Food adulteration means that substances have been added to food that change its composition and reduce its nutritional value. Food adulteration also includes giving a product a misleading name, providing false information on its composition, date of production or expiry date, and any other incorrect labelling. Numerous cases of food adulteration have been recorded in many countries, including Poland. This has led to the creation of a new field of science, known as ‘green criminology’, to combat violations of food law. Over the years, new techniques for identifying food adulterations have been developed. Originally, these were sensory techniques, which proved unreliable. Later, physical analysis of the product was performed on the basis of information on the label and microscopic examination. Later methods, based on identification of lipids and proteins, were also unreliable due to biochemical changes during processing. These problems prompted scientists to become interested in the potential of DNA testing. Due the stability of DNA and the universal applicability of DNA-based methods to all cells, they are ideal for use in practice. Currently, the most reliable test for detecting food adulteration is PCR, as it is a highly sensitive and specific technique.

Wprowadzenie. Współcześnie ponad 60% polskich internautów korzysta z Internetu w celu poszukiwania treści dotyczących zdrowia i choroby. Najliczniejszą grupę z tej społeczności stanowią studenci. Coraz częściej wykorzystują oni uzyskane z zasobów sieci internetowej informacje, aby samodzielnie diagnozować schorzenia i podejmować próby ich leczenia. To narastające zjawisko potwierdza, że obecnie w opiece zdrowotnej następuje przejście od modelu paternalistycznego do modelu współpodejmowania decyzji, w którym pacjent staje się w pełni świadomym i wyedukowanych uczestnikiem procesu terapeutycznego. Cel pracy. Celem pracy jest ocena wykorzystania Internetu jako źródła informacji o zdrowiu, a także chorobach i metodach ich leczenia wśród lubelskiej społeczności studenckiej. Materiał i metoda. Badanie ankietowe przeprowadzone zostało w maju 2012 r. wśród studentów uczelni lubelskich: Uniwersytetu Medycznego, Uniwersytetu Marii Curie-Skłodowskiej, Uniwersytetu Przyrodniczego oraz Politechniki Lubelskiej. Anonimowy kwestionariusz ankiety zawierał 14 pytań (w tym 1 otwarte). Wyniki. Otrzymane wyniki potwierdzają, że Internet jest obecnie pierwszym źródłem informacji o zdrowiu i chorobie dla 59% badanych. Respondenci najczęściej korzystają z serwisów medycznych (64%), a także portali społecznościowych i forów dyskusyjnych (55,3%). Wnioski. Studenci w celu odnajdywania treści z obszaru medycyny chętnie korzystają z Internetu, co wynika z łatwego i szybkiego dostępu do niego. Młodzi ludzie głównie szukają informacji o objawach i formach leczenia, co przekłada się na wzrost tendencji do podejmowania samodiagnozy i samoleczenia.

The aim of this study was to evaluate the fit of mathematical models for drying wet wood chunks with a length of 60 ±1 mm and a diameter of 10 ±2 mm and dry wood chips size of 40 ±10 mm obtained from the branches of fruit trees stored for a 6--months period under natural conditions. Biomass moisture was measured on a monthly basis. For moisture ratio the parameters of nine mathematical models and their statistical evaluation were developed. It was found that wet wood chunks had a large shrinkage (15%) which was probably due to the high content of soft wood tissue in the branches. During the storage of wet wood chunks the moisture decreased significantly, from 47.57 to 10.84%, and the dry chips only slightly (from 11.85 to 8.04%), and in both cases at the end of drying the biomass reached an equilibrium moisture. The best model reflecting changes moisture ratio of wet wood chunks is the Page's model, but the Wang's, Singh's and logarithmic models, may also be used for drying a moist biomass under natural conditions. Drying of dry wood chips is best represented by the logarithmic model, but for this kind of material a Page's, Wang's and Singh's, two term and Midilli's et al. models can be used. Modeling in natural conditions requires consideration of ambient conditions, especially air temperature and relative humidity.

An autopsy or necropsy can be performed only once; therefore, its proper execution is of fundamental importance in explaining the cause of death. The protocol with photographic documentation is an integral part of the autopsy, but sometimes it does not fully reflect the state of the body and the pathological changes observed at each stage of the procedure. These shortcomings are addressed by modern imaging techniques, which are increasingly used during the autopsy of human bodies, but quite rarely during necropsy of animals. Non-invasive techniques (CT, MRI, or photogrammetry with laser body scanning), or in some cases also minimally invasive techniques (biopsy), enable comprehensive analysis of the carcass, but Virtopsy is only a supplement to the classical autopsy, especially in veterinary forensic medicine.

At present, the most common method of analysis of gunshot wounds is necropsy, but modern imaging methods, such as X-ray (RTG) and computed tomography (CT), are gaining in popularity. We conducted an experiment involving shooting at test material from various distances (0 m, 1.5 m, 15 m) with bullets of various calibres in order to obtain characteristic gunshot wounds and compare the utility of the traditional autopsy method and modern imaging methods for forensic veterinary purposes. Then, a digital X-ray and computed tomography scan as well as a necropsy, were performed. The analysis of the results of the experiment with ammunition of different calibres showed that damage caused by a shot from a firearm is correlated with the calibre, initial velocity and kinetic energy of the projectile, as well as the distance from the barrel end to the object being shot. In the 12 cases analysed, 80% of the bullets fired from different distances had sufficient kinetic energy to exit the test material after passing through the tissue. A macroscopic necropsy supplemented by modern imaging methods is the most accurate means of forensic veterinary analysis of gunshot wounds in animals.
