    Description: The behaviour of water waves over periodic beds is considered in a two-dimensional context and using linear theory. Three cases are investigated: the scattering of waves by a finite section of periodic topography; the Bloch problem for infinite periodic topography; and sloshing motions over periodic topography confined between vertical boundaries. Connections are established between these problems. A transfer matrix method incorporating evanescent modes is developed for the scattering problem, which reduces the computation to that required for a single period, without compromising full linear theory. The problem of the existence of Bloch waves can also be posed on a single period, leading to a close relationship between it and the scattering problem. Sloshing motions over periodic beds, which may be regarded as special cases of the Bloch problem, are also found to have a significant connection with wave scattering. Integral equations methods allied to the Galerkin approximation are used to resolve the three problems numerically. In particular, the full linear solution for Bragg resonance is presented, allowing the accuracy of existing approximations to this phenomenon to be assessed. The selection of results given illustrates the main features of the work.

    Notes: : Most herbicides applied to crops are adsorbed by plants or transformed (degraded) in the soil, but small fractions are lost from fields and either move to streams in overland runoff, near surface flow, or subsurface drains, or they infiltrate slowly to ground water. Herbicide transformation products (TPs) can be more or less mobile and more or less toxic in the environment than their source herbicides. To obtain information on the concentrations of selected herbicides and TPs in surface waters of the Midwestern United States, 151 water samples were collected from 71 streams and five reservoir outflows in 1998. These samples were analyzed for 13 herbicides and 10 herbicide TPs. Herbicide TPs were found to occur as frequently or more frequently than source herbicides and at concentrations that were often larger than their source herbicides. Most samples contained a mixture of more than 10 different herbicides or TPs. The ratios of TPs to herbicide concentrations can be used to determine the source of herbicides in streams. Results of a two-component mixing model suggest that on average 90 percent or more of the herbicide mass in Midwestern streams during early summer runoff events originates from the runoff and 10 percent or less comes from increased ground water discharge.

    Notes: Abstract In view of the evidence indicating several potential benefits of high intakes of conjugated linoleic acid (CLA) on human health, an experiment was conducted to examine the effects of the diet of beef cattle on the total CLA concentration in muscle and subcutaneous fat. High-concentrate [steers consumed 515 g concentrates and 485 g grass silage kg−1 dry matter (DM) for 8 weeks followed by 887 g concentrates and 113 g grass silage kg−1 DM for 14 weeks until slaughter] and high-forage (steers consumed 803 g grass silage and 197 g concentrates kg−1 for 8 weeks followed by grass silage only for 10 weeks and then grazed perennial ryegrass-based pasture for 23 weeks until slaughter) treatments were imposed on 48 steers, which were crosses of continental beef breeds (initially 414 kg live weight) The concentrates were based on barley, extracted soyabean meal, molassed sugarbeet pulp and maize meal. The silages were of medium to low digestibility and contained 117–137 g crude protein kg−1 DM and 83–158 g ammonia-N kg−1 total N. The pasture was of high quality and contained 168 g crude protein, 234 g acid-detergent fibre and 222 g water-soluble carbohydrate kg−1 DM. Samples of muscle were taken post slaughter from the m. semimembranosus, m. gluteobiceps, m. longissimus and m. deltoideous muscles, and subcutaneous fat was taken from over the m. longissimus. Concentrations of total CLA in the tissues were for the high-concentrate and high-forage treatments, respectively (mg 100 g−1 fresh tissue), m. gluteobiceps 18 and 47 (s.e. 3·5); m. semimembranosus 9 and 20 (s.e. 1·6); m. longissimus 15 and 35 (s.e. 3·2), m. deltoideous 20 and 59 (s.e. 4·3); subcutaneous fat 584 and 1975 (s.e. 138·7). It is concluded that muscle and subcutaneous fat tissue from grass-fed cattle contained three times as much CLA as those from concentrate-fed cattle, and that the consumption of beef from grass-fed cattle should be effective in increasing the intake of CLA by humans.

    Notes: The skill of chairing meetings is a key one that can greatly influence personal and organisational effectiveness. However, it is often assumed that people know how to handle meetings by a process of osmosis. Sometimes this is justified but often not, and standards of chairing vary widely. In this article the basic skills of chairing meetings are identified, with emphasis being on the ways in which they can be systematically developed. This includes analysis of interactions at meetings, particularly those interactions involving the chair. The difference between procedural, process and substantive contributions is also examined and the importance of these distinctions, particularly for whoever is chairing a meeting.

    Notes: The problems of operating employee appraisal schemes effectively are identified in this two-part article. Appraisal of formal appraisal schemes suggests that most do not operate satisfactorily. Multipurpose schemes can be cumbersome and include conflicting objectives. The feedback process can also cause major problems. Such problems can be exacerbated with schemes of 360-degree appraisals, according to their complexity and the role conflicts that they precipitate. In the second part of the article, the level of organisational investment needed for schemes to operate effectively is considered. The ways in which competencies, self-appraisal and peer audit can be constructively used are examined. The crucial link between formal and informal appraisal processes is considered as is the importance and skills involved in an informal appraisal. Finally, the way in which the training needs of appraisees need to be realistically identified and assessed is also explained.

    Notes: This paper describes a research project funded by the Engineering and Physical Sciences Research Council. Twenty case-study companies operating across a range of industrial sectors participated in the project. Sectors chosen for the development of these architectures were those where the use of the traditional manufacturing resource planning (MRPII) model is not the optimum operating solution. In particular, the paper describes the process mapping and analysis approach applied to the study of a sector-based group of apparel manufacturing companies who collaborated in the research. The planning issues that confront the companies, the control solutions they employ in response to their present commercial environment as they seek to address the changing demands being made of the industry are outlined. A generic planning and control reference architecture developed from the study for the apparel sector is presented.

    Notes: Workplace agility is emerging as the highest priority for the providers of workplace services and infrastructure. 'Agility' means continuously improving work and the infrastructure that enables it. An agile workplace is onethat is constantly transforming, adjusting and responding to organisational learning. Agility requires a dynamic relationship between work and the workplace and the tools of work. In that relationship the workplace becomes an integral part of work itself - enabling work, shaping it and being shaped by it. This paper focuses on defining workplace agility and discusses the triggers that prompt agile workplace making. Strategies for creating agile workplaces are discussed and the idea of 'rehearsing' change is introduced. This paper is excerpted from 'The Agile Workplace', which introduces the business and technology forces that drive and enable agile work. The report includes chapters about change management, organisational responsibilities and performance metrics.

    Notes: Natural fatigue crack formation and growth were studied in notched Al–Cu alloy coupons through high-resolution SEM fractography. The experiments were conducted under programmed loading conditions designed to induce microscopic marking of the crack formation and growth process under varying stress ratio and closure-free crack tip conditions. Control experiments were performed by switching between an air and vacuum environment. In air, varying the stress ratio from 0.74 down to 0.64 retards crack growth by up to a factor of five. This ‘closure-free’ stress ratio history effect totally disappears in vacuum, suggesting a significant environmental influence on stress ratio and its history. Crack-tip stress state appears to moderate environmental action, revealing a potential mechanism sensitive to residual stress. Consequently, crack closure, residual stress and crack front and plane orientation are identified as major load interaction mechanisms whose synergistic action controls fatigue under variable amplitude loading. The study also appears to suggest that as a consequence of the crack seeking the path of least resistance, load-sequence sensitive crack plane and front orientation may only induce retardation effects.
