Could China meet its emission reduction goal by CO2-EOR
Authors: Shannak Sa’d , Malov Artem 
Published: January 2021

Purpose
This paper aims to discuss opportunities for pairing the carbon dioxide (CO2) points of supply from stationary sources such as power plants, steel and cement production, coal to liquid plants and refineries, with potential oil reservoirs in China.

Design/methodology/approach
This study builds a linear optimization model to analyze the tradeoffs in developing CO2-enhance oil recovery (EOR) projects in China for a range of policy options to match points of supply with the points of demand (oil fields). The model works on optimizing CO2 application costs by meeting four principal components; CO2 storage, CO2 capture, transport costs and additional oil recovery.

Findings
This study reveals new opportunities and economic sources to feed CO2-EOR applications and offers reasonable options to supply CO2 for potential points of demand. Furthermore, power plants and coal to liquid industries had the most significant and economic contributions to potential CO2-EOR projects in China. Total annual emission reduction is expected to be 10% (based on 10 Gton annual emissions). The emission reductions and potential CO2 storage from the different industries as follow; 94% from power plants, 4% from biofuel and 2% from coal to liquid plants.

Social implications
Carbon capture and storage (CCS) is one practice aiming to reduce the amounts of anthropogenic emissions of carbon dioxide emitted into the atmosphere and reduce the related social costs. However, given the relatively high cost associated with this practice, coupling it with EOR could offer a significant financial incentive to facilitate the development of CCS projects and meet climate change objectives.

Originality/value
The model used in this study can be straightforwardly adapted to any geographic location where industry and policymakers are looking to simultaneously reduce CO2 emissions while increasing hydrocarbon recovery. The model is highly adaptable to local values in the parameters considered and to include additional local considerations such as geographic variation in capture costs, taxes and premiums to be placed on CO2 capture in so-called “non-attainment zones” where pollution capture make could make a project politically and economically viable. Regardless of how and where this model is applied, it is apparent that CO2 from industrial sources has substantial potential value as a coproduct that offsets its sequestration costs using existing, commercially available CO2-EOR technology, once sources and sinks are optimally paired.

PurposeInformation technology/software (IT/SW) professionals use the business model canvas (BMC) to identify innovative digital solutions that improve their client’s business values. This paper aims to address the issue of considering, for a client company, the status of its intangible assets (IAs) in decision-making on the most innovative digital solution.Design/methodology/approachThis paper provides a method (BMCIA-method) and a simulation tool (BMCIA-NetSim) to help IT/SW professionals identify and assess an organization’s IAs and their impact on the BMC of digital business.FindingsIT/SW professionals used this approach, at 14 small and medium-sized enterprises (SMEs), to identify innovative solutions and add digital value to their businesses. They used the BMCIA to provide their clients (SME’s chief executive officer or chief operating officer) with a view of the BMC enhanced with the status of IAs. These expressed interest in the use of the BMCIA and underscore its importance for making better decisions while aligning IT and the business. A survey reveals how well the BMCIA-method performed during its use to discover the best solution to be developed at each SME.Research limitations/implicationsIAs affect the achievement of the business goal targeted using the BMC. If these are not identified, valued and properly aligned with the BMC blocks, critical information is hidden from the eyes of IT/SW professionals and their clients, preventing optimal decision-making on which is the best IT/SW solution to be implemented to add digital value to the client company.Originality/valueThis proposal is unique insofar as it outlines a simulation-based methodological and technical solution using software agents to simulate the impact of the intangible side of an organization on its business model.

ObjectiveThis study aimed to conduct a randomised pilot trial to assess the feasibility of a randomised controlled trial (RCT) to investigate the effect of telephone-guided self-help for the treatment of mental health difficulties in children with neurological conditions.DesignPreliminary RCT. The primary outcome measure was the Strengths and Difficulties Questionnaire.SettingNeurology clinics in a national tertiary paediatric hospital.PatientsYoung people attending neurology clinics who met criteria for mental health difficulties according to the Development and Wellbeing Assessment.Interventions12 weeks of telephone-guided self-help based on a modular approach to psychological therapy for children delivered to children and/or their parents (n=17; eight males; mean age 12.04 years, SD=3.34) or a waiting list for telephone-guided self-help with no additional intervention over 12 weeks (n=17; nine males; mean age 10.53 years, SD=3.14).Results124 participants completed the DAWBA, and 34 children and young people were entered into the trial. 65% of those randomised to the intervention arm completed the full intervention, and the intervention was acceptable to those completing it. However, there were significant problems related to lack of data completion (38% data loss for primary outcome measure), choice of control comparator and outcome measures. Due to significant loss of data at follow-up, the effect size findings are considered unreliable.ConclusionsFurther feasibility work should be conducted to improve data completeness before progression to a definitive trial of guided self-help for mental health problems in children with neurological conditions can be recommended.Trial registration numberISRCTN21184717.
Determinants of physician networks: an ethnographic study examining the processes that inform patterns of collaboration and referral decision-making among physicians
Authors: Kierkegaard Patrick , Owen-Smith Jason 
Published: January 2021

ObjectiveMost scholarly attention to studying collaborative ties in physician networks has been devoted to quantitatively analysing large, complex datasets. While valuable, such studies can reduce the dynamic and contextual complexities of physician collaborations to numerical values. Qualitative research strategies can contribute to our understanding by addressing the gaps left by more quantitative approaches. This study seeks to contribute to the literature that applies network science approaches to the context of healthcare delivery. We use qualitative, observational and interview, methods to pursue an in-depth, micro-level approach to the deeply social and discursive processes that influence patterns of collaboration and referral decision-making in physician networks.DesignQualitative methodologies that paired ethnographic field observations, semistructured interviews and document analysis were used. An inductive thematic analysis approach was used to analyse, identify and describe patterns in those data.SettingThis study took place in a high-volume cardiovascular department at a major academic medical centre (AMC) located in the Midwest region of the USA.ParticipantsPurposive and snowballing sampling were used to recruit study participants for both the observational and face-to-face in-depth interview portions of the study. In total, 25 clinicians and 43 patients participated in this study.ResultsTwo primary thematic categories were identified: (1) circumstances for external engagement; and (2) clinical conditions for engagement. Thematic subcategories included community engagement, scientific engagement, reputational value, experiential information, professional identity, self-awareness of competence, multidisciplinary programmes and situational factors.ConclusionThis study adds new contextual knowledge about the mechanisms that characterise referral decision-making processes and how these impact the meaning of physician relationships, organisation of healthcare delivery and the knowledge and beliefs that physicians have about their colleagues. This study highlights the nuances that influence how new collaborative networks are formed and maintained by detailing how relationships among physicians develop and evolve over time.

AimsIn Danish patients with inflammatory rheumatic diseases to explore self-protection strategies and health behaviour including adherence to disease-modifying antirheumatic treatment (DMARD) during the initial phase of the COVID-19 pandemic and again after the reopening of the society started. Furthermore, to identify characteristics of patients with high levels of anxiety and self-isolation.MethodsPatients in routine care followed prospectively in the nationwide DANBIO registry were invited to answer an online questionnaire regarding disease activity and COVID-19 infection, behaviour in March and June 2020. Responses were linked to patient data in DANBIO. Characteristics potentially associated with anxiety, self-isolation and medication adherence (gender/age/diagnosis/education/work status/comorbidity/DMARD/smoking/EQ-5D/disease activity) were explored with multivariable logistic regression analyses.ResultsWe included 12 789 patients (8168 rheumatoid arthritis/2068 psoriatic arthritis/1758 axial spondyloarthritis/795 other) of whom 65% were women and 36% treated with biological DMARD. Self-reported COVID-19 prevalence was 0.3%. Patients reported that they were worried to get COVID-19 infection (March/June: 70%/45%) and self-isolated more than others of the same age (48%/38%). The fraction of patients who changed medication due to fear of COVID-19 were 4.1%/0.6%. Female gender, comorbidities, not working, lower education, biological treatment and poor European Quality of life, 5 dimensions were associated with both anxiety and self-isolation.ConclusionIn >12 000 patients with inflammatory arthritis, we found widespread anxiety and self-isolation, but high medication adherence, in the initial phase of the COVID-19 pandemic. This persisted during the gradual opening of society during the following months. Attention to patients’ anxiety and self-isolation is important during this and potential future epidemics.
Cosmology and the massive photon frequency shift in the Standard-Model Extension
Authors: Spallicci Alessandro D. A. M. , Helayël-Neto José A. , López-Corredoira Martín , Capozziello Salvatore 
Published: January 2021

AbstractThe total red shift z might be recast as a combination of the expansion red shift and a static shift due to the energy–momentum tensor non-conservation of a photon propagating through Electro-Magnetic (EM) fields. If massive, the photon may be described by the de Broglie–Proca (dBP) theory which satisfies the Lorentz(-Poincaré) Symmetry (LoSy) but not gauge-invariance. The latter is regained in the Standard-Model Extension (SME), associated with LoSy Violation (LSV) that naturally dresses photons of a mass. The non-conservation stems from the vacuum expectation value of the vector and tensor LSV fields. The final colour (red or blue) and size of the static shift depend on the orientations and strength of the LSV and EM multiple fields encountered along the path of the photon. Turning to cosmology, for a zero $$\Omega _{\Lambda }$$

Ω
Λ

energy density, the discrepancy between luminosity and red shift distances of SNeIa disappears thanks to the recasting of z. Massive photons induce an effective dark energy acting ‘optically’ but not dynamically.
From Flanders to Lisbon to the Mughal Empire: Hendrick Uwens and the Mathematical Backstage of a Jesuit Missionary’s Life
Authors: Castel-Branco Nuno 
Published: January 2021

Abstract
Hendrick Uwens (1618-1667) was a Flemish-educated Jesuit who became a missionary to the Mughal Empire. Prior to embarking on his missionary work, he taught mixed mathematics in Lisbon in the early 1640s. Both in Europe and India, Uwens often insisted on portraying himself as a mathematician. Mathematics allowed him to be amongst the first teachers of certain aspects of Galileo’s physics and to promote a mechanical worldview – unusual ideas in early Jesuit circles. He also used mathematics to negotiate his missionary appointments in Asia. This paper analyzes the manuscript writings produced by Uwens throughout his life: the letters he wrote in Flanders to the Superior General requesting to be made a missionary, his Portuguese textbook on mechanics, and his correspondence from India to his Jesuit Superiors in Flanders and Rome.
The Case of Albanian as an Islamic Language between Muslim Literary Tradition and National Culture
Authors: Bria Gianfranco 
Published: January 2021

Abstract
This paper aims to apply Bausani’s notion of “Islamic language” to the case of the Albanian language, analysing the cultural and linguistic evolution of its literature according to the various stages of the nation-building process, which concerned also the creation (re-invention) of a standard alphabet. To do so, this work firstly examines the literary production of Albanian Muslim writers during the Ottoman period and then analyses the gradual literary de-Islamisation that invested Albanian culture from the period of Rilindja (Rebirth) until the cultural revolution of the Communist atheist regime.
Suicide in Homer and the Tale of the Heike
Authors: Yamagata Naoko 
Published: January 2021

Abstract
Comparison of suicides and suicidal wishes in Homer and the Tale of the Heike reveals significant similarities. In both worlds, shame, loyalty, and grief are the main causes of suicidal wishes. However, Heike characters are more prone to suicide, while Homeric characters never actually commit suicide. Heike suicides can be seen to derive from the desire to be with one’s community and loved ones, enhanced by the Buddhist belief in an afterlife. Homeric characters display much stronger attachment to life, based on the belief that there is no existence or fame after death worth dying for.
Mechanism for the Formation of Arc-Shaped Cloud Lines over the Tropical Oceans
Authors: Stephan Claudia Christine 
Published: January 2021

AbstractSatellite images frequently show mesoscale arc-shaped cloud lines with a spacing of several tens of kilometers. These clouds form in a shallow mixed boundary layer in locations where the near-surface horizontal wind speed exceeds ~7 m s−1. Unlike other mesoscale cloud line phenomena, such as horizontal convective rolls, these cloud lines do not align with the wind direction but form at large oblique angles to the near-surface wind. A particularly distinct event of this pattern developed on 31 January 2020 over the western tropical Atlantic Ocean. Radiosonde soundings are available for this time and location, allowing a detailed analysis. By comparing observations with theoretical predictions that are based on Jeffreys’s drag-instability mechanism, it is shown that drag-instability waves may contribute to the formation of this cloud pattern. The theory is formulated in only two dimensions and predicts that wavelike horizontal wind perturbations of this wavelength can grow, because they modulate the surface friction in a way that reinforces the perturbations. The theoretical horizontal wavelengths of 40–80 km agree with the observations. Streamlines from the ERA5 reanalysis show that the directional change of the near-surface wind is likely to contribute to the arc shape but that a radial propagation of an initial instability is also required to explain the strong curvature. Moreover, ERA5 winds suggest that other known explanations for the formation of cloud lines are unlikely to apply in the case studied here.
Measuring Changes in Snowpack SWE Continuously on a Landscape Scale Using Lake Water Pressure
Authors: Pritchard Hamish D. , Farinotti Daniel , Colwell Steven 
Published: January 2021

AbstractThe seasonal snowpack is a globally important water resource that is notoriously difficult to measure. Existing instruments make measurements of falling or accumulating snow water equivalent (SWE) that are susceptible to bias, and most represent only a point in the landscape. Furthermore, the global array of SWE sensors is too sparse and too poorly distributed adequately to constrain snow in weather and climate models. We present a new approach to monitoring snowpack SWE from time series of lake water pressure. We tested our method in the lowland Finnish Arctic and in an alpine valley and high-mountain cirque in Switzerland and found that we could measure changes in SWE and their uncertainty through snowfalls with little bias and with an uncertainty comparable to or better than that achievable by other instruments. More importantly, our method inherently senses change over the whole lake surface, an area in this study up to 10.95 km2, or 274 million times larger than the nearest pluviometer. This large scale makes our measurements directly comparable to the grid cells of weather and climate models. We find, for example, snowfall biases of up to 100% in operational forecast models AROME-Arctic and COSMO-1. Seasonally frozen lakes are widely distributed at high latitudes and are particularly common in mountain ranges, hence our new method is particularly well suited to the widespread, autonomous monitoring of snow-water resources in remote areas that are largely unmonitored today. This is potentially transformative in reducing uncertainty in regional precipitation and runoff in seasonally cold climates.
Analysis of the effect of percutaneous vertebroplasty in the treatment of thoracolumbar Kümmell’s disease with or without bone cement leakage
Authors: Xiao Ya-Ping , Bei Ming-Jian , Yan Cui-Qing , Chang Jian-Zhong 
Published: January 2021

Abstract
Background
Bone cement leakage is a major complication in the treatment of percutaneous vertebroplasty for Kümmell’s disease, and the focus of close attention during the surgery. The purpose of this article was to investigate the clinical outcomes of Kümmell’s disease treated by percutaneous vertebroplasty with or without bone cement leakage.

Methods
A total of 64 patients with Kümmell’s disease from December 2016 to February 2018 treated by percutaneous vertebroplasty were included in the study. After the treatment, 32 cases were respectively divided into two groups according to X-ray examination of bone cement leakage: leakage group and non-leakage group. Preoperative course, age, sex, bone mineral density, damaged segment, anterior vertebral height, vertebral compression rate, Cobb angle, visual analogue scale and Oswestry dysfunction index were compared between the two groups. After surgery, the amount of bone cement injected, operation time, adjacent vertebral refracture rate, visual analogue scale, Oswestry dysfunction index, the recovery value of vertebral anterior height and the improvement value of Cobb angle were compared between the two groups.

Results
The course, age and Cobb angle of the leakage group were significantly greater than those of the non-leakage group (P< 0.05, respectively). The height of anterior vertebral margin and bone mineral density in the leakage group were significantly lower than those in the non-leakage group (P< 0.05, respectively). The two groups were followed up for at least 24 months. The amount of bone cement injected was significantly greater in the leakage group than in the non-leakage group (P=0.000). Visual analogue scale and Oswestry dysfunction index of the two groups on the second day after surgery and at the last follow-up were significantly lower than these before surgery (P< 0.05, respectively), but there was no significant difference between the two groups. In the leakage group, the recovery value of the anterior edge height of the injured vertebra and the improvement value of the Cobb angle on the second day after surgery and at the last follow-up were significantly improved compared with the non-leakage group (P< 0.05, respectively).

Conclusion
Percutaneous vertebroplasty is an effective and minimally invasive treatment for Kümmell’s disease. The leakage group had longer course, older age, more serious kyphotic deformity, vertebral compression and osteoporosis, and higher amount of bone cement injected than these of the non-leakage group. However, there were not significant differences in the rate of adjacent vertebral refractures, visual analogue scale and Oswestry dysfunction index between the two groups. Therefore, the bone cement leakage does not affect the surgical effect.

AbstractPrevost et al. published a systematic review evaluating the use of manual therapy for clinical conditions in the pediatric population in 2019. However, several methodological flaws in the conduct of the review limit the internal validity of its conclusions. We caution readers about the validity of the recommendations and suggest that the review not be used to inform the clinical management of pediatric patients.
