I mogna industrier prioriteras ofta verkningsgrad och processen snarare än själva produkten. Detta innebär att dessa industrier anpassar sig långsamt när de externa förhållandena skiftar. Exempel på sådan industri är Sveriges köttindustri. Denna präglas av stor klimatpåverkan, även stora mängder matsvinn. Nya teknologier undersökes i nuläget för att skärpa detta svinn; exempel på sådan teknologi äThe competitive landscape mature industries find themselves in tends to make them enforce practices that ruthlessly focus on efficiency and process. This narrow focus makes them slow to adapt to changes in the external environment in which they operate. One such case is the Swedish meat industry. Like many industries, there are downsides involved with meat production and for meat a significant one

Karst är landskap och karakteristika som är viktiga både ur hydrologisk och geologisk synpunkt och som är utvecklade genom vattnets vittring av oftast karbonathaltiga stenar. Denna uppsats kartlägger världens karstområden, beskriver egenskaper av karst och karsthydrologi och strävar efter att definiera problem och möjligheter med vattenhantering i karstlandskap. Akvifärer i karst skiljer sig i månSummary: Water is, and will in the near future be even more, a key issue for the global development, and for issues concerning equal rigts for all mankind. Water is a necessity and a scarce resource in great parts of the world and it therefore exists a great need for development and management of the world’s waters. With fresh waters being increasingly accentuated for their importance in global de

The final purpose of this project is to create a platform that leads to the improvement of the braking feeling by the users of heavy vehicles. The complexity of the problem lays on the different constraints: geometrical and functional, and as well on the interaction with a human operator. The task is to design a new electronic brake pedal, with the possibility to change the relationship between fo

Political analyses of the reform period China are plentiful, and for each analysis, there seems to be another version of a “China Model” or “Beijing Consensus” for economic and social development. This paper argues that these vague conceptualizations need to be rooted in empirical observations; they need to be products of induction rather than deductive processes that reiterate the preconceptions

The aim of this paper is to provide guidance in selecting phosphorus recovery options within the municipal wastewater treatment sector regarding developing countries. This critical review includes a brief contextualization of the resource-oriented sanitation paradigm, the discussion of processes for phosphorus recovery based on methods at full-scale, pilot-scale and laboratory-scale, and a concise

The use of gluten-free products is increasing since an increasing number of people (1-2 %) are suffering from Celiac disease and thereby need a gluten-free diet. Gluten-free bread tends to have shorter shelf life and quality compared with white wheat bread. In this study, 3 % (flour basis) of pre-gelatinized oat and barley flour as well as an emulsifier were added to a gluten-free mix to increase

Water and energy are essential resources for all people. However, despite the availability of sufficient water and energy resources, men and women continue to be subject to unequal rights to both water and energy in terms of access, allocation, gathering, and quality of resources. Socioeconomic parameters, which include gender, income, and location, are determinant factors of water and cooking ene

Insects have evolved diverse and remarkable strategies for navigating in various ecologies all over the world. In particular, central place foragers, such as bees and ants, have become renowned for their fascinating navigational capabilities. At the heart of insect navigation lies a brain area known as the central complex (CX). Functionally, the CX integrates world-centric sensory information with

A dyadic algorithm for diagonalizing an arbitrary positive definite band matrix, referred to as a band Gramian, is obtained to efficiently orthogonalize the B-splines. The algorithm can be also used as a fast inversion method for a band Gramian characterized by remarkable sparsity of the diagonalizing matrix. There are two versions of the algorithm: the first one is more efficient and is applicabl

Estimating crop evapotranspiration (ETa) is an important requirement for a rational assessment and management of water resources. The various remote sensing products allow the determination of crops’ biophysical variables integrated in the evaluation of ETa by using surface energy balance (SEB) models. This study compares ETa estimated by the simplified surface energy balance index (S-SEBI) using

The study of economic development in African countries is facing a basic problem of lack of reliable data and statistics. These problems of economic data are best addressed under three main categories: design, capacity, and politics. The focus is on gross domestic product (GDP), but the relevance goes beyond GDP statistics because the aggregate of GDP requires economic data on all sectors of the e

The information of water level variations in lakes and reservoirs is essential for many applications such as water resources management. The conventional in-situ measurements of water levels based on gauge station are often rarely available or difficult to be shared to the public especially for lakes in the developing countries and transboundary basins. Satellite altimetry provides an alternative

Packaging developers in the food industry must consider several, sometimes conflicting, environmental requirements on packaging along with an already complex combination of marketing, logistics and production requirements. Existing methods for the environmental evaluation of packaging either focus on a limited amount of environmental packaging criteria (such as recyclability or renewable content)

Objectives: Lung squamous cell carcinoma (LUSC) is associated with a poor prognosis and a lack of specific treatment options. The dysregulation of activin A (ActA) has been reported in various malignancies. Herein, we investigated the diagnostic and prognostic significance of ActA in LUSC. Materials and methods: ActA concentrations were measured using ELISA in plasma samples of 128 LUSC patients (

Health-related quality of life (HRQL) is a multidimensional concept which captures the individual’s perception of treatment burden. Evaluating HRQL during treatment for childhood cancer provides insight into the burden of the treatment from the child’s and/or parent’s perspective.In this review, we aimed to describe Patient-Reported Outcome Measures (PROMs) used to measure HRQL during treatment, d

Carbon materials with unique sp2-hybridization are extensively researched for catalytic applications due to their excellent conductivity and tunable physicochemical properties. However, the development of economic approaches to tailoring carbon materials into desired morphologies remains a challenge. Herein, a convenient “bottom-up” strategy by pyrolysis of graphitic carbon nitride (g-C3N4) (or ot

Tactile feedback plays a vital role in inducing ownership and improving motor control of prosthetic hands. However, commercially available prosthetic hands typically do not provide tactile feedback and because of that the prosthetic user must rely on visual input to adjust the grip. The classical rubber hand illusion (RHI) where a brush is stroking the rubber hand, and the user's hidden hand synch

BACKGROUND: Atypical hemolytic uremic syndrome (aHUS) can be associated with mutations, deletions, or hybrid genes in factor H-related (FHR) proteins.METHODS: A child with aHUS was investigated. Genetics was assessed by Sanger and next generation sequencing. Serum FHR5 was evaluated by immunoblotting, ELISA, and by induction of rabbit red blood cell hemolysis in the presence/absence of recombinant

Nine Ce ii lines have been identified and characterized within the spectral window observed by the Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey (between λ1.51 and 1.69 μm). At solar metallicities, cerium is an element that is produced predominantly as a result of the slow capture of neutrons (the s-process) during asymptotic giant branch stellar evolution. The Ce ii lines
