AbstractOne of the main challenges for healthy hydrocarbon yields from the production wells is the sand production, and its control assumes significant importance for successful production operations. The prime objective remains to control the sand production without compromising on the fluid flow rates. Sand production is conventionally associated with diverse heterogeneous formations, especially poorly consolidated formations. Scrutinizing fluid flow rates at different orientations of perforations is a valuable analysis in controlling the sand production. This study was conducted to examine the case of sand production in a few development wells from Malleshwaram field of the Krishna Godavari (KG) basin in south India and provide alternatives to arrest this sand production. The influence of oriented perforations on fluid flow rates to minimize sanding tendencies was examined. Sand grain diameter was estimated using the distribution plots of the grain sizes obtained from the photomicrographs, and the average value of the grain size was estimated around 100 μm. The fluid flow model was simulated for actual scenario in the hydrocarbon bearing Nandigama formation using finite element modeling (FEM). Sanding tendencies in these formations were studied at varying depletion rates. Critical draw down pressure (CDDP), which is a function of both critical bottom hole pressure and reservoir pore pressure, for well 1 and well 2 is estimated as 4650 Psi and 3400 Psi, respectively, at 0% depletion. CDDP was used to estimate the onset of sanding, and the flow rate for horizontal perforation was calculated as 0.024548 $${\mathrm{m}}^{3}$$

/sec. Strength parameters, namely the unconfined compressive strength (UCS) and cohesion, were also investigated in all the wells to decipher the formation strength and a possible linkage to sanding. These results present a completely fresh analysis of the sanding potential and the related parameters responsible for it in these formations. Fluid flow rates for the producing reservoir are studied at different set of oriented and sized perforations. It was observed that a hiked flow rate in horizontal perforations maintains the production in a safe and no-sanding zone. This study provides vital information and a workflow for similar heterogeneous complex formations for designing the well completions, augmenting economic production and reinforcing future reservoir management.
'Everyone would freak out, like they’ve never seen a boy before’: young people’s experiences of single-sex secondary schooling in NSW
Authors: Gannon Susanne 
Published: December 2023

AbstractAlthough gender expansive views are increasingly evident amongst young people, segregation according to binary notions of gender underpins the organisational structures of single-sex secondary schools. While claims of educational benefits are common, particularly for girls, gender is difficult to disentangle from socioeconomic advantage and other factors. Evidence suggests that such schools contribute to homogenised and limiting notions of gender. While some schools are moving towards desegregation in response to parental demand, little is known from the perspectives of young people in non-elite schools who have experienced segregated schooling. This paper turns to the accounts of 14 recent school leavers in NSW to consider the underpinning logics of segregated schooling, including the imbrication and erasure of socioeconomic dis/advantage, cultural, social, and locational factors that complicate claims about segregated schooling. Affective intensities of single-sex schooling are traced through micronarratives that touch on relations with peers, teachers, school spaces and practices, learning experiences, and their implications for gendered subjectivities and gender justice. Their accounts suggest that student experiences of segregated schooling are ambivalent and do not support claims of educational advantage and that configurations of single-sex schooling may be anachronistic for these times.
Accelerating and enhancing the generation of socioeconomic data to inform forced displacement policy and response
Authors: Brock Patrick Michael , Mugera Harriet Kasidi 
Published: December 2023

Abstract
There are now an estimated 114 million forcibly displaced people worldwide, some 88% of whom are in low- and middle-income countries. For governments and international organizations to design effective policies and responses, they require comparable and accessible socioeconomic data on those affected by forced displacement, including host communities. Such data is required to understand needs, as well as interactions between complex drivers of displacement and barriers to durable solutions. However, high-quality data of this kind takes time to collect and is costly. Can the ever-increasing volume of open data and evolving innovative techniques accelerate and enhance its generation? Are there applications of alternative data sources, advanced statistics, and machine-learning that could be adapted for forced displacement settings, considering their specific legal and ethical dimensions? As a catalytic bridge between the World Bank and UNHCR, the Joint Data Center on Forced Displacement convened a workshop to answer these questions. This paper summarizes the emergent messages from the workshop and recommendations for future areas of focus and ways forward for the community of practice on socioeconomic data on forced displacement. Three recommended areas of future focus are: enhancing and optimizing household survey sampling approaches; estimating forced displacement socioeconomic indicators from alternative data sources; and amplifying data accessibility and discoverability. Three key features of the recommended approach are: strong complementarity with the existing data-collection-to-use-pipeline; data responsibility built-in and tailored to forced displacement contexts; and iterative assessment of operational relevance to ensure continuous focus on improving outcomes for those affected by forced displacement.
ESPIONAGE LAW IN THE UK AND AUSTRALIA: BALANCING EFFECTIVENESS AND APPROPRIATENESS
Authors: Kendall Sarah 
Published: December 2023

AbstractThis article engages in a comparative analysis of espionage law in the UK and Australia to determine whether the laws in each country are effective and appropriate. It finds that, while the espionage laws in both countries are largely capable of effectively addressing modern espionage, this has come at the expense of appropriateness – specifically, aspects of the laws in both jurisdictions are complex, uncertain and overly broad, and defences and other safeguards for legitimate conduct have limitations. The article argues that, while the effectiveness of espionage (and other national security) laws is an important consideration, this must be balanced with appropriateness to ensure that core rule of law values and legal principles are not undermined.

AbstractBackgroundThe modulation of brain circuits of emotion is a promising pathway to treat borderline personality disorder (BPD). Precise and scalable approaches have yet to be established. Two studies investigating the amygdala-related electrical fingerprint (Amyg-EFP) in BPD are presented: one study addressing the deep-brain correlates of Amyg-EFP, and a second study investigating neurofeedback (NF) as a means to improve brain self-regulation.MethodsStudy 1 combined electroencephalography (EEG) and simultaneous functional magnetic resonance imaging to investigate the replicability of Amyg-EFP-related brain activation found in the reference dataset (N = 24 healthy subjects, 8 female; re-analysis of published data) in the replication dataset (N = 16 female individuals with BPD). In the replication dataset, we additionally explored how the Amyg-EFP would map to neural circuits defined by the research domain criteria. Study 2 investigated a 10-session Amyg-EFP NF training in parallel to a 12-weeks residential dialectical behavior therapy (DBT) program. Fifteen patients with BPD completed the training, N = 15 matched patients served as DBT-only controls.ResultsStudy 1 replicated previous findings and showed significant amygdala blood oxygenation level dependent activation in a whole-brain regression analysis with the Amyg-EFP. Neurocircuitry activation (negative affect, salience, and cognitive control) was correlated with the Amyg-EFP signal. Study 2 showed Amyg-EFP modulation with NF training, but patients received reversed feedback for technical reasons, which limited interpretation of results.ConclusionsRecorded via scalp EEG, the Amyg-EFP picks up brain activation of high relevance for emotion. Administering Amyg-EFP NF in addition to standardized BPD treatment was shown to be feasible. Clinical utility remains to be investigated.
58 Hippocampal Subregions Predict Executive Function Across the Adult Lifespan

Published: December 2023

Objective:Executive function is known to decline in later life, largely attributed to structural and functional changes in the prefrontal cortex. However, other regions of the brain are integral to executive functioning, including the hippocampus. The hippocampus plays a large role in memory but its intricate connections to limbic regions including the prefrontal cortex likely underlies associations between the hippocampus and executive functions. Due to the hippocampus’ complex structure, hippocampal subregions may be differentially associated with executive function, but this possibility remains largely unexplored. Therefore, we examined the association between volume of the hippocampus and its subregions with executive function to understand these relationships across the adult lifespan.Participants and Methods:The study included 32 healthy, community-dwelling participants (age range = 18-81, mean age = 51.06 ± 20.98, 91% white, 72% female) who received a 3-Tesla magnetic resonance imaging (MRI) scan and completed a cognitive battery. We calculated an executive composite based on Trail Making Test Part B and the interference score from the Stroop Color and Word Test. Freesurfer (version 5.3) as used to quantify total hippocampal volume and subfield volumes for CA1, CA2-3, CA4-dentate gyrus, subiculum, and presubiculum. We conducted mixed-effects regression analyses with total hippocampal and subfield volume, age group (young, middle-aged, and older), and their interaction predicting the executive function composite, controlling for total intracranial volume.Results:Larger hippocampal subregion volumes in CA1 (p = 0.03), the subiculum (p = 0.01), and the CA4-dentate gyrus (p = 0.04) predicted better executive function. Total hippocampal volume and the presubiculum were not significantly associated with the executive function composite. The age group interaction was not significant for any of the models. Follow-up analyses by hemisphere showed that the effects were right lateralized in CA1and CA4-dentate gyrus, and bilateral in the subiculum.Conclusions:These data support the literature demonstrating the involvement of the hippocampus in executive function and demonstrates variation across hippocampal subfields. The lack of significant age interactions suggests these relationships may not differ across the lifespan, although this finding would need to be replicated in larger samples. These findings support previous literature showing CA4-dentate gyrus’ association with neurogenesis may facilitate better executive function by increasing connection strength among CA1, CA2-3, and the frontal cortex. This study contributes to our understanding of how specific hippocampal subregions relate to executive function, which has both clinical and research implications.
9 The Relationship Between Depressive Mood and Mini Mental Status Examination Scores in Individuals with Heart Failure

Published: December 2023

Objective:Heart failure occurs when the heart is unable to support a flow of blood that meets the body’s needs, ultimately resulting in decreased oxygenation throughout the body— including the brain. Results of previous research suggest that individuals with heart failure exhibit both localized and diffuse neuropsychological deficits. The aims of this study are to meta-analytically examine a) the performance of participants with heart-failure and healthy controls on the Mini Mental State Examination (MMSE), a neuropsychological test of general cognition, and b) the role of depressive mood as a potential moderator of performance on the MMSE in these participants.Participants and Methods:Two researchers independently searched eight databases for articles that examined the neuropsychological functioning of patients with heart failure.Inclusion criteria identified studies that had a heart failure group with a comparable control group and reported on neuropsychological assessment for both groups. Studies were excluded if a heart failure group had any other type of major organ failure or if the comparison was between different classes of heart failure rather than between a heart failure group and healthy controls.Results:A meta-analysis using a random-effects model revealed a statistically significant and large effect size estimate (g= 0.727, p <.001) CI [.331, 1.123]. The heterogeneity was found to be statistically significant and in the large range, I2 = 83.027%, tau2 = .155, p < .001. A meta-regression analyzing the relationship between depressive mood and MMSE effect size estimates was statistically significant, Q residual = 8.715, df = 3, p = .03.Conclusions:This study is the first to examine the relationship between depressive mood and general cognitive status (as measured by the MMSE) in participants with heart failure. The strong relationship between cognitive status and heart failure, and the role of depression in explaining a statistically significant portion of the heterogeneity in the relationship seen in primary studies, highlights the importance of accurately assessing depression when studying the effect of heart failure on cognition. Further research needs to examine the impact of depression on quality of life in patients with heart failure as potentially mediated by difficulties in cognition.
TheEscribanoof Babel: Power, Exile, and Enslavement in the Venezuelan Llanos During the War of Independence (1806–1833)
Authors: Vergara Sierra Ana Joanna 
Published: December 2023

AbstractThis article traces the professional life of Rafael Almarza, the last royal escribano (notary) of Mérida in the captaincy of Venezuela, and his role in undermining monarchical authority among the enslaved community displaced in the plains region (Los Llanos) during the war of independence in 1814-18. Despite their status as minor officials within the Spanish imperial bureaucracy, notaries, through the records they made, helped to establish legally binding truths underlying everyday actions, making them influential agents of colonial rule in the community they served, particularly among those seeking notarial documents to obtain freedom. During the battles for independence, escribanos like Almarza facilitated the transition of sovereignty and created documents that fomented the independence cause among enslaved individuals during the years of total war. By examining the manumission documents found in the notarial book Almarza kept during exile, the author of this article shows the importance of enslaved people in granting legitimacy to the emerging leadership of José Antonio Páez and the Republican project. At the same time, this study aims to provide a new look at manumission during the early stages of nation-building and the involvement of underrepresented groups in this process.

AbstractNon‐methane volatile organic compounds (NMVOCs) have a significant impact on air quality in urban areas. Detecting NMVOCs emission with its proxy HCHO on urban scales from space, however, has been limited by the lack of discernible enhancement. Here we show clear urban HCHO plumes from 16 cities over the globe by rotating TROPOspheric Monitoring Instrument HCHO pixels according to wind directions. We fit the downwind structure of the plumes with the exponentially modified Gaussian approach to quantify urban HCHO effective production rates between 7.0 and 88.5 mol s−1. Our results are in line with total NMVOC emissions from the EDGAR inventory (r = 0.76). Our work offers a new measure of total NMVOC emissions from urban areas and highlights the potential of satellite HCHO data to provide new information for monitoring urban air quality.
Developing ophthalmology in Cambodia

Published: December 2023

AbstractOver 180,000 Cambodian people are blind and a further 10,000 suffer avoidable blindness each year. Ninety percent of this blindness is avoidable, 79% is curable and 11% is preventable. Three-quarters of this blindness is due to cataracts and the remainder is due to uncorrected vision, glaucoma, corneal scarring and pterygium. The Khmer Sight Foundation (KSF) is a charity reincarnated by Professor Sunil Shah and Sean Ngu. Its mission is to deliver a sustainable eye care model for the country. KSF takes a three pronged approach to this. It is working to develop sustainable eye-care within the country through building physical infrastructure. The second approach is to impact the current cataract backlog of over 300,000 patients with the aid of international support. Thirdly, KSF is paving the way for the next generation through the development of an optometry education programme and training of Cambodian ophthalmologists. Here we present the workings of KSF, clinical cases we have encountered and elaborate upon the future goals of this charity.

Published: December 2023

AbstractCoastal vegetated ecosystems are acknowledged for their capacity to sequester organic carbon (OC), known as blue C. Yet, blue C global accounting is incomplete, with major gaps in southern hemisphere data. It also shows a large variability suggesting that the interaction between environmental and biological drivers is important at the local scale. In southwest Atlantic salt marshes, to account for the space occupied by crab burrows, it is key to avoid overestimates. Here we found that southern southwest Atlantic salt marshes store on average 42.43 (SE = 27.56) Mg OC·ha−1 (40.74 (SE = 2.7) in belowground) and bury in average 47.62 g OC·m−2·yr−1 (ranging from 7.38 to 204.21). Accretion rates, granulometry, plant species and burrowing crabs were identified as the main factors in determining belowground OC stocks. These data lead to an updated global estimation for stocks in salt marshes of 185.89 Mg OC·ha−1 (n = 743; SE = 4.92) and a C burial rate of 199.61 g OC·m−2·yr−1 (n = 193; SE = 16.04), which are lower than previous estimates.

Published: December 2023

Indium antimonide bismide (InSbBi) has emerged as a highly promising material for long-wavelength infrared photodetection devices due to its unique small energy bandgap (&lt;0.17 eV) compared to existing III–V compound semiconductors. Despite its potential, experimental studies on InSbBi are still incomplete and scarce. Furthermore, the challenges associated with incorporating Bi and producing high-quality, defect-free samples are yet to be adequately addressed. To tackle these issues, we systematically investigated the growth of InSbBi on a GaAs substrate in this study. We incorporated up to 3.4% of Bi into InSbBi material. Our research contributes significantly to the field by demonstrating a technique for growing high-quality InSbBi material with Bi content of up to 2.3%, which is free of droplets and features a smooth surface. We achieved this goal by dynamically adjusting the Sb flux, carefully controlling the interplay between the Bi flux and the growth temperature, and implementing a post-growth annealing process. Our work is crucial for developing InSbBi technology as it contributes to the understanding of the growth process and surface morphology of InSbBi. Moreover, our results provide a path toward producing high-quality InSbBi samples.
Supersonically expanded sodium metal-dilute halogen gas interactions. The importance of reaction populated and energy storing reservoir states and population inversion created amplification in Na2
Authors: Gole James L. , Dixon David A. 
Published: December 2023

The reactions of Cl, Br, and I with Nan=2,3 produced in a supersonic expansion form Na2* and Na* excited states extending across the visible and ultraviolet regions. Emission in the region extending from 410 to 600 nm indicates selectively formed excited state Na2 emission features. Experimental evidence suggests that this emission is associated with Na3 + X reactions. Broadband (0.5 cm−1) laser measurements demonstrate gain (population inversion) for select features at∼524–528(1%), ∼492(0.3%), and ∼458.7–461(0.8%) nm. Single mode (0.007 cm−1) measurements extending from 528.03 to 527.63 nm demonstrate amplification involving five to six individual rovibronic levels with a maximum gain close to 3% recorded at 527.9 nm. The observed gain is associated with select transitions from levels of the Na2 11Πu state populated, via identified curve crossings, through collision induced transfer from long-lived Na2 21Σg+ and 11Πg reservoir states. Collision induced population buildup in the lowest vibrational levels of these reservoir states and collision induced transfer to the Na2 11Πu state create a population inversion in transitions to the X 1Σg+ state of Na2. The observed amplification is aided by rapid vibrational and rotational relaxation in both the Na2 ground and excited reservoir states producing amplifiers in the visible region like the HF amplifier in the infrared. This study suggests the importance of reaction populated and energy storing long-lived reservoir states in small sodium molecule combustion processes and indicates the potential for providing new short wavelength visible and ultraviolet amplifiers for future laser-based chemical propulsion concepts.
