The antibacterial activity of Citrus karna fruit peel extracts was evaluated on bacteria strains like Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Bacillus subtilis. Hexane, chloroform and methanol were used for extraction and the antibacterial activity was performed by agar well diffusion method. The results were compared with ampicillin, a commercial antibacterial agent...
Background: Aeromonas species are Gram-negative ubiquitous bacteria, facultative anaerobic rods that infect both invertebrates and vertebrates. Various fish species develop hemorrhagic disease and furunculosis due to Aeromonas spp. Aeromonas strains generate certain active compounds such as siderophores, which are the final products of non-ribosomal peptide synthetase (NRPS) activity. The prese...
the aim of this study has been to find answers for the following questions: 1. what is the effect of immediate correction on students pronunciation errors? 2. what would be the effect of teaching the more rgular patterns of english pronunciation? 3. is there any significant difference between the two methods of dealing with pronuciation errore, i. e., correction and the teaching of the regular ...
abstract: in this thesis, we focus to class of convex optimization problem whose objective function is given as a linear function and a convex function of a linear transformation of the decision variables and whose feasible region is a polytope. we show that there exists an optimal solution to this class of problems on a face of the constraint polytope of feasible region. based on this, we dev...
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
Background & objectives: Urinary tract infection (UTI) is one of the most common types of human infections and Escherichia coli and Klebsiella pneumonia are the main causes of urinary tract infection among the gram negative bacteria. The prevalence of extended-spectrum β-lactamases (ESBLs) among these bacteria and hence resistant strains to β-lactam antibiotics have increased in recent decades...

Background and Objective: Probiotic bacteria are microbial food supplements with beneficial properties on human health . The increase in the use of industrial dairy products instead of the traditional ones may enhance the possibility of missing the probiotic bacteria. The aim of this study was to isolate lactobacilli from local yogurts produced in rural areas of Rafsanjan and also to inves...
abstract: the potato tuberworm, phthorimaea operculella (zeller), is an important insect pest of potato (solanum tuberosum l.) in the storage and field in most parts of the world especially in tropical and subtropical regions due to its close relationship with the host, high reproductive potential and high economic losses. information on host preference, life table parameters and digestive en...
background: many efforts have been done to find effective agents against resistant pathogens. cuminum cyminum l. (cumin) is an aromatic plant within the apiaceae family. it has a variety of purposes and demonstrates antimicrobial and antioxidant properties. this study evaluated the activity of c. cyminum extract and essential oil against bacterial isolates which cause urinary tract infection, i...
