چکیده
In this paper, we improve the existence results for holey self-orthogonal Latin squares with orthogonal mates (HSOLSSOMs), especially for 6 il. We able to construct three new SOLSSOMs of orders 46, and existence of which is previously unknown.

Existence of HSOLSSOMs of type 4nu1
This paper investigates the existence of holey self-orthogonal Latin squares with a symmetric orthogonal mate of type 4u (briefly HSOLSSOM(4u)). For u > 0, the necessary conditions for existence of such an HSOLSSOM are (1) u must be even, and (2) u ≤ (4n−4)/3, and either (n, u) = (4, 4) or n ≥ 5. We show that these conditions are sufficient except possibly (1) for 36 cases with n ≤ 37, (2) for ...
متن کاملMolecular characterization of haemagglutinin-neuraminidase gene among virulent Newcastle disease viruses isolated in Iran
Background: Virulent Newcastle disease virus (vNDV) causes great economic losses to the poultry industry throughout the world. Despite the endemicity of Newcastle disease (ND) and occurrence of recurrent outbreaks, the nature and genetic features of circulating NDV strains in Iran are largely unknown. Aims: This study was conducted to characterize 13 NDV isolat...
متن کاملCytotoxic and apoptogenic effects of Bryonia aspera root extract against Hela and HN-5 cancer cell lines
Objective: Bryonia aspera (Stev. ex Ledeb) is a plant that grows in northeast of Iran. In the present study, cytotoxic and apoptogenic properties of B. aspera root extract was determined against HN-5(head and neck squamous cell carcinoma) and Hela (cervix adenocarcinoma) cell lines. Materials and Methods: HN-5 and Hela cell lines were cultured in DMEM medium and incubated with different concent...
متن کاملStudy of crocin & radiotherapy-induced cytotoxicity and apoptosis in the head and neck cancer (HN-5) cell line
Malignant tumors of head and neck carcinomas are the sixth most common type of cancer. Current systemic therapies for cancer show side effects in normal tissues and short-term efficacy due to drug resistance. Consequently, there is much interest in identifying new drugs for cancer treatment. Crocin (an active ingredient of saffron) has been shown to have cytotoxic effects on cancer cell lines. ...
متن کاملBIODESULFURIZATION OF SIMULATED LIGHT FUEL OIL BY A NATIVE ISOLATED BACTERIA BACILLUS CEREUS HN
In the present paper, the biodesulfurization of simulated light fuel oil (i.e., dibenzothiophene (DBT) in dodecane) and untreated kerosene with a high total sulfur content has been studied by a native isolated bacterium named Bacillus cereus HN. The influences of various parameters such as the reaction temperature (T), biocatalyst cell density, oil phase fraction (OFP), and initial DBT concentr...
