Health and Safety Performance of UK Universities and How to Improve It.

Background: This research suggested a method for evaluating health and safety performance as a combination of reactive and active monitoring.

Methods: A number of Freedom of Information requests (FoI) were sent to the Health and safety Executive (HSE) and 100 UK universities. Data on the number of reportable incidents, diseases and dangerous occurrences were compiled for UK universities and combined with the Impact Ranking for good health and well-being.

Total synthesis of bryostatin 3.

Bryostatins are a family of 21 complex marine natural products with a wide range of potent biological activities. Among all the 21 bryostatins, bryostatin 3 is structurally the most complex. Whereas nine total syntheses of bryostatins have been achieved to date, bryostatin 3 has only been targeted once and required the highest number of steps to synthesize (43 steps in the longest linear sequence and 88 total steps).

[Prediction of Risk of Calcification of Heart Valve Bioprostheses on the Basis of Comprehensive Assessment of Recipients Clinical Factors and Their Compliance With Therapy].

Purpose: The development of the prediction methods of calcification risk of heart valve bioprostheses (BP) based on comprehensive assessment of the impact of clinical factors of the recipients and their adherence to medication.

Materials And Methods: We performed a retrospective study of clinical status and adherence to drug therapy of 170 recipients of heart valve BP with (n=63) and without (n=109) calcification. We used the method of comprehensive assessment of the analyzed parameters with estimation of prognostic coefficients for each of them, followed by calculation of integral indicators and construction on their basis of prognostic models for the various intervals of BP functioning.

The impact of ionic liquids on the coordination of anions with solvatochromic copper complexes.

Solvatochromic transition metal (TM)-complexes with weakly associating counter-anions are often used to evaluate traditional neutral solvent and anion coordination ability. However, when employed in ionic liquids (IL) many of the common assumptions made are no longer reliable. This study investigates the coordinating ability of weakly coordinating IL anions in traditional solvents and within IL solvents employing a range of solvatochromic copper complexes.

Ionic liquids for metal extraction from chalcopyrite: solid, liquid and gas phase studies.

We studied leaching of Cu and Fe from naturally occurring chalcopyrite ore using aqueous solutions of ionic liquids (ILs) based on imidazolium and ethylammonium cations and hydrogensulfate, nitrate, acetate or dicyanamide anions. Liquid, solid and gas phases of the leaching systems were characterised. We have shown that nonoxidative leaching is greatly dependant not only on temperature and pH, but on the anion species of the IL.
