ARTICLE INFO Schistosoma mansoni worms inhabit the portal triad affecting blood elements. Therefore, the current study aimed to compare ameliorative effects of Commiphora molmol extract (Mirazid, MZD) and praziquantel (PZQ) on some biochemical parameters in S. mansoni-infected mice. Accordingly, Swiss albino mice (n=72) were used and were divided into 4 equal groups; 18 mice each. Group (1) was...
PURPOSE The purpose of this study was to evaluate the contribution of working memory at the word and sentence levels of language to reading and writing outcomes. METHOD Measures of working memory at the word and sentence levels, reading and writing, were administered to 2nd (N = 122), 4th (N = 222), and 6th (N = 105) graders. Structural equation modeling was used to evaluate whether the 2 pre...
Proof of Observation 1. Before the proof, we remind that what we want to prove is the following statement: (∀ε ∈ R) ε > 0⇒ ((∃N ∈ N)(∀n ∈ N) n ≥ N ⇒ |an − x | < ε). To this end, choose arbitrary positive real ε > 0 and pick a positive rational ε′ with 0 < ε′ < ε by utilizing the Archimedean property. Then there exists N (depending on ε′ and hence on ε) such that j, k ≥ N ⇒ |a j − ak | < ε′. Now...
introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...
The host-stage preferences of alfalfa black aphid, Aphis craccivora, by parasitoid wasp, Lysiphlebus fabarum, were studied under two trials under growth chamber conditions (55±5 %, R. H., L:D 14:10 H. and Tem. 20 ±2° C ). In the first trial, all stages of aphid in equal ratios, and in the second trial, variable ratios of 5:15, 15:15 and 15:5 of 3rd and 4th instar nymphs were used for parasitisa...
Research on factors that may promote engagement is hampered by the absence of a measure of classroom-level engagement. Literature has suggested that engagement may have 3 dimensions--affective, behavioral, and cognitive. No existing engagement scales measure all 3 dimensions at the classroom level. The Classroom Engagement Inventory (CEI) was developed to fill this gap. In Study 1, exploratory ...
