Industry 4.0 will fundamentally change the way of life, work and attitude towards each other; the role of public administration is increasing many times. The government should develop measures for implementation in enterprises as the well-being of the nation as a whole depends on the success of business structures. The activity of an enterprise in a market economy is characterized by a system of risks and uncertainties that arise due to the inability to evaluate the prospects of a market situation through functional dependence. The solution of this problem is based on statistical, mathematical methods of analysis, the use of which is simplified with the widespread use of computer technology ARM systems, etc. Authors in the article describe Top 5 global risks in 2019, according to the World Economic Forum, consider the investment risks and propose to calculate the effectiveness of financial investments using Fisher's criterion.

in the cloud store the data and use it from anywhere in the world but the users are worried of the data stored on the cloud in aspect of data integrity and validation of data. Therefore we are using Third Party Auditor (TPA) to ensure data integrity for ensuring data correctness on cloud. There are many auditing schemes existing but they have limitation so that we come up with a new approach of auditing. In this paper we have implemented a new scheme which efficient in performance over the cloud. It consists with two key one with users private and other with user’s public key. The user key has created a hash value from all the data with encoding framework. TPA performs the validation of data throughout any user’s action over the cloud. TPA generate the own signature and validate with users signature and keep the log of data all the time. It matches the both signature for data correctness .Validation of data shows the movements on users demand. The server keeps the all data watch over the performing action by users and TPA. The main objective is to show the correctness of data on cloud, maintain the integrity of data and provide a secure channel for privacy over the cloud usage. We have frame architecture to minimize the cost of cloud with TPA where minimum use of data on the TPA side. The system supports to batch auditing process and dynamic updating in usage

The world is in need of food, water, Shelter and without any of these there is no possibility to live. Agriculture is backbone of our nation which indeed supplies food for the entire people but the producers of food are facing many problems like moisture content, fertility of soil which affects the farming. Because of this reason cultivation and production of food grains are decreased. Current scenario is that the farmers need to go research center to test the fertility content of soil and to predict kind of plants can be cultivable in that land. In this paper perfect cultivable plants can be detected properly without approaching soil research centers which consumes more money as well time. By the application of pH sensors the fertility of soil can be measured. By measuring the pH soil nutrient content can be measured and so the suitable cultivable crop for different soil varieties can be predicted. In this view to give a healthful support to farmers, soil nutrients are analyzed and report the requirement using advanced sensors.

Impedance Cardiography (ICG) evaluation facilitates the volume of heart stroke in the sudden cardiac arrest. It is a noninvasive method for measurement of stroke volume, cardiac output monitoring and observing the hemodynamic parameters by changes in the body blood volume. Bloodvolume changes caused due to various physiological processes is extracted in the form of the variations in the impedance of the body segment. In the real time clinical environment during the extraction the ICG signals are influenced with several artifacts.As these artifacts are not stationary in nature, we can’t predict their characteristics. Hence,we developed several hybrid adaptive filtering mechanisms to improve the ICG signals resolution. Least mean square (LMS) algorithm is the basic enhancement technique in the adaptive filtering. However, in the non-stationery situation the LMS algorithm suffers with low rate of convergence and weight drift problems. In this paper we developed some hybrid variantsof LMS algorithm those are Leaky LMS (LLMS) for ICG signal enhancement. More over to progress the convergence rate, filtering capability and to reduce the computational complexity we also developed various sign versions of LLMS algorithms. The sign variants of LLMS algorithms are sign regressor LLMS (SRLLMS), Sign LLMS (SLLMS), and Sign Sign LLMS (SSLLMS). Severaladaptive signal enhancement units (ASEUs) are developed based on adaptive algorithms and performance is evaluated on the real ICG signal taken from MIT-BIT database. To ensure the efficiency of these algorithms, four experiments were performed to eliminate the various artifacts such as sinusoidal artifacts (SA), respiration artifacts (RA), muscle artifacts (MA) and electrode artifacts (EA). Among these techniques, the ASEU associated with SRLLMS performs better in the artifacts filtering process. The signal to noise ratio improvement (SNRI) for this algorithm is calculated as 9.3388 dBs, 5.7514 dBs, 8.4449 dBs and 8.7358 dBs respectively for SA, RA, MA and EA. Hence, the SRLLMS based ASEUs are more suitable in ICG signal filtering in real time health care sensing systems.

Agricultural productivity along with good nutrition plays a major role in addressing human health. The major source of nutrients for the growth of plants is soil.. The three main nutrients needed by plants are Phosphorus (P),Nitrogen (N) and silver-white element (K) square which are combined and made them into a single name thetrio(NPK). Other important nutrients are calcium, magnesium, and sulphur. Smart Agriculture helps in identifying the nutrient contents present in the soil and also thereby increase the crop yield. The proposed work helps farmers to identify the nutrient contents present in the soil and also helps farmers to identify the type of crops that can be grown on the soil. An automated system can be developed for detecting moisture level, temperature, humidity, pH level in the soil. It also notifies the farmer with an alert message in case of fire. These values are obtained from individual sensors and they are sent to the cloud using Wi-Fi module. Using the API (Application Programming Interface) keys those values are transferred to the mobile application, through which the farmers can monitor their crops remotely. This mobile application also helps the farmers by suggesting a different type of crops that can be grown based on the pH level of the soil. It also suggests the farmers with the amount of limestone and sulphur to be added in the soil in order to raise or lower the pH value by 2.

Modular construction is a construction method where pre-designed building units are constructed off-site, conveyed to site as components and assembled to form a building or structure. The construction method is adjudged to significantly reduce building time and offers good economic value which are some of its key benefits over traditional construction methods. This study evaluated architects’ awareness level and adoption of modular construction method in Nigeria, in order to ascertain its application level towards providing prompt affordable housing projects delivery in the country. The study is a survey research that engaged a pragmatic research approach. Both qualitative and quantitative inquiry methods were employed to carry out the research. Qualitative inquiry method was employed to gather relevant data used to develop a structured questionnaire that was used to collect quantitative data. The questionnaire was distributed to a hundred architects who were randomly selected from a hundred architectural firms registered to practice in Lagos State, the most populous state in Nigeria. A total of seventy-one participants provided data for the study. The data were analysed with statistical package for social sciences (SPSS) software, version 21. The result depicts that majority (87%) of the respondents are aware of modular construction as an approach used in building construction, but just few (32%) of the respondents have adopted modular construction in the delivery of affordable housing scheme in the study area. In addition, it was found that modular construction for affordable housing projects is mostly adopted for its waste reduction, construction time reduction and cost saving benefits. The study concludes that though architects’ awareness level of modular construction method and its benefits is high in Nigeria, its adoption by the architects for prompt delivery of affordable housing projects in the study area is low. Hence, appropriate measures were recommended to enhance the adoption of modular construction method by architects to combat housing challenges experienced in Nigeria.

Abstract

 

The clove flower essential oil (Syzygium aromaticum) with the active compound eugenol has been widely investigated and is known to be efficacious as an anti-inflammatory agent, and further research on its formulation continues. The formula developed in this study was a topical ointment dosage form using a water soluble base (oleic acid enhancer and propylene glycol). This study aims to determine the physical and irritant properties of the clove flower essential oil ointment (MABC) if a hydrocarbon base is used. The ointment is made by the smelting method with a concentration of 5% (F1), 10% (FII) and 15% (FIII). The ointments of the three formulas were then evaluated for their physical properties, including dispersion, adhesion and pH. The results of statistical tests with the LSD test showed that there were significant differences between formulas. The higher the concentration of MABC, the greater the spread (p0.05). The results of the Simplex Lattice Design irritation test also show that water-soluble base ointment with a concentration of 5%, 10% and 15% MABC does not cause an irritating effect.

Using Ranking Data to Understand International Surfers' Travel Motivations
Authors: Porter Brooke A. , Usher Lindsay E.
Published: October 2019

Some emerging destinations are looking to surf tourism as a development strategy. Surf tourism stakeholders can better govern surf tourism development if they know more about the surf travelers themselves. To better understand the behavior of surf tourists, this research uses ranked
data to explore items in three major categories: 1) surf-related travel attributes; 2) destination attributes; and 3) general experience attributes. Findings suggested that swell consistency and wave size, accommodation, and escapism were among the most popular items, while aspects such as
surf photography, nightlife, and access to competitions were among the least popular. These preliminary findings may assist emerging destinations in their surf tourism development plans as well as identify important areas for future research.
Passenger Safety on Whale-Watching Vessels in Australia
Authors: Wilks Jeff , Lück Michael , Orams Mark
Published: October 2019

To date, the focus of research into risks and safety in whale watching has tended to be on the safety of the whales (or dolphins/porpoises). This article explores the issue from the human side of the interaction and considers boat-based whale-watching passenger safety by reviewing evidence
from available legal case records and legislation in Australia to better understand the risks and injuries that can occur to people in these marine wildlife tourism scenarios. A review of two legal cases and observations from media reports of whale-watching incidents in other jurisdictions
revealed that waves and associated violent vessel movement are responsible for serious injuries to passengers. Where there was a failure to keep a proper lookout for waves and safely adapt to changing sea conditions operators have been found negligent. Legal challenges have also been successful
in cases involving inaccurate and misleading promotion and communication about the nature of the tour and associated risks, and where passengers had not received adequate safety briefings. Furthermore, signed waivers that sought to protect the tour operator from responsibilities for injuries
sustained aboard were not sufficient to absolve operators from liability. Given the different cultures, languages, and physical capabilities of a diverse range of international tourists interested in whale watching it is recommended that promotional materials, safety briefings, and safety
communications (such as warning signs) be communicated by widely used and understood symbols and in multiple languages. In addition, some screening of passengers to ascertain preexisting medical conditions and to assess their ability to participate in the voyage safely, and with understanding
of safety instructions, should be undertaken prior to a vessel leaving the dock. Templates to assist operators with their responsibilities are now available from the Australian Maritime Safety Authority.
Constraining Mass-transfer Histories of Blue Straggler Stars with COS Spectroscopy of White Dwarf Companions

Published: October 2019

Recent studies show that the majority of blue straggler stars (BSSs) in old open clusters are formed through mass transfer from an evolved star onto a main-sequence companion, resulting in a BSS and white dwarf (WD) in a binary system. We present constraints on the mass transfer histories of two BSS–WD binaries in the open cluster NGC 188, using WD temperatures and surface gravities measured with Hubble Space Telescope COS far-ultraviolet spectroscopy. Adopting a Gaia-based cluster distance of 1847 ± 107 pc, we determine that one system, WOCS 4540, formed through Case C mass transfer resulting in a CO-core WD with T
eff =

K and a log g =

, corresponding to a mass of

M
⊙ and a cooling age of

Myr. The other system, WOCS 5379, formed through Case B mass transfer resulting in a He-core WD with T
eff =

K and a log g =

, corresponding to a mass of

M
⊙ and an age of

Myr. The WD parameters are consistent across four different cluster distance assumptions. We determine possible progenitor binary systems with a grid of accretion models using MESA, and investigate whether these systems would lead to stable or unstable mass transfer. WOCS 4540 likely resulted from stable mass transfer during periastron passage in an eccentric binary system, while WOCS 5379 challenges our current understanding of the expected outcomes for mass transfer from red giant branch stars. Both systems are examples of the value in using detailed analyses to fine-tune our physical understanding of binary evolutionary processes.

We analyze extensive spectroscopic and photometric data of the hypervariable quasar SDSS J141324+530527 (RMID 017) at z = 0.456, an optical “changing-look” quasar from the Sloan Digital Sky Survey Reverberation Mapping project that increased in optical luminosity by a factor ≃10 between 2014 and 2017. The observed broad emission lines all respond in luminosity and width to the changing optical continuum, as expected for photoionization in a stratified, virialized broad emission line region. The luminosity changes therefore result from intrinsic changes in accretion power rather than variable obscuration. The variability is continuous and apparently stochastic, disfavoring an origin as a discrete event such as a tidal disruption flare or microlensing event. It is coordinated on day timescales with blue leading red, consistent with reprocessing powering the entire optical spectral energy distribution. We show that this process cannot work in a standard thin disk geometry on energetic grounds, and would instead require a large covering factor reprocessor. Disk instability models could potentially also explain the data, provided that the instability sets in near the inner radius of a geometrically thick accretion disk.
Understanding Lyα Nebulae at Low Redshift. I. The Sizes, Powering, and Kinematics of “Green Bean” Galaxies
Authors: Prescott Moire K. M. , Sanderson Kelly N.
Published: October 2019

A new but rare sample of spatially extended emission line nebulae, nicknamed “Green Beans,” was discovered at z ≈ 0.3 thanks to strong [O iii] emission, and subsequently shown to be local cousins of the Lyα nebulae found at high redshift. Here we use follow-up APO/DIS spectroscopy to better understand how these low-redshift Lyα nebulae compare to other populations of strong emission line sources. Our spectroscopic data show that low-z Lyα nebulae have active galactic nucleus (AGN)-like emission line ratios, relatively narrow line widths (FWHM ≲ 1000 km s−1), and emission line kinematics resembling those of Type 2 AGN at the same redshift, confirming that they are powered by Type 2 AGN with typical ionizing continua. While low-z Lyα nebulae are larger and less concentrated than compact, star-forming Green Pea galaxies, we find that they resemble typical Type 2 AGN in terms of r-band concentration and size. Based on this pilot study, low-z Lyα nebulae appear to be a subset of Type 2 AGN with bluer optical continua and high [O iii] equivalent widths but with comparable sizes and similar [O iii] kinematics. These characteristics may simply reflect the fact that low-z Lyα nebulae are drawn from the high-luminosity end of the Type 2 AGN distribution, with higher nuclear activity driving higher [O iii] equivalent widths and more central star formation leading to bluer optical continua. Deeper spectroscopic follow-up of the full sample will shed further light on these issues and on the relationship between these low-z Lyα nebulae and the Lyα nebula population at high redshift.

The origin of the extended soft X-ray emission around nearby highly inclined disk galaxies (often called the X-ray corona) remains uncertain. The emission could arise from volume-filling hot gas and/or its interaction with cool gas. Morphological properties of the X-ray emission can provide additional information to distinguish these different origins. We define model-independent parameters H
50, H
75, and H
95—vertical scales that enclose 50%, 75%, and 95% of the total flux of the emission, respectively. We study the correlation of these parameters with galaxy properties inferred from infrared observations of a sample of nearby highly inclined disk galaxies with high-quality Chandra data. We find weak negative correlations between H
50 or H
75 and the surface star formation rate (I
SFR), and no correlation for H
95. However, we detect strong negative correlations of the vertical concentration of the emission, defined as H
50/H
95 or H
75/H
95, with I
SFR. Our findings suggest that the X-ray emission around disk galaxies is likely comprised of two components: the extended, weak emission, characterized by H
95, is influenced by the outflowing hot gas entrained in star formation driven winds, whereas the strong emission close to the disk, which is often rich in cool gas characterized by H
50 or H
75, is largely impacted by cool–hot gas interaction.
Pulsar Glitch Activity as a State-dependent Poisson Process: Parameter Estimation and Epoch Prediction
Authors: Melatos A. , Drummond L. V.
Published: October 2019

Rotational glitches in some rotation-powered pulsars display power-law size and exponential waiting-time distributions. These statistics are consistent with a state-dependent Poisson process, where the glitch rate is an increasing function of a global stress variable (e.g., crust-superfluid angular velocity lag), diverges at a threshold stress, increases smoothly while the star spins down, and decreases step-wise at each glitch. A minimal, seven-parameter, maximum likelihood model is calculated for PSR J1740−3015, PSR J0534+2200, and PSR J0631+1036, the three objects with the largest samples whose glitch activity is Poisson-like. The estimated parameters have theoretically reasonable values and contain useful information about the glitch microphysics. It is shown that the maximum likelihood, state-dependent Poisson model is a marginally (23%–27%) better post factum “predictor” of historical glitch epochs than a homogeneous Poisson process for PSR J1740−3015 and PSR J0631+1036 and a comparable predictor for PSR J0534+2200. Monte Carlo simulations imply that ≳50 glitches are needed to test reliably whether one model outperforms the other. It is predicted that the next glitch will occur at Modified Julian Date (MJD) 57,784 ± 256.8, 60,713 ± 1935, and 57,406 ± 1444 for the above three objects, respectively. The analysis does not apply to quasiperiodic glitchers like PSR J0537−6910 and PSR J0835−4510, which are not described accurately by the state-dependent Poisson model in its original form.

Exoplanets orbiting pre-main-sequence stars are laboratories for studying planet evolution processes, including atmospheric loss, orbital migration, and radiative cooling. V1298 Tau, a young solar analog with an age of 23 ± 4 Myr, is one such laboratory. The star is already known to host a Jupiter-sized planet on a 24 day orbit. Here, we report the discovery of three additional planets—all between the sizes of Neptune and Saturn—based on our analysis of K2 Campaign 4 photometry. Planets c and d have sizes of 5.6 and 6.4

, respectively, and with orbital periods of 8.25 and 12.40 days reside 0.25% outside of the nominal 3:2 mean-motion resonance. Planet e is 8.7

in size but only transited once in the K2 time series and thus has a period longer than 36 days, but likely shorter than 223 days. The V1298 Tau system may be a precursor to the compact multiplanet systems found to be common by the Kepler mission. However, the large planet sizes stand in sharp contrast to the vast majority of Kepler multiplanet systems, which have planets smaller than 3

. Simple dynamical arguments suggest total masses of <28

and <120

for the c–d and d–b planet pairs, respectively. The implied low masses suggest that the planets may still be radiatively cooling and contracting, and perhaps losing atmosphere. The V1298 Tau system offers rich prospects for further follow-up including atmospheric characterization by transmission or eclipse spectroscopy, dynamical characterization through transit-timing variations, and measurements of planet masses and obliquities by radial velocities.

Published: October 2019

Esta pesquisa tem por objetivo investigar e analisar, sob a ótica do produtor rural, o volume e os fatores que afetam as perdas na colheita de grãos de soja na região Oeste do Paraná. Para a obtenção dos resultados foram coletados dados primários por meio de entrevistas com 243 produtores rurais em 8 municípios da região. Os resultados apontaram que, apesar do desenvolvimento e modernização do setor, ainda existem perdas passíveis de controle, isso se deve, sobretudo, a fatores como o grau de especialização dos operadores de maquinário e imprevisibilidade do clima. Ademais, pode-se verificar que as perdas relativas ao relevo e topografia da área estão intimamente relacionadas à modernização e idade do maquinário utilizado. Constata-se que, para a melhora desse quadro, faz-se necessário fomentar especialmente a especialização dos produtores a fim de que utilize todo o potencial da tecnologia e instrumental disponível para o setor agrícola.

Ecotone has been defined as “a multi-dimensional environmentally stochastic interaction zone between ecological systems with characteristics defined in space and time, and by the strength of the interaction” (Hufkens et al. 2009). This is a known concept to define transitional zones between two or more ecological communities, ecosystems or biotic regions. Ecotone forests, dispersed in northern Brazilian Amazonia, are natural formations which have been largely affected by anthropogenic impacts, such as deforestation and fire. Maracá Ecological Station, State of Roraima, Brazil, is a protected area with extensive representations of ecotone forests in this region of the Amazonia. Forest inventories and floristic surveys are important as they extend our knowledge (1) of forest structure and tree species composition and (2) of tree and palm species ecology in this region of the Amazonia. Both improve our ability to predict changes in plant diversity, considering the future scenarios of climate change in comparison with previous surveys performed in Maracá.

We present a forest inventory carried out in 129 plots (10 m x 50 m; 6.45 ha in total) dispersed in a grid (5 km x 5 km) located in a forest zone ecotone in the eastern part of Maracá Ecological Station. All stems (tree + palm) with diameter at breast height ≥ 10 cm were recorded, identified and measured. A total of 3040 stems were recorded (tree = 2815; palm = 225), corresponding to 42 botanic families and 140 identified species. Seven families and 20 genera contained unidentified taxa (12.2%). Sapotaceae (735 stems; 10 species), Leguminosae (409; 24) and Rubiaceae (289; 12) were the most abundant families. Peltogyne gracilipes Ducke (Leguminosae), Pradosia surinamensis (Eyma) T.D.Penn. (Sapotaceae) and Ecclinusa guianensis Eyma (Sapotaceae) were the species with the highest importance value index (~ 25%). The dominance (m2 ha-1) of these species corresponds to > 36% of the total value observed in the forest inventory. Our dataset provides complementary floristic and structure information on tree and palm in Maracá, improving our knowledge of this Amazonian ecotone forest.
The Ganoderma weberianum-resinaceum lineage: multilocus phylogenetic analysis and morphology confirm G. mexicanum and G. parvulum in the Neotropics

Many species of Ganoderma exhibit a high phenotypic plasticity. Hence, particularly among them, the morphological species concept remains difficult to apply, resulting in a currently confused taxonomy; as a consequence, the geographical distribution range of many species also remains very uncertain. One of the areas with a strong uncertainty, as far as morphological species concept is concerned, is the Neotropics. It is common that names of species described from other regions, mainly from northern temperate areas, have been applied to Neotropical species. The aim of the present study was to determine which species might lay behind the G. weberianum complex in the Neotropics, using morphological studies and phylogenetic inferences based on both single (ITS) and multilocus (ITS, rpb2, and tef1-α) sequences. The results indicated that G. weberianumsensu Steyaert, which is the usually accepted concept for this taxon, was absent from the Neotropics. In this area, G. weberianumsensu Steyaert encompassed at least two phylogenetic species, which are tentatively, for the time being, identified as belonging to G. mexicanum and G. parvulum. These two species could be distinguished morphologically, notably by the ornamentation or its absence on their chlamydospores. The results also showed that additional species from the Neotropics might still exist, including, e.g., G. perzonatum, but their circumscription remains uncertain until now because of the paucity of material available. Furthermore, it was found that the current concept of G. resinaceum embraced a complex of species.
