Mentoring community service nurses in public health settings: Guidelines for nurse managers
Authors: Khunou Sisinyana H.
Published: March 2023

Background: Adequate mentoring and support of community service nurses (CSNs) in transitioning from the learning environment to the public health setting is pivotal. Despite this notion, the mentoring of CSNs is inconsistently implemented. It was therefore imperative that the researchers developed the guidelines that can be used by managers to mentor the CSNs.Aim: This article shares nine guidelines to ensure adequate mentoring of CSNs in public health settings.Setting: The study was conducted in public health settings designated for placement of CSNs, in South Africa.Methods: This study followed a convergent parallel mixed-methods design whereby qualitative data were obtained from purposefully selected CSNs and nurse managers. Quantitative data were obtained from 224 CSNs and 174 nurse managers, with the use of mentoring questionnaires. Semi-structured interviews were used on focus groups of nurse managers (n = 27) and CSNs (n = 28). Quantitative data were analysed with Statistical Package for Social Science software version 23, ATLAS.ti 7 software was used to analyse qualitative data.Results: The merged results evidenced that CSNs were not adequately mentored. The public health setting was not conducive to mentoring CSNs. Mentoring activities were not well structured. Monitoring and evaluation of mentoring of CSNs were not properly done. Evidence from merged results and literature were applied to develop mentoring guidelines for operationalising a mentoring programme for CSNs.Conclusion: The guidelines were: (1) creation of a positive mentoring environment, (2) enhancement of collaboration between stakeholders, (3) attributes of CSNs and nurse managers in the mentoring relationship, (4) enhance orientation for nurse managers and CSNs, (5) facilitation of mentor–mentee matching process, (6) conducting mentoring meetings, (7) capacity development for CSNs and nurse managers, (8) monitoring and evaluation of mentoring process, and (9) reflections and feedback.Contribution: This was the first CSNs’ guidelines to be developed in the public health setting. These guidelines could facilitate adequate mentoring of CSNs.

Authors: Munir Munir , Mailin Mailin , Alkaf Idrus
Published: March 2023

Scholars have widely discussed the paradigm of integration of Islam and science. Still, a model of integration of Islam and science that uses the reasoning of Martabat Tujuh [seven grades] has not been found. Therefore, this study sought to investigate the manuscripts of Shaykh Abdussamad al-Palimbani’s Martabat Tujuh in the integration of Islam and science. This study used a descriptive qualitative approach, and data collection techniques were documentation and interviews. This study found two spiritual reasons in the manuscript of Shaykh Abdussamad al-Palimbani’s Martabat Tujuh: tanazzul [move down] deductive reasoning and taraqqi [move up] inductive reasoning.Contribution: The article contributed to developing the integration of Islam and science in Indonesia. The manuscripts of Martabat Tujuh [seven grades] by Shaykh Abdussamad al-Palimbani offer the circular motion of Martabat Tujuh as a model for integrating knowledge. The circular motion model of Martabat Tujuh is expected to be used as a theoretical basis for applying knowledge integration at various Islamic universities in Indonesia.
Job stressors, work tension and job satisfaction of academics at a university in South Africa
Authors: Luzipho Ncumisa , Joubert Pierre A. , Dhurup Manilall
Published: March 2023

Orientation: Stress in the workplace is a common phenomenon that is classified in different ways and which also impacts academics. Previous research highlighted that job stressors in the workplace have been considered an important contributor towards low levels of job satisfaction (JS) for academics. This perspective aids the study of the influence of job stress on JS.Research purpose: The aim of this research was to establish the influence of role conflict (RC), role ambiguity (RA), role overload (RO) and time pressure (TP) on work tension (WT) and the influence of WT on JS among academics at a university of technology.Motivation for the study: The impact of the coronavirus disease 2019 (COVID-19) pandemic and the reduction of government and associated agency funding changed the scenario of academic life from being considered idyllic, autonomous and well protected. Congruent to these constraints, changes in the diversity of students and advances in technology, blended learning and the introduction of learning platforms created further challenges in the way students learn and how modules were offered.Research approach/design and method: The researchers used a postpositivist quantitative paradigm with a convenience sample (n = 250) of academics in a university of technology in Gauteng. A structured questionnaire encompassing the study constructs was used.Main findings: Results showed positive associations between RC, RA, RO and TP on WT. Further, WT and JS showed negative yet significant predictive relationships with JS.Practical/managerial implication: It is pivotal for universities to understand the effects of job stressors on job satisfaction to improve the working conditions for academics.Contribution/value-add: This research provides findings to the present body of knowledge among academics on the influence of job stressors on WT and WT on JS at HEIs. Research on job stress and JS has been of interest in many HEIs. The research makes a valuable contribution to the university management, especially the human resource division, on the effect of levels of job stressors (RC, RA, RO and TP) on WT among academics.

Authors: Ismail Sumaya , Malherbe Francois , Panieri Eugenio , Cairncross Lydia , Boltman Gaseeda , Davidson Florence E.
Published: March 2023

Background: The radioguided occult lesion localisation (ROLL) technique was introduced at Groote Schuur Hospital in 2003 replacing the wire-guided localisation (WGL) technique. In the case of preoperative histologically proven impalpable breast cancers, a sentinel lymph node (SLN) biopsy was done simultaneously (sentinel node [SN] with occult lesion localisation or SNOLL).Aim: To assess the efficacy of the ROLL and SNOLL techniques for diagnostic and therapeutic excisions.Setting: A retrospective record analysis of 190 patients who underwent a ROLL procedure for diagnostic or therapeutic excision of occult breast lesions was performed at a large tertiary hospital in the Western Cape.Methods: Data were collected on patient and tumour characteristics, successful localisation rates, the volume of tissue removed, complete tumour resection rates, the number of re-operations performed and the proportion of SLN detection. The Pearson’s chi-squared test was used to test for significance between variables at α = 0.05.Results: Correct radiopharmaceutical placement was achieved in 177/190 (93.2%) lesions. Histologic examination of excised specimens confirmed 115/190 (61.0%) malignant and 75/190 (39.0%) benign lesions. Involved margins were found in 37/115 (32.2%). Complete excision with adequate margins occurred in 50/70 (71.4%) of cases of invasive cancer and in 11/45 (24.4%) of ductal carcinoma in situ (DCIS). The SN was successfully identified in 30/37 (81.1%) of SNOLL cases.Conclusion: Radioguided occult lesion localisation is an effective tool in the preoperative localisation of occult lesions for surgical biopsy as well as the removal of impalpable breast cancers. A single intratumoural injection with 99mTc nanocolloid combined with lymphoscintigraphy is a reliable method of localising the SN.

The Geometry of Hyperbolic Curvoids
Authors: Hoshi Yuichiro
Published: March 2023

The main purposes of the present paper are to introduce the notion of a hyperbolic curvoid and to study the geometry of hyperbolic curvoids. A hyperbolic curvoid is defined to be a certain profinite group and may be considered to be “group-theoretic abstraction” of the notion of a hyperbolic curve from the viewpoint of anabelian geometry. One typical example of a hyperbolic curvoid is a profinite group isomorphic to the ´etale fundamental group of a hyperbolic curve either over a number field or over a mixed-characteristic nonarchimedean local field. The first part of the paper centers around the establishment of a construction algorithm for the “geometric subgroup” of hyperbolic curvoids and a construction algorithm for the “collection of cuspidal inertia subgroups” of hyperbolic curvoids. Moreover, we also consider respective analogues for hyperbolic curvoids of the theory of partial compactifications of hyperbolic curves and the theory of quotient orbicurves of hyperbolic curves by actions of finite groups.

In this article, we prove the integrality of

v

-adic multiple zeta values (MZVs). For any index

\mathfrak{s}\in\mathbb{N}^r

and finite place

v\in A := \mathbb{F}_q[\theta]

, Chang and Mishiba introduced the notion of the

v

-adic MZVs

\zeta_A(\mathfrak{s})_v

, which is a function field analogue of Furusho's

p

-adic MZVs. By estimating the

v

\zeta_A(\mathfrak{s})_v

, we show that

\zeta_A(\mathfrak{s})_v

is a

v

. This result can be viewed as a function field analogue of the integrality of

p

-adic MZVs, which was proved by Akagi–Hirose–Yasuda and Chatzistamatiou.
Task offloading under deterministic demand for vehicular edge computing
Authors: Li Haotian , Li Xujie , Shen Fei
Published: March 2023

In vehicular edge computing (VEC) networks, the rapid expansion of intelligent transportation and the corresponding enormous numbers of tasks bring stringent requirements on timely task offloading. However, many tasks typically appear within a short period rather than arriving simultaneously, which makes it difficult to realize effective and efficient resource scheduling. In addition, some key information about tasks could be learned due to the regular data collection and uploading processes of sensors, which may contribute to developing effective offloading strategies. Thus, in this paper, we propose a model that considers the deterministic demand of multiple tasks. It is possible to generate effective resource reservations or early preparation decisions in offloading strategies if some feature information of the deterministic demand can be obtained in advance. We formulate our scenario as a 0‐1 programming problem to minimize the average delay of tasks and transform it into a convex form. Finally, we proposed an efficient optimal offloading algorithm that uses the interior point method. Simulation results demonstrate that the proposed algorithm has great advantages in optimizing offloading utility.
Modeling of Human Thermal Comfort
Authors: McGuffin Rom
Published: March 2023

Current vehicle climate control systems are dramatically overpowered because they are designed to condition the cabin air mass in a specified period of time. A more effective and energy efficient objective is to directly achieve thermal comfort of the passengers. NREL is developing numerical and experimental tools to predict human thermal comfort in non-uniform transient thermal environments. These tools include a finite element model of human thermal physiology, a psychological model that predicts both local and global thermal comfort, and a high spatial resolution sweating thermal manikin for testing in actual vehicles.
Introducing a New Generation of More Detailed and Informative Combustion Models
Authors: Bracco Frediano V.
Published: March 2023

The problem of modeling combustion within internal combustion engines is considered. A method is explained to evaluate the comprehensiveness, detail and predicting capability of a model. It consists of considering the equations for the most comprehensive and detailed model and in making successively more restrictive assumptions, thus getting progressively less detailed models. Particular attention is paid to the reasons for the assumptions, how they influence the accuracy of a model, and what basic information is missing. In so doing, the most detailed of the available models, and their predictive capabilities and limitations, are introduced. They include models for reciprocating and rotary engines, with uniform and stratified charges from dual carburetion and direct fuel injection. Examples of their results are given. One of them has been available since 1971, and another one is currently and fruitfully employed to aid the development of a production engine. Also introduced are more advance models presently under development and their applications. The equations of the most common and least detailed models are derived from the most general equations, thus evidencing their inherent limitations.
Further Aspects of Combustion Modelling in Spark Ignition Engines
Authors: James E. H.
Published: March 2023

An existing “phenomenological” computer model of the spark ignition engine combustion process has been used to reveal further information on flame development in such engines. A detailed flame map and pressure-time diagram (from Ref (6)) has been analysed to determine more precisely the 3-dimensional nature of the flame development across the CFR engine cylindrical disc combustion chamber. The conventional spherical flame assumption (centred at the spark plug) is found to be inaccurate with the extent of the deviation from sphericity varying with flame radius and compression ratio in both the vertical and horizontal (plan view) planes. The flame map provides input data in the form of enflamed volumes, heat transfer surface areas etc for the subsequent evaluation of turbulent burning velocities, mass burn rates, pressure-time diagrams etc. This is achieved by an iterative technique involving the mass burnt during any crank angle interval so that the burnt volume is correctly predicted (i.e. coincides with the known, measured, enflamed volume). A “thin flame” assumption appears valid across the major part of the chamber but, during the final “termination period”, combustion calculations involving finite burn-up rates in “thick” turbulent flames need to be incorporated. The transitional point coincides with a rapid escalation in the surface:volume ratio of the “end gas” and, possibly also, with the appearance of enhanced low frequency flow velocity fluctuations induced by piston motion on the expansion stroke. An exponential expression is used to portray mass burn rates within the entrained charge during flame propagation at this time. Pressure-time diagrams using the ‘thick’ flame model are compared with ‘thin’ flame predictions and measured values.

Authors: Dalley Amber , Kennedy Stephen , Ziegenfuss Audra
Published: March 2023

As AM technologies are being used with higher frequencywithin the automotive and aerospace industries, the interest in powder characterization and contaminant identification is growing—especially for suppliers looking to gain entry into these highly regulated industries. Standards for powder materials and methods used for aerospace applications are still be developed, and regulatory agencies such as the Federal Aviation Administration have been requesting that standards be developed as guidance for the industry. Methods such as CCSEM and HLS could be viable options for suppliers needing to adhere to a powder specification by demonstrating compliance. Solutions exist to integrate such methods into a production environment as exemplified by RJ Lee Group.

Authors: Okon B , A Ibom L , E Nsa E , Okoh O
Published: March 2023

A study was conducted to determine the nutritional potentials of some parts (corm and leaves) of swamp taro cocoyam (Cytosperma chamiIssonis) as a feed resource for livestock. The corm was prepared by washing in water before slicing into small pieces with sharp knife. The sliced corms were shared into two parts, one part sun dried for three days and the other part boiled and then sun dried for five days. Thereafter, the two parts were ground into powder separately with a mechanical blender, labeled and stored in different air-tight bottles. The leaves were washed, chopped into smaller pieces, sun dried, pulverized, labeled and stored. These stored samples were subjected to series of chemical analyses (proximate, phytochemical, mineral and vitamin determinations) to elucidate their chemical, toxicant, mineral and vitamin compositions. The results of proximate composition of the corm and leaves showed that the fresh leaves contained higher crude protein value (22.87t0.23 %), followed by raw sun dried corm (7.93+0.11 %). The fresh. leaves also contained higher crude fibre (6.73:0.01 %) than either the raw sun dried corm (1.36:0.05 %) or boiled sun dried corm (1.15+0.01 %). The boiled sun dried corm had the highest nitrogen free extract (NFE) or carbohydrate value (75.32+0.15 %), followed by the raw sun dried corm (74.31t0.05 %) and the fresh leaves (69.00t0.26 %). The dried leaves had the lowest NFE value (61.04:0.20 %). The results also showed that the leaves were richer in iron, flavonoid and alkaloid than the corm. In the contrary, the corm contained higher levels of phytate than the leaves. The results of vitamin and mineral determinations showed that the cocoyam leaves contained higher levels of evaluated vitamins (vit. A, riboflavin, niacin, thiamin and vit. C) than the corm. Besides, the leaves contained higher levels of magnesium, copper, potassium and iron than the corm, while the reverse is true for calcium, zinc, sodium and manganese. The statistical analyses for proximate composition between the fresh and dried leaves were significant (P<0.05) for CP, CF, ether extract, total ash and NFE. The analyses for these same fractions were not significant (P>0.05) between the raw sun dried and boiled sun dried corms. The analyses for mineral composition between the fresh and dry leaves, and between the raw sun dried and boiled sun dried corms were significantly (P<0.05) different for Cu, Mg, K, Na and Fe, but not for Zn, Ca and Mn. The analyses for vitamin composition between the fresh and dry leaves, and between the raw sun dried and boiled sun dried corms were significantly (P<0.05) different for riboflavin and vit. C, but not for niacin, thiamin and vit. A. The results of this study are indicative that the leaves and corm of swamp taro cocoyam are promising feed resources for livestock. It is therefore recommended that greater emphasis be placed on the production of swamp taro cocoyam because of its numerous benefits.
Multilocational evaluation of white yam genotypes using gge bi-plot methodology.
Authors: C Nwachukwu Emmanuel
Published: March 2023

Yams are Cultivated in diverse agroecologies and there is evidence of strong genotype and environment interaction. This has necessitated the evaluation of new yam genotypes in multi-locational trials. Five new white yam genotypes were evaluated in different locations of major yam producing areas; Umudike, Nsukka, Ubiaja, Abuja and Katsina-Ala, to test the performance and stability of these genotypes across the environments using GGE bi-plot software. The GGE bi-plot generated several graphic bi-plots which showed Umudike, Nsukka, Ubiaja and Katsina-Ala belonging to one mega- environment while Abuja and Ubiaja belong to another. The GGE bi-plot also showed the discriminating and non-discriminating environments. Katsina-Ala was the most discriminating environment while Nsukka was the least. A test environment that lacks discriminating ability lacks the capacity to provide information about the genotype being used. Such environment lacks usefulness and should be discarded as a test environment Katsina-Ala, with the longest vector is the most discriminating. This is followed by Ubiaja, Umudike and Abuja in that order. Nsukka is the least discriminating.

Published: March 2023

This paper evaluated the technical, allocative and economic efficiency of rubber- cassava intercrop system among smallholder rubber farmers in Edo Sate Nigeria through a survey of 160 rubber farmers in a multi stage purposive and simple random sampling techniques. Data collected were analyzed using budgetary techniques and stochastic frontier production function analysis. Budgetary analysis reveals an average total cos/ha of 93350. S583.44) with N169,560 (S1,059.75) accrues to the farmer as revenue and N76210(S476.31) as gross margin with a net farm income of N70,710(S441.94). The rate of return and return per capital invested were N1.82 and N0.82 showing both viability and profitability of rubber- cassava farming. The Maximum Likelihood Estimate (MLE) of the parameters of the stochastic frontier production function of the sampled farmers revealed that planting materials, agrochemicals, labour and farm size were significantly related with cassava output. The mean technical efficiency (TE) of respondents' was 0.82 with the scope of improving their efficiency by 18%. Education and extension contact were the significant factors that increase the technical efficiency of farmers. The estimates of the parameters of stochastic cost frontier also showed that the cost of planting materials, agrochemicals, depreciation, cost of labour and output were significantly related with cost of production with mean allocative efficiency (AE) of 0.67. Age, education, farming experience and extension contact enhance the allocative efficiency of rubber farmers. The economic efficiency index ranged from 0.18 to 0.85 with the mean of 0.55 indicating wide differentials between the least and efficient farmer with the scope of improving economic efficiency among rubber farmers by 45% in the short-run. Recommendations to improve efficient allocation of resources in a rubber cassava based farming system have been made in the study in the study.

Authors: Ekwok E , Achadu M , Ugar I , Udoh T , Akpan E , Ulem A
Published: March 2023

The Bornu Basin in northeast Nigeria was studied using high-resolution airborne magnetic data with the objective of improving the reliability of mapped magnetic and geothermal anomalies, and depth solutions. Necessary enhancement operations like analytic signal (ASIG), upward continuation, depth assessment methods involving standard Euler deconvolution (SED) and source parameter imaging (SPI) as well as spectral analysis applying the centroid technique were applied. The middle and southern parts are dominated by high frequency anomalies as revealed by the ASIG map. Furthermore, the magnetic data, when upward continued to 5 km, revealed avalanche of deeply buried igneous intrusions that created near-surface magnetic sources and geologic structures. Maximum thicknesses of sedimentary series estimated from SED and SPI, are respectively ~5974.7 and ~5885.3 m. These values correlate correlated relatively well with depth to the top boundary (Zt) of ~6550 m obtained from the centroid technique. These depth estimates reveal sequence of thick sediments overlying igneous intrusions and falls under the prospective geothermal anomaly zones characterised by high geothermal gradient (GG) (>55 °C/km) and heat flow (HF) (>130 mW/m2) values. Areas characterised by high geothermal anomalies correspond to igneous intrusion-dominated shallow Curie point depths (CPD or Zb).

Published: March 2023

Objective: Improving oral health knowledge is considered to be a prerequisite for oral health-related behaviour. The aim of this study is to determine the effectiveness of an oral health education package (OHE package) on oral health knowledge, attitude and practices of senior secondary school students. Methods: This is a quasi-experimental study where schools (experimental and control) were selected in Abakaliki urban area. Baseline data on oral health knowledge, attitude, and behaviour were collected from both groups with an intervention in the experimental group in the form of an OHE package but none in the control. Another set of data was collected from both groups after four months. Knowledge was rated high or low, attitude was rated good or poor, and behaviour was rated good or poor. Descriptive and inferential analyses were performed; while chi-square statistics and fisher exact tests were used for comparisons. The significance for all tests was set at ≤ 0.05. Results: Both groups had a good knowledge of oral health at baseline with significant improvements in the experimental group on all the knowledge questions following the OHE package (p < 0.05). Overall attitude in the experimental group improved by 68.1% (p = 0.000). Also, there were signs of progress in the behavioral assessments, however, the overall practice level of the experimental group increased marginally by 6.85% (p = 0.006).Conclusion: The OHE package improved the oral health knowledge, attitude, and behaviour of the participants considerably. There were positive behavioral outcomes although not commensurate with the level of attitudes improved. To consolidate the gains of this study, regular interventional programmes in the schools, which for emphasis, could be taken further into their curricula are recommended.

Published: March 2023

Background: Secondary school students are at a crucial stage in their life where decisions on oral health transit from the role of parents/guardians to their sole responsibility. Understanding factors that influence their oral healthcare practices is of paramount importance. Socioeconomic class (SEC) has been suggested to have a varied effect on oral health.Objective: To determine the effect of SEC on the oral healthcare practices and oral health status of secondary school students

Methods: The research was a descriptive cross-sectional study. Information collected via a self-administered questionnaire included socio-demographic characteristics, SEC, oral hygiene practices, dietary habits, oral healthcare utilization and oral health perception.

Results: A total of 370 students with mean age 15.0+1.44 participated in the study. SEC distribution was low class 32%, middle class 55%; high class 13%. There were significant associations between high SEC and twice-daily tooth brushing (p<0.05), frequent change of toothbrush (p<0.05), use of dental floss (p<0.05), consumption of carbonated drinks (p<0.05), low oral hygiene index score (p<0.05), high caries experience (p<0.005) and high oral healthcare utilization (p<0.05).

Conclusion: Higher SEC is associated with better oral hygiene and oral hygiene practices, poorer dietary habits and higher caries experience.
The STEAM vs STEM Educational Approach: The Significance of the Application of the Arts in Science Teaching for Learners' Attitudes Change
Authors: Okwara Valentine Ukachukwu , Henrik Pretorius Johan Pieter
Published: March 2023

This article critically examines existing literature on the importance of incorporating the arts into the teaching and learning of science subjects in schools. It explores the significance of the STEAM educational approach as an option in science teaching and learning that might provide a range of benefits to STEM learners. STEM is an acronym for Science, Technology, Engineering, and Mathematics while STEAM stands for Science, Technology, Engineering, Arts, and Mathematics. The argument in the article is focused on why leveraging such skills as creativity, problem-solving, critical thinking, communications, self-direction, initiative, and collaboration, which are inherent in the arts, to strengthen the effective teaching and learning of science within the STEAM educational context is important for STEM learners. The STEM educational approach to science teaching and learning employs an interdisciplinary approach to problem-solving aimed at equipping learners with 21st century skills such as critical thinking, creativity, problem-solving, self-direction, initiative, collaboration, effective communication, and morals. It also aims at providing them with the opportunity to apply these skills through the practices, contexts, and processes of hands-on activities. These are targeted at understanding science and viewing science differently, which might enable them to participate in a STEM-career pathway. However, the framework for STEM does not fully support an understanding that creativity can exist in science and that science can be taught in multiple ways, including application of the arts. STEAM, on the other hand, is grounded in a transdisciplinary approach to science teaching and learning. It explores the application of the arts in science teaching and learning. This is aimed at improving the confidence, attitudes, and interests of learners in science through new approaches to problem-solving which might strengthen positive attitudes towards science. This approach incorporates the common processes of science and arts, which includes discovery, observation, experimentation, description, interpretation, analysis, evaluation, wondering, visualising, exploring, and communication.
Theoretical Investigation of Diameter Effects and Edge Configuration on the Optical Properties of Graphdiyne Nanotubes in the Presence of Electric Field
Authors: Abdulkadhim T. M. J. , Alsaati S. A. A. , Shinen M. H.
Published: March 2023

In this research, the structural, electronic and optical properties of the armchair (ant) and zigzag (znt) Graphdiyne nanotubes (GDY-NT) with different diameters were studied based on density functional theory (DFT). The computations were done using SIESTA code, based on linear combination of localized atomic orbitals (LCAO) method and the generalized gradient approximation (GGA). The results from the band structure analysis show that all these nanotubes are semiconductor with direct band gap at gamma point. The band gap of the nanotubes is clearly dependent on the nanotube diameter, and by increasing the nanotube diameter, the band gap is decreased. Optical properties such as dielectric function; absorption coefficient, optical conductivity and refractive index were examined and calculated for all samples. The results show that all these functions have an inverse relationship with the nanotube diameter and a direct relationship with the band gap. The effect of applying the external electric field with intensity of 0.1 V/Å, 0.2 V/Å in the direction of x-axis (perpendicular to the nanotube axis) on the structural and electronic features of these nanotubes has been studied and calculated.

Published: March 2023

Curcumin analogues are widely used in numerous biological disciplines. They are widely employed in the pharmaceutical sector and offer good pharmacology application prospects in the present era. In the current study, two curcumin analogues—1,7-diphenylhepta-1,6-diene-3,5-dione (DPHDD) and 1,7-bis(3,4-dimethoxyphenyl)hepta-1,6-diene-3,5-dione (BDMPHDD)—were tested in vitro against the bacterial strain S. aureus. The testing demonstrated that the ligands may have antibacterial potential. The rule of five was used to pre-filter the compounds' drug-like characteristics prior to computer analysis. Then, to determine the mechanism by which the compounds limit the growth of S. aureus, molecular docking research was carried out using the AutoDock 4.2 tool. Six distinct target proteins from S. aureus were chosen for this purpose (PDB ID: 1T2P, 3U2D, 2W9S, 1N67, 2ZCO, and 4H8E). The target protein Dihydrofolate reductase enzyme (PDB ID: 2W9S) and Staphylococcus aureus sortase-A (PDB ID: 1T2P) demonstrated a good binding affinity for the two analogues, (BDMPHDD) & (DPHDD) respectively.Due to the inactivation of these enzymes, the substances 1,7-diphenylhepta-1,6-diene-3,5-dione (DPHDD) and 1,7-bis(3,4-dimethoxyphenyl)hepta-1,6-diene-3,5-dione (BDMPHDD) exhibit significant growth-inhibitory potential against S. aureus.

Ao fim, são realizadas considerações sobre o cenário de enfrentamento à emergência climáticas no Brasil. Conclui-se que o Brasil não está realizando um enfrentamento efetivo às mudanças climáticas e se defende a necessidade urgente que o país planeje e execute ações que visem não só a mitigação das mudanças climáticas com a redução da emissão de gases do efeito estufa, mas também a adaptação de sua sociedade aos riscos dos efeitos irreversíveis por elas causados, de acordo com os compromissos assumidos internacionalmente. Igualmente, defende-se que o Estado brasileiro deve ampliar suas capacidades de desenvolvimento de projetos financiados através dos mecanismos internacionais previstos no âmbito da Convenção Quadro das Nações Unidas sobre a Mudança do Clima.
Pagar condenações judiciais desequilibra o orçamento público?
Authors: Mascarenhas Caio Gama
Published: March 2023

O objetivo desse artigo é discutir se as Emendas Constitucionais 113 e 114 mantêm-se fiéis aos propósitos originais do “Novo Regime Fiscal” da EC 95/2016 ao submeterem o pagamento de precatórios federais ao teto de gastos. A primeira parte do artigo trata sobre o teto de gastos no texto constitucional em sua forma originária (EC 95/2016): do que se trata? Qual era o seu propósito original? A segunda parte diz respeito aos aspectos contextuais e normativos das Emendas Constitucionais 113/2021 e 114/2021. A terceira e quarta partes dizem respeito ao regime financeiro-orçamentário dos precatórios. A quinta parte trata do julgamento do Supremo tribunal Federal sobre a Emenda Constitucional n. 62/2009, que contingenciou pagamento de precatórios. A sexta e última parte cuida da pergunta principal: “Pagar condenações judiciais desequilibra o orçamento?”. Utilizam-se neste último tópico doutrinas nacionais e internacionais sobre equilíbrio orçamentário e sustentabilidade fiscal. O trabalho é desenvolvido a partir dos métodos indutivo e dedutivo utilizando de material bibliográfico e documental. Por se tratar de um estudo descritivo e exploratório, é realizado com base na pesquisa bibliográfica e documental, utilizando-se por vezes do método dedutivo e, outras vezes, do indutivo, principalmente nas críticas e reflexões acerca da doutrina, estudos e textos normativos.

Published: March 2023

In this study, the antimicrobial activity of neutral electrolyzed water (NEW) on Bacillus cereus forming endospore, Escherichia coli and, toxin producer Aspergillus flavus and Penicillium expansum was determined both on the surface of steel plates in the presence of organic matter artificially inoculated and in cell suspensions. Also, the antimicrobial efficiency of NEW was compared to that of Sodium hypochlorite (NaClO). Experiments were carried out at room temperature (22 °C). 1% sodium hypochlorite solution (with 531 ppm free chlorine), and different concentrations of NEW, 5% (with 63 ppm free chlorine), 10% (with 120 ppm free chlorine), and 15% (with 187 ppm free chlorine) were used for the comparison. Cell suspensions and stainless-steel plates inoculated with a final 10% liquid fig solution were treated with NEW and NaClO for 0 (untreated, control), 15, 30, and 60 seconds. Then, viable cell counts both in cell suspensions and on the inoculated stainless-steel plates were determined. It was determined that there were significant differences (P
Compulsão alimentar, resistência à insulina e incidência de diabetes tipo 2: resultados do Estudo Longitudunal de Saúde do Adulto (ELSA-Brasil)
Authors:   , Silva Mayara Dias Parreiras da

A compulsão alimentar é caracterizada pelo consumo de uma grande quantidade de alimentos, em um curto período de tempo, associado a sensação de perda de controle em relação ao que e quanto se come. O diabetes tipo 2 (DM2) é um dos maiores desafios de saúde pública do século XXI, e, por isso, identificar seus fatores de risco é um importante caminho para o controle da doença. Evidências apontam para um possível papel desse comportamento na diminuição da sensibilidade à insulina e consequente desenvolvimento do DM2, mas estudos longitudinais sobre o tema ainda são escassos e com resultados inconclusivos. Dessa forma, o objetivo desta pesquisa foi investigar a associação do comportamento de compulsão alimentar com a prevalência de resistência à insulina (RI) e incidência de DM2 em uma coorte de servidores públicos. Foram utilizados dados da linha de base (2008-2010; n=14.593) e da onda 2 (2012-2014; n=11.464) de participantes do Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil). A exposição foi a presença de compulsão alimentar na linha de base, avaliada por uma questão desenvolvida a partir dos critérios propostos para investigação no DSM-IV. Como desfecho, tem-se a prevalência de RI na linha de base, avaliada por meio do modelo de avaliação da resistência à insulina (HOMA-IR) e do índice triglicerídeos-glicose (TyG), e a incidência de DM2 entre a linha de base e a onda 2, avaliada por meio do autorrelato de diagnóstico médico e exames bioquímicos. As associações foram testadas por meio de modelos de regressão de Poisson, com variância robusta, brutos e ajustados por potenciais confundidores. Como resultados, na onda 1, a prevalência de compulsão alimentar foi de 15,3%, dos quais 67,2% e 30,6% apresentaram RI pelos índices HOMA-IR e TyG, respectivamente. Nos modelos ajustados, indivíduos com compulsão alimentar apresentaram maior prevalência de RI comparados àqueles que não apresentaram esse comportamento (HOMA-IR: RP = 1,29 e IC95% = 1,25 - 1,34 e TyG: RP = 1,29 e IC95%=1,21 - 1,38). Na onda 2, a incidência de DM2 foi de 7,4% e a prevalência de compulsão alimentar foi de 14,6%. Nos modelos ajustados, indivíduos com compulsão alimentar apresentaram maior risco de DM2 incidente comparados àqueles com ausência desse comportamento (RR= 1,21 e IC95% = 1,01 - 1,44). Essa associação perdeu significância após o ajuste pelo IMC (RR = 0,96 e IC95% = 0,81 - 1,14). Em conclusão, esses resultados reforçam que o comportamento de compulsão alimentar se mostra prevalente na população adulta e relaciona-se como um fator de risco a desfechos metabólicos, como a RI e o DM2.

Patrimônio cultural e identidade: os processos de patrimonialização dos bens piranguenses e os desafios da preservação e da conscientização
Authors:   , Dias Danielly Meireles
Published: March 2023

Este estudo trata dos processos de patrimonialização acerca dos bens patrimoniais de Piranga, MG. Buscamos compreender a relação entre patrimônio, identidade, pertencimento e preservação. A metodologia utilizada foi um levantamento sobre a história da cidade por meio de bibliografia existente, fontes documentais e de uma análise dos documentos que integram esses processos e os dossiês de tombamento. Para tanto, realizamos uma discussão acerca da população piranguense e sobre como ela se identifica com esses bens patrimoniais, tendo como objetivo analisar se a população faz parte desses processos e se o preservar é uma demanda popular ou não. Como recorte temporal, analisamos os processos de tombamento que datam de 1959 a 2009 e os inventários que datam até 2011. Procuramos, por meio desse levantamento e do contato com os agentes relacionados, descobrir se há uma identificação dos moradores com o patrimônio cultural local, com o intuito de tentar entender se o descaso com vários bens é uma consequência da não identificação da população com o patrimônio ou não. Assim, foi possível elucidar qual a importância da relação entre memória, identidade e pertencimento acerca da questão patrimonial no caso específico da cidade mineira de Piranga. Palavras-chave: Patrimônio. Piranga. Piranguense. Dossiê. Tombamento. Patrimonialização.
Aktiviti Pembangkang di Parlimen Ke-13, 2013-18
Authors: Asri Amirul Azam , Muhamad Rosyidah Bt
Published: March 2023

Pemimpin dan kepimpinan terbentuk di dalam semua organisasi sama ada secara formal atau tidak formal. Konsep pemimpin dan kepimpinan juga tidak dapat dipisahkan dengan sistem politik di sesebuah negara. Konsep pemimpin dan kepimpinan digunakan secara meluas terhadap pelbagai cabang ilmu seperti ekonomi, sosiologi, agama, pengurusan, sains politik dan sebagainya (Malike, 2014). Namun, setiap bidang atau cabang ilmu memberi konsep yang berbeza tentang pemimpin dan kepimpinan mengikut perspektif bidang itu sendiri. Dalam bidang politik pula, konsep kedua-duanya ditekankan tentang kuasa, pemerintahan dan demokrasi. Parti politik merupakan bentuk asas kepada sebuah masyarakat demokrasi. Dalam sistem demokrasi berparlimen khususnya Malaysia, peranan ahli Parlimen tidak hanya di dalam parlimen atau kabinet. Dalam parlimen, wakil rakyat tidak hanya mewakili suara rakyat sahaja namun turut mewakili kepentingan parti politik yang disertai. Di Malaysia, peranan ahli Parlimen tidak dinyatakan secara bertulis. Maka setiap pihak akan memahami konsep itu dengan perspektif masing-masing. Artikel ini akan membincangkan tentang aktiviti pembangkang dalam parlimen. Selain itu, artikel ini turut memberi penumpuan yang khusus terhadap tingkah laku pembangkang di parlimen bagi mengenal pasti tingkah laku yang aktif atau pasif. Artikel ini juga akan menganalisis aktiviti-aktiviti pembangkang dalam parlimen ketika sesi Pertanyaan kepada Menteri (PkM) dan sesi usul. Kedua-dua aktiviti ini digunakan sebagai sumber untuk mengumpul data. Hal ini kerana, aktiviti-aktiviti tersebut dilihat signifikan dengan peranan pembangkang.
Effect of International Financial Reporting Standards Compliance on Financial Reporting Quality: Evidence from a Developing Country
Authors: Kabwe Martin
Published: March 2023

Purpose: Despite global adoption of International Financial Reporting Standards to improve financial reporting quality, there is still inconclusive and limited empirical evidence of improving financial reporting quality especially from developing countries. Therefore, the study analysed the relationship between International Financial Reporting Standards compliance and Financial Reporting Quality from an African country perspective.

Methodology: Financial Reporting Quality was measured using measurement tool developed by the Nijmegen Center for Economics and International Financial Reporting Standards compliance was measured using dichotomous and partial compliance methods. Study period was 2012 to 2018 involving 20 Zambian listed companies. Study involved panel data analysis and hence, Hausman test was conducted to select the model. Multiple linear regression was used as a data analysis method.

Findings: The results indicated a statistically insignificant relationship between International Financial Reporting Standards compliance and Financial Reporting Quality. Therefore, the implication of the study is that the adoption of International Financial Reporting Standards does not influence financial reporting quality among Zambian listed companies. The low compliance with International Financial Reporting Standards among the listed may have contributed.

Unique Contribution to Theory, Practice and Policy: This is first study in Zambia looking at the influence of IFRS Compliance on Financial Reporting Quality and therefore, contributes to the extant empirical studies analysing whether IFRS compliance influences the financial reporting quality given the mixed results across.
