Pulling the Past into the Present: Curating Islamic Art in a Changing World, a Perspective from Berlin
Authors: Weber Stefan
Published: May 2018

Demographic and social change presents museums with challenges at various levels. Islam has become a core referent in public discourse, which often also affects views of collective identity and personal political stances in fundamental ways. The dominant place of Islam in global debate does not stop at the doors of our museums. The main thesis of this article is that exhibitions of Islamic art are, whether we like it or not, sites of identity negotiation where relations to ‘me and my world’ are established. This article takes a closer look at the process of identity formation in regard to contemporary museum politics. It asks questions such as, ‘In what ways do the social dynamics surrounding the subject of Islam function, and how do these impact museum spaces?’; ‘What role do museums have in these emerging dynamics?’; and ‘How do curators respond to the shifting needs of visitors?’ The classical layout and communication strategies of Islamic art collections were often insufficiently framed to address these layered concerns, despite curators’ knowledge of the rich diversity of Islamicate histories. During the last few years, however, different curatorial teams have struggled to discover better techniques and narratives for this diversity. The Berlin Museum contains one such team, and the second part of this article outlines some of their new approaches.
A Museum without Walls: Dar al-Athar al-Islamiyyah’s Cultural Diplomacy
Authors: Fabbri Roberto
Published: May 2018

For almost two decades, Gulf sheikhdoms have consolidated their political mandate and legacy through large acquisition programmes of artworks and through building world-class museums. The aim of these policies is to foster a sense of national collective identity internally, while promoting the trustworthy profile of a fully advanced society to the rest of the world. While this seems to be the regional trend, this article investigates the anomaly of Dar al-Athar al-Islamiyyah (DAI), a Kuwaiti cultural institution predating most of the museums in the Gulf. I argue that the DAI offers an alternative narrative that focuses on art as a diplomatic agent to explain Islamic civilization in broad terms, as opposed to being limited to one country’s national discourse. In 1991, as a consequence of the first Gulf War, DAI’s building was burned down. This unusual condition of being a ‘museum without walls’, regrettably protracted for many years, transformed DAI into a fluid entity showcasing the depth of Islamic civilization locally and internationally through its broad collection. DAI’s primary tool of cultural diplomacy was, and still is, its travelling exhibitions. This article explores their museographical aspects, surrounding context, and subsequent reception.
Artist sanction and street works
Authors: Moser Shelby
Published: May 2018

This article analyses some of the relevant features that pertain to graffiti, street art and viewer appreciation. Although street works are normally recognized by their formal features, I will focus on their contextual features, which are of prime import since they guide our responses to the works. Although context might depend on an account of an artist’s intentions, I will instead focus on the artist’s sanction. We can identify sanctions of artists by identifying the constraints and conventions that they work within, which allows us to appeal to the artist’s intent while minimizing the degree of interpretation.
The relationship between test preparation and state test performance: Evidence from the Measure of Effective Teaching (MET) project
Authors: Li Hongli , Xiong Yao
Published: May 2018

The passage of the NCLB Act enhanced accountability policies in the United States, and standardized testing became prevalent as a policy tool to ensure accountability in K-12 education. Given the high stakes of state administered accountability tests, more school teachers have adopted test-preparation strategies to ensure satisfactory student performance on state tests. However, it remains unclear as to whether and how test preparation relates to students’ state test performance. In this study, by drawing on the Measure of Effective Teaching (MET) longitudinal dataset, we examined the relationship between test preparation and students’ state test performance. We found that students with lower test performance in Year 1 received more test preparation in Year 2; however, the effects of test preparation on students’ state test performance were rather small and mixed. In regard to racial differences, we found that Black and Hispanic students received more test preparation than White students. Further, the effect of test preparation measured by the item “practicing for the state test” on state test performance was significantly greater for Black and Hispanic students than for White students. The implications of the study, its limitations, and directions for future research are also discussed.
A research on top managers’ leadership styles’ effect on applying strategic plans in public universities
Authors: Rüzgar Nilüfer
Published: May 2018

According to the Law of Public Fiscal Management and Control, item 5018, all public sector organizations and municipalities have to prepare a strategic plan. However, in all plans and projects, success depends on the attitudes of the leader. This critical success factor constitutes greater importance in public universities. Although the strategic plan designed in the most effective frame; the role of the leader cannot and should not be ignored. In this sense, the leadership style of the leader/manager has an important effect.The purpose of this study is to measure the perception of both academic and administrative personnel, about the strategic planning in their institution and their perception about the role of the leader in the process of strategic planning. In the frame of the research, academic and administrative personnel of state universities in the city of Bursa, Turkey, are taken as population. A survey that consists of demographical questions and two scales, measuring Leadership Styles Perception and Strategic Planning Perception, are applied. The surveys are analyzed by using SPSS 20.0 package program. According to the results, Transformational Leadership Style has an increasing effect on Strategic Productivity. There is also a statistically significant effect of Autocratic and Transformational Leadership Styles on Strategic Effectiveness. On the other hand, there is not a statistically significant relationship between Democratic Leadership and Strategic Effectiveness. While Autocratic Style causes a decrease in Strategic Effectiveness, Transformational Leadership Style has an increasing effect on Strategic Effectiveness. In addition to this, there is a statistically significant effect of Autocratic and Transformational Leadership Styles on Strategic Effectiveness.

Energi celah pita yang lebar dari semikonduktor TiO2 yang setara dengan cahaya ultraviolet (l<380 nm) membatasi aplikasi fotokatalitik hanya terbatas pada daerah ultraviolet dan tidak pada daerah cahaya tampak (l = 400 nm–700 nm). Pada penelitian ini dilakukan sintesis TiO2 teremban nitrogen yang dipreparasi melalui metode sol-gel. Prekursor TiCl4 digunakan sebagai sumber titanium dioksida dan CO(NH2)2 sebagai sumber nitrogen dan divariasi pada jumlah konsentrasi N dengan variasi 20 g, 30 g, 40 g dan 50 g. Refluks dilakukan pada suhu 100oC selama 7 jam dilanjutkan dengan pengeringan selama 3 jam pada suhu 100oC, dan kalsinasi pada suhu 500oC selama 7 jam . Karakterisasi N-doped TiO2 dilakukan menggunakan X-ray Diffraction (XRD), Fourier Transform–Infra Red spectroscopy (FTIR), dan UV- Visible diffuse reflectance spectra (UV-Vis DRS). Berdasarkan data XRD diketahui bahwa kristal N- doped TiO2 berstruktur anatase dengan indeks Miller 101. Spektra FTIR menunjukkan pergeseran serapan vibrasi O-Ti-O pada bilangan gelombang 400-1050 cm-1, diperkirakan sebagai akibat terbentuknya ikatan N-Ti-O.

This work presents the synthesis of PANI-PVA-ZnS nanocomposite films by gamma irradiation approach. The samples were irradiated with different doses ranging from 10 kGy to 40 kGy. Subsequently, structural, morphological, optical and electrical characteristics of the samples were investigated. Fourier transform infrared (FT-IR) spectroscopy was employed to study the chemical structure of the samples. Field emission scanning electron microscopy (FE-SEM) was used to investigate the morphology of nanocomposites. The electronic absorption characteristics of the samples were measured by means of UV-Vis spectroscopy. The AC and DC electrical behaviors of the samples were characterized using LCR meter in the frequency range of 20 Hz to 1 MHz. The impedance values of the samples were extracted from Cole-Cole plots and consequently DC conductivity was calculated.

Authors: Yildiz Esra
Published: May 2018

Zr0.99Gd0.01O2, Zr0.98Gd0.01Dy0.01O2 and Zr0.98Gd0.01Yb0.1O2 phosphors were synthesized by Pechini method at 1200 °C for 12 h in air. The phosphors were characterized by using X-ray powder diffraction (XRD), differential thermal analysis/thermal gravimetry (DTA/TG), scanning electron microscopy (SEM) and photoluminescence spectrofluorometer (PL). X-ray powder diffraction studies showed that the phosphors were crystallized as monoclinic and tetragonal multiphases. The particle size of the phosphors after heat treatment at 1200 °C was found to be of 200 nm to 250 nm. Luminescence studies on these phosphors have been carried out on the emission and excitation, along with lifetime measurements.

Published: May 2018

During the past few years, metasurfaces have been used to demonstrate optical elements and systems with capabilities that surpass those of conventional diffractive optics. Here, we review some of these recent developments, with a focus on dielectric structures for shaping optical wavefronts. We discuss the mechanisms for achieving steep phase gradients with high efficiency, simultaneous polarization and phase control, controlling the chromatic dispersion, and controlling the angular response. Then, we review applications in imaging, conformal optics, tunable devices, and optical systems. We conclude with an outlook on future potentials and challenges that need to be overcome.
Dispersion features of complex waves in a graphene-coated semiconductor nanowire
Authors: Yu Pengchao , Fesenko Volodymyr I. , Tuz Vladimir R.
Published: May 2018

The dispersion features of a graphene-coated semiconductor nanowire operating in the terahertz frequency band are consistently studied in the framework of a special theory of complex waves. Detailed classification of the waveguide modes was carried out based on the analysis of characteristics of the phase and attenuation constants obtained from the complex roots of characteristic equation. With such a treatment, the waves are attributed to the group of either “proper” or “improper” waves, wherein their type is determined as the trapped surface waves, fast and slow leaky waves, and surface plasmons. The dispersion curves of axially symmetric TM0n and TE0n modes, as well as nonsymmetric hybrid EH1n and HE1n modes, were plotted and analyzed in detail, and both radiative regime of leaky waves and guided regime of trapped surface waves are identified. The peculiarities of propagation of the TM modes of surface plasmons were revealed. Two subregions of existence of surface plasmons were found out where they appear as propagating and reactive waves. The cutoff conditions for higher-order TM modes of surface plasmons were correctly determined.

Mixed matrix membranes (MMMs) for ethanol purification through pervaporation: current state of the art
Authors: Castro-Muñoz Roberto , Galiano Francesco , Fíla Vlastimil , Drioli Enrico , Figoli Alberto
Published: May 2018

Over the last few decades, different polymers have been employed as materials in membrane preparation for pervaporation (PV) application, which are currently used in the preparation of mixed matrix membranes (MMMs) for ethanol recovery and ethanol dehydration. The ethanol-water and water-ethanol mixtures are, in fact, the most studied PV systems since the bioethanol production is strongly increasing its demand. The present review focuses on the current state of the art and future trends on ethanol purification by using MMMs in PV. A particular emphasis will, therefore, be placed on the enhancement of specific components transport and selectivity through the incorporation of inorganic materials into polymeric membranes, mentioning key principles on suitable filler selection for a synergistic effect toward such separations. In addition, the following topics will be discussed: (i) the generalities of PV, including the theoretical aspects and its role in separation; (ii) a general overview of the methodologies for the preparation of MMMs; and (iii) the most recent findings based on MMMs for both ethanol recovery and ethanol dehydration for better evolution in the field. From the last decade of literature inputs, the poly(vinyl alcohol) has been the most used polymeric matrix targeting ethanol dehydration, while the zeolites have been the most used embedded materials. Today, the latest developments on MMM preparation declare that the future efforts will be directed to the chemical modification of polymeric materials as well as the incorporation of novel fillers or enhancing the existing ones through chemical modification.
Chemistry and spectroscopy of cross-conjugated and pseudo-cross-conjugated quinolinium-ethynyl-benzoate mesomeric betaines
Authors: Batsyts Sviatoslav , Ramírez Francisco J. , Casado Juan , Namyslo Jan C. , Schmidt Andreas
Published: May 2018

The three isomers 1-methylquinolinium-2-, 3-, and 4-ethynyl(phenyl-4-carboxylates) belong to two distinct types of heterocyclic mesomeric betaines. The quinolinium substituted in position 3 is a cross-conjugated mesomeric betaine (CCMB), whereas the quinolinium derivatives substituted in positions 2 and 4 are members of the class of pseudo-cross-conjugated mesomeric betaines (PCCMBs). While the charges are strictly separated within the common π-electron system of the CCMB according to the canonical formulae, the charges are effectively but not exclusively delocalized in the PCCMBs because cumulenoid resonance forms including electron sextet structures without external octet stabilization can be formed in accordance with the definition of PCCMBs. As a consequence, despite being closely related structures, the three isomers differ in their chemical and spectroscopic behaviors. Thus, on trying to hydrolyze the ester group of the methyl quinolinium-2-ethynyl-benzoate into the corresponding acid by subsequent treatment with sodium hydroxide in methanol and aqueous hydrochloric acid at pH 3, the acetal methyl 1,1-dimethoxy-2-(quinolinium-ylidene)ethyl]benzoate and the corresponding β-enamino carbonyl compound were formed, respectively. The corresponding acids of the 2- and 4-substituted quinolinium-ethynyl-benzoates were obtained by a modified procedure. On deprotonation, the resulting cross-conjugated quinolinium-3-ethynyl-benzoate betaine proved to be stable, whereas the corresponding pseudo-cross-conjugated quinolinium-2- and -4-ethynyl-benzoate betaines decomposed. Frontier orbital profiles were calculated, and IR and Raman spectra of the starting materials were measured and calculated to analyze the differences of CCMBs and PCCMBs of mesomeric betaines possessing triple bonds. A higher contribution of the cumulenoid resonance forms to the overall structure of the PCCMBs was determined.

Authors: Liu Hu-Chen , Zhao Hao , You Xiao-Yue , Zhou Wen-Yong
Published: May 2018

With the development of modern technology, industrial robots have been applied extensively in different industries to perform high-risk jobs and produce high-quality products. However, selecting an appropriate robot for a specific manufacturing environment is a difficult task for decision makers because of the increase in complexity, production demands, and the availability of different robot types. Normally, robot selection can be regarded as a complex multicriteria decision-making problem, and decision makers often use uncertain linguistic terms to express their assessments because of time pressure, lack of data, and their limited expertise. In this article, a modified MULTIMOORA (Multiobjective Optimization by Ratio Analysis plus the Full Multiplicative Form) method based on hesitant fuzzy linguistic term sets (named HFL-MULTIMOORA) is proposed for evaluating and selecting the optimal robot for a given industrial application. This method deals with the decision makers’ uncertain assessments with hesitant fuzzy linguistic variables, which can increase the flexibility of representing linguistic information. Finally, an empirical example is presented to demonstrate the proposed method, and the results indicate that the HFL-MULTIMOORA provides a useful and practical tool for solving robot selection problems within a hesitant linguistic information environment.
Study in the Durability of Silane-Based Mortar
Authors: Liu Jiesheng , Faping Li , Liwei Du , Xiaofan Liu , Rongtang Zhang
Published: May 2018

This article investigates the durability properties of mortar containing three types of silanes as integral additives. Compared with the plain mortar, mortar samples with silanes exhibited better performance when subjected to freezing-thawing cycles and chemical and carbonation corrosion. The addition of silanes also results in the formation of chemical bonding across the interface, which is helpful for improving crack resistance. Additionally, mortar samples with γ-Glycidoxypropyl methyldimethoxysilane (GDMMS) show better freezing-thawing resistance and chemical corrosion resistance than do mortar samples with γ-aminopropytriethoxysilane and 3-(Trimethoxysilyl)propyl methacrylate, because of the more effective interface between the GDMMS and mortar. For mortar samples with silanes, the effect of the types and quantity of silanes on the crack resistance of mortar and carbonation corrosion is not obvious. Scanning electron microscopy images show that silanes perform the networking and “coupling” effect to hold mortar particles, resulting in the improvement of mortar durability.

Fishing rights, property rights, human rights: the problem of legal lock-in in UK fisheries
Authors: Appleby Thomas , Cardwell Emma , Pettipher Jim
Published: May 2018

Property rights are a widely advocated policy tool to encourage stewardship over a range of environmental goods. Despite the extent to which property rights are dependent upon law to work, economists rarely consider that property rights are enmeshed within a complex web of pre-existing national and international legal frameworks—such as human rights law—that put strict limitations on the way they operate. This important issue is illustrated here with reference to the legal struggles in the UK around the “ownership” of fishing rights. The social and economic changes under market-based management in the UK made the fisheries regulatory regime unpopular, and undoubtedly contributed to the overwhelming vote within the catch sector to leave the European Union, even though the responsibility to allocate fishing opportunities to the British fishing industry lay with the UK authorities. The lesson from the UK experience is that despite the legal-blindness of much resource economics, the application of economic theory should not outrun its legal foundations. We conclude that promoting the allocation of public fishing rights to the private sector without adequate safeguards—such as a valuation of the rights in question and carefully considered written terms and conditions—could be considered negligent.
Investigating Machinability in Hard Turning of AISI 52100 Bearing Steel Through Performance Measurement: QR, ANN and GRA Study

Published: May 2018

The existing endeavor investigates on machinability characteristics through performance measurement of flank wear, surface quality and chip morphology during finish turning of AISI 52100 bearing steel (55 ± 1 HRC) under dry environment employing carbide insertcoated along with various layers (TiN/TiCN/Al2O3). Secondly the influence of machining variables viz. cutting speed, feed rate and depth of cut on responses are assessed by ANOVA and modeled through quadratic regression and artificial neural network. Multiparametric optimization of cutting conditions has been obtained through Taguchi based grey relational analysis. Finally, tool life at ideal conditions has been evaluated through experiment. Based on the study, it is disclosed that coated carbide with multilayer insert outperformed during hard machining as wear at the flank surface and surface quality are within the benchmark cap of 0.3 mm and 1.6 microns respectively. From the chip morphology analysis, multilayer coated carbide insert generates lower temperature and maintains cutting edge sharpness and delays the growth of tool wear. ANN model using multilayered feed forward network yields accurate prediction of responses with minimum error percentage compared to QR model. The optimal parametric combination through GRA approach is found to be d1 (0.1 mm)-f1 (0.04 mm/rev)-v2 (110 m/min) and is greatly improved. Feed is the compelling aspect for multi-responses pursued by cutting speed. The tool life at optimized cutting condition is found to be approximately 19minutes.
Identifying Genetic Players in Cell Sheet Morphogenesis Using a Drosophila Deficiency Screen for Genes on Chromosome 2R Involved in Dorsal Closure

Published: May 2018

Cell sheet morphogenesis characterizes key developmental transitions and homeostasis, in vertebrates and throughout phylogeny, including gastrulation, neural tube formation and wound healing. Dorsal closure, a process during Drosophila embryogenesis, has emerged as a model for cell sheet morphogenesis. ∼140 genes are currently known to affect dorsal closure and new genes are identified each year. Many of these genes were identified in screens that resulted in arrested development. Dorsal closure is remarkably robust and many questions regarding the molecular mechanisms involved in this complex biological process remain. Thus, it is important to identify all genes that contribute to the kinematics and dynamics of closure. Here, we used a set of large deletions (deficiencies), which collectively remove 98.5% of the genes on the right arm of Drosophila melanogaster’s 2nd chromosome to identify “dorsal closure deficiencies”. Through two crosses, we unambiguously identified embryos homozygous for each deficiency and time-lapse imaged them for the duration of closure. Images were analyzed for defects in cell shapes and tissue movements. Embryos homozygous for 47 deficiencies have notable, diverse defects in closure, demonstrating that a number of discrete processes comprise closure and are susceptible to mutational disruption. Further analysis of these deficiencies will lead to the identification of at least 30 novel “dorsal closure genes”. We expect that many of these novel genes will identify links to pathways and structures already known to coordinate various aspects of closure. We also expect to identify new processes and pathways that contribute to closure.

RESUMO A demanda de petróleo e derivados provoca acidentes que contaminam extensas áreas. A maioria dos trabalhos sobre os efeitos dessa contaminação refere-se à germinação e desenvolvimento vegetal, pouco se sabendo sobre os efeitos na estrutura de tecidos e células. Este trabalho teve como objetivo analisar o efeito do solo contaminado por petróleo e solo biorremediado na anatomia de plântulas de Mimosa pilulifera (Leguminosae). O experimento foi realizado com solo da REPAR/PETROBRÁS, Araucária-PR, onde ocorreu um vazamento de petróleo em 2000. O experimento constou de três tratamentos: solo contaminado com petróleo, solo biorremediado e solo não contaminado, com cinco repetições. Após 30 dias da semeadura, foram analisados anatomicamente a raiz, hipocótilo, cotilédone e eofilo e realizados testes microquímicos com sudan III, lugol e cloreto férrico. Mensuraram-se: diâmetro do cilindro vascular e espessura do córtex da raiz, diâmetro do hipocótilo e espessura dos cotilédones e eofilos. A estrutura celular radicial de M. pilulifera sofreu maior interferência no solo contaminado que no biorremediado. Na parte aérea, a única alteração foi a redução da espessura do eofilo em solo contaminado.

RESUMO (Palinotaxonomia de espécies do gênero Acacia (Leguminosae-Mimosoideae) no semi-árido brasileiro) Foi realizado o estudo palinológico de 12 espécies de Acacia: A. farnesiana (Acacia subg. Acacia) e A. bahiensis, A. globosa, A. kallunkiae, A. langsdorffii, A. martiusiana, A. monacantha, A. piauhiensis, A. polyphylla, A. riparia, A. tenuifolia e A. velutina (Acacia subg. Aculeiferum). Os grãos de pólen foram acetolisados, medidos, descritos e ilustrados sob microscópio de luz e eletrônico de varredura. Os grãos de pólen em Acacia são reunidos em políades calimadas, médias ou grandes, de contorno esferoidal, em vista frontal e elíptico, em vista lateral, com 16 grãos de pólen, organizados de forma regular, com oito grãos de pólen em cada face, 4-porados. Em A. farnesiana, são observados 24-32 grãos de pólen organizados de forma irregular, 3-sulcados. Os grãos de pólen da políade são pequenos, subquadrados na face distal e piramidal, quando em vista equatorial. A sexina é granulada ou rugulada, na maioria das espécies. Conclui-se que as espécies não podem ser separadas através das suas características palinológicas, com exceção de A. farnesiana.

Background Interstitial fibrosis is associated with chronic renal failure. In addition to fibroblasts, bone marrow–derived cells and tubular epithelial cells have the capacity to produce collagen. However, the amount of collagen produced by each of these cell types and the relevance of fibrosis to renal function are unclear.

Methods We generated conditional cell type–specific collagen I knockout mice and used (reversible) unilateral ureteral obstruction and adenine-induced nephropathy to study renal fibrosis and function.

Results In these mouse models, hematopoietic, bone marrow–derived cells contributed to 38%–50% of the overall deposition of collagen I in the kidney. The influence of fibrosis on renal function was dependent on the type of damage. In unilateral ureteral obstruction, collagen production by resident fibroblasts was essential to preserve renal function, whereas in the chronic model of adenine-induced nephropathy, collagen production was detrimental to renal function.

Conclusions Our data show that hematopoietic cells are a major source of collagen and that antifibrotic therapies need to be carefully considered depending on the type of disease and the underlying cause of fibrosis.

In this note we find that after a given monetary policy surprise, primary dealers--key intermediaries in interest rate markets--tend to adjust their positions in the U.S. Treasury market and their exposures to interest rates more when the prevailing level of policy uncertainty is low than when it is high.

Published: May 2018

The paper focuses on the problem of accessibility and quality of higher education for students with disabilities. We describe our experience in organising network interaction between the MSUPE Resource and Training Center for Disabled People established in 2016-2017 and partner universities in ‘fixed territories’. The need for cooperation and network interaction arises from the high demand for the cooperation of efforts of leading experts, researchers, methodologists and instructors necessary for improving the quality and accessibility of higher education for persons with disabilities. The Resource and Training Center offers counseling for the partner universities, arranges advanced training for those responsible for teaching of the disabled, and offers specialized equipment for temporary use. In this article, we emphasize the importance of organizing network interactions with universities and social partners in order to ensure accessibility of higher education for students with disabilities.

Background: Tongue squamous cell carcinoma (TSCC) is one of the aggressive forms of oral cancer with a high recurrence rate. Forty percentages of all TSCC patients have neck metastasis at the time of diagnosis. The status of cervical lymph nodes at presentation is the single most important prognostic factor in TSCC. This study was focused on establishing relation between the tumor depth and neck node metastasis in carcinoma of tongue. Authors accessed the patterns of cervical node metastasis in it.Methods: prospective non-randomised study of 100 patients was carried out. After detail clinical history punch biopsy were taken from the tongue lesion. Biopsy proven cases of early squamous cell carcinoma (T1/T2) with clinically negative neck (cN0) were included in this study. Ultra-sonography of the tongue using 7.5 MHz probe was performed in all cases to know the depth of lesion. Final histopathological findings i.e. pT, pN, differentiation and depth of invasion were compared with pre-operative clinical and radiological findings.Results: Out of 100 patients, 62 were males and 38 were females. Clinically 56 patients were belonged to T2. Ultra-sonography of tumor had high sensitivity and specificity. Node positivity increased with the depth of primary tumor. On histopathological examination, positive node observed in total 25 patients. Number of occult neck node positivity raised with increased size of primary tumor. i.e. 15% and 31% with pT1 and pT2, respectively. Level II was the most common site for cervical node involvement followed by level III.Conclusions: Ultra-sonography was a reliable tool to access the depth of tumor pre-operatively in the cases of tongue carcinoma patients with sensitivity and specificity more than 90%. Node positivity increased with the depth of primary tumor. Tumor thickness is a significant predictor of nodal metastasis and elective neck dissection should be decided accordingly.

Background: Hypertension is one of the most common diseases worldwide. Early diagnosis of Hypertension is an important strategy in its control. The purpose of this study was to determine the prevalence of hypertension and risk factors among school going children and to find its relationship with regard to age, sex, height, weight and BMI criteria and comparing the values with available standards.Methods: It is a prospective cross-sectional study done in the age group of 10 to 16 years. Children were selected from urban and rural areas in and around Mysore city. Blood pressure measurements were taken by mercury Sphygmomanometer as per recommendation of American Heart Association. Three readings of blood pressure were recorded for each subject and were correlated with age, gender and anthropometry. All the statistical operations were done through SPSS.Results: The present study was conducted amongst children in the age group of 10-16 years in rural and urban schools. A total of 2000 children were included in the study. BP measurements of 1000 subjects in three urban school children and 1000 school children in one rural school children in Mysuru district were done. In rural school children prevalence of systolic hypertension was 2.8% in males and 0.9% in females. In urban school children prevalence of systolic hypertension was 2.1% in males and 1.2% in females.Conclusions: Blood pressure measurement in children is pivotal in clinical examination. Periodic measurement of blood pressure would identify hypertension at an early age. Further studies are needed to know the exact prevalence of hypertension and long term follow up studies are required to know the effect and risk factors associated in children with sustained hypertension.
