Petrology of nepheline syenite pegmatites in the Oslo Rift, Norway: Zr and Ti mineral assemblages in miaskitic and agpaitic pegmatites in the Larvik Plutonic Complex
Authors: Andersen Tom , Erambert Muriel , Larsen Alf Olav , Selbekk Rune S. 
Published: August 2014

Abstract
Agpaitic nepheline syenites have complex, Na-Ca-Zr-Ti minerals as the main hosts for zirconium and titanium, rather than zircon and titanite, which are characteristic for miaskitic rocks. The transition from a miaskitic to an agpaitic crystallization regime in silica-undersaturated magma has traditionally been related to increasing peralkalinity of the magma, but halogen and water contents are also important parameters. The Larvik Plutonic Complex (LPC) in the Permian Oslo Rift, Norway consists of intrusions of hypersolvus monzonite (larvikite), nepheline monzonite (lardalite) and nepheline syenite. Pegmatites ranging in composition from miaskitic syenite with or without nepheline to mildly agpaitic nepheline syenite are the latest products of magmatic differentiation in the complex. The pegmatites can be grouped in (at least) four distinct suites from their magmatic Ti and Zr silicate mineral assemblages. Semiquantitative petrogenetic grids for pegmatites in log aNa2SiO5 - log aH2O - log aHF space can be constructed using information on the composition and distribution of minerals in the pegmatites, including the Zr-rich minerals zircon, parakeldyshite, eudialyte, låvenite, wöhlerite, rosenbuschite, hiortdahlite and catapleiite, and the Ti-dominated minerals aenigmatite, zirconolite (polymignite), astrophyllite, lorenzenite, titanite, mosandrite and rinkite. The chemographic analysis indicates that although increasing peralkalinity of the residual magma (given by the activity of the Na2Si2O5 or Nds component) is an important driving force for the miaskitic to agpaitic transition, water, fluoride (HF) and chloride (HCl) activity controls the actual mineral assemblages forming during crystallization of the residual magmas. The most distinctive mineral in the miaskitic pegmatites is zirconolite. At low fluoride activity, parakeldyshite, lorenzenite and wöhlerite are stable in mildly agpaitic systems. High fluorine (or HF) activity favours minerals such as låvenite, hiortdahlite,rosenbuschite and rinkite, and elevated water activity mosandrite and catapleiite. Astrophyllite and aenigmatite are stable over large ranges of Nds activity, at intermediate and low water activities, respectively.
The Profile and Work of Officials in Central and Regional Administration Compared: The Case of the Czech Republic
Authors: Veselý Arnošt 
Published: August 2014

Abstract
This paper examines the profiles and work tasks of officials in central and regional administration in the Czech Republic. It analyzes data from surveys among the officials of eleven ministries in 2013 (N = 1351) and fourteen regional offices in 2012 (N = 783). First, the profile of ministerial officials (MOs) is compared with that of regional-level officials (ROs). In accordance with our hypotheses, on average it is found that MOs are, when compared to ROs, older, more educated and have spent more time in civil service. Th ere is also a higher proportion of men in ministries than in regional offices. On the other hand, ministerial work seems to be affected by higher levels of fluctuation than jobs in the regional offices. Second, we compare work tasks of MOs and ROs. As expected, MOs are more involved in analytical tasks and research than ROs. In contrast, ROs are more likely to implement policies or programs, direct and monitor programs or lower-level bodies, provide advice for political bodies of the region, negotiate with elected politicians, communicate with citizens and provide methodological guidance, train or lecture. Contrary to our theoretical expectations, we found a strong positive correlation between analytical and brokering tasks (communication and negotiation). We thus reject the hypothesis that analytical tasks are at odds with negotiating and communication. Instead, it is concluded that most officials are multitaskers, and it is especially so in regional offices. It is hypothesized that this might be caused by the fact that regional offices are smaller and have a lower capacity to specialize
Parametric Method For Evaluating Optimal Ship Deadweight
Authors: Michalski Jan P. 
Published: August 2014

Abstract
The paper presents a method of choosing the optimal value of the cargo ships deadweight. The method may be useful at the stage of establishing the main owners requirements concerning the ship design parameters as well as for choosing a proper ship for a given transportation task. The deadweight is determined on the basis of a selected economic measure of the transport effectiveness of ship - the Required Freight Rate (RFR). The mathematical model of the problem is of a deterministic character and the simplifying assumptions are justified for ships operating in the liner trade. The assumptions are so selected that solution of the problem is obtained in analytical closed form. The presented method can be useful for application in the pre-investment ships designing parameters simulation or transportation task studies.

Published: August 2014

Abstract
A mathematical representation of calm-water resistance for contemporary planing hull forms based on the USCG and TUNS Series is presented. Regression analysis and artificial neural network (ANN) techniques are used to establish, respectively, Simple and Complex mathematical models. For the Simple model, resistance is the dependent variable (actually R/Δ for standard displacement of Δ = 100000 lb), while the Froude number based on volume (FnV) and slenderness ration (L/V1/3) are the independent variables. In addition to these, Complex model’s independent variables are the length beam ratio (L/B), the position of longitudinal centre of gravity (LCG/L) and the deadrise angle (β). The speed range corresponding to FnV values between 0.6 and 3.5 is analyzed. The Simple model can be used in the concept design phases, while the Complex one might be used for various numerical towing tank performance predictions during all design phases, as appropriate

Abstract
During ship sailing on rough water, relative ship motions can be observed which make the propeller emerge from the water, and decrease its thrust as a consequence. The article presents a simplified method for calculating the thrust decrease and the time of propeller emergence from water for the ship on a regular an irregular wave. The method can be used for predicting the operating speed of the ship on a given shipping lane.
A Model for Service Life Control of Selected Device Systems
Authors: Zieja Mariusz , Ważny Mariusz 
Published: August 2014

Abstract
This paper presents a way of determining distribution of limit state exceedence time by a diagnostic parameter which determines accuracy of maintaining zero state. For calculations it was assumed that the diagnostic parameter is deviation from nominal value (zero state). Change of deviation value occurs as a result of destructive processes which occur during service. For estimation of deviation increasing rate in probabilistic sense, was used a difference equation from which, after transformation, Fokker-Planck differential equation was obtained [4, 11]. A particular solution of the equation is deviation increasing rate density function which was used for determining exceedance probability of limit state. The so-determined probability was then used to determine density function of limit state exceedance time, by increasing deviation. Having at disposal the density function of limit state exceedance time one determined service life of a system of maladjustment. In the end, a numerical example based on operational data of selected aircraft [weapon] sights was presented. The elaborated method can be also applied to determining residual life of shipboard devices whose technical state is determined on the basis of analysis of values of diagnostic parameters.
A fuzzy TOPSIS model to evaluate the Business Intelligence competencies of Port Community Systems

Published: August 2014

Abstract
Evaluation of the Business Intelligence (BI) competencies of port community systems before they are bought and deployed is a vital importance for establishment of a decision-support environment for managers. This study proposes a new model which provides a simple approach to the assessment of the BI competencies of port community systems in organization. This approach helps decision-makers to select an enterprise system with appropriate intelligence requirements to support the managers’ decision-making tasks. Thirtyfour criteria for BI specifications are determined from a thorough review of the literature. The proposed model uses the fuzzy TOPSIS technique, which employs fuzzy weights of the criteria and fuzzy judgments of port community systems to compute the evaluation scores and rankings. The application of the model is realized in the evaluation, ranking and selecting of the needed port community systems in a port and maritime organization, in order to validate the proposed model with a real application. With utilizing the proposed model organizations can assess, select, and purchase port community systems which will provide a better decision-support environment for their business systems.

Published: August 2014

Abstract
Development of nautical tourism in Montenegro, seen as a potentially profitable industry segment has started twenty years ago. The first steps taken in this direction were defining the legal framework, in particular: Law on Coastal Zone, Tourism Master Plan of Montenegro, Law on Yachts, followed by establishment of supporting organizations - Maritime Safety Department of Montenegro, Port Authorities and Border Police Department. Having invested efforts in adoption of planning documents and enactment of legislation relating to nautical tourism in recent period, Montenegro is seeking to impose itself as an important nautical destination. The first serious step towards achieving this goal was construction of a world-class marina Porto Montenegro in Tivat in 2010. The Special Purpose Spatial Plan for Coastal Zone provides for development of network of marinas to be constructed on the Montenegrin Coast. In the light of this, contribution of this paper is reflected in application of multi-criteria optimization in defining an optimum order of marina construction. The paper defines selection of criterion functions from the aspects of ecology, economy, security, specific aspect and aspect of suitability assessment for the location. The paper also presents the process of defining different criterion weights. The multi-criteria analysis determines a compromise solution for marina planning at Montenegrin Coast, which reconciles conflicting interests. The compromise solution is only a proposal, while a final decision remains with a decision maker.

AbstractDeep-sea benthic Ostracoda (Crustacea) in Icelandic waters are poorly known. Here we report deep-sea ostracode assemblages from the multiple core (MUC) and the epibenthic sledge (EBS) samples collected from Icelandic waters by the first cruise of the IceAGE (Icelandic Marine Animals: Genetics and Ecology) project. Samples from shelf-edge and lower-bathyal working areas are examined. The results show (1) distinct MUC and EBS faunas due to the large difference in mesh size of MUC and EBS; and (2) distinct shelf-edge and lower-bathyal ostracode faunas. Such remarkable faunal turnover from shelf to bathyal depths is similar to the faunal turnovers reported from depth transects in the adjacent regions of the western North Atlantic Ocean, the Greenland Sea, and the North Sea, but, at the same time, there are certain differences in the faunal composition between the Icelandic waters and these adjacent regions. In addition, we illustrate many Icelandic deep-sea ostracode species with high-resolution scanning electron microscopy and composite all-in-focus stereomicroscopic images for the first time. These results provide important basic information on deep-sea ostracode research and biogeography of this important region connecting North Atlantic proper and Nordic Seas.
Molecular Species Delimitation of Icelandic Brittle Stars (Ophiuroidea)
Authors: Khodami Sahar , Martinez Arbizu Pedro , Stöhr Sabine , Laakmann Silke 
Published: August 2014

Abstract
Brittle stars (Echinodermata: Ophiuroidea) comprise over 2, 000 species, all of which inhabit marine environments and can be abundant in the deep sea. Morphological plasticity in number and shape of skeletal parts, as well as variable colors, can complicate correct species identification. Consequently, DNA sequence analysis can play an important role in species identification. In this study we compared the genetic variability of the mitochondrial cytochrome c subunit I gene (COI) and the nuclear small subunit ribosomal DNA (SSU, 18S rDNA) to morphological identification of 66 specimens of 11 species collected from the North Atlantic in Icelandic waters. Also two species delimitation tools, Automatic Barcode Gap Discovery (ABGD) and General Mixed Yule Coalescence Method (GMYC) were performed to test species hypotheses. The analysis of both gene fragments was successful to discriminate between species and provided new insights into some morphological species hypothesis. Although less divergent than COI, it is helpful to use the SSU region as a complementary fragment to the barcoding gene.

Published: August 2014

Abstract
During the IceAGE (Icelandic marine Animals – Genetics and Ecology) expeditions in waters around Iceland and the Faroe Islands in 2011 and 2013, visual assessments of habitats and the study of surface sediment characteristics were undertaken in 119–2750 m water depth. Visual inspection was realized by means of an epibenthic sled equipped with a digital underwater video camcorder and a still camera. For determination of surface sediment characteristics a subsample of sediment from box corer samples or different grabs was collected and analyzed in the lab. Muddy bottoms predominated in the deep basins (Iceland Basin, Irminger Basin, deep Norwegian and Iceland Seas), while sand and gravel dominated on the shelves and the ridges, and in areas with high currents. Organic contents were highest in the deep Norwegian and Iceland Seas and in the Iceland Basin, and at these sites dense aggregations of mobile epibenthic organisms were observed. Large dropstones were abundant in the Iceland Sea near the shelf and in the Denmark Strait. The dropstones carried diverse, sessile epibenthic fauna, which may be underestimated using traditional sampling gear. The paper supplies new background information for studies based on IceAGE material, especially studies related to ecology and taxonomy.

Coherently enhanced measurements in classical mechanics
Authors: Braun Daniel , Popescu Sandu 
Published: August 2014

AbstractIn all quantitative sciences, it is common practice to increase the signal-to-noise ratio of noisy measurements by measuring identically prepared systems N times and averaging the measurement results. This leads to a scaling of the sensitivity as 1/√N, known in quantum measurement theory as the “standard quantum limit” (SQL). It is known that if one puts the N systems into an entangled state, a scaling as 1/N can be achieved, the socalled “Heisenberg limit” (HL), but decoherence problems have so far prevented implementation of such protocols for large N. Here we show that a method of coherent averaging inspired by a recent entanglement-free quantum enhanced measurement protocol is capable of achieving a sensitivity that scales as 1/N in a purely classical setup. This may substantially improve the measurement of very weak interactions in the classical realm, and, in particular, open a novel route to measuring the gravitational constant with enhanced precision.
New Aspects of Melasma/Novi aspekti melazme
Authors: Damevska Katerina 
Published: August 2014

Abstract
Melasma is a common cosmetic problem and its severity ranges from minor pigmentation during pregnancy that resolves spontaneously, to a chronic, troublesome, disfiguring condition. Today, there are various treatment modalities for melasma, providing a different success rate. The need for an effective treatment for melasma is becoming more and more significant probably due to the current lifestyles with increased UV exposure, broad use of hormones for contraception and hormone replacement therapy, as well as increasing esthetic demands. The mainstay of treatment is regular use of sunscreens along with topical medications suppressing melanogenesis. This review summarizes recent progress in understanding the pathophysiology of melasma and implications for new treatment strategies.

Published: August 2014

Abstract
Đorđe Đorđević, a Serb from Croatia, was born in Grubišno polje (Croatia) on April 22, 1885. He studied medicine in Vienna and graduated in 1909. Till 1912, he advanced his knowledge working at dermatology clinics with Prof. Finger and Prof. Arning, as well as with Prof. Weichselbaum, professor of pathological anatomy and bacteriology. From 1912 he worked in Zagreb, at the Dermatology Department of the Brothers of Mercy Hospital, and during World War I as a military doctor at the Dermatology Department and the Zagreb Outpatient Department (Second kolodvor). After the war, in 1918, he moved to Belgrade, where he was the Head of the Polyclinic for Skin and Venereal Diseases, and in 1922 he became an Assistant Professor of Dermatology at the School of Medicine in Belgrade. In the same year, he founded the Department of Dermatovenereology at the School of Medicine in Belgrade and the Clinic for Skin and Venereal Diseases, of which he was also the Head. In 1923, he became an Associate Professor, and in 1934 a Full Professor. He is given credit for passing legislation on prostitution and banning brothels.
The professional work of Prof. Đorđe Đorđević encompasses all areas of dermatology, including his special interest in experimental studies in the field of venereology. He organized medical-research trips to study people’s health status, and his teams visited the South Serbia (today Macedonia), Sandžak and Montenegro. In 1927, he founded the Dermatovenereology Section of the Serbian Medical Society (19) and the Association of Dermatovenereologists of Yugoslavia. He was the chairman of the I, II and III Yugoslav Congress of Dermatology in Belgrade, and of the II Congress of the Pan-Slavic Association of Dermatovenereologists with international participation. He was an honorary member of the Bulgarian, Czechoslovakian, Polish and Danish Dermatological Societies, as well as a regular member of the Association of French Speaking Dermatologists, and of French, German and Biology Society. He was the Vice dean of the School of Medicine.
He died suddenly on April 27, 1935, shortly after his 50th birthday, and was mourned by colleagues, friends and students.
On the first anniversary of his death, his family, friends and colleagues established a ”Foundation of Dr. Đorđe-Đurica Đorđević” meant for ”doctors and health workers”. Unfortunately, the foundation was disestablished in the early eighties of the 20th century.
Heat Stress and Thermal Strain Challenges in Running
Authors: Bergeron Michael F. 
Published: August 2014

Synopsis Running well and safely in the heat is challenging for all runners, from recreational to elite. As environmental heat stress (heat stress modulated or augmented by air temperature, humidity, wind speed, and solar radiation) and the intensity and duration of a training run or race increase, so are metabolic heat production, the parallel need for heat transfer from the body to maintain thermal equilibrium, the consequent increase in blood flow to the skin, and the concomitant sweating response progressively and proportionally amplified. An accumulating total body-water deficit from extensive sweating and escalating level of cardiovascular and thermal strain will, in due course, considerably challenge a runner's physiology, perception of effort, and on-course well-being and performance. However, with the appropriate preparation and modifications to planned running intensity and distance, runners can safely tolerate and effectively train and compete in a wide range of challenging environmental conditions. Clinicians play a key role in this regard as an effective resource for providing the most effective guidelines and making the best overall individual recommendations regarding training and competing in the heat.
