- This paper provides an industrial-scale technical assessment of absorption of CO2 in water to react into bicarbonate (HCO3−), with the goal of storing HCO3− in the oceans as a carbon sequestration technology. A potential advantage of the process is that it will not require a CO2 transport and storage infrastructure that will be expensive for small-scale and remote emission sources. Process simulations are utilized to estimate absorber column length and for mass flow estimations of water and base required for a target capture rate of 90%. The results indicate that the process is technically feasible under specific conditions, with pH regulation being highly important, although the demand for base represents a limiting factor. Yet, a potential niche for the process is CO2 capture at smaller plants emitting small amounts of CO2.

Bok (populärvet., debatt m.m.)abstract
- Människan mäter sig nu med naturen i att förändra klimatet, livets villkor och dess utveckling. Jorden är en utsatt planet, inte bara genom människans framfart utan också genom krafter utifrån och ett bombardemang av strålning, partiklar och kroppar från rymden. Miljön formas genom en mångfald processer som verkat sedan jorden bildades för 4,6 miljarder år sedan.Jord, vatten, luft, eld är en pedagogisk och medryckande berättelse om vår värld, från atomerna som utgör våra kroppar till galaxerna som omger oss.

- Objective:The objective of this study was to investigate the prevalence of concomitant hypertension and psychiatric disorders in the general population, using administrative healthcare data in Stockholm County.Design and method:The study population, included all living persons who resided in Stockholm County 1 January 2011 (N=2058408). Individuals with a diagnosis of hypertension were identified with data from all consultations in primary care, specialized outpatient care, and inpatient care 2009-2013. As outcome, data were obtained on all consultations because of certain psychiatric diagnoses between 2011 and 2013, including specifically depression, anxiety disorders, bipolar disorder, and schizophrenia. Age-adjusted odd ratios (ORs) with 95% confidence intervals (95% CI) were calculated for men and women with and without hypertension, with individuals without hypertension as referents.Results:The age-adjusted ORs for depression in persons with hypertension were 1.293 (95% CI 1.256-1.331,) for men and 1.036 (95% CI 1.013-1.058) for women. The age-adjusted ORs for anxiety in persons with hypertension were 1.279 (95% CI 1.238-1.322) for men and 1.050 (95% CI 1.024-1.076) for women. The OR for bipolar disease were 0.904 (95% CI 0.826-0.990) for men and 0.709 (95% CI 0.656-0.767) for women. For schizophrenia, the ORs were 0.568 (95% CI 0.511-0.632) for men and 0.537 (95% CI 0.478-0.603) for women.Conclusion:Increased awareness of the risk of depression and anxiety among hypertensive patients is needed to combat hypertension, its complications, and psychiatric suffering in the population. Hypertension is probably underdiagnosed and neglected in individuals with severe psychiatric disorders. We warrant efforts to integrate psychiatric and hypertensive care.
