Sovittelu työriidoissa
Authors: Koulu Risto
Published: March 2023

Sovittelu on osa työriitojen konfliktinhallintaa. Työriitojen sovittelua on perinteisesti tutkittu itsenäisenä ilmiönä ja sen ominaispiirteitä korostaen. Tämä on heijastanut vallitsevaa käsitystä työriitojen sovittelun erillistiestä. Työriitojen sovittelu ei ole ottanut vaikutteita muista sovittelujärjestelmistä; se ei myöskään ole antanut niille vaikutteita. Tästä syystä työriitojen sovittelu on vasta viime vuosina noussut teoreettisen konfliktitutkimuksen kohteeksi. Uusi tutkimus on löytänyt työriitojen sovittelusta lukuisia erikoisuuksia, jotka kaipaisivat uudelleenarvioimista. Tässä tutkimuksessa työriitojen sovittelu asetetaan oikeudellisen konfliktinhallinnan ja erityisesti sovittelun muodostamaan viitekehykseen. Näkökulma antaa tilaisuuden eri sovittelujärjestelmien keskinäiseen vertailuun. Samalla avautuu mahdollisuus arvioida nykyisen työriitojen sovittelujäijestelmän toimivuutta. Näin päästään ottamaan kantaa siihen, mitkä yleisen sovittelun menettelytavoista olisivat siirrettävissä työriitojen sovitteluun ja päinvastoin. Tutkimus päätyy konkreettisiin ehdotuksiin työriitojen sovittelun uudistamiseksi.
Assessment of the possibility of using iron-magnesium production waste for wastewater treatment from heavy metals (Cd2+, Zn2+, Co2+, Cu2+)
Authors: Antoninova Natalya , Sobenin Artem , Usmanov Albert , Shepel Ksenia
Published: March 2023

Relevant problems associated with treatment of industrial wastewater from heavy metal ions are considered. Due to industrial development, the amount of wastewater increases as well as the risks of heavy metals getting into surface and groundwater, accumulating in water bodies and becoming aggressive environmental pollutants, which affect the animal and human organisms. To assess the possibility of extracting metal ions (Cd2+, Zn2+, Co2+, Cu2+) from industrial wastewater and their further treatment, studies were carried out on redistribution of heavy metals in the “wastewater – waste” system using iron-magnesium production waste. Samples of the investigated waste weighing 0.1; 0.2; 0.5; 1; 1.5; 2 g were taken for wastewater volume of 50 ml per each subsample. Contact time varied from 5 to 180 min, waste fraction was 1 mm. The interaction process showed that the waste efficiently removes metal ions (Cd2+, Zn2+, Co2+, Cu2+) from industrial wastewater. The efficiency of removing a pollutant from the solution depends on the weight of the waste subsample, initial concentration of metal ions, and contact time.

Authors: Schmicker Marlen , Frühling Insa , Menze Inga , Glanz Wenzel , Müller Patrick , Noesselt Toemme , Müller Notger G.
Published: March 2023

Background:

Patients with subjective cognitive decline (SCD) report memory deterioration and are at an increased risk of converting to Alzheimer’s disease (AD) although psychophysical testing does not reveal any cognitive deficit.

Objective:

Here, gustatory function is investigated as a potential predictor for an increased risk of progressive cognitive decline indicating higher AD risk in SCD.

Methods:

Measures of smell and taste perception as well as neuropsychological data were assessed in patients with subjective cognitive decline (SCD): Subgroups with an increased likelihood of the progression to preclinical AD (SCD+) and those with a lower likelihood (SCD–) were compared to healthy controls (HC), patients with mild cognitive impairment and AD patients. The Sniffin’ Sticks test contained 12 items with different qualities and taste was measured with 32 taste stripes (sweet, salty, bitter, sour) of different concentration.

Results:

Only taste was able to distinguish between HC/SCD– and SCD+ patients.

Conclusion:

This study provides a first hint of taste as a more sensitive marker than smell for detecting preclinical AD in SCD. Longitudinal observation of cognition and pathology are necessary to further evaluate taste perception as a predictor of pathological objective decline in cognition.
Information, mereology and vagueness
Authors: Bittner Thomas
Published: March 2023

Classical systems of mereology identify a maximuml set of jointly exhaustive and pairwise disjoint (RCC5) relations. The amount of information that is carried by each member of this set of (crisp) relations is determined by the number of bits of information that are required to distinguish all the members of the set. It is postulated in this paper, that vague mereological relations are limited in the amount of information they can carry. That is, if a crisp mereological relation can carry N bits of information, then a vague mereological relation can carry only 1 ⩽ n < N bits. The aim of this paper is it to explore these ideas in the context of various systems of vague mereological relations. The resulting formalism is non-classical in the sense of quantum information theory.
Artificial Intelligence and the second trimester of pregnancy: A literature survey
Authors: Belciug Smaranda
Published: March 2023

Pregnancy is a wonderful period in every woman’s life. Every trimester comes with all sorts of emotions, good or bad. The second trimester is said to be the most pleasant one. Nevertheless, it comes with anxiety and stress. To eliminate these emotions, doctors perform a second trimester ultrasound. This is also called the second trimester morphology scan. This type of scan is important because it determines if the fetus is growing and developing at normal pace. The sonographer measures the baby’s size and weight, the fetal heart, brain, spine, skeleton, abdominal, pelvic, and thoracic organs. She/he also checks whether there are hard or soft genetic disorders markers, whether the amniotic fluid levels are normal or not, and determine the location of the placenta. All these verifications and estimations imply a good experience in fetal ultrasonography. Unfortunately, experienced sonographers are clustered in big city cities, and cannot be found in poor regions. In order for everybody to have access to premium fetal morphology ultrasounds, there is a need for artificial intelligence methods. Artificial Intelligence algorithms can signal possible anomalies, which an unexperienced sonographer might miss. The aim of this paper is to do a literature survey and present the state-of-the-art of the Artificial Intelligence applied in second trimester sonography.

Published: March 2023

Background:

There is increasing evidence that supplementation of S-adenosylmethionine (SAM) can improve cognitive function in animals and humans, although the outcomes are not always inconsistent.

Objective:

We conducted a systematic review and meta-analysis to evaluate the correlation between SAM supplementation and improved cognitive function.

Methods:

We searched studies in the PubMed, Cochrane Library, Embase, Web of Science, and Clinical Trials databases from January 1, 2002 to January 1, 2022. Risk of bias was assessed using the Cochrane risk of bias 2.0 (human studies) and the Systematic Review Center for Laboratory Animal Experimentation risk of bias (animal studies) tools; and evidence quality was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation. STATA software was employed to perform meta-analysis, and the random-effects models was used to evaluate the standardized mean difference with 95% confidence intervals.

Results:

Out of the 2,375 studies screened, 30 studies met the inclusion criteria. Meta-analyses of animal ( p = 0.213) and human ( p = 0.047) studies showed that there were no significant differences between the SAM supplementation and control groups. The results of the subgroup analyses showed that the animals aged ≤8 weeks ( p = 0.027) and the intervention duration >8 weeks ( p = 0.009) were significantly different compared to the controls. Additionally, the Morris water maze test ( p = 0.005) used to assess the cognitive level of the animals revealed that SAM could enhance spatial learning and memory in animals.

Conclusion:

SAM supplementation showed no significant improvement in cognition. Therefore, further studies are needed to assess the effectiveness of SAM supplementation.
Feature selection using fuzzy-neighborhood relative decision entropy with class-level priority fusion
Authors: Zhang Xianyong , Wang Qian , Fan Yunrui
Published: March 2023

Feature selection facilitates classification learning and can resort to uncertainty measurement of rough set theory. By fuzzy neighborhood rough sets, the fuzzy-neighborhood relative decision entropy (FNRDE) motivates a recent algorithm of feature selection, called AFNRDE. However, FNRDE has fusion defects for interaction priority and hierarchy deepening, and such fusion limitations can be resolved by operational commutativity; furthermore, subsequent AFNRDE has advancement space for effective recognition. For the measurement reinforcement, an improved measure (called IFNRDE) is proposed to pursue class-level priority fusion; for the algorithm promotion, the corresponding selection algorithm (called AIFNRDE) is designed to improve AFNRDE. Concretely, multiplication fusion of algebraic and informational measures is preferentially implemented at the class level, and the hierarchical summation generates classification-level IFNRDE. IFNRDE improves FNRDE, and its construction algorithm and granulation monotonicity are acquired. Then, IFNRDE motivates a heuristic algorithm of feature selection, i.e., AIFNRDE. Finally, relevant measures and algorithms are validated by table examples and data experiments, and new AIFNRDE outperforms current AFNRDE and relevant algorithms FSMRDE, FNRS, FNGRS for classification performances.

With the development of globalization, companies from all over the world are now more closely connected, and they all play different roles in the industry in which they are located. There are more and more companies in a complete supply chain, which can greatly influence the stability of the supply chain, presents certain challenges. Therefore, choosing suppliers with sustainable development capabilities, especially in the event of interruption, can ensure the stability of the entire supply chain, thereby enhancing the company’s image and competitive advantage in a large-scale competition. The sustainable supplier selection is a classical multiple attribute group decision making (MAGDM) issues. In this study, the dual probabilistic linguistic EDAS (DPL-EDAS) method is built based on the traditional EDAS method and dual probabilistic linguistic term sets (DPLTSs). Firstly, the DPLTSs is introduced. Then, combine the traditional EDAS method with DPLTSs information, the DPL-EDAS method is established and the computing steps for MAGDM are built. Finally, there are a numerical case involving sustainable supplier selection and some comparisons in this paper. The comparisons are used to illustrate advantages of DPL-EDAS method.

Published: March 2023

Coupled with both a political and a social crisis, the conflict which Mali has faced since 2012 has been the subject of many studies in the field of social sciences. Despite this, relatively little is known about non-lethal criminal violence, its evolution since the start of the crisis and how it is dealt with by the population. This article helps to bridge these gaps using data from Governance, Peace and Security (GPS) survey modules integrated into the modular and permanent household survey conducted each year since 2014. Given the unparalleled accuracy of GPS data, we are also able to establish a profile of crime victims in Mali. Despite a very high and growing sense of insecurity among the population, victimisation rates saw a steady decline in Mali up until 2019. This positive trend was brought to a halt in 2020 and set off alarm bells. Offences are rarely reported to the public authorities and we try to identify the possible reasons for this. Women, people with no formal education and members of poorer households in particular are generally less likely to be victims of crime. Residents of the regions of Mopti, Tombouctou and Gao tend to be more exposed.
Elohim or Elohayim
Authors: Suria Isak
Published: March 2023

The Hebrew language consists of a series of pictograph letters that have no vowels, all the letters are consonants, but at that time people could still read and understand them. After the Israelites were colonized for more than 1000 years by other nations, the Jews could no longer read and interpret it, especially the Tanakh (Jewish holy book), so that debates arose among one another. Then to solve this problem, in the 10th century bc Jewish scholars (called masoretes) took notice, scrutinizing every utterance said by the rabbis, when they read the Torah in the Synagogue. Then vowel signs (niqud) were made, namely qamets (a), patakh (a), tsere (e), kholem (o), qibbud (u), khireq (i), sureq (u). With the existence of niqud, everyone can read and understand what is written in God's Torah. בְּרֵאשִׁ֖ית בָּרָ֣א אֱלֹהִ֑ים אֵ֥ת הַשָּׁמַ֖יץם (Beresyit bara' 'elohim 'et hasysyamayim we'et ha'aret) all these words are given a niqud. But there is one question about the wordאלהיםshould it be read 'elohim by adding niqud e, o, i (אֱלֹהִ֑ים) or read another. Because if you pay attention to grammarHebrew, then saidאֱלֹהִ֑יםim denotes the plural, but im in Genesis 1:1 is the singular form, as opposed to elohim in Exodus 20:3. The plural Elohim are the gods (gods), while the singular 'elohim is the God of the universe. We also find the final shapean im which shows something broad like mayim, syamayim. Actually mayim, syamayim bdoesn't end in im, but ayim. So that 'elohim should not use the word 'im but elohayim, just like mayim, syamayim and so on. So one can clearly distinguish whether this is the God of the universe or the gods. There are also those who explain that im which is singular is plural qualitative while im which is plural is im quantitative.
How can we Guess the Distribution of Wealth in Greenville, Mississippi? A Proposed Heuristic for Guessing Distributions
Authors: Neuman Yair , Dayan Itzhak
Published: March 2023

How can laymen approximate a real-world distribution while being “rationally bounded”? In this paper, we show that guesstimating a real-world distribution is possible by using the “True Median”. We show that choosing the best distribution among combinatorically potential distributions through the True Median criterion is a straightforward approach for choosing the distribution that _maximizes the entropy_ and therefore the one that provides the least biased approximation of the real one. We conclude by proposing a rule of thumb that works as effectively as any of our proposed calculations.

Medan has a tropical climate and has the potential to support additional renewable energy, one of which is wind energy. Analysis of wind speed in Medan in particular has not been conducted to determine the potential for renewable energy. Research on wind speed in Medan, which ranges from 3.5m/s to 7.5m/s, has been carried out, but its potential has not been analyzed and evaluated. This study was conducted to analyze the shape factor and scale for wind speed using the Weibull and Rayleigh distribution, and three evaluation models were proposed, namely the correlation coefficient (R2), Chi-Square (ꭓ2), and Root mean square error (RMSE). Wind speed data that is used to analyze and evaluate obtained from the Meteorology, Climatology, and Geophysics Agency for a period of three years, 2017 to 2019 in Medan. The probability density distribution function (Pdf) is described based on the shape (k) and scale (c) parameters obtained from the above data analysis. These two parameters are very important to be observed related to the potential of electrical energy produced in a place or area. The analysis result shows that Weibull is better than Rayleigh distribution based on Pdf. Meanwhile statistical analysis, Weibull distribution is better than Rayleigh distribution based on R2. But on the other hand, the Rayleigh distribution is better than the Weibull distribution based on Chi-Square and RMSE. In addition to the analysis and evaluation, the potential for wind energy to be obtained is around 79.5 Watt/m2.

Published: March 2023

The relevance of the study is conditioned upon the necessity of wider implementation of sentences alternative to imprisonment. It is largely connected to the international commitments that Ukraine has made in the process of European integration. The purpose of the study is to determine the economic and psychological conditions for the functioning of the legal institution of probation. The research uses dialectical, comparative legal, systemic, Aristotelian, structural and functional methods. The research defines the concept of probation as a system of supervisory and social and educational measures for convicts who have been sentenced to a non-custodial criminal sentence. The author presents the stages of implementation of the probation institute in Ukraine and explains the essence of probation, its types and functions. The author identifies the socio-psychological advantages of such an institution and substantiates the economic feasibility of probation supervision as compared to other punishments. It is established that the introduction of this institution provides several benefits for the State, society and the offender. The author outlines the benefits for the state in terms of reducing the number of prisoners; reducing the crime rate; compliance with international standards; and economic benefits. The benefits to society are identified, which include the fair administration of justice and the protection of the community from recidivism. In addition, attention is devoted to the benefits for the offender, namely, the opportunity to change without being imprisoned, preservation of human relations, housing and work. It is substantiated that in the current circumstances, the introduction of probation supervision is a necessity conditioned upon economic expediency and the possibility of administering justice more humanely. The results of the research can be used for implementation in the area of regulation, and for writing monographs, scientific researches, dissertations, drafting abstracts, and preparing reports at scientific conferences.

Authors: YİLMAZ Onur
Published: March 2023

In recent years, the importance and use of wet-white tanning technology have increased due to the increase in environmental and health concerns. On the other hand, this technology still has problems related with fixation of dyestuff and fatliquoring agents during wet-end processes. In this study, the effect of the use of different commercial amphoteric retanning agents in different ratios on dyestuff consumption was investigated. For this purpose, amphoteric polymers were used at the beginning of dyeing process of syntan tanned leathers and the concentrations of remaining dyestuff after the process have been measured using UV-Vis Spectrophotometer for each trial. From the results it was concluded that the use of amphoteric polymers in retanning of wet-white tanned leathers significantly decreased the remaining dyestuff in the floats. Also, the physical and mechanical properties of the final leather were not adversely affected up to the use of 6 wt% the amphoteric polymer.

Temperature affects the duration of embryonic and larval periods in amphibians. Plasticity in time to metamorphosis is especially important in amphibian populations of Mediterranean semi-arid zones where temperatures are high and precipitation is low, increasing the rate of pond desiccation. In order to test the influence of water temperature on the larval development and growth of the natterjack toad (Bufo calamita), we collected two spawns in a semi¿arid zone at Balaguer (Lleida, NE Iberian peninsula). Approximately 50 (+/-10) eggs (stage 14-16) were raised in the lab at different temperature conditions: 10, 15, 20, 22.5 and 25ºC with 12:12 photoperiod. The results show a lengthening of development time with decreasing temperatures and a better survival performance of B. calamita to high temperatures. However, mean size at metamorphosis was not different across treatments, thus, suggesting that this population of B. calamita requires a minimum size to complete the metamorphosis. This study is the first approach to examine the effects that climatic factors have on the growth and development of B. calamita in semi-arid zones.
Left brachial plexopathy after prone positioning with COVID-19: a case series
Authors: Wunder Meaghan , Seslija Dana , Liem Nathania
Published: March 2023

Prone positioning is a strategy shown to reduce mortality in patients who are mechanically ventilated for acute respiratory distress syndrome and has been used in the COVID-19 pandemic. It is not, however, without complications. Barotrauma, pressure sores, ventilator associated pneumonia and peripheral nerve injuries have all been implicated as complications of prone positioning. There have also been several reports of brachial plexopathy in patients who have undergone prolonged mechanical ventilation with prone positioning. Patient characteristics including body weight index, degree of critical illness, and suboptimal prolonged positioning have all been suggested as possible contributing factors, although, there has been less discussion concerning the action of rolling patients, and how it may contribute to the development of injuries. We describe 3 cases of left brachial plexus injury in patients who were consistently rolled on their left sides. Patients presented with isolated left upper extremity weakness without any structural etiology found on imaging. Electrodiagnostic studies subsequently confirmed a left brachial plexopathy in each of the cases. We suggest that the action of proning patients may contribute to injury. This observation has not yet been suggested in the literature, and carries clinical relevance, as greater attention and meticulous care may need to be employed when moving these individuals.

Survival from extranodal nasal-type NK/T-cell lymphoma (ENKTCL) has substantially improved over the last decade. However, there is little consensus as to whether a population of patients with ENKTCL can be considered “cured” of the disease. We aimed to evaluate the statistical “cure” of ENKTCL in the modern treatment era. This retrospective multicentric study reviewed the clinical data of 1955 patients with ENKTCL treated with non-anthracycline-based chemotherapy and/or radiotherapy between 2008 and 2016 in China Lymphoma Collaborative Group multicenter database. A non-mixture cure model with incorporation of background mortality was fitted to estimate cure fractions, median survival times and cure time points. The relative survival curves attained plateau for the entire cohort and most subsets, indicating that the notion of cure was robust. The overall cure fraction was 71.9%. Median survival was 1.1 years in uncured patients. The cure time was 4.5 years, indicating that beyond this time, mortality in ENKTCL patients was statistically equivalent to that in the general population. Cure probability was associated with B symptoms, stage, performance status, lactate dehydrogenase, primary tumor invasion, and primary upper aerodigestive tract site. Elderly patients (>60 years) had similar cure fraction to that of younger patients. Five-year overall survival rate correlated well with the cure fraction across risk-stratified groups. Thus, statistical cure is possible in ENKTCL patients receiving current treatment strategies. Overall probability of cure is favorable, though it is affected by presence of risk factors. These findings have a high potential impact on clinical practice and patients’ perspective.

Warming-induced changes in reef fish community traits in the Southwestern Atlantic transition zone
Authors: Silva FC , Floeter SR , Lindegren M , Quimbayo JP
Published: March 2023

Marine communities are subject to alterations in environmental conditions, due to both natural variability and climate change. For instance, a rapid increase in sea surface temperature (SST) can modify spatial distribution patterns and abundances of reef fishes and therefore alter the overall diversity, structure, and functioning of these communities. Trait-based approaches may accurately detect community responses to such environmental changes, because species traits should reflect resource and habitat requirements. Here, we investigated temporal variability in reef fish trait composition and thermal affinity and assessed whether shifts are linked to recent ocean warming. We combined species traits related to feeding, growth, and survival with abundance data on reef fish from underwater visual census at 7 islands of the Southwestern Atlantic subtropical transition zone. All islands exhibited gradual trait reorganization from fish assemblages dominated by large-size species at the beginning of the time period to small, cryptobenthic species towards the end. The temporal changes in community weighted mean traits and the community thermal index were related to SST, indicating a numerical response of species to climatic variations. Tropical species are slowly becoming more abundant over time, while temperate species are becoming less abundant, reflecting an initial change in fish composition in this transition zone. These results have ecological implications leading communities to a faster turnover, lower food-chain complexity, and higher vulnerability to change. We highlight the importance of integrating traits and abundance time series data for a holistic understanding of reef dynamics and community responses to environmental variation, including global warming.

We perceive the family as a social institution that fulfills important social functions, which undoubtedly include an educational function. However, concerning the impact of socio-economic conditions, cultural changes as well as the impact of other cultures, the educational activities in contemporary families are changing. The study deals with the research focused on determining the educational influence of current parents. Parents from different regions of Slovakia took part in the research. The research results were processed using the descriptive statistics methods and the Student t-test was used for the purpose of comparison. Based on obtained results it may be stated that current parents are perceived as quite liberal, without setting limits and clear rules in raising their children, and with a tendency to excuse children’s mistakes. Their raising is marked by high pressure on children’s school performance while they attribute the responsibility for school results and education to school.

This article provides a review of the scientific literature over the past 30 years on the assessment of the anatomical or ‘true’ difference in leg length (structural Limb Length Discrepancy, sLLD), as well as a summary of our own clinical experience on this issue.Purpose. Carrying out a systematic analysis of publications on methods for assessing the anatomical difference in leg length and the diagnostic significance of its detection in order to provide highly effective care to patients with diseases of the musculoskeletal system.Materials and methods. The study presents a description of modern hardware and manual methods for assessing sLLD, the shortcomings of their isolated use, and substantiates the need for a comprehensive examination of patients with sLLD with a combination of manual and hardware diagnostic methods.Results and discussion. The results of observations patients with various diseases of the musculoskeletal system and comorbid neurological symptoms are presented. Examples of postural radiographs of patients with anatomical difference in leg length after arthroplasty are given; with persistent functional shortening of the limb of traumatic origin. The possibilities of differentiated correction of pain syndromes of musculoskeletal origin under the influence of an anatomically short leg on pelvic skew, scoliosis in the form of lift therapy, and the possibility of manual correction in upslip functional dysfunction are considered.Conclusions. An unrecognized and not timely compensated structural difference in the length of the legs is one of the main causes of asymmetries in posture, increased fatigue and chronic pain of the musculoskeletal system, as well as a consequence of subjectivity, insufficient reliability and accuracy of many direct methods proposed in the literature for quantifying the difference in leg size. The low threshold of clinical significance of sLLD, along with the wide prevalence of this phenomenon in the population, dictates the need for increased diagnostic alertness of specialists in order to provide effective assistance to this group of patients through the combined use of pharmacotherapy, manual techniques and adequate orthopedic correction

An Estimator for Aircraft Actuator Characteristics Using Singular Value Decomposition

Published: March 2023

This paper illustrates how a Singular Value Decomposition (SVD) and regression analyses can be used to create estimation models for aircraft actuator components by use of industrial data. The estimation models are at the end used to show how an electromechanical actuator´s weight and size will evolve with respect to output force. An essential step in the early design of aircraft is to be able to predict the weight and size of a resulting concept. This weight and size typically include contributions of main components such as wing and fuselage. Weight and size estimations at this stage can also range down to components at a sub-system level, for example, the aircraft actuators. The weight and size of an actuator depends on many parameters, and it is desirable to understand any underlying relationship to make qualified estimations of an actuator’s characteristics. However, the knowledge about a design is often limited at an early design stage and the required information is not always available. Consequently, estimations must be made from limited information and desired properties of the actuator. One way to approach this problem is to use SVD. An SVD analysis determines the most influential parameters in a data set and uses these to create an estimation model that only requires a few inputs for estimating the remaining parameters in the data set. An SVD can thereby be used for both identifying the driving parameters in a statistical dataset of existing solutions and to estimate the characteristics of new designs to be developed.

Published: March 2023

Hydraulically powered flight control systems are widely used in aviation, especially for commercial aircraft, which require significant forces from system actuators to control the applicable surfaces as demanded. These systems are being studied and are evolving to become smaller, lighter, and more efficient. These improvements bring several advantages, such as payload increase and drag reduction. However, as these systems are optimized, and their dimensions are reduced, the thermal effects of fluid flow become more relevant. Especially when the working fluid passes through small orifices, excessive heat can eventually compromise the equipment's performance and damage its internal subcomponents. When we analyze the damped mode operation of actuation systems presented on some commercial aircraft, these restrictions become even more relevant – knowing that the damping orifice diameter can be significantly reduced to provide the desired performance for the operation. Therefore, the main goal of this study is to analyze and evaluate the thermal impact on an Electro-Hydraulic Servo Actuator (EHSA) while in damped mode operation, contributing to the industry and the literature in this kind of assessment. Through the research presented, it's possible to estimate the temperature of the system's components and, consequently, avoid malfunctions caused by overheating. Furthermore, developing a model allows the simulation of various environmental conditions, reducing rig costs or in-flight tests. The modeling approach was conducted on the MATLAB/Simulink platform. It was based on two main points that improved model comprehension during its development and minimized errors: the building blocks philosophy of segregating each component's influence and model, and the continuous validation of the model through a comparison with a physics-integrated software (AMESim).

The current transition towards the circular bioeconomy requires a rational development of biorefineries to sustainably fulfill the present demands. The use of Komagataella phaffii (Pichia pastoris) can meet this challenge, since it has the capability to use crude glycerol as a carbon-source, a by-product from the biodiesel industry, while producing high- and low-added value products. Recombinant protein production (RPP) using K. phaffii has often been driven either by the methanol induced AOX1 promoter (PAOX1) and/or the constitutive GAP promoter (PGAP). In the last years, strong efforts have been focused on developing novel expression systems that expand the toolbox variety of K. phaffii to efficiently produce diverse proteins that requires different strategies. In this work, a study was conducted towards the development of methanol-free expression system based on a heat-shock gene promoter (PDH) using glycerol as sole carbon source. Using this promoter, the recombinant expression is strongly induced in carbon-starving conditions. The classical PGAP was used as a benchmark, taking for both strains the lipase B from Candida antarctica (CalB) as model protein. Titer of CalB expressed under PDH outperformed PGAP controlled expression in shake-flask cultivations when using a slow-release continuous feeding technology, confirming that PDH is induced under pseudo-starving conditions. This increase was also confirmed in fed-batch cultivations. Several optimization rounds were carried out for PDH under different feeding and osmolarity conditions. In all of them the PDH controlled process outperformed the PGAP one in regard to CalB titer. The best PDH approach reached 3.6-fold more specific productivity than PGAP fed-batch at low μ. Compared to the optimum approach for PGAP-based process, the best PDH fed-batch strategy resulted in 2.3-fold higher titer, while the specific productivity was very similar. To summarize, PDH is an inducible promoter that exhibited a non-coupled growth regulation showing high performance, which provides a methanol-free additional solution to the usual growth-coupled systems for RPP. Thus, this novel system emerges as a potential alternative for K. phaffii RPP bioprocess and for revaluing crude glycerol, promoting the transition towards a circular economy.
