Monographs and other recent works are reviewed to highlight several trends in Old World archaeology that seem to be of more than passing interest to archaeologists whose primary research interests are in the Americas. Included in this review are works involving natural historical studies applied to archaeology; current works involving lithic and ceramic technology, spatial analysis, and intrasite and intersite community studies; and recent works on questions of early food production and selected other topics. This paper, the first of an anticipated annual exchange between the Archaeological Institute of America and the Society for American Archaeology, emphasizes prehistoric studies; subsequent contributions will treat a fuller range of Old World archaeological interests.

Immobilization Method

Immobilization techniques are generally based on reusing enzymes in industrial applications to reduce costs and improve enzyme properties. These techniques have been developing for decades, and many methods for immobilizing enzymes have been designed. To find a better immobilization method, it is necessary to review the recently developed methods and have a clear overview of the advantages and limitations of each method. This review introduces the recently reported immobilization methods and discusses the improvements in enzyme properties by different methods. Among the techniques to improve enzyme properties, metal–organic frameworks, which have diverse structures, abundant organic ligands and metal nodes, offer a promising platform.

This chapter examines the changing face of agribusiness in the Middle West. It explains how agribusiness transformed large sections of the Middle West during the last third of the twentieth century and was reshaped as it became part of a global food production and marketing system. The transformation was particularly evident in the region's increasing emphasis on packaged-food production, ranging from frozen dinners for wholesale and retail markets to boxed beef and poultry for fast-food franchises. Commercial feedlots, animal-slaughtering facilities, and poultry-processing and meatpacking plants appeared with increasing frequency in southwest Kansas, western Oklahoma, central and eastern Nebraska, western Iowa, parts of Minnesota and South Dakota, and northwestern Arkansas. The chapter considers why small towns provided an attractive venue for large agriculture-related businesses in the Middle West. It looks at the case of Garden City, Kansas, to illustrate the long-term as well as recent developments in heartland agribusiness.

Background: The increasing population of humans, changing food consumption behavior, as well as the recent developments in the awareness for food sustainability, lead to new challenges for the production of food. Advances in the Internet of Things (IoT) and Artificial Intelligence (AI) technology, including Machine Learning and data analytics, might help to account for these challenges. Scope and Approach: Several research perspectives, among them Precision Agriculture, Industrial IoT, Internet of Food, or Smart Health, already provide new opportunities through digitalization. In this paper, we review the current state-of-the-art of the mentioned concepts. An additional concept is Food Informatics, which so far is mostly recognized as a mainly data-driven approach to support the production of food. In this review paper, we propose and discuss a new perspective for the concept of Food Informatics as a supportive discipline that subsumes the incorporation of information technology, mainly IoT and AI, in order to support the variety of aspects tangent to the food production process and delineate it from other, existing research streams in the domain. Key Findings and Conclusions: Many different concepts related to the digitalization in food science overlap. Further, Food Informatics is vaguely defined. In this paper, we provide a clear definition of Food Informatics and delineate it from related concepts. We corroborate our new perspective on Food Informatics by presenting several case studies about how it can support the food production as well as the intermediate steps until its consumption, and further describe its integration with related concepts.

Pesticides have vastly improved life for the developed nations of the world. Some developing nations lose a tremendous amount of their limited food production between harvest and consumer. It has been estimated that almost one-half of India's food production is destroyed by pests after harvest. This is a tragic loss in a nation where starvation and malnutrition are man's constant companions. Modem chemicals and pest control methods could reduce this loss in a short time. Research has continued to provide new insecticides as fast as insects have developed resistance. Unfortunately many insects have been able to develop a cross resistance to some pesticides. In other words, instead of only being resistant to malathion, diazinon, and other organic phosphates, some insects have also exhibited resistance to carbamate materials. At present no one has the answer to this resistance problem, but many people are working on it and it is not inconceivable that a solution will be found. In spite of resistance, residue tolerances, and increasing governmental restrictions, pesticides are still necessary to maintain our standards of sanitation. As regulations increase, the cost of developing new pesticides increases and the number of new compounds reaching the commercial market decreases. This decrease has been quite apparent in the past few years. If the present trend continues, it is conceivable that one day the flow of new materials will be dangerously low. At that time new approaches to replace residuals and other pesticides will be vitally important. The new chemicals, equipment, and techniques discussed will only be useful to the food industry if they are applied. Now is the time for all good sanitarians to come to the aid of their company and their country. Increasing costs, rising purity standards, and tightening regulations will tax the managerial and technical abilities of the food industry. Our sanitation programs must be constantly ahead of requirements. Food processors cannot complacently say, “we meet specifications,” because the “specifications” continually evolve toward purer food and more sanitary processing facilities.

Recent Developments

Food packaging has a crucial function in the modern food industry. New food packaging technologies seek to meet consumers and industrial's demands. Changes related to food production, sale practices and consumers' lifestyles, along with environmental awareness and the advance in new areas of knowledge (such as nanotechnology or biotechnology), act as driving forces to develop smart packages that can extend food shelf-life, keeping and supervising their innocuousness and quality and also taking care of the environment. This review describes the main concepts and types of active and intelligent food packaging, focusing on recent progress and new trends using biodegradable and biobased polymers. Numerous studies show the great possibilities of these materials. Future research needs to focus on some important aspects such as possibilities to scale-up, costs, regulatory aspects, and consumers' acceptance, to make these systems commercially viable.

Primary Electrons

The physical foundations for the use of electron energy loss spectroscopy towards analytical purposes, seem now rather well established and have been extensively discussed through recent publications. In this brief review we intend only to mention most recent developments in this field, which became available to our knowledge. We derive also some lines of discussion to define more clearly the limits of this analytical technique in materials science problems.The spectral information carried in both low ( 0<ΔE<100eV ) and high ( >100eV ) energy regions of the loss spectrum, is capable to provide quantitative results. Spectrometers have therefore been designed to work with all kinds of electron microscopes and to cover large energy ranges for the detection of inelastically scattered electrons (for instance the L-edge of molybdenum at 2500eV has been measured by van Zuylen with primary electrons of 80 kV). It is rather easy to fix a post-specimen magnetic optics on a STEM, but Crewe has recently underlined that great care should be devoted to optimize the collecting power and the energy resolution of the whole system.

At the light microscope level the recent developments and interest in antibody technology have permitted the localization of certain non-microtubule proteins within the mitotic spindle, e.g., calmodulin, actin, intermediate filaments, protein kinases and various microtubule associated proteins. Also, the use of fluorescent probes like chlorotetracycline suggest the presence of membranes in the spindle. Localization of non-microtubule structures in the spindle at the EM level has been less rewarding. Some mitosis researchers, e.g., Rarer, have maintained that actin is involved in mitosis movements though the bulk of evidence argues against this interpretation. Others suggest that a microtrabecular network such as found in chromatophore granule movement might be a possible force generator but there is little evidence for or against this view. At the level of regulation of spindle function, Harris and more recently Hepler have argued for the importance of studying spindle membranes. Hepler also believes that membranes might play a structural or mechanical role in moving chromosomes.
