In this paper, we introduce a high-speed and low power Phase-Frequency Detector (PFD) that is designed using modified TSPC (True Single-Phase Clock) positive edge triggered D flip-flop. This PFD has a simpler structure with using only 19 transistors. The operation range of this PFD is over 1.2Ghz without additional prescaler circuits. Furthermore, the PFD(More)
Effects of a supplemental fermented agro by-products diet on growth performance, blood characteristics and carcass traits were investigated in fattening pigs. The fermented diet mainly contained 38.0% brewer’s grain, 25.0% rice bran and 21.0% byproduct of king oyster mushrooms. The mixed ingredients were fermented at 40°C for 7 days and fed to crossbred(More)
Naringenin has been shown to display various biological effects such as antioxidant, anticancer, anti-inflammatory, and antiviral activities. Taxifolin inhibits the production of lipopolysaccharide-induced prostaglandin E, and fustin suppresses the activity of acetylcholinesterase. They all belong to flavanone(More)
A phytotoxic root exudate from Acroptilon repens was identified as 7,8-benzoflavone, an inhibitor of cytochrome P450 1A2 and activator of cytochrome P450 3A4. The synthetic 5,6-benzoflavone also is a potent phytotoxin. Six 7,8-benzoflavones and eight 5,6-benzoflavones were synthesized in this study. The NMR data for a few of these compounds have been(More)
Aryl diketoacid (ADK) is well known for antiviral activity which can be enhanced by introduction of an aromatic arylmethyl substituent. A natural flavonoid quercetin has a 3,5-dihydroxychromone pharmacophore which is in bioisosteric relationship with the 1,3-diketoacid moiety of the ADK. Thus, it was of our interest to test the antiviral activity of the(More)
The aim of the present study was to investigate the effect of Eucommia ulmoides leaf (EUL) supplementation on the growth performance, blood and meat quality parameters in growing and finishing pigs. Ninety gilts (L x LW x D, 20 kg initialBW) were housed 10 per pen in a front-open building with three replicate pens per treatment. Experimental treatment was(More)
The objective of the present study was to investigate the effect of fermented apple diet (FAD) supplementation on the growth performance and meat quality in finishing Berkshires. The FAD was made from dropped apple mixed with rice bran and barley bran. Until 81 +/- 1 kg live weight at 133 +/- 1 days, the animals were fed a growing diet, after which(More)
Objective Fusarium mycotoxins deoxynivalenol (DON) and zearalenone (ZEN), common contaminants in the feed of farm animals, cause immune function impairment and organ inflammation. Consequently, the main objective of this study was to elucidate DON and ZEN effects on the mRNA expression of pro-inflammatory cytokines and other immune related genes in the(More)
In this paper the Design and Verification of High performance PLL is presented and implemented at 180nm CMOS Process Technology. Process and Temperature Compensation Techniques for minimizing the variation of the free-running frequency of Voltage Controlled Oscillator are discussed. Matched up and down currents Charge Pump is designed. 2 types of PFDs are(More)
The objective of the present study was to investigate the effects of corn dried distiller's grains with solubles (DDGS) and enzyme premix (mannanase + phytase) supplementation on the growth performance, carcass and meat quality parameters in finishing pigs. Sixty hybrid pigs (L × LW × D) with initial weight of 63.92 ± 1.50 kg were used in a 3 × 2 factorial(More)
