Abstract This article proposes a new approach to estimate the informal economy (IE) by using Structural Equation Modeling (SEM). Using Monte Carlo Simulation and empirical analysis of Italian IE as an example, we provide general conclusions on reliability limitations SEM IE. Practical guidelines how apply this method way deal with most problematic issues are provided. We conclude that may be ef...

The tumor doubling time (TDT) of 50 measurable pulmonary cancers (primary and metastatic) has been evaluated by the Collins graphic method. The prognosis value of the TDT has been discussed in correlation with some current clinical and laboratory features, ie sex, age, erythrocyte sedimentation rate, tuberculin cutaneous response, size of the tumor on the first roentgenogram, and clinical sympt...

A total of 14 cases of infective endocarditis (IE) in children aged 6 months to 10 years were seen from December 1987 to December 1992 at the pediatric unit of Ayatollah Taleghani Medical Center. The majority of patients (12 of 14) were between 5 and 10 years of age. Acyanotic congenital heart disease was known to preexist in 78.6% and rheumatic valvular heart disease in 21.4% of cases. Or...

Multiple sclerosis (MS) and migraine are two common neurological disorders affecting women more than men. Sleep quality impairment has been reported in both diseases. The goal of this study was to compare sleep quality and depression between women with MS and migraine. Seventy women with migraine and 75 women with MS were enrolled in this study. Participants were asked to fill-out valid and rel...

Noise can enhance the detection and transmission of weak signals in certain nonlinear systems, via a mechanism known as stochastic resonance. Here we show that input noise can be used to improve motor control in humans. Specifically, we show that the postural sway of both young and elderly individuals during quiet standing can be significantly reduced by applying subsensory mechanical noise to ...

Many researchers worldwide have acknowledged the importance of teachers’ attitudes towards Inclusive Education (IE). The main objective this research is to explore factors influencing IE. A total 439 in-service teachers working under Ministry and 305 pre-service studying at Universities in Myanmar were included study. results indicated that both showed somewhat positive inclusion. Nevertheless,...

The strong contribution of RAS-related protein 1b (Rap1b) to cytoskeleton remodeling determines intracellular and extracellular physiological activities, including the successful infection viruses in permissive cells, but its role HSV-1 life cycle is still unclear. Here, we demonstrated that immediate early (IE) gene ICP4 inhibits kinase A (PKA) phosphorylation induce Rap1b-activation-mediated ...
