Academic literature on the topic 'Friendly Society (Sheering, England)'

For this year’s spring meeting, the Society for Acute Medicine took us to Bournemouth on the sunny south coast of England. The Marsham Court Hotel served as an excellent venue for this, the ninth meeting of the society, which ran for two days over the 22nd and 23rd of April. Sunshine, the grand Pier and long stretches of raked beach augmented a relaxed and friendly atmosphere and provided a spectacular backdrop for coffee breaks between sessions.

ObjectivesTo apply and evaluate dementia-friendly community (DFC) principles in prisons.DesignA pilot study and process evaluation using mixed methods, with a 1-year follow-up evaluation period.SettingTwo male prisons: a category C sex offender prison (prison A) and a local prison (prison B).Participants68 participants—50 prisoners, 18 staff.InterventionThe delivery of dementia information sessions, and the formulation and implementation of dementia-friendly prison action plans.MeasuresStudy-specific questionnaires; Alzheimer’s Society DFC criteria; semi-structured interview and focus group schedules.ResultsBoth prisons hosted dementia information sessions which resulted in statistically significant (p>0.05) increases in attendees’ dementia knowledge, sustained across the follow-up period. Only prison A formulated and implemented a dementia action plan, although a prison B prisoner dedicated the prisoner magazine to dementia, post-information session. Prison A participants reported some progress on awareness raising, environmental change and support to prisoners with dementia in maintaining independence. The meeting of other dementia-friendly aims was less apparent. Numbers of older prisoners, and those diagnosed with dementia, appeared to have the greatest impact on engagement with DFC principles, as did the existence of specialist wings for older prisoners or those with additional care needs. Other barriers and facilitators included aspects of the prison institution and environment, staff teams, prisoners, prison culture and external factors.ConclusionsDFC principles appear to be acceptable to prisons with some promising progress and results found. However, a lack of government funding and strategy to focus action around the escalating numbers of older prisoners and those living with dementia appears to contribute to a context where interventions targeted at this highly vulnerable group can be deprioritised. A more robust evaluation of this intervention on a larger scale over a longer period of time would be useful to assess its utility further.

We examine the relationship between age, sickness, and longevity among men who were members of the Hampshire Friendly Society (HFS) in southern England during the late nineteenth and the early twentieth centuries. The HFS insured its members against sickness, death, and old age, keeping detailed records of the claims for sick pay submitted by its members from 1868 onward. From 1892 onward these records included information about the cause of the sickness for which compensation was paid. We can therefore use this information to construct individual “sickness biographies” for men who joined the society during this period. This article uses these sickness histories to address two questions. The first concerns the relationship between the age of the society’s members and the nature of the claims they submitted. We find that both the incidence and the duration of periods of sickness increased with age. Older men experienced longer periods of sickness both because they experienced different types of sickness and because it took them longer to recover from the same illnesses as those suffered by younger men. The second question is whether sickness in early adulthood was associated with increased mortality. We find that repeated bouts of sickness, as revealed by the number of claims made for sick pay, at ages under 50 years were associated with an increased risk of death at ages over 50 years.

Introduction. The International Association of Fire and Rescue Services (hereinafter referred to as CTIF) was founded in August 1900 on the initiative of Count Pavel Kamarovsky, a representative of the Imperial Russian Fire Society. He was elected as the first President of CTIF. 120 years have passed since then, during this period the Association interrupted its activities only during the Second World War. CTIF successfully works, realizing its tasks of developing international cooperation and exchange of experience in various aspects of fire and rescue services, strengthens professional and friendly ties between firefighters and rescuers from different countries of the World on the basis of equal cooperation. Today the Russian National Committee of the International Association of Fire and Rescue Services is studying the activities of the fire and rescue services of the member countries of CTIF to prepare proposals for improving the activities of the fire and rescue services of Russia based on international experience. The article discusses the legal framework, management and financing mechanisms, organizational structure and conditions of service of the fire and rescue services in England. The purpose of the study is to learn international experience, organization and activities of the fire and rescue services in England. Research methods. To obtain the results, general scientific and special methods of scientific knowledge – analysis, generalization, economic analysis, analysis of empirical data, which were based on the general provisions of the theory of analysis and system analysis. Research results. A multifactorial analysis of the activities of the fire and rescue services in England is carried out, taking into account their development in the coming years. Conclusion. The data obtained will make it possible to create a data bank on the activities of the fire and rescue services of the world, as well as to prepare scientifically grounded proposals for the development of fire and rescue services in Russia. Keywords: analysis, statistics, fire, fire and rescue divisions, International Association.

This article raises the problem of the international activities of the Cadet Party from 1906 to 1917. During this period, the Cadets were at the head of the foreign policy activities of the State Duma from the first to the fourth convocations. Firstly, the reason is that the cadets had a developed network of personal and professional contacts with Western politicians and journalists; secondly, they formulated their own vision of foreign policy, and were also ideologically close to the political elite of England and France. The Cadet Party used its international authority in two directions: on the one hand, this increased the party’s authority within the Russian society; on the other hand, Russia was drawing closer to its allies in the Entente. In this rapprochement, it is not so much the geopolitical aspect that is important as the establishment of horizontal ties between the societies of these countries, which allows building long-term friendly relations. This was the main feature of the activities of the Cadets – they did not have government powers, their activities did not lead to the conclusion of agreements, but it influenced public opinion both in Russia and abroad.

Background: Coronavirus disease 2019 (COVID-19) is resurgent in the UK and health and economic costs of the epidemic continue to rise. There is a need to understand the health and economic costs of different courses of action. Methods: We combine modelling, economic analysis and a user-friendly interface to contrast the impact and costs of different testing strategies: two levels of testing within the current test-trace-isolate (TTI) strategy (testing symptomatic people, tracing and isolating everyone) and a strategy where TTI is combined with universal testing (UT; i.e. additional population testing to identify asymptomatic cases). We also model effective coverage of face masks. Results: Increased testing is necessary to suppress the virus after lockdown. Partial reopening accompanied by scaled-up TTI (at 50% test and trace levels), full isolation and moderately effective coverage of masks (30% reduction in overall transmission) can reduce the current resurgence of the virus and protect the economy in the UK. Additional UT from December 2020 reduces the epidemic dramatically by Jan 2021 when combined with enhanced TTI (70% test-trace levels) and full isolation. UT could then be stopped; continued TTI would prevent rapid recurrence. This TTI+UT combination can suppress the virus further to save ~20,000 more lives and avoid ~£90bn economic losses, though costs ~£8bn more to deliver. We assume that all traced and lab-confirmed cases are isolated. The flexible interface we have developed allows exploration of additional scenarios, including different levels of reopening of society after the second lockdown in England as well as different levels of effective mask coverage. Conclusions: Our findings suggest that increased TTI is necessary to suppress the virus and protect the economy after the second lockdown in England. Additional UT from December 2020 reduces the epidemic dramatically by Jan 2021 and could then be stopped, as continued TTI would prevent rapid recurrence.

Rather than a collection of daily introspections, John Winthrop consciously wrote his Journal as a history, with entries that sometimes follow a daily course, and others that omit large periods of time. Some occurrences are more fully treated than others, based on the importance accorded them by Winthrop. As a central character in the political events of the Massachusetts Bay colony, he often offered accounts that either defended or justified his position. Nonetheless, the journal does offer an intriguing view of the society of early Massachusetts. Winthrop's journal often fails to provide a full account of the events it refers to. The fact that this is an abridged edition, representing approximately forty percent of the original journal, undoubtedly magnifies this effect. The reader is aided in contextualizing the material by Dunn and Yeandle's excellent informational footnotes. Most students, unless they possess an intimate knowledge of Puritan New England, would quickly get lost in the plethora of names and places introduced by Winthrop. The notes, however, cannot fix the rather disjointed nature of Winthrop's narrative. The editors' updating of the language has made it fairly user-friendly, but the content tends to jump from one subject to the next, and a number of episodes that Winthrop raises are never satisfactorily concluded. This flaw, of course, belongs to Winthrop, but if one is looking for continuity of narrative, it is difficult to find here.

THE POETRY AND MUSIC OF SCIENCE: Comparing Creativity in Science and Art by Tom McLeish. New York: Oxford University Press, 2022. 414 pages. Paperback; $16.95. ISBN: 9780192845375. *In this tour-de-force book, British physicist Tom McLeish finally comprehensively argues, in one dense volume, what so many scientists have been claiming piecemeal for centuries: that doing science often looks and feels like doing art. That is a broad, amorphous statement, of course, and scientists have not done a very good job of fully understanding this idea or selling it to the rest of the world. This carefully crafted volume must be the most exhaustive work in this area, treating the notion that the creative work of scientists and artists is extraordinarily similar, in that they both fundamentally involve an intimate passion for describing and representing the world around us. *This is not a book about beauty or wonder in science, but rather it examines how scientific ideas and theories come to a scientist's mind and find fruition as publishable science. The entire book juxtaposes literature and art with science and mathematics to help understand the creative process. One important impetus for writing the book, according to McLeish, was recent evidence that smart, capable high schoolers in England were choosing not to go into science because they believed it would not be nearly as fulfilling, creatively, when compared to work in the arts or humanities. McLeish, a Christian, succeeds in this book in showing that not only is creative thinking and experimenting necessary and "part of the chase" in science, but that it is also a natural fulfillment of our creative mandate as human beings made in the image of God. McLeish is also careful to give examples of "more-regular" science, rather than relying solely on the popular accounts of the creativity of exceptional geniuses; he trys to show that all scientists participate in this artistic-like creativity no matter what they are studying. *The first two chapters introduce the concepts of creativity and inspiration in science. McLeish begins an interaction with several important works that he draws on throughout the book: William Beveridge's The Art of Scientific Investigation from 1950, Henry James's The Art of the Novel, and Howard Gardner's 1993 work Creating Minds (one of many surveys of particularly creative individuals). Chapter 3, "Seeing the Unseen," is about visual imagination and its role in theory creation, artistic design, and general problem solving. Visual imagination is seeing things in the mind's eye, but it is obviously linked to actual sight and seeing the world, too. Surveying the history of thought in this area, McLeish ranges from Plato to Gregory of Nyssa, to the thirteenth-century polymath Robert Grosseteste, to the Italian painter Giotto, to Einstein, who said his theory creation and problem solving started with visual images in his mind, which often led to his famous gedanken experiments. Grosseteste is one of the main interlocutors for McLeish throughout the book, being an exemplar of someone having a broad view of thought and creative exploration, not just compartmentalizing a premodern understanding of the physical world from his theological and philosophical commitments. *Chapters 4 through 6 sequentially juxtapose each of the three main areas of scientific work (experiment, theory, and mathematics) with their natural counterpart in literature and music. Experimental science is akin to writing a novel (!?) in that both set up artificial worlds that are tested against the real world and help illuminate the real world. Theoretical science is akin to writing poetry, in that both re-imagine the universe within fixed constraints: poetry within a certain shaping but constraining form, and theoretical visions of what goes on "under" the natural world constrained by a necessary conformity to that world. Chapter 6 compares mathematical creativity with composing and listening to music--the two "wordless" human endeavors in the world of the abstract. *The book is ultimately a treatise on creativity, and as such applies not just to science and art, but to all human endeavors that require creativity. In the final two chapters (7 and 8), McLeish develops what he describes as an "Ur-narrative of creative experience." Starting with a four-step creative process taken from Graham Wallas's 1926 work The Art of Thought, he adds in three more important stages that emerge from his analyses. The seven steps are: vision, desire, industry, constraint, incubation, illumination, and verification. (McLeish has added in desire, industry, and constraint, along with switching Wallas's ideation to vision.) Chapter 7 deals with emotion and drive in scientific creation, and chapter 8 ponders the purpose of human creativity, the telos that ultimately drives scientists and artists to such great lengths in pursuing their creative work. McLeish brings the imago Dei front and center, drawing on the two great hymns in the Book of Job, "Voice from the Whirlwind" (Job 38-42) and "Hymn to Wisdom" (Job 28), as guides to understanding the creative impulse to understand creation. In this he draws on his previous volume with Oxford, Faith and Wisdom in Science. *I believe that listing all the scientific works that McLeish describes in detail with regard to the creative elements behind the works is a good way to convey the magisterial scope of this intellectually rich book. Topics that get 2-10 pages each of description include Feynman's theory of beta decay, McLeish's own considerable contribution to viscous flow in branched polymer melts and his idea of entropically based allostery in biology, Belgian scientist Jan Vermant's work in mesoscale properties of "living matter" (which involves cellular-based material science), "collective phenomenon" and its original invocation by Pierre Weiss in 1907 to explain ferromagnetism, the centuries-long premodern controversy over the nature of sight (intromissive vs. extramissive, etc.), the recent evidence of a star being destroyed by a black hole, Boyle's contributions to the founding of modern experimental science, Alexander von Humboldt's important contributions to the value of a wholistic, multilevel vision of nature and science, Emmy Noether's astonishing discovery of the theoretical origin of conservation laws in physics, the discovery of the all-important fluctuation-dissipation theorem over 30 years (inaugurated by Einstein in 1905, applied to electrical noise by Nyquist in 1928, and fully generalized by Callen and Welton in 1951), the recent development at Caltech of a jet fuel polymer additive that greatly inhibits explosions of jet fuel (motivated in part by the horror of the fuel explosions on 9/11), and finally the full discovery of what causes rainbows by Theodoric in ca. 1310. The descriptions of these historic achievements are each fascinating in their own right and very readable--they alone, for me, would justify an investment in this book. When they are paired with a similar creative work from art, poetry, or fiction, the juxtaposition is extremely fruitful, though the philosophical/psychological analyses get much denser. *Many other discoveries are given much shorter treatment (less than one page), including Andrew Wile's solution to Fermat's Last Theorem, Dirac's mathematical discovery of spin and anti-matter, Poincaré's discovery of a new class of Fuchsian functions, Royer's recent proof of the Gaussian Correlation Inequality in statistics, and Heisenberg on discovering quantum matrix mechanics. The explorations into artistic and literary creativity are typically much shorter, but are nearly as numerous; they include a painting conceptually representing a string-quartet performance by English artist Graeme Willson, Virginia Woolf's To the Lighthouse, Robert Schumann's orchestral work Konzertstück, and Picasso's masterpiece Guernica. *At nearly four hundred pages, this is not light reading and takes some patience and time to get through. It is written at a very high level of sophistication, and therefore one is often "bogged down" trying to make complete sense of what one is reading. (However, if one is not writing a review of the book, one need not spend quite so much time disentangling every dense sentence to get the main gist of the passages.) Also difficult are the many references to previous parts of the book. While these references are entirely appropriate, they are quite demanding of the reader given the sheer number of names and amount of material covered. I had to do quite a bit of flipping back and forth, checking the index to remember exactly what so-and-so said that is now being referenced 100 pages later. In other words, this is a thoroughly academic text. *This is a revised edition of the book, which was first published in 2019. The overwhelming positive response, according to the new preface, prompted the author to immediately answer some of the initial reviews and friendly critiques, which I believe made the book quite a bit better (initially there was not nearly as much about poetry; the comparison of poetry with theoretical science now became a separate chapter, enabling McLeish to more logically and thoroughly cover the territory he had staked out). McLeish sadly died very recently (February 2023) at age 60, while holding the newly created chair in Natural Philosophy at University of York. He was a lay preacher in the Anglican Church and a Fellow of the Royal Society. *Reviewed by Peter Walhout, Chemistry Department, Wheaton College, Wheaton, IL. 60187.

Environments containing significant concentration of NaCl such as salt lakes harbor extremophiles microorganisms which have a great biotechnology interest. To explore the diversity of Bacteria in Chott Tinsilt (Algeria), an isolation program was performed. Water samples were collected from the saltern during the pre-salt harvesting phase. This Chott is high in salt (22.47% (w/v). Seven halophiles Bacteria were selected for further characterization. The isolated strains were able to grow optimally in media with 10–25% (w/v) total salts. Molecular identification of the isolates was performed by sequencing the 16S rRNA gene. It showed that these cultured isolates included members belonging to the Halomonas, Staphylococcus, Salinivibrio, Planococcus and Halobacillus genera with less than 98% of similarity with their closest phylogenetic relative. The halophilic bacterial isolates were also characterized for the production of biosurfactant and industrially important enzymes. Most isolates produced hydrolases and biosurfactants at high salt concentration. In fact, this is the first report on bacterial strains (A4 and B4) which were a good biosurfactant and coagulase producer at 20% and 25% ((w/v)) NaCl. In addition, the biosurfactant produced by the strain B4 at high salinity (25%) was also stable at high temperature (30-100°C) and high alkalinity (pH 11).Key word: Salt Lake, Bacteria, biosurfactant, Chott, halophiles, hydrolases, 16S rRNAINTRODUCTIONSaline lakes cover approximately 10% of the Earth’s surface area. The microbial populations of many hypersaline environments have already been studied in different geographical regions such as Great Salt Lake (USA), Dead Sea (Israel), Wadi Natrun Lake (Egypt), Lake Magadi (Kenya), Soda Lake (Antarctica) and Big Soda Lake and Mono Lake (California). Hypersaline regions differ from each other in terms of geographical location, salt concentration and chemical composition, which determine the nature of inhabitant microorganisms (Gupta et al., 2015). Then low taxonomic diversity is common to all these saline environments (Oren et al., 1993). Halophiles are found in nearly all major microbial clades, including prokaryotic (Bacteria and Archaea) and eukaryotic forms (DasSarma and Arora, 2001). They are classified as slight halophiles when they grow optimally at 0.2–0.85 M (2–5%) NaCl, as moderate halophiles when they grow at 0.85–3.4 M (5–20%) NaCl, and as extreme halophiles when they grow at 3.4–5.1 M (20–30%) NaCl. Hyper saline environments are inhabited by extremely halophilic and halotolerant microorganisms such as Halobacillus sp, Halobacterium sp., Haloarcula sp., Salinibacter ruber , Haloferax sp and Bacillus spp. (Solomon and Viswalingam, 2013). There is a tremendous demand for halophilic bacteria due to their biotechnological importance as sources of halophilic enzymes. Enzymes derived from halophiles are endowed with unique structural features and catalytic power to sustain the metabolic and physiological processes under high salt conditions. Some of these enzymes have been reported to be active and stable under more than one extreme condition (Karan and Khare, 2010). Applications are being considered in a range of industries such as food processing, washing, biosynthetic processes and environmental bioremediation. Halophilic proteases are widely used in the detergent and food industries (DasSarma and Arora, 2001). However, esterases and lipases have also been useful in laundry detergents for the removal of oil stains and are widely used as biocatalysts because of their ability to produce pure compounds. Likewise, amylases are used industrially in the first step of the production of high fructose corn syrup (hydrolysis of corn starch). They are also used in the textile industry in the de-sizing process and added to laundry detergents. Furthermore, for the environmental applications, the use of halophiles for bioremediation and biodegradation of various materials from industrial effluents to soil contaminants and accidental spills are being widely explored. In addition to enzymes, halophilic / halotolerants microorganisms living in saline environments, offer another potential applications in various fields of biotechnology like the production of biosurfactant. Biosurfactants are amphiphilic compounds synthesized from plants and microorganisms. They reduce surface tension and interfacial tension between individual molecules at the surface and interface respectively (Akbari et al., 2018). Comparing to the chemical surfactant, biosurfactant are promising alternative molecules due to their low toxicity, high biodegradability, environmental capability, mild production conditions, lower critical micelle concentration, higher selectivity, availability of resources and ability to function in wide ranges of pH, temperature and salinity (Rocha et al., 1992). They are used in various industries which include pharmaceuticals, petroleum, food, detergents, cosmetics, paints, paper products and water treatment (Akbari et al., 2018). The search for biosurfactants in extremophiles is particularly promising since these biomolecules can adapt and be stable in the harsh environments in which they are to be applied in biotechnology.OBJECTIVESEastern Algeria features numerous ecosystems including hypersaline environments, which are an important source of salt for food. The microbial diversity in Chott Tinsilt, a shallow Salt Lake with more than 200g/L salt concentration and a superficies of 2.154 Ha, has never yet been studied. The purpose of this research was to chemically analyse water samples collected from the Chott, isolate novel extremely or moderate halophilic Bacteria, and examine their phenotypic and phylogenetic characteristics with a view to screening for biosurfactants and enzymes of industrial interest.MATERIALS AND METHODSStudy area: The area is at 5 km of the Commune of Souk-Naâmane and 17 km in the South of the town of Aïn-Melila. This area skirts the trunk road 3 serving Constantine and Batna and the railway Constantine-Biskra. It is part the administrative jurisdiction of the Wilaya of Oum El Bouaghi. The Chott belongs to the wetlands of the High Plains of Constantine with a depth varying rather regularly without never exceeding 0.5 meter. Its length extends on 4 km with a width of 2.5 km (figure 1).Water samples and physico-chemical analysis: In February 2013, water samples were collected from various places at the Chott Tinsilt using Global Positioning System (GPS) coordinates of 35°53’14” N lat. and 06°28’44”E long. Samples were collected randomly in sterile polythene bags and transported immediately to the laboratory for isolation of halophilic microorganisms. All samples were treated within 24 h after collection. Temperature, pH and salinity were measured in situ using a multi-parameter probe (Hanna Instruments, Smithfield, RI, USA). The analytical methods used in this study to measure ions concentration (Ca2+, Mg2+, Fe2+, Na+, K+, Cl−, HCO3−, SO42−) were based on 4500-S-2 F standard methods described elsewhere (Association et al., 1920).Isolation of halophilic bacteria from water sample: The media (M1) used in the present study contain (g/L): 2.0 g of KCl, 100.0/200.0 g of NaCl, 1.0 g of MgSO4.7HO2, 3.0 g of Sodium Citrate, 0.36 g of MnCl2, 10.0 g of yeast extract and 15.0 g agar. The pH was adjusted to 8.0. Different dilutions of water samples were added to the above medium and incubated at 30°C during 2–7 days or more depending on growth. Appearance and growth of halophilic bacteria were monitored regularly. The growth was diluted 10 times and plated on complete medium agar (g/L): glucose 10.0; peptone 5.0; yeast extract 5.0; KH2PO4 5.0; agar 30.0; and NaCl 100.0/200.0. Resultant colonies were purified by repeated streaking on complete media agar. The pure cultures were preserved in 20% glycerol vials and stored at −80°C for long-term preservation.Biochemical characterisation of halophilic bacterial isolates: Bacterial isolates were studied for Gram’s reaction, cell morphology and pigmentation. Enzymatic assays (catalase, oxidase, nitrate reductase and urease), and assays for fermentation of lactose and mannitol were done as described by Smibert (1994).Optimization of growth conditions: Temperature, pH, and salt concentration were optimized for the growth of halophilic bacterial isolates. These growth parameters were studied quantitatively by growing the bacterial isolates in M1 medium with shaking at 200 rpm and measuring the cell density at 600 nm after 8 days of incubation. To study the effect of NaCl on the growth, bacterial isolates were inoculated on M1 medium supplemented with different concentration of NaCl: 1%-35% (w/v). The effect of pH on the growth of halophilic bacterial strains was studied by inoculating isolates on above described growth media containing NaCl and adjusted to acidic pH of 5 and 6 by using 1N HCl and alkaline pH of 8, 9, 10, 11 and 12 using 5N NaOH. The effect of temperature was studied by culturing the bacterial isolates in M1 medium at different temperatures of incubation (4°C–55°C).Screening of halophilic bacteria for hydrolytic enzymes: Hydrolase producing bacteria among the isolates were screened by plate assay on starch, tributyrin, gelatin and DNA agar plates respectively for amylase, lipase, protease and DNAse activities. Amylolytic activity of the cultures was screened on starch nutrient agar plates containing g/L: starch 10.0; peptone 5.0; yeast extract 3.0; agar 30.0; NaCl 100.0/250.0. The pH was 7.0. After incubation at 30 ºC for 7 days, the zone of clearance was determined by flooding the plates with iodine solution. The potential amylase producers were selected based on ratio of zone of clearance diameter to colony diameter. Lipase activity of the cultures was screened on tributyrin nutrient agar plates containing 1% (v/v) of tributyrin. Isolates that showed clear zones of tributyrin hydrolysis were identified as lipase producing bacteria. Proteolytic activity of the isolates was similarly screened on gelatin nutrient agar plates containing 10.0 g/L of gelatin. The isolates showing zones of gelatin clearance upon treatment with acidic mercuric chloride were selected and designated as protease producing bacteria. The presence of DNAse activity on plates was determined on DNAse test agar (BBL) containing 10%-25% (w/v) total salt. After incubation for 7days, the plates were flooded with 1N HCl solution. Clear halos around the colonies indicated DNAse activity (Jeffries et al., 1957).Milk clotting activity (coagulase activity) of the isolates was also determined following the procedure described (Berridge, 1952). Skim milk powder was reconstituted in 10 mM aqueous CaCl2 (pH 6.5) to a final concentration of 0.12 kg/L. Enzyme extracts were added at a rate of 0.1 mL per mL of milk. The coagulation point was determined by manual rotating of the test tube periodically, at short time intervals, and checking for visible clot formation.Screening of halophilic bacteria for biosurfactant production. Oil spread Assay: The Petridis base was filled with 50 mL of distilled water. On the water surface, 20μL of diesel and 10μl of culture were added respectively. The culture was introduced at different spots on the diesel, which is coated on the water surface. The occurrence of a clear zone was an indicator of positive result (Morikawa et al., 2000). The diameter of the oil expelling circles was measured by slide caliber (with a degree of accuracy of 0.02 mm).Surface tension and emulsification index (E24): Isolates were cultivated at 30 °C for 7 days on the enrichment medium containing 10-25% NaCl and diesel oil as the sole carbon source. The medium was centrifuged (7000 rpm for 20 min) and the surface tension of the cell-free culture broth was measured with a TS90000 surface tensiometer (Nima, Coventry, England) as a qualitative indicator of biosurfactant production. The culture broth was collected with a Pasteur pipette to remove the non-emulsified hydrocarbons. The emulsifying capacity was evaluated by an emulsification index (E24). The E24 of culture samples was determined by adding 2 mL of diesel oil to the same amount of culture, mixed for 2 min with a vortex, and allowed to stand for 24 h. E24 index is defined as the percentage of height of emulsified layer (mm) divided by the total height of the liquid column (mm).Biosurfactant stability studies : After growth on diesel oil as sole source of carbone, cultures supernatant obtained after centrifugation at 6,000 rpm for 15 min were considered as the source of crude biosurfactant. Its stability was determined by subjecting the culture supernatant to various temperature ranges (30, 40, 50, 60, 70, 80 and 100 °C) for 30 min then cooled to room temperature. Similarly, the effect of different pH (2–11) on the activity of the biosurfactant was tested. The activity of the biosurfactant was investigated by measuring the emulsification index (El-Sersy, 2012).Molecular identification of potential strains. DNA extraction and PCR amplification of 16S rDNA: Total cellular DNA was extracted from strains and purified as described by Sambrook et al. (1989). DNA was purified using Geneclean® Turbo (Q-BIO gene, Carlsbad, CA, USA) before use as a template in polymerase chain reaction (PCR) amplification. For the 16S rDNA gene sequence, the purified DNA was amplified using a universal primer set, forward primer (27f; 5′-AGA GTT TGA TCM TGG CTC AG) and a reverse primer (1492r; 5′-TAC GGY TAC CTT GTT ACG ACT T) (Lane, 1991). Agarose gel electrophoresis confirmed the amplification product as a 1400-bp DNA fragment.16S rDNA sequencing and Phylogenic analysis: Amplicons generated using primer pair 27f-1492r was sequenced using an automatic sequencer system at Macrogene Company (Seoul, Korea). The sequences were compared with those of the NCBI BLAST GenBank nucleotide sequence databases. Phylogenetic trees were constructed by the neighbor-joining method using MEGA version 5.05 software (Tamura et al., 2011). Bootstrap resembling analysis for 1,000 replicates was performed to estimate the confidence of tree topologies.Nucleotide sequence accession numbers: The nucleotide sequences reported in this work have been deposited in the EMBL Nucleotide Sequence Database. The accession numbers are represented in table 5.Statistics: All experiments were conducted in triplicates. Results were evaluated for statistical significance using ANOVA.RESULTSPhysico-chemical parameters of the collected water samples: The physicochemical properties of the collected water samples are reported in table 1. At the time of sampling, the temperature was 10.6°C and pH 7.89. The salinity of the sample, as determined in situ, was 224.70 g/L (22,47% (w/v)). Chemical analysis of water sample indicated that Na +and Cl- were the most abundant ions (table 1). SO4-2 and Mg+2 was present in much smaller amounts compared to Na +and Cl- concentration. Low levels of calcium, potassium and bicarbonate were also detected, often at less than 1 g/L.Characterization of isolates. Morphological and biochemical characteristic feature of halophilic bacterial isolates: Among 52 strains isolated from water of Chott Tinsilt, seven distinct bacteria (A1, A2, A3, A4, B1, B4 and B5) were chosen for further characterization (table 2). The colour of the isolates varied from beige, pale yellow, yellowish and orange. The bacterial isolates A1, A2, A4, B1 and B5 were rod shaped and gram negative (except B5), whereas A3 and B4 were cocci and gram positive. All strains were oxidase and catalase positive except for B1. Nitrate reductase and urease activities were observed in all the bacterial isolates, except B4. All the bacterial isolates were negative for H2S formation. B5 was the only strain positive for mannitol fermentation (table 2).We isolated halophilic bacteria on growth medium with NaCl supplementation at pH 7 and temperature of 30°C. We studied the effect of NaCl, temperature and pH on the growth of bacterial isolates. All the isolates exhibited growth only in the presence of NaCl indicating that these strains are halophilic. The optimum growth of isolates A3 and B1 was observed in the presence of 10% NaCl, whereas it was 15% NaCl for A1, A2 and B5. A4 and B4 showed optimum growth in the presence of 20% and 25% NaCl respectively. A4, B4 and B5 strains can tolerate up to 35% NaCl.The isolate B1 showed growth in medium supplemented with 10% NaCl and pH range of 7–10. The optimum pH for the growth B1 was 9 and they did not show any detectable growth at or below pH 6 (table 2), which indicates the alkaliphilic nature of B1 isolate. The bacterial isolates A1, A2 and A4 exhibited growth in the range of pH 6–10, while A3 and B4 did not show any growth at pH greater than 8. The optimum pH for growth of all strains (except B1) was pH 7.0 (table 2). These results indicate that A1, A2, A3, A4, B4 and B5 are neutrophilic in nature. All the bacterial isolates exhibited optimal growth at 30°C and no detectable growth at 55°C. Also, detectable growth of isolates A1, A2 and A4 was observed at 4°C. However, none of the bacterial strains could grow below 4°C and above 50°C (table 2).Screening of the halophilic enzymes: To characterize the diversity of halophiles able to produce hydrolytic enzymes among the population of microorganisms inhabiting the hypersaline habitats of East Algeria (Chott Tinsilt), a screening was performed. As described in Materials and Methods, samples were plated on solid media containing 10%-25% (w/v) of total salts and different substrates for the detection of amylase, protease, lipase and DNAse activities. However, coagulase activity was determined in liquid medium using milk as substrate (figure 3). Distributions of hydrolytic activity among the isolates are summarized in table 4.From the seven bacterial isolates, four strains A1, A2, A4 and B5 showed combined hydrolytic activities. They were positive for gelatinase, lipase and coagulase. A3 strain showed gelatinase and lipase activities. DNAse activities were detected with A1, A4, B1 and B5 isolates. B4 presented lipase and coagulase activity. Surprisingly, no amylase activity was detected among all the isolates.Screening for biosurfactant producing isolates: Oil spread assay: The results showed that all the strains could produce notable (>4 cm diameter) oil expelling circles (ranging from 4.11 cm to 4.67 cm). The average diameter for strain B5 was 4.67 cm, significantly (P < 0.05) higher than for the other strains.Surface tension and emulsification index (E24): The assimilation of hydrocarbons as the sole sources of carbon by the isolate strains led to the production of biosurfactants indicated by the emulsification index and the lowering of the surface tension of cell-free supernatant. Based on rapid growth on media containing diesel oil as sole carbon source, the seven isolates were tested for biosurfactant production and emulsification activity. The obtained values of the surface tension measurements as well as the emulsification index (E24) are shown in table 3. The highest reduction of surface tension was achieved with B5 and A3 isolates with values of 25.3 mN m−1 and 28.1 mN m−1 respectively. The emulsifying capacity evaluated by the E24 emulsification index was highest in the culture of isolate B4 (78%), B5 (77%) and A3 (76%) as shown in table 3 and figure 2. These emulsions were stable even after 4 months. The bacteria with emulsification indices higher than 50 % and/or reduction in the surface tension (under 30 mN/m) have been defined as potential biosurfactant producers. Based on surface tension and the E24 index results, isolates B5, B4, A3 and A4 are the best candidates for biosurfactant production. It is important to note that, strains B4 and A4 produce biosurfactant in medium containing respectively 25% and 20% (w/v) NaCl.Stability of biosurfactant activities: The applicability of biosurfactants in several biotechnological fields depends on their stability at different environmental conditions (temperatures, pH and NaCl). For this study, the strain B4 appear very interesting (It can produce biosurfactant at 25 % NaCl) and was choosen for futher analysis for biosurfactant stability. The effects of temperature and pH on the biosurfactant production by the strain B4 are shown in figure 4.biosurfactant in medium containing respectively 25% and 20% (w/v) NaCl.Stability of biosurfactant activities: The applicability of biosurfactants in several biotechnological fields depends on their stability at different environmental conditions (temperatures, pH and NaCl). For this study, the strain B4 appear very interesting (It can produce biosurfactant at 25 % NaCl) and was chosen for further analysis for biosurfactant stability. The effects of temperature and pH on the biosurfactant production by the strain B4 are shown in figure 4. The biosurfactant produced by this strain was shown to be thermostable giving an E-24 Index value greater than 78% (figure 4A). Heating of the biosurfactant to 100 °C caused no significant effect on the biosurfactant performance. Therefore, the surface activity of the crude biosurfactant supernatant remained relatively stable to pH changes between pH 6 and 11. At pH 11, the value of E24 showed almost 76% activity, whereas below pH 6 the activity was decreased up to 40% (figure 4A). The decreases of the emulsification activity by decreasing the pH value from basic to an acidic region; may be due to partial precipitation of the biosurfactant. This result indicated that biosurfactant produced by strain B4 show higher stability at alkaline than in acidic conditions.Molecular identification and phylogenies of potential isolates: To identify halophilic bacterial isolates, the 16S rDNA gene was amplified using gene-specific primers. A PCR product of ≈ 1.3 kb was detected in all the seven isolates. The 16S rDNA amplicons of each bacterial isolate was sequenced on both strands using 27F and 1492R primers. The complete nucleotide sequence of 1336,1374, 1377,1313, 1305,1308 and 1273 bp sequences were obtained from A1, A2, A3, A4, B1, B4 and B5 isolates respectively, and subjected to BLAST analysis. The 16S rDNA sequence analysis showed that the isolated strains belong to the genera Halomonas, Staphylococcus, Salinivibrio, Planococcus and Halobacillus as shown in table 5. The halophilic isolates A2 and A4 showed 97% similarity with the Halomonas variabilis strain GSP3 (accession no. AY505527) and the Halomonas sp. M59 (accession no. AM229319), respectively. As for A1, it showed 96% similarity with the Halomonas venusta strain GSP24 (accession no. AY553074). B1 and B4 showed for their part 96% similarity with the Salinivibrio costicola subsp. alcaliphilus strain 18AG DSM4743 (accession no. NR_042255) and the Planococcus citreus (accession no. JX122551), respectively. The bacterial isolate B5 showed 98% sequence similarity with the Halobacillus trueperi (accession no. HG931926), As for A3, it showed only 95% similarity with the Staphylococcus arlettae (accession no. KR047785). The 16S rDNA nucleotide sequences of all the seven halophilic bacterial strains have been submitted to the NCBI GenBank database under the accession number presented in table 5. The phylogenetic association of the isolates is shown in figure 5.DICUSSIONThe physicochemical properties of the collected water samples indicated that this water was relatively neutral (pH 7.89) similar to the Dead Sea and the Great Salt Lake (USA) and in contrast to the more basic lakes such as Lake Wadi Natrun (Egypt) (pH 11) and El Golea Salt Lake (Algeria) (pH 9). The salinity of the sample was 224.70 g/L (22,47% (w/v). This range of salinity (20-30%) for Chott Tinsilt is comparable to a number of well characterized hypersaline ecosystems including both natural and man-made habitats, such as the Great Salt Lake (USA) and solar salterns of Puerto Rico. Thus, Chott Tinsilt is a hypersaline environment, i.e. environments with salt concentrations well above that of seawater. Chemical analysis of water sample indicated that Na +and Cl- were the most abundant ions, as in most hypersaline ecosystems (with some exceptions such as the Dead Sea). These chemical water characteristics were consistent with the previously reported data in other hypersaline ecosystems (DasSarma and Arora, 2001; Oren, 2002; Hacěne et al., 2004). Among 52 strains isolated from this Chott, seven distinct bacteria (A1, A2, A3, A4, B1, B4 and B5) were chosen for phenotypique, genotypique and phylogenetique characterization.The 16S rDNA sequence analysis showed that the isolated strains belong to the genera Halomonas, Staphylococcus, Salinivibrio, Planococcus and Halobacillus. Genera obtained in the present study are commonly occurring in various saline habitats across the globe. Staphylococci have the ability to grow in a wide range of salt concentrations (Graham and Wilkinson, 1992; Morikawa et al., 2009; Roohi et al., 2014). For example, in Pakistan, Staphylococcus strains were isolated from various salt samples during the study conducted by Roohi et al. (2014) and these results agreed with previous reports. Halomonas, halophilic and/or halotolerant Gram-negative bacteria are typically found in saline environments (Kim et al., 2013). The presence of Planococcus and Halobacillus has been reported in studies about hypersaline lakes; like La Sal del Rey (USA) (Phillips et al., 2012) and Great Salt Lake (Spring et al., 1996), respectively. The Salinivibrio costicola was a representative model for studies on osmoregulatory and other physiological mechanisms of moderately halophilic bacteria (Oren, 2006).However, it is interesting to note that all strains shared less than 98.7% identity (the usual species cut-off proposed by Yarza et al. (2014) with their closest phylogenetic relative, suggesting that they could be considered as new species. Phenotypic, genetic and phylogenetic analyses have been suggested for the complete identification of these strains. Theses bacterial strains were tested for the production of industrially important enzymes (Amylase, protease, lipase, DNAse and coagulase). These isolates are good candidates as sources of novel enzymes with biotechnological potential as they can be used in different industrial processes at high salt concentration (up to 25% NaCl for B4). Prominent amylase, lipase, protease and DNAase activities have been reported from different hypersaline environments across the globe; e.g., Spain (Sánchez‐Porro et al., 2003), Iran (Rohban et al., 2009), Tunisia (Baati et al., 2010) and India (Gupta et al., 2016). However, to the best of our knowledge, the coagulase activity has never been detected in extreme halophilic bacteria. Isolation and characterization of crude enzymes (especially coagulase) to investigate their properties and stability are in progress.The finding of novel enzymes with optimal activities at various ranges of salt concentrations is of great importance. Besides being intrinsically stable and active at high salt concentrations, halophilic and halotolerant enzymes offer great opportunities in biotechnological applications, such as environmental bioremediation (marine, oilfiel) and food processing. The bacterial isolates were also characterized for production of biosurfactants by oil-spread assay, measurement of surface tension and emulsification index (E24). There are few reports on biosurfactant producers in hypersaline environments and in recent years, there has been a greater increase in interest and importance in halophilic bacteria for biomolecules (Donio et al., 2013; Sarafin et al., 2014). Halophiles, which have a unique lipid composition, may have an important role to play as surface-active agents. The archae bacterial ether-linked phytanyl membrane lipid of the extremely halophilic bacteria has been shown to have surfactant properties (Post and Collins, 1982). Yakimov et al. (1995) reported the production of biosurfactant by a halotolerant Bacillus licheniformis strain BAS 50 which was able to produce a lipopeptide surfactant when cultured at salinities up to 13% NaCl. From solar salt, Halomonas sp. BS4 and Kocuria marina BS-15 were found to be able to produce biosurfactant when cultured at salinities of 8% and 10% NaCl respectively (Donio et al., 2013; Sarafin et al., 2014). In the present work, strains B4 and A4 produce biosurfactant in medium containing respectively 25% and 20% NaCl. To our knowledge, this is the first report on biosurfactant production by bacteria under such salt concentration. Biosurfactants have a wide variety of industrial and environmental applications (Akbari et al., 2018) but their applicability depends on their stability at different environmental conditions. The strain B4 which can produce biosurfactant at 25% NaCl showed good stability in alkaline pH and at a temperature range of 30°C-100°C. Due to the enormous utilization of biosurfactant in detergent manufacture the choice of alkaline biosurfactant is researched (Elazzazy et al., 2015). On the other hand, the interesting finding was the thermostability of the produced biosurfactant even after heat treatment (100°C for 30 min) which suggests the use of this biosurfactant in industries where heating is of a paramount importance (Khopade et al., 2012). To date, more attention has been focused on biosurfactant producing bacteria under extreme conditions for industrial and commercial usefulness. In fact, the biosurfactant produce by strain B4 have promising usefulness in pharmaceutical, cosmetics and food industries and for bioremediation in marine environment and Microbial enhanced oil recovery (MEOR) where the salinity, temperature and pH are high.CONCLUSIONThis is the first study on the culturable halophilic bacteria community inhabiting Chott Tinsilt in Eastern Algeria. Different genera of halotolerant bacteria with different phylogeneticaly characteristics have been isolated from this Chott. Culturing of bacteria and their molecular analysis provides an opportunity to have a wide range of cultured microorganisms from extreme habitats like hypersaline environments. Enzymes produced by halophilic bacteria show interesting properties like their ability to remain functional in extreme conditions, such as high temperatures, wide range of pH, and high salt concentrations. These enzymes have great economical potential in industrial, agricultural, chemical, pharmaceutical, and biotechnological applications. Thus, the halophiles isolated from Chott Tinsilt offer an important potential for application in microbial and enzyme biotechnology. In addition, these halo bacterial biosurfactants producers isolated from this Chott will help to develop more valuable eco-friendly products to the pharmacological and food industries and will be usefulness for bioremediation in marine environment and petroleum industry.ACKNOWLEDGMENTSOur thanks to Professor Abdelhamid Zoubir for proofreading the English composition of the present paper.CONFLICT OF INTERESTThe authors declare that they have no conflict of interest.Akbari, S., N.

Abstract In 1801 Sir Frederick Eden estimated that there were 7,200 friendly societies in England and Wales, with about 648,000 members. Two years later poor law returns to Parliament recorded 9,672 societies and more than 704,000 participants. These figures almost certainly underestimate the incidence of clubs and scale of membership. Even so, they suggest that about 40 per cent of the working population in London were members of a friendly society, while at Oldham in Lancashire half the adult male inhabitants belonged to the town’s fifteen clubs, and the position was similar in South Wales. Moreover, unlike most other types of voluntary association, which were almost wholly based in towns, a growing number of box clubs sprang up in the English and Welsh countryside.1 Over the border in Scotland nearly 400 friendly societies had been registered by 1800 (again a serious under-count), major clusters occurring in Edinburgh, Glasgow, and Aberdeen, but clubs also appearing in lesser towns and some Lowland villages. Already in 1779 Glasgow’s eighty or so clubs claimed to represent 12,000 members, and in 1800 the eighteen societies at Dumfries had over 2,000 brethren. In contrast, Ireland returned only seven societies at the end of the century, the incidence probably affected by the political upheavals in the country, as well as by growing economic problems; in 1831 the figure was a more respectable 281 clubs, although getting on for half were concentrated in the Dublin area.

Having established the structures and social and cultural activities of English ethnic associations, Chapter 5 examines in detail the two critical pillars of English ethnic associationalism: charity and mutual aid. It does this through the charity dispensed by St George’s societies, and the collective self-help facilitated in particular by the Sons of England (there are no detailed archives for the OSStG, hence the focus on the SoE). The chapter explores both levels of support and the regulatory framework adopted by the associations to disburse funds. By exploring the aid distributed by St George’s societies, this chapter enables us to examine the level of associational networking between organisations in dispensing charity to all immigrant groups, and the extent to which this gave those organisations a wider civic role. We have located particularly good records for the SoE in Canada and thus explore the workings of this friendly society. Quite unlike the St George’s societies, the SoE built up reserves of members’ funds, which were expended on sickness, unemployment and burial benefits. Ranging across Canada from the Maritimes to British Columbia, and entailing thousands of members in hundreds of lodges, and engaging in the good management of funds and the promulgation of a shared English culture, the Sons add very significantly to our understanding of what it meant to be English in North America.
