The main criterion for the performance of welds is the strength. The least durable are the corner joints used to perform various types of welded joints. In the literature, the methods of calculating the strength of welded joints with solid seams are considered in sufficient detail. Methods of calculation of connection interrupted sutures absent. In this case, the greatest difficulty is the calculation of connections using circular intermittent seams, which are often performed in welded drums and pulleys. They work on torsion. Therefore, the development of methods for calculating circular intermittent seams for torsion is quite important. Shear stresses in welds from torque are determined depending on the value of the polar moment of resistance of its dangerous section. When determining the polar moment of resistance of the dangerous section of a circular discontinuous seam, it was represented by a set of sections in the form of a sector of a circular ring. The method of calculation of the polar moment of resistance of the rotated dangerous section of a circular discontinuous weld, which takes into account the relative length of the weld areas and their number, is proposed, as well as the method of accurate and approximate calculation of shear stresses in the weld.

Abstract: The rapid development of the number of islamic banks should be balanced with the availability of infrastructure to carry out daily operational practices. The operational tools include hardware as like as representative office, computerized system, reliable human resources and software as like as method, culture and financial and islamic banking knowledge. In terms of development of Islamic finance is the paper "Alternative Calculation of Return Shahibul Mal on Mudharabah Scheme on Bank Syariah" was written. During this calculation of return shahibul mal has not been standardized in a formula, thus causing two serious effects. First, in the theoretical level, the formula has not yet created a difficulty. Secondly, in practical level, the formula is not impressive enough to recalculate the complexity of return calculations obtained by shahibul mall, causing laziness of the community using the services of islamic bank. This paper using mathematical and arithmetic equations with the help of modeling made by the author to refine and improve the method of calculation that has been available. The purpose of this paper is to create a standard formula that facilitates the calculation of return earned by a shahibul mal in a mudaraba scheme in a islamic bank.

Underground spaces in town centres present a big attraction for investors. However, they put special requirements to the internal environment. Those requirements can be fulfilled by means of daylighting. Examples of lighting of underground spaces are discussed. It is shown that the common systems of natural lighting are not always possible to use and cause big heat losses. Hollow light guide pipes allow avoid the shortcomings of common daylight systems. Method of calculation of daylight factors from hollow light guide pipes is shown. The results of calculation of daylight factors under the light guide pipes of different diameters in the different depths are presented.
