The concentration of real convergence in a short period before the Great Recession (2001-2008) is characteristic shared by many countries, but it was particularly pronounced Croatia, Serbia, Bosnia and Herzegovina Bulgaria. Bulgaria managed to converge after Recession, other mentioned countries meagre; Slovenia even diverged since 2010. Direct effects post-Yugoslav wars belong past, indirect ma...

Background: Diagnosis of obstructive sleep apnea syndrome (OSAS) is valuable, but it is time-consuming and expensive. Appropriate screening instruments help clinicians select high-risk individuals for further investigations. In the present study, we compared 4 popular instruments used in screening OSAS including Berlin, STOP, STOP-BANG questionnaires, and Epworth Sleepiness Scale (ESS).  ...

A good knowledge of the parameters causing casing damage is critically important due to vital role of casing during the life of a well. Cement sheath, which fills in the gap between the casing and wellbore wall, has a profound effect on the resistance of the casing against applied loads. Most of the empirical equations proposed to estimate the collapse resistance of casing ignore the effects of...

At the beginning of millennium, a good decade after fall Berlin Wall and subsequent post-socialist transitions, there seemed to be positive outlook on prospects united Europe. However, twenty years later, future EU project looks much grimmer. The European Union has witnessed Brexit as well ‘democratic back-sliding’ both in ‘older’ ‘newer’ Member States. That is why, contributors “The Europeanis...

The model under consideration is a semi-infinite two-dimensional two-component plasma (Coulomb gas), stable against bulk collapse for the dimensionless coupling constant β < 2, in contact with a dielectric wall of dielectric constant = 0. The model is mapped onto an integrable sine-Gordon theory with a “free” Neumann boundary condition. Using recent results on a reflection relationship between ...

Sharptooth catfish, Clarias gariepinus, from the Rietvlei Dam near Pretoria, South Africa were examined for internal platyhelminth parasites. Two adult cestodes, Polyonchobothrium clarias (stomach) (prevalence 71%, mean intensity = 5, n = 7) and Proteocephalus glanduliger (anterior intestine) (prevalence 14%, mean intensity = 2, n = 7), were found in the gut while metacercariae of one larval di...

long-term mechanical circulatory support is a life-saving technology while briding to heart transplantation. it increases the quality of life and preserves end-organ function for patients with  advanced heart failure. the number of patients with advanced heart failure scheduled for heart transplantation before comorbidities escalate is on the rise. however, the device function is complicated by...
