The demand for cheaper and more efficient solar cells is high. One way to decrease cost of material, while maintaining a high degree of efficiency, is to take advantage of nanomaterials. A thin film containing pn-junction nanowires can convert light with an efficiency comparable to traditional planar cells, while using a fraction of the material, and thus reduce costs.

Today, many cities around the world are looking for means to reduce their consumption-originated emissions and in this way improve their sustainability. Consequently, local governments are becoming increasingly interested in the potential of the ‘sharing economy’ (SE). By enabling the consumption of resources and services through sharing as opposed to purchasing goods for ownership, urban sharing
Aim: The first Swedish National Guidelines for Ovarian Cancer (NGOC) were published in 2012. We aimed to evaluate surgical outcomes and survival in patients with stage IIIC-IV disease, before and after the NGOC implementation. Method: Women with primary epithelial ovarian cancer, FIGO stage IIIC–IV, registered in the Swedish Quality Registry for Gynecologic Cancer 2008–2011 and 2013–2016 were incl
Background: Avoidable mortality is considered as a potential indicator of the influences of public health policies and healthcare quality on population health. This study aimed to examine the trend in avoidable mortality and its influence on rising life expectancy (LE) and declining gender gap in LE (GGLE) in Sweden. Methods: We extracted data on causes of death by age, sex, and year from nationa
This paper is a comprehensive review of in-cycle closed-loop combustion controllers to achieve higher indicated efficiencies. Closed-loop combustion control reduces the effect of external disturbances and system uncertainties, which permit tighter safety margins and robust operation with a reduced calibration effort. The paper combines different components of previous investigations by the authors
Introduction: The aim of the study is to compare the effect of cervical length measured with transvaginal ultrasound in the second trimester on the risk of spontaneous preterm delivery (PTD) between different risk groups of asymptomatic women with a singleton pregnancy. Material and methods: This is a pre-planned exploratory analysis of the CERVIX study, a prospective blinded multicenter diagnosti
Heating the 50-electron cluster [Fe3(CO)9 (μ3-Te)2] (1) with the diphosphines Ph2P-R-PPh2 [R = -CH2CH2- (dppe), Z-CH=CH- (dppv), 1,2-C6H4 (dppb), -CH2CH2CH2- (dpp), ferrocenyl (dppf), naphthalenyl (dppbn)] in benzene affords the 52-electron diphosphine-containing tellurium-capped triiron clusters [Fe3(CO)8 (μ3-Te)2 (κ2-diphosphine)] (diphosphine = dppe, dppv, dppb, dpp, dppf, dppnd) (2–7) in moder
Background: Early initiation of breastfeeding (EIBF) lowers the risk for all-cause mortality in babies, including those with low birth weight. However, rates of neonatal mortality and delayed initiation of breastfeeding remain high in most low- and middle-income countries. This study aimed to assess the trends and factors associated with EIBF in Namibia from 2000 to 2013. Methods: An analysis of E
The alternating between dry and wet seasons and the consecutive microbial responses to soil water content in semiarid ecosystems has significant consequences on nitrogen exchanges with the atmosphere. Three field campaigns were carried out in a semi arid sahelian rangeland in Dahra (Ferlo, Senegal), two at the beginning of the wet season in July 2012 and July 2013, and the third one in November 20
Summary: In community dwelling, 75-year-old women followed 10 years, a frailty index was created at each of three visits. Frailty score increased by ~ 6–7% annually. A higher frailty score was equivalent to being 5–10 years chronologically older. Frailty was associated with low bone density and higher risk of dying. Introduction: To understand the distribution of frailty among a population-based s
Background: Current EU directives demand increased use of renewable fuels in the transportation sector but restrict governmental support for production of biofuels produced from crops. The use of intercropped lucerne and wheat may comply with the directives. In the current study, the combination of ensiled lucerne (Medicago sativa L.) and wheat straw as substrate for hydrogen and methane productio
Background: High-circulating level of parathyroid hormone (PTH) is associated with elevated mortality in dialysis patients. The Japanese Society for Dialysis Therapy guideline suggests a lower PTH target than other international guidelines; thus, PTH control may differ in Japan compared with other regions, and be associated with mortality. Methods: We analyzed data from hemodialysis patients with
OBJECTIVES: To simplify the previously published Nottingham 12-year risk prediction model for knee osteoarthritis (OA) and examine whether it can be used to predict the 40-year risk of knee OA in young men.METHODS: We included 40 118 men aged 18 undergoing military conscription in Sweden 1969-70. Diagnostic OA codes were obtained from the Swedish National Patient Register 1987-2010. The original N
Klimatförändringarna kommer att påverka ekosystem och samhällen över hela världen. Det är ett problem som kräver drastiska och omedelbara förändringar av vårt sätt att leva och av våra samhällsstrukturer, och därmed politiskt engagemang av aldrig tidigare skådat slag. Under de senaste 30 åren, sedan bildandet av Förenta Nationernas ramkonvention om klimatförändringar (Klimatkonventionen; UNFCCC) åThe rise of climate change as an issue of global concern has rested on scientific representation and understanding of the causes and impacts of, and responses to climatic change. The Intergovernmental Panel on Climate Change (IPCC), in particular, has been central to how climate change has become known as a global political problem. This thesis aims to critically examine the production, negotiatio
Negative symptoms (avolition, anhedonia, asociality, blunted affect, and alogia) are among the most disabling features of schizophrenia spectrum disorders. In the absence of treatment consensus guidelines, this PRISMA-compliant meta-analysis (PROSPERO: CRD42024613967) evaluated efficacy and clinical significance of interventions targeting this dimension. Web of Science/PsycInfo databases were sear
Existing LLM-based approaches remain limited by simplistic task execution, restricted tool integration, and a lack of contextual reasoning when interacting with professional GIS software. This study investigates the efficacy of a multi-agent architecture designed to enhance geospatial task execution accuracy through collaboration, reasoning and tool-use. The architecture integrates Chain of Though
OBJECTIVES: Inhibitors of the glucagon-like peptide-1 (GLP-1)-degrading enzyme, dipeptidyl peptidase IV (DPPIV), are being explored in the treatment of diabetes. We examined the long-term influence of a selective, orally active inhibitor of DPPIV (NVP DPP728), in normal female C57BL/6J mice and such mice rendered glucose-intolerant and insulin-resistant by feeding a high-fat diet. DESIGN: In mice
Background Calcipotriol and betamethasone dipropionate are both widely used, effective treatments for psoriasis. Vitamin D analogues and topical corticosteroids have different mechanisms of action in the treatment of psoriasis. A new vehicle has been developed in order to contain both calcipotriol (50 micro g g-1) and betamethasone dipropionate (0.5 mg g-1) in an ointment form. By using calcipotri
