Beam Imaging and Luminosity Calibration

, 2019
We discuss a method to reconstruct two-dimensional proton bunch densities using vertex distributions accumulated during LHC beam-beam scans. The $x$-$y$ correlations in the beam shapes are studied and an alternative luminosity calibration technique is ...

Ab initio simulations of accretion disks instability [PDF]

, 2003
We show that accretion disks, both in the subcritical and supercritical accretion rate regime, may exhibit significant amplitude luminosity oscillations.

Growth and flowering of carnation cultivated in different pot colors and protected environments

Notulae Botanicae Horti Agrobotanici Cluj-Napoca
The Dianthus caryophyllus L. occupies the second position of the best sold cut flowers after rose. The choice of the environment and the cultivation container is crucial for flower production because, besides permitting higher temperature, light, and ...

The influence of side-curtain color on broiler chick behavior

Brazilian Journal of Poultry Science, 2013
Brazilian poultry production is prospering, and negative-pressure broiler houses are increasingly used to improve environmental control. One important issue is the color of the side curtains used in such houses due to the influence of colors on broiler ...

The host galaxies of low luminosity quasars at high redshift

, 2005
We present VLT/ISAAC near-infrared imaging of the host galaxies of 15 low luminosity quasars at 1 < z < 2. This work complements our studies to trace the cosmological evolution of the host galaxies of high luminosity quasars.

Productivity and morphological characteristics of buffel grass intercropped with butterfly pea under shade conditions

Bioscience Journal, 2017
Forage production in the Brazilian semiarid region can be enhanced by irrigation and shading to maximize water use. We evaluated the productivity and morphological characteristics of buffel grass (Cenchrus ciliaris) intercropped with butterfly pea ...

The Luminosity Function of Galaxies as modeled by a left truncated beta distribution

, 2014
A first new luminosity functions of galaxies can be built starting from a left truncated beta probability density function, which is characterized by four parameters.

Crescimento in vitro e aclimatização de Cattleya loddigesii Lindley (Orchidaceae) com carvão ativado sob dois espectros luminosos In vitro growth and acclimatization of Cattleya loddigesii Lindley (Orchidaceae) with actived charcoal in two light spectra

Ciência Rural, 2012
O objetivo deste estudo foi avaliar a adição de concentrações de carvão ativado em meio de cultura ½ MS (com metade da concentração dos macronutrientes) sob dois espectros luminosos para a obtenção de plântulas in vitro de Cattleya loddigesii.

Simulations of Dust in Interacting Galaxies

, 2004
A new Monte-Carlo radiative-transfer code, Sunrise, is used to study the effects of dust in N-body/hydrodynamic simulations of interacting galaxies. Dust has a profound effect on the appearance of the simulated galaxies.
