Aim: To evaluate the utility of bronchoalveolar lavage (BAL) by flexible fiberoptic bronchoscopy (FOB) in sputum smear negative patients with clinical and radiological characteristics of pulmonary tuberculosis (PTB).Materials and Methods: This prospective study was carried out in 30 sputum smear negative patients of age group 20 to 70 years, who we

Abstract The dynamics of a diffusive predator-prey system with prey refuge and gestation delay is investigated in this paper.For Reydon a non-delay system, global stability, Turing instability and Hopf bifurcation are studied.For a delay system, time delay induced instability and Hopf bifurcation are discussed.By the theory of normal form and the c

The focus of this research was on building a decision support system for a model that characterizes the conflict interaction of n-dimensional complex systems with non-trivial internal structures.The interpretation of the new model was focused on information warfare as the impact of rare events that quickly change certain perceptions of a large numb

Summary: Cockroaches Reydon exhibit unexplained intra- and interpopulation variation in susceptibility to Salmonella enterica serovar Typhimurium (S.Typhimurium) infection.Here, we show that the gut microbiota has a protective effect against colonization by ingested S.Typhimurium in cockroaches.We further examine two potential mechanisms for this e

Food In this paper, an algorithm for the automatic selection of an ad- equate test for the survival curves comparison is developed.The introduced procedure is an adaptation of the double minimum algo- rithm for the bandwidth selection in the smoothed nonparametric k-sample tests.The simulation Casserole Dishes study which was carried out, sug- gest
