The soybean rust caused by Phakopsora pachyrhizi is considered the main soybean disease and consequently the appropriate selection and the use of spraying equipment are vital for its control. The aim of this study was to evaluate the performance of aerial application equipment for soybean rust control. It was used: Micronair AU 5000 at 10 L ha-1 (with oil) and at 20 L ha-1 (without oil); Stol ARD atomizer at 10 and 20 L ha-1 (both with oil) and Spectrum (electrostatic) at 10 L ha-1 (without oil). The adjuvant was cotton oil (1.0 L ha-1) with emulsifier (BR 455) at 0.025 L ha-1. The field trial was set up at the 3rd fungicide application, when f four replications of each treatment. There were no statistical differences among treatments related to fungicide deposits by at a Confidence Interval of 95%. It was observed that the best results were obtained with Micronair (10 L ha-1 with oil), Stol (20 L ha-1 with oil) and electrostatic system at 10 L ha-1 with the lowest relative humidity (64%).

Purpose – The purpose of this paper is to analyse the adoption of a multimodal medication management system (MMS) targeted on older people and home care professionals. The paper aims to describe the expectations of the system and the user experience findings from an empirical qualitative field trial. The field trial results are used to discuss how MMSs should be designed in order to improve adherence to medications. Design/methodology/approach – The paper suggests that building a multimodal medicine management system targeted on both older users and home care professionals brings many benefits over electronic medicine dispenser systems or general reminder systems. The research process uses an iterative prototyping approach including phases of requirements analysis and concept design, prototype building and evaluation in a field trial. Findings – The study demonstrates how a system that merely satisfied users during the prototype building phase does not necessarily succeed as well as expected in the field trials. It would be important to consider reasons for medication non-adherence and non-technology factors influencing willingness to adopt new assistive devices in order to promote diffusion of new MMSs at home. The paper also discusses how the different persuasive functionalities of the system addressed patient-centred factors influencing non-adherence and how they could be addressed. Research limitations/implications – This study has some limitations. The actual adherence to medications was not measured. However, in the future, it will be important to study how the MMSs influence medication adherence. Also, the user experiences of the home care professionals were not studied in the field trials. Home care professionals who were involved in the user studies and trials merely estimated the value for their patients and not for themselves. Originality/value – This paper analyses design issues relevant when designing systems to help older people manage their medications.

This paper presents the results obtained from a research project that focused on investigating the feasibility of using cellulose fibers to cure bridge soffit repairs. The use of cellulose as a curing method involves spraying wet cellulose on the freshly applied shotcrete. By adhering to the shotcrete, the wet cellulose maintains the relative humidity within the shotcrete above the level required to sustain hydration of the cementing materials. Twelve 1000 mm × 1000 mm × 130 mm panels were prepared using two types of shotcrete materials and cured using either air curing, curing compound, misting and curing compound, or cellulose. The results showed that the cellulose could be applied to shotcrete in an overhead position and remained adhered to the shotcrete for 28 days. At the end of the curing period, the cellulose was easily removed from the shotcrete surface by means of a hand shovel. Cellulose-cured panels showed the least evidence of surface cracking. Also, the use of cellulose did not have any negative effects on the temperature of the shotcrete.Key words: bridge repair, shotcrete, silica fume, accelerator, polypropylene fibers, curing, cellulose, heat of hydration, adhesion.

The Relationship

This study investigated the relationship between the intake of antioxidant nutrients and the suffering of cataracts in 177 institutionalized elderly people (61 men and 116 women) aged ≥ 65 years. Dietary intake was monitored for 7 consecutive days using a "precise individual weighing" method. Subjects, who during their earlier years were exposed by their work to sunlight, had a greater risk of suffering cataracts (OR = 3.2; Cl: 1.1–9.3, P < 0.05) than those who worked indoors. A relationship was found between increased vitamin C intake and a reduced prevalence of cataracts (i.e., when comparing those above P95 for vitamin C intake with those below P5; (OR = 0.08; Cl: 0.01–0.75, P 0.05). Among subjects with cataracts, 12.1% had vitamin C intakes of < 61 mg/day (P10) and only 2.2% had intakes of > 183 mg/day (P95) (p < 0.01). Subjects who consumed > 3290 μg/day (P95) of lutein were less likely to have cataracts (OR = 0.086; Cl: 0.007–1.084; p < 0.05) than those whose consumption was < 256 μg/day (P5). In men, high intakes of zeaxanthin seemed to provide a protective effect against the problem (OR = 0.96; Cl: 0.91–0.99; p < 0.05). The results suggest an association exists between exposure to sunlight and the development of cataracts, and that vitamin C, lutein, and zeaxanthin offer some protection against this disorder.

Typology Of Care

This paper presents the EUROFAMCARE study findings, examining a typology of care situations for family carers of older people, and the interplay of carers with social and health services. Despite the complexity of family caregiving situations across Europe, our analyses determined the existence of seven “caregiving situations,” varying on a range of critical indicators. Our study also describes the availability and use of different support services for carers and care receivers, and carers’ preferences for the characteristics of support services. Our findings have relevance for policy initiatives in Europe, where limited resources need to be more equitably distributed and services should be targeted to caregiving situations reflecting the greatest need, and organized to reflect the preferences of family carers.

Depth Interviews

Background: Quantitative studies in several European countries showed that 10–20% of older people have or have had a wish to die. Aims: To improve our understanding of why some older people develop a wish to die. Methods: In-depth interviews with people with a wish to die (n = 31) were carried out. Through open coding and inductive analysis, we developed a conceptual framework to describe the development of death wishes. Respondents were selected from two cohort studies. Results: The wish to die had either been triggered suddenly after traumatic life events or had developed gradually after a life full of adversity, as a consequence of aging or illness, or after recurring depression. The respondents were in a situation they considered unacceptable, yet they felt they had no control to change their situation and thus progressively “gave up” trying. Recurring themes included being widowed, feeling lonely, being a victim, being dependent, and wanting to be useful. Developing thoughts about death as a positive thing or a release from problems seemed to them like a way to reclaim control. Conclusions: People who wish to die originally develop thoughts about death as a positive solution to life events or to an adverse situation, and eventually reach a balance of the wish to live and to die.
