Key performance indicators (KPIs)

description: The project “Social network tools and procedures for developing entrepreneurial skills in PhD
 programmes” (prodPhD) aims to implement innovative social network-based methodologies
 for teaching and learning entrepreneurship in PhD programmes. The multidisciplinary teaching
 and learning methodologies to be developed will enable entrepreneurship education to be
 introduced into any PhD programme, providing students with the knowledge, skills, and
 motivation to engage in entrepreneurial activities. However, the use of the output of the
 project will depend on the nature and profile of the research or scientific field. In this context,
 key performance indicators (KPIs) form the base on which the quality and scope of the
 methodologies developed in the project will be quantified and benchmarked.
 The project’s final product will be an online tool that higher education students can use to learn
 entrepreneurship from a social network perspective. Performance measurement is one of the
 first steps of any project and involves the choice and use of indicators to measure the
 effectiveness and success of the project’s methods and results. All the KPIs have been selected
 according to criteria of relevance, measurability, reliability, and adequacy, and they cover the
 process, dissemination methods, and overall quality of the project. In this document, each KPI
 is defined together with the units and instruments for measuring it. In the case of qualitative
 KPIs, five-level Likert scales are defined to improve indicator measurability and reliability.
 The KPIs for prodPhD are divided into three main dimensions, depending on the stage of the
 project they evaluate. The three main dimensions are performance and development (which
 are highly related to the project’s process), dissemination and impact (which are more closely
 correlated with the project’s output), and overall project quality. Different sources (i.e.,
 European projects and papers) have been drawn upon to define a set of 51 KPIs classified into
 six categories, according to the project phase they aim to evaluate. An Excel tool has been
 developed that collects all the KPIs analysed in the production of this document. This tool is
 shared in the Scipedia repository.

description: The donor-acceptor type π-conjugated polymers having heterole units were prepared by the reaction of a regioregular organometallic polymer having both reactive titanacyclopentadiene and electron-donor thiophene-2,5-diyl units in the main chain with electrophiles such as diphenyltin dichloride, dichlorophenylphosphine, and diiodophenylarsine. For example, a polymer having electron-accepting phosphole unit was obtained in 54% yield whose number-average molecular weight (Mn) and molecular weight distribution (Mw/Mn) were estimated as 3,000 and 1.9, respectively. The obtained polymer exhibits a high highest occupied molecular orbital (HOMO) and low lowest unoccupied molecular orbital (LUMO) energy levels (−5.13 eV and −3.25 eV, respectively) due to the electron-donating thiophene and electron-accepting phosphole units. Reflecting upon the alternating structure of thiophene and phosphole, the polymer exhibits a band gap energy level (Eg) of 1.78 eV which is narrower than that of a derivative of poly(thiophene) (Eg = 2.25 eV).

description: We present magnetization measurements of mesoscopic superconducting niobium loops containing a ferromagnetic (PdNi) π junction. The loops are prepared on top of the active area of a micro-Hall sensor based on high mobility GaAs/AlGaAs heterostructures. We observe asymmetric switching of the loop between different magnetization states when reversing the sweep direction of the magnetic field. This provides evidence for a spontaneous current induced by the intrinsic phase shift of the π junction. In addition, the presence of the spontaneous current near zero applied field is directly revealed by an increase of the magnetic moment with decreasing temperature, which results in half integer flux quantization in the loop at low temperatures.
title: The Influence of Maturity Status on Jumping Performance of Inner London Secondary School Students

Publisher: name: The University of East London

description: Talent Detection (TDE) is a method for the identification of potentially talented athletes establishing the physical ability of an athlete without the presence of sport specific skill. TDE typically uses assessments that identify physical characteristics inherent with the given sport, with ambitions to find those with superior physical ability. These protocols are traditionally aimed at set chronological ages, as low as ten years old. However, it has been established that youths will enter the adolescent process at different ages, and will go through the process at different rates. Therefore we know that it is possible to have a selection of athletes of the exact same chronological age, with as much as a few years difference in biological age (from the onset of puberty). Maturation of athletes has been explored and a selection of non-invasive methods has been established as valid protocols for biological age assessment. This research looked to establish relationships between maturity and jumping performances across the vertical (VJ) and horizontal (HJ) jumps, both highly used assessments within TDE. 72 girls and 65 boys were assessed for maturity and performance of jumps were taken using a jump mat for VJ and a tape measure for HJ. The results concluded a strong relationship with maturity and VJ and HJ in the boys, and a very strong relationship with peak power in both VJ and HJ in the boys and girls. The limitations of this study surround the dependency on adjustment equations due to the equipment used, and the use of the prediction equation for maturity. However there is strong evidence that suggests biological age should be considered when undergoing assessments as used within TDE, to allow for fair comparison across athletes of the same chronological age, and further research needs to be done overcoming the limitations of this study.

description: The spin unpolarised to spin polarised v=2/3 phase transition is studied in narrow quantum wells. The phase transition is mapped in the filling factor (ν), density (n)-plane and is well described assuming a Image dependence of the Composite Fermion effective mass. At high currents the huge longitudinal resistance anomaly appears along the phase boundary. A model is presented that treats the current induced nuclear spin polarisation as an additional source of disorder, which drastically alters the initial domain structure present at the phase boundary. Time and current dependent measurements at constant magnetic field indicate that a large alternating Hall field is necessary to maintain the high resistance state.
A biographical study on Bukong 不空 (aka. Amoghavajra, 705-774) : networks, institutions, and identities
Creators: name: Yang, Zeng
Publisher: name: University of British Columbia
Year: 2018

description: This dissertation addresses the historical practices of the Buddhist monk Bukong, who is well known by his Sanskrit name Amoghavajra and recognized as the most important promoter of the Esoteric tradition of Vajroṣṇīṣa Yoga in medieval China. Bukong was of mixed descent, half Indian and half Sogdian, and he traveled widely throughout Asia. Spending most of his lifetime in Tang China, as a Buddhist missionary and court official, he devoted his life to combining a soteriological agenda with monastic service to the state. In this regard, his commitment was so pivotal to the Esoteric school that it gave the latter an institutional expression that distinguished it from other Buddhist traditions in China. The school thrived as vital part of the official institutions of the state and thus constituted a new mode of imperial Buddhism. Bukong’s biographical accounts became the primary context for the historical narratives and documentation of almost all events and issues related to Esoteric Buddhism at the time. Employing a wide variety of historical materials, this study presents a comprehensive biography of Bukong that has been long overdue in academia. The exploration that follows focuses on his political rise and the institutionalization of his Esoteric School in its heyday, revealing the posts held by monks as the religious functionary and official institutes provided for his yogin disciples. The success of Bukong and his school owed significantly to the political and military turbulence caused by the An Lushan rebellion. He contributed to the usurpation of Emperor Suzong and was rewarded with the imperial authorization of his Esoteric tradition and the initial institutionalization of the Esoteric practices. During the next reign, a victory over a foreign invasion widely convinced his contemporaries of the “miraculous” might of the Vajroṣṇīṣa Yoga and facilitated Emperor Daizong’s conversion into a royal yogin. The emperor’s devotion and secret association with Bukong became a powerful factor for the latter to weave an eclectic network that assembled various resources to support Buddhist institutions and projects. Bukong’s diverse achievements and social associations, however, led to the diversified perception of him in historical writings.

description: Ultrahigh-frequency (up to 24 GHz) surface acoustic waves were excited with short-period interdigital transducers and detected in GaAs/AlGaAs quantum wells with an optical scheme. We demonstrate that the transducers can be driven in a contactless fashion. Sets of two transducers permitted the coherent emission of surface acoustic waves and the creation of standing waves due to interference. The methods described offer bright prospects for finite wave-vector spectroscopy of two-dimensional electrons in a noninvasive way up to wave numbers of 106 cm–1.

description: Abstract               
This study aims to analyze and measure the causal relationship between the inflation rate and the unemployment rate in Iraq for the period 2004-2021, utilizing the Phillips curve methodology to analyze the causal relationship between inflation and unemployment rates.The study found a weak inverse relationship between the inflation and unemployment rates in Iraq during the period 2004-2021, indicating a relative decoupling of the impact between changes in inflation and unemployment. Specifically, a decrease in the unemployment rate by an average of 0.013% is associated with a 10% increase in the inflation rate. Additionally, the correlation coefficient between the variables of the study was calculated, revealing a direct relationship. Consequently, the Phillips curve could not be established for the period 2004-2021, and what is referred to as the stagflation phenomenon became apparent. This finding suggests a minor inverse relationship between the variables, which is not consistent across all the years studied, aligning with the theoretical framework of the Phillips curve and supported by the mathematical analysis of the study.

description: We present a framework to obtain photometric redshifts (photo-zs) for gamma-ray burst afterglows. Using multi-band photometry from GROND and Swift/UVOT, photo-zs are derived for five GRBs for which spectroscopic redshifts are not available. We use UV/optical/NIR data and synthetic photometry based on afterglow observations and theory to derive the photometric redshifts of GRBs and their accuracy. Taking into account the afterglow synchrotron emission properties, we investigate the application of photometry to derive redshifts in a theoretical range between z~1 and z~12. The measurement of photo-zs for GRB afterglows provides a quick, robust and reliable determination of the distance scale to the burst, particularly in those cases where spectroscopic observations in the optical/NIR range cannot be obtained. Given a sufficiently bright and mildly reddened afterglow, the relative photo-z accuracy is better than 10% between z=1.5 and z~7 and better than 5% between z=2 and z=6. We detail the approach on 5 sources without spectroscopic redshifts observed with UVOT on-board Swift and/or GROND. The distance scale to those same afterglows is measured to be $z=4.31^{+0.14}_{-0.15}$ for GRB 080825B, $z=2.13^{+0.14}_{-0.20}$ for GRB 080906, $z=3.44^{+0.15}_{-0.32}$ for GRB 081228, $z=2.03^{+0.16}_{-0.14}$ for GRB 081230 and $z=1.28^{+0.16}_{-0.15}$ for GRB 090530. Combining the response from UVOT with ground-based observatories and in particular GROND operating in the optical/NIR wavelength regime, reliable photo-zs can be obtained from z ~ 1.0 out to z ~ 10, and possibly even at higher redshifts in some favorable cases, provided that these GRBs exist, are localized quickly, have sufficiently bright afterglows and are not heavily obscured.

Characterizing the behavior of nylon actuators and exploring methods for manufacturing them to get the highest amount of output
Creators: name: Rafie Ravandi, Ali
Publisher: name: University of British Columbia
Year: 2018

description: Coiled nylon thermal actuators are polymer based artificial muscles introduced in 2014. Although there are many applications that can benefit from nylon actuators, there has not been much work on the methods of producing the actuators. To maximize the output of the actuators, various factors can be altered during the production phase. These factors are pre-anneal stretch, coiling tensile stress and annealing temperature. Results show that with a pre-anneal stretch of 70% and a coiling stress of 48 MPa, the highest amount of force generated can be reached without substantial failures. Also, it is found that the annealing temperature should be in the range of 170°C to 180°C. Annealing temperature needs to be in this range since the actuator should be above Brill transition temperature. Upon annealing in this temperature range, the actuator is fixed in its configuration, and it will not uncoil after it has been annealed. Additionally, the creep of the actuators and its effect on the output, has been studied. A model for the creep is proposed. The model consists of a Kelvin and a Maxwell model. The proposed model for the creep includes two damper elements, which account for the short term and long-term creep. The model fits the observed response well for the short-term creep, but for the long-term creep the goodness of fit decreases. Additionally, a model for active deformation of the actuator behavior as the result of changes in tensile stress is proposed. In particular, shape memory effects are added to account for load history dependence of the response. The active deformation model and the creep model are essential for developing a control system for using the actuators. The findings of this work can be used by researchers and device designers to bring the nylon actuators to real life applications.
Quantized transport in ballistic rectifiers: sign reversal and step-like output

description: Tunable ballistic rectifiers with different geometries are investigated. On standard structures with a symmetry-breaking scatterer embedded in a cross-bar geometry, we observe—apart from the usual rectification behavior—oscillations in the output characteristics that show the importance of quantum transport for the understanding of the rectification mechanism. On samples that are designed taking semiclassical and quantum transport into account, we find greatly improved rectification efficiency, accompanied, however, by a surprising reversal of the output polarity. We also observe a pronounced step-like increase in the rectified signal. All observations can be explained by a model that takes into account the interplay between classical diffusive, semiclassical, and quantum transport.
Radiative corrections to neutral pion-pair production

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We calculate the one-photon loop radiative corrections to the neutral pion-pair photoproduction process $π^-γ\to π^-π^0π^0$. At leading order this reaction is governed by the chiral pion-pion interaction. Since the chiral $π^+π^-\toπ^0π^0$ contact-vertex depends only on the final-state invariant-mass it factors out of all photon-loop diagrams. We give analytical expressions for the multiplicative correction factor $R\sim α/2π$ arising from eight classes of contributing one-photon loop diagrams. An electromagnetic counterterm has to be included in order to cancel the ultraviolet divergences generated by the photon-loops. Infrared finiteness of the virtual radiative corrections is achieved (in the standard way) by including soft photon radiation below an energy cut-off $λ$. The radiative corrections to the total cross section vary between $+2\%$ and $-2\%$ for center-of-mass energies from threshold up to $7m_π$. The finite part of the electromagnetic counterterm gives an additional constant contribution of about $1\%$, however with a large uncertainty.

description: Magnetic vortices form the ground state in micron and submicron ferromagnetic disks. By inserting artificial defects (antidots) into a submicron ferromagnetic disk, magnetic vortices can be pinned controllably thus enabling a different way for magnetic switching. We show that by inserting n antidots into a disk magnetization reversal takes place via n-1 jumps of the vortex core between neighboring antidots. This cannot only be used to establish stable two-state switching for n = 2, but also to realize a multilevel remanent state with low switching fields.

description: Peppermint essential oil (EO) is obtained by the steam distillation of the Mentha × piperita L. aerial parts; it is widely used in several fields including chewing gums, confectionary, oral hygiene products, pharmaceuticals and liquors. Most peppermint EO is nowadays produced in United States but Italy has maintained a commercial production of peppermint EO confined to a restricted area in Piedmont (Torino and Cuneo Province) dated from the 18th century. Piedmont peppermint EO is produced from a single mint variety, i.e., the Mentha × piperita L. var. Italo-Mitcham (black mint), it is considered of very high quality and characterised by freshness and long lasting sweetness. In this study, peculiar flavour characteristics of peppermint EO have been investigated by Gas Chromatography-Olfactometry (GC-O) using the Aroma Extraction Dilution Analysis (AEDA) approach. Among the compounds responsible for intense sweet, coconut, coumarin-like notes, the most intense odorant was menthofurolactone (i.e., 3,6-Dimethyl-4,5,6,7-tetrahydro-benzo[b]-furan-2(3H)-one – CAS [16642-41-4]). This trace odour-active compound belongs to p-menthane lactones family that represents a class of minor components in peppermint EO although they highly affect the overall flavour profile. The presence of menthofurolactone and related compounds (i.e., chemical signature) in different samples was confirmed by combining bi-dimensional retention data and spectral data collected at 70 and 12 eV by Comprehensive Two-Dimensional Gas Chromatography coupled to Time-of-Flight Mass Spectrometry (GC×GC-TOF MS) featuring tandem ionisation. A selection of raw peppermint EOs from different geographic origin were accurately profiled by GC×GC-TOF MS to further investigate the distribution of these key-aroma compounds and reveal diagnostic signatures of p-menthane lactones family. Piedmont peppermint EOs showed a diagnostically higher amount of this trace-odorant, and related compounds, compared to the other commercial EOs, as an evidence of its contribute to Piedmont EO rich and round flavour profile. A dedicated fingerprinting approach based on diagnostic signatures of potent odorants within specific retention windows, validate this correlation and poses solid foundation to an objective qualification of this highly valuable product.
Three-dimensional simulations of internal wave breaking and the fate of planets around solar-type stars

description: We study the fate of internal gravity waves approaching the centre of a non-rotating solar-type star, by performing 3D numerical simulations using a Boussinesq-type model. These waves are excited at the top of the radiation zone by the tidal forcing of a short-period planet on a circular, coplanar orbit. This extends previous work done in 2D by Barker & Ogilvie. We first derive a linear wave solution, which is not exact in 3D; however, the reflection of ingoing waves from the centre is close to perfect for moderate amplitude waves. Waves with sufficient amplitude to cause isentropic overturning break, and deposit their angular momentum near the centre. This forms a critical layer, at which the angular velocity of the flow matches the orbital angular frequency of the planet. This efficiently absorbs ingoing waves, and spins up the star from the inside out, while the planet spirals into the star. We also perform numerical integrations to determine the linearised adiabatic tidal response throughout the star, for solar-type stellar models with masses in the range 0.5 < m_star/M_sun < 1.1, throughout their main sequence lifetimes. The aim is to study the launching region for these waves at the top of the radiation zone in more detail, and to determine the accuracy of a semi-analytic approximation for the tidal torque on the star, that was derived under the assumption that all ingoing wave angular momentum is absorbed in a critical layer. The main conclusions are that this nonlinear mechanism of tidal dissipation could provide an explanation for the survival of all short-period extrasolar planets observed around FGK stars, while it predicts the destruction of more massive planets. This work provides further support for the model outlined in a previous paper by Barker & Ogilvie, and makes predictions that will be tested by ongoing observational studies, such as WASP and Kepler.

description: Abstract
At present, the focus of family businesses on long-term sustainability is rooted in the achievements of preceding generations. This success reflects the family's control over and inheritance of both wealth and social accomplishments. However, family businesses face challenges such as potential conflicts, emotional disruptions, differences in beliefs, and individual egos, all of which can significantly impact business continuity. Entrepreneurial knowledge sharing represents the interaction and communication between individuals and business units, contributing to a company's strategic development. This culture of knowledge sharing carries implications for enhancing relationships with company resources and serves as a means of preserving values and traditions within a family business. The aim of this research is to examine the Intergeneration Relationship Quality variable as a mediator in addressing the gap in entrepreneurial knowledge-sharing research concerning the sustainability of family businesses. The research sample comprises family business owners in the Central Java region, selected using purposive sampling techniques. The research findings indicate a positive influence on all four hypotheses.

description: We have developed a spectrum synthesis method for modeling the UV emission from the accretion disk from cataclysmic variables (CVs). The disk is separated into concentric rings, with an internal structure from the Wade & Hubeny disk-atmosphere models. For each ring, a wind atmosphere is calculated in the co-moving frame with a vertical velocity structure obtained from a solution of the Euler equation. Using simple assumptions, regarding rotation and the wind streamlines, these 1D models are combined into a single 2.5D model for which we compute synthetic spectra. We find that the resulting line and continuum behavior as a function of the orbital inclination is consistent with the observations, and verify that the accretion rate affects the wind temperature, leading to corresponding trends in the intensity of UV lines. In general, we also find that the primary mass has a strong effect on the P-Cygni absorption profiles, the synthetic emission line profiles are strongly sensitive to the wind temperature structure, and an increase in the mass loss rate enhances the resonance line intensities. Synthetic spectra were compared with UV data for two high orbital inclination nova-like CVs - RW Tri and V347 Pup. We needed to include disk regions with arbitrary enhanced mass loss to reproduce reasonably well widths and line profiles. This fact and a lack of flux in some high ionization lines may be the signature of the presence of density enhanced regions in the wind, or alternatively, may result from inadequacies in some of our simplifying assumptions.

description: In this groundbreaking paper, Author explores the concept of Recursive Purpose through the lens of Yearning-Based Infinity Mathematics (YBIM). Moving beyond traditional notions of finite goals, the paper presents a transformative view of existence as an infinite, unfolding process. By integrating insights from mathematics, philosophy, and human experience, the work introduces a dynamic framework for understanding personal growth, ethical responsibility, and collective evolution.

The paper also introduces the Recursive Human Rights Charter (RHRC), recognizing the inherent right of all individuals to grow, transform, and participate in adaptive societal systems. With applications in governance, education, and restorative justice, the recursive model challenges conventional perspectives and opens a dialogue on how we navigate uncertainty and infinite possibility.

Through a synthesis of ancient wisdom, modern science, and mathematical reasoning, Discovering Purpose invites readers to reconsider their place in the recursive fabric of existence — where every question births another, and every yearning fuels new growth.

description: Superconducting EuFe2(As0.82P0.18)2 single crystals are investigated by infrared spectroscopy in a wide frequency range. Below Tc=28K a superconducting gap forms at 2Δ_{0} = 9.5 meV = 3.8 k_B T_c causing the reflectivity to sharply rise to unity at low frequency. In the range of the gap the optical conductivity can be perfectly described by BCS theory with an $s$-wave gap and no nodes. From our analysis of the temperature dependent conductivity and spectral weight at T>T_c, we deduce an increased interband coupling between hole- and electron-sheets on the Fermi surface when $T$ approaches T_c.

description: This work deals with theoretical aspects of pulse propagation. The core focus is on extreme, few-cycle pulses in optical fibers, pulses that are strongly affected by both dispersion and nonlinearity. Using Hamil- tonian methods, we discuss how the meaning of pulse envelope changes, as pulses become shorter and shorter, and why an envelope equation can still be used. We also discuss how the standard set of dispersion coefficients yields useful rational approximations for the chromatic dispersion in optical fibers. Three more specific problems are addressed thereafter. First, we present an alternative framework for ultra- short pulses in which non-envelope propagation models are used. The approach yields the limiting, shortest solitons and reveals their universal features. Second, we describe how one can manipulate an ultrashort pulse, i.e., to change its amplitude and duration in a predictable manner. Quantitative theory of the manipu- lation is presented based on perturbation theory for solitons and analogy between classical fiber optics and quantum mechanics. Last but not least, we consider a recently found alternative to the standard split-step approach for numerical solutions of the pulse propagation equations.

description: Radio Frequency Identification (RFID) is appearing as a favorite technology for automated identification, which can be widely applied to many applications such as e-passport, supply chain management and ticketing. However, researchers have found many security and privacy problems along RFID technology. In recent years, many researchers are interested in RFID authentication protocols and their security flaws. In this paper, we analyze two of the newest RFID authentication protocols which proposed by Fu et al. and Li et al. from several security viewpoints. We present different attacks such as desynchronization attack and privacy analysis over these protocols.

The potential of increasing the use of BC forest residues for bioenergy and biofuels
Creators: name: Larock, Fraser
Publisher: name: University of British Columbia
Year: 2018

description: Groups such as the International Energy Agency have predicted that increased bioenergy and biofuels production will be needed to reduce greenhouse gas (GHG) emissions and fossil fuel use globally. British Columbia (BC) has a world-renowned forest sector and the highest percentage of third party certified sustainable forests in the world. Therefore, BC is well positioned to supply sustainable forest biomass for bioenergy/biofuels. Currently, underutilized forest residues could provide a major source of biomass for bioenergy/biofuels. However, the use of forest residues under current BC forest management standards does not fulfill some sustainability requirements defined by trade policies. Therefore, an improved sustainability verification system would support the growth of bioenergy/biofuels globally. Most forest certification systems were initially developed for traditional forest products such as lumber and pulp. In contrast, the evolving bioenergy sector uses biomass-sourcing certification standards that have limited connection to in-forest certification procedures. As a result, gaps between these certification standards challenge the potential of forest residues being used as sustainable feedstocks for the current and future bioeconomy. A partnership between forest and biomass-sourcing sustainability standards is likely, to connect GHG emissions data and other key metrics along the supply chain. The Programme of Endorsed Forest Certifications has begun developing a GHG tracking system for forest managers and is considering partnership opportunities with the Sustainable Biomass Program, a prominent wood pellet certification organization. However, there are significant economic challenges limiting the increased use of BC forest residues. To reduce the economic challenges of using forest residues, BC’s forest and climate policies need to be modified, while making sure any unintended negative stakeholder impacts are considered. The thesis work indicates that a combination of policy and economic incentives will be required for commercial-scale use of forest residues. One way to enhance forest residue use is through the use of regulatory incentives. As described in the thesis, it is likely that any increased use of BC forest residues will require significant government support via policies that will ensure the sustainable management of BC’s forest while further developing markets for the various biomaterials derived from forest residues.

description: The current-current correlator method has been used successfully to obtain very accurate results for quark masses and the coupling alpha_s. The calculations were done using Highly Improved Staggered Quarks (HISQ) and heavy-heavy meson correlators. We now extend this work to the significantly more challenging heavy-light case, reporting the first results here. The aim is to determine nonperturbative Z factors for NRQCD heavy-light currents, but first we test the method in the HISQ case where Z=1.

description: Abstract
This research presents a comprehensive exploration of the impact of modernism on Igala architecture, tracing its evolution from pre-colonial times to the contemporary era. Employing a chronological and narrative approach, the study utilized archival research, field surveys, and interviews with local professionals, indigenous elders, and environmental experts to investigate the transformative effects of modernism on Igala architecture. Although limited by unavailable population data and a vast geographical spread, historical records and engagement with the study area provide valuable insights into the interplay between modernism and Igala building practices. The arrival of European colonizers in the nineteenth century disrupted indigenous traditions, leading to a fusion of European architectural styles with traditional Igala residential designs. This research highlights the resilience of the Igala people in preserving their architectural heritage. It serves as a crucial resource for architects, historians, and cultural preservationists, emphasizing the importance of preserving indigenous architectural practices amidst rapid globalization.

description: X-ray diffraction with synchrotron radiation has been used for the first time to study chemical interaction in the MnO-ZnO system at 4.8 GPa and temperatures up to 1600 K. Above 750 K, the chemical reaction between MnO and ZnO has been observed that resulted in the formation of rock salt (rs) Mn1-xZnxO solid solutions (0.3 \leq x \leq 0.7). The lattice parameters of these solid solutions have been in situ measured at high pressure as a function of temperature, and corresponding thermal expansion coefficients have been calculated.

description: Smokers are known to have a characteristic smelling and long-lasting breath after the consumption of a cigarette. However, the responsible compounds for this malodour have not been fully explored yet. Therefore, the aim of the present study was to characterise key aroma compounds in the breath of cigarette smokers and compare the resulting aroma profile to electronic cigarette (EC) users’- and non-smokers’ (NS) breath before and after product consumption by application of aroma extract dilution analysis (AEDA) in combination with gas chromatography olfactometry (GC-O). Interestingly, the breath of cigarette smokers revealed a significantly higher intensity in the overall aroma, resulting in higher flavour dilution factors, in comparison to the breath of non-smokers or electronic cigarette users. This was predominantly caused by a high number of aroma-active pyrazines. Exhibiting an earthy, musty smell, these combustion products can still be found in breath one hour after smoking and are hypothesised to be responsible for the characteristic ‘ashtray’ smell. These findings align well with results of a study on cigar smokers’ breath by Bazemore et al. who suggest that due to their structure, pyrazines are trapped in both mucosa and saliva leading to a long-lasting ‘smokers-breath. In comparison, the breath of EC users revealed similar aroma profiles to the ones of NS even immediately after consumption. In doing so, these data suggest that EC use may have personal and social consideration benefits.

description: Internal gravity waves are excited at the interface of convection and radiation zones of a solar-type star by the tidal forcing of a short-period planet. The fate of these waves as they approach the centre of the star depends on their amplitude. We discuss the results of numerical simulations of these waves approaching the centre of a star, and the resulting evolution of the spin of the central regions of the star, and the orbit of the planet. If the waves break, we find efficient tidal dissipation, which is not present if the waves perfectly reflect from the centre. This highlights an important amplitude dependence of the (stellar) tidal quality factor Q', which has implications for the survival of planets on short-period orbits around solar-type stars, with radiative cores.
