Authors: Kholoptsev Aleksandr V. , Podporin Sergey A.
Published: December 2022

The dynamics of the development of the Lena polynya formed on the shipping routes of the Northern Sea Route in the Laptev Sea and its influence on the conditions of navigation in the Arctic are studied. During the period of winter-spring navigation in the Laptev Sea, the Great Siberian polynya, which is located near the fast ice border and creates good opportunities for winter navigation on the Northern Sea Route, is formed. This problem is important to ensure year-round navigation in the Eastern Sector of the Northern Sea Route. The hypothesis that the terms of a polynya occurrence can significantly affect the average rate of its growth is tested in the study. When checking, the results of the GLORYS12v1 global reanalysis and standard methods of mathematical statistics are used. On the example of the polynya section located on the estuary seashore of the largest navigable channel of the Lena River Delta - Bykovskaya, the validity of the hypothesis is confirmed. Steady trends in the change in the polynya formation terms towards earlier dates in the modern period are revealed. A high probability of improving the conditions of navigation in this region in 2020-2040 is noted. At the same time, with further warming of the Siberian climate, the opposite process, namely, the freezing of a polynya that formed too early, which will lead to a cooling of the climate in the region and a deterioration in navigation conditions, is possible. Comparing the results obtained with other studies that are devoted to the construction of general routes for ships in various ice conditions, it is possible to identify trends that the actual routes during independent navigation pass along the forming polynyas, regardless of the physical principle of their formation, then the choice of general routes for ships in the areas of polynya distribution will be promote more intensive and safe shipping. What requires accurate forecasts of its size and position. The relevance of the research results for forecasting year-round navigation, both for independent navigation of ships with a high ice class, and in the development of plans for using icebreaking escort of ships, is noted.
OPTIMIZATION OF THE BARGE-TOWING COMBINATIONS CONFIGURATION DEPENDING ON THE OVERALL AND NAVIGATIONAL CHARACTERISTICS OF INLAND WATERWAYS
Authors: Zhidkova Anastasiya M.
Published: December 2022

The organization of transportation by inland water transport involves taking into account the overall characteristics and navigational features of waterways, the choice of a vessel to work on the route, ensuring the safety of navigation and the economic efficiency of the voyage. One of the main advantages of barge-towing combinations is the possibility of their formation according to the specified dimensions of the waterway. The purpose of this work is to overcome the linear approach currently used in the formation of the ship’s composition, and to develop mathematical foundations for describing the barge-towing combination control system, a particular task is to optimize the barge-towing combination structure for local restrictions of waterway sections. To solve this problem, the possibility of reorganizing the ship’s composition directly on the route, depending on the conditions for the passage of a particular section of inland waterways is supposed to study in the work; it in the future will improve the transportation efficiency and ensure the transportation of more cargo per voyage. For the mathematical description of inland waterways, their natural characteristics are used in the work, sections coincided in restrictive features are identified, that is, each section of inland waterways, depending on its type, has a certain set of restrictions related to overall characteristics that must be taken into account when organizing navigation. The simulation of the movement of a ship’s combination along sections of waterways of various types, including a curved section, performed by graphic-analytical methods, shows the limitations arising when entering a turn and passing through artificial narrowings of the fairway, and also reflects the ability to pass the entire route due to a change in configuration when maintaining the total carrying capacity of the ship’s combination. As a result, mathematical relations and a system of inequalities that determine the choice of a section of inland waterways for the operation of ship’s combinations in a certain (specified) configuration and planning their reformation according to the given characteristics of the waterway are obtained.
DEFINING PARAMETERS OF EQUILIBRIUM STRANDING OF A SHIP USING SIMULATION MODELLING
Authors: Egorov Denis A. , Gankevich Ivan G. , Degtyarev Aleksandr B.
Published: December 2022

Equilibrium stranding of a ship is a necessary preliminary step for application of other decision support system algorithms, such as identification of a flooded compartment, predicting an emergency vessel capsize probability, and others. The equilibrium stranding using a real ship as an example based on the heel angle sensors readings for rolling and pitching, and the water column pressure sensors readings for the vertical roll, is calculated. In the linear case, the mean value of an individual value coincides with the equilibrium position on the corresponding coordinate axis. However, a ship rolling in a sea is, as a rule, non-linear process, and hence the mathematical average correction is required. The use of the Nechaev’s method for determining the equilibrium position of a floating vessel in a heavy sea is illustrated in the paper. An algorithm based on simulation modeling in the Virtual Testbed software package is proposed. It has been proved that complication of wave model used for coefficients obtaining in Y. I. Nechaev’s algorithm changes obtained equilibrium parameter value insignificantly, but in this case time spent for generation of one simulation is increased significantly enough. When using linear waves or Stokes waves, the generation of two minutes of simulation is faster than two minutes of real time; when using Gerstner waves, the simulation time approaching three minutes of real time, which already exceeds the simulation time. In this case, when using the Stokes waves model, it is possible to achieve the results closer to the Gerstner model than when using the linear waves model without consuming additional time. This fact allows us to conclude about the optimal use of the algorithm.
PROPELLER SHAFTING DYNAMICS UNDER IMPULSE ACTION
Authors: Tsarenko Sergey N. , Ulitin Gennadiy M. , Trudnev Sergei Yu.
Published: December 2022

Propeller shafts and countershafts are bent quite often on sea and river vessels. The cause of the curvature is a strong load on this node of the ship’s power plant. In addition to bending, the shafting experiences longitudinal and transverse loads with a dynamic and static component. A large number of scientific papers have been devoted to the study of the dynamics of the propeller and shafting. However, the problem has not been completely solved, and the increase in damages during the shafting operation and its intensive wear only confirm the relevance of further research in this direction. The aim of the work is to determine the dynamic forces in the shafting, which occur during impulse action due to the propeller impact on the ice. A model of a two-stage elastic rod with inert disks at the ends is presented in the paper. It allows considering different situations of dynamic impact on the shafting and propeller. The following design features such as different stiffness of the shaft sections, different speed of elastic waves of deformation (different densities and modules of elasticity on the shaft sections), reduced inertial load from the moving parts of the drive, can be taken into account in the model. It is concluded that the frequency of the main form of oscillations mainly depends on the inertial loads concentrated at the ends and the shaft rigidity. The proposed simplified model of the inertialess shaft makes it possible to determine the angles of rotation of the shaft sections with sufficient accuracy. For different sections of the stepped shaft, the dynamic torque coefficient can differ significantly.

Published: December 2022

The commission of the corporate environmental crime is on the rise in Malaysia. This may be due to the existing legal system which stipulates minimal punishments and results in crime repetition. This study adopted a qualitative method through doctrinal legal research given the crucial need to assess and benefit from the prevailing implementation of deferred prosecution agreement (DPA) in another jurisdiction. This study aims to explore the suitability of DPA as an alternative tool to deter corporate environmental crime in Malaysia. Findings from the study demonstrated that DPA could effectively prevent corporate environmental crime in Malaysia.

First record of a fossil coral (Anthozoa) from Pleistocene deposits at Terra Ceia, North Carolina
Authors: Heads Sam , Taylor Steven
Published: December 2022

A fossil coral of the genus Solenastrea Milne Edwards & Haime (Anthozoa: Scleractinia: Faviidae) is reported from Pleistocene deposits exposed near the town of Terra Ceia in Beaufort County, North Carolina. The specimen is similar in gross and corallite morphology to Solenastrea hyades (Dana) which is common in Neogene and Quaternary sediments of North Carolina, but has been altered by vadose diagenesis, making confident assignment to species challenging. The specimen is the first coral recovered from the Terra Ceia locality which has, up to now, yielded only mollusks.

Published: December 2022

In this study, the oxidative stability of the cottonseed oil biodiesel (CB) and soybean oil biodiesel (SB) was investigated by two methodologies, Rancimat and Differential Scanning Calorimetry (DSC), using samples fresh and aged (mid-term storage condition (100 days)). The biodiesel samples were synthesized by transesterification and characterized by specific mass, kinematic viscosity, acidity value, ester content, viscosity index, and peroxide value. The activation energy (Ea), Arrhenius pre-exponential factor (Z), reaction order (n), and reaction rate at constant temperature (k(T)) were calculated by Borchardt and Daniels method. The results showed that oxidation affected the physicochemical properties of the biodiesel samples, especially, acidity (mg KOH/g), peroxide value (meq/1000 g), and induction period, with a decrease of around 55% for CB and 29% for SB. For kinetic parameters, the k(T) of both aged samples presented the highest values, with an increase of around 314% for SB. It was also observed that the rate constants increased with decreasing values of the induction period, in agreement with the current literature. According to the evaluation, the Borchardt and Daniels method can be recommended for a quick assessment of the biodiesel oxidation kinetic parameters.

Published: December 2022

Background

Traditionally, dengue prevention and control rely on vector control programs and reporting of symptomatic cases to a central health agency. However, case reporting is often delayed, and the true burden of dengue disease is often underestimated. Moreover, some countries do not have routine control measures for vector control. Therefore, researchers are constantly assessing novel data sources to improve traditional surveillance systems. These studies are mostly carried out in big territories and rarely in smaller endemic regions, such as Martinique and the Lesser Antilles.

Objective

The aim of this study was to determine whether heterogeneous real-world data sources could help reduce reporting delays and improve dengue monitoring in Martinique island, a small endemic region.

Methods

Heterogenous data sources (hospitalization data, entomological data, and Google Trends) and dengue surveillance reports for the last 14 years (January 2007 to February 2021) were analyzed to identify associations with dengue outbreaks and their time lags.

Results

The dengue hospitalization rate was the variable most strongly correlated with the increase in dengue positivity rate by real-time reverse transcription polymerase chain reaction (Pearson correlation coefficient=0.70) with a time lag of −3 weeks. Weekly entomological interventions were also correlated with the increase in dengue positivity rate by real-time reverse transcription polymerase chain reaction (Pearson correlation coefficient=0.59) with a time lag of −2 weeks. The most correlated query from Google Trends was the “Dengue” topic restricted to the Martinique region (Pearson correlation coefficient=0.637) with a time lag of −3 weeks.

Conclusions

Real-word data are valuable data sources for dengue surveillance in smaller territories. Many of these sources precede the increase in dengue cases by several weeks, and therefore can help to improve the ability of traditional surveillance systems to provide an early response in dengue outbreaks. All these sources should be better integrated to improve the early response to dengue outbreaks and vector-borne diseases in smaller endemic territories.

Authors: Yeh Ping Teresa , Kennedy Caitlin Elizabeth , Minamitani Ayako , Baggaley Rachel , Shah Purvi , Verster Annette , Luhmann Niklas , de Mello Maeve Brito , Macdonald Virginia
Published: December 2022

Background

Despite the growth of web-based interventions for HIV, viral hepatitis (VH), and sexually transmitted infections (STIs) for key populations, the evidence for the effectiveness of these interventions has not been reported.

Objective

This study aimed to inform the World Health Organization guidelines for HIV, VH, and STI prevention, diagnosis, and treatment services for key populations by systematically reviewing the effectiveness, values and preferences, and costs of web-based outreach, web-based case management, and targeted web-based health information for key populations (men who have sex with men, sex workers, people who inject drugs, trans and gender-diverse people, and people in prisons and other closed settings).

Methods

We searched CINAHL, PsycINFO, PubMed, and Embase in May 2021 for peer-reviewed studies; screened abstracts; and extracted data in duplicate. The effectiveness review included randomized controlled trials (RCTs) and observational studies. We assessed the risk of bias using the Cochrane Collaboration tool for RCTs and the Evidence Project and Risk of Bias in Non-randomized Studies of Interventions tools for non-RCTs. Values and preferences and cost data were summarized descriptively.

Results

Of 2711 records identified, we included 13 (0.48%) articles in the effectiveness review (3/13, 23% for web-based outreach; 7/13, 54% for web-based case management; and 3/13, 23% for targeted web-based health information), 15 (0.55%) articles in the values and preferences review, and 1 (0.04%) article in the costs review. Nearly all studies were conducted among men who have sex with men in the United States. These articles provided evidence that web-based approaches are as effective as face-to-face services in terms of reaching new people, use of HIV, VH, and STI prevention services, and linkage to and retention in HIV care. A meta-analysis of 2 RCTs among men who have sex with men in China found increased HIV testing after web-based outreach (relative risk 1.39, 95% CI 1.21-1.60). Among men who have sex with men in the United States, such interventions were considered feasible and acceptable. One cost study among Canadian men who have sex with men found that syphilis testing campaign advertisements had the lowest cost-per-click ratio on hookup platforms compared with more traditional social media platforms.

Conclusions

Web-based services for HIV, VH, and STIs may be a feasible and acceptable approach to expanding services to key populations with similar outcomes as standard of care, but more research is needed in low-resource settings, among key populations other than men who have sex with men, and for infections other than HIV (ie, VH and STIs).

Authors: Liang Bingyu
Published: December 2022

BACKGROUND

The outbreak of monkeypox around the world in May 2022 is another health threat for who have sex with men (MSM), which accounts for almost all patients.

OBJECTIVE

This study aimed to describe the knowledge of Monkeypox, worries about monkeypox, their awareness of prevention strategies, willingness towards monkeypox vaccination and their correlates factors among MSM in China.

METHODS

Methods: In this regard, we conducted a cross-sectional survey of MSM in southern China from August to September 2022. Multivariate logistic regression was used to explore the correlates willingness of monkeypox vaccination and its correlates.

RESULTS

Results: Participants (N=1093) ranged in age from 18 to 70 years and mean age was 27.9 years. Over two-thirds 343(68.6%) had anal sex for one to five times in the past three months .999(91.4%) of participants were willing to receive a monkeypox vaccine and 639(89.4%) obtained information about monkeypox through the Internet. In multivariable analysis, considered the vaccine to be safe (aOR=6, 95%CI: 1.402–25.678), agreed that it was necessary for the government to promote smallpox/monkeypox vaccination in China (aOR=6.195, 95%CI: 1.038–36.993), agreed that smallpox/monkeypox vaccine should be given priority to MSM (aOR=8.88, 95% CI:1.742–45.274) and whose friends or sexual partners had received the monkeypox vaccination (aOR=14.305, 95%CI: 2.621–78.070) were more likely to be willing to receive monkeypox vaccine. Participants (729,66.7%) were aware that they were at a high risk of monkeypox infection and agree that vaccine should be given as a priority to MSM (661,60.5%). Those who were married (aOR=0.155, 95% CI: 0.039–0.614), had engaged in anal sex 4–6 times per week in the past three months (aOR=0.279, 95% CI: 0.089–0.875) and who received Jynneos (aOR=0.111, 95% CI: 0.013–0.922) were less likely to take the monkeypox vaccination.

CONCLUSIONS

Conclusions: There was a relatively high willingness of monkeypox vaccination among MSM in China. The hesitancy of monkeypox vaccination can be effectively addressed by eliminating concerns about the safety of the vaccine and adverse reactions to vaccination, and by increasing the acceptance of monkeypox vaccination of their peers among MSM.

Published: December 2022

Abstract: Social media platforms like Facebook, Whatsapp, Twitter, and Telegram are important sources of information diffusion in the modern period, and people believe it with- out questioning its authenticity or source. Social media has fascinated people worldwide in spreading fake news due to its easy availability, cost-effectiveness, and ease of information sharing. The website – pmssgovt online claims that the scheme is applicable to all Indian students studying from class 9 to graduation degree. The website was fake and was charging Rs 450 as the registration fee for students to participate in the said scheme. Fake news can be generated to mislead the community for personal or commercial gains. It can also be used for other personal benefits such as defaming eminent personalities, amendment of government policies, etc. Thus, to mitigate the awful consequences of fake news, several research types have beenconducted for its detection with high accuracy to prevent its fatal outcome. This article proposes a framework for detecting fake news based on feature extraction and feature selection algorithmsand a set of voting classifiers. The proposed system distinguishes fake news from real news. First, we preprocessed the data taking unnecessary characters and numbers and reducing the words in the dictionary (lemmatization). Second, we extracted some important features by using two types of feature extraction, the term frequency-inverse document frequency technique and bag ofwords. Third, the extracted characteristics were reduced with the help of the different machine learning algorithm and the analysisof the variance algorithm. At last, challenges and open issues along with future research directions are discussed to facilitate the research in this domain further

Quantum speed limits on operator flows and correlation functions
Authors: Carabba Nicoletta , Hörnedal Niklas , Campo Adolfo del
Published: December 2022

Quantum speed limits (QSLs) identify fundamental time scales of physical processes by providing lower bounds on the rate of change of a quantum state or the expectation value of an observable. We introduce a generalization of QSL for unitary operator flows, which are ubiquitous in physics and relevant for applications in both the quantum and classical domains. We derive two types of QSLs and assess the existence of a crossover between them, that we illustrate with a qubit and a random matrix Hamiltonian, as canonical examples. We further apply our results to the time evolution of autocorrelation functions, obtaining computable constraints on the linear dynamical response of quantum systems out of equilibrium and the quantum Fisher information governing the precision in quantum parameter estimation.

Conhecer a ciência é saber que o conhecimento científico demanda um caminhar construído no decorrer de anos e de forma não vertical. Compreender esse processo é ser alfabetizado cientificamente. Sendo assim, este trabalho buscou relatar uma experiência com ações pedagógicas que abordam a importância do estudo da história da ciência (HC) e da alfabetização científica (AC) na formação de professores. Para desenvolver as ações pedagógicas, optou-se pela abordagem qualitativa com a participação de vinte e quatro alunos matriculados na disciplina de HC do Curso de Licenciatura em Química do IF Sertão-PE, que responderam a um formulário inicial na plataforma Google. Para a análise dos dados, utilizou-se a análise de conteúdo com três categorias pré-estabelecidas. Os resultados evidenciam que os alunos que fizeram parte da pesquisa compreenderam a importância da HC para sua formação; porém, não conheciam o termo AC. Portanto, há uma necessidade de um ensino que aborde a AC de forma mais explícita durante a formação dos alunos no curso de Licenciatura em Química.

Num cenário em que os jogos digitais têm sido alvo de críticas da mídia de massa, desassociados do cenário educativo, este estudo surge para fortalecer a vertente da aprendizagem baseada em jogos digitais no ensino superior. Para este propósito, o seu objetivo geral foi investigar as percepções de um professor e de seus estudantes em torno do processo de aprendizagem de um conteúdo de Ecologia durante o desenvolvimento de um jogo digital RPG numa universidade brasileira. O estudo teve abordagem qualitativa com delineamento em pesquisa-ação pedagógica. Utilizamos a entrevista semiestruturada e questionário para coletar os dados que foram analisados com a técnica Análise do Conteúdo. Como resultados, professor e estudantes concordam que a mediação, colaboração, criação da história, personagens e diálogo com outras mídias influenciaram no processo de aprendizagem do conteúdo científico trabalhado em sala de aula.

Published: December 2022

Este trabalho relaciona o tema violência curricular e seu vínculo com a pedagogia do oprimido com os conceitos da análise bakhtiniana, como fundamentos para refletir sobre o uso da linguagem em sala de aula. Para tanto, consideram-se as salas de aula como ambientes de aprendizagem heterogêneos que se transformam a cada encontro ao longo de um ano letivo ou no decorrer de um período da vida escolar dos sujeitos. Diante disso, foram analisadas as relações dialógicas em sala de aula, a partir das dimensões extraverbal (social) e verbal (verbo visual) de enunciados. Essa investigação foi objetivada pela busca em compreender relações entre enunciados de estudantes e uma linguagem não violenta em aulas de ciências. Assim, as reflexões oriundas dessa análise indicam a existência de vozes que produzem situações de polifonia ou monofonia, presentes nos enunciados emitidos no ambiente escolar, mais particularmente no ensino de ciências. A presente pesquisa se mostrou como uma contribuição produtiva para reflexões sobre o uso da linguagem em aulas de ciências.
Altitude diving on a closed-circuit oxygen rebreather: A case report
Authors:   Memorial Hospital, University of Colorado at Colorado Springs, Colorado U.S., Conard Jonathan
Published: December 2022

Closed-circuit rebreather diving is becoming more common. Rebreathers are complicated, adding to the stress of diving. Also adding to this complexity in the presented case is diving at a high-altitude cold-water reservoir in Colorado. One diver experienced an oxygen-induced seizure at depth. The other diver had a rapid ascent with loss of consciousness. As will be seen in this case, two experienced divers were able to recover from a possible devastating dive. Fortunately, they both returned to their pre-dive baseline health. Dive planning is important, but as in this case, dive execution is paramount. This is a clinical case for an uncommon event that presented to an emergency department.
The implications of auditing outsourcing on the sustainability of audit services
Authors: Al-Taee Salowan Hafadh Hamed , Al-Jauhar Kareema Ali Kadhim
Published: December 2022

The overarching goal of this study is to clarify what is meant by the term “accounting outsourcing” and to identify the various accounting and auditing tasks that might be delegated to external auditors. Accounting auditors do more than just explain the benefits and drawbacks of outsourcing accounting and auditing services and other services. However, they also detail the specific outsourcing services that auditors provide in Iraq, and make suggestions for improving the efficiency and longevity of such services. The researchers used a questionnaire to collect data from businesses and auditors’ offices in Baghdad, and the descriptive analytical method to the hypotheses. The local environment study based on the contribution of Adams (2018) reveals that the bulk of the auditor’s work consists of economic feasibility studies and services closely related to auditings, such as internal control and fraud audits. Accounting and internal audits are two of the lowest-priority services. Subcontracting is the least prevalent form of support while enlisting the help of internal authorities to complete the work or providing only partial support is the most common
Examining the relationship between sustainability reporting processes and organizational learning and change

Published: December 2022

Although there have been a number of publications discussing sustainability reporting (SR) in private and public sectors within the last decades, the number has been quite low when compared to works on non-governmental organizations (NGOs). This research explores this and finds that SR is a key driver for organisational learning and change in NGOs. A combination of descriptive statistics, grounded theory (GT) and inferential statistics was used to analyse the data. The findings show that SR and organisational learning and change share a reciprocal relationship that begins as the driver for learning and extends as change. This reciprocal relationship is repetitive and improves reporting process through enhanced sustainability performance in a mimetic approach. The research shows that SR fosters opportunities for cost and benefit evaluation, the institutionalization of sustainability, transfer of skill and innovation, attitudinal change towards sustainability, stakeholder engagement and ownership, as well as increasing the donor base. The findings further reinforce the contention that SR is influenced by organisational culture, donor behaviour and management decisions. The study also communicates the various lessons learnt from NGOs’ sustainability efforts that other NGOs, private and public sectors can benefit from.

Authors: AL-SULTAN Moatasem A. M. , ALTINOLUK Serra
Published: December 2022

In this study the solar cell parameters depending on the electrical and physical properties of a semiconductor material were simulated and optimized with high accuracy and with a short simulation time. To obtain highly efficient solar cells in theory, later on for practical applications, Personal Computer One Dimensional (PC1D) software simulation program was used. The parameters were the thickness of emitter and absorber layers, type of absorber layer, doping profile, antireflective coating (ARC) materials and surface texturing. The results observed with the optimized parameters were compared and verified with the experimental results in the literature.
modelling ductile fracture in third stress invariant sensitive materials: application to al2024-T351
Authors: Bonora Nicola , Testa Gabriel , Ricci Sara , Iannitti Gianluca , Ruggiero Andrew
Published: December 2022

Triaxiality alone is not sufficient to account for the role of stress
state on ductility in materials that exhibit shear effects on fracture
strain. For these materials, it has been proposed that ductility also
depends on the third invariant of the stress deviator. Recently, Bonora
and Testa [N. Bonora, G. Testa, Plasticity damage self-consistent
model incorporating stress triaxiality and shear-controlled fracture
mechanisms – model formulation, Eng. Frac. Mech. 271, 108634 (2022).]
derived a plasticity damage self-consistent (PDSC) model considering
damage contributions due to intervoid necking, shearing, and sheeting
for an arbitrary stress state. In this work, the PDSC model has been
applied to Al2024-T351 considering the experimental results reported in
the literature obtained on several different sample geometries and
material batches. The ability of the model to predict the transition
from cup-cone to slant fracture for different stress states is shown. In
addition, the possibility to predict ductile fracture in the negative
stress triaxiality range has been also demonstrated showing that it can
occur for stress triaxiality even much less than -0.5 as long as there
is a dominant shear deformation state.

The World Health Organization (WHO) has launched campaigns to boost
immunization rates to 70 percent globally by the middle of 2022.
However, despite the global success of about 64% COVID-19 vaccination
coverage, there is a big gap in Nigeria. To date, only 13.8% of the
population has received the recommended dose. This demonstrates a
significant disparity between the vaccinated and the unvaccinated.
Amidst the wide gap in vaccination, COVID-19 vaccine wastage still
occurs in Nigeria. At the end of 2021, it was estimated that over a
million doses of the COVID-19 vaccine had been wasted. It is anticipated
that there will be more COVID-19 vaccine wastage in Nigeria, because of
the combined factors that threaten vaccination uptake including vaccine
hesitancy, lack of appropriate storage facilities, poor electricity
supply, insecurity challenges, and inadequate health promotion. This
results in concomitant financial and opportunity losses. In this paper,
we discuss COVID-19 vaccine wastage in Nigeria including causes, and
solutions that can be applied to mitigate this wastage.
