Tea and mainly green tea as a rich source of antioxidants has been widely known for some time.  The antioxidant capacity of tea including green tea is mainly due to its catechins content.  The objective of this study was to determine the relationship between the ORAC value and the catechins content. Regular and decaffeinated commercial green tea bags commonly consumed in the United Kingdom (UK) have been examined using Reversed-Phase High-pressure Liquid Chromatography (RP-HPLC). Teabags were purchased from different local supermarkets in the UK and extracted with natural mineral water at temperature 100°C for 9 minutes at the pre-adjusted pH 4. The level of four catechins (Epi-structured) for the thirteen types of green tea were separated and determined by HPLC analysis, i.e. ()-epigallocatechin (EGC), ()-epicatechin (EC), ()-epigallocatechin-3-gallate (EGCG) and ()-epicatechin gallate (ECG). The standard graphs were validated using certified reference catechins supplied by the Laboratory of the Government Chemist (LGC). The levels of total catechins and oxygen radical absorbance capacity (ORAC) values varied from 34.61to 204.55 mg/g, 830.19- 4197.81 Trolox equivalents/g tea bags for thirteen types of green teas respectively. It was clear from the results of this study that there was a significant linear and positive correlation (r = 0.951, df = 12, p < 0.05) is found to exist between the total catechins contents and ORAC values. It can be concluded that the results of catechins measurements coupled to this; the well-known ORAC assay was successfully modified to measure the antioxidant capacity of the green tea extracts throughout this study. Furthermore, the higher the level of catechins the higher is the antioxidant capacity of the tea. This may stimulus consumers in selecting the type of tea and tea brewing times, exhibiting more health benefits. Nevertheless, the differences between the studied brands are owing to shelf life, production and storage conditions.

This paper examines how the British government has used statistics about COVID-19 for political ends. A distinction is made between precise and round numbers. Historically, using round numbers to estimate the spread of disease gave way in the 19th century to the sort precise, but not necessarily accurate, statistics that are now being used to record COVID-19. However, round numbers have continued to exert rhetorical, ‘semi-magical’ power by simultaneously conveying both quantity and quality. This is demonstrated in examples from the British government’s claims about COVID-19. The paper illustrates how senior members of the UK government use ‘good’ round numbers to frame their COVID-19 goals and to announce apparent achievements. These round numbers can provide political incentives to manipulate the production of precise number; again examples from the UK government are given.

Objective: The mainstay of palatal repair in the United Kingdom is the intravelar veloplasty (IVVP). It is not always possible to align the oral mucosa in the midline to achieve tension-free repair. The addition of lateral relieving incisions may aid transposition of the oral mucosa to allow closure. The aim of this study was to explore cleft features that may predispose to a requirement for relieving incisions in order to allow palate closure. Design: We performed a national multiinstitutional retrospective study using data from the UK Cleft Collective cohort study. Patients: The study sample consisted of 474 patients who had undergone IVVP at the time of palatal closure across all 16 of the UK cleft units. Results: We found strong evidence for the requirement for relieving incisions in patients with an increased degree of clefting per the Veau classification ( P < .001), increasing palatal soft-edge width ( P < .001) and moderate evidence of an associated use in patients with Pierre Robin sequence ( P = .015). Insufficient data were available to explore the relationship between intertuberosity distance and the presence of fistula formation with the use of relieving incisions. Conclusions: The results of this study identify cleft features that increase the likelihood for requiring lateral relieving incisions to allow palatal closure. The degree to which the addition of relieving incisions to IVVP affects maxillary growth and speech outcomes is unknown. Further study is required to answer this important question.

The past decade has seen the growth of a considerable literature on the link between government popularity, as reflected by the proportion of the public indicating their intention to vote for the government in opinion polls, and the state of the economy, as represented by certain key variables. The work began in the early 1970s with articles by Goodhart and Bhansali, Mueller, and Kramer. It continued through the decade; some of the more recent contributions can be found in a set of readings edited by Hibbs and Fassbender. However, despite the amount and quality of this work, problems remain. Principal amongst these, as Chrystal and Alt have pointed out, is the inability to estimate a relationship which exhibits any degree of stability either over time or between researchers. Nearly all the studies have been successful in finding a significant relationship for specific time periods, but when these are extended, or when the function is used to forecast outside the original estimation period, the relationship appears to break down.

Across the European Union, national governments are re-assessing the institutional mechanisms through which pension provision is delivered. This articles sets the debate within the wider context of the ‘pillared’ structural analysis often adopted by international institutions when discussing pensions reform. It then sets out a detailed discussion of developments in the UK, arguing that the UK is moving towards a model of reform akin to that promoted by the World Bank – referred to here as ‘pillared-privatisation’. The themes of this model indicate more means-testing, greater private provision, and a shift of the burden of risk from the government to individuals. An assessment is then made of the implications of UK developments for other EU countries. It is suggested that while there are strong reasons to think that other countries will not travel as far down the road of ‘pillared-privatisation’ as the UK, this should not be taken as a ‘given’.

Face to face dental care in the UK was largely suspended from March until June and beyond is very limited still in many cases. Both NHS and Private dental services in the four nations of the United Kingdom aligned with the government in lockdown and dental emergencies could be accessed face to face in specific urgent centres only (UDC’s). Return to dental practice has been challenging for the profession with a lack of clarity from regulators and a gulf between financial support of private practice (almost none) and National Health practice (at 100% of their contact value pre-COVID). Dramatic changes to the provision of dental care are likely to persist and the COVID crisis may precipitate significant change to both private and NHS dental services.

This chapter assesses the history of the relationship between public and private sectors and the extent to which the political and regulatory environment of governments and institutions such as the European Union (EU) can help or hinder the efforts of public bodies in seeking to deliver services that determine the health and quality of life for communities. The relationship of public and private sectors in the United Kingdom (UK) and the commissioning, procurement, and development of public–private partnerships is driven by the prevailing political and economic environment. However, rigorous academic research on the benefits of partnering to organisations, societies and between countries is limited. Evidence is needed to fill the policy vacuum. A bolder approach is necessary to work with public and private sectors to develop and implement successful partnering alternatives to the outsourcing of public services. The growing catalogue of outsourcing failures in construction, probation, rail franchising, health, and social care is creating an appetite for change, and the exit of the UK from the EU provides the opportunity.

This chapter discusses the reception of Community (now EU law) in the UK courts, and in particular how UK courts reconciled the doctrine of supremacy with the doctrine of parliamentary sovereignty. The chapter will examine three ways in which the UK courts have attempted to reconcile these competing doctrines: by constructing national law in light of EU law; by disapplying conflicting national law; and by reasserting national sovereignty and threatening not to apply EU law automatically. Finally, the chapter will briefly re-visit the case of Miller in order to evaluate that case in light of earlier cases on the relationship between UK and EU law.

The central government in the UK is determined to employ new surveillance technology to combat the threat of terrorist activities. This chapter contributes to the important debate on the relationship between citizens and the government, by discussing not whether electronic surveillance should be used, but rather, when it is acceptable to the populace. From our analysis, we conclude that a reconciliation of state-interest and self-interest is critical for the success of e-governance; as such, electronic surveillance’s mission has to be about serving the law-abiding majority and their needs, and its scope and benefits must be clearly understood by the visionaries, implementers and the citizenry.

This article analyses the relationship between a Scottish manufacturing company and the accountancy firm which provided it with professional services across its existence (1894–1967). It examines the professional roles fulfilled by the accountants, the work done and the fee income derived from it, in the context of the company’s history. It emphasises the importance of the services provided by accountancy firms for unlisted companies in understanding the development of professional accountancy in the United Kingdom. The material presented is used to test three different explanations of the UK accountancy profession’s rise which relate to the auditing function and has implications for historical methodology and epistemologies. The explanations explored may be categorised as economic rationalist, Foucauldian and jurisdictional points of view.

2020 had been marked as a significant year for the UK with its departure from the European Union. The coronavirus pandemic quickly became the most important issue facing the Government under a third Prime Minister since the 2016 referendum. From the start, problems have dogged this Government in meeting the monumental challenges posed by Covid-19. The UK approached the work implications of this pandemic in some distinct ways, as compared to European Union Member States. This piece is longer than other country reports in this volume as a result of critically engaging with these differences.
