No full textThe purpose of this study is to perform the techno-economic analysis of photovoltaic system utilization for lighting and cooling of Ferry Ro/Ro 500 GT. The world is facing a dilemma of increasing dependence on fossil energy with decreasing supply. This situation must be anticipated by all sectors by energy efficiency (EE) and utilizing renewable energy (RE). Especially for RE in the transportation sector, ships as consumers of oil energy can also take advantage of solar energy sources, for example for lighting and cooling. For that purpose, five steps must be taken. First, determine the design specifications. Second, determine the specifications of components of the PV system. Third, calculate the power required for lighting equipment. Fourth, calculate the power required for the cooling system. Fifth, make an investment comparison for propulsion systems between diesel engines and photovoltaic systems. The results show that the energy required for lighting and cooling system as well as for propulsion systems can be placed in the deck area of 148.8 m2 for all system components, such as; PV modules, charge controllers, batteries, and inverter. This study can provide an overview of the use of PV system in designing the environmentally new or renovation ships
Raising public awareness and knowledge of diagnostics of oncological disease prevention programs in Lithuania.
No full textIt is imperative to inform the society about free preventive oncology programs. It is a must to nurture society’s knowledge and consciousness, in order for patients to actively partake in preventive oncology programs, as well as highlight the populace’s responsibility over their own health. In order to assure the quality of prevention programs, it is important to determine society’s consciousness and knowledge. Research purpose: to determine society’s consciousness and existing knowledge about the diagnostics of preventive oncology programs in Lithuania. Research methodics: A quantitative analysis has been done – an anonymous questionnaire has been given out, one which was constructed based on practice and scientific literature, exploring society’s consciousness and knowledge about the diagnostics of preventative oncology programs. The quantity of the research was concluded from 400 respondents. The research was done in Vilnius, Kaunas, Klaipėda, Šiauliai and Panevėžys private X health care establishments, and upholding all the principles of ethics. In order to submit the results of the research, descriptive and statistical data analysis methods were used. To analyze the questionnaire data „SPSS 26.0“ and „Microsoft Office Excel 2016“ software packets were used. Research results: the respondents lack consciousness over the active participation in preventative oncology programs, the respondents think that preventative programs are unnecessary, they feel good, therefore find no need to go for regular check ups. In the opinion of respondents, the tests are too costly, and the procedures could potentially cause side effects. Most of the information about the preventative programs respondents get from their family doctor. The researched group thinks that the encouragement of the family doctor, some benefits to the health and more detailed information about the programs would motivate the more active participation. Women and men have valued their knowledge positively about the preventative oncology programs. Depending on their residential county, women lack knowledge about the frequency of breast cancer prevention programs, and only the fifth of all women know about the cervical cancer frequency, and which age groups are eligible to partake in the program. The respondents with a higher education level had more knowledge about the colorectal cancer prevention program's periodicity. It has been determined that married men knew most about the eligibility of the age groups for prostate cancer. Conclusion: The society lacks consciousness and knowledge about preventative oncology programs' diagnostics in Lithuania. Keywords: preventative oncology programs, society’s consciousness, society’s knowledge, oncological diseases
Lithuanian combat divers squad activities in 1990–2004.
No full textLithuanian historical sources mentioned the divers for the first time in the 1990s. With intention to assist emerging national formations of the Department of National Defense of Lithuania, , Valerijus Krisikaitis reported to the local national defense department in Klaipeda in September of 1990. He was a certificated diver and karate instructor and expressed his desire to work in the national defense service. Also, he had displayed an unorthodox approach by offering to organize and train a squad, which would be prepared for combat self-defense and combat diving. These skills could be applied to protection of Klaipėda Seaport again possible attacks organized and executed by foreign hostile military forces. This was the beginning of the formation of combat divers’ units in Lithuanian military. Currently, this combat capacity has increased significantly. Due to "Restricted" and "Secret" classification marks, the exact figures cannot be disclosed, but open sources indicate that there are two separate units, The Underwater Action Team, which is part of the Naval Forces and the Combat Divers Service, which is subordinated to the Special Operations Forces. These units have separate boat crews, maintenance and supply teams, individual explosive ordnance disposal experts, combat divers, rescue teams and much more. The structure of research in the master 's thesis consists of a summary in English, an introduction and three chapters. Also, it includes conclusions, list of literature and sources, recommendations and appendices. The first chapter analyzes the key aspects of formation and origins of the Lithuanian Army Combat Swimmer Squad in 1990-1992, the incorporation of combat swimmers into the Lithuanian Armed Forces and the squad contingent formation instructions, divers and possibilities of starting / financing / supplying the technical base. The second chapter is concentrated on the activities of the Lithuanian Combat Swimmers Squadron in 1993-2004. Separate chapters discuss the change of the Lithuanian Armed Forces 'leadership in terms of combat swimmers' platoon and the planning of the platoon employment, the genesis of the Lithuanian Armed Forces 'combat swimmers' platoon competence building system and its transformation. Also, evolution of the technical base of the Lithuanian Army combat swimmers' platoon: financing and supply. The third chapter examines the image of Lithuanian military divers in media in 1991–2004. The main aspects and narratives that need to be paid attention to: the Lithuanian society (media) in relation to Lithuanian combat swimmers are analyzed. It is examined why Lithuanian combat swimmers benefited from media attention. The goal of the research. The main goal of the research is the information analysis of the Lithuanian combat divers’ activities during formation of the independent and modern Lithuanian military structure. This analysis includes available sources from the Lithuanian military and public media related with the topic. The methods of the research. The main research was performed applying combined study using both qualitative and quantitative methods of research. The main tools utilized in the research were the questionnaire and in-depth interviews. Statistic data processing and the content analysis methods had been applied in order to process the data collected. The target audience of the qualitative research were 7 individuals who had completed military service in the combat divers’ unit in the past. The research was conducted according to the ethical standards. The results of the scientific research. The analysis of the data revealed that Lithuanian combat divers have been perfectly prepared to act as soldiers, both physically and psychologically, during the timeframe of this research embracing periods of 1990s to 2004. Their activities were limited only due to the financial constraints and lack of the reliable diving equipment and infrastructure. The importance of the combat divers in the Lithuanian Armed Forces has been significant since the beginning of their activities and was slowly increasing during the time period of the research. This was mostly attributed to their skills and abilities to perform demolition tasks underwater and this field of activities was equally high skilled in comparison to modern and highly equipped foreign military forces and their divers. The age and education of the potential candidates to the Lithuanian combat divers’ unit also had a great significance. Because training and preparation process of the candidates could take years, only young soldiers from the professional military service units have been accepted to be trained as highly professional combat divers. According to the interviewees, the significance of the Lithuanian combat divers was definitely high in the Lithuanian military because a small unit of underwater subversive divers could cause a greater damage than an infantry battalion. Conclusions and recommendations. 1. The origins of formation of the Lithuanian combat divers‘ squad in 1990s. Back at that time, the leader and main instructor of the combat divers‘ unit Valerijus Krisikaitis had started to recruit the team and train the diver candidates. There was a clear vision at that time that independent Lithuanian Armed Forces would meet the demand of the highly trained combat divers. The problem of the incorporation of the unit into the structure of Lithuanian Military Forces has been addressed gradually. In the beginning the combat divers under the name of the diving club “Nautilius“ were incorporated into the local SKAT department in Klaipėda. In 1992, after the establishment of the “Iron Wolf“ brigade and the paratrooper regiment in Klaipėda, the combat divers became subordinated to the regiment commander. Due to insufficient funding during the period from 1990s to 1992, there were active efforts in order to find necessary funding from both private supporters and the government. 2. The position of the senior leadership of the Lithuanian Armed Forces towards the issues of the Lithuanian combat divers had improved since 1993. It was the beginning of the actual support and assistance. Orders had been issued to establish a squad of combat divers. The support has been growing ever since due to the fact that the necessity of this unit had been proved and there were no uncertainties about the quality of training. Overall formation of the Lithuanian Armed Forces and incorporation of the combat divers took more than a few years. Time was necessary for training of the candidates able to perform combat tasks, special operations, reconnaissance and demining tasks both underwater and on the surface. During the period of 12 years since 1992, the training system was implemented from the scratch. The heart of the diving training became the squad of combat divers in Klaipėda, led by Valerijus Krisikaitis. The Lithuanian Armed Forces during the period from 1993 to 2004 had become capable of training the combat divers and explosive ordnance disposal experts in their own local training centers. These locally trained combat divers have been internationally acknowledged as perfectly prepared to perform combat tasks and being able to train other soldiers to perform diving tasks. A positive change in Lithuanian legislative and executive powers‘ opinion towards the Lithuanian combat divers led to increase of both, reliance and funding. The undisputed importance of the only diving unit able to perform underwater countermining was the main reason that caused such a trust. Back in the period from 1993 to 2004, the territory of the Republic of Lithuania had been covered by unexploded ordnance items left after World War II and still causing threats to the local inhabitants. 3. After the restoration of the independence, Lithuanian media has been used effectively in order to create a positive public opinion about the activities of the combat divers. The soldiers who have been doing their service in the unit have been portrayed as brave and professional specialists doing underwater countermining and other secret military tasks. The main aspects and the common narrative in the media and the public eye were the combat training of the divers, also training in the public sectors, assistance to the rescue services and their contribution to the society. The content of the media publications has changed. In the beginning, the main topic was the issues of the combat divers‘ service, mostly the financial scarcity. Invitations to join the diving club “Nautilius“ and information about private and commissioned diving tasks performed by the unit had been published. Since 1997, the media had changed earlier used kind of publications into information about the international military trainings attended by the Lithuanian combat divers and their autonomous training. The invitations for the civilians to join the combat divers‘ service disappeared from the media and were replaced by the publications about well-trained divers and their professionally carried out underwater tasks that demonstrate the competence equal to the modern foreign military divers
The interinstitutional cooperation in providing assistance to families at social risk: the case of Šilutė District.
No full textInter-institutional cooperation in social work with families at social risk is understood as a well- coordinated system of cooperation focused on solving the complex problems experienced by the family, taking into account the totality of the interaction processes in the service network, ensuring that clients receive the necessary, accessible and effective services. The aim of the research is to find out how representatives of different institutions understand the content and meaning of inter-institutional cooperation in providing assistance to families at social risk. The objectives of the research: To analyse the concept of inter-agency cooperation in the context of family social assistance. To reveal the significance of institutional cooperation in the development of cooperation through the social network approach. To provide an overview of the legal framework for institutional cooperation in social work with families. To examine the development of cooperation between the municipal institutions in Šilutė district providing services to families at social risk at the level of Šilutė district. The methods of the research: analysis and summary of scientific literature, statistical data and legal documents. Semi-structured interview method was used for the qualitative research. Content analysis method was used for data processing. The research sample consisted of: 11 professionals from different institutions from social services, social assistance, child rights protection services, health, education, law enforcement, and NGOs. Results of the research. Inter-institutional cooperation is indicated as a method that helps to systematically assess the situation of families at social risk, sharing information, working in a team more effectively solves family problems. The emphasis is on formal cooperation to exchange relevant information and to sign a family support plan during case manager meetings. It was revealed that not all stakeholders in the support network are equally involved in the process of cooperation, there is a lack of mental health services in the district, and many informants would like to see more active forms of cooperation and more coordination of the cooperation system. Conclusion. The benefits of institutional cooperation are highlighted, but the effective results of inter- institutional cooperation in working with families at social risk are hampered by the gaps in the coordination of the process, the need for missing services in the district, and the problems of interaction resulting from the lack of motivation and involvement of professionals
Mechanisms influencing particle depletion in and around mussel farms in different environments /
No full textThrough the mechanisms of particle immobilization and subsequent depletion of particles, mussel cultivation has a direct effect on chlorophyll-a concentrations and Secchi depth; both of which are primary indicators of marine ecological status and metrics for water quality management. As such, mussel cultivation has been proposed as a measure to mitigate the effects of coastal eutrophication. However, the extent to which this ecosystem service, and relatedly, biomass accumulation, are affected by ambient environmental conditions involves complex interactions. To explore the interacting mechanisms underpinning depletion dynamics under various biophysical conditions along the salinity gradient in the Baltic Sea, we used an updated Dynamic Energy Budget (DEB) model with field data from the western Baltic Sea, accommodating osmotic stress. We use the DEB model to drive a 3D farm-scale model within a novel precompiled hydrodynamic framework (FlexSem) to evaluate the effects of different environmental conditions and farm configuration on the intensity and extent of the chlorophyll-a depletion signal. We also report on extensive in situ monitoring of chlorophyll-a and Secchi depth within and around mussel farms, from several cultivation areas from around the western Baltic Sea to evaluate site-specific characteristics of depletion. Monitoring reflected the high degree of spatio-temporal variability in the quantification of this ecosystem service; with relative differences in chlorophyll-a from −14 to 69% and Secchi depth from 0 to 75%. We find that the extensive in situ measurements in different environmental conditions can be represented by the integrated farm model in terms of mussel biomass accumulation and depletion, providing insight on the interactions of current velocity, farm orientation to predominant current direction, ambient chlorophyll-a concentrations, and total biomass loads on the intensity and spatial extent of the depletion signal. Furthermore, the model has been calibrated to cover a variety of environmental contexts and permits fine-resolution simulation of multiple environmental interactions on mussel energetics, which can be used to evaluate potentials for optimizing mussel mitigation culture and the associated ecosystem services of phytoplankton depletion under local conditions without extensive recalibration from field growth data. The general interactions exhibited here and model will be useful for evaluating depletion and planning the establishment of mitigation farms in regions where national environmental monitoring programs can provide basic data. This can also reduce the need for extensive and costly in situ monitoring programs
