    We tested several models in which the Standard Model (SM) gauge group is extended by an additional U(1) gauge symmetry, against available electroweak precision data to impose limits on the mass of the neutral Z' boson, M_Z', predicted in all such models, and on the Z-Z' mixing angle, theta_ZZ', at 95% C.L. We found lower limits on M_Z' of order 1 TeV in most cases, while theta_ZZ' was found to be constrained to very small values.Comment: Format fixed, 5 pages, 2 figures, Talk given at the 17th International Conference on Supersymmetry and the Unification of Fundamental Interactions (SUSY09), Boston, MA, USA, 5-10 June 2009, to be published in the conference proceedings (AIP

    Z' Searches: From Tevatron to LHC

    The CDF collaboration has set lower limits on the masses of the Z' bosons occurring in a range of E_6 GUT based models. We revisit their analysis and extend it to certain other E_6 scenarios as well as to some general classes of models satisfying the anomaly cancellation conditions, which are not included in the CDF analysis. We also suggest a Bayesian statistical method for finding exclusion limits on the Z' mass, which allows one to explore a wide range of the U(1)' gauge coupling parameter. This method also takes into account the effects of interference between the Z' and the SM gauge bosons.Comment: 5 pages. Talk given at the XXIInd Rencontres de Blois, Loire, France, 16-20 July 201

    Studies on the influence of islamic law in Indonesia can be one basis for muslims to define the future strategy of the Indonesian nation closer or familiarizing with Islamic law that has the effect of legal politic in Indonesia. At least it show sthat the influence of the process of Islamization of a society is nothing that can be completed immediately, but the center of attention is focused on the legal position of Islam can influence on legal politic in Indonesia whic his polarized in the establishment of the legal system. Political policy in the law not only in legal proceedings that will be and are being enforced but includes also the law that have occurred, have practical purposes to allow positive legislation can be better formulated so as to provide guidance not only on legislation but also to the Courts as an organizer or as an implementing decision. This has been experienced by the people of Indonesia since the era Dutch colonial that changed significantly when the Indonesian republic independent on 17 of August 1945, because they have to adjust in accordance with applicable law and the constitutional foundation the state ideology of Pancasila and the Constitution of 1945 or a law that is built upon the activity and creativity based upon ideals that is sourced on the cultural values of the nation which has long since evolved to the present

    This study aimed to describe, analyze budget planning and to identify, analyze the supporting and obstacle factors of the Public Service Agency/ BLU pattern USAge from good governance perspective. It used qualitative approach case study. The obstacle factors are incompetent human resource on IT, lacking knowledge on the budget cycle, unclear manual procedure, and short time budgetmaking. Supporting factors are Rector's program, increase graduate and decrease undergraduate students number, leader motivation on budget planning, and convenient facilities

    Purpose/Background. This study reports the degree of burden and the proportion at risk for depression among individuals who provide care to visually impaired patients. Study Design. This is clinic-based, cross-sectional survey in a tertiary care hospital. Methods. Caregivers were considered unpaid family members for patients whose sole impairment was visual. Patients were stratified by vision in their better seeing eye into two groups: Group 1 had visual acuity between 6/18 and 6/60 and Group 2 were those who had 6/60 or worse. Burden was evaluated by the Burden Index of Caregivers and the prevalence of being at risk for depression was determined by the Center for Epidemiologic Studies Depression scale. Results. 236 caregivers of 236 patients were included. Total mean BIC scores were higher in Group 2. Female caregivers, caregivers providing greater hours of care, and caregivers of patients who have not completed vision rehabilitation programs are at higher risk for depression
