Abstract. To prevent the spread of COVID-19 epidemic, restrictions such as “lockdowns” were conducted globally, which led to a significant reduction in fossil fuel emissions, especially urban areas. However, CO2 concentrations areas are affected by many factors, weather, biological sinks and background fluctuations. Thus, it is difficult directly observe reductions from sparse ground observatio...

PURPOSE To determine whether continuous infiltration of local anaesthetic can reduce the pain score and morphine use over 48 hours after total knee arthroplasty (TKA). METHODS 11 men and 43 women aged 50 to 82 years who underwent unilateral TKA for osteoarthritis were recruited. They were randomised into 3 groups. In group 1, 17 patients who acted as controls received patient-controlled analg...

We investigated the possible use of acrylic cement containing chemotherapeutic drugs in the treatment of malignant lesions in bone. The diffusion of methotrexate (MTX) from methylpolymethacrylate implants was studied in vitro: polymerisation of the cement did not destroy the drug; liberation began immediately and about 10% was released by 18 hours. Some release continued for as long as six mont...

There is a large and growing literature that investigates evidence for mean reversion in stock prices. Empirically, there is no consensus as to whether stock prices are mean reverting or random walk processes; at best, the results are mixed. In this paper, we provide further evidence on the mean reversion hypothesis for seventeen European countries using the Levin and Lin (1992), seemingly unre...

Materials and methods: In Experiment One, 17 sows received equine chorionic gonadotropin (eCG; 600 IU) intramuscularly (IM) at weaning, then 5 mg pLH IM 80 hours later to induce ovulation. Time of ovulation was determined using transrectal real-time ultrasonography. In Experiment Two, 567 sows were assigned to five treatments: no hormone treatments, AI AM and PM day 5 after weaning; eCG at wean...
