Authors: Muhsin Muhannad Y. , Mohammad Zainab F. , Jihad Noor J. 
Published: November 2024

Abstract
This paper provides a system architecture to evaluate the results of high dynamic range orthogonal frequency division multiplexing (OFDM) as a technique to transfer the 64-quadrature amplitude modulation (QAM) basebands signal over fiber, for the signals of the fifth generation/new radio (5G/NR) broadcasting at 28 GHz suitable for millimeter wave (mm-wave) applications. With this radio-over-fiber (RoF) system, the Optiwave Opti-system software (2024) is used for the assessment research. The integration of 64QAM-OFDM and RoF methods has led to a reduction in wireless network costs while maintaining a high data rate. This paper shows the RoF system design, for a 100 MHz 5G/NR signal broadcast at 28 GHz, results the largest dynamic range for millimeter wave applications. With an optical modulator design of the IF and LO signals, 64-QAM OFDM is possible. Better dynamic range may be achieved by using this approach to eliminate the error in optical bands before the photo recognition process. The optical spectrum of the transmitted signal, signal to noise ratio (SNR), error vector magnitude (EVM), and the cancelation diagram serve as the foundation for the performance analysis. Based on the acquired results, the system that is being presented is a strong contender for mobile communication systems in the context of 5G and beyond.
High yield of congenital hypothyroidism among infants attending Children Hospital, Nairobi, Kenya. Facility based study in the absence of newborn screening
Authors: Kahssay Menbere , Ngwiri Thomas 
Published: November 2024

Abstract

Objectives
Congenital hypothyroidism (CHT) is a treatable cause of intellectual disability. Late diagnosis and delayed initiation of treatment leads to irreversible neurodevelopmental and intellectual disability. Thus, newborn screening is crucial. However, 71 % of babies are born in an area with no established newborn screening program and Kenya is not an exception. We aimed to determine the incidence of CHT, developmental outcomes of patients in the absence of newborn screening.

Methods
A retrospective data of subjects who met the inclusion criteria, newborn and infants from 3 days to 2 years whose thyroid function test (TFT) was undertaken during well baby visit or clinical suspicion of CHT were collected. Laboratory reference range for age was used to interpret the result and TSH>10 Uiu/mL after 6 weeks of life is considered abnormal according to ESPE guideline. Developmental outcome of children was collected from patient file documented by primary physician and parental concern.

Results
Of 1,426 children met inclusion criteria, 90 had elevated TSH. Out of which 70 repeat TFT showed normal TSH and free T4. The incidence of abnormal TSH across the different age groups was 2.4 , 7.2 and 10.5 % for ages 0–29 days, 1–11 months, and 1–2 years, respectively with p-value of =0.0002. While 20 cases with CHT identified with incidence of 14 per 1,000 children (1.4 %; 95 % CI: 0.9–2.1 %). Out this 12 (60 %) had poor developmental outcomes. Down’s syndrome was the common associated condition 9/20 (45 %). All cases were primary CHT.

Conclusions
This study shows high incidence of CHT in a small cohort of patients over 5-year period with poor development outcome.

Millennials are the largest generation in the American workforce, so their workplace needs are critical for employers to understand. As this paper will explore, Millennials are advocating for the types of changes that benefit all workers, regardless of generation, such as living wages, comprehensive and affordable health coverage, schedule or location flexibility, and better management practices.
Emotions of food influencers regarding digital work and the transmission of food knowledge on Instagram
Authors: Mairano Maria Victoria 
Published: November 2024

Abstract

Purpose
This article aims to problematize influencers’ emotional ecologies regarding their digital work as content generators and the emotional ecologies recorded in the food practices they share on their profiles.

Design/methodology/approach
Semi-structured digital interviews and a digital ethnography process in the feeds of the influencers who responded to the interview.

Findings
We find some similarities in the emotional ecologies we analyze. The influencers’ posts reference emotional ecologies such as love for sharing content, eating with others, and cooking, and tiredness referred to planning the meal, cooking, and liking/enjoying concerning eating with others and sharing content. While in the interviews, it has been possible to elucidate the emergence of the logic of pleasure and happiness about showing/reflecting, sharing content, and inspiring and transmitting something to the other, and satisfaction combined with indifference or tiredness, in some cases, concerning the work itself as influencers.

Practical implications
Analyzing digital consumption and the influencer phenomenon today provides us with tools to think about the current and future society. In the context of technological advances and digitalization processes, it is necessary to open the dialogue to discuss digital labor changes, new workspaces, workers’ relationships with companies/brands/corporations, and the involvement of bodies and emotions there.

Social implications
It problematizes the effects of digital consumption, food digital practices, and influencers’s work in everyday social practices.

Originality/value
This article addresses the criteria that organize the structuration regime of sensibilities on Instagram regarding food practices and the generation of content based on the figures of Argentinian food influencers.
The Impossibility of Representing the Sacrifice of Abraham and Isaac in Barnett Newman’s Painting
Authors: Hoványi Márton 
Published: November 2024

Abstract
One of the archetypes of the Judeo–Christian (and Muslim) sacrifice is the story of Abraham and his beloved son, Isaac. The central element of the Akedah (Binding of Isaac) narrative, which moves not only theological but also philosophical discourse, is the vulnerability of the human body, the depiction of which is unimaginable in both the Jewish and Muslim religious beliefs. The sacrifice and body, as well as the ancient correspondence between these two, can be visualized in Barnett Newman’s painting Abraham (MoMa, New York/NY, 1949) created in the decade of the end of World War II. This study interprets the painting, which is painted on a dark background, as a strange and outstanding work of Newman’s abstract expressionism. The nonfigurative image creates an opportunity for a diversity of interpretations. These interpretations can be traced back from the biographical context through the national trauma of the twentieth-century Holocaust to the biblical book of Genesis. In the course of theology and comparative literature and cultural studies interpretations, the visualization of the drama of Abraham and Isaac gradually emerges, deconstructing again and again the approaches that seemed to be predictable before. The study ventures to compare Newman’s painting with as many interpretations of the title “Abraham” as possible, so that such comparisons may lead to just as many different interpretations of the image and the text.
Monumental Artworks as Difficult Heritage
Authors: Daly Selena 
Published: November 2024

Abstract
In 1936, Benito Mussolini invaded and occupied Ethiopia. The following year, he declared that Sicily represented „the geographical centre of the Empire“. This new Fascist empire and Sicily’s role within it gave rise to numerous interventions into the island’s urban landscape, from renaming streets and installing commemorative plaques to commissioning monumental colonially-themed artworks. It is on this last category that the present article focuses, examining three such works: two frescoes by Alfonso Amorelli for a privately-owned shopping arcade in Palermo; a mosaic by Michele and Basilio Cascella for a train station in Messina; and a series of frescoes by Gino Morici and Pippo Rizzo for the reception rooms of the local government headquarters in Ragusa. The article explores both the genesis of these works and then, primarily, the factors that have influenced their reception from the end of the Fascist regime in 1943 to today, considering the visibility of the works to the general public; their perceived quality and the artist’s reputation among art historians and critics; and the political and historical moment. Ultimately, the article asks to what extent these artworks should be regarded as examples of „difficult heritage“ and what the management of them in postwar Italy can reveal about memories of Fascist colonialism today.
Prolegomenon to Irenaeus’ Epistemology: The Source of
Adversus haereses
2,13,2 and the Five Powers of the Mind Tradition
Authors: McCashen Grayden 
Published: November 2024

Abstract
In AH 2,13,2 Irenaeus describes the activity of the mind as unfolding in a five-stage process, with each stage having a distinct name: ennoia, enthymēsis, phronēsis, boulē, and dialogismos. His account manifestly draws on philosophical psychology and epistemology, which has led scholars to assume he is using a source written by a member of one of the classical schools, a Stoic, Platonist, etc., whence he also derives his terms for the mind’s activity. This article argues to the contrary that Irenaeus drew the terminology for the five stages of the mind’s movement from his opponents. The terms themselves better fit a Jewish or Christian milieu than as technical terms of philosophical psychology. Such was the milieu of Irenaeus’ opponents, and indeed, nearly identical psychologies appear in cognate Nag Hammadi texts as well as later Christian texts, such as the Acts of Thomas, and as the Manichaean five-powers tradition. It is possible to arrange these sources so as to explain the presence of the five-powers tradition in each, including Irenaeus, without appealing to an unknown philosophical antecedent. Having established this, the article concludes by answering objections to the thesis and offering a prospectus for further research.

Authors: Pereira Rita , Araújo Joana , Severo Milton , Ramos Elisabete , Oliveira Andreia 
Published: November 2024

BACKGROUND AND OBJECTIVES
Evidence is scarce on the clustering patterns of disordered eating dimensions or symptoms and their effects on future cardiometabolic health. This study examines associations of disordered eating trajectory profiles (from 13 to 21 years), with BMI and related cardiometabolic features at ages 21, 24 and 27.

METHODS
Participants are from the Epidemiological Health Investigation of Teenagers cohort (Porto, Portugal). At 13, 17 and 21 years, 3 Eating Disorder Inventory subscales were assessed (drive for thinness, bulimia and body dissatisfaction), and a latent class analysis derived trajectory profiles. Associations with BMI and having ≥1 metabolic syndrome feature at 21 (n = 1619), 24 (n = 916) and 27 years (n = 720) were tested using generalized linear models and binary logistic regressions.

RESULTS
The following 4 profiles were obtained: “higher” levels (highest severity of symptoms at all ages, 16-19%), “increasing” (especially of body concerns, 26-28%), “decreasing” (18-19%), and “lower” (highest proportion of individuals with low/without disordered eating, 35-37%). Compared with the lower levels profile, both sexes with higher and increasing disordered eating presented heightened BMI at 21, 24 and 27 years. Women in the higher levels profile had higher odds of having ≥1 metabolic syndrome feature at 21 and 24 years, while men with higher and increasing disordered eating presented increased odds at 21, 24 and 27 years.

CONCLUSIONS
Individuals, particularly males, with higher or increasing disordered eating levels from 13 to 21 years of age presented a higher risk of worsened cardiometabolic health up to 6 years later in adulthood.

The increase in the incidence of tuberculosis, especially in the post-Covid period, associated with the presence of latent infections and multiple drug resistance, dictates the need to develop new antimicrobial drugs. Here we wish to report the synthesis of 3,6-disubstituted 1,2,4,5-tetrazine derivatives containing N-, O- and C-nucleophile residues, as well as pharmacophoric hydrazone and oligooxyethylene fragments, and their screening against the pathogen Mycobacterium tuberculosis. Substances with pronounced antimycobacterial activity in vitro were identified (MIC = 0.18–3.12 μg/ml). An acute toxicity in vivo and membranotropic properties towards biometals have been studied for the most active compounds.

Published: November 2024

O convívio intergeracional, também no ambiente laboral, é uma realidade e traz implicações para a vida das pessoas. Portanto, demanda-se reconhecer a diversidade geracional entre os trabalhadores, desnudando e discutindo o ageismo. É nessa lógica que se tem como objetivo deste artigo analisar o ageismo ao longo continuum da vida laboral de professores universitários numa universidade comunitária. Para tanto, realizou-se um estudo, com pesquisa exploratório-descritiva e com abordagem qualitativa. Os dados foram coletados por meio de história de vida, grupo focal e pesquisa documental, possibilitando a triangulação dos dados na análise temática. Estereótipos positivos e negativos foram detectados como antecedentes ao ageismo ao longo da vida laboral dos pesquisados, confirmando a recorrência do ageismo, sobretudo nos anos inicias e finais da carreira docente. Acredita-se que os resultados da pesquisa trouxeram contribuições teóricas, principalmente na lógica decolonial e ao longo da carreira dos profissionais; contribuições práticas para as Instituições de ensino superior, ainda mais para a pesquisada; contribuições sociais, na medida em que estereótipos, preconceitos e discriminações são expostos; contribuições metodológicas em razão de que o tema é mais trabalhado quantitativamente e pouco se utiliza a história de vida enquanto técnica de coleta de dados e, a análise temática, como técnica de análise de dados. Assim, acredita-se no potencial da repercussão desta pesquisa na vida pessoal das pessoas, bem como na laboral e na sociedade.
Improved Seed Storage Technique in Groundnut (Arachis hypogaea L.) cv. G7 in Coastal Environment

Published: November 2024

Background: Non-availability of good quality seeds at the right time is a major problem faced by groundnut growers. Groundnut seeds lose their viability quickly due to several biotic and abiotic factors during storage. Seed moisture content, storage temperature and relative humidity are three major factors affecting seed storability in coastal environments. Generally, groundnut seeds are stored as pods in gunny bags. Those seeds lose their viability rapidly due to the moisture-pervious nature of the container. Vacuum storage techniques may help in protecting the seed quality from the external environment in coastal areas. Methods: With this background, the experiment was conducted with two major objectives, to prolong the seed storability of groundnut and to reduce storage volume by using the kernel storage method in the place of pod storage. Each 20 kilograms of freshly harvested pods and 10 kilograms of kernels of Groundnut cv. G7 were treated with double spectrum fungicide (Carboxin 37.5% + Thiram 37.5%) and stored in three different containers viz., Gunny bag, High-Density Poly Ethylene (HDPE) bag and Super grain bag comprising a total of 12 treatments and those were tested at bimonthly intervals to assess the quality. Result: The results shown that all the seed quality traits were differed significantly with duration of storage, storage container, method of storage and seed treatment. Irrespective of containers, untreated kernels lose their viability within a month of storage. Further, treated and untreated pods and kernels stored in gunny bags failed to fulfill the minimum germination standards (70%) after three months of storage. However, the kernels treated with fungicide and stored in HDPE or Super grain bags fulfilled minimum germination standards even after 11 months of storage. Hence, groundnut kernels treated with fungicide may be safely stored in Super grain bags or HDPE bags with reduced volume of storage as compared to pod storage. Accordingly, kernel storage in groundnut is possible if kernels pre-treated with double spectrum fungicide (Carboxin 37.5% + Thiram 37.5%) and stored in super grain bags or HDPE bags. Thus, the results have a high degree of practical utility for groundnut farmers and seed growers.

Backround: The strains of Bacillus thuringiensis bacteria (Bt-type) are utilized for controlling the brown-tail moth pest, Euproctis chrysorrhoea (Linnaeus, 1758), in apple orchards in Armenia from 2020 to 2022. Methods: The study focused on the brown-tail moth larvae in all developmental stages (I-VII) on the Renet Simirenko apple variety. Culture fluids, based on crystal-forming insecticidal strains BtEM-54 and BtEM-82 were employed. Result: Research has demonstrated that local BtEM-54 and BtEM-82 culture fluids exhibit significant biological efficiency against brown-tail moth larvae across various stages (I-II, III-IV, and V-VII) in both laboratory settings and apple orchards. Furthermore, no statistical differences were observed when comparing the biological efficiency factors of these scientific experiments with the standard lepidocide.

Background: Nutritional intake in preterm infants is associated with short- and long-term outcomes. The favorable outcomes of preterm infants who predominantly receive their mother’s own milk (MOM) are thought to be mediated partly through beneficial effects on the gut microbiome. When MOM is not available, donor human milk (DHM) is recommended as the best alternative. However, DHM is less effective in preventing adverse outcomes, which may be explained by compositional differences between MOM and DHM, resulting in different microbiome development. This systematic review focuses on the effects of predominant DHM vs. MOM feeding on the gut microbiota composition in preterm infants.
Methods: A comprehensive search was conducted across MEDLINE, Embase, and Cochrane databases. Eight out of the 717 publications identified were included. Data on gut microbiota composition, alpha diversity, and taxonomic differences between DHM- and MOM-fed preterm infants were extracted and analyzed.
Results: The microbiome composition was distinct between the two feeding groups. Alpha diversity measures were lower in DHM-fed infants, particularly when preterm formula (PF) was also provided. DHM-fed infants showed higher abundances of Staphylococcaceae and Clostridiaceae , and lower abundances of Bacteroidetes and Bifidobacterium .
Conclusion: The observed gut microbiome differences in DHM-fed preterm infants have previously been linked to adverse health outcomes. This underlines the importance of increasing the awareness of MOM intake in preterm infants. Further studies should explore the mechanisms through which human milk affects health outcomes.
ADSORPTION REMOVAL OF CU (II) USING NI-MODIFIED SILICA GEL

Published: November 2024

The contamination of surface and groundwater with heavy metals represents a significant threat to environmental safety and the health of living organisms. Consequently, the development of new technologies and the improvement of existing ones to clean water bodies from toxicants of various kinds represents an important task. One of the factors influencing the choice of treatment method is the concentration of the pollutant. It is advisable to use adsorption methods for the post treatment of water environmental to the levels of maximum permissible concentrations. In the context of the implementation of adsorption methods, the selection of sorbents that combine high efficiency and low cost with ease of preparation represents an important factor. The aim of this work is to produce a sorbent based on commercial silica gel and nickel oxide. For its synthesis, the thermolysis method was chosen. A series of materials with varying mass ratios of NiO to SiO2 was produced: 1:1 and 0.5:1. The presence of crystalline nickel oxide on the amorphous surface of SiO2 was confirmed by X-ray diffraction analysis. The main parameters of the porous structure were determined by the method of low-temperature nitrogen adsorption/desorption. With an increase in the amount of the deposited oxide layer, the specific surface area and pore volume of the obtained samples decrease by 1.5-2.5 times compared to the original SiO2. At the same time, the general character of the mesoporous structure is preserved. The optimal conditions for the removal of Cu (II) ions by nickel-containing composites based on silica gel (pH ~ 5.5; sorption time - 1 hour) were investigated. The adsorption kinetics is adequately described by a pseudo-second-order model, which indicates a high affinity of copper for the surface of such samples. It was demonstrated that the modification of the SiO2 surface with nickel oxide results in an enhancement of the sorption capacity of materials with respect to Cu (II) ions. The maximum value of copper sorption on the synthesised samples is 10 times higher than on the original SiO2.
Professionalism - A Must for the Oil Patch
Authors: Brown Bob Diggs 
Published: November 2024

Abstract
In spite of the shortage of technical personnel, the petroleum industry has realized tremendous benefits from improved technology. It can be anticipated this industry will apply compatible exotic developments from the space and oceanography programs to accelerate its own field of endeavor.
Webster defines profession: "A calling requiring specialized knowledge and often long and intensive academic preparation." From this definition it is readily accepted those charged with the development of technology are professionals. Closer analysis of Webster’s definition will indicate the inclusion of those responsible for the application of technical developments.
The advent of automated drilling and production control, subsea completions, and the adaptation of nuclear energy for equipment, dictates "professionalism in the oil patch."
The rapidity of application of new technology in the "oil patch" indicates another area of professional man power shortage. The effectiveness of the technological adaptations to the petroleum industry is related to "professionalism in the oil patch."
