    Anxiety indicators for women in the postpartum period
    (EDP Sciences, 2018) Sudraba, V.; Zemite, L.; Berkis, U.; Vilka , L.; Rīga Stradiņš University
    Situations, which are dangerous and sad, provoke state anxiety (S-anxiety), but trait anxiety (T-anxiety) shows anxiety like person’s acquired behavioural disposition. The aim was to evaluate postpartum anxiety indicators of women that have had the vaginal birth and women that have had surgery in Riga regional medical institutions that provide obstetric services. Respondents – 100 women (50 – with vaginal birth; 50 – with caesarean section surgery) were surveyed by 2 instruments: the demographic survey and the state – trait anxiety inventory, STAI Form Y-1 (Spielberger et al., 1983, adapted in Latvian by Škuškovnika (2004). The results reflect the statistical difference between State anxiety indicators (S-anxiety) of women that have had the vaginal birth (M=35.38; SD= 9.98) and women that have had the surgery (M=37.20; SD= 9.41) was not found (p=0.304). Indicators of Trait anxiety (T-anxiety) show that there was not statistically significant (p=0.059) difference between women that have had the vaginal birth (M=36.92; SD= 7.81) and women that have had the surgery (M=39.24; SD= 7.56), however, it should be noted that the average anxiety scores were higher after surgery.

    Injection of Renewables Gases Into the Existing Gas Distribution Grids and Employment of Reverse Gas Flow Technique
    (2024-04-01) Jansons, L.; Silina, J.; Bode, I.; Zemite, L.; Zeltins, N.; Palkova, K.; Faculty of Social Sciences
    Sustainability and longevity of existing gas grid exploitation perspective are closely related to two fundamental issues: their ability to adopt to changing gas fuel production and supply landscape in the context of methane-based fuels, mostly, biomethane, and in the context of non-methane-based fuels, mostly, low carbon and green hydrogen. Renewable gases and their ever-growing presence in gas transmission and distribution systems open up a discussion about the necessity to revise and restructure the original - vertically integrated layout of the gas systems, where gas supply is only technically possible from the transmission system towards distribution one, and not vice versa. Development of numerous decentralized biomethane production facilities connected to the gas distribution system causes a necessity to ensure the possibility to pass biomethane surplus of a certain production area into the gas transmission grid, thus avoiding necessity to install biomethane storage capacities locally and granting other regions an opportunity to use said surplus in their gas consumption immediately. The article addresses biomethane production trends and actions taken towards the development of reverse flow gas stations in France - one of biggest biomethane producers in Europe to date, and opportunities and challenges, which this technique might face in smaller and less active renewable gas markets as the one of Latvia.
