Applicability of book value to estimate property of Polish forest management units
Authors: Adamowicz Krzysztof , Gwiazdowicz Magdalena , Szczypa Piotr 
Published: October 2017

AbstractAt present, various solutions are proposed for the appraisal of forest land and stands. Recently an important problem concerning business information is connected with the valuation of assets of individual forest districts. In practice, numerous methods are used to estimate the property of enterprises. However, there are no universal methods to estimate the value of an enterprise. One of these practically applicable methods is the book value method (BVM). In view of the above, it was decided to analyse the applicability of this method to valuate the property of forest districts. Based on the conducted case study and the discussion of results, it was found that the original BV method may not be used to appraise the property of forest districts. The primary justification for rejection of this method in the valuation of forest district property results was from the lack of financial balance information on the value of forest land and stands. As a result, the value of a forest district calculated using the BVM is underestimated. A lesser but significant effect on the estimated value of forest districts is also observed for cash flows related with the Forest Fund. In the case of net contributors, the estimated value of forest districts is overestimated and that of net beneficiaries is underestimated.

Abstract
The aim of the project was to check the influence of ammonium phosphite preparation − Actifos on the physiology of leaves and a possible reduction of infection by the fungus a year after the application of fertilizer. Three observation plots were selected in Karczma Borowa, Krotoszyn and Piaski Forest Districts (FD). In each of these observation plots, trees were chosen randomly. In Karczma Borowa FD, the trees were treated by watering them with a 3% solution of Actifos. In Krotoszyn FD, the leaves of trees were sprayed twice (in July and September) from the plane using a 50% solution of Actifos; and in Piaski FD, only the trunks of tress were sprayed twice the same way, but in July 2012 and September 2013. In October 2013, from each tested tree, ten leaves were selected randomly from the upper, well-lit parts of their crowns. The assessment of leaf surface damaged by mycelium and chlorophyll a fluorescence was performed. After the application of the phosphite, no negative physiological consequences for the treated trees were noticed − neither concerning the average leaf area nor the fluorescence of chlorophyll. The manner of phosphite application (leaves, trunks or roots) did not cause any negative consequences for the vitality/health of the treated trees as compared to the control trees. A certain tendency in the reduction of oak mildew on the treated leaves with phosphite was observed, however these observations should be continued in the next years.

Published: October 2017

Abstract
This paper summarizes information about recently worked bentonite deposits in Slovakia and presents the results of studies on bentonite from the Central Slovakia Volcanic Field (CSVF). The authors compared the mineralogy of commercial bentonites exploited in the Stara Kremnička (Jelšový potok), Kopernica, and Hliník nad Hronom deposits. X-ray diffraction (XRD), chemical analyses and microscopy showed that the main component is montmorillonite (37-88%), followed by opal C/CT (5-25%), clinoptilolite (up to 15%), feldspars (3-12%), quartz (up to 8%), biotite (2-5%), and kaolinite (up to 2%). The microscopic imaging provided information valuable for the technological assessment of bentonites, particularly the evaluation of mineralogy determined by XRD. The low variability of the mineral composition of commercial bentonites exploited in the western CSVF, together with the significant reserves and localization of deposits close to the Polish-Slovak state border prove that this raw material deserves more attention from Polish industry.
Efficiency of Pb(II) and Mo(VI) Removal by Kaolinite Impregnated with Zero-Valent Iron Particles

Published: October 2017

Abstract
In this work, kaolinite modified with zero-valent iron was synthesized and used as a sorbent for Pb(II) and Mo(VI) removal from aqueous solutions. The obtained material was characterized by X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy. The methods revealed successful modification by the Fe0particles precipitation on the surface of well-ordered kaolinite. The sorption experiment results showed a significant increase of sorption capacity in relation to the raw kaolinite. The kaolinite with 25% content of Fe0was found to be the best material for Pb(II) and Mo(VI) removal, resulting in approximately 500 mmol·kg-1and 350 mmol·kg-1sorption, respectively. The possible mechanisms responsible for metals’ removal were identified as reduction by Fe0‘core’ and adsorption on the iron hydroxides ‘shell’. The study indicated that the obtained material is capable of efficient Pb(II) and Mo(VI) removal and may be an interesting alternative to other methods used for heavy metals’ removal.

Published: October 2017

Abstract
The study compared coal fly and bottom ashes for their ability to inactivate metals and lead to soil remediation. Soil was artificially contaminated with Cu, Zn, Pb and Cd at five degrees. Next, both ashes were added at five rates: 0, 0.5, 1.0, 1.5 and 2.0% and all treatments incubated. Data showed that for moderately contaminated soils, ash rates of 0.5 - 1.0% were efficient from 40 to 70% for Zn and Cd, and raised markedly to between 70 and 93% for Cu and Pb. For extremely contaminated soils, the rates of ashes at 1.0, 1.5 and 2% were much more efficient (60 - 80%). The use of fly and bottom ashes for metal inactivation and soil remediation should give greater consideration to the effect of pH and the type of heavy metals than the content of SiO2and Al2O3. Fly ash displayed superior inactivation and remediation effects to the bottom ash.
Determining the Minimum Sum of Production Order Delays in a Two-Machine System
Authors: Jardzioch Andrzej , Dylewski Robert 
Published: October 2017

AbstractOne of the main tasks in the planning of production processes is to satisfy the needs of the customers in terms of quantity, quality and time. The issue of the timely execution of production orders is becoming increasingly important. Based on the conducted studies it can be concluded that the size of the delay depends on the adopted scheduling of orders. This paper focuses on the problem of implementing a scheduling of production orders that will allow to avoid delays, and in the event such a scheduling is not possible, for minimizing the sum of delays of all the orders. A new algorithm has been proposed that allows to determine of the optimal sequence of production orders with the minimum sum of delays. The considerations have been limited to the issue of a two-machine system in which the orders are carried out in a flow.
The Impact of the Availability of Resources, the Allocation of Buffers and Number of Workers on the Effectiveness of an Assembly Manufacturing System
Authors: Kłos Sławomir , Trebuna Peter 
Published: October 2017

AbstractThis paper proposes the application of computer simulation methods in order to analyse the availability of resources, buffers and the impact of the allocation of workers on the throughput andwork-in-progressof a manufacturing system. The simulation model of the production system is based on an existing example of a manufacturing company in the automotive industry. The manufacturing system includes both machining and assembly operations. Simulation experiments were conductedvis-à-visthe availability of the different manufacturing resources, the various allocations of buffer capacities and the number of employees. The production system consists of three manufacturing cells –each cell including two CNC machines– and two assembly stations. The parts produced by the manufacturing cells are stored in buffers and transferred to the assembly stations. Workers are allocated to the manufacturing cells and assembly stations, but the number of workers may be less than number of workplaces and are thus termed ‘multi-workstations’. Using computer simulation methods, the impact of the availability of resources, the number of employees and of the allocation of buffer capacity on the throughput andwork-in-progressof the manufacturing system is analysed. The results of the research are used to improve the effectiveness of manufacturing systems using a decision support system and the proper control of resources. Literature analysis shows that the study of the impact of buffer capacities, availability of resources and the number of employees on assembly manufacturing system performance have not been carried out so far.
LCA as a Tool for Assessing Product and Process Oriented Eco-Innovations Undertaken by Enterprises
Authors: Rybaczewska-Błażejowska Magdalena , Sulerz Aleksandra 
Published: October 2017

AbstractThis paper examines the application of life cycle assessment (LCA) as an approach to foster the product and process oriented eco- innovation of enterprises, using the fruit and vegetable processing plant as an example. LCA, which is traditionally used to assess the impacts of a single product system on the environment, was applied in the enterprise context. This was made possible by forming an indicator describing the environmental profile of an enterprise, which is calculated by the sum of the multiplication of the environmental impact assessment (LCIA) results for individual unit processes within a particular impact category and their weights reflecting the structure of production in an enterprise. In order to distinguish and indicate the direction in which an enterprise should undertake its eco-innovative actions (implementing eco-innovations within the product or production process) the LCIA results are presented individually for products and production processes. The research was conducted in full compliance with the LCA methodology. LCA proved that the analysed enterprise has the largest negative impacts on the environment in the following impact categories: marine eco-toxicity, freshwater eco-toxicity, freshwater eutrophication, human toxicity and natural land transformation. They result primarily from the consumption of thermal and electric energy in the production processes. Therefore, to improve energy efficiency, the enterprise should take eco-innovative actions in the processes applied.
Fibroblast Growth Factor-23: A Novel Biomarker for Cardiovascular Disease in Chronic Kidney Disease Patients
Authors: Papagianni Aikaterini 
Published: October 2017

Abstract
Fibroblast Growth Factor (FGF)-23 increase is considered one of the earliest biochemical abnormalities in chronic kidney disease-mineral bone disorder (CKD–MBD). Furthermore, accumulating data have provided evidence of a link between increased FGF-23 levels and cardiovascular morbidity and mortality in CKD patients as well as in several other populations including cardiology patients and general population. The cellular and molecular mechanisms underlying the deleterious effect of FGF-23 on the cardiovascular system are not yet completely defined and are the focus of intense research. However, animal and human studies have demonstrated important actions of FGF-23 in the heart and vessels through which could promote the development of cardiovascular complications in uremia. Moreover, significant interactions have been reported between FGF-23 and other well recognized cardiovascular risk factors such as renin-angiotensin system and inflammation which could account, at least in part, for the observed associations between FGF-23 and adverse clinical outcomes. Further studies are needed to clarify the mechanisms responsible for the pleiotropic actions of FGF-23 and moreover to identify whether it is a modifiable risk factor and a potential target of therapeutic interventions which could probably help to reduce the unacceptably high cardiovascular morbidity and mortality of CKD patients.

Published: October 2017

Abstract
The increased use of antibiotics for acute tonsillitis is a public health problem. 80% of the antibiotic prescriptions for acute tonsillitis are done in the Primary Care practice (PCP). The inappropriate use of the antibiotic causes bacterial resistance and treatment failure. Only patients with acute tonsillitis caused by Group A beta-hemolytic streptococcus (GAS) have benefit of the antibiotic treatment, which is a predict cause in 5-20%. In order to assess the antibiotic prescribing for acute tonsillitis by the doctors in the PCP in Macedonia we use the data from the national project about antibiotic prescribing for acute respiratory tract infections which was conducted in November 2014 during a period of 4 weeks as part of the E-quality program sponsored by the IPCRG. 86 general practitioners from Macedonia have participated. The group of 1768 patients, from 4 months to 88 years of age, with diagnosis of acute tonsillitis was analyzed. The antibiotic prescriptions according to the Centor score criteria were compared to the Cochran’s guidelines which are translated and recommended as national guidelines. 88.8% of the patients with acute tonsillitis were treated with antibiotics, of which 52.9% with Centor score 0 to 2 were treated inappropriate. The diagnosis is mostly made based on the clinical picture and the symptoms. Only (23.6%) of the patients were treated with antibiotics (Penicillin V and cephalexin) according to the guidelines.
We concluded that there is a low adherence to the national guidelines. The clinical assessment is not accurate in determining the etiology. Also, there is a high nonadherence in prescribing the first choice of antibiotics. We emphasize the need to change the general practitioners’ prescription behavior according to the guidelines.
Dimensional Stability and Accuracy of Silicone – Based Impression Materials Using Different Impression Techniques – A Literature Review
Authors: Naumovski Borjan , Kapushevska Biljana 
Published: October 2017

Abstract
A quality-made dental impression is a prerequisite for successful fixed-prosthodontic fabrication and is directly dependent on the dimensional stability, accuracy and flexibility of the elastomeric impression materials, as well as on the appropriately used impression techniques. The purpose of this paper is to provide a literature review of relevant scientific papers which discuss the use of various silicone impression materials, different impression techniques and to evaluate their impact on the dimensional stability and accuracy of the obtained impressions. Scientific papers and studies were selected according to the materials used, the sample size, impression technique, storage time, type of measurements and use of spacer for the period between 2002 and 2016. In the reviewed literature several factors that influence the dimensional stability and accuracy of silicone impression molds, including the choice of the type of viscosity, impression material thickness, impression technique, retention of the impression material on the tray, storage time before the casting, number of castings, hydrophilicity of the material, release of byproducts, contraction after polymerization, thermal contraction and incomplete elastic recovery were presented. The literature review confirmed the lack of standardization of methodologies applied in the research and their great diversity. All findings point to the superiority of the addition silicone compared to the condensation silicone.

Abstract
The authors present a rare case of giant mediastinal cyst which arises from the thymus gland, and goes down in both pleural spaces, especially in the right chest cavity where a dominant part of the cyst was present. The cyst was full with 2.5 liters of transparent fluid, and compressed surrounding structures – heart and both lungs, especially the right one which was partially collapsed.
The patient was a 52 years old woman, without any clinical symptoms. Accidentally, on the screened chest X-ray a shading in the distal third of the right chest was detected.
The case was well documented with a CT of the chest, and an indication for surgical treatment was made. The surgery was done successfully in general anesthesia according to the small right anterior thoracotomy from which a giant part of the cyst was mobilized, which was in the right pleural cavity, but, also, the thymus with the origin of the cyst in the anterior and superior mediastinum was completely removed. In the end, a part of the cyst which was in the left pleural cavity was removed.
Combining institutional theory with resource based theory to understand processes of organizational knowing and dynamic capabilities
Authors: Takahashi Adriana Roseli Wünsch , Sander Josué Alexandre 
Published: October 2017

Purpose/ Research question. A promising way to understand the development of the dynamic capabilities and the knowing process is to build a bridge between the Institutional Theory and the Resource-Based Theory (RBT). Although being needed, this approach is missing in the extant literature. So we have a research question: It possible to construct a bridge between two dimensions basing on two theoretical bodies (Institutional Theory and RBT) using an “inverted binocular” to look at knowing process enacted in a process of organizational learning, for formation of competences and dynamic capabilities?
Design/Method/Approach. This paper analyses two different theoretical frameworks in a theoretic way and proposes an interface between those.
Findings. The exploration and explication of micro-institutional processes (organizational or individual) can be connected to the macro level (societal or field level) by combining Institutional Theory with Resource Based Theory (RBT) in a multiparadigmatic view between visions and levels (cross-level).
Theoretical implications. The bridge between these two theories would enable to strengthen the comprehension of the organizational changes in the various levels of analysis, considering their mutual dependence, and the knowing process and dynamic capabilities.
Originality/Value. One of the differentials of this paper is the attention given to knowledge as the main piece for the construction of the bridge between these theories.
Research limitations/Future research. An interface between the RBT and Institutional theory is necessary for a further development and understanding of concepts such as dynamic capabilities.
Paper type – conceptual.
Impacto de Crise sobre o Comportamento de Poupança de Famílias Americanas
Authors: Gurgel Carneiro de Oliv Otávio Do Amaral , Dos Santos Felipe Israel José , Mendes-Da-Silva Wesley 
Published: October 2017

Este estudo utiliza dados do Survey of Consumer Finances (SGF) de 2007 e 2013 para examinar a propensão à poupança das famílias americanas no período de pré e pós-crise econômica, baseando-se no modelo de dois períodos de consumo/poupança de Bowman, Minehart e Rabin (1999). Esse modelo assume existência de assimetria no comportamento de poupança dos agentes em resposta a choques positivos e negativos na renda. Os resultados obtidos via modelos logit sugerem que a crise tenha aumentado a relevância de fatores como número de filhos, idade, grau de instrução, renda e incerteza econômica; enquanto patrimônio, tolerância a risco financeiro, horizonte de investimento, saúde e possuir casa própria foram fatores que perderam relevância. As evidências sugerem que eventos da magnitude da crise de 2008 podem ocasionar mudanças no comportamento financeiro dos agentes, as quais são inteiramente explicadas pelos choques financeiros.

Published: October 2017

El libro Juan Valdez, la estrategia detrás de la marca busca explicar la táctica de valorización del café colombiano desarrollada por la Federación Nacional de Cafeteros (FNC), que tiene como principal objetivo beneficiar a los caficultores colombianos a lo largo de la cadena de valor. Para ello, el texto hace un recuento del contexto del mercado cafetero mundial, haciendo énfasis en los principales proveedores y consumidores hasta finalmente centrarse en la construcción de la marca Café de Colombia® y Juan Valdez® como estrategias para darle competitividad al grano colombiano.En el cumplimiento de este objetivo, los autores usaron información primaria y secundaria, en su mayoría compuesta por documentos y libros que discutían la evolución e historia del mercado cafetero a nivel mundial. De igual manera, también emplearon do-aumentos internos de la FNC en los que consignan las estrategias desarrolladas por la organización para el posicio-namiento de la marca Juan Valdez®. Así mismo, se destacan entrevistas realizadas a expertos en el tema.El texto fue escrito por un grupo multi-disciplinario, relacionado directamente la producción caficultora colombiana y a la FNC. Inicialmente, se destaca Mauricio Reina, economista y Magíster en Relaciones internacionales, quien se ha desempeñado como Viceministro de comercio exterior e investigador de Fedesarrollo. El segundo autor, Gabriel Silva es un economista colombiano que ocupó el cargo de director de la Federación Nacional de Cafeteros durante 7 años, incluyendo el año de escritura del libro. Parte del equipo de escritura incluye dos autores que tienen un perfil con una orientación al mercadeo, lo que permite que la segunda parte del libro tenga este énfasis: el primero de ellos es Luis Fernando Samper, quien en el momento de publicación era el director de propiedad intelectual de la FNC, y la segunda es María del Pilar Fernández, asesora en asuntos económicos de la gerencia de la marca Juan Valdez®.
