Die Pensenreduktion als Aushandlungsort „guter“ Elternschaft
Authors: Glaser Iris
Published: November 2024

Der Artikel befasst sich mit der Aushandlung von Unterrichtspensen zwischen schulischen Akteur*innen und Eltern auf der Schuleingangsstufe in der Schweiz. In der Mehrzahl der Schweizer Kantone wurde in den letzten Jahren das Schuleintrittsalter vorverlegt. Im Zuge der früheren Einschulung von Schüler*innen wurden die reduzierten Unterrichtspensen im ersten obligatorischen Schuljahr in der schweizerischen Bildungslandschaft zunehmend bedeutsam. Diese Thematik wird in der vorliegenden Untersuchung aus einer subjektivierungsanalytischen Perspektive untersucht. Dabei werden zwei zentrale Aspekte aufgezeigt: Erstens wird dargestellt, inwiefern sich über neue Mitsprachemöglichkeiten von Eltern bei Unterrichtspensen Prozesse der Responsibilisierung (Jergus 2018) für Familien manifestieren. Zweitens wird anhand von zwei kontrastierenden Fallbeispielen herausgearbeitet, inwiefern sich diese Prozesse der Responsibilisierung im Kontext von Ungleichheitsverhältnissen für Familien unterschiedlich manifestieren.
Die Herstellung von (In-)Kompetenz: Doing difference, Reproduktion und Subversion in schulischen Leistungsordnungen
Authors: Grimmer Bettina
Published: November 2024

Der Beitrag zeigt auf Grundlage ethnographischer Daten aus dem Unterricht in einer Schweizer Sekundarschule, wie die Leistungsordnung einer Klasse Zug um Zug hergestellt wird. Bei einem Wettbewerb in einer Lektion im Technischen Gestalten werden die Produkte der Schüler*innen als Materialisierung individueller Kompetenz in einen geordneten Handlungszusammenhang gestellt und in Relation zueinander gesetzt. Ich diskutiere, wie Schüler*innen in das schulische doing difference involviert sind, aber auch, unter welchen Bedingungen subversive Praktiken die Leistungsordnung in Frage stellen können. Es wird deutlich, wie sehr Leistungsordnung und Interaktionsordnung verbunden sind und wie stark situative Zwänge auf die Herstellung von (In-)Kompetenz wirken, die letztendlich soziale Ungleichheiten reproduziert.

Detailed experimental procedures are given to allow for ease of synthesis.
Vibronic Coupling Effects in the Photoelectron Spectrum of Ozone: A Coupled-Cluster Approach
Authors: Wójcik Paweł , Reisler Hanna , Szalay Péter , Krylov Anna , Stanton John
Published: November 2024

One of the most important areas of application for equation-of-motion coupled cluster (EOM-CC) theory is the prediction, simulation, and analysis of various types of electronic spectra. In this work, the EOM-CC method for ionized states, known as EOM-IP-CC, is applied to the closely lying and coupled pair of states of the ozone cation — X̃ 2 A1 and Ã2 B2 — using highly accurate treatments including up to the full single, double, triple, and quadruple excitations (EOM-IP-CCSDTQ). Combined with a venerable and powerful method for calculating vibronic spectra from the Hamiltonian produced by EOM-IP-CC calculations, the simulations yield a spectrum that is in good agreement with the photoelectron spectrum of ozone. Importantly, the calculations suggest that the adiabatic gap separating these two electronic states is somewhat smaller than currently thought; an assignment of the simulated spectrum together with the more precise band positions of the experimental measurements suggests T00 =1,368±65 cm−1 .

Published: November 2024

Artificial biomolecular nanotubes are a promising approach to build materials mimicking the capacity of the cellular cytoskeleton to grow and self-organize dynamically. Nucleic acid nanotechnology has demonstrated a variety of self-assembling nanotubes with programmable, robust features, and morphological similarities to actual cytoskeleton components. However their production typically requires thermal annealing that is not only incompatible with physiological conditions but also hinders the possibility for continuous growth and dynamic self-organization. Here we report DNA nanotubes that self-assemble from a simple mixture of five short DNA strands at constant room temperature, with remarkable capability to sustainably grow over prolonged time. The assembly, done in a monovalent salt buffer (here, 100 mM NaCl), ensures that the nanoscale features of the nanotubes are preserved under these isothermal conditions, enabling continuous growth up to 20 days and the formation of individual nanotubes with near flawless arrangement, a diameter of 22 ± 4 nm, and length of several tens of micrometers. We demonstrate the crucial role of the monovalent cation to achieve such properties. We finally encapsulate the strands in micro-sized compartments, such as water-in-oil microdroplets and giant unilamellar vesicles serving as simple cell models. Notably, nanotubes not only isothermally grow in these conditions, but also self-organize into dynamic higher-order structures, such as rings and dynamic networks, demonstrating that cytoskeleton-like properties can emerge from a combination of sustained growth and confinement. Our study suggests a method for engineering biomolecular scaffolds and materials that display sustained dynamic and life-like properties.
Are Grignard Reactions in Deep Eutectic Solvents Interface-Driven?

Published: November 2024

Organolithium and organomagnesium addition reactions to ketones are important and versatile procedures used in many sectors of synthetic organic chemistry. However, due to the high reactivity of these species, the reactions are normally done under an inert atmosphere at low temperature to control their selectivity. This imposes severe limitations for scaling up. Recent work has demonstrated the possibility to carry out these procedures safely on the benchtop, in air at room temperature using deep eutectic solvents (DES) to dissolve the substrate. Surprisingly the organometallic reagent is compatible with these unconventional conditions, and instead of undergoing fast decomposition in the DES, better yields and selectivities are observed than when working under standard conditions. Earlier it was posited that the choline chloride component of the DES might chemically activate the ketone substrate making it more amenable to reaction. Here we probe this hypothesis and suggest instead that the role of the choline chloride is to reduce the solubility of the substrate, forcing it to accumulate at the air-solvent (or organic solvent/DES) interface. Computational studies for the organometallic species in a DES/ether bi-phase system, also indicate a preference to localize at the interface. These factors suggest that surface accumulation promotes the addition reaction and account for these remarkable experimental conditions.
A review of methane emissions source types, characteristics, rates, and mitigation across U.S. and Canadian cities
Authors: Vollrath Coleman , Xing Zhenyu , Hugenholtz Chris , Barchyn Thomas , Winter Jennifer
Published: November 2024

Cities are major aggregate sources of methane (CH₄) emissions and play a critical role in mitigating near-term global temperature rise. However, characterizing urban CH₄ emissions remains challenging due to the diversity and spatial distribution of sources. Furthermore, limited synthesis and integration of the literature has led to a poor understanding of the characteristics and contributions of different sources, with implications for policies and mitigation. This review consolidates findings from 103 peer-reviewed articles on CH₄ emissions from cities in the U.S. and Canada, highlighting key research priorities. We find that top-down (TD) estimates of total city-level CH₄ emissions exceed bottom-up (BU) inventory estimates by a factor of 0.7 to 4.9 in 34 studies. In city-level studies that disambiguated emissions by source, natural gas distribution and use, and landfills, dominated urban CH₄ footprints. The mean natural gas loss rate in cities of 1.8% ± 0.9% suggests a broader natural gas supply chain loss rate of 4.0% ± 0.9%. Notably, TD estimates of CH₄ emissions from six select U.S. landfills were, on average, 2.6 (± 1.8) times greater than self-reported estimates, suggesting that preferred calculation methods for reporting may systematically underestimate emissions and miss fugitive point sources. A limited number of studies examined mitigation but indicate that measurement is essential to identify mitigation opportunities and verify reductions. We raise questions and highlight challenges around existing BU inventories, urban natural gas loss rates, combustion slip, landfill emissions estimation techniques, and mitigation effectiveness. We conclude with recommendations on research priorities to address key knowledge gaps: (i) new source-level measurement datasets and modeling approaches for BU emissions estimation; (ii) more granular investigations to understand the specific sources and causes of CH4 emissions from urban natural gas infrastructure and end use; (iii) a better coupling between measurement and modeling of landfill CH4 emissions; (iv) mitigation-focused studies.
Biophysical System for the Detection and Quantification of Changes in Oligomeric States of STING at Attomolar Concentrations

Published: November 2024

Few protocols exist today that demonstrate repeatable resolution of small molecule interactions with target proteins at extremely low analyte levels, particularly at sub-femtomolar levels. We have developed two approaches for rapid screening and biophysical analysis which leverage changes in protein oligomer states to study highly potent small molecules. The first protocol employs microscale thermophoresis (MST) to measure competitive disruption of oligomerization following exposure of the target protein to its endogenous ligand. The second protocol engages dynamic light scattering (DLS) to measure the changes in physical size of oligomers after exposure to the endogenous ligand and/or analyte. STING (stimulator of interferon genes) is a protein that relies on oligomerization after ligand binding for intracellular signal transduction. Here we demonstrate the utilization of these methods through measurements of wild type STING oligomerization following exposure to 2’,3’-cGAMP and the compound clonixeril along with several analogs. Using these techniques, one can now measure small molecule inhibitor concentrations in the attomolar range when the target protein undergoes oligomerization as part of its natural biological activity.

Published: November 2024

Hydrogen sulfide (H2S) can be extremely flammable and hazardous. It is frequently found in industrial settings where individuals face serious dangers to human health and safety, such as in the production of oil and gas, wastewater treatment, and chemical manufacture. H2S can create serious health risks, even at low quantities, such as respiratory failure and fatalities, which makes gas detection imperative. In this study, ML models have been employed to predict how n-type materials doped with various metals—such as Ag, Pd, and Au—will react when they are exposed to hydrogen sulfide (H2S) gas. The tree-based machine learning models used in the study include Gradient Boosting Regression (GBR), Random Forest (RF), and Decision Tree (DT) coupled with several optimization strategies (such as Bayesian optimization, Random Search, and Grid Search). Additionally, the examination involves the utilization of Partial Dependence Plots (PDPs) and Shapley Additive exPlanations (SHAP) to gain insights into the intrinsic mechanisms of the ML model and to elucidate the opaque nature of the ML model, these post-model interpretations elucidate the significance of features in gas sensing.
Reversible and irreversible changes in protein secondary structure in the heat- and shear-induced texturization of native pea protein isolate
Authors: Nakagawa Hiroshi , Ubbink Job
Published: November 2024

The molecular mechanism of plant protein texturization under extrusion conditions was unraveled at the secondary structure level by decoupling the effects of heating, cooling and shearing on protein secondary structure. Native pea protein isolate hydrated at 50% w/w in H2O and in D2O, to allow detailed resolution of protein secondary structure, was subjected to temperature cycling in a temperature-controlled ATR-FTIR and was texturized at the gram scale by microcompounding. Upon heating without shearing, native α-helices and intramolecular-β-sheets unfold to random domains, followed by the formation of intermolecular β-sheets, inducing aggregation. During cooling, the intermolecular β-sheets become increasingly ordered, and random domains partially fold into non-native β-structures. Combined heating and shearing results in more extensive β-sheets than heating alone. The resulting β-rich structures provide for an entangled network of protein chains and a cohesive protein matrix. The effect of shear on protein association/dissociation is controlled by the specific mechanical energy (SME), with the degree of intermolecular -sheet formation increasing with increasing SME values up to ∼1000 kJ/kg, followed by a gradual decrease with further increases of the SME. The detailed molecular insights in the mechanism of plant protein texturization allows for a more controlled design of novel food products, including matrices for use in meat analogues.

Published: November 2024

Mechanical debridement is currently considered as the first line of defense against periodontitis. Often we need to add antibiotics to the armamentarium to treat this disease. Technological advancements are not very uncommon in many fields including dentistry. Our project was based on the comparison of efficacy of a new product Periowavetrade which is based on the principle of photodynamics with the standard treatment of periodontitis. Acomprehensive computer-based search combined the following databases into one search Pubmed Google Ovid and Cochrane. In addition hand searches were done for several journals not cataloged in the databases and the reference lists from published articles were checked. Since this is a fairly new device our database search turned no published studies and our focus turned towards the principle of photodynamic therapy PDT. We did a literature review again regarding PDT. All studies had to use some form of laser for treatment there had to be a pre-established diagnosis of periodontitis all studies had to be invivo and all studies had to be randomized controlled. We had a total of 1363 articles but after excluding the articles that did not meet the criteria we had four papers left.In conclusion there is a great need to develop an evidence-based approach for the use of lasers for the treatment of periodontitis. The literature review revealed that there is presently insufficient evidence to suggest that any specific wavelength of laser is superior to the traditional modalities of therapy

Published: November 2024

Objective To evaluate the effect of microwave sterilization on abrasion resistance of three commercially available acrylic resin denture teeth. Materials and Methods Thirty teeth from each brand of acrylic resin denture teeth selected were Premadent Acrypan and Truton. In each brand fifteen teeth were control and remaining fifteen were subjected to microwave sterilization. The ten human enamel specimens freshly extracted central incisors with crown portion embedded in acrylic resin were taken as abraders. The wear testing was performed using specialized custom made wear testing machine. The test specimens height was measured before and after wear testing by using digital vernier caliper. The difference in measurements noted before and after testing determines the abrasion resistance. All the results were evaluated and statically analyzed using T-test and ANOVA. Results The abrasion resistance of microwave sterilized acrylic teeth group has increased but shows no significant difference among each other but was found to be higher than the control groups. Conclusion Under the limitation of this invitro study the microwave sterilization can be considered as a useful method in not only removing microorganisms but also in improving the abrasion resistance of acrylic resin teeth.nbsp

DEPROFESSIONALIZATION: Anew approach to professionalization!
Authors: N Vanishree , V Chaithra. , Jacob Jeswin , Jain Hitendra
Published: November 2024

Technological advances in medicine have greatly enhanced the ability of physicians to treat disease and disability but at the same time changes in the organization and management of health care services are taking place. Challenging the prevailing model of professional dominance the concepts of deprofessionalization and proletarianization emphasize the effects of recent social and economic developments on the changing status of the medical profession and other related fields. There is evidence however that what the proponents of these concepts perceive as the professions response to external forces are in fact the unanticipated consequences of the professions campaign for autonomy. The challenge that faces medicine is a kind of re-organization that will change necessarily the profession as we know it today but this change will not affect the professional autonomy or any other of its essential characteristics but bring in more people from various other sectors into the medical field. This review article outlines the concept of deprofessionalisation professional autonomy and its types professional dominance rationalization of this approach the future and challenges of deprofessionalization.nbsp

Authors: Sharma Sheeba , Gupta Ankit , Sharma Hemant , Garg Deepti
Published: November 2024

The routine and frequent use of dental implants to replace missing teeth is accompanied by high expectations from patients. These expectations are not limited to function and esthetics but extends to patient comfort and time spent receiving treatment. The traditional two-stage implant protocol with delayed restoration has treatment duration of 1minus2 years in which patients have to wear a removable appliance and experienced significant discomfort during the recovery period. Nowadays immediate implant placement into an extraction site followed by immediate restoration of a dental implant can shorten the dental rehabilitation time and preserve patients esthetic appearance at all stages of treatment. This clinical report describes a simple and effective treatment option for replacing missing mandibular anterior teeth with implant supported fixed prosthesis using immediate loading protocol.nbsp

Fear Assessment in Pediatric Dental Practice using Facial Image Scale
Authors: R Hemalatha , C V Divyambika
Published: November 2024

Dental fear and its corresponding anxiety have been posing various problems in management strategies especially in pediatric age groups. The adverse effects of which are carried over into adulthood which in turn can lead to total avoidance of dental treatment and a deterioration in oral health consequetively.Formal assessment measures like projective techniques Facial Image Scale-FIS are essential to serve the purpose. Children project with a lot of subjective fears though they may vary in intensity from simple nervousness to dental anxiety. It evaluates dental fear in children from the point of view of dentists parents and children. Both dependant and independent variables were assessed using the same questionnaire. Therefore it is mandatory for a pediatric dentist to assess the levels of fear at an early stage so that they can identify those patients who need assistance on fear grounds thereby they could be alleviated or warded off to develop good patients for the future.The present study was one such attempt to record the fear status in children using the Facial Image Scale. The results revealed that children were more comfortable in the waiting area than in the dental operatory. Even within the confines of the operatory they were more comfortable with the less invasive procedures in comparison to the more invasive ones like extraction.We concluded the study with the notion that if we as dentists could dedicate some extra time towards conducting such surveys we could go a long way towards gaining a good rapport with our patients
Risk factors for Periodontal Disease – A Review
Authors: A. Patil Veena
Published: November 2024

Periodontal disease is one of the most common diseases in humans. It is multi-factorial in aetiology with microbial plaque as the principal initiator. It has been hypothesized that all cases of gingivitis need not progress to periodontitis and that progressive attachment loss occurs in case exposed to risk factors. Many factors have been identified to have specific role in modifying the disease progression. Knowledge of these risk factors is necessary to prevent and control periodontal disease in the population. The aim of this review paper is to explain some basic concepts related to the understanding of periodontal risk factors.

Authors: Muddugangadhar B.C. , GS Amarnath , Sangur Rajashekar , V. Rudraprasad I.
Published: November 2024

Though the concept of linear occlusion has been available since many years it has not been widely used to treat complete and partially edentulous patients. Literature has supported that the stability of mandibular denture can be considerably increased by use of linear non interceptive occlusal scheme by minimizing the horizontal force vectors that act to dislodge the prostheses. The article is therefore intended to provide an overview of the concept of linear occlusion and its role in enhancing mandibular denture stability.
Resin Ionomer Restoration: A Ray of Hope for Furcation Therapy – Case Report
Authors: Kudalkar Mithun , Shivanaikar Sachin , Nayak Aarati
Published: November 2024

Furcation invasion has long been a treatment dilemma for the clinician. Techniques advocated in the management of furcated posterior teeth ranges from conventional scaling and root planing SRP apically positioned flaps root amputations root resections tunnel procedures guided tissue regeneration and restorations. Long term success is predicated upon tooth retention and the arrest of further destruction within the furcation area. Hence this case report uses a resin ionomer restorative material in treatment of Class II furcation involvement of a maxillary molar. The results 9 months post operatively revealed a successful sealing of the furcation. This could be attributed to the role that the resin ionomer restorative material plays in obliterating the furcation defect and simplifying maintenance for the patient.

Published: November 2024

This study determined the effect of pH on the surface texture of commonly used posterior glass ionomer basedcontaining restorative materials. The materials evaluated included a compomer Dyract a giomer Beautifil II and two highly viscous glass ionomer cements Fuji IX and Ketac Molar. A resin composite Spectrum TPH was used for comparison. Thirty six specimens 5-mm diameter X 2-mm depth were made for each material. The specimens were divided into six groups and conditioned in the following solutions at 37degC for one week Citric acid pH 2 3 4 5 and 6 and distilled water pH 7. After conditioning the surface roughness Ra microm of each specimen was measured using a surface profilometer WYKO Surface Profilers Veeco Metrolog Group Arizona USA. Data was analysed using one-way ANOVA and Scheffes test at a significance level of 0.05. The effects of pH on the surface texture of glass-ionomer basedcontaining restoratives were material dependent. Ra values ranged from 0.03 microm to 0.85 microm and 0.06 microm to 4.90 microm for pH 7 and 2 respectively. With the exception of the composite the surface roughness of all materials evaluated was significantly affected by acids of low pH. The surface texture of highly viscous glass ionomer cements deteriorated significantly when conditioned in solutions of low pH which makes them more susceptible to clinical failure.

Published: November 2024

The process of rehabilitation in hereditary ectodermal dysplasia is challenging because it takes a long duration involving multiple prostheses. If the patient is very young and completely edentulous the clinical methods have to be stretched to unimaginable proportions. A case is reported where complete dentures had to be fabricated at an early age of 4 years. The most challenging task was the fabrication of a face bow. Teeth also had to be characterized to suit the child.
Effect of Fluoride Varnish on Demineralization Adjacent to Orthodontic Brackets: An In vitro Comparative Study
Authors: M Sagarkar Roshan , B Chandralekha , . Shasikala
Published: November 2024

The aim of this study was to compare in vitro the effect of fluoride varnish on inhibition of enamel demineralization adjacent to orthodontic brackets bonded with RMGI cement and Light cure composite resin. These bonding adhesives were used with and without fluoride varnish in four different combinations on 40 extracted premolars. The teeth were constantly circulated in artificial saliva solution for 11 hours and artificial caries-producing solution for 1 hour and the cycle was repeated twice a day for a period of 31 days. Longitudinal sections of tooth were made in bucco-lingual direction with the help of hard tissue microtome to yield sections that were 100mum thick and later examined under a polarized light microscope to examine the depth of the lesion. The maximum demineralization was seen in the occlusal zone and least demineralization was seen in the gingival zone for all the groups which showed statistically significant difference between the four groups. Even in the various zones Glass ionomer cement and Glass ionomer cement with fluoride varnish showed the least demineralization compared to plain composite.

Authors: MR Divyalakshmi , BN Padmavathi , SY Rajan
Published: November 2024

OBJECTIVE About 3 of the malignancies that occur in the body are found in the oral cavity. A strong correlation between immunoglobulin levels and the progression of cancer has been documented. The present study was undertaken to compare humoral immune response in patients with squamous cell carcinoma of the oral cavity prior to therapy after therapy and with relapse. The study involved 100 patients with oral squamous cell carcinoma among whom 50 patients had not taken any treatment for the neoplasm 25 patients had undergone treatment for the neoplasm by surgery and or radiotherapy andor chemotherapy and 25 patients with recurrence of squamous cell carcinoma. Quantitative estimation of serum IgA was done by immunoturbidimetric method and of serum IgE was done by immunoenzymatic assay.RESULTAND CONCLUSION The results of the present study showed that the serum IgA and IgE levels indicate the humoral immune response and reflect the cellular immune response in carcinoma. Thus serum IgA and IgE levels can be considered as prognostic indicators in squamous cell carcinoma of the oral cavity.

Published: November 2024

The dawn of this century is brightened by the growing understanding and experimentation with stem cells as primary tools in the expanding regenerative medicine and dentistry. Stem cells are primitive cells that can differentiate and regenerate deteriorating cells in different parts of the body such as heart bones muscles nervous system and tooth. Scientists all over the world have been working on possibilities of using these stem cells to regenerate human cells which are damaged due to illness developmental defects and accidents. The practice of dentistry is likely to be revolutionized by biological therapies based on growth and differentiation factors that accelerate andor induce a natural biological regeneration. This article is to give an overview about stem cells in general and in particularly about dental stem cells andregenerative dentistry.

Published: November 2024

Introduction The purpose of this study was to evaluate the use of computer simulation to predict the force and the torsion obtained after the activation of teardrop loops of 3 heights and to compare the results with the results obtained from mechanical testing of specimen of same heights. Methodology Seventy-five retraction loops were divided into 3 groups according to height 6 7 and 8 mm. The loops were subjected to tensile load through displacements of 0.5 1.0 1.5 and 2.0 mm and the resulting forces and torques were recorded. The finite element analysis was performed with Ansys 10. The ideal springs for movement of the mandibular incisors were the teardrop loop of 6-mm height activated 0.5 mm and the teardrop loop of 8-mm height activated 1.0 mm. The ideal springs for the maxillary incisors were the teardrop loops with 7 and 8 mm height activated 1.0 mm. Results and conclusionNo significant differences between experimental and simulation results shows that orthodontist can use computer simulation instead of biomechanical testing for appraising of orthodontic device.nbsp
