Sustainable exploitation is widely advocated as a strategy for reconciling economic pressures upon natural habitats with nature conservation. Two recent papers examine different aspects of the sustainability of the nut harvest on wild populations of Brazil nut trees Bertholletia excelsa in Amazonia. Peres et al. find that many populations of the Brazil nut tree lack juvenile trees and are not r...

Hair cells detect and process sound and movement information, and transmit this with remarkable precision and efficiency to afferent neurons via specialized ribbon synapses. The zebrafish is emerging as a powerful model for genetic analysis of hair cell development and function both in vitro and in vivo. However, the full exploitation of the zebrafish is currently limited by the difficulty in o...

conclusions even though the osgt is an effective technique for inculcating an optimistic attribution style in delinquent boys, this important method needs to be continually implemented in their education. results the results showed that the osgt changed the attributional styles of delinquent boys from pessimistic to optimistic. also, the follow up study showed that the effect on the delinquent ...

To address the issue of minimum mesh size regulations stow net fishery for croaker species, we tested and compared selectivity exploitation pattern diamond- square-mesh codends with sizes 35, 45 55 mm little yellow (Larimichthys polyactis), silver (Pennahia argentata), flower (Nibea albiflora) in Yellow Sea, China. Our results showed that legal codend (35 diamond-mesh) was inadequate to protect...

conclusions juvenile xanthogranuloma is a cutaneous fibrohistiocytic lesion, which is rarely reported on palms. it is recommended to excise any soft tissue masses in children due to their possible association with malignancy. introduction juvenile xanthogranuloma (jxg) is a non-langerhans-cell histiocytosis, a group of histiocytic proliferative disorders, seen throughout the first two decades o...

Length-Based Spawning Potential Ratio (LB-SPR) model was applied to describe the status of Javelin grunter, Pomadasys kaakan in the Persian Gulf and Oman Sea. From April 2002 to March 2019. 45,489 specimens were collected from fish landing sites monthly, and their length (FL) and weight were measured. The results of the present study showed that different gears captured most of the P. kaakan be...

Juvenile ossifying fibroma (JOF) is a rare, benign, locally aggressive entity of the extragnathic craniofacial bones with a high tendency towards recurrence. Two distinctive microscopic patterns of juvenile ossifying fibroma have been described: a trabecular juvenile ossifying fibroma (TrJOF) and a psammomatoid juvenile ossifying fibroma (PJOF). Psammomatoid variant is predominantly a craniofac...

• Research has demonstrated that good supervision is associated with job satisfaction, commitment to the organisation and retention. • Supervision appears to help reduce staff turnover and is significantly linked to employees' perceptions of the support they receive from the organisation. • Good supervision is correlated with perceived worker effectiveness. There is some evidence that group sup...
