Methods for Biomimetic Remineralization of Human Dentine: A Systematic Review

This study aimed to review the laboratory methods on biomimetic remineralization of demineralized human dentine. A systematic search of the publications in the PubMed, TRIP, and Web of Science databases was performed. Titles and abstracts of initially identified publications were screened. Clinical trials, reviews, non-English articles, resin-dentine interface studies, hybrid layer studies, hybrid scaffolds studies, and irrelevant studies were excluded. The remaining papers were retrieved with full texts. Manual screening was conducted on the bibliographies of remaining papers to identify relevant articles. A total of 716 studies were found, and 690 were excluded after initial screening. Two articles were identified from the bibliographies of the remaining papers. After retrieving the full text, 23 were included in this systematic review. Sixteen studies used analogues to mimic the functions of non-collagenous proteins in biomineralization of dentine, and four studies used bioactive materials to induce apatite formation on demineralized dentine surface. One study used zinc as a bioactive element, one study used polydopamine, and another study constructed an agarose hydrogel system for biomimetic mineralization of dentine. Many studies reported success in biomimetic mineralization of dentine, including the use of non-collagenous protein analogues, bioactive materials, or elements and agarose hydrogel system.     

Energy based method for numerical fatigue analysis of multidirectional carbon fibre reinforced plastics

Abstract

This paper describes experiments on multiaxial fibre reinforced plastic laminates, which were performed to obtain calibration data for numerical fatigue analyses. For this purpose, fatigue tests of laminates with multidirectional layers subjected to constant amplitude and block loading (0?≤?R?<?1 or R>1) were analysed. The presented simulation results display the fatigue behaviour of carbon fibre reinforced plastics for unidirectional loading conditions and a selected laminate.     

Groundwater salinisation on atoll islands after storm‐surge flooding: modelling the influence of central topographic depressions

Fresh groundwater lenses (FGLs) are of utmost importance for human survival on small and isolated atolls. This article examines saline damage to atoll FGLs from wave washover caused by storm surge and studies the particular influence of central topographic depressions (CTDs). We model storm surge over atoll islets of contrasting widths (400 and 800 m), both with and without CTDs of various sizes. Three key findings emerge. First, under equilibrium undisturbed conditions, the CTD slightly reduces the size of the FGL compared to atoll islets without this feature. Second, during marine flooding, prior saturated conditions at the base of a CTD impede seawater infiltration into the substrate, thereby limiting saline damage in that location. Third and most crucial, however, the amount of salt accumulated within the CTD is significant, ranging from 2 to 10 times higher than the net subsurface infiltration during the period of the storm inundation.     

American Symbolism in Intercultural Communication: An Animosity/Ethnocentrism Perspective on Intergroup Relations and Consumer Attitudes

What leads to acceptance versus rejection of messages that represent one's own culture/in‐group, or a foreign culture/out‐group? We investigate how symbols in mass communication might be used to overcome biases toward in‐group and out‐group messages. We experimentally study these effects across countries representing varying levels of consumer ethnocentrism (which relates to attitudes about one's own country, or in‐group) and country‐specific animosity (which relates to attitudes about a particular foreign country, or out‐group). We select 4 countries based on varying levels of ethnocentrism and U.S.‐focused animosity. Using a Social Identity perspective, we find support for asymmetries of response regarding in‐group preference and out‐group discrimination within the context of U.S. and indigenous cultural representations in the form of symbols and brands.     

Microcosm investigations of phthalate behaviour in sewage treatment biofilms

Discharge from sewage works has been shown to be an important source of phthalates into the environment which is of major concern because some are toxic, suspected endocrine disruptors and recalcitrant. Laboratory trickle filter microcosms (continuous and re-circulating flow) were constructed and operated to investigate the biodegradation and adsorption of phthalates and also to isolate phthalate degrading microorganisms. It was found that adsorption was critical for the removal of both DEP (77.5%) and DEHP (55.7%) in continuous flow microcosms. The proportion of phthalates removed by biodegradation in the continuous flow microcosms was estimated. Re-circulating flow microcosms improved the removal of DEHP compared to continuous flow microcosms. Microcosm biofilm used for an enrichment culture on phthalate media isolated a varied group of microbes including Gram negative and Gram positive bacteria, yeasts and fungi. Bacteria species with all the necessary enzymes to degrade phthalic acid were isolated.     

Experimental solid–liquid equilibria and solid formation kinetics for carbon dioxide in methane for LNG processing

In cryogenic liquefaction processes, CO₂ poses a solid-formation risk even in trace concentrations. We present solid–fluid equilibrium (SFE) data for CO₂ in liquid methane at CO₂ concentrations from (52 to 500) ppm, extending the available data and indicating that models tuned to existing data over predict the solubility of CO₂ at LNG storage temperatures (~112 K) by nearly a factor of 3. The new data are used to improve the SFE model in the ThermoFAST software package. The formation kinetics of CO₂ solids in liquid methane are elucidated at conditions relevant to cryogenic gas processing. Repeated, ramped-temperature formation measurements provide a statistical basis for quantifying solidification risk. Nucleation rates extracted from the ramped-temperature data, consistent with those measured at fixed temperature, were used to extract parameters describing CO₂ solid formation in methane. These results significantly improve the ability to predict CO₂ solid formation risk in cryogenic natural gas processing.     

EXAMINATION OF FERMENTED CIDER VOLATILES FOLLOWING CONCENTRATION ON THE POROUS POLYMER PORAPAK Q

The volatiles in the air above cider have been collected on Porapak Q, regenerated and examined by capillary column gas chromatography and gas chromatography-mass spectrometry. The composition of the extract differs from that obtained from distillation and extraction techniques giving increased relative concentrations of non-polar components. 105 peaks were detected and 59 components identified. Several of these have not previously been reported in ciders.     

Zusammenhänge zwischen Eigenschaften,Rohstoffkomponenten und dem Dichteprofil von Spanplatten

The majority of industrially produced particleboards are sanded before delivery. Sanding losses have to be kept at a minimum and board symmetry must be maintained, particularly in higher density surfacelayers. Stillunknown, however, ishow sanding losses vary per side and how board symmetry and board properties are affected. Laboratory model boards were used to show how density profiles, abrasíon thickness and weight precentage can be determined for every side by comparison before and after sanding. Thus for industrial production accurate sanding control is possible and, when testing bending strength and MOE, an estimation of the changes in these properties.     

Prevalence of Helicobacter pylori(Hp) infection in the department of gastroenterology staff members in Nanjing

The intraneural ganglion of the peroneal nerve is a rare lesion. The differential diagnosis includes lesions of the knee especially the tendinopathia of the knee flexors. Clinical examination, electrophysiological investigations, ultrasound imaging and magnetic resonance tomography will establish the diagnosis. We report a case in which an artificial puncture of the ganglion caused a temporary peroneal palsy. Surgical procedure led to complete restoration of the nerve function.
