Automated apparatus for gas solubility measurements
An automated apparatus based on the Ben-Naim-Baer and Tominaga et al. designs [A. Ben-Naim, S. Baer, Trans. Faraday Soc. 59 (1963) 2735-2738; T. Tominaga, R. Battino, H.K. Gorowara, R.D. Dixon, J. Chem. Eng. Data 31 (1986) 175-180] has been implemented for measurements of gas solubilities in liquids under atmospheric pressure and room temperatures. The uncertainty in the measurement of gas solubilities was estimated from the uncertainties in the directly measured quantities using the error propagation law. The accuracy of the experimental method was checked by measuring the solubility of carbon dioxide and nitrous oxide in water in the range TÂ =Â (290 to 303)Â K, being found to be 0.6%. A precision of the same order of magnitude was achieved.http://www.sciencedirect.com/science/article/B6WHM-4NYSXR7-2/1/adfe1ea651a5aee6dce7d49f424899b
Multispectral Indices for Wildfire Management
This paper highlights and summarizes the most important multispectral indices
and associated methodologies for fire management. Various fields of study are
examined where multispectral indices align with wildfire prevention and
management, including vegetation and soil attribute extraction, water feature
mapping, artificial structure identification, and post-fire burnt area
estimation. The versatility and effectiveness of multispectral indices in
addressing specific issues in wildfire management are emphasized. Fundamental
insights for optimizing data extraction are presented. Concrete indices for
each task, including the NDVI and the NDWI, are suggested. Moreover, to enhance
accuracy and address inherent limitations of individual index applications, the
integration of complementary processing solutions and additional data sources
like high-resolution imagery and ground-based measurements is recommended. This
paper aims to be an immediate and comprehensive reference for researchers and
stakeholders working on multispectral indices related to the prevention and
management of fires

Investigating mathematical models of immuno-interactions with early-stage cancer under an agent-based modelling perspective
Many advances in research regarding immuno-interactions with cancer were developed with the help of ordinary
differential equation (ODE) models. These models, however, are not effectively capable of representing problems
involving individual localisation, memory and emerging properties, which are common characteristics of cells and
molecules of the immune system. Agent-based modelling and simulation is an alternative paradigm to ODE
models that overcomes these limitations. In this paper we investigate the potential contribution of agent-based
modelling and simulation when compared to ODE modelling and simulation. We seek answers to the following
questions: Is it possible to obtain an equivalent agent-based model from the ODE formulation? Do the outcomes
differ? Are there any benefits of using one method compared to the other? To answer these questions, we have
considered three case studies using established mathematical models of immune interactions with early-stage
cancer. These case studies were re-conceptualised under an agent-based perspective and the simulation results
were then compared with those from the ODE models. Our results show that it is possible to obtain equivalent
agent-based models (i.e. implementing the same mechanisms); the simulation output of both types of models
however might differ depending on the attributes of the system to be modelled. In some cases, additional insight
from using agent-based modelling was obtained. Overall, we can confirm that agent-based modelling is a useful
addition to the tool set of immunologists, as it has extra features that allow for simulations with characteristics
that are closer to the biological phenomena
Smart river platform - river quality monitoring and environmental awareness
In the technology communication era, the use of the Internet
of Things (IoT) has become popular among other digital solutions,
since it offers the integration of information from several organisms and
at several sources. By means of this, we can access data from distant
locations and at any time. In the specific case of water monitoring, the
conventional outdated measurement methods can lead to low efficiency
and complexity issues. Hence, Smart systems rise as a solution for a
broad of cases. Smart River is a smart system platform developed to
optimize the resources and monitoring the quality of water parameters
of the Ferven¸ca river. The central solution is based at Centro Ciˆencia
Viva de Bragan¸ca (CCVB), one of the 21 science centers in Portugal
that aims to promote the preservation and environmental awareness for
the population. By using the IoT technologies, the system allows realtime
data collection with low cost and low energy consumption, being
a complement of existing projects that are being developed to promote
the ecological importance of natural resources. This paper covers sensor
module selection for data collection inside the river and data storage.
The parameters of the river are visualized using a program developed in
Unity engine to present data averages and comparison between weeks,
months, and years.This work has also been supported by Fundação La Caixa within the Project Scope: Natureza Virtual, and FCT - Fundação para a Ciência e Tecnologia within the Project Scope: UIDB/05757/2020.info:eu-repo/semantics/publishedVersio

Multi-method and multilevel assessments of interactions in families with autistic children
The workshop are focused on multi-method assessment and clinical intervention to promote parents-child relationship in ASD. Mazzoni and colleagues have presented a study on co-parenting, aimed to explore quality of triadic interactions, co-parental alliance and interactive behaviors in a sample of 29 families with ASD children. A multi-method approach was used and three observational procedures were compared: the LTP, the CFRS and a microanalysis of mother-father-child interactive behaviors. Findings of this studies show the usefulness of a multi-method approach in order to assess the quality of family interaction with ASD children. Observational tools are useful to detect strenghts and weakenesses, helping parents to improve the relationship with ASD children through video-feedback based interventions.Introduction Treatments of children with ASD are mainly focused on promoting children’s skills rather than parents-child relationship.
The impairments of communication and social interaction impact negatively on parenting, on child’s development and on co-parenting
relationship. To date, new techniques of family observation allow to assess strenghts and weaknesses in parents-child relationship.
Method The workshop will focus on multi-method assessment and clinical intervention to promote parents-child relationship in ASD.
Two studies and clinical cases will be presented. Mazzoni and colleagues will present a study on co-parenting, aimed to explore quality
of triadic interactions, co-parental alliance and interactive behaviors in a sample of 29 families with ASD children. A multi-method
approach was used and three observational procedures were compared: the LTP, the CFRS and a microanalysis of mother-father-child
interactive behaviors. Fachada and colleagues will present a study based
