In this article, we report a surprising phenomenon: Oblique CF-varimax and oblique CF-quartimax rotation produced similar point estimates for rotated factor loadings and factor correlations but different standard error estimates in an empirical example. Influences of factor rotation on asymptotic standard errors are investigated using a numerical exploration method. The results are (a) CF-varim...

May and coworkers (l-3) demonstrated that the production of a scorbutic state in monkeys led to the development of a megaloblastic anemia, a condition which responded promptly to treatment with pteroylglutamic acid (PGA) or to very much smaller amounts of synthetic citrovorum factor (leucovorin or folinic acid-SF) .I It has been shown that the administration of ascorbic acid to normal human sub...

The mechanism by which cord factor (CF), a toxic glycolipid from mycobacteria, induces cachexia was studied in BALB/c mice. Body weight was markedly reduced 48 h after CF administration; the animals became severely wasted and exhibited hypertriglyceridemia, hypoglycemia, and high levels of tumor necrosis factor (TNF) in plasma. After CF administration, a transferable factor which caused cachexi...

The Length-Weight Relationship (LWR) and condition factors (CF) of 180 the oriental river prawn Macrobrachium nipponense collected from southern coasts of the Caspian Sea from May through September 2012 were studied. Shrimp samples were taken and immediately transferred to the laboratory of fish biology at University of Guilan for further analyses. Length, weight and other ext...

length-weight relationship and condition factor were investigated in seven fish species, including barbus cyri , capoeta gracilis , alburnoides eichwaldi , acanthalbarnus microlepis , ponticola cyrius , cobitis keyvani and oxynemacheilus bergianus from totkabon river. a total of 570 specimens ranging from 25.90 to 146.97 mm in total length and 0.1 to 260.3 g in total weight were collected. base...

this study was investigated reproductive differences in fall and spring migrants of caspian lamprey (caspiomyzon wagneri) in the shirud river (southern caspian sea)in 2008. 89 and 15 specimens were sampled in in spring and fall, respectively. generally, fall migratory fish had a significantly lower condition factor (cf) compared to the spring migrants. there was significant relationship between...

The Kolleru Lake is a famous Ramsar wetland of international significance. In this study heavy metal contents in water and sediment samples are reported. It is found that certain potentially toxic metal ions like chromium (4.5-80 µg/L), copper (1-20 µg/L), manganese (1-313 µg/L) and zinc (1.2-57 µg/L) are present in variable quantities in the lake water. When normalized with respect to concentr...

Shrimp is a marine culture found globally due to the ability of its yields boost country's economy. It imperative monitor size determine condition shrimp underwater with complex noise using non-invasive method. Therefore, this study aims develop new method for measuring body weight morphometric features based on image analysis and machine learning approach. The used consists several steps, data...

Thiamine (vitamin B1) deficiency of salmonines, caused by an abundant lipid-rich fish diet and consequently, the abundance polyunsaturated fatty acids, is called M74 syndrome in Baltic Sea. Because its deleterious effects on wild Atlantic salmon (Salmo salar) stocks progeny production cultivation, a model was developed to derive annual female-specific mortality percentages yolk-sac fry (YSFM) f...
