Buccal Alveolar Bone changes and upper first molar displacement after maxillary expansion with RME, Ni-Ti leaf springs expander and Tooth- Bone-borne Expander. A CBCT based analysis [PDF]

open access: green, 2023
Aim: To evaluate the buccal alveolar bone changes and the upper first molar displacement in subjects treated with conventional rapid maxillary expansion (RME), Ni-Ti leaf springs expander (Leaf Expander) and Tooth-Bone-borne Expander (Hybrid Expander ...

Coping with stress: mechanics of the expanding leaf [PDF]

open access: hybridJournal of Experimental Botany, 2016
The precise control of physical properties of growing tissues is crucial for plant morphogenesis. Sahaf and Sharon (pages 5509–5515 in this issue) examined the mechanics of the expanding leaf and showed that plant tissues respond to stress by changing their mechanical properties.

Influence of Cajuput Leaf Residue on the Properties of Lightweight Expanded Clay Aggregate [PDF]

open access: goldDiscover Materials
Abstract This study investigates the utilization of cajuput leaf residue as an additive in the production of Lightweight Expanded Clay Aggregates (LECA). The solid cajuput residue, a by-product of cajuput oil extraction, was mixed with clay in varying ratios (0%, 10%, 20%, 30%, and 40% by weight, denoted as 0%RW, 10%RW, 20%RW, 30%RW and 40%RW ...

Tender leaf and fully-expanded leaf exhibited distinct cuticle structure and wax lipid composition in Camellia sinensis cv Fuyun 6 [PDF]

open access: goldScientific Reports, 2018
AbstractThe goal of the present study was to compare the structural and compositional differences of cuticle between tender leaf and fully-expanded leaf in Camellia sinensis, and provide metabolic base for the further characterization of wax biosynthesis in this economically important crop species.

Expanding clinical laboratory tobacco product evaluation methods to loose-leaf tobacco vaporizers [PDF]

open access: greenDrug and Alcohol Dependence, 2016
Novel tobacco products entering the US market include electronic cigarettes (ECIGs) and products advertised to "heat, not burn" tobacco. There is a growing literature regarding the acute effects of ECIGs. Less is known about "heat, not burn" products.

Expanding our understanding of leaf functional syndromes in savanna systems: the role of plant growth form [PDF]

open access: greenOecologia, 2017
The assessment of leaf strategies has been a common theme in ecology, especially where multiple sources of environmental constraints (fire, seasonal drought, nutrient-poor soils) impose a strong selection pressure towards leaf functional diversity, leading to inevitable tradeoffs among leaf traits, and ultimately to niche segregation among coexisting ...

Le Leaf Expander ® : alternative au disjoncteur classique dans l'expansion transversale maxillaire ?

open access: green
Maxillary endognathia is a skeletal anomaly of the maxilla in the transverse dimension, characterized by a deficiency. Several etiologies of this malocclusion have been described, including genetic, functional, environmental, pathological, and hormonal ...

Expanding sugar beet's utility: genetic insights into leaf protein valorisation

open access: green
Modern plant breeding has largely focused on improving crops for specific harvest organs such as fruits, seeds, or roots, while overlooking the substantial residual biomass generated during cultivation. These residues, often used for low-value purposes, contain valuable biochemicals (proteins, fibers, lipids, and bioactive compounds) that are suitable ...

Effects On Palatal Surface Area In Mixed Dentition Patients Treated With Leaf Expander And Rapid Palatal Expander, Compared To Untreated Subjects: A Randomised Clinical Trial.

open access: greenEuropean journal of paediatric dentistry
Aim To evaluate palatal surface effects induced by LE and RPE, alongside spontaneous changes in an untreated group, and to compare differences in canine and molar inclination among the three groups. Materials and Methods This randomised clinical trial aimed to compare digital models pre- and post-treatment over 12 months in patients receiving tooth ...

Diazepam, the modulator of GABAA receptors, alters the leaf-folding and expanding speed of Mimosa pudica [PDF]

open access: green
Abstract Mimosa pudica L. closes leaves in response to various stimuli. This curious reflex, called seismonastic movement, is said to be advantageous for their survival from predatory insects but is a trade-off between efficient energy acquisition.
