Objective
The use of virtual simulation in nursing education is an effective approach for improving nursing critical thinking and self-learning abilities, but the previous studies were limited to providing the required evidence that supports the association. This study aimed to assess the relationship between virtual simulation and critical thinking disposition and self-directed learning abilities among nursing students.

Methods
This is a descriptive correlational, non-experimental study. It was conducted among 201 third- and fourth-year nursing students at the Academic Institution, Saudi Arabia. A non-probability convenience sampling technique was used to select the participants; then, an online, adapted questionnaire was sent to the participants, the data from which was analyzed by SPSS.

Results
The study findings showed that virtual simulation benefited nursing students. Most participants (56%) agreed that it helped them to think critically, and approximately 27% strongly agreed. It also enhanced their self-directed learning abilities, and the majority of the students agreed that they often review the way nursing practice is conducted. Furthermore, the results showed a significant, positive relationship between virtual simulation and the critical thinking disposition of nursing students (p-value = 0.03; correlation coefficient = 0.65), a strong positive relationship with self-directed learning abilities of nursing students (p-value = 0.004; correlation coefficient = 0.78), and a strong positive relationship between critical thinking disposition with self-directed learning abilities of nursing students (p-value = 0.01; correlation coefficient = 0.72).

Conclusion
There are significant relationships between virtual simulation and the critical thinking disposition and self-directed learning abilities of nursing students. Furthermore, virtual simulation made the students practice critical thinking and self-learning, so, they simulate events and try to seek out and solve the problems.
Pdk3’s role in RANKL-induced osteoclast differentiation: insights from a bone marrow macrophage model
Authors: Zhang Nan , Wang Lingting , Ye Xuxin 
Published: October 2024

Background
Osteoporosis (OP) is a chronic disease characterized by decreased bone mass, loss of skeletal structural integrity and increased susceptibility to fracture. Available studies have shown that the pyruvate dehydrogenase kinase (PDK) family is associated with osteoclastogenesis and bone loss, but the specific role of Pdk3 in bone pathology has not been systematically investigated.

Methods
A cell OP model was established in receptor activator for nuclear factor-κB Ligand (RANKL)-induced bone marrow macrophages (BMMs). Hereafter, the expression levels of Pdk3 and osteoclastogenesis feature genes including nuclear factor of activated T cells 1 (Nfatc1), Cathepsin K (Ctsk), osteoclast associated Ig-like receptor (Oscar) in BMMs-derived osteoclasts were examined based on real-time quantitative PCR and western blotting methods. Further, the phosphorylation of ERK, P65 and JAK/STAT and their correlation was Pdk3 was gauged. In particular, changes in the activity of these signaling pathways were observed by silencing experiments of the Pdk3 gene (using small interfering RNA). Finally, the effects of Pdk3 gene silencing on signaling pathway activity, osteoclastogenesis, and related inflammatory and apoptotic indicators were observed by transfection with PDK3-specific siRNA.

Results
Following RANKL exposure, the levels of Pdk3 and osteoclastogenesis feature genes were all elevated, and a positive correlation between Pdk3 and osteoclastogenesis feature genes was seen. Meanwhile, ERK, P65 and JAK/STAT phosphorylation was increased by RANKL, and Pdk3 was confirmed to be positively correlated with the phosphorylation of ERK, P65 and JAK/STAT. Additionally, in RANKL-exposed osteoclasts, Pdk3 knockdown diminished the phosphorylation of ERK, P65 and JAK/STAT, reduced the expressions of osteoclastogenesis feature genes. Importantly, knockdown of Pdk3 also reduced the expression of inflammatory cytokines and resulted in elevated levels of Bax and Casp3 expression, as well as downregulation of Bcl2 expression.

Conclusion
This study reveals for the first time the role of Pdk3 in RANKL-induced osteoclastogenesis and OP. These findings provide a foundation for future studies on the role of Pdk3 in other bone diseases and provide new ideas for the development of OP therapeutics targeting Pdk3.
Assessment of Adolescents (10-19 years) Well-being in Afghanistan: Analysis Based on Multiple Indicator Cluster Surveys 2022-23
Authors: Cheboi Asseneth Jerotich , Kalanda Boniface Francis 
Published: October 2024

Aim: Adolescents are an increasing proportion of Afghanistan’s population, and adolescence is recognized as a critical stage during which behavioural patterns, risks and challenges that can have lifelong effects on the wellbeing of adolescents. This paper seeks to provide an in-depth exploration of the well-being of adolescents age 10-19 in Afghanistan, a nation marked by complex sociopolitical dynamics and a long decade of conflict.
Methodology: Analysis of adolescent data for individuals age 10-19 from UNICEF Afghanistan Multiple Indicator Cluster Survey 2022-23 datasets, using Statistical Package for the Social Sciences (SPSS).
Results: The challenges confronting adolescents in Afghanistan are manifold, encompassing socio-economic disparities, limited access to education and healthcare, gender inequities, and the ubiquitous threat of violence and displacement. Factors such as widespread poverty, entrenched harmful practices, and disrupted infrastructure exacerbate their vulnerability, impeding their ability to thrive and fulfill their potential. Moreover, the erosion of social support systems and the traumas of conflict exert a profound toll on their mental and emotional well-being, perpetuating cycles of distress and instability. The analysis shows that wealth quintiles and mothers' level of education significantly influenced outcomes for adolescents across areas such as child marriage, child labor, education attainment, access to literacy and ICT skills and mental health.
Conclusion: Adolescents age (10-19) face multi-layered challenges which affects their well-being. A multisectoral approach with a focus on adolescents from low wealth quintiles, and improvement of mothers’ knowledge is imperative to address most of the challenges faced by adolescents in Afghanistan to promote holistic to support fulfillment of their rights and well-being.

The importance of protected cultivation is increasing day by day due to its capability of producing crop all round the year and increase in the crop productivity. This advantage of protected cultivation can be efficiently achieved by adapting the polyhouse cultivation. To obtain the maximum crop productivity inside a polyhouse, it is necessary to understand the variability of microclimate inside it. The present study aims to understand the spatial variability of microclimate inside a naturally ventilated polyhouse installed with fog cooling system during summer season. The main aim of the study is to understand the effect of fogging system in spatial variability of microclimate. For the study, the data of microclimatic parameters were collected daily from April to June at four different time intervals 8.30 AM, 12.30 PM, 4.30 PM and 8.30 PM. The data recorded was then analyzed in Golden Surfer Software to generate contour plots of weekly averages of microclimate parameters. The analysis revealed that the temperature and relative humidity varied across the polyhouse depending upon the wind velocity and its distribution pattern. The light intensity varied based upon the orientation of polyhouse and the position of sun. Carbon dioxide concentration varied based on temperature, light intensity, crop transpiration and respiration. It can be concluded that, inside a naturally ventilated polyhouse, the microclimate varied both spatially and temporally with fogging system also due to wind effect. Thus, having accurate understanding of the microclimate inside a polyhouse helps to maintain optimal conditions for plant growth and thus improve crop yield and productivity.
Observations of wave‐induced pore pressure gradients and bed level response on a surf zone sandbar

Published: June 2017

AbstractHorizontal and vertical pressure gradients may be important physical mechanisms contributing to onshore sediment transport beneath steep, near‐breaking waves in the surf zone. A barred beach was constructed in a large‐scale laboratory wave flume with a fixed profile containing a mobile sediment layer on the crest of the sandbar. Horizontal and vertical pore pressure gradients were obtained by finite differences of measurements from an array of pressure transducers buried within the upper several centimeters of the bed. Colocated observations of erosion depth were made during asymmetric wave trials with wave heights between 0.10 and 0.98 m, consistently resulting in onshore sheet flow sediment transport. The pore pressure gradient vector within the bed exhibited temporal rotations during each wave cycle, directed predominantly upward under the trough and then rapidly rotating onshore and downward as the wavefront passed. The magnitude of the pore pressure gradient during each phase of rotation was correlated with local wave steepness and relative depth. Momentary bed failures as deep as 20 grain diameters were coincident with sharp increases in the onshore‐directed pore pressure gradients, but occurred at horizontal pressure gradients less than theoretical critical values for initiation of the motion for compact beds. An expression combining the effects of both horizontal and vertical pore pressure gradients with bed shear stress and soil stability is used to determine that failure of the bed is initiated at nonnegligible values of both forces.
The impacts of ocean bottom roughness and tidal flow amplitude on abyssal mixing
Authors: Hibiya Toshiyuki , Ijichi Takashi , Robertson Robin 
Published: June 2017

AbstractExisting parameterizations of vertical mixing over a rough ocean bottom neglect the transformation of linear internal waves into quasi‐steady internal lee waves, which occurs when tide‐topography interactions strengthen. In the present study, we perform a series of eikonal calculations to investigate the energy transfers from upward propagating quasi‐steady internal lee waves to dissipation scales through nonlinear interactions with the background Garrett‐Munk internal waves. For a fixed density stratification, the vertical group velocity of the quasi‐steady internal lee wave increases as either the horizontal wave number of the bottom topography or the tidal flow amplitude increases, whereas the life time of the quasi‐steady internal lee wave decreases as the horizontal wave number of the bottom topography increases but is relatively independent of the tidal flow amplitude. Consequently, the resulting bottom‐enhanced vertical mixing extends further upward as the tidal flow amplitude increases, nearly independent of the bottom roughness. We also find a tradeoff between the fraction of energy dissipated at the ocean bottom and the vertical extent of the energy dissipation region above the ocean bottom.
Faulting and off‐axis submarine massive sulfide accumulation at slow spreading mid‐ocean ridges: A numerical modeling perspective

Published: June 2017

AbstractThe potential of mining seafloor massive sulfide deposits for metals such as Cu, Zn, and Au is currently debated. One key challenge is to predict where the largest deposits worth mining might form, which in turn requires understanding the pattern of subseafloor hydrothermal mass and energy transport. Numerical models of heat and fluid flow are applied to illustrate the important role of fault zone properties (permeability and width) in controlling mass accumulation at hydrothermal vents at slow spreading ridges. We combine modeled mass‐flow rates, vent temperatures, and vent field dimensions with the known fluid chemistry at the fault‐controlled Logatchev 1 hydrothermal field of the Mid‐Atlantic Ridge. We predict that the 135 kilotons of SMS at this site (estimated by other studies) can have accumulated with a minimum depositional efficiency of 5% in the known duration of hydrothermal venting (58,200 year age of the deposit). In general, the most productive faults must provide an efficient fluid pathway while at the same time limit cooling due to mixing with entrained cold seawater. This balance is best met by faults that are just wide and permeable enough to control a hydrothermal plume rising through the oceanic crust. Model runs with increased basal heat input, mimicking a heat flow contribution from along‐axis, lead to higher mass fluxes and vent temperatures, capable of significantly higher SMS accumulation rates. Nonsteady state conditions, such as the influence of a cooling magmatic intrusion beneath the fault zone, also can temporarily increase the mass flux while sustaining high vent temperatures.
Spatial and temporal uplift history of South America from calibrated drainage analysis

Published: June 2017

AbstractA multidisciplinary approach is used to analyze the Cenozoic uplift history of South America. Residual depth anomalies of oceanic crust abutting this continent help to determine the pattern of present‐day dynamic topography. Admittance analysis and crustal thickness measurements indicate that the elastic thickness of the Borborema and Altiplano regions is
km with evidence for sub‐plate support at longer wavelengths. A drainage inventory of 1827 river profiles is assembled and used to investigate landscape development. Linear inverse modeling enables river profiles to be fitted as a function of the spatial and temporal history of regional uplift. Erosional parameters are calibrated using observations from the Borborema Plateau and tested against continent‐wide stratigraphic and thermochronologic constraints. Our results predict that two phases of regional uplift of the Altiplano plateau occurred in Neogene times. Regional uplift of the southern Patagonian Andes also appears to have occurred in Early Miocene times. The consistency between observed and predicted histories for the Borborema, Altiplano, and Patagonian plateaux implies that drainage networks record coherent signals that are amenable to simple modeling strategies. Finally, the predicted pattern of incision across the Amazon catchment constrains solid sedimentary flux at the Foz do Amazonas. Observed and calculated flux estimates match, suggesting that erosion and deposition were triggered by regional Andean uplift during Miocene times.
Receiver function and gravity constraints on crustal structure and vertical movements of the Upper Mississippi Embayment and Ozark Uplift

Published: June 2017

AbstractThe Upper Mississippi Embayment (UME), where the seismically active New Madrid Seismic Zone resides, experienced two phases of subsidence commencing in the Late Precambrian and Cretaceous, respectively. To provide new constraints on models proposed for the mechanisms responsible for the subsidence, we computed and stacked P‐to‐S receiver functions recorded by 49 USArray and other seismic stations located in the UME and the adjacent Ozark Uplift and modeled Bouguer gravity anomaly data. The inferred thickness, density, and Vp/Vs of the upper and lower crustal layers suggest that the UME is characterized by a mafic and high‐density upper crustal layer of ∼30 km thickness, which is underlain by a higher‐density lower crustal layer of up to ∼15 km. Those measurements, in the background of previously published geological observations on the subsidence and uplift history of the UME, are in agreement with the model that the Cretaceous subsidence, which was suggested to be preceded by an approximately 2 km uplift, was the consequence of the passage of a previously proposed thermal plume. The thermoelastic effects of the plume would have induced wide‐spread intrusion of mafic mantle material into the weak UME crust fractured by Precambrian rifting and increased its density, resulting in renewed subsidence after the thermal source was removed. In contrast, the Ozark Uplift has crustal density, thickness, and Vp/Vs measurements that are comparable to those observed on cratonic areas, suggesting an overall normal crust without significant modification by the proposed plume, probably owing to the relatively strong and thick lithosphere.
Observation of Tropical Cyclone‐Induced Shallow Water Currents in Taiwan Strait

Published: June 2017

AbstractThe data from three stations equipped with Acoustic Doppler Current Profilers (ADCPs) deployed in the shallow water of the Taiwan Strait (TWS) were used to study the shallow coastal ocean response to five quasi‐continuous tropical cyclone (TC) events in the late summer 2006. We revealed that, in the forced stage, when the large and strong TC (Bilis) transited, the geostrophic currents were formed which dominated the whole event, while the strong but relatively small one (Saomai) or the weak one (Bopha) primarily leaded to the generation of Ekman currents. In the relaxation stage, the barotropic subinertial waves and/or the baroclinic near‐inertial oscillations (NIOs) were triggered. Typically, during the transit of the Saomai, subinertial waves were induced which demonstrated a period of 2.8–4.1 days and a mean alongshore phase velocity of 14.9 ± 3.2 m/s in the form of free‐barotropic continental shelf waves. However, the NIOs are only notable in the area in which the water column is stably stratified and also where the wind stress is dominated by the clockwise component and accompanied by high‐frequency (near‐inertial) variations. We also demonstrated that, due to the damping effects, the nonlinear wave‐wave interaction (e.g., between NIO and semidiurnal tide in our case), together with the well‐known bottom friction, led to the rapid decay of the observed TC‐induced near‐inertial currents, giving a typical e‐folding time scale of 1–3 inertial periods. Moreover, such nonlinear wave‐wave interaction was even found to play a major role during the spring tide in TWS.
Formation of sea ice bridges in narrow straits in response to wind and water stresses

Published: June 2017

AbstractIce bridges are rigid structures composed of sea ice that form seasonally in the many straits and channels of the Canadian Arctic Archipelago. Driven primarily by atmospheric stresses, these ice bridges are formed when sufficiently thick ice “jams” during the course of its flow between land masses, resulting in a region of stationary compacted ice that is separated from a region of flowing open water (a polynya) by a static arch. Using a continuum description of sea ice that is widely used in climate modeling, we present an asymptotic theory of the process of formation of such bridges in slender channels when the motion of the ice is driven by external wind and water stresses. We show that for an arbitrary channel shape, ice bridges can only form within a range of ice properties that is determined by the channel geometry and the external stress. We then compare the results of our theory with direct numerical simulations and observational evidence. Finally, we provide simple analytical expressions for the mean velocity of the ice flow as a function of the channel shape, the properties of the ice, and the wind and water stresses along the channel.
The non–storm time corrugated upper thermosphere: What is beyond MSIS?
Authors: Liu Huixin , Thayer Jeff , Zhang Yongliang , Lee Woo Kyoung 
Published: June 2017

AbstractObservations in the recent decade have revealed many thermospheric density corrugations/perturbations under nonstorm conditions (Kp < 2). They are generally not captured by empirical models like Mass Spectrometer Incoherent Scatter (MSIS) but are operationally important for long‐term orbital evolution of Low Earth Orbiting satellites and theoretically for coupling processes in the atmosphere‐ionosphere system. We review these density corrugations by classifying them into three types which are driven respectively by the lower atmosphere, ionosphere, and solar wind/magnetosphere. Model capabilities in capturing these features are discussed. A summary table of these corrugations is included to provide a quick guide on their magnitudes, occurring latitude, local time, and season.
