Background: Dengue virus can cause a wide range of illness in humans, from unapparent infection, to classic dengue fever and to fatal dengue haemorrhagic fever. Until a vaccine becomes available for public health use, primary prevention of transmission is crucial to decrease the burden of dengue, and control of Aedes is the only available strategy.Methods: The mosquito larval survey was carried out in the month of November 2017 in Echangadu, a coastal village in Puducherry to assess mosquito breeding sources for the presence of dengue vector species. The survey was performed by selecting houses where freshwater was available. For each household, the presence or absence of possible breeding sources were recorded, as well as the presence or absence of mosquito larvae.Results: Of the 102 houses surveyed, 20 of the houses were infested with Aedes larvae. A total of 182 containers were found in these households of which 47 containers were positive for Aedes larvae. Coconut shells, plastic, metal and discarded containers were the most often found breeding sites.Conclusions: The larval surveillance indicators among the households surveyed revealed a very high risk of future dengue outbreak in the village. All the containers examined including those positive for Aedes larvae were safely disposed.

Technologies for Striga control have not been widely adopted because of the mismatch between technologies and farmers' socio-economic conditions. This study used a participatory rural appraisal technique at the village, household and plot levels to diagnose the extent of the Striga problem in two agro-ecological zones in southern Mali. This has resulted in an understanding of farmers' attitudes and constraints to Striga control, and opportunities for the development of sustainable technologies suitable for a wide range of farming conditions. Results show that the degree of Striga infestation, levels of farmer knowledge and control practices vary substantially across village territories and fields, and that the severity of the infestation is clearly linked with soil fertility condition and farming practices. It was concluded that in general, the Striga control interventions that would most likely appeal to farmers would be those that will simultaneously improve soil fertility and suppress the development of Striga.

In carrying out marriage there are harmony and conditions that must be met, includes the existence of a prospective husband, prospective wife, marriage guardian, two witnesses, and qobul consent, the provision is based on KHI article 14 in chapter IV concerning the terms of marriage. But in 2019, the East Java region imposed a urine test on the bride and groom as additional marriage conditional. Urine test conducted for the bride and groom is a policy of the regional office of the ministry of religion in East Java in an effort to reduce the number of drug abuse. Because the number of drug users in East Java is very high and has expanded to remote areas of the village so that prevention and control effort are needed evenly, efficiently and structured. With the enactment of the policy of the regional office of the ministry of religion in East Java above, the religious affairs office obliges the bride and groom to take a medical and urine test. Implementation of this urine test will not obstruct the marriage process of the bride and groom, if one or both brides are proven to use narcotics, the bride and groom will get rehabilitation treatment by the East Java BNNP. This is done so that the condition in question does not become worse after marriage. Using the analysis of Istihsan al Syarakhsy shows that there is harmony and as a reinforcement that the urgency of urine tests for brides is a form of response both done in an effort to get justice and benefit.

Outbreaks of dengue disease have been reported from many parts of India including northeastern States. There were reports of dengue disease outbreaks from Moreh town in Manipur during 2007-2008 and from Pasighat in Arunachal Pradesh during 2012 from northeast India. The first outbreak of dengue-like fever in Mizoram was reported on 30th August from Tuikual North ‘C’ Mual, Aizawl, followed by consecutive outbreaks at 10 localities between August and December 2016 within Aizawl city. In these localities, epidemiological and entomological studies were conducted to identify the disease and its vector. Blood serums were collected from the patients for the serological confirmation and Aedes mosquitoes (adults and larvae) were collected for vector identification and confirmation. There were 580 (NS1=384, IgM=196) patients confirmed with the disease from 11 localities in Aizawl and Ae. aegypti were identified as a potential vector species. There was no predilection towards sexes and all age group are affected with a median age 30. Parameters of entomological study revealed high density of vector mosquito in the study areas. Public health actions pertaining to the prevention and control of the disease were implemented. As dengue is included among the notifiable diseases in India, government authorities should strengthen manpower, case management and laboratory support, and regularly organizing interactive co-ordination meetings at all levels to sensitize public through IEC and awareness programmes as well as source reduction of Aedes mosquito breeding.

In recent years an increasing emphasis has been placed on the study of high temperature intermetallic compounds for possible aerospace applications. One group of interest is the B2 aiuminides. This group of intermetaliics has a very high melting temperature, good high temperature, and excellent specific strength. These qualities make it a candidate for applications such as turbine engines. The B2 aiuminides exist over a wide range of compositions and also have a large solubility for third element substitutional additions, which may allow alloying additions to overcome their major drawback, their brittle nature.One B2 aluminide currently being studied is cobalt aluminide. Optical microscopy of CoAl alloys produced at the University of Missouri-Rolla showed a dramatic decrease in the grain size which affects the yield strength and flow stress of long range ordered alloys, and a change in the grain shape with the addition of 0.5 % boron.

In domestic scientific and public opinion, interest in religion as a new worldview paradigm is very high. Today's attention to the Christian religion in our society is connected, in our opinion, with the specificity of its value system, which distinguishes it from other forms of consciousness: the idea of ​​God, the absolute, the eternity of moral norms. That is why its historical forms do not receive accurate characteristics and do not matter in the mass consciousness. Modern religious beliefs do not always arise as a result of the direct influence of church preaching. The emerging religious values ​​are absorbed in a wide range of philosophical, artistic, ethical ideas, acting as a compensation for what is generally defined as spirituality. At the same time, the appeal to Christian values ​​became very popular.

This study was conducted with the aim of evaluating the role of information and information resources in the awareness, control, and prevention of COVID-19. This study was a descriptive-analytical survey in which 450 participants were selected for the study. The data collection instrument was a researcher-made questionnaire. Descriptive and inferential statistics were used to analyze the data through SPSS. The findings show that a wide range of mass media has become well known as information resources for COVID-19. Other findings indicate a significant statistical difference in the rate of using information resources during COVID-19 based on age and gender; however, this difference is not significant regarding the reliability of information resources with regard to age and gender. Health information has an undisputable role in the prevention and control of pandemic diseases such as COVID-19. Providing accurate, reliable, and evidence-based information in a timely manner for the use of resources and information channels related to COVID-19 can be a fast and low-cost strategic approach in confronting this disease.
