De Twitter a la prensa digital: el caso Braian Gallo
Authors: Gomez Wagner Celeste
Published: March 2021

En los últimos años ha aumentado la cantidad y el espacio asignado en las coberturas a la representación mediática del delito. Quiénes aparecen como protagonistas de los sucesos que se relatan en las noticias y cómo se los caracteriza son aspectos centrales en la construcción que los medios hacen de este tema. El presente trabajo aborda el caso de Braian Gallo, un joven que participó como autoridad de mesa en las elecciones presidenciales argentinas de 2019 y fue sujeto de mensajes discriminatorios que comenzaron en Twitter y se replicaron en la prensa digital. La atención estuvo puesta en su vestimenta y aspecto, así como en su afiliación política. El artículo repone cuáles fueron las características particulares que abonaron a la relevancia del caso en la cobertura mediática digital; y reflexiona sobre dos figuras desplegadas en el tratamiento noticioso: el “pibe chorro” y el “pobre bueno”. Concluye que la tensión entre informar y reproducir continúa vigente en el modelo actual de la prensa digital y que podría, incluso, ser alentada por alguna de sus exigencias.

El análisis abarca el periodo comprendido entre enero de 1976 y agosto de 1977.

En cuanto a los aspectos metodológicos, este trabajo se inscribe en un análisis interpretativo, a partir de categorías que provienen de la Sociosemiótica y de la Translingüística.
Los unos y los otros: vidas comunes en tiempos digitales
Authors: Carpentieri Yanina Andrea , Grinberg Silvia , Armella Julieta
Published: March 2021

En este artículo proponemos discutir la potencia de los entornos digitales de articular lo común e intervenir en la vida pública a partir de resultados de investigación en escuelas secundarias emplazadas en contextos de extrema pobreza urbana de la Región Metropolitana de Buenos Aires que recupera a la producción audiovisual como forma de indagación e intervención en las instituciones. Para ello se retoman reflexiones de los jóvenes, las maneras en que aspiran a devenir unos en un mundo en el que se saben siendo otros. Aquello que esperan que ocurra cuando la circulación de sus relatos emerge tensionando los marcos de interpretación de quien mira y posibilita, desde la escuela, la producción de un común donde caben muchos otros que no quedan aplazados, donde la palabra emerge e interpela.
“Derribar las fronteras mentales"
Authors: Almirón Sabá María de los Ángeles
Published: March 2021

En este trabajo se explora la interpelación ideológica en discursos contemporáneos en cuya materialidad aparece la idea de frontera en torno de la presencia de un sujeto empresario-de-sí-mismo. Se analiza así cómo es fabricado el sujeto en discursos psicologistas del yo en tanto “creador de realidades deseadas” y “administrador de vínculos deseables”, interpelándoselo como individuo dotado de la potencia y del deber de transformar su vida gestionando sus relaciones con los otros, y atribuyéndose sus determinaciones al plano inmaterial de lo mental en dicha interpelación.
The changing map of subnational governance in the Republic of Ireland
Authors: Breathnach Proinnsias , O’Mahony Eoin , van Egeraat Chris
Published: March 2021

The evolution of the territorial structure of Ireland’s system of local government during the period of colonial rule by England is outlined. The independence period saw little change in this structure until the abolition of municipal-level government in 2014, reflecting the very marginal role of devolved administration in Ireland’s political system. The creation and functioning of regional-level administrative systems, mainly related to the management of EU Structural Fund expenditure, are reviewed. Regional assemblies, established in 2015, have the role of preparing regional strategies under the 2018 National Planning Framework. Ongoing problems arising from a mismatch between subnational governance systems and underlying socio-spatial structures are discussed.
Cartesian space robot manipulator clamping movement in ROS simulation and experiment
Authors: Mu Longtao , Zhou Yunfei , Zhao Tiebiao
Published: March 2021

This paper studies the robot arm sorting position control based on robot operation system (ROS), which works depending on the characteristics of the robot arm sorting operation using the top method, to automate the sorting operation and improve the work efficiency of workpiece sorting. Through the ROS MoveIt! module, the sorting pose and movement path of the robotic arm are planned, the inverse kinematics of the sorting robotic arm is solved, and the movement pose characteristics of the sorting robotic arm are analysed. The robot arm model was created using Solidworks software, and the URDF model file of the robot arm was exported through the sw2urdf plugin conversion tool, and the parameters were configured. Based on ROS for 6-degree-of-freedom (DOF) robot motion simulation, random extended tree (RRT) algorithm from open motion planning library (OMPL) is selected. The robot motion planning analysis and sorting manipulator drive UR5 manipulator. The results show that the sorting pose and motion trajectory of the robot arm are determined by controlling the sorting pose of the sorting robot arm, and the maximum radius value of the tool centre point (TCP) rotation of the robot arm and the position of the workpiece are obtained. This method can improve the success rate of industrial sorting robots in grabbing objects. This analysis is of great significance to the research of robots’ autonomous object grabbing.
Evaluation of stress distribution on all-on-four concept and conventional implant designs: 3D finite element analysis
Authors: Kaya İlhan , Tuğcu Funda
Published: March 2021

Background/Aim: The objective of this study was to evaluate the stress distribution on implants and supporting bone tissue in All-on-Four and conventional designs in edentulous mandible by using 3D finite element analysis. Material and Methods: The different five models were designed according to All-on-Four concept and conventional implant placement designs. While the first two models were involved in All-on-Four concept with two long implants, the remaining models were designed by conventional approaches with three implants in different location and length. After the modelling procedures, a load of masticatory force was applied and the stresses were evaluated. Results: It has been observed that principal stresses in both cortical and spongious bone tissue were concentrated in models of All-on-Four design. Less principal stress levels were found in models of conventional design. Similarly, von Mises stress values on implant surfaces were found to be higher in All-on-Four concept. Conclusions: In severely resorbed mandible, the use of conventional implant placement is recommended. Although All-on-Four design seems to be a reasonable alternative for edentulous mandible, evidence-based results of this approach should be supported by long-term follow-up studies.

Published: March 2021

Background/Aim: The aim of this study was to evaluate the distance between the mental foramen and the upper and lower edges of the mandible in the Turkish population according to different gender and age groups. Material and Methods: A total of 1756 samples of 878 patients who presented at the Dentomaxillofacial Radiology Department of the Dentistry Faculty of Dicle University were included in the study for evaluation of the distance between the mental foramen and the upper and lower edges of the mandible. The cone beam computed tomography (CBCT) images were taken using an I-CAT Vision device (Imaging Science International, Hatfield, USA). Multiple variance analysis was used in the statistical analyses of the data. Results: A statistically significant difference was identified between the genders in respect of the distance of the external edge of the mental foramen from the upper edge of the mandible (p=0,000). In the evaluations of the different age groups, no statistically significant difference was determined. A statistically significant difference was determined between the gender and age groups in respect of the distance of the mental foramen from the lower edge of the mandible (p=0,000). Conclusions: The distance of the mental foramen from the upper and lower edges of the mandible can show variations according to age and gender. Therefore, the use of CBCT as a 3-dimensional imaging method with a low radiation dose is recommended.
Multi-Method Luminescence Dating of Old Fluvial Sediments from Northern Tian Shan, China
Authors: Li Kechang , Qin Jintang , Chen Jie , Shen Jun , Li Sheng-Hua
Published: March 2021

At the eastern tip of Anjihai anticline on the northern piedmont of Tian Shan (northwest China), deformed fluvial deposits have recorded active folding since the Pleistocene, but the absence of accurate ages makes it difficult to evaluate the anticline's shortening rate. Geological studies ascribed the fluvial strata to the early Pleistocene, which poses potential challenges for luminescence dating. In this study, multi-methods luminescence dating was applied to a fluvial sand sample taken from the sandy bed of the deformed basal strata. Single grain post-Infrared Infrared Stimulated Luminescence (pIRIR) and multiple-aliquot-regenerative (MAR) dose along with multiple-elevated-temperature pIRIR (MET-pIRIR) procedures were applied to determine the paleodose of the sample. The methodological uncertainties, such as thermal transfer and initial sensitivity change, were treated by increasing the test dose and performing dose recovery test. With consideration of the potential partial bleaching and anomalous fading, various statistical metrics were applied to the De values determined by using the single grain pIRIR225, single grain pIRIR290 and MAR-MET-pIRIR290 signals. The minimum age model (MAM) De values are 11% – 17% lower than the central age model (CAM) De values in general, and the MAM De values determined by the single grain pIRIR procedures are underestimated by more than 40% when compared with those determined by MAR-MET-pIRIR290 procedure. The MAM MAR-MET-pIRIR290 De of 811 ± 44 Gy results in a burial age of 284 ka for the basal deformed fluvial strata, which is much younger than the proposed early Pleistocene age.

Human alveolar echinococcosis (AE) is a silently-progressing disorder that has become a threat in many countries. Since 2000, when the first case was recorded, the number of human AE patients in Slovakia is on continuous raise. The article presents a rare case of alveolar echinococcosis with infiltration in the adrenal gland and discusses the problems associated with differential diagnosis of the disease. In 2016, abdominal ultrasound performed due abdominal pain complaint showed the presence of cystic lesions in the right liver lobe of 54-year old female patient. During surgery, another lesion in the right adrenal gland was found, and neoplastic processes or echinococcosis were considered in the differential diagnosis. Due to unclear correlation between radiology, serology and histopathology results and endemic situation in Slovakia, molecular examination was recommended. Subsequently E. multilocularis was confirmed as etiological agent of infection. Alveolar echinococcosis is considered as a rare disease, with very few patients referred to clinicians or hospitals that sometimes have almost none existing experience with the diagnosis and treatment of the disease. Therefore, the establishment of networks or reference centres specialized on management of the disease would be suitable way to provide the patients with the best care and improve the disease diagnosis, treatment and prognosis.

Published: March 2021

Aphelenchoides pseudogoodeyi has recently been reported in association with seeds of forage grasses and rice in Brazil and senescent strawberry plants, in the United States. This nematode is likely a mycophagous species; however, so far, its pathogenicity potential to plants is unclear. This study aimed to verify the pathogenicity of A. pseudogoodeyi to two species of ornamental plants. The experiments were conducted by inoculating A. pseudogoodeyi onto Bird’s-Nest Fern (Asplenium nidus) and Oriental Lily (Lilium speciosum) leaves, using two inoculation methods (with and without injury). After 40 days of inoculation (DAI) in Bird’s-Nest Fern and 5, 10, 20 and 40 DAI in Oriental Lily, the pathogenicity and the host efficiency were evaluated by symptoms observation and by severity, final nematode population and reproductive factor (RF), respectively. Additionally, a histopathological study was performed by inoculating A. pseudogoodeyi onto Bird’s-Nest Fern for observing anatomical alterations. A. pseudogoodeyi was able to cause local necrotic lesions on both Bird’s-Nest Fern and Oriental Lily leaves. However, the presence of injury was essential to enable A. pseudogoodeyi to penetrate and cause those symptoms in both plant species. Also, the total population of A. pseudogoodeyi decreased drastically over time and RF was <1, which characterized these species as poor-host or resistant plants. A. pseudogoodeyi penetrated into the foliar tissue and induced a total destruction of the mesophyll and collapse of the cells, with the formation of large intercellular spaces. It is concluded that A. pseudogoodeyi is an opportunistic pathogen as injury was required to induce symptoms in Bird’s-Nest Fern and Oriental Lily.
Computer Analysis of Dynamic Reliability of Some Concrete Beam Structure Exhibiting Random Damping
Authors: Bredow R. , Kamiński M.
Published: March 2021

An efficiency of the generalized tenth order stochastic perturbation technique in determination of the basic probabilistic characteristics of up to the fourth order of dynamic response of Euler-Bernoulli beams with Gaussian uncertain damping is verified in this work. This is done on civil engineering application of a two-bay reinforced concrete beam using the Stochastic Finite Element Method implementation and its contrast with traditional Monte-Carlo simulation based Finite Element Method study and also with the semi-analytical probabilistic approach. The special purpose numerical implementation of the entire Stochastic perturbation-based Finite Element Method has been entirely programmed in computer algebra system MAPLE 2019 using Runge-Kutta-Fehlberg method. Further usage of the proposed technique to analyze stochastic reliability of the given structure subjected to dynamic oscillatory excitation is also included and discussed here because of a complete lack of the additional detailed demands in the current European designing codes.

Published: March 2021

In this paper, an exact analytical solution for the motion of fractionalized second grade fluid flows moving over accelerating plate under the influence of slip has been obtained. A coupled system of partial differential equations representing the equation of motion has been re-written in terms of fractional derivatives form by using the Caputo fractional operator. The Discrete Laplace transform method has been employed for computing the expressions for the velocity field u(y, t) and the corresponding shear stress τ (y, t). The obtained solutions for the velocity field and the shear stress have been written in terms of Wright generalized hypergeometric function pψq and are expressed as a sum of the slip contribution and the corresponding no-slip contribution. In addition, the solutions for a fractionalized, ordinary second grade fluid and Newtonian fluid in the absence of slip effect have also been obtained as special case. Finally, the effect of different physical parameters has been demonstrated through graphical illustrations.
Effect of Magnetic Field on Thermosolutal Instability of Rotating Ferromagnetic Fluid Under Varying Gravity Field
Authors: Pundir S. K. , Nadian P. K. , Pundir R.
Published: March 2021

This paper deals with the theoretical investigation of the effect of a magnetic field, rotation and magnetization on a ferromagnetic fluid under varying gravity field. To find the exact solution for a ferromagnetic fluid layer contained between two free boundaries, we have used a linear stability analysis and normal mode analysis method. For the case of stationary convection, a stable solute gradient has a stabilizing effect, while rotation has a stabilizing effect if λ>0 and destabilizing effect if λ<0. Further, the magnetic field is discovered to have both a stabilizing and destabilizing effect for both λ>0 and λ<0. It is likewise discovered that magnetization has a stabilizing effect for both λ>0 and λ<0 in the absence of the stable solute gradient. Graphs have been plotted by giving numerical values of various parameters. In the absence of rotation, magnetic field and stable solute gradient, the principle of exchange of stabilities is found to hold true for certain conditions.

Authors: Camargo Juliana , Lima Lycia , Riva Flavio , Souza André Portela
Published: March 2021

This paper describes the results from an evaluation of a public policy that offers scholarships to current and former public high school students, so that they can attend technical and vocational education courses free of charge. We use a waiting list randomized controlled trial in four municipalities in a southern Brazilian State (Santa Catarina) to quantify the effects of the program on school progression, labor market outcomes and non-cognitive skills. Our intention-to-treat estimates reveal substantial gender heterogeneity two years after program completion. Women experienced large gains in labor market outcomes and non-cognitive skills. Employment rose by 21 percentage points (or approximately 33%) and the gains in earnings are of more than 50%. Also, women who received the offer scored 0.5σ higher on the synthetic index of non-cognitive skills and 0.69σ higher on an extraversion indicator. We find no effects on the male sub-sample. These findings corroborate the evidence on gender heterogeneity in the labor market effects of technical and vocational education programs. We also perform a series of exercises to explore potential channels through which these effects arise.
Thermoluminescence Response of AlN+Y2O3 Ceramics to Sunlight and X-Ray Irradiation
Authors: Cipa J. , Trinkler L. , Berzina B.
Published: March 2021

AlN is a wide band gap material with promising properties for dosimetric applications, especially in UV dosimetry. In the present research, the thermoluminescence method is used in order to better understand sunlight and X-ray irradiation effects on yttria doped AlN ceramics. In general, the TL response is characterised by a broad TL peak with maxima around 400–450 K and a TL emission spectrum with UV (400 nm), Blue (480 nm) and Red (600 nm) bands. Compared to the X-ray irradiation, sunlight irradiation creates a wider TL glow curve peak with a maximum shifted to higher temperatures by 50 K.

Furthermore, in the TL emission spectra of AlN irradiated with sunlight the UV band is suppressed. The reasons of the TL peculiarities under two types of irradiation are discussed. Practical application of AlN ceramics as material for UV light TL dosimetry and, in particular, for sunlight dosimetry is estimated.

Published: March 2021

The near-band luminescence of doped ZnO is promising for advanced scintillators; however, the dopant type and concentration effects require a detailed study. Undoped and Ga-doped ZnO nanopowders were prepared by a microwave-assisted solvothermal method and the gallium concentration effect on luminescence properties was studied. The near-band luminescence peak position dependence on gallium concentration was observed. Near-band luminescence intensity versus defect luminescence intensity ratio was explored for different gallium concentrations and the optimal value was determined. Samples were prepared with dopant concentrations between 0.2 and 1.5 at%, XRD analysis confirmed that samples contained only zinc oxide hexagonal wurtzite phase. The results of the research showed that ZnO:Ga containing 0.9 at.% gallium was promising for scintillators.
Perceptions of age in contemporary tech
Authors: Rosales Andrea , Svensson Jakob
Published: March 2021

This article attends to age stereotypes and ageism in contemporary tech. In academia, little attention has been devoted to this topic. Therefore, we intend to initiate a discussion around ageism in tech by studying perceptions of age in the tech industry. Our study is based on interviews with 18 tech workers around the world of varying age. According to our interviewees, tech workers over 35 are considered old in the tech industry. Older tech workers are expected to become managers, thought to become less interested in new technology, and expected to have more challenges when learning new software. We also look at how tech workers of different age groups experience entrepreneurial values of the company as a playground, staying hungry, and changing the future with technology, and how these values influence their professional careers. We conclude that ageism is reinforced in contemporary tech through several stereotypes related to age.
The influence of electron and gamma irradiation on the properties of starch:PVA films – the effect of irradiation dose
Authors: Cieśla Krystyna A. , Abramowska Anna
Published: March 2021

The paper discusses the effect of ionizing radiation on the functional properties of the biodegradable starch:PVA films. The analysis is related to the possible use of the material for packing the products (particularly, food) that are predicted for radiation decontamination and to the potential modification of the material by radiation treatment. Our previous results have shown that the influence of ionizing radiation on the films’ properties varied for the specific compositions (differing in starch:PVA ratio or the type of substrates) and depended on irradiation conditions. However, these studies considered only the irradiation performed in gamma chamber or in e-beam using a dose of 25 kGy. Therefore, the present study deals with the effect of the irradiations performed using various doses on the selected promising starch:PVA composition. The films characterized by starch:PVA weight ratio of 45:55 was obtained by solution casting and irradiated with fast electrons in air and with 60Co gamma rays in nitrogen applying the doses of 5, 10, 20, 25, 30, 50, and 75 kGy. No regular dependence has been noticed between the composition of films (differing in the starch and PVA content) and the intensities of the particular bands in the UV-VIS DRS spectra after irradiation. The results indicated strong interaction of the starch and PVA components in the films and the occurrence of specific reactions in each composition upon irradiation. No special differences were observed between tensile strength and Young’s modulus of the non-irradiated films characterized by the starch:PVA ratio equal to 45:55 and the samples irradiated using doses in the range of 5–75 kGy. Similarly, no differences were observed in both cases between the swelling capability of the non-irradiated and the irradiated films. However, it can be deduced that solubility in water increased when the radiation dose increased. The results show that using the doses till the range 25 kGy does not cause an essential change of all the examined properties of the starch:PVA (45:55) films. Accordingly, starch:PVA (45:55) films might be considered suitable for packing food predicted for radiation decontamination.

Published: March 2021

It is a known fact that phosphate rocks have high levels of natural radioactivity due to the presence of large concentrations of radionuclides. This work aims to estimate radiation exposure and dose levels at Al-Jalamid site in northern Saudi Arabia. Al-Jalamid area is one of the largest reserves of phosphate worldwide. Ma’aden, a Saudi Government public company, owns the mine and is responsible for all mining activities. Phosphate and soil samples collected from Al-Jalamid phosphate mining area have been analysed for their uranium and thorium content by an α-spectrometer using radiochemical techniques. The quantity of radon gas was measured both in groundwater and in the atmosphere (indoor and outdoor) at the site using a portable radiation survey instrument. Groundwater samples collected from wells surrounding the mining area were analysed using a liquid scintillation counter in addition to an α-spectrometer. Finally, it is found that phosphate rock concentrate products cannot be utilized economically based on the standards set by the International Atomic Energy Agency (IAEA), since the average activity concentration does not reach the limit set by IAEA and hence are not commercially feasible.

Published: March 2021

Screen golf is a product of the combination of modern technology and leisure. This new form of sport can provide people with disabilities opportunities for positive life experiences through sport participation. This study aimed to investigate differences in the effect of screen golf participation on psychosocial factors (self-esteem, isolation, depression, loneliness, and life satisfaction) in people with and without disabilities. With 293 survey respondents in this study, the Multivariate Analysis of Variances (MANOVA) was performed twice to measure differences between groups after ensuring the validity and reliability of the instrument. Participation in screen golf demonstrated a positive effect for all factors for people with disabilities. Results also showed a more positive effect on self-esteem and life satisfaction for people without disabilities with screen golf experience than for those without any screen golf experience. This study demonstrated that screen golf, as a physical leisure activity, was helpful to all study participants, with greater positive effects observed for participants with disabilities. This finding suggests that ubiquitous leisure activities such as screen golf made possible by advancements in modern technologies offer desirable benefits to many. This study is highly meaningful since it demonstrated how technologies could be helpful to people with disabilities who historically have has less access to leisure activities than able-bodied people.

Authors: Tułacz Kinga , Wierzbicka Barbara , Berghausen-Mazur Marta
Published: March 2021

Aim. The purpose of the paper was to determine the type of concerns of pregnant women and women in childbed during the announced state of pandemic in the country.

Material and methods. The study included a group of 102 women, including 87 (85.3%) pregnant women and 15 (14.7%) puerperal women. A self-written questionnaire containing 18 questions was used for the study. The comparison of the values of the qualitative variables in the groups was performed using the chi-square test or Fisher’s exact test. The statistical analysis was performed in the R program, version 4.0.22.

Results. In the study group, the respondents’ greatest fear was childbirth without an accompanying person. A frequent cause of concern among the respondents was the limitation of follow-up visits to the doctor or midwife providing prenatal care. Limited physical activity during the pandemic also turned out to be a significant concern. Only 11.8% of the respondents did not feel any fear in their current pregnancy. Additionally, among the reasons for their concerns, the respondents mentioned, among others: fear of separation of mother and child after delivery, the need to care for an older child, no visits to specialists, fear of infection with SARS CoV-2 virus. Statistical analysis confirmed a significant correlation between the number of children already owned and the concerns of pregnant women regarding being resourceful in caring for themselves and their child after returning home.

Conclusions. The duration of the pandemic is a significant stress factor for a pregnant woman. A significant group of female respondents was concerned about the deterioration of maternity care and infection with the virus during hospital stay. Therefore, the task of medical personnel is to provide mental support and educate patients.

Published: March 2021

Introduction. Spirituality has a multi-dimensional nature which influences the professional activities of nurses in a caring profession.

Aim. Identifying selected determinants of spirituality among nurses and their relationship with socio-demographic factors.

Material and methods. Research was conducted in 2018 on 144 nurses. All of the respondents were active in their profession. The research was made with diagnostic survey method using standardized research tools, including a Self-Description Questionnaire (SDQ), the Spiritual Transcendence Scale (STS), and the Brief Religious Coping (RCOPE) questionnaire, (BR).

Results. It was established that age and professional seniority positively correlate with Religious Attitude (SDQ), p<0.05; Transcendence Proper (STS), p<0.01; and with positive religious stress-coping strategies (BR), p<0.01. It shows that a declaration of relationship to faith positively correlates with the subscales of the questionnaire (SDQ), i.e. Religious Attitude (r=0.247, p<0.01), Ethical sensitivity (rho=0.230, p<0.01), and Harmony (r=0.218, p<0.05). Moreover, a strong correlation was confirmed with Transcendence Proper (STS), r=0.40, p<0.01, and with positive religious strategies for coping with stress (BR), r=0.505, p<0.01, and declared relationship to faith.

Conclusions. The dimensions of spirituality are significantly related to age, seniority, declaration of attitude to faith, and positive religious stress-coping strategies. Predictors of spirituality among nurses are place of residence, spiritual openness and negative religious stress-coping strategies.

Published: March 2021

The incidence of hypopharyngeal cancer globally is about 0.8 per 100 000. Globally, approximately 38 000 cases of head and neck cancer are considered yearly to be high-risk human papillomavirus (HR-HPV) related. Biopsy material fixation in formalin and embedding in paraffin (FFPE) creates many challenges. The extraction of nucleic acid material requires a more complicated approach, and often the extracted DNA is fragmented. The aim of the study was to compare several HR-HPV detection methods in nucleic acid material extracted from FFPE samples. The extracted DNA was analysed with different molecular biology methods to assess DNA quality and to determine the presence of HPV DNA with various HPV detection systems. The results were compared and statistically analysed. There was good agreement between two real-time PCR methods — Anyplex II HPV28 and Sacace HPV High-Risk Screen Real-TM Quant. We failed to reach a conclusion on agreement between real-time PCR methods and HPV16 type-specific primer PCR. There was moderate positive correlation between Anyplex II HPV28 semiquantitative results and Sacace quantitative results. We suggest that real-time PCR assays detecting smaller DNA amplicons are good and reliable methods for detecting HPV genetic material in FFPE samples.
Right Ventricle Involvement in Patients with Acute ST Elevation Myocardial Infarction: Is Echocardiography Good Enough in Diagnosing It?
Authors: Pičkure Žanna , Kalinin Artem , Lejnieks Aivars
Published: March 2021

Right ventricle (RV) dysfunction in patients with ST elevation myocardial infarction (STEMI) is more common and important than previously considered. The aim of this study was to determine the incidence of RV involvement in acute STEMI by using advanced echocardiography (Echo) methods, such as RV longitudinal strain and three-dimensional (3D) ejection fraction, and to prove that RV involvement is not exclusive to right coronary artery damage in STEMI. The study group was formed of 73 patients aged 30 to 60 years with confirmed first-time acute STEMI and coronary angiography performed. Abnormality thresholds for standard and advanced Echo parameters in case of STEMI for predicted RV dysfunction were RV 3D ejection fraction < 49% and RV free wall longitudinal strain > –24.5 %. Using these abnormality thresholds it was possible to detect RV dysfunction in 60% of STEMI cases. The acquired results are close to the cardiac magnetic resonance data found in literature, which is the gold standard for determination of RV systolic function. RV involvement did not depend on the damaged coronary artery, as there was no association detected (p = 0.09); therefore, RV function should be assessed in every STEMI patient, and Echo is an effective method for this purpose.

Published: March 2021

Based on epidemiological data, osteoarthritis (OA) is the most common joint disease of populations of industrialised countries. The increasing prevalence of OA is closely related to an ageing population and a sedentary lifestyle. Load-bearing joints, such as hip, knee, and intervertebral joints, are the primary ones that are being subjected to the degenerative changes. The patho-physiology of the disease is based on progressive damage and gradual deterioration of the micro and macrostructure of hyaline cartilage. In today’s radiological practice, the first-line method for assessing the condition of articular cartilage is magnetic resonance imaging (MRI). However, the sensitivity of standard clinical MRI in articular cartilage assessment is limited. For this reason, for the last five years there has been a rapidly growing interest in developing advanced MRI techniques for cartilage structure evaluation. The purpose of this pilot study was to highlight the possibilities of Artificial Intelligence Computed Vision Analysis (MEDH 3.0 algorithm) in the evaluation of cartilage changes of the knee joint. The study was carried out at Rīga East Clinical University Hospital (RAKUS) and included 25 patients. After assessment by a rheumatologist, the participants were divided into two groups: 15 (60%) participants with OA and 10 (40%) healthy individuals. All patients underwent MRI examinations according to a unified RAKUS Gaiïezers Radiology clinic protocol. MRI data were analysed using the Computed Vision Analysis MEDH 3.0 algorithm. The results showed substantial differences in intensity variance (p < 0.01) parameters, as well as in pixel entropy and homogeneity values (p < 0.01). The results of the pilot study confirmed the potential use of Artificial Intelligence Computed Vision Analysis in further development and integration in the assessment of cartilage changes in the knee joint.

Published: March 2021

Present geological and geomorphological objects are non-living features that can enhance curiosity and increase the knowledge of Earth's history, through the development of geotourism. The municipality of Durrës, located in western Albania represents an active tectonic area with numerous landforms, an evidence of geodiversity and geoheritage. In this paper, the most typical geosites are identified mainly based on their scientific values as well as their geotourism potential. After the defining of 5 geosites, through geological and topographical map, we applied the Geosite assessment model (GAM). GAM is widely used in Europe on different areas and has given good results in the evaluation of geosites. The GAM method involves only experts’ opinions, which are essential for the preliminary development of geotourism in Albania. This method produce different main values (MV) and additional values (AV) score, which are very useful results in preservation, conservation and promotion of the area.

Published: March 2021

BACKGROUND. The relationship between the maxillary sinus floor and the roots of the teeth in the upper arch is essential, especially in the correct diagnosis and treatment of odontogenic maxillary sinusitis. The aim of this study was to determine exactly this distance and to observe the most common teeth situated closely to the maxillary sinus.

MATERIAL AND METHODS. The study was performed in 2020, in the ENT Department of “Sfanta Maria” Hospital, and was made based on computed tomography (CT) scans of the sinuses from the clinic’s archive. The image analysis was performed with a radiologic software. For each tooth, from both right and left upper hemiarcade, the distance between the dental root and the bony floor of the maxillary sinus was measured and the average distances were compared.

RESULTS. Among the present teeth analysed, those with the closest distance were the 1st M (95.15% on the right side and 96.23% on the left side), then the second molars (96.08% on the right side and 90% on the left side). The 2nd and 3rd PM had a similar percentage of the sinusal approach, which varied between 82% and 86%.

CONCLUSION. Knowing these dento-sinusal relationships, there is a win-win situation for both the ENT doctor and the dentist. The paraclinical examination necessary for the analysis of the dento-alveolo-sinusal relation and of the afferent pathology is the imaging one, of choice being the CT and CBCT scans.

Authors: Loučanová Erika
Published: March 2021

At the present time, a great attention is paid to the ecological innovation, which represents innovation characterization to any ecological change with a positive impact on consumers. Such innovations increase the comfort for consumers and concurrently they represent more effective, more economic, ecological, healthier and safer solutions. Ecological innovation represents any innovation aimed at significant and visible progress towards the goal of sustainable development. This is done by reducing the impact on the environment or achieving a more efficient and responsible use of natural resources, including energy and Zero waste. The aim this paper is evaluation to the perception of Zero waste in the context of ecological innovations in Slovakia. The research is carried out using the Kano model. The results point to the importance of addressing the issue of ZeroWaste, encouraging friends to buy in non-packaging stores and creating a stimulation of advertising to buy products in a non-packaging store. Other attributes of the given issue are perceived by Slovak respondents in the opposite way or have no influence on them. Therefore, it is important to provide sufficient information on this issue and to educate the population in order to increase their interest in this issue and to start behaving responsibly towards waste management.

Vehicular queue length measurement is an important parameter to detect the traffic congestion, which is resulted from several issues such as traffic lights, accidents, and poor roads infrastructures. In this paper, a system in real-time is proposed to detect and measure the vehicular queue length at intersections. The proposed system consists of two main steps: the first step is the detection of queue by using frames differencing method to detect the motion in the target areas. If there is no a motion, then the second step is implemented to detect the vehicles in these areas by using Single Shot Multibox Detector (SSD) algorithm. If there are vehicles, that means the queue exists and the measurement process begins. Some modifications are applied on SSD algorithm to fit with in our system and to improve the accuracy of the vehicle detection process. The system is applied on videos obtained by stationary cameras. The experiments demonstrate that this system is able to accurately detect and measure the vehicular queue length.

Published: March 2021

I föreliggande rapport presenteras resultatet av effektutvärderingen av pilotprojektet Sluta skjut – tillsammans för ett tryggt Malmö. Utvärderingen har genomförts på uppdrag av Brottsförebyggande rådet (Brå) med stöd från Brå och Fonden för inre säkerhet (ISF). Tidigare har enprocessutvärdering publicerats. Den grova våldsbrottsligheten beskrivs som ett av de största samhällsproblemen i Sverige idag och efterfrågan på effektiva åtgärder som kan minska våldet är stor. Sluta skjut bygger på en amerikansk strategi, Group Violence Intervention, som i flera studier visat på positiva resultat när det gäller att minska det allra grövsta våldet. I processutvärderingen av Sluta skjut studerades om det går att tillämpa en amerikansk modell i en svensk kontext. I effektutvärderingen har vi studerat om insatsen lett till minskat antal skjutningar i Malmö. Svensk forskning om vad som fungerar för att minska det grova våldet är begränsad och det behövs mer kunskap för att brottsförebyggande aktörer ska få de verktyg de behöver för att vända utvecklingen.

A flow-map model for analyzing pseudothresholds in fault-tolerant quantum computing

Published: March 2021

An arbitrarily reliable quantum computer can be efficiently constructed from noisy components using a recursive simulation procedure, provided that those components fail with probability less than the fault-tolerance threshold. Recent estimates of the threshold are near some experimentally achieved gate fidelities. However, the landscape of threshold estimates includes pseudothresholds, threshold estimates based on a subset of components and a low level of the recursion. In this paper, we observe that pseudothresholds are a generic phenomenon in fault-tolerant computation. We define pseudothresholds and present classical and quantum fault-tolerant circuits exhibiting pseudothresholds that differ by a factor of $4$ from fault-tolerance thresholds for typical relationships between component failure rates. We develop tools for visualizing how reliability is influenced by recursive simulation in order to determine the asymptotic threshold. Finally, we conjecture that refinements of these methods may establish upper bounds on the fault-tolerance threshold for particular codes and noise models.
A new algorithm for fixed point quantum search
Authors: Tulsi T. , Grover L.K. , Patel A.
Published: March 2021

The standard quantum search lacks a feature, enjoyed by many classical algorithms, of having a fixed point, i.e. monotonic convergence towards the solution. Recently a fixed point quantum search algorithm has been discovered, referred to as the Phase-\pi/3 search algorithm, which gets around this limitation. While searching a database for a target state, this algorithm reduces the error probability from \epsilon to \epsilon^{2q+1} using q oracle queries, which has since been proved to be asymptotically optimal. A different algorithm is presented here, which has the same worst-case behavior as the Phase-\pi/3 search algorithm but much better average-case behavior. Furthermore the new algorithm gives \epsilon^{2q+1} convergence for all integral q, whereas the Phase-\pi/3 search algorithm requires q to be (3^{n}-1)/2 with n a positive integer. In the new algorithm, the operations are controlled by two ancilla qubits, and fixed point behavior is achieved by irreversible measurement operations applied to these ancillas. It is an example of how measurement can allow us to bypass some restrictions imposed by unitarity on quantum computing.
Characterizations of symmetric monotone metrics on the state space of quantum systems
Authors: Hansen F.
Published: March 2021

The quantum Fisher information is a Riemannian metric, defined on the state space of a quantum system, which is symmetric and decreasing under stochastic mappings. Contrary to the classical case such a metric is not unique. We complete the characterization, initiated by Morozova, Chentsov and Petz, of these metrics by providing a closed and tractable formula for the set of Morozova-Chentsov functions. In addition, we provide a continuously increasing bridge between the smallest and largest symmetric monotone metrics.
