Generalizations of no k-equal spaces
No full textWe consider generalizations of no -equal spaces as well as their relations to other concepts. For any topological space , the no -equal space of is the space of points from such that no are the same. First, we consider a generalization where each of the points is assigned one of colors; the interactions between various points are governed by a subset of . We call these spaces polychromatic configuration spaces. We find the homology groups and cohomology rings for two classes of polychromatic configuration spaces of .
Next, we consider the relation between no -equal spaces of and -trees of simplicial complexes. It was noticed that the first non-trivial homology group of the no -equal space of has rank equal to the number of facets in a -dimensional spanning tree of the -dimensional hypercube. We give a proof of this that is not reliant on knowledge of these numbers. Furthemore, we prove the analogous fact for a generalization of no -equal spaces: comb no -equal spaces.
The -equal arrangements are a generalization of the braid arrangements. In another direction, Manin and Schectman defined discriminantal arrangements as a generalization of braid arrangements. In the final chapter, we combine these two to define codimension- discriminantal arrangements. These arise geometrically as no -intersecting translates of hyperplanes. We give results on the first two non-trivial homology groups of no -intersecting translates of hyperplanes in .Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2020-05-01The student, Nicholas Kosar, accepted the attached license on 2018-04-07 at 12:04.The student, Nicholas Kosar, submitted this Dissertation for approval on 2018-04-07 at 12:05.This Dissertation was approved for publication on 2018-04-10 at 08:04.DSpace SAF Submission Ingestion Package generated from Vireo submission #12146 on 2018-08-31 at 17:18:16Made available in DSpace on 2018-09-04T20:33:59Z (GMT).

Characteristics of Active Tuberculosis Patients Requiring Intensive Care Monitoring and Factors Affecting Mortality
No full textBackground: One to three percent of cases of acute tuberculosis (TB) require monitoring in the intensive care unit (ICU). The purpose of this study is to establish and determine the mortality rate and discuss the causes of high mortality in these cases, and to evaluate the clinical and laboratory findings of TB patients admitted to the pulmonary ICU. Methods: The data of patients admitted to the ICU of Yedikule Chest Diseases and Chest Surgery Education and Research Hospital due to active TB were retrospectively evaluated. Demographic characteristics, medical history, and clinical and laboratory findings were evaluated. Results: Thirty-five TB patients (27 males) with a median age 0117 years were included, of whom 20 died within 30 days (57%). The Acute Physiology and Chronic Health Evaluation 11 (APACHE II) and Sequential Organ Failure Assessment (SOFA) scores were significantly higher, and albumin and PaO2/FIO2 levels were significantly lower, and shock, multiple organ failure, the need for invasive mechanical ventilation and drug resistance were more common in the patients who died. The mortality risk was 7.58 times higher in the patients requiring invasive mechanical ventilation. The SOFA score alone was a significant risk factor affecting surviVal Conclusion: The survival rate is low in cases of tuberculosis treated in an ICU. The predictors of mortality include the requirement of invasive mechanical ventilation and multiple organ failure. :Another factor specific to rt B patients is the presence of drug resistance, which should be taken seriously in countries where there is a high incidence of the disease. Finding new variables that can be established with new prospective studies may help to decrease the high mortalit\ rate
MAPPING THE INTELLECTUAL STRUCTURE OF MIDDLE EASTERN STUDIES: AN AUTHOR CO-CITATION ANALYSIS
No full textThe focus of my dissertation is on Middle Eastern Studies (MES) as produced in English from the mid-20th century onward. The historians of MES talk about a post-Saidian divide in the field between academic-left and -right. When examining this divide, the common practice has mainly been to focus on how political developments affected MES. This work analytically transcends the political surface and ask whether the two clusters can be observed in the mapping of MES. It then explores the properties of this intellectual map, and asks how, in the overly political field of MES, ‘the social’ and ‘the cognitive’ aspects of knowledge production interact.
To map MES this work uses Author Co-Citation Analysis (based on the relative frequencies with which pairs of authors are cited together by citing documents). The research population comprises 202 influential scholars who have produced knowledge in English about the cotemporary period or recent history of the ME. Google Scholar was used as the source of citation data, and the node attributes, along with the scholars’ political and paradigmatic tendencies, were collected from their online profiles.
The map shows no indication of a polarization in the field but shows differences between insider and outsider inquiries and verifies the local situatedness of the process of knowledge production. The network hints towards the presence of at least three clusters, but not along the lines of the scholars’ political and paradigmatic tendencies. Knowledge about the ME as whole is produced in a cooperative endeavor among scholars with different geographical connections, but in the case of Israel and Turkey, the clusters are more homogeneous. The intellectual map also points towards the silenced voices: those who are strongly associated with Iran and Arab countries and shows how geopolitically hegemonic sites of knowledge production act as barriers against the formation of an in-between discursive space.ThesisDoctor of Philosophy (PhD)The focus of my dissertation is on knowledge production: Middle Eastern Studies (MES) as produced in English from the mid 20th century onward. This dissertation uses the clusters of influential MES scholars to ask whether the there is an academic left-right separation the network and whether the personal backgrounds of scholars’ co-citations (based on the relative frequencies with which pairs of authors are cited together by citing documents) explain the clustering.
The co-citation network hints towards the presence of three clusters, but not along the lines of scholars’ political tendencies. Knowledge about the ME as whole is produced by scholars with different personal and academic backgrounds, but the Turkish and Israeli studies clusters are more homogeneous. Other subfields, such as Iranian or Arab studies, are not large enough to draw any definite conclusion, but scholars with stronger associations to Iran and Arab countries are mostly absent in the network
Multiple endobronchial lipomas which were treated by bronchoscopical resection
No full textSummaryBronchial benign tumors are very rare; however, endobronchial lipomas are responsible for 0.1–0.5% of all lung tumors (1,2). Clinical symptoms depend on the severity of bronchial obstruction and the effects on parenchyma. It is more common in men and more frequently observed in the right bronchial system (3). We present a 76-year-old woman with two separate endobronchial lipomas in the upper lobe and intermediary bronchi, who applied with cough and sputum. The patient was successfully treated with electrocautery snare technique. After this procedure, thorax CT showed bronchiectasis of right lower zone. Thoracotomy was not taken into consideration. After 2-year follow-up the patient has no complaint

Coupling high-rate activated sludge process with aerobic granular sludge process for sustainable municipal wastewater treatment
No full textAchieving a neutral/positive energy balance without compromising discharge standards is one of the main goals of wastewater treatment plants (WWTPs) in terms of sustainability. Aerobic granular sludge (AGS) technology promises high treatment performance with low energy and footprint requirement. In this study, high-rate activated sludge (HRAS) process was coupled to AGS process as an energy-efficient pre-treatment option in order to increase energy recovery from municipal wastewater and decrease the particulate matter load of AGS process. Three different feeding strategies were applied throughout the study. AGS system was fed with raw municipal wastewater, with the effluent of HRAS process, and with the mixture of the effluent of HRAS process and raw municipal wastewater at Stage 1, Stage 2 and Stage 3, respectively. Total suspended solids (TSS), chemical oxygen demand (COD), ammonia nitrogen (NH4+-N), and total phosphorus (TP) concentrations in the effluent were less than 10 mg/L, 60 mg/L, 0.4 mg/L, and 1.3 mg/L respectively at all stages. Fluctuations were observed in the denitrification performance due to changes in the influent COD/total nitrogen (TN) ratio. This study showed that coupling HRAS process with AGS process by feeding the AGS process with the mixture of HRAS process effluent and raw municipal wastewater could be an appropriate option for both increasing the energy recovery potential of WWTPs and enabling high effluent quality.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.BT/Environmental Biotechnolog
