F. Sopeña, C. Maqueda, and E. Morillo. 2009. Controlled release formulations of herbicides based on micro-encapsulation. Cien. Inv. Agr. 36(1): 27-42. Annual worldwide losses to weeds are estimated to comprise approximately 10-15% of attainable production among principal food sources. Worldwide consumption of herbicides represents 47.5% of the 2 million tons of pesticide consumed each year. How...

Accurate and correct performance of controller in cruise control systems is important. Hence, in such systems, controller should optimize itself against noise and probable changes in system dynamic. As a matter of fact, in this article three approaches have been conducted to-ward this purpose: MIT, direct estimation and indirect estimation. These approaches are used as controllers to track refe...

herbicide toxicities are considered as an important issue in public health programs of developing countries. this investigation aims at studying epidemiologic toxicities caused by paraquat herbicide and comparing factors influencing these patients’ causality in kermanshah imam khomeini hospital. in a descriptive-survey study, 9 patients poisoned by paraquat herbicide were considered statistical...

This paper investigates residents’ preferences of investment in cruise tourism, taking its externalities into full account. The research involved data collection in the port of call of Messina (Sicily, Italy), during the peak cruise season in 2011. A mixed generalized ordered logit analysis, based upon a correspondence analysis, is run to examine what factors influence residents’ perceptions ab...

Bentazon, C 0 2-Assimilation, Inhibition of Photosynthesis, Photosystem 2-Herbicide, Shade-Type Adaptation of Chloroplasts The inhibition of photosynthetic C 0 2-assimilation and of the variable chlorophyll fluorescence as well as uptake and transport of 14C-labelled bentazon and the possibilities for a herbicideinduced shade-type modification of the photosynthetic apparatus were investigated i...

Several studies have expressed concerns about the effects of gene flow from transgenic herbicide-resistant crops to their wild relatives, but no major problems have been observed. This review describes a case study in which what has been feared in transgenics regarding gene flow has actually changed biodiversity and people's lives. Nontransgenic imidazolinone-resistant rice (IMI-rice) cultivars...

Weed infestations in agricultural systems constitute a serious challenge to agricultural sustainability and food security worldwide. Amaranthus palmeri S. Watson (Palmer amaranth) is one of the most noxious weeds causing significant yield reductions in various crops. The ability to estimate seed viability and herbicide susceptibility is a key factor in the development of a long-term management ...

BACKGROUND Being highly contagious by person-to-person transmission, varicella can easily spread within the multinational population of a cruise ship and into communities ashore. The aim of the study was to report the prevalence of varicella infections in a fleet of cruise ships during a two-year period and to discuss measures to prevent and contain shipboard outbreaks. MATERIAL AND METHODS A...

BACKGROUND Understanding and managing the evolutionary responses of pests and pathogens to control efforts is essential to human health and survival. Herbicide-resistant (HR) weeds undermine agricultural sustainability, productivity and profitability, yet the epidemiology of resistance evolution - particularly at landscape scales - is poorly understood. We studied glyphosate resistance in a maj...
