description: Decreasing volumes and increasing input costs continued to plague the cotton warehousing industry during fiscal 1971-72. Total storage cost increased almost 60 percent over comparable cost for 1970-71. Total fixed cost and personnel expenses accounted for 75 percent of the total storage cost. These findings are based on an analysis of accounting and operational data obtained from warehouse and compress facilities. Increases occurred in the cost of all other services with the exception of the breakout function. Sample data were also used to develop projected storing and handling costs for fiscal 1973-74. These costs reflect projected changes in volumes handled and stored and expected changes in cost levels. Costs so developed were based on projected production of 11.4 and 13.0 million bales, beginning inventory in public storage of 2.9 million bales, and disappearance of 11.6 million bales.

description: We report the synthesis of graphene oxide/nickel oxide/β-cyclodextrin (GO/NiO/β-CD) nanocomposite and the efficiency of the nanocomposite in decolourising two different dyes, methylene blue (MB) and methyl violet (MV). GO was prepared by modified Hummer’s method while hydrothermal method was used for the preparation of GO/NiO/β-CD. The as-synthesised nanocomposites were characterised by X-ray diffraction (XRD), and Fourier transform infrared (FTIR) spectroscopy, Raman spectroscopy and high resolution transmission electron microscopy (HR-TEM). Photocatalytic degradation was carried out under solar light by monitoring the concentration of MB and MV dyes. Degradation reaction followed Langmuir-Hinshelwood pseudo first-order kinetic model. The apparent reaction rate constant (k) for MB increased as compared to MV under solar light irradiation. The MB showed better photocatalytic degradation efficiency by GO/NiO/β-CD composites. GO/NiO/β-CD nanocomposite has been very favourable for photocatalytic application.

description: Recently, there has been much attention devoted to resolving the quantum corrections to the Bekenstein-Hawking (black hole) entropy, which relates the entropy to the cross-sectional area of the black hole horizon. Using generalized uncertainty principle (GUP), corrections to the geometric entropy and thermodynamics of black hole will be introduced. The impact of GUP on the entropy near the horizon of three types of black holes; Schwarzschild, Garfinkle-Horowitz-Strominger and Reissner-Nordström is determined. It is found that the logarithmic divergence in the entropy-area relation turns to be positive. The entropy $S$, which is assumed to be related to horizon's two-dimensional area, gets an additional terms, for instance $2\, \sqrtπ\, α\, \sqrt{S}$, where $α$ is the GUP parameter.

Catalysis-dependent stabilization of Bre1 fine-tunes histone H2B ubiquitylation to regulate gene transcription

description: Monoubiquitylation of histone H2B on Lys123 (H2BK123ub1) plays a multifaceted role in diverse DNA-templated processes, yet the mechanistic details by which this modification is regulated are not fully elucidated. Here we show in yeast that H2BK123ub1 is regulated in part through the protein stability of the E3 ubiquitin ligase Bre1. We found that Bre1 stability is controlled by the Rtf1 subunit of the polymerase-associated factor (PAF) complex and through the ability of Bre1 to catalyze H2BK123ub1. Using a domain in Rtf1 that stabilizes Bre1, we show that inappropriate Bre1 levels lead to defects in gene regulation. Collectively, these data uncover a novel quality control mechanism used by the cell to maintain proper Bre1 and H2BK123ub1 levels, thereby ensuring proper control of gene expression.

description: We give a brief review of the AdS/CFT correspondence, which posits the equivalence between a certain gravitational theory and a lower-dimensional non-gravitational one. This remarkable duality, formulated in 1997, has sparked a vigorous research program which has gained in breadth over the years, with applications to many aspects of theoretical (and even experimental) physics, not least to general relativity and quantum gravity. To put the AdS/CFT correspondence in historical context, we start by reviewing the relevant aspects of string theory (of which no prior knowledge is assumed). We then develop the statement of the correspondence, and explain how the two sides of the duality map into each other. Finally, we discuss the implications and applications of the correspondence, and indicate some of the current trends in this subject. The presentation attempts to convey the main concepts in a simple and self-contained manner, relegating supplementary remarks to footnotes.

description: The mammalian circadian clock is based on a transcription–translation feedback loop (TTFL) in which CLOCK and BMAL1 proteins act as transcriptional activators of Cryptochrome and Period genes, which encode proteins that repress CLOCK–BMAL1 with a periodicity of ∼24 h. In this model, the mechanistic roles of CRY and PER are unclear. Here, we used a controlled targeting system to introduce CRY1 or PER2 into the nuclei of mouse cells with defined circadian genotypes to characterize the functions of CRY and PER. Our data show that CRY is the primary repressor in the TTFL: It binds to CLOCK–BMAL1 at the promoter and inhibits CLOCK–BMAL1-dependent transcription without dissociating the complex (“blocking”-type repression). PER alone has no effect on CLOCK–BMAL1-activated transcription. However, in the presence of CRY, nuclear entry of PER inhibits transcription by displacing CLOCK–BMAL1 from the promoter (“displacement”-type repression). In light of these findings, we propose a new model for the mammalian circadian clock in which the negative arm of the TTFL proceeds by two different mechanisms during the circadian cycle.

description: The three EglN prolyl hydroxylases (EglN1, EglN2, and EglN3) regulate the stability of the HIF transcription factor. We recently showed that loss of EglN2, however, also leads to down-regulation of Cyclin D1 and decreased cell proliferation in a HIF-independent manner. Here we report that EglN2 can hydroxylate FOXO3a on two specific prolyl residues in vitro and in vivo. Hydroxylation of these sites prevents the binding of USP9x deubiquitinase, thereby promoting the proteasomal degradation of FOXO3a. FOXO transcription factors can repress Cyclin D1 transcription. Failure to hydroxylate FOXO3a promotes its accumulation in cells, which in turn suppresses Cyclin D1 expression. These findings provide new insights into post-transcriptional control of FOXO3a and provide a new avenue for pharmacologically altering Cyclin D1 activity.

description: Recent work has shown the existence of a relativistic effect present in a single component non-equilibrium fluid, corresponding to a heat flux due to an electric field. The treatment in that work was limited to a four-dimensional Minkowksi space-time in which the Boltzmann equation was treated in a special relativistic approach. The more complete framework of general relativity can be introduced to kinetic theory in order to describe transport processes associated to electromagnetic fields. In this context the original Kaluza's formalism is a promising approach. The present work contains a kinetic theory basis for Kaluza's magnetohydrodynamics and gives a novel description for the establishment of thermodynamic forces beyond the special relativistic description.

description: In this work, carbon hybridised sepiolite nanofibers (C/Sep) were successfully prepared via hydrothermal and post-calcination processes. The synthesised nanocomposite was then modified with 2-[(5-bromo-2-pyridyl)azo)-5-(diethl-amino) phenol (PADAP) as a chelating agent. Fourier transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FE-SEM), energy-dispersive X-ray (EDX) spectroscopy and X-ray diffraction (XRD) analyses were employed for characterisation of the sorbent (C/Sep/PADAP). Application of the sorbent was studied for separation/preconcentration of Pb(II) prior to the determination by flame atomic absorption spectrometry (FAAS). Experimental factors including solution pH, sorption and desorption time, eluent type and concentration, sorbent dosage and sample volume were evaluated. A preconcentration factor of 125 with a linear range of 7.0–1100 µg L−1 was obtained for Pb(II) detection using this method. Beside, the detection limit (3σ) of the extraction procedure for Pb(II) was 1.1 µg L−1. The applicability of the proposed assay for determination of Pb(II) in actual water samples was also investigated.

description: Polycomb-repressive complex 2 (PRC2) catalyzes the methylation of histone H3 Lys27 (H3K27) and functions as a critical epigenetic regulator of both stem cell pluripotency and somatic differentiation, but its role in male germ cell development is unknown. Using conditional mutagenesis to remove the core PRC2 subunits EED and SUZ12 during male germ cell development, we identified a requirement for PRC2 in both mitotic and meiotic germ cells. We observed a paucity of mutant spermatogonial stem cells (SSCs), which appears independent of repression of the known cell cycle inhibitors Ink4a/Ink4b/Arf. Moreover, mutant spermatocytes exhibited ectopic expression of somatic lamins and an abnormal distribution of SUN1 proteins on the nuclear envelope. These defects were coincident with abnormal chromosome dynamics, affecting homologous chromosome pairing and synapsis. We observed acquisition of H3K27me3 on stage-specific genes during meiotic progression, indicating a requirement for PRC2 in regulating the meiotic transcriptional program. Together, these data demonstrate that transcriptional repression of soma-specific genes by PRC2 facilitates homeostasis and differentiation during mammalian spermatogenesis.

description: Industrial effluents contain many toxic heavy metal ions and they are the main source for water pollution. Different methods are adopted for the purification of infected water. Among the diverse techniques, ion exchange method using conducting polymer based ion exchange material has several advantages over than other traditional methods like adsorption. In the present work, polyaniline/Ti(IV) iodosulphosalicylate (PANI/Ti(IV) ISS) a conducting polymer based ion exchange material was synthesised by sol–gel method via the mixing of inorganic precipitate of Titanium(IV) iodosulphosalicylate (Ti(IV) ISS) into the matrix of organic conducting polymer polyaniline (PANI). The PANI/Ti(IV) ISS conducting polymer based ion exchange material was well characterised using techniques such as Fourier Transform Infrared Spectroscopy (FT-IR), X-ray diffraction studies (XRD), scanning electron microscopy (SEM), energy dispersive X-Ray (EDAX), transmission electron microscopy (TEM) and thermal (TGA/DTG) analysis. The ion exchange capacity, elution behaviour, elution time and pH titration studies were also investigated. Furthermore a.c. electrical conductivity studies and impedance spectrum of this material also carried out. Some binary separations of heavy metal ions were achieved by the column packed by PANI/Ti(IV) ISS conducting polymer based ion exchange material. PANI/Ti(IV) ISS conducting polymer based ion exchange material showed an ion exchange capacity values (IEC) for Li+, Na+ and K+ which were found to be 1.98, 2.49 and 2.68 meq/g respectively. Based on the distribution coefficient values, PANI/Ti(IV) ISS conducting polymer based ion exchange material was found to be selective for the removal of Pb2+ ion, and the Kd value of 493.02 mL/g for Pb2+ ion from a mixture of toxic metal ions. Pb(II)ion from a synthetic mixture can be removed quantitatively by using PANI/Ti(IV) ISS and it is a promising candidate for ion selective electrode membrane studies.

description: A term first coined by Mott back in 1968 a `pseudogap' is the depletion of the electronic density of states at the Fermi level, and pseudogaps have been observed in many systems. However, since the discovery of the high temperature superconductors (HTSC) in 1986, the central role attributed to the pseudogap in these systems has meant that by many researchers now associate the term pseudogap exclusively with the HTSC phenomenon. Recently, the problem has got a lot of new attention with the rediscovery of two distinct energy scales (`two-gap scenario') and charge density waves patterns in the cuprates. Despite many excellent reviews on the pseudogap phenomenon in HTSC, published from its very discovery up to now, the mechanism of the pseudogap and its relation to superconductivity are still open questions. The present review represents a contribution dealing with the pseudogap, focusing on results from angle resolved photoemission spectroscopy (ARPES) and ends up with the conclusion that the pseudogap in cuprates is a complex phenomenon which includes at least three different `intertwined' orders: spin and charge density waves and preformed pairs, which appears in different parts of the phase diagram. The density waves in cuprates are competing to superconductivity for the electronic states but, on the other hand, should drive the electronic structure to vicinity of Lifshitz transition, that could be a key similarity between the superconducting cuprates and iron based superconductors. One may also note that since the pseudogap in cuprates has multiple origins there is no need to recoin the term suggested by Mott.

description: Chromatin modulators are emerging as attractive drug targets, given their widespread implication in human cancers and susceptibility to pharmacological inhibition. Here we establish the histone methyltransferase G9a/EHMT2 as a selective regulator of fast proliferating myeloid progenitors with no discernible function in hematopoietic stem cells (HSCs). In mouse models of acute myeloid leukemia (AML), loss of G9a significantly delays disease progression and reduces leukemia stem cell (LSC) frequency. We connect this function of G9a to its methyltransferase activity and its interaction with the leukemogenic transcription factor HoxA9 and provide evidence that primary human AML cells are sensitive to G9A inhibition. Our results highlight a clinical potential of G9A inhibition as a means to counteract the proliferation and self-renewal of AML cells by attenuating HoxA9-dependent transcription.

description: Textile wastewater effluents carry synthetic dyes resulting in potential hazards to the environment; hence such dyes need to be removed from the water bodies. In present research work, disperse dyes were degraded through coagulation using alum (Al2(SO4)3.18H2O) as a coagulant. Four dyes namely coralene navy blue EMRD, coralene red 6B, coralene orange 3R and coralene scarlet RR were used in the present research work and their removal from the wastewater was determined. The effects of initial pH, coagulant dose, initial dye concentration, temperature and time of reaction were tested to maximise decolourisation yield. Results of the experiments showed that the optimum pH for coagulation was 9 for each dye with up to 99% colour removal. By increasing the dose of alum Al2(SO4)3.18H2O, dye decolourisation was increased and maximum dye removal was observed when 1000 ppm of Al2(SO4)3.18H2O was used. When 100 ppm synthetic dye solution was prepared, up to 99% colour removal was achieved at optimal conditions i.e pH = 9, 1000 ppm of coagulant at 100°C with 50 min reaction time. Coralene navy blue EMRD presented nearly 70% colour removal with lowest dose of alum (200ppm) at 40°C. About 80% dye degradation was observed for coralene orange 3R within 10 min of reaction time. Thus Al2(SO4)3.18H2O was found to be efficient coagulant for the treatment of wastewater containing disperse dyes with about 50% reduction in conductivity and upto 75% removal in TDS of wastewater. Sludge volume settled after 1 hour of reaction time was 140 mL/500 mL. On the basis of obtained results, it was concluded that the wastewater can be treated using Al2(SO4)3.18H2O as coagulant.

description: The increasing levels of CO2 in the atmosphere and its consequential impact on global warming is driving many research groups to develop ways to use CO2 as raw material. For example, to produce feedstocks, or fuels. A wide variety of approaches to carbon dioxide utilisation have been reported employing homogeneous catalysis, heterogeneous catalysis, photocatalysis, photoreduction and electrochemical reduction.Besides the reduction of greenhouse gases, by producing feedstocks using CO2 will greatly reduce our dependence of fossil fuels for chemical synthesis. Our previously reported electrochemical processes have proven to be successful in terms of electron transfer between substances at room temperature and atmospheric pressure.Atmospheric-pressure plasmas interacting with organic liquids offer a new possibility for chemical synthesis that remains largely unexplored. Here I reported the results obtained with a Jet device in which chemical reactions are triggered in an organic liquid by an atmospheric-pressure plasma.As a proof-of-concept, I considered the incorporation of CO2 into an alkyne to form a carboxylic acid. Here I explore plasma reduction. A CO2 saturated solution of trans-stilbene in Lithium Tetrafluoroborate (LiBF4), and Dimethylformamide (DMF). Argon DC plasma is used as a gaseous cathode to provide electrons for the reduction of CO2. Gas chromatography Mass Spectroscopy (GCMS) and Nuclear Magnetic Resonance (NMR) analysis indicate the formation of its corresponding carboxylic acid with good selectivity.

description: The research project focuses primarily on the identification and analysis of the entrepreneurial and business profile of gym and musculation center managers in Teresina, Piauí. The gym sector in the city has experienced significant growth in recent decades, driven by the increasing demand for health and wellness services, highlighting the relevance of investigating management practices in this context. The research adopts a mixed-methods approach, combining quantitative and qualitative methods, including geomarketing analysis, which allows the study of how geographic location influences business performance. The study also seeks to understand how the adoption of digital technologies, such as artificial intelligence, can optimize processes and enhance the competitiveness of gyms. By understanding the entrepreneurial skills and effective practices applied by managers, the project offers relevant contributions both to the theoretical advancement in the field of management and entrepreneurship and to the proposal of practical solutions aimed at the sustainable development of the gym sector in the capital of Piauí. The research also presents implications for the formulation of public policies that encourage innovation and local entrepreneurship.

description: We obtained six observations of PSR J1741-2054 using the $Chandra$ ACIS-S detector totaling $\sim$300 ks. By registering this new epoch of observations to an archival observation taken 3.2 years earlier using X-ray point sources in the field of view, we have measured the pulsar proper motion at $μ=109 \pm 10 {\rm mas\ yr}^{-1}$ in a direction consistent with the symmetry axis of the observed H$α$ nebula. We investigated the inferred past trajectory of the pulsar but find no compelling association with OB associations in which the progenitor may have originated. We confirm previous measurements of the pulsar spectrum as an absorbed power law with photon index $Γ$=2.68$\pm$0.04, plus a blackbody with an emission radius of (4.5$^{+3.2}_{-2.5})d_{0.38}$ km, for a DM-estimated distance of $0.38d_{0.38}$ kpc and a temperature of $61.7\pm3.0$ eV. Emission from the compact nebula is well described by an absorbed power law model with a photon index of $Γ$ = 1.67$\pm$0.06, while the diffuse emission seen as a trail extending northeast of the pulsar shows no evidence of synchrotron cooling. We also applied image deconvolution techniques to search for small-scale structures in the immediate vicinity of the pulsar, but found no conclusive evidence for such structures.

description: The YEATS domain, found in a number of chromatin-associated proteins, has recently been shown to have the capacity to bind histone lysine acetylation. Here, we show that the YEATS domain of Taf14, a member of key transcriptional and chromatin-modifying complexes in yeast, is a selective reader of histone H3 Lys9 acetylation (H3K9ac). Structural analysis reveals that acetylated Lys9 is sandwiched in an aromatic cage formed by F62 and W81. Disruption of this binding in cells impairs gene transcription and the DNA damage response. Our findings establish a highly conserved acetyllysine reader function for the YEATS domain protein family and highlight the significance of this interaction for Taf14.

description: Commissural axon guidance depends on a myriad of cues expressed by intermediate targets. Secreted semaphorins signal through neuropilin-2/plexin-A1 receptor complexes on post-crossing commissural axons to mediate floor plate repulsion in the mouse spinal cord. Here, we show that neuropilin-2/plexin-A1 are also coexpressed on commissural axons prior to midline crossing and can mediate precrossing semaphorin-induced repulsion in vitro. How premature semaphorin-induced repulsion of precrossing axons is suppressed in vivo is not known. We discovered that a novel source of floor plate-derived, but not axon-derived, neuropilin-2 is required for precrossing axon pathfinding. Floor plate-specific deletion of neuropilin-2 significantly reduces the presence of precrossing axons in the ventral spinal cord, which can be rescued by inhibiting plexin-A1 signaling in vivo. Our results show that floor plate-derived neuropilin-2 is developmentally regulated, functioning as a molecular sink to sequester semaphorins, preventing premature repulsion of precrossing axons prior to subsequent down-regulation, and allowing for semaphorin-mediated repulsion of post-crossing axons.

description: Almost every human activity in recent years relies either directly or indirectly on the smooth and efficient operation of the Internet. The Internet is an interconnection of multiple autonomous networks that work based on agreed upon policies between various institutions across the world. The network policies guiding an institution’s computer infrastructure both internally (such as firewall relationships) and externally (such as routing relationships) are developed by a diverse group of lawyers, accountants, network administrators, managers amongst others. Network policies developed by this group of individuals are usually done on a white-board in a graph-like format. It is however the responsibility of network administrators to translate and configure the various network policies that have been agreed upon. The configuration of these network policies are generally done on physical devices such as routers, domain name servers, firewalls and other middle boxes. The manual configuration process of such network policies is known to be tedious, time consuming and prone to human error which can lead to various network anomalies in the configuration commands. In recent years, many research projects and corporate organisations have to some level abstracted the network management process with emphasis on network devices (such as Cisco VIRL) or individual network policies (such as Propane).

description: We developed a method for genome-wide mapping of DNA excision repair named XR-seq (excision repair sequencing). Human nucleotide excision repair generates two incisions surrounding the site of damage, creating an ∼30-mer. In XR-seq, this fragment is isolated and subjected to high-throughput sequencing. We used XR-seq to produce stranded, nucleotide-resolution maps of repair of two UV-induced DNA damages in human cells: cyclobutane pyrimidine dimers (CPDs) and (6-4) pyrimidine–pyrimidone photoproducts [(6-4)PPs]. In wild-type cells, CPD repair was highly associated with transcription, specifically with the template strand. Experiments in cells defective in either transcription-coupled excision repair or general excision repair isolated the contribution of each pathway to the overall repair pattern and showed that transcription-coupled repair of both photoproducts occurs exclusively on the template strand. XR-seq maps capture transcription-coupled repair at sites of divergent gene promoters and bidirectional enhancer RNA (eRNA) production at enhancers. XR-seq data also uncovered the repair characteristics and novel sequence preferences of CPDs and (6-4)PPs. XR-seq and the resulting repair maps will facilitate studies of the effects of genomic location, chromatin context, transcription, and replication on DNA repair in human cells.

description: Histone H3.3 is a highly conserved histone H3 replacement variant in metazoans and has been implicated in many important biological processes, including cell differentiation and reprogramming. Germline and somatic mutations in H3.3 genomic incorporation pathway components or in H3.3 encoding genes have been associated with human congenital diseases and cancers, respectively. However, the role of H3.3 in mammalian development remains unclear. To address this question, we generated H3.3-null mouse models through classical genetic approaches. We found that H3.3 plays an essential role in mouse development. Complete depletion of H3.3 leads to developmental retardation and early embryonic lethality. At the cellular level, H3.3 loss triggers cell cycle suppression and cell death. Surprisingly, H3.3 depletion does not dramatically disrupt gene regulation in the developing embryo. Instead, H3.3 depletion causes dysfunction of heterochromatin structures at telomeres, centromeres, and pericentromeric regions of chromosomes, leading to mitotic defects. The resulting karyotypical abnormalities and DNA damage lead to p53 pathway activation. In summary, our results reveal that an important function of H3.3 is to support chromosomal heterochromatic structures, thus maintaining genome integrity during mammalian development.

description: Disinformation refers to false information that is spread with the intention of causing harm or creating uncertainty. For democracy in Europe, disinformation poses a significant challenge. Not least because artificial intelligence can generate and disseminate new and targeted information ever more quickly. This study conducted by the "Upgrade Democracy" project examined how people in the European Union perceive and respond to the issue of disinformation. The study reveals that a majority of people feel uncertain when it comes to assessing the truthfulness of information on the internet. Many have also encountered disinformation themselves. Over 80 percent of respondents in this survey expect both politics and social media platform operators to take more action against the spread of disinformation.

The data for this “Upgrade Democracy” study was collected through the Bertelsmann Stiftung’s Eupinions project. Four times a year, the team at Latana conducts an online survey on behalf of Bertelsmann in all 27 EU member states. The survey data used in this study was collected in March 2023 and involved 13,270 EU citizens aged between 16 and 70. Data is weighted by gender, age and region. However, due to the structure of the sample, additional separate values can only be shown for seven countries: Belgium, Germany, France, Italy, the Netherlands, Poland and Spain.

description: Chromosome translocations are well-established hallmarks of cancer cells and often occur at nonrandom sites in the genome. The molecular features that define recurrent chromosome breakpoints are largely unknown. Using a combination of bioinformatics, biochemical analysis, and cell-based assays, we identify here specific histone modifications as facilitators of chromosome breakage and translocations. We show enrichment of several histone modifications over clinically relevant translocation-prone genome regions. Experimental modulation of histone marks sensitizes genome regions to breakage by endonuclease challenge or irradiation and promotes formation of chromosome translocations of endogenous gene loci. Our results demonstrate that histone modifications predispose genome regions to chromosome breakage and translocations.

description: BK polyomavirus (BKPyV) and cytomegalovirus (CMV) are the main viral pathogens affecting the graft and recipient outcome after allogenic kidney transplantation. It has recently been found that infection with both viruses has a greater impact on kidney graft function than a single infection. We retrospectively analyzed a cohort of 723 recipients who received kidney transplantation between 2007 and 2015 after living and postmortal donation for differences in risk and outcome parameters regarding BKPyV (DNAemia) and CMV (CMV DNAemia) co-infection compared to sole viremias and to patients without viremia. Of all kidney allograft recipients in our cohort, 8.2% developed co-infection with BKPyV DNAemia and CMV DNAemia, 15.1% showed BKPyV viremia alone and 25.2% sole CMV DNAemia. Acute rejection was closely linked with co-infection (multivariable analysis, p = 0.001). Despite the fact that the estimated glomerular filtration rate of patients with co-infection was noticeably reduced compared to patients with BKV or CMV infection alone, transplant survival and patient survival were not significantly reduced. Co-infection with BKPyV and CMV in kidney transplanted patients is significantly associated with inferior allograft function. Since co-infection is strongly associated with acute rejection, co-infected individuals should be considered a risk collective.

title: Reality and consciousness : a study of selected novels of May Sinclair.
Creators: name: Theresa. Phillips, Mary
Publisher: name: University of Liverpool Repository

description: This dissertation considers selected novels of May Sinclair,in the light of her declared interest in the representat:ionN.of reality. It is written from a theoretical position which recognises that the reflection of reality in works of art ;s problematic, but which nevertheless maintains that works of fiction have some relationship with the real world. Using Bakhtin's concept of polyphony, as developed in his study of Dostoevsky's novels, it suggests that a novel is more open to the realitY,:r seeks to represent, in p~oportion to the multipl i.~..~.~f its voices. S, ne 1air cons ide red the re."r,esenta t ion of consc iousness to be the key element in trie representation of reality. The first chapter explores her' representation of consciousness in her novels, e~ploying a close formal analysis of voice and viewpoint, and demonstrating that even in her single consciousness novels, the consciousness of her characters is dialogic. The second chapter extends the study of Sinclair's treatment of consciousness to the more problematic area of the unconscious, demonstrating the variety of methods she employs, and her success in leaving open to the reader the interpretation of her characters' unconscious minds. The third chapter is a reader-orientated approach to the presence of irony in Sinclair's novels, arguing that ironic gaps and signals in the text allow the reader space to assert his/her own voice .. The final chapter interrogates Sinclair's representation of reality from a feminist position which challenges the cultural stereotypes, which inevitably construct even novels written from a feminist perspective, paying par~icular attention to the influence of contemporary.·psychology on Sinclair's representation of female characters. The dissertation .concludes 'by suggesting re.asons why even the feminist movement within literary'st-'~ies has largely failed to reawaken interest in Sinclair's novels. It suggests possible lines for further research and enters a plea for the re-publication of a wider ~ange of her novels.
