background marine sponge/nano-cuo as a natural catalyst efficiently catalyzed the sulfonylation reaction of p-chlorobenzene sulfonyl chlorides with amines in order to prepare sulfonamides. the advantages included use of a natural catalyst, ease of handling, requirement of a very small amount of catalyst, mild reaction condition and appropriateness to high yield. objectives the current study aim...

Effective spatial management of coral reefs including design of marine protected areas requires an understanding of interpopulation genetic connectivity. We assessed gene flow along 355 km of the Florida reef system and between Florida and Belize in three commensal invertebrates occupying the same host sponge (Callyspongia vaginalis) but displaying contrasting reproductive dispersal strategies:...

the potential of quince powder was evaluated for the production of fiber rich sponge cakes. in this study, quinces slices were dried in an infrared–hot air dryer (375 w, 60°c and 1 m/s flow rate). the rheological properties of cake batters and physico-chemical, textural and sensory properties of the sponge cake supplemented with five different concentrations (control, 5, 10, 15 and 20 %) of qui...

Aim: Neck hanging is one of the most lethal suicide methods. The morbidity and mortality due to hanging is usually associated with neck’s structure injury attached to a fall from height, venous obstruction and cerebral hypoxia time. Mortality is usually caused by respiratory failure in patients who recovered from hanging. In this study, we aimed to investigate effective factors on mortality in ...

Accidental hanging in children, although uncommon, has been reported worldwide. We report a case of a toddler who was brought to our hospital with an alleged history of hanging with his head trapped in-between the railings of a balcony. He became unconscious and developed seizures secondary to asphyxial injury and survived. Hanging is an important cause of homicidal and suicidal injury in adult...
