On Enabling Compliance of Cross-Organizational Business Processes

Process compliance deals with the ability of a company to ensure that its business processes comply with domain-specific regulations and rules. So far, compliance issues have been mainly addressed for intra-organizational business processes, whereas there exists only little work dealing with compliance in the context of cross-organizational processes that involve multiple business partners. As opposed to intra-organizational processes, for a cross-organizational process, compliance must be addressed at different modeling levels, ranging from interaction models to public process models to private processes of the partners. Accordingly, there exist different levels for modeling compliance rules. In particular, we distinguish between local compliance rules of a particular partner and global compliance rules to be obeyed by all partners involved in the cross-organizational process. This paper focuses on checking the compliance of interaction models. For this purpose, we introduce the notion of compliability, which shall guarantee that an interaction model is not conflicting with a set of imposed global compliance rules

Towards Compliance of Cross-Organizational Processes and their Changes

Businesses require the ability to rapidly implement new processes and to quickly adapt existing ones to environmental changes including the optimization of their interactions with partners and customers. However, changes of either intra- or cross-organizational processes must not be done in an uncontrolled manner. In particular, processes are increasingly subject to compliance rules that usually stem from security constraints, corporate guidelines, standards, and laws. These compliance rules have to be considered when modeling business processes and changing existing ones. While change and compliance have been extensively discussed for intra-organizational business processes, albeit only in an isolated manner, their combination in the context of cross-organizational processes remains an open issue. In this paper, we discuss requirements and challenges to be tackled in order to ensure that changes of cross-organizational business processes preserve compliance with imposed regulations, standards and laws

The Development and Scope of Method-Study in Mining

For rationalization of mining operations, there has lately been an increasing application of method-study techniques. The author here reviews the recent developments in this field and discusses the scope of application of the techniques to the mining industry for attaining higher productivity and economy

Hydraulic Stowing in Mines - Some Theoretical Design considerations

Some theoretical aspects of gravity flow of sand/water mixtures in stowing systems are examined here in the context of the pioneering work on hydraulic transport of solids carried out by Durand and condolios in France. The theoretical considerations on the design of stowing systems with special reference to pipeline layout and the maximum delivery and range of stowing are presented in the paper. An account of the developments in design in the stowing installations in France is also given by the author

Natural Coke (Jhama), its Properties and Possible Utilization

It has been estimated that about 400 million tones of natural coke (Jhana) exists in the Jharia coalfield. Apart from difficulties of mining this hard material, its utilization is the biggest stumbling block in its winning. The paper makes a study of the different properties of natural coke from different sources of the Jharia coalfield with a view to studying the potentialities of its use. Some of the important observations are – the very low melting point of the ash and very good combustion characteristics when the material is crushed to a particular size. The first property suggests the possibility of its utilization in furnaces where a molten ash is desirable for ease of removal and the second property suggests its possible utilization as a domestic fuel. The formation of the natural coke must have taken place at a temperature of above 600ºC but not exceeding 900ºC. the composition of ash indicates reaction of the intrusive material with coal during the formation of natural coke

Determination of genetic variations among different Trichoderma isolates using RAPD marker in Bangladesh

Some Trichoderma isolates were collected from different locations of Bangladesh for evaluating their bioefficiency by determining their genetic variations. PCR-based Random Amplified Polymorphic DNA (RAPD) Marker employing 3 decamer primers produced 29 scorable bands of which all (100%) were polymorphic. The co-efficient of gene differentiation (Gst) was 1.0000 reflecting the existence of high level of genetic diversity among the isolates. The Unweighted Pair Group Method of Arithmetic Means (UPGMA) dendrogram constructed from Nei’s (1972) genetic distance produced 2 main clusters (16 isolates in cluster 1 and 19 isolates in cluster 2). The result indicating their genetic diversity has opened new possibility of using the most efficient and more isolates of Trichoderma in the preparation of effective biopesticide

Slurry Erosion Behavior of Destabilized and Deep Cryogenically Treated Cr-Mn-Cu White Cast Irons

The effects of destabilization treatment and destabilization followed by cryogenic treatment have been evaluated on the microstructural evolution and sand-water slurry erosion behavior of Cr-Mn-Cu white cast irons. The phase transformations after the destabilization and cryotreatment have been characterized by bulk hardness measurement, optical and scanning electron microscopy, x-ray diffraction analysis. The static corrosion rate has been measured in tap water (with pH=7) and the erosion-corrosion behavior has been studied by slurry pot tester using sand-water slurry. The test results indicate that the cryogenic treatment has a significant effect in minimizing the as-cast retained austenite content and transforming into martensitic and bainitic matrix embedded with ultra-fine M7C3 alloy carbides. In contrast, by conventional destabilization treatment retained austenite in the matrix are not fully eliminated. The slurry erosive wear resistance has been compared with reference to destabilized and cryotreated high chromium iron samples which are commonly employed for such applications. The cryotreated Cr-Mn-Cu irons have exhibited a comparable erosive wear performance to those of high chromium irons. Higher hardness combined with improved corrosion resistance result in better slurry erosion resistance

Correlation of Seams on the Basis of Chemical Analysis and Coal Properties in Kasta Area, Raniganj Coalfield

In course of the physical and chemical survey of coals from kasta seam, Raniganj Coalfield, it was observed that the properties of the coal substance and the quality of coal very abruptly from one area to another, one kilometer apart. Coals from the western part are better in quality and higher in rank than those form remaining eastern part. Such variation of properties observed in coals occurring in so close a proximity is far from normal. Higher moisture content of the coals form the eastern part is another peculiar feature not so far observed in coals from the Barakar Measure of the Raniganj coalfield. General lithological character of the seams concerned spore analysis mineral matter and petrographic make-up are different in case of coals from either side. Such nature of the coals can only be reconciled if it is proved that the seams are different, which opens the prospect of the existence of the reputed Kasta seam as observed in the western sector below the present workings of the other side. Further deep drilling in strategic positions only can confirm the view
