Past: In 1960 Thornley published the first description of SEM studies carried out at low beam voltage (LVSEM, 1-5 kV). The aim was to reduce charging on insulators but increased contrast and difficulties with low beam current and frozen biological specimens were also noted. These disadvantages prevented widespread use of LVSEM except by a few enthusiasts such as Boyde. An exception was its use in connection with studies in which biological specimens were dissected in the SEM as this process destroyed the conducting films and produced charging unless LVSEM was used.In the 1980’s field emission (FE) SEM’s came into more common use. The high brightness and smaller energy spread characteristic of the FE-SEM’s greatly reduced the practical resolution penalty associated with LVSEM and the number of investigators taking advantage of the technique rapidly expanded; led by those studying semiconductors. In semiconductor research, the SEM is used to measure the line-width of the deposited metal conductors and of the features of the photo-resist used to form them. In addition, the SEM is used to measure the surface potentials of operating circuits with sub-micrometer resolution and on pico-second time scales. Because high beam voltages destroy semiconductors by injecting fixed charges into silicon oxide insulators, these studies must be performed using LVSEM where the beam does not penetrate so far.

This article analyzes the formation of the Russian institutional matrix with regard to its previous development, but in line with the laws of economic evolution. The structure and development of an razdatok-type institutional matrix on three institutional cycles is considered. It is shown that in transformationphases the market institutional matrix masking the quasi-market is used. The author concludes that system crises could be overcome due to the mutual substitution of the two types of institutional matrices, and the cyclic path of Russias development became a consequence of that. The paper claims that the current institutional matrix will provide transition to a new level of high-quality growth only in case of synthesis of market and razdatok mechanisms.

This part describes the agent-based and computational model for Agent_Zero and demonstrates its capacity for generative minimalism. It first explains the replicability of the model before offering an interpretation of the model by imagining a guerilla war like Vietnam, Afghanistan, or Iraq, where events transpire on a 2-D population of contiguous yellow patches. Each patch is occupied by a single stationary indigenous agent, which has two possible states: inactive and active. The discussion then turns to Agent_Zero's affective component and an elementary type of bounded rationality, as well as its social component, with particular emphasis on disposition, action, and pseudocode. Computational parables are then presented, including a parable relating to the slaughter of innocents through dispositional contagion. This part also shows how the model can capture three spatially explicit examples in which affect and probability change on different time scales.

History Of

The history of the formation of South Africa as a single state is closely intertwined with events of international scale, which have accordingly influenced the definition and development of the main characteristics of the foreign policy of the emerging state. The Anglo-Boer wars and a number of other political and economic events led to the creation of the Union of South Africa under the protectorate of the British Empire in 1910. The political and economic evolution of the Union of South Africa has some specific features arising from specific historical conditions. The colonization of South Africa took place primarily due to the relocation of Dutch and English people who were mainly engaged in business activities (trade, mining, agriculture, etc.). Connected by many economic and financial threads with the elite of the countries from which the settlers left, the local elite began to develop production in the region at an accelerated pace. South Africa’s favorable climate and natural resources have made it a hub for foreign and local capital throughout the African continent. The geostrategic position is of particular importance for foreign policy in South Africa, which in many ways predetermined a great interest and was one of the fundamental factors of international involvement in the development of the region. The role of Jan Smuts, who served as Prime Minister of the Union of South Africa from 1919 to 1924 and from 1939 to 1948, was particularly prominent in the implementation of the foreign and domestic policy of the Union of South Africa in the focus period of this study. The main purpose of this article is to study the process of forming the mechanisms of the foreign policy of the Union of South Africa and the development of its diplomatic network in the period from 1910 to 1948.
