Published: July 2017

The existence and distribution of plants on the earth with one of the most important elements of the natural environment are determined by the abiotic and biotic conditions. Changes that occur in natural conditions and human activities are generally creating a negative effect and many plant species are facing in danger of extinction. One of these conditions, climate is main factor that directly affects the lives of plants and determines the existence and distribution of vegetation as globally, regionally and locally.The greenhouse effect caused by human activities in the last century and the global climate change can have impacts on the existence and spatial changes of plants. In this context, the effects of temperature conditions as the main factor on vegetation are examined according to the certain temperature values and duration. Mean daily temperature values of meteorological stations, which have long term observation record, in the study area, were analyzed statistically. As a result, dates of start, dates of finish and number of days and temporal changes of vegetation period are determined in this period.Extended English abstract is in the end of PDF (TURKISH) file.ÖzetDoğal ortamın en önemli unsurlarından olan bitkilerin varlığını ve yeryüzündeki dağılışını abiyotik ve biyotik koşullar belirlemektedir. Doğal koşullarda meydana gelen değişimler ve insan faaliyetleri, genellikle olumsuz etki yaratmakta ve birçok bitki türünün nesli tükenme tehlikesiyle karşı karşıya kalmaktadır. Bu koşullar içerisinde iklim doğrudan bitki yaşamını etkileyen ana faktör durumunda olup küresel, bölgesel ve yerel olarak vejetasyon topluluklarının varlığını ve mekânsal dağılışını belirlemektedir.Son yüzyılda insan faaliyetlerine bağlı olarak ortaya çıkan sera etkisi ve küresel iklim değişimi bitkilerin varlığı ile mekânsal değişimi üzerinde etkili olabilmektedir. Bu çerçevede, vejetasyon üzerinde ana etken durumunda olan sıcaklık koşullarının bitkiler üzerindeki etkisi, belirli sıcaklık değerleri ve süresine göre ele alınıp incelenmiştir. İnceleme alanında uzun dönem gözlem kaydı bulunan meteoroloji istasyonlarının günlük ortalama sıcaklık verileri istatistiki olarak analiz edilmiştir.

Authors: Stasiak Andrzej
Published: July 2017

Globalization leaves its footprint on the leisure market contributing to the global popularization of brand new forms of recreation. A perfect example of such instant diffusion of innovation on a global scale is the rapid development of escape rooms. The aim of the article is to try and explain the extraordinary popularity of escape rooms in Poland, mainly through an analysis of what they offer. The author presents the origins and development of this particular form of recreation, discusses the location of nearly 600 facilities functioning in 2016, as well as giving a detailed description of escape rooms in the ten large Polish cities. The study leads to the conclusion that the phenomenon of escape rooms stems from, among other things, the fundamental assumptions of the experience economy.
European integration perspectives: From cohesion to divergence?
Authors: Recher Vedran , Kurnoga Nataša
Published: July 2017

This paper examines the impact of EU enlargement and the global economic crisis on the relative development of the EU countries. This effect is assessed by applying multivariate analysis to the whole set of 28 European countries at three representative points in time. The cluster analysis for the years 2002, 2007, and 2012 grouped the countries according to the range of economic development indicators showing within-EU cohesion before the EU enlargement, after the enlargement wave, and after the crisis. The findings show that a decrease in the development differences after the enlargement was replaced with an increase in these differences after the crisis, thus contributing to the existing debate about the success of cohesion and future of European integration. These results are somewhat worrying for the new member states of the EU as well as for EU membership candidates and their prospective development within the integration.

Published: July 2017

Conjugated polymers have been proposed as promising materials for scaffolds in tissue engineering applications. However, the restricted processability and biodegradability of conjugated polymers limit their use for biomedical applications. Here we synthesized a block-co-polymer of aniline tetramer and PCL (AT–PCL), and processed it into fibrous non-woven scaffolds by electrospinning. We showed that fibronectin (Fn) adhesion was dependent on the AT–PCL oxidative state, with a reduced Fn unfolding length on doped membranes. Furthermore, we demonstrated the cytocompatibility and potential of these membranes to support the growth and osteogenic differentiation of MC3T3-E1 cells over 21 days.

Synthesis and prediction of transport properties of hybrid bilayer ion-exchange membranes
Authors: Filippov Anatoly N , Kononenko Natalia A , Afonin Denis S , Vinokurov Vladimir A
Published: July 2017

Bilayer membranes consisting of a thick layer of a pure perfluorinated membrane MF-4SC and a thinner layer of the same membrane modified by halloysite nanotubes (HNTs), functionalized with platinum nanoparticles, are investigated. Membrane synthesis was carried out by casting from a polymer solution followed by drying. One of the samples revealed a weak asymmetry of diffusion permeability and the current–voltage characteristic. By using the physicochemical characteristics of monolayer membranes obtained earlier, the dependence of the diffusion permeability of the bilayer composite on the electrolyte concentration is described with satisfactory accuracy. The numbers of water transport and the selectivity of hybrid membranes, and their power characteristics in the membrane–electrode block of the fuel cell, were studied. The introduction of halloysite leads to a decrease in both parameters, and the subsequent addition of platinum compensates for the negative effect of halloysite addition: the maximum specific power becomes higher than that for the original/pure membrane, and the range of operating current densities widens. This makes it possible to predict the effective use of hybrid membranes based on MF-4SC and HNTs with platinum nanoparticles, not only as separating diaphragms in fuel cells and electromembrane devices, but also as promising catalytic systems.

Published: July 2017

Background: Liver abscess has shown a major change in demographics, etiology, diagnosis, and treatment over the past 100 years. The modern diagnostics like ultrasound and computed tomography to locate and drain the abscess have reduced the mortality to 2-12%. However, due to the complications of liver abscess especially the amebic ones the morbidity is still high. This study aims to study the correlation of various LFT parameters with abscess volume for early detection of high risk patients and early treatment thus reducing morbidity.Methods: The study was conducted over a period of 6 months on 50 patients of liver abscess. History and physical examination was done. All patients were subjected to complete hemogram, liver function test, coagulation profile (PT/INR) and USG abdomen. The data was recorded and compiled in excel sheets and analyzed using correlation coefficient (R) method.Results: The mean age of the patients was 41.2 years with male preponderance. Amoebic liver abscess (88%) was predominant over pyogenic liver abscess (12%). Alcoholism (48%), smoking (42%) and diabetes mellitus (18%) are main predisposing factors in case of liver abscess. Hepatomegaly was found in 88% cases. Elevated ALP, low albumin, increased PT INR points to the diagnosis of liver abscess. Complications seen were pleural effusion (10%) and ascites (4%). On analysis, liver abscess size is significantly positively correlated with INR, ALP, liver enzymes, and negatively correlated with serum albumin level.Conclusions: Liver abscess size was found to be positively correlated with INR and alkaline phosphatase (ALP), liver enzymes (SGOT, SGPT) and negatively correlated with serum albumin levels. There was no correlation of abscess size and bilirubin levels. Hence, LFT can be used to estimate the liver abscess size and predict the severity and prognosis of patient.
A Technology for Reduction of Phenol Containing Waste Water and Power Consumption in Phenol and Acetone Plants
Authors: Popov N.T. , Iovtchev S.T. , Marinov M.I.
Published: July 2017

The aim of this paper is to present a new concept for separation of a reaction mixture (RM) that is result of degradation of cumenehydroperoxide in industrial plants. Except the main components - phenol and acetone, this mixture contains water and a great number of different compounds, which form a lot of azeotropic mixtures. The separation of RM is difficult, power consuming and is impossible to occur without chemisorption. The proposed method has been implemented in the Phenol plant - “LUKoil Neftochim” in Bourgas, Bulgaria. The difference between the new and the existing technologies is that the main quantity of phenol, presenting in so-called acetone stream, is removed from the bottom of the first column for acetone purification and then it goes back for dilution of the reaction mixture. The application of this method reduces at least by half the quantity of phenol containing waste water and the expenses for the water regeneration: NaOH, H2SO4, steam, cooling water, electric power, etc. It lowers the consumption of steam and cooling water as a result of usage of partial condensers at first two columns. The quality of the finished acetone is improved too.

Delphi Expert Survey on Climate Policies, Plans/Strategies in Nepal
Authors: Maharjan Shree K. , Maharjan Keshav L.
Published: July 2017

The government of Nepal (GoN) has developed and implemented climate policies, plans and frameworks such as NAPA, National Climate Change Policy, LAPA and currently in the process of developing National Adaptation Plans (NAPs). These policies and plans are in different states of its implementation with diverse opinions and perceptions of the stakeholders. The paper has explored these opinions and experiences of climate experts in Nepal on state of climate policies, inter-linkages, roles and responsibilities of ministries/departments, important factors and subjective indicators for effective implementation of the policies. Altogether 30 experts responded the questionnaire sent via the email, LinkedIn and Skype Interview in the 1st phase of Delphi research technique. The experiences of these experts range from 2-30 years representing government, non-government sectors, media and independent experts. As per most of the experts interviewed, the policies and plans are progressing in strategic direction with national and local priorities. The LAPA is the pioneer framework to address the local climatic issues, originated in Nepal. However, lack of clarity on roles/responsibilities and coordination among the ministries/departments; clear mechanisms for implementation of these policies; lack of sensitization, decentralization and delegation of finance and technologies; capacity of the stakeholders are the major challenges identified.

Multilevel method to compute the lambda modes of the neutron diffusion equation
Authors: Carreño A. , Vidal-Ferrándiz A. , Ginestar D. , Verdú G.
Published: July 2017

Determination of the reactor kinetic characteristics is very important for the design and development of a new reactor system. In this sense, the computation of lambda modes associated to a nuclear power reactor has interest since these modes can be used to analyze the reactor criticality and to develop modal methods to analyze transient situations in the reactor. In this paper, the lambda problem has been discretized using a high order finite element method to obtain a generalized algebraic eigenvalue problem. A multilevel method is proposed to solve this generalized eigenvalue problem combining a hierarchy of meshes with a Modified Block Newton method. The Krylov-Schur method is used to compare the efficiency of the multilevel method solving several benchmark problems.
A Phase-Behavior Study for n-Hexane/Bitumen and n-Octane/Bitumen Mixtures
Authors: Gao Jianyi , Okuno Ryosuke , Li Huazhou Andy
Published: July 2017

Steam/solvent coinjection has been studied as a potential method to improve the efficiency of conventional steam-assisted gravity drainage (SAGD) for bitumen recovery. This research is part of an experimental program for phase behavior of Athabasca-bitumen/solvent mixtures.

This paper presents a new set of experimental data for phase equilibrium, viscosity, density, and asphaltene precipitation for 11 mixtures of Athabasca bitumen with n-hexane and 10 mixtures of the same bitumen with n-octane. Phase-boundary measurements were conducted at temperatures up to 160°C and pressures up to 10 MPa. The bitumen sample used in this research was studied in our previous research, in which the same bitumen was not effectively diluted by n-butane because of the coexistence of a butane-rich liquid with a bitumen-rich liquid phase.

In this research, the liquid/liquid separation of hydrocarbons was not observed for n-hexane/bitumen (HB) and n-octane/bitumen (OB) mixtures for the range of temperatures and pressures tested, even at solvent concentrations higher than 90 mol%. This observation indicates that the amount of solvent available near the edge of a steam chamber is expected to be entirely used for bitumen dilution beyond the chamber edge in coinjection of steam with heavier hydrocarbon solvents, such as n-hexane and n-octane.

Experiments for asphaltene precipitation at atmospheric pressure showed a larger amount of precipitates with n-hexane than with n-octane at a given solvent concentration higher than 50 wt%. For solvent concentrations less than 50 wt%, no asphaltene precipitation was observed for both solvents with the bitumen sample tested in this research.

Published: July 2017

Background/Aim. Disruption of cerebral venous blood drainage leads to cerebral venous congestion, an increase in intracranial pressure and decrease of the cerebral perfusion pressure. The exact role of the cerebral venous circulation in acute stroke is not yet known. The main blood drainage from the brain and the superficial parts of the face and neck is drained by a paired internal jugular vein (IJV). Congenital anomalies of IJV may disrupt the blood collection from the brain, which leads to congestion of the cerebral venous circulation. The aim of our study was to determine the association between the hypoplastic ipsilateral IJV and clinical outcome of patients with acute ischemic anterior circulation stroke. Methods. This prospective case series study involved the patients with the anterior circulation stroke and ultrasonographic criteria for unilateral hypoplasia of the ipsilateral IJV. Data from the 74 consecutive patients with acute anterior circulation stroke admitted to the Special Hospital for Cerebrovascular Diseases ?Sveti Sava?, Belgrade, from September 2015 to January 2016 were included. Ultrasonography of IJV diameter and the collection of the hemodynamic data were performed in all patients. Neurological deficits on admission were evaluated using the National Institutes of Health Stroke Scale (NIHSS) score. The clinical outcome was assessed using the modified Rankin Scale (mRS) score (from 0 to 6) at 30 days or at discharge, whichever occurred sooner. Good and poor outcomes were defined as an mRS score of 0?2 and 3?6, respectively. Results. Ipsilateral hypoplastic IJV was diagnosed in 13 (17.6%) patients with anterior circulation stroke. In this group, 9 stroke patients (69.2%) had mRS ? 3. Of the remaining 4 patients with mRS ? 2, three had bilateral hypoplasia of IJV and one patient had smaller diameter of the IJV, but did not fulfill the ultrasonographic criteria for hypoplastic venous anomaly. Conclusions. In our case, a series of the patients with anterior circulation stroke with ultrasonographic criteria for unilateral hypoplasia of the ipsilateral IJV (on stroke side) have worse clinical outcome compared with the patients with bilateral hypoplasia.

In this work we show the influence of the edge-effect on the electric field distribution, and hence on inner capacitance and outer capacitance of the inclined angle, of a inclined-plate capacitor system in a plane, surrounded by an insulating medium taking into account the thickness of the conducting plates for a complete set of dimensions and insulating characteristics. Where available we compare our results with previous published works. Finally, using statistical tools, we obtain the expression for computing the relationship between capacitance and insulation characteristics, insulation gap, plate dimensions and inclined angle.
Environmental/Economic Power Dispatch of MicroGrid Using Multiobjective Optimization
Authors: Faisal A. Mohamed  , Heikki N. Koivo
Published: July 2017

This paper proposes a generalized formulation to determine the optimal operating strategy and cost optimization scheme as well as the reduction of the emissions for a MicroGrid (MG). Multiobjective (MO) optimization is applied to the environmental/economic problem of the MG. The proposed problem is formulated as a nonlinear constrained MO optimization problem. Prior to the optimization, models for system components from real data are constructed. The problem formulation takes into consideration the operation and maintenance costs as well as the emissions NOx, SO2, and CO2 reduction. The MG considered in this paper consists of a wind turbine, a micro turbine, a diesel generator, a photovoltaic array, a fuel cell, and a battery storage. The optimization is aimed at minimizing the cost function of the system while constraining it to meet the costumer demand and safety of the system. We also add a daily income and outgo from sale or purchased power. The results demonstrate the efficiency of the proposed approach to satisfy the load and to reduce the cost and the emissions. The comparison with other techniques demonstrates the superiority of the proposed approach and confirms its potential to solve the problem.

The criminal code has had a number of essential revisions during the past years, which has received distinct viewpoints concerning the improvement of punishments from the judiciary in criminal cases. The reasons of modifications can be explained mainly by the different penalty politics coming into prominence, occasionally having respect for different social approaches. It is periodically distinct which activities are indictable offences, which of the punishments serve the prevention of committing an act of crime the best in the fight against criminality. It is interesting to study how these sweeping changes can appear and effect in the daily legal activities. How far can the changes lobby the judges and prosecutors? Which punishment is ideal in the case - suiting to the aim of punishment – in the interest of the protection of society? As a result, analyzing judgments and interviewing some professional jurists (as far as I can) the different requirementson infliction of punishments do not appear immediately in practice and do not appear in the similar way concerning the functions of judges and prosecutors. It is not machines that pass judgement in a case, which could modify the expectation concerning the result.

Immunosuppressant drugs are the main treatment of lupus patient. The ACR and SLICC treatment guidelines are able to increase the quality of life, but the outcome is not satisfying since the off-label therapy of corticosteroids and cytotoxic drugs give a lot of side effects. Many breakthrough efforts still develop in order to find the safe and effective drugs for lupus, such as finding immunosuppressant drugs from natural resources. One of the potential resources is Kalanchoe pinnata (Lmk) Pers, which have immunosuppressant, anti-inflammatory, antinociceptive, and antioxidant effects. Thus, in the previous study, we found the effect of the aqueous extract of Kalanchoe pinnata (Lmk) Pers is active to repair the lupus manifestation in 2,6,10,14 tetramethylpentadecane (TMPD)-treated mice. Then, this research was focused on the in vivo immunosuppressant effect of a flavonoid-rich fraction of the extract which was consisted of the ethyl acetate (FE) and n-butanol (FB) fractions. The induction method and the extraction procedure were the same as the previous study and then the fractionation was performed by using liquid-liquid extraction. After 2-week treatment of both fractions, we obtained the differences in the total leukocytes, organ indexes, and also the spleen, kidney, and joint structure parameters. The total leukocyte of the FE group was 3,600Â±264 cells/mm3, which was lower than that in the FB group. The spleen and kidney indexes increased after the administration of FB fraction, while the FE fraction was not. At last, despite the histology observation of spleen resembled mild structural changes differences, the clear differences between both treatment groups occurred in the kidney and joint histology. The differences led to a conclusion that the FE fraction has the better immunosuppressant effect in TMPD-treated mice.

UBC Excavations of the Roman Villa at Gerace, Sicily: Results of the 2015 Season
Authors: Wilson R.J.A. , Ramsay Jennifer
Published: July 2017

A second season of excavation was conducted in 2015 at Gerace (Enna province, Sicily). In the small late Roman villa of ca. 370/375 ad identified by earlier work, the largest room, in the west wing, was found to have a floor of opus signinum, but the west corridor, in contrast to the mosaic-paved south corridor, had a floor of beaten earth throughout its life. The villa may never have been completely finished, even though occupation debris suggests it was frequented for much of the fifth century. Of the small freestanding bath-house at a higher level alongside it, only a single heated pool had survived later demolition. In its place two storerooms were inserted deep into the earth for efficient insulation. In the fire that destroyed the villa ca. 450/530 ad, a date supported by C14 analysis, the contents of these stores were carbonized: a huge cache of thousands of seeds, principally barley but also including wheat, grapes, and legumes, was uncovered there. The much larger, earlier store-building to the east, provisionally dated to ca. 325/350 and destroyed ca. 360, is now shown to have been a basilican structure. Three earlier phases of building have been detected below it; there is also a sherd of Attic Black Figure pottery, attesting activity at Gerace ca. 500 bc. A further 37 examples of stamps on roof tiles were discovered, including a single example from a hitherto unrecorded die; they were all part of the production, probably on site, of Philippianus, the likely owner of the Gerace estate in the late fourth century. After the fire of 450/530 ad, early Byzantine structures (seventh century?), much disturbed by the plough, occupied part of the site of the late Roman villa.

Sicily is a region located in the southern Italy. Its typical Mediterranean landscape is appreciated due to its high biodiversity. Specifically, hazelnut plantations have adapted in a definite area in Sicily (the Nebroidi park) due to specific morphological and climatic characteristics. However, many of these plantations are not used today due to adverse conditions, both to collect hazelnuts and to reach hazel groves. Though a geospatial analysis, the present paper aims to identify which hazelnut contexts can be actively used for agricultural, economic (e.g., introduction of a circular economy) and energetic purposes (to establish a potential agro-energetic district). The examination revealed the most suitable areas giving several criteria (e.g., slope, road system), ensuring an effective cultivation and consequent harvesting of hazelnuts and (ii) providing security for the operators since many of hazelnut plants are placed in very sloped contexts that are difficult to reach by traditional machines. In this sense, this paper also suggests optimal mechanization processes for harvesting hazelnuts in this part of Sicily.

Published: July 2017

This study is intended to prevent ochratoxin A (OTA) production by Aspergillus carbonarius S402 using essential oils (EOs) and total phenolic compounds extracted from plants and herbs. The EOs used in this study are the following: bay leaves, cumin, fenugreek, melissa, mint, and sage. As for the phenolic compounds, they were extracted from bay leaves, cumin, fenugreek, melissa, mint, sage, anise, chamomile, fennel, rosemary, and thyme. The experiments were conducted on Synthetic Grape Medium (SGM) medium at 28 °C for 4 days. OTA was extracted from the medium with methanol and quantified using HPLC (High Performance Liquid Chromatography). Results showed that EOs had a greater impact than the total phenolic extracts on the OTA production. Reduction levels ranged between 25% (sage) and 80% (melissa) for the EOs at 5 µL mL−1, and 13% (thyme) and 69% (mint) for the phenolic extracts. Although they did not affect the growth of A. carbonarius, total phenolic extracts and EOs were capable of partially reducing OTA production. Reduction levels depended on the nature of the plants and the concentration of the EOs. Reducing OTA with natural extracts could be a solution to prevent OTA production without altering the fungal growth, thus preserving the natural microbial balance.

Published: July 2017

Electrostatic force microscopy (EFM) is a useful technique when measuring the surface electric potential of a substrate regardless of its topography. Here, we have developed a frequency detection method for alternating current (AC) bias in EFM. Instead of an internal lock-in amplifier (LIA) for EFM that only detects ωe and 2ωe, we have used other LIAs that can amplify the amplitude of specific frequency by direct digital synthesizer (DDS), that finds the optimal frequency of surface charge images. In order to confirm the performance of the proposed methods, the electrical properties of lead zirconate titanate (PZT) and triglycine sulfate (TGS) samples were measured. In addition, we compared the performances of the frequency-detection method and the conventional EFM method. Ultimately, enhanced images could be achieved using the frequency-detection method. The optimal modulated frequency-shift for force–gradient measurements was found to be 2 kHz. Additionally, we have shown that it is possible to use a hard cantilever (K = 42 N/m, 330 kHz). Therefore, we expect that this technique can be applied to measure the electrical properties of bio-molecular films.
Vibration Control Design for a Plate Structure with Electrorheological ATVA Using Interval Type-2 Fuzzy System
Authors: Lin Chih-Jer , Lee Chun-Ying , Liu Ying
Published: July 2017

This study presents vibration control using actively tunable vibration absorbers (ATVA) to suppress vibration of a thin plate. The ATVA is made of a sandwich hollow structure embedded with electrorheological fluid (ERF). ERF is considered to be one of the most important smart fluids and it is suitable to be embedded in a smart structure due to its controllable rheological property. ERF’s apparent viscosity can be controlled in response to the electric field and the change is reversible in 10 microseconds. Therefore, the physical properties of the ERF-embedded smart structure, such as the stiffness and damping coefficient, can be changed in response to the applied electric field. A mathematical model is difficult to be obtained to describe the exact characteristics of the ERF embedded ATVA because of the nonlinearity of ERF’s viscosity. Therefore, a fuzzy modeling and experimental validations of ERF-based ATVA from stationary random vibrations of thin plates are presented in this study. Because Type-2 fuzzy sets generalize Type-1 fuzzy sets so that more modeling uncertainties can be handled, a semi-active vibration controller is proposed based on Type-2 fuzzy sets. To investigate the different performances by using different types of fuzzy controllers, the experimental measurements employing both type-1 fuzzy and interval type-2 fuzzy controllers are implemented by the Compact RIO embedded system. The fuzzy modeling framework and solution methods presented in this work can be used for design, performance analysis, and optimization of ATVA from varying harmonic vibration of thin plates.

The use of culture-independent approaches, such as metagenomics, provides complementary access to environmental microbial diversity. Mangrove environments represent a highly complex system with plenty of opportunities for finding singular functions. In this study we performed a functional screening of fosmid libraries obtained from an oil contaminated mangrove site, with the purpose of identifying clones expressing hydrolytic activities. A novel gene coding for a β-N-acetylhexosaminidase with 355 amino acids and 43KDa was retrieved and characterized. The translated sequence showed only 38% similarity to a β-N-acetylhexosaminidase gene in the genome of Veillonella sp. CAG:933, suggesting that it might constitute a novel enzyme. The enzyme was expressed, purified, and characterized for its enzymatic activity on carboxymethyl cellulose, p-Nitrophenyl-2acetamide-2deoxy-β-d-glucopyranoside, p-Nitrophenyl-2acetamide-2deoxy-β-d-galactopyranoside, and 4-Nitrophenyl β-d-glucopyranoside, presenting β-N-acetylglucosaminidase, β-glucosidase, and β-1,4-endoglucanase activities. The enzyme showed optimum activity at 30 °C and pH 5.5. The characterization of the putative novel β-N-acetylglucosaminidase enzyme reflects similarities to characteristics of the environment explored, which differs from milder conditions environments. This work exemplifies the application of cultivation-independent molecular techniques to the mangrove microbiome for obtaining a novel biotechnological product.
