To assist project managers in overcoming or reducing the impact of project risk, several risk management models and standards have been established. This study is aimed to assess the impact of identified IT project risk factors on project delivery (satisfaction) in Qatar’s public sector. A questionnaire consisting of identified risk factors was developed by reviewing related literature. Data were collected from the target sample and analyzed using SPSS and SmartPLS. The results demonstrated the impact of each of the nine identified risk factors with the dependent variable project delivery (satisfaction). The hypotheses analysis showed five hypotheses H1, H2, H5, H6, and H8 supporting the literature with a positive impact on project delivery (satisfaction). Those factors are namely, the Stakeholders, Business Process, Organizational, Technical, and Schedule with significant P-values of 0.030, 0.002, 0.028, 0.023, and 0.001, respectively. The other four hypotheses H3, H4, H7, and H9 are inconsistent with the literature, with (insignificant) high P-values resulting in a negative impact on project delivery (satisfaction). Those factors are namely, Project Management, Human resources, Budget, and External with P-values 0.164, 0.605, 0.096, 0.225, respectively. The researcher recommends that project management professionals consider the five identified risk factors with a positive impact as the most critical IT risk factors; the research findings serve as a foundation and guideline to help the project management community avoid project pitfalls commonly associated with poor risk management and project failure.","PeriodicalId":9295,"journal":{"name":"Building Resilience at Universities: Role of Innovation and Entrepreneurship","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87599819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Every year approximately 40,000 pedestrians are killed in the world due to road traffic crashes. In the state of Qatar, the situations are even worse with around one-third of the total road traffic deaths coming from pedestrians. The main aim of this driving simulator study was to investigate the impact of different measures on driving behavior. To this end, five different treatments were tested and compared with the untreated condition. The treatment conditions included two detection-based measures (i.e., Variable Message Sign VMS and LED), two different road-marking conditions (i.e., Zigzag marking and road narrowing marking) and a physical road narrowing condition. Each condition was tested with a yield/stop controlled marked crosswalk for two situations. In the first situation (Situation PA) there was no pedestrian at the crosswalk, while the second situation was based on the presence of a pedestrian (Situation PP). The experiment was conducted using the driving simulator at Qatar University. Sixty-one volunteers possessing a valid Qatari driving license participated in the study. The collected data was analyzed for drivers’ yielding rates, vehicle-pedestrian interactions, and driving speed. The results showed that the three conditions, i.e., VMS, Narrowing and Physical were effective in improving drivers’ yielding rate up to 98.2%. In addition, we found that all the treatment conditions were effective in reducing drivers’ travel speed in Situation PP. Nevertheless, in the situation with no pedestrian present, the physical road narrowing outperformed the other conditions in terms of reducing travel speed. Taking into account the results from this study, we recommend Physical condition as a potentially effective and low-cost treatment for improving safety at yield/stop controlled crosswalks.","PeriodicalId":9295,"journal":{"name":"Building Resilience at Universities: Role of Innovation and Entrepreneurship","volume":"104 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87739172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These navigation problems appear to arise due to the repetitive similarity of individual parts in its modular design, highly localized impediments to readability and visibility such as shading device screens and temporary installations, and the relationship of those different parts composing the collective whole of the BCR Corridors to the immediate surrounding context of the QU campus (Figure 1). The purpose of the “Complexity and Use in Building Evaluation” research project (CUBE2: QUST-2-CENG-2019-12) is to build on the research success of the post-occupancy cluster in the first demonstration project (CUBE1: QUST-2-CENG-2018-9). It includes continuing to develop a detailed post-occupancy dataset of movement and space use in buildings at QU. The goal is to contribute positively to future design refinements, alterations, and design of new university buildings at QU. We want to help create a world-class center of education and research where space use, interaction, and innovation are tactically ‘woven’ into the design and planning of the campus at various scales of the built environment. In the CUBE1 study, Major et al. (2019) were able to graphically illustrate building program/use and movement/space use patterns. It included quantifying the relationship between movement and spatial layout, and the significance of other end-user activities such as sitting and interacting in the common areas of the QU Women’s Engineering Building. It also included identifying adaptive re-use of classrooms and storage spaces for laboratory and office uses, leading to a shortage of storage spaces in the building. There was a consistent relationship (R^2=0.68, p < 0.001) between sitting and interacting unrelated to accessibility or metric area, i.e., the availability of seating was the dominant factor for casual encounter, mostly of students. Finally, there was a weak but consistent relationship (R^2=0.38, p < 0.001) between spatial layout and movement flows using space syntax modeling when allowing for the strongly programmatic differences (classrooms versus faculty offices) in different wings of the building (Major et al., 2019) (Figure 2). The post-occupancy evaluation findings in the CUBE1 project were largely consistent with previous results of space syntax research over the last 30 years for generative layouts such as office buildings, colleges, and research laboratories. Those results include the generative role of spatial layout for movement and casual encounter in buildings, the prescriptive effects of strong programmatic aspects (in this case, classroom location and course schedules) in causing some spaces to over-perform/underperform for some types of uses, most usually movement, and the singular importance for the provision of seating to facilitate consistent and robust use of spaces whether at the building or urban level (Hillier and Penn, 1991; Hilli","PeriodicalId":9295,"journal":{"name":"Building Resilience at Universities: Role of Innovation and Entrepreneurship","volume":"69 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86144952","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, TKIs are associated with severe cardiotoxicity limiting their clinical benefits. One TKI that has been developed recently but not explored much is Ponatinib. The use of nanoparticles as a better therapeutic agent to deliver anti-cancer drugs and reduce their cardiotoxicity has been recently considered. In this study, PLGA-PEG-PLGA nanoparticles were synthesized to deliver Ponatinib while reducing its cardiotoxicity for treatment of chronic myeloid leukemia. Shape, size, surface charge and drug uptake ability of these nanoparticles were assessed using transmission electron microscopy (TEM), ZetaSIZER NANO and high-performance liquid chromatography (HPLC). Cardiotoxicity of Ponatinib, unloaded and loaded PLGA-PEG-PLGA nanoparticles were studied on zebrafish model through measuring the survival rate and cardiac function parameters, to optimize efficient drug concentrations in an in vivo setting. These particles were tested on zebrafish cancer xenograft model in which, K562 cell line, was transplanted into zebrafish embryos. We showed that, at an optimal concentration (0.0025mg/ml), Ponatinib loaded PLGA-PEG-PLGA particles are non-toxic/non-cardio-toxic and are very efficient against cancer growth and metastasis. Zebrafish is a good animal model for investigating the cardiotoxicity associated with the anti-cancer drugs such as TKIs, to determine the optimum concentration of smart nanoparticles with the least side effects and to generate xenograft model of several cancer types. Also, PLGA-PEG-PLGA NPs could be good candidate for CML treatment, but their cellular internalization should be enhanced. This could be achieved by coating and labeling the surface of PLGA-PEG-PLGA NPs with specific ligands that are unique to CML cells.","PeriodicalId":9295,"journal":{"name":"Building Resilience at Universities: Role of Innovation and Entrepreneurship","volume":"176 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86224409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the presence of an external magnetic field, its mechanical properties, such as stiffness, changes make it attractive in vibration isolation applications. Unwanted vibration in machines can cause severe damage and machine breakdown. In Qatar, the extraction of the natural gas from the ground requires sophisticated drilling machines. In this work, a semi-active vibration isolator using MRE is proposed for a potential application in a drilling system to isolate the torsional vibration. MRE was fabricated with a 35% mass fraction (MF) consisting of silicon rubber and iron particles. It was fitted with aluminum couplers and attached to the shaft (drill string) to study its efficiency in vibration isolation under a magnetic field. Two tests were conducted on the drilling prototype setup used in this work; the first test was a hammer impact test. The torsional transfer function TTF analysis showed that the system's natural frequency has shifted from 13.9 Hz to 17.5 Hz by the influence of increasing magnetic field around the MRE. The results showed that the continuous rotational vibration amplitude of the prototype is attenuated by more than 40%.","PeriodicalId":9295,"journal":{"name":"Building Resilience at Universities: Role of Innovation and Entrepreneurship","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82915640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Increasing investigations report toxicity of certain oxide nanoparticles, however, there are also studies showing opposite results, highlighting the fact that these nanoparticles may differ in their toxicological effects, which depend on particle variety and size, test organism species, and test method. The current study investigates the ecotoxicity of SnO2 nanoparticles on a local marine algae isolate. Five different concentrations (1, 5, 25, 50 and 100mg/L) were tested and the culture was followed for 72h. Algae growth, morphology and metabolites were followed each 24h. The obtained data showed that the SnO2 presented a toxicity on the algae growth that was decreasing with the dose, with lower doses presenting more negative impacts than the higher doses. In parallel, the slow growth observed at 1-5 mg/L was explained by the dramatic damages caused by the SnO2 on the cell morphology, which was detected using the scanning electronic microscopy. Indeed, this low negative impact of higher concentrations of SnO2 (50-100mg/L) is explained by the high agglomeration of ten particles leading to reduced effect on the cell morphology and health. Furthermore, and in accordance with the morphological data, the metabolites analysis data revealed that SnO2 nanoparticles induced stress, which was manifested by an increase in the lipid content and decrease in the proteins, a metabolite that is involved in the algal growth.","PeriodicalId":9295,"journal":{"name":"Building Resilience at Universities: Role of Innovation and Entrepreneurship","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88823456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Leukemia, cancer of the hematopoetic cells is the main cause of cancer death in adults and children. Therapeutic agents used in treatment of cancer are known to have narrow therapeutic window and tendency to develop resistance against some cancer cell lines thus, proposing a need to discover some novel agents to treat cancer. In the present study we investigated the anticancer activity of Neosetophomone B(NSP-B), an aquatic fungal metabolite isolated from Neosetophoma sp against leukemic cells (K562 and U937). MTT results demonstrated a dose dependent inhibition of cell proliferation in K562 and U937 cell lines. Annexin staining using flow cytometry indicated that NSP-B treatment cause a dose dependent apoptosis in leukemic cells.Western blot analysis showed that NSP-B mediated apoptosis involves sequential activation of caspase 9, 3 and poly (ADP-ribose) polymerase (PARP) cleavage. Furthermore NSP-B treatment of leukemic cells resulted in upregulation of pro-apoptotic proteins (Bax) with downregulation of anti-apoptotic proteins ( Bcl-2 ).Thus, present study focuses on exploring the mechanism of anticancer activity of NSP-B on leukemic cells, raising the possibility of its use as a novel therapeutic agent for hematological malignancies. Results: We sought to determine whether NSP-B suppresses the growth of leukemic cell lines. We tested a panel of leukemic cell lines with different doses of NSP-B. Cell viability decreased in a concentration-dependent manner in K562 and U937 cell lines. NSP-B induced apoptosis in K562 and U937 cell lines via downregulation of anti-apoptotic proteins and enhancement of pro-apoptotic proteins. NSP-B induced the activation of caspase cascade signaling pathway. Altogether our results suggest that the NSP-B plays an important role in apoptosis in leukemic cell lines .Conclusions: Our data provides insight on anticancer activities of NSP-B in leukemic cell lines (K562 and U937). NSP-B inhibit cell viability via inducing apoptosis. The NSP-B mediated apoptosis occurs via downregulation of anti-apoptotic proteins and enhancement of pro-apototic proteins, thereby activating the caspase-cascade signaling. Further studies are required to elicit role of NSP-B in regulating molecular pathway involved in the progression of cancer. Taken together, above results suggest that NSP-B may have a future therapeutic role in leukemia and possibly other hematological malignancies.","PeriodicalId":9295,"journal":{"name":"Building Resilience at Universities: Role of Innovation and Entrepreneurship","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80665860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
