Pulling the tablecloth out from under essential metabolism
Pulling the tablecloth out essential metabolism
2017/7/24
Because plants can’t get up and run away, they’ve had to be clever instead. They are the chemists of the living world, producing hundreds of thousands of small molecules that they use as sunscreens, t...
In vitro Screening of Essential Oil Active Compounds for Manipulation of Rumen Fermentation and Methane Mitigation
Essential Oil Active Compounds Methane Production Volatile Fatty Acid Production
2016/7/27
The objective of this study was to investigate the effects of 11 active compounds of essential oils (ACEO) on rumen fermentation characteristics and methane production. Two trials were conducted. In t...

We study the local geometry of irreducible parabolic geometries admitting
strongly essential
ows; these are
ows by local automorphisms with higher-order xed
points. We prove several new rigidit...
ESSENTIAL KILLING FIELDS OF PARABOLIC GEOMETRIES: PROJECTIVE AND CONFORMAL STRUCTURES
PARABOLIC GEOMETRIES PROJECTIVE
2015/10/14
We use the general theory developed in our article [1]
in the setting of parabolic geometries to reprove known results on
special in nitesimal automorphisms of projective and conformal
geometries.
We study vector elds generating a local
ow by automorphisms of a parabolic geometry with higher order xed points.
We develop general tools extending the techniques of [1], [2], and
[3], and we a...
THE ESSENTIAL DIMENSION OF A g-DIMENSIONAL COMPLEX ABELIAN VARIETY IS 2g
ESSENTIAL DIMENSION COMPLEX ABELIAN VARIETY IS 2g

We compute the Buhler-Reichstein essential dimension of a complex abelian variety using Kummer theory.
Essential dimension is a numerical invariant of an algebraic
group G introduced by J. Buhler and the second author to study the
complexity of G-torsors over a eld K. It has since been studied by se...
We prove that the essential dimension of the spinor group
Spinn grows exponentially with n and use this result to show that quadratic forms with trivial discriminant and Hasse-Witt invariant are more...
ESSENTIAL DIMENSION OF MODULI OF CURVES AND OTHER ALGEBRAIC STACKS (WITH AN APPENDIX BY NAJMUDDIN FAKHRUDDIN)
ESSENTIAL DIMENSION OTHER ALGEBRAIC STACKS
2015/9/29
In this paper we consider questions of the following type.
Let k be a base eld and K=k be a eld extension. Given a geometric
object X over a eld K (e.g. a smooth curve of genus g) what is the
le...

ESSENTIAL DIMENSION OVER NUMBER FIELDS
2015/9/29
We affirmatively answer a conjecture in the preprint “Essential
dimension and algebraic stacks,” proving that the essential dimension of an
abelian variety over a number field is inʂ...

Post-tsunami field investigations are an essential component for improving our understanding of tsunamis and in developing the tools and programs necessary to mitigate their effects. A destructive tsu...
Impact of cadmium on the level of hepatic metallothioneins, essential elements, and selected enzymes in the experimental rat model

2015/7/2
The response of different strains of laboratory rats (Rattus norvegicus L.) on both acute (via intraperitoneal injection) and chronic (via drinking water and/or diet) cadmium intoxication was investig...
Biochar can be used to capture essential nutrients from dairy wastewater and improve soil physico-chemical properties
Biochar nutritional dairy products waste water biomass agriculture nutrients soil productivity
2015/1/6
Recently, the potential for biochar use to recapture excess nutrients from dairy wastewater has been a focus of a growing number of studies. It is suggested that biochar produced from locally availabl...
