Soil Nutrient Availability, Plant Nutrient Uptake, and Wild Blueberry (Vaccinium angustifolium Ait.) Yield in Response to N-Viro Biosolids and Irrigation Applications

open access: yesApplied and Environmental Soil Science, 2012
We compared the impact of surface broadcasted N-Viro biosolids and inorganic fertilizer (16.5% Ammonium sulphate, 34.5% Diammonium phosphate, 4.5% Potash, and 44.5% s and/or clay filler) applications on soil properties and nutrients, leaf nutrient ...

Turaev–Viro invariants and cabling operations

open access: yesInternational Journal of Mathematics, 2023
In this paper, we study the variation of the Turaev–Viro invariants for [Formula: see text]-manifolds with toroidal boundary under the operation of attaching a [Formula: see text]-cable space. We apply our results to a conjecture of Chen and Yang which relates the asymptotics of the Turaev–Viro invariants to the simplicial volume of a compact oriented

Holonomy observables in Ponzano-Regge type state sum models [PDF]

open access: yes, 2011
We study observables on group elements in the Ponzano-Regge model. We show that these observables have a natural interpretation in terms of Feynman diagrams on a sphere and contrast them to the well studied observables on the spin labels.

Lähdekielen vaikutus ja kielitaitotasot: paikallissijojen kehitys oppijansuomessa

open access: yesLähivõrdlusi, 2013
Artikkelissa tarkastelemme, millaista funktioltaan konkreettisten ja abstraktien paikallissijojen käyttö on oppijansuomessa. Tutkimuksen lähtökohtana on Eurooppalainen viitekehys: kielten oppiminen, opettaminen, arviointi (2003, tästä lähtien EVK) ja sen

Aged xCT-Deficient Mice Are Less Susceptible for Lactacystin-, but Not 1-Methyl-4-Phenyl-1,2,3,6- Tetrahydropyridine-, Induced Degeneration of the Nigrostriatal Pathway

open access: yesFrontiers in Cellular Neuroscience, 2021
The astrocytic cystine/glutamate antiporter system xc– (with xCT as the specific subunit) imports cystine in exchange for glutamate and has been shown to interact with multiple pathways in the brain that are dysregulated in age-related neurological ...

Higher-order finite type invariants of classical and virtual knots and unknotting operations

open access: yes, 2020
Vassiliev introduced filtered invariants of knots using an unknotting operation, called crossing changes. Goussarov, Polyak, and Viro introduced other filtered invariants of virtual knots, which order is called GPV-order, using an unknotting operation ...

BTZ Black Hole Entropy from Ponzano-Regge Gravity [PDF]

open access: yes, 1998
The entropy of the BTZ black hole is computed in the Ponzano-Regge formulation of three-dimensional lattice gravity. It is seen that the correct semi-classical behaviour of entropy is reproduced by states that correspond to all possible triangulations of

Immune recovery in acute and chronic HIV infection and the impact of thymic stromal lymphopoietin

open access: yesBMC Infectious Diseases, 2016
Background Symptomatic primary HIV infection is associated with an adverse prognosis, and immediate initiation of combination antiretroviral therapy (cART) is recommended. However, little is known about immunological predictors of immune recovery. Thymic
