Intangible Resources Management and Sustainability of Selected Manufacturing Organizations in Nigeria
Authors: Madu Ifeanyi Leo , Nnaeto Japhet Olusadum , Eyikorogha Queen
Published: February 2023

Organization managers have rarely recognized the link between intangibles and entrepreneurial activity, consequently many firms are unable to identify and evaluate the contributions of intangible resources management to organizational sustainability. This unparalleled significance of intangible resources in contemporary business world has made intangible resources management necessary. Presently, many organizations are yet to adopt this practice. Thus, there is need to develop strategies to match the new paradigm shift. To this end, the study sought to ascertain the impact of intangible resources management on the sustainability of manufacturing organization in Nigeria. The researchers adopted survey design. Data were collected by structured questionnaire in Likert’s five scale format. The sources of data were through primary and secondary sources. Sample size of 503 was derived from the application of Cochran’s formula for finite population while Bowley’s proportional allocation method was adopted to determine the allocation of questionnaire to each organization. . A test-retest method was used to determine the reliability of questionnaire using Spearman’s Rank Order Correlation Coefficient. The result gave a reliability coefficient of 0.93. The two hypotheses were formulated and tested through Simple Linear Regression at 0.05 level of significance. The findings revealed that: firm’s resources and capabilities significantly enhanced competitive advantage (r = 0.895801; p <0.05). Employees’ competences had significant positive effect on organization’s image (r = 0.763; p <0.05). The study concluded that it in the present dispensation, the global business is no more dependent upon the tangible resources as such intangible resources imbedded in organization members are the enablers of other corporate resources and the base for sustained organizational viability. The study recommends that in this economic paradigm where sustainable competitive advantage is tangled to individual workers’ and organizational knowledge; there is need to develop strategies heavily on improving intangible resources imbedded in individuals to march the new situation that imposes new requirements on the management of manufacturing organizations.

Authors: Kolug Joseph Yenabil , Kankam Jnr George
Published: February 2023

The purpose of the study was to find out the key constructs of e-learning towards customer satisfaction of distance learning students in Ghana. Four hypotheses were formulated for the study. A cross-sectional survey design that adopted the quantitative research approach was used. A sample size of 420 was selected using convenient sampling. Data was analysed with SPSS. Spearman’s correlation and multiple regression analysis were used to analyze the hypotheses. The study revealed that course flexibility and learners’ interaction with others were the major factors that positively impacted customer satisfaction. Therefore, the study recommended that time schedules for online courses should be “rigid free” and not subjected to strict times which are unpleasant for learning and discussions. The study concluded that to continue enabling marginalized and disadvantaged students to access distance-learning education, policymakers need to hear the voices of distance-learning students on course flexibility and learners’ interactions.

Aphid is a major pest of wheat that causes substantial agricultural damages to wheat crop annually. In the present study, experiments on ecofriendly management of this pest were conducted at the experimental area of Arid Zone Research Institute (AZRI), Bhakkar. The trials were laid down in Randomized Complete Block Design (RCBD) with three replications. Data was collected at seven days interval by counting method. As far as efficiency of yellow sticky traps is concerned, the plot having 4-traps captured maximum (848.07) aphids. As a result, minimum (11.16 aphid tiller-1) were observed in the respective plot. The same plot exhibited maximum population reduction (71.93%) and grain yield (6617.9 kg ha-1). The plot having 1-trap captured minimum (257.33) aphids. Consequently, maximum (33.37 aphids/tiller) were found in the field. The same treatment showed minimum population reduction (23.99%) and grain yield (5489.1 kg ha-1). Chrysoperla carnea was found a voracious predator of the pest. The plot having 4-egg cards of this predator showed minimum (7.69 aphids tiller-1) with maximum (49.50%) population reduction of the aphid followed by 8.78 aphids/tiller in the plot having 3-egg cards with 42.56% population reduction. Lowest population reduction (12.33%) was found in the plot having 1 egg card.

Published: February 2023

The paper presents an analytical review of technological processes of alternative jet fuel production from alcohols and experimental results on the study of its physical-chemical properties. State-of-the-art in the sphere of civil aviation development within the framework of sustainable development and minimization of transport’s negative impact on the environment is presented. The development and implementation of sustainable aviation fuels are considered the main measure for reaching carbon-neutral growth. Two technologies of alcohol-to-jet fuel production are considered, and possible feedstock and processing pathways are presented. Physical-chemical properties of two kinds of alcohol-to-jet fuels are studied experimentally, as well as the properties of conventional jet fuels blended with alternative ones. It is shown that the physical-chemical properties of jet fuels blended with alcohol-to-jet component containing aromatics are very close to conventional jet fuels. All of the studied fuel blends with alcohol-to-jet components completely satisfy the requirements of specifications. Basing on the received results it is expected that alcohol-to-jet component containing aromatics may be successfully used for blending with conventional jet fuel and used as a drop-in fuel.
Two Candidates for Dual AGN in Dwarf-dwarf Galaxy Mergers
Authors: Mićić Marko , Holmes Olivia J. , Wells Brenna N. , Irwin Jimmy A.
Published: February 2023

Dual active galactic nuclei (DAGN) are important for understanding galaxy-merger-triggered fueling of black holes and the hierarchical growth of structures. The least explored type of DAGN are those associated with mergers of two dwarf galaxies. According to observations and cosmological simulations, dwarf galaxies are the most abundant type of galaxies in the early universe and the galaxy-merger rate is dominated by dwarfs. However, these mergers are generally too distant to be directly observed, and low-redshift dwarf-dwarf merger-related DAGN are notoriously hard to find. In this paper, we present the first results of our large-scale search for this elusive type of object and the first two candidates for DAGN in dwarf-dwarf mergers. Both objects exhibit tidal features (tails and bridges) characteristic of galaxy mergers/interactions. One object is apparently in a late-stage merger with an AGN separation of <5 kpc, while the second is in an early-stage merger with interacting galaxies having established a tidal bridge. Both objects have dual, luminous X-ray sources that are most likely due to actively accreting massive black holes. Also, both objects have infrared counterparts, with colors consistent with being AGN. Follow-up observations will provide us a glimpse into key processes that govern the earliest phases of growth of galaxies, their central black holes, and merger-induced star formation.
Magnetic Flux Transport in Radiatively Inefficient Accretion Flows and the Pathway toward a Magnetically Arrested Disk
Authors: Dhang Prasun , Bai Xue-Ning , White Christopher J.
Published: February 2023

Large-scale magnetic fields play a vital role in determining the angular momentum transport and generating jets/outflows in accreting systems, yet their origins remain poorly understood. We focus on radiatively inefficient accretion flows (RIAFs) around black holes (BHs), and conduct 3D general-relativistic magnetohydrodynamic simulations using the Athena++ code. We first reconfirm that the magnetorotational instability driven dynamo in the RIAF alone does not spontaneously form a magnetically arrested disk (MAD), conducive for strong-jet formation. We next investigate the other possibility, where the large-scale magnetic fields are advected inward from external sources (e.g., the companion star in X-ray binaries and the magnetized ambient medium in active galactic nuclei). Although the actual configurations of the external fields could be complex and uncertain, they are likely to be closed. As a first study, we treat them as closed field loops of different sizes, shapes, and field strengths. Unlike earlier studies of flux transport, where the magnetic flux is injected into the initial laminar flow, we inject the magnetic field loops into the quasi-stationary turbulent RIAF in inflow equilibrium, then follow their evolution. We find that a substantial fraction (∼15%–40%) of the flux injected at large radii reaches the BH, with a weak dependence on the loop parameters, except when the loops are injected at high latitudes, away from the midplane. The relatively high efficiency of the flux transport observed in our study hints that a MAD might easily be formed relatively close to the BH, provided that a source of the large-scale field exists at larger radii.
On the Connection between Rieger-type and Magneto-Rossby Waves Driving the Frequency of the Large Solar Eruptions during Solar Cycles 19–25

Global solar activity variation mainly occurs over about an 11 yr cycle. However, both longer and shorter periodicities than the solar cycle are also present in many different solar activity indices. The longer timescales may be up to hundreds of years, while the shorter timescales for global solar variability could be within 0.5–2 yr, which include, e.g., from the Rieger-type periods (150–160 days) to quasi-biennial oscillations of 2 yr. The most likely origin of this short-timescale quasi-periodicity is attributed to magnetic Rossby waves, which have periods of 0.8–2.4 yr. In this work, we present findings of a unique evolution of identified shorter periodicities, like the Rieger-type, arising from magnetic Rossby waves, throughout Solar Cycles 19–25. We report further observational evidence of the strong relationship between the Rieger-type periodicity, magneto-Rossby waves, and major solar flare activity. Moreover, this study also reveals that the global solar magnetic field has a continuous periodic longitudinal conveyor belt motion along the solar equator, together with an up-and-down movement in the latitudinal directions. We found that when these longitudinal and latitudinal movements have Rieger-type periodicity and magneto-Rossby waves during the same period of a solar cycle, major flare activity is present.

Published: February 2023

Gamma-ray bursts (GRBs) have been considered as potential very high energy photon emitters due to the large amount of energy released as well as the strong magnetic fields involved in their jets. However, the detection of teraelectronvolt photons is not expected from bursts beyond a redshift of z ≳ 0.1, due to their attenuation with the extragalactic background light (EBL). For these reasons, the recent observation of photons with energies of 18 and 251 TeV from GRB 221009A (z = 0.151) last 2022 October 9 has challenged what we know about the teraelectronvolt-emission mechanisms and the extragalactic background. In order to explain the teraelectronvolt observations, recent works exploring candidates of dark matter have started to appear. In this paper, we discuss the required conditions and limitations within the most plausible scenario, synchrotron self-Compton radiation in the GRB afterglow, to interpret the one 18 TeV photon observation besides the EBL. To avoid the Klein–Nishina effect, we find an improbable value of the microphysical magnetic parameter below 10−6 for a circumburst medium value >1 cm−3 (expected in the collapsar scenario). Therefore, we explore possible scenarios in terms of axion-like particles (ALPs) and dark photon mechanisms to interpret this highly energetic photon and we discuss the implications in the GRB energetics. We find that the ALPs and dark photon scenarios can explain the 18 teraelectronvolt photon but not the 251 teraelectronvolt photon.
The Similar Seven: A Set of Very Alike Exoplanets to Test Correlations between System Parameters and Atmospheric Properties
Authors: McGruder Chima D. , López-Morales Mercedes , Brahm Rafael , Jordán Andrés
Published: February 2023

Studies of exoplanetary atmospheres have found no definite correlations between observed high-altitude aerosols and other system parameters. This could be, in part, because of the lack of homogeneous exoplanet samples for which specific parameters can be isolated and inspected. Here, we present a set of seven exoplanets with very similar system parameters. We analyze existing photometric time series, Gaia parallax, and high-resolution spectroscopic data to produce a new set of homogeneous stellar, planetary, and orbital parameters for these systems. With this, we confirm that most measured parameters for all systems are very similar, except for the host stars’ metallicities and possibly high-energy irradiation levels, which require UV and X-ray observations to constrain. From the sample, WASP-6b, WASP-96b, and WASP-110b have observed transmission spectra that we use to estimate their aerosol coverage levels using the Na i doublet 5892.9 Å. We find a tentative correlation between the metallicity of the host stars and the planetary aerosol levels. The trend we find with stellar metallicity can be tested by observing transmission spectra of the remaining planets in the sample. Based on our prediction, WASP-25b and WASP-55b should have higher levels of aerosols than WASP-124b and HATS-29b. Finally, we highlight how targeted surveys of alike planets similar to the ones presented here might prove key for identifying driving factors for atmospheric properties of exoplanets in the future and could be used as a sample selection criterion for future observations with, e.g., JWST, ARIEL, and the next generation of ground-based telescopes.

Gamma-ray bursts (GRBs) are the most powerful explosions in the universe. How efficiently the jet converts its energy to radiation is a long-standing problem, which is poorly constrained. The standard model invokes a relativistic fireball with a bright photosphere emission component. A definitive diagnosis of GRB radiation components and the measurement of GRB radiative efficiency require prompt emission and afterglow data, with high resolution and wide band coverage in time and energy. Here, we present a comprehensive temporal and spectral analysis of the TeV-emitting bright GRB 190114C. Its fluence is one of the highest for all the GRBs that have been detected so far, which allows us to perform a high-resolution study of the prompt emission spectral properties and their temporal evolutions, down to a timescale of about 0.1 s. We observe that each of the initial pulses has a thermal component contributing ∼20% of the total energy and that the corresponding temperature and inferred Lorentz factor of the photosphere evolve following broken power-law shapes. From the observation of the nonthermal spectra and the light curve, the onset of the afterglow corresponding to the deceleration of the fireball is considered to start at ∼6 s. By incorporating the thermal and nonthermal observations, as well as the photosphere and synchrotron radiative mechanisms, we can directly derive the fireball energy budget with little dependence on hypothetical parameters, measuring a ∼16% radiative efficiency for this GRB. With the fireball energy budget derived, the afterglow microphysics parameters can also be constrained directly from the data.

Published: February 2023

BACKGROUND: Gold mining, especially by the community, causes many problems. One of the problems is the increase in mercury pollution. The amalgamation technique involving mercury in the gold processing process is still widely used by miners and has the potential to threaten the health of workers and the surrounding community.
AIM: This study aimed to identify mercury levels in soot at the location of a traditional gold processing plant in Paya Seumantok Village, Krueng Sabee District, Aceh Jaya District.
METHODS: This research was conducted at the Environmental Quality Analysis laboratory, Chemical Engineering Department, Syiah Kuala University, Banda Aceh, in May–August 2021. The sample in this study was soot caught on cloth attached to the gold kiln location by amalgamation using the quadrant method. The soot sample was obtained from the people’s gold processing unit in Gampong Paya Seumantok, Krueng Seabee District; then, the fabric sample containing soot was destroyed using HNO3 in the microwave. Measurement of mercury levels, using AAS Perkin-Elmer Analyst 600, equipped with Graphite Furnace (AAS) Technique.
RESULTS: The results of the identification show that the mercury level in the first stage of measurement found the highest mercury concentration at a distance of 10 cm with a concentration of 41.90 (±21.64) g-Hg/g, a distance of 5 cm was obtained at 28.71 (±11. 0.98) g-Hg/g, and at a distance of 15 cm obtained 28.20 (±2.85) g-Hg/g. Furthermore, in the measurement of samples in stages 2 and 3, the mercury concentration in soot is influenced by distance, where the closer the distance, the higher the mercury concentration. Stage 2 measurement at a distance of 5 cm, the mercury concentration obtained is 26.84 (±21.05) g-Hg/g, a distance of 10 and 15 cm each has a concentration of 9.25 (±1.26) g-Hg/g and 9.91 (±3.59) g-Hg/g, and in the third stage of the test, the highest concentration located at a distance of 5 cm with a concentration of 20.27 (±3.57) g-Hg/g.
CONCLUSION: The average value of mercury concentration in soot obtained far exceeds the threshold set by the World Health Organization, which is 1 g-Hg/gram. Mercury levels that have exceeded the threshold need to be filtered in an enclosed space before the smoke from burning gold spreads into the free air.

Published: February 2023

The impact of the COVID-19 pandemic highlighted health inequities for people with intellectual and developmental disability (PWIDD). It was also the stimulus for an international group of nurse researchers with shared expertise and experience to create a Global IDD Nursing Collaboratory. A collaboratory is a networked environment or “center without walls” where interaction oriented to common research areas occur without regard to physical location. The overarching goal of this Global Nursing Collaboratory is to assure the highest quality of life for PWIDD across the lifespan. Applying their unique skills and expertise, nurses working across health and social contexts are often the bridge over the healthcare gaps encountered by PWIDD. This paper describes the potential practice, education, and research contributions nurses can make to reduce health inequities experienced by PWIDD. We will examine how we talk about disability, the impact of the current COVID 19 crisis, and our educational systems which in some countries leave nurses and other health professionals ill prepared to meet the unique needs of this population We will describe the context, access issues, and health service organizations for and with PWIDD across countries to equip nurses with basic knowledge of health care for PWIDD and energize meaningful improvement in delivery of this care. Importantly, we offer action steps for all nurses toward reducing stigma and health inequities related to living with an intellectual and developmental disability (IDD).
La santé comme domaine du développement : un panorama historico-critique
Authors: Ridde Valery , Boidin Bruno
Published: February 2023

Cet entretien analyse la façon dont la thématique de la santé a été abordée dans la revue Mondes en développement et propose une perspective critique des modèles dominants de l’aide dans le domaine de la santé. Au regard des quarante dernières années, la permanence de certaines idées, malgré leur caractère discutable, est mise en évidence. Les échecs des paradigmes dominants et des dispositifs associés n’ont pas débouché sur de véritables réorientations des politiques de santé. Derrière cette réalité sont mis au jour des intérêts stratégiques du côté des experts et des institutions. Pourtant, quelques perspectives se dégagent à travers les expériences de terrain innovantes et l’évaluation réaliste des leviers de réussite et des obstacles rencontrés par les programmes.

Introduction

Published: February 2023

Ce dossier propose à partir de plusieurs études (Antilles, La Réunion, Pacifique) une écriture de l’histoire des départementalisations et des évolutions ultramarines « de l’uniformité à la différenciation ». Les articles interrogent les contextes politiques et les mises en œuvre de cette réforme fondatrice, acte fondateur voté par la première Assemblée Constituante (19 mars 1946). À partir des analyses de cette « décolonisation intra-française », les textes soulignent le fossé qui se creuse sous la IV e  République entre les attentes teintées d’impatience exprimées localement à l’aune des espoirs suscités et l’absence de concrétisation des objectifs d’égalité sociale. Ce dossier démontre combien les débats sur les départementalisations et les devenirs institutionnels résonnent et demeurent présents dans l’histoire du temps présent des outre-mer français.
Réévaluer la départementalisation des vieilles colonies à l’aune de ses réticences étatiques : le cas des Antilles (1944-1947)
Authors: Mary Sylvain
Published: February 2023

Cet article propose de réévaluer la départementalisation des vieilles colonies des Antilles (Guadeloupe, Martinique) à travers le contexte global de réforme de l’empire entre 1944 et 1947. Il montre que le consensus d’après-guerre quant à l’extension du statut départemental aux vieilles colonies, ne saurait occulter les divergences de conception séparant les promoteurs ultramarins de la réforme et le gouvernement quant à la portée de ce changement statutaire en termes d’égalité avec la métropole. Les réticences étatiques à envisager une départementalisation calquée sur les standards métropolitains portent en germes les désillusions observées aux Antilles vers la fin des années 1940 au sujet de cette mutation statutaire pourtant tant attendue.

Le Bureau des Affaires musulmanes, créé en 1906 et devenu Service des Affaires musulmanes à partir de 1912 – sous la direction de Paul Marty –, a développé différentes stratégies pour surveiller les acteurs de l’islam. Les documents d’identité, tels que le laissez-passer et le passeport, ont ainsi été mobilisés pour contrôler les mobilités internes et externes à l’Afrique Occidentale Française (AOF). L’obtention ou le refus d’octroi du laissez-passer à un marabout ou du passeport à un étudiant d’AOF à Al-Azhar intervenaient au terme d’une enquête – menée par le commandant de cercle et ses collaborateurs – dont les résultats sont consignés dans une fiche de renseignements. Cet article interroge le lien que le gouvernement colonial français a établi entre la fiche de renseignements et les documents d’identité des acteurs de l’islam. Le papier considère ces documents comme un dispositif de politique musulmane traduisant des hésitations, des options du moment, des préjugés, voire des obsessions collectives qui s’emparent d’une période à l’autre de l’administration française en Afrique de l’Ouest.

Published: February 2023

In this paper, we consider the solution of linear weighted complementarity problem (denoted by LWCP). Firstly, we introduce a new class of weighted complementary functions and show that its continuously differentiable. On this basis, the LWCP is reconstructed as a smooth system of equations, and then solved by the Levenberg-Marquardt method. The convergence of the algorithm is proved theoretically and numerical experiments are carried out. The comparative experiments show that the algorithm has some advantages in computing time and iteration times.

Recycled concrete aggregates (RCAs) have been demonstrated as an alternative source to exhaustible natural aggregates. In this paper, we focus on the enhancement treatments for coarse and fine RCAs and the effect of these treatments on the durability of recycled concrete (RC) made from treated RCAs by the weakening and strengthening of the cement paste adhered to their surface. We conducted comparative analyses on the improvement of durability and mechanical properties. The results showed that the reduction of water absorption in RCAs increases the compressive strength of RC and that there is a strong linear trend of improvement in the carbonation depth, chloride ion penetration, and compressive strength of RC. For fine and coarse RCAs, the treatment mechanism and particle size are determinants in efficiently improving RC durability.

The purpose of this research article was to contrast the benefits of the optimal probability threshold adjustment technique with other imbalanced data processing techniques, in its application to the prediction of post-graduate students’ late dropout from distance learning courses in two universities in the Ibero-American space. In this context, the optimization of the Logistic Regression, Random Forest, and Neural Network classifiers, together with different techniques, attributes, and algorithms (Hyperparameters, SMOTE, SMOTE_SVM, and ADASYN) resulted in a set of metrics for decision-making, prioritizing the reduction of false negatives. The best model was the Neural Network model in combination with SMOTE_SVM, obtaining a recall index of 0.75 and an f1-Score of 0.60. Likewise, the robustness of the Random Forest classifier for imbalanced data was demonstrated by achieving, with an optimal threshold of 0.427, very similar metrics to those obtained by the consensus of the three best models found. This demonstrates that, for Random Forest, the optimal prediction probability threshold is an excellent alternative to resampling techniques with different optimal thresholds. Finally, it is hoped that this research paper will contribute to boost the application of this simple but powerful technique, which is highly underrated with respect to data resampling techniques for imbalanced data.
Designing Learning Activities in Minecraft for Formal Education in Geography

Digital technology has shaped the way humans interact with information and create knowledge. These conditions have in turn shaped a generation of people who experienced virtual environments very early in their lives and are often referred to as digital natives. This group of people has a particular way of communicating and interacting. It characterizes their affinity spaces and the many experiences with virtual worlds and digital games. In digital games, the separation between entertainment and learning is becoming less pronounced. Many game titles have been used for educational purposes. An iconic example is Minecraft, which has been used formally in some schools to teach topics on the environment. However, studies on formal topics in Geography are conspicuously absent, and we therefore selected Minecraft to understand how digital natives learn about Geography given the character of its virtual environment. To this aim, we developed a learning task scenario for global climate zones. The scenario was tested in two pilot studies with two different groups of participants. The results indicate that participants already share some degree of knowledge about the game environment, despite differences within the digital native group. Using the results of several pilot studies, we discuss the design choices to engage players in the game’s learning activity.

Fake accounts on online social networks are increasing today with an increase in the number of active social network users. Social media websites allow users to share thoughts, facts, views and re-sharing these into various networks. Social media platforms provide users with enormous valuable information but with this great amount of information in social media, many issues like fake profile, online hacking have also grown. The fake profiles in online social sites create fake news and share unwanted material which contains spam links that affect natural users. The massive issue in social media communication networks is spam and it is necessary to identify fake profiles to stop spam. In this paper, a supervised machine learning algorithm called support vector machine (SVM) is used to identify fake accounts on social media effectively. In order to automatically identify fake online profiles, Random Forest classifier is used with SVM. With this concept, it can be applied online easily to identify millions of accounts that cannot be examined manually. The result of this model is compared with other identification techniques and the results show that the proposed algorithm performs better with high precision and recall. This method efficiently safeguards social media networks from online threats and attacks.

Skin lymphomas are less common and subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a fairly rare subtype of primary cutaneous lymphoma. Skin lymphomas involve subcutaneous adipose tissues with no involvement of lymph nodes. Diagnosis of these cases is generally a challenge to clinicians. These cases present with fever, weight loss, and local discomfort in the region of involvement of subcutaneous tissues and sometime with skin eczema and rashes. Positron emission tomography/computed tomography (PET/CT) scan can guide in determining the extent of involvement being whole-body imaging and can guide the site of biopsy and can help to prevent misdiagnosis. It also helps in correct and early diagnosis and successful treatment. We report a case of a young adult who presented with pyrexia of unknown origin in which PET/CT scan revealed mildly fluorodeoxyglucose-avid diffuse subcutaneous panniculitis involving the whole body, trunk, and extremities. Biopsy was taken from the most appropriate site according to the PET/CT scan report and reported as SPTCL.

Background:

Transthoracic echocardiographic (TTE) estimation of the pulmonary to systemic flow ratio (Qp/Qs) is routinely used in clinical practice and is included in the American Society of Echocardiography Guidelines. We sought to assess its real-world applicability with a particular focus on hemodynamically significant shunt lesions.

Methods:

Retrospective single institutional review of TTE's in patients with secundum atrial septal defect prior to cardiac catheterization (cath) from 2012 to 2018 was performed (n = 109), those with technically limited images for Qp/Qs calculation (n = 11) and those with time interval between TTE and cath >60 days were excluded (n = 14). Qp/Qs was calculated from stored clips by previously described methods and correlated with those obtained by oximetry. Patients were subdivided into two age groups <21 (Group 1) and ≥22 years (Group 2). TTE and cath methods for Qp/Qs estimation were compared using paired t-test, Pearson's correlation coefficient, and Bland–Altman plots.

Results:

Eighty-four subjects met inclusion criteria (age range 3–78 years). Group 1 n = 35; median age 10 years; Group 2 n = 49; median age 49 years. Transthoracic echocardiogram was performed 19.5 ± 15 days prior to cath. Mean Qp/Qs derived by cath and TTE were 2.09 ± 0.9 versus 2.54 ± 1.2 (P < 0.0001). Overall correlation was poor between the methods (r
2 = 0.32, P < 0.0001) and continued to be poor for Groups 1 and 2 (r
2= 0.24, P = 0.003 and r
2= 0.40, P < 0.0001 respectively). Bland–Altman plots demonstrated poor agreement between the predetermined limits of agreement (-0.5–1.5).

Conclusion:

Transthoracic echocardiography estimated Qp/Qs, although routinely utilized in clinical practice, has poor correlation and agreement with oximetry-derived Qp/Qs. The test performs poorly in all age groups in detecting a hemodynamically significant shunt and tends to overestimate the degree of left to right shunt.
