Sensor-Arrays mit Metalloxid- Gassensoren zur Gaserkennung und Konzentrationsbestimmung in Echtzeit

Der Beitrag stellt eine Methode zur Gasanalyse in Echtzeit mittels Sensor-Arrays, die nichtlineare Sensorelemente enthalten, vor. Sie beruht auf einem nichtlinearen dynamischen Modell, das neben der Konzentration reduzierend wirkender Gase auch den Absolutdruck p(t) aufnimmt. Die Verarbeitung der Sensorsignale erfolgt in drei Stufen. Nach Kompensation der Sensordynamik durch ein nichtlineares Filter detektiert ein neuronales Netzwerk reduzierend wirkende Gase, deren Konzentrationen anschließend bestimmt werden. Zukünftig enthält das Leckageerkennungsund Ortungssystem LEOS das entwickelte Verfahren. Die Verfikation des Verfahrens bezieht sich auf Messungen von definierten Konzentrationsverläufen verschiedener Gase, die ebenfalls die Sensorkalibrierung heranzieht. Die Ergebnisse zeigen, daß neuronale Netzwerke eindeutig reduzierend wirkende Gase (Aliphate, Ketone, Alkohole, chlorierte Kohlenwasserstoffe, Benzol, NH3 und Η2) klassifizieren und sich der Konzentrationsverlauf genau rekonstruieren läßt.
Optimisasi Carbopol Sebagai Basis Gel pada Gel Antiseptik Berbasis Alkohol

Alcohol-based antiseptic gels are considered to be able to replace washing hands with soap and can inhibit the growth of viruses. Alcohol-based gels have the disadvantage of being difficult to mix with gel-based ingredients. Carbopol as an alcohol-soluble gel base was chosen to be the base for this alcohol-based antiseptic gel. The concentrations used were 0.5%, 0.75%, 1%, 1.25%, 1.5%, 1.75%, and 2%. The physical test of the gel was carried out to see the optimum carbopol gel base for alcohol-based antiseptic gel. Physical test includes organoleptic observation, pH value, viscosity determination spreadability test and homogeneity test. The results obtained from organoleptic observation showed that the gel was clear, smelled antiseptic, two concentrations had a slightly sticky and sticky consistency. The pH value yields a pH range of 4.65 - 6.06. The viscosity results showed a viscosity range of 10.48725 - 21.18107 Pa.S. The Spreadability test shows the spreadability range of 6.07 - 7.03 cm. The homogeneity test resulted in an alcohol-based antiseptic gel without coarse particles. Hedonic organoleptic test produced the most preferred antiseptic gel was the antiseptic gel with a carbopol concentration of 1.25%. The results showed that the optimal carbopol was used as a gel base in an alcohol-based antiseptic gel 1.25% carbopol.
Vaccination against Tick-Borne Encephalitis (TBE) in Italy: Still a Long Way to Go

Tick-borne encephalitis (TBE) is endemic in several European countries, and its incidence has recently increased. Various factors may explain this phenomenon: social factors (changes in human behavior, duration and type of leisure activities and increased tourism in European high-risk areas), ecological factors (e.g., effects of climate change on the tick population and reservoir animals), and technological factors (improved diagnostics, increased medical awareness). Furthermore, the real burden of TBE is not completely known, as the performance of surveillance systems is suboptimal and cases of disease are under-reported in several areas. Given the potentially severe clinical course of the disease, the absence of any antiviral therapy, and the impossibility of interrupting the transmission of the virus in nature, vaccination is the mainstay of prevention and control. TBE vaccines are effective (protective effect of approximately 95% after completion of the basic vaccination—three doses) and well tolerated. However, their uptake in endemic areas is suboptimal. In the main endemic countries where vaccination is included in the national/regional immunization program (with reimbursed vaccination programs), this decision was driven by a cost-effectiveness assessment (CEA), which is a helpful tool in the decision-making process. All CEA studies conducted have demonstrated the cost-effectiveness of TBE vaccination. Unfortunately, CEA is still lacking in many endemic countries, including Italy. In the future, it will be necessary to fill this gap in order to introduce an effective vaccination strategy in endemic areas. Finally, raising awareness of TBE, its consequences and the benefit of vaccination is critical in order to increase vaccination coverage and reduce the burden of the disease.
Electromagnetic Modelling Of Foetus AndPregnant Woman Exposed To Extremely LowFrequency Electromagnetic Fields

The paper presents a three dimensional BEM model of a pregnant woman and foetus exposed to extremely low frequency electromagnetic fields. In particular, the case scenario solved is focused on the case of exposure to high voltage power transmission lines. The paper presents the corresponding theory, BEM computational implementation, and results. The latter are expressed in terms of current density, potential and electric field in the different tissues. This work is part of an ongoing research whose overall objectives are to provide accurate estimations of fields and induced currents for assessing exposure of human bodies to electro-magnetic fields.
The Relationship Between Default Mode and Dorsal Attention Networks Is Associated With Depressive Disorder Diagnosis and the Strength of Memory Representations Acquired Prior to the Resting State Scan

Previous research indicates that individuals with depressive disorders (DD) have aberrant resting state functional connectivity and may experience memory dysfunction. While resting state functional connectivity may be affected by experiences preceding the resting state scan, little is known about this relationship in individuals with DD. Our study examined this question in the context of object memory. 52 individuals with DD and 45 healthy controls (HC) completed clinical interviews, and a memory encoding task followed by a forced-choice recognition test. A 5-min resting state fMRI scan was administered immediately after the forced-choice task. Resting state networks were identified using group Independent Component Analysis across all participants. A network modeling analysis conducted on 22 networks using FSLNets examined the interaction effect of diagnostic status and memory accuracy on the between-network connectivity. We found that this interaction significantly affected the relationship between the network comprised of the medial prefrontal cortex, posterior cingulate cortex, and hippocampal formation and the network comprised of the inferior temporal, parietal, and prefrontal cortices. A stronger positive correlation between these two networks was observed in individuals with DD who showed higher memory accuracy, while a stronger negative correlation (i.e., anticorrelation) was observed in individuals with DD who showed lower memory accuracy prior to resting state. No such effect was observed for HC. The former network cross-correlated with the default mode network (DMN), and the latter cross-correlated with the dorsal attention network (DAN). Considering that the DMN and DAN typically anticorrelate, we hypothesize that our findings indicate aberrant reactivation and consolidation processes that occur after the task is completed. Such aberrant processes may lead to continuous “replay” of previously learned, but currently irrelevant, information and underlie rumination in depression.
Assessing Government Involvement in the Balkan Countries’ Economies

The extent to which the government intervene the marketplace and the government’s role in the economy is an important factor, determin­ing the economic results achieved by a country. In the academic literature, the question of whether the promotion of this participation contributes to an im­provement of the development of a nation or, on the contrary, can contribute to a loss of competitive advantages, is debatable. This study focuses on the degree of involvement of national governments in the economies of the Bal­kan region countries. For the purpose of analysis, a cluster analysis is applied, through which the Balkan countries are divided into several groups (clusters), characterized by different degrees of government participation. Three peri­ods are considered - before and in the first years of the global economic and fi­nancial crisis, as well as just before the current COVID-19 pandemic. The anal­ysis is supplemented by an assessment of the impact of individual clusters on the economic development of these countries.
Ein Entwurfsverfahren für parameterunempfindliche Abtastregelungen / A design procedure for parameter insensitive sampled data control

Es wird ein Regelalgorithmus für lineare steuerbare und beobachtbare Verzögerungsstrecken n-ter Ordnung angegeben, mit dem, je nach der Anzahl der Streckenausgänge, die Empfindlichkeitsfunktionen der Ausgangsgröße bezüglich Änderungen von maximal η Streckenparametern unabhängig voneinander nach dem „dead-beat"-Kriterium zu einem Minimum gemacht werden können. Dadurch wird erreicht, daß die Abweichung des Systemzustands von seinem Nominalwert ebenfalls nach dem „dead-beat"-Kriterium minimal ist, unabhängig davon, oh ein oder mehrere Streckenparameter von den nominalen Werten abweichen.
Beyond facial width-to-height ratios: bizygomatic width is highly sexually dimorphic when adjusting for allometry

A large and ever-growing literature implicates male facial width-to-height ratio (bizygomatic width divided by facial height) as a secondary sexual trait linked to numerous physical and psychological perceptions. However, this research is based entirely on the premise that bizygomatic width is sexually dimorphic, which recent research has called into question. Unfortunately, statisticians for the last 125 years have noted that morphological ratio measurements may engender spurious correlations and biased effect-size estimates. In the current study, we find that bizygomatic width is highly sexually dimorphic (equivalent d = 1.39), even after adjusting for 92 allometric measurements, including multiple facial height and other craniofacial measurements (equivalent d = 1.07) in a sample of 6068 men and women. By contrast, facial width-to-height ratio (fWHR) measurements demonstrated a statistical pattern consistent with the age-old argument that morphological ratio measurements may engender spurious correlations and biased effect-size estimates. Thus, when avoiding facial ratio measurements and adjusting for allometry in craniofacial measures, we found strong support for a key premise in the human evolutionary and behavioural sciences that bizygomatic width exhibits male-biased sexual dimorphism.
Estimating Time-averaged Turbulent FluidForces From An Ensemble-averaged FlowField For Engineering Applications

Solid structures are subjected to mechanical forces imposed upon them by a moving fluid. If the flow is turbulent, the mechanical forces would fluctuate randomly with time. For engineering applications, the statistical approach is normally preferred whenever turbulent flows are encountered. As a consequence, the measured or numerically computed flow fields are ensemble-averaged. The objective of this investigation is to develop an engineering methodology to estimate these mechanical forces from the ensemble-averaged flow field. Special attention would be paid to those forces that contribute to mechanical vibrations of the solid structures. In our study of airflow induced vibrations on the working parts of computer hard disk drives, the turbulent flow fields of an actual 2.5-inch computer hard drive had been measured in-situ. From the ensemble-averaged flow field, various types of mechanical forces like pressure, shear (drag) forces and vortex (lift) forces could be obtained. By neglecting the constant forces, we focused our attention on the ensemble averaged fluctuating velocity-vorticity interactions. The consequence of the interaction is the production of ensemble-averaged fluctuating vortex forces that act on the actuator. The fluctuating components of vortex forces can be calculated from the gradients of Reynolds shear stresses measured directly from the flow field experimentally. The magnitudes of fluctuating vortex forces increases dramatically with the disk rotational speed, which matches the behaviour of positional error signals (PES) measured in-situ from an actual operating hard disk drive. The corresponding increase in PES and fluctuating vortex forces with disk rotational speed suggested that flow induced vibration in the hard disk drive may be due to an increase in flow turbulence in the hard disk drive. Some suggestion on flow turbulence identification and attenuation are discussed.
Modellbasierte Prozeßüberwachung am Beispiel eines Gasverdichters / Model-based Condition Monitoring by the Example of a Gas Compressor

Bei der konventionellen Überwachung industrieller Prozesse ist es üblich, jede der gemessenen Prozeßvariablen auf die Verletzung fest eingestellter Alarmgrenzwerte zu überprüfen. Damit die bei Betriebspunktänderungen schwankenden Prozeßgrößen keinen Fehlalarm auslösen, müssen die Alarmgrenzwerte sehr konservativ eingestellt werden; kleine Fehler im Prozeßverhalten können somit nicht detektiert werden! Hier wird eine Methode vorgestellt, welche es erlaubt, auch kleinste Prozeßfehler zu detektieren und zu lokalisieren. Die vorgestellte Methode verwendet ein mathematisches Modell des zu übenwachenden Prozesses, welches sehr einfach aus einem Meßdatensatz der Prozeßvariablen gewonnen werden kann. Nach einer theoretischen Einführung in die Grundlagen der modellbasierten Prozeßüberwachung wird am Beispiel eines Gasverdichters sowohl auf die Modellbildung als auch auf die Fehlerdetektion und die Fehleranalyse eingegangen.
Future Time Perspective and Its Influence on Life Satisfaction through Hope

Life satisfaction refers to one’s assessment of life in general. Low life satisfaction leads to negative impacts to a person’s mental health condition. This study identified and analyzed the relationship between the future time perspective and life satisfaction through hope in 567 state high school students in Semarang City. Data were collected using the Satisfaction With Life Scale (SWLS), Synder Hope Scale (SHS) and Future Time Perspective Scale (FTPS). The results of the analysis showed that hope fully mediated the relationship between future time perspective and students’ life satisfaction. This study found that students with good future perspective were satisfied with life because they were able to make route in achieving their goals. The results of this study can be used as insights in counseling intervention and for further research.
The Relationship of Sleep Deprivation with the Poor Academic Performance and Adolescents’ Mental Health

Adolescent mental health problems have a proportion of up to 16% of the total burden of disease for people aged 10-19 years in the world. Various studies suggest that lack of sleep in adolescents can affect poor academic performance and the emergence of mental health problems such as depression. This article is intended to review the relationship between lack of sleep in adolescents with poor academic performance and the emergence of mental issues from a neuroscience perspective. We conducted a literature review regarding sleep deprivation and physiological phenomena that occur in the adolescent brain, which is then associated with mental health problems and decreased academic performance. At the end, we propose several solutions that can be used as policy guidelines to improve adolescent academic performance and maintain adolescent mental health.
Does the Pachytene Checkpoint, a Feature of Meiosis, Filter Out Mistakes in Double-Strand DNA Break Repair and as a side-Effect Strongly Promote Adaptive Speciation?

Synopsis This essay aims to explain two biological puzzles: why eukaryotic transcription units are composed of short segments of coding DNA interspersed with long stretches of non-coding (intron) DNA, and the near ubiquity of sexual reproduction. As is well known, alternative splicing of its coding sequences enables one transcription unit to produce multiple variants of each encoded protein. Additionally, padding transcription units with non-coding DNA (often many thousands of base pairs long) provides a readily evolvable way to set how soon in a cell cycle the various mRNAs will begin being expressed and the total amount of mRNA that each transcription unit can make during a cell cycle. This regulation complements control via the transcriptional promoter and facilitates the creation of complex eukaryotic cell types, tissues, and organisms. However, it also makes eukaryotes exceedingly vulnerable to double-strand DNA breaks, which end-joining break repair pathways can repair incorrectly. Transcription units cover such a large fraction of the genome that any mis-repair producing a reorganized chromosome has a high probability of destroying a gene. During meiosis, the synaptonemal complex aligns homologous chromosome pairs and the pachytene checkpoint detects, selectively arrests, and in many organisms actively destroys gamete-producing cells with chromosomes that cannot adequately synapse; this creates a filter favoring transmission to the next generation of chromosomes that retain the parental organization, while selectively culling those with interrupted transcription units. This same meiotic checkpoint, reacting to accidental chromosomal reorganizations inflicted by error-prone break repair, can, as a side effect, provide a mechanism for the formation of new species in sympatry. It has been a long-standing puzzle how something as seemingly maladaptive as hybrid sterility between such new species can arise. I suggest that this paradox is resolved by understanding the adaptive importance of the pachytene checkpoint, as outlined above.

It continues with a description of the current situation of the tourism industry and outlines the value of stakeholder theory in the recovery of the tourism sector. It is affirmed that the principles of instrumental stakeholder theory are capable of creating competitive advantage and social welfare. In order to attain both, stakeholder work needs to be performed and stakeholder engagement needs to be undertaken. It is argued that instrumental stakeholder theory might be very helpful for the sustainable recovery of the tourism sector after the pandemic.
The impact of unemployment insurance on reinsertion wages in 2015 in the rural environment of Brazil

Abstract: This work sought to provide new evidence on the impact of the Brazilian Unemployment Insurance Program (Programa Seguro-Desemprego) on the reinsertion wages of its beneficiaries, considering the Brazilian rural environment. Datafrom the National Household Sample Survey (Pesquisa Nacional por Amostra de Domicílios- PNAD) of 2015 was used, as well as the Sharp model discontinuity regression method. The results showed a positive effect on the reinsertion wages of individuals who participated in the Unemployment Insurance Program in rural Brazil. When disaggregating by Brazilian regions, the Southeast region had a greater positive effect on reinsertion wages, while the Midwest region has a negative effect on workers who participated in the Unemployment Insurance Program. Among the main conclusions, it is a fact that the Unemployment Insurance program had a positive effect for Brazilian formal rural workers residing in the Southeast of the country, but a negative effect for those residing in the Center-West region of Brazil.
