    Opis:
    Septoria melissae Desm., the most important pathogen of lemon balm (Melissa officinalis) occurs each year on plantations. The fungus may cause serious yield losses in the absence of proper plant protection. Breeding resistant or tolerant cultivars could play an important role in plant protection of medicinal plants. However, only a few descriptions of tolerant varieties of lemon balm are available. The goal of this work was to evaluate the susceptibility of three accessions of M. officinalis against the pathogen of Septoria leaf spot under field conditions at Budapest-Soroksár (Hungary) in 2017–2018. Differences in susceptibility of the accessions were observed in both years. The accession of M. officinalis subsp. altissima proved to be the least susceptible to Septoria infection. The frequency of the infected leaves was only 5.1 and 28.1% in 2017 and 2018, respectively. However, the cultivar M. officinalis subsp. officinalis ‘Lorelei’ turned out to be the most susceptible to the pathogen with an average infection level of 26.1 and 66.6%, 1.3–6.1 times higher than that of the other accessions in each year, respectively. Development of disease tolerant M. officinalis cultivars may be an effective tool in the plant protection of lemon balm.

    Opis:
    Lemon balm (Melissa officinalis L.) is a widely cultivated plant in Europe. Septoria melissae Desm. is the most important pathogen of lemon balm crops, which may cause serious yield loss by the severe leaf fall. As chemical control of the pathogen is restricted, alternative plant protection methods, like the use of tolerant varieties, should be taken under consideration. The goal of our work was to evaluate the susceptibility of three lemon balm varieties to Septoria leaf spot in field. The trials were carried out in 2016 and 2017 in Budapest-Soroksár, Hungary. Dynamics of infection showed characteristic sharp increase from the beginning of August in both years. The lowest infection levels were observed in cultivar ‘Lemona’. The disease incidence in the middle of August was 19% in the first year and 59% in the second year, while these values were over 40% and 70% in the other cultivars ‘Soroksári’ and ‘Quedlinburger Niederliegende’, respectively. The manifestation of symptomps was also significantly lighter on the ‘Lemona’ plants and they had the highest ratio of healthy leaves (81%) compared to the other cultivars. According to the data, weather conditions might modify the range of the differences among the cultivars. It was concluded that appropriate selection of varieties could be an effective and enviromental friendly plant protection method in the practice of lemon balm cultivation.

    Opis:
    Przenośniki są ważnymi elementami systemów przenoszenia materiałów w wielu działach przemysłu, zwłaszcza w przemyśle wydobywczym. Energia elektryczna używana do napędzania przenośników taśmowych w kopalniach odkrywkowych jest istotnym elementem kosztów zakładu górniczego. Dlatego też każdy rodzaj oszczędności uzyskany w tym zakresie skutkuje znaczną i zauważalną obniżką stałych kosztów przedsiębiorstwa [2, 3, 4]. Aby oszczędzać energię elektryczną należy najpierw przeanalizować system napędowy, a następnie zidentyfikować punkty, w których możliwa jest oszczędność energii. Artykuł przedstawia model wspomaganego komputerowo systemu przenośnika taśmowego. Model pracuje z programem EXCEL. Wyniki uzyskane z analizy pracy programu mogą zostać użyte do wspomagania decyzji użytkowników przenośnika taśmowego. Model może być też wykorzystany do celów edukacyjnych.
    In many industries, conveyors are an important part of a material handling system especially in mining industries. Electric power that is used for driving belt conveyors of surface mines is a significant item among the costs of a mining plant [2, 3, 4]. Hence, every saving achieved in this area results in a major and remarkable reduction of the fixed costs for the company. To save electric power the best way is to first examine a driving system and identify the right point of energy saving. The paper deals with the presentation of features of a computer aided model of conveyor belt. The model was developed to run with EXCEL. The results obtained from program running can be used to help making a good decision for the users of conveyor belt. On the other hand it can be used in the education too.

    Opis:
    The aim of this study was to evaluate the serum protein electrophoretic pattern and the concentrations of acute phase proteins (haptoglobin, serum amyloid A, and fibrinogen) in 28 calves with clinical signs of chronic respiratory diseases and 36 healthy calves as a control group. In sick calves we found significantly higher serum concentrations of total proteins (P<0.001), lower concentrations of albumin (P<0.001) and marked shift in the concentrations of the most of protein fractions with significantly higher values of α₁₋, β₁₋, β₂₋, and γ-globulins (P<0.001 and P<0.01). The affected calves had significantly higher values of haptoglobin, serum amyloid A, and fibrinogen as well (P<0.05, P<0.001 and P<0.001, respectively).

    Opis:
    In this study we examined the serum activity of lactate dehydrogenase (LDH) and its isoenzyme patterns in 28 calves of a lowland black spotted breed and its crossbreeds at the age of 2-6 months suffering from clinically noticeable manifested respiratory diseases – bronchopneumonia (BRD Group). As a control group we used 35 clinically healthy calves of the same age, breed and nutrition (Healthy Group). The sick calves did not show clinical signs or pathological lesions on other organ systems. The results found in sick calves showed a significantly higher total activity of LDH than in clinically healthy animals (P<0.01). The mean activity of LDH was 2012 U/l in healthy calves and in calves with respiratory diseases 2529 U/l. The differences in all LDH isoenzyme patterns between both groups of animals were significant (P<0.001) and in calves with respiratory diseases are characterized by a marked increase of the LDH 1 fraction and a decrease in the proportion of the other four LDH isoenzymes. Our results differ from those observed and presented in respiratory diseases in human medicine or in sheep. The explanation for the obtained results in calves and the determination of their diagnostic significance needs further studies and investigations using more animals with various severity of clinical signs and pathological changes, including analysis and determination of lactate dehydrogenase isoenzyme patterns in healthy and affected cattle lung tissue.

    Opis:
    Epidemic outbreaks of avian influenza (AI) virus H5N1 have been frequently reported in Egypt during the last nine years. Here we investigate the involvement of AI H5N1 in outbreaks of acute respiratory disease that occurred in several commercial chicken farms in Egypt in 2011, and we describe to the pathology caused by the virus in the course of the outbreak. Twenty-one chicken farms with history of acute respiratory symptoms and high mortalities were screened for AI H5N1. Virus identification was based on hemagglutination inhibition test, and PCR detection and sequencing of the hemagglutinin and neuraminidase genes. Virus distribution was determined by immunohistochemical staining of AI antigens in organs of infected birds. Standard H&E staining was performed for histological examination of affected organs. Eighty-one % of the examined birds, representing 100% of the screened farms, were positive for AI H5N1 virus. Phylogenetic analysis of the hemagglutinin and neuraminidase genes of the isolated virus reveals its affiliation to clade 2.2.1. Viral antigens were localized in the endothelial cells of the heart, liver, lungs and skin, where pathological lesions including congestion, hemorrhages, multifocal inflammation and necrosis were concurrently observed. According to the pattern of the viral antigen and lesion distribution in the visceral organs, we suggest cardiovascular and circulatory failures as the probable cause of death during these outbreaks. In conclusion, the present study further confirms the epidemic status of AI H5N1 virus in Egypt and reveals the highly pathogenic nature of the local isolates.
