Risks Related to the Maritime Transportation of Oil and Gas (mainly Crude oil, LPG, and LNG) -A Conceptual Study and Empirical Outlook on the Baltic Sea and UK Territorial Waters to Mitigate Risks

Transportation of oil and gas by the Sea characterizes challenges from a safety viewpoint. In this type of transportation, different sizes of special tankers carrying oil and gas. The marine transportation of these scarce natural riches is involved with risks and hazards, which may lead to many losses; for instance, wasting oil and gas, injuries of people, damaging ships and properties, and damaging environment. The main purpose of this thesis is to evaluate the risks, hazards, and accidents during transportation of oil and gas (mainly Crude Oil, liquefied petroleum gas, and Liquefied natural gas) by the Sea with concentrating on transport safety. Hence, a better understanding of these risks and hazards can contribute to decrease of addressed losses.This study is carried out on risks associated with maritime transportation of oil and gas starting with describing the general casual chain (dealing with causes, incidents, accidents and consequences/causalities), continuing with describing risk analysis techniques (including event tree analysis and fault tree analysis) and risk control measures/options, and finally implementing aforesaid investigations on real data from two areas; namely UK territorial waters and the Baltic Sea.In this study, the results of analyzing data from 1991 to 2010 in UK territorial waters revealed that collision and grounding were two most common accidents in terms of crude oil tankers, LPG and LNG carriers in which 44% of all accidents were equally divided between collision and grounding.

Långtidsuppföljning och artrosutveckling hos hundar kirurgiskt behandlade för ruptur av kraniala korsbandet :

The high incidence of cranial cruciate ligament injury in dogs results in both suffering and significant costs due to treatment and care of affected dogs. Today there are several different technics for surgical treatment in dogs with ruptured cranial cruciate ligament. At University Animal Hospital (UDS), SLU, in Uppsala two fundamentally different methods; TPLO (Tibial Plateau Leveling Osteotomy) and external fixation with suture material are practiced. The aim of this study was to estimate if the different surgery technics result in any difference regarding the function of the dog in a long term perspective. Since motion and function are very affected by arthritis, was the purpose also to determine if there are any differences in developing arthritis between dogs surgical treated with external fixation respectively with TPLO. Development of arthritis is common after surgery or traumatic injuries in a joint, such as cruciate ligament rupture. Unfortunately was the number of dogs in the study to small to achieve two comparable groups.

Mekaniserad ungskogsbehandling för röjning och skörd :

Earlier attempts at mechanising pre-commercial thinning have been met with varying degrees of success. Most attempts have been based on techniques where residual stems are straddled. Early treatment is essential to limit damage on residual trees. One part of the present study is an evaluation of mechanised pre-commercial thinning using the new Vimek 404R. Vimek 404R is a fairly small machine that permits selective removal of stems, making it potentially suitable also for areas overdue for pre-commercial thinning. The study established the level of performance for the machine, as well as the improvement needed to make it an economically viable option.

Planering och projektering för individuell mätning och debitering i flerbostadshus

The study aims to reduce energy consumption in apartment buildings where individual metering and charging of heat is applied. The aim is to develop planning and design for individual metering and charging in apartment buildings.The study is based on literature review, interviews and case study that include analysis of existing documents. Interviews were carried out with the property developer and the involved consultants who planned the apartment building Yasuragi. To investigate the differences the condominium association has noted in heat consumption between flats, the debit values of the heat were used to discern which houses that were furthest from the average consumption. On these flats there were temperature measurements and thermal photo shoots made for discriminating behavior and possible construction techniques which could be the explanation for the heat spread.Boverket shows that the consumption of heat can be reduced by 10-20% after insertion of individual metering and charging in an apartment block.

Apputveckling : En studie av motsättningar mellan design- och användningspraktiker ur ett verksamhetsteoretiskt perspektiv

We live in a high tech era of electronic media, which is changing our lives (Giddens, 1999). Apps are examples of technologies that affect our lives. An interesting question in this context is what apps will have for significance; on one hand for the development of technology, and on other hand for humans? relation to technology. Since the development and change process are central issues in the science of education I will explore the development of applications.

Solenergi på Kvarnholmen

In recent years it has become more and more evident that man has contributed to much of the climate changes that have taken place during the last century. A major challenge today is to reduce emissions and energy usage at the same time as the global population is growing. To contribute to a better environment, Stockholms Stad has set at target of becoming fossil fuel free by the year of 2050. The construction of new districts is done with this goal in mind; energy efficiency and renewable energy sources are examples of methods to achieve this.Solar energy is considered to be a sustainable energy source and the most common techniques to harvest solar energy in Sweden are solar cells and solar collectors which produce electricity and heat respectively. This report aims to investigate whether an investment in any of these systems would prove to be economically beneficial at Kvarnholmen, a district under construction in eastern Nacka, Stockholm.Since the finished blueprints only cover a small portion of Kvarnholmen, the report examines the possibilities for a house where construction has already begun, Nya Kvarnen.

Mellan fri vilja och datadriven exploatering: En studie om drivkrafter, medvetenhet, makt och ansvar inom onlinecasinomarknaden

This essay examines the limits of marketing strategies in the online casino industry, focusing on how data-driven and advanced marketing practices influence consumer behavior and contribute to problematic gambling consumption. By observing the online casino industry, the study identifies how companies use sophisticated data analysis methods and psychological techniques to attract and retain customers, raising significant ethical and social issues. The study highlights three key perspectives: the consumer's, the producer's, and the legislator's. From the consumer's perspective, it explores how various consumer behaviors, from responsible gambling to problematic overconsumption, are influenced by marketing and gaming experiences. This includes an analysis of how cognitive limitations and psychological biases can lead to irrational decisions and an increased risk of gambling addiction. From the producer's perspective, it examines how gambling companies use marketing strategies and technologies to increase profitability and what incentives they have to take social responsibility according to modern Corporate Social Responsibility (CSR) principles. It appears that companies do not see CSR as a business goal beyond the risk of current and future regulatory compliance requirements and policy changes. From the legislator's viewpoint, the current regulatory framework for the gambling industry is discussed, including the changes that occurred in 2019 when the special monopoly form we had in Sweden was transformed into a license market.

Myten om jämställdhet : En kvalitativ studie om hur det svenska rättsväsendet befäster en ojämlikhet mellan könen

The purpose of this paper is to examine the law regarding gross violations of women and its application in the Swedish legal system. We have investigated how the legal system takes into account a holistic perspective of the vulnerable situation of women in the investigation and assessment and the extent to which psychological violence in the form of verbal abuse, threats and harassment attention. We also wanted to find out how the law's design may contribute to difficulties in the implementation and interpretation of it. In this study, we used a qualitative research approach when we decided to conduct an interview with a police officer and a textual analysis of four cases from the district court. Interview questions were semi-structured in order to gain a deeper understanding of the phenomenon.

Salmonella prevalence in the poultry feed industry in Pakistan

Abstract One of the leading causes of food borne infections in the world is due to Salmonella by con-suming poultry products including eggs and meat. According to US Food and Drug Admin-istration (2009), 2 to 4 million cases of Salmonellosis in humans occur every year only in US. Salmonella causes wide range of diseases with enteric and typhoid fever, food poisoning, di-arrhea and gastro-enteritis. Many serotypes of Salmonella do not have host specificity and cause disease in all kinds of animals and humans. Salmonella has capability to modify accord-ing to the changing environment and it can develop resistance against routine elimination practices of sanitation, chemical treatments and antibacterial drugs. Newly established poultry industries in Pakistan are confronting various infectious diseases including Salmonellosis while in Sweden Salmonella prevalence in animal products con-sumed for humans is extremely low.

Fröplacering vid hög såhastighet - Väderstad Rapid jämfört med Amazone Cirrus

In today's agriculture efficiency and the capacity of tools and machinery are crucial. In this work we investigate whether it is possible to enhance the capacity of sowing by increasing the work speed of seeders, how seed technology affects seed placement, and if there is any difference between two different brands of seeders and their sow techniques. The seeders we have chosen to compare are Väderstad Rapid drill and Amazon Cirrus drill. The tillage capacity of the seeders and their traction power needs were examined as well.Väderstad Rapid and Amazon Cirrus were tested in a randomized block design with four replicates at three different speeds, 8 km/h, 12 km/h and 15 km/h. The seed placement at the different speeds was examined by dividing the seedbed into four different zones from its surface to its bottom.

Kravspecifikation för en knapp till ett automatväxlingskoncept

This thesis deals with the development of a specification regarding a push-button, which will be used to control the gear-shifting function in an automobile. In addition to this the author will describe different techniques and theories that have been helpful in achieving data and results for the specification.Kongsberg Automotive AB, is located in Mullsjö, Sweden, the company supplies parts to the automotive industry. In the research and development department, R&D, there is a group that works with development of Shift-By-Wire systems. In an automobile with a Shift-By-Wire system the communication between the gear-shifter and the gear-box occurs electronically. The mechanical link is, in most cases, taken away and replaced by the digital system.

Passivhus - lönsamt eller ej? : En jämförelse mellan ett passivhus och ett konventionellt hus

As a result of increased energy prices more and more energy-efficient homes are coveted. An energy-efficient alternative is passive houses, which is characterized by an extremely well insulated building envelope that recovers the heat without the use of radiators or under floor heating. But a passive house requires a higher investment cost than a conventional building project, since it will require more construction materials, training of construction workers, greater land area, and long construction period. But the lower operating cost expects to pay back the higher cost of investment. We therefore question how profitable a passive house is in relation to houses built according to modern conventional building techniques.The aim of our study is to investigate the viability of passive houses compared to convent­ional houses.

Stadsodling : möjligheter och begränsningar

Urban farming can be viewed in several contexts. The first part of this work brings up the beneficial effects of farming on our physical and mental health, knowledge as well as on social life in cities. The introduction of gardening in schools can contribute to an increased awareness on both agricultural practices and importance as well as ecological processes. It can also be used in teaching of other subjects. Farming can also contribute to improving the household economy, and the economy on a municipal or national level.

Smärta hos djur :

We have made a litterature study about pain in animals. In this studie we have brought up areas like sign of pains in animals, pain relief and the care perspective. Pain is perceived when body tissue is damaged or nearly damaged by stimuli. Nociceptors, which are receptors placed at nerve endings, responds to a provocation of pain and transmit an impulse along the nerve to the brain via the spinal cord. Pain is urgent or chronic, and can be divided into nociceptive pain (somatic pain and visceral pain) and neuropathic pain. Different pain mechanisms can arise, such as referred pain, which is when signals of pain are referred to other parts of the body.
