Metaphor on Three Poems, Invictus, The Road Not Taken and Dreams
This study presents an analysis of metaphor on three poems, Invictus, The Road Not Taken and Dreams. The objective of this study is: to find out the types and meaning from three poems. The analyses were based on the combination of Lakoff and Johnson’s theory (2003), and Konvecses’s theory (2010) to find out the kind’s of metaphor and meaning of Invictus, The Road Not Taken, and Dream poems. What is the kind’s of metaphor and meaning of line on Invictus, The Road Not Taken, and Dream poems. In this study, the researcher will use descriptive qualitative research. The findings of this study were directed to know what is the kind’s of metaphor and meaning of Invictus, The Road Not Taken, and Dream poems. The result of this research is to show that the kind’s of metaphor and the meaning of poetr

Response and Bioaccumulation Potential of Boerhavia diffusa L. Towards Different Heavy Metals
Effect of different concentrations of heavy metals such as Cadmium, Chromium, Mercury and Leadwas studied by cultivating rooted propagules of Boerhavia diffusafor a period of twenty days in Hoagland nutrient medium artificially contaminated with known concentration of those heavy metal ions. Concentrations of the metals selected to impart visible symptoms of growth retardation and to permit survival for prolonged period are 30µM cadmium chloride (CdCl2), 400 µM potassium dichromate (K2Cr2O7), 10 µM mercuric chloride (HgCl2), and 600 µM lead acetate (CH3-COO)2Pb. More or less uniform growth performance was shown by the plants irrespective of the differences of concentration of the heavy metals. However, parameters such as root - and stem length, stomatal - and tolerance index varied among the treatments. Significant differences were observed in the heavy metal accumulation potential among metals and between plant parts such as root, stem and leaf and the pattern was dependent on growth period
ROLE OF EPIGENETIC MECHANISMS IN VARIOUS CANCER THERAPIES
Epigenetics play a role not just in the normal functioning of the cell and its development, but also in diseases like neurological diseases and cancer. Epigenetic therapies can help to resolve non-identical problems of these pathophysiological conditions. Cancer is a complex disease with both genetic and epigenetic origins. The importance of epigenetics in cancer has been identified, and the field has emerged rapidly in recent years. Epigenetic and genetic alterations contribute to the initiation and progression of cancer. Epigenetic modifications introduced genetic changes, and usually occur at an early stage in development of a neoplasm, but may also be involved in its invasion and spread. Recent technological advances in genetics and epigenetics offer a better understanding of the underlying epigenetic alterations during initiation and in the progression process of the human tumors
Distribution of Bio-accumulated Cd and Cr in two Vigna species and the Associated Histological Variations
In nutrient culture experiments, bioaccumulation and anatomical effects of cadmium (CdCl2 - 20μM) and chromium (K2Cr2O7 - 600 μM) on the structure of root and stem was studied by histochemical and analytical methods in Vigna radiata and Vigna unguiculata. Each metal exerted specific influences on the anatomy of various tissues in root and stem. Histochemical localisation of cadmium and chromium was observed in the stained sections of root and stem. Atomic Absorption Spectrophotometric study revealed maximum accumulation of cadmium and chromium in the root tissue as compared to shoot with significant variation among the species. Abundant occurrences of densely stained deposits of chromium were seen in the root stelar region of V. unguiculata and to a lesser extend in V. radiata. Cadmium accumulation in V. radiata was comparatively more than that of V. unguiculata. The findings also revealed that the accumulation pattern of cadmium and chromium varies between species and hence is species specific
Fabrication of Low-Roughness Au/Ti/ SiO2/Si Substrates for Nanopatterning of 16-Mercapto Hexadecanoic Acid (MHA) by Dip-Pen-Nanolithography
Silicon based low-roughness Au/Ti/SiO2/Si substrates were fabricated using standard IC fabrication
processes. Evolution of surface roughness during substrate fabrication process was studied. Fabrication
process steps, namely, thermal oxidation and e-beam evaporation for ultra-thin Ti(~ 5 nm)/Au(22 nm)
films, were optimized to result in surface r.m.s roughness ~ 0.2 m and ~ 1.0 nm, after thermal oxidation
and Ti/Au deposition steps respectively. Surface roughness was estimated by atomic force microscope
(AFM) imaging and image analysis. Nano-patterning experiments using thiol based 16-MHA molecular-ink
on fabricated substrates were carried out, under controlled environment conditions, by dip-pen-nanolithography
(DPN) technique. Minimum line-width ~ 60 nm and circular dots radius ~ 175 nm were patterned.

A lower bound on web services composition
A web service is modeled here as a finite state machine. A composition
problem for web services is to decide if a given web service can be constructed
from a given set of web services; where the construction is understood as a
simulation of the specification by a fully asynchronous product of the given
services. We show an EXPTIME-lower bound for this problem, thus matching the
known upper bound. Our result also applies to richer models of web services,
such as the Roman model
Effects of oxytetracycline residues in Thai Koi (Anabas testudineus Bloch) collected from Sylhet, Bangladesh
The present study was conducted to determine the levels of oxytetracycline residues in Thai Koi (Anabas testudineus Bloch) collected from some local fish markets of Sylhet Sadar Upazilla, Bangladesh during March to August, 2016. For the purpose of the study, 24 fresh Thai Koi fish samples were randomly collected from four (4) local markets of Sylhet Sadar Upazilla. Concentration of oxytetracycline residues in collected fish samples were determined by High Performance Liquid Chromatography (HPLC) at the Food Toxicology Laboratory of Institute of Food Science and Technology, Bangladesh Council of Scientific and Industrial Research, Dhaka. The results showed that 9 (37.50%) samples with detectable amount of oxytetracycline residues (mean = 42.30±3.00 ppb) were found in Thai Koi. Oxytetracycline residues level below detection limit was also reported in 15 (62.50%) samples of Thai Koi during this study. The detected residues of oxytetracycline in this fish sample did not exceed the maximum residue limit (MRL) 100 ppb recommended by the European Commission. Though residue level of oxytetracycline is lower than the MRL but long term exposure could be hazardous for human health. For that reason, control of antibiotic usage in aquaculture, regular residue monitoring, legislations and regulations for the use of antimicrobials in aquaculture and food safety education are utmost things in this regard
