This work presents a packet aggregation mechanism tailored for real time applications over wireless network environments. In the core of the proposed mechanism lies an elaborated packet holding time estimation. This estimation is used to allow for packet aggregation along a multihop path. The proposed mechanism was evaluated and compared with another(More)
This study aimed to evaluate the viability to use Uchi-komi (UK) in the evaluation of the judo endurance performance and using lactate threshold the analysis of the blood lactate ([Lac]) and heart rate (HR) determined through a lactate minimum test. The subjects were a group of 6 male, volunteer judokas, from 25.17 ± 5.76 years old, weight 84.50 ± 23.78 kg(More)
The objective of the present study was to assess any improvement in the IGT (Individual Glucose Threshold) of soldiers during military physical training (MPT). Nine healthy non-athlete recruits (mean weight: 66.3+/-7.9 kg; mean height: 1.77+/-0.05 cm; mean age: 18.4+/-0.5 year) were submitted to incremental ergometric test on a treadmill. The initial speed(More)
BACKGROUND Manual resistance training (MRT) is a low cost and practically applicable alternative form of resistance training that is ideal for weight rooms with limited equipment. The aim of this study was to compare the acute and sub acute hemodynamic responses between MRT and free weight resistance training (FWRT) in normotensive (NT) and hypertensive(More)
Background: The aim of this study was to compare the number of repetitions to volitional failure, the blood lactate concentration, and the perceived exertion to resistance training with and without an airflow-restricting mask. Methods: Eight participants participated in a randomized, counterbalanced, crossover study. Participants were assigned to an(More)
Polyaniline (PANI) was chemically synthesized on a dacron disk surface and an antigen (F1 fraction) obtained from Yersinia pestis was covalently fixed onto this composite via glutaraldehyde. The enzyme linked immunosorbent assay (ELISA) or rapid ELISA procedure detected immunoglobulin G (IgG) anti-F1 fraction in human serum employing this derivative. The(More)
This study verifies if caffeine supplementation delays the onset of fatigue, enhancing performance, and whether this effect is due to modulation of the caffeine in the rating of perceived exertion, motor drive activation, autonomic nervous system, and energy metabolism. Nine recreational athletes were submitted to two constant load tests after(More)
MOTIVATION It has been recently suggested that atomic burials, as expressed by molecular central distances, contain sufficient information to determine the tertiary structure of small globular proteins. A possible approach to structural determination from sequence could therefore involve a sequence-to-burial intermediate prediction step whose accuracy,(More)
