The known ore deposits and mineralization trends are important key exploration criteria in mineral exploration within a specific region. Fry analysis has conventionally been considered as a suitable method to determine the mineralization trends related to linear structures. Based upon literature sources, to date, no investigation has been carried out that includes the Sensitivity Analysis of Fe...
Early life is believed to be a critical stage for determining survivorship in all fish. Many studies have suggested that environmental conditions in the ocean determine the fry-to-adult survival rate of Pacific salmon but few investigations have been conducted on the importance of the brief freshwater period during the seaward migration on overall survivorship. Here, we found that most of the v...
—A 90-d ammonia toxicity test for early life stage rainbow trout Oncorhynchus mykiss was conducted using newly fertilized eggs from a wild strain of fish. The toxicity test was conducted at a pH of 7.75 and temperature of 11.48C. Hatch success and survival of sac fry were not affected by ammonia exposure. Survival, growth, and biomass of swim-up fry were significantly reduced at an ammonia-nitr...
This thesis deals with important factors that affect the temporal organization of emergence and early survival of Baltic salmon (Salmo salar L.). The study population was obtained from the Norrfors hatchery (63°50'N,20°05'E), Umeälven (Urne river) in Northern Sweden. The main objectives of the thesis has been to study; a: the effect of female and egg characteristics on embryonic survival, b: th...
The precise alignment of chromosomes on the metaphase plate prior to the onset of anaphase is essential for ensuring equal segregation of sister chromatids into two daughter cells, and defects in this process potentially cause chromosome instability and tumor progression [1-3]. NDR1 is an evolutionarily conserved serine/threonine kinase whose activity is regulated by MST kinases, Furry (Fry), a...

The purpose of this study was to examine the use of vocal fry in young adult Standard American-English (SAE) speakers. This was a preliminary attempt (1) to determine the prevalence of the use of this register in young adult college-aged American speakers and (2) to describe the acoustic characteristics of vocal fry in these speakers. Subjects were 34 female college students. They were native S...
The study evaluated the role of different substrates on water quality, growth and survival Labeo victorianus fry. Random sampling was used to select 225 fry, stocked at 100/m3 fed shell free artemia® (40% - 60% crude protein). Each treatment carried out in triplicates using gravel sand as media without substrate (control). Growth fry monitored over 4 weeks period a hatchery set-up. Physicochemi...

Research And Development Expansion of tilapia farming on a commercial scale was hindered by the limited availability of quality fry realized by researchers. Attempts were made to develop a practical technique of massscale fry production at the Asian Institute of Technology (AIT) in Klong Luang, Pathumthani, Thailand. A series of onstation trials were conducted over a decade, maintaining the Chi...
