Giant Cell Tumor Arising from Anterior Arc of First Rib- A Rare Presentation
Authors: Pandey S , Thakur B , Chhetri P
Published: September 2018

We report a case of Giant Cell Tumor (GCT) arising from anterior are of first rib along with literature review which was treated with excision of rib through its normal margin along with tumor mass. GCT of rib is rare and if found mostly arises from the posterior aspect. However, GCT should be considered as differential diagnosis when bony mass is present in the anterior are of rib. It poses surgical challenge for excision because of the delicate and vital neurovascular structures passing above it between clavicle and first rib.

Keywords: first rib, giant cell tumor.

Prospects of Jugular Venous Pulse Assessment
Authors: Bhattarai M D
Published: September 2018

There is no controversy regarding the current clinical method of examination of waveform of jugular vein pulse. However there are limitations of clinical assessment of central venous pressure by jugular vein pressure measurement from the level of sternal angle. There are variations in the reported distances from sternal angle to right atrium as well as to upper limit of JVP. In erect position, anterior end of fourth intercostal space is at about the level of mid-right atrium. In patients with visible JVP at neck in erect position, measurement of CVP can be done more accurately directly from the anterior end of fourth intercostal space. For others, the position of mid-right atrium can be marked in lateral chest wall first in erect position at the mid-point of an anteroposterior line from anterior end of fourth intercostal space to back. Subsequently in reclining position, the vertical height of venous pressure can be measured from the horizontal plane of the midpoint marked at lateral chest wall to visible upper limit of JVP. Such measurement can be done in a more reliable way with venous pressure (VP) manometer with its indicator rod at the horizontal plane of mid-right atrium and with its horizontal surface at upper limit of JVP. The venous pressure manometer can also be used to measure relatively less reliable upper limb venous pressure (ULVP), as indicated by the vertical distance at which veins of upper limb collapse, especially when JVP is not visualized due to subnormal CVP as in hypovolemia.

Keywords: CVP, JVP, right atrium, sternal angle, upper limp venous pressure, venous pressure, venous pressure manometer

Treatment provider’s role: Preparing students to return to school
Authors: Hennen Bob V
Published: September 2018

With the continuous growth of the collegiate recovery movement, treatment providers are considering a return to school a viable option for people in early recovery and it is often the goal of the student to return to school as quickly as possible following treatment.  The barriers to and skills needed for recovery maintenance and school completion are interconnected and should be addressed simultaneously in treatment with students planning to return to school.  This presentation is designed to address the treatment provider’s role in preparing a student to return to school by exploring methods to assess for developmental barriers and resources and build skills for both substance use recovery maintenance and the successful navigation of higher education.

Utilizing the experience of students and staff members engaged in recovery support services empowers CRPs to implement alcohol and other drug (AOD) programming for the general student population. This presentation will outline how CRPs can implement education programs within their university in order to provide wider support and resources as well as challenge injunctive norms on campus. By employing various education initiatives, CRPs can reach a broader range of students while also attaining sustainability within the university structure.
Community Colleges: The Next Frontier of Recovery Support at Institutions of Higher Education
Authors: Jones Erin K
Published: September 2018

In 2016, TYR could identify only six community colleges offering recovery support programs and services. Based on this finding, TYR identified a need for pilot programs to better understand programmatic models that may be effective for supporting students in recovery at community colleges. TYR’s Bridging the Gap grant program supports these pilot programs and is intended to act as a catalyst for building capacity for recovery support on community college campuses across the U.S. The goal of the program is two-fold; first, to help more 2-year institutions initiate recovery support programs and services and second, to study what programs and services are viewed as helpful and useful to students in recovery so that best practices can be shared as the field develops. This session provided a recap of TYR’s 2016 research, observations from Year 1 of the grant program, and a discussion on survey responses on institutional attitudes and student engagement in recovery support on 2-year campuses.

The Challenge of Oral History to Environmental History
Authors: Williams Brian , Riley Mark
Published: September 2018

Oral history has much to offer environmental history, yet the possibilities and promises of oral history remain underutilised in environmental history and environmental studies more broadly. Through a reflection on work in environmental history and associated disciplines, this paper presents a case for the strength and versatility of oral history as a key source for environmental history, while reflecting on questions of its reliability and scope. We identify three major insights provided by environmental oral history: into environmental knowledge, practices and power. We argue that, rather than being a weakness, the (inter)subjective and experiential dimensions of oral accounts provide a rich source for situating and interrogating environmental practices, meanings, and power relations. Oral history, moreover, provides a counterweight to a reliance on colonial archives and top-down environmental accounts, and can facilitate a renewal - and deepening - of the radical roots of environmental history. Furthermore, as a research practice, oral history is a promising means of expanding the participatory and grassroots engagement of environmental history. By decentring environmental expertise and eroding the boundaries (both fictive and real) of environmental knowledge production, oral environmental histories can provide key interventions in pursuit of a more just, sustainable world.
Napsterisierung und Venterisierung
Authors: Kuhlen Rainer
Published: September 2018

We use the alternative concepts of napsterization (information sharing) and venterization (commerzialization and control) to characterize the main trends within information markets for organisation, production and usage of knowledge. In particular, “napsterization” will be described with respect to Napster itself, to the DVD conflict, to Digital Rights Management for digital products such as E-books, and to problems and potentials of information sharing in scientific environments. Assuming that knowledge cannot and should not be fully controlled in electronic spaces we suggest that the principles of information sharing, distributed information work, pricing for information, and value-added services should be adopted by the information economy rather than continuing a costly and unwinnable information war" between napsterizers and venterizers.
Die Globalisierung von Rechten an geistigem Eigentum und der Nord-Süd-Konflikt
Authors: Frein Michael
Published: September 2018

The article discusses the Agreement on Trade Related Aspects of Intellectual Property Rights (TRIPs) of the World Trade Organisation (WTO) as an instrument for the globalisation of intellectual property rights. It focuses on the provisions of TRIPs Art 27.3 (b), which contains global rules for the patenting of life, and the question of access to medicines for the poor in developing countries. By analysing the underlying economic and political interests of the industrial countries and multinational corporations, which have formed the provisions of the TRIPs- Agreement, it is argued that higher standards in intellectual property rights, especially patents, advantage the rich and disadvantage the poor. Therefore there is an urgent need to change the TRIPs-Agreement in line with the interests and in favour of developing countries. The article shows that there are several suggestions for the current negotiations made not only by NGOs, but also by governments of developing countries.

In the last century, science was not only a dominant factor in society, but helped also to create incredible weapon arsenals: Nuclear weapons, radar, computers, operations research, missiles, lasers have been established for warfare purposes Ieading to a narrow relationship between national security and science, especially in the United States. Scientists not only made scientific discoveries, but were also instrumental in advising their governments to develop new weapons leading to an qualitative arms race that never stopped. On the other hand, scientists using their reputation, their international contacts and their knowledge helped to establish arms control regimes and disarmament to restrict or to ban the use of weapons of mass destruction. The speed of scientific progress and the proliferation of materials, knowledge and individuals seems not to slow down. New military applications based on scientific knowledge are likely: Computers, molecular biology, electronic communication, space technologies could also be put to evil purposes. Bio-weapons, information warfare, precision munitions, encryption etc. can support asymmetrical warfare but also be used as new powerful force multipliers. New ways to contro! cruel weapons uses have to be established in the new century. lt would be the responsibility of scientists to help mankind to ban new devasting weapon applications.

Appraising and developing ST-X field determination of uncertainties by DST analysis
Authors: Vu Hung Viet , Mai Lan Cao
Published: September 2018

A subsurface uncertainties is a possible future event, which, if occurs, would affect project objectives either negatively or positively. For any given model or event, the uncertainty is the range of variation of the component parts and possible outcomes. It could be quantified approximately by either analytical model or in a more cumbersome one such as numerical approach. This paper summarizes thedetermination ofuncertainties by DST analysis in appraising and developing the ST-X gas condensate field, which is offshore Vietnam in Block 15-1O. Drill Stem Test (DST) results show that the S field has moderate to low permeability, multiple flow boundaries/barriers, and at least 2 PVT regions. To understand the impact of these and other important reservoir parameters on ultimate gas and condensate recovery and well count, the uncertainties has to be well evaluated and understood. The study demonstrates that there is a wide range of possible ultimate gas and condensate recoveries and well counts. The top causes for this wide range are permeability and flow boundaries/barriers. In addition to the subsurface risks, drilling cost of a ST-X well is very high. The high well cost in combination with the field being offshore, having low permeability and possibly numerous reservoir compartments dramatically increase the risk of a full field development.
The effects of rainfall on the stability of soil slopes in Khanh Vinh district, Khanh Hoa province
Authors: Nguyen Danh Thanh , Dau Ngo Van , Ta Dung Quoc
Published: September 2018

This study presents a procedure for calculating the change of the safety factor for unsaturated slopes of homogenous, residual soils suffering from rainfall infiltration within Khanh Vinh district, Khanh Hòa province. Rainfall is supposed as a main trigger caused failure of the potential sliding slopes. Rainwater into the slope due to infiltration caused an increase in moisture content and negative pore water pressure; a decrease in matric suction and in shear strength on the failure surface. Thus, slopes are reduced stability and can be failed. Soil permeability and rainfall intensity were found to be the primary factors controlling the instability of slopes due to rainfall, while the initial water table location and slope geometry only played a secondary role. A numerical model of analysis coupled seepage-stability used to simulate the seepage and slope stability under conditions of specific environment such as soil permeability, rainfall intensity, water table location and slope geometry in the study area. The relationships between safety factor and rainfall intensity, soil permeability, angle slope, high slope were identified to provide a good indication for the management of landslide hazards under the effects of rainfall.
Coastal erosion in go Cong Dong, Tien Giang
Authors: Bui Vinh Trong
Published: September 2018

Mangrove forest and dike system play an important role on protecting people who live in the lowland coastal areas. Go Cong Dong coastal zone is located in the eastern most of Tien Giang province, which surfered severe coastal erosion and storm surges in the northeast monsoon season. In order to investigte coastal erosion in this area, satellite images were analyzed from 1991 to 2014. Sediment samples, water samples were collected and tested to seek the reasons of eroded areas. The analysis results of satellite images showed that Go Cong Dong coastline (Vam Lang to Tan Thanh ward) has been eroded seriously with erosion rate from 10-15m/year. The results of numerical modeling illustrated that the main reasons for this hazardous phenomenon are based on natural conditions such as wind waves andtidal currents in the northwest monsoon season. In the northeast monsoon season, wave height is relatively high fluctuating around 0.7m to 0.8m; in contrast, in the southwest monsoon season the wave height has been only seen 0.2- 0.3m. The predicted rate of changes was also conducted, whereas Vam Lang-Kieng Phuoc is soon coming to be eroded. Otherwise, degradation of mangrove forest should be concerned by high concentration of arsenic in sediment alongshore and shrimp pond.

Remittances and exchange rate - Empirical evidence from emerging economies
Authors: Nguyen Canh Phuc
Published: September 2018

The exchange rate plays an important role to trade, investment and macroeconomic risks of open economies. There are many factors that affect the exchange rate such as inflation, interest rates, balance of payments where remittance flows receive more and more attention of economists due to their increase in their values, particularly in emerging economies. This study uses data from 21 countries which are classified as emerging markets in the period between 2001 and 2013 to investigate the impacts of remittances on exchange rate. Through panel data estimations, we found that remittances increase the value of the local currencies, which is not altered by the 2008 global financial crisis.
Analyse the disk closed cycle MHD generator performance with the influence of channel characteristics
Authors: Le Kien Chi
Published: September 2018

The enthalpy extraction ratio is one of the most significant parameter of a disk closed cycle MHD generator. There are two methods to improve the enthalpy extraction, those are the increase of channel cross-sectional area ratio and the implementation of inlet swirl. In this study, the mechanism of enthalpy extraction improvement has been confirmed by the two-dimensional numerical calculation. As a result, by increasing the channel cross-sectional area ratio of the disk MHD generator, the increase of static pressure and the velocity deceleration can be suppressed due to the Lorentz force, and it is possible to maintain a high flow velocity inside the channel and a high Hall parameter. The implemention of inlet swirl is possible to maintain a low static pressure inside the channel and the enthalpy extraction ratio rises due to the increase of Hall parameter. In addition, the channel cross-sectional area ratio increases due to the swirl implementation, the static pressure is kept low, and the channel inlet flow velocity increases. This also leads to the increase of enthalpy extraction ratio, that is the increase of output power.

Published: September 2018

In this study, the effects of temperature, pH, enzyme content, hydrolysis time on antioxidant activity of the hydrolysate from Tra catfish (Pangasiushypophthalmus) by-products with Alcalase® 2.4 L FG were investigated using DPPH• (2,2-diphenyl-1-picrylhydrazyl) radical scavenging method (DPPH• SM) and FRAP (ferric reducing antioxidant potential) method. The chemical composition of the Tra catfish byproducts included 58.5% moisture, 33.88% crude protein, 50.14% crude lipid and 15.83% ash (on dry weight basis). The result of antioxidant activity of the hydrolysate showed that the 50% DPPH• inhibition concentration (IC50) of the hydrolysate reached about 6775 μg/mL which was 1645-fold higher than that of vitamin C and 17-fold higher than that of BHT (Butylated Hydroxytoluene) with the degree of hydrolysis (DH) of the hydrolysate of 14.6% when hydrolysis time was 5h, enzyme/substrate (E/S) ratio was 30 U/g protein, hydrolysis temperature was 550C, and pH was 7.5. The antioxidant potential of hydrolysate using FRAP method reached about 52.12 μMTrolox equivalent which was 53-fold and 18-fold lower than those of vitamin C and BHT, respectively, when the hydrolysis time was 5h, enzyme/substrate ratio was 30 U/g protein, temperature was 500C, and pH level was 8. The result showed that the antioxidant proteolysate derived from Tra catfish by-products has the potential to be used as a natural antioxidant ingredient in nutraceutical and functional food industry.
An Image Analysis Approach to Microgrippers Displacement Measurement and Testing
Authors: Orsini Francesco , Vurchio Federica , Scorza Andrea , Crescenzi Rocco , Sciuto Salvatore Andrea
Published: September 2018

The number of studies on microgrippers has increased consistently in the past decade, among them the numeric simulations and material characterization are quite common, while the metrological issues related to their performance testing are not well investigated yet. To add some contribution in this field, an image analysis-based method for microgrippers displacement measurement and testing is proposed here: images of a microgripper prototype supplied with different voltages are acquired by an optical system (i.e., a 3D optical profilometer) and processed through in-house software. With the aim to assess the quality of the results a systematic approach is proposed for determining and quantifying the main error sources and applied to the uncertainty estimation in angular displacement measurements of the microgripper comb-drives. A preliminary uncertainty evaluation of the in-house software is provided by a Monte Carlo Simulation and its contribution added to that of the other error sources, giving an estimation of the relative uncertainty up to 3.6% at 95% confidence level for voltages from 10 V to 28 V. Moreover, the measurements on the prototype device highlighted a stable behavior in the voltage range from 0 V to 28 V with a maximum rotation of 1.3° at 28 V, which is lower than in previous studies, likely due to differences in system configuration, model, and material. Anyway, the proposed approach is suitable also for different optical systems (i.e., trinocular microscopes).

Published: September 2018

With a dearth of research on international entrepreneurship pedagogy, there is a gap in knowledge on the effectiveness of educational programs, courses, and teaching methods in stimulating and promoting international entrepreneurship practice. To address the gap, this study evaluates an experiential teaching innovation in the area of international entrepreneurship, the Global Board Game project. Designed as a Community of Practice (CoP), the project provides students the opportunity to participate in the construction of their knowledge through interactions with their counterparts in other countries. A qualitative analysis of student essays indicates that the Global Board Game project is effective in helping students achieve learning outcomes, which include defining, recognizing, and evaluating international business opportunities; designing and validating a business model based on such opportunities; and creating a plan for pursuing these opportunities. Additionally, it indicates that participation in the project enhanced students’ attitudes toward entrepreneurship as a career path.

Excessively wet conditions expose poorly drained soils to an increased potential of N loss and reduced N use efficiency. A two-year experiment with wheat (Triticum aestivum L.) was initiated in 2014 and concluded in 2016 in northeastern Missouri in the United States (USA). The objective of this experiment was to evaluate the effects of nitrapyrin and pronitridine nitrification inhibitors (NI) applied as an early or late-split application timing (40:60%) of 79 kg N ha−1 or 112 kg N ha−1 on winter wheat soil and plant N status, as well as grain yield. Both NIs had no effect (p = 0.3917) on yield, while there was an interaction between year and the urea ammonium nitrate (UAN) rate on grain yield. Yields were similar (3550 kg ha−1 to 3686 kg ha−1) in 2015 between UAN application rates. UAN at 112 kg N ha−1 resulted in a 551 kg ha−1 greater yield than UAN at 79 kg N ha−1 in 2016. Nitrapyrin and pronitridine did not significantly affect soil ammonium or nitrate–N concentrations at depths of 0–15 cm and 16–30 cm compared to the absence of NI over the period of three months after application. Nitrapyrin with UAN at 112 kg N ha−1 had the highest grain test weight. Further testing of these NIs in combination with UAN for winter wheat production is needed under different climatic and environmental conditions to develop comprehensive management recommendations.
Forestland Grabbing by the Foreigners in Hokkaido, Japan: Is It a Big Concern for Sustainable Forest Development?

Published: September 2018

A world-wide demand in large-scale land acquisition over the past decade has been discussed as a land grab for access to natural resources. Forestland grab is the dynamics of land use changes by the foreign or national entities that can enable forests and biodiversity transformations on a wider scale. In recent times, forestland grabbing performed by foreigners in the Hokkaido Island of Japan has been increasing and causing a lot of debate. Therefore, this study analyzed the social, economic, and ecological impacts of forestland grabbing by the foreigners in the Hokkaido Island of Japan, and also analyzed the land ownership rules and regulations of Japan that have an impact on the land-grabbing process. This study is formed by an analysis of public and forestry agency documents, grey and academic literatures, interview with questionnaire and practical observation in central Hokkaido, Japan. The study found out that the forestland grabs have been taking place on the Hokkaido Island using the existing Japanese policy and legal arrangements. However, some people and print media have disagreed with the treatment of forestlands as a commodity because the land and water resources are limited and also essential for the national sovereignty and local culture. On the other hand, the small-scale forestland grabbing and development activities by foreigners were totally in the grip of the local government and no significant forest and biodiversity losses have been identified so far. The study also revealed that the entry of foreign companies has augmented the local economy and tourism industries and also provided jobs for the local people. Therefore, the foreigners-based land grabs and investments have caused an immense debate, and the study would recommend the proper execution of conservation regulations at every level instead of blocking the entry of foreign entities through law.
Congestion Risk-Averse Stochastic Unit Commitment with Transmission Reserves in Wind-Thermal Power Systems
Authors: Huang Yu , Xu Qingshan , Lin Guang
Published: September 2018

The great proliferation of wind power generation has brought about great challenges to power system operations. To mitigate the ramifications of wind power uncertainty on operational reliability, predictive scheduling of generation and transmission resources is required in the day-ahead and real-time markets. In this regard, this paper presents a risk-averse stochastic unit commitment model that incorporates transmission reserves to flexibly manage uncertainty-induced congestion. In this two-settlement market framework, the key statistical features of line flows are extracted using a high-dimensional probabilistic collocation method in the real-time dispatch, for which the spatial correlation between wind farms is also considered. These features are then used to quantify transmission reserve requirements in the transmission constraints at the day-ahead stage. Comparative studies on the IEEE 57-bus system demonstrate that the proposed method outperforms the conventional unit commitment (UC) to enhance the system reliability with wind power integration while leading to more cost-effective operations.

Versatile Synthesis of Pd and Cu Co-Doped Porous Carbon Nitride Nanowires for Catalytic CO Oxidation Reaction

Developing efficient catalyst for CO oxidation at low-temperature is crucial in various industrial and environmental remediation applications. Herein, we present a versatile approach for controlled synthesis of carbon nitride nanowires (CN NWs) doped with palladium and copper (Pd/Cu/CN NWs) for CO oxidation reactions. This is based on the polymerization of melamine by nitric acid in the presence of metal-precursors followed by annealing under nitrogen. This intriguingly drove the formation of well-defined, one-dimensional nanowires architecture with a high surface area (120 m2 g−1) and doped atomically with Pd and Cu. The newly-designed Pd/Cu/CN NWs fully converted CO to CO2 at 149 °C, that was substantially more active than that of Pd/CN NWs (283 °C) and Cu/CN NWs (329 °C). Moreover, Pd/Cu/CN NWs fully reserved their initial CO oxidation activity after 20 h. This is mainly attributed to the combination between the unique catalytic properties of Pd/Cu and outstanding physicochemical properties of CN NWs, which tune the adsorption energies of CO reactant and reaction product during the CO oxidation reaction. The as-developed method may open new frontiers on using CN NWs supported various noble metals for CO oxidation reaction.

Published: September 2018

Mechanical methods to extract undesired graffiti paints on ornamental stones are efficient cleaning methods from an economical point of view. However, effort on the optimization of mechanical cleaning procedures to avoid any damage to the substrate is required for large areas. In this study, two ornamental stones with different composition and texture, and which are commonly used in Spain and Portugal were selected: Granite Vilachán and Limestone Lioz. Moreover, the most common surface finishes were selected-disc-cutting and bush-hammering to simulate the stones found in buildings. Two graffiti spray paints were selected: Blue Ultramarine and Silver Chrome. As cleaning methods, three soft-abrasive blasting procedures: Hydrogommage (mixture of air–water–micro grained silicon abrasive), IBIX (mixture of air–micro grained silicon abrasive), and dry-ice procedure (carbon dioxide ice pellets), were tested at pressure below 0.4 MPa. The methodology for evaluating the effectiveness and harmfulness of each cleaning method was based on stereomicroscopy, scanning electron microscopy, color spectrophotometry, and confocal microscopy. As result, IBIX achieved the highest level of graffiti paint extraction although this method increased the surface roughness. Conversely, cleaning based on dry-ice projection did not achieve a satisfactory extraction of the graffiti, mainly of the blue paint. Dry-ice blasting can induce acid environments and IBIX causes dust emission during the projection. Hydrogommage was the most efficient cleaning method amongst the tested procedures, because it induced the lowest roughness change and although the graffiti extraction was not complete, it achieved the highest removal level. Therefore, the most satisfactory cleaning method was that achieving a satisfactory extraction level, minimal modifications of the surface roughness, an economic suitability, an environmental integration, and lower human health risks.

Graphene is a kind of typical two-dimensional material consisting of pure carbon element. The unique material shows many interesting properties which are dependent on crystallographic orientations. Therefore, it is critical to determine their crystallographic orientations when their orientation-dependent properties are investigated. Raman spectroscopy has been developed recently to determine crystallographic orientations of two-dimensional materials and has become one of the most powerful tools to characterize graphene nondestructively. This paper summarizes basic aspects of Raman spectroscopy in crystallographic orientation of graphene nanosheets, determination principles, the determination methods, and the latest achievements in the related studies.

Published: September 2018

Through the lens of complexity theory and by utilizing the methodological framework set forth in Gander’s 1999 article regarding internal and external organizational elements of administrative intensity, this secondary data analysis study linked the internal organizational elements of administrative intensity to institutional results as evidenced by higher education student retention and graduation rates. Representing institutional investments, efforts, and outcomes from 2004 to 2014, three years of data reporting were gathered from the Integrated Postsecondary Education Data Set (IPEDS) and were then cleaned per secondary data analysis techniques. Using canonical correlation analysis, the internal elements of administrative intensity were correlated with student retention and success. Findings indicate the relationships of internal elements of higher education institutions on student retention and success, which was measured by four-year, six-year, and eight-year graduation rates. The discussion includes education policy implications.
