Service Recommendation System using Social User’s Rating Behaviors

The research communities of information retrieval, machine learning and data mining are recently started to paying attention towards Service recommendation systems. Traditional service recommendation algorithms are often based on batch machine learning methods which are having certain critical limitations, e.g., mostly systems are so costly also new user needs to pay the certain cost for new login, can’t capture the changes of user preferences over time. So that to overcome from that problem it is important to make service recommendation system more flexible for real world online applications where data arrives sequentially and user preferences may change randomly and dynamically. This system present a new website of online social recommendation on the basis of online graph regularized user preference learning (OGRPL), which incorporates both collaborative user-services relationship as well as service content features into an unified preference learning process. Also provide aggregated services in only one application (social networking) which increases user’s interest towards the services. This system also provides security about subscribed services as well as documents/photos on online social network application. This system will utilizes services like Education, adventure, Home Services, Hotels & Travel, Restaurants and Shopping

A Critical review about Haratala (Orpiment)

Haratala (Arsenic trisulphide) is an inorganic compound with the formula As2S3. The Haratala is used without proper purification the toxic effects are Daha (burning sensation), Kampaka (tremors), Toda (pricking pain), Kshobha, Pida, Raktadusti (vitiates blood), Kushta (skin disease), Malinikaroti Gatram, Vata Kapha Prakopatamaka Roga, Mrtyusankakara. Coarse powdered material is less toxic because it can be eliminated in faeces before it dissolves, experimental evidence has shown a high degree of gastro-intestinal absorption of both trivalent and pentavalent forms of arsenic. Arsenic is eliminated by many routes (faeces, urine, sweat, hair, skin, lungs) although most is excreted in urine of man

ABSTRACT 1.INTRODUCTION Wireless mesh networks (WMNs) are being developed actively and deployed widely for a variety of applications, such as public safety, environment monitoring, and citywide wireless Internet services. The wireless backbone, consisting of wireless mesh routers equipped with one or more radio interfaces, highly affects the capacity of the mesh network. This has a significant impact on the overall performance of the system, thus generating extensive research in order to tackle the specific challenges of the WMN. This configuration adversely affects the capacity of the mesh due to interference from adjacent nodes in the network. Directional antennas and modified MAC protocols make the practical deployment of such solutions infeasible on a wide scale, the main issue in using multiple channels with a single radio is that dynamic channel switching requires tight time synchronization between the nodes. The protocol makes use of the knowledge of network topology by utilizing selective flooding of control messages in a portion of the network. In this way, broadcasting of control messages is avoided and thus the chances of network congestion and disruption of the flows in the network are reduced. A typical WMN application consists of three levels: wired networks, the WMN backbone, and mesh clients. Wired networks contain most resources in WMNs, such as file servers, file transfer protocol servers, etc. The WMN backbone is a collection of static wireless mesh routers. Traffic loads between the wired network and mobile users in mesh clients are transmitted by the WMN backbone in a multihop manner. Mesh clients can connect to the WMN backbone by establishing either wired or wireless links with mesh routers. WMN architecture as shown i

Chemoprevention of N-Methyl-N-Nitrosourea Induced Mammary Carcinogenesis with Raloxifene and Melatonin: Metabolic Changes in Female Rats

Abstract Chamilová M., P. Kubatka, K. Kalická, E. Adámeková, B. Bojková, I. Ahlers, E. Ahlersová: Chemoprevention of N-methyl-N-nitrosourea Induced Mammary Carcinogenesis with Raloxifene and Melatonin: Metabolic Changes in Female Rats. Acta Vet. Brno 2002, 71: 235-242. The aim of this work was to determine the selected parameters of carbohydrate and lipid metabolism in the mammary carcinogenesis induced with N-methyl-N-nitrosourea (NMU) in two doses, each by 50 mg/kg of body weight with a 7-day interval between them within the postnatal days 43 and 54 in female Sprague-Dawley rats. Chemoprevention started with the administration of melatonin (MEL, 4 µg/ml in water, from 15.00 h to 08.00 h) 12 days and raloxifene (RAL 5 mg/kg, 2 × weekly) 10 days before the application of NMU. Twenty-four weeks following the NMU administration the animals were killed, and the incidence, latency, frequency and volume of tumours were evaluated. The animals were divided into: tumour-bearing (TB) and non-tumourbearing (NTB) with the influence of RAL, MEL and their combination. While RAL and RAL plus MEL significantly decreased the incidence and frequency of tumours, the effect of isolated MEL was substantially lower. In the serum, an increase in the concentration of serum glucose in TB and also NTB animals was observed. In the liver of both the TB and NTB animals, the content of cholesterol (CH) and triacylglycerols (TG) decreased and the contents of phospholipids (PL) increased. RAL decreased the contents of CH and PL in the liver of NTB animals and increased the concentration of TG in both groups of animals. Administration of RAL to NTB animals decreased the concentrations of malondialdehyde (MDA) in the serum and thymus, in the bone marrow also in TB animals. MEL decreased the concentration of MDA in the bone marrow of TB animals. MEL increased the concentrations of serum glucose and glycogen content in the heart muscle of NTB animals. RAL plus MEL decreased the concentration of serum TG and PL and decreased the contents of CH and PL in the liver of TB as well as NTB animals. In the thymus and liver, combination of RAL+MEL decreased the MDA content compared with the RAL alone in NTB animals. The co-effect of two or more substances will be probably the optimal way in prevention of cancer. The co-effect of RAL and MEL shows to be a prospective way for influencing the mammary tumors. Breast cancer, female rats, raloxifene, melatonin, chemoprevention The hormonal therapy of the breast carcinoma is an inseparable part of the variety of therapeutic procedures. The substitution with estrogens has been considered for a long time as a dominant indication of therapy in postmenopausal women, and it has been recognized that approximately one third of women will have a benefit of this procedure. The use of estrogens protects these women against osteoporosis and decreases the cardiovascular risk, but on the other hand, increases the risk of breast and endometrium carcinom

Vascular and upper gastrointestinal effects of non-steroidal anti-inflammatory drugs: meta-analyses of individual participant data from randomised trials

Summary Background The vascular and gastrointestinal eff ects of non-steroidal anti-infl ammatory drugs (NSAIDs), including selective COX-2 inhibitors (coxibs) and traditional non-steroidal anti-infl ammatory drugs (tNSAIDs), are not well characterised, particularly in patients at increased risk of vascular disease. We aimed to provide such information through meta-analyses of randomised trials. Methods We undertook meta-analyses of 280 trials of NSAIDs versus placebo (124 513 participants, 68 342 personyears) and 474 trials of one NSAID versus another NSAID (229 296 participants, 165 456 person-years). The main outcomes were major vascular events (non-fatal myocardial in farction, non-fatal stroke, or vascular death); major coronary events (non-fatal myocardial infarction or coronary death); stroke; mortality; heart failure; and upper gastrointestinal complications (perforation, ob struction, or bleed). Findings Major vascular events were increased by about a third by a coxib (rate ratio [RR] 1·37, 95% CI 1·14-1·66; p=0·0009) or diclofenac (1·41, 1·12-1·78; p=0·0036), chiefl y due to an increase in major coronary events (coxibs 1·76, 1·31-2·37; p=0·0001; diclofenac 1·70, 1·19-2·41; p=0·0032). Ibuprofen also signifi cantly increased major coronary events (2·22, 1·10-4·48; p=0·0253), but not major vascular events (1·44, 0·89-2·33). Compared with placebo, of 1000 patients allocated to a coxib or diclofenac for a year, three more had major vascular events, one of which was fatal. Naproxen did not signifi cantly increase major vascular events (0·93, 0·69-1·27). Vascular death was increased signifi cantly by coxibs (1·58, 99% CI 1·00-2·49; p=0·0103) and diclofenac (1·65, 0·95-2·85, p=0·0187), nonsignifi cantly by ibuprofen (1·90, 0·56-6·41; p=0·17), but not by naproxen (1·08, 0·48-2·47, p=0·80). The proportional eff ects on major vascular events were independent of baseline characteristics, including vascular risk. Heart failure risk was roughly doubled by all NSAIDs. All NSAID regimens increased upper gastrointestinal complications (coxibs 1·81, 1·17-2·81, p=0·0070; diclofenac 1·89, 1·16-3·09, p=0·0106; ibuprofen 3·97, 2·22-7·10, p<0·0001; and naproxen 4·22, 2·71-6·56, p<0·0001). Interpretation The vascular risks of high-dose diclofenac, and possibly ibuprofen, are comparable to coxibs, whereas high-dose naproxen is associated with less vascular risk than other NSAIDs. Although NSAIDs increase vascular and gastrointestinal risks, the size of these risks can be predicted, which could help guide clinical decision making. Funding UK Medical Research Council and British Heart Foundation. Introduction Non-steroidal anti-infl ammatory drugs (NSAIDs) are among the most widely used drugs in the world. They are chiefl y used to treat pain, but their long-term use is limited by serious gastrointestinal side-eff ects. NSAIDs inhibit the two recognised forms of prostaglandin G/H synthase (also referred to as cyclo-oxygenase [COX]), namely COX-1 and COX-2. 1 Since the analgesic and antiinfl ammatory eff ects of NSAIDs are mediated by inhibition of COX-2, and their gastrointestinal side eff ects mostly by inhibition of COX-1, NSAIDs which selectively inhibit COX-2 might reduce the risk of gastrointestinal toxicity compared with other NSAIDs. Several such COX-2 selective drugs (collectively known as coxibs) were developed in the 1990s, and early trials comparing coxibs versus traditional NSAIDs (tNSAIDS) seemed to confi rm that coxibs at doses with similar analgesic effi cacy had less gastrointestinal toxicity. 2,3 Unfortunately, however, subsequent placebo-controlled trials also showed unequivocally that coxibs were associated with an increased risk of atherothrombotic vascular events. 4,5 Soon after these placebo-controlled trials were reported, a meta-analysis of randomised trials comparing a coxib versus placebo or a coxib versus tNSAID indicated that some tNSAIDs might also have adverse eff ects on atherothrombotic events, but that these hazards might depend on the degree and duration of suppression of platelet COX-1

All three systems have orbital obliquity measurements, WASP-24 and WASP-26 have been observed with Spitzer, and WASP-25 was previously comparatively neglected. Our light curves were obtained using the telescope-defocussing method and have scatters of 0.5–1.2 mmag relative to their best-fitting geometric models. We use these data to measure the physical properties and orbital ephemerides of the systems to high precision, finding that our improved measurements are in good agreement with previous studies. High-resolution Lucky Imaging observations of all three targets show no evidence for faint stars close enough to contaminate our photometry. We confirm the eclipsing nature of the star closest to WASP-24 and present the detection of a detached eclipsing binary within 4.25 arcmin of WASP-26.Publisher PDFPeer reviewe
