A cold rolled and heat treated steel sheet is provided. The steel sheet includes a composition including 0.17%≤carbon≤0.24%, 1.9%≤manganese≤2.2%, 0.5%≤aluminum≤1.2%, 0.5%≤silicon≤1%, Si+Al≥1.3%, 0.05%≤chromium≤0.2%, 0.015%≤niobium≤0.03%, sulphur≤0.003%, phosphorus≤0.03% and optionally 0.005%≤titanium≤0.05%, 0.001%≤molybdenum≤0.05%, a remainder of the composition including iron and the unavoidable impurities. A microstructure of the coated steel sheet includes, in area fraction, 10 to 20% residual austenite, said austenite phase having a carbon content between 0.9 to 1.1%, 40 to 55% polygonal ferrite, 15 to 40% granular bainite and at least 5% tempered martensite, a sum of tempered martensite and residual austenite being between 20 to 30%. A method is also provided.

A method of manufacturing an object is disclosed. In some aspects, the method includes selectively heating an initial layer of a composition, including elements of a granular material coated with a metallic material. The method further includes selectively heating an additional layer of the composition, disposed in contact with the initial layer, the selective heating of each respective layer to the threshold temperature actuating an exothermic reaction between the elements of the granular material and the metallic material coating associated therewith to form a molten portion of the respective layer, with turbulence in the molten portion of the respective layer disrupting oxidation of the molten granular material and promoting formation of an intermetallic compound in the molten portion of the respective layer upon cooling thereof below the threshold temperature, and with the portions of the respective layers combining to form the object.

A granulation composition having the granulation properties improved without being affected by the content, type or nature of a pesticidal active ingredient, and a process for its production, are provided. <??>A granular composition which comprises a pesticidal active ingredient and a highly pure quartz powder as essential components and which is obtained by an extrusion granulation method. A process for producing the granular composition, which comprises blending a pesticidal active ingredient and a highly pure quartz powder as essential components, and granulation by an extrusion granulation method. As compared with conventional ones, the granulation properties can be improved without being affected by the content, type and nature of the pesticidal active ingredient or the prescribed grain diameter of the granular composition.

A method is defined for determining whether a rock is capable of functioning as an oil reservoir has had or presently contains oil. The method includes the steps of: -cleaning a sample of the rock in a manner such that at least some of any adsorbed oil on the rock will remain and any oil inclusions within the rock remain intact; -irradiating the cleaned sample with fluorescence inducing electromagnetic (typically UV) radiation and measuring emitted (typically UV and visible) radiation from the sample; and-comparing the emitted radiation measurement against a similarly determined measurement from a rock sample of a known oil-producing reservoir, to determine whether or not the rock has had or presently contains oil. In a variation of the above method, the sample of the rock is cleaned step-wise in a manner that removes other than adsorbed oil on the rock, with a final cleaning step including contacting the sample with a solvent into which some adsorbed oil may be extracted. The solvent extract can then be analysed for oil (typically by irradiating the solvent with fluorescence inducing electromagnetic (typically UV) radiation) and the analysed oil then compared against a similarly derived and analysed oil from a rock sample of a known oil reservoir to determine whether or not the rock has had or presently contains oil. Typically the rock is granular and typically the cleaning step involves disaggregating the rock into single grains, prior to cleaning.

The present invention relates to a transfer chute (100) for granular material, comprising a chute body defining a flow pathway (120) for granular material, a raised portion (110) having an inclined surface (111), and a splitter member (130) arranged proximal to the raised portion (110) for, in use, dividing a flow of granular material over the raised portion into first portion in first conduit (100) and a second portion in a second conduit (300). In some embodiments, a channel (150) is disposed between the first and second conduits (100; 300) to transpose a vertical arrangement of first and second portions of granular material within the chute (10). In this way, separation by particle size or density in the flow may be reversed.
