Published: January 2019

The bony fish Lophotus lacepede (Giorna, 1809) and Zu cristatus (Bonelli, 1819) are the two species rarely recorded within the Mediterranean basin, usually reported as accidentally captured in depth (mesopelagic) fishing operations. In the current work, we present the first record of L. lacepede and Z. cristatus in fishing catches from southwestern Tyrrhenian Sea. Moreover, in order to improve existent biological/ ecological knowledge, some bio-related aspects such as feeding aspect, sexual maturity and age estimate have been discussed.
A long term (1949-2010) study of catch and effort in Israeli trawl fishery, Eastern Mediterranean Sea
Authors: Golani Daniel , Edelist Dor , Lerner Amit , Sonin Oren , Motro Uzi
Published: January 2019

The trawl fishery of the Mediterranean coast of Israel was analyzed vis á vis catch and fishing effort for the years 1949-2010. The Maximum Sustainable Yield (MSY) was calculated using the Fox surplus-yield model and was found to be 1,413 ton per annum using 1,415 units of effort (fishing days X engine power divided by 1000). Only during nine years (1997-2005) did fishing effort exceed the value for which the yield is the MSY by an average of 184.9 units of effort, but the yield was similar to that of the previous years. During 10 years the catch exceeded the MSY by an average of 153±119 tons. This result was used to justify the “freezing” of the local trawl fleet at the beginning of the 1990’s.
To what extent the size fraction affects an interpretation of planktonic foraminiferal assemblages
Authors: Markulin Krešimir , Ćosović Vlasta
Published: January 2019

Study of planktonic foraminifera, sampled from two levels of a 26 cm thick core, recovered at 1,200 m water depth, sheds some lights on the composition of foraminiferal assemblages that occur in the Southern Adriatic. Altogether 15 planktonic species (including one referred as undeterminable and two species recorded for the first time in the eastern Adriatic Sea) identified from 0-2 cm and 24-26 cm sediment intervals, were grouped into two assemblages: >63 μm fraction Turborotalita quinqueloba and >125 μm fraction as Globigerina bulloides-Globigerinoides ruber. The differences in core-top and core-bottom assemblages lie in: a) change in the relative proportion of some species; and b) slight differences in diversity indices. The relative proportions of species are strongly controlled by sieve mesh size, whereas the slight increase in diversity follows the increase in sieve mesh size. The benthic foraminifera, although constituting a negligible quantitative factor, show a slight increase in abundance and diversity of species with age.
Unusual bloom of tetrasporophytes of the non-indigenous red alga Asparagopsis armata in the northern Adriatic Sea
Authors: Orlando-Bonaca Martina , Mavrič Borut , Trkov Domen , Lipej Lovrenc
Published: January 2019

The tetrasporophyte of the non-indigenous red alga Asparagopsis armata (the Falkenbergia stage) is considered to be established in Slovenian coastal waters. However, until 2016, it was found only in low coverage and in few localities with hard substrata. The paper reports a recent bloom of these tetrasporophytes in the mediolittoral belt of the Bay of Piran, where thalli of this red alga overgrew the articularted coralline alga Corallina officinalis. The sites affected by this large expansion of tetrasporophytes of A. armata should be regularly monitored in the future, in order to point out which environmental factors are responsible for such phenomenon, and to formulate proper conclusions on the status of this non-indigenous alga in the coastal area concerned.
Assessment of the effects of bisphenol-A as a disruptor on ionic regulation in Danio rerio zebrafish through a study of their chloride and prolactin cells
Authors: Barasona Maria I. , Molina Ana , Blanco Alfonso , Ayala Nahum , Moyano Rosario
Published: January 2019

Bisphenol A (BPA) is one of the chemicals produced in the largest volume in the world. It is commonly used as a component of plastics and food containers and can act as a xenoestrogen in humans. In view of the risk of exposure to it from the environment and diet, and basically as a water pollutant, the objective of our study was to assess possible effects on ionic regulation after exposure to BPA by means of a histopathological and morphometric study of the chloride and prolactin cells in zebrafish (Danio rerio) as an experimental model. Twenty-five male 16-week old zebrafish (Danio rerio) were allocated randomly into 5 study groups (n=5/group); a control group, and four groups, exposed for 2 weeks to a concentration of (1, 10, 100 and 1000 μg/L) of BPA, respectively. After 2 weeks, the animals were sacrificed and samples of their gills and pituitary gland were immediately taken for their subsequent histopathological analysis. Our results showed how, in the first study groups, lesions appeared in chloride cells, generating compensatory modifications in the prolactin cells, which were enough to maintain stability in the ionic exchange. As the exposure concentration increased, more serious histological modifications occurred. In the groups with the highest concentration (100 and 1000 μg/L), the lesions were so severe that the prolactin cells underwent some degenerative processes, which probably prevented the compensatory action at gill level.

Authors: Dobroslavić Tatjana , Mozara Renata , Glamuzina Branko , Bartulović Vlasta
Published: January 2019

The reproductive characteristics of bogue (Boops boops) in the southeastern Adriatic Sea are presented in this study. The analysis is based on 676 specimens caught by seine net from December 2011 to November 2012. Total length of females ranged from 13.3 to 29.3 cm and males from 15.1 to 26.3 cm. The overall sex ratio of females to males was 1:0.85 (χ2=4.314; P < 0.05) with a slightly higher number of females in the largest size class. Length-weight relationship for the total population indicated negative allometric growth (b=2.911). Values of the condition factor are relatively low for both sexes. Maximum values were recorded in September 1.025 for females and 1.029 for males. Gonadosomatic index and histological examination showed that the spawning season of the bogue in the Adriatic is from January to May with peak in February. Six stages of gonad development were identified: immature, undergoing maturation, ripening, ripe, spawning and spent. The monthly distribution of the different sexual maturity stages and the frequency distribution of oocyte diameter revealed that this species is a batch spawner.

Authors: Katona Géza , Lénárt Balázs , Juhász János
Published: January 2019

During travelling, more and more information must be taken into account, and travelers have to make several complex decisions. In order to support these decisions, IT solutions are unavoidable, and as the computational demand is constantly growing, the examination of state-of-the-art methodologies is necessary. In our research, a parallelized Ant Colony algorithm was investigated, and a parameter study on a real network has been made. The aim was to inspect the sensibility of the method and to demonstrate its applicability in a multi-threaded system (e.g. Cloud-based systems). Based on the research, increased effectiveness can be reached by using more threads. The novelty of the paper is the usage of the processors’ parallel computing capability for routing with the Ant Colony algorithm.
Calibrating Partial Factors – Methodology, Input Data and Case Study of Steel Structures
Authors: Nadolski Vitali , Rózsás Árpád , Sýkora Miroslav
Published: January 2019

Partial factors are commonly based on expert judgements and on calibration to previous design formats. This inevitably results in unbalanced structural reliability for different types of construction materials, loads and limit states. Probabilistic calibration makes it possible to account for plentiful requirements on structural performance, environmental conditions, production and execution quality etc. In the light of ongoing revisions of Eurocodes and the development of National Annexes, the study overviews the methodology of probabilistic calibration, provides input data for models of basic variables and illustrates the application by a case study. It appears that the partial factors recommended in the current standards provide for a lower reliability level than that indicated in EN 1990. Different values should be considered for the partial factors for imposed, wind and snow loads, appreciating the distinct nature of uncertainties in their load effects.
Enhanced Artificial Coronary Circulation System Algorithm for Truss Optimization with Multiple Natural Frequency Constraints
Authors: Kaveh Ali , Kooshkbaghi Mohsen
Published: January 2019

In this paper, an enhanced artificial coronary circulation system (EACCS) algorithm is applied to structural optimization with continuous design variables and frequency constraints. The standard algorithm, artificial coronary circulation system (ACCS), is inspired biologically as a non-gradient algorithm and mimics the growth of coronary tree of heart circulation system. Designs generated by the EACCS algorithm are compared with other popular evolutionary optimization methods, the objective function being the total weight of the structures.Truss optimization with frequency constraints has attracted substantial attention to improve the dynamic performance of structures. This kind of problems is believed to represent nonlinear and non-convex search spaces with several local optima. These problems are also suitable for examining the capabilities of the new algorithms. Here, ACCS is enhanced (EACCS) and employed for size and shape optimization of truss structures and six truss design problems are utilized for evaluating and validating of the EACCS. This algorithm uses a fitness-based weighted mean in the bifurcation phase and runner phase of the optimization process. The numerical results demonstrate successful performance, efficiency and robustness of the new method and its competitive performance to some other well-known meta-heuristics in structural optimization.

Authors: Iványi Tamás , Bíró-Szigeti Szilvia
Published: January 2019

Many cities in Hungary have an application specially developed for smartphones that try to satisfy both the needs of tourists and local residents. These "products" are based on different objectives of city marketing and destination marketing: their goal is to make shorter or longer stays more comfortable, provide faster and more personalized information, help consumers to turn their offline experiences into online experience sharing and to provide a platform for two-way communication between local and touristic consumers. In addition to the marketing literature review related to smartphones and local tourism experiences, this paper presents the results of a quantitative questionnaire focusing on the needs of Generation Z concerning application functions. Based on the quantitative results, the members of Generation Z are classified into three main groups with the k-means cluster analysis. Among the groups, there are significant differences between the functional requirements of city marketing applications, and according to the size of the groups three main application types and two main ways of software development can be distinguished. The results also show that there are four main group of functions and connected to the different clusters application functions appear together in the needs of consumers. However, the analysis and comparison of the related data together show also that there are only small differences concerning demographic and device-usage variables between the groups defined by the k-means cluster analysis, and this requires more research methods to be conducted in the future based on the results of this exploratory survey research.

Authors: Pardo Kennet , Cogley Karen , Cisneros Alejandra , De Gracia Stephanie , Tejedor De León Alexis
Published: January 2019

Este proyecto elaborado en la asignatura Ciencia de los Materiales, tuvo como objetivo fundamental aprovechar las

cáscaras de la naranja, tanto en su forma natural como en la forma activada, para utilizarlas como sustratos en la absorción de poluentes disueltos en efluentes sintéticos. Las muestras utilizadas en los ensayos de bioabsorción, pasaron por diferentes operaciones unitarias: obtención de las cáscaras, secado, molienda, tamizado y carbonización térmica. Los ensayos fueron realizados para la remoción de pigmentos y sales disueltas en un efluente artificial, simulando este ser proveniente de una industria textil. Resultados preliminares indican que, tanto los sustratos de la biomasa seca, como aquél de su forma activada, no presentan diferencias significativas, al menos desde una perspectiva visual, es decir, que ambos sustratos remueven el pigmento disuelto en el efluente tratado, con ellos. Sin embargo, en lo que a la conductividad, a la salinidad y el pH del efluente, aquél tratado con la biomasa, presentó mejores niveles de remoción que el tratado con su forma activada. Lo anterior permite concluir, aunque de manera preliminar, que la cáscara de naranja al natural y de forma pulverizada, es mejor precursor como bioabsorbente para la remoción de pigmentos y sales disueltos en efluentes sintéticos, por lo que se hace necesario realizar más experiencias para corroborar lo anteriormente expuesto.

Penanaman paradigma makanan berbasis singkong sedini mungkin pada kelompok sasaran dengan melalui demontrasi olah singkong dan (ii) Analisis responsi kelompok sasaran pasca demontrasi olah singkong dengan deversifikasi produk Metode analisis pada  action research dilakukan dengan pendekatan participatory rapid appraisal dengan banyak tahap. Sedangkan untuk menjawab responsi kelompok digunakan analisis logit model.  Hasil analisis menunjukkan bahwa (1) Penanaman paradigma makanan berbasis singkong menunjukkan bahwa singkong bisa dibuat untuk makanan yang menarik, anak-anak dipersilahkan untuk memakan. Dari sinilah kemudian ajaran/paradigma ditanamakan kepada anak-anak (mereka) makan adalah ‘apa saja’ tidak hanya nasi dan makan adalah untuk ibadah. Oleh karena itu perlu dianalisis ‘makan’ dari aspek spiritual guna mengembangkan ilmu pengetahuan yang lebih luas dan integratif.  (2)  Analisis responsi kelompok sasaran pasca demontrasi olah singkong dengan deversifikasi produk. Hasil analisis dari lima variabel tersebut mempunyai pengaruh yang negatif, yaitu  umur kelompok sasaran, jumlah anggota keluarga, pendidikan, konsumsi singkong per hari. Sedangkan pendapatan mempunyai pengaruh positif.  Dari hasil penelitian ini disarankan bahwa meskipun tidak mudah dalam melakasanakan penanaman paradigma, tetapi minimal ada yang memulai sebab paradigma sesuatu tindakan tang berupaya untuk merubah perilaku – maka dari itu perlu waktu yang cukup lama. Atas dasar itulah, maka pada penelitian ini disarankan beberapa hal (i) semua pihak diharapkan mempunyai kontribusi yang positif terhadap upaya ketahanan pangan melalui teori ‘makan tidak hanya nasi’ – utamanya pada anak sedini mungkin dan (ii) problem yang muncul dari penelitian tahun I, II dan II, yaitu kekurangan bahan baku singkong dapat diatasi dengan jalan pemanfaatan lahan kosong, lahan pekarangan, dll agar produksi singkong (exes demand) dapat teratasi, minimal terkurangi. Hal ini akan dilakukan pada skim penelitian yang lainnya

Reorientasi Pemikiran Al-Ghzali Tentang Maslahah Mursalah Dengan Pembaruan Hukum Islam
Authors: Suratmaputra Ahmad Munif
Published: January 2019

Wahyu terbagi menjadi dua istilah yakni wahyu matluw, yaitu al-Qur‟an al-Karim, dan wahyu gairu matluw, yaitu as-Sunnah dan al-Hadis. Kehadiran hukum Allah atau hukum Islam (ahkam syar‟iyyah) yang harus dijadikan pedoman dan acuan untuk mewujudkan kemaslahatan bagi umat manusia. Atas dasar ini, para pakar fiqh dan ushul fiqh telah konsensus bahwa maslahat atau kemaslahatan merupakan tujuan inti pensyari‟ atau hukum Islam : sehingga muncullah ungkapan yang sangat populer dikalangan mereka : فثم حكم الله أينما كانت الدصلحة (dimana ada maslahat, disanalah ada hukum Allah).Menyadari bahwa tidak semua masalah kehidupan ini hukumnya ditemukan didalam al-Qur‟an dan as-Sunnah/Hadis, Islam meletakkan prinsip-prinsip umum dan kaidah-kaidah dasar yang dapat dijadikan oleh ahl az-Zikri (para mujtahid) untuk mengembangkan hukum Islam dan memecahkan masalah-masalah baru melalui ijtihad. Salah satu prinsip umum dan kaidah dasar yang diletakkan oleh Islam ialah bahwa tujuan pokok tujuan pensyar‟i atau hukum Islam adalah untuk mewujudkan kemaslahatan (jalb al-masalaih). Dari prinsip inilah prinsip para imam mujtahid dan pakar ushul fiqh mengembangkan hukum Islam dan berusaha memecahkan masalah-masalah baru yang dihadapi oleh umat Islam yang belum ada penegasan hukumnya di dalam al-Qur‟an dan as-Sunnah melalui qiyas, istihsan, maslahah mursalah dan sad az-Zari‟ah.Al-Ghazali (450–505 H.) sebagai pakar ushul fiqh dari kalangan madzhab Syafi‟i, mempunyai pemikiran-pemikiran yang cukup menarik tentang maslahah mursalah. Pandangannya tentang maslahah mursalah merupakan jalan tengah antara pihak-pihak yang sama sekali tidak mempergunakan maslahah mursalah sebagai dalil hukum dan mereka yang begitu berani dalam menjadikan maslahah mursalah.

Patients with end-stage kidney disease (ESKD) have different options to replace the function of their failing kidneys. The “integrated care” model considers treatment pathways rather than individual renal replacement therapy (RRT) techniques. In such a paradigm, the optimal strategy to plan and enact transitions between the different modalities is very relevant, but so far, only limited data on transitions have been published. Perspectives of patients, care-givers, and health professionals on the process of transitioning are even less well documented. Available literature suggests that poor coordination causes significant morbidity and mortality.

This review briefly provides the background, development, and scope of the INTErnational Group Research Assessing Transition Effects in Dialysis (INTEGRATED) initiative. We summarize the literature on the transition between different RRT modalities.

Further, we present an international research plan to quantify the epidemiology and to assess the qualitative aspects of transition between different modalities.
INVESTIGATION OF THE SPEAKER IDENTIFICATION METHOD BASED ON CLUSTERED PSEUDOSTATIONARY SEGMENTS OF VOICED SOUNDS
Authors: Treigys Povilas , Lipeika Antanas
Published: January 2019

The problem of speaker identification is investigated. Basic segments ‐ pseudo stationary intervals of voiced sounds are used for identification. The identification is carried out, comparing average distances between an investigative and comparatives. The coefficients of the linear prediction model (LPC) of a vocal tract are used as features of identification. Such a problem arises in stenographic practice where it is important for speech identification to know who is speaking. Identification should be used in stenography and it has to be fast enough in order not to disturb the stenographer's job. The clustered parameter data will be investigated by providing the performance of the speaker identification method with respect to the computational time and the number of errors.
HEURISTIC ANALYSIS OF INVESTMENT STRATEGY
Authors: Vakrinienė Sigutė , Pabedinskaitė Arnoldina
Published: January 2019

The present article investigates the problem of optimal investment, when, given a limited amount of funds, a decision must be taken to which projects and what amounts of funds are to be invested. Supposing that the expected average profit depends on several possible different market conditions, a matrix .game against nature. has been selected as the initial mathematical model. With a view to develop the optimal investment strategy, a linear programming task is formulated. The sensitivity of solutions to profitability coefficients is analysed by means of formulating a dual task for this task. The present article considers the stability and dynamics of the optimum investment strategy given a varying amount of the funds allocated to investment and the profitability of specific projects.

Sustaining questioning of experts and other sources of information evaluated the consequences and magnitudes indexes. Using the multipurpose method of evaluation CORPAS (Complex Proportional Assessment) the string of priority was made.
CHOSEN ASPECTS OF DEFINING TECHNICAL WEAR OF BUILDINGS
Authors: Konarzewska Malgorzata , Konarzewski Artur
Published: January 2019

The article discusses the problem of defining borderline values of technical wear of a building and/or its components. Formulas and methods of defining wear have been highlighted, and an example has been presented, where the calculations were made according to proportionality formulas: Ross and Unger, Romstorfen and Eytelwein. While analysing results, some differences have been pointed out in the assessment of the degree of wear, depending on the time lapse and selection of a calculation formula. Selecting an inappropriate calculation procedure (depending on the focus on an element), and incorrect manner of defining technical life span of an element or a whole building leads to serious errors. The justifiability of the above statement has been proved in the summary, where a comparison of element use, according to different calculation formulas, has been presented in a graphic form.
DETERMINATION OF THE CONSTRUCTION TIME FOR BRIDGES OVER RAILWAY LINES FROM THE PUBLIC CLIENTS’ PERSPECTIVE
Authors: Löbner Bernhard
Published: January 2019

When a public client produces any construction specifications for the offerers, he must first know the estimated starting and finishing dates of the construction work. During the next step, when sending out the specifications to the offerers, he must include specific construction time. Depending upon this specific time, the contract will be negotiated. Thus, the public client is in possession of the specifications, but he is given neither a binding price nor the construction plans. Without knowing the calculations of the offerers, a public client has a limited period to determine the exact, economic construction time. Furthermore, the public client also takes all responsibility for any technological and security risks that may occur. With a special focus on the construction of bridges crossing railway lines, the author will now explain solutions to the above mentioned predicament.

MAINTENANCE STRATEGY FOR MUNICIPAL BUILDINGS FROM THE VIEWPOINT OF FACILITY MANAGEMENT
Authors: Reichelt Bernd
Published: January 2019

Maintenance of property is an important cost factor which ensures the durability of a building and its availability. The appreciation of regular maintenance measures is often missing. In the article the general tasks of the maintenance and the principles of maintenance strategies are worked out from the viewpoint of facility management. By a case study of municipal buildings the approaches of professional maintenance are shown. The solution introduced has led to a reduction of the necessary costs and also to preservation or an improvement of functionality. It has made possible for large cost safety and medium and long‐term planning of the expenses.

MODELLING OF INTERBANK PAYMENTS
Authors: Bakšys Donatas , Sakalauskas Leonidas
Published: January 2019

Non‐cash payments are intensively growing in the payment market. Therefore modern electronic systems of interbank payments are introduced to satisfy this need. The substantial renewal of the payment system was prompted for the implementation of the new banking technologies and aimed at increasing fund turnover as well as complying with the requirements applied in regard of payment systems. Such a system change is a topical theme of discussion on the simulation and analysis of systems of such kind. The article analyses the opportunities for simulating the interbank payment system and presents a model of interbank payments flow. The model is constructed on the analysis of real flow of payments in the payment system.
APPLICATION OF STATISTICAL CRITERIA TO OPTIMALITY TESTING IN STOCHASTIC PROGRAMMING
Authors: Sakalauskas Leonidas , Žilinskas Kestutis
Published: January 2019

In this paper the stochastic adaptive method has been developed to solve stochastic linear problems by a finite sequence of Monte‐Carlo sampling estimators. The method is grounded on adaptive regulation of the size of Monte‐Carlo samples and the statistical termination procedure, taking into consideration the statistical modeling error. Our approach distinguishes itself by treatment of the accuracy of the solution in a statistical manner, testing the hypothesis of optimality according to statistical criteria, and estimating confidence intervals of the objective and constraint functions. The adjustment of sample size, when it is taken inversely proportional to the square of the norm of the Monte‐Carlo estimate of the gradient, guarantees the convergence a. s. at a linear rate.

We examine four estimators for stochastic gradient: by the differentiation of the integral with respect to x, the finite difference approach, the Simulated Perturbation Stochastic Approximation approach, the Likelihood Ratio approach. The numerical study and examples in practice corroborate the theoretical conclusions and show that the procedures developed make it possible to solve stochastic problems with a sufficient agreeable accuracy by means of the acceptable amount of computations.
MODELLING OF VILNIUS PUBLIC TRANSPORT ROUTE NETWORK
Authors: Ušpalytė-Vitkūnienė Rasa
Published: January 2019

The territory of the town is divided into areas: residential, industrial and recreational. Such division of the town into areas make inhabitants increasingly dependent on the transport system.

In Lithuania and in other European countries the public transport is recognised as priority transport. In the towns of Lithuania, differently from other places, attention paid to it is insufficient, and the network of routes is being changed in a chaotic and unreasonable way.

Modelling of Vilnius public transport was carried out with the help of VISUM software. The aim of modelling is to guarantee higher quality of living of inhabitants by modelling a public transport route network in Vilnius. A three‐level public transport network was formed: main, service and feeder routes, which facilitated rational provision of Vilnius inhabitants with the public transport services.
Pushing Automated Abundance Derivations into the Cool Dwarf Regime: A Test Using Three G and Two K Stars in Praesepe∗

Published: January 2019

We present the results of an abundance analysis of three G and two K dwarfs in the Praesepe open cluster based on high-resolution, moderate signal-to-noise-ratio spectra obtained with the ARC 3.5 m Telescope at Apache Point Observatory. Using a principal component analysis and the BACCHUS automated spectral analysis code, we determined stellar parameters and abundances of up to 24 elements for each of our targets, which range in temperature from 6000 to 4600 K. The average derived iron abundance for the three G stars is 0.17 ± 0.07 dex, consistent with the 0.12 ± 0.04 dex derived by Boesgaard et al. for their sample of 11 solar-type Praesepe members, which included these G stars. To investigate the efficacy of using automated routines to derive the abundances of cooler main-sequence stars, we compared the abundances of the K dwarfs to those of the G dwarfs. Our abundances are consistent to ≤0.1 dex for 13 of the 18 elements we report for all five of the stars, providing more evidence that G and K stars in a given open cluster are chemically homogeneous. The median difference between the mean G and K stars’ abundances is 0.08 ± 0.05 dex, despite serious challenges with the noisier data for the fainter K dwarfs. Our results are encouraging for chemical tagging, as they indicate that it may be possible to use automated abundance determination techniques to identify chemically related main-sequence stars across larger temperature ranges than are usually considered in these experiments.
