Menopause Awareness, Symptoms Assessment and Menqol Among Bahrain Women

Menopause is a normal physiological process of the permanent cessation of ovarian hormone reproduction, thereby offending the regular menstrual cycle. Critical period in women’s life occurs 40 to 60 years. Frequently reported symptoms are physiological disturbances, psychological complaints including mood swings and& other changes that may impair the overall quality of life. Menopausal symptoms significantly reduce the Quality of Life (QOL) and further worsens with more severity of the condition. The aim of this study was to assess the menopausal awareness and related symptoms that affects the quality of life. Methods: A cross-sectional community survey design was adopted among 128 women through convenience sampling by using Menopause awareness scale and MenQol. Results: The domain-wise prevalence of symptoms score on vasomotor was 51.5%(66), psychosocial 35.2%(45), 44.5%(57), sexual 25.8%(33) and others 44.5%(57). Overall score was 40.6%(52). In relation to menopause awareness, low 7.8 % (10), Moderate 82.0% (105) and high 10.2%(13).Conclusion: Menopause awareness programs need to be initiated at the community level for better health and the Quality of Life.

Energy arbitrage of hydrogen-bromine flow battery between the day-Ahead and imbalance electricity markets considering price uncertainty

\u3cp\u3eIn this paper, a stochastic model is presented to investigate arbitrage between the day-Ahead market (DAM) and the imbalance market (IM) for electricity considering uncertainty of prices. The revenue of arbitrage is calculated for a type of flow batteries, namely Hydrogen-Bromine (HBr) batteries. In order to model uncertainty, scenarios are generated by analyzing the real electricity prices. The required number of scenarios is determined through an iterative algorithm that adds scenarios in each iteration until the normalized change in revenue is less than the predefined value. The simulation is done based on the Dutch DAM and IM electricity prices and revenues are calculated for HBr batteries with different parameters. Also, the investment cost, operation cost, and the connection cost are compared with the calculated revenues and an estimation of the gained profit is reported.\u3c/p\u3

Investigation of arbitrage between the Dutch day-ahead and imbalance markets as a business case for the hydrogen bromine flow battery

The role of energy storage as a means to support power systems in the light of increasing penetration of renewable energy sources is already recognized. A large number of scientific studies highlight the potential benefits, while transmission and distribution system operators actively engage in numerous pilot projects. However, independent investors might be reluctant to invest in energy storage, mainly due to factors such as the high investment cost, the relatively limited service life of storage technologies and the absence of clear business cases within the current regulatory framework. In this paper, arbitrage between the day-ahead and the imbalance markets is investigated to identify a potential business opportunity for a hydrogen bromine redox flow battery. Based on an actual commercial solution, the analysis for the Dutch electricity market reveals the potential for a positive business case under certain assumptions
