The influence of CO adsorption on the surface composition of cobalt/palladium alloys

Segregation induced by the adsorption of gas phase species can strongly influence the composition of bimetallic surfaces and can therefore play an important role in influencing heterogeneous catalytic reactions. The addition of palladium to cobalt catalysts has been shown to promote Fischer Tropsch catalysis. We investigate the adsorption of CO onto bimetallic CoPd surfaces on Pd{111} using a comb

Managing chemotherapy risks : Learning from medication errors and developing a national knowledge source for chemotherapy regimens

Grunderna i cancerbehandling är kirurgi, strålterapi och behandling med cancerläkemedel, ofta i kombination med varandra. Regimer med cancerläkemedel som definierar det eller de läkemedel som används, deras doser, hur ofta och hur länge de ska ges, har utvecklats och används för olika cancerdiagnoser. Flera professioner inom sjukvården är involverade i behandlingen: läkaren som ordinerar läkemedleThe basics in cancer treatment are surgery, radiation therapy, and treatment with cancer drugs, often combined. Chemotherapy regimens that define the drugs used, the dosage, the frequency and duration of drug administration, have been developed and used for different cancer diagnoses. Several healthcare professionals are involved in the treatment: the physician prescribing the drugs, the pharmacis

Unsettling the political : conceptualizing the political in feminist and LGBTI+ activism across Russia, the Scandinavian countries, and Turkey

This article aims to expand the ongoing theoretical debate on the broadened and context-specific notion of politics by offering an empirically nuanced conceptualization of political based on the study of feminist and LGBTI+ activism in Russia, Turkey, and the Scandinavian countries. We use a multi-scalar transnational approach to foreground connectivities across regions to challenge the nation-bou

Fast-neutron-induced fission cross section of Pu 242 measured at the neutron time-of-flight facility nELBE

The fast-neutron-induced fission cross section of Pu242 was measured at the neutron time-of-flight facility nELBE. A parallel-plate fission ionization chamber with novel, homogeneous, large-area Pu242 deposits on Si-wafer backings was used to determine this quantity relative to the IAEA neutron cross-section standard U235(n,f) in the energy range of 0.5 to 10 MeV. The number of target nuclei was d

A tale of clusters : No resolvable periodicity in the terrestrial impact cratering record

Rampino & Caldeira carry out a circular spectral analysis (CSA) of the terrestrial impact cratering record over the past 260 million years (Ma), and suggest a ∼26 Ma periodicity of impact events. For some of the impacts in that analysis, new accurate and high-precision ('robust'; 2SE < 2 per cent) 40Ar-39Ar ages have recently been published, resulting in significant age shifts. In a CSA of the

Grading Bias and Young Adult Mental Health

Various grading reforms and trends of more lenient grading have contributed to grade inflation in Sweden and other countries. Previous research shows that over-grading increases higher education enrolment, achievements and earnings, but no study has yet addressed the potential impact of grading bias on health. In this paper, we hypothesize that over-grading has a protective impact on mental health

Study of cosmic ray events with high muon multiplicity using the ALICE detector at the CERN Large Hadron Collider

ALICE is one of four large experiments at the CERN Large Hadron Collider near Geneva, specially designed to study particle production in ultra-relativistic heavy-ion collisions. Located 52 meters underground with 28 meters of overburden rock, it has also been used to detect muons produced by cosmic ray interactions in the upper atmosphere. In this paper, we present the multiplicity distribution of

Evidence of half-integer Shapiro steps originated from nonsinusoidal current phase relation in a short ballistic InAs nanowire Josephson junction

We report on half-integer Shapiro steps observed in a gate-tunable short ballistic InAs nanowire Josephson junction. We observed the Shapiro steps of the short ballistic InAs nanowire Josephson junction and found the half-integer steps in addition to the conventional integer steps. In this Josephson junction device the junction transmission can be varied with gate voltage. From measurements of the

Inclusive quarkonium production at forward rapidity in pp collisions at √s = 8 TeV

We report on the inclusive production cross sections of (Formula presented.) , (Formula presented.) , (Formula presented.) (1S), (Formula presented.) (2S) and (Formula presented.) (3S), measured at forward rapidity with the ALICE detector in (Formula presented.) collisions at a center-of-mass energy (Formula presented.) TeV. The analysis is based on data collected at the LHC and corresponds to an

The current practice of cytoreductive surgery and HIPEC for colorectal peritoneal metastases : Results of a worldwide web-based survey of the Peritoneal Surface Oncology Group International (PSOGI)

BACKGROUND: At present, selected patients with resectable colorectal peritoneal metastases (CRC-PM) are increasingly treated with a combination therapy of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). The aim of this study was to investigate the current worldwide practice.METHODS: HIPEC experts from 19 countries were invited through the Peritoneal Surface Oncol

Kulturarv till salu

Under våren 2022 ska den så kallade Everlöv-skatten säljas på offentlig auktion. Därför kommer skatten att splittras upp och föremålen därmed spridas vind för våg. Detta är mycket beklagansvärt ur vetenskaplig synvinkel, men även ur samhällets och allmänhetens perspektiv. Fornminnen och fornsaker, däribland naturligtvis vikingatida skattfynd, är vårt gemensamma kulturarv. Depåfyndet består av en s

Hyperthermic Intraperitoneal Chemotherapy in Ovarian Cancer

BACKGROUND: Treatment of newly diagnosed advanced-stage ovarian cancer typically involves cytoreductive surgery and systemic chemotherapy. We conducted a trial to investigate whether the addition of hyperthermic intraperitoneal chemotherapy (HIPEC) to interval cytoreductive surgery would improve outcomes among patients who were receiving neoadjuvant chemotherapy for stage III epithelial ovarian ca
