Hybridogenesis in Rana esculenta: C-band karyotypes of Rana ridibunda, Rana lessonae and Rana esculenta

open access: yesJournal of Zoological Systematics and Evolutionary Research, 2009
Summary C-banding patterns have been studied in R. ridibunda, R. lessonae and R. esculenta from Austrian waterfrog populations of R. lessonae+R. esculenta, and of pure R. ridibunda populations respectively. A conspiciuous heterochromatic marker band in chromosome no. 11, which is homozygously present in R.

Influence of Nitrogen Ion Implantation on the Structural, Morphological and Optical Properties of Al‐Doped ZnO [AZO] Thin Films for High‐Performance Optoelectronic Applications

open access: yesAdvanced Physics Research, EarlyView.
This work reports near‐surface nitrogen ion implantation in Al‐doped ZnO thin films deposited by RF magnetron sputtering and examines post‐implantation effects at room temperature. Structural, morphological, optical, and electrical modifications are analyzed.

Rectangularity and paramonotonicity of maximally monotone operators [PDF]

open access: yes, 2012
Maximally monotone operators play a key role in modern optimization and variational analysis. Two useful subclasses are rectangular (also known as star monotone) and paramonotone operators, which were introduced by Brezis and Haraux, and by Censor, Iusem

Oldest well‐preserved euprimate petrosal, from the early Eocene of India (Vastan Lignite Mine, Gujarat)

open access: yesThe Anatomical Record, EarlyView.
Abstract An exquisitely preserved, isolated partial petrosal with associated fragmentary stapes is described from the Vastan Lignite Mine (Gujarat, India), dated to the early Eocene (~54.5 Ma). Several anatomical traits (e.g., large petrosal plate; posterolateral entry of the internal carotid artery to the tympanic cavity; bony tubes surrounding the ...

RESPIRATION OF HOMOGENIZED EMBRYOS: RANA PIPIENS AND RANA PIPIENS ♀ x RANA SYLVATICA ♂

open access: yesThe Biological Bulletin, 1957
1. The respiration of phosphate-buffered cell-free homogenates made from R. pipiens embryos increases exponentially with the age of the embryos up until the time at which they are in the tailbud stage, after which the rate declines.2. Addition of 0.2% sodium deoxycholate elevates the respiration of homogenized embryos at any pre-tailbud stage to that ...

Graphene Terahertz Plasmon Oscillators

open access: yes, 2007
In this paper we propose and discuss coherent terahertz sources based on charge density wave (plasmon) amplification in two dimensional graphene. The coupling of the plasmons to interband electron-hole transitions in population inverted graphene layers ...

Green Is the New Gold: Redefining Opulent Lifestyle Through Organic Food Purchases

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Prior studies based on the Theory of Planned Behavior mostly examined the effects of health and environmental concerns on organic food consumption; however, few addressed the paradoxical relationships in the context of opulent or symbolic decorum.
