Majority of microbial infections occurring in the human body are attributed to be biofilm-mediated. Biofilms formations in industrial settings are associated with many problems. Formation of biofilm is controlled by environmental factors. This study is carried out to determine the biofilm formation in Serratia marcescens under different environmental condition. Biofilm assay in nutrient medium by microtitre plate methods under different test conditions were performed. Using a microplate assay with crystal violet staining, we examined biofilm formation by 30 strains in nutrient broth with different temperatures (fridge temperature, Room temperature and 37◦C), at different pH (4.5, 7.0 and 8.5) and with varying concentrations of sodium chloride (0.5%, 1% and 2%). The synergistic effect on biofilm formation was observed for temperature, pH and salt concentration. The strains produced more biofilm at fridge temperature than at RT and 37◦C. Biofilm production at pH 4.5, 7 and 8.5 was comparable but significantly higher at pH 4.5. This study also demonstrated the influence of NaCl on biofilm formation.

The dental restorative materials represent a unique class of biomaterials with some restrictions in physical, mechanical and biological properties like biocompatibility, aesthetics, and ultimate material properties. Fortunately, the dental restorative materials have been the focus of a great deal of research in recent years with the goal of improving restoration performances by changing the initiation systems (composite), fillers (GIC) and by developing novel polymerization strategies (composites) etc. Here, we review the recent modifications made in different dental restorative materials.

Cyphostemma setosum is a traditional medicinal climber, distributed in Palani hills, the Western Ghats, Tamil Nadu, India. In this region, the puliah tribal community is using this species more commonly to control type II diabetics. As there is no work in this line, the present study was carried to investigate the in vitro antidiabetic activity of C. setosum in terms of the level of inhibition of α-amylase and α-glucosidase as influenced by methanolic extract of aerial parts of this species. The results showed that the extract inhibits the α-amylase and α-glucosidase enzymes very considerably and also exhibited the IC50 values 123.11±2.34 and 279.69±4.21µg/mL respectively. The study evidenced strongly that the probable inhibition of these two enzymes may lowers the blood glucose levels. Thus this species, C. setosum is claimed to have antidiabetic activity and further studies on in vivo models are in most needed.

Health is the essential part of human that individual has to feel, perceive and act effectively. And it is required to provide correspondent ways for proper health care delivery in real time manner. The arrival of new technologies especially the Internet of Things (IoT) Strengthen the health care system through Wireless Sensor Network (WSN). In the current health care environment the IoT enables to connect different stakeholders in the health care system like patients, physicians, hospital, emergency unit and patient well-wishers etc. regardless of their current location. The deploying of sensory devices and microcontrollers into health care system fetches an e-health care system. The existing health care system is usually unacceptable due to high operational cost and inconvenience user interface provided to the user. This paper focuses on implementing an e-health care system that collects the health data and processes it and performs the appropriate analysis to the collected data that enables to take the future decisions about individual patient by tracking and monitoring theirs previous health record.

Hope and despair are two consept that commonly used in the human health. hope is a concept that positively affect the health of the individual. However, despair has a negative impact on an individual's health.

Sign Language is the mode of communication among the deaf and dumb. However, integrating them into the main stream is very difficult as the majority of the society is unaware of their language. So, to bridge the communication gap between the hearing and speech impaired and the rest in Bangladesh, we conducted a research to recognize Bangla sign language using a computer-vision based approach. To achieve our goals we used Artificial Neural Networks to train individual signs. In the future, this research, besides helping as an interpreter, can also open doors to numerous conveniently other applications like sign language tutorials or dictionaries and also help the deaf and dumb to search the web or send mails more.

The present study prominences on the customer satisfaction in service quality aspects among public sectors banks and private sectors banks in coimbatore city. The major objectives of this study are to identity the expectations (E) of consumers concerning banking facility, to discover perception (P) of consumers concerning service excellence of banks and to associate service excellenceslits (P-E) in public sectors banks and private sectors banks in Coimbatore city. Empirical method adopted with the basic arrangements of SERVQUAL instruments to measure the service Quality of banks. A grouping of convenience and duster sampling techniques were cast-off to select respondents from consumers of two public sectors banks (SBI & Canara Bank) and two private sectors (ICICI & HDFC Banks) in Coimbatore city. Arithmetic mean was calculated with the assistance of SPSS to examine the dates. The outcomes of this study indicate that the service gap is lesser in private sectors banks when compared to public sectors banks which shows that the private sectors bank consumers were extremely satisfied when compared with public sectors bank consumers. Aspects more subjugated by private sectors banks throughout the whole SERVQUAL excluding in the circumstance of assurance in which the public sectors banks have healthier results. Both the type of banks must find resolutions to reduce the prevailing service gaps and increase their customer satisfaction. Public sectors banks in particular increase their performance in order to uphold and preserve its market share in Coimbatore city.
