The toric residue is a map depending on n + 1 semi-ample divisors on a complete toric variety of dimension n . It appears in a variety of contexts such as sparse polynomial systems, mirror symmetry, and GKZ hypergeometric functions. In this paper we investigate the problem of finding an explicit element whose toric residue is equal to one. Such an element is shown to exist if and only if the as...
It is shown that the extended quadratic residue code of length 20 over GF(7) is a unique self-dual [20, 10, 9] code C such that the lattice obtained from C by Construction A is isomorphic to the 20-dimensional unimodular lattice D 20, up to equivalence. This is done by converting the classification of such self-dual codes to that of skew-Hadamard matrices of order 20.
The largest minimum weight of a self-dual doubly-even binary (n, k, d) code is d = 4bn/24c+ 4. Of such codes with length divisible by 24, the Golay Code is the only (24, 12, 8) code, the Extended Quadratic Residue Code is the only known (48, 24, 12) code, and there is no known (72, 36, 16) code. One may partition the search for a (48, 24, 12) self-dual doubly-even code into 3 cases. A previous ...
Background: Sub-clinical mastitis is an inflammation of mammary glands which is a big economic damage. Treatment of this disease isn’t recommended due to antibiotic residue in milk. Objective: In this study, clinical efficacy of - Zataria multiflora Boiss essential oil (ZMBeo) in treatment of sub-clinical mastitis was evaluated and other expedients were prepared. Methods: Thirty Holsteins cow...
In The Netherlands, all antibiotic treatments should be registered at the farm and in a central database. To enforce correct antibiotic use and registration, and to enforce prudent use of antibiotics, there is a need for methods that are able to detect antibiotic treatments. Ideally, such a method is able to detect antibiotic applications during the entire lifespan of an animal, including treat...
The isolation of prumycin from cultured broths of Streptomyces kagawaensis has been reported by HATA et al.') It inhibits the growth of some bacteria and fungi,') and shows antitumor action.') The structure determined by OMURA et al.3,4) to be 4-D-alanylamino-2-amino-2,4-dideoxy-Larabinose. We isolated this antibiotic from cultured broths of a strain BMG366-UF5 which was isolated from a soil sa...

Abuse of antibiotics is more common in developing countries. This study was undertaken to investigate the presence ciprofloxacin residue broiler tissues and effects misuse on hematological parameters broilers. Day old chicks (DOC) were collected reared up 31 days. The treatment started from 16th day until sacrifice. On 14th, randomly divided into three groups namely control group (group A), dis...
The thiazolylpeptides are a family of >50 bactericidal antibiotics that block the initial steps of bacterial protein synthesis. Here, we report a biosynthetic gene cluster for thiocillin and establish that it, and by extension the whole class, is ribosomally synthesized. Remarkably, the C-terminal 14 residues of a 52-residue peptide precursor undergo 13 posttranslational modifications to give r...
