Lanthanide Complex-Based Luminescent Probes for Highly Sensitive Time-Gated Luminescence Detection of Hypochlorous Acid (2012)

Two novel lanthanide complex-based luminescent probes, ANMTTA-Eu(3+) and ANMTTA-Tb(3+) {ANMTTA, [4'-(4-amino-3-nitrophenoxy)methylene-2,2':6',2"-terpyridine-6,6"-diyl] bis(methylenenitrilo) tetrakis(acetic acid)}, have been designed and synthesized for the highly sensitive and selective time-gated luminescence detection of hypochlorous acid (HOCl) in aqueous media. The probes are almost nonluminescent due to the photoinduced electron transfer (PET) process from the 4-amino-3-nitrophenyl moiety to the terpyridine-Ln(3+) moiety, which quenches the lanthanide luminescence effectively. Upon reaction with HOCl, the 4-amino-3-nitrophenyl moiety is rapidly cleaved from the probe complexes, which affords strongly luminescent lanthanide complexes HTTA-Eu(3+) and HTTA-Tb(3+) {HTTA, (4'-hydroxymethyl-2,2':6',2"-terpyridine-6,6"-diyl) bis(methylenenitrilo) tetrakis(acetic acid)}, accompanied by the remarkable luminescence enhancements. The dose-dependent luminescence enhancements show good linearity with detection limits of 1.3 nM and 0.64 nM for HOCl with ANMTTA-Eu(3+) and ANMTTA-Tb(3+), respectively. In addition, the luminescence responses of ANMTTA-Eu(3+) and ANMTTA-Tb(3+) to HOCl are pH-independent with excellent selectivity to distinguish HOCl from other reactive oxygen/nitrogen species (ROS/RNS). The ANMTTA-Ln(3+)-loaded HeLa and RAW 264.7 macrophage cells were prepared, and then the exogenous HOCl in HeLa cells and endogenous HOCl in macrophage cells were successfully imaged with time-gated luminescence mode. The results demonstrated the practical applicability of the probes for the cell imaging application.
Becoming a Teacher Educator: Journey of a Primary School Teacher (2019)

Purpose : After graduating from the faculties of education in Turkey, some of the teachers start working gravitate towards graduate education. Within or at the end of the process, these teachers start working as teacher educators at universities by finding positions or at least try to accomplish that. We do not have considerable knowledge of what these individuals experience in the process of transition from being a teacher to being a teacher educator. In this study, an attempt was made to examine the experiences of a primary school teacher  who began doing graduate education while he was teaching at a public school and subsequently became a teacher educator at a university. With these experiences, we aimed to understand the dynamics of similar individuals in Turkey Research Methods: This study was designed as - narrative research. Data were obtained through semi-structured interviews with a research assistant who had transitioned from being a primary teacher to being a teacher educator and continued his doctoral studies. In the analysis of interview data, narrative analysis was used. Findings: The findings showed that it can be argued that the perception of teaching in society, the cultures of national schools, economic and socio-cultural factors are effective in teacher’s transition to university. Public schools, with their existing cultures and regulations, are unable to respond to the graduate education demands of teachers who work within the schools. This situation causes teachers who receive graduate education to move away from national public schools. Implications for research and practice: Move away from national public schools can be prevented by removing obstacles of the teachers’ graduate education. In the process of educating teacher educators, the quality of teacher education can be increased by attaching importance to field experience.
Application of two neural network paradigms to the study of voluntary employee turnover. (1999)

Two neural network paradigms--multilayer perceptron and learning vector quantization--were used to study voluntary employee turnover with a sample of 577 hospital employees. The objectives of the study were twofold. The 1st was to assess whether neural computing techniques offered greater predictive accuracy than did conventional turnover methodologies. The 2nd was to explore whether computer models of turnover based on neural network technologies offered new insights into turnover processes. When compared with logistic regression analysis, both neural network paradigms provided considerably more accurate predictions of turnover behavior, particularly with respect to the correct classification of leavers. In addition, these neural network paradigms captured nonlinear relationships that are relevant for theory development. Results are discussed in terms of their implications for future research.
Medien (2010)

Die Betrachtung der Kommunikation im Alltag von Paaren erfolgt vor dem Hintergrund des gesellschaftlichen Metaprozess der Mediatisierung kommunikativen Handelns (Krotz 2001, 2007). Diese Herangehensweise ermöglicht – basierend auf einer Vorstellung von Kommunikation als symbolisch vermitteltes Handeln – ein integratives Verständnis der vielfältigen und komplexen Entwicklungen im Zusammenhang mit Medien und Kommunikation und beschreibt dabei auch den sozialen, kulturellen und gesellschaftlichen Wandel. Dabei sind Alltag, Beziehungen und Identitäten zentrale Aspekte, die eine umfassende Fundierung der Untersuchung von Paarbeziehungen ermöglichen. Zudem kann Mediatisierung in Relation zu anderen gesellschaftlichen Entwicklungen betrachtet werden.
Motion estimation in DCT domain (2002)

In this paper, a new block matching criterion is proposed for motion estimation in video coding. The new criterion is based on a comparison between the discrete cosine transform (DCT) coefficients of two blocks to be matched. Since the spectrum of DCT statistically concentrates on the neighborhood of the dc component and the number of non-zero coefficients is quite small, only few coefficients need to be considered when matching blocks according to the new criterion. Almost in all the video coding standards, DCT is a necessary step for spatial redundancy reduction. Thus the generated DCT coefficients can be utilized in the new criterion. However, there are still some blocks whose DCT coefficients are not available. Several algorithms of calculating DCT coefficients of these blocks are given. When this new criterion is combined with the logarithm search, promising results are produced.
Facile Fabrication of a Three-Dimensional Cross-Linking TiO<sub>2</sub> Nanowire Network and Its Long-Term Cycling Life for Lithium Storage (2014)

We describe a simple preparation of amorphous TiO2 nanomaterial through a simple dealloying method with high throughput at room temperature. The as-made TiO2 sample has a unique three-dimensional network structure built by cross-linking nanowires with the diameter of ∼5 nm. As an anode material for Li-ion batteries, the TiO2 product exhibits high capacities and a long cycling life at high rates of 500 and 1000 mA g(-1). In addition, it has a good rate capability. The as-made TiO2 nanowire network shows great application potential as an anode material with the advantages of unique performance and easy preparation.

Analysis and minimization of ripple components of input current and voltage of PWM inverters (1996)

Analysis and minimization of the ripple components of the input current and voltage of three-phase voltage-source pulsewidth modulated (PWM) inverters are presented in this paper. The analytical expressions for the rms values of the input current and voltage ripples as a function of the shape of the PWM reference signal are derived. It is found that the reference signal which produces a minimum ripple in the input voltage varies as a function of the load power factor. It is also found that the rms value of the inverter input current ripple does not depend on the shape of the reference signal. In respect of the inverter input current and voltage ripples, the addition of harmonics other than the third into the sinusoidal reference is neither useful nor necessary. Experimental results are included to verify the derived expressions.
Geometric models of porosity reduction by ductile grain compaction and cementation (2013)

Pore-volume reduction of sediments by plastic deformation during compaction and by cementation of grains has been evaluated for different proportions of ductile and hard grains. We represent the compaction behavior of grains with a purely geometric model, which uses the cooperative rearrangement algorithm to produce dense, random packings of partly interpenetrating spheres. We varied the fraction of grains assumed to be ductile and the radius of the rigid core of the ductile grains. The predicted relationship between the fraction of ductile grains in the sediment and the porosity after compaction agrees well with previously published experimental data in the literature. The radius of the rigid core of the ductile grains is an effective way to represent different kinds of ductile material, ranging from brittle (rigid radius 0.9) to extremely ductile (rigid radius 0.7). We simulated quartz cementation in our compacted rock by adding isopachous cement. Cement thickness was reduced on the smaller grains and increased on the larger grains to account for presumed export of pressure-dissolved material from finer grained regions and the import of material into coarser grained regions. These simulations yield descriptions of pore-scale geometry resulting from processes common in sandstones. Modeled pore geometry provides insight into transport properties of such rocks. For example, the models predict, to within a factor of five, the permeability of samples of tight-gas sandstones having little intragranular porosity.
Gadolinium Deposition in Neurology Clinical Practice (2019)

<b>Background:</b> Magnetic resonance imaging (MRI) enhanced with gadolinium-based contrast agents (GBCAs) is an essential tool in the diagnosis and management of many neurologic diseases, including multiple sclerosis, brain tumors, and infections. The clinical utility of GBCAs is evidenced by their widespread use. GBCAs are produced in macrocyclic and linear forms. Since 2014, evidence has suggested that repeated administration of GBCAs can lead to gadolinium deposition in the brain. <b>Methods:</b> We review the literature on gadolinium deposition, including both animal and human studies, as well as the literature on GBCA-associated health outcomes. Additionally, we summarize and discuss the updated medical society recommendations and perspectives on GBCA use in clinical practice. <b>Results:</b> The first publication reporting gadolinium deposition in the human brain was published in 2014. Since that seminal report, multiple studies have demonstrated that exposure to linear GBCAs is associated with gadolinium deposition in the dentate nucleus and globus pallidus as seen on brain MRI. Macrocyclic GBCA exposure has not convincingly been associated with gadolinium deposition evident on brain MRI. <b>Conclusion:</b> Clear evidence demonstrates that GBCAs lead to gadolinium deposition in the brain in a dose-dependent manner; however, only linear GBCAs have been associated with gadolinium deposition visualized on MRI. To date, no evidence links gadolinium deposition with any adverse health outcome. Updated medical society guidelines emphasize the importance of an individualized risk-benefit analysis with each administration of GBCAs.
Metabolomics in atherosclerosis (2014)

It is well established that atherosclerotic cardiovascular disease (ACD) is a leading cause of death in the West. There are several predisposing factors for ACD, which can be divided into two groups: firstly modifiable risk factors, including hypertension, dyslipidaemia, type 2 diabetes mellitus, obesity, smoking and a sedentary lifestyle and secondly the unmodifiable risk factors such as age, gender and heredity. Since single biomarkers are unable to provide sufficient information about the biochemical pathways responsible for the disease, there is a need for a holistic approach technology, e.g. metabolomics, that provide sufficiently detailed information about the metabolic status and assay results will be able to guide food, drug and lifestyle optimisation. Rather than investigating a single pathway, metabolomics deal with the integrated identification of biological and pathological molecular pathways. Mass spectrometry (MS) and nuclear magnetic resonance (NMR) spectroscopy are the two most commonly used techniques for metabolite profiling. This detailed review concluded that metabolomics investigations seem to have great potential in identifying small groups of disturbed metabolites which if put together should draw various metabolic routs that lead to the common track pathophysiology. The current evidence in using metabolomics in atherosclerotic cardiovascular disease is also limited and morewell designed studies remain to be established, which might significantly improve the comprehension of atherosclerosis pathophysiology and consequently management.
Rhabdomyolysis (2008)

Rhabdomyolysis is a condition that results from many underlying etiologies and can present in a myriad of ways to the emergency physician. However, some clinical and laboratory features are almost always present and, if noted, can help in making the diagnosis. This review article will focus on the presenting symptoms, the various etiologies, the underlying mechanisms, and the current management of pediatric rhabdomyolysis.

Congener specific polychlorinated biphenyl metabolism by human intestinal microbe <i>Clostridium</i> species: Comparison with human liver cell line-HepG2. (2006)

Polychlorobiphenyls (PCBs), which adversely affect human fetal and infant development, are endocrine disrupter and cause neurological disorders. They may also be carcinogenic. It is not known whether these effects are due to whole PCBs or to its metabolites, produced by the human gastrointestinal system primarily the liver and/or by intestinal microbes such as Clostridium sp. The available data show that <i>Clostridium perfringens</i>, the most prominent species of Clostridium occurs in the human gut. <i>C. beijerinckii i</i>s a special type of Clostridium present in the gut of autistic children with late onset autism. Since mixed cultures are better PCB metabolizers than single cultures, mixed cultures of Clostridium were used in this work. The first step in PCB degradation is the removal of the chlorine atoms and then the breaking open of the phenyl ring leading to the final degradation product: CO<sub>2</sub>. In this study, GC-MS analyses were done to examine the effect of Clostridium sp. on PCB-153 and PCB-77 and the metabolites obtained with Clostridium sp. therein. In this paper, we report that the unlike human liver cells which cannot produce any PCB metabolites. Mixed Clostridium spp. can degrade these PCBs. Clostridium spp. and were able to dechlorinate PCB 153 (hexachlorobiphenyl) to pentachlorobiphenyl and PCB 77 (tetrachlorobiphenyl) to trichlorobiphenyl. Despite considerable absorption of PCB 153 (40%) and PCB 77 (50%) in 30 minutes and 1.5 hours respectively by human liver (HepG2) cells, they can not dechlorinate PCBs. It has been observed that slight differences in chemical structures of PCBs such as coplanar (PCB-77) vs. non-coplanar (PCB-153) has significant metabolic effects.
Inter‐subject and ethnic differences in paracetamol metabolism. (1986)

The 24 h urinary excretion of paracetamol and its metabolites following a single oral dose of 1.5 g was compared in 111 Caucasians (Scotland), 67 West Africans (Ghana) and 20 East Africans (Kenya). The fractional recovery of the mercapturic acid and cysteine conjugates of paracetamol was 9.3% in the Caucasians compared with only 5.2% and 4.4% in the Ghanaians and Kenyans respectively (P = less than 0.0005). This probably indicates markedly reduced metabolic activation of paracetamol in the Africans. There were no ethnic differences in the sulphate conjugation of paracetamol, but the mean fractional recovery of the glucuronide conjugate in Caucasians (54%) was significantly less than in the Africans (58%). The sulphate conjugation of paracetamol was increased and glucuronide conjugation reduced in Caucasian females compared with males. A similar trend was seen in the Ghanaians but there were no other significant sex differences. The range of intersubject variation in the metabolic activation of paracetamol was sixty fold compared with only a three fold variation in glucuronide and sulphate conjugation. This has important implications for susceptibility to paracetamol hepatotoxicity following overdosage especially in a small subgroup showing extensive metabolic activation. These ethnic differences in paracetamol metabolism may be related to genetic or environmental factors including differences in diet and protein intake.

Designing hypermedia applications (1994)

We describe a step-by-step methodology for the design and construction of hypermedia applications and illustrate our approach using a small application. The Relationship Management Design (RMD) methodology begins with a data model of the application domain and proceeds through the design of the hypertext network, user interface and run-time dynamics finally concluding with the construction and testing of the target hypermedia system. Our ultimate objective is to use the RMD approach as the basis for the construction of computerized tools to support the design and development of hypermedia applications.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Tools and techniques to minimize shock and vibration to the bottom hole assembly (2014)

When drilling a well there is a risk of serious damage caused by drillstring vibrations. Shock and vibration are identified as a cause of premature failure on drill bit and components in the bottom hole assembly (BHA), resulting in lost time for operators and costing service companies several millions in repair each year. The expenditures incurred by drillstring vibrations include reduced rate of penetration (ROP), tripping and poor drilling performance. Currently, several tools and techniques are used in the attempt to minimize shock and vibration. For vibration mitigation to be more effective in the future, the most effective tools and techniques must be designated, implemented and improved.\nThe main objectives of this thesis are to give an insight into the main vibration problem and determine effective mitigation tools and techniques, with regards to the BHA design, which can minimize shock and vibration, and improve the drilling performance in the future. A particular focus was given to anti-vibration tools, and vibration prevention in underreamer applications. The thesis is divided into four main parts; theory on drillstring vibrations, evaluation of various tools and techniques for vibration mitigation, including supplier input, a performance analysis of the Anti Stick-slip Technology (AST) and finally a discussion and conclusion part. Several field case studies are presented to illustrate how the tools and techniques can reduce the risk of detrimental vibrations.\nThe work is based on literature reviews and is substantiated by comparative field experiences. Additional information was acquired through conversations with Statoil, the directional drilling suppliers and tool suppliers. These conversations proved highly valuable and resulted in several proposed tools and techniques that should be considered when designing the BHA.\nThe thesis revealed that BHA design awareness can lead to huge advancements in terms of minimizing shock and vibration. Roller reamers should be added to the assembly if high stick-slip levels are expected or if the stabilizers experience extensive friction. Anti-vibration tools, such as AST and Frank´s Harmonic Isolation (HI) tool should be considered, as field experience indicates that these tools can reduce the vibration level. The results of the AST performance analysis indicated a 21% increase in ROP for runs including the tool. For underreamer operations a great potential exists in placing an expandable stabilizer above the underreamer. Another BHA alteration that should be considered is tapered stabilization, which can lead to fewer twist-offs in large hole sections. In the future, the industry must be willing to make changes in order to minimize shock and vibration. A constant push towards better procedures and innovative technology is needed.
