The objective of this study was to investigate the effect of the pattern of concentrate-rich feeding on subacute ruminal acidosis (SARA), its severity, and the corresponding changes in VFA concentration. Eight rumen-cannulated Holstein cows were assigned to a 2 × 2 crossover design with 2 SARA challenge models and 2 experimental runs ( = 8 per treatment). Each run lasted for 40 d, consisting of...

BACKGROUND: Although lentiviral vectors have been widely used for in vitro and in vivo gene therapy researches, there have been few studies systematically examining various conditions that may affect the determination of the number of viable vector particles in a vector preparation and the use of Multiplicity of Infection (MOI) as a parameter for the prediction of gene transfer events. METHODS:...

from the Independent Multidisciplinary Science Team on the forestry project that we just completed. The report contains 19 specific recommendations. Most are directed to the Oregon Department of Forestry (ODF), but there are also recommendations for Oregon Department of Fish and Wildlife (ODFW) and the Forest Research Laboratory (FRL). This report focuses on topics involving the management of (...

This paper presents an investigation into the fire resistance of external light gauge steel framed (LSF) walls clad with autoclaved aerated concrete (AAC) panels exposed to on side. Past research has been limited internal LSF gypsum plasterboard both sides. A series experimental studies including thermal material property tests, a full-scale (3 m × 3 m) ambient capacity test wall and standard t...

Light-gauge steel-framed (LSF) walls are being adopted by the Algerian construction industry as a new alternative to traditional infilled frames due advantages they provide. The strength-to-weight ratio of Cold Formed Section (CFS) leads lighter structures and decrease in building cost. However, case fire, high shape factor combined with loss material properties unprotected, slender CFS can res...

A new tunable electro-optical and thermal-optical modulator based on a liquid crystal (LC) filled side hole fiber (SHF) in ring laser (FRL) system has been proposed experimentally demonstrated. The LC is penetrated into the air of SHF, refractive index (RI) will be altered when an external electrical field or temperature difference applied due to effects electro-optic effects. SHF used as both ...
