Edges are instant change in intensity value of pixels in the digital image. Image edge detection converts original image in to binary image. This binary image contains information about edges of digital image. Recently Ant Colony Optimization Meta-heuristic algorithm is used for the image edge detection. Ant colony optimization algorithm is inspired from the behaviour of real ants. From this ACO based algorithm we get pheromone matrix at end, which contains the information about edge pixels of original image. Discrete wavelet transform is used to decompose original image in for sub-bands. ACO algorithm is separately applied on that four sub-bands and reconstructed image of these four components give better result than single ACO edge detected image. Dual tree complex wavelet transform is advance than discrete wavelet transform. Problems in DWT like overemphasized, distortion and less visible image are removed using DT-CWT with ACO algorithm. It has higher orientation property. K-means clustering algorithm and Fuzzy C-means algorithms are used to decide whether pixels in image are edge or not. So that proposed algorithms which are ACO + DT-CWT with K-means clustering algorithm and Fuzzy C-means algorithm, they are able to find all possible edges from image and give better result compared to other edge detection algorithms. © 2016 IEEE.

A new, rapid, precise, accurate and sensitive first derivative spectrophotometric analytical method is proposed for the simultaneous estimation of Pantoprazole and Cinitapride in combined dosage form. The drugs obeyed the Beer's law in the concentration range of 1-26 ug/ml. In the proposed method, absorbance was measured at 302 nm (Zero Crossing Point of Cinitapride) and 249 nm (Zero Crossing Point of Pantoprazole). Accuracy of the method was determined by recovery studies and was found to be 100.35±0.18 and 99.61±0.17 for Pantoprazole and Cinitapride respectively. The proposed method is simple, accurate, precise, rapid and cost effective. Therefore the proposed method can be used for routine analysis of both drugs in bulk as well as in pharmaceutical formulations.

Herbs have been used in medicines and cosmetics from centuries. Their potential to treat different skin diseases, to adorn and improve the skin appearance is well-known. As ultraviolet (UV) radiation can cause sunburns, wrinkles, lower immunity against infections, premature aging, and cancer, there is permanent need for protection from UV radiation and prevention from their side effects. Herbs and herbal preparations have a high potential due to their antioxidant activity, primarily. Antioxidants such as vitamins (vitamin C, vitamin E), flavonoids, and phenolic acids play the main role in fighting against free radical species that are the main cause of numerous negative skin changes. Although isolated plant compounds have a high potential in protection of the skin, whole herbs extracts showed better potential due to their complex composition. Many studies showed that green and black tea (polyphenols) ameliorate adverse skin reactions following UV exposure. The gel from aloe is believed to stimulate skin and assist in new cell growth. Spectrophotometer testing indicates that as a concentrated extract of Krameria triandra it absorbs 25 to 30% of the amount of UV radiation typically absorbed by octyl methoxycinnamate. Sesame oil resists 30% of UV rays, while coconut, peanut, olive, and cottonseed oils block out about 20%. A "sclerojuglonic" compound which is forming from naphthoquinone and keratin is the reaction product that provides UV protection. Traditional use of plant in medication or beautification is the basis for researches and making new trends in cosmetics. This review covers all essential aspects of potential of herbs as radioprotective agents and its future prospects.

The present manuscript describes simple, sensitive, rapid, accurate, precise and economic dual wavelength spectrophotometric method for simultaneous determination of metoprolol succinate and olmesartan medoxomil in combined tablet dosage form. The utility of dual wavelength data processing program is its ability to calculate unknown concentration of components of interest in a mixture containing an interfering component. The principle for dual wavelength method is "the absorbance difference between two points on the mixture spectra is directly proportional to the concentration of the component of interest". The wavelengths selected for determination of metoprolol succinate were 225.2 nm and 258.2 nm, whereas the wavelengths selected for determination of olmesartan medoxomil were 211 nm and 229.8 nm. The two drugs follow Beer-Lambert's law over the concentration range of 5-30 μg/ml. The method was successfully applied to pharmaceutical dosage form because no interference from the tablet excipients was found. The results of analysis have been validated statistically and by recovery studies.

M-commerce is the next generation of today's PC-based wired, e-commerce technology. The evolving success of mobile communication is transforming e-commerce into m-commerce. Users as a group of mobile devices are considered as a large potential market. Mobile commerce is any transaction involving the transfer of ownership or rights to use goods and services which is initiated and/or completed by using mobile access to computer-mediated networks with the help of an electronic device. Things are more complex when one or more operators are involved. There can be the case where the consumer and the merchant have accounts in different banks. Credit card or debit card information is stored in the mobile phone, so hackers can interpret it and use it for malicious purposes. The mobile operator will ask the consumer for his mobile personal identification number (MPIN). After verification of the MPIN, the mobile operator will verify the consumer's bank information.

With the advent internet in the 1990s to the present day facilities of ubiquitous computing, the internet has changed the computing world in a drastic way. It has traveled from the concept of parallel computing to distributed computing to grid computing and recently to cloud computing. Although the idea of cloud computing has been around for quite some time, it is an emerging field of computer science. Cloud computing can be defined as a computing environment where computing needs by one party can be outsourced to another party and when need be arise to use the computing power or resources like database or emails, they can access them via internet. Cloud computing is a recent trend in IT that moves computing and data away from desktop and portable PCs into large data centers. The main advantage of cloud computing is that customers do not have to pay for infrastructure, its installation, required man power to handle such infrastructure and maintenance. In this paper we will discuss what makes all this possible, what is the architectural design of cloud computing and its applications. © 2012 IEEE.

Synthesis of novel quinazolinone derivatives was performed from the reaction of N-benzoyl substituted piperazine-1-carbothioamide with 2-chloromethyl quinazolinone derivatives and screened for their in vitro cytotoxic activity by MTT assay. The cell lines used were NCI (human lung cancer cell), MCF 7 (Breast cancer cell), and HEK 293 (Normal epidermal kidney cell). Result of screening on cell line showed moderate to good anticancer activity for all the compounds. Compound 3d (IC50 = 1.1 ± 0.03 μM) was found to be the most active compared to standard methotrexate (IC50 = 2.20 ± 0.18 μM) and 5-florouracil (IC50 = 2.30 ± 0.49 μM). Structure activity relationship of synthesized analogs suggested that the presence of NH linker with aryl moiety at the third position of quinazolinone ring was important for potent anticancer activity. Electron donating group on phenyl ring at the third position of quinazolinone ring gave better anticancer activity then unsubstituted phenyl and electron withdrawing group. Activity by substituted piperazine at 2nd position of thiazole linked with quinazolinone scaffold gave better activity in the order of H > CH 3 > CO-C6H5. Our findings may impart new direction to medicinal chemists and biochemists for further investigations of quinazolinone-thiazole containing anticancer agents. © 2012 Springer Science+Business Media New York.

The described method was linear over the range of 0.5-6.0 μg/ml and 0.5-8.0 μg/ml for Enalapril maleate and Amlodipine besylate, respectively. The mean recovery was found to be 100.06± 0.49 % and 99.98± 0.63 % for Enalapril maleate and Amlodipine besylate, respectively. The intermediate precision data obtained under different experimental setup, the calculated value of coefficient of variation (CV, %) was found to be less than critical value. The proposed method can be useful in the quality control of bulk manufacturing and pharmaceutical dosage forms.

A simple, sensitive and precise RP-HPLC-DAD method was developed and validated for the determination of olmesartan medoxomil (AT-II receptor blocker) in the presence of its degradation products. Olmesartan medoxomil and all the degradation products were resolved on a C18 column with the mobile phase composed of methanol, acetonitrile and water (60:15:25, V/V/V, pH 3.5 by orthophosphoric acid) at 260 nm using a photodiode array detector. The method was linear over the concentration range of 1-18 μg mL-1 and precise with RSD < 1 % in intra- and inter-day study. Excellent recoveries of 99.3 ± 0.9 to 100.8 ± 1.2% proved the accuracy of the method. Developed method was specific, as indicated by chromatographic resolution > 2.0 for each peak and sensitive with LOD 0.03 μg mL-1 and LOQ 0.1 μg mL-1. The method was used to study the drug degradation behavior under forced conditions. Four degradation products (DP-I, II, III, IV) were formed during the degradation study in 0.1 mol L-1 HCl whereas only DP-I, II and III were formed in water, 0.01 mol L-1 NaOH and 3% H2O2. No significant thermal or photolytic degradation was observed in solid drug. The method was applied successfully for the assay of olmesartan medoxomil in the tablet dosage form.
