Abstract:

Purpose The purpose of this paper is to propose the parametric bootstrap method for valuation of over-the-counter derivative (OTCD) initial margin (IM) in the financial market with low outstanding notional amounts. That is, an aggregate outstanding gross notional amount of OTC derivative instruments not exceeding R20bn. Design/methodology/approach The OTCD market is assumed to have a Gaussian probability distribution with the mean and standard deviation parameters. The bootstrap value at risk model is applied as a risk measure that generates bootstrap initial margins (BIM). Findings The propos

Abstract:

ABSTRACTThe provision of graduated mortality rates, for the United Kingdom pensioners' experience, based on the so-called ‘amounts’ data sets is addressed. Specifically a methodology is investigated, building on the existing methods practiced by the CMI Bureau, which takes a more detailed account of the underlying structure of the data involved. The method is applied to the U.K. pensioners' experience and recent mortality trends in this experience revealed.

Abstract:

Unregulated use of antibiotics can lead to their accumulation in bee prod-ucts, in particular, in wax. The most effective methods of detecting residues of an-tibiotics in wax are the analytic test system "Charm-2", which is based on the RIA method. Experimental data testify its suitability and prospects for wide practical use in the bee wax safety control system. The sensitivity of the method to the anti-biotic oxytetracycline is 20 μg/kg with confidence of 95%.

Abstract An LC method using a new cleanup technique was compared with 2 microbiological methods for determining small amounts of niacin in vinegar.

Among the 3 methods, titrimetry was the most precise. The turbidimetric method tended to yield greater positive error than the titrimetric method. On the other hand, the titrimetric method requires a longer incubation period (72 h) than the tu

The expectation and variance of the amount of linkage disequilibrium are also obtained. Gene conversion generates positive linkage disequilibrium and the degree of linkag

Records from meteorological observers indicate that clear days (0–1 octa) represent the most frequent cloud amount for low clouds. In contrast, the total cloud amount is more aleatory.

Abstract:

This study compares two confirmatory factor analysis methods on their ability to verify whether correct assignments of items to subtests are supported by the data. The confirmatory common factor (CCF) method is used most often and defines nonzero loadings so that they correspond to the assignment of items to subtests. Another method is the oblique multiple group (OMG) method, which defines subtests as unweighted sums of the scores on all items assigned to the subtest, and (corrected) correlations are used to verify the assignment. A simulation study compares both methods, accounting for the in

Abstract:

A method named “bag culture” was developed for coculturing of Linum persicum (section Syllinum) and L. austriacum (section Linum) hairy roots. For this propose L. austriacum and L. persicum hairy root cultures were established using Agrobacterium rhizogenes in McCown medium. L. persicum hairy roots in bags (1 mm2 mesh) were successfully grown together with L. austriacum hairy roots. The amounts of podophyllotoxin (PTOX) and 6-methoxypodophyllotoxin (MPTOX) produced by L. persicum hairy root cultures were detected using HPLC. The results indicated that the amounts of both lignans and growth ind

Abstract:

The article is devoted to methods for determining the residual amounts of antibiotics in mariculture products, namely in shrimp. The use of antibiotics by shrimp producers to reduce microbiological indicators and increase the shelf life of shrimp makes it relevant to determine the maximum permissible level of residual amounts of antibiotics during monitoring and certification tests of these products. A promising method is the immunomicrochip technology, with the help of which it is possible to conduct simultaneous qualitative and quantitative analysis of several analytes in one sample. This me

We investigated the carboxylation of graphene oxide using chloroacetic acid and different amounts of NaOH. Increase of carboxyl groups was observed only at high amounts of NaOH, but partial reduction attenuates the yield of further functionalization.

We developed a device for automatic closed friction and analyzed its test results in this paper, which showed the influence factors in the test methods of textile negative ion occurrence amounts. The textile negative ion occurrence amounts in different time stages were tested in this process; the analysis of its influence of temperature and humidity has certain reference significance for improving testing device for testing textile negative ion concentration, on the basis, functional textiles were also studied. Finally, we put forward the influence factors in the test methods of textile negati

Abstract:

Psychophysical tuning curves were generated by normally hearing and hearing-impaired subjects using two methods; a detailed laboratory method and a Bekesy method proposed as suitable for clinical use. The two methods were compared for stability, the amount of masking produced and the pattern of the masking functions. The two measures of frequency resolution were found to be equally reliable and showed the same range of repeatability as simple pure tone thresholds. The patterns of the masking functions were similar regardless of the method used. However, the absolute amounts of masking indicate

Introduction. Thanks to possessing beneficial properties and vitamin content, citrus fruits occupy a prominent place in the ubiquitous nutrition of all ages due to various crops. On the other hand, due to climatic conditions, they cannot be cultivated in our country and are classified as imported products, which justifies the importance of controlling their safety. Purpose of the work. The creation of a multicomponent method for determining the residual amounts of pesticides and their metabolites in citrus fruits. Materials and methods.
