Objectives

Red blood cell parameters are frequently used biomarkers when assessing clinical status in newborns and in early childhood. Cell counts, amounts, and concentrations of these parameters change through gestation and after birth. Robust age-specific reference intervals are needed to optimize clinical decision making.

Methods

The Copenhagen Baby Heart Study (CBHS) and the COMPARE study are prospective cohort studies including red blood cell parameters from 7,938 umbilical cord blood samples and 295 parallel venous blood samples from newborns with follow-up at two and at 14–16 months after birth.

Results

For venous blood at birth, reference intervals for hemoglobin, erythrocytes, and hematocrit were 145–224 g/L, 4.1–6.4 × 1012/L, and 0.44–0.64, respectively. Hemoglobin, erythrocytes, and hematocrit were lower at birth in children delivered by prelabor cesarean section compared to vaginal delivery. Conversion algorithms based on term newborns were: venous hemoglobin=(umbilical cord hemoglobin˗86.4)/0.39; venous erythrocytes=(umbilical cord erythrocytes-2.20)/0.44; and venous hematocrit=(umbilical cord hematocrit-0.24)/0.45.

Conclusions

This study presents new reference intervals for red blood cell parameters in early childhood, describes the impact of delivery mode, and provide exact functions for converting umbilical cord to venous blood measurements for term newborns. These findings may improve clinical decision making within neonatology and infancy and enhance our clinical understanding of red blood cell parameters for health and diseases in early life.
Imagining the future of diagnostic performance feedback
Authors: Rosner Benjamin I. , Zwaan Laura , Olson Andrew P.J.
Published: November 2022

Diagnostic performance is uniquely challenging to measure, and providing feedback on diagnostic performance to catalyze diagnostic recalibration remains the exception to the rule in healthcare. Diagnostic accuracy, timeliness, and explanation to the patient are essential dimensions of diagnostic performance that each intersect with a variety of technical, contextual, cultural, and policy barriers. Setting aside assumptions about current constraints, we explore the future of diagnostic performance feedback by describing the “minimum viable products” and the “ideal state” solutions that can be envisioned for each of several important barriers. Only through deliberate and iterative approaches to breaking down these barriers can we improve recalibration and continuously drive the healthcare ecosystem towards diagnostic excellence.

Authors: Rachamala Ravi Kumar , Sanke Narasimhulu , Seshu Kumar A.
Published: November 2022

Producing sustainable energy to meet the world’s current demands is a major concern. Municipal Solid Waste (MSW) is a good source for producing sustainable energy and currently gets abundantly generated in India. Usually MSW is screened to prepare Segregated Dry Municipal Solid Waste (SDMSW) pellets before subjecting it to gasification to produce producer gas. But, generation of hazardous byproducts is a key issue in the conversion of SDMSW to producer gas. In the present work a multi-purpose downdraft gasifier has been designed and developed that can process biomass and SDMSW pellets blend while reducing undesirable byproducts such as tar and ash. The calorific value, chemical composition and byproduct content of the SDMSW pallets blended with biomass are determined prior to gasification. The feedstock is characterised using ultimate and proximate analysis, and the calorific value is determined using a bomb calorimeter. Gas chromatography is used to assess the quality of the producer gas. The results indicate that adding 50% SDMSW to Biomass results in good efficiency.
The Death of Law
Authors: Mattei Ugo
Published: November 2022

This is a talk about the decline and fall of constitutional law, an overarching characteristic of the new millennium. I focus on the period from the end of the Cold War—once described as the end of history—to what I call the “Second Cold War” beginning in the second decade of this century and having escalated in the proxy war in Ukraine. The Second Cold War is also characterized by an aborted cooptation of China through the World Trade Organization (to tame China’s seemingly unstoppable ascension to global supremacy) as well as a state of permanent emergency.

Published: November 2022

Physical well-being depends essentially on how the own body is perceived. A missing correspondence between the perception of one’s own body and reality can be distressing and eventually lead to mental illness. The touch of the own body is a multi-sensory experience to strengthen the feeling of the own body. We have developed an interaction technique that allows the self-touch of the own body in an immersive environment to support therapy procedures. Through additional visual feedback, we want to strengthen the feeling for the own body to achieve a sustainable effect in the own body perception. We conducted an expert evaluation to analyse the potential impact of our application and to localize and fix possible usability problems. The experts noted the ease of understanding and suitability of the interaction technique for increasing body awareness. However, the technical challenges such as stable and accurate body tracking were also mentioned. In addition, new ideas were given that would further support body awareness.
Design and implement a mobile-based system to teach traffic signs to illiterate people
Authors: Alfayez Zainab Hameed
Published: November 2022

Nowadays, most information and communication technologies target literate users and neglect the 800 million illiterate individuals around the world. Although there have been several attempts to develop systems that help illiterate people and try to reduce the digital gap between them and those who are literate, it is still challenging to find accessible systems for illiterate people. This research aims to reduce the digital gap between illiterate and literate people in Iraq through developing a mobile application for learning traffic signs. Firstly, a requirement elicitation study was conducted to explore a set of design considerations and build an accessible interface for illiterate people. The study resulted in several design principles, such as using voice instructions, focusing on graphic content, and using the local language. Then, the mobile application was developed based on these design principles. Finally, an evaluation study was conducted to measure the usability of the developed application. The results revealed that the built application is efficient and effective, and the users were extremely satisfied in several aspects, such as easy usage and learnability, and declared that they would use it in the future and recommend it to others.
[Lys5,MeLeu9,Nle10]-NKA(4–10) induces neurokinin 2 receptor mediated urination and defecation and neurokinin 1 receptor mediated flushing in rats: measured using the rapid detection voiding assay
Authors: Cook Jason B. , Piatt Raymond , Marson Lesley
Published: November 2022

Objectives

Neurokinin 2 receptor (NK2R) agonists may be useful for treating bladder and bowel dysfunction via direct contraction of detrusor and gastrointestinal smooth muscle. The NK2R agonist [Lys5, MeLeu9, Nle10]-NKA(4–10) (LMN-NKA) induces urination and defecation, but also produces the potential side effect of dermal flushing in rats. Although LMN-NKA is a NK2R agonist, it also has affinity for neurokinin 1 receptors (NK1R). Therefore, the goal of this study was to determine the neurokinin receptor (NKR) subtypes responsible for LMN-NKA-induced urination, defecation, and flushing by blocking either NK2Rs or NK1Rs before LMN-NKA administration.

Methods

To accomplish this goal, we developed a simple high-throughput ‘rapid detection voiding assay’ to detect rapid-onset drug-induced urination and defecation in rats. In LMN-NKA dose-response experiments, LMN-NKA (10–100 μg/kg, subcutaneous) was injected and urination, defecation, and flushing were monitored for 30 min. For NKR antagonist experiments, vehicle, the NK2R antagonist GR159897, or the NK1R antagonist CP-99,994 were injected before an acclimation period. Following acclimation, saline or 100 μg/kg LMN-NKA were injected, and behavior was observed for 30 min.

Results

LMN-NKA produced dose-related increases in urination, defecation, and flushing. Blocking NK2Rs reduced urination and blocked defecation, without affecting flushing. Blocking NK1Rs did not change LMN-NKA-induced urination or defecation but reduced LMN-NKA-induced flushing.

Conclusions

Using the rapid detection voiding assay we show that LMN-NKA-induced urination and defecation are mediated by NK2Rs, while flushing is mediated by NK1Rs. Therefore, drugs that are more selective for NK2 vs. NK1Rs should produce rapid-onset urination and defecation without producing the potential side effect of flushing.

Published: November 2022

As an exceptional nonlinear material, graphene offers versatile appealing properties, such as electro-optic tunability and high electromagnetic field confinement in the terahertz regime, spurring advance in ultrashort pulse formation, photodetectors and plasmonic emission. However, limited by atomic thickness, weak light–matter interaction still limits the development of integrated optical devices based on graphene. Here, an exquisitely designed meta-cavities combined with patterned graphene is used to overcome this challenge and promote THz-graphene interaction via terahertz location oscillation. By using an 800 nm pump laser, the local field-induced strong interaction allows sensitive responses to the ultrafast energy transfer from the ultrafast optical pump to graphene electron heat, enabling 46.2% enhancement of terahertz transparency. Such optical modulation of terahertz waves shows ultrafast response in delay less than 10 ps. Moreover, thanks to the nature of graphene, the device shows unique potential for electrically dynamic tuning and further bandwidth broadening.

Published: November 2022

Cortical reactivation and regain of interareal functional connections have been linked to the recovery of hand grasping behavior after loss of sensory inputs in primates. We investigated contributions of neurons in two hierarchically organized somatosensory areas, 3b and S2, by characterizing local field potential (LFP) and multiunit spiking activity in five states (rest, stimulus-on, sustained, stimulus-off, and induced) and interareal communication after grasping behavior of dorsal column lesioned male squirrel monkeys had mostly recovered. Compared with normal cortex, fMRI, LFP, and spiking response magnitudes to step indentations were significantly weaker. The sustained component of the spiking recovered much better than the stimulus-off response. Correlation between overall spiking and γ LFP remained strong within each recovered areas 3b and S2. The interareal correlations of γ LFP were severely disrupted, except in the resting and stimulus-on periods. Interareal correlation of spiking was disrupted in the stimulus-off period only. In summary, submodality of low threshold mechanoreceptive neurons recovered differentially in input-deprived area 3b and S2 when impaired global hand grasping behavior returned. Slow-adapting-like neurons recovered, whereas rapid-adapting-like neurons did not. Interareal communications were also severely compromised. We propose that slow-adapting-like neurons and afferents in recovered area 3b and S2 mediate recovery of impaired grasping behavior after dorsal column tract lesion.

SIGNIFICANCE STATEMENTSensory feedback is essential for execution of hand grasping behavior in primates. Reactivations of somatosensory cortices have been attributed to recovery of such behavior after loss of sensory inputs via largely unknown mechanisms. In input-deprived area 3b and S2 cortex, after hand grasping behavior mostly recovered, we found slow-adapting-like neurons were greatly recovered, whereas rapid-adapting-like neurons did not. Communications between area 3b and S2 neurons were severely compromised. We suggest that recovery of slow-adapting-like neurons in input-deprived area 3b and S2 may mediate the recovery of hand grasping behavior.

Effects of straw return on soil nitrogen leaching
Authors: Zhou Benjun , Jiao Chaoxing
Published: November 2022

Nitrogen (N) is a major limiting factor for improvement in grain production. The return of straw to the soil (straw return) is regarded as a very effective option to develop sustainable agriculture. Soil N content could be increased by the straw return because straw itself contains some nitrogen. However, whether N retention could be increased by the straw return is worthy of further study. In the present study, a laboratory simulative incubation experiment was conducted to study the effects of straw addition on N leaching from soil. The experimental results showed that the pH values in soil with time were changed slightly with different straw application, there was no notable change in relative abundance of microbial taxa of different straw application in soil at domain level, and the EC of the soil did not show any clear trends after straw incorporation. The highest EC in the soil was 0.18 ds/m occurred with straw addition of 0.3%. Moreover, the N leaching amounts from soil with different straw application were decreased over time, the higher the amount of straw added in soil, the greater content of N leaching from the soil.

Published: November 2022

Psychological capital is an essential factor that influences teachers’ productivity, commitment, and overall performance. The study determined the psychological capital, emotional labor, and stress index of public-school teachers in Tubigon Districts. It is a descriptive-correlational study using standardized survey tools as data gathering tools. Three hundred fifty (350) participants were chosen through a random sampling technique from Tubigon East and West Districts, Division of Bohol, as of the schoolyear 2020 – 2021. It utilized standardized tools, namely: the Psychological Captial Questionnaire (PCQ-24) by Luthans, Avolio, Avey, and Norman (2007), the Emotional Labor of Teacher Scale (TELTS) by Brown (2011), and the Wilson Stress Profile for Teachers (WSPT) by Rosenberg (2010). Results revealed that respondents’ age, sex, religious affiliation, and years of service are related to psychological capital. The civil status and highest educational status are not statistically connected with psychological capital. Furthermore, only sex and education have a significant relationship with emotional labor. Moreover, the teacher respondents’ profile, such as religious affiliation and highest educational status, has a significant association with stress level. Conversely, age, sex, civil status, and years of service said otherwise. The results also revealed that psychological capital has a significant relationship with emotional labor and stress index. Emotional labor did not influence stress levels. When aggregated based on sex, their psychological capital and emotional labor differ; however, no significant difference in terms of stress index.

Authors: Alpuerto Maribeth Dusal , Sales Elijah Lungay
Published: November 2022

The Asian Psychological Services and Assessment, Inc. (APSA) is an institution conducting a diagnostic test of core subjects that includes Mathematics. Taking into account the importance of the subject, the researchers conducted a study on students’ performance in Math. The study sought to find if the mathematics grade is a correlator of APSA rating by testing the relationship between the final grade and APSA diagnostic test results. The researchers employed the quantitative method using documentary analysis of the existing records as to academic performance and APSA results. The subjects of the study were the 587 students of the University of Bohol High School across the four grade levels. The data obtained were then subjected to statistical treatments using the coefficient of correlation, t-test, and analysis of variance. Results revealed that there was a significant correlation between the grades and APSA results in Mathematics, while APSA results in the four levels varied significantly. This means that students with low final grades in math are likely to obtain low performance in APSA. The variance in the APSA results among the four levels implied that the trend differs - distributions of proficiency were different in the four levels.

Authors: Cuevas Ma. Melzara , Berou Mark
Published: November 2022

Mathematical aptitude reflected in academic performance is known to be based upon the attitudes of students in approaching the subject. This study aimed to determine how mathematics self-efficacy and anxiety affect academic performance. The researchers used the descriptive-normative survey and documentary analysis of existing records with the stakeholders, the Grade 7 students. Data were analyzed using the Pearson Product-Moment Coefficient of Correlation, t-test, and Chi-Square. Results showed that students had an average level of mathematics self-efficacy regarding understanding and applying the concepts of the subject. However, they also had high anxiety when working with Mathematics tasks or less confidence in achieving high marks or grades. The study concluded that the higher the students’ level of Mathematics self-efficacy, the lower their level of Mathematics anxiety. Conversely, the higher the students’ level of self-efficacy and the lower their mathematical anxiety, the higher their academic performance. It implied that education programs addressing the enhancement of Mathematics self-efficacy and reducing Mathematics anxiety among students would not only reshape their perception of the subject’s difficulty but also improve their academic performance as they move up to the secondary level.

Authors: Arcay Jr Narito M. , Calope Rose Marie L. , Libot Buenaventurada D.
Published: November 2022

Parenting styles provide the emotional climate for interaction between parents and children and have a significant impact on the family’s quality of life.   School performance is considered as the adolescents’ capacity to interact effectively with the school environment by getting the general point average of their grades in the four quarters of School Year 2018-2019.  This paper examined the effects of parenting styles on self-esteem and school performance among the Senior High students of Tubigon, Bohol, Philippines. The study utilized the descriptive normative survey method of research in gathering data through the use of a standardized survey tool in getting the parenting styles and self-esteem of the respondents. Data mining or desk review was conducted in securing the academic performance of the Senior High School of Tubigon, Bohol. Data were processed using averaging, Freeman Halton Test, Kruskal-Wallis test, and Chi-Square. The majority of the 400 respondents yielded similar results in the four parenting styles, first is authoritative in both mothers (52.5 percent) and fathers (46.5 percent). It is followed by the permissive, father (21.5 percent), and mother (17.8 percent). It is followed by ambivalent parenting with fathers (18.8 percent) and mothers (17 percent). The majority (75.5 percent) of the respondents have high self-esteem. Almost a fourth (24.5 percent) had average self-esteem, and no one reflected low self-esteem. Nearly half (45.8 percent) of the total number of respondents had satisfactory school performance, more than a third (36 percent) had an outstanding rating, above a tenth (14 percent) had Very Satisfactory, and very few reflected Fairly Satisfactory (4.3 percent) results. The result of the Freeman-Halton test revealed that there is no statistically significant association between the fathers’ and mothers’ parenting styles and the age groups of the respondents. The Chi-square test revealed that the parenting styles of both the father (X2=7.717, df=3, p<0.10) and the mother (X2 =7.683, df=3, p<0.05) are statistically associated with the sex of the respondents. As to the relationship between self-esteem and academic performance, chi-square revealed a significant result. There is strong evidence of a difference (p-value < 0.05) between the mean ranks of at least one pair of the indicated categories. There is strong evidence that suggests that parenting styles have some bearing on how students perform at school.

The questionnaire on Financial Literacy and Management Practices was used to measure the financial literacy of individuals. The questionnaire considered the most critical personal finance factors in the measurement of the level of financial knowledge literacy and the financial decision-making on financial practices (Cronbach’s Alpha results of Financial Literacy of 0.929, Financial Management of 0.738). It was found that the Normality Test utilizing the Shapiro-Wilk yielded significant results in almost all items. Hence, non-parametric tests were used in the statistical runs. To ensure the “do-no-harm,” after complying with the consenting forms, the researchers submitted them to the Ethics Review Committee as an assurance that the researchers followed the ethics protocol. Financial Literacy and Management Practices significantly differ in each of the three groups in the congregation namely Leaders (t=11.567, exact sig=0.000), Non-Leaders between financial literacy and management practices by rank in the congregation (t=12.431, exact sig=0.000), and Members (t=23.930, exact sig=0.000). T-Test showed significant differences between the financial management practice on Personal/Family Budget and Financial Decision-Making.

The designs of band-pass filters on multilayer dielectric structures consisting of half-wave resonators exclusively, as well as with quarterwave resonators at the edges of the considered structures are investigated. The principles of constructing devices with specified characteristics are described and the basic laws of the behavior of frequency-selective properties of multilayer structures on their design parameters are explained. It is shown for the first time that in multilayer bandpass filters on one-dimensional dielectric structures, the frequency responses remain unchanged when the steps of the characteristic impedance between adjacent layers of the structure are inverted. The boundaries of the realized characteristics of filters are determined using the existing set of modern materials widely used in radio engineering (1 ≤ ε ≤ 1000). It was found that the achievable values of relative passband in constructions consisting exclusively of half-wave layers ranged from 21% to 93%, while the most narrow-band filters can be realized with interface media having characteristics of Z0 ≈ 85 Ohm (ε ≈ 19.7) in the case of a forward step of the characteristic impedance at the edge interfaces of the structure and Z0 ≈ 53 Ohm (ε ≈ 50.4) – in the case of the reverse step (inversely proportional to the original). It is demonstrated that for the structures with the edge quarter-wave layers (all the inner layers are half-wave), other things being equal, the selective properties become better, but the relative passband can vary from only 45% to 115%, while the lower limit is achievable only in the case of air interface media (Z0 ≈ 377 Ohm, ε = 1).

The methodological approach to estimation the statistical radar characteristics (mean, median and rms-square deviation values of RCS) of an object using a spatial diagram of backscattering formed in nodes of an equidistant azimuthal-angular coordinate grid is presented. The proposed approach is tried out using the model spatial diagram of backscattering of the tested object. The approach is based on the assumption of the uniform law of distributing he views of an object and implements the formation of a variation series from the samples of the RCS diagram weighted with the probability density function of the location angles. The values of the function are determined by the ratio of the area surrounding the node of the grid cell to the total area of the location sector corresponding to the solid angle 4π. The calculation of areas of cells having the shape of spherical polygons is implemented using the relations of geometry of constant curvature regions. The proposed approach is tried out using a model spatial diagram of backscattering of a test object. To verify the obtained results, a simulation model of formation evenly distributed points on the surface of a spherical coordinate grid describing the observation of an object from random equivocal angles has been developed.

The description of the device and the principle of operation of a new type of autodyne transceiver of short-range radar systems (SRRS), made on the basis of an optoelectronic oscillator (OEO), is presented. The antenna is connected to the OEO through a dividing-decoupling device (DDD), which provides, on the one hand, conditions for generating self-oscillations in the system and, on the other hand, transmitting and receiving radio signals with minimal losses. The scheme of the DDD and the method of calculating their parameters are considered. A mathematical model of the autodyne system based on the OEO has been developed, and the basic relations for determining its parameters and characteristics have been obtained. It is demonstrated that the use of OEO provides a significant increase in the equivalent Q-factor of the oscillator system and the reduction in its own noise. The improvement of these parameters of the autodyne SRRS will significantly increase the range of operation, expand the range of operating frequencies and the scope of their application. The prospects of using autodynes based on OEO in the creation of detection systems of objects with a small effective scattering area, such as unmanned aerial vehicles, for protection against which the use of conventional (distant) radars is ineffective, are noted.

A campanha de imunização contra a COVID-19 foi iniciada no Brasil em Janeiro de 2021 após forte pressão da sociedade sobre o governo federal, que havia criado uma série de empecilhos ideológicos contra as vacinas, sobretudo, as produzidas com insumos chineses. Este artigo analisa o impacto da ideologia de extrema direita na distribuição espacial da cobertura vacinal contra Covid-19 nos municípios brasileiros. Por meio de modelos hierárquicos multiníveis de dois estágios identificou-se que, mantido constantes características sócio demográficas e as estruturas do Sistema Único de Saúde, o grau de bolsonarismo nos municípios impactou negativamente as taxas de cobertura da primeira, da segunda e, especialmente, da terceira dose.
Investigation of the Usage Characteristics of Environmentally Friendly Water-Repellent Chemicals on Cotton Fabrics
Authors: Kartal Gülşah Ekin
Published: November 2022

Fabrics with water-repellent properties are widely valued in the textile industry. It is known that fluorocarbon compounds, which are widely used for this purpose, are harmful to the environment. Therefore, within the scope of this study, a water-repellent chemical that does not contain fluorocarbon compounds was used to treat 100% cotton fabrics and compared with fluorocarbon compounds. The results show that the environmentally friendly chemical is at least as effective as the fluorocarbon compounds. According to the spray test, water repellency at ISO 5 level was obtained. In addition, the fabrics’ usage properties were assessed and high water vapour permeability, air permeability and low bending stiffness (280 mg cm) were obtained. This has yielded important results in terms of sustainability and the potential for eliminating the use of fluorocarbons for this application.
Wooden architectures: a cartography of Lages-SC

Published: November 2022

The primary interest in this article focuses on analyzing the wood architecture in the context of the city of Lages, in the State of Santa Catarina. A work that is produced as an unfolding of other actions and that seeks to build a cartography of wood architectures from the macro-region of the State of Santa Catarina, to a microterritoriality, analyzing the details of a wooden shed in the municipality of Lages-SC. The data used come from bibliographic references and clues about wood architectures derived from a fieldwork, with exploratory character and subject to discovery, surprise and unforeseen circumstances. In this historical process, the architecture in madeira catarinense, in general, accompanied the process of historical, cultural and economic transformation of its context. It begins with indigenous housing, methods brought by Portuguese settlers with the incorporation and adaptations to local resources, changing, later, with the arrival of European immigrants, especially during the nineteenth century, in view of the diversity of cultural traditions and the intensification and mechanization of logging. Thus, it seeks to draw, through data and clues, cartograms that map the wood architecture, in order to characterize its cultural traits, technological roots and vernacular ties. A process that intends, thus, to record the riches of knowledge widespread in most of the construction of popular dwellings in the State of Santa Catarina.
