BACKGROUND A study was undertaken to investigate the influence of the menstrual cycle on airway responsiveness and beta 2 adrenoceptor function in female asthmatic patients. It has previously been shown that normal women exhibit cyclical changes in beta 2 adrenoceptor function with an increase in beta 2 adrenoceptor density in the luteal phase during the premenstrual period. METHODS Fifteen w...

Three-dimensional printing can bring huge advantages when fabricating difficult structures and components in industry. This technology is also used commonly for threaded fasteners the engineering field. The main disadvantage of threated self-loosening. In this study, an International Organization Standardization (ISO) standard M12 × 1.75 bolt nut were printed by using a 3D printer three types m...

The paper presents a family of cycloidal cyclical surfaces, which are created by a movement of a circle alongside the special spatial cycloidal curve, where the circle is located in the curve normal plane and its centre is on this curve. The spatial cycloidal curve can be created by simultaneous revolution of a point about three different axes 3o,2 o and 1o in the space. The form of the cycloid...

I propose a method to estimate cyclical DSGE models using the raw data. The approach links the observables to the model counterparts via a ‡exible speci…cation which does not require that the cyclical component is solely located at business cycle frequencies and allows the noncyclical component to take various time series patterns. Applying standard data transformation induces distortions in st...

Enterovirus A71 (EV-A71) is an important emerging pathogen causing large epidemics of hand, foot and mouth disease (HFMD) in children. In Malaysia, since the first EV-A71 epidemic in 1997, recurrent cyclical epidemics have occurred every 2-3 years for reasons that remain unclear. We hypothesize that this cyclical pattern is due to changes in population immunity in children (measured as seroprev...
