Nutritional and rheological properties of pumpkin seed based fruits spread

Fruit spread is prepared by combining sugar with processed fruit juice, concentrated fruit juice, or whole fruit. Pumpkin (Curcurbita maxima) seeds are commonly seen as industrial waste and discarded. Pumpkin seed was roasted and made into powder form.  β-carotene rich fruits such as mango, papaya, and muskmelon were used to extract the pulp. To obtain a desired consistency of fruit spread, the fruit pulp (25%) was blended with roasted seed powder (70%) Fruits were scattered at 5° to 10° Brix and sugar was added. To extend the shelf life and improve the quality of the spreads, they were pasteurised at 60°C for 30 minutes. The spreads were packaged in two different types of packaging material food grade glass containers and polypropylene containers. They were kept in refrigerated conditions at 4°C for further analysis. After organoleptic evaluation, the fruits spreads were analysed for nutritional content, textural properties and microbial content. Pumpkin seed based fruit spreads have 15.23 to 15.64% moisture, 6.7 to 7.18 %  protein, 4.53  to 4.89% fat, 5.29 to 5.69% fiber and 15.36  to 28.67% carbohydrates. The pumpkin seed based fruit spreads had 15.41 to 23.04°Brix of total soluble solids. The fruit spreads had 85.82 to 764.54 g hardness, -88.54 to-205.45 g adhesiveness, 0.87 to 0.95 springiness,0.48 to 0.74 cohesiveness, 64.78 to 344.06 gumminess and 61.53 to 311.64 chewiness. The pumpkin seed based fruits spread had viscosities of 2.21 to 3.58 centipoises. The mango based fruit spreads had the highest score values among the fruit spreads. The fruit spread encompassed enormous bioactive compounds when compared to other fruit spreads available on the market

Osmotic Drug Delivery System: A Review

Osmotic drug delivery uses the osmotic pressure level for controlled delivery of drugs by using osmogens. Osmotic systems for controlled drug-delivery applications are well established, both in human pharmaceuticals and in veterinary medicine. The process of osmosis that can control the drug delivery system. Osmotic pressure created from external environment into the dosage form regulates the delivery of drug from osmotic device. Osmotic pumps are promising systems for controlled drug delivery. The systems are used for oral administration and implantation. Osmotic pumps consist of an inner core containing drug and coated with a semi permeable membrane.

Validation of an externally oil-cooled 1 kWel HT-PEMFC stack operating at various experimental conditions

The performance of 1 kWel 48-cell HT-PEMFC at various experimental conditions is presented, particularly at several CO concentrations (up to 1.0%). Polarization curves measured at various anode (1.0-2.5) and cathode (1.6-4.0) stoichiometries; stack operating temperatures (120-160 o C) and gas pressures (up to 0.5 barg) arereported and analysed. The minimum gas stoichiometries of 1.25 and 2.0 were determined for the anode and cathode, respectively. The highest stack power density of 225 mW cm-2 was measured at 160 o C and 0.4 A cm-2. Operation at COconcentrations up to 1% was achieved, although a loss of performance of about 4% was observed for low CO concentrations. The operating temperature enhanced fuel cell performance and tolerance to CO, even when supplied with higher CO concentration in the anode feed gas.Web of Scienc

On the Formation of Collective Memories: The Role of a Dominant Narrator.

To test our hypothesis that conversations can contribute to the formation of collective memory, we asked participants to study stories and to recall them individually (pregroup recollection), then as a group (group recounting), and then once again individually (postgroup recollection). One way that postgroup collective memories can be formed under these circumstances is if unshared pregroup recollections in the group recounting influences others\u27 postgroup recollections. In the present research, we explored (using tests of recall and recognition) whether the presence of a dominant narrator can facilitate the emergence of unshared pregroup recollections in a group recounting and whether this emergence is associated with changes in postgroup recollections. We argue that the formation of a collective memory through conversation is not inevitable but is limited by cognitive factors, such as conditions for social contagion, and by situational factors, such as the presence of a narrator

Metal hydride hydrogen storage and compression systems for energy storage technologies

Along with a brief overview of literature data on energy storage technologies utilising hydrogen and metal hydrides, this article presents results of the related R&D activities carried out by the authors. The focus is put on proper selection of metal hydride materials on the basis of AB5- and AB2-type intermetallic compounds for hydrogen storage and compression applications, based on the analysis of PCT properties of the materials in systems with H2 gas. The article also presents features of integrated energy storage systems utilising metal hydride hydrogen storage and compression, as well as their metal hydride based components developed at IPCP and HySA Systems

The psychology of memory, extended cognition, and socially distributed remembering

This paper introduces a new, expanded range of relevant cognitive psychological research on collaborative recall and social memory to the philosophical debate on extended and distributed cognition. We start by examining the case for extended cognition based on the complementarity of inner and outer resources, by which neural, bodily, social, and environmental resources with disparate but complementary properties are integrated into hybrid cognitive systems, transforming or augmenting the nature of remembering or decision-making. Adams and Aizawa, noting this distinctive complementarity argument, say that they agree with it completely: but they describe it as “a non-revolutionary approach” which leaves “the cognitive psychology of memory as the study of processes that take place, essentially without exception, within nervous systems.” In response, we carve out, on distinct conceptual and empirical grounds, a rich middle ground between internalist forms of cognitivism and radical anti-cognitivism. Drawing both on extended cognition literature and on Sterelny’s account of the “scaffolded mind” (this issue), we develop a multidimensional framework for understanding varying relations between agents and external resources, both technological and social. On this basis we argue that, independent of any more “revolutionary” metaphysical claims about the partial constitution of cognitive processes by external resources, a thesis of scaffolded or distributed cognition can substantially influence or transform explanatory practice in cognitive science. Critics also cite various empirical results as evidence against the idea that remembering can extend beyond skull and skin. We respond with a more principled, representative survey of the scientific psychology of memory, focussing in particular on robust recent empirical traditions for the study of collaborative recall and transactive social memory. We describe our own empirical research on socially distributed remembering, aimed at identifying conditions for mnemonic emergence in collaborative groups. Philosophical debates about extended, embedded, and distributed cognition can thus make richer, mutually beneficial contact with independently motivated research programs in the cognitive psychology of memory.40 page(s
