A 40 kg crossbred calf of one month age was presented to the Institute Referral Polyclinic, with a history of dysuria, stranguria along with a fluctuant swelling in the mid-perineal region. On physical examination, a diverticulum was observed which on aspiration revealed urine. It was reported that urine outflow was from a tiny orifice at the proposed natural site of the vulva.

In this introductory part of a two part series of articles on multi-carrier techniques, a background to Orthogonal Frequency Division Multiplex (OFDM) is provided, as well as a detailed historical perspective of multicarrier systems, identifying their most critical design aspects. These systems exhibit numerous attractive features, rendering them eminently eligible for employment in next-genera...

Environmental gradients represent an ideal framework for studying adaptive variation in the life history of plant species. However, on very steep gradients, largely contrasting conditions at the two gradient ends often limit the distribution of the same species across the whole range of environmental conditions. Here, we study phenotypic variation in a winter annual crucifer Biscutella didyma p...
