Working on a designated COVID-19 unit: Exploring nurse perceptions and experiences
Authors: Doas Michelle Dellaria
Published: July 2021

Objective: The COVID-19 global pandemic has had a distressing effect on clinical nursing units, creating unique challenges for the nursing profession. These unprecedented challenges included constant fear of the unknown, major disruptions to daily routines, the need to adapt to the realities of new safety protocols, the need for continuous donning and doffing of PPE, and an alarming increase in patient acuity and death. Rapid increases in COVID-19 hospital admissions prompted hospital administrators to designate specific medical-surgical nursing units as covid units. As a result, nurses faced the real possibility of bringing the virus home to their loved ones and possibly contracting a deadly disease. To understand the impact of COVID-19, a study was conducted to assess nurses’ perceptions, morale, emotions, current knowledge and susceptibility to developing compassion fatigue.Methods: Content analysis was used to identify registered nurses’ perceptions and experiences while providing nursing care during the COVID-19 pandemic. Additionally, data was collected to assess participants’ emotional and physical well-being, knowledge and susceptibility to developing compassion fatigue.Results: Nurses’ qualitative responses were categorized into seven themes. Additionally, compassion fatigue knowledge and susceptibility responses were analyzed.Conclusions: Associated feedback, including narrations, provided a framework to assist nurses with accessing resources to manage stressors, combat compassion fatigue symptoms, promote resiliency, and increase communication skills.

Published: July 2021

The increasing use of chemical insecticides has adversely effected the environment and increased insect resistance. Biopesticides have been noticed the potential to be an excellent alternative to chemicals to reduce the negative impacts to human health and the environment. Tomato (Lycopersicon esculentum) is the second most important vegetable crop worldwide due to its nutritional importance. The effect of NOVOSECT SC21® (0.5 L/200 L), ATO BED BUGS® (1 L/200 L) and NEO-BOOST® (1 kg/200 L) against Tuta absoluta, Liriomyza trifolii and Alternaria solani was studied. A complete randomized block design (CRBD) was used with three replications, three treatments and one control in Hrajel area in Lebanon in the summer of 2020. We evaluated the level of infestation and larval mortality level of Tuta absoluta, Liriomyza trifolii and Alternaria solani infection 24, 48 and 72 hr after the application. Results showed that NOVOSECT SC21® (Mix of metabolites of the Bacillus F.D. 777) was the most efficient in decreasing the infestation and inducing larval mortality level of T. absoluta and L. trifolii and the fungal infection induced by A. solani with significant difference with time, followed respectively by ATO BED BUGS® and finally NEO-BOOST®.

The form of distribution found for the dendro/morphometric variables determines the structure, stability, productivity of forest stands, being a tool to propose silvicultural interventions, management, conservation of species, and dynamics of this environment. Thus, this study evaluates, using probability density functions (pdf), the form of distribution of these variables for araucaria in five sites in southern Brazil, aiming to establish the dynamics and identify the existence of a standard—or the lack thereof—to propose the need for silvicultural interventions to conserve the species and the future forest structure. The Normal, Log-Normal, Weibull and Gamma probability density functions were tested. Results show no significant changes in the shape and dimension in the forest structure dynamics, but a period of stability in the pattern of dendro/morphometric values, resulting from the stagnation of the values of the variables, non-intervention in the forest, relationship with the site, density, competition, and position of the tree in the forest stratum, which compromises the future structure of this forest typology. The study proves that the distribution probability of the variables can be used in management for species conservation and future structure development, as this influences the growth dynamics and processes, resource availability, and the stability, diversity, vitality, and productivity of the species.
Prevalence and Incidence of Cassava (Manihot esculenta) Brown Leaf Spot Disease Caused by Cercospora heningsii in Macuata Province, Vanua Levu, Fiji
Authors: Prasad Rahul Ravneel , Dean Mohseen Riaz Ud , Alungo Bradley , Chand Vinal Vishal
Published: July 2021

Cassava (Manihot esculenta Crantz) is a crop of many values in the tropical and subtropical regions of the globe. In Fiji, cassava is cultivated on vast acres of land but, the yield obtained is relatively lower because of many constraints, including the prevalence of diseases caused by the different pathogens. Among various pathogens responsible for a lower yield, the cassava brown leaf spot disease caused by Cercospora heningsii is responsible for causing enormous annual losses of cassava in tropical and subtropical regions. Because there is very little information regarding the association of the brown leaf spot disease and cassava in the country, the present study using survey as research instrument endeavors to determine the disease incidence and prevalence of brown leaf spot disease in the cassava fields of three villages (Mani Road, Boca, and Anuve) in the Bulileka area of the Macauta province in Vanua Levu, Fiji. The study found that brown leaf spot disease prevailed (100%) in all three villages. The percentage of disease incidence ranged from 36.4% to 42.9%. The maximum incidence (42.9%) of cassava brown leaf spot disease was found in Anuve village, followed by Mani Road village (38.2%), with the lowest disease incidence recorded for Boca village (36.4%).
A NOTE ON RECURSIVE ESTIMATOR OF THE DENSITY FUNCTION WHICH IS NOT NECESSARY CONTINUOUS
Authors: EL-FAHHAM M. M.
Published: July 2021

Consider a sequence $X_1$, $X_2, \cdots , X_n$ of independent, identically distributed random variables with unkown density function $f$, which with its first derivative are not necessarily continuous, and let
\[f_n^*=(n^2h_n)^{-1/2}\sum_{j=1}^{n}h_j^{-1/2}K\left(\frac{x-X_j}{h_j}\right)\]

be the recursive kemel estimator of $f$. It will be shown, under certain additional regularity conditions on $K$ and $|h(n)|$, that, $MISE\ [f^*_n(x)] =o (n^{-4/5})$ if $f$ and $f'$ are continuous, whereas $MISE\ [f^*_{n_1}(x)] =o (n^{-3/4})$ if $f$ is continuous and $f'$ is not and $MISE\ [f^*_{n_2}(x)] =o (n^{-1/2})$ if $f$ and $f'$ ara not continuous.

The article deals with the metaphor and metaphor constructions in the novels by Vasyl Stefanyk. In linguistics, metaphor is one of the ways to understand and knowledge of the world, so in the language system metaphor is interpreted as a universal mechanism of semantic change, it has an anthropocentric nature and is based on semantic and conceptual knowledge of the world. In Vasyl Stefanyk's artistic world, metaphor is a mean of creating portrait characteristics and images, and often performs an evaluative function.

Authors: Piechocki Rafał
Published: July 2021

Today’s technological development and the expansion of audiovisual media do not allow us to neglect the potential of a properly selected music video in the teaching process. In addition to the acquisition of linguistic and media competences, the learner has the opportunity to acquire and/or broaden sociocultural knowledge i.e. knowledge about the society and the culture of a given community. For this reason, the present paper discusses the use of the music video at foreign language classes and attempts to answer the following questions: What had the combination of a moving picture and music looked like over the years before the music video was made? What is the significance of the music video in the context of the application of new technologies? What challenges does the work with the music video pose to a foreign language teacher? In addition, the paper presents a number of reasons why it is worth including the music video in the teaching process.

Zmagania z poczuciem winy – o dylematach przebaczenia samemu sobie w opiniach studentów pedagogiki i słuchaczy Uniwersytetu Trzeciego Wieku
Authors: Skrocka Dorota
Published: July 2021

The problem of self-forgiveness can arise when a person discovers his or her own weaknesses and limitations. As a result, the anxiety that he or she feels becomes either a consequence of the harms done to other people their suffering or regret because of their own faults and imperfections. Therapists often point out that the feeling of guilt is not only painful or fruitless, but it can also be seen as a chance for a change and recovery. However, this approach requires the difficulty of understanding, settling with oneself and taking responsibility for what has become the cause of internal accusation, so that unprocessed guilt would not lead to breakdowns, self-rejection, contempt. Therefore, in the conducted research students of pedagogy and students of Third Age Universities, were asked about their opinions on: What it is and how they assess forgiving oneself? It was considered that the obtained data and possible differences between adults, however, representing two different age groups, would allow the selection of categories of guidelines or restrictions explaining attitudes towards the issues discussed. In the declarations of future teachers and reflections of people who followed the hardships of life experiences, an assessment of the process was noted that allows freeing from the burden of one’s own negligence and making wrong decisions.

Every culture and every professional group are characterized by a system and hierarchy of values. Man is oriented towards a world of values: we can recognize, classify and fulfill them. This is also a teacher’s role. It is extremely difficult to educate young generations without presenting to them those values that serve an individual’s development and determine their perception of what is important in life. Values learned and experienced can be applied to real life; moreover, they make a teacher’s work more meaningful.
„Teraz […] już wiem, czego należy się wystrzegać i co czynić, by osiągnąć prawdę…”. Wokół Kartezjańskiej koncepcji cogito
Authors: Ostrowska Urszula
Published: July 2021

The desire to achieve unquestionable knowledge and experience in history with the history of events in all spheres of history from time immemorial. For every scientist, finding the truth is conditio sine qua non, a challenge and a duty. In the course of the history of human thought in its development tirelessly searched for the most effective ways of achieving a revealing one that meets scientific criteria. In the history of science so far, many concepts in this field arouse unique ones for various reasons. Reflection on the legacy of the French physicist and mathematician René Descartes (1596-1650), one of the most outstanding scholars of the 17th century and one of the most famous and effective philosophers in history, is an inspiring source of research, his works, the reading of which verbally motivates reflection and also to the endless endeavors of mankind in the pursuit of knowledge to the discovery of truth. By exposing the power of reason of reason as the axis, I made the thinking person, adopting the credo in the form of I think, therefore I am… as the first principle of philosophy. There are interesting interpretations of Descartes' sentences, which testify to a fairly strong tradition on a global scale. The assessment from the justification of the grounds to questioning Descartes' concept must be found that the undoubted merit of the philosopher is inspiring his contemporaries and successors with faith in the power of reason and motivating them to take actions that prove its power, including efforts to put them into practice.
Gravidez na adolescência e violência doméstica no contexto da atenção primária à saúde
Authors: Aguiar Camilla Moura , Gomes Kilma Wanderley Lopes
Published: July 2021

Introdução: A gravidez na adolescência tem ainda alta incidência no Brasil, mesmo após grande redução nas últimas décadas, e pode estar relacionada a situações de vulnerabilidade social e de violência doméstica. A Estratégia de Saúde da Família (ESF) é fundamental na atenção à saúde do adolescente, entretanto tem se mostrado pouco atuante no enfrentamento das violências nessa faixa etária. Objetivo: Este estudo objetivou descrever o perfil socioeconômico e identificar características materno-fetais e situações de vulnerabilidade social das jovens com histórico de gravidez na adolescência, analisando possíveis associações com a ocorrência de violência doméstica.Metodologia: Trata-se de estudo transversal, com entrevista de 100 adolescentes entre 13 e 19 anos com histórico de gravidez em 2018 de bairro pobre de Fortaleza - CE. Foi aplicado questionário com 57 questões e as variáveis analisadas foram as relacionadas ao perfil sociodemográfico, ao seguimento do pré-natal, ao nascimento da criança e à exposição à violência doméstica durante a gestação. Foram realizados teste qui-quadrado (χ2) e Odds Ratio (OR) na análise. Resultados: A idade média das entrevistadas foi 17,5 anos (dp=1,65). A renda familiar média foi 1,18 salário-mínimo (dp=0,83), 91% eram negras ou pardas, 57% estavam em união consensual e 18% tinham emprego. Com relação à escolaridade, 71% haviam interrompido os estudos, sendo que 46,5% delas o fez antes da primeira gravidez e 35,2% pararam de estudar depois de engravidar. No seguimento de pré-natal, 96,3% realizaram pelo menos uma consulta, 62,1% iniciaram no primeiro trimestre e 69,1% realizaram 6 ou mais consultas. Dentre as crianças, 7,6% e 6,4% nasceram prematuras e com baixo peso respectivamente. A porcentagem de violência doméstica foi 26% e o principal agressor foi o companheiro. Sofrer violência doméstica teve associação estatisticamente significativa com baixa escolaridade (OR 4,06; IC95% 1,27-12,97), menor idade materna (OR 4,2; IC95% 1,43-12,32) e “história de internação de recém-nascido” (OR 3,83; IC95% 1,34-10,95). Conclusão: As mães adolescentes estavam inseridas em contexto de vulnerabilidade social e parte considerável foi vítima de violência durante a gestação, situação associada à baixa escolaridade e menor idade da adolescente. As consequências negativas para saúde do recém-nascido foram mais frequentes em situações de violência. Notou-se que as adolescentes tiveram boa frequência no pré-natal e isso pode ter influenciado positivamente os desfechos obstétricos e neonatais. A gestação é, muitas vezes, o primeiro contato dessa jovem com o serviço de saúde e acesso à assistência pré-natal na ESF pode reduzir complicações materno-infantis e auxiliar na identificação da violência doméstica.
The political system of Bosnia and Herzegovina and the fault lines set down in the Dayton Agreement
Authors: Petrović Slobodan
Published: July 2021

This article seeks to review some of the problems with the political system of Bosnia and Herzegovina as expressed through the constitutional provisions of the Dayton Agreement. While the Agreement brought an end to the physical violence, its creators must have been aware that the type of state system it envisaged, being composed of two entities, only put off the solution to the crucial cause of the problem. The entire mechanism of the political organisation of BiH is based on the fault lines set down in this Agreement, while the continuing inter-ethnic struggle in BiH is focused on the questions which it poses for constitutional government. Furthermore the moderators of the process retained the right to monitor the Agreement’s implementation, institutionalising the involvement of the international community and introducing a continuing role for NATO in the Balkans. The article considers the political system of BiH as developed under the Dayton Agreement but turns first to setting the scene by exploring the territory of the country as a whole and some of the essential characteristics of its peoples.
The impact of EU conditionality policy on human rights and rule of law in the western Balkans: An attempt at a methodology
Authors: Qerimi Qerim
Published: July 2021

This article seeks to explore the underlying methodological dimension of measuring the impact or effects of the EU’s policy of conditionality in western Balkans states in the arena of human rights protection and respect for the rule of law. These are critical issues in which aid conditionality has global dimensions, while the EU itself remains a valid international actor. The article also focuses on the adequacy of the measurement instruments used to measure the impact of this policy, based on the existing trends as well as past experience with enlargement to central and eastern Europe. The author identifies the major research questions that need to be confronted and suggests an appropriate methodological approach to resolve these, including an important gender dimension. In the process, he identifies the deficiencies concerning the measurement of conditionality which have come to haunt the application of the policy. The central aim kept in mind throughout is to seek improvements in the application of the policy itself and with a view to the wider lessons regarding the role that conditionality has come to play.
Construction of the Surdulica Memorial Ossuary in reports of Serbian newspapers in 1922
Authors: Antić Dejan
Published: July 2021

With the retreat of the Serbian army towards Albania and Corfu, at the end of 1915 the territory of the Kingdom of Serbia was occupied by the forces of the Central Powers. In the division of the occupation plunder, the areas of southeastern Serbia and Vardar Macedonia belonged to the Kingdom of Bulgaria. During the three-year reign over the conquered areas, the Bulgarian occupation troops committed countless crimes. The small town of Surdulica became a symbol of the suffering of the occupied south of Serbia in the Great War, the place where mass crimes had been committed against the civilian population. After the liberation of Serbia in 1918, the citizens of this town launched an initiative to build a memorial ossuary in which the remains of the killed civilians would be buried. The subject of interest of our work is the reporting of the print media on the laying of the foundation-stone for the construction of the Surdulica Memorial Ossuary in 1922. At the same time, we analyzed the details of the newspaper articles about the suffering of the civilian population in Surdulica during the Great War (1915-1918) and the fate of the remains of numerous victims.

Published: July 2021

The article presents the attempt to follow the trail of the connection between the morphological and typological researches in architecture and urbanism. The principles of morphology and typology are noticed as unavoidable for comprehension of the entire context of the discipline of architecture and urbanism. The interaction between architectural typology and urban morphology are particularly emphasized as the most multilayered and most complex form of typological classification. The attention is directed towards stressing the unique morphological typological discourse of theoretical researches and practical implementation in architecture and urbanism, the basic concept of which is to transform the experience gained into a sort of code, which would be the pattern for the new step in further transformation of architectural and urban elements of the urban spaces in future.
Weaknesses regarding occupational health and safety in Macedonian companies
Authors: Mladenovska Daniela , Dubravac Ilina
Published: July 2021

The current situation regarding Occupational Health and Safety in Macedonian companies and institutions is not satisfying. Very often these issues are neglected by the management. There is also a lack of transparency in terms of accident reporting. Therefore, Macedonia is far behind the EU average in terms of registered injures at works. This paper deals with some of the most frequent barriers and irregularities in this field, by analyzing the results from the survey conducted among the employees in Macedonian companies and institutions. The participants are divided into 3 groups - public entities and state administration, large companies and small and medium enterprises. The survey outcome indicates that the awareness, transparency as well as investments in this area are still not sufficient. Moreover, there is a lack of skilled and trained professionals in this field, especially in state-owned entities.
Lo bello natural, lo bello romántico, el kitsch, la vanguardia y el carácter enigmático de la obra de arte en Th. W. Adorno
Authors: Búa Soneira Juan Ramón
Published: July 2021

El propósito de este trabajo reside en la aclaración y, a la vez, amplificación de algunos pasajes importantes de la Teoría estética y otros textos de Th. W. Adorno donde, de un modo fragmentario, se apela al curso histórico que va desde lo bello natural y lo bello romántico hasta la vanguardia y el kitsch. Para ello, se tomará la referencia de Adorno a Greenberg como punto de llegada de la discusión estética establecida entre Kant y Hegel. Así también, para finalizar, se alude al carácter enigmático de la obra de arte, a partir del cual, Adorno expone la dificultad de comprender la obra a partir del receptor y oyente en su necesidad de mediación entre forma y contenido, esto es, entre la autonomía estética y el fait social que componen la obra misma.
Sobre la memoria y la experiencia de conformación en el saber sobre sí mismo en Xavier Zubiri
Authors: Alberdi Sudupe Jesus
Published: July 2021

Memoria y experiencia están muy próximas entre sí en el ejercicio del entendimiento humano. La conformación es una de las modalidades de la experiencia, una modalidad decisiva para el saber de uno mismo.La experiencia es parte de la actividad racional humana, y consiste en la probación física de realidad de las construcciones lógicas y racionales que elaboramos a partir de los recuerdos decantados en la memoria, individual, social e histórica.Tratándose de uno mismo, y a diferencia de lo que podemos llegar a saber de otras cosas y de otras personas, el modo de hacer la probación física de lo que postulamos cada uno de sí mismo, adquiere unas características propias. Es lo que Zubiri llama experiencia de conformación de uno mismo. Su resultado es el saber de uno mismo.
¿En el regazo de la Iglesia? Las disputas políticas por la educación femenina en Francia y España en el siglo XIX
Authors: Mínguez Blasco Raúl
Published: July 2021

Mediante una perspectiva comparada, el objetivo de este artículo es ofrecer algunas claves explicativas de por qué la educación, particularmente la femenina, se convirtió en motivo de discusión y debate público a lo largo del siglo XIX y, más concretamente, entre los años 1865 y 1875 en Francia y España. La hipótesis que se defenderá es que la discusión pública en torno a la educación femenina se activó en momentos en los que los precarios consensos sobre cuestiones más generales como el papel de la religión o la función de las mujeres en la sociedad se tambalearon. Se abordarán dos casos concretos de estudio que nos permitirán calibrar el alcance de la politización de la educación femenina: el intento de establecer una escuela secundaria pública para niñas en los últimos años del II Imperio y la negativa a jurar la Constitución de 1869 por parte de algunas maestras con fuertes convicciones religiosas.
La masculinidad católica en la revolución: un aspecto de la politización de masas en el Reino de las Dos Sicilias (1820-1848)
Authors: Delpu Pierre-Marie
Published: July 2021

Las sucesivas revueltas y revoluciones que experimentó el Reino de las Dos Sicilias a lo largo de la primera mitad del siglo XIX se caracterizaron por la construcción de un nuevo arquetipo, el hombre católico, una figura movilizadora que supuestamente representaba al ciudadano regenerado y que se asociaba a un sistema de valores tomados de la religión, pero trasladados a la arena política de forma secularizada. Se benefició del apoyo dado por parte del bajo clero a los movimientos liberales y democráticos, por el lugar que ocupaban en la pedagogía revolucionaria. Las figuras promovidas en esa época, la del héroe militar y la del mártir político, constituyen modelos éticos ampliamente desarrollados en la literatura liberal, pero cuyos usos evolucionaron: el desarrollo de corrientes radicales a partir de los años 1830 y 1840 consagró el papel de las masculinidades cristianas luchadoras, capaces de resistir al gobierno de Fernando II, percibido como tiránico.

Seaway Load Prediction Algorithms for High Speed Hull Forms
Authors: Sikora Jerome P. , Klontz Nathan B.
Published: July 2021

This paper documents the generation of several seaway load prediction algorithms for catamarans, trimarans, and surface effect ships based on available model and full-scale test data. Froude scaling laws are used for geometrically different ships for each ship and load type using first principles and empirically derived studies. Simple seaway load prediction algorithms are then developed and expressed as functions of ship displacement and various key ship particulars. These global load algorithms are quickly computed, making them suitable for preliminary or concept design studies. In some cases, algorithms were developed from a minimum amount of data, and it is anticipated that as more data is gathered in the future, these algorithms will be further refined. As the ship design progresses, more accurate but time consuming computational analyses and model tests are appropriate.

Authors: Paik Jeom Kee , Hughes Owen F. , Hess Paul E. , Renaud Celine
Published: July 2021

The present paper is a summary of recent research and developments related to some core ultimate limit state (ULS) technologies for design and strength assessment of aluminum multi-hull ship structures, jointly undertaken by Pusan National University, Virginia Tech, U.S. Naval Surface Warfare Center and Alcan Marine. An extensive study on the subject has been undertaken by the authors theoretically, numerically and experimentally. Methods to analyze hull girder loads / load effects, stiffened panel ultimate strength and hull girder ultimate strength of aluminum multi-hull ship structures are developed in the present study. Application examples of the methodologies for the ULS structural design and strength assessment of a hypothetical 120m long all aluminum catamaran fast ship structure are presented. Important insights and conclusions developed from the present study are summarized. Some of the comparisons have shown that 5383 called Sealium (a patented Alcan Marine alloy) is superior to the standard aluminum alloy 5083 in terms of material properties, ULS characteristics and welding performance. It is our hope that the methods developed from the present study will be useful for ULS design and strength assessment of aluminum multi-hull ship structures.
Investigation on hull deflection and its influence on propulsion shaft alignment
Authors: Šverko Davor
Published: July 2021

As is well-known, tail shaft alignment is sensitive to small disturbances in the vertical offsets of shaft supporting bearings. A major contributor to the bearing offset on board a vessel in operation is the hull girder deflections resulting from changes in the loading condition of the vessel. Therefore the ability to predict hull deflections with sufficient accuracy is of foremost importance in tail shaft alignment design. In order to achieve this objective, ABS has conducted a series of hull girder deflection measurements on a number of vessels of different types and sizes. Collected data are applied to the ABS Shaft Alignment Optimization software to provide a basis for checking shaft alignment design to assess susceptibility to alignment condition changes during the operations of the vessel.

Authors: Pontaza Juan P. , Chen Hamn-Ching , Chen Chia-Rong
Published: July 2021

Vortex-induced vibrations (VIV) is an important design consideration for marine risers in offshore drilling and production. In an effort to better understand the VIV phenomena, we present numerical simulation results for two-dimensional incompressible flow past freely vibrating multi-cylinder configurations found in offshore engineering. Of interest is the response of the structure for low mass ratio, low damping, and high Reynolds number flow conditions. The governing incompressible Navier-Stokes equations are numerically solved and time-integrated using a local-analytic-based discretization procedure, implemented in conjunction with overset (Chimera) grid capabilities for zonal-based resolution of the flow field.

This paper describes the design course organization, the interaction between industry and academia, and example design project results.
A review of the use of CGT for shipbuilding performance measurement.
Authors: Bruce George J.
Published: July 2021

The need for a universal measure of shipbuilding performance has been recognized for many years. To meet the need, the concept of Compensated Gross Tonnes was developed within the OECD, initially as a means of overall comparisons between regions and perhaps nations. Over time, the use has been extended to compare individual companies and also, with a cost element, to compare ship construction costs. More recent work has looked at extending the cgt concept to warship construction. The extended use of cgt as a measure is accepted as less than perfect, but no generally agreed alternative has been proposed. This paper reviews the uses of cgt, highlights some of the uses in measurement of shipyard performance, and proposes alternative means of presenting the cgt information which are intended to improve its usefulness.
Laser Scanning Supporting Graving Dock Retrofit

Published: July 2021

In July 2004, Electric Boat Corporation decided to retrofit Graving Dock 3 at its Groton, Connecticut shipyard with a reinforced concrete wall designed and constructed to replace the existing cellular cofferdams that comprise the dock. Since the cofferdams are of various heights and have deflected in different ways over the years, an efficient method was needed to capture the as-built configuration of the graving dock before design of the wall could be finalized. The owner, design agent and contractor chose a combination of 3D laser scanning, post processing, and CAD modeling to capture this as-built condition. The resulting three dimensional CAD surface model of the dock became integral with the design of the wall and its construction. This paper will provide an overview of the reasons laser scanning was chosen and a description of how the laser scans were taken and processed. The paper will also discuss how a CAD model was created from the processed data, and more significantly, how the model was used in the development of design and construction drawings. The paper will conclude with a look at how 3D laser scanning is being used on other projects at Electric Boat, for both shipbuilding and facilities.
Accuracy and Distortion Control Challenges in Lightweight Structural Unit Assembly at NGSS
Authors: Spicknall M. , Hodges E. , Huang T. D.
Published: July 2021

Shipboard applications of lightweight structures have increased over the past decade in both military and commercial vessels. Severe distortions have emerged as a major obstacle to the cost-effective fabrication of such lightweight structures. With a recent major initiative funded by the U.S. Navy Office of Naval Research, Northrop Grumman Ship Systems (NGSS) has undertaken a comprehensive assessment of lightweight structure technology. This program includes a comprehensive investigation of the fabrication and assembly processes for thin steel structures and their contributions to the final dimensional accuracy and distortion. As part of this effort, substantial work was done to characterize current dimensional quality performance in partial sub-unit (PSU) and combined partial sub-unit (CPSU) assemblies, and to identify contributing factors to dimensional inaccuracy and distortion in unit assembly stages. This information will be used by NGSS as a basis for improvements in fitting and welding processes, jigging and fixturing methods, dimensioning and tolerancing, and accuracy control processes. This paper summarizes the current dimensional quality performance in PSU and CPSU at NGSS, and the contributing factors to current performance.

COGAS Propulsion for LNG Ships
Authors: Wiggins E. G.
Published: July 2021

Propulsion of LNG ships is undergoing significant change. The traditional steam plant is losing favor because of its low cycle efficiency. Medium-speed diesel-electric and slow-speed diesel-mechanical drive ships are in service, and more are being built. Another attractive alternative is combined gas and steam turbine (COGAS) drive. This approach offers significant advantages over steam and diesel propulsion. This paper presents the case for the COGAS cycle.

Authors: Yung T. W. , Ding Z. , Kuo J. F.
Published: July 2021

This paper summarizes a study to investigate the influence of corrugations on tank sloshing pressures. Through well planned and executed test programs, the authors observed enhancement as well as reduction of impact pressures under the complex hydrodynamic interaction between local flow and the corrugations. Engineers should consider the physics of these corrugation effects in defining design pressures for integrity assessment of membrane LNG tanks.

The stern boat deployment system was investigated to evaluate the capability of launching and recovering RHIB via the stern ramp. The main parameters to launch and recover RHIB were tested at the design stage. The combined hydrodynamic effect of the stern wake and the water jet flow made it difficult to maintain the maneuvering and seakeeping ability of RHIB approaching to the stern ramp. The safe recovery course was proposed to maintain the directional control of RHIB and to reduce the combined hydrodynamic effect in the transom zone. To evaluate the feasibility of RHIB recovery, the stern sill depth was measured in various conditions and the ramp availability time was obtained. Also, the experimental PTO test was performed by the number of successive launching and recovering operations.
Environmental Contour Lines: A Method for Estimating Long Term Extremes by a Short Term Analysis
Authors: Haver S. , Winterstein S. R.
Published: July 2021

Design of offshore structures involves the calculation of reliable estimates for loads and responses corresponding to annual exceedance probabilities of 10-2 and 10-4. In order to do so, all sources of inherent randomness must be accounted for, i.e. the short term variability of say the 3-hour extreme value in a given sea state should be combined with the long term variability of the sea state characteristics. This calls for some sort of a long term analysis. For linear or nearly linear problems this can easily be done, while such an analysis becomes more complicated and time consuming for strongly non-linear response problems. The difficulties are greater if a major part of the environmental load is of an on-off nature. This paper illustrates an approximate approach, the environmental contour line method, for obtaining proper estimates of long term extremes utilizing a short term analysis. Examples are also included.

Published: July 2021

There is limited long term service experience with the modern generation of large container carriers and hence there is great interest in improving our understanding of the performance of these vessels. In an effort to assess the actual structural service performance of a large container carrier, a comprehensive full-scale measurement system was developed to measure the wave environment, ship motions and structural response. The system was installed on an 8063 TEU container carrier built in 2006, and the first year measurement campaign has successfully been completed. This paper presents a summary of noteworthy observations during the first year’s voyage records which includes ship motion, wind and wave conditions, and hull girder strains and derived hull girder bending and torsional moments. The observed vibratory responses of the hull girder are also presented.
