Ventilation/perfusion single photon emission computed tomography (V/P SPECT) is the recommended method for proper diagnosis of pulmonary embolism (PE), according to the European Association of Nuclear Medicine (EANM) guidelines. Adequate V/P SPECT acquisition starts with ventilation and continues immediately with perfusion. The whole procedure takes 20min by using an optimal combination of nuclide

Soils are essential for life and civilization. They have a long history of political attention, documented at least since Ancient Greece and the Roman Empire. Soil played a key political role in the founding of the USA but gradually lost its clout in the last hundred years. The recent IPCC Special Report on Climate Change and Land may symbolize a return of soils to the political arena. The renewed

Company cars are commonly defined as cars given by an employer to an employee for the purpose of covering transport needs related to a specific job, such as to visit clients. However, company cars are commonly understood as a form of additional income, for instance in terms of opportunities to drive a specific (larger) car model, and because the car can also be driven privately or by family member

In a typical Nigerian village, the majority of the population comprises old people who are mostly economically unproductive due to reduced or loss of physical strength brought about by ageing and ill health. Many of these rural old people still work, and do so outside the formal sector, and are particularly susceptible to the effects of climate variability and change. Few studies have reported on

Occupational dermatosis are common all over the world. The prevalence depends on many factors including whether the legal system acknowledges both causation and aggravation of occupational dermatosis.

Stopped-Flow Light Scattering (SFLS) is a method devised to analyze the kinetics of fast chemical reactions that result in a significant change of the average molecular weight and/or in the shape of the reaction substrates. Several modifications of the original stopped-flow system have been made leading to a significant extension of its technical applications. One of these modifications allows the

OBJECTIVES: To examine the relation between adherence to dietary guidelines and the risk of developing rheumatoid arthritis (RA).METHODS: Participants in the Malmö Diet and Cancer study (MDCS) cohort diagnosed with RA were identified through register linkage and validated in a structured review. Four controls per case were selected, matched for sex, year of birth, and year of inclusion in the MDCS

Based on the Fenchel duality we build a primal-dual framework for minimizing a general functional consisting of a combined L1 and L2 data-fidelity term and a scalar or vectorial total variation regularisation term. The minimization is performed over the space of functions of bounded variations and appropriate discrete subspaces. We analyze the existence and uniqueness of solutions of the respectiv
