Many species of hibernating mammals rely on hoarded food rather than body fat to support winter energy requirements. Here, we evaluate whether the associated ingestive and digestive requirements reduce the benefits that food-storing hibernators can accrue from torpor. Using a simple model, we predict (1) that digestive efficiency could either increase or decrease with increased use of torpor, d...

This paper is concerned with storing XML data in a native repository suitable for querying with modern languages such as XPath or XQuery. It contains a description of the experimental database, SXQ-DB, its basic principles and system internals. Some of query evaluation techniques and problems related with those methods in relation to amount of stored information are mentioned.

This paper describes a simple approach to the fatigue testing of prosthetic feet. A fatigue testing machine for prosthetic feet was designed as part of the programme to develop an energy storing prosthetic foot (ESPF). The fatigue tester does not simulate the loading pattern on the foot during normal walking. However, cyclic vertical loads are applied to the heel and forefoot during heel-strike...

Memory forensic is important in digital investigation. The forensic is based on the data stored in physical memory that involve memory management and processing time. However, the current forensic tools do not consider the efficiency in terms of storage management and the processing time. This paper shows the high redundancy of data found in the physical memory that cause inefficiency in proces...

The lamprey heart contains characteristic catecholamine-storing cells in both the atrium and the ventricle. Sufficient circumstantial evidence is available indicating that catecholamines together with protein carbohydrate complexes are contained in these cells within the membrane bound cytoplasmic granules. If the "recepto-secretory function" and "neuroectodermal origin" of these cells are prov...

Gaunt coefficients express angular momentum conservation rules. They are therefore required in the combination of atomic orbitals. In this case, the angular factors are real spherical harmonics and the Gaunt coefficients appear when their products are linearized. The Gaunt coefficients may be pre-calculated and stored. This work describes new index functions for storing and retrieving the requi...

Food storing is seasonal in birds like chickadees, nuthatches and jays, occurring at high levels in fall and winter and low levels in spring and summer. Memory for cache sites is hippocampus dependent in chickadees and both the recruitment of new neurons into the hippocampus and the total size of the hippocampus change seasonally. Unlike seasonal change in the vocal control nuclei of songbirds,...

Among the passerine birds, species that store food have an enlarged hippocampal region (dorso-medial cortex), relative to brain and body size, when compared with the non-storers. The volume of one of the major afferent-efferent pathways (the septo-hippocampal pathway) is also greater in food storing species. This specialization of brain structure is discussed in relation to behavioural studies ...

Fat-storing cells in the liver of an adult Schneider's skink were investigated by means of transmission electron microscopy. The fat-storing cells were localized in the perisinusoidal space or in the hepatic "recessus". They revealed a single cilium originating from one of the paired centrioles and projecting into the perisinusoidal space. The functional significance of a single cilium in the f...
