Corresponding Author: *Madhukiran.J ABSTRACT: - The usage of natural fiber reinforced composites is growing at a faster rate and is actively being considered as an alternate material for synthetic fiber. In the present work an attempt has been made to fabricate the sisal-coir fiber randomly oriented hybrid composites and to evaluate the mechanical properties such as tensile strength and flexural strength. Three types (sisal-coir) of hybrid laminate and two pure laminate composites are fabricated using manual layup technique. Epoxy (Ly556 and HY951) resin is used as matrix material in the present work. The specimens are prepared according to ASTM standards and the experiments were conducted on an universal testing machine (UTM).From the experimental results, it has been observed that the sisal-coir fiber hybrid composites exhibited superior properties when compared to pure composites. Keywords:- Coir & Sisal fibers, Epoxy, Hybrid polymer matrix composite, Hand layup. -

Fiber logs composed of other sturdy biodegradable materials may function equally as well. Applications for coir logs occur in many streambank, wetland and upland environments. The log provides temporary physical protection to a site while vegetation becomes established and biological protection takes over. The logs can provide a substrate for plant growth once the log decay process starts and protects native and newly installed plants growing adjacent to the log. -

Among different types of reinforced composites natural improving the strength of various applications in current trends. fibre reinforced polymer composites were commonly used Based on these trends the combination of natural jute/coir fiber due to its availability, low density, cost and improved energy hybrid composite of different size of fiber length was examined in recovery [3, 4]. Since natural fibre are classified as jute, this study. The hybrid fiber composite was fabricated by banana, coconut, palm fibres, etc. Increased mechanical compression moulding technique by impregnating jute fiber and coir fiber with unsaturated polyester resin, Cobalt octoate and property simultaneously increases the fibre weight index methyl-ethyl-ketone peroxide as accelerator and catalyst.

Raffia Palm Fibre, Composite, Ortho Unsaturated Polyester, Alkali Treatment
American Journal of Polymer Science 2014, 4(4): 117-121 DOI: 10.5923/j.ajps.20140404.03 The Effect of Alkali Treatment on the Tensile Behaviour and Hardness of Raffia Palm Fibre Reinforced Composites D. C. Anike1,*, T. U. Onuegbu1, I. M. Ogbu2, I. O. Alaekwe1 1Department of Pure and Industrial Chemistry, Nnamdi Azikiwe University Awka, Anambra State, Nigeria 2Department of Chemistry Federal University Ndufu-Alike, Ikwo Ebonyi State, Nigeria Abstract The effects of alkali treatment and fibre loads on the properties of raffia palm fibre polyester composite were studied. Some clean raffia palm fibres were treated with 10% NaOH, and ground. The ground treated and untreated fibres were incorporated into the ortho unsaturated polyester resin. The treated and the untreated fibre composites samples were subjected to tensile tests according to ASTM D638 using instron model 3369. The microhardness test was done by forcing a diamond cone indenter into the surface of the hard specimen, to create an indentation. The significant findings of the results showed that alkali treatment improved the microhardness and extension at break at all fibre loads, better than the untreated fibre composites, with the highest values at 20% (14.40 and 3.47mm for microhardness and extension at break respectively). Tensile strength, tensile strain and modulus of elasticity also improved for alkali treated fibre composites, except in 5% and 20% for tensile strength, 15% for tensile strain, and 15% and 20% for modulus of elasticity, compared to the corresponding fibre loads of untreated fibre composites.

Cannabis As Plant and Product
1 Cannabis as Plant and Product Marijuana is subject to numerous misconceptions and con- fusion. There is disagreement on some basic issues, such as how the cannabis plant grows, how it interacts with the body, where it comes from, and how long it has been in use. Before jumping into a discussion of marijuana policy, it is important to dispel these misconceptions regarding the plant and its products. Some popular misconceptions include that marijuana is easy to grow, that it can grow under almost any conditions, and that it’s pretty much the same everywhere. You grow it, pluck its flowers, dry them, wrap them in rolling paper, and smoke it, and there you have it, your weed, or pot, or Mary Jane. In reality the cannabis plant is biologically complex, and the production of marijuana is not as simple as many people believe. 9 Hudak_Marijuana 2nd Ed_a,b_i-xiv_1-252.indd 9 5/11/20 9:51 AM 10 MARIJUANA In addition, marijuana has changed over time with in- novations in growing, harvesting, and generating products. Marijuana is no longer something you pack into a bowl, roll in a joint, smoke in a bong, or lace into some brownies. It’s now a diverse consumer product available in many forms. The Cannabis Plant Members of the Cannabis genus are leafy, flowering plants that are native to Central Asia but have been transported and grown throughout the world. The plant has been around for millions of years in some form and has been used by humans for at least 5,000 years.1 It tends to be robust and grows effectively in both natural and controlled agricultural settings. -

Blunts and Blowt Jes: Cannabis Use Practices in Two Cultural Settings
Free Inquiry In Creative Sociology Volume 31 No. 1 May 2003 3 BLUNTS AND BLOWTJES: CANNABIS USE PRACTICES IN TWO CULTURAL SETTINGS AND THEIR IMPLICATIONS FOR SECONDARY PREVENTION Stephen J. Sifaneck, Institute for Special Populations Research, National Development & Research Institutes, Inc. Charles D. Kaplan, Limburg University, Maastricht, The Netherlands. Eloise Dunlap, Institute for Special Populations Research, NDRI. and Bruce D. Johnson, Institute for Special Populations Research, NDRI. ABSTRACT Thi s paper explores two modes of cannabis preparati on and smoking whic h have manifested within the dru g subcultures of th e United States and the Netherlan ds. Smoking "blunts," or hollowed out cigar wrappers fill ed wi th marijuana, is a phenomenon whi ch fi rst emerged in New York Ci ty in the mid 1980s, and has since spread throughout th e United States. A "bl owtj e," (pronounced "blowt-cha") a modern Dutch style j oint whi ch is mixed with tobacco and in cludes a card-board fi lte r and a longer rolling paper, has become th e standard mode of cannabis smoking in the Netherl ands as well as much of Europe. Both are consid ered newer than the more traditi onal practi ces of preparin g and smoking cannabis, including the traditional fi lter-less style joint, the pot pipe, an d the bong or water pipe. These newer styles of preparati on and smoking have implications for secondary preventi on efforts wi th ac tive youn g cannabis users. On a social and ritualistic level th ese practices serve as a means of self-regulating cannabi s use. -

Abstract: India is the largest coir producer in the world accounting for more than 80 per cent of the total world production of coir fibre. The coir sector in India is very diverse and involves households, co-operatives, NGOs, manufacturers and exporters. This is the best example of producing beautiful artifacts, handicrafts and utility products from coconut husks which otherwise is a waste. The coir industry employs more than 7.00 lakh persons of whom a majority is from rural areas belonging to the economically weaker sections of society. Nearly 80% of the coir workers in the fibre extraction and spinning sectors are women. The survey was conducted on the basis of convenience sampling method. For developing a sample design, totally 100 respondents were selected for this study. The data have been analyzed to verify the hypotheses framed in line with the objectives of the study.
