Hydrated granular packings often crack into discrete clusters of grains when dried. Despite its ubiquity, an accurate prediction of cracking remains elusive. Here, we elucidate the previously overlooked role of individual grain shrinkage-a feature common to many materials-in determining crack patterning using both experiments and simulations. By extending classical Griffith crack theory, we obtain a scaling law that quantifies how cluster size depends on the interplay between grain shrinkage, stiffness, and size-applicable to a diverse array of shrinkable granular packings.

Name: Physical review letters
Dry, wet, dense, and dilute granular flows have been previously considered fundamentally different and thus described by distinct, and in many cases incompatible, rheologies. We carry out extensive si...
A major QTL conferring tolerance to radish (Raphanus sativus) root cracking was mapped for the first time and two calcium regulatory genes were identified that positively associated with the cracking ...
We consider zero temperature packings of soft spheres that undergo a jamming to unjamming transition as a function of packing fraction. We compare differences in the structure, as measured from the co...
The surface area (SA) theory proposes that resting metabolic rate (RMR) scales with body mass, which parallels the exchange SA of organisms, and that a species with a larger scaling exponent of exchan...
Pyrolysis combined to either thermal cracking or catalytic cracking of municipal solid waste was performed in a laboratory-scale facility consisting of a fixed-bed reactor followed by a tubular cracki...
Inserting nasal self-packings is a secure method leaving patients more self-confident. We provide a video on https://www.youtube.com/watch?v=LaioLYfSJ-E demonstrating how to use nasal self...
This study uses a drug called dasatinib to produce an anti-cancer effect called large granular lymphocyte cellular expansion. Large granular lymphocytes are blood cells known as natural ki...
The aim of the study is to evaluate the effectiveness of olive oil in the prevention of nipple cracking, nipple pain and ascension maternal satisfaction in lactating women. It's a prospect...
This study is to determine whether scaling and root planing (SRP) followed by photodynamic disinfection results in improved outcomes that persist over time in adults with chronic periodont...
Primary Objective: To identify changes in systemic markers of inflammation following periodontal treatment, comparing two standard treatment modalities (hands scaling and ultrasonic scali...
White blood cells. These include granular leukocytes (BASOPHILS; EOSINOPHILS; and NEUTROPHILS) as well as non-granular leukocytes (LYMPHOCYTES and MONOCYTES).
Designation for several severe forms of ichthyosis, present at birth, that are characterized by hyperkeratotic scaling. Infants may be born encased in a collodion membrane which begins shedding within 24 hours. This is followed in about two weeks by persistent generalized scaling. The forms include bullous (HYPERKERATOSIS, EPIDERMOLYTIC), non-bullous (ICHTHYOSIS, LAMELLAR), wet type, and dry type.
A spectrum of disorders characterized by clonal expansions of the peripheral blood LYMPHOCYTE populations known as large granular lymphocytes which contain abundant cytoplasm and azurophilic granules. Subtypes develop from either CD3-negative NATURAL KILLER CELLS or CD3-positive T-CELLS. The clinical course of both subtypes can vary from spontaneous regression to progressive, malignant disease.
A poisonous dipyridilium compound used as contact herbicide. Contact with concentrated solutions causes irritation of the skin, cracking and shedding of the nails, and delayed healing of cuts and wounds.
A complex of cells consisting of juxtaglomerular cells, extraglomerular mesangium lacis cells, the macula densa of the distal convoluted tubule, and granular epithelial peripolar cells. Juxtaglomerular cells are modified SMOOTH MUSCLE CELLS found in the walls of afferent glomerular arterioles and sometimes the efferent arterioles. Extraglomerular mesangium lacis cells are located in the angle between the afferent and efferent glomerular arterioles. Granular epithelial peripolar cells are located at the angle of reflection of the parietal to visceral angle of the renal corpuscle.
A diagnostic test is any kind of medical test performed to aid in the diagnosis or detection of disease. For example: to diagnose diseases to measure the progress or recovery from disease to confirm that a person is free from disease Clin...
