Core Production

The ongoing archaeological survey and excavations in Faid area north of Saudi Arabia uncovered remains of a large early Islamic settlement. During excavation of season 2019 Paleolithic artefacts discovered in the building foundations indicated of Paleolithic site buried partially by the settlement ruins. An archaeological exploration carried out in the area around the site during March 2020, where are three Paleolithic sites documented Faid 1 – Faid 3). In February 2021 archaeological survey extended to the east and west, where are new four Paleolithic sites have been discovered (Faid 4 – Faid 7). The archaeological sites represented two main Paleolithic traditions, Acheulean identified from the bifaces and Middle Paleolithic horizon represented by prepared core production and bifacial point referable to Levallois meth. Faid 2 is a unique Acheulean site, where a systematic survey shows agglomeration of LCTs covered an area of 15 hectares. Bifaces (handaxes and cleavers) are the most conspicuous artefacts characteristics. Thus the archaeological sites localities and lithics technocomplex has direct relevance for assessing hominin dispersal routes along Arabia to Eurasia.

Made In

I should like to give you a very condensed progress report on some spectrophotometric measurements of objective-prism spectra made in collaboration with H. Leicher at Bonn. The procedure used is almost completely automatic. The measurements are made with the help of a semi-automatic fully digitized registering microphotometer constructed by Hög-Hamburg. The reductions are carried out with the aid of a number of interconnected programmes written for the computer IBM 7090, beginning with the output of the photometer in the form of punched cards and ending with the printing-out of the final two-dimensional classifications.

Centre Region

In the course of several 21-cm observing programmes being carried out by the Leiden Observatory with the 25-meter telescope at Dwingeloo, a fairly complete, though inhomogeneous, survey of the regionl11= 0° to 66° at low galactic latitudes is becoming available. The essential data on this survey are presented in Table 1. Oort (1967) has given a preliminary report on the first and third investigations. The third is discussed briefly by Kerr in his introductory lecture on the galactic centre region (Paper 42). Burton (1966) has published provisional results of the fifth investigation, and I have discussed the sixth in Paper 19. All of the observations listed in the table have been completed, but we plan to extend investigation 3 to a much finer grid of positions.

Drill Holes

The fabrication of the aluminum bridge test vehicle for use in the crystallographic studies of electromigration involves several photolithographic processes, some common, while others quite unique. It is most important to start with a clean wafer of known orientation. The wafers used are 7 mil thick boron doped silicon. The diameter of the wafer is 1.5 inches with a resistivity of 10-20 ohm-cm. The crystallographic orientation is (111).Initial attempts were made to both drill and laser holes in the silicon wafers then back fill with photoresist or mounting wax. A diamond tipped dentist burr was used to successfully drill holes in the wafer. This proved unacceptable in that the perimeter of the hole was cracked and chipped. Additionally, the minimum size hole realizable was > 300 μm. The drilled holes could not be arrayed on the wafer to any extent because the wafer would not stand up to the stress of multiple drilling.
