In micro-plot experiments growth, nodulation and seed yields of pea, yellow lupine and soybean grown in a soil colonized by high populations of pea and lupine rhizobia and low population of soybean rhizobia as influenced by seed or soil application of rhizobial inoculants were studied. The studied inoculation method had no significant effects on root nodule numbers, plant growth at the flowering stage and on seed yields of pea and yellow lupine in comparison to uninoculated control treatments. In the case of soybean seed and soil inoculation with soybean rhizobia (Bradyrhizobium japonicum) resulted in a significant increase of nodulation intensity, fresh and dry mass of shoots at the flowering stage as well as pod numbers and soybean seed yields at harvest. Soybean grown on plots in which soil was inoculated with the symbiotic bacteria gave seed yield by about 57 % higher as compared to that of soybean grown from seed inoculated with the rhizobia and by 169 % higher than when this crop was grown on the control (uninoculated) plots.

The aim of this work was to examine the effects of A. chroococcum on the prolifera-tion of R. leguminosarum bv. viciae (Rlv) in a solid-carrier inoculant and on symbiotic effectiveness of Rlv with pea plants grown under laboratory and field conditions. In a laboratory experiment it was found that proliferation of both bacterial species, Rlv and A. chroococcum, in the dual-culture inoculants was efficient, and that A. chroococ-cum had no adverse effects on the development of the rhizobia (Rlv) in the solid-carrier inoculant. In a pot experiment the highest number of nodules was detected on roots of pea plants inoculated with the dual-culture inoculant containing Rlv and A. chroococcum, slightly lower numbers on pea roots inoculated with the mono-culture inoculum of Rlv and almost no nodules were found on the roots of pea un-inoculated (control treatment) with the bacteria. In the micro-plot experiment conducted in the years 2011–2012 pre-sowing inoculation of pea seeds with the mono-culture inocu-lant of Rlv or with the mixed inoculant of Rlv and A. chroococcum slightly increased nodule numbers/plant, pod numbers/plant and seed numbers/pod, as compared to the un-inoculated control, but these differences were not reflected in pea seed yields/m2, which were similar in all treatments.

W pracy omówiony został problem przeliczania wyników profilowania gamma, wykonanego sondami starego typu w jednostkach fizycznych, w postaci zliczeń na minutę – [cpm] (counts per minute) na standardowe jednostki profilowania gamma – [API] (American Petroleum Institute). Przeliczanie jednostek profilowania gamma jest efektem zapotrzebowania na reinterpretację wyników profilowań geofizyki otworowej z otworów odwierconych przed rokiem 1990, m.in. w celu poszukiwań gazu zamkniętego w łupkach (shale gas). Do przeliczenia jednostek wybrano odcinek formacji modryńskiej z otworu A, zlokalizowanego w synklinorium lubelskim, wykorzystując metodę reperów litologicznych. Dokonano także automatyzacji tego procesu poprzez utworzenie skryptu w języku Python, w programie Techlog (Schlumberger).

The article presents the problem of gamma ray log units conversion. Gamma ray log was carried out using Soviet – type tools. The process of units conversion from counts per minute [cpm] into standard gamma ray units [API] was made. Recounting of gamma log units results from the need for the reinterpretation of old well logs (made before the 90’s), i.e. to find unconventional resources such as shale gas. A part of the Modryń formation in well A, which is located in the area of Lublin Synclinorium was chosen for units conversion. For the recounting the lithology benchmarks method was used. Automatization process was delivered by building up a PYTHON script in the Techlog program (Schlumberger).

Increase of sewage sludge production in Poland requires undertaking specific methods for their utilization and disposal. The reason is that sewage sludge, in addition to being rich in organic matter, and biogenic compounds such as nitrogen and phosphorus, which are beneficial from an agricultural point of view, also contain heavy metals, toxic organic pollutants such as persistent organic pollutants and polycyclic aromatic hydrocarbons, inorganic compounds such as silicates and clay, and pathogenic bacteria and other microbial contaminants. This implies problems with further use of such polluted sludge as fertilizer in agriculture. The aim of this paper is to analyze the possibilities and limitations of natural management of sewage sludge, taking into account their effects on the restoration and conservation of organic matter in the soil and the yielding of plants. In addition, the main methods of treatment of polluted sludge before introducing it into the environment are considered.

Main goal of article was design, develop and control of Stop&Go system in Mild Hybrid Drive using supercondensator and starter with permanent magnets. Many researches and tests were done to determine real and then representative cycles of drive in Silesian agglomeration in Gliwice and Zabrze. Road researches enabled carrying out analysis of fluidity of traffic in cities and setting a percentage shares of movement micro stages (selected accelerations, driving with constant speed, braking, stopover). Researches of usefulness of supercondensators' system as an energy source in process of starting an internal combustion engine were done. Usage of supercondensators as an energy source of starting led to improvement of economic indicators of the Stop & Go system. Supercondensator has a 1000 times bigger durability than PbPbO2 battery with around 40 times smaller mass. Researchers of real characteristics of the car Fiat Palio Weekend 1,2 8V were done for calculations of traditional characteristics The Stop & Go system was designed and produced for this vehicle A starter, which will have NeFeB magnets built in stator instead of induction winding, was designed. A modernization of the starter is necessary because of different type of working - frequent starting of the internal combustion engine. A project of the Stop & Go system was carried out in the Fiat Palio car a project of the Stop & Go system for Mild Hybrid drive and verification of correctness of working has been carried out in the Fiat Palio car.

Przedstawiono badania wpływu ochronnego szczepów Azospirillum spp. i Pseudomonas stutzeri na liczebność mikrobiologiczną w rędzinie wapiennej świeżo skażonej mieszaniną WWA i ON. Po zastosowaniu szczepienia roślin stwierdzono statystycznie istotny wzrost liczby drobnoustrojów glebowych (ogólnej liczby bakterii, promieniowców, bakterii amonifikacyjnych, proteolitycznych, celulolitycznych, rozkładających fosforany oraz kopiotrofów i oligotrofów) oraz statystycznie znaczny spadek ogólnej liczby grzybów. Stwierdzono ponadto stymulujący wpływ oleju napędowego w dawkach O,1 i 1 % na wzrost liczby wymienionych drobnoustrojów.

Rhizodegradation is the breakdown of organic contaminants in soil by soil dwelling microbes which is enhanced by the rhizospheres presence. The soil used in the experiment was collected from 0-30 cm layer in the uncontaminated area of agricultural use (Mięćmierz, Kazimierz Dolny, Poland). Pot experiment was conducted to evaluate the number of microorganisms in rendzina freshly contaminated with PAH's, diesel fuel and mixtures of PAH's and diesel fuel using inoculation of meadow feascue with rhizospheric bacteria Azospirillum spp. and Pseudomonas stutzeri. The strains of Azospirillum spp. and Pseudomonas stutzeri were able to nitrogen fix and degrade PAH's as the only source of carbon and energy. Experiment was carried out as a chamber pot study. Plants had been cultivated for 30 days and then harvested. The total number of various bacteria (ammonifiying, proteolitic, able to degrade phosphorus, copiotrophic, oligotrophic), actinomycetes and fungi in soil before and after vegetation period of investigated soil were the basis for the determination of the effectiveness of the inoculation of plants with Azospirillum spp. and Pseudomonas stutzeri. This research has confirmed higher total number of microorganisms after increase on total number of fungi in rendzina after inoculation of plants with all doses of P AH' s: total number of bacteria, actinomycetes and lower number of fungi. Statistically important decrease of total number of different bacteria and actinomycetes and statistically important increase on total number of fungi in rendzina after grown of meadow feascus inoculated with Azospirillum spp. and Pseudomonas stutzeri were observed together with increase of pollution doses. Number of different bacteria and actinomycetes were statistically higher in soils polluted with diesel fuel at the doses 0, I and 1 %. The differences in concentration between the inoculated or non-inoculated soils indicate that the presence of plant roots, in addition to the period of time, contributes to grown and adaptation of Azospirillum spp. and Pseudomonas stutzeri to a soil freshly polluted with P AH' s and diesel fuel.

W artykule opisano początkowy etap konstrukcji napędu hybrydowego samochodu osobowego o strukturze Mild Hybryd. Przedstawiono badania super-kondensatora w procesie rozruchu silnika spalinowego, wyznaczono energię zużytą do rozruchu silnika oraz czas trwania rozruchu. W pracy badano rozrusznik Magnetti Marelli-Denso E80E 12 V 1,0 kW w samochodzie marki Fiat Palio Weekend. Rozrusznik był zasilany z akumulatora kwasowo-ołowiowego, a następnie z superkondensatora. System Stop & Go w samochodzie pozwala na automatyczne wyłączanie silnika spalinowego podczas postoju (np. w korku lub na czerwonym świetle), a następnie szybkie załączenie. Takie działanie pozwala w miastach na obniżenie zużycia paliwa oraz emisji dwutlenku węgla. Tematyka pracy jest zgodna z wymogami ograniczania emisji CO2 przez państwa Unii Europejskiej. Szczególną uwagę przykłada się do działań w sektorze transportu samochodowego (protokół z Kioto oparty na UNFCCC, Europejski Program ds. Zmian Klimatycznych i wynikające z niego programy Inteligentna Energia dla Europy [1, 2, 3, 4, 5, 6, 7, 8]).

The Automobile Stop & Go System makes it possible to switch off an IC engine automatically when the vehicle stops (e.g. at red light or in traffic jams) and then to switch it on quickly again. This makes it possible to reduce the fuel consumption and carbon dioxide emission. The paper describes the initial stages of design of the Mild Hybrid drive system of a hybrid electric car. The results of the supercapacitor performance during IC engine start-ups are presented. The energy consumption at start-up together with the start-up time were calculated. The Magnetti Marelli-Denso E80E car starter of rating: 12 V, 1.0 kW, used in Fiat Palio Weekend, was employed in the tests. The starter was supplied from a lead-acid battery at first, then the supercapacitor was applied. The Stop& Go systems are at present undergoing rapid development, since the European Union regulations introduce further decrease in the carbon dioxide emission standards in agreement with the Kyoto protocol based on UNFCCC, the European Climate Change Programme and the Intelligent Energy Europe programs.
