Feral Pigeons have colonised all corners of the Earth, having developed a close association with humans and their activities. The wild ancestor of the Feral Pigeon, the Rock Dove, is a species of rocky habitats, nesting typically on cliff ledges and at the entrance to large caves. This habit would have brought them into close contact with cave-dwelling humans, a relationship usually linked to t...

Rhinoliths are rare foreign bodies of the nose formed by in situ mineralization of endogenous or exogenous foreign material. They are often asymptomatic but may have various clinical presentations, with purulent rhinorrhea and nasal obstruction being the most common. They may go unnoticed for a long period and be diagnosed accidentally during a routine examination. We report a 6.5-year-old girl...

The purpose of this paper is to set endogenous or new growth theory against broader developments within economics as a discipline. As a topic, irrespective of its intellectual antecedents, endogenous growth theory is extremely recent, only dating back in acknowledged published form to Romer's (1986) article which is usually coupled with Lucas' (1988) contribution. Within a decade, the literatur...

Percutaneous pulmonary balloon valvuloplasty (PBV) remains the treatment of choice for pulmonary stenosis (PS). This procedure is effective, safe and gives excellent results. Pulmonary artery (PA) dissection is a rare complication of PBV. This report is a case of an asymptomatic 17-year-old male with a history of PBV due to severe PS dating back to fifteen years ago. During recent echocardiogra...

The interactions between bees that depend on floral oil for their larvae and flowers that offer oil involve an intricate mix of obligate and facultative mutualisms. Using recent phylogenies, new data on oil-offering Cucurbitaceae, and molecular-dating, we ask when and how often oil-offering flowers and oil-foraging bees evolved, and how frequently these traits were lost in the cause of evolutio...
