The main objective of the study was the determination of the impact of petty trading on household livelihood among women petty traders in Akwanga Local Government Area (LGA) of Nasarawa state. This was achieved through two specific objectives – to determine the contributions of women petty trading on household income, and its role in attaining household living standard. The study relied on the use of primary data, obtained from a random sample of 343 women owners of petty businesses in Akwanga. Data was collected through a questionnaire survey involving the administration of copies of a structured questionnaire with closed-ended items forming each variable scale. The collected data was used to estimate a structural model using the PLS-SEM statistical technique, to test the pertinent formulated hypothesis and evaluate variable relationships. The result obtained showed that women petty trading businesses had positive and significant effect on household income and living standard.  in Akwanga. It was therefore, recommended that due to the importance of petty trading into our growing economy, government and non-governmental organization should encourage more women to go into trading by supporting them with adequate finances for development and women petty traders need to analyzed the kind of business they want to engage onto so as to reduce the magnitude of certain uncertainty in the future.
The Story of the Brain's Becoming-Mind
Authors: Ferreira Filipe
Published: July 2023

Can the brain become mind? If the question seems strange, aberrant even, it is perhaps due to the way the problem brain–mind is commonly presented, where what's repeatedly asked is whether the brain is or isn’t ‘mind’. Yet, if we take Deleuze and Guattari's provocation seriously, in the Conclusion of What is Philosophy?, the problem is radically recast: even if speculatively, that is, properly philosophically or conceptually, the brain, for them, involves its own becoming, both in terms of its ‘becoming-subject’ and ‘becoming-mind’, as ‘Thought-brain’. I will explore references within Deleuze's philosophy in relation to the brain, namely in The Logic of Sense and his work on cinema, as I try to work out what this fantastic story (with necropolitical undertones) may in fact look like, the one where the brain not simply is but becomes, and in becoming, becomes mind…
The use of transcutaneous bilirubin nomograms for the prevention of bilirubin neurotoxicity in the neonates
Authors: Casnocha Lucanova Lucia , Zibolenova Jana , Matasova Katarina , Matasova Katarina , Zibolen Mirko
Published: July 2023

Purpose

Although neonatal jaundice is a ubiquitous and predominantly benign phenomenon, the risk of neurotoxicity exists in a number of infants with unconjugated hyperbilirubinemia. Plotting bilirubin values on nomograms enables clinicians to employ an anticipatory and individualized approach with the goal of avoiding excessive hyperbilirubinemia and preventing acute bilirubin encephalopathy and its progression to kernicterus. We aimed to construct nomograms for White term infants based on transcutaneous bilirubin (TcB) measurements using a JM-105 device.

Methods

TcB measurements were taken in infants at ages ranging from 0 to 96 postnatal hours. We then constructed hour-specific TcB nomograms from forehead and sternum measurements in infants who did not require subsequent phototherapy.

Results

We included 2,981 TcB measurements taken on the forehead and 2,977 measurements taken on the sternum in 301 White term newborn infants. We assessed the predictive abilities of the nomograms at six postnatal time intervals using receiver operating characteristic curves. The areas under the curves indicated reasonable prediction of hyperbilirubinemia requiring phototherapy, except for the forehead measurement taken within the first 12 h of life. Sensitivity tended to rise as postnatal age increased.

Conclusion

The nomograms illustrate dermal bilirubin dynamics in White term neonates during the first 4 days of life. They may be useful tools to predict individualized risk of hyperbilirubinemia requiring treatment, and to plan optimal follow-up of infants at risk of bilirubin neurotoxicity.

Published: July 2023

The aim: To evaluate the structural changes of the brain in relation to the formation of cognitive disorders (CD) in patients with arrhythmias
Materials and methods: 147 patients with different clinical forms arrhythmias against the background of ischemic heart disease were examine. At the first stage, all patients with arrhythmias assessed cognitive functions. At the second stage, patients were distributed divided into two groups: the main group patients with CD, control – patients without CD. These groups underwent computed tomography examination of the brain.
Results: CD were established in 83% patients with arrhythmias. Mild CD were more often diagnosed in patients with persistent form of atrial fibrillation (AF), severe CD – in patients with permanent form of AF and atrioventricular blockade ІI-III degrees. Neuroimaging changes were found in 73.8% patients with CD and in 36% patients without CD. They were manifested by atrophic changes of the cortex, internal hydrocephalus, a decrease in the density of the brain sub¬stance of the periventricular area. In patients with CD, compared to patients without CD, showed lacunar foci with predominant localization in the parietal and frontal lobes of the brain, periventricular and subcortical leukoaraiosis. Multiple correlations were established between CD and structural changes of the brain.
Conclusions: The increase in the severity of CD in patients with arrhythmias is associated with atrophic changes at the cortical-subcortical level, accompanied by the phenomena of internal hydrocephalus, periventricular and subcortical LA, lacunar foci, with a predominant localization in the frontal-temporal-occipital lobes, in the visual hump and basal ganglia of both cerebral hemispheres.

Determinants of green bond issuance: agency or stakeholder motives matter?
Authors: GLAVAS Dejan
Published: July 2023

We investigate the underlying reasons for a firm to issue green bonds using agency and stakeholder theory as frameworks. We testhow different proxies for each theory explain the decision to issue a green bond. We also test whether these proxies are relevant togreen bond issuance amounts. We perform logit and fixed effects regressions using a dataset of green bond issuers and non-issuersin 27 countries for the 2013 to 2017 period. Our findings suggest that the agency motive is a key determinant of the decision to issuea green bond. However, agency issues seem to have only a partial impact on the size of the green bond issuances.

PUBLIC-PRIVATE PARTNERSHIP IN FINANCING ADULT EDUCATION: IMPLICATIONS FOR SUSTAINABLE DEVELOPMENT IN NIGERIA
Authors: Daerego I. Taylor , David B. Jack , C. Wami Kevin
Published: July 2023

Adult education is concerned with developing the adult population of a country to become useful to themselves and their societies. It is aimed at equipping adults with the right knowledge, skills and attitudes required to actualize their full potentials, and then depends on them to, in turn, apply themselves to the all-round development of their societies. In Nigeria, adult education is relevant and strategic in the development of the nation. However, there are many challenges to adult education in Nigeria. One of such challenges is poor funding. The cause of poor funding is government’s inability to single-handedly finance adult education in Nigeria. This, therefore, underscores the need for an alternative means of funding adult education which is very important to national development – a joint effort, sort of, in financing adult education towards sustainable development in Nigeria. To this end, a public-private partnership (PPP) becomes a necessary avenue. This paper examined the nature of public-private partnership in financing adult education and its implications for sustainable development. The authors relied on qualitative data from theoretical sources and recommended ways through which the Nigerian government can build synergy with private individuals and organizations in financing adult education towards sustainable development in Nigeria.

Effect of Multiple-Walled Carbon Nanotubes (MWCNTs) on Asphalt Binder Rheological Properties and Performance
Authors: Ezzat Estabraq N. , Al-Saadi Israa F. , Jasim Abbas F.
Published: July 2023

Growing traffic loads, soaring summer temperatures, and moisture damage will render conventional asphalt binder insufficient to maintain the performance standards of asphalt concrete pavement. Thus, it is necessary to modify the virgin asphalt using various polymers or nanomaterials. The primary goal of this research was to examine the rheological effects of combining multiple-walled carbon nanotubes (MWCNTs) and styrene butadiene styrene (SBS) in an asphalt binder. In this study, MWCNTs and SBS were mixed with virgin asphalt at concentrations of 1%, 3%, and 5% by weight. The performance grade (PG) and asphalt binder qualities were determined through Superpave system testing. The addition of 1% MWCNTs had no effect on the (PG) of virgin asphalt, whereas the addition of 3% and 5% MWCNTs resulted in increases of 2° and 4°, respectively. When 1% SBS is added to asphalt, the PG rises by an average of 1°; when 3% and 5% SBS are used, the PG rises by an average of 2° and 3°, respectively. The results also showed that the rutting parameter (G

Measuring the Gender Asset Gap: Evidence from Spain
Authors: Ruiz Juan Rafael , Stupariu Patricia , Villanueva Paloma
Published: July 2023

While the income gender gap has been widely researched to date, less attention has been paid to the wealth gender gap. This paper analyses individual-level data of the Spanish tax agency between 2012 and 2017 and documents the existence of an increasing wealth gap in Spain in this period. It also finds a clear difference in wealth accumulation patterns between both genders, especially in what respects holdings of equity in productive companies. Additionally, it finds that both women and men in the highest quantiles of the wealth distribution have increased their wealth and that men hold more assets that women. With respect to income distribution, the data shows men’s income accounts for a larger share of total income, which reinforces the gender gap related to economic resources.

Published: July 2023

Subject of research: the paper presents a method of hard alloy fabrication via spark plasma sintering technology performed for mechanically activated powders of mixed WC compositions with 10 wt % Co.

Methods and objects of research: mechanical activation of the powders was carried out in a ball planetary mill by wet milling/stirring in anhydrous isopropanol medium using a milling container and balls made of WC.

Main results of research: the paper presents experimental data on the densification dynamics (kinetics and sintering stages) during spark plasma sintering at temperatures of 1000, 1100, 1150 and 1200 С. The results of studies of the phase composition, microstructural organization and physical and mechanical properties of WC-10wt.%Co hard alloy are given. Optimal sintering parameters (1200 C, 9 min) are determined. Hardness and mechanical strength of WC-10wt.%Co hard alloy samples increase as the sintering temperature increases with reaching the density of 99.6 % of the theoretical value. It is shown that with increasing temperature from 1000 to 1200 C the average WC grain size slightly increases from 3.3 m to 3.9 m with increasing contribution of the share of larger grains with size 4 m.
Synthesis of Steroids
Authors: Muzaffar Aneesa , Muzaffar Umaiya , Donepudi Rakesh
Published: July 2023

The term steroid pertains to a broad spectrum of molecules with varying
physiological roles. More explicitly, they are a class of compounds that are naturally
produced in the body of living organisms as well synthetic or semi-synthetic molecules.
They have tremendous effects on biochemical processes and thus any aberration from
the required physiological range can have potential effects. Moreover, due to the
therapeutic potential of steroids for the treatment of a wide range of diseases, many
synthetic approaches have been made available to the organic chemist for their
synthesis. Most of the steroids that are in use as drugs are still prepared by modifying
naturally occurring steroids (partial synthesis). This chapter highlights the biosynthetic
pathways of steroids and the approaches to chemically synthesize them because of their
biological and synthetic relevance.

of the human visual system begins within the womb, and there is
experimental motivation to explore the extent to which light penetrates
maternal abdominal tissue. In this study, we develop and adapt a Monte
Carlo model that simulates third trimester histological properties of
maternal tissue in order to understand the extent to which the womb is
illuminated by external point light sources. We next use the results of
this mathematical modelling to determine approximate levels of third
trimester uterine illumination and suggest improvements for future
experimental work.

Climate change is a current phenomenon and represents one of the most important environmental, social and economic threats to the planet and is defined as a significant and lasting change in local and global weather patterns caused by natural or human-caused global warming. The construction of works related to earthworks such as paving of streets, parking lots, roads, highways, dams, canals, among others, generate pollution because they use heavy machinery which is a major consumer of non-renewable fossil fuels that are transformed into emissions of Carbon Dioxide (CO2). The present work, takes as a case study the paving of a subdivision in the City of Obregon Sonora (Mexico) to determine the carbon footprint in Kg of CO2eq/m2 generated in the machinery, using the methodology of the carbon footprint from the quantities of work of the construction process, the selection and hourly performance of the appropriate equipment, the determination of the volumes of fuel used and the emission factor in Kg-CO2eq for the fuel used. The results obtained were 165,742.02 Kg-CO2eq in a surface of 128,049.59 m2 of paving, equivalent to 1.29 Kg-CO2eq/m2.

Abstract

Material Sugarcane natural fiber material can be used as a sound absorber material. In measuring the value of the sound absorption coefficient of the cane natural fiber silencer using the sound level meter application on the smartphone to measure the intensity of sound (dB) and the frequency generator application connected to the speaker as a sound source (Hz). The test uses an acoustic box as a miniature room that will be tested for its sound absorption coefficient values coated with sugarcane natural fibers. The purpose of this study is to find out the influence of sugarcane fibers in reducing noise and to find out the effect of frequency variations on the value of the sound absorption coefficient. Measurement of the noise level of the sugarcane natural fiber material on the acoustic wall produces different sound absorption coefficient values based on variations in the frequency of the sound source. The greater the frequency value, the higher the absorption coefficient value. Frequency variations used include 500 Hz, 1000 Hz, 1500 Hz, 2000 Hz, 2500 Hz, and 3000 Hz. The value of the sound absorption coefficient drops at a frequency of 1000 Hz but there is a re-increase at frequencies above 1500 Hz. The smallest sound absorption coefficient is obtained at the time of frequency 1500 Hz with a value of = 0.01047 and the largest at the time of frequency 3000 Hz with a value of = 0.10139. The coefficient value is too small, so it is not effective in muffling the sound.

Introduction. Repair of pipelines under pressure of pumped media by means of welding is relevant to reduce the complexity of work. However, it may reduce the safety of work. To solve this issue, the authors consider applying the technological processes of machine welding with controlled drop transfer.

Aim. To determine the main parameters of technological processes of machine welding with controlled drop transfer, affecting the safety of welding.

Materials and methods. The authors developed a theoretical model for calculating the working thickness of a pipeline wall under pressure which they used for calculating the strength during welding. The dependence of the pipeline wall thickness at the edge of the penetrated hole on the internal pressure was also used in the calculations.

Results. It was found that machine welding with controlled transfer of metal drops allows the wall penetration depth to be regulated by changing the welding variables. This significantly increases the safety of welding on pipelines under pressure of pumped media, compared to other types of welding. The developed welding processes ensure the safety of welding operations by means of a smooth and accurate control of the wall penetration depth. This is achieved by the correct selection of the background and peak current, control of the drop transfer process by arc voltage, control of the amount of weld metal and the heating temperature of welded structures.

Conclusion. Recently, a number of repair technologies have been developed to improve the quality of welds in the construction and repair of trunk pipelines. The highly significant results of research on the development of machine welding technology with controlled drop transfer allow this technology to be recommended as an effective way to improve the safety of welding operations on pipelines under pressure of pumped media.

Authors: Sadaf Maisha
Published: July 2023

Various technological platforms have become prominent in recent times for communication. It is hard to survive for educated people in this modern world without effective communication. People use various technological tools for mutual interaction. These technological aspects are Facebook, Twitter, YouTube, Messenger, WhatsApp, and others. Among these instruments, instant messaging applications are the popular means through which students can share their ideas on how they can improve their English language skills. Group messenger or WhatsApp chatting are significant ways through which more than two students can discuss their study materials collaboratively. In this context, the main objective of this research is to find out the contributions of online group chatting to interactive English language learning. Many Bangladeshi tertiary-level students do not have proper knowledge about the use of technological tools. This study will help them to understand how messenger\WhatsApp chats can create an interactive and friendly environment among English language learners. The researcher followed qualitative research methods for this study. The researcher took semi-structured interviews with ten participants, all drawn from a renowned private university of Bangladesh. However, findings inform us that online messaging platforms help students to improve their English language in a rapid way. On the contrary, the researcher also found that students sometimes face difficulties while sharing their ideas in English through messenger\WhatsApp or other online applications. Finally, some recommendations have been proposed in light of the research findings.
Communal solidarity and the challenge of intergenerational punitive system in Africa: The Yoruba experience
Authors: Aina Adebayo A. , Adefarasin Victor O.
Published: July 2023

The transference of qualitative punitive system in Africa to the next generations is challenged by the hegemonic situations created by the Western colonial ‘theory-maker’. The reality of this formal structure promotes individual character of the law which undermines the transformative cultural principles for intergenerational legal justice in Africa. This paper, therefore, examines the communal solidarity system within the Yoruba culture in order to arrive at the socio-legal sustainability discourse for the next generations. The study employs the conceptual, critical and reconstructive methods of philosophy with a view to sustaining communal solidarity for intergenerational punitive system. The findings show that communal solidarity in Yoruba culture goes beyond the formal Eurocentric principles that celebrate individualistic for a coherent interconnection among social structure, law and belief system towards the certitude and trust making for harmonious human well-being and future generations. Also, it promotes a restitutive principle whereby the offender is reconciled to himself, the victim and the community at large, which seals generational bond not only within the family but the community at large. More so, the notion advances a creative and flexible human activity, whereby human beings are amenable to change and deserve integration into the community with the saying that bi a ba fi owo otun na omo eni, a fi t’osi fa’a mora (when a man beats his child with his right hand, he should draw him to himself with his left hand). Therefore, the study constructively addresses the dispensation of justice with legal certainty, legal diversity and social order for maximally advanced and sustained future.
