Authors: Seada Mervat A. , Hamza Amal M. 
Published: March 2023

Abstract
Background
The lesser grain borer Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae) is a cosmopolitan insect pest of stored cereal grains. In this study, the fine morphology of antennae, maxillary and labial palpi as well as the typology, morphology and distribution of associated sensilla were comprehensively examined by scanning electron microscopy.

Results
On antennae, six types of sensilla were identified, s. trichodea, s. chaetica, two subtypes of s. basiconica, s. ampullacea and s. styloconica, in addition of Böhm's sensilla (Bs). Sensilla trichodea and basiconica were the most abundant sensilla types in the club flagellomeres. Mouth parts of R. dominica were adapted for chewing; maxillary and labial palpi consisted of four and five segments, respectively. Galea of maxilla was two segments, the distal one ended with a brush like organ composed of a dense field of long s. basiconica. The sensilla of maxillary and labial palpi were long and short s. trichodea, s. basiconica, s. styloconica and s. ampullacea. Only one big sensillum digitiformium was found on the lateral side of the distal segment of the maxillary palp.

Conclusions
We summarized the validated structures of different types of sensilla on antennae and palpi of R. dominica and proposed the potential functions of them in detection of ecologically relevant stimuli.

AbstractRapid technological advancement is underway in the sphere of material science research. Several studies have been undertaken around the globe over the last four decades to improve the strength and durability performance of concrete. As a result of ongoing research and experimentation, concrete no longer just consists of the traditional materials of cement, aggregates and water but has transformed into an engineered custom material with efficient new ingredients in order to meet the demands of the expanding construction industry. In this experimental study, biomedical waste incinerator ash (BMIA) was employed as a partial substitute for cement in self-compacting concrete (SCC), designed for M30 grade. BMIA was partially replaced with cement in proportions of 0%, 5%, 10%, 15% and 20% by cement weight. This experimental work aimed to study the fresh, mechanical and durability characteristics of the SCC mixes incorporating BMIA. A suitable super-plasticizer was used to retain the rheological qualities of fresh concrete. To investigate the mechanical and durability characteristics, experiments on hardened concrete were performed. The results demonstrate that 5% of BMIA substitution for cement in the SCC mix had higher strength compared to all other mixes because BMIA’s fine particles filled the voids in the hardened concrete. Scanning electronic microscopy (SEM) and X-ray diffraction (XRD) analyses were performed to examine the microstructure of BMIA substituted SCC versus conventional SCC mix. The chemical composition test revealed that BMIA can be employed in the SCC mix up to 5% efficiently, which will result in waste utilisation and disposal.

PURPOSE Achieving a pathological complete response (pCR) to neoadjuvant chemotherapy (NAC) is associated with improved patient outcomes in triple-negative breast cancer (TNBC). Currently, there are no validated predictive biomarkers for the response to NAC in TNBC. We developed and validated a deep convolutional neural network–based artificial intelligence (AI) model to predict the response of TNBC to NAC. MATERIALS AND METHODS Whole-slide images (WSIs) of hematoxylin and eosin–stained core biopsies from 165 (pCR in 60 and non-pCR in 105) and 78 (pCR in 31 and non-pCR in 47) patients with TNBC were used to train and validate the model. The model extracts morphometric features from WSIs in an unsupervised manner, thereby generating clusters of morphologically similar patterns. Downstream ranking of clusters provided regions of interest and morphometric scores; a low score close to zero and a high score close to one represented a high or low probability of response to NAC. RESULTS The predictive ability of AI score for the entire cohort of 78 patients with TNBC ascertained by receiver operating characteristic analysis demonstrated an area under the curve (AUC) of 0.75. The AUC for stages I, II, and III disease were 0.88, 0.73, and 0.74, respectively. Using a cutoff value of 0.35, the positive predictive value of the AI score for pCR was 73.7%, and the negative predictive value was 76.2% for non-pCR patients. CONCLUSION To our knowledge, this study is the first to demonstrate the use of an AI tool on digitized hematoxylin and eosin–stained tissue images to predict the response to NAC in patients with TNBC with high accuracy. If validated in subsequent studies, these results may serve as an ancillary aid for individualized therapeutic decisions in patients with TNBC.

Published: March 2023

IntroductionIn the era of Covid 19 pandemic, the audio-visual contents of YouTube™could be an information source for dental students, practitioners, and patients. The aim of this study was to evaluate the quality, content, and demographics of YouTube™videos about pediatric dentistry for the education of dentistry students.Materials and methodsA search on YouTube™was performed using the keywords "pediatric dentistry”, “pediatric dental treatments”, “primary teeth treatments" in Turkish. The first 50 videos selected for each keyword were evaluated. Parameters of the videos such as the number of views, the days since the upload, the duration of the video, and the number of likes and dislikes were recorded. Videos are categorized by upload source and content categories as an academic, dentist, physician, patient, reporter, and other, and average points are obtained for the Journal of American Medical Association (JAMA) benchmark. The normality of the data was evaluated with the Shapiro-Wilk test. The data were not distributed normally, compared with the Kruskal Wallis test between source and content groups. The Dunn’s Post Hoc was used to determine to find out which group caused the difference. The Spearman Correlation coefficient was calculated to assess a possible correlation between JAMA, GQS, and VPI scores. All significance levels were set at 0.05.ResultsThe duplicates and non-related ones were removed from 150 videos and remaining 119 videos were evaluated. Most of the videos were uploaded by the dentists and other categories, and mainly the videos were uploaded for patient education. JAMA score was 1 out of 4 for 55 videos, 2 for 63 videos, and 3 for only 1 video. When the video source groups were compared, the difference was statistically significant (p = 0.01). The difference between academic and patient groups (p = 0.007); the dentist and patient groups were statistically significant (p = 0.02).ConclusionYouTube platform does not contain videos of appropriate quality to support the education of dentistry students in pediatric dentistry in Turkish.
Is mobile phone influence the status of pilot or the flight safety?
Authors: Zhu Shouxi , Gu Hongbin 
Published: March 2023

Background
This study aimed to explore the adverse influences of mobile phone usage on pilots’ status, so as to improve flight safety.

Methods
A questionnaire was designed, and a cluster random sampling method was adopted. Pilots of Shandong Airlines were investigated on the use of mobile phones. The data was analyzed by frequency statistics, linear regression and other statistical methods.

Results
A total of 340 questionnaires were distributed and 317 were returned, 315 of which were valid. The results showed that 239 pilots (75.87%) used mobile phones as the main means of entertainment in their leisure time. There was a significant negative correlation between age of pilots and playing mobile games (p<0.01). There was a significant positive correlation between the length of phone usage on rest days and the length of phone usage before sleep and the 15 items of the scale (p<0.01), age, flight hours and position had a significant negative influence on the total score of the scale (p<0.01), while the length of mobile phone usage on rest days and before sleep had a significant positive influence on the total score of the scale (p<0.01). Among the above five independent variables, the length of time spent using mobile phones on rest days is the most influential factor on pilot status.

Conclusions
Excessive use of mobile phones is very common among pilots, and it has become one of the key factors affecting the status of pilots. In any case, the longer the pilots use mobile phones, the greater the adverse impacts on their own status. At the same time, the longer pilots use mobile phones, the greater threat to flight safety.
Les retraits féminins du marché du travail : un fait social invisibilisé par la catégorie statistique de l’inactivité professionnelle
Authors: Beaufils Constance 
Published: March 2023

RésuméLes femmes durablement retirées du marché du travail, souvent appelées « femmes au foyer », sont peu étudiées dans le champ académique français. Cette invisibilité n’est pas sans enjeux. Elle entrave la compréhension de la stratification sociale, et perpétue des rapports sociaux de genre en niant la valeur du travail domestique. À partir des données longitudinales rétrospectives (enquête SIP 2006-1010), cet article dresse un bilan statistique des situations d’inactivité professionnelle déclarées par les hommes et les femmes et questionne ce manque d’intérêt. Nous montrons que les périodes d’inactivité professionnelle liées aux configurations familiales continuent de marquer une majorité de parcours de vie féminins, et peuvent être analysées comme un fait social. La catégorie statistique de l’inactivité professionnelle produit en partie leur invisibilité, car en plus de rendre difficile leur objectivation, elle les regroupe avec des situations aux caractéristiques très distinctes, notamment masculines.
AbstractWomen who are permanently withdrawn from the labour market, often called “housewives”, are little studied in the French academic field. This invisibility is not without its challenges. It hinders the understanding of social stratification and perpetuates gender relations by denying the value of domestic work. Using retrospective longitudinal data (SIP surveys 2006-1010), this article draws up a statisticalassessment of the situations of professional inactivity declared by men and women and questions this lack of interest. We show that periods of professional inactivity linked to family configurations continue to mark a majority of women’s life paths, and can be analysed as a social fact. The statistical category of professional inactivity partly produces their invisibility, because in addition to making it difficult to objectify them, it groups them together with situations with very distinct characteristics, particularly for men.

Published: March 2023

Abstract
Zn–Al–Mg coating galvanized steel in resistance spot welded (RSW) in different configurations of DC51D was investigated to illustrate the nugget evolution process and mechanical properties of the joints. Results show that the microstructure of welded joints can be divided into nugget zone (FZ), heat-affected zone (HAZ), and base metal zone (BM). FZ was composed of lath martensite. The average hardness value of the weld joint was 110 HV0.2 while the FZ was up to 300 HV0.2 due to the formation of lath martensite. The failure modes can be divided into interface fracture (IF) and pull-out fracture occurred (PF) under different welding parameters, in which shear dimples showed had a typical plastic fracture morphology. The best range for welding parameters was found to be 12–18 cycles in which the nugget diameter reached 5.5 mm. The process of nugget evolution in HAZ and FZ was discussed.

Authors: Dinušová Dominika 
Published: March 2023

Abstract
The study focuses on the conceptual development of Latin American revolutionary thought, capturing the trajectory in the formulation of revolutionary ideals along the evolutionary axis from independence to socialism. The aim of the study is to grasp and explain the evolution of revolutionary ideals in order to demonstrate the broader context of current social processes in Latin America through a historical-philosophical analysis of the ideological basis of social movements in the region. An analysis of the ideological contexts captured in the continuity of historical development, which affected the shaping and nature of the current transformation processes, may facilitate our understanding of the broader context of the articulated need for social change in the Latin American setting as well as of the current societal challenges pertinent to social change and innovation on a global scale.

Published: March 2023

Abstract
In recent years, meta-analysis has evolved to a critically important field of Statistics, and has significant applications in Medicine and Health Sciences. In this work we briefly present existing methodologies to conduct meta-analysis along with any discussion and recent developments accompanying them. Undoubtedly, studies brought together in a systematic review will differ in one way or another. This yields a considerable amount of variability, any kind of which may be termed heterogeneity. To this end, reports of meta-analyses commonly present a statistical test of heterogeneity when attempting to establish whether the included studies are indeed similar in terms of the reported output or not. We intend to provide an overview of the topic, discuss the potential sources of heterogeneity commonly met in the literature and provide useful guidelines on how to address this issue and to detect heterogeneity. Moreover, we review the recent developments in the Bayesian approach along with the various graphical tools and statistical software that are currently available to the analyst. In addition, we discuss sensitivity analysis issues and other approaches of understanding the causes of heterogeneity. Finally, we explore heterogeneity in meta-analysis for time to event data in a nutshell, pointing out its unique characteristics.

Relative amplitude frequency plot for a cantilever beam, a double clamped beam (DCB), a cantilever beam with end mass, normal vibration of a clamped beam mass, a double clamped beam with axial force, normal vibration of a clamped beam mass are demonstrated by using MEMSolver simulation version 3.3. The frequency shift for DCB with axial force is clarified. The lowest modal frequencies of a square and round diaphragm are also reported. The lowest modal frequency of a bent beam suspension is simulated also. The dependence of mid-section of the folded beam on the resonance frequency and on the short leg of the serpentine beam are clarified. The displacement plot for a structure under free vibration with damping, the displacement plot for vibration under a step force with damping, amplitude frequency plot for vibration under harmonic force with damping and amplitude frequency plot for the vibration driven by the base excitation are also outlined in this work.

Authors: Kapoor Mamta , Joshi Varun 
Published: March 2023

Abstract

Via UAH tension B-spline DQM in the present research, numerical approximation of coupled Schrödinger equations in one and two dimensions is fetched. In the present research, a novel regime is generated as a fusion of a UAH tension B-spline of fourth-order and DQM to fetch the requisite weighting coefficients. To ensure the adaptability and effectiveness of the proposed regime, different numerical examples are elaborated. Present results are matched with previous results, and the elastic property is also validated for solitons. The fetched ordinary differential equations system is handled via the SSP-RK43 regime. The stability of the present method is verified via the matrix method. The robustness of the proposed regime is affirmed via error norms. The fetched results are acceptable and validated. Elasticity property via wave interaction is also covered in the present research. The present study also focuses on one very important property of physics, like elasticity, which is rarely discussed in the literature. The developed numerical regime will undoubtedly be useful in addressing various fractional partial differential equations of complex nature as well.
Assessment of paperboard large deformation at fold using digital image correlation technique

Published: March 2023

Abstract
For coated paperboard with large deformations, there is limited knowledge on the mechanisms that lead to coating damage and on the key properties that affect damage. Large deformations produce complex non-linear mechanical responses which often result in significant internal damage. The objective of this work was to establish methods to directly measure local deformation at a fold using a stereo digital image correlation (DIC) technique and a folding device designed in-house. This allowed monitoring of deformation from both cross-section and surface views, from which curvature and strain could be analyzed. This approach allowed observation and quantification of the initiation and propagation of damage. Testing showed that elastic estimation of deformation is valid only at very small curvatures but is still qualitatively useful. It was found that CD fold line shows a lower strain than MD fold line at a given curvature, but it ultimately reaches a higher level of surface strain. Additionally, localized maximum surface strain was shown to correlate better with surface damage at fold than the average surface strain. Furthermore, the introduced discontinuity index can provide a useful tool to compare surface damage at fold even for paperboard samples with different thicknesses.

Abstract
In this study, the effect of different concentrations of calcium hydroxide (Ca(OH)2) was evaluated as a pre-treatment for accelerated carbonation and its influence on the fibrillation of cellulosic pulps to obtain nanofibrils, and its application as a coating agent for papers. Eucalyptus (EUC) and Pine (PIN) unbleached cellulosic fibers were submitted to pre-treatment with Ca(OH)2 at concentrations of 5 and 10% and subjected to accelerated carbonation, being subsequently mechanically fibrillated to produce cellulose nanofibrils (CNF). Pretreatment with calcium hydroxide followed by accelerated carbonation provided a 35% reduction in energy consumption. Cellulosic pulps EUC and PIN pretreated with calcium hydroxide showed higher fibrillation efficiency. There was a reduction in the cobb test values for papers coated with CNF in PIN. The WVP was lower for papers coated with CNF of EUC and control PIN. The CNF coating of EUC and PIN provided an oil barrier for the kit 11 solution. The CNF coating improved the dispersion of PVA and PVOH. The papers coated in this work have the potential to be used as packaging for fatty and oily foods or as a spreading agent for other industrial coatings.
