Interaction of Hydrogen with a Cobalt(0001) Surface
Authors: Huesges Zita , Christmann Klaus 
Published: March 2013

Abstract
The interaction of hydrogen and deuterium with the Co(0001) surface has been studied in UHV between 90 and 500 K by means of LEED, temperature-programmed thermal desorption (TPD) and work function change (ΔΦ) measurements. Hydrogen adsorbs spontaneously and dissociatively in two atomic binding states denoted as β
1 and β
2 with a high initial sticking probability. The adsorption energies E(β
1) and E(β
2) are 80 and 100 kJ/mol, respectively, if a first-order desorption kinetics is assumed (a second-order kinetic analysis yields unreasonably low values for both the desorption energies and frequency factors). At sufficiently low temperatures, the adsorbed H atoms form a faint (2 × 2) LEED superstructure, which is best developed after an exposure of ∼20 L. From the temperature dependence of the fractional-order beam intensity at different exposures we determine the critical temperature of the (2 × 2) phase as ∼ 243 ( ± 10) K. Similar to the H-on-Ni(111) system the existence range of the (2 × 2) phase in the temperature–coverage plane is asymmetric; i.e., below the critical coverage Θ
crit the respective long-range order has a higher range of stability than above Θ
crit. By analogy with H/Ni(111), we assume a similar honeycomb H structure also for the H-on-Co(0001) system and suggest the critical coverage Θ
crit to be 0.5, i.e., half a monolayer of H atoms. The H-induced work function change is surprisingly small; it decreases, forms a shallow minimum of −18 meV after ∼20 L exposure around the optimum coverage of the (2 × 2) phase and reaches a saturation value of −10 meV. Our data are discussed and compared with previous work on H/Co(0001) and other close-packed transition metal surfaces, especially with the H-on-Ni(111) system.
Isocrates on paradoxical discourse
Authors: Blank Thomas G. M. 
Published: March 2013

It has long been stated that, in Isocrates' Helen, there seems to be an open contradiction between the author's harsh criticism of logoi paradoxoi and the simple fact that his own encomia of Helen and Busiris appear to be specimens of that very genre. Traditionally, this contradiction has been explained by Isocrates' need to distanciate his own work from that of his predecessors.
This paper undertakes a different approach. Isocrates' criticism of paradoxographic literature is based upon observations about what is and what is not allowed in moral epideictic discourse. Isocrates' specific instructions about proper and improper moral argumentation can function as hermeneutical tool to analyze Helen and Busiris. Only in Helen does he observe the rules of argumentation formulated in that very discourse. In Busiris, however, Isocrates adopts the typical modes of argumentation in paradoxographic literature as represented in the works of Gorgias or Polycrates. In consequence, his arguments in Busiris prove to be unconvincing when measured by his own standards formulated in the proemium of both Helen and Busiris. Consequently, the discourse ends in an apology of these arguments which is, once again, defective. In his corresponding discourses Helen and Busiris, Isocrates implictly demonstrates the moral and technical defects inherent in paradoxical discourse. He explicitly reflects these defects in the proemia and epilogues of both speeches. Helen and Busiris should, therefore, be understood as Isocrates' manifesto for moral discourse as opposed to paradoxographic showpieces.

ABSTRACTGarnet-type electrolytes are currently receiving much attention for applications in Li-ion batteries, as they possess high ionic conductivity and chemical stability. Doping the garnet structure has proved to be a good way to improve the Li ion conductivity and stability. The present study includes effects of Y- doping in Li5La3Nb2O12 on Li ion conductivity and stability of “Li5+2xLa3Nb2-xYxO12” (0.05 ≤ x ≤ 0.75) under various environments, as well as chemical stability studies of Li5+xBaxLa3-xM2O12 (M = Nb, Ta) in water. “Li6.5La3Nb1.25Y0.75O12” showed a very high ionic conductivity of 2.7 х 10−4 Scm−1 at 25 °C, which is comparable to the highest value reported for garnet-type compounds, e.g., Li7La3Zr2O12. The selected members show very good stability against high temperatures, water, Li battery cathode Li2CoMn3O8 and carbon. The Li5+xBaxLa3-xNb2O12 garnets have shown to readily undergo an ion-exchange (proton) reaction under water treatment at room temperature; however, the Ta-based garnet appears to exhibit considerably higher stability under the same conditions.

Published: March 2013

ABSTRACTMolybdenum disulfide (MoS2) nanostructures with three different morphologies are synthesized and tested with respect to their applicability in lithium ion batteries. Thereby, electrolytes based on ionic liquids are used. The electrochemical performance of nanostructures and thin films is compared to evaluate the influence of the morphology. Characterization methods include X-Ray diffraction (XRD), cyclic voltammetry (CV), galvanostatic cycling and thin film calorimetry. The thin film and the nanostructured samples show a reversible capacity of 525 mAh/g and a maximum capacity 225 mAh/g, respectively.
Volcanic hydro-geomorphology of the Montagne Pelée and the rediscovery of an ancestral problematic (Carib, Kalinago) in the Lesser Antilles
Authors: Lalubie Guillaume 
Published: March 2013

AbstractThe hydrographic network of volcanoes has an impact as much on the constructive as on the destructive processes. This study is potentially rich in information. Volcanic hydro-geomorphology studies volcanic hydrographical system from a naturalist and multiscale approach.On volcanoes, the analysis of processes that are produced in volcanic streams, during eruptions or rest periods, shows that the hydro-volcano-geomorphologic (HVG) hazards are numerous and cannot be reduced to simple flooding. All of the different HVG destructive phenomena act to evacuate the excess of volcanic material. The morphological impact is more definite than the ‘standard’ water floods. As a result, the threat of volcanic streams is significant because it is frequent, spontaneous and cannot always be predicted. Which bring us to the following question: are volcanic streams more dangerous than eruptions?If the HVG risks have been neglected by the society in favor of the crater phenomena, it has not always been so in the Lesser Antilles. The vocabulary of the native Caribbean (Kalinago) that has reached us through the Carib-French dictionary of Father Breton (1665) is rich in information. It allows us to identify several gradients in the hydro-geomorphologic factors: meteorological crisis, stability of land and torrential phenomena intensity. The Kalinago’s vocabulary contains other words from different domains in geosciences, but none which refer to volcanic eruptions. This amerindian society probably perceived volcanoes on another time scale than ours: a temporal scale adapted to the impact of hazards, their danger.
Flooding in Jamaica with assessment of riverine inundation of Port Maria, St Mary
Authors: Mandal Arpita , Maharaj Anuradha 
Published: March 2013

Abstract
Flash flooding, from extreme rainfall is one of the major natural disasters affecting Jamaica and other small island states of the Caribbean. Flooding in Jamaica is mainly riverine, coastal and depression with the major coastal towns being affected owing to their location on low lying areas. Such localization is driven by increase in urbanization and tourism along the coastal areas. The present work aims in a broad discussion of the flooding in Jamaica with special reference to riverine flooding of Port Maria, the capital of St Mary, one of the parishes lying in the high rain zone of the island and being affected by repeated events of flooding. Analysis of the extreme rainfall event of November 23rd–24th, 2006 shows that it exceeded the 30 yr annual rainfall of the area and the 100 yr return period as calculated from 30 yr annual rainfall data for the island. The Port Maria river lacks a gauging station to monitor flow data and flood discharge peaks. Several methods are used to calculate the run-off in such small ungauged catchments. In this study the Soil Conservation Systems Curve Number (CN) method was used to calculate the run-off from the measured rainfall data using empirical equations. Results show an unprecedented high of 13–14 inches affecting the buildings and other infrastructures, leading to the collapse of a newly constructed bridge over the river Port Maria. The town continues to get flooded from intense short duration rainfall continuing to affect life and property. Flood plain maps exist for the larger watersheds of the island but smaller yet flood prone ones have not been mapped so far. Hence this becomes very important to create a floodplain map showing the extent of the runoff from rainfall with respect to the buildings and other infrastructures of the area. The present work thus aims in creating a spatial distribution map of the runoff from the rainfall measurements aiding in developing a no build zone for this and for other low lying coastal areas of the island.

Abstract
In this paper we present and discuss new investigations performed on both the magmatic basement and the sedimentary formations of La Désirade. We report structural and sedimentary evidences for several episodes of deformation and displacement occurring prior to the present day tectonics. The main faults, respectively N130 ± 10°, N040 ± 10° and N090 ± 10°, previously considered as marker of the current tectonic regime corresponds to reactivated tectonic structures developed first during late Cretaceous compression and second during Pliocene to early Pleistocene extension. We demonstrate also the importance of late Pliocene-early Pleistocene and middle-late Pleistocene vertical movements in this part of the Lesser Antilles fore-arc as well as the role of compressive tectonics in the over thickened character of the arc basement in the Guadeloupe archipelago.
Two novel aspects of the kinetics of gene expression including miRNAs
Authors: Zhdanov Vladimir 
Published: March 2013

Abstract
In eukaryotic cells, many genes are transcribed into non-coding RNAs. Small RNAs or, more specifically, microRNAs (miRNAs) form an abundant sub-class of such RNAs. miRNAs are transcribed as long noncoding RNA and then generated via a processing pathway down to the 20–24-nucleotide length. The key ability of miRNAs is to associate with target mRNAs and to suppress their translation and/or facilitate degradation. Using the mean-field kinetic equations and Monte Carlo simulations, we analyze two aspects of this interplay. First, we describe the situation when the formation of mRNA or miRNA is periodically modulated by a transcription factor which itself is not perturbed by these species. Depending on the ratio between the mRNA and miRNA formation rates, the corresponding induced periodic kinetics are shown to be either nearly harmonic or shaped as anti-phase pulses. The second part of the work is related to recent experimental studies indicating that differentiation of stem cells often involves changes in gene transcription into miRNAs and/or the interference between miRNAs, mRNAs and proteins. In particular, the regulatory protein obtained via mRNA translation may suppress the miRNA formation, and the latter may suppress in turn the miRNA-mRNA association and degradation. The corresponding bistable kinetics are described in detail.

Abstract
The role of vegetable and fruit consumption in the aetiology of kidney cancer was analyzed using data from a case-control study conducted in two centres in the Czech Republic between 1999 and 2003. The study comprised 300 patients with newly diagnosed, histologically confirmed kidney cancer and 335 controls. Information on dietary habits was obtained using a standardized food frequency questionnaire including 23 food items. Odds ratios (ORs) and 95% confidence intervals were calculated using logistic regression models. A strong protective effect of vegetables consumption on renal cell carcinoma risk was observed among people with high consumption of fresh vegetables (OR 0.42 95% CI (0.29–0.60)) and cooked vegetables (OR 0.71, 95% CI (0.51–1.00)). The protective role of fresh fruit was significant as crude OR 0.71, 95% CI (0.50–1.00), but after adjusting for the main risk factors no association was found (OR 1.08, 95% CI (0.71–1.64)). The protective role of pickled vegetables disappeared after adjustment for the main risk factors.

ABSTRACTIntroductionSinonasal cancers have variable biological behavior and outcomes. The physical proximity of several critical structures renders radiotherapy challenging for these cancers.PurposeTo report our early experience of helical tomotherapy (HT)-based image-guided intensity-modulated radiation therapy (IMRT) in midline sinonasal cancers.Materials and methodsPatients with midline sinonasal cancers were accrued on a prospective generic protocol of HT-based IMRT. HT plans were evaluated using standardized indices. All patients were followed up clinicoradiologically. Local control was defined as absence of failure (recurrence/ progression) in the tumor bed, whereas distant disease control was defined as absence of distant metastases. All time-to-event data was analyzed using Kaplan-Meier methods.ResultsTen patients with a median age of 42 years (range: 29-62 years) were included. HT was able to achieve excellent target volume coverage, good high-dose conformality with exquisite sparing of organs at risk. The acute toxicity of HT was generally mild and self-limiting. Seven patients experienced acute grade I-II ocular toxicity that responded to topical steroids, while one patient developed grade III conjunctivitis. The same patient later developed bilateral cataract necessitating extraction (late grade III ocular toxicity). No patient experienced dry-eye syndrome, corneal opacity or blindness. With a median follow-up of 27 months (interquartile range: 13-35 months), the 3-year Kaplan-Meier estimate of local progression-free survival, distant metastases-free survival, disease-free survival and overall survival was 59.3, 90, 53.3 and 90% respectively.ConclusionHT-based image-guided IMRT for midline sinonasal cancers achieves good high-dose conformality and is associated with mild, self-limiting acute ocular toxicity, minimal late morbidity with acceptable disease control.How to cite this articleGupta T, Wadasadawala T, Phurailatpam R, Paul SN, Murthy V, Budrukkar A, Ghosh-Laskar S, Nair D, Pai P, Chaturvedi P, Agarwal JP.

Head and Neck Cancer Burden in India
Authors: Kulkarni Manik Rao 
Published: March 2013

ABSTRACT

Introduction
Head and neck cancer in India has distinct demographic profile, risks factors, food habits, and personal and family history. They are emerging as major public health problems in India, which are lifestyle related, have a lengthy latent period and need dedicated infrastructure and human resource for treatment. Need based and coordinated research for understanding the threats to the nation from chronic diseases such as head and neck cancers and ways to defy such threats will assume increasing importance.

Magnitude of problem in India
Overall, 57.5% of global head and neck cancers occur in Asia especially in India. Head and neck cancers in India accounted for 30% of all cancers. In India, 60 to 80% of patients present with advanced disease as compared to 40% in developed countries. A slow decline in the incidence of most of head and neck cancers has been documented in India.

Management of head and neck cancers in India
The problem of managing head and neck cancers in India is somewhat different, as compared to the west. The major shortcoming is to cope up, with the loss to follow-up, which makes the task of conducting and reporting the end results of clinical trials awfully difficult.

Conclusion
The highest priority for cancer control should be given to the burden of head and neck cancer in India. The emphasis should be on preventing the onset and detecting the disease at an early stage. In developing countries like India, implementing cancer control activities has to be prioritized, making optimal use of limited resources to deliver the utmost benefit to the largest number of people.

Published: March 2013

ABSTRACTBackgroundOcular myiasis or ophthalmomyiasis means the infestation of the eye on a background of foul smelling skin infection or advanced case of skin cancers. Older people, immunocompromised patients with orbital carcinomas, diabetics and patients on immunosuppressive therapy, poor environmental sanitation and personal hygiene are prone for this infestation.Case reportA 72-year-old female reported to us with extensive myiasis of the right eye. Lesion of 4 × 4 cm at the medial canthus and the right maxillary region with the right nasal dorsum was infested with maggots. All the larvae were removed with forceps and the wound debrided.InterventionThe larvae were present for a week and on healing the wound was evaluated with computed tomographic (CT) scan paranasal sinuses with axial and coronal section. As no bony erosion and intracranial extension was noted hence considering the age and diabetic status surgery was not contemplated and the lesion was irradiated.ConclusionOcular myiasis is a rare disease, accompanied by marked inflammatory reactions and secondary bacterial infections with massive destruction and life-threatening consequences, such as intracranial invasion. Prompt management with debridement and radical antibacterial therapy is essential.How to cite this articleNaik SM, Nanjundappa A, Halkud R, Gupta S.

Regional Grafts for Closure of Postsurgical Defect in Anterior Maxilla: Versatility of Chin Graft and Local Rotational Flap
Authors: Manekar Varsha Sunil 
Published: March 2013

ABSTRACTThe management of postsurgical defect is a challenge for the maxillofacial surgeon. With the success of various autogenous grafts and surgical flaps the reconstruction surgery creates definitive results. This article is a case report of reconstruction of osseous defect and closure of soft tissue fenestration in the right anterior maxilla. An autogenous corticocancellous graft from the mandibular symphysis is used for reconstruction of the osseous defect of around 15 × 15 mm. The mucosal fenestration of around 10 × 10 mm is closed by rotational flap based in the labial sulcus. The defect and the donor site healed uneventfully. Both osseous and mucosal defect healed with esthetic results. Thus, the regional flaps prove the versatility by convenience of graft taking, no donor site morbidity and biological resemblance of tissues.How to cite this articleManekar VS.

ABSTRACTAims and objectivesTo compare the efficacy of urinary human chorionic gonadotropin (uhCG)vsrecombinant human chorionic gonadotropin (rhCG) for triggering ovulation in gonadotropinreleasing hormone (GnRH) antagonistin vitrofertilization (IVF) cycle.Materials and methodsTwo hundred patients who underwent GnRH antagonist IVF/ICSI cycles were analyzed, 100 of them received recombinant hCG 250 μg (injection overtrelle) and another group of 100 received urinary hCG (injection ovutrig) either 5000 IU or 10,000 IU for final oocyte maturation and ovulation trigger. The primary outcome measured was total oocytes retrieved and the secondary outcome measured 09 was the maturity rate fertilization rate, cleavage rate and clinical pregnancy rates were also compared.ResultsAge, day 2 follicle stimulating hormone (FSH) and total dose of rFSH were comparable between the groups. There were no significant differences between the groups in terms of the mean number of oocytes retrieved per follicle (uhCG; 12.5, rhCG; 12.09, p-value-0.6698). Similarly, there was statistically no difference in any of the other parameters studied between the two groups. That is number of mature oocytes, number of fertilized oocytes and number of cleaved oocytes, as the p-value was not significant. The clinical pregnancy rate was somewhat higher in the uhCG group but was not statistically significant. Both treatments were well tolerated and there was no significant side effects for either drug.ConclusionThere is no difference in clinical outcomes between urinary and recombinant hCG for induction of final oocyte maturation. Additional factors, including the cost, drug availability and ease of administration, should be considered, when choosing gonadotropin type.How to cite this articleSidhmalswamy GA, Srinivas MS, Dipika K, Anu K, Rao KA, Mekhala D.
