Genetic and non-genetic correlations of the average somatic cell score (SCS) at different stages oflactation (100, 150, 200, 305 and 365 days in milk) with lactation performance were estimated based on thefirst lactation records of Iranian Holstein calving during 2000 to 2009. (Co) variance components wereestimated using derivative-free REML based on multiple traits animal models. The estimated...

Abstract. Given a doubling measure μ on R, it is a classical result of harmonic analysis that Calderón-Zygmund operators which are bounded in L(μ) are also of weak type (1, 1). Recently it has been shown that the same result holds if one substitutes the doubling condition on μ by a mild growth condition on μ. In this paper another proof of this result is given. The proof is very close in spirit...

A change in subtask order in the psychological refractory period (PRP) paradigm increases the effect of stimulus onset asynchrony (SOA) on the second response. We used a paradigm with cued, randomly determined subtask order to test the hypothesis that this SOA by order switch overadditivity reflects order control, via "copying" stimulus order. In Experiments 1a and 1b, overadditivity was eviden...

Passive samplers with two different collection substrates were used to obtain an average ozone concentration for 1 month during the summer of 2002 for each South Carolina county. One sampler contained a filter coated with indigo carmine, whose color fades when exposed to ozone. The fading was measured by reflectance spectroscopy. The other sampler contained filters that were coated with nitrite...

The hotel industry is an that can support the tourism sector, including one-star to five-star hotels. This study aims determine development of receivables collection at Hotel Z Jakarta, where there are many variations bad debts after 30 days. research analysis method used Accounts Receivable Turnover, Average Billing Period, Arrears Ratio, and Ratio. data obtained from this uses observation fin...

Garbage collection (GC) normally causes pause of execution. Parallel GC has a great potential for real time (non-disruptive) processing. A traditional parallel mark and sweep GC algorithm has, however, well known disadvantages. In this paper, we propose a new GC scheme called Partial Marking GC (PMGC) which is a valiant of generational GC. We implemented a Lisp interpreter with PMGC on a genera...

Although dual-task interference is ubiquitous in a variety of task domains, stop-signal studies suggest that response inhibition is not subject to such interference. Nevertheless, no study has directly examined stop-signal performance in a dual-task setting. In two experiments, stop-signal performance was examined in a psychological refractory period task, in which subjects inhibited one respon...

The standard bottleneck model of the psychological refractory period (PRP) assumes that the selection of the second response is postponed until the first response has been selected. Accordingly, dual-task interference is attributed to a single central-processing bottleneck involving decision and response selection, but not the execution of the response itself. In order to critically examine the...

We generalize the classical Cayley-Dickson doubling process starting with a quaternion algebra over a field F by allowing the scalar in the doubling to be an invertible element in the algebra. We investigate the resulting eight-dimensional algebras over F and show that they are division algebras for all scalars chosen in D outside of the base field F , if D is a division algebra.
