Abstract As political questions behind Pakistan's emergence distilled themselves into aesthetic questions of how to represent a country without a past, the debate erupted through the spatial practices determining the form and architectural character of the nation's two capitols. President Ayub Khan's two ambitious urban projects—Islamabad, the new capital city of Pakistan and Ayub-Nagar (renamed Sher-e-Bangla Nagar), and a second capitol complex in East Pakistan—brought together local and foreign stakeholders with differing interpretations of the idea of “Pakistan.” A significant part of each project's documentation lies far from its site—with the University of Pennsylvania, in the personal papers of Louis Kahn, the US-based architect whose firm designed each. This collection—a vital resource to consider the expanded meaning of architecture, not as an end product, but as a process—emerges as a crucial body of evidence for the evolution of multiple narratives of the political idea of Pakistan. The design process, as documented in sketches, architectural drawings, reports, and correspondence, reflects the frictions created from unfulfilled expectations and the subsequent disillusionment of vested interest groups, shedding new light on constructions of the past and future in postindependence Pakistan.

The City

During the survey campaign of the TOVIVA research project “Torres de vigía y defensa del litoral valenciano. Generación de metadatos y modelos 3D para su interpretación y efectiva puesta en valor,” many of these towers have been digitally surveyed using 3D laser scanner, and terrestrial and aerial photogrammetry. The survey campaign took place in April 2015 and after gathering the data, a phase of elaboration has successfully produced the architectural drawings of plans, elevations and sections. A part of this documentation has been collected on the poster "When an isolated building becomes a guideline for the urban pattern. The case of “Torrenostra” in Torreblanca, Castellón, Spain", by T. G. Piqueras S. Giraudeau and A. Leonardi in 2015. In this case we want to present an evolution of the work, aiming to reconstruct the original landscape around it. Although today the tower is surrounded by other buildings on both sides, the situation was different in the past, when the tower was isolated on the coast. Rediscovering the original landscape of the city could be a topic of interest and discussion in the Museum of the Territory of Torreblanca. This could take place inside the tower and explain to visitors the history of the territory and its evolution, involving the structure of the tower itself, changing its shape and value. The 3D reconstruction, both digital and tangible, is also a good way to involve children and adults alike, adding a special value to a historical building.

A continuum survey of the galactic-centre region has been carried out at Parkes at 20 cm wavelength over the areal11= 355° to 5°,b11= -3° to +3° (Kerr and Sinclair 1966, 1967). This is a larger region than has been covered in such surveys in the past. The observations were done as declination scans.

Origin Of The Moon

During the last 10 years, the writer has presented evidence indicating that the Moon was captured by the Earth and that the large collisions with its surface occurred within a surprisingly short period of time. These observations have been a continuous preoccupation during the past years and some explanation that seemed physically possible and reasonably probable has been sought.

History Of

It is generally accepted that history is an element of culture and the historian a member of society, thus, in Croce's aphorism, that the only true history is contemporary history. It follows from this that when there occur great changes in the contemporary scene, there must also be great changes in historiography, that the vision not merely of the present but also of the past must change.

It is perhaps one of the most important characteristics of the past decade in astronomy that the evolution of some major classes of astronomical objects has become accessible to detailed research. The theory of the evolution of individual stars has developed into a substantial body of quantitative investigations. The evolution of galaxies, particularly of our own, has clearly become a subject for serious research. Even the history of the solar system, this close-by intriguing puzzle, may soon make the transition from being a subject of speculation to being a subject of detailed study in view of the fast flow of new data obtained with new techniques, including space-craft.

During the past several years, a systematic search for novae in the Magellanic Clouds has been carried out at Cerro Tololo Inter-American Observatory. The Curtis Schmidt telescope, on loan to CTIO from the University of Michigan is used to obtain plates every two weeks during the observing season. An objective prism is used on the telescope. This provides additional low-dispersion spectroscopic information when a nova is discovered. The plates cover an area of 5°x5°. One plate is sufficient to cover the Small Magellanic Cloud and four are taken of the Large Magellanic Cloud with an overlap so that the central bar is included on each plate. The methods used in the search have been described by Graham and Araya (1971). In the CTIO survey, 8 novae have been discovered in the Large Cloud but none in the Small Cloud. The survey was not carried out in 1974 or 1976. During 1974, one nova was discovered in the Small Cloud by MacConnell and Sanduleak (1974).

Immunoferritin localization of intracellular antigens in positively stained frozen sections

Definition Of

During the past investigations of immunoferritin localization of intracellular antigens in ultrathin frozen sections, we found that the degree of negative staining required to delineate u1trastructural details was often too dense for the recognition of ferritin particles. The quality of positive staining of ultrathin frozen sections, on the other hand, has generally been far inferior to that attainable in conventional plastic embedded sections, particularly in the definition of membranes. As we discussed before, a main cause of this difficulty seemed to be the vulnerability of frozen sections to the damaging effects of air-water surface tension at the time of drying of the sections.Indeed, we found that the quality of positive staining is greatly improved when positively stained frozen sections are protected against the effects of surface tension by embedding them in thin layers of mechanically stable materials at the time of drying (unpublished).

Studies of the nature of a surface, either metallic or nonmetallic, in the past, have been limited to the instrumentation available for these measurements. In the past, optical microscopy, replica transmission electron microscopy, electron or X-ray diffraction and optical or X-ray spectroscopy have provided the means of surface characterization. Actually, some of these techniques are not purely surface; the depth of penetration may be a few thousands of an inch. Within the last five years, instrumentation has been made available which now makes it practical for use to study the outer few 100A of layers and characterize it completely from a chemical, physical, and crystallographic standpoint. The scanning electron microscope (SEM) provides a means of viewing the surface of a material in situ to magnifications as high as 250,000X.

Topographical Relief

The structure of insect salivary glands has been extensively investigated during the past decade; however, none have attempted scanning electron microscopy (SEM) in ultrastructural examinations of these secretory organs. This study correlates fine structure by means of SEM cryofractography with that of thin-sectioned epoxy embedded material observed by means of transmission electron microscopy (TEM).Salivary glands of Gromphadorhina portentosa were excised and immediately submerged in cold (4°C) paraformaldehyde-glutaraldehyde fixative1 for 2 hr, washed and post-fixed in 1 per cent 0s04 in phosphosphate buffer (4°C for 2 hr). After ethanolic dehydration half of the samples were embedded in Epon 812 for TEM and half cryofractured and subsequently critical point dried for SEM. Dried specimens were mounted on aluminum stubs and coated with approximately 150 Å of gold in a cold sputtering apparatus.Figure 1 shows a cryofractured plane through a salivary acinus revealing topographical relief of secretory vesicles.
