This chapter suggests a way Mesoamerican archaeologists can move beyond the Type-Variety system of ceramic classification. It offers evidence for a ceramic unit called the “ceramic set.” It is assumed consumers within a culture each had a similar range of serving and preparation needs and the range of formal variation found in different types of ceramics represented an effort by different producers to meet these needs. The range of forms found within one of these types a "ceramic set." Ceramic set are further defined as a series of forms that are similar in paste, slip, and surface treatment but which are used for a variety of serving needs. The chapter examines the evidence for ceramic sets in two Mesoamerica societies, the Toltec of Central Mexico (A.D. 900–1150) and the Maya of the Southern Lowlands (A.D. 700–1000) in an effort to provide a new method for identifying the nature of household activities in these societies. It also examines whether ceramic sets allow archaeologists to define evidence of innovation and competition in the production and distribution of ceramics in Pre-Columbian pottery economic systems.

Cementing Agent

The metal-free restorations are sought out due to aesthetic needs. The success of restorative treatment depends on the peculiarities of each ceramic system and on a proper strategy for cementing. This article presents the surface treatment of the interfaces involved during the cementing, the dental structure and restoration, and elucidates the cementing agent. It emphasizes the different types of surface treatment for acid-sensitive and acid-resistant ceramics, and hybrid ceramics. The literature review was based on scientific articles published in different database (PubMed, Medline, Scielo, Bireme and Google Scholar) using the keywords: prosthodontics, ceramics, surface treatment and cementation. Relevant articles were selected between 2002 and 2015 regarding the issue under review. The knowledge of dentists about the cementation strategies, depending on the type of ceramic used, is necessary for decision making during the cementing and promote the clinical success of treatment with metal-free restorations.

Abstract The quality of polarimetric radar rainfall estimation is investigated for a broad range of distances from the polarimetric prototype of the Weather Surveillance Radar-1988 Doppler (WSR-88D). The results of polarimetric echo classification have been integrated into the study to investigate the performance of radar rainfall estimation contingent on hydrometeor type. A new method for rainfall estimation that capitalizes on the results of polarimetric echo classification (EC method) is suggested. According to the EC method, polarimetric rainfall relations are utilized if the radar resolution volume is filled with rain (or rain and hail), and multiple R(Z) relations are used for different types of frozen hydrometeors. The intercept parameters in the R(Z) relations for each class are determined empirically from comparisons with gauges. It is shown that the EC method exhibits better performance than the conventional WSR-88D algorithm with a reduction by a factor of 1.5–2 in the rms error of 1-h rainfall estimates up to distances of 150 km from the radar.

Hydroxyapatite (HA) and other forms of bioceramics coatings had been reported to stimulate bone healing, which helps in initial implant integration. This study was to evaluate the effectiveness of air blasting with two combinations of bioceramic powders (hydroxyapatite and calcium oxide) on the selected implant surfaces for surface deposition. Five different types of implant disks were tested, namely Commercially pure (Cp), Sandblasted (SB), Sandblasted and etched(SBE), SLActive®, Roxolid®. The studied samples were blasted with apatite abrasive bioceramic powders, 95% Hydroxyapatite (HA)/5% Calcium Oxide (CaO) and 90% Hydroxyapatite (HA)/10% Calcium Oxide (CaO). The surface and elemental differences between the blasted samples were compared using a Scanning Electron Microscope (SEM) and Energy Dispersive Spectroscopy (EDS). Results after surface treatment had demonstrated changes in surface morphologies; most evidently on the Cp implant discs. All treated surfaces revealed a non-uniform distribution of the treatment on the surface layer, with dispersed patches of bioceramic powders over the surfaces. The experimental blasting method used in this study has demonstrated the ability to deposit bioceramic materials on different implant surfaces.

General Method

Demand calculation, which is the base of most logistics decisions and activities, is a critical work in humanitarian logistics (HL). However, previous studies on demand calculation in HL mainly focus on demand forecasting methodology, with many neglecting the checklist of critical supplies and practice background. This work proposes a new method for relief demand calculation by dividing the process into two parts: supply classification and demand calculation. A general method for classifying relief supplies and clarifying the checklist of relief items for multi-disaster and multiple natural scenarios is given in detail, followed by the procedure of demand calculation for each relief material. The authors present a case study to validate the feasibility and effectiveness of the proposed method based on the disaster response practice in China. Detailed lists of relief demand for different types and severities of disaster are provided.

This paper reviews currently available approaches and methods of automated population and enrichment of ontologies or ontology-based knowledge bases by structured data stored in various heterogeneous sources. Advantages and disadvantages of each approach are pointed out. The results of the analysis allow concluding that the existing methods are not effective enough to solve practical problems. A new method suggested does not have any of the specified disadvantages. The suggested method allows integrating data from different types of sources and considering the distributed nature of data and the necessity of authentication during accessing network resources. The method also suggests a solution to the problem of integrated data conflict resolution so that it will reduce the complexity of populating and enriching ontologies using the collected data arrays, irrespective of the format in which data are stored or represented.
