Wraz z upływającym czasem zmienia się również krajobraz wiejski i jego przestrzeń , dotychczasowy sposób uprawy ziemi oraz formy zagospodarowania terenów jak i towarzysząca temu niezbędna infrastruktura techniczna. Wśród ludności zamieszkującej te obszary następuje szereg społecznych przemian, w wyniku czego pojawiają się dążenia do efektywniejszego wykorzystania potencjału zasiedlonych terenów. Pro-blematyką wiejską zajmuje się szereg dyscyplin, z których każda w innym ujęciu omawia zachodzące przemiany. Szerokie i interdyscyplinarne spojrzenie na zachodzącą ewolucję w przestrzeni wiejskiej jest możliwe poprzez analizę krajobrazu kulturowego danego regionu, obserwację zmian następujących w zagospodarowaniu przestrzennym i architekturze. Niezmienny jest fakt, iż celem rolnictwa jest wytwarzanie płodów rolnych, jednakże różnorodność upraw oraz sposób ich doboru jak i formy uprawy, wraz z zagospodaro

The aim of the study was to investigate the influence of sand bed moisture on TNT transport from under the sand layer. The MO-2M explosive vapor detector was used, the detection mechanism of which is based on the FAIMS method. In addition, it was determined after what time the detector alarm appears, signaling the presence of TNT vapors, and how it affects the thickness of the sand layer. The performed work allowed us to assess the suitability and possibly adapt the MO-2M detector to detect non-metal mines, which will help develop new application possibilities for this device. These tests can also be used to eliminate environmental contamination resulting from the deposition of explosives in the ground and the migration of harmful compounds to groundwater.

The current practice in securing the contact traces of chemical substances taken from clothes belonging to a person suspected of manual handling explosives is focused on pockets and cuffs. The outerwear worn by people who had contact with fluorescent powders that simulate explosives and drugs was the subject of this study. Clothes were first exposed to the test substance for a period of time and then analyzed by fluorescence methods to determine the location of the highest quantity of traces. The results obtained from the study confirm that the areas with the highest concentration of powdery traces are different from those suggested by current forensic practice. They appear to be promising for a more efficient identification of the suspects involved in illegal manufacturing of drugs of abuse or explosives. Moreover, they may be helpful for developing the methodology for handling the evidence material in the forensic clothing examination process.

Differential scanning calorimetry (DSC) and infrared spectroscopy (FT-IR) techniques were applied to analyze polymer type and its content in wood-plastic composites (WPC). Methods of analysis were developed on the basis of commercial and laboratory made WPC samples with different content of polypropylene (PP) and high-density polyethylene (HDPE). Polymer melting temperature was used to determine its type and melting enthalpy value was used to determine polymer content in the sample. The method was rewarding, both in qualitative and quantitative way. The absorption bands from FT-IR spectra (1508 cm-1 , i.e., aromatic skeletal vibration of lignin and 1455 cm-1 , i.e., CH 2 bending for polypropylene) were chosen to determine polymer content. Calibration curve obtained on the basis of measurements made on laboratory prepared samples with different polymer content was elaborated. Determination of polymer type with FT-IR was unequivocal, while determination of its content may cause troubles in case of samples with lower polymer content.
