Narratives in Mamluk architecture: Spatial and perceptual analyses of the madrassas and their mausoleums
No full textAbstractMamluk sultans were known for their patronage of the arts and architecture. Their educational institutions were among the wide array of architectural projects that linked them as ruling elites to the religious scholars of their times. Their tombs were placed in a mausoleum attached to their educational–religious complexes to attest to their legacy. The evolution of their buildings such that both educational and memorial functions are integrated with the dense surroundings is scrutinized through chronological–spatial analysis. The configuration of the built form, the disposition of its boundaries, its patterns of accessibility, and its visual properties are the features that present the buildings to one’s experience and bring certain perceptions into play. In this study, various spatial descriptor tools of space syntax are employed to analyze the data of 14 Mamluk examples (1260–1517A.D.) and capture the differences in the experience where the expression is preserved. Analyses of the configurational characteristics, axial attributes, visibility structures, and isovists highlight how the spatial and formal properties of the layouts were used to express certain representational relationships. The advantages of combining different spatial investigations allows for understanding historical design principles and how the geometry of forms could hide in its abstract rules, conceptual and perceptual qualities

Protromic and functional study of Acinetobacter abumannii outer membrane vesicles
No full textThe author has granted permission for their work to be available to the general public.<italic>Acinetobacter baumannii<italic>, a gram-negative aerobic bacterium, is one of the most spread bacteria which can be easily isolated from water, soil, and hospital facilities. It may cause various types of diseases such as respiratory tract infection, urinary tract infection, nosocomial pneumonia and bacteremia. It was noticed that <italic>A. baumanii<italic> was existed in the blood stream of military people deployed in Iraq and Afghanistan who suffered with serious injury. The treatment for the infection of <italic>A. baumannii<italic> is limited because it resists to resist nearly 90% of antibiotics. Therefore, to better treat the infection of <italic>A. baumannii<italic>,the mechanism of infection and virulence factors involved in pathogenecity needed to be studied. Similar to other gram-negative bacteria, outer membrane vesicles (OMVs) secreted by A. baumannii consisted of virulence factors. In my study, the <italic>A. baumannii<italic> OMVs were isolated and observed under transmission electron microscopy. The proteomic analysis indicated that <italic>A. baumannii<italic> OMVs consisted of various virulence factors such as OmpA. To understand the function of the <italic>A. baumannii<italic> OMVs, OMVs were incubated with macrophage cells. Results showed the macrophage cells were lysed when incubated with OMVs compared to cells in the control group which were intact. The quantification of cytotoxicity caused by OMVs showed that the mortality rate reached 80% when 0.02 ug/ml OMVs were added.
In my study, the OMVs were isolated and observed. The virulence factors were identified by proteomic analysis and OMVs are toxic to macrophage cells in vitro.Integrative Biolog

No full textIndividual face-to-face feedback and the Saudi EFL learners: Evaluating enhancement of writing skills
No full text This research analyzed Saudi undergraduate students’ writing before and after individual face-to-face feedback. The intervention was individual written feedback on Saudi EFL students' paragraph writing. The participants were 31 EFL Saudi students exposed to a pre and post-test across six criteria that targeted to evaluate their writing with individual corrective feedback from the teacher. The intervention was one semester long. The study reported that individual corrective feedback plays an important role in developing students' writing skills.
Thirty-one students participated in the writing tasks. All the participants had studied English as a foreign language being enrolled in the writing course at Qassim University College of Language and Translation. The median age of the participants was 20 years and the group was homogenous in terms of years of learning English, residence type (rural/ urban), GPA scores in the past two semesters, and gender (all males). Though the initial group strength was 31, in the post tests, 8 answers were repeated, so the author deleted them from the analysis. Thus, the actual participants were 23 students. The researcher got an oral consent from the students to participate in the study.
The study clearly established that individual face-to-face corrective feedback played an important role in developing students’ paragraph writing skills. </p
