Published: October 2022

The instability and transition of hypersonic boundary layer on a blunted delta wing is performed by numerical simulation of experiments conducted in the quiet wind tunnel. Disturbances are calculated using linear stability theory to obtain the integrated disturbance growth rates and amplification factors from laminar steady base flows. Comparisons are made between the results of the stability analysis and the experimentally measured transition characteristics. The results show that the generalized inflections existing in velocity profiles reveal both the streamwise instability and crossflow instability of the boundary layer on the delta wing. In the parameter spaces of frequency and wave number, there is only one unstable region in which the first-mode and second-mode waves are integrated with each other at [Formula: see text] angle of attack, whereas the unstable regions of the first-mode and second-mode waves are separately distributed at angle of attack of [Formula: see text]. The numerically predicted [Formula: see text] factor distribution is in good agreement with the measured transition front, and the [Formula: see text] factor is about 3 when boundary-layer transition occurs. The low-frequency unstable waves with about 25–30 kHz play a key role in dominating the boundary-layer transition of the delta wing.

Authors: Rahma D Indira , Suryono Sombu Alwin 
Published: October 2022

Abstrak - Dalam konteks arsitektur masa kini, banyak karya arsitektur yang mencoba mengembalikan nilai-nilai dan bentuk fisik arsitektur tradisional, sebagai bentuk pelestarian arsitektur masa lampau dalam konteks waktu masa kini, dan merupakan pengembangan dari konsep-konsep tradisional dengan teknologi yang lebih maju.
Penelitian ini bertujuan untuk mengungkap wujud budaya Jawa yang terkandung dalam struktur dan konstruksi, serta tektonika Masjid Said Naum, serta tindakan-tindakan pelestarian yang terjadi di dalamnya. Atribut spesifik yang diteliti adalah struktur dan konstruksinya, dengan lingkup tektonika ruang, struktur, dan ornamen. Penelitian ini menggunakan metode kualitatif yang menjabarkan pengamatan struktur dan konstruksi Masjid Said Naum menggunakan teori tektonika beserta identifikasi wujud budaya Jawa yang terkandung di dalamnya, sehingga menemukan tindakan-tindakan yang diambil dalam melakukan pelestarian budaya Jawa.
Hasil penelitian mengungkap budaya Jawa yang dilestarikan pada sistem struktur dan konstruksi, serta tektonika Masjid Said Naum dalam wujud artefak, aktivitas, dan gagasan. Tindakan pelestarian yang dilakukan adalah tindakan adaptasi dan preservasi.
Terjadi tindakan adaptasi wujud artefak budaya Jawa pada elemen-elemen fisik Masjid Said Naum, dimana banyak terjadi reinterpretasi oleh arsitek, seperti penghilangan kolom soko guru dan inovasi bentuk tajug untuk memanfaatkan material dan teknologi yang lebih modern, namun dari segi aktivitas sebagian besar masih dipreservasi karena mengingat fungsi masjid yang sejalan dengan aktivitas beribadah dan status sosial masyarakat Jawa. Wujud gagasan budaya Jawa mengalami tindakan adaptasi dan preservasi, dimana adaptasi terjadi sebagai bentuk pergerakan bahasa ruang dan struktur yang lebih modern, dan preservasi dari prinsip-prinsip karakter orang Jawa yang saling mendukung dan menjaga keseimbangan diri dengan alam.
Dapat disimpulkan bahwa struktur dan konstruksi Masjid Said Naum, meskipun telah mengalami proses adaptasi yang ekstensif untuk menyesuaikan diri terhadap konteksnya, tetap menghasilkan produk arsitektur yang melestarikan budaya Jawa, terutama pada tatanan struktur yang sejalan dengan konsep ketuhanan di Jawa, dan ekspresi struktur yang jujur dan apa adanya namun tetap memiliki makna pada setiap elemen dan penempatannya.

Extensión de la muda preformativa del buscabreña (Icteria virens) a partir de individuos capturados durante la migración de otoño en el sur del estado de Veracruz, México
Authors: Grosselet Manuel , Nochebuena Jaramillo Jonathan Ruben , Rodríguez Ramos Gerardo , Ruiz Michael Georgita 
Published: October 2022

El estudio del proceso de muda de las aves neotropicales ha tenido gran relevancia a partir de la publicación de guías especializadas, pero el conocimiento en este campo aun es escaso. La mayoría de los estudios sobre muda se realizaron con tamaños de muestra pequeños de menos de 100 individuos. En este estudio, hemos elegido a Icteria virens, una especie muy estudiada y con una distribución muy amplia en Norteamérica; analizamos una muestra de 626 individuos en su primer año de vida. La investigación la llevamos a cabo en el sur del Golfo de México con poblaciones migratorias norteñas posiblemente provenientes del este del continente con base en diferencias morfométricas del tarso y una recaptura reciente. Los resultados arrojan diferencias evidentes con lo anteriormente reportado acerca del proceso de la muda preformativa. Sugerimos que dicho proceso varía según el origen geográfico de las aves y muestra que la descripción de la muda debe basarse en una muestra amplia de individuos. Este trabajo propone enfocar estudios sobre el patrón de muda por corredores migratorios, con el fin de estimar el desarrollo de cada sub-población y estimar el proceso de muda entre poblaciones del oeste y del este de Norteamérica.

Published: October 2022

Background: Therapeutic music has been shown to provide significant physical and mental health benefits to patients, yet limited information is available on the impact of live classical music in the intensive care unit (ICU) setting.
Objective: The purpose of this initiative was to implement and evaluate a therapeutic music program in the ICU.
Methods: A descriptive survey methodology was used to obtain information from volunteer musicians and clinical nurses. Researchers used a 12-item anonymous web-based survey to collect information on the therapeutic music program's acceptability, appropriateness, and feasibility. The survey also included questions addressing potential barriers to and facilitators of implementing therapeutic music in the ICU.
Results: A total of 15 nursing staff and 6 volunteer musicians completed the online survey. Of the 15 nurse respondents (9 clinical nursing staff, 3 advanced practice, 3 other), a majority (n=10, 66.7%) identified that therapeutic music was acceptable in the ICU. Similarly, a majority (n=11, 73.3%) indicated that therapeutic music was appropriate and feasible. Of the volunteer musicians, all (n=6, 100%) identified several factors that helped to facilitate the program including having an upright piano with large casters (wheels) for enhanced mobility to play music. Most (n=5, 83.3%) identified having a patient and family-centered care environment and supportive ICU staff, and four (66.7%) identified private ICU rooms and trained musicians as useful. Several barriers were also identified, including severity of patient illness and infection prevention concerns (n=5, 83.3%), space limitations in the ICU and patient privacy concerns (n=2, 33.35%), and patients being asleep (n=1, 16.75%).
Conclusions: The results of this initiative indicated that therapeutic music in the ICU was rated as acceptable, appropriate, and feasible. Volunteer musicians reported the ability to provide live music in the ICU to be a beneficial and enjoyable experience. The program has been transitioned to a virtual format using a large iPad on wheels due to COVID-19-related visitation restrictions.
Unit Knowledge and Practice of Emergency Nursing Interventions at a Tertiary Public Cardiac Health Center in Uganda
Authors: Namukwaya Harriet , Aliga Cliff , Nakate Mary , Mutyabule Judith 
Published: October 2022

Background: Research suggests that many of the millions of deaths and long-term disabilities resulting from acute cardiovascular events and other emergency conditions are preventable if effective emergency care services were readily available. Effective emergency care requires trained and competent staff, including registered nurses. Most educational pathways do not adequately prepare nurses to deliver sensitive health care services for those with acute illness and injury. This includes Uganda, where few capacity-building initiatives have targeted emergency nursing care delivery, leading to knowledge and practice gaps.
Purpose: This study aimed to assess emergency nursing knowledge and clinical practice at a tertiary public cardiac health facility in Uganda.
Method: This was a single-center, descriptive cross-sectional survey of a convenience sample of nurses working in the emergency department.
Results: A total of 49 emergency care nurses completed the survey (response rate of 81.6%). Among the participants, 75.5% were females, 65.3% had a bachelor's degree, 28.6% had Basic Life Support training, and 12.2% were certified in Advanced Cardiac Life Support. Additionally, 75% of the respondents had low proficiency in assessing critically ill patients, 100% could not perform safety checks, 50% were unable to maintain patent airways or complete patient handover, and only 50% could connect a patient to a defibrillator.
Conclusion: We report that the most significant gap in nurse-provided emergency care is the application of practical skills. Capacity-building initiatives are required to improve the knowledge and practice of nurses in emergency care delivery.

Spinach is a plant usually cultivated for its leaves to be consumed as green vegetables. Spinach contains vitamins, protein, fat, carbohydrates, and minerals. Research on the effect of Vermicompost and NPK fertilizer on the growth of spinach has been carried out from July to September 2021 in Lombok, Indonesia. The objectives of the study are to determine: (1) the effect of Vermicompost on the growth of spinach, (2) the effect of NPK fertilizer on the growth of spinach, (3) the interaction effect of Vermicompost and NPK fertilizer on the growth of spinach. This research was conducted experimentally using a factorial, completely randomized design with two factors and three replications. The first factor was the dose of NPK fertilizer which consisted of 4 treatment levels, namely 0 g, 0.5 g, 1 g, and 1.5 g for each plant. The second factor is the dose of Vermicompost, which consists of 5 levels, namely 0 kg, 0.6 kg, 1.2 kg, 1.8 kg, and 2.4 kg for 1 m2 of agricultural land. The vermicompost treatment was carried out ten days before planting. The NPK fertilizer treatment was carried out ten and 20 days after planting. Spinach growth parameters were stem diameter, plant height, total leaf, leaf length, and leaf width. The results of the study were: (1) the treatment of NPK fertilizer had a significant effect on the number of leaves, leaf length, leaf width, stem height, and stem diameter of spinach, (2) the application of Vermicompost had a significant effect on the number of leaves, leaf length, leaf width, and stem height but did not significantly affect the diameter of the stems, (3) the optimum dose of NPK fertilizer was 1 gram per plant, (4) treatment 1.8 kg vermicompost resulted in better growth of spinach compared to other.

Published: October 2022

Aloe vera Linn. is an essential medicinal plant. In this present research work, a protocol of in vitro regeneration and karyomorphological analysis of Aloe vera was developed using different concentrations and compositions of media. Shoot apices of field-grown plants were used as explant and aseptically cultured on Murashige and Skoog (MS) medium fortified with different concentrations and combinations of auxins (IAA and NAA) and cytokinins (BAP and Kn). The highest number of multiple shoot buds (4.36 ± 0.07) was obtained from MS + 2.0 mg/l BAP + 1.0 mg/l IAA and induced shoot buds underwent rapid elongation (4.24 ± 0.06 cm) on the same medium composition. Half strength MS media with 2.0 mg/l IBA was suitable for induction and proliferation (6.31 ± 0.05) of roots and 95% of plantlets were acclimatized to field conditions successfully. Somatic chromosome numbers of mother and in vitro grown plants were confirmed to be 2n = 14. Chromosome length ranged from 4.28 - 13.74 µm in the naturally grown plants and 4.46 - 14.1 µm for in vitro grown plants. The total form percent (TF%) of mother and in vitro grown plants was 41.69% and 42.23%, respectively. The karyotype formula of in vivo grown plants was 2n = 14 = 4Lsm + 6Mm + 4Sm, whereas that of the micropropagated plants was 2n = 14 = 4Lsm + 4Mm + 6Sm. The frequency of the chromosome having arm more than 2:1 was 0.08 for mother plants and 0.15 for in vitro grown plants. Therefore, the karyotype of both plants falls into the 2B symmetrical type based on Stebbins classification (1971).
THROUGHGOING FLUID-CONDUCTING STRUCTURES: CONCEPTUALIZATION, TERMINOLOGY, TYPES, PROPERTIES, AND THE ROLE IN FLUID CIRCULATION
Authors: Klimchouk O.B. 
Published: October 2022

In this paper the review and analysis of global data on throughgoing fluid-conducting structures is performed, the problematic issues of related concepts and terminology are considered, typification of structures by various criteria is proposed and their role in fluid circulation and in lithogenesis and evolution of sedimentary basins is accessed. Such structures are ubiquitous and are an integral part of the drainage system of the upper crust, although the intensity of their distribution and impact on fluid circulation vary widely and increase drastically in certain geological and geodynamic conditions. At the local and subregional scales, throughgoing structures and related phenomena show uneven, clustered distribution.
The key role of throughgoing structures in fluid circulation, including the migration of hydrocarbons and pollutants, is determined by their intersecting and throughgoing nature with respect to layered inhomogeneities, including sealing (low permeability) horizons, and by usually much higher permeability than that of the host rocks. The vertical nature of structures and localized vertical fluid flow across lateral lithological and hydrodynamic boundaries cause the formation of thermal and geochemical anomalies and disequilibrium of the water-rock system, accompanied by the interaction of conduit fluids with host rocks and reservoirs and by alteration of the rocks that contain them. This determines the leading role of throuhgoing structures in superimposed lithogenesis and ore mineralization.
The fluid conductivity of throughgoing structures is variable over time because it depends on their origin, stages of their formation and secondary changes. In this regard, the comparison of this ability between morphogenetic varieties of throughgoing structures is generally difficult, although the most effective in this respect are structures of karstic origin. For structures of fluidodynamic type, the greatest permeability and intensity of fluid flows through the conduits are characteristic of the periods of their formation and immediately after them, as well as of the periods of activation, which are usually associated with tectonic events.
