High Circular Dichroism through Planar Plasmonic Metasurfaces and Enhancement through Surface Plasmon Resonances

Research on metasurfaces featuring high circular dichroism has been very active in the last decade, because of possible applications in various fields, such as spintronics, polarization optics and stereochemistry. Despite literature displaying various proposed geometries and methods, today it is hard to define an alternative choice combining high Circular Dichroism (CD), easy realization and robustness of performance. In this work, we show the design approach and first experimental demonstration of a planar plasmonic metamaterial based on a comma-shaped geometry, which can be used to obtain high CD. Our metasurface combines intrinsic chirality and enhancement effects due to high field localization. In particular, the relative correspondence between numerical analyses and experiments shows the possibility to tune the effects of Surface Plasmon Resonances to a certain extent. This is equivalent to the possibility of engineering stable peak values on specific wavelength ranges, even in the presence of geometrical non-idealities due to fabrication. Samples were built through standard top-down fabrication procedures, helped by the symmetry of the extrusion. The ease in implementation, combined with reliable performances, make our proposed metamaterial eligible for adoption for further research in high precision spectroscopy and optical manipulation at industrial scale. Keywords-Circular Dichroism; Metamaterials; Plasmonics; Surface Plasmons; Microfabrication.
Different Backgrounds and English Learning Styles of Bangkok University Student

The purpose of this research was to investigate the influence demographics, gender, faculty, and level of general English has on students’ learning styles. Subjects were 410 students representing Accounting, Business Administration, and Economics faculties and studying Business English courses at Bangkok University. A Perceptual Learning Style Preference Questionnaire: PLSPQ (Reid, 1987) was used for collecting data via a five point Likert scale. Data were analyzed and calculated in percentage, mean, standard deviation and Chi-squared test at the level of 0.05. The results show that Bangkok University students do not have a specific style of learning English. The three main forms of learning English are; study in a group, learning and practicing in different situations, and listening respectively. Some results varied based on gender, faculty and levels of academic performance in general English variables. However, the styles of learning English did not.
FUNCTIONAL EVALUATION OF GAIT IN WISTAR RATS AFTER DEMYELINIZATION WITH ETHIDIUM BROMIDE IN SUPPLEMENTATION OF VITAMIN D

: Introduction : In the world, the glycotoxic model has been used through the use of ethidium bromide (BE) which involves demyelination with the process of remyelination in the central nervous system (CNS). This experimental method helps to detail the events involved in responding to the finding of remyelination in diseases such as Multiple Sclerosis . Objective : This study aims to assess whether Vitamin D has the potential to alter the gait movement of demyelinated rats with ethidium bromide (BE) through experimental glycotoxic models with the use of ethidium bromide (BE) in order to conjugate knowledge about nerve regeneration and the development of strategies that promote the recovery of nervous tissue. Results : The treatment group with 100.000 IU/week demonstrated a significant difference in gait on hind legs compared to the positive control group in specificities in CPMO and APMA. Conclusion : It was possible to concluded in this study that the treatment with Vitamin D supplementation in rats with lesions in the central nervous system showed a faster functional performance and with a greater grip evidenced in gait in high doses of Vitamin D supplementation, in this case, equivalent to 50.000 IU/week to 100.000 IU/week.

Discrimination of the Fundamental Frequency by Children: A comparison of two alternative procedures

This study investigated the fundamental frequency (F0) discrimination of complex tones by children under two decision paradigms. Children aged 4, 5, 6, 10 and young adults participated in the study. In the 2-interval, 2-alternative forced-choice (2I-2A FC) decision paradigm, participants were asked to decide whether the two pairs of tones were the same or different. In the 3-interval, 2-alternative forced-choice (3I-2A FC) decision paradigm, they were required to identify the tone in the second or third interval that was identical to the first tone. The F0 discrimination ability was examined with reference to a standard tone with 120Hz F0. The results showed that children’s F0 discrimination under both decision paradigms reached adult level by 10 years of age. The results also indicated that the F0 discrimination thresholds found in the 2I-2A FC decision paradigm were significant smaller than those found in the 3I-2A FC decision paradigm. No interaction effect was observed between the effect of age and task-related demand on memory. The findings give implication for the choice of decision-making paradigm in further investigation on the perception studies in normally developing children and the working memory studies in children with disordered development.
University of Birmingham Methylation changes in the TFAP2E promoter region are associated with BRAF mutation and poorer overall & disease free survival in colorectal cancer

Introduction: BRAF mutant colorectal cancer carries a poor prognosis which is thought to be related to poor response to conventional chemotherapy. BRAF mutation is associated with the serrated tumour phenotype. We hypothesised that one of the mechanisms by which BRAF mutant colorectal cancer demonstrate poor outcomes with chemotherapy is abnormal gene methylation Methods: The Cancer Genome Atlas (TCGA) methylation data was analysed using a linear regression model with BRAF mutation as an independent variable. Expression datasets were also obtained to correlate functional changes. Top differentially methylated probes were taken forward for validation by methylation pyrosequencing. These probes were analysed on a cohort of patients enriched for BRAF mutations taken from the VICTOR and QUASAR2 studies. Results: In an analysis of 91 tumours (9 BRAF mutant, 82 wild type), the Illumina probe cg11835197 was the probe identified as top differentially methylated (p = 2.56x10-7, Bayes Factor (BF) =6.54). This probe covered a region -413bp from the promoter region of TFAP2E. We found a complex pattern of CpG specific methylation of this region which was associated with both overall (p=0.044) and disease free (p=0.046) survival. Discussion: BRAF mutant tumours may attain part of their chemoresistance from abnormal TFAP2E methylation, which has not previously been described.
Nondispersive Infrared Ray CH4 Gas Sensor Using Focused Infrared Beam Structures

We propose a concave optical cavity structure for use in a high-performance nondispersive infrared ray (NDIR) methane gas sensor module. By using a concave mirror structure, the maximum output voltage and voltage difference between 0 and 9,500 ppm increased by more than 160% compared with using a vertical mirror structure. The output voltage dependence of the thermopile location was tested in the case of a concave mirror structure. The output voltage increased from 2.75 to 3.63 V with the thermopile detector placed at distances of 2 and 3 mm from the reference position. It was found that the output voltage of the sensor decreased by more than 45% from 2.16 to 1.18 V after three years of operation in the case of the vertical mirror structure.
A clinical study on bovine dermatophilosis and its public health importance

Dermatophilus congolensis is a bacterium that causes exudative dermatitis with scab formation in bovines and is characterized by typical focal (or) localized lesions with “paintbrush” aspect and occasionally as disseminated cutaneous disease. Humidity and ticks like Amblyomma variegatum are the predisposing factors. As this organism also affects human beings, Dermatophilosis is considered as zoonotic disease with public health importance. This study describes skin lesions in 30 bovines from a herd of grazing livestock in Pagadapally village, Jagtial district, Telangana state, India. Lesions were noticed all over the body especially at the dorsum, neck and shoulders consisting thick grayish to dark brown scabs with exudates and blood. Blood samples were collected from all affected animals. Impression smears were prepared from 10 animals with typical lesions taken from the base of the freshly removed scabs along with the collection of crusts, exudates and pustules under proper aseptic precaution. The smears were stained with Giemsa stain and samples were processed for isolation and its colonial morphology and growth characteristics were examined on blood agar. The microbiological diagnosis enabled the identification of Dermatophilus congolensis. Among affected 30 animals were considered for the study and randomly divided into three different groups as group 1, 2 and 3 and three different antibiotic therapeutic regimens were given. In terms of recovery rate and preventing death, Gentamicin was found to be the most effective antibiotic, followed by Amoxirum forte and finally Enrofloxacin. However, all group animals were treated with Meloxicam injection and topical scrubbing of the lesions with equal mixture of sodium bicarbonate and sodium chloride and topical spray of Povidone iodine solution. Treatment was not only effective in early, mild cases but also useful among moderately and heavily affected cattle.
Video Notation (ViNo): A Formalism for Describing and Evaluating Non-sequential Multimedia Access

—The contributions of this paper are threefold: (1) the extensive introduction of a formal Video Notation (ViNo) that allows for describing different multimedia transport techniques for specifying required QoS; (2) the application of this formal notation to analyzing different transport mechanisms without the need of detailed simulations; (3) further application of ViNo to caching techniques, leading to the introduction of two cache admission policies and one replacement policy supporting non-sequential multimedia access. The applicability of ViNo is shown by example and by analysis of an existing CDN simulation. We ﬁnd that a pure LRU replacement yields signiﬁcantly lower hit rates than our suggested popularity-based replacement. The evaluation of caches was done by simulation and by usage of ViNo.
Diurnal and Seasonal Variation of Isoprene Biosynthesis-Related Genes in Grey Poplar Leaves

Transcript levels of mRNA from 1-deoxy-D-xylulose 5-phosphate reductoisomerase (PcDXR), isoprene synthase (PcISPS), and phytoene synthase (PcPSY) showed strong seasonal variations in leaves of Grey poplar (Populus 3 canescens [Aiton] Sm.). These changes were dependent on the developmental stage and were strongly correlated to temperature and light. The expression rates of the genes PcDXR and PcISPS were found to be significantly correlated to each other, whereas the expression of the PcPSY gene showed a different seasonal pattern. Protein concentration and enzyme activity of PcISPS showed distinct seasonal patterns peaking in late summer, whereas highest transcription levels of PcISPS were observed in early summer. Moreover, correlation between PcISPS protein concentration and enzyme activity changed, in particular in autumn, when PcISPS protein levels remained high while enzyme activity declined, indicating posttranslational modifications of the enzyme. The positive correlation between dimethylallyl diphosphate levels and PcISPS protein content was found to be consistent with the demonstrated synchronized regulation of PcDXR and PcISPS, suggesting that metabolic flux through the 1-deoxy-D-xylulose 5-phosphate pathway and isoprene emission capacity are closely intercoordinated. Transcript levels ofPcISPS showed strong diurnal variation with maximal values before midday in contrast toPcDXR, whose gene expression exhibited no clear intraday changes. During the course of a day, in vitro PcISPS activities did not change, whereas leaf dimethylallyl diphosphate levels and isoprene emission showed strong diurnal variations depending on actual temperature and light profiles on the respective day. These results illustrate that the regulation of isoprene biosynthesis in Grey poplar leaves seems to happen on transcriptional, posttranslational, and metabolic levels and is highly variable with respect to seasonal and diurnal changes in relation to temperature and light.
Flashing lights at road tunnel emergency exit portals: A Virtual Reality study with low-cost Head Mounted Displays

Previous studies have provided detailed recommendations regarding the design of flashing lights at emergency exit portals in road tunnels. Theory of Affordances have assisted safety designers fixing characteristics such as color, flashing rate, type and number of lights in emergency systems. A systematic evaluation through experiments has, additionally, provide stronger support to define these characteristics. The present project replicates the Virtual Reality (VR) experiment on the design of flashing lights from Ronchi and Nilsson (2015) conducted in a Cave Automatic Virtual Environment (CAVE) with the usage of low-cost VR equipment in order to create a cross comparison between VR technologies and provide stronger support to VR as a research method in several fields of application. The main motivation to perform this comparison arises from premises such as technological advances and accessibility that Head Mounted Displays (HMD) offer nowadays. A HMD powered by a mobile device was, therefore, tested with the purpose of defining if it is a system immerse enough to provide the results offered by more robust technologies. After facing changes and limitations regarding image performance, the results obtained in the cross comparison, which show a high level of similarity (93.33%), justify the usage of low-cost HMD as a research tool in Human Behavior in Fire. Additional justification is reached since the results were also found to be cost-effective and easily obtained.

ROLE OF VCI –OMNIVEIW (4D ULTRASOUND TECHNOLOGY) IN ACCURATE AND FAST DETECTION OF IUCD COMPLICATIONS

Background and purposes: During 2D ultrasound exam of the pelvis we can suspect or partially detect abnormal position of the IUCD but we need a fast ,easy and an accurate technique to accurately diagnose such IUCD complications to deal with it, particularly if the exam was done without specific complain (the most of our patients are referred from the ER department, the most of the referred ER pateints have no symptoms related to IUCD) ,the 3D sonography has two disadvantages , the first one is that the exam is time consuming (time to acquiring a volume of uterus and relatively long time for reconstructing the images through the multiplanar technique, allows visualization of the appropriate sagittal and coronal views),the second disadvantage is that the exam need the operator to be skilled in 3D orientation and subsequent retrieval of the diagnostic planes from acquired volumes. The aim of this work was to demonstrate the significant role of the VCI omniview 4D application in an accurate and fast detection of IUCD complications and to decrease the requirement of skills from the operator as in the 3D sonography where the operator needs to choose the diagnostic planes from the acquired volume (i.e. omniview VCI technique is a fast and simple technique as compared to the 3D sonography with the same accuracy) Methods: This observational comparative study was done at Al Salam International Hospital and Al Azhar University Hospitals between June 2013 to December 2016. 74 patients are diagnosed or suspected to have IUCD abnormalities by 2D ultrasound irrespective to their complain, they underwent complementary transabdominal or transvaginal 3D and 4D (3D volume acquisition of the uterus and Omniveiw VCI 3 and 4D technique). Results: In our study, 4 patients are diagnosed by 2D sonography with no more findings was detected by 3D and 4D sonography however the 3D or 4D omniview VCI sonography is important to confirm the diagnosis and to exclude the presence of other findings, the remaining 70 patients are partially diagnosed or not diagnosed by 2D sonography and accurately diagnosed by other modalities , the same accuracy was obtained by the 3D sonography and the 4D omniveiw VCI sonography however the diagnosis by 3D sonography needs more time , more effort and more operator skills. Conclusion and Recommendations: The VCI omniview 4D sonography is practically better than the 3D sonography in detection of IUCD complications inspite of the same accuracy of both techniques due to the VCI omniview 4D sonography takes less time and less efforts for detection of the findings and also need less operator skills as compared to the 3D sonography.

Conclusion: In summary, LAC-SFN/CCM-NPs was proved to be a promising system for targeted HCC therapy.
Reflections on a Novel Coach Education Program: A Narrative Analysis

This study examines the implementation of Triathlon Canada's novel coach education program within the competition-development context from the perspective of the program designer; the High Performance Director (HPD). An interpretive approach was utilized to create a series of narratives to examine the background, perspectives and approaches used to construct the coach education program. Findings include the unique educational and practical background of the HPD and how it influenced him to design the coach education program the way he did. We also highlight a series of unique innovations for the Triathlon coaches entering the program including, a) submitting a portfolio of prior experiences, b) deemphasizing evaluation and certification and c) the HPD's experiences of getting others to ‘buy’ into the program. We also discuss the various instances of resistance encountered with implementing this type of program and contrast it with other types of conceptualizations of how coaches' learn.
EFFECT OF INDOLE BUTYRIC ACID ON GROWTH OF Bambusa vulgaris Schrad. ex J. C. Wendl. STEM CUTTINGS

A study was carried out to examine the response of Bambusa vulgaris stem cuttings to different concentrations of Indole butyric acid (IB A). Two node cuttings of Bambusa vulgaris of similar sizes were obtained from mother plants u sing secateur and treated with IBA at concentration levels of 50 mol. , 100 mol. , 150 mol. , and 0 mol. ,as control. They were planted direct in plastic pots containing sterilized river sand and laid out in completely randomized block design and replicated three times in a propag ator. The parameters studied were number of leaves per plant, leaf area, culm diameter, biom ass and carbon stock, which were assessed weekly for a period of 12 weeks. The data were subj ected to analysis of variance (ANOVA) and means were separated using the least significan t difference (LSD) at 5% probability level. Significant differences (P<0.05) were observed for all the parameters studied. Stem cuttings with 150 mol. of Indole butyric acid produced the h ighest number of leaves (9 leaves), largest leaf area of 18.20 cm and culm diameter of 1.90 cm and highest carbon sto ck of 14.29 g. Stem cuttings with 100 mol. of Indole butyric acid had l argest biomas while, those without Indole butyric acid had the lowest performance for all the c aracters studied.
Renal Anastomosing Hemangiomas With a Diverse Morphologic Spectrum

Benign vascular lesions have a diverse appearance and can be extremely difficult to classify. We present renal anastomosing hemangiomas from 2 patients that exemplify the potential diverse range of appearances that can occur in this recently described, rare variant of capillary hemangioma. The lesion from one patient was an intravenous hemangioma with closely packed, fenestrated vascular channels that were reminiscent of the splenic red pulp. Also, the endothelial cells contained hyaline globules. On the other hand, the second patient had multifocal tumor. The lesions showed more extensive hyalinization and vascular ectasia reminiscent of cavernous hemangioma. Extramedullary hematopoiesis was a feature in all the tumors, particularly in the second patient where numerous immature blasts were present within vascular spaces.
