Published: April 2020

We study self-gravitating, hydrostatic spheres with a polytropic equation of state P ∝ ρ^γ (where γ is the specific heat ratio of the gas), considering structures with γ ≈ 1 as a model for molecular cloud cores with small departures from isother- mality. We derive the properties (i.e., mass, radius and center to edge density ratio) as a function of γ for the maximal stable sphere through an application of “Bonnor’s stability criterion”. We find that in the γ = 1 → 4/3 range the mass of the maximal sphere (for a given central temperature) is almost constant, and that its radius and center to edge density ratio are growing functions of γ. We therefore have maximal stable, self-gravitating spheres with similar masses, but with increasing center to edge density contrasts for increasing departures from isothermality.
Hα KINEMATICS OF THE ISOLATED INTERACTING GALAXY PAIR KPG 486 (NGC 6090)
Authors: Sardaneta M. M. , Rosado M. , Sánchez-Cruces M.
Published: April 2020

In optical images, the barely studied isolated interacting galaxy pair KPG 486 (NGC 6090) displays similar features to the Antennae (NGC 4038/39) galaxy pair. To compare the distribution of ionized hydrogen gas, morphology and kinematic and dynamic behaviour of both galaxy pairs, we present observations in the Hα emission line of NGC 6090 acquired with the scanning Fabry-Perot interferometer, PUMA. For each galaxy in NGC 6090 we obtained several kinematic parameters, its velocity field and its rotation curve. We also analysed some of the perturbations induced by their encounter. We verified the consistency of our results by comparing them with kinematic results from the literature. The comparison of our results on NGC 6090 with those obtained in a previous similar kinematic analysis of the Antennae highlighted great differences between these galaxy pairs.
SEARCH FOR STABLE ORBITS AROUND THE BINARY ASTEROID SYSTEMS 1999 KW4 AND DIDYMOS
Authors: Oliveira Thais C. , Prado Antonio F. B. A.
Published: April 2020

This work includes analytical and numerical studies of spacecrafts orbiting two binary asteroid systems: 1999 KW4 and Didymos. The binary systems are modeled as full irregular bodies, such that the whole evolution of the results will show the impact of the irregular gravity field in the lifetime and dynamics of the spacecraft’s orbit. The equations of motion of the binary system and the spacecraft are derived from Lagrange Equations. The solar radiation pressure is consired in the dynamics of the spacecraft.Two distinct methods are used to search for stable orbits around the binary systems. One is called the grid search method, which defines the main body as a point mass to estimate the initial state of the spacecraft based on a circular Keplerian orbit. The second method is the search for periodic orbits based on zero-velocity surfaces.
CCD PHOTOMETRY AND EVOLUTIONARY STATUS OF THE PULSATING VARIABLE CSS J051053.0+071722
Authors: Alton K. B.
Published: April 2020

Multi-color (BV I_c ) CCD-derived photometric data were acquired for CSSJ051053.0+071722, a pulsating variable classified as a high amplitude δ Scuti-type system. Analysis of precise time-series lightcurve data was accomplished using discrete Fourier transformation which revealed a mean fundamental mode (f_0 ) of oscillation at 14.5097 ±0.0001 d^−1 along with two other partial harmonics (2f_0 and 4f_0 ). No other statistically significant frequency shared by all bandpasses was resolved following successive pre-whitening of each residual signal. Except for 36 new times-of-maximum light produced from the present study, no other values were found in the literature; therefore, potential secular period changes could not be evaluated. The evolutionary status, age and physical nature of CSS J051053.0+071722 were investigated using the PAdova & TRieste Stellar Evolution Code for generating stellar tracks and isochrones.

Authors: Aso La
Published: April 2020

Abstract
This paper aims at investigating the variations of lexicon having meaning of “produce of sound” in Muna language based on natural semantics metalanguage. The data collecting was done by participant speaking and scrutinize methods through interview and noting techniques. It was analyzed by using natural semantics metalanguage (NSM), an approach to investigate various lexicons with principle “one form for one meaning and one meaning for one form”. Based on the result of this study founded that meaning of “produce of sound” of Muna can be expressed by a number of lexicons and each form has distinctive meaning like in the lexicons of kobheghu, kobhondu, kotighi, kopisi, korasa, korangku, kondii, konduu, kopere, kombote, kopaka, koradha, kobuu, korapa, and kohuhu. All lexicons of Muna language has meaning ‘produce of sound’. The use of each lexicon depends on the sounded object/tool, object/tool that create the sound, and the way of creating the sound.

Homophily and behavior diffusion
Authors: Li Qingjun , Hu Haihua , Yang Wei
Published: April 2020

There is continuing debate over the effect of homophily, which is the tendency for individuals to socialize with similar people, on behavior diffusion. We aimed to clarify this relationship from a social network perspective, using the agent-based modeling approach. The results demonstrate
that homophily promoted the diffusion of behaviors that people had a strong propensity to adopt, but had a prohibitive effect when the adoption propensity was weak. When the adoption propensity was moderate, the effect was promotive at first and then became prohibitive. Moreover, we identified
3 types of homophily—status, value, and mixed (status–value)—and found that mixed homophily was most effective for behavior diffusion, followed by value homophily and then status homophily. These findings highlight the importance of behavior classes and homophily type in
the relationship between homophily and behavior diffusion, and call for a serious consideration of both factors when empirically studying the related issues.
Trust mediates the effect of positive facial expressions on rental intention when using accommodation-sharing platforms
Authors: Wan Xiaoyu , Zhao Han , Wang Tingyi , Zhang Wei
Published: April 2020

Sharing accommodation creates a sense of home between hosts and guests, and fosters interactivity and interpersonal relationships. To clarify how host images influence guests' rental intention, we evaluated the effect of the host's facial expression and analyzed the psychological mechanism
of trust in 3 studies. The conceptual model was verified through data mining in Study 1 and by conducting a simulation in Studies 2 and 3. The results show that a host's positive expression increased guest rental intention and that this effect was mediated by trust. Practical and theoretical
implications of the results are discussed.
Effects of social exclusion and implicit theories of personality on nostalgic consumption
Authors: Xu Wei , Jin Xiao-Tong
Published: April 2020

We conducted 2 studies to examine how social exclusion and implicit theories of personality interact to influence preferences for products that evoke nostalgia. In Study 1 we tested how individuals' implicit personality (entity vs. incremental theorist type) moderate the effects of
social exclusion on nostalgic consumption. Results showed that socially excluded (vs. socially included) consumers were more likely to consume nostalgic products when the consumers were entity (vs. incremental) theorists. In Study 2 we conducted a different manipulation of social exclusion
and individuals' implicit personality, and also examined the mediating role of self-continuity. Results showed that self-continuity mediated the interaction effect of social exclusion and implicit personality on preferences for nostalgic products. The results were robust whether the manipulation
of social exclusion was in an online dating or fitness club application context, and for different nostalgic product choices, comprising chips and cookies.
Analysis of energy and major components in chromatographic signals for the diagnosis of prostate cancer
Authors: Soto Vergel Ángelo Joseph , Mendoza Luis Enrique , Medina Delgado Byron
Published: April 2020

The prostate exam is an early detection tool to prevent prostate cancer and the main diagnostic tools for obtaining signs are generally invasive. This article tries chromatographic signals from the urine of prostate cancer patients and control patients as a non-invasive examination proposal. For this purpose, methodologically, urine samples are taken, digitized in chromatograms, treated with mathematical techniques and classified. The mathematical techniques are time normalization, dead time elimination, baseline correction, noise elimination, and peak alignment. Classification techniques analyze energy, in the domain of time and frequency, and the main components in sedimentation graphs and scores. As a result, the chromatographic signal is characterized and identifies the characteristic curve that represents the signal of prostate cancer patients and control patients. The data structure shows a cluster distribution of 88.88% of the vectors for the control patients. In the case of prostate cancer patients, the distribution of data is in clusters around the area defined by control patients. This characterization demarcates signal classification regions to diagnose possible prostate cancer patients, validating the relationship between the chromatographic signal and cancer.

Published: April 2020

The shelf-life of a pasteurized blackberry juice with added calcium and vitamin C was evaluated in the present work. The product underwent physicochemical, microbiological, and sensory characterization at 25, 35, and 45 °C for 30 days at 80% relative humidity. An analysis of variance was performed to determine the variable most affected during storage. The results showed that mesophilic microorganisms were detected on day 21 of storage at 15 °C, at day 18 at 25 °C, and at day 11 at 35 °C. Integrated kinetic and Arrhenius mathematical models were obtained for the physicochemical variables L *, a *, b *, brix, pH, and viscosity. The kinetic models of the sensory behavior of the blackberry pulp stored at 25 °C were obtained. It was possible to sensorily determine that the product was rejected on average for all descriptors at 12 days.

Authors: Velasco Arango Viviana Andrea , Sotelo Barbosa John Edwin , Ordoñez Santos Luis Eduardo , Hleap Zapata José Igor
Published: April 2020

Papaya (Carica papaya L) is some fruit rich in antioxidants and an important source for obtaining bioactive compounds. Its production, worldwide for the year 2017, was 13.3 million tons. In its industrial processing is obtained approximately between 15 and 20%, in relation to the weight of the fruit, of husks or epicarp, which are likely to be used in order to obtain organic compounds such as carotenoids and polyphenols, among others, contributing, in addition, to mitigate the effects on the environment, since generally, these shells are thrown into landfills of solid waste, generating serious problems of environmental pollution. The objective of this research was to characterize physicochemically the carotenoid pigments obtained from the papaya epicarp. A papaya epicarp flour was processed and it was determined, both in it and in the fresh epicarp, pH, titratable acidity, moisture content and dry matter. Likewise, the carotenoid content, the antioxidant activity and the content of phenolic compounds were determined. The results showed high values for physicochemical parameters. The content of carotenoid compounds for the fractions of β-carotene, α-carotene, β-cryptoxanthin, Zeaxanthin and lycopene ranged between 8,587 and 4,070 mg/100g of epicarp, with the highest value corresponding to β-cryptoxanthin and the lowest value the lycopene fraction. The antioxidant activity, expressed as inhibition of the DPPH radical, gave a value of 58.77 ± 3.038 IC50 mg/ml. The content of phenolic compounds measured in mg of gallic acid equivalents/g gave a result of 24.948 ± 0.728. The data obtained allow us to conclude that said flour can be used as a source of bioactive compounds and natural pigments both in the food industry and in the technical and pharmaceutical industries.
Environmental services of water resources, as part of the Ocaña region city proposal
Authors: Alba Maldonado José Manuel , Valdes Solano Diana Milena , Durán Durán Sandra
Published: April 2020

The article establishes a conceptual framework of the Ocaña region city, taking as axis the environmental services of the water resource; in this sense, a reflection is made around the city region and environmental services, and subsequently a cartographic delimitation is made of what could be a proposal of the Ocaña Region city based on water resources through the basins where it is supplied. As a main result, a delimitation was designed on how Ocaña should be understood from the water supply and responsibilities regarding its use with the other municipalities, due to this, the Algodonal River is taken as the main water source of the city and as references, the municipalities with which the city is related, with a view to contributing to a proposal of the Ocaña region city. It was possible to identify the relations of the city of Ocaña with the water environmental services of the region, highlighting on the one hand its relationship with other municipalities, strategic ecosystems and water basins. Cartographically delimited a proposal of city region starting from the ordering of the basin of the cotton river, dividing it into high, medium and low basin. It is concluded that the city of Ocaña has been built from its environmental relations with the region and that this leads to the need to plan a new city model, based on the recognition and responsibility of this within a proposal of the city region.

Published: April 2020

In this research the effect of edible coatings based on aloe vera and cassava starch on the physicochemical properties and the kinetic parameters of degradation of ascorbic acid (AA) in pineapple minimally processed during 16 days of storage at 4 ° C was evaluated. Five treatments (T1, T2, T3, T4 and T5) were tested, pineapple “honey gold” with coating solutions of different aloe vera / starch concentrations (100/0, 75/25, 50/50, 25/75 and 0/100 respectively), and a control treatment (T6 ) that corresponds to fruit without coating. The coatings were carried out by immersing the fruit previously processed for 1 minute. The results show that the treatment with the best pH values, titratable acidity (AT) and maturity index (IM) was T3 (pH: 3.61, AT: 0.0480, IM: 2.915), in terms of moisture and soluble solids (SS) the T1 treatment (% Moisture: 81.725) and T4 (SS: 11.19) showed the most optimal values. The model that best described the degradative behavior of AA is zero order, being the T4 treatment the most adequate to preserve vitamin C with a value (k: 0.781), a half-life (t ½: 28 days) and a decimal reduction time (D: 93 days).
Design and implementation of a preliminar dendromorphical or arborescent key for the identification of the botanical families of the arboreal species of San José de Cúcuta
Authors: Carvajal Valderrama Evaristo
Published: April 2020

The knowledge in biodiversity and the use of botanical terminology is fundamental for ordering and landscape conservation of a city. In San José de Cúcuta, there is no knowledge of tree arboreal species, leading to an inadequate use of trees, triggering inconveniences in electrical networks, aqueducts and sewage systems. The objective of the study was to design and implement an arborescent (or dendromorphic) key as a methodological tool for the identification of native (or naturalised) tree families located in the urban and peri-urban areas of the city of San José Cúcuta. It was considered preferentially the vegetative characteristics and those peculiarities of the plants that are readily observable such as phyllotaxy, the composition and edges of the leaves, the exudate, the presence of spines or aculeos, the presence or absence of glands, pulvinids or stipes, dead bark and live, smells, colors and scores on the sheets, etc. Once the families were identified through the key, a manual was elaborated describing the essential characteristics for their recognition, which includes detailed and panoramic images, as well as excellent morphological descriptions in order to make a comparison to verify if the identifier corresponds to the family found by implementing the use of the arborescent key. By the identification and management of trees, a diversification and appropriate selection of tree species can be established that can make a useful contribution to the physiological, sociological and economic well-being of urban society, contributing to the region's environmental sustainability strategy. The knowledge of tree species is a foundation to guide and define policies towards the landscape planning of the city, aimed at its protection and conservation, as well as the enjoyment of the benefits and ecosystem services provided by the urban vegetation of the city of San José of Cúcuta, recognized nationally as the "Green City of Colombia".

The Value of Implicit Political Connections
Authors: Broadstock David , Chen Xiaoqi , Cheng C. S. Agnes , Huang Wenli
Published: April 2020

We investigate whether the aggregated political relations of a firm's top management team (TMT) add value to the firm's performance. We distinguish between the political relations that arise from TMT's own work experience, which are termed direct political connections (DPC), and the relations that TMT develops from working for the same institution with the government officials, which are termed implicit political connections (IPC). We find that IPC are positively associated with firm performance and that they often have a stronger effect than DPC do. We also find that the effect of IPC on firm value is stronger in SOEs and in firms located in under-developed provinces. Moreover, we find that after the anti-corruption campaign, the effect of DPC decreases but the effect of IPC does not significantly change. Overall, our results suggest the importance of investigating a firm's aggregated political connections, especially its IPC.

T
cells isolated from the pancreatic infiltrates of non-obese diabetic mice have
been shown to recognize epitopes formed by the covalent cross-linking of
proinsulin and secretory granule peptides.
Formation of such hybrid insulin peptides (HIPs) was confirmed through
mass spectrometry and responses to HIPs were observed among the islet-infiltrating
T cells of pancreatic organ donors and in the peripheral blood of individuals
with type 1 diabetes (T1D). However, questions
remain about the prevalence of HIP-specific T cells in humans, the sequences
they recognize, and their role in disease.
We identified six novel HIPs that are recognized in the context of
DRB1*04:01, discovered by utilizing a library of theoretical HIP sequences
derived from insulin fragments covalently linked to one another or to fragments
of secretory granule proteins or other islet-derived proteins. We demonstrate that T cells that recognize
these HIPs are detectable in the peripheral blood of subjects with T1D and
exhibit an effector memory phenotype. HIP-reactive
T cell clones produced Th1-associated cytokines and proliferated in response to
human islet preparations. These results
support the relevance of HIPs in human disease, further establishing a novel
post-translational modification that may contribute to the loss of peripheral
tolerance in T1D.
The Socio cultural Impacts of Tourism
Authors: Mason Peter
Published: April 2020

When discussing the socio-cultural impacts of tourism there is a need to first understand the terms society and culture. The concept of society is studied, in particular, within the subject of sociology. Sociology is largely concerned with the study of society and focuses on people in groups and the interaction of those in groups, their attitudes and their behaviour. Culture is a similar concept to society and is about how people interact as observed through social interaction, social relations and material artefacts. According to Burns and Holden (1995), when discussing culture within the context of tourism, they indicate that it consists of behavioural patterns, knowledge and values which have been acquired and transmitted through generations. Burns and Holden (1995:113) provide more detail when they indicate that “culture .... includes knowledge, belief, art, moral law, custom and any other capabilities and habits of people as members of society’”
Weather and Climate
Authors: Mason Peter
Published: April 2020

Weather can be regarded as a vital resource for tourism, and Robinson (1976) suggested weather was a major element which contributes to tourism development. Although it is seen as less important in Peters’ (1969) grouping (see Chapter 3), Boniface and Cooper (2001) devote a separate chapter to climate, suggesting its importance for tourism, and this book follows suit with an entire chapter containing a discussion of weather and climate. However, it is climate (‘average weather conditions over a period of time’) that is particularly significant and Holden (2016) considers it to be the most important factor affecting tourism. This chapter discusses weather as a resource for tourism, and stresses that weather (and the related concept of climate) provides a very significant context for many tourism activities. The discussion below indicates that variations in climate occur in regular annual cycles and we refer to these as seasonal changes. The seasons, the cause of which is explained below, are a very significant aspect of tourism and the seasonality of tourism is largely the result of climate.
The Economic Impacts of Tourism
Authors: Mason Peter
Published: April 2020

For approximately 40 years from the early 1960s, the ‘impacts of tourism’ was the most researched topic in tourism, and economic impacts were more researched than any other type in this period. When, in the late 1980s, Pearce discussed research on tourism impacts, he stated that the geographical focus of this research, was the tourism destination. As Pearce (1989:2) indicated: Studies of the impact of tourist development on a destination or destinations have been the largest single element of tourism research ... and has concentrated on the effects of income and employment. Despite this quotation coming from nearly 30 years ago, and taking into account the development of many different research areas in tourism since then, it is still the case that economic impact studies are a key focus in tourism research. Although, as has been stated in Chapter 6, economic impacts of tourism are linked to, and cannot easily be separated from, other types of impact, largely in an attempt to assist with understanding, economic impacts are discussed in this chapter separately from other tourism impacts.
Climate Change
Authors: Mason Peter
Published: April 2020

Climate change poses a major threat to almost all forms of human activity on earth, including tourism. As Holden (2016: 227) argues: Of all the challenges facing tourism’s relationship with nature, it is not an exaggeration to state that climate change represents the greatest. Holden gives as his rationale for this statement that it is the stability and predictability of climate that is vital for the environments and ecosystems that are required for the continuation of current types of tourism, whether these are the traditional form of mass tourism, in terms of ‘sun, sea and sand’ holidays, or a niche activity which involves visiting a tropical rain forest with rare flora and fauna as the main attraction. Climate change also presents opportunities for tourism. If areas currently experiencing cool winters and mild summers get warmer, then new types of tourism may be possible including beach-based holidays where at present these are of little importance. Climate change is likely to lead to modifications in the weather at different times of the year so ‘seasonality’ which is currently a very important dimension to many forms of tourism will be affected, probably to the extent that seasons when there is high tourism activity will get longer in some parts of the world. Although tourism is likely to be significantly affected by climate change, it has also contributed to climate change through for example the burning of fossil fuels in transport for tourism as well through the use of power in hotel accommodation.
The Future of Tourism
Authors: Mason Peter
Published: April 2020

For the past 50 years or so, tourism as a socio-economic phenomenon has been steadily growing, despite what can be seen today as temporary blips in which growth has slowed or numbers have actually fallen for a short period. Some of these factors leading to a decline or a slowing in growth have been as a result of natural causes and others have occurred following human induced changes. Looking to the future, there are a number of factors that can assist in the further growth and development of tourism and yet other factors that can restrict development and even turn growth into decline. This chapter considers future developments in tourism.
Protected Areas
Authors: Mason Peter
Published: April 2020

There are a significant number of protected areas in the world today, but their creation has occurred only relatively recently. The designation of protected areas can be linked back to the Romantic Movement in England and continental Europe (Mason, 2016). A related movement in the USA also contributed significantly to the establishment of pro- tected areas there. As indicated in Chapter 3, until the latter part of the 18th century, large areas of the natural landscape were not looked upon as having much potential for human use. So mountain regions, such as the Alps, were viewed as a barrier to communication and transport, and similarly uplands and mountain areas in the UK were viewed as offering little scope for economic use, except possibly sheep farming. This chapter indicates that the first protected areas were established in the USA, provides a case study of the very first national park, Yellowstone Park, and discusses the issues that can arise when the designation as a park acts as form of marketing and leads to increasing numbers of visitors with the related impacts. The chapter also discusses changing concepts of the term ‘wilderness’, the implications of this and provides a case study of the largest and most remote wilderness on earth, Antarctica.
An Introduction to Tourism Impacts
Authors: Mason Peter
Published: April 2020

Tourism, as a significant form of human activity, can have major effects on people and places, and these effects are commonly referred to as tourism impacts. Tourism always takes place in a context, which we usually refer to, in a broad sense, as the environment. This environmental context is made up of both human and natural features. The human environment comprises economic, social and cultural factors and processes. The natural environment is a combination of inorganic components such as rocks and water, and inorganic processes such as the erosion of rocks, and with organic elements, which comprise plants and animals and organic processes such as those within an ecosystem.

Либерализация системы ЖКХ создала вакуум социальной ответственности: власти сложили ее с себя на граждан, а те, в свою очередь, ответственность за общее имущество не приняли. В результате у новых собственников многоквартирных домов возникли существенные искажения в экономических отношениях с поставщиками услуг и ресурсов для нужд проживания в доме. В связи с этим существует необходимость в новых подходах в организации местного самоуправления.

The liberalization of the housing and utilities systems created vacuum of social responsibility: the authorities laid it on the citizens, and they, in turn, did not accept responsibility for the common property. As a result, new owners of apartment buildings have experienced significant distortions in their economic relations with providers of services and resources for the needs of living in the house. In this regard, there is a need for new approaches in the organization of local self-government.
