Vituperative and Incendiary Language in Public Space a Ghanaian Social Concern
Authors: Boateng Edwin , Owiredu Yankah Priscilla
Published: March 2022

This paper projects the phenomenon of outbursts, insults, inflammatory and foul-language use in the public space and its implications on the moral fabric of the Ghanaian society. The objective is to sensitize the public of this negative development in the hope to encourage the use of decent language in the public space. It gives a background to the use of language in society as a normative practice in all societies and the legal implications of language use in public space in modern society. Furthermore, it throws light on the theory of ethical language, focusing on four approaches that facilitate understanding and meaning of ethical sentences. The use of language in the public space has been reviewed referencing existing literature and various case studies in different locations in contemporary times as a background to the paper. Methodological issues factored purposefully sampled views of two-hundred and nineteen respondents drawn from university campuses and the general public, in Kumasi and Accra. Research design essentialized mixed methods, integrating the explorative, qualitative and interpretive tools. Views were elicited through the tool of a survey questionnaire supported by field and library data. Data display, reduction, mapping and verified conclusion served as indices of analysis. Findings include the general awareness of worsening foul language use with incendiary and vituperative undertones in the Ghanaian public space and unanimity in the call for multisectoral and synergistic effort to salvage the situation as a matter of urgency.

TEMPORAL AND SPATIAL EVOLUTION CHARACTERISTICS OF LAND USE AND LANDSCAPE PATTERN IN KEY WETLAND AREAS OF THE WEST LIAO RIVER BASIN, NORTHEAST CHINA
Authors: Wang Zhichun , Zhao Huiying , Zhao Chunliang
Published: March 2022

The impact of the wetland ecosystem on arid and semi-arid areas is much higher than that in humid areas. It plays a more significant role in regulating climate, conserving water sources, purifying water bodies, and protecting biodiversity. The West Liao River Basin is located in a moderately temperate, semi-arid, and continental monsoon climatesensitive area, with a fragile ecological environment. Climate warming and drought have gradually caused dry-flow of some river sections in the basin, reduction in the water area, shrinking of wetlands, degradation of vegetation ecological function, and decline of biodiversity. Ultimately, the effect of ecological barriers is significantly weakened. The research of the temporal and spatial evolution of landscape patterns and their relationship with human activities in arid and semi-arid regions is of great significance for the protection and restoration of wetland resources. Based on Landsat remote sensing images in 1985 and 2015, the temporal and spatial evolution of landscape patterns in four key wetland areas in the West Liao River Basin was studied by 3S technology and landscape ecology indexes. Results show that during the 30a years, the wetland resources area in the West Liao River Basin is drastically reduced. Wetland resources of the four study areas, the Dalinor, the Saihanwula, the Hongshan Reservoir, and the West Liao River Estuary, were decreased by 13.80%, 31.06%, 61.10%, and 66.03%, respectively. The reduced wetland resources in the Dalinor and the Saihanwula were mainly converted into grassland, while those of the Hongshan Reservoir and the West Liao River Estuary were mostly converted into farmland. The diversity and evenness indexes of landscape in the Hongshan Reservoir and the West Liao River Estuary are gradually decreasing. The diversity and evenness indexes of the Dalinor and the Saihanwula are not significantly changed but are slightly disturbed by human activities. Changes in the landscape pattern index highlight the decrease in the water area, the increase in the area of dry and paddy fields, and the improvement of sandy land. All these further reflect that insufficient water resources supplementation and increasing human disturbance have a profound impact on the landscape pattern, which has also become the main driving force for the evolution of the landscape pattern in the West Liao River Basin.
Validation and Improvement of the Pan-STARRS Photometric Calibration with the Stellar Color Regression Method
Authors: Xiao Kai , Yuan Haibo
Published: March 2022

As one of the best ground-based photometric data set, Pan-STARRS1 (PS1) has been widely used as the reference to calibrate other surveys. In this work, we present an independent validation and recalibration of the PS1 photometry using spectroscopic data from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) DR7, and photometric data from the corrected Gaia Early Data Release 3 (EDR3) with the Stellar Color Regression (SCR) method. Using per band typically a total of 1.5 million LAMOST-PS1-Gaia stars as standards, we show that the PS1 photometric calibration precisions in the grizy filters are around 4 ∼ 5 mmag when averaged over 20′ regions. However, significant large- and small-scale spatial variation of magnitude offset, up to over 1%, probably caused by the calibration errors in the PS1, are found for all the grizy filters. The calibration errors in different filters are uncorrelated, and are slightly larger for the g and y filters. We also detect moderate magnitude-dependent errors (0.005, 0.005, 0.005, 0.004, 0.003 mag per magnitude in the 14–17 mag range for the grizy filters, respectively) in the PS1 photometry by comparing with the Gaia EDR3 and other catalogs. The errors are likely caused by the systematic uncertainties in the PSF magnitudes. We provide two-dimensional maps to correct for such magnitude offsets in the LAMOST footprint at different spatial resolutions from 20′ to 160′. The results demonstrate the power of the SCR method in improving the calibration precision of wide-field surveys when combined with the LAMOST spectroscopy and Gaia photometry.
Five Decades of Chromospheric Activity in 59 Sun-like Stars and New Maunder Minimum Candidate HD 166620
Authors: Baum Anna C. , Wright Jason T. , Luhn Jacob K. , Isaacson Howard
Published: March 2022

We present five decades of chromospheric activity measurements in 59 Sun-like stars as time series. These include and extend the 35 yr of stellar chromospheric activity observations by the Mount Wilson Survey (1966–2001), and continued observations at Keck by the California Planet Search (1996–). The Mount Wilson Survey was studied closely in 1995, and revealed periodic activity cycles similar to the Sun’s 11 yr cycle. The California Planet Search provides more than five decades of measurements, significantly improving our understanding of these stars’ activity behavior. We have curated the activity measurements in order to create contiguous time series, and have classified the stellar sample according to a predetermined system. We have analyzed 29 stars with periodic cycles using the Lomb–Scargle periodogram, and present best-fit sinusoids to their activity time series. We report the best-fit periods for each cycling star, along with stellar parameters (T
eff, log(g), vsin(i), etc.) for the entire sample. As a first application of these data, we offer a possible Maunder minimum candidate, HD 166620.
A New Planet Candidate Detected in a Dust Gap of the Disk around HD 163296 through Localized Kinematic Signatures: An Observational Validation of the discminer
Authors: Izquierdo Andrés F. , Facchini Stefano , Rosotti Giovanni P. , van Dishoeck Ewine F. , Testi Leonardo
Published: March 2022

We report the robust detection of coherent, localized deviations from Keplerian rotation possibly associated with the presence of two giant planets embedded in the disk around HD 163296. The analysis is performed using the discminer channel map modeling framework on 12CO J = 2–1 DSHARP data. Not only orbital radius but also azimuth of the planets are retrieved by our technique. One of the candidate planets, detected at R = 94 ± 6 au, ϕ = 50° ± 3° (P94), is near the center of one of the gaps in dust continuum emission and is consistent with a planet mass of 1 M
Jup. The other planet, located at R = 261 ± 4 au, ϕ = 57° ± 1° (P261), is in the region where a velocity kink was previously observed in 12CO channel maps. Also, we provide a simultaneous description of the height and temperature of the upper and lower emitting surfaces of the disk and propose the line width as a solid observable to track gas substructure. Using azimuthally averaged line width profiles, we detect gas gaps at R = 38, 88, and 136 au, closely matching the location of their dust and kinematical counterparts. Furthermore, we observe strong azimuthal asymmetries in line widths around the gas gap at R = 88 au, possibly linked to turbulent motions driven by the P94 planet. Our results confirm that the discminer is capable of finding localized, otherwise unseen velocity perturbations thanks to its robust statistical framework, but also that it is well suited for studies of the gas properties and vertical structure of protoplanetary disks.

The presence of complex organic molecules (COMs) in the interstellar medium is of great interest since it may link to the origin and prevalence of life in the universe. Aiming to investigate the occurrence of COMs and their possible origins, we conducted a chemical census toward a sample of protostellar cores as part of the Atacama Large Millimeter/submillimeter Array Survey of Orion Planck Galactic Cold Clumps project. We report the detection of 11 hot corino sources, which exhibit compact emissions from warm and abundant COMs, among 56 Class 0/I protostellar cores. All of the hot corino sources discovered are likely Class 0, and their sizes of the warm region (>100 K) are comparable to 100 au. The luminosity of the hot corino sources exhibits positive correlations with the total number of methanol and the extent of its emissions. Such correlations are consistent with the thermal desorption picture for the presence of hot corinos and suggest that the lower-luminosity (Class 0) sources likely have a smaller region with COM emissions. With the same sample selection method and detection criteria being applied, the detection rates of the warm methanol in the Orion cloud (15/37) and the Perseus cloud (28/50) are statistically similar when the cloud distances and the limited sample size are considered. Observing the same set of COM transitions will bring a more informative comparison between the cloud properties.
New Time-resolved, Multi-band Flares in the GJ 65 System with gPhoton

Published: March 2022

Characterizing the distribution of flare properties and occurrence rates is important for understanding habitability of M-dwarf exoplanets. The Galaxy Evolution Explorer (GALEX) space telescope observed the GJ 65 system, composed of the active, flaring M stars BL Cet and UV Cet, for 15,900 s (∼4.4 hr) in two ultraviolet (UV) bands. The contrast in flux between flares and the photospheres of cool stars is maximized at UV wavelengths, and GJ 65 is the brightest and nearest flaring M-dwarf system with significant GALEX coverage. It therefore represents the best opportunity to measure low-energy flares with GALEX. We construct high-cadence lightcurves from calibrated photon events and find 13 new flare events with near-UV (NUV) energies ranging from 1028.5–1029.5 erg and recover one previously reported flare with an energy of 1031 erg. The newly reported flares are among the smallest M-dwarf flares observed in the UV with sufficient time resolution to discern lightcurve morphology. The estimated flare frequency at these low energies is consistent with extrapolation from the distributions of higher-energy flares on active M dwarfs measured by other surveys. The largest flare in our sample is bright enough to exceed the local nonlinearity threshold of the GALEX detectors, which precludes color analysis. However, we detect quasi-periodic pulsations during this flare in both the far-UV and NUV bands at a period of ∼50 s, which we interpret as a modulation of the flare’s chromospheric thermal emission through periodic triggering of reconnection by external MHD oscillations in the corona.
Machine Learning Classification to Identify Catastrophic Outlier Photometric Redshift Estimates
Authors: Singal J. , Silverman G. , Jones E. , Do T. , Boscoe B. , Wan Y.
Published: March 2022

We present results of using a basic binary classification neural network model to identify likely catastrophic outlier photometric redshift estimates of individual galaxies, based only on the galaxies’ measured photometric band magnitude values. We find that a simple implementation of this classification can identify a significant fraction of galaxies with catastrophic outlier photometric redshift estimates while falsely categorizing only a much smaller fraction of non-outliers. These methods have the potential to reduce the errors introduced into science analyses by catastrophic outlier photometric redshift estimates.
Parallel Electron Heating through Landau Resonance with Lower Hybrid Waves at the Edge of Reconnection Ion Jets
Authors: Ren Yong , Dai Lei , Wang Chi , Lavraud Benoit
Published: March 2022

We investigate lower hybrid waves in magnetic reconnection at the flank magnetopause using Magnetospheric Multiscale data. Intense emissions of lower hybrid waves are observed at the density boundary of the reconnection ion jet. Associated with the lower hybrid waves, electrons exhibit signatures of heating in the direction parallel to the magnetic field. Near the Landau resonance energy, the electron fluxes parallel to the magnetic field show oscillations at the same frequency as the lower hybrid waves. The electron flux oscillations are in phase or antiphase with the wave parallel electric field. These observations provide direct evidence for Landau resonance. Our analysis indicates that the density gradient at the edge of the ion jets provides free energy for the lower hybrid waves that further contribute to electron heating through Landau damping. These results shed light on the role of wave−particle interactions in the energy conversion chain of reconnection ion jets.
New Approach for Analyzing Dynamical Processes on the Surface of Photospheric Vortex Tubes

Published: March 2022

The majority of studies on multi-scale vortex motions employ a two-dimensional geometry by using a variety of observational and numerical data. This approach limits the understanding the nature of physical processes responsible for vortex dynamics. Here, we develop a new methodology to extract essential information from the boundary surface of vortex tubes. 3D high-resolution magneto-convection MURaM numerical data has been used to analyze photospheric intergranular velocity vortices. The Lagrangian averaged vorticity deviation technique was applied to define the centers of vortex structures and their boundary surfaces based on the advection of fluid elements. These surfaces were mapped onto a constructed envelope grid that allows the study of the key plasma parameters as functions of space and time. Quantities that help in understanding the dynamics of the plasma, e.g., Lorentz force, pressure force, and plasma-β were also determined. Our results suggest that, while density and pressure have a rather global behavior, the other physical quantities undergo local changes, with their magnitude and orientation changing in space and time. At the surface, the mixing in the horizontal direction is not efficient, leading to appearance of localized regions with higher/colder temperatures. In addition, the analysis of the MHD Poynting flux confirms that the majority of the energy is directed in the horizontal direction. Our findings also indicate that the pressure and magnetic forces that drive the dynamics of the plasma on vortex surfaces are unbalanced and therefore the vortices do not rotate as a rigid body.
The Infrared Database of Extragalactic Observables from Spitzer. II. The Database and Diagnostic Power of Crystalline Silicate Features in Galaxy Spectra

Published: March 2022

We present the Infrared Database of Extragalactic Observables from Spitzer (IDEOS), a homogeneous, publicly available, database of 77 fitted mid-infrared observables in the 5.4–36 μm range, comprising measurements for 3335 galaxies observed in the low-resolution staring mode of the Infrared Spectrometer on board the Spitzer Space Telescope. Among the included observables are polycyclic aromatic hydrocarbon fluxes and their equivalent widths, the strength of the 9.8 μm silicate feature, emission-line fluxes, solid-state features, rest-frame continuum fluxes, synthetic photometry, and a mid-infrared spectral classification. The IDEOS spectra were selected from the Cornell Atlas of Spitzer-IRS Sources. To our surprise, we have detected at a >95% confidence level crystalline silicates in the spectra of 786 IDEOS galaxies. The detections range from single-band detections to detections of all fitted crystalline bands (16, 19, 23, 28, and 33 μm). We find the strength of the crystalline silicate bands to correlate with the amorphous silicate strength and the change from an emission to an absorption feature to occur at higher obscuration as the wavelength of the crystalline silicate band is longer. These observed characteristics are consistent with an origin for the amorphous and crystalline silicate features in a centrally heated dust geometry, either an edge-on disk or a cocoon. We find the 23 and 33 μm crystalline silicate bands to be well suited to classify the obscuration level of galactic nuclei, even in the presence of strong circumnuclear star formation. Based on our detection statistics, we conclude that crystalline silicates are a common component of the interstellar medium of galactic nuclei.
Dependence of the Gleisberg Cycle Period on the Length of Wolf's Numbers Series
Authors: Shibaev Igor , Shibaev Aleksandr
Published: March 2022

The concept of "Gleisberg cycle" arose from the analysis of a small amount of data for a series of Wolf numbers (WSN), which are characterized by varying degrees of reliability and with the key role of cycles 5-7 of the Dalton minimum. Back in the thirties of the last century, when analyzing the first 16 cycles was done, Gleisberg noted the frequency of their maximums in seven to eight cycles, and later gave an updated value of the period - about 80 years. In the works done over the past 60 years, this period is evaluated within 80 - 110 years. A number of researchers allocate a specific value for the Gleisberg cycle period equals to 88 years. Since different authors analyzed a series of Wolf numbers of different lengths, it makes sense to investigate the influence of the length of the series itself on this period.
The paper analyzes the long-period components of WSN versions v1 and v2. The connection between the period and the length of the series is found through the sine approximation of the corresponding fragments. An increase in the sine period from 82 to 110 years (for v1) was obtained with an increase in the length of the series from 18 to 24 cycles and the conditions for the local manifestation of the 88-year harmonic. The initial periodicity of the maximums of seven to eight cycles is transformed into ten to eleven cycles.
The WSN series includes recovered data from 1749 to 1849 and further on, regular observation data - reliable data. The dependence of the period on the length of the series, that is, on the share of reliable data, is associated with the inconsistency of the characteristics of the reconstructed and reliable series and casts doubt on the existence of the Gleisberg cycle or “secular” harmonic in the WSN readings in the 1749-2015 interval. changes in the land cover by temporal analysis.

Authors: Dimitrov Zlatomir
Published: March 2022

This study is focused on utilizing full-polarimetric L-band radar data from ALOS PALSAR (JAXA) by means of Polarimetry (POL-SAR), over mountainous test sites in Bulgaria. General aim is to show feasibility of the Polarimetry to describe natural targets, which exhibits various scattering mechanisms in respect to their bio-physical and geometrical properties. Firstly, the importance of Covariance and Coherent matrices is shown, which is followed by calculation of the polarimetric coherences with their particular significance. The mathematical and physical model based decompositions are applied to describe backscattering media from scattering mechanisms. Radar indices resulted from H/A/α-decomposition showed radnomization of scattering mechanisms over forest areas, whilst two major scattering mechanisms are observed mainly in crop lands. Α comparison is made between polarimetric descriptors from acquisitions in different seasonality over mountainous forest and agricultural lands. Polarimetric segmentations and classifications are applied, with 8 (H/A) and 16 (H/A/α) components. Finally, a forest mask is proposed based on relevant polarimetric descriptors. Study showed good utilization and importance of the full-polarimetric L-band SAR data, derived from ALOS PALSAR, in natural targets and forest areas.

Leading a Multigenerational Nursing Workforce: Issues, Challenges and Strategies
Authors: Sherman Rose
Published: March 2022

Today’s nursing workforce is made up of staff and nursing leaders from four different generational cohorts. Generational diversity, including workforce differences in attitudes, beliefs, work habits, and expectations, has proven challenging for nursing leaders. The purpose of this article is to assist nursing leaders to reframe perceptions about generational differences and to view these differences in attitudes and behaviors as potential strengths. Developing the skill to view generational differences through a different lens will allow the leader to flex their leadership style, enhance quality and productivity, reduce conflict, and maximize the contributions of all staff. This article provides an overview of the generational cohorts and presents strategies which nursing leaders can use to coach and motivate, communication with, and reduce conflict for each generational cohort of nurses.
Nutrition and Disaster Preparedness: Focusing on Vulnerability, Building Capacities
Authors: Wright Marion , Vesala-Husemann Maija
Published: March 2022

Many disasters that occur throughout the world remain largely under-reported, frequently because they began a number of years ago, and have become "chronic" or "long term." Yet, in their vulnerability, the affected populations are no less deserving of humanitarian aid than those involved in the more acute, sudden disasters that make a major impact in the media. Aid providers need to direct their efforts at enabling populations to build their capacity and decrease their vulnerability, thus enhancing their preparedness for any future disaster. This article considers the importance of paying careful regard to the vulnerability, capacities, and disaster preparedness of people affected by these long-term disasters. Vulnerability, capacity, and disaster preparedness are examined specifically in the context of food shortages and malnutrition, with particular reference to the long-term disaster in the African country of Kenya.

Les trois dimensions de la gouvernance coopérative agricole
Authors: Saïsset Louis-Antoine
Published: March 2022

Les coopératives agricoles, qui constituent un mode organisationnel original, subissent de profondes restructurations. Dans le secteur viticole en Languedoc-Roussillon notamment, les types de gouvernance sont en pleine évolution. L’objet de notre travail est d’analyser et de caractériser ce système de gouvernance spécifique, à travers l’étude qualitative de vingt-cinq entretiens avec des dirigeants de coopératives vinicoles du Languedoc-Roussillon. Les principaux résultats montrent l’originalité des organes de gouvernance des coopératives agricoles, se caractérisant par des relations complexes. En outre, grâce à l’analyse textuelle des retranscriptions d’entretiens, nous montrons que la gouvernance coopérative agricole comporte trois dimensions complémentaires dont l’importance est variable d’une coopérative à l’autre : dimension disciplinaire, dimension partenariale et dimension cognitive.
Du service public au service citoyen

Published: March 2022

En France, le service public a été porté à l’idéal, mais, dans les faits, force est de constater qu’il doit évoluer. Le statut Scic pourrait-il permettre de le renouveler ? L’une des mesures de l’utilité sociale des entreprises se fait à l’aune de ses effets sur la société. Le statut Scic permet à certaines entreprises d’avoir un impact large sur les citoyens. L’expérience des Scic du réseau Enercoop donne à voir que son utilité tend à dépasser le seul intérêt de ses membres et bénéficiaires. Dès 1984, en raison de la crise de l’Etat-providence, Pierre Rosanvallon envisageait la possibilité d’expérimenter des « auto-services collectifs » en parallèle ou substitution aux services publics. La Scic peut-elle constituer un outil efficace pour passer, dans certains cas, du service public au service citoyen ?
Articuler communs et économie solidaire : une question de gouvernance ?
Authors: Eynaud Philippe , Laurent Adrien
Published: March 2022

Cet article explore les articulations possibles entre la théorie des communs et celle de l’économie solidaire. Ces deux approches théoriques, tout en s’inscrivant dans des histoires et des démarches conceptuelles fort différentes, ont pour point commun de dépasser un cadre conceptuel uniquement fondé sur l’opposition et/ou la complémentarité entre le marché et l’Etat. L’article se base sur le terrain de recherche du Phares, à la fois coopérative (SCIC) et pôle territorial de coopération économique (PTCE) de la région parisienne, offrant la mutualisation d’un lieu de travail et des espaces collaboratifs à ses membres, des organisations de l’ESS. L’étude montre que la capacité du Phares à mettre en oeuvre une gouvernance collective et à produire du commun pour le territoire est déterminante pour articuler communs et économie solidaire.
Grimper ou se tenir sur la crête. De Deleuze à Paul B. Preciado, ce (ceux.celles) qui nous force à penser
Authors: Mercier Clémence
Published: March 2022

Le présent article propose d’articuler la notion de bêtise telle qu’elle est élaborée par Gilles Deleuze dans ses premiers ouvrages au concept de honte. Dans cette articulation entre pensée philosophique, bêtise et honte, les théories cliniques déployées par Deleuze et Guattari s’imposent comme une élaboration centrale du projet métaphysique porté par Deleuze au travers du concept de bêtise. Le mouvement de pensée initié par Deleuze, prenant une ampleur explicitement clinique et politique avec Guattari, semble être réactivé dans le champ clinique contemporain. Nous observons une actualité (ou une réactualisation) des critiques des théories psychanalytiques et psychiatriques qu’ils ont déployées dans les années 70. La figure deleuzienne de l’idiot permet de penser le type de position qu’occupent les auteurs et les autrices qui, actuellement, soulèvent les enjeux épistémologiques, politiques et cliniques du genre. Sur son revers, elle interroge ce que l’idiotie, au sens deleuzien, fait à la bêtise et à la honte.
Psychological Distress and Unmanaged Negative Emotions: Examining Resilience Among Nurses Working on COVID-19 Designated Inpatient Units
Authors: Fredericks Suzanne , Lapum Jennifer , McShane Julie , Lai Sannie , Nguyen Megan
Published: March 2022

Anecdotal evidence suggests nurses are engaging in resilience-based strategies to mitigate increased levels of psychological distress and unmanaged negative emotions they have been experiencing. Nurses' levels of resilience during the coronavirus disease 2019 (COVID-19) pandemic have not been clearly articulated, specifically in relation to psychological distress and negative emotions. The purpose of the current mixed-methods non-experimental descriptive study was to examine nurses' resilience during the pandemic. Sixty RNs working in acute care hospitals on inpatient units designated to care for patients with COVID-19 completed the study survey and 20 of these RNs completed an interview. Findings indicate moderate levels of resilience among participants, with the need to increase resources and support emerging as a common theme among the qualitative data. Suggestions for integration of resilience-based strategies into the clinical setting, such as creation of a dedicated space for nurses to engage in mindfulness, relaxation, and meditation, were put forward.

The Adsorption of Perfluorooctanoic Acid on Coconut Shell Activated Carbons
Authors: Kanchanapiya Premrudee , Songngam Supachai , Tantisattayakul Thanapol
Published: March 2022

Perfluorooctanoic acid (PFOA) is one of Per- and polyfluoroalkyl substances (PFAS) that have increasingly attracted concerns due to their global distribution in environment, persistence, high bioaccumulation and toxicity. It is important to study the effective treatment to remove PFOA from contaminated water. The feasibility of using commercial coconut shell activated carbon produced in Thailand to remove PFOA from water was investigated with regard to their adsorption kinetics and isotherms of powder activated carbon (PAC-325) and granular activated carbon (GAC-20x50). Adsorption kinetic results show that the adsorbent size significantly affected the adsorption rate of PFOA, and GAC-20x50 required at least 100 h to achieve the equilibrium, much longer than 3 h for PAC-325. Two kinetic models were fitted to the experimental data, and the pseudo-second-order model well described the adsorption of PFOA on both PAC-325 and GAC-20x50. PAC-325 trended to adsorb PFOA faster than GAC-20x50 and testing with the shortest adsorption times (5 min) still yielded substantial PFOA removal (~80% for PAC-325). The adsorption isotherms show that the adsorption capacity of PAC-325 was 0.80 mmol/g, which is 83 % higher than that for GAC-20x50 (0.13 mmol/g), according to the Langmuir fitting.
On the representation of informational structures in games
Authors: Luckraz Shravan
Published: March 2022

We consider two well-known mathematical representations of informational structures in game theory. The first is based on the set of historical sequences of information encountered in the game while the second is given by the informational digraph of the game. We show that while the latter can always be embedded into the former under some mild technical condition, the converse does not hold in general. We give a necessary and sufficient condition for an informational digraph to be equivalent to a sequence theoretic informational structure and discuss the relevance of this result to game theory.

Published: March 2022

In this work, lossless compression is considered and an efficient Encryption–then-compression (ETC) scheme is proposed for medical images. A considerably good level of security is achieved by the proposed scheme where image encryption is operated in the prediction error domain.  In addition, reasonably good compression of the encrypted medical images is achieved. Comparison is done between Gradient adjusted prediction (GAP) & Median Edge Detector (MED) techniques and GAP is found to perform better with respect to PSNR, bit rate and entropy.  The average values of PSNR, bit rate and entropy in decibels for MED predictor are 10.8313, 3.7695 and 3.8624 respectively. Similarly, for GAP predictor, the average values of PSNR, bit rate and entropy in decibels are 11.9025, 4.0279 and 4.1286 respectively.

Musculoskeletal models endow an opportunity to study the movement of the upper limb in vivo. The solid foundation of musculoskeletal model design is inherited from musculoskeletal parameters. Some of these parameters are tendon and muscle fiber length, pennation angle, and muscle volume. It is possible to extract these parameters based on cadaver. However, it is time-consuming and gives a generic statement about the function of the musculoskeletal system, but this is not enough to get accurate data and timely for each patient. Medical imaging has revolutionized visualization of the internal structure of the body in real time and in vivo. It is worth using medical imaging because it is impossible to imagine in real time what is inside the body unless surgery is performed; it is possible to see internal structure through cadaver dissection, but not in vivo. There are several kinds of medical imaging tools, which have been used in musculoskeletal system analysis such as Ultrasonography (US), Magnetic Resonance Imaging (MRI), Diffusion Tensor Imaging (DTI) and Computer Tomography (CT) scans. The work proposed aims to present principle, development and challenges of different medical imaging tools of musculoskeletal system methods. The results of this study show that the choice of imaging device for the musculoskeletal system depends mainly on the motivation, target and the strong points that present in the medical imaging devices.

The purpose of his study is to determine the factors that influence the sustainability of entrepreneurial business operations in the Lower Northeastern Area of Thailand, across varies industries. We followed the marketing mix (5P) model exploring product perspective, price perspective, distribution channel, promotion perspective and people perspective and their influence on entrepreneurial business operations sustainability. There was a strong emphasize on the quality and quantity of products provided as well as uniqueness of the products and services developed by the entrepreneurs. Price was less important as long as it was competitive. Location was the most important factor when it came to distribution channel especially for service businesses. Online businesses were slowly developing. Customers preferred brick and mortar family businesses with knowledgeable and friendly entrepreneurs who are service oriented. People make the difference in the sustainability of entrepreneurial operations.

Published: March 2022

In India, e-commerce sector is rising at an enormous pace, but even larger share is in the hands of offline retailers till now. A unique type of consumer behaviour has been seen because of the simple accessibility of the internet, where the customer searches for products and its information on the internet and then buys them offline. With this the researcher is here analysing the mediating effect of perceived ease of use on adoption of M-commerce services with the usage of advance mobile network generations. Data were collected from 616 respondents by making stratas of respondents in such a way that different telecom users who are doing online transactions were taken. Data were analysed by using Structural Equation Modeling technique and it was examined that the mediator (perceived ease of use) has a great impact on M-commerce adoption.

Published: March 2022

The researchers seek to provide a Gamification model that will help children of Sri Lanka improve their oral hygiene habits, thereby acting as a change agent to influencing adults’ behaviors to have good oral hygiene habits. The nature of the study was a multi-method due to its complexity. The study took place within 13 weeks, where data was longitudinally collected from 50 families in a natural environment. Both descriptive statistics and quantitative methods were used to analyze the data. Our findings suggest that expedient designs need to consider all four clusters, namely System Design, Challenges, Rewards, and Social Influences, as interdependencies among these clusters enable and amplify the effectiveness of Gamification. Our findings should be of particular interest since they generally show vast potential to motivate children through Gamification. Organizations should not see Gamification as a ‘magic bullet’ for end-user motivation but as a means that must be carefully and deliberately integrated into the model to support a motivational culture that would prompt sustainable behavior.

Introduction: Tuberculosis remains a global health burden. Among all sites, cutaneous tuberculosis represents an uncommon manifestation with myriad presentations which explains the high rate of misdiagnosis. We aimed to study the epidemiological, clinical, and therapeutic features of cutaneous tuberculosis in southern Tunisia.
Methods:  A retrospective study including all patients diagnosed with extrapulmonary tuberculosis was conducted  in the south of Tunisia between 1998 and 2019. This study specified the particularities of cutaneous tuberculosis cases over a 22-year period.
Results: We encountered 1663 cases of extrapulmonary tuberculosis, among whom 56 cases were cutaneous tuberculosis (3.3%).  Thirty eight (38) were  women (67.9%). The mean age was 43±20 years. Multifocal tuberculosis was noted in 12 cases (21.4%). Systemic symptoms of tuberculosis represented by asthenia (55.3%), fever (42.8%) and weight loss (37.5%) were noted. Elevated C-reactive protein levels (50%) and accelerated erythrocyte sedimentation rates (42.8%) were also noted. The diagnosis was confirmed  histologically (80.4%) and microbiologically (12.5%) . The median duration of antitubercular therapy was 11(9-14) months for multifocal tuberculosis cases (12 cases) and 8(6-12) months for cutaneous tuberculosis cases without any other sites of tuberculosis (44 cases). Adverse effects were noted in 14 cases (25%). The disease evolution was favorable in 54 cases (96.4%). Two patients had a relapse (3.6%).
Conclusions:  Cutaneous tuberculosis remains a common disease in  south Tunisia. Patients should be screened for cutaneous tuberculosis starting with a general skin examination. Skin biopsy, the cornerstone of the diagnosis should be performed on any suspected cutaneous lesion.

OBJECTIVES:

Since the beneficial effect attained by mechanical thrombectomy (MT) seems to be worse in older than in the younger population, the establishment of an ideal and distinctive patient selection protocol in older is warranted. Herein, we modified our patient selection protocol based on age and premorbid independence in older adult patients.

MATERIALS AND METHODS:

We retrospectively reviewed 141 consecutive patients with acute ischemic stroke who were treated with MT between 2015 and 2020. We started to restrict the indication of MT in very old patients (≥85-year-old) with severe premorbid functional independence (≥modified Rankin Scale [mRS] 3) in 2018. Clinical outcomes before the modification of protocol (period 1) were compared to after (period 2).

RESULTS:

Although there were no significant differences in median mRS at 90 days and the rates of favorable outcomes (mRS 0–2) between both periods, rates of poor outcomes (mRS 5, 6) significantly decreased (37.3% vs. 19.7%, P = 0.021) during period 2 compared with period 1. For older adults (≥80-year-old), median mRS was significantly better (P = 0.012) during period 2 than period 1. During period 1, rates of favorable outcomes were significantly lower (P = 0.004) in older than in younger. However, this significant difference was diminished (P = 0.28) during period 2.

CONCLUSION:

Our modified patient selection protocol in older adults, not only limited by age but also premorbid function, improved the therapeutic outcome of MT. In rapidly aging society, further investigations facilitating a better understanding are necessary to establish an optimal patient selection protocol.
Uncommon Etiology of Upper GI Bleed
Authors: Varadarajulu Hema Vijayalakshmi
Published: March 2022

Abnormal fistulous communications between the esophagus and respiratory tract are life-threatening conditions which need to be diagnosed at the earliest and managed appropriately. Bronchoesophageal fistula (BEF) is a rare endoscopic finding. It is commonly due to esophageal malignancy in adults, benign etiologies being very rarely encountered during endoscopy. In this case report, we discuss a BEF arising from a mid-esophageal diverticulum, which presented with recurrent hematemesis.

Pancreatico-enteric stenosis (PES) is a long-term complication following pancreaticoduodenectomy (PD). The incidence of clinically relevant PES is likely to improve with better outcomes following PD for benign and neoplasms with favorable prognosis. Endoscopy and surgical techniques have been described addressing PES with revision of pancreatico-enteric anastomosis (PEA) being the most common performed surgery. Dense adhesions in the lesser sac especially after postoperative pancreatic fistula can be prohibitive to access the PEA. We describe a technique for postPD PES, transgastric pancreaticogastrostomy, that avoids lesser sac dissection and enables performing a wide anastomosis. Thus, it has the potential to reduce postoperative morbidity.
Autoimmune Pancreatitis Presenting as Obstructive Jaundice – A Diagnostic Challenge

Autoimmune pancreatitis (AIP) is a rare form of pancreatitis which can mimic carcinoma head of the pancreas or distal cholangiocarcinoma, causing the diagnostic dilemma. A 64-year-old postmenopausal woman presented with jaundice, generalized itching, and intermittent low-grade fever for 2 weeks. On evaluation, she had a bulky pancreas on imaging and distal biliary stricture on magnetic resonance cholangiopancreatography. She was planned for Whipple's resection, but her serum immunoglobulin G4 (IgG4) was very high. She was started on oral high-dose steroids considering the possibility of AIP and had significant improvement after 2 weeks of treatment. AIP can mimic distal cholangiocarcinoma and can cause a diagnostic challenge in patients admitted with obstructive jaundice. The presence of high serum IgG4 level and treatment response to steroids help in making the diagnosis. This case reminds the readers to consider AIP in patients with obstructive jaundice who have imaging findings of distal cholangiocarcinoma to avoid unnecessary operations on patients without cancer.
