Polymorph Screening and Characterization of Active Pharmaceutical Materials

Polymorphs are solid compounds that can take on various forms. Since polymorphs of the same type of material normally exhibit different physical properties, it is very important that polymorphs be known so that useful forms of materials can be consistently controlled in the production process. This project will look at improving pharmaceuticals by finding more polymorphs of materials by polymorph screening, manipulating the external conditions that the materials are subjected to in order to have them undergo polymorphism. This study intends to find new crystal forms that could further be used to improve pharmaceuticals as well as to learn how to prepare polymorphs and operate various characterization apparatus.

Glycoprofiling of Erythropoietin using High Resolution Capillary Electrophoresis-Mass Spectrometry

Erythropoietin is a protein with attached sugars that stimulates the production of red blood cells. As such, it can be used by athletes to enhance their competitive performance, an act that is called doping. Erythropoietin that us used for doping is typically produced in animal cells, which functionalize the protein with sugars that differ from those produced in human cells. Jessica Risley’s project is to develop a method of analysis using capillary electrophoresis coupled to high resolution mass spectrometry to detect this difference in sugars quantitatively and use the information to later test samples to determine whether or not doping has occurred.

Ammonia nitrogen removal from melamine wastewater by biological fluidized bed

The purpose of the research project to be performed at the Zhejiang University of Technology is the study of the hydraulic characteristics associated with removal of ammonia nitrogen and chemical oxygen demand (COD) from wastewater treated in an anaerobic-aerobic fluidized bed. Most of the current biological denitrification processes are performed by some form of biological method but are only suitable for removal of relatively low ammonia nitrogen concentrations due to the requirement of an appropriate carbon to nitrogen ratio. Thus, there is a need to study the hydraulic characteristics of the proposed process in order to determine optimal reactor conditions for ammonia nitrogen removal. The main expected outcome of the research project is the achievement of maximum removal efficiency of both COD and ammonia nitrogen from melamine wastewater, which is made possible by a high resistance to organic loading in the reactor.

Nitrous oxide emissions from fertilized cotton (Gossypium hirsutum L.) under a drip drip irrigation as influenced by nitrogen fertilizer placement depth and rate.

Irrigated cotton (Gossypium hirsutum) in arid areas of China receive very high nitrogen inputs of up to 240 kg/ha-1. The crop also receives large inputs of irrigation water mostly under drip irrigation system. This system will be used to determine the contribution of processes of nitrification and denitrification (microbial processes involved in the production of nitrous oxide) to total nitrous oxide fluxes from the soil. Urea will be applied at different depths and rates. Each microbial process will be linked to these aforementioned variables. The study will be established at the beginning of the cotton cycle with labeled nitrogen (15N) applied to distinguish the contribution of nitrification and denitrification to nitrous oxide fluxes. We expect deeper placement of nitrogen to have a mitigatory effect on nitrous oxide emissions especially when the application rates are high. TO BE CONT’D

Fresh State Characterization of Low-Cement Content Concrete

In 2010 and 2015, the cement industry produced approximately 3.3 and 4.1 billion tons of cement, respectively; hence almost 2 and 2.5 billion tons of carbon dioxide (CO2) were emitted, respectively. Given this rapid growth of CO2 emissions together with the importance of cement in concrete strength development, research studies have focused on approaches to reduce the CO2 of cement consumption. Although it is necessary to reduce cement use to produce a more environmental friendly concrete, it is important to analyze its effects on concrete durability. Reducing the cement content will lower concrete pH, which is normally very alkaline. This could affect concrete durability because high pH values protect against corrosion of the reinforcing steel. This research will characterize the low-cement content concrete on fresh state to conclude how the reduction of cement affects concrete porosity and viscosity, that will change concrete durability.

Shear Behaviour of Concrete affected by Alkali-Aggregate Reaction

The first part of this thesis project consist in a study of the structural behavior, mainly focusing on shear resistance, of concrete elements affected by alkali-aggregate reaction (AAR), an internal swelling reaction. Especially in the presence of moisture, this reaction causes the concrete to expand and form internal cracks. This expansion and formation of cracks is generally associated with a decrease in the mechanical properties of the concrete material. Shear issues of affected concrete is one critical thing to investigate, as they can lead to brittle failures. The chemical and physical processes associated with AAR have now been the subject of considerable research, but there’s a current lack of knowledge with the actual implications on shear performance of affected concrete structures.

Application of the Potts model to find the structure-function relationship of the Brain

Complexity of human brain is limiting our understanding about the mechanisms that dominate its spontaneous activity. An understanding about the architecture of the axonal fibers in the brain and how they support the functions is crucial when it comes to dealing with brain injuries. A mathematical model, was investigated to gain an understanding about the relationship between the structure and the function of the brain. The proposed project aims to extend this understanding by developing a more generalized model to explain the role of the anatomical structure of the brain which is believed to influence brains’ spontaneous activity. Gaining the necessary knowledge about the model as well as the computer simulations are expected by the end of this project as well as a more generalized model which could predict the spontaneous activity of the brain using the distribution of the axonal fiber bundles.

Examining favelas, media, and activism in the 2016 Rio de Janeiro Olympics

In the days leading up to the 2016 Rio de Janeiro Olympic Games, Brazilian favelas were heavily sensationalized in international mainstream media as state surveillance, increased policing, and the criminalization of poverty practices were increasingly enforced in favelas for the preparation of the Olympic Games. Yet, from within favelas was the emergence of a very different discourse. Through ‘favela media activism’, which represent the actions of residents to create awareness about social inequalities, problematize prejudice, and resist discrimination, favela residents have stood collectively to protest gentrification of favelas for the implementation of Olympic development projects as well as to challenge common stereotypes of favelas projects as well as to challenge common stereotypes of favelas (Custódio, 2016). These narratives are of particular significance because they provide insight into the ways in which favelas and the politics of favelas are largely contentious. TO BE CONT’D

Moving towards a more socially sustainable dairy system: Public attitudes to dairy system in Brazil

Animal welfare is a field of animal science that focuses on evaluating and bettering animal lives by investigating biological functioning, affective states, and ability to live naturally. Animal welfare is a measure that is emerging as a key social concern in animal agriculture and as a result, is becoming more prevalent in industry practices. Nonetheless, there is a significant disconnect between public expectations of animal welfare in dairy farming and actual practices that are occurring. If consumers continue to hold animal welfare in high esteem in dairy production and if the Brazilian dairy industry doesn’t change their practices to meet consumer expectations, the dairy industry may be regarded negatively by the public. To avoid such reaction, the Brazilian dairy industry should engage in discussion with the public to initiate a clear path towards establishing methods of care that correspond with public desires.

Toxicity of nanomaterials to Amazonian fish in different water types

The Negro and Solimoes rivers in the Amazon Basin house an incredible diversity of fish, up to 3000 species, and are critical to the economies and cultures of the communities through which they run. The waters of the Rio Negro are clear and black, with a high concentration of dissolved organic material but almost no dissolved salts. The waters of the Solimoes are quite turbid, with a high sediment load and dissolved salt levels more typical of a freshwater river. The unintentional release of toxins from large-scale mining and petroleum extraction industries is a major threat to the health of the Amazonian ecosystem but little is known about the bioactivity of toxins in the unique water types of the Negro and Solimoes rivers.

Understanding best practices for care transitions for patients from hospital to home

Care transitions, the experience for patients of being discharged from hospital to home, is not always well coordinated for patients and their families. This can result in lower quality of care for patients and unsafe situations. Little is know about these care transitions in Brazil. This project will conduct a search of the literature to understand what are the best approaches to ensure that patients experience the best transition possible when being discharged from the hospital. Results of the study will also be shared with decision-makers, health care providers, students, and instructors. The outcomes of the project will include the following: a final report describing the best practices for transitions from hospital to home; a one-page summary of the results to circulate to various audiences; and a presentation. The student will also be involved in discussions on future research in this area.

Engineering Synthetic D-Proteins as Novel and Transformative Molecular Therapeutics Against Cancer Targets

Proteins can exist in two forms: left-handed (L) or right-handed (D); however, for indeterminate reasons life on this planet only uses the L-form. When studied in more detail, both protein forms possess identical physiochemical and biological properties. Yet, D-proteins show minimal proteolytic degradation and fail to elicit immune responses in animals, due to their unnatural arrangement for recognition in biological systems. Accordingly, the proposed project seeks to develop synthetic D-proteins as biopharmaceutical molecules. We will utilize a method of high-throughput selection, previously established for selection of antibodies, to isolate D-proteins to target cellular receptors involved in cancer. TO BE CONT’D
