The article aims at presenting and assessing the role of state-financed grants in the Armenian-Russian scientific ties development. Armenian-Russian relations have a long history of collaboration and capture nearly all fields starting from cultural-humanitarian to military-political ones. Scientific cooperation is amongst the most rapidly developing aspects of bilateral relations. Since 2012 scientific cooperation is being implemented also within the framework of state-sponsored bilateral grant projects organized jointly by the State Committee of Sciences of the Ministry of Education and Science of the Republic of Armenia and the Russian Humanitarian Scientific Foundation and the Russian Foundation for Basic Research under the Government of the Russian Federation. The paper considers four competitions carried out within the framework of the above grant programs. The study is based on the Armenian, Russian and international databases to evaluate bibliometric indicators - Web of Science (WoS), Russian Index of Scientific Citation (RSCI) and Armenian Index of Scientific Citation (ASCI). The study period is 1991-2015. Due to differences in access to the above-mentioned databases, the time frame of the information used differs: publications indexed in WoS were considered for 2006-2015, RSCI - 1991-2015 and ASCI - 2007-2012. Such bibliometric indicators as author's publications number, author's citations total number, the Hirsch index, journals impact factor, self-citations number, an average number of citations per a publication are used. The above bibliometric indicators, as well as ages and scientific degrees of winners and other participants, have been compared with each other. The article also analyzes the scientific journals where the results of the projects were published. In general, the paper emphasizes the high effectiveness of state grant programs in the Armenian-Russian scientific cooperation development.

Impact of Grid Nudging Parameters on Dynamical Downscaling during Summer over Chinese Mainland
Authors: Mai Xiaoping , Ma Yuanyuan , Yang Yi , Li Deqin , Qiu Xiaobin
Published: September 2017

The grid nudging technique is often used in regional climate dynamical downscaling to make the simulated large-scale fields consistent with the driving fields. In this study, we focused on two specific questions about grid nudging: (1) which nudged variable had a larger impact on the downscaling results and (2) what was the “optimal” grid nudging strategy for each nudged variable to achieve better downscaling result during summer over the Chinese mainland. To solve this queries, 41 3-month long simulations for the summer of 2009 and 2010 were performed using the Weather Research and Forecasting model (WRF) to downscale National Centers for Environmental Prediction (NCEP) Final Operational Global Analysis (FNL) data to a 30-km horizontal resolution. The results showed that nudging horizontal wind or temperature had significant influence on the simulation of almost all conventional meteorological elements; nudging water vapor mainly affected the precipitation, humidity, and 500 hPa temperature. Moreover, the optimum nudging scheme varied with simulated regions and layers. As a whole, the optimal nudging time was one hour or three hours for nudging wind, three hours for nudging temperature, and one hour for nudging water vapor. The optimal nudged level was above the planetary boundary layer for almost every nudged variable.
Bivariate Kumaraswamy Models via Modified Symmetric FGM Copulas: Properties and Applications in Insurance Modeling
Authors: Ghosh Indranil
Published: September 2017

A copula is a useful tool for constructing bivariate and/or multivariate distributions. In this article, we consider a new modified class of (Farlie-Gumbel-Morgenstern) FGM bivariate copula for constructing several dierent bivariate Kumaraswamy type copulas and discuss their structural properties, including dependence structures. It is established that construction of bivariate distributions by this method allows for greater flexibility in the values of Spearman's correlation coefficient rho, and Kendall's tau . For illustrative purposes, one representative data set is utilized to exhibit the applicability of these proposed bivariate copula models.

In previous work (Z. Angew. Math. Phys. 68(2), 2017), Apalara considered a one dimensional thermoelastic laminated beam under Cattaneo’s law of heat conduction and proved the exponential and polynomial decay results depend on the stability number χT . In this paper, we continue to study the same system and show that the solution of the concerned system lacks of exponential decay result in the case χT ≠ 0 which solves the open problem proposed by Apalara (Z. Angew. Math. Phys. 68(2), 2017).
Lp16-PSP, A Member of YjgF/YER057c/UK114 Protein Family Induces Apoptosis and p21WAF1/CIP1 Mediated G1 Cell Cycle Arrest in Human Acute Promyelocytic Leukemia (APL) HL-60 Cells

Published: September 2017

Lp16-PSP from Lentinula edodes strain C91-3 has been reported previously in our laboratory to have selective cytotoxic activity against a panel of human cell lines. Herein, we have used several parameters in order to characterize the Lp16-PSP-induced cell death using HL-60 as model cancer. The results of phase contrast microscopy, nuclear examination, DNA fragmentation detection and flow cytometry revealed that high doses of Lp16-PSP resulted in the induction of apoptosis in HL-60 cells. The colorimetric assay showed the activation of caspase-8, -9 and -3 cascade highlighting the involvement of Fas/FasL-related pathway. Whereas, western blot revealed the cleavage of caspase-3, increased expression of Bax, the release of cytochrome c and decreased expression of Bcl-2 in a dose-dependent manner, suggesting the intrinsic pathway might be involved in Lp16-PSP-induced apoptosis either. Low doses of Lp16-PSP resulted in the anchorage-independent growth inhibition, induction of G1 phase arrest accompanied by the increased expression of p21WAF1/CIP1 along with the decreased expression of cyclin D, E, and cdk6. Our findings suggest that induction of apoptosis and p21WAF1/CIP1 mediated G1 arrest might be one of the mechanisms of the action of Lp16-PSP, however, further investigations on multiple leukemia cell lines and in vivo models are of ultimate need.
Compton Scattering of a Twisted Light
Authors: Nairat Mazen , Voelz David
Published: September 2017

The variation of photonic orbital angular momentum at Compton scattering is characterized. We determine scattering matrix of a twisted light based on the fundamental conservation of orbital angular momenta. Numerical values for two different twisted light modes: Laguerre Gaussian and Bessel Gaussian, are generated and illustrated. Our analysis indicate that states of photonic orbital angular momentum are highly changeable at wide angle scattering but more consistent at small angle scattering.

Published: September 2017

THz time-domain spectroscopy in transmission mode was applied to study dry and wet drawing inks. In specific, cochineal-, indigo- and iron-gall based inks have been investigated; some prepared following ancient recipes and others by using synthetic materials. The THz investigations have been realized on both pellet samples, made by dried inks blended with polyethylene powder, and layered inks, made by liquid deposition on polyethylene pellicles. We implemented an improved THz spectroscopic technique that enabled the measurement of the material optical parameters and thicknesses of the layered ink samples on absolute scale. This experimental investigation shows that the THz techniques have the potentiality to recognize drawing inks by their spectroscopic features.

Authors: Lo Brutto Mauro , Dardanelli Gino
Published: September 2017

Vision metrology and computer vision can be successfully used for archaeological heritage 3D reconstruction in very high precision 3D measurement projects. Of those archaeological objects requiring very accurate measurements (<1 mm), ancient mosaics comprise some of the most important. The aim of this paper is to assess the photogrammetric/computer vision approach in a vision metrology context as part of a 3D mosaics survey. In order to evaluate the optimal photogrammetric/computer vision workflow in this work, three different surveys were performed on three mosaics of different sizes and locations. Two of these are stored at the Antonino Salinas Regional Archaeological Museum in Palermo (Italy) and the other is located at the Baglio Anselmi Regional Archaeological Museum in Marsala (Italy). The mosaics survey was undertaken in order to obtain a very detailed 3D model and a full-scale ortho-image (scale 1:1), which would be useful for documentation and restoration processes. The research involved an evaluation of the potential and the related issues of the photogrammetric/computer vision approach for 3D mosaic documentation, particularly regarding the issue of camera calibration.
A procedure for point clouds matching from range data and image-based systems
Authors: Angelini Andrea , Portarena Damiano
Published: September 2017

Most of the survey techniques used in archaeology and architecture are focused on range-data (laser scanning) and image-based systems (digital photogrammetry). The paper aims to highlight a different methodological approach in the acquisition and processing procedures of the numerical data. The proposed methodology suggests an alternative way to match point clouds from laser scanner and image-based systems, exploiting the properties of the ICP algorithms. Some tests were performed at different scale in order to achieve the suitable procedure, evidencing the differences with the classic employed methods. The figures show this comparison and the making of the new procedure. The results are very interesting and concerned the merging of the numerical models from different sources. The correct position of the points in space aids the next step of the surface reconstruction (meshing process) and the final 2D representation.

Published: September 2017

The MCX beamline at the synchrotron Elettra is the general purpose diffraction beamline that is well suited for non-destructive and innovative X-ray diffraction (XRD) experiments in the field of cultural heritage. The experimental station houses a large number of instruments facilitating a range of different types of analysis. Recently, a comprehensive study of the alteration products in grisaille paints was performed at the beamline. This type of analysis is very important to understand the complex processes involved in the deterioration of this type of glass decoration. An exhaustive characterization of these products and so a full understanding of the mechanism of their formation may lead to the development of new protective materials for conservation and restoration. XRD experiments at the MCX beamline allowed us to recognize the alteration products on the grisailles surface and to propose a mechanism for the formation of alteration patina. Here we present the beamline, its instrumentation and its capabilities by showing an example of the study on grisaille paints. 
Streptococcus pneumoniae Osteomyelitis in a 25-Year-Old Man as the Initial Presentation of Multiple Myeloma
Authors: Webber Tracy , Lawlor Michael , Balach Tessa
Published: September 2017

Case:

We report the case of a 25-year-old man with femoralStreptococcus pneumoniaepyomyositis as well as hypercalcemia, mild anemia, and elevated inflammatory markers; he subsequently was diagnosed with immunoglobulin G (IgG) kappa multiple myeloma.

Conclusion:

Multiple myeloma most commonly affects patients who are >60 years of age, and causes clinical symptoms from anemia, lytic bone lesions, hypercalcemia, and renal failure. These findings and a monoclonal protein spike serve as initial diagnostic and treatment criteria. Multiple myeloma is associated with susceptibility to bacterial infections, especially encapsulated organisms; however, this is rarely the initial presentation. Additionally, it is unusual for myeloma to be diagnosed in a young person (<40 years of age).
Nonunion of a Nondisplaced Radial Neck Fracture
Authors: Coury John G. , Lum Zachary C. , Trzeciak Marc A.
Published: September 2017

Case:

We describe the case of a 66-year-old man who sustained a nondisplaced radial neck fracture and subsequently developed a symptomatic nonunion. After a period of unsuccessful conservative treatment, a radial head resection was performed.

Conclusion:

Radial neck fractures, unlike their radial head counterparts, have a low rate of nonunion. Our patient’s only positive risk factor was age, but he developed a nonunion. At the 2-year follow-up after excision of the radial head, there was a lack of proximal migration of the radius during axial loading, demonstrating a positive outcome without the need for replacement of the radial head.
Arthroscopic Repair of Recurrent Posterior Shoulder Subluxation After Total Shoulder Arthroplasty
Authors: Grieshaber-Bouyer Ricardo , Gerber Christian
Published: September 2017

Case:

A 53-year-old man presented with osteoarthritis (Walch biconcave [B2] glenoid retroversion, 22°; glenohumeral subluxation index, 65%) and a partial rupture of the supraspinatus tendon in the left shoulder. Following anatomic total joint replacement, he developed disabling recurrent posterior subluxation despite a stable prosthesis and a correctly centered glenoid head, as observed with postoperative radiography and computed tomography. In order to avoid bone loss and the complications associated with revision arthroplasty, we performed arthroscopic reefing of the posterior capsule as an experimental minimally invasive treatment. The reduction in capsular volume successfully stabilized the shoulder for approximately 9 years; thereafter, the recurrence of instability ultimately required the conversion to a reverse prosthesis.

Conclusion:

Arthroscopic capsular reefing proved to be an effective treatment for posterior shoulder subluxations after total shoulder arthroplasty, and can be considered to avoid revision arthroplasty in young patients with a stable and correctly centered prosthesis.

Cattle prices in Nusa Tenggara Barat tend to change in short time. It is difficult for farmers to predict price in the future. Price changes could affect farmers income. Therefore we need a method by which farmers could predict the price in order to make production decision. The purpose of this study was to predict of price based on the average price level for one year. This study used secondary data of cattle prices monthly, patterns of changes measured by index, then performed statistical analysis. The results of this study shows that the forecasting method used is only relevant to the pattern of price changes with a relatively similar pattern in a specified period. Price changes caused by external factors will have different pattern and causes greater deviation, so it can not be used to predict the price of cattles in NTB.

Yield components of rice are characteristics that can contribute to crop productivity levels. Grain weight per panicle produced from primary, secondary, tertiary and quarter tiller are important yield components. Information on grain weight profile may be used as the basis for improving rice cultivation techniques. Therefore, profile of the filled and empty grain weight from each type of rice panicle need to be evaluated. Evaluation of the traits was done by conducting experiment in glass house in 2013 under randomized block design, 3 replications with 1 plant per pot. Seed weight of filled and empty grain of primary, secondary, tertiary and quarter of rice panicles were observed. Thirty genotypes of rice were grouped by 8 variables of filled and empty grain weight through cluster analysis, and the profile response of filled and empty grain weight was analyzed by profile analysis of multiple variables. Profile of grain weight per cluster showed that there was no cluster with high filled grain weight and low empty grain weight for all types of panicle. Among the clusters, there were genotypes with high filled grain weight and moderate empty grain weight from each type of panicles, and they could be considered as materials in rice breeding programs.

Changes in the frequency and severity of extreme climate events and in the variability of weather patterns will have significant consequences for stability of agricultural system. Research objectives were to a) analyze the Impact of Climate Change on Food Crops in Dryland b) develop a software prototype analysis of the impact of climate change on food production, especially upland rice and maize on dry land; c) create a simulation with multiple scenarios of the impact of climate change on dry land. The study was conducted in South Sulawesi, West Nusatenggara and East Nusatenggara.The activities were carried out by projecting precipitation using scenarios: a) SRESA2 (Scenarios of climate change by assuming economic growth is lower and population growth remains high so the rate of greenhouse gas emissions increased, b) SRESB1 (scenario of climate change by assuming mitigation efforts through expanding efficient use of energy and technology improvements so that the emission levels are lower) and making projections of production of upland rice and maize using Decission Support System for Agrotechnology Transfer (DSSAT) as resource information in the preparation of prototype software information Systems Climate Change Impacts on Crop Production (SIDaPi TaPa). The system was built based on the analysis simulation model projections of production output DSSAT. Based on SRES scenarios A2, the decline in rainfall increased until 2050 in several districts, in South Sulawesi, West Nusatenggara and East Nusatenggara.Treatment of adaptation through SRESB1 scenarios could be effective to anticipate a decrease in rainfall in some regions, either in 2025 or 2050. In general, the region experiencing a decrease in rainfall will also decrease in production of both upland rice and maize production. The decline in upland rice production by SRESA2 scenario until 2050 was between 20-25%, and by a scenario adaptation SRESB1 the decline in production could be minimized to only between 7 -10%.The decline in maize production in the plot until 2050 by SRESA2 was between 9-15%, using scenarios to reduce production SRESB1 was only 5-8%. SIDAPI TAPA is a software analysis of the impact of climate change on food production, especially upland rice and maize on dry land in South Sulawesi, West Nusatenggara and East Nusatenggara.

Land conversion causes competition in land use, and thus it is necessary to select leading commodities based on agro ecological zoning (AEZ). This study aimed to determine the leading commodities of food crops in Bantul Regency agro ecological zone. This study was conducted on March 2015. The data used was time series data of food crops harvested between 2008-2012 and agricultural commodities zone maps year 2013 based on AEZ with scale 1:50.000 obtained from the Statistics of Indonesia, Agriculture and Forestry Office, and AIAT. Commodities with comparative advantages were analysed by Location Quotient (LQ) while commodities with competitive advantages were analysed by Shift Share Analysis (SSA). Leading food crops commodities were determined through an overlay process using the ArcGIS software covering analysis results of LQ, SSA and agricultural commodities zone maps based on AEZ with scale 1:50.000. The result showed that the wetland paddy is a leading commodity in the study area. Based on comparative and competitive advantages, and compatibility with agricultural commodities zone based on AEZ, wetland paddy is the most leading commodity compared to corn, soybeans and peanuts. It is because of the distribution of this commodity in 10 districts (Sanden, Kretek, Pundong, Bambanglipuro, Pandak, Bantul, Jetis, Banguntapan, Kasihan, and Sedayu) with total area of 11,667 ha or 39.4% of agricultural land in Bantul Regency

This study aimed to determine the similarity of the characteristics of each type of organic matter in suppressing the solubility of iron in soil and absorption in plants. This research was conducted in two stages. The first stage was conducted in the greenhouse to study the effect of organic matter to iron solubility in acidic sulphate soil. The research used a factorial design with 1 control and 3 replications. The first factor was type of organic matter used, B1 = rice straw; B2 = weeds; B3 = Combination of 50% rice straw and 50% weeds. The second factor was the incubation period of organic matter I1 = 2 weeks, I2 = 4 weeks, I3 = 8 weeks, and I4 = 12 weeks. The second stage was analyzing the profiles of the type of organic matter in order to evaluate the similarity of the characteristics of each type of organic matter. Based on the profile alignment, it was found that the three types of organic matter were not aligned. The types of organic matter had different roles in suppressing the solubility of iron in soil and its absorption in plants. There is a need to do a comparative analysis with Tukey method to the three types of organic matter.

In August, Mexico’s National Hydrocarbons Commission delayed the date of its next deepwater auction by a month to January 2018 to give companies more time to study the acreage on offer. Although postponing bid rounds is usually taken as a sign of lack of interest by private firms, the opposite is true in Mexico. Discoveries announced over the past few months have validated Mexico’s historic energy reform effort and may propel the oil industry there to reverse years of decline.

In a sector hampered by the downturn in oil prices, Mexico’s offshore has emerged as a bright spot. In July, US independent Talos Energy, Sierra Oil and Gas of Mexico, and Premier Oil of the UK announced one of the largest shallow-water finds of the past 20 years. The block, located off the coast of Tabasco state, holds an estimated 1.4 billion to 2.0 billion bbl of oil. The find, which came with Talos’ first exploration well, was the first since Mexico began auctioning off onshore and offshore properties in 2013. The block found up to 650 ft of oil-bearing reservoir of light crude around 28–30 °API. That same month, Italian major Eni announced the discovery of the shallowwater Amoca field in the bay of Campeche, which it said holds 1.3 billion BOE, of which 90% is oil. It is fast-tracking the development with hopes to produce from 30,000 to 50,000 B/D of 25–27 °API crude in early 2019. Consultancy PIRA Energy expects the discoveries to add up to 200,000 B/D of crude production, and believes they are economic at a $50/bbl oil price, but not for at least another decade.

Although deepwater and perhaps unconventional reserves hold the most promise for reviving Mexico’s oil sector, the country does not have a lot of time. Years of blocking the private sector out and underfunding the state oil company Pemex have taken their toll. The country’s oil and gas output is down 40% from its peak; oil production is 2.0 million B/D compared with its peak of 3.4 million B/D in 2004. That led the government to finally open the entire oil and gas sector to private money, but the reform launch could not have come at a worse time. Oil prices soon lost more than half their value, severely curtailing companies’ exploration budgets.

But the discoveries of Talos and Eni have breathed new life into Mexico’s upstream and attracted the interest of independents and supermajors. That is in contrast to the early bid rounds, which attracted only light participation. To date, seven auctions have been held—three covering onshore, three for shallow offshore, and one for deep water. Pemex has also negotiated farmout agreements with private firms. Another three are scheduled for next year. The key will be interest in the January auction. Thirty deepwater oil and gas blocks will be up for bid in areas thought to be potentially lucrative. Mexico’s deep water has been off limits to private firms and barely explored by Pemex. If resources there are anything like those found in the neighboring US Gulf of Mexico, the country’s upstream sector may become one of the globe’s offshore bright spots.
Technology Update: Tool Enables Complete Cased-Hole Formation Evaluation, Reservoir Saturation Modeling
Authors: Grover Rahul

Technology Update

For more than 40 years, the industry has used pulsed neutron logging to determine hydrocarbon and water saturations behind casing for reservoir management. Multiphase saturation measurements over time are useful for tracking reservoir depletion, planning workover and enhanced recovery strategies, and diagnosing production problems such as water influx and injection fluid breakthrough. Cased-hole logs also serve as a contingency when openhole logs cannot be run or are not considered for reservoir characterization.

Although the cased-hole measurement suite has been greatly improved over many tool generations, the intrinsic physical measurements remained unchanged, which meant that operators could not obtain a complete picture of the rock and fluids behind casing. Input from openhole logs was required from a porosity or bulk density measurement for combination with the neutron porosity. Absent this input, primary formation evaluation in cased wellbores can be ambiguous. An additional challenge with cased-hole logging is correctly compensating for the effects of borehole fluids and the presence of completion hardware.

Next-Generation Logs

To meet the need for accurate surveillance in cased holes, Schlumberger recently introduced the Pulsar multifunction spectroscopy system. The system builds on innovative technologies originated by the company to provide the first complete cased-hole formation evaluation and reservoir saturation monitoring capability with openhole-equivalent measurements.

This next generation in pulsed neutron logging integrates multiple detectors and a high-output pulsed neutron generator (PNG) to significantly improve measurement precision, data acquisition accuracy, and logging speed. The measurements are complemented by powerful algorithms that compensate for variation in the borehole fluids and completion in delivering robust, representative answers in complex conditions.

The PNG and four detectors are housed in a 1.72-in.-outside-diameter (OD) tool that is designed for through-tubing access and logging through most completion restrictions.

The detector adjacent to the PNG is the compact neutron monitor, which is primarily sensitive to fast neutrons to provide accurate and precise output measurement. There are three scintillation gamma-ray detectors for near, far, and deep detection. The near and far detectors use cerium-doped lanthanum bromide (LaBr3:Ce) scintillators, and the deep detector, farthest spaced from the PNG, has an yttrium aluminum  perovskite scintillator.

The three gamma-ray detectors are coupled to high-temperature-rated photomultiplier tubes, and their pulses are counted with specialized electronics matched to the high rate and resolution of the LaBr3:Ce scintillators.
Shale EOR Works, But Will It Make a Difference?

When EOG Resources disclosed that it had found a way to get from 30 to 70% more oil from Eagle Ford shale wells, it set off a race among competitors looking for a low-cost way to add reserves by injecting natural gas.

It has been little noticed because few companies have said anything publicly about it. But university researchers and service companies are seeing widespread interest from companies that are trying to figure out how EOG uses gas injection to increase production and whether those gains can be sustained long enough to add reserves.

Research interest in gas injection enhanced oil recovery (EOR) persuaded David Schechter, a petroleum engineering professor at Texas A&M University, to equip his lab that has been used to test carbon dioxide (CO2) for EOR to safely observe how natural gas affects reservoir rock. “Basically everyone with a substantial acreage position is working on unconventional oil EOR now,” said Schechter.

“This is the name of the game. Everybody is talking about EOR and pumping money into trials of EOR,” said Deepak Devegowda, an associate engineering professor at the University of Oklahoma.

The question facing EOG and its competitors is, can they take a method that improves results from some of its best wells, and use it on a far larger scale to increase overall recoveries in unconventional formations where more than 90% of the resource is left behind.

Companies would like to understand and simulate it and, most importantly, they are looking for clues on how EOG did it. “A whole bunch of folks are watching what other people are doing,” Devegowda said.

Companies and researchers are using statistical analysis to determine patterns in production data filed with the Texas Railroad Commission to try to figure out how EOG is using natural gas injection.

Among those looking is Todd Hoffman, an associate professor from Montana State, who was initially skeptical of EOG’s claims. After studying the data, Hoffman said that EOG clearly is “seeing huge increases in added oil production.” He is now working on a paper based on the disclosures.

As for how he figured out which of EOG’s more than 7,000 Eagle Ford wells to study, he said, “I really had to dig around to find it. I talked to a number of companies planning pilots, doing pilots, in the planning stage, trying to do the same thing,” he said.
