Calfhood diseases have a major impact on the economic viability of cattle operations. This is the first in a three part review series on calf health from birth to weaning, focusing on preventive measures. The review considers both pre- and periparturient management factors influencing calf health, colostrum management in beef and dairy calves and further nutrition and weaning in dairy calves.

Micro and nano electro mechanical systems (MEMS and NEMS) have emerged as a technology that integrates micro/nano mechanical structures with microelectronics, mainly for sensing and actuation applications. MEMS and NEMS sensor systems that can operate in the presence of high temperatures, corrosive media and/or high radiation will reduce weight, improve machine reliability and reduce cost in st...

Let $G*H$ be the product $*$ of $G$ and $H$. In this paper we determine the rth power of the graph $G*H$ in terms of $G^r, H^r$ and $G^r*H^r$, when $*$ is the join, Cartesian, symmetric difference, disjunctive, composition, skew and corona product. Then we solve the equation $(G*H)^r=G^r*H^r$. We also compute the Wiener index and Wiener polarity index of the skew product.

We report on work in progress on extracting lexical simplifications (e.g., “collaborate” → “work together”), focusing on utilizing edit histories in Simple English Wikipedia for this task. We consider two main approaches: (1) deriving simplification probabilities via an edit model that accounts for a mixture of different operations, and (2) using metadata to focus on edits that are more likely ...

The constantly changing business environment has forced many organizations to move away from focusing on individual tasks and functions to focusing on more integrated and coordinated ways of work. Higher-level business and information systems (IS) education is also in a state of change, as the traditional curriculum does not coincide with business realities. The mission of IS is shifting from d...

Solid waste management (SWM) is an increasingly complex task, absorbing a huge amount of resources and having a major environmental impact. Computerized systems based on operations research techniques can help decision makers to achieve remarkable cost savings as well as to improve waste recovery. Nevertheless, the literature is quite scattered and disorganized. The objective of this paper is t...
