description: Operation of membrane systems for water treatment can be seriously hampered by biofouling. A better characterization of biofilms in membrane systems and their impact on membrane performance may help to develop effective biofouling control strategies. The objective of this study was to determine the occurrence, extent and timescale of biofilm compaction and relaxation (decompaction), caused by permeate flux variations. The impact of permeate flux changes on biofilm thickness, structure and stiffness was investigated in situ and non-destructively with optical coherence tomography using membrane fouling monitors operated at a constant crossflow velocity of 0.1 m s−1 with permeate production. The permeate flux was varied sequentially from 20 to 60 and back to 20 L m−2 h−1. The study showed that the average biofilm thickness on the membrane decreased after elevating the permeate flux from 20 to 60 L m−2 h−1 while the biofilm thickness increased again after restoring the original flux of 20 L m−2 h−1, indicating the occurrence of biofilm compaction and relaxation. Within a few seconds after the flux change, the biofilm thickness was changed and stabilized, biofilm compaction occurred faster than the relaxation after restoring the original permeate flux. The initial biofilm parameters were not fully reinstated: the biofilm thickness was reduced by 21%, biofilm stiffness had increased and the hydraulic biofilm resistance was elevated by 16%. Biofilm thickness was related to the hydraulic biofilm resistance. Membrane performance losses are related to the biofilm thickness, density and morphology, which are influenced by (variations in) hydraulic conditions. A (temporarily) permeate flux increase caused biofilm compaction, together with membrane performance losses. The impact of biofilms on membrane performance can be influenced (increased and reduced) by operational parameters. The article shows that a (temporary) pressure increase leads to more compact biofilms with a higher hydraulic resistance.

description: An excellent candidate for a young elliptical, or 'protoelliptical' galaxy is NGC 1700. Here we present new B-, V- and I-band imaging using the Keck telescope, and reanalyse existing V- and I-band images from the Hubble Space Telescope. After subtracting a model of the galaxy from the Keck images, NGC 1700 reveals two symmetric tidal tail-like structures. If this interpretation is correct, it suggests a past merger event involving two spiral galaxies. These tails are largely responsible for the `boxiness' of the galaxy isophotes observed at a radius of ~13kpc. We also show that the B-I colour distribution of the globular cluster system is bimodal. The mean colour of the blue population is consistent with that of old Galactic globular clusters. Relative to this old, metal-poor population, we find that the red population is younger and more metal-rich. This young population has an age and metallicity similar to that inferred for the central stars, suggesting that both populations are associated with an episode of star formation triggered by the merger that may have formed the galaxy. We find that, although they have large errors, the majority of the age estimates of NGC 1700 are reasonably consistent and we adopt a 'best estimate' for the age of 3.0+/-1.0Gyr. This relatively low age places NGC 1700 within the age range where there is a notable lack of obvious candidates for protoellipticals. The total globular cluster specific frequency is rather low for a typical elliptical, even after taking into account the fading of the galaxy over the next 10Gyr. We speculate that NGC 1700 will eventually form a relatively 'globular cluster poor' elliptical galaxy.

description: Oncogenic mutation of KRAS (Kirsten rat sarcoma viral oncogene homolog) in colorectal cancer (CRC) confers resistance to both chemotherapy and EGFR (epidermal growth factor receptor)-targeted therapy. We uncovered that KRAS mutant (KRASmut) CRC is uniquely sensitive to treatment with recombinant LGALS9/Galectin-9 (rLGALS9), a recently established regulator of epithelial polarity. Upon treatment of CRC cells, rLGALS9 rapidly internalizes via early- and late-endosomes and accumulates in the lysosomal compartment. Treatment with rLGALS9 is accompanied by induction of frustrated autophagy in KRASmut CRC, but not in CRC with BRAF (B-Raf proto-oncogene, serine/threonine kinase) mutations (BRAFmut). In KRASmut CRC, rLGALS9 acts as a lysosomal inhibitor that inhibits autophagosome-lysosome fusion, leading to autophagosome accumulation, excessive lysosomal swelling and cell death. This antitumor activity of rLGALS9 directly correlates with elevated basal autophagic flux in KRASmut cancer cells. Thus, rLGALS9 has potent antitumor activity toward refractory KRASmut CRC cells that may be exploitable for therapeutic use.

description: AIMS: To determine some of the risk factors for cows not observed in oestrus within 35–42 days of an unsuccessful artificial insemination (AI; phantom cows), and the reproductive outcomes and effect of treatment of phantom cows.MATERIALS AND METHODS: Over 2 years, in dairy herds from the Waikato (n=10) and Canterbury (n=4) regions of New Zealand, pregnancy diagnosis was carried out 35–42 days after AI on cows that had been inseminated in the first 3 weeks after the start of mating (PSM) but had not been seen returning to oestrus. Risk factors for phantom cows were analysed using a generalised linear mixed effect model.In Year 1, all phantom cows were left untreated. In Year 2, phantom cows were categorised as having a corpus luteum (CL) (CL+ n=120), or having ovarian follicles ≥10 (n=101) or <10 (n=40) mm in diameter. Cows with a CL were treated with cloprostenol or untreated and placed with bulls. Cows with no CL received intravaginal progesterone (P4) for 7 days, with injection of gonadotrophin-releasing hormone (GnRH) on Days 0 and 9, and cloprostenol on Day 7 followed by AI. Pregnancy diagnosis of all cows took place 100–120 days after PSM and interval to conception and final pregnancy rate determined.RESULTS: Overall, of cows inseminated in the first 3 weeks after PSM that did not return to oestrus, 610/6,734 (9.1%) were phantom cows. From the final multivariable analysis, treatment for anoestrus, BCS ≤4.0 at mating, being 2 or >6 years of age, and pure-bred, and decreasing interval between calving and mating, until 98 days post calving, were associated with increased odds of being a phantom cow. Compared to all other groups of cows, phantom cows had a longer interval to conception (p<0.001) and a lower final pregnancy rate (p<0.001).Treatment of CL+ cows or cows with follicles ≥10 mm did not affect reproductive outcomes (p>0.3). For cows with follicles <10 mm treatment decreased the final percentage not pregnant (3/27; 11%; p=0.01) and interval to conception (21 days; p=0.02) compared with controls (7/13; 54% and 37 days, respectively).CONCLUSIONS AND CLINICAL RELEVANCE: Risk factors for phantom cows were identified that could be manipulated to reduce the number of phantom cows in a herd, in particular increasing BCS. Treatment of the majority of phantom cows did not improve reproductive performance.

description: With a views to observe the effect of prevailing air temperature at irrigated late sowing (ILS) conditions on phenological traits of advanced wheat genotypes and to identify heat tolerant genotypes, the trial was carried out in the research field of Wheat Research Centre, Bangladesh Agricultural Research institute (BARI), Nashipur, Dinajpur in the season of 2011-12. The treatments were four dates of sowing viz. 30 Nov (D1), 15 Dec (D2), 30 Dec (D3), 14 Jan (D4) and four genotypes viz. BARI Gom 26 (V1), BAW 1051 (V2), BAW 1120 (V3), BAW 1141(V4) . The genotypes V2, V3, and V4 were taken as tested genotypes and V1 as check. The design was split-plot with three replications. In ILS conditions, the genotypes phased high temperature stress that significantly reduced the duration of booting, heading, anthesis and physiological maturity stages of all genotypes compared as irrigated timely sowing (ILS, D1) condition since those faced 21 to 25.8oC average mean temperature during booting to physiological maturity stages from 19 February to 09 April, 2012 (10 days interval minimum and maximum temperature was averaged). All genotypes sown on 30 Nov. and 15 Dec. produced yield more than 4 t ha-1 but produced less than 4 t ha-1 in other ILS conditions except BAW 1141 seeded on 30 December. Considering overall performance, BAW 1120 and BAW 1141 may be cultivated up to 15 December and 30 December to get yield 3.34 t ha-1 and 4.15 t ha-1, respectively as heat tolerant genotypes.

description: A novel fluorogenic signalling probe (E)-3-(4-methoxyphenyl)-4-[(4-nitrobenzylidene)amino]-1H-1,2,4-triazole-5(4H)-thione (6) for the carbonate and bicarbonate ions has been developed through microwave assisted Schiff base formation reaction. The anion recognition occurs through hydrogen bonding assessed by 1H NMR titration experiments. The photophysical results of probe 6 corroborates its applicability as an optical sensing platform for carbonate as well as bicarbonate ions in mixed aqueous organic media depending on pH of reaction solution. The fluorescence emission signal enhancement at 424 nm and considerable shift in the signal position as well as molar absorptivity to the probe absorption bands upon CO32− and HCO3− addition suggest the affinity of probe 6 towards these ions in comparison to a variety of competitive ions in aqueous/ethanol (7:3, v/v) at neutral pH and ambient temperature. From the fluorescence titration experiment, the limit of detection was calculated to be 1.91 μM.

description: Information and Communication Technologies (ICTs) are increasingly accessible and affordable worldwide. This trend has raised high expectations regarding their potential to revolutionize smallholder agriculture by providing farmers with access to information, markets and financial services. Despite the increasing rates of mobile usage and investments in the development of these techno- logies, uptake of agriculture-specific ICT solutions has been low and few have scaled up to achieve profitability and significant quantifiable impacts. But the technological dream is still possible. ICTs can conceivably lead to large productivity improvements. Achieving their widespread use among smallholder farmers will require affordable solutions that are adjusted to the capacities of the users and their devices. At the same time, investments in more sophisticated ICT solutions higher up in the value chain can also benefit smallholder farmers.

description: La définition de la transformation digitale est le processus grâce auquel les entreprises incorporent les technologies digitales dans chaque aspect de leurs activités. Cette définition simpliste cache cependant une signification plus large. La technologie a radicalement changé presque tous les aspects de la vie des gens, y compris les secteurs économiques. En raison de l’influence rapide de la technologie, de l’évolution des comportements et des attentes des consommateurs, il est difficile pour ces derniers de suivre le rythme, les secteurs de la finance ne font pas exception. Ainsi, il est frappant de constater à quel point le secteur de la sécurité et de la finance, qui est profondément ancré dans les anciennes traditions de la bureaucratie, doit s’adapter à ce nouveau monde en constante évolution. Cette tentative analyse les impacts de la transformation digitale sur les banques et examine à la fois ses avantages et les enjeux actuels. La transformation digitale constitue un moteur essentiel de changement dans le secteur bancaire. Elle enrichit l'expérience client, améliore l'efficacité opérationnelle, renforce la sécurité et favorise l'innovation. Toutefois, elle introduit également des défis en matière de sécurité et de gestion des risques. Les banques doivent adopter une approche proactive et agile pour s'adapter à cet environnement en constante évolution, en exploitant les technologies numériques pour proposer des services plus efficaces, sécurisés et personnalisés. En somme, la transformation digitale offre aux banques une opportunité unique de réinventer leurs modèles économiques et de mieux répondre aux besoins de leurs clients dans un monde de plus en plus connecté.

Cette étude vise à offrir une compréhension approfondie des avantages et des inconvénients de la transformation numérique dans le secteur bancaire, en examinant également son impact sur la satisfaction et l'expérience des clients. Elle évalue par ailleurs les avantages et les inconvénients de la digitalisation d'un point de vue réglementaire et met en lumière l'importance de la cybersécurité dans le contexte du secteur bancaire numérique.

description: Transforming rural areas and increasing the productivity of smallholder farms are indispensable to meet the goal of overcoming hunger and malnutrition. After years of improvements, hunger levels rose again in 2016. Of the 815 million undernourished people, 20% are small children. ‘Hidden hunger’ also remains a serious concern; micronutrient deficiencies affect around 2 billion people and pose significant social, political, and public health challenges. As hunger and malnutrition grow increasingly more complex, it must be countered by sophisticate policies and innovative thinking. In this regard, food and agricultural innovations play essential roles to overcome hunger sustainably and effectively.

description: We describe a scheme for the formation of globular cluster systems in early-type galaxies using a semi-analytic model of galaxy formation. Operating within a lambda CDM cosmology, we assume that metal-poor globular clusters are formed at high-redshift in pre-galactic fragments, and that the subsequent gas-rich merging of these fragments leads to the formation of metal-rich clusters. We compare our results with contemporary data, and look at the particular case of the globular cluster and stellar metallicity distribution function of the nearby elliptical Centaurus A.

High-resolution single-pulse studies of the Vela pulsar

description: We present high-resolution multi-frequency single-pulse observations of the Vela pulsar, PSR B0833 - 45, aimed at studying micro-structure, phase-resolved intensity fluctuations and energy distributions at 1.41 and 2.30 GHz. We find micro-structure in about 80 per cent of all pulses independent of observing frequency. The width of a micro-pulse seems to depend on its peak flux density, whilst quasi-periodicities observed in micro-pulses remain constant. The width of the micro-pulses may decrease with increasing frequency, but confirmation is needed at higher frequencies. The fraction of pulses showing quasi-periodic micro-pulses may become smaller at higher frequencies. We show that the micro-pulse width in pulsars has a period dependence which suggests a model of sweeping micro-beams as the origin of the micro-pulses. Like individual pulses, the micro-pulses of Vela are highly elliptically polarized. There is a strong correlation between Stokes parameters V and I in the micro-structure. We do not observe any micro-pulses where the handedness of the circular intensity changes within a micro-pulse, although flips within a pulse are not uncommon. We show that the V/I distribution is Gaussian with a narrow width and that this width appears to be constant as a function of pulse phase. The phase-resolved intensity distributions of I are best fitted with log-normal statistics. Extra emission components, i.e. ‘bump’ and ‘giant micro-pulses’, discovered by Johnston et al. at 0.6 and 1.4 GHz are also present at the higher frequency of 2.3 GHz. The bump component seems to be an extra component superposed on the main pulse profile but does not appear periodically. The giant micro-pulses are time-resolved and have significant jitter in their arrival times. Their flux density distribution is best fitted by a power-law, indicating a link between these features and ‘classical’ giant pulses as observed for the Crab pulsar (PSR B0531 + 21), PSR B1937 + 21 and PSR B1821 - 24. We find that Vela contains a mixture of emission properties representing both ‘classical’ properties of radio pulsars (e.g. micro-structure, high degree of polarization, S-like position angle swing, orthogonal modes) and features which are most likely related to high-energy emission (e.g. extra profile components, giant micro-pulses). It hence represents an ideal test case to study the relationship between radio and high-energy emission in significant detail.

description: The performance of polypropylene glycol (PPG) and poly (methacrylic acid) (PMAA) as corrosion inhibitors for mild steel in acid solution was assessed by weight loss, electrochemical (electrochemical impedance spectroscopy, linear polarization resistance and potentiodynamic polarization), and surface analysis (water contact angles) techniques. Results obtained showed that both polymers inhibited mild steel corrosion but PPG was the best inhibitor. Inhibition efficiency increased with the increase in inhibitor concentration but decreased with temperature rise. Polarization results show that both PPG and PMAA behaved as a mixed-type inhibitors. The adsorption of the polymers onto the mild steel surface followed Temkin adsorption isotherm model. The variation of inhibition efficiency with temperature point toward physical adsorption which is supported by the kinetic and thermodynamic parameters derived from the experimental data. Water contact angle measurement results show that the polymers were adsorbed onto the mild steel surface.

description: Despite the importance of maize as a staple crop for food security in Africa, yields in the region are very low in comparison to the rest of the world. To keep up with growing demand, increasing the productivity of Africa’s smallholder farmers, who produce 75 percent of Africa’s maize, is crucial. New crop modelling results suggest that by implementing improved crop management practices, notably supplementary irrigation schemes and fertilizer use, current yields in Africa could potentially double at many locations. Policy makers and researchers should further investigate the applicability of these findings to regional contexts, and build the capacity of farmers in each country to adopt and sustainably apply the most effective combination of management practices.

description: This study presents an investigation on the tensile behaviour of heat-treated titanium alloy (Ti6Al4V) parts, which have been manufactured by Selective Laser Melting (SLM) additive manufacturing. The parts were heat treated at a temperature of 850ºC for 2 hours with and without Argon inert gas in a vacuum furnace. The tensile properties of the SLM samples with and without heat treatment have been compared to evaluate the mechanical performance of the 3D printed samples. The ultimate tensile strength (UTS) of as built Ti6Al4V part was found to be1175 MPa. The UTS of heat-treated Ti6Al4V sample in vacuum without Argon gas was found to be 750MPa, while the UTS of heat-treated sample in vacuum with Argon gas was recorded as 980MPa. These values compare well with other published values of UTS for SLM built Ti6Al4V alloys with similar heat-treated conditions. The work also studied the microhardness of all the samples and compared the values with each other and found that the heat treated sample have lower average Vickers hardness values compared to as built samples.

description: To review the effectiveness of isokinetic training as an alternative method to traditional isotonic resistance training. Researchers examined data from PubMed, CENTRAL, MEDLINE COMPLETE, and Web of Science until February 2023. A total of 365 entries were obtained from databases, including studies that analyzed the effects of isokinetic vs. isotonic-based rehabilitation in athletes (16–50 years) after a surgical knee intervention. Return to sport (RTS), strength of the flex/extensor compartment of the thigh, muscle mass of the thigh, and knee function were screened as main outcomes. Two reviewers independently screened the studies for eligibility and assessed the risk of bias of the included ones. Six studies involving 181 athletes were included. Isokinetic training demonstrated significant benefits in peak torque for knee flexor-extensor muscles in four studies. Two studies favored isokinetic training over isotonic for strength. Muscle mass findings were mixed, with one study favoring isokinetic significantly and two showing no significant differences. In terms of returning to sport, the isotonic group displayed slightly better limb symmetry index values, but without significance. Isokinetic training outperformed isotonic in two functionality questionnaire studies, while two others showed no significant differences. Isokinetic training appears equally, if not more effective than isotonic, for restoring strength balance between hamstrings and quadriceps. This could lead to more favorable muscle mass changes. Isokinetic training also parallels isotonic rehabilitation for functional outcomes and meeting return-to-sport criteria. Therefore, isokinetic training should be included as one of the main strength restoration strategies after knee surgery, especially in early and middle rehabilitation stages. The present systematic review was registered on PROSPERO (registration number: CRD42022370398).

description: Abstract

This study investigates the relationship between employee fit with organizational culture and its impact on job satisfaction, performance, and retention. Drawing on a sample of 46 participants from various professional backgrounds, the research explores how alignment between individual personality traits and organizational values influences key workplace outcomes. Using a mixed-methods approach—including structured surveys and open-ended interviews—the study examines employees’ perceptions of cultural compatibility and its effect on their motivation and engagement levels. Statistical analysis was conducted using SPSS to test three core hypotheses concerning the effects of cultural fit on retention, job performance, and satisfaction. Although the results did not yield statistically significant support for the hypotheses, the findings offer valuable qualitative insights into employee attitudes and suggest that perceived cultural alignment does influence workplace behavior and morale. The study concludes with practical recommendations for leaders and human resource professionals to strengthen organizational culture and improve employee experiences through strategic hiring, inclusive leadership, and communication practices.

description: Habitat restoration for inland trout (family Salmonidae) is common across western North America, but planners rarely consider disease risk when prioritizing restoration sites. Whirling disease is a parasitic infection caused by the invasive myxosporean parasite Myxobolus cerebralis and has been implicated in declines of wild trout populations across western North America. For planners to consider disease, disease risk needs to be predictable across the landscape and influence restoration outcomes. We collated the history of whirling disease infection severity scores on the MacConnell–Baldwin scale from sentinel cage studies for hatchery Rainbow Trout Oncorhynchus mykiss in the Blackfoot River basin from 1998 to 2009. At these same sites, we performed reach-scale geomorphic assessments, derived landscape variables from GIS data layers, and assembled fish composition data. We examined relationships between the severity of infection and several landscape-scale and reach-scale variables for 13 basin-fed streams in the Blackfoot River basin of west-central Montana using classification and regression tree analyses. In our data set, valley slope and forest cover were the best predictors of fine sediment. Both spring creeks and gently sloping alluvial basin-fed tributaries to the Blackfoot River basin with higher proportions of fine sediment (particle size < 0.85 mm) were associated with a high severity (≥ grade 3) of infection. Additionally, we explored differences in trout species composition (i.e., susceptible versus resistant species) before and after the whirling disease enzootic using seven basin-fed streams and two spring creeks. We did not detect trout community shifts from susceptible to disease-resistant salmonids in basin-fed disease-positive streams. However, spring creeks showed a negative trend in disease-susceptible salmonids after the whirling disease enzootic. Disease risk appears to be predictable across the landscape and may limit possible restoration outcomes by influencing species composition in spring creeks.Received December 20, 2013; accepted March 16, 2015.

description: We present AEGIS-Net, a novel indoor place recognition model that takes in RGB point clouds and generates global place descriptors by aggregating lower-level color, geometry features and higher-level implicit semantic features. However, rather than simple feature concatenation, self-attention modules are employed to select the most important local features that best describe an indoor place. Our AEGIS-Net is made of a semantic encoder, a semantic decoder and an attention-guided feature embedding. The model is trained in a 2-stage process with the first stage focusing on an auxiliary semantic segmentation task and the second one on the place recognition task. We evaluate our AEGIS-Net on the ScanNetPR dataset and compare its performance with a pre-deep-learning feature-based method and five state-of-the- art deep-learning-based methods. Our AEGIS-Net achieves exceptional performance and outperforms all six methods.
