<p>The Netherlands is a densely-populated country, with many rivers and roads. As a result, there are many intersections between roads and waterways, and these intersections are heavily used. Movares is a Dutch engineering consultancy and we can draw on over 100 years’ experience with a wide range of bridges and viaducts. We are among the Netherlands’ leading consultants in the field of movable bridges. Our knowledge and experience put us in a perfect position to look after bridges from initial design through to end of service life.</p><p>Many Dutch bridges – both movable and fixed – were built in the 1950s and 1960s, and were not designed for today’s increased, heavier traffic. They are showing symptoms of fatigue and/or no longer conform (demonstrably) to current requirements. As a result, they need to be replaced. The availability of infrastructure is of great economic importance</p><p>At the same time, safety must be guaranteed. Our philosophy: “If it ain’t broke, don’t fix it!” Our ap-proach – the BridgeDoctor® – allows us to establish the condition of a bridge with the aid of a rapid analysis. In many cases, we can use smart measures to extend the life of a bridge, allowing it to remain in service for several more decades.</p><p>By an inventory based on available information. The aim is to gain insight into the status of the bridges now, but also in the future. On this basis it is possible to predict when the bridge needs to be replaced or, and of course, how and when to intervene constructively. This inventory provides quick answers to questions such as: which bridge is constructively safe and which bridge should be tackled first?</p><p>Maintenance also prevents emergency repairs and saves a lot of money (emergency repair = costly and timely maintenance can lead to less maintenance.</p>

The purpose of this paper is to establish as clearly as possible the status of the genus Aneristus Howard, to assemble all the available information concerning the habits and host-relationships of its members, and to make known three new species from the West Indies. So far as known all the species of Aneristus are primary parasites of the non-diaspine Coccidae or soft scale insects and are of great economic importance.

This article shows how bargaining on the conflicting issues of fighting unemployment and increasing competitiveness has evolved. It offers an empirical insight into the degree to which the national framework agreements that form part of the now famous Dutch polder model are implemented. At the national level framework agreements are set up and recommendations are made on a wide range of issues. It is shown that these are then interpreted and partly adopted by negotiators at lower collective bargaining levels. At company level, three cases illustrate differences in the degree to which companies implement the outcomes of collective agreements: from ‘dedicated follower’ to ‘rebels with a cause'. Looking at the evidence, it seems the Dutch have experienced a form of organised decentralisation.

Abstract The sting nematode, Belonolaimus spp., is one of the most destructive nematode pests of turfgrass and attacks a wide range of monocotyledonous plants and gymnosperms, including vegetables, legumes, cereals, etc. This chapter includes information on: geographical distribution; host ranges; symptoms; biology and life cycle; ecology; physiological races; economic importance; invasiveness; pest risk analysis; movement and means of dispersal; management measures; and detailed account of diagnosis procedures, such as morphological, biochemical, cytogenetic and molecular characterization, of Belonolaimus species.

Curcumin is a compound extracted from the Curcuma longa L, which possesses a wide range of pharmacological effects. However, few studies have collected scientific evidence on its dual effect on angiogenesis. The present review gathered the fragmented information available in the literature to discuss the dual effect and possible mechanisms of curcumin on angiogenesis. Available information concerning the effect of curcumin on angiogenesis is compiled from scientific databases, including PubMed and Web of Science using the key term (curcumin and angiogenesis). The results were reviewed to identify relevant articles. Related literature demonstrated that curcumin has antiangiogenesis effect via regulating multiple factors, including proangiogenesis factor VEGF, MMPs, and FGF, both in vivo and in vitro, and could promote angiogenesis under certain circumstances via these factors. This paper provided a short review on bidirectional action of curcumin, which should be useful for further study and application of this compound that require further studies.

The earthwormPontoscolex corethrurus(Müller, 1857) is reported for the first time from Punjab, India. This species was first described by German naturalist Fritz Müller in 1857 from Santa Catarina state of Brazil. It is commonly found in gardens, cropland and fallowlands. It tolerates wide range of climatic and edaphic factors due to its endogeic ecological category.P. corethrurushas high efficiency for organic matter assimilation and has ability to live in new habitat due to which it can survive even in very poor soil. The life cycle of this species is well documented and this species has economic importance due to its use in waste management.

Abstract Meloidogyne chitwoodi and M. fallax have been important nematode problems in arable farming in the Netherlands and Belgium ever since their detection in the 1980s. Their quarantine status and the damage inflicted on product quality in important cash crops such as potato, carrots, black salsify and gladiolus has increased drastically the need for integrated nematode management strategies that prevent yield losses and further spreading. This chapter elaborates on the economic importance, host range, distribution, symptoms of damage, biology and life cycle, interactions with other nematodes and pathogens, recommended integrated nematode management (prevention, inventory, crop rotation and supporting measures), and management optimization of M. chitwoodi and M. fallax. Future research requirements are also mentioned.

In this chapter the studies made on an international level in line with the zero waste goal with recycling logistics in green logistics vision are examined. Businesses acting sensitive to the changing environmental conditions, adopting the zero waste with recycling logistics in green logistics vision in line with their development goals are within the contemporary production targets. In a global view, the goal is both creating a livable world and reducing the life cycle costs. In this regard, the chapter researches the status of the recycling logistics to create awareness on the role and importance of the logistics services and operators in the waste industry. Also, to scan the available literature with the reported applications in the less-developed countries in line with the zero waste goal with green logistics vision and to emphasize the importance of these applications.

This book presents a remarkable collection of letters from Queen Wilhelmina of the Netherlands (1880-1962) and her governess, Elizabeth Saxton Winter (1855-1936), an Englishwoman. The earliest letters are those of a child, sent to Miss Winter when she was on holiday in England, but after Wilhelmina's education was finished in 1896 and she had no more need of a governess, she continued to write to Winter weekly. Her long letters cover a wide range of subjects: including her perspective on people and events, encounters with famous individuals, kings and emperors, but also sad times and loneliness, her belief in the Almighty, and above all, her development to her role as queen - her inauguration was in 1898 - and the high seriousness with which she regarded her duties. The resulting volume offers unprecedented insight into her life as child of her mother queen-regent Emma, as queen, as wife of prince Hendrik and as mother of princess Juliana.

Purpose The aim of this study was to develop a tool to gain insight into the daily experiences of new hearing aid users and to shed light on aspects of aided performance that may not be unveiled through standard questionnaires. Method The tool is developed based on clinical observations, patient experiences, expert involvement, and existing validated hearing rehabilitation questionnaires. Results An online tool for collecting data related to hearing aid use was developed. The tool is based on 453 prefabricated sentences representing experiences within 13 categories related to hearing aid use. Conclusions The tool has the potential to reflect a wide range of individual experiences with hearing aid use, including auditory and nonauditory aspects. These experiences may hold important knowledge for both the patient and the professional in the hearing rehabilitation process.
