PHYSICAL QUALITY OF SANDY SOIL UNDER MANAGEMENT SYSTEMS AND CHISELING OF SUGARCANE RATOONS

open access: yesRevista de Agricultura Neotropical
The adoption of soil management practices in sugarcane production areas must ensure both economic and environmental sustainability. This study evaluated the effects of different management systems (conventional tillage – CT, reduced tillage – RT, and no-

From sagittal to sprawled: Clavicular co‐option and the evolution of forelimb mechanics in talpines

open access: yesJournal of Anatomy, EarlyView.
Forelimb posture in Eulipotyphla divides into sagittal and sprawled groups with distinct scapular and clavicular orientations. First true rib strength scales with body mass, reflecting vertical ground reaction forces, whereas clavicular strength reflects differences in medially directed forces on the pectoral girdle, especially pronounced in highly ...

Heterodonty in the teeth of the turiasaurian sauropod from Angeac‐Charente (Early Cretaceous, southwestern France): Comparison of anatomical and geometric morphometric approaches

open access: yesJournal of Anatomy, EarlyView.
Turiasaurian teeth from Angeac‐Charente exhibit five dental morphotypes and reveal clear heterodonty and anteroposterior size gradient. Qualitative comparative anatomy quickly and efficiently identifies morphotypes, while 3D geometric morphometrics combined with machine learning refine ambiguous cases, demonstrating that qualitative and quantitative ...

Maize Yield and Soil Penetration Resistance in Different Soil Tillage and Cover Crop Systems [PDF]

open access: yesBrazilian Archives of Biology and Technology
No-tillage (NT) is a conservation practice adopted by 60% of the Brazilian farmers. Due to unsuitable management, compaction problem reported in soils under NT has increased.

Photochemical effects of Mars‐like UV irradiation on carboxylic acids in carbonaceous chondrites and expectations for abiotic background organics on Mars

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract In the search for life on Mars, understanding the origin of preserved organics is critical. Expected sources include exogenous delivery, endogenous synthesis, and potentially life. Environmental processing by ultraviolet (UV) irradiation can alter these organics, obscuring hallmarks of their origin. To deconvolve these effects, we conducted an

Into the Bermuda Triangle: How Prime Ministers Fall

open access: yesIPPR Progressive Review, EarlyView.
ABSTRACT Eleven years after David Cameron promised ‘stability and strong government’; nine years after Theresa May pledged ‘strong and stable leadership’; and two years after Keir Starmer vowed to ‘stop the chaos’, the UK has its seventh prime minister in a decade.

Physical properties of an Alfisol and no-till soybean yield

open access: yesRevista Brasileira de Ciência do Solo, 2012
It is known that any kind of soil management causes changes in the soil physical characteristics and can affect agricultural yield. The purpose of this study was to evaluate soil properties of an Alfisol and soybean yield under different management ...

Three‐Dimensional Effects of Two Minimally Invasive Surgically Assisted Rapid Palatal Expansion Techniques

open access: yesOrthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objective This study evaluated, in three dimensions, the skeletal effects of two minimally invasive bone‐anchored techniques for surgically assisted palatal expansion, with and without pterygomaxillary disjunction (PD) and nasal septum disinsertion (NSD). Materials and Methods Thirty‐nine patients were retrospectively selected from two centres

Critical limits of soil penetration resistance in a rhodic Eutrudox

open access: yesRevista Brasileira de Ciência do Solo, 2014
Soil penetration resistance is an important indicator of soil physical quality and the critical limit of 2 MPa has been widely used to characterize the soil physical quality, in both no-tillage and conventional systems.
