INTRODUCTION Listeria monocytogenes is considered one of the most important food-borne pathogens transmitted to humans via contaminated food. The aim of the present study was to demonstrate the importance of L. monocytogenes as a food-borne pathogen. METHODOLOGY A total of 340 samples were collected from different localities in El Giza Governorate, Egypt, to check the occurrence of L. monocyt...

introduction: aflatoxin b1 (afb1) is one of the most well-known hepatocarcinogens in humans. contamination of raw materials, used in the production of sausages and burgers, with aflatoxin producing molds can lead to increased level of aflatoxin in the final products and can impose hazards to human health. unfortunately, aflatoxin is resistant to heating and freezing processes, etc. and can rema...

Foodborne pathogens have the main concern in public health and food safety. Bacillus cereus food poisoning is one of the most important foodborne pathogens worldwide. In the present study, a total of 200 random beef product samples were collected from different supermarkets located at Menofia and Cairo governorates were examined for the presence of B. cereus. In addition, the presence of some v...

What is the most effective way to grill food? Timing everything, since only one surface exposed heat at a given time. Should we flip once, or many times? We present simple model of cooking by flipping, and some interesting observations emerge. The rate depends on spectrum linear operator, fixed point map. If system has symmetric thermal properties, becomes independent sequence flips, as long la...

An application of the generalized tanh–coth method to search for exact solutions of nonlinear partial differential equations is analyzed. This method is used for variants of the KdV–Burger and the K(n, n)–Burger equations. The generalized tanh–coth method was used to construct periodic wave and solitary wave solutions of nonlinear evolution equations. This method is developed for searching exac...

We demonstrate how a non-nested statistical test developed by Vuong (1989) can be used to assess the suitability of alternate order-of-entry assumptions used for identification purposes in empirical entry models. As an example, we estimate an entry model of McDonald’s and Burger King restaurant outlets in United States. The data set focuses on relatively small “isolated” markets. For these mark...

abstract awareness of consumer reasons during nutrition choice is very important, because this decision directly affect their health. since beef is one of the essential goods in consumer basket of goods of iranian households, exploring of factors that influence consumers purchase decisions and intentions toward imported frozen beefs in east azerbaijan province – tabriz city is the purpose of th...
