Improved Prognosis and Low Failure Rate with Anticoagulation as First-Line Therapy in Mesenteric Venous Thrombosis

Background Monotherapy with anticoagulation has been considered as first-line therapy in patients with mesenteric venous thrombosis (MVT). The aim of this study was to evaluate outcome, prognostic factors, and failure rate of anticoagulation as monotherapy, and to identify when bowel resection was needed.Methods Retrospective study of consecutive patients with MVT diagnosed between 2000 and 2015.RBACKGROUND: Monotherapy with anticoagulation has been considered as first-line therapy in patients with mesenteric venous thrombosis (MVT).

Progress and challenges to the global waste management system

Rapid economic growth, urbanization and increasing population have caused (materially intensive) resource consumption to increase, and consequently the release of large amounts of waste to the environment. From a global perspective, current waste and resource management lacks a holistic approach covering the whole chain of product design, raw material extraction, production, consumption, recycling

Enhancing Reuse and Resource Recovery of Electrical and Electronic Equipment with Reverse Logistics to Meet Carbon Reduction Targets

Technological advances, with increasing numbers of products containing complex electronic circuitry, have resulted in e-waste becoming the fastest-growing global waste stream. High levels of embodied carbon in these products ensure that, to meet emissions reduction targets proposed by the United Nations Paris Agreement, tackling e-waste requires strategies to address climate change United Nations

Consumer Perspectives on longevity and Reliability : A National Study of Purchasing Factors Across Eighteen Product Categories

Increasing global demand for durable goods prevents the decoupling of economic growth from natural resource use required to achieve sustainable consumption and production. Presently, most consumers in the United Kingdom (UK) exhibit a strong preference for purchasing new durable goods. Therefore, short-to-medium term strategies that seek to engender sustainable consumption of durable goods should

Towards a Sustainable Business Model for Plastic Shopping Bag Management in Sweden

From an environmental perspective, a separate collection and recycling system for post-consumer discards could contribute to improved environmental protection as well as economic benefits. This paper investigates the environmental potential of a business model proposed in Sweden in order to improve the utilization of plastic shopping bags. The business model aims to reduce the consumption of plast

Identifying ways of closing the metal flow loop in the global mobile phone product system : A system dynamics modeling approach

In the past few decades, e-waste has emerged as one of the fastest growing and increasingly complex waste flows world-wide. Within e-waste, the life cycle of the mobile phone product system is particularly important because of: (1) the increasing quantities of mobile phones in this waste flow; and (2) the sustainability challenges associated with the emerging economies of reuse, refurbishment, and

Unintended Environmental Consequences of Improvement Actions : A Qualitative Analysis of Systems' Structure and Behavior

We qualitatively analysed how and why environmental improvement actions often lead to unintended environmental consequences. Different theories are integrated to delineate the underlying system structure causing this system behavior. Causal loop diagram technique is utilized to explore and visualize: how incremental improvements in material and energy efficiency can unintendedly cause consumption

Towards Addressing Unintended Environmental Consequences : A Planning Framework

Efforts to decouple environmental impacts and resource consumption have been confounded by interactions and feedback between technical-economic, environmental and social aspects not considered prior to implementing improvement actions. This paper presents a planning framework that connects material flows and the socio-economic drivers that result in changes in these flows, in order to reduce confl

Some pervasive challenges to sustainability by design of electronic products - A conceptual discussion

Sustainability should encompass responsibility for unintended environmental consequences of modern developments. This study examined some pervasive challenges to sustainability by design of electronic products, namely: (i) product and consumption redundancies; (i) embodied environmental and social impacts occurring distant in time and space from the point of consumption; and (iii) production and c

Resource recovery from post-consumer waste : important lessons for the upcoming circular economy

A circular economy has been proposed as a sustainable alternative to our current linear economic system, mainly by recirculating material resources for new product development. To understand resource recirculation in practice, this paper analyses over 50 examples of products developed from discarded materials, categorising them into the recovery routes described in the circular economy literature.

Evaluating low-carbon city initiatives from the DPSIR framework perspective

Current low-carbon city initiatives were evaluated using the DPSIR (Driving forces-Pressures-State-Impacts-Responses) causal-effect framework for investigating interactions between environmental issues and human activities. For effective management towards achieving a low-carbon city, integrating the pressure-based, driver-oriented DPSIR approach could help decision makers examine whether greenhou

Towards a Sustainable Resource Management : a broader systems approach to product design and waste management

Rapid economic growth, urbanisation and increasing population have caused (materially intensive) resource consumption to increase, and consequently the release of large amounts of waste to the environment. Numerous technological and operational approaches to resource management have been introduced throughout the system of production, consumption and waste management. This thesis concludes that th

Beyond Waste Management

Current physical resource management (PRM) was investigated in a global perspective in this thesis, to gain a deeper understanding of its implications in a sustainability perspective. In particular, the main challenges to the current PRM system and the kinds of systemic changes needed for sustainable PRM were examined. In five separate studies, different theoretical and practical challenges to cur

The Socio-Economic Embeddedness of the Circular Economy: An Integrative Framework

Global economies have been characterised by a large dependency of material inflows from natural stocks, an exponential growth of material stock-in-use in the built environment, and the extensive disposal of waste material outflows to anthropogenic sinks. In this context, the concept of the circular economy has emerged, promising to circulate the stock-in-use of materials and transforming output wa

De obesuttnas arkeologi och kulturarv (ca. 1700-1900)

This paper aims to present a recently started project about the heritage of subaltern people in Sweden. In the paper we focus on the parts of the project that concerns the rural history of the 18th and 19th centuries, especially crofters. The background to the project is the introduction of major changes in the Swedish Historic Environments Act in 2014. A radical novelty is that remains of human aThis paper aims to present a recently started project about the heritage of subaltern people in Sweden.

A non-linear model of hydrogen production by Caldicellulosiruptor saccharolyticus for diauxic-like consumption of lignocellulosic sugar mixtures

Background: Caldicellulosiruptor saccharolyticus is an attractive hydrogen producer suitable for growth on various lignocellulosic substrates. The aim of this study was to quantify uptake of pentose and hexose monosaccharides in anindustrial substrate and to present a kinetic growth model of C. saccharolyticus that includes sugar uptake on defined and industrial media. The model is based on Monod
