It has increased applications in diverse area for the development of new materials at nanoscale levels. Synthesis of nanoparticles using biological methods is referred as greener synthesis of nanoparticles. Green synthesis provides advancement over chemical and physical method as it is cost effective, environment friendly, and safe for human therapeutic use. Stingless bees are highly social (eusocial) insects which populated the tropical earth 65 million years ago longer than honey bees. Among the most common uses of stingless bee honey are to treat stomach disturbance, cough, tonsillitis, sore throat, stomach and intestinal ulcers, cold, disease of the mouth, mucus membrane, and as a wound dressing due to its antimicrobial activity. Stingless bees honey were used to for the green synthesis of silver nanoparticles. Antimicrobial activity of the green synthesised nanoparticles were tested used agar diffusion method against Escherichia coli (E. coli), Pseudomonas aeruginosa, Staphylococcus aureus, Salmonella typhi and Klebsiella pneumoniae. The results showed that stingless bee honey could be effectively used for the synthesis of silver nanoparticle. The synthesized silver nanoparticles shows antibacterial activity on both Gram positive and Gram negative bacteria. This biosynthesis of nanoparticles is cost efficient, pollutant free and simpler to synthesize.

Available in PDF, EPUB and Kindle. Book excerpt: Bachelor Thesis from the year 2013 in the subject Biology - Miscellaneous, grade: M.Sc., , course: Biotechnology, language: English, abstract: Research and analysis of nanoparticles (NPs) synthesis and their biological activities has been expanded significantly in the recent years. The agents used for nanoparticles (NPs) synthesis are of organic (mainly carbon) and inorganic (metal ions like silver and gold) origin (Singh et al., 2010). Among these, silver (Ag) is the most preferred NPs synthesis agent due to its reported use in medical field as best topical bactericides from ancient times (Lavanya et al., 2013). The stable silver nanoparticles had been synthesized by using soluble starch as both the reducing and stabilizing agents (Shrivastava et al., 2012). So the concern of scientific community shifted towards ecofriendly, natural and cheaper method of NPs synthesis by using microorganisms and plant extracts (Mohanpuria et al., 2008). The use of plant materials for silver nanoparticles (AgNPs) is most popular due to its potential biological activities, easy availability and faster rate of synthesis there by cutting the cost of NP's synthesis (Huang et al., 2007 and Salam et al., 2012). The nanoparticles had been clinically used for infection, vaccines and renal diseases (Malhotra et al., 2010). The plant extract of petals of herbal species like Punica granatum, Datura metel (Chandran et al., 2011) and stem extracts of Svensonia hyderobadensis (Linga et al., 2011) had been effectively used for AgNPs synthesis and investigated for their antimicrobial activities. Nanoparticles could be synthesized by various approaches like photochemical reactions in reverse micelles (Taleb et al., 1997), thermal decomposition (Esumi et al., 1990), sonochemical (Zhu et al., 2000) and microwave assisted process (Santosh et al., 2002 and Prasher et al., 2009). Nanocrystalline silver particles have found tremendous applications in the field of high sensitivity biomolecular detection and diagnostics (Schultz et al., 2000), antimicrobials and therapeutics (Rai and Yadav., 2009 and Elechiguerra et al., 2005) and micro-electronics (Gittins et al., 2000). Acacia auriculiformis A. Cunn. is an exotic species that can survive in degraded lands in Thai savanna (Badejo et al., 1998). Besides its high adaptability in degraded savanna areas, A. auriculiformis is known for its nitrogen fixation property (Sprent and Parsons, 2000) enriching macrofaunal composition (Mboukou-Kimbatsa et al., 1998), low allelopathic effects (Bernhard-Reversat et al., 1999) and ability to pump nutrients from the subsoil (Kang et al., 1993).

Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the perceptions and sketches, geological background, materials and coastal processes of the East Coast of India. It also suggests strategies for effectively managing natural coastal processes in these areas. India has a coastline of about 7,516 km with a variety of coastal extensions, which developed at different time scales, producing permanent variations in the morphologies of the coastal areas through hydrodynamic, fluvial, aeolian and terrestrial processes. The book focuses on the Balasore coast, an area drained by three main rivers (the Subarnarekha, the Dugdeugi and the Burahbolong), which impacts the coastal morphodynamic processes of the area and accounts for their multifaceted nature. Large drops or increases in the sediment supply within a short time span or over prolonged periods cause shoreline shifting. Eight satellite images from 1975, 1980, 1990, 1995, 2000, 2005, 2010 and 2013 were used to measure the shoreline dynamics, and a reference line was established using first order polynomial model with base data with 0.5 pixel root mean square error (RMSE) accuracy. The end point rate (EPR) model was adopted for estimating the future position of the shoreline. In order to assess the beach morphodynamics, the coastal modeling system (SMC) was used, which incorporates with a series of appliances and numerical models structured consistent with the space and time scale of the different dynamics affecting the littoral and beach morphology based on diverse thematic and reference documents. This study employed short-term analysis using the MOPLA module of the SMC system, which consists of three attached modules: the wave transformation module (Oluca), the depth-averaged currents module (Copla) and the sediment transport and morphological evolution module (Eros). The shoreline dynamics findings show that the magnitude of erosion is higher in the northern part of the coastline in the left bank area of the Subarnarekha river estuary and in the estuarine part of the Dugdugi and Burahbalang rivers. The southern part of the shoreline near Rasalpur and Joydevkasba is relatively stable, and the study suggests that the current shoreline shift trend will continue in the future. The SMC model indicates that the wave height, significant wave height, current velocity and the potential transport of sediment at the Kirtaniya study point are high, while at Choumukh they are low and at the Rasalpur study point they are intermediate.

Book excerpt: New Zealand's manuka honey is known around the world. It fetches extremely high prices, and beekeepers do everything in their power to produce as much of it as they can. Wound dressings containing manuka honey are used in leading hospitals, and it has saved the lives of patients infected with disease-causing bacteria that are resistant to standard antibiotic drugs. In so doing, it has forced the medical profession to re-think its position on the therapeutic properties of natural products. This book chronicles the remarkable 'rags-to-riches' story of manuka honey, as seen through the eyes of a beekeeping specialist who watched it unfold from the very beginning. It's a great science tale of an unassuming university lecturer and his hardworking lab assistant who found something totally unexpected in a product everyone had written off. And it's an entertaining account of the way that simple discovery magically caught the international media's attention, helping some enterprising New Zealanders with a love of bees to develop manuka honey-based products and take them to the rest of the world. The book describes the remarkable antibacterial and therapeutic properties of manuka and the range of uses it has.

Available in PDF, EPUB and Kindle. Book excerpt: Immunity in insects is different from immunity in vertebrates. Insects lack immunoglobulins even though they are capable of reacting against foreign components with effective defense mechanism. There has been a marked advancement in most of the fields of science in the past two decades. Insect immunity is also one of them. It is a developing subject which is now established as a new branch in insect study. This treatise is an attempt to compile meaningful articles of leading workers in this field, nevertheless we do not claim that leadership in insect immunity is by any means restricted to them. The idea is to provide a vibrant description of various aspects of "Insect Immunity". With the rapid development of the subject, it is difficult for any one author to discuss all the aspects of an area in a limited number of pages, even then they have done their utmost to include the entire development of the subject in their articles. The treatise deals with insect haemocytes, their population, isolation and role in defense mechanism, humoral encapsulation, inducible humoral antibacterial immunity, cellular immune reactions, role of endocrines, role of prophenol oxidase system in cellular communication, haemagglutinins and impact of parasite on insect immune system. Some topics could not be covered because experts in those area though willing could not complete their commitment within time limits.
