A search is preseritecl for same-sign top-quark production and down-type heavy quarks of charge -1/3 in events with two isolated leptons (c or mu) that have the same electric charge, at least two jets and large missing transverse momentum. The data are selected from pp collisions at root s = 7 TeV recorded by the ATLAS detector and correspond to an integrated luminosity of 1.04 fb(-1). The observe

An easy-to-use sample environment reaction cell for X-ray based in situ studies of powders and small structured samples, e.g., powder, pellet, and monolith catalysts, is described. The design of the cell allows for flexible use of appropriate X-ray transparent windows, shielding the sample from ambient conditions, such that incident X-ray energies as low as 3 keV can be used. Thus, in situ X-ray a

Lignocellulosic biomass can be utilized to produce ethanol, a promising alternative energy source produced through fermentation of sugars. However, in order to achieve high sugar and ethanol yields, the lignocellulosic material must be pretreated before the enzymatic hydrolysis and fermentation. Dilute acid pretreatment, using SO2, is one of the most promising methods of pretreatment for softwood

The objective of the present study was to develop an experimental model suitable for studying the effects of a nonhemorrhagic soft tissue trauma on plasma volume (PV) and microvascular permeability. Anesthetized Sprague-Dawley rats were exposed to a sham procedure or a laparotomy followed by a standardized trauma to the abdominal rectus muscle. We evaluated the effects of trauma on transcapillary

The classical system for presentation of the 12-lead electrocardiogram (ECG) reflects the electrical activity of the heart as viewed in the transverse plane by 6 leads with a single anatomically ordered sequence, V1-V6; but in the frontal plane by 6 leads with dual sequences, I, II, and III, and aVR, aVL, and aVF. However, there is also a single anatomically ordered sequence of leads, called the C

A methodology for evaluation of natural draft cooling tower (CT) performance and its application is presented. The study establishes the connection between CT performance and power output. It can estimate a change in a CT’s efficiency as well as an increase in power output as a function of cooling water temperature and load to the plant. The methodology consists of three subparts, i.e. Cooling Tow

Background Trials of imatinib have provided evidence of activity in adults with Philadelphia-chromosome-positive acute lymphoblastic leukaemia (ALL), but the drug's role when given with multidrug chemotherapy to children is unknown. This study assesses the safety and efficacy of oral imatinib in association with a Berlin-Frankfurt-Munster intensive chemotherapy regimen and allo geneic stem-cell tr

Robot-assisted surgery is a promising technical innovation. Given the similarities between laparoscopic and robot-assisted surgery it is unlikely that randomized controlled trials would be conducted to disclose any differences between these two technical instruments. Thus, skepticism remains due to lack of any definitive conclusions in the literature.

III-V-based nanowires usually exhibit random mixtures of wurtzite (WZ) and zinc blende (ZB) crystal structure, and pure crystal phase wires represent the exception rather than the rule. In this work, the effective group V hydride flow was the only growth parameter which was changed during MOVPE growth to promote transitions from WZ to ZB and from ZB to WZ. Our technique works in the same way for a

Aim: To describe the use of mobility devices among people ageing with spinal cord injury (SCI), with a specific focus on use of powered mobility devices (PMD) and housing accessibility. Method: Data on the use of walking aids (cane, crutch/es or rollator), manual wheelchair and powered wheelchair/scooter were utilized. To describe functional limitations, environmental barriers and the magnitude of

Dementia is the most common cause of functional decline among elderly people and is associated with high costs of national healthcare in European countries. With increasing functional and cognitive decline, it is likely that many people suffering from dementia will receive institutional care in their lifetime. To delay entry to institutional care, many European countries invest in home and communi

Accessible design enables participation in the digital society for everyone. However, cognitive accessibility is not well established within the field of web design. The International Classification of Functioning, Disability and Health (ICF) provides a descriptive framework that relates health conditions to functioning and participation. ICF Core Sets are purposefully tailored shortlists of ICF c

To predict major pressure losses from pumping shear thinning liquid foods and beverage, rheometer-measured flow behaviour (n) and flow consistency (K) indices are needed. These are always obtained with some measurement uncertainty. This contribution develops a tool that allows for quantitatively estimating how a given measurement uncertainty in the rheological parameters translate to predictio

Background: Rare disease clinical trials are notorious for complexities that frequently result in study-start delays. However, there is limited knowledge about how participants and researchers perceive these delays and what factors shape their experiences. A clinical trial in the rare, progressive disorder Pantothenate Kinase-Associated Neurodegeneration—the PKAN trial—encountered an unexpected de

STUDY QUESTION What are the perspectives of oocyte and sperm donors 14-17 years post-donation on the release of their identity and potential contact with donor-conceived offspring (DCO)? SUMMARY ANSWER Most oocyte and sperm donors wanted to be notified about future releases of their identity and were positive towards contact with DCO, but more than half expressed a need for support in relation to

Vacuum membrane distillation is a promising technology for seawater desalination, as it enables high recovery ratios, with reasonable thermal and minimal electric consumption. Ceramic membranes can offer notable advantages over polymeric membranes, mainly due to their robust thermal and mechanical stability, yet they have limited representation in the literature. Accordingly, this work investigate

Climate change is one of the major drivers of biodiversity loss. Among vertebrates, amphibians are one of the more sensitive groups to climate change due to their unique ecology, habitat requirements, narrow thermal tolerance and relatively limited dispersal abilities. We projected the influence of climate change on an endemic toad, Malabar Tree Toad (Pedostibes tuberculosus; hereafter MTT) from t

Facilitated CO stripping: Partial metallization of TiO2 nanoparticles (NPs) by electroreduction in the molten, eutectic mixture of CaCl2 and NaCl at 600 °C produces nano- and submicro-sized Ti2O and CaδTiOx (perovskites, x/× δ 2) that can significantly promote the catalytic activity of Pt NPs towards the oxidation of CO and CH3OH in acidic solutions

The governance of agricultural resources, particularly seeds, has long been a site of contestation between corporate-aligned institutions promoting proprietary seed laws and smallholder farmers, civil society organisations, and food sovereignty advocates defending traditional seed systems and local control. In Ghana, the introduction and eventual passage of the Plant Variety Protection Act of 2020
