▼ Abstract
Wool sample collected from thirteen Arraiolos tapestries from the 17th – 19th century belonging to the National Museum of Ancient Art ( Lisboa, Portugal) collection were analysed to identify the natural dyes and mordants used in their making. Weld, indigo, spurge flax, brazilwood, madder and cochineal were identified in the fibres. Alum was the most commonly used mordant, but the presence of iron and zinc was also detected in some
samples.
Contemporary dyed fibres were used to evaluate the available methodologies for dye extraction from wool fibres . A procedure with Na2 EDTA in water /DMF (1.1, v/v) proved to be the most efficient for recovering the different choromophores.
The Influence of mordant metal ion (aluminium, iron and cooper ) and dyeing technique on the fibre hue and photodegradation was studied in contemporary wool
samples dyed with madder r brazillwood . Colour hue was strongly influenced by deying methodology and alum mordanted fibres showed the poorest lightfastness.

▼ Pathogenic bacteria are responsible for millions of
deaths every year with an estimated mortality of 70 million people
by 2010 for Mycobacterium tuberculosis alone. Novel methods for
identification of bacterial species in hosts, urban environments,
water sources and food stuffs are required to advance diagnosis and
preventative medicine. Detection of bacterial species in
environmental
samples is a complex task since large numbers of
bacteria are present and are resistant to culturing. Therefore, the
genetic content of the entire sample has to be analysed
simultaneously and this constitutes a metagenomic sample.
Commonly-used methods of bacterial identification focus on
detection of specific genomic regions to determine species.
Currently only one percent of a metagenomic sample can be used for
identification employing phylogenetic markers. This method is
highly inefficient. The search for more widespread markers within
each genome is essential to improve detection methods. Also, modern
sequencing technologies used in these environments have short read
lengths which prove difficult to assemble e.g. repeats can lead to
incorrect assembly. The use of overrepresented oligonucleotides
provides a solution to both of these difficulties. Overrepresented
oligonucleotides (8-14bp in length) are utilised to differentiate
between species based on observed frequency of occurrence rather
than presence or absence. They occur throughout the genome thereby
increasing genomic coverage. Furthermore, overrepresented
oligonucleotides can be easily identified in a raw metagenomic
sample, bypassing the need for sequence assembly. Raw
oligonucleotide data was filtered, analysed and imported into a
structured database. A program, Oligosignatures, allowed for
creation of species and phylogenetic lineage specific
oligonucleotide markers dependent on the selection of species
specified by the user. For the purposes of this study, the context
of bacterial identification in an unknown environment was selected.
A similarity trial was then executed to determine if strains of the
same species can be separated from each other using overrepresented
oligonucleotides. Outcomes of this test provided a guideline for
the creation of species and lineage specific oligonucleotide
markers. Each species and lineage was therefore described by a
marker profile which consisted of representative oligonucleotide
markers. These marker profiles were then tested against artificial
and experimental data to determine their effectivity. Two
approaches were used for testing, namely Oligonucleotide frequency
analysis and Sequence read analysis. Oligonucleotide frequency
analysis focused on the identification of species dependent on the
global frequencies of marker oligonucleotides within each marker
profile. Sequence read analysis attempted to assign metagenomic
reads to a specific species dependent on the number of marker
oligonucleotides present within the read. The final database
contained 439 bacterial genomes from 22 different phylogenetic
lineages. Interpretation of…

▼ The distribution of free trial samples has long been used as a common and important promotional to create brand awareness, improve brand loyalty, and expand product category. Not only does it provide sampled customers with firsthand experience of the true quality of the product, it also generates consumer goodwill to help expedite the diffusion of new product. Despite those advantages, however, sampling can have negative impact on the firm sometimes. Not mention the expensive cost of distributing free samples, the firm also risks losing part of the demand for its commercial product when introducing the free sampling. This leads to a dilemma for business firms: What are the effects of free sample trials? Is it always good to distribute free samples? Under what conditions should a firm offer free trial samples to the market? What is the optimal way of offering a free trial? How firm performance is improved by the free sample trials? In this dissertation, we study the firm’s optimal strategy of free trials in the presence of network externality. In the first essay, we study a software monopolist and derive (a) the conditions under which free sample trials are profitable, and (b) the optimal duration of the free trial period. We consider two underlying factors favoring free trials: resolving uncertainty about the performance of the product and the network externality. On the other hand, however, those free versions may cannibalize the sales of the paid version.We examine how a monopolist software company can optimally determine the free trial period as well as the price of the paid version. We show that the firm is more profitable to offer free trials when the network externality is modest and consumers’ initial beliefs of the product quality are low. The implementation of optimal trial duration can increase the firm’s profit substantially compared to the typical 30-day scenario. In the second essay, we build an analytical model in a duopoly setting to examine the tradeoff between network effects and the cannibalization effect, and aims to uncover the conditions under which firms should introduce the free trial product. Our proposed analytical model suggests that when network externality is large, the firm is better off providing free demos with low quality to keep vertical differentiation between itself and its competitor. Although the distribution of free trial demos with a higher quality may drive the competitor out of market, the firm will suffer from a more severe cannibalization on its own demand. The third essay is a case study. We use a unique experimental design to empirically test how the online free samples have impact on immediate sales. Specifically, using the three month transaction data from a free sampling event in a Chinese online marketplace, we adopted a difference in difference approach to study how free sample impacts on sales differs in the pre and post promotion period, and how WOM interact with free sample effectiveness to influence sales.

▼ The concentrations of metals (Ba, Cd, Co, Cr, Cu, Mn, Ni, Pb, Sr, V, Zn) were investigated in soil and water
samples collected over four different sites in the southern part of Lake Nacogdoches over one year from August 2018 through June 2019. Water
samples were analyzed using the USEPA method 200.8 part 11.2 for total recoverable metals. Soil
samples were analyzed using the USEPA method 3050B for total recoverable metals. Although the total concentration gives some indication of the level of contamination, it is not enough to give information on the bioavailability or mobility of the element. A modified Tessier soil sequential extraction procedure was used to determine the speciation of metals in soil
samples. Thus, elements in soils are present in various physicochemical forms, which in turn influences its bioavailability. In this study, soil
samples were separated into five fractions: exchangeable, adsorbed, organic bonded, carbonate, residual fraction (F1-F5). The reliability of the total metal concentration from the digestion of bulk sediment were summed and compared withthe sequential extractions of the same bulk sediment for the metal concentrations of the fractions F1–F5. High recovery rates (≥ 5 mg metal/kg soil) indicate a good reliability for majority of metals studied using the sequential extraction procedure. The metal concentrations at the ppb level were determined by using inductively coupled plasma mass spectrometry (ICP-MS). The results indicate that the water
samples had Ba, Mn, and Sr at concentrations greater than 35 ppb for majority of
samples. The soil
samples had Ba, Co, Cr, Mn, Ni, Pb, V, and Zn at concentrations greater than 10 mg metal/kg soil for majority of
samples, with Ba, Mn, and V showing the highest values (greater than 60 mg metal/ kg of soil). All metal concentration was well below the WHO and EPA drinking water standards for metals and in the typical range found in natural waters.

▼ Research aimed at optimizing diagnostic laboratory
procedures is central to the development of effective bovine viral
diarrhoea virus (BVDV) control programmes. BVDV is a
single-stranded RNA virus that crosses the placenta to infect
foetuses resulting in reproductive losses due to foetal death or
persistently infected (PI) calves that usually die early in life.
Persistently infected animals are widely accepted to be the primary
reservoir of BVDV and the largest source of BVDV infection.
Persistently infected animals that survive calfhood are at risk of
developing mucosal disease in later life which is a severe and
usually fatal condition. In addition, persistently infected calves
that become replacement heifers in the herd may experience
significant morphological changes that occur in the ovaries which
can result in impaired reproductive performance. This poses
important challenges to overall animal/herd health and causes
losses to the cattle industry. Long-term storage of bovine ear
notch
samples from calves persistently infected (PI) with BVDV may
affect the ability of diagnostic assays to efficiently detect the
virus. This study assessed the effects of 1) long-term storage of
formalin-fixed
samples at room temperature to detect BVD viral
antigen with the aid of immunohistochemistry (IHC), 2a) long-term
storage of fresh ear notch
samples kept at -20°C, and 2b) long term
storage of phosphate-buffered saline (PBS) ear notch supernatant
kept at -20°C on the ability of an antigen-capture ELISA (AC-ELISA)
to detect viral antigen. Previous studies have verified 100%
sensitivity for both AC-ELISA on ear notch supernatant and
immunohistochemical testing of ear notches to detect BVDV provided
that
samples are properly collected and stored. In this study, ear
notch
samples from seven animals were subjected to prompt formalin
fixation and fresh
samples to prolonged storage at -20°C. Frozen
ear notches and ear notch supernatant yielded positive results on
AC-ELISA for the duration of the study, i.e. 6 months, and OD
values remained significantly within range. There was no
significant difference between storing fresh ear notch
samples and
PBS ear-notch supernatant at -20°C. However, positive IHC staining
on formalin-fixed ear notches started to fade away between day 17
and day 29 when stored at room temperature. We conclude that fresh
ear notches could safely be stored at -20°C for a period of 6
months for detecting BVD viral antigen at a later stage.

▼ Refractive index is an important optical parameter that exhibits the optical properties of materials. Single-Diffraction Method (SDM) and Abbe’s Refractometer Method (ARM) have been used for the measurements of refractive indices of twelve water samples collected from different surface water sources in Namibia. SDM employs a diffraction grating, rectangular glass cell and Ne-He laser emitting a monochromatic light of 632.5 nm. Refractive indices of water samples were measured without knowledge of refractive indices of the diffraction grating and the rectangular glass cell, and without measuring the angles of refraction, reflection and diffraction of the laser light. Experimental values obtained for refractive indices of the twelve water samples are presented. By comparison of refractive index values from SDM and ARM, their refractive index uncertainties values were lower than 0.1. This uncertainty error could be attributed to SDM instrument limitation error. More-over, turbidity, salinity, hydrogen ions (pH) and density values were measured for the water samples. From the statistical model, there exist non linear regression between salinity, pH and turbidity and the results from refractive indices from both methods. However, a linear correlation between SDM and ARM refractive index values was found to exist. Moreover, the correlation seems to exist between refractive index and density of water samples which is more notable in sea water samples. The root test was found to be 0.9535~1 for refractive index measurements from SDM and ARM.

▼ The use of immunohistochemistry has become commonplace in the field of cancer diagnosis. A major limitation to the ability to use this tool effectively is the time consuming tasks required for the analysis of data due to the fact that it is largely done by hand. Additionally, because of this, there is an inherent level of subjectivity in the results obtained from this process that may depend on who it is conducting the analysis. Therefore, there exists a need for a method that is able to quantify results from immunohistochemical techniques in a way that it is both time-effective and consistent in how each sample is treated.
In this study a program was developed that was able to give a quantitative analysis of DAB stained prostate cancer
samples that mimics the results obtained by the conventional manual annotation method. This program was then used further to analyze much larger
samples that would be too time consuming to analyze in the conventional way, as well as to analyze a large series of
samples generated in a tissue microarray.

▼ When astronauts travel in space, their primary health hazards are high-energy cosmic radiations from galactic cosmic rays (GCR). Most galactic cosmic rays have energies between 100 MeV and 10 GeV. For occupants inside of a space shuttle, the structural material is efficient to absorb most of the cosmic-ray energy and reduce the interior dose rate to below 1.2 mGy per day. However, the biological effects of prolonged exposure to low-dose radiation are not well understood. The purpose of this research was to examine the feasibility of constructing a low-dose irradiation facility to simulate the uniform radiation field that exists in space. In this research, we used a pre-manufactured incubator, specifically the Thermo Scientific Forma Series II Water Jacketed CO2 Incubator, to act as shielding and simulate the exterior of the space shuttle. To achieve the desired dose rate (< 1 mGy/h) inside the incubator volume, the computer code MCNPX was used to determine required source activity and distance between the shielding and source. Once the activity and distance were calculated, an experiment was carried out to confirm the simulation results. The confirmation used survey meters and thermoluminescence dosimeters (TLDs) to map the radiation field within the incubator.

▼ Dissertation for the degree of Doctor of Philosophy in Physics
Lead is a toxic element that has no biological role. To increase the knowledge of the mean lead concentrations accumulated and excreted by the organism, a study was developed to measure lead concentrations, using different atomic spectrometry techniques, in several tissues and excretions of Wistar rats. These rats were divided in two groups: one exposed to lead since foetal period, by lead acetate in drinking water, and a control group, not exposed to lead. By collecting samples of rats with different ages it was also studied the influence of age in lead concentrations. The studied organs and excretions were: iliac bone, tibia-fibula, femur, skull, liver, kidney, urine and faeces.
When conducting a study like this, the analytical techniques used the knowhow and the ability to understand the physical processes occurring are also of major relevance. In this work it was used the Energy Dispersive X-ray Fluorescence (EDXRF) technique to analyze the solid samples and the Electro Thermal Atomic Absorption Spectrometry (ETAAS) technique to analyze the urine. To carry on with the urine analysis it was developed an Ultrasound Solid-Liquid Extraction (USLE) procedure. This procedure was also applied to analyse brain samples. The Total Reflection X-ray Fluorescence (TXRF) technique was also used to study urine samples and to assess some of the results obtained with ETAAS.
In this work, several correlations between the different tissues were found. A possible evidence of pre-natal exposure was verified because the samples belonging to rats with 1 month old presented much higher mean lead concentrations than the concentrations, measured in works of other authors, of rats exposed to lead but not from foetal period. Furthermore, this study seems to corroborate that lead ingestion decreases with age, once it was measured a decrease of lead excretion by faeces with age. It was observed that lead concentration in tissues depends on the type of tissue. Mean lead concentrations measured were higher in bones (iliac, femur, tibia-fibula>skull) - hundreds of ppm, then in kidney - dozens of ppm and finally in liver on the order of ppm. The urine samples had the lowest mean lead concentrations on the order of hundreds/thousands of ppb, and faeces the highest mean lead concentrations, with values of dozens of thousands of ppm. One of the main contributions of this work was to show that lead accumulation and excretion decreases with age by plateaus in all tissues except in the kidneys.

▼ In a time of fierce global competition, where an immense amount of commercial messages reaches consumers around the clock and in every conceivable context, companies constantly seek to find new ways to reach out with their product. One way to do so, that has increased in popularity in recent years, is the use of gift bags. A gift bag may contain samples, miniature products and even products in full size, as a rule from several different brands, which the recipient receives free of charge. The gift bag is typically distributed at some form of event, such as store openings, fashion shows, theme parties and the like, and the receiver of the gift bag can then evaluate the content without any obligation to purchase. The ambition of the companies that choose to participate with their products in a gift bag is, of course, that the recipient will find their products satisfactory, and ideally, that he or she will continue to consume the brand in the future. There are numerous scientific research contributions related to the use of free samples, but very few that concern the gift bag, where a collection of samples from different sources and brands appear. The ambition of this study is to investigate how the conditions change when a free sample is exposed to competition from samples from other companies. The study has a qualitative approach, and consists of interviews with companies that use, or have used, gift bags as a marketing channel, along with an interview with a focus group consisting of people with experience of participating in various events where gift bags occur. The study concludes that marketing through the use of gift bags can have several positive effects for the participating brands. These are, for example, increased brand awareness and an increase in sales. However, it is of importance to evaluate the competing brands participating in the gift bag, as well as the context in which it will be distributed. The study shows that the size of the sample is of importance, since the receiver tends to notice more voluminous samples over smaller ones. Also, the presence of more established brands can have a positive effect on less well-known brands, as their credit will enhance the other participating products. It is important to note that this is only true for samples that are not of the same product category. If this is the case, they will instead be in direct competition with each other.

▼ We consider a Bayesian approach to the study of independence in a two-way contingency table obtained from a two-stage cluster sampling design. We study the association between two categorical variables when (a) there are no covariates and (b) there are covariates at both unit and cluster levels. Our main idea for the Bayesian test of independence is to convert the cluster sample into an equivalent simple random sample which provides a surrogate of the original sample. Then, this surrogate sample is used to compute the Bayes factor to make an inference about independence. For the test of independence without covariates, the Rao-Scott corrections to the standard chi-squared (or likelihood ratio) statistic were developed. They are ``large sample' methods and provide appropriate inference when there are large cell counts. However, they are less successful when there are small cell counts. We have developed the methodology to overcome the limitations of Rao-Scott correction. We have used a hierarchical Bayesian model to convert the observed cluster
samples to simple random
samples. This provides the surrogate
samples which can be used to derive the distribution of the Bayes factor to make an inference about independence. We have used a sampling-based method to fit the model. For the test of independence with covariates, we first convert the cluster sample with covariates to a cluster sample without covariates. We use multinomial logistic regression model with random effects to accommodate the cluster effects. Our idea is to fit the cluster
samples to the random effect models and predict the new
samples by adjusting with the covariates. This provides the cluster sample without covariates. We then use a hierarchical Bayesian model to convert this cluster sample to a simple random sample which allows us to calculate the Bayes factor to make an inference about independence. We use Markov chain Monte Carlo methods to fit our models. We apply our first method to the Third International Mathematics and Science Study (1995) for third grade U.S. students in which we study the association between the mathematics test scores and the communities the students come from, and science test scores and the communities the students come from. We also provide a simulation study which establishes our methodology as a viable alternative to the Rao-Scott approximations for relatively small two-stage cluster
samples. We apply our second method to the data from the Trend in International Mathematics and Science Study (2007) for fourth grade U.S. students to assess the association between the mathematics and science scores represented as categorical variables and also provide the simulation study. The result shows that if there is strong association between two categorical variables, there is no difference between the significance of the test in using the model (a) with covariates and (b) without covariates. However, in simulation studies, there is a noticeable difference in the significance of the test between the two models when there are…

▼ Human microbial research has become increasingly popular in biomedical areas due to the importance of role of human microbiome in human health. One purpose of studying human microbiome is to detect differentially abundant features from a limited group of subjects across biological conditions. Metagenomic analyses of the human microbial communities are extensively used for biomedical applications due to its reliable and evident comparative discoveries across more than one metagenomes when multiple communities are taken into consideration. Next-generation sequencing technology helps to detect taxonomic compositions of specific features/species contained in human microbial communities. Statistical analysis often starts by generating the Operational Taxonomic Units (OTUs) using taxonomic compositions to classify groups of closely associated human microbiomes. Oftentimes, the counts of features are observed as matched count data with excess zeros. Such data lead some differential abundance analysis methods to apply Zero-Inflated Poisson (ZIP) or Zero-Inflated Negative Binomial (ZINB) regression for modeling the microbial abundance. However, over-dispersion as well as within-
subject variation and correlation of matched count data render the standard ZIP and ZINB regression inadequate. To account for the inherent within-
subject variation and correlation, independent random effect terms are commonly included in the regressions. Therefore, a robust method that accounts the effect of matched
samples and correlated random effects while considering over-dispersion and excess zeros of count data is need for statistical analysis. In this paper, a statistical method, the two-part correlated ZINB model with correlated random effects (cZINB), is proposed for testing the matched
samples with repeated measurements.

▼ Nous décrivons une méthode pour l'analyse d'échantillons de sédiments par insertion directe dans le plasma inductif (ICP). Le mérite des nouvelles sondes préparées à partir d'un mélange d'échantillon et de poudre de graphite est évalué par l'analyse de mélanges standard à base d'oxydes métalliques et de graphite. Ces sondes sont des briquettes tenues par un panier de tungstène, et leur avantage principal est de permettre l'insertion de masses accrues d'échantillon dans le plasma sans envahir la région où le transfert d'énergie par induction est le plus efficace. Par conséquent, nous avons constaté une nette amélioration des limites de détection. Cependant, toutes nos tentatives d'analyser des sédiments avec ces sondes se sont soldées d'un échec. Il appert que de larges volumes de vapeurs de sillcium sont émis par ces échantillons, compromettant ainsi la viabilité analytique du plasma. […]
A procedure for the analysis of sediment samples by their direct insertion into an inductively coupled plasma is described. A novel probe design that consisted of a pellet pressed from a mixture of sample nd briquetting graphite was evaluated using graphite based metal oxide de arc standards. These pellets were carried into the plasma held in wire baskets. By increasing the mass of sample inserted in the plasma at once, without encroaching further in the zone where inductive coupling occurs in the discharge, this probe provided a commensurate improvement of detection limits. However, the sudden release of large quantities of silicon into the plasma's core upon decomposition of the silicate matrix of sediments seriously impaired its analytical performance. […]

The processing of lignocellulosic materials in modern biorefineries will allow for the production of transport fuels and platform chemicals that could replace petroleum-derived products. However, there is a critical lack of relevant detailed compositional information regarding feedstocks relevant to Ireland and Irish conditions. This research has involved the collection, preparation, and the analysis, with a high level of precision and accuracy, of a large number of biomass samples from the waste and agricultural sectors. Not all of the waste materials analysed are considered suitable for biorefining; for example the total sugar contents of spent mushroom composts are too low. However, the waste paper/cardboard that is currently exported from Ireland has a chemical composition that could result in high biorefinery yields and so could make a significant contribution to Ireland’s biofuel demands.
Miscanthus was focussed on as a major agricultural feedstock. A large number of plants have been sampled over the course of the harvest window (October to April) from several sites. These have been separated into their anatomical fractions and analysed. This has allowed observations to be made regarding the compositional trends observed within plants, between plants, and between harvest dates. Projections are made regarding the extents to which potential chemical yields may vary. For the DIBANET hydrolysis process that is being developed at the University of Limerick, per hectare yields of levulinic acid from Miscanthus could be 20% greater when harvested early compared with a late harvest.
The wet-chemical analysis of biomass is time-consuming. Near infrared spectroscopy (NIRS) has been developed as a rapid primary analytical tool with separate quantitative models developed for the important constituents of Miscanthus, peat, and (Australian) sugarcane bagasse. The work has demonstrated that accurate models are possible, not only for dry homogenous samples, but also for wet heterogeneous samples. For glucose (cellulose) the
root mean square error of prediction (RMSEP) for wet samples is 1.24% and the R2 for the validation set (R²val) is 0.931. High accuracies are even possible for minor analytes; e.g. for the rhamnose content of wet Miscanthus samples the RMSEP is 0.03% and the R²val is 0.845.
Accurate models have also been developed for pre-treated Miscanthus samples and are discussed. In addition, qualitative models have been developed. These allow for samples to be discriminated for on the basis of plant fraction, plant variety (giganteus/non-giganteus), harvest-period (early/late), and stand-age (one-year/older).
Quantitative NIRS models have also been developed for peat, although the heterogeneity of this feedstock means that the accuracies tend to be lower than for Miscanthus. The development of models for sugarcane bagasse has been hindered, in some cases, by the limited chemical variability between the samples in the calibration set. Good models are possible for the glucose and total sugars…

▼ Escalating expenditure on sales promotion techniques has lead to increasing concern over their effectiveness . Techniques such as product sampling and purchase incentives are widely believed to encourage new trial and purchase behaviour among non-users, but few studies have verified this belief empirically.
This thesis reports the results of three pioneering experiments that examine the effectiveness of mail-drop product samples, coupons, and cash-backs, as means of promoting new trial and purchase behaviour among non-users of three brands: a laundry detergent, an instant coffee, and a new toothpaste variant. A sample of 800 households was randomly selected and, for each product, households were assigned to one of four treatment groups: sample plus coupon, sample only, coupon only, and a control group. Trial and purchase data were obtained from 493 households after over two telephone interview waves.
The results indicated that samples achieved much higher rates of new trial and purchase behaviour than coupons. Coupons and cash-backs delivered alone were found to be ineffective means of encouraging purchase behaviour among non-users, and including them with samples only had a marginal, if any, effect on purchase behaviour.
This study has important implications for the practice of sampling and couponing. In particular, coupons may only subsidise purchases that would otherwise be made at full retail prices, which suggests that the current industry practice of providing coupons with samples may be unwarranted.

▼ Psychologische Forschung benutzt öfters Studenten als Stichprobe. Dies passiert nicht, weil Studenten jene Population sind welche erforscht wird, sondern weil Studenten leicht zu Forschungszwecken verfügbar sind. Diese Herangehensweise kann zu Problemen mit Reliabilität und externer Validität führen. Dieses systematische Review analysiert Literatur, welche Daten von studentischen Stichproben mit Daten von Nicht-Studenten vergleicht, und zieht Konklusionen, ob diese Stichproben zu denselben Ergebnissen führen. Insgesamt zeigen 31 von 51 Datensätzen, dass studentische Stichproben kein Ersatz für Nicht-Studenten sind, wohingegen 20 Datensätze zeigen, dass Daten von beiden Stichproben zu denselben Ergebnissen führen. Genauer betrachtet zeigt sich, dass es von Relevanz ist, welche Studenten für welche Nicht-Studenten Stichproben benutzt werden, wie beispielsweise ein fortgeschrittener Betriebswirtschaftsstudent für einen Manager. Weiters zeigt sich, dass in der Forschung das Problem mit studentischen Stichproben oft nicht erkannt wird, und Forscher oft nicht zwischen verschiedenen Studenten unterscheiden oder wie weit fortgeschritten diese in ihrem Studium sind.
Student samples are the sample of choice in many psychological studies. This is not because students are the actual population of interest, but because they are readily available or the result of convenience sampling. This approach might give rise to problems with reliability and external validity. This systematic review analyzes literature which compares student samples to non-student samples and draws conclusions if those samples produce the same results. Overall of 51 data sets 31 show that student samples are not appropriate surrogates for non-student samples, and in 20 cases student samples are appropriate. More specifically it shows it depends much more on which kind of student is used for which non-student sample such as a graduate business student is suitable for a manager. Also, it shows that overall most researchers don’t recognize a problem with using student samples and don’t differentiate between different students or how advanced they are.

▼ Syftet med detta arbete är att fördjupa min kunskap om hur datorn kan användas som musikaliskt instrument. Datorer kan reproducera och simulera akustiska instrument men likväl kan den även skapa elektroakustiska ljud genom synthesizer och samplers. Inom det moderna musikskapandet är datorn ett ytterst viktigt instrument där den bland annat fungerar som dokumentationsmaskin, det vill säga vår tids bandspelare. Andra användningsområden av datorn i dagens musiklandskap är i ”live-framträdanden”. Med detta arbete vill jag praktisera och fördjupa mina kunskaper om hur datorn kan användas som instrument i mitt eget musicerande. Genom dokumentation i form av loggbok, video och ljudinspelningar kommer jag att analysera min process med avstamp inom det sociokulturella perspektivet.
The purpose of this work is to deepen my knowledge of how the computer can be used as a musical instrument. Computers can reproduce and simulate acoustic instruments but still they can also create electroacoustic sounds through synthesizers and samplers. In modern music creation, the computer is an extremely important instrument where, among other things, it serves as a tape-machine, the tape recorder of our time. Other uses of the computer in today's music landscape are in "live performances". With this work I want to practice and deepen my knowledge of how the computer can be used as an instrument in my own music making. Through documentation in the form of logbook, video and audio recordings, I will analyze my process with an starting point in the socio-cultural perspective.

▼ Raman spectroscopy is a vibrational spectroscopic
technique. It gives a unique combination of non-destructive
analysis, high spatial resolution and phase characterisation. In
the current study Raman spectroscopy was used as the primary
technique during the study of chemical components in archaeological
earthenware
samples (i.e. low temperature fired clay pottery) of
South African and Chinese origin, and characterisation of iron
oxides derived from mill scale. One shard from each of the South
African archaeological sites (Rooiwal, Lydenburg, Makahane and
Graskop) was analysed by Raman spectroscopy, FT-IR spectroscopy,
X-ray fluorescence (XRF) spectroscopy and X-ray diffractometry
(XRD). The common features observed were montmorillonite
(Mg3(Si,Al)4(OH)2.4.5H2O[Mg]0.35), kaolin (Al2Si2O5(OH)5), quartz
(α-SiO2), feldspar (K- and NaAlSi3O8), hematite (α-Fe2O3), calcium
silicate (CaSiO3) and illite (KAl4(Si7AlO20)(OH)4). Gypsum
(CaSO4.2H2O) and calcium carbonates (CaCO3) were detected in
Lydenburg, Makahane and Graskop shards. Amorphous carbon was
observed in Lydenburg and Makahane shards while rutile appeared
only in Makahane shard. The Lydenburg and Rooiwal shards showed the
presence of anhydrite (CaSO4). The Chinese clay
samples
investigated by Raman spectroscopy were from the J A Van Tilburg
museum at the University of Pretoria. The large red shard was
recovered from the 1552 Portuguese shipwreck, São João, found
around Port Edward, South Africa. Four other shards (two red and
two gray) were recovered from the 1622 Portuguese shipwreck, the
São João Baptista, found around Kenton-on-Sea off the South African
coast. A 19th century Chinese teapot was also analysed. Hematite,
kaolin, quartz, amorphous carbon and aluminosilicates were observed
in all three red shards. All these components, except quartz, were
also observed in the teapot. The gray shards showed the presence of
quartz, kaolin, amorphous carbon and aluminosilicates. The pigments
identified were hematite (in red
samples) and black amorphous
carbon (in all
samples). Magnetite and goethite were precipitated
from mill scale-derived precursors in aqueous media. Hematite was
then prepared from the calcination of goethite at 750°C and
maghemite from the thermal treatment of magnetite at 200°C. The
iron oxides were characterised by Raman spectroscopy, XRD, surface
area determination and scanning electron microscopy (SEM). They
were generally composed of very small sized particles showing high
surface area values.

▼ No setor de mineração, a amostragem está presente no empreendimento mineral desde a fase da exploração até a lavra. Para diminuir a incerteza na previsão de teores, o planejamento de lavra requer adensamento da amostragem para garantir previsões acuradas e precisas. Acredita-se, que quanto maior a quantidade de amostras, maior a confiabilidade nas estimativa de teores. Na fase exploração, geralmente, a amostragem é realizada por furos de sondagem com coroas diamantadas, que é uma técnica com alto custo de execução e produz amostras com acuracidade e precisão. Nesta fase, existem poucos dados com alta qualidade. Já na fase operacional, a amostragem é realizada por outras técnicas devido a restrições orçamentárias e ao alto custo de execução da sondagem diamantada. Em geral, estas amostras possuem baixa qualidade (imprecisas e inacuradas) e não são submetidas a protocolos de controle que qualidade. Logo, nesta fase existem muitos dados com baixa qualidade com erro de vies e precisao. Esta dissertação avalia o impacto do uso de dados imprecisos no planejamento de curto prazo. Para isto, foram analisados dois bancos de dados distintos. O primeiro estudo utiliza o banco de dados exaustivo Walker Lake, que foi usado e considerado como o teor real do depósito. Inicialmente, as amostras foram obtidas a partir do conjunto de dados com espaçamento regular de 20×20 m e 5×5 m, a partir do banco de dados exaustivo. Um erro relativo de ±25% (imprecisão) e 10% de viés foram adicionados aos dados espaçados a 5×5 m (dados geológicos curto prazo) em diferentes cenários. Depois foram estudadas diferentes metodologias para incorporar a informação imprecisa nas estimativas. O segundo estudo é realizado em uma mina de ouro, com dois tipos de dados diferentes, a furos de sondagem (dados primários) e circulação reversa (dados secundários). Nestes estudos foram investigadas duas metodologias: cokrigagem e krigagem ordinária, e os dados foram utilizados para estimar blocos. As curvas teor tonelagem, análise de deriva e a classificação errônea dos blocos foram avaliadas para cada estudo. Para o banco de dados, Walker Lake, os resultados mostraram que o uso da cokrigagem ordinária estandardizada é a melhor metodologia em situações que existem dados imprecisos e enviesados, com boa correlação entre as variáveis primárias e secundárias. As estimativas produzidas são mais próximas da distribuição real dos blocos, reduzindo o erro de classificação dos blocos. Já para o banco de dados de Ouro, as amostras possuem moderada correlaçao e continuidade espacial curta para pequenas distâncias do depósito. Nesta situação, a correção da imprecisão da variável secundária utilizando a krigagem ordinária produziram melhores resultados com estimativas menos enviesadas e melhor classificação dos blocos como minério e estéril.
Decisions starting at mineral exploration through mining are based on grade block models obtained from samples. To decrease the uncertainty in the estimates, the short term mining planning requires additional sampling to ensure accurate…

▼ Methicilline Resistent Staphylococcus intermedius, MRSI, has become an increasing problem with pets. In the course 2007 the VMDC (Veterinair Microbiologische Diagnostisch Centrum) received a large number of
samples, coming from the veterinary practices all over the Netherlands, containing this Staphylococcus with the MecA- gen. In this study the aim was to investigate if MRSI is becoming the MRSA of the companion animals.
Although this question was not completely answered, a few conclusions about these bacteria came to light.
Animals with an MRSI infection contaminate their environment. To make sure the animal is completely free of MRSI, one must take multiple
samples. The peritoneum is an area in which the changes to find the MRSI is the larges. Further more, quick and aimed treatment of the infection seems to be the most effective way to reduce the contamination of the environment.

▼ Os resíduos de fármacos presentes em matrizes ambientais têm sido foco em pesquisas no mundo todo. Este tema tem sido bastante discutido devido ao fato de que fármacos são freqüentemente encontrados em efluentes de estações de tratamento de esgotos (ETE´s), águas de abastecimento público e em outras matrizes ambientais, tais como solos, sedimentos e águas naturais em concentrações na faixa de µg L-1 e ng L-1. A grande preocupação da presença de resíduos de fármacos na água são os potenciais efeitos adversos para a saúde humana, animal e de organismos aquáticos. Neste trabalho estudou-se o diclofenaco sódico, por ser um dos antiinflamatórios mais prescritos pelos médicos. O método utilizado para a extração do diclofenaco sódico de amostras de efluentes domésticos da ETE de Araraquara-SP foi à extração em fase sólida, e subseqüentemente a determinação por cromatografia líquida de alta eficiência com detector UV. O método foi validado e a recuperação foi de 94-105%. Constatou-se a presença do diclofenaco sódico nas amostras do efluente doméstico da cidade de Araraquara-SP antes e após o tratamento e as concentrações foram 2,12 e 3,52 µg L-1 na coleta feita em março e 18,0 e 22,0µg L-1 na coleta feita em setembro.
The pharmacos residues that are present in the environmental matrices has been a focus of research all over the world. This subject has been discussed because the fact that pharmacos are frequently found in effluents of sewage treatment plants (STPs), public water supply and in others environmental matrices, such as the soil, sediments and water springs in concentrations between µg L-1 and ng L-1. The biggest concern of pharmacos residues in the water are the adverse effects for the human health and the other species too. So, in this research the sodium diclofenac was studied for being the most prescribed anti-inflammatory by the doctors. The method used for the extraction of the sodium diclofenac of samples from the domestic effluent at STP-Araraquara (SP) was the extraction in solid phase, and subsequently the determination by liquid chromatography of high efficiency with UV detector. The method was validated and the recovery was of 94 to 105%. The results of the research have shown the presence of sodium diclofenac in the samples of Araraquara\'s domestic effluent before and after the treatment and the concentrations were 2,12 and 3,52 µg L-1 in the collection made in March and 18,0 and 22,0µg L-1 in the collection made in September.

▼ Lipidomics is a research field that attempts to
achieve the comprehensive analysis of the entire lipidome in a
biological system. The emergence and rapid expansion of lipidomic
studies is driven by the great advances in chromatographic
separation and mass spectrometry. For this dissertation, I have
focused on the development of analytical strategies for targeted
and quantitative lipidomics. The targeted lipid and lipid-related
compounds include bile acids (including free and conjugated forms),
sphingolipids, trimethylamine (TMA) and trimethylamine N-oxide
(TMAO) as well as conjugated linolenic acids (CLnA). Quantitative
methods were established based on liquid chromatography/ tandem
mass spectrometry (LC/MS/MS) techniques. Parenteral
nutrition-associated liver disease (PNALD) is a cholestatic liver
disease partially caused by developmental immaturity with regards
to hepatic bile acids metabolism and transport. Glucagon-like
peptide-2 (GLP-2) has been reported to be associated with improved
bile flow, and serum and histologic markers of cholestasis. A
universal method comprised of C18-based solid-phase extraction
(SPE) procedure and LC/MS/MS was developed and validated to monitor
the alterations in the bile acids compositions in piglet bile
samples in a control group compared to a GLP-2 treated group. As a
result, up to 12 different bile acids species were identified in
bile sample extracts. Bile acid quantification showed that GLP-2
therapy did improve the clinical phenotype of PNALD by altering
bile acids synthesis and transport. Chronic Lymphocytic Leukemia
(CLL) is the most common leukemia in North American and European
adults. Sphingolipid metabolism is altered in numerous cancers, but
strong evidence is still lacking to support this finding in CLL In
order to investigate the distributions of sphingolipids in both
cancerous and healthy B cells, an LC/MS/MS method along with a
single-phase extraction was established. 17 sphingolipid species
were successfully detected in the lipid extracts of B cells
collected from CLL patients (n=5) and healthy donors (n=4).
Quantitative data shows that there was an altered sphingolipid
composition (increased levels) observed in the B cells from the CLL
patients compared to those from healthy donors. Trimethylamine
(TMA) and trimethylamine N-oxide (TMAO) are metabolites of
choline-related compounds. Abnormal TMA and TMAO concentration
levels in biological materials could lead to the occurrence of
diseases, such as atherosclerosis and trimethylaminuria. A new
HILIC LC/MS/MS method with prior derivatization procedure to TMA
enables the simultaneous identification and quantification of TMA
and TMAO in mouse plasma samples in a single LC run within 5 min.
Conjugated linolenic acid (CLnA) isomers are present in high levels
in pomegranate seed oils (PSO) and tung seed oils (TSO). These
isomers are considered as health-enhancing compounds and the
conjugated unsaturation facilitates the manufacture of organic
coatings and polymers. Silver ion liquid chromatography coupled to

▼ No presente trabalho estudou-se, a concentração de bismuto total em áreas com falhas tectônicas e sua correlação com os níveis de radioisótopos de chumbo e de emissão de radônio-222. As determinações de bismuto total em diferentes solos foram realizadas por análise eletroquímica pela técnica de voltametria de redissolução anódica. Os valores de bismuto total aumentaram de acordo com o aumento da profundidade na extração do solo em estudo. Evidenciando a existência de bismuto decorrente da emanação de radônio-222 e sugerindo a existência de falhas geológicas nas áreas estudadas. Por análise estatística (ANOVA) verificou-se uma correlação da concentração de chumbo total e o nível de emissão de radônio-222 com a concentração de bismuto total. Essa correlação indica que a fonte de bismuto é proveniente da cadeia de decaimento radioativo do urânio-238 e tório-232.
In this work, the total concentration of bismuth areas with tectonic faults and their correlation and their correlation with the levels of lead radioisotopes and radon-222 emission. The determination of total bismuth in different soils were performed by electrochemical analysis using anodic redissolution voltammetry technique. The total bismuth values increased according to the depth increase in the extraction of the soil under study, evidencing the existence of bismuth due to the emanation of radon-222 and suggesting the existence of geological faults in the studied areas. Statistical analysis (ANOVA) showed a correlation between the total lead concentration and the emission level of radon-222 with the total bismuth concentration. This correlation indicates that the bismuth source is from the radioactive decay chain of uranium-238 and thorium-232.

▼ Raman spectroscopy is a vibrational spectroscopic
technique. It gives a unique combination of non-destructive
analysis, high spatial resolution and phase characterisation. In
the current study Raman spectroscopy was used as the primary
technique during the study of chemical components in archaeological
earthenware
samples (i.e. low temperature fired clay pottery) of
South African and Chinese origin, and characterisation of iron
oxides derived from mill scale. One shard from each of the South
African archaeological sites (Rooiwal, Lydenburg, Makahane and
Graskop) was analysed by Raman spectroscopy, FT-IR spectroscopy,
X-ray fluorescence (XRF) spectroscopy and X-ray diffractometry
(XRD). The common features observed were montmorillonite
(Mg3(Si,Al)4(OH)2.4.5H2O[Mg]0.35), kaolin (Al2Si2O5(OH)5), quartz
(α-SiO2), feldspar (K- and NaAlSi3O8), hematite (α-Fe2O3), calcium
silicate (CaSiO3) and illite (KAl4(Si7AlO20)(OH)4). Gypsum
(CaSO4.2H2O) and calcium carbonates (CaCO3) were detected in
Lydenburg, Makahane and Graskop shards. Amorphous carbon was
observed in Lydenburg and Makahane shards while rutile appeared
only in Makahane shard. The Lydenburg and Rooiwal shards showed the
presence of anhydrite (CaSO4). The Chinese clay
samples
investigated by Raman spectroscopy were from the J A Van Tilburg
museum at the University of Pretoria. The large red shard was
recovered from the 1552 Portuguese shipwreck, São João, found
around Port Edward, South Africa. Four other shards (two red and
two gray) were recovered from the 1622 Portuguese shipwreck, the
São João Baptista, found around Kenton-on-Sea off the South African
coast. A 19th century Chinese teapot was also analysed. Hematite,
kaolin, quartz, amorphous carbon and aluminosilicates were observed
in all three red shards. All these components, except quartz, were
also observed in the teapot. The gray shards showed the presence of
quartz, kaolin, amorphous carbon and aluminosilicates. The pigments
identified were hematite (in red
samples) and black amorphous
carbon (in all
samples). Magnetite and goethite were precipitated
from mill scale-derived precursors in aqueous media. Hematite was
then prepared from the calcination of goethite at 750°C and
maghemite from the thermal treatment of magnetite at 200°C. The
iron oxides were characterised by Raman spectroscopy, XRD, surface
area determination and scanning electron microscopy (SEM). They
were generally composed of very small sized particles showing high
surface area values.

▼ Examination of microscopic wear marks on the surface of teeth (dental microwear) provides information about the main components of an animal's diet. Inferences can be made about the diet of extinct species by comparing the dental microwear patterns of fossil samples with those of present-day groups whose diet is known. This thesis examines the dental microwear of Griphopithecus alpani, a 15 Ma fossil hominoid from the Miocene site of Pasalar in north-western Turkey. The micro wear patterns of G. alpani are compared to three extant hominoid taxa—Gorilla gorilla gorilla. Pan troglodytes verus, and Pongo pygmaeus pygmaeus. Results indicate that there is no close dietary analogue to the fossil hominoids among the extant groups. However, the analysis suggests that the diet of Griphopithecus alpani was more similar to that of Pongo, which consumes mainly fruit and the occasionally hard and unripe fruits and nuts, than to the other living hominoids examined in this study. The high percentages of pits displayed by G. alpani indicate that it was ingesting harder fruits and/or objects than the extant hominoids, and it is similar in this respect to Graecopithecus freyhergi, a Miocene hominoid from Greece. There were consistent variations in microwear patterns between the different facets examined in this study. The results of this study do not indicate variation in dental micro wear according to sex or age.
Subjects/Keywords: 551; Fossil samples; Miocene hominoid
