title: Time for crops; an exploration of circadian variation in model and crop plant species
Creators: name: Rees, Hannah
Publisher: name: University of Liverpool Repository
Year: 2020

description: Plants with circadian rhythms which are synchronised to their surrounding environments have a well described fitness advantage. Optimising circadian rhythms to fit local conditions has the potential to affect crop productivity, plant health and resource use efficiency. A rising global population and changing climate mean that these factors are becoming increasingly important. Compared to our understanding of other variables affecting plant growth and yields, circadian variation in crop panels is a relatively untapped source of phenotypic variation. Delayed fluorescence (DF) is an intrinsic property of all photosynthetic material, oscillating with a ~24h period controlled by the circadian clock. It has an advantage over other circadian assays in that it requires no prior genetic modification and works well in monocot species which don’t display robust leaf-movement rhythms. In this project, DF imaging was applied as a tool for circadian phenotyping in wheat, Brassica and Arabidopsis. As part of the process, a high throughput, reliable assay was developed specific to detached leaves of either Brassica or wheat. Several factors which contribute to circadian trait variation were examined and demonstrate species- specific differences in optimum DF imaging settings. DF imaging was used to quantify population level circadian variation for two diverse plant panels; 64 cultivars from a Brassica cultivar set and 191 Arabidopsis accessions from across a broad latitudinal range in Sweden. Putative loci associated with this variation were identified using genome wide association mapping. For the Swedish Arabidopsis population, factors contributing to variation in period length in this region were examined, including geography and population sub-structure. This work lends support to the idea that circadian variation exists in wild populations and is likely to provide a competitive advantage in nature. With the robust DF imaging method, circadian phenotypic diversity in domesticated crops can now be examined. It is my hope that this work will facilitate future research into why this diversity has been selected and whether accurate and robust circadian rhythmicity is an important agricultural trait.
title: Understanding household entrepreneurship through intersectionality: A Total Social Organisation of Labour perspective
Creators: name: Baloyo, Mary Joy
Publisher: name: University of Liverpool Repository
Year: 2025

description: Underpinned by gender, work and critical feminist entrepreneurship studies, this study contends that household entrepreneurship is deeply embedded in the social world but is still yet to be fully explored. The interconnection of entrepreneurship and households are central to resource access for venture creation and growth, which contradicts the popularized assumption of dualism and separation of the entrepreneur as a ‘lone hero’. Despite the suggestions given to entrepreneurial households as a ‘neutral unified’ space, however, powerful cultures of structural gendered hierarchy and patriarchy positioned men and women unequally regardless of their significant influence and contributions in both realms. Informed by entrepreneurial household embeddedness perspective this qualitative study explores household entrepreneurship through Acker’s (2006) ‘Intersectional Inequality Regimes’ and Glucksmann’s (2000) ‘Total Social Organisations of Labour’ perspective. This thesis investigates the paradox of household entrepreneurship by asking: How does intersectionality and resource engagement affect the experiences of household entrepreneurship? And vice versa, how does entrepreneurship contribute and affect the experiences of the household? The novel approach of this thesis contributes to entrepreneurship literature by adopting a holistic primacy to entrepreneurial households as the unit of analysis. The empirical example offered here explored these issues by adopting a critical realist view of household entrepreneurship as a multiple case study research. A retroductive process of analysis was undertaken and critical analysis of the household-business nexus exposed how household members accommodated the dilemmas they encountered within household entrepreneurship. Findings from this study yields four assertions: first, it demonstrates that venture creation and growth are simultaneously embedded upon the interconnection of household entrepreneurship nexus and their structural socio-economic conditions. Second, it provides interdisciplinary evidence for the paradox of household entrepreneurship and the enduring dominance of the normative entrepreneurship discourse. Third, it contends that ideologies are embedded within household entrepreneurship mechanisms which (re)produced existing gendered, racialized and classed norms but, at the same time, privileges the ‘visible’ and ‘masculine’ prototypical entrepreneur. Lastly, the study’s holistic perspective fortifies that the context of entrepreneurial household is a gendered hierarchical and an unequal platform, countering entrepreneurship discourse that portrays household entrepreneurship as an ‘egalitarian neutral’ space.

description: The majority of cataclysmic variable (CV) stars contain a stochastic noise component in their light curves, commonly referred to as flickering. This can significantly affect the morphology of CV eclipses and increases the difficulty in obtaining accurate system parameters with reliable errors through eclipse modelling. Here we introduce a new approach to eclipse modelling, which models CV flickering with the help of Gaussian processes (GPs). A parametrized eclipse model – with an additional GP component – is simultaneously fitted to eight eclipses of the dwarf nova ASASSN-14ag and system parameters determined. We obtain a mass ratio q = 0.149 ± 0.016 and inclination i = 83$$_{.}^{\circ}$$4 $$^{+0{^{\circ}_{.}} 9}_{-0{^{\circ}_{.}} 6}$$. The white dwarf and donor masses were found to be Mw = 0.63 ± 0.04 M⊙ and Md = 0.093 $$^{+0.015}_{-0.012}$$ M⊙, respectively. A white dwarf temperature Tw = 14 000 $$^{+2200}_{-2000}$$ K and distance d = 146 $$^{+24}_{-20}$$ pc were determined through multicolour photometry. We find GPs to be an effective way of modelling flickering in CV light curves and plan to use this new eclipse modelling approach going forward.

title: Sex and Relationships Education (SRE) in English schools: A Children's Rights Perspective
Creators: name: Heah, Rachel
Publisher: name: University of Liverpool Repository
Year: 2020

description: This thesis examines the provision of SRE in English schools from a children’s rights perspective. It highlights the importance of SRE for building children’s autonomy and realising their rights to health, education, information, and non-discrimination, among other things. In doing so, it argues that access to SRE is an inherent right of children and young people. It considers the roles of parents and the State in educating children on matters of sexuality, and develops a theoretical for sexuality education that respects children’s rights, without detracting from the parental right to direct their children’s education.

description: An observational constraint on the contribution of double degenerates to Type Ia supernovae requires multiple radial velocity measurements of ideally thousands of white dwarfs. This is because only a small fraction of the double degenerate population is massive enough, with orbital periods short enough, to be considered viable Type Ia progenitors. We show how the radial velocity information available from public surveys such as the Sloan Digital Sky Survey can be used to pre-select targets for variability, leading to a 10-fold reduction in observing time required compared to an unranked or random survey. We carry out Monte Carlo simulations to quantify the detection probability of various types of binaries in the survey and show that this method, even in the most pessimistic case, doubles the survey size of the largest survey to date (the SPY Survey) in less than 15 per cent of the required observing time. Our initial follow-up observations corroborate the method, yielding 15 binaries so far (eight known and seven new), as well as orbital periods for four of the new binaries.

description: Lophosoria quadripinnata (J.F.Gmel.) C.Chr. in Skottsberg, Nat. Hist. Juan Fernandez (Botany) 1: 16. 1920 [1921].
 Range: — Mexico to Panama; Greater Antilles; Colombia to Venezuela and Bolivia (CO, CH, LP, SC); southeastern Brazil; Chile and Argentina.
 Ecology: —Common along roadsides, trails, and ravines, doing best on moist, well-drained soil and in full sun; at 900–3350 m in Bolivia, 0–2000 m in eastern Brazil, Chile and Argentina, and at 100–2700 m in southern Mexico, Mesoamerica, and the Greater Antilles.
 Notes: —This species is recognized by its glaucous or whitish abaxial lamina; no other Bolivian fern of this stature has this character. The laminar layer contains a mixture of triterpenes (Tanaka et al. 1992) that dissolves when the specimens are treated with alcohol. The deposit of this layer may be of some taxonomic value (i.e., deposited only between veins or covering them; epidermal cell structure visible or not) and should be documented in the field if alcohol treatment is necessary. In addition, the specimens show a range of variation in indument characters. The most frequent hair variant has long, soft orange to reddish brown hairs several cm long overlying an appressed white undercoat of catenate, contorted hairs, which are ephemeral when exposed. From this morphology, there are deviations to both extremes. Some plants having only a thick layer of long soft, mostly white hairs (sometimes golden) and no discernable underlying indument. Other plants have all hairs spreading, stiff, and very dark red (at least on petioles); they leave a scabrous surface when abraded on petioles and rachises. Phylogenetic analyses do not resolve according to these morphotypes but rather cluster the samples loosely according to their provenance (Noben et al. 2017).

description: We theoretically investigate the real-time emission spectrum of a two-level atom coupled to an optomechanical cavity (OMC). Using quantum trajectory approach we obtain the single-photon time-dependent spectrum in this hybrid system where the influence of a strong atom-cavity coupling and a strong optomechanical interaction are studied. We find a dressed state picture can explain the spectra by predicting the exact peak locations as well as the relative peak heights. In our analysis we also include the effect of mechanical losses (under weak mechanical damping limit) and single-photon loss through spontaneous emission from the two-level emitter.
Maintaining business process compliance despite changes : a decision support approach based on process adaptations

Publisher: name: Universitäts- und Landesbibliothek Sachsen-Anhalt
Year: 2022
Subjects: subject: 330

description: The term compliance essentially refers to ensuring that business processes, operations and practices conform to an agreed set of rules. Such rules can influence both business processes and components of an information technology (IT) architecture, resulting in relationships between (1) compliance requirements, (2) process elements and (3) IT components. Whenever one element of these three classes is changed, e.g. when outsourcing decisions are made, a relationship analysis becomes necessary in order to identify demanding and violated compliance requirements. Since a manual relationship analysis is a complicated and elaborate task, the paper at hand presents methods to 1) automatically identify potential compliance violations in the context of changes and 2) automatically propose process adaptions for maintaining or re-establishing compliance. The methods are implemented as a software artefact, evaluated as useful in the context of an expert survey and contribute to the support of process adaptation decisions for maintaining compliance following changes.

description: White dwarf stars have been used as flux standards for decades, thanks to their staid simplicity. We have empirically tested their photometric stability by analysing the light curves of 398 high-probability candidates and spectroscopically confirmed white dwarfs observed during the original Kepler mission and later with K2 Campaigns 0–8. We find that the vast majority (>97 per cent) of non-pulsating and apparently isolated white dwarfs are stable to better than 1 per cent in the Kepler bandpass on 1-hr to 10-d time-scales, confirming that these stellar remnants are useful flux standards. From the cases that do exhibit significant variability, we caution that binarity, magnetism and pulsations are three important attributes to rule out when establishing white dwarfs as flux standards, especially those hotter than 30 000 K.

description: The interplay of the tunneling transfer of charges and the emission and absorption of light can be investigated in a setup, where a voltage-biased Josephson junction is connected in series with a microwave cavity. We focus here on the emission processes of photons and analyze the underlying time-dependent statistics using the second-order correlation function $g^{(2)}(τ)$ and the waiting-time distribution $w(τ)$. Both observables highlight the crossover from a coherent light source to a single-photon source. Due to the nonlinearity of the Josephson junction, tunneling Cooper pairs can create a great variety of non-classical states of light even at weak driving. Analytical results for the weak driving as well as the classical regime are complemented by a numerical treatment for the full nonlinear case. We also address the question of possible relations between $g^{(2)}(τ)$ and $w(τ)$ as well as the specific information which is provided by each of them.

title: William Lever: original thinker, accomplished imitator or skilful innovator?
Creators: name: Strickland, Jeannette
Publisher: name: University of Liverpool Repository
Year: 2025

description: William Lever was a late nineteenth century entrepreneurial soap manufacturer who seized opportunities and made the most of them, laying the foundations of a global business that is still in existence today. He was a complex man. To some, he is a hero figure, most notably to his less critical biographers, but he has also been described as a paternalistic despot. Much has been written about Lever, but little has concentrated on his advertising and marketing prowess. With unprecedented access to archival resources not previously afforded to other researchers, this study will reflect upon the concept of entrepreneurial innovation and discuss whether Lever was at the forefront of new developments or whether he was a smart follower who adopted and adapted marketing ideas. It will also analyse some of the myths that have arisen about Lever and how they are perpetuated today. The objectives of this thesis are, therefore, to reflect upon Lever in the context of entrepreneurialism and management, and to discuss how his approach to controlling his business influenced his attitude to advertising and marketing. In doing so, the study will argue that Lever was not as original a thinker as many believe and that his interest in America was a wider reflection of his openness to new ideas and forward thinking, which identify him as an Schumpeterian-style innovator. These ideas formed the basis of his approach to advertising and set him apart from other family-run firms of the time. Furthermore, it will argue that Lever’s skill lay not always in creating new ideas or devising new ways to promote his brands, but in spotting the potential in other people’s endeavours and exploiting them more commercially and that he relied heavily on certain key individuals more than has been acknowledged. In particular, the thesis sheds new light on the use of the new technology of cinematography as a promotional tool.

title: Enzymatic degradation of the cornea to develop an experimental model for keratoconus: Biomechanical and optical characterisation
Creators: name: Kazaili, Ahmed
Publisher: name: University of Liverpool Repository
Year: 2020

description: The cornea is the transparent front part of the eye that covers the iris, pupil, and anterior chamber. It is composed of five layers, in which the stroma is the thickest layer (approximately 90% of corneal thickness) that consists mainly of laminated collagen fibrils associated with proteoglycans. The cornea acts as the eye’s outermost lens that is accounted for approximately two-thirds of the eye's total optical power. Like other lenses, the cornea’s geometrical characteristics, such as the curvature, are important to maintain its functions for clear and stable vision. These geometrical characteristics are highly affected by the biomechanical properties of the cornea. For example, in keratoconus, the cornea is characterised by a progressive and localised thinning in corneal thickness, which is associated with a reduction in stiffness and other biomechanical properties. These alterations happen at the collagenous network, which is mainly responsible for the biomechanical features of the cornea, and are mostly attributed to genetic factors and abnormal enzymatic activity. Histological and biochemical studies suggested the role of amylase and collagenase activities in degradation of collagenous network and progression of keratoconus. However, the role of amylase and collagenase on biomechanical and optical properties have not been investigated. In this study, in vitro enzymatic degradation of porcine corneas was conducted with varying concentrations of α-amylase and collagenase (crude and purified) enzymes for different incubation periods. Several techniques, including atomic force microscopy, nanoindentation and optical coherence tomography, were utilised to assess the effect of the enzymes on biomechanical of corneal tissue at macroscale, microscale and nanoscale levels. Corneal transparency and absorption following enzymatic incubation were also measured using spectrophotometry. The biomechanical techniques that were utilised indicated that amylase and collagenase decrease corneal stiffness and thickness following incubation the corneas with amylase and collagenase. Further reduction in biomechanical properties and thickness of the corneas was found with increased enzymes concentrations and incubation periods. Corneal transparency was increased following incubation with the enzymes. The results suggest depletion of proteoglycans by amylase and digestion of collagen fibrils by collagenase. These results were used to propose an animal biomechanical model for keratoconus.

description: In this paper, we consider the conductivity problem with piecewise‐constant conductivity and Robin‐type boundary condition on the interface of discontinuity. When the quantity of interest is the jump of the conductivity, we perform a local stability estimate for a parameterized non‐monotone family of domains. We give also a quantitative stability result of local optimal solution with respect to a perturbation of the Robin parameter. In order to find an optimal solution, we propose a Kohn–Vogelius‐type cost functional over a class of admissible domains subject to two boundary values problems. The analysis of the stability involves the computation of first‐order and second‐order shape derivative of the proposed cost functional, which is performed rigorously by means of shape‐Lagrangian formulation without using the shape sensitivity of the states variables.
title: Optimisation of CdTe(1-X)SeX and MgXZn(1-X)O layers for CdTe PV devices
Creators: name: Baines, Tom
Publisher: name: University of Liverpool Repository
Year: 2020

description: This thesis presents a study on the optimisation of CdTe(1-X)SeX and MZO layers for CdTe PV applications. The first part of this work focused on the formation of the CdTe(1-X)SeX layers using CdSe layer and its impact on solar cell performance. Initially the incorporation of CdSe layer into conventional CdS/CdTe devices was investigated. This approach was found to be detrimental to all device parameters particularly JSC due to the formation of a CdS(1-X)SeX phase at the CdTe/CdSe/CdS interface. This phase increased the amount of parasitic absorption observed at short wavelength, reduced PV performance, and resulted in excessive void formation at the CdTe device interface. Replacement of CdS with SnO2 as the junction partner layer was found to increase the device photo response at both short and long wavelength due to removal of the CdS and efficient formation of the CdTe(1-X)SeX phase. This resulted in increased device performance of > 13% with notably high JSC values of > 29 mA cm-2. However, removal of CdS did result in a reduced VOC and interface voids were still present. Focus was then placed on alternative oxides to SnO2 which could act as the device window layer but simple binary oxides tested, ZnO, TiO2 and FTO were all found to reduce performance compared to SnO2. The second part of this work therefore investigated MZO layers for CdTe PV. Two approaches were studied, co-sputtering from ZnO and MgO targets or sputtering from a single MZO target. The use of co-sputtered MZO layers was found to be detrimental to performance, due to the high resistivity of the layers and the formation of S-shaped JV curves related to interface charge accumulation. Initially use of single target MZO layers similarly resulted in S-shaped curves and poor performance however, post-growth annealing of the MZO converted the material from amorphous to crystalline and enhanced conductivity of the MZO, removing the charge accumulation. Despite the reduced overall performance compared to SnO2, 11.3% and 13.5% respectively, the MZO devices had an improved VOC demonstrating that with further optimisation of the device junction interface further improvements to performance could be achieved.

description: Danaea (subg. Arthrodanaea) geniculata Raddi, Opusc. Sci. 3: 281. 1819.
 Range: —Greater Antilles; southern Mexico to Bolivia (CO, SC) and southeastern Brazil.
 Ecology: —Fairly common; terrestrial in humid forests, usually along streams or on steep slopes; 200–700 m in Bolivia, to 1300 m elsewhere.
 Notes: —Specimens belonging to this species have traditionally been referred to Danaea elliptica Sm., together with most specimens of subg. Arthrodanaea (Smith et al. 1999, Tuomisto & Moran 2001). However, the type specimen of D. elliptica is a juvenile of D. nodosa (L.) Sm., which renders the former name a synonym of the latter (Christenhusz & Tuomisto 2006). Danaea geniculata is the oldest name that is available to replace D. elliptica for plants in this group, and is used here for the Bolivian material that is not referable to D. arbuscula or any of the other recently described segregate species. However, the type of D. geniculata is from the Atlantic forests of southeastern Brazil, and the species limits in this complex remain to be clarified. The possibility exists that there is an as yet undescribed species in Bolivia.

title: MAKING THE PERSONAL POLITICAL: A Dwelling-Oriented Feminist Approach Towards Wellbeing and Wellbeing Research
Creators: name: Zielke, Julia
Publisher: name: University of Liverpool Repository
Year: 2020

description: Overall, this thesis is concerned about what makes who feel good and function well, by offering an epistemological, methodological and theoretical framework for wellbeing research. To mobilise these ideas, throughout this thesis I build on and contribute to three sets of literatures: i) relational wellbeing is the understanding that being and becoming well is a process of unfolding possibilities with other human and non-human actors and environments across multiple scales of people, places and power (Atkinson et al., 2017), ii) feminist version of dwelling challenges the dichotic assumptions of wellbeing and dwelling (like ill/healthy, outward/inward, alone/together, nature/culture) and argues that we need to engage in the in-between spaces of these spectrums to develop wellbeing possibilities (Todres & Galvin, 2010), and iii) feminist epistemologies and theory are critical about the way that we usually produce knowledge around who is deemed healthy or functional and looks at tools to challenge these power dynamics (Ahmed, 2017). I bring these literatures in conversation with questions pertaining to mental health and wellbeing and their interface with political precarity, austerity, and home (Hall, 2018). I understand home as a nexus or site where a variety of different trajectories and scales (like the intimate, socio-material, economic, historical or political) come together, jump across one another, and are, in the process of researching them, explicitly brought to the fore in the form of personal stories and idiosyncratic experiences. The main body of this thesis comprises three articles: i) a conceptual engagement with wellbeing epistemologies, ii) an empirical study that looks into the experiences of 18 mental health service users through an an arts-based method called Story Houses, and iii) another empirical study that combines Story Houses with interviews of 14 community land trust activists, a type of social housing. My empirical findings together with the theoretical underpinnings put forward an integrative, cross-scalar framework for thinking about wellbeing in a web of wider persisting inequalities, and socio-political and environmental changes.
High field terahertz emission from relativistic laser-driven plasma wakefields

description: We propose a method to generate high field terahertz (THz) radiation with peak strength of GV/cm level in the THz frequency gap range 1-10 THz using a relativistic laser interaction with a gaseous plasma target. Due to the effect of local pump depletion, an initially Gaussian laser pulse undergoes leading edge erosion and eventually evolves to a state with leading edge being step function. Interacting with such a pulse, electrons gain transverse residual momentum and excite net transverse currents modulated by the relativistic plasma frequency. These currents give rise to the low frequency THz emission. We demonstrate this process with one and two dimensional particle-in-cell simulations.

description: Zoonosis is the leading cause of emerging infectious diseases. In a recent article, R. S. Shabman et al. (mSphere 1[1]:e00070-15, 2016, http://dx.doi.org/10.1128/mSphere.00070-15) report the identification of a novel gammaherpesvirus in a cell line derived from the microbat Myotis velifer incautus. This is the first report on a replicating, infectious gammaherpesvirus from bats. The new virus is named bat gammaherpesvirus 8 (BGHV8), also known as Myotis gammaherpesvirus 8, and is able to infect multiple cell lines, including those of human origin. Using next-generation sequencing technology, the authors constructed a full-length annotated genomic map of BGHV8. Phylogenetic analysis of several genes from BGHV8 revealed similarity to several mammalian gammaherpesviruses, including Kaposi’s sarcoma-associated herpesvirus (KSHV).

description: We firstly revisit the importance, naturalness and limitations of the so-called optical metrics for describing the propagation of light rays in the limit of geometric optics. We then exemplify their flexibility and nontriviality in some nonlinear material media and in the context of nonlinear theories of the electromagnetism, both underlain by curved backgrounds, where optical metrics could be flat and impermeable membranes only to photons could be conceived, respectively. Finally, we underline and discuss the relevance and potential applications of our analyses in a broad sense, ranging from material media to compact astrophysical systems.

Magnetic Phenomena in Holographic Superconductivity with Lifshitz Scaling

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We investigate the effects of Lifshitz dynamical critical exponent z on a family of minimal D=4+1 holographic superconducting models, with a particular focus on magnetic phenomena. We see that it is possible to have a consistent Ginzburg-Landau approach to holographic superconductivity in a Lifshitz background. By following this phenomenological approach we are able to compute a wide array of physical quantities. We also calculate the Ginzburg-Landau parameter for different condensates, and conclude that in systems with higher dynamical critical exponent, vortex formation is more strongly unfavored energetically and exhibit a stronger Type I behavior. Finally, following the perturbative approach proposed by Maeda, Natsuume and Okamura, we calculate the critical magnetic field of our models for different values of z.

Extra mass flux in fluid mechanics

Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: The conditions of existence of extra mass flux in single component dissipative non-relativistic fluids are clarified. By considering Galilean invariance we show that if total mass flux is equal to total momentum density, then mass, momentum, angular momentum and booster (center-of-mass) are conserved. However, these conservation laws may be fulfilled also by other means. We show an example of weakly non-local hydrodynamics where the conservation laws are satisfied as well although the total mass flux is different from momentum density.
A Serendipitous Mutation Reveals the Severe Virulence Defect of a Klebsiella pneumoniae fepB Mutant

description: ABSTRACT Klebsiella pneumoniae is considered a significant public health threat because of the emergence of multidrug-resistant strains and the challenge associated with treating life-threatening infections. Capsule, siderophores, and adhesins have been implicated as virulence determinants of K. pneumoniae , yet we lack a clear understanding of how this pathogen causes disease. In a previous screen for virulence genes, we identified a potential new virulence locus and constructed a mutant ( smr ) with this locus deleted. In this study, we characterize the smr mutant and show that this mutation renders K. pneumoniae avirulent in a pneumonia model of infection. The smr mutant was expected to have a deletion of three genes, but subsequent genome sequencing indicated that a much larger deletion had occurred. Further analysis of the deleted region indicated that the virulence defect of the smr mutant could be attributed to the loss of FepB, a periplasmic protein required for import of the siderophore enterobactin. Interestingly, a Δ fepB mutant was more attenuated than a mutant unable to synthesize enterobactin, suggesting that additional processes are affected. As FepB is highly conserved among the members of the family Enterobacteriaceae , therapeutic targeting of FepB may be useful for the treatment of Klebsiella and other bacterial infections. IMPORTANCE In addition to having a reputation as the causative agent of several types of hospital-acquired infections, Klebsiella pneumoniae has gained widespread attention as a pathogen with a propensity for acquiring antibiotic resistance. It is capable of causing a range of infections, including urinary tract infections, pneumonia, and sepsis. Because of the rapid emergence of carbapenem resistance among Klebsiella strains, there is a dire need for a better understanding of virulence mechanisms and identification of new drug targets. Here, we identify the periplasmic transporter FepB as one such potential target.
