Enhancing microplastic removal from natural water using coagulant aids

Microplastic (MP) pollution poses a significant environmental challenge, underscoring the need for improved water treatment methods. This study investigates the effectiveness of coagulation, flocculation, and sedimentation processes for removing microbeads, focusing on key factors that influence removal efficiency. Among the coagulants tested, polyaluminium chloride (PAC) demonstrated superior performance by enhancing the aggregation of microplastics with flocs. Optimal treatment conditions were determined to be 0.4 mmol/L PAC and 3 mg/L polyacrylamide (PAM) at pH 8 (before adding PAC), with rapid stirring at 240 rpm for 1 min, followed by slow stirring at 35 rpm for 13 min, and a sedimentation period of 25 min. Under these conditions, removal efficiencies exceeded 95 % for a range of microbeads (10–1000 μm: Polystyrene (PS), Polypropylene (PP), Polyvinyl chloride (PVC), Polyamide (PA), Polyethylene (PE), and Polyurethane (PU)) from natural water samples. Without PAM, PAC alone achieved a 97 % removal rate for PS microbeads. The addition of PAM maintained high removal efficiency, while aluminium sulphate and ferric chloride were less effective, with removal rates of 67 % and 48 % for PS microbeads, respectively. PAM enhanced MP removal across various coagulants and microbead types, with maximum efficiency observed at PAM concentrations of ≥3 mg/L. The treatment also demonstrated that organic matter in Regent's Park pond water could further improve MP removal. Size significantly impacts removal efficiency: larger microbeads (1 mm to >250 μm) were removed more effectively (95 %) compared to smaller ones (10 to <250 μm), which had a lower removal rate of 49 %. Denser microbeads like PVC (density 1.38 g/cm³) settled more efficiently than lighter microbeads such as PE (density 0.97 g/cm³). These findings suggest a need for advanced technologies to better remove lighter, smaller MPs from water.

Collective Efficacy and Mixed-Tenure Redevelopment: Insights from Toronto’s Regent Park Neighborhood

It is asserted that mixed-tenure public housing redevelopments can improve informal social control in targeted neighborhoods. We investigate this question using a validated measure of collective efficacy from a survey of residents in Toronto’s Regent Park neighborhood. We find that social housing residents report higher perceived levels of collective efficacy than do residents of the market buildings and that households with children report higher perceptions of collective efficacy than do households without children. Our findings provide some support for existing best practices, particularly the provision of amenities for families and the preservation of social ties among social tenants.

Baptists and the Bible in the Nineteenth Century

ABSTRACT This article explores how some Baptists interpreted the Bible in the nineteenth century, focusing particularly on Joseph Angus, Charles Spurgeon, Esther Copley and Marianne Farningham. In light of evidence from Stepney (later known as Regent's Park) College it challenges the suggestion that Baptist reactions to higher criticism were late and uniformly conservative. It also highlights that biblical interpretation in Baptist churches was shaped not only through those educated at the Colleges but also through the writings of women ‘influencers’ such as Copley and Farningham, whose work has been overlooked.

One British Archive: Seeing the Rev. John Clifford Archives and the Gender of Passive Resistance

AbstractThis article discusses the archives of Westbourne Park Baptist Church in London and its world-renowned pastor in the nineteenth and early twentieth centuries, Dr. John Clifford. As leader of the National Passive Resistance League, the fiery Clifford came to be synonymous with the Nonconformist conscience at the height of its political influence in the early twentieth century. The article foregrounds the tension between what I call archival intimacy and archival precarity, while analyzing the power of seeing the diverse photographs in this collection as evidence of the gendered politics of passive resistance in the early twentieth century. Some— though not all—of the collection that I consulted at Westbourne Park Baptist Church in 2016 has now been transferred to the Angus Library, Regent's Park College, Oxford.

Rebuilding Public Housing in Regent Park: The Shifting Dynamics of Financialized Redevelopment Models

This article examines the redevelopment of Toronto’s Regent Park, a neighborhood formerly comprised exclusively of public housing. Since 2006, it has been undergoing a transformation into a mixed income neighborhood. Through interviews and document analysis, the paper traces the complex and changing development agreements as redevelopment progresses, highlighting the state’s entrepreneurial efforts and the dynamic nature of urban planning and policy. We find that practices of financializing public land are highly fluid, and that efforts to derive public value from public housing redevelopment are tied to shifting community expectations regarding the return of benefits to residents.

Stigma consciousness in Toronto’s mixed-tenure Regent Park neighbourhood

The ongoing mixed-tenure redevelopment of Toronto’s Regent Park neighbourhood is a multi-decade effort to rebuild the aging community’s stock of post-war public housing and radically reshape the social composition of the community with the introduction of market owners and renters. This research provides a useful quantitative complement to the now extensive body of qualitative research concerning the neighbourhood’s redevelopment, specifically investigating perceptions of stigma among both public housing and market residents using Pinel’s Stigma Consciousness Questionnaire. We find that respondents of all tenures report relatively low levels of stigma consciousness. Unexpectedly, the largest observed difference between discrete tenure groups was between market owners and renters within the market units. Additionally, we find that non-native speakers of English report lower levels of stigma consciousness while the largest source of variation, by a wide margin, is between individuals.

“Here They Are in Flesh and Feather”: Walter Rothschild's “Private Zoo” and the Preparation and Taxonomic Study of Cassowaries

Large, black, flightless birds with unpredictable tempers and colourful heads and necks, cassowaries have enthralled European audiences for centuries, but perhaps no one more so than private collector and zoologist Lionel Walter Rothschild (1868-1937). Throughout the late 19th and early 20th centuries, Rothschild acquired hundreds of living cassowaries which were kept in his private zoological collection. This paper explores the nature of Rothschild's private zoo and how the collection of living cassowaries was used to support his zoological activities. Spread across three sites-the family estate at Tring Park, the zoological gardens in Regent's Park, and the business premises of Cambridge-based taxidermist Frederick Doggett-it will examine how Rothschild used the living birds kept in his private zoo to devise and inform a process for the preparation and display of cassowary specimens in museum galleries. It will show how he recruited specialist artists and taxidermists to perfect the art, and the significant financial investment this entailed. This is followed by exploration of how Rothschild's access to and observations of living birds informed his taxonomic work and, in particular, the identification of species and subspecies. The argument is made that Rothschild's private zoo and access to living cassowaries enabled his dedication to the study of the genus and ultimately underpinned his reputation as a world authority on cassowaries in the early 20th century.

New Urbanism as a Remedy for Modernist Urban Renewal

Over the past twenty years, Regent Park, a neighborhood in Toronto, Ontario, has undergone the application of the Canadian planning profession’s leading practices and theories throughout its redevelopment. The project has firmly adopted the New Urbanist planning principles that have resulted in a starkly different neighborhood than what had existed before. As a result, it provides an excellent case study for how social housing has been shaped by the Modernist and New Urbanist planning movements. This paper argues that New Urbanism has emerged out of the need to solve the problems in social housing created by Modernist urban renewal. This will be supported by a brief history of Modernism and urban renewal’s roots, its effects on Regent Park, the neoliberal transition in social housing in Canada, and the New Urbanist application to Regent Park.

Photodegradation of free estrogens driven by UV light: Effects of operation mode and water matrix

Estrogens are endocrine disrupting chemicals that have been frequently detected in diverse water matrices (e.g. surface water, wastewater and drinking water) and caused a series of health risks. This study was aimed at investigating the photochemical degradation of free estrogens estrone (E1), 17β-estradiol (E2), estriol (E3), and 17α-ethyl estradiol (EE2) upon the monochromatic irradiation (253.7 nm). Concerning the practical installation of photolysis treatment, exposing the impacts of photoreactor operation mode (stationary or up-flow) and the water matrix (ultrapure water or natural surface water) on the photolytic behaviour of estrogens was of high importance. The pseudo-first-order rate constants showed that E1 was the most susceptible to UV radiation among chosen estrogens due to its high molar absorption coefficient of 402.4 M−1 cm−1 and quantum yield of 0.065 mol E−1 at λ = 253.7 nm. Moreover, the up-flow mode and the surface water matrix collected from a lake in Regent's Park (London) were found to favour the photodegradation of estrogens due to the introduction of more dissolved oxygens and promotion of reactive oxygen species (ROS) formation. These findings may shed light on the photochemical behaviour of estrogens in some specific scenarios.

Diasporic Archives and Hauntological Accretions

Centering on two recent participatory archive projects, Jacqueline Hoàng Nguyễn’s The Making of An Archive (2014-present), and Regent Park Film Festival’s Home Made Visible (2017-2019), this essay examines how diasporic archives “densify” authoritative records, and allow us to think generatively about archival movements and accretions. Both projects gathered and digitised archives from members of diasporic and racialised communities. Through public calls and workshops soliciting amateur archivists’ personal and familial still and moving image troves, these projects prioritised excavating and inscribing quotidian and ephemeral records as a response to Canadian multiculturalism’s imposed silences. The essay approaches diaspora – and diasporic archives – not (just) through rubrics of loss and obsolescence, but through the concept of hauntological thickening, arguing that these two projects intervene on authoritative and singular archival narratives by densifying the latter with occluded histories, affects, and textural traces of transfer. It also examines how quotidian visual records offer hauntological refractions of official narratives, and become vehicles for imbrications of personal, familial, and national histories and discourses. Finally, the essay concludes with an exploration of how the archives engage audiences through affective and sensorial registers.

What determines a boundary for navigating a complex street network: evidence from London taxi drivers

AbstractSpatial boundaries play an important role in defining spaces, structuring memory and supporting planning during navigation. Recent models of hierarchical route planning use boundaries to plan efficiently first across regions and then within regions. However, it remains unclear which structures (e.g. parks, rivers, major streets, etc.) will form salient boundaries in real-world cities. This study tested licensed London taxi drivers, who are unique in their ability to navigate London flexibly without physical navigation aids. They were asked to indicate streets they considered as boundaries for London districts or dividing areas. It was found that agreement on boundary streets varied considerably, from some boundaries providing almost no consensus to some boundaries consistently noted as boundaries. Examining the properties of the streets revealed that a key factor in the consistent boundaries was the near rectilinear nature of the designated region (e.g. Mayfair and Soho) and the distinctiveness of parks (e.g. Regent's Park). Surprisingly, the River Thames was not consistently considered as a boundary. These findings provide insight into types of environmental features that lead to the perception of explicit boundaries in large-scale urban space. Because route planning models assume that boundaries are used to segregate the space for efficient planning, these results help make predictions of the likely planning demands of different routes in such complex large-scale street networks. Such predictions could be used to highlight information used for navigation guidance applications to enable more efficient hierarchical planning and learning of large-scale environments.

A simple ZVI-Fenton pre-oxidation using steel-nails for NOM degradation in water treatment

The feasibility of a heterogeneous Fenton Process (ZVI/H2O2) using commercial low-carbon-steel nails as the Zero-Valent Iron (ZVI) source was evaluated for the first time for the removal of natural organic matter (NOM) from natural surface waters with distinct physico-chemical characteristics. The synergistic effect of ZVI nails and H2O2 on the process was confirmed. Results showed similar removal efficiencies of NOM in water samples from Thames river and Regent's Park lake (both in London, UK) (under initial pH 3.5 and 100% excess of H2O2 dosage), reaching dissolved organic carbon (DOC) removals of 61.6% ± 3.0 and 59.6% ± 4.7, and UV254 removals of 79.9% ± 0.6 and 77.3 ± 6.2, respectively with 60 min of batch reaction time. ZVI nail surface characterization by scanning electron microscopy (SEM), X-ray energy-dispersive spectroscopy (EDS), and X-ray photoemission spectroscopy (XPS) revealed the formation of a passivating oxide-hydroxide layer on the nail during the reaction, which reduces its surface activity with 20% in continuous use. Results indicate that ZVI/H2O2 process using commercial iron nails is a promising pre-oxidation step for drinking water treatment. The low cost of commercial nails together with the facility of separating them from the water are the main advantages for the application of this process in remote regions with limitations in infrastructure and/or finance.

The Baptist Quarterly: The First Decade (1922–1931)

ABSTRACT The Baptist Quarterly began in 1922 as a successor to the Transactions of the Baptist Historical Society. In its first decade, the Quarterly was greatly indebted to the Honorary Secretary of the Baptist Historical Society, W.T. Whitley, and the President of the Society and Principal of Regent's Park College, Wheeler Robinson. This article considers how the Quarterly, from 1922–1931, sought to foster historical investigation and also, as Robinson put it, to ‘express contemporary Baptist aims and interests' on ‘a broader basis'. After ten years of the Quarterly, Robinson argued that it had made ‘a wider appeal by including matters of contemporary as well as of antiquarian interest’. In examining in detail that period, this study proposes that five main areas were of greatest significance: contemporary church life and mission; Baptist history in particular places in Britain; international experience; theological and biblical issues; and the more general historical area.

A Short History of the Angus Library and Archives, Regent’s Park College, Oxford

ABSTRACT This article surveys the history of the Angus Library and Archives at Regent's Park College, Oxford, from its foundation to the present day, setting it within four historical periods. The article includes the history of notable accessions of books and manuscripts to the Angus, its character, its close association with the Baptist Historical Society, and its shaping over the years by a number of key persons. It traces a development from the personal collection of the first Principal to its present status as the central archive for Baptist studies in the UK, through merger with the library of the Baptist Union of Great Britain – including the former library of the Baptist Historical Society – and the archives of the Baptist Missionary Society. Its function as a place for continuous deposit of Baptist Union documents, its holdings that relate to Baptists worldwide, and its recent activity in educational ‘outreach’ are also related.

“On Deposit”: animal acquisition at the Zoological Society of London, 1870–1910 (Patron's review)

When the zoological gardens in Regent's Park opened to the public in 1847, they immediately became very popular, providing a source of both entertainment and instruction for visitors and a vital stream of revenue for the Zoological Society of London. However, the ongoing popularity of the gardens was endangered by the consistently high mortality rates which afflicted the Society's animals throughout the course of the nineteenth and early-twentieth centuries. This paper examines how the Society's efforts to combat this challenge led them to foster and sustain relationships which centred on the act of animal “deposit”. Often a temporary arrangement, somewhat like a loan, depositing involved a range of individuals involved in the animal trade, including commercial animal dealers and the naturalist Lionel Walter Rothschild. Through the system of depositing, the Zoological Society became the custodians of a wide range of animals which they could exhibit. However, their lack of ownership of these animals, combined with a lack of knowledge about how to care for them, ultimately constrained the Society's management of them and impeded its longer-term goals of reducing both animal mortality and the impact of high mortality rates on the menagerie's ability to attract visitors and sustain its economy.

Teddy, The Little Refugee Mouse by Dorothy Burroughes, and: The Magic Herb by Dorothy Burroughes

Reviewed by: Teddy, The Little Refugee Mouse by Dorothy Burroughes, and: The Magic Herb by Dorothy Burroughes Jan Susina (bio) Teddy, The Little Refugee Mouse. By Dorothy Burroughes, edited by Jack Zipes. Little Mole and Honey Bear, 2021. The Magic Herb. By Dorothy Burroughes, edited by Jack Zipes. Little Mole and Honey Bear, 2021. The most recent reprints in Jack Zipes's Fabulous Excavated Tales series are two books written and illustrated by Dorothy Burroughes. Popular during the 1930s and 1940s, Burroughes is a British children's author who is rarely mentioned in the histories of children's literature but is still held in high regard as a print maker and poster artist. Trained at the Slade School of Fine Art, Burroughes's first major success as a commercial artist was designing posters in 1920 for the London Underground that encouraged visitors to the London Zoo in Regent's Park. Drawn in the style of Japanese woodcuts, her image of Langur monkeys became popular with the public. Her second zoo poster, known as "the monkey poster," became the most requested poster in the history of the London Underground and is reprinted in both volumes along with her striking print of "The Black Panther." In the 1930s and 1940s, Burroughes was considered one of the leading British animal artists, along with Harry Rountree and Cecil Aldin. Many of her twenty children's books, like her better-known posters and prints, focus on animals and animal rights. Burroughes established her reputation as an animal artist with her prints and posters often featuring animals that she sketched at the Regent's Park Zoo and was awarded a Zoological Society Fellowship for her animal artwork. Yet she expressed mixed feelings about zoos and restricting animals in cages. In addition to illustrating informational books on animals such as Queer Beasts at the Zoo (1927) and Queer Birds at the Zoo (1927), Burroughes also wrote children's stories featuring anthropomorphized creatures that address social issues and emphasize the need to treat animals with respect and kindness. While Burroughes uses watercolor illustrations interspersed with linocuts in her children's books, her stories are longer and more complicated than those by Beatrix Potter and are intended for older readers. Her chummy and social world of animals more closely resembles that of Kenneth Grahame in [End Page 445] The Wind in the Willows, without the humorous escapades of Mr. Toad that A.A. Milne admired. The Magic Herb shows a bit of Lewis Carroll influence. Three badgers go on a quest for the Magic Herb to aid their seriously ill baby brother. To obtain the mysterious plant, they must journey to the Magic Isle where the white plant is guarded by the Dodo and the Unicorn. Burroughes draws the Dodo so he resembles John Tenniel's illustration of the Dodo in Alice's Adventures in Wonderland. The Dodo, who initially appears rather fierce, is just "a little embittered by being misunderstood" (19). He is moved by the unselfish nature of the badgers' quest. As the Unicorn explains to the badgers, he and the Dodo are tasked with the responsibility of preventing the life-restoring plant from falling into the wrong hands, such as "pompous scientists and people who-want-towrite-to-the-papers" about discovery of this rare species. The selfless nature of the badgers' quest is reminiscence of Gluck's journey in John Ruskin's The King of the Golden River. The badgers succeed on their impossible journey, liberate the Dodo and the Unicorn from their long-term duties as protectors of the Magic Herb, and restore their younger brother to health, all a result of their selflessness. Teddy, The Little Refugee Mouse is an updated version of Aesop's "Country Mouse and City Mouse." Teddy is an elegant mouse who wears a smart gray coat with clean white collars. He accompanies his human family when they vacate London for the country for the duration of the War. Burroughes uses animal figures to comfort younger readers who were moved from the cities to escape Nazi bombing during World War II. Teddy is befriended by the Brown Mouse family who introduce him to the rural world of cows, pigs...
