The aim of this study was to determine that the total anthocyanin content (TAC) and antioxidant activity (AOA) in potato flesh with different colours grown in the Czech Republic. Four yellowor white-, six purpleand four red-fleshed varieties were grown in 2009 at two different sites (Valečov – highland, seed potato area at 460 m a.s.l., Přerov nad Labem – lowland, new potatoes area at 178 m a.s...

The question of whether age-of-acquisition (AoA), frequency, and repetition priming effects occur at a common stage or at different stages of processing is addressed. Two single-stage accounts (i.e., cumulative frequency and a neural-network simulation) are considered in regard to their predictions concerning the interactions between AoA and frequency with aging and priming effects. A repetitio...

Age of acquisition (AoA) effects have been used to support the notion of a critical period for first language acquisition. In this study, we examine AoA effects in deaf British Sign Language (BSL) users via a grammaticality judgment task. When English reading performance and nonverbal IQ are factored out, results show that accuracy of grammaticality judgement decreases as AoA increases, until a...

This paper proposes a mobile user location scheme for wideband code-division multiple-access (CDMA) wireless communication systems. To achieve high location accuracy and low cost of the mobile receiver, the location scheme combines the time difference of arrival (TDOA) measurements from the forward link pilot signals with the angle of arrival (AOA) measurement from the reverse link pilot signal...

Autotrophic archaeal and bacterial ammonia-oxidisers (AOA and AOB) drive soil nitrification. Ammonia limitation, mixotrophy, and pH have been suggested as factors providing niche specialisation and differentiation between soil AOA and AOB. However, current data from genomes, cultures, field studies, and microcosms suggest that no single factor discriminates between AOA and AOB. In addition, the...

The author provides an update on the current CME cycle, which began on January 1, 2010, and will end on December 31, 2012. The author also details minor changes to the requirements for Category 1 CME sponsors accredited by the AOA and describes new online CME opportunities. The current article also explains changes regarding the AOA's awarding and recording of specialty CME credit hours for AOA...

Words and pictures with earlier learned labels are processed faster than words and pictures with later learned labels. This age-of-acquisition (AoA) effect has been extensively investigated in many different types of tasks. This article provides a review of these studies including picture naming, word naming, speeded word naming, word pronunciation durations, lexical decisions, eye fixation tim...

Morrison and Ellis (1995) claim that most evidence of frequency e€ ects in word recognition is not genuine but an artefact of the age at which the words have been acquired. The ® nding that age of acquisition (AOA) has a reliable independent e€ ect on word naming is replicated for the Dutch language. However, it is also shown that the e€ ect of word frequency remains reliable with AOA controlle...

Multiple-input multiple-output (MIMO) Rayleigh fading channel with truncated Laplacian azimuth power spectrum (APS) is studied. By using the power correlation matrix of MIMO channel model and the modified Jakes simulator, into which random phases are inserted, the effect of the azimuth spread (AS), angle of departure (AOD) and angle of arrival (AOA) on the spatial correlation coefficient and ch...

background & aim: this experiment was conducted to examine the effect of different levels of echinacea purpurea (ep) in comparison with an antibiotic (flavofosfolipol) on total antioxidant activity (aoa) in serum of broiler chicks. experimental: in this trial 240 one-day-old broiler chicks (ross 308) were weighed and randomly assigned to the 5 treatment groups, each with 4 replicates with 1...
