Main Objective: To document clinical characteristics and outcomes of patients admitted with bronchiolitis at the Children's Hospital, Harare March 2018 to February 2019.
Study Design: A hospital based analytical cross sectional study.
Study Setting: The study was conducted at the Children's Hospital, Sally Mugabe Hospital.
Materials and Methods: Children aged 2months to 2 years hospitalised with bronchiolitis Results: A total of 206 children were recruited. Mean age was 5.4 (SD ±4.3) months with 148 (72%) less than six months. The male to female ratio of 1.8:1. Only 15% of the children were born preterm (85%). The main symptoms were cough (91%), rhinorrhoea (69%) and hot body (66%). Thirteen percent had a comorbid condition. Physical examination findings were mainly tachypnoea (89%) and hypoxia (83%). A severe modified Tal (mTal) score was noted in 116(56%) children at admission and 51(25%) still had a severe mTal score when repeated within 12 hours of admission. The median length of hospital stay was 4 days (IQR 3; 6) and 90(44%) children had a prolonged stay (>4 days). Only 3 (1.5%) children died. A high repeat mTal score, wasting, hypoxia and expiratory/inspiratory wheezes, were associated with a prolonged hospital stay. (p= 0.025, p= 0.004, p=0.001, p= 0.007 respectively).
Conclusion: Majority of children admitted with bronchiolitis were less than 6 months of age. There was a male predominance. Bronchiolitis causes high morbidity but low mortality in children from this low-income setting.
Public key exponent attacks on multi-prime power modulus using continued fraction expansion method
Authors: Ibrahim Zaid , Shehu Sadiq , Abubakar Saidu I. 
Published: January 2023

This paper proposes three public key exponent attacks of breaking the security of the prime power modulus 𝑁=𝑝2𝑞2 where 𝑝 and 𝑞 are distinct prime numbers of the same bit size. The first approach shows that the RSA prime power modulus 𝑁=𝑝2𝑞2 for q<𝑝<2q using key equation 𝑒𝑑−𝑘𝜙(𝑁)=1 where 𝜙(𝑁)= 𝑝2𝑞2(𝑝−1)(𝑞−1) can be broken by recovering the secret keys 𝑘 /𝑑 from the convergents of the continued fraction expansion of e/𝑁−2𝑁3/4 +𝑁1/2 . The paper also reports the second and third approaches of factoring 𝑛 multi-prime power moduli 𝑁𝑖=𝑝𝑖2 𝑞𝑖2 simultaneously through exploiting generalized system of equations 𝑒𝑖𝑑−𝑘𝑖𝜑(𝑁𝑖)=1 and 𝑒𝑖𝑑𝑖−𝑘𝜑(𝑁𝑖)=1 respectively. This can be achieved in polynomial time through utilizing Lenstra Lenstra Lovasz (LLL) algorithm and simultaneous Diophantine approximations method for 𝑖=1,2,…,𝑛.

In this research, zinc oxide nanoparticles (ZnO-NPs) were synthesized by simple solution-based approach using zinc nitrate [Zn(NO3)2.6H2O] and sodium hydroxide (NaOH) as precursor. The Synthesized ZnO-NPs were characterized by XRF, XRD and TGA methods. XRD method confirmed the formation of nanosized zinc oxide particles in the size range of 13–47 nm. XRF and TGA were used to determine the elemental composition and thermal stability of ZnO-NPs, respectively. The ZnO-NPs were used as catalyst in the production of biodiesel from waste frying oil (WFO) via transesterification method. The transesterification process yielded 97.8 % (w/w) WFO biodiesel. The results of the fuel properties revealed that, all the parameters tested are within the ASTM limits, indicating that the biodiesel produced could be used as an alternative diesel fuel.
Periodic Point as a Recurrent Formation Using the Logistic Function: A Survey

Published: January 2023

In topological dynamical systems (TDS), recurrence (periodic–like recurrence) is one of the important concepts in its studies but one major problem is the inability to demonstrate and/or illustrate its formation in the orbit structure of system from a topological point of view. In this paper, the logistic function was applied to demonstrate the periodic point as a recurrent formation (periodic–like recurrence) in the topological dynamical system and dynamical system. The Wolfram Alpha computational knowledge engine was used in obtaining the tables and the figures for the study through various examples of the logistic function. The study shows that period – 2 recurrence is formed when the trajectory of the function is made up of two different values that keep repeating after successive iterations as a result of the period – 2 orbits when the parameter of the function is between 3 and 3.45. The study again shows that when the parameter of the function is greater than 3.83 there is a period – 3 point hence the formation of other periodic points. Convincingly, beyond this period – 3 is another subsequent period called the period-doubling cascade leading into chaos. This period-doubling asserts that other periodic–like recurrences are also present, hence period –n recurrent exists.

Published: January 2023

O dimensionamento de uma trasmissão mecânica envolve vários aspectos. Vai desde a escolha do material a ser utilizado na fabricação dos eixos até o tipo de transmissão a ser usada. Uma transmissão de veículo off-road deve suportar os impactos da prova, portanto, deve ser robusta. Deve também atender as solicitações da prova de potência e, principalmente, de torque. Conforme o projeto da suspensão, o eixo-árvore responsável por transmitir o movimento da caixa de engrenagem até a roda é também parte da suspensão, ou seja, será responsável por suportar todo o peso da parte traseira do automóvel. Sendo assim, deverá ser um eixo robusto, calculado para suportar não só á flexão resultante da rotação e potência mas também quando à flexão que sofrerá por ter atuando em si parte da estrutura. A escolha do materila do eixo de trasmissão de um mini-baja passa por um ponto importante no que se diz respeito a competições de alto nível: peso. Comprovadamente, veículos mais leves têm melhor desempenho nas competições automobilísticas, sendo que a relaçõa peso-potência é primordial, ainda mais considerando a pouca potência fornecida pelo motor padrão da competição, 10cv. Sendo assim, o mais indicado é se utilizar um alumínio duro, com tensão de escoamento alta, para se fabricar o eixo de trasnmissão. Para veículos, o mais usual são engrenagens helicoidais, por seu baixo ruído e baixo nível de vibração. Para tal dimensionamento utilizam-se as normas DIN 867 e DIN 3969. Para o dimensionamento considerando os grandes choques ocorridos durante a competição quanto o cuidado com o peso final, nos leva a compreender que mais do que se utilizar o usual dentro da indústria, é necessário estar atento aos caminhos alternativos que possam gerar resultados melhores.

Problem. Alcohol addiction is an important problem for both society and healthcare. A lot of scientific research on the problems, conse-quences and treatment of alcohol consumption has been carried out in the world and in Lithuania, but there is a lack of deeper analysis of personal experiences related to the motivation of addicted persons, their opinion about treatment and needs.
Aim of the study is to assess the motivation for sobriety of alcohol-dependent persons.
Methods. A qualitative study was conducted using a semi-structured interview and analyzing the data using the qualitative content analysis method. The study participants are 6 alcohol-dependent persons who continue treatment in the psychosocial rehabilitation department during the study.
Results and Conclusions. Based on the statements of the participants in the study, it was found out that it was not easy for the respondents to give up alcohol: they distanced themselves from friends who drank alcohol, they felt awkward and stupid when they had to explain why they did not drink, it was unpleasant to see drunken friends with sober eyes, it was difficult to figure out what to do, especially on weekends. The participants decided to pursue sobriety based on external and internal motivation. External motivating factors family members, relatives, colleagues, lost work and property; internal - deteriorated health, relationship problems in the family, stigmatizing society's attitude, self-loathing.

Cloud-radiative impact on the dynamics and predictability of an idealized extratropical cyclone
Authors: Keshtgar Behrooz , Voigt Aiko , Hoose Corinna , Riemer Michael , Mayer Bernhard 
Published: January 2023

Abstract. Extratropical cyclones drive midlatitude weather, including extreme events, and determine midlatitude climate. Their dynamics and predictability are strongly shaped by cloud diabatic processes. While the cloud impact due to latent heating is much studied, little is known about the impact of cloud radiative heating (CRH) on the dynamics and predictability of extratropical cyclones. Here, we address this question by means of baroclinic life cycle simulations performed at a convection-permitting resolution of 2.5 km with the ICON model. The simulations use a newly implemented channel setup with periodic boundary conditions in the zonal direction. Moreover, the simulations apply a new modeling technique for which only CRH interacts with the cyclone, which circumvents changes in the mean state due to clear-sky radiative cooling that has complicated the interpretation of previous work. We find that CRH increases the kinetic energy of the cyclone system. The impact is most prominent at upper levels. To understand the CRH impact on the upper-tropospheric circulation, we diagnose the evolution of differences in potential vorticity between a simulation with and without CRH, and we quantify through which processes these differences grow over the course of the cyclone's life cycle. According to this diagnostic, CRH affects the cyclone mostly via the intensification of latent heating from cloud microphysical processes. Near the tropopause, direct diabatic modification of potential vorticity by intensified latent heat release precedes further changes in the tropopause by the upper-tropospheric divergent flow, which represents an indirect impact of latent heat release. Subsequently, differences in the tropopause structure amplify with the rotational flow during the highly nonlinear stage of the baroclinic wave. Our results show that although CRH is comparably small in magnitude, it can affect extratropical cyclones by changing cloud microphysical heating and subsequently the large-scale flow. The CRH impact follows a previously identified mechanism of multi-stage upscale error growth. At the same time, simulations in which CRH is disabled after certain days show that the CRH impact operates throughout the entire intensification phase of the cyclone. This means that CRH does not merely provide an arbitrary initial perturbation to the cyclone, from which differences grow in a generic way. Instead, our results suggest that uncertainties associated with the representation of CRH in numerical models have a more systematic impact and may more fundamentally influence model predictions of extratropical cyclones.

Likinge: Julian of Norwich’s Theology of Pleasure
Authors: Millay Thomas J. 
Published: January 2023

ABSTRACT
This article argues for the centrality of a neglected theme in the writings of Julian of Norwich: pleasure. To argue for the theme’s centrality, the author focuses on Julian’s Short Text, A Vision Showed to a Devout Woman. In the expanded Long Text, there are themes added unto pleasure; however, Julian’s theology of pleasure remains fundamental to the dynamic of the text. Looking at the Short Text enables us to see how the theme is established. When one pays attention to pleasure (or, in Julian’s English, likinge), its importance to the text is remarkable. In fact, the author argues that the transformation of pain into pleasure is a motif that is basic to Julian’s whole visionary experience. Characteristically, she also orchestrates a theology around the theme, connecting pleasure to God’s relation to human beings, the intertrinitarian relations, and how human beings are supposed to relate to themselves. In short: once this theme is highlighted, a rich theology of pleasure reveals itself.

Published: January 2023

Abstract
Modern pedagogy proposes constant changes in educational purposes and approaches based on the specific needs of students and individual learning styles. This condition separates traditional educational models from new innovative and creative models strengthened by the use of digital technologies and tools. The present investigation carries out a qualitative and quantitative analysis of the Flipped Classroom model, the benefits and procedures for its application from teaching as teaching strategies and from the student's point of view as a motivating model where he actively participates in the construction of knowledge and improvement of the academic performance as a result of its proper application.
