Education of Patients With Atrial Fibrillation and Evaluation of the Efficacy of a Mobile Virtual Patient Environment: Protocol for a Multicenter Pseudorandomized Controlled Trial.

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia and is a leading cause of mortality and morbidity. Patient knowledge about AF and its management is paramount but often limited. Patients need to be appropriately informed about treatment options, medicinal adherence, and potential consequences of nonadherence, while also understanding treatment goals and expectations from it. Mobile health apps have experienced an explosion both in their availability and acceptance as "soft interventions" for patient engagement and education; however, the prolific nature of such solutions revealed a gap in the evidence base regarding their efficacy and impact. Virtual patients (VPs), interactive computer simulations, have been used as learning activities in modern health care education. VPs demonstrably improved cognitive and behavioral skills; hence, they have been effectively implemented across undergraduate and postgraduate curricula. However, their application in patient education has been rather limited so far. This work aims to implement and evaluate the efficacy of a mobile-deployed VP regimen for the education and engagement of patients with AF on crucial topics regarding their condition. A mobile VP app is being developed with the goal of each VP being a simple scenario with a set goal and very specific messages and will be subsequently attempted and evaluated. A mobile VP player app is being developed so as to be used for the design of 3 educational scenarios for AF management. A pseudorandomized controlled trial for the efficacy of VPs is planned to be executed at 3 sites in Greece, Ukraine, and Kazakhstan for patients with AF. The Welch t test will be used to demonstrate the performance of patients' evaluation of the VP experience. Our study is at the development stage. A preliminary study regarding the system's development and feasibility was initiated in December 2022. The results of our study are expected to be available in 2024 or when the needed sample size is achieved. This study aims to evaluate and demonstrate the first significant evidence for the value of VP resources in outreach and training endeavors for empowering and patients with AF and fostering healthy habits among them.

Silent domestication of wildlife in the Anthropocene: The mallard as a case study

In the Anthropocene, human activities have been a dominant force affecting wildlife, natural habitats, and climate worldwide. Over time, increasing incidences of wildlife-human interactions may have positive outcomes for some generalist species, but studies continue to uncover that most predictably these generalist wild species also suffer from such interactions. In particular, the line between domestic and wild continues to blur as gene flow between these groups intensifies in the Anthropocene. We explore the meaning of wildness, focusing on the mallard, currently the most abundant duck species in the world. Mallard has been connected to humans for tens of thousands of years. Considered an exemplary generalist species with the capacity to adapt to rapidly changing environments, evidence gathered from a variety of disciplines suggests that some management efforts over the last centuries have resulted in the deterioration of the mallard's prolific nature, and that the apparent success in terms of current population size and wide distribution could mask a genetic collapse. Highlighting warning signs from the mallard system, in this Perspectives paper we discuss how active management of habitats and populations runs the risk of compromising species' wildness, and we suggest precautionary and counter-measures in the context of species management and conservation.

Encountering grasslands: a collective approach to urban biodiversity

While the prolific nature of many grass and herbaceous species in urban parks offers an opportunity to cultivate more biodiverse and dynamic grasslands, widespread maintenance practices and complex cultural, economic, and bureaucratic forces often result in the undervaluing and regular destruction of these plant species. The research described in this paper reimagines the way grassy landscapes are cared for and understood in urban environments. Located in an urban park in inner Sydney, Australia, and using design research methods of observation, physical care, storytelling and installation, the research proposes three “frames of care” to assist landscape architects and other spatial designers to engage with communities at a local level. The frames have the potential to expand collective understandings of grassland communities, test alternative maintenance practices, and better support urban biodiversity and seasonal flux. With acknowledgment to the complexities of urban sites such as these, experimental installation provided a promising space to meaningfully engage with the local community and build a foundation to generate greater reciprocity between humans and non-humans of the site.

Mutation Analysis and Restriction Site Mapping of GDF9 in Indonesian Bligon Goat

Bligon goat is one of the crossbred goats raised in Indonesia, which has a prolific nature, potentially increasing the economic benefits. The gene that particularly influences prolific traits is Growth Differentiation Factor 9 (GDF9). This study aims to identify the mutation analysis (SNPs and amino acid changes) and restriction enzymes map in the GDF9 of Bligon goats. Six pairs of primers were used to amplify target sequences of GDF9 by polymerase chain reaction method and continued by sequencing. The sequence products were analyzed to get information on the SNPs and restriction enzyme (RE) around the SNPs for genotyping by PCR-RFLP method. A total of 15 SNPs were found in position g.1956A>C, g.2248G>T, g.2470A>T, g.2172DelA (shift T, Heterozygote), g.2807C>T, g.2919C>T, g.2996C>T, g.3615T>C, g.3855A>C, g.3879A>G, g.3924A>G, g.3943G>T, g.3969G>A, g.3981G>A, and g.4314C>T. Eight out of fifteen SNPs are located at the exon. Thus, the amino acid shows one synonymous at Exon 1 (Leucine to Leucine) and seven non synonymous at exon 2 with varied amino acid alteration (Valine to Alanine, Glutamine to Proline, Lysine to Arginine, Lysine to Arginine, Glutamine to Histidine, Arginine to Lysine, and Serine to Asparagine, respectively). Two SNPs at position g.1956A>C in Exon 1 and g.3855A>C in exon 2 show the homozygote CC and heterozygote AC. The most sample at those two position 67% and 83% homozygote type, respectively. Recognitions of site restriction enzymes BsaI and BsmAI were found at g.1956A>C or g.667C>M (Exon I). SNP g.3855A>C or g.2566C>M was recognized by three restriction enzymes (MspI, HapII, and HpaII). Two SNPs were not recognized by the restriction enzyme, and two other SNPs have more than 12 fragmented sequences, and as a consequence, it is very difficult to analyze the genotype. In conclusion, fifteen site mutations were identified; however, only two potential genetic markers with transversion mutations in Exon 1 and Exon 2 were recognized by restriction enzymes (BsaI, HapII, and MspI). These enzymes were recommended as candidate markers for further genotype identification using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method.

153 Comparison of cortisol concentrations between traditional group therapy and equine assisted psychotherapy for substance use disorder residential treatment patients

Equine assisted psychotherapy (EAP) is emerging as an effective supplemental substance use disorder (SUD) treatment due to documented improvements in treatment retention, patient-therapist alliances, and patient communication skills within the therapeutic environment. Benefits are attributed to decreased cortisol concentrations associated with horse interaction during the therapy process, however, there is limited research on stress parameters related to EAP during SUD recovery. Due to the prolific nature of this disorder, there is an urgency in exploring effective treatment options for SUD. Therefore, the purpose of this study was to investigate concentrations of cortisol in SUD patients within a residential treatment program participating in EAP compared with those participating in traditional group therapy. Salivary cortisol samples were collected from 2 sample populations of young adults: A) residential SUD patients (n = 18) before and after 2 successive weeks of EAP-supplemented therapy sessions and B) residential population of SUD patients (n = 5) before and after 2 successive weeks of traditional group therapy sessions. The impacts of treatment, week of sampling, and treatment by week interactions were analyzedusing a mixed linear model in SAS. Significance level was set at 0.05. No significant impacts of therapy type (P = 0.74), week of sampling (P = 0.69), or any week by treatment interactions (P = 0.86) on patient cortisol concentrations were observed over the 2 week period. Results indicate that despite the therapeutic environment moving to an outdoor setting and the inclusion of exercise in the form of horseback riding within the EAP sessions that EAP did not introduce additional stress responses reflected in the cortisol measures than that seen within the traditional therapeutic setting. As such, EAP presents an opportunity to offer an alternative therapeutic experience where traditional approaches may have faltered, however, further research is needed looking at a larger sample population and additional physiological measures to determine the complete physiological impact this therapy has on SUD patients in comparison to other forms of therapeutic interventions.

Relationship between Physical Performance and Prolific Traits of Peranakan Etawa (PE) Goats Seen in Menda Kencana Farm, Semarang Regency

This study aimed to analyze the relationship between physical performance and prolificacy by examining 11 multiparous PE goats from Menda Kencana farm Semarang Regency. The data obtained for research comprised both prolific traits and the performance of the chosen sample of goats, which included body length (BL), body height (BH), chest circumference (CC), and hip width (HW). This research is categorized as survey research with the sampling method determined through purposive sampling, where the sample is determined intentionally, and the data used is primary data. Data were analyzed by simple linear regression analysis. The results of regression analysis of CC and HW each had a highly significant relationship (P<0.01) with the prolific nature following the regression line equations CC = 80.39 + 7.34D cm (R2= 56%) and LP = 14.17 + 3.64D cm (R2= 60.3%). However, BL and BH were not significantly associated with prolific traits (P>0.05). It is concluded that physical performance in the form of chest circumference and hip width is directly proportional to prolific traits, indicating that the greater the chest circumference and hip width, the higher the chance of PE goats bearing twins.

Zebrafish: A Pharmacological Model for Learning and Memory Research.

Learning and memory are essential to organism survival and are conserved across various species, especially vertebrates. Cognitive studies involving learning and memory require using appropriate model organisms to translate relevant findings to humans. Zebrafish are becoming increasingly popular as one of the animal models for neurodegenerative diseases due to their low maintenance cost, prolific nature and amenability to genetic manipulation. More importantly, zebrafish exhibit a repertoire of neurobehaviors comparable to humans. In this review, we discuss the forms of learning and memory abilities in zebrafish and the tests used to evaluate the neurobehaviors in this species. In addition, the pharmacological studies that used zebrafish as models to screen for the effects of neuroprotective and neurotoxic compounds on cognitive performance will be summarized here. Lastly, we discuss the challenges and perspectives in establishing zebrafish as a robust model for cognitive research involving learning and memory. Zebrafish are becoming an indispensable model in learning and memory research for screening neuroprotective agents against cognitive impairment.

The Role of a Rich Landscape Vegetation on kob Antelope (Kobus kob) Group Feeding Activity in Bouba Ndjidda National Park, North Region, Cameroon

Thorough knowledge of the ecological requirements of ungulates provides the basis for the formulation of an appropriate programme of management actions directed at that species. More so, the identification of the minimum habitat requirements for a species is essential before specific management actions can be instituted. However, the relationship between antelopes and habitat plays a crucial role in the ecology of any species. The association between a herbivore and its habitat not only encompasses the availability of preferred food plants and their particular growth stages in its home range, it is also intimately linked to other features of the habitat. Hence, the key objective of this study was to assess the role of landscape vegetation on antelopes’ sustainability. Data collection was initiated immediately after a thorough study was done. The kob antelopes groups were visited regularly to record both feeding activity and ecological factors. The study showed a significance between kob antelope group and vegetation, X2 = 7.383 df=8, P<0.05. The antelope-group strength was dominated by 1-5 antelopes 89%, but larger group-sizes were equally recorded though not common. The three vegetation types most used by the antelopes were grassland 49%, shrub-land 36%, and forest patches 11%. Nonetheless, the antelope-group activity showed a significance on vegetation type X2 = 11.510 df=4, P<0.05. The most significant animal activities recorded were movement 49%, feeding 35%, and resting 16% respectively. Similarly, antelope-group activity revealed a significance on photo-period X2 = 5.348 df=2, P<0.05. Additionally, the antelope-group size showed a significance on landscape X2 = 7.364 df=8, P<0.05. Bouba ndjidda national park in the northern region of Cameroon has three landscape types useful to the kob antelopes, flat 73%, slope 25%, and hill 2% respectively. More so, there was a positive correlation significance between vegetation and food resources r = 0.248, P<0.05. The landscape of the national park has very little escapement that could obstruct movement of these mediumsized antelopes. Furthermore, their vigilance, speed against predators, and prolific nature might help the antelope achieve a high population in the national park in future. Most of these antelopes have received very little research attention, however, more study is needed to explore the social organization, feeding and population ecology.

Bacterial Succession during Vermicomposting of Silver Wattle (Acacia dealbata Link).

Vermicomposting is the process of organic waste degradation through interactions between earthworms and microbes. A variety of organic wastes can be vermicomposted, producing a nutrient-rich final product that can be used as a soil biofertilizer. Giving the prolific invasive nature of the Australian silver wattle Acacia dealbata Link in Europe, it is important to find alternatives for its sustainable use. However, optimization of vermicomposting needs further comprehension of the fundamental microbial processes. Here, we characterized bacterial succession during the vermicomposting of silver wattle during 56 days using the earthworm species Eisenia andrei. We observed significant differences in α- and β-diversity between fresh silver wattle (day 0) and days 14 and 28, while the bacterial community seemed more stable between days 28 and 56. Accordingly, during the first 28 days, a higher number of taxa experienced significant changes in relative abundance. A microbiome core composed of 10 amplicon sequence variants was identified during the vermicomposting of silver wattle (days 14 to 56). Finally, predicted functional profiles of genes involved in cellulose metabolism, nitrification, and salicylic acid also changed significantly during vermicomposting. This study, hence, provides detailed insights of the bacterial succession occurring during vermicomposting of the silver wattle and the characteristics of its final product as a sustainable plant biofertilizer.

Probiotics Interactions and the Modulation of Major Signalling Pathways in Host Model Organism Caenorhabditis elegans.

Microorganisms live in the human digestive system and the gut microbiome constitutes part of our prime determining component for healthy aging and wellness. Gut microbiota has broad influences on its host, beginning from the digestion of food and nutrients absorption to protective roles against invading pathogens and host immune system regulation. Dysbiosis of the gut microbial composition has been linked to numerous diseases and there is a need to have a better grasp on what makes a 'good' gut microbiome. Caenorhabditiselegans(C.elegans) model organism is consideredas a well-suitedin-vivomodel system and, is at the frontline of probiotic research because of its well-defined characteristics and prolific nature. Most importantly,C.elegansfeeds on bacteria, which speeds up manipulations and investigations in probiotics research tremendously. With its unique salient features of short lifespan, and ease of propagation, different unknown probiotics biological roles can be measured at an organism level with precision in the form of worm's stress responses, survivability, and lifespan. In this review, new insights on the different mechanisms underlying the establishment of probiotics regulations of conserved signalling pathways such as p38 MAPK/SKN-1, DAF-2/DAF-16, and JNK-1/DAF-16 is highlighted based on information obtained from C. elegans studies. Along with the current state of knowledge and the uniqueness of C. elegans as a model organism, explorations of its future contribution and scope in synthetic biology and probiotics engineering strains are also addressed. This is expected to strengthen our understanding of probiotics roles and to facilitate novel discovery and applications, for specific therapeutics against age-related disorders and various pathophysiological conditions.

PMSG in ewes: A Practical and Efficient Step for Superovulation

Ewes have a prolific nature, but in reality, the average number of lambs (litter size) is still around 120%. The application of the PMSG (Pregnant Mare Serum Gonadotrophyn) hormone aims as a superovulation agent for obtaining twins in one birth. PMSG is a non-pituitary gonadotrophyn hormone that has the same function as FSH ((Follicle Stimulating Hormone) and LH (Luteinizing Hormone) which stimulates follicular and ovulation growth. Various methods of applying the PMSG hormone to the ewes were quite diverse and produced different responses. Which method is considered the most practical and efficient is the main topic in this paper. Details of the discussion in this paper include the nature and biochemical characteristics of PMSG, the performance of PMSG as a superovulation agent, the comparison of PMSG with other reproductive hormones to the superovulation response in ruminants, and the impact of PMSG on superovulation in ewes.

Consumers preference for rabbit meat as a source of animal protein in selected Local Government Areas in Rivers State


 
 
 
 The study was designed to determine consumer’s preference for rabbit (Oryctolagus cuniclus)meat with respect to its production and consumption in Khana, Gokana, Tai and Eleme Local Government Areas (LGAs) making up the Ogoni Kingdom in Rivers State, Nigeria. A sample of 80 respondents (20 per LGA) were selected and interviewed using structured questionnaires. The data collected were analyzed using descriptive statistics such as frequency counts and percentages. The result indicated that the availability of animals reared or hunted in the LGAs apart from poultry were in the order of goat (47.5%), sheep (28.8%), rabbit (11.3%), grass-cutter (8.8%) and monkey (3.8%). Producer’s preference for rearing animals also followed a similar order. Demographic characteristics of the rabbit farmer showed that most of them were males (above 50 years) who had tertiary education and kept 1-20 rabbits both for family consumption and sales. Although more of the respondents(47.5%) were aware of rabbit as an animal, goats were more domesticated in the area but they indicated their readiness to increase the production and consumption of rabbit (77.5%).Further investigation revealed that consumers had high preference for goat and sheep meat,medium preference for rabbit and grass-cutter meat and low preference for meat from monkey. Among the factors identified that were capable of boosting rabbit production were the rich vegetation in the area, the ability of the rabbits to survive on roughages with little or no proprietary feeds, low cost of production, short gestation period and the high prolific nature of rabbits. It is therefore believed that with the good knowledge of goat and sheep production by most of the respondents in the area, which has some similarities with that of rabbit production, any effort targeted at improving the people’s preference for rabbit production and consumption in the LGAs (through radio jingles or seminars) will increase animal protein intake, create jobs, alleviate poverty and enhance rural livelihood
 
 
 

Aquifer potential of the transboundary crystalline-sedimentary complexes: from Northcentral Nigeria to Northwestern Cameroon border

ABSTRACT The aquifer system was apparently hidden but has been revealed as linked to transboundary aquifers; hence, additional info for data update of the International Groundwater Resources Assessment Center (IGRAC). The aquifer was explored for the purpose of Internationally Shared Aquifer Resource Management (ISARM). It advanced from fractured aquifers at upstream to the multilayered aquifer system toward downstream. The watershed was explored from Northcentral Nigeria to Cameroon border with electrical sounding. Geological/Hydrogeological details were locally concentrated at the center of the watershed via drilling program, aquifer tests, and hydrological modeling. Aquifer stress index (AQSI) of the region was reviewed from the existing global dataset. Results revealed aquifer provenances from crystalline and sedimentary complexes. The aquifers were relatively inferred at third and fourth geoelectrical layers at upstream and downstream, respectively. Generally, drilling operation showed depth as ≥50.0 m. Most boreholes showed drawdown of ≤5.0 m and transmissivity of ≥100 m2/day, signifying the prolific nature of the aquifer system and enormous groundwater recharge. The AQSI ≤ 0.1 signified a stress-free aquifer. Concentrations of solutes are within nutritional background, yet moderately hard with bicarbonate/carbonate concentrations that can degrade the irrigation quality. Precipitates (CaCO3) from limestone provenance may hamper borehole yields at downstream alluvium. Thus, injection of gypsum at the groundwater recharge zones is a certified remedial.

A brief history of demographic transition and population thought

”Demographic transition” is one of the most important concepts in understanding the modern history of population and health. The modernization of nations progressed as a drastic demographic shift occurred from a regime of high fertility and high mortality to that of low fertility and low mortality. Considering the long-term demographic changes, the paper presents a brief history of population thought from Malthusian theory at the end of the 18th century to the Sustainable Development Goals (SDGs) of the early 21st century. Malthus’ theory of population implied that living things have a prolific nature, although this idea was considered dangerous and not clearly stated at the time. It promoted the emergence of birth control movements and enabled Darwin to complete and publish his theory of evolution. Malthus, who pioneered the modern era, emphasized the contrast between population growth and food shortage. We, standing at the demise of the modern era, face new challenges, such as global resource constraints and environmental concerns, population aging to an unprecedented degree, coexistence of populations with still high and very low fertility, and new tides of international migration. The SDGs do not explicitly mention population trends, but the majority of the goals are substantially related to population and health.

First report of the occurrence of Asian citrus psyllid Diaphorina citri (Hemiptera: Liviidae), an invasive species in Nigeria, West Africa

The Asian citrus psyllid (ACP; Diaphorina citri) is the vector of Candidatus Liberibacter asiaticus (CLas) that is associated with the devastating Huanglongbing (HLB; citrus greening disease). This pest of Asian origin has spread into the Americas and more recently into a few countries in East Africa. During recent surveys, suspect ACP adults and nymphs were recorded for the first time infesting citrus trees in southwest Nigeria. Morphological identification and DNA barcoding confirmed the samples to be D. citri. Analysis of the obtained sequences revealed that the ACP recorded in Nigeria clustered with other taxa in the previously identified B1 clade that consists of populations from different continents. The presence of the endosymbionts Ca. Carsonella ruddii and Ca. Profftella armatura in ACP from Nigeria was also confirmed by PCR and Sanger sequencing. The ACP individuals were assayed for the presence of CLaf, CLam and CLas by qPCR, but none of the insects tested positive for any of the Liberibacters. The prolific nature of ACP and the tropical climate prevailing in the citrus-producing areas of Nigeria and other West African countries may favor its rapid spread and population increase, thus posing a grave threat to the sustainability of citriculture in these countries.

Reflexive renovation and the future of household sustainability: The role of media and imagination in household consumption

AbstractRecent scholarship illustrates the significant role media content plays in shaping home renovation outcomes, suggesting additional focus on the media–renovation dynamic is warranted in the face of increasing household consumption. Examining the reflexive characteristics of media‐engaged practices in renovation reveals the ways in which future household consumption practices are imagined and materially scripted during the design and construction phases of home renovation. Understanding these activities has the potential to contribute to the environmental sustainability of homes. The prolific nature of Australian home renovation activity is evident in the AU$33.3 billion spent annually and the diverse and widespread engagement with renovation media by homeowners. Television programmes, magazine content, websites, and apps reflect socio‐cultural trends towards large floor areas and additional energy‐intensive devices. Based on in‐depth interviews with 22 home renovators across Victoria, Australia, this article examines how media script the spatial and material dimensions of homes during renovation. Drawing on a social practices understanding of social life in households, the article uses the concept of reflexivity in renovation practices to show how renovators engage with media when reimagining their homes during renovations, subsequently shaping future practices and sustainability outcomes. Analysis demonstrates that features such as butler's pantries, back decks, and upgrades in appliances are in part scripted by the imagination–media dynamic. An argument is made for renovation media content to include a sustainability dimension in keeping with the key aspirations of homeowners—socially acceptable, aesthetically pleasing, financially efficient, and thermally comfortable homes.

Identifikasi Mutasi FecX Pada Gen BMP15 dan Pengaruhnya Terhadap Sifat Prolifik pada Kambing Lokal di Kabupaten Lombok Barat

The aims of this study were to identify the mutations of FecX gene in the local goats and to analyze its polymorphism as well as its influence on the prolific nature of the local goats in West Lombok Regency, Indonesia. The study was conducted in the Immunobiology Laboratory of Mataram University, using DNA isolated from 100 blood samples of local female goats which have given birth of once to three times. The methods used were PCR-RFLP method and the PCR products were digested with HinfI restriction enzyme (G|ANTC) then analyzed visually based on DNA banding patterns on 2% agarose gels. The frequency of allele and genotype obtained, were then analyzed through a comparison with the secondary data of litter size obtained from the local goat keepers information. The results showed that the gene mutation of FecXG produced two alleles: "wild-type" (+) sized of 110 bp and 31 bp, and the mutant allele (G) of 141 bp with the allele frequency of 0,965 and 0,035 respectively. Combinations of alleles in the gene BMP15 produced two genotypes, namely (a) genotype ++ (110 bp/110 bp) with a frequency of 0.93, with the average litter size of 1.59 ± 0.319, and (b) genotype G + (141bp/110 bp), with a frequency of 0.07 and with the average litter size of 1.65 ± 0.202. The results of this study indicated that mutation occurred in BMP15 gene, i.e. FecXG gene, the gene responsible for the prolificacy of animals studied. Furthermore there was a correlation between polymorphism of FecXG gene and the prolific nature of the local goats, which was predicted to lead the divergence in litter size of each local goat genotype

Ungani Oil Field, Canning Basin - Evaluation of a Dolomite Reservoir

Core supported study of the heterogeneous Ungani dolomite reservoir architecture is driving development drilling and upgrades to field resource estimates. Vuggy connected and macro non-connected pore space was directly measured over a 70m continuous core using 3D structural analysis of CT-scans. Plug density measurements indicate non-connected or sub-140 micron resolution contribution of around 1% to 2.5% (pu) for the tight matrix, but all remaining porosity potentially contributes to oil production. The high resolution core porosity data is vertically repositioned and upscaled to calibrate neutron-density and sonic petrophysically derived porosities which are inadequate to resolve productive zones using conventional reservoir cut-offs. Conditioned resistivity image data correlated exceptionally with directly measured connected porosities. Reservoir properties were extrapolated to all wells across the Ungani field giving field net/gross estimates of up to 63% and porosities over 30% pu in some vuggy and brecciaed zones. The heterogeneity and prolific nature of the uppermost 17m of reservoir had not been previously recognised due to poor log data coverage and access at the casing points. Recent re-analysis of this section at Ungani-3 with Chemostrat ICP-OES-MS analysis of ditch cuttings was instrumental in proposing additional drilling to re-target this zone. Mineralogy analysis is used to calculate rock grain densities and help calibrate neutron-density derived porosity logs over the Ungani field. Up-scaled core porosity correlates well with density and sonic porosity logs. Resistivity logs adjusted for minerology can also be used to predict porosity and support the use of resistivity image logs to identify vuggy zones and estimate porosity at a higher resolution than conventional logging tools. A field static model was populated with three facies distributed over vertical zones according to the distribution encountered in the core porosity analysis and well logs, and iteratively matched to the dynamic pressure data and field production history which exhibits field scale multi-Darcy horizontal permeability and protection from vertical water cut. Further drilling and downhole artificial lift is planned to extend field production rates to 3000 bbls/day. Increased confidence in this regionally developed reservoir is supporting further exploration of undrilled prospects in this immature and under-explored trend

The Diversity We Are Given: Community Economies and the Promise of Bataille

AbstractFor over 20 years J K Gibson‐Graham and the Community Economies Collective have endeavoured to reveal the diversity of economic practice already operative in our so‐called capitalist world. The aim of this paper is to further this ambition by illuminating an occlusion in Gibson‐Graham's own political vision. It argues that diversity, in Gibson‐Graham's thought, is primarily conceptualised as something produced. Drawing upon the work of George Bataille, this paper conceptualises the economy as a superlative and prodigal system of energy exchange that, by definition, is over‐productive and wasteful. In this framing, diversity is not the result of positive relations but emerges from the prolific nature of the general economy. The idea is developed through a discussion of the Detroit urban farming movement. Specifically it argues that the inefficient, redundant and wasteful nature of urban farming is an appropriation of potentialities resident within the general economy.
