The mass flow of air through an opening in a well-mixed compartment fire can be calculated with a simple expression. Similar simple models are lacking for the stratified pre-flashover case. Usually an advanced computer model is required to calculate the mass flow through an opening in a pre-flashover compartment fire. However, two equations for the opening mass flow through an opening are presente

Steady state and time-resolved absorption and fluorescence spectroscopy have been used to investigated the energy transfer in photosynthetic purple bacteria. Picosecond light pulses were used in measurements of Rb. sphaeroides WT and a LH1-deleted mutant, demonstrating that the energy trapping into the reaction center in both species occur on the same time-scale, and that the excitation energy is

Jane Eyre is perhaps the best known governess charatcer in nineteenth-century fiction, but as this article shows, Charlotte Brontë's heroine differs radically from the common depiction of governesses at the time. After an outline of the genre characteristics of the governess novel this article offers a close reading of some scenes in Jane Eyre in order to establish to what extent the novel can be

This paper presents three mathematical formulations for designing robust two-layer networks carrying elastic traffic. The formulations differ by the way flow reconfiguration is performed in the case of link failures. An iterative algorithm to solve the problems is given and an extensive numerical study is provided comparing the effectiveness of the three reconfiguration approaches. The formulation

In this paper, heat and mass balances of the intercooler in a 100 kW Proton Exchange Membrane Fuel Cell (PEMFC) system are analyzed by employing a commercial software IPSEpro. The compressor, ambient temperature, the humidification method and the PEMFCs cathode operating temperature were considered as the parameters influencing the heat and mass balances in the intercooler. Parametric studies of t

Risk management is an important process for public service organizations to maintain a high quality of service. However, many organizations are not satisfied with the result from risk handling. This paper proposes changes to a risk management model by integrating service level agreements into it. This makes responsibilities more clear to all parties involved in risk management. This paper also int

Popular Abstract in English Bolivia, as with other Latin American countries, is considered to be in an epidemiological transition due to the continued persistence of infectious diseases, and nutritional deficiencies related to poverty and food insecurity, together with an increase in chronic non-communicable diseases mainly related to lifestyle factors. The work presented in this thesis was focuseThe synergistic relation between nutritional deficiency and infection may have negative effects on the immune system, making individuals more vulnerable to infection. Zinc can affect the resistance to infections by modulating cytokine release, and by acting as a cofactor of thymulin, which induces the differentiation of immature T lymphocytes. To investigate the modulation of the immune response b

Global competition forces companies to constantly increase the efficiency in their production systems. One important factor affecting the production performance is the inbound materials handling system. When designing or relocating a manufacturing system, the cost of the material handling system is one of many things to take into consideration. In connection with on-going research a comprehensive

The paper deals with durability of Self-Compacting Concrete with limestone filler during Thaumasite Sulphate Attack. For this purpose six concrete with varying amounts of limestone filler, particle size of limestone filler, pressure height during casting and mixing order were studied. One normal concrete (without limestone filler) with vibrator compaction was studied in parallel. In the ongoing ex

This book discusses the concept of a queer feminism, a possible negotiation between queer theory and feminism.

The article investigates translation culture in the Swedish dominion Swedish Pomerania during the eighteenth century, with a particular focus on periodicals.
