Opis:
The objective of this study was to evaluate the risk of soil transmitted zoonotic helminth infections for families with young children, inhabitants of villages in the Mazowieckie Province of Central Poland. Epidemiological survey was conducted at 33 randomly selected households with 2–3 children present. Examination of soil samples from yards surrounding the houses for the presence of geohelminth eggs was conducted, the households were inspected, and family members interviewed using a designed questionnaire. Among 55 localities examined, i.e. 33 backyards, 10 vegetable gardens and 12 sandpits, contamination was found in 2 backyards (6.1%) and 1 sandpit (8.3%) at 3 households (9.1%). Of the total 550 examined soil samples, 4 (0.7%) were found to contain Trichuris and Toxocara eggs, with an average density of 1.5 and 2.0 eggs per sample. The study showed a low level of soil contamination, which was the result of inhabitants care about the sanitation of their domiciles. However, the results of the questionnaire survey demonstrated the need to warn rural residents about the risk factors for zoonotic helmints infections. In particular, parents should be advised how to minimize the threat of parasitic diseases for children in the rural environment. The presented study showed that promotional campaigns implemented in recent years on the prevention of parasitic zoonoses have had little effect to increase the awareness of the rural community. The present results confirmed that Toxocara is the most common zoonotic agent among geohelminths in the rural environment.

In this paper, the measurement of natural radioactivity in Sheep meat samples from different regions of Karbala governorate by using (Na(Tl)) detector. The results of measurements have shown that the specific activity and the determination of some other related parameters such as (Raeq , Hin, Iɣ, Iα, DƔ, Eff dos and AGDE). In fourteen four sheep meat samples by using NaI(Tl) detector. The results have shown that, the mean specific activity of (40K, 238U and 232Th) which were (6.813±1.82 Bq/kg, 3.865±1.033 Bq/kg and 1.02±1.03), respectively, were found to be less than the recommended values of specific activity given by (UNSCEAR, 2000).

Opis:
Modern agriculture foresees the implementation of a particular technological operation, according to the appropriate map-task, which is developed pre-based on diverse information. Knowledge of a certain structure of soil cover variability, obtained using information and technical systems of local operational monitoring of the agrobiological state of agricultural lands, allows us to adopt effective operational decisions for efficient management of agrobiological potential of agricultural lands. Obviously, under such conditions there is a need for fundamentally new approaches to agricultural production, which is to ensure the proper quality of technological operations. The quality of the implementation of technological operations is an integral indicator of the efficiency of production of agricultural products within the agrobiological field. The necessary quality of implementation of the basic technological processes in plant growing is provided by the integrated information and technical systems of operational monitoring of the agrobiological state of agricultural lands. This opens new prospects for organic farming using such smart agricultural machines. In connection with it the task is to obtain reliable data on the agrobiological state of the soil environment by reducing the error in determining the magnitude of the electrical conductive properties of the soil, providing individual stabilization of the working electrodes and the mechanism of lifting / lowering the working electrodes, copying inequalities of the soil environment, reducing the intensity of the destruction of the soil structure , selfcleaning of the working contact of the electrode and ensuring the stability of the electrical contact of the electrode with the soil, by instrument design perfection. The task is achieved by using the information and technical system of operational monitoring of the soil environment of the structure to determine the conductive characteristics of the soil environment. The purpose of the research is to determine the critical loading at the loss of stability by thin-walled working electrodes made in the form of working electrodes of various shapes (thin-walled solid, three-spit and four-spindle discs with different thickness of the rim). The information and technical system of localoperational monitoring of agrobiological state of soil environment of different configurations with one-side compression.

Opis:
Available techniques for dealing with uncertainties in the agro-industrial complex and their use for describing and assessing the adequacy of the decisions taken are incomplete, and often ineffective, as they usually do not take into account the combination of "field-machine-technological material", which prevents acceptance effective solutions for managing agro-biological potential of agricultural land and, as a consequence, obtaining the maximum economic efficiency of agricultural production. Reliable estimation of variables of agricultural production parameters using the "field-machine-technological material" model makes it possible to provide optimal control of available technical equipment (machinery, sowing machines, etc.), agro-biological (humus content, presence of nutrients, micro-and macro elements, etc. in soil or plant ) and technological resources for making adequate decisions and managing agro-biological potential of agricultural lands, which will provide the necessary economic efficiency. The task is achieved by ensuring the proper quality of the implementation of technological operations that are an integral indicator of economic efficiency and allow providing the necessary economic efficiency through optimal and efficient management of technical means for optimal action on the agro-biological potential of the field and the use of available technological resources. Such control is possible with the use of information and technical systems of local operational monitoring, which are located on machine-tractor units and provide effective control of technological operations by acting on the executive bodies of agricultural machines on the basis of data characterizing the agro-biological state of the soil environment. Information and technical systems of local operational monitoring of the agro-biological state of agricultural lands are used in the following cases: - before performing a technological operation, - simultaneously with the implementation of the technological operation (sowing, fertilizer application, etc.), - during the growing season and after harvesting. This opens new prospects for organic farming using such "smart" agricultural machines.

Opis:
The paper deals with the contemporary idea ofsoil parameter used in the engineering- geological analysis. The statistical basis of a characteristic and a design value of the geotechnical parameter based on Eurocode 0 is given. On this basis the idea of soil parameter describing as a spline function and its use for subsoil probabilistic analysis is presented. Furthermore, correlation between the results of tests on undisturbed and reconstructed samples, based on diagrams from Polish Standard PN-B-03020:1981, is discussed. Finally, some conclusions regarding the necessity of a more advanced and complex approach to the engineering-geological analysis are proposed.
