objective: this study designed to test the antibacterial potency of enrofloxacin (enr) and essential oils from zataria multiflora boiss (zeo) and trachyspermum copticum (teo)on aeromonas hydrophila. material and methods: the antibacterial potency of test compounds was determined by several methods including the inhibition zone diameter determination, microbroth dilution method and colorimetric ...

A 3-level schema architecture is proposed to address some inadequacies in recent object-oriented data models. The conceptual schema is based on a normal form object-oriented entityrelationship IOOER) diagram. A set of mapping rules is defined that allows 00 externalschemas, based on the 02 data model, to be generated from the conceptual schema. Similar mapping rules can be defined to generate e...

Studies have shown that the performance of speech recognition algorithms severely degrade due to the presence of task and emotional induced stress in adverse conditions. This paper addresses the problem of detecting the presence of stress in speech by analyzing nonlinear feature characteristics in specific frequency bands. The framework of the previously derived Teager Energy Operator(TEO) base...

An algorithm based on the ability of TEO to track the changes in the envelope of ECG signal is proposed for identifying PVCs in ECG. Teager energy is calculated from DCT coefficients of ECG signal. This method can be considered as computationally efficient algorithm when compared with the well-known DCT cepstrum technique. EPE is derived from the teager energy of DCT coefficients in DCT-TEO met...

The Engineering and Fabrication Branch, TEO, occupies the first three floors of the Steven Muller Center for Advanced Technology at APL. The first floor i dedicated to microelectronic , the second houses the conventional electronic fabrication faci lities and the Materials Laboratory, and the third is home to the Engineering Design (TED) and Engineering Design Automation (TEA ) Groups. The TEA ...

This study was conducted to evaluate the effects of dietary inclusion of thyme essential oil (TEO) on growth performance and immune responses of broiler chicks subjected to heat stress (HS). Broilers were divided into five groups; group 1) chicks fed with basal diet and reared under thermoneutral condition; group 2) chicks fed with basal diet and subjected to HS condition; and groups 3, 4 and 5...

The current study aimed to investigate the chemical composition and the synergistic potential of two essential oils (EOs), as obtained from Salvia officinalis L. (SEO), and Thymus vulgaris L. (TEO). The antifungal potential was tested in vitro against Fusarium graminearum (Fg 06_17), the herbicidal effect was studied using weed seeds of Amaranthus retroflexus (ARET), Chenopodium album (CALB), E...

Salmonella Typhimurium (S. Typhi) and Escherichia coli (E. coli) have been responsible for an increasing number of outbreaks linked to fresh produce, such as baby spinach leaves, in the last two decades. More recently, antimicrobial biodegradable packaging systems have been attracting much attention in the food packaging industry as eco-friendly alternatives to conventional plastic packaging. T...

Pb(6)Co(9)(TeO(6))(5), hexa-lead(II) nona-cobalt(II) penta-tellur-ate(VI), is isotypic with its nickel(II) analogue. The asymmetric unit contains two Pb atoms (site symmetries .2., ..2), four Co atoms (..2, ..2, 3.., 3.2) two Te atoms (..2, 3..) and six O atoms (all in general positions), with the Te and Co sites in octa-hedral coordination environments. The crystal structure can be subdivided ...

Abstract The current study aimed to investigate the efficacy of dietary thyme essential oil (TEO), Nigella sativa (NSEO), nano-emulsion (TEO-NE), and (NSEO-NE) in reducing total ammonia nitrogen (TAN), improving immune response, mitigating stress, acting as anti-inflammatory agents well preventing streptococcosis infection Oreochromis niloticus ( O. niloticus) . Fish N = 330, 14 ± 2 g) were div...
