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...

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...

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. ...

A stroma-dependent cell line (HB-1) was established from myelogenous leukemic cells of CBA/N mouse. Characterization of the cells showed that HB-1 proliferated on hematopoietic supportive stromal cells (MS-10), but did not survive or proliferate on hematopoietic nonsupportive cells (MS-K). Direct contact between HB-1 and MS-10 appears to be necessary for HB-1 to proliferate on MS-10. We found t...
