Investigating the Effects of Vortex Generator Geometry on NACA Inlet Performance
Authors: Kharis Rinal , Harinaldi Harinaldi
Published: September 2024

The NACA inlet is a submerged inlet that is widely used in aviation. It has the advantages of low drag and low radar cross-section. One of the considerations in using the NACA inlet is the low-pressure recovery compared to other types of inlets. To improve the pressure recovery of the NACA inlet, it can be done by controlling the boundary layer thickness in the upstream of the NACA inlet. This study aims to investigate the effect of the use and geometric parameters of vortex generators on the improvement of the performance of the NACA inlet. The geometric parameters that will be varied are height, angle of incidence, and distance between vortex generators. Various configurations will be simulated numerically with ANSYS Fluent using the k-ω SST turbulence model. The results indicate that the use of vortex generators can increase the Ram recovery ratio by 31.23% and the Mass flow ratio by 14.74%. The most effective vortex generator height to use depends on the local boundary layer thickness. The effective angle of incidence and spacing of the vortex generator were obtained at 20 degrees and 20 mm, respectively. These results indicate that there are effective angles and spacings in the vortex generator configuration to improve the performance of the NACA inlet.

Authors: Akter Farjana , Akter Nipa Marjia , Hossain Md.Mahbub
Published: September 2024

Introduction: In hospital patients, infections continue to develop and may also be affected by hospital personnel despite progress in the field of public health and hospital care. Infection among hospitable patients is encouraged by many factors: reduced immunity among patients; increasing variety of medical procedures and invasive techniques that lead to potential routes for infection; and transmission among crowded hospital populations of drug-resistant bacteria, where low infect control practices can facilitate transmission. Nosocomial infections occur globally and affect developing countries as well as poor- resource countries. The major causes of death and increased morbidity include infections acquired in health care.  Objective: To find out the Knowledge, Attitude and Practice of Staff nurses on Hospital Acquired Infections in tertiary care Hospital of Dhaka city.  Method: The study was conducted by Cross sectional, descriptive quantitative research study design with 133 samples included with the inclusion criteria. Data were collected by face to face interviewed method.  Results: Among of the participants, the majority of the nurses were Diploma in Nursing 64.4%, B.Sc. in Nursing 23.7% and MPH/M.Sc. were 11.9%. Distribution of the participants by level of knowledge on hospital acquired infections (n=133), Here the most of the participants had moderate 46% (n=61) knowledge about hospital acquired infections.  Conclusion: Most of the nurses do not have a perfect knowledge about hospital acquired infection control. Therefore, it must be necessary that to learn the knowledge, control and prevention of hospital acquired infections. We also must be known how can use medical personnel about the prevention and control of HAIs according to world standards. Another way of gain knowledge from training, Presentation, academic courses, posters, and conferences.

Authors: SIHITE Riduan , WIBISONO Chablullah , CATRAYASA I Wayan , SATRIAWAN Bambang
Published: September 2024

The Karimun Regional Government issued a policy to extend the contracts of 75 contract workers out of the 80 contract workers in BPKAD Karimun Regency. Contrary to this policy, thousands of ASNs in Karimun Regency have only paid their salaries, which has an impact on decreasing employee satisfaction, which results in increasing employee absences without explanation. This quantitative research analyzes the relationship between transactional leadership, organizational commitment, career development, job satisfaction, and work motivation as intervening variables. It was concluded that transactional leadership and work motivation had a significant effect on job satisfaction, and job satisfaction significantly impacted work motivation. Organizational commitment and career development do not significantly affect job satisfaction. Organizational commitment does not substantially affect work motivation, while career development has a significant effect. Then transactional leadership and career development have a significant effect on job satisfaction when intervened by work motivation, while organizational commitment does not have a significant impact on job satisfaction when intervened by work motivation. It is recommended that leaders at the Karimun Regency BPKAD agency increase employee liking for the work given, support from colleagues in achieving targets, opportunities for promotion and work monitoring systems by employee and work conditions through, among other things, providing rewards for employee performance, creating and ensuring implementing regulations that can control employee safety and comfort, optimizing the provision of employee human standards, fair treatment at work, increasing employee awareness and understanding of career opportunities in the agency.

Interstellar Glycolaldehyde, Methyl Formate, and Acetic Acid. II. Chemical Modeling of the Bimodal Abundance Pattern in NGC 6334I
Authors: Shope Brielle M. , El-Abd Samer J. , Brogan Crystal L. , Hunter Todd R. , Willis Eric R. , McGuire Brett A. , Garrod Robin T.
Published: September 2024

Gas-phase abundance ratios between C2H4O2 isomers methyl formate (MF), glycolaldehyde (GA), and acetic acid (AA) are typically on the order of 100:10:1 in star-forming regions. However, an unexplained divergence from this neat relationship was recently observed toward a collection of sources in the massive protocluster NGC 6334I; some sources exhibited extreme MF:GA ratios, producing a bimodal behavior between different sources, while the MF:AA ratio remained stable. Here, we use a three-phase gas-grain hot-core chemical model to study the effects of a large parameter space on the simulated C2H4O2 abundances. A combination of high gas densities and long timescales during ice-mantle desorption (∼125–160 K) appears to be the physical cause of the high MF:GA ratios. The main chemical mechanism for GA destruction occurring under these conditions is the rapid adsorption and reaction of atomic H with GA on the ice surfaces before it has time to desorb. The different binding energies of MF and GA on water ice are crucial to the selectivity of the surface destruction mechanism; individual MF molecules rapidly escape the surface when exposed by water loss, while GA lingers and is destroyed by H. Moderately elevated cosmic-ray ionization rates can increase absolute levels of “complex organic molecule” (COM) production in the ices and increase the MF:GA ratio, but extreme values are destructive for gas-phase COMs. We speculate that the high densities required for extreme MF:GA ratios could be evidence of COM emission dominated by COMs desorbing within a circumstellar disk.
Force-free Wave Interaction in Magnetar Magnetospheres: Computational Modeling in Axisymmetry
Authors: Mahlmann Jens F. , Aloy Miguel Á. , Li Xinyu
Published: September 2024

Crustal quakes of highly magnetized neutron stars can disrupt their magnetospheres, triggering energetic phenomena like X-ray and fast radio bursts. Understanding plasma wave dynamics in these extreme environments is vital for predicting energy transport across scales to the radiation length. This study models relativistic plasma wave interaction in magnetar magnetospheres with force-free electrodynamics simulations. For propagation along curved magnetic field lines, we observe the continuous conversion of Alfvén waves to fast magnetosonic (FMS) waves. The conversion efficiency can be up to three times higher when counter-propagating Alfvén waves interact in the equatorial region. Alfvén waves generate FMS waves of twice their frequency during their first crossing of the magnetosphere. After the initial transient burst of FMS waves, Alfvén waves convert to FMS waves periodically, generating variations on timescales of the magnetospheric Alfvén wave crossing time. This decaying FMS wave tail carries a significant portion (half) of the total energy emitted. Plastic damping of “bouncing” Alfvén waves by the magnetar crust has minimal impact on the FMS efficiency. We discuss the implications of the identified wave phenomena for magnetar observations. Outgoing FMS waves can develop electric zones, potential sources of coherent radiation. Long wavelength FMS waves could generate FRBs through reconnection beyond the light cylinder.
Precise Transit Photometry Using TESS. II. Revisiting 28 Additional Transiting Systems with Updated Physical Properties
Authors: Saha Suman
Published: September 2024

Precise physical properties of the known transiting exoplanets are essential for their precise atmospheric characterization using modern and upcoming instruments. Leveraging the large volume of high-signal-to-noise-ratio photometric follow-up data from TESS, highly precise physical properties can be estimated for these systems, especially for those discovered using ground-based instruments prior to the TESS mission. In this work, I have used the publicly available TESS follow-up data for 28 transiting systems with 10 < V
mag < 10.5, with an aim to update their known physical properties. The observed lightcurves have been analyzed by implementing a state-of-the-art critical noise treatment algorithm to effectively reduce both time-correlated and uncorrelated noise components, using sophisticated techniques like wavelet denoising and Gaussian-process regression. Compared with the previous studies, the estimated transit parameters are found to be more precise for most of the targets, including a few cases where a larger space-based instrument like Spitzer, Kepler, or CHEOPS has been used in the previous study. The large volume of transit observations used for each target has also resulted in a more accurate estimation of the physical properties, as this overcomes any error in parameter estimations from bias present in a smaller volume of data. Thus, comparing with the literature values, statistically significant improvements in the known physical properties of several targeted systems have been reported from this work. The large volume of transit-timing information from the analyses was also used to search for transit-timing variation trends in these targets, which has resulted in no significant detection.
Irregular Moons Possibly Injected from the Outer Solar System by a Stellar Flyby

The irregular moons orbit the giant planets on distant, inclined, and eccentric trajectories, in sharp contrast with the coplanar and quasicircular orbits of the regular moons. The origin of these irregular moons is still an open question, but these moons have a lot in common with the objects beyond Neptune (trans-Neptunian objects—TNOs), suggestive of a common origin. Here, we show that the close flyby of a star may be the connecting element. A stellar flyby can simultaneously reproduce the complex TNO dynamics quantitatively while explaining the origin of the irregular moons and the color distributions of both populations. This flyby would have catapulted 7.2% of the original TNO population into the region of the planets, many on retrograde orbits. Most injected TNOs would have been subsequently ejected from the solar system (85%). However, a considerable fraction would have had the potential to be captured by the planets. The exclusively distant origin of the injected TNOs may also explain the lack of very red irregular moons.

Colletotrichum species are significant pathogens of various economic plant hosts worldwide. In this study, 45 Colletotrichum isolates were obtained from symptomatic walnut leaves of walnut anthracnose in Shaanxi and Sichuan Provinces. In conjunction with morphological evidence and multi-gene phylogenetic analyses of internal transcribed spacer (ITS), actin (act), chitin synthase 1 (chs1), glyceraldehyde-3-phosphate dehydrogenase (gapdh) and beta-tubulin (tub2) sequences support the introduction of three new species, namely Colletotrichum cordae, C. guangyuanense and C. juglandium. Five species of Colletotrichum were identified to be C. fioriniae of the C. acutatum species complex, C. karsti of the C. boninense species complex, C. gloeosporioides, C. mengyinense and C. siamense of the C. gloeosporioides species complex. The three new species are described and illustrated in this paper and compared with taxa in the Colletotrichum gloeosporioides species complex. The current results improve the understanding of Colletotrichum species causing walnut anthracnose in China.

A new karst-dwelling bent-toed gecko of the Cyrtodactylus intermedius group is described from Khlong Hat District, Sa Kaeo Province, eastern Thailand, based on an integrative taxonomic analysis of genetic data and morphological characteristics. Phylogenetic analyses using the mitochondrial NADH dehydrogenase subunit 2 (ND2) gene revealed that topotypes of C. intermedius were sister to a clade containing C. kulenensis from Cambodia, an unnamed lineage from Sakaerat Biosphere Reserve in Nakhon Ratchasima Province, Thailand, and the Khlong Hat lineage described here as Cyrtodactylus khlonghatensissp. nov. Multivariate analyses of morphometric and meristic characters showed that C. khlonghatensissp. nov. is morphologically distinct from all other species in the group by having the combination of SVL 76.5–82.8 mm in adult males and 88.5 mm in an adult female; eight supralabial and nine infralabial scales; 30–32 paravertebral tubercles; 20 or 21 longitudinal rows of dorsal tubercles; 43 or 44 ventral scales; seven or eight expanded subdigital lamellae on the 4th toe; 12 unmodified subdigital lamellae on the 4th toe; 19 or 20 total subdigital lamellae on the 4th toe; 31 or 32 total number of enlarged femoral scales; enlarged femoral and precloacal scales continuous; 6–8 pore-bearing precloacal scales in males; three or four rows of enlarged post-precloacal scales; 1–3 postcloacal tubercles; proximal femoral scales less than one-half the size of distal femoral scales; absence of interdigital pocketing between digits of forefeet and hindfeet; and posterior border of the nuchal loop rounded. Uncorrected pairwise genetic divergences (p-distances) between the new species and other species of the intermedius group ranged from 4.73–22.55%. The discovery of this new species exclusively in isolated karst formations from the Thai-Cambodia border suggests that there may be further undiscovered Cyrtodactylus in unexplored karst landscapes along the border of eastern Thailand and western Cambodia.
Etre ergothérapeute en psychiatrie

L’intérêt supérieur de l’enfant – Un dialogue entre théorie et pratique
Authors: Nyman Johanna
Published: September 2024

Johanna Nyman s’intéresse au principe d’intérêt supérieur de l’enfant du point de vue des droits des jeunes. Elle souligne que les droits à la participation (article 12 de la CIDE) constituent l’un des aspects les plus importants de ce principe. La participation est aussi l’un des piliers de l’action du Forum européen de la jeunesse. Selon Johanna Nyman, la manière la plus efficace d’encourager la participation des enfants et des jeunes est de passer par les organisations représentatives démocratiques. Les jeunes doivent pouvoir participer à la vie de la société. Leur niveau de participation doit toutefois toujours être adapté à leurs capacités actuelles car celles-ci se développent au fil du temps. Le Protocole facultatif à la CIDE établissant une procédure de présentation de communications offre aux enfants de nouvelles possibilités de prendre part aux décisions qui les concernent. Mais qu’advient-il lorsqu’un enfant atteint l’âge de 18 ans puisqu’il est désormais exclu du champ d’application de la CIDE ? La transition de l’enfance à l’âge adulte mérite donc toute notre attention. Des travaux de recherche sur les droits fondamentaux des jeunes et sur l’incidence des mesures de politique publique sur les enfants et les jeunes constitueraient un bon point de départ pour explorer plus avant les différences entre les politiques traditionnelles de l’enfance et de la jeunesse.

Published: September 2024

Purpose

To examine relationships among secondary traumatic stress, mindfulness, compassion satisfaction, and compassion fatigue in psychiatric nurses.

Method

Participants comprised 142 nurses working in two psychiatric hospitals in the same province of Turkey. Data were collected using a personal information form, the Secondary Traumatic Stress Scale, Mindful Attention Awareness Scale, and Compassion Fatigue and Compassion Satisfaction subscales of the Professional Quality of Life Scale.

Results

A significant and negative correlation was found between secondary traumatic stress, mindfulness, and compassion satisfaction, and between mindfulness and compassion fatigue. A significant and positive correlation was found between secondary traumatic stress and compassion fatigue, as well as between mindfulness and compassion satisfaction (
p
< 0.05).

Conclusion

Findings demonstrate that mindfulness may be a protective factor in preventing secondary traumatic stress and compassion fatigue in psychiatric nurses. It is recommended that in-service training be organized periodically to increase levels of conscious awareness among psychiatric nurses. [
