WYNIKI UŻYTKOWANIA ROZPŁODOWEGO KONIKA POLSKIEGO Z WYBRANEJ Z STADNINY KONI W POLSCE

The analysis of Polish Primitive Horse reproduction, in the stable breeding in Dobrzyniewo, was carried out in the period 1993/1994 – 2003/2004. On the basis of the carried out analysis it is evident systematic increase (positive trend) of basic coefficients of reproduction (foaling, fertility, fecundity, birth) and a decrease of coefficients of infertility and abortions. On the other hand leading sires were stallions: Mikrus and Jehol, which were utilised in reproduction for the period of 11 years while mares covered by these stallions had relatively high coefficients of reproduction.Analizę rozrodu konika polskiego z hodowli stajennej w Dobrzyniewie przeprowadzono za okres 1993/1994 – 2003/2004. Z przeprowadzonej analizy wynika systematyczny wzrost (trend dodatni) podstawowych wskaźników rozrodu (źrebności, płodności, plenności i wyźrebień), a spadek wskaźnika jałowienia i poronień. Z kolei czołowymi reproduktorami okazały się ogiery: Mikrus i Jehol, które były użytkowane rozpłodowo przez okres 11 lat, natomiast klacze kryte tymi ogierami charakteryzowały się stosunkowo wysokimi wskaźnikami rozrodu

Pd decorated Co-Ni nanowires as a highly efficient catalyst for direct ethanol fuel cells

The storage and conversion of energy necessitates the use of appropriate electrochemical systems and chemical reaction catalysts. This work presents newly developed catalysts for electrooxidation of ethanol in an alkaline medium. Nanocatalysts composed of Co–Ni nanowires (Co–Ni NWs) decorated with Pd nanoparticles (Pd NPs) were made at varying metal ratios and their chemical composition and structure was investigated in detail. The synthesis involved a wet chemical reduction assisted by a magnetic field, which led to the generation of NWs, followed by the deposition of spherical Pd NPs on their surface. The best catalytic activity was obtained for the catalyst made of Co3–Ni7 decorated with Pd NPs, which exhibited EOR of 8003 mA/mgPd for only 0.86 wt% of Pd loading. The results can be explained by the synergistic effect between the morphology of the bimetallic support and the favorable interaction of oxophilic Co, Ni with catalytic Pd

Comprehensive automation and monitoring of MV grids as the key element of improvement of energy supply reliability and continuity

The paper presents the issue of comprehensive automation and monitoring of medium voltage (MV) grids as a key element of the Smart Grid concept. The existing condition of MV grid control and monitoring is discussed, and the concept of a solution which will provide the possibility of remote automatic grid reconfiguration and ensure full grid observability from the dispatching system level is introduced. Automation of MV grid switching is discussed in detail to isolate a faulty line section and supply electricity at the time of the failure to the largest possible number of recipients. An example of such automation controls’ operation is also presented. The paper’s second part presents the key role of the quick fault location function and the possibility of the MV grid’s remote reconfiguration for improving power supply reliability (SAIDI and SAIFI indices). It is also shown how an increase in the number of points fitted with faulted circuit indicators with the option of remote control of switches from the dispatch system in MV grids may affect reduction of SAIDI and SAIFI indices across ENERGA-OPERATOR SA divisions
