Viability and fertility components of selection associated with linkage blocks marked by four electrophoretically detectable loci were estimated in an experimental population of barley [Composite Cross V (CCV)]. The intensity of selection affecting the distribution of pollen types in the outcross pool was also estimated and comparisons were made between the selective values of genes in the pool...

The modulation of spinal cord excitability during rhythmic limb movement reflects the neuronal coordination underlying actions of the arms and legs. Integration of network activity in the spinal cord can be assessed by reflex variability between the limbs, an approach so far very little studied. The present work addresses this question by eliciting Hoffmann (H-) reflexes in both limbs to assess...

Cycle-to-cycle variations (CCV) in spark-ignited (SI) engines impose performance limitations and the extreme limit can lead to very strong, potentially damaging cycles. Thus, CCV force sub-optimal engine operating conditions. A deeper understanding of is key enabling control strategies, improving design reducing negative impact on operation. This paper presents a new simulation strategy which a...

Esta pesquisa tem como objetivo mapear o percurso percorrido pela criança na produção das líquidas /l, ɾ/ em ataques simples e complexos Português Brasileiro, delineando a interação entre aquisição segmental silábica durante desenvolvimento fonológico. Um estudo experimental comparando de 71 crianças 2;0 5;11 anos foi conduzido para responder três questões: i) CCV ocorre somente após CV, ou pod...

In 1990 Subramanian de ned the complexity class CC as the set of problems log-space reducible to the comparator circuit value problem (Ccv). He and Mayr showed that NL⊆CC⊆P, and proved that in addition to Ccv several other problems are complete for CC, including the stable marriage problem, and nding the lexicographically rst maximal matching in a bipartite graph. Although the class has not rec...

Many low- and middle-income countries (LMICs) report low rates of regional anesthesia (RA) use for cesarean delivery (CD), despite its association with lower maternal major morbidity and mortality. Also, the prevalence of neuraxial analgesia for labor (NAL) is often low in LMICs. We report on the results of a collaboration in clinical education over a multi-year period between Kybele Inc., an i...

Aim . To compare the efficacy and safety of chemical cardioversion (CCV) with refralon amiodarone in patients paroxysmal atrial fibril­lation flutter (AF/AFL). Material methods Fifty five (mean age, 65±11 years) AF/AFL were included. All underwent a preliminary examination to rule out contraindications CCV. Further, randomized into groups (n=30) (n=28), respectively. CCV was carried as follows:...

Museums, archives and other cultural image collections, often are requested to identify an image whose metadata are inaccurate or missing. The task is further complicated because the query image may be an extract of the original, and present distortions, such as scale changes and noise. The majority of solutions proposed to this task are based on classic image signatures, such as the color hist...
