Retaining walls are an integral part of almost all infrastructure projects, to support vertical or near vertical backfills. As the sectional dimensions of retaining wall are function of lateral earth pressure on wall, so reducing the lateral earth pressure on wall with also reduce the sectional dimension of the wall and will leads to overall economy to the structure. Construction of relief shelves at various elevations.into the backfill use of tire chips as light weight backfill provision of compressible inclusion are some of the techniques used by several researchers to achieve the reduction of earth pressure on retaining wall.A similar study has also investigated the possible reasons behind the failure of a cantilever retaining wall with relief shelves, which is located in the heart of Hawassa city, Ethiopia and also laid suitable relief shelf parameters by using computational tool. To study the influence of relief shelf on lateral earth pressure distribution on wall, 1-g small scale,physical model tests are carried out in a stainless steel tank having dimensions of 1.2m length, 0.31m width and 0.7m depth. Present study examines the effectiveness of relief shelves on lateral earth pressure reduction, which has concluded that provision of relief shelves on non-yielding rigid retaining wall provides significant amount of reduction in total thrust on wall by means of small scale physical model tests and numerical analysis. For retaining wall of 8m height having surcharge of 50kPa placed at 0.5m away from wall face, provision of 3 relief shelves having width ranging from 0.4-1.8m can reduce total thrust in range of 4-27.5%.

 Abstract

Uncertainty in the price of the fossil fuels and also rapid depletion of them gives rise to the alternate energy sources. From many decades people uses the solar energy as a main source of energy especially in the drying of food items. Solar dryer is the device that can be used for drying of food items which is sustainable by small communities, gives hygenic and quality products. Mainly an indirect solar dryer and mixed mode solar dryer performance and design were studied from the literatures. The tunnel type dryer has the advantages of the direct sun light by ultra-violate stabilized cover and absorber plate is provided at the base. The no load performance index is the new terminology for checking the performance of the different dryer in the forced and natural convection mode. The drying of fish near to the coastal line of India is the major business for fisherman hence the drying done by open sun drying method in very unhygienic condition. By implementing solar dryer over that regions quality of dried fish will increase and the drying time will be decrease. The no load performance index (NLPI) of the mixed mode solar dryer was 0.633 which was highest among the rest of the dryer under the natural convection mode. The new mixed mode type solar dryer can be developed in which the absorber plate is attached with the tunnel type dryer.

 Abstract

The history of Indian freedom struggle would be incomplete without mentioning the contribution of women. The sacrifice made by the women of India newline will occupy the foremost place. The history of freedom struggle is replete with the saga of sacrifice, selflessness, bravery of women. Many of us don�t know that there were hundreds of women who fought side by side with their male counterparts. They fought with true spirit and undismayed courage. The Indian women broke away from various restrictions and got out of their traditional home-oriented roles and responsibilities. So, the participation of women in the freedom struggle and National awakening is simply incredible and praiseworthy. However, it is not easy for women to fight as warrior�s in the male dominating society. Even though females tried to change the perception of such orthodox people who thought women are meant to do only household chores. Moreover, females not only sacrifice their lives but also combat such issues. Rani Laxmi Bhai was one of such women who fought against British role by mitigating all odds, hence this paper entitles to highlight the legacy that women showed in the history by showing their fierce nature.

Abstract: Forest plant protection is a chronic problem for sustainable development of our country. Hence forest ecosystem is one of the main natural bio-resources that we have to conserve. But still there are many threats causing damages to our forest greenery. The major existing threat is the damages caused by insect pests. They are the most destructive agents affecting forest and shade trees. Rhinolophus beddomei (Lesser woolly horseshoe bat), a forest dwelling species, being a major insect eater, play a key role in the biological control of insect pests. Being the only flying mammal, bats are capable of sustained flight and are the most gregarious and successful group of beneficial animals to the ecosystem and have lured the attention of ethologists. The present study has analysed the study species availability and its activity as �Pest Managers�. Few sample areas from forest ecosystem of Kalakad Mundanthurai Tiger Reserve (KMTR) was taken as study site which is known for its forest ecosystem with caves, water bodies, streams and forest tree cover. Dietary habitat analysis of study species was done by faecal pellet analysis. The results explain and justify R. beddomei, play a potential role in green management and there by helps to conserve biodiversity in forest ecosystem.

 Abstract

Thermophiles can be found in almost any ecological niche from fresh and salt water to terrestrial and extreme environments, including metal-contaminated habitats. Most of the strains are able to produce extracellular polymeric substances (EPS) mainly of polysaccharidic nature which serve as biosorbing agents by accumulating nutrients from the surrounding environment and also play a crucial role in biosorption of heavy metals. Structural and compositional characterization of new spp. of Streptococcus thermophilus isolated from hot water spring under stressed and normal conditions were analysed. The structural spectroscopic information was considered together with inductively coupled plasma-mass spectrometric (ICP-MS) analytical data on the content of the heavy metal cations (Co2+, Cu2+, Cr2+, Fe2+ Zn2+) in the bacterial cells. As bacteria was able to uptake all the five heavy metals from the culture media in significant amount, the metabolic changes in the bacterium was considerably differentiated by IR spectra. Spectra revealed that chemical compounds of various functional groups were involved during accumulation of these heavy metals.

 Abstract

Members of the family Coronaviridae cause a broad spectrum of animal and human diseases. Until 2003, coronaviruses attracted little interest beyond causing mild upper respiratory tract infections. This changed dramatically in 2003 with the zoonotic SARS-CoV (Severe Acute Respiratory Syndrome Coronavirus) and the more recent emergence of MERS-CoV (Middle East respiratory syndrome Coronavirus) has confirmed the coronaviruses as significant causes of severe respiratory disease. SARS-CoV is thought to be an animal virus from an as-yet-uncertain animal reservoir, perhaps bats, that spread to other animals (civet cats) and first infected humans in the Guangdong province of southern China in 2002(WHO 2020) and spread to five continents through air travel routes, infecting 8,098 people and causing 774 deaths. Since 2012, MERS-CoV has been emerged in the Arabian Peninsula and was exported to 27 countries including Algeria, Austria, Bahrain, China, Egypt, France, Germany, Greece, Islamic Republic of Iran, Italy, Jordan, Kuwait, Lebanon, Malaysia, the Netherlands, Oman, Philippines, Qatar, Republic of Korea, Kingdom of Saudi Arabia, Thailand, Tunisia, Turkey, United Arab Emirates, United Kingdom, United States, and Yemen (WHO 2019). Total of ~2,494 individuals and claiming 858 lives were reported due to the infection of MERS-CoV. SARS-CoV-2 is associated with an on-going outbreak of atypical pneumonia (Covid-2019) that has affected over 209 countries and territories around the world and two international conveyances the Diamond Princess Cruise ship harboured in Yokohama, Japan, and the Holland America's MS Zaandam cruise ship. Up to 14, 46, 981 people affected of which 1, 055,207 active cases and 83,090 deaths are declared 08 April 2020. On January 30th 2020, the World Health Organization declared the SARS-CoV-2 epidemic as a public health emergency of international concern.

 Abstract

Leptospirosis, a zoonosis with a worldwide distribution is an acute febrile illness caused by spirochetes of the pathogenic Leptospira interrogans. The antileptospioral screening of the synthesized 1, 4 �dihydropyridine derivatives against Leptospiral grippotyphosa organism were carried out. Motility of the spirochetes were examined by micro dilution method under 20X dark field microscopy with two hours interval. The reduction in the motility of the organisms and the arrest of the growth of the organism indicates the leptospiral activity of the compounds. Among the synthesized compounds (CR1 - CR5) compound CR5 showed decrease in the motility at higher concentration, where as compound CR2 was found to inhibit the motility at higher concentration after 4 hrs.
