description: Infinitely many particles of two types ("plus" and "minus") jump randomly along the one-dimensional lattice $\mathbf{Z}_{\varepsilon}=\varepsilon\mathbf{Z}$. Annihillations occur when two particles of different time occupy the same site. Assuming that at time $t=0$ all "minus" particles are placed on the left of the origin and all "plus" particles are on the right of it, we study evolution of $β_\varepsilon(t)$, the boundary between two types. We prove that in large density limit $ε\to 0$ the boundary $β_\varepsilon(t)$ converges to a deterministic limit. This particle system can be interpreted as a microscopic model of price formation on economic markets with large number of players.

description: Nowadays we are often faced with huge databases resulting from the rapid growth of data storage technologies. This is particularly true when dealing with music databases. In this context, it is essential to have techniques and tools able to discriminate properties from these massive sets. In this work, we report on a statistical analysis of more than ten thousand songs aiming to obtain a complexity hierarchy. Our approach is based on the estimation of the permutation entropy combined with an intensive complexity measure, building up the complexity-entropy causality plane. The results obtained indicate that this representation space is very promising to discriminate songs as well as to allow a relative quantitative comparison among songs. Additionally, we believe that the here-reported method may be applied in practical situations since it is simple, robust and has a fast numerical implementation.

description: Diuron is a phenylurea herbicide compound amply used in agriculture to control a wide variety of annual and perennial broadleaf and grass weeds, algae, and mosses. The aim of the present study was to evaluate the genotoxicity of diuron in the wing spot assay of Drosophila melanogaster after metabolic activation of an aqueous extract from the roots of Zea mays treated with different concentrations of the herbicide. Bentazone was used as positive control. The wing spot assay that assesses for somatic mutation and recombination events was carried out with standard (ST) and high-bioactivation (HB) crosses given chronic treatment to third instar larvae. Results showed that larvae treated with the aqueous extracts caused a similar positive response in both crosses.

Stability of a 2-dimensional Mathieu-type system with quasiperiodic coefficients
Creators: name: Waters, Thomas
Publisher: name: arXiv
Year: 2012
Subjects: subject: Dynamical Systems (math.DS)
subject: FOS: Mathematics

description: In the following we consider a 2-dimensional system of ODE's containing quasiperiodic terms. The system is proposed as an extension of Mathieu-type equations to higher dimensions, with emphasis on how resonance between the internal frequencies leads to a loss of stability. The 2-d system has two `natural' frequencies when the time dependent terms are switched off, and it is internally driven by quasiperiodic terms in the same frequencies. Stability charts in the parameter space are generated first using numerical simulations and Floquet theory. While some instability regions are easy to anticipate, there are some surprises: within instability zones small islands of stability develop, and unusual `arcs' of instability arise also. The transition curves are analyzed using the method of harmonic balance, and we find we can use this method to easily predict the `resonance curves' from which bands of instability emanate. In addition, the method of multiple scales is used to examine the islands of stability near the 1:1 resonance.

Interstellar dust processes

description: Interstellar dust in the foreground of bright point sources will scatter X-rays over arcminute scales, producing a diffuse halo image. The scattering halo intensity is strongly sensitive to the dust grain size distribution, spatial distribution, and composition of dust on the sight line. Currently, Chandra's spatial resolution makes it the best detector available for studying X-ray scattering halos from the diffuse ISM. A Chandra successor with similar resolution but larger effective area will lend a greater opportunity to study scattering echoes from low column densities of the diffuse interstellar or intergalactic medium. More importantly, the combination of high resolution spectroscopy with imaging is uniquely suited to studying the composition of dust grains. At soft energies in particular, the spectrum of scattered light is likely to have significant features at the 0.3 keV C-K and 0.5 O-K photoelectric absorption edges. This direct probe of ISM dust grain elements will be important for i understanding the relative abundances of graphitic grains or PAHs versus silicates, and ii measuring the depletion of gas phase elements into solid form.

description: We propose a new regime of minimal QCD axion dark matter that lies between the pre- and post-inflationary scenarios, such that the Peccei-Quinn (PQ) symmetry is restored only on sufficiently large spatial scales. This leads to a novel cosmological evolution, in which strings and domain walls re-enter the horizon and annihilate later than in the ordinary post-inflationary regime, possibly even after the QCD crossover. Such dynamics can occur if the PQ symmetry is restored by inflationary fluctuations, i.e. the Hubble parameter during inflation $H_I$ is larger than the PQ breaking scale $f_a$, but it is not thermally restored afterwards. Solving the Fokker-Planck equation, we estimate the number of inflationary e-folds required for the PQ symmetry to be, on average, restored. Moreover, we show that, in the large parts of parameter space where the radial mode is displaced from the minimum by de Sitter fluctuations, a string network forms due to the radial mode oscillating over the top of its potential after inflation. In both cases we identify order one ranges in $H_I/f_a$ and in the quartic coupling $\lambda$ of the PQ potential that lead to the late-string dynamics. In this regime the cosmological dark matter abundance can be reproduced for axion decay constants as low as the astrophysical constraint $O(10^8)$ GeV, corresponding to axion masses up to $10^{-2}~{\rm eV}$, and with miniclusters with masses as large as $O(10)M_\odot$.

description: Excerpts from the report: This study evaluates the relative sales effectiveness of four different promotional techniques as used by an agricultural promotion organization. The comparative effectiveness of the techniques is determined in terms of the estimated sales gain per dollar spent for each. Also examined is the nature and extent of retailer support for these techniques and the individual and joint contribution to sales of pears of such retail merchandising practices as prices, display space, and newspaper advertisement space. Cooperative research with the Oregon-Washington-California Pear Bureau was conducted in 75 food supermarkets in 5 cities over a 20-week period to evaluate the relative sales effectiveness of 4 promotional techniques for winter pears. Techniques tested in a controlled experiment were: (1) Special point-of-purchase displays using in-store promotional materials; (2) store demonstrations in which taste samples of pears were given to customers along with recipe folders suggesting varied uses of pears; (3) dealer contests with cash prizes; and (4) a media advertising program of low intensity. Control periods of no advertising or merchandising support by the Pear Bureau were used for comparison.

description: We report the discovery of a giant radio halo in the galaxy cluster RXC J1514.9-1523 at z=0.22 with a relatively low X-ray luminosity, $L_{X \, [0.1-2.4 \rm \, kev]} \sim 7 \times 10^{44}$ erg s$^{-1}$. This faint, diffuse radio source is detected with the Giant Metrewave Radio Telescope at 327 MHz. The source is barely detected at 1.4 GHz in a NVSS pointing that we have reanalyzed. The integrated radio spectrum of the halo is quite steep, with a slope α= 1.6 between 327 MHz and 1.4 GHz. While giant radio halos are common in more X-ray luminous cluster mergers, there is a less than 10% probability to detect a halo in systems with $L_X \ltsim 8 \times 10^{44}$ erg s$^{-1}$. The detection of a new giant halo in this borderline luminosity regime can be particularly useful for discriminating between the competing theories for the origin of ultrarelativistic electrons in clusters. Furthermore, if our steep radio spectral index is confirmed by future deeper radio observations, this cluster would provide another example of the recently discovered population of ultra-steep spectrum radio halos, predicted by the model in which the cluster cosmic ray electrons are produced by turbulent reacceleration.

Diversity, Coding, and Multiplexing Trade-Off of Network-Coded Cooperative Wireless Networks

description: In this paper, we study the performance of network-coded cooperative diversity systems with practical communication constraints. More specifically, we investigate the interplay between diversity, coding, and multiplexing gain when the relay nodes do not act as dedicated repeaters, which only forward data packets transmitted by the sources, but they attempt to pursue their own interest by forwarding packets which contain a network-coded version of received and their own data. We provide a very accurate analysis of the Average Bit Error Probability (ABEP) for two network topologies with three and four nodes, when practical communication constraints, i.e., erroneous decoding at the relays and fading over all the wireless links, are taken into account. Furthermore, diversity and coding gain are studied, and advantages and disadvantages of cooperation and binary Network Coding (NC) are highlighted. Our results show that the throughput increase introduced by NC is offset by a loss of diversity and coding gain. It is shown that there is neither a coding nor a diversity gain for the source node when the relays forward a network-coded version of received and their own data. Compared to other results available in the literature, the conclusion is that binary NC seems to be more useful when the relay nodes act only on behalf of the source nodes, and do not mix their own packets to the received ones. Analytical derivation and findings are substantiated through extensive Monte Carlo simulations.

The effectiveness of male sexism-confronter role models in encouraging men’s sexism confronting intentions
Creators: name: Cultice, Rachel A.
Publisher: name: No Publisher Supplied
Year: 2022

description: Prejudice confrontations are an important prejudice reduction strategy. Because men’s confrontations are effective (e.g., Ratner & Miller, 2001) and perceived positively (e.g., Dickter et al., 2012; Gervais & Hillard, 2014; Vaccarino & Kawakami, 2020), it is important to increase men’s willingness to engage in sexism confrontations. The present research suggests that exposing men to a likable male sexism-confronter role model will increase men’s likelihood of confronting sexism themselves, specifically hypothesizing that when men who are low in gender system justification are exposed to a male confronter role model, they will likely emulate him (i.e., confront sexism themselves) because they will perceive him as gender typical (i.e., high on agency, low on weakness). Across two studies, men (total N = 612) who perceived a male sexism-confronter role model to be gender typical were more likely to (1) like the sexism-confronting role model and (2) report higher sexism-confronting intentions in different contexts: in Study 1, male participants evaluated actual male sexism-confronter role models who had posted Tweets in support of the #MeToo Movement, and in Study 2, male participants evaluated a fictional male role model who confronted a plausibly sexist member of a group chat. Further, as demonstrated by Study 1 results, gender system justification (Jost & Kay, 2005) plays a role in this equation by influencing men’s perceptions of the role model as gender deviant, and consequently, as unlikable. Counter to hypotheses, economic system threat (experimentally manipulated; Kay et al., 2009; Rudman et al., 2012b) didn’t impact male participants’ perceptions of the role model’s gender typicality in Study 2. Exploratory analyses incorporating constructs of masculinity were also tested as predictors of perceived role model gender typicality and likability in both Studies 1 and 2. Implications, limitations, and future directions are discussed.

NAVIGATING ASSESSMENT IN THE DIGITAL REALM: EXPERIENCES OF EDUCATORS IN A DISTANCE LEARNING ENVIRONMENT
Creators: name: Dr. MARTIN L. NOBIS, JR. EDD
Publisher: name: Zenodo
Year: 2023
Subjects: Authentic Assessment, Educational Measurement, Remote Learning.

description: Abstract
In the era of digital learning, assessment has become a crucial aspect of distance education. This study explores the experiences of educators in a teacher education institution (TEI) as they navigate assessment in a distance learning environment. The research aims to investigate the assessment tools used by teachers, identify positive and negative experiences, address challenges faced by faculty, and propose ways to enhance assessment in distance learning. The findings reveal that essay-type, project-based assessments, and performance tasks are commonly used, while rearrangement and analogy assessments are less frequent. Positive outcomes include the development of technology skills, improved teaching strategies, and enhanced student habits. However, negative effects include issues concerning the reliability and validity of assessments, academic dishonesty, dependence on technology, and excessive workloads. To address these challenges, this study recommends administering authentic assessments, valid and reliable evaluations, regular monitoring, and effective time management. These strategies can help educators in TEIs ensure the effectiveness and reliability of assessments in a distance learning environment.
The Influence of storytelling on customers' willingness to pay for regional foods
Creators: name: Soller, Gianfranco
Publisher: name: ZHAW Zürcher Hochschule für Angewandte Wissenschaften
Year: 2024
Subjects: 658.8: Marketingmanagement

description: Over the last few years, there has been an increasing consumer trend towards buying organic and regional food. However, since these products are often more expensive than those from industrial producers, they are at a competitive disadvantage. From a marketing perspective, the use of storytelling seems to be a promising technique for such products, as it allows the uniqueness of the products to be conveyed on an emotional level, thus establishing a profound relationship between producer and customer.
This thesis examines the influence of storytelling as a marketing instrument on regional foods. Its aim is to find out to what extent storytelling affects regional producers in terms of producer and product perception, purchase intention and customers' willingness to pay. In this context, both sales in physical stores and online shops are examined. To accomplish the research objectives, a quantitative research method was applied. To this end, the current state of research on storytelling was first documented in a literature review. Subsequently, an experiment was conducted to collect and analyze empirical data.
The analysis of the collected data shows that storytelling partly has a positive effect on the perception of producers, however, beyond that no significant effect on the purchase intention and the willingness to pay has been observed. The results suggest that the transformation of information through a story has at least in the short term no advantage over an emotionally triggering traditional advertisement. Nevertheless, the results of this study still have important implications for regional producers. They show that an emotional bond with customers, leading to an increased perception of producers and an increased willingness to buy, is a key element in marketing – regardless of whether this is achieved through storytelling or other marketing techniques. Further research should focus on the specific effect of storytelling methodology and the long-term effect of storytelling on customer loyalty in order to further deepen and apply the insights obtained in this study.
Kommunikationsstrategien für nachhaltige Produkte : ein Blick auf die Wirkung von Buzzwords auf die Wahrnehmung

description: Das Thema Nachhaltigkeit wird sowohl für Konsument:innen als auch Unternehmen immer wichtiger. Konsument:innen suchen zunehmend nach nachhaltigen Produkten. Unternehmen erkennen diesen Trend und versuchen, Konsument:innen mit geeigneten Kommunikationsstrategien zum Kauf ihrer nachhaltigen Produkte zu motivieren. Mit der Zunahme der Kommunikation von nachhaltigen Produkten steigt jedoch auch der Einsatz vager, falscher oder irreführender Nachhaltigkeitsaussagen. Unternehmen befinden sich deshalb in einem Spannungsfeld zwischen Greenwashing und Greenhushing. Dabei ist unklar, wie nachhaltige Buzzwords auf die Wahrnehmung der Konsument:innen wirken und wie Unternehmen diese effektiv und glaubwürdig in die Kommunikation nachhaltiger Produkte integrieren können. Diese Arbeit untersucht deshalb die Wirkung von Buzzwords auf die Wahrnehmung und Glaubwürdigkeit von nachhaltig beworbenen Produkten. Damit leistet sie einen wichtigen Beitrag zur noch wenig vorhandenen Literatur über die Anwendung von nachhaltigen Buzzwords.
Basierend auf einer umfassenden und systematischen Literaturanalyse veranschaulicht eine empirische Untersuchung durch ein Online-Experiment im Between-Subjects-Design mit zwei Experimentalgruppen (generische und konkrete Buzzwords) und einer Kontrollgruppe (keine Buzzwords) die Wirkung von Buzzwords. Die quantitative Auswertung mittels Varianz- und Regressionsanalyse von 163 Proband:innen aus dem deutschsprachigen Raum zeigt, dass Buzzwords die Wahrnehmung und Glaubwürdigkeit signifikant beeinflussen. Konkrete Buzzwords wie «100% biologische Inhaltsstoffe» haben dabei einen positiveren Effekt als generische Buzzwords wie «biologisch», wobei nur die höhere Wirkung auf die Wahrnehmung signifikant ist. Ausserdem mediiert die Glaubwürdigkeit die Beziehung zwischen Buzzwords und der Wahrnehmung.
Die Erkenntnisse aus der Theorie und Empirie liefern konkrete Handlungsempfehlungen. Eine effektive Kommunikation von nachhaltigen Produkten enthält konkrete, einfache, glaubwürdige, authentische, vertrauenswürdige, transparente und überprüfbare Botschaften. Diese Kommunikation muss nachrichten-, unternehmens- und zielgruppenspezifisch erfolgen. Unternehmen können hierfür konkrete Buzzwords nutzen, die transparente, überprüfbare und somit glaubwürdige Informationen liefern und die Gefahr von Greenwashing reduzieren. Um die Wirkung von Buzzwords zu vertiefen und generalisieren, bedarf es zukünftiger Forschung. So können der Arbeit zu Grunde liegende Limitationen beseitigt werden, die Auswirkungen auf das tatsächliche Kaufverhalten von Konsument:innen analysiert und die Transformation zu einem nachhaltigeren Konsum gelingen.

description: In this work, a novel citrate stabilised electroless bath was developed and the process parameters (concentrations of nickel, reducing agent, and stabiliser) were optimised to achieve the maximum hardness in the ENi-B deposit on 7075-T6 aluminium alloy, using the back-propagation neural network (BPNN), Box–Behnken design (BBD), simulated annealing (SA) and genetic algorithm (GA). The effect of independent variables on dependent variable was modelled using the BPNN and BBD. The models were assessed for their significance using the coefficient of determination (R2) and mean squared error (MSE). The MSE and R2 of 34.18 and 0.9852 were obtained for BPNN model against 20.48 and 0.9911 for BBD, which proved that the BBD fits well to the experimental data. The optimum nickel ion, reducing agent and stabiliser concentrations of 29.86, 0.77 and 30.92 g L−1 were obtained from BBD for the maximum hardness of 592 HV. The local optimum values obtained from BBD were compared with global optimisation techniques, SA and GA, and the values were validated through experiments carried out in triplicate. The maximum hardness from local and global optimisation techniques was identical, with negligible change in the values of optimised process parameters. X-ray diffraction and scanning electron microscopy methods were used to examine the elemental composition and surface morphology, respectively, before and after heat treatment.

These data include the radioactive decay constant and half-life.  Measurement data from real observations including Nevada underground nuclear test and Fukushima accident debris are also used. Appropriated calculation algorithms describing the radioactive evolution of the isotopes in consideration are used to evaluate the change over time of the radioxenon isotopic activity ratios. It appears that an isotopic activity of 1 million Tetra Becquerel (TBq) was reached by Xe135 two weeks after the explosion.

description: In the present study, Al/Fe core–shell particles were successfully synthesised by electroless deposition of iron on aluminium particles. The process variables were investigated and optimised to achieve maximum deposition efficiency. These variables, including chemical composition parameters (molar ratios of salt/reducing agent, salt/complexing agent and pH) and process parameters (particle size, temperature and time) were optimised by using the Taguchi method. The chemical composition of iron deposited aluminium particles, their morphology and coating quality were characterised by helium gas pycnometry, scanning electron microscopy, energy-dispersive spectroscopy and X-ray diffraction. The results revealed that, by using the optimised bath chemical composition and optimised process parameters, a maximum of 28.91% iron deposition on aluminium particles can be obtained within 20 min.

description: In this paper, joint transceiver design for dual-hop amplify-and-forward (AF) MIMO relay systems with Gaussian distributed channel estimation errors in both two hops is investigated. Due to the fact that various linear transceiver designs can be transformed to a weighted linear minimum mean-square-error (LMMSE) transceiver design with specific weighting matrices, weighted mean square error (MSE) is chosen as the performance metric. Precoder matrix at source, forwarding matrix at relay and equalizer matrix at destination are jointly designed with channel estimation errors taken care of by Bayesian philosophy. Several existing algorithms are found to be special cases of the proposed solution. The performance advantage of the proposed robust design is demonstrated by the simulation results.

Ni-impurity effects on the superconducting gap of La$_{2-x}$Sr$_{x}$CuO$_4$ studied from the magnetic field and temperature dependence of the electronic specific heat

description: The magnetic field and temperature dependence of the electronic specific heat $C_{\rm el}$ have been systematically investigated in $\rm La_{2-{\it x}}Sr_{\it x}Cu_{1-{\it y}}Ni_{\it y}O_4$ (LSCNO) in order to study Ni-impurity effects on the superconducting (SC) gap. In LSCNO with $x$=0.15 and $y$=0.015, the value of $γ$ ($\equiv C_{\rm el}/T$) at $T$=0 K, $γ_0$, is enhanced under the magnetic field $H$ applied along the $\bm c$-axis. The increment of $γ_0$, $Δγ_0$, follows the Volovik relation $Δγ_0$=$A\sqrt{H}$, characteristic of the SC gap with line nodes, with prefactor $A$ similar to that of a pure sample. The $C_{\rm el}/T$ vs. $T$ curve under $H$=0 shows a d-wave-like SC anomaly with an abrupt increase at $T_{\rm c}$ and $T$-linear dependence at $T$$\ll$$T_{\rm c}$, although the $γ_0$-value in the $C_{\rm el}/T$ vs. $T$ curve increases with increasing Ni concentrations. Interestingly, as the SC part of $C_{\rm el}/T$, $C_{\rm el}/T$$-$$γ_0$$\equiv$$γ_{\rm s}$, decreases in LSCNO, $T_{\rm c}$ is reduced in proportion to the decrease of $γ_{\rm s}$. These findings can be explained phenomenologically by a simple model in which Ni impurities bring about strong pair breaking at the edges of the coherent nodal part of the Fermi surface but in the vicinity of the nodes of the SC gap.

description: With first-principles DFT calculations, the interaction between graphene and SiO2 surface has been analyzed by constructing the different configurations based on α-quartz and cristobalite structures. The single layer graphene can stay stably on SiO2 surface is explained based on the general consideration of configuration structures of SiO2 surface. It is also found that the oxygen defect in SiO2 surface can shift the Fermi level of graphene down which opens out the mechanism of hole-doping effect of graphene absorbed on SiO2 surface observed in experiments.

description: We study the localization properties of non-interacting waves propagating in a speckle-like potential superposed on a one-dimensional lattice. Using a decimation/renormalization procedure, we estimate the localization length for a tight-binding Hamiltonian where site-energies are square-sinc-correlated random variables. By decreasing the width of the correlation function, the disorder patterns approaches a $δ$-correlated disorder, and the localization length becomes almost energy-independent in the strong disorder limit. We show that this regime can be reached for a size of the speckle grains of the order of (lower than) four lattice steps.

Responsible Conduct Of Research In The Changing Landscape Of Science

description: Responsible Conduct of Research (RCR) is a concept that encompasses both good and bad behaviour in the scientific domain. RCR has been coined in numerous statements and guidelines. There are also a variety of national approaches to handling cases of alleged and confirmed research misconduct. Many of them rest on the principle of academic autonomy and are based on self-regulation.

The landscape of scientific research is changing due to digitalization. Some even call it  a paradigm shift. Concepts such as Science 2.0 and eScience refer to the new technical possibilities digitalization is providing for scientific research. Open Science is a movement inside the research community, that aims at making both the scientific process and scientific knowledge more transparent and accessible in the digital domain. I argue that the key documents defining RCR and it's breaches were created with the "Science 1.0" in mind: for a world where research is conducted using more or less local and institution specific infrastructures, that are usually closed for outsiders and where research processes are mostly kept private. Do the RCR guidelines need to be updated and if so, how, is one of the questions I aim at answering in my dissertation.

I ask also what effect do the RCR guidelines and policies have? How have they come to being, whose voice speaks in them? How adaptable are they to changes in the scientific landscape? I approach these questions through a series of case studies:

	Forming and implementing RCR bottom-up: RCR in the context of open research collaboration, cases Polymath Project, NMR Lipids blog and SOMUS project
	Forming RCR top-down: the case of the Finnish Advisory Board on Research Integrity and its RCR guideline
	Implementing RCR top-down: the case of the Finnish research community and its process for handling suspected research misconduct

I am committed to the principles of Open Science and have adopted an open-by-default attitude towards the outputs of my research. Since a significant part of my data is non-anonymized interview data, being open requires sensitivity and thorough reflection concerning ethical issues. There is very little precedent in open qualitative non-anonymized human data, meaning that there are many issues to be tackled. For example according to the Finnish Data Protection Ombudsmans interpretation of the Finnish law, so called broad consent given by research subjects to use data related to them for unspecified further research, is not legally valid. This makes it currently impossible for me to archive and share my data in Finland. I am planning on challenging this interpretation which, if allowed to stand, will significantly hinder researchers of contemporary history from participating in the open data community and its discussions.

description: Glucose-6-Phosphate Dehydrogenase (G6PD) deficiency is the commonest cause of neonatal jaundice in Malaysia. Recently, OSMMR2000-D G6PD Assay Kit has been introduced to quantitate the level of G6PD activity in newborns delivered in Universiti Kebangsaan Malaysia Medical Centre (UKMMC). As duration of sample storage prior to analysis is one of the matters of concern, this study was conducted to identify the stability of G6PD enzyme during storage. A total of 188 cord blood samples from normal term newborns delivered at UKMMC were selected for this study. The cord bloods samples were collected in ethylene-diamine-tetra-acetic acid (EDTA) tubes and refrigerated at 2-8 °C. In addition, 32 out of 188 cord blood samples were spotted on chromatography paper, air-dried and stored at room temperature. G6PD enzyme activities were measured daily for 7 days using the OSMMR2000-D G6PD Assay Kit on both the EDTA blood and dried blood samples. The mean value for G6PD activity was compared between days of analysis using Student Paired T-Test. In this study, 172 out of 188 cord blood samples showed normal enzyme levels while 16 had levels corresponding to severe enzyme deficiency. The daily mean G6PD activity for EDTA blood samples of newborns with normal G6PD activity showed a significant drop on the fourth day of storage (p < 0.005) while for samples with severely deficient G6PD activity, significant drop was seen on third day of storage (p = 0.002). Analysis of dried cord blood showed a significant reduction in enzyme activity as early as the second day of storage (p = 0.001). It was also noted that mean G6PD activity for spotted blood samples were lower compared to those in EDTA tubes for all days (p = 0.001). Thus, EDTA blood samples stored at 2-8 °C appeared to have better stability in terms of their G6PD enzyme level as compared to dried blood samples on filter paper, giving a storage time of up to 3 days.
