Oral Health in Alzheimer's Disease: A Life‐Course Perspective on Clinical Management and Caregiver Support

Special Care in Dentistry, Volume 46, Issue 3, May/June 2026.
ABSTRACT Aim: To synthesize current evidence on oral health conditions in individuals with AD and to discuss stage‐specific dental management strategies, including caregiver involvement, from a life‐course perspective. Methods: A comprehensive literature search was conducted in PubMed/MEDLINE, Scopus, Scielo, and Web of Science using MeSH and free‐text

Experimental investigation of the unclogging process of propped fractures with dynamic stimulation: influence of the proppant and of the dynamic signal

Open Geomechanics
Dynamic excitation of reservoir systems trapping hydrocarbons is a potentially promising solution for increasing the production. At the laboratory scale, it was found that a dynamic vibration of the fluid pressure could induce an increase in ...

Complex Fluids and Hydraulic Fracturing [PDF]

, 2016
Nearly 70 years old, hydraulic fracturing is a core technique for stimulating hydrocarbon production in a majority of oil and gas reservoirs. Complex fluids are implemented in nearly every step of the fracturing process, most significantly to generate ...

Characteristics of Seismic Energy Rate Functions of Shallow Tremors

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract We investigated the energy rate functions of shallow tremors southeast of the Kii Peninsula in the Nankai subduction zone. Unimodal functions (triangle or bell‐shaped) explain the characteristics of small (<104 J) shallow tremors. As the seismic radiated energy increases, the energy rate functions become more complex and are better ...

Experimental study on particle migration in propped fractures of coal seam under true triaxial stress

Meitan xuebao
During the production of deep coalbed methane (CBM) after fracturing, the output of coal fines and proppants is prone to occur, leading to a decline in well productivity.

Experimental study on dynamic evolution characteristics of permeability in shale fracturing zones under creep effects

Youqicang pingjia yu kaifa
During shale hydraulic fracturing, strain evolution exacerbates physical damage, leading to differentiated permeability changes across reservoir regions.

A new impulse-stage sand fracturing technology and its pilot application in the western Sichuan Basin

Natural Gas Industry B, 2015
A better placement of proppants has been always the goal pursued in sand fracturing in order to get longer effective fractures and higher flow conductivity. However, it is always difficult to achieve satisfactory effects by conventional processes. On the
