Summary1. Plasma thromboplastin has been formed from a mixture of pigs’ plasma, serum and platelets using a modification of the thromboplastin generation system of Biggs and Douglas (1953). The thromboplastic activity in the modified system was more stable than in the original system.2. A sediment with considerable thromboplastic activity has been obtained by centrifugation. This sediment was free of platelets and contained very little thrombin.3. The sediment when resuspended in buffer was fully active only in the presence of calcium and between pH 6.6 and 7.0. The activity slowly decreased at 0—4° C and rapidly at 65° C.4. The sediment rapidly converted prothrombin to thrombin in the absence of factor V.5. The activity of the sediment was unaffected when it was incubated with thrombin.

In this study a new multi-generation system which generates power (electricity), thermal energy (heating and cooling) and ash for agricultural needs has been developed and analysed. The system consists of a Biomass Integrated Gasification Combined Cycle (BIGCC) and an absorption chiller system. The system generates about 3.4 MW electricity, 4.9 MW of heat, 88 kW of cooling and 90 kg/h of ash. The multi-generation system has been modelled using Cycle Tempo and EES. Energy, exergy and exergoeconomic analysis of this system had been conducted and exergy costs have been calculated. The exergoeconomic study shows that gasifier, combustor, and Heat Recovery Steam Generator are the main components where the total cost rates are the highest. Exergoeconomic variables such as relative cost difference (r) and exergoeconomic factor (f) have also been calculated. Exergoeconomic factor of evaporator, combustor and condenser are 1.3%, 0.7% and 0.9%, respectively, which is considered very low, indicates that the capital cost rates are much lower than the exergy destruction cost rates. It implies that the improvement of these components could be achieved by increasing the capital investment. The exergy cost of electricity produced in the gas turbine and steam turbine is 0.1050 £/kWh and 0.1627 £/kWh, respectively. The cost of ash is 0.0031 £/kg. In some Asian countries, such as Indonesia, ash could be used as fertilizer for agriculture. Heat exergy cost is 0.0619 £/kWh for gasifier and 0.3972 £/kWh for condenser in the BIGCC system. In the AC system, the exergy cost of the heat in the condenser and absorber is about 0.2956 £/kWh and 0.5636 £/kWh, respectively. The exergy cost of cooling in the AC system is 0.4706 £/kWh. This study shows that exergoeconomic analysis is powerful tool for assessing the costs of products.

As destination of choice for many short-term study abroad programs, Berlin offers students of German language, culture and history a number of sites richly layered with significance. The complexities of these sites and the competing narratives that surround them are difficult for students to grasp in a condensed period of time. Using approaches from the spatial humanities, this article offers a case study for enhancing student learning through the creation of digital maps and itineraries in a campus-based course for subsequent use during a three-week program in Berlin. In particular, the concept of deep mapping is discussed as a means of augmenting understanding of the city and its history from a narrative across time to a narrative across the physical space of the city. As itineraries, these course-based projects were replicated on site. In moving from the digital environment to the urban landscape, this article concludes by noting meanings uncovered and narratives formed as we moved through the physical space of the city.

Ethnohistorians and other scholars have long noted how European colonial texts often concealed the presence and participation of indigenous peoples in New World conquests. This scholarship has examined how European sources (both texts and maps) have denied indigenous history, omitted indigenous presence, elided indigenous agency, and ignored indigenous spaces all while exaggerating their own power and importance. These works provide examples of colonial authors performing these erasures, often as a means to dispossess. What they lack, however, is a systematic means of identifying, locating, and measuring these silences in space and time. This article proposes a spatial history methodology which can make visible, as well as measurable and quantifiable the ways in which indigenous people and spaces have been erased by colonial narratives. It presents two methods for doing this. First, narrative analysis and geovisualization are used to deconstruct the imperial histories found in colonial European sources. Second it combines text with maps to tell a new (spatial) narrative of conquest. This new narrative reconstructs indigenous activity through a variety of digital maps, including ‘mood maps’, indigenous activity maps, and maps of indigenous aid. The resulting spatial narrative shows the Spanish conquest of Peru was never inevitable and was dependent on the constant aid of immense numbers of indigenous people.
