Hemoglobin (Hb)-based oxygen carriers (HBOCs) have been engineered to replace or augment the oxygen carrying capacity of erythrocytes. However, clinical results have generally been disappointing, in part due to the intrinsic oxidative toxicity of Hb. The most common HBOC starting material is adult human or bovine Hb. However, it has been suggested that fetal Hb may offer advantages due to decrease
The analysis of stable isotopes assisted in identifying that groundwater in the Punata alluvial fan is mainly recharged by heavy flash floods, and the recharge from rainfall is of less importance. In addition, the hydrochemical analysis identified the Pucara River as the main source of recharge. Other streams in the north and northwest of the fan do not seem to contribute to the recharge. The hydr
Stomatopods have an elaborate visual system served by a retina that is unique to this class of pancrustaceans. Its upper and lower eye hemispheres encode luminance and linear polarization while an equatorial band of photoreceptors termed the midband detects color, circularly polarized light and linear polarization in the ultraviolet. In common with many malacostracan crustaceans, stomatopods have
The extraction, supply, market price and recycling of the metals molybdenum and rhenium were modelled using an integrated system dynamics model. The resource estimates made here resulted in significantly larger estimates than earlier studies for molybdenum. Present molybdenum resources are about 75–80 million ton and about 7 million ton has been mined to date. The ultimately recoverable resources
This paper discusses the relevance of transient events of strong large-scale ocean evaporation (SLOE) for the deuteriumexcess of marine boundary layer vapor d using a theoretical framework that invokes the closure assumption. We argue that during SLOE events, d is essentially determined by the evaporation flux signature. Distinct high d during SLOE with global-mean values in the range of 12‰-23‰ d
The International Commission on Stratigraphy and the IUGS Executive Committee have recently approved a Global Standard Stratotype-section and Point (GSSP) defining the base of the second stage of the Furongian Series, Cambrian System. This stage is named the Jiangshanian Stage, after Jiangshan City, western Zhejiang Province, China, where the GSSP is located. The GSSP is exposed in a natural outcr
A proactive strategy to respond effectively to health impacts related to climate variability, particularly within vulnerable populations, is of vital importance. Such a strategy can be attained if health officials have a deep understanding of how climate variability affects human health and if the resources available for the health care sector are sufficient. This study assessed the perceptions an
This essay develops a theory for the explanation of the differences in success of Radical Right Populist Parties in Western Europe. In order to create a successful radical right populist movement and thus a successful radical right populist party, three elements are needed; ?demand?, ?supply? and ?mobilisation?. Because the creation of a radical right populist movement is different than the creat
Tourism is an industry with considerable environmental and social impacts; in order to stimulate reduction of these impacts, voluntary recognition schemes i.e. ecolabels and certification programmes have been introduced to motivate tourism businesses to improve their environmental performance, encourage more sustainable practices and patterns in this branch of economy, provide information to touri
Switching from fossil fuels to biofuels has already been proven to be a good business for some industries such as the pulp industry and the wood industry in general, but very limited experience exists about the profitability of this change in other industrial contexts. This thesis investigates the financial viability of a partial shift to a biomass based energy system for the structural ceramics
Natural resources hold a great potential for both economic and social development in developing countries. Many countries in Africa today are rich in natural resources but remain poor and underdeveloped. Policies and legislation within this sector need to provide a good framework in order for the natural resources to be properly managed. This report aims at discussing the difficulties in managing
Hydroelectric power is a controversial renewable energy. Adding more renewables to the energy mix is becoming more critical with the onslaught of climate change, while river health and water quality remain a highly pertinent environmental issue. Balancing the need for local renewable energy and environmental concerns is the topic of many cases. This thesis analyzes a case of conflict surrounding t
Neuronal endoplasmic reticulum (ER), continuous from soma to dendritic spines, undergoes rapid fragmentation in response to N-methyl-D-aspartate (NMDA) receptor stimulation in hippocampal slices and neuronal primary cultures. Here, we show that ER fragments in the mouse brain following cardiac arrest (CA) induced brain ischemia. The ER structure was assessed in vivo in cortical pyramidal neurons i
Background Few authors have investigated function and pain after surgical treatment of patients with bone metastases. In 1999 the Scandinavian Sarcoma Group (SSG) initiated the Skeletal Metastasis Registry as a multi-centric, prospective study to provide a scientific basis for recommendations of treatment. Patients and methods We have analyzed function and pain in 530 patients (mean age 65 yr) ope
Background: The activity level and subjective knee function after an anterior cruciate ligament (ACL) injury treated without reconstruction have not been well elucidated. Hypothesis: Patients with ACL injury can achieve good knee function and satisfactory long-term activity level when treated by early activity modification combined with rehabilitation. Study Design: Cohort study (prognosis); Level
In the Prince Charles Mountains (PCMs) the conformable Permian-Triassic (P-T) succession is characterised by an abrupt transition from coal-bearing to coal-lacking strata, which coincides with the demise of the Permian Glossopteris-dominated flora. About 32% of the typical Permian spores and pollen are registered for the last time in the uppermost coal. Throughout the earliest Triassic an addition

An inclusive search for anomalous production of two prompt, isolated muons with the same electric charge is presented. The search is performed in a data sample corresponding to 1.6 fb(-1) of integrated luminosity collected in 2011 at root s = 7 TeV with the ATLAS detector at the LHC. Muon pairs are selected by requiring two isolated muons of the same electric charge with p(T) > 20 GeV and vertical
