We present a summary of the commissioning and performance of the vacuum system of a 500-MeV booster synchrotron recently built at LNLS as part of a new injector for the LNLS light source. The main vacuum parameters of the synchrotron are pressure below 5×10-7Pa (lifetime of 1-2 hours), no in-situ baking, no cooling system, and a short recovery time after ventilation. All parts of the system are ma

In the context of the European Commission’s work to further the EuropeanGreen Deal, Executive Vice-President Maroš Šefčovič requested theEuropean Group on Ethics in Science and New Technologies (EGE) to issuea series of three Opinions providing ethical perspectives on different aspectsof the green transition.The Scoping Considerations provided by the Vice-President note that thequestions raised by

We present results of the commissioning of a new injector for the Brazilian Synchrotron Light Source. The new injector consists of the existing 125-MeV LINAC and a new 500-MeV booster synchrotron. At present, about 40 mA can be injected into the booster and about 15 mA can be ramped up to 500 MeV at a repetition rate of 0.17 Hz. The new injector has allowed the accumulation of up to 540 mA in the

An appealing procedure to obtain operating pressures in the 10-8 Pa range, which is necessary for the insertion devices elements of synchrotron sources, is to coat the inner ultra-high vacuum chamber walls with a thin film of non-evaporable getter (NEG) metals. Titanium, zirconium, vanadium, and their alloys are used as NEG materials due to their low activation temperature, high chemical activity,

The substrate preparation for CVD diamond growth is of basic importance due to several reasons. A new molybdenum substrate preparation method, the aluminum oxide abrasion jetting, is introduced and compared with the traditional ones. Raman Scattering Spectroscopy (RSS) and Scanning Electron Microscopy (SEM) characterize CVD diamond films. CVD diamond films of good quality and uniformity were obtai

"Man kan fråga sig varför de som otvivelaktigt har makt att påverka samhället lockas så pass av satiren. De har ju redan makten att påverka på andra sätt.” Det skriver medieforskaren Joanna Doona, författare till Det politiska skrattet: satir och medborgarskap, apropå debatten kring sverigedemokraten Richard Jomshofs spridande av muslimfientliga bilder.

With the shift towards renewable energy, the need for effective energy management grows. Renewable sources introduce variability and unpredictability, leading to volatile energy prices that expose consumers to fluctuations. To mitigate costs, energy storage and forecast models for electricity and thermal energy can be used to make optimal decisions on when to purchase energy from the grid. This th

Peptides constitute alternative molecules for the treatment of infections caused by bacteria, viruses, fungi, and protozoa. However, their therapeutic effectiveness is often limited by enzymatic degradation, chemical and physical instability, and toxicity toward healthy human cells. To improve their pharmacokinetic (PK) and pharmacodynamic (PD) profiles, novel routes of administration are being ex

Background: More than 10% of the global population has a BMI above 35. Bariatric surgery is an efficient way to treat this condition. Unfortunately, there is a risk of nutritional deficiencies. The number of studies after a longer time span is scarce. The aim of this study was to determine the occurrence of anaemia five and ten years after bariatric surgery and how it was related to substitution t

The purpose of this study is to map Key Performance Indicators (KPIs) related to the operation and maintenance of photovoltaic (PV) systems, i.e., solar cells, on commercial buildings. This is investigated through a literature review aimed at gathering and evaluating relevant KPIs. A total of 24 KPIs are identified in the literature review. After evaluation, a selection of these KPIs is used to an

Hearing loss is increasing with an ageing population. There is thus a need for more convenient diagnosis methodology. This thesis investigates whether it is possible to classify age-related hearing loss using speech biomarkers and Automatic Speech Recognition (ASR) or not. The methodology was a binary classification problem based on analysing conversational data between a participant with normal h

This thesis investigates the causal relationships among alarms at the European Spallation Source (ESS), focusing on enhancing alarm management through advanced data analytics. The study explores these relationships using Dynamic Bayesian Networks (DBNs) complemented with well-defined Conditional Probability Distributions (CPTs). This approach models the cascading interactions of alarms based on th

Ever since the end of the second world war, Europe has been lagging behind the United States in rocket development. In particular in the last 10 years, the technological gap and American competitive advantage have grown thanks to SpaceX’s development of reusable launch vehicles. A key enabler for the reusability of booster stages is precise rocket engine control. This thesis addresses the objectiv

Today, most software systems are event-driven, meaning that code execution is triggered by events handled dynamically. A typical example is a graphical user interface, where a button click initiates a specific action. In contrast, classic automation systems rely on programmable logic controllers, which execute code periodically at fixed intervals. The purpose of this study is to compare periodic a

BACKGROUND: HIV viremia has been considered a cardiovascular disease (CVD) risk factor, but many studies have had insufficient data on potential confounders. We explored the association between viremia and CVD after adjusting for established risk factors and analyzed whether consideration of viremia would improve CVD prediction.METHODS: Adults from RESPOND were followed from the first date with av

The IFMIF-DONES Facility is a unique first-class scientific infrastructure whose construction is foreseen in Granada, Spain, in the coming years. Strong integration efforts are being made at the current project phase aiming at harmonizing the ongoing design of the different and complex Systems of the facility. The consolidation of the Diagnostics and Instrumentation, transversal across many of the

Automation and robotics have been widely integrated across various industries, yet the building sector has not seen significant evolution over the last few centuries. This thesis presents a concept for integrating automation at construction sites, specifically for the assembly of wooden prefabricated walls. When working with wooden prefabricated house elements the sizes are typically large, 6-10 m

The efficient allocation of flexible resources, such as grid batteries and wind parks, across multiple energy market auctions, is pivotal for maximizing socio-economic welfare, interpreted here as profits. This study explores various optimization methods, including Linear Programming, Integer Linear Programming, Robust Optimization with Linear Programming, and Robust Optimization with Integer Line

This thesis examines how elastic deformations affect the kinematics and stationary positional and orientational accuracy of an industrial manipulator. The analyzed robot had a wrist design which introduced a coupling between the two wrist joints, i.e., the outermost two joints responsible for orienting the end-effector. This meant that one of the wrist motors had an effect on both joints, and that
