Vid konstruktion av bullerskärmar så väljs vanligtvis pålning som grundläggningstyp. Det finns flera modeller som kan approximera ett krav på minsta pållängd beroende på olika typer jordförhållande och vindlast. Om pålen ska placeras vid en slänt blir dock beräkningarna betydligt mer osäkra då inverkan av en slänt på den horisontella stabiliteten är svår att uppskatta. Denna rapport har analyseratWhen designing noise screens, piling is usually the chosen foundation type. There are several approximating models that can be used to determine the required pile length; these depend on the soil conditions and wind loads. However, if the pile is placed near a slope, the calculations will be considerably more uncertain as the impact of a slope on the horizontal stability of the pile is difficult t

Landskapet Dalarna i södra centrala Sverige uppvisar en stor variation av kvartärgeologiska sediment och landformer, bildade från deglaciationen i tidig Holocen och senare. Ett speciellt deglaciationsmönster, tillsammans med unika hydrologiska förhållanden, har lämnat utrymme för spekulationer över paleo-miljömässiga förhållandena under det tidiga Holocen. Siljanbassängen, belägen i det södra randThe Dalarna province in south-central Sweden shows a great variety of geological evidence from the Late Quaternary. A peculiar deglaciation pattern, along with unique hydrological conditions, has left a lot of space for speculations over the palaeoenvironmental conditions during the early Holocene. Lake Siljan is in the southern perimeter of the Siljan impact structure, the most prominent in Europ

Kvaliteten på dricksvatten kontrolleras av huvudmannen (ofta en kommunal organisation) som också är ansvariga för underhåll på ledningsnätet. En typ av underhållsmetod för dricksvattenlendingar är luft- och vattenspolning. Pollex AB är ett företag som bl.a. utför luft- och vattenspolning. De bedömer effekten av arbetet genom att med mätglas observera förändring i partikelinnehåll och missfärgning The quality of drinking water is controlled by the water organisation/company that delivers water to consumers, the organisation is also responsible of the maintenance of the drinking water distribution system. One method of maintenance is called air scouring. Pollex AB is a company utilizing, among other methods, air scouring. The staff assess the effect of the work by using a transparent plastic

Accurate production scheduling is an essential element to obtain high performing manufacturing facilities. By optimally allocating the available resources in a factory, improved equipment utilization, and hence production efficiency, can be reached. It is important that the planning considers factors that potentially restrict the available capacity, to access an uninterrupted process flow in the m

For years researchers have studied retention and turnover, yet there is still no single solution for the problem of balancing both these concepts in organizations. Turnover is defined as the rupture of ties between an employee and his/her organization, whilst retention is defined as the option of the employee to stay in the organization while not looking out for other job alternatives. These two c

The main objective of this research study is to investigate how today’s leaders experience remote leadership, thus the following research question is examined: How does a leader make sense of remote leadership? The concept of remote leadership is investigated from a leader perspective using a qualitative method, interviewing 11 remote leaders in the private sector. The following categories have em

With the advent of autonomous vehicles (AV) comes a plethora of new parameters to take into consideration in automotive design. Over the years, traffic signals and rules have developed in symbiosis, and are clear and easy to understand when the communication is between drivers. It is less clear between driver and pedestrian, especially when a pedestrian intends to cross the street. A non-verbal ag

Methodology: A literature study was conducted in which secondary data from pre

Korslimmat trä, eller KL-trä, har gett nya möjligheter för storskaligt byggande av träkonstruktioner. Träets låga egenvikt kan dock resultera i ökad risk för vibrationer som upplevs obehagliga och mentalt påfrestande. Därför behövs bättre förståelse för det dynamiska beteendet av KL-trä för framtida användning. Datorsimuleringar för bjälklag av KL-trä kan dock vara tidskrävande och ibland försvåraThe deregulation of timber for use in large scale constructions has seen the addition of new innovative timber-based products to a category of products referred to as engineered wood products. A now well established addition to these products is cross laminated timber, or CLT for short. CLT products use a form of orthogonal layering, where several parallel wooden boards are arranged in a number of

Introduction: Dental caries among preschool children is a global problem, a burden on children’s well-being, and an economic burden on healthcare systems. In Sweden, preschool children with an immigrant background have a higher prevalence of caries. Extensive treatment need and long-standing poor oral health may require dental treatment within hospital care. This study aimed to investigate whether

Anammox-processen erbjuder en hållbar och energieffektiv metod för biologisk kväve-avskiljning inom avloppsrening. Men bakterierna som utför arbetet kväver en källa till nitrit, och en möjlig lösning på detta är att kombinera metoden med partiell denitrifikation. Kan ett samarbete mellan dessa olika grupper av mikroorganismer upprättas, och vilken påverkan har typen av kolkälla som används i proceIn traditional wastewater treatment, nitrogen is removed through the biological process combination of nitrification and denitrification. Although it is a well-established method, the need for aeration and possible addition of an external carbon source results in it being an energy-negative and costly process, thus making alternative methods for nitrogen removal compelling to examine. Anaerobic am
