Recommendation Based On Comparative Analysis of Apriori and BW-Mine Algorithm

With The Growth of WWW recommending appropriate and relevant page to the user is a challenging task. In many web Applications, user would like to get recommendation based on their interest of surfing. Web Mining is used to extract relevant information for the user from logs, web content, hyperlinks etc. In this paper we will be using logs to recommend frequent access patterns to the users .This paper aims at using the logs of user ,cleaning logs , identifying users , identifying session , completing sessions from website structure and then using and comparing different recommendation algorithm like Apriori Algorithms and BW-Mine to recommend frequent items to the user. We will also be comparing different recommendations Algorithm with the help of example. The fundamental of finding access patterns with Apriori is that any set that occurs frequently must have its frequent subset. The fundamental of finding access pattern with BW-Mine, it constructs the WB-table, VI-List, and HI-Counter for finding frequent patterns

An Approach to Recommend Pages to User after Path Completion

With the huge amount of data available on the web, the effective and timely search is most important aspects. Because of tremendous USAge of web the size of the log files are becoming huge day by day. Web Mining which is an application of data mining can be used to improve web performance by generating patterns in the log files. Web Pre-fetching based on recommendation can be used to improve web performance. This paper proposes an architecture that recommends pages to the user based on studying the browsing activity of the user and other user of same USAge profile and completing it in every aspects and then recommending the pages which can be pre-fetched to improve web performance. This paper proposes about the path completion which shows users interest and then recommending pages to the user which will result in effective recommendation

This experiment was conducted to study the effects of addition of purified tannins at low concentration into hay diet on in vitro gas emission and rumen fermentation. Treatments consisted of: P0 (control hay), P1 (hay + 0.5 mg chestnut tannin/ml of incubation medium), P2 (hay + 0.5 mg/ml mimosa tannin), P3 (hay + 0.5 mg/ml quebracho tannin) and P4 (hay + 0.5 mg/ml sumach tannin). Variables measured were gas production kinetics, organic matter digestibility (OMD), methane production, expressed as percent methane in total gas and methane production per unit organic matter digested, and volatile fatty acid (VFA) production. The results showed that in most cases tannin addition at 0.5 mg/ml decreased significantly (P < 0.05) total and rate of gas production, OMD, total VFA and iso-VFA. Tannin addition also decreased methane production (P < 0.05). Hydrolysable tannins seemed to have better methane reduction effect than condensed tannins. The best tannin to decrease methane was chestnut tannin, which contained hydrolysable tannins. Present research should be shifted from evaluating only the effect of condensed tannins in reducing methane emission towards some potential hydrolysable tannins since the nature and the toxicity of hydrolysable tannins are quite diverse

Transition Metal Doping in CdS Quantum Dots: Diffusion, Magnetism, and Ultrafast Charge Carrier Dynamics

Transition metal (TM) doping in pristine II-VI semiconductor quantum dots (QDs) is known to add several otherwise unavailable properties by introducing midgap states in the host material. Albeit being extensively investigated, the periodicity of the observed properties with respect to the electronic structure has not been attempted so far. In this work, we investigate CdS QDs doped with several different TM ions (Mn, Fe, Co, Ni, and Cu) using extended X-ray absorption fine structure spectroscopy to study dopant-induced structural perturbations and femtosecond transient absorption (TA) spectroscopy to study the ultrafast charge carrier dynamics. This provides solid evidence for the origin of magnetization in doped QDs that has been lacking despite extensive studies. Further, we demonstrate that the ionic radius and the dopant oxidation state play crucial roles in determining the dopant-anion bond lengths. Based on the investigation of the relaxation pathways of excited charge carriers using ultrafast TA spectroscopy, we hypothesize that there exists photoinduced switching between multiple oxidation states in some dopants

Perceived stress among gravid and its effect on their oral health in Sri Ganganagar, Rajasthan, India

Background: The gestation period presents unique stresses that challenges overall psychological adaptation of a women. The present study is designed especially to focus on evaluating the effect of perceived stress on pregnant women and its effect on their oral health.Methods: A cross-sectional study was conducted among 18-30 years old, pregnant women in the Sri Ganganagar city. Prior to the clinical examination a questionnaire was used in order to collect the information which comprised of three parts and were completed through an interview. The first part comprised of demographics questionnaire, second part included oral hygiene questionnaire and third part was perceived Stress Scale. Descriptive analysis described demographics and socioeconomic characteristics. Multivariate analysis was used to describe the association between stress and various characteristics. Chi-square and Kruskal-wallis test was used to study the association of independent variables with level of stress.Results: The high stress was reported among those females who were aged > 25 years (46.66%), living in rural areas (73.33%), were employed (57.77%), were in third trimester of pregnancy (96.66%) and had no previous pregnancy experience (67.77%). The mothers in high stress group had high levels of dental diseases when compared to the other two groups (low and moderate stress).Conclusions: Based on the results, this study emphasizes on the need for a continued effort to improve the mental and oral health status of gravid women so as to reduce the incidences of psychological and physical troubles in this population predicted

Traditional wisdom confirmed by scientific research: Jatropha species from Mexico is non-toxic

The seeds of _Jatropha platyphylla_, available on the pacific coast from Sinaloa to Michoac&#xe1;n including the Nayarit and Jalisco states in Mexico, are consumed by local communities after roasting them in a manner similar to that used for peanuts. The kernels and kernel meal of _J. platyphylla_ were found to be free of phorbol esters but the kernel meal contained antinutritional factors: trypsin inhibitor, lectins and phytate at levels similar to those in _J. curcas_ kernel meal. However, trypsin inhibitor and lectins are heat labile so this explains why the local people can eat roasted seeds without ill effect. The fatty acid profile of _J. platyphylla_ oil was similar to that of _J. curcas_ and the kernels of both these species contained _ca_ 58% oil. The crude protein content of _J. platyphylla_ kernel meal was 75% against 60% in _J. curcas_, and the amino acid compositions were similar. All the essential amino acids, except lysine, were more abundant than, or comparable to those, in soybean meal or the FAO Reference protein.&#xd;&#xa;&#xd;&#xa;&#x9;Tilapia and other fish species have been found to be particularly sensitive to Jatropha toxins. For this reason they are useful subjects for bioassays. The heated _J. platyphylla_ kernel meal was included in a standard diet (crude protein 36%) for Nile tilapia (_Oreochromis niloticus_) to replace 50% of the fish meal protein. The fish grew as well as those on a control diet in which none of the fish meal was replaced and those on a diet in which 50% of the fish meal protein was replaced by soybean meal. In all the three groups, blood biochemical parameters that serve as biomarkers for toxicity were within the normal ranges. This study confirmed the non-toxic nature of _J. platyphylla_. &#xd;&#xa;&#xd;&#xa;&#x9;The kernels and kernel meal of this species could help alleviate protein and energy deficiency in malnourished children in the lower mountain skirts of pacific coastal areas of Mexico. It could also be used to produce new cultivars with desirable traits using conventional inter species cross breeding and molecular breeding techniques. &#xd;&#xa
