The aim of this study was to screen potential probiotic bacteria against Aeromonas hydrophila and determine the effects of antagonistic bacteria and a commercial product containing lactic acid bacteria on the survival and growth of stage II Astacus leptodactylus juveniles. For this purpose, a total of 110 bacterial strains were isolated from adult, stage II crayfish juveniles and rearing water ...

Urbanism in third world and developing countries compared to that of developed countries has been increased with much more speed. From consequences of the population increase and accelerated growth of population in cities, reference can be lead to many problems such as increase of unemployment rate, housing problems, social anomalies, increase in crime and delinquency. Vandalism in public space...

There exists a national trend lowering the age to transfer children facing serious charges to adult court for trial. This study examined juvenile offenders' understanding of factual information about trials. Juveniles ages 11 through 16 experiencing their first institutional placement were administered a competence to stand trial screening measure, shown an educational videotape, and readminist...

The study tries to judge the relationship between juvenile delinquency and impact of media, heredity, environment, time, age, school performance, economic status, association etc. The significance of the relationships has been tested. Moreover, attempt has been made to study the influence of t...

Avascular necrosis of the talus after severe ankle injury is well known. Avascular necrosis of talus is extremely rare in juveniles. However, it has been controversial whether the incidence of AVN after fracture of talus is higher in adult than in juveniles. It is possible that the immature talus can be more susceptible to circulatory. As treatment of avascular necrosis of the talus, non-operat...

Adult passerines renew their flight feathers at least once every year. This complete moult occurs either in the breeding areas, just after breeding (summer moult), or, in some long-distance migratory species, at the non-breeding areas, after arrival to the southern wintering area at the end of autumn migration (winter moult). The aim of this study was to relate moult strategies with the DMD, th...

This study examined the play behaviour in one group of coatis (Nasua narica) at La Selva Biological Station in Costa Rica. We incidentally found adult males playing with juvenile coatis, and conducted post-hoc analyses to investigate this interaction. Coati groups consist of adult females and juveniles of both sexes until male juveniles reach two years of age and leave the band to become solita...

Measurements of second-stage juveniles of Heterodera schachtii from California and The Netherlands and a race of H. trifolii from The Netherlands were obtained and compared to determine if these populations can be differentiated by morphometrics. Juvenile lengths of 10 specimens from each of 10 cysts of each population were measured. Dimensions of tail regions of 20 juveniles from individual cy...

A lack of parental care is generally assumed to entail substantial fitness costs for offspring that ultimately select for the maintenance of family life across generations. However, it is unknown whether these costs arise when parental care is facultative, thus questioning their fundamental importance in the early evolution of family life. Here, we investigated the short-term, long-term and tra...
