Impact of different pineapple mealybug densities in a peanut crop
Authors: Domingues da Silva Carlos Alberto , Vasconcelos Eduardo Domingos , De Almeida Raul Porfirio 
Published: November 2018

The pineapple mealybug Dysmicoccus brevipes (Hemiptera: Pseudococcidae) is a cosmopolitan and polyphagous species that causes severe damage to peanut crops in many countries around the world. This work was conducted in Campina Grande, Paraíba Sate, Brazil, aiming to assess losses in productivity caused by D. brevipes in a peanut crop. A completely randomized design with five treatments and four replicates was used. Treatments consisted of five mealybug population densities (nymphs and adults) on peanut roots and pods, described as follows: T1 = 0 mealybugs per plant; T2 = 1 to 20 mealybugs per plant; T3 = 21 to 40 mealybugs per plant; T4 = 41 to 80 mealybugs per plant and T5 = more than 80 mealybugs per plant. Roots and pods infested with the pest were observed on 84 % of the peanut plants sampled, ranging from zero to 147.1 individuals per plant. The higher the number of mealybugs per plant, the lower the weight of pod. The mean pod productivities of BR1 peanut cultivars, with the highest and lowest densities of mealybugs per plant were 1,695 and 3,290 kg per ha, respectively. Fields heavily infested with D. brevipes risk significant losses due to the enormous capacity of this organism for causing damage.

Статтю присвячено розгляду психологічних аспектів оцінювання персона­лу в системі державної служби. Виокремлено основні причини неефективності такого оцінювання: формальність і суб’єктивність, відсутність зворотного зв’язку, неузгодженість самооцінки працівника з оцінками експертів, неаде­кватне сприйняття державними службовцями сутності оцінювання. Наголо­шено на специфіці професійної діяльності в системі державного управління: публічності, соціальній орієнтованості, спрямованості на задоволення потреб громадян. Зазначено, що «оцінка» є основним елементом поняття ефектив­ність державного управління, оскільки відображає рівень розвитку суспільства і рівень функціонування державної служби. Акцентовано увагу на соціально-психологічній сутності оцінювання, недостатній розробленості й визначеності вимог (соціальних норм) до особистості та діяльності державних службовців, необхідності розроблення адекватних методів та процедур оцінки.Узагальнено результати емпіричного дослідження, у ході якого виявлено професійно важливі якості державних службовців, виокремлено й обґрунтовано критерії та показники оцінки рівня їхнього професіоналізму, здійснено порів­няння ефективності різних діагностичних методик оцінювання персоналу в системі державної служби. За допомогою методів прямої оцінки й вимушеного вибору визначено рівень необхідності та рівень сформованості в державних службовців професійно важливих якостей, які відображені в оцінному листі оцінки персоналу в системі державної служби. Виокремлено крите­рії аналізу професійної ефективності державних службовців (професіоналізм; трудова та виконавча дисципліна; особистісні (професійно важливі) якості; взаємодія з керівництвом, колегами, клієнтами; професійна мотивація; потреба у навчанні; обсяг роботи, що виконується), запропоновано якісні та кількісні показники для аналізу кожного з критеріїв. Здійснено процедуру експертної оцінки важливості виокремлених критеріїв та їхньої відповідності посадовим обов’язкам праців­ника.

Frequency Analysis of a Potential SPB Star η Tau
Authors: ÖZUYAR Doğuş 
Published: November 2018

In this study, five years of photometric data of η Tau
obtained from the STEREO satellite
between 2007 and 2011 are presented. The high-precision data are compared with
the results derived from the spectroscopic findings to gain a better
understanding of the Be phenomenon in the star. The spectroscopic data cover
the same time interval as the photometric observations. η Tau displays a double
peaked Hα emission profile in its spectra. In order to analyze this profile,
the Hα emission lines are examined by measuring their equivalent widths and
line intensities. As a result of the photometric and spectroscopic analyses, it
is revealed that the frequency distribution and amplitude intensities of the
star are different from those of a typical Be star. Based on its physical
parameters such as temperature and luminosity values, it may be conclude that
the star is a Slowly Pulsating B type emission star. On the other hand, the
equivalent width values of the emission lines appear to be related to the
oscillation frequencies and their amplitudes. This indicates that the
photometric variations may be related to the environmental disc structure.Doğuş ÖZUYAR, dozuyar@ankara.edu.tr, ORCID: https://orcid.org/ 0000-0001-8544-0950

Published: November 2018

Teknologi modern pada bahan konstruksi pesawat terbang dituntut untuk dapat menemukan bahan-bahan yang ringan namun memiliki daya tahan (kekuatan) yang besar. Bahan dengan karakter seperti ini sangat banyak gunanya, terutama dimanfaatkan sebagai bahan utama untuk badan pesawat terbang. Saat ini, pesawat-pesawat terbaru menggunakan bahan komposit sebagai komponen utama badan pesawat. Penelitian pembuatan komposit resin polyester berpenguat serat sabut kelapa bertujuan untuk mengetahui pengaruh penambahan serat sabut kelapa terhadap nilai energi impact yang diserap rata-rata dari setiap variasi fraksi berat serat 0%, 1%, 2%, 3%, 4% dengan matrik resin polyester 200 ml. Dari hasil pengujian impact metode charphy dengan standard ASTM E-23 didapatkan nilai energi yang diserap rata-rata tertinggi terjadi pada penambahan fraksi berat serat 4% sebesar 338,6 Joule. Hal ini menunjukkan bahwa semakin banyak penambahan fraksi berat serat sabut kelapa, maka energi yang diserap pada pengujian impact akan semakin besar karena ikatan antara matriks dan serat sabut kelapa dapat menjadikan material komposit menjadi tahan akan benturan jika dikenai beban. Dan untuk hasil mode patahan pada fraksi berat serat 0% yang terlihat adalah mode patahan matrix rich. Sedangkan untuk fraksi berat serat 1-4% mode patahan yang terlihat adalah pullout dan overload.Kata Kunci: Komposit,Mode patahan, Resin polyester,Serat sabut kelapa,Uji impact

Published: November 2018

AbstractDifferent generations of cationic hyperbranched quaternary ammonium polyamidoamine dendrimers (PAMAM) with methyl ester end group (G-0.5, G 0.5, G1.5 and G 2.5) were synthesized. Preparation of these dendrimers was carried out via alternative steps of an aza Michael addition reaction (of piperazine as core center molecule) and amidation reaction by ethylene diamine. Each aza Michael addition step was followed by a quaternization step using alkyl bromide with different chain length (4, 8 or 12) carbon atoms. The chemical structures of the prepared dendrimers were confirmed using FTIR, 1H-NMR spectra and elemental analysis for two generations as representative compounds. Also their surface activity has been studied and their surface parameters including surface and interfacial tension, emulsification power, critical micelle concentration, effectiveness, efficiency, maximum surface excess and minimum surface area were determined. The prepared quaternized dendrimers were tested as antimicrobial agents against different strains of bacteria, yeast and fungi. The results showed a significant antimicrobial efficacy of the synthesized surfactants.

Published: November 2018

AbstractA sophorolipid (glycolipid biosurfactant from Starmerella bombicola) has valuable properties in addition to surface active attributes. This sophorolipid was produced as a secondary metabolite by submerged fermentation using hydrophobic (sunflower oil) and hydrophilic (glucose) substrate. The present work investigates the effect of inoculum age, oil feed and incubation period to increase sophorolipid yield. The highest yield of sophorolipid by sunflower oil was accomplished with an inoculum age of 60 h. Maximum substrate consumption and sophorolipid yield were found near about 200 h. At optimized fermentation conditions, 19.2 g/L yield of sophorolipid was achieved. The lactonic sophorolipid which is the major component of crude sophorolipid was separated and purified by adsorption chromatography. Normal phase and reverse phase resin were compared for adsorptive purification among which reverse phase resin provides better purification with 69 % recovery. Further surfactant and antimicrobial properties of crude sophorolipid were studied.
Influence of Stitching Parameters on the Joint Strength of Welded-Stitched Composites

Published: November 2018

Abstract
Regarding the necessity of lightweight construction, performance and design, composites are well established. At this moment, the joining of these composites still is often a major challenge. While suitable technologies like welding, sticking or riveting do exist, there are several drawbacks of these technologies such as damaging the fiber structure and low bonding strength. The combination of welding and sewing is a novel approach to improve the bonding of glass fibre-reinforced polypropylene and the influence of the processing parameters is not yet well understood. This study aims at analyzing the influence of parameters such as operating temperature, overlap length, needle temperature and thread material on the tensile strength of thermoplastic composites joined in the previously described hybrid approach. Furthermore, the interaction between thread and composite material is investigated by a microscopical analysis. The joint strength has been found to depend on the overlap length of the joint and the results suggest a contribution of the seam to the joint strength, especially for lower overlap lengths. Influences of the processing temperature, the thread material and needle temperature are also present, however, due to the complex interaction, no systematic conclusions could be drawn for these yet. The optical analysis confirms the findings of thermoset composites stitched before impregnation, where additional seams cause dislocations and local agglomeration of fibers. Additional investigations are necessary to determine the effect of the stitching on the joint and to further the understanding of the interaction between composite and thread material.
Extensional Rheology and Processing of Polymeric Materials
Authors: Münstedt H. 
Published: November 2018

Abstract
Many processing operations of polymeric materials are dominated by extensional flow. In this paper the question is addressed in which way rheological data obtained from elongational laboratory experiments can be used to describe the material behavior in various processes. Particularly discussed is the uniformity of geometrical features of items with respect to the strain hardening of the polymeric materials, because uniformity is important for many end-use properties. Convincing correlations with extensional rheology could not be established for thermoforming experiments on polypropylene. However, for blown and drawn films it was found that the uniformity of thickness improved, if strain hardening was introduced. The bubble stability could be related to the melt strength of the sample. Furthermore, the influences of elasticity and strain hardening on the neck-in during drawing of films were elucidated. Moreover, it was shown in which way extensional rheology can be used to assess foaming.

Abstract
Thermoplastic injection molding is applied in a wide variety of products. It is known that volatile components generated when resin melts cause structural defects during the thermoplastic injection process. Not only that, the pre-injection preparation work including drying the material and maintaining the metal mold, have become standard procedures to prevent these defects, but these procedures deteriorate productivity. Vent-type injection molding involves the use of cylinders featuring a vent hole at the center of the plasticizing cylinder. Although it is a conventional molding method, there are many issues including resin leakage from a vent hole and difficulty of material replacements. These issues prevented it from widespread application. Moreover, the vent-type plasticization process has not been examined theoretically or systematically. In order to maximize and generalize functions of vent-type molding, it is necessary to clarify the flow behavior of resin in the vent cylinder. In this study, we verified the flow behavior of resin in the vent-type plasticization cylinder through experimentation and simulation. In the simulation, using the flow analysis method, the filling rate inside the screw was determined by the pressure distribution inside the screw. In the experiments, the molding condition that causes venting up was verified by changing the screw rotation rates and the supply amount of the resin, for determining the filling rate of resin inside the screw. The filling rates obtained through the simulation and the experiment are almost the same. The result suggests that this simulation is very effective for predicting the filling rate.
Crystallization Kinetics and Multiple Melting Behavior of Biodegradable Poly(3-hydroxybutyrate-co-4-hydroxybutyrate)
Authors: Tong B.-B. , Ding Y.-H. 
Published: November 2018

Abstract
The crystallization and melting behavior of biodegradable poly(3-hydroxybutyrate-co-4-hydroxybutyrate) [P(3HB-co-4HB)] with 11 % 4HB content was investigated by differential scanning calorimetry (DSC), small and wide angle X-ray scattering (SAXS and WAXS). The Avrami analysis was performed to obtain the kinetic parameters of crystallization. The results showed that the Avrami equation was suitable for describing the isothermal and nonisothermal crystallization processes of P(3HB-co-4HB). Based on the values of the equilibrium melting temperature and the half-time of crystallization, its nucleation constant of crystal growth kinetics was obtained by using the Lauritzen-Hoffman model, which was found to be 1.92 × 105 K2, lower than that for pure PHB. During the subsequent heating process, quite different multiple melting behaviors were observed for P(3HB-co-4HB) crystallized isothermally or nonisothermally. The origins of the multiple melting behaviors were discussed based on either the presence of dual lamellar thicknesses or the melt-recrystallization mechanism. In general, the crystallization and melting behaviors were elucidated by this work.

The study reveales psycholinguistic peculiarities of understanding of indirect meaning of the proverbs and idioms of Ukrainian speaking pre-school children. The experiment took place on the basis of pre-school education establishments of Ukraine. The participation number is 378 children at the age of 5 years (till 5.5 years). The used psycholinguistic methods are: а) «evaluation of understanding of the indirect metaphors meaning» (Vygotskyi, 2000); b) «evaluation of proverbs understanding» (Luriia, 1998). The other used psycholinguistic methods are: а) «Proverbs understanding» (Luriia, 1998), adopted for the diagnoses of metaphoric understanding of idioms meaning by children; b) «The interpretation choice of one of the given variants of meanings» (Baskakova & Glukhov, 2008; Eliseeva, Gutsc & Marini, 2017); c) selection of one of several possible paraphrases (Winner, Rosenstiel & Gardner, 1976; Vosniadou & Ortony, 1983). Children were proposed to express themselves in order to find out how they understand given proverbs and idioms. If they had difficulties in meaning explication, so they were proposed some variants of proverbs and idioms interpretations, among which the first was correct (with indirect meaning) and the second with the direct meaning and the third with occasional associative meaning. The experiment proved such results: there are children with obvious intuitive language ability to feel the general meaning of proverbs and idioms. The part of children of the age of five years is able to verbalize the indirect proverb meaning (4,2%) and idioms meaning (7,4%). In the situation with one variant of meaning among some paraphrases 16,4% of children chose the correct proverb meaning, 20,4% of children chose the correct idiom meaning. More difficult for children’s understanding are proverbs, than idioms. It could be explained in the way, that idiomatic expressions are one whole and one nomination that a child often interprets in daily life from adults in some specific life situations. That is why he or she uses more quickly the heard word complex in a new association chain, abstracting from the direct meaning of idiomatic words. The proverb understanding is seen by child as more complex cognitive task, which foresees decipherment of the common thought or conclusion, understanding its meaning (implication). That is why the proverbs cause more problems among children than idioms.
The comparison of effectiveness of two variants of preventive anesthesia/analgesia in cancer surgery
Authors: Lisnyy I I 
Published: November 2018

Despite modern drugs and technologies in medicine, the questions of adequate analgesia in the postoperative period remain quite relevant. The effectiveness of preventive analgesia in the perioperative period remains a contentious issue.
The study included 53 oncosurgical patients. Gr.1 received dexketoprofen in combination with paracetamol for perioperative analgesia before the operation, Gr.2 the same medication was given before closing the operating wound. Anesthesia in both groups included an inhaled (Sevoran) and an extended epidural.
The study showed that the pain intensity on ANI monitoring and the total dose of fentanyl was less in Gr.1, compared to Gr.2. Cortisol plasma level and the level of glycemia in the perioperative period were less in patients in Gr.1 than in Gr.2. Pain intensity after surgery during first postoperative day was lower in Gr.1, then in Gr.2.
The administration of multimodal analgesia with paracetamol and dexketoprofen prior to the surgical interventions provides for the best quality of perioperative analgesia in oncological surgical interventions.
