The growth rate of cosmic structures in the local Universe with the ALFALFA survey [PDF]
We investigate the growth rate of structures in the local Universe. For this, we use as a cosmological tracer the HI line extra-galactic sources from the Arecibo Legacy Fast ALFA (ALFALFA) survey to obtain a measurement of the normalized growth rate parameter, $f \sigma_{8}$, considered a powerful tool to constrain alternative models of gravity.

This study was conducted to evaluate the effect of adding fermented natural lactic acid bacteria (PFJ) obtained from different sources and some lactic acid bacteria inoculants to alfalfa (Medicago sativa L.) silage on fermentation, in vitro organic ...

The ALFALFA-SDSS Galaxy Catalog [PDF]
We present an HI-optical catalog of ~ 30,000 galaxies based on the 100% complete Arecibo Legacy Fast Arecibo L-band Feed Array (ALFALFA) survey combined with data from the Sloan Digital Sky Survey (SDSS). Our goal is to facilitate public use of the completed ALFALFA catalog by providing carefully determined matches to SDSS counterparts, including ...

The Arecibo Legacy Fast ALFA Survey: I. Science Goals, Survey Design and Strategy [PDF]
The recently initiated Arecibo Legacy Fast ALFA (ALFALFA) survey aims to map 7000 square degrees of the high galactic latitude sky visible from Arecibo, providing a HI line spectral database covering the redshift range between -1600 km/s and 18,000 km/s with 5 km/s resolution.

ALFALFA: an Exploration of the z=0 HI Universe [PDF]
The Arecibo Legacy Fast ALFA (ALFALFA) Survey is a program aimed at obtaining a census of HI-bearing objects over a cosmologically significant volume of the local Universe. It will cover 7074 square degrees of the high latitude sky accessible with the Arecibo 305m telescope, using the 7-beam feed L-band feed array (ALFA).

A Generalist, Automated ALFALFA Baryonic Tully-Fisher Relation [PDF]
The Baryonic Tully-Fisher Relation (BTFR) has applications in galaxy evolution as a testbed for the galaxy-halo connection and in observational cosmology as a redshift-independent secondary distance indicator. We use the 31,000+ galaxy ALFALFA sample -- which provides redshifts, velocity widths, and HI content for a large number of gas-bearing galaxies

Effect of Alfalfa Meal, Alfalfa Leaves, Alfalfa Stems and Fresh Alfalfa on Chick Growth
Abstract Studies by various investigators, Cooney et al. (1948); Draper et al. (1948); Lepkovsky et al. (1949); and Kodras et al. (1951), have shown that there is a relation between the depression of chick growth and the level of alfalfa meal in the rations. Data obtained by Cooney et al. with chicks fed rations containing alfalfa meal and equivalent

Screening of Alfalfa Varieties Resistant to Phytophthora cactorum and Related Resistance Mechanism
Alfalfa is one of the most important legume forages in the world. Root rot caused by soil-borne pathogens severely restricts the production of alfalfa.

Early-type galaxies with neutral hydrogen in the Virgo cluster from the ALFALFA survey [PDF]
We extend our published work on the neutral hydrogen content of early-type galaxies in the Virgo cluster using the catalogue of detected sources from the ALFALFA survey, by showing the 21cm spectra of all the detected galaxies and discussing a deeper analysis of the ALFALFA datacubes, searching for lower S/N sources.
