We reexamine a recently proposed non-inflationary solution to the monopole problem, based on the possibility that spontaneously broken Grand-Unified symmetries do not get restored at high temperature. We go beyond leading order by studying the self-consistent one-loop equations of the model. We find large next-to-leading corrections that reverse the lowest order results and cause symmetry resto...

One approach to the study of wear involves the ch~~te~zation of surface failure under conditions of single-pass sliding. Such an approach has been used to show that the wear of commercial and experimental restorative resins and composites is determined by the resistance of the material to penetration and by the mode of deformation during sliding [l] . The purpose of this investigation was to ch...

Six cases are described in which late reattachment of detached retina occurred 9-16 months after what had been considered to be failed retinal detachment surgery. In all cases reattachment had been associated with partial restoration of vision. No cause for such reattachment can be clearly established, but it is felt that spontaneous separation of the posterior vitreous face with subsequent rel...

Acute portal vein thrombosis (PVT) is a rare clinical condition that can cause portal hypertension and bowel infarction. Early diagnosis and treatment of PVT is crucial for the restoration of portal venous flow and reduction of morbidity and mortality. We report a successful treatment of acute PVT which was seen following splenectomy, utilizing catheter directed transhepatic thrombolysis. No co...

o bjectives: caries and dental trauma are common reasons for primary anterior teeth restorations in children. this non-control clinical trial was designed to eva- luate crown restorations reinforced with a sectioned file post for the restoration of severely damaged primary maxillary incisors. materials and methods: thirty-eight primary maxillary incisors of 12 children (3-5 years old) with earl...

introduction: the purpose of this in vitro study was to evaluate the sealing ability of the readymade temporary filling and hand mixed materials by assessing coronal microleakage. materials & methods: standardized access cavities were prepared in 80 intact human permanent premolar teeth. they were divided randomly into four experimental groups (n=20). the teeth were restored using one of the te...

Both fictional and factual discourses have situated visual impairment in a causal relationship with suicide. The paper compares samples of these discourses in order to suggest that the fiction may have some bearing on the facts. This alternative explanation becomes all the more thought-provoking when it is considered that not only visual impairment but visual restoration has been posited as a c...

nowadays, due to recent developments and researches in dental science, it is possible to preserve and restore previously extracted cases such as teeth with extensive caries, fractured or less appropriate cases for crown coverage as well as teeth with external perforation caused by restorative pins. in order to restore the teeth with preservation of periodontium, we should know thoroughly physio...

The face stability of shallow tunnels was investigated with small-scale model experiments at single gravity. Aim of the research was to detect the evolution of failure mechanisms in dense and loose soil samples with varying overburden above the tunnel. Moreover, the quality of proposed theoretical/numerical approaches for the determination of a necessary support pressure pf was assessed. The re...

Over the past three years, BMW has undertaken a significant project to first investigate, then proceed with migration from its present crash simulation software to ABAQUS. This project has been motivated by a growing recognition within BMW that, in order to advance its crash simulation methods, improved robustness in the software employed, along with a greater emphasis on physically-motivated s...
