EXPERIMENTAL ANALYSIS OF AIR FLOW PROFILES IN A DOUBLE SKIN FAÇADE IN A MARITIME CLIMATE

Glazed Double Skin Facades (DSF) offer the potential to improve the performance of all-glass building skins, common to commercial office buildings in which full facade glazing has almost become the standard. Single skin glazing results in increased heating and cooling costs over opaque walls, due to lower thermal resistance of glass, and the increased impact of solar gain through it. However, the performance benefit of DSF technology continues to be questioned and its operation poorly understood, particularly the nature of airflow through the cavity. This paper deals specifically with the experimental analysis of the air flow characteristics in an automated double skin facade. The benefit of the DSF as a thermal buffer, and to limit overheating is evaluated through analysis of an extensive set of parameters including air and surface temperatures at each level in the DSF, airflow readings in the cavity and at the inlet and outlet, solar and wind data, and analytically derived pressure differentials. The temperature and air-flow are monitored in the cavity of a DSF using wireless sensors and hot wire anemometers respectively. Automated louvre operation and building set-points are monitored via the BMS. Thermal stratification and air flow variation during changing weather conditions are shown to effect the performance of the DSF considerably and hence the energy performance of the building. The relative pressure effects due to buoyancy and wind are analysed and quantified. This research aims to developed and validate models of DSFs in the maritime climate, using multi-season data from experimental monitoring. This extensive experimental study provides data for training and validation of models.
Is there a ‘theory of learning’ for Cultural Studies and is it (still) relevant in an era of surveillance capitalism?

ABSTRACT This article questions how cultural studies has been constructed as an educational project to examine if it might offer principles for learning about living in digital culture now. It first considers how the subject of Cultural Studies developed in relationship to education and then revisits empirical studies of cultural studies in schools. The essay engages with perspectives on evaluating the effects of these approaches and situates debates about learning with reference to theories of resistance and the field of reception studies. The final section of the article explores what cultural studies could and should be doing nowadays amidst considerable concern about the politics of digital culture. It challenges whether some of the underlying educational principles which animated its origins have any value in contemporary concerns with forms of surveillance capitalism.
EFFECT OF GENOTYPES, PLANT POPULATION AND NITROGEN FERTILIZER LEVEL FOR THE NEW SUPERIOR LINE OF COWPEA

This work was carried out at Sakha Agricultural Research Station, during the summer seasons of 2004 and 2005 on cowpea. The main objective of this research was to evaluate three cultivars (Kaha-1, Kafr El-Sheikh-1 and Dokki-331) and new superior line (A7) of cowpea under three nitrogen fertilizer levels (15, 30 and 45 kg N fed.) and two plant populations (60.000 and 120.000 plant fed.). A split-split plot in a randomized complete blocks design with four replicates was used. Results are summarized as follow: Dokki-331 cv. surpassed the other genotypes in plant height, number of leaves plant, number of branches plant and leaf area plant. However Kaha-1 cv. produced the lowest values of vegetative traits in both seasons. The Kafr El-Sheikh-1 cv. surpassed in number of peduncle of pods plant in both seasons. Moreover, seed yield and its components, i.e., seed yield fed, number of pods plant, number of seeds per pod and weight of 100-seeds, the lien A7 surpassed the other genotypes followed by Kafr El-Sheikh-1 cv. However, Dokki-331 cv. produced the lowest seed yield and yield components in both seasons. In addition, the lien A7 surpassed in leaf's chlorophyll and seed's protein content. Less plant density improved vegetative growth characters, as well as yield components and increased leaf contents of chlorophyll and seed content of protein. While, seed yield were increased as a sequence of increasing plant population in both seasons. The results indicated that increasing applied N rate up to 45 kg N fed. -1 was accompanied with significant increases in vegetative growth characters, meanwhile, increased number of peduncle of pods plant with the application of 30 kg N feddan. Moreover, seed yield and its components were increased as a sequence of increasing N level up to 45 kg N fed. , also, leaf's chlorophyll and seed's protein content positively and significantly reflected.
COVID-19 ONLINE CROSS-TRAINING PROGRAM

Background:The need for continuity in medical education with the advent of COVID -19, has been highlighted in light of the current global pandemic situation. As the risks posed by COVID -19 must be balanced against the need to care for patients and protect health care workers, cross-training of various health care professions is now more important than ever. In response to the global pandemic and in line with current practice, the Ministry of National Security, King Abdul-Aziz Medical City-Jeddah, has established a cross-training working task force comprising medical educational specialists from various specialtiesto develop an educational platform that includes up-to-date learning resources to provide healthcare professionals with the knowledge they need to treat critical, suspected, and confirmed COVID -19 patients.The main objective of this manuscript is to describe and discuss the implementation process of the cross-training modules. In addition, the manuscript aims to address the knowledge gap related to COVID -19 management by measuring the perceptions of medical students and healthcare professionals. Methods:A qualitative, descriptive study was conducted in the King Abdul-Aziz Medical City (KAMC) National Guard using the COVID -19 cross-training e-learning platform. The training participants were primarily physicians, then health care workers, students and interns from different universities (KSAU-HS) to be able to treat COVID -19 patients in different areas. This platform was equipped with all the necessary functions to create e-learning training courses. The content of the educational material was to be delivered using two main teaching methods: (1) Virtual learning modules consisting of basic and advanced courses. (2) Simulation-based instruction, consisting of computer-based and simulation manikin-based courses. First, a needs assessment survey was distributed to approximately 150 medical students and health professionals. Then, another self-assessment survey was distributed to approximately 1000 participants. Results: In the needs assessment survey, the majority of participants (22.3%) were from the Department of Internal Medicine. In the feedback survey, the majority of participants were from the Department of Nursing (15.7%). Overall, participants consider the Cross-Training Module/Unit Content & Structure to be adequate in terms of its purpose (P 0.908) results also indicate that participants are satisfied with the provisions (P 0.374) and that the Cross-Training was relevant and helpful to the circumscribed and included professions (P 0.731). Conclusion: As synthesis research, this study revealed the perceptions of health professionals and medical students regarding the implementation of an e-learning strategy for cross-training as a teaching tool. Participants indicated that the training program was most helpful because the course materials were strongly tailored to their areas of expertise.
Characterization of Two-Phase Flow from Pore-Scale Imaging Using Fractal Geometry under Water-Wet and Mixed-Wet Conditions

High resolution micro-computed tomography images for multiphase flow provide us an effective tool to understand the mechanism of fluid flow in porous media, which is not only fundamental to the understanding of macroscopic measurements but also for providing benchmark datasets to validate pore-scale modeling. In this study, we start from two datasets of pore scale imaging of two-phase flow obtained experimentally under in situ imaging conditions at different water fractional flows under water-wet and mixed-wet conditions. Then, fractal dimension, lacunarity and succolarity are used to quantify the complexity, clustering and flow capacity of water and oil phases. The results show that with the wettability of rock surface altered from water-wet to mixed-wet, the fractal dimension for the water phase increases while for the oil phase, it decreases obviously at low water saturation. Lacunarity largely depends on the degree of wettability alteration. The more uniform wetting surfaces are distributed, the more homogeneous the fluid configuration is, which indicates smaller values for lacunarity. Moreover, succolarity is shown to well characterize the wettability effect on flow capacity. The succolarity of the oil phase in the water-wet case is larger than that in the mixed-wet case while for the water phase, the succolarity value in the water-wet is small compared with that in the mixed-wet, which show a similar trend with relative permeability curves for water-wet and mixed-wet. Our study provides a perspective into the influence that phase geometry has on relative permeability under controlled wettability and the resulting phase fractal changes under different saturations that occur during multiphase flow, which allows a means to understand phase geometric changes that occur during fluid flow.

Formulation of roselle extract water-in-oil nanoemulsion for controlled pulmonary delivery

Abstract The anthocyanin (ACN)-rich roselle extract has the potential to inhibit lung cancer. However, the compounds demonstrate low bioavailability and stability in biological applications. The present study proposed a stable formulation of a water-in-oil (w/o) roselle extract nanoemulsion by combining low (hot temperature inversion) and high-energy approaches (ultrasonication and ultra-homogenization) for pulmonary delivery. The stable w/o formulation comprised of roselle extract (0.04 w/w%), sodium chloride solution (3.0 w/w%), medium-chain triglyceride (81.9 w/w%), surfactant (Tween 80 and Span 80) (15.0 w/w%), hydrophilic-lipophilic balance (HLB) of 6.7 [Tween 80/Span 80 (22.5:77.5)] to yield the stable nanoemulsion.The best nanoemulsion showed an average 298 nm particle size, polydispersity index of 0.6, and zeta potential of −49.0 mV. The emulsions were stable in the centrifuge- and freeze-thaw cycle tests,-alongside the 60-days storage tests at 4 °C, 25 °C, and 35 °C. The in-vitro release of the roselle extract at pH 6.5 buffer was 44.7% and 40.7% at pH 7.4 (p > 0.05), with the release patterns following the non-Fickian diffusion. Hence, the present study successfully developed a stable w/o roselle extract nanoemulsion with a relatively moderate release rate of the ACNs, supporting its suitability as a nanocarrier for pulmonary delivery.

Barriers to Safety Event Reporting for Nurses at Beni-Suef University Hospital, Beni-Suef, Egypt

Patient safety and medical errors are one of the major challenges that health systems in all countries are grappling with to minimize and reduce the damage caused by them. An organizational culture of safety affects employees‟ attitudes, beliefs, perceptions, and values related to safe practice as well as their behaviors and level of engagement. The objective of the current study was to determine the barriers for nurses‟ reporting of medical errors. This was an exploratory descriptive qualitative study, conducted from March 2020 to July 2020 in the all departments and intensive care units (ICUs) in Beni-Suef University Hospital. In-depth interviews were held with twelve nurses. When barriers to error reporting were examined, the three areas identified from the data were: (The nurses‟ perceptions of error, Fear and, Barriers related to the system). This work may provide a road map for just culture implementation. Future qualitative and quantitative research should explore effects of just culture on safety reporting patterns and specific events such reducing medication errors or risk-taking behaviors.
Improving Earliness-Related Traits of Egyptian Local Okra Cultivar (Abelmoschus esculentus L. Moench)

This study aimed to improve the local okra cultivar (cv. Balady) by accessing superior earliness pure lines using an individual plant selection breeding program. Six cycles of individual plant selection were carried out at the Agricultural Experimental Station Farm at Abies region, Faculty of Agriculture, Alexandria University, Egypt, which resulted in ten pure lines with distinct horticultural traits. The selected pure lines were evaluated in the summer season of 2020 with the original population. The results showed that the pure lines L5 and L1 recorded significantly the lowest mean values compared to all the genotypes for the earliness traits, viz., days number to first flower and pod, as well as days number to 50% flowering, and days number to first harvest. Moreover, the selected pure lines significantly exceeded the original population in the characteristics of early and total yield per plant, and the three pure lines L4, L8, and L9 were the most distinguished for these traits. Concerning correlation estimates, the characteristics of earliness reflected positive and significant correlations between one another, as well as, with the characteristics plant height and early yield as the number of pods. The results of cluster analysis illustrated that the first group (I) was distinguished as being the earliest, while the third (III) and fourth (IV) clusters were the best for the productivity traits. So, it is recommended to use the pure lines L4, L8, and L9 to improve total and early yield as well as the earliness traits.
Negativity bias in the diagnosticity of online review content: the effects of consumers’ prior experience and need for cognition

ABSTRACT The importance of online review valence is a subject of debate among scholars. Prior studies mostly assumed valence as a “peripheral” cue derived from online review surface features (e.g., star ratings). This assumption has important implications as it restricts the negativity bias effects to a certain group of consumers who lack pertinent prior experience with the product/service domain and the motivation to assess the product/service. Focusing on online service context and drawing on an adaptational view to negative information, we investigate the negativity bias in the effects of the valence of the “content” of online reviews on consumers’ attitudes and show that it can be attributed to the higher perceived diagnosticity of negative reviews. This is determined by consumers’ in-depth elaborations of reviews’ contents, which are contingent on their prior experience with the domain of online service and need for cognition. Our findings provide a new perspective to negativity bias by showing that more experienced and thoughtful consumers are also influenced by negativity bias when the content of online reviews is considered. This is a novel account of negativity bias in the effects of online reviews that underscores the importance of response strategies for reducing their adverse effects.

Conditional paths to business unit agility: corporate IT platforms and the moderating role of business unit IT autonomy

ABSTRACT Agility has long been recognised as a key determinant of organisational performance. The pursuit of agility within business units (BUs) is challenging as IT executives in multi-business organisations (MBOs) are tasked with balancing a need for organisation-wide IT synergies against a desire among BUs for local IT solutions that enable agility in their end markets. MBOs are increasingly turning to corporate IT platforms to respond to their BUs’ IT needs but doing so presents a challenge to BU IT autonomy and, in turn, to BU agility. In this paper, we posit that BU agility is determined by resource synergies based on the interplay between corporate IT platforms and local, BU-controlled, IT applications. These applications lead to greater BU process digitisation and, in turn, to expanded BU agility. We evaluate our model using data from an international survey of IT executives in MBOs. Our findings provide support for our model and, in so doing, identify different paths that MBOs can take to enhance BU agility. Our contribution affirms the value of corporate IT platforms for BU agility but suggests that MBOs should tread carefully when developing corporate IT platforms that coincide with mandatory use of shared IT applications.
