Use of a voith flotation cell for removal of lipophilic extractives and Mn ions from spruce thermomechanical pulping process waters
Authors: Zasadowski Dariusz , Hedenström Erik , Edlund Håkan , Norgren Magnus
Published: June 2023

The effects of a chelating surfactant and different foaming agents on the efficiency of cleaning process waters from a thermomechanical pulp (TMP) mill were studied in a Voith flotation cell. Turbidity measurements and gas chromatography were used to determine the removal extent and characteristics of dissolved and colloidal substances (DisCo). The metal ion content in the process waters before flotation and the metal chelate removal after flotation were determined using inductively coupled plasma-optical emission spectrometry (ICP-OES). FiberLab™ equipment was used to characterize changes in the size of fibers present in the process waters. The results indicate that a decrease in turbidity of up to 91% and the removal of 80% of lipophilic extractives in the TMP water could be obtained using a single-stage flotation unit. Furthermore, the foam fraction was within 5% of the initial volume, and 100% of the Mn2+/chelating surfactant complex added to the TMP water was removed.

Published: June 2023

The heat treatment of softwood (i.e. spruce, pine, fir, and larch) may result in significant colour changes. During this study Scots pine and spruce samples were steamed and analysed for their altered hue and lightness. Treatments included: 0 to 22 days of steaming time at a temperature range of 70 to 100°C. The outcome included a variety of colours between the initial hues and brownish tint. These new colours are similar to that of aged furniture and indoor wooden structures. Consequently, properly steamed softwood may be used to repair historical artefacts and relic furniture. Besides restoration, steamed stocks are excellent sources for manufacture of periodical furniture, where the aged appearance has aesthetical value. Results however, indicated that steaming at a temperature above 90 ˚C has a bleaching effect, i.e. the coloured chemical components formed by moderate steaming may be removed. Furthermore, we observed a linear correlation between lightness and colour hue at all steaming times and temperatures.

Published: June 2023

Three laccases, functioning in mild acidic, and one in slightly alkaline conditions, were evaluated in order to reduce low-molecular phenolic VOCs of kraft lignins, which could be used in lignin/natural fibers composites. The potential of a sulfhydryl oxidase to catalyze the oxidation of sulfur containing VOCs (thiols) was also tested in combination with the laccase-catalyzed oxidation. In addition, oxidation at alkaline pH at room temperature that may induce polymerization of phenolics in an analogous manner to the laccase-catalyzed reaction was investigated. Enzyme reactivity towards lignin was evaluated as consumption of oxygen in the reaction solution. The effect of treatments on VOC reduction was determined both by sensing (odorimetry) and chemical (TD-GC/MS, SEC) analyses. Laccases, Lcc2, and MaL from Thielavia arenaria and Melanocarpus albomyces, respectively, showed potential in reducing odors. The most promising results were obtained by oxidizing lignin with O2 at alkaline pH. However, the odor threshold values of the main VOC compounds are extremely low, which poses a challenge to VOC reduction.

The features of refractory lining’s wear of “ladle – furnace” unit at work on metallurgical mini-plant with intensive stirring of liquid metal by gas and electromagnetic field is studied. It was established that the most affected areas are slag zone, ladle’s bottom, as well as side wall, near which the electromagnetic stirrer is located. The stability of these areas determines the duration of the ladle working between repairs. Recommendations for recovery of the lining’s working layer have been developed. Also, there are formulated the requirements for rationalization of melt stirring modes. Theoretical studying of influence of electromagnetic stirring on heat & mass transfer processes in liquid metal bath of metallurgical aggregates (in particular, during homogenization of alloy in free turbulence mode at input of additives) was investigated. New electromagnetic stirrer was designed in the PTIMA NASU, and it is proposed for technologies of melting and finishing of alloys. The stirrer creates the pulsating magnetic field, and its force lines spread equally intensively both in the horizontal and vertical planes. It is shown that design of developed stirrer, its power supply by industrial frequency 50 Hz, and physical nature of the generated field’s action provide the simplicity of its making and operation. So, new stirrer has essential technical, economic and technological advantages in comparison with known stirrers of travelling magnetic field at the same parameters of electromagnetic systems. Joint research performed by specialists of the PTIMA NASU and IED NASU with using mathematical modeling and experiments on aluminum melt showed the following. It is possible to realize a wide range of stirring modes, both intensity and melt movement directions. Thus, the application of developed electromagnetic stirrer in the “ladle – furnace” units will allow to significantly expand the possibilities for finishing liquid alloys on chemical composition and temperature, especially at small metallurgical plants.

Authors: Kulkarni Neha S. , Jadhav Balaji J.
Published: June 2023

Background: Thyroid dysfunction is one of the most common endocrine disorders affecting women of reproductive age group. There is a debate among obstetricians about universal versus targeted screening for hypothyroidism during pregnancy. Therefore, we conducted this study with aim to highlight the need for universal screening of pregnant women for hypothyroidism.
Methods: This was prospective analytical study involving 200 pregnant women conducted in a tertiary care hospital in Mumbai from January 2018 to December 2019. Thyroid-stimulating hormone (TSH) was done as a screening test. Estimation of free T3 (FT3) and free T4 (FT4) are advised if TSH was found abnormal. Patients were followed up throughout the pregnancy and postpartum up to 6 weeks. Study parameters were assessed in both mother and neonate and statistical analysis was done.
Results: Pregnancy induced hypertension (PIH) was observed in 13% of study population. Premature labour was observed in 11% of study population. Recurrent abortion was observed in 7% of study population. Postpartum haemorrhage (PPH) was observed in 4% of study population. Anaemia was observed in 69% of study population. Neonatal intensive care unit (NICU) admission was observed in 17% of study population. Neonatal hypo/ hyperthyroidism was observed in 3% of study population.
Conclusions: Pregnant females should routinely be screened for thyroid functions to detect hypothyroidism and be given adequate treatment to prevent maternal and foetal complications. Adequate treatment and regular follow up will improve the maternal and foetal outcomes.

Evaluating the Psychometric Properties and Clinical Utility of a Digital Psychosocial Self-Screening Tool (HEARTSMAP-U) for Postsecondary Students: Prospective Cohort Study
Authors: Virk Punit , Arora Ravia , Burt Heather , Finnamore Caitlin , Gadermann Anne , Barbic Skye , Doan Quynh
Published: June 2023

Background

Existing screening tools for mental health issues among postsecondary students have several challenges, including a lack of standardization and codevelopment by students. HEARTSMAP-U was adapted to address these issues.

Objective

This study aimed to evaluate the suitability of HEARTSMAP-U as a self-screening tool for psychosocial issues among postsecondary students by evaluating its validity evidence and clinical utility.

Methods

A prospective cohort study was conducted with University of British Columbia Vancouver students to evaluate HEARTSMAP-U’s predictive validity and convergent validity. Participating students completed baseline and 3-month follow-up assessments via HEARTSMAP-U and a clinician-administered interview.

Results

In a diverse student sample (n=100), HEARTSMAP-U demonstrated high sensitivity (95%-100%) in identifying any psychiatric concerns that were flagged by a research clinician, with lower specificity (21%-25%). Strong convergent validity (r=0.54-0.68) was demonstrated when relevant domains and sections of HEARTSMAP-U were compared with those of other conceptually similar instruments.

Conclusions

This preliminary evaluation suggests that HEARTSMAP-U may be suitable for screening in the postsecondary educational setting. However, a larger-scale evaluation is necessary to confirm and expand on these findings.
Comparing the Acceptability and Quality of Intervention Modalities for Suicidality in the Emergency Department: Randomized Feasibility Trial (Preprint)
Authors: Larkin Celine , Tulu Bengisu , Djamasbi Soussan , Garner Roscoe , Varzgani Fatima , Siddique Mariam , Pietro John , Boudreaux Edwin D
Published: June 2023

BACKGROUND

Emergency departments (EDs) manage many patients with suicide risk, but effective interventions for suicidality are challenging to implement in this setting. ReachCare is a technology-facilitated version of an evidence-based intervention for suicidal ED patients. Here, we present findings on the acceptability and quality of ReachCare in the ED, as well as a comparison of these measures across 3 potential delivery modalities

OBJECTIVE

Our aim was to test the feasibility of the ReachCare intervention in its entirety through conducting a pilot study with patients presenting with suicidality to the ED. We tested three different ways of receiving the ED-based components of ReachCare: (1) self-administered on the tablet app using a chatbot interface, (2) administered by an in-person clinician, or (3) administered by a telehealth clinician.

METHODS

In total, 47 ED patients who screened positive for suicide risk were randomly allocated to receive one of three delivery modalities of ReachCare in the ED: (1) self-administered on the patient-facing tablet app with a chatbot interface, (2) delivered by an in-person clinician, or (3) delivered by a telehealth clinician, with the latter two using a clinician-facing web app. We measured demographic and clinical characteristics, acceptability and appropriateness of the intervention, and quality and completeness of the resulting safety plans.

RESULTS

Patients assigned high ratings for the acceptability (median 4.00/5, IQR 4.00-4.50) and appropriateness (median 4.00/5, IQR 4.00-4.25) of ReachCare’s ED components, and there were no substantial differences across the 3 delivery modalities [H(acceptability)=3.90, P=.14; H(appropriateness)=1.05, P=.59]. The self-administered modality took significantly less time than the 2 clinician modalities (H=27.91, P<.001), and the usability of the self-administered version was in the “very high” range (median 93.75/100, IQR 80.00-97.50). The safety plans created across all 3 modalities were high-quality (H=0.60, P=.74).

CONCLUSIONS

Patients rated ReachCare in the ED as highly acceptable and appropriate regardless of modality. Self-administration may be a feasible way to ensure patients with suicide risk receive an intervention in resource constrained EDs. Limitations include small sample size and demographic differences between those enrolled versus not enrolled. Further research will examine the clinical outcomes of patients receiving both the in-ED and post-ED components of ReachCare.

Published: June 2023

Con el propósito de valorar la relevancia de la metacognición como proceso psicológico que incide en el aprendizaje de los estudiantes a lo largo de, y para toda la vida, se realiza el presente estudio. Se asumió la metodología de sistematización de las teorías y las prácticas psicopedagógicas más influyentes en el contexto educacional cubano, lo cual permitió identificar las regularidades y tendencias que caracterizan la sinergia entre estas categorías. Se plantea de manera explícita la revisión de distintas posturas de la Psicología y Pedagogía, como son: el humanismo, el cognitivismo y la postura histórico cultural para llevar a cabo la sistematización en torno a la comprensión teórico-metodológica y la formulación de estrategias de formación de la metacognición. Se destacan el constructivismo y el enfoque histórico cultural, que son las concepciones que más recursos de estimulación aportan a las tecnologías de metacognición desde este contexto. Del análisis crítico se concluye la necesidad de proponer una concepción holística y desarrolladora del aprendizaje que retome los aspectos positivos del conocimiento psicológico universal, aunque el trabajo no represente la completa sistematización de supuestos y tecnologías de la metacognición; y, se integre a una concepción de educación y desarrollo.

Physical and observational constraints on the anvil cloud area feedback
Authors: McKim Brett , Bony Sandrine , Dufresne Jean-Louis

Changes in anvil cloud area with warming are a leading source of
uncertainty in estimating the Earth’s climate sensitivity (Forster et al
2021). Most approaches to bounding this area feedback rely on climate
models or expert assessment. Here, we use observations and theory, a
“storyline approach”, to bound it. We first derive a simple but
quantitative expression for the anvil area feedback, which is shown to
depend on the present day, measurable cloud radiative effects and the
fractional change in anvil area with warming. Satellite observations
suggest an anvil cloud radiative effect of about ± 1
Wm, which requires the fractional change in anvil
area to be about ∓ 50 % K to
produce a feedback equal to its present-day lower bound. We use theory
and observations to show that the change in anvil area is closer to
about -4 % K. This rules out the
previous estimate of the area feedback and leads to our new estimate of
0.02 ± 0.07 WmK
which is many times weaker and more constrained. In comparison, we show
the anvil cloudy albedo feedback to be much less constrained. This poses
an obstacle for bounding the Earth’s climate sensitivity.
Implementation of Nickel and Copper as Cost-Effective Alternative Contacts in Silicon Solar Cells
Authors: Unsur Veysel
Published: June 2023

Efficient metal contact formation is pivotal for the production of
cost-effective, high-performance crystalline silicon (Si) solar cells.
Traditionally, screen-printed silver (Ag) contacts on the front surface
have dominated the industry, owing to their simplicity, high throughput,
and significant electrical benefits. However, the high cost associated
with using over 13-20mg/Wp of Ag can impede the development of truly
cost-effective solar cells. Therefore, there is an urgent need to
explore alternative, economically viable metals compatible with silicon
substrates. This study reports on the application of a contact stack
consisting of Ag, nickel (Ni), and copper (Cu) in Si solar cells. To
prevent Schottky contact formation, Ag is implemented as a seed layer,
while Ni and Cu form the metal bulk layer. The fabricated bi-layer stack
without selective emitter exhibits a maximum efficiency of
~21.5%, a fill factor of 81.5%, and an average contact
resistance of 5.88mΩ·cm for a monofacial PERC cell.
Microstructure analysis demonstrate that the metals within the contacts
remain distinct, and Cu diffusion into the silicon during the firing
process is absent. Consequently, printed bi-layer contacts emerge as a
promising alternative to Ag contacts, reducing the Ag consumption to
below 2.5mg/Wp per cell without compromising overall efficiency.
Development of a fast and accurate hybrid model for floodplain inundation simulations
Authors: Fraehr Niels , Wang Quan J , Wu Wenyan , Nathan Rory
Published: June 2023

High computational cost is often the most limiting factor when running
high-resolution hydrodynamic models to simulate spatial-temporal flood
inundation behaviour. To address this issue, a recent study introduced
the hybrid Low-fidelity, Spatial analysis, and Gaussian Process learning
(LSG) model. The LSG model simulates the dynamic behaviour of flood
inundation extent by upskilling simulations from a low-resolution
hydrodynamic model through Empirical Orthogonal Function (EOF) analysis
and Sparse Gaussian Process (Sparse GP) learning. However, information
on flood extent alone is often not sufficient to provide accurate flood
risk assessments. In addition, the LSG model has only been tested on
hydrodynamic models with structured grids, while modern hydrodynamic
models tend to use unstructured grids. This study therefore further
develops the LSG model to simulate water depth as well as flood extent
and demonstrates its efficacy as a surrogate for a high-resolution
hydrodynamic model with an unstructured grid. The further developed LSG
model is evaluated on the flat and complex Chowilla floodplain of the
Murray River in Australia and accurately predicts both depth and extent
of the flood inundation, while being 12 times more computationally
efficient than a high-resolution hydrodynamic model. In addition, it has
been found that weighting before the EOF analysis can compensate for the
varying grid cell sizes in an unstructured grid and the inundation
extent should be predicted from an extent-based LSG model rather than
deriving it from water depth predictions.

The movement of air masses within the troposphere transport a multitude
of particles, and hence generate air highway connecting distant areas at
the local, continental and global scales depending on the particle
properties and the atmospheric conditions. In this article we present an
approach and an accompanying web application called tropolink for
measuring the extent to which distant locations are potentially
connected by air-mass movement. This approach is based on the
computation of trajectories of air masses with the HYSPLIT atmospheric
transport and dispersion model, and on the computation of connection
frequencies, called connectivities, in the purpose of building
trajectory-based geographical networks. It is illustrated for different
spatial and temporal scales with three case studies related to plant
epidemiology. The web application that we designed allows the user to
easily perform intensive computation and mobilize massive archived
gridded meteorological data to build weighted directed networks. The
analysis of such networks allowed us for example to describe the
potential of invasion of a migratory pest beyond its actual
distribution. Our approach could also be used to compute geographical
networks generated by air-mass movement for diverse application domains,
e.g. to assess long-term risk of spread from sources of pollutants.

Published: June 2023

Objective

This case report describes the successful treatment of a patient with Crouzon syndrome with severe midfacial deficiency and malocclusion, including reverse overjet.

Materials and Methods

In Phase I treatment, maxillary lateral expansion and protraction were performed. In Phase II treatment, after lateral expansion of the maxilla and leveling of the maxillary and mandibular dentition, an orthognathic approach including simultaneous Le Fort I and III osteotomies with distraction osteogenesis (DO) was used to improve the midfacial deficiency.

Results

After DO, 12.0 mm of the medial maxillary buttress and 9.0 mm of maxillary (point A) advancement were achieved, which resulted in a favorable facial profile and stable occlusion.

Conclusion

Even after 8 years of retention, the patient's profile and occlusion were preserved without any significant relapse.
