Published: December 2023

The object of the research is machine shelling efficiency. This study focused on the assessment of a fabricated corn Sheller machine and resolution of optimal moisture content percentage dry basis (% MCdb) for shelling corn-cobs. Corn-cobs samples at 8, 13 and 18 % MCdb were sorted into 3.15, 2.15 and 1.15 kg feed-masses, respectively. Samples were selected in triplicates for shelling operations time 5, 6 and 7 seconds. Standard method was used to determine the effect of shelling operation on corn-cobs’ quality variables. Response Surface Method was employed to optimize data with machine feed-mass and moisture content as independent variables, whilst responses being: shelled, un-shelled, damaged, un-damaged corn grains, as well as grain breakage ratio, machine shelling efficiency and shelling process time. The data gotten from the results were utilized to evaluate the corn-cob shelling machine and were analyzed using ANOVA at 95 % confidence interval. Corn-cobs 8 % MCdb shelled at 5 seconds and machine feed mass of 3.15 kg had the highest shelling efficiency of 97.78 %, followed by 13 % MCdb, feed mass of 2.15 kg, machine shelling efficiency 92.06 %; shelled in 6 seconds, lastly, 18 % MCdb, feed mass of 1.15 kg, shelling efficiency was 87.82 % shelled in 6 seconds. The resultant recorded response masses; shelled, un-shelled, damaged corn grain (kg) and grain breakage ratio recorded were at lower values. At lower machine shelling time, feed mass and moisture content percentage (% MCdb) of the corn cobs, higher shelled grains off the corn-cobs were recorded with reduced damaged grains, indicating higher shelling efficiency of the fabricated corn-cob Sheller machine.

Authors: Divya Kothandaraman , Indhira Kandaiyan 
Published: December 2023

This research delves into the dynamics of a retrial queueing system featuring heterogeneous servers with intermittent availability, incorporating feedback and working vacation mechanisms. Employing a matrix geometric approach, this study establishes the steady-state probability distribution for the queue size in this complex heterogeneous service model. Additionally, a range of system performance metrics is developed, alongside the formulation of a cost function to evaluate decision variable optimization within the service system. The Artificial Bee Colony (ABC) optimization algorithm is harnessed to determine service rates that minimize the overall cost. This work includes numerical examples and sensitivity analyses to validate the model's effectiveness. Also, a comparison between the numerical findings and the neuro-fuzzy results has been examined by the adaptive neuro fuzzy interface system (ANFIS).
A NEW CHARACTERIZATION OF SYMMETRIC DUNKL AND \(q\)-DUNKL-CLASSICAL ORTHOGONAL POLYNOMIALS
Authors: Habbachi Yahia 
Published: December 2023

In this paper, we consider the following \(\mathcal{L}\)-difference equation$$\Phi(x) \mathcal{L}P_{n+1}(x)=(\xi_nx+\vartheta_n)P_{n+1}(x)+\lambda_nP_{n}(x),\quad n\geq0,$$where \(\Phi\) is a monic polynomial (even), \(\deg\Phi\leq2\), \(\xi_n,\,\vartheta_n,\,\lambda_n,\,n\geq0\), are complex numbers and \(\mathcal{L}\) is either the Dunkl operator \(T_\mu\) or the the \(q\)-Dunkl operator \(T_{(\theta,q)}\). We show that if \(\mathcal{L}=T_\mu\), then the only symmetric orthogonal polynomials satisfying the previous equation are, up a dilation, the generalized Hermite polynomials and the generalized Gegenbauer polynomials and if \(\mathcal{L}=T_{(\theta,q)}\), then the \(q^2\)-analogue of generalized Hermite and the \(q^2\)-analogue of generalized Gegenbauer polynomials are, up a dilation, the only orthogonal polynomials sequences satisfying the \(\mathcal{L}\)-difference equation.
Predictive power of the Geriatric Nutritional Risk Index for mortality in patients over 80 years of age undergoing open heart surgery
Authors: ÇOBAN Özgür , UÇAK Hacı Ali 
Published: December 2023

Purpose: This retrospective study aimed to determine the predictive power of the geriatric nutritional risk index, calculated using the preoperative albumin value of patients over 80 years old who underwent open-heart surgery, in relation to the postoperative mortality rate.
Materials and Methods: A total of 22 patients (13 males, 9 females; mean age: 82.1±2.4 years; range, 80-88 years) who underwent open elective heart surgery for coronary bypass and heart valve replacement between July 2019 and September 2022 were retrospectively analyzed using the geriatric nutritional risk index. Based on this index, two distinct groups were formed. Values 98 and below were considered risky, and values 99 and above were considered risk-free. There were 6 patients in the risk group. The other 16 patients were in the risk-free group. All patient groups were compared on the basis of surgical procedures, age, gender, body mass index (kg/m2), diabetes, hypertension, atrial fibrillation, smoking, and operative characteristics.
Results: In the study, 6 risky (27.3%) and 16 risk-free (%72.7) patients were examined according to the geriatric nutritional risk index and the mortality rate was found to be high (%66.7) in the risky group. The patients in the risk group had lower body mass index and albumin values (25.0±1.8 and 30.1±2.4) compared with the risk-free group (28.1±2.4 and 36.7±3.1). In addition, the mean extubation values were high (11.2±4.2). No significant difference was found between the other parameters and the presence of risk.
Conclusion: Before undergoing open heart surgery, the Geriatric Nutritional Risk Index can strongly predict postoperative mortality rates.
Ensemble Region-Specific GMMs for Subduction Earthquakes
Authors: Sedaghati Farhad , Pezeshk Shahram 
Published: December 2023

Abstract
This study develops data-driven global and region-specific ground-motion models (GMMs) for subduction earthquakes using a weighted average ensemble model to combine four different nonparametric supervised machine-learning (ML) algorithms, including an artificial neural network, a kernel ridge regressor, a random forest regressor, and a support vector regressor. To achieve this goal, we train individual models using a subset of the Next Generation Attenuation-Subduction (NGA-Sub) data set, including 9559 recordings out of 153 interface and intraslab earthquakes recorded at 3202 different stations. A grid search is used to find each model’s best hyperparameters. Then, we use an equally weighted average ensemble approach to combine these four models. Ensemble modeling is a technique that combines the strengths of multiple ML algorithms to mitigate their weaknesses. The ensemble model considers moment magnitude (M), rupture distance (Rrup), time-averaged shear-wave velocity in the upper 30 m (VS30), and depth to the top of the rupture plane (Ztor), as well as tectonic and region as input parameters, and predicts various median orientation-independent horizontal component ground-motion intensity measures such as peak ground displacement, peak ground velocity, peak ground acceleration, and 5%-damped pseudospectral acceleration values at spectral periods of 0.01–10 s in log scale. Although no functional form is defined, the response spectra and the distance and magnitude scaling trends of the weighted average ensemble model are consistent and comparable with the NGA-Sub GMMs, with slightly lower standard deviations. A mixed effects regression analysis is used to partition the total aleatory variability into between-event, between-station, and event-site-corrected components. The derived global GMMs are applicable to interface earthquakes with M 4.9–9.12, 14≤Rrup≤1000  km, and Ztor≤47  km for sites having VS30values between 95 and 2230 m/s. For intraslab events, the derived global GMMs are applicable to M 4.0–8.0, 28≤Rrup≤1000  km, and 30≤Ztor≤200  km for sites having VS30 values between 95 and 2100 m/s.

Resumo: Este artigo tem como objetivo identificar a presença das ideias de Cicero, o cônsul romano, nos escritos políticos da Restauração de Portugal. A Restauração de Portugal pode ser identificada como um movimento que recuperou a autonomia política do reino lusitano em 1640 com a defenestração de Miguel de Vasconcelos, o secretário de Estado de d. Filipe IV, coroando d. João IV como rei de Portugal e colocando fim ao domínio do reino castelhano sobre os portugueses existente desde 1580. O movimento que culminou na Restauração de Portugal contou com uma forte estrutura de publicação de textos favoráveis ao movimento e ao governo de d. João IV. Entre as figuras que recuperaram os textos de Cicero em suas argumentações favoráveis ao novo governo, destacam-se os repúblicos, agentes do período comprometidos com a conservação do bem comum de Portugal.

Blood stream infections (BSIs) occur more frequently in patients hospitalized in Intensive care units (ICUs). Intravascular devices are the most frequent predisposing factor causing BSI. To compare the proportion, risk factors, microbiological profile of Blood stream Infections and Central line associated bloodstream infection in Cardiology Intensive care units (CICU) and Cardiothoracic Intensive care units (CTICU).This is a prospective study conducted by the Dept. of Microbiology along with Cardiology Intensive care unit(CICU), and Cardiothoracic Intensive care unit (CTICU) of a tertiary care centre, from June 1st 2017-Oct 312018.Laboratory confirmed BSIs (LCBSI’s), occurring more than 48hrs after ICU admission were included in the study. Identification of pathogens were done by standard methods.A total of 1640 blood cultures were analyzed (CICU=890,CTICU=750).73 Primary BSIs were observed with male preponderance.68/73 diagnosed to have non CLABSI (CTICU=35/68 51.4%, CICU=33/68, 48.5%) and 5/73 cases diagnosed to have CLABSI (CTICU=5/73, 6.84% CICU=0%) 47.94% of our isolates were Gram negative pathogens with as the predominant followed by 35.6% of Gram positive with as the major pathogen & 16.4% were Candida spp. 20.5% were multi drug resistant and 10% were ESBL producers. Prevalence and incidence rates were high in CTICU (5.3% & 1.5%) compared to CICU (3.7% & 0%) of BSI & CLABSI respectively.BSI is preventable costly complication that occur with greater frequency in the ICU settings. Strict adherence to Infection control measures such as hand hygiene, aseptic precautions during blood culture collection and bundle care measures can decrease the BSI and CLABSI incidence rates.
The Power of Judgement regarding Covid-19 policies or practices. A reflection from New Zealand
Authors: Gray Ben 
Published: December 2023

Judgements are made when problems are complex and there is insufficient information or too many competing factors for a protocol or guideline to be helpful. Judgements inevitably reflect values and beliefs of what is good. They are based on an ethical foundation. A particular ethical issue relevant to Covid-19 is inequality of health outcomes. Making a judgement is of little moment if the person making the judgement is not trusted by anyone else. An understanding of trust is important. Many judgements that impacted on the outcome of Covid-19 were made in the years before the pandemic. Judgements on the science underlying decisions should be made by the specialists in that area o science. It is important to be clear for whose benefit a judgement is made. Is it for the individual, for a particular community, a particular country or for the whole world? In the case of Covid-19 a decision made that did not at least consider the impact on the rest of the world was likely to be flawed, given that the pandemic is a global problem needing a global approach. Judgements during a novel pandemic are by definition made on insufficient information. To mitigate this, they need to be made transparently, clearly enunciating the reasons for the judgement, based on as much consultation as possible and trying to avoid unconscious bias. This has been an existential crisis for us all. We need to make judgements differently in the future or we risk this disaster being repeated.

Authors: McGarry Jacqueline 
Published: December 2023

Within this article we reflect on the Belfast Health and Social Care Trust (BHSCT) Workforce Learning Development Improvement Service’s response to Covid19, and the need to support social work students commencing their Practice Learning Opportunity/placement (PLO) within Adult Services in August 2020. It was recognised that the global response to the Covid19 pandemic generated a landscape of significant change and innovation for both the Workforce Learning Development and Improvement Service within the Belfast Health and Social Care Trust (BHSCT) and students who were due to commence their PLOs within BHSCT for a period of practice learning from August – December 2020. The article explores how the Workforce Learning Development Improvement Service across in Adult Services within the BHSCT responded to meet changing need for social work students, BHSCT practice teachers (practice educators) and the operational context within which social workers practiced. The initiative, now consolidated within the student experience of their Practice Learning Opportunity (PLO) within BHSCT, is audited annually, and this article explores the learning from the initial audits in December 2020 and June 2021, as well as the ongoing changes embedded within the teams as we emerge from the Covid19 pandemic.

Розглядається питання побудови емпіричних формул. Порівнюються теоретичні формули, які використовуються в довідниках і регресійні моделі, отримані за результатом експерименту. Показано, що, хоча в цілому для грубих оцінок теоретичні формули відповідають експериментальним даним, але точність опису незадовільна для якісного і надійного прогнозу.
Структура зв’язків теоретичної формули не відповідає ні експериментальним даним, ні системним положенням.
Для отримання науково обґрунтованих емпіричних формул необхідно користуватись теорією планування експериментів і регресійним аналізом.

The question of construction of empirical formulas is considered. The theoretical formulas used in reference books and regression models obtained as a result of the experiment are compared. It is shown that, although in general for rough estimates the theoretical formulas correspond to experimental data, but the accuracy of the description is unsatisfactory for a qualitative and reliable forecast.The relationship structure of the theoretical formula does not correspond to either experimental data or systemic provisions.To obtain scientifically sound empirical formulas, it is necessary to use the theory of experimental design and regression analysis.
