Politique d’Éloge des bâtards
Authors: Saint-Amand Denis
Published: December 2022

Roman de la résistance, Éloge des bâtards se fonde sur l’entrelacement des récits de soi transmis par les membres d’un groupuscule activiste et d’une série d’actions réalisées, discutées ou projetées par ces derniers. Le présent article interroge les ambivalences de cette figuration, en se penchant sur les rouages, effets et valeurs des représentations du groupe et des modes d’agir collectif qu’il développe, et en les confrontant à la fois aux textes antérieurs d’Olivia Rosenthal et à d’autres fictions contemporaines de la révolte (chez Nathalie Quintane ou Sandra Lucbert, notamment) pour tenter de saisir ses logiques et ses enjeux politiques.
« Ni trop loin ni trop près : la distance dont j’ai besoin pour écrire ». Une conversation avec Olivia Rosenthal
Authors: Kieffer Morgane
Published: December 2022

Ce dialogue s’inscrit dans la continuité d’une collaboration d’un an avec Olivia Rosenthal, organisée à l’occasion de la préparation de ce numéro de Relief autour d’une journée de travail auprès des étudiant·es de Licence de l'UJM (Université de Saint-Étienne) et d’une rencontre publique en librairie (Forum, Saint-Étienne, 16-17 mars 2022). La conversation qui suit a été menée à l’écrit et à distance. Il s’agit d’abord d’une lecture du dernier roman en date d’Olivia Rosenthal, Un singe à ma fenêtre (Verticales, août 2022), à partir de la tonalité crépusculaire de l’enquête qu’y mène la narratrice sur les attentats au gaz sarin à Tōkyō en 1995. Ce travail réveille des traumatismes et des culpabilités enfouis chez celle-ci comme chez les témoins qu’elle interroge. À l’historique se mêle alors l’intime, et il n’y a pas jusqu’à la liste des attentats envisagés qui ne dessine une cartographie personnelle du deuil et de la perte. Il s’est donc agi de réfléchir à la fois à la singularité de ce livre et, à partir de celui-ci, aux prolongements et aux infléchissements de la trajectoire rosenthalienne. Comment les grandes problématiques de l’œuvre s’affirment-elles jusqu’à ce dernier livre paru, comment s’infléchissent-elles aussi dans le temps long d’un parcours de vingt-trois ans d’écriture et de création ? Il faut lire là un point d’étape bien plutôt qu’un bilan ; l’occasion d’entretenir et de relancer la réflexion autour de points qui se confirment désormais comme repères cardinaux du travail de l’autrice.
Merci à Olivia Rosenthal de s’être prêtée à l’exercice.
‘Green’ Malthus? A Bibliographical Itinerary between neo-Malthusianism and Environmentalism
Authors: Bonasera Jacopo
Published: December 2022

This contribution presents a bibliographical itinerary on Twentieth century environmental revival of Malthusian doctrines. After introducing both the main conceptual strains inherent to the topic, and their scientific interest the essay takes into consideration the Post-WWII emergence of global environmentalism. A survey of the texts of 1960s and 1970s exponents of Neo-Malthusian environmentalism shows the important role played by this tradition of thought in shaping environmental concerns on both the scientific and the governmental level. The itinerary ends with an analysis of the main authors and strains of enquiry that have assessed the historical and conceptual relevance of Neo-Malthusian environmentalism. It is argued that more researches into Malthus’ legacy over time could grant significant theoretical gains both for the history of political thought, and its entanglments with the history of environmentalism.
Sacrificio del desiderio e matrimonio cristiano fra tardomedioevo e prima età moderna
Authors: Alfieri Fernanda
Published: December 2022

The essay examines the positions of Catholic doctrine in the early modern age on the connection between sacrifice and sexuality. It was examined a body of moral literature characterised by different levels of specialisation and relative recipients: manuals of spiritual instruction aimed at educated readers but not necessarily members of the clergy, texts for confessors and judges settling matrimonial disputes, works of wide circulation and others that remained in the shadows. A common line emerges: the sacrificial condition is desirable and necessary, and the conjugal status is hopelessly second to that, far more noble, far more sacrificial, of the religious devoted to celibacy.
Hand Hygiene Compliance Among the Public and in Ontario Hospitals
Authors: DeKraker Corina , Taboun Zahra Salem
Published: December 2022

Hand hygiene (HH) is a simple but important procedure for reducing the spread of infectious diseases, including gastrointestinal illness like cholera as well as respiratory illnesses like influenza and SARS-CoV-2, the virus responsible for the COVID-19 pandemic. In this article, we explore HH habits among the general public and among health care providers at Ontario hospitals and find that in both settings, HH compliance is sub-optimal. Overall, it is vital that we improve access to HH and stress good HH behaviours where access is not a concern to reduce the spread of various disease-causing agents.
Evolución de los frames sobre ataques yihadistas en España y Reino Unido (2004/5-2017)
Authors: Mukhortikova Tatiana , Palau-Sampio Dolors
Published: December 2022

Este artículo compara la cobertura, desde la perspectiva metodológica del framing, de cuatro atentados terroristas en España (2004, 2017) y Reino Unido (2005, 2017), con más de una década entre ellos, en dos periódicos de prestigio, El País y The Guardian. Los resultados del análisis de las 517 informaciones publicadas muestran una evolución sustancial en los encuadres o frames presentes en estos ataques yihadistas, al pasar de centrarse en las víctimas y la destrucción en 2004 y 2005 a priorizar la gestión y persecución del terrorismo en 2017. El énfasis se sitúa en revelar la estrategia y el modus operandi de los terroristas en lugar del caos resultante de sus acciones. En paralelo, la crítica a los errores en la lucha antiterrorista adquiere un peso relevante.
Framing en franja electoral en constituyentes electos para la redacción de la nueva constitución chilena
Authors: Quintano-Méndez Felipe , Denegri-Coria Marianela , Silva-Layera Francisca , Riquelme-Segura Leonor
Published: December 2022

Desde el año 1980, Chile mantiene una carta magna establecida en un período de dictadura sostenido por 17 años. En el año 2020, por medio de un plebiscito que tuvo como resultado la aprobación de un cambio constitucional, se concreta el proceso hacia una nueva constitución. Para dicho cambio, se requirió de la elección de personas civiles seleccionados por la ciudadanía, por lo que se realizó una campaña transmitida por televisión abierta denominada franja electoral. El análisis de esta franja, a partir de las teorías de framing, constituyó el objeto de estudio de esta investigación. Se llevó a cabo un levantamiento de información que conformó el corpus, a partir del cual se describieron los marcos de sentido (frames) dominantes en el contenido. Los hallazgos obtenidos permitieron dilucidar las temáticas de interés de cada conglomerado y que debiesen estar presentes en los debates en torno a la redacción de la nueva carta magna.
Representación de la cultura a través de la prensa local: los casos de Sevilla y Porto Alegre (2013-2018)
Authors: De Oliveira Julieti-Sussi , Figuereo-Benítez Juan C. , Moreno-Espinosa Pastora , Mancinas-Chávez Rosalba
Published: December 2022

El periodismo cultural difunde, fomenta, recrea y documenta la producción simbólica. Pastoriza (2006) lo define como una forma de cultura que ayuda a definir, dar voz o excluir relatos y sujetos que forman la cultura de una época. Este estudio aborda la construcción de la cultura en la labor periodística cotidiana. Para ello, parte de una investigación comparada sobre el peso de la representación de la cultura en medios locales en Sevilla (España) y Porto Alegre (Brasil). La metodología utilizada es el análisis de contenido, aplicado a 3.709 piezas publicadas entre 2013 y 2018 en la sección de cultura de los periódicos españoles Diario de Sevilla y ABC de Sevilla y brasileños Zero Hora y Correio do Povo. Se concluye que este periodismo tiene poca autonomía frente a la lógica económica de las industrias culturales, pues comparten la representación de una cultura comercial, en detrimento de la identidad local.
Ética y uso periodístico de la inteligencia artificial. Los medios públicos y las plataformas de verificación como precursores de la rendición de cuentas en España
Authors: Sanahuja Sanahuja Rosana , López Rabadán Pablo
Published: December 2022

La aplicación de la inteligencia artificial (IA) en el periodismo es una tendencia en desarrollo que afecta significativamente al modelo de producción y difusión periodístico. Como consecuencia, el uso de esta tecnología plantea diferentes retos éticos. En este contexto, la transparencia se sitúa como un principio clave para avanzar hacia un uso responsable de la IA por parte de los medios. El presente estudio analiza las webs corporativas y los blogs editoriales, principales espacios de rendición de cuentas, de nueve medios españoles vinculados a tres modelos profesionales diferentes: medios digitales, plataformas de verificación y entes públicos de radiotelevisión. Los resultados evidencian que ciertos medios públicos como RTVE están siendo precursores en la explicabilidad de su relación con la IA. Y por otra parte, el compromiso de las plataformas de verificación con la descripción de su metodología profesional favorece la transparencia sobre el uso que hacen de datos, algoritmos y automatizaciones.

Optical cathodoluminescence petrography, combined with SEM and LA-ICP-MS analyses: a case study from the Elatsite porphyry Cu-Au deposit
Authors: Stefanova Elitsa , Kadiyski Milen , Georgiev Stoyan , Hikov Atanas , Georgieva Sylvina , Peytcheva Irena
Published: December 2022

In the present research, we have applied a combination of Cold-CL petrography with two in-situ techniques (SEM-EDS and LA-ICP-MS) to study quartz-pyrite-sericite veins with some carbonates from the Elatsite porphyry Cu-Au deposit. Based on Cold-CL images, we found out that these veins are formed during two stages: quartz-pyrite with sericite and later quartz-carbonate with chlorite. Together with the quartz and carbonates small amount of arsenian pyrite, hematite, chalcopyrite, sphalerite, galena and apatite are precipitated. SEM-EDS and LA-ICP-MS allowed determining that the observed zoning of the pyrite from Q-Py stage is due to a variable Co and Ni content. Similarly, the zonal growth of calcite is due to variable Mn content. Pyrite and arsenian pyrite have different trace element composition. Arsenian pyrite has elevated Au, Ag, Cu, Pb, Sb and Tl contents compared to the pyrite. The combination of the three techniques was essential for resolving temporal relationships between the minerals within quartz-pyrite-carbonate veins and changes of the composition of the pyrite from the quartz-pyrite-sericite to the later quartz-carbonate stage.
New field and petrographic data about igneous rocks from Barnard Point, Livingston Island, Antarctica
Authors: Velev Stefan , Metodiev Stefan , Georgiev Neven
Published: December 2022

The Southeastern area of Livingston Island is built up by igneous rocks of the Eocene Barnard Point Pluton and related or younger dykes. Our new field and petrographic studies in the area show that the pluton consists of several main rock varieties namely gabbro, gabbrodiorite, granodiorite and granites, whose relationships evidences magma mixing processes. The internal parts of the former chamber contain levels enriched in mafic microgranular enclaves forming pronounced magmatic foliation, which towards western contact of the pluton transits to a subvertical N-S trending solid-state foliation and both parallelize the main foliation of the metamorphic host rocks. The latter evidences for a room creation and magma emplacement in tectonically active setting.
Geochemistry and depositional settings of Paleozoic cherts from Western Bulgaria: preliminary results
Authors: Boncheva Iliana , Andreeva Polina , Sachanski Valeri
Published: December 2022

Paleozoic (Silurian and Devonian) cherts from Western Bulgaria occur in three tectonic units: Svoge, Lyubash-Golo Bardo and Morava. The SiO2 content in these rocks varies from 76.06% to 96.02%. The silica source and depositional settings of the cherts have been interpreted based on the received geochemical major element data. The calculated Si/(Si+Fe+Al+Ca) ratio and Al–Fe–Mn diagram plotting at non-hydrothermal field suggest that most of silica in the cherts is biogenic or both biogenic and terrigenous in origin. On the other hand, all studied siliceous samples plot into the field of the continental margin sediment environments on the Fe2O3/TiO2 vs. Al2O3/(Al2O3+Fe2O3) diagram. The calculated MnO/TiO2 ratio also indicates deposition in continental shelf or slope environments.

Ore mineralogy and mineral chemistry of quartz-polymetallic veins in Caleta Argentina, Livingston Island, Antarctica
Authors: Sabeva Ralica
Published: December 2022

The quartz-polymetallic veins from Caleta Argentina, Livingston Island, Antarctica consist of pyrite, chalcopyrite, galena, and sphalerite. Chalcopyrite is the most common ore mineral and with concentrations of Ag (average 240.51 ppm). Sphalerite contains Ag (average 50.82) and Au (average 0.31 ppm), and pyrite – Au from not detectable to 1.03 ppm (average 0.59 ppm) and Ag from not detectable to 54.33 ppm (average 32.52 ppm). Caleta Argentina, as one of the ore occurrences in Hurd Peninsula, has to be correlated with the other research area such as the Bulgarian Antarctic Base, the Bulgarian Beach, and Sally Rocks.

The debris flows in the Lozenska Mountain from Subboreal and Subatlantic periods
Authors: Kenderova Rossitza , Kecheva Nadezhda
Published: December 2022

This research was conducted in June 2020 in connection with carrying out rescue archaeological excavations of a site recorded during the construction of the Sofia Ring Road, in the northern foothills of the Lozenska Mountain. On the basis of sedimentological studies of cultural layers, the flow of two mudflows with a southeast-northwest direction were proven at different depths. The discovered archaeological artefacts, mainly fragmented ceramic vessels, help to date these two flows through the Subboreal and the lower Sub-Atlantic. The first, located deeper than the modern surface flow, is dated after the 2nd millennium BC. (i.e., from the Subboreal). The second is the shallower stream, after the Roman era, II–IV centuries AD. (i.e., Sub-Atlantic). Both flowed into the Iskar River. Nowadays. it is difficult to determine their exact location. The archaeological sites from the two streams brought artifacts located in a south/southwest direction, closer to the northern slope of the Lozenska Mountain.
Micrometeorological measurements of air temperature in part of the northern slope of the Western Rhodopes (preliminary results)
Authors: Matev Simeon
Published: December 2022

The present study characterizes some microclimatic differences on the northern slope of the Western Rhodopes Mountains. The data for the analysis are based on the observations at three points: Brestovitsa at the foot, Bryanovshtitsa on the slope and Vurhovruh hut on the ridge, during July and August. Average temperatures, average minimum and maximum temperatures as well as the absolute minimum and maximum temperatures were established. They decrease naturally in accordance with altitude change, showing a dependence on synoptic conditions and microclimatic differences. The vertical temperature gradient is calculated for the studied parameters, with the largest values for the absolute maximum temperature amounting to 1.1 °C and the smallest for the absolute minimum and mean minimum temperature amounting to 0.5 °C. The largest values of the vertical temperature gradient for all parameters were observed between Brestovitsa and Bryanovstitsa.
Interpretation of CPTu and SPT data about sandy soils in the Plovdiv region
Authors: Angelov Lyubomir , Vasileva Tanya
Published: December 2022

CPTu (Piezocone Penetration Test) and Penetration tests – SPT (Standard Penetration Test) are the most used in situ tests in order to map a soil stratigraphy and determine the geotechnical parameters of construction soils. A comparison has been made between the relative density values obtained on the basis of the two types of field trials. The soils examined are classified according to well-established classification diagrams. The sandy soils are described in the range of dense to very dense. They have good strength and deformation characteristics – with a high friction angle and high Young’s modulus but the presence of a high level of groundwater is a prerequisite for their liquefaction under dynamic impacts.

Background: Road traffic accidents are a major non-communicable epidemic that accounts for death and morbidity in the world today. Despite considerable attention given to health statistics of road traffic accidents (RTAs), the pattern of bone fracture aspects of injuries resulting from RTAs is not fully understood in Saudi Arabia. This review aimed to study the epidemiological pattern of fractures due to RTAs in Saudi Arabia. Methods: This systematic review was based on the latest evidence of RTA fractures in the Kingdom of Saudi Arabia (SAUDI ARABIA). All articles published during the last 12 years on road traffic accident-associated fractures in SAUDI ARABIA were analyzed. We examined 12 studies published between 2012 and 2022. Eleven included studies were cross-sectional studies and collected data retrospectively, while one study was a cohort. Results: A total of 4709 patients with fractures admitted in 2010–2022, followed by road traffic accidents, were included. Male patients accounted for 81.6% (n = 3843) of all fractures reported. The most commonly fractured body areas were the upper limb extremities (30.05%), followed by lower limb extremities (11.30%), head or skull fracture (10.53%), spine fracture (8.83%), ribs fracture (8.52%), neck fracture (8.09%), pelvis fracture (3.44%), clavicle fracture (1.89%), and sternal fracture (0.28%). Among the upper limb fractures, the femur bone was most fractured (17.06%), and the combined tibia patella and fibula accounted for 17.69% of upper limb fractures. Conclusion: Lower limb fractures, especially femur bone fractures, are prevalent in Saudi Arabia, and caused by RTAs, especially among young males. Therefore, the concerned authorities need to employ and implement stricter traffic rules to minimize the risk of RTA fractures and their subsequent increased morbidity and mortality rates

Radiations are extensively used for diagnostic imaging and treatment. The primary health concern for healthcare facilities is radiation safety. Patients, physicians, and staff in numerous fields, including radiology, interventional cardiology, and surgery, are concerned about radiation safety due to their increased risk of occupational exposure. Occupational exposure is the outcome of radiation exposure at work. Radiation from diagnostic imaging modalities such as computed tomography, mammography, and nuclear imaging are a modest contributor to the healthcare workers' cumulative dose exposures. Any scattered radiation exposure can be dangerous for patients and medical personnel. In order to lessen the detrimental effects of ionizing radiation, radiation protection is critical to prevent unneeded radiation exposure. The purpose of this research is to review the available information about occupational exposure of scatter radiation and proper protective methods. Fluoroscopic imaging, which employs x-rays to produce dynamic and cinematic functional imaging, is the source of the majority of radiation exposure in medical settings. Healthcare workers are exposed to low doses of ionizing radiation during various diagnostic and therapeutic procedures. Chronic exposure to low doses of radiation can have many negative effects on human health, such as cataracts and, among the most serious an increased risk of certain types of cancer. The hazards of radiation exposure among healthcare workers are well-documented in literature. To lower radiation exposure, protective equipment is vital. A lead apron, thyroid shield, and lead glasses are essential parts of protective equipment. Implementation of the guidelines for safety and protection from radiation are needed.

Pericoronitis is the medical term for an oral inflammatory condition brought on by an infection of the soft tissues in proximity to the crown of an immature tooth, including gingiva and dental follicle. It is believed that microbial entry into the follicular area begins the infection once the tooth's follicle establishes contact with the oral cavity. Pericoronitis's microbiota primarily consists of anaerobes. It is commonly accepted that the build-up of food particles close to the opercula and the occlusal injuries caused by the opposing tooth to the tissues present pericoronally both accelerate this process. Third molars that are oriented vertically are more frequently affected by pericoronitis than those that are oriented horizontally, which had a lower incidence of the condition. Pericoronitis may be more likely to develop in patients with impaired immune systems, such as those with uncontrolled diabetes or immunodeficiency diseases. Patients with acute pericoronitis exhibit regional erythema, edema, purulence, and intense throbbing pain radiating to the ear, throat, floor of the mouth, temporomandibular joint, and posterior submandibular region during intraoral physical examination. Advanced cases including those developing into cellulitis, Ludwig's angina and peritonsillar abscesses may necessitate immediate attention including surgical intervention. It is advised to utilize only localized treatment measures for patients with localized pain and edema involving the pericoronal tissues and are free of local or systemic symptoms. Antimicrobial therapy is advised if the patient is displaying regional or systemic manifestations in as well as local pain and edema. Surgery is advised only when there have been two or more incidences of pericoronitis or other pathological conditions which maybe potentially be complicated by the presence of partially erupted tooth.

One of the most often diagnosed urological disorders is kidney stones with a prevalence which varies between 5% and 10% globally. In 1924, Crowell presented the first description of stone disintegration by direct irrigation. Since then, chemolysis-based dissolution therapy has been applied for the treatment of kidney stones in both primary and adjuvant settings, with different degrees of success. Depending on the type of stone, several chemolysis techniques can be applied. It has been suggested that d-penicillamine, tromethamine-E or tiopronin, and Nacetylcysteine can dissolve cystine stones. While phosphate stones are known to dissolve in acidic solutions. Renacidin and Suby G are two of the most common compounds used for chemolysis. Chemolysis can be utilized as a stand-alone therapy or as an adjuvant to shock wave lithotripsy, percutaneous nephrolithotomy, or open stone removal. The purpose of this research is to review the available information about overview of oral chemolysis types and its effectiveness in treating kidney stones. Oral chemolysis is a safe and effective treatment modality for patients with kidney stones. However, oral chemolysis is infrequently used despite the potential benefit of avoiding stone surgery with all its potential risks. The absence of trustworthy predictors of its outcome and the scarcity of high-quality data on its effectiveness are two factors contributing to its restricted utilization further clinical trialbased research is therefore needed to elaborately study the efficacy profile of oral chemolysis on various stone sizes and types.

Tobacco smoking is now increasing rapidly throughout the Arab countries and is one of the biggest threats to current and future world health. The negative effect of cigarette smoking on the quality of semen has been examined in numerous research. In Saudi Arabia, the overall number of couples consulting infertility clinics is on the rise. This systematic research aims to investigate the impact of smoking on the hormonal profile and semen parameters of Saudi Arabian male patients visiting infertility clinics. Online databases were searched for pertinent English publications that met the inclusion and exclusion criteria of this research (Cochrane library, PubMed, EMBASE, and Google Scholar respectively). Semen parameters (volume, count, motility concentration, pH, morphological and hormonal parameters), morphological abnormalities, and reproductive hormones were all evaluated as clinical endpoints. Finally, we looked at 6 studies that met the inclusion and exclusion standards of this study and were incorporated into the systematic review. The studies enrolled participants from 2004, including 1236 infertile male subjects, 41.54% smokers, and 58.45% non-smokers. Two included studies observed a significant reduction in semen volume, three studies observed a significant reduction in sperm motility, four included studies found a significant reduction in sperm count, and one study each reported a significant reduction in sperm abnormal forms and semen pH respectively in comparison to smoker and non-smoker infertile patients. Overall findings demonstrated a considerable negative impact of smoking on semen parameters. In conclusion, concerning the clinical endpoints that were studied in this analysis, tobacco smoking is found to be associated with a lower testosterone level, semen volume, sperm motility, sperm count and concentration, and an increase in the number of morphological defects or abnormal sperm forms in Saudi Arabian infertile men

The normal course of Chronic obstructive pulmonary disease (COPD) includes a progressive reduction in lung function, exacerbations that necessitate primary care intervention or hospital admission, a steady decline in quality of life, and a shorter life expectancy. COPD is one of the ambulatory or primary care-sensitive illnesses for which it is hypothesized that efficient primary care management will lower the probability of hospital admission. Long-acting beta-agonist and inhaler steroid combination therapy improves spirometric results and overall health while lowering the annual risk of COPD exacerbations. Use of two or more treatment modules based on models designed specifically for chronic care delivery in developed countries have proven successful in lowering hospitalizations as well. Access to other therapies, such as pulmonary rehabilitation, acute exacerbation evaluation programs, and community or hospital-based respiratory specialists, may also be important. The goal of interventions to lessen the prevalence of COPD in underserved areas has to focus on locally driven integrated solutions, such as media campaigns to raise awareness and persuade at-risk individuals to get tested, as well as training for primary care workers on the significance and advantages of earlier detection and effective operation of chronic obstructive pulmonary disease. Importantly, uptake of influenza vaccination has demonstrated a link with hospital admission rates at the practice level. Proposed solutions for lowering hospitalization and reducing exacerbations among patients with COPD include greater access to pulmonary rehabilitative care, more rigorous implementation of smoking cessation programs and availability of modern long-acting medications.
An Overview of Maryland Bridges and their Clinical Applications

Published: December 2022

Resin bonded bridges are fixed prostheses that require little to no surgery and are held in place by composite resin cements. The "Maryland" bridge, which was made possible by the invention of the electrolytical etching method for nickel-chrome alloys, enabled the resin cement to undergo micromechanical adhesion to the metal surface. Their major advantage is that they require minimal, or at best, no tooth preparation. The preparation is usually kept within enamel which eliminates the need for local anesthesia during tooth preparation. When care is taken to maintain the margins of the Maryland bridges supragingivally, periodontal health is preserved. An additional advantage of the Maryland bridges is that in the event that a wing debonds, it is possible to rebond it after merely cleansing the wing and tooth. The most frequent issues with resin-bonded prostheses including debonding are cavities and three-tooth discoloration. There are two alternatives if a bridge debonds: rebonding or remaking. Replacing the bridge has been proven to have a greater success rate. During the assessment phase, any deleterious behaviors should be discovered, and the individual should be advised to stop doing things like biting their nails or pens. They offer an alternative to traditional bridgework10 or implants for restoring lost teeth, and because they typically don't require local anesthesia, individuals who are afraid of needles or don't want to undergo extensive surgery can have the operation. Maryland bridges are a choice in situations where there might not be enough bone or three-dimensional space for implant implantation. Patients also prefer smaller sessions because of the cost savings compared to traditional bridgework and implant-supported restorations. These prostheses should be considered as a restorative choice for short time periods and those desiring minimal chair time given complete patient evaluation and the application of appropriate therapeutic procedures.

Obesity among children is a global public health concern. There is significant evidence that obese children experience social, psychological, and physical problems as a result of their weight. Worldwide prevalence rates of obesity have increased significantly among children and adolescents in both developed and developing countries. Compared to their peers who are a healthy weight, obese children are more likely to experience anxiety and depression, be bullied, experience discrimination, and express low self-esteem. Additionally, obesity and overweight have been associated with poor health outcomes and a decrease in quality of life. Compared to those of healthy weight in their youth, obese children and adolescents are more likely to become obese adults and have more serious disease risk factors. Therefore, it is recommended that physicians should screen children aged six and older for obesity, and for those confirmed to have body mass index in the overweight or obese categories, refer or give behavioural intervention as children may benefit from comprehensive behavioural interventions in terms of improvements in their weight status further enhancing their quality of life. Because of its ease, dependability, and established link to adult obesity, using age- and sex-adjusted body mass index percentiles is the suggested strategy for screening overweight and obesity in children. Awareness and practice of obesity screening among physicians and parents is also necessary. The purpose of this research is to review the available information about importance of obesity screening programs among children and its effect on their quality of life.

Background: Coronavirus infection disease 2019 (COVID-19) is a novel viral respiratory tract infection that caused a global pandemic. It can be associated with many complications including acute respiratory failure which can lead to intensive care unit (ICU) admission. This study evaluates the characteristic of patients with COVID-19 admitted for ICU care, and determine factors associated with poor outcome of care. Methodology: This is a retrospective review of patients admitted into the ICU of Buraidah Central Hospital on account of COVID-19 complications between March 2020 and October 2021. Records on patients` age, gender, body mass index (BMI), smoking habit, co-morbidities, ventilatory support type, the occurrence of pneumothorax, duration of ICU stay, and outcome of treatment of disease were extracted and analyzed for descriptive statistics, and the Chi-square test using SPSS version 28. Results: A total of 1035 patients were admitted into the ICU due to COVID-19 infection. The mean age of the patients was 59.95±21.10 years (range = 5-104 years). There were more males (N=695, 67.1%) than females (340, 32.9%). The majority of the patients (545; 52.7%) were elderly, followed by middle-aged adults (360; 34.8%); and were either overweight or obese (N= 849, 82%). More patients (568, 54.9%) were admitted in the year 2020, compared to the year 2021(467; 45.1%). Similarly, mortality rates were higher in the year 2020 (252, 44.4%) than in 2021 (219; 46.9%). There was a significant association between hospital course and patients who had higher BMI, endotracheal intubation, pneumothorax, emphysema, and co-morbidities such as hypertension and diabetes mellitus (p < .001). Also, there is a significant association between hospital course and the patient’s age, gender, and month of admission (p < .001). Also, there is a significant association between hospital course and the patient’s age, gender, and month of admission (p<.001). Conclusion: COVID-19 was an indication for ICU admission. Most patients were middle-aged or elderly and were predominantly male. Most admissions occurred during summer, and there has been a steady decline in admission rates and mortality. The male gender, obesity, and other co-morbidities are associated with worse outcomes.

For direct composite resin restorations, the "stamp technique" aids in achieving accurate occlusal topography. Stamp is an index that mimics the structure of a natural tooth. The cavity is produced after stamp manufacture on an unprepared occlusal surface, and the resulting stamp is then applied to the last composite increment prior to final curing to create a precise duplicate of the pre-operative structure. For patients desiring pre-treatment occlusal anatomy even for posterior teeth, the aesthetic restoration has become standard practice in modern dentistry and offers an appropriate reference for replicating both aesthetic and proper function. In Class I and Class II preparations, where the occlusal surface is undisturbed prior to treatment, the stamp approach is recommended. Light-cure composites, self-cure acrylate resin, polyvinylsiloxane bite registration material, liquid dam material, clear silicon mould, and occlusal transfer devices are some of the materials utilized to make the occlusal mimics. The stamp technique is a quick process that requires less chairside time for polishing and finishing as well as for rebuilding the occlusal morphology. Because the matrix duplicates the occlusal architecture, contouring the restoration does not involve manual labor, specialized tools, or excessive amounts of material. Severely carious teeth cannot be rebuilt with this method, and examination prior to restoration is necessary to guarantee appropriate occlusion.

It is the responsibility of orthodontists to diagnose periodontal issues and address the multidisciplinary therapy of various periodontal issues needing orthodontic therapy. Adults can be quickly and effectively screened for periodontal disorders using the periodontal screening and recording technique. It condenses the information into the basic essential paperwork. An orthopantomograph which is useful for basic scanning, is used by most orthodontists. Plaque, subgingival calculus, and occlusal trauma are some of the etiologic variables that are the focus of preorthodontic periodontal therapy. A customized home-care program is part of the initial phase of periodontal treatment. Before beginning orthodontic therapy, the periodontist should assess sites of minimally attached gingiva. Grafting may be necessary for teeth with gingiva less than 2 mm thick. The conventional techniques for root covering were gingival and pedicle grafting. The type of defect, such as a crater, hemiseptal defect, three-walled defect, and/or furcation lesion, will determine the amount of the osseous repair. The bone level may have moved back several millimeters from the cementoenamel junction in a patient who has experienced extensive horizontal bone loss. To correct the disparities, periodontal surgery might be necessary. The patient must continue on a three-month periodontal maintenance program once orthodontic treatment is finished. After the release of the band, it may take up to six months for appropriate bone remodeling, the termination of mobility, and the constriction of the periodontal ligaments to occur.

The properties of elastomeric materials are strongly influenced by the inclusions resulting from the ingredients and the elaboration process. A methodology is proposed to differentiate the inclusions harmful for fatigue (larger than a few micrometers) in elastomers according to their chemical nature, and to characterize them quantitatively with sufficient statistics. Three techniques are used and compared: digital optical microscopy (OM), scanning electron microscopy (SEM) associated with energy dispersive X-ray spectroscopy, and X-ray micro-computed tomography (μ-CT). Six materials are used to challenge the methodology. In addition to the usual metal oxides and carbon black agglomerates, three atypical types of inclusions are highlighted, generating specific detection difficulties. A relevant image analysis procedure is developed to automatically detect the inclusions from the acquired images, more objectively and accurately than with the classical thresholding methods. The morphology and the spatial distribution of the different inclusions populations are then determined. μ-CT is the most comprehensive and accurate method for classification and statistical characterization of inclusions. Furthermore, relevant data on the size distribution of inclusions can be obtained using backscattered electrons (SEM-BSE) or digital OM. SEM-BSE provides more accurate results than digital OM.

This paper examines the effect of macroeconomics and supply chain finance (SCF) on the profitability of the manufacturing companies, specifically in Indonesia from 2017 to 2021. Furthermore, the study demonstrates the critical role of macroeconomics and SCF in profitability through the use of general moment method (GMM). The results indicate that cash conversion cycle (CCC) is detrimental to profitability (P), while macroeconomics has a positive impact on it. In addition, strong profitability is negatively and positively correlated with the leverage (LEV) and sustainable supply chain management (MRPB) control variables, respectively.

Published: December 2022

This research aims to account for the cost of quality through lean and agile operations strategies with empirical evidence from the Aviation industry in the UAE. The cost of quality improvement through lean and agile strategies was not researched enough in the aviation industry. This research will contribute with great knowledge in the aviation industry. The research design used a descriptive, explanatory, causal, and analytical method. A cluster sampling technique was used with a valid sample size of 251 respondents for analysis by multiple regression using ANOVA. Results indicated the significant relationship between lean and agile operations strategies on the cost of quality. There is a direct positive significant relationship between the cost of quality and SC strategies to get quality products cost-effectively. This research was limited to the lean and agile strategies and cost of quality analysis in the aviation industry in one city in the UAE. In contrast, it requires detailed research to explore other cities and assess the aviation industry's challenges while implementing lean and agile strategies. Cost elimination with high-quality production is fundamental for a successful business; lean and agile operations can reduce airline companies' costs and propose the criteria to adopt the strategic implementation efficiently.
