoglienza e dell’attenzione verso gli alunni con maggiore vulnerabilità, sembra confermare le criticità legate ad una visione per molti aspetti ideologica e riduttiva, sostanzialmente lontana dalla realizzazione di percorsi educativi che assumano la differenziazione didattica come autentica prospettiva e concreta modalità di lavoro.

Pratiche mediali, social media e influencers nella formazione e nell’espressione identitaria dei bambini: una ricerca esplorativa
Authors: Pacetti Elena , Soriani Alessandro
Published: January 2022

With the spread of social media, we witnessed the multiplication of web’s figures such as influencers and content creators. The pupils in the last years of primary schools (9-11 years old), engaged in a complex task of defining their own identity, are strongly exposed to entertainment contents conveyed by social networks and online video platforms. The present exploratory study, which involved 173 students from a primary school in Emilia-Romagna Region (Italy), aims to investigate the role of social media and influencers in the formation and expression of the identities of children, highlighting a universe little known and only superficially explored by teachers and adults with educational roles. The contribution has the twofold objective of: investigating children’s practices related to social networks (in particular those based on video content such as YouTube, Twitch, TikTok, Instagram and Snapchat) to offer an overview of the situation in an age group increasingly targeted by these social networks; making a reflection on how much the figures of content creators and influencers play a role in the identity formation of children in 4th and 5th year of primary school. The results lead to new research questions and educational path to make teachers and parents more aware of this issue.

The research presented in this article investigates the artistic practices of Mauro Lanza, Andrea Valle and Simone Pappalardo, with particular attention to the concrete use and the theoretical definition of their new electromechanical and electroacoustics instruments. The paper considers the works Le Nubi non scoppiano per il peso (2011) by Mauro Lanza, the cycle Selva Petrosa (2019-2020) by Andrea Valle, the cycle Systema Naturae (2013-2017) by Andrea Valle and Mauro Lanza, and the performative practice by Simone Pappalardo. Starting from the definition of instrumental apparatus, the discussion presents the organological problems related to the new electromechanical and electroacoustic lutherie, and examines the definitions of electromechanical and electroacoustic instrument. The works of the three composers are analyzed from the point of view of the instrumental equipment, by investigating the algorithmic control techniques of the musical materials that have been used for organizing the instrumental component, and the different signals for controlling the computational component.
The Development of the !trumpet
Authors: Collins Nicolas
Published: January 2022

The !trumpet is software synthesis system controlled from, and playing back through, a trumpet.  It is not an electronically extended trumpet: the player produces no acoustic sounds by blowing through the mouthpiece. Instead, breath pressure and valve movement on the brass instrument are read by an embedded Arduino microcontroller  and sent to a laptop, where the data is mapped onto various parameters in synthesis software; the resulting electronic sound is returned to the trumpet, where it plays through a loudspeaker inside the bell, and is further processed acoustically by valve position (changes in the length of tubing filter the speaker output), movement of a plunger mute (wah-wah style filtering), and orientation of the instrument in space (panning).
Competitiveness framework to support regional-level decision-making in the wine industry: a systematic literature review
Authors: Mota Jorge , Costa Rui , António Moreira  , Serrão Silvana , Costa Carlos
Published: January 2022

This study aims to identify the main performance indicators and group them in dimensions within a regional competitiveness framework to support decision-making in the wine industry. For this research, a systematic literature review (SLR) was conducted in the Scopus database. There is a limited number of studies identifying indicators with impact on the performance of wine regions, and even fewer studies including indicators in an integrated approach to measure the different dimensions of wine regions’ performance. From a set of 85 papers, only 9 studies related to performance indicators with a specific focus on the regional level were considered. We document that under a convention framework, economic and territorial indicators cover 84.90% of all SLR indicators analysed, and under a regional competitiveness framework, infrastructure and innovation and intellectual capital indicators fill 81.25% of all the indicators. As this group of indicators is limited to a set of sub-dimensions, we found that several groups of indicators are misrepresented, such as the ones related to human and socio-cultural capital areas, which play a crucial role in the regional competitiveness of the wine industry. This paper contributes to the literature identifying indicators according to convention and regional competitiveness frameworks in three dimensions – economic, environmental and territorial dimensions and five main areas – productive capital, human capital, socio-cultural capital, infrastructure and intellectual capital. These indicators are to be used at regional-level to support decision-making in the wine industry. For regional entities, it discloses the most pertinent indicators which need improvement to craft regional strategies. This framework is of added value for policymakers to customize their support programmes so that specific producers can enhance their competitive strategies. It could also be deployed in teaching programmes as a tool to address the importance of aligning different types of indicators to achieve better performance in the wine industry.

Las dificultades ambientales generadas por la erosión marina que amenaza a la comunidad de Bahía La Rada en las costas de Córdoba, Colombia y en particular por su cercanía con su institución educativa rural del mismo nombre, permitieron analizar la relación del aprendizaje sobre la erosión marina como contenido científico y la formación de líderes ambientales en estudiantes de educación secundaria. Se utilizó una metodología cualitativa con alcance interpretativo, mediante un análisis de contenido cualitativo (ACC), análisis documental, observación no participante y entrevistas semiestructuradas. La población participante fue de tipo no probabilística e intencional constituida por 15 estudiantes, 4 niñas y 8 niños, de edades entre 12 y 16 años. Los resultados permitieron identificar cuatro criterios para la formación de Líderes Ambientales Escolares (LAE): educar para lo ambiental, formar para construir ambiente, liderar para transformar el contexto y compartir lo transformado, implementados a través de la propuesta de un módulo tutor ambiental que vincula sinérgicamente los contenidos ambientales escolares enseñados y las problemáticas socioambientales del contexto de los estudiantes. Finalmente, se recomienda promover una dinámica colectiva de conciencia ambiental y empoderamiento de los estudiantes como una necesidad educativa para la generación de compromisos y acciones en favor de la transformación del aprendizaje de las ciencias naturales aplicadas a soluciones ambientales contextuales.
Efecto bactericida del ácido acético presente en el vinagre, una alternativa a desinfectantes sintéticos o químicos. Revisión sistemática.

Tradicionalmente, en ambientes como laboratorios, el hogar o en lugares dedicados a la manipulación de alimentos, se suelen emplear desinfectantes de tipo sintético, que por el alto contenido de agentes químicos como el cloro, llegan a producir efectos perjudiciales para la salud. En la actualidad se han evaluado alternativas para producir y utilizar sustancias amigables con el medio ambiente, que sean lo menos nocivas posible, en este sentido se ha venido promoviendo el uso de desinfectantes ecológicos. En el caso de las cocinas, por ejemplo, la sobreexposición al uso de un desinfectante químico puede traer complicaciones al personal que labore allí y además el alimento pueda alterarse por efectos de la contaminación cruzada. Un ejemplo de alternativa de desinfección, que vale la pena revisar es el Vinagre, sus características químicas relacionadas con la presencia de ácido acético en concentración alta, puede desencadenar procesos de degradación más rápidos, que a su vez inciden en minimizar el riesgo tóxico asociado a sustancias químicas y sintéticas. 

Centrado en lo anterior, el semillero PGAE adscrito al programa de Ciencias Básicas de la Universidad Colegio Mayor de Cundinamarca orientó una revisión sistemática centrada en las propiedades químicas del Vinagre y de su constituyente fundamental (el ácido acético). Este trabajo fue presentado en la edición regional del encuentro de semilleros RedColsi (2021) en el marco de la investigación formativa y a continuación se relacionan los resultados más relevantes que sugieren la necesidad de realizar investigaciones centradas en el tema en cuestión, como una alternativa que pueda replicarse y usarse de manera generalizada en el marco de la química verde.

Authors: Herrera López Mauricio , Romera Eva , Ortega Ruiz Rosario
Published: January 2022

Las relaciones interpersonales entre adolescentes son relevantes en el aprendizaje y la convivencia escolar. Se analizó las dimensiones individuales y contextuales que influyen en las relaciones interpersonales entre adolescentes. Participaron 1084 adolescentes escolarizados (52.8% mujeres) del sur de Colombia, con edades entre 11 y 19 años (M=14.9; SD=1.89). Se analizaron las propiedades psicométricas de las escalas utilizadas. Un modelo de ecuaciones estructurales informó las relaciones e influencias de la empatía, prosocialidad, metas sociales, autoeficacia social y ajuste normativo sobre la calidad de sus relaciones interpersonales (ajuste social). Se encontraron óptimas propiedades psicométricas para las escalas y adecuados ajustes del modelo explicativo-predictivo; éste indicó que la empatía, prosocialidad y autoeficacia social con los compañeros predicen la calidad de las relaciones interpersonales. Resalta la influencia negativa de la autoeficacia social con profesores hacia la calidad de las relaciones, y del ajuste normativo sobre el desempeño social con compañeros. Se discuten orientaciones para el desarrollo de la prosocialidad y empatía.

يهدف البحث الى التعرف على مدى معرفة الملاك الوظيفي في مكتبة الجامعة التكنولوجية بمفهوم الإدارة الالكترونية وقدرته على التعامل مع تكنولوجيا المعلومات في تقديم الخدمات للمستفيدين و معرفة اتجاهات العاملين حسب المستويات الادارية نحو تطبيق الادارة الالكترونية والوقوف على العوامل التي تحد من تلك الاتجاهات ، و اعتمد البحث على منهج دراسة الحالة لتحديد مدى تطبيق الإدارة الالكترونية في مكتبة الجامعة وتحديد المعوقات التي تحول دون تطبيقها. و توصل البحث الى جملة من  الاستنتاجات منها:

أن ادارة المكتبة لا تمتلك المتطلبات المادية والتقنية كافة لتطبيق الادارة الالكترونية وذلك لعدم تلائم متطلباتها مع الواقع الفعلي للمكتبة .

أن الملاك الوظيفي يرى ان تطبيق الادارة الالكترونية لا يساعد على تحقيق السرعة في ايصال التعليمات لهم .

اما أهم المقترحات  التي تم جاء بها البحث فكانت كالاتي : -

ضرورة توفير كافة المتطلبات المادية والتقنية اللازمة لتطبيق الادارة الالكترونية لما لها من تأثير ايجابي على أداء المكتبة والخدمات التي تقدمها للمستفيدين منها .

زيادة وعي الملاك الوظيفي بأهمية تطبيق الادارة الالكترونية من خلال اشراكه في ورش عمل وحلقات نقاشية ودورات تدريبية توضح اهميتها في تحسين الأداء وزيادة الكفاءة .
الحجاج البلاغيّ في الشعر السياسيّ الشاعر أحمد مطر أنموذجاً
Authors: وهيب العنبكي أ.م.د. ساهرة عدنان
Published: January 2022

يسعى الجدل التداولي إلى فهم الأدلة الحجاجية ، وتحليلها ونقدها ، وفرز الأدلة الصائبة أو الضعيفة ، وتصنيف الحوارات ورصد الآلية الجدلية والتوقف عند الحوار النقدي ، إذ تعد البلاغة آلية من آليات الحجاج لاعتمادها على الاستمالة والتأثير والاقناع ، بالصورة البيانية ، والأساليب الجمالية وممارستها الإقناع الفكري ، والشعور النفسي لتقبل القضية الحجاجية في موضوع الخطاب ، إذ يتكون البناء الحجاجي من مفاهيم يختص بها الأديب، والشاعر ، والفيلسوف ، وحجته في ذاته التعبيرية التواصلية مع الآخر ، فيعرف مفاهيمه بحسب اطروحة النص المنتج ، وتحليل تلك العلاقات بين المفاهيم كعلاقات التضاد والتطبيق والتضمين .... الخ . فيتحول النص من تواصلي إلى مفهوم حجاجي ، والهدف منه هو الإقناع الذي يتوصل إليه من خلال الحوار المشترك مع الجماعة ، أو الآخر بالتفاوض أو التحقيق ، أو المداولة ، أو البحث عن المعلومة ، أو المحادثة النقدية وفهم الأدوات المستعملة في بناء الحوار بالتركيز على السياق .

      وحظي شعر أحمد مطر في العصر الحديث بعناية كبيرة من الباحثين والدارسين ، نظرا لإبعاده الوظائفية ، وقدرته على استمالة الجمهور ( القراء ) بالحجاج والبرهان ، والاقناع ، وحتى الاستدلال .

Published: January 2022

In recent time, various kinds of young brown (low-rank) coals are utilized increasingly not only as fuels, but also as valuable materials in advanced environmental applications. It should be noted in this context that significant deposits of the young brown coals can be found both in the Czech Republic as well as in Slovakia. For their effective applications e.g. in wastewater treatment or in soil remediation, the properties of the coals should be studied in more details and numerous physico-chemical characteristics should be measured. As a part of a common Czech-Slovak project, a series of various kinds of coals was collected, including North-Bohemian oxihumolites, lignite from South Moravia and several lignites from Slovakia (Baňa Zahorie). Basic properties were measured, such as acid-base titration curves, contents of main functional groups and sorption capability towards heavy metal cations (Cu2+, Zn2+, Co2+) and some organic pollutants. The contents of humic substances – main active constituents of the young coals – were also determined. Selected environmental applications of the brown coals will be mentioned further, e.g. for the removal of metal cations from waters or in phytoremediation of contaminated soils.

Authors: Pisarčíková Gabriela , Závodská Lucia , Lesný Juraj
Published: January 2022

85Sr as radioindicator has been applied to strontium separation selectivity study using cisdicyclohexano-18-crown-6 (DCH18C6) as extraction agent and picric acid as counter ion with the aim to contribute to the development of a rapid method of strontium extraction. The same radioindicator has been used for strontium fractionation study in chosen soils by application of Tessier- and BCR sequential extraction procedures. Experimental results have shown, that the mentioned extraction system is applicable for IDA determination of Sr2+ in ∼1000-fold abundance of Ca2+, ∼1000-fold abundance and Mg2+, ∼10-fold abundance of K+ and ∼0.2-fold abundance of Ba2+. For the soil samples - chernozems developed on loess - from the near vicinity of NPP Jaslovské Bohunice the exchangeable strontium fraction reached as much as 50 – 60 %.
