Influence of Naturally Originated Jute on the Fabrication & Mechanical Properties of Jute/Polyester Hybrid Composite
Get PDFJute-Polyester reinforced Composited is fabricated through this research. The development of composite materials based on the reinforcement of two or more fiber types in a matrix leads to the production of hybrid composites. Jute cloth Polyester resin were used to prepare the Jute/Polyester composites by hand lay-up and heat press molding techniques and their mechanical properties behaviors were evaluated for different stacking sequences. In Jute/polyester mechanical properties such as tensile strength, bending properties and impact strength increase with the increases of stacking sequences. Water uptake (%) of this composite demonstrates that water absorption rate is initially higher for jute/polyester composite and at a stage it becomes steady (31.11%). Soil degradation test of all types of Jute/polyester were evaluated and the deterioration of the mechanical properties revealed for jute/polyester composites showed the higher degree but retained major portion of its original integrity and depicts the hybrid

Comparative Evaluation of Success and Survival Rates of Two Piece Implant placed Immediately or Delayed into Extraction Site: A Clinico-radiological Study
No full textThe Purpose of present study was to compare and evaluate the success and survival retes of two piece implants placed immediately or delayed into extraction socket. Total Fourteen implant sites which were free of active infection were selected and were divided in 2 groups depending on the time of implant placement. In Group-I, seven implants were placed immediately after extraction and in Group-II, seven implants were placed after minimum 3 months of extraction. Clinically, modified plaque index, bleeding index, gingival index, probing depth and implant mobility were assessed preoperatively as well as postoperatively at 1 month, 2 month and 3 months. Radiologically, marginal bone levels and radiolucency around the implants were observed. Immediate group showed better results than delayed group in respect to modified plaque index, mean probing depth and implant mobility. While better results were observed in delayed group with respect to bleeding index, gingival index and mean bone loss. Periapical radiolucency was not observed in any of the sample at various follo up intervals. It was concluded that both groups (group I and group II) showed equal results but delayed group showed slightly better results than immediate group
Uncommon Oral Manifestations of Neurofibromatosis Type I – A Case Report
Get PDFNeurofibromatosis type I is an autosomal dominant genetic disorder. It is related to a mutation in the long arm of chromosome 17; however, it shows variable penetrance and about half of the cases have no family history of the disease. These patients present skin lesions such as cafe-au-lait spots, multiple neurofibromas, bone malformations, and central nervous system tumors as well. Diagnosis of NF-I NF-II is based on clinical criteria. It is progressive in nature and one of its unique characters is the diversity of clinical expression from one patient to another and even within a family. NF-I also presents with certain oral manifestations which confers to the dentists a major responsibility for accurate diagnosis and report of the disease. We, herein, report a case of 35 year old female patient who was diagnosed incidentally for NF–I with unusual oral manifestations such as large tongue mass and hypo-plastic ramus body of the right side of mandible
Prevalence of Saprolegniasis in Fish Farms in Gboko, Nigeria
Get PDFSaprolegniasis is a fungal disease of fish and fish eggs, caused by the saprolegnia species commonly referred to as “Water molds”. Fish diseases constitute one of the major problems militating against the growth of aquaculture, especially in the tropics. Among the many pathogens of fish, is saprolegnia which has been reported to be the major fungus infecting fresh water fish. There is generally, perceived high occurrences of saprolegniasis in fish farms in Gboko. However, there is no data on the prevalence of the disease. The aim of this study is to determine the Prevalence rate of Saprolegniasis in fish farms in Gboko, Nigeria. Fifty four fish farms in Gboko, Benue state, where studied to determine the prevalence rate of Saprolegniasis. Data for the study was collected using a well-structured questionnaire and observations. The prevalence rate of Saprolegniasis in the study area was found to be 61.11% at the time of the study.

Many colorants, whether natural or synthetic, possess some inherent functions in addition to their coloring attribution. These properties can be utilized in textile dyeing processes to bring the particular functions to textiles in various textile industries. In other words, dyeing textiles with these colorants can combine dyeing with having a functionality finishes, a greener process than current separated wet treatments in terms of reduced generation of waste water and consumption of energy. Recently there has been a revival of interest in the use of natural dyes in textile coloration. This is a result of the stringent environmental standards imposed by many countries in response to the toxic and allergic reactions associated with the use of synthetic dyes. The aim of this review compilation is to give an overview on the main compounds used today for coloration of textile materials seeking for as antibacterial functionalization based on an evaluation of scientific publications, potential perspective of microbes on the environment and human health were considered
Improving the Fastness Properties of Cotton Fabric through the Implementation of Different Mordanting Agents Dyed with Natural Dye Extracted from Marigold
Get PDFExtraction of natural dyes for the coloration of Textile substrate is one the most important research area to the researchers. It is tried to extract the natural dyes from marigold flower through using the different kinds of mordanting agents. In this research, a particular source is used for dyes extraction. Before the extraction Patel of the marigold flower was extracted and dried on sunlight, subsequently dried in room temperature due to preserve the natural colorant. The natural dyes were extracted by boiling the above substrates in water without any chemicals. As mordant, Potash Alum [K2Al2(SO4)3.24H2O], Ferrous Sulphate(FeSO4),Copper Sulphate (CuSO4),Nickel (II) Sulphate (NiSO4),Potassium Dichromate (K2Cr2O7),Stannous Chloride(SnCl2) were used. The mordanting procedures were followed same for all the experiments. The treatment runtime was 60 minute at 100oC. After mordanting each sample fabric was kept for 24 hours for conditioning and then the dyeing was done. But as there is no particular dyeing method for natural dyeing so it is followed some trial and some convenient methods were made after trial for several times. Mordanted samples were wet out in cold water before dyeing. During dyeing some salt or soda was added to observe the effects through the Runtime 60 minutes at 60oC. After dyeing samples were cold rinsed and soaping was done and dried with hot air dryer. Finally the color fastness like Color fastness to wash, Color fastness to perspiration/saliva, Color fastness to water, Color fastness to rubbing and Color fastness to light were checked and found satisfactory result
Occurrence of various ingredients in the lake environments at Stornes Peninsula, Ingrid Christenson Coast, East Antarctica
Get PDFThe Larsemann Hills is an ice-free area of approximately 50 km2, located halfway between the Vestfold Hills and the Amery Ice Shelf on the south-eastern coast of Prydz Bay, Princess Elizabeth Land, East Antarctica (69o30’S, 76o19’58”E). The area consists of two major peninsulas Stornes and Broknes, four minor peninsulas, and approximately 130 near shore islands. There are more than 150 lakes on different peninsulas and islands.Surface water samples were collected from two lakes on Stornes Peninsula during 30th Indian Scientific Expedition to Antarctica (ISEA) in mid-January 2011 and analysed for the physico-chemical parameters, major elements and trace metals. Lake waters were slightly acid, free from any colour, odour and turbidity, with dissolved oxygen close to saturation. Total dissolved solids were rather similar in both lakes, up to 71 mg/l and the dominant elements were Cl and Ca. Several minor and trace elements were very low or under detection limits. Total organic carbon was ca 0.7 mg C/l in both lakes and PO4 was at 0.002 mg/level in one lake. Several pesticide residues were all under detection limits as well as alpha and beta radiation activities. Total bacterial count was 1.6×103cfu/ml in lake ST-2 and lower in other lake while psychrophilic bacterial count was 1.6×102cfu in the former lake. Also a Pseudomonas spp. was detected in the ST-2 lake sample
