The role of prostaglandins and polymorphisms of A2 phospholipase genes in the occurrence of early uterine contractions during pregnancy
Authors: Borowiec Blanka , Hadada Tomasz , Kosińska Magdalena
Published: January 2019

This study focused on the role of polymorphisms in prostaglandin expression regulating genes in the occurrence of early uterine contractions during pregnancy. The analyzed genes were: PLA2G4C, encoding calcium independent phospholipase A2, and PLA2G4C, encoding IVD phospholipase A2. It was examined if known reference polymorphisms in these genes (rs1366442, [A/C/T] for PLA2G4C; and rs4924618, [A/T] for PLA2G4D), have any influence on preterm birth. Additionally, other biological, genetic and socio-economic factors were taken into account and analyzed, based on their role in induction of early resolve of pregnancy in the study group. Blood samples were taken from 20 patients. 15 of them gave birth preterm, 5 gave birth at the predicted date of pregnancy resolve. DNA was isolated from the samples, and subjected to PCR, with obtained amplified samples separated using electrophoresis on 1,5% agarose gel. Resulting material was subjected to high-throughput sequencing. Statistical analysis was performed using Statistica 13 software. Analyses have shown that the discussed biological, genetic and societal-economic factors have statistically significant influence on preterm birth. Sequencing results presented the suspected presence of the analyzed SNPs in most women from the studied groups, while not showing their presence in any of the controls. The biological, genetic, and socio-economic factors analyzed have a significant influence on pre-term birth. Presence of SNPs in PLA2G4C and PLA2G4D genes may increase the risk of early resolve of pregnancy. However, as the control and study groups were relatively small, it is suggested to repeat the studies on bigger samples to validate the results.

Authors: Kubavat Kinjal K. , Samova Sanman , Doctor Hetal , Sindhav Gaurang M. , Verma Ramtej J.
Published: January 2019

One of the natural antioxidant flavonols -Quercetin is found in various food products and plants. Its anticancer properties have been proved by in vivo and in vitro experiments; it shows an attempt to examine toxic effects of Bisphenol A in the liver of mice and its alleviation by quercetin. For this inbred Swiss strain male albino mice were orally administered with quercetin (30, 60 and 90 mg/kg body weight/day) along with BPA (240 mg/kg body weight/day) for 45 days. On the completion of the treatment period, animals were sacrificed; organs were isolated and used for biochemical analysis. All these effects were dose-dependent. Co-treatment with quercetin (30, 60 and 90 mg/kg body weight) and BPA (240 mg/kg body weight) alleviates the changes in body weight, absolute and relative organ weights of mice. Biochemical analysis revealed significant (p < 0.05) and dose-dependent reduction in enzymatic antioxidants such as superoxide dismutase, Catalase and glutathione peroxidase and non-enzymatic antioxidants such as Glutathione and Total ascorbic acid content were also observed in Bisphenol A -treated groups as compared to control. The present results revealed that graded doses of BPA caused oxidative damage in the liver of mice, which is mitigated by quercetin.

Authors: Bharamagoudar Ravi C. , Patil Anil S. , Mathad Shridhar N. , Kumbar Vijay M. , Kankanawadi Laxmi B.
Published: January 2019

The main objective of the manuscript is the structural analysis, magnetic investigation and antimicrobial activity of Mn1−xZnxFe2O4 with stoichiometry (x = 0, 0.25, 0.5, 0.75, and 1.0). The Mn-Zn nanoferrites were synthesized by self propagating high-temperature synthesis using a mixture of fuels. The synthesized Mn-Zn nanoferrites were characterized by X-ray diffraction (XRD) that confirms cubic crystal structure with lattice constant in the range 8.372-8.432Ao. It is observed that saturation magnetization (Ms), remanence magnetization (Mr) and magneton number (Mr/Ms) decreased gradually with the increasing of Zn2+ concentration. The decrease in the saturation magnetization may be explained as, the Zn2+ concentration increases, the relative number of ferric ions on the A sites diminishes and this reduces the A–B interaction. Further, the synthesized Mn-Zn nanoferrites were tested for antibacterial activities against two-gram positive strains (Staphylococcus aureus ATCC No–12598, Lactobacillus amylovorus ATCC No– 12598), gram-negative strains E.coli ATCC No – 25922, Pseudomonas- ATCC No- 25619) and one fungal strain (C.albicans -ATCC No – 2091).

Two-Parametric Analysis of Anti-Plane Shear Deformation of a Coated Elastic Half-Space
Authors: Sultanova Leyla
Published: January 2019

The anti-plane shear deformation problem of a half-space coated by a soft or a stiff thin layer is considered. The two-term asymptotic analysis is developed motivated by the scaling for the displacement and stress components obtained from the exact solution of a model problem for a shear harmonic load. It is shown that for a rather high contrast in stiffness of the layer and the half-space Winkler-type behaviour appears for a relatively soft coating, while for a relatively stiff one, the equations of plate shear are valid. For low contrast, an alternative approximation is suggested based on the reduced continuity conditions and the fact that the applied load may be transmitted to the interface. In case of a stiff layer, a simpler problem for a homogeneous half-space with effective boundary condition is also formulated, modelling the effect of the coating, while for a relatively soft layer a uniformly valid approximate formula is introduced.
Optimization of Enset Fermentation in the Production of Kocho Using Response Surface Methodology
Authors: Weldemichael Helen , Admassu Shimelis , Alemu Melaku
Published: January 2019

Response surface methodology (RSM) was used for optimization of enset fermentation process. Two numerical (time and amount of starter culture) and one categorical variable (types of starter strain) was used for evaluation of sensory quality of kocho. The physicochemical properties, proximate composition and color of kocho product were also analyzed. It was found that the coefficient of determination (R2) of the response variables were greater than 80% described that high percentage of the variability was defined by the model. These findings revealed that fermentation time, amount of starter culture and types of starter strain affected the sensory attributes of kocho. The preferred sensory quality of kocho was produced using 2% L. plantarum as starter strain at 6 days of fermentation time.

Authors: Płuciennik-Koropczuk Ewelina , Kumanowska Patrycja
Published: January 2019

The article presents the results of research on changes in selected water parameters during distribution in the water supply network of the city of 22 thousand inhabitants. Water parameters were controlled at 8 points in the network, distant from Water Treatment Plant from 0.4 to 3.1 km. The location of control points was selected in order to assess the water quality depending on the pipe material and at unfavourable points - at the ends of the network. It was shown that as a result of secondary water contamination an increase in turbidity, colour and total iron occurred. The distance from the Water Treatment Plant and the type of material of the network or connection, affect the quality of the water. It was confirmed that at the ends of the network the water parameters were increased and exceeded the admissible values.

Authors: Khene Ahmed , Mesbah Habib Abdelhak , Chikh Nasr-Eddine
Published: January 2019

In this study, we have chosen to use a new technique of reinforcement with composite materials, namely the near surface mounted technique (NSM). The NSM technique consists in inserting strips of carbon fiber reinforced polymer (CFRP) laminate into slits made beforehand at the level of the concrete coating of the elements to be reinforced. A numerical investigation was conducted on rectangular reinforced concrete beams reinforced with NSM-CFRP using the ATENA finite element code. A parametric study was also carried out in this research. The numerical results were compared with the experimental results of the beams tested by other researchers with the same reinforcement configurations. Overall, numerical behavior laws are rather well-suited to those obtained experimentally and the parametric study has also yielded interesting results.

Authors: Ochałek Agnieszka , Niewiem Witold , Puniach Edyta , Ćwiąkała Paweł
Published: January 2019

In this paper, authors present results of accuracy verification of the Trimble RTX technology. The GNSS receiver Spectra Precision SP60 was used in Cyprus (Kato Paphos Archaeological Park). To evaluate the accuracy of the receiver, two measuring test networks (consisting of 30 and 55 control points) were established. All points were determined in four measuring cycles. Additionally, in order to make more advanced analysis of the data, the bases were also measured by using another GNSS receiver - Geomax-Zenith 25. The point positions, in this case, were conducted in the local coordinate system of Kato Paphos Archaeological Park by using RTK positioning technology. To make a comparison, it was necessary to transform the coordinates based on different groups of fitting points. Analysis allowed to conclude that the Spectra Precision SP60 receiver and the RTX Trimble technology guarantee repeatable results (on the level of 4 cm) of point positioning measurements.

The article describes the results of tests carried out to determine the measurable effect of vibrations on the accuracy of measurements with an automatic precise leveller. It contains specification of the research station created to examine the case and description of factors affecting the measurement results. The multi-frequency vibrations were forced on a leveller during measurements and calculated mean errors for each frequency analysed. The range of frequencies for which the measurement was possible was estimated. The obtained results can be helpful in the engineering measurements designing, especially in industrial areas, where vibrations are an inseparable element of the environment.
Magnetic and Very Low Frequency Electromagnetic (VLF-EM) investigations for gold exploration around Ihale in Bunnu-Kabba Area of Kogi, north-central Nigeria
Authors: Osinowo Olawale Olakunle , Falufosi Michael Oluseyi
Published: January 2019

This study integrates ground magnetic and Very Low Frequency Electromagnetic (VLF-EM) methods of geophysical investigation to probe the subsurface in terms of rock magnetic susceptibility and ground conductivity for the purpose of identifying mineralized pegmatite veins that could serve as host for gold and associated metallic deposits. Twenty five (25) carefully planned ground magnetic and VLF-EM profiles, each, were occupied east and west of a reference profile which was purposively established on an identified mineralized pegmatite vein around Ihale in Bunnu-Kabba area of Kogi, north-central Nigeria. The acquired ground magnetic data were filtered and Reduced To Pole at Low Latitude (RTPLL) to remove regional field effect, cultural noise as well as focus the peaks of magnetic anomalies over corresponding sources. The measured raw real and raw imaginary components of the EM fields were subjected to Fraser and Karous Hjelt filtering to remove harmonic noise, focus and make anomaly amplitudes relate directly to the causative conductor as well as generate current density employed to characterise the subsurface. Seven (7) zones of relatively high VLF-EM derived current density with matching high residual positive magnetic anomalies present closely correlate-able signatures with subsurface response obtained around the reference profile established where local mining activities indicate evidence of gold and associated metallic mineralization of the pegmatite vein. The delineated zones constitute targets for gold and associated base metal prospects which could be further developed for economic benefit of the community.
Moral emotions
Authors: Spielthenner Georg
Published: January 2019

Moral emotions have been badly neglected by philosophical ethics. In my view to the detriment of this discipline because they are not only important for the moral evaluation of persons but also for value theory and thus also for a theory of morally right actions. This paper outlines my account of moral emotions. Emotions such as regret or shame are sometimes but not always moral emotions. I will determine when they (and other emotions) are moral emotions. In (I) I will deal with the views of some other authors and in (II) and (III) I will explain my own account.
A Simple Realist Account of the Normativity of Concepts
Authors: Lalumera Elisabetta
Published: January 2019

I argue that a concept is applied correctly when it is applied to the kind of things it is the concept of. Correctness as successful kind-tracking is fulfilling an externally and naturalistically individuated standard. And the normative aspect of concept-application so characterized depends on the relational (non-individualistic) feature of conceptual content. I defend this view against two objections. The first is that norms should provide justifications for action, and the second involves a version of the thesis of indeterminacy of reference.
A defence of Fregean propositions
Authors: Vignolo Massimiliano
Published: January 2019

Stephen Schiffer 2003 presents six arguments against the Fregean model of propositions, according to which propositions are (a) the referents of that-clauses and (b) structured entities made out of concepts. Schiffer advances an alternative view: propositions are unstructured pleonastic entities. My purpose is to argue in favour of the main tenets of the Fregean model by countering each of Schiffer’s arguments and sketching the guidelines for a theory of concepts as basic components of propositions.
Relevant Alternatives Contextualism and Ordinary Contingent Knowledge
Authors: Lihoreau Franck
Published: January 2019

According to David Lewis’ contextualist analysis of knowledge, there can be contexts in which a subject counts as knowing a proposition just because every possibility that this proposition might be false is irrelevant in those contexts. In this paper I argue that, in some cases at least, Lewis’ analysis results in granting people non-evidentially based knowledge of ordinary contingent truths which, intuitively, cannot be known but on the basis of appropriate evidence.
Dubbings-in-Trouble
Authors: Galanakis Dimitris A.
Published: January 2019

Pelczar and Rainsbury advance a theory of proper names which purports, inter alia, to implement Kripke’s causal theory of name reference in order to explain reference change. The key tool for accomplishing this is the notion of a dubbing-in-force. In this paper I aim to show that this special appeal to dubbings does not sustain any real advance over Kripke’s account at least with respect to the problem of inadvertent referential shift. I argue that this theory has not offered any theory of reference transmission, which I take as a precondition for explaining the problem of reference change, and that the notion of a dubbing-in-force is unnecessary for name reference.

The weak collective agential autonomy thesis
Authors: Botting David
Published: January 2019

Can a collective be an agent in its own right? Can it be the bearer of moral and other properties that we have traditionally reserved for individual agents? The answer, as one might expect, is ‘In some ways yes, in other ways no.’ The way in which the answer is ‘Yes’ has been described recently by Copp; I intend to discuss his position and defend it against objections. This describes a fairly weak form of autonomy that I will claim does not require the abandonment of methodological individualism or our commonplace intuitions about individual responsibility. I will also discuss, and reject, a stronger conception of autonomy suggested especially by the work of Pettit that would result in methodological individualism.
Does Ontology Matter?
Authors: Graham Andrew
Published: January 2019

In this paper, I argue that various disputes in ontology have important ramifications and so are worth taking seriously. I employ a criterion according to which whether a dispute matters depends on how integrated it is with the rest of our theoretical projects. Disputes that arise from previous tensions in our theorizing and have additional implications for other issues matter, while insular disputes do not. I apply this criterion in arguing that certain ontological disputes matter; specifically, the disputes over concrete possible worlds and coincident material objects. Finally, I consider how one could show that some ontological disputes do not matter, using a Platonism/nominalism dispute as an example.

The Unificatory Power of Scientific Realism
Authors: Park Seungbae
Published: January 2019

The no-miracles argument (Putnam 1975) holds that science is successful because successful theories are (approximately) true. Frost-Arnold (2010) objects that this argument is unacceptable because it generates neither new predictions nor unifications. It is similar to the unacceptable explanation that opium puts people to sleep because it has a dormative virtue. I reply that on close examination, realism explains not only why some theories are successful but also why successful theories exist in current science. Therefore, it unifies the disparate phenomena.

Experimental identification of essential features of micro strip drawing with double deflection
Authors: Rathmann Lewin , Vollertsen Frank
Published: January 2019

In sheet metal forming contact between blank and die edge is reduced to local contact zones. For micro range, they can easily be found during
a simulation, but an experimental evidence is difficult.
Therefore, an optical projection of strip drawing with double deflection is presented and it is demonstrated that the contact zones can be identified using this method. These results are
compared to those from simulation and it is shown that they reflect the simulative results. The results are presented on the basis of using a die with a die radius of r = 0.6 mm. The height of the gap between die edge and blank at the moment of their maximum distance is determined in the experiment to d = 18 ± 9 μm while it is d = 2 μm in the simulation.
Weld Cladding of s355 Steel with Rectangular Electrode Covered Rutile 2000 s Coating
Authors: Bjelajac Edvard , Vuherer Tomaž , Lojen Gorazd
Published: January 2019

Weld cladding or weld overlay is a frequently used method for repair welding of damaged surfaces and for production of different surface coatings. The conventional coated electrodes have a circular cross-section. In order to increase the productivity and to decrease dilution and the depth of the heat affected zone (HAZ), the geometry of the electrode core was modified. Experimental weld cladding was carried out with rutile coated electrodes of rectangular cross-sections of
12.56×1 mm2, and for reference, also with a conventional φ 4 mm electrode Rutilen 2000 S. The coating of rectangular electrodes was identical and the core material almost identical to the materials of the standard electrode. The base material was the structural steel 355JR.
The goal of investigation was to determine the welding parameters for the rectangular electrodes and to compare geometries and mechanical properties of the welds. Hardness and the dimensions
of weld metal and HAZ were measured. Results with the 6.28×2 mm
2 and 6.28×2 mm electrode were similar to the results with the standard electrode. However, with the 12.56×1 mm2 rectangular electrode, significantly lower currents were sufficient to obtain a good quality of the deposition layer. Due to possibility to weld with currents as low as 80-100 A, shallower and smaller HAZs and less dilution can be achieved with the rectangular 12.56×1 mm2 electrode than with standard cylindrical φ 4 mm electrode.

Published: January 2019

Efficiency and lifetime of manufacturing tools and mechanica
l components may be successfully improved by application of thin ceramic coatings. When it comes to tools for machining of hard
materials such as machining of hardened steel, TiAlN is one of the most usually applied coatings. This material is of high hardness, high oxidation resistance and high temperature stability. In this research, surface morphology, mechanical and tribological properties of TiAlN coatings prepared in industrial deposition unit were studied. Three different coatings were prepared by selecting different rotational types in a magnetron sputtering deposition chamber. Surface morphology was
characterized by stylus profilometry and atomic force microscopy, mechanical properties by nanoindentation technique and Rockwell indentation test, while pin-on-plate test was used to study tribological behavior. It was found that coatings prepared by higher number of rotations are smoother, harder, and more resistant to cracking
and wear. These differences are attributed to differences in coating microstructure which refines with increased number of rotations.

Hal ini didasari harga komoditas pangan impor yang relatif lebih rendah dibandingkan dengan harga komoditas pangan di pasar domestik, dengan kualitas produk yang lebih terjamin. Para pelaku rantai pasok dalam hal ini perlu proaktif membina kerjasama untuk mewujudkan pemasaran komoditas pangan yang efisien mulai dari petani sampai ke industri pengolahan.Â  Wujud kerjasama yang saling menguntungkan adalah suatu sistem koordinasi diantara pelaku rantai pasok. Sistem koordinasi dalam rantai pasok komoditas pangan belum diketahui tingkatannya, oleh karena itu perlu diteliti tingkat koordinasi dalam rantai pasok komoditas komoditas pangan baik lokal maupun impor. Penelitian ini mengangkat permasalahan utama tentang tingkat koordinasi, yaitu bagaimanakah tingkat koordinasi dalam rantai pasok komoditas pangan lokal dan impor. Koordinasi dalam rantai pasok komoditas pangan lokal umumnya termasuk kategori tidak terkoordinasi dan dalam rantai pasok komoditas pangan impor pada umumnya terkoordinasi. Untuk menjawab permasalahan ditempuh tiga tahap analisis, yaitu analisis faktor, analisis cluster dan analisis diskriminan. Hasil penelitian menunjukkan bahwa terdapat perbedaan yang signifikan antara tingkat koordinasi dalam rantai pasok komoditas pangan yang terkoordinasi dengan rantai pasok komoditas pangan yang tidak terkoordinasi, dimana rata-rata skor diskriminan rantai pasok komoditas pangan terkoordinasi lebih besar dari rantai pasok komoditas pangan tidak terkoordinasi. Disarankan kepada pemerintah untuk melakukan pembinaan sistem koordinasi, sehingga rantai pasok menjadi suatu kesatuan yang para pelakunya saling tergantung dan saling menguntungkan satu sama lain. Pada akhirnya setiap pelaku rantai pasok diharapkan akan memiliki rasa tanggung jawab terhadap peningkatan kinerja perorangan dan kelompok.

Circula trifenestrata is a kind of golden silkworms that are native wild habitat tropical areas like Indonesia. This gold silkworm living on host plants such as cashew nut, avocado, cocoa, soursop, mango, quinine and kedondong. Sidomulyo is largest coffee producer in Jember, and avocado crops are very abundant population because these plants shade the coffee plants. People assume that this type of worm that attacked the plant avocado is a kind of pest caterpillars can spend the leaves quickly and reduce the productivity of harvesting the fruit so that the caterpillars are often exterminated by farmers. The purpose of this study was to determine the outlook and development strategy pests into gold silk as potential Kab.Jember Sidomulyo village. Respondents who used an avocado farmer in the village of Sidomulyo, using analysis of FFA (Force Field Analysis) that identify factors driving and inhibiting factors in an activity will be achieved. The results showed the total value of the park on the driving factor is equal to 1.59 (D2 silkworm cocoon abundance of gold in avocados) while the number of inhibiting factors in the amount of 1.40 (H4 has been no development of silkworm farming gold in Kab.Jember). It shows that the value of the driving factors is greater than the value of the park in an inhibiting factor. Therefore, the cultivation of silkworms in Jember has the advantage to improve the prospects and potential development of silkworm gold C.trifenestrata in Jember.Â Keywords: Circula trifenestrata, silkworms gold, avocado, potential village

Teknologi surface textured yang merupakan salah satu teknik untuk pengembangan penyerap gelombang elektromagnetik telah mengalami perkembangan yang cukup pesat dalam dekade terakhir ini. Pada aplikasi penyerap, teknologi ini mampu mengurangi ketebalan material sehingga memungkinkan realisasi material yang lebih tipis. Secara prinsip, teknik ini menggunakan lapisan AMC (artificial magnetic conductor) yang mempunyai high impedance surface. Untuk mendapatkan tingkat penyerapan yang tinggi yang dapat bekerja pada frekuensi penyerapan yang diinginkan, metal patch dari penyerap tersebut dibuat dengan bentuk tertentu. Pada penelitian ini, dilakukan investigasi bentuk patch segi enam sama sisi yang dicetak di atas substrat dielektrik FR4 Epoxy dengan ketebalan 3,2 mm. Ukuran substrat dielektrik sel satuan yang didapatkan untuk bentuk segi enam 30 mm � 26,5 mm, sedangkan lebar sisi patch yang diperoleh 14 mm. Selanjutnya untuk mendapatkan tingkat penyerapan yang baik dilakukan penambahan elemen resistif pada patch. Nilai resistor yang perlu ditambahkan pada patch saat perancangan adalah 514 : dengan tingkat penyerapan pada frekuensi kerjanya sebesar 47 dB. Pengukuran telah dilakukan dengan menggunakan alat bantu PPW simulator. Kemudian dilakukan proses pemisahan karakteristik penyerap dari alat pengukurannya. Penambahan resistor sebesar 487 : memberikan pengaruh karakteristik penyerapan hingga 34 dB lebih baik sekitar 7 dB pada frekuensi resonansi 2,78 GHz bila dibandingkan dengan pengukuran tanpa R.

Dalam usaha untuk melindungi hak cipta dan keaslian dari suatu objek tiga dimensi, diperlukan sebuah algoritma untuk menyisipkan informasi rahasia yang tidak nampak oleh indera penglihatan manusia namun dapat dideteksi dengan menggunakan suatu media, misalnya komputer. Oleh karena itu watermark menjadi sebuah solusi terbaik untuk permasalahan tersebut. Metode yang digunakan untuk menanamkan watermark ke dalam objek 3 dimensi adalah metode connected vertices clustering and topology star, dimana sebuah objek 3 dimensi dibagi-bagi menjadi beberapa topologi star berdasarkan vertex vertex-nya yang saling terhubung. Dari topologi star ini dipilih edge-edge untuk disisipi informasi watermark dan dengan menggunakan sebuah PN sequensial dipilih edge yang vertex-nya disisipi oleh watermark. Hasil yang diperoleh dari simulasi sitem watermarking ini adalah didapat sebuah skema penanaman watermark dengan kualitas imperceptibility yang baik karena memiliki nilai BER dan VER yang mendekati 0 serta nilai SNR yang besar. Selain itu watermark dapat diekstrak dengan sangat baik setelah diberi serangan rotasi, scaling, translasi, serta kombinasi serangan scaling dan translasi dengan nilai BER 0. Skema ini tidak robust terhadap serangan cropping.Kata Kunci: object 3D, watermarking, star topology, connected vertices clustering
