Evaluating Syrphid Fly Predation on Aphids Under Controlled and Field Conditions in High Tunnels: A Comparative Study With Lacewings

Journal of Applied Entomology, EarlyView.
ABSTRACT Biological control in high tunnel systems can be optimised by matching predator species to seasonal environmental conditions. We evaluated the predatory efficacy of syrphid flies (Toxomerus marginatus (Say), Eupeodes americanus (Fabricius)) and lacewings (Chrysoperla carnea (Stephens), Chrysoperla rufilabris (Burmeister)) across laboratory ...

The 'tumble' departure mode in weightshift-controlled [PDF]

, 2003
The cost of private or recreational flying is high for most conventional aircraft types. During the last 25 years, however, an alternative has become available in the form of the microlight aircraft.

The helium content of globular clusters: NGC6121 (M4)

, 2012
He has been proposed as a key element to interpret the observed multiple MS, SGB, and RGB, as well as the complex horizontal branch (HB) morphology. Stars belonging to the bluer part of the HB, are thought to be more He rich (\Delta Y=0.03 or more) and ...

A Selfless Integrator or a Selfish Quasi‐Professional? Relational Tactics for Organizational Professionals’ Durable Influence

Journal of Management Studies, EarlyView.
Abstract Our study works towards a ‘sociology of organizational professionals’ by elucidating how they navigate domains dominated by occupational professionals. It shows that relational tactics impact whether organizational professionals remain limited to a periphery, become subservient to occupational professionals, or achieve durable roles.

The cosmological Lithium problem outside the Galaxy: the Sagittarius globular cluster M54

, 2014
The cosmological Li problem is the observed discrepancy between Li abundance, A(Li), measured in Galactic dwarf, old and metal-poor stars (traditionally assumed to be equal to the initial value A(Li)_0), and that predicted by standard Big Bang ...

Modelling the chemical evolution of the Galaxy halo [PDF]

, 2013
We study the chemical evolution and formation of the Galactic halo through the analysis of its stellar metallicity distribution function and some key elemental abundance patterns.

Turnout and Invalid Voting in Brazilian Municipal Elections: A Runoff Voting System Tale

Scottish Journal of Political Economy, EarlyView.
ABSTRACT This paper assesses the impact of Brazil's hybrid mayoral voting system on voters' choices and examines the shift in blank, null, and turnout between the first and second rounds. Using fixed‐effects and RDD techniques over 5570 municipalities between 2000 and 2020, this study shows that runoff voting generates more abstention and invalid ...

A pulsational approach to the luminosity of Horizontal Branch stellar structures

, 1998
We discuss an alternative approach to constrain the absolute bolometric luminosity of Zero Age Horizontal Branch structures by using the observational pulsational properties of ab type RR Lyrae stars and theoretical expectations concerning both the ...

The cardiac pacemakers: A paradigm of robustness in evolutionary biology

The Journal of Physiology, EarlyView.
Abstract figure legend Functional networks in living systems are formed by many thousands of gene products. In association with those networks, several genes (four in this diagram) may be sufficient, each on its own, to ensure that the function occurs. Any one of these may be removed or blocked while leaving the others to continue functioning.

Terzan 8: a Sagittarius-flavoured globular cluster

, 2013
Massive globular clusters (GCs) contain at least two generations of stars with slightly different ages and clearly distinct light elements abundances. The Na-O anticorrelation is the best studied chemical signature of multiple stellar generations.
