Optical design using image distortion for orthorectification
Authors: Johnson Tim P. , Sasian Jose , Cook Lacy G.
Published: May 2020

Imaging the curved Earth from above typically results in a distorted image with reduced spatial resolution near the edge of the field. The effect is proportional to the field of view (FOV) and altitude. It is similar to the negative (barrel) distortion common in fish-eye lenses, but is due here to the convex object and not the optical system. Although image processing methods exist to partially correct for negative distortion, the reduced spatial resolution near the edge of the field is unrecoverable. Instead this can be corrected for optically by inducing the right amount of positive distortion into the optical design. The amount of positive distortion required to counter the negative distortion from the curved Earth is calculated as a function of FOV and altitude. An optical system with positive distortion is more challenging to design than with negative distortion as this increases the FOV in image space and requires a larger focal plane array.

Thermo-optic coefficient of B2O3 and GeO2 co-doped silica fibers

Published: May 2020

New measurements of the thermo-optic coefficients (TOCs) in ternary GeO2 and B2O3 co-doped silica core optical fibers are presented. Material additivity models are applied to the measurements to shed more light on the relative contributions by each constituent. Three of the ternary fibers studied are drawn at different temperatures, but from the same preform, providing insight into the influence of fabrication conditions. It is found that the TOC of the B2O3 constituent is somewhat less negative than previously reported and trends towards more negative values with increasing draw temperature. Two approaches are taken in determining the TOC of one of the fibers, including measuring the LP11 cutoff wavelength as a function of temperature. The latter suggests an attractive application for fiber cores with a TOC lower than the cladding: fibers whose V-number intrinsically decreases with increasing temperature. Such thermally-mode-reducing optical fibers could be of great consequence for high-energy laser applications.
Embodied nations: Masculinities, nationhood and (homo)sexual desire. From Borstal Boy (2000) to God’s Own Country (2017)
Authors: Severiche Guillermo
Published: May 2020

This article proposes a comparison between Francis Lee’s God’s Own Country (UK, 2017) and Peter Sheridan’s Borstal Boy (Ireland, 2000) to examine the role that masculinities and sexual desire play in the construction, (re)configuration and (re)affirmation of nation-ness. These films depict bodies and their sensations as being able to break down and re-shape a strict and embodied notion of nationhood strongly tied by patriarchal norms. However, they also rely on rigid representations of masculinities and do not attempt to dissolve nation-ness as a corporeal entity, but to re-shape it and re-install it as a valid form of existence. Notions by Elaine Scarry’s The Body in Pain and Jasbir Puar’s Terrorist Assemblages provide the theoretical approach to observe possible changes and continuities regarding the domestication of male bodies in twenty-first-century Irish and British cinema.

INTRODUCTION:

Antibodies to hexokinase 1 (HK1) and kelch-like 12 (KLHL12) have been identified as potential biomarkers in primary biliary cholangitis (PBC), and this study assesses changes of these antibodies over time and if they are associated with clinical outcomes.

METHODS:

Two hundred fifty-four PBC patients (93.3% female, 51 ± 12.3 years old) were tested for anti-HK1 and anti-KLHL12, antimitochondrial (AMA), anti-gp210, and anti-sp100 antibodies. One hundred sixty-nine patients were tested twice and 49 three times within 4.2 (0.8–10.0) years. Biochemistry and clinical features at diagnosis, response to therapy, events of decompensation, and liver-related death or transplantation were evaluated.

RESULTS:

Anti-HK1 and anti-KLHL2 were detected in 46.1% and 22.8% patients, respectively. AMA were positive in 93.7%, anti-sp100 in 26.4%, and anti-gp210 in 21.3% of patients. Anti-HK1 and anti-KLHL12 positivity changed over time in 13.3% and 5.5% of patients, respectively. Anti-HK1 or anti-KLHL12 were present in 37.5% of AMA-negative patients, and in 40% of AMA, anti-gp210, and anti-sp100 negative. No significant differences were observed between those with or without HK1 and KLHL12 antibodies, but transplant-free survival and time to liver decompensation were significantly lower in patients anti-HK1 positive (P = 0.039; P = 0.04) and in those anti-sp100 positive (P = 0.01; P = 0.007). No changes in survival and events of liver decompensation were observed according to the positivity of AMA, anti-KLHL12, or anti-gp210 antibodies.

DISCUSSION:

HK1 and KLHL12 antibodies are present in 40% of PBC patients who are seronegative by the conventional PBC-specific antibodies. The novel antibodies remain rather steady during the course of the disease, and HK1 antibodies are associated with unfavourable outcomes.

This study investigated the influence of energy supplementation with or without the addition of lipids on microbial production, microbial synthesis efficiency and nitrogen balance. Eight fistulated steers were used with accessible rumens and kept in individual stalls. Their diets consisted of corn silage; corn silage + concentrate; corn silage + concentrate with addition of lipids in the form of soybean oil; and corn silage + concentrate with addition of lipids in the form of soybean grains. Estimates of microbial protein synthesis were obtained based on the urinary excretion of purine derivatives. The concentrations of ammonia in the rumen were determined immediately at 2, 4, 6 and 8 hours after feeding. The diets with concentrate increased (P<0.05) the microbial protein synthesis and the efficiency of the synthesis and nitrogen balance without a difference between the lipid sources (P>0.05). Concentrated diets presented higher concentrations of urea nitrogen in the serum and urinary urea excretion (P<0.05), but there was no difference between the lipid sources (P>0.05). Energy supplementation, with or without lipid addition, can be used as a strategy to increase the synthesis of the microbial protein in the cattle fed corn silage.

The aim of research was to evaluate the meat quality of Nellore young bulls in grazing supplemented with or without addition of lipids. Twenty–four young bulls, 301 ± 5.8 kg in body weight, were used in the experiment and randomly distributed into four groups according to treatment: only Panicum maximum cv. Mombasa grass; Mombasa grass with concentrated supplementation based on soybean meal; Mombasa grass with concentrate containing lipids from soybean oil; and Mombasa grass with concentrate containing lipids derived from soybean grains. There were no differences (P>0.05) between the treatments for temperature, pH, thawing, cooking and total losses, shear force, sarcomere length and collagen in bulls. Nellore young bulls raised in fertilized and irrigated Mombasa grass fed Mombasa grass only or supplemented with or without addition of lipids were similar regarding meat quality.

Published: May 2020

ABSTRACT
Thirty seven different colonies were isolated from decomposing logs of textile industries. From among these, a thermotolerant, grampositive, filamentous soil bacteria Streptomyces durhamensis vs15 was selected and screened for cellulase production. The strain showed clear zone formation on CMC agar plate after Gram’s iodine staining.  Streptomyces durhamensis vs15 was further confirmed for cellulase production by estimating the reducing sugars through dinitrosalicylic acid (DNS) method. The activity was enhanced by sequential mutagenesis using three mutagens of ultraviolet irradiation (UV), N methyl-N’-nitro-N-nitrosoguanidine (NTG) and Ethyl methane sulphonate (EMS). After mutagenesis, the cellulase activity of GC23 (mutant) was improved to 1.86 fold compared to the wild strain (vs15). Optimal conditions for the production of cellulase by the GC 23 strain were evaluated using Response Surface Methodology (RSM) and Artificial Neural Network (ANN). Effect of pH, temperature, duration of incubation, , and substrate concentration on cellulase production were evaluated. Optimal conditions for the production of cellulase enzyme using Carboxy Methyl Cellulase as a substrate are 55 oC of temperature, pH of 5.0 and incubation for 40 h. The cellulase activity of the mutant Streptomyces durhamensis GC23 was further optimised to 2 fold of the activity of the wild type by RSM and ANN.

Published: May 2020

Studies on the adaptability and stability are fundamental for plant breeding as they are an alternative to reduce the effects of genotypes x environments interaction (GxE). Moreover, they help identify cultivars with predictable behavior, which are responsive to environmental improvements, subsidizing cultivar recommendation. This study aimed to investigate the genotypes x environments interaction in cotton genotypes grown in the Brazilian Cerrado and identify genotypes for favorable and unfavorable environments. During the 2013/2014 and 2014/2015 seasons, 19 competition trials were carried out with cotton in a randomized block design, with 12 treatments, and four replications. The traits cotton seed yield, fiber percentage, fiber length, and fiber strength were evaluated. Results revealed significant GxE interaction for all the fiber traits evaluated. Genotype BRS 369 RF revealed general adaptability and high predictability for the fiber traits evaluated.

West Indian cherry stands out among the fruits cultivated for the pharmacological and alimentary importance, but its quality can be affected by irrigation water salinity and fertilization management. In this context, this research aimed to study the effect of irrigation water of different salinities and combinations of nitrogen and potassium fertilization on the physical and physico-chemical quality of bioactive compounds in West Indian cherry fruits. The experiment was carried out in the field, using lysimeters of 60 L, in the Experimental Area of the Centro de Ciências e Tecnologia Agroalimentar (CCTA) of Universidade Federal de Campina Grande (UFCG), Pombal, PB, in a randomized block design, with treatments arranged in a 5 x 4 factorial scheme, referring to five irrigation water salinities (ECw): 0.3, 1.3, 2.3, 3.3 and 4.3 dS m-1 and four combinations (C) of doses of nitrogen (N) and potassium (K2O): C1 = 70% N + 50% K2O; C2 = 100% N + 75% K2O; C3 = 130% N + 100% K2O and C4 = 160% N + 125% K2O, of the recommended dose for West Indian cherry, with three replicates and one plant per plot consisting of a lysimeter. The cv. Flor Branca grafted on cv. Junco was used in the study. The increase in salinity of irrigation water reduced the size, weight and vitamin C content of the fruits, but, the combinations of N and K fertilization did not affect fruit shape and the content of anthocyanin, carotenoids, pH, titratable acidity, total soluble solids and fruit flavor. Fertilization combinations consisting of C1 and C2 treatments promoted the largest fruit size under irrigation with ECw of up to 1.3 dS m-1 and greater mass accumulation. Fertilization doses above C2 combinations negatively affected fruit quality.

Unaccompanied refugee minors and resilience: A phenomenological study
Authors: LEKKAI INA
Published: May 2020

Unaccompanied child migration, propelled by war, political strife and instability is an increasingly serious global problem. Refugee youth contends with numerous challenges as they adjust to living in a new country. Although their capacity for resilience is being given the deserved recognition, studies where their views are taken into account greatly outweigh in number those where the voices of young refugees directly narrate how they bounce forward in the face of an uncertain future (Walsh 2002). Resilience scholars are challenged to move beyond a narrow understanding of youth refugee resilience by conducting research on their life situations exploring their own perspectives. This article describes some of the insights gained from a phenomenological study— whose methods are particularly effective at capturing and illuminating the experiences and perceptions of individuals from their own perspectives— undertaken with unaccompanied minors living in Germany. The narrative approach used to explicate their narratives highlights seven major coping strategies: (1) Treasuring personal identity, (2) Maintaining cultural identity, (3) Networks of support and social negotiations, (4) Nurturing the need to belong, (5) Embracing a positive outlook, (6) Perceived self-efficacy and personal characteristics, (7) Adopting a growth mindset & self-enhancement expectations. The empirical data of this research show that URMs are active agents in choosing meaningful pathways to resilience and purposefully navigate through the numerous challenges in their lives.
Bioprocess Optimization of L-Lysine Production by Using RSM and Artificial Neural Networks from Corynebacterium glutamicum ATCC13032
Authors: Bhushanam Vanasi , Malothu Ramesh
Published: May 2020

L-Lysine is one of the important amino acid required for humans and animals. It has a high commercial market. Large scale production of this amino acid is essential to meet the commercial demands. Typically, L-lysine is produced by batch fermentation. In the present study, the important process, as well as nutrient parameters such as glucose concentration (g/L), rpm, incubation temperature (°C), pH and incubation time for L-lysine production by Corynebacterium glutamicum ATCC13032, were optimized by a combined approach of response surface methodology (RSM) with artificial neural network (ANN) method. Initially, 32 runs face central composite design was employed. In the first step, the data was analyzed by the RSM and the optimum conditions for L-lysine production were determined. In the second step, the same data was used to train the neural network. A feed-forward neural network with error backpropagation was used. The best network was obtained by optimizing the no of neurons in the hidden layer. From the best network, the optimized weights and predicted responses were used to optimize the conditions of the selected parameters by genetic algorithm (GA). Overall with the combination of RSM-ANN-GA onefold of L-lysine production from Corynebacterium glutamicum ATCC 13032 was improved.

COVID-19 has awakened the country to a heightened state of daily, ongoing readiness for pandemic risk. Following the 9/11 terrorist attacks, the U.S. Government released a color-coded alert system to inform the public and support appropriate response, but the system was of little utility to most people. In the context of pandemic, where significant modifications to daily life are required and which change with local and regional transmission risk, the time for a color-coded alert system may have finally come

Fungi have crucial roles in ecosystems, and are important associates for many organisms. They are adapted to a wide variety of habitats, however their global distribution and diversity remains poorly documented. The exponential growth of DNA barcode information retrieved from the environment is assisting considerably the traditional ways for unraveling fungal diversity and detection. The raw DNA data in association to environmental descriptors of metabarcoding studies are made available in public sequence read archives. While this is potentially a valuable source of information for the investigation of Fungi across diverse environmental conditions, the annotation used to describe environment is heterogenous. Moreover, a uniform processing pipeline still needs to be applied to the available raw DNA data. Hence, a comprehensive framework to analyses these data in a large context is still lacking. We introduce the MycoDiversity DataBase, a database which includes public fungal metabarcoding data of environmental samples for the study of biodiversity patterns of Fungi. The framework we propose will contribute to our understanding of fungal biodiversity and aims to become a valuable source for large-scale analyses of patterns in space and time, in addition to assisting evolutionary and ecological research on Fungi.
Topological edge and corner states in a two-dimensional photonic Su-Schrieffer-Heeger lattice
Authors: Kim Minkyung , Rho Junsuk
Published: May 2020

Implementation of topology on photonics has opened new functionalities of photonic systems such as topologically protected boundary modes. We theoretically present polarization-dependent topological properties in a 2D Su-Schrieffer-Heeger lattice by using a metallic nanoparticle array and considering the polarization degree of freedom. We demonstrate that when eigenmodes are polarized parallel to the plane of the 2D lattice, it supports longitudinal edge modes that are isolated from the bulk states and transverse edge modes that are overlapped with the bulk states. Also, the in-plane polarized modes support a second-order topological phase under an open boundary condition by breaking the four-fold rotational symmetry. This work will offer polarization-based multifunctionality in compact photonic systems that have topological features.

Published: May 2020

The strategy to improve the photocatalytic removal efficiencies towards organic pollutants is still a challenge for the novel Sillen–Aurivillius perovskite type Bi4NbO8Cl. Herein, we report carbon-supported TiO2/Bi4NbO8Cl (C-TiO2/Bi4NbO8Cl) heterostructures with enhanced charge separation efficiency, which were fabricated via molten-salt flux process. The carbon-supported TiO2 particles were derived from MXene Ti3C2 precursors, and attached on plate-like Bi4NbO8Cl, acting as electron-traps to achieve supressed recombination of photo-induced charges. The improved charge separation confers C-TiO2/Bi4NbO8Cl heterostructures superior photocatalytic performance with 53% higher than pristine Bi4NbO8Cl, towards rhodamine B removal with the help of photo-induced holes. Moreover, the C-TiO2/Bi4NbO8Cl heterostructures can be expanded to deal with other water contaminants, such as methyl orange, ciprofloxacin and 2,4-dichlorophenol with 44, 25 and 13% promotion, respectively, and thus the study offers a series of efficient photocatalysts for water purification.
The “Japanese Turn” in Fine Dining in the United States, 1980–2020
Authors: Yamashita Samuel H.
Published: May 2020

In the 1970s, Japanese cooks began to appear in the kitchens of nouvelle cuisine chefs in France for further training, with scores more arriving in the next decades. Paul Bocuse, Alain Chapel, Joël Robuchon, and other leading French chefs started visiting Japan to teach, cook, and sample Japanese cuisine, and ten of them eventually opened restaurants there. In the 1980s and 1990s, these chefs' frequent visits to Japan and the steady flow of Japanese stagiaires to French restaurants in Europe and the United States encouraged a series of changes that I am calling the “Japanese turn,” which found chefs at fine-dining establishments in Los Angeles, New York City, and later the San Francisco Bay Area using an ever-widening array of Japanese ingredients, employing Japanese culinary techniques, and adding Japanese dishes to their menus. By the second decade of the twenty-first century, the wide acceptance of not only Japanese ingredients and techniques but also concepts like umami (savory tastiness) and shun (seasonality) suggest that Japanese cuisine is now well known to many American chefs.
Competitive Coffee Making and the Crafting of the Ideal Barista
Authors: Parrish Sabine
Published: May 2020

Despite widespread attention to issues of gender and economic exploitation at coffee's agricultural origins, works within coffee scholarship systematically overlook the workers at the final stage of production: baristas, the coffee shop employees who prepare and serve beverages. This article draws from data collected from over four hundred female American specialty coffee baristas to examine how their gender impacts their experiences at coffee competitions. I argue that barista competitions exist in order to legitimize the barista as a type of skilled laborer, but that these attempts rest on highly gendered understandings of skill, professionalism, and performance. Barista competitions attempt to present a unified industry face, but gender remains a salient issue through its unequal presence that renders female baristas as distinct and different from the ideal barista, who is assumed to be male. The conclusions drawn from this case study have broad significance for our understandings of gender and precariousness in the food industry, and the relationship between, and negotiation of, skill and perceived value. The rarefied world of specialty coffee competition magnifies and illuminates extant workplace issues regarding gender, which are characteristic of many forms of low-wage service labor in the United States.
Homicide by Police
Authors: Stephens Elizabeth
Published: May 2020

Research on survivors of homicide has focused on various circumstances and the impact of homicide on family members and strangers. However, research regarding the survivors of individuals killed by police remains difficult to find. This particular kind of public, traumatic death of a loved one imposes unique and traumatic grief for the survivors. Per the 2014 FBI Uniform Crime Report, my family and I were one of an estimated 461 families affected by the death of a loved one due to police homicide in 2013. This estimate is low, however, because only thirty-three states voluntarily report such information, and law enforcement agencies are not required to report civilian deaths by police homicide. This narrative explores the impact of homicide by police on me as a survivor and mother as I coped with the death and trauma of my adult son’s death by police. Using short episodes of interactions, I analyze my experience and ongoing grief.

Se presenta la caracterización del ambiente acuático, el ecosistema ribereño y las comunidades de macroinvertebrados en siete cuencas del flanco oeste del Parque Nacional Yanachaga Chemillén (PNYCh). Se aplicó el protocolo CERA que incluye el Índice Biótico Andino (IBA), el Índice de Hábitat Fluvial (IHF), el Índice de quebrada Andina (Qbr-And) y la combinación de los tres índices para determinar el Índice de Estado Ecológico de Ríos Andinos (ECOSTRIAND) en cada punto de muestreo. Asimismo, se estimaron los índices FBI y BMWP-Col para comparar la calidad de agua. Los muestreos se realizaron en las siete cuencas, entre los 1800 y los 2500 m de altitud, en la parte alta dentro del PNYCh, y en las cuencas media y baja, ambas en la zona de amortiguamiento del PNYCh. En las cuencas evaluadas se colectaron 179 taxa, 66 familias y 14 órdenes. Dentro del PNYCh los valores de IHF y Qbr-And fueron óptimos y en general fueron disminuyendo en calidad al alejarse del PNYCh. El IBA fue muy bueno en todas las cuencas y en todos los puntos de muestreo. Sin embargo, al combinar los 3 índices se observó una disminución del estado ecológico (ECOSTRIAND) de Muy bueno a Bueno y Regular. Los resultados finales muestran que el índice de estado ecológico disminuye al alejarse del PNYCh y esto coincide con un mayor disturbio de los bosques ribereños. Por último, se discute la protección legal de este tipo de ecosistemas ribereños en varios países de América y específicamente en Perú.

They were also able to stay in contact with research authors, asking additional questionsand giving remarks.Results: During the study, a total of 1349 questionnaires were collected, out of which1276 met inclusion criteria and were enrolled in the study. 66.1% of the respondent groupwere females and 33.9% males. The mean age was 28.3 ± 9.5 years (range: 14-75). Themean PI20 score was 49.6 ± 18 (range: 20-99). In 11.8% of respondents PI20 result indicatedself-reported mild, in 8.3% moderate and in 3.9% severe DP. The mean CFMT totalscore was 58.1 (median: 59, range: 26-72) and mean GFMT score was 33.9 (median: 34,range: 18-40). According to the cutoff values from original papers, 81 (6.3%) of respondentsscored below threshold in CFMT, 27 (2.4%) in GFMT. Out of 50 respondents whoself-reported symptoms indicating severe DP, only 15 (30%) scored below the cutoff inCFMT and 6 (12%) in GFMT. On the contrary, 30 (3.1%) and 16 (1.4%) out of 970 respondentsreporting no problems with face recognition had total scores below the cutoff inCFMT and GFMT, respectively.Conclusions: The estimated prevalence of developmental prosopagnosia in Polishpopulation is higher than in normative data. These discrepancies may result from specifi cdemographics of participant group more than an online-character of the study. It is

important to focus on experiment design and methodology in order to maintain high quality ofcollected data. Development of country-specifi c norms and stimuli for face-recognitiontests should also be considered .
Looking at the new digital school: didactics 2.0 and school 2.0
Authors: PAOLO DI SIA
Published: May 2020

Aim. Today we have the need to develop more effective teaching methods, where thestudent is no longer just a user, but becomes an integral part of the training process by creating,selecting and processing experiences in a personal way. Digital teaching has become/isbecoming part of the school scenario along with the wealth of digital technologies and toolsthat have spread over the past decades. Today’s society has changed and even the schoolmust be able to exploit all resources that social networks make available for capturing theattention of “digital natives”.Methods. The student becomes an active constructor of knowledge, integrating it in apersonal way. We talk about “didactics 2.0”, i.e. the study and improvement of teachingactivity achievable with the use of ICT tools. To create a learning environment, we musttake into account the collaboration of several parties (teachers, experts in the fi eld, students,parents), not forgetting the complexity and multiplicity of the surrounding reality. Thislearning environment can profi tably use social networks; students show to learn better ifthey fi nd meaningful the subjects they are studying.Results. The paper illustrates tools and forms of collaboration achievable with thedigital educational school environment. Social networks are used by students to thepoint of becoming a real language for “digital natives”. When we talk about digitalculture, we want to highlight the participation and digitalisation of traditional culturalprocesses, from which the educational environment does not escape. In the “school2.0” approach there are some peculiarities leading the school system towards the newgenerations.Conclusions. The need to “digitise” the school is a current hot topic, also if in everydayreality the work to do is still a lot: non-existent or obsolete computer labs, teachers who donot consider computers as a resource. Digitised teaching can be realised according to multiplechannels that have different characteristics and purposes.

The role of orographic effects on occurrence of the heavy rainfall event over Central Vietnam in November 1999
Authors: Nhu Dang Hong , Anh Nguyen Xuan , Phong Nguyen Binh , Quang Nguyen Dang , Nguyen Hiep Van
Published: May 2020

In this study, the WRF model is used to investigate the role of Central Vietnam terrain on occurrence of the heavy rainfall event in November 1999 over Central Vietnam. Two model experiments with and without terrain were performed to examine the orographic blocking effects during the event. In the terrain experiment, the results from a three-day simulation show that the model reasonably well captures northeast monsoon circulation, tropical cyclones and the occurrence of heavy rainfall in Central Vietnam. The topography causes a high pressure anomaly intensifying northeast monsoon. When the terrain is removed, the three-day accumulated rainfall decreases approximately 75% in comparison with that in the terrain experiment. The terrain blocking and lifting effects in strong wind and moisture laden conditions combined with convergence circulation over open ocean are the main factors for occurrence of the heavy rainfall event.

An earthquake has occurred at 10:22:33 UT on 5 August 2014 in the Klerksdorp district, the North West province of South Africa. Its hypocenter is located beneath an Orkney town, where more than 10 gold mines exist. The Council for Geoscience (CGS) in South Africa reported that the magnitude and depth was ML5.5 and 4.7 km, respectively. CGS has been operating 17 surface seismic acceleration stations with 10 km interval in average, and obtained continuous acceleration seismograms through the time of the earthquake and following aftershocks. Using these seismograms, we analyzed the mainshock rupture process of this earthquake. Analyzing these seismograms, we found the ‘initial rupture’ with a Richter scale approximately 4 has occurred 0.3 sec before mainshock. Furthermore, by applying detailed aftershock distribution analysis, we found most of aftershocks occurred surrounding upper and southern part of mainshock rupture area, including initial rupture hypocenter. In order to understand detailed rupture process of this event, we surveyed for strong motion generating area (SMGA) of mainshock by applying Isochrones backprojection method (IBM) to the mainshock S wave waveforms. SMGA distribution seems to fill the vacant space of the aftershock distribution and initial rupture’s hypocenter. And we also found that a horizontal layered seismic vacancy exists between aftershocks with gold mine blastings. This fact implies mainshock rupture did not extent up to gold mine.
Determination of the constant Wo for local geoid of Vietnam and it’s systematic deviation from the global geoid
Authors: Truong Nguyen Ngoc , Nhac Tran Van
Published: May 2020

Constant Wo, defining the geoid, has important applications in the area of physical geodesy. With the development of artificial Earth satellite, constant Wo for the global geoid approximating the oceans on Earth can be calculated from an expansion of spherical harmonics - Stokes constants determined by observation of perturbations in artificial satellite’s orbits. However, the Stokes constants are limited, therefore the geoid constant Wo could not be calculated for local geoid (state geoid) from the mentioned expansion of spherical harmonics. In this paper, we present a method to determine the constant Wo for local geoid of Vietnam, using generalized Bruns formula and Neyman boundary problem. The initial data used are Faye gravity anomalies surveyed on land and sea of Southern Vietnam. The constant Wo is then used to calculate the systematic deviation of the local geoid of Vietnam from the global geoid EGM - 96.

Published: May 2020

Migration methods play an essential role in processing ground penetrating radar data. For estimating electromagnetic propagation velocity distribution, the finite - difference migration is used because of its reliable performance with high noise conditions. To optimize this migration algorithm, we propose using energy diagram as a criterion of looking for the correct velocity. If the velocity varies laterally and vertically, split step Fourier migration is used for creating a true image of subsurface structures. We applied these steps to real data in Vietnam. The results verified on field data show that migrated images with calculated velocity from energy diagram have the best quality.

Published: May 2020

In recent years, the satellite altimeter technology allows enhancing the marine investigation in many areas. Up to now, many scientific studies have attempted to improve the accuracy and resolution of altimeter-derived gravity anomalies and have produced a gravity grid with interval of 1’×1’ for most oceans all over the world. However, these gravity anomalies are not very highly accurate and have a large difference compared to shipboard gravity anomalies, especially in the coastal and islands areas. The purpose of this article is to improve the accuracy of altimeter-derived marine gravity anomalies for geological structure research in the East Vietnam Sea deep-basin and adjacent areas. The least squares collocation method is used to correct the altimeter-derived marine gravity data based on the shipboard gravity data in order to improve the accuracy of marine gravity anomalies. In this article, the altimeter-derived marine gravity anomalies are taken from Sandwell, D. T., et al., (V24.1) and the shipboard gravity anomalies are from the survey projects between Vietnam, Russia and other countries. The mean-squared error when comparing both data is about 9,358 mGal. After correcting by collocation method, the error was reduced to 3,208 mGal (for the altimeter data coinciding with shipboard track). Also, in this article, the achieved results show the efficiency and actuality of the corrected-altimeter-derived marine gravity anomalies for more detailed researches of geological structures. Especially, it is more meaningful in the remote or sparsely surveyed regions.

As an active member of the United Nations Convention on the Law of the Sea - UNCLOS, Vietnam has completed 3 Reports on the Limits of the Continental Shelf and has submitted two of them to the Commission on the Limits of the Continental Shelf - CLCS, before the deadline 13-5-2009. Those are: (1) Outer Limits of the Vietnam’s Extended Continental Shelf: North Area (VNM-N); (2) Outer Limits of the Vietnam’s Extended Continental Shelf: Middle Area (VNM-M) and (3) Vietnam - Malaysia Joint Continental Shelf Submission. The VNM-M has not yet been submitted but it was mentioned to the CLCS and will be submitted in the appropriate time.Vietnam’s submissions were highly appreciated by CLCS; although the CLCS has not yet organized a special sub-committee to look at our reports, the secretariat of CLCS has already posted the executive reports of our submissions, with our principle claims on the continental shelf, on the website of the CLCS since May 2009. This paper presents shortly the UNCLOS and its application in Vietnam case.

The calculations which determine the chemical composition of the primitive magma are simple but they show changes in the temperature and pressure states of the magma source. The method is based on the addition of the chemical composition of the Olivine to the major element composition of the eruptive rocks which follows the formula: Ci = Ci-1+ 0.1 * Ci-1Ol. In accordance with the characteristics of the study area, we have made new additions to the calculation method. The calculation results are highly accurate when tested and compared with the chemical composition of the eruptive rocks. The chemical composition of the primitive magma solution is used to calculate the temperature and pressure states in the magma source. The results show that there is a difference in temperature and pressure in the source at different tectonic positions in the study area. Accordingly, the South Central coast region and the adjacent continental shelf are divided into two main types of eruptions. The first type of volcanic eruptions occurs at locations where major faults intersect and they are located north of the study area. The second type of volcanic eruptions in the form of a single volcano is located to the south of the study area and the southeastern continental shelf, and occurs in intracontinental extension structure.
