Celldelning -Livets process De allra flesta levande celler delar sig. Multicellulära organismer gör det för att bygga upp vävnader eller för att förnya och ersätta skadade celler. Encelliga organismer delar sig för att föröka sig och hålla sin population levande. För att en bakterie ska överleva och föra sina gener vidare måste den dela på sig. Detta sker via en process som kallas binär fissio

Seawater intrusion has been aggravated due to anthropogenic reasons, such as sea level rise and over abstraction of groundwater, which is spoiling the groundwater sustainability. This study focused on a negative hydraulic barrier using a barrier well as a countermeasure. Two lab-scale experiments and a numerical analysis with a 2-D solute transport model were conducted to examine an optimal locati

Conductance was calculated for trapezoidal nanowires with different forms and strengths of imperfection using kwant, a quantum transport software package that uses a tight-binding model. In this thesis it is found that increasing magnitudes of different imperfections such as surface charge and roughness roughen conductance steps, introduce resonances, and lower conductance overall with different c

Introduction: This study was performed to optimize extraction of lead, copper and zinc from seaweed using pressurized hot water, to investigate the selectivity and extractability of the extraction. Background: Pressurized hot water extraction is an environmentally sustainable method in comparison to more common extraction methods, such as distillation or solvent extraction, used with plant mater

Existing studies on the relationship between the insurance market and economic development tend to use empirical methods that rely on the unrealistic assumption of cross-sectional independence. This thesis aims to highlight the drawbacks of this assumption. The results are achieved by comparing the results of the Common Correlated Effects (CCE) model to the two-way fixed effects model as well as t

På Lunds Tekniska Högskola studenter som studerar på programmet Civilingenjör inom Kemiteknik en obligatorisk kurs Energiteknik KETF30. Kursen har ett laborationsmoment om värmeväxling som behöver förnyas. Målet med kandidatarbetet är att få fram en laborationsbeskrivning med fokus på värmeväxlarens beteende beroende på olika parametrar och jämföra de två metoder som kan användas för att beskriva At Lund University, students in the program Chemical engineering have a compulsory course Heat Engineering (Energiteknik KETF30). The course has a laboratory practical concerning heat exchanger that needs to be renewed. The goal of this bachelor thesis was to write a description for the practical, focusing on the heat exchanger’s behavior considering different parameters and comparing the who comm

Introduction: A new method for separation and determination of Glyphosate and Glufosinate alongside their respective major metabolites aminomethylphosphonic acid and 3-(methylphosphinico)propionic acid was found then tested in spiked soil and surface water. Background: Most methods today require derivatization for determination and separation of these compounds. Methods without derivatization rel

Juvenile delinquency has become an obvious and recurring issue in the daily debate and emerges as one of the most controlling and dominant societal problems. There are various reasons why people choose to commit crime and there is no easy answer to the question why young people commit crime. A fundamental but crucial distinction to be made regarding crime is the difference between deviant acts and

The main purpose of this study is to research how an organization can develop, implement and measure the effect of employee well-being strategies to ultimately boost the organization’s bottom line. In this exploratory case study, SAP served as the case of investigation and primary data was collected through six qualitative interviews. The sample included SAP representatives from different levels o

This paper examines the different attitudes that the police and private security officers in Sweden have towards a proposed change of legislation, recommended by The Swedish Police Authority. This proposal suggests that some functions and powers of the police would instead be given to the private security guard employed in the private security sector. It also examines the collaboration between the

At the core of the sustainable solid waste management challenge lies increasing rates of consumption which contribute directly to problems of resource extraction and degradation. Recycling is a tool designed in part to address this problem of scarcity, however on its own it is not enough to solve the problem, particularly in relation to plastics, which are challenging to manage and often are not r

Den här studien undersöker de sociala och legala normerna kring poliser som har blivit utsatta för hot och våldsbrott i tjänsten. Studien är baserad på tre olika data material bestående av intervjuer med svenska poliser, dokumentanalys av rättsfall från svenska tingsrätter samt dokument från Brottsoffermyndigheten. Genom att modifiera Nils Christies teori om det ideala offret till att passa bildenThis study researches the social and legal norms surrounding police officers who have become victims for threat and violence crimes in the line of duty. It is based on three different data materials consisting of interviews with swedish police officers, documentanalyze of Swedish court documents and documents from The Swedish Crime Victim Compensation and Support Authority. By modifying Nils Chris

Monte Carlo event generators are used by theoretical particle physicists to get a better understanding of the phenomena in particle physics. Given the improvements in precision and accuracy of event generators, using these tools can be very CPU intensive. A method of unweighting events using artificial neural networks is presented to improve the efficiency of event generation. An introduction to m

Utmaningar och möjligheter kring laddinfrastruktur i en mindre kommun i södra Sverige. Var ska laddstolparna sitta och vilka betalningsmodeller kan fungera här? När det kommer till implementering av laddinfrastruktur är det viktigt att den är kommunanpassad. De val av platser som görs samt vilka betalningsmodeller som väljs är helt beroende av kommunens förutsättningar. Uppsatsen är ett arbeteThe development surrounding electric vehicles has made a leap forward in the last two decades. More and more people buy electric vehicles, especially cars, both around the world and in Sweden. To accommodate the rise in electric cars, governments and municipalities need to invest in charging infrastructure. This study was conducted in collaboration with Klippans municipality in southern Sweden. Th

Läckor i dricksvattenledningar kostar stora summor pengar och orsakar mycket besvär för samhället. Nya mikrobiologiska analysmetoder har visat sig kunna korta analystiden betydligt – utan att äventyra kvaliteten. Mikrobiologiska analyser av dricksvattnet gör ofta att det dröjer länge innan vattnet i vattenledningarna återigen kan användas efter läckor och underhåll. Detta examensarbete har undersöFaster methods of analysing microbial drinking water quality after pipe breaks or new pipe installations would have beneficial implications. This thesis investigates the use of flow cytometry and cultivation-based techniques in connection to maintenance works, and how flow cytometry can aid in the decision-making around putting drinking water pipes in operation. Previous work has not used online f
