Opis:
Newcastle disease (ND) is a highly contagious and devastating viral disease of poultry and other birds that has a worldwide distribution. ND in pigeons is called paramyxovirosis and is caused by antigenic “pigeon variant” of the virus (pigeon paramyxovirus type 1, PPMV-1). During PPMV-1 infections, central nervous system symptoms and sometimes high mortality are observed. In the case of infection with viscerotropic strains which exhibit specific affinity for the kidneys, the first observed sign is polyuria, and neural symptoms appear only in individual birds in the flock. Due to the similarity of symptoms of paramyxovirosis to the pigeon herpes virus infection (PHV), sodium chloride poisoning, overdose of ronidazole or vitamin B1 deficiency, it is necessary to perform laboratory tests to make a correct diagnosis. After virus isolation PPMV-1 can be detected initially by haemagglutination assay (HA). PPMV-1 can be confirmed by conventional serological tests such a haemagglutination inhibition test (HI) or molecular-based techniques. In the prophylaxis of paramyxovirosis in pigeons, inactivated vaccines are used, administered by subcutaneous injection in various prevention programs. However, vaccination should be only one component of a strategy of PPMV-1 control, on a par with effective biosecurity and proper, effective methods of prevention and diagnostics of paramyxovirosis.

Opis:
The present study investigated the prevalence of Bordetella avium (BA) infections in turkey flocks of different production type in Poland, based on serological examination of blood samples collected between 2012 and 2014. The results of our study indicate that BA infections are very common in turkey flocks, they are possible during the whole production cycle and that probability of the past infection increases with age. This situation is causing high level of specific anti-BA maternally derived antibody transfer to hatching poults.

Opis:
The objective of this study was to determine the effect of whole wheat feeding on selected parameters of humoral and cell-mediated immunity in growing turkeys. A total of 210 one-day-old heavy-type Hybrid Converter male turkeys were randomly divided into three different dietary treatment groups, each consisting of 7 replicate pens of 10 birds per pen. Until 4 wk of age, all birds were fed a commercial diet formulated to meet nutrient requirements. From 5 to 12 wk of age, diets were composed of wheat (ground-pelleted or whole grain) and protein-fat-mineral-vitamin concentrate. The total wheat concentration in diets was 500 or 600 g/kg in the feeding periods of 5-8 and 9-12 wk of birds’ age, respectively. Whole grain wheat had a 0, 50 or 100% share of the total wheat amount in the daily ration in treatment groups W₀, W₅₀ or W₁₀₀, respectively. Commercial vaccines against ND (Newcastle disease) and TRT (Turkey rhinotracheitis) were administered to turkeys via the drinking water on days 20 and 30, respectively. Over the entire experiment, a significant linear decrease was observed in body weight gains (BWG) with increasing dietary levels of whole grain wheat. As a result the BWG of control turkeys (W₀) were significantly higher than the BWG of group W₁₀₀ birds (P = 0.002). A significant linear increase in feed conversion ratio (FCR) was observed with increasing dietary levels of whole grain wheat (P < 0.001). The levels of antibodies against TRT and ND viruses after immunization were significantly higher in both the W₅₀ and W₁₀₀ group, in comparison to group W₀ (P = 0.006 and P = 0.001, respectively). Turkeys from group W₅₀, in comparison to those from groups W₀ and W₁₀₀, had a significantly higher percentage of CD4⁺ T cell subpopulation within the lymphocytes isolated from blood and ileal mucosa, as well as CD4⁺ CD8⁺ and CD8⁺ T cell subpopulations within the blood immunocompetent cells (P = 0.022, P = 0.029, P = 0.009 and P = 0.011, respectively). In the cecal tonsils, the percentage of CD8⁺ T cell subpopulation was significantly lower in group W₅₀ than in groups W₀ and W₁₀₀ (P = 0.014). The results of our study indicate that diluting diets with whole grain wheat stimulates the non-specific cell-mediated defense mechanisms of the gastrointestinal immune system in turkeys, thus positively affecting humoral response after vaccination.

Opis:
Bordetella avium, the causing agent of bordetellosis, a highly contagious infection of the respiratory tract in young poultry, causes significant losses in poultry farming throughout the world. Wildlife birds can be a reservoir of various pathogens that infect farm animals. For this reason the studies were conducted to estimate the prevalence of Bordetella avium in wildlife birds in Poland. Tracheal swab samples were collected from 650 birds representing 27 species. The bacterial DNA was isolated directly from the swabs and screened for Bordetella avium by TaqMan real-time PCR. The assay specificity was evaluated by testing DNA isolated from 8 other bacteria that can be present in avian respiratory tract, and there was no amplification from non-Bordetella avium agents. Test sensitivity was determined by preparing standard tenfold serial dilutions of DNA isolated from positive control. The assay revealed to be sensitive, with detection limit of approximately 4.07x10^2 copies of Bordetella avium DNA. The genetic material of Bordetella avium was found in 54.54% of common pheasants, in 9.09% of Eurasian coots, in 3.22% of black-headed gulls and in 2.77% of mallard ducks. The results of this study point to low prevalence of Bordetella avium infections in wildlife birds. The results also show that described molecular assay proved to be suitable for the rapid diagnosis of bordetellosis in the routine diagnostic laboratory.

Opis:
Maternally derived antibodies (MDA) don not protect turkeys against rhinotracheitis (TRT) but high MDA influences upper respiratory tract (URT) immunity stimulation after avian Metapneumovirus (aMPV) vaccination. Humoral immunity can not be considered as an indicator of protection against TRT, but specific antibodies inhibit aMPV replication and alleviate the course of TRT. Scarce reports indicate the role of IgA in protection against TRT. The aim of our study was to investigate the impact of MDA on stimulation, antigen specificity acquisition of B lymphocytes, and the production of specific IgA after TRT vaccination of turkeys. The results of our study indicate that MDA on the day of TRT vaccination causes disturbances at different levels of specific humoral immunity expression including antigen specificity acquisition of B IgA+ lymphocytes as well as production and secretion of IgA. Vaccine immunity against aMPV associated with sIgA is well expressed in birds not possessing MDA on the day of TRT vaccination, whereas it is inhibited in MDA+ birds. These results corroborate our previous findings and indicate that MDA could be responsible for TRT vaccination failure. These findings could explain the observed frequency of TRT field outbreaks despite aMPV vaccination of turkey flocks.

Opis:
The aim of the study was to determine the effect of a Polish low-virulence isolate of haemorrhagic enteritis adenovirus (HEV) on the immune system in turkeys and on the course of colibacillosis in birds infected under laboratory conditions. Turkeys were infected per os with HEV at the dose of 104.3EID50/mL and with E. coli (APEC) (serotypes 078:K80:H9) at the dose of 4×109CFU/mL by injection to the thoracic air sac. The birds infected with the HEV were infected with the APEC either simultaneously or after 5 days. Five days after HEV infection, the percentages of subpopulations of the CD3+CD4+ and CD3+CD8α+ T cells and the IgM+ B cells were determined in blood and spleens of the HEV-infected turkeys and in the control (uninfected) birds. The course of colibacillosis was more severe in turkeys infected with the APEC 5 days after infection with the HEV than in those infected with the HEV and APEC simultaneously and than in those infected only with APEC. Five turkeys out of the 18 infected with the APEC 5 days after infection with HEV, died. Their body weights were statistically significantly lower with higher FCR values 41 days after the infection in comparison to turkeys in the other groups. A considerable decrease in the percentage of the T and B cells subpopulations in the blood were found in turkeys infected with the HEV and while the percentage of CD3+CD4+ T cells subpopulation in the spleen increased significantly, the contribution of the CD3+CD8α+ T cells and IgM+ B cells subpopulations were decreased. These changes in the immune system of turkeys, occurring 5 days after infection with the HEV, made them more susceptible to infection with the APEC.

Opis:
Biomass is one of the renewable energy sources that could replace conventional carbonaceous fuels. The remains of timber industry or the agro-food sector are attractive sources of biomass taking into account environmental and economic aspects. Stones of fruits such as cherries, peaches or apricots can be converted into heat in the combustion processes. They can also be converted into liquid or gas biofuels in a gasification and pyrolysis processes. The aim of the study was to determine the higher (HHV) and lower heating value (LHV) of cherry stones and to determine their energy potential in Polish market of renewable energy. Relative humidity of dried cherry stones was 5.80±0.12% and ash content was equal to 1.43±0.04%. The higher heating value of crushed cherry stones was 20.6±0.7 MJ·kg-1, while the lower heating value 19.2±0.8 MJ·kg-1. The theoretical share of thermal energy from combustion cherry stones in the national heat production from renewable energy sources amounted to 0.42% in 2013.
Jednym ze źródeł energii odnawialnej, mogącym zastąpić tradycyjne paliwa węglowe, jest biomasa. Atrakcyjnym ze względu na aspekt środowiskowy i ekonomiczny źródłem biomasy są pozostałości przemysłu drzewnego lub rolno-spożywczego. Pestki owoców takich jak wiśnie, brzoskwinie lub morele mogą być przetworzone w energię w procesach bezpośredniego spalania lub współspalania. Można je również poddać procesom pirolizy lub zgazowywania i otrzymać biopaliwa ciekłe i gazowe. Celem pracy było określenie ciepła spalania i wartości opałowej pestek wiśni oraz określenie ich potencjału energetycznego w warunkach krajowych. Wilgotność względna suszonej pestki wiśni wynosiła 5,80±0,12%, a zawartość popiołu 1,43±0,04%. Średnie ciepło spalania rozdrobnionych pestek wiśni było równe 20,6±0,7 MJ·kg-1, natomiast wartość opałowa 19,2±0,8 MJ·kg-1. Teoretyczny udział energii cieplnej pochodzącej ze spalania pestek wiśni w krajowej produkcji ciepła z odnawialnych nośników energii wynosił 0,42% w 2013 roku.

Opis:
In the future International Thermonuclear Experimental Reactor (ITER), the interaction between the plasma and the tungsten chosen as the plasma-facing wall material imposes that the hot central plasma loses energy by X-ray emission from tungsten ions. On the other hand, the registered X-ray spectra provide alternative diagnostics of the plasma itself. Highly ionized tungsten emits extremely complex X-ray spectra that can be understood only after exhaustive theoretical studies. The detailed analyses will be useful for proper interpretation of soft X-ray plasma radiation expected to be registered on ITER-like machines, that is, Tungsten (W) Environment in Steady-state Tokamak (WEST). The simulations of the soft X-ray spectra structures for tungsten ions have been performed using the flexible atomic code (FAC) package within the framework of collisional-radiative (CR) model approach for electron temperatures and densities relevant to WEST tokamak.

Opis:
In the following article a discussion on the use of e-learning in education of convicts is presented. The topic discussed by the Author is connected with the fact that the use of new media in education at present has become a common solution applied also to educate inmates. E-learning is a current form of education andvocational training. It provides improvement of contemporary culture in education applied at penitentiary institutions to educate convicts. E-learning helps and lets prisoners obtain education and to update education differences. As a method of education, it requires users’ autonomy and self-discipline while working with the use of digital platforms. Education must respond to different needs expressed by the evolving knowledge society. It mainly concerns education of people at risk of social exclusion, e.g. convicts. It is related to the need of dealing with and solving problems that pertain to such issues as increasing possibilities of the media in the area of generating, processing and creating information. The aim of the article is also to describe the use of e-learning in European countries such as Sweden, Norway, Poland, Finland and Germany. These countries were selected for the analysis because they appreciate modern technologies in penitentiary work. They change and develop the solutions. The experience in the use of e-learning in penitentiary work with inmates in Sweden, Norway, Poland, Finland and Germany is different. The aim of the article is also to show how modern technology can be applied in working with convicts. E-learning becomes a tool used for preventing exclusion. Development of various technologies makes it possible to support convicts and prison staff members in the process involving correctional activities. Technologies offer a chance to return or to start work, to continue education, to meet the needs of one’s family, to have an active life in accordance with the social principles after leaving prison. E-learning provides people who have been isolated in prison with a real chance to acquire qualifications. Hence, social issues, family interests, individual interests, business and modern technological solutions are combined in the same field. Coherent and efficient activities come as a challenge to those who perform them and to the society; however, these activities support the process of social rehabilitation.
W poniższym artykule przedstawiono dyskusję na temat wykorzystania e-learningu w edukacji skazanych. Temat poruszany przez Autorkę wiąże się z faktem, że wykorzystanie nowych mediów w edukacji stało się obecnie powszechnym rozwiązaniem stosowanym także w edukacji osadzonych. E-learning to aktualna forma edukacji i szkolenia zawodowego. Zapewnia doskonalenie współczesnej aktywności w edukacji stosowanej w zakładach penitencjarnych do kształcenia skazanych. E-learning pomaga i umożliwia osadzonym zdobywanie wykształcenia oraz aktualizowanie różnic edukacyjnych. Jako metoda edukacji wymaga autonomii i samodyscypliny użytkowników podczas pracy z wykorzystaniem platform cyfrowych. Edukacja musi odpowiadać na różne potrzeby wyrażane przez rozwijające się społeczeństwo wiedzy. Dotyczy to głównie edukacji osób zagrożonych wykluczeniem społecznym, m.in. skazanych. Wiąże się to z potrzebą radzenia sobie i rozwiązywania problemów, które dotyczą m.in. zwiększania możliwości mediów w zakresie generowania, przetwarzania i tworzenia informacji. Celem tekstu jest opis wykorzystania e-learningu w uczeniu się osób osadzonych na przykładzie wybranych państw europejskich takich jak Szwecja, Norwegia, Polska, Finlandia czy Niemcy. Kraje te zostały wybrane, ponieważ doceniają nowoczesne technologie w pracy penitencjarnej. Zmieniają i rozwijają rozwiązania. Doświadczenia w wykorzystaniu e-learningu w pracy penitencjarnej z osadzonymi w Szwecji, Norwegii, Polsce, Finlandii i Niemczech są różne. Celem jest również pokazanie, jak nowoczesna technologia może być wykorzystana w pracy ze skazanymi. E-learning staje się narzędziem przeciwdziałającym wykluczeniu. Rozwój technologii pozwala na wspieranie osadzonych i kadry jednostek w prowadzonym procesie działań korekcyjnych. Technologie dają szansę na powrót bądź rozpoczęcie pracy, kontynuowanie nauki, zaspokojenie potrzeb rodziny, aktywne życie zgodnie z zasadami życia społecznego po opuszczeniu jednostki. E-learning stwarza realną szansę na zdobycie kwalifikacji osobom pozostającym w warunkach izolacji. Łączą się w jednym obszarze kwestie społeczne, interesy rodziny, jednostki, biznes i nowoczesne rozwiązania technologiczne. Spójne i skuteczne działania są wyzwaniem dla ich realizatorów i społeczeństwa ale także wspierają proces resocjalizacji.
