Transitions between states of a magnetic system can occur by jumps over an energy barrier or by quantum mechanical tunneling through the energy barrier. The rate of such transitions is an important consideration when the stability of magnetic states is assessed for example for nanoscale candidates for data storage devices. The shift in transition mechanism from jumps to tunneling as the tempera...

The purpose of this study was to assess the efficacy of a home-based well-rounded exercise program (WREP) in older adults. Forty sedentary community-dwelling older adults were randomly assigned to an exercise group (n = 23; aged 62-80 yr, average: 69.2 ± 5.2; 12 men and 11 women) or a control group (n = 17; aged 63-85 yr, average: 70.1 ± 6.6; 5 men and 12 women). The exercise group performed a ...

Isolated bilateral fractures of the coronoid processes of the mandible occurred in this patient without any significant trauma. The definite etiology of this case is unknown, but possible causes or contributing factors may include acute reflex contraction of the patient's temporalis muscles leading to bilateral stress fractures, coronoid process hyperplasia, or the patient's long-term use of om...

Objectives: To compare the force decay rate of the four brands of elastomeric chain over time and finally establish a gradation of brands in terms of force degradation characteristics. Materials and Methods: In this study total of two hundred and forty elastics were used. It had elastics of the same size from four different manufacturers. The experiment was carried out in vivo. For each patient...

Here is a case report of 16 year old female patient with Class III malocclusion molar relation on both sides. The was diagnosed normodivergent face pattern, proclined upper anterior, and crowded lower concave profile, potentially competent lips, reverse overjet 0% overbite, shallow mentolabial sulcus. treatment planned maxillary splint, mini-screws in mandible, elastics for Phase 1 2 fixed appl...

Anchorage conservation has always been a challenge in orthodontics especially in cases requiring group movement of teeth. The drawbacks of conventional anchorage conservation methods like headgears and intermaxillary elastics have been overcome with the advent of skeletal anchorage. Mini-implants which have been proved successful in several intraoral locations for anchorage, can also be success...
