Opis:
The aims of this study was to see the effect of breed, parity and scheme of collection on the quality and quantity of OPU derived oocytes and effect of transvaginal ultrasound guided follicular aspiration on subsequent fertility of donor cows. A total of 28 animals (11 Boran and 11 Boran Holstein-Friesian cross for once per week collection, and 7 Boran and 7 Boran Holstein-Friesian cross for twice per week collection) were used in this experiment. A total of 22 animals were evaluated for the effect of the OPU procedure on subsequent reproductive function. In 150 Ovum Pick up sessions, irrespective of collection scheme, breed and parity, 1124 follicle (554 in Boran and 570 in HF crosses) were punctured with a recovery rate of 51.1% in Boran and 48.6% in the crosses. Relatively more follicles were aspirated in crosses compared to Borans although the difference in oocyte recovery rate and quality were not statistically significant. Overall recovery rate was 57.7% in heifers and 42% in cows. Frequency of aspiration significantly influenced (P<0.05) oocyte recovery rate with more follicles aspirated in Once per week per session compared to twice per week per session but there was no difference in the mean number of recovered oocytes. A significantly higher number of follicles were aspirated (P<0.05) and good quality oocytes were greater in heifers than cows. Different COCs quality grades were recovered from breed, parity and frequency of collection category. Overall from a total of 574 collected COCs, about 326 (57%) of the recovered COCs were of the quality grades I and II, whereas 248 (43%) were with quality grades III and IV. All 22 animals showed estrus on average after 19 days of the last OPU procedure though a relatively weaker intensity of estrus signs, irregularity of the cycle and minor ovarian morphological change were noted. Response rate to a single PGF2α treatment on 18 animals was 72% (13/18). Subsequent insemination of those in estrus resulted in 53.8% (7/13) first service conception rate. In conclusion, parity, and to some extent frequency of collection had a significant effect on the quality and quantity of oocyte but not breed. Animals at post OPU were able to continue cycling and become pregnant.

Opis:
The objective of the study was to determine whether the presence of CL on the ovary can influence the number and quality of COCs recovered using needle aspiration technique. A total 40 numbers of Bovine ovaries were collected from the local abattoirs soon after the animals were slaughtered. The specimens were classified as corpus luteum present (CL+) and corpus luteum absent (CL) groups. A total of 583 follicles were aspirated from 40 ovaries and among them 381 (62.5%) COCs were collected from CL group ovaries and 202 (37.5%) COCs from CL+ group ovaries. The COCs were also classified as Grade I (>3 layers of cumulus), Grade II (2 or 3 layers of cumulus), Grade III (no cumulus) and Grade IV (degenerated cells). Grade I and Grade II were classified as normal, and Grade III and Grade IV were considered as abnormal COCs. The result indicated that greater numbers of follicles were aspirated and COCs were collected from CL ovaries (15.24±5.27 and 9.40±3.50, respectively) than ovary with CL+. Ovaries CL contribute higher normal COCs (Grades I and II) than that of ovaries with CL+. The result of this study is a preliminary work directing suitable source of COCs for initiating and optimizing in vitro embryo production experiment in like Ethiopia having huge cattle population and animal slaughtering is more common for various reasons like to export or for domestic consumption.

Opis:
As a result of the destructions in the period 1939-1945, as well as dismantlements, modifications and reconstructions in the following years, little of the Warsaw tenement buildings from early 20th century has survived until the present. Moreover, the tenements which have survived have been subject to significant modifications. Another serious difficulty in the research and examination of Warsaw architecture from the turn of the 19th and 20th centuries are the limitations in the scope of both quality and availability of original design files, as well as illustrative materials from the period before 1939. In this context, the files from the Capital City Reconstruction Office are the only source of information on certain non-existing tenement houses. An important role in creating Warsaw tenement architecture at the beginning of the 20th century was played primarily by young architects, graduates of foreign technical schools of higher education, prepared excellently for changes in the profession as well as in the investment process. The most renowned architects from the point of view of the number and sizes of erected tenement houses, the quality of their architecture, as well as the number of modern construction and technical solutions employed were Henryk Stifelman (working together with Stanisław Weiss), as well as Wacław Heppen (working together with Józef Napoleon Czerwiński). In spite of employing modern technical solutions, some of the tenement houses erected by the two partnerships were destroyed in the years 1939-1945 and other were modified significantly in the following years. In many cases, the architecture and technical solutions of either non-existing or substantially modified tenement houses designed by the partnerships of Stifelman-Weiss and Heppen-Czerwiński had not been properly documented before 1939. An important and, in many cases, the only source of knowledge about non-existing tenement houses are documents collected in the Archives of the Capital City Reconstruction Office, as well as in the Archives Department of the Administrative Bureau of the Municipal Office of the Capital City of Warsaw. The documents collected in the files of the Capital City Reconstruction Office consist of the general part, containing maps, diagrams and basic information on the state of preservation of individual buildings, as well as the detailed one, in many cases containing the measurements of the preserved structure, correspondence, letters, photographs, cost estimates, orders and other, more detailed information. In many cases, the detailed part makes it possible to learn about the architecture of the tenement houses, their supporting structure, certain systems used in the interior, sizes and shapes of individual building elements, like, among others, cornices, bays, balconies, walls or openings, as well as determining formal reasons for dismantling or modification. In consideration of the total destruction of the original design documentation, lack of detailed examination of the buildings from the early 20th century before 1939, as well as a limited number and scope of the available illustrative material, the documentation forming the archives of the Capital City Reconstruction Office is, in many cases, considered to be a fundamental or the most important source of information about the unpreserved Warsaw tenement houses, including the tenement houses designed by the architectural and building partnerships of Henryk Stifelman with Stanisław Weiss and of Wacław Heppen with Józef Napoleon Czerwiński.

Opis:
An assessment was made of the usefulness for forcing of five cultivars of Hyacinthus orientalis L.: ‘Carnegie’, ‘City of Haarlem’, ‘Delft Blue’, ‘Jan Bos’, and ‘Lady Derby’. The bulbs were planted on 14 October 2003 and 2004 in Flexy-tray type of pallets filled with water and in plastic boxes with a standard medium. The bulbs were cooled for 12 or 14 weeks. It was found that forcing lasted shorter in the water-filled trays, while longer inflorescence stems were obtained in plants forced in the standard medium. The cooling of the bulbs for 14 weeks resulted in the shortening of the forcing time and in the lengthening of inflorescence stems.
Oceniono przydatność do pędzenia pięciu odmian hiacynta wschodniego Hyacinthus orientalis L.: ‘Carnegie’, ‘City of Haarlem’, ‘Delft Blue’, ‘Jan Bos’ and ‘Lady Derby’. Cebule sadzono 14 października 2003 i 2004 r. do palet Flexy-tray wypełnionych wodą i plastikowych skrzynek z podłożem standardowym. Cebule chłodzono przez 12 lub 14 tygodni. Stwierdzono, że pędzenie trwało krócej w paletach wypełnionych wodą, dłuższe pędy kwiatostanowe uzyskano u roślin pędzonych w podłożu standardowym. Chłodzenie cebul przez 14 tygodni wpłynęło na skrócenie pędzenia i wydłużenie pędów kwiatostanowych.

Opis:
W 1719 roku Jean-Baptiste Dubos opublikował olbrzymią rozprawę o sztuce Réflexions critiques sur la poésie et sur la peinture, w której zaproponował nowy rodzaj refleksji o tym, co artystyczne. Choć czerpał z teorii starożytników, to na szeroką skalę wprowadził do swojego dzieła nowoczesną, zwiastującą sensualizm perspektywę osobistego odbioru i indywidualnego zachwytu. Polskim teatrologom Dubos znany jest niemal wyłącznie dzięki artykułowi Zbigniewa Raszewskiego Partytura teatralna, przez co sprowadza się jego idee głównie do rozważań o możliwości stworzenia zapisu gry scenicznej. Tymczasem osiemnastowieczny teoretyk fascynował się istnieniem takiej partytury o tyle, o ile widział w niej narzędzie do wskazania aktorowi kierunku poszukiwań, której celem nie była utopijna wierność autorskiemu zamierzeniu, ale szansa na analizę wolności własnej i poszukiwania prawdy sztuki. Artykuł omawia główne strategie narracyjne zastosowane przez Jean-Baptiste’a Dubosa w traktacie, prezentuje główny obszar teatralnych zainteresowań autora i  jego wyobrażenie o zastosowaniu maski w teatrze antycznym i w komedii dell’arte. Szkicuje związki koncepcji księdza Dubosa z osiemnastowieczną teorią i praktyką paryskiego teatru.
In 1719, Jean-Baptiste Dubos published an extensive dissertation titled Réflexions critiques sur la poésie et sur la peinture, in which he proposed a new kind of reflection on art. Although he drew on ancient theories, he chiefly introduced a modern perspective of personal perception and individual enchantment to his work, foreshowing sensualism. In Polish theatre studies, l’Abbé Dubos is known almost exclusively through Zbigniew Raszewski’s article Partytura teatralna [Theatre Score]; consequently, his ideas are reduced mainly to deliberations on the possibility of creating a record of stage performance. In fact, however, the eighteenth-century theorist was fascinated by the idea of such a score inasmuch as he saw it as a tool for showing the actor the direction of exploring the part, not in order to achieve a utopian faithfulness of the author’s intention, but rather to analyse the actor’s own personal freedom and search for the truth of the play. The article discusses the main narrative strategies employed by Jean-Baptiste Dubos in the treatise and presents the main area of his theatrical interests and his idea of the function of the mask in ancient theatre and in commedia dell’arte. It also outlines the relationship between Dubos’s concepts and 18th-century theory and practice of Parisian theatre.

L’articolo presenta un’approfondita revisione del libro di James M. Bos Reconsidering the Date and the Provenance of the Book of Hosea. The Case for the Persian-Period Yehud, sullo sfondo del problema del neostoricismo negli studi biblici. Dopo aver tracciato una breve panoramica sul fenomeno del neostoricismo in generale (la sua genesi e il suo successivo sviluppo nel corso degli anni), viene discusso l’approccio di Bos in base al confronto con tali premesse ideologico-filosofiche. A tal proposito viene presentata in modo dettagliato l’intera struttura del libro di Bos, assieme alla valutazione critica dell’argomentazione da lui addotta. L’autore dell’articolo ritiene che l’approccio neostoricista alla Bibbia sia del tutto soggettivo e sbagliato, in quanto assolutizza un principio filosofico e non lascia spazio per caso, dubbio o fede. 
The article presents an extended review of James M. Bos’s book Reconsidering the Date and the Provenance of the Book of Hosea. The Case for the Persian-Period Yehud, against the backdrop of the issue of the new historicism in biblical studies. After a brief overview of the phenomenon of this new historicism (its genesis and historical development), Bos’s approach is discussed from the point of view of its ideological-philosophical context. Then a detailed analysis of the entire structure of Bos’s book is presented, along with a critical assessment of his reasoning. The author of the article argues that the new historicist approach is completely subjective and wrong, as it absolutizes a philosophical principle without admitting the element of faith or any possibility of coincidence or doubt.
