Published: September 2024

The aim of the article is to provide a research result to support the process of consensual and collegiate decision-making in order to mix study models in undergraduate degree courses and postgraduate projects in higher education. The deductive method was used as a starting point and a mixed phenomenological-hermeneutic approach was applied for the methodological design, based on the use of quantitative and qualitative techniques, for which a sample of undergraduate and postgraduate students was selected from the active student population in the year 2021. A structured survey was applied as a technique and a nominal scale was used to collect and analyse the data, which made it possible to determine the students' preferences according to the face-to-face or virtual modality, as well as the incidence of the mixture of both modalities for learning. The results of the research show that undergraduate students show a preference for the face-to-face modality, while postgraduate students prefer the virtual modality. From the examination of the problem, the analysis of the theoretical framework and the applied methodology, it is concluded that the results of the research can help in the process of collegiate decision making by the management agents of higher education institutions, to adequately dose the time load of the face-to-face or virtual modalities, as appropriate to the degree courses and projects.

Published: September 2024

Cadmium (Cd) is one of the most toxic heavy metals. Its high mobility and bioaccumulation power in plant, animal and human tissues differentiate it from the rest of its group and motivate the interest of scientists to know its effects and interaction with plants and the environment. The aim of the present study was to isolate and evaluate the in vitro tolerance of rhizospheric bacteria associated with rice plants in cadmium-contaminated environments and to evaluate them in vitro capacity to tolerate cadmium and the production of compounds related to their ability to remediate and promote plant growth. Rhizospheric bacteria were isolated, tolerance was found up to 500 mg/L CdCl2 and the ability to produce siderophore and solubilize phosphate at this concentration of cadmium was observed in vitro. The morphospecies with the ability to tolerate cadmium up to 500 mg/L found corresponds to Pseudomonas aeruginosa GU270941.1, a species of rhizospheric bacteria that shows an alternative to reduce cadmium uptake by rice plants and promote the growth of these plants for their adaptation and tolerance to this metal.

Brain Metastases from Ovarian Cancer: A Comprehensive Review
Authors: Cui Anna 
Published: September 2024

Ovarian Cancer Ovarian cancer (OC) is the current leading cause of gynecological cancer deaths. Despite its fatal outcome, only 20% of ovarian cancers are detected in the early stage. The reason involves a combination of factors — there is no reliable screening for ovarian cancer, and any symptoms of ovarian cancer tend to be vague and easily ignored. Consequently, OC is given the advantage of metastasizing due to ignorance. However, recently, overall survival from ovarian carcinoma has been reported to increase after improvements in treatment (Siegel et al., 2020). Brain Metastases from OC Central nervous system (CNS) metastasis from epithelial ovarian carcinoma (EOC) is uncommon, with an incidence of brain metastases ranging from 1–3% (Zumrut et al., 2020). Moreover, the treatment of brain metastases from ovarian carcinoma is currently ill-defined because of its rarity and the small affected population. The median survival after diagnosis of brain metastases was six months, meaning BMs mainly occurred while the patient was in stages III or VI of OC. Nevertheless, the median interval between diagnosis of ovarian carcinoma and consequent brain metastases is also quite long, approximately 2 years (Piura et al., 2011). However, neuro-cognition and quality of life across therapies are increasingly recognized as essential endpoints for patients as survival continues to increase. This paper is a comprehensive review of brain metastases from ovarian cancer, investigating tumour proliferation, metastatic mechanisms, the role of BRCA 1/2, and several therapy options, such as PARP inhibitors.
Effect of unproctored versus proctored examinations on student performance and long-term retention of knowledge
Authors: Zhang Niu , Larose James , Franklin Megan 
Published: September 2024

ABSTRACT

Objective
To compare unproctored and proctored online exams among chiropractic students.

Methods
Pre-existing data of 234 students across 4 consecutive endocrinology classes were analyzed for this study. The course was comprised of 3 lectures (50 minutes per lecture) each week. Student performance was evaluated by midterm exam and summative exam (S1). The students from 3 classes were asked to take a voluntary second summative exam (S2) approximately 7 months after the S1. Since this study was partially conducted during the COVID pandemic, some classes took the midterm and the S1 proctored in the classroom while others took them unproctored from a remote location.

Results
The mean midterm exam (p &lt; .001) and S1 scores (p = .01) for the unproctored group (93.6 ± 7.0 and 88.8 ± 8.2) were significantly higher than the proctored group (88.1 ± 8.2 and 83.9 ± 11.2). The mean time taken by students was much greater for the unproctored exams than for the proctored exams (midterm: 40.7 ± 10.2 versus 16.7 ± 7.0, p &lt; .001; S1: 47.0 ± 8.7 versus 21.5 ± 9.0, p &lt; .001). By contrast, the mean unproctored S2 scores were lower than the proctored group (60.2 ± 14.7 versus 88.1 ± 8.2, p &lt; .001). A linear regression test showed that the final exam was a statistically significant predictor of the recall exam (p &lt; .01, R2 = 28.3%).

Conclusion
The findings suggest that student performance is significantly altered by test format.
Warming and weakening trends of the Kuroshio during 1993–2013
Authors: Wang You‐Lin , Wu Chau‐Ron , Chao Shenn‐Yu 
Published: August 2016

AbstractGlobal warming seems leveling off somewhat during 1993–2013 despite increasing atmospheric greenhouse gases. What has happened to the Kuroshio Current system concurrently? Available independent data sets from 1993 to 2013 point to a single answer. Here we show a systemwide weakened Kuroshio during the period despite enhanced warming along its path. The Pacific warm pool upstream of the Kuroshio is still becoming warmer during the period. It injects more heat into the Current despite the weakened Kuroshio, which is associated with weakened westerlies and cyclonic trends of basin‐scale wind stress curl. The weakened Kuroshio will modulate heat and mass exchanges between the tropics and extratropics, impacting the energy balance of climate system. It will also significantly influence mass, heat, salinity, and nutrient exchanges between the Pacific and adjacent marginal seas, which in turn impacts the regional weather, fisheries, and environments.
The 2015 Wolf volcano (Galápagos) eruption studied using Sentinel‐1 and ALOS‐2 data
Authors: Xu Wenbin , Jónsson Sigurjón , Ruch Joël , Aoki Yosuke 
Published: August 2016

AbstractAn energetic eruption started on 25 May 2015 from a circumferential fissure at the summit of Wolf volcano on Isabela Island, western Galápagos. Further eruptive activity within the Wolf caldera followed in mid‐June 2015. As no geodetic observations of earlier eruptions at Wolf exist, this eruption provides an opportunity to study the volcano's magmatic plumbing system for the first time. Here we use interferometric synthetic aperture radar (InSAR) data from both the Sentinel‐1A and ALOS‐2 satellites to map and analyze the surface deformation at four time periods during the activity. These data allow us to identify the two eruption phases and reveal strong coeruptive subsidence within the Wolf caldera that is superimposed on a larger volcano‐wide subsidence signal. Modeling of the surface displacements shows that two shallow magma reservoirs located under Wolf at ~1 km and ~5 km below sea level explain the subsidence and that these reservoirs appear to be hydraulically connected. We also suggest that the transition from the circumferential to the intracaldera eruption may have involved ring fault activity.
Scaling relation between earthquake magnitude and the departure time from P wave similar growth
Authors: Noda Shunta , Ellsworth William L. 
Published: August 2016

AbstractWe introduce a new scaling relation between earthquake magnitude (M) and a characteristic of initial P wave displacement. By examining Japanese K‐NET data averaged in bins partitioned by Mw and hypocentral distance, we demonstrate that the P wave displacement briefly displays similar growth at the onset of rupture and that the departure time (Tdp), which is defined as the time of departure from similarity of the absolute displacement after applying a band‐pass filter, correlates with the final M in a range of 4.5 ≤ Mw ≤ 7. The scaling relation between Mw and Tdp implies that useful information on the final M can be derived while the event is still in progress because Tdp occurs before the completion of rupture. We conclude that the scaling relation is important not only for earthquake early warning but also for the source physics of earthquakes.
Short‐range, overpressure‐driven methane migration in coarse‐grained gas hydrate reservoirs
Authors: Nole Michael , Daigle Hugh , Cook Ann E. , Malinverno Alberto 
Published: August 2016

AbstractTwo methane migration mechanisms have been proposed for coarse‐grained gas hydrate reservoirs: short‐range diffusive gas migration and long‐range advective fluid transport from depth. Herein, we demonstrate that short‐range fluid flow due to overpressure in marine sediments is a significant additional methane transport mechanism that allows hydrate to precipitate in large quantities in thick, coarse‐grained hydrate reservoirs. Two‐dimensional simulations demonstrate that this migration mechanism, short‐range advective transport, can supply significant amounts of dissolved gas and is unencumbered by limitations of the other two end‐member mechanisms. Short‐range advective migration can increase the amount of methane delivered to sands as compared to the slow process of diffusion, yet it is not necessarily limited by effective porosity reduction as is typical of updip advection from a deep source.

Published: August 2016

AbstractStratospheric aerosols cool the Earth by scattering sunlight. Although sulfuric acid dominates the stratospheric aerosol, this study finds that organic material in the lowermost stratosphere contributes 30–40% of the nonvolcanic stratospheric aerosol optical depth (sAOD). Simulations indicate that nonvolcanic sAOD has increased 77% since 1850. Stratospheric aerosol accounts for 21% of the total direct aerosol radiative forcing (which is negative) and 12% of the total aerosol optical depth (AOD) increase from organics and sulfate. There is a larger stratospheric influence on radiative forcing (i.e., 21%) relative to AOD (i.e., 12%) because an increase of tropospheric black carbon warms the planet while stratospheric aerosols (including black carbon) cool the planet. Radiative forcing from nonvolcanic stratospheric aerosol mass of anthropogenic origin, including organics, has not been widely considered as a significant influence on the climate system.
Ceres: Sulfur deposits and graphitized carbon
Authors: Hendrix Amanda R. , Vilas Faith , Li Jian‐Yang 
Published: August 2016

AbstractWe report new results from observations of the dwarf planet Ceres using the Hubble Space Telescope in the spectral range 1160–5700 Å. Comparisons between Ceres' UV‐visible spectra and laboratory measurements indicate that both sulfur species and graphitized carbon are important on Ceres' surface. We find a latitudinal gradient in UV absorption, with northern latitudes being more UV absorbing than southern latitudes, a trend that can be explained by increasing abundances of sulfur and SO2 toward northern latitudes. The presence of graphitized carbon is consistent with the surface of this airless body being carbonized in response to processes such as charged particle bombardment. The presence of volatile sulfur species is consistent with the idea that Ceres exhibits geothermal activity. Spectral differences with previous UV observations are likely due to the changing sulfurous and carbonaceous surface of Ceres.
On a flawed conclusion that the 1255 A.D. earthquake ruptured 800 km of the Himalayan Frontal Thrust east of Kathmandu
Authors: Pierce Ian , Wesnousky Steven G. 
Published: August 2016

AbstractA reexamination of the observations and analysis recently reported to conclude that an 800 km section of the Himalayan Frontal Thrust ruptured in 1255 A.D. shows that the conclusion is flawed and without merit because of misinterpretations of trench logs and incorrect interpretation of radiocarbon statistics.
The suppression of surfzone cross‐shore mixing by alongshore currents
Authors: Spydell Matthew S. 
Published: August 2016

AbstractMixing by horizontal surfzone eddies is important to the cross‐shore exchange of material through the surfzone. Surfzone cross‐shore mixing for normally and obliquely incident waves, with very similar incident significant wave heights and directional spreads, is quantified using Boussinesq modeled drifter trajectories. For t < 100 s, surfzone cross‐shore diffusivities K(t) are independent of incident wave angle
owing to similar eddy velocities
m s−1. For 600 < t < 10,000 s, K(t) is maximum for normally incident waves and decreases with incident wave angle. Thus, the mixing parameterization
is not completely applicable to the surfzone, because
and LE do not change for these experiments. Reduced mixing for obliquely incident waves results from large eddies (wavelengths >200 m) propagating at a velocity C different than the mean current velocity V(x)—the same mechanism that reduces mixing for mesoscale eddies.
Kinematic rupture scenarios and synthetic displacement data: An example application to the Cascadia subduction zone
Authors: Melgar Diego , LeVeque Randall J. , Dreger Douglas S. , Allen Richard M. 
Published: August 2016

AbstractScenario ruptures and ground motion simulation are important tools for studies of expected earthquake and tsunami hazards during future events. This is particularly important for large (Mw8+) and very large (Mw8.5+) events for which observations are still limited. In particular, synthetic waveforms are important to test the response of earthquake and tsunami warning systems to large events. These systems are not often exercised in this manner. We will show an application of the Karhunen‐Loève (K‐L) expansion to generate stochastic slip distributions of large events with an example application to the Cascadia subduction zone. We will discuss how to extend the static slip distributions obtained from the K‐L expansion to produce kinematic rupture models and generate synthetic long‐period displacement data at the sampling rates of traditional Global Navigation Satellite Systems (GNSS) stations. We will validate the waveforms produced by this method by comparison to a displacement‐based ground motion prediction equation obtained from GNSS measurements of large earthquakes worldwide.
Variability of oceanic deep convective system vertical structures observed by CloudSat in Indo‐Pacific regions associated with the Madden‐Julian oscillation
Authors: Yuan Jian 
Published: August 2016

AbstractVertical structures of deep convective systems during the Madden‐Julian oscillation (MJO) are investigated using CloudSat radar measurements in Indo‐Pacific oceanic areas. In active phases of the MJO, relatively more large systems and connected mesoscale convective systems (CMCSs) occur. The occurrence frequency of CMCSs peaks in the onset phase, a phase earlier than separated mesoscale convective systems (SMCSs). Compared with SMCSs, CMCSs of all sizes have weaker reflectivity above 8 km in their deep precipitating portions and thick anvil clouds closely linked to them, suggesting more “stratiform” physics associated with them. SMCSs and CMCSs together produce relatively the least anvil clouds in the onset phase, while their deep precipitating portions show stronger/weaker reflectivity above 8 km before/after the onset phase. Thus, after the onset phase of the MJO, mesoscale convective systems shift toward a more “convective” organization because SMCSs maximize after the onset, while their internal structures appear more stratiform because internally they have weaker reflectivity above 8 km. CMCSs coincide with a more humid middle troposphere spatially, even at the same locations a few days before they occur. Middle‐tropospheric moistening peaks in the onset phase. Moistening of the free troposphere around deep convective systems shows relatively stronger moistening/drying below 700 hPa before/after the onset phase than domain‐mean averages. Low‐topped clouds occur most frequently around CMCSs and in active phases, consistent with the presence of a moister free troposphere. Coexistence of these phenomena suggests that the role of middle troposphere moisture in the formation of CMCSs should be better understood.
