Effect of Different Nitrogen Doses on Some Agricultural Characteristics and Alkaloid Content of Hyoscyamus reticulatus L. and Hyoscyamus niger L.
Authors: Kizil S. , Tonҫer Ö. , Sogut T.
Published: July 2017

Alkaloids, nitrogen containing basic substance, have a complex structure. They are one of the most important groups of secondary metabolites, which is synthesized in roots and transported to other organs. Since alkaloids are nitrogenous compounds, the availability of nitrogen is expected to play an important role in the biosynthesis and accumulation of alkaloids in plants. Nitrogen affects yield and quality of medicinal plants, therefore, growers usually apply large amount of nitrogen to obtain high yields. The objective of the present study was to determine yield, yield components and alkaloid content of two henbane species (Hyoscyamus reticulatusL. andHyoscyamus nigerL.), collected from wild flora of South-eastern Anatolia, grown under four nitrogen applications (0, 50, 100 and 200 kg ha−1), in 2010-2011 growing seasons. In the field trial, plant height, stem diameter, number of branches per plant, number of capsule per plant, capsule width, capsule length, number of seed per capsule, 1000 seed weight, seed yield per plant and total alkaloid content were investigated. The results of study showed that nitrogen doses were found important for investigated characters but not important forHyoscyamusspecies. Seed yield per plant varied from 8.4 to 11.6 g per plant, their alkaloid contents were found between 0.14% and 0.21%.
Coronary Artery Malformations Presenting as Acute Coronary Syndromes: A Case Series
Authors: Jani Laura , Hodas Roxana , Beganu Elena , Bordi Lehel
Published: July 2017

Coronary artery malformations are rare congenital abnormalities, which present non-specific symptoms such as atypical chest pain, malignant arrhythmia, or sudden cardiac death. The proper diagnosis of these abnormalities in emergency conditions can be very difficult, and noninvasive imaging techniques, such as computed tomography or magnetic resonance imaging, along with the gold standard represented by invasive coronary angiography, remain the most frequently used modalities for diagnosing these rare cases. We present four cases of coronary anomalies represented by an abnormal origin of the coronary arteries from the coronary ostium, presenting in emergency conditions with symptoms of acute myocardial infarction, which were diagnosed by urgent angiography.

Authors: Szafrański Maciej , Bogurska-Matys Klaudyna , Goliński Marek
Published: July 2017

This paper presents how some communication problems between business and Technical Education System (TES) can be reduced. This comes to a misunderstanding of the needs of entrepreneurs for the knowledge and skills, in this paper treated as a resource on the market. The authors explain why debated issue falls in the area of corporate management. It identifies one of the reasons hindering the solution of problems. In order to clarify the issues it references the achievements of analytic philosophy of language and the theory of communication code. It proposed a method of facilitating the solution of the problem, which is being implemented since 2016 by the research team, co-created by the authors of this publication. The aim of the development of this publication is to supplement the theoretical and practical knowledge of management in manufacturing companies and others with high technical potential, where there is a large, growing and rapidly changing demand for knowledge and technical skills.
Lead Times – Their Behavior and the Impact on Planning and Control in Supply Chains
Authors: Nielsen Peter , Michna Zbigniew , Sørensen Brian Bruhn , Dung Ngoc Do Anh
Published: July 2017

Lead times and their nature have received limited interest in literature despite their large impact on the performance and the management of supply chains. This paper presents a method and a case implementation of the same, to establish the behavior of real lead times in supply chains. The paper explores the behavior of lead times and illustrates how in one particular case they can and should be considered to be independent and identically distributed (i.i.d.). The conclusion is also that the stochastic nature of the lead times contributes more to lead time demand variance than demand variance.
Lean Production Development in SMEs: A Case Study
Authors: Majava Jukka , Ojanperä Tiina
Published: July 2017

The competitiveness of small and medium sized enterprises (SMEs) is vital for the European economy. Also, manufacturing is often the core competence of SMEs. Adopting lean philosophy is a viable and popular approach for developing production and enabling continuous improvement. Despite the increased interest in empirical lean research, the body of knowledge about lean manufacturing development in SMEs is currently insufficient. This paper describes a study of a lean development project in a Finnish-based manufacturing SME. A current state analysis and development proposals are presented. The project applies a framework that other SMEs can utilize in identifying their problem areas and creating development proposals for their production activities. The results of the study contribute to the existing body of knowledge in lean manufacturing. In addition, managers in SMEs can utilize the study results as a reference when designing production development projects.
What Drives Politicians to Run for Office: Money, Fame or Public Service?
Authors: Balian Arpie G. , Gasparyan Arman
Published: July 2017

This is a multiple case study that investigates the motivations and ambitions of politicians who run for elections. It uses a mixed research design that applies inductive reasoning in the collection and analysis of data from six communities of rural Armenia. Data-collection instruments include in-depth interviews, focus groups, field observations and community survey. Whereas the study considers various theories of motivation and ambition, the conclusive evidence shows that the attractiveness of office at the local-government level in smaller rural communities is not driven by financial considerations and is rather compelled by the desire to make a difference motivated primarily by personal interest in and dedication to bringing positive change in the quality of life in one’s own community. The study also shows that motivators oft en stem from several other factors, including one’s deep-rooted connection with the community, lineage, length of term in office, record of community satisfaction, resultant personal power built over the years in service and the need to be acclaimed by one’s own community. A derivative closely linked to the priority of building the personal reputation of an incumbent mayor is the resultant power of decision-making. These conclusions can be explained using the model offered by Besley and Ghatak (2005) where politicians view public service as a personal mission. This study connects personal drive to sense of community and ancestral presence. The study also explains why mission accomplishment is more attractive than personal profit-making and how the sense of community and ownership are linked to personal drive.

Authors: Strzelecki Tomasz , Uciechowska Anna
Published: July 2017

With a view to protecting areas lying near the Nysa Kłodzka river and in order to reduce flood wave in Wrocław Waterway System, construction of a water reservoir near Kamieniec Ząbkowicki is being planned. After analysing the hydrology and hydraulics of the river Nysa Kłodzka and the function of reservoirs in Kamieniec Ząbkowicki cascade, a numerical seepage model, based on finite element method (FEM) and taking into account bedrock geology, drainage design and dam sealing, has been proposed. Boussinesq’s mathematical model was used to calculate unconfined groundwater table and vector field of seepage velocity. Building a numerical terrain model and visualisation of the water table in GIS tools enabled presenting calculation results in 3-D space.
Krankheitsbewertungen von Personen mit chronischen Schmerzerkrankungen und ihr Zusammenhang mit Indikatoren der Spiritualität
Authors: Büssing Arndt
Published: July 2017

Untersucht werden sollte an einem Datensatz von 540 Frauen (Altersmittel 54 ± 13 Jahre) mit chronischen Schmerzerkrankungen, wie sie ihre Erkrankung bewerten und welche Zusammenhänge zwischen negativen und positiven Krankheitsinterpretationen auf der einen und Indikatoren der Spiritualität sowie der Lebensqualität auf der anderen Seite bestehen. Krankheit als sinnlose Unterbrechung fand die meiste Zustimmung, außerdem Krankheit als eine Herausforderung oder als etwas Wertvolles, sowie als Bedrohung und als Hilferuf. Insbesondere die positiven Sichtweisen wurden von Frauen mit einer spirituellen Haltung geteilt und von nichtspirituellen Frauen klar abgelehnt. Als Prädiktoren der negativen Sichtweisen von Krankheit erwiesen sich die Intention, vor Krankheit weglaufen zu können und eine geringe Lebenszufriedenheit, während sich im Regressionsmodell für die positiven und strategieassoziierten Sichtweisen vor allem die Fähigkeit zur Lebensreflexion und eine religiöse Praxis als positive relevante Prädiktoren erwiesen. Eine spirituelle Haltung war also vornehmlich mit der Sichtweise von Krankheit als etwas Wertvolles, an dem man wachsen kann, und als eine Herausforderung assoziiert. Hier stehen möglicherweise die überwindenden und transformierenden Effekte im Vordergrund, die im Sinne eines „inneren Wachstums“ interpretiert werden können.
Large Eddy Simulation of Secondary Flows in an Ultra-High Lift Low Pressure Turbine Cascade at Various Inlet Incidences
Authors: Hu Site , Zhou Chao , Chen Shiyi
Published: July 2017

Increasing the blade loading of a low pressure turbine blade decreases the number of blades, thus improving the aero-engine performance in terms of the weight and manufacture cost. Many studies focused on the blade-to-blade flow field of ultra-high lift low pressure turbines. The secondary flows of ultra-high lift low pressure turbines received much less attention. This paper investigates the secondary flows in an ultra-high lift low pressure turbine cascade T106C by large eddy simulation at a Reynolds number of 100,000. Both time-averaged and instantaneous flow fields of this ultra-high lift low pressure turbine are presented. To understand the effects of the inlet angle, five incidences of ‒10°, ‒5°, 0, +5° and +10° are investigated. The case at the design incidence is analyzed first. Detailed data is used to illustrate the how the fluids in boundary layers develops into secondary flows. Then, the cases with different inlet incidences are discussed. The aerodynamic performances are compared. The effect of blade loading on the vortex structures is investigated. The horseshoe vortex, passage vortex and the suction side corner vortex are very sensitive to the loading of the front part of the blade.
Spatial dynamics of species richness of phytoplankton of Lake Balkhash in the gradient of abiotic factors
Authors: Barinova Sophia , Krupa Elena , Kadyrova Ulrika
Published: July 2017

The spatial distribution of species richness of phytoplankton was studied along the Balkhash Lake water area during the summer of 2004. With statistically weak connections of phytoplankton with environmental parameters, three-dimensional graphs revealed a complex character of its spatial variability in the gradient of environmental factors. Macrophytes had a stimulating effect on the species richness of planktonic algae. We found a correlation between species richness of Cyanobacteria, Chrysophyta, Euglenophyta and Dinophyta and the ionic composition of water. The important role of temperature was traced. Species richness of algal communities increased with increasing temperature in the gradient of nutrients and correlated with the abundance of macrophytes.
Distribution and abundance of Artemia salina in the Salt Lake Basin (Central Anatolia, Turkey)
Authors: Alaş Ali , Kaya Murat , Öktener Ahmet
Published: July 2017

In this study, the distribution and abundance of Artemia salina in 10 different stations of the Salt Lake basin were investigated. In addition, its relationship to pH, dissolved oxygen, temperature, electrical conductivity and water levels were analyzed. Field studies were carried out from July to August of 2010. Artemia salina was observed in five of these stations. Artemia salina was not seen in some stations that have high electrical conductivity. It is determined that, in the station named Tersakan Lake where electrical conductivity was 154 mS/cm, Artemia salina is more abundant when compared to the other stations. But as underground water pumps that are built for the irrigation of agricultural lands decrease water levels, Artemia salina’s life is under threat.
Barbus meridionalis Risso, 1827 populations status in the Vişeu River basin (Maramureş Mountains Nature Park)
Authors: Bănăduc Doru , Curtean-Bănăduc Angela
Published: July 2017

The ecological state of lotic ecosystems occupied naturally by Barbus meridionalis, in the Vişeu Basin within the Maramureş Mountains Natural Park, vary among good to reduced. The inventoried human activities which negatively influence the ecologic state of the Barbus meridionalis species habitats and populations are the organic and mining pollution, and poaching. The habitats with low and inadequate conditions created a reduced status of the Barbus meridionalis populations; the status of Barbus meridionalis populations is not so much affected in the cases of habitats of average to good condition. Barbus meridionalis is considered a relatively common fish species in the researched watershed despite the fact that its populations ecological status has decreased from 2007-2015, but the restoration potential in the area for improving this species status is high.
Effect of Particle Size and Pretreatment on the Conductivity of Glass Powder during Compaction
Authors: Murawski Dawid , Behrens Harald
Published: July 2017

Physical properties of solid materials can be strongly modified by pressure treatment at elevated temperatures. This study focuses on the compaction-induced behavior of powdered amorphous solids using Li2Si3O7-glass as an example. Experiments were carried out on distinct fractions with particle sizes from <25 μm to 224–250 μm. Measurements of electrical conductivity using impedance spectroscopy were carried out in situ at pressures up to 930 MPa and at temperatures from 373 K to 667 K. Simultaneous monitoring of volume changes allows correlating conductivity and porosity of samples. To study the effect of adsorbed water on surfaces, the material was pretreated by flushing with water-bearing nitrogen before the experiment. Continuous increase of electrical conductivity upon pressurization was observed for all particle size fractions both in the brittle and in the plastic deformation regimes. The pressure derivative of DC conductivity strongly increases with grain size at low T (373 K). At high T (608–665 K) the effect is less pronounced due to the onset of welding of particles forming continuous pathways for charge transport without grain boundaries as barriers. Welding of particles occurs already at temperatures significantly below the glass transition temperature, induced by strong local forces at grain-grain contacts. No effect by pretreatment of glass powder with water vapor was observed at low temperature, while at high temperature surface modification by adsorbed water resulted in enhancement of electrical conductivity, probably caused by lowering of viscosity at grain surfaces, which facilitates welding of particles.

Weakley, JJS, Wilson, KM, Till, K, Read, DB, Darrall-Jones, J, Roe, GAB, Phibbs, PJ, and Jones, B. Visual feedback attenuates mean concentric barbell velocity loss and improves motivation, competitiveness, and perceived workload in male adolescent athletes. J Strength Cond Res 33(9): 2420–2425, 2019—It is unknown whether instantaneous visual feedback of resistance training outcomes can enhance barbell velocity in younger athletes. Therefore, the purpose of this study was to quantify the effects of visual feedback on mean concentric barbell velocity in the back squat and to identify changes in motivation, competitiveness, and perceived workload. In a randomized-crossover design (Feedback vs. Control), feedback of mean concentric barbell velocity was or was not provided throughout a set of 10 repetitions in the barbell back squat. Magnitude-based inferences were used to assess changes between conditions, with almost certainly greater differences in mean concentric velocity between the Feedback (0.70 ± 0.04 m·s−1) and Control (0.65 ± 0.05 m·s−1) observed. In addition, individual repetition mean concentric velocity ranged from possibly (repetition number 2: 0.79 ± 0.04 vs. 0.78 ± 0.04 m·s−1) to almost certainly (repetition number 10: 0.58 ± 0.05 vs. 0.49 ± 0.05 m·s−1) greater when provided feedback, whereas almost certain differences were observed in motivation, competitiveness, and perceived workload, respectively. Providing adolescent male athletes with visual kinematic information while completing resistance training is beneficial for the maintenance of barbell velocity during a training set, potentially enhancing physical performance. Moreover, these improvements were observed alongside increases in motivation, competitiveness, and perceived workload providing insight into the underlying mechanisms responsible for the performance gains observed. Given the observed maintenance of barbell velocity during a training set, practitioners can use this technique to manipulate training outcomes during resistance training.
Figuring the Population Explosion
Authors: McCann Carole R.
Published: July 2017

In 1959 CBS Reports presented the population explosion to viewers as a crisis whose ingredients were statistical. Conceptualizing quantification as a socially situated media practice, this article interrogates the history of the production and circulation of the demographic data and the iconic figures that brought the population crisis to life. The analysis exhumes the intertwined quantitative contingencies and affective associations in three demographic formations: the calibration of natural fertility and pregnancy risk that naturalized fertility as an excessive feature of “other” women's bodies; accounts of population dynamics haunted by racialized feminine figures of natural excess and cultural incompetence; and population projection procedures that elided mortality and amplified the effects of fertility on population growth and economic development. The resulting figures, deployed by US demographers in a concerted media campaign, provoked a mathematical panic about global futures that moved nations to intervene in women's reproductive lives.
Geostrategijski aspekt demografske dinamike Sandžaka

Published: July 2017

The paper studies the importance of demographic processes on the territory of Sandžak in the period of 1948-1991 in the context of demographic causes of Great-Serbian aggression against Croatia and Bosnia and Herzegovina in 1991 and Serbian military activities in Kosovo and south-east of Serbia (Preševo and Bujanovac districts).It has been presumed that the religious and national structure of Sandžak with a further trend of the increase of absolute number and relative share of Moslems and decreasing number of Serbians and Montenegrins, as well as considering its geostrategic importance to Serbian and Montenegrin interests then those of international power centres, will continue to be the causal space of potential crises and war conflicts not only in the quoted country but in the larger region too. As it is a question of nearer Croatian security environment, the territory of Sandžak is important also from the viewpoint of national security of the Republic of Croatia.

Prirodna obilježja hrvatskog litoralnog prostora kao komparativna prednost za razvoj nautičkog turizma
Authors: Favro Srećko , Saganić Iva
Published: July 2017

Having in mind Croatian littoral area with its unique attractive coast and islands, it can be said that nautical tourism is absolutely authentic and distinctly recognizable Croatian "tourist product". In spite of numerous comparative advantages, Croatian nautical tourism still has not taken the right place on the market of Mediterranean nautical tourism. Future development of nautical tourism with its complementary activities – nautical economy, should be considered as the driving force for social and economic development of Croatian coastal area and islands, and it should be correctly dimensioned in accordance with carrying capacity of the geographical basis and sustainable development principles. Adequate valorization of Croatia’s most important resources, coast and islands, based on sustainable development principles and long-term systematic actions would improve social and economic position of Croatian Adriatic area.
Populacijski razvoj Zadra
Authors: Graovac Vera
Published: July 2017

Zadar is one of the cities with longest urban tradition and continuous population in Croatia. This article deals with the number of inhabitants in Zadar throughout the history, particularly from 15th century on, when first censuses were taken. Until the second half of 20th century, the population growth was slow and depended mostly on numerous wars, economic conditions, epidemics and famines that caused massive death and migrations of the population within the city and in its surroundings. It was only after the Second World War that population growth was rapid, due to industrialization and stronger economic development of the town.
"Tabvla Sinvs Venetici" W. Barentsa i njeno povijesnozemljopisno značenje
Authors: Kozličić Mithad
Published: July 2017

Two variants of navigational map of the Adriatic made by the Dutch seaman and polarexplorer Willem Barents are known in the scientific literature. The first one, in this article marked K-1, was worked out and printed in Amsterdam in 1595. Its primary function was practical-related to navigation. Opposite to it, K-2, which we date 1595 (1637-1662), was used as the geostrategical map of the Adriatic and the southern parts of Europe. Namely, owing to the Turkish penetrations since the middle of the 16th century, essential military and political changes occured on the northern coasts of the Adriatic sea and specially in their hinterlands. Just such a map was in want in "Atlases" of Jan (Johann, Ioannes) Janssonius (1588-1664) which were printed several times also in Ammsterdam but in the period from 1637 to 1662. Barents’ K-1, which was at Janssonius’ disposal, could fulfil this function. So Janssonius made only the most indispensable changes in accordance with the cartography of the first half of the 17th century and printed it. In this way K-2 lost its primarily practical-navigational function and assumed the characteristics of a map with essential strategical elements. This article deals with these fundamental questions of K-1 and K-2.

Zadarski akvatorij u Pîrî Reisovoj Knjizi pomorstva iz 1526. godine: Pomorsko-geografske slike dijela hrvatskoga Jadrana
Authors: Kozličić Mithad , Mlinarić Dubravka , Andrić Marta
Published: July 2017

U radu su analizirane karte i tekstualni geografski opisi (peljar) zadarskog akvatorija iz djela Kitâb-ı Bahriye (Knjiga pomorstva) osmanskog moreplovca, pirata i kasnije admirala Pîrî Reisa. Komparativnom analizom sravnjeno je više primjeraka toga plovidbenog priručnika iz dosad poznatih istanbulskih izvora, ali i manje poznati primjerak iz Umjetničkog muzeja Walters (Walters Art Museum) u Baltimoru. Cilj je bio usporediti saznanja koja su o širem zadarskom prostoru posredstvom skrovitog rada stranca iz neprijateljskih redova, Pîrî Reisa, dobili Osmanlije u odnosu na radove suvremenih mu mletačkih kartografa, kao “domaćina” na istočnoj jadranskoj obali. Preispitivanje njegova rada iz povijesno kartografske ali i imagološko-geografske perspektive pokazuje da je uspio izbalansirati potrebu za nastankom navigacijski i geografski iznimno kvalitetnog materijala s vlastitom pozicijom stranca na istočnom Jadranu. Kartografske i narativne slike Pîrî Reisa o zadarskom akvatoriju predstavljaju odraz dosega i mogućnosti osmanske kartografije što omogućuje njezino preispitivanje. Razlog leži u činjenici da kvaliteta kartografskog i narativnog dijela produkcije Pîrî Reisa nije dosegnuta u onodobnim plovidbenim priručnicima. Korištena toponimija upućuje na to da se Pîrî Reis služio tuđim dostupnim izvorima, primjerice uputama za plovidbu, ali ih je kombinirao s brojnim vlastitim opažanjima. Stoga njegov rad predstavlja posve izvoran opis zadarskog akvatorija, koji zbog obilja novih podataka donosi potpuno nove znanstvene spoznaje.
Socio-geografska preobrazba Mostarskog blata
Authors: Miličević Mirjana
Published: July 2017

This paper analyzes the process of socio-geographic transformation of rural settlements in Mostarsko Blato, karst polje in the Neretva River drainage area. Many changes in spatial organization and landscape have been determined by deagrarization and deruralization, which had been, on the other hand, influenced by various geographic factors: neighboring towns, inadequate infrastructure, profound changes in job offers related to the problems of economic development at the end of socialist period and in transitional period, and particularly by Serbian aggression on Croatia and Bosnia and Herzegovina.Despite numerous problems, socio-economic development of Mostarsko Blato is possible due to natural and human resources. Its development should be based on organic farming, and on development of different types of tourism (ecologic, rural, camping, fishing and summer tourism).
Vikendice na otoku Krku - prostorni raspored i strukturna obilježja vlasnika
Authors: Opačić Vuk Tvrtko
Published: July 2017

The period of the conversion of the existing and abandoned residential dwellings into second homes (mostly in 1960s and 1970s) on the island of Krk, as well as along the whole stretch of the Croatian littoral, was followed by the period of the construction of purpose-built dwellings for vacation and recreation, i.e. of family weekend-houses (in 1970s and 1980s). This was manifested through the purchase and conversion of agricultural land into building sites which initially targeted the most desirable locations along the coast of the island, and later less desirable locations in the island hinterland. From mid 1990s onwards the island of Krk, and especially certain parts of it, experienced a more intensive construction of multi-apartment buildings for vacation and recreation which brought about radical geographical transformation. The study analyses the characteristics of the recent developmental dynamics of the second home phenomenon on the island of Krk as a representative case study of a receiving second home region within the Croatian littoral. The study is based on the analysis of the spatial distribution of dwellings for vacation and recreation and the comparison of their number with the number of dwellings for permanent occupancy. In order to achieve a more accurate picture of the intensity and directions of the second home mobility which exists among emissive and receiving second home regions, an analysis is provided of the structural characteristics of the owners of second homes on Krk. They are grouped by the place of their permanent residence, the distance between the place of permanent residence and the receiving second home region and by the size of the place of permanent residence.

Although the Velebit is a low mountain situated in the moderate climate zone, there exist periglacial processes in relief modelling in its highest part. The reason for this is interdependance of geological, geomorphological, climatic, vegetational and pedological influences, but also long antropogenic and zoogenic influences. Among periglacial forms the features which originated from the activity of nival and frost processes can be singled out.
Geografski aspekt proučavanja trajektnog prometa: primjer hrvatskog otočja
Authors: Opačić Vuk Tvrtko
Published: July 2017

This paper deals with the importance of the spatial, geographic aspect in analyzing ferry traffic, especially on Croatian islands. The importance of ferry traffic is analyzed within the regional development of the European Union as a whole, as well as through some examples from different states. The analytical part of the paper deals with correlation between the ferry traffic and its two most striking indirect consequences that are present on Croatian islands, and those are demographic development and tourism. There is a close, direct connection between ferry traffic and tourism, as well as between ferry traffic and general demographic trends. Since there is no evidence of correlation between the index of seasonal frequency of the ferry lines (direct reflection of tourism) and the index of change in population trends on Croatian islands analyzed in this paper, the conclusion is that tourism, as the main economic activity on Croatian islands, can ease – but not significantly eliminate – depopulation characteristics of the insular part of Croatia.
Taking Stock of the Drosophila Research Ecosystem
Authors: Bilder David , Irvine Kenneth D
Published: July 2017

With a century-old history of fundamental discoveries, the fruit fly has long been a favored experimental organism for a wide range of scientific inquiries. But Drosophila is not a “legacy” model organism; technical and intellectual innovations continue to revitalize fly research and drive advances in our understanding of conserved mechanisms of animal biology. Here, we provide an overview of this “ecosystem” and discuss how to address emerging challenges to ensure its continued productivity. Drosophila researchers are fortunate to have a sophisticated and ever-growing toolkit for the analysis of gene function. Access to these tools depends upon continued support for both physical and informational resources. Uncertainty regarding stable support for bioinformatic databases is a particular concern, at a time when there is the need to make the vast knowledge of functional biology provided by this model animal accessible to scientists studying other organisms. Communication and advocacy efforts will promote appreciation of the value of the fly in delivering biomedically important insights. Well-tended traditions of large-scale tool development, open sharing of reagents, and community engagement provide a strong basis for coordinated and proactive initiatives to improve the fly research ecosystem. Overall, there has never been a better time to be a fly pusher.

Closing the gap: the potential of Christian Health Associations in expanding access to family planning
Authors: VanEnk Lauren , Kasyaba Ronald , Kanani Prince Bosco , Tumwesigye Tonny , Cachan Jeannette
Published: July 2017

Recognizing the health impact of timing and spacing pregnancies, the Sustainable Development Goals call for increased access to family planning globally. While faith-based organizations in Africa provide a significant proportion of health services, family planning service delivery has been limited. This evaluation seeks to assess the effectiveness of implementing a systems approach in strengthening the capacity of Christian Health Associations to provide family planning and increase uptake in their communities.
From January 2014 to September 2015, the capacity of three Christian Health Associations in East Africa—Caritas Rwanda, Uganda Catholic Medical Bureau, and Uganda Protestant Medical Bureau—was strengthened with the aims of improving access to women with unmet need and harmonizing faith-based service delivery contributions with their national family planning programs. The key components of this systems approach to family planning included training, supervision, commodity availability, family planning promotion, data collection, and creating a supportive environment. Community-based provision of family planning, including fertility awareness methods, was introduced across intervention sites for the first time. Five hundred forty-seven facility- and community-based providers were trained in family planning, and 393,964 people were reached with family planning information. Uptake of family planning grew substantially in Year 1 (12,691) and Year 2 (19,485) across all Christian Health Associations as compared to the baseline year (3,551). Cumulatively, 32,176 clients took up a method during the intervention, and 43 percent of clients received this service at the community level. According to a provider competency checklist, facility- and community-based providers were able to adequately counsel clients on new fertility awareness methods. Integration of Christian Health Associations into the national family planning strategy improved through participation in routine technical working group meetings, and the Ministries of Health in Rwanda and Uganda recognized them as credible family planning partners. Findings suggest that by strengthening capacity using a systems approach, Christian Health Associations can meaningfully contribute to national and international family planning goals. Increased attention to community-based family planning provision and to mainstreaming family planning service delivery across Christian Health Associations is recommended.

Fukoidan merupakan polisakarida sulfat yang mengandung L-fukosa dan sulfat. Fukoidan diperoleh dari hasil ekstraksi rumput laut coklat Sargassum crassifolium yang berasal dari Binuangeun, Banten. Fukoidan diekstrak dari rumput laut kering menggunakan HCl 0,1N dan diendapkan dengan menggunakan CaCl2 selanjutnya dimurnikan dengan kromatografi kolom mengunakan resin Sephadex A-25 dan diperoleh rendemen 0,87%. Karakterisasi fukoidan dilakukan melalui uji penentuan berat molekul, kandungan sulf at, penentuan monosakarida penyusun fukoidan, dan uji aktivitas antikoagulan. Hasil karakterisasi menunjukkan bahwa fukoidan memiliki berat molekul 7,71 x 104 Dalton, kadar sulfat tertinggi sebesar 8,55 ppm, monosakarida penyusun berupa fukosa dan galaktosa dengan rasio mol 1,0 : 1,5. H asil uji bioaktivitas sebagai antikoagulan pada plasma darah manusia secara in vitro dilihat dari perpanjangan nilai APTT menunjukkan perbedaan signifikan antara kontrol dengan darah yang mengandung fukoidan pada konsentras i 100 µg/mL (berbeda 25 detik). Hal ini mengindikasikan bahwa fukoidan berpotensi sebagai antikoagulan.

This paper examines how mapping technology is central to the operation of the United States Border Patrol security apparatus on the US/Mexico Border, and explores how the very same mapping technology can be used in critique this security project. Drawing on the concept of counter-mapping, we use spatial data collected by the Undocumented Migration Project – a long-term anthropological project aimed at understanding various elements of the violent social process of clandestine migration between Latin America and the United States – to critique the spatial ideology of PTD and the technological conditions of its production.

The TGF-β and Wnt/β-catenin pathways have important roles in modulating CKD, but how these growth factors affect the epithelial response to CKD is not well studied. TGF-β has strong profibrotic effects, but this pleiotropic factor has many different cellular effects depending on the target cell type. To investigate how TGF-β signaling in the proximal tubule, a key target and mediator of CKD, alters the response to CKD, we injured mice lacking the TGF-β type 2 receptor specifically in this epithelial segment. Compared with littermate controls, mice lacking the proximal tubular TGF-β receptor had significantly increased tubular injury and tubulointerstitial fibrosis in two different models of CKD. RNA sequencing indicated that deleting the TGF-β receptor in proximal tubule cells modulated many growth factor pathways, but Wnt/β-catenin signaling was the pathway most affected. We validated that deleting the proximal tubular TGF-β receptor impaired β-catenin activity in vitro and in vivo. Genetically restoring β-catenin activity in proximal tubules lacking the TGF-β receptor dramatically improved the tubular response to CKD in mice. Deleting the TGF-β receptor alters many growth factors, and therefore, this ameliorated response may be a direct effect of β-catenin activity or an indirect effect of β-catenin interacting with other growth factors. In conclusion, blocking TGF-β and β-catenin crosstalk in proximal tubules exacerbates tubular injury in two models of CKD.
Effect of Cytochrome P450 Metabolites of Arachidonic Acid in Nephrology
Authors: Fan Fan , Roman Richard J.
Published: July 2017

Thirty-five years ago, a third pathway for the metabolism of arachidonic acid by cytochrome P450 enzymes emerged. Subsequent work revealed that 20-hydroxyeicosatetraenoic and epoxyeicosatrienoic acids formed by these pathways have essential roles in the regulation of renal tubular and vascular function. Sequence variants in the genes that produce 20-hydroxyeicosatetraenoic acid are associated with hypertension in humans, whereas the evidence supporting a role for variants in the genes that alter levels of epoxyeicosatrienoic acids is less convincing. Studies in animal models suggest that changes in the production of cytochrome P450 eicosanoids alter BP. However, the mechanisms involved remain controversial, especially for 20-hydroxyeicosatetraenoic acid, which has both vasoconstrictive and natriuretic actions. Epoxyeicosatrienoic acids are vasodilators with anti-inflammatory properties that oppose the development of hypertension and CKD; 20-hydroxyeicosatetraenoic acid levels are elevated after renal ischemia and may protect against injury. Levels of this eicosanoid are also elevated in polycystic kidney disease and may contribute to cyst formation. Our review summarizes the emerging evidence that cytochrome P450 eicosanoids have a role in the pathogenesis of hypertension, polycystic kidney disease, AKI, and CKD.
Constitutional law and international law at the turn of the century
Authors: Frowein JA
Published: July 2017

Constitutional law and international law operate in simultaneous conjunction and reciprocal tension. Both fields seem to have overcome the great challenges of destruction and neglect in the course of the 20th century. 

Both after World War I and World War II the world experienced new waves of constitution making. In both cases the current German constitutions (the Weimar Constitution of 1919 and the Grundgesetz of 1949) were influential. 

Characteristic of constitution-making in this century, is the final victory of liberal constitutions based on the rule of law, the Rechtsstaat, fundamental rights, meaningful control of public powers and the establishment of constitutional courts. 

Following the destruction of World War II, the notion of the Sozialstaat emerged strongly in Germany. In contrast to the Constitution of the United States of America, the principle of the responsibility of the state for social justice has emerged in almost all new constitutions, including Russia, Poland, South Africa, Spain, Italy and Portugal. 

Where courts are given the mandate to interpret bills of rights, fundamental rights have been developed into foundation stones of the legal system. The presence in a Bill of Rights of restrictive clauses, is important for its analysis. Generally restrictive clauses in new constitutions try to limit the possibilities of restriction. 

The importance of constitutional rules establishing and legitimizing the political organs, must not be overlooked. Of particular importance is the degree of control over the head of state, a positive attitude among political actors towards the constitution and the protection of the interests of minorities in a democratic system. 

In the field of Public International Law much of Kant's ideal of an international confederation of peace has been realized. Since 1990 the United Nation's Security Council has shown the potential of becoming a directorate for the community of

nations. 

International law has also been instrumental in the worldwide recognition of human rights. Especially in Europe, Convention Law has had a strong impact. Furthermore, global and regional systems of regulation have tended to alter the legal attitude towards state sovereignty. It may be that the South African constitutional approach in terms of which international law is subject to constitutional and other national law, is not in line with international tendencies.
The best of both worlds? some reflections on the interaction between the common law and the Bill of rights in our new constitution
Authors: O'Regan Kate J

The relationship between the Bill of Rights in the South African Constitution of 1996 and the common law is analyzed in this paper. "Common law" is understood broadly to include not only the Roman-Dutch law, but also the wide variety of legal sources and traditions which make up South African law, including African tradition, Muslim practice and the English law heritage.

Firstly an exposition of the chief characteristics of the hybrid system of South African common law is given. It is shown that the common law is not codified; that it is a living and organic system of law constantly under legislative and judicial review; that its sources vary from judicial precedent to civilian authorities, English, indigenous customary and Muslim law; that the style of litigation and adjudication is English rather than Continental in Character and that when a common law rule is modified, it is done retrospectively in conflict with principles of legal certainty.

Secondly the chief constitutional provisions relating to the relationship between the Constitution and the common law are considered. The supremacy clause (section 2) renders a common law rule which is inconsistent with the Constitution invalid from the date of the Constitution unless a court gives a different ruling in accordance with justice and equity. Courts have the inherent power to develop the common law, but the Constitutional Court may do so only in constitutional matters. Two forms of constitutional normative effects may be distinguished: direct (as in sections 2 and 8(1)) and indirect (as in section 39(2)). In terms of the latter the spirit, purport and objects of the Bill of Rights are to guide the development of the common law.

Thirdly the interaction between the common law and the Constitution is thoroughly explored with reference to common law rules that are in conflict with the Constitution as well as where the common law already provides protection for the rights provided by the Bill of Rights. These matters are explored with reference to a number of recent judgments of the Constitutional Court, in some of which the common law was effectively developed.

It is concluded that the firm normative thrust of the Constitution may well prove to be a rich source of principle for the development of the common law and that the flexibility of the common law may facilitate a cross-pollination between it and the Constitution.
