Wax Teeth and Metallic Superstructure Trials at the Same Session: Simplified Technique for Implant-Supported Prosthesis

This clinical report describes a method to reduce the number of clinical sessions for the rehabilitation of implant-supported fixed dentures through a simplified and versatile procedure indicated mainly for immediate loading. According to this method, the immediate implant-supported fixed dentures for edentulous patients can be safely fabricated within 2 days. In this technique, the teeth in the wax are prepared on a base of light-polymerized resin, and both wax teeth and metallic superstructure trials are accomplished at the same session.

PHYSIOLOGICAL and NEUROMUSCULAR PROFILE DURING A BODYPUMP SESSION: ACUTE RESPONSES DURING A HIGH-RESISTANCE TRAINING SESSION

Oliveira, AS, Greco, CC, Pereira, MP, Figueira, TR, de Araujo Ruas, VD, Goncalves, M, and Denadai, BS. Physiological and neuromuscular profile during a Bodypump session: acute responses during a high-resistance training session. J Strength Cond Res 23(2): 579-586, 2009-The main purposes of this study were 1) to describe and to compare blood lactate ([La]), heart rate (HR), and electromyographic (EMG) parameters during high-repetition training sessions (HRTSs), 2) to analyze the influence of physical fitness levels in these parameters, and, 3) to analyze the relationship between metabolic ([La]) and neuromuscular (EMG) responses during the HRTS. Fifteen healthy untrained women (21.7 +/- 2.1 years) performed an HRTS called Bodypump for 1 hour, which incorporated the use of variable free weights and high repetitions in a group setting. This session involved 10 music selections (M1-M10) containing resistive exercises for different muscle groups. After music selections 2 (M2), 4 (M4), 6 (M6), 7 (M7), and 9 (M9), [La], HR, and EMG (vastus medialis [VM], vastus lateralis [VL], iliocostalis lumborum [IC], and longissimus thoracis <) were determined. The [La] (M2, 4.00 +/- 1.45 mM; M7, 5.02 +/- 1.73 mM) and HR (M2, 153.64 +/- 18.89 bpm; M7, 16.14 +/- 20.14 bpm) obtained at M2 and M7 were similar but were significantly higher than the other moments of the session. However, EMG (root mean square [RMS]) at M2 (VL, VM, and LT) was lower than at M7. There was no significant correlation of strength and aerobic physical fitness with [La], RMS. In the same way, there was no significant correlation of [La] with RMS at M2 and M7. on the basis of our data, we can conclude that metabolic, cardiovascular, and EMG variables present different and independent behavior during an HRTS. Accordingly, for neuromuscular conditions during HRTS, it seems to be enough to induce improvement in the muscular strength of inferior limbs in untrained subjects.

Correlates of session-rate of perceived exertion (RPE) in a karate training session

Objective. The aim of this study was to analyze the relationships between the rate of perceived exertion (RPE) of a whole exercise session (RPE-S) and objective measures of exercise intensity during a karate training session.Methods. Eight well-trained karate athletes performed a single training session involving basic karate techniques and sparring. Heart rate (HR) was continuously monitored, while blood lactate ([lac]13) and rating of perceived exertion using the Borg's 6-20 scale were taken each 10-min during exercise. Athletes were also asked to rate their RPE-S using a modified CR-10 scale 30-min after exercise.Results. Significant relationships (P<0.05) were found between RPE-S and mean values of %HRmax (r(p) = 0.91), %HR reserve (r(p) = 0.87), [lac]b(r(p) = 0.96), and RPE (r(p) = 0.78) during the session, but not between RPE-S and the duration of exercise bout (r(s) = 0.28; P > 0.05). RPE-S was also significantly related (P < 0.05) to percentage of time sustained under ventilatory thresold (VT) (r(p) = 0.96), between VT and respiratory compensation point (RCP) (r(p) = 0.93) and above RCP (r(p) = 0.96).Conclusion. These results suggest RPE-S to be a valid tool for assessing interindividual variations in global exercise intensity during karate training. (C) 2010 Elsevier Masson SAS. All rights reserved.

Conditional reasoning: A key to assessing computer-based knowledge-building communication processes

This article describes a methodological approach to conditional reasoning in online asynchronous learning environments such as Virtual-U VGroups, developed by SFU, BC, Canada, consistent with the notion of meaning implication: If part of a meaning C is embedded in B and a part of a meaning B is embedded in A, then A implies C in terms of meaning [Piaget 91]. A new transcript analysis technique was developed to assess the flows of conditional meaning implications and to identify the occurrence of hypotheses and connections among them in two human science graduate mixed-mode online courses offered in the summer/spring session of 1997 by SFU. Flows of conditional meaning implications were confronted with Virtual-U VGroups threads and results of the two courses were compared. Findings suggest that Virtual-U VGroups is a knowledge-building environment although the tree-like Virtual-U VGroups threads should be transformed into neuronal-like threads. Findings also suggest that formulating hypotheses together triggers a collaboratively problem-solving process that scaffolds knowledge-building in asynchronous learning environments: A pedagogical technique and an built-in tool for formulating hypotheses together are proposed. © Springer Pub.

Net melon cultivars productivity under different cultivation systems, during summer and winter

In order to access the effects of cultivation in soil, sand or a commercial substrate on the productivity of Bonus #2 cultivars, 'Don Carlos' and 'Hy Mark', two experiments were conducted in the greenhouse at FCAV-UNESP, Jaboticabal- SP, Brazil, 21° 15' 22 S, 48° 18'58 W, and altitude of 595 m, from November 1999 to April 2000 (summer), and from July to November 2000 (Winter). For cultivation in soil, chemical nutrients were added, and plants were irrigated with drip irrigation. Fertigation with recirculation of the nutrient solution was used on sand; slabs were used on commercial substrate with the fertigation with non circulating nutrient solution. Bonus #2 cultivar yielded the highest production of marketable fruit, but were later in production, while Hy Mark cultivar had early production but a lower number of fruit per plant. The winter planting yielded higher production of marketable fruit while summer plantings yielded lower number of fruit per plant, but with higher average weigh. The combination between cultivation systems and cultivars yielded higher fruit production in winter.
