The random nature of transgene integration harbours various pitfalls for development of production cell lines including clonal variation in expression level and growth characteristics. The CEMAX system is an expression system for targeted integration of expression cassettes via DNA double-strand break induced homologous recombination. Stable high producers are available within 4 weeks without t...

Two cubical 3D electric circuits with single and double capacitors twelve ohmic resistors are considered. The the sides of cube. circuit is fed a internal emf. charge on capacitor(s) current distributions all circuit(s) vs. time evaluated. analysis requires solving differential-algebraic intertwined symbolic equations. This accomplished by applying Computer Algebra System (CAS), specifically Ma...

An experiment was conducted to evaluate the effect of dietary content and combinations of Zn, Fe, and Cu on deposition of these elements in egg components, liver, and excreta. Excreta were applied as a manure to a lawn, and 3 mo later soil and herbage samples were taken and analyzed. The experiment comprised 144 hens in 8 groups. The basal diet contained Zn, Fe, and Cu at 63.4, 92.8, and 9.0 mg...

In this paper two linear arrays including a linear 1×4 and a planar 2×2 of microstrip patch and half-mode substrate integrated waveguide (SIW) cavity hybrid antenna are introduced and investigated. These are simply implemented using low cost single layer printed circuit board (PCB) process. The array element consists of a rectangular microstrip patch with appropriate dimensions in the vicinity ...

Before making a comparison of grass-fed vs. grainfed beef it is necessary to first define these two beef types. An animal is considered grass-fed, according to the USDA Grass Fed Marketing Claim Standards, when grass and forage are the “feed source consumed for the lifetime of the ruminant animal, with the exception of milk consumed prior to weaning. Animals cannot be fed grain or grain by-prod...

Until now, there have been various studies concerning bottle-fed and breast-fed children. Prevalence of allergic manifestations like eczema and asthma among bottle-fed children is much higher than healthy controls. In this study, we found that respiratory infection for breast-fed children was 3.1%, whereas in bottle-fed children it was 25.1%for gut disorders, 9.2% in breast-fed vs.13.1 % f...

introduction: this study aimed to assess the incidence of breastfeeding-associated hypernatremia and related risk factors among hospitalized hyperbilirubinemic neonates. methods: this prospective study was conducted at nemazee hospital affiliated to shiraz university of medical sciences during one year to determine the association between hypernatremia (serum sodium concentration of >150 meq/l)...

In order to use the “Trinidad de Guedes" phosphorite (TGP) as a supplement of calcium and phosphorus in animals, its concentrations of heavy metals were determined and their deposition was analyzed in broilers. Toxic elements were determined using atomic absorption spectrophotometry. The mean levels of heavy metals found in TGP were 82.5 mg/kg lead (Pb), 7.2 mg/kg cadmium (Cd), 1056.9 mg/kg man...

in this paper we study right $n$-engel group elements‎. ‎by modifying a group constructed by newman and nickel‎, ‎we construct‎, ‎for each integer $ngeq 5$‎, ‎a 2-generator group $g =langle a‎, ‎brangle$ with the property that $b$ is a right $n$-engel‎ ‎element but where $[b^k,_n a]$ is of infinite order when $knotin {0‎, ‎1}$‎.
