Nutrient intake and the risk of pressure sore development in older patients
Authors: Lewis B.K. 
Published: December 2016

This study explored the possibility of a link between diet prior to admission to hospital and the development of pressure sores in older patients. The intention was to use this information to develop a nutrient prediction score and nutrient risk indicator. Thirty patients over the age of 75, admitted with either a fractured neck of femur or for hip replacement surgery, formed the study population. A Waterlow assessment was completed on admission and each patient answered a specially developed food frequency questionnaire. Patients in both diagnostic groups had Waterlow scores which put them into the high-risk category. A total of 20 pressure sores developed in the two groups of patients during their stay in hospital. Patients admitted for hip replacement had higher nutrient intake values than patients with fractured neck of femur and they also had a higher occurrence of pressure sores. Overall diet for all patients appeared to be adequate; however, the diet of patients with fractured neck of femur was significantly lower in both iron and vitamin C than that of patients having hip replacement surgery. The nutritional assessment tool was not as sensitive as expected and further development and validation are needed. While no firm conclusions can be drawn from this small study, the results do emphasise the importance of adequate diet in elderly patients prior to admission, especially for planned admissions for hip replacement.
A comparison of dressings in the management of surgical abdominal wounds
Authors: Cannavo M. , Fairbrother G. , Owen D. , Ingle J. , Lumley T. 
Published: December 2016

This prospective randomised trial compared the performance of three dressing protocols in the management of 36 dehisced surgical abdominal wounds: a standard alginate; a gauze moistened with sodium hypochlorite (0.05%); and a combine dressing pad. Outcomes assessed were: healing time (cm2 per day and cm3 per day), patient comfort (pain and satisfaction) and cost. There were no statistically significant differences in healing rates between the three groups but there was a trend for the combine dressing pad protocol to produce a greater reduction in wound area. The combine dressing pad protocol performed well when compared with the calcium alginate in terms of healing time, patient comfort and cost. Maximum pain was significantly greater (p=0.011) and satisfaction significantly lower among patients who received the sodium hypochlorite protocol. Costs during the in-patient phase were also substantially higher for the sodium hypochlorite protocol. Trial results support the view that sodium hypochlorite dressing protocols for surgical wounds should be abandoned.

Authors: Thomas S. , Fisher B. , Fram P.J. , Waring M.J. 
Published: December 2016

This study uses an objective test system that compares the ability of different dressings to prevent the passage of a volatile amine when applied to a wound model under simulated ‘in-use’ conditions. Five dressings containing activated charcoal were tested by this method, and a low-adherent absorbent dressing was used as a control. Results demonstrate clear differences in the ability of the products to contain the test solution and prevent the loss of the volatile diethylamine into the surrounding air. Products which combine a physical absorbent with a charcoal component show enhanced performance.
El desempeño en el nivel doctoral de educación en cifras: Ausencia de información y sugerencias para su producción
Authors: Wainerman Catalina , Matovich Iván 
Published: December 2016

Desde mediados de los 90 en la Argentina y en América Latina, se ha producido un crecimiento abrupto del nivel posgrado. Sin embargo, las tasas de graduación doctoral (y de posgrado en general) están lejos de ser satisfactorias. Desde el sentido común, “se sabe” que la graduación de los posgrados es baja, y que esto es más así en Ciencias Sociales y Humanidades (que más adelante denominaremos “Ciencias Blandas”) que en las Exactas y Naturales (que más adelante denominaremos “Ciencias Duras”), aunque no existe información completa, válida y confiable. Para enfrentar este vacío llevamos a cabo una investigación con dos objetivos: medir el desempeño (eficiencia o productividad) de 18 programas doctorales en Ciencias Exactas y Naturales y en Ciencias Sociales y Humanidades de unidades académicas con sede en Buenos Aires y el Área Metropolitana; y diseñar un procedimiento para producir información válida y confiable sobre el desempeño. Éste se definió en términos de dos dimensiones: tasas de graduación (en tiempo reglamentario y tiempo extra reglamentario) y tiempo hasta la graduación promedio por cohorte. Para ello registramos la trayectoria académica de los individuos de cada cohorte desde su inscripción hasta su graduación o deserción. Analizamos la información por cada programa y para seis cohortes agrupadas (2001-2006), también por cada programa. Nuestros resultados constataron con datos confiables y válidos que el desempeño en las Ciencias Exactas y Naturales es mejor que en las Ciencias Sociales y Humanidades; y además, diseñamos una matriz de registro de estadísticas de posgrado y una serie de recomendaciones para que los programas doctorales y de posgrado en general puedan recoger sus propias estadísticas.

Published: December 2016

Abstract
The effect of temperature on the growth dynamics of Lactobacillus plantarum in the model environment of UHT milk was investigated. Based on the experiments between temperatures ranged from 8 to 40 °C, growth dynamics of the studied isolate was positively determined by the cultivation temperature that led to increasing intensity of growth in the exponential phase (except for temperatures 38 and 40 °C). Final counts in stationary phase have reached concentrations about 107 CFU · ml−1 from initial 103 CFU · ml−1, except for marginal 8 and 40 °C. Experimentally, it was found, that optimal temperature was close to 37 °C, where the fastest specific growth rate in an exponential phase was recorded (μ = 0.7683 h−1, td = 54 min) and the stationary phase was reached after 24 h of incubation. During the growth and multiplication of Lb. plantarum, no significant decrease of pH values in comparison to initial ones in dependence on temperature were determined (0.00—0.24 units).
Crystal and molecular structure of (9aS,10S)-6-Oxo-6,7,8,9,9a,10-hexahydro-4H-thieno-[2,3-b]quinolizin-10-yl acetate

Published: December 2016

Abstract
The title compound, C13H15NO3S, is a chiral molecule with two stereogenic centres. Its absolute configuration was derrived from the synthesis and confirmed by structure determination. The expected stereochemistry of atoms C5 and C6 was confirmed to be S. The central N-heterocyclic rings are not planar and adopt a half-chair conformation. A calculation of least-squares planes showed that these rings are puckered in such a manner that the five atoms C1, C2, C3, C5 and N1 (second ring: N1, C6, C7, C10 and C11) are planar, while atoms C4 (C5) are displaced from these planes with the out-of-plane displacement of 0.582 (3) Å and 0,666 (2) Å in the second ring, respectively. Dihedral angle between the planes of the central N-heterocyclic rings is 40.0 (1)°. Crystal structure is stabilized by C—H···O hydrogen interactions.

Authors: Babicz Marek , Szyndler-Nędza Magdalena , Kasprzyk Anna , Kropiwiec Kinga 
Published: December 2016

Abstract
The objective of the study was to analyse periparturient behaviour and the reproductive parameters of native Puławska sows with regard to polymorphism (insertion/deletion) at the PRL locus as components in the assessment of maternal value. The analysis included 45 sows of known genotype at the PRL locus, which were managed under a conservation breeding programme in individual farms. Behaviour was assessed by using an ethogram of sow responses to the stockpersons and piglets during the rearing period. The production parameters included litter size between days 1 and 21, mortality, body weight and daily weight gains of the piglets during that period. The performed analyses and observations show an association between the polymorphism of PRL gene and the maternal parameters of Puławska sows. Del/Del homozygous sows exhibited significantly higher realised fertility, but the maternal characteristics were generally more favourable in sows of the PRL Ins/Ins genotype. These animals were more docile towards the stockpersons and piglets, and were characterised by lower crushing rates, generally lower litter mortality, and higher parameters of piglet growth and development.
A selection modelling approach to analysing missing data of liver Cirrhosis patients

Published: December 2016

Abstract
Methods for dealing with missing data in clinical trials have received increased attention from the regulators and practitioners in the pharmaceutical industry over the last few years. Consideration of missing data in a study is important as they can lead to substantial biases and have an impact on overall statistical power. This problem may be caused by patients dropping before completion of the study. The new guidelines of the International Conference on Harmonization place great emphasis on the importance of carefully choosing primary analysis methods based on clearly formulated assumptions regarding the missingness mechanism. The reason for dropout or withdrawal would be either related to the trial (e.g. adverse event, death, unpleasant study procedures, lack of improvement) or unrelated to the trial (e.g. moving away, unrelated disease). We applied selection models on liver cirrhosis patient data to analyse the treatment efficiency comparing the surgery of liver cirrhosis patients with consenting for participation HFLPC (Human Fatal Liver Progenitor Cells) infusion with surgery alone. It was found that comparison between treatment conditions when missing values are ignored potentially leads to biased conclusions.
Evaluation of spring barley breeding lines in a two-year multi-location experiment using some statistical methods
Authors: Zawieja Bogna , Bakinowska Ewa , Bichoński Andrzej 
Published: December 2016

Abstract
In breeding experiments conducted prior to tests connected with the registration of new breeding lines of crops, pre-preliminary and preliminary trials are carried out. In this study a comparison was made among some models of analysis of variance, in relation to the selection of new breeding lines of spring barley (Hordeum vulgare L.). The aim is to determine whether the choice of model of analysis of variance may influence the choice of tested breeding lines. The trait considered was the yield in two years of trials. A more comprehensive analysis of variance model was found to be superior. It was also found that the results of analyses performed using average measurements for lines significantly differ from those obtained on the basis of all measurements. It was concluded that the type of ANOVA model used may have an impact on inferences about breeding lines. Moreover, a lack of stability in the yields of tested lines was revealed, implying the necessity of several years of trials.

Authors: Szabelska-Beręsewicz Alicja , Bilska Agnieszka , Waszkowiak Katarzyna , Siatkowski Idzi 
Published: December 2016

Abstract
This paper concerns methods of choosing appropriate models for longitudinal studies. Attention is paid to three criteria: the marginal Akaike Information Criterion (mAIC), the conditional Akaike Information Criterion (cAIC), and the corrected conditional Akaike Information Criterion (ccAIC). We consider these criteria based on an example concerning the effect of storage time and addition of flaxseed (Linum usitatissimum L.) preparations (i.e. ground flaxseeds, defatted flaxseed meal and flaxseed ethanolic extract) on changes in lipid oxidation and fatty acid composition during the storage of liver pâté with partial substitution of fat with flax oil.
Analysis of the Tyre Loads of the Truck Tatra 815 in Interaction with the Ground
Authors: Valašková Veronika , Vlček Jozef 
Published: December 2016

Abstract
Interaction between moving vehicle and ground represents the actual problem. Traffic seismicity affects the environment and causes worsening of its parameters. Several approaches have been developed to solve the phenomena of the vehicle-ground interaction. This problem needs to be analysed as a complex system when particular elements interact together. The interaction results in unique magnitudes of the contact forces. This paper presents the results of the analysis of vehicle-ground interaction. Calculations have been made in software ADINA using Finite Element Method. Dynamic characteristics of the vehicle have been determined according to the lorry Tatra 815. Contact forces of the tyres have been applied as point and distributed load respectively.

Authors: Kortiš Ján , Daniel Ľuboš , Škarupa Milan , Ďuratný Maroš 
Published: December 2016

Abstract
The experimental modal analysis is often used to validate the accuracy of dynamic numerical models. It is also a good tool to obtain valuable information about current condition of the structures that could help to determine residual lifetime. The quality of modal testing results is highly dependent on the proper estimation of the natural frequencies from the frequency response function. This article presents the experimental modal test of the laboratory steel structure in which the natural frequencies and mode shapes are determined.
Analytical and Numerical Evaluation of Limit States of MSE Wall Structure

Published: December 2016

Abstract
Simplification of the design of Mechanically Stabilized Earth wall structures (MSE wall or MSEW) is now an important factor that helps us not only to save a time and costs, but also to achieve the desired results more reliably. It is quite common way in practice, that the designer of a section of motorway or railway line gives order for design to a supplier of geosynthetics materials. However, supplier company has experience and skills, but a general designer does not review the safety level of design and its efficiency, and is simply incorporating into the overall design of the construction project. Actually, large number of analytical computational methods for analysis and design of MSE walls or similar structures are known. The problem of these analytical methods is the verification of deformations and global stability of structure. The article aims to clarify two methods of calculating the internal stability of MSE wall and their comparison with FEM numerical model. Comparison of design approaches allows us to draft an effective retaining wall and tells us about the appropriateness of using a reinforcing element.
Effect of the autonomic nervous system on cancer progression depends on the type of tumor: solid are more affected then ascitic tumors
Authors: Horvathova L , Mravec B 
Published: December 2016

AbstractObjectives.A number of recently published studies have shown that the sympathetic nervous system may influence cancer progression. There are, however, some ambiguities about the role of the parasympathetic nerves in the modulation of growth of different tumor types. Moreover, tumor models used for investigation of the autonomic neurotransmission role in the processes related to the cancer growth and progression are mainly of the solid nature. The knowledge about the nervous system involvement in the modulation of the development and progression of malignant ascites is only fragmental. Therefore, the aim of the present article was to summarize the results of our experimental studies focused on the elucidation of the role of the autonomic nervous system in the modulation of tumor growth in animals. We are summarizing data from studies, in which not only different experimental approaches in order to influence the autonomic neurotransmission, but also different tumor models have been used.Methods.Three different types of tumor models, namely solid rat intra-abdominal fibrosarcoma, solid murine subcutaneous melanoma, and rat ascites hepatoma, and three types of interventions have been used in order to modulate the autonomic neurotransmission, specifically chemical sympathectomy, subdiaphragmatic vagotomy, or the electric stimulation of the vagus nerve.Results.We have proved a strong stimulatory effect of the sympathetic nerves on the development and growth in both solid tumors, rat fibrosarcoma as well as murine melanoma, and significant inhibitory impact on the survival time of tumor-bearing animals. The progression of ascites hepatoma in rats was not influenced by chemical sympathectomy. Modulation of parasympathetic signalization by vagotomy or vagal nerve stimulation does not affect fibrosarcoma and ascites hepatoma growth and survival of the tumor-bearing rats.Conclusions.Based on the obtained data, it seems that the solid types of tumors are suitable substrate for the direct action of neurotransmitters released especially from the sympathetic nerves. In contrast, it appears that the malignant ascites are not under the direct autonomic nerves control; however, an indirect action via the immune functions modulation cannot be excluded.

The research issue is an important one when considering how the taxes assessed on entities conducting activity that consists in the prospecting, exploration and extraction of shale gas is one of the factors determining the profitability of such activity in Poland.
Early closeout of derivatives in the light of corporate income tax
Authors: Karczyński Łukasz 
Published: December 2016

Abstract
Due to financial crisis many entrepreneurs suffered heavy losses on derivatives, mainly currency options and forward contracts. Tax authorities tend to disallow deduction of those losses from the taxable income. Many cases ended up in administrative courts, resulting in judicature controversies on the issue in question. This paper is the third of four in a cycle. The aim of the whole cycle will be to analyze deeply these controversies and suggest the proper interpretation of the legal provisions, determining whether the expenses on currency options and forward contracts should or should not be regarded as tax-deductible expenses. The aim of this paper is to determine if the rights from the derivatives are being exercised or waived (as the law provides) in case of their early closeout (which allows the deduction as well). The conducted analysis suggests that early derivative closeout realises in exercising the rights from the derivative (as the law provides) which allows the deduction.

Published: December 2016

Abstract
The paper presents an application of structural analysis in search of key drivers and barriers of forest management in two Slovak regions: Podpoľanie and Kysuce. A comparison with factors identified in selected European regions is also presented. First, various relevant factors affecting forest management were selected for both regions. The selections draw on the pool of primary data (structured in-person interviews) and secondary data (qualitative analysis of national and European documents). Second, factors were grouped according to the STEEP categories (Society, Technology, Economy, Ecology, and Policy). Subsequently, factors were rigorously assessed by the regional stakeholders in participatory workshops, and their answers were analysed by structural analysis with the help of Parmenides EIDOS™ software. The results show that in both Slovak regions political, economic, and ecological factors dominated over social and technological factors. The comparison with selected European regions revealed that in the Slovak and other European regions, the Policy category dominated due to having the highest number of factors and their overall impact on forest management. In contrast, the least important societal domain was Technology in both the Slovak and other European regions. However, while stakeholders across the selected European regions perceived the Society domain as significant, stakeholders in both Slovak regions perceived the Economy and Ecology domains as more significant.

Abstract
We conducted a phytosociological analysis of more than 250 relevés in the Julian Alps and compared them with similar communities elsewhere in the Alps and in the Dinaric Alps to describe the following new syntaxa of alpine swards and heathlands from the alliance Caricion firmae (class Elyno-Seslerietea): Saxifrago squarrosae-Caricetum mucronatae, Saussureo pygmaeae-Caricetum rupestris, Seslerio sphaerocephalae-Dryadetum octopetalae, Homogyno discoloris-Vaccinietum gaultherioidis, Saxifrago paniculatae-Caricetum fuliginosae and Homogyno discoloris-Loiseleurietum caricetosum firmae, the new association Achilleo clavennae-Elynetum myosuroidis from the alliance Oxytropido-Elynion and two new syntaxa from the alliance Loiseleurio-Vaccinion (class Loiseleurio-Vaccinietea): Homogyno alpinae-Vaccinietum gaultherioidis and Empetro-Vaccinietum gaultherioidis rhododendretosum hirsuti. Many species that are rare, of conservation concern or protected in Slovenia occur in the newly described communities.

Published: December 2016

Abstract
Working safely and successfully in highly automated human-machine interfaces of future aviation is not only a matter of performance, but also of personality. This study examines which personality aspects correlate with safety-critical performance in human-machine teams. The research tools HTQ (Hybrid Team Questionnaire) and HINT (Hybrid Interaction Scenario) were combined for a comprehensive exploratory study. The HTQ includes personality scales measuring broad factors of personality (Big Five) as well as more specific scales and was added with objective personality assessments to measure risk taking. The simulation tool HINT simulates relevant processes in future human-machine team interaction in aviation. In a study with 156 applicants for aviation careers, safety-critical relations of some facets of general personality as well as risk taking were found. Especially personality aspects concerning disinhibiting, spontaneous behaviour and sensation seeking show correlations with poorer performance in the HINT simulation.
