Opis:
Perennial energy crops are a source of the biomass used to generate energy. The aim of this study was to determine the chemical and thermophysical parameters of short rotation woody crops (black locust, poplar and willow), depending on soil enrichment practice (mineral fertilisation, lignin and mycorrhiza), in three- and four-year harvest cycles. In the study, the thermophysical properties and elemental composition of the biomass were determined. All analyses were performed in triplicate according to the standards. The fresh black locust biomass had the lowest moisture content, which resulted in the best lower heating value (10.16 MJ kg-1, on average) in the four-year harvest cycle. The poplar biomass had the greatest higher heating value, fixed carbon, carbon and ash content, the highest concentrations of which were found in the biomass in which lignin was applied (2.00% d.m.). On the other hand, the willow biomass contained the lowest concentrations of ash and fixed carbon. Soil enrichment significantly differentiated the quality parameters of black locust, poplar and willow. This effect is of particular importance to those who grow and use biomass as a fuel.

Opis:
The aim of this study was to determine the influence of nitrogen fertilization and the preceding crop on the yield and chemical composition of winter oilseed rape. The yield of winter oilseed rape increased significantly in response to a fertilizer dose of 180 kg N ha-1. In our study, significant interactions were observed between the preceding crop and dose of nitrogen fertilizer. The optimal N fertilizer dose for winter oilseed rape grown after peas, narrow-leaved lupine and traditional (indeterminate) faba beans is 120 kg N ha-1. The recommended N fertilizer dose for winter oilseed rape is 60 kg N∙ha-1 after determinate faba beans and 180 kg N ha-1 after spring wheat. Winter oilseed rape was characterized by the highest seed yield when grown after determinate faba beans, and its yield was slightly lower after peas and narrow-leaved lupine. The lowest seed yield was noted when spring wheat was the preceding crop. The micronutrient content (Mn, Zn, Cu and Fe) of winter oilseed rape increased significantly in response to an increase in nitrogen fertilization doses. The seeds of winter oilseed rape were characterized by the highest phosphorus and magnesium content when grown after peas, the highest potassium content was achieved after determinate faba beans, and the highest calcium content occurrd in oilseed ape when grown after spring wheat. A linear regression analysis revealed a significant relationship between total nitrogen concentrations in the seeds of winter oilseed rape growth after spring wheat and nitrogen fertilization dose. An increase in fertilization levels enhanced nitrogen accumulation in seeds. A similar trend was noted when winter oilseed rape was grown after indeterminate faba beans and peas.

Introduction. The paper is a case report presenting Cat Scratch Disease (CSD) in a 1.5-year- old girl. Bartoneloses, including CSD, are a group of infectious diseases which are rarely detected, therefore there are no statistical data concerning the aetiology, and the incidence of CSD noted in Poland is low in comparison with other European countries. Objective. The purpose of the paper is to discuss several problems related to CSD. Materials and method. A 1.5-year-old girl who was seen in hospital for the sparing use of her left arm when crawling. X-rays showed osteolytic lesions which radiologists described as multi-ocular cyst or infection. As neither clinical examination nor laboratory investigations found pathological signs, the patient was followed-up on an ambulant basis. Repeated x-ray taken 4 weeks later showed increased periosteal proliferation accompanied by pain. The baby was admitted to the Clinic but additional investigations found no pathologies. The baby was consulted by a rheumatologist and haematologist; however, they did not facilitate a definitive diagnosis. As the baby developed, because of a thickening of the soft tissues on the dorsal side of the distal epiphisis in the forearm the doctors decided to inspect the condition operatively. Macroscopic examination found brownish granulated tissue. Suction drainage was inserted and a tissue sample was tested for aerobic and anaerobic bacteria, tuberculosis and borelliosis. The test results were negative. The baby was in good condition, was not pyrexial and suffered from less pain. The diagnostics was further expanded and the baby tested for yersinia, chlamydia, tuberculosis and bartonella, i.e. CSD. The postoperative wound healed soon and radiological bony lesions began to resolve. After a month, we received a positive bartonella test result, the baby tested positively for Bartonella henselae IgG class, which confirmed past or active infection of CSD. A repeated test for B. henselae taken 6 months later showed a lower level of antibodies. Conclusions. It should be remembered that CSD, which is an extremely rare infection, can be diagnosed despite mediocre clinical and radiological manifestations. Thus, in the case of infections of unexplained aetiology and mediocre manifestations diagnostics should include testing for Bartonella henselae.
