C++ is the most commonly used language in introductory and intermediate programming courses in Bulgarian universities. In recent years this language has developed greatly. Its abstractions are more flexible and affordable than ever before. Such great number of changes are related to the launch of the new standard (known as C++11) that we have grounds to consider it even a new language. It is in...

introduction the city population, in particular at the industrialized cities and centers of provinces, has increased dramatically in iran during recent decades. arak city is among of those industrialized cities as a centers of markazi province which has experienced a fast increase in population. this changes in population numbers tend to increase in consuming water resources as well as increasi...

The presence of paranoid thoughts is not exclusive to clinical disorder; recent data suggest that their prevalence follows an exponential-shaped curve, with many people experiencing a few such thoughts, while a few people experience many such thoughts. Wong et al (pp. 221–229) found that this exponential curve was also evident in their assessment of paranoid thoughts in children, but the freque...

OBJECTIVE Accurate measurement of temperature is vital in the intensive care setting. A prospective trial was performed to compare the accuracy of tympanic, urinary, and axillary temperatures with that of pulmonary artery (PA) core temperature measurements. DESIGN A total of 110 patients were enrolled in a prospective observational cohort study. SETTING Multidisciplinary intensive care unit...

Previous self-harm is a major predictor of non-fatal repetition and subsequent suicide. Owens et al (pp. 193–199), in a systematic review, estimate the rates of these outcomes following self-harm and find the link between self-harm and suicide to be a strong one. Non-fatal repetition occurred in around 15% of people in the year after an attempt, with up to 2% committing suicide over this time. ...

In 2003, Pelantová and Twarock did research into the number of, and types of, tiles found in 1-dimensional cut and project quasicrystals associated with 7-order symmetry. In this paper we extend this to symmetries of order 9 (degree 3), as well as orders 15, 16, 20 and 24 (degree 4). Some discussion of the next case, order 11 (degree 5), is given.

The purpose of this paper is to extend the results in [11] in the case of del Pezzo fibrations of degree 1. To this end we investigate the anticanonical linear systems of del Pezzo surfaces of degree 1. We then classify all possible effective anticanonical divisors on Gorenstein del Pezzo surfaces of degree 1 with canonical singularities. Mathematical Subject Classification (2000). 14D06, 14E05...
