INFLUENCE OF AGGREGATE CHEMISTRY ON THE ADSORPTION AND DESORPTION OF ASPHALT

Asphalt-aggregate interactions were investigated by evaluating the adsorption and desorption of aged and unaged asphalts on four aggregates: limestone, greywacke, gravel, and basalt. The aggregate composition and surface chemistry had a greater effect on the adsorption and desorption characteristics of the asphalt-aggregate pair than the properties of the asphalt did. Adsorption and desorption isotherms were fitted to the Langmiur model and yielded predicted monolayer amounts, equilibrium constants for adsorption, and Gibbs free energy of adsorption. The Gibbs free energies were evaluated in terms of the principles of soil mechanics, which showed that water in the voids can be drawn to the asphalt-aggregate interface at relative humidities of 99% or above. Estimates of minimum tensile strength ratios were determined from Gibbs free energies and the extrapolated measured enthalpy values. The presence of water at the interface reduces the Gibbs free energy values between the asphalt and aggregate, thereby reducing the tensile strength and resistance to debonding fracture.
Rural Tourism Entrepreneurship as Strategy for Economic Development in Nigeria

Rural tourism entrepreneurship is a tourist industry which revolutionizes businesses and prompting economic development across the globe. It encompasses huge range activities, natural or man-made attractions, amenities and facilities, transportation, marketing and information systems. It is also an important export for 83% of the developing countries and the main export for one third of them. In 2000, developing countries recorded 142.6 million international arrivals an increase of 95% compared to the figures of 1990.However, only developing countries with effective natural and man-made tourism supporting and enhancing infrastructure have been able to develop their tourism sector and seize the attendance advantages. Rural areas of Nigeria possess some distinctive peculiarities which can be transformed into attractive tourist centers. In spite of all these, rural tourism areas are still faced with myriad problems which include poor finance inadequate awareness and education, lack of progress in developing the rural of progress in developing the rural tourism potentials inadequate legislation, insecurity, entrepreneurial inertness, over-dependent on oil among others. This paper focuses on the impact and challenges of rural tourism entrepreneurship as strategy for economic development in Nigeria. It reviews literature rural tourism, tourism entrepreneurship potentials and classifications of Nigerians tourism potential’s destinations. The paper concludes that Nigeria Government should encourage rural based tourism entrepreneurship development by addressing the challenges facing rural tourism entrepreneurship in the country.
LDL-cholesterol and coronary artery disease: where we've been, where we're going

The developed world is experiencing an epidemic of coronary artery disease (CAD). In the United States alone more than 10 million people have symptomatic CAD and approximately 1.5 million people present with new myocardial infarctions yearly, causing 500,000 deaths [1]. The monetary implications of this are staggering, with over 90 billion dollars being spent annually on CAD [1]. As this epidemic has progressed, our understanding of the process of atherosclerosis and CAD has changed and expanded. Paralleling these advances in the pathobiology of atherosclerosis have been data showing that medical treatments effectively diminish the atherosclerotic process. Over the last decade, multiple randomized double blind clinical trials have shown that medical treatment with HMG-CoA reductase inhibitors (statins) significantly lowers LDL-cholesterol and reduces cardiac mortality and morbidity in patients with known CAD and those who are at risk of developing it. The purpose of this article is to review our current understanding of LDL-cholesterol and how it contributes to the development of CAD; how different dyslipidemias affect cardiac risk; and how recently reported clinical trial data suggest that even more aggressive treatment of LDL-cholesterol than recommended by the current National Cholesterol Education Program is indicated for management of patients with CAD and hyperlipidemia. Cholesterol and coronary artery disease: from clogged arteries to an inflammatory disease
Regulation of abscisic acid metabolism in relation to the dormancy and germination of cereal grains

Seed dormancy is of particular importance in the cultivation of cereals, as it directly affects the quality of crop yield. If the dormancy period is too short, this may lead to pre-harvest sprouting, whereas a dormancy period that is too long may cause uneven germination; both of these scenarios are associated with economic losses. Most enzymes engaged in the metabolism of abscisic acid (ABA) have been identified, and significant progress has been made in understanding the role of this phytohormone in the induction and maintenance of dormancy, mainly as a result of research conducted in Arabidopsis . Much less is known about the metabolism and function of ABA in cereal grains, especially in relation to dormancy and germination. This review focuses on the regulation of ABA metabolism in dormant and non-dormant cereal grains, in both the dry state and upon imbibition. Moreover, this review describes the influence of factors such as after-ripening, light, temperature, nitric oxide, and reactive oxygen species (ROS) on the dormancy and germination of cereal grains. These factors, with the exception of ROS, appear to affect the level of dormancy and germination of grains through regulation of ABA metabolism.
Kinetics of the Polyphenolic Content and Radical Scavenging Capacity in Olives through On-Tree Ripening

Olive fruits, as well as their corresponding oil, represent an interesting source of phytochemicals, mainly phenolic compounds, which arise as secondary metabolites, resulting from the plant’s response to biotic and abiotic stresses. Therefore, olive fruits from three distinct cultivars (“Cobrancosa,” “Galega Vulgar,” and “Picual”) grown in Portugal and displaying different degree of resistance to biotic and abiotic stresses have been studied in relation to the concentration of total phenolic compounds, orthodiphenols and flavonoids, besides antioxidant capacity (DPPH, ABTS, FRAP, and ), in three maturation stages and two distinct harvest seasons (2012-2013). Generally, a decrease of all phenolic contents throughout the maturation stages has been observed, while, concerning cultivar, green olives of “Cobrancosa” showed the highest values for all contents assessed, denoting a strong influence of the genetic background. The same trend has not been observed regarding antioxidant activity, since Cobrancosa and Galega Vulgar cultivars presented the highest values only for the DPPH and assays. Moreover, multivariate analyses pointed to the preponderance of the cultivars’ phenolic composition in the semiripe stage for the resistance to biotic stress, with “Galega” the most susceptible cultivar, presenting the lowest contents at this maturation stage, whereas “Picual” displayed the most pronounced phytochemical response.
A Novel Derivative-Based Classification Method for Hyperspectral Data Processing

In hyperspectral classification, a derivative of reflectance spectra is used directly or by fusion with the reflectance spectra. In this way, classification performance is improved. However, on the land cover, especially for plant species, the reflectance spectra may exhibit differences depending on a plant age and maturity level. This situation makes traditional classification methods which are based on time-dependent spectral similarity. In addition, the problem of classification of the species which have similar spectral properties is still valid. As a solution to time dependency and spectral similarity problems, in this study, a new and more generic method based on the spectral derivative is proposed. The method is tested for hyperspectral images which are captured at different time of the year and different places, in the life cycle of species. Test results show that proposed method successfully classifies the land cover time-independent and it is superior to the classical classification methods.
A Few Words about Properties of Inulin Controlling Weight and Health Function

A few words about inulin, natural carbohydrate (Figure 1), present in more than 36000 species of plants including best known like wheat, onion, bananas, garlic, chicory. Inulin in them is used as an energy reserve [4]. One of important properties of inulin is its solubility in water and for this osmotically active. Inulin consists of heterogeneous fructose polymers. Inulin may be polimerizated from 2 to 60. The chainterminating glucosyl moieties and a repetitive fructosyl moiety are linked by β (2,1) bonds not digested by enzymes in human system of food. It has not color and smell so has a little influence on sensory characteristics of food products. Inulin is weakly sweet however high efficiency inulin is not. Inulin is fiber but its solubility is higher than classical fibers, mixed with liquid forms white creamy structure which is similar to fat. Instead of replace fat, inulin may be substitute of sugar and flour.
Intervention of the family health team on treatment adhesion by hypertension patients

Current descriptive study with a quantitative approach comprises an analysis of Family Health Teamsactivities on hypertensive userstreatment adherence, involving 70 professionals from a Family Health Team in Fortaleza CE Brazil. Data were collected through a questionnaire. Educational activities developed for hypertensive userstreatment adherence took the form of individual and group orientations during home visits, clinical visits, lectures, group meetings and conversation groups. The professionalsexperience with regard to hypertensive personsadherence ranged between good, through fair and difficult, and was related to aspects inherent to users, families, professionals and managers. Educative actions and distribution of drugs were important and necessary. Results show that adherence is a big challenge for health professionals, and that the teams intervention should be reconsidered according to the principles of the Brazilian Unified Health System (SUS) and on adherence determining factors.
Characteristics of electron holes generated in the separatrix region during antiparallel magnetic reconnection

In this paper, two‐dimensional particle‐in‐cell simulations are performed to investigate the characteristics of these electron holes generated in the separatrix region of antiparallel magnetic reconnection. The electron holes with bipolar structures of the parallel electric field are formed in the border between the electron inflow channel (where electrons move toward the X line) and outflow channel (where electrons flow away from the X line), where the electrons satisfy the bump‐on‐tail distribution. Quasi‐monochromatic electrostatic waves, which propagate with a speed near the bulk velocity of the fast electron beam, are first excited by the electron bump‐on‐tail instability. These waves then coalesce with each other, and at last electron holes are formed in the separatrix region which then propagate away from the X line along the magnetic field lines.
A crystal-chemical investigation of clinozoisite synthesized along the join Ca2Al3Si3O12(OH)-Ca2Al2CrSi3O12(OH)

Abstract Cr3+-bearing clinozoisite along the join Ca2Al3Si3O12(OH)-Ca2Al2Cr3+Si3O12(OH) was synthesized using cold-seal pressure vessels at PH₂O = 0.35 to 0.40 GPa and T = 500 °C and a piston-cylinder apparatus at PH₂O = 0.8 to 1.5 GPa and T = 500 to 800 °C. Gel-starting materials of Ca2Al3-qCr3+qSi3O12.5 composition with q = 1.00, 0.75, 0.50, and 0.25 were employed to maximize the yields of clinozoisite. Mass fractions of clinozoisite in the experimental products with q = 0.50, 0.75, and 1 were about 70 to 90% along with lesser amounts of eskolaite, garnet, and quartz. Clinozoisite crystallized from the gel with q = 0.25 was associated only with zoisite. The crystal structures of clinozoisite in four runs, containing 0.28, 0.49, 0.50, and 0.62 Cr apfu were refined using X-ray powder diffraction data and the Rietveld method. The amount of Cr3+ at the octahedral M3 and M1 sites ranged from 0.37(1)-0.16(1) to 0.25(1)-0.12(1) apfu, respectively. Corresponding KD = (Cr3+/Al)M1/(Cr3+/Al)M3 values range between 0.57 and 0.73. The M2 site contained only Al. The KD values, and published results for intracrystalline partitioning in epidote and piemontite, show that the preference of Cr3+ for M1 is stronger than that of Fe3+ and Mn3+ in spite of the fact that most Cr3+ is partitioned into M3. Unit-cell parameters of clinozoisite increase with increasing Cr3+. Variations in macroscopic unit-cell parameters can be related to variations in the local M3-Oi and M1-Oi distances.
The rural tourism as development opportunity or farms. the case of direct sales in Sicily.

Tourism has an important role modifying rural communities in their environmental, economic, social and cultural structures, processes and dynamics. In thi s context rural tourism plays a primary role becaus e it is not the rural product that reaches the consumer in the purchase point, but it is the consumer (tourist ) that has to move towards tourist destination to enjoy the pr oduct. So, the aim of this study is to analyse how the opportunities created by the rural tourism can repr esent a vector to promote the growth of farms and territory. Specifically, through a telephone survey conducted among the Sicilian entrepreneurs which j oin to the national network Campagna Amica, it has been analysed how the direct sales in the farm can contrib ute competitiveness to business and therefore to the pe rmanence of man in the territory. The empirical ana lysis has shown that direct sales, associated with the co nventional sales, can represent a growing opportuni ty for farms and whole rural community, leading to an improvement of business economic performances, an increase of investments and a creation of new job o pportunities. This hightligted that agriculture can play a positive role on many components of the territorial system in which it operates.
Technological Capabilities at the National Level: An International Comparison of Manufacturing Export Performance

A large amount of research is showing that technological capabilities (TCs), required to operate a technology efficiently and accomplish any process of technological change, largely explain different productivity levels and industrial performance at the firm-level (Enos, 1991, Lall,1992). In this paper we extend the concept of technological capability to the national level, and analyze its major determinants. The creation of TC depends on a number of factors. They can be grouped in three subsets of factors: incentives, capabilities and institutions. The interaction among them crucially affects the effectiveness of the efforts to create TC. We use this national technological capability (NTC) approach to assess the different manufacturing export performance recorded in a small sample of developing countries (Chile, Colombia, South Korea, Thailand). Different levels of NTC have been detected by looking at how the policies affecting the creation and acquisition of NTC have been carried out in the sample countries over the last two decades. Different incentive systems, investments in capability building, institutional structures and interventions have been observed. These factors remarkably contribute to an explanation of the differential performance in exporting
Surface exposure dating with cosmogenic nuclides

Abstract. In the last decades surface exposure dating using cosmogenic nuclides has emerged as a powerful tool in Quaternary geochronology and landscape evolution studies. Cosmogenic nuclides are produced in rocks and sediment due to reactions induced by cosmic rays. Landforms ranging in age from a few hundred years to tens of millions of years can be dated (depending on rock or landform weathering rates) by measuring nuclide concentrations. In this paper the history and theory of surface exposure dating are reviewed followed by an extensive outline of the fields of application of the method. Sampling strategies as well as information on individual nuclides are discussed in detail. The power of cosmogenic nuclide methods lies in the number of nuclides available (the radionuclides 10Be, 14C, 26Al, and 36Cl and the stable noble gases 3He and 21Ne), which allows almost every mineral and hence almost every lithology to be analyzed. As a result focus can shift to the geomorphic questions. It is important that obtained exposure ages are carefully scrutinized in the framework of detailed field studies, including local terrace or moraine stratigraphy and regional morphostratigraphic relationships; as well as in light of independent age constraints.
Sentiment Analysis of Movie Review using Machine Learning Techniques

Today's online world was fully filled up with blogs, views, comments, posts through various websites and social-surfs. People were habit-uated with posting every incident into blogs, messed with comments like text and emotions, which are a mixed bag of sad, happy, worry, cry etc. Analysing such data was called as Sentimental Analysis. To analysis, these unordered data we use new emerged technology algorithms. Machine learning a transpire technology which is engaged with almost all the fields, where its algorithms are more powerful that give with better faultless results. In this paper, we are analyzing tweets based on movie reviews using the Multinomial Logistic Regression, Naïve Bayes, and SVM algorithms to compare score value to show the best text analysis algorithm.
Two Ext groups and a residue

The present constitutes the key lemma which was hitherto missing in the author's proof of, inter alia, the Green-Griffiths conjecture for surfaces with enough 2-jets, e.g. $13\mathrm{c}_1^2> 9\mathrm{c}_2$. As to why this is so is not the immediate concern of this article since it is a lemma within a whole. By way of what is essentially an appendix to the current paper, a guide to the whole is provided at this http URL
Stent cubierto con pericardio bovino: Evaluación in-vitro, en animales y resultados iniciales en el humano

El stent que se recubre con una membrana (stent-injerto) permite el tratamiento percutaneo de patologia coronaria diversa como aneurismas, ruptura y fistulas (que hasta hace 5 anos solo tenian solucion quirurgica). Ademas, podria reducir las complicaciones embolicas asociadas a la angioplastia de injerto de safena. El objetivo del presente trabajo es evaluar el pericardio bovino como injerto para stents convencionales. In vitro se documento una elasticidad del pericardio bovino de 15% y resistencia a la ruptura de 0.22 kg/mm2, que es mayor a la presion empleada para la liberacion de stents. En 18 cerdos se tuvo exito de implantacion en 29 de 32 stents (90.63%), identificandose los problemas potenciales para su empleo. El estudio histologico de los estudios porcinos agudos documentaron adosamiento correcto del stent a la pared vascular, y los estudios subagudos y cronicos (10 dias y 1 mes) mostraron adecuada endotelizacion y exclusion de proliferacion de la media. Se colocaron 20 stents en 15 pacientes con exito agudo de 100%. Siete pacientes tenian aneurisma coronario y en todos se obtuvo exclusion completa del mismo sin complicaciones. Hubo reestenosis clinica en 2 de 14 pacientes con seguimiento mayor de 6 meses (14.28%); se obtuvo control angiografico en 9 pacientes (incluyendo a los 2 con reestenosis clinica) encontrandose reestenosis en 3 de 14 stents (21.4%), dos de ellos empalmados en la descendente anterior en 1 paciente y uno de 9 implantados en 5 pacientes con lesion en injerto de safena. Se concluye que el pericardio bovino es un material adecuado para su empleo como injerto en stents y se documento su eficacia para el tratamiento de aneurismas coronarios. Estos resultados justifican su evaluacion comparativa en mayor numero de casos para definir mejor su tasa de reestenosis y ubicar su utilidad para el tratamiento de lesiones en injertos de safena
Operational Success of Verbenone Against the Mountain Pine Beetle in a Rural Community

Pouches releasing verbenone, the antiaggregation pheromone of the mountain pine beetle, were stapled to 1191 lodgepole pines throughout 95 residential properties in four subdivisions at Lac le Jeune, British Columbia, in July 2005. Postflight assessment in October in three of the subdivisions, where almost all infested trees had been removed before beetle flight, revealed new mass attacks on 3.6% of 3857 available trees 17.5 cm or greater (7 in) dbh. In a fourth subdivision where no infested trees were removed, 19.6% of 634 available trees were mass-attacked. In contrast, 17.4% of 1145 available trees were mass-attacked within 25 m (27.5 yd) wide, verbenone-treated buffer strips on public forest land adjacent to the residential properties, and 48.3% of 4975 available trees were mass-attacked on untreated control areas beyond the buffer strips. We conclude that treatment with verbenone pouches at roughly 15 m (16.5 yd) centers is a useful tool for protecting trees from attack by the mountain pine beetle provided that verbenone is used as part of a multiyear integrated pest management program that also includes disposal of all infested trees on the area to be protected before beetle flight in midsummer.
IMPROVED METHOD FOR STEREO VISION-BASED HUMAN DETECTION FOR A MOBILE ROBOT FOLLOWING A TARGET PERSON

Interaction between humans and robots is a fundamental need for assistive and service robots. Their ability to detect and track people is a basic requirement for interaction with human beings. This article presents a new approach to human detection and targeted person tracking by a mobile robot. Our work is based on earlier methods that used stereo vision-based tracking linked directly with Hu moment-based detection. The earlier technique was based on the assumption that only one person is present in the environment – the target person – and it was not able to handle more than this one person. In our novel method, we solved this problem by using the Haar-based human detection method, and included a target person selection step before initialising tracking. Furthermore, rather than linking the Kalman filter directly with human detection, we implemented the tracking method before the Kalman filter-based estimation. We used the Pioneer 3AT robot, equipped with stereo camera and sonars, as the test platform.
