Phosphate ester hydrolysis is fundamental to many life processes, and has been the topic of substantial experimental and computational research effort. However, even the simplest of phosphate esters can be hydrolyzed through multiple possible pathways that can be difficult to distinguish between, either experimentally, or computationally. Therefore, the mechanisms of both the enzymatic and non-enz

Recent experiments at the Brazilian Synchrotron Ligth Source (LNLS) Ultra Violet and X-Ray beamlines are pushing on the Synchrotron Radiation (SR) beam position stability requirements. In the direction of having photon Beam Position Monitor integrated to the orbit closed loop control system, we developed a staggered blades XR BPM and a four-channel current measurement electronics. The BPM mechanic

This study presents and analyses search strings and user data for different Swedish lexicographical websites. The underlying empirical material was sourced from two relatively new websites, www.saob.se and the joint dictionary portal www.svenska.se, which collects and provides a single point of entry to three Swedish monolingual dictionaries financed by the Swedish Academy. Statistics are presente

Antalet äldre med komplex sjukdomsbild ökar i Sverige och de är en stor grupp som vårdas inom slutenvården. Vårdens resultat och följsamhet till vården ökar om patienterna känner sig delaktiga. Forskning visar dock att patienterna inte känner sig delaktiga. Syfte: Att beskriva vad sjuksköterskor inom slutenvården upplever för hinder för äldre personers delaktighet. Metod: Studien gjordes med semisElderly persons with multiple diagnoses are increasing in Sweden and they are a large part of the inpatients each year. Hospital care and patient compliance are both improved with patient participation. Studies show however that patients does not feel that they participate in their own care. Aim: To describe what nurses in hospitals experience for type of difficulties concerning participation of e

This paper investigates the journalistic language in El País, Spain’s most read newspaper, with the aim to problematize the use of male generic nouns in Spanish. According to our theoretical framework, the feminist critique of language, male generic nouns are considered to be the result of a patriarchal and androcentric system. Thus, the analysis studies how and to which extent the usage of male g

Syftet med denna rapport är att göra en brandteknisk riskvärdering av Falkenbergs ishall och utvärdera det befintliga brandskyddet med avseende på personsäkerhet. Arbetet ingår i kursen Brandteknisk riskvärdering (VBR054) som ges av Avdelningen för Brandteknik vid Lunds Tekniska Högskola. Falkenbergs ishall är belägen i Kristinebergsområdet i Falkenberg. Byggnaden omfattar 3500 m2 och används av iThe aim of this report is to perform a fire safety evaluation in terms of personal safety of an ice hockey arena located in Falkenberg. The building consists of an ice hockey rink, bleachers, changing rooms and some storage areas and is used by schools, sport clubs and the public. To identify fire scenarios that would challenge the building an initial risk analysis was performed. Three fire scenar

In this thesis, the functionality of existing Crazyflie models is extended to include current implementations of attitude and velocity control. The models are validated both as individual agents and as a swarm through comparisons of swarm behaviour during step, ramp and frequency response testing. The models are found to accurately replicate the dynamics of the real system, but additional research

Internenet och humor är något som historiker sällan undersöker. Detta främst då dessa skapar problem med hur man bör ta sig an dem. Frågor om detta skapar ett avvaktande från professionella historiker vilket i sin tur skapar ett problem då många intressanta frågor väcks om man som historiker verkar på internet. Det går att se en typ av material på internet med en tydlig koppling till både humor oc

This report deals with the problem of learning to classify observations from a mixture of random variables. The distributions of the random variables are of known functional forms but with unknown parameters.

This problem is equivalent to that of determining separating hypersurfaces in the range of the random variables. Any rule of classification will be a function of random variables and

This report focuses on CFD-calculations using parallel processors carried out with the software Fire Dynamics Simulator (FDS). From a users point of view the advantages and disadvantages with parallel CFD-calculations were analyzed and evaluated. A simplified me-thod for quantitative evaluation was developed with guidance from ASTM E 1355 whereu-pon relative differences between serial reference sc

There are several accident investigation methods and they are used in a wide range of fields. However, the methods have not been used so much in the fire accident area. In the present thesis, the methods’ capability to investigate fires and what they result in are explored. In addition, answers are given concerning how important the background information is for their applicability. First, a selec

NTRU is a public-key cryptosystem, where the underlying mathematical problem is currently safe against large-scale quantum computer attacks. The system is not as well investigated, as for example RSA, and the company behind NTRU has created the NTRU Challenges, to remedy this. These challenges consist of 27 different public keys of increasing size, where the task in each challenge is to calculate
