Elucidating the Complex Interrelationship on Early Interactions betweenLeishmaniaand Macrophages
Authors: Sampaio Tavares Veras Patrícia , Castro-Gomes Thiago , Perrone Bezerra de Menezes Juliana
Published: July 2022

The host’s ability to eradicate or control infection caused by intracellular pathogens depends on early interactions between these microorganisms and host cells. These events are related to the organism’s nature and stage of development and host immune status. Pathogens are recognized by host cells, which respond to infection by either mounting an efficient response or becoming a replication niche. Early interactions between the protozoan Leishmania parasite and host cell receptors activate different signaling pathways that can result in microbe elimination or, alternatively, infection establishment and the migration of Leishmania infected cells to other host tissues. This chapter focuses on Leishmania-macrophage interaction via phagocytosis, which involves a range of parasite ligands characteristic of Leishmania species and parasite stage of development and diverse host cell receptors. We also discuss alternative Leishmania entry by cell invasion and review how Leishmania spp. survive and replicate within the phagocytic compartment they induce.
Supply Chain: A Modeling-Based Approach for Cyber-Physical Systems
Authors: Bányai Ágota
Published: July 2022

Within the frame of this chapter, the author focuses on the distribution processes of green supply chain solutions and describes a potential mathematical model, taking environmental aspects into consideration. The first part of the chapter includes a systematic literature review. Based on the identified research gap, a new mathematical model is described, which makes it possible to describe last-mile logistics processes from an environmental point of view. The functional model of the distribution system includes the potential of Industry 4.0 technologies, which makes it possible to gather real-time information from the distribution process and use real-time status information for a sophisticated design and operation. The mathematical model of this approach defines an NP-hard optimization problem; therefore, heuristic optimization algorithm is supposed to solve the design and operation tasks of the green distribution problem. As the computational results show, cyber-physical systems increase the performance of green supply chain solutions and have a great impact on operational cost. As the numerical example shows, the integrated approach resulted in a 5.3% cost reduction in transportation operations.

Authors: Hossari Hosna , Elfahli Kaoutar
Published: July 2022

Today, green human resource management (GHRM) has become a key business strategy where HRM plays an active role in the ongoing green movement. Thus, the topic of GHRM is of growing interest among management scholars. However, despite the theoretically important role of GHRM, relatively small number of research has been discovered so far about how GHRM, in companies striving to achieve environmental sustainability, could help them gain a green competitive advantage (GCA). Thus, based on the resource-based view (RBV) arguments, the main objective of this paper is to develop a conceptual model of the relationship between GHRM and green competitive advantage through green knowledge, green values, and green commitment. This model is expected to provide a strategic map that could be utilized by the practitioners and managers so that GHRM implementation can be more effective in contributing to green competitive advantage. Overall, the present article extends knowledge on the resource-based view by contributing to the literature on GHRM and its interactions with the main assets that lead to green competitive advantage.
Caries Management Aided by Fluorescence-Based Devices
Authors: Galuscan Atena , Jumanca Daniela , Doris Fratila Aurora
Published: July 2022

Fluorescence-based intraoral cameras are increasingly gaining more interest in the modern dental practice, as an aid for the early detection of carious lesions. Such devices can have different operating systems, such as infrared lasers, quantitative light fluorescence (QLF), or LED lights, but they all rely on the fluorescent properties of tooth structures. Healthy enamel and enamel affected by demineralization have different light-scattering properties, a fact that allows for distinction under excitation with light of a known wavelength. The central problem in the treatment of dental decay is that operational care is still considered the predominant management plan for caries control in the general practice. Devices that use fluorescence have the potential to improve the detection and management of carious lesions significantly. Currently, there are several intraoral devices that employ fluorescence on the market, but more validation studies would be required to uphold the interest of the newly developed devices and to justify their reliability in clinical practice. Dental professionals cannot yet solely rely on one single-fluorescence device for incipient caries diagnosis, but they already present themselves as useful adjunctive tools to traditional examination methods.

Authors: Bauk Sanja
Published: July 2022

The purpose of the paper is to present a conceptual framework of blockchain (BC) deployment in shipping and port management, which encompasses distributed relational database (DB) and crypto-currency payment mechanism as main constructs. The core of the model is TradeLens platform. The document workflow management, financial processes and device connectivity are key scenarios in the proposed framework. The stakeholders play the role of traditional intermediaries in goods, accompanied data, and documents flows, including overall supervision of the processes between end-nodes, that is shippers (consignees) and customers (consumers). The paper identifies some strengthens and frailty of blockchain-based maritime supply chain system and proposes further investigation in this domain, towards better understanding prospective development of blockchain across maritime cluster.
Influence of flooding boat deck compartment on the ship’s safety
Authors: Mironiuk Waldemar
Published: July 2022

At any time whether during combat or non-combat, naval ships are susceptible to damage. During combat, navy ships are susceptible to suffer damage to a particular degree on its armament, hull or even its technical equipment. The damages are of specific nature and occur at specific places on the ship. For example, during combat, a navy ship can suffer damage from torpedoes and mine explosions, impact resulting from artillery shells, missiles or airborne bombs or even due to effects from weapons of mass destruction. This damage results in flooding of the affected areas. During the ship's operation at sea a significant threat to its safety is fire. Although fire rarely causes the ship to sink, the damage that it leaves is usually very serious, though the extent of the damage depends on the level of crew training in the area of emergency response. The main extinguishing agent used on ships is usually sea water, which in large quantities poses a threat to the safety of the ship. It affects changes in the stability and position of the ship. Determination of these changes is the basis for the sub-capacity calculations related to the operation of a damaged ship. Therefore, the main focus of the work was to determine the impact of flooding of high-located compartments on the safety of a ship. The results of the calculations presented in the paper include information about the amount of water in the range causing deterioration of the stability of the ship.

Authors: Strabić Marko , Brčić David , Frančić Vlado , Komadina Pavao
Published: July 2022

In the shipping industry, Sea Traffic Management (STM) system aims to represent a new paradigm in maritime safety. The idea of the STM implementation is to share information between all stakeholders, making shipping more efficient, safe, and environmentally friendly. With the growing market and related increase in marine transport and traffic, the risk of marine accidents is increasing as well. The STM provides numerous features for personnel on-board and shore to support decisions for safe navigation and operation based on real-time data.
One of the services is the ship-to-ship route exchange, providing prediction of potentially dangerous situations and planning the vessel’s movement in advance. Analyses of marine accidents show that ship collisions are one of the most frequent types of marine accidents, the reason of which among all others, questions human error related to the knowledge of collision avoidance. This paper elaborates on the possibility of COLREGs/STM integration based on the use of STM ship-to-ship route exchange system. The decision model for COLREGs/STM integration procedure is presented in a way which enables suggestion on appropriate COLREG rule application in advance. Further system development is proposed as well, such as machine learning algorithms in COLREGs/STM integration, with the function of reducing the risks of marine accidents and increasing safety at sea.

Published: July 2022

The paper explores the importance of sustainability from the perspective of prospective employers of future and existing Maritime Education and Training (MET) graduates. More specifically, it investigates employers’ views on the incorporation of sustainability into MET provision. For this purpose, a questionnaire survey that addresses the concept of sustainability – among other emerging trends - from the angle of maritime education and training was distributed to European shipowning companies in the context of related EU funded research (SkillSea). A total of 23 responses were received but, albeit the relatively small sample, the findings suggest clearly that there is a significant gap between the skills presently acquired through MET. They also reveal the need for METs to develop a strategy aiming at a more comprehensive inclusion of the mega-trend of sustainability as a subject into the curricula of the various types of MET institutions. This paper contributes to the literature by addressing the mismatch between current and future needs and related issues arising for maritime education and training.
Static maritime enviroment representation of electronic navigational charts in global path planning
Authors: Sakan Davor , Žuškin Srđan , Rudan Igor , Brčić David
Published: July 2022

In past years, numerous global path planning methods have been researched and applied in maritime surface navigation. Regardless of intended usage for either decision-support in manned, or autonomous vessel navigation, path planning should generate a safe and efficient route. However, prior to route generation, static maritime environment representation must be created first. Whether it is transformed in to discrete or continuous form, common approach is to use Electronic Navigational Charts (ENCs) as a basis for maritime environment representation. Nevertheless its origins, ENCs still adhere to inherited data generalisations and simplifications to be comprehensible for human navigators. This leads to limitations when considering path planning and spatial resolution at different chart scales. Furthermore, when generating the representation and path, uncertainty must be considered since the quality and accuracy of chart data varies. Although these topics have been addressed separately in their respective domains, their relations have not been researched in detail. The aim of the proposed paper is the review of electronic navigational charts, environment representation and common global path planning approaches’ relations. Forthcoming standards and technologies, such as usage of high-density charts, are presented and discussed as well.

Authors: Benedict Knud , Schaub Michele , Baldauf Michael , Gluch Michael , Kirchhoff Matthias , Krueger Caspar
Published: July 2022

Some port approaches require challenging manoeuvring strategies for arrival and departure, specifically under heavy wind and current conditions. In recent papers a discussion of the “Stern-First-Method” SFM was started suggesting that it would be beneficial to go astern into the harbour instead of the conventional bow first method. In this paper the SAMMON software for “Simulation Augmented Manoeuvring Design, Monitoring & Conning” will be used to analyse this SFM for challenging scenarios to provide insights into the potential benefits of this methods. This software is based on the innovative “Rapid Advanced Prediction & Interface Technology” (RAPIT) to simulate the ships motion with complex dynamic math models and to display the ships’ future track immediately based on Fast Time Simulation in an Electronic Navigational Chart for any rudder, thruster or engine manoeuvre planned by the navigator. The SAMMON system has been developed and matured over years, and promising experiences were made at the Maritime Simulation Centre Warnemuende MSCW and other centres. Currently, specifically the use of the SAMMON Manoeuvring Planning tool will be an element of the transfer of knowledge within the current ERASMUS+ project EURO-ZA between the partners from Europe South Africa. The benefits for increasing the effectiveness of lecturing and simulator training have been proven in previous publications and will be made visible in this paper by using simulator ships both twin screw and azimuth propulsion for discussion of the SFM manoeuvring strategies.
Incorporating virtual reality into maritime safety training to enhance competency-based learning outcomes
Authors: Helal Hesham
Published: July 2022

The potential of using immersive technologies like Virtual Reality (VR) in education is endorsed by several research studies indicating an expected increase in its use within the foreseeable future. Owing to its capacity to provide a highly interactive and immersive experience, the adoption and integration of VR into maritime safety training can create new opportunities for competency-based learning and teaching methods. In a safety-critical domain such as the maritime industry, safety training is crucial for ensuring trainees’ competency in emergency response and survival skills. This is accomplished through a range of training programs that were specifically tailored to address emergency events. However, during training exercises, fear and anxiety can have a substantial influence on trainees performance, especially if the activity is stressful as the "Helicopter Under Water Escape Training" (HUET). To address this problem, it is essential to psychologically prepare the trainees before executing the exercise. Driven by this aim, this applied research claims that incorporating VR technology into the classroom prior to practical exercises might contribute to achieving the best feasible results of the preparation by improving skill acquisition while mitigating fear and disorientation.
The methodology followed in the study consists of two stages; the first comprises a 3D-Camera recording the training exercises from the trainee’s seats view, and examples of commonly committed faults. The trainees watch these recordings in VR headsets before practicing the exercises. The second stage entails conducting, collecting and analyzing trainees’ questionnaire, as well as observations raised by training instructors to distinguish viable elevations in trainees’ performance. Based on the outcomes of this study, it can be concluded that VR technology considerably enhances learning by enabling trainees to anticipate difficulties of the exercises, hence contributing to improved training performance.

Published: July 2022

Peixoto et al. (2020) apresentaram uma metodologia que utiliza dados oriundos da mobilidade de pessoas para classificar municípios de um estado em três zonas de risco (baixo, médio e alto) em relação a uma doença contagiosa transmissível pelo ar. Os autores aplicaram o modelo para avaliar a exposição dos municípios dos estados de São Paulo e Rio de Janeiro à COVID-19, antes que o vírus estivesse amplamente disseminado. Nosso objetivo neste artigo é avaliar como essa metodologia de classificação de risco se aplica no Rio Grande do Sul e como ela se relacionou com a evolução da COVID-19 no estado. A partir dela, obtivemos uma classificação dos municípios do estado em três grupos de risco. Nessa divisão, com raras exceções, municípios mais próximos de Porto Alegre ficaram classificados como alto risco. A região da serra, do litoral e de alguns municípios no oeste do estado ficaram em um risco médio. Os demais municípios foram classificados com risco baixo. Em comparação com os dados oficiais sobre a disseminação da doença no estado verificamos que o risco atribuído foi coerente com a evolução da COVID-19. De um ponto de vista metodológico, encontramos evidências, via clusterização espectral, que dividir os municípios em três grupos é a melhor escolha para os nossos dados.

Published: July 2022

The use of hazardous chemicals has become a common practice to control diseases that affect agricultural production. In this scenario, society is challenged to increase food availability while reducing pesticide use, which causes damage to health and the environment. In this sense, essential oils appear as a promising alternative to reduce the use of pesticides, since they are plant-derived compounds. This study aimed to identify the main chemical components and evaluate the in vitro antimicrobial potential of essential oils of the Brazilian species Elionurus latiflorus and the exotic species Cymbopogon flexuosus against the phytopathogenic bacteria Xanthomonas axonopodis pv. phaseoli, Ralstonia solanacearum, Pectobacterium carotovorum pv. carotovorum and Pseudomonas syringae pv. tomato. The main component identified of the essential oils was citral at the concentrations 65.38% for E. latiflorus and 71.6% for C. citratus. The analysis of the antibacterial activity of the essential oils showed effect against all bacteria analyzed when compared to the antibiotic gentamicin. The antibiotic produced inhibition zone diameters from 11.30 to 20.67 mm, while the essential oils produced the inhibition zones from 51.22 to 90 mm and pure citral around 86 mm. MIC values for essential oils were found between 25 and 200 µL/mL and MBC between 100 and 400 µL/mL. The study showed that the oils have inhibitory effect on the microorganisms tested.

Titanium dioxide nanoparticles promote histopathological and genotoxic effects in Danio rerio after acute and chronic exposures
Authors: Machado Kayser Juliana , Carolina Schuster Andriéli , Zimmermann Prado Rodrigues Gabriela , Dal Pont Morisso Fernando , Gehlen Günther
Published: July 2022

Titanium dioxide nanoparticles (TiO2-NPs) are among the most used nanomaterials worldwide, but studies evaluating its genotoxicity and histopathological effects are scarce, dealing with short exposure times and low concentrations for human use. The aim was to evaluate TiO2-NPs genotoxicity and histological alterations in the intestine and liver of zebrafish after exposure to human consumption compatible concentrations. Fishes were acutely (96 hours) and chronically (30 days) exposed to 5.0, 20 and 40 mg L-1 of TiO2-NPs and later euthanized for organ and blood analysis through histological procedures and the micronucleus test, respectively. An increase in the thickness of intestinal villi was observed after acute and chronic exposure in the higher concentrations. The liver showed an increase in vacuolated hepatocytes after both exposures, besides an increase in hepatocytes with peripheral nucleus. Genotoxicity was only observed after chronic exposure, demonstrated by the increase in micronucleus and cell buddings. These findings indicate that TiO2-NPs cause histopathological damage even in acute exposures, as the intestine serves as a barrier for NPs and the liver is an organ that accumulates Ti. Genotoxicity was possibly mediated by reactive oxygen species through chronic inflammation, leading to tissue damage and carcinogenesis in longer exposures that represents human exposure time.

Authors: Cruz Letícia Giese de Andrade , Andrade Fernando Oliveira de , Araujo Anderson Nascimento de
Published: July 2022

The present work performs statistical evaluations of the HEC-HMS hydrological model for the six sub-basins that form the Tibagi River watershed, located in the central-eastern region of the state of Paraná, Brazil. The physical characterization of the study area is developed by techniques of geographic information systems. The effective rainfall is estimated using the SCS curve number method, the baseflow is determined by a recession curve method, and hydrographs are simulated using the SCS unity hydrograph method. The simulated hydrographs are compared with measured outflow data of the six sub-basins for a selected period of 2017. The performance of the models is assessed using a validation criterion based on RSR, NSE e PBIAS statistical indexes. After input parameters calibration, the comparisons of the hydrographs show excellent agreement with measure data according to the classification adopted in the work. The simulated peak flows range from 3.3 to 8.6% when compared to the observed peak flows, indicating that the model can assist in the prediction of maximum discharges.

Published: July 2022

This paper aims to investigate stationarity in the pluviometric historical series of the state of Ceará, Brazil. After selection, the gaps were filled using linear regression. The Mann-Kendall and Pettitt tests were conducted with the help of the package “trend”, in R programming language. After applying the tests, it was noted that most of the selected stations presented stationary behavior, except for Chorozinho, which presented a p-value of 0,018 for the Mann-Kendall test, i.e., rejecting the null hypothesis of stationarity at 5% significance and presenting a positive monotone trend. For the Pettitt test, the station presented a p-value of 0,022, thus rejecting the null hypothesis of lack of change point at 5% significance, the change point being in the year of 1982. It is concluded that it was possible to analyze the stationarity of historic pluviometric series and have a better understanding of the hydrological regime of the region.

Free for all? Knowledge as a barrier in technopolitical communities in Spain
Authors: Calvo Dafne , Campos-Domínguez Eva
Published: July 2022

Optimistic visions of its liberating potential have accompanied the Internet since its inception. However, technopolitical communities have defended free knowledge, but they risk adopting liberal notions when there is a group hierarchy depending on technological skills or the time people invest in the project (Coleman & Golub, 2008; Crabu et al., 2016). Using a combined methodology, we aim to understand the decision-making and training processes of technopolitical communities in Spain. Results show that these projects are collective, and their communities are aligned with the availability of public materials on the Internet for individual learning and mutual support values. However, they must consider developing better-established training and decision-making strategies to attract more people and more diverse profiles. Otherwise, there is a risk of generating an elite of experts who may enjoy free knowledge but cannot effectively collectivize it and disrupt the context of informational capitalism.

Published: July 2022

Entrepreneurial competencies are considered a vital piece for aspiring entrepreneurs to pursue entrepreneurial ventures. The research aimed to examine the personal entrepreneurial competencies scores of accountancy, business, and management (ABM) students in a private institution. A quantitative method engaging in descriptive research was employed in the study. The study utilized Slovin's formula, with 187 ABM students responding. The data were analyzed using mean and ranking. The findings revealed that goal-setting and information-seeking garnered high scores and were rated first and second, respectively, with an interpretation of ‘strong traits’ and their strengths among the identified entrepreneurial competencies. Persuasion and networking and risk-taking obtained moderate scores and were ranked 9th and 10th, respectively, and accordingly labeled as inferior characteristics. The researchers concluded that a plethora of inside and outside-of-school activities related to entrepreneurship could enhance the information-seeking skills of students. It was also determined that students' self-awareness should be strengthened since taking risks is a key component of being a successful entrepreneur. Furthermore, the study suggested that increasing entrepreneurial activities both within and outside the campus will be valuable to ABM students in developing entrepreneurial competencies, particularly for characteristics belonging to the moderate level.

Authors: Padma Kumari , Saka Deepthi , Fernandes Sharol , Nanaware Sagar , Patil Ishwar , Ransing Ramdas
Published: July 2022

Introduction: Coronavirus Disease-2019 (COVID-19) pandemic is associated with more psychological distress than its rampant spread, mortality, and morbidity. Cancer patients are at increased risk of mortality and morbidity than the general population. Due to this, there is a possibility that cancer patients may be suffering from a higher level of COVID-19 related anxiety, fear, and obsession. Aim: To explore COVID-19 related mental health issues (anxiety, fear, and obsession) and its correlates in patients with cancer. Materials and Methods: The present study was a crosssectional pilot study which was conducted in a tertiary care teaching hospital located in Ratnagiri, Maharashtra, India. Patients receiving treatment for cancer (n=55) consequently at tertiary care teaching hospital of India were recruited. The Corona Anxiety Scale (CAS), Obsession with COVID-19 Scale (OCS), Fear of COVID-19 Scale (FCV-19S), Patient Health Questionnaire-9 (PHQ-9), and Generalised Anxiety Disorder-7 Scale (GAD-7) were used to assess all eligible patients. Fisher’sexact test, spearman’s rank correlation, and logistic regression were used to analyse the data. Results: Among the 55 patients (mean age was 49.64±13.08 years) with cancer, 11 (20%) had Coronavirus related anxiety and 2 (3.6%) had obsession related COVID-19, 22 (40%) had depression and 18 (32.7%) has GAD. CAS score positively correlated with FCV-19S score [ρ=0.50 (p<0.001)], PHQ-9 score [ρ=0.90 (p<0.001)] and GAD-7 score [ρ=0.74 (p<0.001)]. Conclusion: COVID-19 related mental health issues (fear, anxiety), depression, and GAD were prevalent among patients with cancer. Further, COVID-19 specific issues may not be addressed in routine screening and evaluation in current practice. Therefore, there is an urgent need to develop systematic strategies to screen and develop specific mental health interventions for patients with cancer

Authors: Salian Akshatha , Gireesh GR
Published: July 2022

Introduction: High blood pressure, also known as Hypertension (HTN) is a long-term medical condition in which the blood pressure in the arteries remains consistently high. HTN rates in India are expected to rise. Abdominal breathing exercise activates the parasympathetic nervous system which decreases the heart rate and dilates blood vessels, reducing overall blood pressure. Aim: To find out the effectiveness of abdominal breathing exercise on biological parameter among hypertensive patients. Materials and Methods: This quasi-experimental time series design study was conducted at Yenepoya Medical College Hospital, Mangaluru, Karnataka, India, from February 2021 to March 2021. A total of 60 samples were selected, with 30 samples in each of the control and experimental groups. Abdominal breathing exercise was given for 5-10 minutes about 3-4 times a day for seven days after the pretest of biological parameter assessment. Data was collected for three alternative days. The tools used were demographic proforma and clinical assessment proforma. Unpaired t-test and chi-square test were used for statistical analysis. Results: About 53.3% of the participants in the control group were males as compared to 66.7% in experimental group. The mean value of pretest Systolic Blood Pressure (SBP) and the Diastolic Blood Pressure (DBP) had no significant difference (p>0.05). However, after the abdominal exercises, there was significant difference in the mean SBP (p=0.01), DBP (p=0.01), Pulse Rate (p=0.05), Respiratory Rate (RR) (p=0.01) in experimental group when compared to control group. Conclusion: The study concluded that abdominal breathing exercise reduced BP, HR and RR among hypertensive patients and it is an effective technique to reduce BP, PR and respiration.

Malignant melanoma presenting as multiple lytic bone lesions masquerading as carcinoma of unknown primary on clinical and histopathological examination. Malignant melanomas are aggressive tumours with frequent metastasis to lymph nodes and viscera. However, patients presenting with osseous metastasis of melanoma with no known primary source is relatively rare. The terminology “metastases of unknown origin” is used when the site of the primary neoplasm cannot be identified at the time of diagnosis despite a thorough history, physical examination, appropriate laboratory testing and imaging studies. Metastatic melanoma can have varied presentations. Herein, this is a case report of a 63-year-old female who presented with swelling in the occipital region of eight-month duration. Examination showed bony hard fixed swellings in the occipital and mastoid regions. Computerised Tomography scan (CT scan) showed lytic bone destruction in the occipital and mastoid part of right temporal bone, associated with soft tissue mass. With the differential diagnosis of metastatic carcinoma and myeloma, biopsy was taken which showed infiltrating neoplasm with plasmacytoid cells in cords and in vague nests surrounded by fibrosis. The neoplastic cells were Cytokeratin negative, Cluster of Differentiation (CD) 138 negative and showed patchy nuclear positivity for S100. On subsequent examination, the neoplastic cells showed diffuse strong positivity for HMB 45 (Human Melanoma Black) and patchy moderate positivity for Melan A confirming the diagnosis of malignant melanoma. Primary lesion could not be detected even after a detailed past medical and surgical history, physical examination and radiological investigations. The main causes of skull lytic lesions in adults are metastatic carcinoma and plasma cell myeloma. Possibility of metastatic melanoma should also be considered in cases of skull bone lesions as melanomas could exhibit varying cellular morphology mimicking carcinoma, sarcoma or haematolymphoid neoplasms.

Mango plays an important role in socio-economic transformation of rural masses in the state. Proper assessment of area and production estimate is a prerequisite for effective horticulture planning Optimum stratification brings gain in precision in estimation of a characteristic of the population with limited time, money and human power. The primary data of area and production of mango of 325 mango orchardists of Himachal Pradesh were collected through well designed survey. The area under mango, auxiliary variable, was then subject to stratification in order to stratify the mango production, study variable. Four stratification methods 1) Equalization of Strata Total 2) Equalization of cumulative  \(\sqrt{f(y) 3}\)  3) Equalization of cumulative  \(\sqrt[3]{f(y)}\)  and 4) Equalization of cumulative1/2[r(y)+f(y)]   were used for stratification of area under mango production into varying number of strata L = 3, 4, 5, 6. From each strata a SRSWOR sample was drawn of size ni which was allocated by using proportional and Neyman allocation. After that estimate of mean and variance were computed for varying number of strata and for varying number of sample sizes n = 60, 90 and 120 allocated by proportional and Neyman allocation under these four stratification rules. The gain in precisions was also computed and is presented. It was found that \(\sqrt[3]{f(y)}\) for L = 6 and n = 120 yield minimum variance and maximum gain in precision. This showed that optimum stratification will lead efficient estimates and can be used for estimation of production in the state.

Quinoa seed powder and stevia has several health benefits. stevia has been naturally incorporated with sugar making it beneficial for diabetic patients. Burfi was an Indian popular sweet with harmful content and qualities. So, burfi was prepared using quinoa seed powder and stevia to incorporate benefits of plant compounds quercetin and kaempferide with the help of physicochemical analysis, proximate analysis, phytochemical analysis, antioxidant analysis shelf-life analysis and colour estimation analysis. The moisture content of optimized burfi and control burfi was obtained to be 15-20% percent respectively. The protein content of optimized burfi and control burfi have value 18.97-20.286% percent respectively. The fat content of optimized burfi and control burfi were 18.630-21.972% percent respectively. The ash content of optimized burfi and control burfi 3.4-4% percent respectively. The Titrable acidity of optimized burfi and control burfi were 1.035-1.16% percent respectively. The carbohydrate of optimized burfi and control burfi were 31.66-25.708% percent respectively. The crude fiber of optimized burfi and control burfi were 0-1.25% percent respectively. The calcium of optimized burfi and control burfi were 571-520 mg respectively. The pH of optimized burfi and control burfi were 7.99-8.03 pH respectively etc. Antioxidant activity was analysed using the in standard spectrophotometer method. Optimized quinoa burfi was investigated for their in-scavenging activities using 1,1-diphenyl-1-2 picrylhydrazyl (DPPH).  Then  check the Shelflife at 10 days.

Background: Poisoning is defined as exposure of an individual to a potentiality harmful substance either by inhalation, skin contact, ingestion, or injection.

Aim of the Work: This study aimed to develop and validate a novel scoring system using vital signs, arterial blood gases (ABG) and consciousness level as a tool of triage for evaluation and outcome prediction of acutely poisoned patients.

Methods: The current prospective cohort study was conducted on patients with acute poisoning who were admitted at Tanta University Poisoning Treating Center (TUPTC) throughout a period of start of April 2020 to the end of June 2021. For each patient, age, sex, and toxicological characteristics were obtained. Clinical examination and routine laboratory investigations were also done.

Results: Significant differences were observed between survivors and non-survivors in the derivation group (444 patients) regarding systolic blood pressure, diastolic blood pressure, respiratory rate, temperature, blood pH, PaCO2, serum HCO3, and O2 saturation. Using univariate and multivariate regression analysis SBP, serum HCO3, and O2 saturation were valid to construct the prediction score at cut off ≤100 mmHg, ≤16.6 mEq/L, and ≤93% respectively. Variables were given points and the score has range from 0 (the best score) to 3 (the worst score). The discrimination power in the derivation group at cut-off point >1 was excellent (AUC: 0.925) with 91.3% sensitivity and 94.9% specificity. Additionally, the discrimination power in the validation group (140 patients) at cut-off point >1 was excellent (AUC: 0.965) with 87.5% sensitivity and 93.8% specificity.

Conclusion: This proposed score could be considered a simple and excellent tool for triage to identify acutely poisoned patients who are at risk of mortality. In addition, it is validated and so it could be used in other populations.
