Effect of curing temperature and clinker content on hydration and strength development of calcined clay blends
Authors: Emmanuel Arun C. , Bishnoi Shashank
Published: July 2022

The effect of temperature (10°C, 27°C and 50°C) on the hydration kinetics, phase assemblages and strength development of calcined clay blends (CCBs) was investigated at two replacement levels. The temperature sensitivity of the CCBs significantly increased when clinker was replaced with calcined clay, even at a 30% replacement level. The compressive strength development of the CCBs was higher than that of ordinary Portland cement at a lower temperature, perhaps due to the formation of low-density products such as stratlingite rather than enhanced clinker hydration. The reduced compressive strength development of the CCBs cured at 50°C could be due to multiple reasons (e.g. lower clinker hydration, reduced pozzolanic reaction, reduced stability of carboaluminates and ettringite). However, merely a 24-h lag in temperature exposure reversed this temperature effect, mainly due to the enhanced stability of carboaluminate and ettringite phases. The reduction in hydration was mainly in the belite phase and could be due to large changes in calcium alumina silicate hydrate having a high alumina substitution. It is hypothesised that the adverse effect of high-temperature exposure on CCBs is due to the formation of a physical barrier of highly polymerised calcium silicate hydrate on the surface of unhydrated clinker. The improved performance due to the delay in high-temperature exposure could be due to the enhanced stability of ettringite and carboaluminate phases.
The construction of the Cross Bay Link bridge in Hong Kong
Authors: Wang Yanhua , Liu Hai Long , Mak Stephen , Hu Chengrui
Published: July 2022

The Cross Bay link (CBL) bridge is a 1 km sea crossing that forms the centrepiece of the new east–west express highway link in Hong Kong. This £250 million project features an iconic 200 m span butterfly double-arch bridge and a series of concrete box girder spans supported on specially sculpted V-piers and large piled foundations. This paper describes the innovative construction methods adopted for building the bridge safely and efficiently in an extremely challenging marine environment, a process that relied on the extensive use of design for manufacture and assembly solutions, with most of the bridge elements above the sea level being prefabricated or precast off site. This includes the construction of the 10 000 t steel arch bridge, which was fully prefabricated near Shanghai, then transported to Hong Kong by a semi-submersible barge, and eventually erected onto the piers using the float-over method. In addition, most of the concrete decks, piers and the pile cap shells were precast off site and then lifted into position on site. This project holds a number of engineering records in Hong Kong, including the longest arch bridge, the first-time adoption of S690QL high-strength steel for major bridge elements and the largest scale implementation of the float-over erection method.

Objective. Interictal epileptiform discharges on EEG are integral to diagnosing epilepsy. However, EEGs are interpreted by readers with and without specialty training, and there is no accepted method to assess skill in interpretation. We aimed to develop a test to quantify IED recognition skills.

Methods. A total of 13,262 candidate IEDs were selected from EEGs and scored by eight fellowship‐trained reviewers to establish a gold standard. An online test was developed to assess how well readers with different training levels could distinguish candidate waveforms. Sensitivity, false positive rate and calibration were calculated for each reader. A simple mathematical model was developed to estimate each reader's skill and threshold in identifying an IED, and to develop receiver operating characteristics curves for each reader. We investigated the number of IEDs needed to measure skill level with acceptable precision.

Results. Twenty‐nine raters completed the test; nine experts, seven experienced non‐experts and thirteen novices. Median calibration errors for experts, experienced non‐experts and novices were ‐0.056, 0.012, 0.046; median sensitivities were 0.800, 0.811, 0.715; and median false positive rates were 0.177, 0.272, 0.396, respectively. The number of test questions needed to measure those scores was 549. Our analysis identiﬁed that novices had a higher noise level (uncertainty) compared to experienced non‐experts and experts. Using calculated noise and threshold levels, receiver operating curves were created, showing increasing median area under the curve from novices (0.735), to experienced non‐experts (0.852) and experts (0.891).

Significance. Expert and non‐expert readers can be distinguished based on ability to identify IEDs. This type of assessment could also be used to identify and correct differences in thresholds in identifying IEDs.

Published: July 2022

Objective. We aimed to determine a possible association between motor and mental development in infants of women with epilepsy and antenatal exposure to antiseizure medication (ASM).

Methods. Developmental paediatricians who were blinded to antenatal ASM exposure evaluated motor and mental development of infants (>12 months) using the Developmental Assessment Scale for Indian Infants (an Indian adaptation of the Bayley Scale of Infant Development). Motor (MODQ) and mental development quotients (MEDQ) were computed as ratios of respective developmental age to the chronological age of the child. We employed linear mixed models to study the relationship between antenatal exposure to ASM and the development quotients after adjustment for malformation status and age of the baby, maternal education and seizure type.

Results. We studied 1,357 infants with mean age of 15.3±4.0 months (71.2% of all eligible infants). Infants were classified as having monotherapy or polytherapy, or unexposed in 840, 407 and 110 participants, respectively. The MEDQ of the polytherapy (92.9±14.9) and monotherapy (96.9±13.9) groups was lower than that of unexposed infants (99.8 12.5). Similarly, the MODQ of polytherapy (91.1±19.3) and monotherapy (96.6±17.5) groups was lower than that of unexposed infants (97.6 16.6). The differences in adjusted mean MEDQ were ‐7.4 (‐11.4 to ‐4.3, p=0.001), ‐9.6 (‐11.3 to ‐6.0, p=0.001) and ‐6.4 (‐9.2 to ‐3.7, p=0.001) for valproate monotherapy, polytherapy with valproate and polytherapy without valproate, respectively. The adjusted mean MODQ also showed a similar trend. Those exposed to levetiracetam (n=62) had higher or similar adjusted MODQ (110.4±14.3; p=0.001) and MEDQ (104.3±9.1; p=0.09), compared to unexposed infants. A dose‐dependent decrease in developmental indicators was observed for valproate and phenobarbitone.

Significance. Antenatal exposure to ASM, especially valproate and phenobarbitone, adversely affects motor and mental development of exposed infants. Early developmental screening of high‐risk infants is desirable.
Considerations in the design of electrical substations, including the effect of potential gradient on surrounding metallic structures
Authors: Chiliquinga Wilo , Robles Pablo
Published: July 2022

For designing and studying an electrical substation grounding system [GS], a simple remote substation is considered according to the safety procedures indicated in the IEEE 80 Standard. Buried metallic materials or nearby metallic structures permanently endanger human life when electrical faults occur. Scenarios related to the design of electrical substations that consider the transfer of electrical potentials that can occur between the GS and buried metallic materials in their vicinity are presented, the behavior of potential transfer is evaluated, values of transferred voltages are calculated, and the main variables that influence the transferred voltage levels are identified. The simulations are performed with the CYMGRD software specific for GS calculations. Its analysis generates real results in the potential transfer that must be considered by the GS design engineer, which enables to avoid designing isolated substations without taking into account existing elements that may affect the substation surroundings.

The rapid development and spread of new information and telecommunication technologies is acquiring the character of a global information revolution today, which has an increasing im-pact on politics, economics, management, finance, science, culture and other spheres of society within national borders and in the world as a whole. This is used not only by conscientious users of communication networks, but also by malefactors pursuing various illegal goals – personal enrichment, discrediting citizens and state bodies, spreading illegal information, ideas of terrorism and extremism. There is also a rapid growth of new types of crimes related to the use of information systems. All this requires the creation of new computer forensics tools (forensics), which is able to process a large amount of information and help in the identification, dis-closure and investigation of crimes. The article analyzes the directions of modern development of automation of search and analysis of criminally significant information. Various types of electronic traces for different types of crimes are considered. New forms of using a number of elements of artificial intelligence and the use of mathematical apparatus within the automation of expert systems to obtain the necessary evidence in relevant criminal cases are proposed. A recommendation system is proposed, which, with the help of multifactor analysis, will allow to form a "portrait" of a person based on the data contained on the user's electronic media.
"Somos –cómo podríamos evitarlo– funcionarios de la humanidad". El testamento filosófico de Edmund Husserl
Authors: Vargas Bejarano Julio César
Published: July 2022

En 1936, en su última obra, Crisis, Husserl afirma que la filosofía ejerce una función orientadora con respecto a la cultura. El propósito de esta investigación es mostrar que la caracterización del filósofo como "funcionario de la humanidad" está en estrecha conexión con la fenomenología de la experiencia: ciencia de la ‘doxa’, ciencia del mundo de la vida. En la década del treinta, Husserl desarrolla una fenomenología de la facticidad, fenomenología de la subjetividad trascendental, cuyo carácter es monádico, pero cuyo ser tan solo adviene real mediante relaciones intersubjetivas. La ciencia del mundo de la vida permite establecer que en la raíz de la crisis de la cultura occidental se encuentran el 'dualismo psico-físico', el 'objetivismo' y el 'naturalismo'. Para superarlos se requiere revalorizar la doxa, y mostrar cómo en ella tiene lugar la constitución, el a priori, del mundo de la vida.

Self-Regulated Learning Method Through Smartphone Assistance in Promoting Speaking Ability
Authors: Menggo Sebastianus , Darong Hieronimus Canggung , Semana Ignas Loy
Published: July 2022

Self-regulated learning is a method of the student-centered learning paradigm. This method encourages students to be actively involved in the learning process, organize themselves, recognize their capabilities, and take the initiative to decide the appropriate way to achieve the learning achievement. The use of self-regulated learning with smartphones' assistance has had a double effect on students' language proficiency. However, the self-regulated learning method with smartphone assistance in the speaking class has not been supported by current empirical studies. The evidence indicates that self-regulated learning with smartphones' assistance affects students' English skills, such as acuity in micro-and macro-linguistics analysis, improved digital literacy, enthusiasm for learning, and self-potential development autonomy. This study aimed to analyze the impact of using the self-regulated learning method with smartphones in the speaking class. This review is a quantitative study with a pre-test and post-test design that was executed between October 2020 until January 2021. 110 students were chosen as samples in this study. An English-speaking rubric has been used to obtain data; that data was then analyzed by a software application that is SPSS 24.0, which was proceeded by qualitative description. The findings demonstrate that using a self-regulated learning method with smartphone assistance has positively impacted student speaking ability. This increased effect is demonstrated by the adjusted mean score on the post-test = 82.32. English instructors are encouraged to apply this method by considering students' characteristics, cognitive capacities, learning styles, learner autonomy, and the steps of how to apply this method in the instruction process.

Published: July 2022

Background: In Mathematics Education, the theoretical reference of Advanced Mathematical Thinking has contributed to some research. However, others opt for a different but somehow related theoretical reference. Identifying the similarities and differences between those references can elucidate the researcher’s motivations when adopting one or another reference. Objective: to synthesise three studies involving Mathematical Creativity, Advancing Mathematical Activity and Advanced Mathematical Knowledge, respectively, and to illustrate possible contributions of those theoretical references in the analysis of a written production. Design: the research is qualitative and theoretical and speculative so that theoretical relationships were carried out and used later in the analysis of the written production. Setting and Participants: the research involves a participant with a degree in mathematics with whom the researchers had a virtual interaction to present the questions. Data collection and analysis: the procedures performed in the resolution of questions prepared based on the OBMEP question bank are analysed and, with the support of this example of analysis, possible contributions of each reference in the analysis of a written production are discussed. Results: none of the references covers all the thinking mobilised in the activity, but each one favours the focus on specific aspects that were verified in the written production of the research participant, in line with the similarities and divergences emphasised in the theoretical appreciation of each reference. Conclusions: the knowledge of different theoretical frameworks provides the teacher with foundations to exercise their teaching practice and the researcher with options for an adequate choice for their research.

Published: July 2022

The study of a criminal personality is a crucial task not only in the scope of criminal psychology of today but also for others: forensic sciences, jurisprudence, sociology, etc. Understanding the criminal personality's characteristics is important for diagnosis, designing of psycho-corrective measures, and development of preventive measures. For psychological research, it is interesting to study the deep aspects of personality, it can help to identify the main causes of what is amenable to external observation: one’s behaviour, emotional reactions. Thus, the purpose of this work is to study the personality structure of people who have committed serious crimes. The theory of G. Ammon serves as the methodological basis. The sample: 30 men convicted of violent crimes (art. 105, art. 111 of the Criminal Code of the Russian Federation: murder and intentional infliction of grievous bodily harm, respectively) and 30 men who did not commit offences. The obtained results indicate that the perpetrators of violent crimes have both external (p=0.000) and internal (p=0.000) person-ality boundaries violated; the research revealed violations in the functioning of the Self-system (reflection of the integrity of the personality, its mental unity).

The article presents the research results of the values of persons who have committed terrorist crimes (N=124), in comparison with law-abiding citizens (N=80). In accordance with the concept of M. Rokeach, terminal and instrumental values are considered separately. The author’s version the sentence completion test was used with an original scheme of qualitative and quantitative data processing. Among the most significant differences in terminal values is the high importance of religious values for terrorist criminals. Significant differences in the frequency of mentioning among the instrumental values were observed in the quality of “fairness”. It was mostly used by criminals, and law-abiding persons mentioned “decency” more often.

The article discusses the results of the empirical research into the psychological features of individuals prone to cyber victimization. As a theoretical basis, this paper uses the analysis of the findings of the studies conducted by the Russian as well as foreign researchers, that indicate presence of the specific traits among victims of cyber crime. The focus group that took part in the research includes 78 adult users of the VK social network. The respondents who became victims of cyber scams more than twice over the past three years were identi-fied as the individuals prone to cyber victimization. The following techniques were used for the empirical data collection: Multifactorial personality questionnaire (16 PF) by R.B. Cattell, “Level of subjective control” test by V.F. Bazhin, E.A. Golynkina and A.M. Atkind and State-Trait anxiety inventory by C. Spielberger (adapted by Y. Khanin). The results of the conducted research show that one's tendency towards cyber victimization can be explained by the presence of certain specific emotional and interpersonal traits. The findings of this study could be used as major targets for designing preventive programs against crimes in cyber space.

La educación en México ha tenido una serie de fracasos y mejoras a lo largo de los años, cuyas causas pueden estar en los nuevos mo­delos educativos que escenifican las familias, irracionalidades de planes curriculares, la deficiente/eficiente administración de la secre­taria de educación, al comportamiento variante del alumnado o al profesionalismo del docente. Si bien cada aspecto tiene un impacto destacable en la formación de los estudiantes, el docente es quien escenifica todo lo que está detrás del esquema organizacional en el tema educativo, es quien termina ejecutando las decisiones tomadas. La intención de este estudio es generar una explicación sobre el comportamiento del alumnado a partir del papel que juega el docente dentro del aula visto desde las teorías de liderazgo docente, y a su vez, como este es influenciado por las condiciones laborales con las que debe hacer frente. El punto de referencia es el docente de edu­cación secundaria pública en el noroeste de México. Recordamos que la preparación en este nivel educativo es un paso decisivo para la continuidad de los estudios de todo joven, constituyendo el último tramo de educación obligatoria, cursar los siguientes niveles es una decisión más personal y de oportunidad. Se describe el contexto situacional que le espera por vivir a todo docente, la problematización de sus condiciones actuales y posteriormente de la elección de teorías pertinentes para la generación de un modelo que sirva para el estudio y análisis de su labor, así como una propuesta de abordaje metodológico para su comprobación.

DevelNet: Earthquake Detection on Develocorder Films with Deep Learning: Application to the Rangely Earthquake Control Experiment
Authors: Wang Kaiwen , Ellsworth William , Beroza Gregory C. , Zhu Weiqiang , Rubinstein Justin L.
Published: July 2022

There exists over a century of instrumental seismic data; however, most seismograms recorded before the 1980s are only available in analog form. Although analog seismograms are of great value, they are underutilized due to the difficulties of making quantitative measurements on the original media and in converting them to digital time series. In this study, we present an alternative workflow, based on deep learning, to reconstruct an earthquake catalog from images of analog data without conversion to vector time series. We trained a convolutional neural network—DevelNet, using synthetic analog data to detect earthquakes on scanned multichannel Develocorder film images. We then developed an image-based processing workflow to measure arrival times, locate, and determine the magnitudes of earthquakes in the data. We demonstrate the performance of this approach on two years of continuous Develocorder film recordings from the Rangely earthquake control experiment in the mid-1970s. Our approach detects twice the number of events reported in the original catalog (Raleigh et al., 1976). This demonstrates that DevelNet efficiently detects earthquakes from Develocorder film scans, performs consistently over time, and is robust to changes in network geometry. Our locations generally agree with the original study, although the automatically measured arrival times are less precise than manual reading, leading to increased location scatter. Our automatic workflow of Develocorder films rivals the performance of skilled analysts in earthquake detection, but with minimal human intervention. This image-based processing offers a new approach for effectively and efficiently extracting earthquake information from analog seismic data.

Published: July 2022

Muchas instituciones y expertos en educación han desarrollado programas basados en la enseñanza integrada en STEM (Science, Technology, Engineering, Mathematics) debido a los beneficios asociados a la misma. Nuestro objetivo ha sido analizar la efectividad didáctica de talleres STEM (grupo experimental) frente a la metodología académico-expositiva (grupo control). Participaron más de 200 estudiantes de 5º y 6º de primaria. Se diseñaron varios cuestionarios para valorar variables cognitivas y afectivas. Los datos confirman la efectividad de los talleres STEM como estrategia metodológica en el aula de primaria, al observarse que el grupo experimental mantiene los aprendizajes adquiridos a largo plazo y el grupo control vuelve a su nivel de conocimientos inicial. A nivel afectivo, se observó que el grupo experimental manifestó mayoritariamente emociones como diversión o satisfacción y los estudiantes del grupo control manifestaron emociones como aburrimiento y enfado.

¿Pornografía al alcance de un clic? Una revisión de la literatura reciente sobre adolescentes españoles
Authors: Alonso Ruido Patricia , Sande Muñiz María , Regueiro Bibiana
Published: July 2022

Las tecnologías de la información y la comunicación (TICs) proporcionan un acceso constante e inmediato a una amplia gama de información y recursos. Los/as adolescentes, habitualmente considerados/as nativos/as digitales, utilizan los medios tecnológicos y los espacios virtuales para explorar su dimensión sexuada accediendo a contenidos pornográficos. La revisión bibliográfica que se presenta en este trabajo tiene un doble objetivo: evaluar el consumo de pornografía entre los adolescentes españoles y analizar las variables asociadas desde una perspectiva de género El estudio consiste en una revisión sistemática de trabajos sobre adolescentes españoles publicados entre 2016 y 2020. Los resultados muestran que acceden a contenidos pornográficos por primera vez alrededor de los 12 años, y que el consumo de pornografía se consolida durante la adolescencia, especialmente en el caso de los varones, que son los principales consumidores. También muestran que la pornografía es una fuente de información para muchos adolescentes que no reciben suficiente educación sexual ni en casa ni en la escuela. El consumo de pornografía durante la adolescencia está asociado a una serie de consecuencias, como el sexismo, la violencia y el consumo de sustancias, y puede conducir a una visión distorsionada de la sexualidad. La situación que revelan estos resultados pone de manifiesto la necesidad de apoyar la educación sexual en la familia y en la escuela para dotar a los jóvenes de las herramientas necesarias para disfrutar de su sexualidad de forma plena y responsable.

Published: July 2022

El objetivo de este estudio era analizar las propiedades psicométricas de la versión española del Children’s Negative Cognitive Errors Questionnaire (CNCEQ) en una muestra de población joven. El CNCEQ es uno de los procedimientos de autoinforme más utilizados para medir cuatro tipos de distorsión cognitiva (pensamiento catastrófico, sobregeneralización, personalización y abstracción selectiva) en tres áreas de contenido (social, académica y deportiva). A pesar de ello, no existen estudios que analicen las propiedades del instrumento entre los jóvenes. El estudio utilizó una amplia muestra (N = 2040; entre 12 y 22 años; 50,7% hombres y 47,3% mujeres) de diferentes centros educativos. La validez de constructo se evaluó mediante un análisis factorial exploratorio, y la consistencia interna mediante el coeficiente alfa de Cronbach. También se realizaron contrastes de medias para evaluar la validez discriminante y se llevó a cabo un análisis de correlación y regresión para explorar la validez de criterio. Los resultados indican que el CNCEQ permite evaluar las distorsiones cognitivas autodegradantes entre los jóvenes con suficientes garantías psicométricas. Su uso por parte de los profesores les permitirá adaptar sus actividades para tener en cuenta la presencia de distorsiones cognitivas entre sus estudiantes.

O objectivo deste estudo é apresentar as principais conclusões do processo de tradução e da adaptação da Escala de Empregabilidade Autopercebida (SPES) à população universitária portuguesa, com base numa amostra de 526 estudantes. Os resultados das análises realizadas sobre os itens confirmam a qualidade psicométrica da SPES. Relativamente à validade de constructo (CFA), os índices de qualidade do ajustamento para ao modelo em um (Empregabilidade Percebida), em dois (Empregabilidade Interna e Empregabilidade Externa) e em quatro fatores (Mercado de Trabalho, A Minha Universidade, Campo de Estudo, Competências Pessoais) foram bastante satisfatórios. Contudo, no modelo de um factor, foi necessário eliminar quatro itens; no modelo de dois factores, foram eliminados três itens na empregabilidade interna e dois na empregabilidade externa, e no modelo de quatro factores, foram eliminados quatro itens. Quanto à validade convergente da escala, os resultados foram os esperados, tendo-se verificado que o SPES estava significativamente associado à adaptabilidade da carreira, à auto-eficácia na transição da escola para o trabalho, e às intenções e comportamentos de procura de emprego. Em síntese, os bons níveis de fiabilidade e validade obtidos parecem apoiar a utilização da versão portuguesa do SPES na avaliação da empregabilidade percebida entre os estudantes universitários portugueses.

BACKGROUND: The incidence of diabetes is growing, and diabetics have increased risk of atherosclerosis and diffuse coronary artery disease (CAD). Our aim was to assess the revascularization treatment of diabetics with CAD in Iceland from 2010-2020, changes in management and long-term survival of patients. METHODS: All patients in Iceland with diabetes and CAD on cardiac catheterization 2010-2020 were included in this retrospective, population-based study. We analyzed data from the SCAAR/SWEDEHEART database: patients‘ background information, findings of cardiac catheterization, planned treatment and results. The Kaplan-Meier method was used to estimate long-term survival and Cox-regression-analysis to adjust for predictor variables. RESULTS: Of 1905 cases (1485 patients), 1230 (65%) underwent PCI, 274 (14%) CABG and 401 (21%) had medical therapy only. The age distribution differed: The PCI group had the widest age bracket, the CABG group the narrowest, and the medical therapy group had the highest mean age. Most patients with STEMI or cardiogenic shock underwent PCI, while most patients with concomitant heart-valve disease underwent CABG. The proportion of patients undergoing CABG increased with more diffuse CAD. 41% of patients with left main- and three-vessel disease underwent CABG while only 2% of those with single-vessel disease. From 2010-2020 the proportion of patients that underwent PCI increased from 49% to 72%. There was no difference in survival between the PCI and CABG groups (p=1.00). CONCLUSION: Three quarters of patients with diabetes and obstructive CAD are now treated with PCI. The PCI and CABG groups had overall equal survival but the groups had different characteristics.

Background and purpose: Dryocosmus kuriphilus is considered as one of the major pests of sweet chestnut and the effective method of controlling its populations and damage is the biological control with its introduced parasitoid Torymus sinensis. T. sinensis is a univoltine, host specific parasitoid, phenologically synchronized and morphologically adapted to D. kuriphilus. It has a good dispersal ability, it builds up populations quickly and it effectively controls the pest already few years after the release. In this paper we describe the first results of the introduction and release of T. sinensis for controlling the populations of invasive D. kuriphilus in sweet chestnut forests and orchards in Croatia, Hungary and Slovenia.  Materials and methods: Withered D. kuriphilus galls with T. sinensis larvae were collected in Torino vicinities, Italy, in March 2014 and March 2015. After emergence, males and females were put together, kept at 14°C and fed with liquid honey until the release. To confirm the establishment of the population of T. sinensis on release site from 2014 in Croatia morphological and DNA identification were used. Fresh galls from the release site of Pazin, Croatia were collected in spring 2015 and parasitism rates of T. sinensis were calculated. Results and conclusions: In total 10,590 females and 5,295 males of T. sinensis were released in sweet chestnut forests in Croatia, Hungary and Slovenia in 2014 and 2015. The minimum release number of T. sinensis was 100 females/50 males and the maximum was 1,200 females per site. Subsequent releases with a larger number of females (1,200 and 800 in two years) resulted in a rapid establishment of the population of T. sinensis and parasitism rates of 76% only one year after the first release was done. The establishment of the population of T. sinensis was confirmed with molecular analyses and morphological identification. Obtained haplotype sequences of T. sinensis have shown similarities with Torymus beneficus. Prior to the release of T. sinensis, all advantages and disadvantages of the introduction of this alien biocontrol species into natural stands in Croatia, Hungary and Slovenia have been considered.

Background and purpose: Staphylococcus sp. are pathogenic bacteria widely investigated for its high incidence in clinical environments and its ability to form strong biofilms. The biofilm-related infections can resist several antimicrobial agents; therefore, the therapy of these infections may face difficulties. The aim of this study is to identify staphylococcal bacteria isolated from dental clinics, evaluate the effect of some disinfectants on removing the preformed biofilms and to demonstrate the adhesion of cells on the surfaces of some materials used for manufacturing the dental material using Scanning Electron Microscope (SEM). Material and Methods: Out of 70 different swabs, 12 Staphylococcal isolates were recovered. All isolates were subjected to 13 antimicrobial agents to test their sensitivity. The biofilm established isolates, as well as the effect of some disinfectant as removal agents of the preformed biofilm were estimated using microtiter plate (MtP) test. SEM was used for demonstrating biofilm formation by the tested isolates on stainless steel and rubber surfaces. Results: Of 12 Staphylococcus isolates, 33.3, 16.6 and 50% were shown strong, moderate and weak biofilm producers, respectively. Adhesions of the preformed biofilm were found to be reduced in the presence of betadine and sodium bicarbonate. Captured photographs by SEM confirmed the capability of biofilm formation by S. aureus H3 and S. hominis M0401 on stainless steel and rubber surfaces. Conclusion: the effective preventive strategies for infection control are essential to prevent staphylococcal infections in the dental clinics. This study reveals effective antibiofilm agents as betadine and sodium bicarbonate.
