The pottery from the sites of the Tchefuncte period has been classified into a number of different types. As used by us, the type is a kind of average of an arbitrarily limited range of overlapping traits which have been abstracted from whole vessels and sherds that appear to be similar. Typology is checked against stratigraphy and stratigraphy against typology, to determine the utility of the type as an indicator of cultural change in time and space. Following are descriptions of the pottery types found in sites of the Tchefuncte period.Paste.—Method of Manufacture: Coiled. Sherds break readily along coil junctions. Flattened coils average 3-4 cm. wide.Tempering: Angular particles of clay. Small amount of fine sand. There are occasionally small particles of carbonized vegetal material and rarely bits of red ochre.Texture: Clay of paste is very fine. Clay was very poorly wedged, and this feature, added to the large angular tempering particles, gives a laminated and contorted appearance to cross sections of sherds. Surfaces have been floated and are soft and chalky.

Drawings, illustrations, and field sketches play an important role in Earth Science since they are used to record field observations, develop interpretations, and communicate results in reports and scientific publications. Drawing geology in the field furthermore facilitates observation and maximizes the value of fieldwork. Every geologist, whether a student, academic, professional, or amateur enthusiast, will benefit from the ability to draw geological features accurately. This book describes how and what to draw in geology. Essential drawing techniques, together with practical advice in creating high quality diagrams, are described the opening chapters. How to draw different types of geology, including faults, folds, metamorphic rocks, sedimentary rocks, igneous rocks, and fossils, are the subjects of separate chapters, and include descriptions of what are the important features to draw and describe. Different types of sketch, such as drawings of three-dimensional outcrops, landscapes, thin-sections, and hand-specimens of rocks, crystals, and minerals, are discussed. The methods used to create technical diagrams such as geological maps and cross-sections are also covered. Finally, modern techniques in the acquisition and recording of field data, including photogrammetry and aerial surveys, and digital methods of illustration, are the subject of the final chapter of the book. Throughout, worked examples of field sketches and illustrations are provided as well as descriptions of the common mistakes to be avoided.

AbstractNegative ion collision-induced dissociation (CID) of underivatized N-glycans has proved to be a simple, yet powerful method for their structural determination. Recently, we have identified a series of such structures with GalNAc rather than the more common galactose capping the antennae of hybrid and complex glycans. As part of a series of publications describing the negative ion fragmentation of different types of N-glycan, this paper describes their CID spectra and estimated nitrogen cross sections recorded by travelling wave ion mobility mass spectrometry (TWIMS). Most of the glycans were derived from the recombinant glycoproteins gp120 and gp41 from the human immunodeficiency virus (HIV), recombinantly derived from human embryonic kidney (HEK 293T) cells. Twenty-six GalNAc-capped hybrid and complex N-glycans were identified by a combination of TWIMS, negative ion CID, and exoglycosidase digestions. They were present as the neutral glycans and their sulfated and α2→3-linked sialylated analogues. Overall, negative ion fragmentation of glycans generates fingerprints that reveal their structural identity.

This case study was developed from an actual scenario by Dr. Steve Leybourne of Boston University.  The case documents the historical evolution of an organization, and has been used successfully in courses dealing with organizational and cultural change, and the utilization of ‘soft skills’ in project-based management.This is a short case, ideal for classroom use and discussion.  The issues are easily accessible to students, and there is a single wide ranging question that allows for the inclusion of many issues surrounding strategic decision-making, and behavioural and cultural change.Alpha was one of the earlier companies in the USA to invest in large, edge-of-town superstores, with plentiful free vehicle parking, selling food and related household products.Alpha was created in the 1950s as a subsidiary of a major publicly quoted retail group.  It started business by opening a string of very large discount stores in converted industrial and warehouse premises in the south of the United States. In the early days shoppers were offered a limited range of very competitively priced products.When Alpha went public in 1981 it was the fourth largest food retailer in the US, selling an ever-widening range of food and non-food products.  Its success continued to be based on high volume, low margins and good value for money, under the slogan of ‘Alpha Price.’

Abstract The aim of the study is to reconstruct the development of landslide relief in the Kamienne Mountains (Central Sudetes, SW Poland) based on a DEM from LiDAR data. Analyses of relief and geological maps in ArcGIS 10.5 and of slope cross-sections in Surfer 14 allowed to distinguish different types of landslide relief, developed in latites and trachybasalts lying above claystones and mudstones. The types vary from small, poorly visible landslides to vast landslides with complex relief. They were interpreted as consecutive stages of geomorphic evolution of hillslope-valley topography of the study area. Two main schemes have been established which explain the development of landslide slopes in the Kamienne Mts: (1) upslope, from the base of the slope towards the mountain ridge and (2) downslope, beginning on the top of the mountain ridge. The direction of landslide development depends on the thickness of volcanic rocks in relation to underlying sedimentary rocks. When the latter appear only in the lowest part of the slope, landslides develop upslope. If sedimentary rocks dominate on the slope and volcanic rocks form only its uppermost part, landslides develop downslope. The results show that landsliding leads to significant modifications of relief of the study area, including complete degradation of mountain ridges.

It is a scene of devastation, as far as the eye can see. Swathes of bleak landscape, with strewn boulders embedded in a sticky mass of sandy clay. Here and there are signs of a little more order—distinct spreads of gravel or patches of fine sand. Mostly, though, it looks as though every type of sediment, from fine clay to house-sized blocks, has simply been stirred together and spread across the land. Remove the crops and topsoil of gentle Leicestershire and Suffolk, or of central Germany or Kansas, and this is what lies beneath. Between the ordered sedimentary strata of the distant geological past and the ordered calm of the present is evidence of an only-just-elapsed catastrophe, and two centuries ago, when the science of the Earth was young, the naturalists of those days pondered on what it might mean. There were those like the young William Buckland, both Reader in mineralogy at Oxford and priest (he went on to become Dean of Westminster), who saw in it evidence of the biblical Deluge. Or Jean André de Luc, mentor to the wife of George III, who considered that the large blocks had been fired, like Roman ballista, from the mountains by some powerful but mysterious explosions. Or Sir James Hall, a savant of Edinburgh, who thought that the blocks had been carried into position by tsunamis, generated when large areas of sea floor (he supposed) suddenly popped up like blisters—he was clearly of an intellectually playful disposition. Or Leopold von Buch, who invoked catastrophic mudflows (one such, indeed, did take place in an Alpine valley, the Val de Bagnes, just after von Buch’s paper on this topic was published, when a natural dam burst, scattering mud and boulders far down the valley, and killing many people). But it was that extraordinary polymath, Johann Wolfgang von Goethe (a one-time Superintendent of Mines, if you please) who was among the first to sense what had been going on, when he associated the scattered blocks with a great expansion of the Alpine glaciers he was familiar with, and coined the term Eiszeit —the Ice Age.

Chapter 5 continues to engage with theory, meta-methodology, and methodology through a novel synthesis of work on scalarity, intimacy, stancetaking, chronotopicity, kinship, and narrative. After defining intimacy as “. . . an emergent feeling of closeness in combination with significant levels of vulnerability, trust, and/or shared identities that can very across time and space” (Perrino & Pritzker, 2019), it goes on to provide the reader with a discursive and procedural view of what intimacy, vulnerability, and trust look like. In doing so, this chapter provides a discursive picture to terms that have often been associated with the notion of rapport while demonstrating that close attention to the discursive features of anthropological interviews not only provides unique insights into the co-construction of different types of rapport but also offers further evidence that challenges the notion that one needs to establish rapport before engaging in interviews. More specifically, Perrino explores how the co-construction of intimacy becomes a central aspect of researcher/collaborator’s rapport in anthropological fieldwork settings. She shows how intimate relations are processual phenomena of interaction in speech participants’ oral narratives as they unfold in interview settings in two field sites: Senegal (West Africa) and Northern Italy. In doing so, she highlights how kinship chronotopes are also discursively appropriated and co-constructed as part of both her and her consultants’ ongoing efforts to inhabit particular participant roles (i.e., to engage in role alignment).

Abstract Ultrasonic joining is a common industrial process. To build electrical connections in the electronics industry, uni-axial and torsional ultrasonic vibration have been used to join different types of workpieces for decades. Many influencing factors like ultrasonic power, bond normal force, bond duration and frequency are known to have a high impact on bond quality and reliability. Multi-dimensional bonding has been investigated in the past to increase ultrasonic power and consequently bond strength. This contribution is focused on the comparison of circular, multi-frequency planar and uniaxial vibration trajectories used for ultrasonic bonding of copper pins on copper substrate. Bond quality was analyzed by shear tests, scanning acoustic microscopy and interface cross-sections.

Nowadays the process through which the sandstone craft products are produced at North Singapadu Village has changed. The appearance of different types of popular sandstone craft products reflecting the local identity produced by the young craftsmen at North Singapadu Village shows this. Such products are different from the traditional sandstone craft ones in terms of form and aesthetic style. Globalization, ideology and technology have basically led to the change. The sandstone industry has become highly innovative. This present study uses the qualitative and interpretative method and the theories used are the theory of acculturation, the theory of deconstruction, and the theory of postmodern aesthetics.              The conclusion of the present study is that the form and process of innovation initially resulted from new ideas and concepts and the craftsmen’s paradigm. The main things which have been responsible for changing the traditional way of life into the modern way of life are formal education, tourism and modern technologies. Those who are positively and negatively affected by globalization are not only the capital owners and craftsmen but the villagers and consumers as well. The sandstone craft products at North Singapadu Village contain the meaning of creativity, the economic meaning, the commodificative meaning and the meaning of cultural change. The finding of the study shows that the craftsmen at North Singapadu Village have ignored the traditional concepts, the technique of producing the products, and the materials used. However, the sandstone craft products at North Singapadu Village do not get extinct but remain to exist and both domestic and foreign consumers are interested in them.

AbstractIn this paper, energy slope averaging in the one-dimensional steady gradually varied flow model is considered. For this purpose, different methods of averaging the energy slope between cross-sections are used. The most popular are arithmetic, geometric, harmonic and hydraulic means. However, from the formal viewpoint, the application of different averaging formulas results in different numerical integration formulas. This study examines the basic properties of numerical methods resulting from different types of averaging.
