background: to reduce traffic injuries in the country, health professionals should have accurate estimates of road traffic deaths. multiple and sometimes inconsistent statistics presented by organizations in charge create high degree of uncertainty for planners and decision makers. to achieve an accurate estimate, several methods are available. of them, capture-recapture method seems to be an a...

antibody detection is the most versatile and commonly used method for measles diagnosis. detection of specific igm antibodies in a single serum specimen collected within the appropriate time after rash onset can provide a good presumptive diagnosis of current or recent measles infection and is the test of choice for rapid diagnosis of measles cases. so, optimal timing for collection of a single...

background: in neutron interaction with matter and reduction of neutron energy due to multiple scatterings to the thermal energy range, increasing the probability of thermal neutron capture by neutron captures makes dose enhancement in the tumors loaded with these materials.   objective: the purpose of this study is to evaluate dose distribution in the presence of  10 b ,  157 gd  and  33 s  ne...

Both capture-recapture and band-recovery studies can be conveniently modelled by one approach. The key is to view these methods as studies of cohort survival processes. Thus, in capture-recapture, as in band-recovery, attention is focused on survival rate, not population size. Probability models for the data are conditional on the known releases initiating each cohort. The first resampling of a...

liver samples from golden jackal (canis aureus) were collected from noor in the central coastline mazandaran province. the samples of this study were killed in road accidents. levels of persistent organochlorine pollutants (pops) including polychlorinated biphenyls (pcbs), ddts and metabolites, hexachlorocyclohexanes (hchs) and metabolites, hexachlorobenzene (hcb), aldrin and dieldrin were meas...

Free-ranging California sea lions ( Zalophus californianus ) with marine debris entanglements were darted with a combination of medetomidine, butorphanol, and midazolam by using acoustic transmitter-equipped darts. Of the 15 animals sedated, 13 (87%) reentered the water and were tracked by using a unidirectional hydrophone. Sea lions that entered the water continued to surface and breathe posts...

The importance of capturing wild animals for research and conservation projects is widely shared. As this activity continues to become more common, the need to assess its negative effects increases so as to ensure ethical standards and the validity of research results. Increasing evidence has revealed that indirect (physiological and behavioural) effects of capture are as important as direct ri...

An intramolecular palladium catalysed carbometalation followed by anion capture achieves construction of a model comprised of the A ring of Vitamin D oxygen analogues.
