In Sheldon s scenario, the Asian reserves are distorted by countries that might be more properly termed Middle Eastern countries and that are aligned for all practical purposes with North African producers. Of Asia s total reserves (1.3 x 10 tonnes), 68% may be ascribed to Iraq, Israel, and Jordan. The other reserves category for Asia may also include other Middle Eastern countries. China is the one distinctly Asian country in this category, and its reserves are rather limited (170 million tonnes). 

Indicated reserves" (category Cl) are determinable at the end of the second stage of an exploration project for cement raw materials. These have been investigated on the basis of a network of widely spaced boreholes the types of rock and their chemical characteristics are substantially known, as are also the structure and bedding conditions in broad outline. 

Finally, the "inferred reserves" (category C2) are those which are tentatively determined as the resu It of the first exploration stage, in which the deposit has been prospected by means of a limited number of individually located boreholes, so that the chemical characteristics and structure of the deposit are known in an approximate and general way. 

In South America, Vene2uela continues to dominate in the proved reserve and the production categories. Since 1978, reserves of cmde petroleum in Vene2uela have increased from 2.9 x 10 (18.2 x 10 bbl) to 10.0 x 10 (62.6 x 10 bbl), neady doubling its share of the wodd s proved reserves... 

The key factor influencing the varying interpretations is that although there is an enormous volume of petroleum resources in the ground throughout the world, it is found in deposits that differ in quaUty and quantity from country to country. Only a small fraction of these resources are conventional petroleum resources (160.1 x 10 m (1006.8 x 10 bbl)) and are in the category of proved reserves. An additional... 

Project delineates between cleaner new gas technologies and polluting old natural gas technologies—and reserves a third cleanest category for energy efficiency/conservation, solar, wind, and geothermal (but not hydro or biomass). 

Features. Seven categories of bearing design and gauge protection are defined as features. Features 8 and 9 are reserved for future use. 

In Russia, the Commonwealth of Independent States, Bulgaria, Czech Republic, Slovakia, and Croatia, the amounts of gas in this category are calculated for undrilled structures and horizons not tested by drilling in discovered deposits, in which favourable geological and geophysical data suggest that the existence of reserves may be anticipated. 

Appraisal wells, drilled at the exploration stage within structures or other traps with an observed oil and gas content for the purpose of studying the geological structure of the deposit and the quality of the mineral to the extent necessary to permit confirmation of oil and natural gas reserves in categories which will serve as a basis for investment decisions, as well as obtaining data required for developing and exploiting the deposit. 

As a specific illustration reference may be drawn to molybdenum reserve scenario in the United States. The reserves are mainly grouped under five categories (i) primary, (ii) byproduct of copper ores, (iii) co-product of copper-molybdenum ores, (iv) by-product of tungsten ores, and (v) by-product of uranium ores. These have been presented and briefly elaborated in Table 1.14. It may finally be recorded by way of summary that the present day molybdenum sources in the world today seem to be principally of two main kinds first, the large-tonnage, low-grade, disseminated type of deposit in which molybdenite is the principal economic mineral second, the deposits in which molybdenite occurs as a by-product in... 

By-product of uranium ores The reserves belonging to this category consist mostly of the uraniferous lignites in North and South Dakota. 

Currently, protein microarrays can be divided into various types depending on the strategies to be chosen. For example, according to the array structure and shape, protein microarrays include 3D-surface structure [30, 31], nanowell [32], and plain chips [33-36], Meanwhile, considering the field of application, protein microarrays can be classified into five categories antibody array, antigen or reserve array, functional array, capture array, and solute array. Table 11.6 shows the differences among them. 

Most categories of port have a gender (such as input and output ) and a type of value that is transmitted, from simple numbers to complex objects such as reservations or stock dealings. These elements also are defined by the specific component architecture, which also must define the rules whereby the ports can be connected (for example, an input always to an output).
