In this work, we propose a simple method for obtaining the algebraic solution of a complex interval linear system where coefficient matrix is a complex matrix and the right-hand-side vector is a complex interval vector. We first use a complex interval version of the Doolittle decomposition method and then we restrict the Doolittle's solution, by complex limiting factors, to achieve a complex in...

this study investigated the effect of different harvesting techniques on the recovery rate and quality of bovine cumulus oocyte complexes (cocs) and their subsequent developmental competence including in vitro maturation, fertilization and blastocyst formation. the cocs were retrieved from slaughter ovaries using aspiration, slicing, or aspiration followed by slicing. the cocs were examined mic...

in this study a sensitive, simple and accurate spectrophotometric method was suggested for determination of tamsulosin in bulk powder and pharmaceutical dosage form based on the formation of an ion-pair complex between the drug and bromocresol green in a buffer solution at ph 3.5. the formed yellow color complex was extracted with chloroform and measured at 415 nm. the optimum reaction conditio...

in this investigation, cuins2 ternary compound was synthesized by injection of thiourea solution into a hot copper-indium solution. the cucl, incl3 along with (sc (nh2)2) were used as a precursor dissolved in high boiling point solvent such as oleylamine (ch(ch2)17nh2) and oleic acid (ch(ch2)16cooh) as a coordination solvent and capping agent, respectively. the size, distribution and shape were...

in this paper we show that expansion of a buchsbaum simplicial complex is $cm_t$, for an optimal integer $tgeq 1$. also, by imposing extra assumptions on a $cm_t$ simplicial complex, we provethat it can be obtained from a buchsbaum complex.

siilver tetrafluoroborate complex of 5.11.17.23-tetra-tert-butyl-25-26,27,28-tetrakis (diphenylphosphinoylmethoxy)calyx[4]arene (l) has been synthesized by reaction of silver tetrafluoroborate and l in dichloromethane at room temperature. the complex formed has a 1:1 metall/ligand ratio. 1h and 31p nmr data support an encapsulated structure of the complex in which silver ion is located inside t...

objective: antigen 85 complex of mycobacterium tuberculosis includes three immunogenic proteins which are important tb vaccine candidates. the use of these protein as a component of subunit vaccines, as a part of dna vaccines or recombinant bcg boosters, enhances their recombinant production. recombinant production of these mycobacterial proteins located in the cell wall somehow differs from th...

carney syndrome (cs) is an autosomal dominant multiple neoplasia syndrome that includes cardiac, endocrine, cutaneous, and neural tumors. cardiac myxomas can be seen in the course of cs. a 46-year-old female patient was admitted to our clinic with palpitation, cough, and exertional dyspnea. physical examination revealed pigmented lesions, especially scattered in the neck, chest, and extremities...

background: based on biochemical properties, enterobacter cloacae represents a large complex of at least 13 variant species, subspecies, and genotypes that progressively identified as the most species causing hospital-acquired infections. the aim of this study was to determine the relevance between phylogenetically related strains within the e. cloacae complex and the frequency of urinary tract...

background: culex pipiens complex shows variations in morphological and biological characters including differ­ent biological forms and has medical and veterinary importance. because of having morphological variations, some­times it is not easy to separate this species from cx. quinquefasciatus and cx. torrentium . the aim of this study was to   identify the   culex pipiens complex species in o...
