Two-dimensional radiographs versus cone-beam computed tomography in planning mini-implant placement: A systematic review

Background This study aimed to compare two-dimensional radiographs and cone beam computed tomography (CBCT) images for mini-implant planning. Material and Methods A search was performed in PubMed, Embase, Web of Science, Cochrane Library and Google Scholar electronic databases according to PIRD strategy, on September 11, 2021. In vivo studies that compared two-dimensional imaging with CBCT for mini-implant planning were selected. The methodological quality of each study was assessed using the QUADAS-2 tool. Results The initial search identified 441 papers. Five studies were added following a manual research. Of the total 446 studies, 40 were selected after title evaluation, 29 remained after abstract evaluation, and 11 were left after full-text analysis. Final screening yielded a total of four studies that composed the narrative synthesis of this systematic review. When comparing the imaging systems for palatal mini-implants, lateral radiographs (LRs) showed approximately the same measurements of bone quantity as those of CBCT, hence bearing no influence on placement site selection. In determining image suitability for interradicular mini-implants, two-dimensional radiographs underestimated the available space. Conclusions Lateral radiography is sufficient to quantify the available bone for planning mini-implants installed on the palate, in the median region of upper first premolars. CBCT enhances interradicular mini-implant planning by aiding in implantation site selection, and improving the installation success rate.

Light-induced effects against Candida albicans and Staphylococcus aureus

Objectives: The present study evaluated the action of LED light sources at different wavelengths on cell viability, lipid peroxidation, and Top I and II gene expression of Candida albicans and Staphylococcus aureus. Methods: Planktonic cultures were subjected of illumination, and the post- irradiation cell proliferation was assessed by quantification of metabolic mitochondrial activity. Next, the response of the microorganisms to the treatments was assessed. Results: Cell viability (CFU/mL) reduction occurred only for the fungus by 0.5 and 0.6 log10 using yellow LED 0.1 and 10 J/cm2, respectively. For S. aureus, none of the evaluated wavelengths reduced cell viability versus the control. Production of intracellular ROS occurred in all tested light doses and wavelengths, except for 0.1 J/cm2 of yellow LED for both microorganisms. Lipid peroxidation occurred only for C. albicans after exposure to 10 J/cm2 of yellow LED, 15 and 50 J/cm2 of blue LED, and 300 and 500 lux of white LED. The two doses of blue light and red light decreased the expression of TOP II of C. albicans and TOP I of S. aureus. The two doses of yellow and white lights promoted an increase in the expression of the genes that encode TOP II and TOP I for both species. Conclusion: The results demonstrated that the mechanisms of action of white LEDs and at blue (455 nm), red (660 nm) and yellow (590 nm) wavelengths seem to be related to the production of ROS, lipid peroxidation, and DNA damage.
Adsorption Kinetic and Isotherm Studies of Reactive Red B Textile Dye Removal Using Activated Coconut Leaf Stalk

Textile wastewater has become one of the serious environmental problems due to containing a high concentration of chemicals with extreme color intensity. Reactive red RB is among the synthetic azo dyes commonly used as a textile colorant with their property are very difficult to degrade naturally. This research was focused on studying the kinetic behavior, and adsorption isotherm of reactive red RB textile dye on coconut leaf stalk activated carbon (CLSC). Coconut leaf stalk carbon was activated using sulphuric acid and sodium hydroxide. It was investigated in terms of chemical functional groups, surface morphology, carbon content, ash content, and adsorption efficiency of reactive red RB textile dye under various conditions of initial pH, incubation time, and dye concentration. The results showed the maximum adsorption efficiency of reactive red RB dye with a concentration dye of 60 mg/l onto CLSC surface activated by sulfuric acid and sodium hydroxide in an experiment carried out at pH 5 for 120 min were 88.73% and 64.27%, respectively. The adsorption isotherm of reactive red RB on the CLSC surface follows the Langmuir isotherm model, which shows that the adsorption process occurs monolayer. In contrast, the adsorption kinetics correspond to pseudo-second-order.
Effects of neural mobilization in the treatment of chronic low back pain: a systematic review

Introduction: Low back pain appears in approximately two thirds of the population at some point in life and when it exceeds more than 12 weeks, it evolves to chronic low back pain. Chronic low back pain is considered one of the most common causes of disability and absence from work. A therapeutic technique that can be used as a treatment for chronic low back pain is neural mobilization, capable of restoring compromised neurological structures, restoring movement by improving the elasticity of neural tissue and adjacent tissues. Objective: To verify the effects of neural mobilization in patients with chronic low back pain. Material and methods: All articles were carefully evaluated in order to obtain concrete and reliable information. The databases used were Google Scholar, Scielo, Medline and PubMed due to the methodological quality and articles in the area of interest. The keywords “low back pain”, “chronic low back pain”, “neural mobilization” and “physiotherapeutic intervention” were combined in the most diverse possibilities, in English and Spanish translations. Results: 86 articles were found, nine of which were included in this review. They had a score ≥ 5 on the PEDro Scale, which methodologically qualifies the articles. After analyzing the results obtained through the selected articles, all the data collected, as well as their respective results, were described in a table that contains data from the articles. Conclusions: Neural mobilization reduces pain and improves the extensibility of tissues, causing a reduction in painful sensation and increased flexibility. Therefore, it is necessary to continue research in order to verify new results obtained through this type of intervention.

Sir,Several recent reviews have detailed how CTX-M b -lactamases have become dominant among extended-spectrum b -lactamase (ESBL)-producing Enterobacteriaceae (ESBL-PE) in many European countries; 1,2 however, data from Ireland were lacking. This study represents a nationwide survey of ESBL-PE collected throughout Ireland over an 11 year period and highlights the pre-dominance of CTX-M-producing strains.
Occurrence of Enterobacteriaceae in medicinal plants sold in local markets of Savar, Dhaka

Medicinal plants can be contaminated with a large diversity of potentially pathogenic bacteria. Ten medicinal plant samples Plantago psyllium, Terminalia bellirica, Terminalia chebula, Phyllanthus emblica, Ocimum basilicum, Glycyrrhiza glabra, Withania somnifera, Andrographis panicula, Bombax ceiba were collected from Amin Bazar and Savar of Savar area to study the presence and abundance of Enterobacteriaceae family bacteria in the herbal plant samples. A total of fifty five (55) bacterial isolates have been isolated from different medicinal plant samples using spread plate method on nutrient Agar media. Culture of bacterial isolate on a number of selective and differential media and biochemical tests (Catalase activity, hemolytic property, fermentation test, Starch hydrolysis, VP test, MR test, MIU test, Indole and casein test etc.) revealed the presence of different Enterobacteriaceae family bacteria in the plant samples. Out of 55 isolates 6 isolates were Salmonella sp. (11%), 2 isolates were Klebsiella sp. (3.63%) and 2 isolates were Enterobacter sp. (3.63%). Antibiotic sensitivity test of bacterial isolates showed that all the identified Enterobacteriaceae family bacteria were sensitive to Kanamycin but resistant to Amoxycilin, Aztreonam and Penicillin-G. Therefore, this study highlighted the necessity for constant quality assessment of herbal medicines to facilitate and ensure safe production and supply of medicinal products suitable for human consumption.

Targeted Monetary Policy, Dual Rates and Bank Risk Taking

We assess whether central bank credit operations influence the size and composition of bank credit in a negative interest rate environment. We exploit conﬁdential information from the newly established European credit registry to capture bank lending conditions and bank risk-taking. For identiﬁcation, we use high-frequency reactions of bank bonds around the announcement of the April 2020 recalibration of the ECB’s Targeted Longer-Term Refinancing Operations (TLTROs). We find that the credit easing measures had a strong positive effect on bank credit, even when controlling for possible confounding factors. The increase in lending was not accompanied by excessive risk-taking, especially for banks with low intermediation margin, that is, those that were poised to beneﬁt the most from TLTROs’ borrowing rates below the interest rates on central bank reserves.
Identification And Suitability Of A Non-anthropomorphic Meta-language Framework In Military Applications

Humans carry mental models concerning the behaviors, looks, and operation of products, tools, and items used in their daily lives. When these items do not fit a user’s conceptual model confusion and inefficiency occur. There are four basic types of mental models based on interactive activities: 1) instructing, 2) conversing, 3) manipulating and navigating, and 4) exploring and browsing. This thesis will focus on the conversing conceptual model and its application to communications between human-agent teams to best fit a user’s mental model for that communication. A non-anthropomorphic framework does not exist for use in military applications such as; target detection, nuclear, biological, and chemical agent detection, and explosive ordinance disposal. As agents become increasingly autonomous and complex in the currently military working environment an effective and un-confusing non-anthropomorphic meta-language framework must be explored and developed to fulfill the need for human-agent communications. The meta-language framework may consist of visual and audio cues as pose, motion, color, and non-speech sounds. This thesis will attempt to identify and evaluate a non-anthropomorphic framework of communications between human-human, human-agents, and agent-agent teams that will maximize the effectiveness of the communications in terms of efficiency and interpretation.
Position-Aware Neural Attentive Graph Networks for Multi-hop Question Answering

Recently there has been considerable interest in applying graph neural networks (GNN) to multi-hop question answering (QA) tasks, as graph representations can explicitly express rich dependencies in language. However, graph representations su ﬀ er from the loss of sequential information and the di ﬃ culty of representing global semantic information. In this work, we propose the query-attention mechanism to enhance the GNN-QA system by utilizing both global and local contextual information. We also explore injecting the positional information into the graph to complement the sequential information. Our experiments are conducted on the WikiHop dataset to allow direction comparison with Entity Relational-Graph Convolutional Networks (De Cao et al., 2019). Our contributions identify the existence of position bias in the dataset and our experiment results with ablation study conﬁrms that our proposed modules improve the generalization accuracy by 1.43%.
Effects of Basicity and Mesh on Cr Leaching of EAF Carbon Steel Slag

The slag’s chromium leaching is one of the most pressing concerns in Electric Arc Furnace (EAF) carbon and stainless steels production. In recent years, many studies have aimed at understanding which properties (basicity, cooling speed) and phases (spinels, wustite, silicates) determine the Cr leaching, defining different indices (sp-factor, cs-factor) in order to forecast the slag’s behavior compared to the leaching of this toxic metal. The literature suggests that spinel formation is usually a good way to fix Cr and prevent its leaching. However, in some conditions (high basicity, low amount of spinel-forming species) soluble Cr-bearing phases can be formed, i.e., Ca-chromite or unstable spinel. In these conditions, Cr can be leached easily, even if it is bound in a spinel structure. In this paper, the effects of basicity and impurities (Ca, Si) on the instability of Cr-spinel was investigated, with respect to slag mesh. The influence of basicity was also studied on Mg-wustite stability, which might contribute to the leaching of Cr. Different samples of carbon steel slag, suspected of forming unstable spinels, belonging to different steel grade production, were also investigated. Both granulated (4 mm) and milled (<100 μm) slag were analyzed. Scanning Electron Microscopy coupled with Energy Dispersive Spectroscopy (SEM-EDS) analyses were carried out to measure the local chemical composition of Cr-bearing phases. This data was correlated with slag basicity (by X-Ray Fluorescence: XRF), spinel fraction (by X-Ray Diffraction: XRD), and Cr leaching (by Inductively Coupled Plasma Mass Spectrometry: ICP-MS). The main results indicate that the increase of the slag basicity implies an increase of the impurity content (Ca, Si) in the spinel, also over-saturated by Cr. This aspect, coupled with spinel geometrical features, seems to justify the unexpected Cr leaching of some slag samples. Basicity does not influence the chemistry of wustite, thus excluding it as an additional Cr leaching source.
The effect of market conditions on the ability of the capital asset pricing model “CAPM” to explain the change in stock returns

The purpose of this study is to determine the effect of the stock market conditions, at different estimation periods for capital asset pricing model (CAPM) variables, on the ability of the CAPM to explain the change in stock returns, applied to the Egyptian stock market . Where the researcher assumes that the different levels of market return (low - high) may affect the ability of the capital asset pricing model to explain the change in the stock returns. Especially most of the literary reviews of the capital asset pricing model were not exposed to the conditions of measuring the returns. That is the approach of the present study was to test the theory of capital asset pricing model at a different level of market return at a different basis of estimation periods of capital asset pricing model variables (6,12 months) . Because the Egyptian stock market is one of the emerging markets, the study of CAPM ability, to predict stock returns at a different level of market return (low - high) is critical . This study is based on a different approach represented in testing the ability of the capital asset pricing model to explain the change in the stock returns according to a different level of the market return . The EGX30 index was used as the most important indicator to measure the market index. 70% of the strongest stocks within the index were selected for the study tests during the period from 01/01/2009 to 31/03/2015. the relationship between portfolios calculating may beta relationship according results of in stock exchanges AMEX, no significant relationship between and expected return. on the Stock Exchange positive relationship between beta and expected no clear direction of the of systemic on the performance of the Egyptian securities portfolio to for Egyptian investments. significant relationship between systematic and
CNN-Based Audio Recognition in Open-set Domain

This paper presents a method that uses convolutional neural networks for audio recognition in an open-set scenario. The audio sounds in an open-set scenario are usually out of the training data distribution, which necessitates a model that can recognize the known classes while rejecting the unknown ones. We propose a convolutional approach for recognizing audio events, that can effectively address open-set recognition by adding inclusion probabilities of extreme value machines. Extensive experiments conducted showed that our proposed method outrivals representative existing methods under the open-set regime.
Best‐Practice DFT Protocols for Basic Molecular Computational Chemistry

Abstract Nowadays, many chemical investigations are supported by routine calculations of molecular structures, reaction energies, barrier heights, and spectroscopic properties. The lion's share of these quantum‐chemical calculations applies density functional theory (DFT) evaluated in atomic‐orbital basis sets. This work provides best‐practice guidance on the numerous methodological and technical aspects of DFT calculations in three parts: Firstly, we set the stage and introduce a step‐by‐step decision tree to choose a computational protocol that models the experiment as closely as possible. Secondly, we present a recommendation matrix to guide the choice of functional and basis set depending on the task at hand. A particular focus is on achieving an optimal balance between accuracy, robustness, and efficiency through multi‐level approaches. Finally, we discuss selected representative examples to illustrate the recommended protocols and the effect of methodological choices.
Exploring the Use of Occupational Therapy Telehealth Services in Early Intervention During COVID-19

During the COVID-19 pandemic, the use of telehealth has increased significantly, including for occupational therapy (OT) services provided in the early intervention (EI) setting. While preliminary research evaluates the effectiveness and benefits of telehealth services in early intervention occupational therapy (EI OT), few studies compare telehealth to traditional inperson services. The purpose of this research study is to understand experiences with telehealth for EI OT services during COVID-19 as compared to experiences with previous in-person services from the perspective of OTs and parents. Using a qualitative case study design, interviews were conducted with one EI OT practitioner and two of their patient families. Major results identified using thematic content analysis include positive aspects of telehealth, such as increased access to the service provider, flexibility, and limited exposure to illness in general, as well as challenges to the use of telehealth, including significant safety concerns and problems associated with the lack of physical interaction and in-person services, resulting in perceived ineffectiveness of telehealth for specific EI OT services, dependent on the type of service. These findings add to existing research by identifying aspects of telehealth services that need to be considered by EI OTs when evaluating whether telehealth is an appropriate form of service delivery, as well as identifying aspects that may need to be adapted in order to increase feasibility and safety of telehealth services.
PSYCHOLOGICAL NEED SATISFACTION AT WORK

Self-determination theory (SDT) posits universality without cross-cultural uniformity of the three basic psychological needs (autonomy, competence, and relatedness) which have been associated with desirable job outcomes. Yet these promising directions in theory and research have not been extended to Indigenous samples and different occupational types. This is unfortunate as Indigenous peoples globally remain the most disadvantaged on all socio-economic indicators, including employment. This study adopted a strengths-based approach to investigating associations between SDT’s need satisfaction and job outcomes in Australian Indigenous and non-Indigenous professionals and non-professionals. Participants included 1146 Indigenous (48.8%) and nonIndigenous Australians (39.1% men), aged 18-81 years (Mage=43.54). Structural equation modelling (SEM) revealed that autonomy and competence need satisfaction were associated with multiple positive work outcomes and less job ambiguity, whereas satisfaction of the need for relatedness was associated with increased job satisfaction and greater resilience in the workplace. Moderation by Indigenous status and occupation type revealed few differences in the direction and strength of the associations between need satisfaction and job outcomes. However, non-professionals reported significantly lower satisfaction of all three needs, and Indigenous participants reported significantly lower levels of autonomy need satisfaction. As need satisfaction was shown to be equally beneficial for all workers regardless of culture or occupation type, these findings highlight the need for employers to invest more in cultivating the need satisfaction of their Indigenous and nonprofessional staff. Overall, the results extend upon previous research by demonstrating that SDT is generalizable to an Australian Indigenous population and that workplace need satisfaction is important for Indigenous and non-professional employee outcomes.
Qualidade de vida em pacientes coronariopatas

Este estudo comparou as medidas de qualidade de vida (QV) entre 49 sujeitos com infarto do miocardio (IM) e 27 com angina pectoris (AP), atendidos em ambulatorio em um hospital universitario. Os dados foram obtidos por meio da aplicacao de um questionario para levantamento de dados sociodemograficos e clinicos e do instrumento SF-36 para avaliacao da QV. Constatou-se, em ambos os grupos, comprometimento da QV nas dimensoes: aspectos fisicos, dor, estado geral de saude, vitalidade, aspectos sociais e saude mental. Variaveis sociodemograficas e clinicas foram associadas com menores escores de QV em diferentes dimensoes. Estudos futuros devem ser conduzidos, visando a ampliacao do tamanho da amostra, e a compreensao da magnitude do efeito destas variaveis sobre a QV do coronariopata.
Analysis of Government Expenditure and Economic Growth in Nigeria

: This study examines the impact of government expenditure on economic growth in Nigeria using time series data spanning from 1980-2020. Variables used includes real gdp, government final consumption expenditure and population growth rate. Augmented Dickey Fuller and Philips-Perron unit root test for stationary of the variable, Johansen Co integration, Vector Error Correction and Granger Causality tests were estimated. Johansen co integration test result indicates the existence of long run relationship while the error corrections model reveals the absence of shot run relation among the variable. Unidirectional causality runs from population growth to economic growth and public expenditure to population growth. Base on the findings, it is recommended that Nigerian government should enhance expenditure on social welfare to improve standard of living of it citizenry
