DESIGN-PARAMETRICAL INVESTIGATION OF INVERSE SCATTERING SIGNAL FLUCTUATIONS AT LASER SOUNDING OF EXCITED SEA

The aim is to investigate the influence of the problem parameters and to search the procedures for decrease of the noises. The formulae for autocorrelation function of the echo-signal power, new model of the frequency-contrast characteristics, hardware procedure for decrease of the fluctuations, conditions of the high correlation (>.9) on the depth have been developedAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio

Quality 4.0. Time of revolutionary changes in the QMS

The article examines the tendencies and prospects for constructing adaptive mechanisms for the functioning of active systems, taking into account the influence of the tendencies of the fourth industrial revolution, called “Industry 4.0”, on the quality management system of enterprises. The main components of “Industry 4.0” is the global digitalization of all enterprise processes, including management processes, which makes the process of creating learning mechanisms of functioning (MFF) of active systems, which are able to improve their functioning over time, considered relevant. The described construction of the GFM is based on the use of learning processes carried out using probabilistic iterative (recurrent) algorithms. These algorithms make it possible, as a result of processing current information, to make up for the lack of a priori data and, ultimately, to achieve the best, from a certain point of view, performance indicators

Study of effectiveness of enrofloxacin and moxifloxacin in experimental salmonellosis of chickens

In this publication we present a comparative study of effectiveness of enrofloxacin and moxifloxacin for treatment of chickens, experimentally infected with Salmonella infantis. The chickens received both drugs in water-soluble form via drinking water ad libitum at concentrations of 200 mg/L, 100 mg/L, 50 mg/L and 25 mg/L one day before the challenge and then four consecutive days. The chickens were challenged by intraperitoneal injection with 150 million CFUs of one-day old agar culture of S. infantis in 0.5 mL isotonic saline. The observation period was 15 days. Enrofloxacin proved most effective (88% and 84%) at concentrations of 200 mg/L and 100 mg/L. Lower concentrations caused a decrease in its effectiveness. When enrofloxacin was administered at a concentration of 50 mg/L the survival rate for chickens was 64%. The effectiveness of moxifloxacin in our experiment was considerably lower. The survival rate for chickens, receiving moxifloxacin at concentrations 200 mg/L, 100 mg/L, 50 mg/L and 25 mg/L was respectively 32%, 28%, 32% and 16%, and their average lifespan was half as long as of those groups, receiving enrofloxacin. The results of our research prove the high effectiveness of enrofloxacin at a concentration 200 mg/L in drinking water for the treatment of experimental salmonellosis in chickens
