The main objective of this paper is to demonstrate how greenhouse gas (GHG) emissions can be quantified during the evaluation of control strategies in wastewater treatment plants (WWTP). A modified version of the IWA Benchmark Simulation Model No 2 (BSM2G) is hereby used as a simulation case study. Thus, the traditional effluent quality index (EQI), operational cost index (OCI) and time in violati

In this paper we present some ideas for knowledge representation formalism suitable for rational agents which learn how to choose the best conditional, partial plan in any given situation. In our architecture, the agent uses an incomplete symbolic inference engine, employing Active Logic, to reason about consequences of performing actions — including information-providing ones. It utilises a simpl

Potentiation of spinal nociceptive transmission by synaptic delivery of AMPA receptors, via an NMDA receptor- and Ca(2+)/calmodulin-dependent protein kinase II (CaMKII)-dependent pathway, has been proposed to underlie certain forms of hyperalgesia, the enhanced pain sensitivity that may accompany inflammation or tissue injury. However, the specific synaptic populations that may be subject to such

This study from the Swedish Hip Arthroplasty Register (SHAR) compares cemented (Thompson(®), Exeter Trauma Stem (ETS)(®)) and uncemented (Austin-Moore(®)) monoblock hemiarthroplasties (n=1116 and 616, respectively) with modular ones (n=18,659). Austin-Moore(®) prostheses lead to more re-operations (6.7%) compared to modular implants (3.5%) and Thompson(®)/ETS(®) (2.4%). A Cox regression analysis,

B cell homeostasis is regulated by multiple signaling processes, including nuclear factor-kappaB (NF-kappaB), BAFF-, and B cell receptor signaling. Conditional disruption of genes involved in these pathways has shed light on the mechanisms governing signaling from the cell surface to the nucleus. We describe a novel mouse strain that expresses solely and excessively a naturally occurring splice va

Wnt-5a is a non-transforming Wnt protein that is implicated in cell-polarity, adhesion and motility. We have previously shown that low expression of Wnt-5a is a predictor of shorter disease-free survival in human breast cancer. Here, we investigated whether ss-catenin/E-cadherin mediated cell-cell adhesion was affected by loss of Wnt-5a in breast carcinomas, thereby promoting a metastatic behavior

AIM: The adiponutrin gene family consists of five genes (PNPLA1-5) coding for proteins with both lipolytic and lipogenic properties. PNPLA3 has previously been associated with adult obesity. Here we investigated the possible association between genetic variants in these genes and childhood and adolescent obesity. METHODS/RESULTS: Polymorphisms in the five genes of the adiponutrin gene family were

Retinal angiogenesis is tightly regulated to meet oxygenation and nutritional requirements. In diseases such as proliferative diabetic retinopathy and neovascular age-related macular degeneration, uncontrolled angiogenesis can lead to blindness. Our goal is to better understand the molecular processes controlling retinal angiogenesis and discover novel drugs that inhibit retinal neovascularisation

OBJECTIVE: To compare nerve conduction study results, before and after surgical carpal tunnel release, in diabetic and non-diabetic patients. METHODS: In a prospective study (2004-2007), we included 35 consecutive diabetic patients with carpal tunnel syndrome (CTS), who were age and gender matched with 31 non-diabetic patients having idiopathic CTS. Preoperatively, and at the 1year follow-up, nerv

Popular Abstract in Swedish Hjälpsystem i tunga fordon (bussar)As more and more focus is put on the environmental questions and the request for cleaner transportation the demand on the vehicles increases. Especially the environmental request of the public transportation that is visible to the public and operates in the centre of the city. The demand on the buses used for public transportation will increase. The whole bus must be optimised, usually only the pr

The problem addressed in this thesis is how to account for environmental aspects when purchasing freight transports. This problem is addressed from a transport purchasing perspective. The result of the research is a model for how transport purchasers can incorporate environmental aspects when purchasing freight transports. This mode! is built on two tools and a work process. The first too! is a st

Background: Ulnar nerve entrapment at the elbow (UNE) is overrepresented in patients with diabetes, but the outcome of surgery is unknown. We aimed to evaluate patient-reported outcome in patients with and without diabetes, and to assess potential sex differences and compare surgical treatment methods. Methods: Data on patients operated for UNE (2010-2016, n = 1354) from the Swedish National Regis

Introduction: Occupational health and safety management systems are widely used as a systematic approach to managing occupational health and safety. However, sometimes they are restrictive and underspecified to deal with dynamic workplace demands. Rasmussen used a model of boundaries to conceptualize this dynamic model of safety, where the space of possibilities lay within 3 boundaries and workers

Purpose: The purpose of the paper is to build on current discussions about the need for and role of guidance in learning and teaching, as well as to theoretically develop its specifics to further advance our scholarly understanding of how to structure and enhance entrepreneurship education. Design/methodology/approach: The paper takes a synthesizing conceptual approach, built on developmental psyc
