Bukhara and its neighborhood. Reassessing the cultural links of the oasis from new ceramic evidence

Ceramic assemblages from the Bukhara Oasis show an interesting mix of vessel forms and decorative styles, specifically in pre-Islamic times. Some elements of the tableware bear resemblance to material from adjacent regions in the south-west and south-east, including Margiana and Bactria, while others, specifically the storage vessels, appear to be inspired by the north-west or eastern areas, such as Khoresm and Chach. Surface coatings and slip paint proved to be highly significant in identifying these distinct cultural links.Drawing upon samples from the recent excavations by the MAFOUB project, this paper will trace the various cultural strains through analyzing the use of slip and slip-paint as an exemplary feature in the ceramic assemblages of the Bukhara Oasis from antiquity to the early Islamic period. Individual decorative patterns appear to be restricted to certain parts of the vessel repertoire. While coated vessels firmly belong to the tableware inventory, cursory applied slip paint with drizzling effects is mostly observed on containers and storage jars. Some slip painted decorations illustrate the considerable variation this technique enjoyed within the Bukhara Oasis.Our diachronic study highlights these diversities and follows the implied cultural alliances to shed light on Bukhara's position and role within the Central Asian neighborhood.

Cahokia's influence in the Yazoo Basin: a ceramic analysis of Early Mississippian features at the Carson site

ABSTRACT Ceramic assemblages from pithouses at the Carson site in Mississippi show distinctly nonlocal trends that indicate Cahokian influence in the region. This study evaluates pottery collections from multiple locations with a focus on vessel shapes, slips, and nonlocal types. A minimum number of vessels was established for two contexts at Carson, and those vessels were analyzed based on manufacturing processes and stylistic modifications. Through a comparison of Carson pottery with assemblages from Cahokian neighborhoods, there is clear overlap between the decorative and functional practices in both collections. Factors such as the use of slips, vessel assemblage compositions, and quantitative measures highlight the Cahokian origins of the assemblages at Carson. In investigating Cahokian use of the wider North American landscape, Trempealeau in Wisconsin provides a point of comparison to understand the settlement at Carson and its deviation from local norms. In placing Cahokia in a wider context of interregional interactions, it is clear that landscapes and regions outside of the American Bottom such as that at Carson played a role in Cahokia's rise early in its history.

Ефективність різних способів вирощування посадкового матеріалу батата (Ipomoеa BatаtaS)

The purpose of the study was to establish the effectiveness of different methods of obtaining sweet potato planting material (through potted seedlings or unrooted cuttings) in the Left-Bank Forest-Steppe of Ukraine. Research methods: field, laboratory, statistical.The use of pottedseedlings method as a method of obtaining sweet potato planting material provides the formation of more developed plants of the culture (with an increased number of shoots per plant and their total length).The use of slips as a method of obtaining sweet potato planting material provides more intensive growth rates, the formation of tuber yields at 14.8 t / ha with a high content of dry matter (13.8 %), starch (10.7 %) and vitamin C 5.33 mg / 100 g).Using potted sweet potato seedlings occur with deformed tubers (3.5 %), but decreases the proportion of shrubs that do not form the tubers (8.3 % compared to 10.0 % for the use of the slips).

Slip and antiblock additives: surface medication for film and sheet

Modifying the surface of polymer film and sheet through the use of slip and antiblock additives can either improve performance in fabrication or downstream packaging equipment, or the end-use performance of the polymer. Jennifer Markarian explains.

Permeability of diatomite layers processed by different colloidal techniques

Recently, efforts have been directed towards the development of ceramic filters for water treatment systems in which the microstructure is tailored to the application, is well characterised and is reproducible. This work reports on the use of slip and tape casting techniques, as well as a new “direct consolidation technique”, to obtain porous diatomite layers for filtration purposes. Diatomite has been chosen because of its low price, abundance, and intrinsic properties such as high porosity and small grain size. Layers prepared by tape casting and lamination, with a bending strength of 57 MPa, were almost 3 times stronger but less permeable than those produced by slip casting, due to the presence of binders and to the lamination step that promoted particle rearrangement. However, both forming techniques gave relatively low permeable layers due to fine (0.25–0.6 μm) and monomodal pore size distributions. The use of starch granules (30–50 wt%) as pore former and consolidator agents enabled to increase the permeability of sintered bodies for almost one order of magnitude as a result of the increasing amount and average size of pores. As expected, porosity and average pore size values show a direct dependence on the starch content.

Arthroscopic Knot Tying Techniques

Summary: The development of arthroscopic shoulder reconstructive procedures has required the passage of sutures and tying of knots down a cannula. Successful accomplishment of this goal requires an understanding of both suture handling and knot tying techniques, in order to avoid tangles in the cannula, premature locking of knots, and inadequate knot seating. This article presents an overview of arthroscopic knot tying techniques. It explains a variety of knots by diagram, and will provide an understanding of the application and use of slip and nonsliding knots in arthroscopic surgery.Arthroscopy: The Journal of Arthroscopic and Related Surgery, Vol 15, No 5 (July-August), 1999: pp 515–521

Porosity development of diatomite layers processed by tape casting

The processing from colloidal suspensions is a good method to obtain bodies with low microstructural heterogeneities, by careful control of the interfacial stresses. In previous papers we described the use of slip and tape casting techniques to obtain diatomite porous layers, having controlled morphology such as the amount and size of pores. The present work reports the use of tape casting bodies for filtration purposes. As the maximum thickness of the layers produced by tape casting is about 0.3 mm, their mechanical resistance is very low. It was necessary to produce thicker compacts made by several single layers (up to 20), obtained by thermocompression at different temperatures between 20 and 90 °C followed by sintering at 1200 °C. By selecting a careful heating programme, final bodies with 0.6–1.3 mm thickness were obtained, having porosity levels of about 44% and pore sizes between 0.1 and 1μm. High bending strength values (57 MPa) were obtained, enough to support mechanical stresses in use as a membrane. Permeability to an air flux was evaluated as a function of relevant morphological parameters (porosity, thickness, etc.).

SLIP, a lipid suppression technique to improve image contrast in inflow angiography

In rapidly acquired gradient echo images, lipid regions usually appear as areas of high signal intensity. In 2D inflow angiograms processed by the maximum intensity projection algorithm, this high lipid signal may prevent angiographic visualization of some blood vessels. We present a new approach to suppress the lipid signal, SLIP, spatially separated lipid presaturation. The SLIP technique suppresses lipid signal over a narrow region by exploiting the chemical-shift effect. SLIP requires an arrangement of a thin slice and a wide presaturation slab already available in 2D inflow refreshment angiography. Thus SLIP was incorporated to an inflow angiography sequence without increasing the acquisition time. The use of SLIP resulted in considerable improvement in angiographic contrast and increased the number of vessels detected in projection angiograms. The SLIP technique does not require high homogeneity of the main magnet field.

The role of slip in the rheology of blood.

The use of slip as a mechanism in explaining the predicting blood flow is shown to lead to inconsistent results when the over-all rheological properties as well as the velocity profile is considered. The evidence for slip is also considered and shown

The introduction of a paging technique into the symmetric list processor, SLIP

When the computing community turned its attention back to the problem of "pure" symbol manipulation, a large and ever-growing family of "list-processing" ("LP") computer languages resulted. SLIP, which is one of these, was primarily written in FORTRAN, making it easy to use, understand and debug. The widespread use of SLIP, however, has been severely hampered by the restriction of available space in the system. Guided by the desire for more available space, we imposed upon our study the conditions that as few changes as possible should be made to the SLIP system, and additions to the system should be automatic functions of the system and not of the user. This report shows how a paging technique incorporated into the SLIP system accomplished our goal.
