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...

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...

This study reports the presence of heavy metals (Cr, Ni, Cu, Cd, Pb) in sediment and water column Köyceğiz Lagoon Estuary System (KLES) (South-West Anatolia). The mean metal concentrations (µg L-1) were found as Cr: 3.72-8.36, Ni: 6.51-9.48, Cu: 1.29-11.88, Cd: ND-0.08, Pb: ND-0.34. samples to be below internationally acceptable limits. (mg kg-1) 1.75-4.25, 5.24-12.69, 0.25-0.51, <0.01, ...

While marine organisms such as bivalves, seagrasses and macroalgae are commonly used as biomonitors for the environment pollution assessment, widely distributed sponges received little attention as potential helpful species for monitoring programmes. In this study, the trace element and radionuclide bioaccumulation and retention capacities of some marine sponges were estimated in a species-comp...

Since oil is the primary source of vanadium in environment and crude has a correspondingly high percentage vanadium. Vanadium crucial as sign contamination. Twenty soil samples were taken from various locations surrounding East Baghdad field Iraq during February 2022 then analyzed to determine effects industrialization along with urbanization-related pollutants. The using spectrophotometry anal...

One of the most significant challenges that global decision-makers are concerned about is soil contamination. It also related to food security and fertility. The quality crops in Egypt being severely impacted by increased heavy metal content soils middle Nile Delta. In Egypt’s Delta, fifty random samples were chosen. Inverse distance weighting (IDW) was used create spatial pattern maps for four...

BACKGROUND, AIM AND SCOPE Water quality impairment by heavy metal contamination is on the rise worldwide. Phytoremediation technology has been increasingly applied to remediate wastewater and stormwater polluted by heavy metals. MATERIALS AND METHODS Laboratory analysis and field trials were conducted to evaluate the uptake of metals (Al, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, and Zn)...

Human activities around or within national highways, combined with atmospheric mixing, produce road dust, which can cause health problems through a variety of exposure routes. Thus, the study was aimed to investigate contamination, spatial distribution, potential ecological and human risks various toxic heavy metals such as lead (Pb), copper (Cu), chromium (Cr), cadmium (Cd), zinc (Zn), nickel ...
