We have carried out a prospective, longitudinal 30-year review of 95 adolescents who underwent total meniscectomy in one knee, and have compared the results with those observed 13 years earlier. All the medical records were scrutinized. Of the 63 patients reviewed clinically, 47 reported decreased sporting activity, although subjective satisfaction rose by 3% to 71%. The scores on the WOMAC ostcoa

The solution of generic dynamic optimization problems described by Modelica, and its extension Optimica, code using direct collocation methods is discussed. We start by providing a description of dynamic optimization problems in general and how to solve them by means of direct collocation. Next, an existing implementation of a collocation algorithm in JModelica.org, using CasADi and IPOPT, is pres

How should one understand comparisons in which neither of two alternatives is at least as good as the other? Much recent literature on comparability problems focuses on what the appropriate explanation of the phenomenon is. Is it due to vagueness or the possibility of non-conventional comparative relations such as parity? This paper argues that the discussions on how to best explain comparability

In Swedish child welfare, there are no mandatory guidelines on what interventions to use. Local authorities are able to set their own criteria for implementing or designing interventions. We carried out a survey to identify interventions in use in Children's Social Services and Child and Adolescent Psychiatric Care in Sweden. A total of 102 interventions were stated to have been in use, with betwe

Polymerized small molecular acceptor (PSMA) based all-polymer solar cells (all-PSC) have achieved power conversion efficiencies (PCE) over 16%, and the PSMA is considered to hold great promise for further improving the performance of all-PSC. Yet, in comparison with that of the polymer donor, the photophysics of a polymerized acceptor remains poorly understood. Herein, the excited state dynamics i

This brief puts forward three foundational principles that explain the difficulties in regulating multinational enterprises. This has implications on whether more or less coercive strategies could be pursued to ensure responsible business conduct. The task of regulating lead firms should remain mindful of fundamental considerations of corporate law (legal separation of entities), international law

Repurposing former industrial sites to creative uses (so-called 'creative reuse') contributes to both cultural heritage and environmental sustainability, as it maintains the existing building stock. Creative reuse may also have positive impacts on the site surroundings. This study explores the prerequisites, functioning, and consequences of creative reuse in a small post-industrial town in Sweden.

There is growing evidence that the environment experienced by one generation can influence phenotypes in the next generation via transgenerational plasticity (TGP). One of the best-studied examples of TGP in animals is predator-induced transgenerational plasticity, whereby exposing parents to predation risk triggers changes in offspring phenotypes. Yet, there is a lack of general consensus synthes

China became one of the biggest players in the global extractive resource supply chain, along with increasing extractive resource demand for green industries. Interestingly, over the last two decades, Chinese actors started participating in transnational extractive governance initiatives (TEGI) supporting transparency, a norm for governance-by-disclosure. This article aims to answer the question o

In this work, we report the aggregation-induced emission in a polymeric donor material poly(bis(2-butyloctyl)[2,2′:5′,2″-terthiophene]-4,4″-dicarboxylate-5,5′-diyl-vinylene) (PTVT-T), which exhibits a high device performance for the application of photovoltaics. Time-dependent density functional theory calculations and steady-state and time-resolved spectroscopy have been employed to reveal the un

Generic generalisations like ‘Opioids are highly addictive’ are very useful in scientific communication, but they can often be interpreted in many different ways. Although this is not a problem when all interpretations provide the same answer to the question under discussion, a problem arises when a generic generalisation is used to answer a question other than that originally intended. In such ca

IntroductionThe development of neutralising (inhibitors) and non-neutralising antibodies (NNAs) is a complication to factor replacement therapy in haemophilia. The diagnostic methods available lack standardisation, have high inter-laboratory variation, and false-negative as well as false-positive results may affect treatment. Both functional inhibitors and NNAs may be detected with higher reproduc

Benthic nitrogen fixation has been estimated to contribute 15 Tg N year(-1) to the marine nitrogen budget. With benthic marine nitrogen fixation being largely overlooked in more recent surveys, a refocus on benthic diazotrophy was considered important. Variations in nitrogenase activity (acetylene reduction-gas chromatography) in a tropical lagoon in the western Indian Ocean (Zanzibar, Tanzania) w
