For the HERA-B experiment a processor farm for the third level trigger and full event reconstruction is planned. It will consist of more than 100 processor nodes, receiving data via high speed data links from a switching network. In 1996, a VME-based system (test farm) was built to test a possible implementation. In parallel, investigations of alternative, non-VME-based solutions for the proces...

The level 2 trigger on charged particles (L2C) of the NA48 experiment features powerful capabilities for implementing complex triggering algorithms in real-time software. These algorithms may involve track reconstruction, vertex, invariant mass or transverse momentum computation, etc. After a brief outline of the L2C architecture, this paper describes the salient features of the I/O and process...

Farm restructuring during transition is often defined as a combination of the change of the internal organization of a farm and the change in farm size, following the liberalization of the economy and the privatization of property rights. Following this definition, farm restructuring involves downsizing farm units and reorganizing management-ownership-workforce relationships. This paper tries t...

This study analyzed the impact of off-farm earnings on the intensity of adoption of improved maize varieties and the productivity of maize farming in Uganda in the years 2005/06 and 2009/10. Summary statistics show significantly higher adoption intensity and expenditure on purchased inputs among households with off-farm income relative to their counterparts without off-farm income. Households w...

Entrepreneurship in agriculture is a phenomenon that growing importance with the changing framework conditions for agricultural production and has led to heterogeneity farm business development paths. To understand this better, classification scheme strategic entrepreneurial choices developed family farmers. The are scrutinized reduction, continuation, expansion, diversification, dual strategy ...

Rural households in developing countries often depend on agriculture for their livelihoods. However, many also pursue off-farm economic activities either to complement farm income or because they lack access agricultural land. employment is informal and temporary. Searching jobs can be associated with high transaction costs, which may a constraint some households’ participation employment. The ...

PURPOSE Operating or riding on farm equipment is one of the leading causes of farm-related injuries and fatalities among children and adolescents. The aim of this study is to examine environment, crash, vehicle, and occupant characteristics and the probability of injury, given a crash, in youth under age 18 on farm equipment. METHOD Data from the Departments of Transportation on farm equipmen...

To quantify the respiratory disease burden among agricultural workers, we examined the 1988-1998 National Center for Health Statistics (NCHS) "Multiple Cause of Death Data" and the 1988-1994 Third National Health and Nutrition Examination Survey data (NHANES III). Proportionate mortality ratios (PMRs) were determined for 11 respiratory conditions among 6 agricultural groups: crop farm workers, ...

Using longitudinal panel data from the Western Chitwan Valley of Nepal, this study investigates the impact of the use of modern farm technologies on fertility transition-specifically, the number of births in a farm household. Previous explanations for the slow pace of fertility transition in rural agricultural settings often argued that the demand for farm labor is the primary driver of high fe...

The European Union (EU) is among the largest beef producers in world. Besides economic turnover, production causes adverse environmental impacts such as climate change. sector known for high heterogeneity systems, partly explained by different natural and conditions. This study assesses environmental, social, performances of three typical systems EU at farm level. optimization model FarmDyn use...
