Effective surveillance and monitoring of Aedes albopictus is essential for the possible prediction and implementation of the preventive measures. We tested BG sentinel mosquitito traps with BG lure to collect adults as an alternative surveillance tool in relation to larval indices. Study was carried out in Calicut District, Kerala, India. Three villages in the district were selected by random sampling as study area. In each village, 50 houses were selected as study site for trap collection, larval survey and fever surveillance. Study was conducted for six months from July to December, 2017. Number of adults of Ae.albopictus collected in BG sentinel traps was only 84 in 22 collections spanning over six months (mean 3.82, 95% CI-2.57-5.06).Though the larval indices were high; no epidemic was reported from the study area. There was no correlation between adults collected and larval indices. Adult collection showed a positive correlation with most of meteorological parameters. Larval indices showed no correlation with climatic factors.BG mosquitito trap was found to be not successful for adult surveillance in the area. More studies are required using different traps to suggest adult traps as an alternative to currently used larval indices. Larval indices were high but no cases reported. Our study shows that a more reliable monitoring mechanism is required for Ae.albopictus to enable prevention, to introduce abatement and its evaluation.

The use of nondestructive testing (NDT) techniques to estimate concrete in-place strength has been broadly studied, with proof of their usefulness in complementing destructive testing (DT). However, the use of DT techniques still dominates. The main objective of this investigation was to compare the performance of three NDT techniques—the rebound hammer, Nitto hammer, and pullout tests—to determine in-place strength. NDT-versus-strength correlation curves were fit to data measured from thick concrete slabs. Strength was measured from cast-in-place cylinders. Analyses of NDT sensitivity, uncertainty, and variability are presented. A new parameter to quantify the performance of the NDT techniques is proposed. This parameter is the limit error between the measured and estimated strengths, which combine uncertainty and variability analyses. The analysis shows that the least limit error for predicting in-place strength was achieved by the rebound hammer test when one testing location was considered or by the pullout test for two or more testing locations.

Linguatulosis is a zoonotic disease caused by Linguatula serrata. Ruminants are the most important intermediate hosts of this parasite. This study was carried out to evaluate the prevalence rate of Linguatula serrata infection in slaughtered sheep in slaughterhouses of Tehran province, Iran. A total of 767 slaughtered sheep were selected in 2016 using systematic random sampling and their mesenteric lymph nodes were examined for Linguatula serrata nymph detection. Then, the infection rate and its intensity in different ages, sex and seasons were assessed. It was revealed that 66 sheep (8.6%) were infected with Linguatula serrata nymphs. Intensity of the infection was 4.88 nymphs. The highest rate of infection was observed in sheep aged over 19 months (P≤0.05). The highest infection rate and intensity of the infection were recorded in winter and summer, respectively (P≤0.05). Besides, intensity of the infection in females was significantly higher than that in males (P≤0.05). This study indicates the importance of Linguatula serrata infection in sheep in Tehran province, and the need to improve preventive measures for reducing the rate of infection and preventing transmission of the infection from sheep and other ruminant to other animals and humans in Iran.

Aggressive behaviors by adolescents in Indonesia has perceived as national problem. This problem ofbehavior occur among all background of teenagers, including young people who had religiousbackground. There are two purposes of the study: 1). To examine the difference of aggressivenessbetween adolescent living in pesantren and adolescent living outside pesantren; and 2). To examine thedifference of aggressiveness among adolescents doing different frequency of religious fasting (shiyam),especially non-obligatory (sunnah) fasting on Monday or Thursday. The population of study was 11 to 21years old male-Moslem adolescent living in Kelurahan Bangunharjo, Semarang. Samples of study takenwith random sampling, based on data of residences in Kelurahan Bagunharjo Semarang. Twohypotheses were proposed in this study: 1). There are different aggressiveness between adolescentsliving in pesantren and ones living outside of pesantren; and 2). There are different aggressivenessamong adolescents doing different frequencies of Monday-Thursday shiyam. The first examinationemploying independent sample t-test resulted in t=-4,902 which p=0,00 (p<0,01), showed that the firsthypothesis was proved: there was a very significant difference of aggressiveness between the group ofMuslim-male adolescents living in pesantren and the group of others, the first group showed loweraggressiveness. The second examination employing one-way anova resulted in F=16,736 which p=0, 00(p<0, 01), showed that the second hypothesis was also proved: there was a very significant difference ofaggressiveness among the groups of Muslim-male adolescents with different frequency of religiousfasting (shiyam): the more frequency of religious fasting, the lower aggressiveness was. The result ofstudy suggested that both religious living environment and religious fasting might give contribution todecrease aggressiveness on adolescents.

AbstractAedes albopictus (Skuse) is a widespread invasive mosquito vector species with a distribution including tropical and temperate climates; its range is still expanding. Aedes albopictus populations were recently detected in Morocco and Algeria, the countries neighboring Tunisia, but never in Tunisia. In 2018, we initiated an intensive field study using BG-Sentinel Traps, ovitraps, larval surveys, and citizens’ reports to determine whether Ae. albopictus populations exist in Tunisia. In October 2018, we collected adults and larval stages of Ae. albopictus in Carthage, Amilcar, and La Marsa, less than 20 km, northeast of Tunis, the Tunisian capital. These Ae. albopictus larvae were primarily collected from Phoenician funeral urns at the archeological site of Carthage. This is, to our knowledge, the first detection of Ae. albopictus in Tunisia.
