Both for software developers and managers it is crucial to have clues about different aspects of the quality of their systems. Maintainability is probably the most attractive, observed and evaluated quality characteristic of all. The importance of maintainability lies in its very obvious and direct connection with the costs of altering the behavior of the software. In this paper we present an e...

This is a Supplemental online Appendix, containing additional theoretical and empirical results. 1 Supplemental Online Appendix Here we provide additional supplemental material. First is some details regarding extensions to higher order derivatives and larger than marginal changes in the threshold. Next is a second empirical application, showing application of our methods in a fuzzy design cont...

to determine chromosomal localization and relationship between field and laboratory indicators of drought tolerance, an experiment was conducted in 2003-2004 cropping season at sararood agricultural research station, kermanshah, iran. seven genotypes of wheat-barley disomic addition lines provided by international center for agricultural research in dryland areas (icarda), their donor and recip...

since crosses of lines with suitable genetic distance produce excellent hybrids, the identification of genetic diversity between zea mays l. inbred lines in hybrid maize breeding programs has a high priority. a total of 27 inbred lines plus b73 and mo17 (sc704 parents) were evaluated by 15 inter-simple sequence repeat (issr) primers. inbreds were selected randomly from inbred lines from the agr...

background: during the past few years, hesa-a, a herbal-marine mixture, has been used to treat cancer as an alternative medicine in iran. however, weight of the evidence is not sufficient to accept or refuse the use of this compound as a cytotoxic drug. we investigated the selective anticancer effects of hesa-a on breast, prostate, colon, and glioblastoma multiforme (gbm) neoplastic cell lines....

purpose: to assess the effect of emla® cream application without occlusive dressing on pain on needling (pn) and pain on injection (pi) felt during multiple botulinum toxin type a (bta) injections for correction of hyperkinetic upper facial lines methods: a prospective, randomized, double-blind, placebo-controlled clinical trial was conducted on 44 subjects seeking upper facial wrinkles correct...

few studies have been reported regarding probiotic properties of lactococcus lactis strains although they are extensively used as starter cultures in the production of dairy products. in this study 8 wild isolates of lactococcus lactis were evaluated in vitro with regard to resistance to simulated gastric and intestinal juices, adherence ability to caco-2 cells and ht29-mtx-e12 cell lines, anti...

objective(s): the oct4b1, as one of oct4 variants, is expressed in cancer cell lines and tissues more than other variants and plays an important role in apoptosis and stress (heat shock protein) pathways. the present study was designed to determine the effects of oct4b1 silencing on expressional profile of hsp40 gene family expression in three different human tumor cell lines. materials and met...

A cytogenetic study was performed on M4 generation of gamma irradiated lines of Shirpan cultivar of tetraploid cotton (Gossypium hirsutum L.). A significant difference was observed in cytogenetical characteristics such as the number and type of quadrivalents as well as percentage of cells showing abnormality among the irradiated and non irradiated lines. Cytomixis and post- pachytene diffuse st...

A new modification of the Method of Lines is proposed for the solution of first order partial differential equations. The accuracy of the method is shown with the matrix analysis. The method is applied to a number of test problems, on uniform grids, to compare the accuracy and computational efficiency with the standard method.
