Published: August 2024

Introduction: An efficient stroke program plays a crucial role in timely diagnosis and management of acute stroke cases. Our hospital has endorsed performance targets for critical steps in the stroke activation and management pathway. This is a quality improvement initiative aimed to identify bottleneck events within the current code stroke pathway that led to delays in image acquisition/interpretation and challenge the achievement of set benchmark times. Methods: We constructed a process map outlining key steps in the code stroke pathway relevant to image acquisition and interpretation, aligning with the stroke target benchmark times. A total of 241 stroke cases documented between 1/1/2022 and 6/1/2022 were reviewed. Activity timestamp was utilized to calculate various time intervals and assess compliance with the specified benchmark times set by our institution’s stroke program. Results: Arrival to stroke activation was the most frequently missed benchmark (miss rate of 45.8%) with wide ranging arrival to code stroke activation time (mean of 18.9±22.2 minutes). The next frequently missed benchmarks were arrival to noncontrast head computed tomography (NCT) read time (miss rate of 25.4%), and arrival to first CT angiogram (CTA) slice acquisition time (miss rate of 21.1%), both set at under 45 minutes. The fourth frequently missed benchmark was observed in order to CTA read time, where 19.0% of cases missed the goal time of under 60 minutes; this benchmark encompasses the time interval between the first NCT slice to the subsequent first CTA slice, a variable time interval under the radiology department’s control that averaged 9.1±18.6 minutes. Conclusions: Although arrival to NCT read time and arrival to first CTA slice acquisition times were among the greatest missed time benchmarks, these were likely secondary to inconsistencies in arrival to code stroke activation time. One of the time intervals in the fourth frequently missed benchmark of order to CTA read time was under departmental control. Addressing and enhancing the consistency of this specific time interval could potentially contribute to an overall improvement in the time interval from ordering the CTA to the CTA being read.

Educational Leadership and Learners’ Academic Achievement in Secondary Schools in Developing Countries: A Critical Review
Authors: Karoli Gervas B.P , Upadhyaya Amar 
Published: August 2024

The study explored three leadership styles in education for students’ academic achievement in secondary schools viz: democratic, laissez-faire and autocratic leadership styles in developing countries. The main crux of the study was examining the impact of heads of schools' leadership towards academic achievement of secondary schools’ students and recommending the most effective leadership style for heads. In-depth study of heads of schools' leadership styles to students’ academic achievement through systematic review of previous related literature was conducted. The study used qualitative method to analyse 49 published documents of which 5 were books published from 2002 to 2023 and 44 were papers published from 2006 to 2023 years. This study was confined in the following sample of countries Nigeria, Ghana, Tanzania, Kenya and South Africa. Also, supplementary papers from Kuwait and USA were reviewed to study more how leadership in education is done. The findings showed that no single leadership style in educational context fits all schools’ environments. Moreover, it was shown that most heads of schools prefer the use of the democratic type of leadership style which does not fit all schools’ environments. The studies revealed that educational situations differ, thus the leadership style chosen should rely on the school situation. The current study recommends some effective measures for leadership development of secondary schools’ heads.

A field experiment with spilt plot design was conducted to study the ‘effect of fertility and silicon levels on the nutritional quality of maize’ during Kharif 2022 and 2023 at Rajasthan College of Agriculture (RCA), MPUAT, Udaipur, Rajasthan, India. The main plot treatments consist of four levels of Compounded NPK fertilizer (F0: Control, F50: 50% RDF, F75: 75% RDF and F100: 100 % RDF) and the sub-plot treatments consist of four levels of soil application of Diatomaceous Earth (Si0, Si100, Si200 and Si300). Pratap Makka-9 of maize variety was used for research purpose. The protein content, protein yield, carbohydrate and energy in maize grain were higher under 100% RDF than other levels of fertilizer. Application of 300 kg Diatomaceous Earth per hectare recorded higher protein content, protein yield, carbohydrate and energy in maize grain over the rest of silicon levels. The crude fat in maize grain was lower in 100% RDF. Application of 300 kg Diatomaceous Earth per hectare recorded lower crude fat in maize grain. Significantly higher protein yield was recorded under the combined application of 100% RDF and 300 kg diatomaceous earth per hectare. However, protein yield was at par in the application of 75% RDF with 300 kg Diatomaceous Earth per hectare and 100% RDF with 200 kg Diatomaceous Earth per hectare. The lowest crude fat was recorded under the combined application of 100% RDF and 300 kg Diatomaceous Earth per hectare over the rest of treatment combinations. Application of 100% RDF with 300 kg DE ha-1 (F100Si300) was recommended treatment for nutritional high quality maize grain.

Published: August 2024

The purpose of the present study was to evaluate the path analysis and D2 analysis on 20 different okra genotypes, including one check variety. The experiment was carried out during the Kharif season of 2023-2024 at Research Farm, College of Agriculture Saralgaon, Murbad, Thane. A randomized block design with three replications was employed for the study. The observations were recorded on thirteen traits viz., days to 50% flowering, plant height (cm), number of branches per plant, number of internodes, internodal length (cm), fruit length (cm), fruit diameter (cm), average fruit weight (gm), no. of fruits per plant, no. of seeds per fruit, seed index (%), and fruit yield per plant (g). The traits with the highest positive direct effect in phenotypic path coefficient analysis were observed for number of fruits per plant. The genotypic path coefficient analysis revealed highest positive direct effect on fruit yield per plant is days to 50% flowering. Thus, these characters need special attention during the time of selection strategy due to their contrasting direct effects. Based on D2 analysis, 20 genotypes were grouped into five clusters. The maximum inter-cluster distance was observed between cluster 5 and cluster 3 indicating that the genotypes falling in these clusters were highly divergent from each other implying a large amount of diversity within and between groups, which could be exploited in breeding programmes. The minimum Inter-cluster distance was found between cluster 5 and cluster 4 indicating that this cluster is less divergent. The cluster means for different characters showed considerable difference among the clusters for all the characters.
Hybrid simulation of the interaction of solar wind protons with a concentrated lunar magnetic anomaly
Authors: Giacalone J. , Hood L. L. 
Published: May 2015

AbstractUsing a two‐dimensional hybrid simulation, we study the physics of the interaction of the solar wind with a localized magnetic field concentration, or “magcon,” on the Moon. Our simulation treats the solar wind protons kinetically and the electrons as a charge‐neutralizing fluid. This approach is necessary because the characteristic scale of the magcon is of the same order or smaller than the proton inertial length—the characteristic scale in the hybrid simulation. Specifically, we consider a case in which the incident solar wind flows exactly normal to the lunar surface, and the magcon is represented by a simple dipole whose moment is parallel to the surface, with a center just below it. We find that while the magcon causes the solar wind to be deflected and decelerated, it does not completely shield the lunar surface anywhere. However, protons which impact the surface in the center of the magnetic anomaly have energies well below the solar wind ram energy. Thus, in this region, any backscattered neutral particles resulting from the interaction of solar wind protons with the lunar regolith would have energies lower than that of the solar wind. Moreover, very few neutrals, if any, would emanate from within the magcon with energies comparable to the solar wind energy. This may explain recent observations of lunar energetic neutral atoms associated with a strong crustal magnetic anomaly. Our study also finds that a significant fraction of the incoming solar wind protons are reflected back into space before reaching the surface. These particles are reflected by a strong electrostatic field which results from the difference in the proton and electron inertia. The reflected particles are seen at very high altitudes above the Moon, over 200 km, and over a much broader spatial scale than the magcon, several hundred kilometers at least. Our simulation also revealed a second population of reflected particles which originate from the side of the magcon where the interplanetary and magcon magnetic fields are directed opposite to one another, leading to a magnetic topology much like magnetic reconnection. As previously reflected particles move through this region, they are deflected upward, away from the surface, forming a second component. Our simulation has a number of similarities to recent in situ spacecraft observations of reflected ions above and around magcons.

AbstractThis study presents the outcome of an inverse modeling intercomparison experiment on the use of total column CO2 retrievals from Greenhouse Gas Observing Satellite (GOSAT) for quantifying global sources and sinks of CO2. Eight research groups submitted inverse modeling results for the first year of GOSAT measurements. Inversions were carried out using only GOSAT data, a combination of GOSAT and surface measurements, and using only surface measurements. As expected, the most robust flux estimates are obtained at large scales (e.g., within 20% of the annual flux at the global scale), and they quickly diverge toward the scale of the subcontinental TRANSCOM regions and beyond (to >100% of the annual flux). We focus our analysis on a shift in the CO2 uptake over land from the Tropics toward the Northern Hemisphere Extra tropics of ∼1 PgC/yr when GOSAT data are used in the inversions. This shift is largely driven by TRANSCOM regions Europe and Northern Africa, showing, respectively, an increased uptake and release of 0.7 and 0.9 PgC/yr. Inversions using GOSAT data show a reduced gradient between midlatitudes of the Northern Hemisphere and the Tropics, consistent with the latitudinal shift in carbon uptake. However, the reduced gradients degrade the agreement with background aircraft and surface measurements. To narrow the range of inversion‐derived flux, estimates will require further efforts to understand the differences not only between the retrieval schemes but also between inverse models, as their contributions to the overall uncertainty are estimated to be of similar magnitude.
Impact of snow darkening via dust, black carbon, and organic carbon on boreal spring climate in the Earth system

Published: May 2015

AbstractDust, black carbon (BC), and organic carbon (OC) aerosols, when deposited onto snow, are known to reduce the albedo of the snow (i.e., snow darkening effect (SDE)). Here using the NASA Goddard Earth Observing System Model, Version 5 (GEOS‐5) with aerosol tracers and a state‐of‐the‐art snow darkening module (GOddard SnoW Impurity Module: GOSWIM) for the land surface, we examine the role of SDE on climate in the boreal spring snowmelt season. SDE is found to produce significant surface warming (over 15 W m−2) over broad areas in midlatitudes, with dust being the most important contributor to the warming in central Asia and the western Himalayas and with BC having larger impact in the Europe, eastern Himalayas, East Asia, and North America. The contribution of OC to the warming is generally low but still significant mainly over southeastern Siberia, northeastern East Asia, and western Canada (~19% of the total solar visible absorption by these snow impurities). The simulations suggest that SDE strengthens the boreal spring water cycle in East Asia through water recycling and moisture advection from the ocean and contributes to the maintenance of dry conditions in parts of a region spanning Europe to central Asia, partially through feedback on the model's background climatology. Overall, our study suggests that the existence of SDE in the Earth system associated with dust, BC, and OC contributes significantly to enhanced surface warming over continents in northern hemisphere midlatitudes during boreal spring, raising the surface skin temperature by approximately 3–6 K near the snowline.
Estimating daily mean land surface albedo from MODIS data

Published: May 2015

AbstractLand surface albedo (LSA) is an important component of the surface radiation budget. For calculation of the surface shortwave net radiation budget, temporal mean albedo is more important than instantaneous albedo. Although Moderate Resolution Imaging Spectroradiometer (MODIS) albedo products have been extensively validated, little effort has been made to evaluate the accuracy of daily mean albedo from MODIS. In this study, we calculate daily mean albedo from MODIS data using a direct method and a look‐up table (LUT) method. Comparison with in situ albedo measured at 27 field stations shows that both methods can estimate daily mean albedo with high accuracy. The root‐mean‐square error (RMSE) of snow‐free daily mean albedo retrieved by the LUT method and the direct method is 0.033 and 0.034, respectively. Over the 12 spatially representative stations, RMSE of daily mean albedo is 0.022 and 0.023 by the LUT and direct approach, respectively. Simply using the local noon albedo value as a surrogate of daily mean albedo leads to overestimation of daily shortwave net radiation. By using the data of daily mean albedo, the bias in estimating daily shortwave net radiation can be reduced by 2.8 W/m2 with the direct method and 2.6 W/m2 with the LUT method, compared to the use of local noon albedo.

AbstractThe ruthenium‐catalyzed dehydrogenative silylation of benzamides with 1,1,1,3,5,5,5‐heptamethyltrisiloxane took place at ortho‐positions of the benzene ring. Several benzamides containing both electron‐donating and electron‐withdrawing groups could be used in this silylation. Density functional theory (DFT) calculations and kinetic isotope effect experiments suggest that the catalytic cycle should involve the CSi bond formation as rate‐determining step.magnified image
Mechanistic Insights into Enantioselective CH Photooxygenation of Aldehydes via Enamine Catalysis
Authors: Walaszek Dominika J. , Rybicka‐Jasińska Katarzyna , Smoleń Sabina , Karczewski Maksymilian , Gryko Dorota 
Published: May 2015

AbstractOrganocatalytic photooxygenation of aldehydes at the α‐position proceeds via enamine catalysis, though enamines should be easily oxidized by singlet oxygen respectively to amides and carbonyl compounds. Moreover, the formation of a zwitterionic enamine peroxide intermediate was postulated based on experimental and theoretical data. The reaction affords desired diols (after in situ reduction) in a decent yield and (S)‐ or (R)‐enantioselectivity depending on a catalyst used. The (S)‐enantiomer predominated in imidazolidinone‐catalyzed reactions, while prolineamides assured the formation of the (R)‐stereoisomer. DFT calculation suggests that the enamine–oxygen complex with the lowest energy has the E, s‐cis conformation for the prolineamide derivative and E, s‐trans for the imidazolidinone catalyst, explaining the opposite stereoselectivity in the photooxygenation reaction.magnified image
