The papers in this edition of the MRS BULLETIN were among those presented during a workshop entitled “SAS Interfaces '87: Microscopy for the Archaeologist.” The workshop was sponsored by the Society for Archaeological Sciences at the 52nd annual meeting of the Society for American Archaeology held in Toronto, Ontario, May 1987. The Society for Archaeological Sciences is an interdisciplinary professional society for researchers involved in the broad spectrum of physical science applications to archaeology in order to promote interaction among scientists interested in different aspects of common research problems.Archaeometry, i.e., “archaeological science,” is concerned with the physical analysis of archaeological materials and the application of techniques from the laboratory sciences to the objectives and needs of archaeology. It includes such activities as compositional analysis, reconstruction of past technologies and processes, remote sensing, paleo-environmental reconstruction, and of course, isotopic and other chronometric dating methods. Such techniques alone, however, yield results that mean little without appropriate application to anthropological problems. The chief concern of archaeologists is to choose the most appropriate analysis method to achieve results that are useful in interpreting cultural behavior. To that end, laboratory analysts need to be aware of the interests and concerns of archaeologists, and archaeologists need to be able to understand the technical advances in archaeometry to incorporate them into their research.

Studying the factors affecting the income of Vietnamese peasants: A case in Tra Vinh province, by data collection method of 170 peasants’ households in 4 districts: Cau Ngang, Cang Long, Chau Thanh and Tieu Can in Tra Vinh province, Vietnam. The authors use multivariate regression analysis method. The study has found the factors such as gender of households’s heads, ages of households’ heads, education levels, the number of family members, dependency rates, application of technical advances, production areas affecting the income of peasants in these areas. Since then, the study has implied a policy to improve the income of peasants. For example, it could be very important for us to focus on training science and technology in agriculture, diversify crops and livestock in agriculture, improve techniques and enhance education levels to increase income for peasants in Tra Vinh province in the future.

Tom Krogh revolutionized the field of precise U–Pb geochronology through a series of ground-breaking technical advances in the 1970s and 1980s that changed our investigative approach to understanding geologic processes. Earth scientists around the world have used his dating methods for more than 30 years to produce high-precision ages that have advanced our knowledge of Earth’s evolution through time. Tom applied these techniques to investigate the formation of ancient crust in the Superior and Grenville provinces, and other orogens, and the timing of terrestrial impacts. His legacy is built upon these scientific contributions, the many people he trained and inspired, and the global distribution of laboratories that use his methods.

Tunjuk Ajar Melayu (TAM) is very important for Malay people, especially in the past trying after all their power to disseminate, bequeath and perpetuate the teaching values ​​referred to through literature (both oral and written). Understanding and living a literary work, one of which is through the study of stylistics. Stylistics as one of the sub-sciences in literature plays a large role in the study of literature because it examines the way the writer uses elements and language rules by looking for the effects caused by the use of language, examining the characteristics of the use of language in literature. Stylistics studied the use of the figure of speeches in its function. In this study, the researcher formulated the research problems, what was the comparative and linkage figure of speeches in TAM by Tenas Effendy?. Therefore, this research was conducted to describe, analyze, and interpret the comparative and linkage figure of speeches contained in TAM by Tenas Effendy. This research used the content analysis method. The data was collected through documentation and hermeneutic techniques. The data was documented by reading, taking notes, then summarizing and grouping according to the type of work. The results of this study were comparative figure of speeches in TAM by Tenas Effendy consisting of simile, personification, metaphor, and allegory. The linkage figure of speech in TAM by Tenas Efendy consisted of synecdoche figure of speech of tutom pro parte category.

Abstract Destructive physical analysis (DPA) is one of the reliability evaluation methods, which observes defects and faults in a device, and it can classify the reliability level of the device. After a description of the current method for Au wires, this paper explains the DPA for a Cu wire device. The DPA for semiconductor devices is divided roughly into three steps: a non-destructive inspection, an assembly process inspection, and a wafer process inspection. Investigation of DPA for Cu wire device includes wire material identification, optimization of decapsulation for Cu wire device and wire pull strength test, and observation of package cross-section. From the result, novel sample preparation (embedding a sample in molding package and forming the package to be suitable for cross-sectional observation by ion polishing) enables the observation of the thin alloy layer at the wire/pad interface.

The importance of being able to date accurately the remains of past societies has long been recognized by archaeologists. The problem has always been to find methods that work in the absence of historical records. Recent developments, such as tree-ring dating, have been great contributions, but they are not applicable everywhere. There is still a great need for new methods to supplement and extend the range of present dating procedures.A large field of knowledge so far largely unexplored for possible dating methods is the physics and chemistry of archaeological remains. One area in this field is the study of naturally occurring radioactive elements. Some of these elements have been used by geologists to date ancient rock strata, but applications to archaeological materials have not been made. Recently, however, two possible methods for using radioactive elements to date archaeological remains have been proposed on theoretical grounds. It is not yet definitely known whether they will work, or how well. Further research is necessary.

Purpose – The purpose of this paper is to focus on examining the research impact of papers written with and without funding. Specifically, the citation analysis method is used to compare the general and funded papers published in two leading international conferences, which are ACM SIGIR and ACM SIGKDD. Design/methodology/approach – The authors investigate the number of general and funded papers to see whether the number of funded papers is larger than the number of general papers. In addition, the total citations and the number of highly cited papers with and without funding are also compared. Findings – The analysis results of ACM SIGIR papers show that in most cases the number of funded papers is larger than the number of general papers. Moreover, the total captions, the average number of citations per paper, and the number of highly cited papers all reveal the superiority of funded papers over general papers. However, the findings are somewhat different for the ACM SIGKDD papers. This may be because ACM SIGIR began much earlier than ACM SIGKDD, which relates to the maturity of the research problems addressed in these two conferences. Originality/value – The value of this paper is the first attempt at examining the research impact of general and funded research papers by the citation analysis method. The research impact of other research areas can be further investigated by other analysis methods.

Abstract The electrochemical behaviour of steel, copper, and titanium current collectors was studied in aqueous solutions of lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) at various concentrations, from 0.5 up to 20 m. As the concentration of the electrolyte increases, the electrochemical window of water stability widens according to the “water-in-salt” concept. The metal grids have been studied electrochemically, both under anodic and cathodic conditions, by means of cyclic voltammetry and chronoamperometry. Subsequently, a microscopic analysis with SEM and compositional analysis with XPS was carried out to evaluate the surface modifications following electrochemical stress. We found that copper is not very suitable for this kind of application, while titanium and steel showed interesting behaviour and large electrochemical window.

Protozoan parasites are fearsome pathogens responsible for a substantial proportion of human mortality, morbidity, and economic hardship. The principal disease agents are members of the orders Apicomplexa (Plasmodium, Toxoplasma, Eimeria) and Kinetoplastida (Trypanosomes, Leishmania). The majority of humans are at risk from infection from one or more of these organisms, with profound effects on the economy, social structure and quality of life in endemic areas; Plasmodium itself accounts for over one million deaths per annum, and an estimated 4 × 107 disability-adjusted life years (DALYs), whereas the Kinetoplastida are responsible for over 100,000 deaths per annum and 4 × 106 DALYs. Current control strategies are failing due to drug resistance and inadequate implementation of existing public health strategies. Trypanosoma brucei, the African Trypanosome, has emerged as a favored model system for the study of basic cell biology in Kinetoplastida, because of several recent technical advances (transfection, inducible expression systems, and RNA interference), and these advantages, together with genome sequencing efforts are widely anticipated to provide new strategies of therapeutic intervention. Here we describe a suite of methods that have been developed for the microscopic analysis of T. brucei at the light and ultrastructural levels, an essential component of analysis of gene function and hence identification of therapeutic targets.
