Medicine and Surgery around Women's Cycle

-

Recent studies have suggested that the timing of surgery in relation to the menstrual cycle might influence survival of premenopausal women with operable breast cancer. The data of 96 premenopausal patients who underwent primary surgery for operable breast carcinoma between 1975 and 1988 were analysed. At 10 years, disease-free and overall survival rates of patients whose initial surgery was 1-12 days after the starting date of the last menstrual period (follicular phase) were significantly poorer compared with survival of those who underwent operation more than 12 days after the last menstruation (luteal phase) (disease-free survival rate 40 versus 72 per cent, P = 0.002; overall survival rate 40 versus 79 per cent, P = 0.001). These differences in survival remained significant in a second analysis based on the menstrual phase at the time of both initial and definitive operation. Menstrual phase had the greatest impact on the survival of patients with positive axillary nodes (P = 0.009). Prospective studies are required to elucidate the relationship between the timing of all surgical procedures during the menstrual cycle and survival.

Competition for talent

  Competition for talent As demand grows for new and emergent  skills , including UX design, cybersecurity, and data science, workers around the world — and labor markets — are struggling to keep up.  According to a recent  survey  conducted by the World Economic Forum, nearly eight in 10 global CEOs say they’re concerned about the availability of people with the right skills. So far, organizations have responded by engaging in a war for talent — that is, buying or stealing it, rather than growing it from within. As they compete to fill roles, many have been willing to spend billions on recruiting (or poaching), while reluctant to invest in training their existing workers or unskilled ones, perhaps out of fear their competitors will hire those newly attractive employees away.  Demand for skills as people retire early and pay levels depressed.

Carbon Capture & Storage

-
  Carbon Capture & Storage Carbon capture and storage (CCS) is the process of capturing and storing carbon dioxide (CO 2 ) before it is released into the atmosphere. The technology can capture  up to 90%  of CO 2  released by burning fossil fuels in electricity generation and industrial processes such as cement production. CO 2  can be captured using different methods. The main ones are: post-combustion, pre-combustion and oxyfuel. Post-combustion technology removes CO 2  from the flue gases that result from burning fossil fuels. Pre-combustion methods – carried out before burning the fossil fuel – involve  converting the fuel into a mixture of hydrogen and CO 2 .  Oxyfuel technology  produces CO 2  and steam by burning fossil fuels with almost pure oxygen. Post-combustion and oxyfuel equipment can be fitted to new plants or retrofitted – in other words, added to existing power stations that were originally built without it. Pre-combustion methods require large modifications to e
