Simultaneous Effect of Collar and Roughness on Reducing and Controlling the Local Scour around Bridge Abutment

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2017
Investigation of local scour around hydraulic structures particularly bridges is of crucial importance in river engineering. Bridge destruction mostly occurs as a result of scour phenomenon around piers and abutments, not because of structural weaknesses.

Subperiosteal peri‐implant augmented layer to correct bone dehiscence at immediate implant placement

Clinical Advances in Periodontics, EarlyView.
Abstract Background The purpose of the present case report is to describe the potential of the subperiosteal peri‐implant augmented layer (SPAL) technique in peri‐implant bone dehiscence (PIBD) correction at immediate implant placement (IIP). Methods This case report describes the application of the SPAL technique in two patients undergoing IIP at ...

Comparison of Stress Distribution on a Straight and Angulated Abutment of Different Internal Hex Connections – Finite Element Analysis

Indian Journal of Dental Sciences
Context: Various internal connections of implant abutments show different stress distributions. To improve this, a newer Morse taper connection is introduced. This connection aims to harmonize stress distribution between the abutment and implant fixture,

Post‐LECA Origin and Diversification of an Axonemal Outer Arm Dynein Motor

Cytoskeleton, EarlyView.
ABSTRACT Dyneins were present in the last eukaryotic common ancestor (LECA) and play key roles in eukaryotic biology. Axonemal dyneins form the inner and outer arms that power ciliary beating, and it has long been recognized that outer arms in some organisms contain two different heavy chain motors, whereas those from other species contain a third unit

Effects of abutment-implant combinations with different elastic moduli on osteogenic performance

工程科学学报, 2019
Many factors affect the success of dental implant surgery, such as surgical trauma, excessive chewing pressure, material performance mismatch, and improper abutment-implant connection.

The Benjamin–Ono Equation in the Zero‐Dispersion Limit for Rational Initial Data: Generation of Dispersive Shock Waves

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT The leading‐order asymptotic behavior of the solution of the Cauchy initial‐value problem for the Benjamin–Ono equation in L2(R)$L^2(\mathbb {R})$ is obtained explicitly for generic rational initial data u0$u_0$. An explicit asymptotic wave profile uZD(t,x;ε)$u^\mathrm{ZD}(t,x;\epsilon)$ is given, in terms of the branches of the multivalued ...

Advancing mine pillar design: Evaluating traditional methods and integrating AI for enhanced stability of pillars in the Great Dyke, Zimbabwe

Deep Underground Science and Engineering, EarlyView.
B1 is bord width 1, B2 is bord width 2, L is the pillar length, W is the pillar width, red color and letter A represent the pillars, and white color and number 1 represent excavated areas. Pstress is the average pillar stress; σv is the vertical component of the virgin stress, MPa; and e is the areal extraction ratio. e = B o B o + B P ${\rm{e}}=\frac{{

Mechanism and disaster control new technology of strong ground pressure manifestation in ultra‐large mining face

Deep Underground Science and Engineering, EarlyView.
In response to the problem of strong mining pressure manifestation along the goaf roadway in a thick coal seam mining area, this study uses a new type of combined blasting roof cutting technology to effectively control the manifestation and deformation of mining pressure along the goaf roadway.

Development and preclinical evaluation of a hybrid stereoelectroencephalographic–laser depth electrode for magnetic resonance imaging‐guided interstitial thermal therapy in drug‐resistant epilepsy

Epilepsia, EarlyView.
Abstract Objective This study was undertaken to design and validate a hybrid depth electrode combining stereoelectroencephalographic (sEEG) recording and magnetic resonance‐guided laser interstitial thermal therapy (MRgLITT) under real‐time magnetic resonance thermometry, to streamline the transition from invasive localization to focal ablation in ...
