Measurement of the ratio of branching fractions B(B0→K∗0γ )/B(B0s→φγ ) and the directCP asymmetry inB 0→K∗0γ
No full textThe ratio of branching fractions of the radiative B decays B0→K⁎0γ and B0s→ϕγ has been measured using an integrated luminosity of 1.0 fb−1 of pp collision data collected by the LHCb experiment at a centre-of-mass energy of s√=7TeV. The value obtained is
B(B0→K⁎0γ)B(B0s→ϕγ)=1.23±0.06(stat.)±0.04(syst.)±0.10(fs/fd),
where the first uncertainty is statistical, the second is the experimental systematic uncertainty and the third is associated with the ratio of fragmentation fractions fs/fd. Using the world average value for B(B0→K⁎0γ), the branching fraction B(B0s→ϕγ) is measured to be (3.5±0.4)×10−5.
The direct CP asymmetry in B0→K⁎0γ decays has also been measured with the same data and found to be
ACP(B0→K⁎0γ)=(0.8±1.7(stat.)±0.9(syst.))%.
Both measurements are the most precise to date and are in agreement with the previous experimental results and theoretical expectations
First observation of the decay Bs0→K*0K*0
No full textThe first observation of the decay B0s→K∗0K∗0 is reported using 35 pb−1 of data collected by LHCb in proton–proton collisions at a centre-of-mass energy of 7 TeV. A total of 49.8±7.5 B0s→(K+π−)(K−π+) events are observed within ±50 MeV/c2 of the B0s mass and 746 MeV/c2 < mKπ < 1046 MeV/c2, mostly coming from a resonant B0s→K∗0K∗0 signal. The branching fraction and the CP-averaged K∗0 longitudinal polarization fraction are measured to be B(B0s→K∗0K∗0)=(2.81±0.46(stat.)±0.45(syst.)±0.34(fs/ fd))×10−5 and fL =0.31±0.12(stat.)±0.04(syst.)
Tyranny on Trial: Personality and Courtroom Conduct of Defendants Slobodan Milosevic and Saddam Hussein
No full textIn this essay in the Symposium on Milosevic & Hussein on Trial, the author explores the impacts of personality & courtroom conduct in trial outcome to argue that the likenesses between the two defendants will result in Saddam\u27s projection of grand defiance. Biographical narratives of the two leaders trace the psychological development of each personality through childhood to their political careers characterized by defiant resistance & compensatory grandiosity that may be the source of the similarities of behaviors in the courtroom. Asserting that Saddam is following the Milosevic model of courtroom behavior by derailment of the proceeding, exploitation of the victimization theme, & distortion of history to present his political platform, the author concludes that, defiant & unrepentant, both defendants have returned to the international stage to restate their heroic legacies.

Using Building Information Modeling (BIM) and the Last Planner System (LPS) to Reduce Construction Process Delay
No full textThe construction industry suffers from many practical problems and challenges; most being related to construction management. One of the most common recurring problems in construction projects is delay. Delay is a primary factor that can have an effect on project duration, scheduled delivery date, as well as the overhead cost of the project. This study investigated the problem of delays in construction projects. The research focused on the combination of Building Information Modeling (BIM) and Last Planner System (LPS) together to measure the execution time of construction projects. The aim of this study was to determine whether using BIM and LPS together affect construction process delay differently than using BIM or LPS alone. The methodology of this study relied on data collection through administration of survey questionnaires to key players and participants at construction companies. Interviews were conducted with construction experts from four construction companies that used BIM and LPS individually in their system as case studies to verify and validate the findings. The outcomes of this survey will be helpful to construction practitioners to reduce delay in construction operations and to shorten projects duration
The regulation of labour and the state in the Sudan : a study of the relationship between the stage of social and economic development and the autonomy of labour relations law
No full textThe thesis is a study of labour regulation and the State in the
Sudan in the light of a general theoretical conception of labour law and
the State. The first Chapter defines the concepts of analysis that are
used throughout the study, isolates the "essential" properties of the
Capitalist State and Law from the historically concrete forms which they
assume in a particular society and distinguishes between processes which
influence development of the form of law and others which influence its
sociological development. Drawing on the analysis in Chapter I, Chapter
II exposes the inter-relationship between the Sudanese social formation,
State and Law and the implication of this inter-relationship for both the
form and substance of labour relations law. Chapters III, IV and V are
specific verifications of the hypothesis regarding the inter-relationship
between the State and labour relations law in the Sudan and that
regarding the development of the "substance" and "ideology" of law in
general.
The thesis considers law as an empirically-founded discipline.
But, it distinguishes between various types of empirical facts about law
corresponding with respective semi-autonomous social levels at which law
asserts its existence. The research method followed describes the
empirical facts about law at the particular level and, in order to
determine the epistemological significance of these facts, analytically
relates them to empirical facts at other levels. Wherever used in the
thesis the term "theory" signifies either this methodological procedure of
analysing the inter-connection of empirical facts at a certain level and
their inter-relation with other facts at other levels, or the substantive
generalizations about law which findings at these various levels would
allow.
I consider my application of this methodology to the study of
labour rela tions law, the historical dimension this application introduces
in socio-economic analysis of this law, the criticism of certain Marxist
and other sociological conceptions of law it enables, and the
socio-histor ical relativity of the "substance" and "ideology" of law it
reveals as original contributions to the knowledge of labour law. The
compilation and evaluation within the framework of the thesis of
empirical materials on industrial relations in the Sudan are likewise
original contribution to the knowledge of Sudanese "labour law" and
labour law in general

Grandes y pequeños ganaderos trashumantes en las sierras sorianas en el tránsito de la Edad Media a la Moderna
No full textEditada en la Universidad Carlos IIISe trata de llamar la atención en e este artículo sobre el papel de primera fila que jugaron los grandes señores de ganados en la actividad ganadera trashumante en el ámbito que abarcaba la cuadrilla mesteña de Soria durante los siglos XV y XVI. Para ello se establecen comparaciones entre el tamaño de sus rebaños y los de otros medianos y pequeños propietarios de la región, teniendo en cuenta entre otros indicios las noticias sobre sus ventas de lanas. Al mismo tiempo se profundiza en su caracterización desde el punto de vista sociopolítico, matizando algunas hipótesis que se han venido manejando para definir la base social mesteña y su evolución a lo largo del siglo XVI. Y por fin se repasan algunos aspectos referentes a la gestión de las explotaciones ganaderas trashumantes, que revelan la presencia de numerosos factores que hacían más rentables a las grandes frente a las medianas y pequeñas.Big sheep owners played a key role in nomadic sheeprearing in the Spanish region around Soria during the XVth. and XVIth. centuries. By using the volume of wool sales, the author compares the size of their flocks with those of other middle and small owners in the region and analyzes the owner’s sociopolitical profile, in order to qualify traditional hypotheses about the social basis of the «Mesta» and its evolution during the XVIth. Century. Lastly, some aspects of the management of sheeprrearing enterprises are examined, and its factors identified. In particular, the analyses focus on those aspects of sheeprearing that made big enterprises more profitable than the small ones.Publicad

Short-term alteration in voluntary feed intake after selenium supplementation in Angora goat kids
No full textThe objective of this study was to examine the effect of selenium (Se) supplementation on voluntary feed intake in Se-deficient Angora goat kids and its temporal relationship to alterations in the concentrations of thyroid hormones in plasma and the activity of glutathione peroxidase in serum. Angora goat kids were fed pelleted lucerne with a Se concentration of 20 mu g/kg of dry matter (DM) and treated orally with either Se (0.1 mg/kg of liveweight weekly, as sodium selenate) or deionised water. Supplementation with Se had no effect on DM intake measured over 21 days. Serum activity of glutathione peroxidase was increased by Day 1 of treatment (P < 0.001), plasma concentration of thyroxine was decreased by Day 21 of treatment (P < 0.01), and plasma concentration of triiodothyronine was unaffected by treatment. It is concluded that increased appetite is unlikely to be the primary mechanism involved in the response to Se supplementation in Angora goats.PT: J; CR: *SAS I INC, 1988, SAS US GUID STAT VER ARTHUR JR, 1993, AM J CLIN NUTR S, V57, P236 BUNK MJ, 1980, J NUTR, V110, P743 DONALD GE, 1993, AUST J EXP AGR ANIM, V33, P411 EWAN RC, 1976, J NUTR, V106, P702 HAFEMAN DG, 1974, J NUTR, V104, P580 HUSSEIN KSM, 1982, ACTA AGR SCAND, V23, P556 THOMPSON JN, 1969, J NUTR, V97, P335 THOMPSON KG, 1980, RES VET SCI, V28, P321 UNDERWOOD EJ, 1977, TRACE ELEMENTS HUMAN WALSH DM, 1993, INT J VITAM NUTR RES, V63, P188 WICHTEL JJ, 1995, IN PRESS J DAIRY SCI WICHTEL JJ, 1996, NEW ZEAL J AGR RES, V39, P111; NR: 13; TC: 1; J9: N Z J AGR RES; PG: 4; GA: UM341Source type: Electronic(1
