AbstractWe examine the flow of Casson hybrid nanofluid (Cu+/) through a Riga plate sensor with perforations that act as an electromagnetic actuator. The hypodicarbonous acid is considered a base fluid. The impact of Arrhenius chemical kinetics and viscous dissipation are taken into account during the dynamics. The problem is formulated by considering the heat and mass transfer. An appropriate scaling is used to reduce the complexity of the problem, and further transform it into a system of ordinary differential equations (ODEs). The reduced system is further set for the first‐order system of equations that are analyzed with the Artificial Neural Network (ANN) which is trained with the Levenberg–Marquardt algorithm. The results for the state variables are displayed through graphs and tables by performing 1000 independent iterations with tolerance and . The Hartman, Casson, and Richardson numbers with their increasing values enhance the velocity profile. The chemical reaction parameter and the Prandtl number decline the thermal and concentration profiles, respectively. The Statistical analysis in the form of regression and histograms is also carried out in each case. The absolute error (AE) ranges up to and validations that range up to are presented for the varying values of each parameter. A comparative analysis of the nanofluid (NF) and hybrid nanofluid (HNF) is performed in each case study. The results for skin friction and Nusselt number are displayed numerically in the form of tables and are compared with the available literature, where the accuracy and performance of ANN are proved.

Good Practice-Beispiele aus Europa
Authors: Wrighton Susanne 
Published: July 2024

ZusammenfassungDie zunehmende Urbanisierung in Europa stellt Städte vor eine wachsende Herausforderung: Wie kann der stetig steigende Verkehr bewältigt werden, ohne dabei die Umwelt und die Lebensqualität der Einwohner:innnen zu beeinträchtigen? Meine Kollegen und Kolleginnen und ich haben uns diese Frage bereits 2010 gestellt und im Folgenden drei europäische Projekte initiiert und umgesetzt, die maßgeblich zum derzeitigen Lastenrad-Boom beigetragen haben. Denn, wie sich über das letzte Jahrzehnt mehr und mehr gezeigt hat, Lastenräder sind für Städte eine der vielversprechendsten Lösungen, die als nachhaltige Alternative zu herkömmlichen Liefer- und Transportfahrzeugen dienen. Aber auch in der privaten Logistik (Transport von Einkäufen oder Freizeitmaterialien) und besonders im Kindertransport haben Lastenräder ausnehmend hohes Potenzial (Reiter und Wrighton 2012; Wrighton und Reiter 2016). In diesem Kapitel soll die wachsende Rolle von Lastenrädern in europäischen Städten anhand von Good Practice-Beispielen demonstriert und ihre Auswirkungen auf Stadtplanung, Wirtschaft und Umwelt beleuchtet werden. Von den ersten zaghaften Versuchen bis hin zu umfassenden Verkehrsstrategien wird untersucht, wie Städte Lastenräder einsetzen, um den Verkehr zu entlasten und gleichzeitig eine lebenswerte und nachhaltige Zukunft zu gestalten.

AbstractThe study of microalgal communities is critical for understanding aquatic ecosystems. These communities primarily comprise diatoms (Heterokontophyta), with two methods commonly used to study them: Microscopy and metabarcoding. However, these two methods often deliver different results; thus, their suitability for analyzing diatom communities is frequently debated and evaluated. This study used these two methods to analyze the diatom communities in identical water samples and compare the results. The taxonomy of the species constituting the diatom communities was confirmed, and both methods showed that species belonging to the orders Bacillariales and Naviculales (class Bacillariophyceae) are the most diverse. In the lower taxonomic levels (family, genus, and species), microscopy tended to show a bias toward detecting diatom species (Nitzschia frustulum, Nitzschia inconspicua, Nitzschia intermedia, Navicula gregaria, Navicula perminuta, Navicula recens, Navicula sp.) belonging to the Bacillariaceae and Naviculaceae families. The results of the two methods differed in identifying diatom species in the communities and analyzing their structural characteristics. These results are consistent with the fact that diatoms belonging to the genera Nitzschia and Navicula are abundant in the communities; furthermore, only the Illumina MiSeq data showed the abundance of the Melosira and Entomoneis genera. The results obtained from microscopy were superior to those of Illumina MiSeq regarding species-level identification. Based on the results obtained via microscopy and Illumina MiSeq, it was revealed that neither method is perfect and that each has clear strengths and weaknesses. Therefore, to analyze diatom communities effectively and accurately, these two methods should be combined.

Published: July 2024

AbstractIn pharmaceutical manufacturing, ensuring product safety involves the detection and identification of microorganisms with human pathogenic potential, including Burkholderia cepacia complex (BCC), Escherichia coli, Pseudomonas aeruginosa, Salmonella enterica, Staphylococcus aureus, Clostridium sporogenes, Candida albicans, and Mycoplasma spp., some of which may be missed or not identified by traditional culture-dependent methods. In this study, we employed a metagenomic approach to detect these taxa, avoiding the limitations of conventional cultivation methods. We assessed the groundwater microbiome’s taxonomic and functional features from samples collected at two locations in the spring and summer. All datasets comprised 436–557 genera with Proteobacteria, Bacteroidota, Firmicutes, Actinobacteria, and Cyanobacteria accounting for > 95% of microbial DNA sequences. The aforementioned species constituted less than 18.3% of relative abundance. Escherichia and Salmonella were mainly detected in Hot Springs, relative to Jefferson, while Clostridium and Pseudomonas were mainly found in Jefferson relative to Hot Springs. Multidrug resistance efflux pumps and BlaR1 family regulatory sensor-transducer disambiguation dominated in Hot Springs and in Jefferson. These initial results provide insight into the detection of specified microorganisms and could constitute a framework for the establishment of comprehensive metagenomic analysis for the microbiological evaluation of pharmaceutical-grade water and other non-sterile pharmaceutical products, ensuring public safety.

Abstract
Background
Intraoperative laparoscopic ultrasonography (LUS) or intraoperative cholangiography (IOC) can be used for visualisation of the biliary tract during laparoscopic cholecystectomy. The aim of this systematic review was to compare use of LUS with IOC.

Methods
PubMed, Embase, the Cochrane Library, and Web of Science were searched (last update: April 2024). PICO: P = patients undergoing intraoperative imaging of the biliary tree during laparoscopic cholecystectomy for gallstone disease; I = intervention: LUS; C = comparison: IOC; O = outcomes: mortality, bile duct injury, retained gallstone, conversion to open cholecystectomy, procedural failure, operation time including imaging time. Included articles were critically appraised using checklists. Conclusions were based on studies without major risk of bias. Meta-analyses were performed using random effects models. Certainty of evidence was assessed according to GRADE.

Results
Sixteen non-randomised studies met the PICO. Two before/after studies (594 versus 807 patients) contributed to conclusions regarding mortality (no events; very low certainty evidence), bile duct injury (1 versus 0 events; very low certainty evidence), retained gallstone (2 versus 2 events; very low certainty evidence), and conversion to open cholecystectomy (6 versus 21 events; risk ratio: 0.38 (95% confidence interval: 0.15–0.95); I2 = 0%; low certainty evidence). Seven additional studies, using intra-individual comparisons, contributed to conclusions regarding procedural failure; risk ratio: 1.12 (95% confidence interval: 0.70–1.78; I2 = 83%; very low certainty evidence). No studies reported operation time. Mean imaging time for LUS and IOC, reported in 12 studies, was 4.8‒10.2 versus 10.9‒17.9 min (mean difference: − 7.8 min (95% confidence interval: − 9.3 to − 6.3); I2 = 95%; moderate certainty evidence).

Conclusion
It is uncertain whether there is any difference in mortality/bile duct injury/retained gallstone using LUS compared with IOC, but LUS may be associated with fewer conversions to open cholecystectomy and is probably associated with shorter imaging time.

Authors: Clapp Benjamin L. , Billy Helmuth , Lutfi Rami E. , Pan I.-Wen 
Published: July 2024

Abstract
Background
Few studies have evaluated the use of laparoscopic staplers in robotic procedures (bedside stapling, BS). This study aims to evaluate the effectiveness of BS compared with robotic staplers (RS) in bariatric robotic procedures.

Methods
Patients who underwent robotic sleeve gastrectomy or gastric bypass elective procedures between 1/1/2021 and 12/31/2021 were extracted from PINC AI™ Healthcare Data. The following clinical outcomes were compared: blood transfusion, bleeding, anastomotic leak, intensive care unit (ICU) visit, and 30-day readmission, operating room (OR) time, inpatient costs, and length of stay. We evaluated baseline balance in BS and RS and bivariate association between covariates and outcomes using Chi-square or Fisher exact test and t-test or ANOVA. Multivariable general linear mixed models (GLMMs) with respective gamma or binomial distribution and log-link function were used to obtain adjusted outcomes variations between BS and RS.

Results
Total of 7268 discharges were included with 1603 (22.1%) BS and 5665 (77.9%) RS cases. RS cases consisted of a higher number of patients who were Hispanic (17.0% vs. 9.4%), had Medicaid (26.9% vs. 19.4%) and underwent sleeve gastrectomy (68.4% vs. 53.5%). Higher proportions of RS cases were done by providers in Northeast region (35.5% vs. 24.3%), smaller size (< 500 beds; 71.1% vs. 52.3%), and teaching hospitals (59.4% vs. 39%). The adjusted outcomes variations demonstrated that patients that had RS were significantly more likely to have blood transfusions, ICU stays, increased ORT (19 min) and costs ($1273). Sensitivity analysis showed similar results, except no significant differences in blood transfusion rates in both groups.

Conclusions
Bedside staplers significantly reduce healthcare resource utilization with equivalent effectiveness and fewer ICU stays compared to robotic staplers.

Abstract
Background
Anastomotic leakage (AL) is a dreaded complication following colorectal cancer surgery, impacting patient outcome and leads to increasing healthcare consumption as well as economic burden. Bowel perfusion is a significant modifiable factor for anastomotic healing and thus crucial for reducing AL.

Aims
The study aimed to calculate a cut-off value for quantified laser speckle perfusion units (LSPUs) in order to differentiate between ischemic and well-perfused tissue and to assess inter-observer reliability.

Methods
LSCI was performed using a porcine ischemic small bowel loop model with the PerfusiX-Imaging® system. An ischemic area, a well-perfused area, and watershed areas, were selected based on the LSCI colormap. Subsequently, local capillary lactate (LCL) levels were measured. A logarithmic curve estimation tested the correlation between LSPU and LCL levels. A cut-off value for LSPU and lactate was calculated, based on anatomically ischemic and well-perfused tissue. Inter-observer variability analysis was performed with 10 observers.

Results
Directly after ligation of the mesenteric arteries, differences in LSPU values between ischemic and well-perfused tissue were significant (p < 0.001) and increased significantly throughout all following measurements. LCL levels were significantly different (p < 0.001) at both 60 and 120 min. Logarithmic curve estimation showed an R2 value of 0.56 between LSPU and LCL values. A LSPU cut-off value was determined at 69, with a sensitivity of 0.94 and specificity of 0.87. A LCL cut-off value of 3.8 mmol/L was found, with a sensitivity and specificity of 0.97 and 1.0, respectively. There was no difference in assessment between experienced and unexperienced observers. Cohen’s Kappa values were moderate to good (0.52–0.66).

Conclusion
Real-time quantification of LSPUs may be a feasible intraoperative method to assess tissue perfusion and a cut-off value could be determined with high sensitivity and specificity. Inter-observer variability was moderate to good, irrespective of prior experience with the technique.

AbstractObjectivesThe aim of this study was to evaluate the peri-implant perfusion, such as oxygen saturation, the relative amount of hemoglobin, and blood flow, in implants placed in pristine bone and avascular and microvascular grafts using a non-invasive measurement method.Materials and methodsA total of 58 patients with 241 implants were included. Among them, 106 implants were based in native bone (group I), 75 implants were inserted into avascular bone grafts (group II), and 60 implants were placed in microvascular bone grafts (group III). Gingival perfusion was measured using laser Doppler flowmetry and tissue spectrophotometry (LDF-TS). Implants with signs of gingival inflammation were excluded to analyze healthy implant perfusion in different bony envelopes.ResultsThe mean values for oxygen saturation, relative hemoglobin levels, and blood flow did not differ significantly between the groups (p = 0.404,p = 0.081, andp = 0.291, respectively). There was no significant difference in perfusion between implants that were surrounded by mucosa and implants based within cutaneous transplants (p = 0.456;p = 0.628, andp = 0.091, respectively).ConclusionNo differences in perfusion were found between implants inserted into native bone and implants involving bone or soft tissue augmentation. However, implants based in avascular and microvascular transplants showed higher rates of peri-implant inflammation.Clinical relevancePeri-implant perfusion seems to be comparable for all implants after they heal, irrespective of their bony surroundings. Although perfusion does not differ significantly, other factors may make implants in avascular and microvascular transplants vulnerable to peri-implant inflammation.
Exploring the correlation between courier workload, service density and distance with the success of last-mile and first-mile reverse logistics

Published: July 2024

AbstractGiven the recent surge in online sales, particularly accentuated by the health crisis in 2020 and 2021, companies operating in the retail sector have increasingly recognised the importance of business-to-consumer (B2C) distribution. Consequently, last-mile logistics optimization has garnered increased attention in both academic and industry contexts. In this study, we examine the relationship between the workloads of couriers and their proficiency in executing assigned services in a B2C last-mile and first-mile reverse logistics environment. Additionally, we evaluate the connection between service density in an area and the distance between warehouses and service points with completion rates among couriers. By analysing a dataset corresponding to the deliveries and collections made in Madrid in 2021, we identify significant and moderate correlations between the couriers’ workloads and service completion rate. It should be noted that the correlations of completion rate with distance and visit frequency to each area are weak, yet statistically significant.
Rock avalanches in northeastern Baffin Island, Canada: understanding low occurrence amid high hazard potential

Published: July 2024

AbstractRock avalanches in fjord environments can cause direct catastrophic damage and trigger secondary submarine landslides and tsunamis. These are well-documented in Greenland, Norway, and Alaska but have gone largely unreported in the extensive fjord terrain of the eastern Canadian Arctic. We provide the first inventory of rock avalanche deposits in northeastern Baffin Island—a region characterized by moderate to high seismic hazard, steep and high-walled fjords and glacial valleys, active deglaciation, and observed climate warming. Over a broad study area of ~60,000 km2, one sixth of the terrain had sufficient slope height and gradient to potentially generate rock avalanches. Within that hazard zone, we identified eight rock avalanche deposits at six locations. Only three rock avalanche deposits at two locations are dated, using aerial imagery (1958-present), to the last century while five deposits at four locations are inferred as syn- to post-glacial, likely occurring shortly after local debuttressing. These total numbers fall well below documented inventories from Greenland, Norway, and Alaska. We hypothesize that (1) continuous permafrost persists throughout this region and continues to act as a stabilizing factor and (2) rock mass quality is high in areas of most extreme relief contrast within the study region relative to analogous high-latitude fjord systems such as those in southwestern Greenland. We suggest that Baffin Island is currently in a period of quasi-stability that follows the intense instability during initial deglaciation, yet precedes the higher anticipated slope instability that may occur during permafrost degradation.
Glimpses of embodied utopias, why Moroccan and Swiss farmers engage in alternative agricultures
Authors: Mathez Andrea 
Published: July 2024

Abstract
Geographies of food are not only shaped by political economic forces but also by individuals who resist dominant ways of subjectivation. Based on ethnographic research on forty-seven agroecological farms in Switzerland and Morocco, this article proposes a philosophical reconsideration of the role of utopia, hope and enchantment in shaping people’s actions. It contributes to the understanding of the emotional, spiritual and embodied experiences that lead farmers to engage in alternative agricultures at the margins of state planning and agro-industry. The adoption of an etic research approach to ‘alternativity’ allows me to capture ‘quiet alternativities’, or farming experiences with beneficial socio-ecological outcomes but which are not represented as alternative or disruptive by the farmers themselves. This is especially important for Swiss and Moroccan farmers who do not always identify with a social movement or express any explicit opposition to agricultural policies and the dominant agri-food system, although their practices may effectively incorporate an alternative experience from where to envision different agri-cultures. Drawing from diverse conceptions of utopia, hope and enchantment, I unravel different manifestations of utopia as mental creations of ‘no-where’ and as embodied experiences of ‘no-when’. This enables me to attend to ‘quiet expressions’ of hope manifested not in speech but in daily practices and to discuss farmers’ motives to engage in alternative agricultures, despite a sometimes bleak outlook. I theorise these multiple experiences as ‘glimpses of utopias’ to explore the embodied and embedded dimensions of utopia to broaden what utopia can mean beyond purely speculative thinking.
