There have been many rich, naturalistic studies documenting prelinguistic communicative abilities that suggest that the ntegration of alternating eye gaze, vocal behaviors, and nonverbal gestures are indicative of intentional communication (e.g., ates, Camaioni, & Volterra, 1975; Bates, Benigni, Bretherton, Camaioni, & Volterra, 1979; Dore, 1974; Ninio & Bruner, 1978; revarthen & Hubley, 1978)....
________________________________________________________________________________ Abstract The aim of the study was to determine if the breeding potential of 25-month old Bonsmara beef bulls could be predicted from production characteristics. Forty-one Bonsmara bulls were included in an on-farm performance test (also known as the Phase D growth test) for a period of 180 days. At an average age o...
This study was performed in adult male goats in which seasonal variations were abolished by rapid alternations of long days and short days. These treatments have been shown previously to prevent seasonal changes in the hypothalamo-pituitary axis and to maintain testis weight and sperm production at a high level. The experimental groups were exposed for 3 years to an alternation of either a 1 mo...
Effect of inorganic fertilizer on the fish growth and production in polyculture system of Bangladesh
A study was carried out on the optimal dose of inorganic fertilizer used in carp polyculture system over a period of 10 months. Three treatments were assigned: without inorganic fertilizer, with the application of 100 kg/ha/month inorganic fertilizer and 150 kg/ha/month inorganic fertilizer as T1, T2 and T3, respectively. Each treatment had three replications. The selected indigenous carp speci...
-To characterize remodeling of elastic arteries with aging and to investigate its potential mechanisms, matrix metalloproteinase-2 (MMP-2), intracellular adhesive molecule-1 (ICAM-1), transforming growth factor-beta (TGF-beta), and fibronectin protein levels were measured in the aortas of young adult (6 months) and aged (30 months) Fischer 344XBN rats. At 30 versus 6 months, the thickness of th...
In this study, the performance of 300 Changbaishan Black cattle treated for superovulation from June to September was evaluated to determine the optimal conditions and herds for bovine embryo production. Data analysis revealed that cattle treated in July and August had higher numbers of available embryos (NAE), M1 embryos (NM1), and total embryos (NTE), as well as a higher percentage of M1 embr...
We examined whether sleep quality during the night and naps during the day preceding a learning event are related to memory encoding in human infants. Twenty-four 6- and twenty-four 12-month-old infants' natural sleeping behavior was monitored for 24 hr using actigraphy. After the recording period, encoding was assessed using an imitation paradigm. In an initial baseline phase, infants were all...
This report presents evidence that smile production in lO-month-old infants is affected by the presence or absence of an audience for the facial display. The audience effect does not appear to be mediated by emotion. The evidence indicates that the production of facial expressions is at least partly independent of emotion and partly dependent on a social-communicative context from a very early ...
Wood is the main terrestrial biotic reservoir for long-term carbon sequestration(1), and its formation in trees consumes around 15% of anthropogenic carbon dioxide emissions each year(2). However, the seasonal dynamics of woody biomass production cannot be quantified from eddy covariance or satellite observations. As such, our understanding of this key carbon cycle component, and its sensitivit...
Pilot-scale digesters (850 L) were used to quantify CH4 and H2S production when using forage radish cover crops as a co-digestion feedstock in dairy manure-based digesters. During two trials, triplicate mixed digesters were operated in batch mode with manure-only or radish+manure (27% and 13% radish by wet weight in Trial 1 and 2, respectively). Co-digestion increased CH4 production by 11% and ...
