Effects of frying parameters on physical changes of tapioca chips during deep-fat frying

The interrelationships of the effects of frying time, oil temperature, and initial moisture content on moisture loss, oil absorption, and linear expansion of a tapioca starch chip half-product during deep-fat frying have been studied. Both oil absorption and linear expansion were affected, in different ways, by moisture loss. Oil absorption was essentially a quantitative water replacement process. On the other hand, linear expansion occurred as a result of rapid vaporization of water in the initial stages of frying, but reached a plateau before maximum moisture loss. Critical frying times, temperatures, and initial moisture contents, below which virtually no physical change occurred, were observed. The optimum set of frying parameters for maximum linear expansion appears to be a frying time of 40 s, an oil temperature of 200°C, and an initial moisture content of 15% (dry basis).     

Stability analysis of four bar mechanism. Part II— taking damping into consideration

In[1], a technique is developed to study the stability of the mechanism having elastic links, where damping is not taken into consideration. Here we develop a technique to study the stability of the practical four bar mechanism, taking damping into consideration. The system behaviour is studied at various speeds in different regions. Also the comparison of damped and undamped displacement responses is presented.

Children conceived by gamete donation: Psychological adjustment and mother-child relationships at age 7.

An increasing number of babies are being born using donated sperm, where the child lacks a genetic link to the father, or donated eggs, where the child lacks a genetic link to the mother. This study examined the impact of telling children about their donor conception on mother-child relationships and children's psychological adjustment. Assessments of maternal positivity, maternal negativity, mother-child interaction, and child adjustment were administered to 32 egg donation, 36 donor insemination, and 54 natural conception families with a 7-year-old child. Although no differences were found for maternal negativity or child adjustment, mothers in nondisclosing gamete donation families showed less positive interaction than mothers in natural conception families, suggesting that families may benefit from openness about the child's genetic origins.

Parenting Infants Conceived by Gamete Donation.

In recent years, concerns have been raised regarding the potentially negative consequences of gamete donation for parent-child relationships. Findings are presented of a study of families with an infant conceived by gamete donation. Fifty donor insemination families and 51 egg donation families were compared with 80 natural conception families on standardized interview and questionnaire measures of the psychological well-being of the parents, the quality of parent-child relationships, and infant temperament. The differences that were identified indicated more positive parent-child relationships among the gamete donation than the natural conception parents, accompanied by greater emotional involvement with the child. Comparisons were also carried out between the donor insemination and the egg donation parents on their experiences of gamete donation. In contrast to the findings of earlier investigations, the donor insemination and egg donation parents appeared to be more open toward disclosing the donor conception to the child. It was concluded that infants conceived by egg or sperm donation did not appear to be at risk for parenting difficulties. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Stability analysis of four bar mechanism. Part I— With the assumption that damping is absent

With increasing machine speed, rigid link assumption is no more valid, hence, links of the mechanism are subjected to vibration. Stability analysis of a vibrating system gives the speeds at which the system response is unbounded. It is necessary to avoid these speeds or to provide sufficient damping for better performance of the system. This paper presents the theoretical work done for stability analysis, which is simple and can be extended to any mechanism in general. It gives the speed ranges, in which response is unbounded, and presents the study of the response at various speeds for undamped system.     

Families created through surrogacy: Mother–child relationships and children's psychological adjustment at age 7.

Each year, an increasing number of children are born through surrogacy and thus lack a genetic and/or gestational link with their mother. This study examined the impact of surrogacy on mother–child relationships and children's psychological adjustment. Assessments of maternal positivity, maternal negativity, mother–child interaction, and child adjustment were administered to 32 surrogacy, 32 egg donation, and 54 natural conception families with a 7-year-old child. No differences were found for maternal negativity, maternal positivity, or child adjustment, although the surrogacy and egg donation families showed less positive mother–child interaction than the natural conception families. The findings suggest that both surrogacy and egg donation families function well in the early school years. (PsycINFO Database Record (c) 2011 APA, all rights reserved)
