To a dried extract Containing hippuric acid (HA), 1.0 mL of acetic anhydride and 2.0 mL of 0.5% p-dlmethyiamlnobenzaldehyde (DAB) solution In pyridine were added, and the solution was kept at 40 O C for 1 h after thorough mlxing. The absorbance was then determlned at 458 nm agalnst a blank containing acetic anhydride, DAB, and pyridine. This method was in good agreement with Beer’s law within 1...

The digital transition of analog TV is rapidly taking place throughout the world. However, the digital transition of radio is progressing at a slower rate. Diverse standards are being considered for adoption and different countries have different frequencies allocated for digital radio. As a consequence, the progress in the development of digital radio receiver chipsets has been rather stagnant...

There are typographical errors in the published article. There are three instances in the article that refer to “26S rRNAs”. This is incorrect. The correct text is “28S rRNAs”. In the Abstract, “26oC” is incorrect. The celcius degree sign should be superscripted to read: “26°C”. In the Fig. 1 legend, the following text has a typographical error: "Positive cells are brown (DAB) and the backgroun...

A power conversion system needs high efficiency for modern-day applications. DC–DC isolated bidirectional dual active bridge-based converter promises and reliability. There are several topologies available in the market claiming to be best of their type, so it is essential choose from them based on possible result operation a variety As result, this article examines characteristics, functionali...

Italian ryegrass (Lolium multiflorum Lam.) is a weed broadly found in fields cultivated with wheat and barley crops. Seed inputs into the soil before harvesting winter crops increase seed bank, ensuring survival. This study evaluated persistence of seeds subjected to burial depths over time. Experiments were carried out field for two years randomized block experimental design four repetitions. ...

The production of H2O2 by cells in cold paraformaldehyde-fixed frozen sections of inflammatory lesions was histochemically demonstrated by incubating them with diaminobenzidine (DAB) for 2 to 6 h. Catalase (150 micrograms/ml, about 1400 U/ml) inhibited the reaction, indicating that H2O2 was required to produce the chromogenic DAB product. Granulocytes (PMNs and eosinophils) were the main types ...

This paper presents the field trial results of digital audio broadcasting (DAB), DAB+ and terrestrial-digital multimedia broadcasting (TDMB) audio systems to provide useful information about each digital radio broadcasting standard. Although the all methods are representative digital radio broadcasting standards based on Eureka-147, they have different parts from each other. This field trial re...

Technical investigations suggest that DRM+ is a suitable candidate for the transition from analogue FM to digital broadcasting in VHF band II (87.5 108.0 MHz) in Europe [2]. Unfortunately, there are mainly three major problems to solve: 1. VHF band II is historically defined for the use of analogue FM sound broadcasting, and, it is – as such – extensively used in Europe; 2. the lack of agreed c...

DAB (Digital Audio Broadcasting) is a the European successor of FM radio and it can broadcast besides audio services also other services such as traffic information. In this paper the probability of non-recognized errors in the system is derived for a 8 kbit/s data subchannel using protection level EEP3-A. This is important as data services rely on error-free transmission. It has been shown tha...
