Methods: Thirty Wistar rats were divided into three groups of 10 animals each: GI, GII and GIII and the mice were euthanized at 7, 14 and 21 days, respectively. Experimental subjects were compared to their respective controls by the Mann-Whitney test. Comparison of values between compression and tension sides were performed during the same and different time periods through Analysis of Variance...

In this paper we have studied Node Recovery in Wireless Sensor Networks (WSNs) and analyzed and reviewed two very interesting node recovery techniques; Recovery through Inward Motion (RIM) and Least Distance Movement Recovery (LDMR). We have compared both the techniques based on different performance metrics and presented the results.

UNLABELLED The need for long-term retention to prevent post-treatment tooth movement is now widely accepted by orthodontists. This may be achieved with removable retainers or permanent bonded retainers. This article aims to provide simple guidance for the dentist on how to maintain and repair both removable and fixed retainers. CLINICAL RELEVANCE The general dental practitioner is more likely...

In the present study the leaf movement rhythm was perturbed by the application of DC current pulses (15 microA, 10 seconds, voltage applied: 10 V) to the upper part of the pulvinus, passing through the pulvinus and its stalk. The pulses were applied at four different positions of the leaflets: when the leaves were at the lowermost position, when moving up, at the uppermost position and when mov...

FOUNDATION OF ESTHETIC DENTISTRY Cosmetic and esthetic dental outcomes are essential to meet patients’ high expectations and positively influence their self-esteem.1,2 Shape and color determine the aesthetics of both natural and restored teeth.3-6 Attractive restorative and prosthodontic outcomes begin with a consistent buccal shape and silhouette that reflect light.7 The perceived color of nat...

Two experiments are reported in which a pitch-level difference (PLD) model for prominence perception [Hermes and Rump, J. Acoust. Soc. Am. 96, 83-92 (1994)] is subjected to further tests. The model holds that the contribution of pitch to the perceived degree of prominence is proportional to the difference in pitch level between the vocalic nuclei of the accented and the previous syllable. In ex...

Effort rupture of the diaphragm is rare and accounts for only 1% of all diaphragmatic injuries. A 23 year old patient with bilateral rupture that followed sudden movement is described.

BACKGROUND The demand for clear sequential aligner therapy has increased dramatically in recent years. An improved system utilising small neodymium-iron-boron (NdFeB) magnetic attachments has been proposed to enhance appliance capabilities. AIM The aim of the investigation was to analyse the force system diagrams produced by small attracting NdFeB magnets to determine, 1) whether the force le...

Fundamentally, scientific research aims at contributing to the development of human knowledge in all areas, being systematically planned and executed according to rigorous criteria of information processing.1 It consists of investigations, observations and experiments, and tries to use these tools to explain the causes of many phenomena. When reading scientific articles of which purpose is to e...
