We examined the 52-yr sawlog price trends for the 10 commercial hardwood tree species in Ohio. Data were compiled from the Ohio Timber Price Report for four log grades (Prime, #1, #2, Blocking) covering the years 1960–2011, and average annual percentage rates of change in both nominal and real sawlog prices were determined. We further compared real log grade price movements within each species....

To investigate the composition distribution that develops in continuously-cast steel during a grade change, an efficient, accurate, and user-friendly computational model has been developed. The model is fully transient and consists of three submodels, which account for mixing in the tundish, mixing in the liquid core of the strand, and solidification. The first submodel of mixing in the tundish...

the effects of aflatoxin (af) (0.0 and 0.5m g kg-1) and high grade sodium bentonite (hgsb) (5, 7.5 and 10 g kg-1) were tested in an in vivo study including 8 dietary treatments with three replicates of 14 birds per diet per replicate, using a total of 336 broiler chicks up to five weeks. results showed that chicks receiving af contaminated feed had significantly (p≤ 0.05) suppressed body weight...

background & aim: the most common primary brain tumors of the central nervous system are gliomas. among a number of different biomolecular events, a strong relation between oxidative stress pathways and the development of this cancer has been proved. oxidative stress (os) is the consequence of an imbalance between pro-oxidants and antioxidants towards pro-oxidants. the pro-oxidants cause lipid ...

We assessed how children's self-concepts of ability for mathematics, English, social, and physical skills activities, ratings of the importance of these activities, and general self-esteem change across the transition to junior high school. Three types of change were assessed: change in mean levels, change in stability, and change in relationships. Twice each year during the sixth and seventh g...

background non-alcoholic fatty liver disease (nafld) is a common liver disease in the western population and expanding disease in the world. pathological changes in fatty liver are like alcohol liver damage, which can lead to end-stage liver disease. the prevalence of nafld in obese or overweight people is higher than general population, and it seems that people with high body mass index (bmi) ...

The new copper processing plant of the Sarcheshmeh copper complex consists of two parallel circuits. After a primary crushing, the ore is sent to a SAG mill, and the product is further ground in a ball mill. The overflow of the hydrocyclones is fed to a flotation circuit that contains 8 rougher tank cells (RCS130), 3 cleaner cells (RCS50), 5 scavenger cells (RCS50), and a flotation column (as r...

The developments in Norwegian sheep breeding since the early 1990s are reviewed. For the largest breeding population, the Norwegian White Sheep, results are presented for both genetic and phenotypic changes. Of the nine traits that make up the aggregate genotype, the largest gain per year, in per cent of the corresponding phenotypic average, was found for carcass grade (1.66%) and carcass weigh...

To establish Lactate dehydrogenase (LDH) isoenzyme is a biochemical tumor marker in cervical carcinoma patients for diagnosis and treatment monitoring of the disease. The Serum and cervical tissue LDH isoenzyme was analyzed qualitatively by Poly Acrylamide Disc Gel Electrophoresis method. The total LDH activity was estimated quantitatively by the method of UV spectrophotometry. 50 untreated cer...
