Cold start tests are carried out to evaluate the performance of copper-exchanged zeolites as hydrocarbon traps under simulated gasoline car exhaust gases, paying special attention to the role of copper in the performance of these zeolites. It is concluded that the partial substitution of the protons in the parent H-ZSM-5 zeolite is highly beneficial for hydrocarbon trapping due to the formation...

In this paper, we will explain how to perfectly hedge under Heston’s stochastic volatility 17 model with jump-to-default, which is in itself a generalization of the Merton jump-todefault model and a special case of the Heston model with jumps. The hedging instru19 ments we use to build the hedge will be as usual the stock and the bond, but also the Variance Swap (VS) and a Credit Default Swap (...

OBJECTIVE The paper examined the impact of maternal age at birth on under-5 death in Nigeria. METHOD Secondary data were generated from the 2003 Nigeria Demographic and Health Surveys in examining the relationship between maternal age at birth and under-5 mortality risk. Relationships between variables were tested through bivariate and logistic analyses. RESULTS Out of 7620 sampled women fo...

To assess the nutritional status of children under 5, a survey was conducted in the under-privileged community of Mahmoodabad. Of over 1,000 children, three-fourth had varying grades of protein calorie malnutrition. The prevalence of grade III malnutrition was higher in children in their 2nd year and among those belonging to families of more than four persons. On the average, a child was report...

T considerable interest in the chemistry and applications of metal−organic frameworks (MOFs) has led to significant synthetic advances in this area, yet the details of the self-assembly process that give rise to these materials are still unclear. This is curious, but not unexpected: the crystallization of MOFs is difficult to study because their nucleation typically requires unpredictable induc...

It is well established that stress leads to changes in the serotonergic system. In order to gain a better understanding of the effects of recurrent stressful experiences on the serotonergic system, changes in the 5-HT1A-receptor system resulting from different periods of psychosocial stress (PSS) were analyzed in the present study. Male tree shrews (Tupaia belangeri) were submitted to subordina...

To evaluate the completeness of registration of infant and child deaths in Egypt, reinterviews were conducted with families who had reported a death of a child under age 5 in the five years before the survey for two national surveys recently conducted in Egypt: the United Nations PAPCHILD survey of 1990-1991 and the Egyptian Demographic and Health Survey (EDHS) of 1992. The survey instrument in...

The magnetically ordered ground state of CeRhIn(5) at ambient pressure and zero magnetic field is an incommensurate helicoidal phase with the propagation vector k = (1/2,1/2,0.298) and the magnetic moment in the basal plane of the tetragonal structure. We determined by neutron diffraction the two different magnetically ordered phases of CeRhIn(5) evidenced by bulk measurements under applied mag...
