Evaluation of the Milled and Three-Dimensional Digital Manufacturing, 10-Degree and 20-Degree Preparation Taper, Groove and Box Auxiliary Retentive Features, and Conventional and Resin-Based Provisional Cement Type on the Adhesive Failure Stress of 3 mm Short Provisional Crowns

Background This study evaluated the effects of milling (CADCAM), 3D printing, preparation taper angles (10-degree and 20-degree), auxiliary retentive features (groove and box), and provisional cement types (conventional and resin-based) on the adhesive failure stress of 3-mm short provisional crowns (PC). The research was motivated by the need to understand how digital dentistry technologies impact the retention and durability of provisional crowns. Material/Methods A total of 160 working models (3D-printed) and PCs [80 milled (CopraTemp)/80 printed (Asiga)] were fabricated from two 10- and 20-degree typodont master models and two 20-degree 3D-printed master models (groove and box), simulating a 3 mm high all-ceramic short PC. After provisional cementation with conventional (Kerr TempBond) and resin-based (ProviTemp) cements, 16 subgroups (n=10 each) underwent thermocycling (10 000 cycles; 5–55°C) and pull-off tests on a universal testing machine. Statistical analysis was performed using one-way ANOVA and post hoc Tukey test. Results Conventional cement failed at lower stress for milled (47.68 to 73.54) and printed (48.40 to 77.91) as compared to resin cement for milled (104.2 to 137.27) and printed (184.85 to 328.84), respectively, with significant differences. Increased taper and groove decreased failure load except for the printed PC/resin cement combination. Use of proximal box preparation increased retention significantly. Except for 20-degree taper cemented with conventional cement, the differences in auxiliary retentive features for milled and printed provisional crowns were statistically significant at P≤0.05. Conclusions 3D-printed PC, resin-based cement, 10-degree taper, and proximal box preparation were associated with higher retention than milled, conventional cements, 20-degree taper, and vertical groove.

A High-Precision Bandgap Reference with Chopper Stabilization and V-Curve Compensation Technique

The MEMS sensor converts the physical signal of nature into an electrical signal. The output signal of the MEMS sensor is so weak and basically in the low-frequency band that the MEMS sensor interface circuit has a rigorous requirement for the noise/offset and temperature coefficient, especially in the bandgap reference block. However, the traditional amplifier has low-frequency noise and offset voltage, which will decrease the precision of the bandgap reference. In order to satisfy the need of the MEMS sensor interface circuit, a high-precision and low-noise bandgap reference is proposed in this paper. A novel operational amplifier with a chopper-stabilization technique is adopted to reduce offset and low-frequency noise. At the same time, the V-curve compensation circuit is used to realize the second-order curvature compensation. The circuit is implemented under the 0.18 μm standard of the CMOS process. The test result shows that the temperature coefficient of the bandgap is 2.31 ppm/°C in the range of −40–140 °C, while the output voltage noise is only 616 nV/sqrt(Hz)@1 Hz and the power-supply rejection ratio is 73 dB@10 kHz. The linear adjustment rate is 0.33 mV/V for supply voltages of 1.2–1.8 V at room temperature, the power consumption is only 107 μW at 1.8 V power supply voltage, and the chip active area is 0.21 × 0.28 mm2.
Modulation of the Immune Response to Allergies Using Alternative Functional Foods

Modulation of the allergic immune response through alternative therapies is a field of study that aims to address allergic reactions differently from traditional approaches. These therapies encompass the utilization of natural functional foods, which have been observed to exert an influence on the immune response, thus mitigating the severity of allergies. Indeed, some studies suggest that the incorporation of these nutraceuticals can regulate immune function, leading to a reduction in histamine release and subsequent alleviation of allergic symptoms. Moreover, certain herbs and dietary supplements, such as curcumin, are believed to possess anti-inflammatory properties, which may serve to moderate allergic responses. Although the results remain somewhat mixed and require further research, these alternative therapies exhibit the potential to impact the allergic immune response, thereby providing complementary options to conventional treatments. Therefore, in this review, we aim to provide an updated account of functional foods capable of modulating the immune response to allergies. In that sense, the review delves into functional foods sourced from plants (phytochemicals), animals, and marine algae. Emphasis is placed on their potential application in the treatment of allergic disorders. It also provides an overview of how these foods can be effectively utilized as functional foods. Additionally, it explores the molecular mechanisms and scientific validity of various bioactive natural compounds in the management of allergies.
Location Accuracy Indicator Enhanced Method Based on MFM/PDR Integration Using Kalman Filter for Indoor Positioning

Based on the complementary advantages of integrated positioning methods, the multisource integrated positioning technology has become one of the mainstream technologies in the field of indoor navigation and positioning. However, little literature is available on the estimating for positioning accuracy of different sources in the integration. The negative benefits of integrated positioning method are caused by inaccurately estimated accuracy, which frequently occur in two sources integrated positioning without any correction. To study how to estimate the positioning accuracy of different sources in the integration, we propose a location accuracy indicator enhanced method based on magnetic field matching (MFM) and pedestrian dead reckoning (PDR) integration using Kalman filter (KF): the prior covariance based on PDR and the posterior covariance based on MFM are adopted to calculate noise matrixes of the KF and established the location accuracy indicator enhanced filtering system. From the results, the proposed method, which was less affected by changing the matching range of the magnetic field and broadening the interval of the fingerprint database, obtained 2.746 and 1.881 m for 90% error and root-mean-square error (RMSE), respectively, and the error was 24%–27% lower than the best empirical model, including weighted nearest ${k}$ -neighborhood (WKNN)/PDR (3.776 and 2.523 m) and integrated weight nearest neighborhood (IWNN)/PDR (3.712 and 2.485 m). It was verified by the experiments that the proposed method could accurately calculate noise matrixes of the KF and provide accurate weights, having stronger positioning performance and robustness than the others.
Random biological activities in relation to physico-chemical parameter of shallow water in catchment area of Bhopal’s upper lake

Freshwater resources are considered to be the wealth of Nation. Urbanization, agricultural and uncontrolled anthropogenic activities leads to the nutrient accumulation, silt and sediment deposition, and addition of organic matter in the lake from the catchment area in the aquatic ecosystems causing their deterioration and caused them to lose their importance. As the biological activities of lakes or any water body is largely depending upon its water quality in varied aspects, thus, present investigation is aimed at instantaneous existence of interdependent physico-chemical hydrological quality to various life forms of Bhopal’s upper lake to understand the level pollution due to anthropogenic regions. Temperature, pH, transparency, total hardness, nitrates, phosphates, biological oxygen demand were measured for water samples collected from four sites, Boat club, Koh-e-Fiza, Karbala and Bairagarh region designated as S-1, S-2, S-3 and S-4 respectively. Occurrence of aquatic plants Eichhornia crassipes, Pistia stratiotes, Ceratophyllum demersum, Eleodea Canadensis and Azolla spp. ; algal species Anabaena sp. , Microcystis aeroginosa, Oscillatoria tenuis and Chlorella spp. ;ornamental fishes Trichogaster lalius, Trichogaster fasciata, and Badis badis; and snails were noticed at random in relation to the current physico-chemical conditions of water that were supporting the flourishing of such biological forms in the sites.

Seismic image of the Cantabrian Mountains in the western extension of the Pyrenees from integrated ESCIN reflection and refraction data

Integrated analysis of normal-incidence and large-aperture seismic reflection data collected in 1992 and 1993 within the Spanish ESCIN and complementary projects provide a first complete N-S crustal transect across the Northern Iberian Peninsula and continental margin. Images of the crustal structure of the Cantabrian Mountains and their transition to the Duero basin and to the Cantabrian margin are obtained from: (a) a 65-kin-long vertical reflection profile ESCIN-2 on land; (b) a 200-km-long reversed refraction profile; and (c) wide-angle recordings of the marine ESCIN-4 profile. Consistent results between reflectivity pattern and velocity--depth distribution reveal important lateral variations in the deep structure. The reflective crust imaged in the ESCIN-2 profile changes its attitude from sub-horizontal beneath the Duero basin to north-dipping beyond the Mountain front. Basement thrusts are observed in the upper crust merging into a detachment at 6 s (TWT) and may have triggered the Alpine uplift of the range. The Moho is identified at the bottom of the reflective lower crust and deepens from 12 to 15 s at the northern end of the profile, about 35 km inland. Modelling of the refraction data laterally extends the seismic image and provides evidence for Variscan crustal features beneath the Duero basin. Northwards, the velocity in the lower crust decreases and the Moho, constrained by the wide-angle data from profile ESC1N-2, deepens to about 60 km ending abruptly at the shoreline. The velocity-depth model is constrained along the Asturian platform up to the continental slope, where the crust-mantle boundary is located at 24 km depth. This 'margin Moho' shows a progressive deepening southwards, and extends to the coast where it is found at 30 km depth. The present seismic data support an important Alpine reworking and thickening of the crust under the Cantabrian Mountains. The onshore/offshore transition is marked by an imbrication of two crusts of very different thicknesses. This signature offers a strong parallelism with the one previously observed further east across the Pyrenees in the ECORS seismic profile.

Hydrogen production and hydrogen utilization in the rumen: key to mitigating enteric methane production

Molecular hydrogen (H2) and formate (HCOO−) are metabolic end products of many primary fermenters in the rumen ecosystem. Both play a vital role in fermentation where they are electron sinks for individual microbes in an anaerobic environment that lacks external electron acceptors. If H2 and/or formate accumulate within the rumen, the ability of primary fermenters to regenerate electron carriers may be inhibited and microbial metabolism and growth disrupted. Consequently, H2- and/or formate-consuming microbes such as methanogens and possibly homoacetogens play a key role in maintaining the metabolic efficiency of primary fermenters. There is increasing interest in identifying approaches to manipulate the rumen ecosystem for the benefit of the host and the environment. As H2 and formate are important mediators of interspecies interactions, an understanding of their production and utilization could be a significant starting point for the development of successful interventions aimed at redirecting electron flow and reducing methane emissions. We conclude by discussing in brief ruminant methane mitigation approaches as a model to help understand the fate of H2 and formate in the rumen ecosystem.
Water quality assessment in Bangwe Township, Blantyre City, Malawi

This study assessed microbial contamination of water in sources (boreholes and open wells) and selected households in four Malawian villages (situated in Bangwe Township, Blantyre city) by analyzing the presence of faecal coliforms using membrane filtration. Additionally, pH, conductivity and temperature of the water sources were also determined. Conductivity ranged from 150.5 to 1575 μS/cm. About 70% of all water sources were above World Health Organization (WHO) and Malawi Bureau of Standards (MBS) limits for conductivity (indicating salty water in the area). Water temperature ranged from 21.5 to 24.7°C and pH from 5.28 to 6.95 with no significant difference (p > 0.05) for these physical parameters among the sampling points. Water pH was within MBS range while 60% of water sources were below WHO range. Faecal coliform levels exceeding WHO and MBS safe standards were observed in 79% of all samples analysed in this study. Mean household faecal coliform levels were as follows (village (mean)); Nalivata (437 CFU/100 mL), Mpingwe 1 (172 CFU/100 mL), Mpingwe (266 CFU/100 mL) and Salvation Army (15 CFU/100 mL). All mean faecal coliform counts were above WHO (0 CFU/100 mL) and MBS (0 CFU/100 mL) safe values. The results suggest that the quality of water in the villages often fails to meet one or more WHO and MBS recommended safe levels as such, poses a potential risk to the health of those individuals living in such villages. Local and National Governments should therefore target the provision of safe water to such populations. The findings of this study also highlight the need for improved dissemination of good hygienic practices amongst such communities. Key words: Boreholes, drinking water, faecal coliforms, health, pollution.
The Educational and Health Impact of COVID-19 on Children With Special Needs: A Systematic Review

RESEARCH OBJECTIVE: Governments across the world were forced to impose social distancing and lockdown measures to prevent the spread of COVID-19, caused by coronavirus SARS-CoV-2 that emerged in December 2019. Following the declaration of COVID-19 as a pandemic, the disruptions, including restrictive measures such as school closures had severe impacts on the physical, emotional and mental health of all people, especially children with special needs. There was also scant data, particularly in low-to-middle-income countries. Existing literature stems mostly from western countries, thus the need to perform a comprehensive review on this topic. THE RESEARCH PROBLEM AND METHODS: The primary objective of the systematic review is to understand the impact of COVID-19 and restrictive measures such as school closures on the educational outcomes and physical and mental health of school-going children with special needs. THE PROCESS OF ARGUMENTATION: This systematic review used the PRISMA 2020 checklist where four databases and grey literature were searched for full text articles, peer reviewed publications in the English language that were published during January 2019–December 2021. RESEARCH RESULTS: The literature search identified 1294 publications, of which 25 key papers were selected. These studies investigate the impact on children with special needs across the globe, with a majority of papers from Europe. We found that COVID-19 and the digitalization of schooling had severe impacts on the physical and mental health of children with special needs and their parents/caregivers. CONCLUSIONS, RECOMMENDATIONS AND APPLICABLE VALUE OF RESEARCH: These studies highlight the need for an inclusive school environment to ensure that the learning outcomes for children everywhere are achieved. Further, a hybrid model that includes classroom learning with novel inventive methods would be beneficial for children with special needs.

Colección Iris Scaccheri: en busca del archivo perdido

El cuerpo, la conservación y la memoria: estos tres ejes se articulan para pensar la Colección Iris Scaccheri, compilación inédita de la coreógrafa, bailarina y poeta de la danza platense. A partir de fuentes primarias (textos, ensayos y obras en video, programas de mano) y secundarias (testimonios, fotos y recortes periodísticos) nos preguntamos por la conformación de un archivo (Glozman, 2018-2020; Tambutti, 2019; Lepecki, 2013) en la historiografía local. Tomando en cuenta tanto la diversidad de materiales como los criterios de organización y de selección que toda narrativa supone, reflexionamos sobre los lugares comunes y fuera de serie a la hora de sistematizar el proceso de producción de una artista particular dentro de una periodización local. En consecuencia, Scaccheri se posiciona como una outsider (Becker, 2009) cuya poética ‘dislocada, impertinente e inespecífica’ nos permite pensar en el cuerpo como el lugar intermedial por excelencia a la hora de pensar no solo como objeto de estudio de la danza sino las artes, así como sus espacios comunes para ocupar y revisar la memoria.
Depth-based defocus elimination for macroscopic Fourier ptychography imaging

To achieve high-resolution intensity images, Fourier ptychography (FP) has been used in microscopic for decades, and is suitable for macroscopic area. Aberration is important for the quality of reconstruction during aperture scanning and phase recovery in the FP process. In the field of macroscopic imaging, due to the defocus in the 3D scene, cameras can only capture blurry images by direct photography. To overcome the limitation, we design an FP iteration method with the depth of defocus to improve the recovery for the high-resolution images. The initial scene comprises two layers of data: the intensity information and the depth map. The spectral distribution and optical transfer function are acquired via Fourier transform. This is followed by an iterative process of reconstruction: a low-resolution image is taken at each aperture, combined with depth-induced defocus aberrations, and then substituted into optical transfer function calculations to simulate intensity measurements from camera sensing. Each scan corresponds to a specific area with limited bandwidth in Fourier space, and multiple iterations are used for phase recovery to reconstruct a high-resolution image. Compared to the traditional method, the defocus elimination FP algorithm for macroscopic imaging enhances the resolution and contrast of the reconstruction, enabling a wider range of measurable scenarios.
