Abstract Removable partial dentures (RPDs) are traditionally made using a casting technique. New additive manufacturing processes based on laser sintering has been developed for quick fabrication of RPDs metal frameworks at low cost. The objective this study was to characterize the mechanical, physical, and biocompatibility properties RPD cobalt–chromium (Co–Cr) alloys produced by two laser‐sintering systems compare them those prepared traditional methods. laser‐sintered Co–Cr were processed...
In this study we designed a cost-effective reverse osmosis (RO) desalination unit integrated with solar photovoltaic (PV) energy source for Masdar Institute of Science and Technology. The proposed system does not rely on expensive batteries or extra land drastically decreases the government expenses to subsidize water production cost by $ 1.34 /m3. addition, reduces GHG emissions 361 tCO2 annually. equity payback period was found be 25 years. Comparing results obtained conventional values,...
Background: This study aimed at investigating the prolonged effects of glucocorticoids and bisphosphonates on bone. Methods: Six-to-eight-month-old skeletally mature male Sprague Dawley rats were randomized to receive a cancer therapy combination zoledronic acid (ZA = 0.13 mg/kg) dexamethasone (DX 3.8 (treatment group, n 10) or sterile phosphate buffer saline solution (control 10). The received weekly intraperitoneal injections for 8 weeks, which stopped 6 weeks before euthanasia....
Carbon fiber reinforced polymer (CFRP) composites are increasingly utilized for their lightweight and superior mechanical properties. This study uses machine learning models to predict the properties of CFRP based on volume fraction carbon nanotubes (CNTs), interlayer fraction, glass transition temperature, manufacturing pressure. Sixty-two samples covering nine different types CFRPs were designed, manufactured, experimentally tested. Three models, namely ridge regression, random forest,...
Chirality seems to play a key role in mineralization. Indeed, biominerals, the biomolecules that guide formation and organization of inorganic crystals help construct materials with exceptional mechanical properties, are homochiral. Here, we show addition homochiral l-(+)-tartaric acid improved properties brushite bioceramics by decreasing their crystal size, following classic Hall-Petch strengthening effect; d-(-)-tartaric had opposite effect. Adding l-(+)-Tar increased both compressive...
Bone is a hierarchically organized biological material, and its strength usually attributed to overt factors such as mass, density, composition. Here we investigate covert factor - the topological blueprint, or network organization pattern of trabecular bone. This generally conserved metric an edge-and-node simplified presentation bone relates average coordination/valence nodes equiangular 3D offset trabeculae emanating from these nodes. We compare blueprint in presumably normal, fractured...
Designing a synthetic crown is time-consuming, inconsistent, and labor-intensive process. In this work, we present fully automatic method that not only learns human design dental crowns, but also improves the consistency, functionality, esthetic of crowns. Following success in point cloud completion using transformer-based network, tackle problem generation as point-cloud around prepared tooth. To end, use geometry-aware transformer to generate Our main contribution add margin line...
During a crown generation procedure, dental technicians depend on commercial software to generate margin line define the design boundary for crown. The remains non-reproducible, inconsistent, and challenging procedure. In this work, we propose points prepared teeth meshes using adaptive point learning inspired by AdaPointTr model. We extracted ground truth lines as clouds from bottom meshes. chamfer distance (CD) infoCD loss functions were used training supervised deep model that outputs...
Natural biominerals, such as bones and teeth, use acidic matrix biomolecules to control growth, morphology, organization of the brittle hydroxyapatite crystals. This interplay provides biominerals with outstanding mechanical properties. Recently, we reported that l-enantiomer chiral tartaric acid has a potent regulatory effect on crystal structure performance brushite cement, mineral monoclinic system. We hypothesized this strategy could be applied using various α-hydroxycarboxylic acids...
Dental offices tackle thousands of dental reconstructions every year. Complexity and abnormalities in dentition make segmentation an optical scan a challenging manual task that takes 45 minutes on average. The present work improves the generalization currently available deep learning model 3D arches by introducing new loss function to leverage unlabeled data. semi-supervised network is trained using joint combines supervised annotated input self-supervised non-labeled input. Our results...
A cohesive zone damage-healing model (CZDHM) derived based on the laws of thermodynamics for self-healing materials is presented. The well-known nominal, healing, and effective configurations classical continuum damage mechanics are extended to materials. new physically-based internal crack healing state variable proposed describing evolution within zone. effects temperature, crack-closure, resting time behavior discussed. Numerical examples conducted show various novel features formulated CZDHM.
Automatic and accurate dental arch segmentation is a fundamental task in computer-aided dentistry. Recent trends digital dentistry are tackling the design of 3D crowns using artificial intelligence, which initially requires proper semantic teeth from intraoral scans (IOS). In practice, most IOS partial with as few three on scanned arch, some them might have preparations, missing, or incomplete teeth. Existing deep learning-based methods (e.g., MeshSegNet, DArch) were proposed for...
Scarcity of potable water causes a serious problem in arid regions the world where freshwater is becoming insufficient and expensive. Warm Middle East North Africa are considered among severest shortage places.

Thin film evaporation is investigated in microchannel membranes for solar vapor generation. Microchannel provide a novel way to stimulate thin capillary pumping and efficient generation compact devices. On the top of membrane, there layer that absorbs wide-range spectrum converts energy heat. The heat conducted through channels’ walls into liquid menisci ultimately generates vapor. Due capillarity, continuously replenished from bottom side membrane at top. High transfer rates occur region...
