SUSY GUT Model Building

I discuss an evolution of SUSY GUT model building, starting with the construction of 4d GUTs, to orbifold GUTs and finally to orbifold GUTs within the heterotic string. This evolution is an attempt to obtain realistic string models, perhaps relevant for the LHC. This review is in memory of the sudden loss of Julius Wess, a leader in the field, who will be sorely missed.Comment: 24 pages, 14 figures, lectures given at PiTP 2008, Institute for Advanced Study, Princeton, to be published in the European Physical Journal

Collider aspects of flavour physics at high Q

This review presents flavour related issues in the production and decays of heavy states at LHC, both from the experimental side and from the theoretical side. We review top quark physics and discuss flavour aspects of several extensions of the Standard Model, such as supersymmetry, little Higgs model or models with extra dimensions. This includes discovery aspects as well as measurement of several properties of these heavy states. We also present public available computational tools related to this topic.Comment: Report of Working Group 1 of the CERN Workshop ``Flavour in the era of the LHC'', Geneva, Switzerland, November 2005 -- March 200

Using dairy value chains to identify production constraints and biosecurity risks

The dairy industry plays an important role in the economy and food security of India. A study of the dairy value chains was conducted in Punjab, India, to identify production constraints and biosecurity risks. Focus group discussions and key informant interviews were conducted during 2018–2019 with a total of 119 participants comprising veterinarians (41), paraveterinarians (15), veterinary academics (12), dairy farmers (46) and key informants (5). Input and output value chains were created, and potential risk nodes were identified that could facilitate the transmission of pathogens between animals, farms and villages. The majority of the participants were male (93%), middle-aged (68%) or worked in rural areas (75%). Most of the farmers self-cultivated their green fodder (82%), used the wheat straw from their own fields (60%) but purchased commercial feed (63%). Artificial insemination was used by 85% of farmers for cattle, but only 68% for buffaloes. Most of the farmers (76%) reported getting their animals vaccinated against foot-and-mouth disease and hemorrhagic septicemia. Animals were sold and purchased without any health certification and testing in most cases. Adoption of biosecurity measures by farmers and the use of personal protective equipment by veterinary personnel were very low. We recommend conducting epidemiological studies to further characterize the identified risk nodes, training of veterinary practitioners and farmers to ensure adequate biosecurity practices and the appropriate use of personal protective equipment. © 2020 by the authors.
