Variable aspect ratio method in the Xu–White model for shear-wave velocity estimation

Shear-wave velocity logs are useful for various seismic interpretation applications, including bright spot analyses, amplitude-versus-offset analyses and multicomponent seismic interpretations. This paper presents a method for predicting the shear-wave velocity of argillaceous sandstone from conventional log data and experimental data, based on Gassmann's equations and the Xu–White model. This variable aspect ratio method takes into account all the influences of the matrix nature, shale content, porosity size and pore geometry, and the properties of pore fluid of argillaceous sandstone, replacing the fixed aspect ratio assumption in the conventional Xu–White model. To achieve this, we first use the Xu–White model to derive the bulk and shear modulus of dry rock in a sand–clay mixture. Secondly, we use Gassmann's equations to calculate the fluid-saturated elastic properties, including compressional and shear-wave velocities. Finally, we use the variable aspect ratio method to estimate the shear-wave velocity. The numerical results indicate that the variable aspect ratio method provides an important improvement in the application of the Xu–White model for sand–clay mixtures and allows for a variable aspect ratio log to be introduced into the Xu–White model instead of the constant aspect ratio assumption. This method shows a significant improvement in predicting velocities over the conventional Xu–White model.

Facilitating public & private security operators to mitigate terrorism scenarios against soft targets

Ensuring public spaces safety while preserving the freedom of citizens represents a challenge for European societies. Soft targets like malls, stadiums or big events continue to face a variety of evolving cyber and physical threats. To secure public spaces and other soft targets requires an integral security approach and new concepts involving all the security actors along with private operators.

APPRAISE aims to build on the latest advances in big data analysis, artificial intelligence, and advanced visualisation to create an integral security framework that will improve both the cyber/physical security and safety of public spaces by enabling a proactive, integrated, risk-based, and resilience-oriented approach. This framework will be designed to support the secured private-public collaboration and optimise the coordination of operations involving private security staff, private operators, and law enforcement agencies.

APPRAISE will offer unprecedented capabilities to predict and identify criminal and terrorist acts and enhance the operational collaboration of security actors before, during, and after an incident occurs. Social, Ethical, Legal, and Privacy observatories bringing together LEAs, private operators, technology experts, psychologists, sociologists, and society representatives will ensure full conformity of the developed tools with current EU legislation and citizens’ acceptance, preparing the ground for successful exploitation. 

The consortium consists of world-class research centres, industries, SMEs, LEAs of different types (national police, municipal police, elite tactical unit) as well as private security practitioners and operators, coordinated by a large industrial company with a leading position in the security market. 

APPRAISE will demonstrate its solutions in four complementary pilot sites: a tennis tournament in Italy, a transnational cycling tour with stages in France and Spain, an international fair in Poland, and a mall in Slovenia.
La Gestión del Conocimiento y la Tecnológica como Herramienta Investigativa para el Reconocimiento de la Responsabilidad Social y la Asociatividad en el Sector Agroindustrial del Departamento del Quindío

The development of critical knowledge requires a creative blend of traditional methods of gathering information and new research approaches. Consultation with stakeholders in investigating help to approach to their needs. It is pertinent to say that they are the main guarantors of strengthening within the community. In this article we review the traditional approaches to knowledge management and compare how communities can impact the investigative processes that are performed. There is also evidence about the contribution made by agribusiness producers of the department of Quindio to build management tool in social responsibility and association which has been prepared from non-traditional approaches to research such as technology transfer and participatory research.

Modelling and simulation of direct solar radiation for cost-effectiveness analysis of V-Trough photovoltaic devices

In the urge to make solar energy competitive enough to directly face fossil fuels, several approaches result crucial for their intended capacity to maximise the energy that can be produced with a given photovoltaic area. Low Concentration Photovoltaics (LCPV) and tracking methods can be integrated in V-Trough solar devices to increase their effective solar harvesting area through low-cost non-imaging optics. As a tool to support the design and simulation of such devices, this work proposes an analytical and numerical model that simulates the interactions of direct solar radiation with the V-Trough’s elements. The proposed model is design-oriented and was developed seeking high parameter flexibility, high geometrical detail and low computational demands. The model was experimentally validated through several simulations of V-Trough set-ups which results were compared against measurements with a testing platform. Through a non-parametric statistical analysis, the model proved to be satisfactory and highly accurate. Furthermore, the calculations regarding optical concentration performance were complemented with a cost analysis and integrated into a cost-effectiveness index. The results from this work serve as a useful modelling tool for designing and comparing alternatives of V-Trough solar devices.
Validation of a Strategy for Cancer Therapy: Delivering Aminoglycoside Drugs to Mitochondria in HeLa Cells

Mitochondria in human cancer cells have been implicated in cancer cell proliferation, invasion, metastasis, and even drug-resistance mechanisms, making them a potential target organelle for the treatment of human malignancies. Gentamicin (GM), an aminoglycoside drug (AG), is a small molecule that functions as an antibiotic and has ototoxic and nephrotoxic characteristics. Thus, the delivery of GM to mitochondria in cancer cells would be an innovative anticancer therapeutic strategy. In this study, we attempted mitochondrial delivery of GM in HeLa cells derived from a human cervical cancer. For the mitochondrial delivery, we used MITO-Porter, a liposomal nanocarrier for mitochondrial delivery via membrane fusion. We first encapsulated GM in the aqueous phase of the carrier to construct GM-MITO-Porter. Flow cytometry analysis and fluorescent microscopy observations permitted us to confirm that the GM-MITO-Porter was efficiently taken up by HeLa cells and accumulated in mitochondria, whereas naked GM was not taken up by the cells. Moreover, cell viability assays using HeLa cells showed that the GM-MITO-Porter induced strong cytotoxic effects related to mitochondrial disorder. This finding is the first report of the mitochondrial delivery of an AG to cancer cells for cancer therapeutic strategy.
Land-Based solutions for plastics in the sea

There are 5,250 billion plastic particles floating on the surface on the world's seas and oceans, equivalent to 268,940 metric tons of waste. These fragments move with the currents before washing up on beaches, islands, coral atolls or one of the five great ocean gyres. Because MP cannot be removed form oceans, proactive action regarding research on plastic alternatives and strategies to prevent plastic entering the environment should be taken promptly. Despite the research increasing, there is still a lack of suitable and validated analytical methods for detection and quantification of small micro- and nano plastics (SMNP) evidencing a huge obstacle for large-scale monitoring. There is also a lack of hazard and fate data which would allow their risk assessment. 
LABPLAS is a 48-months project whose vision is creating capacities (sampling, analysis and quantification techniques, new materials and new models) to evaluate rapidly and precisely the interactions of plastics with the environmental compartments and natural cycles leading to the development of effective mitigation and elimination measures, as well as, making management decisions. It will assess reliable identification methods for more accurate assessment of the abundance, distribution and toxicity determination of SMNP in the environment, giving the opportunity of new developments of cutting edge technologies. It will also develop practical computational tools that up-scaled should allow European agencies to map plastic-impacted hotspots.  The project will have a multi-actor approach, creating scientific knowledge with a partnership of scientists, technicians, research organizations and enterprises, working together towards the recognition at different levels (society, industry, policy) of the main issues (sources, potential biodegradability, ecotoxicology, ingestion, environmental assessment) related to the presence of plastics in ecosystems.
Modeling Government ERP Acquisition Methods Using System Dynamics

A large percentage of companies implementing ERP experience schedule and budget overruns. In the two Air Force ERP projects studied in this thesis, DoD has experienced a schedule slippage of 3-4 years and life-cycle cost estimates almost doubled in each of these projects. Given the scale and complexity of these projects, and the number of different stakeholders involved, evaluation of the delay by checking off the high-level critical success factors as per literature does no good. Misaligned incentives between stakeholders especially sponsor organization and system integrator, failure to accommodate rework in the master project plan, choosing the right contract terms, lack of in-house technical expertise, control of sponsor over project execution were some of the aspects which emerged to be important during the case study analysis; and were re-validated using the system dynamics model. The impact of the different contract models on the Critical Success Factors, depending on the level of knowledge on legacy and the completeness of requirements, has also been examined. A System Dynamics model is developed to help in evaluating Lead System Integrator v/s Project management in-house governance models. We consider factors such as the sponsor’s ability to adjust the RICE component estimations and the credibility of the contractor-staff working on the project. This thesis sets an outline for importance of governance models and delving deeper onto the process of selecting a contractor and setting incentives which help align the goals of the contractor to those of the sponsor organization.

Improving the authentic learning experience by integrating robots into the mixed-reality environment

The main aim of the modern popular teaching method of authentic learning has been to provide students with everyday-life challenges that develop knowledge and skills through problem solving in different situations. Many emerging information technologies have been used to present authentic environment in pedagogical purpose. However, there are few studies that have been discussed the sense of authenticity and characters in scene and how students interact with the characters involved in the task. We designed a system, RoboStage, with authentic scenes by using mixed-reality technology and robot to investigate the difference in learning with either physical or virtual characters and learning behaviors and performance through the system. Robots were designed to play real interactive characters in the task. The experiment of the study conducted with 36 junior high students. The results indicated that RoboStage significantly improved the sense of authenticity of the task and also positively affected learning motivation. Learning performance was conditionally affected by RoboStage.
Investigation of the flatness of rolled aluminium sheet

Abstract A lot of problems arise even recently concerning the control of flatness and profile of rolled strip in industrial circumstances. In the course of planning of the cold-rolling technology of geometrically true strip that is exempt of internal deformation stresses — i.e. flatness strip — it is necessary to take into consideration the elastic and thermal deformation of working rolls, the basic sheet-metal forming of rolls, the existing crown of basic material as well as the wearing of the rolls. A measurement method by which the shape of strip can exactly be measured is necessary for performing the control. In the present phase of my research work, a measurement device has been developed by means of which the given problem can be solved for the time being in experimental circumstances.
Evaluation of viableMycobacterium aviumsubsp.paratuberculosisin milk using peptide-mediated separation and Propidium Monoazide qPCR

The causative agent of paratuberculosis in ruminants, Mycobacterium avium subsp. paratuberculosis (MAP), although still a matter of debate, has been linked with Crohn's and other human diseases. The availability of rapid methods for assessing the viability of MAP cells in food, in particular milk, could be of great use for risk management in food safety. MAP viability is generally assessed using culture techniques that require prolonged incubation periods for the growth of MAP. To differentiate between viable and nonviable MAP cells in milk samples, this study explores the combination of two already described techniques: peptide magnetic bead separation followed by Propidium Monoazide qPCR. Using an Ordinal Multinomial Logistic Regression model to analyze the results obtained after spiking milk samples with mixtures containing different percentages of viable/dead cells, we were able to assess the probability of the viability status of MAP found in milk. This model was applied to contaminated pasteurized milk to ascertain the efficacy of heat treatment in MAP killing. The method reported herein can potentially be used for direct detection of MAP viability in milk.
Patterns and correlates of polytobacco use in the United States over a decade: NSDUH 2002–2011

Few studies have examined the patterns and correlates of polytobacco use among a large, nationally representative population over an extended period of time.This study examined 10years of data from the National Survey on Drug Use and Health (NSDUH) to establish time trends and correlates for exclusive and mixed use of cigarettes, smokeless tobacco (SLT), cigars, and pipes.Results show that rates of polytobacco use were essentially unchanged from 2002 to 2011 (8.7% to 7.4%), though some product combinations, including cigarettes and SLT, cigars and SLT, and use of more than two products have increased. In tobacco users under age 26, the proportion of polytobacco use increased, even as overall tobacco use declined. The factors associated with polytobacco use among tobacco users included sex, income, education, risk taking/seeking behaviors, and outward indicators of 'risk-liability'.Findings provide a snapshot of trends of single and polytobacco product use as well as trends in combinations of product use. Longitudinal studies are needed to examine the sequence of individual patterns of tobacco product use and to identify whether polytobacco use results in greater nicotine dependence, increased exposure to harmful and potentially harmful constituents and/or greater risk of tobacco related disease.
Accessibility to and Utilization of Healthcare Services Pre- and Post-typhoon Yolanda as Perceived by Senior Citizens in a Rural Area in the Philippines

Background: The problems of accessibility to and utilization of healthcare services are fundamental and constant issues in every country's healthcare system especially among the senior citizens. Objective: The study investigated the accessibility to and utilization of healthcare services among senior citizens in the Province of Leyte as determined by the predisposing, enabling, and need factors. Methods: The sample consisted of 496 60 years old and above senior citizens from randomly selected barangays of Districts 1 and 2 of Leyte Province. An interview schedule was designed to gather data through structured interviews. The data were analyzed using descriptive statistics to determine the level of accessibility and utilization, Point-biserial and Pearson product-moment correlation coefficient (Pearson's r) and eta correlation to check significant relationships among variables, and multiple linear regression to identify predictors of accessibility and utilization. Results: Findings revealed that sex, occupation, primary source of income, health status, medical condition, and disability had weak correlations with accessibility and utilization during pre-typhoon and post-typhoon. Lastly, medical conditions and health status were the best predictors of accessibility and utilization during pre-typhoon and post-typhoon. These findings lead to the development of a local model on the accessibility to and utilization of healthcare services that are more reflective for senior citizens in rural areas in the Philippines. Conclusion: More research is needed to replicate these results to substantiate the significance of addressing the healthcare needs of the senior citizens in rural areas.
Developmental diversity in free-living flatworms

Flatworm embryology has attracted attention since the early beginnings of comparative evolutionary biology. Considered for a long time the most basal bilaterians, the Platyhelminthes (excluding Acoelomorpha) are now robustly placed within the Spiralia. Despite having lost their relevance to explain the transition from radially to bilaterally symmetrical animals, the study of flatworm embryology is still of great importance to understand the diversification of bilaterians and of developmental mechanisms. Flatworms are acoelomate organisms generally with a simple centralized nervous system, a blind gut, and lacking a circulatory organ, a skeleton and a respiratory system other than the epidermis. Regeneration and asexual reproduction, based on a totipotent neoblast stem cell system, are broadly present among different groups of flatworms. While some more basally branching groups - such as polyclad flatworms - retain the ancestral quartet spiral cleavage pattern, most flatworms have significantly diverged from this pattern and exhibit unique strategies to specify the common adult body plan. Most free-living flatworms (i.e. Platyhelminthes excluding the parasitic Neodermata) are directly developing, whereas in polyclads, also indirect developers with an intermediate free-living larval stage and subsequent metamorphosis are found. A comparative study of developmental diversity may help understanding major questions in evolutionary biology, such as the evolution of cleavage patterns, gastrulation and axial specification, the evolution of larval types, and the diversification and specialization of organ systems. In this review, we present a thorough overview of the embryonic development of the different groups of free-living (turbellarian) platyhelminths, including the Catenulida, Macrostomorpha, Polycladida, Lecithoepitheliata, Proseriata, Bothrioplanida, Rhabdocoela, Fecampiida, Prolecithophora and Tricladida, and discuss their main features under a consensus phylogeny of the phylum.
Network of qualified services for the development of the cross-border citrus production chain

The common challenge concerns strengthening the competitiveness of MSMEs through the provision of services to support “Research and development” in the citrus fruit sector. CITRUS will support the competitiveness of MSMEs by providing services to enhance skills and know-how in the citrus fruit sector. Starting from the results achieved by the Mare di Agrumi project (Axis 1 - 1st Call), the main changes expected concern an increase in the number of target beneficiaries, with specific reference to companies interested in creative transformation processes (new processes; improvement and innovation of the processes currently in use), the reuse of waste (circular economy) and tourism enhancement linked to citrus fruits (range of products and services related to the tourism brand). The project’s main outputs are: a “CITRUS” business plan (including a co-development strategy); a CITRUS innovation hub (including a range of specialised services and the list of “experts” who will provide the services); a “CITRUS” call for ideas to select the companies that will benefit from the specialised services; CITRUS specialised services. The direct beneficiaries will be MSMEs that are already active in the citrus fruit supply chain, or that are interested in capitalising on the development opportunities that characterise it. CITRUS involves adopting an “open innovation” approach based on the implementation of co-conception, co-design and co-development processes. Given the specific features that characterise the citrus fruit sector in the regions involved, only by adopting a cross-border approach will it be possible to transform the opportunities offered by the citrus fruit supply chain into real tools to support the competitiveness of MSMEs. The innovative aspects of CITRUS are: implementation of an open innovation process; definition of a cross-border business plan; provision of cross-border services; implementation of innovative, circular economy processes.
