450-5 m,u.)since it yielded a singleband on mixed chromatography with cryptoxanthin obtained from yellow maize (Sadana, 1946). Zone II. This was an orange-coloured band. The pigment was identified as neo-,-carotene U (maxima in light petroleum 480 and 450 mp.; Sadana, 1949). Zone III. This was reddish orange in colour. The pigment was extracted and identified as $-carotene by its absorption spe...

Cancers of the breast, cervix, uterus and ovary are the most prevalent cancers in women worldwide. Proteases play a key role in tumor cell invasion and metastasis by digesting the basement membrane and ECM components. Strong clinical and experimental evidence demonstrates association of elevated levels of urokinase plasminogen activators (u-PA) an...

BACKGROUND Band 5 tartrate-resistant acid phosphatase (TrACP; EC 3. 1.3.2) consists of two isoenzymes, bands 5a and 5b, of which band 5b TrACP is considered to be derived from bone. However, no kinetic method for the specific measurement of band 5b TrACP in serum is available. Our aim was to develop a kinetic assay method for the specific measurement of band 5b TrACP in serum. METHODS Band 5b...

Accurate computational predictions of band gaps are practical importance to the modeling and development semiconductor technologies, such as (opto)electronic devices photoelectrochemical cells. Among available electronic-structure methods, density-functional theory (DFT) with Hubbard U correction (DFT+U) applied edge states is a computationally tractable approach improve accuracy gap beyond tha...

This paper presents different slotted structures such as U-slot, half U-slot, half π-slot and π-slot to achieve the dual band characteristics of the antenna etched on a glass epoxy substrate (εr= 4.3) is suspended over the ground plane with an air gap for all slotted structures [1-2]. A comparative analysis has been made for the U and half U, π and half π designs are proposed by reducing area t...

This paper proposes an idea to modify the conventional Wilkinson power dividers to have physically spaced output ports. The well-known internal resistor of Wilkinson power divider is now connected to output ports by two additional transmission lines to create a triangular shape power divider. Several modified power dividers are designed at frequency of 1.0 GHz and one of them is fabricated and ...

We present deep u-, and g-band images taken with the MegaCam on the 3.6 m Canada-France-Hawaii Telescope (CFHT) to support the extragalactic component of the Spitzer First Look Survey (hereafter, FLS). In this paper we outline the observations, present source catalogs and characterize the completeness, reliability, astrometric accuracy and number counts of this dataset. In the central 1 deg2 re...
