Authors: Szymszal J. , Kuczyńska-Chałada M. , Król J. 
Published: May 2018

Abstract
As experience shows the practical, reliable assessment and optimisation of total costs of logistical processes implemented in supply chains of foundry plants is a quite complex and complicated process, because it requires to enclose all, without exception, performed actions, including them in various reference cross-sections, systematic activities and finally transforming them in a totally homogenous collection. Only solid analysis and assessment of assortment management in logistical supply systems in foundry plants of particular assortment groups allows to lower the supply costs significantly. In the article the analysis and assessment of the newest implemented optimising algorithms are presented in the process stock management of selected material groups used in a production process of a chosen foundry plant. A practical solution to solve a problem of rotary stock cost minimisation is given as well as of costs while creating a stock with the usage of economical volume and value of order.

On Uniform Topological Algebras
Authors: El Azhari M. 
Published: May 2018

Abstract
The uniform norm on a uniform normed Q-algebra is the only uniform Q-algebra norm on it. The uniform norm on a regular uniform normed Q-algebra with unit is the only uniform norm on it. Let A be a uniform topological algebra whose spectrum M(A) is equicontinuous, then A is a uniform normed algebra. Let A be a regular semisimple commutative Banach algebra, then every algebra norm on A is a Q-algebra norm on A.

Published: May 2018

Abstract
In this paper, we introduce the concept of a generalized weak contraction for set-valued mappings defined on quasi-metric spaces. We show the existence of fixed points for generalized weakly contractive set-valued mappings. Indeed, we have a generalization of Nadler’s fixed point theorem and Banach’s fixed point theorem in quasi-metric spaces and, further, investigate the convergence of iterate scheme of the form xn+1 ∈ Fxn with error estimates.

Abstract
The main object of this paper is to investigate λ-statistically ward continuity. We obtain some relations between this kind of continuity and some other kinds of continuities. It turns out that any λ-statistically ward continuous real valued function on a λ-statistically ward compact subset E ⊂ R is uniformly continuous.

Authors: Bodaghi Abasalt , Amini Massoud , Jabbari Ali 
Published: May 2018

Abstract
We employ the fact that L1(G) is n-weakly amenable for each n ≥ 1 to show that for an inverse semigroup S with the set of idempotents E, ℓ1(S) is n- weakly module amenable as an ℓ1(E)-module with trivial left action. We study module amenability and weak module amenability of the module projective tensor products of Banach algebras.

Magnetic Repeat Station Network on the Baltic Sea — Why So Needed?
Authors: Welker Elżbieta , Reda Jan , Pałka Andrzej 
Published: May 2018

AbstractThe development of navigation systems requires more and more accurate base data. Currently, attention is paid to utilization of geophysical fields — gravitational and magnetic ones — for navigation purposes. The Earth’s magnetic field distribution — both onshore and offshore — is complicated and variable in time. Hence, it is essential to precisely know the secular variations in the area of interest. In the case of Baltic Sea, this involves establishing (re-establishing) of a marine network of secular points (repeat stations) and regular magnetic measurements of the three independent components of the Earth’s magnetic field. Such measurements require equipment that ensures not only high stability, but also information about sensors’ orientation in relation to geographic north and to the level. This article presents a new project of the Baltic network of repeat stations and gives a solution for the instruments usable for quasi-absolute magnetic measurements.

Authors: Jarząbek Dorota , Juszkiewicz Wiesław 
Published: May 2018

Abstract
The ability to use computer simulation to predict the behavior of oil spills at sea enables better use of available personnel and resources to combat such spills. The use of oil collecting equipment properly selected to suit the conditions is essential for the operation to be effective. Therefore, an attempt is made to verify the influence of weather conditions on the efficiency of oil recovery. Three types of spilled crude oil were simulated. A relevant experiment was conducted on a PISCES II oil spill simulator.
Modeling the dynamic operation of a small fin plate heat exchanger – parametric analysis
Authors: Motyliński Konrad , Kupecki Jakub 
Published: May 2018

Abstract
Given its high efficiency, low emissions and multiple fuelling options, the solid oxide fuel cells (SOFC) offer a promising alternative for stationary power generators, especially while engaged in micro-combined heat and power (μ-CHP) units. Despite the fact that the fuel cells are a key component in such power systems, other auxiliaries of the system can play a critical role and therefore require a significant attention. Since SOFC uses a ceramic material as an electrolyte, the high operating temperature (typically of the order of 700–900 °C) is required to achieve sufficient performance. For that reason both the fuel and the oxidant have to be preheated before entering the SOFC stack. Hot gases exiting the fuel cell stack transport substantial amount of energy which has to be partly recovered for preheating streams entering the stack and for heating purposes. Effective thermal integration of the μ-CHP can be achieved only when proper technical measures are used. The ability of efficiently preheating the streams of oxidant and fuel relies on heat exchangers which are present in all possible configurations of power system with solid oxide fuel cells. In this work a compact, fin plate heat exchanger operating in the high temperature regime was under consideration. Dynamic model was proposed for investigation of its performance under the transitional states of the fuel cell system. Heat exchanger was simulated using commercial modeling software. The model includes key geometrical and functional parameters. The working conditions of the power unit with SOFC vary due to the several factors, such as load changes, heating and cooling procedures of the stack and others. These issues affect parameters of the incoming streams to the heat exchanger. The mathematical model of the heat exchanger is based on a set of equations which are simultaneously solved in the iterative process. It enables to define conditions in the outlets of both the hot and the cold sides. Additionally, model can be used for simulating the stand-alone heat exchanger or for investigations of a semiadiabatic unit located in the hotbox of the μ-CHP unit.
Identification Of Marginal Land Suitable For Biofuel Production In Serbia
Authors: Radojević Uroš , Ninković Miloš , Milovanović Jelena 
Published: May 2018

Abstract
The use of biomass as a potential energy source has both advantages and disadvantages. Biomass is a potential source of fuel energy that provides economic and environmental benefits such as less expensive and less energy intensive production, carbon sequestration and soil preservation. However, the main concern associated with biofuels is that land needed for food will be used for biofuel crops. One potential solution is the use of marginal lands which are not suited for food production. Marginal lands generally refer to the areas not only with low production, but also with limitations that make them unsuitable for agricultural practices and ecosystem functions. This can be due to various forms of land degradation such as pollution, surface exploitation of mineral resources, erosion, overexploitation and others. We used remotely sensed data, environmental data and field survey data to identify possible marginal lands in Serbia. All gathered data was transferred to GIS in order to create maps and database of potential marginal lands which could be used for biomass production.
Development of Incomes and Expenditures in Slovak Households
Authors: Lazíková Zuzana 
Published: May 2018

Abstract
The household income is one of the basic indicators of the human living standard in the countries or their regions. The indicator of income is very closely connected to the indicator of expenditures, which completes the view of the living standard of households. During the last two decades, there were some important events that have influenced the development of household incomes and expenditures in Slovakia, such as accession of the Slovak Republic into the EU, adoption of the common currency euro or economic crisis as well. In the last years, the net incomes as well as the net expenditures of the Slovak households have increased. According to the results, this trend will continue; however, the net expenditures will increase faster than the net incomes of households. Therefore, we can expect that the savings rate will decrease. On the other hand, the differences of net household income and expenditures among the regions of Slovakia were not eliminated. There is still a high difference of the net household income mainly between the Bratislava region and the Prešov region.

Published: May 2018

Abstract
Animal experiments are used on a large scale worldwide in order to develop or to refine new medicines, medicinal products or surgical procedures. It is morally wrong to cause animals to suffer, this is why animal experimentation causes serious moral problems.
We must realize that we have moral and legal obligations when dealing with animals in our care, and this should become our high priority before any experiment. We have to take responsibility for the life of the animals and we have to act honorably regarding this issue because we have been given a trust by society in general which is not to be taken lightly.
There is an ongoing societal debate about ethical issues of animal use in science. This paper is addressed to current and future researchers and is an appeal for them to (re)consider their personal views concerning the issue under scrutiny and their responsibility in ensuring that results would make the sacrifice worthwhile.

Abstract
Dupuytren’s contracture is a fibroproliferative disease whose etiology and pathophysiology are unclear and controversial. It is a connective tissue disorder, which takes part in the palmar’s fibromatosis category and has common characteristics with the healing process. Dupuytren’s disease is characterized by the flexion contracture of the hand due to palmar and digital aponevrosis. It generally affects the 4th digital radius, followed by the 5th one. Without surgery, it leads to functional impotence of those digital rays and/or hand. It is associated with other diseases and situational conditions like Peyronie’s disease, the Lederhose disease (plantar fibromatosis), Garrod’s digital knuckle-pads, diabetes, epilepsy, alcoholism, micro traumatisms, stenosing tenosynovitis and not the least with carpal tunnel syndrome. The carpal tunnel syndrome is a peripheral neuropathy with the incarceration of the median nerve at the ARC level, expressed clinically by sensory and motor disturbances in the distribution territory of the median nerve, which cause functional limitations of daily activities of the patient. After the failure of the nonsurgical treatment or the appearance of the motor deficit, is established the open or endoscopic surgical treatment with the release of the median nerve. Postoperative recovery in both diseases is crucial to the functionality of the affected upper limb and to the quality of the patient’s life. The patient, a 61 years old man, admitted to the clinic for the functional impotence of the right hand, for the permanent flexion contracture of the metacarpophalangeal joint (MCP) and proximal interphalangeal joint (PIP) of the 4th finger with extension deficit, for the damage of the thumb pulp clamp of the 4th finger, for nocturnal paresthesia of fingers I-III and pain that radiates into the fingertips. After clinical, paraclinical, imagistic and electrical investigations, surgery is practiced partial aponevrectomy, carpal ligament section, external neurolysis of the median nerve, flexor tendon tenolisys. The particularity of this case is the coexistence of two pathologies: Dupuytren’s disease and carpal tunnel syndrome, the decision to solve in the same operator time and the problem of immobilization. Reportation of this case supports previous reports in literature, such as Dupuytren’s disease and carpal tunnel syndrome are observed at the same patient, at the same time or one after another.

Abstract
In order to fulfill their function, orthodontic devices must be cemented on teeth using orthodontic rings. The retention of the orthodontic ring is influenced mainly by the type of dental-ring adhesion. This study was initiated to determine possible microleakage events while using zinc phosphate cement Adhesor (Spofa Dental), conventional glass ionomer Ketac Cem (3M ESPE) and Fuji Ortho (GC) and a compomer Transbond Plus (3M Unitek). The results of the study are consistent with those reported in the literature reference, the compomer is the preferred adhesive material for cementing the orthodontic rings, compared to conventional glass ionomer cements and zinc-phosphate cement.
Autoimmune Thyroiditis In A Population With Rheumatoid Arthritis
Authors: Claudia Mihailov , Irina Tica 
Published: May 2018

Abstract
Introduction: Autoimmune thyroiditis (AIT) associates a multitude of osteoarticular and muscular complaints but, in the same time, the association between AIT and rheumatoid arthritis (RA) remains a matter of controversy.
Material, patients and method: We performed a retrospective cross-sectional study over 69 patients with RA admitted successively in the the IInd Medical Clinic of Railway Hospital between 01 Jan 2015 and 01 Aug.2015, subdivided into two groups: with and without AIT. A number of parameters were studied in each group: age, environment, parity and number of gestations, smoker status, education level, medium duration of disease, presence of rheumatoid factor (RF), of anti-cyclic citrullinated protein antibodies (ACPA), erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels, treatment for RA, VAS score, DAS 28 score.
Conclusions: The percentage of patients with RA and AIT is 17.391%, higher than in general population, and so we consider that screening for AIT in patients with RA should be done. Patients with RA and AIT have a younger age of RA onset, belong to the urban environment and have a higher level of education than the ones with RA but without AIT. No correlation between the occurrence of AIT and the presence of ACPA was found.

Abstract
Objectives: Establishing the frequency of pleurisy from the total number of admissions in the Paediatrics Department, as well as the frequency of pleurisy from the total number of respiratory ailments that required hospitalization; evaluating age group distribution and determining the influence of environmental factors; describing clinical manifestations, laboratory, radiologic, and bacteriological investigations in patients with pleurisy; quantifying clinical manifestations and investigations so as to establish an appropriate therapeutic approach; identifying clinical aspects that indicate a favourable/unfavourable evolution; analyzing the evolution of cases after treatment as revealed by radiologic imaging.
Method: Retrospective study on 47 patients diagnosed with pleurisy and admitted in the Paediatrics Department of Constanta Clinical Emergency Hospital, over a span of 3 years (2011-2013), based on data collected from observation sheets.
Results: A downward trend in what regards the frequency of pleurisy can be observed from 2011 to 2013. Rural provenience and other environmental factors continue to play an important role. Clinical manifestations tend to be more significant for younger patients and they are directly related to the specific pathogen identified during laboratory investigations.
Conclusion: Following an early diagnosis and a subsequent adequate treatment, evolution tends to be favourable in most cases, although certain post-hospitalization measures still need to be implemented in order to ensure full recovery and restitution ad integrum.
An Assessment of Soybean (Glycine max, L. Merrill) Grain Yield in Different Environments Using AMMI and GGE Biplot Models in Humidorest Fringes of Southeast Nigeria
Authors: Edugbo Richmond Emuohwo , Nwofia Godson Emeka , Fayeun Lawrence Stephen 
Published: May 2018

Abstract
The yield of four soybean (Glycine max, L. Merrill) genotypes under six planting dates in two years was assessed using the Additive Main Effect and Multiplicative Interaction (AMMI) and Genotype and Genotype-by-Environment biplot models. The results of combined analysis of variance for grain yield of the four genotypes of soybean grown in 12 environments showed that soybean grain yield was significantly (P < 0.01) affected by environments (E), genotypes (G) and genotype by environment interactions (GE). Genotypes and environments accounted for about 6.56% and 47.66% of the variation, respectively, while the GE explained 14.47% of the variation, which is more than double of the genotypic effects of the total variation. AMMI biplot indicated genotype TGx1485-1D and the early July 2012 environment were above average for grain yield and had positive specific interactions with each other. However, TGx1485-1D had negative interactions with the other environments while genotypesTGx14482E, TGx1987-10F and TGx1835-10E had positive interactions with all the environments except E5. In the differential yield ranking of genotypes across the twelve environments TGx1485-1D had the highest yield in seven out of the twelve environments. TGx1835-10E was the highest yielding genotype in three environments, while TGx1448-2E gave the greatest yield in two environments. Although TGx1485-1D exhibited high GEI, in the GGE biplot it was ranked as the most desirable genotype. GGE biplot identified early July 2012(E5) as the best environment. The result showed that application of AMMI and GGE biplots facilitates visual comparison and identified superior genotypes for each target set of environments.
