Biofilms were obtained from cocoons of the silkworm, Bombyx mori, involving removal sericin, extraction and solubilization fibroin fibers, dialysis dispersions preparation biofilms by casting process. Biofilm transparency was verified UV?Vis spectroscopy thermal stability thermogravimetric/differential scanning calorimetry (TG/DSC). Soon after preparation, solidification solution prepared extra...

Simulium (Nevermannia) khunklangense sp. nov. is described from females, males, pupae and larvae collected in Doi Inthanon National Park, Chiang Mai, Thailand. This new species is placed in the vernum species-group of the subgenus Nevermannia and is similar to S. (N.) chomthongense Takaoka & Srisuka described from Doi Inthanon National Park, Thailand, but is distinguished in the male by the num...

INTRODUCTION Abdominal cocoon syndrome is characterized by small bowel encapsulation by a fibro-collagenous membrane or "cocoon". It is a rare cause of intestinal obstruction. PRESENTATION OF CASE A 42-year old man presented with sub-acute intestinal obstruction. Intra-operatively, the entire small bowel was found to be encapsulated in a dense fibrous sac. The peritoneal sac was excised, foll...

The tropical tasar silkworm, Antheraea mylitta, is a semi-domesticated vanya silk-producing insect of high economic importance. To date, no molecular marker associated with cocoon and shell weights has been identified in this species. In this report, we identified a randomly amplified polymorphic DNA (RAPD) marker and examined its inheritance, and also developed a stable diagnostic sequence-cha...

this thesis attempts to investigate the effects of prelistening activities on enhancing iranian efl learners` listening comprehension. the present study investigated ways in which learners` background knowledge could be activated in order to enhance their l2 listening comprehension by limiting the number of possible text interpretations prior to listening. the experiments conducted in this study examined the effect of prior knowledge and vocabulary teaching on iranian efl learners listening comprehension. the current study has two purposes: one is to investigate the effect of background knowledge on the second language listening comprehension of iranian intermediates and the other is to determine whether second language is facilitated by the introduction of unknown vocabularies in the form of prelistening activities. to conduct the study different instruments such as listening proficiency test and four listening tests such as pre and posttests were used and various statistical processes and techniques including paired-sample t-test, and analysis of variance (anova) were used. the findings of this study supported all three hypotheses tested. differences were found between the means of preteaching vocabulary variable, the background knowledge activation variable, and mean difference between these two strategies variable. subjects scored higher when the unknown words were taught in advance. likewise, subjects scored higher when they were asked some relevant questions about the topic than on those without them. there was, in addition, a significant difference between the means of preteaching vocabulary strategy and background knowledge activation strategy. in fact, preteaching vocabulary had a better effect in enhancing the students’ listening comprehension, in comparison to background knowledge activation strategy.

Cosmic rays with energies up to a few PeV are known be accelerated within the Milky Way. Traditionally, it has been presumed that supernova remnants were main source of very-high-energy cosmic but theoretically is difficult get protons and observationally there simply no evidence support as sources hadrons above tens TeV. One possible those Galactic Center region. Here we report observations 1-...

Long gamma ray bursts (LGRBs) are associated to the collapse of a massive star and formation relativistic jet. As jet propagates through star, it forms an extended, hot cocoon. The dynamical evolution jet/cocoon system its interaction with environment has been studied extensively both analytically numerically. On other hand, role played by supernova (SN) explosion LGRBs in determining outcome b...

The co-inoculation of mulberry with phosphate solubilizing micro-organisms, nitrogen fixing bacteria and arbuscular mycorrhiza has influenced its macronutrient uptake through leaf. The data revealed that maximum nitrogen (484.12 kg /ha) , phosphorus (59.83 kg /ha) and potassium (244.61 kg/ha) uptake through leaf has taken place due to co-inoculation treatments as compared to the un inoculated t...
