Opis:
The purpose of this work is to develop a model for implementing an effective and efficient Continuous Improvement projects, aimed at increasing the performance of production processes. In particular, it aims to innovate in the way of deploying a Program Improvement in the company to make this process run as efficiently as possible. Although continuous improvement programs are some of the tools that are commonly used in industrial environments to increase the performance of their processes, it has become clear that there is a need to develop a continuous improvement model that will be implemented efficiently, and its results will remain over time. Also, it has been found that the model mentioned previously should serve to develop the foundations of an Organization which learns quickly and continuously.

Opis:
The Erwinia species are well-known pathogens of economic importance in Malaysia causing serious damage to high-value fruit crops that include pineapple [Ananas comosus (L.) Merr.] and papaya (Carica papaya L.).The 16S rRNA sequence using eubacteria fD1 and rP2 primers, identified two bacteria species; Dickeya zeae from pineapple heart rot, and Erwinia mallotivora from papaya dieback. Phylogenetic analysis based on the neighbor-joining method indicated that all the bacterial isolates clustered in their own taxa and formed monophyletic clades. From the pathogenicity test, all isolates of D. zeae and E. mallotivora showed pathogenic reactions on their respective host plants. Genetic variability of these isolates was assessed using repetitive sequence-based PCR (rep-PCR) fingerprinting. The results indicated interspecies, and intraspecies variation in both species’ isolates. There were more polymorphic bands shown by rep-PCR fingerprints than enterobacterial repetitive intergenic consensus (ERIC) and BOX- PCRs, however both species’ isolates produced distinguishable banding patterns. Unweighted pair-group method with arithmetic averages (UPGMA) cluster analysis indicated that all Dickeya and Erwinia isolates from the same species were grouped in the same main cluster. Similarity among the isolates ranged from 77 to 99%. Sequencing of 16S rRNA using eubacteria fD1 and rP2 primers, and rep-PCR fingerprinting revealed diversity among Dickeya and Erwinia isolates. But this method appears to be reliable for discriminating isolates from pineapple heart rot and papaya dieback.

Opis:
The coexistence of anti-synchronization and synchronization in chaotic systems is investigated. A novel algorithm is proposed to determine the variables of the master system that should anti-synchronize with corresponding variables of the slave system. Control strategies that guarantee the coexistence of synchronization and anti-synchronization in the unified chaotic system are presented; while numerical simulations are employed to validate and illustrate the effectiveness of the proposed method.

Opis:
The aim of the study was to assess the effect of selected isolation methods on the viability and metabolism of bovine leukocytes. The cells were isolated using a Ficoll 1077, Histopaque 1083 gradient and osmotic shock method, and Ficoll or Histopaque with osmotic shock. Evaluation were made of the total number of cells, viability after isolation and in 24h culture on RPMI 1640 medium and metabolism with NBT reduction assay. Microscopic and cytometric evaluation of the leukocytes revealed that the isolation methods applied had an influence on their number and viability. Based on the results it can be concluded that isolation methods of cells in a Histopaque or Ficoll yield highly pure cell fractions with high viability.

Opis:
Electroencephalography (EEG) has been reported as an objective, non-invasive and stress free technique for nociceptive studies. Electrical stimuli can be used to evaluate the efficacy of centrally acting agents. Peripheral nerve stimulator can be a good and cheap source of electric stimulus for studies of nociception, and studies evaluating analgesic effect of drugs under EEG. In this study suitability of peripheral nerve stimulator, and milliamperage for nociceptive studies under electroencephalography were evaluated. Six dogs were subjected to electric stimulus of 20, 40, 60 and 80 milliamperes (mAs) before and after tramadol administration at 4 mg/kg IV. Electroencephalograph was recorded during electric stimulus prior tramadol (pre-tramadol) and during electric stimulus after tramadol (post-tramadol) under minimal anaesthesia. Anaesthesia was induced with propofol and maintained with halothane at a stable concentration between 0.85 and 0.95%. Pre-tramadol median frequency (MF) increased significantly (p<0.05) at 40, 60 and 80 mAs post-electric stimulus compared to baseline MF. No difference in pre-tramadol MF was observed between 60 and 80 mAs. Tramadol produced significant effect by depression of MF at all intensities. The effect was less evident at 80 mAs. The results revealed that tramadol produced evident effect between 20 and 60 mAs. Thus, it is concluded that nerve stimulator can be used with the current between 20 and 60 mAs for nociceptive studies.

Opis:
The concerned paper presents results of wide scope of liquid steel filtering tests by means of ceramic filters, including laboratory, model and industrial testing in the conditions of conventional (ingot) and continuous steel casting. Multi- hole (sieve) ceramic filters made of mullite and corundum, of the structure adjusted to the type of conducted experiment were used for testing. Selection of ceramic material for filter construction accounted for the conditions of filter operations including: high temperature (liquid steel temperature), filtering duration determined by mass of the filtered steel, hydrodynamics of steel flow through filter holes an and wettablity of filter ceramics by non-metallic inclusions. In order to assess the effectiveness of liquid steel filtering in reference to unfiltered steel, the following criteria have been adopted: - change in surface share of non-metallic inclusions, - change in the quantity of non -metallic inclusions and dimensions thereof, - change in total oxygen content (summary). The obtained results of tests confirm high effectiveness of liquid steel filtering by means of ceramic filters and may constitute a basis for development of a new technology of steel refining by means of filtration.
prezentowanej pracy przedstawiono wyniki szerokiego zakresu badań procesu filtracji ciekłej stali filtrami ceramicznymi, obejmującego badania laboratoryjne, modelowe i przemysłowe w warunkach konwencjonalnego (do wlewnic) i ciągłego odlewania stali. W badaniach stosowano filtry ceramiczne wielootworowe (sitkowe) wykonane z mulitu i korundu o konstrukcji dostosowanej do rodzaju prowadzonego eksperymentu. Wybór tworzywa ceramicznego do budowy filtrów uwzględniałwarunki pracy filtra do których zaliczano: wysoką temperaturę (temperaturę ciekłej stali), czas filtrowania określony masą filtrowanej stali, hydrodynamikę przepływu stali przez otwory filtra oraz zjawisko zwilżalności ceramiki filtra przez ciekłe wtrącenia niemetaliczne. Dla oceny skuteczności procesu filtrowania ciekłej stali w odniesieniu do stali niefiltrowanej, przyjęto następujące kryteria: - zmianę udziału powierzchniowego wtrąceń niemetalicznych, - zmianę liczby wtrąceń niemetalicznych i ich wymiar, - zmianę zawartości tlenu całkowitego (sumarycznego). Uzyskane wyniki badań świadczą o dużej skuteczności metody filtrowania ciekłej stali filtrami ceramicznymi i mogą stanowić podstawę do opracowania nowej technologii rafinacji stali metodą filtracji.
