Julia-Kocienski Approach To 4-Substituted 1- Alkenyl-1h-1,2,3-Triazoles, Kunga Tsetan

Dissertations and Theses

A modular approach to the synthesis of 4-substituted N-vinyltriazoles was
developed. The triazole cores were assembled by copper-catalyzed 1,3-dipolar
cycloaddition of 1-phenyl-1H-tetrazol-5-yl (PT) azidomethyl sulfide with: pmethoxyphenyl, 2-pyridyl, and triisopropylsilyl alkynes. Subsequent oxidation of the sulfides furnished 4-substituted triazoles with a Julia-Kocienski olefination handle attached at the N1 atom of the triazole. Olefination reactions of triazole-derived Julia-Kocienski reagents with paraformaldehyde gave 1-ethenyl-1H-1,2,3-triazoles. Heck reactions of these products with phenyl or p-methoxyphenyl iodide led to further functionalization of the terminal carbon, with E/Z-olefin ratios ≥ 92%. Heck reaction with p-cyanophenyl iodide gave low conversion, and that with 2-thienyl iodide did not …

Health, Education And Children’S Rights: A Comparability Analysis Of Kenya And Brazil, Charlette Lopez

Dissertations and Theses

Developing adequate health care and education systems has been an ongoing struggle for the governments of both Kenya and Brazil. Despite moderate improvements in health and education statistics for both of these countries, there is clear evidence that these states will have to be actively engaged in order to overcome the challenges that lie ahead. Kenya and Brazil may differ in geographical location, history, culture, and socioeconomic status, but both countries are congruent in the challenges they face to provide sufficient access to quality health care and educational resources to the upcoming generations of children who are being failed by …

Assessing The Utility Of Imaging Radar For Identifying White Sand Vegetation Structure, Jessica Rosenqvist

Dissertations and Theses

White sand vegetation communities are wide spread across South America; found in Peru, Venezuela, Brazilian Amazon and Guyana. They are distributed in patches ranging from <1 km2 to greater than tens of square kilometers and their origins and locations are still not well understood. The communities are related to a variety of factors (soil type, flooding, nutrient content and fire); hence a precise definition for the ecosystem is still not fully defined. Nevertheless, the result of these variations creates a unique environment for endemic plant and animal species to thrive. Furthermore, analysis of these areas has been very scattered and identification of local white sand areas (<1 km2) have not been accomplished. In addition, identification of these locations has currently only used optical satellite imagery (Landsat, MODIS). Hence, in this project, we have attempted to use synthetic aperture radar to create a classification system to locate the white sand vegetation systems. The goal is to be able to apply this method to identify white sand vegetation distribution across South America. The region of focus for this thesis has been in Aracá, a large white sand area located in Brazil in the State of Amazonas. Due to the lack of ground reference data, a classified map by Capurucho et al. (2013), generated using Landsat data, was used as a comparison and reference. JAXA’s ALOS-1 PALSAR (L-band), ESA’s Sentinel-1A (C-band) and NASA’s SRTM sensors were used for land classification. As microwave signals penetrate clouds and haze, the advantage of using sensors with this wavelength allows for an unobstructed coverage of the landscape all year round. Different combinations of polarizations and wavelengths were used during the analysis to try and separate the white sand vegetation from water and terra firme forest. The resulting classification images showed a 30% agreement with the classification map by Capurucho et al. It is important to note, that this number is in fact an agreement percentage as the map used was a classification image and coarse in resolution (due to the lack of reference data). Therefore, this value does not imply a bad classification. Future work will include time-series data, precise ground reference points and data from other sensors such as ALOS-2 PALSAR, to improve the classification accuracy.

The Relationship Between Childhood Trauma And Paranoid Personality Disorder Symptoms, Ayse Arikan

Dissertations and Theses

Background: Recent literature consistently shows a relationship between childhood trauma (CT) and personality pathology. History of childhood abuse leads to severe loss of trust. This loss of trust in early years is a strong predictor of the majority of personality disorders and is related to several problems in adulthood such as insecure attachment and distrust in interpersonal relationships. Although distrust is the key diagnostic component of Paranoid PD (PPD), empirical research mostly focused on borderline personality disorder (BPD) yielding limited information about PPD regarding its development and potential risk factors. This study has two aims. First is to examine the …

An Approach To Automatic Detection Of Suspicious Individuals In A Crowd, Satabdi Mukherjee

Dissertations and Theses

This paper describes an approach to identify individuals with suspicious objects in a crowd. It is based on a well-known image retrieval problem as applied to mobile visual search. In many cases, the process of building a hierarchical tree uses k-means clustering followed by geometric verification. However, the number of clusters is not known in advance, and sometimes it is randomly generated. This may lead to a congested clustering which can cause problems in grouping large real-time data. To overcome this problem we have applied the Indian Buffet stochastic process approach in this paper to the clustering problem. We present …

Technetium: Productivity Tracking For Version Control Systems, David Leonard

Dissertations and Theses

In recent years, the City College of New York has seen its Computer Science program grow immensely, to the point of overcrowding. This has negative implications for both students and professors, particularly in introductory computer science courses in which constant feedback, iteration and collaboration with others is key to success. In this paper we propose various models for collaboration among students in all course levels using distributed version control systems and implement a secure and efficient tool for visualizing collaborative efforts by observing past work [5]. Lastly, we lay the foundation for future work around additional collaborative metrics, features and …

Discrete Model For Cancer Tumor Growth And Effect Of Chemotherapy, Karim Virani

Dissertations and Theses

Many mathematical models have focused on growth of a single tumor with their spreading rate with some have included its metastasis. Some of the earlier models focus on exponential growth and its shift with time on to a linear model. The Gompertzian model involves a quadratic terms and that limit growth. We looked into Iwata et al paper it discusses a different model and takes into account the growth and metastasis of a tumor population but does not look into tumor shrinking or chemotherapy. Our new model focuses on the extending Iwata et al model to take into account tumor …

Direct Current Stimulation Modulates Ltp And Ltd: Activity-Dependence And Dendritic Effects, Gregory Kronberg

Dissertations and Theses

Transcranial direct current stimulation (tDCS) has been reported to improve various forms of learning in humans. Stimulation is often applied during training, producing lasting enhancements that are specific to the learned task. These learning effects are thought be mediated by altered synaptic plasticity. However, the effects of DCS during the induction of endogenous synaptic plasticity remain largely unexplored. To model endogenous plasticity I induced long-term potentiation (LTP) and depression (LTD) at Schaffer collateral synapses in CA1 of rat hippocampal slices. When induction was paired with concurrent DCS, the resulting plasticity was biased towards potentiation, such that LTP was enhanced and …

Alongside its current widespread clinical applications for diagnosis and treatment, MRI allows researchers to measure structure and function of different tissue types in order to advance our understanding of human biology and enable new medical applications of MRI. In particular, diseases affecting nerves and vessels, such as trigeminal neuralgia, with uncertain etiology can be studied using multiple MRI modalities so that treatment planning can we more effective and patient outcomes can be improved. Ultrahigh field MRI scanners, such as those …

Innovative System For Seismic Control Strategies, Seyed Ali Razavi

Dissertations and Theses

Among various alternative approaches, installing auxiliary damping devices such as tuned mass dampers (TMDs) is a very reliable solution to mitigate wind-induced vibration of tall buildings. However, regardless of the different distribution strategies, installing TMD systems means adding additional masses to tall buildings. A valuable space on top of tall buildings is sacrificed to contain a large bulky mass, which is not aesthetically pleasing. Furthermore, increasing the mass of tall buildings by installing extra mass systems is not time and cost effective process. In order to address the issues, this paper investigates the utilization of feasible alternative for the purpose …

Vehicle Engine Classification Using Of Laser Vibrometry Feature Extraction, Chi Him Liu

Dissertations and Theses

Used as a non-invasive and remote sensor, the laser Doppler vibrometer (LDV) has been used in many different applications, such as inspection of aircrafts, bridge and structure and remote voice acquisition. However, using LDV as a vehicle surveillance device has not been feasible due to the lack of systematic investigations on its behavioral properties. In this thesis, the LDV data from different vehicles are examined and features are extracted. A tone-pitch indexing (TPI) scheme is developed to classify different vehicles by exploiting the engine’s periodic vibrations that are transferred throughout the vehicle’s body. Using the TPI with a two-layer feed-forward …

Public-Private Partnerships: Instruments To Enhance Education, Training And Employment Opportunities In The Republic Of South Africa, Lynne Scott Jackson

Dissertations and Theses

Since the fall of apartheid in 1994, government, business leaders and nongovernmental organizations (NGOs) are in a unique position to engage civil society and link educational institutions with industry-specific partners committed to stimulating economic development and employment options for citizens. This thesis explores the conditions under which public-private partnerships (PPPs) are likely to successfully generate sustainable youth employment and equip citizens with transferrable skills and the conditions under which they are likely not to generate opportunities. The thesis argues that PPPs are most likely to be successful when there is grassroots buy in from local communities. Based on the literature …

Change And Continuity: Turkish Foreign Policy Since 2002, Under The Justice And Development Party (Adalet Ve Kalkinma Partisi - Akp), Ustun Yuksel

Dissertations and Theses

This thesis analyzes the changes and continuity within Turkish foreign policy since 2002, under the Justice and Development Party (Adalet ve Kalkinma Partisi - AKP). In order to understand modern Turkish politics, it is important to realize Turkey’s aspirations of becoming a full member of the European Union and its subsequent push for strategic alliances with the Middle East and former Turkic republics from the Soviet Union. The evidence shows that Turkey has consistently strived to improve its relationship with the EU in its effort to become a full member state, but the EU’s reluctance to accept Turkey as an …

Improving Medicare & Medicaid Reimbursement Framework For Molecular Diagnostics Tests Using Gene Sequencing: A Case Study In Health Economics, Advait Apte

Dissertations and Theses

Breast cancer is the second leading cause of deaths among women, as about one in eight women in the US will develop invasive breast cancer during their lifetime. After the diagnosis of breast cancer, chemotherapy is the commonly prescribed first line of treatment. In the recent past, research has shown that molecular diagnostic tests have revealed that about 20% of the tumors carry the HER-2 mutation on cell surface, which can be treated with the drug Herceptin, or trastuzumab, improving cancer free survival rates from 71.9% to 84.2% in five years. However, in spite of the observed increase in survival …

Desecularization Of The State As A Resistance To The Globalization: A Case Study Of The Criminalization Of Blasphemy In Russia., Artem Profis

Dissertations and Theses

A cultural aspect of westernization remains in the shadow of widely discussed economic and political ones. While many states are conforming to the Western rules of the global market game, the cultural characteristics and differences are less mutable and thus less easily compromised and resolved than political and economic ones. The dissolution of the U.S.S.R. has left behind a void in the Russian identity. After unsuccessful attempts to assume a Western liberal identity during the first half of the 90s, Russia has opted for tried and tested Orthodox Christianity to fill that void and to form a new post-Soviet Russian …

Determining The Predictive Ability Of Rural-Urban Migration For Health Indicators In China, Christopher Rick

Dissertations and Theses

Over one hundred million rural Chinese residents have migrated to urban areas within China for work. In cities, these workers often lack access to health insurance and licensed healthcare. Migrants are also more likely to work in dangerous jobs and to participate in high-risk behaviors. This paper analyzes two health indicators, blood pressure and grip strength, to determine if migrant status can predict health. This paper determines that migrant status is a significant predictor for blood pressure and grip strength, albeit in models with low predictive ability. However, the length of time since a person migrated is not a significant …

Evidence For The Drainage Of A Superglacial Lake As The Source Of Seismic Waves Recorded At A Regional Distance, Erik J. Orantes

Dissertations and Theses

Surface melting during the summer leads to the formation of lakes on the Greenland Ice Sheet surface, known as supraglacial lakes. Some of these lakes drain through cracks in their beds and release the water into the ice sheet. Previous studies suggest that some of the water reaches the bedrock, enabling basal sliding, which could potentially increase glacial discharge (Sundal et al., 2009). Das et al. (2008) showed that supraglacial lake drainage can be accompanied by seismic activity, but little work has been done on the regional detection of such waves. The present study analyzes seismic data for the period …

Chapter 11 Shapeshifters, Lindsey Simon

Scholarly Works

Logic and equity would seem to demand that when administrative agencies are creditors to a bankrupt debtor, they should have the same status as other creditors. But a creditor agency retains its regulatory authority over the debtor, permitting it to continue with agency business such as conducting enforcement proceedings and awarding licenses. As a result, though bankruptcy law and policy both strongly support equal distribution of the estate, administrative agencies have been able to circumvent these goals through the use of “shapeshifting” behaviors. This Article evaluates two dangerous shapeshifting scenarios:

(1) where the agency avoids the limitations of creditor status …

Nurses' Perceptions Of Diagnosis And Prognosis-Related Communication: An Integrative Review, Amy Rose Newman

College of Nursing Faculty Research and Publications

Background: Disclosure of diagnostic and prognostic information has become the standard in the United States and increasingly around the world. Disclosure is generally identified as the responsibility of the physician. However, nurses are active participants in the process both intentionally and inadvertently. If not included in initial discussions regarding diagnosis and prognosis, the nurse may find it challenging to openly support the patient and family.

Objective: The aim of this study is to synthesize published literature regarding nurses’ perceptions and experiences with diagnosis and prognosis-related communication.

Methods: The Whittemore and Knafl method guided the integrative review process. …
