LORI (learning object review instrument) is an evaluation framework designed to support collaborative critique of multimedia learning resources. In this chapter, the interactions among reviewers using LORI are framed as a form of collaborative argumentation. Research on collaborative evaluation of learning resources has found that reviewers’ quality ratings tend to converge as a result of their...

the archaeological evidence suggests that iran has been one of the first origins of sheep domestication in the world. this study aims to investigate the genetic diversity of indigenous iranian sheep breeds using mitochondrial dna (mtdna) and to explore the evolutionary history of sheep domestication in iran. single nucleotide polymorphism (snp) markers in the control region of mtdna were used t...

Objective: The present investigation is aimed to develop and validate, a simple, consistent sensitive stability-indicating reverse phase-high performance liquid chromatography (RP-HPLC) method for the determination of oral anti-diabetic drug Canagliflozin in bulk pharmaceutical dosage form as per International Council Harmonization Technical Requirements Pharmaceuticals Human Use (ICH-Q2 (R1))....

this experiment was conducted to evaluate the effect of emulsifiers such as lecithin and bile salts onbroilers performances fed diet containing vegetable fats. 192 male ross broiler chickens were randomlyallocated in a factorial experiment design of 3 × 2, consisting two sources of fat (four percent fatty acidsor soy bean oil) and three emulsifiers (none, one percent lecithin and 0.05 percent b...

Dideoxy fingerprinting (ddF) was used as a tool to search for a generic set of conditions with sufficient power to detect virtually all mutations. For each condition tested, a very large sample of mutation-containing, single-stranded segments (about 1500) were analyzed with ddF. Correlation coefficients identified pairs of conditions in which single-strand conformation polymorphism (SSCP) mobil...

(Co)variance components and genetic parameters for test day ewe body weight of Lori-Bakhtiari sheep were estimated using a random regression model (RRM). The data consisted of 22153 individual body weight records, obtained from 1994 ewes (progeny of 205 sires and 1010 dams) between 371 and 3416 days of age, collected from the flock stud of Lori-Bakhtiari Sheep Breeding Station in Shahrekord, Ir...
