Résumé :

Background and aims: The quality of nurse-patient communication has significant effects on patient care outcomes. Therefore, education of communication skills (CSs) to nurses and nursing students can improve patient care outcomes. The aim of this study was to compare the effects of face-to-face education (FTFE) and virtual education (VE) on CSs among nursing students. Methods: This quasi-experimental study was conducted in 2021. Participants were 51 senior nursing students in their internship course in Shahrekord Faculty of Nursing and Midwifery, Shahrekord, Iran. They were recruited to the study through a census and were allocated to FTFE and VE groups through the Random Allocation Software. FTFE was provided in two sessions through the lecture and the question and answer methods, while VE was provided in a single online session through simulated multimedia content. Participants’ CSs were assessed before and ten days after the study intervention through a 50-minute Objective Structured Clinical Examination with five consecutive stations on communication with elderly patient, communication with adolescent patient, communication with aggressive patient, communication with illiterate or non-communicative patient, and communication for consent. Data were analyzed using the SPSS software (v. 23.0) and through the independent sample t, paired-sample t, and chi-square tests and the multivariate analysis of variance (MANOVA). Results: The posttest mean scores of CSs in both groups were significantly greater than their corresponding pretest values (P<0.05). However, there were no significant differences between the groups respecting the pretest and the posttest mean scores of CSs. The pretest mean score of the communication with elderly patient skill and the posttest mean score of the communication with aggressive patient skill had significant relationship with participants’ place of residence and gender, respectively (P<0.05). Conclusion: VE is as effective as FTFE in significantly improving nursing students’ CSs. Therefore, quality VE programs are recommended to fulfill the different educational needs of nursing students.

Résumé :

The FTF (Fusarium Transcription Factor) gene family is composed of two members (FTF1 and FTF2) with high-sequence homology that encode transcription factors involved in the modulation of virulence in the F. oxysporum species complex (FOSC). While FTF1 is a multicopy gene exclusive of highly virulent strains of FOSC and is located in the accessory genome, FTF2 is a single-copy gene, located in the core genome, and well-conserved in all filamentous ascomycete fungi, except yeast. The involvement of FTF1 in the colonization of the vascular system and regulation of the expression of SIX effectors has been stablished. To address the role of FTF2, we generated and characterized mutants defective in FTF2 in a F. oxysporum f. sp. phaseoli weakly virulent strain and analyzed them together with the equivalent mutants formerly obtained in a highly virulent strain. The results obtained highlight a role for FTF2 as a negative regulator of the production of macroconidia and demonstrate that it is required for full virulence and the positive regulation of SIX effectors. In addition, gene expression analyses provided compelling evidence that FTF2 is involved in the regulation of hydrophobins likely required for plant colonization.

Résumé :

The new generation of information technology (IT) promotes the integration of fintech with the real economy. Existing studies emphasize the relationship between fintech and the real economy over the development level of fintech-served real economy (FtRE). To fill up the gap, this paper explores the evaluation of FtRE based on fintech improvement (FtI). Firstly, an evaluation index system (EIS) was established for fintech service efficiency (FtSE), and FtSE was measured through data envelopment analysis (DEA). Then, fuzzy c-means (FCM) clustering was performed to discretize continuous indices. Drawing on matter-element theories, the authors created the classic domain and node domain of FtRE, as well as the evaluation objects of real economy, calculated the correlation between each factor affecting development level and evaluated development level, and computed the weight coefficient of each index. Finally, the influence of FtI-based FtRE development was empirically analyzed through experiments.

Résumé :

This article is based on a paper which was developed for the Global Counterterrorism Forum’s Foreign Terrorist Fighters (ftf) Working Group. It takes stock of the current trends and dynamics related to the ftf phenomenon and identifies some of the gaps that still need to be addressed. The distinction between home-grown terrorists and (returning) ftfs is fading, the difference between isil/Da’esh inspired or directed terrorist attacks is becoming more fluid and the nexus between terrorism and crime is more prominent, which clearly indicates that terrorism can manifest itself in many different ways. The involvement of returning ftfs in some terrorist attacks is a stark reminder of the potential threat returning ftfs pose. The data also indicates a demographic change with a more prominent role of female ftfs and children being recruited and used in hostilities or involved in terrorist attacks. The current trends underline the need for a comprehensive, tailored and multidisciplinary approach including the involvement of stakeholders at the local level to adequately address the evolving aspects of the ftf phenomenon. This paper provides a short overview of policy responses which can broadly be grouped into preventive, criminal, administrative and rehabilitative measures. The ftf related responses could have several human rights implications and states are encouraged to develop a comprehensive approach to address the ftf phenomenon in full respect of human rights.

Résumé :

Flame transfer functions (FTF) of laminar premixed flames acoustically forced are analytically investigated and modelled. The study is based on the linearized G-equation, which is used to kinematically track the flame front. In order to incorporate combustion properties, the laminar consumption speed is considered varying depending on the flame front stretch. Once written in dimensionless form, the G-equation reveals that the FTF depends on 3 dimensionless parameters: a Strouhal number (St2) that accounts for the convective time of the flow perturbation along the flame-front, the flame aspect-ratio (Lf/R) and the dimensionless Markstein length, adimensionalized by the injector radius. It is shown that the latter term is responsible for a flame-flow feedback that acts as damper or amplifier of the flame perturbation, respectively for thermodiffusively stable or unstable flames. A LOM FTF is derived both for Conical and V-flames, highlighting the impact of stretch for each configuration. Ultimately the obtained FTFs are compared to previously proposed analytical FTFs from the literature, underlining the importance of stretch at high frequency.

Résumé :

The researcher is interested in researching the phenomenon of Foreign Terrorist Fighters (FTF) more in-depth. Why is Syria became the main objective of these terrorist fighters because the issue of FTF in Syria is still rare to get researched? The study aims to analyze the phenomenon of Foreign Terrorist Fighters why go to Syria and how the Syrian government’s response to this issue. This study uses FTF theory or concept to explain the FTF phenomenon, also defense and security policy to explain what procedure is used by Bashar al-Assad in the handling of FTF issues. What will be discussed in this research is on the implementation of Syria’s defense and security policy in handling the issue of Foreign Terrorist Fighters, as well as how it impacts on Syria’s security itself. The results of this study suggest that the Syrian government has had a positive impact in implementing its policy for Syria’s protection. The most significant is the reduced number of FTFs coming to Syria. The success of recaptured cities controlled by the previous FTF and more territorial supervision tightened.

Résumé :

ABSTRACT Oral actinomycetes produce fructosyltransferase (FTF) enzymes which convert sucrose into polymers of d-fructose, known as levans, and these polymers are thought to contribute to the persistence and virulence of the organisms. A gene encoding FTF was isolated fromActinomyces naeslundii WVU45; the deduced amino acid sequence showed significant similarity to known levansucrases of gram-negative environmental isolates but was less similar to FTFs from gram-positive bacteria. A transcriptional start site was mapped by primer extension 70 bp 5′ from the putative start codon. Promoter fusions to a chloramphenicol acetyltransferase gene were used to confirm that there was a functional promoter driving ftfexpression and to show that sequences located 86 to 218 bp upstream of the transcription initiation site were required for optimalftf expression. Quantitative slot blot analysis against total RNA from cells grown on different sugars or from different growth phases revealed that ftf was constitutively transcribed. Thus, the A. naeslundii FTF is more similar in primary sequence and the regulation of expression to levansucrases of gram-negative bacteria than gram-positive bacteria.

Résumé :

Purpose The purpose of this study is to extend the current understanding of virtual team (VT) workers’ willingness to continue working in VTs and the forces driving their affective reactions to teamwork. Specifically, this paper applies the input-mediator-output-input (IMOI) literature to investigate the influence of workers’ perceptions of their peers’ skills and peers’ interactions on perceptions of the teamwork process and subsequent affective reactions. Design/methodology/approach This paper draws on a sample of 997 virtual and face-to-face (FtF) students embedded in 242 project teams to test the hypotheses using multi-group comparisons in structural equation modeling (SEM). Findings Results support the assertion that team processes are essential in translating team skills and interactions into satisfaction with the team. Further, this paper finds that skills are more influential on teammate satisfaction for FtFs than they are for VTs; and, conversely, that VTs’ interactions are more pivotal regarding teammate satisfaction through VT processes than they are in FtFs. Research limitations/implications The effort contributes to the IMOI literature by showing how teams overcome virtuality to perform effectively and how team-embedded members react differently across VT and FtF contexts. Originality/value These findings are particularly notable given that prior research has suggested VT performance may not be contingent on social bonds within the team. Although this is possibly true for performance, the findings suggest that social interactions are, in fact, crucial to teams’ affective reactions.

Texte intégral

Résumé :

Gluconobacter species are capable of incomplete oxidations which are exploited in food biotechnology. Levans isolated from exopolysaccharide (EPS)-overproducing Gluconobacter species are promising functional compounds for food applications. Fructan production strongly depends on the corresponding fructosyltransferases (Ftfs), which catalyze the formation of these polymers from sucrose. Therefore, we characterized novel Ftfs from three EPS-overproducing food-grade strains, i.e. Gluconobacter sp. TMW 2.767 and Gluconobacter sp. TMW 2.1191 isolated from water kefir, and Gluconobacter cerinus DSM 9533T isolated from cherries. Several PCR techniques, including degenerate gradient temperature PCR, modified and standard inverse PCR, modified site-finding PCR and modified single primer PCR, were used to finally detect complete open reading frames coding for Ftfs. The prospective ftf-gene sequences were heterologously expressed in Escherichia coli Top 10. E. coli transformants harboring one of the three different ftf-genes produced polysaccharides from sucrose in contrast to the E. coli wildtype. Each of the heterologously expressed proteins encoded a levansucrase, catalyzing the formation of b-(2→6)-linked fructose polymers, which corresponded to our previous analyses about the chemical nature of the isolated polymers formed by these Gluconobacter strains. Structurally, these enzymes belong to the glycoside hydrolase 68 family (GH 68), sharing the typical modular topology of levansucrases from gram-negative bacteria. In conclusion, we could identify novel active levansucrases, which can be used for ex situ (enzymatic catalyses) or in situ (fermentation) production of functional fructan polymers by Gluconobacter strains in food and other applications.

Texte intégral

Résumé :

The site-directed mutated fructosyltransferases (Ftfs) of Streptococcus salivarius ATCC 25975, D312E, D312S, D312N and D312K were all active at 37 °C, indicating that Asp-312 present in the ‘sucrose box’ was not the nucleophilic Asp residue responsible for the formation of a covalent fructosyl-enzyme intermediate required for enzyme activity. Analysis of the kinetic constants of the purified mutated forms of the enzyme showed that Asp-312 was most likely an essential amino acid involved in determining acceptor recognition and/or stabilizing a β-turn in the protein. In contrast, when the Asp-397 of the Ftf present in the conserved triplet RDP motif of all 60 bacterial and plant family-32 glycosylhydrolases was mutated to a Ser residue, both sucrose hydrolysis and polymerization ceased. Tryptophan emission spectra confirmed that this mutation did not alter protein structure. Comparison of published data from other site-directed mutated enzymes implicated the Asp residue in the RDP motif as the one that may form a transient covalent fructosyl intermediate during the catalysis of sucrose by the Ftf of S. salivarius.

Texte intégral

Résumé :

Bacterial fructosyltransferase (FTF) enzymes synthesize fructan polymers from sucrose. FTFs catalyse two different reactions, depending on the nature of the acceptor, resulting in: (i) transglycosylation, when the growing fructan chain (polymerization), or mono- and oligosaccharides (oligosaccharide synthesis), are used as the acceptor substrate; (ii) hydrolysis, when water is used as the acceptor. Lactobacillus reuteri 121 levansucrase (Lev) and inulosucrase (Inu) enzymes are closely related at the amino acid sequence level (86 % similarity). Also, the eight amino acid residues known to be involved in catalysis and/or sucrose binding are completely conserved. Nevertheless, these enzymes differ markedly in their reaction and product specificities, i.e. in β(2→6)- versus β(2→1)-glycosidic-bond specificity (resulting in levan and inulin synthesis, respectively), and in the ratio of hydrolysis versus transglycosylation activities [resulting in glucose and fructooligosaccharides (FOSs)/polymer synthesis, respectively]. The authors report a detailed characterization of the transglycosylation reaction products synthesized by the Lb. reuteri 121 Lev and Inu enzymes from sucrose and related oligosaccharide substrates. Lev mainly converted sucrose into a large levan polymer (processive reaction), whereas Inu synthesized mainly a broad range of FOSs of the inulin type (non-processive reaction). Interestingly, the two FTF enzymes were also able to utilize various inulin-type FOSs (1-kestose, 1,1-nystose and 1,1,1-kestopentaose) as substrates, catalysing a disproportionation reaction; to the best of our knowledge, this has not been reported for bacterial FTF enzymes. Based on these data, a model is proposed for the organization of the sugar-binding subsites in the two Lb. reuteri 121 FTF enzymes. This model also explains the catalytic mechanism of the enzymes, and differences in their product specificities.

Résumé :

This article reflects on the proliferation of responses to the so-called phenomenon of “foreign terrorist fighters,” and the profound human rights challenges they give rise to. It considers national, regional and international developments, many spurred by an activist Security Council, through which expanded powers have been assumed and rights restricted by reference to the need to respond to ftf threats. A series of uncomfortable relationships emerge from this analysis. They include for example tensions: between the evolving and still relatively superficial understanding of the nature and source of uncertain threats and contributing factors on the one hand, and the onerous and far-reaching nature of responses directed against them on the other; between the expansive use of coercive measures including criminal law, and basic constraining principles of criminal law upon which its legitimacy and power depends, such as individual culpability, harm principle and remoteness; or between the original purposes of most ftf measures and their impact in practice, on the operation of humanitarian law, on humanitarian workers and human rights defenders, and on the rule of law. Exceptional ftf measures continue to spread their reach and creep into other areas of security and organised crime. The article highlights the need to consider the short and long term impact, on the full range of rights of many, of the array of administrative, criminal and other measures being passed into law and implemented in practice across the globe in the name of responding to the ill-defined phenomenon of “ftfs”.

Résumé :

This study investigates the existence of chaos on the Johannesburg Stock Exchange (JSE) and studies three indices namely the FTSE/JSE All Share, FTSE/JSE Top 40 and FTSE/JSE Small Cap. Building upon the Fractal Market Hypothesis to provide evidence on the behavior of returns time series of the above mentioned indices, the BDS test is applied to test for non-random chaotic dynamics and further applies the rescaled range analysis to ascertain randomness, persistence or mean reversion on the JSE. The BDS test shows that all the indices examined in this study do not exhibit randomness. The FTSE/JSE All Share Index and the FTSE/JSE Top 40 exhibit slight reversion to the mean whereas the FTSE/JSE Small Cap exhibits significant persistence and appears to be less risky relative to the FTSE/JSE All Share and FTSE/JSE Top 40contrary to the assertion that small cap indices are riskier than large cap indices.

Résumé :

ABSTRACT FtsE and FtsX, which are widely conserved homologs of ABC transporters and interact with each other, have important but unknown functions in bacterial cell division. Coimmunoprecipitation of Escherichia coli cell extracts revealed that a functional FLAG-tagged version of FtsE, the putative ATP-binding component, interacts with FtsZ, the bacterial tubulin homolog required to assemble the cytokinetic Z ring and recruit the components of the divisome. This interaction is independent of FtsX, the predicted membrane component of the ABC transporter, which has been shown previously to interact with FtsE. The interaction also occurred independently of FtsA or ZipA, two other E. coli cell division proteins that interact with FtsZ. In addition, FtsZ copurified with FLAG-FtsE. Surprisingly, the conserved C-terminal tail of FtsZ, which interacts with other cell division proteins, such as FtsA and ZipA, was dispensable for interaction with FtsE. In support of a direct interaction with FtsZ, targeting of a green fluorescent protein (GFP)-FtsE fusion to Z rings required FtsZ, but not FtsA. Although GFP-FtsE failed to target Z rings in the absence of ZipA, its localization was restored in the presence of the ftsA* bypass suppressor, indicating that the requirement for ZipA is indirect. Coexpression of FLAG-FtsE and FtsX under certain conditions resulted in efficient formation of minicells, also consistent with an FtsE-FtsZ interaction and with the idea that FtsE and FtsX regulate the activity of the divisome.

Résumé :

ABSTRACT The chaperonin GroE (GroEL and the cochaperonin GroES) is the only chaperone system that is essential for the viability of Escherichia coli. It is known that GroE-depleted cells exhibit a filamentous morphology, suggesting that GroE is required for the folding of proteins involved in cell division. Although previous studies, including proteome-wide analyses of GroE substrates, have suggested several targets of GroE in cell division, there is no direct in vivo evidence to identify which substrates exhibit obligate dependence on GroE for folding. Among the candidate substrates, we found that prior excess production of FtsE, a protein engaged in cell division, completely suppressed the filamentation of GroE-depleted E. coli. The GroE depletion led to a drastic decrease in FtsE, and the cells exhibited a known phenotype associated with impaired FtsE function. In the GroE-depleted filamentous cells, the localizations of FtsA and ZipA, both of which assemble with the FtsZ septal ring before FtsE, were normal, whereas FtsX, the interaction partner of FtsE, and FtsQ, which is recruited after FtsE, did not localize to the ring, suggesting that the decrease in FtsE is a cause of the filamentous morphology. Finally, a reconstituted cell-free translation system revealed that the folding of newly translated FtsE was stringently dependent on GroEL/GroES. Based on these findings, we concluded that FtsE is a target substrate of the GroE system in E. coli cell division.

Résumé :

Abstract Since 2011, the conflict in Syria and Iraq has seen unprecedented numbers of Westerners travelling to the region to support jihadist terror organisations, so-called Foreign Terrorist Fighters (‘FTFs’). However, since 2015, with Islamic State’s financial and territorial losses, the numbers of Western FTFs are dwindling and many are returning to their countries of origin. As a consequence, numerous countries are grappling with how to best manage potential security threats arising from returning FTFs. This article critically analyses legal and criminal justice strategies to address this phenomenon implemented in three Western countries from which a significant number of FTFs originate: Germany, the United Kingdom and Australia. It focuses on prosecution, prevention of re-entry and rehabilitation of returning FTFs. It suggests that a holistic approach focusing on punitive but also on de-radicalising and reintegrating measures is best suited to address the security risks FTFs pose long term.

Résumé :

ABSTRACT The serine cycle methylotroph Methylobacterium extorquens AM1 contains two pterin-dependent pathways for C1 transfers, the tetrahydrofolate (H4F) pathway and the tetrahydromethanopterin (H4MPT) pathway, and both are required for growth on C1 compounds. With the exception of formate-tetrahydrofolate ligase (FtfL, alternatively termed formyl-H4F synthetase), all of the genes encoding the enzymes comprising these two pathways have been identified, and the corresponding gene products have been purified and characterized. We present here the purification and characterization of FtfL from M. extorquens AM1 and the confirmation that this enzyme is encoded by an ftfL homolog identified previously through transposon mutagenesis. Phenotypic analyses of the ftfL mutant strain demonstrated that FtfL activity is required for growth on C1 compounds. Unlike mutants defective for the H4MPT pathway, the ftfL mutant strain does not exhibit phenotypes indicative of defective formaldehyde oxidation. Furthermore, the ftfL mutant strain remained competent for wild-type conversion of [14C]methanol to [14C]CO2. Collectively, these data confirm our previous presumptions that the H4F pathway is not the key formaldehyde oxidation pathway in M. extorquens AM1. Rather, our data suggest an alternative model for the role of the H4F pathway in this organism in which it functions to convert formate to methylene H4F for assimilatory metabolism.

Résumé :

This paper explores the effect of the return and volatility spillover between the Standard and Poor’s 500 index and FTSE All-Share index using the AG-DCC_ Dynamic Conditional Correlation model over the sample period from April 1995 to April 2019. It demonstrates that the Standard and Poor’s 500 return and volatility are crucial in forecasting the market’s future dynamics of the FTSE All Shares where it finds a significant spillover effect for both return and volatility from the Standard and Poor’s 500 to FTSE All Shares, while weak evidence has been found in the opposite direction, that is, an insignificant spillover effect for both return and volatility from FTSE All Shares to the Standard and Poor’s 500. In addition, the paper also finds high Dynamic Conditional Correlation (DCC) between both the Standard and Poor’s 500 and FTSE All Shares. Therefore, it finds asymmetric correlation and transmission mechanisms between the Standard and Poor’s 500 and FTSE All Shares, which means there is an asymmetric interconnectedness between two markets, so allocating assets between two markets will not benefit investor portfolios as investing in high-yielding shares do.

Texte intégral

Résumé :

Data centers undertake transfer, calculation, and store of important information, whose suitable thermal environment is necessary for the safe and reliable operation of information technology (IT) equipment. However, in case of the emergency failure or power outage of the air-conditioning system, the inappropriate thermal environment cannot keep the proper operation of IT equipment. Therefore, a novel cooling system is proposed to maintain the thermal environment of server rooms, in which the liquid nitrogen as refrigerant flows into the spiral finned tube heat exchanger (FTHE) by phase changing to take away indoor heat. The effect of horizontal spacings and heights of the FTHE on the thermal environment are investigated numerically. The results display that the indoor air temperature is divided by FTHE. When the height of FTHE is 2.6~2.9m, the higher the FTHE, the more uniform the indoor temperature distribution. When the FTHE is higher than 3.2 m, the maximum temperature of the heat source is more than 62.6°C, exceeding the temperature tolerance limit. In addition, if space permits, the dislocation layout and the fixed layout can be selected, which perform well in both temperature uniformity and heat source cooling. This investigation provides support for the arrangement of the novel cooling system.

Résumé :

Over the last decades several studies have searched for improved Fin and Tube Heat Exchanger (FTHE) designs capable of providing the best thermo-hydraulic performance. The present study aims at quantifying and comparing the thermo-hydraulic performance of different FTHE configurations. Six different designs were analyzed. The first FTHE consisted of an in-line circular tube arrangement and the last one was a FTHE with staggered oval tube with two pairs of Delta Winglet Vortex Generators (DWVG) in common flow up–common flow down (CFU-CFD) configuration. The best performance was obtained using DWVG in CFU-CFD orientation. This configuration enabled a 90% increase of the thermal performance factor when compared with the first case, using only two pairs of vortex generator´s per tube.

Résumé :

Since it had established a caliphate in 2014, Islamic State of Iraq and Syria (ISIS) continued to threaten the international peace and security by attacking and killing civilians. ISIS foreign terrorist fighters (FTFs) are ISIS members who have combat functions. Altough it is a serious crime, terrorism has not yet been recognized as a stand-alone core international crimes according to customary international law. The fact that ISIS is referred to as a terrorist groups, not a state-entity, has also raised a question of whether ISIS FTFs can only be prosecuted for committing terrorism related offences. This paper argues that terrorism acts by ISIS FTFs can fit the element of the existing core international crimes such as crimes against humanity, war crimes and genocide To this end, this paper elaborates the most common offences committed by ISIS FTFs and analyses element of each of core international crimes. This paper concludes that ISIS FTFs should be held liable for those core international crimes and prosecuted before national and international criminal court accordingly.

Texte intégral

Résumé :

The faults characteristics of the lines in AC microgrid are weakened due to the fault resistance, which may refuse protection action. To solve the problems caused by different types of the faults through fault resistance (FTFR, the faults where the fault point resistance is greater than zero) in AC microgrid, a novel FTFR protection scheme based on the active power of 0-frame component or d-frame component consumed by fault resistance is proposed in this paper as the backup protection of FTFR. This proposed protection scheme utilizes the active power of 0-frame component or d-frame component consumed by fault resistance to identify internal FTFR and external faults. It performs well in grid-connected mode and islanded mode by adopting self-adaptive threshold and is not affected by the factors such as the fault position and the fault resistance value. The theoretical analysis and various simulations show that this protection scheme can identify and isolate different types of internal FTFR in AC microgrid with high reliability and high sensitivity.

Résumé :

ABSTRACT The ftsE(Ts) mutation of Escherichia colicauses defects in cell division and cell growth. We expressed alkaline phosphatase (PhoA) fusion proteins of KdpA, Kup, and TrkH, all of which proved functional in vivo as K+ ion pumps, in the mutant cells. During growth at 41°C, these proteins were progressively lost from the membrane fraction. The reduction in the abundance of these proteins inversely correlated with cell growth, but the preformed proteins in the membrane were stable at 41°C, indicating that the molecules synthesized at the permissive temperature were diluted in a growth-dependent manner at a high temperature. Pulse-chase experiments showed that KdpA-PhoA was synthesized, but the synthesized protein did not translocate into the membrane of the ftsE(Ts) cells at 41°C and degraded very rapidly. The loss of KdpA-PhoA from the membrane fractions of ftsE(Ts) cells was suppressed by a multicopy plasmid carrying the ftsE + gene. While cell growth stopped when the abundance of these proteins decreased 15-fold, the addition of a high concentration of K+ ions specifically alleviated the growth defect of ftsE(Ts) cells but not cell division, and the cells elongated more than 100-fold. We conclude that one of the causes of growth cessation in the ftsE(Ts) mutants is a defect in the translocation of K+-pump proteins into the cytoplasmic membrane.

Texte intégral

Résumé :

The alpha1-fetoprotein (AFP) gene is located between the albumin and alpha-albumin genes and is activated by transcription factor FTF (fetoprotein transcription factor), presumed to transduce early developmental signals to the albumin gene cluster. We have identified FTF as an orphan nuclear receptor of the Drosophila FTZ-F1 family. FTF recognizes the DNA sequence 5'-TCAAGGTCA-3', the canonical recognition motif for FTZ-F1 receptors. cDNA sequence homologies indicate that rat FTF is the ortholog of mouse LRH-1 and Xenopus xFF1rA. Rodent FTF is encoded by a single-copy gene, related to the gene encoding steroidogenic factor 1 (SF-1). The 5.2-kb FTF transcript is translated from several in-frame initiator codons into FTF isoforms (54 to 64 kDa) which appear to bind DNA as monomers, with no need for a specific ligand, similar KdS (approximately equal 3 x 10(-10) M), and similar transcriptional effects. FTF activates the AFP promoter without the use of an amino-terminal activation domain; carboxy-terminus-truncated FTF exerts strong dominant negative effects. In the AFP promoter, FTF recruits an accessory trans-activator which imparts glucocorticoid reactivity upon the AFP gene. FTF binding sites are found in the promoters of other liver-expressed genes, some encoding liver transcription factors; FTF, liver alpha1-antitrypsin promoter factor LFB2, and HNF-3beta promoter factor UF2-H3beta are probably the same factor. FTF is also abundantly expressed in the pancreas and may exert differentiation functions in endodermal sublineages, similar to SF-1 in steroidogenic tissues. HepG2 hepatoma cells seem to express a mutated form of FTF.

Résumé :

BackgroundGovernment leaders have called for increased use of video-consulting (VC) in clinical practice. Although provided by the private sector, it is rarely used in NHS primary care. It is unclear how VC differs from telephone (TC) or face-to-face consulting (FTFC), or how useful clinicians and patients find it.AimTo assess the feasibility and acceptability to patients and clinicians of running a VC service in general practice and to explore differences in duration and content compared with FTFC and TC.MethodVC equipment was installed in six GP practices and 13 clinicians were asked to identify patients who required follow-up consultations and who had access to a smart-device or laptop. They were offered the choice of a VC, TC, or FTFC. Consultations were audiorecorded and content analysed using the RIAS system. Patient and clinician views were obtained by questionnaires and interviews.ResultsOne hundred and forty-seven patients were recruited (FTFC = 51, TC = 51, VC = 45). VC users were generally younger. VCs and TCs were shorter (mean VC 5.9, TC 5.6, FTFCs 9.6 minutes), addressed fewer problems (mean VC 1.5, TC 1.7, FTFC 2.0) and had less information exchange than FTFCs. Technical problems were common, but VCs offered significant advantages over TC in terms of non-verbal communication. VC was considered particularly useful to working and housebound people and for those with mental health problems.ConclusionVC has distinct advantages over TC. When integrated into current systems VC will provide an alternative to FTFC. Where formal physical examination is not required (discussing test results, medication changes and mental health) it offers considerable time savings to patients.

Résumé :

This study proposes a new approach to examining executive remuneration and manager characteristics disaggregated by market index peer clusters and analyses personal attributes that differentiate managers across companies of different market caps (proxied my market indices such as FTSE 100, FTSE 250, FTSE SmallCap, and AIM). Our sample is composed of biographical data on 790 executive directors from 125 UK financial firms covering a 2004-2016 time period. The results show that network and education are the most important factors for career progression. On average, FTSE 100 executive directors are three times better connected and two times better educated than FTSE SmallCap and AIM board members. The larger the firm, the more diverse the board with more international (non-British) and female directors (even though male executives mostly dominate). The higher position is associated with greater age, while new executives tend to be younger and better connected. We highlight a change in the new managers’ skill-set after the financial crisis which may presumably be explained by risk aversion. New directors appointed after 2008 are, on average, older and better educated. Even though after the crisis we document that all the boardrooms, except FTSE SmallCap, appear to have become more gender diverse, the female presence in the boards is scarce and the highest number of women was mainly employed during the financial crisis. After 2008, British boards have become less nationality diverse. Thus, for the purpose of maintaining companies’ competitive advantage in increasingly diverse markets, it requires further attention from policy regulators.

Résumé :

Small-scale affordable extruders create new opportunities for small enterprise food processors to manufacture nutritionally enhanced products. Still, consumer interest in these products needs to be assessed first. Affective tests with 296 consumers in Dakar, Senegal, evaluated five pearl millet flours: (a) conventional, compared to four instant-porridge flour products; (b) sifted; (c) wholegrain; (d) sifted with premix; (e) wholegrain with micronutrient premix and food-to-food fortified (FtFF). Willingness-to-pay (WTP) was elicited through experimental auctions under two treatments: firstly without information, then with information. Consumers liked FtFF (taste, aroma, appearance) but were indifferent to instant. They did not appreciate wholegrain flour (appearance) or premix (appearance, aroma and taste). Without information, consumers showed no differences in WTP. With information, consumers paid premiums for FtFF (27-30%) (both treatments), and premix (17%), instant (9%), and wholegrain (-10%) (one treatment). Costs of instant, wholegrain and premix products were lower than consumers’ WTP, indicating potential profits, but not those of FtFF. There is a market for instant cereals in Senegal. Consumers require product information in order to compromise on some attributes to benefit from instant, fortified and wholegrain pearl millet products. Manufacture would be cost-effective, but FtFF costs need to be reduced.

Texte intégral

Résumé :

Fractional tissue oxygen extraction (FTOE) by means of cerebral near-infrared spectroscopy (NIRS) provides information about oxygen uptake in the brain. Experimental animal data suggest that sedative agents decrease cerebral oxygen demand. The aim of the present study was to investigate the association between the cerebral FTOE and the use of pre and intraoperative sedative agents in infants aged 1–90 days. Cerebral NIRS was continuously applied during open major non-cardiac surgery in 46 infants. The main outcomes were the mean intraoperative FTOE and the percentage (%) of time of intraoperative hyperoxiaFTOE relative to the total duration of anesthesia. HyperoxiaFTOE was defined as FTOE ≤ 0.1. Cumulative doses of sedative agents (benzodiazepines and morphine), given up to 24 h preoperatively, correlated with the mean intraoperative FTOE (Spearman’s rho = −0.298, p = 0.0440) and were predictive for the % of time of intraoperative hyperoxiaFTOE (β (95% CI) 47.12 (7.32; 86.92)) when adjusted for the patients’ age, type of surgery, preoperative hemoglobin, intraoperative sevoflurane and fentanyl dose, mean intraoperative arterial blood pressure, and end-tidal CO2 by multivariate 0.75 quantile regression. There was no association with 0.5 quantile regression. We observed the suggestive positive association of decreased fractional cerebral tissue oxygen extraction and the use of sedative agents in neonates and infants undergoing surgery.

Résumé :

Abstract In order to realize the mass production of the large-area flexible transparent film heater (FTFH) at low-cost, this paper presents a novel method which can achieve the direct fabrication of the large-area FTFH with Ag-grid by using an electric-field-driven jet deposition micro-scale 3D printing. The effects of the line width and the pitch of the printed Ag-grids on the optical transmittance and the sheet resistance are revealed. A typical FTFH with area of 80 mm × 60 mm, optical transmittance of 91.5% and sheet resistance of 4.7 Ω sq−1 is fabricated by the nano-silver paste with a high silver content (80 wt.%) and high viscosity (up to 20 000 mPa · s). Temperature-time response profiles and heating temperature distribution show that the heating performance of the FTFH has good thermal and mechanical properties. Furthermore, the adhesive force grade between the Ag-grid and the PET substrate measured to be 4B by 3M scotch tape. Therefore, the FTFH fabricated here is expected to be widely used in industry, such as window defroster of vehicles and display or touch screens owing to its striking characteristics of large area and low cost fabrication.

Résumé :

This study analyses whether the board characteristics (diversity attributes, competitive capital, time commitment) of companies listed on the Financial Times Stock Exchange FTSE100 exhibit a different performance compared to those associated with conventional benchmark indices (FTSE250, FTSE SMALLCAP (small capitalisation), FTSE Fledgling, and FTSE All-Shar). Using multivariate analysis and unbalanced panel data over the period 2000−2014, we provide novel evidence on how the UK stock market indices react to diversity in board characteristics. Our findings reveal that different aspects of board characteristics are significantly correlated with the performance of FTSE indices. This study further confirms that boards with high levels of diversity maintain better and more effective levels of governance, in particular for companies listed on FTSE100 and FTSE250. Interestingly, we report that the competitive capital and busyness associated with boards of companies listed on FTSE100 have professional, well-educated, and socially connected boards, and show a clear pattern whereby boards become significantly less competitive as firm size decreases.

Résumé :

The paper examines the relative performance of Stochastic Volatility (SV) and Generalised Autoregressive Conditional Heteroscedasticity (GARCH) (1,1) models fitted to ten years of daily data for FTSE. As a benchmark, we used the realized volatility (RV) of FTSE sampled at 5 min intervals taken from the Oxford Man Realised Library. Both models demonstrated comparable performance and were correlated to a similar extent with RV estimates when measured by ordinary least squares (OLS). However, a crude variant of Corsi’s (2009) Heterogeneous Autoregressive (HAR) model, applied to squared demeaned daily returns on FTSE, appeared to predict the daily RV of FTSE better than either of the two models. Quantile regressions suggest that all three methods capture tail behaviour similarly and adequately. This leads to the question of whether we need either of the two standard volatility models if the simple expedient of using lagged squared demeaned daily returns provides a better RV predictor, at least in the context of the sample.

Résumé :

Chiral anomalies for Abelian and non-Abelian quantum field theories at finite temperature and density (FTFD) are analyzed in detail in both imaginary and real time (IT and RT) formalisms. IT and RT triangle diagrams and IT functional methods (à la Fujikawa) are used at FTFD. The vector anomaly (the one regarding the lepton and baryon numbers) in the Weinberg–Salam theory, for an arbitrary number of fermion families, is also treated using IT functional methods at FTFD. In all cases, the expressions for the FTFD anomalies (as functions of the corresponding quantities) turn out to be identical to those at zero temperature and density, thereby extending previous results by various authors for the finite temperature and zero density case. Moreover, the independence of anomalies from temperature and density is shown to be consistent, at least in the Abelian case, with the analytic continuation from the IT formulation to the RT one.
