growing demands and requires of high data rate systems cause significant increase of high frequency systems for wideband communication applications. as mixers are one of the main blocks of each receivers and its performance has great impact on receiver’s performance; in this thesis, a new solution for ku-band (12-18 ghz) mixer design in tsmc 0.18 µm is presented. this mixer has high linearity a...
The effects of Trigonella foenum graecum (TF) and Foeniculum vulgare (FV) seeds powder on antimicro-bial activity and performance of broiler chickens were studied. Based on a completely randomized design, 240 broiler chicks (Ross 308) were assigned to 4 treatments and 4 replicates. The treatments were a basal diet (control, T 1), T 1 plus 0.5% TF (T 2), T 1 plus 0.5% FV (T 3) and TFFV (0.25% TF...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
to determine the effects of pre-germinating of tubers and plant density on yield and some agronomic traits of six commercial potato cultivars, an experiment was carried out in ardebil agricultural research station for two years (2001 and 2002). the experiment was in a split split splot on the basis of completely randomized block design with three replications. pre-germination and non pre-germin...
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
effect of intermittent mash-pellet feeding programs on broilers performance, ascites susceptibility and economic yield was studied using 480 broilers in six treatments and five replicates of 16 chicks per pen were used in a completely randomized design. treatments including: 1. mash feed, 2. heated-mash feed, 3. mash feed in starter and grower and pellet feed in finisher, 4. mash feed in starte...
the effect of perlite different amounts on grain yield and water use efficiency in winter wheat (cultivar of zarrin) in ghorveh (kermanshah province), was studied in 2007-2008. field experiment using completely randomized block design with seven treatments (p0, p1, p2, p3, p4, p5 and p6) including: zero (reference), 75, 150, 300, 600, 1200 and 2400 kg.ha-1 with four replicates was conducted. ir...
effect of using l–threonine and reducing dietary levels of crude protein on egg production in layers
this experiment was conducted to determine the effect of using l-threonine and reducing dietary levels of crude protein (cp) on egg production criteria in layers. three hundred of hy-line w36 laying hens were used in this experiment. this experiment consisted of three experimental treatments with five replications in each. experimental treatments included 3 diets with different levels of cp whi...
effect of l-carnitine and butyric acid on the performance and immune responses of 192 broiler chickens (ross 308) was investigated with three levels of l-carnitine (zero, 125 and 250 mg/kg) and two levels of butyric acid (2 g/kg) in a 2×3 factorial arrangement based on randomized complete block design with 6 dietary treatments, four replicates and eight birds per each. broilers fed basal diet p...
the aim of this experiment was to study the effects of hydrochloric and butyric acids addition to broiler diets on performance, carcass characteristics, intestinal microbial population and intestinal histology. two hundred eighty ross 308 one-day old female broiler chicks were assigned to 7 dietary treatments and 4 replicates of 10 chicks in a completely randomized design. experimental treatmen...
