    Notes: Cerium oxides are used as surrogates for plutonium oxides because of the similarities in their thermodynamic properties. In this study, the stability limits of both CeGaO3 and PuGaO3 with respect to the partial pressure of oxygen and temperature have been predicted by theoretical calculations. Using the results of the calculations as guidance, mixtures of CeO2 and Ga2O3 have been prepared and thermally treated at 1273, 1473, and 1673 K, in atmosphere of air, argon, or Ar–6% H2. In the samples annealed under low oxygen partial pressures, the CeGaO3 perovskite-type compound was identified. Based on Rietveld structure refinement, the orthorhombic space group (Pnma, 62) was confirmed.

    Notes: In force measurements with the atomic force microscope (AFM) often nonelastic deformations of the sample are observed. This is especially the case for AFM experiments on ice. In this paper two theoretical approaches are used to calculate the indentation of the tip. First, in an extended plastic indentation model we assume that the pressure exerted by the tip plastifies the sample material once the pressure exceeds three times the yield stress. The rate of plastification limits the indentation speed. With two parameters this model adequately describes measured force curves on ice in a temperature range of −4°C to −20°C and for driving speeds of 0.8 to 110 μm/s. The calculation also shows that in general plastic deformation can lead to different force curves depending on the driving speed. For low driving speeds a jump-in and a linear force curve is expected. For fast driving speeds plastic deformation leads to curved force curves with gradually increasing slope. Second, in a hydrodynamic model we assume that the presence of the tip surface leads to an interfacial premelting of the ice. The flow of the liquidlike water out of the gap between tip and bulk ice is limiting the indentation speed of the tip. The hydrodynamic model does not fit measured force curves as good as the extended plastic indentation model and viscosities which are unrealistically high need to be assumed. Hence, we can exclude that a liquidlike layer of a thickness significantly larger than a monolayer exists in AFM experiments on ice. © 2000 American Institute of Physics.

    Notes: Brown flour was developed by incorporating different proportions of wheat bran, i.e. 0, 5, 10, 15 and 20 percent into the residual flour (milling by-product of pizza flour). Each treatment of brown flour, wheat bran and whole wheat flour was subjected for proximate composition and iron content. The highest iron content was observed in wheat bran i.e. 64.6mg/kg whereas iron content in different treatments of brown flour ranged from 16.8 to 29.2mg/kg. Phytic acid content ranged from 0.72 to 1.09g/100g in different flour treatments. Chapatties prepared from the respective flour samples were further evaluated for various chemical and sensory attributes. The brown flour prepared by the addition of 10 percent bran showed better performance and was quite comparable with whole wheat flour regarding the proximate and sensory attributes like color, flavor, texture, taste, folding ability, chewing ability and appearance. Moreover, the same sample (T3) had better iron content than whole wheat flour. Chapatties prepared with brown flour containing 10 percent followed by 15 percent bran were of best quality and quite comparable with chapatties prepared from whole wheat flour.

    Notes: Use of red palm oil fortified shortening was explored for combating vitamin A deficiency in Pakistan. Six types of cookies were prepared in which normal shortening was progressively replaced at the rate of 20 per cent with RPO fortified shortening. The carotenoids content of cookies varied depending on the content of RPO. A moderate loss was noticed after a 60-day storage. An increase in moisture content was observed, while other chemical characteristics remained unchanged. Sensory analysis showed that cookies containing 40 per cent RPO were most acceptable, while those prepared from 80-100 per cent RPO developed an oily flavour. The best treatment having 40 per cent RPO?+?60 per cent NS provides 344.15 to 312.86 µg/10?g of carotenoids at 0 and 60 days respectively. Recommends that five cookies would provide 40-50 per cent of RDA of vitamin A to school-going children.

    Notes: In this study, we investigated the kinetics and products of the oxidation of MoSi2 powder with an average particle size of 1.6 μm at 900°, 1000°, and 1100°C, using a small sample size of 0.5 g. Such a small sample size allowed us to minimize the effect of oxygen transportation through the powder volume, while maintaining a good relative weighing accuracy. X-ray diffraction of oxidized samples indicated the formation of Mo5Si3 and Mo metal. Analysis of the oxidation kinetics suggested that gaseous MoO3 formed initially and amorphous SiO2 film later. The oxidation kinetics and products observed in this study differ from those reported in an early study, in which a larger sample size was used.

    Notes: [Auszug] It is thought that Galactic cosmic-ray nuclei are gradually accelerated to high energies (up to about 300 TeV per nucleon, where 1 TeV is 1012 eV) in the expanding shock waves connected with the remnants of powerful supernova explosions. However, this ...

    Notes: Food security is a broad concept, encompassing issues related to the nature, quality, and security of the food supply as well as issues of food access. The world has been facing a paradox of widespread food insecurity and malnutrition amid net food surpluses. Increased food supplies do not automatically enhance access to food by the poorer groups of society. Food security measures alone may have a limited effect on the nutritional well being of individuals, unless the reinforcing detrimental linkages between food insecurity, disease, poor sanitation and inadequate education are addressed. Current theory holds that good nutrition for pre-schoolers depends on household food security, an adequate health environment, and adequate maternal and childcare. Pakistan is a low-income developing country with a per capita income of US$443, one of the lowest in the world. Pakistan is not a food insecure country. It generally has the economic ability to import the required food. This paper considers the main features of determinants of food security in Pakistan, particularly household economy assessment, and looks at what conclusions can realistically be drawn out of analysis when conducted within a conceptual framework.

    Notes: The role of care as a critical influence on child nutrition, health, and development has received increasing attention in the last decade. While the role of care has been well elaborated at a conceptual level, we still lack simple valid and reliable tools to measure many aspects of care. Psychosocial care includes the behaviors and practices that support children's healthy growth and psychosocial development. The research presented here constitutes one of the first attempts to quantify some of the various dimensions of child-care practices (namely type, quality, and frequency) and to summarize the information into a composite, age-specific index of child-care practices. The main purpose of this research is to examine, specifically within the context of Pakistan, which of the maternal and household characteristics constituted more severe constraints to the provision of good child care. The main findings of this research have important policy implications. They suggest that specific training in child feeding and the use of preventive health services for poor mothers with little formal education could have a large impact on the growth of children living in impoverished environments.
