Qualifying types represent a new approach to modifying the behaviour of instances of other types in a general way, in the form of components which can be designed and implemented without a prior knowledge of the types to be modified or their implementations. This paper illustrates the idea by showing how they can be used to program various standard synchronisation problems, including mutual exc...
Industry cluster and supply chain are in focus of every countries which rely on knowledge-based economy. Both focus on improving the competitiveness of firm in the industry in the different aspect. This paper tries to illustrate how the industry cluster can increase the supply chain performance. Then, the proposed methodology concentrates on the collaboration and knowledge exchange in supply ch...
Background: Excessive use of antibiotics and biocides has led to emergence of resistant Staphylococcal strains. The aim of this study was to examine resistance of Staphylococcal strains biofilm isolated to biocidal components. Methods: 100 clinical isolates of Staphylococcus aureus were collected from hospitalized patients with infectious skins from two Shohadaye Tajrish and Valiasr ho...
Background and Aims: Microbial biofilms are responsible for 65% of human infections and antibiotic resistance. Therefore, finding appropriate ways to prevent infection and biofilm formation is essential. Medicinal plants are one of the suitable candidates to inhibit the antibiotics resistance particularly in biofilm forms. In this study, antimicrobial effects of T.C.P combined extracts (methano...
Background: Acinetobacter baumannii is commonly resistant to nearly all antibiotics due to presence of antibiotic resistance genes and biofilm formation. In this study we determined the presence of certain antibiotic-resistance genes associated with biofilm production and the influence of low iron concentration on expression of the biofilm-associated protein gene (bap) in development of biofilm...
Introduction: Although bacteria producing biofilm are more resistance to antimicrobial agents, biofilm formation can stimulated by sub-minimal inhibitory concentrations (sub-MICs) of some antimicrobial agents. Therefore, we designed present study to investigate the in vitro efficacy of several antibiotics (including ceftazidime, piperacillin, ticarcillin, carbenicillin, aztreonam, merop...
conclusions the findings of the present study well demonstrated that the p. aeruginosa biofilm-producing isolates were more resistant to the tested antibiotics. furthermore, because of wide distribution, it seems that the psla gene is associated with biofilm formation. results biofilm formation was observed in 70% of the p. aeruginosa isolates. the potential formation of biofilm was significant...
objective(s) methicillin-resistant staphylococcus aureus (mrsa) is an important cause of nosocomial and community infections. biofilm formation, mediated by a polysaccharide intercellular adhesin (pia) and encoded by the ica operon, is considered to be an important virulence factor in both s. epidermidis and s. aureus. however, the clinical impact of the ica locus and pia production is less wel...
یکی از چالش های عمده بخش کشاورزی در کشور های در حال توسعه، سوق دادن کشاورزی به سمت تولید برای بازار یا مشارکت کشاورزان در بازار محصولات کشاورزی می باشد. الگوی تولید حاکم در این کشورها به گونه ای است که بسیاری از آنان در مزارع به منظور تامین معیشت و به صورت خود مصرفی تولید می کنند و تعداد معدودی از آنها وارد بازار می شوند. لذا، در مطالعه حاضر تاثیر هزینه های مبادله بر رفتار و نحوه مشارکت تولید ک...
