Airborne Electromagnetics

The art of prospecting by electromagnetic (EM) methods has progressed so rapidly in the last decade that it would seem timely for the publication of a review on this field of activity. Airborne EM surveys have been conducted on a world‐wide basis for quite a number of years, and they are now accepted as a standard and proven exploration tool. Unlike, however, the field of airborne magnetics which has received a great deal of attention in publications in many technical journals, the airborne EM method has scarecely been touched upon, publication‐wise. A few papers have been presented in the past on specific types of EM prospecting instruments and methods, but to the writer’s knowledge, no attempt as yet has been made to incorporate all the various techniques and EM instruments in one article. This review is therefore primarily an attempt to set down for the reader a short history of airborne EM development, along with some details on each of the different types of EM systems or instruments which have flown in the past or are presently flying today.

Abstract STEREOTACTIC RADIOSURGERY IS the single-session, precise delivery of a therapeutically effective radiation dose to an imaging-defined target. Conceived and developed during the past 5 decades, stereotactic radiosurgery has involved significant advances, which have improved patient outcomes and made it a critical component of modern neurosurgical practice and training. In this article, a short history of stereotactic surgery and radiosurgery are presented, and radiosurgery is contrasted to radiation therapy. Adherence to accepted, descriptive terms in defining stereotactic radiosurgery and radiation therapy permits a clear distinction among the results of the different radiation delivery techniques for patients, physicians, and other interested parties.

Automatic speech processing (ASP) is understood as covering word recognition, the processing of higher linguistic components (syntax, semantics, and pragmatics), and the processing of computational paralinguistics (CP), which deals with speaker states and traits. This chapter attempts to track the role of prosody in ASP from the word level up to CP. A short history of the field from 1980 to 2020 distinguishes the early years (until 2000)—when the prosodic contribution to the modelling of linguistic phenomena, such as accents, boundaries, syntax, semantics, and dialogue acts, was the focus—from the later years, when the focus shifted to paralinguistics; prosody ceased to be visible. Different types of predictor variables are addressed, among them high-performance power features as well as leverage features, which can also be employed in teaching and therapy.

This paper presents a short history of Polish formations protecting the governing bodies of the state, starting from the moment Poland regained independence at the end of the twentieth century. The considerations are presented against the rules and principles of the functioning of the state security system, with particular emphasis on the control subsystem. This paper demonstrates the need to research attitudes to safety in the past, in order to develop and apply effective contemporary solutions. The considerations contained in it also concern the existing threats to the management of state organs. They may contribute to further discussions on the purpose and rules of operation of the formation which is supposed to protect the most important people in the state.

The kingdom of Benin has the reputation of being one of the most important examples for a king-oriented state-formation in sub-Saharian Africa. In the past few decades much research has appeared on the early history of this kingdom, the origin of its kingship, and the time of the early Ogiso kings, who are considered by many historians as the autochthonous founders of Benin kingship around 900. These Ogiso rulers are assumed to have been replaced between the eleventh and thirteenth centuries by kings of the later Oba dynasty, which supposedly descends from the Yoruba town of Ife and which continues in office at the present.The abundance of literature on the early history of the Benin kingdom often hides the fact that, apart from sporadic—and for the most part isolated—reports from travelers, a few archeological accounts, and some vaguely dated objects from Benin, the reconstruction of the early history of Benin is based almost exclusively on the data of the Bini local historian Jacob Egharevba, who published prolifically on Benin history and culture from 1930 to 1970. The most famous of his works is the Short History of Benin—a small publication, where the author deals with the history of the kingdom from its origins until the twentieth century.

Abstract At present, physicians and surgeons treating thyroid disorders can rely on highly accurate and precise investigations, modern equipment, and state of the art operating theater to achieve optimum results; however, this was not the case at the beginning of the treatment of thyroid diseases centuries ago. We present a short history of the treatment and understanding of thyroid diseases in the past few decades. Also we present the contributions of the important surgeons who tried to perfect the treatment of thyroid diseases, including surgery, thus making modern day management easier.

A short history of nitrocellulose (NC) use in propellants is discussed. The advantages and disadvantages of NC as a semi-synthetic component of powders and rocket propellants are presented. Based on the conventional classification of propellants, the options of eliminating nitrocellulose in different types of powders and rocket propellants are discussed in detail. The analysis shows that in the foreseeable future, the elimination of NC in single-base and double-base propellants is highly unlikely. The observed trends in triple-base propellant development also does not show any tendencies in the elimination of NC, only the replacement of nitroguanidine with cyclic nitroamines. However, the elimination of NC in LOVA composite propellants is probable. Synthetic, rubber-based solid composite rocket propellants, with ammonium perchlorate as the oxidizer, are the only ones not dependent on NC.

Since the fall of communism in 1989, Romanian citizens have changed dramatically, along with Romanian electronic media, which have transformed themselves from a one-party-controlled institution to a plethora of commercial broadcasters. By focusing on this era of dramatic transition, this thesis argues that documentary films have provided Romanians with the tools needed to deal with the past critically. More specifically, the intent of this thesis is to analyze how documentary films do the work of selecting, recollecting, and re-presenting narratives of the past, and to demonstrate that editorial choices resonate with wider social needs. The scope is limited to a short history of the documentary genre, focusing on a detailed analysis of two post-communist documentaries: Memorial of Pain ('Memorialul durerii', 1991), by TV producer Lucia Hossu-Longin and The Great Communist Bank Robbery ("Marele jaf comunist', 2004), by Alexandru Solomon. Ultimately, the thesis traces the ways in which trauma, shame, and amnesia also influence the shaping of both documentaries and identities.

Physical Stimuli

Psychophysics is the oldest branch of experimental psychology, devoted to understanding the relation between physical stimuli (e.g., ingredients, processes) and subjective response. When applied to developing food products for commercial use, psychophysics takes on a new role, as a center point in an evolving ecology of many unrelated but relevant disciplines and professions. We present a short history of the application of psychophysics to the world of food product design, and the ecosystems which grew around it, evolved, changed, and had to be reengineered to be relevant for the 21st century.

Why should educational researchers study the history of education? This article suggests that this research is of immediate relevance to current issues of education and may therefore serve a wide variety of purposes. The main argument is that history of education offers four vital contributions: a unique methodological expertise that in turn enables historians of education to provide educational research with vital explanations, comparisons, and the ability to analyse the use and abuse of history in contemporary educational policy and debate. In short, history of education is vital to educational research, not despite its historical orientation, but because of it. Consequently, this paper poses a challenge, both for the field of educational research to promote educational historical research, and for historians of education to explore the untapped potential of this sub-discipline.
