Methyl Termination and ATR-FTIR Evaluation of n-Si(111) Electrode towards Photoelectrochemical Cell Fabrication

We confirmed methyl termination on n-Si(111) surface by ATR-FTIR measurement, which was fabricated by a photo chloro-reaction and its methylation. The coverage of the methylation was about 63.7%, and the surface was not re-terminated by hydrogen. Photoelectrochemical properties of the n-Si(111) were measured as an electrode for a photoelectrochemical cell, and an onset potential obtaining photocurrent for the methyl terminated n-Si(111) electrode was observed as negative shift at 70 mV comparing with that of the hydrogen terminated n-Si(111) electrode. Therefore, the negative shift would be expected for improving open circuit voltage towards solar cell.
N‐Acetyl Cysteine Is Associated With Dopaminergic Improvement in Parkinson's Disease

This study assessed the biological and clinical effects in patients with Parkinson's disease (PD) of N‐acetyl‐cysteine (NAC), the prodrug to l‐cysteine, a precursor to the natural biological antioxidant glutathione. Forty‐two patients with PD were randomized to either weekly intravenous infusions of NAC (50 mg/kg) plus oral doses (500 mg twice per day) for 3 months or standard of care only. Participants received prebrain and postbrain imaging with ioflupane (DaTscan) to measure dopamine transporter (DAT) binding. In the NAC group, significantly increased DAT binding was found in the caudate and putamen (mean increase from 3.4% to 8.3%) compared with controls (P < 0.05), along with significantly improved PD symptoms (P < 0.0001). The results suggest NAC may positively affect the dopaminergic system in patients with PD, with corresponding positive clinical effects. Larger scale studies are warranted.
Primary peritoneal serous papillary carcinoma (PSPC) involving ovary and colon: Management and Treatment

We present a case report of a 47-year-old woman who was admitted to our University-Hospital following diagnosis of pelvic mass. Abdominal examination revealed a tender, palpable mass on the right iliac region. At the gynecological examination uterus was regular in size. On the left side of the uterus a mass of 9 cm was observed; its surface was irregular and no mobility was found. Abdominal CT and NMR revealed massive ascites, omental cake and increased volume of both ovaries. Patient underwent longitudinal suprombelical-pubic laparotomy. After opening abdominal cavity, a free-fluid sample was taken and the results were positive for malignant cells. Typical neoplastic localizations on both ovaries, Douglas’ peritoneum, rectum, sigmoid colon and omentum were observed. Extemporaneous histological examination diagnosed a peritoneal serous papillary carcinoma. Hysterectomy with salpingo oophorectomy, total omentectomy, appendectomy, pelvic and lumbo-aortic lymphadenectomy was performed. Retroperitoneal approach to remove the whole Douglas’ peritoneum together with the pouch malignant localizations was done. Sigmoid colon and rectum were resected. A latero-terminal anastomosis with stapler was performed. All the visible abdominal maligant lesions were cut out. No transfusion was necessary. The postoperative course was regular and after seven days the patient was discharged. Chemotherapy ended the therapeutic management (six cycles of carboplatin with paclitaxel)|. After one year the patient is in good health and instrumental investigations (Ultrasounds, TC and NMR) are negative for recurrence. Such a case is very interesting for the discrepancy between slight symptoms and severity of the disease, the solution of which was very complex requiring a skillful polyspecialized oncological team.

Parameterising Internal Camera Geometry with Focusing Distance

A study on the variation of internal camera geometry (principal distance, principal point position and lens distortion parameters) with different focus distances has been conducted. Results demonstrate that variations of parameters are continuous and predictable, allowing a new way to describe internal camera geometry. The classical constant parameters, c, x p , y p , K 1 , K 2 , P 1 and P 2 , are replaced by continuous functions, c(γ), x p (γ), y p (γ), K 1 (γ), K 2 (γ), P 1 (γ) and P 2 (γ), where γ is a variable describing the focus position. Incorporation of γ as a metadata tag (for example, Exif header) of a photograph jointly with a parameterised definition of camera geometry would allow full use of the autofocus camera function; enabling maximum effective depth of field, better match of the plane of focus with the object’s position and higher reliability. Additionally, conducted tests suggest the parameterised definition of internal geometry could help to locate and correct linear dependences between adjusted parameters, potentially improving the precision and accuracy of calibration.
Wilms’ tumor 1 mRNA expression: a good tool for differentiating between myelodysplastic syndrome and aplastic anemia in children?

ABSTRACT Objectives: To evaluate the value of Wilms’ tumor 1 mRNA (WT1) expression in the differential diagnosis of childhood myelodysplastic syndrome (MDS) and aplastic anemia (AA). Methods: This study compared WT1 expression levels in children of MDS and AA to evaluate its value in differential diagnosis. Results: WT1 overexpression rate and mean WT1 expression level were significantly higher in MDS compared to AA (P = 0.000 and P = 0.013, respectively). Patients with RCC and normal cytogenetics exhibited significantly greater portion of patients exposing WT1 overexpression, compared to all AA subtypes (P = 0.001, P = 0.000 and P = 0.001, respectively). ROC curve analysis revealed that WT1 expression could differentiate between RCC with normal cytogenetics and non-severe AA. Based on a cut-off value of 1.45%, WT1 expression provided a sensitivity of 23.2% and a specificity of 100%. Discussion: In the present study, WT1 overexpression rate was gradually decreased in RAEB group, RCC group and AA subtypes, and the mean WT1 expression level of the MDS patients was significantly higher than that of the AA group. It is very difficult to differentiate between RCC with normal cytogenetics and NSAA in children. Our results showed significant differences in WT1 overexpression rate between these two groups. When we set the cut-off value as 1.45%, WT1 expression levels could be used to differentiate between cases of RCC with normal cytogenetics and NSAA in children. Conclusion: WT1 expression might be useful for distinguishing between myelodysplastic syndrome and aplastic anemia in children.
Public private partnership - a way of overcoming the budget process investment restrictions in european transport infrastructure

One of the ways to overcome, to some extent, the budgetary restrictions on the state's financial resources for investment in transport infrastructure is a public-private partnership. Thus, we considered it useful to express our own opinions as well as reiterating the presentation of world and European experiences by experts in the field of benefits and risks of public-private partnership, and the study which useful lessons can be drawn. We are not just for copying or taking of these experiences, due to the concrete conditions of each country, but certain aspects can be adapted creatively. Consequences of non-critical acquisition strategies developed by others in other circumstances can sometimes have unforeseen negative impacts. International comparisons are useful when account is taken with caution due to both their parts, namely comparisons over time and space comparisons. Some items may be useful but that some countries have common objectives with other countries, especially those related to European integration, and that certain processes may be concurrent in two different countries.
Nano meter stepping drive of surface acoustic wave motor

A high resolution, from nanometer to sub-nanometer, stepping drive of a surface acoustic wave (SAW) motor is presented in this paper. A step displacement was controlled easily by a number of driving waves from centimeter order to nanometer order. Reduction of the driving waves down to 25 cycles, at 100 V/sub peak/ driving voltage and 30 N pre-load condition, brought about 2 run stepping drive with our experimental setup at open loop condition. We also demonstrated a sub-nanometer stepping drive. These experimental results indicate that the surface acoustic wave motor has subnanometer positioning ability with centimeter stroke.
How to read and treat online public discussions among ordinary citizens beyond political mobilisation. Empirical evidence from the Russian-language online forums

Online debates among ordinary people discussing current affairs are typically viewed through the lens of political mobilisation and dismissed on various grounds - due to their unintelligibility, incivility, lack of argument or polarisation and fragmentation effects. It is believed that conversational discourses cannot meet the Habermasian conditions of delib- erative democracy and therefore have little value, either for decision-makers or political de- mocratisation. By providing empirical data from the analysis and comparison of three cases of real-life public debates that occurred on Russian-language online forums, this paper at- tempts to dispute the assumption that such discussions are non-deliberative. It is argued that the very conversational nature of online discussions might be their main value as a manifesta- tion of active citizenship from below.
Long-term lightcurves from combined unified very high energy γ-ray data

Now at Erlangen Centre for Astroparticle Physics, Erwin-Rommel-Str. 1, 91058 Erlangen, GermanyReceived ; acceptedABSTRACTContext. Very high-energy (VHE, E>100GeV) γ-ray data are a valuable input for multi-wavelength and multi-messenger (e.g. com-bination with neutrino data) studies.Aims. We aim at the conservation and homogenization of historical, current, and future VHE γ-ray-data on active galactic nuclei(AGN). Methods. We have collected lightcurve data taken by major VHE experiments since 1991 and combined them into long-termlightcurves for several AGN, and now provide our collected datasets for further use. Due to the lack of common data formats inVHE γ-ray astronomy, we have deﬁned relevant dataﬁelds to be stor ed in standard data formats. The time variability of the combinedVHE lightcurve data was investigated, and correlation with archival X-ray data collected byRXTE/ASM tested.Results. The combination of data on the prominent blazar Mrk421 from diﬀerent experiments yields a lightcurve spanning morethan a decade. From this combined dataset we derive an integral baseline ﬂux from Mrk421 that must be lower than 33% of the C rabNebula ﬂux above 1TeV. The analysis of the time variability y ields log-normal ﬂux variations in the VHE-data on Mrk421.Conclusions. Existing VHE data contain valuable information concerning the variability of AGN and can be an important in-gredient for multi-wavelength or multi-messenger studies. In the future, upcoming and planned experiments will provide moredata from many transient objects, and the interaction of VHE astronomy with classical astronomy will intensify. In this con-text a uniﬁed and exchangeable data format will become incre asingly important.

Understanding the Education Choices of Public Sector Employees: The Relative Importance of Time and Money

Australian workers are constantly reminded of the desirability of upgrading their skills in a rapidly changing work landscape. However, comparatively little is known about the relative importance of the factors impacting on the employees’ decisions to undertake further education. This paper presents the results of an experimental choice analysis of workers’ decisions to undertake formal courses of study. This novel approach affords the opportunity to consider factors beyond the economic domain. Results include the development of a model of employee preferences and estimates of willingness to pay for study programs.
Economic analysis on substitution of paper chart with ECDIS on board for Turkish Flag Ships

ECDIS as a real-time navigation system integrating variety of charts and navigation-related information that replaces the usage of paper chart. Nowadays, ECDIS usage is getting more recognized as being used for both navigation and collision avoidance tasks. In this consideration, Turkish ship management companies are at the right cornerstone to take a decision for the substitution of paper chart with ECDIS. Cost factor has a significant role during the selection process and it needs to be optimized with cost-benefit ratios of each alternative. This study originally tends to describe decision making process with alternative solutions that could be applied to ship’s bridge operations. By utilizing multi-criteria decision making model, it is aimed to facilitate the selection of two alternatives with “Analytic Hierarchy Process (AHP)”. Consequently quantifying the influence of related factors to the selection of two alternatives for Turkish management companies, a hierarchical analysis framework is developed and applied by AHP method.
High Order Mimetic Finite Difference Operators Satisfying a Gauss Divergence Theorem

High order mimetic finite difference operators that satisfy a discrete extended Gauss Divergence theorem are presented. These operators have the same order of accuracy in the interior as well as the boundary, no free parameters and optimal bandwidth. They are constructed on staggered grids, using weighted inner products with a diagonal norm. We present several examples to demonstrate that mimetic finite difference schemes using these operators produce excellent results.
Future Proofi ng Asset Informati on i n Transportati on Infrastructure P rojects

Over the last decade in Western Australia (WA) several mega Liquefied Natural Gas (LNG) mega-projects totaling in excess of $100 billion in value have been constructed and now entering their operational phase. However, low productivity levels contributed to significant increases in their capital expenditure (CAPEX). In particular, the Electrical, Instrumentation and Control Systems (EICS) information ‘as-built’ documentation provided at ‘hand-over’ for commencement of the operational phase does not often reflect what has been actually installed. As a result, this can adversely impact productivity and operational expenditure as well jeopardize the asset’s integrity. Traditional paper based methods such as Computer-AidedDesign (CAD) have been relied upon to create asset information for ‘hand-over’. A reliance on the use of CAD to document for EICS (e.g., specifications, and ‘as-built’) increases the propensity for errors, omissions and information redundancy. Attending to issues of this nature during the construction of the asset can result in scope changes, losses in productivity, and increases in project costs. This paper presents preliminary observations from a research project that is examining the nature of EICS documentation provided at ‘hand-over’ for the operation mega LNG projects. Using a case study, the ‘as-built’ documentation for a domestic gas metering, which formed an integral part of an LNG plant’s production process is examined. Issues hindering productivity during the production of the documentation, communication and information exchanges, and change management involved with the deliver of the EICS are presented. In addressing problems identified in the case study, it is suggested that if LNG plants are to make headway to being ‘future-proofed’, then their EICS should be digitized (i.e. process of converting information into a digital format) using a Systems Information Model (SIM). The use of SIM to ensure effective and efficient production and management of EICS information throughout an LNG asset’s lifecycle, and will contribute towards safeguarding its integrity. 1 Professor, School of Civil and Mechanical Engineering, Curtin University Perth, WA, Australia.

The Effect of Toroidal Magnetic Fields on Solar Oscillation Frequencies

Solar oscillation frequencies change with the level of magnetic activity. Localizing subsurface magnetic field concentrations in the Sun with helioseismology will help us to understand the solar dynamo. Because the magnetic fields are not considered in standard solar models, adding them to the basic equations of stellar structure changes the eigenfunctions and eigenfrequencies. We use quasi-degenerate perturbation theory to calculate the effect of toroidal magnetic fields on solar oscillation mean multiplet frequencies for six field configurations. In our calculations, we consider both the direct effect of the magnetic field, which describes the coupling of modes, and the indirect effect, which accounts for changes in stellar structure due to the magnetic field. We limit our calculations to self-coupling of modes. We find that the magnetic field affects the multiplet frequencies in a way that depends on the location and the geometry of the field inside the Sun. Comparing our theoretical results with observed shifts, we find that strong tachocline fields cannot be responsible for the observed frequency shifts of p modes over the solar cycle. We also find that part of the surface effect in helioseismic oscillation frequencies might be attributed to magnetic fields in the outer layers of the Sun. The theory presented here is also applicable to models of solar-like stars and their oscillation frequencies.
Generation of Drawing Sensation by Surface Acoustic Wave Tactile Display on Graphics Tablet

This paper describes pen interface using a surface acoustic wave tactile display. Using the display, tactile sensation like a feeling of drawing with a charcoal can be generated. Combined with a graphics tablet with an LCD, it is possible to generate both visual information and tactile sensation dynamically. To add reality of sensation, control referring to m-sequence random number is proposed and described in this paper. Measurement results of pen vibration during rubbing the display with the reference and those without it were compared. FFT analysis results of the pen vibration are also compared.
Implication of Quinazoline-4(3H)-ones in Medicinal Chemistry: A Brief Review

Quinazoline, a heterocyclic compound, has been extensively studied and used in certain specific biological activities. The quinazoline-4(3H)-one and its derivatives constitute an important class of fused heterocycles that are found in more than 200 naturally occurring alkaloids. With passage of time, newer and more complex variants of the quinazolinone structures are being discovered. The stability of the quinazolinone nucleus has inspired researchers to introduce many bioactive moieties to this nucleus to create new potential medicinal agents. With a view to explore the versatile lead molecule 4(3H)-quinazolinones, a series of novel 2-methyl-3-(1’3’4-thiadiazole-2- yl)-4-(3H) quinazolinones have been synthesized by reacting 2-amino-5-aryl/alkyl-1’3’4’-thiadiazoyl with 2-substituted benzoxazin-2-one. The designed compounds have shown antibacterial activity on Staphylococcus aureus, Bacillus subtilis and Escherichia coli. In the journey of a compound to be established as a lead and finally to a drug, the problem of solubility is a major challenge for medicinal chemists and formulation scientists. The present review has touched all these issues with a hope that some of the quinazoline derivative with sufficient bioavailability could help us to counter the menace of antibiotic resistance.
A Bayesian approach to correct for unmeasured or semi-unmeasured confounding in survival data using multiple validation data sets

Purpose: The existence of unmeasured confounding can clearly undermine the validity of an observational study. Methods of conducting sensitivity analyses to evaluate the impact of unmeasured confounding are well established. However, application of such methods to survival data (“time-to-event” outcomes) have received little attention in the literature. The purpose of this study is to propose a novel Bayesian method to account for unmeasured confounding for survival data. Methods: The Bayesian method is proposed under an assumption that the supplementary information on unmeasured confounding in the form of internal validation data, external validation data or expert elicited prior distributions is available. The method for incorporating such information to Cox proportional hazard model is described. Simulation studies are performed based on the recently published instrumental variable method to assess the impact of unmeasured confounding and to illustrate the improvement of the proposed method over the naïve model which ignores unmeasured confounding. Results: Simulation studies illustrate the impact of ignoring the unmeasured confounding and the effectiveness of our Bayesian approach. The corrected model had significantly less bias and coverage of 95% intervals much closer to nominal. Conclusion: The proposed Bayesian method provides a useful and flexible tool in incorporating different types of supplemental information on unmeasured confounding to adjust the treatment estimates when the outcome is survival data. It out-performed the naïve model in simulation studies based on a real world study.
THE EFFECT OF PULSE AND VOLTAGE ON UNALLOYED IRON SURFACE DURING SINTERING ON THE CATHODE OF GLOW DISCHARGE

Atomized iron powder was compacted at 500 MPa and sintered in a plasma atmosphere with the purpose to investigate the effects occurred on the surface of the samples with temperatures varying from 900 to 1100 oC, voltage ranging from 400 to 700 V with time switched on (Ton) of 80, 110 and 140 μs for each voltage level. These samples were sintered in DC plasma compound of hydrogen and argon using the cathode geometry. The samples have also been processed in a conventional system just for comparative effects. They have presented a significant atomic mobility on the surface promoting a decreasing porosity to a voltage level around 700 V. However, when some samples were sintered at 400 V with low Ton their surfaces presented a cluster of iron atoms in a spherical shape due to low kinetic energy of ions striking the samples.
