Digital radio platforms in the New Zealand context: Implementing The Wireless and iHeartRadio
Authors: McEwan Rufus
Published: January 2018

The recent implementation of two digital platforms by the New Zealand radio industry as a response to contemporary media transformation highlights the ongoing problem of anticipating radio futures. The Wireless has been established by New Zealand’s sole public service radio network and challenges many conventions commonly associated with the radio medium; text-based and video content is prioritized by project staff in the pursuit of a younger audience demographic. An alternative commercial platform, iHeartRadio, combines the collected web streams of participating radio broadcasters with customizable music playlists, legitimizing radio brands in a new media environment. Utilizing semi-structured interviews with radio professionals, in conjunction with an analysis of industry reporting and media coverage of recent radio developments, key findings indicate that the motivations for introducing The Wireless and iHeartRadio are strongly connected to the dynamics of the local industry, demonstrating the role of organizational influence in determining the shape and form of future radio development.
Dust mop or mic? Women’s utopian border-crossings in Cold War ham radio
Authors: Gessler Anne
Published: January 2018

During the 1950s and the 1960s, a wave of technologically inclined women joined the amateur radio community, drawn to its commitment to public service and innovation. However, government, commercial and cultural pressure on amateur radio to justify its existence forced the predominantly male hobby to police its borders against female incursions. Countering a domestic containment ideology that positioned male hams as wage-earning husbands and national defenders inhabiting the public sphere, and female hams as housewives confined within the private sphere, women promoted a cosmopolitan, technocratic vision of radio’s capacity to foster a progressive society unencumbered by outmoded gender expectations. Women’s QSL cards (postcards exchanged to confirm on-air communication) map an international social network of likeminded women at a moment in which they were ignored and maligned. By designing their own cards, women recuperated sexist visual tropes to define their own gender identities and behaviours. They constituted physical proof of the technical expertise of female amateurs and documented their participation in radio organizations and public-minded activities. Finally, the cards facilitated female solidarity critical to rooting out sexism in the Cold War-era ham community. Examining the strategies of female hams for contesting institutionalized sexism helps us understand how women create community and foster understanding in male-dominated fields.
Generalized null 2-type immersions in Euclidean space
Authors: Lee Jae Won , Kim Dong-Soo , Kim Young Ho , Yoon Dae Won
Published: January 2018

We define generalized null 2-type submanifolds in the m-dimensional Euclidean space 𝔼
m
. Generalized null 2-type submanifolds are a generalization of null 2-type submanifolds defined by B.-Y. Chen satisfying the condition Δ H = f H + gC for some smooth functions f, g and a constant vector C in 𝔼
m
, where Δ and H denote the Laplace operator and the mean curvature vector of a submanifold, respectively. We study developable surfaces in 𝔼3 and investigate developable surfaces of generalized null 2-type surfaces. As a result, all cylindrical surfaces are proved to be of generalized null 2-type. Also, we show that planes are the only tangent developable surfaces which are of generalized null 2-type. Finally, we characterize generalized null 2-type conical surfaces.
On the real differential of a slice regular function
Authors: Altavilla Amedeo
Published: January 2018

In this paper we show that the real differential of any injective slice regular function is everywhere invertible. The result is a generalization of a theorem proved by G. Gentili, S. Salamon and C. Stoppato and it is obtained thanks, in particular, to some new information regarding the first coefficients of a certain polynomial expansion for slice regular functions (called spherical expansion), and to a new general result which says that the slice derivative of any injective slice regular function is different from zero. A useful tool proven in this paper is a new formula that relates slice and spherical derivatives of a slice regular function. Given a slice regular function, part of its singular set is described as the union of surfaces on which it results to be constant.
Minimising Backbreak at the Dewan Cement Limestone Quarry Using an Artificial Neural Network
Authors: Muhammad Khan , Shah Akram
Published: January 2018

Backbreak, defined as excessive breakage behind the last row of blastholes in blasting operations at a quarry, causes destabilisation of rock slopes, improper fragmentation, minimises drilling efficiency. In this paper an artificial neural network (ANN) is applied to predict backbreak, using 12 input parameters representing various controllable factors, such as the characteristics of explosives and geometrical blast design, at the Dewan Cement limestone quarry in Hattar, Pakistan. This ANN was trained with several model architectures. The 12-2-1 ANN model was selected as the simplest model yielding the best result, with a reported correlation coefficient of 0.98 and 0.97 in the training and validation phases, respectively. Sensitivity analysis of the model suggested that backbreak can be reduced most effectively by reducing powder factor, blasthole inclination, and burden. Field tests were subsequently carried out in which these sensitive parameters were varied accordingly; as a result, backbreak was controlled and reduced from 8 m to less than a metre. The resulting reduction in powder factor (kg of explosives used per m3 of blasted material) also reduced blasting costs.
Long-Term Planning for Open Pits for Mining Sulphide-Oxide Ores in Order to Achieve Maximum Profit
Authors: Kržanović Daniel , Conić Vesna , Stevanović Dejan , Kolonja Božo , Vaduvesković Jovan
Published: January 2018

Profitable exploitation of mineralised material from the earth’s crust is a complex and difficult task that depends on a comprehensive planning process. Answering the question of how to plan production depends on the geometry of the deposit, as well as the concentration, distribution, and type of minerals in it. The complex nature of mineral deposits largely determines the method of exploitation and profitability of mining operations. In addition to unit operating costs and metal prices, the optimal recovery of and achievement of maximum profit from deposits of sulphide-oxide ores also depend, to a significant extent, on the level of technological recovery achieved in the ore processing procedure. Therefore, in defining a long-term development strategy for open pits, special attention must be paid to the selection of an optimal procedure for ore processing in order to achieve the main objective: maximising the Net Present Value (NPV). The effect of using two different processes, flotation processing and hydrometallurgical methods (bioleaching acid leaching), on determining the ultimate pit is shown in the case of the Kraku Bugaresku-Cementacija sulphide-oxide ore deposit in eastern Serbia. Analysis shows that the application of hydrometallurgical methods of processing sulphide-oxide ore achieved an increase in NPV of 20.42%.
Characteristics of the Roof Behaviors and Mine Pressure Manifestations During the Mining of Steep Coal Seam
Authors: Hong-Sheng Tu , Shi-Hao Tu , Cun Zhang , Lei Zhang , Xiao-Gang Zhang
Published: January 2018

A steep seam similar simulation system was developed based on the geological conditions of a steep coal seam in the Xintie Coal Mine. Basing on similar simulation, together with theoretical analysis and field measurement, an in-depth study was conducted to characterize the fracture and stability of the roof of steep working face and calculate the width of the region backfilled with gangue in the goaf. The results showed that, as mining progressed, the immediate roof of the steep face fell upon the goaf and backfilled its lower part due to gravity. As a result, the roof in the lower part had higher stability than the roof in the upper part of the working face. The deformation and fracture of main roof mainly occurred in the upper part of the working face; the fractured main roof then formed a “voussoir beam” structure in the strata’s dip direction, which was subjected to the slip- and deformation-induced instability. The stability analysis indicated that, when the dip angle increased, the rock masses had greater capacity to withstand slip-induced instability but smaller capacity to withstand deformation-induced instability. Finally, the field measurement of the forces exerted on the hydraulic supports proved the characteristics of the roof’s behaviors during the mining of a steep seam.
Comparative Experiment Study on Nitrogen Injection and Free Desorption of Methane-Rich Bituminous Coal Under Triaxial Loading
Authors: Zhang Lei , Ye Zhiwei , Tang Jun , Hao Dingyi , Zhang Cun
Published: January 2018

As a kind of associated geological gas, coalbed methane (CBM) is mainly adsorbed in the coal seam. The coal-methane adsorption phenomenon can be described by Langmuir monolayer adsorptio n model, BET multilayer adsorption model and the Theory of Volume Filling of Micropore (TVFM), whereas the binary gas adsorption phenomenon can be described by the extended Langmuir Model. For the CBM in the low permeability coal seam, the amount of gas released by direct drainage is relatively limited, which cannot eliminate the gas explosion and outburst hazards. Gas injection is an effective method to promote methane drainage. In this paper, the free desorption and nitrogen injection displacement experiments are comparatively analyzed, which allows verifying the effectiveness of nitrogen injection’s enhancement to gas drainage. The experiment of injecting nitrogen gas into the coal body shows that the coal fracture can be maintained or expanded by the injected gas pressure so that more methane can be released. The nitrogen injection has a higher time efficiency than that of free desorption as well. The displacement ratio of N2/CH4 is in the range of 1-3. Both the injection pressure and confining pressure affect the displacement ratio. The analysis of the desorbed gas components shows that the relationship between the methane component and gas flooding time is an “inverted S” shape curve, and the appropriate time for the methane collection can be inferred by the time interval of the rapid decline of the curve.

Multi-Objective Optimization of Acoustical Properties of PU-Bamboo-Chips Foam Composites
Authors: Jiang Yang , Chen Shuming , Wang Dengfeng , Chen Jing
Published: January 2018

In this study, an effective optimization approach was proposed to improve acoustical behaviors of PU foams. The important parameters of PU foams: content of water, silicone oil and catalyst A1 were chosen and their effects on sound absorption coefficient and transmission loss of PU foams were studied by using Taguchi methods. In addition, bamboo chips were incorporated into PU foams as fillers to improve the acoustical properties of PU foams. Four controlled factors: the content of water, silicone oil, catalyst A1 and bamboo chips with three levels for each factor were chosen and Taguchi method based on orthogonal array L9(34) was employed to conduct the experiments. Based on the results of Taguchi’s orthogonal array L9(34), signal-to noise (S/N) analysis was used and developed to determine an optimal formulation of PU-bamboo-chips foam composites.
Spectral Properties of Circular Piezoelectric Unimorphs
Authors: Pustka Martin , Půst Ladislav
Published: January 2018

The piezoelectric unimorphs are essential resonant components of many oscillating systems including electroacoustic devices. The unimorph spectral properties are namely dependent on geometric dimensions, applied materials and mounting. Preliminary dimensioning and optimization of unimorph shape are usually carried out prior to comprehensive design work mostly based on finite element method. Simple analytical model is a suitable tool for initial design phase. This paper presents a derivation of calculation model describing natural vibrations of a circular unimorph with the piezoelectric layer diameter smaller than the elastic layer diameter. The system of equations with closed-form solution is instrumental to calculation of resonant frequencies and mode shapes for unimorphs with clamped, simply supported and free circumference. The theoretical results are compared with vibration velocity measurement of clamped unimorph sample in a wide frequency range. Analytical model derived in this paper is used to assess the effect of the thickness tolerance on unimorph resonant frequencies.
Determination of Regional Presence of Male Body Types as a Prerequisite for Improving Garment Manufacture
Authors: Doležal Ksenija , Hrženjak Renata , Ujević Darko
Published: January 2018

Garment manufacture and garment fit to physique is a never-ending research subject. The human body is subject to changes that are reflected in its shape and body measurements, and appear in all periods of life. Monitoring the changes and gaining insight into the actual amounts of physical dimensions of an individual population unfold numerous opportunities to affect clothing design and manufacturing. In accordance with the issues mentioned above, a research was carried out to determine male body types of the Croatian male population. Male body types for a specific clothing size determine waist and hip girth, which completes the information on main body measurement amounts. Furthermore, the types of bodies are prescribed by the European Standard 14302-3 and, accordingly, in the observed sample, the presence of a particular type is determined with respect to regional affiliation and age. This study was conducted on a sample of 4090 test subjects divided into five regions, ages 20 to 85 years, divided into seven age groups. By statistical analysis of the results, that is, by the methods of descriptive statistics, the values of physical dimensions necessary for this research were determined.
Effects of Processing Parameters on the Mechanical Properties of Aramid Air Textured Yarns for Protective Clothing
Authors: Kim Hyun Ah , Kim Seung Jin
Published: January 2018

This study examined the mechanical properties of a para-aramid filament according to the processing conditions of air-jet textured yarns (ATY). The specimens were prepared by changing the yarn speed, over feed ratio, air pressure, and heater temperature, which are important processing factors in the ATY process. The basic physical properties of the ATY, such as denier, tenacity, breaking strain, and initial modulus, were measured and their thermal shrinkage, such as dry and wet shrinkage, were measured to determine the thermal stability of the aramid ATY. In addition, the instability of para-aramid ATY were measured and assessed with the loop formation of ATY, according to the ATY process parameters. An examination of the effects of process parameters on the physical properties of aramid ATY revealed the core overfeed and air pressure to be the main factors. A high core overfeed and air pressure make the aramid ATY crimpy in the yarn core and entangle the fluffy loops on the yarn surface, resulting in an increase in the yarn linear density and breaking strain as well as a decrease in the tenacity and initial modulus. In contrast, these yarn physical properties were unaffected by the yarn speed, heater temperature, and wetting treatment. In addition, the dry and wet thermal shrinkage were unaffected by the process parameters of ATY. On the other hand, the instability decreased with increasing core overfeed and heater temperature and increased with increasing air pressure. These results showed that a high core overfeed makes the aramid ATY crimpy with an entangled yarn structure, and high air pressure helps provide small loops on the yarn surface. Finally, a high heater temperature makes the crimpy ATY structure more stable due to the strong heat set, which results in low instability.
Dissecting the act of god: an exploration of the effect of religiosity on economic activity
Authors: Carpantier Jean-Francois , Litina Anastasia
Published: January 2018

This research explores whether religiosity has a persistent effect on economic outcomes. We follow a three-step analysis. First, we use a sample of migrants in the United States to establish that religiosity in the country of origin has a lasting effect on the religiosity of migrants. Second, by exploiting variation in the inherited component of religiosity of migrants and controlling only for a baseline set of controls, we uncover a causal link between several aspects of religiosity and income level. The empirical findings of the second step suggest that i) church attendance has a positive impact on income; and ii) stronger faith is associated with a higher income. Finally, we augment the set of controls included in the measure of inherited religiosity in order to capture the effects of social capital, education, and of traits conducive to income growth. When controlling for social capital, the effect of religious attendance on economic outcomes vanishes, and when controlling for the presence of traits conducive to growth, the effect of intensity of faith vanishes as well. We therefore conclude that when properly accounting for unobservables, religiosity does not affect per capita income.

Published: January 2018

Relative to that of sponges, the diversity of fungi associated with corals, and their ecological roles, remain largely unknown. In this study, we surveyed culturable diversity and screened antimicrobial activity of spent culture liquid of fungi associated with five scleractinian corals collected in the South China Sea. In total, 123 fungal isolates were obtained, which were identified to 31 taxa in 23 genera from two phyla (Ascomycota and Basidiomycota) by comparing their ITS rDNA sequences with the reference sequences in GenBank. Specifically, eight genera of the Ascomycota (Periconia, Arthrinium, Engyodontium, Lasiodiplodia, Hortaea, Devriesia, Cyphellophora and Cadophora) and six genera of the Basidiomycota (Rhodosporidium, Panus, Trametes, Schizophyllum, Trichosporon and Cystobasidium) are new records for corals. The fungal communities in the five scleractinian coral species, together with those from previous studies, indicate that a high level of fungal diversity is associated with scleractinian corals. The antimicrobial activities of spent culture liquid of 31 selected fungal species were tested against five marine pathogenic bacteria. This study contributes to our knowledge of scleractinian coral-associated fungi and their potential as sources of pharmaceutical drug leads for pathogenic bacteria.
Auxin-like compounds act as protectors against UV-B irradiation in garden pea plants
Authors: Sergiev Iskren , Todorova Dessislava , Shopova Elena , Katerova Zornitsa , Jankauskienė Jurga , Jurkonienė Sigita
Published: January 2018

Pretreatment with the original auxin physiological analogues 1-[2-chloroethoxycarbonylmethyl]-4-naphthalenesulfonic acid calcium salt (TA-12) and 1-[2-dimethylaminoethoxicarbonylmethyl]naphthalene chlormethylate (TA-14) and subsequent UV-B irradiation (180 min at λmax 312 nm for 6.6 kJ·m−2) of pea plants (Pisum sativum L.) was investigated to assess if foliar application of these compounds has ability to attenuate the negative effects caused by UV-B stress. UV-B treatment increased malondialdehyde (MDA) and proline levels as well as superoxide dismutase, catalase and guaiacol peroxidase activities, but decreased hydrogen peroxide, low-molecular thiols, total phenolics and total soluble protein contents. The pre-treatment with TA compounds decreased the oxidative stress provoked by UV-B radiation detected by lower level of MDA, increased the content of thiols and UV-absorbing compounds and had favourable effect on H2O2 content and enzymatic activities. Exogenous application of auxin-like compounds on pea plantlets successfully counteracted UV-B induced oxidative stress via activation of ROS detoxifying enzymes and non-enzymatic antioxidants.
Notes on the enigmatic Thesium linophyllon and report on Thesium ramosum in Lithuania
Authors: Gudžinskas Zigmantas , Žalneravičius Egidijus
Published: January 2018

Two species of the genus Thesium (T. ebracteatum and T. linophyllon) are constantly recognized as members of the flora of Lithuania. However, the study on plants currently occurring in Lithuania and usually identified as T. linophyllon revealed that in fact they belong to T. ramosum. The analysis of all available data on the occurrence of T. linophyllon in Lithuania indicated that this species has never been recorded. The report on the occurrence of T. linophyllon, published at the end of the 18th century, was based on misidentified T. ebracteatum. Thus, T. linophyllon should be excluded from the list of vascular plants of Lithuania. Occurrence of T. ramosum was reported for the first time in the country. Currently, one population of this species with two subpopulations are known in the environs of Varnikai village (Trakai distr., Trakai Historical National Park). Morphological description of T. ramosum and diagnostic features of this species were provided. The structure and habitat conditions of two subpopulations were investigated in 2017. The present population of this species was revealed to consist of 52 individuals. Occurrence of young individuals in one subpopulation indicates generative reproduction of T. ramosum. Negative relationship between the number of T. ramosum individuals and the coverage of Poaceae species, and positive relationship between the coverage of Fabaceae species were revealed. Localities of T. ramosum in Lithuania are far from the area of its native distribution, and this species is ascribed to the group of established alien species. Further spread and invasion of the species is not expected.
The Evolution of Financial Integration on Selected European Stock Markets: a Dynamic Principal Component Approach
Authors: Majewska Elżbieta , Olbryś Joanna
Published: January 2018

The goal of this paper is to recognize the dynamics of financial integration across the European stock markets over the last two decades. We investigate two groups of markets: (1) three developed European markets in the U.K., France, and Germany; and (2) three emerging Central and Eastern European markets in Poland, the Czech Republic, and Hungary (CEE–3). The evolution of the integration process is analyzed using a dynamic principal component approach. The index of integration serves as a robust measure of integration. The empirical results reveal that the dynamics of integration across the whole group of markets increased significantly following the CEEC–3’s accession to the European Union. An inverted U‑shape in the index of integration has been found in this case. Moreover, the average index of integration was significantly different during the Global Financial Crisis compared to the pre‑crisis period.
Effects of Poland’s Pro‑Export Policy Implementation in the Context of the Plan for Responsible Development – a Preliminary Comparative Assessment
Authors: Wysokińska Zofia
Published: January 2018

The aim of this paper is to present the results of a preliminary assessment of Poland’s export expansion policy in relation to the export of commodities, which is a result of the Government’s Plan for Responsible Development, in the context of existing barriers and the external and internal conditions reported by small and medium‑sized enterprises sector (SMEs). In the latest ranking of its competitive position in the global market for the period 2016–2017, Poland ranked 36th in the world. It should also be stressed that in this most recent world ranking Poland held the 16th position among EU Member States. A positive phenomenon in relation to Poland’s foreign trade in 2016, as compared to previous years, was that the value of export exceeded import, which allowed for a turnover surplus of nearly EUR 4.8 billion, i.e. two times higher than in 2015. In 2016 (and also in the first half of 2017) there was a favorable diversification of Polish export, demonstrating an increase in export to non‑EU markets of economically developed countries. After two years of relatively slow growth, export to this group of countries in 2016 increased by 5.6% (to EUR 12 billion), i.e. nearly 2.5 times faster than the total export. Despite the tariff‑free and quota‑free access to the single European market, there are still limits and barriers to the free movement of goods, and especially services. There are also many internal barriers in small and medium‑sized enterprises’ export to foreign markets, which limit their export expansion. Despite the gradual increase in export observed in recent years, the internationalization of non‑Polish enterprises is still much lower than in Western European countries. As a result, the share of Polish SMEs in the EU market is one third smaller than the EU average.
Corporate Social Responsibility: the Challenges and Constraints
Authors: Piasecki Ryszard , Gudowski Janusz
Published: January 2018

This article discusses the chances and vulnerabilities of corporate social responsibility (CSR) on two main levels: the small and medium sector at a local level; and big corporations at the macro and international levels. The modern understanding of the definition of CSR is also analyzed. This concept in the management sciences is often misunderstood because it is usually seen as one means in the struggle to achieve a better competitive position. On the other hand, for the development sciences CSR is an effective instrument of income redistribution and as an addition to state support for the underprivileged social groups.
Morphological and genetic characterization of vine grape cultivars of Herzegovina
Authors: Knezović Zrinka , Mandić Ana , Perić Nikica , Beljo Jure , Mihaljević Maja Žulj
Published: January 2018

In Herzegovina, different genotypes of grapevine are called the same, and the origin of these cultivars is mainly unexplored. Two groups of autochthonous cultivars are grown. The first group consists of more widespread Žilavka and Blatina, and accompanying Bena, Krkošija, Dobrogostina and Trnjak, and the second one of less common cultivars that should be preserved from extinction. Considering the small number of studies on the comparison of different methods used for analyses of similarities and relatedness of grapevine germplasm, it was interesting to assess the use of morphological characterization with molecular markers in identification of cultivars in Herzegovina. The results indicate that a similarity coefficient had a broad value range for both methods. Both methods successfully in different ways differentiated all analysed varieties, and for complete and comprehensive identification of grapevine varieties should be use.

Selected Constituent Yield Variation in the Smoke of Commercial Cigarette Brands on the Japanese Market
Authors: Hyodo Takatsugu
Published: January 2018

This study focused on the variation in the yields of constituents in smoke from commercial cigarette brands available on the Japanese market. Nineteen commercial cigarette brands were sampled five times every two months from 2009 to 2010. The target constituents were benzo[a]-pyrene, 1,3-butadiene, benzene, formaldehyde, acetaldehyde, acrolein, N-nitrosonornicotine (NNN), 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), carbon monoxide, “tar”, and nicotine. The results of this study showed that the coefficient of variation (CV) values varied greatly by brands, constituents, and smoking regimes. The yields of NNN and NNK in the smoke were strongly correlated to their yields in the tobacco filler blend for most brands. The yields of benzo[a]pyrene under the International Organization for Standardization (ISO) and the Health Canada Intense (HCI) smoking regimes and 1,3-butadiene under the HCI smoking regime were found to be influenced by the measurement. It was shown that factors for variation were highly varied among constituents. The grand mean of CV values for NNN and formaldehyde associated with cigarette manufacturing over ten months and measurement at the JT laboratory under the HCI smoking regimes were 17.1% and 6.6% respectively. The grand mean of CV values for NNN and formaldehyde associated with both cigarette manufacturing over ten months and measurement at different laboratories under the HCI smoking regimes were 23.7% and 22.9% respectively. This is due to the fact that formaldehyde showed the highest CV values for reproducibility among the constituents. Thus, in order to set realistic and robust confidence intervals, it is very important to take into account the variations associated with cigarette manufacturing and measurement within and between laboratories.

Opportunistic Protozoan Infections of Carnivores
Authors: Mravcová K. , Ferko M. , Štrkolcová G. , Goldová M.
Published: January 2018

Giardiasis and cryptosporidiosis are protozoan infections of the digestive tract and one of the most frequent causes of enteritis in dogs and cats, associated with acute and chronic diarrhoea. Generally, the risk of infection is higher for younger individuals in which the overall clinical picture and the course of disease are more serious. In this study we investigated the prevalence of giardiasis and cryptosporidiosis in dogs in Košice district of eastern Slovakia. From September 2015 until November 2016, we examined samples of faeces from 100 dogs from two shelters. Giardia duodenalis was diagnosed by the flotation method according to Faust, and by the molecular biologic method (Nested PCR). For the diagnosis of cryptosporidium oocysts, we used a staining method according to Kinyoun, and for detection of the presence of Cryptosporidium spp. a sandwich ELISA method. The total prevalence of these protozoan infections were 22 % (22/100), and of that, 19 % of the samples (19/100) were positive for Giardia duodenalis and 3 % (3/100) for the Cryptosporidium spp. In the shelter in Haniska, the giardia cysts were present in 9/54 samples (16.6 %) and cryptosporidia oocysts in 1/54 (1.85 %) samples of the faeces. In the Malá Farma shelter, 10/46 (21.73 %) samples were positive for G. duodenalis and 2/46 (4.34 %) showed positivity for Cryptosporidium spp.
Land consolidation in mountain areas. Case study from southern Poland
Authors: Janus Jarosław , Łopacka Magdalena , John Ewa
Published: January 2018

Land consolidation procedures are an attempt to comprehensively change the existing spatial structure of land in rural areas. This treatment also brings many other social and economic benefi ts, contributing to the development of consolidated areas. Land consolidation in mountain areas differs in many respects from those implemented in areas with more favorable conditions for the functioning of agriculture. The unfavorable values of land fragmentation indices, terrain conditions and lower than the average soil quality affect both the dominant forms of agricultural activity and the limited opportunities to improve the distribution of plots in space, parameters of shape, and the area as a result of land consolidation. For this reason, the effectiveness of land consolidation in mountain areas can be achieved by improving the quality of transportation network and the accessibility of the plots, arranging ownership issues and improving the quality of cadastral documentation. This article presents the evaluation of the measures of effectiveness of land consolidation realized in mountain areas on the example of Łetownia Village in the Małopolska Province, located in the southern part of Poland. Selected village is an area with unfavorable conditions for the functioning of agriculture and high values of land fragmentation indices.
New approach to isometric transformations in oblique local coordinate systems of reference
Authors: Stępień Grzegorz , Zalas Ewa , Ziębka Tomasz
Published: January 2018

The research article describes a method of isometric transformation and determining an exterior orientation of a measurement instrument. The method is based on a designation of a “virtual” translation of two relative oblique orthogonal systems to a common, known in the both systems, point. The relative angle orientation of the systems does not change as each of the systems is moved along its axis. The next step is the designation of the three rotation angles (e.g. Tait-Bryan or Euler angles), transformation of the system convoluted at the calculated angles and moving the system to the initial position where the primary coordinate system was. This way eliminates movements of the systems from the calculations and makes it possible to calculate angles of mutual rotation angles of two orthogonal systems primarily involved in the movement. The research article covers laboratory calculations for simulated data. The accuracy of the results is 10-6 m (10-3 regarding the accuracy of the input data). This confi rmed the correctness of the assumed calculation method. In the following step the method was verifi ed under fi eld conditions, where the accuracy of the method raised to 0.003 m. The proposed method enabled to make the measurements with the oblique and uncentered instrument, e.g. total station instrument set over an unknown point. This is the reason why the method was named by the authors as Total Free Station - TFS. The method may be also used for isometric transformations for photogrammetric purposes.

Propagation of uncertainty by Monte Carlo simulations in case of basic geodetic computations
Authors: Wyszkowska Patrycja
Published: January 2018

The determination of the accuracy of functions of measured or adjusted values may be a problem in geodetic computations. The general law of covariance propagation or in case of the uncorrelated observations the propagation of variance (or the Gaussian formula) are commonly used for that purpose. That approach is theoretically justified for the linear functions. In case of the non-linear functions, the first-order Taylor series expansion is usually used but that solution is affected by the expansion error. The aim of the study is to determine the applicability of the general variance propagation law in case of the non-linear functions used in basic geodetic computations. The paper presents errors which are a result of negligence of the higher-order expressions and it determines the range of such simplification. The basis of that analysis is the comparison of the results obtained by the law of propagation of variance and the probabilistic approach, namely Monte Carlo simulations. Both methods are used to determine the accuracy of the following geodetic computations: the Cartesian coordinates of unknown point in the three-point resection problem, azimuths and distances of the Cartesian coordinates, height differences in the trigonometric and the geometric levelling. These simulations and the analysis of the results confirm the possibility of applying the general law of variance propagation in basic geodetic computations even if the functions are non-linear. The only condition is the accuracy of observations, which cannot be too low. Generally, this is not a problem with using present geodetic instruments.

Background:

Ghrelin, leptin and insulin, generally considered as regulators of energy homeostasis of the organism may be related to fetal and early postnatal growth. Numerous studies have confirmed the presence of these hormones in the cells of the fetus indicating their importance in development at early stages of life.

Methods:

This study analyzed active and total ghrelin by radioimmunoassay (RIA), leptin and insulin concentrations by enzyme-linked immunosorbent assay (ELISA) in 65 cord blood samples, from term newborns, and measured the birth anthropometric parameters [birth weight (BW), head circumference, chest, stomach, thigh and arm circumference].

Results:

Active ghrelin (AG) concentrations correlated negatively with BW, head circumference, stomach and thigh circumference. When divided by gender, AG correlated negatively with males’ BW, stomach and thigh circumference. Females’ head circumference correlated negatively with AG. Cord leptin correlated positively with arm circumference. When divided by gender, cord leptin was positively associated with BW and stomach circumference in male newborns and with thigh and arm circumference in female newborns. Insulin concentrations tended to correlate positively with BW in male newborns.

Conclusions:

In summary, it was confirmed that cord blood ghrelin, leptin and insulin correlate with anthropometric parameters at birth. This study showed a negative correlation of AG with anthropometric parameters, which may emphasize that this hormone is an indicator of growth restriction. This is in contrast to cord leptin and insulin, which are more connected with overgrowth. Taking all the results into consideration, the metabolic status of the fetus and newborn is an essential component in understanding the regulation of perinatal development.
Building Virtual Reality Applications for Engineering with Knowledge-Based Approach
Authors: Górski Filip
Published: January 2018

The paper presents a novel methodology of building industrial Virtual Reality applications with use of a knowledge-based approach. Virtual Reality is becoming more and more wide-spread in engineering applications. However, most solutions are immediate and not flexible, especially in maintenance. Traditional way of programming VR applications makes all the knowledge about a product or a process hard-coded, effectively losing access to it from the outside of the programming software. Besides, making new solutions without any methodology whatsoever makes the process longer and less effective. The author proposes to use general rules of available Knowledge Engineering methodologies in order to make the process of building VR applications more effective and to ensure their flexibility and access to stored knowledge, even after an application is deployed. The presented methodology is supported with practical case studies.
Justification of RFID Implementation. A Case Study of White Goods Manufacturer
Authors: Gladysz Bartlomiej , Nalepa Katarzyna , Santarek Krzysztof
Published: January 2018

Radio Frequency Identification (RFID) is a rapidly emerging technology with a wide range of impact and still not fully exploited potential applications. The impact of RFID is not limited to the area of its direct application. There are many possible benefits to be gained from RFID application, but it must be preceded with careful analysis as its implementation is not always reasonable. A new method for an assessment of RFID technology was presented and explained on the case of a white goods manufacturer. There was a lack of such a method allowing for relatively quick and flexible assessment, which is important for decision makers, who do not want to become involved in very sophisticated and time-consuming analysis at the early stage of decision making. The method supports early phases of decision making related to RFID implementation. Conclusions derived from the analysis of the case study confirmed that the method applied allows for rationalizing decision making and answers whether RFID could generate strategic advantage, in which area RFID should be applied, how RFID-supported processes will be executed and what benefits would be expected. previous papers focused only on answering specific questions from the above list, without showing a holistic approach. the approach to answer questions about execution of processes and benefits was not considered earlier at all. The paper illustrates details of using a new method of an assessment of RFID technology (ART) using a real industrial example.
“Gallia and Gaul, French and Welsh” (MWW, 3.1.89): Transposing Shakespeare’s ‘Favourite’ Foreign Accents into French
Authors: Lacroix Mylène
Published: January 2018

The Merry Wives of Windsor has long been compared to a great babel of languages. The play contains a smattering of Spanish, Italian and Dutch and even a whole scene dedicated to the mistranslation of Latin. A large part of the play’s humour also heavily relies on the foreign accents of two characters: the French Doctor Caius and the Welsh parson Sir Hugh Evans. If Christopher Luscombe’s 2008/2010 production of The Merry Wives at Shakespeare’s Globe theatre in London bears testimony to the success of cross-language and accent-based comedy as a source of laughter on today’s English stage, it seems rather implausible, at first sight, that French translations, adaptations and stagings of these accents and linguistic idiosyncrasies should be greeted with the same degree of hilarity. Indeed, how should the Welsh and French accents, both representing real stumbling blocks for French-speaking translators of the play, be transposed into French? What translation strategies can the latter devise? And to what extent can some of those strategies be said to be politically correct? Focusing on Shakespeare’s ‘favorite’ (predominant) accents and the significance and impact of such linguistic comedy, I shall examine the question of their problematic translation through the analysis and comparison of a number of translations and stagings of The Merry Wives of Windsor into French.
