Investigation of the Pull-Out Behaviour of Metal Threaded Inserts in Thermoplastic Fused-Layer Modelling (FLM) Components
Authors: Kastner Tobias , Troschitz Juliane , Vogel Christian , Behnisch Thomas , Gude Maik , Modler Niels
Published: February 2023

To provide detachable, secure and long-term stable joints in fused-layer modelling (FLM) components or assemblies, metal threaded inserts are widely used as extrinsic interfaces. However, the load-bearing capacity of such inserts is influenced by the inhomogeneous, anisotropic material structure of the FLM components. This work evaluates the influence of the joining zone design and the printing process parameters on the achievable joint properties. Therefore, we printed thermoplastic FLM test specimens with varying parameters for infill density, wall thickness, layer height and nozzle temperature. Subsequently, metal threaded inserts were warm-embedded into the test specimens and investigated in quasi-static pull-out tests. The results show that the infill density in the joining zone has the largest impact on the joint strength and should be 70% or higher. Furthermore, an analysis of different wall thicknesses around the pre hole shows that a minimum value of 2.4 mm is required for the selected insert geometry to achieve a high pull-out force. Increasing the wall thickness beyond this value does not significantly affect the joint strength. The results provide an improved base for detailed understanding and interface design in FLM components for the integration of metal threaded inserts as well as for further investigations regarding different printing materials and load types.

Published: February 2023

In this work we report the characterization of thin metallic coatings of interest for nuclear fusion technology through the ns double-pulse LIBS technique. The coatings, composed of a tungsten (W) or tungsten-tantalum (W-Ta) mixture were enriched with deuterium (D), to simulate plasma-facing materials (PFMs) or components (PFCs) of the next generation devices contaminated with nuclear fuel in the divertor area of the vacuum vessel (VV), with special attention to ITER, whose divertor will be made of W. The double pulse LIBS technique allowed for the detection of D and Ta at low concentrations, with a single laser shot and an average ablation rate of about 110 nm. The calibration free (CF-LIBS) procedure provided a semi-quantitative estimation of the retained deuterium in the coatings, without the need of reference samples. The presented results demonstrate that LIBS is an eligible diagnostic tool to characterize PFCs with high sensitivity and accuracy, being minimally destructive on the samples, without PFCs manipulation. The CF-LIBS procedure can be used for the search for any other materials in the VV without any preliminary reference samples.

Published: February 2023

The surface treatment of concrete enhances the bonding of its metal coatings. Therefore, in the present study, on the concrete surface, prior to the deposit of an 85Zn-15Al coating via an arc thermal spraying process, different surface treatments were considered for the effective electromagnetic pulse (EMP) shielding properties of the concrete. However, the direct coating on a concrete surface possesses lower bond adhesion, therefore it is of the utmost importance to treat the concrete surface prior to the deposition of the metal coating. Moreover, to obtain better bond adhesion and fill the defects of the coating, the concrete surface is treated by applying a surface hardener (SH), as well as a surface roughening agent (SRA) and a sealing agent (SA), respectively. The metal spraying efficiency, adhesion performance, and bonding strength under different concrete surface treatment conditions were evaluated. The EMP shielding effect was evaluated under the optimal surface treatment condition. The proposed method for EMP shielding exhibited over 60% of spraying efficiency on the treated surface and a bonding strength of up to 3.9 MPa for the SH–SRA–SA (combining surface roughening and pores/defects filling agents) specimen compared to the control one, i.e., 0.8 MPa. The EMP shielding values of the surface-treated concrete with surface hardener, surface roughening agent, and sealing agent, i.e., SH–SRA–SA specimens, exhibited 96.6 dB at 1000 MHz. This was about 12 times higher than without coated concrete.

The aim of this in vitro study is to try to identify a treatment in the field of professional oral hygiene techniques that is ideal and less invasive with regard to prosthetic restorations, chosen in lithium disilicate and feldspar ceramics. Seventeen veneers were prepared (eight in lithium disilicate and nine in feldspar ceramic) and each of them was attached to an extracted tooth. The treatment groups were initially contaminated in the Microbiology Laboratory of Università Vita—Salute San Raffaele. After 24 h they were treated with four different methods of professional oral hygiene and were then sent to the Microscopy Laboratory, in which they were analysed by SEM, with 180X, 250X, and 500X magnification, to assess any damage caused to the treated surfaces. The SEM analysis produced 64 images that were evaluated by an experienced dentist, and the use of the prophetic cup seemed to be the most suitable among the evaluated treatments. However, from a microbiological point of view, this method was the least effective in terms of reducing bacterial growth. In this regard, the use of a prophylactic rubber cup combined with a 0.20% chlorhexidine gel is recommended during professional oral hygiene sessions for the maintenance of aesthetic prosthetic restorations.

Published: February 2023

In recent years, several studies have reported the recycling of by-products generated by the paper industry and their application to the construction industry. A majority of the existing studies used waste paper sludge ash, and considerable energy is consumed in such incineration processes. This may further contribute to air pollution. In this study, we used waste newspaper (WNP), which underwent a simple crushing process without a separate high-temperature treatment process, and we integrated it in cement mortar. We prepared mortars containing 0%, 0.2%, 0.4%, 0.6%, 0.8%, and 1.0% ground WNP as a cement substitute. Subsequently, the fluidity, compressive strength, tensile strength, carbonation depth, drying shrinkage, and microstructure of the mortars were compared and analyzed. The 28-day compressive strength of the mortar samples with WNP was approximately 3.2–16.1% higher than that of the control sample. The 28-day accelerated carbonation depth of the samples with WNP was approximately 1.03–1.61 mm. Furthermore, their carbonation resistance was approximately 5.2–39.4% higher than that of the control sample. Compressive strength, tensile strength, and carbonation resistance were improved by appropriately using ground WNP as a cement substitute in cement mortar. In this study, the appropriate amount of WNP according to the mechanical properties of cement mortar was found to be 0.4–0.8%, and considering the durability characteristics, the value 0.6 was the most ideal.

In the present study, a diagnostic approach was used to analyze the wall painting in the apse of the Sotterra church at Paola, in the province of Cosenza, Italy. The Sotterra church is nowadays located 6 m under the ground level. The presbytery area houses valuable pictorial evidence attributable to different phases. The oldest painting, visible in the apse area, dates back to the 11th–12th centuries, and it represents the subject of the present study, while the later decorations are placed in a chronological range from the 14th to the 15th centuries. Due to the peculiar environmental conditions, the conservation of subterranean sites represents a debated issue and must be properly investigated. For this reason, in this research, noninvasive analysis and laboratory-based methods were planned to obtain information about both the composition of original materials and the mechanisms and causes of alterations affecting the wall painting in the apse. Simultaneously, an environmental monitoring campaign of the indoor climate for the duration of nine months was conducted. The results highlighted the use of natural mineral pigments such as ochres and earths. The analysis of the painting stratigraphy revealed that the mural painting consists of two plaster layers characterized by lime-based binder. Moreover, the presence of a high amount of calcium sulfate has been discovered; this latter result, combined with the monitoring of the microclimate, allowed for the establishment of the crystallization and the condensation risks which occur on the investigated surfaces.

Published: February 2023

Hybrid polysiloxanes and polysilsesquioxanes grafted with naturally occurring bioactive phytochemicals: eugenol and linalool, were synthesized and investigated with regard to their structure and properties. The two series of materials, differing in the type of inorganic structure and the content of active groups, were coated onto the surface of glass plates, and their antibiofilm activities against bacteria Aeromonas hydrophila were assessed by luminometry and fluorescence microscopy. Bioactivity was correlated with specific properties of the hybrid coatings (chemical structure, surface free energy and adhesiveness). The functionalized polysilsesquioxanes exhibited the most favorable anti-adhesive effects. Cell adhesion after 6 days of incubation, expressed as RLU/cm2, was significantly reduced (44 and 67 for, respectively, Z-E-100 and Z-L-100, compared to 517 for the control glass carrier). The surface stickiness of polysiloxane films deteriorated their anti-adhesion properties, despite the presence of a large amount of bioactive species.
Multi-Wavelength Photoacoustic Temperature Feedback Based Photothermal Therapy Method and System

Published: February 2023

Photothermal therapy (PTT) is a new type of tumor treatment technology that is noninvasive, repeatable, and does not involve radiation. Owing to the lack of real-time and accurate noninvasive temperature measurement technology in current PTT surgical procedures, empirical and open-loop treatment laser power control mode inevitably leads to overtreatment. Thermal radiation causes irreversible damage to normal tissue around cancer tissue and seriously affects the therapeutic effect of PTT and other therapies conducted at the same time. Therefore, real-time measurement and control of the temperature and thermal damage of the therapeutic target are critical to the success of PTT. To improve the accuracy and safety of PTT, we propose a multi-wavelength photoacoustic (PA) temperature feedback based PTT method and system. PA thermometry information at different wavelengths is mutually corrected, and the therapeutic light dose is regulated in real time to accurately control the treatment temperature. The experimental results on the swine blood sample confirm that the proposed method can realize real-time temperature measurement and control of the target area with an accuracy of 0.56 °C and 0.68 °C, demonstrating its good prospects for application.
Investigation of the Influence of the Mixing Process on the Powder and Component Properties during Cyclic Reuse of a Polyamide 12 Sinter Material in Selective Laser Sintering
Authors: Eggers Tom , von Lacroix Frank
Published: February 2023

Selective laser sintering (SLS) with polymers is currently in transition to the production of functional components. Nevertheless, the potential to revolutionize conventional production processes is confronted by newly imposed requirements regarding reliability and reproducibility. To ensure that the requirements are fulfilled, the aging mechanisms occurring in polymers are compensated by recycling strategies, such as fraction-based mixing of a defined ratio of new with recycled powder. Although various mixing ratios for the reuse of the material in SLS have been investigated, there is insufficient knowledge of suitable mixing parameters for homogeneous and gentle mixing of the powder fractions. This work therefore focused on the influence of potentially suitable mixing parameters identified in a previous study on the ongoing powder and component properties in SLS using polyamide 12 and a constant refreshing rate. Regarding the powder properties, the intrinsic properties and density of the powders were investigated. Regarding the component properties, mechanical properties, sinter density, and surface quality were investigated. Decreases in the powder density and the component properties were measured by increasing the number of process cycles. Taking into account the determined powder and component properties, the selected mixing parameters enabled a homogeneous and gentle mixing of the powder fractions.

This work aimed to investigate the antidiabetic, antiglycation, and antioxidant potentials of the ethanol extract of seeds of Passiflora cincinnata (EPCIN) in vitro. The EPCIN was evaluated from the following assays: total phenolic content (TPC – mg of Gallic Acid Equivalents (GAE)/g of dry extract), Radical Scavenging Assays (DPPH•, HOCl-scavenging assay), and protective effects against glycation of bovine serum albumin (BSA) with methylglyoxal (MGO) or a mixture of reducing sugars, fructose and glucose, as well as the potential for MGO capture by derivatization with ortho-phenylenediamine (OPD). To evaluate the antidiabetic activity of EPCIN in vitro, we used the assays of enzymes α-amylase (4 U/mL), α-glucosidase (0.25 U/mL), and dipeptidyl peptidase-4 (DPP-4 – 3.125 mU). The cell viability of EPCIN-pretreated normal human bronchial epithelial cells (BEAS-2B) alone or in the presence of the carcinogen 4-[(acetoxymethyl)nitrosamine]-1-(3-pyridyl)-1-butanone (NNKOAc) was measured using MTS assay. Quercetin (QCT), piceatannol (PIC), acarbose (ACB), and sitagliptin (STG) were used for comparison purposes. EPCIN had an average of TPC 157.0 ± 1.5 mg of GAE/g of dry extract, exhibited IC50 for DPPH• and HOCl of 11.9 ± 1.8 μg/mL and 6.9 ± 0.9 μg/mL, respectively. EPCIN and AMG inhibited the formation of advanced glycation end-products (AGE) with IC50 of 574 ± 8.7 and 31.9 ± 2.7 μg/mL for the initial stage and 542.6 ± 2.7 and 52.8 ± 8.1 μg/mL for the intermediate stage of glycation, respectively. EPCIN showed IC50 for α-amylase and α-glucosidase of 218.2 ± 15.9 μg/mL (p<0,05) and 242.0 ± 25 μg/mL (p<0,05), respectively. EPCIN did not show cytotoxicity for BEAS-2B cells at 10 and 50 μg/mL concentrations. In addition, it was also able to protect cultured human cells from oxidative stress caused by the NNKOAc at 100 μM. The in vitro evidence of the potential antioxidant, antiglycant, and antidiabetic effects warrants further investigation of the antidiabetic potential of Passiflora cincinnata seeds.

The General Data Protection Law (LGPD) aims to bring greater transparency and responsibility to the use of personal data of individuals and legal entities throughout the national territory. With the advent of the Law, the processing of data that was carried out in an uncontrolled way is now regulated and with specific purposes, uniting Brazilian legislation with the global concept of data privacy. Within the scope of the business activity of micro and small companies (MSEs), compliance with the Law can be quite challenging, considering that the planned measures can generate such high costs that these companies need to paralyze their activities. Therefore, the objective of this study is to report on the challenges for the application of the Law in Brazil, with a focus on flexibility for small companies, a sector that has the greatest difficulty in adapting to the norms. And emphasize how the implementation of the Law within organizations can bring opportunities for growth, since the ethical use of data linked to a culture of good practices can increase trust between companies and customers.
UMA PROPOSTA PARA O ENSINO DO EFEITO FOTOELÉTRICO A PARTIR DE UMA CONTEXTUALIZAÇÃO HISTÓRICA
Authors: BONATO GONÇALVES DE CARVALHO RAFAEL
Published: February 2023

The photoelectric effect is an abstract phenomenon that is difficult to observe and understand by students, creating an obstacle to their learning. The photoelectric effect consists of the ejection of electrons from a material exposed to a certain frequency of electromagnetic radiation. The packets of light, called photons, transfer energy to electrons. If this amount of energy is greater than the minimum energy needed to pull out the electrons, they will be pulled from the surface of the material, forming a photoelectron current. This article aims to describe the development, application and evaluation of a proposal for a didactic sequence in a high school class to teach the photoelectric effect, using the History of Science as a knowledge building tool. The strongly technical tradition in the field of Physics is reflected in the initial teacher training, making the learning process mechanistic, led to study and understand only what can be measured. However, the process of teaching physics is a human activity and needs to be analyzed from this perspective. This is the great relevance of approaches with a historical, philosophical and social bias in understanding science not as an entity that knows the whole truth, but as something that has been built over time in the most different possible ways, being subject to changes over time. of new discoveries.

The long-term consequences of early school absences for educational attainment and labour market outcomes
Authors: Dräger Jascha , Klein Markus , Sosu Edward
Published: February 2023

Absences from school can have negative effects on a child's education, including the loss of teacher-led lessons, peer interactions, and, ultimately, academic achievement. However, little is known about the long-term consequences of school absences for overall educational attainment and labour market outcomes. In this paper, we used data from the 1970 British Cohort Study (BCS70) to examine the long-term effects of school absences in late childhood on individuals’ educational attainment, social class, unemployment, and earnings at age 42 while adjusting for a comprehensive set of confounders. Our findings show that school absences are associated with lower educational attainment, but do not affect social class destination except for increasing the likelihood of being out of the labour force after adjusting for confounders. Individuals who missed five days of school at age 10 were 5.7% more likely to have obtained no qualifications and 4.2% more likely to be out of the labour force. However, we did not find a significant impact of school absences on individuals’ earnings or when looking specifically at their time in unemployment over the last 10 years. Our findings suggest that the negative effects of school absences persist beyond schooling into adulthood. Overall, this study highlights the importance of addressing school absenteeism to promote educational and labour market participation over the life course.

Within the global sphere, different phenomena are manifested that can constitute representations of impairment for vulnerable groups. One of these vulnerable groups is the one constituted by the sex-diverse community and an example of the events mentioned is the existence of laws that promote their discrimination. With this essay, it was intended to understand the spectrum of discrimination against the sex-diverse population in the Venezuelan armed forces as a dimension within the framework of the Organic Code of Military Justice, with special reference to its article 565. In this way, it is found that the Venezuelan State does not respect its international commitments in the field of human rights by allowing the segregation of members of the armed forces according to their sexuality, and that the criminalization of their conduct in this sense and with the support of legal norms. It even represents a violation of the rights to the free development of personality and equality, among others.

Abstract: Success of maintaining dental health through the act of brushing teeth is influenced inter alia by right brushing technique. Moreover, improper brushing technique can cause gingival recession. This study aimed to determine the relationship between tooth brushing technique and the occurrence of gingival recession. This was a literature study. Data were obtained from Pubmed, Google Schoolar, and Science Direct databases. After the literatures being selected based on inclusion and exclusion criteria, a critical appraisal was carried out, and seven literatures were obtained consisting of six cross-sectional studies and one descriptive study. The results showed that the most used brushing techniques in the studies were horizontal dan vertical techniques. There were relationships between both techniques and the occurrence of gingival recession, but the worse recession was found in horizontal tooth brushing technique compared to the vertical one. In conclusion, horizontal and vertical brushing techniques could cause gingival recession, albeit, the worse recession was found in horizontal tooth brushing technique.

We examined the effects of the laser scan speed and power on the Sn fraction and crystallinity of GeSn wires of 1 μm width and 1 mm length fabricated by laser-induced local liquid phase crystallization on quartz substrates. The Sn fraction increased from 1% to 3.5% with an increasing scan speed from 5 to 100 μm s−1, corresponding to a luminescence wavelength of 1770–2070 nm. This result can be interpreted as the scan speed dependence of the non-equilibrium degree during crystal growth. The increase in the laser power reduced the Sn fraction and caused a blue shift in the luminescence wavelength. We discuss these phenomena based on the growth kinetics of zone melting.

Background: Saliva acts as a buffer system to maintain the optimal pH of the mouth. The acidic pH of saliva causes demineralization of enamel resulting in dental caries. The bromelain enzyme found in pineapple skin can increase the pH of saliva by inhibiting bacterial growth. This study aims to determine the effect of gargling with pineapple peel extract solution (Ananas comosus(L) Merr) on salivary pH in students of SMPN 3 Bukit Apit.

Methods: This study was using a quasi-experimental method with a pre-test and post-test without a control group design. The research sample was 27 students of SMPN 3 Bukit Apit. The sample was divided into 3 groups of 9 students eacof h who met the inclusion criteria. Group 1 rinsed with 25% pineapple peel extract, growas up 2 rinsed with 50% pineapple peel extract, solution and group 3 rinsed with distilled water. Salivary pH was measured using a digital pH meter before rinsing, after rinsing for 3 minutes, after rinsing for ,15 minutes and after rinsing for 30 minutes. Data were analyzed by t Test followed by ANOVA test

Results: There was a significant effect (p<0.005) of gargling with pineapple peel extract solution on the pH of saliva. The concentration of the pineapple peel extract solution that had the most effect on salivary pH was the concentration of 50%.

Conclusion: Gargling with a solution of pineapple peel extract can increase the pH of oral saliva.

Emergent Causality & the Foundation of Consciousness
Authors: Bennett Michael Timothy
Published: February 2023

To make accurate inferences in an interactive setting, an agent must not confuse passive observation of events with having participated in causing those events. The ``do'' operator formalises interventions so that we may reason about their effect. Yet there exist at least two pareto optimal mathematical formalisms of general intelligence in an interactive setting which, presupposing no explicit representation of intervention, make maximally accurate inferences. We examine one such formalism. We show that in the absence of an operator, an intervention can still be represented by a variable. Furthermore, the need to explicitly represent interventions in advance arises only because we presuppose abstractions. The aforementioned formalism avoids this and so, initial conditions permitting, representations of relevant causal interventions will emerge through induction. These emergent abstractions function as representations of one’s self and of any other object, inasmuch as the interventions of those objects impact the satisfaction of goals. We argue (with reference to theory of mind) that this explains how one might reason about one's own identity and intent, those of others, of one's own as perceived by others and so on. In a narrow sense this describes what it is to be aware, and is a mechanistic explanation of aspects of consciousness.
