description: In the current study, the wear behavior of bronze-bonded grinding tools when grinding the titanium alloy Ti-6Al-4V was explored. In this process, oxidation plays a key role since both the bronze bond and the titanium workpiece chemically react with oxygen. The oxidation effect is intensified further due to increased temperatures during grinding and can cause tribo-oxidation. This wear effect can be reduced or even eliminated by grinding in an extreme high-vacuum (XHV) adequate atmosphere. This atmosphere is nearly oxygen-free and is generated using a silane-doped argon gas that chemically reacts with oxygen. This reaction is able to decrease the oxygen partial pressure (pO2 ≤ 10−12 mbar) down to an XHV-adequate atmosphere. The aim of this paper is to investigate the influence of oxygen in the atmosphere on the application and wear behavior during grinding and to demonstrate the potential of this novel approach. The results presented show that during grinding with cBN, the process forces are significantly influenced by the atmosphere. Depending on the process parameters, a reduction of up to 93% is thus possible. This force reduction correlates with radial tool wear. When grinding under oxygen-free conditions, it can be reduced by up to 64%.

description: In this paper, questions of determination of the sizes of electrodes of capacity measuring transducers depending on tolerated relative error of measurement are considered. Dependences of ways of laying of grain materials on their electrical conductance are analyzed. It is established that the problem of optimization can be solved by the determined and statistical methods. At the determined method, it is accepted that all particles of the contacting layer with an electrode of bulk materials are located in order. At the statistical technique, the arrangement of particles is accidental,submitting to any distribution law, for example, normal. The example of calculation of the sizes of electrodes, near-optimal determined, and static ways are shown.

description: This study examined for the first time the microbial community and biogeochemical cycling of methane and oxygen in Base Mine Lake, the reclamation site of a former tailings pond in the Athabasca oil sands region of Northern Alberta. Base Mine Lake represents the first large-scale demonstration of the “water-capped end pit lake” approach to tailings pond reclamation, with the ultimate goal of transitioning the lake into a natural, self-sustaining ecosystem. The oxygenated upper portion of the lake is home to aerobic hydrocarbon degrading bacteria, including a diverse population of methane oxidizing bacteria, whose activity, dispersion, and community composition is greatly influenced by seasonal variation. The majority of methanotrophs in the lake belong to the class Gammaproteobacteria, although Alphaproteobacteria methanotrophs make up a relatively large percentage of methanotrophs during summer stratification. Methanotroph abundance and potential for methane oxidation are relatively high during periods of turnover or partial mixing in the lake, and decrease during stratification.
When atomic-scale resolution is not enough: Spatial effects in in situ model catalyst studies

description: We investigate transport effects in in situ studies of defined model catalysts using a multi-scale modeling approach integrating first-principles kinetic Monte Carlo simulations into a fluid dynamical treatment. We specifically address two isothermal flow setups: i) a channel flow with the gas-stream approaching the single crystal from the side, as is representative for reactor scanning tunneling microscopy experiments; and ii) a stagnation flow with perpendicular impingement. Using the CO oxidation at RuO2 (110) as showcase we obtain substantial variations in the gas-phase pressures between the inlet and the catalyst surface. In the channel geometry the mass transfer limitations lead furthermore to pronounced lateral changes in surface composition across the catalyst surface. This prevents the aspired direct relation between activity and catalyst structure. For the stagnation flow the lateral variations are restricted to the edges of the catalyst. This allows to access the desired structure-activity relation using a simple model.

description: The destabilizing power of a traumatic experience has been widely discussed in many studies; however, on the other hand, many studies in psychological literature show a different view of this experience. This study addresses the positive meaning and the transforming power of an event, which, although devastating, reveals to the subject skills, unknown until now. Referring to recent longitudinal studies (Cimino, S., Sinesi, S., Monniello, G., (2012); Cimino, S., Monniello, G., Cerniglia, L., Ballarotto G. (2013) it is proposed to highlight how it is an usual position which is generated in order to deal with the pain. In these studies, the traumatic event taken into account concerns parental loss in children and adolescents (development age) in the attempt to explore, by the use of specific instruments such as Symptom Checklist – 90 – R, (Derogatis, 1994); Eating Attitude Test-40 (Garner and Garfinkel, 1979) and Adolescent Dissociative Experiences Scale (Armstrong et al., 1997), the multiple aspects of the subjective answer to the traumatic event. In addition, a more systemic review is given to the different measures of resilience, such as: dispositional measures (Miller Behavioral Style Scale, Miller, 1987) and situational ones (Ways of Coping Questionnaire, Lazarus and Folkman, 1984); and also, to the psychotherapeutic processes intended as an element to promote the increment of such capacity with a particular reference to the cognitive-behavioral and systemic-relational model.                                                                           Finally, special attention is given to the protective value of a secure attachment, together with the ability for mentalization, considered as aspects capable of strengthening some important cognitive-emotional self regulation abilities and, therefore, promoting the development of resilient behavior. In conclusion, the many aims of this study are: to provide a right definition of resilience, to try analysing and fixing solutions about the main theoretical controversies over this matter; moreover, this study tries to highlight all those factors that contribute to influence resilient behaviours and to identify strategies and procedures that can facilitate or hinder their execution.

description: Vitamin D deficiency (<50nmol/L 25-hydroxy vitamin D) affects more than 1 billion people worldwide. Furthermore, cardiovascular disease (CVD) is a common cause of mortality globally. Observational studies have shown that vitamin D deficiency and CVD are associated, specifically in the chronic kidney disease (CKD) population whom are burdened with both increased risk of CVD-related death and vitamin D deficiency, though whether this relationship is causal in nature is not clear. Electrocardiogram recordings are used to quantify sympathetic and parasympathetic (vagal) control over the heart (cardiac autonomic tone, CAT), which has been shown to predict CVD-related outcomes. A series of studies was conducted across a range of populations with varying kidney function to assess the impact of vitamin D deficiency and supplementation on CAT. In healthy humans undergoing an angiotensin II (AngII) vascular stress test prior to vitamin D supplementation, subjects with low 1,25(OH)2 vitamin D experienced withdrawal of cardioprotective vagal tone and an upwards shift in overall cardiosympathovagal activity [(∆HF from baseline = -6.98±3, p=0.05; ∆LF:HF from baseline = 0.34±0.1, p=0.043 vs. above 25th percentile]. Following 4 weeks of oral vitamin D3 supplementation, vagal activity during the same AngII stressor was restored (∆HF from baseline 9.5±5 vs. -2.8±3, p=0.07 vs. pre-supplementation). The same study with vitamin D deficient IgA nephropathy (IgAN) subjects yielded similar results. The VITAH Trial then aimed to assess whether a causal relationship existed between activated vitamin D supplementation and CAT in end-stage kidney disease (ESKD) patients requiring hemodialysis. In contrast to healthy and IgAN subjects, six weeks of oral 1,25(OH)2 D supplementation (0.25mcg alfacalcidol 3x per week) or combined activated and nutritional supplementation (additional 50,000IU ergocalciferol 1x per week) enhanced cardiosympathovagal balance during hemodialysis in vitamin D deficient subjects (activated: n=13, ∆LF:HF: 0.20 ± 0.06, p<0.001 vs. ∆LF:HF in non-deficient; combined: n=8, deficient: ∆LF:HF: 0.15 ± 0.06, p<0.001 vs. ∆LF:HF in non-deficient). These novel findings indicate that vitamin D deficiency impairs the regulatory capabilities of the autonomic nervous system during vascular stress, and that vitamin D supplementation may mitigate the risk of CVD-related mortality in humans specifically in the setting of advanced CKD.

description: We report the results of a search for an emission line from radiatively decaying dark matter in the ultra-faint dwarf spheroidal galaxy Willman 1 based on analysis of spectra extracted from XMM-Newton X-ray Observatory data. The observation follows up our analysis of Chandra data of Willman 1 that resulted in line flux upper limits over the Chandra bandpass and evidence of a 2.5 keV feature at a significance below the 99% confidence threshold used to define the limits. The higher effective area of the XMM-Newton detectors, combined with application of recently developing methods for extended-source analysis, allow us to derive improved constraints on the combination of mass and mixing angle of the sterile neutrino dark matter candidate. We do not confirm the Chandra evidence for a 2.5 keV emission line.

description: We propose a method for automatic local time-adaptation of the spectrogram of audio signals: it is based on the decomposition of a signal within a Gabor multi-frame through the STFT operator. The sparsity of the analysis in every individual frame of the multi-frame is evaluated through the Rényi entropy measures: the best local resolution is determined minimizing the entropy values. The overall spectrogram of the signal we obtain thus provides local optimal resolution adaptively evolving over time. We give examples of the performance of our algorithm with an instrumental sound and a synthetic one, showing the improvement in spectrogram displaying obtained with an automatic adaptation of the resolution. The analysis operator is invertible, thus leading to a perfect reconstruction of the original signal through the analysis coefficients.

description: In 1241, Mongol armies invaded Poland and Hungary, and small reconnaissance forces even penetrated the borders of the Holy Roman Empire. The following year, the Mongols pulled out of Central Europe though they retained their hold on Russia, the Black Sea steppe, and the Volga region. A number of explanations have been offered for the withdrawal by modern scholars. This thesis argues that these theories are unconvincing and contradicted by the existing primary source evidence. As an alternative explanation, it posits that European fortifications produced a strategic problem that the Mongols were unable to surmount in the 1240s with their available manpower and siege engine technology. In order to corroborate this theory, analyses of several Mongol campaigns against sedentary societies outside of Europe are provided. These analyses reveal that fortifications posed a serious problem to any Mongol effort to subjugate a sedentary population.

description: We investigate dynamical many-body systems capable of universal computation, which leads to their properties being unpredictable unless the dynamics is simulated from the beginning to the end. Unpredictable behavior can be quantitatively assessed in terms of a data compression of the states occurring during the time evolution, which is closely related to their Kolmogorov complexity. We analyze a master equation embedding of classical cellular automata and demonstrate the existence of a phase transition between predictable and unpredictable behavior as a function of the random error introduced by the probabilistic character of the embedding. We then turn to have this dynamics competing with a second process inducing quantum fluctuations and dissipatively driving the system to a highly entangled steady state. Strikingly, for intermediate strength of the quantum fluctuations, we find that both unpredictability and quantum entanglement can coexist even in the long time limit. Finally, we show that the required many-body interactions for the cellular automaton embedding can be efficiently realized within a variational quantum simulator platform based on ultracold Rydberg atoms with high fidelity.

However, despite the strengths of the article, we have certain reservations on the methodology followed and conclusions drawn in the study that need to be elaborated for a better understanding of this very important research. Our correspondence thus, emphasizes the need for further explorations on this important area of research on mental health in inmates, in order to identify appropriate diagnostic and therapeutic strategies to be applied in this population.

Using experimentally determined parameters and uncorrelated site energy fluctuations, the model predicts oscillations in the nonlinear spectra of the Fenna-Matthews-Olson (FMO) complex with a dephasing time of 1.3 ps at 77 K. These oscillations correspond to the coherent superposition of vibronic exciton states with dominant contributions from vibrational excitations on the same pigment. Purely electronic coherences are found to decay on a 200 fs timescale.

description: Psychopathology is a field not much explored by the systemic-relational theory and, in particular, scientific works on Personality Disorders are lacking. The aim of this work is to understand whether and how many scientific works have treated the narcissistic personality through the theoretical premises of systemic-relational approach.

We carried out a systematic review of the scientific literature to identify and discuss existing studies, with the intent to define a starting point for the analysis of the system that onsets and maintains the narcissistic personality.

Few articles were selected. Despite they describe differently the narcissistic personality and the system within which the symptomatology develops, there are some similarities. They concern the diffusion of family boundaries and the rejection of individual characteristics within the system, the childhood parentification and the need to maintain the external appearance.

description: The article substantiates the need to develop generalized indicators to assess the effectiveness of complex systems as «smart» networks. For a comprehensive and objective assessment of the microgrid operation efficiency, studies conducted world-wide aimed at creation of a single efficiency indicator by generalizing indicators of energy efficiency are analyzed. The priority area of research is development of a generalized indicator of the relative normalization of performance indicators and determination of a rational order of ranking these indicators in order of importance. For selection and ranking of indicators, we use the method of “expert assessments”. When choosing indicators, the «minimum of reduced costs» criterion is used. The effect of studied indicators on the total costs of the microgrid is determined. Generalized efficiency indicator of the «smart» grid consists of capital investment efficiency factor, energy source efficiency factor, off-line operation factor (automation) of grid; power quality factor; energy factor of microgrid. Generalized indicator of microgrid efficiency is obtained by means of relative normalization of efficiency indicators and their generalization to a single factor. Order of ranking of generalized indicators and weight is selected with taking into account their influence on the generalized efficiency indicator. Algorithm and software code are developed for calculation of generalized efficiency indicator that allows energy monitoring of power consumption in «on-line» mode.

description: The use of sophisticated machine learning (ML) models, such as graph neural networks (GNNs), to predict complex molecular properties or all kinds of spectra has grown rapidly. However, ensuring the interpretability of these models’ predictions remains a challenge. For example, a rigorous understanding of the predicted X-ray absorption spectrum (XAS) generated by such ML models requires an in-depth investigation of the respective black-box ML model used. Here, this is done for different GNNs based on a comprehensive, custom-generated XAS data set for small organic molecules. We show that a thorough analysis of the different ML models with respect to the local and global environments considered in each ML model is essential for the selection of an appropriate ML model that allows a robust XAS prediction. Moreover, we employ feature attribution to determine the respective contributions of various atoms in the molecules to the peaks observed in the XAS spectrum. By comparing this peak assignment to the core and virtual orbitals from the quantum chemical calculations underlying our data set, we demonstrate that it is possible to relate the atomic contributions via these orbitals to the XAS spectrum.

description: The aim of the present study is to investigate the role of emotional variables in diabetes adaptation. This is in order to develop and test a conceptual model simultaneously involving emotional variables consistent with a conceptual framework looking at chronic illness as a loss of good self. A convenience sample of 59 participants with a diagnosis of type 1 (n= 26) and type 2 (n=33) diabetes mellitus (Mean age= 57.17, SD=16.82) completed measures of diabetes distress, psychological adjustment to diabetes, diabetes self-care (as outcomes of diabetes adaptation) and depression, alexithymia and damaged ego-related strategies (as emotional variables). Correlation analyses among the examined measures were performed; as well, regression analyses were used to test the role of such emotional variables (as potential predictors) in accounting for diabetes adaptation outcomes. The results overall suggest that lower depression and higher mania contribute to diabetes adaption to a statistically significant extent, despite mania not being associated with self-care behaviors. The study raises a controversial debate about the meaningfulness of the psychological process of adjustment to diabetes without considering the role of underlying symbolic and less conscious dynamics.

description: Adequate sedation of patients for endoscopic procedures has been associated with increased tolerance and acceptability of the procedures. The study aim is to determine if the timing of sedation in relation to the procedure start time is related to patient comfort scores for adult patients undergoing a screening colonoscopy at the Colon Cancer Screening Center (CCSC). A review of 176 randomly selected charts from completed procedures was conducted at the CCSC. Nine data points and comfort scores that are routinely collected during admission and colonoscopy procedures were compiled and analyzed to discover any existing relationships. No significant relationship was discovered between the timing of the sedation, procedure length and patient comfort during colonoscopy procedures at the CCSC. Although no significant relationship was discovered, important baseline data was the result of this study. Further study is needed to understand the factors associated with patient discomfort during colonoscopy procedures.

description: Automatic code generation is a standard method in software engineering since it improves the code consistency and reduces the overall development time. In this context, this paper presents a design flow for automatic VHDL code generation of mppSoC (massively parallel processing System-on-Chip) configuration. Indeed, depending on the application requirements, a framework of Netbeans Platform Software Tool named MppSoCGEN was developed in order to accelerate the design process of complex mppSoC. Starting from an architecture parameters design, VHDL code will be automatically generated using parsing method. Configuration rules are proposed to have a correct and valid VHDL syntax configuration. Finally, an automatic generation of Processor Elements and network topologies models of mppSoC architecture will be done for Stratix II device family. Our framework improves its flexibility on Netbeans 5.5 version and centrino duo Core 2GHz with 22 Kbytes and 3 seconds average runtime. Experimental results for reduction algorithm validate our MppSoCGEN design flow and demonstrate the efficiency of generated architectures.

description: This paper traces the concept of censorship in the light of the most recent conceptualizations both in the psychoanalytic and in the neurosciences. In particular, we focus on the thought of Bion, Matte Blaco, Civitarese, Bucci, Panksepp and Solms. The scientific contributions are then used for a comparison and for a reading of the forms of censorship in the current society. In particular, the importance of the emotional dimension is emphasized, rather than the cognitive one, as a tool to face the censorship.

description: A symmetric and conserved energy-momentum tensor for a scalar field in a moving medium is derived using the Gordon metric. When applied to an electromagnetic field, the method gives a similar result. This approach thus points a way out of the old Abraham-Minkowski controversy about the correct energy-momentum tensors for the electromagnetic field in a material medium. The new tensor describes the properties of the field while the Abraham tensor contains information about the field coupled to the medium.

Methods: A sample of 268 medical students participated in this study. Internet addiction was assessed using Malay version of Chen Internet addiction Scale while the prevalence and severity of depression, anxiety and stress were assessed by Depression Anxiety, Stress Scale (DASS-21).

Results: The rate of IA among students was 22.8%. No significant differences in terms of gender and other socio-demographic factors. IA was significantly associated and positively correlated with depression and anxiety symptoms but has inverse correlation with social interaction. Multiple linear regression analysis showed that stress (β = 0.261, P = 0.005) was a significantly important risk factor.

Conclusions: IA is potentially high among medical students. Male and female students are equally affected. IA is significantly higher among students with poor social interaction. IA has a positive correlation with depression, anxiety and stress symptoms but inverse correlation with social interaction and stress can be considered as a predictive factor for IA.

description: In a series of two recent papers, the frequency and size distribution dependence of extinction spectra for astronomical silicate and graphite grains was analyzed by us in the context of MRN type interstellar dust models. These grains were taken to be homogeneous spheres following the power law $(a^{-3.5})$ size distribution which is very much in use. The analytic formulas were obtained for the graphite and silicate grains in wavelength range 1000Å- 22,500Åand their utility was demonstrated. In this paper of the series, we present analytic formulas for the scattering and absorption spectrum of another important constituent of interstellar dust models, namely, the polycyclic aromatic hydrocarbons (PAHs). Relative contribution of the PAHs to extinction {\it vis a vis} carbonaceous classical grains has been examined.

description: Adaptive pole placement algorithms for non-minimal phase stochastic systems are presented. The characterization of the structure and the set of models of linear dynamic control objects are carried out. As an example, the algorithm of the extended self-tuning controller is considered. To find the estimate of the controller parameters, the recursive least squares method is used. An explicit algorithm is proposed that makes it possible to exclude the operation of matrix inversion, which requires significant computational costs. Pole placement algorithms are given in the presence of white noise at the output. These algorithms belong to the class of stochastic approximation algorithms, the convergence of which is much lower than that of recurrent least squares algorithms. The results of numerical analysis have confirmed their efficiency, which makes it possible to use them in solving applied problems of identification and synthesis of adaptive control systems for technological objects.

description: The aim of the research is to measure the relations and the directions of two modalities to study the approach to objects and learning. An observation group of 213 subjects, 93 males (43,7%) and 120 females (56,3%), (average of 24,73 years old; SD 2,28) all students from the V year Medicine and Surgery from the University of Messina, were involved. The evaluation was carried out with The Kolb's LSI II (Italian Adaptation) and the Mayers-Bryggs Type Indicator. Descriptive and correlational analysis were carried out.


Significant correlations emerged respectful to the Jung's introversion and extraversion (Hp 1), so that we assist to a positive correlation among every style. Referring to Learning Styles and the Jung's functions (Hp 2), significant positive and negative correlations emerged, but for AE. Significant and negative correlations emerged for judging functions, AC and RO (Hp 3). Negative correlations were highlighted by the relation among the two Leaning Styles groups and judging functions (Hp 4).


The study could provide an integrative way to consider the teaching activity and  the curricula . The relations suggest that the awareness of the students about their learning and adaptation process can provide a viable mode to satisfy their desires.

Greek and Near Eastern warfare 3000 to 301: the development and perfection of combined arms
Creators: name: Wrightson, Graham Charles Liquorish
Publisher: name: Graduate Studies
Year: 2012
Subjects: subject: Ancient
subject: Military

description: This dissertation traces the developments in battlefield tactics from the early Mesopotamian societies through to the battle of Ipsus in 301 BCE. The primary concern is an analysis of the system of combined arms and its gradual implementation in the Near East and Greece. This thesis will show that armies using combined arms generally proved to be more successful than those that did not. Moreover the use of combined arms was one of the underlying causes for the many victories of the most successful conquest societies in this period, principally Neo-Assyria and Macedon. Conversely the Persian Empire was created through the use of overwhelming resources but was defeated precisely because of its minimal use of combined arms. Overall this thesis will provide a thorough examination of the history of combined arms in ancient warfare and a detailed analysis of its benefits.

description: We analyze the steady-state entanglement between Bose-Einstein condensate trapped inside an optical cavity with a moving end mirror (nanomechanical resonator) driven by a single mode laser. The quantized laser field mediates the interaction between the Bose-Einstein condensate and nanomechanical resonator. In particular, we study the influence of temperature on the entanglement of the coupled system, and note that the steady-state entanglement is fragile with respect to temperature.

description: In this dissertation, I investigated children’s development of topographical orientation skills. Specifically, I examined children’s performance on a navigation task in a virtual museum. In Chapter 2, I described the methodology used in this experiment. The computer task comprised of an interactive game that consisted of three sections: a practice motor task, a guided tour around a virtual museum, and a testing phase. After children were introduced to the environment, they were required to navigate from one location of the museum to a goal location as quickly as possible. Game performance was assessed by how much time and travel distance were required to reach a target location. In order to assess different cognitive domains supporting topographical orientation skills, a neuropsychological battery was administered. Finally, both children and parents completed self-rated questionnaires of the children’s general spatial behaviours. In Chapter 3, the main experimental results were described. Game performance was significantly correlated with age and several neuropsychological measures with emphasis on visual spatial processing. Game performance was also correlated with history of gaming experience and technology use. A multiple linear regression analysis revealed that game performance was best explained by performance on spatial working memory and visual-spatial organization tasks, once video game experience was accounted for. Only children’s self-reported ratings of their spatial orientation and navigation skills were correlated with one of two measures of game performance, whereas parents’ ratings were not. When compared to adult performance on the computer game, even the oldest group of children tested was still not as efficient as adults in solving the task, suggesting that development of topographical orientation skills continue well into adolescence and young adulthood. Chapter 4 summarized and explored the aforementioned findings in greater detail. Additional statistical analyses and discussion regarding the pilot study, a group of children who participated in a repeat session of the computer game, and a group of younger children tested are described in Appendix B.
Towards the reduction of occupational exposure to cytotoxic drugs

description: Background: One of the most powerful and widely used techniques in cancer treatment is the use of cytotoxic drugs in chemotherapy. These drugs are inherently hazardous with many of them causing carcinogenic, mutagenic or teratogenic health outcomes. Occupational exposure to cytotoxic drugs is of great concern due to their lack of selectivity between healthy and unhealthy cells. Widespread cytotoxic drug contamination has been reported in North America, Europe and Australia. Current cleaning protocols for hazardous antineoplastic drugs include the use of disinfectants and oxidizing agents, such as household bleach. Aim: The thesis project focused on two objectives: 1) hypothesize and confirm potential hazardous byproducts arising from cleaning cyclophosphamide, a widely used cytotoxic drugs, with household bleach, a commonly used cleaning agent; 2) develop an effective and safe cleaning agent for cytotoxic drugs in order to prevent and eliminate exposure to these drugs. Methods: The gas chromatograph mass spectrum (GC/MS) was used to analyze the decomposition of cyclophosphamide by household bleach (5.25% hypochlorite). The reaction was conducted in a test-tube and the by-products extracted and derivatized prior to analysis. Multiple cleaning agent compositions were tested on 10x10cm stainless steel plates spiked with the two model cytotoxic drugs, cyclophosphamide and methotrexate. A wipe-sampling procedure was used to determine amount of contamination present on surface post cleaning with different cleaning agent compositions. Analysis of wipes was conducted on a liquid chromatography tandem mass spectrum (LC/MS/MS). Results: Decomposition of cyclophosphamide by household bleach was determined to produce nornitrogen mustard. Production of nor-nitrogen mustard was determined to be dependant to reaction time and volume of household bleach used. A safe and effective cleaning agent for cytotoxic drugs, which acts by dissolving the contamination and not by decomposition, was developed. The cleaning agent was determine to remove >98% (methotrexate) and >95% (cyclophosphamide) of contamination by using a one-wipe procedure. A systematic cleaning protocol is recommended by using a two-wipe procedure followed by the use of isopropanol. Conclusion: Decomposition of cytotoxic drugs on surface can lead to unwanted and hazardous exposure. Cytotoxic drug contamination can be safely removed from surfaces without decomposition.

description: Pursuant to the Paris Agreement, many countries intend to fulfill their carbon mitigation obligations by operating cap-and-trade schemes. While desirable, linking various cap-and-trade schemes to form a global carbon market is complex because it involves the collaboration of disparate schemes that governments have developed independently of each other. Because governments will design such schemes according to their own domestic priorities, heterogeneous carbon credits created from these schemes will have varying levels of environmental integrity. This thesis examines whether carbon credits should be traded like commodities or like currencies to achieve environmental integrity in linked cap-and-trade schemes. This thesis recommends that heterogeneous carbon credits should be traded like currencies by using carbon exchange rates that calibrate their varying carbon mitigation values to make them truly fungible. A carbon currency trading model will ensure the environmental integrity of linked cap-and-trade schemes to collectively mitigate climate change on an international scale.
