Atrazine removal using adsorption and electrochemical regeneration.

This paper demonstrates the removal of atrazine using a novel carbon-based adsorbent to below 1.0 microg l(-1) and its subsequent electrochemical regeneration in a simple electrochemical cell. Effective electrochemical regeneration can be achieved with a treatment time as low as 20 min over a number of adsorption/regeneration cycles using laboratory-prepared solutions. The results suggest that electrochemical modification of the particulate surface on electrochemical regeneration can result in adsorptive capacities three times greater than originally achieved.

Relationships between infant crying, birth complications, and maternal variables.

The aim of the study is to identify factors influencing infants' crying behaviour (total crying duration, length of crying bouts, and frequency of crying). The searching for variables explaining inter-individual differences requires a sufficient stability of the cry parameters at least over short time intervals. Thus, a second aim is to assess the intra-individual stability of the crying behaviour in an age range from 3 to 12 months. Sixty-two mother-child dyads participated in the study. The results show substantial stabilities of the crying behaviour of infants between 3 and 12 months of age. This is related to the amount of crying as well as to the pattern of crying shown by the children over a 24 h interval. The typical cry pattern is characterized by peaks at 12.00 h and early in the evening, although there are large individual differences between the children with regard to cry durations at each hour of the day. Regarding the cry durations at 3 months of age, birth complications and the perceived emotional atmosphere in the mothers' family of origin are the major contributing factors.

Intuitive parenting and infant behavior: concepts, implications, and empirical validation.

On the basis of the concept of intuitive parenting, the expectation was formulated that a mother's tendency to reflect on her parenting behavior would impede intuitive responses to infant signals. Also, a high quality of parental interactional behavior was expected to be related to fewer problems of the child (e.g., less crying, fewer reported difficulties, fewer health problems). An observational study with 62 mothers and their 3-month-old children confirmed the assumption that reflection about parenting during face-to-face interactions interferes with intuitive behavior. However, in contrast to initial expectations, a high quality of parenting was related, not to fewer, but rather to more health and behavioral problems of the child. Conceptual differentiations of the initial assumptions are discussed.
