In this paper, we introduce the notion of anti Q- fuzzification of right Rsubgroups in a near-ring and investigate some related properties. Characterization of anti Q- fuzzy right R-subgroups and onto homomorphic image of anti Q- fuzzy right R- subgroup with the inf property with respect to a s-norm are given.

The ability of the laboratory-reared egg parasitoid, Trichogramma chilonis Ishii to disperse and locate sentinel egg cards in sugarcane field was evaluated. The dispersal behaviour was monitored at different crop ages of 45 days, 3 months, 5 months, 7 months and 9 months through egg-parasitism in sentinel cards with Corcyra cephalonica (Stainton) eggs in 24 h time. The sentinel cards were placed at distances of 1, 3, 5, 7, 10, 12, 15, 20, 25 and 30 m in eight cardinal directions from the release point of the parasitoid. The effects of distance from the release point, wind direction and crop age on the host location were evaluated. Distance had a clear proportional impact on the dispersal probability but this association was complicated by the fact that distance effects changed with crop age. The dispersal of the parasitoid was found to be the highest in 45 days old crop and the lowest in 7 months old crop. The parasitoid was found to move up to 10m effectively up to 5 months of crop age which declined thereafter. Although dispersal was found up to 30m, more uniform parasitism was observed in 10m circle surrounding the release point. The direction of wind was not associated with the rate of dispersal. The influence of distance, direction and age of the crop on adult emergence was not found to vary distinctly. The inference of differential ability of the parasitoid to move in the sugarcane field in securing uniform dispersal and in fixing adequate number of release points for inundative releases are discussed.Keywords

The Western Ghats of India is among the top 25 biodiversity hotspots in the world. About 43% of the reported 117 bat species in India are found in this region, but few quantitative studies of bat echolocation calls and diversity have been carried out here thus far. A quantitative study of bat diversity was therefore conducted using standard techniques, including mist-netting, acoustical and roost surveys in the wet evergreen forests of Kudremukh National Park in the Western Ghats of Karnataka. A total of 106 bats were caught over 108 sampling nights, representing 17 species, 3 belonging to Megachiroptera and 14 to Microchiroptera. Acoustical and roost surveys added three more species, two from Microchiroptera and one from Megachiroptera. Of these 20 species, 4 belonged to the family Pteropodidae, 10 to Vespertilionidae, 3 to Rhinolophidae, 2 to Megadermatidae and 1 to Hipposideridae. We recorded the echolocation calls of 13 of the 16 microchiropteran species, of which the calls of 4 species (Pipistrellus coromandra, Pipistrellus affinis, Pipistrellus ceylonicus and Harpiocephalus harpia) have been recorded for the first time. Discriminant function analyses of the calls of 11 species provided 91.7% correct classification of individuals to their respective species, indicating that the echolocation calls could be used successfully for non-invasive acoustic surveys and monitoring of bat species in the future.Keywords

Modified 9Cr-lMo (P91) steel is used in fossil-fuel fired power plants due to its good thermo-physical, weldability, fabricability and high temperature mechanical properties. Toughness of the P91 weld metal, deposited by the shielded metal arc welding (SMAW) process, is reported to be lower than that deposited by the gas tungsten arc welding (GTAW) process. In spite of this, considering the higher deposition rate and economics, the SMAW process is very popular in industry. Thus, achieving adequate toughness in the P91 weld metal deposited using the SMAW process is an important requirement to qualify the weld joints.
Weld joints were prepared using the SMAW process and subjected to post-weld heat treatment (PWHT) at 760°C for durations of 3, 10 and 100 hours. Microstructural observations revealed coarsening of the lath martensite and the precipitates accompanied by an increase in toughness with increase in PWHT duration from 3 to 10 hours. The effect of PWHT duration on subzero toughness was found to be significant, with the subzero toughness increasing with increase in PWHT duration upto 10 hours and then decreasing on PWHT for 100 hours. Increase in sub-zero toughness could be attributed to adequate tempering, while the decrease in toughness on PWHT for 100 hours was attributable to the formation of fresh martensite during cooling from the PWHTtemperature. This variation of toughness of the SMA weld metal with duration of PWHT needs better understanding from the view point of the composition of the weld metal. Detailed microstructural analysis was carried out to understand the reasons for the variations in the mechanical properties. This paper presents and discusses the results of this experimental investigation.

Background: Malignant hyperthermia (MH) is a potentially fatal pharmacogenetic disorder of the skeletal muscles that presents as a hypermetabolic response to potent inhalational anaesthetic agents such as halothane, sevoflurane, desflurane, isoflurane and the depolarizing muscle relaxants like succinylcholine, and rarely, due to vigorous exercise and heat.
Method: A systematic review was carried out using the database PubMed central and MEDLINE using the keywords General anaesthesia, malignant hyperthermia, systematic review. This literature search yielded 1174 articles published up to the year 2018. INCLUSION CRITERIA: peer reviewed retrospective and prospective cohort studies, cross sectional studies, case descriptions were included in the study.
Objective: The objective of this systematic review is to provide a wide and objective assessment of the incidence of Malignant Hyperthermia in patients undergoing surgery with or without general anaesthesia

The aim of this systematic study is to know whether the third molar is to be removed or not when in line of fracture. The angle fracture of mandible is one of the most common site because of the presence of thin cortical bone and the presence of third molar. The presence of third molar increases the incidence for the angle fracture and decreases the risk for condyle fracture. The search terms were the “third molar AND angle fracture” were used to search in the pubmed. Of the total 128 article, 22 relevant article was reviewed. The search criteria was for the last 5 publication year 2013-2018 the resultant articles were 50. In which the duplicates and irrelevant article were removed (28 articles).Keywords

Web mining is one among the thrust area of research in the data mining domain. The classification of query recommendation can be divided into two major classes that are document-based approach and log-based approach. Log-based method can get relatively good query recommendation and find query inner relation. Query flow graph is one of log-based method and get relatively good recommendation. However, query flow graph cannot get query semantic information. And there are many isolated nodes because of data sparseness. Therefore, word2vec is used to define the query semantic and add query semantic to query flow graph. That can be able to modify query transfer probability which is calculated by query flow graph. At the same time, we can get connection between the isolated queries that are related but no connection due to the data sparseness and the inaccuracy of session split. Empirical tests are conducted in accordance with the AOL log. From the results the efficiency of the approach in suggesting queries and F1 value is about 20% higher than the traditional query flow graph.Keywords
