description: Postoperative nausea and vomiting (PONV) is a common complication following surgery, and may be one of the most distressing parts of the surgical journey. With combination pharmacological therapy recommended for PONV prophylaxis, this systematic review and meta-analysis evaluates whether perioperative palonosetron and dexamethasone is more efficacious than palonosetron administered alone. We searched CENTRAL; EMBASE; CINAHL; Google Scholar; Web of Science citation index; the US clinical trials register; UK clinical trials register; Australia and New Zealand Clinical trials register; and conference abstracts for major anaesthesia conferences in the last three years. We included randomized controlled trials that compared adult patients undergoing surgery who received palonosetron and dexamethasone, against those who received palonosetron. A total of 12 studies (1152 patients) were included. Medium-grade evidence showed that the palonosetron and dexamethasone combination significantly reduced 24-hour rescue anti-emetic requirement (RR: 0.59, 95% confidence interval (CI): 0.41–0.86). There was however no significant difference in the 6-hour (RR: 0.82, 95% CI: 0.61–1.09) and 24-hour PONV incidences (RR: 0.60, 95% CI: 0.33–1.10). Similarly, PONV incidences after 24 h did not differ between groups (RR:0.82, 95% CI: 0.59–1.14). Headache and dizziness were the most common side-effects reported. Combination prophylaxis with palonosetron and dexamethasone reduces post-operative anti-emetic requirement, although is not associated with a significant difference in PONV. There was considerable heterogeneity in the studies, and trial sequential analysis indicates that further studies are needed to strengthen the clinical evidence.

description: The Nambu - Bogoliubov - de Gennes method is applied to the problem of superconducting QCD. The effective quark-quark interaction is described within the framework of the Nambu - Jona-Lasinio model. The details of the phase diagram are given as a function of the strength of the quark-quark coupling constant $G^{\prime}$. It is find that there is no superconducting phase transition when one uses the relation between the coupling constants $G^{\prime}$ and $G$ of the Nambu - Jona-Lasinio model which follows from the Fierz transformation. However, for other values of $G^{\prime}$ one can find a rich phase structure containing both the chiral and the superconducting phase transitions.

description: Bound states in the continuum (BICs) and exceptional points (EPs) have been the subjects of recent intensive research as they exhibit exotic phenomena that are significant for both fundamental physics and practical applications. We investigated the emergence of the Friedrich-Wintgen (FW) type BIC and the EP in a dielectric waveguide comprising a metal grating, focusing on their dependence on the grating thickness. The BIC emerges at a branch near the anti-crossing formed of the two waveguide modes, for a grating of any thickness. With the grating-thickness change, the anti-crossing gap varies and the branch at which the BIC appears flips. We show that, when the slit is single mode, the BIC appears at the crossing between the two waveguide modes in the empty-lattice (zero slit-width) limit, while the results satisfy the criteria for the branch at which the BIC appears in the previous reports. In addition, we find that the EP appears near the BIC in the same device only on selecting the grating thickness. The BIC and EP in the dielectric waveguide comprising a metal grating, particularly with such tunability, are expected to result in the development of functional and high-performance photonic devices in addition to being a platform for the fundamental research of non-Hermitian systems.

description: Efficient and versatile spin-to-charge current conversion is crucial for the development of spintronic applications, which strongly rely on the ability to electrically generate and detect spin currents. In this context, the spin Hall effect has been widely studied in heavy metals with strong spin-orbit coupling. While the high crystal symmetry in these materials limits the conversion to the orthogonal configuration, unusual configurations are expected in low symmetry transition metal dichalcogenide semimetals, which could add flexibility to the electrical injection and detection of pure spin currents. Here, we report the observation of spin-to-charge conversion in MoTe$_2$ flakes, which are stacked in graphene lateral spin valves. We detect two distinct contributions arising from the conversion of two different spin orientations. In addition to the conventional conversion where the spin polarization is orthogonal to the charge current, we also detect a conversion where the spin polarization and the charge current are parallel. Both contributions, which could arise either from bulk spin Hall effect or surface Edelstein effect, show large efficiencies comparable to the best spin Hall metals and topological insulators. Our finding enables the simultaneous conversion of spin currents with any in-plane spin polarization in one single experimental configuration.

description: Nowadays, it is no more needed to do an enormous effort to distribute a lot of forms to thousands of people and collect them, then convert this from into electronic format to track people opinion about some subjects. A lot of web sites can today reach a large spectrum with less effort. The majority of web sites suggest to their visitors to leave backups about their feeling of the site or events. So, this makes for us a lot of data which need powerful mean to exploit. Opinion mining in the web becomes more and more an attracting task, due the increasing need for individuals and societies to track the mood of people against several subjects of daily life (sports, politics, television,...). A lot of works in opinion mining was developed in western languages especially English, such works in Arabic language still very scarce. In this paper, we propose our approach, for opinion mining in Arabic Algerian news paper.

description: We study the energy budget of a first-order cosmological phase transition, which is an important factor in the prediction of the resulting gravitational wave spectrum. Formerly, this analysis was based mostly on simplified models as for example the bag equation of state. Here, we present a model-independent approach that is exact up to the temperature dependence of the speed of sound in the broken phase. We find that the only relevant quantities that enter in the hydrodynamic analysis are the speed of sound in the broken phase and a linear combination of the energy and pressure differences between the two phases which we call pseudotrace (normalized to the enthalpy in the broken phase). The pseudotrace quantifies the strength of the phase transition and yields the conventional trace of the energy-momentum tensor for a relativistic plasma (with speed of sound squared of one third). We study this approach in several realistic models of the phase transition and also provide a code snippet that can be used to determine the efficiency coefficient for a given phase transition strength and speed of sound. It turns out that our approach is accurate to the percent level for moderately strong phase transitions, while former approaches give at best the right order of magnitude.

It is found that, the intrinsic nonlinearity of the Riccati type quantum Hamilton-Jacobi equation is primarily responsible for the surprisingly large number of allowed solvability conditions in the associated Lam{é} case. We also study the singularity structure of the quantum momentum function, which yields the band edge eigenvalues and eigenfunctions.

description: Sexual behaviour encompasses actions motivated by sexual desire, whether directed towards individuals of the opposite sex or the same sex. The manifestations of this behavior are quite varied, including feelings of attraction, dating, physical intimacy, and sexual intercourse. This investigation seeks to explore the potential connections between peer influence, social media usage, and sexual behavior in the city of Bukittinggi. This investigation employs quantitative approaches utilizing analytical techniques within a cross-sectional framework. The participants in this study consisted of students from Bukittinggi City, amounting to a total sample of 93 students. This study was carried out in Bukittinggi City. The methodology employed in this study involved the application of probability sampling techniques, specifically utilizing a simple random sampling approach. The tool employed for the study was a questionnaire. The analysis conducted involved both univariate and bivariate approaches, utilizing the chi-square test for evaluation. The findings indicated that a significant portion of participants reported elevated peer influence (40.9%), substantial engagement with social media (43.0%), and a majority exhibited non-risky sexual behavior (57.0%). The findings indicate a significant relationship between peers and sexual behaviour in Bukittinggi City, evidenced by a P-value of 0.0001. Additionally, there is a notable relationship between social media use and sexual behaviour in the same city, also with a P-value of 0.0001.

description: The flavor-changing neutral current decay processes of the $B$ and $B_c$ mesons with the final states involving spin-$1/2$ particles are investigated. By considering the background of the Standard Model where $ν\barν$ contributes the missing energy and the experimental upper bounds for the branching fractions, we get the constraints of the coupling constants of the quark-antiquark and the assumed invisible particles $χ\barχ$. The constraints of the coupling constants are then used to study the similar processes of the $B_c$ meson. At some specific region of $m_χ$, the upper limit of BR($B_c\to D_{(s)}χ\barχ$) is of the order of $10^{-6}$, while for BR($B_c\to D^\ast_{(s)}χ\barχ$), it is $10^{-5}$. The possibility of distinguishing $χ$ to be a Majorana or Dirac fermion by the differential branching fractions is also discussed.

description: Nowadays, hospital wastewater contains a high concentration of toxic pharmaceutical contaminants, posing a significant threat to the environment, and human and animal life. Cefixime (CFX) is one such toxic contaminant that has a detrimental impact on both aquatic and terrestrial ecosystems. Therefore, it is essential to remove this compound using non-toxic and environmentally friendly procedures to ensure healthy drinking water. In this study, a low-cost and eco-friendly nano adsorbent (nZVI/copper slag) was synthesized and characterized using FESEM, XRD, EDX, FTIR, and zeta potential to remove CFX from wastewater. The Response Surface Methodology (RSM) was used to evaluate the effects of experimental factors including adsorbent dosage (2–10 g/L), pollutant concentration (10–30 mg/L), pH (2–10), and contact time (10–50 min) for efficient CFX elimination. The optimal conditions (adsorbent dosage: 7.79 g/L, pollutant concentration: 19.42 mg/L, pH: 4.59, and reaction time: 36.17 min) resulted in 98.71% CFX removal. The adsorption isotherm and kinetics data showed that the pseudo-second-order kinetics and Langmuir isotherm models were appropriate for CFX elimination. Furthermore, the nano adsorbent demonstrated 90% CFX elimination after up to six repeated cycles in regeneration and reusability testing. Finally, the nZVI/CS nano adsorbent can be an effective and promising solution for removing CFX from wastewater.

description: Rapid prototyping technology or 3D printing technology has been applied in maxillofacial surgeries from the end of 1980s. The application solved the demand of making the 'digital internal structure imprint' of head-and-neck anatomy, especially the hard tissue, such as bone structure, from the dental 3D CBCT/ MSCT imaging data. In the beginning of 2000s, HCMC University of Technology (HCMUT) run a 5 - yeared - project, collaborated with the medical cranio-plasty professionals and specialists of the local leading hospitals in HCMC (Ho Chi Minh City, VIetnam), such as Cho Ray Hospital, Gia Dinh People's hospital and Hospital No. 115, which had been used in cranial reconstruction surgeries with SLA technology support, led by Associate Professor Dang Van Nghin (HCMUT). However, the full workflow/ protocols of rapid prototyping application in maxillofacial surgeries was firstly started from 2011. In Vietnam, that application was firstly used and developed as one of major pre-surgery treatment protocols for pre-fabricated jaws prostheses in maxillofacial surgeries, in HCMC National Hospital of Odonto - Stomatology (HCMC NHOS), for the maxillofacial deformities and trauma. To setup the stability of that application, the team of maxillofacial surgeons, maxillofacial prosthestic technicians and supportive engineering technologists have continously done a long-term close, mutual and multi-disciplinary collaboration for more 6 years. This review will present a overview of rapid prototyping application in maxillofacial surgeries in Vietnam, from 2010 to 2016, as the manufacturing engineer's view.

description: A sound stimulus entering the inner ear excites a deformation of the basilar membrane which travels along the cochlea towards the apex. It is well established that this wave-like disturbance is amplified by an active system. Recently, it has been proposed that the active system consists of a set of self-tuned critical oscillators which automatically operate at an oscillatory instability. Here, we show how the concepts of a traveling wave and of self-tuned critical oscillators can be combined to describe the nonlinear wave in the cochlea.

description: We use a suite of $N$-body simulations to study intrinsic alignments (IA) of halo shapes with the surrounding large-scale structure in the $Λ$CDM model. For this purpose, we develop a novel method to measure multipole moments of the three-dimensional power spectrum of the $E$-mode field of halo shapes with the matter/halo distribution, $P_{δE}^{(\ell)}(k)$ (or $P^{(\ell)}_{{\rm h}E}$), and those of the auto-power spectrum of the $E$ mode, $P^{(\ell)}_{EE}(k)$, based on the $E$/$B$-mode decomposition. The IA power spectra have non-vanishing amplitudes over the linear to nonlinear scales, and the large-scale amplitudes at $k\lesssim 0.1~h~{\rm Mpc}^{-1}$ are related to the matter power spectrum via a constant coefficient ($A_{\rm IA}$), similar to the linear bias parameter of galaxy or halo density field. We find that the cross- and auto-power spectra $P_{δE}$ and $P_{EE}$ at nonlinear scales, $k\gtrsim 0.1~h~{\rm Mpc}^{-1}$, show different $k$-dependences relative to the matter power spectrum, suggesting a violation of the nonlinear alignment model commonly used to model contaminations of cosmic shear signals. The IA power spectra exhibit baryon acoustic oscillations, and vary with halo samples of different masses, redshifts and cosmological parameters ($Ω_{\rm m}, S_8$). The cumulative signal-to-noise ratio for the IA power spectra is about 60% of that for the halo density power spectrum, where the super-sample covariance is found to give a significant contribution to the total covariance. Thus our results demonstrate that the IA power spectra of galaxy shapes, measured from imaging and spectroscopic surveys for an overlapping area of the sky, can be used to probe the underlying matter power spectrum, the primordial curvature perturbations, and cosmological parameters, in addition to the standard galaxy density power spectrum.

description: The signals of the neutral top-pion $π^{0}_{t}$ at the first muon collider (FMC) are discussed by calculating its contributions to the processes $μ^{+}μ^{-}\longrightarrow b\bar{b}$ and $μ^{+}μ^{-}\longrightarrow \bar{t}c$. We find that the contributions to the process $μ^{+}μ^{-}\longrightarrow b\bar{b}$ are very small and the ratio of signal over square root of the background ($S/\sqrt{B})$ is smaller than 0.2. However, in most of the parameter space, the $π^{0}_{t}$ can generate 36 and up to 649 observable $\bar{t}c$ events at the FMC. The signals of the neutral top-pion $π^{0}_{t}$ may be detected via the process $μ^{+}μ^{-}\longrightarrow \bar{t}c$ at the FMC.

description: Data sharing has become an increasing important issue facing scientists in recent years.nbsp; And, understanding what kinds of factors affect data sharing behavior remains an important goal in informing those setting data sharing policy. The present analysis examines survey data ICPSR collected from social scientists in the United States who collected primary research data under funding from the National Science Foundation or the National Institutes of Health. Building on our prior work, here we examine whether certain social science disciplines embraced data sharing more than others early on. Results from multivariate regression models suggest political scientists and economists are most likely to share their data and psychologists and health scientists are the least likely. Implications for discipline-specific policies are discussed.

description: We surveyed and presented the state-of-the-art VC systems, security and privacy architectures and technologies, emphasizing on security and privacy challenges and their solutions for P2P interactions in VSNs towards standardization and deployment. We note that beyond safety applications that have drawn a lot of attention in VC systems, there is significant and rising interest in vehicle-to-vehicle interaction for a range of transportation efficiency and infotainment applications, notably LBS as well as a gamut of services by mobile providers. While this enriches the VC systems and the user experience, security and privacy concerns are also intensified. This is especially so, considering (i) the privacy risk from the exposure of the users to the service providers, and (ii) the security risk from the interaction with malicious or selfish and thus misbehaving users or infrastructure. We showed existing solutions can in fact evolve and address the VSN-specific challenges, and improve or even accelerate the adoption of VSN applications.

description: As of late 2014, 20 percent of UK Higher Education Institutions (HEIs) have adopted a Research Data Policy. In contrast, only one percent of German HEIs have adopted one. We examine policies in the context of national funder requirement differences and the overall research funding landscape.nbsp; Whereas recommendations exist on what should go into a policy, there is no analysis on what is going into policies. This presentation compares the content of policies from both countries for similarities and differences to see if -- regardless of the differences in the environments -- a standard form and language is emerging. The presentation will illustrate the adoption of two distinct approaches. The first is a 'general principles' approach. This policy is short, strong on the normative values for data re-use and preservation, and general goals, but weak on policy detail and enforcement mechanisms. The other approach is a formal "legalistic" style; it's longer, specific in requirements, strong in definitions, but not necessarily clear in direction or easy for researchers to work with. Policies are tested for type of university (research intensive vs non-research intensive institutions) and age (university cohort). The results of this research fed into LSE's own draft research data policy.
A unification of the Holstein polaron and dynamic disorder pictures of charge transport in organic semiconductors

description: We present a unified and nonperturbative method for calculating spectral and transport properties of Hamiltonians with simultaneous Holstein (diagonal) and Peierls (off-diagonal) electron-phonon coupling. Our approach is motivated by the separation of energy scales in semiconducting organic molecular cystals, in which electrons couple to high-frequency intramolecular Holstein modes and to low-frequency intermolecular Peierls modes. We treat Peierls modes as quasi-classical dynamic disorder, while Holstein modes are included with a Lang-Firsov polaron transformation and no narrow-band approximation. Our method reduces to the popular polaron picture due to Holstein coupling and the dynamic disorder picture due to Peierls coupling. We derive an expression for efficient numerical evaluation of the frequency-resolved optical conductivity based on the Kubo formula and obtain the DC mobility from its zero-frequency component. We also use our method to calculate the electron-addition Green's function corresponding to the inverse photoemission spectrum. For realistic parameters, temperature-dependent DC mobility is largely determined by the Peierls-induced dynamic disorder with minor quantitative corrections due to polaronic band-narrowing, and an activated regime is not observed at relevant temperatures. In contrast, for frequency-resolved observables, a quantum mechanical treatment of the Holstein coupling is qualitatively important for capturing the phonon replica satellite structure.

description: In this paper, we focus on the localization of a passive source from time difference of arrival (TDOA) measurements. TDOA values are computed with respect to pairs of fixed sensors that are required to be accurately time-synchronized. This constitutes a weakness as all synchronization techniques are vulnerable to delay injections. Attackers are able either to spoof the signal or to inject asymmetric delays in the communication channel. By nature, TDOA measurements are highly sensitive to time-synchronization offsets between sensors. Our first contribution is to show that timing attacks can severely affect the localization process. With a delay of a few microseconds injected on one sensor, the resulting estimate might be several kilometers away from the true location of the unknown source. We also show that residual analysis does not enable the detection and identification of timing attacks. Our second contribution is to propose a two-step TDOA-localization technique that is robust against timing attacks. It uses a known source to define a weight for each pair of sensors, reflecting the confidence in their time synchronization. Our solution then uses the weighted least-squares estimator with the newly created weights and the TDOA measurements received from the unknown source. As a result, our method either identifies the network as being too corrupt to localize, or gives a corrected estimate of the unknown position along with a confidence metric. Numerical results illustrate the performance of our technique.

description: The surface resistance (Rs) and the real part (sigma_1) of the microwave complex conductivity of a ~380 nm-thick polycrystalline MgB2 film with the critical temperature (Tc) of 39.3 K were investigated at ~8.5 GHz as a function of temperature. Two coherence peaks were observed in the sigma_1 versus temperature curve at temperatures of ~0.5 Tc and ~0.9 Tc, respectively, providing a direct evidence for the two-gap nature of MgB2. The film appeared to have a pi-band gap energy of 1.8 meV. For the MgB2 film ion-milled down to the thickness of ~320 nm, two coherence peaks were still observed with the first conductivity peak at ~0.6 Tc. Reduction of Tc by 3 K and reduced normal-state conductivity at Tc were observed along with an enhanced pi-band gap energy of 2.1 meV and a reduced Rs at temperatures below 15 K for the ion-milled film. Calculations based on the gap energies from the weak coupling Bardeen-Cooper-Schrieffer theory and the strong coupling theory suggest that both the sigma-band and the pi-band contribute to sigma_1 of the polycrystalline MgB2 films significantly. Our results are in contrast with the observation of single coherence peak at ~0.6 Tc and dominant role of the pi-band in the microwave conductivity of c-axis oriented MgB2 films as reported by Jin et al. [Phys. Rev. Lett. 91, 127006 (2003)]. Variations in the inter-band coupling constants with the level of disorder can account for the different Tc and sigma_1 behavior for the as-grown and ion-milled films. Our results suggest that enhanced inter-band scattering can improve microwave properties of MgB2 filims at low temperatures due to the larger pi-band gap despite the reduction of Tc.

description: Recent results of two interesting classes of supersymmetric two-loop contributions to (g-2)_mu are presented. Two-loop diagrams involving a closed sfermion loop can amount to 5*10^{-10} or almost one standard deviation of the current experimental uncertainty, and two-loop diagrams with a closed chargino/neutralino loop can be similarly large. The dependence of these two classes on the unknown supersymmetric parameters and the sensitivity on existing experimental constraints on the parameter space are quite different. We also comment on the calculational techniques, in particular the large mass expansion and the treatment of gamma_5 and the epsilon-tensor.

description: In this essay the ontological structure of reality is explored. The question of reducibility of biology to physics is considered in the context of their ultimate principles. It is shown that biology is an ontologically autonomous science and is based on its own, independent ultimate principle that is independent from that of physics. In the next step it is shown that self-consciousness represents a separate realm with its own, ontologically autonomous, ultimate principle. Understanding that reality is based on ultimate principles, a new possibility arises to interpret the origin of physical laws.

description: The giant gamma-ray flares of the Crab nebula discovered by AGILE and Fermi observatories came as a surprise and have challenged the existing models of pulsar wind nebulae. We have carried out an analysis of 10.5 years of Fermi-LAT observations (Aug 2008 -- Feb 2019) and investigated variability of the Crab nebula in the 100-300 MeV range. Besides the flares, we found several month long depressions of the gamma-ray flux and identified several cases of sharp flux drops, where during one week the flux decreased by an order of magnitude with respect to its average value. No statistically significant variations of the nebula flux in the $E>$10 GeV range were found in the data. We discuss possible implications of the observed gamma-ray flux depressions on the model of synchrotron emission of the Crab nebula.

On Covidiots and Covexperts: Stupidity and the Politics of Health

description: The COVID-19 pandemic has highlighted the significance of the politics of health as an ongoing interpretative event. The effectiveness of delivering prevention strategies is in negotiation with day-to-day arguments in the public sphere, not just by “experts” in peer-reviewed papers, but also in the everyday interpretations and discussions of available expertise on print and digital media platforms. In this paper I explore ae particular facet of these public debate over the politics of health: the deployment of the commonplace of stupidity. I argue that the growth of this commonplace within discussion is rooted in particular models of interpretation which limit self-understanding, by over-emphasising certain points of significance within the interpretative horizon over more banal (and “stupid”) aspects that are, nevertheless, influential on health interventions.

[un]Settled : a Pilgrimage to Resettled Landscapes

Publisher: name: The University of British Columbia

description: [un]Settled: a Pilgrimage to Resettled Landscapes investigates the story of settlement and the Newfoundland Resettlement Program through themes of place, identity, and heritage preservation. Drawing on theories of tangible and intangible cultural heritage, sense of place, and fragile architecture, this thesis investigates how architecture can contribute to the resilience of Newfoundland’s sense of place and cultural identity, by reconnecting locals and visitors to the natural landscape and cultural traditions. Through the reinterpretation of vernacular architecture, and the story of resettlement using visual representation techniques, conceptual programmatic typologies emerge. A case is made for an Outport Pilgrimage that travels through Bonavista Bay, and stops in the focused site of Flat Island, in which the design of temporal, ephemeral, and migratory installations will allow for the sharing of intangible cultural heritage.

description: Transmitting unknown quantum states to distant locations is crucial for distributed quantum information protocols. The seminal quantum teleportation scheme achieves this feat while requiring prior maximal entanglement between the sender and receiver. In scenarios with noisy entangled states, optimal teleportation fidelity characterizes the efficacy of transmitting the state, demanding the proper selection of local operations at the sender's and receiver's ends. The complexity escalates further in long-range communication setups, prompting the consideration of a repeater-based approach, which incorporates arrays of nodes with multiple segments to facilitate the efficient transmission of quantum information. The fidelity of the communication line gets degraded even if a single segment is affected by noise. In such cases, the general wisdom employs the standard entanglement swapping protocol involving maximally entangled states across the noiseless segments and applying maximally entangled basis measurement at the corresponding nodes to achieve optimal fidelity. In this Letter, we propose a more efficient protocol for a certain class of noisy states in any intermediary segment, achieving the same fidelity as the standard protocol while consuming less amount of entanglement. Our approach ensures enhanced teleportation fidelity even when the end-to-end state gets noisier, and thus promises efficient utility of quantum resources in repeater-based distributed quantum protocols.

The Makerere University Institutional Repository: Benefits, Challenges and Way Forward

description: Universities function as focal points for academic research in Africa. Egwunyenga (2008) has attributed this to the fact that research is compulsory for lecturers and post graduate students by job description and mandatory academic requirement respectively. The nature of studies at Makerere University requires students to actively engage in research activities in partial fulfilment of the requirements of the degree being sought.nbsp; For academic staff, the concept of "publish or perish" has come to secure their promotion within the academic environment. Consequently, it is expected that, the volume of research output originating from the university addressing local problems in Uganda will continue to increase.nbsp; The research outputs addressing issues endemic to the region should be given wide circulation so that the results can be applied in addressing the issues that they sought to tackle. Unfortunately, these outputs gather dusts in departmental offices and library shelves without getting published (Gideon, 2008).nbsp; Subsequently, these findings die at the institutional level as those in need of this knowledge cannot access it due to institutional and external challenges associated with the Institutional Repository thus the need for an investigation into the practical benefits, challenges andnbsp; propose strategies for improvement.
