 Abstract

The main aim of this study is to investigate how artificial intelligence is used to estimate pile capacity and load-settlement behavior of piles implanted in sand and mixed soils. Pile foundation analysis and design in unsaturated soils require consideration of the mechanical characteristics of the soil and the soil-pile interface. Artificial neural networks have been extensively employed in the last two decades to construct effective empirical models for various geotechnical issues [1]. Pile foundations are often utilized when the higher soil layers are weak and unable to sustain the super-structural loads. For the super-structural loads, piles are used. Consequently, a structure's stability and safety rely heavily on its piles' performance. Pile behavior is accurately predicted to guarantee that the structure and serviceability meet expectations. Once the field equipment is in situ, the behavior of the affected ground's Settlement and its subsurface environment are periodically observed. The surface settlement markers were installed, allowing us to see what was happening underneath and what was happening on top during Vibro-compaction. When the magnets are placed at various heights on the spider magnet extensometers, it is easy to see which soil strata are caused during load settlement.

 Abstract

Sport is a universal activity. It makes no distinction based on race, caste, or gender. Sports participation benefits not just one's health but also one's complete development. The participation of women in sport has been a problem that has been mostly ignored by most countries, which explains why female sport participation has been low in recent years. In the past, men were allowed to engage in the majority of sports and games, whereas women were not. They are subjected to a variety of limitations, including physical, mental, social, and religious. Later on, they began to participate actively in all sporting events. Sport for women is currently a rapidly expanding factor in every emerging country. This subject has been studied by researchers at various times. Scenarios from the Rig-Vedic Period, the Post-Vedic Period (Upanishads, Puranic, and Smriti Periods), the Medieval Period, the British Period, and the Post-Independence Period. This study was conducted using a descriptive method. Data came from a variety of sources, including research publications, journals, periodicals, research papers that were published in reputable journals, the internet, and a lot of different conversations. Despite physical, physiological, psychological, social, religious, and economic barriers, Indian women have done well in a number of sports and games. If you've ever heard of the "Queen of Indian Track and Field" or "The Payyoli Express," you'll know what I'm talking about. Usha Pilavullakandi Thekkeparambil is a well-known and successful Indian female athlete. She received the aforementioned awards for her outstanding performance on the track and field. She was born on June 27, 1964, in Payyoli, a hamlet in Kerala's Kozhikode district. She struggled with health issues as a child, yet she showed signs of being a superb athlete as early as primary school.

 Abstract

The uses of insecticide for mosquito control are increasingly becoming limited. The control measure were largely based on the use of chemical pesticides which develop resistance in the target population The problems in continued long term use of toxic insecticide include pest resistance and negative impact on natural enemies, which suggest a clear need for alternatives. Biolarvicides are biological products that are added to water to kill mosquitoes at the larval stage. Biological control is the most effective way to fight against larva as it prevents the birth of new mosquitoes and does not pollute the environment or pose health risks. Aedes aegypti, is responsible for dengue fever and yellow fever, in India where the number of these fever cases has increased significantly in recent years. Seaweeds have shown a wide range of bioactive properties. In this connection, the present study was an attempt to find out the larvicidal activity of different solvent extracts of two seaweeds Ulva fasciata and Grateloupia lithophila against the dengue and yellow fever causing mosquito, Aedes aegypti.

 Abstract

Odontella aurita is a promising nutracuetical being rich in omega fatty acids and fucoxanthin. A strain of O. aurita was isolated from the waters of Bay of Bengal and a pure culture was established. The identification of the isolate was confirmed through scanning electron microscopy. The pigment profile of O. aurita was analyzed through HPLC. The isolate was found to be very rich in fucoxanthin and had moderate levels of ? carotene. The culture medium was optimized. Urea and ammonium chloride were found as the most suitable sources of nitrogen for culture. Supplementation of the nutrient medium with Nualgi, a commercial formulation of micronutrients on a silica base was found to promote growth.

 Abstract

In the present investigation, variability induced by gamma rays and Ethyl methane sulphonate (EMS) for different quantitative traits viz., plant height, days to 50% flowering, cluster/ plant, pods/plant, seeds / pod, 100-seed weight (g) and yield/plant (g) was studied in M3 generation of green gram (Vigna radiata L. Wilczek). A significant shift in mean values in the positive direction was observed for all the quantitative traits studied. Estimate of genetic parameters (genotypic coefficient of variation, heritability and genetic advance) for the yield and its components were higher than the control in M3 generation. The increased genetic variance in the treated material is a reliable indication of the effects of mutagens.

 Abstract

Staphylococcus aureus is one of the most common and important pathogen, responsible for the majority of nosocomial infections. Nasal carriage is a major risk factor for S.aureus infection that differs from person to person. 200 nasal swabs (100 from hospitalized patients and 100 from healthy individuals) have been collected as per standard policy protocols. Detailed history was collected and only those personnel were included in the study who had not taken any antibiotic 7 days before sample collection. S.aureus isolates were confirmed by various biochemical tests as per latest CLSI guidelines. Cefoxitin Disk Diffusion test was performed for the detection of methicillin resistance and antibiotic susceptibility was performed against different antibiotics as per CLSI guidelines. Out of the 100 healthy subjects 49% S.aureus and 8.16% MRSA isolates were obtained while as out of 100 hospitalized subjects 71% S.aureus and 39.4% MRSA isolates have been detected from the nasal swabs. Penicillin was found to be the most resistant drug in both groups of isolates where as Vancomycin and Linezolid have been the drugs of choice. A significant difference was analyzed when the resistant rate of HA-MRSA against HA-MSSA was compared (p<0.0001). Significant difference was noticed while comparing resistant patterns of CA-MRSA against CA-MSSA (p<0.0001). A significant difference was verified when we compared the resistant rate HA-MRSA against CA-MRSA (p<0.0001). Prevalence of nasal carriage MRSA was higher in hospitalized patients as compared to healthy subjects.

 Abstract

The present study deals with the synthesis of silver nanoparticles using the leaf broth of Merremia tridentata (L) Hall. f. (Family: Convolvulaceae). The leaf broth was prepared and resuspended in aqueous solution of silver nitrate and it is known as reaction medium. This reaction medium was kept in an incubator cum shaker with 250 rpm at 270C for 24 hrs to reduce the silver nitrate in to silver nanoparticles. The colour change in reaction mixture (Pale yellow to dark brown colour) was observed during the incubation period. The formation of silver nanoparticles in the reaction medium that enables to produce colour change due to their specific optical properties. The formation of silver nanoparticles was evaluated and characterized by UV-Visible Spectroscopy, Fourier Transform Infra-Red (FT-IR) Spectroscopic analysis and X-ray diffraction (XRD) analysis. It is evident that the synthesized silver nanoparticles are capped by biomolecules which are responsible for reduction of silver ions. Energy Dispersive X-Ray (EDX) analysis and Scanning Electron Microscopy (SEM) confirmed the formation of silver nanoparticles. This type of phyto-mediated synthesis appears to be cost effective, ecofriendly and easy alternative to conventional, physical and chemical methods of silver nanoparticle synthesis.
