BACKGROUND Current treatments for scoliosis have some defects and complications. To study spinal deformities and test novel scoliosis treatments, many animal models of scoliosis have been developed. These models applied a single load to the spine and could not precisely modulate the spinal growth in different dimensions. In this study, we applied posterior tethering in various directions with t...

Acquisition of sporadic community-acquired legionnaires' disease has been linked to hot springs and whirlpool baths. Outbreaks of hot spring-associated legionnaires' disease were reported in Japan in the last few years. Although the mode of transmission is unclear, the presence of Legionella in hot springs may discourage hot springs resort visits by the general public. An environmental survey w...

A new calculation method for disc springs with contact flats and reduced thickness is presented in this paper. The analysis aims at putting in evidence the contradiction in standard norms where the standard calculation method for this kind of Belleville springs is used. On the basis of this analysis it is found that standard methods do not work for reduced disc springs because they lead to dang...

Long-distance host-independent virus dispersal is poorly understood, especially for viruses found in isolated ecosystems. To demonstrate a possible dispersal mechanism, we show that bacteriophage T4, archaeal virus Sulfolobus spindle-shaped virus Kamchatka, and vaccinia virus are reversibly inactivated by mineralization in silica under conditions similar to volcanic hot springs. In contrast, ba...

This paper investigates the synthesis of a spatial stiffness matrix using simple line springs. A new algorithm is developed, which enables the selection of constituent springs based on their positions and directions. The constraining space of the line springs is then investigated. It is shown that an isotropic stiffness matrix, in general, can be split into the sum of two rank-3 stiffness matri...

OBJECTIVE The aim of this paper was to determine the amount of deformation in four commercial brands of nickel-titanium closed springs. METHODS A total of 130 springs were divided into 13 subgroups, according to their features and manufacturers (Morelli, Orthometric, Ormco and GAC) and activated from 100% to 1000% of the effective length of the nickel-titanium portion present at the spring, a...

eral incisors. EW springs were then bonded to anchor-wire segments as described above (Fig. 3). Three months later, the upper lateral incisors had been significantly intruded (Fig. 4). After the intrusion auxiliaries were removed, a bracket was bonded to the left lateral incisor for incorporation into the main archwire; an .008" ligature wire was bonded to the surface of the right lateral incis...

expense and have acceptably low revenue implications. Disturbances of cardiac rhythm are common in general practice,68 and Shaper was able to show electrocardiographic evidence of ischaemic heart disease in 15% of a large sample of men aged 40-59.9 Perhaps most tellingly, home care of patients with acute myocardial infarction cannot be contemplated without establishing the diagnosis. More recen...

Introduction Natural and artificial radionuclides are the main sources of human radiation exposure. These radionuclides, which are present in the environment, can be dissolved into water. Evidence suggests that radionuclides being entered the human body through drinking or hot spring water can be harmful for human health. Materials and Methods In this study,10 samples were collected from ground...
