Initially presenting with tonic-clonic seizures and headaches, his condition was managed with ceftriaxone and metronidazole. The subsequent drop in neutrophil counts from 7.54 × 10^9/L to 0.87 × 10^9/L leads to the discontinuation of ceftriaxone and the administration of granulocyte-colony stimulating factor (G-CSF), which effectively restored the neutrophil levels. This case highlights that clinicians should be aware of ceftriaxone-induced neutropenia as a potential complication, especially in patients undergoing prolonged therapy. Regular monitoring and timely management are essential for patient safety and favorable outcomes
Blended learning: call of the day for medical education in the global South
No full textBlended learning (BL) is an e-learning approach that combines the strengths of both online and face-to-face learning, creating meaningful interactions between students, teachers, and resources. This paper explores students’ expectations and satisfaction with, and participation in, a basic science course offered through BL approaches in an undergraduate medical education programme in Pakistan. Developmental anatomy (embryology) was redesigned as a BL course and offered to a hundred first-year students. Both online activities and technology-assisted face-to-face interactive discussions were used in each topic. Students’ expectations were gathered at the start of the course and perceptions regarding their satisfaction with the course was collected at the end of the course via questionnaires. A temporal analysis of the website use was conducted to determine any changes in use across the course. The data shows that students were satisfied with their experience in the course. Their expectations regarding technology and pedagogy were met. Online individual learning activities were rated higher than collaborative discussions. Face-to-face discussions received a high rating compared to online learning activities. Students’ access to the website varied throughout the course and declined over time. However, some activity was noted before the exams. Students made extensive use of WhatsApp. In basic science subjects, BL has the potential to offer learners some control over content, learning sequence, and pace and time of learning. Unless made part of an assessment scheme, online discussions and other activities are not likely to be seen as useful learning strategies by students. Teachers’ skills in designing and facilitating BL courses are critical to the success thereof.

Fabry-Perot studies of the Milky Way bar: kinematics, chemical composition and instrumentation
No full textGalactic bars and bulges play an important role in the formation and evolution processes in disk galaxies. There is now substantial evidence that our Galaxy is barred, and many unresolved questions about the structure, dynamics and star formation history of the inner Galaxy remain.
We use Fabry-Perot (FP) absorption line imaging spectroscopy to measure radial velocities using the CaII8542 line in 3360 stars towards three lines of sight in the Milky Way's bar: Baade's Window and offset positions at (l,b) ~ (pm 5.0, -3.5). This sample includes 2488 bar red clump giants, 339 bar M-giants, and 318 disk main sequence stars. We measure the first four
moments of the stellar velocity distribution of the red clump giants, and find it to be symmetric and flat-topped. We detect stellar streams at the near and far side of the bar with velocity difference ~ 30 km/s at l = +/- 5, indicating strong non-circular motions. We do
not detect two separate streams in Baade's Window. Our M-giants kinematics agree well with previous studies, but have dispersions systematically lower than those of the red clump giants by ~10 km/s.
We show that reliable absorption line strengths can also be measured using FP spectroscopy. The
CaII8542 line is a good indicator of metallicity and its calibration to [Fe/H] is determined for globular cluster red giants in previous investigations. We derive such a calibration for the bulge giants and use it to infer metallicities for our red clump sample. We present the stellar metallicity distributions along the major axis of the bar. We find the mean [Fe/H] in Baade's Window close to solar, and the distribution in this field agrees well with previous works. We find negative gradients in the mean metallicity and its dispersion along the bar. We detect a signature of a possible new tidal stream at l = +5.5, in both our velocity and metallicity distributions. We also measure the metallicity of a bulge globular cluster NGC 6522 in our Baade's Window field to be -0.9 dex, in good agreement with previous high-resolution spectroscopic measurements, demonstrating the reliability of our metallicity measurements.
We also present the design and testing of the FP system for the 10-meter class Southern African Large Telescope, and its characterization as measured in the laboratory. It provides spectroscopic imaging at any desired wavelength spanning a bandpass 430 -- 860 nm, at four different spectral resolving powers ranging from 300 to 9000. This FP system will provide a
powerful tool for imaging spectroscopy on one of the world's largest telescopes.Ph.D.Includes bibliographical referencesby Naseem Rangwal
نسیم حجازی کے تاریخی ناول اورفنی تقاضوں کاتجزیہ
No full textThis article comprises the analysis of Naseem Hijazi's art of historical novel writing and its technical attributes. He is reckoned among those great historical novelists who have gained the pinnacle, meeting the technical needs of genre, without tempering the historical facts. Hijazi is a conscious historian and deals the art carefully. For a more realistic portrayal, his characters are original and factual, while keeping the elegance and beauty of style and presentation in view. Naseem Hijazi presents a well-arranged plot, characters, scenes and dialogues with a methodical ingenuity. Cogent reason behind his selection of this particular genre of writing is his intimacy with Islamic literature and deep affiliation with Islam and Muslims. Although some critics argue that Hijazi's style of writing is rhetorical and oratory yet it evinces interest in the readers
On evildoers: A Foucaultian analysis of the discursive structuring of contemporary terrorism
No full textTerrorism is routinely portrayed in the twenty first century as an evil perpetrated by Arab/Muslim barbarians—Evildoers—waging a holy war against the Western civilisation. This study challenges not just this present understanding of terrorism, but the very existence of a ding an sich of terrorism. Using a combination of Foucault’s archaeological and genealogical methods it provides an alternative history of the phenomenon in the form of a history of its discursive structuring: the regimes of practices that governed what could and could not be thought of, identified, defined, known, judged and punished as ‘terrorism’ during particular epochs, and particular places. It asserts that the conceptual anchor point of the present Evildoer-terrorist is the rebel who opposes established order, and identifies the first such figure in modern Western history as the Devil who rebelled against God and came to play a significant politico religious role in Western societies of the Middle Ages. The discourse of ‘terrorism’ emerged from the epistemic spaces created from the separation of religion and politics in the eighteenth century, from when onwards rebellion was no longer a sin but a crime. Since then, various other rebels have been brought under the domain of terrorism during different epochs, the latest of whom is the Evildoer. This is not to say that the Devil remained a blatant constant in the forefront of Western terrorism discourse, but that the various rebels share a conceptual history that made it possible for the contemporary terrorist to be the Evildoer that he is. How the rebels came to be known as terrorists during various epochs and the various mechanisms implemented to defend societies against them, it is argued, are irrevocably linked: one could not exist without the other. The contemporary terrorist cannot be known as an Evildoer without the War on Terror; at the same time, the War on Terror cannot be waged without the knowledge of the terrorist as an Evildoer. To demonstrate this power/knowledge dyad at work, this study analyses what was said and done about terrorism by the United States and the United Kingdom, the foremost allies in the War on Terror, during its first ten years. In the differences in their discourses emerges not just the ontological uncertainty of terrorism but also how these mechanisms for establishing the ‘truth’ of terrorism function as mechanisms of power. It is asserted that the Evildoer has made possible, and was made possible by, some of the most significant changes in how power is exercised in Western societies since the separation of religion and politics in the eighteenth century
A variational framework for multi-scale defect modeling in strained electronics and processing of composite materials
No full textWith the recent advances in material processing technologies and the introduction of the material genome initiative, material processing has gained an increased level of attention in the research community. Primary challenges in most material processing technologies and specifically in composite materials are the uncertainties concerning the material’s performance under loading whether it be static, dynamic or cyclic. That is due to the variabilities in these technologies that may lead to the formation of defects within the material parts at critical location during processing. This dissertation presents a deterministic defect modeling framework based on a system of variationally consistent formulations that allow for the modeling of the material processing stage and incorporate multi-physics coupling for multi-constituent materials. A stabilized and novel discontinuity capturing formulation is developed to model multi-phase flow of the materials and their defect while sharply capturing the jumps in material properties, material compressibility and kinetic reaction across the multi-phase interfaces.
The method is based on employing structured non-moving meshes to solve the Navier-Stokes equations employing a finite element method (FEM) stabilized via the Variational Multiscale Method (VMS). Within VMS framework a discontinuity capturing method is derived that allows for sharp discontinuity capturing of the physical discontinuities of across phases within a single numerical element allowing for highly accurate and discrete representation of the interfacial physical phenomena. In addition, surface tension is incorporated into the formulation to discretely model jumps in the pressure field. The multi-phase interface is evolved employing a stabilized level-set method allowing for intricate motion of the two phases and the discontinuities within the Eulerian mesh. The formulation is then expanded to incorporate discontinuities in the governing system of equations allowing for modeling adjacent compressible-incompressible fluids within a unified formulation. Coupled with the thermal evolution within the constituents of the material and accounting for phase change and mass leading to mass transfer across the interface the materials, kinetic evolution of the material viscosities is modeled at the material points accounting for variability in the flow behavior as a function of kinetic curing. Finally, a previously developed isogeometric FEM method is expanded to model quantum defect evolution of strained electronics and the effect of straining on the electronic properties of these materials.
Representative numerical tests involving complex multi-phase flows of physical instabilities, hydrodynamic collapse of bubbles and convective mass transfer along with electronic band-gap structures with strain effects are presented as validations and applications for the framework’s robustness. Finally, the chemo-thermo-mechanical coupling and real-life application is presented via a fully coupled problem involving processing of a composite bracket during the early curing stages.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2020-12-01The student, Ahmad Al-naseem, accepted the attached license on 2018-12-05 at 18:19.The student, Ahmad Al-naseem, submitted this Dissertation for approval on 2018-12-05 at 18:31.This Dissertation was approved for publication on 2018-12-07 at 08:12.DSpace SAF Submission Ingestion Package generated from Vireo submission #13227 on 2019-02-08 at 11:41:22Made available in DSpace on 2019-02-08T18:44:40Z (GMT).

Designing EthAKUL: a mobile just-in-time learning environment for bioethics in Pakistan
No full textIn developing countries such as Pakistan, bioethics has not been included in mainstream thinking in medical education. The authors’ experiences suggest that current methods of teaching bioethics are problematic as students are unable to translate theory to practice. Alternative pedagogies, such as just-in-time learning (JiTL) using mobile devices, may be able to foster the development and implementation of ethical reasoning among nurses, doctors, and medical and nursing students. This research was conceived to determine the effectiveness of mobile JiTL – anytime, anyplace learning through mobile devices – for teaching bioethics. After obtaining ethical clearance, a participatory design (PD) approach was adopted to ensure input from all stakeholders for the design of ‘EthAKUL’, comprising a mobile app, five modules and just-in-time pedagogy. The name of the app is an acronym evoking ethics, learning and the university where the project originated. As a part of the design process, three PD workshops were held with junior doctors, nurses, nursing students, medical students and bioethics teaching faculty, and five meetings were held with faculty members, to discuss functional specifications and user-acceptance testing of the app. The feedback related to the nature of common ethical issues encountered in clinical settings, the existing process of teaching and learning bioethics, and the requested features of the app were recorded. These data sets were analyzed and synthesized into functional and technical specifications for the mobile app. The software programmers developed the app with the close involvement of the stakeholders. The development of teaching content continued alongside this process. While this enabled EthAKUL’s developers to incorporate needs of all stakeholders, challenges were encountered in the process relating to the pragmatic and conceptual aspects of JiTL, ML and PD. We discuss the implications of this research in bringing about transformative changes in higher education.
