Nonparametric efficiency analysis has become a widely applied technique to support industrial benchmarking as well as a variety of incentive-based regulation policies. In practice such exercises are often plagued by incomplete knowledge about the correct specifications of inputs and outputs.

Background: Incisional hernia is one of the most common complications after laparotomy. The aim of this retrospective study was to investigate incidence, location and risk factors for incisional hernia after open resection for colorectal liver metastases including the use of perioperative chemotherapy and targeted therapy evaluated by computed tomography. Methods: Patients operated for colorectal
An experiment to investigate the dispersal and supposed reattack by parent spruce bark beetles, Ips typographus (L.), was performed. More than 20,000 parent beetles were marked with fluorescent powder and immediately released from platforms when they reemerged from trees attacked during the spring swarming. Thirty‐eight marked and over 8000 unmarked beetles were trapped on sticky traps covering 21
Inside-out submitochondrial particles (IO-SMP) were isolated and purified from potato (Solanum tuberosum L. cv.) tubers. When these IO-SMP were incubated with [γ32P]ATP more then 20 proteins became labelled as a result of phosphorylation. The 32P incorporation was stimulated by the oxidizing reagent ferricyanide. Except for a 17 kDa protein which was phosphorylated only in the absence of divalent
Purpose– The purpose of this paper is to determine the optimal office lighting use with different types of lighting controls to achieve energy savings and provide visual comfort for individuals.Design/methodology/approach– A case study and field measurements were carried out in 18 single-occupancy offices in Sweden where six different lighting controls were investigated. Occupancy and daylight hou
Background: The use of methylisothiazolinone (MI) as a preservative in cosmetic products caused an alarming increase in MI contact allergy across Europe in the 2010s. This was followed by regulations of use with a total ban on leave-on (implemented in 2017) and reduced use concentrations in rinse-off cosmetics (2018). Objective: To follow-up on the prevalence of contact allergy to MI and the relat
Hydropower is one of the renewable energy sources having the highest conversion efficiency than other renewable energy sources. The hydro turbine is considered as the main component of a hydropower plant and operation and maintenance of various components are the critical issues for optimal energy generation. Under the present paper, a comprehensive literature review on the operation and maintenan
This study investigates the relationship between changes in the frequency of dwell time delays and passenger flow characteristics and the frequency of railway service during the COVID-19 pandemic. To do so we make use of automatic passenger count data from commuter trains in Southern Sweden. Our findings show that the frequency of dwell time delays decreased under COVID-19 conditions compared to t
Lately there has been an increasing focus on saving peak power in heating systems as a way to lower the environmental load past just saving energy. At the same time, active cooling is becoming increasingly interesting. Sweden has more and more cooling systems with an increase in cooling also in residential buildings. The cooling power is much more expensive than the heating power. Therefore, there
The idiom ‘for someone’s sake’ plays a central role in recent attempts to understand the distinction between impersonal values and personal values—e.g. between what is valuable or good, period, and what is valuable for or good for someone. In the first section three historical approaches to this distinction are outlined. Section 2 presents a modified fitting-attitude (FA) analysis of final ‘value-
The cholesterol-lowering effects of oats have led to an increasing interest in them on the food market. Liquid oats has emerged as a new way of consuming oats and has become a commercial product. To produce liquid oats, steam-heated dehulled oat groats are subjected to flaking, wet-milling, enzyme hydrolysis, decanting, formulation, and ultra-high-temperature (UHT) treatment, the resulting beverag
Huntington disease is an inherited, progressive, incurable neurodegenerative disorder that primarily affects cells in the brain. Although the genetic basis for this condition has been known for nearly 30 years, how this causes disease is still unresolved. Of late there has been increasing evidence suggesting that dysfunction in macroautophagic/autophagic pathways may contribute to cellular dysfunc
The use of a learning management/assessment system has become common in higher education during the past 20 years. However, such systems are frequently not grounded in approaches to support longitudinal educational needs, such as promoting professional development. One reason may be that digital support is designed to assist with isolated tasks e.g. running MCQ tests, and therefore is not develope
This paper reports the observation of top-quark pair production in proton-lead collisions in the ATLAS experiment at the Large Hadron Collider. The measurement is performed using 165 nb−1 of p+Pb data collected at sNN = 8.16 TeV in 2016. Events are categorised in two analysis channels, consisting of either events with exactly one lepton (electron or muon) and at least four jets, or events with two
