Jeszcze o odróżnianiu określeń temporalnych deiktycznych od wyznaczających narracyjnie (anaforycznych)

Again on distinguishing deictic from anaphoric temporal expressions

The paper discusses two series of temporal expressions in Polish: one that localizes the described event with regard to the act of speech (the deictic series), and one, used in narratives, that localizes it with regard to a fixed point (the so-called anaphoric series). Both series indicate simultaneity, anteriority, or posteriority of the event with regard to the act of speech (Pol. dziś ‘today’, wczoraj ‘yesterday’, tydzień temu ‘a week ago’, jutro ‘tomorrow’, za tydzień ‘in a week’, and others), or with respect to a fixed point (tego dnia ‘that day’, w przeddzień ‘a day before’, w poprzednim tygodniu ‘a week before’, nazajutrz ‘the day after’, w następnym tygodniu ‘a week later’). The two series differ in certain syntactic grammatical properties, e.g. connectivity with tense forms of the described verbs; cf. the impossible *Jutro byłem ‘I was tomorrow’, and the possible, when talking about the past, Nazajutrz byłem ‘I was a day after’. The anaphoric series, being semantically more general, can usually appear in deictic contexts; the opposite is not true, cf. the impossible *Tego dnia był w Krakowie, a jutro pojedzie do Zakopanego ‘He was in Cracow that day, and he will go to Zakopane tomorrow’.

The importance of Roman Laskowski’s works for the study of acquisition of Polish outside of Poland, and of Polish-foreign bilingualism

The paper discusses those of Roman Laskowski’s works which touch upon the acquisition of Polish as an ethnic language, by Polish children in Sweden. These children are bilingual because they speak both Polish and Swedish. In his 2009 monography, Laskowski first presents their Polish-Swedish bilingualism, then gives a general description of their Polish, and finally focuses on an analysis of the process of acquisition of grammatical cases as a central category of Polish. The importance of Laskowski’s publications is defined by the fact that they are, so far, only such works about the acquisition of Polish outside of Poland. Laskowski is to be counted among the pioneers of research into Polish-foreign bilingualism.
Powinność i obowiązek

Published: June 2015

Duty and obligation

The interest of the author is in the tangled fates of two synonymous, and partially univocal words in the title: powinność ‘duty’ and obowiązek ‘obligation’. The author follows the two words’ quantitatively and semantically different, but always interwoven presence in the history of the Polish language, using dictionary data and, for contemporary times, data from the National Corpus of Polish. After an initial predominance of powinność, from the 18th century on, obowiązek takes the lead quantitatively, while powinność gradually becomes more clearly linked with the meaning of ‘serious internal moral obligation’ and formal language, leaving to obowiązek mainly the field of legal and administrative duties, and thereby the official style. Nonetheless, a complete semantic and stylistic separation of these two synonymous words has not as yet happened.

Sandhi – non-sandhi. Phonetic-phonological boundary signals of morphological units in Polish

The paper is devoted to those morphonological and phonetic phenomena that may aspire to the role of indicators of stronger morphological boundaries in Polish. The author is inclined towards H. Andersen’s view, whose definition of sandhi as a conventionalized phenomenon excludes a series of surface phenomena and, effectively, includes no more than the so-called voicing sandhi.
Rozgraniczenie jako ograniczenie

Delimitation as a limitation. Research into the word order of the adjectival modifier in contemporary Polish

The article examines the problem of migration of so-called classificatory adjectives in modern Polish, that can be used both pre- and post-nominally in NPs, such as e.g. drukarka atramentowa and atramentowa drukarka ‘ink printer’. It contributes to the discussion initiated by J. Linde-Usiekniewicz (2013), the purpose of which is to verify the results of research into reordering of the constituents of Polish NPs, conducted by Cetnarowska, Pysz, Trugman (2011) and Rutkowski, Progovac (2005). It is claimed that an explanation of this phenomenon must take into account the pragmatic determinant of word order flexibility. A number of facts indicate that the following principles play a crucial role in the reordering of NPs: the iconicity principle, more specifically, the “iconicity of sequence” (or “sequential order”) which holds that a sequence of forms conforms to the sequence of experience and, in this particular case, the hierarchical categorization; and the principle of presumed absorption which shows a strong correlation between the adjectival sequences in NPs and the presence of the evaluative predicative, for example nowoczesna drukarka atramentowa vs. nowoczesna atramentowa drukarka ‘modern ink printer’.

A comment on the term “functional expressions”

The goal of the paper is to verify a set of expressions which should be considered functional. Accepting M. Grochowski’s 1997 general characterization of functional expressions relating to the semanticsyntactic plane, the present author also upholds, from 1995, that the term “functional expression” ought to apply as well to expressions which fulfill auxiliary roles in the creation of the formal syntactic structure of utterances. These are those components of multi-word linguistic units which are bereft of individual meaning, and are synonymous with semantically full lexemes belonging to various parts of speech, primarily adverbs, conjunctions, inflected and uninflected relators, but also verbs in so-called periphrastic (verbal-nominal) expressions.
Reaccreditation of non-medical prescribers: maintaining competence
Authors: Caddye Wendy Sarah , Clair-Jones Anja St.
Published: June 2015

There is no systematic and robust method to assess the competence of non-medical prescribers (NMPs) locally or nationally. NMPs have a responsibility to remain up to date with the knowledge and skills to enable them to prescribe competently and safely within their field of expertise. In 2012, the National Prescribing Centre developed a single competency framework for prescribers defining a set of nine dimensions within three domains that can be used to underpin personal responsibility for prescribing. The authors identified validated assessment tools using a literature search, and selected those suitable for mapping against the nine dimensions. It was hoped that trust NMPs could provide evidence of competence covering all three of the framework domains using the chosen tools. Five NMPs used the tools to create a portfolio and audited them for suitability in establishing a robust and credible evidence-led system to evaluate and accredit ongoing competence. Feedback on their ease of use and applicability was sought. Trust NMPs were then invited to a workshop where the evidence was presented and they were asked to comment on, and contribute to, finalising the tools before they were embedded within trust policy.

150 patient experiences with a soft silicone foam dressing
Authors: Bateman Sharon Dawn
Published: June 2015

Pain, malodour and exudate from acute and chronic wounds can be catastrophic to the patient. Excessive exudate results in significant tissue damage to the wound bed and surrounding skin, reduces quality of life, and often requires costly specialist service input. Effective wound assessment and management including appropriate dressing choice is, therefore, paramount to ensure wound healing can take place in a timely manner. This observational evaluation explores 150 ward-based patients who presented with acute and chronic exuding wounds; it examines and evaluates the proposed benefits of the Cutimed® Siltec foam dressing range over a 4-month period in an acute hospital setting. The outcomes of the evaluation were exudate management, maceration reduction, atraumatic application and removal, non-adherence and patient experience. The evaluation highlights not only an overall positive improvement in exudate management and maceration reduction, non-adherence, atraumatic application and removal but also emphasises the importance of a positive patient experience in the wound-care journey.

Published: June 2015

Chronic wound management remains challenging in clinical practice, especially in the presence of bacterial bioburden and slough. To resolve these clinical challenges, it is essential clinicians implement the TIME framework (tissue, inflammation/infection, moisture, edge of wound) as a model of effective wound bed preparation. As a result of advances in technology and wound care therapies, on the market today are products that can help reduce the wound bed clinical challenges recommended by the TIME framework. This article looks at a wound cleansing solution that reduces the wound bed bioburden by breaking down biofilms and debriding slough.

Creating order from chaos: A classificatory approach to retrieval in a local history photographic archive
Authors: Tinker Amanda
Published: June 2015

With the advent of accessible digital technology in the 1990s, image archive collections that were once the sole preserve of the conservator or researcher with white gloves could now be made available to all. Creating digital surrogates offered promise for increasing public access, however, not without considerable challenges in the making. This article recounts and reflects upon how a local authority aimed to make, potentially, 250,000 glass plate negatives in numerous different local history collections generally accessible by scanning and subject indexing. It considers the challenges of providing metadata that would best meet end-user needs in a touch screen public access system and how and why a hierarchical classification scheme was developed to allow productive browsing of these historic collections of everyday life. The photographic archive case study is then revisited through a twenty-first century lens, discussing latest developments and the potential of open source tools for multidimensional access.

Authors: Abdalla Ahmed , Alawad Awad , Abdalla M. Ali Hussein
Published: June 2015

Background: Locally advanced rectal cancer can be down staged by neoadjuvant therapy and the resultant tumor response can be quantified histologically.Objective: This study aimed to assess pathologic response of neoadjuvant chemoradiation in patients with locally advanced rectal cancers treated in Wad Medani Teaching Hospital (WMTH) and National Cancer Institute (NCI), Wad Medani, Sudan.Patients and Methods: A total of 36 consecutive patients with locally advanced rectal cancer that were managed in WMTH and NCI during the period from 2006-2011 were reviewed. Preoperative pelvic radiotherapy was delivered.  The total of 46 Grays were delivered concurrently with 5- fluorouracil (5-FU) on the first and last week of radiation. Total mesorectal excision of the rectal tumour either by anterior or abdominoperineal resections was planned at 6-8 weeks from completion of preoperative treatment. The pathological response to therapy was assessed by histopathology examination of the surgical specimen.Results: Initial clinical staging of patients revealed 58.3% of them were stage T3/T4N2M0 and 41.7% were stage T3N0M0. Down-staging to stage T1/T2N0M0 was found in 36.1% and stages T3N0M0 in 30.6%. No response was seen in 8.3% of cases with stage T3/T4N2M0 while a complete clinical response (no residual) was seen in 25.0%. Complete histological response was observed 13.8%. Positive lymph-nodes metastasis was confirmed in 8.3% of cases.Conclusion: Neoadjuvant chemoradiation is a reasonable option for cases of rectal cancer and deserves further evaluation.
Real-time dissemination of air quality information using data streams and Web technologies: linking air quality to health risks in urban areas / Izvješćivanje o kvaliteti zraka u stvarnom vremenu kontinuiranim prijenosom podataka i web tehnologijama - povezivanje kvalitete zraka sa zdravstvenim rizicima u urbanim sredinama

Published: June 2015

This article presents a new, original application of modern information and communication technology to provide effective real-time dissemination of air quality information and related health risks to the general public. Our on-line subsystem for urban real-time air quality monitoring is a crucial component of a more comprehensive integrated information system, which has been developed by the Institute for Medical Research and Occupational Health. It relies on a StreamInsight data stream management system and service-oriented architecture to process data streamed from seven monitoring stations across Zagreb. Parameters that are monitored include gases (NO, NO2, CO, O3, H2S, SO2, benzene, NH3), particulate matter (PM10 and PM2.5), and meteorological data (wind speed and direction, temperature and pressure). Streamed data are processed in real-time using complex continuous queries. They first go through automated validation, then hourly air quality index is calculated for every station, and a report sent to the Croatian Environment Agency. If the parameter values exceed the corresponding regulation limits for three consecutive hours, the web service generates an alert for population groups at risk. Coupled with the Common Air Quality Index model, our web application brings air pollution information closer to the general population and raises awareness about environmental and health issues. Soon we intend to expand the service to a mobile application that is being developed.

Individual sensitivity to ionising radiation (IR) is the result of interaction between exposure, DNA damage, and its repair, which is why polymorphisms in DNA repair genes could play an important role. We examined the association between DNA damage, expressed as micronuclei (MNi), nuclear buds (NBs), and nucleoplasmic bridges (NPBs) and single nucleotide polymorphisms in selected DNA repair genes (APE1, hOGG1, XRCC1, XRCC3, XPD, PARP1, MGMT genes; representative of the different DNA repair pathways operating in mammals) in 77 hospital workers chronically exposed to low doses of IR, and 70 matched controls. A significantly higher MNi frequency was found in the exposed group (16.2±10.4 vs. 11.5±9.4; P=0.003) and the effect appeared to be independent from the principal confounding factor. Exposed individuals with hOGG1, XRCC1, PARP1, and MGMT wild-type alleles or APEX1, as well as XPD (rs13181) heterozygous showed a significantly higher MNi frequency than controls with the same genotypes. Genetic polymorphism analysis and cytogenetic dosimetry have proven to be a powerful tool complementary to physical dosimetry in regular health surveillance programmes.

An efficient connected dominating set algorithm in WSNs based on the induced tree of the crossed cube
Authors: Zhang Jing , Zhou Shu-Ming , Xu Li , Wu Wei , Ye Xiucai
Published: June 2015

The connected dominating set (CDS) has become a well-known approach for constructing a virtual backbone in wireless sensor networks. Then traffic can forwarded by the virtual backbone and other nodes turn off their radios to save energy. Furthermore, a smaller CDS incurs fewer interference problems. However, constructing a minimum CDS is an NP-hard problem, and thus most researchers concentrate on how to derive approximate algorithms. In this paper, a novel algorithm based on the induced tree of the crossed cube (ITCC) is presented. The ITCC is to find a maximal independent set (MIS), which is based on building an induced tree of the crossed cube network, and then to connect the MIS nodes to form a CDS. The priority of an induced tree is determined according to a new parameter, the degree of the node in the square of a graph. This paper presents the proof that the ITCC generates a CDS with a lower approximation ratio. Furthermore, it is proved that the cardinality of the induced trees is a Fibonacci sequence, and an upper bound to the number of the dominating set is established. The simulations show that the algorithm provides the smallest CDS size compared with some other traditional algorithms.
Computing the Stackelberg/Nash equilibria using the extraproximal method: Convergence analysis and implementation details for Markov chains games
Authors: Trejo Kristal K. , Clempner Julio B. , Poznyak Alexander S.
Published: June 2015

In this paper we present the extraproximal method for computing the Stackelberg/Nash equilibria in a class of ergodic controlled finite Markov chains games. We exemplify the original game formulation in terms of coupled nonlinear programming problems implementing the Lagrange principle. In addition, Tikhonov’s regularization method is employed to ensure the convergence of the cost-functions to a Stackelberg/Nash equilibrium point. Then, we transform the problem into a system of equations in the proximal format. We present a two-step iterated procedure for solving the extraproximal method: (a) the first step (the extra-proximal step) consists of a “prediction” which calculates the preliminary position approximation to the equilibrium point, and (b) the second step is designed to find a “basic adjustment” of the previous prediction. The procedure is called the “extraproximal method” because of the use of an extrapolation. Each equation in this system is an optimization problem for which the necessary and efficient condition for a minimum is solved using a quadratic programming method. This solution approach provides a drastically quicker rate of convergence to the equilibrium point. We present the analysis of the convergence as well the rate of convergence of the method, which is one of the main results of this paper. Additionally, the extraproximal method is developed in terms of Markov chains for Stackelberg games. Our goal is to analyze completely a three-player Stackelberg game consisting of a leader and two followers. We provide all the details needed to implement the extraproximal method in an efficient and numerically stable way. For instance, a numerical technique is presented for computing the first step parameter (λ) of the extraproximal method. The usefulness of the approach is successfully demonstrated by a numerical example related to a pricing oligopoly model for airlines companies.

Published: June 2015

In the paper, the problem of extraction of complex decision rules in simple decision systems over ontological graphs is considered. The extracted rules are consistent with the dominance principle similar to that applied in the dominancebased rough set approach (DRSA). In our study, we propose to use a heuristic algorithm, utilizing the ant-based clustering approach, searching the semantic spaces of concepts presented by means of ontological graphs. Concepts included in the semantic spaces are values of attributes describing objects in simple decision systems
A fuzzy nonparametric Shewhart chart based on the bootstrap approach
Authors: Wang Dabuxilatu , Hryniewicz Olgierd
Published: June 2015

In this paper, we consider a nonparametric Shewhart chart for fuzzy data. We utilize the fuzzy data without transforming them into a real-valued scalar (a representative value). Usually fuzzy data (described by fuzzy random variables) do not have a distributional model available, and also the size of the fuzzy sample data is small. Based on the bootstrap methodology, we design a nonparametric Shewhart control chart in the space of fuzzy random variables equipped with some L2 metric, in which a novel approach for generating the control limits is proposed. The control limits are determined by the necessity index of strict dominance combined with the bootstrap quantile of the test statistic. An in-control bootstrap ARL of the proposed chart is also considered.
Probability timed automata for investigating communication processes
Authors: Piech Henryk , Grodzki Grzegorz
Published: June 2015

Exploitation characteristics behaves as a decreasing valors factor (DVF) which can be connected with degradation processes. It is a structure that consists of independent attributes which represent situations generally connected with a given exploitation factor. The multi-attribute structure contains attributes directly and indirectly referring to the main factor. Attribute states, by definition, can only maintain or decrease their values. Such situations are met in security, reliability, exploitation, fatigues and many complex one-directed or irreversible processes. The main goal refers to protocol security analysis during the realization of the communication run that specifies the assessment of the level of current and oncoming threats connected with cryptography authentication. In the communication run, the operations of different protocols mutually interleave. Our concept is based on the algorithm of attributes correction during exploitation process realization (Blanchet et al., 2008). The monitoring and correcting procedures make it possible to provide forecast information about possible threats on the basis of the structure of the current attribute values.

Published: June 2015

The aim of this study was to investigate the effect of omega-3 supplementation on some haematological parameters like red blood cells (RBC), haemoglobin (Hgb), haematocrit (Hct), white blood cells (WBC), neutrophils (Neu) and lymphocytes (Lym) that may have a direct effect on the performance of athletic horses. Ten regularly trained Standardbred horses (6 geldings and 4 females, 4-5 years old, mean body weight 500 ± 25 kg) were used for the study. They were randomly divided into two groups. The experimental group received an omega-3 dietary supplementation every day for 30 days. The control group received no supplementation. Every 10 days, horses took part in a 1660 metre harness race and blood samples were collected from each horse: one in the morning before race (pre) and one after race (post). The application of one-way analysis of variance for repeated mesures (ANOVA) showed a statistically significant difference due to the race in the two different groups. The results obtained in the present study show a discordant effect of supplementation with omega-3 on RBC, HCT and Hgb, while omega-3 supplementation has been shown to have a better effect on WBC, Neu and Lym, but further studies should be performed to better evaluate the benefits of these on the performance of the athletic horse.
Currency Exchange in an Open-Economy Random Search Model
Authors: Tanaka Mariko
Published: June 2015

This paper studies how endogenous currency exchange arises in a two-country, two-currency monetary search model. Although currency exchange is widely observed in the globalized economy, Zhou (1997) is one of the exceptional studies that adopted a search model to generate currency exchange endogenously. Moreover, in her model, currency exchange occurs only in the case where agents rarely consume foreign goods, which is contrary to the well-known fact that international trade increases the number of currency exchanges. We construct a monetary search model that has a feature that increased international trade increases the volume of currency exchange. We develop a two-country model in which each country has two types of agents: local traders who consume only the goods produced in the home country, and international traders who consume only the goods produced in the foreign country. For international traders, the foreign currency gives more opportunity to obtain the foreign goods than the home currency does. Thus, when an international trader holds the home currency, he has an incentive to exchange the home currency for the foreign currency. Unlike Zhou, the model has a feature that currency exchange is more likely to occur when many agents are engaged in international trade.
Mutation of the conserved GRG motif and
decreasing activity of human RNase H2

Published: June 2015

RNase H2 consists of three subunits (H2A, H2B
and H2C) and is involved in the hydrolysis of RNA/DNA
hybrids. The GRG motif in RNase H2 is highly conserved
and recognizes the ribonucleotides misincorporated into
dsDNA. The mutant G37S in the GRG motif of human RNase
H2A was found to be correlated with Aicardi-Goutièressyndrome
(AGS). In this study, 4 mutants (G37S, G37A,
R38A and G39A) were prepared and their biochemical
properties of secondary structure, activity and binding
affinity with substrate were studied in order to explore the
function of the GRG motif. The activity assay showed that
the mutations resulted in significantly decreased RNase
activity. The binding efficiency assay demonstrated that
binding affinities between 4 mutants and 1-ribo FAMlabeled
substrate were significantly weakened. These
results all indicated that the GRG motif contributes
directly to substrate binding and is closely related to the
enzyme activity.
Piketty’s Capital, His Critics and Basic Income
Authors: Lo Vuolo Rubén M.
Published: June 2015

Among other merits, Piketty’s book puts the topic of inequality and income/wealth concentration in the public agenda. His analysis concludes that aggregate income and wealth have tended to concentrate in the top few percentiles of the population. His research as well as the policy and political debate it has brought about, is relevant for the progress of the Basic Income movement. The tendencies for income and wealth concentration, the importance of inheritance for inequality, the weak foundations of current welfare state institutions, and the relevance of the tax structures for redistribution, all are central themes on the Basic Income debate. In this article, the author discusses certain aspects of Piketty’s
Recognition of amyotrophic lateral sclerosis disease using factorial hidden Markov model
Authors: Khorasani Abed , Daliri Mohammad Reza , Pooyan Mohammad
Published: June 2015

Amyotrophic lateral sclerosis (ALS) is a common disease among neurological disorders that can change the pattern of gait in human. One of the effective methods for recognition and analysis of gait patterns in ALS patients is utilizing stride interval time series. With proper preprocessing for removing unwanted artifacts from the raw stride interval times and then extracting meaningful features from these data, the factorial hidden Markov model (FHMM) was used to distinguish ALS patients from healthy subjects. The results of classification accuracy evaluated using the leave-one-out (LOO) cross-validation algorithm showed that the FHMM method provides better recognition of ALS and healthy subjects compared to standard HMM. Moreover, comparing our method with a state-of-the art method named least square support vector machine (LS-SVM) showed the efficiency of the FHMM in distinguishing ALS subjects from healthy ones.
Specific emitter identification based on graphical representation of the distribution of radar signal parameters
Authors: Dudczyk J. , Kawalec A.
Published: June 2015

The article presents some possibilities of same type radar copies identification with the use of graphical representation. The procedure described by the authors is based on transformation and analysis of basic parameters distribution which are measured by the radar signal especially Pulse Repetition Interval. A radar intercept receiver passively collects incoming pulse samples from a number of unknown emitters. Information such as Pulse Repetition Interval, Angle of Arrival, Pulse Width, Radio Frequency and Doppler shifts are not usable. The most important objectives are to determine the number of emitters present and classify incoming pulses according to emitters. To classify radar emitters and precisely identification the copy of the same type of an emitter source in surrounding environment, we need to explore the detailed structure i.e. intra-pulse information, unintentional radiated electromagnetic emission and fractal features of a radar signal. An emitter has its own signal structure. This part of radar signal analysis is called Specific Emitter Identification. Utilization of some specific properties of electronic devices can cause heightening probability of a correct identification
Metallization of ceramic materials based on the kinetic energy of detonation waves
Authors: Chmielewski T. , Golański D. , Włosiński W.
Published: June 2015

The paper presents an innovatory low-energy detonation-spraying method suitable for the metallization of ceramic materials, in which the energy necessary for joining the metallic coating with the ceramic is delivered in a mechanical way. In the proposed method, the metallic particles, shot from the spraying gun, impinge onto the ceramic substrate with a high velocity, and their kinetic energy is transformed into heat delivered in a specified portion directly to the region of the metal/ceramic joint being formed. The stress distribution and the temperature field at the coating/substrate interface were analyzed also numerically with the aim to optimize the metallization process parameters so as to stimulate the formation of the coating/ceramic joint and, at the same time, to control the region of heat dissipation, the temperature, and the stress state induced in the joint

Published: June 2015

In the study, the mechanical and microstructural properties of friction stir welded EN AW-6060 Aluminum Alloy plates were investigated. The friction stir welding (FSW) was conducted at tool rotational speeds of 900, 1250, and 1500 rpm and at welding speeds of 100, 150 and 180 mm/min. The effect of the tool rotational and welding speeds such properties was studied. The mechanical properties of the joints were evaluated by means of micro-hardness (HV) and tensile tests at room temperature. The tensile properties of the friction stir welded tensile specimens depend significantly on both the tool rotational and welding speeds. The microstructural evolution of the weld zone was analysed by optical observations of the weld zones

This study aimed at the simulation of bone tissue remodeling within a bone defect with the utilization of the finite element method (FEM), enabling - via elaborated application - objective evaluation of orthodontic forces which positively influence periodontium in vivo. The initial position of each bracket on the passive archwire was registered, and then a geometrical and discretemodel of the appliance was created automatically. Assessment of the dental scans obtained using cone beam computed tomography (CBCT) allowed evaluation of the range of bracket displacement: from the initial position to the final one achieved on the active archwire. Those displacements established terminal conditions in the finite element analysis, enabling calculation of orthodontic force levels. An individual design of a tooth with periodontal ligaments and the periodontal defect subsequently loaded with the determined forces allowed simulation of bone remodeling according to Carters adaptation process. Mainly, the bone apposition processes took place in the central part of the periodontal defect, in proximity of the alveolar ridge. However, FEM application in the analysis of bone tissue regeneration within bone defects enables precise evaluation of the achieved changes, therefore allows determination of orthodontic forces positively influencing periodontium in vivo

Authors: Sendyka B. , Mitianiec W. , Noga M.
Published: June 2015

The paper presents the study of combustion process of a homogenous lean propane-air mixture in the cylindrical combustion chamber ignited by a hot gas jet from the pre-ignition chamber. A rich propane-air mixture in the pre-chamber is ignited by the spark plug and the exhaust gasses flow from the chamber trough the holes in the wall. The mathematical model of gas exchange and energy balance in chambers with a laminar finite-rate model taking into account the two-step Arrhenius chemical kinetics is presented. The work presents results of thermodynamic parameters of the charge obtained in CFD simulations in Fluent and Kiva3v for three configurations: with one hole in the wall of the ignition chamber, with three holes and without an ignition chamber. Modelling and simulation have shown faster burning of the mixture for jet ignition with three holes of the pre-chamber. The results of simulations were verified by experimental studies in the combustion chamber of the same geometry by the Schlieren method. The work presents flame front propagation, pressure traces and pressure increment speed for two mixtures with a different equivalence fuel-air ratio. Experimental results proved the simulation observation of faster flame propagation in the main chamber with three holes

Published: June 2015

In the present scenario internet usage and the online banking sectors are experiencing spectacular growth. The Internet is the fastest growing banking channel today, both in the fields of corporate and retail banking. Banks prefer their customers to use the online banking facility as it reduces their cost, primarily through labour costs. The online banking system addresses several emerging trends: customers’ demand for anytime, anywhere service, product time-to-market imperatives and increasingly complex back-office integration challenges. Online fraud has become major source of revenue for criminals all over the globe. The challenges that oppose online banking are the concerns of security and privacy of information. This has made detecting and preventing these activities a top priority for every major bank. The use of single-factor authentication, such as a user name and the password, has been inadequate for guarding against account fraud and identity theft, in sensitive online banking systems. In this paper we are going to analyze the QKD multifactor authentication in online banking systems

We report methodology of three-dimensional laser beam shaping. The analytical and numerical analysis is presented. A strategy for designing optical system involves the controlled application of aberrations which is realized by specific aspheric lens shaping. The goal is to obtain the desired optical power density distribution in space, which is optimal for selected application. The proposed method is discussed with regard to the design of optical transmitter for laser shooting simulator, however the developed methodology can be used for a number of other light shaping applications
The natural gas industry: equipment, materials, and corrosion
Authors: Valdez Benjamin , Schorr Michael , Bastidas Jose M.
Published: June 2015

Corrosion is a crucial worldwide problem that strongly affects the oil and gas industry. Natural gas (NG) is a source of energy used in industrial, residential, commercial, and electric applications. The abundance of NG in many countries augurs a profitable situation for the vast energy industry. NG is considered friendlier to the environment and has lesser greenhouse gas emissions compared with other fossil fuels. In the last years, shale gas is increasingly exploited in the USA and in Europe, using a hydraulic fracturing (fracking) technique for releasing gas from the bedrock by injection of saline water, acidic chemicals, and sand to the wells. Various critical sectors of the NG industry infrastructure suffer from several types of corrosion: steel casings of production wells and their drilling equipment, gas-conveying pipelines including pumps and valves, plants for regasification of liquefied NG, and municipal networks of NG distribution to the consumers. Practical technologies that minimize or prevent corrosion include selection of corrosion-resistant engineering materials, cathodic protection, use of corrosion inhibitors, and application of external and internal paints, coatings, and linings. Typical cases of corrosion management in the NG industry are presented based on the authors’ experience and knowledge.

Published: June 2015

Objective: To study the clinical outcome of fetal ovarian cysts managed with in utero aspiration.

Methods: All cases of fetal ovarian cysts diagnosed from 2002 to 2013 were reviewed. In utero aspiration was performed for patients with simple cysts larger than 4 cm before term gestation.

Results: There were 21 cases of fetal ovarian cysts. Four patients (19%) were diagnosed with complex cysts at the time of referral. Among the 17 cases of simple cysts, in utero aspiration was performed in seven patients. There were no complications after the therapy and none of them developed complex cysts. An ovarian cyst was confirmed by cyst fluid that contained high levels of estradiol, progesterone and testosterone. For two patients with simple cysts who met the indications for in utero aspiration but did not receive therapy, one developed a complex cyst. Among the eight patients with simple cysts who did not fulfill the indications for aspiration, seven of them had cysts that regressed spontaneously, and one developed complex cysts during pregnancy.

Conclusion: Torsion of fetal ovarian cysts was common with expectant management. Management of fetal ovarian cysts larger than 4 cm using in utero aspiration may avoid torsion, which could otherwise lead to ovarian loss.
Choosing among the Shades of Nuance: The Discourse of Proportionality in International Law
Authors: Vaypan Grigory
Published: June 2015

Proportionality has been largely misunderstood both by its proponents and by its critics. On the one hand, it has been wrongly regarded as a more transparent and at the same time a more controllable alternative to other types of legal discourses. On the other hand, it has been incorrectly viewed as a realm of unlimited subjectivity and pure politics. In fact, proportionality oscillates between law and politics, trying to reconcile the two yet constantly falling into one or another. The article studies the dialectical structure of proportionality and explores proportionality as an argumentative practice.
The role of Society for Adolescent Health and Medicine in training of health professionals
Authors: Ford Carol A.
Published: June 2015

The Society for Adolescent Health and Medicine (SAHM) was created by health professionals committed to identifying and better addressing the health needs of adolescents and young adults, and this work has continued for nearly 50 years. The society initially focused primarily on clinical education, but has evolved to include educational activities providing clinical, research, policy, advocacy, and professional development content. Strategies have included high-quality annual meetings designed to meet the educational needs of its multi-disciplinary membership, publishing an internationally recognized journal, and developing strategic collaborations to advocate for legitimacy of the field and reform in health profession education. Historically, SAHM has been most successful at increasing specialized training in the United States among physicians, and primarily pediatricians, likely driven by the nuances of the development of adolescent medicine in this country. Successes are often linked to strategic collaborations with other professional organizations, and have been facilitated by federally funded initiatives to improve adolescent and young adult health. Recent efforts to improve professional training are focused on the use of technology, and SAHM is also currently exploring strategies to directly reach adolescents, young adults, and their parents. As the society becomes increasingly multidisciplinary and international, members have extraordinary opportunities to learn from each other, build upon lessons learned, and collaborate. Descriptions of the history of SAHM’s training-focused efforts, selected highlights, and current priorities will be used to illustrate this long-standing commitment to the training of health professionals.
