Quasi-periodic stability of normally resonant tori [PDF]

open access: yes, 2007
We study quasi-periodic tori under a normal-internal resonance, possibly with multiple eigenvalues. Two non-degeneracy conditions play a role. The first of these generalizes invertibility of the Floquet matrix and prevents drift of the lower dimensional ...

The effect of using lycopene compared to BHT as antioxidants on the productive performance of laying hens lohmann brown [PDF]

open access: yesمجلة جامعة كركوك للعلوم الزراعية
The experiment was conducted on 112 Lohmann Brown birds in the poultry fields/College of Agriculture/University of Kirkuk, for a period of 70 field days for the period from 10/2/2023 to 11/28/2023, which included 14 days as an introductory period.

The effects of a 4-week mesocycle of barbell back squat or barbell hip thrust strength training upon isolated lumbar extension strength [PDF]

open access: yesPeerJ, 2019
Objectives Common exercises such as the barbell back squat (BBS) and barbell hip thrust (BHT) are perceived to provide a training stimulus to the lumbar extensors.

Multiple Vector Valued Inequalities via the Helicoidal Method

open access: yes, 2016
We develop a new method of proving vector-valued estimates in harmonic analysis, which we like to call "the helicoidal method". As a consequence of it, we are able to give affirmative answers to some questions that have been circulating for some time. In

Hamiltonian analysis of BHT massive gravity

open access: yes, 2011
We study the Hamiltonian structure of the Bergshoeff-Hohm-Townsend (BHT) massive gravity with a cosmological constant. In the space of coupling constants $(\Lambda_0,m^2)$, our canonical analysis reveals the special role of the condition $\Lambda_0/m^2 ...

Assessment of Safety, Effects, and Muscle-Specific Accumulation of Dietary Butylated Hydroxytoluene (BHT) in Paralichthys olivaceus

open access: yesAquaculture Nutrition, 2023
Butylated hydroxytoluene (BHT) is a commonly used antioxidant added to animal/fish feed to limit lipid autoxidation and peroxidation. Although there have been reviews and reports of BHT toxicity in animals, limited information is available with respect ...

Biological fate of butylated hydroxytoluene (BHT): Subcellular distribution of BHT in rat liver.

open access: yesChemical and Pharmaceutical Bulletin, 1978
Biological fate of 14C-labeled butylated hydroxytoluene (14C-BHT) in rat liver was investigated. After a single oral dose of 14C-BHT, the radioactivity was reached a maximum concentration in the liver after 6 hr and in the serum after 6-12 hr. A bulk of radioactivity was found in the supernatant fraction, although the amount of radioactivity and ...

Some interesting features of new massive gravity

open access: yes, 2011
A proof that new massive gravity - the massive 3D gravity model proposed by Bergshoeff, Hohm and Townsend (BHT) - is the only unitary system at the tree level that can be constructed by augmenting planar gravity through the curvature-squared terms, is ...

Fractional Hida Malliavin Derivatives and Series Representations of Fractional Conditional Expectations [PDF]

open access: yes, 2015
We represent fractional conditional expectations of a functional of fractional Brownian motion as a convergent series in L^2 space. When the target random variable is some function of a discrete trajectory of fractional Brownian motion, we obtain a ...

Action and fate of natural and synthetic antioxidants during frying

open access: yesGrasas y Aceites, 2010
The action of antioxidants to delay lipid oxidation in fats and oils is well known although most of the information is related to their effects at room temperature during storage or at the moderate temperatures of the accelerated tests to measure oil ...
