Lifetime measurements of excited states in 169,171,173Os : Persistence of anomalous B(E2) ratios in transitional rare earth nuclei in the presence of a decoupled i13/2 valence neutron

Lifetimes of low-lying excited states in the νi13/2+ bands of the neutron-deficient osmium isotopes 169,171,173Os have been measured for the first time using the recoil-distance Doppler shift and recoil-isomer tagging techniques. An unusually low value is observed for the ratio B(E2;21/2+→17/2+)/B(E2;17/2+→13/2+) in 169Os, similar to the “anomalously” low values of the ratio B(E2;41+→21+)/B(E2;21+

Evaluation of different coatings of the tibial tray in uncemented total knee arthroplasty. A randomized controlled trial with 5 years follow-up with RSA and DEXA

Background: Regenerex® is a porous titanium construct with a 3D interconnecting pore structure and biomechanical characteristics close to that of normal trabecular bone. This study aimed to compare the Regenerex (VR) to the non-interconnecting pore structure Porous Plasma Spray (VP) on tibial implants for total knee arthroplasty (TKA) at 5 years. Methods: We enrolled and randomized 61 patients (me

Thermal history of the southern Central Cordillera and its exhumation record in the Cenozoic deposits of the Upper Magdalena Valley, Colombia

The roughly 600 km long Central Cordillera of Colombia shows a varied tectonic, magmatic, and exhumation history, despite the reasonably homogenous appearance concerning topography, outcropping lithologies, and strike. Here we show with new geo-thermochronological data the thermal evolution of the southern Central Cordillera since the Early Jurassic. Extensive Jurassic magmatism is recorded by U–P

Dioxomolybdenum(VI) complexes of hydrazone phenolate ligands - syntheses and activities in catalytic oxidation reactions

The new cis-dioxomolybdenum (VI) complexes [MoO2(L2)(H2O)] (2) and [MoO2(L3)(H2O)] (3) containing the tridentate hydrazone-based ligands (H2L2 = N'-(3,5-di-tert-butyl-2-hydroxybenzylidene)-4-methylbenzohydrazide and H2L3 = N'-(2-hydroxybenzylidene)-2-(hydroxyimino)propanehydrazide) have been synthesized and characterized via IR, 1H and 13C NMR spectroscopy, mass spectrometry, and single crystal X-

Altered winter conditions impair plant development and yield in oilseed rape

The demand for agricultural products is expected to increase as a result of population growth, changed diets and demands for bioenergy. At the same time, agricultural yields in many regions are expected to be negatively impacted by climate change. Here we show, how altered winter conditions in combination with an extreme weather event impact reproductive development and yield of oilseed rape (Bras

Strängare straff har föga effekt när det gäller våld i nära relationer

Män som slår kvinnor är i regel återfallsbrottslingar, skriver forskaren Ardavan Khoshnood. Eftersom brotten begås i stundens hetta är straffens längd sällan avskräckande.Men who beat women are usually recidivists, writes researcher Ardavan Khoshnood. Because the crimes are committed in the heat of the moment, the length of the sentence is seldom dissuasive.

Orchestrating retail in small cities

The structural transformation of retail is challenging for many small cities. Rather than seeing the retailer as a sole player, this article considers retail in small cities to be shaped in a retail eco system consisting of many different actors besides retailers such as municipalities, landlords, business/city organisations, customers/citizens. The key contribution of the article is to provide ne

최근 노인의 재가서비스 이용 권리 확대 소식에 더하여 스웨덴 노인 주거복지서비스의 현황과 문제점, 그리고 이에 따른 정부의 대응 방안 등을 살펴본다. 최근 조사에 따르면 스웨덴 노인재가복지시스템은 인력 수급의 안정성과 전문성 부족, 인력 공급 부족, 지자체 간의 서비스 질 간극 확대, 재가서비스 이후 시설 서비스로의 이행 지체 등의 어려움을 안고 있다. 스웨덴 정부는 이와 같은 문제를 해결하기 위해 서비스 공급 인력을 양적으로 확대할 뿐 아니라 서비스 이행의 질을 개선하기 위해 집중하고 있다.

Sustainable architecture in context : STS and design thinking

There has been little emphasis in STS scholarship to date on the design of the built environment. This paper attempts to address this oversight by examining alternative design practices in the growing field of sustainable architecture. We propose a geohistorical framework that includes three design dispositions—context-bound, context-free, and context-rich—and illustrate each with a prominent sust

Pathways of urban nature : diversity in the greening of the twenty-first century city

Nature is a central component of the twenty-first-century city. Beyond parks and open spaces, urban nature is implicated in strategies of economic development, climate change mitigation and adaptation, public art, biodiversity enhancement, local food production, health and livability, social justice, community identity, and more.1 This “pluralization” of urban nature has come about in the last four

Simultaneous immunohistochemistry and autoradiography of peptides and 5-hydroxytryptamine in bird retina

A method was developed for the simultaneous demonstration of two specific cellular constituents. Cryostat sections of formaldehyde fixed tissue from retinae treated with ((3)H)-5-hydroxytryptamine were subjected to immunohistochemistry and subsequent autoradiography. The method takes advantage of the very efficient and specific uptake mechanism that many types of neurons possess which makes it pos

Review of measures for improved energy efficiency in production-related processes in the aluminium industry – From electrolysis to recycling

The aluminium industry is facing a challenge in meeting the goal of halved greenhouse gas emissions by 2050, while the demand for aluminium is estimated to increase 2–3 times by the same year. Energy efficiency will play an important part in achieving the goal. The paper's aim was to investigate possible production-related energy efficiency measures in the aluminium industry. Mining of bauxite and

Pathophysiology of type 2 diabetes and the impact of altered metabolic interorgan crosstalk

Diabetes is a complex and multifactorial disease that affects millions of people worldwide, reducing the quality of life significantly, and results in grave consequences for our health care system. In type 2 diabetes (T2D), the lack of β-cell compensatory mechanisms overcoming peripherally developed insulin resistance is a paramount factor leading to disturbed blood glucose levels and lipid metabo

Influence of variable oxygen concentration on the combustion derived release of radiocesium from boreal soil and peat

Radiocesium, 137Cs, is one of the most common and dispersed human-made radionuclides. Substantial stocks of 137Cs are stored in organic layers, like soils and peat, as a consequence of nuclear weapons fallout and accidental releases. As climate warming progresses these organic layers are subject to enhanced risks of wildfires, especially in the vast boreal biome of the northern hemisphere. Reemiss

Does delivery service differentiation matter? Comparing rural to urban e-consumer satisfaction and retention

In the context of continuously growing e-commerce and the rising global count of e-consumers, e-retailers and logistics service providers need to differentiate and tailor their offerings to refine their operations and meet e- consumers’ needs. This study investigates how e-consumers’ residential-area type affects the satisfaction with delivery services and reuse intentions in relation to e-consume
