listeriosis is acknowledged as a major foodborne disease throughout the world caused by listeria monocytogenes. different factors can affect the growth of food borne microbial pathogens. the aim of this study was to investigate the combined effects of different concentrations of bunium persicum essential oil (eo) (0%, 0.08%, 0.16%, 0.24%), three incubation temperatures (35ºc, 25ºc, 4ºc), three ...

BACKGROUND Hierarchical partitioning (HP) is an analytical method of multiple regression that identifies the most likely causal factors while alleviating multicollinearity problems. Its use is increasing in ecology and conservation by its usefulness for complementing multiple regression analysis. A public-domain software "hier.part package" has been developed for running HP in R software. Its a...

confirmation of convergence hypothesis among provinces, its role in removing divergence among regions and achieving regional convergence is one of the important issues in macroeconomics. the aim of the present study is to examine absolute and conditional income convergence hypotheses among iranian provinces during the period 2000-2010 using panel data. the hypotheses are tested for the whole pr...

In some statistical process control applications, a relationship between a response variable and an explanatory variable referred to as profile characterize the quality of a process or product and should be monitored over time. Many researches have been done in this area but in most of them, the successive observations in different levels of the explanatory variables are assumed to be independe...

abstract the purpose of this paper is estimation of the effective factors on tea supply in gilan province by using time series data during 1360-1390 in the form of nerlove model. according to the results, explanatory variables of the model could describe 97 percent of dependent variable (product supply) changes. the results show that the guaranteed price index of green tea leaf with elasticity ...

In many scientific endeavors, it is common to examine the effects of more than a single explanatory variable on the response or outcome variable of interest. For example, in a placebo-controlled clinical trial examining the effects of a new cholesterol-lowering drug, the investigators may also classify participants in the study according to their obesity status (obese versus non-obese). When tw...

the augmented gravity model was employed to determine iran's trading model and agricultural export directions in the case of cross section analysis in 2005 for 64 countries which are considered as iran's main export market. besides, another explanatory variable named trade conformity index (tci) was added to the model. this index was employed to identify iran's trading model. als...

in some quality control applications, the quality of a process or a product is described by the relationship between a response variable and one or more explanatory variables, called a profile. moreover, in most practical applications, the qualitative characteristic of a product/service is vague, uncertain and linguistic and cannot be precisely stated. the purpose of this paper is to propose a ...
