OBJECTIVES Investigating relationships between potential occupational risk factors and lymphoid malignancy (LM). METHODS We conducted a multicenter hospital-based case-control study in France between 2000 and 2004, including 824 incident cases of non-Hodgkin lymphoma (NHL), Hodgkin lymphoma (HL), multiple myeloma, and "lymphoproliferative syndrome" and 752 frequency-matched controls. Data wer...

A multiperiod model based upon a multicriteria objective function has been developed for a representative area of the Guadalquivir Valley, dividing the irrigated area into homogeneous types of farming as identified by cluster analysis. The model was applied to different future scenarios with a time horizon of 10 years and several different farming environments. A set of eight sustainability ind...

since time immemorial, iranian women have played a pivotal role in agriculture, the largest industry contributing to rural livelihoods. hence, the present study was conducted in tafresh area of iran to examine factors influencing participation of rural women in mixed farming activities in 1999.this was a descriptive- correlation research project in which a total number of 300 rural women were s...

Organic farming is increasingly recognized as a prototype for sustainable agriculture. Its guidelines ban the use of artificial fertilizers. However, organic farms may import nutrients from conventional farming through material exchanges. In this study, we aimed at estimating the magnitude of these flows through the quantification of nitrogen, phosphorus and potassium inflows from conventional ...

BACKGROUND/OBJECTIVES The purposes of this study were to compare total energy expenditure (including PAL and RMR) of Korean farmers between the farming season and off farming season and to assess the accuracy of estimated energy requirement (EER) prediction equation reported in KDRIs. SUBJECTS/METHODS Subjects were 72 Korean farmers (males 23, females 49) aged 30-64 years. Total energy expend...

To date numerous results on innovation research have been published, however, the literature on innovation does not offer conclusive findings and guidelines for practice. The research and practice of innovation are fragmented and centered on specific cases. The literature does not present a unified theory of innovation. Innovation in any domain could be enhanced by principles and insights from ...

In agent based models, the agents are usually platforms (individual soldiers, tanks, helicopters, etc.), not military units. In the Sandis software, the agents can be platoon size units. As there are about 30 soldiers in a platoon, there is a need for strength distribution in simulations. The contribution of this paper is a conceptual model of the platoon level agent, the needed mathematical mo...

The aim of this study was to develop a pilot plant for the production of M. barbatus seed through artificial reproduction technology for possible use in aquaculture and repopulation of nursery areas. The study involved various phases: setup of the pilot plant, sourcing of M. barbatus specimens and their transplantation to an offshore long-line farm; production of live food (phytoplankton); sele...

Production of foreign molecules in transgenic plants is anticipated to be an alternative to already established, microbial or animal expression systems with lower production costs. This article reviews the different technologies and approaches currently used to produce economically interesting molecules in plants or plant cell cultures, to evaluate their technical feasibility and economic impli...

Land use change may influence many natural phenomena and ecological processes, including runoff, soil erosion, sedimentation and soil conditions. Decreasing of forest area in the North of Iran is one of the critical problems in recent years. The aims of this study are to detect land use changes between 1967 to 2002 using satellite images of Land Sat 7 ETM+ (2002), aerial photos and digital topo...
