A Comparative Study on Winterfield 2512-G61 and Winterfield-2512 IBDV Immune-complex Vaccines in Commercial Broiler Chickens

Infectious bursal disease (IBD) is a very dangerous immunosuppressive disease affecting poultry production worldwide. The good vaccination program that can overcome the maternal derived antibodies (MDA) in young chicks is the main method to control this disease. In this study, the immunogenicity and protective efficacy of two IBDV immune-complex (ICX) vaccines were evaluated against challenge with very virulent IBDV. A total of 240-day-old commercial broiler chicks (Cobb-500) were divided into 3 groups (80 birds in each group). The first and second groups were vaccinated subcutaneously (s/c) on day-1 with Winterfield 2512-G61 and Winterfield2512 ICX vaccines, respectively, the third group left as non-vaccinated control group and all groups were challenged on day-35 with vvIBDV local field isolate (GenBank accession no.KX646373), The protection assessment based on mortality rate, clinical signs, postmortem gross lesions, bursa to body weight ratio (BBR), seroconversion and mean severity index (MSI) of histopathological lesion scores was evaluated. The results revealed that both vaccines provide complete protection against mortality and clinical signs after challenge with vvIBDV. In addition, the partial protection against bursal atrophy, the (BBR) were (0.76, 0.95 and 1.27) versus (0.49, 0.56 and 0.25) in Winterfield 2512-G61, Winterfield-2512 vaccinated and non-vaccinated groups before challenge and 7-days post-challenge, respectively. The results of this study indicate that the vaccination with Immune-complex vaccines can provide complete protection against mortality and clinical signs; they also provide partial protection against bursal atrophy and histopathological lesions and give adequate immune response against challenge with the Egyptian vvIBDV.
Application of a Novel Collocation Approach for Simulating a Class of Nonlinear Third-Order Lane–Emden Model

The present study aims to design a mathematical system based on the Lane–Emden third-order pantograph differential model by using the general forms of the pantograph as well as the Lane–Emden models. The designed model is divided into two types along with the various singularity details at each point. The shape factors and the pantograph points are discussed for each type of the newly designed nonlinear third-order pantograph differential model. The Bernoulli collocation scheme is implemented to find the numerical results of the novel model. To show the reliability of the designed novel nonlinear model, four different variants have been solved. Moreover, the comparison of the obtained results with the exact solutions is presented to check the accuracy of the designed novel model.
Digitalization and academic research: knowing of and using digital services and software to develop scientific papers

PurposeThis paper explores how digitalization affects the academic research publication process by taking into account the perspective of management scholars. It provides an overview of the digital professional services dedicated to academic research, and investigates academics' awareness of, the impact on the publication process of, and scholars' expectations regarding digital services and software.Design/methodology/approachThis explorative study adopted a qualitative approach by performing direct observations of websites regarding digital professional research services and in-depth interviews with national and international management scholars.FindingsThe multiple digital professional services dedicated to academic research enable authors to develop a scientific paper independently or with the support of professionals. The scholars' awareness regarding the digital services and software was limited, because of both the plethora of options on the market and the frequent use of the same digital tools over time. In impact terms, these tools enable scholars to improve research quality and to increase productivity. However, the negative effects led scholars to express different expectations about how they can be improved and what difficulties should be overcome to favor the publication process.Practical implicationsThe results of this study provide suggestions both for scholars who engage in academic research and digital services and software providers.Originality/valueTo the best of the authors' knowledge, this is the first study to examine the ongoing development of digitalization in support of the research publication process from the perspective of academics.
Decolonizing the Literature Review: A Relational Approach

As two (ab)Original women, we consider how a relational approach to the literature review can reflect our broader Indigenous and decolonizing research methodologies. In our research training, we have been exposed to dominant literature review models that advocate for researchers to “identify the gaps” and “occupy a territory,” a process (and vernacular) that feels at odds with Indigenous, relational, and decolonizing principles. We intend to apply the teachings we have learned from Indigenous scholars to the literature review process by proposing a reframing of the literature review, to one that is relational.
Serum Lipid Profile in Newborns with Intrauterine Growth Retardation and Its Comparison with Appropriate for Gestation Age Newborns

Background: Newborns with intrauterine growth retardation (IUGR) are known to permanently change their physiology and metabolism to adapt to limited supply of nutrients in utero. These programmed changes can later be the cause for the origin of diseases like coronary artery disease, diabetes mellitus and hypertension. If the premature development of cardiovascular risk factors can be anticipated during childhood, future events can be prevented effectively by taking appropriate measures. Objective of the Study: To study serum lipid profile of newborns with IUGR and Appropriate for Gestation Age(AGA) newborns and compare them. Methodology: This cross sectional study was conducted from February 2018 to September 2018 in the department of Neonatology, BSMMU, Dhaka, Bangladesh. Newborn who met the inclusion criteria, information regarding antenatal, natal and postnatal history were recorded in a data collection form after taking consent from the parents/guardians. Weight, length, OFC were taken along with other clinical examination. Serum samples of infant with intrauterine growth retardation and matched group of Appropriate for Gestation Age newborns were collected within 24 hours of postnatal age before starting feed and sent to Biochemistry laboratory of BSMMU and analyzed for lipid profile which included serum cholesterol, Triglyceride, Low Density Lipoprotein(LDL) and High Density Lipoprotein (HDL). All data were recorded in a preformed questionnaire and data was analyzed by statistical package for social sciences (SPSS) version 20. Quantitative data were expressed as mean\(\pm\) SD and categorical data were presented as proportion. All quantitative variables were compared by unpairedt-test; categorical variables were compared by Chi-square test or Fisher’s exact test. P < 0.05 was considered as significant. Pearson correlation was done to see the correlation between gestation age and lipid profile in both IUGR and AGA newborns. Results: Total population included 43 IUGR newborns and 43 AGA newborns who were matched by gestational age and sex. No significant difference was seen among both the groups based on demography except for birth weight which was lower in IUGR newborns than AGA newborns (1398.02\(\pm\) 307.14 vs 1777.91\(\pm\) 551.2 , p=<0.001). It was observed that serum triglyceride level in IUGR group was significantly higher than those in AGA group (90.23 \(\pm\) 48.16 vs. 70.13 \(\pm\) 27.76, p=0.020). Serum HDL-c level was found to be significantly lower in IUGR group as compared to AGA group (20.62\(\pm\) 8.88 vs. 26.95 \(\pm\) 7.91, p=0.001). There was a significant negative correlation between gestation age and serum LDL-c level in IUGR infants(r = -0.334). Conclusion: As compared to AGA newborns, IUGR infants had significantly higher levels of triglyceride and lower levels of HDL-c. Significant negative correlation was observed between gestation age LDL-c in IUGR newborns.
Moving liquid droplets with inertia: Experiment, simulation, and theory

This thesis is a work on a contact line instability at a finite Reynolds number, 0 < Re < O(100). This problem corresponds to an immersion droplet applied in a liquid- immersion lithography machine. We perform extensive works to understand this instability problem by means of experimental, numerical, and theoretical ways. First, in order to measure the 3D internal flow pattern, we perform 3D-3C velocimetry techniques, i.e. tomographic particle image velocimetry and 3D particle tracking velocimetry. Furthermore, we observe droplet shape changes by shadowgraphy. Second, based on these experimental results, we develop a modified three-dimensional lubrication model including inertial effects. In this model, the pressure is described as a combination of dynamic pressure effects and capillary pressure effects. By this extended model, we obtain an analytical solution describing the relationship between opening angles and receding angles. Additionally, we show a self-similar flow pattern near the dewetting contact lines. Last, a simplified numerical model is introduced for a liquid immersion droplet. For the numerical computation, we adopt a flat cylinder and apply a zero flux boundary condition at the gas-liquid interface. The numerical results are compared with measurement results and give a good agreement.
Prediction of electric vehicle charging duration time using ensemble machine learning algorithm and Shapley additive explanations

Electric vehicles (EVs) are the most important components of smart transportation systems. Limited driving range, prolonged charging times, and inadequate charging infrastructure are the key barriers to EV adoption. To address the problem of prolonged charging time, the simple approach of developing a new charging station to enhance the charging capacity may not work due to the limitation of physical space and strain on power grids. Prediction of precise EV charging time can assist the drivers in effective planning of their trips to alleviate range anxiety during trips. Therefore, this study employed four different ensemble machine learning (EML) algorithms: random forest, extreme gradient boosting (XGBoost), categorical boosting, and light gradient boosting machine, for predicting EVs' charging time. The prediction experiments were based on 2 years of real‐world charging event data from 500 EVs in Japan's private and commercial vehicles. The study emphasized predicting charging time for different charging modes, that is, normal and fast charging operations. The results indicate that EML models performed well under various scenarios, with the XGBoost model having the highest accuracy. Moreover, we also employ the newly developed Shapley additive explanation (SHAP) approach to tackle the non‐interpretability issues of the ML algorithm by interpreting the XGBoost model outputs. The obtained SHAP value plots demonstrated the nonlinear relationship between explanatory variables and EV charging time.
Susceptibilidad de Plutella xylostella a Heterorhabditis sp. SL0708 (Rhabditida: Heterorhabditidae)

Plutella xylostella (Lepidoptera: Plutellidae) conocida como polilla dorso de diamante (DDM) es una de las plagas más importantes en cultivos de crucíferas en Colombia. La estrategia de control más utilizada ha sido el uso de insecticidas de síntesis química como piretroides, carbamatos, organofosforados y reguladores de crecimiento. Como una alternativa de control, se evalúa la susceptibilidad del tercer instar de DDM al nemátodo entomopatógeno Heterorhabditis sp. SL0708 en condiciones de laboratorio. Se probaron cinco dosis de juveniles infectivos (JI) (0, 100, 300, 600, 1200 JI/ml/5 larvas) y se evaluó cada 24 horas la sintomatología, mortalidad y recuperación de JI. Las larvas afectadas por Heterorhabditis sp. SL0708 presentaron cambios de coloración de verde a marrón claro, se mostraron poco móviles y con cuerpo flácido. Algunas larvas alcanzaron a mudar a pupa y se observó el desarrollo de adultos de primera generación. El porcentaje promedio de mortalidad fue de 95,6%, con un tiempo de mortalidad entre las 48 y 72 horas. La dosis que mostró diferencias significativas fue 100 JI. De las larvas infectadas por tratamiento se recuperó en promedio diariamente 2.743 JI en cinco días. Las larvas de P. xylostella fueron susceptibles a los JI de Heterorhabditis sp. SL0708, indicando que se debe continuar evaluando su capacidad patogénica en invernadero y campo.
Effects of noise intensity on concentration levels of chainsaw operators and harvesting workers in industrial forest plantation, North Sumatera, Indonesia

Background Noise has the potential to affect the comfort and health of workers. The objective of this research was to determines the effects of noise on the concentration levels of both chainsaw operators and harvesting workers in industrial forest plantation, North Sumatra, Indonesia. Methods This experimental study included 20 respondents which consisted of 10 chainsaw operators/helpers and 10 harvesting workers. All respondents were exposed to the sound of a chainsaw in three different conditions (idle, half gas and racing conditions) with and without personal protective equipment (PPEs: earmuffs, ear plugs and without PPE). The sound intensity produced by the chainsaw and the noise received by the respondents were measured using a sound level meter. Respondents’ perception toward noise was recorded using a Likert scale. Respondents’ concentration level was assessed by giving 25 math-questions to be answered within 10 minutes. Wilcoxon sign rank test was used to analysed paired data. Results The average sound intensity received by respondents’ left and right ears were lower than the average sound intensity produced by the chainsaw. The use of earmuffs leads to better perception towards noise when compared with the use of earplugs and the absence of any PPE. Based on Wilcoxon test, the noise did not have significant impact on the concentration level of chainsaw operators, whilst the contrary result is true for harvesting workers. Conclusions The research indicated that although the noise produced by the chainsaw was considered noisy for both chainsaw operators and harvesting workers, it did not have a significant effect on the concentration level of chainsaw operators and only affected the harvesting workers. Therefore, given that the harvesting workers were still affected by the noise, noise control measures are still needed to ensure occupational safety and health for the workers.
POSSIBILITY OF DETECTING RELICT MASSIVE NEUTRINOS

The coherent intensification of the interaction of relict massive neutrinos with grains of matter with a size on the order of the neutrino wavelength suggests that it might be possible to detect a galactic neutrino sea by virtue of the mechanical pressure which it exerts in the direction opposite that in which the solar system is moving in the galaxy.
Finite-Resolution Digital Beamforming for Multi-User Millimeter-Wave Networks

Recent studies have shown that low-resolution analog-to-digital-converters and digital-to-analog-converters (ADCs and DACs) can make fully-digital beamforming more power efficient than its analog or hybrid beamforming counterpart over wide-band millimeter-wave (mmWave) channels. Inspired by this, we propose a computationally efficient fully-digital beamformer relying on low-resolution ADCs/DACs for multi-user mmWave communication networks. Both a generalized (unstructured) beamformer (GB) and a structured zero-forcing beamformer (ZFB) are proposed. For maintaining fairness among all users in the network, specifically tailored objective functions are considered under sum-power constraints, namely that of maximizing the geometric mean (GM) of users’ rate and their max-min rate. These computationally challenging beamforming design problems are tackled by developing computationally efficient steep ascent algorithms, which have the radical benefit of relying on a closed-form solution at each iteration. Moreover, to facilitate the employment of low-cost amplifiers at each antenna, the GB design problem subject to the equal-gain transmission constraint is considered, which assigns equal transmit power to each transmit antenna. The proposed algorithms promise a user-rate distribution having a reduced deviation among the user-rates, i.e., improved rate-fairness. Our extensive simulation results show an approximately upto 45% reduction for the GM-rate of a 2-bit ADC (4-bin quantization) compared to the $\infty$-resolution ADC.
NICUface: Robust Neonatal Face Detection in Complex NICU Scenes

The development of non-contact patient monitoring applications for the neonatal intensive care unit (NICU) is an active research area, particularly in facial video analysis. Recent studies have used facial video data to estimate vital signs, assess pain from facial expression, differentiate sleep-wake status, detect jaundice, and in face recognition. These applications depend on an accurate definition of the patient’s face as a region of interest (ROI). Most studies have required manual ROI definition, while others have leveraged automated face detectors developed for adult patients, without systematic validation for the neonatal population. To overcome these issues, this paper first evaluates the state-of-the-art in face detection in the NICU setting. Finding that such methods often fail in complex NICU environments, we demonstrate how fine-tuning can increase neonatal face detector robustness, resulting in our NICUface models. A large and diverse neonatal dataset was gathered from actual patients admitted to the NICU across three studies and gold standard face annotations were completed. In comparison to state-of-the-art face detectors, our NICUface models address NICU-specific challenges such as ongoing clinical intervention, phototherapy lighting, occlusions from hospital equipment, etc. These analyses culminate in the creation of robust NICUface detectors with improvements on our most challenging neonatal dataset of +36.14, +35.86, and +32.19 in AP30, AP50, and mAP respectively, relative to state-of-the-art CE-CLM, MTCNN, img2pose, RetinaFace, and YOLO5Face models. Face orientation estimation is also addressed, leading to an accuracy of 99.45%. Fine-tuned NICUface models, gold-standard face annotation data, and the face orientation estimation method are also released here.
Cumbres Mayores (Huelva, Spain): A new striking Megalith complex and its incise Lineal Megalithic and Tartessian Scripts

A big megalithic complex has been described at Cumbres Mayores (Huelva, Spain): it is composed of menhirs, a cromlech and some other not yet fully studied structures. Lineal Megalithic Scripts are present both on the rocks and the menhirs which also contain figure engravings. Iberian signs included within Iberian-Tartessian semi-syllabary are also found mixed with Megalithic scripts; Leisner archaeologists also noticed “Iberian Megalithic scripts” in 1951 at San Bartolomé Dolmen (Huelva). They are the same signs that also appear at a Sahara Desert cave (Ti-m Missaou, Algeria) and rocks throughout all seven Canary Islands. Lineal Megalithic Scripts have also been found in other Andalusian megaliths (dolmens) and throughout Andalusia in many big or small stones both in megalithic or non-megalithic contexts. These Iberian-Tartessian semi-syllabary signs present in a megalithic context would drive Iberian-Tartessian writing dating back to 3000 to 5000 years BP with a big geographic extension, comprising South Sahara Desert, Canary Islands and South Iberia. A political unit and a common language are not known to have existed but people from former green Sahara Area emigrated because rapid desertification after 6000 years BC and also people exchange across Gibraltar Strait exists since Prehistoric times. Finally, these Iberian-Tartessian megalithic signs are found in the core of classic Tartessian Cumbres Mayores area: this may put Tartessian civilization writing formation dating back to 5,000 - 3,000 years BC as already stated by Strabo.

BackgroundCovid-19 has unquantifiable negative impacts on the world’s socio-economic parameters. The rapid discovery of vaccines to fight this pandemic is a monumental scientific breakthrough.Study objectiveThe study assessed willingness of adult Nigerians to accept Covid-19 vaccine and elucidated on factors influencing such decisions.MethodologyCross-sectional design was employed among 400 respondents recruited using multi-stage random sampling technique in Ilorin, Kwara-State, Nigeria. Pretested interviewer-administered, semi-structured questionnaire was used for data collection. Both descriptive and inferential statistics were carried out.ResultsMean age ±SD of respondents was 40.85±13.75 and 215 (53.7%) of them were males. Those who possessed good knowledge of Covid-19 were 321 (80.3%), but few respondents had misconceptions regarding its causation. Attitude to Covid-19 vaccination was positive in 360 (90%) of the respondents, 278 (69.5%) were willing to accept the vaccine. Respondents’ Covid-19 knowledge and attitude to its vaccination were the main determinants of willingness to receive the vaccine.ConclusionThe Nigerian government urgently needs to leverage on the positive attitude of the people to fully implement its covid-19 vaccination policies which can ensure effective coverage and equitable access to the revolutionary Covid-19 vaccines. Awareness campaign on practice of other preventive measures should be sustained to produce a synergistic control effort.Rwanda J Med Health Sci 2022;5(2):127-140
Prevalence and Antibiotic Resistance Profiles of Carbapenem-Resistant Klebsiella Pneumoniae Isolated from Tertiary Care Hospital, Egypt

Background: Carbapenem-resistant Klebsiella pneumoniae (CR-Kp) dissemination is a major healthcare problem due to its limited treatment options. Objective: This study aimed to determine the prevalence and antimicrobial resistance profile of hospital infections caused by CR-Kp in Al-Ahrar Teaching Hospital. The study was conducted through the period from January 1, 2021 to December 31, 2021. Patients and Methods: 650 clinical samples were collected from different ICU departments. Klebsiella pneumoniae isolates were identified by conventional methods. Susceptibility to carbapenems and other antibiotics was determined by disk diffusion method. Results: Out of 650 clinical specimens, 142 K. pneumoniae were isolated with an isolation rate of 21.8%. K. pneumoniae showed that the majority (60.6%) of isolates were extensively-drug resistant (XDR), while 30.3% were multidrug resistant (MDR) and only 9.2% were susceptible. By disk diffusion method, the incidence of CR-Kp was 25.4% (36/142). Antibiotic susceptibility test showed that 100% of CR-Kp isolates were resistant to Amoxicillin/Clavulanic acid, Ampicillin/Sulbactam, Pipracillin/Tazobactam, cefepime, ceftriaxone, cefotaxime, cefoxitin, ceftazidime and nitrofurantoin. High rate of resistance was also evident to aztreonam, norfloxacin (88.9%, for each) and amikacin (61.1%). Levofloxacin owned the lowest resistance rate (30.6%), followed by ciprofloxacin (44.4%) and gentamycin (47.2%). Antibiotic resistance pattern of isolated CR-Kp showed that the majority of the isolates (97.2%) were XDR, while only 2.8% were MDR. Conclusion: About quarter of K. pneumoniae isolates were carbapenem-resistant with predominance of XDR isolates which represents a warning sign for which application of antibiotic stewardship is mandatory as well as strict infection control policies for prevention of development of pan-drug resistant bacteria.
