Summarizes the possibilities offered by high performance liquid chromatography (HPLC) and capillary electrophoresis (CE) for the estimation of dissociation constants of weak protolytes. Methods used to study acidobasic equilibria; Estimation of dissociation constants by reversed-phase chromatography; Advantage of using HPLC; Estimation of dissociation constants by capillary electrophoresis.

We demonstrate the monolithic integration of a buried heterostructure semiconductor optical amplifier (SOA) and a deep ridge PIN photodiode for high-speed on-off keying links at 1.55 μm. The structure allows separate optimization of the SOA and the photodiode. The integrated receiver presents simultaneously a peak responsivity of 88 A/W with a low polarization dependence loss (<; 1 dB), a low noise figure (8.5 dB), and a wide 3-dB electrical bandwidth (≈ 50 GHz). This corresponds to a very large gain-bandwidth product of 3.5 THz. To our knowledge, this is the first time that a monolithically integrated SOA-PIN receiver has achieved such performances.

Introduction Suicide loss requires more time to grieve than other losses and it is often associated with suicidal thoughts and suicide attempts in the survivors. Objectives Survivors are often neglected and there is no real understanding of the both psychological and psychopathological consequences of loosing a dear one by suicide. Aims To assess the relationship between hopelessness, depression, suicide risk, complicated grief, intrusive memories and avoidance in a sample of suicide survivors. To define the permanence of particular variables associated with a specific type of loss, defined “complicated grief”, even after many years from the loss. Methods We recruited 35 survivors of suicide, searching for help to the Suicide Prevention Centre of Sant’Andrea Hospital in Rome. Subjects were administered BDI II, BHS, ICG, BRFL, IES, SHS, SWLS and an informative schedule. Results A total of 62.8% of the survivors shows a higher scores on Complicated Grief referred more intrusiveness of thoughts and memories (rho = 0.6; P < 0.01) and the attempt to prevent the thoughts and emotions related to the event (rho = 0:42; P <0.05), more depressive symptoms (rho = 0:53; P <0.01) and increased hopelessness (rho 0.54; P <0.01), a lower feeling of happiness (rho = –0.60; P <0.01) and satisfaction with their life (rho = –0.57; P < 0.01) than survivors that reported a lower scores in the complicated grief. Conclusions The permanence of the symptoms of complicated grief suggests that in the case of suicide is harder to achieve a degree of acceptance and emotional balance, which usually happens within six months from the loss.
