This paper aims to present the components' characterization and condition assessment of an important deteriorated Mamluk-illuminated paper manuscript housed in Al-Azhar Library, Egypt.

Different analytical techniques used in this study were the portable digital optical microscope, stereomicroscope, scanning electron microscope with EDX (SEM.EDX), portable X-ray fluorescence (pXRF), X-ray diffraction (XRD), pH measurement and Fourier transform infrared spectroscopy (FTIR).

The results obtained by different microscopes showed that the gilding in the surface of illuminated paper sheets was performed with gold leaves. Additionally, these microscopes revealed that the illuminated paper manuscript has different aspects of deterioration such as adhered dirt, staining, some micro-cracks, cracks and detachment of some parts in some illuminated areas. The results of elemental analysis by EDX, portable XRF and XRD analysis showed that the orange red pigment is red lead (Pb₃O₄), blue pigment is azurite (2CuCo₃.Cu (OH)₂), and the gold layer is has consisted of brass alloy (Cu-Zn) with a small amount of gold element (Au). The pH measurement stated that the historical paper in the acidity level. The ATR-FTIR analysis also revealed the oxidation of cellulose. Moreover, it was found from ATR-FTIR that Arabic gum was used as a binder for the pigments.

This study presents the important results of analytical methods used for condition assessment and identification of the components of an important Mamluk-illuminated paper manuscript, where these results referred that the studied paper manuscript had different aspects of deterioration. The conservation steps either conservation treatment or preventive conservation are urgently needed in future studies.

Marischal College Buildings, i.e. the second and more modern portion of the University are situated in Broad Street; Aberdeen. Their site is the same as that which they originally occupied, viz.: the conventual buildings and grounds of the Grey Friars or Franciscan Monastery, which accounts for the proximity of the Grey‐friar's Church within what is now the College Quadrangle. The Library of this Quadrangle, entering the central door of the Mitchell Tower, thus reaching the vestibule in which the famous stone (the only remnant of the original College Buildings in the new Town) with the inscription passing up the flight of stairs leading to the Picture Gallery and Mitchell —“they haif said : quhat say they: let them say,” is to be seen, thence Hall—the latter being a piece of architectural excellence well worth a visit. The library door is on the left of the landing at the head of the stairs already mentioned, and the books contained in it belong to the Departments of Agriculture, Law, Medicine, and Natural Science.

Optimization of the process parameters remains a challenging task in thermosonic wire bonding due to relatively poor understanding of the bonding mechanism. The purpose of this paper is to understand initial bond formation in thermosonic gold wire bonding on aluminium metallization pads and the effect of bonding time on the initiation of bonding.

A gold wire (20 μm diameter/99.99 per cent wt%) was bonded to aluminium metallization pads (1 μm thick) on a silicon chip using a commercial ball/wedge automatic bonder. Bonding parameters were selected specifically to produce underdeveloped ball bonds so that ball lift‐off occurred during looping process. The lift‐off footprints on the aluminium metallization pads and their evolution were carried out using optical microscopy and scanning electron microscopy. A model is proposed to elaborate the effect of bonding time on initiation of bonding.

The obtained results showed that metallurgical bonding initiated at the peripheral areas of the contact area situated along the direction of ultrasonic vibration. Those areas extended inwards with bonding time, eventually covering the entire contact area.

This paper describes how bond initiation and its evolution in thermosonic gold wire bonding on aluminium metallization is ascertained by observing lift‐off footprints. The understanding of bonding mechanism benefits the optimization of process parameters and improvement of bondability in thermosonic wire bonding.

In Austria the 1930s constituted the final period of success and failure of the Austrian school, ending with its emigration to the United States. This chapter focuses on this period, when the Austrian economy was hardest hit by the Great Depression, and it examines the ways and means by which the Austrian economists attempted to influence economic policy. In particular, from 1932 to 1934 in a concerted effort Austrian economists like Ludwig Mises, Fritz Machlup, and especially Oskar Morgenstern tried to “educate” the Austrian public and policy-makers in the benefits of a liberal approach towards the crisis. This effort included the advocacy of the policies typically associated with the gold standard, that is, stable money, balanced budgets, the absence of exchange restrictions, and free trade. In the actual situation the outcome of these endeavors was futile, if not harmful, insofar as indeed Austrian economic policy slowly converted to the implied deflationary stance of monetary and fiscal policy. Yet, under the regime of the so-called corporate state the necessary complement of such policies, namely the flexibility of prices and the furthering of competition, could not be accomplished. This eventual failure of the liberal cause may be ascribed to the fact that it had to rely on shifting coalitions and fragile personal relations, which in the end turned out too weak for sustaining the policies envisioned by the Austrian economists.

You may be surprised to discover that millions of dollars in revenue are sitting, undiscovered, inside your own organization. Follow the authors as they walk you through different areas of your business to discover the untapped potential of “forgotten” intangible assets that may already exist, including patents, trademarks, licensing arrangements, employee know‐how, infringement protection plans and much more. Learn how to manage these assets to their fullest potential by creating an Intellectual Asset Management Portfolio (I‐AMP). The authors reveal their own five‐step process and then present three case studies (an energy company, a high‐tech manufacturer and a telecom company), which illustrate the remarkable increases in revenue generated by this program. In one case, $1 billion was shifted from the expenditure to the revenue side of the ledger!

The equation of unified knowledge says that S = f (A,P) which means that the practical solution to a given problem is a function of the existing, empirical, actual realities and the future, potential, best possible conditions of general stable equilibrium which both pure and practical reason, exhaustive in the Kantian sense, show as being within the realm of potential realities beyond any doubt. The first classical revolution in economic thinking, included in factor “P” of the equation, conceived the economic and financial problems in terms of a model of ideal conditions of stable equilibrium but neglected the full consideration of the existing, actual conditions. That is the main reason why, in the end, it failed. The second modern revolution, included in factor “A” of the equation, conceived the economic and financial problems in terms of the existing, actual conditions, usually in disequilibrium or unstable equilibrium (in case of stagnation) and neglected the sense of right direction expressed in factor “P” or the realization of general, stable equilibrium. That is the main reason why the modern revolution failed in the past and is failing in front of our eyes in the present. The equation of unified knowledge, perceived as a sui generis synthesis between classical and modern thinking has been applied rigorously and systematically in writing the enclosed American‐British economic, monetary, financial and social stabilization plans. In the final analysis, a new economic philosophy, based on a synthesis between classical and modern thinking, called here the new economics of unified knowledge, is applied to solve the malaise of the twentieth century which resulted from a confusion between thinking in terms of stable equilibrium on the one hand and disequilibrium or unstable equilibrium on the other.

This chapter investigates the nature of the transformation of macroeconomics by focusing on the impact of the Great Depression on economic doctrines. There is no doubt that the Great Depression exerted an enormous influence on economic thought, but the exact nature of its impact should be examined more carefully. In this chapter, I examine the transformation from a perspective which emphasizes the interaction between economic ideas and economic events, and the interaction between theory and policy rather than the development of economic theory. More specifically, I examine the evolution of what became known as macroeconomics after the Depression in terms of an ongoing debate among the “stabilizers” and their critics. I further suggest using four perspectives, or schools of thought, as measures to locate the evolution and transformation; the gold standard mentality, liquidationism, the Treasury view, and the real-bills doctrine. By highlighting these four economic ideas, I argue that what happened during the Great Depression was the retreat of the gold standard mentality, the complete demise of liquidationism and the Treasury view, and the strange survival of the real-bills doctrine. Each of those transformations happened not in response to internal debates in the discipline, but in response to government policies and real-world events.

I. The Gendarmerie: Historical Background The Gendarmerie is the senior unit of the French Armed Forces. It is, however, difficult to give a precise date to its creation. What can be asserted is that as early as the Eleventh Century special units existed under the sénéchal (seneschal), an official of the King's household who was entrusted with the administration of military justice and the command of the army. The seneschal's assistants were armed men known as sergents d'armes (sergeants at arms). In time, the office of the seneschal was replaced by that of the connétable (constable) who was originally the head groom of the King's stables, but who became the principal officer of the early French kings before rising to become commander‐in‐chief of the army in 1218. The connétable's second in command was the maréchal (marshal). Eventually, the number of marshals grew and they were empowered to administer justice among the soldiery and the camp followers in wartime, a task which fully absorbed them throughout the Hundred Years War (1337–1453). The corps of marshals was then known as the maréchaussée (marshalcy) and its members as sergeants and provosts. One of the provosts, Le Gallois de Fougières, was killed at Agincourt in 1415; his ashes were transferred to the national memorial to the Gendarmerie, which was erected at Versailles in 1946.

WE give space this month to practical library binders to describe their work as they see it. Such an arrangement will commend itself to our readers, we hope, as there is no more present question with the librarian, and especially the public librarian. Since the war the quality of book‐papers has been such that binding has become the most formidable item in his annual budget except salaries and new book purchase. The cases in which publishers issue their books used to give about 60 issues before re‐binding was necessary; now they rarely give half that number. Binders have shown considerable ingenuity in discovering new methods of sewing, lining and strengthening, to meet the perishable qualities of the paper. Whether they have succeeded or not librarians may judge. The ideal binding for a reference book is an imperishable one; for a lending library book one that lasts in pleasant complexion just as long as the paper holds together. Anything less or more appears to be uneconomical.
