It was found that SeB had the capacity to inhibit the metabolic growth of Escherichia coli. But in different sol-vent, the extent of inhibition is different. Removing the effect of solvent, we obtained the half-inhibition conce.ntra-tion(IC50) of SeB from the power-time curves. The value of IC50 of SeB was 1319μg ·mL-1.展开更多

It shows that there is a one to one correspondence between 2m GHZ states for a quantum system ofm(m ≥ 2) nodes and 2m oriented links of the linkage N1 in knot theory, where N = 4 C2m = 2m(m - 1) is the numberof crossings of the link with m components, the subscript 1 denotes the order of the unoriented m components link withN crossings, i.e. the first type, actually the simplest type.展开更多

However, there are gaps in understanding about what works to facilitate and enable this behavior change i.e. , the mechanisms of actions underpinning social prescribing delivery. This study used a qualitative approach involving interviews with 18 Social Prescription Link Workers (SPLWs). Reflective thematic analysis was used to analyze the data. Through this, an overall theme of “Theoretical underpinning: Solution-focused and strengths-based” was identified. This was made up of sub-themes relating to mechanisms underpinning: the SPLWs’ role (comprising asking questions, motivational interviewing and the therapeutic alliance);the patients’ role, (empowerment and active engagement);and the approach adopted (solution building, goal and action orientated). To formalize this, a framework could be developed for SPLWs that encapsulates the solution-focused strengths-based approach for application within social prescribing. This framework can then be embedded into practice facilitating more successful healthy lifestyle behavior change for social prescribing patients.展开更多
