Abstract:

Volumetric heat transfer coefficients for direct-contact heat exchange between air and molten nitrate salt have been measured as a function of air and salt flow rates at 350° C salt inlet temperature. Using these heat transfer data for a packed column-type heat exchanger, an economic analysis was used to compare direct-contact heat exchange with conventional finned-tube heat exchangers. High volumetric rates of heat transfer (2000–3000 W/m3 °C) and flexibility in choice of materials of construction allow one to realize significant economic benefits by using direct-contact heat exchange in this

Abstract:

The nature of 8th century Corinthian contact with sites in Phokis, Ithaka and Epirus is discussed, and archaeological evidence from these areas re-examined. It is suggested that early exchange activity is more complex than has hitherto been recognised, and should be regarded as independent of subsequent colonisation. A change in the pattern of contacts is distinguished from c. 725, and it is argued that Corinthian western trade was redirected in the wake of colonisation. Possible motivation for contact is assessed, and it is suggested that metal, especially copper, may have been the main commo

Abstract:

The region of physical feasibility of heat exchange systems in the space of their thermodynamic indicators (heat load, dissipation, and thermal conductivity) is constructed in this work. Criteria of thermodynamic perfection for typical two-flow cells are calculated. A condition of thermodynamic equivalence of heat exchange systems is given, and an algorithm for constructing a multiflow system equivalent to a two-flow heat exchanger is proposed. The cases of variable heat capacity, change of the phase state, and different flow hydrodynamics are considered. The constraints on the temperatures of

Abstract:

Abstract When two insulating, neutral materials are contacted and separated, they exchange electrical charge1. Experiments have long suggested that this ‘contact electrification’ is transitive, with different materials ordering into ‘triboelectric series’ based on the sign of charge acquired2. At the same time, the effect is plagued by unpredictability, preventing consensus on the mechanism and casting doubt on the rhyme and reason that series imply3. Here we expose an unanticipated connection between the unpredictability and order in contact electrification: nominally identical materials init

Membrane contact sites (MCS) are critical for cellular functions of eukaryotes, as they enable communication and exchange between organelles. Research over the last decade unravelled the function and composition of MCS between a variety of organelles including mitochondria, ER, plasma membrane, lysosomes, lipid droplets, peroxisome and endosome, to name a few. In fact, MCS are found between any pair of organelles studied to date, with common functions including lipid exchange, calcium signalling and organelle positioning in the cell.

Energy from hot gas discharge streams can be recovered by transfer directly to a coolant liquid in one of several available gas-liquid contacting devices. The design of the device is central to the theme of this paper, and experimental work has verified that the analogy between heat transfer and mass transfer can be used for design purposes. This enables the large amount of available mass transfer data for spray, packed, and tray columns to be used for heat transfer calculations. Recommended methods for designing the several types of gas-liquid contacting device are summarized.

Temporally precise vocal exchanges, termed “antiphonal calling”, might allow pair or group members to maintain social contact with greater efficiency than when calling independently. The white-winged vampire bat ( Diaemus youngi (Jentink, 1893)) is a group-living species that produces social calls in antiphonal exchanges. Because white-winged vampire bats can use social calls to discriminate conspecifics, we suspect that one function of these vocal exchanges is to allow group members to know who is where. Here, we tested the prediction that antiphonal calling by groups of white-winged vampire

Abstract:

It has been shown by the anomalous Hall effect method that upon contact of layers of iron group metal (Ni) and REM oxide (Gd2O3) nanosized films, an increase by 15–35 % in the magnetization of the ferromagnetic metal is observed. Such an increase does not require energy consumption and the use of amplifying equipment, is very promising for nanotechnology. The enhancement of magnetization is due to the appearance in the contact region of the exchange f–d interaction between atoms with empty d– and f–electron shells that are parts of the layers. The exchange interaction stimulates the ordering o

Abstract:

The paper presents studies on the use of nanomodified materials with phase transitions. The rmostable heat exchange devices based on materials modified with carbon nanotubes allowing to control thermal contact have been developed. It is established that through a controlled thermal contact it is possible to provide a heat flux of up to 100 [kW·m-2 ]. The application of heat-resistance storage material in technical devices such as self-rescuers is justified. The efficiency of thermal control is established, since the temperature after the heat exchanger is reduced to 40 ° C at an incoming tempe

Abstract:

Lipid transport between membranes within cells involves vesicle and protein carriers, but as agents of nonvesicular lipid transfer, the role of membrane contact sites has received increasing attention. As zones for lipid metabolism and exchange, various membrane contact sites mediate direct associations between different organelles. In particular, membrane contact sites linking the plasma membrane (PM) and the endoplasmic reticulum (ER) represent important regulators of lipid and ion transfer. In yeast, cortical ER is stapled to the PM through membrane-tethering proteins, which establish a dir

Abstract:

The text deals with the question of the influence of international exchange programmes on reducing ethnic prejudices in their participants. Apart from a brief introduction into the issue of reducing prejudice, it comprises 392 free responses of Czech respondents, predominantly students, who have filled out an online survey as part of the project Intergroup Attitudes and Intergroup Contact in Central Europe. The participants gave accounts of their real contacts with Polish people, oftentimes within the framework of international exchange programmes, Erasmus in particular. Based on the compariso
