During large Q fever outbreaks in the Netherlands between 2007 and 2010, dairy goat farms were implicated as the primary source of human Q fever. The transmission of Coxiella burnetii to humans is thought to occur primarily via aerosols, although available data on C. burnetii in aerosols and other environmental matrices are limited. During the outbreak of 2009, 19 dairy goat farms and one dairy...

1. SMART FARMS SET PERFORMANCE GOALS There is an old saying that you can’t get to your destination unless you know where you are going. Many farms that start on the path to milking excellence don’t make it because they don’t have clear quality goals for their farms. Many dairy farms consistently produce high quality milk. In 1998, over 1,800 Wisconsin dairy farms had average bulk tank somatic c...

Purpose This study examines the adoption drivers of scale-appropriate mechanization in Nepal's maize-based farming systems. The authors also assess contribution to United Nations Sustainable Development Goals (SDGs) zero hunger (SDG2) and no poverty (SDG1). Design/methodology/approach Propensity score matching doubly robust inverse probability-weighted regression adjusted methods were applied e...

The constraints that cooperative and non-cooperative dairy farms face in expanding milk production have been reported based on a field study on some cooperative and non-cooperative dairy farms in the state of West Bengal. The study has shown that non-cooperative farms face major constraints and high severity compared with cooperative farms in expanding milk production. Also important is that mo...

Rapid population growth, urbanization and rising incomes will present an unprecedented opportunity for growth of commercial agriculture and agribusiness in coming years. The value of food consumed in urban areas is set to expand by four times to 2030, but given evidence of a continuing decline in competitiveness much of this could be sourced from imports even in countries with an apparent compa...

BACKGROUND Livestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA) has a wide host range and is transmissible to humans, especially to those with close contact to colonized animals. This study presents the first data on the occurrence of MRSA in farm workers and livestock farms (pig, cattle and poultry) in the federal state of Mecklenburg-Western Pomerania in northeast German...

Using separation logic, this paper presents three Hoare logics (corresponding to different notions of correctness) for the simple While language extended with commands for heap access and modification. Properties of separating conjunction and separating implication are mechanically verified and used to prove soundness and relative completeness of all three Hoare logics. The whole development, i...

In the decade of the 1990s, formal methods have progressed from an academic curiosity at best, and a target of ridicule at worst, to a point where the leading manufacturer of microprocessors has indicated that its next design will be formally veri ed. In this short paper, I sketch a plausible history of the developments that led to this transformation, present a snapshot of the current state of...

(51) We apply 8I to (51) and prove (49). P and t are deened inductively over the structure of sequent trees. In the base case, we have P and t such that (47) is 8x (T(x) T(x)). Consider now the step case. We write (47) in the following form. (52) where P x 1 ; :::; x n ] does not contain occurrences of T. We assume the hypotheses of (52) and derive Tac(x 1) ^ ::: ^ Tac(x m). From (29) we obtain...
