Histological and Ultrasonographic Monitoring of Folliculogenesis in Puerperal Ewes after Spring Lambing

Vlckova R. , I. Valocký, G. Lazar, D. Sopkova, I. Maracek: Histological and Ultrasonographic Monitoring of Folliculogenesis in Puerperal Ewes after Spring Lambing. Acta Vet. Brno 2008, 77: 65-72. The time of the first ovulation depends on the sheep breed, feeding conditions, year season, length of lamb nursing and following galactopoiesis. The objective of the present study was to analyse the follicle status after parturition in non-lactating Improved Valachian ewes. Laparotomy with following ovariectomy was performed after lamb weaning (spring) on days 17, 24 and 32 after parturition. The ovaries were USG analysed with 5.0 MHz linear and 7.5 MHz convex transducer. Follicular data were analysed quantitatively and qualitatively. The ovaries were collected at the end of laparotomy and fixed in 10% formalin. The sections of the ovarian tissue were stained with haematoxylin and eosin and Azan staining. Ovarian slides were microscopically studied and analysed by LUCIA-G ver. 4.71. The differences in the ovary size were not significant. The number of follicles 3 mm (P < 0.001). The rate of atresia was 82% and 89% on day 17 and on day 32 post partum, respectively. We observed single ovulation on day 17 and double ovulations on days 24 and 32 post partum. More than half of the total number of antral follicles visible on the ovary surface was prepared for recruitment and this number was higher on day 32 post partum. Follicle selection connected with a relatively low rate of atresia and responsible preovulatory follicle sizes opened the way for selecting more follicles for the dominance process and thus also for the occurrence of double ovulations.

CULTURAL IDENTITY, COLLECTIVE SELF-IMAGE AND RELIGIOUS CONSCIOUSNESS IN ECUADOR

The study of the Ecuadorian cultural identity, presented in this paper, is based on interviews of 1000 people in the coastal area of Ecuador. The results of the interviews show that the Ecuadorian people ground their national pride predominantly on the uniqueness of the Ecuadorian nature. Thus, the paper discusses the main constituents of the Ecuadorian cultural identity, which contribute to its specificity and uniqueness and which differentiate it from the other Latin American identities. Also, the research is focused on the level of ethnocentric consumerism in Ecuador and on its relation to the Ecuadorian national identity. An important finding of this paper is that the Ecuadorian people are rather religious and that religiousness has a special importance in both the Ecuadorian private lives and in the public sphere. This is why also the paper claims that religious feelings form the core of the Ecuadorian cultural identity, although not all the individuals might be aware of this fact. Finally, the paper discusses the relationship between national and civilizational identities in the Ecuadorian case, or between the 'Ecuadorianness' and the 'Latin Americanness" of the Ecuadorian people. In most of the cases the two identities are seen as a pair, where each one of the two compliments the other, rather than suppressing or competing with it. Thus, on the basis of the interviews a model of the Ecuadorian cultural identity is outlined.
Suppression of semantic features in metaphor comprehension

Abstract Looking at Glucksberg’s class-inclusion model of metaphor comprehension, this article suggests that metaphorical classes are created by a suppression-oriented mode of comprehension. To give a picture of this mechanism, it draws on a model according to which every metaphorical class is formed by the inhibition of the majority of semantic features and maintaining a very small set of those features. The product of this suppression-oriented mode of comprehension is a broad class which might include a lot of entities. All these entities create a metaphorical class which is defined by one, or at most, a few aspects of meaning. The suppressed aspects of meaning do not have any role in the creation of metaphorical classes. In other words, broad metaphorical classes are produced by a suppression- or inhibition-based mechanism through which the majority of semantic aspects are completely filtered out. Those semantic features which have a high degree of co-occurrence with other semantic features are not good criteria for defining metaphorical classes.
Prerequisites of Employee Empowerment: The Case of Jordanian Mobile Phone Companies

Data from 191 service employees in Jordanian mobile companies have shown a positive and significant association among four empowerment prerequisites or antecedents (including trust, incentives, communication and flow of information, and knowledge and skill) and empowerment of mobile companies' sales representatives. The results in this study suggest that the independent variables, trust, incentives, communication and flow of information, and knowledge and skill have a direct and strong impact on the dependent variable; employee empowerment. As such, the empowerment prerequisites in this study accounted for the significant variation in the level of empowerment among service employees in the mobile industry. Implications for future research and for managerial practices are also discussed.
Characterization and Identification of Lactic Acid Bacteria in þÿ

29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 A total of 176 lactic acid bacteria (LAB) isolated from a typical Spanish blood sausage called “morcilla de Burgos” were identified by means of phenotypic characteristics and 16S rDNA RFLP (ribotyping). LAB were isolated from “morcilla” of different producers and in different storage periods, that includes unpackaged, vacuum and modified atmosphere packaged “morcilla” and vacuum packed and pasteurised “morcilla”. The knowledge of specific spoilage bacteria of ”morcilla de Burgos” will be useful to design new preservation methods to extent the shelf-life of this product. Identification made according to phenotypic and biochemical characteristics shows the majority of the isolates were heterofermentative LAB (93.2%) and eight different bacterial groups could be distinguished (A-G). W. viridescens was the main species detected (42%). In addition, Leuconostoc spp. (23.9%), W. confusa (11.4%) and Lactobacillus fructosus (5.7%) species were found. Few strains were phenotypically missidentified as Lb. sanfrancisco, Pediococcus spp. , Lb. sakei/curvatus and Carnobacterium spp. and 11 strains remained unknown. Most of the leuconostocs were identified as Lc. mesenteroides and Lc. carnosum species. Ribotyping shows a quite good correlation with phenotypic methods, although it has been possible to identify 15 different clusters. W. viridescens and leuconostocs were also the predominant LAB. Strains identified as W. confusa by phenotypic characteristics were resolved in W. confusa and W. cibaria by ribotyping. Neither Carnobacterium piscicola nor Lb. sanfrancisco were identified by means of genotypic method. All Lb. fructosus strains and some more included in different phenotypic groups (17 strains in total) could not be associated with any reference strain (cluster VII). Although some discrepancies exists the combination of phenotypic and genotypic methods led to a better identification and characterization of the strains isolated from “morcilla de Burgos”.
Interplay of chromatin remodeling and stress gene repression

Eukaryotische Zellen aktivieren sogenannte Stressgene und reagieren damit auf plotzliche Veranderungen in ihrer Umwelt, wie z.B. einer Erhohung der Temperatur oder Osmolaritat. Die Expression dieser Gene ist ein stark regulierter Prozess der unter anderem vom Verpackungsgrad der DNA abhangig ist. DNA liegt im Zellkern in der komprimierten Form des Chromatins vor, dessen kleinste Grundeinheit das sogenannte Nukleosom darstellt. Nukleosomen bestehen aus 8 Untereinheiten von Histon- Proteinen, um die 147bp der DNA gewickelt sind. Das Ausmas der Komprimierung von bestimmten DNA Abschnitten bestimmt deren Zuganglichkeit fur die transkriptionelle Maschinerie und somit ob bestimmte Gene exprimiert werden. Es gibt verschiedene Proteine und Proteinkomplexe innerhalb des Zellkerns, die Chromatinstrukturen verandern konnen. In dieser Arbeit beschaftige ich mich mit dem aus insgesamt 15 Untereinheiten aufgebauten, ATP abhangigen Chromatin Remodeling Complex INO80. Der einfache Eukaryont S.cerevisiae dient als Modellsystem um den Einfluss dieses Proteinkomplexes auf die transkriptionelle Regulation von Stressgenen zu untersuchen. Ein Modul aus Actin, Arp4 und Arp8, sowie Arp5 und die Ino80 ATPase sind jene Hauptakteure des INO80 Komplexes, die einen inhibierenden Effekt auf die Transkription von Stressgenen ausuben. In Mutanten welchen eine dieser Untereinheiten fehlt, wird eine verstarkte, langer andauernde Transkription von Stressgenen beobachtet. Dieser Effekt scheint ein allgemeiner Mechanismus zur Regulierung sehr stark exprimierter Gene zu sein. Der inhibierende Effekt des INO80 Komplex beruht sehr wahrscheinlich auf der Wiederherstellung jener Nukleosomen, die durch transkriptionelle Aktivierung vom Promoter entfernt werden. Die Wiederherstellung der Promoternukleosomen ist in Mutanten, welchen entweder Arp8 oder Ino80 fehlt, zeitlich stark verzogert. Mithilfe einer ATPase- inaktiven Mutante der Ino80 Untereinheit wird gezeigt, dass ATP Hydrolyse fur die transkriptionell inhibierende Wirkung des INO80 Komplex notwendig ist. Auserdem wurde versucht Untereinheiten zu identifizieren, die fur die Rekrutierung des Komplexes zu Stressgenen notwendig sind. Nach den vorliegenden Ergebnissen werden Arp4, Arp5 und Arp8 nicht fur diese Aufgabe benotigt und sind somit hauptsachlich fur die Aktivitat des INO80 Komplexes zustandig.
Stability in stochastic language change models

Exemplar models are a popular class of models used to describe language change. Exemplars are detailed memories of stimuli people are exposed to, and when modelling language change are represented as vectors where each component is a phonetic variable. Each exemplar is given a category label, representing what that sound is identified as. New sounds are categorized based on how close they are to the exemplars in each category. Newly categorized exemplars become a part of the system and affect how the future sounds are produced and perceived. It is possible in certain situations in language for a category of sound to become extinct, such as a pronunciation of a word. One of the successes of exemplar models has been to model extinction of sound categories. The focus of this dissertation will be to determine whether categories become extinct in certain exemplar models and why. The first model we look at is an exemplar model which is an altered version of a k-means clustering algorithm by MacQueen. It models how the category regions in phonetic space vary over time among a population of language users. For this particular model, we show that the categories of sound will not become extinct: all categories will be maintained in the system for all time. Furthermore, we show that the boundaries between category regions fluctuate and we quantitatively study the fluctuations in a simple instance of the model. The second model we study is a simple exemplar model which can be used to model direct competition between categories of sound. Our aim in investigating this model is to determine how limiting the memory capacity of an individual in exemplar models affects whether categories become extinct. We will prove for this model that all the sound categories but one will always become extinct, whether memory storage is limited or not. Lastly, we create a new model that implements a bias which helps align all the categories in the phonetic space, using the framework of an earlier exemplar model. We make an argument that this exemplar model does not have category extinction.
When Law Students Read Cases: Exploring Relations Between Professional Legal Reasoning Roles and Problem Detection

This study investigates effects of different legal reasoning roles on first-year law students' case reading and analysis, focusing detection of textual and legal interpretation problems arising within and between related appeal court cases. In a between-subject design, 56 first-year law students received 1 academic and 3 professional role scenarios, each involving a different communicative frame. Scenarios contained instructions to think aloud, while students read the same 3 related appeal court cases. Protocols were scored using a list of interpretative problems developed from pre-experimental task analysis. Results show that detection varies with the communicative frame embedded in different professional roles. On overall problem detection, students in the advocatory and policy scenarios performed significantly better than students in the (academic) class recitation scenario. Advocatory and advisory groups also performed significantly better than students in the class recitation group in detecting critical interpretative problems. Results further showed that students who switched between cases while reading (as opposed to reading linearly) scored significantly better on all problem detection measures. Unlike previous studies of legal case reading, this study contributes to understanding by focusing on interpretative problems located in and between related cases, rather than focusing on readers' accurate recovery of meaning per se.
RELATIONSHIP BETWEEN DIRECT PARTICIPATION SCHEMES AND ORGANIZATIONAL PERFORMANCE IN GOVERNMENT OWNED AGENCIES IN KENYA

The purpose of the study was to explore the degree to which direct employee participation practices in the organization contribute to organizational performance. Direct participation schemes in the organization include empowerment of individuals through attitude surveys, suggestion schemes and use of various work teams. In the study, these components formed the independent variables, while organizational performance was the dependent variable. The study was a descriptive survey design and utilized a correlation studies strategy to establish the relationship between independent and dependent variables. Multi stage sampling procedure was used for this selection, which identified a sample of 378 respondents who were expected to participate. The sampling frame was from a list of 178 state corporations that participated in performance contract in 2010/2011, with a population of 86, 878 workers. Questionnaire was the main data collection instrument. A pilot study was carried out in two organizations. In the main study data was collected from a sample of 400 respondents categorized as managerial, supervisory and ordinary workers in state corporations. Usable and valid questionnaires from 348 respondents in 20 select state corporations in Kenya were returned and used for the study. Descriptive and inferential statistics were utilized. Correlation was analyzed using Pearson’s correlation method and with the help of SPSS tool to determine relationships between variables. Hypotheses were tested to establish whether various participation schemes had significant influence on the performance of state corporations in Kenya. Findings indicated a strong relationship between direct participation and performance of state corporations in Kenya. Direct team based participation was the more preferred mode of participation, compared with direct individual-based participation. One limitation of the findings is the use of self-report questionnaires to collect data on all measures. The study recommends enhancement of empowerment programmes as a business strategy aimed at improving performance, and stakeholder attitude; especially management and labor work attitudes. Future studies could investigate the level of planned performance management systems as a business and competitive strategy in the public sector.
Agricultural Commodity Price Volatility and Its Macroeconomic Determinants: A GARCH-MIDAS Approach

This paper investigates the main drivers of the agricultural commodity price volatility using the GARCH-MIDAS model of Engel et al. (2013), a new class of component models that allows for isolating the low-frequency component of volatility and taking into consideration macroeconomic factors via mixed data sampling. We show that modelling the agricultural price volatility as the product of high and low frequency components is more efficient than filtering it through a standard GARCH(1,1) model. After combing wheat, corn and soybean daily prices with monthly market-specific and common macroeconomic drivers over the period 1986-2012, it appears that supply-demand indicators and conventional speculation proxies are crucial in explaining the low-frequency component of volatility while monetary factors and energy markets play significant but less important role. Nevertheless, when we consider only the period following the recent price spikes (2006-2012), the monetary factors –especially interest rate – become essential to describe agricultural price fluctuations, suggesting also that the heterogeneity in the effects of the drivers on different crops is decreasing.
Parameterizing total storm conduction currents derived in a global model [poster]

Electrified clouds are thought to play a major role in the global electric circuit. These clouds produce currents from the top of thunderstorms which help maintain the potential difference between earth's surface and the upper atmosphere. Previously, currents for different types of electrified clouds were estimated from overflights of the NASA ER-2 aircraft and compared with radar derived dynamical and microphysical properties (Deierling et al., this conference). In this study, high resolution model output from the Community Earth System Model (CESM) is compared with reanalysis data to determine the skill of CESM at representing these microphysical and dynamical properties of storms. Then, these storm properties are used to infer global distributions of conduction currents over different temporal scales and compared with data derived from the lightning imaging sensor (LIS) and precipitation radar (PR) measurements onboard the Tropical Rainfall Measuring Mission (TRMM) satellite.
Optimisation of inoculation of Leucaena leucocephala and Acacia mangium with rhizobium under greenhouse conditions

Nos travaux ont porte sur l'optimisation de l'inoculation de 2 especes agroforestieres de legumineuses ligneuses: Leucaena leucocephala et Acacia mangium avec differentes souches de rhizobium. Tout d'abord, nous avons montre que le stade physiologique de la culture bacterienne n'a aucune influence sur la nodulation et la croissance des plants d'Acacia mangium inocules et cultives in vitro pendant 4 mois. Pour Leucaena leucocephala, le nombre de nodules est significativement superieur pour les plants inocules avec une culture bacterienne en phase plateau. En revanche, quelle que soit l'espece, aucune difference significative n'est notee en ce qui concerne le poids sec des parties aeriennes. L'effet de la taille de l'inoculum sur la nodulation et la croissance des plants de L. leucocephala a ete etudie apres 5 mois de culture en serre. Nos resultats ont montre qu'une inoculation avec des cutures bacteriennes contenant 1010 a 109 bacteries par millilitre sont les conditions optimales pour avoir une nodulation et une croissance maximale des plants. Les 2 especes de legumineuses montrent des differences significatives en ce qui concerne l'effet de la methode d'inoculation sur la nodulation et la croissance des plants. Pour Acacia mangium, l'inoculation avec une culture liquide une semaine apres les semis est plus favorable pour la croissance de la plante. En revanche, pour Leucaena leucocephala, cette methode classique d'inoculation de meme que l'enrobage des semis avec une culture bacterienne melangee avec de la gomme arabique ameliorent significativement la croissance de la plante. Nos travaux pourront servir aux partenaires du developpement pour la production en regie de plants forestiers de ces 2 especes. (Resume d'auteur)

Properties of a bifurcated current sheet observed on 29 August 2001

Abstract. Ion density, velocity and temperature, measured by Cluster spacecraft in the plasma sheet during an isolated substorm at 10:20-11:15 UT, 29 August 2001 are discussed. The Custer/CODIF data for subinterval 10:55-11:03 UT, during which a bifurcation of the current sheet was detected, are studied in particular. It is shown that ion density and temperature have a plateau-like profile in the central part of the bifurcated current sheet. An enhanced proton flow directed in positive Y GSM was detected during the selected subinterval. Other components of proton bulk velocity are found to be negligibly small, i.e. the structure is likely not directly associated with magnetic reconnection. Alternative models, including ion anisotropy and localized magnetic turbulence, which result in a two-peak profile of the current density, are discussed briefly.
The infrared dust bubble N22: an expanding Hii region and the star formation around it

Aims. To increase the observational samples of star formation around expanding Hii regions, we analyzed the interstellar medium and star formation around N22. Methods. We used data extracted from the seven large-scale surveys from infrared to radio wavelengths. In addition we used the JCMT ? observations of the J = 3-2 line of 12 CO emission data released on CADC ? and the 12 CO J = 2-1 and J =3-2 lines observed by the KOSMA ? 3 m telescope. We performed a multiwavelength study of bubble N22. Results. A molecular shell composed of several clumps agrees very well with the border of N22, suggesting that its expansion is collecting the surrounding material. The high integrated 12 CO line intensity ratio RICO(3 2)=ICO(2 1) (ranging from 0.7 to 1.14) implies that shocks have driven into the molecular clouds. We identify eleven possible O-type stars inside the Hii region, five of which are located in projection inside the cavity of the 20 cm radio continuum emission and are probably the exciting-star candidates of N22. Twenty-nine YSOs (young stellar objects) are distributed close to the dense cores of N22. We conclude that star formation is indeed active around N22; the formation of most of YSOs may have been triggered by the expanding of the Hii region. After comparing the dynamical age of N22 and the fragmentation time of the molecular shell, we suggest that radiation-driven compression of pre-existing dense clumps may be ongoing.
The Paleogene of the Podhale Basin (Polish Inner Carpathians) - micropaleontological perspective

Recent investigations of the calcareous nannoplankton, small foraminifera and dinoflagelIata has thrown additional light on the age and environment of deposition of the Paleogene deposits of the Podhale Basin. Large and small foraminifera indicate for the Nummulite Eocene Bartonian-early Priabonian age and accumulation in different ernvironments of the shallow carbonate platform. Planktic foraminifera from the uppermost slope grey marls indicate P 15-P 16 zone while calcareous nannoplankton data are inconsistent indicating NP 16-NP 17 or 19/20 coccolith zones. The turbidite deposits of the Podhale flysch accumulated predominately during the Oligocene.
