Human health and chemical mixtures: an overview

Autor: Kathleen F. Arcaro, William D. Niemi, Dilip D. Vakharia, S Pang, David O. Carpenter, Brian Bush

Publikováno v: Environmental Health Perspectives

Unlike laboratory animals, people are rarely exposed to a single hazardous chemical. However, most of the information documenting adverse human health effects from environmental and occupational contaminants has come from studies focused on exposure

COMPUTERIZED METHODOLOGY FOR THE EVALUATION OF LEVEL OF KNOWLEDGE

Autor: R. Dennis, D. Niemi, Vladimir S. Lerner, H. Herl, J. Novak

Publikováno v: Cybernetics and Systems. 24:473-508

This article considers, the problem of a formal representation and identification of an individual's level of knowledge. Knowledge is considered as the systematic structurization of information received in perception. The computer implemented methodo

Effect of Ultrasonic-Assisted Preparation of Powders on Synthesis of Rare Earth Zirconates

Autor: D. Niemiec, M. Mikuśkiewicz

Publikováno v: Archives of Metallurgy and Materials, Vol vol. 65, Iss No 1, Pp 417-422 (2020)

The aim of the research was to determine the effect of sonochemical treatments on homogenization of powders as well as phase composition and thermal stability of sinters. The compounds were prepared from Eu2O3 and ZrO2 powders, weighed in the mass ra

PCBs reduce long-term potentiation in the CA1 region of rat hippocampus

Autor: David O. Carpenter, Jennifer Audi, William D. Niemi, Brian Bush

Publikováno v: Experimental neurology. 151(1)

Prenatal exposure to polychlorinated biphenyls (PCBs) has been associated with a lower IQ in childhood. We have examined the effects of acute exposure to PCB mixtures and two single congeners on synaptic transmission between Schaffer collaterals and

Propylthiouracil treatment reduces long-term potentiation in area CA1 of neonatal rat hippocampus

Autor: David O. Carpenter, Robert Rej, Kelly Slivinski, William D. Niemi, Jennifer Audi

Publikováno v: Neuroscience letters. 210(2)

Rat pups were made hypothyroid by exposure to propylthiouracil in drinking water beginning at 1 week of age, and the degree of long-term potentiation (LTP) in hippocampal area CA1 determined from brain slices of animals ranging in age from 2 to 6 wee
