A simple and eco-friendly method for the synthesis of green nanoparticles (NP's) using an aqueous extract of Mirabilis jalapa fresh leaves as bioreductant is reported.
Objectives: The present investigation is to synthesize silver nanoparticles using aqueous extract of plant Mirabilis jalapa and to evaluate its antibacterial activity using different bacterial species.
Methods: The particles were preliminarily confirmed by the change in colour. The prepared green nanoparticles were well characterized using UV-Vis spectroscopy and FTIR. The antibacterial activity of aqueous extract, silver nanoparticles and antibiotic control were carried by well diffusion method.
Result: The change in colour from colorless to brownish color indicates the formation of silver nanoparticle. The UV -Vis spectroscopy peak at 440 nm confirms the silver nanoparticles in the suspension. The FTIR spectrum of both plant extract and AgNPs also reveals the reduction. The phytoconstituents which were responsible for reduction are conformed through preliminary phytochemical analysis. The potential application of biosynthesized nanoparticles as an antibacterial agent against selected pathogens were evaluated by welldiffusion method. Except E.coli all other organisms showed sensitivity towards 20μl and 10 μl of AgNPs, measured from the zone of inhibition. Similarly control and aqueous extract showed some activity towards the tested organisms.
Conclusion: Thus the antibacterial findings provide strong evidence that the synthesized silver nanoparticles of Mirabilis jalapa were effective against human pathogens.

The main objective of the variable damper controlled vehicle suspension system is to reduce the discomfort identified by passengers which arises from road roughness and to increase the ride handling related with the rolling, pitching and heave movements. This imposes a very fast and accurate variable damper to meet as much control objectives, as possible. The method of the proposed damper is to reduce the vibrations on each corner of vehicle by providing control forces to suspension system while travelling on uneven road. Numerical simulations on a full vehicle suspension model are performed in the Matlab Simulink toolboxes to evaluate the effectiveness of the proposed approach. The obtained results show that the proposed system provides better results than the conventional suspension system.Keywords

Active suspension systems have been used in the recent years as they provide better ride comfort, road handling and safety. The effect of vehicle vibration caused by road roughness is effectively reduced by active suspension system which plays an important role in improving the vehicle performance indices. The application of active suspension system is limited because it consumes high amount of energy. From the point of energy saving, a regenerative active suspension system is designed and its working principle with two modes switched in different conditions was implemented. In this implementation scheme, operating electric circuits are designed based on different working status of the actuator and power source. In the first stage an electromotor mode in which an active suspension system uses a linear electric actuator controlled by constrained PID controller. In the generator mode, under certain circumstances using linear motor as actuators enables to transform mechanical energy of the car vibrations to electrical energy and accumulated to charge the energy-storage capacitor and fed back into the power source when needed.Keywords

In the chassis assembly shop, there are instances when the rear axle oil was not filled. During the period from January to December, there were ten such instances that were reported. Out of the 10 cases, 6 cases seized after handing over the vehicle to the customer and 4 cases were identified when the vehicles left the assembly process. The reason for the seizing of the trucks was predominantly due to the absence of the oil in the rear axle or in some cases, due to the discrepancy that occurred. This problem can be rectified by introducing the concept of interlocking, wherein the conveyor stops from proceeding to the next stage in case the rear axle oil is not filled. To prevent any further chances of error, a system was suggested where a code is scanned, which gives details of the bill of materials used to assemble the truck. This bill of material includes the axle model number which is cross referenced with a traceability matrix to determine the quantity of oil required and confirming the oil filling process with a sticker.Keywords

Introduction: Green synthesis of silver nanoparticles has been increasingly preferred nowadays over physical and chemical approaches. In this study, silver nanoparticles are synthesised using nutmeg oleoresin at room temperature. Materials and methods: Nutmeg oleoresin mediated silver nanoparticles was prepared using 1 milli molar of silver nitrate. The prepared nanoparticles were confirmed using UV-vis spectrophotometer. Different concentrates of the synthesised nutmeg oleoresin mediated silver nanoparticles was tested against Streptococcus mutans and Enterococcus faecalis using agar well diffusion method and MIC will be determined. Results: It has been observed that the anti bacterial effect of the prepared AgNP’s was almost similar against all the organisms used in the study with a maximum ZOI against Pseudomonas sp. and minimum ZOI against Enterococcus faecalis. It has also been observed that the antibacterial activity of the AgNP’s increased with increasing concentration. Conclusion: The synthesised nutmeg oleoresin mediated AgNP’s showed tremendous antimicrobial activity against the oral pathogens: Staphylococcus aureus, Streptococcus mutans, Enterococcus faecalis and Pseudomonas sp. with increased activity against Pseudomonas sp. Thus novel biological approach for the synthesis of AgNP’s using nutmeg oleoresin is a eco-friendly method and can be used in the development new drugs against oral pathogens.

Background: Candida albicans is known to cause a variety of diseases like oral candidiasis, vaginal candidiasis, invasive candidiasis etc. Although there are anti-fungal drugs in use for the treatment of these diseases, alternative medicine is required for their prophylaxis and improved prognosis. For this purpose, silver nanoparticles (Ag-NPs) can be used as antifungal agents. They are already in use as anti-microbial and anti-fungal agents in agriculture and can potentially be used as targeted drugs for the human body. The aim of this research is to study the anti-fungal efficacy of silver nanoparticles synthesised using a herbal formulation of Androgrophis paniculata and Moringa olifera against Candida albicans.
Materials and Method: Herbal formulation was created using the leaves of Androgrophis paniculata and Moringa olifera. Silver nitrate solution was added to this and the solution was transferred to an orbital shaker for silver nanoparticle preparation. The powder of Ag-NPs was created. The bioreduction of pure AgNO3 was characterized by UV-visible spectroscopy. Candida albicans was isolated using serial dilution method and a fresh fungal suspension was dispersed on Rose Bengal agar. Both disc diffusion and agar well diffusion methods were used. Different concentrations of Ag-NPs (50, 100 and 150 microliter) were incorporated into the wells, discs, and plates and these were incubated at 37°C for 24 hours. The antifungal agents were used as positive control. Zone of inhibition was recorded in each plate. Proper documentation methods were used.
Results: Colour change was seen after the preparation of silver nanoparticles. The peak in UV-vis spectroscopy was seen to be at 400 nm. The zone of inhibition was seen to increase with an increase in the concentration of Ag-NPs in the agar wells. The plate dispersed with the highest concentration of Ag-NPs had the lowest cultural population.
Conclusion: The herbal synthesis of Ag-NPs is highly eco-friendly and should be practised more than chemical synthesis of the same. The antifungal activity of Ag-NPs was comparably effective to the control used and in the future they can be administered as an antifungal drug for the prophylaxis and treatment of various types of Candidiasis.

Background: When left unchecked, dental pathogens cause chronic diseases like periodontitis and dental caries that lead to the irreversible loss of tooth structure. However, with proper prophylactic measures, we can inhibit the excessive proliferation of pathogenic oral flora. The aim of this study was to examine the plausible antibacterial potential of silver nanoparticles synthesized using neem and Aloe vera against four dental pathogens - Streptococcus mutans, Staphylococcus aureus and the Enterococcus and Pseudomonas species.
Materials and Method: Leaves of Azadirachta indica and Aloe vera were made into a filtered herbal formulation. A metallic solution of silver nitrate was added to it and the conjunction was kept in an orbital shaker for the synthesis of nanoparticles. After centrifugation, the resultant pellet was powdered. The agar well diffusion method was used to determine the antibacterial efficacy of Ag-NPs. Fresh bacterial suspensions of Staphylococcus aureus, Streptococcus mutans, the Enterococcus and the Pseudomonas species were dispersed on the surface of Muller-Hinton agar containing plates. Ag-NP concentrations of (25, 50 & 100) μl were incorporated into the wells and the plates were then incubated at 37°C for 24 hours. Antibiotics were used as a positive control. The zone of inhibition was recorded for each plate
Results: A colour change was observed after the synthesis of Ag-NPs. The prepared particles were then characterised by a peak seen at 425 nm in UV-vis-spectroscopy. The zone of inhibition increased in size with an increase in Ag-NP concentration. They increased in the order of: Staphylococcus aureus, the Enterococcus species, Streptococcus mutans and the Pseudomonas species - with Staphylococcus aureus being the smallest and the Pseudomonas species being the largest.
Conclusion: Ag-NPs synthesized using neem and Aloe vera is an effective antibacterial agent against Streptococcus mutans and the Pseudomonas species. It is eco-friendly, rapid, easy to synthesize and effective. These Ag-NPs are a non-toxic solution for multiple-drug resistant bacteria.
