Relationships between base saturation, effective base saturation and soil pH as the references for the development and verification of criteria for international soil classification

open access: yesGeoderma
Base saturation (BS) and effective base saturation (BSe) are widely used soil characteristics, commonly involved in the criteria of soil classification, including the World Reference Base for Soil Resources (WRB) system.

Relationships between soil pH and base saturation – conclusions for Polish and international soil classifications

open access: yesSoil Science Annual, 2018
Taking into account the fact that (a) measurement of the cation exchange capacity and base saturation is practically unavailable in the field, that formally makes impossible the reliable field classification of many soils, (b) base saturation is measured

The Ebers-Moll model for magnetic bipolar transistors [PDF]

open access: yes, 2004
The equivalent electrical circuit of the Ebers-Moll type is introduced for magnetic bipolar transistors. In addition to conventional diodes and current sources, the new circuit comprises two novel elements due to spin-charge coupling.

Function‐driven design of a surrogate interleukin‐2 receptor ligand

open access: yesFEBS Letters, EarlyView.
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

Alterações químicas temporais nas faixas de adubação e entrelinhas do pomar, nutrição e produção de laranja após calagem superficial Yield and temporal chemical changes in fertilizer bands and inter-rows of an orange orchard after surface liming

open access: yesRevista Brasileira de Ciência do Solo, 2008
Apesar das diferenças químicas entre as faixas de adubação e entrelinhas de pomares de laranjeiras, o critério para a calagem superficial entre esses dois locais ainda é desconhecido.

Cell wall target fragment discovery using a low‐cost, minimal fragment library

open access: yesFEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Soils classified in the Arboretum Mlyňany, Slovakia

open access: yesFolia Oecologica, 2018
Successful adaptation of introduced trees requires providing appropriate conditions for their growth and life. In this context, our study aim was a soil survey in the Arboretum Mlyňany, on the basis of which the soils could be classified.

Alterações nas propriedades químicas e físicas de um chernossolo com diferentes coberturas vegetais Alterations in the chemical and physical properties of a chernosol under different crop covers

open access: yesRevista Brasileira de Ciência do Solo, 2007
O agrossistema de Itapetinga, Bahia, tem a pecuária como uma das principais atividades econômicas. Sabe-se que a pecuária é uma atividade que causa impactos diretos no solo, no subsolo e na vegetação. Este estudo teve o objetivo de verificar mudanças nas

On sets of graded attribute implications with witnessed non-redundancy

open access: yes, 2015
We study properties of particular non-redundant sets of if-then rules describing dependencies between graded attributes. We introduce notions of saturation and witnessed non-redundancy of sets of graded attribute implications are show that bases of ...

Nanographene‐Based Saturable Absorbers for Ultrafast Fiber Lasers [PDF]

open access: yesJournal of Nanomaterials, 2014
The generation of femtosecond pulse laser in the erbium‐doped fiber laser system is presented by integrating of the nanographene‐based saturable absorbers (SAs). A simplified method of dispersed nanographene‐based SAs side‐polished fiber device with controllable polished length and depth was also developed.
