Southern Africa has provided much information concerning the cultural, technological and cognitive evolution of Homo sapiens. As indications of cognitive complexity that become prevalent during the Middle Stone Age, abstract and figurative art present explicit evidence for modern and symbolic human behavioural capacity. The only examples of African figurative art securely dated to the Late Pleistocene comprise seven stone plaques from Apollo 11 Cave in the Huns Mountains, Karas region, Namibia. These were recovered by Wendt in 1969 and 1972 from levels dated to c. 30 000 years ago. Given the cultural and evolutionary significance of these artefacts, the objective of this report is to make available high resolution actual-size colour and digitally enhanced photographs of these unique examples of early art mobilier. Chemical analysis of the plaques and the pigments that compose the imagery is ongoing and will be presented in a forthcoming publication.

By similar methods as Calderón [1] and Stein [10], we prove some restriction theorems on weighted potential spaces when the weight satisfies Muckenhoupt's Ap condition. We then construct potential spaces of mixed norm and find that mixed norm potential spaces are indeed a natural object in the study of restriction theorems. With the help of mixed norm spaces, we obtain a better version of restriction theorem.

Statistical analysis of dated documents from Sneferu's reign implies that the cattle count took place more often annually than biennially. Thus the ‘twenty-fourth occasion of the (cattle) count’, which is the highest date yet known for Sneferu and which exceeds the 24 years allotted him in the Turin Canon, cannot be equivalent to 45 regnal years but rather to about 30. On the basis of the dates preserved on blocks from the king's Red Pyramid, a model can be constructed to demonstrate that about eleven years were required for its construction. This period accords well with a reign of about 30 years.

The treatment of "time" is discussed as both a syntactic & a grammatical category by the Indian grammatical tradition. Some objections raised by the Buddhists to the views of Bhartrhari & the Paniniyas are described & answered. Among these are the validity of the concept of present time. This contrasts with the Buddhist view of time as moments in a flow, with no permanence or persistence. 52 References. Adapted from the source document

Heavy oil and oil sands deposits constitute an important resource, with in-place estimates varying between 600 × 109and 980 × 109m3. These deposits are mostly concentrated in Canada, the US and Venezuela. The gradual depletion of conventional oil reserves is leading to a greater interest in heavy oil *** paper presents on overview of heavy oil characteristics, worldwide deposits and recovery methods, with special emphasis on the heavy oils and oil sands of Canada. Thermal recovery techniques such as cyclic steam stimulation, steamflooding and in-situ combustion have been generally more successful than non-thermal methods. The principal thermal recovery processes are discussed in detail. Reservoir characteristics influencing the applicability of these processes are mentioned, and possible operational problems are *** of the Canadian heavy oils and oil sands deposits occur in the provinces of Alberta and Saskatchewan. Selected recovery projects currently in operation are described, outlining modifications to the basic process, problems encountered and range of success.

The survey of Memphis continued its excavation at Kôm Rabî'a in the south-west quadrant of the Memphite ruin field, finding evidence of terracing up to the north and west and a substantial rebuilding of the central property not earlier than the reign of Tutankhamun. The Epigraphic Section began its survey of the Ptah temple with a study of the colossal limestone statue of Ramesses II at the south gate. Work proceeded at Saqqâra on publication of the Mother of Apis stelae from the Sacred Animal Necropolis, and on the ceramic collection from the Anubieion.
